[0004] As a first aspect of the embodiments of this application, this application provides a pressure block applied to a photovoltaic system. The photovoltaic system includes a C-shaped steel, a connector, and a photovoltaic frame. The C-shaped steel forms a strip opening, and the connector is located inside the strip opening and hooks onto the two side edges of the C-shaped steel. The photovoltaic frame is disposed on the strip opening, and the photovoltaic frame includes a convex edge. The pressure block includes a pressure block body, and the pressure block body includes a first surface.

[0006] In one embodiment, the ridge is mounted on the strip opening, and the height of the ridge protruding from the first surface is higher than the height of the hook protruding from the first surface, and the height difference is adapted to the height of the ridge.

[0007] In one embodiment, the cross-section of the protrusion along the direction perpendicular to the hook edge is trapezoidal, with the long side of the trapezoid close to the first surface.

[0008] In one embodiment, the width of the convex strip is 2 / 5 to 3 / 5 of the width of the pressing block body.

[0009] As a second aspect of the embodiments of this application, this application provides a connector applied to a photovoltaic system. The photovoltaic system further includes a C-shaped steel, a pressure block, and a photovoltaic frame. The C-shaped steel forms a strip opening, and the photovoltaic frame is disposed on the strip opening. The photovoltaic frame includes a convex edge, and the pressure block is mounted on the strip opening and pressed against the convex edge. The connector includes a connecting plate and at least two hook plates, which are respectively hinged to opposite sides of the connecting plate. The connecting plate is located inside the strip opening, and the at least two hook plates respectively hook onto two side edges of the C-shaped steel.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] like Figures 1 to 5 As shown, this application embodiment provides a clamping block 100, which can be applied to a photovoltaic system. The photovoltaic system includes a C-shaped steel 300, a connector 200, and a photovoltaic frame 400. The photovoltaic panel is snapped into the slot 401 in the photovoltaic frame 400. The photovoltaic system also includes a photovoltaic support frame, which is erected on the ground, roof, or in a ground environment where the photovoltaic system is to be installed. The C-shaped steel 300 can be a purlin, such as... Figure 1 The structure shown depicts a purlin fixedly connected to the photovoltaic support, which can be achieved through threaded fastening. The C-shaped steel 300 can also be as shown... Figure 5 The diagram shows a corrugated steel sheet structure. C-shaped steel 300 forms a strip opening 301, and connectors 200 are located within the strip opening 301 and hook onto the two side edges of the C-shaped steel 300. A photovoltaic frame 400 is mounted on the strip opening 301. To ensure the photovoltaic frame 400 is securely installed, the upper surface of the C-shaped steel 300 can be designed as follows: Figure 1The photovoltaic frame 400 has a planar shape. The photovoltaic frame 400 includes a protruding edge 410; the pressing block 100 includes a pressing block body, the pressing block body including a first surface, the first surface being as shown... Figure 1 or Figure 2 The surface facing downwards. The opposite ends of the pressure block body respectively form hook edges 110 protruding from the first surface, and the hook edges 110 are pressed onto the convex edge 410; the pressure block 100 is fastened to the connector 200 to fasten the photovoltaic frame 400 and the C-shaped steel 300.

[0028] In existing methods, the photovoltaic frame 400 and the connector 200 are typically fastened directly with fasteners, such as by bolts passing through the photovoltaic frame 400 and the connector 200 to fasten the C-shaped steel 300 to the photovoltaic frame 400. The assembly method of the C-shaped steel 300 and the photovoltaic frame 400 differs slightly from the method illustrated in the embodiments of this application. In these installation methods, fasteners such as the bolt 500 need to avoid certain specific locations, preventing tightening in the middle. Furthermore, the locations where the bolt 500 passes have significant hollow portions, making this fastening method prone to loosening. Additionally, refer to... Figure 2 Multiple photovoltaic frames 400 are arranged adjacent to each other. The aforementioned fixing method requires at least one bolt 500 to fix each photovoltaic frame 400, which can easily cause the photovoltaic frame 400 to rotate around the bolt 500, affecting its firmness.

