[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is suitable for occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy 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.

[0003] The power control equipment installed inside the distribution cabinet will generate heat during operation. If the heat is not evacuated in time, it will have an adverse effect on the power control equipment. Therefore, a heat dissipation device will be installed inside the distribution cabinet. However, there are many factors that affect the heat dissipation effect of the heat dissipation device. When the heat dissipation device fails, the power control equipment inside the distribution cabinet will heat up sharply. If this state is not discovered in time, it will affect the service life of the power control equipment in the distribution cabinet.

[0004] Therefore, in order to solve the above problems, a power distribution cabinet with temperature detection and alarm function is proposed. Utility Model Content

The four limiting protrusions all pass through the square frame, and the four limiting protrusions are respectively engaged with the clamping holes on the four right-angle support rods.

[0008] Preferably, both sides of the inner wall of the square frame are provided with sliding grooves, and both ends of the arc-shaped clamping plate are fixedly connected with clamping blocks, and the clamping blocks are slidably installed inside the sliding grooves.

The temperature sensor body 22 and the alarm body 3 are electrically connected. The electric control device and the detection component 2 are installed inside the cabinet 1 through the cooperation of the right-angle support rod 11 and the clamping hole 12 thereon. The square frame 21 and the right-angle support rod 11 are in contact and slided so that their relative positions can be adjusted accordingly with the installation of the electric control device. The temperature is monitored above the square frame 21 through the temperature sensor body 22, and the temperature sensor body 22 and the alarm body 3 are electrically connected. When the temperature sensed by the temperature sensor body 22 exceeds a certain value, the alarm body 3 sends out an alarm.

[0027] like Figure 2 and Figure 3 As shown, the square frame 21 is symmetrically installed with arc-shaped clamping plates 23 inside, and the side walls of the two arc-shaped clamping plates 23 are fixedly connected with limiting convex columns 231 near the edges of both ends, and the four limiting convex columns 231 all pass through the square frame 21. The four limiting convex columns 231 are respectively engaged with the clamping holes 12 on the four right-angle support rods 11. The square frame 21 fixes the detection component 2 to the right-angle support rod 11 through the mutual engagement between the limiting convex columns 231 on the arc-shaped clamping plates 23 and the clamping holes 12;

[0028] like Figure 3 and Figure 4 As shown, both sides of the inner wall of the square frame 21 are provided with slide grooves 211, and both ends of the arc-shaped clamping plate 23 are fixedly connected with clamping blocks 232, and the clamping blocks 232 are slidably installed inside the slide grooves 211. The arc-shaped clamping plate 23 increases the installation stability between the square frame 21 and the arc-shaped clamping plate 23 through the mutual sliding between the clamping blocks 232 and the slide grooves 211;

[0029] like Figure 3 and Figure 4As shown, a through circular hole 233 is provided at the center of the side wall of the two arc-shaped clamping plates 23, and a central guide rod 24 is slidably installed between the inner walls of the two through circular holes 233. The two ends of the central guide rod 24 are respectively fixed to the inner wall of the square frame 21. The square frame 21 is engaged with the through circular holes 233 on the arc-shaped clamping plates 23 through the central guide rod 24 to increase the installation stability of the arc-shaped clamping plates 23.

[0030] like Figure 3 and Figure 4 As shown, the outer wall sliding sleeve of the central guide rod 24 is provided with a spring 25, and the two ends of the spring 25 are respectively fixed to the adjacent side walls of the arc-shaped clamping plate 23, and the spring 25 provides an elastic force for the two arc-shaped clamping plates 23 to move away from each other. At this time, the limiting convex column 231 and the clamping hole 12 are mutually engaged. When the position of the detection component 2 needs to be adjusted, the arc-shaped clamping plates 23 are controlled to move closer to each other to overcome the elastic force of the spring 25. After the position adjustment of the detection component 2 is completed, the squeezing force on the arc-shaped clamping plates 23 is released, and the device is restored;

Rubber baffles 15 are installed on both sides of the side wall of the cover 13 near the discharge opening. The wires between the temperature sensor body 22 and the alarm body 3 are regulated by the cover 13 inside the cabinet 1. The rubber material of the rubber baffle 15 blocks the cable opening 14 while not preventing the wires from entering the cover 13 from the cable opening 14;

[0032] Working principle: The electric control device and the detection component 2 are installed inside the cabinet 1 through the cooperation of the right-angle support rod 11 and the clamping hole 12 thereon. The square frame 21 and the right-angle support rod 11 are in contact and slided so that their relative positions can be adjusted accordingly with the installation of the electric control device. The temperature is monitored by the temperature sensor body 22 above the square frame 21, and the temperature sensor body 22 and the alarm body 3 are electrically connected. When the temperature sensed by the temperature sensor body 22 exceeds a certain value, the alarm body 3 sounds an alarm. The wires between the temperature sensor body 22 and the alarm body 3 are regulated by the cover 13 inside the cabinet 1, and the rubber material of the rubber baffle 15 does not hinder the wires from entering from the wiring opening 14. The inside of the cover shell 13 blocks the cable opening 14 at the same time, and the arc-shaped clamping plate 23 increases the installation stability between the square frame 21 and the arc-shaped clamping plate 23 by sliding between the clamping block 232 and the slide groove 211. The square frame 21 increases the installation stability of the arc-shaped clamping plate 23 by engaging with the through circular hole 233 on the arc-shaped clamping plate 23 through the center guide rod 24. The spring 25 provides an elastic force for the two arc-shaped clamping plates 23 to move away from each other. At this time, the limiting boss 231 and the clamping hole 12 engage with each other. When the position of the detection component 2 needs to be adjusted, the arc-shaped clamping plates 23 are controlled to move closer to each other to overcome the elastic force of the spring 25. After the position adjustment of the detection component 2 is completed, the squeezing force on the arc-shaped clamping plate 23 is released and the device is restored.
