Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 A waterproof switch mechanism includes a switch body 1, which includes a waterproof housing 102 and a connecting plate 104. A screw 107 is provided on the outer side of the waterproof housing 102, and the waterproof housing 102 is threadedly connected to one side of the connecting plate 104 via the screw 107. The waterproof housing 102 is used to prevent moisture from entering the interior of the switch body 1. A receiving groove 112 is provided on the outer surface of the waterproof housing 102, and a movable rod 101 is provided inside the receiving groove 112. The movable rod 101 passes through the waterproof housing 102. A compression spring 105 is provided at one end of the movable rod 101 near the receiving groove 112, and the other end of the compression spring 105 is located inside the receiving groove 112. An electronic switch 108 is provided at one end of the movable rod 101 near the connecting plate 104, and the bottom of the electronic switch 108 is located on the surface of the connecting plate 104. The electronic switch 108 is used to control power transmission. A humidity sensor is provided on one side of the connecting plate 104.

[0028] The inner wall of the waterproof housing 102 is fixedly provided with a sliding rod 106 by a drive block 114. Two sliding plates 103 are movably provided at the left and right ends of the sliding rod 106. The two sliding plates 103 are symmetrically arranged and are slidably disposed inside the waterproof housing 102. Electromagnetic plates for controlling the movement of the sliding plates 103 are provided on the left and right sides of the drive block 114. A fixing member 113 is provided on the inner wall of the waterproof housing 102 near the connecting plate 104. There are four sliding rods 106, each of which is symmetrically arranged inside the waterproof housing 102. A return spring 111 is provided at one end of each sliding rod 106 near the sliding plate 103. The return spring 111 is used to control the sliding plate 103 to return to its original position.

[0029] In use, multiple sliding rods 106, a drive block 114, and an electromagnetic plate are set up, and the electromagnetic plate is used to control the sliding plate 103 to move on the surface of the sliding rods 106. When the sliding plate 103 is not in working state, the reset spring 111 will restore the two sliding plates 103 to their initial positions through its own elasticity.

[0030] A sealing ring 109 is provided on the side of the waterproof housing 102 near the movable rod 101. The inner diameter of the sealing ring 109 is in close contact with the outer side of the movable rod 101. The sealing ring 109 is used to prevent water in the containment chamber from entering the interior of the waterproof housing 102 along the movable rod 101. A pressure sensor is provided on the side of the waterproof housing 102 near the compression spring 105 to detect the pressure value of the compression spring 105. A limiting plate 110 is provided on the outer side of the end of the movable rod 101 near the electronic switch 108. The diameter of the limiting plate 110 is larger than that of the sealing ring 109. When the compression spring 105 is in its initial state, the side of the limiting plate 110 facing the sealing ring 109 is in close contact with the side of the inner wall of the waterproof housing 102.

[0031] In use, by setting a sealing ring 109 inside the waterproof housing 102, when pressure is applied to the movable rod 101 so that the other end of the movable rod 101 presses the electronic switch 108, putting the electronic switch 108 in the open state, the sealing ring 109 is in close contact with the outer surface of the movable rod 101, thereby preventing water from flowing from the gap between the movable rod 101 and the waterproof housing 102 into the interior of the waterproof housing 102. In addition, when the movable rod 101 is in the initial state, due to the elasticity of the compression spring 105, the side of the limiting plate 110 facing the sealing ring 109 is in contact with the inner wall of the waterproof housing 102, thereby providing secondary protection for the gap between the movable rod 101 and the waterproof housing 102, preventing water from escaping into the interior of the waterproof housing 102 and causing damage to the electronic switch 108.

[0032] This utility model also provides an underwater drone, including a waterproof switch mechanism and an underwater drone body 2. The waterproof switch mechanism is fixedly disposed on the surface of the underwater drone body 2. The underwater drone body 2 includes a body shell 201. A first drive motor 202 is disposed on the surface of the body shell 201. A first propeller 203 for takeoff is disposed at the output end of the first drive motor 202. A support plate 205 is disposed inside the body shell 201. A drive motor is disposed inside the support plate 205. The drive motor is used to control the deflection of the rotating arm 204. A second drive motor 208 is disposed at the end of the rotating arm 204 away from the body shell 201. A second propeller 207 is disposed at the output end of the second drive motor 208. An integrated sensor 206 is disposed on one side of the rotating arm 204. The number of rotating arms 204, integrated sensors 206, second drive motors 208 and second propellers 207 are all provided in four. Each rotating arm 204, integrated sensor 206, second drive motor 208 and second propeller 207 are arranged in a circumferential array on the surface of the body shell 201.

