AI Technical Summary
When used in the existing rainwater collection wells for farmland water conservancy circulation drainage and irrigation equipment, most of them are used to collect rainwater through a single collection port. When the amount of rainwater is small, it cannot meet the rainwater collection needs of the water collection well, and it is easy to cause the water storage well to flood, and the garbage drifting in the rainwater is likely to enter the water collection well, causing the garbage to enter the outlet pipe during water use, causing the pipeline to be blocked or the pump body to be damaged.
A farmland water conservancy circulation drainage device was designed. Four collection pools were installed on the four sides of the reservoir well to collect rainwater. The rainwater entered the reservoir through the inlet tank in the protective plate and was discharged into the reservoir through the drain pipe, trough and water inlet pipe. At the same time, a flow blocking device is used to prevent rainwater from flowing into the reservoir, avoid flooding, and filter garbage in the rainwater through the filter net in the collecting pool.
The four water collection pools improve the rainwater collection efficiency, solve the problem that small rainfall can meet the rainwater collection needs of water storage wells, prevent rainwater from flooding, and effectively filter the garbage in the rainwater, avoiding pipeline blockage and pump body damage.

[0002] Farmland water conservancy and irrigation and drainage devices are water conservancy engineering measures aimed at increasing agricultural production. That is, through the construction and use of various water conservancy engineering measures, the moisture conditions of farmland and regional water conservancy conditions are regulated and improved, the ability to resist natural disasters is improved, and the virtuous cycle of the ecological environment is promoted to make it conducive to the production of crops. In order to better save water, water storage wells are generally set up on the edge of the farmland to collect rainwater, and the collected rainwater is used to irrigate the farmland.
[0003] However, when the existing rainwater collection wells for agricultural water conservancy circulation irrigation and drainage devices are in use, most of them collect rainwater through a single collection port. When the amount of rainwater is small, it cannot meet the collection needs of the collection well for rainwater. Moreover, after the water storage in the water storage well is completed, the rainwater entering the collection port continues to flow into the water storage well, which is easy to cause the water storage well to overflow. When observing the water storage amount or usage in the water storage well, most of the time, the sealing cover on the top of the water collection well is directly opened to observe the water collection well, which is less safe. Secondly, when rainwater enters the water collection well through the collection port, garbage floating in the rainwater is easy to enter the water collection well, which is inconvenient to clean and it is easy to cause garbage to enter the outlet pipe when using water, causing pipe blockage or pump damage.
