[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0024] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-Figure 6 As shown, an embodiment of the present application discloses a photoelectric turntable, which includes a bracket assembly 11, a detection chamber 21, a detection assembly, a heating and deicing assembly 30 and a cable 40.

[0026] Among them, the detection chamber 21 is rotatably connected to the bracket assembly 11, so that the detection chamber 21 can change its orientation and angle to obtain scenes at different positions around the photoelectric turntable. The detection assembly is installed in the detection chamber 21, which is a device in the photoelectric turntable specifically used to obtain scenes. The heating and deicing assembly 30 is installed in the bracket assembly 11, and the heating and deicing assembly 30 is located at the rotation gap between the detection chamber 21 and the bracket assembly 11, and the heating and deicing assembly 30 can generate heat when powered on, so that after ice occurs in the gap between the detection chamber 21 and the bracket assembly 11, the ice is removed by heating, and the gap between the detection chamber 21 and the bracket assembly 11 can be prevented from re-freezing to a certain extent. The cable 40 is a device for powering the heating and deicing assembly 30, and one end of the cable 40 is connected to a device such as a circuit board in the photoelectric turntable, and the other end is electrically connected to the heating and deicing assembly 30. The parameters such as the diameter and material of the cable 40 can be flexibly selected according to actual conditions, and this article does not limit this.

[0027] The photoelectric turntable detects the corresponding parameters of the environment or the target through the detection component. Optionally, the detection component includes one or more of a visible light camera 22, an infrared detection device 23, a thermal imaging camera, a laser lighting device, and a laser ranging device. The detection component is arranged in the detection chamber 21, and the detection chamber 21 is provided with a detection port corresponding to the detection component and a light-transmitting member installed at the detection port. The detection component detects the external environment through the light-transmitting member to obtain the corresponding parameters. The detection component is fixedly connected to the detection chamber 21 so that the detection component moves synchronously with the movement of the detection chamber 21.

[0028] The detection chamber 21 can rotate relative to the bracket assembly 11 to adjust the detection direction of the detection assembly. The detection chamber 21 partially protrudes to form a shaft-like structure, and the shaft-like protrusion passes through the heating and deicing assembly 30 and is rotatably connected to the bracket assembly 11. The heating and deicing assembly 30 is fixedly installed on the bracket assembly 11 and is located in the gap where the detection chamber 21 rotates relative to the bracket assembly 11, wherein the detection chamber 21 can rotate relative to the heating and deicing assembly 30. For example, the detection chamber 21 is provided with a rotating shaft, and the heating and deicing assembly 30 is provided with an avoidance hole, and the rotating shaft passes through the avoidance hole and is rotatably connected to the bracket assembly 11, so that the detection chamber 21 can rotate relative to the bracket assembly 11.

[0029] There is a rotation gap between the detection chamber 21 and the heating and deicing assembly 30, and the heating and deicing assembly 30 is heated when powered on. The heat emitted by the heating and deicing assembly 30 can directionally melt the ice at the rotation gap between the detection chamber 21 and the bracket assembly 11. The detection chamber 21 can rotate relative to the bracket assembly 11 and adjust the detection direction of the detection assembly, and has good rotation flexibility. The heat generated by the heating and deicing assembly 30 is mainly concentrated in the rotation gap, and the required heating area and heat dissipation space are small, which reduces the power and energy required for the heating and deicing assembly 30 and reduces power consumption. The rotation gap between the detection chamber 21 and the heating and deicing assembly 30 is small. After the heating and deicing assembly 30 completes the deicing step, the insulation function can be performed, and the required heating power is further reduced.

[0030] like Figure 3 and Figure 4As shown, in one embodiment, the heating and deicing assembly 30 includes a radiation plate 31 and a heat source 32 fixed to the radiation plate 31. The radiation plate 31 can be detachably assembled on the bracket assembly 11, and the radiation plate 31 radiates the heat emitted by the heat source 32. The radiation plate 31 is made of a metal material with high thermal conductivity, so that the heat emitted by at least one heat source 32 can be transferred to the entire radiation plate 31, thereby expanding the deicing range of the heating and deicing assembly 30. For example, the radiation plate 31 is made of aluminum or aluminum alloy material and processed by a sheet metal stamping process. The radiation plate 31 is installed on the bracket assembly 11 and strengthens the function of the bracket assembly 11, quickly transferring the heat of the heat source 32 to the entire area of ​​the radiation plate 31, and radiating heat to the peripheral rotating mechanism matching gap and the cavity space of the bracket assembly 11. The radiation plate 31 directly heats the icing problem area of ​​the photoelectric turntable, which can effectively control heat loss and improve deicing efficiency.

[0031] At least one heat source 32 is fixed to the radiation plate 31, and the two are tightly combined, which can reduce the thermal resistance between the heat source 32 and the radiation plate 31, effectively improve the efficiency of heat transfer and reduce losses. The heat source 32 is configured as an electrical component that converts electrical energy into thermal energy. Optionally, the heat source 32 is configured as a heating tube or an infrared heating radiator. Among them, the heating tube includes a shell made of a metal tube material, a spiral electric heating alloy wire evenly distributed along the central axis of the shell, and an insulating seal enclosed at the end of the shell to improve the sealing of the heat source 32, wherein the gap between the shell and the spiral electric heating alloy wire is filled and compacted with magnesium oxide sand with good insulation and thermal conductivity. Optionally, the radiation plate 31 encloses the heating tube in the bracket assembly 11. Among them, the infrared rays emitted by the infrared heating radiator can heat the ice layer between the bracket assembly 11 and the detection chamber 21, so that the ice layer is heated and melted.

