Description

Technical Field

[0001] This utility model belongs to the field of gate construction technology, specifically relating to a fish-scale structure wear-resistant gate bottom plate. Background Technology

[0002] The bottom plate of the flood discharge and sediment flushing tunnel gate of the water conservancy project on the river with high sediment content is a key part under the action of water flow. It directly bears the impact and erosion of sediment particles, especially under the action of large bedload. In rivers with high sediment concentration or in the case of frequent sediment impact, traditional flat bottom plates or integral wear-resistant layers often have local perforations, cracks, peeling and local deep wear, resulting in frequent maintenance and shortened service life.

[0003] Existing technologies mostly improve wear resistance by integrally casting high wear-resistant concrete, laying wear-resistant steel plates or ceramic liners, and applying wear-resistant coatings. However, these methods have not fundamentally solved the problems of high impact, difficulty in repairing easily damaged parts, long downtime, and concentrated stress at single points. Utility Model Content

[0004] To address the aforementioned issues, this application provides a fish-scale structure wear-resistant gate base plate that improves wear resistance and ease of maintenance.

[0005] To achieve the above objectives, this utility model is realized through the following technical solution: A wear-resistant gate base plate with a fish-scale structure includes a base plate substrate. At least two rows of staggered fish-scale structure modules are provided on the base plate substrate. Each fish-scale structure module includes a base plate fixedly connected to the base plate substrate. The upper surface of the base plate has staggered surface buffer blocks, and the lower surface has evenly distributed bottom buffer blocks connected to the base plate substrate. The fish-scale structure modules have a uniform covering direction in the assembly direction, so that the fish-scale structure modules form a top-to-bottom flow-through overlapping relationship during operation, which is conducive to the discharge and cleaning of silt.

[0006] Preferably, a connector is provided on the side of the base plate facing the water flow direction. The connector includes an inner lining groove provided on the side of the base plate facing the water flow direction, an inner lining metal plate provided in the inner lining groove, an inner lining hole provided on the inner lining metal plate, and the inner lining hole communicating with a fixing screw hole provided on the base plate.

[0007] Preferably, the base plate on the side of the fixing screw hole near the surface buffer block is provided with a positioning hole that engages with the bottom buffer block; the width of the inner lining metal plate is 1 / 2 to 2 / 3 of the base plate; the diameter of the inner lining hole is smaller than the diameter of the fixing screw hole; under the action of high-speed water flow, the base plate bears a certain pressure, and at the same time, the base plate is fixed to the base plate through the inner lining hole and the fixing screw hole, and the base plate and the adjacent base plate can be fixedly connected by inserting the bottom buffer block into the positioning hole.

[0008] Preferably, the upper surface of the substrate is provided with a wear-resistant layer, which is one of polyurethane / polyurea, natural rubber, styrene-butadiene rubber, chloroprene rubber, nitrile rubber or composite materials thereof, and the lower surface is provided with an elastic buffer layer, which is one of polyurethane, rubber or elastic composite materials. The elastic buffer layer can absorb the impact energy brought by water flow impacting the substrate, thereby improving the service life of the substrate.

[0009] Preferably, the wear-resistant layer has a thickness of 10mm to 30mm; the elastic buffer layer has a thickness of 2mm to 15mm.

[0010] Preferably, the base plate is inclinedly disposed on the bottom plate base, and the base plate overlaps with the adjacent base plates on the upper and lower sides in sequence along the water flow direction.

[0011] Preferably, the inclination angle of the base plate on the bottom plate is 5 to 30°, which can guide the water flow and reduce the impact and erosion of the water flow on the fish scale structure module; the overlap width between the base plate and the adjacent base plates on the upper and lower sides is 5 to 100 mm.

[0012] Preferably, a sealing structure is provided at the connection between the base plate and the adjacent base plates on the left and right sides. The sealing structure is one of wear-resistant rubber sealing strip, epoxy grouting or prefabricated sealing gasket.

