Automatic water storage and replenishment system for paddy field well irrigation and drying pool

Abstract

The invention discloses an automatic water storing and charging system for a paddy field well irrigation water sunning pond, and belongs to irrigation and water conservancy mechanical equipment. A water guiding and charging pipe and a water pump water inlet pipe are connected onto a water lift main pipe respectively through a three-way valve A; the water lift main pipe is communicated with a water guiding and charging tank through the water guiding and charging pipe; the water lift main pipe is communicated with a centrifugal water pump through the water pump inlet pipe; a magnetic valve is mounted on the water guiding and charging pipe; a water level sensor is mounted on the water pump inlet pipe; a water pond injection pipe and a water tank injection pipe are mounted on the water pump water outlet pipe of the centrifugal water pump through a three-way valve B; the centrifugal water pump is communicated with a water sunning pond through the water pond injection pipe, and is communicated with the water guiding and charging tank through the water tank injection pipe; a sedimentation tank is arranged at the bottom of the water sunning tank, and is communicated with a water filter tank through a communicating pipe; the water filter tank is communicated with a well through an underground water charging pipe. The system is novel and reasonable in structure, high in water charging automation degree and water resource use ratio, reliable in operation, and simple, easy and convenient to operate.

Description

technical field [0001] The invention belongs to farmland water conservancy machinery and equipment, and mainly relates to an automatic water storage and water replenishment mechanical system for a drying pond for irrigating paddy fields with groundwater (well water). Background technique [0002] In areas where groundwater is used as water for paddy fields, especially in Heilongjiang and other provinces in northern my country, due to the low temperature of groundwater, directly pouring it into paddy fields from the ground will affect the growth and development of rice. Therefore, in the groundwater irrigation system, all A sun-drying pool must be set up, that is, the groundwater is first poured into the sun-dried pool, heated by sunlight, and then poured into the rice field. In production practice, due to the decline of the groundwater level, the liquid level in the water main pipe of the centrifugal water pump is not high enough, so before using the centrifugal water pump to...

AI Technical Summary

Problems solved by technology

In production practice, due to the decline of the groundwater level, the liquid level in the water main pipe of the centrifugal water pump is not high enough, so before using the centrifugal water pump to lift water, it is necessary to manually inject water into the water main pipe to reduce the water level in the water main pipe. When the liquid level is raised to the height that the centrifugal water pump can lift water, the centrifugal water pump can be started to lift the groundwater into the drying pool, which is not only labor-intensive and wasteful of manpower, but also low labor efficiency and many operations

In addition, when the paddy field does not need water, a large amount of rainwater cannot be collected and flowed into the well to supplement the groundwater source, resulting in a large loss and waste of water resources