[0032] In an optional embodiment, the heat source element 32 is bent and distributed along the surface of the radiation plate 31 and connected to the radiation plate 31, so that the contact area between the heat source element 32 and the radiation plate 31 is increased. For example, the outer shell of the heating tube is welded to the radiation plate 31, and can be processed by full welding or segment welding. The input voltage and power density of the heating and deicing assembly 30 can be freely combined with the power supply and the supporting circuit, and various electrical properties such as surface insulation, voltage resistance, and breakdown resistance can be designed according to different technical requirements. Optionally, the heating and deicing assembly 30 contacts the ice layer through the radiation plate 31, and the heating tube is arranged in the bracket assembly 11, avoiding the addition of additional protective structures such as waterproof and anti-leakage, and can quickly and efficiently meet the deicing requirements, ensuring the free rotation function of the photoelectric turntable in various low-temperature harsh environments.

[0033] The heat source element 32 is bent into a bent tube structure to expand the heating area of ​​the heat source element 32. For example, the heat source element 32 is bent to be approximately in a "U" or "Z" shape; or, the heat source element 32 is in a continuous bending structure; or, the heat source element 32 includes a curved first bending portion, a second bending portion, and a connecting portion connecting the first bending portion and the second bending portion, wherein the first bending portion and the second bending portion are approximately in a "C" shape, or, the first bending portion and the second bending portion are approximately in a concentric arc structure, and of course, the first bending portion and / or the second bending portion can be partially bent to adapt to the installation requirements of the radiation plate 31.

[0034] In one embodiment, the radiation plate 31 is provided with an avoidance portion 311, and the heat source element 32 is bent and distributed along the surface of the radiation plate 31 and is bent to avoid the avoidance portion 311. The avoidance portion 311 is arranged to avoid the notch or hole-shaped structure of the detection chamber 21 and the bracket assembly 11, and the heat source element 32 is bent to avoid the avoidance portion 311 and expand the contact area between the heat source element 32 and the radiation plate 31. The heat radiated by the radiation plate 31 can effectively cover the inner cavity and the rotation gap of the photoelectric turntable, meeting the demand for rapid deicing of the whole machine in a low-temperature environment.

[0035] In an optional embodiment, two or more heat source elements 32 are provided, and the two or more heat source elements 32 are symmetrically distributed on the radiation plate 31. The heat source elements 32 are symmetrically arranged on the radiation plate 31, shortening the total length of a single heat source element 32 and reducing the cost of the heat source element 32. Under the heating of the heat source element 32, the radiation plate 31 makes the heat source evenly distributed, the melting efficiency of the condensed ice layer is high, and the balance of ice melting is good. For example, the avoidance portion 311 includes a circular hole area that passes through the radiation plate 31, and the two heat source elements 32 are bent and symmetrically distributed on the radiation plate 31 and surround the avoidance area. Alternatively, the avoidance portion 311 includes an avoidance gap opened to the edge of the radiation plate 31, and the two heat source elements 32 are symmetrically distributed on both sides of the avoidance gap.

[0036] In one embodiment, the support assembly 11 includes a pitch support, a pitch drive device installed on the pitch support, and a torque test device, and the heating and deicing assembly 30 is fixedly connected to the pitch support. The detection chamber 21 is connected to the pitch drive device, and the torque test device is used to detect the torque when the pitch drive device drives the detection chamber 21 to rotate. When the torque parameter of the torque test device is greater than the standard value, the heating and deicing assembly 30 is powered on to generate heat.

[0037] The pitch drive device is installed in the pitch bracket and connected to the detection chamber 21, so that the detection chamber 21 is connected to the pitch bracket and can rotate relative to the pitch bracket. Among them, the pitch drive device drives the detection chamber 21 to rotate relative to the pitch bracket according to the control signal to adjust the detection direction and angle of the detection component. The torque testing device is connected to the pitch drive device and the rotating shaft of the detection chamber 21, so that the torque force driven by the pitch drive device to rotate the detection chamber 21 can be detected by the torque testing device. When there is no ice or the amount of ice between the detection chamber 21 and the heating and deicing assembly 30 is small, the torque testing device detects that the torque force driven by the pitch drive device to rotate the detection chamber 21 is a first torque value, and the first torque value is within the standard value range of the normal operation of the photoelectric turntable, then the heating and deicing assembly 30 is not powered on to generate heat. When ice condenses in the rotation gap between the detection chamber 21 and the heating and deicing assembly 30, the torque testing device detects that the torque parameter of the pitch driving device driving the detection chamber 21 to rotate is a second torque value, and the second torque value exceeds the standard value range of the normal operation of the photoelectric turntable, then the heating and deicing assembly 30 is powered on and heated. The heating and deicing assembly 30 is powered on and heated or is in a dormant state according to the detection result of the torque testing device to save energy.

