Description

Technical Field

[0001] The invention relates to the technical field of renewable clean energy, and in particular to a wind energy and solar energy coupling airfoil vertical axis wind turbine. Background Art

[0002] Wind energy and solar energy are clean and renewable energy sources that are widely present in nature and are inexhaustible. At present, the types of wind turbines that use wind energy on the market are mainly horizontal axis wind turbines. This type of wind power generation technology is mature, but it has the characteristics of relatively complex structure, high starting wind speed requirements, navigation devices, and high manufacturing costs. The use of solar energy for power generation is also relatively mature in technology, mainly hard plate-shaped panels, but there is a kind of flexible solar panel that is an emerging technology product in the world's solar energy industry. It is a solar panel made of resin-encapsulated amorphous silicon as the main photovoltaic element layer flat on a base made of flexible material. It can be bent and folded, but the efficiency is low. The structure of the comprehensive utilization of wind energy and solar energy is also diverse, usually a combination of solar panels on the upper, lower and surrounding parts of the wind turbine. The utilization of wind energy and solar energy has independent energy systems. This combination form is characterized by a large footprint and a low degree of energy coupling utilization. How to achieve the gain of wind energy and solar energy coupling utilization requires a new technical solution for wind energy and solar energy utilization. Summary of the invention

[0003] In order to address the deficiencies in the prior art, the present invention discloses a wind-solar energy coupled airfoil vertical axis wind turbine, which combines a flexible solar panel with a new type of resistance-type blade. It has the characteristics of simple structure, low wind speed start-up, small size, low noise, etc. At the same time, the wind turbines can be arranged in clusters, which can improve the comprehensive utilization efficiency of wind energy and solar energy.

[0004] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme:

[0005] A wind-solar coupled airfoil vertical axis wind turbine. The device consists of a new type of resistance blade, a flexible solar panel, a rotating conductive slip ring, a disc generator, a coupling, an encoder, a solar motor, an energy collection controller, an energy storage device, a control cabinet, a fixed flange, a fixed bracket, etc. The wind turbine adopts a three-blade or multi-blade form. The new type of resistance blade is an arc-shaped structure that is narrow at the top and wide at the bottom. The lower end of the blade is a circular bottom plate that plays a supporting and wind gathering role, forming a structure similar to a truncated cone to increase the wind receiving area; the blade material is made of light alloy or transparent material, and the whole presents a certain taper to increase the area covered by the flexible solar panel.

[0006] The flexible solar panel is a well-known solar panel technology product. It is a solar panel made of resin-encapsulated amorphous silicon as the main photovoltaic element layer laid flat on a base plate made of flexible material. Flexible solar panels, such as Sunpower's solar panels, have a higher conversion efficiency than single and polycrystalline ones, and their curvature can reach 15°-30°. A coupling relationship is established between the flexible solar panel and the new resistance-type blade. When the flexible solar panel is attached to the inner layer of the resistance-type blade, the resistance-type blade is made of transparent material, which can allow sunlight to penetrate; when the flexible solar panel is attached to the outer layer of the resistance-type blade, the blade material can be made of a lightweight alloy material with good heat dissipation performance. The truncated cone-like structure of the wind-solar energy coupled airfoil wind turbine rotates and has a certain tilt angle at the same time, realizing full-angle lighting of the solar panel.

[0007] The rotating conductive slip ring is an electrical component that connects the rotating body, transmits energy and signals, and makes it possible to successfully combine the power generated by the wind turbine and the flexible solar panel. The power of the flexible solar panel passes through the wire hole of the bottom plate of the wind turbine blade through the cable, and is connected to the rotating end of the rotating conductive slip ring, so that the power generated by the flexible solar panel is transmitted. The cable of the flexible solar panel integrated into the wind turbine blade will not be entangled with the wind turbine rotation. The rotating end of the rotating conductive slip ring is connected to the wind turbine shaft, and the fixed end is connected to the cable of the control cabinet.

[0008] The disk generator is fixed at the lower position of the wind turbine, and the wind turbine shaft is directly connected to the input shaft of the disk generator through a coupling, without an intermediate transmission link, that is, the wind turbine directly drives the disk generator to generate electricity, and the generator is connected to the fixed bracket through a fixed flange. The encoder is built into the disk motor to collect the rotation speed of the blades. The collected signal is given by the pulse signal of the encoder and fed back to the control cabinet to realize real-time monitoring of the operation status of the wind turbine.

[0009] The control cabinet is provided with an energy collection controller and an energy storage device. The energy collection controller includes control modules of a disc generator and a flexible solar panel, which rectifies and transforms the electricity output by the generator, and comprehensively collects and manages the electricity output by the flexible solar panel. The energy storage device uses a lead-acid battery with a relatively high operating voltage, a wide temperature range and good discharge performance to store the electricity generated by the wind generator and the flexible solar panel.

[0010] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0011] 1. The present invention discloses a wind-solar energy coupling airfoil vertical axis wind turbine, which adopts a novel upper narrow and lower wide arc-shaped resistance blade, and the lower end of the blade is a circular bottom plate for supporting and gathering wind, and has the characteristics of simple structure, low cost, no need for yaw device, low wind speed operation, etc.

[0012] 2. The present invention discloses a wind-solar energy coupled airfoil vertical axis wind turbine, which adopts a flexible solar panel attached to the inner layer or outer layer of a new type of resistance-type blade, and utilizes rotating arc-shaped blades to collect energy from full-angle sunlight, and has the advantages of good heat dissipation effect, large illumination area, high conversion efficiency, and sustainability;

[0013] 3. The present invention discloses a wind-solar energy coupled airfoil vertical axis wind turbine, which couples a new type of resistance blade with a flexible solar panel to establish an energy utilization device with a wind-solar energy coupling relationship. Compared with the traditional combined wind-solar energy utilization device, the wind-solar energy coupled vertical axis wind turbine has the advantage of comprehensive utilization of wind and solar energy.
