A water droplet energy harvesting system

Abstract

The invention discloses a water droplet energy collection system, which comprises a housing, in which a fixed shaft is fixedly arranged, and bearings are sleeved at both ends of the fixed shaft, and the fixed shaft is connected to a rotating cylinder through the bearing shaft, and there are many holes on the outer wall of the rotating cylinder in the circumferential direction. There are three sets of friction plates capable of generating electricity by friction. Each set of friction plates is fixed with a number of electrodes. The electrodes include positive and negative electrodes. Any two adjacent electrodes have opposite polarities. The friction plates are connected to the energy accumulator through wires; A water storage cavity is formed between the fixed shaft and the water storage cavity. Baffles are arranged at both ends of the fixed shaft. The bearings are arranged outside the water storage cavity. Fixed connection, the arc surface of the water baffle matches the inner wall of the drum, and there are several rows of through holes on the drum, and the through holes are located at the junction of the Teflon layer and the drum; the invention can make full use of water droplets and generate electricity , improving the power generation efficiency.

Problems solved by technology

[0002] With the development of society and economy, the consumption of fossil fuels has been rising. In order to ensure the sustainability of energy supply, renewable energy has become the main alternative energy to replace and reduce the consumption of fossil fuels. Biomass energy, hydropower, geothermal, solar energy, wind energy and ocean Energy and other renewable energy power plants provide part of the world's energy needs, and the technology is relatively complete. The abundant precipitation resources and tides in nature can become a clean energy source, but traditional hydropower mainly uses electromagnetic generators, electromagnetic generators It requires sufficient water supply and is bulky and inefficient, so it is not suitable for collecting small-scale energy, and the existing electromagnetic generators have low power generation efficiency and cannot adapt to power generation under any water supply conditions. Currently, water droplets or raindrops can be collected and utilized The technology is still in the relatively initial research stage. The existing collection device uses water droplets to impact the piezoelectric film, uses the piezoelectric effect to generate electricity, and realizes the collection of water droplet energy; but this method has the problem of a large number of water droplets remaining on the material If the situation interferes with the normal power generation, and only one plate is used for continuous power generation, the utilization rate of raindrop mechanical energy is low, and the energy collection efficiency is low. Therefore, a new type of water droplet energy collection system with high efficiency is urgently needed
