[0031] Referring to Figures 1 to 3, a fixing device 100 provided in an embodiment of the present application is used to connect the support member 200 with the frame of the photovoltaic component 300. The fixing device 100 includes a first clamp 110, a second clamp 120 and a first fastener 160; the second clamp 120 is arranged opposite to the first clamp 110; at least one of the second clamp 120 and the first clamp 110 is constructed with a first mounting portion 121, and the first mounting portion 121 is used to connect with the frame of the photovoltaic component 300; one end of the first fastener 160 passes through one of the first clamp 110 and the second clamp 120, and abuts against the other of the first clamp 110 and the second clamp, so that the first clamp 110 and the second clamp 120 jointly enclose a clamping groove 111 for mounting the support member 200.

[0032] The fixing device 100 is used to install the support member 200 through the clamping groove 111 formed by the first clamp 110 and the second clamp 120, so as to connect the support member 200 with the fixing device 100. At the same time, the fixing device 100 can be connected to the frame of the photovoltaic module 300 through the first mounting portion 121, thereby fixing the photovoltaic module 300 on the support member 200. Taking the example of the first fastener 160 passing through the first clamp 110 and abutting against the second clamp 120, through this arrangement, not only the connection and fixation between the first clamp 110 and the second clamp 120 is achieved, but also the gap between the first clamp 110 and the second clamp 120 can be adjusted through the first fastener 160, so that the size of the clamping groove 111 formed therebetween is adapted to the size of the support member 200, thereby clamping the support member 200, thereby improving the connection stability between the photovoltaic component 300 connected to the fixing device 100 and the support member 200, reducing the possibility of rotation of the fixing device 100 and the photovoltaic component 300 relative to the support member 200, and improving the connection strength of the node; at the same time, by adjusting the size of the clamping groove 111, it is also possible to adapt to supports 200 of different diameters, thereby improving its adaptability.

[0033] Referring to Figures 1 to 2, in one embodiment, the first clamp 110 includes a first body 113 and a first connecting portion 150 connected to the end of the first body 113; a first fastening hole 154 is constructed on the first connecting portion 150; the second clamp 120 includes a second body 123 and a second connecting portion 170 connected to the end of the second body 123, the first body 113 and the second body 123 are arranged opposite to each other, so that one end of the first fastener 160 can pass through the first fastening hole 154 and abut against the second connecting portion 170; the first body 113 and the second body 123 jointly enclose a clamping groove 111 that is adapted to the size of the support member 200.

[0034] Specifically, the first body 113 is approximately a straight-line structure, the second body 123 is approximately a T-shaped structure, and the second body 123 is provided with the first mounting portion 121. The first body 113 is partially protruded outward, and the inner wall of the protruding portion is recessed relative to the first body 113, forming a first groove; the second body 123 is partially protruded outward, and the inner wall of the protruding portion is recessed relative to the second body 123, forming a second groove. The first groove and the second groove cooperate to form a clamping groove 111, which is used to fix the support member 200. In other embodiments, the thickness of the first body 113 and the second body 123 can also be increased, and the first body 113 and the second body 123 can be directly grooved without providing a local protruding portion.

[0035] Referring to FIG. 2 , in one embodiment, at least one of the first groove and the second groove is provided with a rubber pad 180 for contacting the support member 200. For example, in the embodiment shown in FIG. 2 , the groove wall of the first groove and the groove wall of the second groove are both connected with the rubber pad 180, and the rubber pad 180 is provided to protect the support member 200. The rubber pad 180 can be a rubber pad 180 or the like.

[0036] Referring to FIGS. 1 to 3 , in one embodiment, the first connection portion 150 includes a bending portion 151 and a limiting portion 152, wherein the bending portion 151 is bent from the first body 113 in a direction close to the second clamp 120; the limiting portion 152 is connected to an end of the bending portion 151 away from the first body 113, and the limiting portion 152 extends from the bending portion 151 in a direction close to the clamping groove 111; the limiting portion 152 is used to connect with the second connection portion 170. Furthermore, the first body 113, the bending portion 151 and the limiting portion 152 cooperate to form a receiving groove 153; the second connection portion 170 is disposed in the receiving groove 153, and a first fastening hole 154 is provided on the limiting portion 152 for the first fastener 160 to pass through. In this way, the bending portion 151 can limit the second connecting portion 170 to prevent the second clamp 120 from rotating relative to the first clamp 110, thereby ensuring the connection effect between the second clamp 120 and the first clamp 110, thereby improving the reliability of the support member 200 fixed in the clamping groove 111 and enhancing the stability of the fixing device 100.

