Abstract
The present invention provides a wind-directly-driven oil pumping machine, comprising an electric motor (1) and a control device (14), and further comprising a rotary spindle (2), a blade (3), a lifting roller (4), a roller driving wheel (6), an energy adjustment flywheel (7), a generator (10), a transmission (8) and an energy feedback device (9). The blade (3) is fixedly connected to the rotary spindle (2). The lifting roller (4) is used for raising and lowering a sucker rod. The lifting roller (4) sleeves the rotary spindle (2). Clutches (5) are disposed between the rotary spindle (2) and the lifting roller (4). The clutches (5) are used for separating or joining the rotary spindle (2) and the lifting roller (4). The roller driving wheel (6) and the lifting roller (4) are fixedly connected to form a whole. The wind-directly-driven oil pumping machine is simple in structure, cheap, low in energy consumption, high in efficiency, stable in operation, and low in failure rate, and incurs no pollution to the power grid, thereby utilizing the wind energy efficiently and improving main performance indicators of the oil pumping machine.