[0029] In this embodiment, a pressure block 100 is pressed onto the protruding edge 410 of two adjacent photovoltaic frames 400. Fasteners are then used to secure the pressure block 100 to the connector 200, thus securing the photovoltaic frame 400 to the C-shaped steel 300. This method facilitates fastening, and the fasteners can be secured from the middle of the two photovoltaic frames 400. The hook edge 110 of the pressure block 100 presses against the protruding edge 410 of the photovoltaic frame 400, ensuring that the force between them acts along at least a line, rather than at a single point. This results in a stronger load-bearing capacity for the fixed photovoltaic frame 400. Furthermore, the bolt 500 can pass through the middle of the strip opening 301 for fastening, preventing it from shifting to either side and improving the stability and balance of the photovoltaic system.

[0030] In one embodiment, a protrusion 120 is formed in the middle of the pressing block body, and the pressing block body is provided with a through hole penetrating the protrusion 120.

[0031] Bolt 500 passes through the through hole to fasten the pressure block 100 and the connector 200. By setting a convex strip 120 shape in the middle of the pressure block body, the position where the bolt 500 passes is a solid area. After the pressure block 100 and the connector 200 are tightened and compacted, the pressure block has little or no room for movement, which makes the stability after tightening and compaction more guaranteed.

[0032] Furthermore, when the pressure block 100 is placed above the strip opening 301, the protruding strip 120 can support the C-shaped steel 300, and there is an interaction force between the C-shaped steel 300 and the protruding strip 120, so that the C-shaped steel 300 and the photovoltaic frame 400 achieve mutual force balance; this avoids the situation where the pressure block 100 and the C-shaped steel 300 are suspended in the air, leaving the photovoltaic frame 400 to bear the load alone. Therefore, by setting the protruding strip 120 on the pressure block 100, the photovoltaic system's ability to resist high-intensity loads can be further enhanced, and its stability can be improved.

[0033] Furthermore, by providing a protruding strip 120 in the middle of the pressure block 100, deformation of the middle of the pressure block 100 can be prevented during the process of tightening the pressure block 100 and the connector 200, thereby improving the service life of the pressure block 100.

[0034] In one embodiment, the protrusion 120 is mounted on the strip opening 301, and the height of the protrusion 120 protruding from the first surface is higher than the height of the hook edge 110 protruding from the first surface, and the height difference is adapted to the height of the protrusion edge 410.

[0035] In one example, the ridge 120 extends along the length of the block body.

[0036] In this embodiment, the extension direction of the strip opening 301 of the C-shaped steel 300, or the direction parallel to the extension direction of the strip opening 301, is the length direction of the C-shaped steel 300 and the length direction of the connector 200. The pressure block 100 and the photovoltaic frame 400 are both perpendicular to the C-shaped steel 300 or perpendicular to the strip opening 301, and their length directions are either along the extension direction of the protruding edge 410 or parallel to the extension direction of the protruding edge 410.

[0037] The protruding strip 120 extends along the length of the pressure block body, meaning the length of the protruding strip 120 is the same as the length of the pressure block 100. The protruding strip 120 is mounted on the strip opening 301, meaning the protruding strip 120 is mounted against the purlin. To prevent the hook edge 110 from failing to firmly secure the protruding edge 410 of the photovoltaic frame 400 after the pressure block 100 is tightened, the height of the protruding strip 120 protruding from the first surface is higher than the height of the hook edge 110 protruding from the first surface, and the height difference is adapted to the height of the protruding edge 410. Typically, the height difference is slightly greater than the height of the protruding edge 410, so that when the hook edge 110 is pressed against the protruding edge 410, the protruding strip 120 still has elastic space to move towards the C-shaped steel 300.

[0038] In one embodiment, the cross-section of the protrusion 120 along the direction perpendicular to the hook edge 110 is trapezoidal, with the long side of the trapezoid close to the first surface.

[0039] The short side of the trapezoid and the C-shaped steel 300 structure have a wider distance between the edge of the short side and the hook edge 110 compared to the long side near the first surface, so that the hook edge 110 can be easily inserted into the groove of the convex edge 410 in the photovoltaic frame 400 to achieve quick assembly.

[0040] Furthermore, in order to obtain more force for the protrusion 120 in the pressure block 100, the side of the protrusion 120 closest to the first surface is the long side, that is, the contact area between the protrusion and the first surface is as large as possible. When the pressure block 100 is pressed, more force can be applied to the protrusion 120, so that the downward force of the pressure block 100 is greater and more evenly distributed.

