Description

Technical Field

[0001] This application relates to the field of photovoltaic support technology, and in particular to a photovoltaic support for unstable slopes and its construction method. Background Technology

[0002] With the increase in mountain photovoltaic projects, land use conditions are becoming increasingly demanding. Some photovoltaic projects use unused land in gullies. Due to the large slope of the gullies, they are often unstable, making it difficult for traditional photovoltaic supports to take root. Flexible support solutions require large foundations at both ends, high construction precision, and complex mountain conditions, making it difficult to guarantee the quality of the foundations at both ends of the flexible support, thus making it difficult to guarantee reliability.

[0003] Therefore, it is urgent to study a photovoltaic support system that can be applied to unstable slopes (or minor landslides), which is of great significance for the vigorous development of mountain photovoltaic projects. Summary of the Invention

[0004] This application provides a photovoltaic support structure for unstable slopes and a construction method thereof, which is applicable to unstable slopes or minor landslides.

[0005] The technical solution adopted in this application is as follows:

[0006] In a first aspect, the present invention discloses a photovoltaic support for unstable slopes, comprising multiple sets of fixing mechanisms laid sequentially, each set of fixing mechanisms comprising:

[0007] A briquetting module is located on the sunny side of a mountain peak, and solar cell modules are located on the side of the briquetting module away from the mountain peak. The briquetting module includes multiple sets of briquetting blocks, which are laid out in a mesh pattern.

[0008] The first fixed strand has multiple strands, one end of which is connected to multiple sets of pressure blocks respectively;

[0009] The counterweight module is located on the shady side of the mountain peak. The counterweight module is a counterweight block. Multiple first fixed strands cross the mountain peak and connect to a set of counterweight blocks. The number of counterweight blocks in each set can be different. The number of counterweight blocks in each set is determined according to the tilt angle of the sunny side of the mountain peak, the soil conditions, and the corresponding pressure characteristics of the blocks. The pressure block module and the counterweight module in each set of fixing mechanisms maintain a balance of forces.

[0010] Furthermore, the pressing block is concave in shape, with its opening facing the side of the mountain peak.

[0011] In one feasible implementation, in each set of multiple pressure blocks of the fixing mechanism:

[0012] The adjacent pressure blocks are connected longitudinally by a second fixed strand;

[0013] The adjacent pressure blocks are connected laterally by a rigid rod hinge.

[0014] Furthermore, each set of counterweights is connected to three sets of pressure blocks via three first fixed strands.

[0015] Furthermore, both the first and second fixed strands are steel strands.

[0016] Secondly, the present invention discloses a construction method for a photovoltaic support structure on an unstable slope, for implementing the photovoltaic support structure for an unstable slope as described above, comprising:

[0017] Place multiple inflatable bags connecting the mountaintop and the base of the mountain on the sunny side of the mountain, and fill the inflatable bags with air.

[0018] The first fixing mechanism is assembled at the mountaintop. The fixing mechanism includes a pressure block module, a counterweight module, and a first fixing strand connecting the pressure block module and the counterweight module. The solar cell module is installed on the side of the pressure block module away from the mountain peak. The pressure block module includes multiple sets of pressure blocks laid in a mesh. The counterweight module is a counterweight block. One end of multiple first fixing strands is connected to multiple sets of pressure blocks, and the other end is connected to a set of the counterweight blocks. The number of counterweight blocks in each set can be different.

[0019] The pressure block module and the solar cell module mounted on it in the first set of fixed mechanism are slid down along multiple inflatable bags toward the sunlit side of the mountain. The corresponding counterweight module is then placed down along the shady side of the mountain. The number of counterweight blocks in each set is determined according to the inclination angle of the sunlit side of the mountain, the soil conditions, and the stress characteristics of the corresponding pressure block. The pressure block module and the counterweight module in each set of fixed mechanism are kept in balance.

[0020] After the solar cell modules, the pressure block module, and the counterweight module are all placed down, the air in the air bag is released, allowing the pressure block to land and contact the mountain. The air bag is then removed, completing the construction process of the first set of fixing mechanisms.

[0021] Place multiple air bags on the side adjacent to the first fixing mechanism and fill the air bags with air;

[0022] Assemble a fixed mechanism at the top of the mountain and lower it down, until the entire photovoltaic support system construction process is completed.

[0023] In one feasible implementation, the pressure block is concave in shape with its opening facing the mountain peak, the opening being adapted to the inflatable bag.

[0024] In one feasible implementation, in each set of multiple pressure blocks of the fixing mechanism:

[0025] The adjacent pressure blocks are connected longitudinally by a second fixed strand;

[0026] The adjacent pressure blocks are connected laterally by a rigid rod hinge.

[0027] Furthermore, each set of counterweights is connected to three sets of pressure blocks via three first fixed strands.

