An inclination-type water metering device suitable for irrigation ditches

Abstract

The invention is an inclination-type water metering device suitable for irrigation ditches, comprising a water tank, a water retaining device, an angle sensor and a controller; On the top of the water tank, the angle sensor is connected to the controller through the signal line, and the angle sensor is connected to the rotating shaft; the angle sensor can convert the rotation angle of the water retaining door into a digital pulse signal and input it to the controller. Advantages: 1) Good real-time response, and high measurement accuracy for unstable water flow; 2) The opening degree of the water retaining door can be adjusted under different flow rates to adapt to use in ditches with different flow rates; 3) It can guarantee Compared with ditches, it has better flow capacity; 4) Strong adaptability, and debris such as sediment in the water flow will not affect the accuracy of measurement; 5) It is easy to realize remote network automatic control; 6) Simple structure, convenient installation and low cost, It is suitable for large-scale promotion and use.

Description

technical field [0001] The invention relates to an inclination-type water metering device suitable for irrigation ditches, which belongs to the technical field of farmland water conservancy. Background technique [0002] Water is the lifeblood of agriculture. With the increase of farmland irrigation facilities and the continuous expansion of agricultural area in my country, coupled with the serious waste of agricultural water, saving water resources and establishing a strict water resource management system have become urgent tasks. However, the extensive and inefficient use of agricultural irrigation in my country is generally used. At the same time, there are still problems such as the difficulty of paying water fees and the imperfect system of paid use of water resources, which is not conducive to the improvement of irrigation efficiency. For example, there are still quite a few irrigation districts that still collect water fees by area or mu, rather than by water consump...

AI Technical Summary

Problems solved by technology

However, these water measuring facilities are not perfect, such as water measuring weirs, water measuring tanks and other devices with low accuracy; large water flow metering devices require a large amount of capital investment and occupy a lot of farmland; high-tech instruments require high maintenance and calibration, and technical Lack of professional training for personnel; it is difficult to collect information in medium and large irrigation areas, and the degree of automation is low, etc.
