Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaics, in particular to a flexible photovoltaic bracket. Background Art

[0002] In order to adapt to complex terrain and lightweight settings, flexible photovoltaic brackets are often used. Multiple rows of flexible photovoltaic brackets are arranged in parallel, and stabilization devices are installed to ensure that the photovoltaic brackets can maintain structural stability and stable operation in harsh environments such as strong winds and heavy snow.

[0003] Existing stabilization devices often use a whole unbroken steel cable to connect multiple rows of flexible photovoltaic brackets in series, so as to connect multiple rows of independently set photovoltaic brackets and improve the stability of the overall device. Since the first and last rows of photovoltaic brackets of multiple rows of flexible photovoltaic brackets are often tens of meters apart, and the steel cable is thick and heavy, it is difficult to install the steel cable through multiple rows of flexible photovoltaic brackets by manpower. At the same time, the installed steel cable needs to reach a certain pre-tightening force. It is difficult to complete the pre-tightening of the entire steel cable by manpower alone. Therefore, it is necessary to operate the installation equipment to pre-tighten the steel cable. Due to the complex mountain terrain, manually lifting the installation equipment and walking in the mountains will undoubtedly increase the labor intensity and have certain safety risks. Utility Model Content

[0004] In order to solve the technical problems of existing flexible photovoltaic brackets being difficult to install and having high labor intensity, the utility model provides a flexible photovoltaic bracket which reduces the installation difficulty and labor intensity and reduces the installation cost.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A flexible photovoltaic support comprises at least two groups of photovoltaic supports arranged longitudinally, with connectors arranged in the longitudinal direction, and the multiple groups of photovoltaic supports are connected by the connectors, and each group of photovoltaic supports comprises at least two bases, two cables and photovoltaic modules, the bases are arranged transversely, the lower ends of the bases are fixed to the ground, the bases are connected by cables, and the photovoltaic modules are fixed on the cables, the connectors comprise span stabilizers and connecting ropes, and the span stabilizers are connected between the cables arranged in parallel on each group of photovoltaic supports, and the connecting ropes are used to connect the span stabilizers on two adjacent groups of photovoltaic supports.

[0007] Furthermore, the span stabilizing member has connecting parts extending downwardly from both ends in the longitudinal direction, and the connecting parts are provided with a plurality of vertically arranged mounting holes, and the mounting holes are used for mounting the connecting ropes.

[0008] Furthermore, a diagonal brace is provided between the connecting portion and the span stabilizing member.

[0009] Furthermore, it also includes ground anchor cables and ground anchor piles. The ground anchor cables are arranged at both ends of a group of photovoltaic brackets in the transverse direction. One end of the ground anchor cable is connected to the base, and the other end is connected to the ground through the ground anchor piles.

[0010] Furthermore, it also includes stabilizing cables and stabilizing piles. The stabilizing cables are respectively arranged on the first group of photovoltaic brackets and the last group of photovoltaic brackets of the multiple groups of photovoltaic brackets. One end of the stabilizing cable is connected to the ground through the stabilizing pile, and the other end is connected to the span stabilizing member.

[0011] Furthermore, the span stabilizer is fixed to the cable by means of a U-bolt A.

[0012] Furthermore, the connecting rope and the span stabilizing member are fixed by U-bolts B.

[0013] Furthermore, the connecting rope is a steel wire rope, a steel cable or an alloy rope.

[0014] Furthermore, the cable is a steel wire rope, a steel cable or an alloy rope.

[0015] The beneficial effects of the utility model are:

[0016] 1. This scheme sets up segmented connecting ropes and span stabilizers to pre-tighten multiple groups of photovoltaic brackets to improve overall stability. The span stabilizers are fixed on the cables of a single group to ensure that there is a certain tensile stress between the cables of a single group of photovoltaic brackets. Then the span stabilizers on the two adjacent groups of photovoltaic brackets are connected by connecting ropes. In this way, short-distance installation can be completed by manpower only. The installation distance is only the interval distance between the two groups of photovoltaic brackets. The labor intensity of installation is small, which avoids the need to overcome the accumulated friction of multiple groups of photovoltaic brackets on the connecting rope when using the whole connecting rope. The connecting rope forms a linkage between multiple groups of photovoltaic brackets to jointly resist the vibration and displacement of the arrangement direction of the photovoltaic brackets, thereby improving the wind resistance and stability of the overall structure. At the same time, the use of segmented connecting ropes does not use connecting ropes between the cables of a group of photovoltaic brackets. Only the connecting rope needs to be used to connect the photovoltaic bracket of this group with the adjacent group of photovoltaic brackets, which saves half of the amount of connecting rope and reduces production costs.

[0017] 2. The span stabilizer has connecting parts extending downward from both ends of the left and right sides in the longitudinal direction. The connecting parts are provided with a plurality of vertically arranged mounting holes, and the mounting holes are used to install the connecting rope. When the photovoltaic bracket is installed at different terrain heights, the span stabilizer will also be at different heights. To facilitate manual installation, the installer can select mounting holes at different heights and connect the span stabilizer through the connecting rope. Such a design is suitable for uneven terrain conditions.

