Description

TECHNICAL FIELD

[0001] The present application relates to the field of cabinets, in particular to a filtering structure and a cabinet. BACKGROUND

[0002] A cabinet is a housing for accommodating electronic and electrical equipment, which provides protection against water, dust, electromagnetic interference, etc. for the stored objects inside.

[0003] Electronic and electrical equipment will emit heat during operation. In order to ensure the operating performance of the electronic and electrical equipment, a heat dissipation opening is provided on the cabinet to facilitate air circulation for heat dissipation. In order to prevent foreign matter from entering, a filtering structure is provided on the heat dissipation opening.

[0004] The filtering structure usually needs to be disassembled for regular maintenance. In the related art, the filtering structure is mostly pressed into the inner wall of the cabinet body by a sealing plate. When disassembled, the internal space of the cabinet body needs to be borrowed, which results in that the filtering structure can only be arranged on the side of the electronic and electrical equipment, and it is difficult to directly blow the electronic and electrical equipment, so the heat dissipation efficiency is low. CONTENT OF THE INVENTION

[0005] The present application provides a filtering structure and a cabinet to provide higher heat dissipation efficiency while ensuring convenient disassembly.

[0006] A filtering structure comprises: a mounting piece comprising a mounting frame having two edge frames opposite in a predetermined direction; a supporting piece arranged on the inner wall of the mounting frame, the supporting piece extending along the predetermined direction; a filtering assembly slidingly arranged on the supporting piece along the predetermined direction, comprising a folding mesh plate and a flexible filter layer, the flexible filter layer being arranged on the side of the folding mesh plate facing the supporting piece; wherein the folding mesh plate comprises a plurality of sub-plates connected to each other in sequence along the predetermined direction, and the adjacent sub-plates are foldably arranged.

[0007] The above technical solution can be understood as follows: in the related prior art, the filtering assembly cannot be deformed and can only be removed as a whole, which occupies a large amount of internal space of the cabinet during removal; if the filtering structure is installed between the heat source and the inner wall of the cabinet, the heat source will block the filtering structure, so that the filtering structure is difficult to remove; therefore, in the related art, the filtering structure can only be placed in an area outside the heat source, which makes it difficult for cooling air to directly blow on the heat source, thereby reducing the heat dissipation efficiency. Therefore, in the present application, the filtering assembly can be folded, which makes it possible to remove the filtering assembly from one end of the mounting frame. The specific operation process is as follows: the folding screen plate is disassembled from the mounting frame, the sub-plate at one end of the folding screen plate is rotated around the hinge shaft, and then the sub-plate at the end is pulled out. During the pulling-out process, the other sub-plates are slid on the support along a predetermined direction, until the sub-plate at the end is completely pulled out, and then the folding is performed, and the pulling-out process of the next sub-plate is continued, and finally the filtering assembly is completely pulled out. Due to the folding structure design of the folding screen plate, the filtering assembly occupies less internal space of the cabinet during removal, so that the filtering structure of the present application can be directly opposite to the heat source when installed in the cabinet, and the cooling air can be in more comprehensive contact with the heat source, thereby improving the heat dissipation efficiency.

[0008] As one of the optional embodiments of the present application, a fixing member is connected to the inner wall of any of the frames, and the fixing member is located on the side of the filtering assembly close to the support and is bolted to the folding screen plate.

[0009] The above technical solution proposes a specific structure of the folding screen plate disassembled from the mounting frame. The fixing member is arranged on the side of the filtering assembly close to the support, so that the fixing member does not interfere with the pulling-out and folding process of the filtering assembly, thereby ensuring smooth pulling-out of the filtering assembly.

[0010] As one of the optional embodiments of the present application, a first limiting member is connected to the inner walls of the two frames in the predetermined direction, and the first limiting member is located on the side of the filtering assembly away from the support.

[0011] As one of the optional embodiments of the present application, a second limiting member is connected to the inner walls of the mounting frame at both ends of the rotation axis of the sub-plate, and the second limiting member is located on the side of the filtering assembly away from the support.

