Abstract

A water flow type generator relates to a hydroelectric generation device. The rotor comprises a casing, a stator fixedly arranged on the inner ring of the casing and a rotor, wherein a rotor shaft is arranged on the casing and corresponds to the inner ring of the stator, a helical blade which extends along the axial direction is fixedly arranged on the central shaft of the rotor, and a flow guide part is arranged at the front end of the central shaft of the rotor and is in a shuttle shape. The water flow generator of the utility model has the following functions: no additional starting device is needed, so the structure of the whole generator is relatively simplified; without the assistance of extra kinetic energy, the helical blade and the central shaft are smoothly started to rotate, so that the power supply capability for output use is relatively sufficient; when the axial water flow acts on the helical blade, the assisting force for driving the water flow to axially flow towards the central shaft can be generated at the same time, so that the operation can not be completely stopped due to the reduction of the flow speed of the water flow, and the practicability is relatively high.

Description

The flow type generator

Technical field

The utility model relates to hydroelectric installation, refers to that especially a kind of torrent that utilize river flow liquid potential difference to produce water pressure promote the flow type electricity generating device of rotor running.

Background technique

Press, excessive use earth resource, to cause the exhaustion of environment and energy each side, and all human are caused greatest influence with biology, making the common people feel the darkest is exactly skyrocketing of not stopping of oil price fluctuation and the electricity charge, water rate and the cost of living, by various data display, the common people why live uneasy and future is felt to know which way to go helpless, closely bound up with the influence that the fact of the energy exhaustions is caused.

Therefore alternative energy source is there's no one who doesn't or isn't actively looked in countries in the world, how much makes contributions with the improvement to energy exhaustion, and how natural energy resources being changed and used is the part that present countries in the world are paid attention to and developed; The normal at present mode of using, main system converts electric energy to by natural energy resources such as solar energy, wind-force or waterpower, again the electric energy that is produced is exported use.

Wherein, the potential energy of utilization water and the generation mode that kinetic energy converts electric energy to are called hydroelectric power, known hydroelectric power at present has numerous embodiments, that shown in Figure 1, be a kind of known kinetic energy of water that utilizes and promote rotor 11 runnings, make its rotor 11 and peripheral stator 12 produce excitatory effect, and then reach the purpose of electric current output.

The above-mentioned hydroelectric installation of commonly using ties up to and is installed with leaf fan 13 among the rotor 11 on the axle 111, mainly utilizes the blade 131 of leaf fan 13 to accept waterpower and promotes, and drive rotor 11 rotations; Only, the blade 131 of this leaf fan 13 is according to being arranged around the central shaft periphery with identical axial position, therefore when current act on the stress surface of each blade 131 time, though each blade 131 independently the inclination angle design can make current promote 13 rotations of leaf fan, also be to hinder the resistances that leaf fan 13 rotates relatively.

Therefore, fan under the 13 static states, drive 13 rotations of leaf fan by the kinetic energy of axial current is also difficult separately at leaf; To such an extent as to, similarly commonly use that water flow generator is many can further to be provided with a starting drive, with when the generator operation, via after 13 rotations of power start axle leaf fan, the side lean on axial current to promote leaf fan 13 and central shaft 111 continues to rotate earlier.

So, make the structure composition of whole generator be tending towards complicated, the construction of relative equipment, maintenance cost are also higher; Especially, when the flow velocity of axial current was slack-off, leaf fan 13 very likely shut down, and must be again via 13 rotations of power start axle leaf fan, not only more impracticable, and must expend more electric energy for the normal operation of keeping generator, causing can be comparatively not enough for the power supply capacity of output use.

The model utility content

In view of this, the purpose of this utility model is promptly providing a kind of unnecessary via extra kinetic energy startup, and the torrent that can directly utilize river flow liquid potential difference to produce water pressure promote the flow type electricity generating device of rotor continuous running.

Take off purpose on reaching, the flow type generator of the utility model includes: casing, stator, rotor; Wherein, be installed with one among this rotor on the axle along the helical blade that extends axially configuration, when axial flow action during in helical blade, can produce one simultaneously and drive the power-assisted of current towards the central shaft axial flow, and lasting stress surface generation effect to helical blade, just can rotate at the auxiliary helical blade and the central shaft of starting smoothly down that not need extra kinetic energy.

Commonly use water flow generator and compare with preceding taking off, the flow type generator of the utility model has following effect:

1, do not need to install additional extra starting drive, simplify so the structure of whole generator is formed comparatively.

2, do not need to install additional extra starting drive, so the equipment construction of whole generator, maintenance cost are also relatively low.

3, the auxiliary of unnecessary extra kinetic energy starts the rotation of helical blade and central shaft down smoothly, so can be comparatively sufficient for the power supply capacity of output use.

4, axially flow action can produce one simultaneously and drive the power-assisted of current towards the central shaft axial flow when helical blade, shuts down fully so this is unlikely because of slowing down of flow rate of water flow, relatively than the tool practicability.

Moreover, the flow type generator of the utility model therein before the axle end be provided with the diversion division that without exception is the shuttle shape, can utilize this diversion division axial current guiding to be entered the helical blade stress area of central shaft periphery, just can effectively utilize the kinetic energy of axial current, nationality is to promote the running usefulness of generator.