[0018] 3. A diagonal brace is provided between the connection part and the span stabilizer. The diagonal brace is provided to strengthen the connection strength between the connection part and the span stabilizer, ensure the stable connection between two adjacent groups of photovoltaic brackets, avoid bending deformation of the connection part, make the pre-tightening force of the connection rope insufficient, and weaken the stability of the overall photovoltaic bracket.

[0019] 4. Setting ground anchor cables on the base can share the forces on the base, such as wind force, snow load and other external forces, and also provide stable tensile stress to the cables to prevent the cables from bending and deforming when affected by external forces and insufficient tensile stress, thereby causing damage to the photovoltaic modules. The setting of ground anchor cables increases the stability and anti-overturning ability of the device.

[0020] 5. Stabilizing cables and stabilizing piles are arranged on the first and last groups of photovoltaic brackets arranged in an array. One end of the stabilizing cable is connected to the ground through the stabilizing pile, and the other end is connected to the span stabilizing member. This forms an effective constraint, which can improve the overall structural stability of the photovoltaic bracket array and reduce vibration and swing caused by wind, earthquake or other external disturbance forces. The stabilizing cable can also absorb the impact force and vibration energy of the photovoltaic modules in the arrangement direction, reducing the hidden dangers of rupture or damage of the photovoltaic modules.

[0021] 6. The span stabilizer is fixed to the cable by U-bolt A. The design of U-bolt A ensures high connection strength and good stability between the two, and is easy to install and disassemble quickly, and convenient for adjusting the position and angle of the span stabilizer.

[0022] 7. The connecting rope is a steel wire rope, steel cable or alloy rope, and the cable is a steel wire rope, steel cable or alloy rope. To ensure that the photovoltaic bracket can effectively withstand and conduct the gravity from the photovoltaic module and the impact of the external environment, the connecting rope and cable need to have good tensile strength and corrosion resistance, and be easy to process and maintain. The processing technology of steel wire rope, steel cable and alloy rope is mature, and can be flexibly cut and joined as needed, and is easy to inspect and maintain.

[0031] Reference Figures 1 to 3 , the utility model provides a flexible photovoltaic bracket.

[0032] In some embodiments, a flexible photovoltaic bracket includes at least two groups of photovoltaic brackets arranged longitudinally, and a connecting piece is arranged in the longitudinal direction. The multiple groups of photovoltaic brackets are connected by the connecting piece. Each group of photovoltaic brackets includes at least two bases 1, two cables 2 and a photovoltaic module 3. The bases 1 are arranged transversely, and the lower ends of the bases 1 are fixed to the ground. The bases 1 are connected by cables 2, and the photovoltaic modules 3 are fixed on the cables 2. The connecting piece includes a span stabilizer 4 and a connecting rope 5. The span stabilizer 4 is connected between the cables 2 arranged in parallel on each group of photovoltaic brackets, and the connecting rope 5 is used to connect the span stabilizers 4 on two adjacent groups of photovoltaic brackets.

[0033] This solution sets up segmented connecting ropes 5 and span stabilizers 4 to pre-tighten multiple groups of photovoltaic brackets to improve overall stability. The span stabilizers 4 are fixed on a single group of cables 2 to ensure that there is a certain tensile stress between the cables 2 of a single group of photovoltaic brackets. The adjacent span stabilizers 4 are then connected by connecting ropes 5. In this way, the pre-tightening can be completed by manpower for short-distance installation. The installation distance is only the spacing distance between two groups of photovoltaic brackets. The labor intensity of the installation is low, and the need to overcome the accumulated friction of multiple groups of photovoltaic brackets on the connecting rope 5 when using the entire connecting rope 5 is avoided.

[0034] It should be noted that each group of photovoltaic brackets includes at least two bases 1 and two cables 2, which means that two or more bases 1 are arranged horizontally, and multiple groups of photovoltaic brackets are arranged vertically. The horizontally arranged bases 1 are connected by two or more cables 2. The number of bases 1 and cables 2 is set according to the site to ensure the rational use of the site area. At the same time, setting multiple bases 1 and cables 2 can improve the strength and stability of the overall photovoltaic bracket. For the setting of the cables 2, the cables 2 can be set to be one high and one low to ensure that the photovoltaic module 3 has a certain inclination angle to cope with the light direction in different periods. At the same time, the height of the cables 2 can also be set in the same horizontal plane, and a device that can rotate around the axis of the length direction of the cables 2 at a certain angle is set on the top of the base 1. The photovoltaic module 3 designed in this way can also adjust the inclination angle, for example, a support plate is set on the top of the base 1, the support plate is hinged to the base 1, and a limiter is set, for example, a pin hole is set at the hinge, and the support plate and the base 1 are fixed by the pin. In addition, a connection kit 12 is provided on the cable 2, and the connection kit 12 is fixed to the cable 2 by bolts. A threaded hole is provided on the upper end of the connection kit 12, and the photovoltaic component 3 is threadedly connected to the threaded hole on the connection kit 12 by screws to achieve the fixation purpose.

