Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a safe power distribution cabinet capable of autonomously dissipating heat and cooling. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. 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 used in occasions where the load is relatively dispersed and there are fewer 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] For example, the invention with publication number CN112038953B discloses an autonomous rainproof heat dissipation distribution cabinet. The invention is provided with heat dissipation holes, heat sinks, a first heat dissipation fan, a protective shell and a second heat dissipation fan to form a negative pressure air duct. Cold air under negative pressure can be sucked into the inside of the distribution cabinet shell through the heat dissipation holes, accelerating the conversion of gas inside the distribution cabinet shell. The heat sink accelerates the heat dissipation inside the distribution cabinet shell, ensuring the normal use of the main body of the electrical parts inside the distribution cabinet shell and extending the service life. However, in actual use, when encountering a relatively humid environment on rainy days, some water vapor will also enter the inside of the distribution cabinet through the heat dissipation holes, causing problems affecting the service life and safety of internal electronic components.

[0016] The present invention provides a safe power distribution cabinet capable of autonomous heat dissipation and temperature reduction, which has the following beneficial effects: 1. During the use of the present invention, after the cabinet door is closed, the entire interior of the equipment is sealed, so that external water vapor and dust cannot enter the interior of the cabinet, avoiding interference with the internal electronic devices, which is beneficial to improving the safety during use. During use, the dual-axis motor will drive the driven gear to rotate through the active gear, so that the two fans on the fan shaft rotate at the same time. Therefore, during use, the lower fan blades can send the airflow inside the heat exchange box into the shunt pipe, and blow it to the electrical components from the air blowing pipe. At the same time, since the air blowing pipes are equidistantly arranged inside the cabinet and are close to the mounting frame, the heat exchange of electrical components in various places can be uniform. Compared with the existing distribution cabinet, due to the single airflow flow channel during use, when the airflow carries heat to the air outlet position , which will make the temperature near the air outlet higher, and the present device can evenly exchange heat for the electrical components on the mounting frame, thereby improving the cooling effect, and the airflow after heat exchange can flow into the heat exchange box through the return pipe. At this time, the heat exchange plate is used to cool the airflow while guiding the airflow to extend its stroke inside the heat exchange box, thereby improving the heat exchange effect, and the airflow inside the cabinet can be circulated to dissipate heat and cool down the cabinet. In this process, the fan blades on the top of the fan shaft will also drive the airflow on the upper part of the fixed box, and the external air will enter the upper end of the heat exchange box under the filtration of the dustproof mesh plate. At this time, the heat sink is used to improve the heat dissipation and cooling effect of the hot end of the semiconductor refrigeration plate, and then the airflow is discharged from the upper end of the fixed box, which can also automatically dissipate heat for the semiconductor refrigeration plate.

[0017] 2. The dual-axis motor of the present invention will also drive the rotating plate to rotate through the reducer. At this time, since the cabinet will limit the moving direction of the synchronization rod, the rotating plate will reciprocately push and pull the limit plate through the sliding column, so that the synchronization rod drives the driving column to move up and down reciprocatingly, thereby driving the air blowing pipe to reciprocate through the driving plate. Therefore, during use, the angle of the air blowing pipe when it is out of the air can be automatically adjusted, so that the air flow is more evenly distributed during the reciprocating rotation process, thereby improving the effect of uniformly cooling the electrical components on the mounting frame.

[0018] 3. During operation, the fan shaft of the present invention will also drive the cam to rotate. At this time, the spring seat will push the piston rod to make the roller fit with the cam. Therefore, when the concave part of the cam is aligned with the roller, the spring seat will drive the piston rod to move, and the water in the water tank can be sucked into the fixed cylinder through the first one-way valve. After that, when the convex part of the cam squeezes the roller, the piston rod can squeeze the water inside the fixed cylinder from the second one-way valve into the spray pipe, and the water mist is sprayed out and attached to the hot end of the heat sink and the semiconductor refrigeration plate. At this time, the evaporation of water is used to absorb heat to further improve the heat dissipation and cooling effect of the semiconductor refrigeration plate. The damper in the spring seat is used to delay the reset time of the spring, so that when the fan shaft rotates at high speed, the roller cannot move to the recessed part of the cam due to the delay. The roller can only move to the recessed part of the cam when the speed is reduced. Therefore, it is only necessary to control the speed of the dual-axis motor to switch the working state of the heat absorption component according to needs, which is more convenient and avoids excessive waste caused by continuous spraying of water mist. The water tank is arranged on the top of the heat sink, so the heat conduction plate can also be used to absorb part of the heat during use, thereby further improving the heat dissipation performance of the semiconductor refrigeration plate.

