Description

Technical Field

[0001] The present invention relates to the field of ships, and in particular to a ship anchoring device based on intelligent hydraulic drive. Background Art

[0002] Traditional hydraulic anchoring systems achieve efficient anchor retraction and deployment. However, during this process, the anchor chain may not be stable enough, compromising anchoring effectiveness. Furthermore, if the anchor is not properly secured while sailing, the vessel's swaying can cause collision with the hull. This can damage the anchor and hull over time and potentially compromise navigation safety.

[0003] The anchor fixing device and ship currently disclosed in China with the authorization announcement number CN116902138B include a fixing box, the top of which is provided with a connecting hole, the anchor chain passes through the connecting hole and is connected to the winding device on the hull, the bottom end of the fixing box is provided with a storage hole for the anchor body to enter the fixing box, the fixing box is provided with a removable clamping member, the anchor body can be clamped and fixed in the fixing box by the clamping member, the top end of the fixing box is rotatably provided with a guide wheel, the clamping member includes a first spring and a clamping plate arranged at the end of the first spring, the first spring is used to push the clamping plate to clamp the anchor body, and a driving component is also provided in the fixing box, which can drive the clamping plate to compress or release the first spring, and there are two clamping plates opposite to each other in the fixing box.

[0004] According to the above-mentioned patent, the patent can clamp the anchor body through the clamping parts in the fixing box, so that the anchor will not collide with the hull, and the clamping parts can also prevent the anchor body from shaking randomly. At the same time, the winding of the anchor chain can be guided by the guide wheel, so that the winding operation of the anchor chain is smoother and more reliable. However, during long-term use, the first spring in the clamping part may lose its original elastic force due to fatigue, resulting in the clamping plate being unable to effectively fix the anchor body, thereby affecting reliability. In addition, in the process of lowering the anchor body, the lowering speed is too fast and it is easy to cause the anchor chain to break or physical damage to the anchor itself. Therefore, there is a need for a ship anchoring device based on intelligent hydraulic drive that can realize the smooth lowering and recovery of the anchor chain, ensure the stability of the anchor body when not in use, and prevent it from colliding with the hull and shaking randomly. Summary of the Invention

[0005] In response to the problems existing in the existing technology, a ship anchoring device based on intelligent hydraulic drive is provided. Through the coordinated use of guide wheels and clamps, speed control and firm locking of the anchor during lowering and recovery are achieved, reducing the risk of sudden impact when lowering the anchor and ensuring that the position of the anchor remains fixed when it is retrieved, preventing accidental collisions.

[0006] In order to solve the problems of the prior art, the present invention provides a ship anchoring device based on intelligent hydraulic drive, including a frame, wherein the frame is provided with a hydraulic drive mechanism for driving the anchor chain to retract and release the anchor, and the frame is also provided with a stabilizing mechanism for keeping the anchor stably retracted and released, the stabilizing mechanism including guide wheels symmetrically arranged on both sides of the anchor chain and a locking structure that cooperates with the two guide wheels and can fix the anchor, each of the guide wheels can move on the frame toward the direction of the anchor chain, and each guide wheel is provided with a rubber ring, when the two guide wheels approach each other and squeeze the anchor chain, the lowering of the anchor is in a deceleration state, and the locking structure remains in an unlocked state, and when the two guide wheels move away from each other and do not squeeze the anchor chain, the retraction of the anchor is in a uniform speed state, and the locking structure remains in a state to be self-locked.

[0007] Preferably, the locking structure has clamps symmetrically arranged on both sides of the anchor chain and located below the guide wheel, each of the clamps can be moved on the frame toward the anchor, and when the anchor is clamped between the two clamps, the anchor is in a locked state, so that the anchor remains stable relative to the ship.

[0008] Preferably, the locking structure further comprises an anchor rod provided on the anchor and with both ends extending towards each cleat respectively, and each cleat is provided with a slot in which the corresponding end of the anchor rod can be clamped.

