[0023] Specifically, the fixing fixture 101 of each group of the protective frames 10 respectively includes a fixing frame 1011, an outer retaining arm 1012, an inner retaining arm 1013 and a clamping bolt 1014. The fixing frame 1011 is horizontally arranged, and the grid frame 102 is vertically arranged at the upper end of the fixing frame 1011. The outer retaining arm 1012 and the inner retaining arm 1013 are respectively welded to the lower end of the fixing frame 1011 at intervals along the length direction of the fixing frame 1011, and the distance between the outer retaining arm 1012 and the inner retaining arm 1013 is greater than the thickness of the parapet wall. The clamping bolt 1014 is horizontally arranged through the inner retaining arm 1013 and is in threaded fit connection with the inner retaining arm 1013. The shaft end of the clamping bolt 1014 passing through the inner retaining arm 1013 is opposite to the outer retaining arm 1012. A clamping channel for clamping the parapet wall is formed between the outer retaining arm 1012 and the clamping bolt 1014. By rotating the clamping bolt 1014, the clamping bolt 1014 can move towards the outer retaining arm 1012 in an opposing manner. When installing the protective frame 10, the fixing frame 1011 is spanned across the upper end of the parapet wall on the substation roof, so that the outer retaining arm 1012 on the fixing frame 1011 is vertically blocked outside the parapet wall, and the inner retaining arm 1013 is vertically blocked inside the parapet wall, and the grid frame 102 arranged at the upper end of the fixing frame 1011 is kept in a vertical state. By manually rotating the clamping bolt 1014, it moves towards the outer retaining arm 1012 in an opposing manner and abuts against the inner wall of the parapet wall. By continuously rotating the clamping bolt 1014, a mutual clamping force is formed with the outer retaining arm 1012, and they are mutually clamped on the inner and outer sides of the parapet wall to fix the fixing frame 1011. Through this clamping and fixing method, at least two groups of the protective frames 10 are clamped and fixed at intervals along the length direction of the parapet wall.
