Description

Technical Field

[0001] The present invention belongs to the technical field of distribution cabinets, and particularly relates to a power terminal voltage regulation distribution cabinet. Background Art

[0002] A distribution cabinet is a general term for a motor control center. The distribution cabinet assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements, and is an important component for power distribution.

[0003] Since a large number of power equipment in the distribution cabinet are placed together and used at the same time, a large amount of heat will be generated, resulting in a continuous increase in the ambient temperature. Therefore, it is necessary to dissipate heat from it; the overall heat dissipation effect of the existing distribution cabinet is not good, and most of them use a single simultaneous heat dissipation fan or blower to blow for heat dissipation. The heat dissipation method is single and the effect is not good. In addition, the overall anti-collision effect of the existing distribution cabinet is not good. When the cabinet body is hit, the internal electrical components are easily damaged and need to be improved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a power terminal voltage regulation distribution cabinet, which solves the problems of uneven heat dissipation and poor anti-collision effect in the prior art.

[0005] A power terminal voltage regulation distribution cabinet includes a distribution cabinet main body and a support column, and the distribution cabinet main body is arranged on the support column; its characteristics are: a cooling cavity is arranged at the lower part of the distribution cabinet main body, and a temperature reduction component and a blocking component are arranged inside the cooling cavity; a blower is arranged on the lower side outside the cooling cavity, and the air outlet of the blower is communicated with the inside of the cooling cavity; the top of the cooling cavity is communicated with the inside of the distribution cabinet main body through a heat dissipation air outlet; buffer components are arranged on both side walls of the distribution cabinet main body; and a circulating heat dissipation hose is arranged between the buffer component and the side wall of the distribution cabinet main body.

[0006] The temperature reduction component includes a rectangular cooling water tank, a refrigeration sheet is arranged inside the rectangular cooling water tank, a partition plate is arranged in the central part of the rectangular cooling water tank, and a ventilation opening is arranged on the partition plate.

[0007] A U-shaped air duct is arranged inside the rectangular cooling water tank; both ends of the U-shaped air duct extend to the central part of the rectangular cooling water tank; the air inlet of the U-shaped air duct is located on one side below the partition plate; the air outlet of the U-shaped air duct is located on one side above the partition plate, and a one-way valve is arranged in the air outlet of the U-shaped air duct.

[0008] The blocking component includes a sealed cavity column which is fixedly installed at the inner top of the cooling cavity. A piston plate is arranged inside the sealed cavity column; a temperature-sensitive liquid is filled in the space formed between the piston plate and the inner part of the sealed cavity column; a heat-conducting sheet is arranged at the top of the sealed cavity column. One end of the heat-conducting sheet is communicated with the inside of the main body of the power distribution cabinet, and the other end of the heat-conducting sheet is in contact with the temperature-sensitive liquid; a piston rod is fixedly connected to the bottom end of the piston plate; one end of the piston rod extends outside the sealed cavity column and is fixedly connected with a baffle plate matching the ventilation opening.

[0009] The buffering component includes a collision-proof plate and a buffering spring. The collision-proof plate is fixedly connected to the side wall of the main body of the power distribution cabinet through the buffering spring.

[0010] The circulating heat dissipation hose is distributed in a serpentine shape on the side wall of the main body of the power distribution cabinet. Both ends of the circulating heat dissipation hose are communicated with the inside of the rectangular cooling water tank, and a circulating pump is arranged on the circulating heat dissipation hose.

[0011] Through the above design scheme, the present invention can bring the following beneficial effects: For a power distribution cabinet for regulating the voltage of an electric power terminal, by arranging a temperature-lowering component, during the working process, air flow generated by the fan operation can be sent into the cooling cavity, and then enter the cabinet body through the ventilation opening and the heat dissipation opening, promoting the air flow inside the cabinet body and increasing the heat dissipation effect. When the temperature inside the cabinet body continuously increases, the temperature-sensitive liquid can be heated and expanded to push the piston plate downward, so that the baffle plate blocks the ventilation opening, and then the air flow generated by the fan enters the U-shaped air duct. The cooling water in the rectangular cooling water tank is used to cool the air flow in the U-shaped air duct, and the cooled air flow enters the main body of the power distribution cabinet.

[0012] By arranging a buffering component and providing a circulating heat dissipation hose between the buffering component and the main body of the power distribution cabinet, the collision force received by the main body of the power distribution cabinet can be buffered and shock-absorbed by the collision-proof plate and the buffering spring. At the same time, on the one hand, the circulating heat dissipation hose can use the cooling water to cool and dissipate heat from the main body of the power distribution cabinet, and at the same time, the circulating heat dissipation hose can buffer the impact received by the collision-proof plate, increasing the anti-collision effect of the main body of the power distribution cabinet.

Specific implementation mode

[0018] A power terminal voltage regulation power distribution cabinet, as Figures 1 - 3 shown, includes a power distribution cabinet main body 1. Support columns 3 are provided at the bottom end of the power distribution cabinet main body 1. A cooling cavity 11 is provided at the bottom end inside the power distribution cabinet main body 1. A temperature - lowering component is provided inside the cooling cavity 11. A fan 2 is provided at the bottom end of the power distribution cabinet main body 1. The air outlet of the fan 2 is communicated with the inside of the cooling cavity 11. The top end of the cooling cavity 11 is communicated with the inside of the power distribution cabinet main body 1 through a heat dissipation air outlet 12. Buffer components are provided on both side walls of the power distribution cabinet main body 1. A circulating heat dissipation hose 7 is provided between the buffer components and the side wall of the power distribution cabinet main body 1.

