[0036] Example 1

[0037] As shown in Figure 1 The present embodiment provides a water rescue device, which comprises a hull, the hull comprising a cabin part and a propulsion part. The propulsion part is connected to the rear end of the cabin part, and the propulsion part is provided with a shaftless propeller.

[0038] The cabin part is divided into front, middle and rear parts. The front part is arc-shaped and provided with a handle 1. A rescue operation lamp 2 and a camera 3 are arranged at the front end of the front part. The rescue operation lamp 2 comprises a rescue illuminating lamp and a rescue warning lamp. The rescue illuminating lamp is an energy-saving LED lamp, and the rescue warning lamp is an orange flashing light.

[0039] A part of the front end of the cabin part is inclined outwardly, forming a taper from front to back, which is beneficial to overcome the resistance of water. A side handle 5 and a rescue towing rope hanging point 4 are arranged on the outer side of the cabin part, which are convenient for connecting the towing rope, controlling and fixing the water rescue device.

[0040] The middle part of the hull part is provided with a communication module 9, an energy storage power supply 10 and a control circuit board 11. The communication module 9 of the embodiment is a wireless communication based on a honeycomb network, including a data communication sub-module and a wireless image transmission sub-module.

The propulsion direction and speed of the shaftless propeller 12 can be controlled according to the working instructions issued by the communication module 9. The existing conventional motor control circuit board can be used for the control circuit board. Artificial control handles can also be arranged on the cabin body. The personnel on the cabin body can control the speed and direction of the rescue device. The authority of remote control and artificial control of the cabin body can be set in the background. The energy storage power supply is a lithium battery pack. The energy storage power supply, the communication module and the control circuit board are sealed in the cabin body by waterproof cover plates.

[0041] A hatch is arranged on the upper end surface of the bow of the hull. The hatch is provided with a waterproof hatch door. Rescue articles can be placed in the hatch.

[0042] The rear part of the cabin part is arranged in two parts which are symmetrical to each other. There is a bifurcation between the two parts. The personnel can control by lying in the middle of the bifurcation, or the transported personnel can be placed in the middle. The rear part of the cabin part is connected with the propulsion part.

[0043] Two propulsion parts are arranged in the embodiment, which are symmetrically arranged at the rear part of the cabin part. The shaftless propeller 12 is arranged in the propulsion part. The shaftless propeller 12 is connected with the energy storage power supply 10. The water inlet 7 and the water outlet 8 are arranged on the propulsion part. The water inlet 7 and the water outlet 8 are respectively located at the front end and the rear end of the shaftless propeller 12. The shaftless motor rotates to form negative pressure in the propeller 12, so that water is sucked from the water inlet 7 and sprayed from the water outlet 8 to push the rescue device forward. The water inlet guide groove 20 is arranged on the cabin body and connected with the water inlet 7. After the cabin body is put into water, a part of the cabin body (about 1 / 3) is below the water surface, and water can smoothly pass through the water inlet into the propeller.

[0044] For example, Figure 4As shown, in the embodiment, the shaftless propeller comprises a casing 13, a driving motor and a propeller 17. The driving motor is a permanent magnet motor, comprising a rotor 14 and a stator 15. The stator 15 is connected with the casing, and the stator 15 is arranged outside the rotor 14, and the rotor 14 rotates inside the stator 15. The outer wall of the rotor 14 is provided with permanent magnets 16, and the central shaft of the rotor 14 is a hollow shaft, and the inner wall of the hollow shaft is welded with the propeller 17. The inner wall of the hollow shaft of the rotor 14 is also connected with a bearing 18, the outer wall of the bearing 18 is connected with the hollow shaft, and the inner wall is connected with the casing. The rotor and the stator are fixed in relative position through the connection with the casing. As shown in the figure, Figure 5 As shown, in the embodiment, two bearings 18 are arranged, and the propeller 17 is welded at the middle position of the axial direction of the hollow shaft of the rotor, and the bearings 18 are arranged on both sides of the propeller 17. One bearing can also be arranged, and the propeller is installed in parallel. The other structures of the driving motor can be realized by using the existing technology.

[0045] In the embodiment, the hull is stitched by flexible composite material or rubber material, and the inside is an inflatable air bag. An air valve 6 is arranged on the hull, and the inflatable valve is connected with the energy storage power supply 10, and the inflation and deflation of the hull is realized through the air valve 6. The folded water rescue device can be accommodated in the storage box, and a charger matched with the energy storage power supply is arranged in the box. A handle is arranged on the upper part of the box body, which is convenient for carrying and transferring.

