Intelligent safety protection dry-type transformer

Abstract

This invention belongs to the field of transformer technology, specifically an intelligent safety protection dry-type transformer, including a shell. Two fixing plates are symmetrically fixed to the inner wall of the shell, and two first hydraulic cylinders are symmetrically fixed to the top of the fixing plates. A cover plate is fixedly connected to the output ends of the four first hydraulic cylinders. A water storage tank is formed on the top of the cover plate, and the top of the shell extends into the water storage tank. This invention provides an intelligent safety protection dry-type transformer. The first hydraulic cylinders control the cover plate to move upwards, separating it from the shell. This allows the top of the shell to be unobstructed, facilitating the upward escape of hot air from inside the shell, thus helping the transformer dissipate heat better. Furthermore, when the inside of the shell is humid, the hot air heated by the heating wire dries the inside of the shell, and the resulting water vapor can be discharged along the top of the shell, preventing the water vapor from condensing again as the temperature drops, thus avoiding secondary damage to the transformer's interior.

Description

Technical Field

[0001] This invention belongs to the field of transformer technology, specifically a smart safety protection dry-type transformer. Background Technology

[0002] Dry-type transformers are power transformers used for power distribution and conversion. They are characterized by the absence of liquid insulating medium between the windings and the core, instead using solid or dry insulating materials. This reduces fire and environmental risks, making them particularly useful in locations requiring higher safety standards, such as buildings and underground facilities. Furthermore, because they do not contain insulating oil, dry-type transformers eliminate the risk of oil leakage, which also results in typically lower maintenance costs.

[0003] However, some dry-type transformers are installed outdoors. In the hot summer, the internal temperature of outdoor dry-type transformers is prone to rise, and ordinary radiators cannot effectively cool them. Furthermore, it is not convenient to make reasonable use of rainwater when it rains, resulting in insufficient cooling effect of rainwater on dry-type transformers. Secondly, if moisture condenses inside existing dry-type transformers, it is impossible to effectively remove the moisture. Drying methods can only vaporize the moisture into water vapor. As the internal temperature drops, the saturated water vapor pressure decreases, and the water vapor will condense back into water droplets, adhering to the iron core, coils, and shell, causing secondary damage to the dry-type transformer.

[0004] Therefore, the present invention provides an intelligent safety protection dry-type transformer. Summary of the Invention

[0010] Preferably, the bottom of the cover plate is symmetrically and fixedly connected to two guide plates, both of which are installed at an angle and fixedly connected to each other.

[0011] Preferably, a first connecting plate is fixedly connected to both sides of the cover plate, a protective cover is provided above the cover plate, two second connecting plates are symmetrically fixedly connected to the inner wall of the protective cover, two sliding shafts are symmetrically slidably connected to the inner walls of the two first connecting plates, a limit block is fixedly connected to the top of each of the two sliding shafts, the bottom of each of the two sliding shafts is fixedly connected to the second connecting plate, a second spring is sleeved on the outer wall of each of the two sliding shafts, the top of the second spring is fixedly connected to the first connecting plate, the bottom of the second spring is fixedly connected to the second connecting plate, the top of the protective cover is set as a symmetrical inclined surface, a first filter plate is fixedly connected to the symmetrical inclined surface of the top of the protective cover, two side plates are symmetrically fixedly connected to the inclined surface of the top of the protective cover with the first filter plate as the center, and a vibration component is provided at the bottom of the first filter plate.

[0012] Preferably, the vibration assembly includes two supports, which are symmetrically fixedly installed at the bottom of the first filter plate. A top plate is fixedly connected to the bottom of each of the two supports. Two mounting grooves are symmetrically opened on the outer wall of the housing above the water inlet. A protrusion is slidably connected to the inner wall of the mounting groove. One side of the protrusion is set as a symmetrical inclined surface. Two first springs are symmetrically fixedly connected to the other side of the protrusion. One end of each of the two first springs is fixedly connected to the housing. The elastic force of the first spring is greater than that of the second spring. The protrusion and the top plate cooperate with each other.