[0009] Preferably, the slots formed in each clamping plate are provided with a rubber layer capable of buffering the squeezing force of the clamping plate on the end of the anchor rod and increasing the friction force.

[0010] Preferably, a slider is provided on the frame for each splint to be rotatably connected thereto, and the slider is provided with an elastic member that can press the splint inward. The inner side of the lower end of each splint also has a slope. When the end of the anchor rod passes through the splint along the slope, the splint is pushed to rotate outward, and the elastic member is in a compressed state.

[0011] Preferably, both ends of the anchor rod are spherical structures, and the rubber layer on each splint has a notch into which the anchor rod end can be embedded. When the splint is pressed and reset, the anchor rod end sinks into the notch on the rubber layer and is in a wrapped state.

[0012] Preferably, a stopper is provided on the frame for stopping the slider from continuing to move inward. When the two sliders are in contact with the corresponding stoppers respectively, the two clamping plates are in a state to be self-locked, forming a self-locking area.

[0013] Preferably, an elastic clamp capable of adaptively clamping the anchor rod is provided on the frame, the elastic clamp has a guide edge for guiding the anchor rod into it, and the elastic clamp and the clamping plate together form the self-locking area for horizontally and vertically limiting the anchor.

[0014] Preferably, the frame is provided with a hydraulic cylinder that cooperates with the hydraulic drive mechanism to synchronously drive the two guide wheels to move relative to each other, and a first linkage member is provided between the working end of the hydraulic cylinder and each guide wheel.

[0015] Preferably, a second linkage is provided between the working end of the hydraulic cylinder and the slider. When the guide wheel is driven closer to or away from the anchor chain, the slider moves synchronously outward or inward under the drive of the second linkage, so that the splint moves away from or closer to the anchor.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The present invention achieves speed control and improved stability during the anchor lowering and recovery process by enabling the guide wheels arranged on both sides of the anchor chain to move precisely in the direction of the anchor chain.

[0018] When it is necessary to slow down the lowering of the anchor, the two guide wheels move closer to each other, gradually squeezing the anchor chain in the middle. As the distance between the guide wheels decreases, the pressure applied to the anchor chain increases, causing the anchor chain to move at a slower speed, thereby achieving a smooth and decelerated lowering of the anchor.

[0019] Conversely, when retrieving the anchor, the guide wheels move away from each other, no longer squeezing the anchor chain, allowing it to be quickly and evenly pulled back onto the vessel with minimal resistance. This not only ensures smooth operation of the anchor chain, but also effectively reduces the risks associated with sudden impacts or excessively rapid lowering, significantly improving the safety and reliability of the ship's mooring.

[0020] 2. The present invention enables the clamping plates located on both sides of the anchor chain to move inward on the frame and accurately clamp the anchor chain, thereby achieving effective locking and firm fixation of the anchor.

[0021] As the cleat gradually approaches and finally grips the anchor chain, the two ends of the anchor rod align and enter the grooves on the cleat. As the cleat closes, the ends of the anchor rod are firmly locked in the grooves with the rubber layer, ensuring that the anchor is firmly locked. The rubber layer increases the friction between the anchor rod and the cleat, preventing the anchor rod from loosening or slipping due to vibration or other external forces.

[0022] Furthermore, the clamping plate slides to a predetermined position on the frame via a slider and automatically locks the anchor rod with the help of an elastic member. This not only enhances the stability of the locking structure and effectively prevents the anchor from accidentally loosening or sliding, but also improves the safety and reliability of the ship in various sea conditions, ensuring that the anchor remains fixed relative to the ship even in adverse conditions, preventing collisions between the anchor and the ship, and thus ensuring the safety and reliability of the entire anchoring system.

[0023] 3. The present invention further stabilizes the anchor by clamping the anchor rod with an elastic clamp. As the anchor is retracted, the anchor rod approaches the cleat, and the elastic clamp guides the anchor rod into the cleat, ensuring effective clamping regardless of the position and angle of the anchor rod, thereby ensuring that the anchor rod is firmly fixed in the self-locking area.

