Description

Technical Field

[0001] This utility model relates to the field of electrical equipment safety technology, specifically to an explosion-proof housing structure for a power distribution switch control device. Background Technology

[0002] In power systems, distribution switch control equipment plays a crucial role. However, in certain special environments, such as coal mines and chemical plants where flammable and explosive gases exist, if the distribution switch control equipment does not have explosion-proof functions, an internal fault that causes an electric arc or spark can easily lead to an explosion, seriously threatening the safety of personnel and the stable operation of equipment. Therefore, designing an explosion-proof housing structure for distribution switch control equipment is particularly important.

[0003] Referring to the explosion-proof enclosure of a power distribution switch control device (CN213753472U), the enclosure contains an explosion-proof mesh frame with perforations. Symmetrical fixing plates are fixedly connected to the sides of the mesh frame. The enclosure contains a mounting chamber with an elastic block fitted into its inner wall. A cover plate is fixedly connected to one surface of the elastic block, and an explosion-proof mesh plate is laminated inside the cover plate. Both the explosion-proof mesh plate and the explosion-proof mesh frame are made of aluminum alloy. An extension is provided on the side of the explosion-proof mesh plate, and a reinforcing plate is fixedly connected to one surface of the extension. The explosion-proof mesh frame and mesh plate of the explosion-proof enclosure for electrical switch control equipment not only improve the explosion-proof function of the enclosure, but also reduce the weight of the enclosure by using aluminum alloy material. Furthermore, the material of the box and cover is insulating engineering plastic, which can prevent leakage and improve the safety of the enclosure. As can be seen from the above, although this enclosure structure can be well applied and has explosion-proof performance, the heat dissipation performance of this enclosure structure is usually average, which makes the internal components of the enclosure prone to burn-out due to high temperature, which often troubles people. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof housing structure for power distribution switch control equipment, so as to solve the problem that although the housing structure mentioned in the background art can be well applied and has explosion-proof performance, the heat dissipation performance of the housing structure is usually average, which makes the internal components of the housing prone to burn-out due to high temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof housing structure for a power distribution switch control device, comprising an aluminum alloy housing, a first aluminum alloy frame at the edge of the surface of the aluminum alloy housing, an aluminum alloy cover on the side of the first aluminum alloy frame away from the aluminum alloy housing, a second aluminum alloy frame at the edge of the inner wall of the aluminum alloy cover, the inner wall of the second aluminum alloy frame contacting the surface of the first aluminum alloy frame, a reinforcing rib on the inner wall of the aluminum alloy housing, a temperature sensor installed on the inner wall of the aluminum alloy housing inside the reinforcing rib, a microcontroller installed on the inner wall of the aluminum alloy housing on the side of the temperature sensor, the input terminal of the microcontroller being electrically connected to the output terminal of the temperature sensor, heat dissipation vents on both sides of the bottom inner wall of the aluminum alloy housing, one end of the heat dissipation vent extending to the outside of the aluminum alloy housing, a fan installed inside the aluminum alloy housing on one side of the heat dissipation vent, the input terminal of the fan being electrically connected to the output terminal of the microcontroller, two positioning seats on both sides of the outer wall of the aluminum alloy housing, a semi-waist-shaped positioning hole on one side of the positioning seat.

[0006] Preferably, a plurality of locking nuts are provided on the outer wall of the first aluminum alloy frame away from the second aluminum alloy frame, and a plurality of locking bolts are installed at the edge of the surface of the second aluminum alloy frame. One end of the locking bolt passes through the second aluminum alloy frame and the first aluminum alloy frame in sequence and is threadedly connected to the locking nut. By having one end of the locking bolt pass through the second aluminum alloy frame and the first aluminum alloy frame in sequence and screwed into the locking nut, the second aluminum alloy frame is bolted and installed on the surface of the first aluminum alloy frame.

[0007] Preferably, an H-shaped mounting base is provided on the inner wall of the aluminum alloy shell above the heat dissipation mesh, and an aluminum alloy baffle is provided below the H-shaped mounting base. The outer wall of the aluminum alloy baffle contacts the inner wall of the aluminum alloy shell. The aluminum alloy baffle is provided to block and close the heat dissipation mesh.

[0008] Preferably, a lifting cylinder is installed at the center of the top of the H-shaped component holder. The input end of the lifting cylinder is electrically connected to the output end of the microcontroller. The bottom end of the lifting cylinder passes through the H-shaped component holder and is provided with a connecting block. The bottom end of the connecting block is fixedly connected to the top of the aluminum alloy stop. The lifting cylinder is used to drive the aluminum alloy stop to perform lifting and lowering operations.

[0009] Preferably, the H-shaped component holder has guide holes on both sides inside, and both ends of the guide holes extend to the outside of the H-shaped component holder. The guide holes are provided to allow the guide rod to be movably positioned.

[0010] Preferably, a guide rod is movably connected inside the guide hole, with both ends of the guide rod extending to the outside of the guide hole. The bottom end of the guide rod is connected to the top end of the aluminum alloy stop. The guide rod is provided to limit the movement range of the aluminum alloy stop in conjunction with the guide hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the explosion-proof housing structure of the power distribution switch control equipment not only reduces the phenomenon of burning of the inner components of the aluminum alloy housing due to high temperature, but also ensures the explosion-proof performance of the housing structure during use, and reduces the space occupied by the housing structure during use.

[0012] (1) The temperature inside the aluminum alloy housing is monitored by a temperature sensor. If the temperature inside the aluminum alloy housing is too high and exceeds the set value, the microcontroller will start the fan so that the outside air is introduced into the aluminum alloy housing through the heat dissipation mesh on the right side and the air inside the aluminum alloy housing is discharged to the outside environment through the heat dissipation mesh on the left side, so as to achieve the purpose of air cooling of the components inside the aluminum alloy housing, thereby reducing the phenomenon of burn-out of the components inside the aluminum alloy housing due to high temperature.

[0013] (2) By tightening the locking bolt, one end of the locking bolt passes through the second aluminum alloy frame and the first aluminum alloy frame and is screwed into the locking nut, so that the second aluminum alloy frame is bolted to the surface of the first aluminum alloy frame. The aluminum alloy shell cover can then block and close the opening area of ​​the aluminum alloy shell. Then, the aluminum alloy stop is driven to move downward by the lifting cylinder, so that the aluminum alloy stop moves the guide rod downward inside the guide hole, so that the aluminum alloy stop moves down to the heat dissipation mesh position to block and close it. In this way, the control equipment components can be sealed in the aluminum alloy shell, thereby ensuring the explosion-proof performance of the shell structure during use.

[0014] (3) By attaching the positioning seat to the wall, and then using bolts to pass through the semi-waist-shaped positioning hole and screw into the wall, the aluminum alloy shell can be wall-mounted on the wall, thereby reducing the space occupied by the shell structure during use.