[0038] In addition to the torque testing device for detection, the power-on trigger mechanism of the heating and deicing assembly 30 may also use other detection methods. For example, the ambient temperature is detected as the power-on trigger mechanism of the heating and deicing assembly 30; the distance of the rotation gap between the detection chamber 21 and the bracket assembly 11 is detected by infrared sensing or other methods as the power-on trigger mechanism of the heating and deicing assembly 30. In an optional embodiment, the photoelectric turntable also includes a temperature detection device for detecting the ambient temperature; when the ambient temperature is less than or equal to zero degrees, the heating and deicing assembly 30 is powered on to generate heat. The temperature detection device may be a temperature detection device installed on the surface of the bracket assembly 11, such as a temperature detection device configured as a temperature sensor. When the ambient temperature is less than zero degrees, water easily condenses into ice at the rotation gap. The heating and deicing assembly 30 is heated or kept warm when the ambient temperature reaches zero degrees to maintain the rotation stability of the detection chamber 21.

[0039] When the photoelectric turntable cannot rotate due to ice, the heating and deicing assembly 30 is started to convert electrical energy into thermal energy. The ice layer condensed in the rotating gap is converted into liquid water under the action of the thermal energy of the heating and deicing assembly 30. The heat of the heating and deicing assembly 30 is transferred to the ice layer in two ways: (1) The heat source 32 itself heats the ice layer by radiation heat dissipation, which is mainly concentrated in the middle and upper part of the rotating gap, with hot air flowing upward and water flowing downward. (2) After the middle and upper ice layer melts, the ice-water mixture will gather again at the bottom of the pitch bracket. The heat generated by the heat source 32 heats the entire fan-shaped radiation plate 31 by heat conduction, so that the temperature of the middle and lower ice layer reaches above the freezing point, thereby ensuring the deicing effect of the whole machine.

[0040] After the heating and deicing component 30 is started for a period of time, the rotation time of the turntable in each direction is tested through the sensor inside the product. When the operation of the photoelectric turntable reaches the set value, the heating and deicing component 30 is turned off or enters the insulation mode. Optionally, the heating and deicing component 30 is set with a heating mode and a insulation mode. In the heating mode, its power is relatively large and the heating temperature is high, so that the ice in the rotating gap can melt quickly. When the heating and deicing component 30 enters the insulation mode after heating for a preset period of time, its power is relatively small, so that the water flowing into the rotating gap will not condense into ice, and the power consumption of the photoelectric turntable can be reduced to a certain extent, and the energy-saving effect is good.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment, the pitch support in the support assembly 11 includes a support body 111, a first support arm 112 and a second support arm 113 arranged relatively to the support body 111, and the first support arm 112 and the second support are arranged at intervals, so that the detection chamber 21 can be sandwiched and installed between the first support arm 112 and the second support arm 113. In this case, a heating and deicing assembly 30 can be provided between the first support and the detection chamber 21, and between the second support arm 113 and the detection chamber 21, which can further ensure that the rotation gap on both sides of the detection chamber 21 will basically not be frozen.

[0042] The detection chamber 21 is connected to the first arm 112 and the second arm 113, and is connected to the pitch drive device so that the detection chamber 21 can rotate relative to the first arm 112 and the second arm 113. In one embodiment, the detection chamber 21 includes a chamber body and a rotation shaft fixed on opposite sides of the chamber body, and the two rotation shafts are respectively defined as a first rotation shaft and a second rotation shaft, the first rotation shaft and the second rotation shaft are coaxially arranged, and the first rotation shaft is rotatably connected to the first bracket, and the second rotation shaft is rotatably connected to the second arm 113. The pitch drive device can be connected to the first rotation shaft, and the detection assembly is installed in the chamber body. The chamber body is set as a hollow shell structure, and the detection assembly is set in the chamber body, which is easy to install. The first rotation shaft and the second rotation shaft are coaxially arranged in the chamber body. Optionally, the first rotation shaft and the second rotation shaft can be detachably connected to the chamber body so that the two are fixed to each other and the rotation position can be adjusted.

[0043] In another embodiment of the present application, both the first rotating shaft and the second rotating shaft are integrally formed with the warehouse body; or, one of the first rotating shaft and the second rotating shaft is integrally formed with the warehouse body to improve the processing efficiency of the detection warehouse 21. Optionally, the detection port is opened in the warehouse body, and the center line of the detection port is perpendicular to the axis of the first rotating shaft.

[0044] The first rotating shaft passes through the avoidance portion 311 of the heating and deicing assembly 30 and is plugged and connected to the first arm 112, and the second rotating shaft passes through the avoidance portion 311 of the heating and deicing assembly 30 and is plugged and connected to the second arm 113, so that the detection chamber 21 frame can form a reliable assembly relationship with the first arm 112 and the second arm 113. In addition, the two heating and deicing assemblies 30 located on the opposite sides of the detection chamber 21 are arranged opposite to each other and are respectively arranged opposite to the two side surfaces of the chamber body, so that the rotation gap between the detection chamber 21 and the first arm 112 (and the second arm 113) can be used to accommodate the heating and deicing assembly 30, and ensure that the rotation flexibility between the detection chamber 21 and the first arm 112 and the second arm 113 is still relatively good. The first arm 112 and the second arm 113 both include a shell, and the shell is provided with a hollow installation space, and the pitch drive device can be arranged in the shell of the first arm 112.

