Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to an integrated photovoltaic bracket. Background Art

[0002] Driven by the concept of new energy development, photovoltaic power generation projects are developing rapidly, with the number of photovoltaic power stations increasing year by year, and the number of photovoltaic power station piles is enormous. Photovoltaic brackets are the support system for photovoltaic modules in photovoltaic power generation systems. The brackets are fixed to the top of the photovoltaic power station pile foundation through a connecting structure at the bottom. The safety and economic efficiency of the connection between the brackets and the pile foundation have a significant impact on the entire photovoltaic power generation project.

[0003] Currently, traditional photovoltaic rack structures primarily consist of purlins, diagonal beams, columns, diagonal braces, and clamps. Purlins are fixed to the bracket's diagonal beams, and the photovoltaic panel assembly is connected to the purlins using bolts. The columns and diagonal braces are bolted to the diagonal beams at one end, while the diagonal braces are secured to the columns at the other end using clamps. Traditional photovoltaic rack installation typically involves pre-embedded steel pipe within the pile foundation, through which the brackets of the photovoltaic rack are bolted. After the brackets are secured, the clamps, diagonal beams, and diagonal braces are installed, completing the installation of the photovoltaic rack. Typically, four to five photovoltaic racks form the supporting structure for the photovoltaic panels. Purlins are then connected to the pre-installed diagonal beams using purlin brackets. After several purlins are installed on the diagonal beams, the panels are then placed atop the purlins. This installation method requires the installation of each supporting structure piece by piece, preventing the possibility of a complete hoisting system. Furthermore, each piece is bolted together, making the installation process slow and inefficient. Summary of the Invention

[0048] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

For example, they may refer to fixed or detachable connections, or integral connections; mechanical or electrical connections; direct connections or connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0050] In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," etc. used in the present invention to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0051] See also Figures 1 to 6It should be noted that the diagrams provided in this embodiment are merely schematic illustrations of the basic concept of the present invention. Therefore, the diagrams only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0052] The present invention provides an integrated photovoltaic bracket, such as Figures 1 to 5 As shown, the integrated photovoltaic bracket includes a grid 10 and a plurality of support columns 20, the grid 10 is fixedly arranged on the top of the support column 20, the plurality of support columns 20 are used to support the grid 10, the grid 10 is used to install photovoltaic panel components (not shown in the figure), and a crank fastening module 30 is provided on each support column 20, the crank fastening module 30 includes a sleeve 31 and a plurality of connecting rod assemblies 32 which are sleeved on the support column 10, wherein the sleeve 31 can slide along the support column 20, and the plurality of connecting rod assemblies 32 are evenly spaced along the circumferential direction of the sleeve 31, and each group of connecting rods The first ends of the components 32 are hinged to the sliding sleeves 31, and the first ends of each group of connecting rod components 32 are also hinged to the supporting column 20. When the sliding sleeves 31 slide along the supporting column 20 to the first position, the sliding sleeves 31 will drive the second ends of each group of connecting rod components 32 to expand with each other. When the sliding sleeves 31 slide along the supporting column 20 to the second position, the sliding sleeves 31 can drive the second ends of each group of connecting rod components 32 to retract with each other. Specifically, a positioning structure 21 is provided on the supporting column 20. The positioning structure 21 is used to position the second position of the sliding sleeve 31 to prevent the sliding sleeve 31 from sliding at the second position.

[0053] The beneficial effects of the integrated photovoltaic bracket of the present invention are as follows: when the integrated photovoltaic bracket is installed, the integrated photovoltaic bracket is hoisted as a whole, so that the bottoms of the multiple support columns 20 are hoisted and placed on the tops of the corresponding multiple pile foundations 200 (the sliding sleeve 31 is located at the first position of the support column before hoisting). After the multiple support columns 20 are in contact with the multiple pile foundations 200 in a one-to-one correspondence, the sliding sleeve 31 can be slid from the first position to the second position by sliding the sliding sleeve 31, so that the sliding sleeve 31 drives the multiple groups of connecting rods. The second ends of the components 32 are brought close together, so that the second ends of the multiple connecting rod assemblies 32 tightly embrace the pile foundation 200. At this time, the sleeve 31 is positioned by the positioning mechanism 21 provided on the support column 20, preventing the sleeve 31 from sliding in the direction close to the first position, thereby limiting the second ends of the connecting rod assemblies 32 from expanding outward, so that the second ends of the multiple connecting rod assemblies 32 firmly embrace the pile foundation 200, thereby achieving the fixation of the support column 20 and the pile foundation 200 through the crank fastening module 30. Therefore, compared with the prior art, the integrated photovoltaic bracket of the present invention can realize the rapid installation and removal of the bracket, and the operation is simple and convenient. During installation, there is no need to screw the brackets one by one at the construction site, which greatly reduces the amount of on-site construction work and greatly improves construction efficiency. In addition, the crank fastening module used in the present invention does not require any modification to the pile foundation, and it is also relatively convenient to modify and reconstruct the bracket of the completed project.

