Description

Technical Field

[0001] The present application relates to the technical field of automobile charging piles, and in particular to a rainproof charging pile for new energy vehicles. Background Art

[0002] At present, the function of new energy vehicle charging piles is similar to that of gas pumps in gas stations. They can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.), residential parking lots or charging stations. They can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] In order to dissipate heat from internal electronic components, charging piles in the related art generally have holes on the surface for air exchange between the interior and the outside world. However, when it rains, splashing raindrops can easily enter the interior of the electrical cabinet through the holes. The splashing raindrops can easily corrode the electronic components in the electrical cabinet, affecting the service life of the components in the electrical cabinet. In the related art, the heat dissipation holes are directly sealed to prevent raindrops from entering the interior of the electrical cabinet. However, this will result in poor heat dissipation of the electrical cabinet, affecting the normal use of the electrical cabinet, and therefore needs to be improved. Summary of the invention

[0004] The purpose of this application is to provide a rainproof charging pile for new energy vehicles, which has the advantage of reducing rainwater entering the interior of the electrical cabinet when it rains, while maintaining a good heat dissipation effect inside the electrical cabinet, thereby protecting the electronic components in the electrical cabinet and extending the service life of the electrical cabinet.

[0005] The present application provides a new energy vehicle rainproof charging pile adopting the following technical solution: A rainproof charging pile for new energy vehicles comprises a cabinet and heat dissipation holes arranged on the side walls of the cabinet, an oil cylinder is fixedly arranged on the side walls of the cabinet, a sealing plate is slidably arranged on the side walls of the cabinet, the sealing plate is used to seal the heat dissipation holes, and the piston rod of the oil cylinder is connected to the sealing plate; a water collecting box is arranged at the top of the cabinet, a heat transfer pipe is arranged in the cabinet, the top end of the heat transfer pipe is connected to the bottom end of the water collecting box, and the bottom end of the heat transfer pipe passes through the cabinet; a group of rotating shafts are symmetrically rotated on the inner wall of the water collecting box, a cover plate for sealing the water collecting box is arranged on the rotating shaft, a first gear is arranged on the end wall of the rotating shaft, a group of racks are symmetrically arranged on the top end of the sealing plate, and the racks are meshed with the first gear.

[0006] By adopting the above technical solution, when the charging pile is used outdoors and it rains, the piston rod of the oil cylinder extends, and the oil cylinder drives the sealing plate to slide on the side wall of the cabinet. When the sealing plate slides to a position flush with the heat dissipation hole, the sealing plate can seal the heat dissipation hole, thereby reducing the phenomenon of splashing rainwater entering the cabinet through the heat dissipation hole. When the sealing plate slides, it drives the rack to slide in the vertical direction, and the rack abuts against the first gear to drive the first gear to rotate, thereby driving the rotating shaft to rotate, thereby driving the cover plate to rotate away from the water collecting tank. After the cover plate is opened, rainwater will drip into the water collecting tank, and the rainwater will The rainwater is collected in the water collecting box and flows into the heat transfer tube. Under the action of gravity, the rainwater flows in the heat transfer tube. Since the heat transfer tube is arranged in the cabinet, if the components inside the cabinet are working, the heat transfer tube can absorb part of the heat and discharge the heat out of the cabinet through the continuous flow of rainwater. This can achieve the sealing of the heat dissipation holes when it rains and effectively use the rainwater to dissipate the heat inside the cabinet, reduce the entry of rainwater into the electrical cabinet, and maintain a good heat dissipation effect inside the electrical cabinet, thereby protecting the electronic components in the electrical cabinet and extending the service life of the electrical cabinet.

[0007] Optionally, a raindrop sensor is provided on the side wall of the cabinet, the raindrop sensor is electrically connected to a controller, the oil cylinder is electrically connected to the controller, and the controller is used to control the operation of the oil cylinder when the raindrop sensor continuously detects rain.

[0008] By adopting the above technical solution, when it rains, the raindrop sensor can continuously detect rainwater. After receiving the raindrop sensor signal, the controller automatically controls the operation of the oil cylinder, driving the sealing plate close to the heat dissipation hole. After the rain stops, the controller drives the sealing plate away from the heat dissipation hole, and the operation of the oil cylinder is automatically controlled without human operation.

