Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically to an auxiliary component for power distribution cabinets. Background Technology

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. They are used in situations where the load is relatively dispersed and there are few circuits. Motor control centers are used in situations where the load is concentrated and there are many circuits. They distribute the electrical energy from a circuit of the previous-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load, including primary distribution equipment, secondary distribution equipment, and final-level distribution equipment. Primary distribution equipment is collectively referred to as power distribution centers, which are centrally installed in the enterprise's substation, distributing electrical energy to different... The next level of power distribution equipment is located close to the step-down transformer, so it has higher requirements for electrical parameters and larger output circuit capacity. The second level of power distribution equipment is a general term for power distribution cabinets and motor control centers. Power distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the previous level of power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. The final level of power distribution equipment is collectively called lighting power distribution boxes. They are far away from the power supply center and are small-capacity distributed power distribution equipment.

[0003] For example, publication number CN214899456U discloses a power distribution cabinet, including a cabinet body and a locking block. The outer wall of the locking block has a sliding groove, and a spring is embedded inside the sliding groove. A protrusion is fixedly installed on one end of the cabinet door near the locking block, and a slider is fixedly installed on the outer wall of the protrusion. The slider is slidably connected inside the sliding groove, and its outer wall abuts against one end of the spring. In this utility model, when adjusting the interior of the power distribution cabinet, the door lock is opened, allowing the door to open. Then, the spring in the sliding groove compresses the slider, causing it to slide from the groove. The sliding groove drives the protrusion to rotate around a pivot, thus allowing the cabinet door to rotate along with the protrusion around the pivot, automatically opening the door. Furthermore, due to the spring's action, the cabinet door can always remain open, facilitating operation of the cabinet's interior and improving its usability.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Although this type of distribution cabinet allows the cabinet door to always be open, during use, the existing distribution cabinet body usually dissipates heat through ventilation holes. The ventilation holes are equipped with dust screens to block insects and other debris. However, the dust screens are usually fixed or embedded inside the ventilation holes, making disassembly and cleaning troublesome and the entire cleaning process inefficient. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary component for power distribution cabinets, which has the advantage of being easy to clean. This solves the problem that existing power distribution cabinets typically dissipate heat through ventilation openings, with dust filters installed inside the ventilation openings to block insects and other debris. However, these dust filters are usually fixedly installed or embedded inside the ventilation openings, making disassembly and cleaning cumbersome and resulting in low cleaning efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary component for a power distribution cabinet, comprising a power distribution cabinet body, a heat dissipation vent, and a dustproof mesh. The heat dissipation vent is located at the bottom rear side of the power distribution cabinet body, and the dustproof mesh is located at the bottom rear side of the power distribution cabinet body. A cleaning brush is movably connected to the top rear side of the dustproof mesh, and a mounting plate is fixedly connected to the rear side of the cleaning brush. A connecting mechanism is fixedly connected to the rear side of the power distribution cabinet body, and a linkage mechanism is provided on the front side of the mounting plate.

[0008] As a preferred embodiment of this utility model, the connecting mechanism includes a protective frame, the dustproof net is embedded inside the protective frame, a first square groove is provided on the rear side of the top of the protective frame, the inner wall of the first square groove is movably connected to the surface of the mounting plate, and a ventilation opening is provided on the rear side of the protective frame.

[0009] As a preferred embodiment of this utility model, the linkage mechanism includes a connecting plate, a baffle, and a second square groove. The second square groove is opened on the front side of the top of the protective frame. The inner wall of the second square groove is movably connected to the baffle. The rear side of the baffle is in contact with the front side of the dustproof net. The top of the baffle is fixedly connected to the connecting plate, and the bottom of the connecting plate is fixedly connected to the top of the mounting plate.

[0010] As a preferred embodiment of this utility model, a through groove is provided on the front side of the bottom of the inner wall of the protective frame, and a dust outlet is provided on the rear side of the bottom of the inner wall of the protective frame. The through groove is located at the bottom of the baffle, and the dust outlet is located at the bottom of the cleaning brush.

