Description

Technical Field

[0001] The present invention relates to the field of photovoltaic power generation devices, and in particular to a photovoltaic power generation device that utilizes natural wind to achieve automatic angle change. Background Art

[0002] In the event of insufficient sunlight, rainy days, or nighttime wind speed fluctuations, the photovoltaic power generation device will be unable to generate electricity and thus will be unable to power the motor. Currently, photovoltaic power generation uses either electrical energy or mechanical transmission angle-changing needles to achieve dynamic angle change, but both methods consume a large amount of grid power. Furthermore, both types of devices have high installation and maintenance costs, while their efficiency is relatively low. Strong winds or failures in any part of the equipment can cause immeasurable losses to the photovoltaic power generation device. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a photovoltaic power generation device that uses natural wind to achieve automatic angle change.

[0004] The technical solution adopted by the invention is: a photovoltaic power generation equipment that uses natural wind to achieve automatic angle change. The technical key points are that it includes two fixed supporting steel structures, and a photovoltaic panel matrix composed of multiple photovoltaic panels is connected between the two fixed supporting steel structures by steel wire ropes. The fixed steel structures use natural wind to adjust the wind shelter angle of the photovoltaic panel matrix.

[0005] In the above scheme, the fixed support steel member includes an electric pole, a steel beam, a main support rod and a slave support rod, the steel beam is hinged on the electric pole; the main support rod is composed of an upper support arm and a lower support arm hinged by a pin, the upper support arm is hinged to the lower end of the steel beam, and the lower support arm is hinged to one end of the support fixing clamp, and a torsion spring is also sleeved on the pin, one free end of the torsion spring is welded to the upper arm, and the other free end is welded to the lower arm, and the two free ends of the torsion spring form a V-shaped angle, and the V-shaped angle causes the upper arm and the lower arm to be hinged with the pin after being subjected to wind force. To unfold or fold the rotating axis; the slave support rod is composed of a supporting circular tube outer sleeve and a supporting circular tube inner sleeve, the supporting circular tube inner sleeve is sleeved in the supporting circular tube outer sleeve, one end of the supporting circular tube outer sleeve is hinged to the top of the steel beam, and one end of the supporting circular tube inner sleeve is hinged to the other end of the supporting fixed clamp; a spring is installed in the cavity where the supporting circular tube inner sleeve and the supporting circular tube outer sleeve are connected, and after the spring is subjected to the push-pull force of the supporting circular tube inner sleeve, the supporting circular tube inner sleeve moves in and out along the supporting circular tube outer sleeve, thereby changing the length of the slave support rod to adapt to the changes of the main support rod.

[0006] In the above solution, a connection hole for connecting a steel wire rope is provided on the steel beam.

[0007] In the above solution, the upper arm is hinged to the lower end of the steel beam through the ear plate, and the upper arm is hinged to the lower arm by using a pin shaft to pass through the pin hole on the third ear plate and the pin hole on the lower arm in sequence.

[0008] In the above scheme, when the main support rod is unfolded or folded by the action of wind, it generates a pulling force that drives one end of the steel beam to move. Under the action of the pulling force of the steel beam, the support rod causes the other end of the steel beam to move accordingly, so that the overall posture of the photovoltaic panel connected to the steel beam and fixed by a steel wire rope is adjusted.

[0009] In the above solution, the range of the wind shelter angle is 20 degrees to 36 degrees.

[0010] The beneficial effects of the present invention are as follows: the photovoltaic power generation equipment that uses natural wind to achieve automatic angle change uses a matching structure consisting of a main support rod and a slave support rod hinged on the steel beam to adjust the posture of the photovoltaic power generation panel. The two supports enable the steel beam and the photovoltaic power generation panel to change angles simultaneously within a wind shelter angle between 20 degrees and 36 degrees, thereby playing a role of natural angle change and wind shelter, greatly reducing damage to the photovoltaic power generation device caused by wind disasters and protecting the normal operation of the equipment.

DETAILED DESCRIPTION

[0017] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following Figures 1 to 4 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

[0018] This embodiment utilizes a photovoltaic power generation device that automatically adjusts its angle using natural wind. This device can automatically adjust its angle using natural wind when there is insufficient sunlight, on rainy days, or at night when there is a sudden change in wind speed. This embodiment utilizes two identical fixed support steel members, a first fixed support steel member 24 and a second fixed support steel member 25. Four transverse steel cables 6 are connected between these two fixed support members. Each transverse steel cable 6 has one free end connected to the first fixed support steel member 24 and the other free end connected to the second fixed support steel member 25. This embodiment utilizes a photovoltaic power generation device that automatically adjusts its angle using natural wind. This device can automatically adjust its angle using this device when there is insufficient sunlight, on rainy days, or at night when there is a sudden change in wind speed. This embodiment utilizes two identical fixed support steel members, a first fixed support steel member 23 and a second fixed support steel member 24. Four transverse steel cables 6 are connected between these two fixed support members. Each transverse steel cable 6 has one free end connected to the first fixed support steel member 23 and the other free end connected to the second fixed support steel member 24. This embodiment also utilizes the strong tensile strength, flexibility, and high load-bearing properties of steel wire ropes to connect multiple photovoltaic panels 3 to steel wire ropes 6. The photovoltaic panels 3 are secured to the steel wire ropes via steel wire rope clips 5. In this embodiment, the photovoltaic panels 3 are connected via steel wire ropes 6 to form a two-row, sixteen-column photovoltaic panel matrix. The photovoltaic panels in the first row are connected via two upper steel wire ropes, while the photovoltaic panels in the second row are connected via two lower steel wire ropes.

