NOVELTY - Solar energy and wind energy driving system comprises wind energy driving unit, solar energy driving unit and control unit, where wind energy driving unit comprises water pump, mechanical differential mechanism, mechanical energy storage mechanism, wind energy mechanism, safety pressure relief device, pipeline and control unit. The rotating speed of the wind-driven water pump is balanced by a mechanical differential mechanism, when the pressure of the fire fighting pipeline is reduced to the required pressure. USE - Solar energy and wind energy driving system for complete set of skid-mounted fire-fighting voltage stabilizing equipment. ADVANTAGE - The solar energy and wind energy driving system rationally and reliably apply renewable energy source, so that the water pump is not affected by commercial power, thus saving energy and reliability of the device. The surface layer of the pressure sensor uses a graphene waterproof scale deposition material, which avoids the problem of the water pressure measuring precision and sensitivity caused by the scale of the surface layer forming plate of the pressure sensor. The material has better flexibility and bending property, better self-cleaning performance, strong non-adhesive property, and high heat conductivity coefficient, and can effectively prevent the generation of scale. DETAILED DESCRIPTION - Solar energy and wind energy driving system comprises wind energy driving unit, solar energy driving unit and control unit, where wind energy driving unit comprises water pump, mechanical differential mechanism, mechanical energy storage mechanism, wind energy mechanism, safety pressure relief device, pipeline and control unit. The rotating speed of the wind-driven water pump is balanced by a mechanical differential mechanism, when the pressure of the fire fighting pipeline is reduced to the required pressure. The mechanical differential mechanism is controlled by a pressure sensor signal to enable the wind energy water pump to obtain driving power and drive the water pump, when the water pump pressurization pipeline reaches the upper limit set by the pipeline, then the mechanical differential mechanism is controlled by a pressure sensor signal to enable the wind energy water pump to be separated from the driving power and stop the water pump, and when the wind energy cannot normally drive the water pump, then the mechanical energy storage mechanism releases energy storage through control unit to drive the wind energy water pump. The solar energy driving unit comprises solar direct-current electric water pump, solar inversion component, storage battery, safety pressure relief device and pipeline. The solar direct-current electric water pump is connected with the storage battery and is connected with the fire fighting pipeline through a pipeline. The solar inversion component comprises solar cell and storage battery. The control unit comprises pressure sensor and mechanical differential mechanism controller computer circuit. The surface layer of the pressure sensor is made of graphene scale-proof deposition materials.
