Working principle of the present invention:
According to the flow velocity of water in the runoff process, the kinetic energy promotion water wheels rotation that flow produces; Water wheels are transformed into mechanical energy with the kinetic energy of current; Because of connection through swing arm and continuous motion stem; Drive the transmission shaft rotation when making gearwheel, middle Jie's gear, pinion rotation, drive the generator rotary electrification through clutch, planet gear speed increaser and variable-speed hydraulic governor again.Through planet gear speed increaser the slow-speed of revolution of water wheels is increased to about the rated speed 750r/min that generator should need.Through the open angle controlled water flow of spoiler amount; Control just is applied to the size of the kinetic energy of water wheels, rotating speed is controlled in the speed range of generator permission, and this is the coarse adjustment of revolution; The fine tuning of revolution is implemented by variable-speed hydraulic governor, and process thick, fine tuning is such:
Tachogenerator is input to the transmission shaft revolution signal that records the input end of the line style amplifier chip U1 in the control cabinet; The output signal of its both-end is input to the respective ends pin of cpu chip U3; Calculation process through cpu chip U3; If the signal of cpu chip U3 output was transported to the double-piston hydraulic oil cylinder through I/O I/O chip U4 and power amplifier module U5 and makes left and right spoiler open rotation relatively when revolution was low; Thereby water flow is increased, and the impact force that water wheels receive will and then strengthen naturally, and revolution will promote.If cpu chip U3 output opposite signal relatively rotated left and right stepper motor when revolution was high, drive the closed relatively rotation of left and right spoiler, thereby water flow is reduced, the impact force nature that water wheels receive is just little, and revolution will lower.
Another group output signal of cpu chip U3 is added to the control end of variable-speed hydraulic governor through I/O I/O chip and power amplifier level, makes the signal magnitude that its foundation sends here and regulates revolution automatically.
Fluviograph is input to the water level signal that records the input end of No. two chip U2 of line style amplifier in the control cabinet; Its output signal is input to cpu chip U3, and through the calculation process of cpu chip U3, the signal of cpu chip U3 output can make hydraulic press open the output high pressure oil when low as if water level; Last filler opening oil-feed from the first from left, the second from left, the right side one and right two hydraulic jacks; Thereby four hydraulic jacks are moved respectively, and reduce left and right two walking beams, and then the drive water wheels sink in water; Thereby water flow is increased, and the impact force that water wheels receive will and then strengthen naturally; If whole process was just in time opposite when water level was high.
The radial-flow water wheel generator set is a kind of electricity generating device that designs invention to the river of domestic low water head nature flowing water.Be applicable to that natural river and water power plant go out terminal installation of water channel and generate electricity; Its major character is through spoiler and variable-speed hydraulic governor control transmission shaft revolution; Adopt the hydraulic mechanism elevator mechanism can ensure that whole generating unit long-term safety normally moves; But both manual tune, practicable again automatic control and adjustment.Can pass through gearwheel, middle Jie's gear, small gear and between the zip mode water wheels elevator mechanism formed of the continuous motion stem that connects and swing arm, adjustable water wheels are left the water, water wheels diameter and machine group length can be according to the river degree of depth and highly definite.Generated output is at 70kw-1000kw.Water wheels adopt the arc line type working surface, increase the gravity of water, reduce water resistance.
Whole system is simple in structure, and is easy to utilize.
Characteristics of the present invention:
1, economic benefit is huge: domestic water turbine generator group generating at present, need to build reservoir and checkdam, the construction period is long, investment is big, the investment of domestic water plant generator on average every kilowatt about 10,000 yuan.To build 100 kilowatts of hydraulic turbine generators is example, needs about 1,000,000 yuan of investments, and the seepage flow generator set only needs about 250,000 yuan, be 1/4 of hydropower investment volume, and building time shortens greatly.
2, ecological benefit are huge: normal hydraulic generator unit generating must be built reservoir or dykes and dams; Building of reservoir and dykes and dams must bring the cutout of downstream, river course; Thereby influence and destroy the natural, ecological in its downstream, in a single day ecotope destroys and is unbalance, and some can't recover.The advantage of seepage flow hydraulic turbine generator generating is one not destroy environment, the 2nd, do not destroy ecology, and it is the effective utilization to the waterpower resourses power that wastes.
3, social benefit is huge: the firstth, help social stability, and this equipment need not be migrated, without moving population; The secondth, increase social generated energy, help the national economic development of country; The 3rd is to help local economic construction, increases local rates, increases local personnel's employment, improves local people's living standard.
4, spoiler is the characteristics and the advantage of this equipment through the automatic control mechanism control water yield and flow velocity.
5, the present invention adopts speed regulating mechanism, makes revolution reach the requirement of generator, improves stability.At present domestic still do not have this technical application in the radial-flow water wheel generator set.
The present invention compares advantage with existing similar generator set and is: facility is simple, and construction is exempted the great engineering that the construction of general power station is gone to war easily; Little investment, cost is low, and daily being convenient to safeguarded; Be convenient to management, it is less to drop into manpower, design science of the present invention, reasonable, original; Compact structure, tight, stable and reliable for performance, easy and simple to handle, have a development prospect preferably.Be suitable for and the rural area, mountain area and the generating of area, the region of rivers and lakes are used.
