Detailed Description

The utility model will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:

as shown in fig. 1 to 3, a solar photovoltaic backplate waterproof construction, including plate body 4, there is the chamber 1 of placing that supplies to place panel 31 in its upper surface indent, the chamber lateral wall of placing chamber 1 is located the equal indent of same level and has the appearance chamber 2 that supplies to place glass board 32 to make glass board 32 cover on panel 31, and it has water drainage tank 3 to be recessed along glass board 32 profile in appearance chamber 2 bottom surface, plate body 4 one side is seted up and is held opening 5 that chamber 2 and water drainage tank 3 are linked together, has seal groove 7 along glass board 32 edge profile indent in appearance chamber 2 top surface, be provided with in the seal groove 7 and supply the sealing member 6 of sealed conflict glass board 32. It is specific, place in placing the intracavity through the panel, and arrange in through the glass board and placing the intracavity that holds that the chamber wall formed, and then the glass board is the lid state that covers the panel, the rethread is holding the intracavity and is setting up the sealing member and contradict on the glass board, and then in order to realize the glass board along the sealed of edge profile, the rethread is recessed water drainage tank that sets up along glass board edge profile in holding the intracavity, and then avoid taking place the sealed poor condition that leads to the seepage of sealing member, thereby the water liquid of warp sealed piece seepage flows as for in water drainage tank by the glass board edge, discharge again by the plate body opening, thereby reach better sealed effect.

The bottom surface of the drainage channel 3 is inclined downwards from one end far away from the opening 5 to one end close to the opening 5. Specifically, the bottom surface of the drainage groove is obliquely arranged, so that when water liquid generated by leakage flows to the drainage groove, the water liquid directly flows out of the opening through the inclination of the inclined surface.

A plurality of bosses 8 are upwards protruded on the upper surface of the plate body 4 along the edge profile of the sealing groove 7 at intervals, screw holes 9 communicated with the sealing groove 7 penetrate through the upper ends of the bosses 8, and fastening pieces 10 for abutting against the sealing piece 6 are connected to the screw holes 9 in a threaded fit mode. Specifically, the sealing element is tightly pressed against the sealing element through the threads of the fastening element, so that the sealing joint between the sealing element and the glass plate can be kept for a long time.

The fastener 10 comprises a fastening screw 11 and a cover 12 integrally connected to the fastening screw 11 for covering the boss 8. Specifically, through block and boss cooperation to avoid the condition of producing the weeping by the screw hole when rainy day.

The height of the sealing groove 7 is greater than the thickness of the sealing member 6. And then so that the glass board is inserted and is located holding the intracavity by the opening, reduces the friction of sealing member when the glass board inserts and holds the chamber, and when the chamber was arranged in completely to the glass board, the rethread fastener supported the sealing member and sealed the laminating and realize sealed laminating on the glass board.

The sealing element 6 comprises a pressing plate 13 which is movably arranged in the sealing groove 7 up and down and a sealing strip 14 which is connected to one side of the pressing plate 13 and can be elastically deformed. Specifically, the pressing plate is tightly pressed through the fastening piece, and then the pressing plate presses the sealing strip to deform and abut against the glass plate, so that sealing is realized.

The plate body 4 is detachably connected with a cover plate 15 at one side of the opening 5, and a water outlet 16 communicated with the water drainage groove 3 is formed between the cover plate 15 and the plate body 4 in a clinging manner.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
