[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the embodiments of the present invention; the terms used in the description of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention; the terms "including" and "having" in the description and claims of the embodiments of the present invention and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the description and claims of the embodiments of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0032] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the embodiments of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] In order to enable persons skilled in the art to better understand the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] See also Figure 1 An embodiment of the present application provides a thruster 1000, wherein the thruster 1000 is provided with a receiving cavity 100, wherein a heat source 200 and an electric control device 300 are received in the receiving cavity 100, wherein the temperature around the heat source 200 is higher than the temperature around the electric control device 300, and the thruster 1000 is further provided with a condensation elimination structure 400, wherein the condensation elimination structure 400 is used to prevent condensation from forming in the receiving cavity 100, or to absorb condensation to prevent condensation from contacting the electric control device 300.

[0035] It is understandable that the propeller 1000 of the present application can be installed on a movable device in water areas, and the movable device in water areas can be a boat. For example, it can be installed outside the boat as an outboard motor, or it can be installed on the bottom of the boat as a pod propeller 1000. The propeller 1000 of the present application is intended to propel the boat to move by outputting propulsion power, and the installation position of the propeller 1000 is not specifically limited. The boats that the propeller 1000 can be used for can be yachts, passenger ships, bamboo rafts, kayaks, and other water transportation vehicles without specific limitations.

[0036] Since the propeller 1000 is applied to boats and the boats travel on the water surface, the propeller 1000 will inevitably face more water vapor (water vapor in the air) on the water surface. In this embodiment, the propeller 1000 can prevent external water from penetrating into the propeller 1000 in terms of waterproof requirements. It can be understood that the better the waterproof performance, the worse the gas flowability inside the propeller 1000. However, because the absolute complete gas sealing requirement cannot be achieved, the propeller 1000 will always be mixed with external gas due to the assembly gap or dynamic sealing structure, and the external gas will bring water vapor into the propeller 1000, thereby causing the formation of condensation, which poses a danger to the propeller 1000.

[0037] The thruster 1000 of the present application utilizes the condensation elimination structure 400 to prevent condensation from forming in the receiving cavity 100 or absorb the formed condensation to avoid the condensation from contacting the electronic control device 300, thereby preventing the electronic control device 300 from being damaged due to contact with the condensation, thereby improving the safety of the thruster 1000.

[0038] The propeller 1000 of the embodiment of the present application is illustrated as an outboard motor. The heat source 200 of the propeller 1000 is the heat caused by energy loss when the propeller 1000 is working. That is to say, when the propeller 1000 is working, the heat of the heat source 200 is inevitable. Since the propeller 1000 needs to dissipate the heat generated by the heat source 200 in time to avoid the accumulation of heat and prevent the local temperature in the propeller 1000 from being too high, causing damage to certain devices, a temperature difference will be formed in the propeller 1000 from the high temperature of the heat source 200 to the cooled low temperature. After water vapor enters the propeller 1000, the water vapor will condense to form condensation when it encounters a temperature difference. In other words, the greater the temperature difference in the propeller 1000, the more serious the formation of condensation. As the power of the propeller 1000 increases, the high-power output means that more energy loss causes the heat source 200 to heat more seriously, thereby causing more condensation to form. The propeller 1000 of the present application is provided with a condensation elimination structure 400, so as to maintain high-power operation of the propeller 1000. The high-power operation of the propeller 1000 referred to in the present application means that the operating power of the propeller 1000 is at least greater than 10KW.

[0039] In this embodiment, the receiving chamber 100 is a sealed chamber that is at least waterproof to prevent water from the outside from directly penetrating into the receiving chamber 100, thereby avoiding short-circuit damage to the electronic control device 300 caused by water. The receiving chamber 100 is formed by assembling multiple parts of the propeller 1000, and the assembly of the multiple parts is sealed by setting a sealing structure. The receiving chamber 100 can be formed by multiple cavities connected to each other. The multiple cavities can refer to cavities distributed on different parts of the propeller 1000. Of course, the receiving chamber 100 can also include two incompletely isolated cavities, and the incomplete isolation of the two cavities means that the two cavities are isolated by a detachable device, and when the detachable device is removed, the connection between the two cavities can still be achieved.

[0040] In this embodiment, the heat source 200 and the electric control device 300 are both contained in the containing chamber 100. The heat source 200 generates heat mainly because the heat source 200, as a part of the propulsion power output of the propeller 1000, bears the important role of energy conversion, so there will be heat generation of the heat source 200. This means that the amount of heat generated by the heat source 200 is positively correlated with the amount of propulsion power that the propeller 1000 can output. Part of the heat emitted by the heat source 200 will be taken away by the cooling structure provided by the propeller 1000, and the other part will be conducted to the surrounding of the electric control device 300 with the air in the containing chamber 100. As a control circuit, the higher temperature of the electric control device 300 will affect the current transmission of the electric control device 300 and affect the operation of the electric control device 300, so the electric control device 300 is usually arranged in a lower temperature place in the containing chamber 100 of the propeller 1000, or the cooling structure is used to actively cool the electric control device 300. That is to say, the electric control device 300 needs to be in an environment with a lower temperature than the heat source 200 to maintain a good working state, that is, the temperature around the heat source 200 is higher than the temperature around the electric control device 300. That is to say, a temperature difference will be formed from the surrounding of the heat source 200 to the surrounding of the electric control device 300, and the temperature difference increases the possibility of condensation forming around the electric control device 300, that is, when the gas introduced into the receiving chamber 100 contains water vapor, the possibility of water vapor forming condensation around the electric control device 300 when it encounters cold increases, and the possibility of the electric control device 300 contacting with condensation also increases. Whether the condensation elimination structure 400 prevents condensation from forming in the receiving chamber 100 or absorbs condensation, it ultimately prevents condensation from contacting the electric control device 300, so that there is no need to suppress the temperature difference from the heat source 200 to the electric control device 300, and there is no need to suppress the heat generation of the heat source 200 to affect the effectiveness of the propeller 1000, nor is there any need to suppress the heat dissipation of the electric control device 300 to affect the operation of the electric control device 300. With the condensation elimination structure 400 to deal with condensation, the thruster 1000 can significantly increase the propulsion power, that is, there is no need to worry about the temperature difference problem caused by excessive heat generated by the heat source 200 due to the increase in power, and the electronic control device 300 can still be in a relatively low temperature state to meet the heat dissipation requirements, maintain a good working state, and maintain the normal operation of the thruster 1000.

[0041] Of course, it is understandable that, as a possible way, there may be an area in the receiving chamber 100 with a lower temperature than the area where the electronic control device 300 is located, and this is inevitable, and it will be the main situation for condensation to form in the receiving chamber 100. If the temperature concentration in the receiving chamber 100 is to be avoided, a certain area of ​​the receiving chamber 100 will inevitably be considered as a heat dissipation area, that is, there needs to be an area to dissipate heat to the external environment with a lower temperature, and this area is the low-temperature area in the receiving chamber 100. In other words, the receiving chamber 100 has a heat dissipation inner wall, and the heat dissipation inner wall is used to exchange the heat in the receiving chamber 100 with the external environment. Since the heat dissipation inner wall of the receiving chamber 100 exchanges heat with the external environment, the heat in the receiving chamber 100 is output to the external environment through the heat dissipation inner wall, which causes the water vapor in the receiving chamber 100 to be heated by the heat source 200 and may form condensation on the heat dissipation inner wall when it is cooled. Although the heat dissipation inner wall may be at a certain distance from the electronic control device 300, it is still possible that the condensation moves to the electronic control device 300 under the influence of its own gravity or vibration or shaking, and contacts the electronic control device 300. The condensation elimination structure 400 is intended to prevent any condensation in the receiving chamber 100 that may contact the electronic control device 300, so there is no need to suppress the temperature difference from the heat source 200 to other areas outside the vicinity of the electronic control device 300, so as to ensure that the thruster 1000 has relatively good parameter conditions.

[0042] For an example, see Figure 2 The heat source 200 includes a first motor 210 , and the first motor 210 is used to drive the propeller 220 to rotate. The electronic control device 300 includes a driver 310 electrically connected to the first motor 210 .

[0043] In this embodiment, the first motor 210 is located in the receiving chamber 100. The first motor 210 includes a stator and a rotor. The stator is fixed to the inner wall of the receiving chamber 100. The rotor cooperates with the stator. The electromagnetic forces of the stator and the rotor interact with each other to realize the rotation of the rotor. The rotor drives the propeller 220 to rotate using the motor shaft. The propeller 220 is located outside the receiving chamber 100. The propeller 220 rotates in the water to realize the propeller 1000 outputting propulsion power. The rotor of the first motor 210 can be directly connected to the propeller 220 via the shaft, or it can be connected to the propeller 220 via the shaft and the transmission mechanism. The driver 310 is located in the receiving chamber 100. The driver 310 includes a motor control board and a power control board electrically connected to the motor control board. The motor control board is electrically connected to the first motor 210 for controlling the speed, direction, and torque of the first motor 210. The power control board is electrically connected to the first motor 210 for controlling the power of the first motor 210. The driver 310 includes an input terminal 311 and an output terminal 312. The input terminal 311 is connected to direct current from the power battery, and the output terminal 312 outputs three-phase alternating current to the first motor 210. The input terminal 311 is connected to high voltage electricity above 96V to meet the high power requirements of the first motor 210. The power battery can be located in the receiving chamber 100, or outside the receiving chamber 100, or it can be independent of the thruster 1000 and connected to the thruster 1000 through a current harness. Of course, the driver 310 can also obtain current from other power sources such as generators, solar panels, hydrogen fuel cells, etc.

[0044] It is understandable that the connecting shaft between the first motor 210 and the propeller 220 partially extends into the receiving chamber 100, and there must be a dynamic seal with the housing where the receiving chamber 100 is located. For example, in a possible implementation, the rotating shaft connected to the propeller 220 partially extends into the receiving chamber 100, and an oil seal structure is used to dynamically seal the part of the rotating shaft that cooperates with the receiving chamber 100. In an implementation in which the battery is located outside the receiving chamber 100, the wiring harness connecting the battery and the driver 310 penetrates into the receiving chamber 100 and is sealed with the receiving chamber 100 to ensure the sealing and waterproof performance of the receiving chamber 100.

