Abstract

The invention relates to a piezoelectric type omni-directional vibrating energy recovery device, belonging to the technical field of new energy and power generation. A frame is mounted on a base by bolts, wherein the frame is a polyhedron provided with piezoelectric vibrators at each side; a piezoelectric vibrator is mounted on the top of the frame; all the piezoelectric vibrators are formed by adhering of metal base plates and piezoelectric wafers and provided with circular holes at the centers; the circular holes are connected with clamping jaws at the ends of bayonet locks in a clamped manner; the piezoelectric vibrator mounted at the side of the frame is connected to the side of an inertia block by the bayonet lock and peripheral springs; the top surface of the inertia block is connected with the piezoelectric vibrator mounted on the top of the frame by the spring at the top and the bayonet lock; and the bottom surface of the inertia block is connected with the base by the spring at the bottom. The piezoelectric type omni-directional vibrating energy recovery device provided by the invention has the advantages that the piezoelectric vibrator is excited by a method of pulling the inertia block by the spring, so that the low-frequency vibrating energy in any directions is recovered; and the reliability and the energy efficiency are high.

Description

technical field [0001] The invention belongs to the technical field of new energy and power generation, and in particular relates to a piezoelectric power generation device suitable for low-frequency and omni-directional vibration energy recovery. Background technique [0002] Micro power generation devices that use piezoelectric ceramic materials to recover environmental vibration energy have become a research hotspot for many years at home and abroad. The successful development and utilization of piezoelectric vibration energy recovery devices can not only solve the power supply problems of portable micro-power electronic products and remote implanted sensor monitoring systems, but also help reduce the waste of resources caused by a large number of waste batteries polluting the environment and producing batteries question. According to the characteristics of environmental vibration and different application purposes, many types of piezoelectric energy recovery devices...