[0046] Specifically, the working process of the water rescue device provided in the embodiment is as follows: when rescuing, first, open the energy storage power supply 10, open the air valve 6 to inflate the hull; after the inflation is completed, put the water rescue device into the water, and remotely control the rescue personnel. The communication module 9 receives the instruction and transmits it to the circuit control board. The circuit control board starts the shaftless propeller 12 according to the working instruction, the water jet 8 sprays water flow to push the water rescue device forward; open the camera 3 and the rescue operation lamp 2 in the middle of the forward journey, which is convenient for observing the water surface and finding the trapped personnel. The camera 3 is connected with the communication module 9, and the picture taken by the camera 3 is transmitted to the rescue personnel in real time through the communication module 9, so that the rescue personnel can observe the disaster situation and adjust the forward speed and direction of the water rescue device at any time.

[0047] Embodiment 2

[0048] The cabin body in the embodiment is symmetrically arranged on the upper and lower surfaces. When put into the water, the surface entering the water is the lower surface, and the surface corresponding to the surface is the upper surface. Each surface is provided with a water inlet guide groove 20 and an upper water inlet 71 and a lower water inlet 72. The upper and lower water inlets are communicated to form a water inlet chamber 21. An air separation baffle 213 is arranged on the water inlet. As shown in the figure, Figure 5As shown, the air blocking baffle 213 is used to block the communication between the upper water inlet 71 and the air, and the water enters the propeller from the lower water inlet 72. When the propeller rotates, negative pressure is formed in the propeller, and the water flow is sucked in. If the upper water inlet 71 is not blocked by air, the air will enter the propeller at the same time as the water flow, which will affect the water inlet and water jet efficiency, and the output power of the propeller will be reduced.

[0049] The air blocking baffle 213 is a structure that can be switched up and down, that is, the baffle 213 can be switched up and down on the water inlet chamber 21, and is used to close one water inlet. Due to the symmetrical arrangement of the two sides of the cabin, when the life-saving device is thrown into the water during emergency rescue, the water inlet surface is random, and the position of the baffle 213 needs to be switched according to the water inlet surface to ensure that the baffle always closes the upper water inlet 71 during work. When the ship body collides with obstacles or is overturned by wind and wave impact during operation, the baffle 213 needs to be switched to the other side to still close the upper water inlet, so as to ensure the output thrust of the propeller.

[0050] The specific structure of the switching baffle has various implementation manners.

[0051] Manner one: The upper and lower surfaces of the front wall of the water inlet chamber 21 and the upper and lower surfaces of the rear wall of the water inlet chamber are provided with clamping grooves for placing the baffle, and a hole is formed in the side wall of the cabin to communicate the clamping grooves on the upper surface of the front wall and the upper surface of the rear wall, and a hole is formed to communicate the clamping grooves on the lower surface of the front wall and the lower surface of the rear wall. The width of the hole is slightly larger than the width of the baffle 213. When switching is needed, the baffle 213 is taken out from the hole communicating the lower clamping grooves and placed in the hole communicating the upper clamping grooves.

[0052] Manner two: as shown in the figure Figure 8 When the baffle 213 is switched to the upper water inlet 71 of the water inlet chamber 21, it blocks the water from entering the water inlet chamber from the upper water inlet 213, and the water enters from the lower water inlet 72. The upper surface of the front wall of the water inlet chamber 21 and the upper surface of the rear wall of the water inlet chamber are provided with rails 214, and the baffle 213 is arranged on the rails 214. The baffle can be manually pushed to move up and down on the rail to complete the switching. The baffle can also be switched up and down by a controller. The rail 214 is provided with a sliding block, the baffle is arranged on the sliding block, the rail 214 is provided with a motor, the motor drives the sliding block to move up and down on the rail 214, and drives the baffle 213 to move up and down along the rail 214. The motor is connected with the cabin control circuit board, and the baffle can be controlled to move up and down by the controller, and the switching direction. The connection between the motor and the sliding block, and the control circuit board can be realized by using existing mature technology.

[0053] Manner three: the middle part of the front wall of the water inlet chamber and the upper and lower surfaces of the rear wall are respectively provided with clamping grooves for placing the baffle, and a hole is formed in the side wall of the cabin to communicate the clamping grooves of the front wall and the rear wall. The width of the hole is slightly larger than the width of the baffle. When switching the baffle, the baffle is taken out from the hole connected with the lower surface of the front wall and the rear wall, and is inserted into the hole connected with the upper surface of the front wall and the rear wall.

