Abstract
The invention relates to a disrotation through flow hydraulic turbine wheel with bidirectional generation. It is characterized in that: it comprises two groups of wheels that reversely mounted along the middle axle of hydraulic turbine, which are mounted with S-shape blades in same number and in reverse rotational directions. The invention can realize bidirectional generation, without guide blade. It has simple structure, while the back wheel uses the circular amount at the outlet of front wheel; the water flows out axially. And the positive and passive directions have same efficiency, to fully utilize the tide energy.
Description
Technical field
Can two-way generating belong to the Fluid Machinery and Engineering equipment technical field to revolving the tubular turbine runner, specially refer to the design field of tubular turbine.
Background technique
Tubular turbine is a kind of hydro-electric power generating equipment that is widely used under the present low water head operating mode, also is widely used in tidal power station.Current axially flow into runner bucket, promote the runner acting, and flow out vertically, do not change flow direction basically.Tubular turbine generally is suitable for the head scope below 25 meters, exerts oneself from hundreds of kilowatt to hundreds of thousands kilowatt.
Along with development of industry and agriculture and progress of science and technology, also more and more urgent to the development and use of new energy.At present, in the marine energy exploitation, the tidal power technology is mature on the whole, and main power generating equipment is exactly a tubular turbine.Tubular turbine generally is made up of several parts such as water distributor, runner and runner envelope and draft tubes.Water distributor is installed in before runner and the runner envelope, for the current that enter runner envelope provide certain positive circular rector, so that promote the runner bucket acting; Runner is the main device of transformation of energy, and it is a mechanical energy with the transformation of energy of current, is converted to electric energy at last; Draft tube mainly plays recovered energy, improves the utilization ratio of flow energy.In above-mentioned tubular turbine working procedure, current are one-way flow, and have only a cover runner bucket to rotate along a direction, therefore can only unidirectionally generate electricity.At present, the two-way tubular turbine that adopts S type blade is arranged in tidal power station, this unit has only a cover runner bucket to rotate along a direction, though can realize two-way generating, complex structure, efficient is not high, thereby is not widely used.
Summary of the invention
The objective of the invention is to design a kind of tubular turbine runner that adopts new structure, generator set adopts this runner can realize two-way generating, and simple in structure, and efficient is higher.Can be widely used in tidal power station, further improve the utilization ratio of tidal energy.
The invention is characterized in that contain the runner that two covers are oppositely installed along the water turbine axis, described two runners are equipped with the S type blade of the identical number of blade, the sense of rotation of these two runners is opposite.
Described two cover runners are 45%～95% of mean chord in axial spacing.
The S type number of blade of described two cover runners is 3～6.
The rotating speed ratio of described two cover runners is 1: 1～2: 1.
The present invention compared with prior art has the following advantages and outstanding effect: can two-wayly generate electricity; Need not to assemble stator, simple in structure; Rearmounted runner has utilized the circular rector of preposition outlet of rotary wheel; Current are inflow and outflow vertically, and runner is straight, lose little, efficient height, and efficiently distinguish wide; Forward and reverse efficient is identical under identical operating mode, has utilized tidal energy more fully.
Description of drawings
Fig. 1 is to revolving the structural representation of tubular runner.
Fig. 2 radius is the A-A sectional view at R place, i.e. S type blade profile figure.
Among the figure: the 1-runner envelope; The preposition runner of 2-; The rearmounted runner of 3-; 4-S type runner bucket; The rotating shaft of 5-water turbine; The 6-pivot; The 7-axis.
Embodiment:
Fig. 1 is for provided by the invention to revolving the structural representation of tubular runner.Thisly comprise that to revolving tubular runner two covers adopt the runner of S type blades 4, be respectively preposition runner 2 and rearmounted runner 3, two cover runners all adopt same S type blade 4, constitute one revolving tubular runner.This two covers runner is arranged vertically, the import and export limit of the blade of preposition runner 2 is opposite with the import and export limit installation direction of the blade of rearmounted runner 3, the inlet side that is preposition runner bucket is laid as the outlet limit of rearmounted runner bucket, the outlet limit of preposition runner bucket is laid as the inlet side of rearmounted runner bucket, as shown in Figure 2.Forward and backward sense of rotation of putting runner is opposite, and rotating speed ratio is 1～2.Two cover runners are 45%～95% of blade mean chord in axial spacing.The number of blade of front and rear runner equates, is respectively 3～6.
When working to revolving tubular turbine, current are axial turnover, and water turbine does not need stator.When current were flowed through first runner, the import circular rector was zero, and outlet circulation is a negative value, because the sense of rotation of rearmounted runner is opposite with preposition runner, so the negative circular rector of the outlet of preposition runner is utilized by rearmounted runner, became the positive circular rector of rearmounted impeller inlet.Because two cover runners have all adopted S type blade, thus can realize two-way generating, and forward and reverse water turbine performance is identical under identical operating mode.Employing is simple in structure to the tubular turbine of roulette wheel, and runner is straight, loses for a short time, and efficient is higher relatively, and efficiently distinguishes widely, can utilize tide energy more fully.
