Embodiment 1

[0039] This embodiment provides a single-axis tracking flexible photovoltaic support, see figure 1 , including a drive device and a vertically arranged bracket body;

[0040] One side of the bracket body is fixedly connected with an arc-shaped slide rail mechanism 4, and the arc-shaped slide rail mechanism 4 is provided with a rotating beam 5, and the rotating beam 5 is used for anchoring the flexible cable 6 supporting the photovoltaic panel 7, so Both ends of the rotating beam 5 are supported on the arc-shaped sliding rail mechanism 4 , and the driving device drives the rotating beam 5 to rotate along the arc-shaped sliding rail mechanism 4 .

[0041] In this solution, the single-axis tracking flexible photovoltaic support is fixedly arranged on the support body, such as fixedly arranged on the ground. The existing bracket body has a single vertical column 1 and is provided with a diagonal pull on the side away from the photovoltaic panel 7, but the structural stability is ...

Embodiment 2

[0054] This embodiment provides a single-axis tracking type flexible photovoltaic support. Compared with the embodiment, this embodiment is more specific. See Figure 1-4 .

[0055] like figure 1 As shown, this embodiment provides a single-axis tracking flexible photovoltaic support, which is arranged at both ends of each row of photovoltaic panels 7 to support flexible cables 6, and specifically includes a support body, which has two uprights 1, two diagonal braces 2. The beam 3 and the two oppositely arranged arc-shaped slide rails 41, each diagonal brace 2 is arranged on the outer side of the corresponding column 1, the beam 3 is connected between the tops of the two columns 1, and the two oppositely arranged arc-shaped slide rails 41. The rails 41 are arranged on the inner sides of the two uprights 1, and the arc-shaped slide rails 41 connect the uprights 1 and the beams 3 at the same time. The opposite sides of the two oppositely arranged arc-shaped slide rails 41 are pr...

Embodiment 3

[0060] This embodiment provides a photovoltaic power generation system, using two rows of the single-axis tracking flexible photovoltaic supports as described in Embodiment 1 or 2, such as Figure 5 Shown is a row of the single-axis tracking flexible photovoltaic supports. A flexible cable 6 is anchored between the opposite rotating beams 5 , and a plurality of photovoltaic panels 7 are arranged on the flexible cable 6 .

[0061] By using the above-mentioned single-axis tracking flexible photovoltaic support to anchor the flexible cables 6, and then support several photovoltaic panels 7, it can adapt to the fixation and balance between the flexible cables 6 and the column 1, and ensure the flexible cables of the flexible photovoltaic support. 6. The stability during the rotation process enables the photovoltaic panel 7 to be set to follow the sun to rotate under the drive of the flexible cable 6. Since the single-axis tracking function ensures the direct sunlight state, the pow...

Abstract

The invention relates to a single-axis tracking type flexible photovoltaic support and a photovoltaic power generation system. The single-shaft tracking type flexible photovoltaic support comprises a driving device and a support body which is vertically arranged. One side of the support body is fixedly connected with an arc-shaped sliding rail mechanism, a rotating cross beam is arranged on the arc-shaped sliding rail mechanism, the rotating cross beam is used for anchoring and supporting a flexible inhaul cable of a photovoltaic panel, the two ends of the rotating cross beam are supported on the arc-shaped sliding rail mechanism, and the driving device drives the rotating cross beam to rotate along the arc-shaped sliding rail mechanism. In the process that the photovoltaic panel rotates along with the sun, the two ends of the rotating cross beam are supported on the arc-shaped sliding rail mechanisms all the time and transmitted to the vertically-arranged support body, the rotating cross beam can adapt to fixation and balance between the flexible inhaul cable and the stand column, and the stability of the flexible inhaul cable of the flexible photovoltaic support in the rotating process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic, in particular to a single-axis tracking flexible photovoltaic support and a photovoltaic power generation system. Background technique [0002] Different from the traditional rigid support system, the traditional rigid support system can achieve single-point setting and small span setting, such as 5-6m span, but due to cost issues, it is difficult to achieve larger span settings, such as 20m span . The flexible photovoltaic support system uses flexible cables instead of rigid longitudinal beams to support photovoltaic panels, so it has the advantages of strong spanning ability, simple structure, less material consumption, short construction period, and lower investment. The adaptability of various terrains such as ravines is stronger, so it has been rapidly promoted and applied in the engineering field in the past two years. [0003] With the rapid development of the photovoltaic ind...
