Technical Field

[0001] This application relates to the field of switch cabinets, and particularly to a dust-proof high and low voltage switch cabinet. Background Art

[0002] A switch cabinet is an electrical device. The main function of the switch cabinet is to switch on and off, control, and protect electrical equipment during the processes of power generation, power transmission, power distribution, and power conversion in the power system.

[0003] Referring to the Chinese utility model patent with the patent number CN216598617U, a switch cabinet is disclosed, which includes a cabinet body, a base, a support plate, and a mounting seat. A cross bar is fixedly installed on the inner bottom wall of the base. Both ends of the cross bar are sleeved with sliding sleeves. Springs are sleeved on the surface of the cross bar on the sides where the two sliding sleeves are away from each other. The top of the sliding sleeve is rotatably connected to a support rod, and the end of the support rod away from the sliding sleeve is rotatably connected to the lower surface of the support plate.

[0004] In actual use, when the electrical equipment in the switch cabinet operates, heat will be generated. If the heat cannot be dissipated in time, it will affect the operation and lifespan of the equipment, which needs to be improved. Summary of the Invention

[0005] In order to facilitate the heat dissipation of the switch cabinet, this application provides a dust-proof high and low voltage switch cabinet.

[0006] A dust-proof high and low voltage switch cabinet provided by this application adopts the following technical solutions:

[0007] A dust-proof high and low voltage switch cabinet includes a cabinet body. The cabinet body is provided with an installation cavity. A heat dissipation seat is arranged at the top of the cabinet body. The heat dissipation seat is provided with a heat dissipation cavity. The heat dissipation cavity communicates with the installation cavity. A partition board is arranged on the cavity wall of the heat dissipation cavity. A heat dissipation fan is arranged at one end of the partition board close to the installation cavity. The partition board is provided with a first heat dissipation hole. The first heat dissipation hole penetrates through the partition board. The penetration direction of the first heat dissipation hole is the vertical direction. A sliding groove is further arranged on the cavity wall of the heat dissipation cavity. The extending direction of the sliding groove is the horizontal direction. A heat expansion block is arranged at the bottom of the sliding groove. The heat expansion block is provided with a sliding plate. The sliding plate slides on the groove wall of the sliding groove. The sliding plate is provided with a second heat dissipation hole. The second heat dissipation hole penetrates through the sliding plate. The second heat dissipation hole is used to communicate with the first heat dissipation hole. When the temperature in the heat dissipation cavity rises, the heat expansion block expands due to heat, causing the sliding plate to move, and the first heat dissipation hole communicates with the second heat dissipation hole. When the temperature in the heat dissipation cavity drops, the heat expansion block contracts, causing the sliding plate to move towards the direction close to the bottom of the sliding groove, and the first heat dissipation hole is misaligned with the second heat dissipation hole.

[0008] By adopting the above technical solution, a cooling fan is provided to make the air in the cooling cavity flow, facilitating overall temperature reduction. At this time, the first heat dissipation hole and the second heat dissipation hole are misaligned, reducing the entry of dust. As the temperature continues to rise, the heat expansion block expands, causing the first heat dissipation hole and the second heat dissipation hole to communicate. At this time, with the rotation of the cooling fan, gas exchange between the inside and outside of the cooling cavity is carried out, facilitating overall heat dissipation.

[0009] Optionally, the heat expansion block is provided with a connecting spring, the connecting spring connects the heat expansion block and the sliding plate, and the elastic force of the connecting spring restricts the sliding plate from moving away from the heat expansion block; one end of the sliding plate away from the connecting spring is provided with a delay member, and the delay member is used to restrict the sliding plate from moving towards the bottom of the sliding groove; when the heat expansion block expands and pushes the sliding plate to move, the first heat dissipation hole and the second heat dissipation hole communicate. When the temperature of the cooling cavity drops, the heat expansion block contracts, causing the sliding plate to tend to move towards the bottom of the sliding groove, and the delay member restricts the sliding plate from moving towards the bottom of the sliding groove.

[0010] By adopting the above technical solution, a delay member is provided. By restricting the sliding of the sliding plate with the delay member, the situation of the first heat dissipation hole and the second heat dissipation hole switching back and forth between the communicating and misaligned states is reduced, making the overall heat dissipation more stable.

