Description

Technical Field

[0001] This utility model belongs to the technical field of ship berthing equipment, and relates to a quick release hook, especially a water-soaked release hook mechanism for quick release of cover plates during non-flood season. Background Technology

[0002] Traditional rapid release cable hook devices face significant technical challenges when used in waterways with substantial water level fluctuations, such as the Yangtze River basin. Rising water levels during the flood season lead to prolonged immersion of the equipment, causing metal corrosion. Simultaneously, debris such as silt and rocks in the water can easily cause the release mechanism to jam and malfunction. Conventional land-based release cables only undergo ordinary rust prevention treatment, and their surface protective layer will peel off under prolonged immersion, leading to electrochemical corrosion of the internal steel structure. During flood season immersion, suspended matter in the open mechanical transmission structure can accumulate at hinge points and transmission gaps, obstructing the movement of critical components such as the lever mechanism and transmission mechanism.

[0003] To address these issues, existing technologies have developed rapid cable detachment hook devices for flood-prone areas using snap-fit ​​or bolted connections for the upper and lower cover plates. However, snap-fit ​​covers are prone to detachment under water pressure, allowing mud and other debris to enter the device. Bolted devices, on the other hand, present difficulties in disassembly after the flood season, as mud can easily enter the bolt holes or the bolts can rust, making disassembly inconvenient, time-consuming, and labor-intensive. These shortcomings severely impact the reliability and ease of use of the equipment. Utility Model Content

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] In existing technologies, land-based mooring hook equipment has long faced problems of metal corrosion and debris intrusion caused by flooding during the flood season. Conventional equipment using clips or bolts to fix the cover plate has significant drawbacks: clips are prone to detachment under water flow impact, leading to protective failure, and bolted connections are difficult to disassemble due to siltation and corrosion. When mooring hooks are used at Yangtze River docks during the non-flood season, inconvenient cover plate disassembly often delays operations, while frequent replacement of corroded parts is necessary during flood season maintenance.

[0041] To address the aforementioned issues, researchers observed the advantages of elastic elements in dynamic connections, discovering that the spring structure can provide continuous tension to keep the cover closed while also enabling rapid separation through deformation. Based on this, a bidirectional elastic connection was proposed to replace rigid fixing, ensuring both flood season protection stability and rapid disassembly during non-flood seasons. By setting corresponding upper and lower hook-and-loop structures linked to the spring, a reversible elastic locking mechanism is formed.

[0042] Therefore, in some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, based on the above design concept, this application proposes a release hook 100, a first cover plate 200 and a second cover plate 300 covering the top and bottom openings of the release hook 100 respectively, and two sets of locking springs 400 connecting the front and rear ends of the first cover plate and the second cover plate 200; the front and rear ends of the first cover plate 200 are respectively provided with a first pull hook 210 and a second pull hook 220, and the front and rear ends of the second cover plate 300 are respectively provided with a first pull ring 310 and a second pull ring 320 corresponding to the first pull hook 210 and the second pull hook 220; the two sets of locking springs 400 are respectively provided in the first mounting area 111 and the second mounting area 112 inside the release hook 100, and their lower ends are respectively connected to the corresponding first pull ring 310 and the second pull ring 320, and their upper ends are respectively detachably connected to the corresponding first pull hook 210 and the second pull hook 220, and their top ends are each provided with a lifting lug 403 exposed on the top of the first cover plate 100.

[0043] The locking spring 400 is a helical spring with elastic restoring force, specifically made of stainless steel spring wire, which provides the connecting force between the cover plates through elastic deformation. The lifting lug 403 is a T-shaped or ring-shaped traction component set at the top of the spring, which can be fixed to the end of the spring by welding, making it easy for operating tools to hook and pull. The first installation area 111 and the second installation area 112 refer to the spring accommodating space formed between the original components on both sides of the cantilever 121 inside the release hook, used to fully utilize the existing empty space inside the release hook 100 to install the locking spring 400.

[0044] Specifically, during installation in the flood season, operators fix the second cover plate 300 to the bottom of the release hook and connect the lower end of the locking spring 400 to the pull ring of the second cover plate 300. Then, the first cover plate 200 is installed. By pulling the lifting lug 403, the spring is stretched so that its upper end hooks onto the pull hook of the first cover plate 200, forming an elastic connection between the upper and lower cover plates. The preload of the spring ensures that the cover plate fits tightly against the opening of the release hook, effectively resisting the impact of water flow. During disassembly outside the flood season, simply pulling the lifting lug 403 releases the connection between the spring and the first cover plate 200, allowing for quick removal of the first cover plate. Throughout this process, the locking spring 400 remains fixedly connected to the second cover plate 300, preventing parts from scattering or being lost.