[0013] Preferably, the base plate has a length of 200–1000 mm, a width of 100–500 mm, and a thickness of 4–20 mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model installs a modular fish scale structure module on the base plate substrate. The fish scale structure module is covered on the base plate substrate in a staggered and overlapping manner, which can disperse the impact energy of particles in the water flow, thereby reducing the single-point wear of the fish scale structure module and effectively extending the service life of the base plate substrate. The fish scale structure module adopts a replaceable design and can be replaced individually according to maintenance needs, which can improve the maintenance convenience of this utility model.

[0015] (2) By installing staggered and overlapping fish scale structure modules on the base plate, this utility model can disperse the impact energy of particles in the water flow, reduce single-point contact stress, and enhance the convenience of local maintenance. Compared with the traditional flat plate base plate, this utility model can significantly reduce the wear rate and reduce the operation and maintenance cost.

[0016] (3) This utility model is constructed by overlapping and staggering several fish scale structure modules on the base plate substrate. The fish scale structure modules are connected by a detachable rigid connection and are equipped with sealing and elastic buffer measures. The fish scale structure modules can disperse impact and are easy to replace locally, which significantly improves wear resistance and maintenance convenience in high mud and sand environments.

Each fish scale structure module includes a base plate 1 fixedly connected to the base plate substrate. The upper surface of the base plate 1 is staggered with surface buffer blocks 2, and the lower surface is evenly distributed with bottom buffer blocks 6 connected to the base plate substrate.

[0074] A connector is provided on the side of the base plate 1 facing the water flow direction. The connector includes an inner lining groove on the side of the base plate 1 facing the water flow direction, and an inner lining metal plate 5 is provided in the inner lining groove. The inner lining metal plate 5 has an inner lining hole, which communicates with a fixing screw hole 4 provided on the base plate 1. The base plate 1 on the side of the fixing screw hole 4 near the surface buffer block 2 has a positioning hole 3 that engages with the bottom buffer block 6. The width of the inner lining metal plate 5 is 1 / 2 to 2 / 3 of the base plate 1. The diameter of the inner lining hole is smaller than the diameter of the fixing screw hole 4.

[0075] The installation and use of this utility model includes the following steps: S1. Prepare a suitable number of fish scale structure modules according to the gate installation requirements. The fish scale structure module includes a base plate 1, a surface buffer block 2 and a bottom buffer block 6 on both sides of the base plate 1, and a wear-resistant layer and an elastic buffer layer are respectively applied to both sides of the base plate 1.

[0076] S2. At the construction site, the base plate substrate is surface treated and positioned and marked, and the installation positions of the fixing screw holes 4 on each base plate 1 are marked.

[0077] S3. Install the fish scale structure modules along the base plate surface in a staggered, overlapping manner according to the planned arrangement and fix them with connectors. Specifically, install the first row of fish scale structure modules according to the marked fixing screw holes 4. Use expansion bolts to fix the first row of fish scale structure modules to the base plate through the fixing screw holes 4 and the inner lining holes on the inner lining metal plate 5. When installing the second row of fish scale structure modules, according to the installation position, insert the bottom buffer block 6 on the base plate 1 of the second row of fish scale structure modules into the positioning hole 3. Then use expansion bolts to fix the second row of fish scale structure modules to the base plate through the fixing screw holes 4 and the inner lining holes on the inner lining metal plate 5. Fix the remaining fish scale structure modules separately, ensuring that the overlapping direction faces the downstream of the water flow. Then use the sealing structure to seal the connection between the adjacent base plates 1 on the left and right sides.

[0078] S4. After completion, a water flushing test is performed; the water flows through the surface buffer block 2, which can disperse the impact energy of particles in the water flow and reduce single-point contact stress; the bottom buffer block 6 can absorb the impact energy brought by the water flow impacting the base plate 1, thereby improving the service life of the base plate 1; the fish scale structure module can be replaced individually after damage, which can enhance the convenience of local maintenance, significantly reduce the wear rate of the base plate and reduce the operation and maintenance costs.
