Description

Technical Field

[0001] This utility model relates to the field of electrical dust removal, and in particular to a self-cleaning dustproof device for electrical equipment. Background Technology

[0002] With social development, all kinds of electrical equipment are ubiquitous in our lives. As the service life of electrical equipment continues to increase, related maintenance needs also arise. For example, after a long period of use, dust will accumulate on electrical equipment. If dust accumulates on the heat dissipation part of the equipment, it will cause overheating and other adverse conditions, thus affecting the normal operation of the equipment.

[0003] Currently, dust prevention for electrical equipment mainly relies on fans and dust filters, which are available in detachable and integrated dust filter structures. Integrated structures are easy to install during assembly, but maintenance requires removing the entire equipment or dust filter structure from its installation location before cleaning the fan and dust filter, resulting in higher labor and time costs. Detachable structures, on the other hand, design the external dust protection solution as a separate sheet metal structure, using screws or other fastening methods to fix and disassemble the dust filter structure. Compared to integrated structures, this makes maintenance more convenient, but the separate dust filter structure has a greater impact on the stability of the main dust filter structure, making the overall integrity of integrated structures poorer.

[0004] Under the above two dust prevention methods, most of the dust, lint and other debris will still accumulate in various parts of the equipment after long-term use or in harsh environments. If not cleaned for a long time, the blockage will have a significant impact on the heat dissipation of the equipment, affecting the overall performance and lifespan of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning dustproof device for electrical equipment in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A self-cleaning dustproof device for electrical equipment includes a main dustproof housing, a top eaves-type dustproof net assembly, and a fan assembly. The fan assembly is installed inside the main dustproof housing. The top of the main dustproof housing has a sloping surface, and a top dustproof net is fixedly mounted on the sloping surface. Several eaves-type flow guiding structures are installed in a row inside the cavity of the top dustproof net. Several bent window holes are opened on the sloping surface. Guide bending plates are connected to the hole edges on both sides of the bent window holes. First guide bending plates are provided on both sides of the eaves-type flow guiding structures, and the eaves-type flow guiding structures are pressed against the guide bending plates.

[0008] Furthermore, the fan assembly consists of a fan rail, a fan bracket slidably mounted on the fan rail, and a plurality of fans fixed on the fan bracket, wherein the fan rail is fixed inside the main housing of the dustproof mechanism.

[0009] Furthermore, an external fan mounting hole is provided on the main housing of the dustproof mechanism on one side of the fan assembly, and an external fan cover is installed on the external fan mounting hole.

[0010] Furthermore, an ear slot is provided at the bottom edge of the slope surface, and a limiting ear is connected to the top dustproof cover. The limiting ear is inserted into the ear slot and fixed to the main housing of the dustproof structure.

[0011] Furthermore, a top edge fixing hole is provided at the top edge of the slope surface, and one side of the top dustproof cover net is fixed to the top edge fixing hole by fasteners.

[0012] Furthermore, the first guide bending plate is provided with a plurality of linearly arranged heat dissipation holes for the flow guiding structure, and the holes are provided with a plurality of linearly arranged heat dissipation holes along the bending of the guide bending plate.

[0013] Furthermore, the top dustproof cover has several dustproof cover heat dissipation holes arranged in a regular array.

[0014] Furthermore, several drainage grooves are provided on the bottom edge of the top dustproof cover net.

[0015] Furthermore, the top of the dustproof cover net is either flat or inclined at an angle consistent with the inclination angle of the slope surface.

[0016] Furthermore, the first guide bending plate is a trapezoidal guide bending plate.

[0017] The beneficial effects of this utility model are as follows: It consists of two parts: a top eaves-type dustproof scheme structure and a dustproof device main structure. The top eaves air duct structure solves the problem of external dust accumulation requiring manual cleaning.

[0018] The dustproof netting on the top eaves features an array mesh design, enhancing its aesthetics while ensuring overall stability. The eaves structure below the netting and the trapezoidal bend of the main dustproof body utilize different degrees of overlap and bending angles in the mesh to achieve dustproofing without affecting heat dissipation. Falling dust can be washed away by rainwater through the drainage channels of the eaves dustproof netting, achieving a self-cleaning effect. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figure 1 - Figure 9 As shown, a self-cleaning dustproof device for electrical equipment includes a dustproof structure main cover housing 100, a top eaves-type dustproof net assembly 200, and a fan assembly 300.

[0035] The fan assembly 300 is installed inside the dustproof structure main cover housing 100, which has a U-shaped structure to ensure the neatness of the dustproof structure main cover housing 100 after it is used for the electrical equipment body 400.

[0036] The top of the main dustproof cover 100 is provided with a sloping surface 130, and a top dustproof cover net 210 is fixedly covered on the sloping surface 130. Several roof-type flow guiding structural components 220 arranged in a row are installed inside the cover cavity of the top dustproof cover net 210.

[0037] Several bent window holes 131 are provided on the slope surface 130, and a hole edge guide bent plate 110 is connected to both sides of the bent window hole 131.

[0038] The eaves-type flow guide structure 220 has first guide bending plates 222 on both sides. The bending degree of the first guide bending plates 222 matches that of the hole edge guide bending plates 110. The bending angle, opening size and number are determined according to the heat dissipation requirements and dust prevention requirements. The eaves-type flow guide structure 220 adopts a tile-type structure design. It is fixed by the top dustproof cover net 210 and laid on the hole edge guide bending plate 110 so that the first guide bending plates 222 on both sides match the hole edge guide bending plates 110 to achieve the effects of self-cleaning dust prevention and heat dissipation.

