[0007] The buoyancy regulating unit 308 contains an oil pan for regulating the buoyancy, thereby indirectly adjusting the buoyancy of the entire sea anchor power generation device, causing the sea anchor power generation device to float up and down.
[0008] The propeller power generation cabin contains a flow meter device.
[0009] There are four of the plurality of counterweight ball connecting ropes 302 , reel connecting ropes 303 , propeller connecting cables 307 , and propeller module connecting cables 311 .
[0010] The propeller is a circumferential device with an impeller having a certain angle, and the number of the blades is not limited and can be multiple.
[0011] A method for applying the automatically retractable sea anchor power generation device based on ocean currents is characterized by the following steps:
[0012] Step 1: The buoy station 1 floats on the water surface, and the cable 2 and the sea anchor power generation device 3 are connected; the sea anchor power generation device 3 is in a folded and stored state and coiled inside the pod 103 of the buoy station 1;
[0013] Step 2: When the shore-based terminal sends a signal indicating whether to release the connecting cable 2 and the sea anchor generator 3, or when the current meter inside the pod 103 detects that the current velocity inside the diving range of the current water area satisfies the release information of the buoy station 1, the buoy station 1 releases, and the winding device inside the pod 103 starts to release the connecting cable 2 and the sea anchor generator 3;
[0014] Step 3: When the current meter in the propeller power generation cabin 309 detects that the current at the current depth meets the power generation task requirements, the reel 305 starts working, the sea anchor body 301 in the sea anchor power generation device 3 is unfolded, and all cables in the sea anchor power generation device 3 are unfolded to the maximum state;
[0015] Step 4: The counterweight ball 314 presses down the end of the sea anchor generator 3 close to the connecting cable 2. The buoyancy adjustment unit 308 uses the oil-fried structure to adjust the buoyancy state of the other end of the sea anchor generator 3, changing the inclination angle of the sea anchor generator 3. When the current meter device inside the propeller power generation cabin 309 detects that the water velocity is no longer increasing at the current depth, the buoyancy adjustment stops.
[0016] Step 5: After the power generation process is completed, the reel 305 retracts the cables and ropes in the sea anchor power generation device, thereby folding the sea anchor body 301. At this time, the oil naan adjusts the buoyancy to the maximum, and the winding device in the pod 103 begins to recycle the connecting cable 2. Under the action of the connecting cable 2 and the buoyancy of the oil naan, the sea anchor power generation device 3 as a whole begins to float rapidly, and finally retracts it into the pod 103, and the entire work is completed.

[0043] The antenna and fixture 101 contains the buoy station's communication equipment (including a communication antenna, a global positioning system antenna, a remote control antenna, and an indicator light), and is fixed in the center of the equipment compartment. Its exterior is made of a rough, non-metallic, lightweight composite material. In addition to its antenna function, the antenna and fixture can be fixed to intelligent devices such as unmanned vessels, manned vessels, and large surface buoys, and can operate simultaneously with other intelligent devices. The pod 103 connects the antenna and fixture 101 and the equipment compartment 102. This pod is a water-permeable compartment and contains winding devices such as reels and cables, as well as materials thereof, and is primarily used for hoisting and deploying the sea anchor power generation device 3.
[0044] The anchor body 301 is a truncated cone-shaped composite non-metallic material with openings of different sizes at both ends, and the material has high strength, high elasticity, light weight and thin wall; the counterweight ball connecting rope 302 is a lightweight and high-strength non-metallic rope connecting the hook 304 and the counterweight ball 314; the reel connecting rope 303 is a lightweight and high-strength non-metallic rope connecting the reel 305 and the hook 304; the hook 304 is a lightweight and high-strength non-metallic composite material part fixed to the edge of the larger opening end of the anchor body 301, which is used to fix the reel connecting rope 303 and the counterweight ball connecting rope 302; the reel 305 can recycle and release the connecting rope between the counterweight ball 314 and the reel 305, and at the same time serves to connect the propeller connecting cable 307 and the sea anchor connecting cable 3 06, and is used for bidirectional transmission of electrical energy; the sea anchor connection cable 306 and the propeller connection cable 307 are high-strength and lightweight connection data cables, which are used to provide data and power supply connections between the propeller 310 and the buoy station 1, wherein the sea anchor connection cable 306 connects the reel 305 and the counterweight ball 314 at the center of the large open end of the sea anchor body 301, and the propeller connection cable 307 connects the small open end of the sea anchor body 301 and the reel 305 and is arranged in four circumferential directions; the buoyancy adjustment unit 308 is fixed to the outside of the propeller power generation cabin 309, and contains an oil pan with adjustable buoyancy, thereby indirectly adjusting the buoyancy of the sea anchor power generation device 3 as a whole, so that the sea anchor power generation device 3 can float and descend (the sea anchor power generation device 3 as a whole The initial buoyancy is less than the gravity); the propeller power generation cabin 309 contains power generation equipment and a flow meter device (located inside the propeller power generation cabin, and its measuring sensor is located outside the propeller power generation cabin, and the device can measure the water flow velocity at the current position) for power generation, energy storage and speed measurement. On the one hand, the kinetic energy brought by the rotation of the propeller 310 is converted into electrical energy and temporarily stored, and the generated electrical energy is transmitted through the propeller module connecting cable 311, the propeller connecting cable 307 and the sea anchor connecting cable 306.

The propeller cover 313 is a protective device that fits over the propeller 310. The counterweight ball 314 is a weighted counterweight device with cables and ropes connected to it.

When a signal is manually sent from the shore-based terminal (this is the manual working mode, and the buoy station 1 can only be manually controlled to release the connecting cable 2 and the sea anchor power generation device 3) or when the current meter inside the pod 103 detects that the flow velocity inside the diving range of the current water area is high (this is the automatic working mode), the buoy station 1 is released, and the winding device inside the pod 103 begins to slowly release the connecting cable 2 and the sea anchor power generation device 3; when the current meter in the propeller power generation cabin 309 detects that the current energy at the current depth is large and meets the power generation task requirements, the reel 305 starts to work, and the sea anchor body 301 in the sea anchor power generation device 3 is unfolded. , all the cables in the sea anchor power generation device 3 are unfolded to the maximum state; at this time, the counterweight ball 314 presses down the end of the sea anchor power generation device 3 close to the connecting cable 2, and the buoyancy adjustment unit 308 uses the oil naan structure to adjust the buoyancy state of the other end of the sea anchor power generation device 3, changing the inclination angle of the sea anchor power generation device 3, and stops changing the buoyancy when the current meter device inside the propeller power generation cabin 309 detects that the water flow velocity no longer increases under the current depth; after the power generation process is completed, the reel 305 retracts the cables and ropes in the sea anchor power generation device, thereby folding the sea anchor body 301. At this time, the oil naan adjusts the buoyancy to the maximum, and the winding device in the pod 103 begins to recycle the connecting cable 2. Under the action of the connecting cable 2 and the oil naan buoyancy, the sea anchor power generation device 3 as a whole begins to float rapidly, and finally retracts it into the pod 103, and the entire work is completed.
