Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box with good ventilation effect. Background Art

[0002] In the modern power supply system, the distribution box, as the core equipment for power distribution and control, is of great importance. However, existing distribution boxes face many challenges in practical application.

[0003] The ventilation design of traditional distribution boxes is generally simple and difficult to meet actual needs. Inside the distribution box, many electrical devices will continuously generate a large amount of heat during operation. If the ventilation is not smooth, this heat cannot be dissipated in time, which will cause the temperature inside the distribution box to rise sharply. If it is in a high temperature environment for a long time, the performance of the electrical equipment will be greatly reduced and the service life will be significantly shortened. In more serious cases, it may cause electrical failures, which will pose a serious threat to the stable operation of the entire power system.

[0004] To achieve ventilation, some distribution boxes are equipped with vents, but these vents often lack effective filtering measures, and dust and debris in the air can easily enter and block the vents. Once the vents are blocked, the ventilation effect will deteriorate rapidly, further exacerbating the heat dissipation problem inside the distribution box. Moreover, blocked vents will also hinder air circulation inside the distribution box, causing moisture accumulation, which significantly increases the risk of electrical equipment being damaged by moisture.

[0005] Distribution boxes used in outdoor environments also face the serious problem of rainwater intrusion. Conventional vent designs are unable to effectively prevent rainwater from entering the distribution box. Once rainwater seeps in, it is very likely to cause electrical equipment to short-circuit and damage, posing a serious threat to the safe operation of the power system.

[0006] Furthermore, the filters or filtration devices in traditional distribution boxes are typically fixed and difficult to remove. When the filters become clogged with dust or other impurities, cleaning them is extremely difficult, often requiring specialized personnel with complex tools. This not only consumes significant time and labor, but also impacts the proper functioning of the distribution box. Furthermore, the removal and installation process can damage other components of the distribution box, further reducing its reliability and stability.

[0007] Therefore, we propose a distribution box with good ventilation effect. Utility Model Content

[0008] The purpose of the present utility model is to solve the shortcomings existing in the prior art. The poor ventilation of traditional distribution boxes causes heat to accumulate inside, affecting the performance and life of the equipment. The vents are easily blocked and lack effective filtration, which reduces the ventilation effect and easily causes moisture accumulation. When used outdoors, ordinary vents are difficult to prevent rainwater from intruding, causing equipment damage. In addition, traditional filters are difficult to disassemble, inconvenient to clean and costly.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A distribution box with good ventilation effect, comprising a frame assembly, wherein a back side ventilation structure is provided on the back side wall of the frame assembly;

[0011] Several support members are provided inside the frame assembly and near the bottom;

[0012] A filter assembly is provided below the support member, and a limit assembly is provided on the left side wall of the frame assembly;

[0013] As a preferred solution of the present invention, sliding grooves are provided on both side walls of the interior of the frame assembly near the bottom, and a bottom ventilation groove is provided at the bottom of the frame assembly.

[0014] As a preferred solution of the present invention, the back ventilation structure includes a back plate, a drainage groove is provided at the center of the back plate, a discharge outlet is provided at the bottom of the drainage groove, and several waterproof grooves are also provided through the back plate, several of the waterproof grooves are inclined, and a back filter is also provided inside the drainage groove.

[0015] As a preferred solution of the present invention, the filter assembly includes a bottom filter screen, a fixed block is provided on the left side wall of the bottom filter screen, the filter assembly is installed above the bottom air vent groove, and the fixed block is installed inside the sliding groove.

[0016] As a preferred solution of the present invention, the limiting assembly includes a component shell, a connecting rod is provided inside the component shell, a limiting block is fixedly connected to the right side wall of the connecting rod, a triangular block is fixedly connected to the right side wall of the limiting block, and the triangular block and the fixed block are used in combination.

[0017] As a preferred solution of the present invention, the limit assembly also includes a compression spring, which is sleeved on the connecting rod. A connecting column is also provided on the left side wall of the assembly housing. One end of the compression spring is fixedly connected to the limit block, and the other end is fixedly connected to the connecting column.

