Abstract
The present invention discloses a through flow type unit water guide mechanism. It includes the following several portions: guide blade, guide blade lower shaft, guide blade arm, sleeve, connecting plate, shearing pin, control ring and internal and external water distribution rings. Said invention also provides the concrete structure of the above-mentioned every portion, and the working principle of said through flow type unit water guide mechanism.
Description
Technical field
The present invention relates to a kind of through-flow type machine set water guiding mechanism.
Background technique
Along with the exploitation of low head hydropower station, tubular turbine obtains application more and more widely.Present most of tubular turbine water guide structure exists that hydraulic loss is big, not good, the not high shortcoming of efficient of water sealing effect more, influences applying of tubular turbine.
Summary of the invention
The objective of the invention is to, a kind of novel through-flow type machine set water guiding mechanism is provided, when both having guaranteed that water guide structure was opened, stator rotates flexibly, and inflow-rate of water turbine is big, and the water guide performance is good, and when guaranteeing that again water guide structure is closed, the Surface of action water shutoff performance at stator two ends is good.
The technical solution adopted in the present invention is: a kind of through-flow type machine set water guiding mechanism, comprise stator, sleeve, stator lower shaft, guide vane lever, connecting plate, break pin, control ring, interior admission water ring and outer gate barrel, stator is tapered, the narrow end of the taper of stator connects the stator lower shaft, and the wide end of the taper of stator is connected with control ring through connecting plate, break pin successively by guide vane lever.
It is wing that the stator longitudinal cross-section is streamline, stator central axis and unit rotary middle spindle are 60 ° or 65 ° of angles, Sealing Surface and unit rotary middle spindle that all stators constitute are space distribution, the spatial warping structure of oblique like this water guide structure and stator can effectively make current be easy to by and form the required circular rector of runner.
The stator two ends are spheric structure, connect interior admission water ring at the narrow end of stator taper, be with sleeve on the guide vane lever, between wide end of stator taper and sleeve, outer gate barrel is set, interior admission water ring and outer gate barrel cooperate with narrow end of stator taper and the wide end sphere of taper respectively, guarantee stator water shutoff effectively.
But control ring connection closed weight when speed regulator loses oil pressure, except that the Hydraulic Moment of stator itself, can rely on by what weight formed and cut out the reliable guide vane closing of moment, prevents that unit from flying ease,
Invention advantage of the present invention is, adopts stator central axis and unit rotary middle spindle to be the oblique water guide structure of 60 ° or 65 ° angles, and the spatial warping structure of cone guide vane, current be easy to by, improved inflow-rate of water turbine and energy conversion efficiency greatly.The stator two ends are spheric structure, and after interior outer gate barrel sphere cooperated, good with connected element engagement property, water sealing effect was good.
