Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the present utility model, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

Please refer to FIG. 1 , the buried transformer includes a rectangular cube pit 10 with the upper part exposed to the ground and an upper end open, a transformer installed in the pit 10 and an aboveground part located at the upper end of the pit 10 . The above-ground part includes ventilation windows and covers. Ventilation window comprises the form 2 that is installed on the outer side of the wall of the upper end face of pit 10, and this form 2 is surrounded by front and rear side frame 21,22 and left and right side frame 23,24; 2 adopt plastic-wood material to make; Cover plate comprises the left flip cover 31 of left end hinged on the upper end of left side frame 23 and the right flip cover 32 of right end hinged on the upper end of right side frame 24.

Please refer to Fig. 2 again, the cover plate supporting mechanism of the buried transformer of the present invention includes two transverse braces 51 and a longitudinal brace 52, wherein the two transverse braces 51 are spaced apart through connectors 50 Connected between the upper inner side of the left side frame 23 and the upper inner side of the right side frame 24, the transverse brace 51 is made of plastic-wood material; Between the center of the upper inner surface of the upper part and the center of the upper inner surface of the rear side frame 22; the connecting piece 50 includes a grooved part 501 and two mounting pieces 502 respectively connected to the rear ends of both sides of the grooved part 501; Three mounting holes are respectively provided on the sheet 502 (see FIG. 3 ); the longitudinal brace 52 and the connecting piece 50 are both made of stainless steel.
