Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to a ventilation and heat dissipation device for power distribution cabinets. Background Technology

[0002] Distribution cabinets are the final-level equipment in a power distribution system, used to distribute, control, meter, and protect electrical energy. They contain components such as circuit breakers, disconnect switches, and contactors. Classified by application, they include power cabinets and lighting cabinets. They distribute power from the upper level to various branches, monitor circuit status, and automatically cut off power in case of faults. Widely used in factories, buildings, and residential buildings, they are key equipment for the safe operation of power systems. Ventilation and heat dissipation devices in distribution cabinets are crucial. Electrical components inside the cabinet generate heat during operation; high temperatures accelerate insulation aging, reduce component performance, and can even cause short circuits and fires. Heat dissipation devices can promptly remove heat, maintain a suitable temperature, ensure stable equipment operation, extend service life, and prevent power failures caused by overheating. They are a key link in ensuring the safety and reliability of the power distribution system.

[0003] After prolonged use, the filter plates of common power distribution cabinet ventilation and heat dissipation devices accumulate a lot of dust. Workers need to remove the filter plates from the device and clean and replace them. Since the filter plates are usually fixed by multiple bolts, workers need to use professional tools to disassemble them, which is a tedious, time-consuming and labor-intensive process.

The clamping grooves are located on the left and right sides of the filter plate. The clamping element is attached to the inner wall of the clamping groove on the opposite side, and a spring-loaded assembly is provided on the opposite side of the clamping element.

[0006] As a preferred embodiment of this utility model, two rebound components are provided. The two rebound components include a connecting block, a tension spring, and a support plate. The connecting block is fixedly connected to the opposite side of the clamping member on one side. The tension spring is sleeved on the outer surface of the connecting block. The support plate is fixedly connected to the opposite side of the tension spring and the connecting block on one side.

[0007] As a preferred embodiment of this utility model, the outer surface of the connecting block is provided with a limiting plate, and three limiting plates are provided. The lower surfaces of the three limiting plates are fixedly connected to the upper surface of the ventilation housing, and the inner wall of the limiting plate is slidably connected to the outer surface of the connecting block.

[0008] As a preferred embodiment of the present invention, a pressing assembly is provided on the front side of the connecting block. The pressing assembly includes a pressing roller and a connecting rod. Two pressing rollers are provided, and the outer surfaces of the two pressing rollers are in contact with the upper surface of the clamping member. The left and right ends of the connecting rod are rotatably connected to the inner wall of the pressing rollers through bearings.

[0009] In a preferred embodiment of this invention, a sliding assembly is provided on the rear side of the connecting rod. Three sliding assemblies are provided, each comprising a connecting post, a sliding plate, a spring, and a first sliding groove. The front end face of the connecting post is fixedly connected to the outer surface of the connecting rod. The front surface of the sliding plate is fixedly connected to the rear end face of the connecting post. The upper end face of the tension spring is fixedly connected to the lower surface of the sliding plate.

[0010] As a preferred embodiment of the present invention, a pressing assembly is provided on the front side of the connecting rod. The pressing assembly includes a pressing plate and a force-bearing plate. The rear surface of the pressing plate is fixedly connected to the outer surface of the connecting rod, and the rear surface of the force-bearing plate is fixedly connected to the front surface of the filter plate.

[0011] As a preferred embodiment of this utility model, the inner wall of the ventilation housing is provided with a second sliding groove, and there are two second sliding grooves. The inner walls of the two second sliding grooves are slidably connected to the left and right sides of the filter plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem that filter plates are usually fixed by multiple bolts, which requires workers to use professional tools to disassemble them, a process that is cumbersome, time-consuming and labor-intensive. When the filter plate is inserted, the lower surface automatically squeezes the inclined surface of the clamping part, driving the clamping part to move and accurately enter the clamping groove.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] 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. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a ventilation and heat dissipation device for a power distribution cabinet, including a cabinet body 1, a ventilation shell 2, a filter plate 3 and a cooling fan 4. The rear surface of the ventilation shell 2 is fixedly connected to the front surface of the cabinet body 1, the filter plate 3 is disposed inside the ventilation shell 2, the outer surface of the cooling fan 4 is fixedly connected to the inner wall of the ventilation shell 2, and a clamping mechanism 5 is provided on the outer surface of the filter plate 3. There are two clamping mechanisms 5. The two clamping mechanisms 5 include clamping grooves 51, clamping parts 52 and spring-loaded components 53. The clamping grooves 51 are opened on the left and right sides of the filter plate 3. The clamping parts 52 are in contact with the inner wall of the clamping grooves 51 on the opposite side. The spring-loaded components 53 are provided on the opposite side of the clamping parts 52.

[0022] Specifically, when the filter plate 3 is inserted, the lower surface automatically presses against the inclined surface of the clamping member 52, driving the clamping member 52 to move and accurately enter the clamping groove 51. No manual adjustment or tool assistance is required, and no additional fasteners such as screws or bolts are needed. Fixing is achieved solely through the cooperation between the clamping member 52 and the clamping groove 51, simplifying the structural complexity and significantly shortening the installation time.

[0023] Furthermore, by inserting the filter plate 3 into the ventilation housing 2, the lower surface of the filter plate 3 presses against the inclined surface of the clamping member 52, causing the clamping member 52 to move to the opposite side until the clamping grooves 51 on the left and right sides of the filter plate 3 correspond to the clamping member 52, so that the clamping member 52 can enter the clamping groove 51 and fix the filter plate 3 inside the ventilation housing 2.

