Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage frequency converters, and more specifically, to a high-voltage frequency converter power cabinet. Background Art

[0002] High-voltage inverter power cabinet is one of the key components in the high-voltage inverter system. It is mainly used to realize the conversion and distribution of power and provide adjustable power for high-voltage motors or other loads. It is usually used in industrial fields, such as large equipment in mining, cement, petrochemical, power and other industries, with the purpose of saving energy, improving efficiency and improving the operating stability of the system.

[0003] When the capacity of the high-voltage inverter power cabinet is large or it is running under high load and high temperature environment, air cooling may not meet the heat dissipation requirements, so a water cooling system is required. The water cooling principle of the high-voltage inverter power cabinet is to remove the heat generated during the operation of the system through circulating water, keep the equipment within a safe temperature range, and thus ensure its stable operation.

[0004] After the circulating water absorbs the heat generated during the operation of the equipment, it flows through the heat sink fins to exchange heat with it. The heat sink fins then drive the air flow through the fan to efficiently dissipate the heat to the external environment, thereby realizing the cooling and heat dissipation functions of the equipment. Air always passes through the heat sink fins for heat exchange, but as the heat dissipation system works for a long time, a large amount of dust and impurities will adhere to the surface of the heat sink fins, resulting in a significant reduction in heat dissipation efficiency. If not cleaned in time, it may cause the equipment to overheat or even malfunction. Therefore, the heat sink fins need to be maintained and cleaned regularly. However, the heat dissipation system integrated in the high-voltage inverter power cabinet has a small space and complex structure, and the manual cleaning process is very troublesome.

The lifting plate 43 is slidably connected in the ventilation chamber 21, and two sliding grooves 44 are symmetrically arranged inside the lifting plate 43. One ends of the two lifting rods 45 are respectively slidably connected in the corresponding sliding grooves 44, and the other ends of the two lifting rods 45 are respectively slidably connected in the corresponding side boxes 13, and a support rod 46 is fixed on each lifting rod 45, and the support rod 46 is slidably connected in the corresponding guide groove 35.

[0036] The cleaning mechanism 5 also includes an adjustment groove 52 arranged on the surface of the push plate 51, and a slider 54 is fixed on the other side of the translation plate 53.

A number of convex teeth 57 are equidistantly fixed on the side of the translation plate 53.

The lifting wedge block 58 is elastically connected to the inside of the side box 13 through the second spring 591, and the lifting wedge block 58 contacts the bottom surface of the push plate 51, and a paddle plate 59 is arranged at the end of the lifting wedge block 58.

[0037] A limiting mechanism 6 is installed in the side box 13 at the end of the push plate 51, and the limiting mechanism 6 includes a lever 61 installed inside the side box 13, and two second shafts 62 are symmetrically installed on both sides of the middle part of the lever 61. The lever 61 is rotatably connected to the inside of the side box 13 through the second shaft 62, and a second torsion spring 63 is sleeved on the second shaft 62. The second shaft 62 is elastically connected to the inside of the side box 13 through the second torsion spring 63, and both ends of the lever 61 are rotatably connected to an extrusion block 64. The side of the extrusion block 64 at the top of the lever 61 is rotatably connected to one end of a lever 65, and the middle part of the lever 65 is rotatably connected to the inside of the side box 13, and the other end of the lever 65 is installed with a blocking plate 66.

[0038] A cooling system 33 is installed inside the heat sink 12 on the top of the power cabinet 11, as shown in the attached manual. Figure 2 As shown, a three-way valve 31 is installed inside the power cabinet 11 (the three-way valve 31 is an electric three-way valve and can be electrically controlled by a worker), and the water pipe 32 at the bottom of the three-way valve 31 is a circulating water pipe (not fully drawn in the drawings of the specification), which is used to absorb the heat generated by the electrical equipment inside the power cabinet 11, thereby reducing the temperature of the equipment and ensuring the smooth operation of the equipment; the water pipe 32 in the middle of the three-way valve 31 is connected to the water injection cylinder 41; the water pipe 32 at the top of the three-way valve 31 is connected to the cooling system 33. Under normal conditions, when the electrical equipment inside the power cabinet 11 is cooled, the three-way valve 31 connects the water pipes 32 at the upper and lower ends thereof, and the water that absorbs heat enters the cooling system 33 for cooling, and then circulates to the power cabinet 11 to continue absorbing heat. The heat transferred to the cooling system 33 is finally conducted to the fins 34, and the motor 25 in the ventilation chamber 21 rotates, driving the fan blades 26 to rotate, thereby generating an air flow that enters from one end of the heat sink 12 and is discharged from the other end, and flows inside the ventilation chamber 21. The flowing air flow passes through a number of fins 34 arranged in parallel, and takes away the heat on the fins 34, thereby achieving a circulating cooling effect.