[0045] Compared to existing technologies, traditional snap-fit ​​connections rely on mechanical clamping force, which is prone to fatigue failure under long-term water flow. Bolt fixing requires specialized tools and poses a risk of thread corrosion. This solution uses the elastic deformation of a locking spring 400 to switch the connection state, eliminating the need for threaded fasteners and avoiding the reliance on disassembly tools and the problems of rust and jamming. The design employing two sets of hooks and rings at the front and rear ensures even force distribution at the connection point, resulting in higher structural stability compared to single-point snap-fit ​​connections.

[0046] Through the above technical solution, this application achieves the dual functions of reliable closure of the cover plate during the flood season and rapid disassembly during the non-flood season. The elastic connection of the locking spring 400 can both resist the impact of water flow to maintain the position of the cover plate and achieve rapid separation through a simple pulling action. The closed space formed by the upper and lower cover plates effectively prevents the intrusion of mud and sand, and the cooperative design of the hook and spring makes the disassembly operation without special tools, significantly improving the maintenance efficiency and operation convenience of the cable release hook equipment.

[0047] In some of these embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, this application further proposes that the release hook 100 is a known existing product, which mainly includes a hook plate frame 110, an anchor hook 120, a lever mechanism 130, a transmission mechanism 140, and a release block 150. The anchor hook 120 and the release block 150 are respectively hinged to the front and rear ends of the hook plate frame 100. The lever mechanism 130 and the transmission mechanism 140 are located inside the hook plate frame 100, and the lever mechanism 130 is linked with the release block 150 through the transmission mechanism 140 to drive the release block 150 to flip and disengage from the anchor hook 120.

[0048] Specifically, the cable hook plate frame 110, as a closed load-bearing structure, has hinged fulcrums at its front and rear ends for the anchor hook 120 and the release block 150, respectively. The lever mechanism 130 and the transmission mechanism 140 are completely integrated within the cable hook plate frame 100, forming a closed mechanical linkage system. When the lever 130 is operated, the driving force is converted through the transmission mechanism 140 into a flipping action of the release block 150, causing it to disengage from the anchor hook 120. During this process, the anchor hook 120 rotates and releases the cable due to the loss of its limiting constraint. The closed structure isolates the transmission component 140 from the external environment, preventing sediment carried by floodwaters during the flood season from intruding into the internal moving parts, while also reducing the corrosion of metal components by corrosive media.

[0049] In some embodiments, this application further proposes that the body structure of the release hook 100 is coated with a zinc layer on its surface by hot-dip galvanizing, and a waterproof paint layer is coated on the zinc layer surface. Hot-dip galvanizing refers to immersing the entire release hook 100 in molten zinc, forming a continuous and dense zinc-iron alloy layer on its surface. The zinc layer preferentially reacts with the corrosive medium through sacrificial anode action, thereby protecting the base metal. The waterproof paint layer refers to a coating made of epoxy resin or polyurethane-based materials, specifically applied in two coats using spraying or brushing processes, with a single layer thickness controlled at 80-120 micrometers. This paint layer fills the micropores on the zinc layer surface and forms a physical barrier, preventing the penetration of moisture and corrosive ions.

[0050] Specifically, after degreasing and pickling pretreatment, the hook substrate is immersed in molten zinc, forming a uniform zinc plating layer on its surface. The zinc layer and the base metal form an electrochemical protection system through metallurgical bonding. In a water-immersion environment, zinc acts as the anolyte, preferentially corroding and slowing down the corrosion process of the base steel. Subsequently, a waterproof paint layer is applied to the zinc layer surface. After curing, it forms a dense and strongly adhesive continuous film that covers microscopic pores and defects on the zinc plating surface, further preventing corrosive media such as moisture, dissolved oxygen, and chloride ions from contacting the metal substrate. The zinc layer and paint layer form a complementary protection mechanism: the zinc layer provides active electrochemical protection, while the paint layer provides passive physical isolation. Their synergistic effect can cope with the long-term corrosive environment under periodic water immersion conditions.

