[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-7 The utility model provides a technical solution: a protective device for transformer maintenance, comprising a mounting platform 1 and a transformer 2 arranged on the mounting platform 1, side guardrails 3 are fixedly installed on both sides of the mounting platform 1, and an adjustment component 4 for adjusting the working space of maintenance personnel is arranged on the mounting platform 1.

[0028] Specifically, Figure 1 As shown, the adjustment component 4 includes a main guardrail 401 hinged on the front and back of the installation platform 1 (a connecting pin is provided between the main guardrail 401 and the side guardrail 3 for fixing the main guardrail 401, which is not shown in the figure), and a slide groove 402 is provided on the upper surface of the installation platform 1 and the inner side of the main guardrail 401. A slider 403 is slidably connected in the slide groove 402 on the installation platform 1, and a protective cover plate 404 is hinged on the upper end of the slider 403. The main guardrail 401 is hinged on the installation platform 1. During maintenance, the main guardrail 401 can be laid flat to increase the maintenance space. A new guardrail is formed by folding the protective cover plate 404, erecting it, and sliding it along the slide groove 402 to the end of the flattened main guardrail 401.

[0029] Further, such as Figure 4As shown, the slider 403 and the protective cover 404, and the installation platform 1 and the main guardrail 401 are hinged by hinges, and the hinges are arranged on the side close to the transformer 2. The hinges are arranged on the side close to the transformer 2, which is convenient for limiting the main guardrail 401 after it is laid flat and the protective cover 404 is erected. The lower side of the main guardrail 401 abuts against the lower side of the installation platform 1 to prevent the main guardrail 401 from continuing to flip over. Similarly, the protective cover 404 can also be limited.

[0030] Further, such as Figure 2 , Figure 6 and Figure 7 As shown, the connecting ends of the mounting platform 1 and the main guardrail 401 are both provided with a plug-in slot 405, the inner wall of the plug-in slot 405 is inserted with a support rod 406, and the mounting platform 1 is provided with an adjustment slot 407 connected to the plug-in slot 405. One end of the support rod 406 located in the plug-in slot 405 on the mounting platform 1 is provided with a flat notch 408. By arranging the support rod 406 in the plug-in slot 405, during maintenance, a flat bolt driver is inserted into the adjustment slot 407 and stuck into the flat notch 408, thereby pushing the support rod 406 into the plug-in slot 405 on the flattened main guardrail 401 to support the main guardrail 401.

[0031] Among them, Figure 2 and Figure 4 As shown, a folding step ladder 5 is hinged on the surface of the protective cover plate 404, and connecting columns 6 are welded on both sides of the protective cover plate 404. A limiting steel cable 7 is bolted to the surface of the connecting column 6 on one side, and the other end of the limiting steel cable 7 is connected to another connecting column 6. The limiting steel cable 7 is used to limit the folding step ladder 5. When repairing, the folding step ladder 5 is unfolded to facilitate the transportation of repair tools and accessories.

[0032] like Figure 2 As shown, an inspection window is provided on the surface of the protective cover 404 , and an inspection door 9 is rotatably connected to the inner wall of the inspection window. A latch 10 is provided between the inspection door 9 and the protective cover 404 , and between the slider 403 and the protective cover 404 .

[0033] Further, such as Figure 1 As shown, a tool box 11 is fixedly installed on the side of the side guardrail 3, and cleaning tools are placed in the tool box 11. The cleaning tools in the tool box 11 are used to clean the dead branches, rotten leaves and animal feces on the installation platform 1.

[0034] Further, such as Figure 1 and Figure 5As shown, the side guardrail 3 is fixedly installed with an L-shaped rod 12, and the upper end of the L-shaped rod 12 is rotatably connected to an impeller 13, the material of the impeller 13 is stainless steel, and the side of the side guardrail 3 is fixedly connected to a knocking ball 8 through a spring. The wind force is used to drive the impeller 13 to rotate, thereby colliding with the knocking ball 8, and driving away birds with sound.

[0035] Working principle: During maintenance, the main guardrail 401 is laid flat and supported by the support rod 406 to expand the available space, and then the protective cover 404 is erected and pushed to the end of the main guardrail 401 to protect the flat main guardrail 401, thereby expanding the space for maintenance personnel to display their skills and providing protection for the maintenance personnel. After the maintenance personnel use tools to climb onto the installation platform 1, they use the cleaning tools in the tool box 11 to clean the installation platform 1 and the protective cover 404, and finally open the maintenance door 9, and put down the folding step ladder 5, and use the folding step ladder 5 to transport maintenance tools and accessories.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
