A reverse water delivery device for a canal and its construction method

Abstract

The invention discloses a canal reverse water delivery device and a construction method thereof. The canal reverse water delivery device comprises a baffle, a bottom plate is arranged at the bottom ofthe baffle, and the bottom plate is provided with supporting rods. The supporting rods are provided with grooves, rolling mechanisms are arranged in the grooves, and the rolling mechanisms are provided with connecting rods. The connecting rods are provided with first fixed blocks, the first fixed blocks are provided with first arc-shaped grooves and limiting rods, and the first arc-shaped groovesare provided with rolling balls. The rolling balls are connected with second arc-shaped grooves and second fixed blocks, the second arc-shaped grooves are formed in the second fixed blocks, and a locating ring is arranged between the second fixed blocks. The locating ring is provided with a water collecting hopper, the locating ring rotates along the rolling balls, a filtering mechanism is arranged in the water collecting hopper, and a guide plate is arranged between the supporting rods. The construction method comprises the following steps of 1) preparation work conduction; 2) mounting of the delivery device; 3) fixing of the water delivery device; 4) water delivery with the device; and 5) water collecting hopper cleaning. According to the canal reverse water delivery device and the construction method thereof, the problem that when a downstream canal conveys water to the upstream portion, sediment is likely to be mixed, and delivery is influenced is solved.

Description

technical field [0001] The invention specifically relates to a canal reverse water delivery device and a construction method thereof. Background technique [0002] Canal irrigation is the basic method of crop irrigation. In the past, canal irrigation was artificially used to block or release water in the canal. Later, with the development of the times, the canal was made of concrete, and the sluice was used to realize the water canal during the irrigation process. The blockage of Lishui, in some canals with large height difference, when the water storage in the upstream is large, the upstream water flows downward, and when the upstream water is insufficient, we usually use the pump to pump water, and the pump When pumping water, it is easy to bring silt in the water, which affects the operating efficiency of the pump. After long-term use, it is easy to cause silt accumulation and affect water delivery. Contents of the invention [0003] The purpose of the present inventio...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a reverse water delivery device and its construction method for a number of deficiencies in the prior art, which solves the problem of upstream water flow in some canals with large height differences when the water storage capacity in the upstream is large. When the upstream water is insufficient, we usually use a water pump to pump water. When the water pump pumps water, it is easy to bring the sediment in the water, which affects the operation efficiency of the water pump. It is easy to cause mud after long-term use.
