Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a water conservancy engineering fence. Background Technology

[0002] A trash rack is a frame structure installed in front of the water intake. It is mainly used to block debris such as aquatic plants and driftwood carried by the water flow, protecting hydraulic structures and equipment from damage. Trash racks are typically installed in front of the water intake of hydroelectric power stations, pumped storage power stations, and pumping stations to prevent debris from entering the waterway and damaging equipment such as turbines and pumps.

[0003] Currently, most existing water conservancy project fences are made of metal, mainly consisting of a frame and railings, with a layer of metal mesh covering the entire fence surface. However, the railings and frame of this type of fence are fixed by welding, resulting in a completely fixed structure at the factory. This leads to a large size of the entire fence during transportation, making it inconvenient and difficult to transport. If bolts are used for assembly, the efficiency of on-site assembly is relatively low. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water conservancy engineering fence.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water conservancy engineering fence, comprising two horizontal plates, two vertical poles, and a barrier net. The two vertical poles are located between the two horizontal plates. Each of the two horizontal plates is fixed with a snap-fit ​​assembly near the vertical pole. Each vertical pole has an installation groove at both ends for snapping into the snap-fit ​​assembly, and the vertical pole is fixedly connected to the horizontal plate through the snap-fit ​​assembly. Multiple railings are vertically fixed between the two horizontal plates, and a positioning plate is horizontally fixed between the two vertical poles. The multiple railings pass through the positioning plate. Each of the two horizontal plates has an installation assembly for fixing the barrier net on its side.

[0006] Furthermore, the snap-fit ​​assembly includes a mounting block fixed to the surface of the horizontal plate, and the mounting block is inserted into the mounting groove at the end of the upright. A snap-fit ​​hole is provided on one side of the mounting groove. A groove is provided on the side of the mounting block near the snap-fit ​​hole, and a spring is fixedly connected to the inner wall of the groove. A snap-fit ​​tooth is fixedly connected to the other end of the spring, and the end of the snap-fit ​​tooth away from the spring snaps into the snap-fit ​​hole.

[0007] Furthermore, each of the two horizontal plates has multiple insertion holes on adjacent sides for inserting railings.

[0008] Furthermore, positioning blocks are fixed at both ends of the positioning plate, and positioning grooves for inserting positioning blocks are provided on the side walls of both uprights.

[0009] Furthermore, the positioning plate has multiple through holes for the railing to pass through.

[0010] Furthermore, the installation assembly includes a pressure plate and a screw fixed to the surface of the horizontal plate. Both the pressure plate and the intercepting net have through holes for the screw to pass through. A nut is connected to one end of the screw that passes through the intercepting net and the pressure plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model is a water conservancy engineering fence, which is equipped with two horizontal plates, two vertical poles, several railings and a barrier net. The two vertical poles are fixedly connected to the two horizontal plates at both ends by installation components. The two horizontal plates press and fix the several railings.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, a water conservancy engineering fence is disclosed, comprising two horizontal plates 1, two vertical poles 2, and a barrier net 5. The two vertical poles 2 are located between the two horizontal plates 1. Each horizontal plate 1 is fixed with a snap-fit ​​component 7 near the vertical pole 2. Both ends of the vertical pole 2 are provided with mounting grooves 21 for snapping into the snap-fit ​​component 7, and the vertical pole 2 is fixedly connected to the horizontal plate 1 through the snap-fit ​​component 7. Multiple railings 4 are vertically fixed between the two horizontal plates 1, and a positioning plate 3 is horizontally fixed between the two vertical poles 2. The multiple railings 4 pass through the positioning plate 3. The sides of both horizontal plates 1 are provided with mounting components 6 for fixing the barrier net 5.

[0024] The snap-fit ​​assembly 7 includes a mounting block 71 fixed to the surface of the horizontal plate 1, and the mounting block 71 is inserted into the mounting groove 21 at the end of the upright 2. A snap-fit ​​hole 22 is provided on one side of the mounting groove 21. A groove 72 is provided on the side of the mounting block 71 near the snap-fit ​​hole 22, and a spring 73 is fixedly connected to the inner wall of the groove 72. A snap-fit ​​tooth 74 is fixedly connected to the other end of the spring 73, and the end of the snap-fit ​​tooth 74 away from the spring 73 snaps into the snap-fit ​​hole 22.

[0025] When assembling the upright 2 and the horizontal plate 1, the mounting block 71 on the horizontal plate 1 is directly inserted into the mounting groove 21 on the upright 2. During this process, the retaining teeth 74 are first pressed back into the groove 72 by the side wall of the mounting groove 21. After the mounting block 71 is fully inserted into the mounting groove 21, the spring 73 presses the retaining teeth 74 into the retaining hole 22, thereby fixing the mounting block 71 inside the mounting groove 21, thus achieving the fixed assembly between the upright 2 and the horizontal plate 1. When it is necessary to separate the upright 2 and the horizontal plate 1, the retaining teeth 74 are pressed apart from the retaining hole 22, and the mounting block 71 can be pulled out from the mounting groove 21.

[0026] Both horizontal plates 1 have multiple insertion holes 101 on adjacent sides for inserting railings 4.

[0027] When assembling the railing 4 between the two horizontal plates 1, simply insert both ends of the railing 4 into the insertion holes 101 on the horizontal plate 1.

[0028] Positioning blocks 31 are fixed at both ends of the positioning plate 3, and positioning slots 23 for inserting positioning blocks 31 are opened on the side walls of the two uprights 2.

[0029] The positioning plate 3 can be fixed by inserting the positioning blocks 31 at both ends of the positioning plate 3 into the positioning grooves 23 on the side walls of the two uprights 2.

[0030] The positioning plate 3 has multiple through holes 32 for the railing 4 to pass through.

[0031] By setting the positioning plate 3, the railing 4 can be positioned after passing through the through hole 32, which is beneficial for the installation of the railing 4.

[0032] The mounting assembly 6 includes a pressure plate 61 and a screw 62 fixed to the surface of the horizontal plate 1. The pressure plate 61 and the intercepting net 5 are both provided with through holes for the screw 62 to pass through. A nut 63 is connected to one end of the screw 62 that passes through the intercepting net 5 and the pressure plate 61.

[0033] When installing the interception net 5, first attach the interception net 5 to the sides of the two horizontal plates 1, and let the screw 62 pass through the perforation on the interception net 5. Then, put the pressure plate 61 on the screw 62, and then screw the nut 63 on the surface of the screw 62. Use the pressure plate 61 to press and fix the interception net 5.

[0034] Working principle: When assembling the fence, first insert the positioning blocks 31 at both ends of the positioning plate 3 into the positioning slots 23 on the two uprights 2. Then, assemble one end of the two uprights 2 with one of the horizontal plates 1 by inserting the snap-fit ​​component 7 on the horizontal plate 1 into the mounting slot 21 on the upright 2. After assembly, install the railings 4 by passing multiple railings 4 through the through holes 32 of the positioning plate 3 and inserting them into the insertion holes 101 of the installed horizontal plate 1. After the railings 4 are installed, assemble another horizontal plate 1 at the other end of the two uprights 2. After the above assembly is completed, cover the sides of the two horizontal plates 1 with the interception net 5 and fix the interception net 5 with the mounting component 6. If the interception net 5 is damaged or a single railing 4 is deformed, the fence can be disassembled and the interception net 5 replaced or the damaged railing 4 replaced individually.
