[0041] See also Figure 2 , Figure 5 and Figure 6The lifting assembly 8 includes a sleeve 81 located at a corner of one side of the base box 6, a shaft 82 is fixedly connected to the center of the top of the sleeve 81, the shaft 82 is rotatably sleeved on the top of the base box 6, and a top plate 83 is fixedly connected to the top of the shaft 82, and the top plate 83 is in sliding contact with the top of the base box 6, a vertical screw 84 is extended and screwed to the inner wall of the bottom end of the sleeve 81, a bottom of the vertical screw 84 is fixedly connected to a bottom plate 85, and a universal wheel 86 is fixedly installed at the bottom of the bottom plate 85;

[0043] The driving assembly 9 includes a chain 91 that is meshed with the outer wall connection of the four interlocking gears 88, and the chain 91 is arranged in a rectangular shape inside the base box 6.

[0044] See also Figure 7 The photovoltaic energy storage system in the cabinet 1 includes a battery module and an EMS controller arranged therein, and the battery module and the EMS controller are electrically connected to each other. The battery module is also electrically connected to an external solar cell array, and the EMS controller is connected to a DC circuit breaker through a wire in one way and is electrically connected to an external DC load terminal, while the EMS controller is connected to an inverter through a wire in another way, and then connected to an AC circuit breaker, and is electrically connected to an external AC load terminal.

[0045] The implementation principle of the embodiment of the present application is as follows: when in use, the whole is in a complete assembly state, and by starting the function of the fan unit 11, the gas inside the cabinet 1 is discharged to the outside through a through slot 3 on the upper side and the heat dissipation net 4, and the inside of the cabinet 1 is simultaneously made to be in a negative pressure state, so that the gas outside the cabinet 1 enters the inside through a through slot 3 on the lower side and the heat dissipation net 4, and the air pressure balance inside the cabinet is ensured, and the heat generated by the electronic components inside the cabinet 1 when working is effectively and quickly dissipated;

[0046] During the rapid heat dissipation process inside the cabinet 1, since the heat dissipation net 4 will filter the particulate impurities contained in the gas, impurities will adhere to its outer surface. Each motor 56 can be started regularly to drive the horizontal screw 55 to rotate, while indirectly making the displacement bar 52 perform horizontal reciprocating motion inside the outer frame 51, so as to cooperate with the brush 53 to clean the impurities on the outer surface of the heat dissipation net 4, and the cleaned impurity particles will directly fall out of the inner part of the outer frame 51 through the notch groove 59 below the brush 53;

[0047] When adjusting the overall position, it is only necessary to start the motor 92 and rotate the driving gear 93. Due to the meshing state of the driving gear 93 and one of the linkage gears 88, and the meshing linkage state of each linkage gear 88 through the chain 91, the synchronous rotation of each linkage gear 88 can be realized, and the self-rotation of each sleeve 81 can be indirectly realized. Due to the screw connection between each sleeve 81 and the vertical screw 84, and the vertical movement limiting effect of each slide arm 87 and the limiting slide groove on the vertical screw 84 and the chassis 85, the downward movement of each universal wheel 86 is indirectly realized and the bottom of the base box 6 is exposed (in this process, the cabinet 1 and the base box 6 are lifted upward slightly as a whole), thereby realizing the overall position adjustment. However, when each sleeve 81 rotates passively, its top is limitedly rotated at the top position of the base box 6 through the shaft 82 and the top plate 83.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
