The preferred embodiments of the application are shown in the drawings. However, the application can be realized in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] Referring to Figures 1-2 , the embodiment of the application provides a photovoltaic waterproof integrated roof assembly 30, which comprises a first photovoltaic panel assembly 10 and a second photovoltaic panel assembly 20.

[0032] Referring to Figures 3 to 5 , the first photovoltaic panel assembly 10 comprises a first photovoltaic panel 11, a first sealing strip 12 arranged at the bottom edge of the first photovoltaic panel 11, and a first fixing strip 13 arranged away from the first sealing strip 12, wherein the surface of the first fixing strip 13 away from the first sealing strip 12 has a first fixing structure 130.

The second fixing structure 230 is used for sealing connection with the first fixing structure 130, so that the first photovoltaic panel assembly 10 and the second photovoltaic panel assembly 20 form a stepped connection structure that facilitates drainage.

[0034] Compared with the prior art, the present application provides a photovoltaic waterproof integrated roofing component 30. The first sealing strip 12 and the first fixing strip 13 achieve waterproofing at the bottom of the first photovoltaic panel component 10, while the second sealing strip 22 and the second fixing strip 23 achieve waterproofing on the sides of the second photovoltaic panel component 20.

The protrusion 233 is fixed in the fixing groove 134 so that the first fixing structure 130 and the second fixing structure 230 are sealed together.

The integrated photovoltaic waterproof roofing assembly 30 may also include a plurality of third self-locking screws, which can sequentially pass through the first extension plate 132 and the protruding strip 233 and be fixed in the second extension plate 133. Through the first self-locking screws 41, the first fixing strip 13 and the first sealing strip 12 can be firmly locked to the bottom surface of the first photovoltaic panel 11, improving the sealing performance. The second self-locking screw 42 securely fastens the second fixing strip 23 and the second sealing strip 22 to the side of the second photovoltaic panel 21, improving the sealing performance. The third self-locking screw reliably connects the first fixing structure 130 of the first photovoltaic panel assembly 10 and the second fixing structure 230 of the second photovoltaic panel assembly 20, achieving a better sealing and waterproofing effect.

A third sealing strip 50 is provided between two adjacent first photovoltaic panel assemblies 10 and / or two adjacent second photovoltaic panel assemblies 20. The third sealing strip 50 includes an arc-shaped portion 51, a first bonding portion 52 connected to the inner side of the arc-shaped portion 51, and a second bonding portion 53 connected to the inner side of the arc-shaped portion 51 and spaced apart from the first bonding portion 52. The arc-shaped portion 51 includes a first bonding portion 52 connected to the inner side of the first bonding portion 51.

The third sealing strip 50 can achieve a sealed connection between two adjacent first photovoltaic panels 11 or two adjacent second photovoltaic panels 21, thus achieving the technical effect of waterproofing between two adjacent first photovoltaic panel assemblies 10 and between two adjacent second photovoltaic panel assemblies 20. Moreover, the third sealing strip 50 also has the technical effect of simple structure and convenient assembly.

[0042] The first connecting portion 512 and the first fitting portion 52 form a first acute angle, and the second connecting portion 513 and the second fitting portion 53 form a second acute angle. The first acute angle and the second acute angle are equal. The inner surface of the arc-shaped portion 51 is perpendicularly connected to both the first fitting portion 52 and the second fitting portion 53.
