[0022] 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 described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, a protective device for an external transformer heat sink comprises a main protective plate 1, and side protective plates 2 are connected to the left and right side axes of the main protective plate 1. An electric heating plate 13 is arranged directly below the main protective plate 1, and a limiting mechanism 5 is arranged directly above the main protective plate 1. The limiting mechanism 5 adjusts the angle of the side protective plate 2 to meet the requirements of unfolding the side protective plate 2 and adjusting the protection angle. A supporting mechanism 11 is arranged directly below the main protective plate 1, and the supporting mechanism 11 adjusts the shielding height according to the use requirements and supports the bottom end of the main protective plate 1.

[0024] In this embodiment, the limiting mechanism 5 includes a side protective plate 2, an arc rod 3, a fastening hole 4, a arc panel 6 and a plate fan 15. The arc rods 3 are symmetrically connected to the two sides of the side protective plate 2, and the fastening holes 4 are evenly spaced on the outer side of the arc rods 3. One side of the arc rod 3 is bolted to one side of the arc panel 6, and a plate fan 15 is arranged below the arc panel 6.

[0025] In this embodiment, the arc rod 3 is connected to both sides of the side guard plate 2 through fastening holes 4 evenly spaced on the outside, and the side guard plates 2 arranged on both sides are limited by the arc rod 3, and the side guard plates 2 are used to be unfolded and adjusted.

[0026] In this embodiment, the support mechanism 11 includes a guide slider 7, a support arm 1 8, a support arm 2 9, a fastener 10 and a transverse guide rod 14. The top of the support arm 1 8 is connected to the guide slider 7, the inside of the support arm 1 8 is penetrated by the support arm 2 9, one side of the support arm 2 9 is penetrated by the fastener 10, the outer side of the guide slider 7 is connected to the transverse guide rod 14, and the transverse guide rod 14 is symmetrically connected to the bottom end of the main protective plate 1. The support arm 1 8 is distributed in a rectangular shape below the main protective plate 1. The top of the transformer is shielded by the support arm 1 8 and the support arm 2 9 to meet the positioning and disassembly requirements of transformers of different shapes.

[0027] In this embodiment, the main protective plate 1 is connected to the input end of the electric heating plate 13 through a power supply line 12 running through the bottom end. The main protective plate 1 is used to shield the top of the transformer to prevent hard objects from directly hitting the top of the transformer.

[0028] In this embodiment, drainage grooves 16 are symmetrically provided on both sides of the side protection plate 2, and the drainage grooves 16 are used to allow the melted liquid to flow out directly, thereby completing the melting of ice and snow.

[0029] In this embodiment, the support arm 8 is connected to the outer side of the transverse guide rod 14 via a guide slider 7 connected to the top end. The support arm 8 is vertically slid using the guide slider 7 to indirectly adjust the two groups of support arms 8.

[0030] The practical application of this external transformer heat sink protection device includes the following work contents:

[0031] Step 1: The operator can pull the support arm 8 according to the width of the transformer. The support arm 8 slides on the outside of the transverse guide rod 14 through the guide slider 7 set at the top, and the indirect adjustment of the two groups of support arms 8 is performed. The operator locks the connection between the support arm 8 and the transverse guide rod 14 through bolts, and the top of the heat sink can be replaced by the plate fan 15 to meet the surface attachment heat dissipation of the heat sink;

[0032] Step 2: First, according to the size of the transformer, the operator can pull the support arm 2 9 provided below so that the support arm 2 9 slides vertically on the outside of the support arm 1 8, and adjust the connection between the support arm 1 8 and the support arm 2 9, and lock the support arm 1 8 and the support arm 2 9 by bolts, or adjust the height of the two groups of the support arm 2 9 to a shorter part, so as to meet the top shielding treatment of different types of transformers, and lock the two sides of the transformer by fasteners 10 to complete the top shielding protection of the transformer;

[0033] Step 3: During use, when it is necessary to shield the protruding part of the transformer, the operator positions the arc panel 6 and one side of the arc rod 3, and inserts the bolts into the fastening holes 4 to lock the connection between the arc panel 6 and the arc rod 3 to shield and protect the protruding part;

[0034] Step 4: When the operator performs shielding in winter, the operator holds the side protective plate 2, and the side protective plate 2 is rotated on both sides of the main protective plate 1 through the axis set on the outside, and the angle of the side protective plate 2 is adjusted. The side protective plate 2 and the two sides of the arc rod 3 are locked through the fastening hole 4 to prevent the side protective plate 2 from displacement, and the bottom end of the main protective plate 1 is heated by the electric heating plate 13 to avoid extrusion damage caused by ice and snow accumulation. The melted ice water directly flows to both sides of the transformer through the drain groove 16.

[0035] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
