Cleanable rainproof dustproof heat dissipation ventilation hood
Technical Field
The utility model belongs to the technical field of ventilation hood equipment, and particularly relates to a cleanable rainproof dustproof heat-dissipation ventilation hood.
Background
In power equipment with high protection level requirements such as outdoor power distribution cabinets, box transformer, prefabricated cabins and the like, natural ventilation or forced air exhaust of fans is usually required to be conducted on equipment through an air window, and then the electrical equipment in the cabinet can be effectively cooled and operated. It is common in the market to use a shutter with a high protection level to be installed at the air inlet and outlet of the cabinet (box), and the shutter contains gauze and filter cotton material to prevent dust from entering the cabinet. When the shutter is installed at the lower part of the equipment, water and dust splashed on the ground are easy to splash in from the lower part of each shutter, the dustproof net and the filter cotton are installed inside and can be taken down and cleaned and replaced from the inside only by entering the equipment, whether the dustproof net and the filter cotton are blocked or not can not be observed from the outside, and when the dustproof net and the filter cotton are replaced inside, the dustproof net and the filter cotton can be contacted with the electrified equipment, so that electric shock hazard is easily caused.
Disclosure of utility model
The utility model aims to solve the problems and provide the cleanable rainproof dustproof heat-dissipation ventilation hood which is convenient for a user to observe, clean and replace a dustproof net and dustproof cotton under the condition of meeting the protection level and ventilation heat-dissipation requirements of running equipment in the outdoor or severe environment.
In order to solve the technical problems, the technical scheme is that the cleanable rainproof dustproof heat-dissipation ventilation hood comprises a shell, wherein a U-shaped groove is formed in the bottom of the shell, a drawer structural member is arranged in the U-shaped groove, the drawer structural member comprises a drawer body, and a gauze and filter cotton are arranged in the drawer body and used for preventing dust.
Preferably, the shell is of a sheet metal part bending structure, and the section of the shell is of a trapezoid shape.
Preferably, the U-shaped groove is formed by folding the bottom of the housing.
Preferably, the drawer body is of a cuboid structure, and the lower part of the drawer body is of a hollowed-out structure.
Preferably, the gauze adopts a stainless steel filter screen, and is a net structure with the aperture not more than 2.5mm and woven or welded by 304 stainless steel wires.
Preferably, the filter cotton is an air filter cotton of synthetic fiber material.
The beneficial effects of the utility model are as follows:
1. The cleanable rainproof dustproof heat-dissipation ventilation hood provided by the utility model can be suitable for ventilation and heat dissipation of equipment in places needing outdoor rainproof, waterproof, dustproof and the like in severe environments, and can automatically select the specifications of a dustproof net and filter cotton to meet the requirements of different protection grades. For example, the device can be applied to normal heat dissipation and ventilation of air inlets and outlets of equipment such as power box transformers, power prefabricated cabins and outdoor power distribution cabinets (boxes), can prevent rainwater and dust from invading the equipment, and can maintain good heat dissipation efficiency of the equipment.
2. The dustproof net and the dustproof filter cotton of the ventilation hood are of a drawer type plug structure arranged outside equipment, so that equipment maintenance personnel can conveniently and clearly observe dust blocking conditions of the dustproof net and the dustproof filter cotton, and the dustproof net and the dustproof filter cotton of the drawer structure can be easily detached in a plug mode to be cleaned and replaced without affecting the use of the equipment.