[0013] Preferably, a plurality of heat dissipation fins are fixedly connected at equal intervals to the inner wall of the water storage plate, the top of the heat dissipation fins is flush with the top of the water storage plate, two sleeves are symmetrically fixedly connected to the outer wall of the shell, one side of the heat dissipation fins extends into the interior of the sleeve and is fixedly connected to the sleeve, and two connecting pipes are symmetrically fixedly connected to the outer wall of the air intake pipe, the ends of the two connecting pipes extend into the interior of the two sleeves respectively.

[0014] Preferably, a plurality of sponge pads are fixedly connected at equal intervals to the inner wall of the casing and above the heat dissipation fins, and adjacent sponge pads are installed in a staggered manner.

[0015] Preferably, a second filter plate is fixedly connected to the top of the housing, the second filter plate is installed at an angle, and a groove is provided at the bottom of the cover plate to cooperate with the second filter plate.

[0016] The beneficial effects of this invention are as follows: 1. The intelligent safety protection dry-type transformer of the present invention uses a first hydraulic cylinder to control the cover plate to move upward, so that the cover plate is separated from the shell, thereby making the top of the shell unobstructed, which facilitates the upward escape of hot air inside the shell, helping the transformer to dissipate heat better. When the inside of the shell is humid, the hot air heated by the heating wire dries the inside of the shell, and the water vapor generated by drying can be discharged along the top of the shell, avoiding the water vapor from condensing again as the temperature drops, which would cause secondary damage to the inside of the transformer.

[0017] 2. The intelligent safety protection dry-type transformer of the present invention can store rainwater through a water storage tank. After the rain stops and the weather warms up, the cover plate is moved upward again by the first hydraulic cylinder to make the top of the shell unobstructed. At the same time, the lower position inside the water storage tank moves to the water inlet. At this time, the rainwater stored inside the water storage tank can enter the water inlet tank along the water inlet and enter each water storage chamber in sequence. Each water storage chamber inside the shell can be filled with rainwater to help the shell dissipate heat.

[0018] 3. The intelligent safety protection dry-type transformer of the present invention, when there is water accumulation on the ground where the transformer is placed, controls the piston plate to move upward in the water inlet tank through the second hydraulic cylinder. Under the pulling action of the piston plate, the hose and water filter can extract the water accumulation on the ground. The water filter can filter the extracted water to avoid extracting dirt. The extracted water enters several water storage chambers in sequence to help cool the shell. After the water accumulation on the ground is consumed, the water in the water storage tank is used. In this way, rainwater is used to cool the shell in a reasonable way, and the utilization efficiency of natural resources is better.

[0019] 4. The intelligent safety protection dry-type transformer of the present invention can filter rainwater entering the water storage tank through the first filter plate. When the control cover moves downward, the cooperation between the protrusion and the top plate can drive the protective cover to vibrate downward, thereby shaking off the dust and fallen leaves accumulated on the first filter plate. The dust and fallen leaves can slide down the inclined surface at the top of the first filter plate, avoiding the dust and fallen leaves from clogging the first filter plate and affecting the water intake.

