Farmland irrigating device for water conservancy project

Abstract

The invention discloses a farmland irrigating device for a water conservancy project. The farmland irrigating device comprises farmland and an irrigation ditch, a field dam is arranged between the farmland and the irrigation ditch, an irrigation opening is formed in the field dam, mounting frames located above the irrigation opening are mounted on the field dam, and a protection fence is mounted in the irrigation opening. Sliding grooves are formed in the two side walls of the irrigation opening, water fenders are mounted in the sliding grooves, two pairs of mounting frames are arranged, and amounting shaft is mounted at the tops of each pair of mounting frames. Rollers are mounted on the mounting shafts, the tops of the fenders are connected with one end of a pull rope, the pull rope passes through the rollers, a hollow floating block is mounted at the other end of the pull rope, and the weight of the hollow floating block is larger than that of the water fenders. The protection fence is mounted on an end opening of the water inlet end of the irrigation opening, debris can be blocked out of the irrigation opening, and the debris is prevented from blocking the irrigation opening.According to the device, the farmland irrigation opening can be automatically opened and closed through the buoyancy force of water, and the aim of automatic farmland irrigation is achieved. Electricdrive is not needed, and the farmland irrigating device is convenient to mount and use, low in manufacturing cost and suitable for use and popularization.

Description

technical field [0001] The invention relates to an irrigation device, in particular to a farmland irrigation device for water conservancy projects, and belongs to the technical field of water conservancy projects. Background technique [0002] Farmland water conservancy is a water conservancy engineering measure aimed at increasing agricultural production, that is, through the construction and use of various water conservancy engineering measures, it can adjust and improve the water condition of farmland and regional water conservancy conditions, improve the ability to resist natural disasters, promote a virtuous cycle of the ecological environment, and make it healthy. conducive to the production of crops. At present, the state has invested a large amount of funds in strengthening the construction of farmland water conservancy infrastructure in order to improve agricultural production. The convenience of farmland irrigation has been greatly improved, water resources have b...

AI Technical Summary

Problems solved by technology

However, there are many defects in the operation and management of the existing farmland water conservancy and irrigation facilities.

When irrigating, it is necessary to manually open the irrigation ports of each farmland one by one, wasting a lot of time and manpower, or use automation equipment to control the opening and closing of irrigation ports, but the cost of automation equipment is high, wiring and power supply are required, and subsequent maintenance is very troublesome