[0009] Optionally, the heat transfer tube includes a plurality of staggered bent tubes and horizontal tubes, the horizontal tube located at the uppermost end is interconnected with the bottom end of the water collecting tank, the bent tube is located between the horizontal tubes, and both ends of the bent tube are interconnected with the horizontal tube; a sealing plate is rotatably arranged in the bent tube, a torsion spring is arranged at the rotating connection between the sealing plate and the bent tube, and the torsion spring drives the sealing plate to seal the bent tube.

[0010] By adopting the above technical solution, when it rains, the oil cylinder drives the cover plate away from the water collecting tank. At this time, rainwater falls into the water collecting tank and enters the heat transfer tube. Due to the provision of the bent tube and the horizontal tube, the time for rainwater to flow in the heat transfer tube is effectively increased, so that the rainwater can better absorb the heat in the cabinet; when the rainwater is small, the pressure of rainwater on the sealing plate is small. At this time, the torsion spring drives the sealing plate to seal the bent tube, and the rainwater stagnates in the heat transfer tube until the sealing plate opens under the action of pressure after a large amount of rainwater accumulates. Therefore, when the rainwater is small, the rainwater gap can be kept in the heat transfer tube, which increases the time for rainwater to absorb heat in the heat transfer tube, thereby improving the heat dissipation effect of the heat transfer tube.

[0011] Optionally, the cover plate includes a connecting plate and an expansion panel, the connecting plate is interconnected with the rotating shaft, a sliding groove is provided on the side of the connecting plate facing the water collecting tank, the expansion panel is slidingly connected to the bottom wall of the sliding groove, a sliding assembly is arranged between the water collecting tank and the cover plate, and the sliding assembly is used to drive the expansion panel to slide in the sliding groove when the rotating shaft rotates.

[0012] By adopting the above technical solution, when the rotating shaft rotates to cause the cover plate to rotate away from the water collecting tank, the sliding assembly drives the expansion panel to slide in the sliding groove, so that the expansion panel continues to move away from the connecting plate. In this way, when the cover plate is unfolded, the expansion panel increases the contact area between the cover plate and the air as a whole, so that when the cover plate is rotated to an inclined state, rainwater drops on the cover plate can flow into the water collecting tank along the cover plate, thereby increasing the cover plate's rainwater recovery effect, which is beneficial to the heat dissipation of the heat transfer tube.

[0013] Optionally, the sliding assembly includes a linkage roller, a connecting rope, an abutment spring and a second gear. The linkage roller is rotatably arranged on the side wall of the water collecting tank, and the second gear is arranged on the end wall of the linkage roller. The second gear and the first gear are meshed with each other, and the diameter of the second gear is smaller than the diameter of the first gear; the connecting rope is wound around the linkage roller, one end of the connecting rope is fixed to the side wall of the linkage roller, and a sliding hole is penetrated through the inner wall of the sliding groove, and the other end of the connecting rope penetrates the sliding hole and extends into the sliding groove to be connected with the end wall of the expansion panel. A plurality of connecting ropes are provided, and the abutment spring is located in the sliding groove and is sleeved on the connecting rope, one end of the abutment spring abuts against the inner wall of the sliding groove, and the other end of the abutment spring abuts against the end wall of the expansion panel.

[0014] By adopting the above technical scheme, when the oil cylinder drives the sealing plate to slide so that the rack abuts against the first gear, the first gear rotates, the first gear abuts against the second gear, driving the second gear and the linkage roller to rotate, and since the diameter of the second gear is smaller than the diameter of the first gear, the linkage roller continuously rotates to disengage the connecting rope from the linkage roller, at which time the abutting spring recovers its deformation, the abutting spring abuts against the end wall of the expansion panel, the connecting rope slides in the sliding hole, driving the expansion panel to continuously slide away from the connecting plate, thereby increasing the contact area between the cover plate surface and the air; and when the oil cylinder drives the sealing plate away from the heat dissipation hole, the first gear and the second gear reverse, driving the connecting rope to continuously wrap around the linkage roller, and at the same time the expansion panel retracts into the sliding groove, ensuring that the two symmetrically arranged cover plates can seal the water collecting tank.

