[0014] The present invention has the following beneficial effects: 1. In the present invention, when the floating plates on both sides of the multiple rotating plates are subjected to the buoyancy of water, the floating plates will drive the rotating plates to rotate and cause the lifting ring to slide upward. When the lifting ring slides upward, the flexible belt will be stretched to make it unfold in the square groove. At the same time, the sliding of the lifting ring will drive the multiple C-shaped rods to rise synchronously. When the C-shaped rod rises, it drives the piston rod to slide upward inside the hollow cylinder and squeezes the gas in the hollow cylinder so that the gas in the two hollow cylinders enters the inside of the flexible belt to expand. The flexible belt will fill the inside of the square groove when it expands and unfolds. The filling of the square groove by the flexible belt can quickly fill and seal the motor under the buoyancy of water when the aircraft is launched, so as to achieve the purpose of waterproofing. The flexible belt is squeezed by gas to enter and expand to fill the gap in the square groove, so that the sealing effect can be further enhanced with the help of the pressure generated by the gas expansion, and the waterproof function can be automatically started when the motor enters the water, thereby improving the practicability and reliability of the device.

[0015] 2. In the present invention, when the sliding shaft slides, it will first squeeze the side wall of the right-angle block through the inclined groove so that the winding belt squeezes the side wall of the flexible belt, and then when the sliding shaft slides upward, it will drive the right-angle block to slide upward, and unwind the winding belt while making the winding belt contact with the side wall of the flexible belt. Subsequently, when the piston rod rises, an adsorption force will be generated between the bottom of the piston rod and the hollow cylinder to adsorb the gas in the winding belt, which can make the winding belt and the side wall of the flexible belt come into close contact and firmly adsorb to enhance the stability of the flexible belt in water, thereby reducing the displacement or shaking of the flexible belt under the impact of water flow and water pressure of different water flows when the aircraft is flying in the water, resulting in waterproof leakage, thereby further enhancing the waterproof ability in water.

[0016] 3. In the present invention, when the floating plate drives the rotating plate to rotate under the buoyancy of water and pushes the lifting ring to slide upward, the floating plate will be in an upright state and be at the bottom of the flexible layer. When the aircraft flies in the water in an inclined posture, the water flow will impact the flexible layer through multiple circular holes, causing it to expand and contact the side wall of the lifting ring when the water flow impacts it. Since the flexible layer has a certain flexibility, when the water flow impacts the flexible layer and makes it contact the side wall of the lifting ring, it can reduce the floating plate from floating outward and resetting under the action of buoyancy when the aircraft is flying at an angle, causing the lifting ring to slide downward, and reduce the sealing gap of the flexible belt that has been expanded due to the tilting floating of the floating plate due to the tilting floating of the aircraft. This can improve the stability of the floating plate when the aircraft is flying at an angle, while reducing the gap between the flexible belt and the square groove, thereby enhancing the stable waterproofness of the motor when it is flying at an angle in water.

The two square grooves are symmetrically distributed with the middle of the outer shell 113 as the center. Placement grooves 114 are opened on the left and right sides of the square grooves. The top bolts of the outer shell 113 are connected with a cover plate. First, the duct 111 is connected to the main body 1 and the main body 1 is connected to the aircraft. Then the motor 121 is placed inside the outer shell 113 and the top cover is connected to the outer shell 113.

[0027] The power assembly 12 includes a motor 121 slidably connected to the inside of the housing 113, and a fan 122 is fixedly connected to the output end of the motor 121; The buoyancy assembly 21 includes a floating plate 211 rotatably connected to the left and right outer walls of the rotating plate 201, a connecting rod 212 is rotatably connected to the top of the rotating plate 201, an arc spring is fixedly connected to the side wall of the rotating plate 201, and one end of the arc spring away from the rotating plate 201 is fixedly connected to the side wall of the housing 113; Among them, the rotating plate 201 is rotatably connected to the inside of the C-shaped frame 112. When the floating plates 211 on both sides of the rotating plates 201 are subjected to the buoyancy of the water, they will drive the rotating plates 201 to rotate and cause the lifting ring 221 to slide upward. When the lifting ring 221 slides upward, it will stretch the flexible belt 223 to make it unfold in the square groove.

