[0036] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] Due to the existence of vents on the cabinet, in actual use scenarios, dust, flying insects or debris from the external environment will enter the cabinet through the vents, affecting the normal operation of the power devices in the cabinet. Therefore, it is necessary to add a dustproof structure at the location of the vents to prevent dust, flying insects or debris from entering the cabinet through the vents.

[0041] In the prior art, bolts are usually used to fix screens or shutters on the vents to achieve dust-proof effect on the vents. However, the fixing form of the screens and shutters is not only too simple in structure, but also causes sand, dust, flying insects or debris to enter the cabinet through the vents again if it is not maintained in time, thereby affecting the dust-proof effect of the air entering the cabinet.

[0042] In order to solve the above problems, Figure 1 to Figure 3 As shown, this embodiment provides a dustproof device 1000. The dustproof device 1000 includes a protective cover assembly 100 and a plurality of dustproof assemblies, wherein the protective cover assembly 100 is arranged outside the cabinet 2000, at least two dustproof assemblies are arranged in sequence along a first direction, the dustproof levels of at least two dustproof assemblies are the same, and / or the dustproof levels of at least two dustproof assemblies gradually increase along the first direction toward the cabinet 2000, and external gas can enter the interior of the cabinet 2000 after passing through at least two dustproof assemblies in sequence, and the dustproof assemblies are arranged in the protective cover assembly 100 and are detachably connected to the protective cover assembly 100.

[0043] The dustproof device 1000 is provided with at least two groups of dustproof components in the protective cover component 100, so that the dustproof level of the two groups of dustproof components is the same, and / or the dustproof level gradually increases along the arrangement direction toward the cabinet 2000, so that the external gas can perform multi-layer dustproof before entering the cabinet 2000, effectively improving the dustproof effect of the air entering the cabinet 2000, and by ensuring that the dustproof component and the protective cover component 100 are detachably connected, it is easy to replace the dustproof component and facilitate subsequent inspection and maintenance. In addition, since the protective cover component 100 is arranged on the outside of the cabinet 2000, it is further easy to replace the dustproof component in the protective cover component 100, and the efficiency of disassembly and assembly of the dustproof component is further improved.

[0044] It should be noted that, in this embodiment, the dustproof device 1000 includes two groups of dustproof components, which are respectively a first dustproof component 200 and a second dustproof component 300 which are sequentially arranged along a first direction toward the cabinet 2000. In other embodiments, the specific number of dustproof components in the dustproof device 1000 can also be adjusted according to actual needs, and this embodiment does not specifically limit it.

[0045] In addition, in this embodiment, since the first dustproof component 200 and the second dustproof component 300 are sequentially arranged along the first direction toward the cabinet 2000, in order to further improve the dustproof effect of the gas entering the cabinet 2000, a shutter is arranged in the first dustproof component 200, and a gauze is arranged in the second dustproof component 300. The shutter and the gauze are sequentially arranged along the first direction, and the dustproof effect of the shutter and the gauze is increased by the arrangement mode, so as to realize the graded dustproof of the gas entering the cabinet 2000. In other embodiments, shutters or other dustproof structures can also be arranged in both the first dustproof component 200 and the second dustproof component 300, or gauze or other dustproof structures can be arranged in both the first dustproof component 200 and the second dustproof component 300, and this embodiment does not make specific limitations.

[0046] As an optional solution, the protective cover assembly 100 is provided with an air outlet 114 and an air inlet 112, at least two groups of dustproof assemblies and the air outlet 114 are sequentially arranged along the first direction, the air inlet 112 and the first dustproof assembly 200 and the second dustproof assembly 300 are arranged along the second direction, and the first direction is different from the second direction. It should be noted that in this embodiment, the first direction is the left-right direction, the second direction is the up-down direction, at least two groups of dustproof assemblies and the air outlet 114 are sequentially arranged along the front-to-back direction, the air inlet 112 and at least two groups of dustproof assemblies are arranged along the up-down direction, and the air inlet 112 is arranged downward. By setting the air inlet 112 downward along the up-down direction, the air needs to move upward and pass through the first dustproof assembly 200 and the second dustproof assembly 300 before it can enter the cabinet 2000 along the vent 2100. As the air moves upward, sand or debris with larger weight and volume in the air will drop under the action of its own gravity and thus cannot reach the first dustproof component 200 and the second dustproof component 300, thereby achieving preliminary filtration of the air entering the first dustproof component 200 and the second dustproof component 300.