[0015] Optionally, a filter screen is provided in the water collecting tank and below the cover plate.

[0016] By adopting the above technical solution, when the water collecting tank collects rainwater, the filter net can filter impurities, thereby reducing the phenomenon of impurities entering the heat transfer tubes and clogging the heat transfer tubes.

[0017] Optionally, a mounting hole is provided on the end wall of the water collecting tank, a mounting frame is provided in the mounting hole, the filter is provided in the mounting frame, the mounting frame is slidably connected to the inner wall of the water collecting tank, and the mounting frame can seal the mounting hole.

[0018] By adopting the above technical solution, the installation frame is driven to slide, and the installation frame is slid out of the installation hole, so that the filter screen can be taken out from the water collecting tank, which is convenient for replacing and cleaning the filter screen.

[0019] Optionally, a solenoid valve electrically connected to a controller is arranged between the heat transfer tube and the water collecting tank, and the controller is used to control the solenoid valve to open when the raindrop sensor continuously detects rain, and to control the solenoid valve to close when the raindrop sensor does not detect rain. A filter and a high-pressure water gun are arranged on the side wall of the cabinet, and the filter is connected to the water collecting tank, and the high-pressure water gun is connected to the filter.

[0020] By adopting the above technical solution, when it rains, the controller controls the solenoid valve to open, and the rainwater collected in the water collecting tank can flow into the heat transfer tube. As time goes by and due to the slow flow rate of the heat transfer tube, more rainwater will accumulate in the water collecting tank. When the rain stops, the controller controls the solenoid valve to close. At this time, the rainwater cannot enter the heat transfer tube and be discharged. The water collecting tank can collect and store rainwater. The rainwater collected in the water collecting tank can be utilized by using a high-pressure water gun and a filter. Users can use the high-pressure water gun to wash the car while charging, thereby improving the function of the charging pile.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. By arranging a cabinet, a heat dissipation hole, an oil cylinder, a sealing plate, a water collecting tank, a heat transfer pipe, a rotating shaft, a cover plate, a first gear and a rack, when the charging pile is used outdoors and encounters rain, the oil cylinder drives the sealing plate to seal the heat dissipation hole. When the sealing plate slides, the rack drives the first gear to rotate, thereby driving the cover plate to rotate away from the water collecting tank. After the cover plate is opened, rainwater will drip into the water collecting tank, where it will be collected and flow into the heat transfer pipe. Under the action of gravity, rainwater will flow in the heat transfer pipe. Since the heat transfer pipe is arranged in the cabinet, the heat transfer pipe can absorb part of the heat, and the heat will be discharged from the cabinet through the continuous flow of rainwater. The heat dissipation hole is sealed when it rains, and rainwater is effectively used to dissipate heat inside the cabinet, thereby reducing the entry of rainwater into the electrical cabinet and maintaining a good heat dissipation effect inside the electrical cabinet, thereby protecting the electronic components in the electrical cabinet and extending the service life of the electrical cabinet. 2. By setting the bending pipe, bending pipe, sealing sheet and torsion spring, when the oil cylinder drives the cover plate away from the water collecting tank, the bending pipe and the horizontal pipe effectively increase the time for rainwater to flow in the heat transfer pipe, so that the rainwater can better absorb the heat in the cabinet. When the rainwater is small, the pressure of rainwater on the sealing sheet is small. At this time, the torsion spring drives the sealing sheet to seal the bending pipe, and the rainwater stagnates in the heat transfer pipe until the sealing sheet opens under the action of pressure after the rainwater accumulates more. Therefore, when the rainwater is small, the rainwater gap can stay in the heat transfer pipe, which increases the time for rainwater to absorb heat in the heat transfer pipe, thereby improving the heat dissipation effect of the heat transfer pipe; 3. By setting a connecting plate, a connecting plate, a sliding groove, a linkage roller, a connecting rope, an abutment spring and a second gear, when the first gear rotates, the first gear drives the second gear and the linkage roller to rotate. Since the diameter of the second gear is smaller than the diameter of the first gear, the linkage roller rotates continuously to separate the connecting rope from the linkage roller. At this time, the abutment spring recovers its deformation to drive the expansion panel to slide continuously away from the connecting plate, thereby increasing the contact area between the cover plate surface and the air. Therefore, when the cover plate is rotated to an inclined state, rainwater drops on the cover plate can flow into the water collecting tank along the cover plate, thereby increasing the rainwater recovery effect of the cover plate, which is beneficial to the heat dissipation of the heat transfer pipe.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0024] A rainproof charging pile for new energy vehicles, referring to Figure 1 and Figure 2 , including a cabinet 1 and a heat dissipation hole 11 arranged on the side wall of the cabinet 1, a plurality of heat dissipation holes 11 are arranged, an oil cylinder 2 is fixedly arranged on the side wall of the cabinet 1, the length direction of the oil cylinder 2 is arranged along the height direction of the cabinet 1, and a sealing plate 21 is slidably arranged on the side wall of the cabinet 1 through a slide rail. When the charging pile is used outdoors and encounters rain, the piston rod of the oil cylinder 2 extends, and the oil cylinder 2 drives the sealing plate 21 to slide on the side wall of the cabinet 1. When the sealing plate 21 slides to a position flush with the heat dissipation hole 11, the sealing plate 21 can seal the heat dissipation hole 11 to reduce the phenomenon that splashing rainwater enters the interior of the cabinet 1 through the heat dissipation hole 11.