[0037] In other embodiments, the second connecting portion 170 may be connected to the side of the limiting portion 152 away from the first body 113, that is, the second connecting portion 170 is located outside the accommodating groove 153, and a second fastening hole is provided on the second connecting portion 170, so that the first fastening member 160 can pass through the second fastening hole and the first fastening hole 154 in sequence, thereby connecting and fixing the first clamp 110 and the second clamp 120.

[0038] Referring to FIGS. 1 to 3 , in one embodiment, a first clamp 110 is provided with a first clamping portion 112 at an end away from the first connection portion 150; and a second clamp 120 is provided with a second clamping portion 122 for clamping and cooperating with the first clamp 112 at an end away from the second connection portion 170. One of the first clamp 112 and the second clamp 122 is a clamping protrusion, and the other is a clamping groove. Through the cooperation of the clamping protrusion and the clamping groove, the connection stability of the first clamp 110 and the second clamp 120 is further improved, thereby ensuring the stability of the clamping groove 111 clamping the support member 200. Specifically, the first clamp 110 may be provided with a clamping protrusion, and the second clamp 120 may be provided with a clamping groove. Of course, the second clamp 120 may also be provided with a clamping protrusion, and the first clamp 110 may be provided with a clamping groove.

[0039] As shown in FIG2 , in one embodiment, the clamping protrusion is a spherical protrusion, and the clamping groove is a spherical groove. By setting the clamping protrusion and the clamping groove to be spherical, the clamping of the two is smoother, and after the spherical protrusion is clamped into the spherical groove, the possibility of the spherical protrusion falling out of the spherical groove can be reduced, thereby improving the connection effect between the first clamp 110 and the second clamp 120.

[0040] In one embodiment, a plurality of clamping grooves 111 are provided, and the radial dimensions of each clamping groove 111 are different. Thus, when a clamping groove 111 cannot be well adapted to the size of the support member 200, the support member 200 can be connected to a clamping groove 111 of other sizes, thereby ensuring the connection stability between the support member 200 and the fixing device 100 and reducing the possibility of relative rotation between the two.

[0041] As shown in FIG2 , in one embodiment, the support member 200 may be a steel cable. The first mounting portion 121 is provided on the second clamp 120, and the first mounting portion 121 is a mounting hole, and a through hole is also provided on the frame of the photovoltaic module 300; the fixing device 100 further includes a second fastener 400, and the second fastener 400 passes through the through hole and the mounting hole in sequence, thereby connecting the second clamp 120 with the frame of the photovoltaic module 300, thereby achieving the connection and fixation of the fixing device 100 with the photovoltaic module 300. In other embodiments, the first mounting portion 121 may be provided on the first clamp 110, or the first clamp 110 and the second clamp 120 may respectively provide the first mounting portion 121 to connect with the frame of the photovoltaic module 300.

[0042] Furthermore, an embodiment of the present application also provides a photovoltaic system, including a support 200, a photovoltaic module 300 and the above-mentioned fixing device 100. The support 200 is installed through the clamping groove 111 formed by the first clamp 110 and the second clamp 120, and the fixing device 100 is connected to the frame of the photovoltaic module 300 through the first mounting portion 121, thereby fixing the photovoltaic module 300 on the support 200. The connection and fixation between the first clamp 110 and the second clamp 120 are achieved by the first fastener 160, and the gap between the first clamp 110 and the second clamp 120 can be adjusted by the first fastener 160, so that the size of the clamping groove 111 formed therebetween is adapted to the size of the support member 200, thereby clamping the support member 200, thereby improving the connection stability between the photovoltaic component 300 connected to the fixing device 100 and the support member 200, reducing the possibility of rotation of the photovoltaic component 300 relative to the support member 200, and improving the connection strength of the node; at the same time, by adjusting the size of the clamping groove 111, it is also possible to adapt to supports 200 of different diameter specifications, thereby improving its adaptability to use.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
