Abstract
The utility model relates to an angle gear bulb-type electric machine rotary propeller hydro generating set, which belongs to the technical field of bulb through-flow, and is to overcome defects that the set is in horizontal line layout from a water inlet via the hydro generating set to the outflow of a tail pipe, and the maintenance is difficult caused by operating under the surface of tail water surface. The utility model is characterized in that a generator is shifted to the outer part of the bulb via right-angle overdrive; the generator is higher than the surface of tail water surface and is in tandem connection with the high-speed vertical shaft end of the angle gear which is arranged in the bulb; the generator dives under upper water surface only at power-on times; the maintenance is convenient. Rotary wheels clamp blades to cooperate with revolutions by means of the displacement of central loose pieces. A built-in type actuator motor rotary propeller device is introduced. The gear bulb-type electric machine rotary propeller hydro generating set is suitable for small-and-medium-size power stations with low water heads (contain tide), and the loading capacity is from tens of kW to two or three thousands of kW.
Description
The utility model relates to scaled bulb tubular hydraulic generator category technical field.
The existing Multi-purpose bulb through-flow unit of the big flow Hydropower Unit of low water head.It all is arranged in generator, water distributor, runner and the draft tube in aqueduct, the bulb on the horizontal linear, and the blade corner of runner relies on the hydrodynamic governor of peripheral hardware to realize control.Guide vanes of water turbine hub body leading portion is expanded as bulb, interior dress generator and runner main shaft direct connection.The full subduction of unit is in the tail underwater, and only is applicable to the type of runner diameter D1 greater than 2.5m, and lid is little because of the bulb inner chamber, can not enter; So small-sized recommending with shaft extension and shaft tubular unit, make the motor can be outside water, but must adorn very lowly, machine room is wanted high fencing flood control, occurs new shortcoming again.
The purpose of this utility model aims to provide a kind of bevel gear speedup modified bulb through flow type hub bosom motor rotary propeller type Hydropower Unit, overcome the shortcoming of above-mentioned bulb through-flow unit of commonly seeing, and has a more advantage, and make runner diameter from less than 1m to greater than 3～4m, comprise that rivers and creeks low water head resource and coastal morning and evening tides resource can both be suitable for, and to changeing the unit that oar mechanism has its brand-new structure in the machine.
Be the utility model bevel gear speedup modified bulb through flow type hub bosom motor rotary propeller type Hydropower Unit that achieves the above object, except the formation with known bulb through-flow unit includes: bulb, generator, water distributor, runner and draft tube, the blade corner is adjustable, outside the operation of unit diving, its feature: the one, submergence type vertical shaft generator is separated in bulb, and the right angle is series at the bulb top; The 2nd, this submergence type vertical shaft generator unit stator winding has been designed to two kinds of numbers of pole-pairs, double winding has been arranged when being used in tidal power station, thereby has the induction generator of fast, slow two kinds of rotating speeds; The 3rd, the multi-disc blade around the runner hub is by each cake band cam pin, and make its each guide be clamped in the center to have in the fluted loose piece of screw periphery, constitute the multicrank connecting rod means, rely on the forward and backward of center bolt, the collaborative corner of many blades is transferred in displacement before and after loose piece is followed; The 4th, dispose the interrupted power supply of two-direction switch that operating motor and retarder rely on computer speed regulator modulation on the distribution board in the draft cone behind the runner hub and send into bulb and connect brush, collector ring through cable and pass hollow spindle and go into the motoring retarder and make the center bolt clockwise and anticlockwise.
Advantage of the present utility model has:
Because generator has been taken out in bulb, only adorn bevel gear pair in the bulb, outer water cooling condition spy excessively is good for bulb, and the gear running noises to be water body isolate guarantees quiet on the machine room of water power plant, and motor is through the bevel gear speedup, the rotating speed height, and size is little, several times fall in cost, occupy again on the tail water face, maintenance is convenient, just diving operation after only opening a sluice gate, the submersible motor cool condition is good, allows overload and do not have flood control necessary.And bulb and motor housing are standstill seal, do not have the trouble of infiltration.Motor is not chosen into the bulb maintenance, so the runner size is little greatly by it outside bulb more.Both can replace medium-sized bulb unit, can replace shaft extension and shaft tubular unit again; And especially big at tidal power station head luffing, with the induction generator of change pole double speed winding to adapt to it, can be multiple.The built-in operating motor of newly-designed in addition runner hub changes the oar device, and it and retarder are included in runner hub chamber and the draft cone hydrodynamic governor that saves a whole set of peripheral hardware again simple in structure to the greatest extent with accent oar mechanism.This new unit will doubly be reduced investment outlay than the conventional light bulb through-flow machine composition of exerting oneself identical.
Concrete structure of the present utility model is seen accompanying drawing 1～4
Fig. 1 is the installation diagram of bevel gear speedup modified bulb through flow type rotary propeller type Hydropower Unit, the current that open the sluices pour in and have flooded submersible electric generator and walk around bulb and order about the runner disease through stator and change and to fall progressively into the downstream through the draft tube flow velocity, and runner can be converted into mechanical energy with water and drives generator for electricity generation through the bevel gear speedup.
Fig. 2 is the sectional view of (3) feathering vane runner assembly among Fig. 1.
Fig. 3 carries out the Induction Motor Structure figure of speed governing with tapered rotor for (22) among Fig. 2.
Fig. 4 and Fig. 5 are the structural drawing of (23) retarder among Fig. 2.
In Fig. 1 installation diagram: (1) circle-square type draft tube front end and (2) are the runner envelope of the subdivision connection of living up and down, chamber front end (4) water distributor the place ahead welding (14) bulb again that is spirally connected; (3) feathering vane runner assembly the place ahead in runner envelope connects firmly (8) hollow spindle and passes (5) sealing sealing, (6) (7) in the water conservancy diversion hub and radially reach in (15) marine riser that (10) connecting shaft camber line bevel pinion that key behind the double thrustbearing (9) camber line bevel gear wheel and its engagement is spirally connected by the bulb top with (16) coupling speedup transmission (17) submersible electric generator and to manage and adorn (20) cable and pass the distribution board transmission of electric energy of the water surface on machine room; Pass (8) hollow spindle and insert (22) motor in (21) draft cone through (25) runner hub is inboard and insert (32) cable among Fig. 2 via (11) cable in (18) cable protecting tube through (13) brush (12) collector ring through the interrupted power supply that makes the built-in execution of (3) feathering vane runner assembly change the motor clockwise and anticlockwise of oar mechanism of (19) computer speed regulator modulation output.
