The four bending parts are parallel to each other, and the bending directions all face to the same side, so that the longitudinal section of the bottom plate is C-shaped. For convenience of description, the side toward which the bend is directed is referred to as the inner side, and vice versa. The portion above the second bend is formed as the top of the base panel and the portion below the third bend is formed as the bottom of the base panel. The steel wire mesh covers the outer side surfaces of the upper half part and the top part of the bottom plate along with the shape, namely the steel wire mesh is also provided with bends corresponding to the first bend and the second bend. The top edge 121 of the wire mesh extends beyond the top edge of the base plate. When the rapid water guide device is used, the rapid water guide device needs to be buckled on the outer side of the lower edge of the frame of the photovoltaic assembly along with the shape, and when water is accumulated at the junction of the lower edge of the frame and the glass, the rapid water guide device can play a role in rapidly guiding water outwards. The quick water guide device is fastened at the outer side of the lower edge of the frame by means of elasticity, so that the quick water guide device is very easy to mount and has a stable structure.

The rapid water guide device is simple in structure, low in manufacturing cost and convenient to transport.
