[0022] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0023] See Figures 1 to 5 This embodiment discloses a transformer top protection device with buffer function, including a buffer mechanism 2 and a protection mechanism 3 installed on the top of the transformer 1.

[0024] The buffer mechanism 2 includes a buffer frame 25 movably mounted on top of the transformer 1. The buffer frame 25 is slidably mounted on top of the transformer 1 and can slide vertically. The buffer frame 25 has several limiting grooves, and the top of the transformer 1 has several limiting rods. The vertical sliding cooperation between the limiting grooves and the limiting rods guides the vertical movement of the buffer frame 25. In this embodiment, four limiting grooves are provided on the buffer frame 25. Front limiting grooves are provided on the two connecting blocks 23 on the front side of the buffer frame 25, and rear limiting grooves are provided at the left and right ends on the rear side of the buffer frame 25. Correspondingly, four limiting rods are provided on top of the transformer 1, including two first limiting rods 21 located on the rear side and two second limiting rods 28 located on the front side. An elastic support structure is provided at the bottom of the buffer frame 25 to provide elastic support.

[0025] The elastic support structure includes two sets of elastic support components arranged opposite each other on the left and right. Each set of elastic support components includes a mounting shaft, two support arms 26, a connecting plate 22, and multiple springs 27. The mounting shaft extends front to back, and its front and rear ends are respectively fixed to the top of the transformer 1 by two fixing seats 24. The bottom ends of the two support arms 26 are respectively hinged to the front and rear ends of the mounting shaft, and the top ends of the two support arms 26 press against the bottom of the buffer frame 25. The bottom of the buffer frame 25 has sliding grooves extending in the left and right direction at the corresponding top ends of the four support arms 26. The top ends of the support arms 26 are embedded in the corresponding sliding grooves and can slide left and right along the sliding grooves. The two support arms 26 are connected across each other by the connecting plate 22. Multiple springs 27 are arranged at the bottom of the connecting plate 22, and the lower ends of the multiple elastic springs press against the top of the transformer 1.

[0026] The protective mechanism 3 includes a protective canopy 31 with an arched top and at least two support rods 32 at the bottom. The buffer frame 25 has at least two sleeves 33 at the top. Each support rod 32 is movably inserted into each sleeve 33. In this embodiment, the protective canopy 31 has four support rods 32 at the bottom, which are fixedly connected together by a cross-shaped frame 35. The cross-shaped frame 35 can stabilize the four support rods 32. The initial positioning and installation of the protective canopy 31 is achieved by inserting the four support rods 32 into the four sleeves 33.

[0027] The protective canopy 31 and the buffer frame 25 are locked together using a locking structure. The locking structure includes two locking rods 34 on the left and right sides of the buffer frame 25. The bottom of the protective canopy 31 has two horizontal beams, each with a through hole. The tops of the two locking rods 34 are threaded screws. These screws pass upwards through the through holes in the two horizontal beams and are then tightened with nuts 36, thus locking the protective canopy 31 to the buffer frame 25 and ensuring stable installation of the protective canopy 31 on the buffer frame 25, preventing it from wobbling. This structure facilitates the installation and removal of the protective canopy 31. If the protective canopy 31 is damaged by external forces, it can be easily replaced. Replacement is simple: loosen the nuts 36 on the two locking rods 34, remove the protective canopy 31 upwards, and then install the new protective canopy 31. The replacement operation is convenient and quick.

[0028] When a heavy object falls onto transformer 1, it will first come into contact with the surface of the protective canopy 31. Under the pressure exerted by the heavy object, the protective canopy 31 will transfer the pressure to the buffer frame 25, and the support arms 26 of the two sets of elastic support components will rotate slightly in opposite directions. At the same time, each spring 27 will be compressed. Under the action of the elastic force of the spring 27, the pressure exerted by the heavy object can be effectively weakened, thereby buffering the heavy object and protecting transformer 1.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
