Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic track beam connector. Background Art

[0002] Photovoltaic technology refers to a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert solar energy into electricity. Simply put, when sunlight strikes certain materials (such as semiconductors like silicon), voltage and current are generated within the materials, thereby converting solar energy into electricity. This technology is widely used in solar photovoltaic power generation systems and is a clean, renewable energy source. The mounting brackets for photovoltaic modules are typically made of aluminum frames, with bolts or slots connecting the encapsulated photovoltaic modules to the support frame. This bracket or slot-type connection is mostly suitable for sloping rooftops. Installing photovoltaic modules on building facades requires overcoming the weight of the modules, and the danger of falling in high-rise and super-high-rise buildings is significant. For this reason, photovoltaic companies rarely install photovoltaic panels on building facades. However, large cities face land shortages and high electricity demand. Utilizing the largest exterior surfaces of high-rise and super-high-rise structures for power generation offers significant economic and environmental benefits. In addition, structural components are allowed to have a certain degree of deformation under specific horizontal loads (such as earthquake loads and wind loads), but photovoltaic panels are a brittle material. Excessive structural deformation may cause sudden shattering of the photovoltaic panels, making the photovoltaic power generation function ineffective and even causing secondary disasters.

[0003] The installation of the beam track is very important. During the connection and installation process of the existing track beam, the connectors are easy to detach from the track beam. In the early stage of installation, the distance between the connectors needs to be adjusted according to the size of the photovoltaic panel. The existing connectors are inconvenient to move on the beam, are not firmly fixed, and have an unstable structure. Therefore, we propose a photovoltaic track beam connector to solve the above problems. Utility Model Content

[0004] The utility model provides a photovoltaic track beam connector, which solves the technical problems of the current photovoltaic beam track connector being easily separated from the track beam and having an unstable structure.

[0005] In order to solve the above technical problems, the utility model provides a photovoltaic rail crossbeam connector, including a rail body and a connector body that is movably mounted on the rail body and can slide freely along the rail body. The cross-section of the rail body is H-shaped, and the cross-section of the connector body is a concave structure. Fastening bolts are provided on both sides of the connector body, and the connector body is fixed to the rail body by fastening bolts.

[0006] Preferably, the connector body includes a transverse plate, a side plate and a hook plate, the side plates are provided on both sides of the transverse plate, the side of the side plate away from the transverse plate is provided with a hook plate, and the connector body is formed by integral bending and die casting.

[0007] The above technical solution is adopted: the connector body includes a horizontal plate, a side plate and a hook plate, side plates are provided on both sides of the horizontal plate, and a hook plate is provided on the side of the side plate away from the horizontal plate. The connector body is made of one-piece bending and die-casting. From one end of the track body, the connector body is inserted into the track body, the horizontal plate is attached to the track body, the side plates on both sides are attached to the side edges of the track body, and the hook-shaped plate is attached to the track body, which can effectively prevent the connector from detaching from the track body. In addition, the connector is integrally bent and die-cast, which also ensures the strength and hardness of the connector.

[0008] Preferably, the transverse plate is provided with mounting holes, and at least two mounting holes are provided and are distributed linearly.

[0009] The above technical solution is adopted: mounting holes are opened on the horizontal plate, at least two mounting holes are opened and linearly distributed, and the mounting holes are used for fixing the connectors and the photovoltaic panels.

[0010] Preferably, threaded holes are provided on the side panels, and the threaded holes penetrate the side panels and are arranged linearly.

[0011] The above technical solution is adopted: threaded holes are opened on the side panels, and the threaded holes are arranged linearly through the side panels, which makes it convenient to insert the fastening bolts into the threaded holes. The linear arrangement enables multiple fastening bolts to be set, thereby achieving a better fixing effect on the connector body.

[0012] Preferably, fixing grooves are provided on both sides of the middle portion of the rail body, and the threads of the fastening bolts pass through the side plates and interfere with the fixing grooves.

[0013] The above technical solution is adopted: fixing grooves are opened on both sides of the middle part of the rail body, and the threads of the fastening bolts pass through the side plates and conflict with the fixing grooves. By tightening the fastening bolts, one end of the fastening bolts conflicts with the fixing grooves, increasing the friction between the fixing grooves and the fastening bolts, thereby fixing the connecting parts on the rail body.

[0014] Preferably, a clamping cavity is formed between the hook-shaped plate and the side plate, and the height of the clamping cavity is greater than the height of the track body.

[0015] The above technical solution is adopted: a clamping cavity is formed between the hook plate and the side plate, which facilitates the clamping of the connector body on the track body. The height of the clamping cavity is greater than the height of the track body, which facilitates the connector body to move freely on the track body.

[0016] Preferably, the fastening bolts are hexagonal bolts.

[0017] The above technical solution is adopted: by using a hexagonal bolt as the fastening bolt, the hexagonal bolt is more universal and has a wider adaptability.