[0024] At the same time, the elastic clamp and the cleat work together to form a self-locking area that limits both horizontal and vertical positioning, ensuring that the anchor rod does not move unnecessarily in any direction. This not only makes the locking and releasing process of the anchor more efficient and reliable, but also significantly improves the safety and stability of the ship in various sea conditions, effectively preventing the anchor from loosening or slipping due to external forces, and ensuring the safety of the ship.

[0025] 4. This invention utilizes a first linkage between the piston rod and the slide to synchronize the movement of the guide wheel, thereby precisely controlling the speed of anchor chain retraction and deployment. Simultaneously, a second linkage between the piston rod and the slide enables synchronized movement of the cleat, enabling the cleat to unlock and self-lock the anchor rod. This not only effectively regulates the anchor chain retraction and deployment speed, but also ensures that the anchor remains securely locked after retraction, improving the operational efficiency and safety of the entire anchoring system.

DETAILED DESCRIPTION

[0037] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] See also Figures 1-6 As shown, a ship anchoring device based on intelligent hydraulic drive includes a frame 1, on which a hydraulic drive mechanism for driving the anchor chain 21 to retract and release the anchor 2 is provided. The frame 1 is also provided with a stabilizing mechanism for keeping the anchor 2 stably retracted and released, and the stabilizing mechanism includes guide wheels 3 symmetrically arranged on both sides of the anchor chain 21 and a locking structure 4 that cooperates with the two guide wheels 3 to fix the anchor 2, each of the guide wheels 3 can move on the frame 1 toward the anchor chain 21, and each guide wheel 3 is provided with a rubber ring 31, when the two guide wheels 3 approach each other and squeeze the anchor chain 21, the lowering of the anchor 2 is in a deceleration state, and the locking structure 4 remains in an unlocked state, and when the two guide wheels 3 move away from each other and do not squeeze the anchor chain 21, the retraction of the anchor 2 is in a uniform speed state, and the locking structure 4 remains in a state to be self-locked.

[0039] The hydraulic drive mechanism is not shown in the figures.

[0040] When the ship needs to lower the anchor chain 21 to achieve mooring, the hydraulic drive mechanism on the frame 1 starts to work, driving the sprocket wrapped around the anchor chain 21 to rotate by controlling the pressure changes in the internal oil circuit, thereby releasing the anchor chain 21. When the anchor 2 needs to be lowered at a slower speed, the guide wheels 3 set on both sides of the anchor chain 21 move toward the anchor chain 21. The two guide wheels 3 approach each other, gradually squeezing the anchor chain 21 located in the middle. As the distance between the guide wheels 3 decreases, the pressure they exert on the anchor chain 21 increases, causing the speed of the anchor chain 21 to decrease, thereby achieving a smooth and decelerated lowering of the anchor 2.

[0041] At the same time, during the lowering process of the anchor 2, the locking structure 4 remains unlocked, allowing the anchor chain 21 to freely pass through the guide wheel 3 and the locking structure 4, ensuring a smooth lowering process. This ensures accurate lowering of the anchor 2 even in adverse sea conditions, reducing the risks associated with sudden impact or overly rapid lowering.

[0042] On the contrary, when it is necessary to recover the anchor 2, the hydraulic drive mechanism works in the reverse direction, driving the sprocket to reverse and pull back the anchor chain 21. At this time, the two guide wheels 3 move away from each other and no longer squeeze the anchor chain 21, so that the anchor chain 21 can be quickly and evenly pulled back to the ship with less resistance.

[0043] At the same time, the locking structure 4 is in a waiting state for self-locking, ready to fix the position of the anchor 2 immediately after the anchor chain 21 is fully retracted, to prevent the anchor 2 from colliding with the ship and to improve the stability of the anchor 2 after it is recovered.

[0044] See also Figure 1-Figure 4 and Figures 6-10 As shown, the locking structure 4 has clamping plates 41 symmetrically arranged on both sides of the anchor chain 21 and located below the guide wheel 3. Each of the clamping plates 41 can move on the frame 1 toward the anchor 2. When the anchor 2 is clamped between the two clamping plates 41, the anchor 2 is in a locked state, so that the anchor 2 remains stable relative to the ship.

