Description

TECHNICAL FIELD

[0001] The application relates to the technical field of drainage ditches, in particular to a siltation-preventing ditch for farmland irrigation. BACKGROUND

[0002] In the related art, a ditch structure for farmland irrigation is disclosed in Patent No. CN217517502U, which comprises a ditch body, an anti-flood irrigation mechanism, a cleaning mechanism and a water seepage prevention mechanism. The anti-flood irrigation mechanism is located at the outer end of the ditch body, the cleaning mechanism is located inside the ditch body, and the water seepage prevention mechanism is located at the bottom of the ditch body. The cleaning mechanism comprises a support plate, a guide rod, a spring and a cleaning brush. The support plate is fixedly installed below the ditch body, the number of support plates is several, the support plates are arranged at equal intervals, the guide rod is fixedly installed at the outer end of the support plate, and the guide rod is symmetrically distributed. The ditch structure for farmland irrigation prevents siltation by setting the cleaning mechanism. When water flows through the ditch body, the power generated by the water flow drives the cleaning brush to slide back and forth along the guide rod. Therefore, the cleaning brush can scrape off the silt deposited at the bottom, preventing siltation and facilitating the cleaning of the ditch.

[0003] In the above-mentioned technology, the power generated by the water flow drives the cleaning brush to slide back and forth along the guide rod. The spring can reset the cleaning brush when the water flow is relatively slow. In this process, the cleaning brush directly contacts the inner cavity of the ditch body, which hinders the flow direction of the water flow, thereby reducing the flow rate of the water flow and further reducing the efficiency of irrigation of farmland. CONTENT OF THE UTILITY MODEL

[0004] To solve the current situation that the power generated by the water flow drives the cleaning brush to slide back and forth along the guide rod, the spring can reset the cleaning brush when the water flow is relatively slow, and in this process, the cleaning brush directly contacts the inner cavity of the ditch body, which hinders the flow direction of the water flow, thereby reducing the flow rate of the water flow and further reducing the efficiency of irrigation of farmland, the application provides a siltation-preventing ditch for farmland irrigation.

[0005] The siltation-preventing ditch for farmland irrigation provided by the application adopts the following technical solution: a prefabricated concrete drainage ditch, a support table arranged at the middle position of the drainage ditch, a drainage seat arranged at the upper end surface of the support table, mud guards arranged on both sides of the drainage seat, mud discharge holes uniformly arranged on the mud guards, a mud settling cavity arranged at the lower end surface of the mud guards, and a mud discharge port arranged at the mud settling cavity.

[0007] Optionally, the drainage seat is provided with a trapezoidal cross section, and the drainage seat comprises a planar water guide platform, a first inclined water guide platform arranged on one side of the planar water guide platform, and a second inclined water guide platform arranged on the other side of the planar water guide platform, the first inclined water guide platform and the second inclined water guide platform are arranged in a mirror image, and the first inclined water guide platform and the second inclined water guide platform are integrally formed with the planar water guide platform.

[0008] By adopting the technical scheme, when water flows through the drainage seat, the sludge on the planar water guide platform flows to both sides due to the impact of the water flow, and the first inclined water guide platform and the second inclined water guide platform guide the flow direction of the sludge.

[0009] Optionally, the mud guard is provided in a "U" shape, and the sludge discharge holes are uniformly arranged on the lower end surface of the mud guard.

[0010] By adopting the technical scheme, the sludge is prevented from flowing out through both sides of the mud guard.

[0011] Optionally, each sludge discharge hole is provided in a rectangular shape, and the rectangular sludge discharge holes are arranged at equal distances.

[0012] By adopting the technical scheme, the sludge on the mud guard falls into the sludge settling chamber due to its self weight through the sludge discharge holes.

[0013] Optionally, the sludge falling port is arranged in the length direction of the sludge settling chamber, and the inner diameter of the sludge falling port is greater than the inner diameter of the sludge discharge hole.

[0014] By adopting the technical scheme, the sludge falling port facilitates the sludge in the sludge settling chamber to fall onto the vegetation surface, so that the sludge is recycled.

[0015] Optionally, the support platform further comprises a first limiting groove arranged on one side of the support platform and a second limiting groove arranged on the inner wall of the drainage ditch, the first limiting groove and the second limiting groove facilitate the installation of the mud guard, and the upper end surface of the first limiting groove is arranged on the same horizontal plane as the lower end surfaces of the first inclined water guide platform and the second inclined water guide platform.

[0016] By adopting the above technical solution, the sludge falling through the first and second inclined water guide platforms can quickly fall into the mud baffle due to its own weight.

[0017] Optionally, it also includes a transition plate disposed on the inner wall of the mudguard and adjacent to the first inclined water guide platform and the second inclined water guide platform, the transition plate being disposed along the length direction of the mudguard and being inclined.

[0018] By adopting the above technical solution, the transition plate can buffer the falling speed of the sludge entering the mud baffle through the first inclined water guide platform and the second inclined water guide platform, thus preventing the sludge from splashing everywhere.

[0019] In summary, this application includes the following beneficial technical effects:

Due to the impact of the water flow, the sludge falls into the mud baffles on both sides of the drainage seat. The sludge on the mud baffles falls into the sedimentation chamber through the mud discharge hole due to its own weight. The sludge in the sedimentation chamber falls onto the vegetation surface through the mud discharge port.

[0021] 2. It also includes a transition plate disposed on the inner wall of the mudguard and adjacent to the first inclined water guide platform and the second inclined water guide platform. The transition plate facilitates the buffering of the falling speed of the sludge entering the mudguard through the first inclined water guide platform and the second inclined water guide platform, thereby preventing the sludge from splashing everywhere.
