Description
Technical field
The utility model relates to a kind of hydraulic turbine generator.
Background technique
Existing hydraulic turbine generator is made up of generator and water turbine, and water turbine is made up of volute, sharf and blade again.This hydraulic turbine generator must have enough heads, as 8 meters of above heads could normally be worked, thereby has greatly limited the occasion of its application.Many rivers and irrigation canals and ditches in rural area just cannot be applied, and at least, the in the situation that of low water level and low water head, its working efficiency and generating capacity are undesirable.
model utility content
Task of the present utility model is to provide a kind of low water level that can still can normally work without cessation the in the situation that of low water level and low water head often to rotate hydraulic turbine generator.
Task of the present utility model completes like this: it is by frame, water wheels, speed changer, generator, motor, water pump, water pipe, tank and composition, water wheels are installed in frame, speed changer, generator, motor and water pump, water wheels cylindrical is fixed with 60 uncovered outside water tanks, water wheel axle is connected with the input shaft of speed changer by coupling, the output shaft of speed changer is connected with generator shaft by coupling, motor reel is connected by belt transmission with water pump spindle, the intake pipe of water pump is connected with tank, the outlet pipe mouth of pipe of water pump is placed in the water tank top at water wheels top, the output voltage of generator is identical with the input voltage of motor after boosting.
The speed changer two-stage speedup speed changer that preferably velocity ratio is 100 to 1.The rated speed of generator is per minute 100 to turn.The voltage rating of motor can be 220 volts.
Because the utility model is fixed with 60 uncovered outside water tanks at water wheels cylindrical, water wheel axle is connected with the input shaft of speed changer by coupling, the output shaft of speed changer is connected with generator shaft by coupling, motor reel is connected by belt transmission with water pump spindle, the intake pipe of water pump is connected with tank, the outlet pipe mouth of pipe of water pump is placed in the water tank top at water wheels top, and the output voltage of generator is identical with the input voltage of motor after boosting.The river and the irrigation canals and ditches that the utility model are applied in to low water level and low water head, still can normally work without cessation, and can make full use of existing resource, for society provides the energy endlessly.
Brief description of the drawings
Fig. 1 is the schematic diagram of an experimental setup of the utility model.In figure: 1-frame, 2-water wheels, 3-water tank, 4-tank, 5-speed changer, 6-generator, 7-motor, 8-water pump, 9-intake pipe, 10-outlet pipe.
Embodiment
Referring to accompanying drawing 1, the water wheels 2 of 10 meters of diameters are installed in the frame 1 of the utility model experimental setup.Also can two in parallel uses of water wheels.The cylindrical of water wheels 2 is fixed with 60 uncovered outside water tanks 3.The volume of each water tank is 1 cubic metre.It is the tank 4 of 30 cubic metres that there is a capacity below of water wheels 2.Speed changer 5 and generator 6 are also installed in frame 1.The input shaft of water wheel axle and speed changer connects by coupling (not shown in FIG., lower same), and the output shaft of speed changer is also connected by coupling with generator shaft.Speed changer 5 is that velocity ratio is about 100 to 1 two-stage speedup speed changer.The velocity ratio maximum of the first order can be 30 to 1, and the velocity ratio of the second level is 3.33 to 1.Also can be by other velocity ratio configuration.The rated speed of generator 6 be per minute 100 turn, 650 kilowatts of power.Motor 7 and water pump 8 are also installed in frame 1.The voltage rating of motor 7 is 250 kilowatts of 220 volts, power.The lift 20-25 rice of water pump 8, flow are 3600-4000 cubic meter per hour.Motor reel is connected by the belt transmission of v belt or flat belt with water pump spindle.The intake pipe 9 being connected with the water intake of water pump 8 is connected with tank 4.The mouth of pipe of the outlet pipe 10 being connected with the water outlet of water pump 8 is arranged at water tank 3 tops at water wheels 2 tops.The output voltage of generator 6 is identical with the input voltage of motor 7 after boosting.
Before start, first use diesel engine (not shown in FIG.) to drive water pump 8 to rotate through motor 7, or directly drive water pump 8 to rotate with diesel engine, by the water of 4 li of tanks, be pumped in the water tank 3 at water wheels 2 tops, allow water wheels 2 rotate, and water is injected in turn to the water tank at other top of passing through, along with water wheels 2 rotational speeies are accelerated gradually and reach per minute 1 while turning, generator 6 reaches its rated speed, i.e. generating, the outwards output of electricity part that generator 6 sends, part supply motor 7, drive water pump 8 draw water.Said apparatus is applied to river and the irrigation canals and ditches of low water level and low water head, river and irrigation canals and ditches are as tank and auxiliary power, and generator can normally ceaselessly turn round.
