Description
Technical Field
The invention belongs to the field of wave energy power generation, and particularly relates to an asymmetric air turbine suitable for an Asian sea oscillating water column type wave energy power generation device.
Background
Wave energy refers to the kinetic and potential energy possessed by ocean surface waves, and is proportional to the square of wave height, the motion cycle of the waves, and the width of the wave-facing surface. Although wave energy is one of the most unstable energy sources in the ocean, its reserves are quite considerable worldwide, with theoretical estimates of about 17 TW.h each year. According to the different working principles of the device for absorbing wave energy, the wave energy power generation device can be divided into three types of oscillating water column type, wave surmounting type and oscillating body type. In contrast, the oscillating water column (Oscillating Water Column, abbreviated as OWC) wave energy generating device has a simple structure, can be combined with a breakwater device to reduce the construction cost, and meanwhile, has higher reliability and is more convenient to maintain because the energy conversion device is not contacted with seawater. Large OWC installations since 2010 were a breakwater installation in the north museku harbor of spain, a U-breakwater type REWEC3 installation in the Civitavecchia harbor of italy, a rear elbow floating CORES installation in the Galway bay of irish, and a fixed Yongsoo installation in the island of korea.
The air turbine is an important part for energy secondary conversion in the OWC device, can realize unidirectional rotation in the reciprocating airflow, and converts low-pressure air kinetic energy generated by the air chamber into shaft work of the rotating shaft. The application of the air turbine in the OWC device has a certain specificity: the working medium is reciprocating air flow, and has unsteadiness and compressibility; its operating characteristics allow the possibility of a negative power output of the turbine during operation. There are two common self-rectifying air turbines: weiersi turbine and impulse turbine. The traditional Weiersi turbine has the advantages of simple structure and high peak efficiency, is suitable for European sea areas with good wave conditions, has extremely high efficiency in a small range of flow coefficient before stall, but once stall occurs, the huge reduction of torque can cause the turbine performance to be instantaneously deteriorated, and the defects of the Weiersi turbine also comprise the aspects of poor self-starting performance, narrow working range, high working noise and the like. Although the peak efficiency of the traditional impact turbine is lower than that of the Weiersi type turbine, the traditional impact turbine has good starting performance, no stall phenomenon and slow efficiency reduction in a large flow coefficient area, and is particularly suitable for Asian sea areas with poor wave conditions, but most of the traditional impact turbine is symmetrical, namely the profile of the moving blades and the positions of the guide vanes are symmetrical to the center line of the moving blades along the rotating direction, and engineering shows that the airflow amplitude of the OWC device passing through the impact turbine in the air chamber expiration stage of the Asian sea area is larger than that in the inspiration stage, so that a large amount of power is lost in the expiration stage.

Further, the turbine shaft is connected with a power input shaft of an air turbine external generator.
Further, the air turbine is fixedly connected with the inner wall of the guide cover through the upper ring of guide vanes and the lower ring of guide vanes.
The beneficial effects of the invention are as follows:
the vertical section of the moving blade of the asymmetric air turbine suitable for Asian sea area is crescent, the protruding radian of one side of the crescent is larger than that of the other side of the crescent, and the side with the larger radian is set to be the flow facing side of the exhalation stage, so that the flow facing area of the pressure surface of the moving blade at the high incident flow speed of the exhalation stage can be increased, the flow velocity separation phenomenon of air flow on the suction surface of the moving blade is delayed, the power loss generated when the air flow driven blade enters the downstream guide blade is reduced, the power utilization efficiency of the air turbine in the exhalation stage is improved, and the cycle average efficiency of the air turbine in the actual sea condition is further improved.
In the air chamber expiration stage with larger air flow peak value, compared with a symmetrical structure, the torque coefficient of the asymmetric air turbine disclosed by the invention is greatly improved, and the input coefficient is obviously reduced. Therefore, the working efficiency of the asymmetric air turbine is greatly improved in the expiration stage. Asymmetric air turbines are less sensitive to the asymmetry of the incident airflow than are symmetric air turbines. The more asymmetric the flow velocity of the air flows in the air chamber expiration and inspiration phases, the more the cycle average efficiency of the symmetrical air turbine is reduced; the asymmetric air turbine has good adaptability to the asymmetry of the air flow, and the cycle average efficiency is not affected by the cycle asymmetry of the air flow.
