Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic brackets, and particularly relates to a complex mountain adaptive lightweight multi-point cross-column photovoltaic bracket. Background Art

[0002] With the continuous growth of the global demand for renewable energy, as a clean and sustainable energy form, the newly installed capacity of photovoltaic power generation has continued to maintain a high growth trend. However, with the accelerated construction of photovoltaic power stations, the land resources with superior light resources, flat terrain, and ideal construction conditions are becoming increasingly scarce, becoming one of the bottlenecks restricting the further development of the photovoltaic industry. Under this background, the screening criteria for photovoltaic construction land have gradually become more stringent. In particular, the number of mountain photovoltaic power stations has gradually increased in recent years, becoming a new hot spot in the construction of photovoltaic power stations. Compared with flat photovoltaic power stations, the construction of mountain photovoltaic power stations faces more complex geographical environments and climatic conditions, requiring higher design and construction levels. At the same time, mountain photovoltaic power stations also have their unique advantages. For example, the slope of the mountain can be used to increase the installation angle of the photovoltaic panels, thereby increasing the light reception amount and improving the power generation efficiency.

[0003] However, complex mountains are generally designed according to conventional brackets: the foundation uses bored cast-in-place piles, and the brackets use single-column or double-column steel brackets. In this conventional design scheme, if the mountain slope is large and the geology is complex, the construction and installation are difficult, and the construction cost is also much higher than that of flat photovoltaic and water surface photovoltaic. A large mountain slope means that the installation of the photovoltaic bracket requires more delicate and complex adjustments to ensure that the photovoltaic panels can be stably fixed on the hillside and receive sunlight to the maximum extent. This not only requires higher construction techniques and stricter quality control but may also require additional support structures and reinforcement measures, thus increasing the material and labor costs. Different geological layers, rock types, and soil types may all affect the stability and safety of the photovoltaic bracket. Therefore, the construction of photovoltaic power stations in complex mountains needs to fully consider the influence of terrain and geological conditions, and adopt more flexible and innovative design schemes to reduce the construction difficulty and cost, and improve the economy and feasibility of photovoltaic power stations. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the problems of difficult construction of the bracket foundation in mountain photovoltaic projects, heavy and difficult installation of bracket components, and low safety, and proposes a complex mountain adaptive lightweight multi-point cross-column photovoltaic bracket.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A complex mountain-adaptive lightweight multi-point cross-column photovoltaic support, including single-anchor foundations. The single-anchor foundations are arranged in two columns, and each column of single-anchor foundations includes several single-anchor foundations. One column of single-anchor foundations is staggered with the other column of single-anchor foundations. One end of the single-anchor foundation is installed on the mountain, and the other end of the single-anchor foundation is connected to one end of the cross column. The other end of the cross column is connected to the inclined beam, and photovoltaic modules are installed on the inclined beam.

[0007] Further, two inclined beams are provided, and the two inclined beams are on the same inclined plane. The single-anchor foundation is perpendicular to the inclined plane where the two inclined beams are located.

[0008] Further, several groups of cross columns are provided. Each group of cross columns includes a first column and a second column, and the first column and the second column are cross-set.

[0009] Further, one end of the first column is connected to a single-anchor foundation in one column, and one end of the second column is connected to a single-anchor foundation in the other column. A single-anchor foundation in one column and a single-anchor foundation in the other column are adjacent in the staggered arrangement. The other end of the first column is connected to an inclined beam along the inclined angle direction of the single-anchor foundation in one column at one end of the first column, and the other end of the second column is connected to the other inclined beam along the inclined angle direction of the single-anchor foundation in the other column at one end of the second column.

[0010] Further, the intersection point where the first column and the second column cross is connected in an adjustable manner.

[0011] Further, the adjustable connection adopts a single bolt and a gasket.

[0012] Further, one end of the single-anchor foundation is connected to the cross column in a hinged manner.

[0013] Further, two inclined beams are provided, and the two inclined beams are arranged in parallel. The inclined beam is made of U-shaped steel.

[0014] Further, the other end of the cross column is connected to the inclined beam in a hinged manner.

[0015] Further, the hinged connection adopts a triangular connecting piece.

[0016] Compared with the prior art, the utility model has the following beneficial technical effects:

[0017] For the complex mountain-adaptive lightweight multi-point cross-column photovoltaic support provided by the utility model, the single-anchor foundations are arranged in two columns, and each column of single-anchor foundations includes several single-anchor foundations. One column of single-anchor foundations is staggered with the other column of single-anchor foundations. The staggered single-anchor foundations support the cross column through multi-point arrangement, reducing the bearing capacity of a single foundation. Thus, the foundation materials and construction tools are lightened, the construction difficulty is reduced, and the installation safety of the photovoltaic support is improved.

[0018] Furthermore, the column section optimization can form a stable scissors bracing structure through innovative intersections. One end of the single-anchor foundation is hingedly connected to the intersecting columns, and the other end of the intersecting columns is hingedly connected to the inclined beam. Both the columns and the inclined beam are U-shaped bottom porous components, and the intersection points can be adjusted according to the terrain and the inclination angle of the components. This realizes the adjustable inclination angle of a single group of photovoltaic modules, and the support conforms to the slope and has a stable overall new structure system.

