Description

Technical Field

[0001] The present invention relates to the field of photovoltaics, and in particular to a photovoltaic flexible support structure. Background Art

[0002] Photovoltaic flexible brackets are mainly used in new photovoltaic bracket forms in photovoltaic projects under different scenarios. They have the structural advantages of large span and high clearance, and have broad application prospects in various terrains such as mountains or fish ponds. Among the flexible bracket solutions currently on the market, the three-cable solution usually adopts two methods. One is to set up a spatial structure, and the lower end of the spatial structure is connected to the third cable. This design is laborious and time-consuming to install, and the installation cost is high. The other is to set up a spatial connecting rod structure. The reliable spatial connecting rod structure enables the flexible bracket to form a cable net structure in space. Since the flexible bracket uses steel strands as the main bearing material, the overall stiffness of the bracket is low.

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] In a first aspect of the present invention, a photovoltaic flexible support structure is provided, such as Figure 1 , Figure 2 As shown, it includes several photovoltaic support assemblies arranged at intervals, the photovoltaic support assemblies include several main cables 1 and at least one wind-resistant cable 2, the main cables 1 and the wind-resistant cables 2 are both kept in a tensioned state, and the several main cables 1 are located in the same plane to form a bearing base surface, the photovoltaic flexible support structure also includes several wind-resistant stabilization systems, the wind-resistant stabilization systems include wind-resistant frames and connection units connecting adjacent wind-resistant frames, the wind-resistant frames correspond to the support assemblies, and the wind-resistant frames are used to connect the main cables 1 and the wind-resistant cables 2;

[0036] The wind-resistant structure comprises a support unit, a rigid unit, and a first tension unit and a second tension unit disposed between the support unit and the rigid unit, wherein the support unit is fixed to a main cable 1 of a corresponding support assembly, and the connecting unit is fixedly connected to adjacent support units;

[0037] The rigid unit is fixed on the wind-resistant cable 2 to keep the first tension unit and the second tension unit in a tensioned state, so that a flexible spatial triangular structure is formed between the first tension unit, the second tension unit and the supporting unit.

[0038] In this embodiment, there are preferably two main cables 1 and one wind-resistant cable 2, and the wind-resistant cable 2 is preferably located below the main cable 1 to form a commonly used three-cable structure. The bearing base formed by the two main cables 1 is used to bear the photovoltaic panel. In a single photovoltaic support assembly, a flexible space triangular structure is formed between the first tension unit, the second tension unit and the support unit, so that the three form a completely reliable wind-proof and stable system. The connecting unit is then used to connect the adjacent wind-resistant structures in the adjacent photovoltaic support assemblies, so that the front and rear photovoltaic support assemblies are connected into a whole to form a complete stable system that can withstand greater wind pressure, snow pressure, self-weight and other pressures. The plane where the flexible space triangular structure is located can be inclined at a certain angle to the horizontal plane, or it can be perpendicular to the horizontal plane. When the photovoltaic support assembly is subjected to external impact force, if it is inclined at a certain angle to the horizontal plane, the force on the first tension unit and the second tension unit will have a component force in the horizontal direction, which will pull the wind-resistant cable 2. Therefore, it is best to design the plane to be perpendicular to the horizontal plane to minimize the pulling of the wind-resistant cable 2. In addition, in a wind-resistant stable system, the planes where several flexible space triangular structures are located are preferably located in the same plane. On the one hand, it is convenient to find the installation position during installation, and on the other hand, it can increase the wind resistance of the entire structure. If the planes where several flexible space triangular structures are located are staggered, this will cause the length of the connection unit connecting adjacent wind-resistant structures to increase or the length of other components to increase, which is not conducive to the stability of the entire structure and increases the cost. In addition, while the structure is easy to install, it can also adjust the height of the rigid unit. Using this structure, a simple installation surface can be set up on the rigid unit, which is convenient for workers to fix the photovoltaic panels on the bearing base surface through fasteners 18 after the photovoltaic panels are laid on the bearing base surface. The present invention can greatly increase the overall rigidity of the structure, and can also enable the flexible bracket to effectively resist the flutter and vibration caused by wind loads in the case of a large span, thereby avoiding component torsion leading to structural failure, effectively reducing the overall cost of the structure, and improving installation efficiency.

[0039] In the photovoltaic support assembly, the bearing base surface can be parallel to the horizontal plane, so that the photovoltaic panels installed on it are also parallel to the horizontal plane. However, considering that when sunlight shines on the earth, the angle of light will affect the incident angle and light intensity of the light, the parallel setting cannot make full use of the sun's light energy. Therefore, here, Figure 1 , Figure 2 As shown, preferably, the main cables 1 are parallel to each other, and the height of the main cables 1 from the horizontal plane in the vertical direction is gradually reduced to tilt the bearing base surface, and the tilt angle is adapted to the location where the device is installed, so that the photovoltaic panels on the bearing base surface can maximize the use of solar energy.

[0040] As an implementation method, Figure 1, Figure 2 As shown, the first tension unit includes at least one first side cable 6, the second tension unit includes at least one second side cable 7, and the support unit includes at least one support link 8, to which at least one first side cable 6 and at least one second side cable 7 are connected, and the connection positions of the first side cable 6 and the second side cable 7 on the support link 8 are different.