[0012] The first limiting member and the second limiting member effectively limit the filtering assembly at positions other than the end of the filtering assembly close to the fixing member, thereby stably limiting the filtering assembly under the premise of reducing the bolted structure, reducing the workload of disassembling the folding screen plate, and ensuring the stability of the connection between the filtering assembly and the mounting frame during transportation or vibration of the cabinet, thereby reducing the jolting of the filtering assembly and maintaining the normal use performance of the filtering assembly.

[0013] As one of the optional embodiments of the present scheme, a pulling piece is arranged on the folding net plate. In the predetermined direction, the pulling piece is arranged at one end of the folding net plate close to the fixing piece, and the pulling piece is arranged on the side of the folding net plate away from the supporting piece.

[0014] As one of the optional embodiments of the present scheme, a buffer piece is arranged on the folding net plate. In the predetermined direction, the buffer piece is arranged at one end of the folding net plate close to the first limiting piece, and the buffer piece is arranged on the side of the folding net plate away from the supporting piece.

[0015] The above technical scheme is realized. The pulling piece makes it easier for the operator to drag the folding net plate, thereby improving the convenience and flexibility of operation. The buffer piece reduces the direct collision between the folding net plate and the first limiting piece, thereby reducing the damage to the folding net plate and improving the service life.

[0016] As one of the optional embodiments of the present scheme, the filter assembly further comprises a pressing plate arranged on the side of the flexible filter layer away from the folding net plate, and the pressing plate is bolted to the folding net plate to press and fix the flexible filter layer to the folding net plate.

[0017] As one of the optional embodiments of the present scheme, the side of the folding net plate facing the flexible filter layer is provided with a threaded stud, the threaded stud penetrates the flexible filter layer and the pressing plate, and the free end of the threaded stud is threadedly connected with a nut.

[0018] As one of the optional embodiments of the present scheme, the flexible filter layer is bonded to the folding net plate.

[0019] The above technical scheme is realized. A connection relationship between the folding net plate and the flexible filter layer is proposed. The flexible filter layer is clamped between the folding net plate and the pressing plate. When disassembly is needed, the filter assembly is taken out as a whole, and then the pressing plate is removed to take down the flexible filter layer, thereby effectively improving the convenience of use. In one optional example, the flexible filter layer is bonded to the folding net plate. Specifically, glue is applied to the side and the middle part of the folding net plate, and the flexible filter layer is press-fitted to the folding net plate. When the flexible filter layer is replaced, the two can be forcibly separated by external force.

[0020] As one of the optional embodiments of the present scheme, the mounting frame has opposite first and second openings, and the second opening is located on the side of the supporting piece away from the filter assembly; the mounting piece further comprises a plurality of support rib plates connected to the second opening, and the support rib plates and the mounting frame jointly form a containing cavity, and the filter assembly is arranged in the containing cavity.

[0021] As one of the optional embodiments of the present scheme, the adjacent sub-plates are hingedly arranged, and the hinge axis of the sub-plate is perpendicular to the predetermined direction.

[0022] A cabinet comprises: a cabinet body having a mounting cavity and a mounting plate with a heat dissipation opening communicated with the mounting cavity; a heat source arranged in the mounting cavity; the filter structure as described above connected to one side of the mounting plate close to the mounting cavity; wherein the mounting frame is arranged around the periphery of the heat dissipation opening, and the projection of the heat dissipation opening on the mounting plate partially overlaps the projection of the heat source on the mounting plate.

[0023] One of the above technical solutions has the following advantages or beneficial effects: in the present application, the filter assembly can be folded, which makes it possible to extract the filter assembly from one end of the mounting frame when the filter assembly is taken out. The specific operation process is as follows: the folding screen plate is disassembled from the mounting frame, the sub-plate at one end of the folding screen plate is rotated around the hinge shaft, and then it is pulled outwards. The sub-plate at the end is pulled out of the mounting frame, and in the process, the other sub-plates are slid on the support along the predetermined direction until the sub-plate at the end is completely pulled out, and then folded, and the pulling-out process of the next sub-plate continues, and finally the filter assembly is completely pulled out. Due to the folding structure design of the folding screen plate, the filter assembly occupies less internal space of the cabinet when it is taken out, so that the filter structure of the present application can be directly faced to the heat source when it is installed in the cabinet, and the cooling air can be more fully contacted with the heat source, thereby improving the heat dissipation efficiency.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the term "and / or" in this paper is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents an "or" relationship between the associated objects without special explanation.

