[0010] As a further solution of the present invention, the bottom of the sunshade and water retaining plate is fixedly connected with fixed blocks near the front and rear parts, the bottom of the extension plate is fixedly connected with a rotating block, and the rotating block is rotatably connected to the two fixed blocks.

[0011] As a further solution of the present invention, four first pulleys are fixedly connected to the top of the sunshade and water retaining plate, and the connecting cables are wound around the first pulleys.

[0012] As a further solution of the present invention, a second scraper is fixedly connected between the two first water receiving buckets at the front, and the second scraper is adaptively matched with the heat dissipation fins.

[0013] As a further solution of the present invention, a pair of lifting blocks are fixedly connected to the bottom of both sides of the main body, and a lifting groove is opened on the top of the lifting block, and the lifting groove is adaptively matched with the counterweight ball.

[0014] As a further solution of the present invention, connecting blocks are fixedly connected to the bottom on both sides of the main body, a plurality of top blocks are fixedly connected to the top of the connecting blocks, a plurality of water grooves are opened inside the first water receiving bucket through the bottom, and a water retaining block is rotatably connected to the top of the water groove inside the first water receiving bucket.

[0015] As a further solution of the present invention, the cross-sectional dimension of the water retaining block is larger than the cross-sectional dimension of the water trough, and the cross-sectional dimension of the top block is smaller than the cross-sectional dimension of the water trough.

[0016] The beneficial effects of the present invention are as follows:

[0017] By setting up a sunshade and water retaining plate, a reliable protective barrier is provided for the outdoor transformer. The sunshade and water retaining plate can effectively prevent birds and animals from directly contacting the top of the main body, thereby greatly reducing the risk of short circuit caused by birds and animals staying or touching, ensuring the safety of the transformer when used outdoors, and providing a solid guarantee for the stable operation of the transformer. No matter what kind of harsh outdoor conditions, the transformer can be effectively protected from potential harm caused by birds and animals;

[0018] By setting up a protective cleaning structure, an automatic cleaning guarantee mechanism is added to the outdoor operation of the transformer. When it rains, rainwater will accurately enter the first water receiving bucket along the drainage groove. When the weight of the first water receiving bucket and the rainwater it receives is greater than the counterweight ball, a series of cleaning actions will be triggered. The first water receiving bucket moves down and the counterweight ball moves up. In this process, the downward movement of the first water receiving bucket drives the first scraper to slide down along several drainage grooves, thereby being able to comprehensively clean the surface of the sunshade and water retaining plate. This automatic cleaning method can timely and effectively prevent dirt and other corrosive substances from adhering to the surface of the sunshade and water retaining plate for a long time, thereby preventing the sunshade and water retaining plate from being corroded. In this way, not only the service life of the sunshade and water retaining plate is extended, but also it is ensured that it can always play a good sunshade and water retaining role, providing continuous guarantee for the safe operation of the transformer;

[0019] By setting a limiting structure, the stability and reliability of the outdoor operation of the transformer are further improved. The end of the connecting cable connected to the first water receiving bucket will first pass through the bottom of the second pulley and then pass through the top of the third pulley. This ingenious design allows the first water receiving bucket to be completely located at the bottom of the extension plate. On normal non-rainy days, the extension plate can effectively block dust and debris and other items to prevent them from entering the first water receiving bucket. In this way, there will be no situation where the first water receiving bucket will not receive less rainwater due to debris entering the first water receiving bucket, thereby ensuring that the first water receiving bucket can be lowered normally on rainy days to play its cleaning role. The design of this limiting structure fully considers various factors in the outdoor environment and effectively ensures the normal operation of the transformer cleaning system.

[0020] When the first water bucket moves downward, the second scraper will move downward together. This action effectively cleans the heat sink fins. During the operation of the transformer, the heat sink fins play a vital role in heat dissipation. However, due to the influence of the outdoor environment, the heat sink fins are prone to excessive dust adhesion, which will lead to a decrease in heat dissipation efficiency. The automatic cleaning of the second scraper can timely remove the dust on the heat sink fins to prevent the heat sink fins from affecting the heat dissipation efficiency due to excessive dust adhesion, ensuring that the heat sink fins can dissipate heat normally, providing good heat dissipation guarantee for the stable operation of the transformer, and avoiding various faults that may be caused by poor heat dissipation.

