Abstract

The invention discloses a tunnel wind power generation device. With the adoption of the device, utilization of wind power in a tunnel and electric generation and energy supply functions can be realized. A framework is defined by a left side plate, a right side plate, an upper protecting plate and a lower protecting plate; two wind power receiving covers are fixed at front and back parts of the framework; electric generators on the outer sides of the protecting plates and wind power rotators on the inner sides of the protecting plate penetrate through the protecting plates to be connected; flowdeflectors are fixed between the two wind power rotators; two piezoelectric patches are arranged above each wind power rotator and embedded into the side plates on the two sides respectively; a vibrational thin plate is fixedly connected with the four piezoelectric patches; a storage battery and a rectifier are located in a casing outside the lower protecting plate; electric power generated by the electric generators and the piezoelectric patches is transmitted to the storage battery through the rectifier. The device adopts the tunnel wind power for power generation, has the characteristics of small size, high power generation and the like and is particularly suitable for being used in the railway tunnel.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of power generation mechanical devices, in particular a device that utilizes tunnel wind energy and piezoelectric vibration to generate power. Background technique [0002] With the increasing investment and operation scale of subway projects, more and more attention has been paid to the safety maintenance of subway tunnels. In this context, the tunnel health monitoring system based on wireless sensor network technology (WSN) has been well developed. The energy supply unit of wireless sensor nodes usually uses dry batteries, but due to the long running time and high frequency of the train, the time and personnel entering the tunnel are strictly limited, after the sensor is arranged, the battery is difficult to replace, and it cannot be powered by solar energy like the external structure. If it is exhausted, the nodes will lose their function, which greatly limits the development of...
