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 quick release hook device for flooding during the flood season. Background Technology

[0002] Traditional rapid release hook equipment is mainly divided into two types: marine and land-based. Land-based release hooks are installed on the quay foundation. In waters with significant water level fluctuations, such as the Yangtze River basin, existing equipment faces two prominent technical challenges: first, metal corrosion caused by prolonged immersion during the flood season; and second, the potential for mud, sand, rocks, and other debris in the water to cause jamming and failure of the release mechanism. Conventional land-based release hooks only use ordinary rust prevention treatment, and their surface protective layer will peel off under long-term immersion, leading to electrochemical corrosion of the internal steel structure. Simultaneously, during flood season immersion, suspended matter in the open mechanical transmission structure will accumulate at the hinge points and transmission gaps, obstructing the movement of key components such as the lever mechanism and transmission mechanism.

[0003] These problems make existing equipment unsuitable for the special conditions of periodic flooding, often resulting in malfunctions in the release mechanism or damage to the structure after the flood season, seriously affecting the mooring safety of ships. Currently, there is a lack of release mechanism specifically designed for periodic flooding conditions on the market, therefore, there is an urgent need to develop a new structure with dual protection features.

[0048] 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.

[0049] 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.

[0050] In existing technologies, land-based release cable hook devices are typically installed on the shoreline of wharves, and their design does not consider long-term submersion conditions. During the flood season in the Yangtze River basin, when water levels rise, traditional equipment is completely submerged in the river, leading to rapid corrosion and failure of metal components. Simultaneously, silt and rocks carried by the water flow can easily penetrate the equipment, causing the release mechanism to jam and malfunction. Existing technologies lack protective structures for submerged environments, and after the flood season, the equipment often loses its release cable function due to corrosion or mechanical failure.

[0051] To address these issues, researchers discovered that traditional cable release hooks face a dual risk of failure under immersion conditions: metal corrosion leading to reduced structural strength, and foreign object intrusion causing the mechanism to jam. To address corrosion resistance, a composite protection system combining hot-dip galvanizing and a waterproof coating was considered. To prevent jamming, removable protective covers were added to the top and bottom of the equipment, forming a closed structure to block foreign objects. By isolating the internal transmission mechanism from the external environment while maintaining access for post-flood maintenance, a balance between protection and functionality is achieved.

[0052] Therefore, in some embodiments, such as Figures 1 to 8 As shown, based on the above design concept, this application proposes a rapid cable hook release device for flooding during the flood season, including a cable hook frame 100, an anchor hook 200, a release block 500, a lever mechanism 300, a transmission mechanism 400, and detachable first cover plate 600 and second cover plate 700. The cantilever portion 202 at the inner end of the anchor hook 200 is embedded in the slot 502 at the bottom of the release block 500. The lever mechanism 300 drives the release block 500 to flip and release through the transmission mechanism 400. The first cover plate 600 and the second cover plate 700 are respectively installed on the top and bottom of the cable hook frame 100, forming a closed space to protect the internal mechanism.

[0053] The cable hook plate frame 100 refers to the main frame supporting the unhooking mechanism. It can be constructed from welded steel plates to form a symmetrical upright plate 101 structure, with components connected via front and rear hinge shafts. The anchor hook 200 is a metal component with a bent hook portion 201 and a cantilever portion 202, with the cantilever portion 202 mechanically interlocked with the unhooking stop block 500. The unhooking stop block 500 is a flipping component with a slot 502, linked to the transmission mechanism 400 via a latch tongue 501. The lever mechanism 300 is an L-shaped operating lever, mounted on the side wall of the plate frame via a fixed shaft, used to trigger the transmission action. The transmission mechanism 400 transmits the lever action to the unhooking stop block 500. The first cover plate 600 and the second cover plate 700 are protective components covering the upper and lower openings of the cable hook plate frame 100, made of stainless steel and fixed with bolts.

