Abstract: Disclosed is a control method of an airbag-type intelligent control device for vortex-induced vibration of bridges. The airbag-type intelligent control device for vortex-induced vibration (VIV) of bridges includes a control system, which comprises a monitoring device and a control workstation; the monitoring device is used to detect the wind speed and direction near the bridge and the vibration state of the bridge; the control workstation is connected to the monitoring device. The VIV order of bridges is determined based on the detected wind speed, wind direction, and the vibration state of the bridge. The airbag system is mounted on both sides of the bridge and connected to the control workstation; according to the obtained VIV order, the sectional shape parameters of the airbag system are determined, and the airbag system is regulated to have the appropriate sectional shape.

Abstract: The present invention discloses a pollutant generation system. The pollutant generation system includes a pollution source and a pollutant emitter. The pollutant emitter is connected to the pollution source. The pollution source is composed of two gases including air and methane. The flows of the gases are strictly controlled. Then, the gases enter a magnetic bead glass bottle. Due to the disturbance of magnetic beads to the flowing of the gases, the gases are sufficiently disordered, and the two gases are sufficiently mixed by using a spiral tube to generate a uniform and stable pollution source.

Abstract: A hydropower system for generating electrical energy from water flowing along a bank includes a shaft configured to rotate about a vertical axis, an electrical generator configured to generate electrical energy in response to rotation of the shaft, and a first hydrokinetic device including a plurality of blades attached to the shaft and angularly displaced from each other around the axis. A portion of the first hydrokinetic device is submerged in the water within a cavity formed in the bank, and a portion of the first hydrokinetic device extends outside the cavity and is submerged within the flowing water. The flowing water pushes on the blades located outside the cavity, which drives rotation of the first hydrokinetic device and the shaft about the axis.