[0018] As a preferred solution of the present invention, a plug-in block is also provided on the left side wall of the connecting column, and a limiting plate is fixedly connected to the left side wall of the connecting rod. The connecting rod passes through the connecting column and the plug-in block, and the limiting plate and the connecting rod are integrated into one design.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In this utility model, the design of filter assembly and limit assembly is adopted to realize a filter assembly that can be quickly disassembled, which brings great convenience to the ventilation system of the distribution box. When the filter assembly is blocked by dust and other impurities, the user can easily remove the filter assembly for flushing without the need for complicated tools and professional techniques. This design not only ensures the cleanliness of the filter assembly and maintains good ventilation effect, but also greatly reduces maintenance costs and time. By regularly cleaning the filter, it can be ensured that the distribution box always maintains good air permeability, providing a strong guarantee for the stable operation of the internal electrical equipment.

[0021] At the same time, a back ventilation structure is set on the back side of the distribution box, and an inclined waterproof groove is set on the front and back sides of the drainage groove. The waterproof groove fully considers the dual needs of ventilation and waterproofing. The inclined waterproof groove can effectively guide the air flow and achieve good ventilation effect. At the same time, it can use the inclined angle to prevent rainwater from directly entering the distribution box. Even in severe weather conditions, it can ensure air circulation inside the distribution box, reduce the internal temperature, and improve the working efficiency and life of electrical equipment.

[0022] If some water accidentally seeps into the distribution box, there is no need to worry, because this situation is taken into consideration in the design. The seeped water will be guided to the drainage trough and finally discharged through the bottom drain. This design provides multiple waterproof protections for the distribution box. Even in the event of heavy rain or other unexpected situations, it can effectively prevent rainwater from damaging the internal electrical equipment. It greatly improves the reliability and safety of the distribution box in outdoor environments, and provides a solid foundation for the stable operation of the power system.

[0036] Example 1

[0037] like Figure 1-8 As shown, the utility model provides a technical solution: a distribution box with good ventilation effect, including a frame assembly 101, a back side ventilation structure 2 is provided on the back side wall of the frame assembly 101, and the back side ventilation structure 2 can be waterproof and dustproof on the basis of ventilation and is easy to disassemble;

[0038] Several support members 3 are provided inside the frame assembly 101 and near the bottom. The support members 3 are used to support the power distribution equipment.

[0039] A filter assembly 4 is provided below the support member 3, and a limit assembly 5 is provided on the left side wall of the frame assembly 101. The filter assembly 4 and the limit assembly 5 cooperate with each other to achieve ventilation at the bottom of the frame assembly 101 while having a good dust blocking effect, and the filter assembly 4 can be quickly disassembled and fixed.

[0040] The design of the filter component 4 and the limit component 5 realizes a quickly removable filter component 4, which brings great convenience to the ventilation system of the distribution box. When the filter component 4 is clogged with dust and other impurities, the user can easily remove the filter component 4 for flushing without the need for complicated tools and professional techniques. This design not only ensures the cleanliness of the filter component 4 and maintains good ventilation effects, but also greatly reduces maintenance costs and time. By regularly cleaning the filter, it can be ensured that the distribution box always maintains good air permeability, providing a strong guarantee for the stable operation of the internal electrical equipment.

[0041] At the same time, a back ventilation structure 2 is set on the back side of the distribution box, and an inclined waterproof groove 204 is set on the front and back sides of the drainage groove 202. The waterproof groove 204 fully considers the dual needs of ventilation and waterproofing. The inclined waterproof groove 204 can effectively guide the air flow to achieve good ventilation effect. At the same time, it can use the inclined angle to prevent rainwater from directly entering the distribution box. Even in severe weather conditions, it can ensure air circulation inside the distribution box, reduce the internal temperature, and improve the working efficiency and life of electrical equipment.

[0042] If some water accidentally seeps into the distribution box, there is no need to worry, because this situation is taken into consideration in the design. The seeped water is guided to the drainage trough 202 and finally discharged through the bottom drain port. This design provides multiple waterproof protections for the distribution box. Even in the event of heavy rain or other unexpected situations, it can effectively prevent rainwater from damaging the internal electrical equipment. It greatly improves the reliability and safety of the distribution box in outdoor environments and provides a solid foundation for the stable operation of the power system.

