A suspension hammer self-excited wheel generator

Abstract

The invention relates to a suspending hammer self-excitation wheel type generator, and belongs to the technical field of new energy and electricity generation. A left end cover and a right end cover are mounted at two ends of a shell body through screws, and the bottom of the left end cover and the bottom of the right end cover are respectively provided with a limiting ring and a bearing in an inlaid mode. Sector piezoelectric vibrators are connected between the end covers and the shell body in a pressing mode, and movable magnets are installed at the free ends of the piezoelectric vibrators. A spindle of an excitation disk is arranged in the inner rings of the bearings. A suspending hammer is welded on the outer edge of a disk body of the excitation disk. The disk body of the excitation disk is provided with a fixed magnet in an inlaid mode. The suspending hammer self-excitation wheel type generator has the advantages that the gravity action of the suspending hammer is used for enabling the excitation disk to maintain static relative to the gyration center of the excitation disk, so that the fixed magnet on the excitation disk and the movable magnets on the piezoelectric vibrators generate relative rotation, the effective excitation of the piezoelectric vibrators and the electricity generation are achieved, outside fixing and supporting are of no need, the generator is an independent component, a leaf structure does not need to be changed in the using process, mounting and maintaining are convenient, and the piezoelectric vibrators are high in reliability and wide in effective velocity zone.

Description

technical field [0001] The invention belongs to the technical field of new energy and power generation, and in particular relates to a pendulum self-excited wheel generator, which is used for power supply of a blade monitoring system of a wind power generator. Background technique [0002] The blade is the key component of the wind turbine to receive wind energy and convert it into kinetic energy, which determines the overall reliability and service life of the generator. Wind turbine blades usually work in a harsh environment, and their structural scale, weight and working load are very large. In addition to being damaged by irresistible natural disasters such as lightning strikes and earthquakes, natural corrosion, wear and fatigue stress, etc. Leaf damage is also inevitable. Production practice shows that one-third of the accidents during the operation of wind turbines are caused by blade damage, so the health monitoring of wind turbine blades is imperative. With the in...
