The water pump vibration power generation device based on the piezoelectric effect comprises avibration amplitude amplification mechanism, the input end of which is fixedly connected with a water pump; the output end of the vibration amplitude amplification mechanism is in driving connectionwith a frequency reduction device; the driving end of the frequency reduction device rotates at the frequency, which is lower than the vibration frequency of the water pump, so that a piezoelectric device is driven to extrude a piezoelectric component in the piezoelectric device to generate power; the vibration amplitude amplification mechanism can perform vibration amplitude amplification of high-frequency small vibration amplitude of the water pump; the fact that the vibration amplitude of the water pump can be converted and utilized can be ensured, wherein the frequency reduction device ismainly used for preventing the piezoelectric component from being subjected to high-frequency impact; therefore, the whole device has the reliable service life; simultaneously, the kinetic energy of vibration of the water pump is recovered, so that illumination is realized; and building energy conservation is further realized.

Description

technical field [0001] The invention relates to the application field of piezoelectric power generation, in particular to a water pump vibration power generation device based on piezoelectric effect. Background technique [0002] As the global temperature rises year by year, all countries have put forward the slogan of energy saving and emission reduction. Building energy consumption accounts for 1 / 3 of the total energy consumption in society. How to minimize building energy consumption while meeting demand is a hot technical topic at present. The building is equipped with a water supply system, and the water pump room of the water supply system is generally installed on the basement floor. Since natural lighting cannot be used, there is a lighting load all year round. Years of lighting use will accumulate a large amount of electricity consumption. Moreover, the water pump will vibrate when it is working, and a large amount of kinetic energy will be dissipated in the form ...

Years of lighting use will consume a lot of electricity

Moreover, the water pump will vibrate when it is working, and a large amount of kinetic energy will be dissipated in the form of vibration. From the perspective of solving building energy conservation, how to provide a device with good reliability and which can convert the recovered kinetic energy into electrical energy to solve the problem of water pump room lighting needs, realizing building energy saving has become a technical problem that technical personnel in the field need to solve urgently

[0003] In the prior art, there is a way to directly realize the energy recovery of vibration through devices such as piezoelectric sheets to solve the above problems. However, if the piezoelectric device is directly placed under the water pump, due to the high-frequency vibration of the water pump, the piezoelectric device will be subjected to a load within a few seconds. Hundreds of impacts greatly reduce the service life of the piezoelectric device and reduce the reliability of the entire device