[0054] Specifically, before the flood season, the first cover plate 600 and the second cover plate 700 are bolted to the top and bottom openings of the hook plate frame 100, respectively, completely enclosing the cantilever 202, lever mechanism 300, transmission mechanism 400, and unhooking block 500 inside the frame. The first cover plate 600 and the second cover plate 700 prevent water-borne sediment from entering the equipment and avoid foreign objects from jamming the transmission components. The hook plate frame 100 and its internal metal components are hot-dip galvanized and coated with a waterproof paint layer, forming a double anti-corrosion barrier. After the flood season, removing the first cover plate 600 exposes the internal mechanism. When the lever mechanism 300 is turned, its lower end pushes the first lever arm 403 of the transmission mechanism 400, causing the fork shaft sleeve 402 to rotate around the fork shaft 401, which in turn moves the roller 406 at the top of the second lever arm 405, thereby releasing the latch 501 of the unhooking block 500. The release block 500 flips under the pull of the cable, releasing the lock on the cantilever part 202 of the anchor hook 200, thereby enabling the cable to quickly detach.

[0055] Compared to existing technologies, traditional land-based cable release hooks lack a closed protective structure, allowing mud and sand to directly intrude into the gaps between transmission components during flood season, causing the mechanism to jam. This solution uses detachable first cover plate 600 and second cover plate 700 to form a physical isolation barrier, clearly distinguishing the flood season protection phase from the operational phase. Traditional equipment uses ordinary anti-rust paint, which is prone to peeling and failure under long-term immersion conditions. This solution employs a composite protective system of hot-dip galvanizing and a waterproof coating, significantly improving the corrosion resistance of the metal substrate.

[0056] The above technical solution completely isolates the internal structure of the equipment from the external environment during flood season, effectively preventing sediment deposition and foreign object jamming. Metal components undergo double anti-corrosion treatment, maintaining structural integrity even under long-term immersion conditions. After the flood season, removing the first cover plate 600 at the top of the protective structure allows normal operation of the lever mechanism 300, restoring the release function; operation and maintenance do not require complex disassembly. This solution, while maintaining the original release function, specifically addresses the challenges of corrosion prevention and anti-jamming in immersion environments.

[0057] In some of these embodiments, such as Figures 4 to 8 As shown, this application further proposes a rapid cable hook release device for flooding during the flood season, including a cable hook frame 100, which is composed of a vertical plate 101, a first hinge shaft 103, and a second hinge shaft 104. There are two vertical plates 101, which are arranged symmetrically on the left and right and spaced apart. Their front ends are fixedly connected by the first hinge shaft 103, and the inner side walls of their rear ends are provided with oppositely arranged second hinge shafts 104. Threaded holes 102 are opened at the front and rear ends of the top, respectively. The first hinge shaft 103 is hinged to the middle of the anchor hook 200, and the two second hinge shafts 104 on the left and right are respectively hinged to the two ends of the release block 500.

[0058] Specifically, the symmetrically arranged vertical plates 101 form a rigid frame, which evenly distributes the impact force of water flow during flood season, preventing deformation and jamming caused by unilateral force. The first hinge 103 shaft passes through the front ends of the two vertical plates 101 to form an integral connection, providing a stable rotation fulcrum for the anchor hook 200. The second hinge shafts 104 on the inner rear ends of the two vertical plates 101 are arranged in pairs, so that the two ends of the unhooking block 500 are synchronously supported and maintain balance during the flipping process. The threaded holes 103 at the top of the vertical plates 101 are connected to the first cover plate 600 and the second cover plate 700 by bolts, forming a closed structure to prevent foreign objects from entering the internal mechanism.

[0059] In addition, such as Figures 4 to 8 As shown, this application further proposes that the cable hook plate frame 100 also includes a first connecting block 105, a second connecting block 106, and a third connecting block 107. The two ends of the first connecting block 105 are fixed to the bottom of the front end of the two upright plates 101 near the first hinge shaft 103, and its top end is abutted and connected to the front end of the cantilever portion 202. The two ends of the second connecting block 106 are fixed to the bottom of the rear end of the upright plate 100, and it is inclined and set at the lower right corner of the second hinge shaft 104. The two ends of the third connecting block 107 are fixed to the top of the rear end of the upright plate 101, and it is inclined and set at the upper right corner of the second hinge shaft 104, and its front end is abutted and connected to the first cover plate 600.