[0047] In this embodiment, an air outlet 114 is provided on the rear end of the protective cover assembly 100, and a vent 2100 is provided on the front end of the cabinet 2000. The air outlet 114 and the vent 2100 are arranged opposite to each other in the front-to-back direction, so that the external gas moves upward along the air inlet 112 and moves backward after passing through the first dustproof assembly 200 and the second dustproof assembly 300, and finally enters the interior of the cabinet 2000 along the vent 2100. In other embodiments, the air outlet 114 on the protective cover assembly 100 can also be set at its left end, right end or front end, and the vent 2100 on the cabinet 2000 can also be set at its left end, right end or rear end, which is not specifically limited in this embodiment.

[0048] Furthermore, the protective cover assembly 100 is provided with a plug-in slot extending along the third direction, and a plug-in interface 111 is provided at one end of the plug-in slot, and the first dustproof assembly 200 and the second dustproof assembly 300 can both be inserted into the plug-in slot through the plug-in interface 111, and the third direction and the first direction are perpendicular to each other in the horizontal plane. By providing the plug-in slot extending along the second direction on the protective cover assembly 100, and providing the plug-in interface 111 at one end of the plug-in slot, so that the first dustproof assembly 200 and the second dustproof assembly 300 can be inserted into the plug-in slot through the plug-in interface 111, a guide can be provided for the first dustproof assembly 200 and the second dustproof assembly 300 to be inserted into the protective cover assembly 100.

[0049] It should be noted that, in this embodiment, the third direction is the left-right direction, the first dustproof assembly 200 and the second dustproof assembly 300 are arranged in sequence along the front-back direction, the plug-in slot extends along the left-right direction, and the left end of the plug-in slot is provided with a plug-in port 111. The first dustproof assembly 200 and the second dustproof assembly 300 can be inserted into the protective cover assembly 100 to the left along the plug-in port 111 or can be pulled out from the protective cover assembly 100 to the left along the plug-in port 111. In other embodiments, the first direction and the second direction can also be any two directions perpendicular to each other in the horizontal plane, which is not specifically limited in this embodiment.

[0050] In addition, in other embodiments, the first dustproof component 200 and the second dustproof component 300 can also be detachably arranged in the protective cover component 100 by magnetism, snaps or other fixed directions, which is not specifically limited in this embodiment.

[0051] Specifically, the protective cover assembly 100 includes a protective cover body 110 and a docking plate 120, wherein the protective cover body 110 is provided with a plug-in port 111 and an air inlet 112, and the upper and lower ends of the protective cover body 110 are fixed with docking plates 120, and the docking plates 120 are configured to be fixed to the cabinet 2000, and the docking plates 120 are provided with a plug-in slot extending in the left-right direction, and the first dustproof assembly 200 and the second dustproof assembly 300 are overlapped on the docking plate 120 at the lower end of the protective cover body 110. Fixing the protective cover body 110 and the cabinet 2000 by the docking plate 120 can improve the structural strength between the protective cover body 110 and the cabinet 2000, and also provide stable support for the accommodation of the first dustproof assembly 200 and the second dustproof assembly 300 in the protective cover assembly 100.

[0052] It should be noted that, in this embodiment, since the dustproof assembly includes the first dustproof assembly 200 and the second dustproof assembly 300, the plug-in slot includes the first plug-in slot 130 and the second plug-in slot 140, and the first plug-in slot 130 and the second plug-in slot 140 are sequentially arranged in the front-to-back direction toward the direction close to the cabinet 2000, and the first plug-in slot 130 is arranged corresponding to the first dustproof assembly 200, and the second plug-in slot 140 is arranged corresponding to the second dustproof assembly 300. In other embodiments, the specific number of the plug-in slots can be adjusted according to the specific number of the dustproof assemblies, and this embodiment does not specifically limit it.

[0053] In addition, in this embodiment, since docking plates 120 are provided at both upper and lower ends of the protective cover body 110, the two docking plates 120 are provided with first plug-in slots 130 and second plug-in slots 140, the two first plug-in slots 130 are arranged opposite to each other in the up and down directions, the two second plug-in slots 140 are arranged opposite to each other in the up and down directions, the first dustproof component 200 is clamped between the two first plug-in slots 130, and the second dustproof component 300 is clamped between the two second plug-in slots 140, so as to further improve the guiding effect of the first dustproof component 200 and the second dustproof component 300.

