Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] In power systems, distribution cabinets are critical electrical equipment, and their stable operation is essential for ensuring power supply. Traditional distribution cabinets typically employ a bottom-intake and top-exhaust cooling method. This design utilizes the natural convection principle of hot air rising and cold air sinking, effectively dissipating heat from inside the cabinet and ensuring that electrical components operate at suitable temperatures.

[0004] However, the bottom air intake design also brings some problems. Because the bottom air intake is close to the ground, it easily attracts dust and foreign objects. This dust can enter the distribution cabinet under the action of airflow, accumulating on the surface of electrical components, affecting the heat dissipation and insulation performance of the components, and in severe cases, even causing equipment failure. To address this problem, a filter is usually installed at the bottom air intake to filter the air entering the cabinet and block dust and larger particles.

[0005] While filters can reduce dust entry to some extent, they still require regular cleaning and maintenance. Currently, the common practice for cleaning distribution cabinets is to simply remove and wash the filters that need cleaning. However, this method can easily cause dust from the filters to fall into the surrounding environment, causing secondary pollution. This not only poses a threat to the health of operators but also has an adverse impact on the equipment and environment around the distribution cabinet. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings by providing a power distribution cabinet that prevents dust from falling during filter cleaning.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a power distribution cabinet, comprising:

[0008] The cabinet has an air inlet and an air outlet that communicate with the internal cavity of the cabinet, and the air outlet is located at the top of the air inlet;

[0009] Two protective plates are detachably installed at the air inlet and air outlet of the cabinet, respectively, and the protective plates are provided with multiple sieve holes for airflow.

[0010] The filter screen is detachably mounted on the protective plate corresponding to the air inlet and located on the side of the protective plate closer to the cabinet. The filter screen is provided with multiple filtration areas for filtering the air flowing towards the air inlet, and each filtration area is composed of multiple filter holes.

[0011] A cover assembly comprising a plurality of covers slidably disposed on the air inlet side of the filter screen, the covers being movable along the length of the filter screen toward or away from the filtration area.

[0012] Furthermore, a splicing assembly is provided between the guard plate and the cabinet body. The splicing assembly includes two guide sleeves fixedly installed inside the cabinet body and two studs detachably installed on the guard plate. The studs are threadedly connected to the guide sleeves.

[0013] Furthermore, a sealing plate is provided on the stud of the corresponding air inlet. The sealing plate is rotatably connected to the stud and can move synchronously with the stud, which is used to seal the air inlet when the filter screen is removed.

[0014] Furthermore, the corresponding air inlet is provided with two positioning plates that move with the air inlet. The positioning plates are located on the side of the air inlet closer to the cabinet. The filter screen is slidably connected to the positioning plates. The positioning plates are provided with sliding grooves for the filter screen to slide up and down. When the filter screen moves to the lower limit position of the sliding groove and the air inlet is in close contact with the cabinet, the filter screen blocks the air inlet.

[0015] Furthermore, the cover plate assembly also includes connecting strips connected to each cover plate and multiple baffles corresponding to each cover plate. The baffles are fixedly installed on the air inlet side of the filter screen. The multiple cover plates, baffles and filter areas are arranged alternately. Each filter area is located between an adjacent cover plate and a corresponding baffle. A groove is provided on the side of the cover plate near the corresponding baffle. When the cover plate abuts against the corresponding baffle, each filter area is blocked by the cover plate.

[0016] Furthermore, the connecting strip is provided with a locking component for locking the connecting strip. The locking component includes a movable strip located on the air inlet side of the filter and connected to one end of the connecting strip. The movable strip is located outside the moving area of ​​the cover plate. At least one tension spring is provided between the movable strip and the outermost stop strip. When the tension spring is in its natural state, the filter area is not blocked by the cover plate. A first pin seat is provided on the side of the movable strip away from the stop strip. A positioning pin that can move up and down and passes through the first pin seat is provided on the first pin seat. The locking component also includes a second pin seat located on the air inlet side of the filter and a top pusher provided on the corresponding positioning plate. The second pin seat is provided with a hole for the positioning pin to be inserted. When the positioning pin passes through the first pin seat and is inserted into the second pin seat, the filter area is blocked by the cover plate. When the filter moves to the lower limit position of the slide groove, the top pusher passes through the hole and is flush with the top of the second pin seat.

[0017] The beneficial effects of this utility model are reflected in:

[0018] This invention detachably mounts a filter screen onto a corresponding protective plate. After the protective plate is assembled with the cabinet, all air entering the cabinet must first pass through the filter screen. By setting a cover plate assembly that works with the filter screen, when the filter screen needs to be removed for cleaning, the filtration area can be blocked by moving the cover plate before the filter screen can be removed. The cover plate prevents dust on the air intake side of the filter screen from being scattered into the surrounding environment during the removal process, thereby preventing dust from falling during filter screen cleaning.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-8 This utility model discloses a power distribution cabinet, comprising:

[0031] Cabinet 1, which is provided with an air inlet and an air outlet that communicate with the inner cavity of the cabinet 1, with the air outlet located at the top of the air inlet;

[0032] Two protective plates 2 are detachably installed at the air inlet and air outlet of the cabinet 1, respectively. The protective plates 2 are provided with multiple sieve holes for airflow.

[0033] The filter screen 3 is detachably mounted on the guard plate 2 corresponding to the air inlet and is located on the side of the guard plate 2 close to the cabinet 1. The filter screen 3 is provided with multiple filtration areas for filtering the air flowing towards the air inlet, and each filtration area is composed of multiple filter holes.

[0034] The cover assembly 4 includes a plurality of cover plates 41 slidably disposed on the air inlet side of the filter screen 3. The cover plates 41 are movable along the length of the filter screen 3 toward the side closer to or away from the filtration area.

