Description

Technical Field

[0001] This invention relates to the field of marine vessel equipment technology, and more specifically, to an anchor dropper for marine vessels. Background Technology

[0002] An anchor release device is a device on a ship used for emergency abandonment of anchor in case of sudden danger. There are various types of anchor release devices, including simple anchor release devices, helical anchor release devices, and latch-type anchor release devices. Their main function is to allow a ship to abandon anchor in an emergency when it is anchored at sea. One end of the anchor chain is connected to the anchor, while the other end is secured to the ship via the anchor release device. Normally, the anchor release device locks the end of the anchor chain in place. However, in an emergency requiring the abandonment of the anchor chain and anchor, the anchor chain is released by disengaging the anchor release device, and the anchor at its other end will detach from the ship.

[0003] However, most traditional ship anchor release devices are lateral locking structures, and quick unlocking is also achieved by moving the lateral locking structure to detach from the anchor chain. Since the anchor chain has strong tension during use, that is, the tension and friction between the anchor chain and the anchor release device are huge. There is a lack of structures that can reduce friction and unlock the anchor chain, so as to achieve the purpose of flexible and quick unlocking. At the same time, the existing technology lacks a structure that can protect the unlocking part. As a result, when the unlocking is not needed, it is impossible to prevent the unlocking part from being unlocked prematurely by external unstable factors, which leads to the situation where the anchor release device on the ship unlocks when it is not needed.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0025] Traditional ship anchor release devices are mostly lateral locking structures, and quick unlocking also involves moving this lateral locking structure to detach from the anchor chain. However, due to the strong tensile force of the anchor chain during use, the tensile and frictional forces between the anchor chain and the anchor release device are enormous. There is a lack of structures that can reduce friction and unlock the anchor chain, thus achieving flexible and rapid unlocking. To solve this problem, the following technical solution is proposed: Refer to the instruction manual appendix Figures 1-7 An anchor release device for marine vessels, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes an anchor release body 1. A hook 2 is rotatably mounted on one side of the anchor release body 1. The interior of the anchor release body 1 is provided with a rolling unlocking mechanism 3 and a pushing mechanism 4. The rolling unlocking mechanism 3 can rotate the structure that holds the hook 2 to a vacant position, and the hook 2 will then be released without restriction. The pushing mechanism 4 can simultaneously apply pressure to the outer wall of the hook 2 to push it out quickly. The top of the anchor release body 1 is provided with a locking and protecting mechanism 5. The locking and protecting mechanism 5 can wrap the unlocked structure and can be moved backward to expose the unlocked structure for use when needed.

[0026] like Figure 3 and Figure 4As shown, the rolling unlocking mechanism 3 includes a top rotating wheel 31 rotatably installed on the inner wall of the top of the anchor abandonment device body 1. The top rotating wheel 31 is set in a vertical state and is configured to cooperate with the hook 2. The outer wall of the top rotating wheel 31 is in contact with the outer wall of the hook 2. The inner wall of the top rotating wheel 31 is provided with a retraction groove 32. The area of ​​the retraction groove 32 is half the area of ​​the top rotating wheel 31, and the width of the retraction groove 32 is greater than the width of the hook 2. When the top rotating wheel 31 rotates, it rotates to the position of the hook 2 through the anti-resistance groove 32 on the top rotating wheel 31, so that the hook 2 can be disengaged and unlocked through the empty position of the anti-resistance groove 32.

[0027] like Figure 3 and Figure 4 As shown, two gears 33 are fixedly installed on the outer walls of the top rotating wheel 31. The two gears 33 are set in a vertical position. The bottom of the two gears 33 is engaged with a first toothed plate 34. The two first toothed plates 34 are slidably installed on the inner wall of the anchor abandoning device body 1. A push plate 35 is fixedly installed on one side of the two first toothed plates 34. The push plate 35 is slidably installed on the inner wall of the anchor abandoning device body 1. The push plate 35 drives the two first toothed plates 34 to move backward synchronously, and the two first toothed plates 34 push the shift gear 33 to rotate counterclockwise, that is, the shift gear 33 drives the top rotating wheel 31 to rotate.

[0028] like Figure 3 As shown, a connecting plate 36 is hinged to one side of the push plate 35, and a push block 37 is hinged to the other side of the connecting plate 36. A drag rod 38 is fixedly installed on one side of the push block 37. The drag rod 38 is rotatably installed on the inner wall of the anchor abandoner body 1. The drag rod 38 is set in a vertical state. A lever 39 is fixedly installed on the top of the drag rod 38. The lever 39 is set in a vertical state. A slot 310 is provided on the outer wall of the drag rod 38. The slot 310 is opened on one side of the anchor abandoner body 1. Pulling lever 39 causes drag rod 38 to rotate downwards, which in turn pulls push block 37 to move backwards in sync. Push block 37 then causes connecting plate 36 to move backwards in sync and push plate 35 to move in sync.

