[0023] like Figure 1-Figure 3 As shown, the present application provides an underwater robot retraction and deployment device, including a support frame 1, the support frame 1 having a top plate 101, a retraction and deployment assembly 2 mounted on the top plate 101, the retraction and deployment assembly 2 including two sets of connecting frames 202 fixedly mounted on the top plate 101, a reeling roller 201 connected between the two sets of connecting frames 202, and a cable wound on the reeling roller 201;

[0024] A winding motor 203 is fixedly mounted on the side of the connecting frame 202. The output end of the winding motor 203 is connected to the winding roller 201. The winding roller 201 is adapted to rotate along with the output end of the winding motor 203 to wind the cable.

[0025] A guide mechanism is mounted on the top plate 101, which is suitable for evenly winding the cable onto the winding roller 201. The guide mechanism includes a concave frame 204 fixedly mounted on the top plate 101, a screw rod 205 movably connected to the concave frame 204, a screw rod sleeve 206 threadedly connected to the screw rod 205, and a servo motor 208 fixedly mounted on the side of the concave frame 204. The output end of the servo motor 208 passes through the concave frame 204 and is connected to the screw rod 205.

[0026] Two sets of limiting rods (not shown) are connected to the concave frame 204. The screw sleeve 206 is movably connected to the two sets of limiting rods. The limiting rods are suitable for linearly limiting the movement of the screw sleeve 206.

[0027] A lifting ring 207 is fixedly mounted on the screw rod sleeve 206. The cable passes through the lifting ring 207. One end of the lifting ring 207 is connected to the underwater robot body 209. The screw rod 205 is adapted to rotate along with the output end of the servo motor 208, so that the screw rod sleeve 206 moves linearly on the two sets of limiting rods, and then can rotate synchronously with the winding roller 201, so that the cable is evenly wound on the winding roller 201.

[0028] A cleaning assembly 3 is mounted on the top plate 101. The cleaning assembly 3 includes a mounting frame 301 fixedly mounted on the top plate 101, a rotating motor 302 fixedly mounted on the mounting frame 301, and a first pulley 303 fixedly mounted on the output end of the rotating motor 302.

[0029] Two sets of bearing seats 304 are fixedly mounted on the mounting frame 301, and a cleaning shaft 305 is movably mounted between the two sets of bearing seats 304. The cleaning shaft 305 is a hollow structure, and a second pulley 306 is fixedly mounted on one end of the cleaning shaft 305. A belt is connected between the second pulley 306 and the first pulley 303;

[0030] The first pulley 303 is adapted to rotate along with the output end of the rotary motor 302, so as to drive the second pulley 306 to rotate via the belt, thereby driving the cleaning shaft 305 to rotate;

[0031] A plurality of cleaning brushes 307 are fixedly mounted on one end of the cleaning shaft 305. The plurality of cleaning brushes 307 are arranged in a ring shape. The cleaning brushes 307 are in contact with the cable and pass through the cleaning shaft 305. The cleaning brushes 307 are adapted to rotate synchronously with the rotation of the cleaning shaft 305 to clean the surface of the cable.

[0032] Working principle:

[0033] When in use, the cable passes through the lifting ring 207 and the cleaning shaft 305, and then the winding motor 203 is started to flip the cable wound on the winding roller 201 to lower it, and then the underwater robot body 209 at one end of the cable is put into the position to be submerged;

[0034] After use, the winding motor 203 is started again to rotate forward, and the servo motor 208 is started synchronously, so that the winding motor 203 drives the winding roller 201 to rewind the cable, and the servo motor 208 synchronously drives the cable to move back and forth, so that the cable is evenly wound on the winding roller 201;

[0035] The rotating motor 302 is started synchronously to rotate the first pulley 303, the first pulley 303 drives the second pulley 306 to rotate, the second pulley 306 drives the cleaning shaft 305 to rotate, and the cleaning shaft 305 drives the cleaning brush 307 to rotate to clean the cable surface.

[0036] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
