Solar photovoltaic generating system illumination device applied to building tower crane

Abstract

The invention relates to a solar photovoltaic generating system illumination device applied to a building tower crane, belonging to the technical field of new energy resource application. In the daytime, the sunlight irradiates a flexible amorphous silicon film solar battery arranged on the top of the cab of the building tower crane to generate direct current, and the direct current is input into a controller to be regulated and subsequently is input into a lithium ion battery through a photosensitive automatic control switch to be stored for later use; at night, the direct current output from the lithium ion battery is input into 5-50 LED (Light-Emitting Diode) illumination lamps of 0.06-1 watt on an LED illumination lamp support above a crane jib through a conductor wire, the photosensitive automatic control switch and a controller to make the LED illumination lamps emit light to light up the space around the crane jib, and thus, a driver can see clearly a heavy lifted perpendicular to a steel wire rope when carrying out night work, and staffs standing on the ground see clearly the working position and the working condition of each part of the tower crane when in the night work.

Description

technical field [0001] The invention relates to a lighting device applied to a building tower crane by a solar photovoltaic power generation system, and belongs to the technical field of new energy applications. Background technique [0002] Looking back at 2009, the solar energy industry grew against the trend in the sluggish economy of the United States. The income of the solar energy industry in the United States reached 4 billion US dollars, an increase of 36% over 2008, becoming one of the investment fields with the highest returns. "Building on the success of 2009, we hope that 2010 will be a 'breakout year' for the US solar industry," said Resch, president of the Solar Energy Industries Association of America. [0003] China is already a major producer of solar cells. The monocrystalline silicon solar cells, polycrystalline silicon solar cells, and amorphous silicon thin-film solar cells manufactured in China are of good quality and have been exported to many countrie...

AI Technical Summary

Problems solved by technology

[0005] There are more than 400 tower crane manufacturers in China, and 20,000 tower cranes were sold in 2006. Many horizontal jib tower cranes stand on medium and high-rise construction sites. At night, there is no tower crane on the boom and balance arm. Lighting, people standing on the ground can not clearly see the working position and working condition of each part of the tower crane
