[0025] Two groups of ventilation openings 6 are provided, and the inner cavity of the ventilation openings 6 is provided with dustproof nets. The dustproof nets are provided to prevent dust in the air from entering the interior of the cabinet 1 through the ventilation openings 6 .

[0026] The air supply assembly 5 includes an air blower 51, which is fixedly connected to the top of the cabinet 1 through a mounting plate. The air inlet of the air blower 51 is connected to an air inlet pipe 52, and the other end of the air inlet pipe 52 is fixedly connected to a dust cover 53. The air supply port of the air blower 51 is connected to an air supply pipe 54, and the other end of the air supply pipe 54 penetrates the cabinet 1 and is fixedly connected to a guide cover 55. The guide cover 55 is located in the inner cavity of the cabinet 1. Starting the air blower 51 provides a driving force to inhale air through the air inlet pipe. While the air inlet pipe inhales air, it filters dust in the air through the dust cover 53. Then the air supply pipe sends the air into the interior of the cabinet 1 through the guide cover 55, thereby accelerating the flow rate of the air inside the cabinet 1.

[0027] A notch is provided on the surface of the cabinet door 7 , and a transparent glass plate 12 is embedded in the inner cavity of the notch. The transparent glass plate 12 allows the staff to observe the working status inside the cabinet 1 .

[0028] A humidity display 13 is installed on the outer surface of the cabinet door 7. The humidity display 13 is electrically connected to the humidity sensor 9. The setting of the humidity display 13 facilitates the staff to observe the humidity inside the photovoltaic energy storage control cabinet.

[0029] The fixing assembly 11 includes a stepper motor 111, which is fixedly installed in the inner cavity of the base 2. The output shaft of the stepper motor 111 is connected to a first bevel gear 112 through a key, and the surface of the first bevel gear 112 is connected to a second bevel gear 113 through meshing. A threaded rod 114 is inserted and fixed at the center of the second bevel gear 113. Both ends of the threaded rod 114 are rotatably connected to the inner cavity of the base 2 through bearings. The outer surface of the threaded rod 114 is connected to a lifting seat 115 through a thread, and the bottom end of the lifting seat 115 is fixedly connected to the support The support column 116 has a through hole at a position corresponding to the bottom end of the support column 116 and the inner surface of the base 2. The surface of the support column 116 is inserted and slid with the inner cavity of the through hole of the base 2. The stepper motor 111 is started to provide a driving force to drive the first bevel gear 112 to rotate. The surface of the first bevel gear 112 drives the second bevel gear 113 to rotate through a meshing connection. The rotation of the second bevel gear 113 drives the threaded rod 114 to rotate. The threaded rod 114 drives the lifting seat 115 to move through a meshing connection, so that the lifting seat 115 drives the support column 116 to move.

[0030] The surface of the lifting seat 115 is provided with through holes, and the inner cavities of the through holes of the lifting seat 115 are all inserted and slidably connected with sliding rods 14. There are three groups of sliding rods 14, and the positions of the three groups of sliding rods 14 are arranged in a triangular shape. Through the arrangement of the sliding rods 14, the threaded rod 114 is prevented from driving the lifting seat 115 to rotate, so that the lifting seat 115 can only move up and down.

[0031] The inner cavity of the base 2 is fixedly connected with a limit plate 15, and the limit plate 15 is located between the second bevel gear 113 and the lifting seat 115. Two groups of limit plates 1 are provided, and the two groups of limit plates 15 are fixedly connected to the inner wall of the base 2.

[0032] In specific use, when dissipating heat, the blower 51 is started to provide driving force to inhale air through the air intake pipe. While the air intake pipe inhales air, dust in the air is filtered through the dust cover 53. Then the air supply pipe sends the air into the cabinet 1 through the guide cover 55. The air takes the heat inside the cabinet 1 out from the vent 6 to achieve heat dissipation inside the photovoltaic energy storage cabinet.

[0033] During dehumidification, the humidity sensor 9 senses the humidity inside the cabinet 1 and displays it on the humidity display 13 through electrical connection. When the staff observes that the humidity rises, the humidity display 13 is activated to send a signal to the humidity sensor 9 through electrical connection. The humidity sensor 9 activates the heating element 8 through electrical connection to heat the internal air, so that the air is converted into hot air flow and flows rapidly inside the cabinet 1, and finally discharged through the vent 6, thereby dehumidifying the inside of the photovoltaic energy storage control cabinet to avoid the phenomenon of short circuit of the photovoltaic energy storage control cabinet when working in a humid environment;

[0034] When moving, start the stepper motor 111 to provide driving force to drive the first bevel gear 112 to rotate. The surface of the first bevel gear 112 drives the second bevel gear 113 to rotate through the meshing connection. The rotation of the second bevel gear 113 drives the threaded rod 114 to rotate. The threaded rod 114 drives the lifting seat 115 to move through the meshing connection. The setting of the sliding rod 14 prevents the threaded rod 114 from driving the lifting seat 115 to rotate, so that the lifting seat 115 can only move up and down. When the lifting seat 115 drives the supporting column 116 to contact the ground, the position of the photovoltaic energy storage control cabinet on the ground is fixed. When the supporting column 116 cancels the contact with the ground, it can be moved by the guide wheel 10, so that the photovoltaic energy storage control cabinet can switch back and forth between moving and fixing, and the position of the photovoltaic energy storage control cabinet can be adjusted, which is convenient for the staff to move the photovoltaic energy storage control cabinet.
