This power transformer is easy to use and can accelerate the air circulation inside and outside the housing through the fan, combined with rainwater evaporation to achieve dual heat dissipation for the transformer body, further improving the efficiency of heat dissipation and cooling of the transformer body. At the same time, the above structure allows the ventilation port to be automatically sealed when heat dissipation and cooling are not required, avoiding the problem of external dust and rainwater easily entering the housing and affecting cleanliness, further improving the dustproof and waterproof effect of this power transformer.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8One embodiment of the present invention is as follows: A power transformer with high heat dissipation efficiency includes a base 1, a housing 2 fixedly connected to the top of the base 1, a collection mechanism 3 provided on the top of the housing 2, a cleaning mechanism 4 provided inside the housing 2, a protective mechanism 5 provided inside the housing 2, a body 6 fixedly connected to the inner wall of the housing 2, and a motor 7 fixedly connected to the top of the body 6. The collection mechanism 3 includes a rainwater shell 301, a hollow block 302, a fan 303, a reciprocating screw 304, a water tank 305, a first moving rod 306, a second moving rod 307, a filter plate 308, an elastic telescopic rod 309, a cooling water pipe 310, a water pump 311, and a heat dissipation plate 312. The rainwater shell 301 is fixedly connected to the top of the housing 2, and the hollow block 302 is fixedly connected to the rainwater shell. At the bottom of 301, a reciprocating screw 304 is fixedly connected to the output end of motor 7, and a fan 303 is fixedly connected to the circumferential surface of the reciprocating screw 304. When the device is in use, motor 7 starts, and the output end of motor 7 drives the reciprocating screw 304 to rotate. The rotation of the reciprocating screw 304 drives the fan 303 to start. At this time, the fan 303 can drive the air inside the housing 2 to flow rapidly, increase the air circulation speed, and allow the heat inside the housing 2 to be discharged through the vents. This increases the air circulation speed inside the housing 2, reduces the heat generated by the transformer during power transmission, and prevents damage to the main body 6 due to overheating. The water tank 305 is fixedly connected to the inner wall of the housing 2, and the moving rod 306 is movably connected to the circumferential surface of the reciprocating screw 304. The elastic telescopic rod 309 is fixedly connected to the inner wall of the water tank 305. The second movable rod 307 is fixedly connected to the telescopic end of the elastic telescopic rod 309. The filter plate 308 is fixedly connected to the inner wall of the second movable rod 307. The cooling water pipe 310 is fixedly connected to the surface of the water tank 305. The water pump 311 is fixedly connected to the inner wall of the water tank 305. The heat dissipation plate 312 is fixedly connected to the surface of the main body 6. The hollow block 302 is in contact with the water tank 305. The second movable rod 307 is slidably connected to the inner wall of the water tank 305. The water pump 311 is connected to the cooling water pipe 310. The cooling water pipe 310 is connected to the water tank 305. The hollow block 302 is connected to the rainwater shell 301. The cooling water pipe 310 is fixedly connected to the surface of the main body 6. The rainwater shell 301 can collect excess rainwater on rainy days. Rainwater can enter the water tank 305 through the hollow block 302. Simultaneously, the rotation of the reciprocating screw 304 drives the first moving rod 306 to move up and down reciprocally. After moving a certain distance, the first moving rod 306 contacts and pushes the second moving rod 307, causing it to rise. This rise of the second moving rod 307 moves the filter plate 308. The movement of the filter plate 308 filters the rainwater entering through the hollow block 302 to a certain extent. When the collected rainwater reaches the water tank 305, the water pump 311 starts, pumping the filtered rainwater from inside the water tank 305 into the cooling water pipe 310 through one end.Simultaneously, the other end of the water pump 311 will discharge the rainwater from the cooling water pipe 310 back into the water tank 305, causing the rainwater inside the cooling water pipe 310 to circulate. This circulation of rainwater within the cooling water pipe 310 can cool the transformer body 6, more effectively transferring heat from its surface and reducing its overall temperature, thus improving the transformer's operating efficiency.