[0045] As described above, a heating and deicing assembly 30 may be provided between the first arm 112 and the detection chamber 21, and between the second arm 113 and the detection chamber 21, and the heating and deicing assembly 30 may include a radiation plate 31. In this case, the radiation plate 31 provided between the first arm 112 and the detection chamber 21, and between the second arm 113 and the detection chamber 21 may be a whole piece to reduce the difficulty of installing the radiation plate 31.

[0046] In another embodiment of the present application, the radiation plate 31 includes a first radiator 312 and a second radiator 313, which are separately arranged, so that the size of each of the first radiator 312 and the second radiator 313 is relatively small, which can greatly reduce the processing difficulty of the first radiator 312 and the second radiator 313. In addition, as the use time of the optoelectronic turntable increases, the cost of replacing the first radiator 312 and the second radiator 313 is also relatively low.

[0047] Specifically, taking the radiation plate 31 between the first arm 112 and the detection chamber 21 as an example, the shapes of the first radiator 312 and the second radiator 313 can be determined according to the parameters such as the specific shape of the gap between the first arm 112 and the detection chamber 21, which is not limited in this article. Of course, in order to make the compactness between the first arm 112 and the detection chamber 21 relatively better as much as possible, in the embodiment of the present application, on the plane perpendicular to the spacing direction of the first arm 112 and the second arm 113, the projections of the first radiator 312 and the second radiator 313 do not overlap each other. That is, the first radiator 312 and the second radiator 313 are each used to heat different areas on the detection chamber 21, which can also improve the thermal utilization rate.

[0048] More specifically, the structures of the first radiator 312 and the second radiator 313 can be made relatively symmetrical, which can reduce the difficulty of processing the first radiator 312 and the second radiator 313 to a certain extent, and reduce the difficulty of installing the heat source 32 on the first radiator 312 and the second radiator 313, and can also improve the heat generation uniformity of the first radiator 312 and the second radiator 313, thereby ensuring that the heating efficiency of any position in the rotation gap of the detection chamber 21 is relatively good. Similarly, the radiation plate 31 of the heating and deicing assembly 30 disposed between the second arm 113 and the detection chamber 21 can also be designed accordingly with reference to the above embodiment.

[0049] Optionally, the first arm 112 includes a first arm 112 body and a first sealing plate, the first arm 112 body is provided with a first mounting opening and a first rotation hole, and the first sealing plate is detachably mounted on the first arm 112 body and sealed at the first mounting opening. The first rotating shaft is plugged and connected to the first rotation hole, and the pitch driving device is assembled to the first rotating shaft along the first mounting opening, so that the pitch driving device is easy to assemble. Optionally, the pitch driving device is configured as a motor.

[0050] In an optional embodiment, the first arm 112 and the second arm 113 are respectively detachably connected to the bracket body 111. Specifically, the first arm 112 and the second arm 113 can be connected to the bracket body 111 by plug-in connection, fastener locking connection and other detachable methods, which is convenient to connect.

[0051] As described above, the heating and deicing assembly 30 can be powered by the cable 40, and since other components such as the detection component in the photoelectric turntable also need to be powered, one end of the cable 40 can be located in the housing of the bracket assembly 11, so as to be electrically connected to components such as the circuit board in the housing, thereby ensuring that the cable 40 can be powered normally. Accordingly, in order to ensure that the other end of the cable 40 located at one end in the housing of the bracket assembly 11 can form an electrical connection relationship with the heating and deicing assembly 30 located outside the housing of the bracket assembly 11, a through hole can be provided on the housing of the bracket assembly 11, so that the other end of the cable 40 can pass through the through hole and be electrically connected to the heating and deicing assembly 30. More specifically, the through hole can be provided in the bracket body 111 of the bracket assembly 11, so that the cable 40 of the heating and deicing assembly 30 installed at the rotation gap between the detection chamber 21 and the bracket assembly 11 can pass from the through hole into the bracket body 111.

[0052] As described above, the bracket assembly 11 may include a first arm 112 and a second arm 113, and a heating and deicing assembly 30 may be provided between the first arm 112 and the detection chamber 21, and between the second arm 113 and the detection chamber 21. In this case, through holes may be provided on the side of the first arm 112 facing the second arm 113, and on the side of the second arm 113 facing the first arm 112, and one of the cables 40 respectively connected to the two heating and deicing assemblies 30 may extend into the housing of the first arm 112, and the other may extend into the housing of the second arm 113, so as to be respectively connected to the circuit boards and other devices for power supply in the first arm 112 and the second arm 113. In addition, in the process of connecting the cable 40 and the heating and deicing assembly 30, it is necessary to form a reliable electrical connection between the power supply end of the heat source 32 of the heating and deicing assembly 30 and the wire core of the cable 40.

