In the following description, specific details are set forth in order to provide a thorough understanding of the present invention. The invention can be implemented in a number of ways different from those described herein and similar generalizations can be made by those skilled in the art without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 4, the deep-sea current-power conversion unit according to the present invention includes an outer ring 1 and an inner ring 2, the outer ring 1 and the inner ring 2 are both circular in cross section, the inner ring 2 is located inside the outer ring 1, the inner ring 2 and the outer ring 1 are coaxially disposed, the outer ring 1 and the inner ring 2 are fixedly connected by a plurality of connection blocks 11, the connection blocks 11 are disposed at intervals along the circumferential direction of the outer ring and the inner ring, and in this embodiment, the deep-sea current-power conversion unit includes three connection blocks 11 disposed at even intervals along the circumferential direction. The center pin department of outer loop 1 and inner ring 2 is equipped with spindle ring 9, and spindle ring 9's outer wall passes through several connecting rod I3 and inner ring 2's inside wall fixed connection to make and become fixed connection's overall structure between outer loop 1, inner ring 2 and the spindle ring 9, connecting rod I3 sets up along the annular outer wall interval of spindle ring. A coaxial generator 8 is arranged in an inner hole of the main shaft ring 9, and the coaxial generator 8 rotates in the main shaft ring 9, namely, the coaxial generator 8 is rotatably connected with the main shaft ring 9.

The slide is formed before the internal surface of outer loop 1 and the surface of inner ring 2, and slider 15 is located the slide, and outer loop 1, inner ring 2 and slider 15 all have strong magnetism, and are magnetic force repulsion between slider 15 and outer loop 1, the inner ring 2, consequently the slider 15 does the in-process of circular motion along the slide, all can not produce the friction between outer loop 1 and the inner ring 2. In order to ensure that the sliding block 15 can smoothly make circular motion in the slideway, the two sides of the sliding block 15 facing the outer ring 1 and the inner ring 2 are respectively fixed with an arc-shaped sliding rail 13, at the moment, the arc-shaped sliding rail 13 also has strong magnetism, and the arc-shaped sliding rail 13 and the outer ring 1 and the inner ring 2 are both repelled by magnetic force, so that the sliding block 15 can be ensured to smoothly make circular motion between the outer ring 1 and the inner ring 2 under the guiding action of the arc-shaped sliding rail 13.

Annular holes are formed in the annular circumferential surfaces of the outer ring 1 and the inner ring 2, one side, facing the outer ring 1, of the sliding block 15 is connected with the power floating ball 5 located outside the outer ring 1 sequentially through the connecting rod II 16 and the flexible spring 12, and the connecting rod II 16 penetrates through the annular hole in the outer ring 1 and can slide in the annular hole. A connecting rod I14 is fixed on one side of the sliding block 15 facing the inner ring 2, and the connecting rod I14 penetrates through a circular hole in the inner ring 2 and can slide in the circular hole. The other end of connecting rod I14 passes through connecting rod II 7 and coaxial generator 8 fixed connection, and this end still is connected with bracing piece 4 through reset spring 6, and the top and the reset spring 6 of bracing piece 4 are connected, the bottom of bracing piece 4 and the bottom fixed connection of the inside wall of inner ring 2. The main shaft ring 9 is correspondingly provided with an annular hole, when the slide way formed by the inner ring 1 and the outer ring 2 of the slide block 15 slides in the process, the slide block 15 can drive the connecting rod II 7 to slide in the annular hole through the connecting rod I14, so that the coaxial generator 8 in the main shaft ring 9 is driven to rotate, and the coaxial generator 8 generates electric power. In this embodiment, the connecting rod I14 and the connecting rod II 7 can be of an integrated structure.

The half wall of the annular outer side wall of the outer ring 1 is provided with a plurality of non-return hooks 10, and the non-return hooks 10 are arranged at intervals along the half annular outer side wall of the outer ring 1. One end of the non-return hook 10 is fixedly connected with the outer side wall of the outer ring 1, the other end of the non-return hook 10 is hook-shaped, and the non-return hook 10 inclines towards the rotation direction of the sliding block 15. And a stop lever is arranged on the connecting rod II 16 fixedly connected with the sliding block 15, and when the sliding block 15 rotates clockwise and reversely, the stop lever rotates along with the sliding block 15. Since the non-return hook 10 is inclined to the rotation direction of the slide block 15, the non-return hook 10 does not block the rotation of the stop lever. If certain force is applied to the sliding block 15, the sliding block 15 rotates anticlockwise, the non-return clamping hook 10 plays a role in blocking the stop lever, so that the stop lever and the sliding block 15 connected with the stop lever are blocked, and the sliding block 15 can only rotate clockwise along the slide way and cannot rotate reversely.

In this embodiment, the non-return hook 10 may adopt a structure as shown in fig. 4, the non-return hook 10 includes a rigid rod 1001 and a compression spring 1003, one end of the rigid rod 1001 is fixedly connected to the outer sidewall of the outer ring 1, the other end of the rigid rod 1001 is connected to the compression spring 1003 through a movable joint i 1002, the other end of the compression spring 1003 is connected to the outer sidewall of the outer ring 1 through a movable joint ii 1004, the rigid rod 1001 is inclined toward the rotation direction of the slider 15, and therefore the compression spring 1003 located between the rigid rod 1001 and the outer ring 1 is always in a compressed state. When the slider 15 drives the stop lever to move clockwise, the rigid rod 1001 is disposed along the rotation direction of the slider 15, so that no blocking effect is generated on the stop lever. When the stop lever moves counterclockwise, the rigid rod 1001 acts as a stop for the stop lever, preventing the stop lever and the slider 15 from rotating counterclockwise. That is, the slider 15 can only rotate in one direction within the slide under the action of the non-return catch 10.

The operation of the electric energy conversion unit is as follows. Assuming no ocean current action, the conversion unit is in the initial state shown in fig. 5, where the return spring 6 is at its original length and there is no spring force in the return spring 6. When ocean current is generated as shown in fig. 6, the outer ring 1, the inner ring 2 and the main shaft ring 9 are always in a standing state, the power floating ball 5 captures power caused by black tide, the power floating ball 5 continuously moves upwards under the action of buoyancy, at the moment, the power floating ball 5 drives the sliding block 15 to slide in a sliding way formed between the outer ring 1 and the inner ring 2 through the flexible spring 12 and the connecting rod II 16, and the sliding block 15 can do undamped circular motion along the sliding way due to the fact that the sliding block 15 is in a state of magnetic repulsion with the outer ring 1 and the inner ring 2. In the moving process of the sliding block 15, the distance between the sliding block 15 and the supporting rod 4 is continuously increased, as shown in fig. 6, the return spring 6 connecting the sliding block 15 and the supporting rod 4 is in a continuously stretched state, and the stretching force in the return spring 6 is gradually increased. When the power float ball 5 floats to a state that the radial direction thereof is parallel to the direction of the ocean current, that is, as shown in fig. 7, the ocean current has no power effect on the power float ball. At this time, under the elastic force of the return spring 6, the slider 15 is returned along the slide way, and the slider 15 returns to the position of the initial state again, so that the ocean current kinetic energy is received again, and the next circular motion cycle is carried out, and the cycle is repeated. In the rotation process of the sliding block 15, the coaxial generator 8 is driven to rotate through the connecting rod II 7 and generate electric power.