[0054] To further facilitate the assembly and disassembly of the first dustproof assembly 200 and the second dustproof assembly 300 with the protective cover body 110, the first dustproof assembly 200 includes a first dustproof body 220 and a first handle 210 disposed thereon, and the second dustproof assembly 300 includes a second dustproof body 320 and a second handle 310 disposed thereon. By providing the first handle 210 on the first dustproof body 220, it is convenient for the staff to drive the first dustproof assembly 200 to extend into the protective cover body 110 along the plug-in port 111 or to be pulled out from the protective cover body 110 along the plug-in port 111; by providing the second handle 310 on the second dustproof body 320, it is convenient for the staff to drive the second dustproof assembly 300 to extend into the protective cover body 110 along the plug-in port or to be pulled out from the protective cover body 110 along the plug-in port 111.

[0055] It should be noted that, in this embodiment, the plug port 111 is opened on the left side wall of the protective cover body 110. To ensure that the staff can smoothly grasp the first handle 210 and the second handle 310, the first handle 210 is arranged on the left side of the first dustproof component 200, and the second handle 310 is arranged on the left side of the second dustproof component 300.

[0056] Further, the protective cover assembly 100 also includes a first fixing member (not shown in the figure), wherein the end surface of the docking plate 120 close to the cabinet 2000 is provided with a first fixing hole 121, and the cabinet 2000 is provided with a first docking hole 2200, the first fixing hole 121 and the first docking hole 2200 are coaxially arranged, and the first fixing member can be sequentially penetrated and fixed with the first fixing hole 121 and the first docking hole 2200. By using the first fixing member to be sequentially penetrated and fixed with the first fixing hole 121 on the docking plate 120 and the first docking hole 2200 on the cabinet 2000, the docking plate 120 can be fixed to the cabinet 2000, thereby achieving the fixing of the protective cover assembly 100 to the cabinet 2000. It should be noted that in this embodiment, the first fixing member is a rivet nut. After the rivet nut is sequentially penetrated through the first fixing hole 121 and the first docking hole 2200, it is simultaneously riveted and fixed with the first fixing hole 121 and the first docking hole 2200. The riveting nut has a good fixing effect, is easy to assemble, and meets various design requirements. In other embodiments, the first fixing member can also be a bolt and a nut, the bolt is sequentially inserted through the first fixing hole 121 and the first docking hole 2200, and then the nut and the bolt are fixed to fix the docking plate 120 and the cabinet 2000, which is not specifically limited in this embodiment.

[0057] In addition, if Figure 2 As shown, the shield assembly 100 also includes a second fixing member (not shown in the figure), wherein a second fixing hole is provided at the side end of the docking plate 120, and a first locking hole 113 is provided on the side wall of the shield body 110, the second fixing hole and the first locking hole 113 are coaxially arranged, and the second fixing member can be sequentially penetrated and fixed with the second fixing hole and the first locking hole 113. The second fixing member is sequentially penetrated and fixed with the first locking hole 113 on the shield body 110 and the second fixing hole on the side wall of the docking plate 120, so as to achieve stable fixation of the shield body 110 and the docking plate 120. It should be noted that, in this embodiment, the second fixing member is a bolt and a nut, and the bolt is sequentially penetrated through the second fixing hole and the first locking hole 113, and then fixed with the nut and the bolt, so as to fix the docking plate 120 and the shield body 110, so as to achieve detachable fixation of the shield body 110 and the docking plate 120, so as to facilitate the subsequent inspection and maintenance of the shield body 110 and the docking plate 120. In other embodiments, this embodiment is not specifically limited.

[0058] As an optional solution, the dustproof device 1000 further includes a blocking plate 400, wherein the blocking plate 400 is used to block the plug interface 111, so as to restrict the first dustproof component 200 and the second dustproof component 300 on the docking plate 120 from being withdrawn from the plug interface 111. After the first dustproof component 200 and the second dustproof component 300 are pushed into the protective cover body 110 along the plug interface 111, the plug interface 111 is blocked by the blocking plate 400, so as to prevent the first dustproof component 200 and the second dustproof component 300 from sliding out of the protective cover body 110 along the plug interface 111 due to external force during subsequent working processes, thereby ensuring the dustproof effect of the first dustproof component 200 and the second dustproof component 300 on the vent 2100.

