[0003] After searching, the existing patent (publication number: CN208387480U) discloses a photovoltaic irrigation device that is easy to adjust. During use, the photovoltaic irrigation device that is easy to adjust not only increases the structure but also greatly improves the performance of the entire device. The internal structural design is relatively compact, which ensures the overall stability of the device and reduces damage to the solar panels. The supporting structure below can achieve angle adjustment, which is quick and convenient to use. The bottom bracket of the hollow tripod structure has better stability and can minimize the vibration of the overall structure. The load-bearing base can make the center of gravity of the water pump more stable during use without offset, and the load-bearing base is also convenient and quick to disassemble and replace. The filter suction head can filter larger impurities in the water while performing the water suction operation to ensure the quality of the water source and the normal operation of the water pump. The movable frame can be rotated and adjusted through the shaft rod to make the activity range of the entire device larger, thereby indirectly improving the scope of application of the device. However, in the process of realizing the present utility model, the inventor discovered that the prior art has the following problems: the above-mentioned photovoltaic irrigation device, when used to adjust the angle of the photovoltaic panel, adopts a method of fixing the movable frame with a fixing nut. When adjusting, it is necessary to use an external wrench to loosen the fixing nut, and then tighten it after adjustment. It has the defect of cumbersome operation, and it is difficult to meet the purpose of rapid adjustment of the inclination angle of the photovoltaic panel. In addition, during the time of using the pump body for transportation, the direct angle of the sun will be deviated.

When it is necessary to adjust the angle of the entire photovoltaic panel according to the position of the sun, the entire device needs to be moved, and the operation is cumbersome. In view of this, the present utility model proposes a photovoltaic irrigation device that is easy to adjust. Utility Model Content
