Description

Sand-proof gravel river channel irrigation gate

Technical Field

The invention relates to the technical field of gates, in particular to a sand-prevention gravel river channel irrigation gate.

Background

The mode of mainly adopting the flood irrigation among the traditional agricultural production irrigates the farmland, along with the development of times, has developed and has handled modes such as drip irrigation, sprinkling irrigation at present, but because drip irrigation, sprinkling irrigation need cloth pipe in advance, and the farmland needs often to dig and go agricultural machine, therefore drip irrigation, sprinkling irrigation still have limited in agricultural production uses, flood irrigation still is agricultural irrigation's main means at present.

When flood irrigation is carried out, gaps are dug out on ridges, canal water is introduced into farmlands, soil is used for blocking the gaps of the ridges after the water level meets requirements, the operation is time-consuming and labor-consuming, along with the development of times, at present, gates are often arranged on canals to realize the control of water blocking and water flow, compared with the traditional mode, the gates are easier to operate and can better control the water flow, but when the gates are opened for flood irrigation, foreign matters such as broken stones and gravels in river channels can easily enter the sealing positions of the gate plates and the gates along the water flow, because the stroke of the gates is fixed, the gates can not be completely closed due to the foreign matters when the gates are closed, the problems of water seepage and water leakage can occur, the sealing strips of the gates can be damaged even seriously, the service life of the gates is shortened, if the existing gates are improved, a novel gate is developed, the service life of the gates is prolonged, ensuring the sealing performance of the gate has positive significance.