[0020] 5. The intelligent safety protection dry-type transformer of the present invention, through the setting of heat dissipation fins, can increase the contact area between the shell and the surrounding air. By expanding the heat dissipation surface, the heat inside the shell can be transferred to the air more quickly, thereby effectively reducing the temperature inside the shell. At the same time, the heat dissipation fins can also cool the rainwater accumulated in the water storage chamber, preventing the rainwater from heating up too quickly. When the exhaust fan is started, the end of the connecting pipe begins to intake air. The set sleeve can concentrate the air and form a downward airflow inside the sleeve. By increasing the air velocity near the heat dissipation fins and the shell, the heat dissipation fins and the shell can be cooled better. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 11 As shown, this invention provides a technical solution: an intelligent safety protection dry-type transformer, comprising a housing 1. Two fixing plates 2 are symmetrically fixedly connected to the inner wall of the housing 1. Two first hydraulic cylinders 3 are symmetrically fixedly connected to the top of the fixing plates 2. A cover plate 4 is fixedly connected to the output ends of the four first hydraulic cylinders 3. A water storage tank 5 is provided on the top of the cover plate 4. The top of the housing 1 extends into the interior of the water storage tank 5. An exhaust fan 6 is fixedly connected to the bottom of the housing 1. An air inlet pipe 7 is fixedly connected to the input end of the exhaust fan 6. An air outlet pipe 8 is fixedly connected to the output end of the exhaust fan 6. The top of the air outlet pipe 8 extends into the interior of the housing 1. A mounting plate 9 is fixedly connected to the outer wall of the air outlet pipe 8. An air outlet groove 10 is provided inside the mounting plate 9. A heating wire 11 is fixedly connected inside the air outlet groove 10. A cooling component is provided inside the housing 1. The cooling component includes a water inlet 13, which is located within the housing 1. Inside the shell 1, several water storage chambers 17 are equidistantly arranged. A connecting groove 18 is provided between two adjacent water storage chambers 17. A water outlet groove 14 is provided at the bottom of the lowest water storage chamber 17 inside the shell 1. The uppermost water storage chamber 17 is connected to the water inlet groove 13. A cooling unit is provided inside the water storage chamber 17. The cooling unit includes a water storage plate 19, which is fixedly installed inside the water storage chamber 17. The water storage plate 19 is concave. Water inlets 43 are provided on both sides of the outer wall of the shell 1. The water inlets 43 are located inside the water storage groove 5 and are connected to the water inlet groove 13. Two sets of water circulation units are symmetrically arranged at the bottom of the shell 1. Each set of water circulation units includes two hoses 15. The two hoses 15 are symmetrically fixedly installed at the bottom of the shell 1. One end of the hose 15 extends into the interior of the water outlet groove 14, and the other end of the hose 15 is fixedly connected to a water filter 16.

[0026] Through the above technical solution, in the hot summer, the first hydraulic cylinder 3 controls the cover plate 4 to move upward, separating the cover plate 4 from the housing 1. This allows the top of the housing 1 to be unobstructed, facilitating the upward escape of hot air inside the housing 1, thus helping the transformer to dissipate heat better. Furthermore, the cover plate 4 effectively prevents dust, leaves, and other debris from falling into the housing 1. The exhaust fan 6 is activated, causing air to enter through the intake pipe 7 and exit through the exhaust pipe 8. The air exiting the exhaust pipe 8 flows upward along the exhaust groove 10, further improving airflow within the housing 1 and enhancing heat dissipation. In rainy weather... In the given environment, the first hydraulic cylinder 3 controls the cover plate 4 to move downwards, making the cover plate 4 fit with the shell 1 to prevent rainwater from falling into the shell 1. When the cover plate 4 fits with the shell 1, the water inlet 43 is located at a higher position inside the water storage tank 5, allowing the water storage tank 5 to collect rainwater. After the rain stops and the weather warms up, the first hydraulic cylinder 3 controls the cover plate 4 to move upwards again, making the top of the shell 1 unobstructed. At the same time, the lower position inside the water storage tank 5 moves to the water inlet 43. At this time, the rainwater collected inside the water storage tank 5 can enter the water inlet tank 13 through the water inlet 43. Rainwater flows downwards from 3 and is caught by the water storage plate 19 in the water storage chamber 17, allowing it to accumulate. As the rainwater continues to flow down from the water storage tank 5, once the water storage plate 19 is full, the rainwater overflows along the edge of the water storage plate 19 and flows along the connecting groove 18 to the lower water storage chamber 17. Thus, when the cover plate 4 is opened upwards to dissipate heat from the housing 1, each water storage chamber 17 inside the housing 1 is filled with rainwater, aiding in heat dissipation. After several water storage plates 19 are filled with rainwater, excess rainwater can be discharged along the hose 15 and the filter 16. When the inside of housing 1 is heavily moist, the cover plate 4 is moved upward by the first hydraulic cylinder 3 to make the top of housing 1 unobstructed. The heating wire 11 is activated to heat the air passing through the air outlet 10. At this time, the exhaust fan 6 is activated to blow air upward through the air outlet pipe 8. The hot air can dry the inside of housing 1, and the water vapor generated by drying can be discharged along the top of housing 1 to prevent the water vapor from condensing again as the temperature drops, which would cause secondary damage to the inside of the transformer. After the moisture inside housing 1 is treated, the cover plate 4 is controlled to re-fit with housing 1 to prevent moisture absorption again.

