[0033] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0034] Example 1
[0035] like Figures 1 to 4 As shown, this embodiment proposes a purlin, which includes a fixed section 1-1 and a wind-resistant section 1-2, wherein the wind-resistant section 1-2 is located between the two fixed sections 1-1. The fixed section 1-1 is used to fix it to the photovoltaic module, and the wind-resistant section 1-2 is used to fix it to the main shaft of the mounting bracket and enhance the bending resistance of the purlin when bearing the load of the photovoltaic module.
[0036] Specifically, in this embodiment, the purlin has a fixed section 1-1 at one end, a wind-resistant section 1-2 in the middle, and a fixed section 1-1 at the other end. The wind-resistant section 1-2 is located between the two fixed sections 1-1, and the two fixed sections 1-1 and the wind-resistant section 1-2 can be integrally formed. The first main body part 1-1-2 of the fixed section 1-1 and the second main body part 1-2-2 of the wind-resistant section 1-2 have the same longitudinal cross-section, which is generally in the shape of a U. The first main body part 1-1-2 of the fixed section 1-1 has first bending parts 1-1-1 formed by bending the top parts on both sides of the first main body part 1-1-2 outward, and the first bending parts 1-1-1 are perpendicular to the side walls of the first main body part 1-1-2, which is the same as the traditional purlin structure at both ends. The second main body part 1-2-2 of the wind-resistant section 1-2 has second bending parts 1-2-1 formed by bending the top parts on both sides of the second main body part 1-2-2 outward and parallel to the side walls of the second main body part 1-2-2, that is, the top parts on both sides of the wind-resistant section 1-2 are bent outward by 180°, so that the second bending parts 1-2-1 are parallel to the side walls of the second main body part 1-2-2.
[0037] In actual production, the fixed section 1-1 and the wind-resistant section 1-2 can be integrally formed, and then the top parts on both sides of the purlin are bent outward by 90° as a whole. Then, the part between the fixed section 1-1 and the wind-resistant section 1-2 is cut. After cutting, the top parts on both sides of the second main body part 1-2-2 of the wind-resistant section 1-2 are further bent downward by 90° until they are parallel to the side walls of the second main body part 1-2-2 of the wind-resistant section 1-2.
[0038] This embodiment further bends the flange of the middle section outward until it is parallel to the side walls of the purlin based on the traditional purlin structure in the shape of a U, thereby improving the bending resistance of the purlin when bearing the load of the photovoltaic module.
[0039] Embodiment 2
[0040] As shown in Figure 5 , this embodiment proposes a reinforcing assembly based on embodiment 1. The reinforcing assembly includes a purlin 1 and a reinforcing device 2, wherein the reinforcing device 2 is arranged on the fixed section 1-1 at both ends of the purlin 1. The specific structure of the purlin 1 can refer to the content described in embodiment 1, and this embodiment will not be described again.
[0041] The reinforcing device 2 can be used with the purlin 1 proposed in embodiment 1 to improve the mechanical load capacity of the mounting bracket for installing the photovoltaic module. As shown in Figure 6 , the reinforcing device 2 includes:
[0042] a clamp 2-1 located between the photovoltaic module 3 and the purlin 1, used for clamping a steel cable 2-2;
[0043] a fixing part 2-3 used for fixing the clamp 2-1 on the fixed section 1-1 of the purlin 1.
[0044] Specifically, in the present embodiment, the steel cable 2-2 is arranged in the clamp 2-1, and the clamp 2-1 clamps the steel cable 2-2. Then, the clamp 2-1 is fixed on the fixed section 1-1 of the purlin 1 by the fixing member 2-3. A cavity is formed in the clamp 2-1, as shown in the figure. The cavity penetrates through the two opposite sides of the clamp 2-1, so that the steel cable 2-2 can be arranged in the cavity from one side of the clamp 2-1, and then be arranged out from the other side of the clamp 2-1. A protrusion 2-1-1 is arranged on the inner wall of the cavity, which can press the steel cable 2-2 when the steel cable 2-2 is arranged in the cavity, so as to increase the friction between the steel cable 2-2 and the inner wall of the cavity, and increase the clamping force of the clamp 2-1 on the steel cable 2-2. The number and arrangement density of the protrusions 2-1-1 can be adaptively set according to the actual direction and size of the cavity, and the present embodiment is not specially limited. Figure 7
[0045] The fixing member 2-3 can fix the clamp 2-1 on the fixed section 1-1 of the purlin 1, so that the clamp 2-1 is located between the photovoltaic module 3 and the purlin 1. Preferably, the fixing manner is detachable installation, so as to facilitate the later maintenance. Since the steel cable 2-2 is arranged in the clamp 2-1, if the arrangement direction of the steel cable 2-2 is consistent with the length direction of the purlin 1, it is not conducive to the “threading” of the steel cable 2-2 from one clamp to another clamp. Therefore, when the clamp 2-1 is fixed on the purlin 1, the length direction of the cavity (the arrangement direction of the steel cable 2-2) needs to be at a certain angle with the length direction of the purlin 1, and preferably at a perpendicular angle.