[0051] Through the above technical solution, this application effectively solves the problem of protective layer peeling caused by metal corrosion in the release hook under periodic immersion conditions. The zinc layer slows down the corrosion process of the substrate through sacrificial anode action, while the waterproof paint layer blocks the penetration of corrosive media through physical isolation. The synergistic protection of the two allows the release hook to maintain structural integrity and functional reliability when used during non-flood seasons, reducing the frequency of maintenance and equipment replacement costs caused by corrosion.

[0052] In some of these embodiments, such as Figure 6 and Figure 7As shown, this application further proposes that both the first cover plate 200 and the second cover plate 300 have a U-shaped plate structure and are made of stainless steel or aluminum alloy. The U-shaped plate structure refers to a plate-shaped component with a U-shaped cross-section, whose two edges extend upwards or downwards to form an enclosure structure. This can be achieved using stamping or bending processes. This structure can cover the top and bottom openings of the release hook, forming a three-sided closed cover. The stainless steel material is made of 304 stainless steel or 316L stainless steel, which forms a chromium oxide passivation film in humid environments to resist corrosion.

[0053] The aluminum alloy material is made of 5052 aluminum alloy or 6061 aluminum alloy. This material is anodized to form an aluminum oxide layer on the surface to improve weather resistance.

[0054] In some of these embodiments, such as Figure 1 , Figure 5 , Figure 6 , Figure 9 , Figure 10 and Figure 11 As shown, this application further proposes that the first hook 210 and the second hook 220 are arranged diagonally, and the first pull ring 310 and the second pull ring 320 are also arranged diagonally. The diagonal arrangement means that the first hook 210 and the second hook 220 are located at opposite ends of the first cover plate 200. The corresponding diagonal arrangement means that the positions of the first pull ring 310 and the second pull ring 320 correspond to the diagonal positions of the hooks. This arrangement ensures that the locking springs 400 form a symmetrical elastic preload when connected, enhancing the overall stability of the cover plate, and creating a spatially symmetrical tension distribution between the two sets of locking springs, avoiding uneven force distribution on one side.

[0055] Specifically, in the installed state, the first hook 210 and the first pull ring 310 are connected by one of the locking springs 400, and the second hook 220 and the second pull ring 320 are connected by another locking spring 400. The diagonal distribution of the two sets of springs ensures that each edge of the upper and lower cover plates bears uniform tension. When subjected to water flow impact, the symmetrical tension can offset local stress concentration and prevent the cover plate from tilting up on one side. During disassembly, the operator only needs to simultaneously disconnect the two sets of diagonally arranged locking springs 400 to quickly remove the first cover plate 200.

[0056] Through the above technical solution, this application solves the risk of detachment during the flood season caused by insufficient connection stability between the first cover plate 200 and the second cover plate 300 by using a diagonal connection with the locking spring 400. Simultaneously, the diagonal tension distribution reduces disassembly steps, meeting the need for rapid cover plate separation during non-flood seasons. This design effectively prevents cover plate failure and ensures the long-term reliability of the cable release hook 100 under periodic immersion conditions.

[0057] In one specific implementation, such as Figure 9 and Figure 10 As shown, this application further proposes that the first hook 210 is composed of a first through-hook hole 211, a first hook hole 212, a first hook rod 213 located between the first through-hook hole 211 and the first hook hole 212, and a first reinforcing plate 214 welded to the bottom of the first hook rod 213, for threading through and hooking the upper hook 401 of the corresponding locking spring 400.

[0058] The first through-hole 211 refers to the channel provided at the front end of the first cover plate 200 for guiding the upper hook 401 of the locking spring 400 through. It can be implemented using a directional, circular, or elliptical through hole, with a diameter slightly larger than the diameter range of the lifting lug 403 and the upper hook 401 for easy insertion. The first hook hole 212 refers to the hole provided at the front end of the first cover plate 200 for accommodating and locking the upper hook 401. It is spaced apart from the first through-hole by the first hook rod 213 to limit the displacement of the upper hook 401. The first hook rod 213 refers to the elongated plate connecting the first through-hole 211 and the first hook hole 212, used to support the upper hook 401. The first reinforcing plate 214 refers to the reinforcing member welded to the bottom of the first hook rod 213, with the welding position located at the bottom of the first hook rod 213 to enhance bending strength.

