[0023] Next, the present invention will be further described in conjunction with the accompanying drawings.

[0024] Such as Figures 1-6As shown in the figure, a mooring device with high safety includes a bottom plate 1. In the middle of the upper end surface of the bottom plate 1, two first fixing seats 2 are connected. A winding drum 3 is connected between the two first fixing seats 2. A protective cover 4 is arranged outside the winding drum 3. A set of locking mechanisms are arranged outside each of the two first fixing seats 2. Both ends of the winding drum 3 are connected to a driving mechanism. The front end of the upper end surface of the bottom plate 1 is connected to a limiting mechanism. The protective cover 4 includes an upper protective cover 41 and a lower protective cover 42. The upper protective cover 41 and the lower protective cover 42 are butt-connected. The winding drum 3 is located inside the upper protective cover 41 and the lower protective cover 42. An opening 43 is formed on the lower protective cover 42. Both ends of the upper protective cover 41 and the lower protective cover 42 are connected to the inner sides of the two first fixing seats 2. The upper protective cover 41 and the lower protective cover 42 protect the winding drum 3, which can prevent workers from being touched and involved when the winding drum 3 rotates.

[0025] Specifically, the driving mechanism includes a first gear 16. A first gear 16 is connected to each of the two rotating shafts 5. At the rear end of the upper end surface of the bottom plate 1, two second fixing seats 20 are connected. A transmission shaft 19 is inserted through the two second fixing seats 20. Both ends of the transmission shaft 19 protrude outside the two second fixing seats 20. A second gear 18 is connected to each end of the transmission shaft 19 respectively. The second gear 18 is connected to the first gear 16 through a gear belt 17. A third gear 21 is connected to the middle of the transmission shaft 19. The third gear 21 meshes with a fourth gear 22. The fourth gear 22 is connected to a first motor 23. The first motor 23 is connected to the rear end of the upper end surface of the bottom plate 1. When the first motor 23 is started, the first motor 23 drives the fourth gear 22 to rotate. The rotation of the fourth gear 22 drives the third gear 21 to rotate. The rotation of the third gear 21 drives the transmission shaft 19 to rotate. The rotation of the transmission shaft 19 drives the two second gears 18 to rotate. The rotation of the second gear 18 drives the gear belt 17, so that the gear belt 17 drives the first gear 16 to rotate. The rotation of the first gear 16 drives the winding drum 3 to rotate. The rotation of the winding drum 3 can wind or release the cable. This connection method drives the winding drum 3 to rotate from both ends of the winding drum 3, which can make the rotation of the winding drum 3 smoother and the winding or releasing of the cable more fluent.

[0026] Specifically, each end of the winding drum 3 is connected to a rotating shaft 5 respectively. The outer ends of the rotating shafts 5 pass through the protective cover 4 and the first fixing seat 2 and are located outside the first fixing seat 2. The stopping mechanism includes a stopping disc 6. A plurality of stopping grooves 7 are formed on the outer side wall of the stopping disc 6. The stopping disc 6 is connected to the rotating shaft 5. A limiting box 8 is connected to the outer side wall of the first fixing seat 2. A sliding groove 9 is formed in the limiting box 8. A plugging rod 10 is located in the sliding groove 9. The upper end of the plugging rod 10 passes through the limiting box 8 and contacts the outer side wall of the stopping disc 6. A retaining ring 15 is connected to the middle of the plugging rod 10. A spring 14 is sleeved above the retaining ring 15 on the plugging rod 10. The lower end of the plugging rod 10 is connected to a first electromagnet 12. The upper end face of the bottom plate 1 is connected to a second electromagnet 13. After the first electromagnet 12 and the second electromagnet 13 are energized, the first electromagnet 12 and the second electromagnet 13 repel each other. A ball groove is formed on the end face of the plugging rod 10 in contact with the stopping disc 6. A second ball 11 is movably connected in the ball groove. When the rotating shaft 5 on the winding drum 3 rotates, it drives the stopping disc 6 to rotate. When the winding drum 3 stops rotating, the first electromagnet 12 and the second electromagnet 13 are energized. The second electromagnet 13 pushes the first electromagnet 12 so that the plugging rod 10 is inserted into the stopping groove 7 on the stopping disc 6, restricting the rotation of the stopping disc 6 and also restricting the rotation of the winding drum 3, which can prevent the winding drum 3 from rotating automatically due to gravity and causing accidents. When the winding drum 3 needs to rotate, the first electromagnet 12 and the second electromagnet 13 are de-energized. The spring 14 resets and pushes the retaining ring 15 and the plugging rod 10, so that the upper end of the plugging rod 10 leaves the stopping groove 7 on the stopping disc 6 and slides on the surface of the stopping disc 6. The setting of the second ball 11 can make the plugging rod 10 slide more smoothly on the surface of the stopping disc 6.

