DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] Combine the following Figure 1-Figure 7 A clamp according to an embodiment of the first aspect of the present application is described.

[0028] Figure 1 FIG. 2 shows a schematic diagram of a three-dimensional structure of a clamp according to an embodiment of the present application. Figure 1As shown, the clamp 10 includes a photovoltaic connection plate 100 , a first clamping plate 200 and a second clamping plate 300 .

[0029] Specifically, the photovoltaic connection plate 100 is used to connect the photovoltaic modules, and the photovoltaic connection plate 100 extends horizontally. The first clamping plate 200 is connected to the bottom of the photovoltaic connection plate 100 and is perpendicular to the photovoltaic connection plate 100. The second clamping plate 300 is arranged opposite to the first clamping plate 200, and the second clamping plate 300 and the first clamping plate 200 are connected by fasteners, and the roof lock edge structure is clamped between the second clamping plate 300 and the first clamping plate 200.

[0030] It should be noted that "the photovoltaic connection panel 100 extends horizontally" should be understood in a broad sense in the present application, which means that the overall installation direction of the photovoltaic connection panel 100 is horizontal installation, and the photovoltaic connection panel 100 is parallel to the horizontal plane as a whole. The surface of the photovoltaic connection panel 100 can be a flat surface or an uneven curved surface, as long as the photovoltaic connection panel 100 is parallel to the horizontal plane as a whole.

[0031] For example, in combination Figure 1 , the bottom surface of the photovoltaic connection plate 100 can be parallel to the horizontal plane, and the top surface of the photovoltaic connection plate 100 can be a curved surface with different concave and convex shapes. The first clamping plate 200 and the photovoltaic connection plate 100 can form a "T"-shaped structure, and the first clamping plate 200 can be integrally formed with the photovoltaic connection plate 100. A first mounting hole can be formed on the first clamping plate 200, and a second mounting hole can be formed on the second clamping plate 300. The fastener can be passed through the first mounting hole and the second mounting hole to the first clamping plate 200 and the second clamping plate 300, thereby achieving a fixed connection between the first clamping plate 200 and the second clamping plate 300. Among them, the fastener can be a threaded fastener, such as a stainless steel bolt, to ensure a secure connection between the first clamping plate 200 and the second clamping plate 300 while avoiding rust. The central axis of the fastener is parallel to the horizontal plane.

[0032] According to the clamp 10 of the embodiment of the present application, the photovoltaic connection plate 100 can be connected to the photovoltaic module, and the first clamping plate 200 and the second clamping plate 300 can clamp the roof locking structure, so that the photovoltaic module can be installed on the roof module. Moreover, by connecting the first clamping plate 200 and the second clamping plate 300 through fasteners, a secure connection between the first clamping plate 200 and the second clamping plate 300 can be achieved, and the clamp 10 is prevented from being separated from the roof locking structure, so that the installation stability of the photovoltaic module can be effectively guaranteed, thereby improving safety and long-term reliability. In addition, the structure of the clamp 10 is simple and the cost is low.

[0033] Figure 2 Show Figure 1 A front view of the fixture 10 shown in ; Figure 3 Show Figure 1 A rear view of the clamp 10 is shown in FIG. In one embodiment, in combination with Figure 1-Figure 3 , the first clamping plate 200 may be provided with a first protrusion 210 on one side facing the second clamping plate 300, and a first groove is defined between the first protrusion 210 and the photovoltaic connection plate 100; the second clamping plate 300 may be provided with a second protrusion 310 on one side facing the first clamping plate 200, and the second protrusion 310 fits in the first groove. Figure 1-Figure 3 In the example, when the fastener is a threaded fastener such as a stainless steel bolt, during the assembly process of the first clamping plate 200 and the second clamping plate 300, the second protrusion 310 is firstly matched in the first groove, so that the first mounting hole on the first clamping plate 200 is opposite to the second mounting hole on the second clamping plate 300, and then the fastener is passed through the first mounting hole and the second mounting hole respectively, and the fastener is tightened. In the process of gradually tightening the fastener, the force between the second protrusion 310 and the inner wall of the first groove gradually increases. Among them, a limiting groove 230 can be provided on the side of the first clamping plate 200 away from the second clamping plate 300, and the fastener is located in the limiting groove 230.

