Description

Technical Field

[0001] The invention belongs to the field of solar photovoltaic power generation, and specifically relates to the field of basalt fiber photovoltaic brackets, and in particular to an energy-consuming basalt fiber photovoltaic bracket that is not connected by opening holes. Background Art

[0002] Photovoltaic brackets are key components in solar photovoltaic power generation systems. Although significant progress has been made in design and application, there are still some common defects and problems. As a key component for supporting and fixing photovoltaic modules, the performance and reliability of photovoltaic brackets have an important impact on the efficiency and life of the entire system. At present, the photovoltaic brackets widely used in the market are mostly made of metal materials, such as carbon steel, stainless steel and aluminum alloy. However, these metal materials have some defects in practical applications, including easy corrosion, heavy weight, thermal expansion, and high cost and maintenance requirements. Especially in humid, salt spray or industrially polluted environments, the corrosion problem of metal brackets is particularly prominent, which seriously affects the mechanical strength and service life of the brackets. In addition, the weight of the metal bracket increases the difficulty of transportation and installation, and the deformation caused by thermal expansion will also affect the stability and safety of photovoltaic modules. In order to overcome the above problems, more and more photovoltaic brackets are currently using basalt fiber as a material, but most of them are connected in an open-hole form, which destroys its integrity and causes the basalt fiber material to fail to fully exert its performance.

[0003] Basalt fiber is a continuous fiber drawn from a large amount of basalt minerals after high-temperature melting. These fiber filaments are interwoven or arranged to form a material with a certain shape and function. Basalt fiber has many excellent properties: low density and high specific strength, electrical insulation, and UV resistance. Therefore, it has been widely used in many fields; its good integrity enables basalt fiber materials to effectively transmit stress. When basalt fiber is subjected to external force, the stress can be evenly distributed throughout the fiber structure instead of being concentrated in a local area, thereby giving full play to the mechanical properties of the fiber and improving the bearing capacity of the material. However, the existing basalt fiber photovoltaic bracket is usually fixedly installed by opening holes; because the opening of basalt fiber materials will lead to the destruction of the continuity of the material structure, the stress is easily concentrated at the edge of the hole when it is subjected to force, which makes the material more prone to cracks and fractures, thereby reducing the mechanical properties of the material such as tensile strength and bending strength. Opening holes will increase the contact area between the material and the external environment, making the material more susceptible to erosion by factors such as ultraviolet rays and oxygen, accelerating the aging process of the material, and reducing the service life of the material.

[0004] In addition, due to the unique geographical and climatic conditions in some areas, the impact of wind load on photovoltaic brackets is particularly significant. Therefore, the importance of photovoltaic brackets in resisting wind loads cannot be ignored. From a mechanical point of view, wind loads will generate greater pressure or suction on photovoltaic brackets. When wind blows over photovoltaic modules and brackets, wind pressure will be generated on their surfaces. For photovoltaic brackets with fixed inclination angles, wind may blow from different directions, generating lateral forces; this lateral force will cause the bracket to bend and deform. If the wind load is too large, it may cause the rods of the bracket to yield or become unstable. From the perspective of stability, wind loads will affect the overall stability of photovoltaic brackets. Under the action of strong winds, photovoltaic brackets may slip, overturn, and other problems; especially for some photovoltaic brackets installed at higher positions, their foundations may be relatively weak, and the bracket as a whole may slide or overturn, thereby damaging the photovoltaic modules.

