Fig. 3, be the utility model impeller construction schematic representation.
Among the figure, 1, impeller, 2, bearing support, 3, gear-box, 4, tachometer, 5, generator, 6, forward spindle, 7, pedestal, 8, ground, 9, spoke, 10, blade, 11, wheel hub, 12, wheel shaft, 13, the back main shaft.
Embodiment
Accompanying drawing is the utility model embodiment, below in conjunction with drawings and Examples the utility model is described: blade 10, wheel hub 11, spoke 9 and wheel shaft 12 organically are fixed with one and form impeller 1, arc shaped blade 10 more than at least 10 is fixedly set in wheel hub 11 peripheries, the spoke 9 that is no less than 15 is solidly connected wheel hub 11 and wheel shaft 12, be solidly connected by wheel shaft 12 and forward spindle 6 bolt types, impeller 1 integral body is rotated synchronously with forward spindle 6.Pedestal 7 is disposed with the fixed installation position of bearing support 2, gear-box 3, tachometer 4, generator 5, the forward spindle 6 that rotates synchronously with impeller 1 passes through the support of bearing support 2 with stable, extend to gear-box 3, main shaft 13 further extands rearward to 5 rotors with generator 5 of generator through tachometer 4 and is connected after the speed change of gear-box is quickened.Gearwheel in forward spindle 6 and the gear-box 3 is connected, and back main shaft 13 is connected with the small gear of gear-box 3, and front and back spindle speed is than 5-10 times of improve.
Further specify below in conjunction with this designing requirement and working principle of installing concrete parts, as shown in Figure 1, one, main shaft portion, adopt bolt to connect between impeller 1 and the forward spindle 6, wheel hub 11 needs a middle flange to be connected with flange plate on the forward spindle 6, and the intensity of bolt and forward spindle 6 will be within certain water hammer load.Forward spindle 6 from impeller 1 to generator 5 and back main shaft 13 are two very long axles, thus the rigidity of axle to get well, in order to prevent that in rotary course the distortion of the beat of main shaft has been installed bearing support 2 between impeller 1 and gear-box 3.Not only played supporting effect, guaranteed that also the rotation of axle is flexible.Two, gear-box 3, it is a main shaft accelerating unit, the speed per second that water impact (as Fig. 3 arrow direction) impeller 1 is rotated only has 1-2 to change, and it is very low that such spindle speed is carried out generating efficiency, in the direction of the main shaft output speed of impeller 1 a gear accelerating unit is installed.The output speed of main shaft can be improved 5-10 doubly, so just can improve the working efficiency of generator greatly, the back main shaft 13 after acceleration will be installed the instrument 4 that tests the speed, and be used for showing its rotating speed, and calculate the generated energy of this device output.Three, impeller part, wheel hub 11 is connected transmitting torque with forward spindle 6; 24 spokes 9 can connect wheel hub 11 and wheel shaft 12, play a supporting role; Blade 10 is connected on the wheel hub, and blade 10 is subjected to power to be delivered on the wheel hub 11 after the water impact, and then converts moment of torsion to, and forward spindle 6 is rotated; Blade 10 parts are used to accept impact force of water flow, and blade 10 areas are too small, and the strength that water strikes on the blade is less, and wheel hub 11 driving torques are not enough.Blade 10 is excessive, and impeller 1 deadweight increases, and rotates dumbly, so the design of blade is very crucial, not only want solid reliably, shock-resistant, also to meet the flowing water principle of dynamics, can be in the certain excursion of current continuous firing.
Below in conjunction with installation and application this device is described:
At first accomplish fluently rectangular cement ground 8 in the maximum drop place in river, direction is perpendicular to current direction.Mounting base 7 on cement ground 8.To support pedestal 7 steadily, and be connected firmly with the cement ground.In the anterior installation shaft bearing 2 of pedestal 7, bearing support needs fixation.On the bearing support direction in hole will with the base direction always, guarantee that forward spindle 6 can pass through bearing smoothly, and rotate flexibly, at gear-box 3 of top, pedestal 7 the place ahead installation.Gear-box 3 must be an acceleration mechanism, and forward spindle 6 is connected by bearing support 2 Large Gear Shaft During direct and in the gear-box 3.By gear shift, improved the rotating speed of main shaft.
Secondly a tachometer 4 being installed from the gear-box 3 back main shafts that are connected with small gear 13 that stretch out, tachometer is used for measuring spindle speed, be convenient to whole unit is controlled, least significant end at back main shaft 13 is installed generator 5, generator will be installed in the last of base, be connected firmly with base, back main shaft 13 is connected with generator amature.The impeller part is installed at last, and the spoke 9 on the impeller 1, blade 10, wheel hub 11, wheel shaft 12 have been present in an integral body, and the impeller flange is connected foremost with forward spindle 6.This device is all installations just.
The 3rd operation, mounted impeller is placed water, current impact blade 10 from top to down, and blade is subjected to being delivered on the wheel hub 11 after the power, and wheel hub produces moment of torsion to begin to rotate, the wheel hub rotation will drive main shaft 6 and rotate, main shaft supports and balance by bearing support 2, and by gear-box 3 acceleration mechanisms, has improved spindle speed, the main shaft of faster rotational speed directly is connected with generator, just can generate electricity.Tachometer between generator and the accelerator is used for detecting spindle speed.Can implement to detect to power generation process.
