Description

Technical Field

[0001] This utility model belongs to the technical field of cooling devices, specifically relating to a cooling device for a power cabinet used in power applications. Background Technology

[0002] In power systems, power cabinets serve as crucial carriers of electrical equipment. Their internal components generate significant heat during operation. If this heat cannot be dissipated promptly, it will severely impact the normal operation and lifespan of the power cabinet. Currently, common power cabinet cooling devices on the market typically employ cooling fans in conjunction with filter components for heat dissipation. The filter components filter the air entering the power cabinet to prevent dust and other impurities from entering and affecting component operation. For example, a power cabinet cooling device is disclosed in Chinese Patent Publication No. CN217362215U.

[0003] In actual long-term use, the filter components will gradually accumulate a lot of dust due to the continuous interception of airborne particles, which will increase the airflow resistance and reduce the ventilation efficiency of the cooling fan, resulting in a significant decline in the heat dissipation performance of the entire cooling system.

[0004] However, since maintenance personnel often have difficulty accurately assessing the dust accumulation on the filter components, they frequently need to conduct manual inspections. This not only increases maintenance costs but may also lead to the failure of the device's heat dissipation and filtration functions due to untimely inspections. Summary of the Invention

[0005] The purpose of this utility model is to provide a cooling device for power cabinets, which solves the problem of dust accumulation in the filter components of the cooling device. This is because regular manual inspection is required, which leads to increased maintenance costs and may cause the device's heat dissipation and filtration functions to fail due to untimely cleaning.

[0006] The specific technical solution adopted by this utility model is as follows: A power cabinet cooling device includes a first square tube, a cooling fan fixedly connected to the inner wall of the first square tube, a rectangular hole on the left side of the first square tube, a first rectangular tube fixedly connected to the inner wall of the rectangular hole, a second rectangular tube fitted onto the surface of the first rectangular tube, a sliding groove on the right side of the first rectangular tube, a sealing plate fitted to the inner wall of the first rectangular tube, sliding columns fixedly connected to the upper and lower sides of the sealing plate and the inner wall of the second rectangular tube, the surface of the sliding columns fitting against the inner wall of the sliding groove, a pressing block fixedly connected to the upper surface of the second rectangular tube, a spring fixedly connected to the right side of the pressing block, a pressing switch fitted to the left side of the pressing block, the left side of the pressing switch fixedly connected to the inner wall of the first square tube, an indicator light fixedly connected to the front of the first square tube, a filter assembly fitted to the inner wall of the first square tube, a U-shaped column fixedly connected to the bottom of the filter assembly, a fixing bolt fitted to the inner wall of the U-shaped column, and nuts fixedly connected to the left and right sides of the first square tube, the inner wall of the nuts threadedly connected to the surface of the fixing bolts.

[0007] The present invention is further configured such that the filter assembly comprises a second square cylinder, a first filter screen, a second filter screen, an activated carbon plate, and a horizontal plate. The surface of the second square cylinder is attached to the inner wall of the first square cylinder. The surfaces of the first filter screen and the second filter screen are both fixedly connected to the inner wall of the second square cylinder. The activated carbon plate is located between the first filter screen and the second filter screen. The upper surface of the second square cylinder and the upper surface of the U-shaped column are both fixedly connected to the bottom of the horizontal plate.

[0008] The present invention is further configured such that both the first filter screen and the second filter screen are perforated stainless steel mesh, the first filter screen is located above the activated carbon plate, the second filter screen is located below the activated carbon plate, the pore size of the first filter screen is 5mm, and the pore size of the second filter screen is 2mm.

[0009] The present invention is further configured such that the push switch, the indicator light and the power supply form a series circuit, and the push switch is a normally closed switch.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figures 1 to 10 As shown, a power cabinet cooling device includes a first square tube 1, a cooling fan 2 fixedly connected to the inner wall of the first square tube 1, a rectangular hole 3 on the left side of the first square tube 1, a first rectangular tube 4 fixedly connected to the inner wall of the rectangular hole 3, a second rectangular tube 5 fitted onto the surface of the first rectangular tube 4, a sliding groove 6 on the right side of the first rectangular tube 4, a sealing plate 7 fitted against the inner wall of the first rectangular tube 4, sliding columns 8 fixedly connected to the upper and lower sides of the sealing plate 7 and the inner wall of the second rectangular tube 5, the surface of the sliding columns 8 fitting against the inner wall of the sliding groove 6, and a pressing block 9 fixedly connected to the upper surface of the second rectangular tube 5. A spring 10 is fixedly connected to the right side of the pressing block 9. A press switch 11 is attached to the left side of the pressing block 9. The left side of the press switch 11 is fixedly connected to the inner wall of the first square tube 1. An indicator light 12 is fixedly connected to the front of the first square tube 1. A filter assembly 13 is attached to the inner wall of the first square tube 1. A U-shaped column 14 is fixedly connected to the bottom of the filter assembly 13. A fixing bolt 15 is attached to the inner wall of the U-shaped column 14. Nuts 16 are fixedly connected to both the left and right sides of the first square tube 1. The inner wall of the nut 16 is threadedly connected to the surface of the fixing bolt 15. Mounting brackets 23 are fixedly connected to both the left and right sides of the first square tube 1.

[0019] The filter assembly 13 includes a second square tube 131, a first filter screen 132, a second filter screen 133, an activated carbon plate 134, and a horizontal plate 135. The surface of the second square tube 131 is attached to the inner wall of the first square tube 1. The surfaces of the first filter screen 132 and the second filter screen 133 are both fixedly connected to the inner wall of the second square tube 131. The activated carbon plate 134 is located between the first filter screen 132 and the second filter screen 133. The upper surface of the second square tube 131 and the upper surface of the U-shaped column 14 are both fixedly connected to the bottom of the horizontal plate 135.

