Description

Technical Field

[0001] The invention relates to the technical field of dry-type transformers, and in particular to a dust-proof and noise-reducing dry-type transformer. Background Art

[0002] At present, the heat dissipation of dry-type transformers is mainly carried out through natural air cooling and forced air cooling. Therefore, it is necessary to open multiple ventilation holes on the transformer casing to facilitate the heat exchange of air. The air often contains a lot of dust. When the dust enters the dry-type transformer, the heat dissipation effect of the dry-type transformer will deteriorate. The transformer can only be cooled by forced air cooling. The transformer will generate relatively large noise when working. If the transformer is installed outdoors in the community, it will seriously affect the normal life of the surrounding residents.

[0003] A dustproof and noise-reducing dry-type transformer shown in Chinese patent announcement number CN116544004B includes a base, a wind sensing mechanism, a circulation mechanism, a dustproof mechanism and a noise reduction mechanism. A shell is fixedly connected to the base, a transformer body is fixedly connected inside the base, a top cover is rotatably connected to the top of the shell, and a rotating tube is rotatably connected inside the shell. This dustproof and noise-reducing dry-type transformer is convenient for automatically sensing the wind direction and driving the rotating tube to rotate, so that natural wind can always flow into the shell through one side of the shell to take away the heat of the transformer body, and blow out through the other side to take away the heat, thereby achieving the purpose of accelerating heat dissipation, and at the same time using wind power to drive the circulation of internal coolant, improving heat dissipation efficiency while not requiring the use of motors and other devices that are easy to generate heat and consume electricity to drive. The above patent can only be installed in single-phase transformers, while the existing dry-type transformers installed outdoors are mostly three-phase transformers, with a small scope of application and unable to cope with most situations. In addition, the equipment lacks an active heat dissipation method with obvious effects, and lacks heat dissipation means when there is no wind or insufficient wind outside. Summary of the invention

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-11The dust-proof and noise-reducing dry-type transformer shown in the figure includes a shell 1 and a transformer body 7, and also includes an internal blower mechanism 2, a self-cleaning mechanism 3, an air induction mechanism 4, a water collection mechanism 5 and a sound insulation mechanism 6 installed in the shell 1. The top of the shell 1 is provided with a horizontal top plate 11, a shielding plate 12 and an inclined top plate 13. The four sides of the shell 1 are composed of two long side plates 14 and two short side plates 15. The horizontal top plate 11 is connected to the long side plates 14 and the inclined top plate 13. The shielding plate 12 is located directly above the horizontal top plate 11. The inclined top plate 13 Two inclined top plates 13 are symmetrically arranged along the length direction of the housing 1, and the inclined direction of the inclined top plate 13 is arranged outward and downward from the center. The internal blower mechanism 2, the self-cleaning mechanism 3 and the air induction mechanism 4 are symmetrically arranged in two groups along the vertical center plane of the housing 1. The internal blower mechanism 2 includes an exhaust assembly 21, a filter element 22, a filter mounting frame 23, a clamping connection assembly 24 and an exhaust assembly 25. The exhaust assembly 21 is arranged at the bottom of the housing 1, and the filter element 22 is filled in the filter mounting frame 23. The filter mounting frame 23 and the filter element 22 are arranged along the vertical center plane. The self-cleaning mechanism 3 is sequentially arranged in the vertical direction and at least two groups are provided. The clamping connection component 24 is installed in the housing 1. The output end of the clamping connection component 24 is transmission-connected with the filter mounting frame 23. The exhaust component 25 is arranged on the top of the housing 1. The exhaust component 21 introduces the outside air into the housing 1 after filtering through the filter element 22. The self-cleaning mechanism 3 is provided with a sealed chamber 31. The sealed chamber 31 is provided with two groups and is respectively located at the upper and lower ends of the exhaust component 21. The sealed chamber 31 can be sealed with the filter mounting frame 23. A horizontal slide is provided in the sealed chamber 31. The movable extrusion plate 311 is used to extrude the filter element 22, the air induction mechanism 4 includes a first air induction component 41 and a second air induction component 42, the first air induction component 41 is installed on the long side plate 14, and the second air induction component 42 is installed on the short side plate 15, the second air induction component 42 and the first air induction component 41 are both connected to the exhaust component 21, the water collecting mechanism 5 includes a water collecting box 51, the sound insulation mechanism 6 includes a shock absorbing component and a sound insulation board, the transformer body 7 is installed in the shell 1 through the shock absorbing component, and the inner wall of the shell 1 is provided with sound insulation cotton.