[0045] It is understandable that the first motor 210 and the driver 310 are housed together in the housing chamber 100, which facilitates the connection between the first motor 210 and the driver 310 and also makes the structure of the propeller 1000 more compact. The first motor 210 generates heat when driving the propeller 220 to rotate, and the driver 310 also generates heat when driving the first motor 210 to operate, but the working temperature of the first motor 210 is higher than the working temperature of the driver 310. In order to facilitate the better heat dissipation of the driver 310, the driver 310 is usually close to the area of ​​the housing chamber 100 that is easy to dissipate heat to the external environment, or a cooling structure is set to dissipate heat for the driver 310. The condensation elimination structure 400 prevents condensation from contacting the driver 310. The condensation elimination structure 400 can prevent the water vapor in the housing chamber 100 from being heated by the heat of the first motor 210 and forming condensation around the driver 310 or other low-temperature areas in the housing chamber 100, and can also absorb the condensation formed by the water vapor in the housing chamber 100 being cooled, so as to avoid the condensation from contacting the driver 310 and causing damage to the driver 310.

[0046] As a possible implementation, the first motor 210 is provided with a double-winding electromagnetic coil arranged side by side, that is, the first motor 210 may be provided with a double stator and a double rotor structure arranged side by side, so as to improve the power of the first motor 210, reduce the diameter of the first motor 210, and reduce the difficulty of manufacturing the first motor 210. In this case, since the first motor 210 is provided with a double-winding electromagnetic coil, the first motor 210 generates more heat when it is running, so the temperature difference formed in the receiving chamber 100 is larger. The condensation elimination structure 400 can eliminate the contact between the condensation in the receiving chamber 100 and the driver 310, so as to allow the power of the first motor 210 to increase. In order to drive the first motor 210 to run, the hidden danger of condensation is eliminated by the condensation elimination structure 400, and the driver 310 can be provided to include a double power control board, and the double power control board is used to control the double-winding electromagnetic coils of the first motor 210 respectively, thereby ensuring the operation of the driver 310 and increasing the operating power of the first motor 210.

[0047] In this embodiment, the receiving chamber 100 has a pod area 110 located in the underwater part of the propeller 1000, and the first motor 210 is located in the pod area 110. When the propeller 1000 outputs propulsion power, the propeller 220 needs to be lowered into the water, and part of the propeller 1000 must be located underwater. The propeller 1000 has an underwater part, and the pod area 110 is the inner cavity of the underwater part. The first motor 210 is located in the pod area 110. The heat generated by the first motor 210 during operation can be well dissipated to the external water through the pod area 110, so as to achieve rapid cooling of the first motor 210. The part of the propeller 1000 that wraps the first motor 210 underwater can be understood as a cooling mechanism for cooling the first motor 210, so as to avoid all the heat of the first motor 210 from accumulating in the receiving chamber 100.

[0048] In this embodiment, the heat source 200 includes a reducer 230, and the reducer 230 is connected to the first motor 210 and the propeller 220. The reducer 230 includes a plurality of continuously meshed gears. The reducer 230 can reduce the speed of the torque output by the first motor 210, and increase the torque output to the propeller 220 to increase the propulsion power of the propeller 220, thereby increasing the power of the propeller 1000. When the first motor 210 is running, the friction between the plurality of gears will cause heat, resulting in an increase in the temperature of the reducer 230. In order to avoid the reducer 230 from failing due to excessive temperature, a heat conducting medium is provided in the pod area 110 to conduct the heat of the reducer 230 to the outer shell that wraps the reducer 230, and the outer shell then conducts the heat to the external water. The heat conducting medium can be heat conducting oil, which can also lubricate the reducer 230. Although part of the heat of the reducer 230 is dissipated to the external water through the heat-conducting medium to achieve cooling, some heat will still be conducted to other areas of the pod area 110 of the housing cavity 100. The condensation elimination structure 400 can eliminate the condensation formed thereby to reduce the occurrence rate of safety failure of the electronic control device 300 caused by the heating of the reducer 230.

[0049] In this embodiment, the receiving chamber 100 has a nose area 120 located in the above-water part of the propeller 1000, and the nose area 120 accommodates a second motor 320. The second motor 320 is used to drive the propeller 1000 to turn. The electronic control device 300 includes a steering controller 330 located in the nose area 120, and the steering controller 330 is electrically connected to the second motor 320.

[0050] In this embodiment, the nose region 120 is located at the top of the propeller 1000, and the driver 310 is located in the nose region 120, which is convenient for disassembly and maintenance of the driver 310, and also convenient for the driver 310 to connect the battery and the first motor 210 located in the pod region 110. Of course, in other embodiments, the driver 310 may also be located between the nose region 120 and the pod region 110, or the driver 310 may be completely located in the pod region 110.

[0051] In this embodiment, the propeller 1000 is installed on the transom of the hull 2000, and the propeller 1000 is provided with a steering shaft 321, and the propeller 1000 is steered relative to the hull 2000 via the steering shaft 321. The second motor 320 is a steering motor, and the second motor 320 outputs a steering torque to the steering shaft 321 to achieve the steering of the propeller 1000. It is understandable that a steering reduction mechanism 322 can also be provided between the second motor 320 and the steering shaft 321 to increase the steering torque of the second motor 320. The second motor 320 is located in the receiving chamber 100, which is convenient for protecting the second motor 320, and for facilitating the electrical connection between the second motor 320 and the steering controller 330, thereby reducing the wiring harness between the second motor 320 and the steering controller 330. The working voltage of the steering controller 330 is a low voltage, for example, the steering controller 330 can be connected to 6V, 12V, 18V, and 24V voltages. The steering controller 330 is fixed to the inner wall of the nose area 120 via a bracket. The condensation elimination structure 400 prevents condensation from contacting the steering controller 330 , thereby ensuring the safety of the steering controller 330 and maintaining the effective steering function of the thruster 1000 .

[0052] In this embodiment, the propeller 1000 is equipped with a third motor 350 , and the third motor 350 is used to drive the propeller 1000 to lift. The electronic control device 300 includes a lift controller 370 located in the head area 120 , and the lift controller 370 is electrically connected to the third motor 350 .

[0053] In this embodiment, the propeller 1000 is equipped with a tilting fixture 360, and the tilting fixture 360 ​​includes a fixed fixture 361 and a rotating bracket 362. The rotating bracket 362 and the fixed fixture 361 are connected via a tilting axis 363, and the rotating bracket 362 can rotate around the tilting axis 363. The fixed fixture 361 is fixed to the transom of the hull 2000. The steering shaft 321 of the propeller 1000 is connected to the rotating bracket 362 to achieve steering relative to the hull 2000. A tilting transmission mechanism is also provided between the fixed fixture 361 and the rotating bracket 362, and the third motor 350 outputs power to the tilting transmission mechanism to drive the rotating bracket 362 to tilt and rotate relative to the hull 2000 around the tilting axis 363. The tilting fixture 360 ​​is located outside the receiving chamber 100, so that the propeller 1000 can tilt relative to the hull 2000, and the third motor 350 is located outside the receiving chamber 100, so that the power is output to the tilting transmission mechanism. The lifting transmission mechanism may include a telescopic rod, or a worm gear transmission mechanism, or a transmission mechanism such as a screw nut. The lifting controller 370 is electrically connected to the third motor 350 to control the output power, direction, speed, etc. of the third motor 350 to control the lifting direction and lifting rate of the propeller 1000. Of course, in this embodiment, the lifting actuator of the propeller 1000 may also be an electro-hydraulic lifting actuator, that is, the lifting actuator includes a motor and a hydraulic cylinder to output the lifting power.

[0054] In this embodiment, the lifting controller 370 is close to the steering controller 330, which is convenient for the wiring layout of the low voltage power supply connecting the lifting controller 370 and the steering controller 330. The lifting controller 370 is connected to a low voltage, for example, the steering controller 330 can be connected to a 6V, 12V, 18V, 24V voltage. The lifting controller 370 can be fixed on the same bracket as the steering controller 330. The steering controller 330 and the lifting controller 370 are close to each other, which is convenient for the condensation elimination structure 400 to prevent condensation from contacting the steering controller 330 and the lifting controller 370 at the same time, thereby maintaining the steering and lifting functions of the propeller 1000.

[0055] In one embodiment, the tilting controller 370 and the steering controller 330 are stacked together, so that the tilting controller 370 and the steering controller 330 can be separately disassembled and maintained. The tilting controller 370 and the steering controller 330 can be fixed on opposite sides of the bracket respectively.

[0056] Another embodiment is provided, where the tilting controller 370 is integrated with the steering controller 330. The tilting controller 370 and the steering controller 330 are integrated with the same circuit board, thereby reducing the manufacturing cost and compressing the volume of the propeller 1000.

[0057] In this embodiment, the electronic control device 300 includes a central controller 380, which is responsible for processing the interactive control of the propeller 1000 and external devices. The central controller 380 is electrically connected to the tilting controller 370, the steering controller 330, and the driver 310. The central controller 380 is used to obtain the feedback signals collected by the tilting controller 370, the steering controller 330 and the driver 310, so as to feed back the information such as the tilting, steering and propulsion of the propeller 1000 to the external interactive system, and the user can control the operation of the propeller 1000 based on the interactive system. The interactive system includes but is not limited to display screens, near handles, remote control throttles, side throttles and other devices. The central controller 380 is electrically connected to the interactive system to realize communication with the interactive system. The central controller 380 is also responsible for electrically connecting to the battery management system to realize communication with the battery management system. The central controller 380 is also responsible for communicating with the cloud server, so as to upload the operating data of the propeller 1000, the battery, the interactive system and other devices to the cloud server, and download historical data from the cloud server for analysis and processing. The condensation elimination structure 400 can prevent condensation from contacting the central controller 380, thereby ensuring the normal operation of the central controller 380, thereby achieving effective system management of the thruster 1000, the interactive system and the battery.