[0053] As described above, during the operation of the photoelectric turntable, liquid water may enter the gap between the detection chamber 21 and the bracket assembly 11, and since the heating and deicing assembly 30 is disposed between the detection chamber 21 and the bracket assembly 11, in order to prevent liquid or solid water from adhering to the connection between the heating and deicing assembly 30 and the cable 40, causing a short circuit of the heating and deicing assembly 30, during the process of connecting the cable 40 and the heating and deicing assembly 30, an insulating tape or the like may be wrapped outside the joint between the two. In another embodiment of the present application, in order to further improve the insulation reliability between the connection between the cable 40 and the heating and deicing assembly 30 and the outside world, after the cable 40 and the heating and deicing assembly 30 form a reliable connection relationship, insulating glue may be applied outside the joint between the two, and the insulating glue may be used to completely wrap the exposed wire core in the cable 40 and the electrical connection structure such as the power supply terminal of the heat source 32 of the heating and deicing assembly 30.

[0054] In addition, since the cable 40 passes through the shell of the bracket assembly 11, and the environment outside the bracket assembly 11 is relatively complex, in order to prevent external water vapor or dust from entering the bracket assembly 11 from the through hole of the shell of the bracket assembly 11, in the embodiment of the present application, the cable 40 can also be sealed and connected to the inner wall of the through hole. Specifically, the gap between the through hole and the cable 40 can be blocked by an elastic seal, etc., by setting an elastic seal on the cable 40. In another embodiment of the present application, after the cable 40 passes through the through hole, the through hole can be blocked by glue, etc., by applying glue at the gap between the cable 40 and the through hole. This can further improve the sealing reliability of the through hole, thereby maximally preventing impurities such as water vapor and dust from entering the bracket assembly 11, and thus preventing the devices in the bracket assembly 11 from being damaged.

[0055] The embodiment of the present application discloses a photoelectric turntable, wherein the detection chamber 21 is rotatably connected to the support assembly 11, and the detection chamber 21 is equipped with a detection assembly so that the detection assembly can rotate relative to the support assembly 11, thereby obtaining scenes at different positions around the photoelectric drilling platform. At the same time, a heating and deicing assembly 30 is installed at the rotation gap between the detection chamber 21 and the support assembly 11. When the heating and deicing assembly 30 is working, it can generate heat, so that the heat can be transmitted to the rotation gap between the detection chamber 21 and the support assembly 11, so that even if solid water condenses in the rotation gap, it can be melted by heating, thereby preventing the detection chamber 21 from being unable to rotate normally relative to the support assembly 11.

[0056] At the same time, in the optoelectronic turntable disclosed in the embodiment of the present application, one end of the cable 40 used to supply power to the heating and deicing assembly 30 is located inside the housing of the bracket assembly 11, so that the cable 40 can be electrically connected to components such as circuit boards used to supply power in the optoelectronic turntable, and normally supply power to the heating and deicing assembly 30. The cable 40 can pass through the through hole of the housing of the bracket assembly 11 to the outside of the bracket assembly 11 to be electrically connected to the heating and deicing assembly 30. In addition, by sealing the cable 40 with the inner wall of the through hole, impurities such as water vapor or dust outside the bracket assembly 11 can be prevented from entering the bracket assembly 11 through the gap between the through hole and the cable 40, thereby ensuring that the sealing reliability of the bracket assembly 11 is relatively good, improving the service life of the components installed in the housing of the bracket assembly 11 in the optoelectronic turntable, and thus improving the safety of the entire optoelectronic turntable.

[0057] As described above, a relatively reliable sealing fit relationship can be formed between the through hole and the cable 40 by applying glue. In order to improve the fixing effect of the cable 40 at the through hole and reduce the difficulty of installing the cable 40, in another embodiment of the present application, the optoelectronic turntable may also include a wire fixing member 50, and the wire fixing member 50 is sealed and connected to the inner wall of the through hole. Specifically, the two can form a fixed connection relationship by bonding or the like, so that the two can directly form a relatively reliable sealing fit relationship during the assembly process. In addition, in the above embodiment, the heat source member 32 can be welded and fixed to the surface of the radiation plate 31, and the radiation plate 31 can be installed on the first arm 112 (or the second arm 113). In this case, in order to improve the heating effect of the heat source member 32 on the ice in the gap on both sides of the detection chamber 21, the heat source member 31 can be located on the side of the radiation plate 31 facing the detection chamber 21. Based on this, in order to ensure that the cable 40 can form a connection relationship with the heat source member 32, optionally, as Figure 3 , Figure 4 and Figure 6As shown, a through hole 310 can be formed on the radiation plate 31, and the cable 40 can extend through the through hole 310 to the side of the radiation plate 31 facing the detection chamber 21 to connect with the heat source 32. Of course, in the process of forming the through hole 310, the shape and size of the through hole 310 can also be designed with reference to the corresponding design of the wire fixing member 50, so that a part of the wire fixing member 50 can extend into the through hole 310, so that the gap between the radiation plate 31 and the first arm 112 (or the second arm 113) is smaller, thereby improving the compactness of the components in the optoelectronic turntable disclosed in the embodiment of the present application.