[0019] 4. When the present invention encounters a rainy environment, rainwater can pass through the barrier net and enter the collecting plate. The collecting plate is V-shaped, which will guide the rainwater and concentrate it in the middle. When a certain amount of rainwater accumulates on the collecting plate, the weight of the collecting plate will be greater than the supporting force of the compression spring. At this time, the collecting plate will slide down, so that the sealing plug is separated from the liquid inlet, so that the rainwater on the top of the collecting plate flows to the filter plate through the liquid inlet, and flows to the lower part of the water tank for collection after being filtered by the filter plate, so as to collect and utilize the rainwater. When the top of the collecting plate becomes lighter, the compression spring will push the collecting plate under the limit of the sliding rod and the filter plate, so that the sealing plug blocks the liquid inlet, thereby automatically sealing the water tank to prevent excessive loss of water inside the water tank due to natural evaporation.

[0023] See also Figures 1 to 5 , the other end of the dual-axis motor 303 is connected to an adjustment component 4, the adjustment component 4 includes a reducer 401, a rotating plate 402, a sliding column 403 and a limit plate 404, the other end of the dual-axis motor 303 is connected to a reducer 401, and the lower end of the reducer 401 is connected to a rotating plate 402, a sliding column 403 is fixed to one side of the rotating plate 402, and the outer side of the sliding column 403 is slidably connected to the limit plate 404, the adjustment component 4 also includes a synchronization rod 405, a driving column 406 and a driving plate 407, the bottom of the limit plate 404 is fixed with a synchronization rod 405, and driving columns 406 are arranged on both sides of the synchronization rod 405, the outer side of the driving column 406 is slidably connected to the driving plate 407, and the driving plate 407 is fixedly connected to the blowing pipe 308; The specific operation is as follows. First, close the cabinet door of the cabinet body 1. At this time, since the overall interior of the equipment is in a sealed state, water vapor and dust from the outside cannot enter the interior of the cabinet body 1, avoiding interference with the internal electronic components. After that, the biaxial motor 303 drives the driven gear 305 to rotate through the driving gear 304, causing the two fans on the fan shaft 306 to rotate simultaneously. And because the two fan blades are mirror-image arranged, during use, the lower fan blade can send the air flow inside the heat exchange box 310 into the shunt pipe 307 and blow it towards the electrical components from the blow pipe 308. At the same time, since the blow pipes 308 are equidistantly arranged inside the cabinet body 1 and are close to the mounting bracket 2, the cooling effect is improved. During this process, the biaxial motor 303 also drives the rotating plate 402 to rotate through the speed reducer 401. At this time, since the cabinet body 1 restricts the moving direction of the synchronizing rod 405, the rotating plate 402 reciprocally pushes and pulls the limiting plate 404 through the sliding column 403, causing the synchronizing rod 405 to drive the driving column 406 to reciprocally move up and down, thereby driving the blow pipe 308 to reciprocally rotate through the driving plate 407. Therefore, during use, the angle of the blow pipe 308 when discharging air can be automatically adjusted, making the blown air flow more evenly distributed during the reciprocating rotation process. And the air flow after heat exchange inside the cabinet body 1 can enter the return pipe 309 through the openings on both sides and flow to the heat exchange box 310. At this time, while the heat exchange plate 312 cools the air flow, it also guides the air flow, extending its travel inside the heat exchange box 310, and can cycle to dissipate heat from the air flow inside the cabinet body 1. And during this process, the fan blade at the top of the fan shaft 306 also drives the air flow above the fixed box 301, causing a negative pressure to form at the top of the semiconductor refrigeration sheet 311. The outside air will enter the upper end interior of the heat exchange box 310 under the filtration of the dust-proof net plate 314. At this time, the heat sink 313 is used to improve the heat dissipation effect of the hot end of the semiconductor refrigeration sheet 311, and then the air flow is discharged from the upper end of the fixed box 301, thereby automatically dissipating heat from the semiconductor refrigeration sheet 311 as well.

