The limiting column 505 movably passes through the first mounting plate 503, and a first spring 506 is sleeved on the outer wall of the limiting column 505.

[0031] Further Figure 7 As shown, fixed plates 300 are fixed on both sides of the inner wall of the barrel 100, and the winding rod 200 is rotatably connected between the two fixed plates 300. A coupling tooth 600 is fixed at one end of the outer wall of the winding rod 200, and a rotating shaft 602 is fixed to the top of one side of the fixed plate 300. A coupling rod 601 is fixed to the outer wall of the rotating shaft 602. The coupling rod 601 is detachably engaged with the coupling tooth 600, and the inner arc-shaped tooth surface of the coupling tooth 600 is an arc surface formed with the axis of the rotating shaft 602 as the center.

[0032] By setting the engaging tooth 600 and the engaging rod 601, the position of the engaging tooth 600 can be limited, and then the position of the winding rod 200 can be limited, so that after the winding rod 200 winds up the lifebuoy rope, the winding rod 200 will not rotate, so that the lifebuoy rope can be stably wound on the winding rod 200.

[0033] Further Figure 7 As shown, a first fixing plate 604 is fixed to the top of one side of the engaging tooth 600, a second fixing plate 606 is fixed to the bottom of the engaging rod 601, and a second spring 605 is fixed between the first fixing plate 604 and the second fixing plate 606 close to one side thereof.

[0034] By providing the second spring 605 , the engaging rod 601 can be stably engaged with the engaging tooth 600 , thereby limiting the position of the winding rod 200 .

[0035] Further Figure 2As shown, a mounting shell 403 is fixed to one side of the bottom tube 101, a servo motor 404 is fixed to the top of the inner wall of the mounting shell 403, a threaded rod 400 is rotatably connected between the inner walls of the bottom tube 101 away from one side, an output end of the servo motor 404 is fixed to one end of the threaded rod 400, the leveling sleeve 401 is movably connected to the outer wall of the threaded rod 400, a battery 402 is fixed to the bottom surface of the inner wall of the mounting shell 403, and the servo motor 404 is electrically connected to the battery 402.

[0036] The servo motor 404 is provided to enable the threaded rod 400 to reciprocate, thereby enabling the leveling sleeve 401 to reciprocate and drive the rope.

[0037] This scheme has the following working process: when the lifebuoy rope is to be reeled in, first manually rotate the rotating ring 700, the rotating ring 700 rotates to drive the connecting rope 603 to move, the connecting rope 603 moves to drive the clamping rod 601 to rotate, so that the clamping rod 601 is separated from the clamping tooth 600, and the position of the reeling rod 200 is unrestricted, and then operate the PLC controller 801 to make the servo motor 404 rotate, the servo motor 404 rotates to drive the threaded rod 400 to rotate, the threaded rod 400 rotates to drive the leveling sleeve 401 to move, and at the same time manually rotate the handle 201 to make the reeling rod 200 rotate, the speed sensor 800 can detect the speed of the reeling rod 200 and transmit the signal to the PLC controller 801, the PLC controller 801 controls the speed of the servo motor 404, so that when the reeling rod 200 reels the rope, the leveling sleeve 401 can follow the rope to be reeled in at the same time. The first spring 506 is compressed and the stacked ropes are pressed evenly. When the flattening sleeve 401 moves to the other end, the PLC controller 801 controls the servo motor 404 to rotate in the opposite direction, thereby causing the flattening sleeve 401 to move in the opposite direction, so that the rope can be evenly and neatly rolled up on the winding rod 200. Through the provided ball 406, the rope is passed through the flattening sleeve 401 and the ball 406 is used to protect the rope when the flattening sleeve 401 moves. After the rope is rolled up, the restriction on the rotating circle 700 is released, and the spring releases the elastic force, so that the clamping rod 601 is engaged with the clamping tooth 600, so that the position of the winding rod 200 is limited.

[0038] When the rope is taken out, the PLC controller 801 is operated to rotate the motor, pull the life buoy, and the movement of the life buoy drives the rope to be removed from the winding rod 200.

