Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution cabinet using angle steel accessories. Background Art

[0002] A power distribution cabinet is a general term for a motor control center. It is a cabinet that integrates electrical components for power distribution. It is used in situations where the load is relatively dispersed and there are fewer circuits. It distributes the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. There are many types of power distribution cabinets. In order to ensure the strength of the cabinet, some of them use angle steel accessories as support. Angle steel accessories can increase the rigidity and stability of the distribution cabinet, so that the distribution cabinet can remain stable when subjected to greater mechanical stress and electrical loads. It is also convenient to connect with other distribution equipment and can adapt to different environments and conditions.

[0003] However, the distribution cabinet using angle steel accessories may have some disadvantages. Angle steel is a heavier material, and the distribution cabinet using angle steel accessories will also be relatively heavy. After being installed on the ground, after a period of time, especially after rainy days, the ground may become potholes due to gravity, causing the distribution box to tilt. After the distribution box tilts, the electrical devices installed inside are prone to malfunction, which may cause safety problems such as leakage and short circuit. In addition, angle steel is not a fireproof material. Once a fire occurs, the distribution cabinet may fuel the spread of the fire. For this reason, we have proposed a distribution cabinet using angle steel accessories. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 A power distribution cabinet using angle steel accessories includes a power distribution cabinet body 1, a cabinet door 2 is hinged on the front side of the power distribution cabinet body 1, a plurality of ventilation holes 3 are opened at the lower ends of both sides of the power distribution cabinet body 1, four supporting devices 4 are provided on both sides of the power distribution cabinet body 1 corresponding to the ventilation holes 3, a built-in base 6 is fixedly installed at the bottom of the inner cavity of the power distribution cabinet body 1, a cooling fan 7 is provided in the built-in base 6, a mounting frame 8 is fixedly installed on the upper surface of the built-in base 6, support plates 14 are fixedly connected to the upper ends of both sides of the inner wall of the power distribution cabinet body 1, and a fire extinguishing powder box 15 is inserted between the support plate 14 and the top inner wall of the power distribution cabinet body 1.

[0025] Furthermore, the inner cavity of the built-in base 6 is hollow and communicated with the ventilation hole 3 , and a heat dissipation fan 7 is fixedly plugged into the top of the built-in base 6 .

[0026] Furthermore, the supporting device 4 includes an L-shaped mounting plate 9, an extension plate 10, a threaded rod 11 and a supporting base plate 12. The lower end of the side of the distribution cabinet body 1 is fixedly connected to the L-shaped mounting plate 9, and two extension plates 10 are fixedly connected to the middle of the side of the L-shaped mounting plate 9 away from the distribution cabinet body 1. The two extension plates 10 are threadedly connected with threaded rods 11, and the lower end of the threaded rods 11 is fixedly connected to the supporting base plate 12.

[0027] Furthermore, a cross-shaped groove 13 is formed on the top of the threaded rod 11 , and the inner wall of the cross-shaped groove 13 is a rough structure.

[0028] Furthermore, 18 is fixedly connected to the middle of the bottom inner wall of the fire extinguishing powder box 15, and thin aluminum plates 17 are placed on 18 and at both ends of the bottom inner wall of the fire extinguishing powder box 15. A fastening bolt 16 is threadedly connected to the middle of the upper surface of 18, and the lower end of the fastening bolt 16 presses the thin aluminum plates 17 on both sides. The fire extinguishing powder box 15 is filled with fire extinguishing powder.

[0029] Working principle: After the device is installed, the overall levelness of the distribution cabinet can be adjusted by continuously adjusting the supporting device 4. Specifically, the lower end of the L-shaped mounting plate 9 has a certain height. When the four supporting devices 4 are installed at the bottom of the distribution cabinet, the overall height of the distribution cabinet can be increased. After the height is increased, it is not only convenient for wiring at the lower end, but also can prevent water accumulation and improve the utilization rate of the space; if the distribution cabinet is tilted, the cross-shaped groove 13 in the supporting device 4 at the other end of the tilted end is adjusted, and the cross-shaped groove 13 is rotated so that the cross-shaped groove 13 moves up and down in the extension plate 10, and the support bottom plate is adjusted by adjusting the height. 12 is positioned, and the height of this end is raised by supporting the ground with the support base 12, so as to ensure the horizontality of the distribution cabinet; the cooling fan 7 installed in the built-in base 6 can dissipate the heat inside the distribution cabinet when the equipment in the distribution cabinet is running, and the heat is dissipated to the external environment through the shutter 5; when a fire occurs inside the distribution cabinet, the temperature of the flame is generally above 600 degrees Celsius, and the thin aluminum plate 17 will begin to soften at about 300 degrees Celsius. When the thin aluminum plate 17 softens, the fire extinguishing powder in the fire extinguishing powder box 15 will press the thin aluminum plate 17 to the inside of the distribution cabinet due to gravity, which can hinder the spread of fire and reduce damage to internal equipment.
