Wheel track type vertical axis wind turbine structure and operation method thereof

Abstract

The invention relates to a wheel track type vertical axis wind turbine structure and an operation method thereof. The wheel track type vertical axis wind turbine structure is composed of an annular track, power generation trolleys, a connecting frame, cylinder rotor blades, a driving motor, a flywheel energy storage overrun clutch, a flywheel, a reversing center, a spring energy storage overrun clutch, an electromagnetic clutch, a reversing gear, an energy storage spring, a wheel power generation device and the like. The connecting frame and the power generation trolleys which are uniformly distributed on the annular track form an integral structure of the wind turbine; a motor is in one-way speed change, rotor blades installed on the power generation trolleys are driven by the reversing center in a time-sharing mode to rotate at the preset rotating direction and rotating speed, the blades are induced to generate Magnus effect force capable of pushing the power generation trolleys to continuously run along the annular track in a wind field, and trolley wheels drive the power generation device to generate power; during reversing of the rotor blades, redundant load capacity of the motor drives the flywheel to store energy, and inertia energy of free rotation of the rotor is stored by the spring and released to the spring after reversing of the rotor blades; and the number of start-stop power generation devices can enlarge the wind application range of the wind turbine.

Description

technical field [0001] The invention relates to the field of vertical-axis wind turbines, in particular to a wheel-rail type vertical-axis wind turbine structure based on the Magnus effect and an operating method thereof. Background technique [0002] According to the geometrical relationship between the rotation axis and the ground, wind turbines are divided into two categories: horizontal axis and vertical axis. In wind power generation technology, horizontal axis wind turbines are developing rapidly, occupying most of the domestic and foreign wind power generation markets. However, the rapid development of horizontal axis wind turbine technology has not significantly reduced operating costs, and wind power feed-in tariffs remain high. In order to compete with traditional energy sources, wind turbines have chosen to develop in the direction of large-scale, and reduce the cost of wind power by improving the conversion efficiency of wind energy. But unfortunately, the large...
