Description

Technical Field

[0001] This utility model relates to the field of photovoltaic installation technology, and in particular to a large-span flexible photovoltaic support with deflection control. Background Technology

[0002] The function of photovoltaic panels is to convert solar energy into electrical energy in order to realize energy utilization.

[0003] In existing technologies, a large number of photovoltaic panels are typically installed in locations with ample sunlight using flexible supports. However, due to the presence of greenery, walkways, water features, and other facilities at the installation sites, installation locations are relatively scarce. This results in a large span between the steel cables of two support pillars, leading to significant deflection at the mid-span after the photovoltaic panels are installed on the cables, which is detrimental to structural stability. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a large-span photovoltaic flexible support with deflection control, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A large-span flexible photovoltaic support structure with deflection control includes a support mechanism, a laying mechanism disposed on the support mechanism, and a reinforcing mechanism for strengthening the support mechanism. The support mechanism is arranged in multiple sets at intervals along the longitudinal direction. The support mechanism includes multiple sets of first support structures arranged in the transverse direction and second support structures located on both sides of the first support structures. The first support structure consists of two first support columns arranged symmetrically to each other. The first support column includes a first column body and a first column end integrally formed with the first column body. The first column end is offset in a direction away from the adjacent first support column. The reinforcing mechanism includes a connecting beam connecting the two first column ends, multiple support rods disposed below the connecting beam, and first prestressed steel strands disposed on the multiple support rods. The two ends of the first prestressed steel strands are respectively connected to the two first column ends.

[0007] According to one aspect of the above technical solution, the second support structure is a second support column, which includes a second column body and a second column end integrally formed with the second column body, and the second column end is offset toward the direction close to the first support column.

[0008] According to one aspect of the above technical solution, the strengthening mechanism further includes a second prestressed steel strand, one end of which is connected to the second column end and the other end is connected to the ground.

[0009] According to one aspect of the above technical solution, the laying mechanism includes two third prestressed steel strands disposed between the second column end and the first column end, and between adjacent first column ends, the two third prestressed steel strands being arranged at different heights, and the photovoltaic panel being laid on the two third prestressed steel strands.

[0010] According to one aspect of the above technical solution, the strengthening mechanism further includes a tripod disposed below the two third prestressed steel strands, and a fourth prestressed steel strand connecting each of the tripods in the longitudinal direction.

[0011] According to one aspect of the above technical solution, the longitudinally adjacent tripods are connected by a connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By setting up a support mechanism and placing the laying mechanism on it, multiple photovoltaic panels are sequentially laid on the laying mechanism. Then, a reinforcement mechanism is used to strengthen the support and laying mechanisms, improving their strength and stability. Specifically, in one set of support mechanisms, first and second support structures are respectively set at both ends. Then, multiple sets of first support structures are set between the two second support structures. Each set of first support structures includes two symmetrically arranged first support columns, with the first column ends offset away from the adjacent first support columns. Because the first column ends are offset outwards, the span of the laying mechanism between the first and second support structures, or between two adjacent first support structures, is reduced. With a reduced span, the bending moment at the mid-span of the laying mechanism decreases exponentially, thus helping to reduce the mid-span deflection of the laying mechanism. Due to the laying machine... The structure is generally made of steel strand. Therefore, during use, the steel strand pulls on the first and second support structures, causing them to slightly deform towards the mid-span of the laying mechanism, which also increases deflection. Therefore, this invention also includes a reinforcing mechanism. By setting a connecting beam between the two first column ends, the first column ends of the two first support columns can be effectively held in place, preventing them from shifting towards the mid-span of the laying mechanism. Then, a support rod is set on the support beam to support the first prestressed steel strand, and the two ends of the first prestressed steel strand are connected to the first column ends of the two first support columns respectively. Since the first prestressed steel strand has a pre-existing tension on the first column ends of the two first support columns, this tension can be balanced with the tension of the photovoltaic panels on the first column ends after the photovoltaic panels are laid on the laying mechanism, achieving the stability of the entire structure. At the same time, this structure only extends the first column ends to shift their position towards the laying mechanism, without affecting the space where the first column connects to the ground, thus reasonably reducing the space required.

[0025] Please see Figures 1 to 5The image shows a large-span flexible photovoltaic support with deflection control in the first embodiment of this utility model. It includes a support mechanism, a laying mechanism disposed on the support mechanism, and a reinforcing mechanism 30 for reinforcing the support mechanism. The support mechanism is arranged in multiple sets at intervals along the longitudinal direction. The support mechanism includes multiple sets of first support structures 20 arranged in the transverse direction and second support structures 10 located on both sides of the first support structures 20. The first support structure 20 consists of two first support columns arranged symmetrically to each other. The first support column includes a first column body 21 and a first column end 22 integrally formed with the first column body 21. The first column end 22 is offset in a direction away from the adjacent first support column. The reinforcing mechanism 30 includes a connecting beam 31 connecting the two first column ends 22, multiple support rods 32 disposed below the connecting beam 31, and a first prestressed steel strand 33 disposed on the multiple support rods 32. The two ends of the first prestressed steel strand 33 are respectively connected to the two first column ends 22.