[0018] Compared with the related art, the present invention has the following beneficial effects:

[0019] 1. Compared with the traditional photovoltaic track beam connector, the utility model is provided with a connector with a concave structure that is clamped on the track body, wherein the structural shape of the connector can be firmly clamped on the track body and can be moved along the track body, thereby adjusting the distance between the two connectors on the track body, thereby realizing the connector fixing photovoltaic panels of different sizes. At the same time, after adjusting the position of the connector on the track body, it is tightened by fastening bolts on both sides of the connector, so that the fastening bolts are against the track body, thereby fixing the connector on the track body and no longer moving, so that the connector is firmly fixed on the track beam and the structure is stable.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1-4As shown, a photovoltaic track beam connector includes a track body 1 and a connector body 2 that is movably mounted on the track body 1 and can slide freely along the track body 1. The track body 1 has an H-shaped cross section, and the connector body 2 has a concave cross section. Fastening bolts 3 are provided on both sides of the connector body 2, and the connector body 2 is fixed to the track body 1 by the fastening bolts 3.

[0028] The cross-section of the track body 1 is H-shaped, and the cross-section of the connector body 2 is a concave structure. Fastening bolts 3 are provided on both sides of the connector body 2. The connector body 2 is fixed to the track body 1 by the fastening bolts 3, and is clamped on the track body 1 by the connector with a concave structure. The structural shape of the connector can be firmly clamped on the track body 1, and can be moved along the track body 1, so as to adjust the distance between the two connectors on the track body 1, thereby realizing the connector fixing photovoltaic panels of different sizes. At the same time, after adjusting the position of the connector on the track body 1, it is then tightened by the fastening bolts 3 on both sides of the connector, so that the fastening bolts 3 are against the track body 1, thereby fixing the connector on the track body 1 and no longer moving, so that the connector is firmly fixed on the track beam and the structure is stable.

[0029] Example 2

[0030] like Figures 1-4 As shown, the connector body 2 includes a transverse plate 21, a side plate 22 and a hook-shaped plate 23. Side plates 22 are provided on both sides of the transverse plate 21. A hook-shaped plate 23 is provided on the side of the side plate 22 away from the transverse plate 21. The connector body 2 is formed by integral bending and die-casting. A mounting hole 5 is provided on the transverse plate 21. There are at least two mounting holes 5 and they are linearly distributed. Threaded holes 6 are provided on the side plates 22. The threaded holes 6 penetrate the side plates 22 and are linearly arranged. Fixing grooves 4 are provided on both sides of the middle of the track body 1. The fastening bolts 3 are threaded through the side plates 22 and conflict with the fixing grooves 4. A clamping cavity 24 is formed between the hook-shaped plate 23 and the side plates 22. The height of the clamping cavity 24 is greater than the height of the track body 1. The fastening bolts 3 are hexagonal bolts. Hexagonal bolts are more universal and have a wider adaptability.

[0031] The connector body 2 includes a transverse plate 21, a side plate 22 and a hook-shaped plate 23. The side plates 22 are provided on both sides of the transverse plate 21, and the hook-shaped plate 23 is provided on the side of the side plate 22 away from the transverse plate 21. The connector body 2 is made of an integral bending die-casting. From one end of the track body 1, the connector body 2 is clamped into the track body 1. The transverse plate 21 is attached to the track body 1, and the side plates 22 on both sides are attached to the side edges of the track body 1. The hook-shaped plate 23 is clamped on the track body 1, which can effectively prevent the connector from being separated from the track body 1. In addition, the connector is integrally bent and die-cast, which also ensures the strength and hardness of the connector.

[0032] A mounting hole 5 is provided on the cross plate 21, and at least two mounting holes 5 are provided and are linearly distributed. The mounting holes 5 are used for fixing and installing between the connector and the photovoltaic panel. A fixing groove 4 is provided on both sides of the middle part of the track body 1. The thread of the fastening bolt 3 passes through the side plate 22 and conflicts with the fixing groove 4. By tightening the fastening bolt 3, one end of the fastening bolt 3 conflicts with the fixing groove 4, increasing the friction between the fixing groove 4 and the fastening bolt 3, thereby fixing the connector to the track body 1. A clamping cavity 24 is formed between the hook plate 23 and the side plate 22, which facilitates the clamping of the connector body 2 on the track body 1. The height of the clamping cavity 24 is greater than the height of the track body 1, which facilitates the connector body 2 to move freely on the track body 1.

[0033] Working principle: Figure 1-4 As shown, the connector body 2 is clamped in along one end of the track body 1, so that the cross plate 21 is fitted on the top of the track body 1, the side plates 22 on both sides are fitted on both sides of the track body 1, and the hook-shaped plates 23 are clamped on the bottom of the track body 1. This clamping method ensures that the connector body 2 will never separate from the track body 1 when the track body 1 is placed horizontally. Since there is a clamping cavity 24 and the height of the clamping cavity 24 is greater than the height of the track body 1, the connector body 2 slides more smoothly on the track body 1, which is convenient for adjusting the distance between two adjacent connector bodies 2 on the track body 1, thereby facilitating the connector body 2 to fix photovoltaic panels of different sizes. By opening a mounting hole 5 on the connector body 2, the bolts on the photovoltaic panel are inserted into the mounting hole 5, and then fixed with nuts, the photovoltaic panel is fixed to the connector body 2. By opening threaded holes 6 on both sides of the connector body 2, the connector body 2 is fixed to the track body 1 by tightening the bolts 3.