[0005] It can be seen that the existing basalt fiber photovoltaic bracket has poor mechanical properties and stability due to its installation and fixation in the form of open holes. Summary of the invention

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail in the following specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0031] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example As mentioned in the background technology, the existing basalt fiber photovoltaic bracket is usually fixedly installed by opening holes; because the opening of the basalt fiber material will cause the continuity of the material structure to be destroyed, the stress is easily concentrated at the edge of the hole when it is subjected to force, which makes the material more prone to cracks and fractures, thereby reducing the mechanical properties of the material such as tensile strength and bending strength. Opening holes will increase the contact area between the material and the external environment, making the material more susceptible to erosion by factors such as ultraviolet rays and oxygen, accelerating the aging process of the material, and reducing the service life of the material. In addition, due to the unique geographical and climatic conditions in some areas, the impact of wind load on photovoltaic brackets is particularly significant. Therefore, the importance of photovoltaic brackets in resisting wind loads cannot be ignored. From a mechanical point of view, wind loads will generate greater pressure or suction on photovoltaic brackets. When the wind blows through photovoltaic modules and brackets, wind pressure will be generated on their surfaces. For photovoltaic brackets with fixed inclination angles, the wind may blow from different directions, generating lateral forces; this lateral force will cause the bracket to bend and deform. If the wind load is too large, it may cause the rods of the bracket to yield and become unstable. From the perspective of stability, wind loads will affect the overall stability of photovoltaic brackets. Under the influence of strong winds, photovoltaic brackets may slip, overturn, and other problems; especially for some photovoltaic brackets installed at higher positions, their foundations may be relatively weak, and the entire bracket may slide or overturn, thereby damaging the photovoltaic modules.

[0035] In order to solve the above problems, the present invention provides an energy-consuming basalt fiber photovoltaic bracket with non-perforated connection. The bracket adopts a non-perforated connection method on all basalt fiber components, thereby ensuring that the performance of the basalt fiber material is optimal. At the same time, multiple groups of energy-consuming connectors are arranged at important connections, so that the overall structure has energy-consuming capabilities, thereby improving the stability and reliability of the overall bracket.

[0036] The present invention is further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1 As shown, this embodiment provides an energy-consuming basalt fiber photovoltaic bracket without opening and connection, and the specific structure and connection method are as follows: The support is mainly composed of a column 8 and a plurality of energy-consuming connecting parts arranged on the column 8.

[0037] like Figure 5 and Figure 6 As shown, in this embodiment, the energy-absorbing connector is the core part of the bracket, including a buckle 14; the buckle 14 is connected to the column 8, one end of the buckle 14 is self-fastened by bolts, and the other end is connected to the embedded connecting steel plate 13 fixed on the column 8 by bolts, and an energy-absorbing component is provided.

[0038] The energy-absorbing connecting piece includes two structures: a first energy-absorbing connecting structure 5 and a second energy-absorbing connecting structure 7 ; wherein the first energy-absorbing connecting structure 5 and the second energy-absorbing connecting structure 7 both include a buckle 14 and a pre-buried connecting steel plate 13 .

[0039] like Figure 5 As shown, the first energy dissipation connection structure 5 adopts a linear embedded connection steel plate 13, as shown in FIG. Figure 6 As shown, the second energy dissipation connection structure 7 adopts a bent pre-buried connection steel plate 13; these two structures are respectively suitable for different connection requirements; Figure 2 and Figure 3 As shown, a basalt fiber rod 12 is inserted into the buckle 14 of the first energy dissipation connection structure 5; the basalt fiber rod 12 is located in the middle part of the basalt fiber purlin 11, and can provide vertical support for the basalt fiber purlin 11; a diagonal brace 6 is inserted into the buckle 14 of the second energy dissipation connection structure 7; the diagonal brace 6 is located at both ends of the basalt fiber purlin 11, and can provide vertical support for the basalt fiber purlin 11.

[0040] A basalt fiber support structure is inserted in the middle of the buckle 14, and the basalt fiber support structure includes a diagonal brace 6 and a basalt fiber rod 12; the basalt fiber support structure is connected to the basalt fiber purlin 11 through a support structure connector, and can provide diagonal support force and vertical support force for the basalt fiber purlin 11; this design improves the overall stability and bearing capacity of the bracket.

[0041] like Figure 4 As shown, the supporting structure connector includes a connected prefabricated steel plate 3 and a sleeve connector 4, and the basalt fiber purlin 11 is inserted into the prefabricated steel plate 3 and clamped and fixed by the sleeve connector 4 and bolts; In this embodiment, one end of the double-hook rigid spring 16 is hooked on the embedded connecting steel plate 13 of the column 8 ; and the other end is hooked on the prefabricated steel plate 3 .