[0058] In another embodiment of the present application, the wire fixing member 50 can also be sealed and connected to the inner wall of the through hole through a sealing ring 61, which provides a prerequisite for a detachable connection relationship between the wire fixing member 50 and the housing. Specifically, the wire fixing member 50 and the housing can be fixedly connected by a threaded connection, and the sealing ring 61 is sleeved outside the wire fixing member 50, so that the wire fixing member 50 can squeeze the sealing ring 61 when it is screwed into the through hole of the housing, so that the sealing ring 61 can more effectively block the gap between the wire fixing member 50 and the through hole. In another embodiment of the present application, the wire fixing member 50 and the housing can be detachably fixedly connected by multiple threaded connectors, which can reduce the design difficulty of the wire fixing member 50 and the housing, and can improve the reliability of the fixed connection relationship between the wire fixing member 50 and the housing. Specifically, a plurality of mounting holes 51 may be provided on the wire fixing member 50. The mounting holes 51 may be reamed holes or threaded holes. The threaded connectors are installed in the plurality of mounting holes 51 one by one and connected to the housing, so that the wire fixing member 50 is installed on the housing.

[0059] Correspondingly, the wire fixing member 50 is provided with a threading hole 53, and the threading hole 53 is connected to the inner cavity of the shell to ensure that the cable 40 can pass through the inner cavity of the shell into the threading hole 53. The cross-sectional shape of the threading hole 53 can be circular or rectangular, etc., and its size can be selected according to parameters such as the diameter of the cable 40, which is not limited in this article. When the cable 40 is inserted into the threading hole 53, the present embodiment also makes the cable 40 and the threading hole 53 seal. Specifically, a sealing ring 61 can be provided outside the cable 40, and the sealing ring 61 is used to form a more reliable sealing relationship between the cable 40 and the threading hole 53. In order to further improve the sealing reliability between the cable 40 and the wire threading hole 53, in another embodiment of the present application, during the installation of the cable 40, glue can be coated on the outside of the cable 40, so that when the cable 40 is inserted into the wire threading hole 53, the glue can be used to seal the gap between the outer surface of the cable 40 and the inner wall of the wire threading hole 53, which can also make the assembly reliability between the cable 40 and the wire threading hole 53 relatively higher.

[0060] In the case where the wire fixing member 50 and the through hole are sealed and connected by the sealing ring 61, in order to further improve the assembly reliability of the sealing ring 61 and further improve the sealing effect of the sealing ring 61, in another embodiment of the present application, the through hole can be a stepped hole, and the wire fixing member 50 can include a stepped portion. During the assembly of the wire fixing member 50, the stepped portion of the wire fixing member 50 can be matched with the stepped hole in the axial upper limit of the through hole, so that the sealing ring 61 can also be squeezed and set between the stepped portion and the stepped hole along the axial direction of the through hole, further improving the connection tightness between the wire fixing member 50 and the housing and the sealing ring 61. Of course, if Figure 5 As shown, during the formation of the through hole, a step hole needs to be formed corresponding to the installation direction of the wire fixing member 50 to ensure that when a part of the wire fixing member 50 is extended into the through hole, the step portion of the wire fixing member 50 can limit each other with the step structure of the through hole and squeeze the sealing ring 61.

[0061] As described above, a sealed connection relationship can be formed between the cable 40 and the threading hole 53 of the wire fixing member 50 by means of glue dispensing, and glue can be applied to the outside of the cable 40 before the cable 40 is installed. In order to reduce the difficulty of installing the cable 40 and improve the sealing reliability between the cable 40 and the threading hole 53, in another embodiment of the present application, the wire fixing member 50 is provided with a receiving cavity and a glue dispensing hole 52, wherein the glue dispensing hole 52 and the threading hole 53 are both connected to the receiving cavity, and the glue dispensing hole 52 is located on the side of the receiving cavity away from the inner cavity of the shell, the receiving cavity can be filled with sealant 62, and the sealant 62 is used to block the threading hole 53.

[0062] In the above embodiment, by further providing a glue dispensing hole 52 and a receiving cavity on the wire fixing member 50, and making the glue dispensing hole 52 located on the side of the wire fixing member 50 away from the housing, that is, the glue dispensing hole 52 is located on the outside of the wire fixing member 50 as a whole, it is convenient to dispense glue from the glue dispensing hole 52 into the receiving cavity. Figure 5 As shown, a threading hole 53 is formed on the left end of the wire fixing member 50, and a glue dispensing hole 52 can be provided at the right end of the wire fixing member 50 or at a position near the right end in the middle of the wire fixing member 50. A receiving cavity is provided in the middle of the wire fixing member 50, and the receiving cavity extends to the threading hole 53 and the glue dispensing hole 52, so as to ensure that when glue is dispensed from the glue dispensing hole 52 into the receiving cavity, the glue can flow through the receiving cavity to the threading hole 53 to block the threading hole 53, thereby ensuring that the inside of the shell and the outside of the shell form a more reliable isolation relationship. In addition, in this case, the cross-sectional size of the glue dispensing hole 52 can be relatively large to facilitate the glue dispensing work.

[0063] Of course, in the case where the wire fixing member 50 is provided with a threading hole 53, in order to ensure that the cable 40 can pass through the wire fixing member 50 to be electrically connected to the heating and deicing assembly 30, the wire fixing member 50 also needs to be provided with a wire outlet hole 54, and the wire outlet hole 54 is connected with the threading hole 53, so that the cable 40 can pass through the threading hole 53 and the wire outlet hole 54 to the outside of the wire fixing member 50. In the above embodiment, the threading hole 53 is connected with the inner cavity. In this case, the wire outlet hole 54 can be connected with the threading hole 53 through the accommodating cavity. Correspondingly, in the process of using the sealant 62 to block the threading hole 53, the wire outlet hole 54 can also be blocked by the sealant 62, thereby further improving the sealing reliability of the housing.

