A piezoelectric power generation device based on water impact

Abstract

The invention discloses a piezoelectric power generation device based on water flow impact, which belongs to the field of piezoelectric power generation; it consists of a scour plate, a linkage reed, a main extrusion plate, a cymbal-shaped piezoelectric element, a traction shaft, a small extrusion plate, and a linkage rod. , a magnet block, and a spring; the scour plate and the reed are connected by a double-sided hook structure; the reed and the extrusion plate are connected by a spring, and the back of the scour plate is provided with a fine hole for installing a linkage rod; the linkage rod One end is connected to the scouring plate, and the other end passes through the piezoelectric block to reach the traction shaft on the rear side. The traction shaft and the small extrusion plate work together to generate secondary extrusion; the scouring plate will connect the linkage reed and the linkage rod; the scouring plate will directly A certain internal extrusion effect is produced by being washed by the water flow; the flushing plate and the reed are connected by a double-sided hook structure; the linkage reed and the extrusion plate are connected by a spring, and a magnetic block is placed between the pulling shaft and the extrusion plate; The piezoelectric vibrator uses a cymbal-shaped piezoelectric element.

Description

technical field [0001] The invention relates to a piezoelectric power generation device based on the impact of water flow, and belongs to the field of piezoelectric power generation. Background technique [0002] As a common and green energy source in today's era, people are always looking for new ways of generating electricity. There are thousands of rivers in my country, and there are enough water resources. Sufficient resources also bring enough hidden dangers. For these hidden dangers, domestic experts and scholars have successively proposed corresponding monitoring methods and means, including water quality monitoring technology for river water pollution, rainfall, water level and river course for flood control and natural disasters such as debris flow. Water flow velocity monitoring technology and many other aspects. Although some of the monitoring methods proposed at present are relatively mature at the technical level, they have not been widely used. One of the main...

Problems solved by technology

Although some of the monitoring methods proposed at present are relatively mature in technology, they have not been popularized and applied in a large area. One of the main reasons is that the power supply problem of the monitoring system has not been well resolved.