[0021] When the device shown in the present invention is working, it can guide natural wind into the housing 1 to dissipate heat for the transformer body 7, and can maintain a good ventilation effect while isolating the transformer body 7 from the external environment as a whole, and has dustproof, rainproof, soundproof and self-cleaning functions, and can operate continuously for a long time without maintenance, reducing the transformer body 7 from direct sunlight, direct contact with water vapor, dust, etc., and improving the normal operation time and service life of the transformer body 7 outdoors. The present invention can adapt to a rectangular housing, and can use natural wind energy to dissipate heat, and provide the necessary active heat dissipation function when natural wind energy is insufficient, while achieving environmental protection functions, it can ensure the normal heat dissipation function of the equipment, and can achieve a strong dust removal effect, ensuring the cleanliness of the internal space of the housing 1.

[0022] The first air induction component 41 and the second air induction component 42 are respectively used to guide the wind blowing toward the housing 1 from different directions, and guide the cool wind into the interior of the housing 1, and blow it into the interior of the housing 1 after filtering through the filter element 22 in the filter mounting frame 23, and blow it from the bottom to the top toward the transformer body 7, so as to realize the heat dissipation operation of the transformer body 7. The water collection mechanism 5 can ensure that the housing 1 has a rainproof function, and can guide rainwater into the water collection box 51 for collection. When the natural wind force is insufficient, the exhaust component 21 actively draws air from the outside. After a period of use, the clamping connection component 24 is unlocked to release the sealing connection between the filter element 22 and the filter mounting frame 23 and the exhaust component 21, and the position of the filter element 22 and the filter mounting frame 23 is replaced in the vertical direction, and the unused filter element 22 and the filter mounting frame 23 are connected to the interior of the exhaust component 21, and the replaced filter element 22 and the filter mounting frame 23 are self-cleaned by the self-cleaning mechanism 3. 22 is connected to the sealed chamber 31, and the rainwater collected in the water collecting tank 51 is discharged and introduced into the sealed chamber 31, and then the filter element 22 is flushed by the rainwater. When the sealed chamber 31 is full, the squeezing plate 311 reciprocates horizontally in the sealed chamber 31, that is, the filter element 22 is repeatedly squeezed to transfer the stains into the water, and the water is discharged after it is dirty, and then new rainwater is refilled. This is repeated several times to achieve a self-cleaning effect on the filter element 22. Although the dust in the filter element 22 can be removed at this time, the filter element 22 is in a wet state and needs to be blown dry. The present invention can exhaust the hot air on the top of the shell 1 after the heat dissipation treatment of the transformer body 7 through the self-cleaning mechanism 3, and dry and blow the filter element 22 located in the sealed chamber 31 by introducing the hot air into the sealed chamber 31. The hot air introduced into the sealed chamber 31 is finally discharged directly to the outside of the shell 1, so that the flushing water vapor will not be discharged into the shell 1.

[0023] The sound insulation mechanism 6 can reduce the low-frequency vibration generated by the transformer body 7 during operation through the shock-absorbing component, thereby reducing the generation of noise. The sound insulation board laid inside the shell 1 can further reduce the volume of the noise diffused to the outside.

[0024] The first air induction assembly 41 includes a first guide plate 411 and a second guide plate 412. The first guide plate 411 and the second guide plate 412 are both fixedly installed on the long side plate 14 and are both located on the outside of the long side plate 14. The first guide plate 411 is located on the side of the second guide plate 412 away from the long side plate 14. The first guide plate 411 is gradually away from the long side plate 14 from top to bottom and is tilted. The second guide plate 412 is gradually close to the long side plate 14 from top to bottom and is tilted. The first guide plate 411 and the second guide plate 412 are each provided with a plurality of first guide plates. The guide plate 411 and several second guide plates 412 are arranged alternately with each other, and the long side plate 14 is arranged to be gradually inclined inward from top to bottom. The bottom of the long side plate 14 is connected to the exhaust assembly 21. The second air induction assembly 42 includes a third guide plate 421 and an arc-shaped baffle plate 422. The short side plate 15 is synchronously inclined from the vertical center plane to both sides in the vertical direction. The arc-shaped baffle plate 422 is fixedly installed at both ends of the short side plate 15, and the inner arc surface of the arc-shaped baffle plate 422 faces the short side plate 15. The third guide plate 421 is installed on the side wall of one end of the long side plate 14 close to the short side plate 15.

