Abstract

The invention provides a continuous power generation device in rotating process of a piezoelectric mine hoist. The continuous power generation device comprises an upper base and a lower base which are symmetrically buckled and fixed on a rotating shaft; energy acquisition modules, rectifying modules and energy storage modules are symmetrically arranged on the upper base and the lower base at intervals in sequence; protective hoods fixed on the bases are hooded at the outer parts of the energy acquisition modules, the rectifying modules and the energy storage modules; each energy acquisition module comprises a box-shaped piezo-electricity sleeve; a mass rod is arranged in the piezo-electricity sleeve; four piezoelectric plates clung to the cylindrical surface of the mass rod are symmetrically arranged on the periphery of the mass rod; the four piezoelectric plates are mounted on the walls of a square groove formed in the hollow inner circle surface of the piezo-electricity sleeve in a symmetrical fit. Through the adoption of the energy acquisition modules, the mechanical energy such as gravitational potential energy and vibrational energy in the rotating process of the rotating shaft of the hoist are continuously converted into electrical energy, then, the electrical energy is stored by the rectifying modules and the energy storage modules, the power supply is provided for a rotation monitoring system, no electromagnetic field interference is generated in wireless transmission, the use is convenient and the maintenance cost is low.

Description

technical field [0001] The invention relates to a continuous power generation device during the rotation process of a piezoelectric mine hoist, which belongs to the technical field of energy and electronics. It is especially suitable for converting mechanical energy such as vibration energy into electrical energy to provide power for rotation monitoring systems. Background technique [0002] At present, the structure of rotating equipment is becoming more and more complex, and its functions are also rich and diverse, and the requirements for its safe operation are getting higher and higher. Therefore, real-time health monitoring of key rotating parts of rotating equipment has received extensive attention and research. When constructing a monitoring system for rotating parts, the traditional wired data transmission form shows great limitations. Therefore, wireless transmission technology has been widely used. However, the monitoring system based on wireless transmission has ...
