Energy-saving method of sprinkling irrigation graded pumping and frequency conversion in slope tea gardens in mountainous areas

Abstract

The method for sprinkling and pumping frequency-conversion energy-saving methods for sprinkling tea gardens on slopes in mountainous areas provided by the present invention is aimed at large-scale planting of tea leaves on slopes in large areas of mountainous areas and the development of modern agricultural economy. And it can adjust the microclimate in the field to create the most suitable ecological environment for the growth of tea. Tea sprinkler irrigation can increase the air humidity, promote the growth of tea, improve the yield and quality of tea, and improve economic and social benefits. The present invention further improves and optimizes the related technology and the frequency conversion energy-saving method of mountainous slope tea garden engineering design in view of the topographic characteristics of mountainous slopes with high terrain and low water sources. The sloping sprinkler irrigation system adopts graded water lifting technology, which can not only save the investment in sprinkler irrigation of tea gardens, but also reduce the energy consumption of sprinkler irrigation and save the operating costs of tea gardens. The energy-saving effect of applying frequency converters in the sprinkler irrigation system of tea gardens in mountainous areas is also very obvious.

Description

technical field [0001] The invention relates to an energy-saving method for sprinkling irrigation graded water pumping in tea gardens, in particular to a variable frequency energy-saving method for sprinkling irrigation graded water pumping in tea gardens on mountain slopes, and belongs to the technical field of tea garden sprinkling irrigation graded water pumping. Background technique [0002] The terrain in the mountainous area fluctuates violently, the ground height difference is large, and the slope is steep, but the area is large. Through the transfer and contracting of the land, the contractors will comprehensively manage the land, plant tea on a large scale, and develop tea-specific industries. The characteristic tea garden economy can not only bring considerable benefits to the contractors, greatly increase the income of farmers, but also stimulate the enthusiasm of farmers for tea planting, and also promote the development of local tourism, improve the appearance of...

AI Technical Summary

Problems solved by technology

The sprinkler irrigation area controlled by the water pump in the prior art has a relatively high elevation, and it is impossible to avoid the problems that the sprayed water droplets are too strong due to the excessive pressure of the sprinkler head, causing damage to the tea leaves and scouring the soil on the slope, and cannot protect the vertical pipe and the sprinkler head. Pipes have a shorter service life

[0010] The third is that in the mountainous area sprinkler irrigation project of the prior art, the electromechanical pump operates at a constant speed under the power frequency power supply of 50 Hz, and the sprinkler irrigation system adopts the adjustment and control facilities of the reservoir, the pressure regulating tank, and the pressure reducing valve, which can control the pressure and flow change However, they all have great limitations. It is impossible to adjust the operating characteristics of the pump to adapt to the actual changing operating conditions of the pipe network, which will reduce the working efficiency of the pump and make the work of the pump deviate from the high-efficiency area. The operation is very uneconomical and a lot of waste Energy cannot meet the requirements of constant pressure water supply for sprinkler irrigation, which makes the investment in sprinkler irrigation of tea gardens, the energy consumption of sprinkler irrigation is high, and the operating cost of tea gardens is high

When pumping and sprinkling irrigation in mountainous areas, due to the existence of natural height difference, if the water pump has been pumping and sprinkling irrigation under power frequency, it will not only waste energy, but also affect the uniformity of sprinkling irrigation and shorten the normal service life of the project

In the tea garden sprinkler irrigation project, the existing technology of water storage tanks, pressure regulating tanks and pressure reducing valves cannot adjust the operating characteristics of the water pump to adapt to the actual changing operating conditions of the pipe network, and cannot achieve the purpose of variable speed and energy saving

There is no energy-saving design for tea garden irrigation in mountainous areas in the existing technology, the investment in pipe network and power equipment is large, the energy consumption is high, and the labor intensity and cost of operation and management personnel are high.