[0025] When the natural wind blows toward the long side plate 14 of the outer shell 1, the wind direction at this time is defined as forward (backward) wind. The wind can be guided to the bottom of the long side plate 14 through the long side plate 14 and enter the exhaust assembly 21. The first guide plate 411 is used to ensure that external impurities will fall outward due to gravity when falling on it, and will not enter the inner side of the outer shell 1. The second guide plate 412 and the long side plate 14 are both used to gradually guide the forward (backward) wind downward, and finally enable it to be introduced into the exhaust assembly 21. When the natural wind blows sideways toward the short side panel 15 of the outer casing 1, the wind direction at this time is defined as lateral wind. The lateral wind is divided into two streams through the guidance of the short side panel 15 and respectively guided to the long side panels 14 at both ends of the short side panel 15. At this time, the arc-shaped baffle 422 located at the edge of the short side panel 15 blows the wind accurately to the long side panel 14, and guides the wind through the third guide plate 421, guiding the wind to the exhaust assembly 21 at the bottom of the long side panel 14.

The long strip air outlet 214 is fixedly installed on a side close to the transformer body 7, and one end of the internal and external connecting channel 215 is connected to the bottom end of the long side plate 14. The filter telescopic air inlet pipe 212 and the filter telescopic air outlet pipe 213 are both installed At the output end of the clamping connection assembly 24, the filter mounting frame 23 is located between the filter telescopic air inlet pipe 212 and the filter telescopic air outlet pipe 213. Both the filter telescopic air inlet pipe 212 and the filter telescopic air outlet pipe 213 can be sealed and connected to the filter mounting frame 23. The end of the filter telescopic air inlet pipe 212 away from the filter mounting frame 23 is connected to the internal and external connecting channel 215, and the end of the filter telescopic air outlet pipe 213 away from the filter mounting frame 23 is connected to the exhaust pipe 216 and the natural wind connecting pipe 217 respectively. The other ends of the exhaust pipe 216 and the natural wind connecting pipe 217 are both connected to the long strip air outlet 214, and the exhaust pump 211 is arranged on the natural wind connecting pipe 217.

[0027] When the outside wind is strong, the wind is introduced into the long strip air outlet 214 through the internal and external connecting channel 215, the filtering telescopic air inlet pipe 212, the filter core 22, the filtering telescopic air outlet pipe 213, and the natural wind connecting pipe 217 in sequence, and air is blown into the inside of the outer shell 1 from the long strip air outlet 214. When the outside wind is weak or the wind direction cannot be used, the air is pumped into the inside of the outer shell 1 through the vacuum pump 211, and the wind is introduced into the long strip air outlet 214 after passing through the internal and external connecting channel 215, the filtering telescopic air inlet pipe 212, the filter core 22, the filtering telescopic air outlet pipe 213, and the exhaust pipe 216 in sequence. The blowing state is automatically controlled according to actual needs, which can not only meet the heat dissipation needs, but also achieve the effects of energy saving and environmental protection and purifying the air entering the inside of the outer shell 1.

[0028] The clamping connection assembly 24 includes a first mounting frame 241, a lifting sliding frame 242, a first linear driver 243, a clamping plate 244, a transmission plate 245 and a bidirectional screw slide 246. The first mounting frame 241 is fixedly mounted inside the housing 1 and is located between the transformer body 7 and the long side plate 14. The lifting sliding frame 242 is vertically slidably arranged on the first mounting frame 241. The first linear driver 243 is fixedly mounted on the first mounting frame 241.

Then, several filter mounting frames 23 are fixedly mounted on the lifting sliding frame 242 in sequence along the vertical direction, two clamping plates 244 are provided, and a bidirectional screw slide 246 is horizontally fixedly mounted on the bottom of the shell 1. The two clamping plates 244 are respectively located on the two output ends of the bidirectional screw slide 246, and the clamping plate 244 is slidably connected to the first mounting frame 241. The filter telescopic air inlet pipe 212 and the filter telescopic air outlet pipe 213 are both transmission-connected to the clamping plate 244 through the transmission plate 245, and the clamping plate 244 is transmission-connected to the sealing chamber 31.