[0046] The present embodiment improves the front mechanical load of the installation support by adding the steel cable 2-2 and the clamp 2-1 clamping the steel cable 2-2. The clamp 2-1 and the protrusions 2-1-1 arranged in the clamp 2-1 can increase the fastening of the steel cable 2-2. In addition, the clamp 2-1 can also constrain the bending deformation of the contact surface of the purlin 1 and the bending deformation of the vertical surface of the purlin 1 towards the main shaft 4 when the photovoltaic module 3 bears the load. Furthermore, compared with the existing steel cable 2-2 reinforcement method, the clamp 2-1 can make the distance between the steel cable 2-2 and the back of the photovoltaic module 3 smaller, and also increase the contact width of the frame of the photovoltaic module 3 and the purlin 1, so as to avoid the uneven stress caused by the right-angle contact of the purlin 1 and the frame of the photovoltaic module 3 when the front load is applied.
[0047] In some optional embodiments, the clamp 2-1 includes an upper clamping plate 2-1-2 and a lower clamping plate 2-1-3, and the lower clamping plate 2-1-3 is buckled on the upper clamping plate 2-1-2 to form the clamp 2-1.
[0048] Specifically, the upper clamping plate 2-1-2 and the lower clamping plate 2-1-3 can be plate-shaped structures with a certain thickness. A lower cavity 2-1-4 is formed on the upper surface of the lower clamping plate 2-1-3, and an upper cavity (not shown in the figure) is formed on the lower surface of the upper clamping plate 2-1-2. When the upper clamping plate 2-1-2 is buckled on the lower clamping plate 2-1-3, the upper cavity and the lower cavity 2-1-4 form a cavity.
[0049] In some alternative embodiments, the cavity has at least one bending angle.
[0050] Specifically, in the present embodiment, the cavity can be straight, but the straight cavity will reduce the friction of the steel cable 2-2. Therefore, in the present embodiment, the cavity is designed to be a broken line, that is, the cavity has at least one bending angle, which can be an L-shaped, Z-shaped or N-shaped bending shape. However, since the steel cable 2-2 needs to be arranged in multiple reinforcing devices 2 during actual installation of the reinforcing device 2, the steel cable 2-2 also needs to have a certain smoothness inside the reinforcing device 2. Therefore, the bending angle of the cavity should not be too many, one or two is enough, and the angle of the bending angle should not be too small, an obtuse angle is more appropriate. In addition, in order to make the steel cable 2-2 more fit the inner wall of the cavity, the bending angle can be designed as a circular arc.
[0051] In some alternative embodiments, the protrusion 2-1-1 is located at the bottom of the lower cavity 2-1-4 and / or the top of the upper cavity.
[0052] Specifically, in the present embodiment, the protrusion 2-1-1 of the inner wall of the cavity can be arranged in various positions. For example, it can be arranged on the side wall of the cavity, the top of the cavity or the bottom of the cavity, etc. In order to ensure that the protrusion 2-1-1 can extrude the steel cable 2-2 while the upper clamping plate 2-1-2 and the lower clamping plate 2-1-3 clamp the steel cable 2-2, the protrusion 2-1-1 is arranged at the top or bottom of the cavity, or the top and bottom of the cavity are both arranged with the protrusion 2-1-1.
[0053] More specifically, the embodiment provides three choices of the position of the protrusion 2-1-1. First, the protrusion 2-1-1 is located at the bottom of the lower cavity 2-1-4. Second, the protrusion 2-1-1 is located at the top of the upper cavity. Third, the protrusion 2-1-1 is located at both the bottom of the lower cavity 2-1-4 and the top of the upper cavity. For the first position, in order to make the upper clamp plate 2-1-2 and the lower clamp plate 2-1-3 clamp the steel cable 2-2 more firmly, the distance between the protrusion 2-1-1 at the bottom of the lower cavity 2-1-4 and the top of the upper cavity should be less than the diameter of the steel cable 2-2 when the upper clamp plate 2-1-2 is buckled on the lower clamp plate 2-1-3. Similarly, for the second position, the distance between the protrusion 2-1-1 at the top of the upper cavity and the bottom of the lower cavity 2-1-4 should also be less than the diameter of the steel cable 2-2 when the upper clamp plate 2-1-2 is buckled on the lower clamp plate 2-1-3. For the third position, the distance between the protrusion 2-1-1 at the top of the upper cavity and the protrusion 2-1-1 at the bottom of the lower cavity 2-1-4 should be less than the diameter of the steel cable 2-2 when the upper clamp plate 2-1-2 is buckled on the lower clamp plate 2-1-3.
[0054] In some optional embodiments, the shape of the protrusion 2-1-1 can be semicircular or long strip-shaped. The semicircular protrusion 2-1-1 can increase the pressure between the protrusion 2-1-1 and the steel cable 2-2, and the long strip-shaped protrusion 2-1-1 can increase the friction area between the protrusion 2-1-1 and the steel cable 2-2. The specific shape can be selected according to the actual situation.
