Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a waterproof and dustproof power distribution cabinet. Background Technology

[0002] A distribution cabinet is an electrical device used for centralized distribution and control of electrical energy. It is widely used in power systems in various fields such as industry, commerce, and residence. It can provide reliable protection for the electrical equipment inside the cabinet, and its core function is to ensure the safe and stable operation of the power system.

[0003] Distribution cabinets house numerous electrical components, facilitating centralized management and operation of the power system. Staff can monitor, maintain, and repair various circuits from a relatively centralized location. Distribution cabinets have a wide range of applications, but outdoor distribution cabinets need to cope with extreme weather. Ordinary cabinets lack sufficient sealing, which can easily lead to rainwater infiltration, causing short circuits or fires. In such cases, waterproof and dustproof distribution cabinets are needed to reduce external interference, extend equipment life, and reduce operation and maintenance costs.

[0004] Currently, waterproof and dustproof distribution cabinets on the market mainly consist of a cabinet body, seals, and internal electrical components. The electrical components operate inside the cabinet, which isolates them from external interference. The seals are used to fill gaps and ensure the waterproof and dustproof performance of the distribution cabinet. However, because the distribution cabinet adopts a sealed design to achieve good waterproof and dustproof performance, it is difficult for internal heat to dissipate, causing the electrical components to operate in a high-temperature environment, reducing their performance and lifespan. To solve the above problems, heat dissipation channels are usually opened on the outer shell of the distribution cabinet. However, the ventilation structure set up for heat dissipation is not easy to clean. After long-term use, dust accumulation will affect the dustproof effect and ventilation and heat dissipation performance, failing to meet the needs of users. Utility Model Content

[0032] 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.

[0033] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of a waterproof and dustproof power distribution cabinet, comprising a cabinet body 1. Ventilation covers 3 are fixedly connected to both the left and right sides of the inner wall of the cabinet body 1 for waterproofing and dustproofing. An intake fan 4 is fixedly connected to the lower middle part of the left side of the inner wall of the cabinet body 1, and an exhaust fan 5 is fixedly connected to the upper middle part of the right side of the inner wall of the cabinet body 1, enabling air circulation within the cabinet body 1. A filter screen 6 is fixedly connected to the bottom of the inner wall of the cabinet body 1 for filtering dust. A ventilation duct 7 is provided at the bottom of the cabinet body 1, and drain ports 8 are provided on the left and right sides of the bottom of the cabinet body 1 to remove dust from the cabinet body 1. A housing 9 is fixedly connected to the top left side of the ventilation duct 7, and a motor 10 is fixedly connected to the front side of the housing 9. The output end of the motor 10 passes through the housing 9 and is fixedly connected to a drive bevel gear 1. 1. The rotation of motor 10 can drive the rotation of active bevel gear 11. A fixed block 14 is fixedly connected to the top right side of ventilation duct 7. A threaded rod 13 is rotatably connected to the middle of the right end of the inner side of housing 9. A driven bevel gear 12 is fixedly connected to the left end of threaded rod 13. The driven bevel gear 12 meshes with the active bevel gear 11. The active bevel gear 11 drives the driven bevel gear 12 to rotate. The right end of threaded rod 13 passes through housing 9 and is rotatably connected to fixed block 14. A double-headed brush 15 is threadedly connected to the outside of threaded rod 13. The double-headed brush 15 moves along threaded rod 13. Grilles 17 are opened on both the left and right sides of cabinet 1 for ventilation. A rubber pad 18 is fixedly connected to the front side of the inner wall of cabinet 1 to prevent dust from entering cabinet 1 through door gaps.

[0034] Specifically, when the device needs ventilation and heat dissipation, the intake fan 4 is activated to introduce air into the ventilation hood 3 through the grille 17, and then into the ventilation duct 7 that communicates with the inside of the ventilation hood 3. Subsequently, the air flows through the filter screen 6 into the cabinet 1 to dissipate heat from the electrical components, and is discharged from the cabinet 1 through the exhaust fan 5 to complete the air circulation inside the cabinet 1 and achieve the purpose of heat dissipation. When the dust carried in the air is blocked by the filter screen 6 and accumulates on the filter screen 6 and in the ventilation duct 7, the motor 10 is activated to rotate in both forward and reverse directions, driving the active bevel gear 11 to rotate. The active bevel gear 11 drives the driven bevel gear 12 to rotate, and the driven bevel gear 12 drives the threaded rod 13 to rotate. The double-headed brush 15 can then move back and forth along the threaded rod 13 to clean the dust and sweep the dust out of the cabinet 1 through the drain port 8. At the same time, the rubber pad 18 can also prevent dust from entering the cabinet 1 through the door gap.

