The utility model provides a wind-solar-energy-storage combined energy supply system which comprises a wind energy conversion module 1, a solar energy conversion module 2, an electric storage module 3, a heat storage water tank 4 and an electric heater 5.
The wind energy conversion module 1 is used for converting wind energy into electric energy, and the main technical principle comprises converting the wind energy into mechanical energy, and realizing the output of the electric energy through the action of the mechanical energy.
In particular, in the present embodiment, the wind energy conversion module 1 comprises a wind turbine. Wherein the wind turbine is fixed in the environment, in particular in an environment position where the wind is highly influenced.
In the use process of the wind turbine, wind energy in nature drives the wind turbine to start so as to drive a power generation module or an additional generator thereof to generate electric energy; the wind turbine, the wind turbine with the power generation module, the wind turbine with auxiliary generator operation, the combined structure of the wind turbine and the generator and the technical principle belong to the prior art, and will not be described in detail in this specification.
The solar energy conversion module 2 is used for converting solar energy into electric energy and generating heat energy, and the main technical principle of the solar energy conversion module comprises the use of photovoltaic effect to complete the conversion from solar energy to electric energy.
Specifically, in the present embodiment, the solar conversion module 2 includes a photovoltaic cell; wherein the photovoltaic cells are arranged in the use environment in the form of additional panels or in a uniform arrangement.
In the practical process of the photovoltaic cell, solar radiation can be directly converted into electric energy; at the same time, the surface of the solar energy conversion module 2 is subjected to a phenomenon of temperature rise, which can generate heat energy that can be recovered.
In actual use, both the wind energy conversion module 1 and the solar energy conversion module 2 are adapted to be electrically connected to the electrical load 100 to achieve power supply to the electrical load 100.
It should be noted that, the electric load 100 may be any type of electric power consuming mechanism, and is not limited herein.

In the embodiment of the utility model, the wind energy conversion module 1 can convert wind energy in nature into electric energy, and the solar energy conversion module 2 can convert solar energy in nature into electric energy and simultaneously generate heat energy.
The electric energy converted from the two energies can directly supply power to the electric load 100, and the heat energy generated by the solar energy conversion module 2 can be transferred into the heat storage water tank 4 through the circulating water pump 41, and the heat energy is supplied to the heat load 200 through the fluid in the heat storage water tank 4.
On the basis of the above, the system is further provided with an electric storage module 3 for storing electric energy converted from wind energy and solar energy, and the electric storage module 3 is electrically connected with the electric load 100, so as to ensure continuous supply of the electric load 100 when consuming electricity.