[0027] Specifically, the limiting mechanism includes two third fixing seats 24, which are connected to the front end of the upper end surface of the bottom plate 1. A lead screw 26 is connected between the two third fixing seats 24. The left end of the lead screw 26 passes through the third fixing seat 24 and is connected to the second motor 25. A lead screw nut 29 is connected to the lead screw 26, and a limiting slider 28 is connected to the side wall of the lead screw nut 29. A chute 27 is opened on the upper end surface of the bottom plate 1 between the two third fixing seats 24, and the lower end of the limiting slider 28 is slidably connected in the chute 27. A hexagonal limiting ring 30 is connected to the side wall of the lead screw nut 29, and a ring groove 31 is opened on the inner side wall of the hexagonal limiting ring 30. A plurality of first balls 32 are movably connected in the ring groove 31. Both the ball groove and the second balls 11 are multiple. The cable on the reel 3 passes through the hexagonal limiting ring 30 for release or recovery. When releasing or recovering, the second motor 25 is started, and the second motor 25 drives the lead screw 26 to rotate, so that the lead screw nut 29 moves left and right on the lead screw 26. When the reel 3 rotates to recover the cable, the lead screw nut 29 moves from left to right on the lead screw 26. When it moves to the right end of the lead screw 26, the second motor 25 reverses to make the lead screw 26 move from right to left. In this way, the cable can be neatly laid on the reel 3, avoiding manual operation by workers and reducing the occurrence of dangerous accidents. A ring groove 31 is opened on the inner side wall of the hexagonal limiting ring 30, and a plurality of first balls 32 are movably connected in the ring groove 31. The cable can slide through the hexagonal limiting ring 30 more smoothly.

[0028] Working principle: Start the first motor 23. The first motor 23 drives the fourth gear 22 to rotate. The rotation of the fourth gear 22 drives the third gear 21 to rotate. The rotation of the third gear 21 drives the transmission shaft 19 to rotate. The rotation of the transmission shaft 19 drives the two second gears 18 to rotate. The rotation of the second gears 18 drives the gear belt 17, and the gear belt 17 drives the first gear 16 to rotate. The rotation of the first gear 16 drives the reel 3 to rotate, and the reel 3 can wind or release the cable; when the rotating shaft 5 on the reel 3 rotates, it drives the locking disk 6 to rotate. When the reel 3 stops rotating, the first electromagnet 12 and the second electromagnet 13 are energized. The second electromagnet 13 pushes the first electromagnet 12, so that the insertion rod 10 is inserted into the locking groove 7 on the locking disk 6, restricting the rotation of the locking disk 6 and also restricting the rotation of the reel 3, and can restrict the reel 3 from rotating automatically due to gravity; when the reel 3 needs to rotate, the first electromagnet 12 and the second electromagnet 13 are de-energized, and the spring 14 resets to push the retaining ring 15 and the insertion rod 10, so that the upper end of the insertion rod 10 leaves the locking groove 7 on the locking disk 6 and slides on the surface of the locking disk 6. The setting of the second ball 11 can make the insertion rod 10 slide more smoothly on the surface of the locking disk 6. The cable on the reel 3 passes through the hexagonal limit ring 30 for release or winding. When releasing or winding, the second motor 25 is started. The second motor 25 drives the lead screw 26 to rotate, so that the lead screw nut 29 moves left and right on the lead screw 26. When the reel 3 rotates to wind the cable, the lead screw nut 29 moves from left to right on the lead screw 26. When it moves to the right end of the lead screw 26, the second motor 25 reverses to make the lead screw 26 move from right to left, so that the cable can be neatly laid on the reel 3, avoiding manual operation by workers and reducing the occurrence of dangerous accidents; a ring groove 31 is formed on the inner side wall of the hexagonal limit ring 30, and a plurality of first balls 32 are movably connected in the ring groove 31. The cable can slide through the hexagonal limit ring 30 more smoothly.
