Description

HYDROELECTRIC GENERATION DEVICE USING THE NATURAL FLOWS
Technical field
The present invention is related to hydroelectric generation device using the water power of the natural flows such as the current of the rivers, waterfalls, tide.
Background of the invention
Up to this time, there are many hydroelectric power stations used water power base oh principle of banking, building aqueduct and irrigating water via turbine to drive generator.
The flow of rivers will be effected by banking and building aqueduct, it could effect to agriculture cultivation; especially the broken dam can damage economic and welfare of people.
To make use of water energy, we can use flow of rivers, streams, tide and waterfalls to drive generator without banking or impounding.
Summary of the invention
The objective of the present invention is to propose hydroelectric generation device which makes use of the water power of the natural flows.
To archive the above objective, the hydroelectric generation device comprises:
- a waterwheel provided with a rotary shaft at the center of the waterwheel,
- bucket supporting bars having one end connected firmly to the waterwheel and arranged regularly and radialy on the circumference of the waterwheel,
- buckets mounted to the other end of the bucket supporting bars, each bucket has V-shaped section, and bucket mouths are put as the same direction, parallel with rotary shaft and opposite to the flow,
- pillars having ball bearing arranged to support the rotary shaft,
- power generating means is driven directly by the rotary shaft or through transmission system. Brief description of the drawings
The invention will be understood clearly by this overview with enclosed figures:
Figure 1 is a perspective view of the hydroelectric generation device according to the first embodiment of the invention.
Figure 2 Illustrates how to connect the bucket to the bucket supporting bar according to the first embodiment of the invention.
Figure 3 a perspective view of the hydroelectric generation device according to the second embodiment of the invention.
Figure 4. a perspective view of the hydroelectric generation device according to the third embodiment of the invention.
Detailed description of the invention
The present invetion will be described in detail according to illustration figures.
Figure 1 illustrates generator according to an embodiment of the invention. The hydroelectric generation device according to this embodiment, comprises the components as following. A waterwheel A provided with a rotary shaft XX at the center of it. Bucket supporting bars 2 which have one end connected firmly to the waterwheel A and arranged regularly and radialy on the circumference of the waterwheel A. Buckets 1 are mounted to the other end of the corresponding bucket supporting bars 2. Each bucket 1 has V- shaped section. The mouths of buckets are put as the same direction, parallel with rotary shaft and opposite to the flow. Two pillars B with ball bearings 3 are arranged to support the rotary shaft XX. The pillars B must be high enough so that the waterwheel A is always above the water surface. A power generating means M is driven directly by the rotary shaft XX or through transmission system 4.
The V shape section of the buckets result in the increase of the contact area while reduce the resistance between the buckets and the water, so that the energy received can be maximized.
Figure 2 illustrates a bucket is mouted on the bucket supporting bars 2 in the manner that it's length can be adjusted in compliance with the change of water level of the flows in different times and places. Such as in dry season, supporting bars can be stretched; in contrast, in rainy season, it can be retracted so that buckets are under suitable depth to get maximum energy of the flow as well as reduce the resistance.
In case the change of the water levels is over controllability of the bucket supporting bars, the height of pillars B is also adjusted as shown Figure 3. The pillars B also can be adjusted to other directions on the horizontal to fit with the movement of flow.
Figure 4 illustrates hydroelectric generation device according to another embodiment of the invention using power of tide. The tidy flows will flow via the conduit system 7, 8 which is supported by the support 6. The flow will be irrigated into conduit 7 and impact into buckets 1 so that the rotary shaft will be rotated to drive generator.
Persons skilled in the art can be appreciated that the size of waterwheel, buckets, the length of bucket supporting bars, rotary shaft and bearing pillars can be adjusted and changed to fit with water level, which can be changed from few meters to tens of meters.