[0064] Of course, if Figure 5 As shown, the outlet hole 54 can be arranged on the side where the glue dispensing hole 52 is located. In this case, it is convenient to carry out the threading work of the cable 40. In another embodiment of the present application, as shown in FIG. Figure 6 As shown, the wire outlet hole 54 can also be set on the side of the wire fixing member 50, that is, the wire outlet hole 54 can be located on the side adjacent to the side where the glue dispensing hole 52 is located. Correspondingly, the side where the wire outlet hole 54 is located can also be adjacent to the side where the threading hole 53 is located. This can prevent the presence of the cable 40 in the wire outlet hole 54 from hindering the glue dispensing work at the glue dispensing hole 52, thereby preventing the existence of a glue dispensing blind spot in the accommodating cavity, resulting in a hollow situation in the accommodating cavity, which has an adverse effect on the sealing reliability of the threading hole 53.

[0065] As described above, the cable 40 can be used to supply power to the heating and deicing assembly 30. Generally, the cable 40 includes a wire core and a wire sheath. The wire core is formed of a metal material for conducting electricity, and the wire sheath is generally formed of an insulating material such as plastic to ensure that the cable 40 has good safety. Considering that as the use time of the photoelectric turntable increases, the wire sheath of the cable 40 may be aged or damaged. In this case, in order to further prevent water vapor or dust from entering the interior of the housing of the bracket assembly 11 from the gap between the wire sheath and the wire core of the cable 40, in a specific embodiment of the present application, the cable 40 may include a first wire segment 41, a second wire segment 42, and a third wire segment 43, wherein the first wire segment 41 and the third wire segment 43 both include a wire core and a wire sheath wrapped around the wire core, and the second wire segment 42 includes a bare wire core, and the wire cores of the first wire segment 41, the second wire segment 42, and the third wire segment 43 are connected in sequence to ensure that the cable 40 can be powered normally. Intuitively speaking, the second wire segment 42 can be the wire core remaining after removing the wire sheath. In the specific implementation process, the wire sheath can be removed from a section of the cable 40, and this section of the cable 40 is the second wire segment 42, and the wire cores of the cable 40 adjacent to both sides of the second wire segment 42 that are still wrapped with the wire sheath are the first wire segment 41 and the third wire segment 43, respectively.

[0066] Based on the above situation, during the installation of the cable 40, the second wire segment 42 can be located at the through hole, and the end of the first wire segment 41 away from the second wire segment 42 can be located inside the shell. Accordingly, the end of the third wire segment 43 away from the second wire segment 42 can be used to electrically connect with the heating and deicing assembly 30. At the same time, the wire core of the second wire segment 42 and the wire sheath of the first wire segment 41 can be wrapped with continuous sealant 62, so that the gap between the wire core and the wire sheath of the end of the first wire segment 41 connected to the second wire segment 42 is blocked by the sealant 62. In this case, even if the wire sheath of the third wire segment 43 located outside the shell is aged or damaged, impurities such as water vapor and dust cannot enter the shell of the bracket assembly 11 from the gap between the wire sheath and the wire core of the cable 40, which can further improve the safety and reliability of the components in the bracket assembly 11.

[0067] Of course, in the process of sealing the wire sheath and wire core of the first wire segment 41 with the sealant 62, the sealant 62 can also be made to seal with the through hole of the housing. Optionally, the sealant 62 can be directly applied to the outside of the cable 40, and the sealant 62 can be connected to the inner wall of the through hole to block the gap between the through hole and the cable 40. In the case where the optoelectronic turntable disclosed in the embodiment of the present application includes the above-mentioned wire fixing member 50, the sealant 62 can also be filled in the accommodating cavity of the wire fixing member 50, and the sealant 62 can be made to wrap the wire sheath of the first wire segment 41 and the wire core of the second wire segment 42, and the sealant 62 and the wire fixing member 50 can be used to block the gap between the cable 40 and the through hole.

[0068] In addition, in the process of wrapping the sealant 62 outside the first line segment 41 and the second line segment 42, the sealant 62 can also be extended to the portion of the third line segment 43 that is connected to the second line segment 42, thereby further enhancing the protection effect on the core of the second line segment 42 and maximally preventing the core of the second line segment 42 from short circuiting and other unexpected situations.

[0069] In the above-mentioned embodiment, it is introduced that the detection chamber 21 of the photoelectric turntable can rotate relative to the first arm 112 and the second arm 113 to change its pitch angle. Furthermore, the photoelectric turntable disclosed in the embodiment of the present application can not only adjust the pitch angle position of the detection component by pitch rotation, but also adjust the circumferential azimuth angle of the detection component to improve the detection range of the detection component.