[0041] The following will be described in detail with reference to the drawings in the embodiments of the present application. Figure 1 Further description is made on the related background of the present application.

[0042] Reference Figure 1 is a structural view of the filter structure installed on the cabinet 100 in the related art. The cabinet 100 has a mounting plate 102, and the mounting plate 102 is provided with a heat dissipation opening 104. The shell of the filter structure is bolted to the inner wall of the mounting plate 102, so that the filter structure covers the heat dissipation opening 104.

[0043] The removal process of the above filter structure involves unscrewing the bolts of the filter structure and then moving the entire filter structure perpendicular to the mounting plate 102 to complete the disassembly. This disassembly process occupies a significant amount of internal space in the cabinet 100. If the filter structure is installed face-to-face between the heat source 103 and the mounting plate 102, the heat source 103 will obstruct the filter structure, making it difficult to remove. Therefore, related technologies typically employ methods similar to... Figure 1 As shown, placing the filter structure outside the heat source 103 makes it difficult for the cooling air to blow directly onto the heat source 103, resulting in insufficient heat dissipation efficiency.

[0044] It should be noted that in the usage scenario described in this embodiment, the external reserved space of the cabinet 100 is very small, making it difficult for operators to disassemble the filter structure from the outside. Therefore, it is considered to achieve disassembly and maintenance of the filter structure from the inside of the cabinet 100. In one example, the cabinet is an energy storage converter cabinet, and the heat source 103 is a dry-type transformer. In addition to the dry-type transformer, the cabinet also contains transformers, connecting devices, etc.

[0045] The following is in conjunction with the appendix Figures 2-9 This application will be further described below.

[0046] Reference Figure 2 and Figure 3 The filter structure provided in this application embodiment includes an installation component 1, a filter assembly 3 disposed within the installation component 1, and a barrier net 9 connected to the installation component.

[0047] The mounting component 1 includes a mounting frame 11, and a supporting rib plate 12 and a connecting edge 13 connected to the mounting frame 11. Specifically, combined with Figure 4 The mounting frame 11 is a rectangular frame structure. The mounting frame 11 has two sidewalls that are opposite each other in a predetermined direction X. In this embodiment, the predetermined direction X is the length direction of the mounting frame 11.

[0048] The mounting frame 11 has a first opening 111 and a second opening 112 facing each other. A connecting edge 13 is disposed around the perimeter of the mounting frame 11 at the first opening 111 and extends away from the first opening 111. The connecting edge 13 is used to connect the mounting frame 11 to a carrier, which in one example is a cabinet. Supporting ribs 12 are disposed on the inner wall of the second opening 112. Optionally, multiple supporting ribs 12 are provided. The supporting ribs 12 are strip-shaped and are arranged intersecting each other. The ends of the supporting ribs 12 are connected to the inner wall of the second opening 112. In this way, the mounting frame 11 and the supporting ribs 12 form a cover structure, and the filter assembly 3 is placed inside the mounting component 1.

[0049] The blocking net 9 is arranged on the side of the support rib plate 12 away from the filter assembly 3. In other alternative embodiments, the blocking net 9 can also be arranged on the side of the support rib plate 12 close to the filter assembly 3. Specifically, the blocking net 9 is welded to the support rib plate 12.