[0042] Another example Figure 5 and Figure 6 As shown, in this embodiment, the energy dissipation component consumes part of the energy generated by the external load through friction, thereby enhancing the energy dissipation capacity and seismic resistance of the bracket. Specifically, the energy dissipation component includes two aluminum friction plates 17, which are clamped between the other ends of the buckle 14 and fixed to the embedded connecting steel plate 13 by bolts; the basalt fiber support structure is connected by the energy dissipation component with aluminum friction plates 17. Before the external load overcomes the critical friction force, the node behaves as a "rigid connection node"; when the external load overcomes the critical friction force, the friction node slides relatively, consumes part of the energy, and at the same time limits the size of the external load transmitted to the rod, avoiding the rod from falling off and cracking. At this time, the node behaves as a "flexible connection node", which can absorb and disperse part of the energy brought by the wind load, thereby ensuring the stability of the structure.

[0043] like Figure 8 As shown, in order to reliably connect the photovoltaic panel 2 to the bracket, a fastening connector is used; a basalt fiber purlin 11 and a basalt fiber connecting block 1 are inserted inside the fastening connector; Fig. 9 As shown, the basalt fiber connection block 1 adopts a C-shaped cross-section structure, one end of which is connected to the photovoltaic panel 2 by bolts, and the other end is inserted into the fastening connector. In this embodiment, the fastening connector is composed of a first steel connection plate 9 and a second steel connection plate 10 of the same structure. The first steel connection plate 9 and the second steel connection plate 10 both adopt a connection block structure with a C-shaped cross-section; they are respectively located on both sides of the basalt fiber purlin 11 and the basalt fiber connection block 1, and are clamped and fixed by bolts; one end of the basalt fiber connection block 1 and the basalt fiber purlin 11 are firmly clamped and fixed between the first steel connection plate 9 and the second steel connection plate 10.

[0044] like Figure 4 and Figure 7 As shown, the diagonal brace 6 includes a basalt fiber sleeve 15 and a double-hook rigid spring 16 inserted into the basalt fiber sleeve 15, one end of the double-hook rigid spring 16 is connected to the embedded connecting steel plate 13 of the column 8, and the other end is connected to the prefabricated steel plate 3; this design enables the diagonal brace 6 to produce elastic deformation when subjected to external force, thereby consuming energy and enhancing the seismic performance of the bracket.

[0045] It can be seen that in this embodiment, the traditional diagonal brace is changed to a rigid spring connection. The rigid spring has a high rigidity and can keep its shape unchanged or change very little when subjected to external force; this rigidity property enables it to provide stable support force under wind load and prevent the structure from excessive displacement or deformation. Although the rigid springs have a high rigidity, they can still absorb and disperse part of the energy brought by the wind load; through appropriate pre-compression or pre-stretching, the rigid springs can produce a small deformation under the action of wind load, thereby absorbing part of the kinetic energy to ensure that the performance of the basalt fiber material is optimal, while making the structure as a whole have energy dissipation capacity.

[0046] Here, according to different use environments, wind loads of different sizes and earthquake loads, the number of double-hook rigid springs 16 can be increased or decreased to achieve optimal performance and the best economic solution.

[0047] like Figure 3 As shown, in this embodiment, the column 8 adopts a cylindrical concrete foundation structure, and the embedded connecting steel plate 13 is fixed in the column 8 by welding steel bars. This design improves the bearing capacity and stability of the column 8 and provides a reliable supporting foundation for the entire bracket.

