Description
Technical field
The utility model relates to a kind of for the device of adjusting water turbine paddle angle.
Background technique
Water turbine is the equipment that a kind of transformation of energy with current becomes mechanical energy, and existing water turbine is installed in it in water power plant usually, and the mechanical energy that is converted with utilization drives generator for electricity generation.Because water turbine is to rely on the energy promotion paddle of current to rotate to realize transformation of energy, and current act on paddle under the potential energy situation identical with kinetic energy, the rotational velocity of paddle depends primarily on the angle between itself and the current, the rotational velocity that is paddle is relevant with its angle, for this reason, water turbine adopts the device of adjusting the paddle angle to improve the output power of water turbine usually.
What provide among Fig. 1 is the outward appearance cross-sectional view of water turbine most preferred embodiment in the prior art.As can be seen from the figure, this kind water turbine 10 comprises main shaft 11 and is arranged on the wheel hub 12 of these main shaft 11 ends, and be arranged on paddle 13 on wheel hub 12 outer surfaces, the cursor 15 of the paddle adjusted 13 angles that servomotor 14 are installed in wheel hub 12 and driven by servomotor 14, and servomotor 14 adopts oil hydraulic pump to drive usually, and this oil hydraulic pump comprises oil pump 16 and energy-storing device 17.Because water turbine is to rely on the energy of current to promote paddle 13 rotations, and the potential energy of current and kinetic energy are relatively large, if will be damaged and oil pump 16 and energy-storing device 17 are subjected to the water impact of macro-energy, damaged for preventing that oil pump 16 from contacting with current with energy-storing device 17, in the prior art, usually oil pump 16 and energy-storing device 17 are installed in the outside on the water turbine, and the far place of dried up stream.Though the oil pump 16 on this kind water turbine and energy-storing device 17 also can drive the servomotor to-and-fro motion and realize paddle 13 angles are arbitrarily adjusted, but because oil pump 16 and energy-storing device 17 are installed in the position away from water turbine, pipeline road 18 need enter in the wheel hub 12 from main shaft 11 ends away from wheel hub 12, with this oil pressure actuated servomotor 14 time, because oil pressure enters the other end from an end of main shaft 11, and main shaft 11 is very long, cause oil oil pressure in the process of transmission to reduce, cause oil pump 16 when fuel feeding, must adopt bigger fuel delivery could drive servomotor 14, the volume of the diameter of its oil feed line 18 and oil pump 16 is also relatively large, so, this kind water turbine not only fabricating cost is relative with user cost high, and because oil pressure is difficult to greatly realize long-time sealing, thereby fragile oil pump 16 causes the oil in it to leak, when the impaired oil pump 16 of maintenance, need stop water turbine work for a long time; Simultaneously big because of oil pump 16 and energy-storing device 17 volumes, it need be installed on the big relatively civil works, improve its installation cost.
Summary of the invention
The purpose of this utility model provides a kind ofly to be utilized the mode that changes drive location to solve to make and the device that is used for adjustment water turbine paddle angle of problem such as cost of production height and life-span be low.
The device that be used for to adjust water turbine paddle angle that the utility model proposes comprises the cursor that is installed in the turbine wheel hub and is used for driving the driver of this cursor action, and is arranged on the pivot that two ends on the wheel hub are connected with paddle with cursor respectively.
Described driver comprises servomotor and is used for driving the hydraulic package of servomotor action.Described hydraulic package is by motor and fuel tank, and constitutes by the energy-storing device that pipeline road is connected with fuel tank.Servomotor has a cylinder block and is installed in the interior piston of this cylinder body, and an end of this piston extends cylinder body, and is connected with oil pipeline respectively in the rear and front end of cylinder body.
The outside of described cylinder body is provided with displacement transducer, and the end of the shifting axle of this displacement transducer is connected with piston.The current supply line of described displacement transducer is that the central region from main shaft is input in the wheel hub.
The driver of the device that is used for adjustment water turbine paddle angle that the utility model proposes is installed in the turbine wheel hub, if this driver adopts oil pump and energy-storing device, because pipeline road is very short, cause oil to have good greasy property, its volume with oil mass and driver can reduce more than 90% compared with prior art, and oil pressure can promote more than 15, so this device fabricating cost and user cost are all relatively low; In addition, because driver is installed in the turbine wheel hub, so this device does not need civil works and hydraulic engineering design and construction, and then can further reduce production costs and fabricating cost.
Description of drawings:
