The solar photovoltaic panel is characterized in that a plurality of lower positioning screw holes communicated with the grooves are formed in the first flange, upper positioning screw holes communicated with the grooves and corresponding to the lower positioning screw holes one to one are formed in the upper side wall of the clamping frame, positioning screws are screwed in each lower positioning screw hole and each upper positioning screw hole, the end portions of the positioning screws extend into the grooves, and the solar photovoltaic panel is clamped among the end portions of the plurality of positioning studs.
And glue is filled in a gap between the inner wall of the groove and the outer wall of the outer edge of the solar photovoltaic panel.
The end part of the positioning screw is fixed with a nylon top block which is propped against the solar photovoltaic panel.
A plurality of linearly and uniformly distributed glue pouring holes communicated with the grooves are formed in the first flange, and upper glue pouring holes communicated with the grooves are formed in the upper side wall of the clamping frame.
The lower glue injection hole and the upper glue injection hole are waist-shaped holes.
And the stud is formed with a hexagonal hole with an opening at the upper side.
The invention has the following outstanding effects: compared with the prior art, it can carry out the auto-lock with the screw through the integral key shaft, can effectively prevent that it from producing not hard up drunkenness that causes the photovoltaic board, and it can be with photovoltaic board location, rubberizing simultaneously, increases the stability between photovoltaic board and the frame.