The other end of the piston rod 504 is provided with a spring seat 507. The heat absorption component 5 also includes a first one-way valve 508, a second one-way valve 509 and a spray pipe 510. The top of the fixed cylinder 503 is provided with a first one-way valve 508, and the first one-way valve 508 is connected to the inside of the water tank 501. The end of the fixed cylinder 503 is provided with a second one-way valve 509, and the end of the second one-way valve 509 is provided with a The water tank 501 has a spray pipe 510, and a current collecting assembly 6 is arranged on the top of the water tank 501. The current collecting assembly 6 includes a filter plate 601, a slide bar 602 and a compression spring 603. The filter plate 601 is fixed inside the upper end of the water tank 501, and the four ends of the filter plate 601 are internally slidably connected with the slide bar 602, and the outer side of the slide bar 602 is sleeved with a compression spring 603. The current collecting assembly 6 also includes a current collecting plate 604, a liquid inlet 605 and a sealing plug 606. The top of the compression spring 603 is connected to the current collecting plate 604, and the current collecting plate 604 is connected to the slide bar 603. The rod 602 is fixedly connected, a liquid inlet 605 is opened in the middle of the current collecting plate 604, and a sealing plug 606 is arranged at the upper end of the liquid inlet 605. The current collecting plate 604 is V-shaped, and the current collecting plate 604 is fixedly connected to the sliding rod 602, and the current collecting plate 604 is slidably connected to the water tank 501. The current collecting assembly 6 also includes a fixed rod 607 and a blocking net 608. The bottom of the sealing plug 606 is fixed with a fixed rod 607, and the fixed rod 607 is fixedly connected to the filter plate 601, and the top of the water tank 501 is provided with a blocking net 608; The specific operation is as follows: when the fan shaft 306 is working, due to its fast rotation speed, the damper in the spring seat 507 will delay the reset time of the spring, so that during the high-speed rotation of the fan shaft 306, the roller 505 will not be able to move to the recessed part of the cam 506 due to the delay, and the roller 505 can only move to the recessed part of the cam 506 when the speed is reduced. Therefore, it is only necessary to control the rotation speed of the dual-axis motor 303 to switch the working state of the heat absorption component 5, which is more convenient. The water tank 501 is arranged on the top of the heat sink 313, so the heat conducting plate 502 can also be used to absorb part of the heat during use, further improving The heat dissipation performance of the semiconductor cooling sheet 311 is improved. When the heat dissipation performance of the semiconductor cooling sheet 311 is to be further improved according to the demand, the rotation speed of the fan shaft 306 can be reduced first. At this time, the spring seat 507 will push the piston rod 504 to make the roller 505 fit with the cam 506. Therefore, when the concave part of the cam 506 is aligned with the roller 505, the spring seat 507 will drive the piston rod 504 to move, and the water in the water tank 501 can be sucked into the fixed cylinder 503 through the first one-way valve 508. After that, when the convex part of the cam 506 squeezes the roller 505, the piston rod 504 can draw the water inside the fixed cylinder 503 from the second one-way valve 509. The water mist is squeezed into the spray tube 510, and the water mist is sprayed out and attached to the hot end of the heat sink 313 and the semiconductor refrigeration plate 311. After repeated many times, the fan shaft 306 is controlled to rotate at a high speed, and the evaporation heat absorption performance of water can be used to further improve the heat dissipation and cooling effect of the semiconductor refrigeration plate 311, and it can also avoid the situation where excessive waste caused by continuous spraying. In addition, when encountering a rainy environment, rainwater can pass through the barrier net 608 and enter the collecting plate 604, and the V-shaped collecting plate 604 will guide the rainwater to concentrate it in the middle. When a certain amount of rainwater accumulates on the collecting plate 604, it will cause the weight of the collecting plate 604 to be greater than the pressure. The supporting force of the compression spring 603 is reduced, and the collecting plate 604 will slide down, so that the sealing plug 606 is separated from the liquid inlet 605, so that the rainwater on the top of the collecting plate 604 flows to the filter plate 601 through the liquid inlet 605, and after being filtered by the filter plate 601, it flows to the lower part of the water tank 501 for collection, so as to collect and utilize the rainwater, and when the top of the collecting plate 604 becomes lighter, the compression spring 603 will push the collecting plate 604 under the limit of the sliding rod 602 and the filter plate 601, so that the sealing plug 606 blocks the liquid inlet 605, thereby automatically sealing the water tank 501 to prevent excessive loss of water inside the water tank 501 due to natural evaporation.