[0019] Furthermore, on mountain slopes with large gradients, it is difficult for large machinery to climb slopes and carry out operations. Compared with cast-in-place piles, the construction machinery for the multi-point single-anchor foundation becomes lighter. The single-anchor construction can be carried out by a single person carrying lightweight drilling equipment. This reduces the mechanical and labor costs.

[0020] Furthermore, the light columns are cross-braced, effectively solving the problems of insufficient cross-section strength and stability caused by the small cross-section of a single column, and replacing the construction difficulty of large-diameter columns.

[0021] Furthermore, the adjustable function of the cross-shaped columns can effectively adapt to different slopes and complex mountain terrains. The overall climbing ability of the support system has been effectively improved in terms of its own stability and construction and installation.

[0022] Furthermore, the single modules are arranged horizontally in a standard array and arranged north-south along the slope. Compared with the single-row or double-row arrangement of the array in the east-west direction, the array spacing between the modules is reduced. This effectively saves the land occupation area of the field area and effectively improves the land utilization rate.

[0023] A complex mountain self-adaptive lightweight multi-point cross-column photovoltaic support provided by the present utility model innovatively designs from the aspects of lightweight construction machinery, simplified manual operation, and the design of the installation structure support itself. At the same time, considering aspects such as the reinforcement of the foundation slope of the photovoltaic array field area, it solves a series of problems such as the difficult construction of the support foundation for mountain photovoltaic projects, the heavy and difficult installation of support components, and low safety. By solving the above problems, more installation capacity can be obtained for mountain photovoltaic projects with more demanding construction conditions, and the purpose of cost reduction and efficiency increase can be achieved.

[0031] Embodiment 1

[0032] A complex mountain-adaptive lightweight multi-point cross-column photovoltaic bracket includes a single-anchor foundation 1. The single-anchor foundation 1 is arranged in two columns. Each column of the single-anchor foundation 1 includes several single-anchor foundations 1. One column of the single-anchor foundation 1 and the other column of the single-anchor foundation 1 are arranged staggeredly. One end of the single-anchor foundation 1 is installed on the mountain, and the other end of the single-anchor foundation 1 is connected to one end of the cross column 2. The other end of the cross column 2 is connected to the inclined beam 3, and the photovoltaic module 4 is installed on the inclined beam 3.

[0033] The bolt is the most basic component of roadway support in contemporary coal mines, which reinforces the surrounding rock of the roadway together so that the surrounding rock supports itself. Bolts are not only used in mines but also in engineering technology to reinforce the main bodies of slopes, tunnels, and dams. As a tension member that penetrates deep into the ground, one end of the bolt is connected to the engineering structure, and the other end penetrates deep into the ground. The whole bolt is divided into a free section and an anchorage section. The free section refers to the area that transmits the tension at the bolt head to the anchor body, and its function is to apply prestress to the bolt. The anchorage section refers to the area where the cement paste bonds the prestressed tendon to the soil layer, and its function is to increase the bond friction between the anchor body and the soil layer, enhance the bearing pressure of the anchor body, and transmit the tension of the free section to the deep soil layer.

[0034] The construction of the single-bolt foundation 1 does not rely on large drilling machines or grouting equipment, but can use lightweight drilling tools carried by a single person for operation. This lightweight tool is not only small in size and light in weight, making it easy to move and operate in steep mountainous areas, but also greatly reduces the requirements for the roads and sites at the construction site. In the construction of mountain photovoltaic power stations, in the face of the challenges of large slopes and complex terrain, traditional heavy construction machinery is often difficult to operate effectively, which not only increases the construction difficulty but also significantly raises the mechanical and labor costs. In contrast, using the multi-point single-bolt foundation 1 as the foundation form of the photovoltaic support 4 has significant construction convenience and cost-saving advantages.

[0035] The design of the single-bolt foundation 1 allows for flexible adjustment according to the changes in the terrain. In mountainous environments, the terrain fluctuates, and traditional cast-in-place pile foundations are often difficult to adapt to such changes, while the single-bolt foundation 1 can adapt to different terrain conditions by adjusting the layout and depth of the bolts.

[0036] The single-bolt foundation 1 is arranged in two rows, and multiple bolts are installed on the mountain at one foundation point. These bolts jointly bear the load of the upper structure, can disperse the load, and reduce the bearing capacity requirements of a single foundation. Since the bearing capacity requirements of a single foundation are reduced, lighter and lower-cost foundation materials can be used. In complex mountain projects, factors such as large slopes and complex geology increase the construction difficulty. The single-bolt foundation 1 disperses the load through multi-point layout, reduces the requirements for foundation treatment, and lowers the construction difficulty and risks. The combined action of two rows of multiple single-bolt foundations 1 can better resist the influence of external loads and geological changes on the photovoltaic modules 4, and improve the stability and safety of the overall structure.

