The filters intercept dust, fibers, and other pollutants in the air, ensuring that the air entering the metering cabinet body is clean and achieving a good dustproof effect.

Description

Technical Field

[0001] This utility model relates to the field of high-voltage metering cabinet technology, specifically a closed high-voltage metering cabinet. Background Technology

[0002] Enclosed high-voltage metering cabinets play an important role in power systems, providing accurate electricity metering, ensuring the safety and reliability of the power system, and controlling its operation.

[0003] The utility model patent application with publication number "CN216390115U" discloses a high-voltage metering cabinet, which mainly consists of a cabinet body, a moisture-proof mat, a reset mechanism, a shielding mechanism, a support mechanism, and a closing mechanism. This technical solution, through the cooperation between the moisture-proof mat and the cabinet body, ensures that the cabinet body does not come into contact with the ground, thereby reducing the corrosion of the bottom surface of the cabinet body by moisture. Through the cooperation between the shielding mechanism, the support mechanism, and the reset mechanism, the shielding mechanism can prevent heavy snow from falling on the cabinet body. At the same time, when there is a lot of snow accumulation on the shielding mechanism, the support mechanism and the reset mechanism can make the shielding mechanism swing, thereby causing the snow on the shielding mechanism to fall to the ground. This solves the problem of high-voltage metering cabinets accumulating a large amount of snow during heavy snow in Northeast China.

[0004] The high-voltage metering cabinet disclosed in the aforementioned document has the following defects: When the metering cabinet is in use, the high-voltage equipment (such as transformers, circuit breakers, metering instruments, etc.) inside the metering cabinet generates heat during operation. The continuous accumulation of heat leads to an increase in temperature, which can easily cause electronic components (such as capacitors, resistors, chips) to drift due to overheating, shortening their service life. In the existing technology, an exhaust fan is generally installed on the lower surface of the metering cabinet. By starting the exhaust fan, a suction force is generated inside the metering cabinet, allowing outside air to enter the interior of the metering cabinet through the heat dissipation holes on both sides of the metering cabinet, thereby dissipating heat from the high-voltage equipment inside the metering cabinet. However, when the exhaust fan is running, external impurities and particulate matter also enter the interior of the metering cabinet through the heat dissipation holes, and then adhere to the surface of the high-voltage equipment, affecting the heat dissipation effect of the high-voltage equipment. Utility Model Content

[0005] The purpose of this invention is to provide a closed high-voltage metering cabinet that solves the problem that in existing high-voltage metering cabinets, when the exhaust fan is running, external impurities and particulate matter enter the interior of the high-voltage metering cabinet through the heat dissipation holes, and then adhere to the surface of the high-voltage equipment, affecting the heat dissipation effect of the high-voltage equipment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a closed high-pressure metering cabinet, comprising a metering cabinet body, a cabinet door hinged to the front of the metering cabinet body, and openings at both ends of the metering cabinet body. Each of the two openings has a dustproof structure inside, the dustproof structure comprising an outer shell, a connecting shaft installed inside the opening, one end of the outer shell hinged to the outer surface of the connecting shaft, several air inlets at one end of the outer shell, several exhaust holes at the other end of the outer shell, a mounting plate slidably connected inside the outer shell, several mounting holes on the outer surface of the mounting plate, and filters installed inside the mounting holes.

[0008] Furthermore, one end of the outer casing is provided with several protective plates, the number of which is the same as the number of air inlets. The other end of the outer casing is provided with a connecting block, and the upper surface of the connecting block is provided with fixing holes.

[0009] Furthermore, a connecting plate is installed on the outer surface of the metering cabinet body, and an installation hole is opened on the upper surface of the connecting plate. A slide rod is slidably connected inside the installation hole, and a fixing block is installed at the lower end of the slide rod. The fixing block is fitted inside the fixing hole. A spring is sleeved on the outer surface of the slide rod. One end of the spring is installed on the lower surface of the connecting plate, and the other end of the spring is installed on the upper surface of the fixing block.

[0010] Furthermore, the upper end of the slide bar is threaded with a pull block, and the lower surface of the pull block abuts against the upper surface of the connecting plate.

[0011] Furthermore, the lower surface of the metering cabinet body is provided with a mounting groove, the inner surface of the mounting groove is provided with a through groove, one end of the through groove extends into the interior of the metering cabinet body, an exhaust fan is installed inside the mounting groove, a support base is installed on the lower surface of the metering cabinet body, and a through hole is provided on the upper surface of the support base.

[0012] Furthermore, a sealing groove is provided on the outer surface of the metering cabinet body, and a sealing ring is provided on the outer surface of the cabinet door, with the sealing ring fitted inside the sealing groove.

[0013] This utility model has the following beneficial effects:

[0014] (1) By starting the exhaust fan, the metering cabinet body generates suction inside, which in turn causes outside air to come into contact with the protective plate on the outside of the air inlet of the outer shell. The inclined design of the protective plate guides the airflow to concentrate and enter the air inlet, while blocking large particles of debris from directly impacting the filter screen. After the air passes through the air inlet, it enters the interior of the outer shell and flows through the filter screen on the mounting plate. The filter screen intercepts pollutants such as dust and fibers in the air, ensuring that the air entering the metering cabinet body is clean and achieving a good dustproof effect.

