Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to a lightweight photovoltaic component frame. Background Art

[0002] Photovoltaic brackets are structural frames used to support solar photovoltaic panels, usually made of metal materials such as aluminum alloy or galvanized steel. Its main function is to fix the solar photovoltaic panels at a suitable angle to maximize the absorption of sunlight and convert it into electrical energy; the frame of the photovoltaic bracket assembly usually refers to the frame structure installed around the solar photovoltaic panels. These frames are usually made of weather-resistant and corrosion-resistant materials such as aluminum alloy or stainless steel to ensure that the solar panels can maintain stable support and protection under various environmental conditions. The frame is designed to provide support and protection while minimizing the impact of shadows on the solar panels, thereby improving power generation efficiency.

[0003] The frame of the photovoltaic bracket assembly is used to fix the photovoltaic bracket assembly, especially in the tracking photovoltaic bracket assembly, which must be as lightweight as possible so that the rotating mechanism can drive the photovoltaic bracket assembly to adjust the angle to follow the direct sunlight. In order to reduce the weight, hollowing out the frame of the photovoltaic bracket assembly is generally adopted to reduce the weight without affecting the structural stability. However, after multiple hollowing out, in windy and sandy weather, external dust and sand can enter the frame of the photovoltaic bracket assembly through the hollow holes and cause wear and tear and hollow filling, resulting in weight increase and erosion, further increasing the maintenance cost. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] The technical problem to be solved by the utility model is that the current lightweight photovoltaic module battery panels use hollow frames to reduce weight, but after multiple hollowing out, in windy and sandy weather, external dust and sand can enter the photovoltaic bracket module frame through the hollow holes and cause wear and tear and hollow filling, resulting in weight increase and erosion, further increasing maintenance costs.

[0006] (II) Technical solution

[0007] In order to solve the above problems, the utility model provides the following technical solutions:

[0008] A lightweight photovoltaic module frame comprises a frame body, a connecting frame is provided on the outside of the frame body, a hollow groove is provided between the connecting frame and the frame body, a first connecting plate and a second connecting plate are provided at the bottom of the connecting frame, a frame connecting bolt is provided in the first connecting plate, a back plate connecting bolt is provided in the second connecting plate, a filling frame is provided in the hollow groove, the filling frame comprises an outer cover plate and a plug-in plate, a partition groove is provided between the outer cover plate and the plug-in plate, a back plate is provided on one side of the frame body, the frame connecting bolt is threadedly connected to the back plate, and a sealing gasket is provided on the side of the filling frame away from the back plate.

[0009] Furthermore, the frame body is L-shaped, with oblique cuts at both ends, the frame body includes a horizontal frame and a vertical frame, a plug-in slot is provided in the frame body, and waterproof gaskets are provided on the upper and lower surfaces of the plug-in slot.

[0010] Furthermore, the first connecting plates are arranged at two ends of the connecting frame, and the second connecting plates are arranged at a right angle to the connecting frame.

[0011] Furthermore, the first connecting plate and the second connecting plate are fixedly connected to the frame body by welding.

[0012] Furthermore, the plug board is inserted into the hollow groove, the plug board is made of foam material, the outer covering plate is made of plastic material, and one side of the outer covering plate is provided with adhesive.

[0013] (III) Beneficial effects

[0014] The beneficial effects of the utility model are:

[0015] The weight is reduced by completely hollowing out the inside of the connecting frame. Unlike the traditional photovoltaic module frame that is fixed with corner brackets, the frame body is fixed to the backplane through the connecting frame, reducing the weight brought by the corner brackets. At the same time, a filling frame is inserted into the hollow groove to seal it. In rainy and windy weather, dust, sand and rainwater cannot enter the hollow groove, which will not cause wear and rust on the inside of the photovoltaic module frame. While extending the service life cycle, it avoids sand and gravel from entering to increase the weight and reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

The frame connecting bolt 3 is threadedly connected to the back plate 6, and a sealing gasket 5d is provided on the side of the filling frame 5 away from the back plate 6.

[0025] See also Figure 3The frame body 1 is L-shaped, with oblique cuts at both ends. When the photovoltaic assembly is assembled, first a frame body 1 is fixed to the back plate 6 by the back plate connecting bolts 4, and then the solar photovoltaic panel assembly is inserted into the plug-in slot 1d in the frame body 1. At this time, the second frame body 1 is put in to cover the solar photovoltaic panel assembly, and the two frame bodies 1 are a group to form a complete frame to fix the solar photovoltaic panel assembly. It should be noted that the first connecting plate 2a and the frame connecting bolts 3 can fix the frame body on the back plate 6 while a new second connecting plate 2b can be placed on the first connecting plate 2a. The second connecting plate 2b here is not fixedly connected to the connecting frame 2a, nor is it welded to the frame body 1, but is used as an auxiliary connection. At this time, the second connecting plate 2b and the first connecting plate 2a are connected by connecting bolts 3 to perform a second fixation on a group of frame bodies 1.

[0026] The frame body 1 includes a horizontal frame 1b and a vertical frame 1c. Different from the traditional four-sided frame, the frame body 1 in the present application is a group of two to reduce the connection steps, reduce the cumbersome steps and reduce the number of connectors used. A plug-in slot 1d is provided in the frame body 1. Waterproof gaskets 7 are provided on the upper and lower surfaces of the plug-in slot 1d. The plug-in slot 1d is used to insert the solar photovoltaic module or battery cell.

[0027] The first connecting plate 2a is arranged at both ends of the connecting frame 2, and the second connecting plate 2b is arranged at a right angle to the connecting frame 2. The first connecting plate 2a plays a guiding connection role and a role in fixing the frame body 1 on the back plate 6, while the second connecting plate 2b only plays a role in fixing the frame body 1 and the connecting frame 2 on the back plate 6.

[0028] The first connecting plate 2a and the second connecting plate 2b are fixedly connected to the frame body 1 by welding. The first connecting plate 2a and the second connecting plate 2b are fixedly connected to the connecting frame 2 as a whole and are connected to the frame body 1 by welding, so that the frame body 1 is fixedly connected to the connecting frame 2.

One side of the outer covering board 5a is provided with adhesive. The function of the filling frame 5 is to close the hollow groove 1a. After the photovoltaic module or solar cell is inserted into the frame body 1 and the subsequent measures such as protective glass plate are covered on the outside, the filling frame 5 is inserted into the hollow groove 1a. At this time, the plug-in board 5b made of foam material enters the hollow groove 1a, protects the hollow groove 1a and closes it to prevent dust and sand from entering the hollow groove 1a, and at the same time isolates rainwater from entering rusted bolts, and the sealing gasket 5d closes the junction between the filling frame and the photovoltaic module or solar cell, and the outer covering board 5a extends downward to cover the gap where the filling frame 5 is connected to the frame body 1.