[0039] According to the above working process, it can be known that: by means of the winding rod 200, the rope can be wound on the winding rod 200, and by means of the barrel 100, the wound rope can be isolated and protected, so as to avoid the rope being easily weathered and broken after being exposed to the sun and rain, resulting in the situation that the rope cannot be used normally. By means of the leveling sleeve 401, threaded rod 400, servo motor 404, speed sensor 800 and PLC controller 801, the rope is evenly wound on the winding rod 200, and by means of the rolling ball 406, the rope can be protected during winding, so as to avoid the rope contacting with the inner wall of the leveling sleeve 401 and causing wear during winding, so that the rope can be evenly and neatly wound on the winding rod 200, thereby improving the rope winding efficiency and avoiding the situation that the rope is entangled when the rope is inserted into the barrel 100 and taken out, thereby affecting the rescue progress.

[0040] By setting the flattening shaft 500, the rope wound on the winding rod 200 can be flattened, and by setting the side rod 501 and the first spring 506, the flattening shaft 500 can move with the increase of the thickness of the wound rope on the winding rod 200, so that the rope can be further wound evenly and neatly on the winding rod 200, further improving the neatness of the rope after winding.

[0041] Further Figure 3 As shown, a rotation speed sensor 800 is fixed to the bottom surface of one side of the sleeve barrel 100, a PLC controller 801 is fixed to the bottom of one side of the outer wall of the sleeve barrel 100, and the servo motor 404 and the rotation speed sensor 800 are electrically connected to the PLC controller 801 respectively.

[0042] The speed sensor 800 is set up to detect the rotation speed of the winding rod 200, and then transmit the detected signal to the PLC controller 801. The PLC controller 801 controls the speed of the servo motor 404, so that when the winding rod 200 reels the rope, the leveling sleeve 401 can move synchronously with the rope to be reeled in, so that the rope is evenly reeled on the winding rod 200.

[0043] Further Figure 2 As shown, a symmetrically distributed annular limit box 701 is fixed to one side of the outer wall of the barrel 100, and a rotating circle 700 is rotatably connected inside the two annular limit boxes 701. A connecting rope 603 is fixed to the top surface of the clamping rod 601. The connecting rope 603 can be movably passed through the barrel 100 and fixed to the middle of the inner wall of the rotating circle 700.

[0044] By setting the rotating circle 700, when the rotating circle 700 rotates, the connecting rope 603 can be pulled, thereby driving the clamping rod 601 to rotate and separate from the clamping teeth 600, so that the position of the winding rod 200 is not limited.

[0045] In summary: when the life buoy rope is to be reeled in, first manually rotate the rotating ring 700, the rotating ring 700 rotates to drive the connecting rope 603 to move, the connecting rope 603 moves to drive the clamping rod 601 to rotate, so that the clamping rod 601 is separated from the clamping tooth 600, and the position of the reeling rod 200 is unrestricted, and then operate the PLC controller 801 to make the servo motor 404 rotate, the servo motor 404 rotates to drive the threaded rod 400 to rotate, the threaded rod 400 rotates to drive the leveling sleeve 401 to move, and at the same time manually rotate the handle 201 to make the reeling rod 200 rotate, the speed sensor 800 can detect the speed of the reeling rod 200 and transmit the signal to the PLC controller 801, the PLC controller 801 controls the speed of the servo motor 404, so that when the reeling rod 200 reels the rope, the leveling sleeve 401 can move synchronously with the rope to be reeled in, The rope is evenly wound on the winding rod 200. During the process of the rope being wound onto the winding rod 200, the flattening shaft 500 flattens the rope. As the thickness of the rope on the winding rod 200 increases, the flattening shaft 500 moves upward, and the first spring 506 is compressed, so that the stacked ropes are pressed evenly. When the flattening sleeve 401 moves to the other end, the PLC controller 801 controls the servo motor 404 to rotate in the opposite direction, thereby causing the flattening sleeve 401 to move in the opposite direction, so that the rope can be evenly and neatly wound on the winding rod 200. Through the provided rolling ball 406, the rope is passed through the flattening sleeve 401 and the flattening sleeve 401 moves. The rolling ball 406 can protect the rope. After the rope is wound, the restriction on the rotating circle 700 is released, and the spring releases the elastic force, so that the clamping rod 601 is engaged with the clamping tooth 600, so that the position of the winding rod 200 is limited.

[0046] When the rope is taken out, the PLC controller 801 is operated to rotate the motor, pull the life buoy, and the movement of the life buoy drives the rope to be removed from the winding rod 200.

[0047] The servo motor 404, the battery 402, the speed sensor 800 and the PLC controller 801 can all be purchased from the market, and are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