[0028] Furthermore, both the first and second fixed strands are steel strands.

[0029] The beneficial effects of adopting the technical solution of this application are as follows:

[0030] The present invention discloses a photovoltaic support structure for unstable slopes and its construction method. The construction method includes: placing multiple inflatable bags connecting the mountaintop and the base of the mountain on the sun-facing side of the mountain peak and filling the bags with air; assembling a first fixing mechanism at the mountaintop, the fixing mechanism including a pressure block module, a counterweight module, and first fixing strands connecting the pressure block module and the counterweight module, wherein the pressure block module includes multiple sets of pressure blocks laid in a mesh, the counterweight module is a counterweight block, one end of the multiple first fixing strands is connected to multiple sets of pressure blocks, and the other end is connected to a set of counterweight blocks, the number of counterweight blocks in each set can be different; and placing the pressure block module and the solar cell modules mounted on it in the assembled first fixing mechanism along the multiple inflatable bags. The solar panels slide down the mountainside towards the sun, and the corresponding counterweight modules are lowered along the shaded side of the mountain. The number of counterweights in each set is determined based on the inclination angle of the sun-facing side of the mountain, the soil conditions, and the stress characteristics of the corresponding weight blocks. The weight blocks and counterweight modules in each fixing mechanism are kept in balance. After the solar panels, weight blocks, and counterweight modules are all lowered, the air in the air bags is released, allowing the weight blocks to land and contact the mountain. The air bags are then removed, completing the construction of the first fixing mechanism. Multiple air bags are placed adjacent to the first fixing mechanism and inflated. The next fixing mechanism is assembled at the mountaintop and lowered, until the entire photovoltaic support system is completed.

[0031] The solar cell modules of this invention are arranged on weighted blocks, which are laid in a mesh pattern to form a stable structure. Simultaneously, a first fixed strand connects the weighted blocks on the sunny side to the counterweight blocks on the shady side at the top of the beam. The weighted blocks prevent the solar cell modules from being overturned by wind loads, while the counterweight blocks prevent the solar cell modules from sliding down the mountainside.

[0032] The counterweight of this invention provides a pulling effect on the pressure block, and is suitable for unstable slopes or minor landslides.

[0033] Furthermore, the installation process of the solar cell modules of the present invention is completed on the top of the beam, which maximizes both efficiency and safety. Attached Figure Description

[0046] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the claims.

[0047] Traditional photovoltaic (PV) support systems require the construction of terraced fields and zigzag roads, or the use of suspended piling machines, resulting in low efficiency and unreliable safety. Furthermore, traditional PV systems employ flexible support structures with massive foundations at both ends, demanding high construction precision. Complex mountainous terrain makes it difficult to guarantee the quality of the foundations at both ends of the flexible support system, thus compromising its reliability.

[0048] Therefore, the present invention provides a photovoltaic support for unstable slopes and a construction method thereof to solve the above problems, as detailed below.

[0049] See Figures 1 to 5b .

[0050] In a first aspect, the present invention discloses a photovoltaic support for unstable slopes, comprising multiple sets of fixing mechanisms laid sequentially, each set of fixing mechanisms comprising:

[0051] A briquetting module is located on the sunny side of a mountain peak, and solar cell modules are located on the side of the briquetting module away from the mountain peak. The briquetting module includes multiple sets of briquetting blocks, which are laid out in a mesh pattern.

[0052] The first fixed strand has multiple strands, one end of which is connected to multiple sets of pressure blocks respectively;

[0053] The counterweight module is located on the shady side of the mountain peak. The counterweight module is a counterweight block. Multiple first fixed strands cross the mountain peak and connect to a set of counterweight blocks. The number of counterweight blocks in each set can be different. The number of counterweight blocks in each set is determined according to the tilt angle of the sunny side of the mountain peak, the soil conditions, and the corresponding pressure characteristics of the blocks. The pressure block module and the counterweight module in each set of fixing mechanisms maintain a balance of forces.

[0054] Furthermore, the pressing block is concave in shape, with its opening facing the side of the mountain peak.

[0055] In one feasible implementation, in each set of multiple pressure blocks of the fixing mechanism: adjacent pressure blocks are connected longitudinally by a second fixing strand; adjacent pressure blocks are hinged laterally by a rigid rod, wherein, in this embodiment, the second fixing strand is a steel strand. The pressure blocks are hinged laterally by a rigid rod to ensure that adjacent modules will not be excessively compressed, leading to deformation and damage, in the event of a minor landslide.

[0056] Furthermore, each set of counterweights is connected to three sets of pressure blocks via three first fixed strands.

