Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1 to 3, a lightning protection grounding device for a wind power plant includes a connecting frame 3, a lightning arrester 4 fixedly connected to a lower end of the connecting frame 3, a connecting wire 5 connected to a lower end of the lightning arrester 4, its characterized in that dismantles the change in order to make things convenient for 4 lightning arresters, one side of link 3 is provided with coupling mechanism, coupling mechanism includes mounting panel 2, one side fixed surface of link 3 is connected with connecting plate 11, spread groove 10 has been seted up on the surface of mounting panel 2, the one end sliding connection of spread groove 10 has clamp plate 9, connecting plate 11 inserts in the spread groove 10 and sticiss through clamp plate 9 and carry out spacing fixed on the connecting plate 11, knob bolt 1 has been closed through the screw thread soon in the upper end of mounting panel 2, mounting panel 2 is passed to knob bolt 1's one end and is connected with clamp plate 9, can drive clamp plate 9 and slide in spread groove 10 when rotating knob bolt 1.
Further, the shape of looking sideways at of connecting plate 11 is the dovetail, and sticiss board 9 sticiss the block on connecting plate 11 through mounting panel 2, makes connecting plate 11 install more stably in spread groove 10.
Furthermore, the four corners of the mounting plate 2 are provided with fixing screw holes, so that the mounting plate 2 is conveniently and fixedly mounted at the use position of the lightning arrester 4.
Further, the one end of connecting wire 5 is connected with branching ground frame 6, and the lower extreme of branching ground frame 6 is connected with ground ring 7, and ground ring 7's lower surface is provided with vertical ground pole 8, makes arrester 4 can better carry out lightning protection ground conduction through branching ground frame 6, ground ring 7 and vertical ground pole 8 when taking shelter from the thunder.
