Description

Technical Field

[0001] The invention relates to the field of photovoltaic systems, and in particular to a split-type rotating light-chasing photovoltaic system for a wind power tower. Background Art

[0002] As global energy demand continues to grow, the use of renewable energy sources such as solar energy and wind energy has gradually become an important direction for global energy development. As one of the core technologies for the use of solar energy, photovoltaic power generation systems have been widely used in many application fields. However, most traditional photovoltaic systems use fixed installation methods and cannot dynamically track the sun as the position of the sun changes, resulting in the inability to maximize the power generation efficiency of photovoltaic panels. At the same time, since most photovoltaic systems exist independently of wind power generation systems, resource utilization efficiency is low, and it is impossible to achieve an effective combination of wind energy and light energy.

[0003] For example, CN102929294A discloses a wind-solar complementary street lamp power supply based on intelligent solar panel tracking, which aims to provide a system that can automatically track the position of the sun, improve the utilization efficiency of solar panels, and increase the power generation by about 40% compared with fixed photovoltaic systems, greatly increasing the total power generation, and combining solar power generation with wind power generation for road lighting systems. The key points of its technical solution include a support frame 12, a steering mechanism, a tilting mechanism, a solar panel assembly, a position acquisition module and a data processing module 19, an installation platform 24, a wind turbine generator set and a weather vane 28.

[0005] In view of the above technical problems, it is of great significance to propose a photovoltaic system that can be combined with a wind turbine tower, has strong protection performance and can rotate flexibly. Especially in the application of wind-solar hybrid power generation system, a reasonably designed photovoltaic system can not only make full use of solar energy resources, but also work in coordination with wind power generation to further improve the comprehensive energy utilization efficiency of the system.

[0067] In combination with the above preferred implementation, this embodiment provides a more specific implementation, such as Figures 1 to 10 As shown, including:

[0068] A split rotating sun-chasing photovoltaic system for a wind turbine tower. The system uses a modular design and is combined with a wind turbine tower to achieve efficient power generation of photovoltaic panels and optimize the convenience of installation, maintenance and replacement of the system. The invention also solves the problem that traditional photovoltaic systems are difficult to adapt to complex installation environments, and through rotating components, photovoltaic panels can follow the trajectory of the sun all day long to achieve optimal power generation efficiency.

[0069] like Figure 1 As shown, the system includes a wind turbine tower 100, a load-bearing assembly 200, a rotating assembly 300, a protection assembly 400, a support assembly 500 and a photovoltaic assembly 600. The components are closely matched, the system is fixedly connected to the wind turbine tower through the load-bearing assembly 200, and the photovoltaic panel is rotated 360 degrees through the rotating assembly 300, thereby maximizing the use of solar energy for power generation.

[0070] like Figure 2 As shown, the load-bearing assembly 200 adopts a split structure, consisting of a first load-bearing member 210 and a second load-bearing member 220, which are fastened together by bolts and nuts to ensure structural stability. The first load-bearing member is connected to the wind power tower 100, and the second load-bearing member is installed under the first load-bearing member and fixed by additional bolts to support the weight of the entire system. The load-bearing assembly is made of high-strength metal, which can maintain structural strength in the harsh environment of the wind power tower and prevent deformation caused by long-term use.

[0071] In order to enhance the wind resistance of the system, the load-bearing components are made of alloy steel with a thickness of 10-15 mm, and the surface is treated with anti-corrosion to adapt to different climatic conditions. Bolts and nuts are made of stainless steel to prevent oxidation and rust. In addition, the first load-bearing member 210 and the second load-bearing member 220 are designed with a groove structure to better adapt to the cylindrical structure of the tower, and the fasteners are used to ensure a stable connection in the radial and axial directions.

[0072] like Figure 3 and Figure 4 As shown, the rotating assembly 300 mainly includes a first supporting rail 310, a second supporting rail 320, a plurality of tapered rollers 330, a retaining frame 340, six motors A350, and six tapered gears 360. The first supporting rail is mounted on the load-bearing assembly 200, and the second supporting rail is higher than the first supporting rail and rotates through a plurality of tapered rollers. The rollers are evenly distributed between the supporting rails and connected through the retaining frame 340, so that the system can achieve 360-degree free rotation in the horizontal direction.

[0073] The tapered roller 330 is made of high-strength steel and coated with a wear-resistant layer to ensure good rolling performance during long-term operation. The roller has a diameter of 50 mm and can withstand large radial and axial loads to ensure smooth rotation. The cage 340 is not only connected by a split snap-on connection of the tongue 341 and the groove 342 to ensure easy installation, but also bears part of the load of the support frame 510. Therefore, the cage is made of high-strength alloy material to ensure its strength and stability during long-term load-bearing and rotation.

[0074] like Figure 5 As shown, six pairs of mounting seats (470) are evenly distributed inside the first motor protection cover 410, and six motors B (350) are respectively installed on each mounting seat by bolt connection. The upper part of each retaining frame 340 is a circle of conical gear ring 343, which meshes with the conical gear 360. The conical gear is installed on the output shaft of the motor A350 through a key connection, thereby driving the free rotation of the retaining frame 340.

