The present application claims priority to Chinese Patent Application No. 201721265816.2 and filed with the Chinese Patent Office on Sep. 28, 2017, the content of which is hereby incorporated by reference in its entirety.
The disclosure relates to the mounting technique of the photovoltaic module, and particularly to a back-hang mounting assembly of a thin film photovoltaic module.
The solar energy is a kind of clean energy, of which the exploitation and utilization are valued by various countries in the world. How to efficiently collect and utilize the solar energy is fairly far-reaching for the environmental protection. The thin film is the future of the photovoltaic power generation, particularly along with the further improvement of the module efficiency, and the flexibility and thin film tendency will become the emerging development direction of the photovoltaic market gradually. But the thin film modules are mostly the frameless double-glazed modules, where the thin film modules have the higher installation breakage rate due to their special double-glazed structure and the improper operations in the installation.
The fixation of the thin film photovoltaic module in the related art needs to use the clamp to impact and fix in the front plate direction of the module, which often causes the breakage phenomenon of the pressed module glass due to the overexertion. Meanwhile there are the problems of blocking the light rays and affecting the electric energy production, and the installation operations are inconvenience and the construction progress is slow.
The disclosure provides a back-hang mounting assembly of a thin film photovoltaic module, which includes: a back-hang hook plate of which a cross section is F-shaped and which is fixedly connected to the photovoltaic module, a cross beam configured to be fixedly connected to a roof and fixed to the back-hang hook plate by hook joint.
In order to make the objects, technical solutions and advantages of the disclosure clearer, the technical solutions of the embodiments of the disclosure will be described clearly and completely below in combination with the accompanying drawings of the embodiments of the disclosure. Obviously the described embodiments are a part of the embodiments of the disclosure but not all the embodiments. Based upon the embodiments of the disclosure, all of other embodiments obtained by those ordinary skilled in the art without creative work pertain to the protection scope of the disclosure.
The embodiments of the disclosure will be described below in details and the examples of these embodiments are shown in the drawings, in which the same or similar reference numbers represent the same or similar elements or the elements having the same or similar functions all the way. The embodiments described by reference to the drawings are exemplary and only used to explain the disclosure, but not interpreted as the limitations of the disclosure.
As shown in
The back-hang mounting assembly of the thin film photovoltaic module according to the embodiment of the disclosure includes the back-hang hook plate 2 of which the cross section is similar to the F shape, where one end thereof is fixedly connected to the photovoltaic module, and the other end is fixed to the cross beam 4 by the hook joint and then connected to the roof by the cross beam 4, to thereby implement the installation of the photovoltaic module on the roof. Compared with the related art, the damage to the glass is avoided, and furthermore the structure is simple and the installation is relatively convenient.
In some embodiments, as shown in
The back-hang hook plate 2 of the mounting assembly is fixedly connected to the glass back plate 1 of the photovoltaic module.
In some embodiments, the back-hang hook plate 2 includes a horizontal plate 21, a first L-shaped plate 22 and a second L-shaped plate 23. The horizontal plate 21 is fixedly connected to the glass back plate 1, the first end of the first L-shaped plate 22 and the first end of the second L-shaped plate 23 are both fixed on the horizontal plate 21, and the second end of the first L-shaped plate 22 and the second end of the second L-shaped plate 23 both form the hook shapes bending towards the same direction and having different heights. The back-hang hook plate 2 forms the structure of which the cross section is similar to the F shape.
The cross beam 4 includes a base plate 41, a third L-shaped plate 42 and a fourth L-shaped plate 43. The base plate 41 is configured to be fixedly connected to the roof, the first end of the third L-shaped plate 42 and the first end of the fourth L-shaped plate 43 are both fixed on the base plate 41, the second end of the third L-shaped plate 42 and the second end of the fourth L-shaped plate 43 both form the hook shapes bending towards the same direction and having different heights, the third L-shaped plate 42 is hooked to the first L-shaped plate 22, and the fourth L-shaped plate 43 is hooked to the second L-shaped plate 23. The cross beam 4 forms the structure of which the cross section is similar to the F shape.
The back-hang mounting assembly of the thin film photovoltaic module according to the embodiment of the disclosure includes the back-hang hook plate 2 of which the cross section is similar to the F shape, where one end thereof is fixedly connected to the glass back plate 1 of the photovoltaic module, and the other end is fixed to the cross beam 4 by the hook joint and then connected to the roof by the cross beam 4, to thereby implement the installation of the photovoltaic module on the roof. Compared with the related art, the damage to the glass is avoided, and furthermore the structure is simple and the installation is relatively convenient.
In some embodiments, the back-hang hook plate 2 is fixedly connected to the glass back plate 1 via the structural adhesive 3. It can be understood that the back-hang hook plate 2 may also be fixedly connected to the glass back plate 1 by the rivet joint, screw joint or others.
In some embodiments, the mounting assembly further includes a limit bolt 5, which passes through the first L-shaped plate 22 and then presses against the third L-shaped plate 42; and/or, which passes through the fourth L-shaped plate 43 and then presses against the second L-shaped plate 23, to thereby limit the relative motion of the back-hang hook plate 2 and the cross beam 4.
In some embodiments, the mounting assembly further includes a first fixing bolt 6. The first fixing bolt 6 passes through the base plate 41 and is then fixedly connected to the first L-shaped plate 22 and/or second L-shaped plate 23.
In some embodiments, the mounting assembly further includes an oblique beam 8. The base plate 41 of the cross beam 4 is fixed on the oblique beam 8, and the oblique beam 8 is configured to be fixedly connected to the roof. The mounting assembly may further include a second fixing bolt 7. The second fixing bolt 7 passes through the base plate 41 and is then fixedly connected to the oblique beam 8. The stable connections between the cross beam 4 and the back-hang hook plate 2 and between the cross beam 4 and the oblique beam 8 are achieved by arranging the first fixing bolt 6 and the second fixing bolt 7.
As shown in
The number of the back-hang hook plates 2 can be set according to the size of the photovoltaic module. In some embodiments, there are two back-hang hook plates 2 and two back-hang hook plates 2 are perpendicular or parallel to each other to increase the installation strength of the photovoltaic module. The material of the back-hang hook plate 2 may be the aluminium alloy, to thereby implement the lightweighting of the mounting structure.
The back-hang mounting assembly of the thin film photovoltaic module according to the disclosure includes the back-hang hook plate of which the cross section is similar to the F shape, where one end thereof is fixedly connected to the photovoltaic module, and the other end is fixed to the cross beam by the hook joint and then connected to the roof by the cross beam, to thereby implement the installation of the photovoltaic module on the roof.