[0027] Specifically, a hollow groove 21 is provided on one side of the water inlet trough 13. A second hydraulic cylinder 22 is fixedly connected to the top of the inner wall of the hollow groove 21. A piston plate 23 is fixedly connected to the output end of the second hydraulic cylinder 22. The piston plate 23 fits against the inner wall of the water inlet trough 13 and the hollow groove 21. A drain groove 24 is provided on the other side of the water inlet trough 13.

[0028] Through the above technical solution, when rainwater in the water storage tank 5 enters the water storage chamber 17, the piston plate 23 is moved to the drainage trough 24 by the second hydraulic cylinder 22. At this time, the inlet trough 13 is unobstructed, and rainwater can flow through the drainage trough 24 into the inlet trough 13. When there is water accumulation on the ground where the transformer is placed, the piston plate 23 is moved downward by the second hydraulic cylinder 22. The air squeezed by the piston plate 23 can be discharged through the hose 15 and the water filter 16. Then, the second hydraulic cylinder... The cylinder 22 controls the piston plate 23 to move upward in the water inlet trough 13. Under the pulling action of the piston plate 23, the hose 15 and the water filter 16 can draw water from the ground. The water filter 16 can filter the drawn water to avoid drawing out dirt. The drawn water enters several water storage chambers 17 in sequence to help cool the shell 1. After the water on the ground is used up, the water in the water storage tank 5 is used. In this way, rainwater is used to cool the shell 1 in a reasonable way, and the utilization efficiency of natural resources is better.

[0029] Specifically, two guide plates 12 are symmetrically fixedly connected to the bottom of the cover plate 4. Both guide plates 12 are installed at an angle and fixedly connected to each other.

[0030] With the above technical solution, when air is blown upward through the air outlet 10, the hot air or moisture inside the shell 1 can be better evaporated by the flow guided by the bottom slope of the two guide plates 12, and the hot air and moisture can be prevented from accumulating at the bottom of the cover plate 4 and not easily dissipating.

[0031] Specifically, a first connecting plate 30 is fixedly connected to both sides of the cover plate 4. A protective cover 39 is provided above the cover plate 4. Two second connecting plates 31 are symmetrically fixedly connected to the inner wall of the protective cover 39. Two sliding shafts 32 are symmetrically slidably connected to the inner walls of the two first connecting plates 30. Limit blocks 34 are fixedly connected to the top of each of the two sliding shafts 32. The bottom of each of the two sliding shafts 32 is fixedly connected to the second connecting plate 31. A second spring 33 is sleeved on the outer wall of each of the two sliding shafts 32. The top of the second spring 33 is fixedly connected to the first connecting plate 30, and the bottom of the second spring 33 is fixedly connected to the second connecting plate 31. The top of the protective cover 39 is set as a symmetrical inclined surface. A first filter plate 40 is fixedly connected to the symmetrical inclined surface of the top of the protective cover 39. Two side plates 42 are symmetrically fixedly connected to the inclined surface of the first filter plate 40. A vibration assembly is provided at the bottom of the first filter plate 40. The vibration assembly includes two supports 35, which are symmetrically fixedly installed at the bottom of the first filter plate 40. A top plate 36 is fixedly connected to the bottom of each of the two supports 35. Two mounting grooves 27 are symmetrically opened on the outer wall of the housing 1 above the inlet 43. A protrusion 29 is slidably connected to the inner wall of the mounting groove 27. One side of the protrusion 29 is set as a symmetrical inclined surface. Two first springs 28 are symmetrically fixedly connected to the other side of the protrusion 29. One end of each of the two first springs 28 is fixedly connected to the housing 1. The elastic force of the first spring 28 is greater than that of the second spring 33. The protrusion 29 and the top plate 36 cooperate with each other.