[0028] The auxiliary part includes a lifting ring 221 rotatably connected to one end of the plurality of connecting rods 212 away from the rotating plate 201, the lifting ring 221 is slidably connected to the outer surface of the housing 113, the bottom of the lifting ring 221 is open, and the side wall of the lifting ring 221 is provided with a plurality of circular holes; Among them, a plurality of flexible layers 222 are fixedly connected to the bottom of the lifting ring 221; The lifting assembly 22 includes a tension spring fixedly connected to the top of the flexible layer 222, and the top of the tension spring is fixedly connected to the top inner wall of the lifting ring 221; Among them, two flexible belts 223 are fixedly connected to the inner wall of the lifting ring 221, and the bottom of the flexible belt 223 is fixedly connected to the bottom inner wall of the square groove. The flexible belt 223 will fill the inside of the square groove when it is expanded and unfolded. The filling of the square groove by the flexible belt 223 can quickly fill and seal the motor 121 under the buoyancy of the water when the aircraft is launched, thereby achieving the purpose of waterproofing.

[0029] The C-shaped rod 301 is slidably connected to the inside of the placement groove 114; one end of the C-shaped rod 301 close to the lifting ring 221 is fixedly connected to the side wall of the lifting ring 221; The sliding assembly 31 includes a sliding shaft 311 fixedly connected to the side wall of the C-shaped rod 301 located inside the placement groove 114, the side wall of the sliding shaft 311 is provided with an oblique groove, the top of the sliding shaft 311 is fixedly connected to an auxiliary spring, and the top of the auxiliary spring is fixedly connected to the top inner wall of the placement groove 114; Among them, the bottom of the sliding shaft 311 is fixedly connected with a piston rod 313, and the outer surface of the piston rod 313 is slidably connected with a hollow cylinder 312, and the bottom of the hollow cylinder 312 is fixedly connected to the inside of the placement groove 114. When the sliding shaft 311 slides, it will first squeeze the side wall of the right-angle block 321 through the inclined groove so that the winding belt 322 squeezes the side wall of the flexible belt 223. Then, when the sliding shaft 311 slides upward, it will drive the right-angle block 321 to slide upward, and while unwinding the winding belt 322, the winding belt 322 will contact the side wall of the flexible belt 223.

[0030] The extrusion piece includes a right-angle block 321 slidably connected to the inside of the placement groove 114, a tension spring is fixedly connected to the bottom of the right-angle block 321, and the bottom of the tension spring is fixedly connected to the bottom inner wall of the placement groove 114; Among them, the top of the right-angle block 321 is rotatably connected with a winding belt 322, the bottom of the winding belt 322 is fixedly connected to the bottom inner wall of the placement groove 114, and the side wall of the winding belt 322 is provided with a plurality of adsorption holes. Then, when the piston rod 313 rises, an adsorption force is generated between the bottom of the piston rod 313 and the hollow cylinder 312 to adsorb the gas in the winding belt 322, so that the winding belt 322 can be in close contact with the side wall of the flexible belt 223 and firmly adsorbed to enhance the stability of the flexible belt 223 in water.

[0031] The fitting assembly 32 includes two suction pipes 323 fixedly connected to the outer surface of the hollow cylinder 312, and one end of the suction pipe 323 away from the winding belt 322 is fixedly connected to the side wall of the flexible belt 223; Among them, the flexible belt 223 is connected to the interior of the hollow cylinder 312 through the suction pipe 323, and the side wall of the winding belt 322 is fixedly connected with a torsion spring 324. The end of the torsion spring 324 close to the flexible belt 223 is fixedly connected to the side wall of the right-angle block 321. When the water flow impacts the flexible layer 222 and makes it contact with the side wall of the lifting ring 221, it can reduce the floating plate 211 from floating outward and resetting under the action of buoyancy when the aircraft is tilted and flying, causing the lifting ring 221 to slide downward.

[0032] When in use, first connect the duct 111 to the main body 1 and then connect the main body 1 to the aircraft, then place the motor 121 inside the outer shell 113 and connect the top cover to the outer shell 113, then install and connect the fan 122 to the motor 121, and then start the C-shaped frame 112. When working, the C-shaped frame 112 will drive the fan 122 to rotate and drive the aircraft to fly. When the aircraft is flying in the air, the wind force generated by the rotation of the fan 122 will dissipate the heat of the motor 121 through the square groove on the side wall of the outer shell 113. When the aircraft dives into the water, the multiple floating plates 211 will float upward due to the buoyancy of the water and drive the flexible belt 223 to fill the square groove through the lifting ring 221 to achieve the effect of sealing and waterproofing the motor 121.