[0024] The cleaning mechanism 4 includes a spring rod 401, L-plate 402, L-plate 403, a ventilation plate 404, and a lowering plate 409. The spring rod 401 is fixedly connected to the inner wall of the water tank 305. L-plate 402 and L-plate 403 are fixedly connected to the bottom of the spring rod 401. The ventilation plate 404 is fixedly connected to the inner wall of the housing 2. The lowering plate 409 is fixedly connected to the top of the spring rod 401. When the device is in use, during heavy rain, the rainwater casing 301 collects too much rainwater, causing the water tank 305 to overflow. At this time, the weight of the rainwater will press the lowering plate 409, which in turn presses the telescopic end of the spring rod 401. The device can move downwards. During the downward movement of the lowering plate 409, the telescopic end of the spring rod 401 will drive the L-plate 402 to move downwards. The downward movement of the L-plate 402 will open the opening on the surface of the water tank 305, allowing rainwater inside the water tank 305 to drain out through the opening. At the same time, the spring rod 401 will also drive the L-plate 403 to move downwards. The downward movement of the L-plate 403 will close the ventilation opening at the ventilation plate 404, preventing rainwater from entering the interior of the box 2 during heavy rain and affecting the operation of the main body 6, thus improving the safety of the device and its adaptability to the environment. The cleaning mechanism 4 also includes a connecting rod 405, a rotating column 406, a roller 407, and a brush plate 408. Connecting rod 405 is fixedly connected to the inner wall of connecting rod 405. Rotating column 406 is rotatably connected to the inner wall of connecting rod 405. Roller 407 is fixedly connected to the circumferential surface of rotating column 406. Brush plate 408 is fixedly connected to the circumferential surface of rotating column 406. L-plate 403 contacts the inner wall of housing 2. L-plate 402 contacts water tank 305. Roller 407 contacts heat dissipation plate 312. Simultaneously, during the reciprocating up-and-down movement of connecting rod 306, connecting rod 306 drives connecting rod 405 to move. The movement of connecting rod 405 drives rotating column 406 to move. The movement of rotating column 406 drives roller 407 to move. Roller 407 is in contact with the surface of heat dissipation plate 312. At this time, the movement of the roller 407 will cause it to rotate due to friction. The rotation of the roller 407 will drive the rotating column 406 to rotate, and the rotation of the rotating column 406 will drive the brush plate 408 to rotate. The rotation of the brush plate 408 can clean the surface of the heat sink 312 and the gaps between multiple heat sinks 312, sweeping away dust and debris from the surface of the heat sink 312. If dust, dirt or oil accumulates on the surface of the heat sink 312, it will hinder the heat exchange efficiency of the heat sink, causing heat to not be effectively dissipated, thereby causing the transformer to overheat. Cleaning the heat sink 312 can improve the heat dissipation efficiency of the heat sink 312, improve the working efficiency of the body 6 and the safety of the body 6.

[0025] Working principle: When the device is in use, motor 7 starts, and the output of motor 7 drives the reciprocating screw 304 to rotate. The rotation of the reciprocating screw 304 drives the fan 303 to start. At this time, the fan 303 can drive the air inside the housing 2 to flow rapidly, increase the air circulation speed, and allow the heat inside the housing 2 to be discharged through the vents. This increases the air circulation speed inside the housing 2, reduces the heat generated by the transformer during power transmission, and prevents damage to the main body 6 due to overheating. The rainwater shell 301 can collect excess rainwater on rainy days. The rainwater can enter the interior of the water tank 305 through the hollow block 302. At the same time, the rotation of the reciprocating screw 304 drives the first moving rod 306 to move up and down reciprocally. After moving a certain distance, the first moving rod 306 will contact and squeeze the second moving rod 307. Pushing the second moving rod 307 causes the first moving rod 306 to rise, which in turn moves the filter plate 308. The movement of the filter plate 308 filters the rainwater entering through the hollow block 302 to a certain extent. When the collected rainwater reaches the inside of the water tank 305, the water pump 311 starts. The water pump 311 discharges the filtered rainwater inside the water tank 305 into the cooling water pipe 310 through one end. At the same time, the other end of the water pump 311 discharges the rainwater from the cooling water pipe 310 back into the water tank 305, causing the rainwater inside the cooling water pipe 310 to circulate. The circulation of rainwater inside the cooling water pipe 310 can cool the main body 6, more effectively transfer the heat from the surface of the main body 6, reduce the overall temperature of the main body 6, and improve the working efficiency of the transformer.