[0060] The first connecting block 105 is a support structure connecting the bottom front ends of the two upright plates 101. It can be implemented as a welded or bolted metal block, used to connect the left and right upright plates 101 and limit the displacement of the cantilever 202, while also acting as a baffle to prevent foreign objects from entering. The second connecting block 106 is inclined at the lower right corner of the second hinge shaft 105. This inclined arrangement reduces the accumulation of sand and gravel in the area of ​​the second connecting block 106, and also acts as a baffle to prevent foreign objects from entering. The third connecting block 107 is a connecting structure connecting the top rear ends of the two upright plates 101. It provides an installation fulcrum for the first cover plate and also acts as a baffle to prevent foreign objects from entering.

[0061] In some of these embodiments, such as Figure 5 , Figure 7 and Figure 8 As shown, this application further proposes that the anchor hook 200 is hinged to the first hinge shaft 103 through the shaft hole in its middle, with the front end configured as a hook part 201 and the rear end configured as a cantilever part 202 that cooperates with the unhooking block 500.

[0062] The shaft-hole hinged installation refers to the through-hole structure in the middle of the anchor hook 200, which forms a rotating pair with the first hinge shaft 103. The bent hook portion 201 refers to the arc-shaped curved structure at the front end of the anchor hook 200, used to hook the cable and reduce the risk of cable slippage through the curved design. The cantilever portion 202 refers to the rigid support section extending from the rear end of the anchor hook 200, whose end shape is geometrically complementary to the groove 501 of the release block 500, achieving complete contact surface fit in the locked state.

[0063] In some of these embodiments, such as Figure 5 and Figure 6 As shown, this application further proposes a lever mechanism 300 including a lever body 301 and a fixed shaft 302, wherein: the lever body 301 has an L-shaped structure, the middle part is installed on the inner side wall of the cable hook plate frame 100 through the fixed shaft 302, and the lower end is abutted and connected to the first lever arm 403 at one end of the transmission mechanism 400.

[0064] The lever body 301 refers to a rigid rod with an L-shaped profile, which can be made of forged stainless steel. Its bending angle is controlled within the range of 90 to 120 degrees, forming a spatial separation between the lever fulcrum and the operating end. The fixed shaft 302 refers to a cylindrical support component that passes through the inner wall of the cable hook plate frame 100. Its diameter forms a clearance fit with the shaft hole in the middle of the lever body 301, allowing the lever body 301 to rotate around the fixed shaft 302.

[0065] Specifically, when an external force is applied to the operating end of the lever body 301, the L-shaped structure rotates around the fixed axis 302, generating a lever effect. The lower end abutting part pushes the first lever arm 403 of the transmission mechanism 400 to produce displacement. Since the short arm end of the L-shaped structure contacts the transmission mechanism 400, and the long arm end acts as an operating handle, a torque amplification effect is formed. By placing the lever mechanism 300 below the first cover plate 600, it is completely within the protection range of the cover plate, preventing foreign objects from entering the contact surface and affecting the normal use of the lever mechanism 300.

[0066] In some of these embodiments, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this application further proposes a transmission mechanism 40 including a fork shaft 401, a fork shaft sleeve 402, a first lever arm 403, and a second lever arm 405. The two ends of the fork shaft 401 are fixedly installed on the two inner side walls of the lower middle part of the cable hook plate frame 100, and the fork shaft sleeve 402 is rotatably sleeved on it. The first lever arm 403 is vertically arranged on the outer peripheral wall of one end of the fork shaft sleeve 402, and the second lever arm 405 is vertically arranged on the outer peripheral wall of the other end. A horizontally arranged limiting post 404 is vertically arranged at the outer end of the first lever arm 403, and the limiting post 404 can abut against the lower end of the lever body 301. The second lever arm 405 is composed of two sets of triangular plates arranged at intervals, and a roller 406 is installed at its top end through a pin. The bottom of the roller 406 abuts against the latch 503 on the unhooking block 500.

