TECHNICAL FIELD
[0001] The utility model belongs to submersible pump technical field, concretely relates to a submersible pump for farmland irrigation. BACKGROUND
[0002] A submersible pump is a pump device that integrates a motor and a pump body and can work directly in water. It is widely used in agricultural irrigation, industrial water supply, urban drainage, sewage treatment, and other fields, and is particularly suitable for pumping liquid from underground wells, rivers, lakes, and other water sources. The core components of a submersible pump include a sealed motor and a pump body connected thereto. The motor drives the impeller inside the pump to rotate, and water is sucked in and discharged through the outlet by centrifugal force.
[0003] Currently, submersible pumps for farmland irrigation on the market mainly work by placing the pump body in an irrigation channel, but the existing technology still has many shortcomings. For example, the existing patent number CN219888369U, named "Irrigation Submersible Pump Debris Removal Device", includes a submersible pump body, an external hanger, and a debris removal assembly. This technology fixes the submersible pump by setting up an external hanger, making it more stable in open water. At the same time, the variable-diameter debris removal assembly allows the scraping shovel to fit the annular water suction port for impurity cleaning, thereby reducing the problem of submersible pump blockage. However, this technical solution still has limitations, i.e., although it can block impurities from entering the pump body, when the debris removal component surface is covered with a large amount of impurities, there is a lack of effective cleaning device, which affects the water flow rate and reduces the irrigation efficiency of the submersible pump. In addition, the cleaning of the debris removal component usually needs to be done manually, increasing the complexity and time cost of maintenance.
[0004] On the other hand, during the process of farmland irrigation, the water level of the irrigation channel will change with the season or usage frequency, and the existing submersible pump usually cannot be flexibly adjusted according to the water level change. This fixed installation method not only makes it difficult to efficiently pump water at low water levels, but also easily leads to unstable operation of the equipment, affecting the continuity and efficiency of irrigation operations.
