Description

Technical Field

[0001] This invention relates to the field of photovoltaic support technology, and in particular to a tracking photovoltaic support. Background Technology

[0002] Tracking photovoltaic (PV) brackets are intelligent PV support systems that can adjust their angle in real time to follow changes in the sun's position. Unlike traditional fixed brackets, they are driven by a motor, ensuring that the PV modules always face the sun at a near-vertical angle, like a sunflower.

[0003] The system is mainly divided into two categories: single-axis tracking (usually rotating horizontally along the east-west direction) and dual-axis tracking (which can adjust both azimuth and tilt angles simultaneously). Its core lies in maximizing the effective sunshine duration of the modules through algorithmic control, thereby significantly improving power generation efficiency.

[0004] Compared to fixed mounting systems, tracking mounting systems can typically increase power generation by 15% to 30%, and are particularly suitable for large ground-mounted power plants with high direct sunlight ratios and flat, open terrain. Although their initial investment and subsequent maintenance costs are higher, the increased power generation revenue makes them more economical over their entire life cycle, making them one of the key technologies for reducing costs and increasing efficiency in photovoltaic power plants.

[0005] Existing photovoltaic (PV) mounting systems are largely installed in deserts, grasslands, and at sea, where strong winds are common and can damage PV facilities. Summary of the Invention

[0006] To overcome the technical defects of existing technologies, this invention provides a tracking photovoltaic bracket to prevent damage to the photovoltaic system.

[0007] The technical solution adopted in this invention is:

[0008] A tracking photovoltaic (PV) bracket includes a PV system, a rotating system, a flipping system, a base, a pneumatic system, an elastic friction device, and an elastic torsion system. The rotating system is rotatably mounted on the base with a vertical rotation axis. The flipping system is mounted on the rotating system with a horizontal rotation axis and has two flipping output ends. The elastic torsion system is mounted on each flipping output end of the flipping system. The pneumatic system is slidably mounted on the PV system. The elastic torsion system includes a locking shaft and a torsion spring. The PV system is mounted on the locking shaft, which is rotatably mounted on each flipping output end of the flipping system. The two ends of the torsion spring are installed between the locking shaft and the flipping output ends. A locking cylinder is provided on the locking shaft, with its output end pointing towards the flipping output end. When the pneumatic system slides along the PV system, the area of ​​the PV system at both ends of the flipping output end is different. The PV system, with the flipping axis of the flipping output end as the boundary, has an area on the side with the pneumatic system that is larger than the area on the side without the pneumatic system. The elastic friction device is mounted on the flipping system and rubs against the locking shaft.

[0009] Preferably, the photovoltaic system includes a photovoltaic beam, an adjustment bracket, and a photovoltaic support plate. The photovoltaic beam is mounted on a locking shaft, the adjustment bracket is mounted on the photovoltaic beam, and the photovoltaic support plate is mounted on the adjustment bracket.

[0010] Preferably, the adjusting bracket is provided with a position adjusting groove, and the photovoltaic support plate is installed in the position adjusting groove by bolts and pressure plates.

[0011] Preferably, the rotary system includes a rotary housing, a rotary motor, a rotary worm wheel, and a rotary worm. The rotary worm wheel is rotatably mounted on the rotary housing, the rotary housing is mounted on a base, the rotary motor is mounted inside the rotary housing, the rotary worm is mounted on the output end of the rotary motor, the rotary worm wheel and the rotary worm mesh, and the tilting system is mounted on the rotary worm wheel.

[0012] Preferably, the flipping system includes a flipping housing, a flipping motor, a flipping worm wheel, and a flipping worm. The flipping worm wheel is rotatably mounted on the flipping housing, the flipping housing is mounted on a rotary system, the flipping motor is mounted inside the flipping housing, the flipping worm is mounted on the output end of the flipping motor, the flipping worm wheel and the flipping worm mesh, the elastic friction device is mounted on the flipping housing, the photovoltaic system is mounted on a locking shaft, the locking shaft is rotatably mounted on the flipping housing, the two ends of the torsion spring are mounted between the locking shaft and the flipping worm wheel, and the two sides of the flipping worm wheel form flipping output ends.

[0013] Preferably, the wind-driven system includes a wind-driven plate, a wind-driven slide bar, and a wind-driven return spring. The wind-driven plate is provided with a wind-driven plate, the wind-driven slide bar is slidably installed at the bottom of the photovoltaic system, and the two ends of the wind-driven return spring are respectively pressed between the wind-driven slide bar and the wind-driven plate.

[0014] Preferably, the area of ​​the wind turbine blade is greater than 0.1 square meters.

[0015] Preferably, the elastic friction device includes a friction plate and a friction spring. The friction plate is mounted on the friction spring, which is mounted on the tilting system. The friction plate presses against the locking shaft of the elastic torsion system. The pressing direction of the friction spring points towards the locking shaft. The tilting worm gear has a guide post for the friction plate to slide on.

[0016] The beneficial effects of this invention are:

[0017] The slewing system is rotatably mounted on the base, with its rotation axis vertical, enabling the photovoltaic system to rotate. The flipping system is mounted on the slewing system, enabling the photovoltaic system to flip. The rotation axis of the flipping system is horizontal, and the flipping system has two flipping output ends, facilitating the installation of photovoltaic systems with larger areas. The elastic torsion system is mounted on each flipping output end of the flipping system. The wind-driven system is slidably mounted on the photovoltaic system. In strong winds, the wind-driven system is pulled out by the wind force. The pulled-out wind-driven system on the photovoltaic system generates a deflection torque due to the wind force, causing the photovoltaic system to deflect against the torque of the elastic torsion system and the friction force of the elastic friction device. The deflection of the wind-driven system makes the direction of the photovoltaic system dynamically approach parallel to the wind direction, preventing the photovoltaic system from being damaged by flying sand and stones in strong winds.