[0025] Reference Figure 1 and Figure 2A water collecting box 12 is fixedly arranged at the top of the cabinet 1. The water collecting box 12 is rectangular. A heat transfer tube 3 is arranged in the cabinet 1. The heat transfer tube 3 is made of aluminum and has the characteristic of good heat conduction. The top of the heat transfer tube 3 is connected to the bottom of the water collecting box 12, and the bottom of the heat transfer tube 3 passes through the cabinet 1. A set of rotating shafts 4 are symmetrically arranged on the inner wall of the water collecting box 12. The length direction of the rotating shaft 4 is arranged along the width direction of the water collecting box 12. A cover plate 5 is fixedly arranged on the rotating shaft 4. The two cover plates 5 can seal the water collecting box 12 when they are in a horizontal state. A first gear 41 is arranged on the end wall of the rotating shaft 4. The first gear 41 is arranged coaxially with the rotating shaft 4. A set of racks 22 are symmetrically fixedly arranged on the top of the sealing plate 21. The length direction of the racks 22 is arranged along the height direction of the cabinet 1. One rack 22 is meshed with a first gear 41, and the other rack 22 is meshed with another first gear 41. When it rains, the sealing plate 21 slides on the side wall of the cabinet 1 toward the water collecting tank 12, driving the rack 22 to slide in the vertical direction. The rack 22 abuts against the first gear 41 to drive the first gear 41 to rotate, thereby driving the rotating shaft 4 to rotate, and then driving the cover plate 5 to rotate away from the water collecting tank 12. After the cover plate 5 is opened, rainwater will drip into the water collecting tank 12, and the rainwater will be collected in the water collecting tank 12 and flow into the heat transfer tube 3. Under the action of gravity, the rainwater flows in the heat transfer tube 3. Since the heat transfer tube 3 is arranged in the cabinet 1, the heat transfer tube 3 can absorb part of the heat, and the heat is discharged from the cabinet 1 through the heat transfer tube 3 through the continuous flow of rainwater, so as to achieve the sealing of the heat dissipation hole 11 when it rains and effectively use the rainwater to dissipate the heat inside the cabinet 1, reduce the rainwater from entering the interior of the electrical cabinet, and maintain a good heat dissipation effect inside the electrical cabinet.

[0026] Reference Figure 2 and Figure 3 The heat transfer tube 3 includes a plurality of staggered bent tubes 31 and horizontal tubes 32. The horizontal tubes 32 are arranged in the horizontal direction. The bent tubes 31 are bent. The horizontal tubes 32 at the top are connected to the bottom of the water collecting tank 12. The bent tubes 31 are located between the horizontal tubes 32. Both ends of the bent tubes 31 are connected to the horizontal tubes 32. After rainwater falls into the water collecting tank 12 and enters the heat transfer tube 3, the bent tubes 31 and the horizontal tubes 32 effectively increase the time for rainwater to flow in the heat transfer tube 3, so that the rainwater can better absorb the heat in the cabinet 1.

