Problems solved by technology

However, because the main part of photovoltaic power generation, that is, solar panels, only have a high conversion efficiency for a certain light band, while natural light has shortcomings such as wide light band, poor directionality, and low energy transmission and reception efficiency, the efficiency of traditional photovoltaic power supply is not very good. Meet the power efficiency requirements of flywheel energy storage

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 As shown, the core components of the laser space energy transmission technology mentioned in the present invention are the laser and the laser beam expander in the figure. The system uses solar battery arrays to store electricity as the power supply of the flywheel storage module, which is the focus of realizing the system without power supply.

[0017] The present invention selects a solar panel with better spectral response to light of medium wavelength (400-700nm) as the solar cell array 2, and selects a tunable dye laser that is widely used and can emit corresponding wavebands as the laser.

[0018] It is known that the laser has the advantages of concentrated energy and good directivity, so before the solar cell 2 at the receiving end, according to the distance and position between the laser and the cell array 2, a suitable optical lens co...

Abstract

The invention relates to a mixed power storage system of laser wireless power transmission and flywheel energy storage. The mixed power storage system comprises an energy transmitting terminal and an energy receiving terminal, wherein the energy transmitting terminal comprises an energy conversion device converting regeneration energy into electric energy, a laser drive circuit and a laser. The energy conversion device generates electric energy, the laser drive circuit drives the laser to output laser light, and the laser is a tunable dye laser. A laser beam expanding apparatus is arranged between the energy transmitting terminal and the energy receiving terminal according to the distance between the two, shapes laser light output by the laser, and expands output light spots which can be covered uniformly on a solar battery array (2) on the receiving terminal. The energy receiving terminal comprises a solar battery array (1) and a flywheel energy storage module. The mixed power storage system is highly efficient.

Description

Technical field [0001] The invention relates to a technology for optical wireless transmission of energy and mechanical storage of electric energy. Background technique [0002] Flywheel energy storage refers to the energy storage method that uses the motor to drive the flywheel to rotate at high speed, converts electrical energy into kinetic energy and stores it, and then uses the flywheel to drive the generator to generate electricity when needed. It is favored as a new energy storage method and has a series of international Domestic patents, such as patent 200510027925, patent CN1333144, patent 201220055658, etc., all protect the mechanical structure of some basic flywheel energy storage systems, but like other forms of power storage devices, flywheel energy storage first requires an external power supply to make the internal flywheel high-speed Rotation, which is the traditional charging process. In addition, because the energy density of the flywheel energy storage met...
