Description
Technical Field
[0001] The present invention relates to the technical field of fishing vessel mooring, and in particular to an auxiliary device used for mooring fishing vessels. Background Art
[0002] Mooring of fishing vessels means that when a fishing vessel stays at sea or in a port, a mooring device is used to fix the vessel in a designated position to prevent the vessel from drifting or being affected by external forces. This mooring method is very common in daily operations, sheltering from the wind, and waiting situations of fishing vessels. Mooring is to fix the vessel at each specific position by using equipment such as ship cables, anchor chains or mooring piles. Mooring is a common technical means for ships to dock in ports, fishing grounds, safe havens and other sea areas, and is usually used for small and medium-sized civilian fishing vessels.
[0003] The most common mooring device is the mooring pile. The staff puts the cable on the ship onto the mooring pile in the port and then moors the ship at a single point through the cable. The operation is simple and convenient, but there are still the following problems: when the staff puts the cable on the mooring pile, it can be easily put on because there is no tension in the cable. However, when the staff want to remove the cable, the cable is pulled by the fishing boat, resulting in a high tension, and it is difficult for the staff to remove it manually. Moreover, if the cable is forcibly removed, the tension originally stored in the cable will be released instantly. Since the cable itself is elastic, the impact force generated after the release causes the cable to rebound or swing quickly, posing a safety hazard to surrounding personnel. Summary of the Invention
[0004] In view of the problems in the prior art that it is difficult for personnel to remove the cable and that the tension of the cable may cause safety hazards during removal, an auxiliary device for mooring fishing vessels is proposed.
[0005] The present application provides an auxiliary device for mooring fishing vessels, which aims to provide an automatic rope loosening unit. When a worker needs to remove a cable sleeved on a mooring pile, the worker can control a hydraulic cylinder so that the hydraulic cylinder can drive the cable pile to move downward in a vertical direction. During the movement, an unlocking component presses a metal rod into the cable pile so as not to affect the cable, and continues to move downward, so that a push ring limits the lower part of the cable. As the cable pile continues to move downward, the push ring can push the cable onto the special-shaped pile, and the special-shaped pile can eliminate the cable tension and remove the cable from the cable pile, thereby realizing automation while reducing safety hazards.
[0006] The technical solution of the present invention is: an auxiliary device for mooring fishing boats, comprising a dock and a cable, a sliding groove provided on the dock surface, a bollard slidably disposed in the sliding groove, and an automatic rope release unit provided on the bollard, the automatic rope release unit comprising a pushing component provided on the bollard and an unlocking component inside the bollard; The pushing component includes a special-shaped pile arranged at the upper end of the bollard, a bearing block arranged at the upper end of the dock, a circular ring sleeve arranged at the upper end of the bearing block, a pushing ring arranged inside the circular ring sleeve, and a compression spring arranged between the pushing ring and the inner wall of the circular ring sleeve. The pushing ring is used to push the cable out of the bollard; The special-shaped pile includes an elimination area, a buffer area, and a separation area. The elimination area is used to eliminate the tension of the cable, the buffer area is used to buffer for a period of time after eliminating the pressure, and the separation area is used to cooperate with the pushing ring to push the cable out of the bollard.
[0007] Furthermore, the unlocking component includes a square groove opened on the side wall of the bollard, a metal rod arranged in the square groove, a mounting plate arranged at one end of the metal rod, a cavity opened inside the bollard, a fixing groove opened on the inner wall of the cavity, and a strong spring arranged between the mounting plate and the inner wall of the fixing groove.
[0008] Furthermore, the cable is sleeved on the bollard. The cable is located between the metal rod and the pushing ring. The metal rod and the pushing ring are used to limit the cable to prevent the cable from detaching from the bollard under the action of strong pulling force.
[0009] Furthermore, a trigger rod is slidably installed inside the bollard. A limit disk is fixedly installed at the upper end of the trigger rod. The distance between the limit disk and the bottom end of the cavity is H. A driving component is arranged at the lower end of the trigger rod. A cooperation component is installed between the limit disk and the metal rod.
[0010] Furthermore, the driving component includes an empty groove opened inside the dock, a connecting plate arranged at the lower end of the trigger rod, a telescopic rod arranged at the lower end of the connecting plate, a hydraulic cylinder arranged at the lower end of the telescopic rod, and the lower end of the telescopic rod is fixedly connected to the telescopic end of the hydraulic cylinder.
