Description

Technical Field

[0001] The invention relates to the field of solar photovoltaics, and in particular to a short guide rail photovoltaic panel mounting bracket and a mounting method thereof. Background Art

[0002] At present, the photovoltaic panel assembly installed on the roof mainly includes photovoltaic panels and photovoltaic brackets, and the photovoltaic panels are installed on the roof through the photovoltaic brackets. The existing structure first fixes the guide rail base on the roof, and then installs the guide rails through the guide rail base. The guide rails need to be installed one by one, and the guide rails are connected by a connecting key in the middle of the guide rail base (as shown in the attached figure). Fig.14 As shown). After the guide rails are installed, the solar photovoltaic panels are installed. The solar photovoltaic panels are fixed by the middle edge of the guide rails. The entire installation process needs to be installed one by one because of the installation of the guide rails. The operation is cumbersome, the installation time is long, and the overall work efficiency is too low. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a short guide rail photovoltaic panel mounting bracket and an installation method thereof, which has a simple structure, is easy to install, is firmly installed, saves the installation of long guide rails, and reduces costs.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a short guide rail photovoltaic panel mounting bracket, which is installed and fixed to the roof, comprises a short rail and a base, wherein the base comprises a connecting portion matched with the short rail and fixing portions on both sides, and a plurality of connecting holes are respectively provided on the fixing portions on both sides; the short rail comprises a mounting groove and a rectangular frame, the upper portion of the mounting groove is an open groove, the mounting groove is matched with the middle clamp for mounting the photovoltaic panel, the rectangular frame is matched with the connecting portion, a screw adjustment structure is provided between the rectangular frame and the connecting portion, and a butyl rubber layer and release paper are provided at the bottom of the base.

[0005] Preferably, the screw rod adjustment structure comprises an upper nut, a bolt and a lower nut, and threaded adjustment holes matching the bolts are respectively provided on the short rail and the connecting portion.

[0006] As a further improvement, a fixing rubber layer is provided on the screw rod and inside the lower nut at the location where the upper nut is fixed to the bolt.

[0007] As a further improvement, the rectangular frame includes side panels on both sides and limiting strips at the front and rear of the bottom.

[0008] As a further improvement, an end cover is also provided on the outer side of the short guide rail photovoltaic panel mounting bracket.

[0009] As a preference, the butyl rubber layer comprises two layers.

[0010] As a further improvement, an EPDM gasket is provided between the bottom of the base and the butyl rubber layer.

[0011] A method for installing a photovoltaic panel using a short guide rail photovoltaic panel mounting bracket,

[0012] First, arrange the short rail photovoltaic panel mounting bracket according to the required position, remove the release paper, adhere the butyl adhesive layer to the arranged position, and then fasten the short rail photovoltaic panel mounting bracket to the roof with self-tapping screws;

[0013] Second, the height of the short guide rail photovoltaic panel mounting bracket is adjusted through the screw adjustment structure so that the height of each short guide rail photovoltaic panel mounting bracket is at the same horizontal plane;

[0014] Third, install the hidden end clamp into the installation slot first, then install the middle clamp into the installation slot, and rotate the middle clamp 90 degrees before fixing it;

[0015] Fourth, each photovoltaic panel is clamped in the middle fixture and fixed.

[0016] As a further improvement, when a screw adjustment structure is used for adjustment, since a fixed rubber layer is provided on the screw and inside the lower nut where the upper nut and the bolt are fixed, the position will be tightened after being fixed and play a role in upper and lower limit.

[0017] After the position is fixed, it will be tightened and play the role of upper and lower limit.

[0018] The fixing adhesive layer of the present invention uses Loctite 204 threadlocker, which is a touch-dry pre-applied adhesive used for locking and sealing threaded fasteners. It will remain inert on the fastener until the thread assembly releases a fast-curing resin. This resin will fill all the gaps in the thread and lock and seal the assembly after curing.

[0019] The beneficial effects of the present invention are as follows: the intermediate clamp used for installing the photovoltaic panel is connected and fixed with the short rail, which saves the installation of the long guide rail and reduces the cost. The overall structure is simple, the volume is small, and the installation is convenient. A screw adjustment structure is provided between the short rail and the connecting part, which can adapt to slightly uneven roofs. After adjustment, the height of each short guide rail photovoltaic panel mounting bracket is in the same horizontal plane, and the installation effect is good. The nut and the lower nut of the upper screw adjustment structure are both provided with a fixed glue layer, which can be tightened after the position is fixed, and play the role of upper and lower limit. The limit strip provided at the bottom of the rectangular frame can limit the front and rear position during installation, and the side panels on both sides limit the left and right positions, both of which play the role of maintaining balance. The outer side of the short guide rail photovoltaic panel mounting bracket is also provided with an end cover to protect it and ensure the flatness of the appearance.
