Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of water conservancy equipment, in particular to a pipe opening trash blocking device for a culvert. BACKGROUND
[0002] Irrigation channels can be divided into two types: open channels and culverts. Open channels are built on the ground and have a free water surface. Culverts are underground waterways with a closed periphery. In the prior art, a concrete pipe is generally used as the main body of the waterway, and no blocking device is installed at the pipe opening of the culvert. Debris can easily enter the pipe along with the water flow, affecting the water flow in the pipe and making it difficult to clean. The pipe can only be cleaned when the water flow in the pipe is stopped. If a steel mesh is used for blocking, the steel mesh can easily deform and enter the pipe. In addition, it is difficult to clean the debris wrapped around the steel mesh. If a wooden board is used for blocking, the wooden board can easily rot and be damaged. The broken pieces of the damaged wooden board can easily float away due to their low density. If an ordinary metal hole plate is used, the holes in the plate can easily be blocked by debris, and the water flow cannot be controlled. CONTENT OF THE UTILITY MODEL
[0003] To solve one of the technical problems in the prior art, the present application provides a pipe opening trash blocking device for a culvert, which can effectively block trash and prevent blockage, thereby ensuring the normal flow of irrigation water.

[0025] As shown in Figure 1 Figure 2 The application provides a gutter mouth trash blocking device, which comprises a fence plate 100 and a flange frame 200. The flange frame 200 is arranged outside the fence plate 100, and the flange frame 200 is connected and fixed with the fence plate 100. In some embodiments, the fence plate 100 and the flange frame 200 can be connected and fixed by welding. In other embodiments, the fence plate 100 and the flange frame 200 can be connected and fixed by bolts. In other embodiments, the fence plate 100 and the flange frame 200 can be integrally formed. A plurality of strip-shaped drainage holes 110 are formed on the fence plate 100. Figure 1 As shown in the drawings, after being installed to the pipe opening of the underdrain pipeline, the drain holes 110 are arranged vertically, wherein the length direction of the drain holes 110 is the first direction X, and the width direction of the drain holes 110 is the second direction Y, and the drain holes 110 are distributed staggeredly along the second direction Y. The flange frame 200 is provided with a plurality of mounting holes 240. The underdrain pipe opening trash arresting device of the present application designs the drain holes 110 as strips and arranges them vertically, which can effectively arrest trash, and the staggered distribution of the drain holes 110 greatly reduces the chance of being blocked, the water flow will not be interrupted, and the normal irrigation can be ensured.
[0026] In some embodiments of the present application, the fence plate 100 and the flange frame 200 are made of carbon steel, and the outer surfaces of the fence plate 100 and the flange frame 200 are provided with a rust-proof layer. Further, the rust-proof layer can be a zinc plating layer or a rust-proof paint sprayed on the surfaces of the fence plate 100 and the flange frame 200. Using carbon steel as the main material can ensure the strength of the fence plate 100 and the flange frame 200, and the rust-proof layer can make the fence plate 100 and the flange frame 200 have higher rust resistance and improve the service life of the fence plate 100 and the flange frame 200. In addition, it is easily conceivable that in other embodiments of the present application, the fence plate 100 and the flange frame 200 can also be made of other materials, such as plastic, rubber, stainless steel, etc., which can also have the same effect.
[0027] As shown in the drawings, Figure 2 In some embodiments of the present application, the thickness of the fence plate 100 is 5-10 mm, preferably 5 mm. The above structure can effectively ensure the strength of the fence plate 100 under the premise of saving materials as much as possible, and avoid the deformation of the fence plate 100 into the underdrain pipeline. When the material of the fence plate 100 is carbon steel or stainless steel, the plasma cutting method is preferably used to open the drain holes 110.
[0028] As shown in the drawings, Figure 1 In some embodiments of the present application, the length of the drain hole 110 is 50-150 mm, and the width of the drain hole 110 is 20-30 mm. Limiting the length and width of the drain hole 110 within the above range can effectively ensure the trash arresting effect, and the drain hole 110 is not easy to be blocked. It is easily understood that the length range and width range of the drain hole 110 introduced above are the preferred ranges in some embodiments of the present application, but in other embodiments of the present application, the length and width values of the drain hole 110 can also be selected not within the above range according to the actual situation.
[0029] As shown in the drawings, Figure 1 In some embodiments of the present application, the drain hole 110 includes a plurality of long holes 111 and a plurality of short holes 112, and the length of the long hole 111 is greater than the length of the short hole 112. Specifically, as shown in the drawings, Figure 1In some embodiments as shown, the length of the long hole 111 is 120 mm, and the length of the short hole 112 is 80 mm, and the length of the long hole 111 is greater than the length of the short hole 112. By setting at least two different specifications of the drainage holes 110, such as the long hole 111 and the short hole 112, the staggered distribution of the drainage holes 110 can be better achieved, and the space on the fence 100 can be better utilized.
[0030] As shown in Figure 1 and Figure 2 In some embodiments of the present application, a plurality of stainless steel nuts 300 are fixedly arranged on the fence 100. When the underground conduit is not in use and water flow is not needed, a circular baffle can be used to cover the fence 100, and then the stainless steel nuts 300 on the fence 100 are fixed by using a screw rod to protect the fence 100 and close the underground conduit.
[0031] As shown in Figure 1 and Figure 2 In some embodiments of the present application, the flange frame 200 includes a ring-shaped flange plate 210 and a connecting edge 220 arranged inside the flange plate 210, and the connecting edge 220 and the flange plate 210 form a 90-degree angle. The connecting edge 220 is used to connect and fix the fence 100, and the shape and size of the connecting edge 220 are adapted to the fence 100. In most cases, the connecting edge 220 and the fence 100 are both circular to maximize the utilization area; the outer diameter of the flange plate 210 is greater than the diameter of the underground conduit, and the diameter of the connecting edge 220 is slightly smaller than the diameter of the underground conduit, so that the connecting edge 220 and the fence 100 can be easily placed inside the underground conduit. In some embodiments, the diameter of the connecting edge 220 can be 5-10 mm smaller than the diameter of the underground conduit.
[0032] As shown in Figure 1 and Figure 2 In some embodiments of the present application, the width of the flange plate 210 arranged on the flange is 40-80 mm, for example, the width of the flange plate 210 can be set to 50 mm to facilitate the arrangement of the mounting hole 240 on the flange plate 210; the height of the connecting edge 220 is 40-80 mm, for example, the height of the connecting edge 220 can be set to 50 mm to facilitate the arrangement of the stainless steel nut 300 on the connecting edge 220.
[0033] As shown in Figure 1 and Figure 2As shown in some embodiments of the present application, the mounting holes 240 are arranged on the flange 210 and are evenly distributed in a circle. The trench pipe mouth trash arresting device has two fixing modes. In one of the fixing modes, the trench pipe mouth trash arresting device is placed at the pipe mouth position of the trench pipe, the flange 210 is tightly attached to the concrete beside the pipe mouth, expansion screws are used to pass through the mounting holes 240 and are connected to the inside of the concrete beside the pipe mouth, and the trench pipe mouth trash arresting device is fixed at the pipe mouth of the trench pipe.
