Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine equipment technology, and in particular to a quick anchoring and dropping device that is easy to operate. Background Technology
[0002] Anchoring equipment is a device on a ship used for dropping (anchoring) and retrieving (raising) the anchor. Its main function is to ensure that the ship remains stably anchored in a designated position while moored, preventing it from drifting due to external forces such as currents and waves. During anchoring, the equipment releases the anchor and anchor chain at an appropriate speed and in a suitable manner, allowing the anchor to sink smoothly to the seabed and hold firmly. Raising the anchor involves pulling the anchor from the seabed and retrieving the anchor chain into the ship's anchor chain hold.
[0003] Current anchor-laying equipment may experience chain accumulation or entanglement during the chain deployment and retrieval process, making it difficult to accurately control the chain and posing significant safety hazards. Chain entanglement can lead to jamming, overloading the anchor winch, and causing malfunctions such as motor burnout or damage to mechanical components. Utility Model Content
[0004] The present invention aims to provide an easy-to-operate and rapid anchor launching and throwing device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An easy-to-operate, rapid anchor-raising and throwing device includes a base, a bracket connected to the base, a rotating shaft rotatably connected to the bracket, a winding drum connected to the rotating shaft, a baffle connected to the winding drum, a second bracket connected to the base, a rotating shaft rotatably connected to the second bracket, a sprocket connected to the rotating shaft, a motor connected to the second bracket, the output end of the motor connected to the rotating shaft, a pulley assembly connected to both the rotating shaft and the rotating shaft, a sliding groove on the base, a reciprocating screw rotatably connected to the base, a second motor connected to the base, the output end of the second motor connected to the reciprocating screw, a slider connected to the reciprocating screw, a sliding connection between the slider and the sliding groove, a moving column connected to the slider, a through groove on the moving column, a limit device connected to the moving column, a support column connected to the base, and a guide cylinder connected to the support column.
[0007] Preferably, the limiting device includes a locking block, the movable column has a hidden groove that communicates with a through groove, the movable column is slidably connected to a connecting rod, the connecting rod is connected to a handle, the other end of the connecting rod is connected to the locking block, a spring is sleeved on the outside of the connecting rod, the two ends of the spring are respectively connected to the inner wall of the hidden groove and the locking block, and a limiting sleeve is engaged on the outside of the connecting rod.
[0008] Preferably, the second rotating shaft is connected to a protective plate.
[0009] Preferably, the guide cylinder is connected to a water inlet pipe.
[0010] Preferably, the guide cylinder is connected to brush bristles.
[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:
[0012] (1) This technical solution, by setting up a winding drum and baffles, can wind up the anchor chain, preventing it from being randomly piled up on the deck. This allows the space occupied by the anchor chain to be more organized, freeing up more usable space for cargo storage, equipment installation, or expansion of the crew's living area. Furthermore, it enables the anchor chain to be released and retrieved quickly and orderly, reducing preparation time for anchoring operations and improving the ship's operational efficiency. By setting up reciprocating screws, sliders, moving posts, and through holes, the direction of the anchor chain can be changed, allowing it to be wound regularly around the outside of the winding drum. This avoids the anchor chain piling up and tangling in one place on the winding drum, ensuring that the anchor chain is evenly distributed along the entire length of the winding drum. This reduces the possibility of the anchor chain crossing or knotting during winding, ensuring the stable operation of the anchoring equipment, reducing the time spent on maintenance due to malfunctions, and improving overall work efficiency.
[0013] (2) By setting hidden grooves, connecting columns, springs and locking blocks, the displacement of the anchor chain can be limited, ensuring that the load of the motor is always within a safe range, effectively extending the service life of the motor, and ensuring the stable operation of the entire anchor throwing equipment.
[0014] (3) By setting up a protective plate, the lateral movement of the anchor chain can be restricted, ensuring that the anchor chain is always stably engaged with the sprocket, avoiding the interruption of anchoring and throwing due to the anchor chain falling off, maintaining the normal operation of the anchoring and throwing equipment, and ensuring the safe berthing and departure of the ship.
