In order to make the above objects, features and advantages of the present application more comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is, however, susceptible of embodiment in many other forms than those described herein and similar modifications can be made by those skilled in the art without departing from the spirit of the application, and therefore the application is not to be limited to the specific embodiments disclosed below.

Referring to fig. 1 to 7, an embodiment of the present application provides a photovoltaic module fixing apparatus 10 for fixing a photovoltaic module 30 to a purlin 20 along a predetermined direction. Specifically, the photovoltaic module fixing apparatus 10 includes: support 110, primary hitch 120, and lock 130. The main hanging member 120 has a first end and a second end disposed opposite to each other in a predetermined direction. The first end of the main hanging member 120 is connected to the supporting member 110, and a catching groove 121 for receiving the purline 20 is formed between the main hanging member and the supporting member 110. The second end of the main hanging member 120 is bent to form a main hanging portion 122 hanging on the frame 310 of the photovoltaic module 30 along a predetermined direction. Retaining members 130 extend through the brace 110 and abut purlins 20.

In the above-mentioned photovoltaic module fixing apparatus 10, since the main hanging member 120 has the first end and the second end disposed opposite to each other along the predetermined direction, the first end of the main hanging member 120 is connected to the supporting member 110, and the retaining groove 121 for accommodating the purline 20 is formed between the first end and the supporting member 110. In addition, the second end of the main hanging member 120 is bent to form the main hanging portion 122 which is hung on the frame 310 in the photovoltaic module 30 along the predetermined direction, so that the photovoltaic module 30 can be directly placed on the purline 20 during installation, the photovoltaic module fixing device 10 is placed below the purline 20 and moves along the predetermined direction, so that the purline 20 is accommodated in the holding groove 121, and meanwhile, the main hanging portion 122 is hung on the frame 310 of the photovoltaic module 30, and then the locking member 130 is utilized to penetrate through the supporting member 110 and then is abutted against the purline 20, so that the photovoltaic module fixing device 10 can be fixed on the purline 20 and the frame 310 to realize connection between the photovoltaic module 30 and the purline 20. Therefore, when the photovoltaic module fixing device 10 is used for connecting the photovoltaic module 30 and the purline 20, the frame 310 of the photovoltaic module 30 and the purline 20 do not need to be perforated, so that the photovoltaic module fixing device 10 can adapt to the installation between the photovoltaic module 30 and the purline 20 of different models, the structural strength of the frame 310 and the purline 20 cannot be influenced, and the installation efficiency can be improved while the labor intensity is effectively reduced.

Optionally, in an embodiment, only one main hanging member 120 is provided on the supporting member 110, and the main hanging member 120 is connected to the supporting member 110 to form a substantially "L" structure, and the main hanging member 120 is disposed at an angle with respect to the supporting member 110 to form a retaining groove 121. When the photovoltaic module fixing device 10 is used, the supporting member 110 is directly supported below the purline 20, the frame 310 is hung by the main hanging portion 122, and finally the locking member 130 penetrates through the supporting member 110 and then abuts against the purline 20.

Alternatively, in another implementation, the frame 310 may be secured to the purlin 20 using two photovoltaic module fixtures 10 in-line when using the photovoltaic module fixtures 10 described above. Specifically, along the axial direction of the purline 20, two photovoltaic module fixing devices 10 with an "L" structure are respectively located at the left and right sides of the purline 20, and the clamping grooves 121 of the two photovoltaic module fixing devices 10 are oppositely arranged to form a clamping groove 121 with a "U" structure in a surrounding manner. When the purline 20 is accommodated in the clamping groove 121 with the 'U' -shaped structure, both sides of the purline 20 can be limited, so that the purline 20 is prevented from falling out of the clamping groove 121. In this way, the reliability of securing the bezel 310 to the purlin 20 using the photovoltaic module securing apparatus 10 can be further improved.

Specifically, in this embodiment, in order to improve the reliability and stability of the fixation between the frame 310 and the purline 20 when the photovoltaic module fixing device 10 is connected to the frame 310 and the purline 20, as shown in fig. 7, the main hanging member 120 includes two parts. The two main hanging members 120 are disposed at the same side of the supporting member 110 at intervals, and are configured together with the supporting member 110 to form a clamping groove 121. Wherein the second ends of the two primary hangers 120 define a notch that forms a catch slot 121. Thus, as shown in fig. 5, when the photovoltaic module fixing device 10 is connected to the frame 310 and the purline 20, along the axial direction of the purline 20, both the left and right sides of the purline 20 are limited by the main hanging piece 120, so that the purline 20 can be effectively prevented from being separated from the clamping groove 121, and the reliability of fixing the frame 310 to the purline 20 is improved.

