Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural irrigation equipment technical field more specifically, the utility model relates to a water treatment device for irrigation. BACKGROUND

[0002] When irrigating farmland or gardens, a water pump is usually used to suck water from a nearby source, which is then transported to a sprinkler device through a water delivery pipe for irrigating crops or flowers, trees and other plants. The water source in an outdoor environment contains impurities such as water plants and stones, so it is usually necessary to filter the water source to prevent impurities from clogging the sprinkler device and to prevent damage to the water pump and other equipment during water delivery.

[0003] To solve the above technical problems, a water treatment device for water conservancy irrigation is disclosed in the utility model patent with the publication number CN208161175U, which includes a main pipe and a filter screen and an intercepting brush arranged in the main pipe. The above-mentioned patent technology attempts to remove water plants in the water source by wrapping them with the intercepting brush and to remove stones in the water source by filtering them with the filter screen. The intercepting brush in the above-mentioned patent technology is arranged in the main water pipe, and impurities such as water plants and leaves in the water source will enter the main water pipe. On the one hand, this will clog the main water pipe and affect the pumping efficiency of the water source. On the other hand, some water plants or leaves will not be intercepted by the intercepting brush and will flow to the filter screen, which will easily clog the filter screen and further reduce the pumping efficiency of the water source. In addition, in the above-mentioned patent technology, the intercepting brush and the filter screen need to be removed from the main water pipe when the device is stopped working, so that the intercepting brush and the filter screen can be cleaned. In actual irrigation applications, the above-mentioned patent technology requires multiple stops for cleaning the intercepting brush and the filter screen in order to ensure the pumping efficiency of the water source, which greatly reduces the irrigation efficiency.
