Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a high-voltage power distribution cabinet that is easy to test. Background Technology

[0002] High-voltage intelligent distribution cabinets, also known as precision distribution cabinets, are designed for the energy end of data center computer rooms. They comprehensively collect all energy data to provide high-precision measurement data for terminal energy monitoring systems. Through display units, they reflect power quality data in real time. They are used in power systems for power generation, transmission, distribution, power conversion, and consumption, playing roles such as switching, control, or protection. These electrical products have voltage levels ranging from 3.6kV to 550kV and mainly include several categories such as high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear. Publication No. CN206976831U discloses a high-voltage distribution cabinet, which includes a cabinet body, a top cover at the top of the cabinet body, and a bottom plate at the bottom of the cabinet body. The cabinet body houses a temperature controller connected to a fan, which in turn is connected to a power supply. The fan is connected to a heat dissipation channel. The cabinet body also includes an air inlet with an air intake device. The air intake device includes a through-hole on the side wall of the cabinet body, which extends to an air intake hood located outside the cabinet body. By configuring the air inlet in the form of an air intake hood, an extension, and a through-hole, the volume of incoming air can be instantly reduced. Thus, while maintaining constant pressure, the temperature decreases accordingly. In other words, the temperature entering the cabinet is lower than the temperature outside the cabinet body, which is more conducive to cooling the components inside the cabinet. This effective cooling protects the normal operation of the equipment and ensures the city's water supply. However, in the process of using the above technologies, the dustproof device is set inside the through hole. Over time, a large amount of dust and lint will adhere to the surface of the dustproof device. Because the dustproof device is located inside the through hole, it is difficult to clean the dust and lint on the surface of the dustproof device, and it cannot be cleaned effectively. This makes the dustproof device inconvenient to clean and inefficient. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a high-voltage distribution cabinet for easy testing, comprising a cabinet body, a cabinet door rotatably connected to the surface of the cabinet body, a first fixing plate and a second fixing plate fixedly connected to the bottom surface of the cabinet body, a lead screw rotatably connected between the second fixing plate and the first fixing plate, a drive block threadedly connected to the surface of the lead screw, an mounting plate fixedly connected to the surface of the drive block, an air inlet and a heat dissipation channel opened on the surface of the cabinet body, a dustproof plate provided at the air inlet, a square block fixedly connected to the surface of the dustproof plate, a fixing block fixedly connected to the surface of the cabinet body, the square block engaging with the fixing block, a sliding groove opened on the surface of the square block, a locking block slidably connected inside the sliding groove, a spring provided inside the sliding groove, the spring fixedly connected to the locking block, a handle fixedly connected to the surface of the locking block, and an exhaust assembly provided at the heat dissipation channel.

[0005] Preferably, the exhaust assembly includes a square plate, on the surface of which a second motor is fixedly connected, and a fan blade is fixedly connected to the output end of the motor. This accelerates airflow within the cabinet, allowing heat generated by electronic components mounted on the cabinet mounting plate to be quickly dissipated through the heat dissipation channel, thus accelerating heat dissipation.

[0006] Preferably, the surface of the fixing block has a slot, which aligns with the opening of the sliding groove. This facilitates the insertion of the fixing block into the slot, achieving the purpose of quickly fixing the dustproof plate.

[0007] Preferably, there are two sets of locking blocks, which are symmetrically distributed on both sides of the center of the dustproof panel surface. This improves the stability of the connection between the dustproof panel and the cabinet, making the connection more secure.

[0008] Preferably, a handle is fixedly connected to the surface of the dustproof panel, and the handle is located between the two sets of blocks. Here, the ease of assembling and disassembling the dustproof panel can be further improved by holding the handle.

[0009] Preferably, a motor is fixedly connected to the surface of the first fixing plate, and the output end of the motor is fixedly connected to a lead screw. Here, the motor can drive the lead screw to rotate, making it easier to move the mounting plate to the opening of the cabinet, thus making it more convenient for staff to test the electrical components on the mounting plate.

[0010] Preferably, a rod is fixedly connected to the surface of the dustproof panel, and a slot is provided on the surface of the cabinet. A magnet is fixedly connected inside the slot, and the magnet is attracted to the rod. A sealing gasket is fixedly connected to the surface of the dustproof panel, and the sealing gasket is located between the surfaces of the dustproof panel and the cabinet. This design allows the four corners of the dustproof panel to fit more snugly against the cabinet, preventing warping, and also improves the seal between the dustproof panel and the cabinet, preventing dust and airborne particles from entering or leaving the cabinet through gaps between the dustproof panel and the cabinet surface.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model incorporates a fixing block, a square block, a locking block, a spring, and a handle. During use, air enters the cabinet after being filtered and purified by the dustproof plate. When the dustproof plate needs to be disassembled and cleaned, pushing the handle causes the locking block to slide inside the square block and compress the spring. Then, the handle on the dustproof plate can be grasped to remove it from the cabinet for cleaning. This design secures the dustproof plate to the cabinet and facilitates its disassembly and cleaning, preventing the pores from becoming clogged due to prolonged use, which would impede airflow and thus heat dissipation.