[0027] Reference Figure 2 and Figure 3A sealing sheet 33 is rotatably arranged in the bent tube 31, and a torsion spring is arranged at the rotation connection between the sealing sheet 33 and the bent tube 31, and the torsion spring drives the sealing sheet 33 to seal the bent tube 31. When the rainwater is small, the pressure of the rainwater on the sealing sheet 33 is small. At this time, the torsion spring drives the sealing sheet 33 to seal the bent tube 31, and the rainwater stagnates in the heat transfer tube 3 until the sealing sheet 33 opens under the action of pressure after the rainwater accumulates more. Therefore, when the rainwater is small, the rainwater gap can be kept in the heat transfer tube 3, which increases the time for the rainwater to absorb heat in the heat transfer tube 3, thereby improving the heat dissipation effect of the heat transfer tube 3.

[0028] Reference Figure 1 and Figure 4The cover plate 5 includes a connecting plate 51 and an expansion plate 52. The connecting plate 51 is connected and fixed to the rotating shaft 4. A sliding groove 511 is provided on one side of the connecting plate 51 facing the water collecting tank 12. The length direction of the sliding groove 511 is arranged along the length direction of the connecting plate 51. The expansion plate 52 is slidingly connected to the bottom wall of the sliding groove 511 through a slide rail. A sliding assembly is arranged between the water collecting tank 12 and the cover plate 5. The sliding assembly includes a linkage roller 61, a connecting rope 62, an abutment spring 63 and a second gear 64. The linkage roller 61 is rotatably arranged on the side wall of the water collecting tank 12. The length direction of the linkage roller 61 is arranged along the width direction of the water collecting tank 12. The second gear 64 is fixedly arranged on the end wall of the linkage roller 61. The second gear 64 is coaxially arranged with the linkage roller 61. The second gear 64 and the first gear 41 are meshed with each other. The diameter of the second gear 64 is smaller than the diameter of the first gear 41. The connecting rope 62 is wound around the linkage roller 61, one end of the connecting rope 62 is fixed to the side wall of the linkage roller 61, the inner wall of the sliding groove 511 is penetrated with a sliding hole 512, the other end of the connecting rope 62 penetrates the sliding hole 512 and extends into the sliding groove 511 to be connected to the end wall of the expansion panel 52. A plurality of connecting ropes 62 are symmetrically arranged, the abutting spring 63 is located in the sliding groove 511 and sleeved on the connecting rope 62, one end of the abutting spring 63 abuts against the inner wall of the sliding groove 511, and the other end of the abutting spring 63 abuts against the end wall of the expansion panel 52. When the oil cylinder 2 drives the sealing plate 21 to approach the water collecting tank 12, the rack 22 drives the first gear 41 to rotate, and the first gear 41 abuts against the second gear 64, driving the second gear 64 and the linkage roller 61 to rotate. Since the diameter of the second gear 64 is smaller than the diameter of the first gear 41, the linkage roller 61 rotates continuously to make the connecting rope 62 disengage from the linkage roller 61. At this time, the abutment spring 63 recovers its deformation, and the abutment spring 63 abuts against the end wall of the expansion panel 52. The connecting rope 62 slides in the sliding hole 512, driving the expansion panel 52 to slide continuously away from the connecting plate 51, thereby driving the cover plate 5 away from the water collecting tank 12 while increasing the contact area between the surface of the cover plate 5 and the air. Therefore, when the cover plate 5 is rotated to an inclined state, rainwater drops on the cover plate 5 can flow into the water collecting tank 12 along the cover plate 5, thereby increasing the rainwater recovery effect of the cover plate 5, which is beneficial to the heat dissipation of the heat transfer pipe 3. When the oil cylinder 2 drives the sealing plate 21 away from the heat dissipation hole 11, the first gear 41 and the second gear 64 reverse, driving the connecting rope 62 to continuously wrap around the linkage roller 61, and at the same time the expansion panel 52 retracts into the sliding groove 511, ensuring that the two symmetrically arranged cover plates 5 can seal the water collecting tank 12.

