Anti-blocking buckle of infiltrating irrigation pipe

Abstract

The invention provides an anti-blocking buckle of an infiltrating irrigation pipe. The problem that in the prior art, silt and capillary roots cause blocking easily is solved. The anti-blocking buckle comprises two symmetric arch pieces, the two arch pieces are in butt joint to form a pipe-shaped part for coating the infiltrating irrigation pipe, flow grooves for water flow to pass through are formed in the inner walls of the arch pieces, water outlet channels are formed in the edges of the arch pieces, the flow grooves are communicated with the water outlet channels, the orthographic projection, on the anti-blocking buckle, of a water outlet of the infiltrating irrigation pipe is located in the flow grooves, anti-blocking flexible films are fixedly suspended above the flow grooves and correspond to the water outlet in the infiltrating irrigation pipe, and the area of the anti-blocking flexible films is larger than that of the water outlet in the infiltrating irrigation pipe; under normal pressure, the anti-blocking flexible films do not make contact with the bottoms of the flow grooves or the water outlet. By means of the design of the anti-blocking flexible films, the anti-blocking buckle can play a role in flow blocking during infiltrating irrigation and can prevent the situation that when water supply is cut off, negative pressure is formed in the infiltrating irrigation pipe to suck the silt and capillary roots into the anti-blocking buckle to cause clogging.

Description

technical field [0001] The invention belongs to the field of agricultural irrigation and water delivery, in particular to an anti-blocking buckle for seepage irrigation pipes. Background technique [0002] Infiltration irrigation is an underground water-saving irrigation method. Different from other irrigation methods, it is transferred from the surface to the ground for irrigation, and some people call it subsurface drip irrigation. It irrigates by burying a unique plastic pipe underground. This plastic pipe is called a seepage pipe. According to the needs of the farmers, small holes are made at intervals on the seepage pipe. When the pipe is filled with water, The small hole will gradually ooze out from the small hole like sweating. Through this structure, water and fertilizer can be sent directly to the underground root zone of the crop, and the plant only needs to absorb it directly. The advantage of infiltration irrigation is that it reduces the evaporation of water o...

AI Technical Summary

Problems solved by technology

[0004] Due to the existence of capillary roots and fine soil underground, the seepage holes of the flow channel grooves of the above-mentioned short-seepage pipes will still enter the capillary roots and soil under the action of negative pressure, and further enter the holes in the wall of the water delivery pipe. Over time, there will still be The problem of blockage, therefore, the above structure only delays the time of blockage, and does not fundamentally solve the problem of blockage
