For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Referring to Figures 1 - 4 , according to an embodiment of a transformer with a guardrail of the present utility model, it includes a transformer body 11. A support plate 12 is hinged to each of the four vertical sides of the transformer body 11. The support plate 12 is located below the heat dissipation plate 91 inside the transformer body 11. A film winding assembly 101 is provided inside one of the support plates 12;

[0031] The winding film assembly 101 includes an empty groove 13 provided in the end face of the support plate 12. A rotating shaft 14 is rotatably connected in the empty groove 13, and a runner 15 is connected to the outside of the rotating shaft 14 through a clockwork spring. A blocking film 16 is wound around the outside of the runner 15. A locking assembly for clamping the blocking film 16 is further provided on the support plate 12 provided with the empty groove 13. In addition, the support plate 12 includes a positioning mechanism for controlling the angle of the support plate 12.

[0032] When the staff needs to set up the guardrail, the staff first fixes the angles of the four support plates 12 through the positioning mechanism. Then the staff pulls out the blocking film 16 and winds it around the ends of the respective support plates 12. Then the blocking film 16 is fixed through the locking assembly. At this time, the blocking film 16 winds around the transformer body 11 for one week and forms a fence, and the staff can control the size of the fence formed by the blocking film 16 by adjusting the angle of the support plate 12.

[0033] In this embodiment, the locking assembly includes a bottom plate provided on the lower side of the support plate 12. A support rod 17 is provided on the bottom plate. The locking assembly further includes a sleeve 18 provided at the end of the blocking film 16. The inner diameter of the sleeve 18 is not less than the diameter of the support rod 17, that is, the sleeve 18 can be sleeved outside the support rod 17 so that the end of the blocking film 16 after winding around for one week can be fixed. And the sleeve 18 is made of metal and has a relatively heavy weight to prevent it from slipping out of the support rod 17 under the influence of air flow.

[0034] Mounting plates 20 are provided on the four vertical side faces of the transformer body 11. There are two groups of mounting plates 20 distributed up and down, and a mounting shaft is rotatably connected between the upper and lower mounting plates 20. The four support plates 12 are respectively fixed on the four mounting shafts to complete the hinged installation of the support plates 12. The positioning mechanism includes a plurality of through holes provided in the upper mounting plate 20. The through holes are equiangularly arranged around the rotation axis of the mounting shaft installed in the mounting plate 20. A pin 22 inserted into the inner hole of the support plate 12 is further provided in the through hole. The staff can insert the pin 22 into the corresponding through hole and the pin hole after adjusting the angle of the support plate 12 to realize the angle locking of the support plate 12.

[0035] Under the action of the above-mentioned positioning mechanism, although the position of the support plate 12 can be locked, its wind resistance is poor, and the support plate 12 is prone to breakage at the pin holes. Therefore, in the second embodiment of the positioning mechanism, a reinforcing plate 23 is also hinged on the side of the support plate 12 close to the transformer body 11. One end of the reinforcing plate 23 away from the connected support plate 12 is also hinged with a locking plate 24. A plurality of bolt holes are provided in the vertical side of the transformer body 11, and the locking plate 24 is connected to the bolt holes by bolts to realize the support and reinforcement of the support plate 12.

[0036] In order to reduce the friction of the barrier film 16 during the process of winding it by the staff, rollers 19 are installed at the ends of the three support plates 12 without the empty slots 13 through brackets. The rollers 19 are used to conduct the barrier film 16 to prevent the staff from damaging the barrier film 16 when winding the barrier film 16 around each support plate 16.

[0037] In addition, the up and down position of the barrier film 16 is restricted by the mounting plate 20 to prevent it from falling off. To further prevent the barrier film 16 from falling off, multiple adhesive strips are arranged up and down on the inner side of the barrier film 16, and a rubber layer is arranged on the outer curved surface of the roller 19 to increase friction. And a warning message of "Keep Away" is printed on the outer side of the barrier film 16.

[0038] In order to reduce the influence of the barrier film 16 on the heat dissipation effect of the transformer body 11, a plurality of ventilation holes are provided in the barrier film 16.

[0039] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
