Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic panels, and specifically relates to a lightweight bracket for fixing photovoltaic panels on a roof. Background Art

[0002] A photovoltaic panel is a common power generation device. Different-shaped fixing brackets are used during its installation, and the common fixing brackets are divided into single-piece fixing brackets and herringbone fixing brackets. However, the existing herringbone bracket structures are relatively complex and heavy, and the openings of the fixing bases on the fixing brackets cannot be adjusted when fixing the photovoltaic panels, resulting in poor adaptability of the support frame and inability to adapt to photovoltaic panels of different thicknesses. At the same time, no counterweight is added to the existing fixing brackets, making it relatively unsafe to use in windy areas. Summary of the Utility Model

[0003] In view of the defects existing in the existing herringbone photovoltaic panel roof fixing brackets, the technical problem to be solved by the utility model is to provide a lightweight bracket with a relatively simple structure and an adjustable opening size of the fixing base. At the same time, the lightweight bracket is also provided with a counterweight.

[0004] To achieve the above object, according to one aspect of the utility model, the utility model is realized by the following technical measures: A lightweight bracket for fixing photovoltaic panels on a roof, comprising: a bottom beam, there are two bottom beams, and they are arranged relatively parallel. A vertically arranged column is fixed on each bottom beam. At the same time, fixing bases are provided at both ends of the bottom beam and the upper ends of the columns. The fixing base is composed of a fixing seat, a chuck and a bolt. The fixing seat is a fixing member of the fixing base, and the top surface of the fixing seat is an inclined surface. The chuck is a vertical stepped block formed by alternating connection of two horizontal plates and two vertical plates, and the lower vertical plate can abut against the top surface of the fixing seat. The bolt passes through the lower horizontal plate and the fixing seat so that the upper horizontal plate of the chuck can cooperate with the fixing seat to lock the photovoltaic panel assembly.

[0005] Further, a column fixing seat is also provided on the two bottom beams. The lower end of the column is inserted into the column fixing seat and fixed by a bolt.

[0006] Further, both of the two bottom beams are hollow square tubes. A sliding opening is formed on the top surface of the bottom beam. The fixing seat on the bottom beam is fixed to the bottom beam by a bolt and a nut. The tail of the bolt is inside the bottom beam, and the screw of the bolt is stuck in the sliding opening and passes through the front fixing base and is fixed by a nut. The column is a telescopic column and can be locked after being stretched or retracted a certain distance.

[0007] Further, the bottom beam on both sides of the sliding opening is bent downward to form a resisting head.

[0008] Further, counterweights are also provided on both of the two bottom beams.

[0009] Further, there are four counterweight blocks, with two counterweight blocks provided on each bottom beam, and the two counterweight blocks on the same bottom beam are located at both ends of the vertical pole. The counterweight blocks are fixed by L-shaped fasteners.

[0010] Compared with the prior art, the advantages of the present utility model are as follows: 1. The overall structure is simple and reliable. At the same time, the fixed base can fix photovoltaic panel assemblies with a wide range of thicknesses; 2. The design of multiple counterweight blocks is added, making it safer to use.

These drawings are included to provide a further understanding of the present disclosure, and the drawings are included in this specification and form a part of this specification. In the drawings:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "over", "upper", and "side (e.g., as in "side wall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacturing. For example, if the device in the drawing is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "under" orientations. In addition, the device may be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0019] As Figures 1-4 shown, a lightweight bracket for fixing a photovoltaic panel roof according to the present utility model includes: a bottom beam 1, a column 2, a fixed base, and a counterweight 12. There are two bottom beams 1, which are arranged relatively parallel. A vertically arranged column 2 is fixed on each bottom beam 1. At the same time, fixed bases are provided at both ends of the bottom beam 1 and the upper end of the column 2. The two fixed bases have the same structure. For the convenience of description, the fixed base on the bottom beam 1 is the front-end fixed base 3, and the fixed base on the column 2 is the rear-end fixed base 4. The fixed base is composed of a fixed seat 5, a chuck 6, and a bolt 7. The fixed seat 5 is a fixing part of the fixed base for fixing with the bottom beam 1 and the column 2, and the top surface of the fixed seat 5 is an inclined surface 8. The chuck 6 is a vertical stepped block formed by alternately connecting two horizontal plates and two vertical plates, and the lower vertical plate can abut against the top surface of the fixed seat 5. The bolt 7 passes through the lower horizontal plate and the fixed seat 5 so that the upper horizontal plate of the chuck 6 can cooperate with the fixed seat 5 to lock the photovoltaic panel assembly.

[0020] For the convenience of fixing, a column fixing seat 9 is also fixed on the two bottom beams 1. The lower end of the column 2 is inserted into the column fixing seat 9 and fixed by bolts. At the same time, the two bottom beams 1 are both hollow square tubes. A sliding opening 10 is formed on the top surface of the bottom beam 1. The bottom beam 1 on both sides of the sliding opening 10 is bent downward to form a resisting head 11. The front-end fixed seat 3 and the bottom beam 1 are fixed by bolts and nuts. The tail of the bolt is inside the bottom beam 1 and abuts against the resisting head 11, and the screw of the bolt is stuck in the sliding opening 10 and passes through the front-end fixed base 3 and then is fixed by a nut. The column 2 is a telescopic column and can be locked after being stretched or retracted by a certain distance. The above design is convenient for tilting adjustment of the photovoltaic panel assembly. Of course, the adjustment can only be fine-tuned.

[0021] Preferably, the fixed base 4 of the front-end fixed base 3 is preferably a structure with square blocks plus fixing plates on both sides, and the fixed base 4 of the rear-end fixed base 4 is preferably a triangular block.

[0022] In order to ensure the safe use of the light support and prevent it from being blown down by strong winds, two counterweight blocks 12 are fixedly arranged on each of the two bottom beams 1. The two counterweight blocks 12 on the same bottom beam 1 are located at both ends of the vertical pole 2, and the counterweight blocks are fixed by L-shaped fasteners 13.