[0024] Example 2 The second embodiment of this utility model provides a ventilation and heat dissipation device for a power distribution cabinet. Two spring-loaded components 53 are provided. The two spring-loaded components 53 include a connecting block 531, a tension spring 532 and a support plate 533. The connecting block 531 is fixedly connected to the opposite side of the clamping member 52 on one side. The tension spring 532 is sleeved on the outer surface of the connecting block 531. The support plate 533 is fixedly connected to the opposite side of the tension spring 532 and the connecting block 531 on one side. The outer surface of the connecting block 531 is provided with a limiting plate 6. There are three limiting plates 6. The lower surfaces of the three limiting plates 6 are fixedly connected to the upper surface of the ventilation housing 2. The inner wall of the limiting plate 6 is slidably connected to the outer surface of the connecting block 531.

[0025] Specifically, the tension spring 532 stores elastic potential energy when the clamping member 52 moves. When the clamping member 52 is aligned with the clamping groove 51, it releases energy and pulls the clamping member 52 into the groove automatically. This process does not require manual assistance and achieves "one-step" installation.

[0026] Furthermore, when the clamping member 52 moves to the opposite side, the clamping member 52 can push the connecting block 531, causing the connecting block 531 to push the support plate 533. The support plate 533 then pulls the tension spring 532, causing the tension spring 532 to generate tension. When the clamping member 52 corresponds to the clamping groove 51, the tension spring 532 releases the tension, pulling the clamping member 52 into the clamping groove 51.

[0027] Example 3 The third embodiment of this utility model provides a ventilation and heat dissipation device for a power distribution cabinet. A pressing component 7 is provided on the front side of the connecting block 531. The pressing component 7 includes a pressing roller 71 and a connecting rod 72. There are two pressing rollers 71. The outer surfaces of the two pressing rollers 71 are in contact with the upper surface of the clamping member 52. The left and right ends of the connecting rod 72 are rotatably connected to the inner wall of the pressing roller 71 through bearings. A sliding assembly 8 is provided on the rear side of the connecting rod 72. There are three sliding assemblies 8, each including a connecting post 81, a sliding plate 82, a spring 83, and a first sliding groove 84. The front end face of the connecting post 81 is fixedly connected to the outer surface of the connecting rod 72. The front surface of the sliding plate 82 is fixedly connected to the rear end face of the connecting post 81. The upper end face of the tension spring 532 is fixedly connected to the lower surface of the sliding plate 82. The first sliding groove 84 is opened on the front surface of the filter plate 3. The inner wall of the first sliding groove 84 is slidably connected to the outer surface of the sliding plate 82. The inner wall of the first sliding groove 84 is fixedly connected to the lower end face of the spring 83. A pressing component 9 is provided on the front side of the connecting rod 72. The pressing component 9 includes a pressing plate 91 and a force plate 92. The rear surface of the pressing plate 91 is fixedly connected to the outer surface of the connecting rod 72, and the rear surface of the force plate 92 is fixedly connected to the front surface of the filter plate 3. The inner wall of the ventilation housing 2 is provided with a second sliding groove 10. There are two second sliding grooves 10, and the inner walls of the two second sliding grooves 10 are slidably connected to the left and right sides of the filter plate 3.

[0028] Specifically, simply pinching the pressing component 9 can drive the squeezing roller 71 to squeeze the clamping member 52, causing the clamping member 52 to leave the clamping groove 51, thus efficiently unlocking and removing the filter plate 3.

[0029] Furthermore, by pinching the pressing component 9, the pressing plate 91 moves downward. The pressing plate 91 can drive the connecting column 81 via the connecting rod 72. The connecting column 81 then drives the sliding plate 82 to move downward along the inner wall of the first sliding groove 84, causing the sliding plate 82 to squeeze the spring 83. The spring 83 generates elastic force. At the same time, the connecting rod 72 can drive the rear pressing roller 71 to move downward together. The pressing roller 71 squeezes the inclined surface of the clamping member 52, causing the clamping member 52 to move to the opposite side until the clamping member 52 is no longer in contact with the clamping groove 51, at which point the filter plate 3 can be removed.

[0030] Working principle: By inserting the filter plate 3 into the ventilation housing 2 along the inner wall of the second slide groove 10, the lower surface of the filter plate 3 presses against the inclined surface of the clamping member 52, causing the clamping member 52 to move to the opposite side. The clamping member 52 can push the connecting block 531, causing the connecting block 531 to push the support plate 533. The support plate 533 then pulls the tension spring 532, causing the tension spring 532 to generate tension. When the clamping member 52 corresponds to the clamping groove 51, the tension spring 532 releases the tension, pulling the clamping member 52 into the clamping groove 51, thus fixing the filter plate 3 inside the ventilation housing 2. When the filter plate 3 needs to be replaced, the pressing assembly 9 is squeezed to move the pressing plate 91 downward. The pressing plate 91 can drive the connecting column 81 through the connecting rod 72. The connecting column 81 then drives the sliding plate 82 to move downward along the inner wall of the first sliding groove 84, so that the sliding plate 82 squeezes the spring 83. The spring 83 generates elastic force. At the same time, the connecting rod 72 can drive the rear pressing roller 71 to move downward together. The pressing roller 71 squeezes the inclined surface of the clamping member 52, so that the clamping member 52 moves to the opposite side until the clamping member 52 is no longer in contact with the clamping groove 51, and then the filter plate 3 can be removed.

[0031] In summary, the combination of clamping mechanism 5, limiting plate 6, squeezing component 7, sliding component 8, pressing component 9, and second slide groove 10 solves the problem that filter plates are usually fixed by multiple bolts, which requires workers to use professional tools to disassemble them, a process that is cumbersome, time-consuming, and labor-intensive.