[0021] When the first water receiving bucket carrying rainwater moves down to the position of the top block, the top block will lift and rotate the water retaining block, so that the water trough is opened, and the water inside the first water receiving bucket will flow out, thereby causing the counterweight ball to drop again, and the first water receiving bucket moves up and drives the first water receiving bucket. When the first water receiving bucket moves up to the water retaining block and no longer contacts the top block, the top block will reseal the water trough due to gravity, and a new round of water storage operation will be carried out. This cycle is repeated, and the first water receiving bucket can be driven to move up and down reciprocatingly, thereby automatically and continuously cleaning the heat sink fins and the sunshade water retaining plate mechanical energy.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1 - Figure 8 As shown, a transformer with a safety precaution function comprises a main body 1, the front and rear parts of the main body 1 are both equipped with heat dissipation fins 2, the top of the main body 1 is provided with a protective cleaning structure 3, the protective cleaning structure 3 comprises a sunshade and water baffle 5, the top of the main body 1 is fixedly connected with the sunshade and water baffle 5, the top of the sunshade and water baffle 5 is provided with a plurality of drainage grooves 6 on both sides, the top of the sunshade and water baffle 5 is slidably connected with a first scraper 8 on both sides, four connecting cables 9 are connected through the two first scrapers 8, one end of the two connecting cables 9 near the front and rear parts and the other end of the two connecting cables 9 near the middle are fixedly connected with a first water receiving bucket 10, and the other end of the two connecting cables 9 near the front and rear parts and one end of the two connecting cables 9 near the middle are fixedly connected with a counterweight ball 11.

[0033] When it rains, rainwater will flow along the drainage groove 6 into the first water receiving bucket 10. When the weight of the first water receiving bucket 10 and the rainwater it receives is greater than the counterweight ball 11, the first water receiving bucket 10 moves downward and the counterweight ball 11 moves upward. The downward movement of the first water receiving bucket 10 drives the first scraper 8 to slide downward along several drainage grooves 6, thereby cleaning the surface of the sunshade and water baffle 5, preventing dirt and other corrosive substances from adhering to the surface of the sunshade and water baffle 5 for a long time, causing the sunshade and water baffle 5 to be corroded, thereby extending the service life of the sunshade and water baffle 5.

[0034] In this embodiment, the weight of the counterweight ball 11 is greater than the weight of the first water receiving bucket 10, and the sunshade and water retaining plate 5 is in an inverted V shape.

[0035] In this embodiment, the bottom of the first scraper 8 is adaptively matched with the plurality of drainage grooves 6 , and the bottom of the first scraper 8 is made of rubber material.

[0036] In this embodiment, a limiting structure 4 is provided on both sides of the bottom of the sunshade and water baffle plate 5, and the limiting structure 4 includes an extension plate 12. A drainage groove 6 is also provided on the top of the extension plate 12. A second water collecting bucket 13 is fixedly connected to the front and rear parts of the bottom of the extension plate 12. A plurality of arc-shaped telescopic rods 16 are fixedly connected between the bottom of the sunshade and water baffle plate 5 and the bottom of the extension plate 12. A spring 17 is fixedly connected to the outer surface of the arc-shaped telescopic rod 16 between the bottom of the sunshade and water baffle plate 5 and the bottom of the extension plate 12. Two second pulleys 14 are symmetrically installed at the front and rear of the bottom of the extension plate 12, and a third pulley 15 is symmetrically installed at the front and rear of the bottom of the extension plate 12 and is located on the side of the second pulley 14.

[0037] The end of the connecting cable 9 connected to the first water receiving bucket 10 will first pass through the bottom of the second pulley 14 and then pass through the top of the third pulley 15, so that the first water receiving bucket 10 is completely located at the bottom of the extension plate 12, so that on normal non-rainy days, dust, debris and other items will not enter the interior of the first water receiving bucket 10, but will only be blocked by the extension plate 12. Therefore, it is prevented that debris enters the interior of the first water receiving bucket 10, resulting in a reduction in the amount of rainwater that the first water receiving bucket 10 can receive, thereby shortening the descending distance of the first water receiving bucket 10.

[0038] When it rains, rainwater is guided to the interior of the second water receiving bucket 13 through the drainage groove 6. When the weight of the water received by the second water receiving bucket 13 and its own weight are greater than the elastic force of the spring 17, the extension plate 12 starts to rotate until it rotates to a vertical state. At this time, the rainwater can enter the interior of the first water receiving bucket 10 again.

[0039] In this embodiment, the bottom of the sunshade and water retaining plate 5 is fixedly connected with fixed blocks 18 near the front and rear parts, and the bottom of the extension plate 12 is fixedly connected with a rotating block 19 , which is rotatably connected to the two fixed blocks 18 .

[0040] In this embodiment, four first pulleys 7 are fixedly connected to the top of the sunshade and water retaining plate 5 , and the connecting cable 9 is wound around the first pulley 7 .

[0041] In this embodiment, a second scraper 23 is fixedly connected between the two first water receiving buckets 10 at the front, and the second scraper 23 is adaptively matched with the heat dissipation fins 2 .