[0067] Specifically, when the lever mechanism 300 is operated, its lower end pushes the limiting post 404 of the first lever arm 403, causing the fork shaft sleeve 402 to rotate around the fork shaft 401. The roller 406 of the second lever arm 405 is displaced accordingly, pushing the latch 503 of the release block 500 through rolling contact. The two sets of triangular plate structures of the second lever arms 405 form a stable force transmission path when subjected to force. The rotatable fit between the fork shaft sleeve 402 and the fork shaft 401 ensures that the transmission mechanism maintains its operational flexibility even after being submerged during the flood season. The triangular plate structure of the second lever arms 405 enhances their resistance to deformation, ensuring the reliable disengagement of the release block 500 from the anchor hook 200.

[0068] In some of these embodiments, such as Figure 6 , Figure 7 and Figure 8As shown, this application further proposes a release block 500 including a block body 501, a latch 503, and a handle 504. The left and right ends of the block 501 are hinged to the second hinge shaft 104 on the inner side wall of the rear end of the cable hook plate frame 100, and a slot 502 that cooperates with the cantilever part 202 is provided at its bottom. One end of the latch 503 is vertically set on the outer peripheral wall of one end of the block body 501, and the other end is abutted and connected to the second lever arm 405 at the end of the transmission mechanism 400. The handle 504 is fixedly provided on the top.

[0069] Specifically, when the transmission mechanism 400 drives the second lever arm 405 to move, the roller 406 at its top disengages from the bolt tongue 503. The bolt tongue 503 and the stop block body 501 rotate around the second hinge axis 104 under the pull of the cable, causing the slot 502 to disengage from the cantilever portion 202. At this time, the stop block body 501 loses its constraint on the cantilever portion 202, and the anchor hook 500 completes the unhooking action under the tension of the cable. In the event of mud, sand, or foreign objects causing obstruction, external force can be directly applied by manually operating the handle 504 to forcefully drive the bolt tongue 503 and the stop block body 501 to rotate, preventing the mechanism from failing to operate due to external resistance.

[0070] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this application further proposes that the first cover plate 600 is a U-shaped plate structure made of stainless steel or aluminum alloy, which can be detachably installed on the top of the cable hook plate frame 100 or in the corresponding threaded holes 102 through a snap fastener or the first mounting holes 601 and the first bolts 602 at the four corners of the cover plate 600, so as to cover the top opening of the cable hook plate frame 100. Similarly, the second cover plate 700 is a U-shaped plate structure made of stainless steel or aluminum alloy, which can be detachably installed on the bottom of the cable hook plate frame 100 or in the corresponding threaded holes 102 through a snap fastener or the second mounting holes 701 and the second bolts 702 at the four corners of the cover plate 700, so as to cover the bottom opening of the cable hook plate frame 100.

[0071] The stainless steel or aluminum alloy material refers to the protective components consisting of the first cover plate 600 and the second cover plate 700, made of metal materials. Specifically, 316 stainless steel or 6061 aluminum alloy can be used, providing high corrosion resistance to withstand long-term immersion in river water. The U-shaped plate structure refers to a plate-shaped component with a three-sided enclosure, which can be manufactured using a stamping process. Its cross-sectional shape matches the top contour of the cable hook plate frame to achieve full coverage. The snap-fit ​​or bolt-on detachable installation refers to the connection and fixing method. Specifically, interference-fit snap-fits can be used to install the cable hook plate frame 100 at the top and bottom, such as... Figure 1 and Figure 2 Alternatively, a hexagonal bolt can be used to achieve this, such as... Figure 3 and Figure 4As shown, this design ensures both the stability of the protection during the flood season and facilitates subsequent disassembly and maintenance. Covering the top of the cable hook plate frame means using the first cover plate 600 and the second cover plate to seal and protect the openings at the top and bottom of the equipment, forming a physical barrier to prevent the intrusion of external foreign objects.

