Description
Technical Field
[0001] This utility model relates to the field of power distribution cabinet protection technology, and in particular to a power distribution cabinet with protective function. Background Technology
[0002] A distribution cabinet is an electrical device used for centralized management and distribution of electrical energy. It is widely used in various power-consuming locations such as factories, buildings, substations, and industrial parks. Its main function is to convert or distribute high-voltage or medium-voltage electrical energy to various low-voltage circuits to ensure safe, stable, and efficient power supply. To ensure the normal and safe operation of its internal electronic components and electrical equipment, dust filters need to be installed at the air inlet and outlet of the distribution cabinet to prevent dust and impurities from entering the cabinet. However, most distribution cabinets in the current technology still have problems that need to be solved.
[0003] In the existing technology, most dust filters on power distribution cabinets are fixed to the outer wall of the cabinet with screws. Every time the dust filter needs to be cleaned or replaced, the screws need to be removed, which is cumbersome. Especially in environments with dense equipment or limited space, this increases the difficulty and workload of maintenance and is very inconvenient. Therefore, it is necessary to design a power distribution cabinet with protective functions to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a power distribution cabinet with protective functions.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A protective distribution cabinet includes a cabinet with air inlets at the bottom of both sides and an exhaust port at the top of the back. A support plate is provided at both the air inlets and exhaust port. U-shaped plates are fixedly connected to the top of both ends of the support plate. A common frame is provided within the two U-shaped plates, and a filter screen is installed on the frame. A rubber sealing gasket is fixedly connected to the frame on the side closest to the distribution cabinet. A first loop-shaped frame plate is provided on one side of the U-shaped plate and is fixedly connected to the outer wall of the distribution cabinet. A limit plate is provided at the bottom of the first loop-shaped frame plate, and the limit plate is fixedly connected to the U-shaped plate. A second loop-shaped frame plate passes through the limit plate and is slidably connected to the limit plate. A square plate is fixedly connected to the second loop-shaped frame plate on the side away from the distribution cabinet. Two pins are fixedly connected to the square plate on the side closest to the distribution cabinet at the end away from the second loop-shaped frame plate. Two slots are provided at both ends of the frame, and the slots are adapted to the pins. The limiting plate contains an insert plate that is compatible with the first loop frame plate. Due to the use of a quick-release mechanism for installing and removing the filter, the filter effectively prevents impurities from entering the distribution cabinet, protecting the internal electrical equipment. When installing the filter, the insert plate is placed inside the first loop frame plate and the limiting plate, ensuring the rubber sealing gasket is tightly against the distribution cabinet and the pin is inserted into the slot. The filter is then installed. Removing the insert plate allows for easy removal of the filter. This effectively solves the problem mentioned in the background art where dust filters on most existing distribution cabinets are fixed to the outer wall of the distribution cabinet with screws. Each time the dust filter needs to be cleaned or replaced, the screws need to be removed, which is cumbersome, especially in environments with dense equipment or limited space, increasing maintenance difficulty and workload. This solution greatly simplifies installation and disassembly steps, improves the convenience of filter replacement, significantly shortens equipment maintenance and cleaning time, reduces downtime, and improves work efficiency.
[0006] As a further embodiment of this utility model, a magnet is fixedly connected to the bottom inner wall of the limiting plate, and the insert plate is made of metal.
[0007] As a further embodiment of this utility model, the limiting plate is fixedly connected to two first sleeve plates on the side away from the U-shaped plate, the first sleeve plates are provided with a first limiting plate, the first limiting plate is slidably connected to the first sleeve plates, the first limiting plate is fixedly connected to the power distribution cabinet, and the first limiting plate is fixedly connected to a first baffle on the side away from the power distribution cabinet.
[0008] As a further embodiment of this utility model, the limiting plate is fixedly connected to two second sleeve plates on the side away from the U-shaped plate, and a second limiting rod is provided through the second sleeve plate. The second limiting rod is slidably connected to the second sleeve plate, and a second baffle is fixedly connected to the second limiting rod on the side close to the power distribution cabinet.