[0032] Through the above technical solution, the symmetrically arranged first filter plates 40 can filter the rainwater entering the water storage tank 5, preventing dust, fallen leaves and other dirt from entering the water storage tank 5 and causing blockage. The two side plates 42 form a lateral enclosure for the rainwater falling on the first filter plates 40, preventing the rainwater from overflowing to both sides during the filtration process, and ensuring that the rainwater is filtered along the inclined direction of the first filter plates 40. When the cover plate 4 is moved downward by the first hydraulic cylinder 3, it drives the first connecting plate 30 to move downward, causing the second spring 33 to move downward, pushing the second connecting plate 31 to move downward, causing the protective cover 39 to move downward, and driving the top plate 36 to move downward. When the top plate 36 moves to the protrusion 29, it is blocked by the inclined surface of the top of the protrusion 29. At this time, the cover plate 4 and the first connecting plate 30 continue to move downward, while the second connecting plate 31 and the protective cover 39 stop moving downward due to the obstruction of the inclined surface of the top of the protrusion 29 and are pressed together. When the second spring 33 is compressed to its limit, as the cover plate 4 continues to move downward, the inclined surface of the top of the protrusion 29 is pressed by the top plate 36, and the protrusion 29 moves into the mounting groove 27, pressing the first spring 28. When the top plate 36 moves downward away from the protrusion 29, it loses the pressure of the top plate 36. Under the action of the first spring 28, the protrusion 29 is reset and loses the pressure of the protrusion 29. Under the action of the second spring 33, the second connecting plate 31 moves downward, causing the sliding shaft 32 to move downward, and causing the limiting block 34 to move downward. When the limiting block 34 hits the first connecting plate 30 downward, the limiting block 34 stops moving downward, causing the second connecting plate 31 and the protective cover 39 to vibrate downward. This facilitates the shaking off of dust and fallen leaves accumulated on the first filter plate 40, allowing the dust and fallen leaves to slide down the inclined surface at the top of the first filter plate 40, preventing dust and fallen leaves from clogging the first filter plate 40 and affecting water intake.

[0033] Specifically, a number of heat dissipation fins 20 are fixedly connected at equal intervals on the inner wall of the water storage plate 19. The top of the heat dissipation fins 20 is flush with the top of the water storage plate 19. Two sleeves 25 are symmetrically fixedly connected to the outer wall of the shell 1. One side of the heat dissipation fins 20 extends into the interior of the sleeve 25 and is fixedly connected to the sleeve 25. Two connecting pipes 37 are symmetrically fixedly connected to the outer wall of the air intake pipe 7. The ends of the two connecting pipes 37 extend into the interior of the two sleeves 25 respectively.

[0034] Through the above technical solution, the heat dissipation fins 20 can increase the contact area between the shell 1 and the surrounding air. By expanding the heat dissipation surface, the heat inside the shell 1 can be transferred to the air more quickly, thereby effectively reducing the temperature inside the shell 1. At the same time, the heat dissipation fins 20 can also cool the rainwater accumulated in the water storage chamber 17, preventing the rainwater from heating up too quickly (this is existing technology and will not be elaborated on here). After the exhaust fan 6 is started, air begins to enter at the end of the connecting pipe 37. The set sleeve 25 can concentrate the air and form a downward airflow inside the sleeve 25. By increasing the airflow velocity near the heat dissipation fins 20 and the shell 1, the heat dissipation fins 20 and the shell 1 can be cooled better.