[0011] Furthermore, the cooperation component includes a lifting plate arranged at the upper end of the limit disk, a trapezoidal block arranged at the upper end of the lifting plate, and a cooperation groove opened on the metal rod. The lifting plate and the trapezoidal block are both located inside the cooperation groove.
[0012] Furthermore, the vertical height of the trapezoidal block is H, and the horizontal length of the trapezoidal block is equal to the length of the metal rod exposed outside the bollard wall.
[0013] Furthermore, a waterproof box is installed inside the empty groove. The hydraulic cylinder is located inside the waterproof box. The waterproof box is used to protect the hydraulic cylinder to prevent the hydraulic cylinder from being damaged by water ingress.
[0014] The beneficial effects of the present invention: By setting up the unlocking component, when the cable is sleeved on the bollard, the metal rod extends out and cooperates with the push ring. The cable is located between the two and is limited, which can effectively prevent the situation that the sleeved cable separates from the bollard due to the shaking of the fishing boat during mooring. When the staff needs to take out the cable, during the process that the trigger rod moves downward by a distance of H, the metal rod is squeezed into the inner wall of the bollard through the cooperation component to release the limitation of the metal rod on the cable, so as to prepare for the subsequent taking out of the cable.
[0015] By setting up the pushing component, after the metal rod is inside the bollard, the trigger rod continues to move downward and drives the bollard to move downward synchronously through the limiting disk. Relative movement occurs between the bollard and the push ring, and the push ring limits the lower part of the cable, so that the cable cannot move downward synchronously with the bollard. Therefore, the cable also moves upward relative to the bollard. When the cable moves upward along the bollard and the special-shaped pile, the cable first moves relatively to the elimination area on the special-shaped pile, and during the movement, the cable generates a pulling force on the fishing boat, making the fishing boat approach the bollard by a certain distance. Subsequently, the cable continues to move relatively to the buffer area, so that the fishing boat has enough time to approach the bollard. When the fishing boat approaches the bollard, the cable continues to move relatively upward to the release area, and the release area gradually reduces the tension of the cable, making the cable in a relaxed state. When the cable moves out of the release area, the cable is taken out of the bollard in a relaxed state, thus completing the taking out of the cable.
[0016] By setting up the automatic cable loosening unit, the cable can be automatically taken out from the bollard without manual operation throughout the process, reducing the workload of the staff. Moreover, before taking out the cable, the automatic cable loosening unit can effectively eliminate the tension on the cable, thereby effectively reducing the safety risk during cable taking out and improving the safety of the surrounding staff.

[0019] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.
[0020] Example 1, referring to Figures 1-5 , which is the first embodiment of the present invention, provides an auxiliary device for fishing boat docking and mooring, including a wharf 1 and a cable 9, a sliding groove 2 opened on the surface of the wharf 1, a bollard 3 slidably installed in the sliding groove 2, and an automatic rope loosening unit installed on the bollard 3. The automatic rope loosening unit includes a pushing component installed on the bollard 3 and an unlocking component inside the bollard 3.
[0021] The pushing component includes a special-shaped pile 4 fixedly installed at the upper end of the bollard 3, a bearing block 5 fixedly installed at the upper end of the wharf 1, a ring sleeve 6 fixedly installed at the upper end of the bearing block 5, a push ring 7 slidably installed in the ring sleeve 6, an extrusion spring 8 fixedly installed between the push ring 7 and the inner wall of the ring sleeve 6, and the push ring 7 is used to push the cable 9 out of the bollard 3.
[0022] Referring to Figure 8 , the special-shaped pile 4 includes an elimination area 10, a buffer area 11 and a detachment area 12. The elimination area 10 is used to eliminate the tension of the cable 9, the buffer area 11 is used for buffering for a period of time after eliminating the pressure, and the detachment area 12 is used to cooperate with the push ring 7 to push the cable 9 out of the bollard 3.
