Self-steering solar driven mechanical water pump device based on thermoacoustic effect

Abstract

The invention discloses a self-steering solar driven mechanical water pump device based on a thermoacoustic effect. The self-steering solar driven mechanical water pump device comprises a self-steering solar concentration device, a thermoacoustic engine, a pointed-type special water pump and a power transmission system, wherein the self-steering type solar concentration device comprises a Fresnel lens, a spring traction device, a lens bracket and a double-layer vacuum concentration tube. The thermoacoustic engine can be a Stirling engine, a travelling wave thermoacoustic engine and a standing wave thermoacoustic engine and is generally composed of a hot cavity, a heat radiator, a cold cavity and a phase modulation mechanism. The pointed-type special water pump comprises four gears, a housing, a bracket and a belt pulley. The power transmission system comprises a belt pulley of an engine module, a belt pulley driving a water pump module and a belt for realizing driving between the belt pulleys. According to the self-steering solar driven mechanical water pump device, solar light and heat are utilized, a power generating loop is canceled, heat energy is directly converted into mechanical energy for driving the water pump to work, and therefore higher mechanical working efficiency and more thorough clean utilization of solar energy are achieved.

Description

technical field [0001] The invention relates to a mechanical device utilizing solar energy, in particular to a self-steering solar-driven mechanical water pump device based on thermoacoustic effect. Background technique [0002] Since entering the era of modern industrialization, the lack of energy supply has become a bottleneck for the further development of society. People are eagerly seeking safe, non-polluting, and abundant alternative energy sources, and solar energy is undoubtedly the most ideal energy source. At present, the application of solar energy is mainly divided into two types: photovoltaic and heat collection. The former converts light energy into electrical energy; the latter directly uses solar thermal energy. On the other hand, water pumps are indispensable fluid mechanical equipment for industry, agriculture and daily life, and are widely used. [0003] Usually water pumps are driven by electricity. If solar photoelectric conversion is used to obtain el...