[0042] When the first water receiving bucket 10 moves downward, the second scraper 23 is driven to move downward together to clean the heat dissipating fins 2, thereby preventing the heat dissipating fins 2 from being adhered to too much dust, resulting in a decrease in heat dissipation efficiency, thereby ensuring that the heat dissipating fins 2 can dissipate heat normally.

[0043] In this embodiment, a pair of lifting blocks 20 are fixedly connected to the bottom of both sides of the main body 1 , and a lifting groove is opened on the top of the lifting block 20 , which is adaptively matched with the counterweight ball 11 .

[0044] In this embodiment, connecting blocks 21 are fixedly connected to the bottom of both sides of the main body 1, and a plurality of top blocks 22 are fixedly connected to the top of the connecting blocks 21. A plurality of water grooves 24 are opened inside the bottom of the first water receiving bucket 10, and a water retaining block 25 is rotatably connected to the top of the water groove 24 inside the first water receiving bucket 10.

[0045] When the first water receiving bucket 10 carrying rainwater moves down to the position of the top block 22, the top block 22 will lift and rotate the water retaining block 25, so that the water trough 24 is opened, and the water inside the first water receiving bucket 10 will flow out, thereby causing the counterweight ball 11 to drop again, and the first water receiving bucket 10 moves up and drives it. When the first water receiving bucket 10 moves up to the point where the water retaining block 25 is no longer in contact with the top block 22, the top block 22 will reseal the water trough 24 due to gravity factors, and perform a new round of water storage operations. This cycle is repeated, and the first water receiving bucket 10 can be driven to move up and down reciprocatingly, thereby automatically and continuously performing mechanical energy cleaning operations on the heat sink 2 and the sunshade water retaining plate 5.

[0046] In this embodiment, the cross-sectional dimension of the water retaining block 25 is larger than the cross-sectional dimension of the water passage 24 , and the cross-sectional dimension of the top block 22 is smaller than the cross-sectional dimension of the water passage 24 .

[0047] It should be noted that the present invention is a transformer with a safety precaution function. When in use, the sunshade and water baffle 5 can prevent birds and animals from directly contacting the top of the main body 1, thereby preventing a short circuit, thereby ensuring the safety of the transformer when used outdoors.

[0048] When it rains, rainwater will flow along the drainage groove 6 into the first water receiving bucket 10. When the weight of the first water receiving bucket 10 and the rainwater it receives is greater than the counterweight ball 11, the first water receiving bucket 10 moves downward and the counterweight ball 11 moves upward. The downward movement of the first water receiving bucket 10 drives the first scraper 8 to slide downward along several drainage grooves 6, thereby cleaning the surface of the sunshade and water baffle 5, preventing dirt and other corrosive substances from adhering to the surface of the sunshade and water baffle 5 for a long time, causing the sunshade and water baffle 5 to be corroded, thereby extending the service life of the sunshade and water baffle 5.

[0049] The end of the connecting cable 9 connected to the first water receiving bucket 10 will first pass through the bottom of the second pulley 14 and then pass through the top of the third pulley 15, so that the first water receiving bucket 10 is completely located at the bottom of the extension plate 12, so that on normal non-rainy days, dust, debris and other items will not enter the interior of the first water receiving bucket 10, but will only be blocked by the extension plate 12. Therefore, it is prevented that debris enters the interior of the first water receiving bucket 10, resulting in a reduction in the amount of rainwater that the first water receiving bucket 10 can receive, thereby shortening the descending distance of the first water receiving bucket 10.

[0050] When it rains, rainwater is guided to the interior of the second water receiving bucket 13 through the drainage groove 6. When the weight of the water received by the second water receiving bucket 13 and its own weight are greater than the elastic force of the spring 17, the extension plate 12 starts to rotate until it rotates to a vertical state. At this time, the rainwater can enter the interior of the first water receiving bucket 10 again.

[0051] When the first water receiving bucket 10 moves downward, the second scraper 23 is driven to move downward together to clean the heat dissipating fins 2, thereby preventing the heat dissipating fins 2 from being adhered to too much dust, resulting in a decrease in heat dissipation efficiency, thereby ensuring that the heat dissipating fins 2 can dissipate heat normally.

[0052] When the first water receiving bucket 10 carrying rainwater moves down to the position of the top block 22, the top block 22 will lift and rotate the water retaining block 25, so that the water trough 24 is opened, and the water inside the first water receiving bucket 10 will flow out, thereby causing the counterweight ball 11 to drop again, and the first water receiving bucket 10 moves up and drives it. When the first water receiving bucket 10 moves up to the point where the water retaining block 25 is no longer in contact with the top block 22, the top block 22 will reseal the water trough 24 due to gravity factors, and perform a new round of water storage operations. This cycle is repeated, and the first water receiving bucket 10 can be driven to move up and down reciprocatingly, thereby automatically and continuously performing mechanical energy cleaning operations on the heat sink 2 and the sunshade water retaining plate 5.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
