Description

Cabinet top structure of electric cabinet Technical Field The application relates to the field of electrical cabinet structures, in particular to a cabinet top structure of an electrical cabinet. Background The cabinet top structure of the existing electrical cabinet comprises a shell and a fan, wherein the shell is arranged at the top of the electrical cabinet, the fan is arranged on the shell, the fan is used for exhausting air upwards, so that hot air in the electrical cabinet is pumped into the shell, and then the hot air is discharged through vent holes around the shell. According to the application environment of the electrical cabinet, the cabinet top structure is different, for example, the indoor electrical cabinet has no rainproof and sand-proof requirements, the ventilation hole of the shell can be arranged to be larger, and meanwhile, a filter screen is not needed or a protective screen with larger holes is adopted. If outdoor regulator cubicle often need set up the less filter screen in hole to and set up the eaves of keeping off the rain in the casing top, with the splash that reduces the side direction rainwater, but because the hole of filter screen is less, the air output of fan is less, will lead to the fan to heat extraction resistance great, the radiating effect is poor, especially under the great environment of sand-blown, the sand-blown is easy to pour into in the ventilation hole into, consequently, still need add the filter pulp when setting up the filter screen, with isolated sand, but will further increase the heat extraction resistance of fan like this, the radiating effect is worse. Disclosure of Invention In order to achieve the effects of rain prevention, sand prevention and heat dissipation, the application provides a cabinet top structure of an electric cabinet. The application provides a cabinet top structure of an electrical cabinet, which adopts the following technical scheme: the top plate and the bottom plate are respectively sealed and fixed on an upper port and a lower port of the middle shell, the fan assembly is arranged on the bottom plate and used for conveying hot air into the middle shell from bottom to top, the four on-off structures are respectively arranged on four side walls of the middle shell and are respectively in an air outlet state and an off state, the upper sides of the four baffles are respectively hinged with four side edges of the top plate, the baffles are in a first inclined state and a second inclined state, when the baffles are in the first inclined state, the lower sides of the baffles are obliquely arranged in a direction away from the middle shell, the on-off structures are in the air outlet state, acting force of the on-off structures in the air outlet state is applied to the baffles through the linkage structures so that the baffles maintain the first inclined state, and in the process of converting the baffle from the first inclined state to the second inclined state, the baffle swings along the direction towards the middle shell, and the displacement acting force of the baffle is applied to the on-off structure through the linkage structures so that the on-off structure is converted from the air outlet state to the off state. Through adopting above-mentioned technical scheme, under the less circumstances of no wind or wind, the break-make structure is in the air-out state, and the effort of the break-make structure of air-out state is applied to the baffle through the linkage structure to make the baffle maintain first slope state, at this moment, the steam in the mesochite can be discharged through the break-make structure of air-out state, in order to improve the radiating effect, and, the baffle of first slope state is kept away from the mesochite, can effectively reduce the baffle to the hindrance of hot-blast discharge, thereby reduce the heat extraction resistance. Under the condition that the wind sand is large, one or two baffles in the corresponding direction can be blown by a certain lateral large wind force, the corresponding baffles deflect towards the middle shell direction, the baffles are enabled to be changed into a second inclined state from a first inclined state, in the process, the displacement acting force of the baffles is applied to the on-off structure through the linkage structure, so that the on-off structure is changed into a separation state from an air outlet state, the middle shell is isolated from the part corresponding to the on-off structure, the wind sand is separated, the baffles at other positions of the middle shell have no wind force, the baffles are still in the first inclined state, the corresponding on-off structure is still in the air outlet state, and heat dissipation under the condition of large wind sand is considered. Secondly, the baffle of first slope state can guide the rainwater slope and flow down, makes the rainwater keep away from the mesochite, and the baffle of second slope state has
