Description

Technical Field

[0001] The utility model relates to the technical field of farmland water conservancy, in particular to a water diversion and drainage device for farmland water conservancy foundation. Background Art

[0002] Farmland water conservancy is a water conservancy engineering measure, which mainly develops irrigation and drainage, regulates regional water conditions, improves the moisture conditions of farmland, prevents drought, waterlogging, salt and alkali disasters, and promotes a comprehensive science and technology of stable and high agricultural production. Farmland water conservancy is generally called irrigation and drainage abroad. Its task is to intercept, regulate, distribute and use agricultural water resources through engineering and technical measures, and to improve soil and fertilize the land in combination with agricultural technical measures to expand land use in order to achieve the goal of high and stable agricultural production. The development of farmland water conservancy is inseparable from the diversion and drainage of farmland. The most common diversion and drainage in rural areas is mainly to use water pumps to pump water. Since most of the water sources for agricultural water use are from surrounding ponds and rivers, these water sources contain a lot of impurities. In the process of using long-term water pumps for diversion and drainage, impurities pass through the inside of the water pump, and some impurities will be adsorbed on the inner wall of the water pump, which will cause damage to the water pump over time.

[0003] After searching, a Chinese patent discloses a water diversion and drainage device for farmland water conservancy foundation (authorization announcement number CN214577689U), including a vertical water pump, the vertical water pump is fixedly provided with a connecting square tube, a sliding frame is arranged inside the connecting square tube, a filter plate is fixedly arranged inside the sliding frame, the filter plate is fixedly provided with a waterproof cover, a motor is fixedly arranged inside the waterproof cover, a power output shaft of the motor passes through the filter plate and is fixedly connected to a scraper, the waterproof cover is connected to a cross-shaped mounting frame through a spring on one side close to the vertical water pump, the cross-shaped mounting frame is fixedly connected to the connecting square tube, a self-resetting push switch is arranged inside the spring, the self-resetting push switch is fixedly connected to the cross-shaped mounting frame, and a rotating mechanism is fixedly arranged at the bottom of the vertical water pump. Although the patented technology can filter impurities in the water through the filter plate to prevent impurities from entering the water pump and causing internal damage to the water pump, it can also separate impurities adsorbed on the filter plate from the filter plate, prevent the filter plate from being blocked, and greatly improve the utilization rate of the filter plate.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that in the above-mentioned water diversion and drainage device for farmland water conservancy foundation, impurities in the water are filtered through a filter plate to prevent impurities from entering the water pump and causing internal damage to the water pump. The filter plate is driven to operate by a motor fixedly installed in the connecting square pipe. This installation method is not convenient for the staff to inspect and repair the motor in time, resulting in the filter plate surface still being clogged by impurities after the motor is damaged, which in turn affects the pumping efficiency of the vertical water pump.