[0058] In this implementation, please refer to Figure 2 and Figure 3 , the receiving chamber 100 has a top area away from the heat source 200, the central controller 380 is located in the top area, the top area is provided with a closed box, and the central controller 380 is located in the closed box. Specifically, the propeller 1000 is provided with a cover 1100, and the cover 1100 covers the top area, thereby covering the top area. A groove 1101 is provided inside the cover 1100, and the central controller 380 is accommodated in the groove 1101. The propeller 1000 also includes a partition 1102 located in the receiving chamber 100 and sealed with the cover 1100. The partition 1102 covers the groove 1101 so that the partition 1102 and the cover 110 form a closed box, and then the central controller 380 is located in the isolation area. Since the central controller 380 is easily interfered with and has high waterproof requirements, the central controller 380 is arranged in the isolation area to further ensure the safety of the central controller 380.

[0059] In this implementation, please refer to Figure 3 and Figure 4, the receiving chamber 100 is a sealed chamber, and the thruster 1000 is provided with a valve 1200 connected to the receiving chamber 100, and the valve 1200 is a waterproof and breathable valve, and the valve 1200 allows external gas to enter and exit the receiving chamber 100, and prohibits external water from entering the receiving chamber 100. The sealed chamber is intended to be a sealed chamber that can prevent water from entering, but it is not an absolutely airtight chamber. In other words, the receiving chamber 100 can prevent water from infiltrating, but it cannot prevent gas from entering and exiting due to the assembly gaps of the various parts of the thruster 1000. In this embodiment, it is not desired that the receiving chamber 100 achieves absolute air sealing, but a valve 1200 is provided to achieve the effect of allowing the receiving chamber 100 to breathe gas. It is understandable that, based on the fact that the heat source 200 is contained in the receiving chamber 100, the heat source 200 emits heat when it is in operation, so that the heat source 200 will heat the temperature in the receiving chamber 100, increase the air pressure in the receiving chamber 100, and the gas in the receiving chamber 100 will be exhaled from the valve 1200 to achieve pressure relief in the receiving chamber 100 and protect the receiving chamber 100. When the heat source 200 stops working, the temperature in the receiving chamber 100 decreases, and the air pressure in the receiving chamber 100 decreases, so that the gas is inhaled through the valve 1200 to maintain the normal air pressure in the receiving chamber 100. It is understandable that the partition 1102 is intended to isolate the electromagnetic signal interference to the central controller 380, and to isolate most of the possible water from contacting the central controller 380. The partition 1102 does not isolate the flow of gas, and is intended to ensure that the valve 1200 can breathe the gas in the receiving chamber 100 to release the increase in air pressure caused by the heat of the heat source 200.

[0060] Furthermore, the valve 1200 is opened at the top of the propeller 1000 and on the side wall facing away from the windward side.

[0061] In this embodiment, the propeller 1000 has a windward side and a tail side facing away from the windward side. The windward side is the side that faces the wind resistance when the propeller 1000 propels the hull 2000 forward. The tail side does not face the wind resistance. The windward side and the tail side are both located at the nose 1300 of the propeller 1000. The valve 1200 is arranged on the tail side 1002 to prevent the valve 1200 from absorbing unnecessary airflow into the receiving chamber 100 against the wind. The valve 1200 is arranged at the top of the tail side 1002 to facilitate the disassembly and maintenance of the valve 1200.

[0062] It is understandable that the valve 1200 allows the receiving chamber 100 to breathe gas to maintain the air pressure in the receiving chamber 100 stable, thereby maintaining the normal operation of the components in the receiving chamber 100. In the case where the gas inhaled by the valve 1200 inevitably contains water vapor, the condensation elimination structure 400 can prevent condensation from forming in the receiving chamber 100, or can eliminate the condensation formed in the receiving chamber 100, thereby allowing the valve 1200 to maintain the function of breathing gas normally, and can ensure the safety of the electronic control components 300 in the receiving chamber 100, and ensure that the heat source 200 works normally in the receiving chamber 100 and outputs power effectively.

[0063] In one embodiment, see Figure 4 The condensation elimination structure 400 includes a partition 410, which separates the electric control device 300 from the heat source 200 to prevent the heat source 200 from heating the electric control device 300 and the water vapor around it, causing the water vapor to condense after heating.

[0064] In this embodiment, the partition 410 is arranged in the receiving cavity 100. The partition 410 divides the receiving cavity 100 into two cavities, and the electric control device 300 and the heat source 200 are respectively received in the two cavities. The gas in the cavity where the heat source 200 is located cannot pass through the partition 410 to the cavity where the electric control device 300 is located, so the heat of the heat source 200 cannot be brought to the cavity where the electric control device 300 is located, and the water vapor in the cavity where the electric control device 300 is located cannot be heated and then encounter cold to form condensation. In other words, the partition 410 isolates the gas flow between the cavity where the heat source 200 is located and the cavity where the electric control device 300 is located, so that the heat in the heat source 200 cannot be conducted to the surrounding of the electric control device 300 through the gas, and it is also impossible to heat the water vapor in the gas around the electric control device 300, and the water vapor cannot be heated and then encounter cold to form condensation, thereby eliminating the condensation in the cavity where the electric control device 300 is located, and ensuring the safety of the electric control device 300. In this embodiment, the elimination of condensation does not mean absolutely eliminating the formation of condensation, but refers to eliminating condensation that poses a contact hazard to the electronic control device 300, that is, reducing the amount of condensation formed until it does not pose a contact short circuit hazard to the electronic control device 300.

[0065] For further information, see Figure 5 The receiving chamber 100 is a sealed chamber, and the receiving chamber 100 has a pod area 110 located in the underwater part of the propeller 1000 and a nose area 120 located in the above-water part. The heat source 200 is located in the pod area 110, and the electronic control device 300 is located in the nose area 120. The partition 410 separates the pod area 110 and the nose area 120 into two independent sealed areas.

[0066] In this embodiment, the propeller 1000 includes a nose 1300, a duct 1400 connected to the nose 1300, and a pod 1500 connected to the duct 1400. The mechanism area is arranged at the nose 1300, and the pod area 110 is arranged at the pod 1500. Usually, the nose 1300 is located above the water, and the pod 1500 is located underwater. The nose 1300 is used to connect to the hull 2000 to transmit propulsion force to the hull 2000. The pod 1500 outputs propulsion power underwater. The heat source 200 is located in the pod area 110, and the heat generated by the heat source 200 can be quickly dissipated to the external water through the outer shell of the pod 1500, so as to avoid the heat accumulation in the pod area 110 causing the propeller 1000 to malfunction. The electronic control device 300 is located in the nose area 120 away from the water, thereby avoiding the risk of the electronic control device 300 contacting water. Even if the pod 1500 is damaged and flooded due to an accidental impact, the water located in the pod area 110 will not reach the nose area 120, and the electronic control device 300 located in the nose area 120 will not short-circuit with the water due to water seepage, and the electronic control device 300 can still maintain normal operation, for example, it can prompt the user of a fault, automatically cut off the power, and maintain normal control of the above-water device. The partition 410 can be set in the conduit 1400, or it can be set at the position where the conduit 1400 connects to the nose 1300, or it can be set at the position where the conduit 1400 connects to the pod 1500. In this embodiment, the partition 410 is intended to separate the two cavities where the heat source 200 and the electronic control device 300 are located, and the specific position of the partition 410 in the propeller 1000 is not limited to the above possible implementation methods. Of course, in other embodiments, the propeller 1000 may also only include the nose 1300 and the pod 1500, the pod 1500 is directly connected to the nose 1300, and the partition 410 is located at the position where the pod 1500 and the nose 1300 are connected.

[0067] exist Figure 5 In the embodiment of the present invention, the heat source 200 includes a first motor 210, the electric control device 300 includes a driver 310 electrically connected to the first motor 210, the driver 310 is connected to the first motor 210 via a conductive member 500, and the partition 410 is sealed with the conductive member 500. It can be understood that the partition 410 needs to be sealed with the inner wall of the receiving cavity 100 and the conductive member 500. The partition 410 and the conductive member 500 are sealed to ensure that the conductive member 500 can pass through the partition 410, and the first motor 210 and the driver 310 conduct current to each other.

[0068] See also Figure 5 , Figure 6 and Figure 7In one embodiment, the propeller 1000 includes an upper shell 700 and a lower shell 600 fixed to the upper shell 700, the nose area 120 is formed on the upper shell 700, the pod area 110 is formed on the lower shell 600, and the partition 410 is close to the connection between the upper shell 700 and the lower shell 600.

[0069] In this embodiment, the upper shell 700 is sealed and connected with the lower shell 600 to avoid water seepage between the upper shell 700 and the lower shell 600. Specifically, a part of the lower shell 600 can be inserted into the upper shell 700 for sealing, or a part of the upper shell 700 can be inserted into the lower shell 600 for sealing. The fixed connection between the upper shell 700 and the lower shell 600 can be that the flange of the upper shell 700 and the flange of the lower shell 600 are locked and fixed by bolts, and of course, they can also be locked and fixed by pins. The sealing fit between the upper shell 700 and the lower shell 600 can be sealed by using a sealing rubber ring. As a preferred embodiment, the sealing rubber ring is arranged between the fastening and fitting surfaces of the flange of the upper shell 700 and the flange of the lower shell 600 to enhance the elastic deformation degree of the sealing rubber ring and increase the sealing performance.

