Description

Technical Field

[0001] The utility model relates to the technical field of distribution box accessories, in particular to a combined ventilation protection cover plate for a distribution cabinet. Background Art

[0002] The distribution box cabinet will emit a lot of heat during operation. In order to ensure the safe operation of the distribution box cabinet, vents are generally opened on the side of the distribution box cabinet. The built-in ventilation fan will draw the hot air in the distribution station to the outside to achieve the purpose of ventilation.

[0003] At present, in order to prevent dust, small animals or insects from entering the distribution box through the vents, a common practice is to install protective devices on the vents. For example, CN205430831U discloses a new dust and heat dissipation device for an electric meter box, which has good effects of blocking small animals, large debris and heat dissipation. However, since the sizes of distribution boxes are different, the vents thereon are also different sizes. In order to achieve a good blocking effect, ventilation protective devices of different specifications and sizes need to be customized according to different distribution cabinets. This will result in a wide variety of ventilation protective devices with poor adaptability and versatility, which will cause a waste of manpower and material resources.

[0004] Therefore, it is urgent for those skilled in the art to develop a ventilation protection device that is adaptable to a variety of sizes and has good versatility. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: The utility model is a combined ventilation and protective cover plate for a distribution cabinet, comprising a cover plate body and an inner plate arranged on the inner side of the cover plate body, the cover plate body is provided with a ventilation structure, the inner plate is provided with a breathable structure, the inner side of the cover plate body is also provided with a support frame, the inner plate is connected to the cover plate body through the support frame, and the outer side of the periphery of the support frame is provided with mutually adaptable splicing structures.

[0007] A further improvement is that the splicing structure is a snap groove and a snap protrusion that are arranged on adjacent outer sides of the support frame to fit together.

[0008] A further improvement is that the buckle groove is configured as a dovetail groove structure, and the buckle protrusion is configured as a dovetail-shaped slider structure that is adaptably connected to the dovetail groove structure.

[0009] A further improvement is that a stepped installation through hole adapted to the air-permeable structure is provided at the center of the support frame, and a mounting groove for a sealing ring is also provided on the side of the support frame away from the cover body.

[0010] A further improvement is that the ventilation structure is a triangular or arc-shaped structure with an upper end opened on the outer side of the cover body and connected to the cover body and an open lower end.

[0011] A further improvement is that the air-permeable structure is provided as a dust-proof mesh structure.

[0012] A further improvement is that: the cover plate body and the support frame are provided with a plurality of symmetrically distributed through-connecting holes.

[0013] A further improvement is that a matching cap is also provided on the connecting hole.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The ventilation protection combined cover plate of the present application has a reserved splicing structure, which can be assembled into a larger ventilation cover plate. It is flexible in application and can be used individually or in combination. It is suitable for ventilation holes of various sizes and has good adaptability. It is quick and convenient to fold and assemble. It can be fastened and connected by bolts and nuts, or glued. It can also be waterproof, rainproof, insect-proof, and prevent solids from entering, ensuring ventilation and heat dissipation of the distribution cabinet, and improving the safety of the distribution cabinet. At the same time, the combined ventilation protection cover plate can also be directly installed on the cabinet body or the house as a window. BRIEF DESCRIPTION OF THE DRAWINGS
