Disclosure of Invention
The invention provides a photovoltaic energy-saving electrical control cabinet, which solves the technical problem that the heat dissipation effect is influenced because an air duct cannot be formed because heat dissipation holes on the surface of the control cabinet are arranged downwards.
In order to solve the technical problem, the photovoltaic energy-saving electrical control cabinet provided by the invention comprises a top cover, wherein a box body is fixed at the lower end of the top cover, the front end of the box body is rotatably connected with a box door, a door lock is fixed on the surface of the box door, a rotating plate is rotatably connected to the side edge of the box body, the rotating plate is rotatably connected with a ventilating plate relative to the other end of the box body, an air inlet hole is formed in the surface of the ventilating plate, an elastic plate is fixed on the outer edge of the air inlet hole, a telescopic rod is rotatably connected to the bottom of the rotating plate, a fixed seat is sleeved at the lower end of the telescopic rod, and a bottom plate is fixed at the lower end of the fixed seat.
Preferably, the lower end of the box body is provided with a threading hole, and a U-shaped rail is fixed inside the box body.
Preferably, the heat dissipation device is symmetrically arranged on the surface of the box body, and the elastic plate is made of elastic materials.
Preferably, the surface of the box body is provided with an opening, and the position of the opening corresponds to the position of the elastic plate.
Preferably, nitrogen is arranged inside the fixed seat.
Preferably, one end of the bottom plate is fixed on the surface of the box body.
Preferably, the upper end of the top cover is provided with an inclined surface, and the bottom area of the top cover is larger than the top area of the box body.
Compared with the related art, the photovoltaic energy-saving electric control cabinet provided by the invention has the following beneficial effects:
according to the invention, the height of the ventilating plate is automatically adjusted through the expansion and contraction of nitrogen in the fixing seat, and the angle of the elastic plate is controlled, so that the air inflow is controlled, when the temperature in the midday box body is high, the air volume of parallel air can be increased, a stable air duct is formed in the box body, the heat dissipation speed is accelerated, meanwhile, the elastic plate is inclined downwards at night, the entry of cold air is reduced, dew formation in the morning is avoided, and the safety of equipment in the control cabinet is protected.