[0018] The elastic torsion system includes a locking shaft and a torsion spring. The photovoltaic system is mounted on the locking shaft, which is rotatably mounted on each flipping output end of the flipping system. The two ends of the torsion spring are installed between the locking shaft and the flipping output ends. A locking cylinder is provided on the locking shaft, with its output end pointing towards the flipping output end. When the wind force is low, the locking cylinder extends, its output end pressing against the flipping output end, thus locking the locking shaft and the flipping output end. This allows the photovoltaic system to rotate precisely even in low wind conditions. When the wind-driven system slides along the photovoltaic system, the photovoltaic system rotates on both sides of the flipping axis at the flipping output end. The areas are different, meaning that the photovoltaic system, with the flipping axis of the flipping output end as the boundary, has a larger area on the side with the wind-driven system than on the side without the wind-driven system. The elastic friction device is installed on the flipping system, and the elastic friction device rubs against the locking shaft. When the wind is strong, the wind-driven system is deflected by the wind force, so that the direction of the photovoltaic system is dynamically consistent with the wind direction. However, since the wind direction may fluctuate, the wind-driven system may sway. The elastic friction device is used to absorb energy when the wind-driven system sways, stabilize the attitude of the photovoltaic system, prevent the photovoltaic system from going out of control, and prevent damage to the photovoltaic system.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figure 1 — Figure 6As shown, this embodiment provides a tracking photovoltaic (PV) bracket, including a PV system 1, a rotation system 2, a flipping system 3, a base 4, a wind-driven system 5, an elastic friction device 7, and an elastic torsion system 6. The rotation system 2 is rotatably mounted on the base 4, and its rotation axis is vertical, enabling the PV system 1 to rotate. The flipping system 3 is mounted on the rotation system 2, enabling the PV system 1 to flip. The rotation axis of the flipping system 3 is horizontal, and the flipping system 3 has two flipping output ends, facilitating the installation of a larger area of ​​the PV system 1. The elastic torsion system... System 6 is installed on each flip output end of flip system 3, and wind system 5 is slidably installed on photovoltaic system 1. When the wind is strong, wind system 5 is pulled out under the action of wind force. The pulled-out wind system 5 on photovoltaic system 1 is blown by the wind and generates a deflection torque, which drives photovoltaic system 1 to overcome the torque of elastic torsion system 6 and the friction of elastic friction device 7. The deflection of wind system 5 makes the direction of photovoltaic system 1 dynamically approach parallel to the wind direction, avoiding photovoltaic system 1 from being damaged by flying sand and stones when facing the wind in strong wind.

[0035] The elastic torsion system 6 includes a locking shaft 61 and a torsion spring 63.

The two ends of the torsion spring 63 are installed between the locking shaft 61 and the flip output ends. A locking cylinder 62 is provided on the locking shaft 61, with its output end pointing towards the flip output end. When the wind force is low, the locking cylinder 62 extends, and its output end presses against the flip output end, locking the locking shaft 61 and the flip output end. This allows the photovoltaic system 1 to rotate precisely when the wind force is low. When the wind-driven system 5 slides along the photovoltaic system 1, the photovoltaic system 1 is at the flip output end. The areas on both sides of the flip axis are different. That is to say, the area of ​​the photovoltaic system 1 with the wind-driven system 5 is larger than the area of ​​the side without the wind-driven system 5, with the flip axis of the flip output end as the boundary. The elastic friction device 7 is installed on the flip system 3. The elastic friction device 7 rubs against the locking shaft 61. When the wind is strong, the wind-driven system 5 is deflected by the wind force, so that the direction of the photovoltaic system 1 is dynamically consistent with the wind direction. However, since the wind direction may fluctuate, the wind-driven system 5 may swing. The elastic friction device 7 is used to absorb energy when the wind-driven system 5 swings, stabilize the attitude of the photovoltaic system 1, prevent the photovoltaic system 1 from going out of control, and prevent the photovoltaic system 1 from being damaged.

The two ends of the torsion spring 63 are mounted between the locking shaft 61 and the flipping worm wheel 33 to limit the swing angle of the locking shaft 61 and prevent the photovoltaic system 1 from swinging excessively and being damaged. The two sides of the flipping worm wheel 33 form the flipping output end of the flipping system 3. The operation of the flipping motor 32 realizes the flipping of the photovoltaic system 1.

[0040] Specifically, the wind-driven system 5 includes a wind-driven plate 51, a wind-driven slide bar 52, and a wind-driven return spring 53. The wind-driven plate 51 is provided with a wind-driven piece 511. The wind-driven slide bar 52 is slidably installed at the bottom of the photovoltaic system 1. The two ends of the wind-driven return spring 53 are pressed between the wind-driven slide bar 52 and the wind-driven plate 51, respectively, so as to realize the automatic extraction of the wind-driven piece 511 when the wind is strong.

[0041] Specifically, the wind-driven plate 511 has an area greater than 0.1 square meters, providing additional power for the deflection of the photovoltaic system 1 in the wind.

[0042] Specifically, the elastic friction device 7 includes a friction plate 71 and a friction spring 72. The friction plate 71 is mounted on the friction spring 72, which is mounted on the flipping system 3. The friction plate 71 presses against the locking shaft 61 of the elastic torsion system 6. The pressing direction of the friction spring 72 points towards the locking shaft 61. In order to maintain the posture of the friction plate 71, the flipping worm gear 33 has a prismatic guide post for the friction plate 71 to slide. The friction plate 71 rubs against the locking shaft 61 to absorb mechanical energy and prevent the photovoltaic system 1 from going out of control with the wind.
