Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a distribution box with protective functions. Background Technology

[0002] Industrial distribution boxes are devices specifically designed to provide power distribution and control for industrial production lines. They distribute electrical energy from upstream power sources (such as substations or distribution rooms) to specific electrical equipment (such as motors, frequency converters, heaters, etc.) according to the power needs of each piece of equipment on the production line. Simultaneously, they control and protect the power supply to these devices, ensuring the continuous and stable operation of the production line. However, existing distribution boxes have some shortcomings, such as:

[0003] The distribution box installation structure and distribution box described in application number CN202420138419.2 lack active heat dissipation or protective structures, relying solely on natural heat dissipation. In high-temperature environments, electrical components are prone to accelerated aging due to heat accumulation, and may even cause short circuits and other malfunctions. Furthermore, the heat dissipation holes lack dustproof and waterproof designs, allowing particles from dusty areas or moisture from humid environments to easily penetrate the box, leading to potential hazards such as wiring corrosion and poor contact. This problem is particularly pronounced in industrial dust workshops or rainy areas, where wiring is mixed with electrical components, necessitating a complete power outage of the distribution box during maintenance. This not only reduces maintenance efficiency but may also disrupt the operation of surrounding equipment due to unnecessary power outages. Additionally, the risk of live operation is high, and the lack of an independent isolation structure increases the risk of electric shock or accidental contact, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a distribution box with protective functions to solve the problem mentioned in the background art that existing equipment on the market is not equipped with active heat dissipation or protective structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a distribution box with protective function, including a box body, a hanging buckle, a flow guide, a fixing rail, bolt holes, a support frame, and a conduit;

[0006] The side of the enclosure is equipped with a heat dissipation mechanism, which includes a shroud, heat dissipation fins, a motor, and fan blades. The motor drives the fan blades to rotate, drawing airflow from the shroud and blowing it onto the heat dissipation fins, directly providing heat dissipation for the enclosure.

[0007] As a preferred technical solution of this utility model, the side of the box is fixedly connected to a fixed rail, there are two parallel fixed rails, a second cover plate is slidably connected inside the fixed rail, the second cover plate is slidably connected to the box, the top of the fixed rail is a circular structure and the side is a straight track, the side of the second cover plate is fixed with a button and a pair of handles in parallel, and the whole box is made of stainless steel.

[0008] Using the above technical solution, the device can rotate after the second cover plate is pulled out through the fixed rail structure. The silicone sealing ring at the joint can ensure the sealing of the second cover plate. The second cover plate slides to close through the fixed rail, and the circular structure at the top of the rail can guide rainwater to drip along the edge to avoid seepage.

[0009] As a preferred technical solution of this utility model, the box body is divided into two parts: the upper part of the box body is the electrical part, the lower part of the box body is the wiring part, the first cover plate is fixedly threaded at the bottom of the box body, and the connecting part of the upper and lower parts of the first cover plate is fixedly connected to the conduit. There are six conduits in total, arranged in a straight line. A pair of handles are fixed parallel to the side of the first cover plate.

[0010] Using the above technical solution, the conduit is made of flame-retardant rubber to prevent cable wear and insect intrusion. The upper part of the enclosure contains electrical components such as circuit breakers and contactors, which are independently sealed by the second cover plate. The live parts are isolated from the wiring parts for maintenance, which greatly improves safety.

[0011] As a preferred technical solution of this utility model, the bottom of the box has an inlet port, and a support frame is fixedly connected to the bottom of the box, with bolt holes provided below the support frame;

[0012] The above technical solution, with its support frame and anchor bolts designed to enhance impact resistance, and its lifting buckles for easy hoisting and transportation, is suitable for complex outdoor installation environments.

[0013] As a preferred technical solution of this utility model, a flow guide is fixedly connected to the side of the housing, a motor is fixedly connected to the inside of the flow guide, and heat dissipation fins are embedded and fixed on the side of the flow guide. Both the upper and lower ends of the flow guide are air outlets.

[0014] By adopting the above technical solution, the combination of forced convection and heat dissipation fins significantly improves heat dissipation efficiency compared to traditional natural heat dissipation, ensuring that the operating temperature of electrical components is below the safe threshold.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0028] Please see Figures 1-6 The present invention provides a protective distribution box, comprising a box body 1, a hanging buckle 2, a flow guide 3, a fixed rail 4, bolt holes 5, a support frame 6, a handle 7, a first cover plate 8, a button 9, a second cover plate 10, a cable inlet 11, heat dissipation fins 12, a motor 13, a fan blade 14, a terminal block 15, and a conduit 16.

[0029] The heat dissipation mechanism includes a shroud 3, heat dissipation fins 12, a motor 13, and fan blades 14. The motor 13 drives the fan blades 14 to rotate, drawing airflow from the shroud 3 and blowing it onto the heat dissipation fins 12 to achieve forced convection heat dissipation. Two parallel fixed rails 4 are fixedly connected to the side of the housing 1. The second cover plate 10 is slidably connected inside the fixed rails 4. The second cover plate 10 has a button 9 and a pair of handles 7 fixedly fixed on its side. The circular structure at the top of the fixed rails 4 and the straight track design on the side, together with the silicone sealing ring at the joint, not only ensure the sealing of the second cover plate 10 but also guide rainwater to drip along the edge to avoid seepage.

[0030] The enclosure 1 is divided into upper and lower parts. The upper part is the electrical part, and the lower part is the wiring part. The first cover plate 8 is fixed at the bottom with threads. Six flame-retardant rubber conduits 16 arranged in a straight line are fixedly connected to the first cover plate 8 and the connection between the upper and lower parts. A pair of handles 7 are fixed parallel to the side of the first cover plate 8 to isolate the live parts from the wiring parts for maintenance. The bottom of the enclosure 1 has a cable inlet 11, and a support frame 6 is fixedly connected below it. Bolt holes 5 are opened below the support frame 6 to enhance impact resistance. The side of the enclosure 1 is fixedly connected to the air guide 3. The motor 13 is fixedly connected inside the air guide 3. The side is embedded with heat dissipation fins 12. Both the upper and lower ends are air outlets. The combination of forced convection and heat dissipation fins 12 greatly improves heat dissipation efficiency. The entire enclosure 1 is made of stainless steel, which has good corrosion resistance and strength. The lifting buckle 2 facilitates hoisting and transportation and is suitable for complex outdoor installation environments.

[0031] Working principle: When using a distribution box with protective function, when the temperature inside the box 1 rises, the temperature sensor triggers the built-in intelligent temperature control module, the motor 13 drives the fan blade 14 to rotate, and air is drawn in from the air inlet of the guide shroud 3, cooled by the heat dissipation fins 12 and discharged from the upper and lower air outlets, forming a hot and cold air circulation.

[0032] When working outdoors, the arc-shaped deflector 3 guides rainwater to drip off along the edge, and the silicone sealing ring prevents moisture from seeping in.

[0033] When inspecting electrical components, remove the bolts to unlock the second cover plate 10, and open the cover plate directly using the handle 7. When inspecting circuits, remove the first cover plate 8 to access the terminal block 15 without touching live components.

[0034] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
