[0002] AC low-voltage distribution cabinets are applicable to the power distribution systems of power users such as power plants, substations, factories and mines, with an AC frequency of 50 Hz, a rated working voltage of 380 V, and a rated working current up to 3150 A, and are used for the power conversion, distribution and control of power, lighting and distribution equipment.
[0003] During the use of existing AC low-voltage distribution cabinets, the internal electrical components generate heat during operation, so heat dissipation treatment is required inside them. Conventional heat dissipation methods are all to add cooling fans inside the AC low-voltage distribution cabinets to accelerate the gas flow inside the cabinet. However, the acceleration effect brought by a single cooling fan is relatively weak and cannot well accelerate the hot gas inside the cabinet, resulting in poor heat dissipation effect and low use value of existing AC low-voltage distribution cabinets. Summary of the Invention
[0004] The present invention discloses an AC low-voltage distribution cabinet with accelerated internal gas flow guiding, aiming to solve the technical problem that during the use of existing AC low-voltage distribution cabinets, the internal electrical components generate heat during operation, so heat dissipation treatment is required inside them. Conventional heat dissipation methods are all to add cooling fans inside the AC low-voltage distribution cabinets to accelerate the gas flow inside the cabinet. However, the acceleration effect brought by a single cooling fan is relatively weak and cannot well accelerate the hot gas inside the cabinet, resulting in poor heat dissipation effect of existing AC low-voltage distribution cabinets.
[0005] To achieve the above object, the present invention adopts the following technical solutions:
[0006] An AC low-voltage power distribution cabinet with internal gas acceleration and diversion, including a cabinet body. The bottom inner wall of the cabinet body is fixedly connected with two lifting guide rails, and lifting sliders are slidably connected inside both of the two lifting guide rails. A gas acceleration and flow component is arranged on the same side of the two lifting sliders. The gas acceleration and flow component includes a semi-enclosed ring pipe, and the semi-enclosed ring pipe is fixedly connected to the outer side walls of the two lifting sliders. An intermediate partition is fixedly connected inside the semi-enclosed ring pipe. An air extraction hole is opened on the outer side wall of the semi-enclosed ring pipe facing downward, and diversion holes are opened on both side walls of the semi-enclosed ring pipe facing the center of the cabinet body. Diversion pipes are fixedly connected inside both of the two diversion holes. The opening ends of both of the two diversion pipes are fixedly connected with a communicating hollow arc plate. Connecting holes are equidistantly opened on the outer side wall of the communicating hollow arc plate facing obliquely downward. An air extraction hose is fixedly connected inside each connecting hole. A plurality of air blowing holes are opened on the outer side wall of the semi-enclosed ring pipe facing upward, and an air blowing pipe is fixedly connected inside each air blowing hole. A pump ring frame two is fixedly connected to one side of each of the two lifting sliders, and an air pump two is fixedly connected inside both of the two pump ring frames two. The air extraction end of the air pump two is fixedly connected with an air extraction pipe, and one end of the air extraction pipe is inserted into the inside of the semi-enclosed ring pipe below the intermediate partition. The air delivery end of the air pump two is fixedly connected with an air delivery pipe, and one end of the air delivery pipe is inserted into the inside of the semi-enclosed ring pipe above the intermediate partition.
[0007] By arranging the gas acceleration and flow component, when heat dissipation treatment is carried out inside the cabinet body, the hydraulic cylinder is adjusted to drive the semi-enclosed ring pipe to move from bottom to top. During the upward movement of the semi-enclosed ring pipe, the air pump two is started. The air pump two pumps the hot gas located below the semi-enclosed ring pipe into the semi-enclosed ring pipe, and then sprays it out through the air blowing pipe. The sprayed hot gas drives the hot gas above to flow rapidly upward. When the hot gas below is evacuated, the air pressure in the lower space drops, and then the air intake component quickly replenishes the gas. The replenished gas is cold gas. As the semi-enclosed ring pipe rises, part of the cold gas is evacuated to quickly push the hot gas, further improving the discharge speed of the hot gas, accelerating the exchange of hot and cold gases, and improving the heat dissipation effect of the cabinet body.

