Self-generating type streetlamp for generating power by utilizing pressure difference and use method thereof

Abstract

The invention relates to a self-generating type streetlamp for generating power by utilizing the pressure difference and a use method thereof. The self-generating type streetlamp and the use method are characterized in that a vertical column of the streetlamp is internally provided with a plurality of wind-driven generators; the upper part of the vertical column is provided with an arc-surface wind cap; the vertical column is internally provided with a storage battery and an electric connection circuit; the vertical column is made of transparent material; and the northward part of the vertical column is provided with a salt layer. The use method comprises the following steps that airflow flows through the arc-shaped wind cap, the flowing speed is accelerated, the pressure is reduced, and the airflow with high pressure flows from bottom to top to form a gust of strong rising airflow; on the other side, the black salt layer in the vertical column absorbs heat of the sunlight, the heated air flows up to form another gust of strong rising airflow; the two gusts of strong rising airflow pushes the wind-driven generators in the vertical column to rotate and generate power for illumination of the streetlamp. The self-generating type streetlamp and the use method have the beneficial effects that since all the power generating facilities are arranged in the vertical column of the streetlamp, the maintenance probability is lower, so that the use cost is lower. The self-generating type streetlamp utilizes the black salt layer as a solar power generating facility, and has the advantages of low cost and long service life compared with a solar battery panel.

Description

technical field [0001] The invention belongs to lighting equipment, in particular to a street lamp which utilizes natural energy to generate electricity. Background technique [0002] In order to save energy and protect the environment, there have been several street lamps that use solar energy and wind energy to provide electricity. Solar power generation mainly uses solar panels, and wind power generation mainly uses wind generators installed on top of street lamps. The above-mentioned power generating devices are all exposed to the sun and rain, have a short service life, and have a high probability of maintenance, resulting in an increase in use costs. Contents of the invention [0003] The purpose of the present invention is to propose a natural energy-generated street lamp with low maintenance probability for the above-mentioned street lamps generated by natural energy: the power generation device is installed inside the street lamp column that can protect from w...
