Pipeline pressure pulsation energy collecting device with supercharging device

Abstract

The invention discloses a pipeline pressure pulsation energy collecting device with a supercharging device, and belongs to the technical field of hydroelectric generation and low-power-consumption newenergy. The device is composed of a pressurizing pipeline, a main pipeline, a base, a top cover, a plastic film, a piezoelectric stack, a mechanical amplifier, a piezoelectric frame and a sealing rubber ring. The pressurizing pipeline is connected with the main pipeline through threads, the sealing rubber ring is installed between the pressurizing pipeline and the main pipeline, the piezoelectricstack is pasted on the piezoelectric frame and is connected with the mechanical amplifier through pasting, and the mechanical amplifier is fixed above the main pipeline through a stud. When water flow passes through the pressurizing pipeline, the pressure pulsation of the pipeline is increased and transmitted to the plastic film to generate vibration, and the vibration is transmitted to the piezoelectric stack after passing through the mechanical amplifier, so that the piezoelectric stack deforms to generate electric energy. Since pipeline pressure pulsation is increased, the vibration amplitude generated by the pressure pulsation is amplified and the energy collection efficiency is improved, and the device is simple in structure, low in cost and easy to popularize.

Description

technical field [0001] The invention is a water energy capture device based on pipeline water flow pressure pulsation, which can effectively collect the water energy in the pipeline and convert it into electric energy, and belongs to the technical field of hydropower generation and low power consumption new energy. Background technique [0002] With the rapid development of information and electronic technology, a large number of wireless sensor products have come out, but the energy supply problem of wireless sensors is still an urgent problem to be solved. The energy supply method has disadvantages such as short battery life and frequent replacement. In order to overcome the shortcomings of traditional energy supply, it is found that it is a good alternative to obtain and supply energy directly from the environment. There are various forms of harvesting technologies, which are mainly related to their application environment and energy supply methods. Of course, the energy...
