[0045] Through the water delivery component, the rainwater collected in the water trough 6 can be input into the water tank 3, and the water tank 3 is used to store the rainwater. The position of the spray component can be adjusted by utilizing the functions of the spray component, the delivery component, and the connecting component, so that the spray component can not only irrigate the crops under the photovoltaic panel 23, but also flush the surface of the photovoltaic panel 23.

[0046] The water delivery component includes:

[0050] Negative pressure pipe 28, negative pressure pipe 28 is arranged on the input port of the water pump.

[0051] Furthermore, it also includes:

[0052] The pipe body 7 is provided through the bottom of the water tank 6;

[0053] The connecting seat 8 and the tube body 7 are connected by threads;

[0054] The filter screen 29 is fixed on the bottom inner wall of the connecting seat 8.

[0055] Furthermore, it also includes:

[0056] The connecting pipe 9 is connected to the connecting seat 8;

The first solenoid valve 11 is connected to the water tank 3 , the second solenoid valve 12 is connected to the connecting pipe 9 , and the three-way pipe 10 is connected to the negative pressure pipe 28 .

[0058] When it rains, rainwater is guided into the water tank 6 through the inclined photovoltaic panel 23 to collect rainwater. Then the water pump is turned on. When the water pump is working, the water in the water tank 6 is pumped into the water tank 6 through the connecting pipe 9, the first solenoid valve 11, the three-way pipe 10, and the negative pressure pipe 28, and the water is injected into the water tank 3 through the positive pressure pipe 22 and the self-operated pressure regulating valve 24.

[0067] Two output seats 19 are respectively arranged on the two side walls of the counterweight block 18, and a roller 20 is fixed at the bottom of each output seat 19.

[0068] The multi-stage electric push rod 16 is turned on. When the multi-stage electric push rod 16 is working, it drives the counterweight 18 to move through the fixed seat 17 and the rotating shaft 30, so that the counterweight 18 is away from the photovoltaic panel 23. The motor 14 is turned on to drive the fixed block 15 to rotate, thereby rotating the counterweight 18 and the two output seats 19, so that the two output seats 19 can rotate to the bottom of the photovoltaic panel 23.

[0069] Under the action of the counterweight 18, the bottom of the output seat 19 is always facing downward, and when the output seat 19 rotates to the bottom of the photovoltaic panel 23, the crops can be irrigated;

[0070] If the output seat 19 is above the photovoltaic panel 23 , the photovoltaic panel 23 can be flushed.

[0071] Furthermore, a plurality of atomizing nozzles are provided at the bottom of one of the output seats 19 , and a plurality of fan-shaped nozzles are provided at the bottom of the other output seat 19 .

[0072] Furthermore, the spray assembly also includes:

[0073] A fixing plate 31, the fixing plate 31 is fixed to one of the fixing seats 17;

[0074] The adjusting seat 32 is fixed to the fixing plate 31;

[0075] Two connecting pipes 33 are equidistantly disposed on the side wall of the adjustment seat 32 and are connected to the two output seats 19 respectively;

[0076] The seat body 34 is rotatably disposed in the adjustment seat 32, and the seat body 34 and the rotating shaft 30 are fixed;

[0077] An L-shaped hole 35 is defined in the seat body 34 .

[0078] Furthermore, it also includes:

[0079] A third solenoid valve 27 is provided on the positive pressure pipe 22;

[0080] The delivery pipe 26 has one end connected to the third solenoid valve 27 , and one end of the delivery pipe 26 is rotatably connected to the inner wall of the L-shaped hole 35 .

[0081] When the third solenoid valve 27 is turned on, in conjunction with the self-operated pressure regulating valve 24 , when the water pump is working, water can be delivered to the seat body 34 through the third solenoid valve 27 and the delivery pipe 26 .

[0082] Furthermore, a water supply pipe 25 is provided through the top of the water tank 3 .

[0083] In seasons when rainfall is insufficient, water can be promptly replenished into the water tank 3 through the water supply pipe 25 .

[0084] The specific working method is as follows: when it rains, rainwater is guided to the water tank 6 through the inclined photovoltaic panel 23 to collect rainwater. Then, the water pump is turned on. When the water pump is working, the water in the water tank 6 is pumped into the water tank 6 through the connecting pipe 9, the first solenoid valve 11, the three-way pipe 10, and the negative pressure pipe 28, and the water is injected into the water tank 3 through the positive pressure pipe 22 and the self-operated pressure regulating valve 24.

[0085] During the above process, impurities in the water are filtered out by the filter 29 to avoid accumulation of impurities in subsequent pipes or water tanks 3;

[0086] If the crops need to be watered, the switch of the multi-stage electric push rod 16 is turned on. When the multi-stage electric push rod 16 is working, it drives the counterweight block 18 to move through the fixed seat 17 and the rotating shaft 30, and the switch of the motor 14 is turned on to drive the fixed block 15 to rotate, thereby causing the counterweight block 18 and the two output seats 19 to rotate. Under the action of the counterweight block 18, the bottom of the output seat 19 is always facing downward, and then when the output seat 19 rotates to below the photovoltaic panel 23, the crops can be watered;

[0087] During the rotation of the counterweight 18, the base 34 is driven to rotate by the rotating shaft 30 so that the end of the L-shaped hole 35 faces one of the connecting pipes 33, while the other connecting pipe 33 is sealed by the base 34;

[0088] When watering is to be performed, the water pump switch and the third solenoid valve 27 switch are turned on. When the water pump is working, the water in the water tank 3 is pumped out through the first solenoid valve 11, the three-way pipe 10 and the negative pressure pipe 28, and the water is injected into the L-shaped hole 35 of the seat body 34 through the positive pressure pipe 22, the third solenoid valve 27 and the delivery pipe 26. The water then enters the corresponding output seat 19 through the corresponding connecting pipe 33 and is output from the atomizing nozzle below the output seat 19 to perform crop watering.

[0089] When the photovoltaic panel 23 needs to be cleaned, the counterweight 18 and the output seat 19 are located above the photovoltaic panel 23 through the action of the multi-stage electric push rod 16 and the fixed block 15. Then, the switch of the multi-stage electric push rod 16 is turned on, so that the output seat 19 gradually approaches the photovoltaic panel 23, and the roller 20 is in contact with the surface of the photovoltaic panel 23. Then, through the mutual cooperation of the multi-stage electric push rod 16 and the motor 14, the extension and contraction of the multi-stage electric push rod 16 can make the roller 20 always in contact with the photovoltaic panel 23. Through the action of the motor 14, the multi-stage electric push rod 16 is driven to rotate, and the output seat 19 is moved along the surface of the photovoltaic panel 23. At this time, water enters the corresponding output seat 19 through another connecting pipe 33. The water in the output seat 19 is output through the fan-shaped nozzle to achieve flushing of the photovoltaic panel 23.
