Description

technical field [0001] The invention relates to a power generation device, in particular to a wind-solar combined power generation device. Background technique [0002] Power generation refers to the production process of converting water energy, thermal energy of petrochemical fuels (coal, oil, natural gas), nuclear energy, etc. into electric energy by using power generation power plants to supply the needs of various sectors of the national economy and people's lives. At present, the more common power generation methods include thermal power generation, hydropower generation, nuclear power generation, wind power generation, and solar power generation. [0003] Among them, wind energy and solar energy are widely used as renewable green energy sources. Wind power generation is to convert the kinetic energy of the wind into electrical energy. Wind generators generally include wind rotors, generators, steering gears, towers, etc. The towers need to support the wind rotors, ge...

Problems solved by technology

For example, a Chinese patent with application number 201220034168.0 discloses a wind-solar hybrid power generation device, which includes a vertical support rod, a wind generator at the top of the support rod, a solar panel at the middle of the support rod, and a In the control box, one end of the solar panel is hinged to the support rod, and the other end is respectively hinged to one end of two push-pull rods located below it. The push-pull rods are pushed and pulled through the gear and rack structure driven by the motor, thereby changing the angle of the solar panel Change to achieve solar tracking control. This kind of power generation device that combines wind power and photovoltaics simply limits the rotation angle of solar panels, and cannot achieve dual-axis, omnidirectional, and multi-angle solar tracking. In addition, the wind power bracket needs to be redesigned during installation. However, the existing wind power support cannot be used, which not only greatly increases the cost, but also increases the difficulty of construction; another example is a Chinese patent application with application number 201310125778.0, which discloses a solar panel-based intelligent protection wind-solar hybrid power generation device, including a support frame , solar panel components, installation platform, wind turbine and drive mechanism, the drive mechanism includes a horizontal drive mechanism and a vertical drive mechanism, this power generation device adjusts the angle of the solar panel by monitoring the wind speed and direction, so that it is affected by the wind pressure Minimize and avoid wind damage to the solar panel, but its driving mechanism drives the supporting frame to rotate together, and the driving mechanism is exposed, without protection and lubrication, it cannot achieve long-term tracking of the sun, and its life and strength will be affected to a certain extent. Turning the entire support rod requires a large torque, so the horizontal drive and vertical drive dual shafts cannot be combined together, the structure is not compact, and it cannot carry high-power solar panels

At present, no matter what type of solar panel drive mechanism, it is difficult to meet the two tracking directions to rotate 180°, the tracking light is not sufficient, and there are dead angles; in addition, due to its own weight and the invasion of natural wind, the drive mechanism needs to carry a large load load, resulting in a drive mechanism that is either bulky or weak, with insufficient durability