[0009] As a further embodiment of this utility model, the second limiting rod is fixedly connected to a connecting plate on the side away from the power distribution cabinet, and both connecting plates at the same end are fixedly connected to a square plate.
[0010] As a further embodiment of this utility model, the U-shaped plate is provided with a circular groove that matches the pin.
[0011] The beneficial effects of this utility model are as follows: By employing a quick-release mechanism for installing and removing the filter, the filter effectively prevents impurities from entering the distribution cabinet, protecting the internal electrical equipment. During installation, the insert plate is placed inside the first rectangular frame and the limiting plate, ensuring the rubber sealing gasket is flush against the distribution cabinet and allowing the pin to be inserted into the slot. The filter is then installed by removing the insert plate. This effectively solves the problem mentioned in the background section where existing distribution cabinet dust filters are typically fixed to the outer wall with screws. Each time the dust filter needs cleaning or replacement, the screws must be removed, which is cumbersome, especially in environments with dense equipment or limited space, increasing maintenance difficulty and workload. This significantly simplifies installation and removal steps, improves the convenience of filter replacement, greatly shortens equipment maintenance and cleaning time, reduces downtime, and improves work efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Reference Figure 1-7A protective distribution cabinet includes a distribution cabinet 1. Air inlets 2 are located at the bottom of both sides of the distribution cabinet 1, and an exhaust port 3 is located at the top of the back of the distribution cabinet 1. Support plates 4 are installed at both the air inlets 2 and the exhaust port 3. U-shaped plates 5 are fixedly connected to the top of both ends of the support plates 4. A common frame 6 is installed within the two U-shaped plates 5. A filter screen 7 is installed on the frame 6. A rubber sealing gasket 8 is fixedly connected to the side of the frame 6 closest to the distribution cabinet 1. A first U-shaped frame plate 9 is installed on one side of the U-shaped plate 5. The first U-shaped frame plate 9 is fixedly connected to the outer wall of the distribution cabinet 1. A limit plate 10 is provided at the bottom of the first U-shaped frame plate 9. The limit plate 10 is fixedly connected to the U-shaped plate 5. A second U-shaped frame plate 11 passes through the limit plate 10. The second U-shaped frame plate 11 is slidably connected to the limit plate 10. A square plate 12 is fixedly connected to the side of the second U-shaped frame plate 11 away from the distribution cabinet 1. Two pins 13 are fixedly connected to the end of the square plate 12 away from the second U-shaped frame plate 11 and the side closer to the distribution cabinet 1. Two slots 24 are provided at both ends of the frame 6. 24 is compatible with pin 13. A plug plate 14 is provided inside the limiting plate 10. The plug plate 14 is compatible with the first loop frame plate 9. Due to the use of a quick-release mechanism for installing and removing the filter screen, the filter screen can effectively prevent impurities from entering the inside of the distribution cabinet and protect the electrical equipment inside the distribution cabinet. When installing the filter screen, the plug plate is placed inside the first loop frame plate and the limiting plate, so that the rubber sealing gasket is tightly attached to the distribution cabinet and the pin is inserted into the slot. The filter screen can then be installed. The plug plate can be removed to remove the filter screen. This effectively solves the problem mentioned in the background art that in most existing distribution cabinets, the dust screen is usually fixed to the outer wall of the distribution cabinet by screws. Every time the dust screen needs to be cleaned or replaced, the screws need to be removed, which is cumbersome. Especially in environments with dense equipment or limited space, this increases the difficulty and workload of maintenance and is very inconvenient. This technology greatly simplifies the installation and disassembly steps, improves the convenience of replacing the filter screen, greatly shortens the equipment maintenance and cleaning time, reduces downtime, and improves work efficiency.
[0016] In this embodiment, a magnet 15 is fixedly connected to the bottom inner wall of the limiting plate 10, and the insert plate 14 is made of metal. The magnet 15 attracts the insert plate 14, so that the insert plate 14 can be stably placed inside the first loop frame plate 9 and the limiting plate 10.
