A cleaning motor 45 is provided on the cleaning slide 44. A cleaning part 46 is provided on the output shaft of the cleaning motor 45. A covering cylinder 38 is provided at one end of the photovoltaic base 4. A covering box 39 is provided on the telescopic rod of the covering cylinder 38 for covering the cleaning mounting base 41.

[0035] The principle of this invention is as follows: Photovoltaic panels 12 are arranged in an array on the photovoltaic mounting frame 11. The angle motor 27 operates, which can rotate the shaft 30 to adjust the angle of the photovoltaic panels 12, i.e., adjust the angle according to the light intensity. The telescopic rod of the fixed electric cylinder 47 can cooperate with the fixing hole on the fixed plate 48 to fix the shaft 30. Since it is generally operated outdoors, dust particles are easily accumulated on the photovoltaic panels 12. This embodiment can perform dust removal and cleaning operations in different ways. Specifically, the electric cylinder 32 can be pushed to push the slide 33, i.e., the slide 33 moves back and forth, i.e., the photovoltaic mounting frame 11 moves back and forth, which can vibrate and shake off the dust particles. Furthermore, when the slide 33 slides, the piston push plate 36 slides in the piston cylinder 35, and the resulting airflow is transmitted from the transmission pipe 37 to the airflow box 31, and finally released through the airflow box 31, which can blow away the dust particles accumulated on the photovoltaic panels 12.

[0036] The above cleaning operations are routine short-cycle cleaning processes. After long-cycle operations, if there are difficult-to-remove impurities or particles accumulated on the photovoltaic panel 12, the rotating shaft 30 can be rotated so that the photovoltaic panel 12 faces the photovoltaic base 4. The operation is carried out by the moving belt 10, the cleaning control cylinder 40 moves, the cleaning control cylinder 40 controls the lifting and lowering of the cleaning mounting base 41, the cleaning motor 45 works, the cleaning unit 46 performs the cleaning operation, the motor 3 42 works, and the lead screw 3 43 rotates to adjust the position of the cleaning slide 44. Furthermore, when the cleaning unit 46 is not working, at one end of the moving belt 10, the covering cylinder 38 controls the covering box 39 to cover the cleaning mounting base 41 to provide a shielding and protective function.

[0037] For energy storage operations, electrical energy is stored through battery modules 9. Airflow is transmitted through cooling fans 3, bringing external air into the energy storage box 1. The airflow is filtered by filter box 5 and then passes through air inlet box 6, heat dissipation pipe 7, and air outlet box 8 to achieve air circulation, thereby removing heat from the energy storage box 1 and cooling the battery modules 9. Furthermore, motor 16 operates, and position belt 15 moves the fixed seat 20. Motor 29 operates, and lead screw 28 rotates to adjust the position of moving seat 21. Control cylinder 22 controls the lifting and lowering of detection box 23, allowing each battery module 9 to be moved above it for localized testing. Temperature detector 24 detects the temperature of each battery module 9. For battery modules 9 with temperatures higher than normal, auxiliary cooling is provided. Coolant is circulated through two cooling circulation boxes 17 and circulates around the outside of the battery modules 9 through cooling circulation pipes 25 to remove heat and provide auxiliary cooling.

[0038] Furthermore, for dehumidification inside the energy storage box 1, desiccant 60 can be placed in the limiting frame 59 and transported to the inside of the energy storage box 1 by the dehumidification conveyor belt 56 for dehumidification. The placement base 58 and the magnetic transport seat 57 are magnetically fixed for easy placement and removal. After a certain period of use, the dehumidification conveyor belt 56 will transfer the limiting frame 59 to the slot on the side of the energy storage box 1 one by one. Then, the transfer control cylinder 53 controls the movement of the transfer frame 49, and the transfer motor 50 controls the movement of the transfer belt 51. The magnetic fixing seat 52 cooperates with the magnetic hole on the top of the limiting frame 59 to transfer the placement base 58 away from the placement base 58. In the drying box 2, the used desiccant 60 can be dried and then transferred back to the energy storage box 1. During the transfer, the baffle cylinder 54 controls the movement of the baffle 55 to control the sealing state of the side of the energy storage box 1.