[0035] Reference Figure 2 , Figure 5 and Figure 6The wiring mechanism 2 includes mounting rails 201, both of which are fixedly connected to the rear side of the cabinet 1. Different electrical components can be mounted on the mounting rails 201. Multiple fixing plates 202 are fixedly connected at equal intervals to the bottom of each of the two mounting rails 201. Coil plates 203 are fixedly connected to the bottom front side of each of the multiple fixing plates 202 for orderly arrangement of the wiring. Slots 204 are provided on the left and right sides of the interior of each of the multiple coil plates 203. A movable plate 205 is provided inside the coil plate 203. Multiple wire grooves 206 are provided at equal intervals inside the coil plate 203 and outside the movable plate 205, allowing wiring to be categorized and placed into the wire grooves 206. An inner cavity 207 is provided inside the movable plate 205. A knob 208 is rotatably connected to the part. The top of the knob 208 passes through the inner cavity 207 and is fixedly connected to a disc 209. Rotating the knob 208 can drive the disc 209 to rotate. The top left and right sides of the disc 209 are provided with sliding grooves 210. The inside of the two sliding grooves 210 is slidably connected to a slider 211. The bottom of the two sliders 211 is fixedly connected to a locking block 212. When the slider 211 slides along the sliding groove 210, it can drive the locking block 212 to move linearly. The two locking blocks 212 are respectively engaged with the corresponding locking grooves 204. The front and rear sides of the two ventilation hoods 3 are fixedly connected to a pad 19. One side of the multiple pads 19 is threaded with a screw 20. One end of the screw 20 passes through the pad 19 and is threadedly connected to the cabinet 1.

[0036] Specifically, after the electrical components are installed on the mounting rail 201, the connected wires can be arranged in an orderly manner through the wire groove 206 between the coil plate 203 and the moving plate 205, making the wires clear at a glance. When a fault occurs in a certain wire, it can be quickly troubleshooted. Then, by rotating the knob 208, the disc 209 can be rotated, and the slider 211 will slide in the groove 210. At the same time, due to the action of the groove 210 and the inner cavity 207, the slider 211 drives the locking block 212 to move linearly, so that the locking block 212 disengages from the slot 204 opened in the coil plate 203. The moving plate 205 can then be removed from the coil plate 203, making it easier to repair the faulty wire. At the same time, the pads 19 and screws 20 on both sides of the ventilation cover 3 facilitate the disassembly and cleaning of the ventilation cover 3, avoiding dust accumulation that affects heat dissipation.

[0037] Reference Figure 1 , Figure 2 and Figure 4 Support legs 21 are fixedly connected to the four corners of the bottom of the cabinet 1 to support the cabinet 1 and prevent it from being flooded. A rainproof canopy 23 is fixedly connected to the top of the cabinet 1. Guide rails 16 are fixedly connected to the front and rear ends of the right side of the shell 9. The right ends of the two guide rails 16 pass through the double-headed brush 15 and are fixedly connected to the fixing block 14, which can guide and stabilize the double-headed brush 15.

[0038] Specifically, the support leg 21 can raise the cabinet 1 to prevent water from soaking the cabinet 1, the rainproof canopy 23 allows rainwater to slide off quickly and prevents rainwater from accumulating on the top of the cabinet, and the guide rail 16 can position and fix the double-headed brush 15.

[0039] Reference Figure 1 The cabinet body 1 is provided with a cabinet door 25. The upper and lower sides of the right side of the front wall of the cabinet door 25 are fixedly connected with hinges 26. The cabinet door 25 is rotatably connected to the cabinet body 1 through the hinges 26. An observation window 24 is opened in the middle of the front side of the cabinet door 25. A door lock 22 is fixedly connected to the left side of the front side of the cabinet door 25.

[0040] Specifically, pulling the door lock 22 causes the cabinet door 25 to rotate through the hinge 26 and the cabinet body 1, thereby opening the cabinet door 25. The cabinet door 25 has an observation window 24, which allows for easy observation of the operation of the electrical components inside the cabinet body 1.

[0041] Working principle: When ventilation is required, the device activates the intake fan 4 and the exhaust fan 5. The intake fan 4 draws outside airflow into the corresponding ventilation hood 3 behind the grille 17. The airflow then enters the ventilation duct 7, which is connected to the ventilation hood 3. The airflow then passes through the filter screen 6, where dust and impurities are trapped within the ventilation duct 7. The airflow then enters the cabinet 1 to dissipate heat from the electrical components. The exhaust fan 5 then expels the hot air from the cabinet 1 through the grille 17, forming a dustproof and waterproof ventilation and heat dissipation cycle. Dust accumulation in the filter screen 6 and ventilation duct 7 can impair heat dissipation. When the motor 10 is started, the active bevel gear 11 is driven to rotate. The active bevel gear 11 drives the meshing driven bevel gear 12 to rotate. The driven bevel gear 12 then drives the threaded rod 13 to rotate. When the threaded rod 13 rotates, the double-headed brush 15 can move. The reciprocating motion of the double-headed brush 15 is completed by the forward and reverse rotation of the motor 10 to clean the dust of the filter screen 6 and ventilation duct 7. The dust can be discharged through the drain port 8 at the bottom of the cabinet 1. After long-term use, dust will not accumulate and affect the dustproof effect and ventilation and heat dissipation performance.

[0042] Furthermore, when it is necessary to organize and troubleshoot the wiring of the electrical components inside the device, the electrical components can be placed on the mounting rail 201, and the connected wires pass through the wire groove 206 between the coil plate 203 and the movable plate 205 connected to the fixed plate 202, which can achieve reasonable, clear and orderly classification of the wiring. When a fault occurs in a certain wiring, the disc 209 in the inner cavity 207 of the movable plate 205 is rotated by rotating the knob 208. When the disc 209 rotates, it drives the sliders 211 on the left and right sides to move along the corresponding grooves 210. At the same time, the sliders 211 drive the locking block 212 to move and retract into the inner cavity 207 and disengage from the locking groove 204 of the coil plate 203, so that the movable plate 205 can be disengaged from the coil plate 203, making it easier for the staff to troubleshoot and repair the faulty wiring.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
