The invention discloses a piezoelectric power generation device based on water flow impact, and belongs to the field of piezoelectric power generation. The piezoelectric power generation device is composed of a flushing plate, a linkage reed, a main extrusion plate, a cymbal-shaped piezoelectric element, a traction shaft, a small extrusion plate, a linkage rod, a magnet block and a spring. The flushing plate is connected with the reed through a double-side hook structure; the reed is connected with the extrusion plate through the spring, and a fine hole is formed in the rear portion of the flushing plate and is used for installing the linkage rod; one end of the linkage rod is connected with the flushing plate, the other end penetrates through the piezoelectric block to reach the rear traction shaft, and the traction shaft and the small extrusion plate jointly act to generate secondary extrusion; the flushing plate is connected with the linkage reed and the linkage rod; the flushing plate is directly flushedby the water flow to generate a certain inward extrusion effect; the flushing plate is connected with the reed through the double-side hook structure; the linkage reed is connected with the extrusion plate through the spring, and a magnetic block is placed between the traction shaft and the extrusion plate; and a piezoelectric vibrator is the cymbal-shaped piezoelectric element.
Description
technical field [0001] The invention relates to a piezoelectric power generation device based on water flow impact, belonging to the field of piezoelectric power generation. Background technique [0002] Hydropower generation is a common and green energy method in today's era. People have been looking for new power generation methods, and there are thousands of rivers scattered throughout my country, with sufficient hydropower resources. Sufficient resources also bring sufficient 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 natural disasters such as flood control and mudslides. Water velocity monitoring technology and many other aspects. Although some monitoring methods proposed at present are relatively mature in technology, they have not been popularized and app...
