Description
Technical field
The utility model is related to power station formula waterwheel is hit on waterwheel field more particularly to a kind of bicircular arcs type blade.
Background technology
Currently, exploitation clean reproducible energy is the inexorable trend of human development demand.Water can be green renewable resource,
Its utilization is of great significance.However, with the large-scale development of China's hydroelectric resources, it is preferable to belong to economic indicator
Middle and high head website is fewer and fewer, has become the hot spot of research to the utilization of low water head Midget plant therewith.Water
Vehicle has many advantages, such as that income efficient, at low cost is high in low water head Midget plant, is low water as most ancient water conservancy machinery
The suitable water energy conversion equipment of a kind of economy in head water energy development.How developing one kind using these advantages can answer
Formula waterwheel is hit on low water head Midget plant, efficient, economical to be of great significance.
The mode of exploitation water energy is usually to build power station at present, and water energy, but it are converted using the efficient hydraulic turbine
There is certain requirement to addressing, such as the hydraulic power potentials of some scattered low water heads can not just utilize.If in the streams of low water head
It is upper construction dam improve head, due to build dam there are welding, cost of investment is larger, the completion time of project is longer the shortcomings of,
Cause that water energy transfer efficiency is low, and output power is small, and economy is poor.
The research in relation to the micro-hydro generator using flow dynamic has more document report with application both at home and abroad
Road.In the industrial revolution epoch, water can be a kind of main energy, built thousands of low-head hydraulics using waterwheel and ground
Mill.Since at low water head, the hydraulic turbine has the shortcomings that cost high yield is low as water energy conversion equipment, also have a large amount of today
Hydroelectric resources do not develop, so Baga, Hydrowatt company and waterwheel factory of the U.S. etc. of Germany start production hair again again
Electric waterwheel.Waterwheel is typically considered a kind of water energy conversion equipment of poor efficiency, since the hydraulic turbine is more efficient than waterwheel,
The effect of the water energy conversion equipment of waterwheel has been taken over, and has been widely used in life.But in fact, waterwheel is especially
On to hit formula waterwheel be a kind of effective, low cost water energy conversion equipment, more suitable for use in low water head mini.
In conclusion overcoming the problems, such as that hydraulic turbine efficiency in low water head mini is low, of high cost, exploitation is a kind of high
Effect, waterwheel that income at low cost is high can make full use of water that can close in the place that the standard hydraulic turbine cannot effectively be run
It is suitable to use, it is one of current fluid machinery and hydroelectric project equipment and technology emphasis problem urgently to be resolved hurrily.
Utility model content
The purpose of the utility model is to overcome in the prior art the defects of, provide a pair of circular arc type blade on hit formula water
Vehicle hits formula waterwheel on this and effectively increases waterwheel efficiency.Based on the purpose, the utility model adopts the following technical solution：
Formula waterwheel is hit on a kind of bicircular arcs type blade, including bearing supporting frame, rotation axis, blade and diversion culvert, is turned
Wheel, bearing supporting frame are equipped with rotation axis, and the both ends of rotation axis are connected with blade fixed plate, blade be arranged on blade fixed plate it
Between, blade is spatially circumferentially distributed centered on rotation axis, and the coordinate curve equation of the Curve of wing point of each blade is such as
Under：
(camber line on blade) y=-0.0005x5+0.027x4-0.5183x3+3.4285x2-4.1789x+1039.5
(camber line under blade) y=0.0002x5-0.0088x4+0.123x3-1.6636x2+14.132x+997.7
The arrival end of diversion culvert is higher than its port of export.Blade is arranged to the special construction of bicircular arcs type so that waterwheel energy
Enough there is the impact blade of current smooth-going as much as possible, flowed along blade camber line, reduce hydraulic friction of the current at blade and touch
It hits, reduces the loss of flood peak at vane inlet, improve waterwheel efficiency.After water impact upper blade, by runner, rush again
Lower blade is hit, reaches secondary use, improves waterwheel efficiency.
Further, on the rotating shaft, blade is welded in blade fixed plate for the runner connection.
Further, a diameter of 1~6m of the waterwheel.
Further, for the length of the blade between 1~6m, the quantity of the blade is 15~40.
Further, the arrival end of the diversion culvert is arranged on the top of waterwheel, the port of export peace of the diversion culvert
It is placed at the upper camber line entrance extended line of blade.
Further, the bearing supporting frame is arranged at the both sides of diversion culvert.
The beneficial effects of the utility model are：
(1) compared with traditionally hitting formula waterwheel, the blade of runner reduces water according to the Airfoil Design of special surface radian
Stream significantly increases runner output, improves the efficiency of waterwheel by the shock loss at the entry of blade.
(2) arrangement of runner bucket is using rotation axis as the center of circle, is spatially circumferentially distributed, is fixed on blade and fixes
After can be with water impact upper blade on plate, by runner, lower blade be impacted again, can reach secondary use.
(3) capacity between runner bucket is bigger with respect to fish, and rotating speed is very slow, is migrated for fish in way, is strayed into waterwheel
Fish, can between blade by, even if very long common eel can also safety, effectively solve fish and be difficult to move
It moves, ecological environment damaged and the problem of waterwheel and river biology are difficult to coexist.