[0075] The rotating assembly can maintain good rotation performance under high wind speed conditions. Through the cooperation of the slide rail and the roller, the system can accurately adjust the angle of the photovoltaic panel according to the position of the sun to ensure maximum absorption of solar energy at all times.

[0076] like Figure 6As shown, the protection assembly 400 is composed of a first protection cover 410 and a second protection cover 420. The protection cover is fixed by bolts and nuts and is enclosed on the outside of the rotating assembly 300 to prevent dust and moisture from entering the system and ensure the durability of the system. Two layers of hot-melt elastic rubber rings 430 are embedded inside the protection cover. The rubber rings have good elasticity and sealing properties, and can still keep the inside of the system clean and dry when the support rod passes through. It is worth noting that the hot-melt elastic rubber ring is installed in a split manner through its hot-melt characteristics, so that the rubber ring can fit perfectly with the protection cover after installation, providing an excellent sealing effect.

[0077] The protective cover is made of corrosion-resistant aluminum alloy, and the rubber ring is made of high-temperature resistant silicone material. It can work normally in the temperature range of -40℃ to 80℃ and adapt to extreme climate conditions. The 460° gap reserved in the middle can ensure the free movement of the support rod, while preventing foreign substances from entering the system, enhancing the overall protection performance.

[0078] like Figure 7 and Figure 8 As shown, the support assembly 500 includes three sets of support frames 510, four sets of rotating rods 520, photovoltaic panel brackets 530, support beams 540, diagonal braces 580, and adjustment motors 5180. The support frames are fixed to the retaining frame 340 by bolts. The retaining frame needs to bear part of the load of the support frame, so it uses high-strength alloy materials to ensure that it will not deform during long-term operation.

[0079] The supporting beam 540 is connected to the supporting frame via a C-shaped clamp 550 , and the photovoltaic panel bracket 530 is installed on the rotating rod 520 to achieve angle adjustment of the photovoltaic panel.

[0080] The support frame 510 adopts a triangular structure design to enhance the stability of the system. The support beam 540 is made of aluminum alloy, which is lightweight and strong and can bear the weight of the photovoltaic panel. The rotating rod 520 is connected to the supporting beam through the latch 590. The adjustment motor 5180 is fixed to the beam through screw connection. The latch 590 drives the rotating rod group to rotate, so that the rotating rod group can rotate freely on the clamp 570, so that the tilt angle of the photovoltaic panel can be flexibly adjusted to achieve the best power generation efficiency.

[0081] The main beam 510a and the supporting beam 510b of the support frame are fixed to the connection base 5130 by bolts to achieve multi-point support, thereby further improving the wind resistance of the system.

[0082] During the actual installation process, the load-bearing assembly is first fixed to the wind turbine tower 100. Then, the rotating assembly is bolted to the load-bearing assembly 200 to ensure that it can rotate flexibly. Next, the supporting assembly is installed on the rotating assembly through the retaining frame, and the rotating rod 520 and the photovoltaic panel bracket 530 are adjusted to enable the photovoltaic panel to be at a suitable angle. After the system is installed, the rotating assembly will automatically adjust the angle of the photovoltaic panel according to the position of the sun to ensure maximum absorption of solar energy.

[0083] like Fig. 9 As shown, the photovoltaic assembly 600 is composed of six solar panels 610 and their corresponding storage batteries 620. The solar panels are fixed to the photovoltaic bracket by bolts. The solar panels are made of high-efficiency single-crystal silicon material and have high photoelectric conversion efficiency. The storage batteries are used to store the electricity generated by the photovoltaic system.

[0084] Each photovoltaic panel is 2 meters by 1 meter in size, which can provide a large area of ​​solar energy absorption. The battery is a lithium battery with the characteristics of long life and high energy density. It can store electricity during the day and release it at night or on cloudy days, realizing a wind-solar complementary power generation method. Fig.10 The overall schematic diagram of the system's photovoltaic panels installed on a wind turbine tower is shown. The rotating assembly enables the photovoltaic panels to rotate around the tower, ensuring that the photovoltaic panels are facing the sun at the best angle at all times.

[0085] The photovoltaic system provided in this embodiment combines wind energy and solar energy to achieve higher power generation efficiency, reduce energy loss, and effectively reduce overall operating costs; it uses high-strength materials, such as high-strength steel, combined with sophisticated protection design to ensure its long-term stability and durability in harsh environments. The protection design of the system also ensures the stable operation of the equipment in harsh environments and is widely used in wind farms and similar environments. In addition, the split component design greatly facilitates the installation, maintenance and disassembly of the equipment, making on-site operations more efficient, enhancing the adaptability and service life of the system, and reducing maintenance costs and time. The flexibility of the system makes it not only suitable for wind power towers, but can also be expanded to communication towers, meteorological towers, urban buildings and other fields. It has broad market prospects and is in line with the concept of sustainable development.

[0086] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
