Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to an anti-wind photovoltaic bracket. Background Art

[0002] As an important way to produce clean energy, the installed capacity of photovoltaic power generation has expanded rapidly in recent years. In high-altitude areas, the air density is relatively low, the light resources are rich, the population density is low, and the land resources are rich, which are suitable for the development and construction of photovoltaic projects. In some provinces (such as Yunnan Province) to reduce the impact of photovoltaic construction on the original surface vegetation, it is stipulated that the minimum distance from the ground of the photovoltaic panel must reach a certain height (2.5m in Yunnan Province). At present, the conventional brackets used in photovoltaic projects generally cannot adjust the height and the inclination angle of the components. In the case of strong wind speed, problems such as the photovoltaic panel being blown off, the bracket being deformed, the bracket foundation being fractured, and the components being damaged are likely to occur in the existing brackets.

[0003] The Chinese invention patent with the publication number of CN118363403A discloses an anti-wind control method and device for a photovoltaic bracket array and a photovoltaic bracket array system. The photovoltaic bracket array includes multiple rows of photovoltaic brackets, each row of photovoltaic brackets includes a guide rail and multiple photovoltaic brackets, and each photovoltaic bracket includes a photovoltaic panel. Light sensors are installed on the top side and the bottom side of the front surface of the photovoltaic panel. The anti-wind control method includes: obtaining the current wind speed of the environment where the photovoltaic bracket array is located; when the current wind speed is less than the preset wind speed, detecting the light signals of the light sensors of each photovoltaic bracket; for any one photovoltaic bracket, if the light signals of two corresponding light sensors are not detected simultaneously, controlling the distance between the photovoltaic bracket and the adjacent photovoltaic bracket in the front side to continuously increase until the light signals of two corresponding light sensors are detected simultaneously. The problem is that since multiple sensors are used to provide adjustment support, the adjustment is relatively complex. Although the above adjustment method can adjust the height and inclination angle of the photovoltaic bracket when the wind is strong and reset when the wind is weak, because the wind is invisible, it may cause the photovoltaic bracket to be in an adjustment state all the time, which is rather uneconomical.

In actual use, the support frame 1 is used to install the photovoltaic panel. Both the height adjustment mechanism 2 and the inclination adjustment mechanism 3 are connected to the support frame 1. The height adjustment mechanism 2 is used to adjust the height of the support frame 1, and the inclination adjustment mechanism 3 is used to adjust the inclination of the support frame 1. When adjusting the inclination of the support frame 1, the first electrically controlled telescopic connecting rod 4 needs to move on the chute 5 to achieve the inclination adjustment of the support frame 1.

[0032] In this embodiment, the control host uses an MSP430 single-chip microcomputer. During actual use, the MSP430 single-chip microcomputer has the advantages of stable operation, low power consumption, and good expansion performance. Using the MSP430 single-chip microcomputer as the control host can achieve long-term stable operation.

[0035] In this embodiment, the telescopic device 22 includes an electric cylinder 221 and a telescopic rod 222, and the electric cylinder 221 is drivingly connected to the telescopic rod 222. In actual use, the electric cylinder 221 is used to drive the telescopic rod 222 to move up and down. When the telescopic rod 222 moves up and down, the height of the height adjustment mechanism 2 changes, thereby realizing the height adjustment of the photovoltaic panel.

[0036] In this embodiment, the inclination angle adjustment mechanism 3 further includes a second electrically controlled telescopic connecting rod 7.

[0037] In this embodiment, the sliding locking assembly 6 includes a slider 61 and a locking device 62. The locking device 62 is installed on the slider 61.

[0038] In this embodiment, the locking device 62 includes an electric lock body 621 and a lock tongue 622, and the electric lock body 621 is drivingly connected to the lock tongue 622. In actual use, the electric lock body 621 realizes the locking of the slider 61 by driving the lock tongue 622 to extend outward. At the same time, the electric lock body 621 can facilitate the free movement of the slider 61 by driving the lock tongue 622 to contract inward.

[0039] In this embodiment, the chute 5 is provided with a fixing hole 51 for the lock tongue 622 to pass through corresponding to the lock tongue 622. In actual use, by providing the fixing hole 51 on the chute 5, when the lock tongue 622 extends outward, the lock tongue 622 can pass through the fixing hole 51, so that the locking device 62 and the first electrically controlled telescopic connecting rod 4 installed on the locking device 62 cannot move freely, realizing fixation.