[0039] Due to the long-term exchange of airflow inside and outside the ventilation chamber 21, external dust and other impurities are easily attached to the fins 34, which in turn reduces the thermal conductivity of the fins 34. Therefore, after the cooling water in the heat dissipation mechanism 3 circulates for a certain period, the three-way valve 31 automatically adjusts (the automatic adjustment interval of the three-way valve 31 can be freely controlled by the worker), so that the cooling water in the water pipe 32 below the three-way valve 31 enters the water pipe 32 in the middle of the three-way valve 31, and finally flows into the water injection cylinder 41. The cooling water enters from the bottom of the water injection cylinder 41. The entry of water causes the piston 42 to rise, and the piston 42 drives the lifting plate 43 to rise. The lifting plate 43 drives the lifting rods 45 on both sides thereof to rise synchronously. The end of the lifting rod 45 slides in the side box 13, and in the initial state, the end of the lifting rod 45 is at the bottom of the dial plate 59. When the lifting rod 45 rises, the end of the lifting rod 45 contacts and lifts the dial plate 59, so that the dial plate 59 drives the lifting wedge 58 to rise, and the lifting wedge 58 stretches the second elastic The spring 591 simultaneously pushes against the bottom surface of the push plate 51 to make the push plate 51 slide horizontally in the direction close to the cooling system 33 (the top surface of the lifting wedge 58 and the bottom surface of the push plate 51 are mutually matched inclined surfaces, and the lifting wedge 58 can be squeezed to make the push plate 51 slide horizontally in the direction close to the cooling system 33 during the rising process), and the push plate 51 drives the translation plate 53 to move, and the brush heads 56 on the side of the translation plate 53 slide from the side box 13 into the ventilation chamber 21 inside the heat sink 12, and the distribution of the brush heads 56 can just be inserted between every two adjacent fins 34. When the lifting rod 45 lifts the lifting wedge 58 to make the brush head 56 slide the maximum distance, the upper and lower surfaces and the front end of the corresponding brush head 56 just touch the side surfaces of the two adjacent fins 34 and the side surfaces of the cooling system 33. In the process of the brush head 56 being inserted between the two adjacent fins 34, the fins 34 are brushed, thereby achieving a cleaning effect.

[0040] A plurality of dustproof plates 27 are installed on the inner walls of the heat dissipation box 12 on both sides of the ventilation chamber 21. In the heat dissipation state, the first torsion springs 29 on the first shafts 28 at both ends of the dustproof plates 27 have elastic force, so that the dustproof plates 27 are not easy to shake, thereby closing the side box 13 to prevent dust and other impurities from entering the side box 13 and dirtying the brush head 56. When the brush head 56 slides from the side box 13 into the ventilation chamber 21, the end of the brush head 56 contacts and pushes the dustproof plate 27, so that the dustproof plate 27 is driven and rotated around the first shaft 28, so that the first torsion spring 29 accumulates force. The rotation of the dustproof plate 27 connects the side box 13 with the ventilation chamber 21, and the brush head 56 is able to enter the ventilation chamber 21.

[0041] The cleaning effect of the above cleaning method is limited, and it is difficult to completely remove the impurities adsorbed on the surface of the fin 34. Therefore, two guide grooves 35 are symmetrically arranged at the end of the cooling system 33, and the guide groove 35 is composed of a lower groove close to the two sides of the cooling system 33 and an upper groove away from the two sides of the cooling system 33 (see the attached manual). Figure 3As shown in the figure, and there is a smooth transition between the first groove and the second groove. During the process of the lifting plate 43 driving the lifting rod 45 to rise, the support rod 46 on the lifting rod 45 slides in the corresponding guide groove 35, and in the process of pushing out the brush head 56 by the lifting wedge 58, the support rod 46 always slides in the first groove (as mentioned above, during this process, the end of the lifting rod 45 is always at the bottom of the dial plate 59). When the brush head 56 slides out the maximum distance, the support rod 46 slides to the top of the first groove and transitions to the second groove. During the transition process, the support rod 46 has a horizontal sliding distance away from the dial plate 59. This sliding distance makes the lifting rod 45 slide toward the inside of the lifting plate 43, and makes the end of the lifting rod 45 slide out from the bottom of the dial plate 59, and can no longer push the dial plate 59 to continue to rise. Then the lifting plate 43 continues to drive the lifting rod 45 to rise, the support rod 46 slides in the second-stage groove, and the lifting rod 45 successively contacts several convex teeth 57 on the side of the translation plate 53, so that the translation plate 53 drives the brush head 56 and the slider 54 to slide in the direction away from the lifting rod 45, and the slider 54 slides in the adjustment groove 52 to compress the first spring 55. When the lifting rod 45 no longer contacts the convex teeth 57, the first spring 55 uses its elastic force to push the slider 54 to return, and the slider 54 drives the translation plate 53 to return, that is, drives the brush head 56 to return, so that the brush head 56 slides back and forth horizontally between the fins 34, thereby repeatedly wiping the surface of the fin 34 and the side of the cooling system 33, thereby improving the cleaning effect, and then effectively removing impurities attached to the surface of the fin 34. After the cooling water in the water injection cylinder 41 is discharged, the piston 42 uses gravity to drive the lifting plate 43 to descend, and the lifting rod 45 can once again contact the plurality of convex teeth 57, further driving the translation plate 53 to slide back and forth, so that the brush head 56 wipes the fins 34 again, further increasing the cleaning force and improving the cleaning effect as much as possible.