[0029] When the filter element 22 needs to be switched, the output of the first linear drive 243 drives the lifting slide frame 242 to move vertically on the first mounting frame 241. Before the displacement, the two clamping plates 244 are driven to move away synchronously through the bidirectional screw slide 246. The clamping plates 244 drive the filter telescopic air inlet pipe 212 and the filter telescopic air outlet pipe 213 connected thereto to move synchronously outward away from the filter mounting frame 23 through the transmission plate 245, so that the filter mounting frame 23 and the filter element 22 can be smoothly lifted and lowered. When the new filter mounting frame 23 moves into place, the bidirectional screw slide 246 drives the two clamping plates 244 to reset, and the filter mounting frame 23 is sealed and connected with the filter telescopic air inlet pipe 212 and the filter telescopic air outlet pipe 213 again. When the new filter mounting frame 23 moves into place, the used filter element 22 moves to the cleaning station, and the used filter element 22 is cleaned by the self-cleaning mechanism 3.

One end of the air inlet 32 ​​is arranged at the top air outlet of the shell 1, and the other end of the air inlet 32 ​​is connected to the air inlet pipe 33. The end of the air inlet pipe 33 away from the air inlet 32 ​​is connected to the first sealed connection chamber 312. A one-way solenoid valve is provided on the air inlet pipe 33. The small exhaust fan is connected to the air inlet pipe 33. One end of the discharge pipe 34 is connected to the second sealed connection chamber 313. The other end of the discharge pipe 34 extends to the outside of the shell 1. A one-way solenoid valve is provided on the discharge pipe 34. One end of the water distribution pipe 35 is connected to the water collecting tank 51, and the other end of the water distribution pipe 35 is connected to the first sealed connection chamber 312.

[0031] When the used filter element 22 is self-cleaned, the first sealed connection chamber 312 and the second sealed connection chamber 313 are driven by the clamping plate 244 to move toward the center, and the filter mounting frame 23 located between the first sealed connection chamber 312 and the second sealed connection chamber 313 is connected to form a sealed chamber 31. The rubber sealing strip is used to ensure that the sealed chamber 31 is in a sealed state as a whole, and liquid and gas will not leak into the housing 1. When cleaning, the rainwater collected in the water collection tank 51 is introduced into the water distribution pipe 35. The one-way solenoid valve is used to control the switch of the water distribution pipe 35 and the flow direction of the rainwater. Under the action of gravity, the rainwater is introduced into the sealed chamber 31. 1, the filter element 22 is infiltrated, and the extrusion plate 311 is driven to move back and forth through the output of the second linear drive 314 to realize the cleaning function. The sewage is discharged outward through the discharge pipe 34. After the cleaning is completed, the small exhaust fan is used for exhaust. The hot air flows into the air inlet 32 ​​and the air inlet pipe 33 from the top of the shell 1, and then enters the inside of the sealed chamber 31. After passing through the filter element 22 in the sealed chamber 31, it is discharged from the discharge pipe 34. The hot air is continuously dried and blown to dry the filter element 22. In this process, the filter element 22 gradually restores its adsorption capacity for impurities such as dust and moisture, plays a self-cleaning function, and can improve the function of the equipment to be maintenance-free for a long time outdoors.

[0032] The water collecting mechanism 5 also includes a water diversion trough 52, a water inlet pipe 53, a first water outlet pipe 54 and a second water outlet pipe 55. A liquid level sensor is provided inside the water collecting tank 51. The water diversion trough 52 is installed at the lowest end of the inclined top plate 13. The water diversion trough 52 is inclined. The bottom end of the water diversion trough 52 is connected to the water inlet pipe 53, and the other end of the water inlet pipe 53 is connected to the inside of the water collecting tank 51. One end of the first water outlet pipe 54 is connected to the bottom of the water collecting tank 51, and the other end of the first water outlet pipe 54 passes through the outer wall of the outer shell 1 and is connected to the outside. One end of the second water outlet pipe 55 is connected to the bottom of the water collecting tank 51, and the other end of the second water outlet pipe 55 is connected to two water distribution pipes 35.

[0033] The water storage amount inside the water collecting tank 51 can be detected by a liquid level sensor installed inside the water collecting tank 51. When it rains, rainwater is introduced into the water diversion trough 52 along the inclined top plate 13 and then enters the water collecting tank 51 through the water inlet pipe 53. When the internal water volume is too high, the excess water can be discharged from the water collecting tank 51 through the first water outlet pipe 54. When the self-cleaning mechanism 3 uses the water inside the water collecting tank 51 for flushing, the water in the water collecting tank 51 is introduced into the water distribution pipe 35 through the second water outlet pipe 55.

