However, the acceleration effect brought by a single cooling fan is relatively weak, and it is not possible to achieve a good acceleration of the hot gas inside the cabinet, resulting in poor heat dissipation effect of the existing AC low-voltage distribution cabinet and low use value. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0029] An AC low-voltage distribution cabinet with internal gas acceleration and flow guidance disclosed in the present invention is mainly applied to existing AC low-voltage distribution cabinets. During use, the internal electrical components of the cabinets will generate heat during operation, so heat dissipation treatment is required. Conventional heat dissipation methods are to add a cooling fan inside the AC low-voltage distribution cabinet to accelerate the gas flow inside the cabinet. However, the acceleration effect brought by a single cooling fan is relatively weak, and it is not possible to achieve good acceleration of the hot gas inside the cabinet, which leads to a scenario in which the existing AC low-voltage distribution cabinet has a poor heat dissipation effect.

[0031] In a specific application scenario, when performing heat dissipation treatment inside the cabinet 1, the hydraulic cylinder 6 is adjusted to drive the semi-enclosed annular tube 801 to move from bottom to top. During the rising process of the semi-enclosed annular tube 801, the air pump 808 is started. The air pump 808 draws the hot gas below the semi-enclosed annular tube 801 into the semi-enclosed annular tube 801, and then sprays it out through the blowing pipe 802. The sprayed hot gas drives the hot gas above to flow rapidly upward. When the hot gas below is extracted, the air pressure in the lower space drops, and the air intake component 4 quickly replenishes the gas, which is replenished with cold gas. As the semi-enclosed annular tube 801 rises, part of the cold gas is extracted to quickly push the hot gas, further increasing the speed of hot gas discharge, accelerating the exchange of hot and cold gases, and improving the heat dissipation effect of the cabinet 1.
[0032] Specifically, when the hydraulic cylinder 6 drives the semi-enclosed ring tube 801 to rise, the exhaust hose 810 gradually contacts the electrical components inside the cabinet 1 or gets stuck in the gaps between the electrical components. The hot gas near the electrical components is extracted through the exhaust hose 810, and cold gas can be filled in, further improving the heat dissipation effect of the cabinet 1.
[0033] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a hydraulic cylinder 6 is fixedly connected to the top inner wall 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 adjacent lifting sliders 7.

[0035] Specifically, when the gas inside the cabinet 1 impacts the sealing plate 201, the connecting spring rod 206 is passively stretched, and the hot gas is gradually discharged through the exhaust hole. When the hot gas inside the cabinet 1 is discharged, the air pump 2 808 stops running, and the connecting spring rod 206 drives the sealing plate 201 to reset and block the exhaust hole, thereby preventing the external gas from carrying impurities into the cabinet 1 from the exhaust hole above and causing internal pollution of the cabinet 1.
[0036] It should be noted that after the blocking plate 201 passively rises and contacts the pressure sensor 209, the driving motor 210 drives the acceleration blade 202 to rotate, and the exhaust hot gas is quickly taken away from the blocking plate 201 by the acceleration blade 202, so as to prevent this part of the hot gas from re-entering the cabinet 1.