[0042] After the lifting rod 45 slides out from the bottom of the dial plate 59, the lifting wedge 58 may fall down under the elastic force of the second spring 591 because it has no support, so it cannot continuously resist the push plate 51, so that the brush head 56 is always between the fins 34. Therefore, a cleaning mechanism 7 is provided inside each side box 13. No cooling water is injected into the water injection cylinder 41, so that the lifting rod 45 is at the lowest point, and the lifting rod 45 squeezes the squeezing block 64 at the bottom end of the lever 61, so that the lever 61 remains tilted, and the squeezing block 64 at the top of the lever 61 protrudes. When the brush head 56 is about to slide to the maximum distance, the lifting rod 45 contacts the squeezing block 64 at the top of the lever 61, so that the squeezing block 64 is retracted, thereby driving the lever 61 to rotate. The lever 61 drives the second shaft 62 to rotate inside the side box 13 and compresses the second torsion spring 63. The swing of the lever 61 causes the squeezing block 64 at the bottom to slide out again. In this way, when the lifting rod 45 is reset, it can contact the squeezing block 64 at the bottom again, so that the squeezing block 64 at the top of the lever 61 protrudes again. The extrusion block 64 at the top of the lever 61 slides, and the blocking plate 66 is rotated to the bottom of the dial plate 59 through the dial rod 65 (when the lifting rod 45 contacts the extrusion block 64 at the top of the lever 61, the height of the dial plate 59 has exceeded the height of the blocking plate 66), thereby lifting the dial plate 59 and supporting the lifting wedge block 58 to prevent the lifting wedge block 58 from falling, thereby ensuring that the brush head 56 is always between the fins 34.

[0043] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 12 The cleaning mechanism 7 is installed inside the heat dissipation box 12. The cleaning mechanism 7 includes a connecting rod 71 whose bottom end is rotatably connected to the top of the lifting plate 43. The heat dissipation box 12 is rotatably connected to a rotating wheel 72, and the top of the connecting rod 71 is rotatably connected to the side edge of the rotating wheel 72. The heat dissipation box 12 is rotatably connected to a long rod 73. One end of the long rod 73 is installed at the center of the rotating wheel 72, and the other end of the long rod 73 is installed with a gear 74. A shell 75 is installed outside one end of the heat dissipation box 12, and the gear 74 is rotatably connected to the inside of the shell 75. The inside of the shell 75 A gear ring 76 is also rotatably connected, and the gear ring 76 is meshed with the gear 74. A connecting beam 77 is installed on the inner side of the gear ring 76, and a sweeping brush 78 is installed on the connecting beam 77. The sweeping brush 78 abuts against the outer surface of the air intake net 22. Spring blocks 79 are slidably connected to both ends of the connecting beam 77, and a part of the spring block 79 is slidably connected to the inside of the gear ring 76. Two third springs 791 are symmetrically installed inside the gear ring 76, and the spring block 79 is elastically connected to the gear ring 76 through the third spring 791. A top head 792 is installed on the side of the spring block 79, and the top head 792 abuts against the protrusion 23.

[0044] When external air enters the ventilation chamber 21 through the air inlet net 22, some impurities will adhere to the air inlet net 22, which may easily cause the air inlet net 22 to be blocked, reduce the air intake, and thus reduce the heat dissipation efficiency. Therefore, the surface of the air inlet net 22 needs to be cleaned regularly. During the rising and falling process of the lifting plate 43, the connecting rod 71 will drive the rotating wheel 72 to rotate, thereby driving the gear 74 to rotate in the outer shell 75 through the long rod 73, and then driving the gear ring 76 to rotate, and the gear ring 76 drives the connecting beam 77 to rotate, and the sweeping brush 78 on the connecting beam 77 moves in a circular motion to scrape the dust on the outer wall of the air inlet net 22, so that the air inlet net 22 remains clean and breathable, and the air intake is maintained. While the connecting beam 77 moves in a circular motion, the top 792 on the elastic block 79 slidably connected at both ends of the connecting beam 77 intermittently contacts the several protrusions 23 on the outer edge of the air inlet net 22. When the top head 792 contacts the protrusion 23, the spring block 79 slides in the direction away from the air inlet mesh 22, compressing the third spring 791 inside the gear ring 76; when the top head 792 does not contact the protrusion 23, under the elastic force of the third spring 791, the spring block 79 quickly resets, driving the top head 792 to hit the air inlet mesh 22, generating vibration, accelerating the falling of dust on the surface of the air inlet mesh 22, and further improving the effect of the cleaning mechanism 7 in cleaning the air inlet mesh 22.