[0034] The exhaust assembly 25 includes a first mounting plate 251, a first fan 252, an inclined mounting plate 253, a first filter 254, a first shielding frame 255 and a second shielding frame 256. The first mounting plate 251 is fixedly mounted on the bottom of the horizontal top plate 11. The first mounting plate 251 is inclined from top to bottom and is provided with an inclined mounting plate 253 that gradually approaches the transformer body 7. The first fan 252 is mounted on the inclined mounting plate 253. A first air outlet is opened on the horizontal top plate 11. The first filter 254 is fixedly mounted at the first air outlet of the horizontal top plate 11. The first shielding frame 255 is mounted on the top of the horizontal top plate 11. The second shielding frame 256 is mounted on the bottom of the shielding plate 12. There is a breathable gap between the first shielding frame 255 and the shielding plate 12, and there is a breathable gap between the second shielding frame 256 and the horizontal top plate 11.

[0035] During the exhaust process of the shell 1, when the wind force from the outside to the inside of the shell 1 is sufficient, the wind from the bottom to the top is discharged outward through the first air outlet, and then passes through the first filter 254, the first shielding frame 255 and the second shielding frame 256 in sequence before being discharged outward. Since it is an exhaust process, basically no dust will enter the inside of the shell 1 from the first air outlet. When the wind force is insufficient, the first fan 252 is turned on, and the low-power first fan 252 can drive the airflow to be discharged outward. The first mounting plate 251 and the inclined mounting plate 253 are used to mount the first fan 252, and ensure that the first fan 252 will not block the circulation of the airflow inside the shell 1 under the natural wind state. The first shielding frame 255 and the second shielding frame 256 are used to block external impurities to prevent the impurities from directly rushing back into the shell 1 when the external airflow is too large.

[0036] The exhaust assembly 25 also includes a third shielding frame 257 and an inner opening shielding frame 258. The third shielding frame 257 is fixedly connected to the first shielding frame 255, and the cross-section of the third shielding frame 257 gradually moves away from the first air outlet from top to bottom. The inner opening shielding frame 258 is fixedly installed at the end of the second shielding frame 256, and the cross-section of the inner opening shielding frame 258 gradually approaches the first air outlet from top to bottom. The third shielding frame 257 and the inner opening shielding frame 258 are connected.

[0037] Under normal operating conditions, the wind inside the shell 1 is discharged from the top of the horizontal top plate 11, and is discharged outward after passing through the first shielding frame 255 and the second shielding frame 256. In order to prevent the wind from entering the shell 1 in the reverse direction from the first shielding frame 255 and the second shielding frame 256 due to excessive external wind speed, a third shielding frame 257 and an inner opening shielding frame 258 are added to the outside. The opening is reversely set through the inner opening shielding frame 258, so that the end outlet of the entire exhaust channel is tilted to point to the shell 1 itself, that is, the air outlet is built-in, and it is difficult for the external wind to flow back into the shell 1.

[0038] A bottom partition 16 is also provided at the bottom of the outer shell 1. A first air inlet port is opened at the bottom of the outer shell 1. A second filter 17 is installed on the first air inlet port. The bottom partition 16 is located directly above the first air inlet port. One end of the air inlet channel 18 passes through the bottom partition 16 and is connected to the first air inlet port. The other end of the air inlet channel 18 is connected to the internal and external connecting channel 215. A one-way valve is provided on the air inlet channel 18.

[0039] The wind from the bottom can enter the interior of the outer shell 1 from the first air inlet port, be filtered through the second filter 17, and then be guided through the bottom partition 16, so that the wind can enter the internal and external connecting channel 215 through the air inlet channel 18, and then carry out subsequent blowing operations, increase the air intake position, increase the air intake volume, and enhance the circulation effect of natural blowing.

[0040] The shock absorbing assembly includes a shock absorbing seat 61, a rubber connecting column 62, a first shock absorber 63, a first connecting plate 64, a second shock absorber 65 and an adjustable telescopic pull rod 66. The shock absorbing seat 61 is installed at the bottom of the shell 1 through the rubber connecting column 62, the transformer body 7 is connected to the shock absorbing seat 61 through the first shock absorber 63, the first connecting plate 64 is connected to the top of the shell 1 through the adjustable telescopic pull rod 66, and the first connecting plate 64 is connected to the top of the transformer body 7 through the second shock absorber 65.