[0043] Example 2

[0044] like Figure 1-8 As shown, the present invention provides a technical solution: sliding grooves 102 are provided on both side walls of the interior of the frame assembly 101 and near the bottom, and a bottom ventilation groove 103 is provided at the bottom of the frame assembly 101.

[0045] The back ventilation structure 2 includes a back plate 201, a drainage groove 202 is opened at the center of the back plate 201, and an outlet 203 is opened at the bottom of the drainage groove 202. A plurality of waterproof grooves 204 are also opened through the back plate 201, and the plurality of waterproof grooves 204 are inclined. A back filter screen 205 is also provided inside the drainage groove 202, and the back filter screen 205 can be directly pulled out.

[0046] The filter assembly 4 includes a bottom filter screen 401 , a fixing block 402 is provided on the left side wall of the bottom filter screen 401 , the filter assembly 4 is installed above the bottom air-permeable groove 103 , and the fixing block 402 is installed inside the sliding groove 102 .

[0047] The limiting component 5 includes a component housing 501, and a connecting rod 502 is provided inside the component housing 501. A limiting block 503 is fixedly connected to the right side wall of the connecting rod 502, and a triangular block 504 is fixedly connected to the right side wall of the limiting block 503. The triangular block 504 and the fixed block 402 are used in conjunction with each other.

[0048] The limiting component 5 also includes a compression spring 505, which is sleeved on the connecting rod 502. A connecting column 506 is also provided on the left side wall of the component housing 501. One end of the compression spring 505 is fixedly connected to the limiting block 503, and the other end is fixedly connected to the connecting column 506.

[0049] A plug-in block 507 is also provided on the left side wall of the connecting column 506, and a limiting plate 508 is fixedly connected to the left side wall of the connecting rod 502. The connecting rod 502 passes through the connecting column 506 and the plug-in block 507, and the limiting plate 508 and the connecting rod 502 are integrated into one design.

[0050] The working process of the present invention: When using a distribution box with good ventilation effect, first, when ventilating the back side of the frame assembly 101, this solution sets a back ventilation structure 2, and opens a drainage groove 202 in the back plate 201, so that the drainage groove 202 has a certain drainage effect. Since the waterproof groove 204 of the back ventilation structure 2 is inclined, it is difficult for rainwater to enter the interior of the frame assembly 101. Even if some rainwater enters the back ventilation structure 2, it will be drained into the drainage groove 202, and finally discharged to the outside through the outlet 203 at the bottom of the drainage groove 202, thereby achieving a good waterproof effect. In addition, a back filter 205 is provided inside the drainage groove 202, so that when performing back ventilation, it also has a good dust-proof effect, and the back filter 205 can also be directly pulled out for replacement, which is very convenient.

[0051] Secondly, a filter component 4 is provided at the bottom of the frame assembly 101. The bottom filter 401 blocks dust when the frame assembly 101 performs bottom ventilation, and the filter component 4 can be quickly fixed and installed between the fixing block 402 and the limiting component 5. Since the filter component 4 is installed at the bottom, it is also installed differently from the back filter 205. Since the back filter 205 is installed vertically, it does not require special fixation, while the bottom filter 401 is installed horizontally. If it is not fixed, it will be offset under the action of external force.

[0052] The function of the limiting component 5 is to quickly fix and disassemble the filter component 4.

[0053] When in use, it is only necessary to push the filter assembly 4 in directly. During the pushing process, the fixing block 402 will be squeezed to the triangular block 504 end of the limiting assembly 5. Since the triangular block 504 is a slope, the triangular block 504 and the limiting block 503 will be displaced to the left through the connecting rod 502 under the action of force. During the displacement, the connecting rod 502 will store energy. When the fixing block 402 moves as a whole to the back side of the limiting block 503, the connecting rod 502 will bounce the limiting block 503 and the triangular block 504 back to their original position, thereby completing the fixation of the fixing block 402 and thus achieving the fixation of the filter assembly 4.

[0054] When the filter assembly 4 needs to be disassembled, it is only necessary to pull out the plug-in block 507, and the connecting rod 502 is limited by the limit plate 508 and the plug-in block 507, which will drive the connecting rod 502 to move to the left, causing the limit block 503 and the triangular block 504 to move to the left, and then the filter assembly 4 can be directly pulled out to complete the disassembly work.

[0055] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