[0033] When the floating plates 211 on both sides of the multiple rotating plates 201 are subjected to the buoyancy of the water, the rotating plates 201 will be driven to rotate. When the multiple rotating plates 201 rotate, the lifting ring 221 will slide upward through the connecting rod 212. When the lifting ring 221 slides upward, the flexible belt 223 will be stretched so that the flexible belt 223 is unfolded in the square groove in the shell 113. At the same time, when the lifting ring 221 slides upward, the sliding of the lifting ring 221 will drive the multiple C-shaped rods 301 to rise synchronously. When the C-shaped rod 301 rises, it will drive the piston rod 313 to slide upward inside the hollow cylinder 312 through the sliding shaft 311. When the piston rod 313 slides upward, The gas at the piston rod 313 and the top of the hollow cylinder 312 is squeezed so that the gas in the two hollow cylinders 312 enters the interior of the flexible belt 223 to expand it. When the flexible belt 223 expands and unfolds, it fills into the interior of the square groove. The filling of the square groove by the flexible belt 223 can quickly fill and seal the motor 121 under the buoyancy of the water when the aircraft is launched, thereby achieving the purpose of waterproofing. The flexible belt 223 is used to expand the squeezed gas to fill the gap in the square groove. The sealing effect can be further enhanced with the help of the pressure generated by the gas expansion. The waterproof function can be automatically activated when the motor 121 enters the water, thereby improving the reliability of the device.

[0034] When the C-shaped rod 301 rises and drives the sliding shaft 311 to slide upward, the sliding of the sliding shaft 311 will first squeeze the side wall of the right-angle block 321 through the inclined groove, so that the right-angle block 321 squeezes the side wall of the flexible belt 223 through the winding belt 322. Then, when the sliding shaft 311 slides upward, it will drive the right-angle block 321 to slide upward through the inclined groove on the sliding shaft 311. When the right-angle block 321 slides upward, it will unwind the winding belt 322 and make the winding belt 322 contact with the side wall of the flexible belt 223. Then, the sliding shaft 311 drives the piston rod 313 upward. When the cylinder 312 is lifted up, an adsorption force will be generated between the bottom of the piston rod 313 and the hollow cylinder 312. At this time, the adsorption force will adsorb the gas in the winding belt 322 through the suction pipe 323, so that the winding belt 322 can be in close contact with the side wall of the flexible belt 223 and firmly adsorbed to enhance the stability of the flexible belt 223 in the water, thereby reducing the displacement or shaking of the flexible belt 223 under the impact of different water flows and water pressure when the aircraft is flying in the water, resulting in waterproof leakage, thereby further enhancing the waterproof ability in the water.

[0035] When the floating plates 211 on both sides of the rotating plate 201 drive the rotating plate 201 to rotate under the buoyancy of the water and push the lifting ring 221 to slide upward, the floating plates 211 will be in an upright state and at the bottom of the flexible layer 222. Then, when the aircraft flies in the water in an inclined posture, the water flow will impact the flexible layer 222 through the multiple circular holes on the lifting ring 221. After being impacted, the flexible layer 222 will expand and contact the side wall of the lifting ring 221 when impacted by the water flow. Since the flexible layer 222 has a certain flexibility, when the water flow impacts the flexible layer 222 to make it contact with the lifting ring 221, When the side wall of the ring 221 is in contact, the floating plate 211 can be reduced from floating outward and resetting under the action of buoyancy when the aircraft is tilted, causing the lifting ring 221 to slide downward, and the flexible belt 223 that has expanded due to the tilting and floating of the floating plate 211 due to the tilting of the aircraft can be reduced. The sealing gap can be reduced, thereby improving the stability of the floating plate 211 when the aircraft is tilted and reducing the gap between the flexible belt 223 and the square groove, thereby enhancing the stability of the motor 121 when it is tilted in water. The output ends of the fan 122 and the motor 121 are detachable.