[0011] By providing the exhaust assembly, when the gas inside the cabinet impacts the sealing plate, the connecting spring rods are stretched passively, and the hot gas gradually passes through the exhaust holes and is discharged. After the hot gas inside the cabinet is discharged, the second air pump stops operating, and the connecting spring rods drive the sealing plate to reset and block the exhaust holes, preventing external gas from carrying impurities from entering the cabinet through the upper exhaust holes and causing pollution inside the cabinet.
[0012] In a preferred embodiment, limiting rails are fixedly connected to the tops of both ends of the cabinet body where the sealing plate is located, and limiting sliders are slidably connected to the interiors of the two limiting rails. The two limiting sliders are fixedly connected to both sides of the sealing plate.

The air intake assembly includes a mounting circular frame, and the mounting circular frame is fixedly connected to the outside of the cabinet body where the air intake holes are located.
[0015] By providing the air intake assembly, when the air pressure inside the cabinet decreases, the first air pump is started, and the first air pump introduces external gas into the regional air guiding frame. The second driving motor is started, and the second driving motor drives the regional air guiding frame to rotate, so that the gas gradually passes through the filter screen, accelerating the filling of the gas and improving the utilization rate of each position of the filter screen.
[0016] In a preferred embodiment, an inner mounting ring is fixedly connected to the inner side wall of the mounting circular frame close to the air intake hole, and a filter screen is fixedly connected to the inside of the inner mounting ring. An external connecting rod is fixedly connected to the outer side wall of the mounting circular frame, and one end of the external connecting rod is fixedly connected to a motor bracket.
[0017] In a preferred embodiment, a driving motor II is fixedly connected inside the motor frame, and the output shaft of the driving motor II is fixedly connected with a rotating long shaft through a coupling. One end of the rotating long shaft is fixedly connected with a regional air guide frame. There is a gap between the regional air guide frame and the filter screen. Scrapers are fixedly connected to both side walls of the regional air guide frame, and the scrapers are in contact with the filter screen.
[0018] In a preferred embodiment, mounting ring plates are fixedly connected to the outer side wall of the rotating long shaft, and two pump ring frames I are fixedly connected to the outer side wall of the mounting ring plate. An air pump I is fixedly connected inside one of the pump ring frames I. The air delivery end of the air pump I is connected to the inside of the regional air guide frame through a pipeline. A dust suction pump is fixedly connected inside the other pump ring frame I. Dust collection covers are fixedly connected to both sides of the regional air guide frame above the scrapers. Dust collection holes are equidistantly formed on the inner side walls of the two dust collection covers facing the filter screen. Communication holes are formed on the same side of the two dust collection covers, and the same communication pipe is fixedly connected inside the two communication holes.

The dust suction end of the dust suction pump is fixedly connected with a dust collection pipe, and one end of the dust collection pipe is inserted into the inside of the communication pipe. The dust conveying end of the dust suction pump is connected to the inside of the dust collection box through a pipeline.
[0019] As can be seen from the above, an AC low-voltage power distribution cabinet with internal gas acceleration and diversion provided by the present invention has the technical effect that when performing heat dissipation treatment inside the cabinet body, the adjusting hydraulic cylinder drives the semi-enclosing ring pipe to move from bottom to top. During the upward movement of the semi-enclosing ring pipe, the air pump II is started. The air pump II pumps the hot gas located below the semi-enclosing ring pipe into the semi-enclosing ring pipe, and then sprays it out through the blowing pipe. The sprayed hot gas drives the hot gas above to flow rapidly upward. When the hot gas below is evacuated, the air pressure at the lower space drops, and then the air intake assembly quickly replenishes the gas. The replenished gas is cold gas. As the semi-enclosing ring pipe rises, part of the cold gas is evacuated to quickly push the hot gas, further improving the discharge speed of the hot gas and accelerating the exchange of hot and cold gases.

