Abstract

The vertical shaft wind (water) force engine with automatic feathering of blades in half-period of upwind has a structure that the center of each blade is provided with a blade shaft parallel to a central shaft, the lower end of the blade shaft is fixed on a spoke fixedly connected with the central shaft, the blades can rotate freely around the blade shaft, two small guide shafts parallel to the central shaft are arranged at two ends of the upper part of each blade, and in order to enable the blades capable of rotating freely around the blade shaft to feather automatically in the upwind, a guide disc with a guide groove on a disc capable of rotating freely around the central shaft is arranged on the central shaft and the upper part of each blade. The guide groove is formed by keeping the connecting line of the small guide shafts at the two ends of the upper part of the blade parallel to the wind direction in upwind, and keeping the connecting line of the small guide shafts at the two ends of the blade and the diameter direction of the central shaft of the wind motor to move in a consistent manner in downwind. The central shaft is used as a power output shaft.

Description

Blade autofeather vertical shaft wind (water) force engine during (water) half cycle against the wind

Technical field

The present invention relates to a kind of vertical shaft wind (water) force engine; Promptly when (water) half cycle against the wind blade autofeather vertical shaft wind (water) force engine (because the structure of vertical shaft wind (water) force engine is identical, this paper during only to the contrary wind half cycle autofeather vertical-shaft wind motor structure describe.)。

Background technique

Wind energy has inexhaustiblely as a kind of, and the energy of cleanliness without any pollution receives people's attention day by day, and wind motor is the capital equipment that utilizes wind energy; It can be divided into two types of horizontal axis wind motor and vertical-shaft wind motors, and the wind wheel of horizontal axis wind motor is round a horizontal rotational shaft, and the rotation of wind wheel is vertical with wind direction during work; Because horizontal-shaft wind turbine is placed on the high cat head; And be one can 360 the moving connecting mechanism of degree rotation, self reach tens tons to tens tons, center of gravity is high; Structural instability, and high-order the placement causes installation and maintenance inconvenience.The wind wheel of vertical-shaft wind motor rotates round a vertical shaft, and center of gravity is low, and good stability is easy for installation.At present, vertical-shaft wind motor is because improvement of computer science is researched and developed and got into acceleration, although change to some extent on the force direction with receiving in blade form, the resistance of blade still can't finely solve when the contrary wind half cycle, has influenced the efficient of wind motor.Though and the Da Lie wind motor efficient in the vertical-shaft wind motor is higher, can not self-starting, the speed governing difficulty, bending blade is difficult for making.

Summary of the invention

The objective of the invention is in order to bring into play the advantage of vertical-shaft wind motor; It is high to overcome existing horizontal axis wind motor mounting point, and construction cost is big, and the blade of vertical-shaft wind motor can't reduce at contrary wind half cycle resistance; The Da Lie wind energy conversion system can not self-starting; The speed governing difficulty, bending blade is difficult for the shortcoming of manufacturing, and the vertical-shaft wind motor of a kind of blade low-cost high-efficiency of autofeather when the contrary wind half cycle of design.

Blade autofeather vertical shaft wind (water) force engine (with the hereafter wind motor) during contrary wind of the present invention (water) half cycle; Its structure mainly is the paddle shaft that the center that the former blade that is secured on the wind motor central shaft changes each blade into is arranged a Parallel airflow force engine central shaft; This paddle shaft lower end is fixed on the spoke that is fixedly connected with the wind motor central shaft; The paddle shaft upper end is consistent with the blade upper height; Paddle shaft is equipped with bearing up and down, and blade can freely rotate around this paddle shaft, and the both upper ends thereof of blade has two little axis of guides with the wind motor central axes.In order to make the blade that can freely rotate around paddle shaft autofeather when the contrary wind, the present invention has installed a positioning disk at engine center axle and blade top, and this positioning disk can center on the wind motor central shaft and freely rotate.Guiding groove is arranged on the positioning disk; The little axis of guide of blade upper end and the bearing that can freely rotate on it move along guiding groove; Guiding groove is that the line by the little axis of guide of blade both upper ends thereof keeps parallel with wind direction when the contrary wind half cycle moves; And the track that the little axis of guide is drawn when the line of the little axis of guide at blade two ends is consistent motion with wind motor central shaft diametric(al) when the motion of half cycle with the wind, the guiding groove that the while width is opened by the bearing diameter on the little axis of guide.The direction of positioning disk by windage yaw plane structure is made guiding groove with the wind with the separatrix, center and the wind direction keeping parallelism of contrary wind half cycle.

Because the effect of guiding groove makes the little axis of guide of blade upper end move along guiding groove, thereby when making blade rotate to the wind the half cycle position, blade two ends line is consistent with the radial direction of wind motor central shaft, with the acquisition maximal wind-energy.And when the contrary wind half cycle, blade two ends line is consistent with wind direction, the resistance that blade moves against the wind when reducing against the wind, thus significantly improve the efficient of wind motor.The wind motor central shaft is connected with generator as pto.

The invention has the beneficial effects as follows: because the direction of blade is on-stream parallel with wind direction when the contrary wind half cycle automatically, the resistance when having reduced against the wind is improved the wind engine engine efficiency.The present invention installs on the river that can't build reservoir dam as no dam hydraulic engine, can reduce cost of electricity-generating greatly, reduces the influence to environment.