[0054] Furthermore, in order to improve the stability of the support column 20 on the grid 10, as shown in FIG. Figure 1 and Figure 3 As shown, in this embodiment, each support column 20 is further provided with a plurality of diagonal braces 22, which are evenly spaced along the circumference of the support column 20. One end of each diagonal brace 22 is connected to the bottom of the support column 20, and the other end of each diagonal brace 22 extends upward at an angle and is connected to the grid 10. Specifically, in this embodiment, there are four diagonal braces 22, each of which is bolted to the bottom of the support column 22 at one end, and bolted to the grid 10 at the other end, resulting in a simple structure and convenient assembly and disassembly.

[0055] Furthermore, if Figure 2As shown, in this embodiment, the connecting rod assembly 32 includes a push rod 321 and an L-shaped crank rod 322. Specifically, the L-shaped crank rod 322 includes a first connecting rod 3221 and a second connecting rod 3222, wherein the length of the first connecting rod 3221 is less than the length of the second connecting rod 3222, the first end of the first connecting rod 3221 is hinged to the support column 20, and the second end of the first connecting rod 3221 intersects with the first end of the second connecting rod 3222, the first end of the push rod 321 is hinged to the sliding sleeve 31, and the second end of the push rod 321 is hinged to the intersection of the first connecting rod 3221 and the second connecting rod 3222, and the second end of the second connecting rod 3222 forms the second end of the connecting rod assembly 32. When in use, as shown in FIG. Figure 2 and Figure 4 As shown, when the sliding sleeve 31 is in the first position of the supporting column 20, the sliding sleeve 31 pulls the first end of the push rod 321 in each group of connecting rod assemblies 32, and the push rod 321 pulls the L-shaped crank rod 322 so that the second end of the second connecting rod 3222 of the L-shaped crank rod 322 is expanded outward, so that the second end of each group of connecting rod assemblies 32 is in an outward expanded state (as shown in FIG. Figure 2 When the cam 32 is in the upright position, the second end of the second link 3222 is moved to the left and right sides of the cam 32 and the cam 32 is moved to the right and left sides of the cam 32. When the cam 32 is in the upright position, the second end of the second link 3222 is moved to the right and left sides of the cam 32 and the cam 32 is moved to the right and left sides of the cam 32.

[0056] The crank fastening module 30 of the present invention can be applied not only to large grid structures, such as Figure 6 As shown, this is also applicable to the structural modification of photovoltaic brackets commonly found in existing projects. In some existing projects, the pile foundation has been completed and buried in the soil. If the upper bracket is damaged for some reason and needs to be repaired, the crank fastening module 30 of the present invention can be used to structurally modify the existing bracket. Without changing the pile foundation structure, the bracket structure can be completed in the factory and directly hoisted to the construction site, greatly shortening the on-site construction time.

[0057] Furthermore, in order to improve the degree of clamping and fixing of the second end of the connecting rod assembly 32, that is, the second end of the second connecting rod 3222 to the pile foundation 200, it is preferred that Figure 2As shown, in this embodiment, a curved pressure plate 323 is fixed to the second end of each second connecting rod 3222. Due to this structural design, when the second end of each second connecting rod 3222 in each connecting rod assembly 32 is clamped to the pile foundation 200, the curved pressure plate 323 can closely fit the curved surface of the pile foundation 200, thereby increasing the contact area between the second connecting rod 3222 and the pile foundation 200, and thus significantly improving the clamping force of the second connecting rod 3222 on the pile foundation 200. Specifically, in this embodiment, four connecting rod assemblies 32 are provided.

[0058] Furthermore, if Figure 2 As shown, in this embodiment, a plurality of first ear plates 311 are provided on the sliding sleeve 31, and the first end of the push rod 321 is hinged to the first ear plate 311 through a pin shaft 324, and the second end of the push rod 321 is also hinged to the intersection of the first connecting rod 3221 and the second connecting rod 3222 through the pin shaft 324; specifically, a seat plate 23 is provided at the bottom of the support column 20, and a plurality of second ear plates 231 are fixed on the seat plate 23 at evenly spaced intervals along the circumferential direction of the support column 20, and the first end of the first connecting rod 3221 is hinged to the second ear plate 231 through a pin shaft 324.

