Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation hood equipment, and in particular relates to a cleanable, rainproof, dustproof and heat-dissipating ventilation hood. Background Art

[0002] In outdoor power distribution cabinets, transformer substations, prefabricated cabins, and other electrical equipment with high protection requirements, it is often necessary to open ventilation windows for natural ventilation or use fans for forced exhaust to effectively dissipate heat and maintain operation of the electrical equipment inside. High-protection shutters are commonly used on the market, installed at the air inlet and outlet of the cabinet (box). The shutters contain mesh and filter materials to prevent dust from entering the cabinet. When this type of shutter is installed at the bottom of the equipment, water and dust splashed from the ground can easily splash in from the bottom of each shutter. Furthermore, the dust screen and filter cotton are installed inside, requiring entry into the equipment to remove, clean, and replace them. Clogged dust screens and filter cotton cannot be observed from the outside, and replacing them internally can come into contact with live equipment, posing a risk of electric shock. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems and provide a cleanable rainproof and dustproof heat dissipation ventilation cover that meets the protection level and ventilation and heat dissipation requirements of equipment operating outdoors or in harsh environments, and is convenient for users to observe, clean and replace the dust net and dust cotton.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a cleanable rainproof, dustproof, heat dissipating and ventilation hood, comprising a shell, a U-shaped groove is provided at the bottom of the shell, a drawer structure is provided in the U-shaped groove, the drawer structure comprises a drawer body, and a gauze and filter cotton are installed in the drawer body, and the gauze and filter cotton are used for dust prevention.

[0005] Preferably, the shell is a sheet metal bending structure, and the cross section of the shell is trapezoidal.

[0006] Preferably, the U-shaped groove is formed by folding the bottom of the shell.

[0007] Preferably, the drawer body is a rectangular parallelepiped structure, and the lower part of the drawer body is a hollow structure.

[0008] Preferably, the gauze is a stainless steel filter mesh, which is woven or welded from 304 stainless steel wire into a mesh structure with a pore size not greater than 2.5 mm.

[0009] Preferably, the filter cotton is an air filter cotton made of synthetic fiber material.

[0010] The beneficial effects of the utility model are:

[0011] 1. This utility model provides a cleanable, rainproof, and dustproof heat dissipation ventilation cover suitable for ventilation and heat dissipation of equipment requiring outdoor protection from rain and water, as well as harsh environments. The dust screen and filter cotton specifications can be customized to meet different protection level requirements. For example, it can be used for normal heat dissipation and ventilation of the air inlets and outlets of equipment such as power transformers, prefabricated power cabins, and outdoor distribution cabinets. It can prevent rain and dust from intruding into the equipment while maintaining good heat dissipation efficiency.

[0012] 2. The dust screen and dust filter cotton of the ventilation hood of the utility model are a drawer-type plug-in structure installed outside the equipment, which can facilitate equipment maintenance personnel to clearly observe the dust blockage of the dust screen and dust filter cotton. The dust screen and dust filter cotton of the drawer structure can be easily removed by plugging and unplugging for cleaning and replacement without affecting the use of the equipment at all.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 8As shown, the utility model provides a cleanable, rainproof, dustproof, heat dissipating and ventilation hood, including a shell 1, a U-shaped groove 2 is provided at the bottom of the shell 1, a drawer structure 3 is provided in the U-shaped groove 2, the drawer structure 3 includes a drawer body 5, and a gauze 6 and filter cotton 7 are installed in the drawer body 5, and the gauze 6 and filter cotton 7 are used for dust prevention.

[0024] The housing 1 is a sheet metal bending structure, and the cross section of the housing 1 is trapezoidal. The bottom length of the trapezoidal structure is set according to the required size, and the height of the trapezoidal structure is 200 mm.

[0025] In this embodiment, the housing 1 is provided with mounting holes 4. These holes are through-holes and are distributed along the edge of the housing 1. They are used to connect to external devices. There are twelve mounting holes 4, with each group of three holes 4 located on the same side of the housing 1.

[0026] After the ventilation hood of the present invention is manufactured, when the ventilation hood is mounted on the housing of an existing device, bolts are installed on the housing of the existing device, and the bolts are passed through the mounting holes 4 and then fitted with corresponding nuts to achieve the installation of the ventilation hood of the present invention. In actual use, the size and position of the mounting holes 4 can be set according to the actual position and size of the bolts to increase its practicality.

[0027] The U-shaped groove 2 is formed by folding the bottom of the housing 1. The bottom width of the U-shaped groove 2 is 23 mm, the depth is 25 mm, and the length is 200 mm.

[0028] The drawer body 5 is a rectangular parallelepiped structure, with a hollowed-out lower portion. In this embodiment, the drawer body 5 is a box-like structure made of sheet metal with four double-bent sides and a hollowed-out bottom. The drawer body 5 is 22mm thick and 200mm wide, with the length adjusted based on actual usage needs.