[0015] (4) By installing a water inlet pipe, most of the mud and sand brought from the seabed on the anchor chain can be washed away. By installing bristles, the anchor chain can be deeply cleaned. The bristles can penetrate into the gaps of the anchor chain links to remove the attached dirt, mud, sand, and marine organisms. This reduces the friction between the sprocket teeth and the anchor chain links, extending the service life of the equipment. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0022] like Figure 1-4The illustrated easy-to-operate, rapid anchor-laying device includes a base 1. Two sets of brackets 2 are connected to the upper surface of the base 1. The two sets of brackets 2 are rotatably connected to a rotating shaft 4. A winding drum 17 is connected to the rotating shaft 4, and baffles 3 are connected to both ends of the winding drum 17. Two sets of brackets 15 are also connected to the upper surface of the base 1. These two sets of brackets 15 are rotatably connected to a rotating shaft 11. A sprocket 19 is connected to the rotating shaft 11, and two sets of protective plates 10 are connected to the rotating shaft 11, located on either side of the sprocket 19. A motor 24 is connected to any one of the brackets 15. The output end of the motor 24 is connected to one end of the rotating shaft 11, and the other end of the rotating shaft 11 and the rotating shaft 4 are connected to a pulley assembly 5. The top wall of base 1 has a groove 20. A reciprocating screw 21 is rotatably connected to base 1, passing through the groove 20. A second motor 16 is connected to the front wall of base 1, and the output end of the second motor 16 is connected to the reciprocating screw 21. A slider 22 is connected to the reciprocating screw 21, and the slider 22 is slidably connected to the groove 20. When the reciprocating screw 21 rotates, the slider 22 reciprocates along the reciprocating screw 21 under the constraint of the groove 20. A moving column 6 is connected to the top wall of the slider 22, and the moving column 6 has a through groove 18. When the first motor 24 is turned on, its output end drives the second rotating shaft 11 to rotate, thereby causing the sprocket 19 connected to the second rotating shaft 11 to rotate. Since two sets of protective plates 10 are connected to the second rotating shaft 11, the protective plates 10 can prevent the anchor chain from falling off from both sides of the sprocket 19, ensuring the normal meshing of the anchor chain and the sprocket 19. While motor 24 drives shaft 11 to rotate, it transmits power to shaft 4 via pulley assembly 5, causing shaft 4 to rotate as well, which in turn drives the winding drum 17 to rotate. The baffles 3 at both ends of the winding drum 17 prevent the anchor chain from slipping off during winding. After motor 26 starts, its output drives the reciprocating screw 21 to rotate. Because the base 1 has a groove 20, the reciprocating screw 21 passes through the groove 20, and the slider 22 is slidably connected to the groove 20. Under the constraint of the groove 20, the slider 22 can only reciprocate along the reciprocating screw 21. The moving column 6 connected to the top wall of the slider 22 has a through groove 18, through which the anchor chain passes. As the slider 22 reciprocates, the moving column 6 also moves left and right accordingly, thus changing the direction of the anchor chain and allowing it to be wound regularly around the outside of the winding drum 17.
[0023] like Figure 2 , Figure 4As shown, the movable column 6 is connected to a limiting device. The limiting device includes a locking block 27. The movable column 6 has a hidden groove 26, which is located above and communicates with the through groove 18. A connecting rod 8 is slidably connected to the top of the movable column 6. One end of the connecting rod 8, located inside the hidden groove 26, is connected to the locking block 27. A spring 25 is sleeved on the outside of the connecting rod 8, and both ends of the spring 25 are connected to the inner wall of the hidden groove 26 and the locking block 27, respectively. A handle 7 is connected to the outside end of the connecting rod 8. A limiting sleeve 9 is engaged on the outside of the connecting rod 8. The side wall of the limiting sleeve 9 has an opening, and both ends of the limiting sleeve 9 abut against the handle 7 and the movable column 6, respectively. When the limiting sleeve 9 is engaged with the connecting rod 8, the locking block 27 is completely located inside the hidden groove 26. At this time, the limiting device is in a ready-to-work state and will not obstruct the normal unwinding and rewinding operations of the anchor chain. The side of the locking block 27 near the winding drum 17 is a vertical surface, and the side of the locking block 27 near the sprocket 19 is an arc surface. When the limiting sleeve 9 is removed from the connecting rod 8, the spring 25 presses against the locking block 27, causing the locking block 27 to insert into the gap of the anchor chain. The anchor chain contacts the perpendicular side of the locking block 27, preventing the sprocket 19 from moving and thus preventing the anchor chain from lengthening. When winding, the anchor chain can press the locking block 27 upward along the arc, allowing the anchor chain to move towards the winding drum 17 without affecting the winding of the anchor chain.
[0024] like Figure 2 As shown, a support column 12 is connected to the base 1, and a guide cylinder 14 is connected to the support column 12. A water inlet pipe 13 is connected to the top of the guide cylinder 14, and brush bristles 23 are connected to the inner wall of the guide cylinder 14. When the anchor chain passes through the guide cylinder 14 during the extension and retraction process, the water inlet pipe 13 connected to the top of the guide cylinder 14 sprays water onto the anchor chain to rinse it, effectively washing away most of the mud and sand and other dirt brought from the bottom of the water. The brush bristles 23 connected to the inner wall of the guide cylinder 14 come into contact with the anchor chain, and while the water is rinsing, the brush bristles 23 wipe the anchor chain, further enhancing the cleaning effect and thoroughly removing dirt from the surface of the anchor chain and the gaps between the chain links.
[0025] The specific implementation process is as follows:
[0026] The free end of the anchor chain passes through the guide sleeve, engages with the sprocket 19, and then winds around the outside of the winding drum 17 through the through hole. When anchoring, motor 24 is started, driving shaft 11 to rotate, which in turn rotates the sprocket 19. Simultaneously, the pulley assembly 5 drives the winding drum 17 to rotate in reverse, gradually lowering the anchor chain wound around the outside of the winding drum 17 to the seabed. When lifting the anchor, the limiting sleeve 9 on the outside of the connecting rod 8 is removed, allowing the locking block 27 to drop. Motor 24 is started in reverse, causing the sprocket 19 and winding drum 17 to rotate forward, beginning the retrieval of the anchor chain. Motor 16 is started to control the direction of the anchor chain, ensuring it is wound regularly around the winding drum 17. During the lifting process, the water inlet pipe 13 of the guide drum 14 is connected to a water source for spraying water, and the brush 23 wipes the retrieved anchor chain.