[0057] It is understood that in this embodiment, the pressure block and the counterweight are specifically concrete blocks. Of course, other suitable products can also be used as pressure blocks and counterweights, which will not be elaborated here. It should also be noted that, in order to save land and construction costs, the volume and weight of the counterweight are much larger than that of the pressure block. Increasing the weight of the counterweight per unit area is beneficial to controlling construction costs. The shape and weight of the pressure block should match the solar cell module and are usually relatively fixed.

[0058] In one feasible implementation, both the first and second fixed strands are steel strands, with one end connected to the pressure block module and the other end connected to the counterweight module. In this embodiment, using steel strands for both the first and second fixed strands provides better tension and ensures a longer service life.

[0059] It should be noted that the counterweights are devices to prevent the solar panels from sliding down the mountainside. The number and weight of each counterweight can be adjusted in real time according to the terrain, but the forces on both sides of the mountainside should be balanced. Factors determining the number of counterweights include: ① the length of the weights laid on the sunny side of the mountain; ② the steepness of the mountainside where the weights are laid; ③ the soil conditions (friction coefficient); ④ the stress characteristics of the weights, etc. Specifically:

[0060] In this invention, solar cell modules are arranged on weighted blocks. Adjacent blocks are connected longitudinally by steel strands and laterally by rigid rods, forming a mesh. At the top of the beam, they are connected to a counterweight block on the shaded side by steel strands. The weighted blocks prevent the solar cell modules from being overturned by wind loads, the counterweight blocks prevent the solar cell modules from sliding down the mountainside, and the laterally rigid rods connecting the weighted blocks ensure that adjacent modules are not excessively compressed and deformed or damaged during minor landslides.

[0061] Secondly, the present invention discloses a construction method for a photovoltaic support structure on an unstable slope, for implementing the photovoltaic support structure for an unstable slope as described above, comprising:

[0062] S100: Place multiple inflatable bags connecting the mountaintop and the base of the mountain on the sunny side of the mountain peak, and fill the inflatable bags with air.

[0063] S200: Assemble the first fixing mechanism at the mountain top. The fixing mechanism includes a pressure block module, a counterweight module, and a first fixing strand connecting the pressure block module and the counterweight module. The solar cell module is installed on the side of the pressure block module away from the mountain peak. The pressure block module includes multiple sets of pressure blocks laid in a mesh. The counterweight module is a counterweight block. One end of multiple first fixing strands is connected to multiple sets of pressure blocks, and the other end is connected to a set of the counterweight blocks. The number of counterweight blocks in each set can be different.

[0064] In one feasible implementation, the pressure block is concave in shape with its opening facing the mountain peak, the opening being adapted to the inflatable bag.

[0065] In one feasible implementation, in each set of multiple pressure blocks of the fixing mechanism: adjacent pressure blocks are connected longitudinally by a second fixed strand; and adjacent pressure blocks are hinged laterally by a rigid rod.

[0066] S300: The pressure block module and the solar cell module mounted on it in the first set of fixed mechanisms are slid down along multiple inflatable bags toward the sunlit side of the mountain. The corresponding counterweight module is then placed down along the shady side of the mountain. The number of counterweight blocks in each set is determined according to the inclination angle of the sunlit side of the mountain, the soil conditions, and the stress characteristics of the corresponding pressure block. The pressure block module and the counterweight module in each set of fixed mechanisms are kept in balance.

[0067] S400: After the solar cell module, the pressure block module, and the counterweight module are all placed down, release the air from the air bag, allowing the pressure block to land and make contact with the mountain. Then, remove the air bag to complete the construction process of the first set of fixing mechanisms.

[0068] S500: Place multiple air bags on the side adjacent to the first fixed mechanism and fill the air bags with air.

[0069] S600: Assemble the next set of fixing mechanisms at the top of the mountain, and repeat steps S22 to S400 until the entire photovoltaic support construction process is completed.

[0070] Furthermore, each set of counterweights is connected to three sets of pressure blocks via three first fixed strands.

[0071] Both the first fixed strand and the second fixed strand are steel strands.

[0072] The solar cell modules of this invention are arranged on weighted blocks, which are laid in a mesh pattern to form a stable structure. Simultaneously, a first fixed strand connects the weighted blocks on the sunny side to the counterweight blocks on the shady side at the top of the beam. The weighted blocks prevent the solar cell modules from being overturned by wind loads, while the counterweight blocks prevent the solar cell modules from sliding down the mountainside.

[0073] The counterweight of this invention provides a pulling effect on the pressure block, and is suitable for unstable slopes or minor landslides.

[0074] Furthermore, the installation process of the solar cell modules of the present invention is completed on the top of the beam, which maximizes both efficiency and safety.

[0075] The photovoltaic support structure and construction method of this invention can be used in all mountain photovoltaic projects. This can help achieve peak carbon emissions and carbon neutrality.