[0037] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8In a preferred embodiment, air inlet holes are opened on both sides of the cabinet 1, and the cabinet 1 is provided with an air inlet assembly 4 at the air inlet hole, and the air inlet assembly 4 includes a mounting circular frame 402, the mounting circular frame 402 is fixedly connected to the cabinet 1 at the outside of the air inlet hole, the inner side wall of the mounting circular frame 402 close to the air inlet hole is fixedly connected to an inner mounting ring 404, and the inner part of the inner mounting ring 404 is fixedly connected to a filter screen 401, and the outer side wall of the mounting circular frame 402 is fixedly connected to an external rod 403, and the external rod 404 is fixedly connected to the outer side wall of the mounting circular frame 402. One end of 03 is fixedly connected to a motor frame 407, and the interior of the motor frame 407 is fixedly connected to a driving motor 2 406, and the output shaft of the driving motor 2 406 is fixedly connected to a rotating long shaft 417 through a coupling, and one end of the rotating long shaft 417 is fixedly connected to a regional air guide frame 405, and there is a gap between the regional air guide frame 405 and the filter 401, and the two side walls of the regional air guide frame 405 are fixedly connected to scrapers 414, and the scrapers 414 are in contact with the filter 401, and the rotating long shaft 41 The outer wall of the mounting ring plate 410 is fixedly connected to the outer wall of the mounting ring plate 410, and two pump ring frames 409 are fixedly connected to the inner part of one pump ring frame 409, and an air pump 411 is fixedly connected to the inner part of the regional air guide frame 405 through a pipeline, and a dust suction pump 418 is fixedly connected to the inner part of the other pump ring frame 409, and both sides of the regional air guide frame 405 above the scraper 414 are fixedly connected to dust collecting covers 412, and the two dust collecting covers are fixedly connected to the outer wall of the mounting ring plate 410. Dust collecting holes 413 are equidistantly provided on the inner wall of the cover 412 facing the filter 401, and connecting holes are provided on the same side of the two dust collecting covers 412. The inside of the two connecting holes is fixedly connected to the same connecting pipe 415, and one side of the mounting ring plate 410 is fixedly connected to the dust collecting box 408, and the dust suction end of the dust suction pump 418 is fixedly connected to the dust collecting pipe 416, and one end of the dust collecting pipe 416 is inserted into the inside of the connecting pipe 415, and the dust delivery end of the dust suction pump 418 is connected to the inside of the dust collecting box 408 through a pipeline.
[0038] Specifically, when the air pressure inside the cabinet 1 decreases, the air pump 411 is started, and the air pump 411 introduces external gas into the regional air guide frame 405, and the driving motor 406 is started, and the driving motor 406 drives the regional air guide frame 405 to rotate, so that the gas gradually passes through the filter 401, accelerates the filling of the gas, and improves the utilization rate of each position of the filter 401.
[0039] It should be noted that when the driving motor 2 406 drives the regional air guide frame 405 to rotate, the scraper 414 scrapes off the dust attached to the filter 401 and starts the dust suction pump 418. The dust suction pump 418 collects the floating dust through the dust collecting holes 413 on the dust cover 412 to prevent the dust carried by the gas from clogging the filter holes on the filter 401, thereby increasing the service life of the filter 401.
[0040] Working principle: after the electrical components inside the cabinet 1 work for a period of time, the hydraulic cylinder 6 is adjusted to drive the semi-enclosed annular tube 801 to move from bottom to top. During the rising process of the semi-enclosed annular tube 801, the air pump 808 is started. The air pump 808 draws the hot gas below the semi-enclosed annular tube 801 into the semi-enclosed annular tube 801, and then ejects it through the air blowing pipe 802. The ejected hot gas drives the hot gas above to flow rapidly upward. When the hot gas below is extracted, the air pressure in the space below drops. After the air pressure sensor 11 detects that the air pressure value inside the lower part of the cabinet 1 is about to reach the specified point, the air pump 411 is started. The air pump 411 will The external gas is introduced into the regional gas guide frame 405, and the driving motor 2 406 is started. The driving motor 2 406 drives the regional gas guide frame 405 to rotate, so that the gas gradually passes through the filter 401, accelerating the filling of the gas. As the cold gas gradually enters the interior of the cabinet 1, the hot gas gradually accumulates in the space above the cabinet 1. Then, this part of the hot gas impacts the sealing plate 201, and the connecting spring rod 206 is passively stretched, and the hot gas gradually passes through the exhaust hole and is discharged. When the hot gas inside the cabinet 1 is discharged, the air pump 2 808 stops running, and the connecting spring rod 206 drives the sealing plate 201 to reset to block the exhaust hole, thereby ending a single heat dissipation operation.
