Ratio, that is, light bulb ratio of D 0 and runner diameter D 1 is 0.58~0.65.Most of tubular turbine is all this
Structure has fixed guide vane to obtain circular rector before runner, and there are one the same runners of outer image propeller for tail portion.Divide from structure
Analysis, the diameter of runner envelope to draft tube is small, and the water pipe diameter of light bulb section is big, if the blade of runner is arranged on light bulb section, turns
The outer diameter bigger of wheel, same flow are acted on major diameter impeller, the turning moment bigger of output.
Invention content
In order to improve tubular turbine series, the present invention tries hard to provide a kind of tubular turbine with rotating cylinder, turn
The outer image rotating cylinder of wheel is the same, can obtain the turning moment of bigger.
The technical solution adopted by the present invention to solve the technical problems is：Tubular turbine with rotating cylinder has runner, water
There is bulb in pipe, bulb is exactly master section, and a main shaft is stretched out in tail portion, and other positions are sealings；The leaf of runner
Piece is arranged on behind master section, and the blade of runner is arranged in the annulus area between master section and water pipe, this
A annulus area is the minimum overflow section in length of pipe, the outer image cylinder of runner, also referred to as rotating cylinder, the outer diameter of rotating cylinder with
The outer diameter of bulb is equal, has helical blade above the outer diameter of rotating cylinder；The main shaft other end is connected with bearing block, the outside of bearing block
It is connect with rear support, the outside of bulb is connect with front support, and rotating cylinder is connect with main shaft.Helical blade is distributed on the circle of rotating cylinder
Week, the quantity of helical blade are more than 1, and helical blade circumference uniform distribution centered on the axis of rotating cylinder, helical blade is around rotating cylinder
Axis spiral.
Tubular turbine with rotating cylinder, method of work be, it is characterized in that：Water in water pipe passes through by master section
During rotating cylinder, helical blade is impacted, helical blade pushes rotating cylinder to rotate and drive main shaft, and the main shaft of rotation finally drives generator again
Rotation；Annulus area between master section and water inlet pipe is minimum, and annulus area is set smaller than the smallest cross-sectional face of water pipe
Product, same water pipe flow, this position flow is most fast, and the helical blade of rotating cylinder is arranged in this position, can obtain compared with flood
Motive force, on the other hand, the outer diameter of this position helical blade is larger, when the thrust of water is when on helical blade, obtains
The torque obtained is also larger.
The invention has the advantages that the tubular turbine with rotating cylinder, runner outer shape is as rotating cylinder, spiral above
Blade is long, and the distance of water acting, the blade of runner is arranged on behind master section, and the blade of runner is arranged on generator
In annulus area between part and water pipe, the annulus area between master section and water inlet pipe is minimum, this position flow
Fastest, the largest outside diameter of this position helical blade, when the thrust of water is when on helical blade, the torque of acquisition is most
Greatly.It is more suitable for the power generation of low water head or reduces the bodily form of the hydraulic turbine.