[0035] This utility model, by detachably mounting the filter screen 3 onto the corresponding protective plate 2, ensures that after the protective plate 2 is assembled with the cabinet 1, all air entering the cabinet 1 must first pass through the filter screen 3. By setting a cover plate assembly 4 that cooperates with the filter screen 3, when the filter screen 3 needs to be disassembled and cleaned, the filter area can be blocked by moving the cover plate 41 before the filter screen 3 can be disassembled. The cover plate 41 prevents dust on the air intake side of the filter screen 3 from being scattered into the surrounding environment during the handling process, thereby achieving the purpose of preventing dust from falling during the filter cleaning process.

[0036] In one embodiment, a splicing component 5 is provided between the guard plate 2 and the cabinet 1. The splicing component 5 includes two guide sleeves 51 fixedly disposed in the cabinet 1 and two studs 52 detachably disposed on the guard plate 2. The studs 52 are threadedly connected to the guide sleeves 51.

[0037] This design allows the guard plate 2 to be pushed tightly against the cabinet body 1 by screwing the stud 52 onto the guide sleeve 51 during installation.

[0038] In one embodiment, a sealing plate 6 is provided on the stud 52 of the corresponding air inlet. The sealing plate 6 is rotatably connected to the stud 52 and can move synchronously with the stud 52, and is used to seal the air inlet when the filter screen 3 is disassembled.

[0039] This design ensures that when the protective plate 2 is removed, the stud 52 moves synchronously to the side away from the cabinet 1, thereby moving the sealing plate 6 together to block the air inlet and minimize the amount of dust entering the cabinet 1 through the air inlet during disassembly. When the protective plate 2 is installed, the sealing plate 6 moves with the stud 52 to the side closer to the cabinet 1, thereby detaching from the air inlet and not affecting the entry of external air through the air inlet.

[0040] In one embodiment, the corresponding air inlet guard plate 2 is provided with two positioning plates 7 that move with the guard plate 2. The positioning plates 7 are located on the side of the guard plate 2 close to the cabinet 1. The filter screen 3 is slidably connected to the positioning plates 7. The positioning plates 7 are provided with a sliding groove for the filter screen 3 to slide up and down. When the filter screen 3 moves to the lower limit position of the sliding groove and the guard plate 2 is close to the cabinet 1, the filter screen 3 blocks the air inlet.

[0041] This design allows the filter screen 3 to be inserted into the positioning plate 7 by moving up and down, and to move synchronously with the guard plate 2. When the filter screen 3 needs to be cleaned, it can be quickly removed by pulling it upwards.

[0042] In practice, a sealing strip is provided on the side of the filter screen 3 that contacts the cabinet 1 to further improve the sealing performance of the filter screen 3 during installation.

[0043] In one embodiment, the cover plate assembly 4 further includes a connecting strip 42 connected to each cover plate 41 and a plurality of baffles 43 corresponding to each cover plate 41. The baffles 43 are fixedly disposed on the air inlet side of the filter screen 3. The plurality of cover plates 41, baffles 43 and filter areas are arranged alternately. Each filter area is located between adjacent cover plates 41 and corresponding baffles 43. A groove is provided on the side of the cover plate 41 near the corresponding baffle 43. When the cover plate 41 and the corresponding baffle 43 abut against each other, each filter area is blocked by the cover plate 41.

[0044] This design allows the connecting strip 42 to move synchronously with multiple cover plates 41. By moving the cover plate 41 to abut against the corresponding baffle 43, the dust adhering to the filter area is placed in the groove area of ​​the cover plate 41. Because it is blocked by the cover plate 41, the dust is prevented from drifting into the surrounding environment when the filter screen 3 is removed. After reaching the cleaning location, the cover plate 41 can be moved in the opposite direction to remove the cover plate 41 from blocking the filter area without affecting the normal cleaning operation.

[0045] In one embodiment, a locking component 8 for locking the connecting strip 42 is provided on the connecting strip 42. The locking component 8 includes a movable strip 81 disposed on the air inlet side of the filter screen 3 and connected to one end of the connecting strip 42. The movable strip 81 is located outside the moving area of ​​the cover plate 41. At least one tension spring 82 is provided between the movable strip 81 and the outermost stop strip 43. When the tension spring 82 is in its natural state, the filter area is not blocked by the cover plate 41. A first pin seat 83 is provided on the side of the movable strip 81 away from the stop strip 43. The locking assembly 8 is provided with a positioning pin 84 that can move up and down and pass through the first pin seat 83. The locking assembly 8 also includes a second pin seat 85 located on the air inlet side of the filter screen 3 and a top pusher 86 located on the corresponding positioning plate 7. The second pin seat 85 is provided with a hole for the positioning pin 84 to be inserted. When the positioning pin 84 passes through the first pin seat 83 and is inserted into the second pin seat 85, the filter area is blocked by the cover plate 41. When the filter screen 3 moves to the lower limit position of the slide, the top pusher 86 passes through the hole and is flush with the top of the second pin seat 85.

[0046] This design ensures that after the filter screen 3 is installed on the positioning plate 7, the top pusher 86 occupies the insertion hole of the second pin seat 85, preventing the positioning pin 84 from being inserted. At this time, under the action of the tension spring 82, the filtration area will not be blocked by the cover plate 41, and the filtration operation can be carried out normally. When the filter screen 3 is removed from the positioning plate 7, the top pusher 86 moves out of the insertion hole, allowing the positioning pin 84 to be inserted into the insertion hole. This ensures that the cover plate 41, which blocks the filtration area, can remain in the corresponding position for a long time, further improving stability.

[0047] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0048] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
