Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation, and particularly relates to an array chain type wind-solar dual-energy power generation system. Background Art

[0002] Existing photovoltaic power generation devices have a large floor area for photovoltaic power generation, which is inconvenient for popular use. The three-blade horizontal axis wind power generation device cannot be installed in densely populated areas. The vertical axis wind power generation device is too small in scale, and a single small wind power generation device cannot meet the power consumption requirements. Using multiple small wind power generation devices has too high equipment costs. Patent CN 110410274 A discloses a row-connected vertical axis wind power generation device, which uses a chain to connect multiple groups of blades. However, it has the following problems: Its working principle of sprocket drive has defects. The meshing of the sprockets at both ends with the chain is reasonable, but the meshing wrap angle of the sprocket in the middle with the chain is too small, violating the basic requirements of chain drive. The more wind impellers are connected, the more kinetic energy is lost; in actual application, it will directly fail and cannot transmit kinetic energy. Since the chain and the sprocket are in a meshing relationship, if this driven sprocket can not transmit kinetic energy when its rotational speed is greater than that of the driving sprocket, then similarly, when the rotational speed of the driving sprocket is greater than that of the driven sprocket, the meshing relationship between the chain and the sprocket will also be damaged, thus unable to normally transmit kinetic energy and unable to be used normally. Summary of the Invention

[0003] In view of the above problems, the present invention adopts an array chain type wind-solar dual-energy power generation system.

[0004] The present invention adopts the following technical solutions:

[0005] An array chain type wind-solar dual-energy power generation system includes a multi-stage air guide cylinder type vertical axis wind wheel, a chain transmission mechanism, a generator, a storage battery, a control system, and a photovoltaic panel; the generator is connected to the output end of the first-stage air guide cylinder type vertical axis wind wheel. The first-stage air guide cylinder type vertical axis wind wheel is connected to multiple second-stage air guide cylinder type vertical axis wind wheels through a first-stage chain transmission mechanism. The second-stage air guide cylinder type vertical axis wind wheel is connected to multiple third-stage air guide cylinder type vertical axis wind wheels through a second-stage chain transmission mechanism. When the first-stage air guide cylinder type vertical axis wind wheel, the second-stage air guide cylinder type vertical axis wind wheel, and the third-stage air guide cylinder type vertical axis wind wheel rotate, they can drive the generator to rotate for power generation. The generator is connected to the control system and the storage battery. The control system is used to adjust the output load of the generator according to the wind force, and then adjust the rotational speed of the air guide cylinder type vertical axis wind wheel. When the wind force increases, the output load of the generator is increased, so that the rotational speed of the air guide cylinder type vertical axis wind wheel is lower than the preset highest threshold. When the wind force decreases, the output load of the generator is decreased, so that the rotational speed of the air guide cylinder type vertical axis wind wheel is higher than the preset lowest threshold. Thus, the air guide cylinder type vertical axis wind wheel is in a fixed rotational speed range in any wind speed environment;

[0006] The air guide grille cylinder of the multi-stage air guide cylinder type vertical axis wind turbine - also has a photovoltaic panel installed at the upper end, and the photovoltaic panel is connected to a storage battery through a control system.

[0007] Furthermore, the air guide cylinder type vertical axis wind turbine includes an air guide grille cylinder - and a vertical axis wind turbine -, and the first-stage air guide cylinder type vertical axis wind turbine, the second-stage air guide cylinder type vertical axis wind turbine, and the third-stage air guide cylinder type vertical axis wind turbine are all installed on a support platform.

[0008] Furthermore, an inverter is provided between the output end of the generator and an external load.

[0009] After the present invention adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0010] 1. The multi-stage air guide cylinder type vertical axis wind turbines are connected in an array echelon and drive a generator to generate electricity through a chain drive mechanism. The variable current controller changes the output load according to the wind force, so that the air guide cylinder type vertical axis wind turbine always rotates slowly with the wind. This can not only reduce noise and mechanical wear, but also improve the power generation efficiency and reduce the equipment cost;

[0011] 2. The air guide cylinder type vertical axis wind turbine is used as the support column network of the photovoltaic panel ceiling. The vertically rotating wind turbine is installed in the air guide grille cylinder and rotates slowly, enabling the realization of dual wind-solar energy power generation in densely populated areas with large electricity consumption. The application scenarios can be diversified, saving land and reducing the construction cost;

[0012] 3. The multi-stage air guide cylinder type vertical axis wind turbines of the present invention are connected to each other, and the kinetic energy can be normally transmitted through the chain drive method, which is more reliable. And there are various combination methods, which can change according to the changes of the construction site, and the requirements for the site are lower.

[0020] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0021] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] As Figure 1 and Figure 2 shown, the air duct type vertical axis wind turbine 1 is composed of an air duct grille cylinder 1-1 and a vertical axis wind turbine 1-2; the air duct type vertical axis wind turbine 1 is installed on the support platform 2; the air duct type vertical axis wind turbines 1 are connected in series by a chain drive mechanism 3 in a ladder-like manner; multiple groups of air duct type vertical axis wind turbines 1 connected in series are respectively connected to the generator 4 and the control system 5 by a chain drive mechanism 3; the photovoltaic panel 6 is installed on the top of the air duct type vertical axis wind turbine 1, and the air duct grille cylinder 1-1 serves both as the air guide plate of the vertical axis wind turbine and as the support column network of the photovoltaic panel 6;

[0023] When there is wind, the incoming wind adjusts the wind direction through the air duct grille cylinder 1-1 and pushes the vertical axis wind turbine 1-2 to rotate in one direction. Multiple groups of vertical axis wind turbines 1-2 are connected in an array through the chain drive mechanism 3 and jointly drive the generator 4 to generate electricity; the converter in the control system 5 adjusts the output load according to the wind force, so that the vertical axis wind turbine 1-2 rotates slowly with the wind, reducing noise and mechanical wear and improving the power generation efficiency;

[0024] When there is sunlight, the solar energy is converted into electrical energy through the photovoltaic panel 6; the wind power generation and solar power generation share a set of energy storage and transformation system. Due to the complementarity of wind energy and solar energy in day and night and seasons, the configuration quantity of the storage battery can be greatly reduced.

[0025] The multi-stage air guide cylinder type vertical axis wind wheels of the present invention are connected to each other, and the kinetic energy can be normally transmitted through the chain drive, which is more reliable. Moreover, there are various combination methods, which can be changed according to the changes of the construction site, and the requirements for the site are lower. For example, Figure 3 In the shown Embodiment 1, there are three stages of air guide cylinder type vertical axis wind wheels connected in series. As Figure 4 shown in Embodiment 2, there are two stages of air guide cylinder type vertical axis wind wheels, and the two two-stage air guide cylinder type vertical axis wind wheels form a cross shape. Embodiment 1 and Embodiment 2 are applicable to different site environments and can be selected and set according to needs during use.

[0026] The above is an example of the best implementation mode of the present invention. The parts not described in detail are all common general knowledge of those of ordinary skill in the art. The protection scope of the present invention is subject to the content of the claims, and any equivalent transformation based on the technical inspiration of the present invention is also within the protection scope of the present invention.
