Title:
LIGHTNING STEEL TOWER WITH THUNDER CLOUD SENSOR AND EQUIPPED WITH LIFTING MECHANISM
Document Type and Number:
Japanese Patent JP2004311083
Kind Code:
A
Abstract:

To provide a lightning steel tower with a thunder cloud sensor equipped with a lifting mechanism, capable of automatically setting the height of the tower in multiple steps as thunder cloud approaches.

The thunder cloud detector D is arranged on the ground 2, or other place, or near a lightning object 8. When thunder cloud 9 is generated and grown as to approach to the lightning object 9 or when a lightning strike is likely to occur, the thunder cloud detector D detects it and send a detection signal to lifting mechanism driving means 11 for lifting a lightning steel tower E. The thunder cloud detector D may be an electric field intensity detection type thunder cloud detector. The lifting mechanism driving means built in the lightning steel tower receives the detection signal from the thunder cloud detector D to lift the iron tower by multiple steps by using the lifting means 15 and complete lifting. The thunder cloud 9 discharges toward a lightning rod 3, preventing houses or the lightning object 8 including a windmill for wind power from being hit by a lighting strike. In consideration of the size of a large type wind mill, the maximum extendable height of the lightning steel tower 8 is set around 100 m. When the thunder cloud 9 departs from the lightning object 8, the thunder cloud detector D detects it to send a detection signal to the lifting mechanism driving means. The driving means retracts the lightning steel tower E to restore its original state and complete retraction.