[0050] With reference to Figure 3 and Figure 4 , the filter structure further comprises a supporting member 2 arranged on the inner wall of the mounting frame 11. In one example, two supporting members 2 are arranged, which are in the form of guide rails arranged on the inner walls of the two sides of the mounting frame 11 along the predetermined direction X, and extend along the predetermined direction X, and the filter assembly 3 is arranged to slide along the predetermined direction X on the supporting members 2. It should be noted that the supporting members 2 are in the form of guide rails to reduce the material and play a guiding role. It is not excluded that in other alternative examples, the supporting members 2 have other structural forms, for example, in other alternative examples, the supporting members 2 can be in the form of frames, and the circumferential side of the supporting members 2 is connected to the inner wall of the mounting frame 11. The supporting members 2 can only play a role of supporting the filter assembly 3.

[0051] With reference to Figure 3 , Figure 5 and Figure 6 , the filter assembly 3 comprises a folding net plate 31 and a flexible filter layer 32, the flexible filter layer 32 is arranged on the side of the folding net plate 31 facing the supporting member 2, and the folding net plate 31 is detachably connected to the mounting frame 11. The folding net plate 31 comprises a plurality of sub-plates 311 connected to each other in sequence along the predetermined direction X, and the adjacent sub-plates 311 are arranged to be foldable.

[0052] It can be understood that the foldable sub-plates 311 means that two adjacent sub-plates 311 can rotate around an axis, so as to fold towards or away from each other along the rotation direction. In one example, the adjacent sub-plates 311 are hingedly arranged, and the hinge axis of the sub-plates 311 is perpendicular to the predetermined direction X. In other alternative embodiments, the sub-plates 311 can also be connected together by soft material to realize the foldable arrangement, for example, in alternative examples, the sub-plates 311 are connected together by a soft plate, a flexible layer or the like.

[0053] It should be noted that in combination with Figure 6 , the supporting member 2 is designed in the form of U, and the edge of the folding net plate 31 is provided with a folding edge, so that a recessed guide groove is formed on the supporting member 2, and the folding net plate 31 slides in the guide groove through the folding edge, thereby improving the stability of the folding net plate 31.

[0054] The technical scheme is realized, and since the filter assembly 3 is foldable, the filter assembly 3 can be pulled out from one end of the mounting frame 11 when the filter assembly 3 is taken out. The specific operation process is as follows: the folding net plate 31 is detached from the mounting frame 11, the sub-plate 311 at one end of the folding net plate 31 is rotated around the hinge shaft, and then is pulled outwards. The sub-plate 311 at the end is pulled out of the mounting frame 11, and in the process, the other sub-plates 311 are driven to slide on the support 2 along the predetermined direction X until the sub-plate 311 at the end is completely pulled out, and then the folding is performed, and the pulling-out process of the next sub-plate 311 is continued, and finally the filter assembly 3 is completely pulled out. Due to the folding structure design of the folding net plate 31, the internal space of the cabinet 100 is smaller when the filter assembly 3 is taken out, and therefore the filter structure of the present application can be directly faced to the heat source 103 when being installed in the cabinet 100, and the cooling air can be more fully contacted with the heat source 103, thereby improving the heat dissipation efficiency.

[0055] With reference to Figure 5 , Figure 6 and Figure 7 , as one of the optional embodiments of the present application, the filter assembly 3 further comprises a pressing plate 33, which is arranged on the side of the flexible filter layer 32 away from the folding net plate 31, and is bolted to the folding net plate 31 to press and fix the flexible filter layer 32 to the folding net plate 31. Specifically, the side of the folding net plate 31 facing the flexible filter layer 32 is provided with a threaded stud 31a, the threaded stud 31a penetrates the flexible filter layer 32 and the pressing plate 33, and the free end of the threaded stud 31a is threadedly connected with a nut 31b.

[0056] In combination with Figure 7 , the pressing plate 33 is provided with a plurality of plates along the predetermined direction X, each of which extends along the rotation axis of the sub-plate 311, and is detachably connected to the folding net plate 31 through the pressing plate 33. The flexible filter layer 32 is clamped between the folding net plate 31 and the pressing plate 33. When disassembly is needed, the filter assembly 3 is taken out as a whole, and then the pressing plate 33 is removed, so that the flexible filter layer 32 can be taken off, thereby effectively improving the convenience of use.