[0059] Furthermore, if Figure 4 and Figure 5 As shown, in this embodiment, the positioning mechanism 21 includes a spring sleeve 211 fixedly arranged in the support column 20, and the axial direction of the spring sleeve 211 is perpendicular to the axial direction of the support column 20, that is, the spring sleeve 211 is transversely arranged inside the support column 20, and a spring 212 is arranged in the spring sleeve 211, and a receiving groove 2111 is provided at both the left and right ends of the spring sleeve 211, and a positioning protrusion 213 is provided in each of the left and right receiving grooves 2111, and the positioning protrusion 213 is sandwiched between the end of the spring 212 and the inner wall of the support column 20, and correspondingly, an extrusion notch 201 is provided at the position corresponding to the two positioning protrusions 213 on the support column 20, and the positioning protrusion 213 protrudes outward from the corresponding extrusion notch 201. With such a configuration, when in use, when the sliding sleeve 31 is in the first position (such as Figure 2 As shown), that is, when the second ends of each connecting rod assembly 32 are in an outwardly extended state, the sliding sleeve 31 is located above the positioning protrusion 213. When the support column 20 is fixedly installed on the pile foundation 200, so that the second end of the second connecting rod 3222 of the L-shaped crank rod 322 is tightly holding the pile foundation 200, the left and right positioning protrusions 213 are pressed, so that the positioning protrusions 213 compress the springs 212 inwardly, thereby compressing the positioning protrusions 213 into the interior of the support column 20. At the same time, the sliding sleeve 31 is pulled downward to slide downward. When the sliding sleeve 31 is pulled to the second position below the positioning protrusion 213 (as shown in FIG. Figure 4As shown, the second end of the second connecting rod 3222 of the L-shaped crank rod 322 tightly embraces the pile foundation 200. At this time, the positioning protrusion 213 is reset outward based on the reset action of the spring 212. The spring 212 pops the positioning protrusion 213 outward and resets it. The positioning protrusion 213 again protrudes outward from the outer wall of the support column 20 through the extrusion notch 201. As a result, the positioning protrusion 213 blocks the upper edge of the sliding sleeve 31, restricting the upward movement of the sliding sleeve 31, and achieving a firm hold of the second end of the second connecting rod 3222 against the pile foundation 200. The structure is simple and the operation is convenient. It avoids the operation of fastening multiple parts with bolts when installing a photovoltaic bracket on a pile foundation in the prior art, thereby greatly improving the installation efficiency of the photovoltaic bracket.

[0060] Furthermore, if Figure 4 As shown, in this embodiment, a pull ring 310 is provided on the sliding sleeve 31. When the sliding sleeve 31 is pulled up and down along the supporting column 20, a steel rod or steel wire rope can be passed through the pull ring 310 to pull the sliding sleeve 31 up and down through the steel rod or steel wire rope, which is more labor-saving.

[0061] Furthermore, in order to improve the convenience of switching the sliding sleeve 31 from the first position to the second position, preferably, as Figure 5 As shown, in this embodiment, the positioning protrusion 213 includes an upper positioning surface 2131 and a lower positioning surface 2132, wherein the angle between the upper positioning surface 2131 and the vertical direction is smaller than the angle between the lower positioning surface 2132 and the vertical direction. With this arrangement, when the sliding sleeve 31 is pulled downward, since the angle between the upper positioning surface 2131 of the positioning protrusion 213 and the vertical direction is smaller, the sliding sleeve 31 will exert an inner squeezing force on the upper positioning surface 2131 of the positioning protrusion 2131 as the sliding sleeve 31 slides downward. This squeezing force will squeeze the positioning protrusion 213 into the support column 20. As the sliding sleeve 31 continues to move downward, the sliding sleeve 31 will continuously squeeze the positioning protrusion 213 into the support column 20. Therefore, when the sliding sleeve 31 is pulled downward from the first position to the second position, it is no longer necessary to press the positioning protrusion 213 first. The sliding sleeve 31 can be directly pulled, making the operation simpler and more convenient.

[0062] Furthermore, in order to improve the convenience of connecting the grid 10 and the support column 20, as shown in FIG. Figure 2 As shown, in this embodiment, a connecting plate 101 is welded and fixed to the grid 10. The connecting plate 101 is connected to the top of the support column by bolts. This facilitates the subsequent disassembly of the grid 10. Specifically, the connecting plate 101 is U-shaped, and the top of the support column 20 is embedded in the groove of the U-shaped connecting plate 101.

[0063] Specifically, such as Figure 1As shown, in this embodiment, the grid 10 is welded and spliced together from multiple transverse steel bars, multiple vertical steel bars, and multiple diagonal steel bars. Fixing plates are welded at the intersections of the transverse, vertical, and diagonal steel bars, and the connecting plates 101 are welded and fixed to the fixing plates. Specifically, the diagonal braces 22 are also bolted to the fixing plates 102 on the grid 10.

[0064] In summary, the integrated photovoltaic bracket of the present invention enables rapid installation and removal of the bracket, and is simple and convenient to operate. During installation, there is no need to screw each component individually at the construction site, which greatly reduces the amount of on-site construction work and greatly improves construction efficiency. Furthermore, the crank fastening module used in the present invention does not require any modification to the pile foundation, making it relatively convenient to modify and reconstruct the bracket of a completed project. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
