Abstract

The invention discloses a photovoltaic grid-connected cabinet with a state monitoring function, which is applied to the technical field of electrical cabinets, and the invention applies force to an elastic wind direction sailboard by strong wind under the strong wind environment to lead an exhaust pipe to rotate, so as to realize that the V-shaped tip of the elastic wind direction sailboard always faces the strong wind direction, the elastic wind direction sailboard prevents the strong wind from directly blowing to an air outlet area at the outer end of the exhaust pipe, effectively prevents sundries carried by the strong wind from blocking the exhaust pipe, and effectively prevent strong wind from blowing in the exhaust pipe with the dust, realize that strong wind blows in the aspiration channel voluntarily through the air intake to the both ends of elastic wind direction windsurfing board receive the wind-force influence of strong wind and draw close each other, make two gangbars close and exert the impulse force to the push-and-pull rod, push-and-pull rod promotes the deep bead and closes the motion to the air intake, reaches the effect that the wind-force of strong wind is bigger, and the deep bead is higher to the degree of closing of air intake, effectively controls the intake of aspiration channel.