[0070] It can be understood that the partition 410 separates the pod area 110 from the nose area 120, which does not mean that the pod area 110 and the nose area 120 cannot be ventilated. When the temperature of the first motor 210 rises greatly and the air pressure in the pod area 110 is high, the gas pressure will break through the sealing pressure of the partition 410, and the gas will leak from the fine gap between the partition element and the inner wall of the receiving cavity 100 or the fine gap of the conductive wire bundle, so that part of the gas will slowly leak into the nose area 120, thereby ensuring the pod area The pressure is released in 110, and the gas slowly leaks into the head area 120, causing the heating rate of the head area 120 to slow down. The heating rate of the head area 120 will not exceed the heat dissipation and cooling rate. The moisture in the head area 120 can reduce the situation where condensation is formed after rapid heating and then encountering cold. Therefore, the valve 1200 on the head 1300 can still maintain the breathing of the gas in the receiving chamber 100 and keep the air pressure normal, but the head area 120 reduces the formation of condensation, thereby ensuring the safety of the electronic control device 300.

[0071] As a possible manner, the partition 410 may be located at the bottom of the upper shell 700, close to the portion of the lower shell 600 extending into the upper shell 700. When the lower shell 600 is assembled with the upper shell 700, it is convenient to first install the partition 410 into the upper shell 700, and then install the end of the lower shell 600 into the upper shell 700. Of course, in another possible manner, the partition 410 may be located at the top of the lower shell 600, close to the portion of the upper shell 700 extending into the lower shell 600.

[0072] Specifically, the lower shell 600 is provided with a pod shell 610 and a lower conduit 620 for fixing the pod shell 610, the upper shell 700 is provided with a head shell 710 and an upper conduit 720 for fixing the head shell 710, the lower conduit 620 is sealed and connected with the upper conduit 720, the partition 410 is located in the lower conduit 620 or the upper conduit 720, and is sealed and matched with the inner wall of the lower conduit 620 or the inner wall of the upper conduit 720, the conductive member 500 is provided with a harness 530, and the partition 410 is provided with a harness hole 411 for sealing and matching with the harness 530. The lower shell 600 and the lower conduit 620 are integrally formed to reduce the assembly gap and reduce the water seepage position of the receiving chamber 100. Since the upper shell 700 is located above the water and is less likely to contact with water, in order to reduce the manufacturing cost, the head shell 710 and the upper conduit 720 can be sealed and assembled. One end of the upper duct 720 is fastened to the nose housing 710 and sealed to maintain the sealing of the nose area 120. The other end of the upper duct 720 is fastened to and sealed to an end of the lower duct 620 away from the pod housing 610. The cross-sectional shapes of the lower duct 620 and the upper duct 720 are similar, both of which are wedge-shaped to reduce the water resistance of the lower duct 620 and the upper duct 720.

[0073] In this embodiment, the first motor 210 is located in the pod shell 610, and the driver 310 is located in the nose shell 710. The wiring harness 530 connecting the driver 310 and the first motor 210 passes through the upper duct 720 and the lower duct 620. The length of the upper duct 720 is greater than the length of the lower duct 620. A wave crushing plate 721 is provided at the bottom end of the upper duct 720, and the wave crushing plate 721 protrudes from one side of the upper duct 720. The wave crushing plate 721 is used to reduce the wave-making resistance of the propeller 1000. Of course, in other embodiments, the wave crushing plate 721 can also be provided at the top end of the lower duct 620. The length of the upper duct 720 is less than the length of the lower duct 620. The upper duct 720 can also be integrally formed with the nose shell 710. In some possible embodiments, a duct can also be provided between the nose shell 710 and the pod shell 610.

[0074] In this embodiment, the end of the lower conduit 620 is provided with a boss 621 extending into the upper conduit 720, at least one sealing ring is arranged between the outer peripheral side wall of the boss 621 and the inner peripheral side wall of the upper conduit 720, and the boss 621 is provided with a wire passing hole 622, and the protruding direction of the boss 621 is parallel to the length direction of the lower conduit 620. The protruding height of the boss 621 is based on allowing at least one sealing ring to be assembled, thereby increasing the sealing performance between the lower conduit 620 and the upper conduit 720. Of course, at least two sealing rings can also be assembled on the peripheral side of the boss 621. The cross-sectional shape of the boss 621 is roughly similar to the cross-sectional shape of the upper conduit 720, and a wedge shape is adopted, thereby increasing the cross-sectional shape of the boss 621 to allow enough wire harnesses 530 to pass through the boss 621. The wire passing hole 622 can be one or more. For example, the boss 621 is provided with a wire passing hole 622, and the wire passing hole 622 allows the entire wire harness 530 to pass through. The boss 621 is provided with a plurality of wire holes 622, and the plurality of wire holes 622 respectively allow a plurality of cables of the wire harness 530 to pass through. The wire holes 622 are communicated with the inner cavity of the downpipe 620, and the inner cavity of the downpipe 620 is communicated with the inner cavity of the pod housing 610, so that one end of the wire harness 530 can be assembled to the pod area 110.

[0075] In this embodiment, the bottom end of the upper conduit 720 is provided with a mounting groove 1101 assembled with the boss 621, and the inner peripheral side wall of the mounting groove 1101 is gap-matched with the outer peripheral side wall of the boss 621. At least two sealing rings seal the assembly gap between the boss 621 and the mounting groove 1101. The mounting groove 1101 is connected to the inner cavity of the upper conduit 720 to guide the wiring harness 530 to pass through the upper conduit 720. The depth of the mounting groove 1101 is at least greater than the height of the boss 621, and allows a portion of the partition 410 to be installed in the mounting groove 1101, thereby achieving the limit and stability of the partition 410.

[0076] For details, please refer to Figure 6 , Figure 7 and Figure 8, the installation groove 1101 is away from the bottom of the lower conduit 620 to form a limiting platform 722. A sealing hole 523 connected to the installation groove 1101 is provided in the upper conduit 720, and the sealing hole 523 is connected to the inner cavity of the upper conduit 720. The upper conduit 720 is provided with a sealing hole 523 extending to the limiting platform 722. The partition 410 is provided with a column 412 assembled with the sealing hole 523, and a limiting flange 413 arranged around the column 412. The limiting flange 413 is located in the groove 1101, and the boss 621 of the lower conduit 620 abuts against the end of the column 412, so that the limiting flange 413 abuts against the limiting platform 722, thereby achieving stable limiting of the partition 410. At least two sealing rings can be assembled on the side of the column 412 and the sealing fit, so as to use the sealing ring to seal the assembly gap between the column 412 and the sealing hole 523, so as to achieve a sealing fit between a part of the partition 410 and the sealing hole 523. The limiting flange 413 is abutted against the limiting platform 722, so as to achieve another part of the partition 410 abutting against the limiting platform 722. The column 412 is sealed with the sealing hole 523 of the upper guide tube 720, so as to achieve the partition 410 blocking the path of the nose area 120 connecting the pod area 110, so as to achieve the partition 410 to separate the nose area 120 from the pod area 110.

[0077] More specifically, the harness hole 411 of the partition 410 includes 6 AC line holes and 1 signal line hole. The 6 AC line holes are divided into two groups of three-phase AC line holes, which are used to cooperate with two groups of three-phase AC lines. The two groups of three-phase AC lines are electrically connected to the two groups of stator windings of the first motor 210, and are connected to the output end 312 of the driver 310. One signal line hole is used to connect to the control line connected to the driver 310. The inner walls of the 6 AC line holes and the 1 signal line hole are provided with sealing coils to achieve a sealed fit between the harness hole 411 and the harness 530, so as to prevent hot air from leaking between the harness 530 and the partition 410 to the nose area 120, so as to achieve that the partition 410 completely separates the pod area 110 and the nose area 120.

[0078] For further information, please refer to Figure 6The upper conduit 720 is also provided with a heat-conducting cavity 524 isolated from the receiving cavity 100, and a heat-conducting pipe 425 connected to the driver 310 is provided in the heat-conducting cavity 524. The lower conduit 620 is provided with a cooling liquid cavity 624 isolated from the receiving cavity 100, and a liquid inlet and outlet port 6240 connected to the cooling liquid cavity 624. The liquid inlet and outlet port 6240 is sealed and connected to the heat-conducting pipe 425. The heat of the driver 310 is brought to the cooling liquid cavity 624 through the cooling liquid in the heat-conducting pipe 425, and heat is exchanged with external water at the lower conduit 620. The upper conduit 720 is provided with a cooling liquid flow channel that can be connected to the head cavity and the heat-conducting cavity 524. The head cavity is arranged in the head housing 710. The driver 310 is fixed to the bottom of the head cavity and sealed and docked with the cooling liquid flow channel, so that the driver 310 and the cooling liquid flow channel can transmit cooling liquid. The heat pipe 425 is connected to the coolant flow channel in the heat conduction cavity 524, and can transmit the coolant through the coolant flow channel. The inlet and outlet ports 6240 of the lower conduit 620 are arranged on the cover plate 623 and separated from the boss 621. The inlet and outlet ports 6240 transmit the coolant through the heat pipe 425. The coolant cavity 624 transmits the coolant through the inlet and outlet ports 6240. The coolant cavity 624 is located in the lower conduit 620, so the coolant in the coolant cavity 624 can exchange heat with the external water through the lower conduit 620, and the heat of the driver 310 is transferred to the water in the peripheral environment of the lower conduit 620 through the coolant, so as to achieve cooling and heat dissipation of the driver 310.

[0079] See also Fig. 9 , in another embodiment, with Figure 6 The embodiments are substantially the same, except that the partition 410 is close to the driver 310, and the driver 310 is located at the bottom of the upper shell 700, shortening the distance from the driver 310 to the pod area 110. The lower shell 600 is provided with a pod shell 610 and a conduit 1400 for fixing the pod shell 610, the end of the conduit 1400 is sealed and connected to the upper shell 700, the partition 410 is located at the end of the conduit 1400, the conductive member 500 is provided with a bus 540 electrically connected to the driver 310, the bus 540 is integrated with the partition 410, the driver 310 is held against the partition 410, and the conductive member 500 is further provided with a harness 530 passing through the conduit 1400 and connected to the bus 540.