[0037] Two inclined beams 3 are provided, and the two inclined beams 3 are on the same inclined plane. The single-bolt foundation 1 is perpendicular to the inclined plane where the two inclined beams 3 are located. Several groups of cross columns 2 are provided, and each group of cross columns 2 includes a first column and a second column, and the first column and the second column are cross-set.

[0038] The scissors brace structure can effectively disperse and resist external loads, improving the stability of the overall structure. Even under complex terrain or adverse weather conditions, it can ensure the stability of the photovoltaic support system.

[0039] One end of the first upright column is connected to a single anchor bolt foundation 1 of one row, and one end of the second upright column is connected to a single anchor bolt foundation 1 of another row. A single anchor bolt foundation 1 of one row is adjacent to a single anchor bolt foundation 1 of another row in a staggered arrangement. The other end of the first upright column is connected to an inclined beam 3 along the diagonal direction of a row of single anchor bolt foundations 1 at one end of the first upright column, and the other end of the second upright column is connected to another inclined beam 3 along the diagonal direction of a row of single anchor bolt foundations 1 at one end of the second upright column. The intersection point where the first upright column and the second upright column cross is connected in an adjustable manner. The adjustable connection uses a single bolt and a gasket 5.

[0040] One end of the single anchor bolt foundation 1 is connected to the cross upright column 2 in a hinged manner. Two inclined beams 3 are provided, and the two inclined beams 3 are arranged in parallel. The inclined beam 3 is made of U-shaped steel. The other end of the cross upright column 2 is connected to the inclined beam 3 in a hinged manner. The hinged connection uses a triangular connecting piece 6.

[0041] A hinged connection is adopted between the single anchor bolt foundation 1 and the cross upright column 2, and then a hinged connection is made between the cross upright column 2 and the inclined beam 3. Such a design not only reduces the weight but also enhances the stability and flexibility of the structure. The hinged connection allows the upright column and the inclined beam 3 to be finely adjusted within a certain range to adapt to terrain changes or adjust the inclination angle of the photovoltaic module 4, while maintaining the overall stability of the structure. This flexibility not only improves the construction efficiency but also reduces the dependence on terrain conditions. The inclination angle of a single group of photovoltaic modules 4 can be adjusted, and the orientation and inclination angle of the photovoltaic module 4 can be optimized according to the incident angle of sunlight and seasonal changes, thereby improving the power generation efficiency.

[0042] Embodiment 2

[0043] A complex mountain adaptive lightweight multi-point cross upright column photovoltaic support. The photovoltaic modules 4 installed on the complex mountain are arranged in a north-south direction along the slope. Two inclined beams 3 are installed in the north-south direction under the photovoltaic modules 4 to support the photovoltaic modules 4. The two inclined beams are arranged in parallel on the east and west sides. Cross upright columns 2 are installed under the inclined beams 3. The cross upright columns 2 are fixed on the complex mountain through single anchor bolt foundations 1 arranged in two rows in a staggered manner in the east-west direction. A number of groups of cross upright columns 2 are provided. Each group of cross upright columns 2 includes a first upright column and a second upright column. The single anchor bolt foundation 1 on the west side of the row is connected to the inclined beam on the east side through the first upright column, and the single anchor bolt foundation 1 on the east side of the row is connected to the inclined beam on the west side through the second upright column. The connection points are all hinged. The first upright column and the second upright column are cross-connected in a scissor-like manner to form a scissors brace structure, and the scissor-like intersection is connected by bolts. By adjusting the bolts, the cross angle between the first upright column and the second upright column is adjusted, and further the hinged connection points are adjusted, thereby changing the distance and angle between the single anchor bolt foundation and the inclined beam.

[0044] Since the photovoltaic modules 4 can make the best use of the direct sunlight angle when arranged in the north-south direction, the shadow occlusion problem between the modules is effectively alleviated. Therefore, compared with the east-west arrangement, the north-south arrangement can reduce the array spacing between the modules. By adopting the single-module horizontal row arrangement and the north-south arrangement along the slope, the installation density of the photovoltaic modules can be increased without increasing the additional land occupation, thus effectively saving the land occupation area of the field area and improving the land utilization rate. The photovoltaic modules arranged in the north-south direction can better receive the direct radiation of sunlight and reduce the light energy loss caused by the angle deviation. At the same time, reducing the array spacing between the modules also helps to reduce the shadow occlusion between the modules and improve the overall light energy collection efficiency. Therefore, this arrangement method is not only beneficial to saving land, but also helps to improve the power generation efficiency of the photovoltaic power station.

[0045] It is different from the conventional foundation pile fixed support and the flexible support installation method. It is intended to replace the conventional bulky support structure form with a new type of support structure that is light, has a stable structure, is easy to construct, and has a stronger climbing ability. If this support scheme can be promoted, it will strengthen the construction of mountain photovoltaic power stations. The lightweight design makes the transportation and installation processes more convenient, further reducing the construction difficulty and cost. The support system follows the slope and can better adapt to complex terrain and topographic changes, reducing the occupation and damage of land resources.

Therefore, the scope of this teaching should not be determined with reference to the above description, but should be determined with reference to the full scope of the foregoing claims and the equivalents of these claims.