[0029] Reference Figure 2A filter screen 7 is provided in the water collecting box 12 and below the cover plate 5. When the water collecting box 12 collects rainwater, the filter screen 7 can filter impurities to reduce the phenomenon that impurities enter the heat transfer tube 3 and block the heat transfer tube 3. A mounting hole 121 is provided on the end wall of the water collecting box 12. A mounting frame 71 is provided in the mounting hole 121. The mounting frame 71 and the mounting hole 121 are adapted to each other to seal the mounting hole 121. The filter screen 7 is fixedly provided in the mounting frame 71. The mounting frame 71 is connected to the inner wall of the water collecting box 12 by a sliding rail. The mounting frame 71 is driven to slide. The mounting frame 71 is slid out of the mounting hole 121, and the filter screen 7 can be taken out of the water collecting box 12, so that the filter screen 7 can be replaced and cleaned conveniently.

[0030] Reference Figure 1 A raindrop sensor 13 is provided on the side wall of the cabinet 1, and the raindrop sensor 13 is electrically connected to the controller. The oil cylinder 2 is electrically connected to the controller. When it rains, the raindrop sensor 13 can continuously detect rainwater. After receiving the signal from the raindrop sensor 13, the controller automatically controls the oil cylinder 2 to work, driving the sealing plate 21 close to the heat dissipation hole 11. After the rain stops, the controller drives the sealing plate 21 away from the heat dissipation hole 11, and the oil cylinder 2 is automatically controlled to work without manual operation.

[0031] Reference Figure 1 and Figure 2 A solenoid valve 8 electrically connected to the controller is provided between the heat transfer tube 3 and the water collecting tank 12. When it rains, the controller controls the solenoid valve 8 to open, and the rainwater collected in the water collecting tank 12 can flow into the heat transfer tube 3. As time goes by and the flow rate of the heat transfer tube 3 is slow, more rainwater will accumulate in the water collecting tank 12. A filter 91 and a high-pressure water gun 92 are provided on the side wall of the cabinet 1. The filter 91 is connected to the water collecting tank 12, and the high-pressure water gun 92 is connected to the filter 91. When the rain stops, the controller controls the solenoid valve 8 to close. At this time, the rainwater cannot enter the heat transfer tube 3 and be discharged. The water collecting tank 12 can collect and store the rainwater. The high-pressure water gun 92 and the filter 91 can use the rainwater collected in the water collecting tank 12. The user can use the high-pressure water gun 92 to wash the car when charging, thereby improving the function of the charging pile.

[0032] The implementation principle of the embodiment of the present application is: When it rains, the raindrop sensor 13 continuously detects rain. At this time, the controller controls the piston rod of the oil cylinder 2 to extend, and the oil cylinder 2 drives the sealing plate 21 to slide on the side wall of the cabinet 1. When the sealing plate 21 slides to a position flush with the heat dissipation hole 11, the sealing plate 21 can seal the heat dissipation hole 11, thereby reducing the phenomenon of splashing rainwater entering the cabinet 1 through the heat dissipation hole 11; and when the sealing plate 21 is sliding, it drives the rack 22 to resist the first gear 41, driving the first gear 41 and the rotating shaft 4 to rotate, thereby driving the cover plate 5 to rotate away from the water collecting tank 12. After the cover plate 5 is opened, rainwater will drip into the water collecting tank 12, and the rainwater will be collected in the water collecting tank 12 and The rain flows into the heat transfer tube 3. Under the action of gravity, the rainwater flows in the heat transfer tube 3. Since the heat transfer tube 3 is arranged in the cabinet 1, the flow rate of the rainwater in the heat transfer tube 3 is relatively slow. At this time, if the components in the cabinet 1 are working, the heat transfer tube 3 can absorb part of the heat, and the rainwater continues to flow, and the heat is discharged from the cabinet 1 through the heat transfer tube 3 by flowing, so as to achieve the sealing of the heat dissipation holes 11 when it rains, and effectively use the rainwater to dissipate the heat inside the cabinet 1, reduce the phenomenon of rainwater entering the interior of the electrical cabinet to damage the electronic components, and keep the electrical cabinet with a good heat dissipation effect, so as to protect the electronic components in the electrical cabinet and extend the service life of the electrical cabinet.

[0033] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