[0026] When the device is in use, during heavy rain, the rainwater casing 301 collects too much rainwater, causing the water tank 305 to overflow. At this time, the gravity of the rainwater will press down on the lowering plate 409. The lowering plate 409 will then press down on the telescopic end of the spring rod 401, causing it to move downwards. During this downward movement, the telescopic end of the spring rod 401 will move L-plate 402 downwards, opening the opening on the surface of the water tank 305. Rainwater inside the water tank 305 can then drain out through this opening. Simultaneously, the spring rod 401 will also move L-plate 403 downwards, closing the ventilation opening at the ventilation plate 404. This prevents rainwater from entering the interior of the casing 2 during heavy rain, affecting the operation of the main body 6, thus improving the device's safety and environmental adaptability. Furthermore, during the reciprocating up-and-down movement of the moving rod 306, the moving rod 306... 06 will drive the connecting rod 405 to move, the movement of the connecting rod 405 will drive the rotating column 406 to move, the movement of the rotating column 406 will drive the roller 407 to move, the roller 407 is in contact with the surface of the heat sink 312, at this time the movement of the roller 407 will cause itself to rotate due to friction, the rotation of the roller 407 will drive the rotating column 406 to rotate, the rotation of the rotating column 406 will drive the brush plate 408 to rotate, the rotation of the brush plate 408 can clean the surface of the heat sink 312 and the gaps between multiple heat sinks 312, sweeping off the dust and debris on the surface of the heat sink 312. If dust, dirt or oil accumulates on the surface of the heat sink 312, it will hinder the heat exchange efficiency of the heat sink, causing the heat to not be effectively dissipated, thus causing the transformer to overheat. Cleaning the heat sink 312 can improve the heat dissipation efficiency of the heat sink 312, improve the working efficiency of the body 6 and the safety of the body 6.

[0027] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the protective mechanism 5 includes a second connecting rod 501, a long block 502, a spring block 503, an arc block 504, and an arc block 505. The second connecting rod 501 is rotatably connected to the circumferential surface of the rotating column 406. The long block 502 is fixedly connected to the inner wall of the second connecting rod 501. The spring block 503 is fixedly connected to the top of the long block 502. The arc block 504 is fixedly connected to the telescopic end of the spring block 503. The arc block 505 is fixedly connected to the inner wall of the housing 2. When the device is in use, the rotating column 406 will reciprocate up and down. The reciprocating up-and-down movement will cause the connecting rod 2 501 to move, which in turn will cause the long block 502 to move, which in turn will cause the spring block 503 to move. The movement of the spring block 503 will then cause the arc block 1 504 to move. After the arc block 1 504 has moved a certain distance, it will come into contact with the arc block 2 505. The arc block 2 505 will then compress the arc block 1 504 using its own curvature. At this point, the arc block 1 504 will extend and retract due to the spring in the spring block 503. When the arc block 1 504 is no longer in contact with the arc block 2 505, the arc block 1 504 will... 4. The spring of spring block 503 will reset the device. When arc block 504 resets, the movement of arc block 504 will generate a force, which will knock the ventilation opening of the box 2, dislodging dust and debris from the ventilation opening and preventing dust and debris from accumulating in the ventilation opening, affecting the heat dissipation effect inside the box 2, and improving the service life of the device. The protective mechanism 5 also includes a cylinder 506, a waterproof plate 507, and a storage box 508. The cylinder 506 is fixedly connected to the inner wall of the long block 502, the waterproof plate 507 is fixedly connected to the circumference of the cylinder 506, and the storage box 508... The long block 502 is fixedly connected to the inner wall of the housing 2, and the cylinder 506 is slidably connected to the inner wall of the housing 2. The waterproof plate 507 is in contact with the housing 2. At the same time, during the movement of the connecting rod 501, the connecting rod 501 will drive the long block 502 to move. The movement of the long block 502 will drive the cylinder 506 to move. The movement of the long block 502 will drive the waterproof plate 507 to move. After the waterproof plate 507 moves, it can close the ventilation of the housing 2, preventing rainwater and dust from entering the interior of the housing 2 during heavy rain or bad weather, which would affect the main body 6 and increase the usability of the device.

[0028] Working principle: When the device is in use, the rotating column 406 reciprocates up and down. This reciprocating movement of the rotating column 406 drives the connecting rod 501 to move, which in turn drives the long block 502 to move. The movement of the long block 502 then drives the spring block 503 to move. The movement of the spring block 503 then drives the arc block 504 to move. After moving a certain distance, the arc block 504 comes into contact with the arc block 505. The arc block 505, with its curvature, compresses the arc block 504. At this point, the arc block 504 extends and retracts due to the spring in the spring block 503. When the arc block 504 is no longer in contact with the arc block 505, it returns to its original position due to the spring in the spring block 503. When the arc block 504 is reset, its movement generates a force, which knocks on the ventilation opening of the housing 2, dislodging dust and debris from the ventilation opening. This prevents dust and debris from accumulating in the ventilation opening, affecting the heat dissipation effect inside the housing 2, and improving the service life of the device. Simultaneously, as the connecting rod 501 moves, it drives the long block 502 to move. The movement of the long block 502 drives the cylinder 506 to move, which in turn drives the waterproof plate 507 to move. After the waterproof plate 507 moves, it closes the ventilation opening of the housing 2, preventing rainwater and dust from entering the interior of the housing 2 during heavy rain or severe weather, thus affecting the main body 6 and improving the usability of the device.
