Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figure 1-11 As shown, this embodiment of the invention provides an intelligent photovoltaic high-voltage dedicated access cabinet, including a cabinet body 1. A cabinet door 2 is movably connected to the front surface of the cabinet body 1 via a side hinge. A cabinet lock 6 is provided on the other side of the cabinet door 2, and is used to limit the cabinet body 1 to its position on the front surface. A sealing gasket 3 is provided on the lower surface of the cabinet body 1, and the gaskets are internally interconnected. The interior of the sealing gasket 3 is used to connect wiring, serving a sealing function. Two airflow adjustment flipping devices 5 are provided on the inner wall of the cabinet body 1, and are arranged opposite each other. A placement rack 7 is fixedly connected to the inner bottom wall of the cabinet body 1. A water distribution block 4 is fixedly connected to the upper surface of the cabinet body 1. An air outlet assembly 8 for ventilating is provided on the inner bottom surface of the cabinet body 1. A filter assembly 9 for absorbing moisture is provided on the inner bottom surface of the cabinet body 1.

[0031] The flipping device 5 includes a flipping frame 501, a sliding groove 502, a fan 503, a sliding rod 504, a pull rope 505, a fixing block 506, a first movable wheel 507, a first torsion spring 508, a fixing rod 509, a guide plate 510, a limiting head 511, a second movable wheel 512, a fixing frame 513, a hanging basket 514, and a ventilation grille 515; the guide plate 510 is fixedly connected to the surface of the inner two side walls of the cabinet 1; the ventilation grille 515 is located on both sides of the cabinet 1 near the bottom; the limiting head 511 is fixedly connected to the upper surface of the guide plate 510; the fixing rod 509 is fixedly connected to both ends of the flipping frame 501; the first torsion spring 508 is sleeved on the outer side wall surface of the fixing rod 509; one end of the first torsion spring 508 is fixedly connected to the inner surface of the limiting head 511, and the other end is fixedly connected to the side surface of the flipping frame 501; the flipping frame 501... 1. A fixed rod 509 is movably connected to the inner surface of the limiting head 511; a fan 503 is fixedly connected to the inner support rod of the flipping frame 501; a sliding groove 502 is fixedly connected to the upper surface of the guide plate 510; a sliding rod 504 is fixedly connected to one side surface of the flipping frame 501; one end of a pull rope 505 is fixedly connected to the side surface of the sliding rod 504; a fixed block 506 is fixedly connected to the inner wall surface of the cabinet 1; a first movable wheel 507 is rotatably connected to the inner surface of the fixed block 506; the other end of the pull rope 505 passes through the surface of the first movable wheel 507, and through the side wall of the cabinet 1 and the surface of the second movable wheel 512, and is fixedly connected to the upper end of the hanging basket 514; a fixed frame 513 is fixedly connected to the outer wall surface of the cabinet 1; a second movable wheel 512 is rotatably connected to the inner wall surface of the fixed frame 513; and the lower end of the hanging basket 514 is provided with a through hole.

[0032] When the basket 514 is empty, the torque of the first torsion spring 508 is greater than the weight of the basket 514, and the basket 514 is located at a high position. When the basket 514 is filled with water, the weight of the basket 514 is greater than the torque of the first torsion spring 508, causing the basket 514 to drive the tilting frame 501 to tilt. The basket 514 has a conical structure. When there is a lot of water, the water does not flow away quickly inside the basket 514, resulting in water remaining in the basket 514.

[0033] The air outlet assembly 8 includes a vent plate 801, a fixed long rod 802, a second torsion spring 803, and a blocking block 804; two vent plates 801 are provided and are arranged opposite to each other; the fixed long rod 802 is fixedly connected to one side surface of the vent plate 801; the second torsion spring 803 is sleeved on the outer side wall of one end of the fixed long rod 802; one end of the second torsion spring 803 is fixedly connected to the inner surface of the cabinet 1, and the other end is fixedly connected to one end surface of the vent plate 801.

[0034] The ventilation plate 801 can only be flipped downwards in the cabinet 1 to release air. When it is flipped upwards, it will be blocked by the blocking block 804 and cannot be flipped.

[0035] The filter assembly 9 includes a filter screen 901 and a water-blocking material 902; the filter screen 901 is fixedly connected to the lower end of the cabinet 1; the water-blocking material 902 is installed on the upper surface of the filter screen 901; the front surface of the filter screen 901 is provided with a door for removing the water-blocking material 902.

[0036] Water-blocking material 902 is an activated carbon material used to reduce the amount of water vapor generated when a large amount of rainwater falls into the cabinet 1.

[0037] Working principle: When dissipating heat inside the cabinet 1, the fan 503 in the flip frame 501 is activated to deliver the external airflow through the channel between the guide plate 510 and the ventilation grille 515 into the interior of the cabinet 1. The airflow is then blown onto the instrument connected to the cabinet through the arc-shaped block at the upper end of the cabinet 1. The hot air then flows to the position of the air outlet component 8 inside the placement rack 7 and blows open the ventilation plate 801, carrying the hot air away from the cabinet 1.

[0038] When it rains, rainwater falls on the water distribution block 4 and is diverted into the two hanging baskets 514 on both sides. The amount of water entering the hanging basket 514 is greater than the amount of water leaking out, causing the weight of the hanging basket 514 to exceed the torque of the first torsion spring 508, thus causing it to slide down and pull the pulling rope 505. The pulling rope 505 pulls the sliding rod 504 to slide from the inner wall of the sliding groove 502, thereby causing the flipping frame 501 to flip. When the flipping frame 501 flips, the airflow inside the cabinet 1 is blown out from the outlets on both sides of the cabinet 1. The external airflow is delivered to the cabinet 1 after passing through the filter screen 901 and the water-blocking material 902 to dry the gas. At the same time, the ventilation plate 801 is blocked by the blocking block 804 and is in a closed state to prevent gas from entering.

[0039] When the rain stops, the rainwater leaks out of the basket 514. The weight of the basket 514 is less than the torque of the first torsion spring 508, thus flipping the tilting frame 501 back to its original position and moving the basket 514 back to its original position.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