[0034] In this embodiment, by setting the above-mentioned first protrusion 210, first groove and second protrusion 310, the second protrusion 310 can abut against the inner wall of the first groove, thereby increasing the clamping force and ensuring that the roof locking structure can be clamped between the first clamping plate 200 and the second clamping plate 300.

[0035] In one embodiment, a third protrusion 220 spaced apart from the first protrusion 210 is further provided on the side of the first clamping plate 200 facing the second clamping plate 300, and a second groove is defined between the third protrusion 220 and the surface of the first clamping plate 200; a fourth protrusion 320 spaced apart from the second protrusion 310 is provided on the side of the second clamping plate 300 facing the first clamping plate 200, and the fourth protrusion 320 fits in the second groove.

[0036] For example, during the assembly of the first clamping plate 200 and the second clamping plate 300, the second protrusion 310 is first fitted into the first groove and the fourth protrusion 320 is fitted into the second groove, so that the first mounting hole on the first clamping plate 200 is opposite to the second mounting hole on the second clamping plate 300, and then the fastener is passed through the first mounting hole and the second mounting hole respectively, and the fastener is tightened. In the process of gradually tightening the fastener, the force between the second protrusion 310 and the inner wall of the first groove gradually increases, and the force between the fourth protrusion 320 and the inner wall of the second groove gradually increases.

[0037] In this embodiment, by setting the above-mentioned third protrusion 220, second groove and fourth protrusion 320, the fourth protrusion 320 can abut against the inner wall of the second groove, thereby further improving the clamping force and ensuring that the roof locking structure can be clamped between the first clamping plate 200 and the second clamping plate 300.

[0038] In one embodiment, referring to Figure 2 and Figure 3 The fourth protrusion 320 may include a first inclined surface 321 disposed close to the second protrusion 310 and a second inclined surface 322 disposed away from the second protrusion 310, the slope of the first inclined surface 321 is greater than the slope of the second inclined surface 322, the roof edge locking structure is disposed close to the second inclined surface 322, and the third protrusion 220 is disposed close to the first inclined surface 321. In this way, the second inclined surface 322 is smoother than the first inclined surface 321, and can effectively stop and limit the roof edge locking structure, preventing the roof edge locking structure from moving along the second inclined surface 322, so that the roof edge locking structure can be more stably clamped between the first clamping plate 200 and the second clamping plate 300.

[0039] Figure 4 Show Figure 1 A left side view of the clamp 10 shown in FIG. Figure 5 Show Figure 1 In one embodiment, the clamp 10 is shown in the right side view. Figure 1 , Figure 4 and Figure 5 The first clamping plate 200 has a first area between the first protrusion 210 and the third protrusion 220 and a second area on the side of the third protrusion 220 away from the first protrusion 210; the second clamping plate 300 has a third area between the second protrusion 310 and the fourth protrusion 320 and a fourth area on the side of the fourth protrusion 320 away from the second protrusion 310, wherein the fastener is connected to the first area and the third area, and the roof lock edge structure is clamped between the second area and the fourth area. In this way, the spatial layout of the clamp 10 is more reasonable, so that the fastener can be staggered with the roof lock edge structure to avoid interference.

[0040] In one embodiment, Figure 1-Figure 3As shown, along the arrangement direction of the first clamping plate 200 and the second clamping plate 300, the size of the second protrusion 310 is greater than the size of the fourth protrusion 320. In this way, the size of the second protrusion 310 in the arrangement direction of the first clamping plate 200 and the second clamping plate 300 is larger, and the cooperation between the second protrusion 310 and the first groove can effectively limit the relative movement of the first clamping plate 200 and the second clamping plate 300. Moreover, the size of the fourth protrusion 320 in the arrangement direction of the first clamping plate 200 and the second clamping plate 300 is smaller, which can avoid interference between the fourth protrusion 320 and the third protrusion 220, and facilitate the assembly of the clamp 10.