Detailed implementation manners
[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0030] An AC low-voltage power distribution cabinet with internal gas acceleration and diversion disclosed by the present invention is mainly applied to the existing AC low-voltage power distribution cabinet. During its use, the electrical components inside it will generate heat during operation. Therefore, heat dissipation treatment needs to be carried out inside it. The conventional heat dissipation methods are all to add heat dissipation fans inside the AC low-voltage power distribution cabinet to accelerate the gas flow inside the cabinet body. However, the acceleration effect brought by a single heat dissipation fan is relatively weak, and it cannot well accelerate the hot gas inside the cabinet body, resulting in a poor heat dissipation effect of the existing AC low-voltage power distribution cabinet.
[0031] Referring to Figures 1 - 8 , an AC low-voltage power distribution cabinet with internal gas acceleration and diversion, includes a cabinet body 1. Two lifting guide rails 5 are fixedly connected to the bottom inner wall of the cabinet body 1, and lifting sliders 7 are slidably connected inside both of the two lifting guide rails 5. A gas acceleration and flow component 8 is arranged on the same side of the two lifting sliders 7. The gas acceleration and flow component 8 includes a semi-enclosing ring pipe 801, and the semi-enclosing ring pipe 801 is fixedly connected to the outer side walls of the two lifting sliders 7. An intermediate partition 809 is fixedly connected inside the semi-enclosing ring pipe 801. Air extraction holes 811 are formed on the outer side wall of the semi-enclosing ring pipe 801 facing downward, and diversion holes are formed on both side walls of the semi-enclosing ring pipe 801 facing the center of the cabinet body 1. Flow diversion pipes 805 are fixedly connected inside both of the two diversion holes. The open ends of both of the two flow diversion pipes 805 are fixedly connected with a communicating hollow arc plate 804. Connection holes are equidistantly formed on the outer side wall of the communicating hollow arc plate 804 facing obliquely downward. An air extraction hose 810 is fixedly connected inside each connection hole. A plurality of air blowing holes are formed on the outer side wall of the semi-enclosing ring pipe 801 facing upward, and an air blowing pipe 802 is fixedly connected inside each air blowing hole. A pump ring frame two 803 is fixedly connected to one side of each of the two lifting sliders 7, and an air pump two 808 is fixedly connected inside both of the two pump ring frame two 803. The air extraction end of the air pump two 808 is fixedly connected with an air extraction pipe 806, and one end of the air extraction pipe 806 is inserted into the inside of the semi-enclosing ring pipe 801 below the intermediate partition 809. The air delivery end of the air pump two 808 is fixedly connected with an air delivery pipe 807, and one end of the air delivery pipe 807 is inserted into the inside of the semi-enclosing ring pipe 801 above the intermediate partition 809.
[0032] In a specific application scenario, when heat dissipation treatment is carried out inside the cabinet body 1, the adjusting hydraulic cylinder 6 drives the semi-surrounding ring pipe 801 to move upward from bottom to top. During the upward movement of the semi-surrounding ring pipe 801, the air pump two 808 is started. The air pump two 808 sucks the hot gas located below the semi-surrounding ring pipe 801 into the semi-surrounding ring pipe 801, and then sprays it out through the air blowing pipe 802. The sprayed hot gas drives the hot gas above to flow rapidly upward. When the hot gas below is evacuated, the air pressure in the lower space drops, and then the air intake assembly 4 quickly replenishes the gas. The replenished gas is cold gas. As the semi-surrounding ring pipe 801 rises, part of the cold gas is evacuated to quickly push the hot gas, further increasing the speed of the hot gas discharge, accelerating the exchange of hot and cold gases, and improving the heat dissipation effect of the cabinet body 1.