[0057] It should be noted that the flexible filter layer 32 is only fixed to the folding net plate 31 and can be folded and deformed synchronously with the folding of the folding net plate 31, and is not limited to the bolted press-fit provided in the embodiments of the present application. For example, in one optional example, the flexible filter layer 32 is bonded to the folding net plate 31. Specifically, glue is applied to the side and the middle of the folding net plate 31 to press and fix the flexible filter layer 32 to the folding net plate 31. When the flexible filter layer 32 is replaced, the two can be forcibly separated by external force.

[0058] It can be understood that the flexible filter layer 32 refers to a structure capable of mainly filtering dust, water vapor and other impurities. Optionally, the flexible filter layer 32 is provided as filter cotton, such as synthetic fiber filter material product VNF-290 (G2). In other optional embodiments, the flexible filter layer 32 can also be filter cloth, filter paper, etc.

[0059] With reference to Figures 4-8 As one of the optional embodiments of the present application, a fixing member 4 is further included, which is connected to the inner wall of the mounting frame 11. Specifically, the fixing member 4 can be arranged on any one of the side frames of the mounting frame 11 in the predetermined direction X. In the embodiment of the present application, the fixing member 4 is located on the side of the filter assembly 3 close to the support member 2, and the fixing member 4 is bolted to the folding mesh plate 31.

[0060] To achieve the above technical solution, a specific structure is provided in which the folding mesh plate 31 is detachably connected to the mounting frame 11, and the fixing member 4 is arranged on the side of the filter assembly 3 close to the support member 2. This makes the fixing member 4 not interfere with the extraction and folding process of the filter assembly 3, thereby ensuring smooth extraction of the filter assembly 3.

[0061] With reference to Figure 7 and Figure 8 The fixing member 4 is provided as an L-shaped plate structure, one vertical edge of the fixing member 4 is fixedly connected to the inner wall of the mounting frame 11, and the other horizontal edge of the fixing member 4 is used to bear the folding mesh plate 31. In order to improve the operability of the bolted connection of the folding mesh plate 31, a threaded sleeve 21 is fixedly arranged on the side of the horizontal edge of the fixing member 4 away from the folding mesh plate 31. The bolt is screwed into the threaded sleeve 21, and the end of the bolt abuts against the side of the folding mesh plate 31 away from the fixing member 4.

[0062] With reference to Figure 6 and Figure 7 As one of the optional embodiments of the present application, a first limiting member 5 and a second limiting member 6 are further included. In the predetermined direction X, the fixing member 4 and the first limiting member 5 are respectively connected to the two side frames of the mounting frame 11 in the predetermined direction X, and the first limiting member 5 is located on the side of the filter assembly 3 away from the support member 2. The second limiting member 6 is located on the inner walls of the mounting frame 11 at both ends of the rotation axis of the folding plate 311, and the second limiting member 6 is arranged on the side of the filter assembly 3 away from the support member 2.

[0063] To achieve the above technical solution, the first limiting member 5 and the second limiting member 6 effectively limit the filter assembly 3 at positions other than the end of the fixing member 4. Under the premise of reducing the bolted connection structure, the filter assembly 3 can still be relatively stably limited, thereby reducing the workload of dismounting the folding mesh plate 31. At the same time, the stability of the connection between the filter assembly 3 and the mounting frame 11 is ensured during the transportation process or vibration working condition of the cabinet, thereby reducing the jolting of the filter assembly 3 and maintaining the normal use performance of the filter assembly 3.

[0064] It can be understood that in other optional embodiments, the fixing member 4 can be provided in a number greater than one, as long as the folded screen 31 in the filter assembly 3 is bolted to the fixing member 4. In the case of disassembling the filter assembly 3, the folded screen 31 is only connected to the fixing member 4. In the embodiment of the present application, the fixing member 4 is only provided at one end of the mounting frame 11 to complete the disconnection of the folded screen 31. The position of the other part of the folded screen 31 is limited by the first limiting member 5 and the second limiting member 6. This greatly reduces the workload during disassembly. And because the folded screen 31 is pulled out from the end close to the fixing member 4, the first limiting member 5 and the second limiting member 6 do not affect the pulling of the folded screen 31 while limiting, effectively balancing the needs of operation flexibility and stable limiting.

