Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a moisture-proof and dust-proof outdoor power distribution cabinet. Background Technology

[0002] In modern power supply systems, outdoor distribution cabinets, as key equipment for power distribution and control, are widely distributed in various outdoor locations such as urban streets, industrial parks, and remote mountainous areas. They undertake the important task of converting high-voltage power into low-voltage power suitable for users, and distributing, controlling, and protecting the power. Due to the complex and variable outdoor environment, distribution cabinets face challenges from various harsh conditions such as high temperature, humidity, and dust. High temperatures can cause the temperature of electrical components inside the distribution cabinet to rise, accelerating component aging, reducing their service life, and even causing failures. Humid environments can easily cause electrical components to become damp and short-circuit, affecting the stability of power supply. Dust can penetrate into the distribution cabinet, cover the surface of components, hinder heat dissipation, and may cause problems such as poor contact. Therefore, developing an outdoor distribution cabinet with efficient heat dissipation and good dust and moisture protection performance is of vital importance for ensuring the safe and stable operation of the power system and improving power supply reliability.

[0003] Traditional outdoor power distribution cabinets typically rely on simple natural ventilation for heat dissipation, which involves opening vents in the cabinet and letting the natural convection of air carry away the heat. This method is effective when the ambient temperature is low and the ventilation is good. For moisture prevention, desiccants are usually placed inside the cabinet.

[0004] However, existing technologies have the problem of not being able to effectively dissipate heat while also preventing dust and moisture. During heat dissipation, since the cabinet is directly connected to the outside, a large amount of dust and moisture will enter the cabinet with the airflow. Dust accumulates on the surface of electrical components, which not only affects heat dissipation but also easily causes faults such as short circuits. Moisture will corrode the components and reduce their insulation performance. Therefore, a moisture-proof and dust-proof outdoor distribution cabinet is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a moisture-proof and dust-proof outdoor power distribution cabinet, which aims to improve the problem in the existing technology where the cabinet is directly connected to the outside, and a large amount of dust and moisture will enter the power distribution cabinet with the airflow, which not only affects heat dissipation, but also easily causes faults such as short circuits.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A moisture-proof and dust-proof outdoor power distribution cabinet includes a cabinet body, a dust cover fixedly connected to the top of the cabinet body, a heat dissipation frame fixedly connected to one side of the inside of the cabinet body, a heat dissipation vent opened inside the cabinet body, a heat dissipation fan installed inside the heat dissipation frame, a rotating component installed inside the heat dissipation frame, and a limit component installed inside the cabinet body.

[0008] The rotating assembly includes a support ring and a turntable. The outer wall of the support ring is fixedly connected to the inside of the heat dissipation vent. The turntable is rotatably connected to the inside of the support ring. A limit groove is formed inside the support ring. A limit post is fixedly connected to one side of the turntable. The limit post is slidably connected to the inside of the limit groove. A fixing ring is fixedly connected to the inside of the heat dissipation vent. The turntable is rotatably connected to the outer wall of the fixing ring. A blade is rotatably connected to one side of the fixing ring. A ventilation hole is formed inside the blade. A transmission rod is rotatably connected to one side of the turntable. One end of the transmission rod is rotatably connected to one side of the blade.

[0009] As a further description of the above technical solution:

[0010] A handle is fixedly connected to the outer wall of the turntable, and the handle is slidably connected inside the support ring.

[0011] As a further description of the above technical solution:

[0012] The limiting component includes a wire threading frame and a limiting frame. The wire threading frame is disposed inside the cabinet, and one side of the limiting frame is fixedly connected to the inside of the cabinet. The wire threading frame is slidably connected inside the limiting frame.

[0013] As a further description of the above technical solution:

[0014] The cabinet has a slot inside, and the cable tray has a sliding plate inside, which is slidably connected to the slot.

[0015] As a further description of the above technical solution:

[0016] A sliding column is fixedly connected to one side of the card plate, and the sliding column is slidably connected inside the wire threading frame.

[0017] As a further description of the above technical solution:

[0018] A spring is fitted on the outer wall of the sliding column, and the two ends of the spring are fixedly connected to the inside of the threading frame and the card plate, respectively.

[0019] As a further description of the above technical solution:

[0020] A hinge is fixedly connected to one side of the cabinet, and a cabinet door is fixedly connected to the other side of the hinge.

[0021] As a further description of the above technical solution:

[0022] One side of the cabinet door fits against one side of the cabinet body, and the cabinet door and the cabinet body are connected by the hinge.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the heat dissipation fan inside the heat dissipation vent is activated to absorb heat from inside the cabinet. The heat is discharged through the ventilation holes in the blades. Turning the handle drives the turntable to rotate inside the support ring. The turntable drives the transmission rod, which causes the blades to flip and open on one side of the fixed ring to adjust the opening degree of the air vent. This achieves effective heat dissipation and dust and moisture prevention. It solves the problem that the cabinet is directly connected to the outside, and a large amount of dust and moisture will enter the power distribution cabinet with the air flow, which not only affects heat dissipation but also easily causes short circuits and other faults. This improves the practicality of the power distribution cabinet.