[0023] Referring to Figure 8 and Figure 9, The cable 9 is sleeved on the bollard 3. The cable 9 is located between the metal rod 13 and the push ring 7. The metal rod 13 and the push ring 7 are used to limit the cable 9 to prevent the cable 9 from detaching from the bollard 3 under the action of strong tension. A trigger rod 18 is slidably installed inside the bollard 3. A limit disk 19 is fixedly installed at the upper end of the trigger rod 18. The distance between the limit disk 19 and the bottom end of the cavity 15 is H. A driving component is installed at the lower end of the trigger rod 18, and a matching component is installed between the limit disk 19 and the metal rod 13. The driving component includes an empty slot 20 opened inside the dock 1, a connecting plate 21 fixedly installed at the lower end of the trigger rod 18, a telescopic rod 22 fixedly installed at the lower end of the connecting plate 21, a hydraulic cylinder 23 fixedly installed at the lower end of the telescopic rod 22, and the lower end of the telescopic rod 22 is fixedly connected to the telescopic end of the hydraulic cylinder 23.
[0024] Specifically, the pushing component is used to automatically push out the cable 9 sleeved on the bollard 3, thereby realizing the operation without manual labor. And by setting the special-shaped pile 4, before the cable 9 is taken out, the possible tension of the cable 9 is eliminated, thereby ensuring the safety during the taking-out process. The specific working principle is as follows: The driving component drives the bollard 3 to move downward in the vertical direction through the telescopic end of the hydraulic cylinder 23. During the downward movement of the bollard 3, the push ring 7 remains stationary. This causes the push ring 7 to move upward relative to the bollard 3. And since the push ring 7 is located at the lower end of the cable 9, when the bollard 3 moves downward, the push ring 7 limits the cable 9, causing the cable 9 to move upward relative to the bollard 3. During the relative upward movement of the cable 9, it will move upward from the surface of the bollard 3 and move onto the special-shaped pile 4. The specific movement process and the resulting effects are as follows: When the bollard 3 moves downward, the cable 9 first enters the elimination area 10 (the elimination area 10 is used to eliminate the tension in the cable 9 to prepare for the subsequent taking-out of the cable 9). The elimination area 10 of the special-shaped pile 4 has a continuously increasing radius from bottom to top (refer to L1 in Figure 8 ). When the cable 9 moves in the elimination area 10, due to the continuously increasing radius of the elimination area 10 and at the same time under the thrust of the push ring 7, the cable 9 moves outward in the horizontal direction, causing the tension of the cable 9 to increase first and pulling the fishing boat to move along the horizontal direction. During the movement of the fishing boat along the horizontal direction, it will continue to move a certain distance under the action of inertia, making the distance between the fishing boat and the bollard 3 less than the length of the cable 9. At this time, the cable 9 is in a relaxed state and there is no or less tension inside it.
[0025] When the cable 9 moves from the elimination area 10 to the buffer area 11, the tension is first eliminated. The radius of the buffer area 11 of the special-shaped pile 4 remains unchanged (refer to L2 in Figure 8 ). At this time, during the movement of the cable 9 in the buffer area 11, the tension of the cable 9 will not change, and the buffer area 11 is used to give the fishing boat enough time during the movement to eliminate the tension in the cable 9. After the cable 9 enters the detachment area 12, since the radius of the detachment area 12 continuously decreases (refer to Figure 8 L3 in
[0026] ), at this time, the cable 9 gradually detaches from the special-shaped pile 4 during the movement. When it moves to the final point of the detachment area 12, the cable 9 is completely separated from the special-shaped pile 4. At this time, the staff can take in the cable 9 to complete the removal of the cable 9. Figures 5-7 Embodiment 2, refer to
[0027] , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the unlocking component includes a square groove opened on the side wall of the cable pile 3, a metal rod 13 slidably installed in the square groove, a mounting plate 14 fixedly installed at one end of the metal rod 13, a cavity 15 opened inside the cable pile 3, a fixing groove 16 opened on the inner wall of the cavity 15, and a strong spring 17 fixedly installed between the mounting plate 14 and the inner wall of the fixing groove 16. The matching component includes a lifting plate 24 fixedly installed at the upper end of the limiting plate 19, a trapezoidal block 25 fixedly installed at the upper end of the lifting plate 24, a matching groove 26 opened on the metal rod 13, and both the lifting plate 24 and the trapezoidal block 25 are located in the matching groove 26. The vertical height of the trapezoidal block 25 is H, and the horizontal length of the trapezoidal block 25 is equal to the length of the metal rod 13 exposed outside the outer wall of the cable pile 3.