Referring to fig. 7, in one embodiment, all of the main hanging parts 122 of the two main hanging parts 120 disposed on the supporting member 110 are configured to bend in the same direction.

In general, the power generation of the photovoltaic module 30 is determined by the conversion efficiency of the solar cell and the intensity of sunlight, which is directly related to the angle between the photovoltaic module 30 and the incident direction of the sun, in addition to time and weather. When the photovoltaic module 30 is perpendicular to the incident direction of sunlight, the sunlight intensity is maximum, and the power generation amount of the photovoltaic module 30 is maximum. Therefore, in order to improve the photoelectric conversion efficiency of the photovoltaic module 30, in the photovoltaic system, the heights of the purlines 20 between the adjacent purlines 20 on the photovoltaic support are different and can be changed, so that the inclination angle of the photovoltaic module 30 mounted on the purlines 20 can be effectively adjusted, and the photovoltaic module 30 can collect more solar radiation.

In order to improve stability of the photovoltaic module 30 mounted on the purlin 20 and prevent the photovoltaic module 30 from sliding relative to the purlin 20 after being mounted, referring to fig. 5, 8 and 9, the main hanging portion 122 is provided with anti-slip teeth 1221 on a surface facing the supporting member 110. The anti-slip tooth 1221 is configured to interference fit with the bezel 310 to limit movement of the bezel 310 relative to the main catch 122.

Specifically, when the purline 20 is clamped in the clamping groove 121, the main hanging portion 122 is hung on the frame 310, and the locking member 130 passes through the supporting member 110 to abut against and pre-tighten the purline 20, the anti-slip teeth 1221 contact the frame 310 and apply a force to the frame 310 in a direction close to the purline 20, at this time, the area where the frame 310 contacts the anti-slip teeth 1221 is stressed to elastically deform to form a tooth pit, and the tooth pit is meshed with the anti-slip teeth 1221 to limit the movement of the frame 310 relative to the main hanging portion 122, so that the stability of fixing the frame 310 on the purline 20 is improved.

Specifically, in the present embodiment, the extending direction of the tooth grooves for the anti-slip tooth 1221 is the same as the length direction of the purline 20.

In order to improve the convenience and reliability of the connection of the locking member 130, referring to fig. 5 and 7, in an embodiment, the locking member 130 is provided with external threads, and the supporting member 110 is provided with a threaded hole 111. The retaining member 130 is threadably coupled within the threaded bore 111 and is configured to abut the purlin 20.

To further enhance the stability of the photovoltaic module 30 secured to the purlin 20, referring to fig. 3, 6 and 7, in one embodiment, the support 110 is provided with at least two threaded holes 111. And the locking members 130 are screw-coupled with the screw holes 111 in one-to-one correspondence.

Specifically, in one embodiment, retaining member 130 is a retaining screw or retaining bolt.

In order to improve the structural strength of the photovoltaic module fixing device 10 and further improve the stability of the installation of the photovoltaic module 30, in an embodiment, the main hanging member 120 is integrally formed on the supporting member 110.

To further increase the structural strength of the photovoltaic module fixture 10 and extend its service life, in one embodiment, the support member 110 and each of the primary hangers 120 are made of a metallic material.

Alternatively, in another embodiment, the support 110 and each of the primary hangers 120 are made of a non-metallic material for cost savings.

In one embodiment, the photovoltaic module fixture 10 further includes a secondary hanger (not shown). The secondary hitches are provided on the support member 110 and are located on the same side of the support member 110 as the primary hitches 120. And the auxiliary hanging piece is positioned at one side of the main hanging piece 120, which is away from the clamping groove 121. One end of the auxiliary hanging member, which is far away from the supporting member 110, is bent to form an auxiliary hanging portion which is hung on the frame 310 in the photovoltaic module 30 along a predetermined direction. In this way, the support points for the frame 310 of the photovoltaic module 30 are increased, and the stability of the photovoltaic module 30 mounted to the purline 20 is further improved.

Optionally, in an embodiment, at least two auxiliary hanging members are provided, and at least one auxiliary hanging member is provided on a side of each main hanging member 120 facing away from the clamping groove 121.

Referring to fig. 1 to 3, the present application further provides a photovoltaic bracket, including: purlin 20, photovoltaic module 30, and photovoltaic module fixture 10 as described above. The photovoltaic module 30 is secured to the purlin 20 by the photovoltaic module securing apparatus 10.