[0054] Mode four: as shown in Figure 6 The rear wall of the water inlet chamber 21 is provided with a track 214 connecting the upper and lower surfaces, and the baffle 213 is a foldable structure with a hinge in the middle. The two sides of the hinge are provided with springs to restore the baffle to its original state after folding. When switching the baffle 213, pull the baffle from the lower surface of the rear wall to the upper surface of the rear wall through the track to close the upper water inlet 71. At this time, water enters from the lower water inlet 72. The baffle is at its shortest distance when passing through the middle of the track, and the baffle is folded. After reaching the upper surface, the baffle is restored to its original state under the action of the spring. Under the action of the spring, the baffle will not slide downward without external force. A slider can also be provided on the track 214. The slider is connected to a drive motor. The motor drives the slider to move up and down. The motor is connected to the cabin control circuit board. The motor is controlled by the controller to drive the baffle to switch up and down. The connection of the motor and the slider, as well as the control circuit board, can be realized by using existing mature technology.

[0055] Mode five: as shown in Figure 7 The air baffle 213 in the water inlet chamber 21 is made of a floating body material and can move up and down in the water inlet chamber 21. When the propeller rotates, the water flow accelerates and pushes the floating air baffle 213 upward to tightly adhere to the upper water inlet 71, achieving the function of closing the upper water inlet and isolating air.

[0056] The above are only a few implementation methods. As long as the structure of the baffle switching up and down is within the scope of the invention, it is within the protection scope of the invention.

[0057] Example 3

[0058] The difference between this embodiment and example 1 is that the propeller center is provided with a fixed shaft hole, a fixed shaft is arranged in the fixed shaft hole, the fixed shaft is connected with the propeller through a bearing, the fixed shaft passes through the propeller in the middle, and the end is connected with the shell. The relative position relationship between the fixed rotor and the stator. The motor rotor rotates to drive the propeller to rotate and drive the propeller to move. The shell can wrap the drive motor in the middle. The propeller inlet and outlet are provided with a net, and the fixed shaft is connected with the center of the net through bolts.

[0059] Example 4

[0060] The inflatable air bag of the cabin is provided with a rapid inflation device. The rapid inflation device adopts the starting device of the automobile anti-explosion air bag. This embodiment is a pyrotechnic gas generator, as shown in Figure 13The system includes a gas generating chamber 231 and a cooling filter layer 232. A vent 233 is provided between the gas generating chamber 231 and the cooling filter layer 232. The gas generating chamber 231 contains a gas generating agent and an ignition device 235. The cooling filter layer 232 contains cooling and filtering materials, and an outlet 234 is provided on the outer shell of the cooling filter layer 232. Both the vent 233 and the outlet 234 are equipped with diaphragms to prevent the gas generating agent or residue from passing through. Both the vent 233 and the outlet 234 are equipped with filter screens that only allow gas to pass through, preventing residue or gas generating agent from passing through and causing leakage. The gas generating agent is an azide-based gas generating agent composed of sodium azide and transition metal oxides. The cooling and filtering materials are substances such as iron sand or granular sodium bicarbonate that are heat-resistant or easily endothermic and decompose. Under high temperatures, they can still maintain their complete cooling and filtering form, or absorb a large amount of heat due to decomposition, thereby reducing the temperature. The ignition device 235 is located in the gas generating chamber and includes an ignition shell, an igniter 236 inside the ignition shell, and an ignition hole 237 on the ignition shell. The ignition device 235 performs ignition through the ignition hole 237. The start button of the ignition device 235 is connected to the outer wall of the cabin. When in operation, pressing the start button activates the ignition device 235, ignites the igniter 236, and detonates the gas generating agent through the ignition hole 237. The gas generating agent releases a large amount of nitrogen gas, which quickly fills the gasbag, just like a car airbag can rapidly inflate the hull.

[0061] Example 5

Figure 11 The image shows a traditional shafted propeller, with the central hole of the propeller connecting to the motor output shaft. Figure 12 The image shows the shaftless propulsion system of the present invention, which uses a propeller housed within the hollow rotor shaft of the shaftless motor. The propeller is positioned at a depth 3 cm above the horizontal plane of symmetry of the aircraft. Figure 11 The thruster speed is set to 7800 rpm. Figure 11 The thruster speed is set to 3000 rpm. The calculated thrust and torque of the thruster are shown in the table below.