[0019] The two fixed support steel members 24 and 25 in this embodiment are respectively fixed by a pull drum 21 located below the ground. The two fixed support steel members have the same structure, respectively including a steel beam 1, an electric pole 10, a main support pole formed by an upper support arm 14 and a lower support arm 15 hinged together, and a secondary support pole formed by a supporting circular tube outer sleeve 19 and a supporting circular tube inner sleeve 18, wherein the electric pole 10 is an annular concrete electric pole that can be fixed on ordinary ground or on frozen ground as needed. In this embodiment, a first ear plate 4 is provided on the steel beam 1, and a second ear plate 8 is provided on the top of the electric pole 10. The pin 7 passes through the first ear plate 4 and the second ear plate 8 to connect the steel beam 1 to the electric pole 10, and the steel beam 1 can swing around the pin 7. A grounded lightning conductor 22 is connected to the bottom of the electric pole 10.

[0020] In this embodiment, a connection hole for connecting the steel wire rope 6 is provided on the steel beam 1. The steel wire rope 6 is secured by installing it in the connection hole using a tensioning device. The upper arm 14 is hinged to the lower end of the steel beam 1 via an ear plate. A pin passes through the pin hole in the third ear plate 12 and the pin hole in the lower arm 15, connecting the upper arm 14 to the lower arm 15. The lower arm 15 is hinged to one end of the support clamp via the fourth ear plate 16. A torsion spring 13 is also sleeved on the pin. One free end of the torsion spring 13 is welded to the upper arm 12, and the other free end is welded to the lower arm 15. The two free ends of the torsion spring 13 form a V-shaped angle. When subjected to wind force, the V-shaped angle allows the upper arm 12 and the lower arm 15 to expand or collapse around the pin.

[0021] In this embodiment, the supporting circular tube inner sleeve 18, which constitutes the slave support rod, is sleeved within the supporting circular tube outer sleeve 19. One end of the supporting circular tube outer sleeve 19 is hinged to the top of the steel beam 1, and the other end of the supporting circular tube inner sleeve 18 is hinged to the support fixing clamp 17. In this embodiment, the supporting circular tube inner sleeve 18 can move along the inner cavity of the supporting circular tube outer sleeve 19, thereby changing the overall length of the slave support rod. A spring 20 is installed within the cavity connecting the supporting circular tube inner sleeve 18 and the supporting circular tube outer sleeve 19. When the spring 20 is squeezed by the supporting circular tube inner sleeve 18, the spring force causes the supporting circular tube inner sleeve 18 to move in and out of the supporting circular tube outer sleeve 19, changing the length of the slave support rod. The slave support rod changes with the main support rod structure, and the two work together to adjust the posture of the photovoltaic panel 6 within a windproof angle range. In this embodiment, the angle formed between the photovoltaic panel 3 and the horizontal ground is referred to as the windproof angle 11, which ranges from 20 degrees to 36 degrees. Under normal conditions, the angle of the photovoltaic panels remains unchanged at a wind-proof angle of 36 degrees.

[0022] In this embodiment, the photovoltaic panel matrix is ​​formed, with each row of photovoltaic panels 3 secured by a wire rope bracket 2. In this embodiment, a supporting wire rope bracket 2 is installed on each of the fifth and sixth rows of photovoltaic panels, and on each of the twelfth and fifteenth rows. Users can customize the installation according to their needs. The two wire rope brackets 2 in this embodiment also connect to wire rope cables, which are connected to the stabilizing and balancing block 9 via wire rope clips 5.

[0023] The photovoltaic power generation equipment in this embodiment can automatically change the angle of the steel structure by natural wind. The working principle is as follows:

[0024] First, use steel wire ropes to install each photovoltaic panel between two fixed supporting steel members. Under normal wind conditions, the photovoltaic panels maintain a constant angle of 36 degrees. When the wind exceeds normal conditions, the photovoltaic panels will generate resistance to the wind according to the strength of the wind. The stronger the wind, the greater the resistance. The main support rods and the secondary support rods will swing with the natural wind, driving the photovoltaic panels and the stable balance block to automatically generate the best wind shelter angle according to the wind resistance. The photovoltaic panels of this embodiment change angles between 36 degrees and 20 degrees, playing a role of natural angle change to avoid wind, greatly reducing the damage to the photovoltaic power generation device caused by wind disasters and protecting the normal operation of the equipment.

[0025] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