[0065] As one of the optional embodiments of the present scheme, the folded screen 31 is provided with a pulling member 7. In the predetermined direction X, the pulling member 7 is provided at one end of the folded screen 31 close to the fixing member 4, and the pulling member 7 is provided on the side of the folded screen 31 away from the support member 2. In one example, the pulling member 7 is designed as a handle.

[0066] The folded screen 31 is provided with a buffer member 8. In the predetermined direction X, the buffer member 8 is provided at one end of the folded screen 31 close to the first limiting member 5, and the buffer member 8 is provided on the side of the folded screen 31 away from the support member 2. In one example, the first limiting member 5 and the second limiting member 6 are both designed as L-shaped, and the buffer member 8 is also L-shaped. On the one hand, this shape design makes the first limiting member 5, the second limiting member 6 and the buffer member 8 all have elasticity, reducing the damage caused by collision. On the other hand, the contact surface is arc-shaped, further reducing the damage caused by collision and noise.

[0067] To achieve the above technical scheme, the pulling member 7 makes it easier for the operator to pull the folded screen 31, thereby improving the convenience and flexibility of operation. The buffer member 8 reduces the direct collision between the folded screen 31 and the first limiting member 5, thereby reducing the damage to the folded screen 31 and improving the service life.

[0068] On the other hand, with reference to Figure 9The application further provides a cabinet, which comprises: a cabinet body 100 having a mounting cavity 101 and a mounting plate 102, the mounting plate 102 being provided with a heat dissipation opening 104 communicating with the mounting cavity 101; a heat source 103 arranged in the mounting cavity 101; the filtering structure as described above connected to one side of the mounting plate 102 close to the mounting cavity 101; wherein the mounting frame 11 is arranged around the periphery of the heat dissipation opening 104, and the projection of the heat dissipation opening 104 on the mounting plate 102 partially overlaps the projection of the heat source 103 on the mounting plate 102. In one example, the projection of the heat dissipation opening 104 on the mounting plate 102 is within the range defined by the projection of the heat source 103 on the mounting plate 102.

[0069] In the filtering structure use stage, the cooling air is blown from the front of the filtering structure to the heat source 103, thereby greatly improving the heat dissipation efficiency.

[0070] When the filtering structure needs to be removed, the dismounting process is as follows:

[0071] The folding screen 31 and the fixing member 4 are dismounted;

[0072] The operator opens the cabinet door, reaches out from the inside of the cabinet body 100 to hold the pull member 7, rotates the sub-screen 311 at one end of the folding screen 31 around the hinge shaft, and then pulls outwards along the arrow direction in the drawing, and the sub-screen 311 at the end is pulled out of the mounting frame 11, and in the process, the other sub-screens 311 are slid along the predetermined direction X on the supporting member 2 until the sub-screen 311 at the end is completely pulled out.

[0073] The first pulled-out sub-screen 311 is folded, and the folding process will drive the next sub-screen 311 to be pulled out, and the above process is repeated until the filtering assembly 3 is completely pulled out.

[0074] Since the folding screen 31 is formed by a plurality of sub-screens 311 hingedly connected in sequence, after one sub-screen 311 is pulled out, the remaining sub-screens 311 can be folded on the previous sub-screen 311, thereby greatly reducing the occupation of the internal space of the cabinet body 100. While achieving overall air supply cooling, the filtering assembly 3 can also be smoothly dismounted for maintenance.

[0075] The above is only part of the embodiments of the application, and does not limit the application in any form. The protection scope of the embodiments of the application is not limited thereto, and any person skilled in the art can easily think of simple modifications, equivalent changes and modifications within the technical range disclosed by the embodiments of the application.