[0019] Among them, the temperature - lowering component includes a square - shaped cooling water tank 4 provided inside the cooling cavity 11. A refrigeration sheet 6 is provided inside the square - shaped cooling water tank 4. A partition plate 13 is provided in the central part of the square - shaped cooling water tank 4. A ventilation opening 14 is opened on the partition plate 13. A blocking component is provided directly above the ventilation opening 14. The refrigeration sheet 6 can be used to cool the cooling water inside the square - shaped cooling water tank 4. By providing ventilation holes, it is convenient for the air flow generated by the fan 2 to directly enter the cabinet interior through the ventilation holes. When the temperature inside the cabinet is relatively high, the blocking component can be used to block the ventilation opening 14, and at the same time, the air flow generated by the fan 2 enters the U - shaped air duct 5, is cooled and then sent into the cabinet interior, increasing the heat dissipation effect.

[0020] Among them, the blocking component includes a sealed cavity column 17, which is fixedly installed at the inner top end of the cooling cavity 11. A piston plate 19 is arranged inside the sealed cavity column 17. A temperature-sensitive liquid 20 is filled in the space formed inside the piston plate 19 and the sealed cavity column 17. A heat conduction plate 21 is arranged at the top end of the sealed cavity column 17. One end of the heat conduction plate 21 is communicated with the inside of the power distribution cabinet main body 1, and the other end of the heat conduction plate 21 is in contact with the temperature-sensitive liquid 20. A piston rod 18 is fixedly connected to the bottom end of the piston plate 19. One end of the piston rod 18 extends outside the sealed cavity column 17 and is fixedly connected with a baffle 15 matching the ventilation opening 14. When the temperature inside the cabinet body continuously rises, the heat conduction plate 21 conducts the temperature inside the cabinet body to the temperature-sensitive liquid 20. The temperature-sensitive liquid 20 is heated and collides to push the piston plate 19 and the piston rod 18 to move, so that the baffle 15 moves downward to block the ventilation opening 14, so that the air flow generated by the fan 2 can enter the U-shaped air duct 5 for cooling.

[0021] Among them, the buffer component includes a collision prevention plate 9 and buffer springs 10. The collision prevention plate 9 is fixedly connected to the side wall of the power distribution cabinet main body 1 through a plurality of buffer springs 10. By arranging the collision prevention plate 9 and the buffer springs 10, when the side of the cabinet body is collided, the impact received by the cabinet body can be buffered by the collision prevention plate 9 and the buffer springs 10. At the same time, the collision prevention plate 9 can protect the circulating heat dissipation hose 7 from being exposed to the sun.

[0022] Among them, the circulating heat dissipation hose 7 is distributed in a snake shape on the side wall of the power distribution cabinet main body 1. Both ends of the circulating heat dissipation hose 7 are communicated with the inside of the rectangular cooling water tank 4. A circulating pump 8 is arranged on the circulating heat dissipation hose 7. The circulating pump 8 can be used to extract the cooling water inside the rectangular cooling water tank 4 and enter the inside of the circulating heat dissipation hose 7 to adsorb the heat on the side wall of the cabinet body, increasing the heat dissipation effect of the power distribution cabinet main body 1.

[0023] The working principle of the present invention is as follows. When the power distribution cabinet main body 1 generates heat during operation, the fan 2 can be operated to generate an air flow, which enters the interior of the cabinet through the ventilation opening 14 and the heat dissipation air outlet 12, promoting the air flow inside the cabinet. The flowing air is discharged through the air outlet on the cabinet, and while dissipating heat, the circulation pump 8 is started to retrieve the cooling water inside the figure-eight cooling water tank 4 and enter it into the circulation heat dissipation hose 7 to adsorb the heat on the side wall of the cabinet, enhancing the heat dissipation effect of the power distribution cabinet main body 1. When the temperature inside the cabinet continues to rise, the heat conducting sheet 21 conducts the temperature inside the cabinet to the temperature-sensitive liquid 20. The temperature-sensitive liquid 20 is heated and collides, pushing the piston plate 19 and the piston rod 18 to move, causing the baffle 15 to move downward to block the ventilation opening 14. As a result, the air flow generated by the fan 2 can enter the U-shaped air duct 5, and the air flow entering the U-shaped air duct 5 can be cooled by the cooling water in the figure-eight cooling water tank 4 and then discharged into the interior of the cabinet, increasing the heat dissipation effect. At the same time, the setting of the one-way valve 16 can prevent the air flow from flowing back. By providing a buffer assembly on the side wall of the cabinet, when the side of the cabinet is collided, the impact received by the cabinet can be buffered by the anti-collision plate 9 and the buffer spring 10. At the same time, the circulation heat dissipation hose 7 can buffer the impact received by the anti-collision plate 9, enhancing the anti-collision effect of the power distribution cabinet main body 1. Moreover, the anti-collision plate 9 can protect the circulation heat dissipation hose 7 from being exposed to the sun, ensuring good heat dissipation effect and convenient use.
