3. A method of using the deep-sea mineral collection and transportation device according to claim 2, characterized in that, Includes the following steps: Step 1: The transport device (2) departs from the surface mother ship. First, it uses the electrical energy stored in the battery module (2-7) to draw the outside gas into the high-pressure gas storage chamber (2-6) through the air inlet (2-11) and pressurize it to the rated pressure before closing the air inlet (2-11). At the same time, it opens the ballast tank valve (2-8) to allow seawater to flow into the ballast tank (2-9). When a certain volume has been filled, the transport device (2) begins to submerge under the action of gravity. When the seawater completely fills the ballast tank (2-9), it closes the ballast tank valve (2-8). During the submersion, it will drive the generator (2-5) to generate electricity and store it in the battery module (2-7). At the same time, it will output a portion of the electrical energy to supply the control propeller (2-4) so ​​that the transport device can smoothly reach the designated location. Meanwhile, the mining device (1) operates continuously and stores the collected ore in the mine car storage bin (1-1). Step 2: The transport device (2) arrives near the mining device (1) and achieves precise docking between the transport device (2) and the mining device (1) through the mine car docking device (1-3) and the conveying device docking device (2-1). During the docking process, the mining device (1) operates continuously. Step 3: After the transport device (2) is fixedly connected to the mining device (1), the electrically controlled door (2-3) of the conveyor storage bin in the transport device (2) and the electrically controlled door (1-2) of the mine car storage bin in the mining device (1) open simultaneously. The minerals originally stored in the mine car storage bin (1-1) flow into the conveyor storage bin (2-2) under the combined action of the slope and gravity. At the same time, the mining device (1) operates continuously, and the newly collected minerals will also directly enter the conveyor storage bin (2-2). During the operation of the mining device (1), the transport device (2) can also maintain the stable operation of the mining device (1) by adjusting the propeller (2-4). When the conveyor storage bin (2-2) is filled to the rated capacity, the electrically controlled door of the conveyor storage bin in the transport device (2) is closed. 2-3) and the electric control door (1-2) of the mine car storage bin in the mining device (1), at this time the minerals collected by the mining device (1) will be stored in the mine car storage bin (1-1) and the operation will continue; after the electric control door is completely closed, open the ballast tank valve (2-8) and the air blowing port (2-10) to blow the high pressure gas stored in the high pressure storage chamber (2-6) into the ballast tank (2-9) through the air blowing port (2-10), and at the same time push the seawater in the ballast tank (2-9) to blow out through the ballast tank valve (2-8); when the seawater in the ballast tank (2-9) is completely blown out, close the ballast tank valve (2-8) and the air blowing port (2-10); control the hydraulic rod (101) in the mine car docking device (1-3) to extend to the designated position, de-energize the electromagnetic device (103) and release the magnetic force; Step 4: After the electromagnetic fixation is released, the transport device (2) begins to float due to buoyancy. The transport device (2) and the mining device (1) are safely and smoothly separated by the control propeller (2-4). During the floating process, the power generation device (2-5) will be activated to generate electricity and store it in the battery module (2-7). At the same time, a portion of the electricity will be output to supply the control propeller (2-4) so ​​that the transport device (2) can smoothly reach the designated position. Meanwhile, the mining device (1) will carry out uninterrupted operation and store the collected ore in the mine car storage bin (1-1). Step 5: After the transport device (2) arrives at the designated position on the water surface, it connects with the mother ship on the water surface, unloads the minerals from the storage bin (2-2) of the transport device, and puts them back on the water surface to complete one cycle. During this process, the mining device (1) operates continuously.

4. The method of using the deep-sea mineral collection and transportation device according to claim 3, characterized in that, Step two includes the following steps: Step 1: By adjusting the propeller (2-4), the transport device (2) is positioned approximately directly above the mining device (1) and moves synchronously with it. After synchronous movement, the cable automatic winding and unwinding device (201) in the conveyor docking device (2-1) releases the cable (203), which extends downward continuously under the gravity of the electromagnet (204). At the same time, the hydraulic rod (101) in the mine car docking device (1-3) is raised, driving the mounting platform (102) and the electromagnetic device (103) to the designated position. Step 2: After the electromagnetic device (103) is raised to the designated position, the power is turned on to generate magnetic force. At the same time, the propeller (2-4) and the cable automatic winding and unwinding device (201) are adjusted to make the electromagnet (204) move toward the electromagnetic device (103). When it moves to a certain range nearby, the electromagnet (204) is affected by the magnetic force and its concave and convex design to achieve precise docking with the electromagnetic device (103). Step 3: After the electromagnet (204) and the electromagnetic device (103) are connected, the automatic cable retraction device (201) retracts the cable (203), and the entire conveying device (2) is fully in contact with the mine car docking device (1-3) under the tension of the four cables (203). Furthermore, the simultaneous action of the four cables (203) avoids the problem of the conveying device (2) turning, thus achieving precise docking. Step 4: After the conveying device (2) and the mine car docking device (1-3) are docked, control the hydraulic rod (101) in the mine car docking device (1-3) to retract. After retracting to the designated position, the precise docking of the conveying device (2) and the mining device (1) is completed.