[0020] Both the first filter screen 132 and the second filter screen 133 are perforated stainless steel mesh. The first filter screen 132 is located above the activated carbon plate 134, and the second filter screen 133 is located below the activated carbon plate 134. The pore size of the first filter screen 132 is 5mm, and the pore size of the second filter screen 133 is 2mm.

[0021] The push switch 11, indicator light 12 and power supply form a series circuit, and the push switch 11 is a normally closed switch.

[0022] It should be noted that the second rectangular tube 5 is connected to the sealing plate 7 by the sliding column 8, and the sliding column 8 can slide in the sliding groove 6. When the sealing plate 7 is located in the first rectangular tube 4, the first rectangular tube 4 is sealed by the sealing plate 7.

[0023] When the dust adsorbed on the filter assembly 13 is small, the air outside the first square cylinder 1 enters the first square cylinder 1 smoothly through the filter assembly 13. At this time, since the air pressure difference inside and outside the first square cylinder 1 is less than the elastic force of the spring 10, the elastic force of the spring 10 causes the pressing block 9 to press the pressing switch 11, and the pressing switch 11 turns off the indicator light 12. When dust is adsorbed on the filter assembly 13, the air pressure difference inside and outside the first square cylinder 1 will increase as the dust on the filter assembly 13 increases. As the air pressure difference increases, the sealing plate 7 moves to the right. When the amount of dust on the filter assembly 13 reaches the threshold, the air pressure difference inside and outside the first square cylinder 1 causes the pressing block 9 to separate from the pressing switch 11. At this time, the pressing switch 11 turns on the indicator light 12, and then the lit indicator light 12 transmits a cleaning warning signal to the maintenance personnel, ensuring that the maintenance personnel can perform cleaning and maintenance operations on the filter assembly 13 in a timely manner.

[0024] Dust in the air can be filtered through the first filter screen 132 and the second filter screen 133, and water vapor in the air can be filtered through the activated carbon plate 134. The filter assembly 13 and the first square tube 1 are easy to assemble and disassemble through the cooperation of the U-shaped plate, the horizontal plate 135, the fixing bolts 15 and the nuts 16.

[0025] like Figures 1 to 7As shown, a circular hole 17 is provided on the right side of the first square tube 1. A threaded cylinder 18 is fixedly connected to the inner wall of the circular hole 17. An adjusting bolt 19 is connected to the inner wall of the threaded cylinder 18. A bearing 20 is fixedly connected to the surface of the adjusting bolt 19. A connecting plate 21 is fixedly connected to the outer ring of the bearing 20. A cylinder 22 is fixedly connected to the left side of the connecting plate 21. The inner wall of the cylinder 22 and the left side of the connecting plate 21 are both in contact with the surface of the spring 10.

[0026] It should be noted that when the adjusting bolt 19 is rotated, the connecting plate 21 can be moved to the right or left by the cooperation of the adjusting bolt 19 and the threaded cylinder 18. At this time, by adjusting the position of the connecting plate 21, the pushing force of the spring 10 on the pressing block 9 when the pressing block 9 is separated from the pressing switch 11 can be changed. This allows maintenance personnel to adjust the amount of dust adsorbed on the filter assembly 13 when the indicator light 12 is lit according to different working conditions, so as to plan the cleaning and maintenance cycle more scientifically.

[0027] The working principle of this utility model is as follows: First, the cooling device is fixed at the heat dissipation hole of the power cabinet by the mounting bracket 23. Then, the cooling fan is turned on, and the air outside the first square cylinder 1 is made to enter the first square cylinder 1 through the first filter screen 132, the activated carbon plate 134 and the second filter screen 133 in sequence. At this time, the air entering the first square cylinder 1 is treated by dust removal and dehumidification through the cooperation of the first filter screen 132, the activated carbon plate 134 and the second filter screen 133. The treated air enters the power cabinet through the cooling fan 2 and accelerates the air circulation in the power cabinet, thereby achieving the effect of cooling the inside of the power cabinet.

[0028] During use, the air pressure difference between the inside and outside of the first square cylinder 1 increases as dust accumulates on the filter assembly 13. As the air pressure difference increases, the sealing plate 7 moves to the right. When the amount of dust on the filter assembly 13 reaches a threshold, the pressure difference between the inside and outside of the first square cylinder 1 causes the pressing block 9 to separate from the pressing switch 11. At this time, the pressing switch 11 turns on the indicator light 12, and then the lit indicator light 12 transmits a cleaning warning signal to the maintenance personnel, ensuring that the maintenance personnel can perform cleaning and maintenance operations on the filter assembly 13 in a timely manner.

[0029] When the filter assembly 13 needs to be cleaned, it can be removed from the first square tube 1 by unscrewing the fixing bolt 15 from the nut 16. After the filter assembly 13 is cleaned, it is inserted back into the first square tube 1. Then, the fixing bolt 15 is inserted into the U-shaped column 14 and screwed into the nut 16. At this time, the filter assembly 13 can be fixed in the first square tube 1 by the cooperation of the fixing bolt 15, the nut 16, the U-shaped column 14 and the horizontal plate 135.

[0030] When maintenance personnel need to adjust the amount of dust adsorbed on the filter assembly 13 when the indicator light 12 is on for different working conditions, they can change the pushing force of the spring 10 on the press block 9 when the press block 9 is separated from the press switch 11 by rotating the adjusting bolt 19. At this time, the amount of dust adsorbed on the filter assembly 13 when the indicator light 12 is on can be adjusted.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
