Electromagnetic and electrostatic combined multi-source shaking power generation device

Abstract

The invention discloses an electromagnetic and electrostatic combined multi-source shaking power generation device, which comprises a sliding block. A first fixing block and a second fixing block arearranged at the two ends of the sliding block respectively, and the first fixing block and the second fixing block are movably connected with the sliding block; a first electrode plate is arranged ateach of two ends of the sliding block; a second electrode plate and a third electrode plate which are overlapped with each other are arranged on each of the first fixing block and the second fixing block; and a load is electrically connected between the third electrode plates. The electromagnetic induction principle and the electrostatic principle are matched with each other, various energy collection sources are provided, and energy collection under different shaking scales is achieved. Electrostatic power generation and electromagnetic power generation are combined, so that the system can achieve a better power generation effect under different shaking excitation amplitudes. Due to the use of the hollow column in spherical hinge connection, shaking energy collection in multiple directions is achieved, and multi-directional power generation is achieved.

Description

technical field [0001] The invention relates to the technical field of vibration power generation, in particular to an electromagnetic and electrostatic combined multi-source shaking power generation device. Background technique [0002] With the development of science and technology and social progress, the advancement of sensing and monitoring technology has had a huge impact on human production and living patterns. However, the power supply problem of these sensing and monitoring devices also limits the application of these devices in some remote or difficult-to-reach environments. The disadvantage of traditional battery solutions is that it needs to be replaced regularly, and there are certain hidden dangers of environmental pollution. Therefore, there is a demand for the development of new energy sources. At present, the development and utilization technologies of water energy, solar energy and wind energy are relatively mature and have been applied in actual productio...
