Description

Flow-dividing type submerged hydraulic turbine

The utility model relates to a kind of driving machinery, particularly with the matching used water turbine of generator set, driving machinery.Be fit to plant produced.

Existing " drop type " various water turbine can't utilize no drop but the flow velocity per second of water still greater than the water resource more than a meter, (pure water face work type) water turbine is subjected to physical environment (as wind, surge, timber drift etc.) influence bigger " to drift type ", also be an impediment to the normal navigation of boats and ships, spend the utilization ratio that has reduced canal stream greatly thereby occupy the water channel face width as if use in water channel.

The purpose of this utility model is intended to overcome above-mentioned shortcoming of the prior art, design a kind of movably, multipurpose, can make full use of latent pool flow deviding type flowing water type water turbine multiple water resource, that randomness is big.

The purpose of this utility model is finished like this: adopt upper and lower two buoyancy tanks (go up in the buoyancy tank inlet valve and draining pump are housed) to connect with bolt, constitute " framework " of water wheels unit, make upper and lower buoyancy tank become the bearing base of the left and right son of walking around, two rotors of left and right commentaries on classics are respectively charged in separately the bearing support, and the main frame that has just constituted the water wheels units partly; Two gearwheels are contained on the upper-end surface of the left and right son of walking around respectively and the coaxality that guarantees each gearwheel and rotor less than 0.1mm, mesh by two small gears (wherein right side small gear hold concurrently output shaft) again, just constitute this unit star speed increaser portion and overlap; Flow distribution plate is formed, and is cooperated to blade, triangle water-stop sheet with leading by the quiet plate (shape is immutable) of front, moving plate (can open and shrink) and upper and lower two flow distribution plate guide rails of back; Speed regulating mechanism is by actuating motor, worm gear pair, left-handed thread pair, right-handed thread pair, and left and right connecting rod and articulated joint thereof are formed telescopic driving mechanism.The external controlling computer of said structure unit.When current flow to flow distribution plate to blade through two leaves are leading, make two rotors similar " a lantern adorned with a revolving circle of paper horses " left-hand, dextrad rotation on the left and right blades of walking around of directive respectively again.When the water turbine load changes, cause the variation of its output revolutions, the rotating speed that changed to calculate and compared, again comparative result (signal) is fed to power unit, is the parts that drag---the actuating motor of speed regulating mechanism with requiring revolution through controlling computer.Load lightens as water turbine, cause its output revolutions to be risen, presenting to actuating motor instruction by controlling computer is reduction of speed, impels the driven by servomotor speed regulating mechanism to promote flow distribution plate and makes opening movement along its guide rail, causes the current on left and right two rotor blades of directive to reduce, reach the reduction of speed purpose; Vice versa.Because this machine is assembled with floating box device, inlet valve and draining pump are housed in the last buoyancy tank, therefore can similar " submarine " the same: as to drift in water surface work and (be mainly used in the geological condition complexity, be stone riprap beach or mud etc. as the river bed, anchor is a means of fixation), dive and to moor in water and work and (be mainly used in river bed geological condition complexity and drift is arranged on the river surface, in the large-scale river course as raft etc., anchor is a means of fixation), sinking in the bottom, work (is mainly used in the superior smooth river course of river bed geological condition, and in the water channel, use anchor system or base means of fixation).

When the following example structure that will describe in detail in conjunction with the accompanying drawings, owing to all adopt prior art equipment to combine, thereby also have easy to manufacturely, purposes is wide, adaptability is strong, is convenient to advantage such as transportation and on-the-spot I﹠M in the water route again.

Fig. 1 is that the master of a kind of concrete structure of the utility model looks (add and analyse and observe) figure.