[0045] When the anchor 2 needs to be locked, the clamping plates 41 located on both sides of the anchor chain 21 and below the guide wheel 3 move inward on the frame 1 and can accurately approach the middle anchor chain 21.

[0046] As the two cleats 41 gradually approach and finally clamp the anchor chain 21, the anchor 2 is firmly fixed between them and enters a locked state, ensuring that the anchor 2 remains stable relative to the ship and prevents it from moving unnecessarily due to external forces, thereby ensuring the safety and stability of the ship when moored.

[0047] See also Figures 1-6As shown, the locking structure 4 further comprises an anchor rod 22 provided on the anchor 2 and with both ends extending towards each clamping plate 41 , and each clamping plate 41 is provided with a slot in which the corresponding end of the anchor rod 22 can be clamped.

[0048] When the clamping plate 41 moves toward the anchor 2 and clamps the anchor chain 21, the two ends of the anchor rod 22 are just aligned and enter the corresponding slots. As the clamping plate 41 is finally closed, the ends of the anchor rod 22 are firmly stuck in the slots, thereby ensuring that the anchor 2 is stably locked.

[0049] This not only enhances the stability of the locking structure 4 but also effectively prevents the anchor 2 from accidentally loosening or sliding due to external forces, significantly improving the safety and reliability of the vessel during navigation. Even in adverse sea conditions, the anchor 2 remains fixed relative to the vessel, ensuring safety and stability.

[0050] See also Figure 2-Figure 4 and Figures 6-10 As shown, a rubber layer 411 is provided in the slot of each clamping plate 41 to buffer the squeezing force of the clamping plate 41 on the end of the anchor rod 22 and increase the friction force.

[0051] When the splint 41 moves toward the anchor 2 and inserts the end of the anchor rod 22 into the slot provided therein, the rubber layer 411 in the slot can provide a buffering effect while the splint 41 applies an extrusion force to the end of the anchor rod 22, thereby reducing direct impact force and protecting the anchor rod 22 and the splint 41 from damage.

[0052] Furthermore, the material properties of the rubber layer 411 significantly increase friction, ensuring that the anchor rod 22 is securely held within the slot and preventing loosening or slipping due to vibration or other external forces. This not only extends the service life of the clamping plate 41 but also significantly enhances the reliability of the locking structure 4, allowing the vessel to navigate safely and stably in all sea conditions and reducing the risk of the anchor 2 accidentally striking the vessel.

[0053] See also Figure 2-Figure 4 and Figures 6-10 As shown, a slider 42 is slidingly provided on the frame 1 for each splint 41 to be rotatably connected thereto, and the slider 42 is provided with an elastic member 421 that can press the splint 41 inwardly, and the inner side of the lower end of each splint 41 also has a slope. When the end of the anchor rod 22 passes through the splint 41 along the slope, the splint 41 is pushed to rotate outward, and at this time the elastic member 421 is in a compressed state.

[0054] During the raising process of the anchor 2, the two cleats 41 slide on the frame 1 to a predetermined position via the slider 42 and remain in the self-locking state. As the anchor 2 rises, the end of the anchor rod 22 first contacts the slope at the lower end of the cleats 41, causing the cleats 41 to rotate about their pivot points with the slider 42, while compressing the elastic member 421 on the slider 42.

[0055] As the end of the anchor rod 22 passes through the clamping plate 41 along the slope, the clamping plate 41 is guided by the slope and gradually rotates and opens, allowing the anchor rod 22 to pass smoothly. Once the anchor rod 22 completely crosses the slope and enters the slot on the clamping plate 41, the elastic member 421 returns to its original shape and pushes the clamping plate 41 closed, and the end of the anchor rod 22 is then clamped into the slot with the rubber layer 411.

