The present invention relates generally to a tower-based power generation method and a device thereof, and more particularly to a tower-based power generation method and a device thereof that generates electrical power through water impacting a power generator unit so that a circulative operation may be achieved for successively generating electrical power without starting power supplied externally.
The continuous consumption of natural resources of the Earth brings a severe issue of global warming and also leads to a potential concern of exhaustion of the natural resources. Most of the countries started projects of generating electrical power in a “natural” way. The general ways of generating electrical power naturally include hydraulic power, wind power, solar power, and nuclear power. Taking hydraulic power as an example, a dam or reservoir must be constructed first. This is costly and can only be built in a suitable site, making it hard to be widely used. Considering wind power generation, a high tower must be built and large-sized blades or vanes must be installed on the top of the tower. The cost is also high and the facility must be constructed in areas that are windy year round. This is not fit for areas where winds are weak.
For solar energy, the cost is generally high and the installation is conditioned by long term sun shining. As such, the performance of power generation is unhandlable but the cost is high. As to nuclear power, although it is considered clean energy, safety and long term contamination of the Earth are the concerns and are constantly doubted and opposed by the environmentalists.
In view of these, the present invention aims to provide a tower based power generation device, which generates electrical power through water impacting a power generation unit to thereby achieve protection of the environment.
The primary object of the present invention is to provide a tower-based power generation method and a device thereof, which generate electrical power through water impacting a power generation unit so that a circulative operation may be achieved for successively generating electrical power without starting power supplied externally and thus help protecting the environment.
The tower-based power generation method and device uses two buckets that are movable alternately up and down to carry water to an upper location to allow water to rush down to impact and drive power generation units to generate electrical power and thus achieving circulative power generation.
In the above tower-based power generation method and device, a tower frame is provided. The tower frame comprises a first bucket and a second bucket mounted thereto to be driven and moved by a drive unit. The tower frame has a bottom in which a water storage trough is formed. Rotary mechanisms are arranged above the water storage trough. The rotary mechanisms are coupled to the power generation units. Two sides of the tower frame are each provided with a water storage tank. The water storage tank has a bottom from which a pipe extends to a location above the respective rotary mechanism. The drive unit drives the first bucket and the second bucket to alternately move up and down to carry water from the water storage trough to the upper part of the tower frame to be poured into the water storage tanks, allowing water to flow down along the pipes to impact and drive the rotary mechanisms and thus drives the power generation units to generate electrical power. Water that flows down the pipes is allowed to flow back into the water storage trough for circulative power generation.
In the above tower-based power generation method and device, stop pieces are respectively arranged at locations above the water storage tanks of the tower frame, so that when the buckets are driven to the locations of the stop pieces, the engagements of the stop pieces with the buckets cause the bucket to rotate by an angle to pour water into the water storage tanks.
In the above tower-based power generation method and device, the drive unit is mounted to a top of the tower frame to rotate forwards and backwards for driving the buckets to move up and down.
In the above tower-based power generation method and device, the first bucket and the second bucket each have a bottom having an inside surface on which a retention member is mounted. A valve plate is rotatably coupled to the retention member so that the valve plate is made movable with the retention member being a support point. When the first bucket or the second bucket is dipped into the water storage trough, water pressure causes the valve plate to move upward and disengage from an opening to allow water to flow through the opening into the first bucket or the second bucket, which when filled up with water, generates a water pressure therein and the valve plate is pushed down to get fit into the opening, preventing water from flowing out of the first bucket or the second bucket thereby achieving an effect of holding water therein.
The foregoing objectives and summary provide only a brief introduction to the present invention.

The first bucket 2 and the second bucket 3 are each provided with an inverted U-shaped handle 21, 31 in such a way that two ends of the handle 21, 31 are respectively and pivotally connected to opposite sides of the bucket 2, 3 to show a movable arrangement therebetween and each bucket has a bottom wall in which an opening 22, 32 is formed and comprises a retention member 23, 33 mounted to an inside surface of the bottom wall in such a way that the retention member 23, 33 is rotatably coupled to a valve plate 24, 34 to allow the valve plate 24, 34 to show a movable arrangement with the retention member 23, 33 being a support point so that the valve plate 24, 34 is selectively movable into and thus close ; the opening 22, 32 or is movable upward to disengage from the opening 22, 32. A stop plate 25, 35, which extends horizontally from a side wall of the bucket 2, 3, is provided above the valve plate 24, 34.
The tower frame 1 has two opposite sides on each of which a water storage tank 6 is provided. An inclined water chute 61 is arranged above the water storage tank 6. A stop piece 62 that is inclined is provided above the water chute 61. The water storage tank 6 has a bottom from which a pipe 63 extends to a location above the rotary mechanism 2.
With the above arrangement of the components, a tower-based power generation device is formed. The drive unit 11 drives the first bucket 2, the second bucket 3 to move in such a way that, with the first bucket 2 and the second bucket 3 being counterweight of each other, the first bucket 2 the second bucket 3 are alternately moved up and down to carry water from the water storage trough 13 to a location at an upper part of the tower frame 1 to be poured into the respective water storage tanks 6, whereby water received in the water storage tanks 6 is allowed to rush down along the pipes 63 to impact and drive the rotary mechanisms 4 to rotate and thus drive the power generation units 5 to generate electrical power. The electrical power generated by the power generation units 5 is partly supplied to the drive unit 11 mounted atop the tower frame 1, while the remaining electrical power can be supplied to various sorts of electrical appliances that are not shown in the drawings. Water that flows down along the pipes 63 is then allowed to flow back into the water storage trough 13 to achieve an effect of circulative power generation and an effect of environmental protection.
