Abstract

The invention discloses a vent hole protecting device for an outdoor box, which comprises a shell; the shell comprises a bridging board, two lateral boards which are located at two sides of the bridging board and are connected through the bridging board, and end boards for closing the back ends of the two lateral boards and the bridging board. The vent hole protecting device for the outdoor box is characterized in that: the bridging board is rectangular; a shell seat is buckled at the front end of the shell; the shell seat is provided with a communicating hole communicated with the vent hole; a downward ventilating channel is formed by the communicating hole and a cavity between the shell and the shell seat; and a dustproof net for closing the communicating hole is arranged on the shell seat. The shell seat is arranged between the shell and the outer wall of the box in the vent hole protecting device for outdoor box, so the fixing structure is firmer; meanwhile, the dustproof net is fixedly arranged on the shell seat, so the installation of the dustproof net is also firmer, thereby prolonging the life service of the vent hole protecting device; and, the cavity is formed between the shell seat and the shell, and the bridging board is rectangular, so the ventilating area is enlarged and good ventilating effect is achieved.

Description

technical field [0001] The invention relates to a ventilation hole protection device for an outdoor box, in particular to a protection device at the ventilation hole of an electrical system box such as a control cabinet, a distribution box, and a mechanism box. Background technique [0002] When the electrical system box is in use, if there is no requirement for forced ventilation, ventilation holes are generally used for heat dissipation and ventilation. There will be rainwater entering the box from the ventilation holes, which will bring safety hazards to the reliable operation of the equipment in the box. Therefore, the ventilation holes are the key protection objects. The national standard stipulates that the protection level of the above-mentioned boxes must reach IP54, so the protection of the ventilation holes The protection level of the device also needs to meet the national standard of IP54. [0003] At present, the usual method for dust prevention in the industry ...