[0028] During use, when the staff needs to take out the cable 9, the hydraulic cylinder 23 is activated. The telescopic end of the hydraulic cylinder 23 drives the limit disk 19 to move downward through the trigger rod 18. When the limit disk 19 moves downward by a distance H, the limit disk 19 will drive the upper lifting plate 24 to move synchronously, and will not drive the trigger rod 18 to move downward. During the downward movement of the limit disk 19, the lifting plate 24 drives the trapezoidal block 25 to move synchronously. When the trapezoidal block 25 moves downward, it cooperates with the mating groove 26 to generate a horizontal pressure on the metal rod 13. Then, under the action of the pressure, the metal rod 13 moves horizontally inward until the metal rod 13 completely enters the cable pile 3. After the metal rod 13 enters the cable pile 3, the limit disk 19 contacts the bottom end of the cavity 15. At this time, when the limit disk 19 continues to move downward, it will drive the entire cable pile 3 to move downward.
[0029] The remaining structure is the same as that of Embodiment 1.
[0030] Embodiment 3, referring to Figures 2-3 , is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a waterproof box is installed inside the empty groove 20, and the hydraulic cylinder 23 is located inside the waterproof box. The waterproof box is used to protect the hydraulic cylinder 23 to prevent the hydraulic cylinder 23 from being damaged by water ingress.
[0031] Specifically, since the periphery of the dock 1 is all seawater, and if the staff wants to control the hydraulic cylinder 23, a controller and sensors need to be set inside the hydraulic cylinder 23. To prevent the electronic components from coming into direct contact with seawater and causing corrosion and damage to the internal components, a waterproof box is set to protect the hydraulic cylinder 23 and the electronic components, so as to improve the service life of the device.
[0032] The remaining structure is the same as that of Embodiment 2.
[0033] Combining Embodiments 1-3, the working principle of the present invention is as follows: When the staff needs to take out the cable 9, the hydraulic cylinder 23 is activated. The telescopic end of the hydraulic cylinder 23 drives the limit disk 19 to move downward through the trigger rod 18. When the limit disk 19 moves downward by a distance H, the limit disk 19 will drive the upper lifting plate 24 to move synchronously, and will not drive the trigger rod 18 to move downward. During the downward movement of the limit disk 19, the lifting plate 24 drives the trapezoidal block 25 to move synchronously. When the trapezoidal block 25 moves downward, it cooperates with the mating groove 26 to generate a horizontal pressure on the metal rod 13. Then, under the action of the pressure, the metal rod 13 moves horizontally inward until the metal rod 13 completely enters the cable pile 3. After the metal rod 13 enters the cable pile 3, the limit disk 19 contacts the bottom end of the cavity 15. At this time, when the limit disk 19 continues to move downward, it will drive the entire cable pile 3 to move downward.
[0034] When the bollard 3 moves downward, the cable 9 first enters the elimination area 10 under the thrust of the pushing ring 7 (the elimination area 10 is used to eliminate the tension in the cable 9 to prepare for the subsequent removal of the cable 9). The radius of the elimination area 10 of the special-shaped pile 4 increases continuously from bottom to top (refer to Figure 8 L1 in
[0035] ). When the cable 9 moves in the elimination area 10, due to the continuously increasing radius of the elimination area 10 and the thrust of the pushing ring 7 on the cable 9, the cable 9 moves outward in the horizontal direction, causing the tension of the cable 9 to increase first and pulling the fishing boat to move horizontally. During the horizontal movement of the fishing boat, it will continue to move a certain distance under the action of inertia, making the distance between the fishing boat and the bollard 3 less than the length of the cable 9. At this time, the cable 9 is in a relaxed state, and there is no or little tension inside it. Figure 8 When the cable 9 moves from the elimination area 10 to the buffer area 11, the tension is first eliminated. The radius of the buffer area 11 of the special-shaped pile 4 remains unchanged (refer to L2 in Figure 8 ). At this time, during the movement of the cable 9 in the buffer area 11, the tension of the cable 9 will not be changed, and the buffer area 11 is used to give the fishing boat enough time during the movement to eliminate the tension in the cable 9.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