[0080] Specifically, the upper housing 700 includes a head housing 710, and the head housing 710 is sealed and connected to the end of the conduit 1400 away from the pod housing 610. The driver 310 is located in the head housing 710. The bus 540 is arranged at the output end 312 of the driver 310, and the bus 540 is provided with a plurality of conductive terminals connected to the wiring harness 530. The plurality of conductive terminals pass through the partition 410. The partition 410 is sealed and matched with the inner wall of the conduit 1400, and is integrally formed with the plurality of conductive terminals, so that the partition 410 and the bus 540 can be connected to the driver 310 to form a module, and then the module can be installed in the bottom of the head housing 710, and the partition 410 can block the bottom of the head housing 710. The wiring harness 530 of the conductive member 500 is connected to the part of the bus 540 passing through the partition 410, and is connected to the first motor 210 in the pod housing 610 through the conduit 1400.

[0081] See also Fig.10 and Fig.11 , another embodiment is provided, which is substantially the same as the embodiment, except that the driver 310 is located in the underwater part of the propeller 1000, so that the driver 310 can be quickly cooled down. Specifically, the receiving chamber 100 is a sealed chamber, and the receiving chamber 100 has a pod area 110 located in the underwater part of the propeller 1000 and a head area 120 located in the above-water part, and a duct area 130 located between the pod area 110 and the head area 120, the heat source 200 is located in the pod area 110, a part of the electric control device 300 is located in the head area 120, and another part is located in the duct area 130, and the partition 410 separates the pod area 110, the duct area 130 and the head area 120 into three independent sealed areas.

[0082] Since the electric control device 300 is divided into multiple parts and arranged at different positions in the receiving cavity 100 according to needs, it is convenient to reasonably design the cable layout in the receiving cavity 100. A part of the electric control device 300 is located in the conduit area 130, which is convenient to use the environmental water outside the conduit area 130 to quickly cool down a part of the electric control device 300, avoiding damage caused by excessive temperature rise of part of the electric control device 300, and also conveniently connecting this part of the electric control device 300 to the heat source 200, so as to control the operation of the heat source 200. Another part of the electric control device 300 is located in the head area 120, which is convenient for this part to be away from water, prevent this part from contacting with water, ensure safety, and facilitate disassembly and maintenance of this part at the head 1300 position. The partition 410 separates the pod area 110, the duct area 130 and the head area 120 into three independent sealed areas, so that the heat dissipated by the heat source 200 in the pod area 110 is isolated from the duct area 130 and the head area 120, that is, the hot air in the pod area 110 will not enter the duct area 130 and the head area 120, and it is impossible to heat the water vapor in the duct area 130 and the head area 120 and then form condensation when it encounters cold. Since the duct area 130 is close to the pod area 110, some heat in the pod area 110 will still be conducted to the duct area 130 through the shell of the propeller 1000 and part of the partition 410, resulting in the possibility of temperature rise in the duct area 130. When the temperature in the duct area 130 rises, it will further cause the temperature of the nose area 120 to rise. The pod area 110, the duct area 130 and the nose area 120 are separated into three sealed cavities by the partition 410, thereby preventing hot air from flowing in the duct area 130 and the nose area 120 and causing a large temperature difference, thereby preventing condensation from forming in the duct area 130 and the nose area 120.

[0083] Specifically, the partition 410 includes a first partition element 414 and a second partition element 415. The first partition element 414 separates the nacelle region 110 and the duct region 130, and the second partition element 415 separates the duct region 130 and the head region 120. The first partition element 414 blocks the flow of gas between the nacelle region 110 and the duct region 130, and the second partition element 415 blocks the flow of gas between the duct region 130 and the head region 120, thereby preventing the heat of the heat source 200 in the nacelle region 110 from being transferred to the duct region 130 and then to the head region 120.

[0084] In this embodiment, the heat source 200 includes a first motor 210, and the electronic control device 300 includes a driver 310 electrically connected to the first motor 210. The driver 310 is located in the duct area 130 and is connected to the first motor 210 via a first conductive member 501. The first conductive member 501 is sealed with the first partition element 414. The driver 310 is electrically connected to the battery via a second conductive member 502, and the second conductive member 502 is sealed with the second partition element 415.

[0085] The first motor 210 is used to convert electrical energy into propulsion power. The driver 310 controls the operation of the first motor 210. The driver 310 is located in the duct area 130, which can reduce the length of the wiring harness between the driver 310 and the first motor 210, improve the accuracy of the driver 310 controlling the first motor 210, and facilitate the driver 310 to use the underwater environment for rapid heat dissipation. The first conductive member 501 is similar to the conductive member 500 of the illustrated embodiment. The first conductive member 501 can be assembled with the first partition element 414 and sealed, or it can be integrally formed. The input end 311 of the driver 310 needs to be connected to the DC wiring harness and the signal control line, that is, the second conductive member 502 includes a DC wiring harness and a signal control line. The DC wiring harness passes through the second partition element 415 to connect the battery, and the signal control line passes through the second partition element 415 to connect the central controller 380 and the interactive control device. The battery and the central controller 380 can be located in the nose area 120 or outside the propeller 1000. In this embodiment, the battery is located outside the propeller 1000, and the central controller 380 is located in the nose area 120. The sealing cooperation mode of the second conductive member 502 and the second partition element 415 can adopt the sealing cooperation mode of the conductive member 500 and the partition member 410 similar to the illustrated embodiment. The driver 310 and the central controller 380 are separated into two different areas, which is convenient for reducing the electromagnetic influence of the driver on the central controller 380. Since the driver 310 is located in the duct area 130 and can use the water in the environment for heat dissipation, there is no need to set up a cooling structure for cooling the driver 310 separately, that is, there is no need to use the coolant circulation to conduct heat and dissipate heat for the driver 310 similar to the illustrated embodiment, so that the volume and weight of the propeller 1000 can be reduced to optimize the propulsion efficiency of the propeller 1000. In this embodiment, the rated power of the first motor 210 can be less than the rated power of the first motor 210 in the illustrated embodiment, so the heat dissipation demand of the driver 310 is reduced, and the layout in the duct area 130 can use the water in the external environment for heat dissipation.

[0086] In this embodiment, the electric control device 300 may further include a steering controller 330 and a tilting controller 370, which are located in the nose area 120, and are electrically connected to the central controller 380. The steering controller 330, the tilting controller 370 and the central controller 380 are separated by a partition 1102 to prevent the central controller 380 from being interfered by the signals of the steering controller 330 and the tilting controller 370. The steering controller 330, the tilting controller 370 and the central controller 380 are located in the nose area 120, and condensation cannot be formed in the nose area 120, thereby ensuring the safety of the steering controller 330, the tilting controller 370 and the central controller 380.

[0087] It is understandable that the pod area 110, the duct area 130 and the head area 120 are not absolutely airtight. The first partition element 414 is similar to the partition element 410 of the illustrated embodiment, allowing the gas to break through the sealing pressure or leak from the fine gap of the cable to the duct area 130 when the air pressure in the pod area 110 increases to a certain extent. The second partition element 415 is also similar to the partition element 410 of the illustrated embodiment, allowing the gas to break through the sealing pressure or leak from the fine gap of the cable to the head area 120 when the air pressure in the duct area 130 increases to a certain extent. The first partition element 414 and the second partition element 415 slow down the flow of a large part of the hot air to the duct area 130 and the head area 120, eliminate the formation of condensation in the duct area 130 and the head area 120, and ensure the safety of the electronic control device 300.

[0088] Further, based on Figure 6 An improvement of the illustrated embodiment, the propeller 1000 includes an upper shell 700 and a lower shell 600, the upper shell 700 is provided with a nose shell 710 and an upper duct 720 for fixing the nose shell 710, the lower shell 600 is provided with a pod shell 610 and a lower duct 620 for fixing the pod shell 610, the lower duct 620 is sealedly connected to the upper duct 720, the nose area 120 is formed in the nose shell 710, the pod area 110 is formed in the pod shell 610, a part of the duct area 130 is arranged in the upper duct 720, and another part is arranged in the lower duct 620, and the driver 310 is located in the lower duct 620.

[0089] In this embodiment, the head housing 710 and Figure 6The head shell 710 of the illustrated embodiment is substantially the same, the upper conduit 720 is substantially the same as the upper conduit 720 of the illustrated embodiment, the pod shell 610 is substantially the same as the pod shell 610 of the illustrated embodiment, and the lower conduit 620 is substantially the same as the lower conduit 620 of the illustrated embodiment, except that the outer diameters of the upper conduit 720 and the lower conduit 620 are reduced to reduce the water flow resistance, and the length of the lower conduit 620 is increased to facilitate the assembly of the driver 310 in the lower conduit 620. The wave suppressor 721 is arranged on the peripheral side of the lower conduit 620. Part of the lower conduit 620 extends into the upper conduit 720 to achieve a sealed fit between the lower conduit 620 and the upper conduit 720. The conduit area 130 is formed by the inner cavity of the upper conduit 720 and the inner cavity of the lower conduit 620, that is, most of the driver 310 is located in the lower conduit 620, but it is not excluded that part of the driver 310 is still located in the upper conduit 720 to fully utilize the space of the conduit area 130.