[0035] Specifically, a number of sponge pads 38 are fixedly connected at equal intervals on the inner wall of the housing 25 and above the heat dissipation fins 20, with adjacent sponge pads 38 being staggered; a second filter plate 41 is fixedly connected to the top of the housing 25, the second filter plate 41 is installed at an angle, and a groove 26 for use with the second filter plate 41 is provided at the bottom of the cover plate 4.

[0036] Through the above technical solution, the second filter plate 41 can filter the air entering the housing 25, preventing dust and other particles from entering the housing 1. When the air enters the housing 25, several staggered sponge pads 38 can absorb the moisture in the air, preventing moisture from entering the housing 1. When it rains, the cover plate 4 can be moved downwards to cooperate with the groove 26 to seal the top of the housing 25, preventing rainwater from wetting the sponge pads 38. When the weather is hot, the cover plate 4 can be moved upwards to allow the sun to dry the moisture absorbed by the sponge pads 38.

[0037] During use, in hot summer weather, the first hydraulic cylinder 3 controls the cover plate 4 to move upwards, separating it from the housing 1. This allows the top of the housing 1 to be unobstructed, facilitating the upward escape of hot air from inside the housing 1 and aiding in better heat dissipation for the transformer. The cover plate 4 also effectively prevents dust, leaves, and other debris from falling into the housing 1. Activating the exhaust fan 6 allows air to enter through the intake pipe 7 and exits through the exhaust pipe 8, which then flows upwards along the exhaust groove 10, further improving airflow and heat dissipation. In rainy conditions, the first hydraulic cylinder 3 controls the cover plate 4 to move downwards, fitting it snugly against the housing 1 to prevent rainwater from entering. Once the cover plate 4 is snugly against the housing 1... The inlet 43 is located at a higher position inside the water storage tank 5. The water storage tank 5 can collect rainwater. After the rain stops and the weather warms up, the first hydraulic cylinder 3 controls the cover plate 4 to move upwards again, ensuring the top of the housing 1 is unobstructed. Simultaneously, the lower position inside the water storage tank 5 moves to the inlet 43. At this time, the rainwater collected inside the water storage tank 5 can enter the inlet tank 13 along the inlet 43. The rainwater entering the inlet tank 13 flows downwards and is caught by the water storage plate 19 in the water storage cavity 17, allowing the rainwater to accumulate in the water storage cavity 17. As the rainwater continues to flow downwards in the water storage tank 5, when the water storage plate 19 is full, the rainwater overflows along the edge of the water storage plate 19 and flows along the connecting groove 18 to the lower water storage cavity 17, thus receiving... When the cover plate 4 is opened upwards to dissipate heat from the housing 1, each water storage chamber 17 inside the housing 1 can be filled with rainwater, helping the housing 1 to dissipate heat. After several water storage plates 19 are filled with rainwater, excess rainwater can be discharged from the housing 1 along the hose 15 and the water filter 16. When the moisture inside the housing 1 is heavy, the cover plate 4 is moved upwards by the first hydraulic cylinder 3 to make the top of the housing 1 unobstructed. The heating wire 11 is activated to heat the air passing through the air outlet 10. At this time, when the exhaust fan 6 is activated to blow air upwards through the air outlet 8, the hot air can dry the inside of the housing 1, and the water vapor generated during drying can be discharged along the top of the housing 1, avoiding the water vapor from condensing again as the temperature drops, which would cause secondary damage to the inside of the transformer. After the moisture inside the housing 1 is treated, the control cover 4 re-fits the housing 1 to prevent re-absorption of moisture. When air is blown upward through the air outlet 10, the flow is guided by the inclined surfaces at the bottom of the two guide plates 12, which can better evaporate the heat or moisture inside the housing 1 and prevent the heat and moisture from accumulating at the bottom