[0056] The rubber layer 411 not only cushions the pressure exerted by the cleat 41 on the anchor rod 22 but also increases friction, ensuring a secure lock. Thus, once the anchor 2 is raised to the appropriate position, the cleat 41 automatically locks the anchor rod 22, stabilizing the anchor 2 relative to the vessel. This ensures that the anchor 2 smoothly transitions to a securely locked position during the ascent, preventing collision between the anchor 2 and the vessel.

[0057] See also Figure 2-Figure 4 and Figures 6-10 As shown, both ends of the anchor rod 22 are spherical structures, and the rubber layer 411 on each splint 41 has a recess into which the end of the anchor rod 22 can be embedded. When the splint 41 is pressed and reset, the end of the anchor rod 22 is sunk into the recess on the rubber layer 411 and is wrapped.

[0058] Both ends of the anchor rod 22 are spherical structures, which help to reduce friction between the anchor rod 22 and the clamping plates 41 and enable the anchor rod 22 to pass through the space between the clamping plates 41 more smoothly.

[0059] As the anchor 2 is raised, the end of the anchor rod 22 passes along the slope at the lower end of the cleat 41, and the cleat 41 is compressed and rotated open, allowing the anchor rod 22 to pass smoothly. Once the end of the anchor rod 22 passes the slope and reaches its position, the cleat 41 is reset under the action of the elastic member 421, and the end of the anchor rod 22 is properly embedded in the recess of the rubber layer 411, at which point the ball is completely enclosed by the rubber layer 411.

[0060] As the pressure from the cleat 41 is applied, the rubber layer 411 not only absorbs the pressure from the cleat 41 on the anchor rod 22, but also increases friction to ensure stability in the locked state. This prevents damage from hard contact, protects the anchor rod 22 and cleat 41 from wear, and extends their service life, thereby enhancing the stability of the anchor 2.

[0061] See also Figure 2-Figure 4 and Figure 7-Figure 9 As shown, a stopper 43 is provided on the frame 1 to prevent the slider 42 from continuing to move inward. When the two sliders 42 are in contact with the corresponding stopper 43, the two clamping plates 41 are in a state to be self-locked, forming a self-locking area.

[0062] The stopper 43 limits the range of motion of the slider 42, allowing the cleat 41 to precisely stop at the position suitable for capturing the end of the anchor rod 22, ensuring the accuracy of the subsequent locking action. In this state, the cleat 41 has been adjusted to the optimal position to await the entry of the anchor rod 22. Once the end of the anchor rod 22 arrives, the cleat 41, under the action of the elastic member 421, quickly closes and locks the anchor rod 22, effectively securing the anchor 2.

[0063] By presetting the position of the cleats 41, the locking mechanism 4 can be guaranteed to operate reliably even in rough seas, preventing the anchor 2 from failing to lock properly due to unexpected circumstances. Specifically, when the two sliders 42 respectively contact the corresponding stops 43, a preset locking readiness state is formed between the two cleats 41, ensuring that the cleats 41 can meet the arrival of the end of the anchor rod 22 at the optimal position and angle, and quickly complete the locking process, thereby ensuring that the anchor 2 remains stable relative to the ship and improving the safety and reliability of the entire anchoring device.

[0064] See also Figure 2-Figure 4 As shown, the frame 1 is provided with an elastic clamp 44 that can adaptively clamp the anchor rod 22. The elastic clamp 44 has a guide edge for guiding the anchor rod 22 into it. The elastic clamp 44 and the clamp plate 41 together form the self-locking area for horizontally and vertically limiting the anchor 2.

[0065] When the anchor rod 22 approaches the elastic clamp 44 as the anchor 2 is retrieved, the guide edge on the elastic clamp 44 guides the anchor rod 22 smoothly into the self-locking area. Since the elastic clamp 44 can adaptively clamp the anchor rod 22, it ensures that it can be effectively clamped regardless of the position and angle of the anchor rod 22.