[0011] As a preferred embodiment of this utility model, a support frame is fixedly connected to the front side of the bottom of the protective frame, and a metal mesh is embedded in the inner wall of the ventilation opening.

[0012] As a preferred embodiment of this utility model, a fixing plate is fixedly connected to the top of the protective frame, and a rotating rod is provided on the rear side of the mounting plate. The end of the rotating rod near the main body of the distribution cabinet passes through the mounting plate, the fixing plate and the baffle in sequence and extends to the front side of the baffle. The rotating rod is threadedly connected to the mounting plate, the fixing plate and the baffle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting an installation plate and a cleaning brush, allows the installation plate to fix and limit the cleaning brush. Moving the installation plate downwards can drive the cleaning brush downwards to clean the back of the dustproof net. This solves the problem that existing power distribution cabinets usually dissipate heat through heat dissipation vents, and the dustproof nets inside the vents block insects and other debris. However, the dustproof nets are usually fixedly installed or embedded inside the vents, making disassembly and cleaning cumbersome and the entire cleaning process inefficient. This invention achieves the effect of easy cleaning.

[0015] 2. By setting a connecting mechanism, the protective frame can fix and limit the dustproof net, the first square groove can limit the mounting plate and cleaning brush in the front, back and left and right directions, thereby improving the stability of the cleaning brush moving up and down, and the ventilation port can keep the inside of the protective frame connected with the outside air.

[0016] 3. By setting a linkage mechanism, the second square groove can limit the movement of the baffle. By moving the connecting plate downward, the baffle can be moved downward to the rear side of the dustproof net, thereby preventing impurities from falling to the rear side of the dustproof net when the cleaning brush is cleaning it.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figures 1 to 4 As shown, the present invention provides an auxiliary component for a power distribution cabinet, including a power distribution cabinet body 1, a heat dissipation vent 2, and a dustproof net 3. The heat dissipation vent 2 is located at the bottom of the rear side of the power distribution cabinet body 1, the dustproof net 3 is located at the bottom of the rear side of the power distribution cabinet body 1, a cleaning brush 4 is movably connected to the top of the rear side of the dustproof net 3, a mounting plate 5 is fixedly connected to the rear side of the cleaning brush 4, a connecting mechanism 6 is fixedly connected to the rear side of the power distribution cabinet body 1, and a linkage mechanism 7 is provided on the front side of the mounting plate 5.

[0024] refer to Figure 4 The connecting mechanism 6 includes a protective frame 61, a dustproof net 3 is embedded inside the protective frame 61, a first square groove 62 is provided on the rear side of the top of the protective frame 61, the inner wall of the first square groove 62 is movably connected to the surface of the mounting plate 5, and a ventilation opening 63 is provided on the rear side of the protective frame 61.

[0025] As a technical optimization of this utility model, by setting the connecting mechanism 6, the protective frame 61 can fix and limit the dustproof net 3, the first square groove 62 can limit the mounting plate 5 and the cleaning brush 4 in the front, back and left and right directions, thereby improving the stability of the cleaning brush 4 moving up and down, and the ventilation port 63 can keep the interior of the protective frame 61 connected with the outside air.

[0026] refer to Figure 3 The linkage mechanism 7 includes a connecting plate 71, a baffle 72, and a second square groove 73. The second square groove 73 is opened on the front side of the top of the protective frame 61. The baffle 72 is movably connected to the inner wall of the second square groove 73. The rear side of the baffle 72 is attached to the front side of the dustproof net 3. The connecting plate 71 is fixedly connected to the top of the baffle 72. The bottom of the connecting plate 71 is fixedly connected to the top of the mounting plate 5.

[0027] As a technical optimization of this utility model, by setting the linkage mechanism 7, the second square groove 73 can limit the movement of the baffle 72. By moving the connecting plate 71 downward, the baffle 72 can be moved downward to the rear side of the dustproof net 3, thereby preventing impurities from falling to the rear side of the dustproof net 3 when the cleaning brush 4 cleans the dustproof net 3.