[0013] 2. This utility model incorporates a structure of insert rods, magnets, and sealing gaskets. When the dustproof panel is installed on the cabinet, the sealing gaskets on the dustproof panel are tightly pressed against the surface of the cabinet, and the insert rods on the dustproof panel are inserted into the slots on the cabinet and magnetically attracted to the magnets. This allows the four corners of the dustproof panel to fit more snugly against the cabinet, preventing warping. It also improves the sealing between the dustproof panel and the cabinet, preventing dust and airborne particles from entering or leaving the interior of the cabinet through the gaps between the dustproof panel and the cabinet surface.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-6This utility model provides a technical solution: a high-voltage distribution cabinet for easy testing, comprising a cabinet body 1, a cabinet door 2 rotatably connected to the surface of the cabinet body 1, a first fixing plate 3 and a second fixing plate 4 fixedly connected to the bottom surface of the cabinet body 1, a lead screw 5 rotatably connected between the second fixing plate 4 and the first fixing plate 3, a drive block 6 threadedly connected to the surface of the lead screw 5, an mounting plate 7 fixedly connected to the surface of the drive block 6, an air inlet 9 and a heat dissipation channel 10 on the surface of the cabinet body 1, a dustproof plate 11 provided at the air inlet 9, a square block 13 fixedly connected to the surface of the dustproof plate 11, a fixing block 12 fixedly connected to the surface of the cabinet body 1, the square block 13 engaging with the fixing block 12, a sliding groove 17 on the surface of the square block 13, a locking block 18 slidably connected inside the sliding groove 17, a spring 20 provided inside the sliding groove 17, the spring 20 fixedly connected to the locking block 18, a handle 19 fixedly connected to the surface of the locking block 18, and an exhaust assembly provided at the heat dissipation channel. The exhaust assembly includes a square plate 24, on which a motor 25 is fixedly connected. A fan blade 26 is fixedly connected to the output end of the motor. This accelerates the air circulation inside the cabinet 1, allowing the heat generated by the electronic components installed on the mounting plate 7 inside the cabinet 1 to be quickly dissipated through the heat dissipation channel, thus accelerating heat dissipation. A slot 14 is provided on the surface of the fixing block 12, which is aligned with the groove of the slide 17. This facilitates the insertion of the locking block 18 into the slot 14, achieving the purpose of quickly fixing the dustproof plate 11. There are two sets of locking blocks 18, which are symmetrically distributed on both sides of the middle of the surface of the dustproof plate 11. This improves the stability of the connection between the dustproof plate 11 and the cabinet 1, making the connection between the dustproof plate 11 and the cabinet 1 more secure. A handle 23 is fixedly connected to the surface of the dustproof plate 11, located between the two sets of square blocks 13. This allows for further improvement in the ease of disassembling and assembling the dustproof plate 11 by gripping the handle 23.

[0026] Example 2

[0027] Please see Figure 4-6 A motor 8 is fixedly connected to the surface of the first fixed plate 3. The output end of the motor 8 is fixedly connected to the lead screw 5. The motor 8 can drive the lead screw 5 to rotate, making it easier to move the mounting plate 7 to the opening of the cabinet 1. This makes it more convenient for staff to test the electrical components on the mounting plate 7. A plug rod 21 is fixedly connected to the surface of the dustproof plate 11. A slot 15 is opened on the surface of the cabinet 1. A magnet 16 is fixedly connected inside the slot 15. The magnet 16 is attracted to the plug rod 21. A sealing gasket 22 is fixedly connected to the surface of the dustproof plate 11. The sealing gasket 22 is located between the surface of the dustproof plate 11 and the surface of the cabinet 1. This allows the four corners of the dustproof plate 11 to fit more closely to the cabinet 1, preventing warping. At the same time, it can improve the sealing between the dustproof plate 11 and the cabinet 1, preventing dust and airborne particles from entering or leaving the interior of the cabinet 1 through the gap between the dustproof plate 11 and the surface of the cabinet 1.

[0028] Working Principle: During use, the electrical components on mounting plate 7 generate a large amount of heat, activating motor 25. The output of motor 25 drives fan blade 26 to rotate and generate suction. Cold air from the outside enters the cabinet 1 after being filtered and purified by the dustproof plate 11 on one side of air inlet 9. The heat inside the cabinet 1 is blown to the outside through the heat dissipation channel 10 by the fan blade 26. When it is necessary to disassemble and clean the dustproof plate 11, push the handle 19. The locking block 18 is pressed and slides inside the sliding groove 17 on the block 13, compressing the spring 20. The locking block 18 disengages from the locking groove 14 on the fixing block 12. Then, grasp the handle 23 on the dustproof plate 11 to remove the dustproof plate 11 from the cabinet 1 for cleaning. This fixes the dustproof plate 11 to the cabinet 1 and facilitates the disassembly and cleaning of the dustproof plate 11 later. This prevents the pores of the dustproof plate 11 from becoming clogged due to prolonged use, which would affect air circulation. This can affect heat dissipation. When the dustproof plate 11 is installed on the cabinet 1, the sealing gasket 22 on the dustproof plate 11 is tightly attached to the surface of the cabinet 1, and the insertion rod 21 on the dustproof plate 11 is inserted into the slot 15 on the cabinet 1 and magnetically attracted to the magnet 16. This allows the four corners of the dustproof plate 11 to fit more closely to the cabinet 1, avoiding warping. At the same time, it can improve the sealing between the dustproof plate 11 and the cabinet 1, preventing dust and airborne particles from entering or leaving the interior of the cabinet 1 through the gap between the dustproof plate 11 and the surface of the cabinet 1. When it is necessary to inspect, maintain or repair the electrical components on the mounting plate 7, open the cabinet door 2, and then start the motor 8. The output end of the motor 8 drives the lead screw 5 between the first fixed plate 3 and the second fixed plate 4 to rotate. As the lead screw 5 rotates, it drives the drive block 6 and the mounting plate 7 to move. The mounting plate 7 slowly moves to the opening of the cabinet 1, and then the staff can inspect, maintain or repair the electrical components installed on the mounting plate 7.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