[0072] Through the above technical solutions, the first cover plate 600 and the second cover plate 700 of this application can effectively prevent foreign objects such as mud, sand and stones from entering the cable hook plate frame during flood season immersion, and avoid jamming failure between the lever mechanism 300 and the transmission mechanism 400; the cover plate made of stainless steel or aluminum alloy maintains structural integrity in long-term immersion environment, and prevents secondary pollution caused by corrosion failure of the protective cover plate; the detachable installation method ensures that the equipment can be quickly restored to normal use after the flood season.

[0073] In some of these embodiments, this application further proposes that the cable hook body, consisting of a cable hook plate frame 100, an anchor hook 200, a lever mechanism 3200, a transmission mechanism 40, and a release block 500, has a zinc layer attached to its surface by hot-dip galvanizing, and a waterproof paint layer is coated on the zinc layer surface.

[0074] Hot-dip galvanizing refers to the process of immersing metal components in molten zinc, forming a zinc-iron alloy layer and a pure zinc coating on their surface. This can be achieved using conventional hot-dip galvanizing processes, with the zinc layer thickness controlled within the range of 60-100 μm. Zinc provides electrochemical protection to the base metal through its sacrificial anode effect. Waterproof paint refers to a conventionally known organic protective coating, applied via spraying or brushing. The coating thickness can be controlled within the range of 80-150 μm, and the dense film layer prevents water vapor penetration.

[0075] Specifically, during the process of sequentially forming a hot-dip galvanized layer and a waterproof paint layer on the surface of the original release hook, the metal substrate is first pretreated by pickling and fluxing before being immersed in molten zinc at 450-480℃ to form a continuous and uniform zinc coating. The waterproof paint layer applied to the zinc layer effectively prevents dissolved oxygen and chloride ions in the river water from contacting the metal. The two protective layers work synergistically in the dynamic water flow environment. The zinc layer acts as the bottom layer of protection, slowing down the corrosion rate of the substrate, while the paint layer acts as the outer barrier, reducing zinc layer loss. This maintains the structural integrity of the release hook under long-term immersion conditions during the flood season.

[0076] Through the above technical solution, this application effectively prevents corrosive media in the river water from contacting the metal parts of the cable release hook, reduces the uniform corrosion rate of the zinc layer in the long-term immersion environment, inhibits the occurrence of local pitting corrosion and crevice corrosion, thereby extending the service life of the equipment under the immersion condition during the flood season and ensuring the normal operation of the cable release function after the flood season.

[0077] In summary, combining Figures 1 to 8As shown, the working principle of the rapid cable release hook device during the flood season is as follows: During the flood season, the rapid cable release hook is pre-treated with hot-dip galvanizing to form a galvanized layer on the outer surface of the hook and coated with waterproof paint to increase the corrosion resistance of the equipment; then, a first cover plate 600 and a second cover plate 700 made of stainless steel are installed at the top and bottom openings of the cable release hook using clips or bolts; then, the rapid cable release hook with the protective cover plates installed is completely immersed in the river water. After the flood season ends, the staff manually removes the first cover plate 600, exposing the internal lever mechanism 300. The lever mechanism 300 is pulled clockwise by the operating rod, and the release tongue 503 and the stop block body 501 are disengaged through the displacement of the transmission mechanism 400. At this time, the stop block body 501 presses on the cantilever part 202 at the outer end of the anchor hook 200 only by its own weight. Finally, under the pull of the cable, the cantilever 202 rotates upward around the first hinge axis 103 and pushes open the stop block body 501. After the stop block body 501 flips at a certain angle, the slot 502 at its bottom is arranged vertically, so that the end of the cantilever 202 continues to flip upward from the vertically arranged slot 502, and the hook part 201 at the other end flips downward, thereby achieving the purpose of releasing the cable on the hook part 201.