[0028] refer to Figure 4A through groove 8 is provided on the front side of the bottom of the inner wall of the protective frame 61, and a dust outlet 9 is provided on the rear side of the bottom of the inner wall of the protective frame 61. The through groove 8 is located at the bottom of the baffle 72, and the dust outlet 9 is located at the bottom of the cleaning brush 4.

[0029] As a technical optimization of this utility model, by setting a through groove 8 and a dust outlet 9, the impurities that are cleaned and dropped can fall to the outside of the protective frame 61 through the dust outlet 9. The through groove 8 facilitates the downward movement of the baffle 72. When the surface of the baffle 72 is in contact with the inner wall of the through groove 8, the baffle 72 can be stably positioned in front of the dustproof net 3.

[0030] refer to Figure 2 A support frame 10 is fixedly connected to the front side of the bottom of the protective frame 61, and a metal mesh 11 is embedded in the inner wall of the vent 63.

[0031] As a technical optimization of this utility model, by setting a support frame 10 and a metal mesh 11, the support frame 10 can support the descending baffle 72, and the metal mesh 11 can block rainwater, thereby preventing rainwater from directly adhering to the surface of the dustproof net 3 through the ventilation opening 63.

[0032] refer to Figure 2 and Figure 3 The top of the protective frame 61 is fixedly connected to a fixing plate 12. A rotating rod 13 is provided on the rear side of the mounting plate 5. The end of the rotating rod 13 near the main body 1 of the distribution cabinet passes through the mounting plate 5, the fixing plate 12 and the baffle 72 in sequence and extends to the front side of the baffle 72. The rotating rod 13 is threadedly connected to the mounting plate 5, the fixing plate 12 and the baffle 72.

[0033] As a technical optimization of this utility model, by setting a fixed plate 12 and a rotating rod 13, the fixed plate 12 enables the rotating rod 13 to position the baffle 72 and the mounting plate 5, thereby preventing the baffle 72 and the mounting plate 5 from falling when no one intervenes.

[0034] The working principle and usage process of this utility model are as follows: When cleaning the dustproof net 3, first, rotate the rotating rod 13 to disengage it sequentially from the baffle 72, the fixing plate 12, and the mounting plate 5. Then, by moving the connecting plate 71 up and down, the mounting plate 5 and the cleaning brush 4 can move up and down, thereby cleaning the dustproof net 3. At the same time, the downward movement of the connecting plate 71 can move the baffle 72 downward, thus preventing impurities from falling onto the back of the dustproof net 3 when the cleaning brush 4 is cleaning it. On the side, the debris that falls off can fall to the outside of the protective frame 61 through the dust outlet 9. After cleaning, the rotating rod 13 is screwed into the mounting plate 5, the fixing plate 12 and the baffle 72 in sequence to position the mounting plate 5 and the baffle 72. The metal mesh 11 can block rainwater, thereby preventing rainwater from directly adhering to the surface of the dustproof mesh 3 through the ventilation opening 63. Rainwater that enters the protective frame 61 can flow out through the dust outlet 9 and the through groove 8, thereby preventing rainwater from entering the interior of the main body of the distribution cabinet 1.

[0035] In summary, this auxiliary component for a power distribution cabinet, by setting up an mounting plate 5 and a cleaning brush 4, allows the mounting plate 5 to fix and limit the cleaning brush 4. Moving the mounting plate 5 downwards can drive the cleaning brush 4 downwards to clean the rear side of the dustproof net 3. This solves the problem that existing power distribution cabinets typically dissipate heat through ventilation openings, with dustproof nets inside the ventilation openings to block insects and other debris. However, the dustproof nets are usually fixedly installed or embedded inside the ventilation openings, making disassembly and cleaning cumbersome and the entire cleaning process inefficient.