[0090] In this embodiment, the pod housing 610 is provided with an intermediate housing 611 connected to the downcomer 620 and a rear end cover 612 covering the intermediate housing 611, and the first conductive member 501 is provided with a bus connected to the driver 310 and a wiring harness connected to the first motor 210, and the connection between the wiring harness and the bus is opposite in the direction parallel to the axial direction of the first motor 210 at the rear end cover 612. The intermediate housing 611 and the downcomer 620 are integrally formed, and the inner cavity of the intermediate housing 611 and the inner cavity of the downcomer 620 form a "T"-shaped cavity. After the driver 310 is assembled into the downcomer 620, it is difficult to connect the output end 312 of the driver 310 with the first conductive member 501, so it is necessary to extend a part of the output end 312 of the driver 310 into the intermediate housing 611 and opposite to the rear end cover 612. Before the rear end cover 612 is assembled with the intermediate housing 611, the output end 312 of the driver 310 is first assembled and connected with the conductive adhesive from the rear end opening of the intermediate housing 611, and then the rear end cover 612 is assembled and sealed with the rear end opening of the intermediate housing 611. Specifically, during the connection and assembly process between the first conductive member 501 and the driver 310, the busbar and the driver 310 can be assembled first, and then the driver 310 can be installed in the lower guide tube 620, so that a part of the busbar extends into the intermediate housing 611 and is opposite to the rear end opening; then an assembly tool is used to extend from the rear end opening to assemble and connect the wiring harness connected to the first motor 210 with the busbar 540; finally, the rear end cover 612 is covered with the intermediate housing 611.

[0091] Specifically, in order to achieve the separation of the pod area 110 and the duct area 130 by the first partition element 414, the intermediate housing 611 is provided with a wiring groove 613, the busbar 540 is located in the wiring groove 613, the circumference of the first partition element 414 is sealed with the opening of the wiring groove 613 facing the rear end cover 612, and the first partition element 414 is provided with a harness hole sealed with the harness 530. A baffle 614 is provided in the pod housing 610 to be opposite to the downcomer 620, and a part of the baffle 614 extends to a position covering a part of the intermediate housing 611, so as to form a wiring groove 613 between the baffle 614 and the intermediate housing 611. The wiring groove 613 has a harness 530 opening facing the rear end cover 612, and the harness 530 opening is used for the AC harness 530 of the first conductive element to pass through and be connected to the first motor 210. The outer peripheral side wall of the first partition element 414 is sealed with the inner peripheral side wall of the wiring groove 613. The harness hole may include a plurality of harness holes, and the plurality of harness holes are respectively sealed and matched with the three-phase wires of the AC harness, so that the first partition element 414 can separate the pod area 110 from the duct area 130 .

[0092] In this embodiment, the end of the lower conduit 620 is provided with a boss 621 extending into the upper conduit 720, at least one sealing ring is provided between the outer peripheral side wall of the boss 621 and the inner peripheral side wall of the lower conduit 620, and the inner peripheral side wall of the upper conduit 720 is provided with a limiting platform 722, and the end of the boss 621 holds the second partition element 415 against the limiting platform 722. The coordination between the boss 621, the limiting platform 722 and the second partition element 415 is substantially the same as that of the illustrated embodiment and will not be described in detail herein.

[0093] Specifically, the second partition element 415 is provided with a mounting groove 1101 that matches the driver 310, and is provided with a DC line hole that communicates with the mounting groove 1101, and the second conductive member 502 includes a DC line harness that seals and matches with the DC line hole. The second partition element 415 is provided with a sealing cover plate 623, and a docking boss 624 is provided on one side of the sealing cover plate 623. The mounting groove 1101 extends from the side of the cover plate 623 away from the docking boss 624 to the inside of the docking boss 624. The peripheral side of the sealing cover plate 623 is sealed and matched with the inner wall of the upper conduit 720 through a sealing ring. The inner wall of the mounting groove 1101 is provided with a limiting protrusion, which is matched with the end of the driver 310 to limit and stabilize the driver 310. The docking boss 624 is provided with two DC line holes 6241 that penetrate the mounting groove 1101. The positive line and the negative line of the DC line harness pass through the two DC line holes respectively, and are tightly matched with the two DC line holes. The DC wire harness is connected to the end of the driver 310 extending into the mounting groove 1101 to transmit DC power to the driver 310. A signal wire hole 6242 is also provided between the two DC wire holes 6241 on the docking boss 624, and the signal wire hole is used to closely match the signal control wire connected to the driver 310.

[0094] See also Fig.12 , another embodiment is provided, with Figure 6The difference between the illustrated embodiment and the embodiment is that the partition 410 includes a heat-insulating box 413, and the electric control device 300 includes a driver 310 located in the heat-insulating box 413. The heat-insulating box 413 can isolate the external hot air from entering the interior, thereby preventing the external heated moisture from entering the heat-insulating box 413 and forming condensation when it encounters cold and contacts the driver 310, thereby ensuring the safety of the driver 310. Specifically, the heat-insulating box 413 is provided with a harness interface 414 and a cooling interface 415. The harness interface 414 is used to be sealed and connected with the current input harness and the current output harness, and the driver 310 inputs and outputs current from the harness interface 414. The cooling interface 415 is used to be sealed and connected with the liquid input pipe and the liquid output pipe, and the driver 310 inputs and outputs the cooling medium from the cooling interface 415. The harness interface 414 includes a DC line interface 4141 and an AC line interface 4142. The DC line interface 4141 and the AC line interface 4142 are respectively arranged at opposite ends of the heat-insulating box 413. The DC line interface 4141 is closely matched with the DC line of the battery, and the AC line interface 4142 is closely matched with the AC line electrically connected to the first motor 210. Both the DC line and the AC line are connected to the driver 310. A signal line input interface is also provided on the same side of the DC line interface 4141, and a signal line output interface is also provided on the same side of the AC line interface 4142. The signal line input interface and the signal line output interface are respectively used to connect the first signal line and the second signal line to the driver 310, the first signal line is connected to the central controller 380 and the interactive control device, and the second signal line is connected to the first motor 210. The cooling interface 415 is arranged on the same side as the AC line interface 4142. The cooling interface 415 includes a coolant input port and a coolant output port. The coolant input port and the coolant output port are closely matched with two pipes respectively. Both pipes are sealed and docked with the cooling plate of the driver 310 to input coolant into the cooling plate. The coolant absorbs the heat of the driver 310 through the cooling plate. The two pipes then use the coolant to bring the heat of the driver 310 to the cooling chamber of the embodiment shown in the figure to exchange heat with the water in the external environment to achieve cooling of the driver 310. The heat insulation box 413 can isolate moisture from condensation and contact with the driver 310 without affecting the normal operation of the driver 310, thereby ensuring the safety of the driver 310.

[0095] It is understandable that there is a heat insulating medium between the inner wall of the heat insulating box 413 and the driver 310, and the heat insulating medium may be air, which is used to isolate the heat from being conducted to the driver 310, so as to prevent the driver 310 from being heated up. Of course, in other embodiments, the heat insulating box 413 may be evacuated to a vacuum, so that no medium conducts heat to the driver 310, and the heat of the driver 310 can be dissipated to the outside through the coolant.

[0096] In some possible embodiments, the partition 410 may also include a heat-insulating box 413 for insulating the lift controller 370 and the steering controller 330. The heat-insulating box 413 wraps the lift controller 370 and the steering controller 330 to prevent external condensation from contacting the lift controller 370 and the steering controller 330, and also prevents condensation from forming inside the heat-insulating box 413 from contacting the lift controller 370 and the steering controller 330.

[0097] See also Fig.13 , another embodiment is provided, which is substantially the same as the illustrated embodiment, except that the condensation elimination structure 400 includes a condensation collection component 420, which is used to collect condensation formed by condensation of water vapor heated by the heat source 200 on the heat dissipation inner wall of the receiving cavity 100, and separate it from the electronic control device 300. The way in which the condensation collection component 420 eliminates condensation is different from the way in which the separation component eliminates condensation. The condensation collection component 420 is intended to collect condensation after it is formed in the receiving cavity 100 and guide it to a safe area to prevent condensation from contacting the electronic control device 300.

[0098] like Fig.13As shown, as a possible embodiment, the inner wall of the receiving chamber 100 has a low-temperature cooling zone 190, the temperature of the low-temperature cooling zone 190 is the lowest temperature in the receiving chamber 100, and there is a safe distance between the cooling zone 190 and the electronic control device 300. The heat dissipation inner wall is arranged in the cooling zone 190, and the condensation collection component 420 is arranged in the low-temperature cooling zone 190 to collect the condensation in the cooling zone 190. The cooling zone 190 can be provided with a strong heat dissipation structure, and the heat dissipation efficiency can be increased by using the strong heat dissipation structure, so that the temperature of this area is kept at the lowest temperature in the entire receiving chamber 100, and once the moisture in the receiving chamber 100 is heated, it will always condense in the cooling zone 190 first to form condensation. Since the moisture in the receiving chamber 100 first forms condensation in the cooling zone, the amount of moisture in the receiving chamber 100 will be reduced and it is not easy to form condensation in other areas when it encounters cold. By setting the cooling zone 190 to maintain a certain safe distance from the electronic control device 300, the condensation in the cooling zone 190 can be prevented from contacting the electronic control device 300, and the condensation collection component 420 can collect the condensation in the cooling zone 190 to prevent the condensation in the cooling zone 190 from forming saturation and then forming condensation in other locations. The condensation collection component 420 can collect condensation by drainage collection, moisture absorption collection, or scraping collection, and the condensation collection component 420 is intended to collect condensation hanging on the wall of the cooling zone 190 and guide it to a safe area. As a possible implementation, the safe area can be located at the lowest point of the receiving chamber 100, for example, a water tank is set at the lowest point of the receiving chamber 100, and the accumulated condensation is collected by the water tank. The lowest point of the receiving chamber 100 is set away from the heat source 200, and the water in the water tank does not affect the operation of the heat source 200. When the propeller 1000 stops working, the water in the water tank can be exposed to the water surface because the lowest part of the receiving chamber 100 is lifted up by the propeller 1000, so that the water in the water tank is gradually heated and evaporates to the outside of the receiving chamber 100. Of course, the safe area can also be located at the position where the receiving chamber 100 is located on the water surface, so as to quickly discharge the collected condensation out of the receiving chamber 100.