[0033] Specifically, during the process of the hydraulic cylinder 6 driving the semi-surrounding ring pipe 801 to rise, the air extraction hose 810 gradually contacts the electrical components inside the cabinet body 1 or is inserted into the gaps between the electrical components. The hot gas near the electrical components is extracted through the air extraction hose 810, and then the cold gas can be filled, further improving the heat dissipation effect of the cabinet body 1.
[0034] Refer to Figure 1 、 Figure 2 and Figure 3 In a preferred embodiment, hydraulic cylinders 6 are fixedly connected to the top inner walls of the cabinet body 1 near the two lifting guide rails 5, and the output ends of the two hydraulic cylinders 6 are respectively fixedly connected to the tops of the adjacent lifting sliders 7. A door hole is opened on one side of the cabinet body 1, and a cabinet door 3 is hinged inside the door hole. Installation rods 9 are fixedly connected to one side of the two lifting sliders 7 near the bottom ends, and an installation collar 10 is fixedly connected to the end of the installation rod 9. A pressure sensor 11 is fixedly connected inside the installation collar 10.
[0035] Refer to Figure 1 、 Figure 2 and Figure 6 , in a preferred embodiment, an exhaust hole is provided at the top of the cabinet body 1, and an exhaust assembly 2 is provided at the exhaust hole. The exhaust assembly 2 includes a sealing plate 201. Two hanging brackets 204 are fixedly connected to the inner wall of the top of the cabinet body 1 below the exhaust hole. On the sides of the two hanging brackets 204 facing the sealing plate 201, connecting spring rods 206 are fixedly connected at equal intervals. The top ends of the connecting spring rods 206 are fixedly connected to the bottom of the sealing plate 201. Limit rails 205 are fixedly connected to the top of the cabinet body 1 at both ends of the sealing plate 201, and limit sliders 207 are slidably connected to the interiors of the two limit rails 205. The two limit sliders 207 are fixedly connected to both sides of the sealing plate 201. Inner plates 208 are fixedly connected to the inner side walls of the two limit rails 205 above the limit sliders 207. Pressure sensors 209 are fixedly connected to the bottoms of the two inner plates 208. The outer side walls of the two limit rails 205 are fixedly connected to the same mounting bracket 203, and a driving motor 210 is fixedly connected to the top of the mounting bracket 203. The output shaft of the driving motor 210 is fixedly connected to a driving shaft 211 through a coupling. Accelerating rotating blades 202 are annularly distributed on the outer side wall of the driving shaft 211.
[0036] Specifically, when the gas inside the cabinet body 1 impacts the sealing plate 201, the connecting spring rods 206 are stretched passively, and the hot gas gradually passes through the exhaust hole and is discharged. After the hot gas inside the cabinet body 1 is discharged, the air pump two 808 stops operating, and then the connecting spring rods 206 drive the sealing plate 201 to reset and block the exhaust hole, preventing the outside gas from carrying impurities from entering the cabinet body 1 through the upper exhaust hole and causing pollution inside the cabinet body 1.
[0037] It should be noted that after the sealing plate 201 rises passively and contacts the pressure sensor 209, the driving motor 210 drives the accelerating rotating blades 202 to rotate, and the accelerating rotating blades 202 quickly take away the discharged hot gas from the sealing plate 201, preventing this part of the hot gas from re-entering the cabinet body 1.