[0041] In one embodiment, the roof locking structure includes a first part and a second part arranged vertically, the thickness of the first part is greater than the thickness of the second part, and the first part is located above the second part, and the first part is sandwiched between the first clamping plate 200 and the second clamping plate 300 (not shown). Exemplarily, a flange structure may be provided on the second clamping plate 300, the flange structure and the second protrusion 310 are provided on the same side of the second clamping plate 300, and the flange structure is located on the side of the fourth protrusion 320 away from the second protrusion 310. The first part of the roof locking structure may be located between the fourth protrusion 320 and the flange structure.

[0042] In this embodiment, the first part is clamped between the first clamping plate 200 and the second clamping plate 300. Since the thickness of the first part is relatively large, the first clamping plate 200 and the second clamping plate 300 can clamp the roof edge locking structure with greater force, thereby ensuring clamping stability.

[0043] In one embodiment, the orthographic projection of the first clamping plate 200 on the horizontal plane is located within the orthographic projection of the photovoltaic connection plate 100 on the horizontal plane, and the orthographic projection of the second clamping plate 300 on the horizontal plane is located within the orthographic projection of the photovoltaic connection plate 100 on the horizontal plane. In this way, the photovoltaic connection plate 100 can cover the first clamping plate 200 and the second clamping plate 300, so that the photovoltaic connection plate 100, the first clamping plate 200 and the second clamping plate 300 occupy a smaller overall space in the horizontal direction, which is convenient for installation.

[0044] Figure 6 Show Figure 1 A top view of the fixture 10 shown in FIG. Figure 7 Show Figure 1 A bottom view of the fixture 10 shown in FIG. Figure 1 , Figure 6 and Figure 7As shown, the photovoltaic connection plate 100 is provided with an elongated hole 110 for connecting the photovoltaic module, and the elongated hole 110 penetrates the photovoltaic connection plate 100 along the thickness direction of the photovoltaic connection plate 100. For example, the photovoltaic module can be connected to the photovoltaic connection plate 100 through a photovoltaic bracket. The setting of the photovoltaic bracket enables the clamp 10 to adapt to photovoltaic modules of different shapes and sizes. The setting of the elongated hole 110 allows the operator to properly adjust the photovoltaic bracket, thereby playing the role of adjusting the photovoltaic module. Among them, the elongated hole 110 can extend along the arrangement direction of the first clamping plate 200 and the second clamping plate 300.

[0045] In this embodiment, the stress of the photovoltaic module can be released by providing the elongated holes 110, thereby ensuring the quality and reliability of the photovoltaic module. In addition, the clamping force and position of the photovoltaic module can be adjusted through the elongated holes 110, thereby ensuring the installation flatness of the photovoltaic module and avoiding errors.

[0046] In one embodiment, the photovoltaic connection plate 100, the first clamping plate 200 and the second clamping plate 300 can all be aluminum alloy parts. Therefore, since aluminum alloy is a lightweight material, the weight of the clamp 10 is small and easy to install. In addition, the clamp 10 can have high corrosion resistance and high strength, and is not easy to oxidize and corrode, thereby extending the service life of the clamp 10.

[0047] The second aspect of the present application provides a roof system, including a roof assembly (not shown), a photovoltaic assembly (not shown) and a clamp 10 of any of the above embodiments. The roof assembly includes a roof edge locking structure. The photovoltaic connecting plate 100 of the clamp 10 is connected to the photovoltaic assembly, and the roof edge locking structure is clamped between the second clamping plate 300 and the first clamping plate 200 of the clamp 10. Exemplarily, the roof assembly can be a 360-degree bite edge locking roof assembly. The photovoltaic assembly can be a double-glass photovoltaic assembly to improve the solar energy conversion efficiency.

[0048] According to the roof system of the embodiment of the present application, the photovoltaic module can be installed on the roof module by using the above-mentioned clamp 10. Moreover, the installation stability of the photovoltaic module can be effectively guaranteed, thereby improving safety and long-term reliability.