[0099] As a possible embodiment, the receiving chamber 100 is a sealed chamber, and the receiving chamber 100 has a pod area 110 located in the underwater part of the propeller 1000 and a head area 120 located in the above-water part, and a duct area 130 connecting the pod area 110 and the head area 120, the heat source 200 is located in the pod area 110, the electric control device 300 is located in the head area 120, and the cooling area 190 is located in the duct area 130 away from the head area 120. The cooling area 190 is arranged in the duct area 130, which can prevent condensation in the cooling area 190 from flowing upward to the electric control device 300 in the head area 120, and reduce the possibility of condensation in the cooling area 190 contacting the electric control device 300. The cooling zone 190 is arranged in the duct area 130 and can make full use of the fact that the duct area 130 is easily in contact with external water and will not be affected by the high temperature of the heat source 200 in the pod area 110, thereby accelerating the efficiency of condensation formation in the cooling zone 190, thereby greatly reducing the formation of condensation in other locations.

[0100] As a possible implementation, the propeller 1000 is provided with a water cooling structure 180 for cooling the cooling zone 190 outside the conduit region 130, and the water cooling structure 180 exchanges heat with external water. The water cooling structure 180 includes a plurality of heat conducting fins 181 arranged around the conduit 1400, and the heat conducting fins 181 can increase the contact area between the position of the lower conduit 620 corresponding to the cooling zone 190 and the external water, and accelerate the flow rate of water flowing between two adjacent heat conducting fins 181, thereby increasing the heat dissipation efficiency and making the temperature of the cooling zone 190 lower.

[0101] Provide an embodiment, such as Fig.14 As shown, Fig.12The implementation shown is substantially the same, except that the cooling zone 190 is located in the nose region 120. Specifically, the receiving chamber 100 is a sealed chamber, and the receiving chamber 100 has a pod region 110 located in the underwater part of the propeller 1000 and a nose region 120 located in the above-water part, and a duct region 130 connecting the pod region 110 and the nose region 120, the heat source 200 is located in the pod region 110, the electric control device 300 is located in the duct region 130, and the cooling zone 190 is located in the nose region 120 away from the duct region 130. The cooling zone 190 in the nose region 120 can utilize the rapid heat exchange between the nose region 120 and the outside airflow to achieve rapid cooling of the cooling zone 190, and the condensation collection assembly 420 is also located in the nose region 120, so as to facilitate the rapid discharge of the collected condensation from the nose 1300 out of the receiving chamber 100. Specifically, the propeller 1000 is provided with an air-cooling structure 170 for cooling the cooling zone 190 outside the head region 120, and the air-cooling structure 170 exchanges heat with the external air. The air-cooling structure 170 includes at least two groups of heat dissipation fins 171, and the two groups of heat dissipation fins 171 are respectively formed on the two side surfaces of the head housing 710 parallel to the axial direction of the first motor 210. Both groups of heat dissipation fins 171 include a plurality of strip fins arranged side by side, and the length direction of the strip fins is parallel to the axial direction of the first motor 210. The heat dissipation fins 171 are denser and more numerous than the fins in the illustrated embodiment, so as to increase the heat exchange efficiency between the airflow and the head housing 710, thereby quickly reducing the temperature on both sides of the head housing 710 to achieve a lower temperature in the cooling zone 190.

[0102] Please also read Fig.12 and Fig.15 As a possible embodiment, the condensation collection component 420 includes a cooling device 421 and a collecting device 422. The cooling device 421 cools the cooling zone 190, and the collecting device 422 collects the condensation formed in the cooling device 421 and the cooling zone 190, and drains the condensation away from the electronic control device 300. The cooling device 421 can accelerate the heat dissipation of the cooling zone 190, so that the cooling zone 190 is cooled faster and the temperature is lower. The collecting device 422 is connected to the cooling device 421, which can accelerate the collection and removal of condensation and prevent the condensation from contacting the electronic control device 300.

[0103] For example, based on Fig.12 A possible implementation method of an improvement of the embodiment shown is as follows: Fig.15As shown, the cooling device 421 includes a condensing element 4211, a compression element 4212 and an evaporation element 4213, wherein the condensing element 4211, the compression element 4212 and the evaporation element 4213 are connected to each other through a pipeline, and the evaporation element 4213 is located in the cooling zone 190 to absorb heat and refrigerate, and the compression element 4212 compresses and conducts the cooling medium conducted from the evaporation element 4213 to the condensing element 4211, and the condensing element 4211 conducts the heat of the cooling medium out of the receiving chamber 100. The condensing element 4211, the compression element 4212 and the evaporation element 4213 can all be supplied with electric current to realize the control of the phase conversion of the cooling medium. The evaporation element 4213 can be located in the conduit area 130, and the condensation element 4211 is located outside the conduit 1400. The condensation element 4211 finally dissipates the heat through the external water, thereby reducing the temperature of the evaporation element 4213, and condensation will be formed on the inner wall of the receiving chamber 100 of the evaporation element 4213 and its surroundings. The evaporation element 4213 and its surroundings may be provided with a vertically extending drainage sheet. When condensation is formed on the vertically extending drainage sheet 4214, it will flow downward to the bottom due to gravity. The collection device 422 may include a drainage housing 4221 located at the evaporation element 4213 and its vicinity. The drainage housing 4221 is provided with a drainage groove, and the drainage groove receives the condensation flowing down from the drainage sheet 4214. The collection device 422 also includes a storage housing 4222 connected to the drainage housing 4221. The storage housing 4222 is provided with a water tank. The water tank may be a structure such as the illustrated embodiment. Of course, a strong water-absorbing material such as a sponge or a desiccant may also be provided in the water tank to stabilize the collected condensation. Of course, a one-way valve may also be provided between the storage housing 4222 and the outside of the propeller 1000. The one-way valve only allows the water in the water tank to be discharged to the outside of the receiving chamber 100, but prohibits the water outside the receiving chamber 100 from entering the receiving chamber 100 through the valve.

[0104] Please also read Fig.12 and Fig.16 , as a possible implementation, with Fig.15The embodiments shown are substantially the same, except that the cooling device 421 includes a heat absorbing member 4215, the heat absorbing member 4215 is provided with a heat absorbing plate 4216 attached to the cooling zone 190, and a plurality of heat absorbing fins 4217 extending from the heat absorbing plate 4216, the heat absorbing fins 4217 absorb the heat of the cooling zone 190, and conduct the heat from the cooling zone 190 to the outside of the receiving cavity 100 through the heat absorbing plate 4216. The heat absorbing fins 4217 and the heat absorbing plate 4216 are integrally formed, and the heat absorbing fins 4217 and the heat absorbing plate 4216 can be made of metal with fast heat conduction, for example, the heat absorbing fins 4217 and the heat absorbing plate 4216 can be made of copper. The heat absorbing fins 4217 and the heat absorbing plate 4216 quickly absorb the heat of the cooling zone 190, and quickly conduct the heat to the conduit 1400, so that the conduit 1400 can quickly dissipate the heat to the water in the external environment.

[0105] like Fig.17 As shown, a different Fig.12 In the embodiment of the embodiment shown in FIG. 1 , the condensation collection assembly 420 includes a moisture-absorbing sheet 423, which is attached to the inner wall of the receiving cavity 100 and is used to absorb condensation formed on the inner wall of the receiving cavity 100. The condensation collection assembly 420 may include a plurality of moisture-absorbing sheets 423, which may be partially attached to the inner wall of the head region 120 near the driver 310, or partially attached to the head region 120 near the tilting controller 370 and the steering controller 330, or attached to a position near the central controller 380. The moisture-absorbing sheet 423 has a high condensation absorption performance by providing a water-absorbing material. When fine condensation is formed on the inner wall to which the moisture-absorbing sheet 423 is attached, the moisture-absorbing sheet 423 preferentially absorbs the condensation and stabilizes the condensation in the moisture-absorbing sheet 423, and is not easy to contact the electronic control device 300. By setting the desiccant sheet 423 to be separated from the driver 310, the lift controller 370, the steering controller 330 and the central controller 380 at a certain distance, condensation in the desiccant sheet 423 can be prevented from contacting the driver 310, the lift controller 370, the steering controller 330 and the central controller 380.

[0106] See also Fig.18 The present application also provides an embodiment, Fig.17 The embodiments shown are substantially the same, except that the condensation collection assembly 420 includes a moisture absorption assembly 424, which is disposed on one side of the valve 1200 and is used to absorb moisture on the air intake path of the valve 1200. The moisture absorption assembly 424 absorbs moisture on the air intake path of the valve 1200, thereby effectively reducing the moisture in the gas inhaled into the receiving chamber 100, that is, reducing the humidity in the receiving chamber 100, thereby reducing the formation of condensation in the receiving chamber 100.

[0107] Specifically, the moisture absorption component 424 includes a fixed cover 4241 and a multi-layer moisture absorption layer 4242 disposed in the fixed cover 4241. The fixed cover 4241 covers the air inhalation path of the valve 1200. The multi-layer moisture absorption layer 4242 is arranged along the air inhalation path of the valve 1200. The fixed cover 4241 is provided with a drainage groove 4243 for guiding the liquid absorbed by the multi-layer moisture absorption layer 4242 to a safe area. In a possible implementation, the fixed cover 4241 is located outside the valve 1200. The fixed cover 4241 is provided with an inner air port and an outer air port, and a bent air passage 4244 located between the inner air port and the outer air port. The inner air port is connected to the valve 1200, and the outer air port is provided outside the fixed cover 4241. The multi-layer hygroscopic layer 4242 is disposed in the bent air passage 4244. When the valve 1200 inhales air from the outer air port, the external air passes through the outer air port, the multi-layer hygroscopic layer 4242 and the inner air port in sequence, so that the multi-layer hygroscopic layer 4242 can absorb moisture in the air, thereby reducing the moisture in the air passing through the valve 1200. The fixed cover 4241 is provided with a drainage groove 4243 at the bottom of the bent air passage 4244. The drainage groove 4243 has an opening facing the outer side of the fixed cover 4241, so that the moisture absorbed by the multi-layer hygroscopic layer 4242 is collected and guided to the outer side of the valve 1200, thereby preventing water from entering the receiving chamber 100.

