Self-bucket-tipping type irrigation water amount measuring device

Abstract

The invention discloses a self-bucket-tipping type irrigation water amount measuring device. The device comprises a water passing tank, a tipping bucket, a water inlet gate and a measuring system usedfor measuring the irrigation frequency of the tipping bucket; the tipping bucket is rotatably connected with the water passing tank, the water inlet side of the water passing tank is provided with afirst opening matched with the water inlet gate, the water outlet side of the water passing tank is provided with a second opening matched with the tipping bucket, the front end of the tipping bucketextends out of the second opening, and the water inlet gate is slidingly connected with the first opening; in the water inlet state, the water inlet gate is in a low position so that water in an irrigation channel can enter the tipping bucket, the tipping bucket is transversely distributed in the water passing tank, the center of gravity of the tipping bucket is gradually transferred towards the front end of the tipping bucket along with the increase of the water inlet amount, when the water level in the tipping bucket reaches a calibration value, the tipping bucket tips over clockwise under the action of the gravity of the tipping bucket, the water inlet gate is synchronously driven to ascend to separate the irrigation channel from the tipping bucket, and the water in the tipping bucket flows into farmland. According to the self-bucket-tipping type irrigation water amount measuring device, intermittent and equivalent water passing is achieved through a balanced bucket tipping mechanism, and the irrigation water amount in the farmland is accurately measured.

Description

technical field [0001] The invention relates to a self-tipping bucket type irrigation water metering device, which belongs to the technical field of irrigation water metering devices. Background technique [0002] my country is a typical agricultural water-deficient country. The rational use of water resources has always been a major issue affecting the development of my country's agriculture and the improvement of people's living standards. How to improve the utilization efficiency of agricultural irrigation water and rationally allocate water resources has become the bottleneck of my country's agricultural development. At present, my country's agricultural irrigation generally adopts extensive and inefficient management forms, and the waste of water resources is huge. Most of the agricultural irrigation water is charged by area or by mu, rather than by actual water consumption. This has caused people's awareness of water conservation Not strong, willful waste of water resou...

Problems solved by technology

[0004] The measurement of irrigation water is a basic and key technology. Most of the traditional Parshall flume, U-shaped flume and other water metering devices are suitable for large-flow ditches, and the equipment is relatively large and complicated, and it is not suitable for irrigation areas. Metering of small excess water in a single farmland

Other types of precise flow metering equipment (such as ultrasonic flowmeters, infrared flowmeters) have high flow metering accuracy, but the investment cost is high, the installation is complicated, the maintenance cost is high, and the use conditions are relatively harsh. It is very easy to be damaged by water impact, sand, weather and other factors