[0035] In some embodiments, the span stabilizer 4 has connecting parts extending downward at both ends in the longitudinal direction, and a plurality of vertically arranged mounting holes are provided on the connecting parts, and the mounting holes are used to install the connecting rope 5. When the photovoltaic bracket is installed at different terrain heights, the span stabilizer 4 will also be at different heights. To facilitate manual installation, the installer can select mounting holes at different heights and connect the span stabilizer 4 through the connecting rope 5. Such a design is suitable for uneven terrain conditions.

[0036] In some embodiments, a diagonal brace is provided between the connection part and the span stabilizer 4. The diagonal brace is provided to strengthen the connection strength between the connection part and the span stabilizer 4, ensure the stable connection between two adjacent groups of photovoltaic brackets, avoid bending deformation of the connection part, make the pre-tightening force of the connection rope 5 insufficient, and weaken the stability of the overall photovoltaic bracket.

[0037] In some embodiments, ground anchor cables 6 and ground anchor piles 7 are also included. The ground anchor cables 6 are arranged at both ends of a group of photovoltaic brackets in the transverse direction. One end of the ground anchor cables 6 is connected to the base 1, and the other end is connected to the ground through the ground anchor piles 7. The ground anchor cables 6 are arranged on the base 1 to share the force on the base 1, such as external forces such as wind force and snow load. At the same time, stable tensile stress can be provided to the cable 2 to prevent the cable 2 from bending and deforming when it is affected by external forces and the tensile stress is insufficient, thereby causing damage to the photovoltaic module. The arrangement of the ground anchor cables 6 increases the stability and anti-overturning ability of the device.

[0038] As for how to fix the ground anchor cable 6 to the ground, a fixing device may be provided on the ground, such as a ground anchor pile 7 , and then the ground anchor cable 6 is connected to the ground anchor pile 7 .

[0039] In some embodiments, a stabilizing cable 8 and a stabilizing pile 9 are also included, wherein the stabilizing cable 8 is respectively arranged on the first group of photovoltaic brackets and the last group of photovoltaic brackets of the plurality of photovoltaic brackets, and one end of the stabilizing cable 8 is connected to the ground through the stabilizing pile 9, and the other end is connected to the span stabilizing member 4. Such a design forms an effective constraint, which can improve the overall structural stability of the photovoltaic bracket array and reduce the vibration and swing caused by wind, earthquake or other external disturbance forces. The stabilizing cable 8 can also absorb the impact force and vibration energy of the photovoltaic module 3 in the arrangement direction, reducing the hidden danger of the photovoltaic module 3 being broken or damaged.

[0040] Since at least two groups of photovoltaic brackets are arranged in an array and connected by span stabilizers 4 and connecting ropes 5, a linkage is formed between the multiple groups of photovoltaic brackets. At this time, stabilizing ropes 8 are set on the first and last groups of photovoltaic brackets to fix them to the ground, so as to further strengthen the overall strength, wind resistance and vibration resistance. A fixing device, such as a stabilizing pile 9, is set on the ground. One end of the stabilizing rope 8 is connected to the stabilizing pile 9, and the other end is connected to the span stabilizer 4, so as to strengthen the fixation.

[0041] In some embodiments, the span stabilizer 4 is fixed to the cable 2 by a U-bolt A11. The design of the U-bolt A11 ensures high connection strength and good stability between the two, and is convenient for quick installation and removal, and convenient for adjusting the position and angle of the span stabilizer 4. Of course, welding can also be used for permanent fixation, which can avoid loosening.

[0042] In some embodiments, the connecting rope 5 is fixed to the span stabilizer 4 by a U-bolt B10. The design of the U-bolt B10 ensures high connection strength and good stability between the two, and is convenient for quick installation and disassembly, and is convenient for subsequent maintenance. The connecting rope 5 is pre-tightened again. For example, when the photovoltaic bracket is subjected to external forces such as wind, the connecting rope 5 connecting two adjacent span stabilizers 4 is loose. The U-bolt B10 can be loosened to pre-tighten the connecting rope 5 again, and then the U-bolt B10 and the connecting rope 5 are fixed.

[0043] In some embodiments, the connecting rope 5 is a steel wire rope, a steel cable or an alloy rope.

[0044] In some embodiments, the cable 2 is a steel wire rope, a steel cable or an alloy rope. To ensure that the photovoltaic support can effectively withstand and conduct the gravity from the photovoltaic module 3 and the impact force of the external environment, the connecting rope 5 and the cable 2 need to have good tensile strength and corrosion resistance, and be easy to process and maintain. The processing technology of steel wire ropes, steel cables and alloy ropes is mature, and they can be flexibly cut and joined as needed, and are easy to inspect and maintain.