of the cover 4 and being difficult to disperse. When the rainwater in the control water storage tank 5 enters the water storage chamber 17, the piston plate 23 is moved into the drainage tank 24 by the second hydraulic cylinder 22. At this time, the water inlet tank 13 is in a clear state, and the rainwater can flow through the drainage tank 24 into the water inlet tank 13. When there is standing water on the ground where the transformer is placed, the piston plate 23 is moved downward by the second hydraulic cylinder 22, and the gas squeezed by the piston plate 23 can be discharged through the hose 15 and the water filter 16.Subsequently, the piston plate 23 is moved upward in the water inlet trough 13 by the second hydraulic cylinder 22. Under the pulling action of the piston plate 23, the hose 15 and the water filter 16 can extract the water from the ground. The water filter 16 can filter the extracted water to avoid extracting dirt. The extracted water enters several water storage chambers 17 in sequence to help cool the shell 1. After the water on the ground is used up, the water in the water storage tank 5 is used. This makes reasonable use of rainwater to cool the shell 1 and improves the efficiency of natural resource utilization. The first filter plate 40 can filter the rainwater entering the water storage tank 5 to prevent dust, fallen leaves and other dirt from entering the water storage tank 5 and causing blockage. The two side plates 42 form a filter on the rainwater falling on the first filter plate 40. The side-mounted design prevents rainwater from overflowing to both sides during filtration, ensuring that rainwater is filtered along the inclined direction of the first filter plate 40. As the cover plate 4 moves downwards controlled by the first hydraulic cylinder 3, it moves the first connecting plate 30 downwards, causing the second connecting plate 31 to move downwards, which in turn moves the protective cover 39 downwards, causing the top plate 36 to move downwards. When the top plate 36 reaches the protrusion 29, it is blocked by the inclined surface at the top of the protrusion 29. At this point, the cover plate 4 and the first connecting plate 30 continue to move downwards, while the second connecting plate 31 and the protective cover 39 stop moving downwards and compress the second spring 33. When the second spring 33 is compressed to its limit, as the cover plate 4 continues to move downwards, the protrusion 29 is pushed into the mounting groove 27 by the top plate 36, compressing the first spring 28. After plate 36 passes downward through protrusion 29, it loses the pressure of protrusion 29. Under the action of second spring 33, it drives protective cover 39 to vibrate downward, thereby shaking off the dust and fallen leaves accumulated on the first filter plate 40. This allows the dust and fallen leaves to slide down the inclined surface at the top of the first filter plate 40, preventing dust and fallen leaves from clogging the first filter plate 40 and affecting water intake. The heat dissipation fins 20 increase the contact area between the shell 1 and the surrounding air. By expanding the heat dissipation surface, the heat inside the shell 1 can be transferred to the air more quickly, thereby effectively reducing the internal temperature of the shell 1. The heat dissipation fins 20 can also cool the rainwater accumulated in the water storage chamber 17, preventing the rainwater from heating up too quickly. After the exhaust fan 6 is started, the end of the connecting pipe 37 opens. Upon initial air intake, the set-in casing 25 concentrates the air, creating a downward airflow within it. This increases the air velocity near the heat dissipation fins 20 and the housing 1, resulting in better cooling of these components. The second filter plate 41 filters the air entering the casing 25, preventing dust and other contaminants from entering the housing 1. Furthermore, once air enters the casing 25, several staggered sponge pads 38 absorb moisture, preventing it from entering the housing 1. During rain, the cover plate 4 moves downwards, engaging with the groove 26 to seal the top of the casing 25, preventing rainwater from wetting the sponge pads 38. In hot weather, the cover plate 4 moves upwards, allowing sunlight to dry the moisture absorbed by the sponge pads 38.