[0017] In this embodiment, the limiting plate 10 is fixedly connected to two first sleeve plates 16 on the side away from the U-shaped plate 5. A first limiting plate 17 is provided on the first sleeve plate 16. The first limiting plate 17 is slidably connected to the first sleeve plate 16. The first limiting plate 17 is fixedly connected to the power distribution cabinet 1. A first baffle 18 is fixedly connected to the first limiting plate 17 on the side away from the power distribution cabinet 1. When the limiting plate 10 is moved, the limiting plate 10 will drive the first sleeve plate 16 to move along the first limiting plate 17, ensuring the stability of the limiting plate 10 when it moves.
[0018] In this embodiment, the limiting plate 10 is fixedly connected to two second sleeve plates 21 on the side away from the U-shaped plate 5. A second limiting rod 19 is provided on the second sleeve plate 21. The second limiting rod 19 is slidably connected to the second sleeve plate 21. A second baffle 20 is fixedly connected to the second limiting rod 19 on the side close to the power distribution cabinet 1.
[0019] In this embodiment, the second limiting rod 19 is fixedly connected to a connecting plate 23 on the side away from the power distribution cabinet 1, and the two connecting plates 23 at the same end are both fixedly connected to a square plate 12.
[0020] In this embodiment, the U-shaped plate 5 has a circular groove 22 that matches the pin 13. When the pin 13 is inserted into the slot 24, the pin 13 passes through the circular groove 22, which can restrict the frame 6 and the U-shaped plate 5 and ensure the positional stability between the U-shaped plate 5 and the frame 6.
[0021] Working principle: During use, filter 7 effectively filters impurities in the air, preventing them from being sucked into the distribution cabinet 1 and affecting the operation of the internal equipment, thus effectively protecting the electrical equipment inside the distribution cabinet 1. When filter 7 needs to be removed for deep maintenance, the insert plate 14 is removed from the first loop frame plate 9 and the limiting plate 10, which releases the restriction on the second loop frame plate 11 and the limiting plate 10. The square plate 12 can be moved, which will cause the pin 13 to move and be removed from the slot 24, thus releasing the frame. The frame 6 and the U-shaped plate 5 are restricted, allowing the frame 6 to be removed from the U-shaped plate 5. This enables a deep cleaning of the filter screen 7, removing impurities from its surface and ensuring its breathability, thus guaranteeing heat dissipation. During assembly, the frame 6 is inserted into the two U-shaped plates 5, and then the insert plate 14 is inserted into the first U-shaped frame plate 9. As the insert plate 14 descends, its inclined surface contacts the limiting plate 10. Continuing to descend the insert plate 14, it presses against the limiting plate 10, causing the limiting plate 10 to move closer to the distribution cabinet 1. The limiting plate 10 then drives the second U-shaped frame plate 9 to move closer to the distribution cabinet 1. A set of plates 16 moves along the first limiting plate 17 to ensure the stability of the limiting plate 10 during movement. The movement of the limiting plate 10 also drives the U-shaped plate 5 to move, which in turn drives the frame 6 to move closer to the distribution cabinet 1. The movement of the frame 6 drives the rubber sealing gasket 8 to move, so that the rubber sealing gasket 8 contacts the distribution cabinet 1. The rubber sealing gasket 8 deforms to fit tightly against the distribution cabinet 1, ensuring airtightness and preventing impurities from entering the distribution cabinet 1. This causes the plug plate 14 to continue descending, and the inclined surface of the plug plate 14 will contact the second loop-shaped frame plate 11. The continued descent of the plug plate 14 will drive the second loop-shaped frame plate 11 to move closer to the distribution cabinet 11. When frame plate 11 moves closer to distribution cabinet 1, the second U-shaped frame plate 11 will drive the square plate 12 to move, and the square plate 12 will drive the pin 13 to move into slot 24, which can restrict the position between U-shaped plate 5 and frame 6, ensuring the stability of frame 6, and thus ensuring the stability of filter screen 7. When square plate 12 moves, it will drive connecting plate 23 to move, and connecting plate 23 will drive the second limit rod 19 to move along the second set plate 21, ensuring the stability of square plate 12 when it moves, and thus ensuring the stability of pin 13 when it moves.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
