Description

Technical Field

[0001] The utility model relates to the field of solar photovoltaics, in particular to a short guide rail photovoltaic panel mounting bracket. 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). Figure 14 After the guide rails are installed, the solar panels are then installed, and the panels are held in place by the middle edge of the guide rails. The entire installation process requires installing the rails one by one, which is cumbersome, time-consuming, and inefficient. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the utility model provides a short guide rail photovoltaic panel mounting bracket with a simple structure, easy installation, firm installation, saving the installation of long guide rails and reducing 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, including a short rail and a base, the base including a connecting part matched with the short rail and fixing parts on both sides, and a plurality of connecting holes are respectively provided on the fixing parts on both sides, which are fixed to the roof by a plurality of self-tapping screws. The short rail includes a mounting groove and a rectangular frame, the upper part of the mounting groove is an open groove, the mounting groove is matched and connected with the middle clamp for mounting the photovoltaic panel, the rectangular frame is matched and sleeved with the connecting part, a screw adjustment structure is provided between the rectangular frame and the connecting part, and a butyl rubber layer and release paper are provided at the bottom of the base.

[0005] As a preference, the screw adjustment structure includes an upper nut, a bolt and a lower nut, and threaded adjustment holes matching the bolts are respectively provided on the short track 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, the outer side of the short guide rail photovoltaic panel mounting bracket is also provided with an end cover.

[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 photovoltaic panels using a short guide rail photovoltaic panel mounting bracket,

[0012] First, arrange the short guide 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 guide rail photovoltaic panel mounting bracket to the roof with self-tapping screws;

[0013] Second, adjust the height of the short guide rail photovoltaic panel mounting bracket 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 fixture into the installation slot first, then install the middle fixture into the installation slot, and rotate the middle fixture 90 degrees before securing it;

[0015] Fourth, clamp each photovoltaic panel in the middle fixture and install it securely.

[0016] As a further improvement, when using a screw adjustment structure for adjustment, since a fixed rubber layer is provided on the upper and lower nuts of the screw where the upper nut and the bolt are fixed, the position will be tightened after being fixed and will serve as an upper and lower limit.

[0017] Once the position is fixed, it will be tightened and serve as an upper and lower limit.

[0018] The fixed adhesive layer of this utility model uses Loctite 204 threadlocker, a touch-dry, pre-applied adhesive used to lock and seal threaded fasteners. It remains inert on the fastener until the thread assembly releases a fast-curing resin. This resin fills all voids in the threads and, upon curing, locks and seals the assembly.

[0019] The beneficial effects of the present invention are as follows: the intermediate clamp used for photovoltaic panel installation is fixed by connecting to the short rail, which saves the installation of long guide rails and reduces costs. 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 connection 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 will 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 its use and ensure the flatness of the appearance.