[0011] Optionally, the delay member includes a delay spring, a first delay magnet, and a second delay magnet. The delay spring is located at one end of the sliding plate away from the connecting spring. The delay spring connects the first delay magnet. A relief groove is provided on the wall of the cooling cavity, and the second delay magnet is located at the bottom of the relief groove. The magnetic forces of the first delay magnet and the second delay magnet attract each other; when the heat expansion block expands, the sliding plate moves, causing the first delay magnet to move towards the second delay magnet. The magnetic forces of the first delay magnet and the second delay magnet cause the first delay magnet to move towards the second delay magnet, and the delay spring pulls the sliding plate towards the second delay magnet.

[0012] By adopting the above technical solution, the first delay magnet and the second delay magnet are provided. When the sliding plate moves and causes the first delay magnet to move towards the second delay magnet, the magnetic forces of the first delay magnet and the second delay magnet facilitate the movement of the sliding plate. When the sliding plate moves towards the bottom of the sliding groove, the magnetic forces of the first delay magnet and the second delay magnet restrict the movement of the sliding plate. Through such a setting, the frequency of the first heat dissipation hole and the second heat dissipation hole communicating and misaligning is reduced, making the overall heat dissipation more stable.

[0013] Optionally, the partition plate is provided with heat dissipation ridges. There are multiple heat dissipation ridges, and the heat dissipation ridges are evenly spaced. A heat dissipation groove is left between adjacent heat dissipation ridges, and the first heat dissipation hole is located at the bottom of the heat dissipation groove.

[0014] By adopting the above technical solution, the contact area between the partition plate and the air is increased by providing the heat dissipation ribs, which facilitates the overall heat dissipation, thereby improving the overall heat dissipation effect.

[0015] Optionally, the heat dissipation cavity is provided with a control groove, the control groove is provided with a sliding rod, the sliding rod slides in the control groove, the sliding direction of the sliding rod is the extension direction of the heat dissipation ridge, the sliding rod is provided with an exhaust piece, and the exhaust piece is used to absorb dust between adjacent heat dissipation ridges.

[0016] By adopting the above technical solution, a sliding rod and a vacuum piece are set. In actual use, there is dust deposition in the heat dissipation cavity. The vacuum piece is used to absorb the dust between adjacent heat dissipation ribs. Secondly, the vacuum piece plays a role in gas exchange by exhausting the gas, which facilitates the overall heat dissipation operation.

[0017] Optionally, the partition plate is provided with a linkage groove, the linkage groove is provided at a side of the partition plate close to the sliding plate, the sliding plate is provided with a strip hole, the strip hole is connected to the linkage groove, the bottom of the linkage groove is provided with a linkage spring, the linkage spring is provided with a linkage block at one end away from the bottom of the linkage groove, the linkage block is embedded in the strip hole, and the linkage block is provided with an inclined surface, and the inclined surface is used to abut against the hole wall of the strip hole; when the sliding plate moves in a direction away from the bottom of the sliding groove, the inclined surface of the linkage block abuts against the hole wall of the strip hole, and the movement of the sliding plate causes the linkage block to move in a direction close to the bottom of the linkage groove; the partition plate is provided with a linkage hole, the linkage hole is located at one end of the partition plate away from the linkage groove, the linkage hole passes through the partition plate to the linkage groove, the linkage block is connected with a control rod, and the control rod passes through the linkage hole, the heat dissipation cavity is provided with a contact sensor, the contact sensor is electrically connected to a driving member, and the driving member is used to drive the sliding rod to move, and when the control rod moves and abuts against the contact sensor, the contact sensor sends a signal and causes the driving member to drive the sliding rod to move.

[0018] By adopting the above technical solution, in actual use, there is dust between the heat dissipation ridges. Before the heat dissipation hole 1 is connected with the heat dissipation hole, the movement of the sliding plate causes the linkage to move quickly and contact the contact sensor. The contact sensor causes the driving part to drive the sliding rod to move and perform an overall dust adsorption operation, thereby reducing the chance of dust falling and improving the overall dust removal effect.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. A heat dissipation fan is provided to make the air flow in the heat dissipation cavity, facilitating overall cooling. At this time, the first heat dissipation hole and the second heat dissipation hole are misaligned, reducing the entry of dust. As the temperature continues to rise, the heat-expandable block expands, causing the first heat dissipation hole and the second heat dissipation hole to communicate. At this time, with the rotation of the heat dissipation fan, gas exchange between the gas in the heat dissipation cavity and the outside gas is carried out, facilitating overall heat dissipation.