[0041] In one embodiment, the width of the protrusion 120 is 2 / 5 to 3 / 5 of the width of the pressing block body. The width of the protrusion 120 can be as wide as possible to facilitate the hook edge 110 fitting within the protrusion edge 410. However, since the pressing block 100 is pressed between two adjacent photovoltaic frame 400s, the width of the pressing block 100 cannot be too wide; otherwise, it will affect the number of photovoltaic panels per unit area, thus affecting the power generation efficiency per unit area.

[0042] With a fixed width of the pressure block 100, the width of the protrusion 120 can be 2 / 5 to 3 / 5 of the width of the pressure block body, so as to exert a larger force on the fastening between it and the connector 200.

[0043] In one example, if the width of the block body is 10cm, the width of the ridge 120 can be 4cm, 5cm, or 6cm.

[0044] This application provides a connector 200 applied in a photovoltaic system. The photovoltaic system also includes a C-shaped steel 300, a pressure block 100, and a photovoltaic frame 400. The C-shaped steel 300 forms a strip opening 301. The photovoltaic frame 400 is mounted on the strip opening 301 and includes a protruding edge 410. The pressure block 100 is mounted on the strip opening 301 and presses against the protruding edge 410. The connector 200 includes a connecting plate 210 and at least two hook plates 220. The at least two hook plates 220 are respectively hinged to opposite sides of the connecting plate 210. The connecting plate 210 is located inside the strip opening 301, and the at least two hook plates 220 respectively hook onto the two side edges of the C-shaped steel 300. The pressure block 100 is fastened to the connector 200 to fasten the photovoltaic frame 400 and the C-shaped steel 300.

[0045] In one example, such as Figures 1 to 5 As shown, there are two hook plates 220, which are respectively set on opposite sides of the connecting plate 210.

[0046] The hook plate 220 is hinged to the connecting plate 210, so that when the pressure block 100 and the connector 200 are pressed, the hook plate 220 can be adjusted to a suitable angle. After the fastening is completed, the hook plate 220 is firmly hooked to the side edge of the C-shaped steel 300 and fits tightly with no room for movement, so as to enhance the fastening effect between the hook plate 220 and the side edge after fastening, thereby making the connection between the connector 200 and the C-shaped steel 300 stable and resistant to high loads.

[0047] In one embodiment, the width of the connecting plate 210 is 2 / 3 to 5 / 6 of the width of the strip opening 301; the hook angle of the hook plate 220 is 55-90°.

[0048] The connecting plate 210 is movably disposed within the strip opening 301, and its width is smaller than the width of the strip opening 301. However, the width of the connecting plate 210 cannot be too small, otherwise the angle between the hook plate 220 and the side edge will tend to be horizontal, which is not conducive to the compaction and fixation between the C-shaped steel 300 and the photovoltaic frame 400. In this embodiment, by limiting the width of the connecting plate 210 to 2 / 3-5 / 6 of the strip opening 301, such as 2 / 3, 7 / 10, or 5 / 6, it can be ensured that the hook plate 220 has a large upward force after hooking the side edge.

[0049] The hook angle of the hook plate 220 is 55-90°, preferably 60°-75°. The hook angle of the hook plate 220 is also adapted to the shape of the side edge. The wider the side edge, the larger its hook angle is, so as to completely hook the side edge.

[0050] In one embodiment, the length of the connecting plate 210 is 3 / 5 to 3 / 4 of the width of the pressure block body. Both the length of the connecting plate 210 and the width of the pressure block body are dimensions in a direction parallel to the extending direction of the strip opening 301. The length of the connecting plate 210 can be less than or greater than the width of the pressure block body. The length of the connecting plate 210 determines the length of the hook plate 220 that hooks onto the side edge of the C-shaped steel 300. A longer length results in a wider distribution of upward force on the C-shaped steel 300 and a stronger load-bearing capacity. However, the enhanced load-bearing capacity is limited. Therefore, the length of the connecting plate 210 is limited to 3 / 5 to 3 / 4 of the width of the pressure block body to avoid an excessively long connecting plate 210 increasing the weight of the photovoltaic bracket and wasting costs.
