Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly relates to a photovoltaic water pumping system. Background Art

[0002] The water pumping device pumps water through a water pump and applies pressure to convert electrical energy into the kinetic energy of water flow, and is commonly used in fields such as agricultural irrigation, desert control irrigation, water conservancy drought resistance water lifting, and grassland animal husbandry infiltration irrigation. Currently, when the water pumping device relying on photovoltaic power generation is used for farmland irrigation, sometimes due to the differences in the terrain of farmlands in different regions, the working position of the water pumping device is restricted, resulting in the water flow from the water delivery pipe on the water pumping device not being convenient to directly pour into the farmland. It is often necessary to temporarily install another water pipe to introduce the water flow into the farmland, which is inconvenient to operate. Moreover, during long-term use, if the water outlet of the water pipe deviates from the farmland, it will cause waste of water resources. Summary of the Invention

Then, the adjusting bolt is adjusted so that the adjusting bolt pushes the friction pressing piece until the friction pressing piece presses the positioning pressing plate against the first fixing block, thereby keeping the water pipe mounting plate fixed; after the irrigation work is completed, the cross plate is pulled upward so that the guide rod moves along the second positioning groove, and the return spring contracts until the positioning boss on one side of the cross plate disengages from the first positioning groove. Then, by rotating the rotating handle, the support column rotates along with the rotating disc. At the same time, the fixed cylinder rotates and winds the water inlet pipe around the spiral pipe groove on the outer wall of the fixed cylinder. After the cross plate is released, under the action of the return spring, the guide rod moves downward along the second positioning groove until the positioning boss on one side of the cross plate is arranged in the first positioning groove, so as to keep the fixed cylinder from moving randomly.