[0021] 2. A first delay magnet and a second delay magnet are provided. When the sliding plate moves such that the first delay magnet moves towards the second delay magnet, the magnetic force between the first delay magnet and the second delay magnet facilitates the movement of the sliding plate.

Detailed Embodiment

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] An embodiment of the present application discloses a dust-proof high and low voltage switch cabinet. Referring to Figure 1 , it includes a cabinet body 1. The cabinet body 1 is provided with an installation cavity 2. The top of the cabinet body 1 is provided with a heat dissipation seat 3. The heat dissipation seat 3 is provided with a heat dissipation cavity 5. The heat dissipation cavity 5 communicates with the installation cavity 2. The heat dissipation seat 3 is provided with a circulation hole 4. The circulation hole 4 is located at the top of the heat dissipation seat 3. The circulation hole 4 is used to communicate the outside with the heat dissipation cavity 5.

[0030] The wall of the heat dissipation cavity 5 is provided with a partition plate 6. The partition plate 6 divides the heat dissipation cavity 5 into a heat dissipation area 7 and a communication area 8. The communication area 8 is located on the side of the partition plate 6 away from the installation cavity 2. The partition plate 6 is provided with a heat dissipation fan 9. The heat dissipation fan 9 is located at one end of the partition plate 6 close to the installation cavity 2. The partition plate 6 is provided with a first heat dissipation hole 10. The first heat dissipation hole 10 penetrates through the partition plate 6. The penetration direction of the first heat dissipation hole 10 is the vertical direction.

[0031] The side wall of the heat dissipation area 7 is provided with a sliding groove 11. The extending direction of the sliding groove 11 is the horizontal direction. The bottom of the sliding groove 11 is provided with a heat expansion block 13. One end of the heat expansion block 13 away from the bottom of the sliding groove 11 is provided with a connecting spring 12. The connecting spring 12 is connected with a sliding plate 14. The sliding plate 14 is located at one end of the connecting spring 12 away from the heat expansion block 13. The elastic force of the connecting spring 12 limits the distance between the sliding plate 14 and the heat expansion block 13 from decreasing. The sliding plate 14 slides on the wall of the sliding groove 11. The sliding plate 14 is provided with a second heat dissipation hole 15. The second heat dissipation hole 15 penetrates through the sliding plate 14. The second heat dissipation hole 15 is used to communicate with the first heat dissipation hole 10.

[0032] One end of the sliding plate 14 away from the connecting spring 12 is provided with a delay member 16. The delay member 16 is used to limit the sliding plate 14 from moving towards the direction close to the bottom of the sliding groove 11. In the present application, the delay member 16 includes a delay spring 161, a first delay magnet 162 and a second delay magnet 163. The delay spring 161 is located at one end of the sliding plate 14 away from the connecting spring 12. The delay spring 161 is connected with the first delay magnet 162. The wall of the heat dissipation cavity 5 is provided with a relief groove 17. The second delay magnet 163 is located at the bottom of the relief groove 17. The magnetic forces of the first delay magnet 162 and the second delay magnet 163 attract each other;

[0033] When the heat-expandable block 13 expands upon heating and compresses the connecting spring 12, the connecting spring 12 causes the sliding plate 14 to tend to move away from the bottom of the sliding groove 11. The movement of the sliding plate 14 causes the first delay magnet 162 to move towards the second delay magnet 163. The magnetic force of the first delay magnet 162 and the magnetic force of the second delay magnet 163 cause the first delay magnet 162 to move towards the second delay magnet 163. The delay spring 161 pulls the sliding plate 14 towards the second delay magnet 163. As the sliding plate 14 moves, the first heat dissipation hole 10 communicates with the second heat dissipation hole 15. At this time, the outside, the communication area 8 and the heat dissipation area 7 are in communication, and the heat dissipation effect of the heat dissipation fan 9 increases. When the temperature of the heat dissipation cavity 5 decreases, the heat-expandable block 13 contracts, causing the sliding plate 14 to move towards the bottom of the sliding groove 11. At this time, since the first delay magnet and the second delay magnet are linked, the delay spring 161 plays a role in restricting the sliding plate 14 from moving towards the bottom of the sliding groove 11, reducing the situation where the sliding plate 14 moves back and forth due to temperature changes.

[0034] In actual use, a dust-proof structure such as a dust-proof net can be provided on the top of the heat dissipation base 3 to reduce the entry of dust when the first heat dissipation hole 10 communicates with the second heat dissipation hole 15. Secondly, the top of the heat dissipation base 3 needs to be cleaned regularly to reduce dust.

