Abstract
The utility model relates to a paddle adjustment operation device for a water turbine. The paddle adjustment operation device comprises a transmission rod which is arranged at the tail end of a main shaft; a paddle adjustment piston is in power connection with blades of the water turbine through the transmission rod; the position close to the transmission rod is provided with a disc spring; a locking device which is used for controlling a piston rod is formed by the disc ring, a taper sleeve and a backward lock piston, wherein the taper sleeve is located at the rear end of the disc spring and the backward lock piston is located at the rear end of the taper sleeve. According to the paddle adjustment operation device for the water turbine, a paddle adjustment mechanism driving device is arranged outside a rotating wheel and accordingly the problem that rivers are easy to pollute due to oil leakage is solved; meanwhile the paddle adjustment function of a small rotating wheel unit can be achieved; a pure mechanical taper sleeve self-locking structure is adopted and accordingly the problem of locking and positioning of any position is solved and the gearless and stepless adjustment is achieved.
Description
Technical field
The utility model belongs to water turbine and adjusts paddle mechanism technical field, is specifically related to a kind ofly adopt high oil pressure to realize to adjust oar operation equipment without the blade angle adjustment of shelves, any angular position, auto lock locating function for water turbine.
Background technique
At present domestic water turbine is adjusted paddle mechanism, and it drives oil cylinder (servomotor) is to be arranged in web, and can not adopt high oil pressure.So just there are two deficiencies: the one, hydraulic oil seepage in web and easily ooze out into river from blade pivot, causes environmental pollution; The 2nd, when runner volume hour, in it, hold driving oil cylinder without sufficient space.In addition, current tune paddle mechanism is that stepping has a grade regulative mode.
Model utility content
In order to overcome above-mentioned shortcoming, the utility model provides one will adjust paddle mechanism drive assembly design outside runner, be fixed on main shaft end, realize the location of sizing mixing with pure mechanical tapered sleeve self-locking structure, without oil-filled, adopt high oil pressure to realize and adjust oar operation equipment without the blade angle adjustment of shelves, any angular position, auto lock locating function for water turbine in former web.
The utility model solves the technological scheme that its technical problem adopts: a kind ofly adjust oar operation equipment for water turbine, comprise the drive link that is arranged on main shaft end, the piston of sizing mixing is connected with turbine blade power by drive link, be provided with dish spring near the position of drive link, dish spring be positioned at the tapered sleeve of dish spring rear end and be positioned at the locking device that moves back lock piston formation control piston rod of tapered sleeve rear end.
Described turbine blade is arranged on runner.
Be provided with power transmission pin described moving back between lock piston and tapered sleeve.
The beneficial effects of the utility model are: by adjusting paddle mechanism drive assembly design outside runner, solved the problem that easily causes fluid leakage pollution river; Can realize the tune oar function of little runner unit simultaneously; Adopt pure mechanical tapered sleeve self-locking structure, solved arbitrary position locking and positioning problem, realized without shelves, step-less adjustment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-turbine blade, 2-runner, 3-main shaft, 4-drive link, 5-dish spring, 6-tapered sleeve, 7-move back and lock piston, 8-tune oar piston, 9-piston rod, 10-power transmission pin.
embodiment
Referring to Fig. 1, a kind of for water turbine tune oar operation equipment, comprise the drive link 4 that is arranged on main shaft 3 ends, the piston of sizing mixing is connected with turbine blade 1 power being arranged on runner 2 by drive link 4, be provided with dish spring 5 in the position near drive link 4, dish spring 5 be positioned at the tapered sleeve 6 of dish spring 5 rear ends and be positioned at the locking device that moves back lock piston 7 formation control piston rods 9 of tapered sleeve 6 rear ends, be provided with power transmission pin 10 moving back between lock piston 7 and tapered sleeve 6.
Whole operating device is installed on the end of hydraulic turbine main shaft 3, adjust oar piston 8 reciprocating and drive blade rotary pendulum angle by drive link 4 under pressure oil effect, tapered sleeve 6 produces coupling mechanism force piston rod 9 is locked under the effect of dish spring 5, move back lock piston 7 and under the effect of pressure oil, produce the pretightening force that dish spring 5 is pushed in movement open and releasing dish spring 5 produces on tapered sleeve 6, the coupling mechanism force of tapered sleeve 6 that is be disengaged, tapered sleeve 6 is in releasing orientation, and piston rod 9 can move.
The utility model, by adjusting paddle mechanism drive assembly design outside runner 2, has solved the problem that easily causes fluid leakage pollution river; Can realize the tune oar function of little runner 2 units simultaneously; Adopt pure mechanical tapered sleeve 6 self-locking structures, solved arbitrary position locking and positioning problem, realized without shelves, step-less adjustment.
