Abstract

Provided is an upwind or upriver half-circulation automatic blade feathering vertical shaft wind power and water power engine. The center of each blade is provided with a blade shaft parallel to the central main shaft of the engine, the lower end of each blade shaft is fixed on a spoke fixedly connected to the central main shaft, each blade can freely rotate around the blade shaft, the two ends of the upper part of each blade are provided with two guiding positioning shafts parallel to the blade shaft, A guide disc provided with a guide groove and capable of freely rotating around the central main shaft is arranged on the central main shaft and at the upper parts of the blade in order to enable the blades capable of freely rotating around the blade shafts to perform automatic feathering while rotating against the wind. the guide groove made from the locus drawn along the top ends of the two guiding positioning shafts takes the effects that the connected line of the guiding positioning shafts at the two ends of the upper part of each blade is parallel to the wind direction when the blades rotate against the wind in a half circulation, and the connected line of the guiding positioning shafts at the two ends of each blade which follows the wind in a half circulation moves in the same direction with the diameter of the central main shaft of the wind power engine. The central main shaft is taken as a power output shaft.

Description

Against the wind or against the current blade autofeather vertical-shaft wind and hydraulic engine during half cycle

Technical field

The utility model relates to a kind of vertical-shaft wind and hydraulic engine, i.e. blade autofeather vertical-shaft wind and hydraulic engine when half cycle against the wind or against the current.(because the structure of this vertical-shaft wind and hydraulic 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 purpose of the utility model 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.

The contrary wind of the utility model or blade autofeather vertical-shaft wind and hydraulic engine (with the hereafter wind motor) during half cycle against the current; Its structure mainly is the paddle shaft that the center that the former blade that is secured on the wind motor central principal axis changes each blade into is arranged a Parallel airflow force engine central principal axis; This paddle shaft lower end is fixed on the spoke that is fixedly connected with the wind motor central principal axis; 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 guide-localization axles parallel with the wind motor central principal axis.In order to make the blade that can freely rotate around paddle shaft autofeather when the contrary wind, the utility model has been installed a positioning disk at engine center main shaft and blade top, and this positioning disk can center on the wind motor central principal axis and freely rotate.Guiding groove is housed on the positioning disk; The guide-localization axle of blade upper end and the bearing that can freely rotate on it move along guiding groove; Guiding groove is when rotating a week by the engine center main shaft; It is parallel with wind direction that the line of the guide-localization axle of a blade both upper ends thereof keeps when the contrary wind half cycle moves; And the line of the guide-localization axle at blade two ends is consistent with wind motor central principal axis diametric(al) and when moving, the track that is drawn along two guide-localization axle tops is made when the motion of half cycle with the wind, and the guiding groove width is pressed the bearing diameter making on the guide-localization axle.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 guide-localization axle 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 principal axis, 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 principal axis is as pto.

The beneficial effect of the utility model is: because the direction of blade is on-stream parallel with wind direction when the contrary wind half cycle automatically, the resistance of blade is largely increased the wind engine engine efficiency when having reduced half cycle against the wind.The utility model also can be used as no dam hydraulic engine, on the river that can't build reservoir dam, installs, and can reduce cost of electricity-generating greatly, reduces the influence to environment.