[0041] When the transformer body 7 is shock-absorbed, the bottom of the transformer body 7 is supported and shock-absorbed by the shock-absorbing seat 61, the rubber connecting column 62 and the first shock absorber 63, and the top of the transformer body 7 is shock-absorbed and connected by the first connecting plate 64, the second shock absorber 65 and the adjustable telescopic pull rod 66, so as to improve the shock-absorbing effect, and the distance between the first connecting plate 64 and the transformer body 7 can be adjusted by the adjustable telescopic pull rod 66, so as to adjust the shock-absorbing effect.

[0042] Working principle: The first air induction component 41 and the second air induction component 42 are respectively used to guide the wind blowing toward the housing 1 from different directions, and guide the cool wind into the interior of the housing 1, and then blown into the interior of the housing 1 after being filtered by the filter element 22 in the filter mounting frame 23, and blown toward the transformer body 7 from bottom to top, so as to realize the heat dissipation operation of the transformer body 7. The water collecting mechanism 5 can ensure that the housing 1 has a rainproof function, and can guide rainwater into the water collecting box 51 for collection. When the natural wind force is insufficient, the exhaust component 21 actively draws air from the outside, and the air is pumped into the interior of the housing 1 by the exhaust pump 211. The wind passes through the internal and external connecting channel 215, the filtering telescopic air inlet pipe 212, the filter element 22, the filtering telescopic air outlet pipe 213, and the exhaust pipe 216 in turn, and then is introduced into the long strip air outlet 214. After a period of use, the filter element 22 and the filter mounting frame 23 are released from the sealed connection with the exhaust assembly 21 by unlocking the clamping connection assembly 24, and the positions of the filter element 22 and the filter mounting frame 23 are replaced in the vertical direction, and the unused filter element 22 and the filter mounting frame 23 are connected to the inside of the exhaust assembly 21, and the replaced filter element 22 and the filter mounting frame 23 are self-cleaned through the self-cleaning mechanism 3, and the used filter element 22 is connected to the sealed chamber 31. This process is carried out synchronously during the clamping process by the clamping connection assembly 24, and the rainwater collected in the water collecting tank 51 is discharged and introduced into the sealed chamber 31, and then the filter element 22 is flushed by the rainwater. When the sealed chamber 31 is full, the squeezing plate 311 reciprocates horizontally in the sealed chamber 31, that is, the filter element 22 is repeatedly squeezed to transfer the stains into the water, and the water is discharged after it is dirty, and then new rainwater is refilled, and this is repeated several times to achieve As for the self-cleaning effect of the filter element 22, although the dust in the filter element 22 can be removed at this time, the filter element 22 is in a wet state and needs to be blown dry. The present invention can exhaust the hot air on the top of the shell 1 after the heat dissipation treatment of the transformer body 7 through the self-cleaning mechanism 3, and dry and blow the filter element 22 located in the sealed chamber 31 by introducing the hot air into the sealed chamber 31. The hot air introduced into the sealed chamber 31 is finally directly discharged to the outside of the shell 1, and the sewage is discharged outward through the discharge pipe 34. After cleaning, the small exhaust fan is used for exhaust, and the hot air flows into the air inlet 32 ​​and the air inlet pipe 33 from the top of the shell 1, and then enters the sealed chamber 31. After passing through the filter element 22 in the sealed chamber 31, it is discharged from the discharge pipe 34, and the hot air is continuously dried and blown to dry the filter element 22. In this process, the filter element 22 gradually restores its adsorption capacity for impurities such as dust and moisture, thereby playing a self-cleaning function.The low-power first fan 252 can drive the airflow to be discharged outwardly. The first mounting plate 251 and the inclined mounting plate 253 are used to install the first fan 252 and ensure that the first fan 252 will not block the flow of airflow inside the shell 1 under natural wind conditions. The first shielding frame 255 and the second shielding frame 256 are used to block external impurities. A third shielding frame 257 and an inner opening shielding frame 258 are added to the outside. The opening is reversely set through the inner opening shielding frame 258, so that the end outlet of the entire exhaust channel is tilted to point to the shell 1 itself, that is, the air outlet is built-in, and it is difficult for external wind to flow back into the shell 1.