[0038] Refer to Figure 1 、 Figure 2 、 Figure 7 and Figure 8, in a preferred embodiment, air inlet holes are provided on both sides of the cabinet body 1, and an air inlet assembly 4 is provided at the air inlet holes of the cabinet body 1. The air inlet assembly 4 includes an installation round frame 402, and the installation round frame 402 is fixedly connected to the outside of the cabinet body 1 at the air inlet hole. The inner side wall of the installation round frame 402 close to the air inlet hole is fixedly connected with an inner installation ring 404, and a filter screen 401 is fixedly connected to the inside of the inner installation ring 404. The outer side wall of the installation round frame 402 is fixedly connected with an external connection rod 403. One end of the external connection rod 403 is fixedly connected with a motor frame 407, and a driving motor two 406 is fixedly connected to the inside of the motor frame 407. The output shaft of the driving motor two 406 is fixedly connected with a rotating long shaft 417 through a coupling. One end of the rotating long shaft 417 is fixedly connected with a regional air guiding frame 405. There is a gap between the regional air guiding frame 405 and the filter screen 401. Scraper blades 414 are fixedly connected to both side walls of the regional air guiding frame 405, and the scraper blades 414 are in contact with the filter screen 401. An installation ring plate 410 is fixedly connected to the outer side wall of the rotating long shaft 417, and two pump ring frames one 409 are fixedly connected to the outer side wall of the installation ring plate 410. An air pump one 411 is fixedly connected to the inside of one of the pump ring frames one 409. The air delivery end of the air pump one 411 is connected to the inside of the regional air guiding frame 405 through a pipeline. A dust suction pump 418 is fixedly connected to the inside of the other pump ring frame one 409. Dust collection covers 412 are fixedly connected to both sides of the regional air guiding frame 405 above the scraper blades 414. Dust collection holes 413 are equidistantly provided on the inner side walls of the two dust collection covers 412 facing the filter screen 401. Communication holes are provided on the same side of the two dust collection covers 412, and the same communication pipe 415 is fixedly connected to the inside of the two communication holes. A dust collection box 408 is fixedly connected to one side of the installation ring plate 410. The dust suction end of the dust suction pump 418 is fixedly connected with a dust collection pipe 416. One end of the dust collection pipe 416 is inserted into the inside of the communication pipe 415, and the dust conveying end of the dust suction pump 418 is connected to the inside of the dust collection box 408 through a pipeline.
[0039] Specifically, when the air pressure inside the cabinet body 1 decreases, the air pump one 411 is started. The air pump one 411 introduces external gas into the regional air guiding frame 405. The driving motor two 406 is started, and the driving motor two 406 drives the regional air guiding frame 405 to rotate, so that the gas gradually passes through the filter screen 401, accelerating the filling of the gas and improving the utilization rate of each position of the filter screen 401.
[0040] It should be noted that when the driving motor two 406 drives the regional air guiding frame 405 to rotate, the scraper blades 414 scrape off the dust attached to the filter screen 401. The dust suction pump 418 is started, and the dust suction pump 418 collects the scattered dust through the dust collection holes 413 on the dust collection covers 412, avoiding the blockage of the filter holes on the filter screen 401 by the dust carried by the gas and improving the service life of the filter screen 401.
[0041] Working principle: Every time the electrical components inside the cabinet body 1 work for a period of time, the adjusting hydraulic cylinder 6 drives the semi-surrounding ring pipe 801 to move upward from bottom to top. During the upward movement of the semi-surrounding ring pipe 801, the second air pump 808 is started. The second air pump 808 sucks the hot gas located below the semi-surrounding ring pipe 801 into the semi-surrounding ring pipe 801 and then sprays it out through the air blowing pipe 802. The sprayed hot gas drives the hot gas above to flow rapidly upward. When the hot gas below is sucked away, the air pressure in the lower space drops. After the air pressure sensor 11 detects that the air pressure value in the lower part of the space inside the cabinet body 1 reaches the specified point, the first air pump 411 is started. The first air pump 411 introduces the external gas into the regional air guiding frame 405, and the second driving motor 406 is started. The second driving motor 406 drives the regional air guiding frame 405 to rotate, so that the gas gradually passes through the filter screen 401 to accelerate the filling of the gas. As the cold gas gradually enters the cabinet body 1, the hot gas gradually accumulates in the upper space of the cabinet body 1. Then this part of the hot gas impacts the blocking plate 201, and the connecting spring rod 206 is stretched passively. The hot gas gradually passes through the exhaust holes and is discharged. After the hot gas inside the cabinet body 1 is discharged, the second air pump 808 stops operating. Then the connecting spring rod 206 drives the blocking plate 201 to reset and block the exhaust holes, ending a single heat dissipation operation.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
