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.

The present invention relates to a displacement amplifying type blunt-body turbulent-flow energy harvester, and belongs to the field of power generation. A reed is arranged on the inner side of the sidewall of a shell, and a framework is arranged on the end portion of the shell. A positioning strip, a boss and a limiting plate are arranged on the left side of the vertical plate of the framework. The boss is provided with a sink hole, and the limiting plate is provided with transverse pin holes. Upper and lower transverse plates are arranged on the right side of the vertical plate. The upper and lower transverse plates are provided with flow passing holes and vertical pin holes. The two ends of a transverse pin are fixed in the transverse pin holes. The pin hole of a lever is sleeved on the transverse pin. The end portion of the left arm of the lever is provided with a pushing block. The end portion of the right arm of the lever is provided with a magnetic block. A coil is arranged in the counterbore of the boss. Transducers are arranged on the two sides of the boss. Each transducer consists of a substrate and a piezoelectric film, wherein the substrate and the piezoelectric film are stuck together. The substrate is in contact with the limiting plate and the pushing block, while no interaction force exists. Pin holes in the two ends of a blunt body are sleeved onto the vertical pin. The two ends of the vertical pin are respectively fixed in the vertical pin holes of the upper and the lower transverse plates. Two springs are sleeved onto the vertical pin. The two ends of the springs are respectively pressed on the blunt body and the upper transverse plate or the lower transverse plate. The wing plate of the blunt body is provided with a magnetic strip. The opposite magnetic poles of the magnetic strip and the magnetic block are facing each other.
Description
technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to a displacement amplified blunt body disturbance energy harvester for powering a river monitoring system. Background technique [0002] There are thousands of rivers all over the territory of our country. In recent years, due to insufficient treatment of industrial wastewater, soil erosion, and improper use of pesticides and fertilizers, most rivers have been polluted to a certain extent. Nearly 1 / 4 of the rivers or river sections cannot meet basic irrigation due to pollution. need. In addition, because the current flood control facilities for small and medium-sized rivers in many areas are not perfect, or even do not have any flood control facilities, when the flood season comes, it may cause dangers such as embankment failure or flooding, directly threatening the lives and property safety of people along the coast. Therefore, river monitoring has been high...
