Description

Technical Field

[0001] This utility model relates to the field of dock gates, and in particular to a dock gate buttress device with buffering and energy absorption function. Background Technology

[0002] Dock doors, as auxiliary devices for ships entering and leaving docks, are used to prevent seawater from outside the dock from entering. Dock doors are subject to significant pressure; if their pressure resistance is inadequate, they may deform or crack, allowing seawater to enter and compromising safety within the dock.

[0003] To address the aforementioned issues, a search revealed, for example, a dock pressure-resistant gate disclosed in patent publication number CN211642548U. This gate includes a gate body with multiple spaced reinforcing bars along its inner sides and a protrusion at the center of its outer side. The gate body comprises a reinforced concrete layer, a first steel plate layer, and a second steel plate layer. The first steel plate layer encloses the reinforced concrete layer, and the second steel plate layer encloses the first steel plate layer. By providing multiple spaced reinforcing bars along the inner sides of the gate body, the strength of the gate body is increased. The protrusion at the center of the outer side of the gate body, with multiple protrusions on both sides of the protrusion, enhances the gate's resistance to seawater impact, thereby improving the dock gate's pressure resistance.

[0004] Based on the above search and combined with existing technology, it was found that existing dock gate structures similar to those disclosed above lack effective buffering functions, causing the dock gates to be subjected to severe impacts from seawater for extended periods, making them prone to deformation or breakage. Utility Model Content

[0005] The core of this invention lies in solving the problem of the lack of effective buffering function in existing dock gate structures through the coordinated arrangement of an extension block, a buffer cavity, an inner pressure plate, a return spring, a transmission slide column, and an outer pressure plate. This also ensures the stability of its buffering effect.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A dock gate buttress device with buffering and energy absorption function includes a buttress plate integrally installed on the dock gate plate on the outer surface of the dock, an extension block integrally installed on the side of the buttress plate away from the dock gate plate, and a buffer cavity installed on the inner side of the extension block. An inner pressure plate is provided on the inner side of the buffer chamber. The inner pressure plate is horizontally slidably attached to the inner wall of the buffer chamber. An outer pressure plate is provided on the side of the expansion block away from the dock gate plate. A transmission slide column that slides through the expansion block is horizontally fixed between the outer pressure plate and the inner pressure plate. A return spring is horizontally fixed between the inner pressure plate and the inner wall of the buffer chamber. The expansion block has a first water inlet / outlet hole connected to the buffer chamber on the side closest to the outer pressure plate, and a second water inlet / outlet hole connected to the buffer chamber on the side furthest from the outer pressure plate.

[0008] By using the combination of extension blocks, buffer chambers, inner pressure plates, return springs, transmission slides, and outer pressure plates, the slow extrusion of seawater can buffer the dock gate plate, reducing the violent impact on the dock gate plate, thereby better protecting the dock gate plate and extending its service life.

[0009] Furthermore, a flow guide is fixed to the side end of the extension block. The flow guide is connected to the second water inlet and outlet hole. The flow guide extends toward the side away from the dock gate plate, and a third water inlet and outlet hole is provided on the side end of the flow guide near the outer pressure plate.

[0010] Furthermore, the second water inlet and outlet holes are located on the upper and lower sides of the expansion block, and two diversion hoods are provided, with the two diversion hoods respectively fixed to the upper and lower ends of the expansion block.

[0011] Furthermore, a protective mesh frame is fixed to the end face of the extension block away from the buttress plate. The protective mesh frame is used to cover the gap between the outer pressure plate and the extension block.

[0012] Furthermore, the rectangular array of the end face of the extension block away from the buttress has multiple reinforcing protrusions.

[0013] Furthermore, multiple reinforcing protrusions have movably mounted stress relief balls on their end faces away from the extension blocks.

[0014] Compared with existing technologies, the advantages of this utility model are: (1) This solution uses an extension block, a buffer chamber, an inner pressure plate, a return spring, a transmission slide column, and an outer pressure plate in combination. When seawater impacts the outer pressure plate, the outer pressure plate moves the inner pressure plate toward one side of the dock gate plate through the transmission slide column. The inner pressure plate then squeezes the seawater in the buffer chamber near the dock gate plate outward through the second inlet and outlet holes. This process can play a certain buffering role. This buffering role absorbs the impact energy and reduces the violent impact on the dock gate plate, thereby better protecting the dock gate plate and extending its service life.

[0015] (2) By setting up the diversion hood, when the dock gate is subjected to seawater, the seawater can enter the diversion hood more smoothly through the second inlet and outlet holes and spray outward from the third inlet and outlet holes. The water flow sprayed from the third inlet and outlet holes can vertically impact the seawater that is impacting laterally, thereby mitigating the lateral impact of seawater on the dock gate to a certain extent.

[0016] (3) This scheme has movably installed unloading balls on the end faces of multiple reinforcing protrusions away from the extension blocks. When the unloading balls are impacted by seawater (especially when they are impacted by an impact that is not perpendicular to the dock gate), they can rotate, thereby playing a role in unloading.