[0059] Specifically, during installation, the upper hook 401 of the locking spring 400 first passes through the first hook hole 211. Then, the operator pulls the spring by lifting the lug 403, causing its outer end to cross the first hook rod 213 and move to the position of the first hook hole 212. At this point, the upper hook 401 is embedded in the first hook hole 212 and is laterally limited by the first hook rod 213. The first reinforcing plate 214 increases the cross-sectional area at the base of the first hook rod 213 to prevent plastic deformation or breakage of the hook rod under the spring tension. During disassembly, the lifting lug 403 is pulled upwards, causing the upper hook 401 to disengage from the first hook hole 212 and the first hook rod 213. After the spring retracts, it automatically retracts into the first hook hole 211, achieving rapid separation of the first cover plate 200 from the locking spring 400.

[0060] Similarly, such as Figure 9 and Figure 10 As shown, this application further proposes a second hook 220 consisting of a second hook hole 221, a second hook hole 222, a second hook rod 223 located between the second hook hole 221 and the second hook hole 222, and a second reinforcing plate 224 welded to the bottom of the second hook rod 223, used for threading and hooking the upper hook 403 of the corresponding locking spring 400. Its structural features and working principle are the same as the first hook 210, and will not be described again here.

[0061] In some of these embodiments, such as Figure 10As shown, this application further proposes that the bottom of the front and rear ends of the first cover plate 200 and the top of the cable hook plate frame 110 of the cable release hook 100 are respectively provided with a number of first anti-slip pads 230 arranged at intervals, and the front and rear edges are provided with first guard edges 240 arranged vertically downward.

[0062] The first anti-slip pad 230 refers to a friction-enhancing component located at the bottom of the first cover plate 200 in contact with the cable hook plate frame 110. It can be made of rubber or silicone and is arranged at intervals to form multiple contact points, thereby increasing the frictional resistance between the first cover plate 200 and the cable hook plate frame 100. The first retaining edge 240 refers to a continuous barrier structure extending vertically downwards along the front and rear edges of the cover plate. It can be implemented using a metal folded edge integrally formed with the cover plate or welded additional metal strips, and is used to form a lateral sealing barrier.

[0063] Specifically, the first anti-slip pads 230 are spaced apart on the support surface of the bottom of the first cover plate 200 where it contacts the cable hook plate frame 110. These pads generate localized pressure through multiple contact points, suppressing lateral sliding of the cover plate under the impact of floodwaters through friction. The first retaining edge 240 extends downwards from the edge of the first cover plate 200 and wraps around the side of the cable hook plate frame 110, preventing silt carried by lateral water flow from entering the equipment through the gap between the cover plate and the cable hook plate frame 110. The spaced anti-slip pads and the continuous retaining edge complement each other; the former counteracts lateral displacement through dynamic friction, while the latter prevents foreign objects from entering through static sealing. Together, they ensure the positional stability of the first cover plate 200 under the impact of water flow.

[0064] In some of these embodiments, such as Figure 6 and Figure 10 As shown, this application further proposes that the top of the front and rear ends of the second cover plate 300 and the bottom of the cable hook plate frame 110 on the cable hook 100 are respectively provided with a number of second anti-slip pads 330 arranged at intervals, and the front and rear edges are provided with second guard edges 340 arranged vertically upward.

[0065] The second anti-slip pad 330 refers to an elastic friction element located on the contact surface between the top of the second cover plate 300 and the bottom of the cable hook plate frame 100. It can be made of rubber or silicone and arranged at intervals to form a multi-point contact structure. This structure increases local pressure to enhance frictional resistance during installation in the flood season. The second retaining edge 340 refers to a limiting flange extending vertically upwards along the front and rear edges of the second cover plate 300. It can be a bent structure integrally formed with the second cover plate 300. This structure forms a physical barrier to prevent lateral displacement during the flood season.

[0066] Specifically, during the installation phase in the flood season, the spaced arrangement of the second anti-slip pads 330 creates an independent pressure zone between each anti-slip pad unit and the bottom of the cable hook plate frame 110, generating a high frictional torque through concentrated load to resist the impact of water flow; the vertically arranged second baffle 340 is embedded in the bottom edge of the cable hook plate frame 110, forming a three-dimensional limiting constraint to prevent the second cover plate 300 from moving horizontally.

