Description

Technical Field

[0001] The utility model relates to the technical field of renewable energy, and in particular to a wind, solar and water complementary renewable energy integrated equipment. Background Art

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the development and utilization of renewable energy has become an important issue in today's society. The large-scale consumption of traditional energy such as coal, oil and other fossil fuels not only leads to resource depletion, but also causes serious environmental pollution and global climate change. Therefore, exploring efficient, clean and sustainable energy solutions has become a global consensus.

[0003] Solar energy, wind energy and hydropower are three widely existing renewable energy sources in nature, each with its own unique advantages. However, a single renewable energy system is often limited by natural conditions. For example, solar energy is affected by weather and day and night changes, wind energy has a lower power generation efficiency when there is no wind or the wind speed is too low, and hydropower depends on the stability and flow of the water source. In order to overcome these limitations and achieve the continuity and stability of energy supply, a wind, solar and hydropower complementary renewable energy system came into being. This system can effectively complement each other's shortcomings by integrating solar energy, wind energy and hydropower generation devices, and improve the overall energy utilization rate and power supply reliability. However, this type of power generation device does have some disadvantages. First, the lower electric cabinet is exposed to the sun for a long time, which causes the temperature of the electric cabinet to rise. The electrical components and batteries in the electric cabinet will accelerate aging due to high temperature, reducing the service life and efficiency; second, the solar energy, wind energy and hydropower generation devices are often installed and arranged separately, occupying a large space, which is not convenient for transportation and installation.

Thus, more wind energy can be collected. The main wind generator 411 and the sub-wind generator 412 can be installed by threaded fasteners or other installation methods.

[0054] The energy of the battery 2 is the electric energy generated by converting solar energy into photoelectric energy by the first photovoltaic unit 32 and the second photovoltaic unit 33 , the electric energy generated by converting wind energy by the first wind power generation device 41 and the second wind power generation device 42 , and the electric energy generated by the hydroelectric generator 54 .

[0056] The energy of the air tank 83 comes from wind resources. The air compressor 82 converts wind energy into mechanical energy, and then compresses air and stores it in the air tank 83.

[0057] The above-mentioned storage battery 2 is used to store the electricity generated by the wind, solar and hydroelectric power generation system, and can release the stored electric energy when the sunshine is insufficient, the wind is weakened or the power consumption is at a peak, so as to ensure the stability of power supply. The water collected by the water collection tank 51 flows into the water reservoir 52 through the water inlet pipe 53, and drives the hydroelectric generator 54 to generate hydroelectric power. In addition, the water separated from the air compressor 82 also flows back to the water reservoir 52, forming a water recycling. During the low load period of the power grid or when the first photovoltaic unit 32 needs to be cleaned and cooled, the control unit controls the electric valve 84 to open and release the compressed air in the air storage tank 83.

When the first photovoltaic unit 32 and the second photovoltaic unit 33 receive sunlight and convert it into electrical energy, and the first wind power generation device 41 converts wind energy into insufficient electrical energy, the control unit controls the electric valve 84 to open and release the compressed air in the air tank 83 to blow toward the second wind power generation device 41. The wind power generation device 42 generates electricity and stores it in the battery 2; when the sensor detects that the temperature of the first photovoltaic unit 32 reaches a preset value or the dust reaches a preset value, the control unit controls the electric valve 84 to open so as to blow air to the first photovoltaic unit 32 to cool or clean the first photovoltaic unit 32. At the same time, the second wind power generation device 42 can also collect the wind energy blown out from the first airway port 811 to generate electricity and store it in the battery 2. The water used for cleaning is recovered into the water reservoir 52 through the water collection tank 51. When the water is recovered, it can generate electricity through the hydroelectric generator 54, thereby realizing energy recycling.