[0055] In some optional embodiments, the fixing member 2-3 fixes the clamp 2-1 between the photovoltaic module 3 and the purlin 1 through the mounting hole formed on the clamp 2-1.
[0056] Specifically, the upper clamp plate 2-1-2 is provided with an upper mounting hole 2-1-5, and the lower clamp plate 2-1-3 is provided with a lower mounting hole 2-1-6 corresponding to the upper mounting hole 2-1-5. The fixing member 2-3 fixes and connects the clamp 2-1 and the fixed section 1-1 of the purlin 1 through the upper mounting hole 2-1-5 and the lower mounting hole 2-1-6. Generally, the number of the upper mounting hole 2-1-5 and the lower mounting hole 2-1-6 is even, and they are axially symmetrical or centrally symmetrical to ensure the stability of the installation.
[0057] In some optional embodiments, the fixing member 2-3 includes a nut 2-3-3, a gasket 2-3-2 and a bolt 2-3-1. The fixing of the clamp 2-1 and the fixed section 1-1 of the purlin 1 is achieved by the threaded connection of the bolt 2-3-1 and the nut 2-3-3.
[0058] Specifically, in order to fix the clamp 2-1 and the purlin 1, mounting holes are also needed to be opened on the first bending part 1-1-1 of the fixed section 1-1 of the photovoltaic module 3 frame and the purlin 1, and the positions of the mounting holes on the first bending part 1-1-1 of the photovoltaic module 3 frame and the purlin 1 fixed section 1-1 need to correspond to the upper mounting hole 2-1-5 of the upper clamp plate 2-1-2 and the lower mounting hole 2-1-6 of the lower clamp plate 2-1-3. Thus, the bolt 2-3-1 can pass through the purlin 1 through the mounting hole on the first bending part 1-1-1 of the fixed section 1-1 of the purlin 1, then pass through the lower mounting hole 2-1-6 and the upper mounting hole 2-1-5, and finally pass out through the mounting hole on the photovoltaic module 3 frame and be screwed with the nut 2-3-3 located at the mounting hole on the photovoltaic module 3 frame. At the same time, the head of the bolt 2-3-1 and the first bending part 1-1-1 of the fixed section 1-1 of the purlin 1 are provided with a gasket 2-3-2 between the nut 2-3-3 and the photovoltaic module 3 frame, so as to increase the contact area and prevent loosening.
[0059] Embodiment 3
[0060] As shown in Figure 5 and Figure 8 , the present embodiment proposes a mounting bracket for mounting a photovoltaic module 3. The mounting bracket comprises a main shaft 4, a purlin 1 and a reinforcing device 2, wherein the specific structure of the purlin 1 and the reinforcing device 2 can refer to the content described in Embodiment 1 and Embodiment 2, and the present embodiment will not be described again. The number of purlins 1 is multiple, which can be determined by the number of photovoltaic modules 3 to be installed. The plurality of purlins 1 are arranged at intervals on the main shaft 4 and can be fixedly connected with the main shaft 4 through the U-shaped bolt 5, and the length direction of the plurality of purlins 1 is perpendicular to the length direction of the main shaft 4. The two ends of each purlin 1 are provided with a reinforcing device 2. The steel cable 2-2 passes through the cavities of the reinforcing devices 2 on the same side of the main shaft 4 in sequence, as shown in Figure 5 .
[0061] In the process of assembling the mounting bracket, first, the purlin 1 is placed on the main shaft 4 in the center, and the purlin pressing plate is placed from above, then the U-shaped bolt 5 is passed through from below the main shaft, and the nut is pre-tightened, so as to pre-assemble the purlin 1 on the main shaft 4. Before the reinforcing device 2 is installed on the purlin 1, first, the photovoltaic module 3 is placed, and the clamp 2-1 is placed between the frame of the photovoltaic module 3 and the purlin 1. Then, the nut 2-3-3, the gasket 2-3-2 and the bolt 2-3-1 are pre-assembled, and are kept in a state of not being tightened. The photovoltaic module 3 and the upper clamp 2-1-2 are lifted by a distance, so as to ensure that the steel cable 2-2 can pass through the cavity in the clamp 2-1. After the steel cable 2-2 is passed in, the bolt 2-3-1 on one side and the nut 2-3-3 are tightened for pre-tightening, then the steel cable 2-2 is sequentially passed through the clamps 2-1 on the same side on the remaining purlins 1, and the steel cable 2-2 is pre-tightened at a distance of every photovoltaic module 3, and finally all the bolts 2-3-1 and the nuts 2-3-3 are tightened. In the embodiment, the bolt 2-3-1 and the nut 2-3-3 can be the fasteners for the frame of the photovoltaic module 3 and the purlin 1, and no additional fasteners are needed.
[0062] Obviously, various modifications and changes can be made to the present application by those skilled in the art without departing from the spirit and scope of the application. Accordingly, it is intended that the present application embrace all such modifications and changes as fall within the scope of the claims and their equivalents.