[0048] It should be noted that: In the whole structural system, the column 8 is a cylindrical concrete foundation with a concrete strength of C40. The concrete foundation is to fix the bracket body on a concrete column or pile, and its advantages are stable structure and high bearing capacity. The concrete foundation is formed by welding six pre-buried connecting steel plates 13 to the steel bars and then pouring concrete. The pre-buried connecting steel plates 13 and two aluminum friction plates 17 and a "J"-shaped buckle 14 are connected by bolts. The first energy-absorbing connecting structure 5 for connecting the vertical support and the second energy-absorbing connecting structure 7 for connecting the oblique support are connected by two pre-buried connecting steel plates 13 and a double-hook rigid spring 16 using a spring port hook, and the basalt fiber rod 12 is passed through the first energy-absorbing connecting structure 5 for connecting the vertical support. The oblique brace 6 composed of a basalt fiber sleeve 15 and a double-hook rigid spring 16 passes through the second energy-absorbing connecting structure 7 for connecting the oblique support, and is connected by bolts to ensure that the rod is firmly connected to the column 8. The basalt fiber purlin 11 passes through the rectangular prefabricated steel plate 3 and the sleeve connector 4, and is connected to the diagonal brace 6 and the basalt fiber rod 12 by bolts, and the spring port at the other end of the double hook rigid spring 16 is connected to the prefabricated steel plate 3 to ensure that the spring has sufficient tensile and compressive resistance. The basalt fiber purlin 11 and the C-shaped basalt fiber connection block 1 are bolted together using the C-shaped first steel connection plate 9 and the C-shaped second steel connection plate 10 to achieve a connection method in which the components are not opened and the performance of the basalt fiber is not damaged. The basalt fiber connection block 1 is connected to the square photovoltaic panel 2 by bolts; the fixation between the two can also be achieved by clamping, ensuring a reliable connection without opening holes.

[0049] It can be seen that the connecting column 8, the diagonal brace 6, the basalt fiber rod 12 composed of the basalt fiber sleeve 15 and the double-hook rigid spring 16, and the aluminum friction plate 17 are set in the connecting piece. Considering that under the action of frequent earthquakes and wind loads, the friction energy dissipation node connecting piece can provide sufficient stiffness and damping for the main structure, so that the energy dissipation and shock absorption structure can meet the requirements of normal use. Under the action of fortification earthquakes and rare earthquakes, the energy dissipation and damping device elements first enter the energy dissipation working state, produce greater damping, dissipate the energy in the input structure, quickly attenuate the dynamic response of the structure, and delay the occurrence time of inelastic deformation of the main structure. In addition, the stiffness (also called elastic coefficient) of the double-hook rigid spring 16 is usually used to describe the elastic properties of the spring, which is related to the geometric shape and material properties of the spring; generally speaking, the greater the stiffness, the more difficult it is for the spring to be compressed or stretched, and the smaller the stiffness, the easier it is for the spring to undergo elastic deformation; using a spring with greater stiffness can effectively resist the impact of wind load on the photovoltaic bracket.

[0050] In summary, the present invention provides an energy-consuming basalt fiber photovoltaic bracket without opening holes, which has the following advantages compared with existing plugging tools: First, the non-porous design improves performance: This bracket is constructed by non-porous connection, which effectively avoids the problem of local stress concentration and improves the bearing capacity and stiffness of the overall structure; this design retains the original performance of basalt fiber and ensures that the material advantages can be fully utilized.

[0051] Second, energy-absorbing connections enhance stability: Multiple sets of energy-absorbing connectors are installed on the bracket, including clips, energy-absorbing components and embedded connecting steel plates, which consume part of the energy generated by the external load through friction. Under the action of external loads, the nodes first behave as rigid connections. When the load exceeds the critical friction force, they are transformed into flexible connections, which consume energy through sliding and limit the load transferred to the rods, thereby improving the earthquake and wind resistance of the bracket.

[0052] Third, comprehensive optimization of mechanical properties: This bracket not only solves the problem of decreased mechanical properties and poor stability of existing basalt fiber photovoltaic brackets due to openings, but also significantly improves the durability and safety of the bracket through innovative design.

[0053] Fourth, wide applicability: This bracket is suitable for various geographical and climatic conditions, providing a more reliable and efficient support solution for the photovoltaic industry.

[0054] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
