Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0013] Embodiment 1, in combination with Figure 1A winter-summer dual-purpose photovoltaic panel cleaning device comprises a water pool 1, an air compressor room 2, and a main pipeline 3. The water pool 1 is provided with a plurality of water pumps and motors 4. The air compressor room 2 is provided with a plurality of air compressors 5. The plurality of water pumps and motors 4 are connected in parallel to the main pipeline 3. The plurality of air compressors 5 are connected in parallel to the main pipeline 3. The main pipeline 3 is connected with a liquid ejection device 6 and a gas ejection device 7. Both the liquid ejection device 6 and the gas ejection device 7 are provided with a plurality of telescopic nozzles 8. A manual / electric / pneumatic valve 9 for isolation is provided on the parallel pipeline of the water pump and the motor 4. A manual / electric / pneumatic valve 2 10 for isolation is provided on the parallel pipeline of the air compressor 5. An overflow valve 11 is provided on the main pipeline 3. An overflow valve 2 12 is provided on the liquid ejection device 6. A pressure safety valve 13 is provided on the gas ejection device 7. During the specific implementation, it is installed synchronously with the construction of the power station. In winter, the water pump and motor 4 do not work, the partition manual / electric / pneumatic valve 1 9 is closed, the air compressor 5 works, the partition manual / electric / pneumatic valve 2 10 is opened, the gas ejection device 7 works, and compressed air is used to blow away the dust and snow on the photovoltaic panels; similarly, high-pressure flushing water is used to clean the photovoltaic panels in summer. The two methods can be freely switched by starting and stopping the equipment and switching the valves, which is convenient and fast. In addition, the device can also use independent control logic to achieve the purpose of automatic control.

[0014] The branch pipeline between the water pump and the motor 4 is provided with a manual / electric / pneumatic valve 14 for isolation, which can close / open the branch pipeline. The parallel pipeline between the water pump and the motor 4 is provided with a flow meter 15 and a pressure gauge 16, which can perform flow detection and pressure detection at this location.

[0019] The air compressor 5 is a screw air compressor.

[0020] The telescopic nozzle 8 is a non-powered telescopic nozzle with a simple mechanical limiter, which uses water pressure and compressed air pressure to achieve telescopic movement. Therefore, the telescopic nozzle 8 uses water pressure or compressed air pressure to reach the working surface during operation, and when the cleaning operation is completed, the telescopic nozzle 8 also retracts below the working surface due to loss of power, thereby avoiding potential safety hazards caused by the shadows cast by the telescopic nozzle 8 and the attached pipes due to the light angle on the operation of the photovoltaic panel.

In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0022] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0024] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto.