Compared with the Wils type turbine commonly used in European sea areas, the asymmetric air turbine disclosed by the invention has good self-starting characteristic, lower working rotation speed, wider flow coefficient range and lower working noise, and is suitable for being used in the Asian sea areas.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Alternatively, in this embodiment, the hub head is hemispherical or semi-elliptical in shape. As shown in fig. 6, a concentric disk 9 is provided on one side of the rotor blade wheel, and is fixedly connected to the hub by bolts 10, and the turbine shaft passing through the concentric disk is connected to the concentric disk by bearings 7. Four bolt holes 13 are uniformly formed along the circumference of the concentric disc, and bolts passing through the bolt holes fixedly connect the concentric disc with the hub. The concentric discs can play a certain supporting role on the turbine shaft, and further ensure the coaxiality of rotation.
As shown in FIG. 7, the suction surface of the vertical section of the moving blade is formed by a radius R 2 、R 4 R is R 5 The pressure surface is a surface formed by circular arcs with radius R 3 Is provided with a circular arc surface, a suction surface and a pressure surface, and the radius of the circular arc surface is R 1 Is connected with the circular arc of the drawing frame, and the other side is formed by two drawn straight line sections with the radius R 6 Is connected with the circular arc of the frame. Radius R 1 ：R 6 =3: 1. half-partDiameter R 3 、R 2 、R 5 The lengths are the same and R is 4 Twice as many as (x). Device angle θ of straight line segment connected to pressure surface 1 Device angle θ greater than the straight line segment connected to the suction side 2 。
In the use process, the turbine shaft of the air turbine disclosed in embodiment 1 needs to be connected with the power input shaft of the generator outside the air turbine, and the moving blade wheel rotates under the action of air flow to drive the turbine shaft to rotate, so that the generator is driven to generate electricity.
The air turbine is fixedly connected with the inner wall of the guide cover through the upper ring guide vane and the lower ring guide vane, and as the leaf span of the guide vane is larger than that of the moving vane, a certain gap exists between the tail end of the moving vane and the guide cover, so that the moving vane wheel can freely rotate in the guide cover.
One end of a guide cover with the asymmetric air turbine disclosed in the embodiment 1 is communicated with an air chamber outlet of the oscillating water column type wave energy power generation device, and the other end of the guide cover is communicated with the atmosphere. During a cycle of the wave, the process of exhausting the air flow from the chamber outlet through the air turbine is referred to as the exhalation phase, and the phase of exhausting the air flow from the atmosphere through the air turbine into the chamber outlet is referred to as the inhalation phase. Fig. 8 is a graph of the airflow rate time course generated by the chamber of the OWC device in the sea area of asia, showing that the airflow rate is asymmetric in one period, and the airflow rate generated in the expiration period is about 1.5 times of the inspiration period. Therefore, the side of the air turbine moving blade with the large radian is arranged opposite to the outlet of the air chamber so as to improve the power utilization efficiency in the expiration stage, and the side with the small radian is arranged opposite to the atmosphere. The guide vane that is the leading flow, whether in the expiration or inspiration phase, is called the upstream guide vane, and the guide vane that is the trailing flow is called the downstream guide vane.

The tail part of the moving blade is streamline, thus the moving blade consists ofThe accelerated airflow on the upstream side of the suction surface does not have a flow velocity separation phenomenon at the tail part of the moving blade, so that the power loss of the airflow is reduced to a certain extent. On the other hand, the pressure difference between the pressure surface and the suction surface of the rotor blade generates a moment that urges the rotor blade wheel to rotate at a rotational speed ω in the direction of the arrow in fig. 7.
During the inspiration phase, the flow is at a flow rate V I After entering the moving blades, the moment generated by the pressure difference between the pressure surface and the suction surface of the moving blades still rotates the moving blade wheels along the arrow direction in fig. 7, so the asymmetric air turbine disclosed in embodiment 1 can keep the consistency of the rotating direction of the moving blade wheels in the reciprocating airflow generated by the OWC air chamber, continuously convert the low-pressure kinetic energy of the reciprocating airflow into the axial work of the turbine shaft, and further drive the generator to continuously generate electricity.