[0015] (2) By pulling the pull block upward, the slide rod slides upward in the mounting hole, causing the fixing block to gradually disengage from the fixing hole of the connecting block. At the same time, the spring gradually contracts. When the fixing block is completely disengaged from the fixing hole, the outer shell hinged to the opening flips outward, causing it to tilt and thus exposing the mounting plate. Then, by pulling the mounting plate outward, the mounting plate and the filter screen are taken out from the outer shell together. The mounting plate adopts a drawer-type sliding structure, and the filter screen is directly embedded in the mounting hole. It can be cleaned directly after being pulled out, avoiding the problem of long-term dust accumulation on the filter screen due to cumbersome maintenance.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 As shown, this utility model is a closed high-pressure metering cabinet, including a metering cabinet body 1. A cabinet door 2 is hinged to the front of the metering cabinet body 1. Both ends of the metering cabinet body 1 are provided with openings 101. A dustproof structure 3 is provided inside the two openings 101. The dustproof structure 3 includes a shell 301. A connecting shaft is installed inside the opening 101. One end of the shell 301 is hinged to the outer surface of the connecting shaft. A plurality of air inlets 302 are provided at one end of the shell 301. A plurality of exhaust holes 303 are provided at the other end of the shell 301. A mounting plate 304 is slidably connected inside the shell 301. A plurality of mounting holes are provided on the outer surface of the mounting plate 304. A filter screen 305 is installed inside the mounting holes.

[0027] One end of the outer casing 301 is provided with several protective plates 306. The number of protective plates 306 and mounting holes are the same as the number of air inlets 302. The other end of the outer casing 301 is provided with a connecting block 307. The upper surface of the connecting block 307 is provided with fixing holes.

[0028] The lower surface of the metering cabinet body 1 is provided with a mounting groove 102, the inner surface of the mounting groove 102 is provided with a through groove, one end of the through groove extends into the interior of the metering cabinet body 1, an exhaust fan 4 is installed inside the mounting groove 102, a support base 5 is installed on the lower surface of the metering cabinet body 1, and a through hole is provided on the upper surface of the support base 5.

[0029] When in use, first place the metering cabinet body 1 in the place to be used. By turning on the exhaust fan 4, the inside of the metering cabinet body 1 will generate suction, which will cause the outside air to come into contact with the protective plate 306 on the outside of the air inlet 302 of the outer shell 301. The inclined design of the protective plate 306 guides the airflow to concentrate into the air inlet 302, while blocking large particles of debris from directly impacting the filter screen 305. After that, the air enters the inside of the outer shell 301 after passing through the air inlet 302, and flows through the filter screen 305 on the mounting plate 304. The filter screen 305 intercepts pollutants such as dust and fibers in the air, ensuring that the air entering the metering cabinet body 1 is clean. The hot air inside the metering cabinet body 1 is discharged to the outside through the through groove on the lower surface of the metering cabinet body 1 under the suction of the exhaust fan 4.

[0030] A connecting plate 308 is installed on the outer surface of the metering cabinet body 1. An installation hole is opened on the upper surface of the connecting plate 308. A slide rod 309 is slidably connected inside the installation hole. A fixing block 3010 is installed at the lower end of the slide rod 309. The fixing block 3010 is fitted inside the fixing hole. A spring 3011 is sleeved on the outer surface of the slide rod 309. One end of the spring 3011 is installed on the lower surface of the connecting plate 308, and the other end of the spring 3011 is installed on the upper surface of the fixing block 3010.

[0031] The upper end of the slide bar 309 is threadedly connected to a pull block 3012, and the lower surface of the pull block 3012 abuts against the upper surface of the connecting plate 308.

[0032] When the filter 305 needs cleaning, the cabinet door 2 is opened, and the pull block 3012 is pulled upwards, causing the slide rod 309 to slide upwards in the mounting hole. This causes the fixing block 3010 to gradually disengage from the fixing hole of the connecting block 307, while the spring 3011 gradually contracts. After the fixing block 3010 is completely disengaged from the fixing hole, the outer shell 301, which is hinged to the through-hole 101, is flipped outwards, causing it to tilt and exposing the mounting plate 304. Then, by pulling the mounting plate 304 outwards, the mounting plate 304 and the filter 305 are removed from the outer shell 301. The mounting plate 304 adopts a drawer-type sliding structure, and the filter 305 is directly embedded in the mounting hole. It can be cleaned directly after being pulled out, avoiding the problem of long-term dust accumulation on the filter 305 due to cumbersome maintenance.

[0033] A sealing groove 103 is provided on the outer surface of the metering cabinet body 1, and a sealing ring 201 is provided on the outer surface of the cabinet door 2. The sealing ring 201 is installed in the sealing groove 103.

[0034] By using the sealing groove 103 in conjunction with the sealing ring 201, the iron piece can be prevented from being inserted into the gap, thus avoiding the cabinet door 2 from being pried open and achieving a better anti-theft effect.
