Magnetostriction system for wind tower

Abstract

The invention discloses a magnetostriction system for a wind tower. The magnetostriction system comprises connecting assemblies and a PID intelligent control system, wherein a positioning mechanism comprises an upper positioning frame and a lower positioning frame; the connecting assemblies and expanding and contracting devices are arranged between the upper positioning frame and the lower positioning frame; each expanding and contracting device comprises a magnetostriction mechanism, an ejecting mechanism and an embedding mechanism; each ejecting mechanism comprises a first fixing hood and anextension bar; each magnetostriction mechanism comprises a first sleeving pipe and a magnetostriction rod; each first sleeving pipe is arranged in the corresponding first fixing hood, and is connected with the upper positioning frame; a coil sleeves the outer end of each first sleeving pipe; each magnetostriction rod is arranged in the corresponding first sleeving pipe, and is connected with theupper positioning frame; each first sleeving pipe is connected with the corresponding extension bar through a corresponding first return spring; each embedding mechanism comprises a second fixing hoodand an embedding rod which are connected to the lower positioning frame; and the lower part of each extension bar can penetrate through the corresponding first fixing hood to be connected with the upper part of the corresponding embedding rod in a fitting manner. The magnetostriction system disclosed by the invention is novel in structure and high in creativity, and the rigidity of a tower cylinder of a wind mill which is fixedly connected with the magnetostriction system is changed.

Description

technical field [0001] The invention relates to the field of mechanics and electronics, in particular to a magnetostrictive system for a wind tower. Background technique [0002] As a clean energy, wind energy has obvious characteristics compared with other types of energy: the utilization and collection of wind energy are not subject to geographical restrictions, and the origin of wind energy resources on the earth comes from the gas flow under the action of solar energy, which can be said to be invaluable It is exhausted and inexhaustible, and has a better future development space, so the development and utilization of efficient and safe wind energy as much as possible can solve the global energy crisis in the future under the premise of environmental protection. At present, wind power generation is the main form of wind energy utilization. The principle is to use air resources to convert the kinetic energy of wind into electrical energy, thereby obtaining electrical energ...