[0025] In summary, when using this safe power distribution cabinet that can dissipate heat and cool down autonomously, first, after closing the cabinet door 1, since the entire interior of the equipment is in a sealed state, external water vapor and dust cannot enter the interior of the cabinet 1. Secondly, the dual-axis motor 303 will drive the driven gear 305 to rotate through the active gear 304, so that the two fans on the fan shaft 306 rotate at the same time. Therefore, during use, the lower fan blades can send the airflow inside the heat exchange box 310 into the shunt pipe 307, and blow it to the electrical components from the blowing pipe 308. In this process, the dual-axis motor 303 will also drive the rotating plate 402 to rotate through the reducer 401. At this time, since the cabinet 1 will limit the moving direction of the synchronization rod 405, the rotating plate 40 2 will push and pull the limit plate 404 back and forth through the sliding column 403, so that the synchronization rod 405 drives the driving column 406 to move up and down reciprocatingly, thereby driving the blowing pipe 308 to rotate back and forth through the driving plate 407, so as to automatically adjust the angle of the blowing pipe 308 when the air is discharged. Then, the airflow after heat exchange can flow into the heat exchange box 310 through the return pipe 309. At this time, the heat exchange plate 312 is used to cool the airflow while guiding the airflow to extend the stroke inside the heat exchange box 310, so that the airflow inside the cabinet 1 can be circulated to dissipate heat and cool down. In this process, the fan blades on the top of the fan shaft 306 will also drive the airflow on the upper part of the fixed box 301 to flow, and the external air will enter under the filtration of the dustproof mesh plate 314. To the upper end of the heat exchange box 310, the heat sink 313 is used to improve the heat dissipation and cooling effect of the hot end of the semiconductor refrigeration plate 311, and then the air flow is discharged from the upper end of the fixed box 301, so as to automatically dissipate the heat of the semiconductor refrigeration plate 311. Then, since the fan shaft 306 rotates at a fast speed, the damper in the spring seat 507 will delay the reset time of the spring, so that when the fan shaft 306 rotates at a high speed, the roller 505 will not be able to move to the recessed part of the cam 506 due to the delay. Only when the speed is reduced can the roller 505 move to the recessed part of the cam 506. Therefore, it is only necessary to control the speed of the dual-axis motor 303 to switch the working state of the heat absorption component 5, and when it is necessary to further improve the semiconductor manufacturing speed according to the needs. When the heat dissipation performance of the cooling sheet 311 is improved, the rotation speed of the fan shaft 306 is first reduced. At this time, the spring seat 507 will push the piston rod 504 to make the roller 505 fit with the cam 506. Therefore, when the concave part of the cam 506 is aligned with the roller 505, the spring seat 507 will drive the piston rod 504 to move, and the water in the water tank 501 can be sucked into the fixed cylinder 503 through the first one-way valve 508. After that, when the convex part of the cam 506 squeezes the roller 505, the piston rod 504 can squeeze the water inside the fixed cylinder 503 from the second one-way valve 509 to the spray pipe 510, and the water mist is sprayed out and attached to the heat sink 313 and the hot end of the semiconductor cooling sheet 311. After repeating many times, the fan shaft 306 is controlled to rotate at a high speed.The heat absorption performance of water evaporation can be used to further improve the heat dissipation and cooling effect of the semiconductor refrigeration plate 311. Finally, in rainy days, rainwater can enter the collecting plate 604 through the barrier net 608. When a certain amount of rainwater accumulates on the collecting plate 604, the weight of the collecting plate 604 will be greater than the supporting force of the compression spring 603. At this time, the collecting plate 604 will slide down, so that the sealing plug 606 is separated from the liquid inlet 605, so that the rainwater on the top of the collecting plate 604 Water flows to the filter plate 601 through the liquid inlet 605, and after being filtered by the filter plate 601, it flows to the lower part of the water tank 501 for collection, so as to collect and utilize rainwater. When the top of the collector plate 604 becomes lighter, the compression spring 603 will push the collector plate 604 under the limit of the slide bar 602 and the filter plate 601, so that the sealing plug 606 blocks the liquid inlet 605, thereby automatically sealing the water tank 501 to prevent the water inside the water tank 501 from being lost too much due to natural evaporation.
