For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0025] Reference Figure 1-8 The present invention proposes a mobile power cable for ships, including a cable body 1, a mobile ring 2 and a fastening assembly for locking the position of the mobile ring 2, wherein: the cable body 1 is internally shielded with tinned copper wire braiding to reduce interference during the operation of the cable body 1. The cable body 1 is internally wrapped with a reinforced light non-woven fabric to make the cable body 1 compact and stable, with a uniform outer diameter. The mobile ring 2 is sleeved on the cable body 1, and a protective ring 3 is provided on one side of the mobile ring 2 close to the end of the cable body 1; refer to Figure 4 , Figure 6As shown, after the ends of the two cable bodies 1 are connected, the protective ring 3 on one of the cable bodies 1 will be sleeved on the outer circumference of the other protective ring 3, and then the connection between the ends of the two cable bodies 1 can be effectively protected by the two protective rings 3. The fastening assembly includes a plurality of movable rods 4 and a driving member 5. A plurality of grooves 6 arranged in an annular shape are provided on the outer side of the movable ring 2. The movable ring 2 is located at the bottom of the groove 6 and has the performance of elastic deformation. The plurality of movable rods 4 are arranged one by one with the plurality of grooves 6. The middle position of the movable rod 4 is hinged in the groove 6, and one end of the movable rod 4 is against the bottom of the groove 6. Specifically, a horizontally arranged cross bar 7 is provided in the groove 6. The middle position of the movable rod 4 is hinged on the cross bar 7. An elastic member 8 connected to the movable rod 4 is provided in the groove 6. The driving member 5 is installed on the movable ring 2 and can move along the length direction of the movable ring 2. When the two cable bodies 1 are in Figure 4 When in the state shown, the driving member 5 on the left side can be used to drive the top end of the movable rod 4 to rotate clockwise, and the elastic member 8 on the left side will be stretched, so that the bottom end of the movable rod 4 will be pressed against the bottom of the groove 6, and the bottom position of the groove 6 will be pressed and elastically deformed, and the left movable ring 2 will be fixed to the left cable body 1; the driving member 5 on the right side can be used to drive the top end of the movable rod 4 to rotate counterclockwise, and the elastic member 8 on the right side will be stretched, so that the bottom end of the movable rod 4 will be pressed against the bottom of the groove 6, and the bottom position of the groove 6 will be pressed and elastically deformed, and the right movable ring 2 will be fixed to the right cable body 1. The elastic deformation causes the movable ring 2 to be pressed and connected with the cable body 1, that is, the positions of the protective rings 3 on the two cable bodies 1 are fixed. Figures 4 to 6 When the lock between the moving ring 2 and the cable body 1 is released by the driving member 5, the movable rod 4 will return to the initial position under the restoring force of the elastic member 8, so as to facilitate the next work.

[0026] Further, see Figure 3 , Figure 5 , Figure 7 A smooth protrusion 9 is provided at one end of the movable rod 4 close to the bottom of the groove 6, and the smooth protrusion 9 is against the bottom of the groove 6. When the driving member 5 drives the movable rod 4 to rotate, the smooth protrusion 9 will be pressed against the bottom position of the groove 6, and the rotation is flexible, so that it can better undergo elastic deformation.

[0027] Reference Figure 3 , Figure 5 , Figure 7-8The driving member 5 includes a locking ring 51 and a pressing ring 52. The inner side of the locking ring 51 is provided with an internal thread, and the outer side of the moving ring 2 is provided with an external thread. The locking ring 51 and the moving ring 2 are installed through the internal thread and the external thread. The pressing ring 52 is installed at one end of the locking ring 51 close to the movable rod 4, and the pressing ring 52 and the locking ring 51 are coaxially arranged. Figure 5 When the locking ring 51 on the left is rotated to move to the right, the pressing ring 52 on it will be driven to move to the right. During the movement of the pressing ring 52 to the right, the top end of the movable rod 4 will be pressed clockwise, and then the bottom end of the movable rod 4 will press against the bottom position of the groove 6 to elastically deform. The elastic deformation makes the left movable ring 2 and the left cable body 1 to be pressed and connected, that is, the position of the left movable ring 2 is fixed on the left cable body 1; when the locking ring 51 on the right is rotated to move to the left, the position of the right movable ring 2 is fixed on the right cable body 1 in the same way as the above working principle, and then the positions of the protective rings 3 on the two cable bodies 1 will be fixed.

[0028] Reference Figure 1-3 When the locking ring 51 and the moving ring 2 are not connected by internal and external threads, that is, the locking ring 51 is in a free state and can slide freely left and right on the moving ring 2, a retaining ring 10 can be provided at the end of the moving ring 2 away from the protective ring 3 to prevent the locking ring 51 from slipping out of the moving ring 2.