[0035] The partition plate 6 is provided with heat dissipation ridges 18. The heat dissipation ridges 18 are located on the side of the partition plate 6 facing away from the heat dissipation area 7. There are multiple heat dissipation ridges 18, and the heat dissipation ridges 18 are evenly spaced. There are heat dissipation grooves 19 left between adjacent heat dissipation ridges 18. The first heat dissipation hole 10 is located at the bottom of the heat dissipation groove 19.

[0036] The partition plate 6 is provided with a linkage groove 20. The linkage groove 20 is located on the side of the partition plate 6 close to the sliding plate 14. The sliding plate 14 is provided with a strip-shaped hole 21. The strip-shaped hole 21 communicates with the linkage groove 20. At the bottom of the linkage groove 20, there is a linkage spring 22. One end of the linkage spring 22 away from the bottom of the linkage groove 20 is provided with a linkage block 23. The linkage block 23 is embedded in the strip-shaped hole 21. The elastic force of the linkage spring 22 restricts the linkage block 23 from moving towards the bottom of the linkage groove 20.

[0037] The linkage block 23 is provided with an inclined surface 24. The inclined surface 24 is located at one end of the linkage block 23 away from the bottom of the linkage groove 20. The linkage block 23 extends along the direction away from the bottom of the sliding groove 11 towards the direction away from the bottom of the linkage groove 20. The inclined surface 24 is used to abut against the wall of the strip-shaped hole 21. The partition plate 6 is provided with a linkage hole 25. The linkage hole 25 is located at one end of the partition plate 6 away from the linkage groove 20. The linkage hole 25 penetrates through the partition plate 6 to the linkage groove 20. The linkage block 23 is connected with a control rod 27. The control rod 27 passes through the linkage hole 25.

[0038] The heat dissipation cavity 5 is provided with a control groove 28, and the control groove 28 is provided with a sliding rod 29 and a driving member. The sliding rod 29 slides in the control groove 28, and the sliding direction of the sliding rod 29 is the extending direction of the heat dissipation rib 18. The driving member is used to drive the sliding rod 29 to slide. In actual use, the driving member can be a cylinder. Alternatively, the driving member can also be an oil cylinder.

[0039] The sliding rod 29 is provided with an air extraction member 26, and the air extraction member 26 is used to adsorb dust between adjacent heat dissipation ribs 18. The heat dissipation cavity 5 is provided with a contact sensor 30. The contact sensor 30 is located on the side of the control rod 27 away from the linkage block 23. The contact sensor 30 is electrically connected to the driving member, and the contact sensor 30 is used to abut against the control rod 27.

[0040] When the sliding plate 14 moves in a direction away from the bottom of the sliding groove 11, the inclined surface 24 of the linkage block 23 abuts against the wall of the strip-shaped hole 21. The movement of the sliding plate 14 causes the linkage block 23 to move in a direction close to the bottom of the linkage groove 20 and causes the control rod 27 to move. When the control rod 27 moves and abuts against the contact sensor 30, the contact sensor 30 sends a signal and causes the driving member to drive the sliding rod 29 to move.

[0041] The implementation principle of a dust-proof high and low voltage switch cabinet in an embodiment of the present application is as follows: In actual use, the heat dissipation fan 9 circulates the gas in the heat dissipation area 7 and the installation cavity 2 and assists in heat dissipation. As the temperature in the heat dissipation area 7 rises, the heat expansion block 13 expands due to heat and compresses the connecting spring 12. The connecting spring 12 causes the sliding plate 14 to have a tendency to move away from the bottom of the sliding groove 11. When the sliding plate 14 moves in a direction away from the bottom of the sliding groove 11, the inclined surface 24 of the linkage block 23 abuts against the wall of the strip-shaped hole 21. The movement of the sliding plate 14 causes the sliding block and the control block to move and abut against the contact sensor 30. The contact sensor 30 causes the driving member to control the movement of the sliding rod 29 and causes the air extraction member 26 to perform an air extraction operation.

[0042] As the sliding plate 14 continues to move, the magnetic force of the delay magnet one 162 and the magnetic force of the delay magnet two 163 cause the delay magnet one 162 to move in a direction close to the delay magnet two 163. The delay spring 161 pulls the sliding plate 14 to move in a direction close to the delay magnet two 163, and the heat dissipation hole one 10 communicates with the heat dissipation hole two 15.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