[0033] In use, by setting up a drive motor and a rotating arm 204, and controlling the drive motor to deflect the drive arm away from the fuselage shell 201, the rotating arm 204 is perpendicular to the fuselage shell 201. Then, the first drive motor 202 and the second drive motor 208 are turned on simultaneously, so that the first propeller 203 and multiple second propellers 207 work at the same time, thereby achieving the take-off of the underwater drone. Secondly, when the underwater drone enters the water to operate, the drive motor is controlled to deflect the rotating arm 204 towards the fuselage shell 201 to avoid the resistance generated by the sudden entry into the water from instantly damaging the second propellers 207. When the underwater drone is in working condition, the integrated sensor 206 is used to detect various data in the air and underwater states respectively to ensure that the components inside the underwater drone are always working in a normal operating state.

[0034] In summary, during use, when the underwater drone is operating underwater, the waterproof outer shell 102 first blocks external water, preventing water from entering the interior of the waterproof outer shell 102 and causing a short circuit or damage to the electronic switch 108. When it is necessary to turn on the electronic switch 108, simply apply pressure to the movable rod 101, causing it to slide towards the electronic switch 108 inside the protective shell. The end of the movable rod 101 furthest from the waterproof outer shell 102 should then contact the electronic switch 108. Pressing the electronic switch 108 will then turn it on. The waterproof outer shell 102 is tightly connected to the surface of the connecting plate 104 via screws 107, thereby achieving the desired effect. The electronic switch 108 is completely isolated from the external space, thus ensuring that moisture cannot come into contact with the electronic switch 108 and avoid short circuit damage. At the same time, two sliding plates 103 are used to seal the left and right sides of the waterproof housing 102 respectively, preventing moisture from entering the interior from the left and right sides of the waterproof housing 102. As the movable rod 101 slides downward under external pressure, the sealing ring 109 in the waterproof housing 102 seals the gap between the movable rod 101 and the waterproof housing 102, preventing water from contacting the electronic switch 108 through the gap between the movable rod 101 and the waterproof housing 102, thereby achieving the effect of waterproofing the electronic switch 108.

[0035] Although the waterproof housing 102 and symmetrically arranged movable plates isolate the electronic switch 108 from the external space, thus achieving a waterproof effect, the water pressure on the waterproof housing 102 varies depending on the depth at which the underwater drone operates. If the sealing strategy is not adjusted in real time according to the water pressure, excessive water pressure may occur, putting pressure on the sealing ring 109 on the outside of the movable rod 101. This can cause the sealing ring 109 to shift, allowing external moisture to enter the interior of the waterproof housing 102 and come into contact with the electronic switch 108, resulting in damage. Therefore, the specific adjustment steps are as follows:

[0036] The compression state of the compression spring 105 at the end of the movable rod 101 is detected by a pressure sensor. Since the working water depth of the underwater drone is different, the water pressure is also different. When working in water with a higher depth, the water pressure will apply pressure to the end of the movable rod 101, so that the compression spring 105 is in a compressed state. The depth of the underwater drone and the water pressure it is subjected to can be determined by the amount of compression of the compression spring 105 detected by the pressure sensor.

[0037] When the pressure sensor detects that the compression of the compression spring 105 is within the preset range, it indicates that the underwater drone is not diving too deep and the water pressure it is under is within the normal range. No adjustments need to be made, and the underwater drone can continue to be used for underwater operations.

[0038] It is worth noting that when the underwater drone dives and the pressure sensor detects that the water pressure is continuously increasing, the electromagnetic plate is controlled to apply a magnetic repulsion force to the sliding plate 103 to ensure that the waterproof shell 102 and the sliding plate 103 always remain tightly connected, so as to avoid water seeping into the interior due to gaps caused by the increase in water pressure.

[0039] When the pressure sensor detects that the compression of the compression spring 105 is higher than the preset value range, it indicates that the underwater drone is diving at a deep depth and is experiencing high water pressure. The sealing strategy needs to be adjusted according to this water pressure condition. First, the electromagnetic plate is controlled to move the two symmetrically arranged sliding plates 103 towards the electronic switch 108 through magnetic attraction. As the two sliding plates 103 move, their edges come into close contact with the inner wall of the waterproof housing 102, causing the air pressure inside the waterproof housing 102 to increase. This puts pressure on the bottom end of the movable rod 101 within the waterproof housing 102, causing it to slide upwards rapidly, proportional to the external water pressure. Simultaneously, the upward sliding process of the movable rod 101... In the process, the limiting plate 110 is made to make tight contact with the side facing the sealing ring 109, and the bottom of the sealing ring 109 is sealed to prevent the sealing ring 109 from falling into the waterproof housing 102 due to high water pressure. During the movement of the sliding plate 103, the pressure sensor detects the pressure value of the compression spring 105 in real time. When the pressure value is proportional to the external water pressure, the electromagnetic plate is controlled to maintain a constant magnetic attraction force, so that the sliding plate 103 is always in the optimal position, thereby forming a stable state. This achieves dynamic adjustment of the internal pressure state according to the external water pressure value, thereby forming a balanced resistance with the external water pressure and preventing the sealing ring 109 from falling off due to excessive water pressure, which would allow water to enter the interior of the waterproof housing 102 and cause the electronic switch 108 to short-circuit or be damaged.