[0070] like Figure 1 and Figure 2 As shown, in one embodiment, the optoelectronic turntable also includes a fixed seat 12, an azimuth drive device installed on the fixed seat 12 and a rotating seat connected to the azimuth drive device, the pitch bracket is connected to the rotating seat, the azimuth drive device drives the pitch bracket to rotate, and the rotation center direction of the azimuth drive device is perpendicular to the rotation center direction of the pitch drive device.

[0071] The fixed seat 12 is used to assemble the photoelectric turntable on a fixed foundation, such as the fixed seat 12 is installed on a building; the fixed seat 12 is installed on an equipment rack; the fixed seat 12 is installed on a mobile platform, etc. The azimuth drive device is installed in the fixed seat 12 and can drive the rotating seat to rotate, so that the rotating seat and the pitch bracket, detection chamber 21 and other components installed on the rotating seat rotate, and then the detection azimuth of the detection component is adjusted accordingly, and the detection azimuth adjustment is flexible. Among them, the rotation centerline of the rotating seat is perpendicular to the rotation centerline of the detection chamber 21, so that the detection component can detect different azimuths and different pitch angles, and the detection range is wide. Optionally, the azimuth drive device is set as a motor.

[0072] In one embodiment, the rotating seat includes a cover body and a sleeve portion protruding from the cover body, the sleeve portion is inserted into the fixed seat 12 and connected to the azimuth driving device. The cover body is covered on the top of the fixed seat 12, and the pitch bracket is connected to the cover body.

[0073] The cover body is covered on the top end surface of the fixed seat 12 to prevent foreign matter from falling into the fixed seat 12. Optionally, an elastic seal is provided between the cover body and the fixed seat 12 to seal the gap between the two and enable the rotating seat to rotate relative to the fixed seat 12. The pitch bracket is installed on the rotating seat and rotates with the rotating seat, and the two are detachably connected. Optionally, the pitch bracket is locked and connected to the rotating seat by a fastener so that the two are locked and connected as a whole. Optionally, the rotating seat and the pitch bracket are plug-in connected, and the plug-in matching positioning accuracy of the two is high to realize a quick plug-in and pull-out split structure, which is easy to install and maintain.

[0074] The plug-in connection between the rotating seat and the pitch bracket includes: 1. The rotating seat partially protrudes and can be inserted into the pitch bracket; 2. The pitch bracket partially protrudes and can be inserted into the rotating seat; 3. The rotating seat and the pitch bracket can be inserted into each other to improve the tightness of the combination.

[0075] In one embodiment, the pitch bracket is provided with a tubular plug-in shaft, and the rotating seat is provided with a plug-in hole matching the plug-in shaft. The pitch bracket abuts against the rotating seat, and the plug-in shaft is correspondingly inserted into the plug-in hole, so that the two are combined into an integrated structure. Among them, the plug-in shaft is arranged at the bottom of the pitch bracket, that is, the plug-in shaft is formed by partially protruding from the surface of the bracket body 111 to form a tubular protrusion. It is worth mentioning that the bracket body 111 can also be provided with other tubular protrusions to be plugged into the pitch bracket to improve the stability of the plug-in fit. Optionally, the bracket body 111 can also be fixed to the rotating seat by fasteners or snap-fit ​​structures to improve the ability of the pitch bracket to resist external force impact. For example, the fixed seat 12 is provided with at least two studs, and the pitch bracket is provided with a through hole. The pitch bracket abuts against the fixed seat 12, so that the studs are correspondingly inserted into the through holes and connected with connectors such as nuts.

[0076] The detection assembly, the pitch drive device and other electrical components need to be connected to the power supply and the control circuit to perform the detection function and the adjustment function. Optionally, the detection assembly, the pitch drive device and other electrical components can be connected to the control circuit through a signal line.

[0077] In one embodiment, the photoelectric turntable includes a plug-in first conductive member installed on the pitch bracket and a second conductive member installed on the rotating seat, and the plug-in first conductive member and the second conductive member are plug-in conductively connected. The detection component, the pitch drive device and other electrical components are connected to the first conductive member, and the pitch bracket is plug-in connected to the rotating seat, then the first conductive member and the second conductive member are conductively connected, and the detection component, the pitch drive device and other electrical components are connected to the control circuit through the second conductive member, so that the pitch bracket or the detection chamber 21 does not need to be provided with a signal line connection structure. In addition, the first conductive member and the second conductive member are plug-in conductively connected, and the pitch bracket and the rotating seat realize a quick plug-in split connection, which is convenient for disassembly and assembly. Optionally, the first conductive member is set as an upper floating aviation plug, and the second conductive member is set as a lower floating aviation plug that matches the upper floating aviation plug.

[0078] In an optional embodiment, the first conductive member is installed in the plug shaft, and the second conductive member is installed in the plug hole. The plug shaft is tubular and protrudes from the pitch bracket, and the first conductive member is arranged in the tubular space of the plug shaft. The plug shaft is provided with mounting ribs or support plates to install the second conductive member, and the relative positions of the two are accurate. The second conductive member is arranged in the plug hole, wherein the plug hole is provided with mounting ribs or support plates to install the second conductive member, and the relative positions of the two are accurate. The plug shaft is inserted into the plug hole in a directional manner so that the first conductive member and the second conductive member are correspondingly plugged and matched, and the plugging stability is good and the plugging precision is high.