[0108] See also Fig.17 The present application also provides an embodiment, Fig.12 The embodiment shown is substantially the same, except that the condensation elimination structure 400 includes an anti-condensation coating, and the anti-condensation coating 430 is arranged on the surface of the electric control device 300 to prevent the water molecules on the surface of the electric control device 300 from gathering to form condensation. The anti-condensation coating 430 is coated on the surface of the electric control device 300, so that the surface of the electric control device 300 is hydrophobic, so that condensation is not easily formed on the surface of the electric control device 300, and the electric control device 300 is not easily in contact with condensation to cause the risk of short circuit. As a possible implementation method, the anti-condensation coating 430 is a nano-technology coating, which increases the surface hydrophobicity of the electric control device 300, thereby further reducing the formation of condensation on the surface of the electric control device 300.

[0109] See also Fig.19 The present application also provides an embodiment, Fig.17The illustrated embodiments are substantially the same, except that the condensation elimination structure 400 includes a heat insulation module 440, which is used to prevent the heat of the heat source 200 from being transferred to the area around the electric control device 300, so as to reduce the temperature rise of water vapor around the electric control device 300. The heat insulation module 440 is different from the partition 410 of the illustrated embodiment. The heat insulation module 440 can block the heat conduction of the heat source 200 but does not prevent the flow of gas. The heat insulation module 440 blocks most of the heat in the area where the heat source 200 is located, thereby preventing the heat from being transferred to the area where the electric control device 300 is located, and preventing the moisture in the area where the electric control device 300 is located from forming condensation after being heated and then cooled. As a possible implementation, for example, the heat source 200 includes a first motor 210, which is used to drive the propeller 220 to rotate, the receiving chamber 100 includes a pod area 110 located at the underwater part of the propeller 1000 and a head area 120 located at the above-water part of the propeller 1000, and a duct area 130 connecting the pod area 110 and the head area 120, the first motor 210 is located in the pod area 110, the electric control device 300 is located in the head area 120 or / and the duct area 130, and the heat insulation module 440 is located in the pod area 110 to prevent the temperature rise of the pod area 110 from being conducted to the duct area 130 and the head area 120. Specifically, the heat insulation module 440 includes a heat insulation coating, which is arranged on the inner wall of the pod area 110. The heat insulation coating is disposed near the inner wall where the pod area 110 is connected to the conduit area 130, so that when the heat in the pod area 110 is conducted to the conduit area 130, the heat insulation coating can block the conduction of heat, thereby slowing down the temperature rise of the pod area 110, thereby reducing the formation of condensation in the conduit area 130. In another embodiment, the heat insulation module 440 includes a heat insulation member, which is disposed at the place where the pod area 110 is connected to the conduit area 130. The heat insulation member can be bonded to the inner wall where the pod area 110 is connected to the conduit area 130. The heat insulation member can be a heat insulation foam, or a heat insulation rubber, or a heat insulation film layer.

[0110] See also Fig. 20 The present application also provides an embodiment, Fig.10The embodiments shown are substantially the same, except that the condensation elimination structure 400 includes an airtight component 450, which is arranged at the assembly gap of the above-water part of the propeller 1000 to prevent external gas from entering the receiving chamber 100 from the assembly gap. The condensation elimination structure 400 prevents gas from entering the receiving chamber 100 from the assembly gap, which means that the condensation elimination structure 400 is intended to reduce moisture in the receiving chamber 100 and reduce the formation of condensation by reducing the gas entering from the assembly gap. The airtight component 450 can be arranged in the assembly gap or outside the assembly gap, and is located on the inside or outside of the receiving chamber 100. It can be understood that the assembly gap is located in the above-water part of the propeller 1000 to prevent water from entering the receiving chamber 100 from the assembly gap. The assembly gap is formed between components with large thermal expansion and contraction deformation, that is, the assembly gap is usually caused by the thermal expansion and contraction of the component, which increases the gap caused by the external gas entering the receiving chamber 100 from the assembly gap. The airtight component 450 can adapt to the gap change caused by thermal expansion and contraction, thereby enhancing the airtightness and preventing gas from entering the receiving cavity 100 .

[0111] For example, Fig. 20 and Fig.21As shown, as a possible implementation, the thruster 1000 includes a cable harness 900 electrically connected to the electric control device 300, the assembly gap is formed in the cables inside the cable harness 900, and one end of the cable harness 900 away from the electric control device 300 is located outside the receiving cavity 100. One end of the cable harness 900 is connected to the power battery outside the receiving cavity 100, and the other end is connected to the driver 310 inside the receiving cavity 100. The cable harness 900 is also connected to the interactive control device located outside the receiving cavity 100, and is connected to the central controller 380 in the receiving cavity 100. Therefore, the cable harness 900 includes a plurality of cables 910. Although each cable 910 can be sealed with the head shell 710 individually, each cable 910 is only sealed with the head shell 710 by the external insulating packaging material 911. A plurality of conductive metal wires 912 are spliced ​​together in the insulating packaging material 911. Since the cross section of each conductive metal wire 912 is circular, there exists a gap between adjacent conductive metal wires 912, which is the assembly gap of the cable harness 910 bundle 900. When the conductive metal wire 912 transmits a large current, it is easy to heat up and cause its diameter to increase, thereby causing the insulating packaging material 911 to expand. At this time, the assembly gap will also increase accordingly, which is easy to cause gas to enter the receiving cavity 100 from the assembly gap. In order to prevent the transmission of external gas into the receiving chamber 100 through the assembly gap, the airtight component 450 includes an elastic element 451, which is arranged in the assembly gap. The elastic element 451 produces elastic deformation as the cables of the cable bundle 910 900 expand and contract due to heat, and the elastic element 451 blocks the assembly gap. When the diameter of the conductive metal wire 912 increases due to heat, the elastic element 451 will also expand due to heat and fill the gaps between the multiple conductive metal wires 912, thereby blocking the gas transmission in the assembly gap. It can be understood that the airtight component 450 is an insulating material to provide good protection for the conductive wires.

[0112] Furthermore, the airtight assembly 450 further includes a stabilizing member 452, which tightens the circumference of the cable harness 900 to limit the expansion of the cable harness 900. The stabilizing member 452 is a metal hoop, which is hooped around the circumference of the cable 910, thereby limiting the expansion of the insulating package 911 of the cable 910, thereby preventing the expansion of the assembly gap. When the conductive metal wire 912 expands due to heat, the assembly gap will be limited by the stabilizing member 452 and reduced, and the contact between the airtight assembly 450 and the conductive metal wire 912 will be closer, further increasing the airtightness, thereby improving the condensation elimination efficiency in the receiving cavity 100 and ensuring the safety of the electronic control device 300.

[0113] See also Fig. 22 The present application also provides an embodiment, Figure 4The embodiments shown are substantially the same, except that the propeller 1000 cancels the valve 1200 setting, that is, the receiving chamber 100 does not need to breathe gas through the valve 1200 to achieve a stable internal air pressure, so that the receiving chamber 100 can be combined with the airtight component 450 to make the receiving chamber 100 almost completely airtight. In this embodiment, the condensation elimination structure 400 also includes a pressure relief device 460, which is connected to the receiving chamber 100 and is used to release the air pressure in the receiving chamber 100. When the heat source 200 heats the gas in the receiving chamber 100, the air pressure in the receiving chamber 100 increases, and the pressure relief device 460 can release the increased air pressure, thereby maintaining the internal air pressure of the receiving chamber 100 stable. Provide a possible implementation, as shown in the figure, the pressure relief device 460 includes a deformable airbag 461, which is connected to the receiving chamber 100, and absorbs the gas in the receiving chamber 100 when the air pressure in the receiving chamber 100 increases. Specifically, the receiving chamber 100 has an interface for connecting the deformable airbag 461, and the interface is located at the top of the receiving chamber 100. When the temperature rise of the heat source 200 in the receiving chamber 100 increases and the air pressure increases, the deformable airbag 461 begins to inhale and expand, thereby releasing the increased air pressure in the receiving chamber 100. Of course, in another embodiment, the deformable airbag 461 can also be replaced with a pressure relief chamber and a piston that can move elastically in the pressure relief chamber. When the air pressure in the receiving chamber 100 increases, the gas enters the pressure relief chamber and forces the piston to move, thereby increasing the gas holding space of the pressure relief chamber. When the air pressure in the receiving chamber 100 returns to normal, the elastic piston returns to its original position under the elastic force, and the normal air pressure in the receiving chamber 100 is restored.

[0117] Furthermore, as shown in the figure, the movable device 3000 in the water area further includes an interactive system 3100, which is arranged on the hull 2000 and is used to receive instructions and control the operation of the propeller 1000.

[0118] Specifically, the interactive system 3100 includes a steering wheel, a button, and a shift device. The steering wheel is rotatably arranged on the hull 2000, and is used to receive a user's steering control signal, and convert the steering control signal into a steering electrical signal, and the steering electrical signal is transmitted to the steering motor via a conductive cable, thereby controlling the steering of the hull 2000. The button is installed at the bow of the hull 2000, and can be located on one side of the steering wheel, and is used to receive a user's tilting command to control the operation of the tilting structure, so that the pod shell 610 and the propeller 220 of the propeller 1000 are tilted, or the pod shell 610 and the propeller 220 are controlled to sink underwater. The shift device is installed on the hull 2000, and is electrically connected to the driver 310 via a conductive cable, and is used to receive the user's forward and backward control commands, and transmit the forward and backward control commands to the driver 310 to control the operation of the first motor 210. The interactive system 3100 also includes a display screen, which is used to receive a user's touch command and transmit the user's touch command to the propeller 1000. The central controller 380 converts the operation information of the propeller 1000 into information that can be displayed on the display screen, so that the user can obtain the operation status of the propeller 1000. It can be understood that the interactive system 3100 of the present application is not limited to the above-mentioned embodiments, and any interactive system 3100 that is intended to enable the user to control and interact with the propeller 1000 can be used as an implementation method of the text application.
