[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: a European-style prefabricated transformer that is easy to maintain, including a main body 1, an inspection door 11 installed on the main body 1, a top cover 12 on the top of the main body 1, a snow-clearing component on the top cover 12, and an anti-collision component on the inspection door 11. The snow-clearing component includes a horizontal plate 21 fixedly connected to both sides of the top cover 12, a fixing frame 22 fixedly connected to the top of the horizontal plate 21, a sliding groove 23 opened in the top of the fixing frame 22, a slider 24 connected to the sliding groove 23, a snow-clearing plate 25 fixedly connected to the bottom of the slider 24, a screw 26 connected to the slider 24, and an electric motor fixedly connected to one end of the screw 26. The motor 27 has a screw 26 screwed to a slider 24, a screw 26 rotatably connected to a fixed frame 22, a slider 24 slidably connected to a slide groove 23, a snow removal plate 25 in contact with the top of the top cover 12, and a motor 27 fixedly connected to the fixed frame 22. When the motor 27 is started, it drives the screw 26 to rotate, which in turn drives the slider 24 to slide within the slide groove 23. The slider 24 then moves the snow removal plate 25, which scrapes and cleans the snow accumulated on the top of the top cover 12, preventing snow from accumulating and damaging the top cover 12 and the main body 1. A movable groove 41 is provided at the top of the slide groove 23. A movable block 42 is fixedly connected to the top of the slider 24. The movable block 42 is slidably connected to the movable groove 41. The movement of the slider 24 can drive the movable block 42 to move. The movable block 42 can guide the slider 24, which can improve the stability of the snow removal plate 25 and prevent the slider 24 and the screw 26 from rotating synchronously. A heat dissipation vent 51 is opened on the top of the main body 1. A dustproof net 52 is fixedly connected to the inner wall of the heat dissipation vent 51. A cooling fan 53 is fixedly connected to the bottom of the dustproof net 52. The operation of the cooling fan 53 can dissipate the heat inside the main body 1 through the heat dissipation vent 51, which can reduce the internal temperature of the main body 1. The dustproof net 52 can... To prevent dust from entering the main body 1, electric push rods 61 are fixedly connected to the top two sides of the main body 1. The output end of the electric push rods 61 is fixedly connected to the bottom of the top cover 12. Due to the limited internal space of the main body 1, the electric push rods 61 can push the top cover 12 to move vertically, which can leave space for maintenance of the cooling fan 53 from the top of the main body 1. The mounting bracket 22 is fixedly connected to a protective cover 71 on one side of the motor 27. The protective cover 71 has a heat dissipation hole 72 on one side. The protective cover 71 can cover the motor 27 and protect it. The heat dissipation hole 72 can facilitate the heat dissipation of the motor 27.

[0027] Please see Figure 1 , Figure 5 , Figure 6 as well as Figure 7The anti-collision components include a fixed base 31 fixedly connected to the front of the inspection door 11, a groove 32 opened on one side of the fixed base 31, a guide rod 33 connected to the groove 32, a spring 34 fixedly connected to one end of the guide rod 33, and an anti-collision plate 35 fixedly connected to the other end of the guide rod 33. The guide rod 33 is slidably connected to the groove 32, and the other end of the spring 34 is fixedly connected to the inner wall of the groove 32. When adjacent inspection doors 11 are opened, the anti-collision plates 35 can contact each other. The movement of the anti-collision plate 35 can drive the guide rod 33 to move, which can compress the spring 34 to deform it. The spring 34 can buffer the impact, thereby avoiding the inspection doors 11 from contacting and colliding with each other, preventing the inspection doors 11 from deforming, and improving the service life of the inspection doors 11. A protective pad 81 is provided on one side of the anti-collision plate 35. The protective pad 81 is adhered to the anti-collision plate 35. The protective pad 81 can play a preliminary protection role and can also protect the anti-collision plate 35, so that the anti-collision plate 35 is reduced to wear.

[0028] Working principle: During operation, in heavy snow, motor 27 drives screw 26 to rotate. Screw 26 rotates, causing slider 24 to slide within groove 23. Sliding slider 24 moves snow-clearing plate 25, which scrapes and clears snow from the top of top cover 12, preventing snow accumulation from damaging top cover 12 and main body 1, thus extending their service life. Reversing motor 27 moves snow-clearing plate 25 in the opposite direction to reset it. When maintenance is needed, electric push rod 61 pushes top cover 12 upwards, creating space for access from the top of main body 1. After the cooling fan 53 is inspected, the electric push rod 61 can drive the top cover 12 to move down and reset. At the same time, the inspection door 11 can be opened to inspect the internal components of the main body 1. When adjacent inspection doors 11 are opened, the anti-collision plates 35 can come into contact with each other. The movement of the anti-collision plates 35 can drive the guide rod 33 to move, which can compress the spring 34 to deform it. The spring 34 can buffer the impact, thereby preventing the inspection doors 11 from coming into contact with each other and preventing the inspection doors 11 from deforming. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
