Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-3, a photovoltaic solar panel 1 double drainage tank includes a solar panel 1, a first drainage tank 2, and a second drainage tank 3. The first drainage groove 2 comprises a drainage groove 21 positioned in the gap between two adjacent solar panels 1 and pressing plates 22 respectively abutted against the upper surfaces of the two adjacent solar panels 1 at the tops of two sides of the drainage groove 21. The second water draining groove 3 is located below the solar panels 1, and two sides are provided with top plates 31 respectively propped against the bottoms of the two adjacent solar panels 1. In order to enhance the sealing performance, the sealing gasket 8 is arranged at the bottom of the pressing plate 22 and the top of the top plate 31, and the sealing gasket 8 can be made of rubber materials. When raining, most of the rainwater is discharged through the drain 21, and when a small amount of rainwater permeates below, the second drain 3 receives the rainwater. Double drainage is realized, and the occurrence of water leakage is greatly reduced.

The first water draining groove 2 and the second water draining groove 3 are connected through a plurality of bolts 4 which are arranged at intervals along the axial direction of the water draining groove 21, the bolts 4 are rotatably arranged at the bottom of the water draining groove 21, and the distance between the pressing plate 22 and the top plate 31 is shortened through rotating the bolts 4 to clamp the solar panel 1. The rotational mounting of the bolt 4 may be: a plurality of through holes 7 are formed at the bottom of the row ditch 21 and are arranged at intervals along the axial direction of the row ditch 21, and the bolts 4 can rotate after being inserted into the through holes 7, but the bolts 4 and the through holes 7 do not adopt threaded fit. A connecting block 5 is arranged at the bottom in the second water draining groove 3, and a plurality of threaded holes 6 which correspond to a plurality of bolts 4 up and down are formed in the top of the connecting block 5. During installation, the row ditch 21 is placed in a gap between two adjacent solar panels 1, two side pressing plates 22 respectively prop against the two solar panels 1, the notch of the second drainage groove 3 is upwards installed below the solar panels 1, and the threaded holes 6 on the connecting blocks 5 correspond to the through holes 7. At this time, the bolts 4 are inserted into the through holes 7 at the bottom of the drain grooves 21, and then the bolts 4 are screwed into the screw holes 6, so that the distance between the pressing plate 22 and the top plate 31 is reduced to clamp the solar panel 1 until the top plates 31 at the two sides of the second drain groove 3 are abutted against the bottom of the solar panel 1.