[0059] Furthermore, the shield assembly 100 also includes a third fixing member, wherein a third fixing hole 410 is provided on the blocking plate 400, and a second locking hole is provided on the shield body 110, the third fixing hole 410 is coaxially arranged with the second locking hole, and the third fixing member can be sequentially penetrated and fixed with the third fixing hole 410 and the second locking hole. By sequentially penetrating and fixing the third fixing hole 410 on the blocking plate 400 and the second locking hole on the shield body 110, the shield body 110 and the blocking plate 400 are stably fixed, ensuring that the blocking plate 400 fully blocks the plug interface 111. It should be noted that, in this embodiment, the third fixing member is a bolt and a nut. The bolt is sequentially inserted through the third fixing hole 410 and the second locking hole, and then fixed with the nut and the bolt, thereby fixing the sealing plate 400 to the protective cover body 110, thereby realizing the detachable fixation of the protective cover body 110 and the sealing plate 400. When it is necessary to replace the first dustproof component 200 or the second dustproof component 300, the sealing plate 400 can be removed from the avoidance hole 111 of the protective cover body 110, and then the first dustproof component 200 or the second dustproof component 300 can be replaced, and finally the sealing plate 400 can be re-sealed on the plug interface 111.

[0060] In the actual assembly process, the protective cover body 110 and the docking plate 120 can be assembled and fixed first, and then the assembled protective cover body 110 and the docking plate 120 and the cabinet 2000 can be fixed; or the docking plate 120 and the cabinet 2000 can be fixed first, and then the docking plate 120 and the protective cover body 110 can be fixed. This embodiment does not make specific limitations.

[0061] To further facilitate the fixation of the protective cover assembly 100 and the cabinet 2000, a hanging piece 122 is provided on the end surface of the docking plate 120 close to the cabinet 2000, and a hanging hole 2300 is provided on the cabinet 2000. The hanging piece 122 can be hung and docked with the hanging hole 2300 before the first fixing piece is threadedly fixed with the first fixing hole 121 and the first docking hole 2200. The first fixing hole 121 and the first docking hole 2200 on the docking plate 120 hung on the cabinet 2000 are concentrically arranged, so that the subsequent first fixing piece can fix the docking plate 120 and the cabinet 2000. In addition, by first hanging the docking plate 120 on the cabinet 2000, there is no need to lift the docking plate 120 upward, which can effectively reduce the difficulty of fixing the docking plate 120 and the cabinet 2000 and improve the assembly efficiency.

[0062] Specifically, the hanging member 122 extends outward and tilts downward, and the hanging hole 2300 is matched with the hanging member 122. By setting the hanging member 122 to extend outward and tilt downward, when the hanging member 122 is inserted into the hanging hole 2300 matched therewith, if the hanging member 122 wants to be pulled out of the hanging hole 2300, it needs to be lifted upward while being pulled out, which can effectively prevent the hanging member 122 from being separated from the hanging hole 2300, thereby ensuring the assembly safety of the docking plate 120 and the cabinet 2000.

[0063] This embodiment also provides a power control device. The power control device includes a power device, a fan, a cabinet 2000 and the above-mentioned dustproof device 1000, wherein the power device and the fan are both accommodated in the cabinet 2000, the fan is used to blow air to the power device, the vent 2100 can ensure the circulation of air inside and outside the cabinet 2000, and the dustproof device 1000 is fixed on the outside of the vent 2100 on the cabinet 2000. By applying the above-mentioned dustproof device 1000, the power control device can effectively improve the dustproof effect of the air entering the cabinet 2000, and facilitate the replacement of the dustproof component, which is convenient for subsequent inspection and maintenance.

[0064] Furthermore, if Figure 4 As shown, a plurality of vents 2100 are provided on the cabinet 2000, and a dustproof device 1000 is fixed on the outside of each vent 2100. By fixing the dustproof device 1000 on the outside of each vent 2100, the dustproof effect of the air entering the cabinet 2000 can be further guaranteed, thereby improving the protection of the power control device. It should be noted that, in the present embodiment, three vents 2100 are provided on the cabinet 2000, and the three vents 2100 are spaced apart in the up and down directions, and a dustproof device 1000 is fixed on the outside of each vent 2100. In other embodiments, the specific number of vents 2100 and the setting positions between the plurality of vents 2100 can be adjusted according to actual needs, and this embodiment does not make specific limitations.