[0029] like Figure 3 and Figure 4 As shown, the pushing mechanism 4 includes a second toothed plate 41 meshing with the top of two gears 33. The two second toothed plates 41 are slidably installed on the top inner wall of the anchor abandonment body 1. The two second toothed plates 41 are arranged in a horizontal state. A sliding plate 42 is fixedly installed on one side of the two second toothed plates 41. A push rod 43 is fixedly installed at the bottom of the sliding plate 42. The push rod 43 is arranged in a vertical state. When the gears 33 on both sides rotate counterclockwise, they drive the second gear plate 41 to move forward. Then, the second gear plate 41 drives the sliding plate 42 and the push rod 43 to move synchronously.

[0030] like Figure 3 and Figure 4 As shown, a top support plate 44 is slidably installed on the bottom inner wall of the push rod 43. The top support plate 44 is set in a horizontal state. One side of the top support plate 44 is in contact with the outer wall of the hook 2. A support spring 45 is fixedly installed on the top of the top support plate 44. The support spring 45 is fixedly installed on the outer wall of the push rod 43. As the push rod 43 moves the top support plate 44 forward, the front end of the top support plate 44 presses against the outer wall of the hook 2. The forward movement of the push rod 43 compresses the support spring 45 at the top of the top support plate 44, causing the top support plate 44 to generate a forward thrust and be able to be quickly pushed out after the hook 2 is unlocked.

[0031] In practice, pulling the lever 39 causes the drag lever 38 to rotate downwards, which in turn causes the drag lever 38 to pull the push block 37 to move backwards synchronously. The push block 37 causes the connecting plate 36 to move backwards synchronously and the push plate 35 to move synchronously. The push plate 35 causes the two first toothed plates 34 to move backwards synchronously. The two first toothed plates 34 push the lever gear 33 to rotate counterclockwise. That is, the lever gear 33 drives the top rotating wheel 31 to rotate. When the top rotating wheel 31 rotates, it rotates to the position of the hook 2 through the anti-resistance groove 32 on the top rotating wheel 31, so that the hook 2 can be released and unlocked through the empty position of the anti-resistance groove 32. Thus, the friction between the rotating top rotating wheel 31 and the hook 2 is reduced, so that it can be unlocked flexibly and quickly. When the gears 33 on both sides rotate counterclockwise, they drive the second toothed plate 41 to move forward. The second toothed plate 41 then drives the sliding plate 42 and the push rod 43 to move synchronously. The push rod 43 drives the top support plate 44 to move forward. The front end of the top support plate 44 presses against the outer wall of the hook 2. The forward movement of the push rod 43 compresses the support spring 45 at the top of the top support plate 44, so that the top support plate 44 generates a forward thrust and can be quickly pushed out after the hook 2 is unlocked. Example 2

[0032] Existing technologies lack structures to protect the unlocking mechanism, making it impossible to prevent premature unlocking due to external instability when the unlocking is not needed. This results in the anchor release device on ships unlocking when not in use. To address this issue, the following technical solution is proposed: like Figure 5 and Figure 6 As shown, the clamping mechanism 5 includes a clamping cover plate 51 that is slidably installed on the top outer wall of the anchor abandoner body 1. The clamping cover plate 51 is set in a vertical state and covers the outer wall of the lever 39. The area of ​​the clamping cover plate 51 is larger than the area of ​​the lever 39. Sliding rods 52 are fixedly installed on both sides of the clamping cover plate 51. The two sliding rods 52 are slidably installed on the inner wall of the anchor abandoner body 1. Limiting springs 53 are fixedly installed on the outer walls of both sides of the clamping cover plate 51. The limiting springs 53 are fixedly installed on the outer wall of the anchor abandoner body 1. The cover plate 51 protects the outer wall of the lever 39, and pushes the cover plate 51 to move backward. The cover plate 51 drives the slide bar 52 to move backward on the outer wall of the anchor abandonment device body 1 and compresses the limiting spring 53.

[0033] like Figure 7 As shown, a top support plate 54 is provided on one side of the cover plate 51. The top support plate 54 is rotatably installed on the top of the anchor abandoner body 1. The top support plate 54 is set in a horizontal state. The outer wall of the top support plate 54 is in contact with the outer wall of the cover plate 51. A bottom support plate 55 is provided at the bottom of the top support plate 54. The bottom support plate 55 is fixedly installed on the top outer wall of the anchor abandoner body 1. A pull ring 56 is fixedly installed on the top of the top support plate 54. The top support plate 54 is kept horizontal by the bottom support plate 55 and presses against the rear side of the cover plate 51, thereby keeping the cover plate 51 stable. The top support plate 54 can be pulled up and rotated upward by the pull ring 56.

[0034] In specific implementation, the top support plate 54 is kept horizontal by the bottom support plate 55 and presses against the rear side of the cover plate 51, thereby keeping the cover plate 51 stable. The cover plate 51 protects the outer wall of the lever 39 and prevents the lever 39 and the drag bar 38 from being prematurely rotated downwards and unlocked due to external unstable factors. Pulling the top support plate 54 upwards via the pull ring 56 allows the cover plate 51 to move. Pushing the cover plate 51 backwards causes the slide bar 52 to move backwards on the outer wall of the anchor abandonment device body 1 and compress the limiting spring 53, allowing the lever 39 and the drag bar 38 to be exposed and rotated.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