[0066] At the same time, the elastic clamp 44 and the clamping plate 41 work together to form a self-locking area that provides both lateral and vertical positioning. Within this area, the anchor rod 22 is firmly fixed, preventing unnecessary movement of the anchor 2 in any direction. This makes locking and releasing the anchor 2 more efficient and reliable, ensuring the safety of the vessel.

[0067] See also Figure 2-Figure 4 and Figure 7-10 As shown, a hydraulic cylinder 5 is provided on the frame 1 for cooperating with the hydraulic drive mechanism to synchronously drive the two guide wheels 3 to move relative to each other, and a first linkage member 6 is provided between the working end of the hydraulic cylinder 5 and each guide wheel 3.

[0068] One hydraulic cylinder 5 is provided between each of the two slides 32 on the same side.

[0069] The hydraulic cylinder 5 is composed of a cylinder barrel 51 and a piston rod 52 inserted therein. The upper end of the piston rod 52 is provided with a piston sleeve 521. The cylinder barrel 51 is respectively provided with an upper interface 511 and a lower interface 512 that can be connected to a hydraulic drive mechanism for the flow of part of the hydraulic oil.

[0070] The frame 1 is provided with a sliding seat 32 for rotatingly connecting each guide wheel 3, and the frame 1 is provided with a sliding groove for the sliding seat 32 to slide. The first linkage member 6 is hingedly provided between each slide 32 and the lower end of the piston rod 52, and the first linkage member 6 is a plate structure.

[0071] When the piston rod 52 moves upward, the two slides 32, driven by the first linkage 6, move closer to each other. Conversely, when the piston rod 52 moves downward, the two slides 32, driven by the first linkage 6, move away from each other. This allows the two guide wheels 3 to control the speed of the anchor chain 21 during retraction and extension. Specifically, during lowering, the anchor chain 21 is squeezed, slowing the descent of the anchor 2. During retraction, the anchor chain 21 resumes its normal pulling speed, reducing resistance during the pulling process and maintaining a steady ascent speed for the anchor 2.

[0072] See also Figure 2-Figure 4 and Figure 7-10 As shown, a second linkage member 7 is provided between the working end of the hydraulic cylinder 5 and the slider 42. When the guide wheel 3 is driven to move closer to or away from the anchor chain 21, the slider 42 moves synchronously outward or inward under the drive of the second linkage member 7, so that the splint 41 moves away from or closer to the anchor 2.

[0073] A second linkage member 7 is hingedly provided between each slider 42 and the lower end of the corresponding piston rod 52 , and the second linkage member 7 is a plate structure.

[0074] A guide rod 422 for guiding the movement of the slider 42 is fixedly provided on the frame 1 , and a guide opening is provided on the slider 42 for slidingly sleeved on the guide rod 422 .

[0075] When the piston rod 52 moves upward, the slider 42 slides outward under the drive of the second linkage member 7. Conversely, when the piston rod 52 moves downward, the slider 42 slides inward under the drive of the second linkage member 7. This allows the two clamping plates 41 to unlock and self-lock with the anchor rod 22 on the anchor 2, ensuring that the anchor 2 remains stable after being retracted.

[0076] The present invention realizes speed control and stable locking of the anchor 2 during the lowering and recovery process by means of the guide wheels 3 and the clamping plates 41 arranged on both sides of the anchor chain 21.

[0077] The guide wheel 3 precisely moves to squeeze or release the anchor chain 21, allowing the anchor 2 to be lowered smoothly and decelerated, or quickly retracted, reducing the risk of sudden impact and improving safety. The clamping plate 41, driven by the slider 42 and elastic member 421, automatically locks the anchor rod 22, ensuring the anchor 2 remains in place and preventing accidental collisions.

[0078] Furthermore, the elastic clamp 44 guides the anchor rod 22 into the self-locking zone and, in conjunction with the clamping plate 41, forms a horizontal and vertical limit, ensuring that the anchor rod 22 remains firmly in place. This not only improves the operational efficiency and reliability of the anchoring device, but also significantly enhances the safety and stability of the vessel in various sea conditions, ensuring the safety of the vessel.

[0079] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, and such modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims.
