[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. For the cable reel used in the deep-sea underwater repeater, by setting the V-shaped seat, square groove, square block, support column, spring and roller, during the process of the reel rotating to wind and unwind the cable, the V-shaped seat is below the reel, the spring is above the V-shaped seat, and the spring drives the square block to slide in the square groove through the support column. The square block plays a role in limiting the support column in the square groove, avoiding the situation of the support column flipping. The elastic force generated by the spring makes the roller fit on the outer wall of the cable wound on the reel, and the roller rotates with the reel, which will not affect the winding and unwinding of the cable. Through the support of the roller, the cable will not freely sag in the water due to its weight and length during the winding and unwinding process, reducing the risk of cable entanglement and damage.

[0012] 2. For the cable reel used in the deep-sea underwater repeater, by setting the support rod, adjusting screw, driven gear, connecting block, pipe sleeve and guide wheel, during the winding and unwinding process, the end of the cable passes through between a plurality of guide wheels. The adjusting motor drives the driven gear to rotate through the linkage rod and the driving gear. The rotation of the driven gear drives the adjusting screw to rotate. The adjusting screw rotates above the connecting block and drives the connecting block to slide in the sliding grooves on both sides of the support rod through the cooperation with the adjusting nut. During the sliding process of the connecting block, it drives the pipe sleeve and the linkage rod to move up or down. The pipe sleeve drives the limiting rod to move up or down, and the guide wheel follows the limiting rod to move. In this way, the winding and unwinding angle of the cable can be adjusted, guiding the cable, reducing the risk of entanglement, and improving the practicability of the cable reel.

Specific implementation manner

[0018] The technical solution of this patent will be further described in detail below in combination with the specific implementation manner.

[0019] As Figures 1-4 shown, the present utility model provides a technical solution: a cable reel for a deep-sea underwater repeater, including a base 1, two supports 2 are fixedly installed above the base 1, a bearing 3 is provided on one side of the support 2, and a reel 4 is rotatably connected between the two supports 2 through the bearing 3. An output motor 5 is provided on one side of one of the supports 2, and the output end of the output motor 5 penetrates through the support 2 and is connected to the reel 4. A V-shaped seat 6 is fixedly installed above the base 1, and the position of the V-shaped seat 6 is located below the reel 4. A plurality of square grooves 7 are opened in the V-shaped seat 6, and a square block 8 is slidably connected in the square groove 7. Through the cooperation between the square block 8 and the square groove 7, under the action of the spring 10, the support column 9 slides in the square groove 7 through the square block 8. The square block 8 plays a role in limiting the support column 9 in the square groove 7 to prevent the support column 9 from rotating during the movement. A support column 9 is fixedly connected above the square block 8, and the support column 9 slides in the square groove 7 through the square block 8. A spring 10 is sleeved outside the support column 9. A roller 11 is rotatably connected between two corresponding support columns 9 through a pin shaft. Due to the provision of the roller 11, under the action of the spring 10, the roller 11 adheres to the surface of the cable below the reel 4 through the support column 9 to support the cable and prevent the cable from sagging due to its own gravity, affecting the winding and unwinding of the cable;

The adjusting screw rod 16 drives the sleeve 19 to rise or fall through the connecting block 15, thereby adjusting the height and direction of the guiding of the guiding wheel 24. A driven gear 18 is fixedly connected to the end of the adjusting screw rod 16. The support rod 12 is sleeved with two sleeves 19. A plurality of limiting rods 23 are fixedly connected between the two sleeves 19. A plurality of guiding wheels 24 are slidably connected to the outer walls of the plurality of limiting rods 23. Through the cooperation between the guiding wheels 24 and the limiting rods 23, the cable passes through between the four guiding wheels 24, and the guiding wheels 24 slide on the outer walls of the limiting rods 23. In this way, the guiding wheels 24 can play a guiding role in the cable during the winding and unwinding process, avoiding the cable from being entangled during the winding and unwinding process. Both ends of the connecting block 15 penetrate through the sliding slots 14 and are connected to the inner wall of the sleeve 19. A linkage rod 20 is provided on one side of the sleeve 19. Due to the provision of the linkage rod 20, under the action of the linkage rod 20, the driving gear 21 is matched with the driven gear 18, so that the two sleeves 19 can rise or fall synchronously, improving the accuracy of the sleeve 19 when driving the guiding wheel 24 to guide. The linkage rod 20 penetrates through the sleeve 19. A driving gear 21 is fixedly installed on the outer wall of the linkage rod 20 inside the sleeve 19. The driving gear 21 meshes with the driven gear 18. One end of the linkage rod 20 is provided with an adjusting motor 22.

[0021] The working principle of the present utility model is as follows: When using the cable reel, one end of the cable passes through between a plurality of guiding wheels 24. The adjusting motor 22 drives the linkage rod 20 and the driving gear 21 to rotate. The driving gear 21 drives the driven gear 18 to rotate. The driven gear 18 drives the adjusting screw rod 16 to rotate above the connecting block 15. At the same time, the adjusting screw rod 16 cooperates with the adjusting nut 17 to drive the connecting block 15 to slide in the sliding slot 14. The connecting block 15 drives the sleeve 19 to move up or down, thereby adjusting the height of the limiting rod 23 and the guiding wheel 24. The output motor 5 drives the reel 4 to rotate through the bearing 3 between the two brackets 2 to wind and unwind the cable. The V-shaped seat 6 is below the reel 4. The support column 9 above the V-shaped seat 6 slides in the square groove 7 through the square block 8 under the action of the spring 10, driving the roller 11 to fit on the outer wall of the cable below the reel 4 to support the cable, thereby winding and unwinding the cable.