[0019] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0020] First implementation method: Please see Figures 1-4 A dock gate buttress device with buffering and energy absorption function includes a buttress plate 2 integrated on the outer surface of the dock gate plate 1. The dock gate plate 1 adopts a conventional box-shaped steel structure, which is only a simplified illustration in the figure.

[0021] The expansion block 3 is integrally provided on the side of the buttress plate 2 away from the dock gate plate 1. A buffer cavity is provided on the inner side of the expansion block 3. An inner pressure plate 4 is provided on the inner side of the buffer cavity. The inner pressure plate 4 is horizontally slidably attached to the inner wall of the buffer cavity. An outer pressure plate 6 is provided on the side of the expansion block 3 away from the dock gate plate 1. A transmission slide 5 that slides through the expansion block 3 is horizontally fixed between the outer pressure plate 6 and the inner pressure plate 4. A return spring 11 is horizontally fixed between the inner pressure plate 4 and the inner wall of the buffer cavity. A first water inlet / outlet hole 301 connected to the buffer cavity is provided on the side of the expansion block 3 near the outer pressure plate 6. A second water inlet / outlet hole 302 connected to the buffer cavity is provided on the side of the expansion block 3 away from the outer pressure plate 6.

[0022] Based on the above-mentioned arrangement of the expansion block 3, buffer cavity, inner pressure plate 4, return spring 11, transmission slide 5 and outer pressure plate 6, when seawater impacts the outer pressure plate 6, the outer pressure plate 6 moves the inner pressure plate 4 towards one side of the dock gate plate 1 through the transmission slide 5. The inner pressure plate 4 uses the inner pressure plate 4 to squeeze the seawater in the buffer cavity near the dock gate plate 1 outward through the second inlet and outlet holes 302. This process can play a certain buffering role, which absorbs the impact energy and reduces the violent impact on the dock gate plate 1, thereby better protecting the dock gate plate 1 and extending its service life.

[0023] When the impact of the seawater weakens or disappears, the inner pressure plate 4 is reset by the elastic force of the return spring 11. During this process, the external seawater re-enters the buffer chamber near the dock gate plate 1 through the second water inlet / outlet hole 302, preparing for the next buffering.

[0024] Of course, in order to extend the service life of the return spring 11, the return spring 11 is preferably made of 316L stainless steel, which is not easily corroded by seawater.

[0025] Among them, the end face of the extension block 3 away from the buttress 2 is fixed with a protective mesh frame 8. The protective mesh frame 8 is used to cover the gap between the outer pressure plate 6 and the extension block 3, which can effectively prevent garbage in the seawater from entering the gap between the outer pressure plate 6 and the extension block 3, causing the buffering effect to fail.

[0026] Furthermore, the rectangular array on the end face of the extension block 3 away from the buttress plate 2 has multiple reinforcing protrusions 9. These reinforcing protrusions 9 enhance the structural strength of the end face of the extension block 3, making it less prone to deformation or damage when subjected to the impact of seawater and various external forces. Simultaneously, the distribution of the rectangular array of multiple reinforcing protrusions 9 can also disperse stress to a certain extent, evenly distributing the force concentrated on the extension block 3 to each reinforcing protrusion 9, further improving the stability and reliability of the entire device and ensuring the normal functioning of the buffering and energy absorption function.

[0027] Second implementation method: Based on the first embodiment, a diversion hood 7 is fixed to the side end of the extension block 3. The diversion hood 7 is connected to the second water inlet / outlet hole 302. The diversion hood 7 extends toward the side away from the dock gate plate 1, and a third water inlet / outlet hole 701 is provided on the side end of the diversion hood 7 near the outer pressure plate 6.

[0028] More specifically, the second water inlet and outlet holes 302 are located on the upper and lower sides of the expansion block 3, and there are two diversion covers 7, which are respectively fixed to the upper and lower ends of the expansion block 3.

[0029] When the dock gate is subjected to seawater, the seawater can more smoothly enter the diversion shroud 7 through the second inlet / outlet hole 302 and be sprayed outward from the third inlet / outlet hole 701, such as... Figure 4As shown, the water jet from the third inlet / outlet port 701 (such as...) Figure 4 The vertical dashed line and thickened arrow in the image indicate that vertical impact can counteract the lateral impact of seawater (such as...). Figure 4 (As shown by the bolded arrow in the horizontal dashed line) to conduct vertical impact, thereby mitigating the lateral impact of seawater on the dock gate to some extent.

[0030] The third implementation method: Based on the first and second embodiments, each of the reinforcing protrusions 9 has a movably mounted stress relief ball 10 on its end face away from the extension block 3. When the stress relief ball 10 is impacted by seawater (especially when impacted by an impact not perpendicular to the dock gate), it can rotate, thereby relieving stress. Furthermore, the surface of the stress relief ball 10 is a smooth curved surface design, which further reduces the resistance generated by seawater impact, making the stress relief ball 10 rotate more flexibly. In addition, the stress relief ball 10 is made of high-strength, corrosion-resistant material, and can maintain good performance and is not easily damaged even under long-term seawater erosion and impact.

[0031] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