[0067] In some of these embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12 As shown, this application further proposes that the upper end of the locking spring 400 is configured as an upper hook 401 detachably connected to the first hook 210 and the second hook 220, and the lower end is configured as a lower hook 402 connected to the first pull ring 310 and the second pull ring 320. The top of the upper hook 401 is fixedly provided with a lifting lug 403 for manually pulling the upper hook 401 to hook it onto the first cover plate 200.

[0068] The upper hook 401 refers to a hook-shaped structure at the top of the spring that forms a detachable connection with the cover plate hook. Specifically, it can be implemented using a metal rod bent into a ring shape, with the hook portion matching the hook hole size for locking when engaged in the hook hole under tension. The lower hook 402 refers to a hook-shaped structure at the bottom of the spring that is fixedly connected to the second cover plate 300 via a pull ring. Specifically, it can be implemented using a bent metal part symmetrical to the upper hook 401, with the hook portion directly inserted into the pull ring to form a fixed connection. The lifting lug 403 refers to a T-shaped or ring-shaped operating component fixed to the top of the upper hook 401. Specifically, it can be connected to the top of the spring by welding or riveting, providing a point of force for manual pulling. Its exposed design at the top of the first cover plate 200 facilitates tool clamping.

[0069] Specifically, during the flood season, when installing the cover plate, the lower hook 402 is pre-fixed to the pull ring on the second cover plate 300. The operator pulls the upper hook 401 by lifting the lifting lug 403, causing it to engage with the hook hole on the first cover plate 200 under spring tension, thus achieving an elastic connection between the upper and lower cover plates using spring force. During disassembly outside the flood season, the lifting lug 403 is pulled in the opposite direction to disengage the upper hook 401 from the corresponding hook hole, and the first cover plate 200 can be quickly removed after the spring contracts. In this process, the elastic deformation of the spring provides the pre-tightening force required for locking the cover plate and allows the switching of the connection state to be completed through a single operating point, without the need for additional tools or complex steps.

[0070] Through the above technical solutions, this application achieves the functional requirements of stable closure of the first cover plate 200 during the flood season and rapid detachment during the non-flood season, resolving the technical contradictions of easy detachment of traditional buckles and easy corrosion of bolts. The elastic connection structure simplifies the operation process, reduces maintenance costs, and improves the reliability of the cable release hook equipment under periodic immersion conditions while ensuring sealing.

[0071] In summary, combining Figures 1 to 12 As shown, the cable release hook 100 is pre-treated with hot-dip galvanizing to form a galvanized layer on its outer surface and then coated with waterproof paint to increase the equipment's corrosion resistance. The working principle of this water-soaked cable release hook and non-flood season cover plate quick-release mechanism is as follows:

[0072] During the flood season, first install the second cover plate 300 at the bottom of the cable hook plate frame 110, and set the two sets of locking springs 400 in the first installation area 111 and the second installation area 112 inside the cable hook 100 respectively. Then fix the pull hooks 402 at the lower end of the two sets of locking springs 400 to the first pull ring 310 and the second pull ring 320 of the second cover plate 300 respectively.

[0073] Then, the first cover plate 200 is installed on the top of the cable hook plate frame 110, and the lifting lugs 403 at the top of the two sets of locking springs 400 are aligned with the hook holes of the first hook 210 and the second hook 220, and are located in the hook holes; then, the operator manually clamps the lifting lugs 403 with hooks or pliers and pulls them upward, which simultaneously drives the locking springs 400 to stretch and generate elastic deformation, exposing the upper hook 401 and hooking it onto the corresponding hook rod. One end of the upper hook 401 is embedded in the corresponding hook hole, thereby connecting the first cover plate 200 and the second cover plate 300 through the locking springs 400, which can effectively avoid the problem of the cover plate detaching.

[0074] During non-flood seasons, when the cable release hook needs to be activated, the operator manually clamps and pulls the lifting lug 403 upwards using a hook or pliers to detach the lifting lug 403 from the hook rod. Under the elastic action of the locking spring 400 itself, it retracts into the hook hole, completing the separation of the locking spring 400 from the first cover plate 200. This allows for easy disassembly of the first cover plate 200, enabling the rapid activation of the cable release hook 100. Installation and disassembly are simple, and the operation is convenient and quick.

[0075] 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.