[0039] In one embodiment, the first guide bending plate 222 is a trapezoidal guide bending plate (e.g., Figure 3 , Figure 6 As shown), in other embodiments, the first guide bending plate 222 may be a guide bending plate of other shapes, such as Figure 9 As shown, etc.

[0040] like Figure 1 - Figure 9 As shown, this utility model also discloses the following more optimized specific structures:

[0041] The fan assembly 300 consists of a fan rail 330, a fan bracket 320 slidably mounted on the fan rail 330, and several fans 310 fixed on the fan bracket 320. The fan rail 330 is fixed inside the main housing 100 of the dustproof mechanism.

[0042] An external fan mounting hole is provided on the main housing 100 of the dustproof mechanism on one side of the fan assembly 300. An external fan cover 120 is installed on the external fan mounting hole. It can be detached and installed by screws, which facilitates the disassembly and replacement of the internal fan assembly 300.

[0043] An ear slot 132 is provided at the bottom edge of the slope surface 130. A limiting ear 215 is connected to the top dustproof cover mesh 210. The limiting ear 215 is inserted into the ear slot 132 to achieve limiting. The limiting ear 215 is fixed on the dustproof structure main cover shell 100. It can be fixed by fasteners such as press-fit fasteners 214 and screw fasteners.

[0044] A top edge fixing hole is provided at the top edge of the slope surface 130. One side of the top dustproof cover net 210 is fixed to the top edge fixing hole by fasteners, such as screws.

[0045] The fixing methods of the top dustproof cover 210 and the eaves-type flow guide structure 220 include, but are not limited to, fastener connection or welding. The eaves-type flow guide structure 220 is provided with a top hole 221 to facilitate fastener connection.

[0046] The first guide bending plate 222 is provided with a number of linearly arranged heat dissipation holes 223 for the flow guiding structure, and the hole-edge guide bending plate 110 is provided with a number of linearly arranged hole-edge bending heat dissipation holes 111. The overlap between the hole-edge bending heat dissipation holes 111 and the heat dissipation holes 223 for the flow guiding structure is determined according to actual needs, so as to ensure dust prevention while taking into account the heat dissipation performance of the equipment.

[0047] The top dustproof cover mesh 210 has several dustproof cover heat dissipation holes 212 arranged in a regular array. The shape and size of the holes are not limited, depending on the heat dissipation and dustproof performance, and their main function is to exhaust air.

[0048] Several drainage grooves 213 are provided on the bottom edge of the top dustproof cover net 210.

[0049] like Figure 1 - Figure 9 The self-cleaning dustproof device for electrical equipment shown is installed together with the main body 400 of the electrical equipment by fasteners. The arrangement of the first guide bending plate 222 and the hole-edge guide bending plate 110 can be specifically referred to. Figure 7 and Figure 8 ,in, Figure 7Two distribution arrangements of the two are shown. Figure 8 Another arrangement of the two is shown, which can better achieve water conduction and heat dissipation;

[0050] Understandably, the ear slot 132 and the limiting ear 215 can be set or removed as needed. Specifically, they can be set or removed according to the shape of the first guide bending plate 222 and the hole-along guide bending plate 110. For example, when the first guide bending plate 222 and the hole-along guide bending plate 110 are... Figure 7 When the shape is such that the ear slot 132 and the limiting ear 215 are omitted, that is, the ear slot 132 and the limiting ear 215 are not required; when the first guide bending plate 222 and the hole are along the guide bending plate 110 are Figure 8 When the shape is such that a corresponding ear slot 132 and a limiting ear 215 are required, for example, this utility model Figure 3 As shown in the diagrams and described above.

[0051] During overall operation, the fan 310 blows air upwards in a positive direction, passing through the dustproof structure main cover housing 100 and the top eaves-type dustproof net assembly 200, and is blown out from the top dustproof cover net 210 position. The entire air duct system has a large flow area, thereby improving the heat dissipation effect, and also has a certain dust removal effect. The air duct system is reasonably designed, stable and reliable.

[0052] The overall dust accumulation maintenance solution is as follows: Firstly, when external dust accumulates on the top eaves-type dustproof net assembly 200 and the main dustproof structure housing 100, natural liquids such as rainwater can be used to clean the top eaves-type dustproof net assembly 200 and the main dustproof structure housing 100 naturally. Alternatively, the equipment can be rinsed with high-pressure water jets, and the dust flows out from the drain trough 213 with the water flow, achieving a deep cleaning effect on the equipment without removing the main dustproof structure housing 100. Dust and other impurities fall onto the top dustproof net 210 (the angle of the net is not limited; it can be horizontal, vertical, or inclined), and some dust falls onto the main dustproof structure housing 100 through the dustproof net heat dissipation holes 212. The overlap of the bent heat dissipation holes 111 and the heat dissipation through holes 223 of the air guiding structure is determined according to actual needs, ensuring dust prevention while also taking into account the heat dissipation performance of the equipment. This dust prevention solution has a long maintenance cycle and improves user-friendliness.

[0053] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