[0041] The above all form multiple flexible space triangular structures in a wind-resistant structure to ensure the stability of the wind-resistant structure. For example, if the support unit only includes one support link 8, and multiple first side cables 6 and multiple second side cables 7 are connected to the support link 8, then the support link 8 will form a flexible space triangular structure with each first side cable 6 and second side cable 7. That is, multiple flexible space triangular structures will be formed through one support link 8. Although this can be installed in actual operation, it will inevitably increase a lot of material and labor costs. If the support unit includes multiple support links 8, in combination with the above configuration, more flexible space triangular structures will be formed. Similarly, although the stability is increased, considering the cost issue and taking into account stability, it is usually like this in practice. Figure 1 , Figure 2 As shown, the first tension unit has a first side cable 6, the second tension unit has a second side cable 7, and the support unit has a support link 8, so that a flexible space triangle structure is formed in each wind-resistant structure, which can ensure the stability of the overall structure and save costs. Here, the first side cable 6 is connected to the support link 8 at the first connection position, and the second side cable 7 is connected to the support link 8 at the second connection position. The first connection position and the second connection position are arranged on both sides of the rigid unit. Compared with the first connection position and the second connection position being located on the same side of the rigid unit, this design forms a more stable flexible space triangle structure formed by the two.

[0042] Of course, even if the first connection position and the second connection position are arranged on both sides of the rigid unit, there may be two typical situations. The first situation is that the first connection position and the second connection position are both located inside the bearing base surface. The second situation is that Figure 1 , Figure 2 As shown, the first connection position and the second connection position are both located outside the bearing base surface. The difference between the two methods lies in the different positions of the connection points. The connection points are outside the bearing base surface. When the bearing base surface is subjected to external force, the first side cable 6 and the second side cable 7 can share more external force. Therefore, preferably, the first connection position and the second connection position are both located outside the bearing base surface.

[0043] As an implementation method, Figure 1 , Figure 2 , Figure 6As shown, the rigid unit includes a rigid bracket 5 and a connecting platform 19 arranged on the rigid bracket 5. The rigid bracket 5 is fixedly connected to the wind-resistant cable 2. One end of the first side cable 6 and one end of the second side cable 7 are both fixed to the connecting platform 19. Here, two external support plates are preferably arranged between the rigid bracket 5 and the connecting platform 19 to form a stable triangular structure to ensure the stability of the rigid unit.

[0044] Here, a connection method between the inter-row connecting rod 9 and the supporting connecting rod 8 is introduced, such as Figure 1 , Figure 2 As shown, one end of the support link 8 is the first connecting end, the other end of the support link 8 is the second connecting end, and the connecting unit includes at least one inter-row connecting rod 9; between adjacent support links 8, one end of the inter-row connecting rod 9 is fixed to the first connecting end of one of the support links 8, and the other end of the inter-row connecting rod 9 is fixed to the second connecting end of another support link 8.

[0045] As an implementation method, Figure 1 , Figure 5 As shown, the photovoltaic flexible support structure also includes:

[0046] A plurality of connecting members are arranged at intervals on the bearing base surface, and a fixing area is formed between adjacent connecting members. The connecting members include fasteners 18 corresponding to the main cables 1, and the fasteners 18 are fixed to the corresponding main cables 1;

[0047] A frame 3 is provided in the fixing area, the frame 3 is used to install the photovoltaic panel, and the frame 3 is fixedly connected to the fastener 18 in the fixing area.

[0048] In this embodiment, the frame 3 is rectangular, and each bearing base frame 3 is arranged side by side. After the photovoltaic panels are installed, the frames 3 on adjacent bearing bases do not affect each other's normal illumination, thereby ensuring the power generation efficiency of the photovoltaic panels.

[0049] In order to ensure the tension of the main cable 1 and the wind-resistant cable 2, Figure 1 , Figure 3 As shown, the photovoltaic support assembly also includes a cable unit arranged on both sides of the bearing base surface, the cable unit is used to provide tension to the main cable 1 and the wind-resistant cable 2, and the cable unit includes:

[0050] A first pile foundation 10 and a column 12 fixed on the first pile foundation 10, the column 12 corresponds to the main cable 1, and the end of the main cable 1 is fixed on the corresponding column 12;

[0051] A second pile foundation 11 is arranged outside the first pile foundation 10, and the second pile foundation 11 is connected to the first pile foundation 10 via a fixing member;

[0052] An auxiliary cable 13 is provided between the second pile foundation 11 and the column 12, and the auxiliary cable 13 is used to provide an outward pulling force to the column 12;

[0053] A plurality of horizontal bars 14 connecting the uprights 12;

[0054] A tensioning cable 4 is used to maintain the tension of the wind-resistant cable 2 , one end of the tensioning cable 4 is fixed to the column 12 , and the other end of the tensioning cable 4 is fixed to the rigid bracket 5 closest to the column 12 .

[0055] In this embodiment, the first pile foundation 10 can provide a stable tensioning force to the main cable 1 and the wind-resistant cable 2. Considering that the main cable 1 and the wind-resistant cable 2 need to support a large number of frames 3, photovoltaic panels and other components, a second pile foundation 11 and an auxiliary cable 13 are also provided here to maintain the windproof stability of the column 12 and improve the service life of the entire photovoltaic system. The horizontal bars 14 between adjacent columns 12 can effectively ensure that the column 12 is deformed under long-term tension.

[0056] Considering that the span of the bearing base is long, the main cable 1 and the wind-resistant cable 2 will form a parabolic droop under the gravity of themselves and other components, which is very unfavorable to maintaining the stability of the bearing base. Therefore, as an implementation method, Figure 1 , Figure 4 As shown, the photovoltaic support assembly also includes at least one bearing unit arranged between the cable units, the bearing unit includes a third pile foundation 15, a bearing column 16 arranged on the third pile foundation 15 and a bearing platform 17 arranged on the bearing column 16, the main cable 1 is fixed on the bearing platform 17, each bearing unit divides the wind-resistant cable 2 passing through the bearing unit into two parts, and the divided ends of the wind-resistant cable 2 are fixed on the corresponding bearing columns 16.