[0025] 2. In this utility model, by inserting the cable guide frame between the limiting frames inside the cabinet, the internal locking plate of the cable guide frame slides into the cable guide frame under the pressure of the inner wall of the cabinet, compressing the spring. After the cable guide frame is fully slid in, the spring rebounds, causing the locking plate to lock into the slot inside the cabinet, thus achieving the effect of quick assembly and disassembly of the cable guide frame. This solves the problem of the complex fixing method of the cable guide frame in traditional distribution cabinets, making it difficult to disassemble and reinstall it without damaging the cabinet structure, resulting in difficulties in adjusting the internal layout of the distribution cabinet, thereby improving the flexibility of the distribution cabinet.

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 Figures 1-3 The present invention provides an embodiment of a moisture-proof and dust-proof outdoor power distribution cabinet, comprising a cabinet body 1, a dust cover 2 fixedly connected to the top of the cabinet body 1 to prevent external pollutants such as dust and rainwater from entering the cabinet body 1 and to ensure the safety of the internal electrical components, a heat dissipation frame 3 fixedly connected to one side inside the cabinet body 1, a heat dissipation vent 4 opened inside the cabinet body 1 to allow air circulation, thereby promoting temperature regulation inside the cabinet body 1, a heat dissipation fan is installed inside the heat dissipation frame 3, a rotating component is installed inside the heat dissipation frame 3, and a limit component is installed inside the cabinet body 1;

[0034] The rotating assembly includes a support ring 5 and a turntable 6. The outer wall of the support ring 5 is fixedly connected to the inside of the heat dissipation vent 4, and the turntable 6 is rotatably connected to the inside of the support ring 5. A limit groove 8 is formed inside the support ring 5, and a limit post 9 is fixedly connected to one side of the turntable 6. The limit post 9 is slidably connected inside the limit groove 8. The design of the limit groove 8 ensures that the turntable 6 can rotate within a set range, thereby controlling the opening and closing angle of the blades 12. A fixing ring 11 is fixedly connected inside the heat dissipation vent 4, and the turntable 6 is rotatably connected to the outer wall of the fixing ring 11. A blade 12 is rotatably connected to one side of the fixing ring 11. A ventilation hole 13 is formed inside the blade 12, which can effectively prevent external dust. While dust is being collected inside the cabinet 1, air circulation is also ensured. A drive rod 10 is rotatably connected to one side of the turntable 6, and one end of the drive rod 10 is rotatably connected to one side of the blade 12. A handle 7 is fixedly connected to the outer wall of the turntable 6, and the handle 7 is slidably connected inside the support ring 5. The user can manually adjust the position of the turntable 6 through the handle 7. A hinge 14 is fixedly connected to one side of the cabinet 1, and a cabinet door 15 is fixedly connected to one side of the hinge 14. One side of the cabinet door 15 fits against one side of the cabinet 1, and the cabinet door 15 and the cabinet 1 are connected by the hinge 14. The hinge 14 allows the cabinet door 15 to be opened and closed easily, protecting the electrical equipment inside the cabinet 1.

[0035] Reference Figure 1 , Figure 2 and Figure 4The limiting components include a cable guide 17 and a limiting frame 18. The cable guide 17 is installed inside the cabinet 1 and is used to support and organize the wires inside the cabinet 1 to ensure that the cables are not easily damaged by external physical forces inside the distribution cabinet. One side of the limiting frame 18 is fixedly connected to the inside of the cabinet 1, and the cable guide 17 is slidably connected to the inside of the limiting frame 18 to ensure that the position of the cable guide 17 can be flexibly adjusted to adapt to the wiring needs of different specifications of cables. A slot 16 is provided inside the cabinet 1, and a card plate 19 is slidably connected inside the cable guide 17. The card plate 19 is slidably connected inside the slot 16. A sliding column 20 is fixedly connected to one side of the card plate 19 and is slidably connected inside the cable guide 17. A spring 21 is sleeved on the outer wall of the sliding column 20. The two ends of the spring 21 are fixedly connected to the inside of the cable guide 17 and the card plate 19, respectively. The spring 21 enables the card plate 19 to achieve automatic rebound and provides the necessary release force during disassembly, ensuring a smooth disassembly and assembly process.

[0036] Working Principle: When heat dissipation is needed inside cabinet 1 during the use of this distribution cabinet, the heat is absorbed by the cooling fan inside the heat dissipation vent 4 and discharged through the ventilation holes 13 inside the blades 12, effectively preventing external dust from entering the cabinet 1. Furthermore, by turning the handle 7, the turntable 6 rotates inside the support ring 5. The turntable 6, under force, moves the transmission rod 10 on one side, causing the transmission rod 10 to rotate and open / close the blades 12 on one side of the fixed ring 11, thereby adjusting the opening and closing degree of the air vents and accelerating air circulation inside cabinet 1. This effectively dissipates heat and prevents dust and moisture from entering the cabinet 1. When assembling or disassembling the internal cable guide 17, first insert the cable guide 17 between the limiting frames 18 inside the cabinet 1. During this process, the retaining plate 19 inside the cable guide 17 will be squeezed by the inner wall of the cabinet 1, causing the retaining plate 19 to slide into the inside of the cable guide 17. At the same time, the retaining plate 19 compresses the spring 21 on one side. When the cable guide 17 is completely slid into the inside of the cabinet 1, the spring 21 releases the force and rebounds, thereby driving the retaining plate 19 to reset and lock it in the retaining groove 16 inside the cabinet 1 for fixation. When disassembling, simply pull the cable guide 17 outward so that the retaining plate 19 slides out of the retaining groove 16. This achieves the effect of quick assembly and disassembly of the cable guide 17, which facilitates the adjustment of the layout inside the cabinet 1.