[0026] Understandably, this utility model sets up a support mechanism and places the laying mechanism on the support mechanism, then lays multiple photovoltaic panels 40 sequentially on the laying mechanism. A reinforcing mechanism 30 is then used to strengthen the support mechanism and the laying mechanism, enhancing their strength and stability. Specifically, in a set of support mechanisms, first and second support structures 10 are respectively set at both ends, and multiple sets of first support structures 20 are set between the two second support structures 10. Each set of first support structures 20 includes two symmetrically arranged first support columns, and the first column end 22 of the first support column is offset away from the adjacent first support column. Because the first column end 22 is offset outward, the span of the laying mechanism between the first support structure 20 and the second support structure 10, or between two adjacent first support structures 20, is reduced. With a reduced span, the bending moment at the mid-span of the laying mechanism decreases exponentially, thus helping to reduce the deflection at the mid-span of the laying mechanism. Since the structure is generally made of steel strand, during use, the steel strand will pull on the first support structure 20 and the second support structure 10, causing them to deform slightly toward the mid-span of the laying mechanism, which will also lead to an increase in deflection. Therefore, this utility model also provides a reinforcing mechanism 30. By setting a connecting beam 31 between the two first column ends 22, the first column ends 22 of the two first support columns can be effectively held in place, preventing them from shifting toward the mid-span of the laying mechanism. Then, a support rod 32 for supporting the first prestressed steel strand 33 is set on the support beam, and the two ends of the first prestressed steel strand 33 are respectively connected to the first column ends 22 of the two first support columns. Since the first prestressed steel strand 33 has a pre-existing tension on the first column ends 22 of the two first support columns, after the photovoltaic panel 40 is laid on the laying mechanism, this tension can be balanced with the tension of the photovoltaic panel 40 on the first column ends 22, thus achieving the stability of the entire structure. Meanwhile, the structure only extends the first column end 22 to offset its position toward the laying mechanism, without affecting the space of the part of the first column 21 that connects to the ground, thus reasonably reducing the space required.

[0027] Specifically, in this embodiment, the second support structure 10 is a second support column, which includes a second column body 12 and a second column end 13 integrally formed with the second column body 12. The second column end 13 is offset toward the direction close to the first support column. The reinforcing mechanism 30 also includes a second prestressed steel strand 11, one end of which is connected to the second column end 13 and the other end is connected to the ground.

[0028] Understandably, since the second support column is on both sides, only the tension of the laying mechanism in one direction needs to be considered. Therefore, only one second support column is set. Similarly, since the laying mechanism will pull the second support column, a second prestressed steel strand 11 is set in advance at the end of the second column 13 away from the laying mechanism to balance the tension applied to the second column end 13 by the laying mechanism in the future.

[0029] Furthermore, the laying mechanism includes two third prestressed steel strands 41 disposed between the second column end 13 and the first column end 22, and between adjacent first column ends 22. The two third prestressed steel strands 41 are arranged at different heights, and the photovoltaic panel 40 is laid on the two third prestressed steel strands 41.

[0030] Understandably, the third prestressed steel strand 41 is also pre-tensioned to keep the steel strand taut, in order to balance the weight of the photovoltaic panel 40 after it is laid. The purpose of setting the third prestressed steel strand 41 at high and low positions is so that when the photovoltaic panel 40 is installed in the future, the photovoltaic panel 40 can have an angle to better absorb the sunlight.

[0031] Furthermore, the strengthening mechanism 30 also includes a tripod 50 disposed below the two third prestressed steel strands 41, and a fourth prestressed steel strand 52 connecting each of the tripods 50 in the longitudinal direction; the adjacent tripods 50 in the longitudinal direction are connected by a connecting rod 51.

[0032] Understandably, the tripod 50 is consistent with the prior art, installed below the two third prestressed steel strands 41, and then connected longitudinally by the connecting rod 51 and the fourth prestressed steel strand 52, so that the third prestressed steel strands 41 in the longitudinal direction form a whole, which improves the overall stability.

[0033] It should be noted that all structural components in this utility model are made of steel.

[0034] In summary, the large-span flexible photovoltaic support with deflection control in the above embodiments of this utility model can reduce the deflection at the mid-span of the laying mechanism and improve the installation stability of the photovoltaic panels.
