Abstract
The invention relates to a petroleum drilling underground vibration power generating device. The petroleum drilling underground vibration power generating device is characterized in that a vibrating cavity, a cell box and an instrument box are slotted on the short-connected inner wall connected with a drilling rod; the vibrating cavity comprises a plurality of longitudinal vibrating cavities and transverse vibrating cavities; the inner walls of all vibrating cavities are distributed with piezoelectric ceramic wafers for converting vibrating energy transferred from a knocking hammer into electric energy; the piezoelectric ceramic wafers store the generated electric energy into a cell assembly for being used by an underground instrument; and the knocking hammer stably and enduringly works under the support of a spring piece. The invention has the advantages of directly utilizing underground vibrating energy for generating power without providing the electric energy by the ground, having small device size, and being convenient installation and processing. The invention is suitable for the power generation of vibrating energy in the petroleum drilling project.
