course, so they are easy to get damaged by collision resulted from river
objects. Moreover, the buoyed electricity power generation device is
easy to get damaged by vapor-phase oxidation.
From the above descriptions, although the buoyed electricity
power generation device can generate electricity, its output cannot be
improved and it is easy to get damaged by river flushing. Therefore,
improvements are desirable to be obtained.

With reference to depicting the state that the water wheel
42 is buoyed up on the flow 2 in low water level, the leverage caused by
the first propeller set 51 with fulcrum of the holder 32 is provided by the
second propeller set 52, and the included angle θ becomes large. The
rotating energy of the water wheel set 42 is still able to be transmitted to
the generator 61 by the mobile energy transmitting unit 5 for generating

With reference to depicting the state that the water wheel
42 floats on the flow 2 in high water level, the leverage caused by the
first propeller set 51 with fulcrum of the holder 32 is provided by the
second propeller set 52, and the included angle θ becomes small. The
rotating energy of the water wheel set 42 is still able to be transmitted to
the generator 61 by the mobile energy transmitting unit 5 for generating
electricity.
Two sets of generator 61 are able to be driven by the water wheel
set 42 in the present invention, two mobile energy transmitting units 5
are necessary to be respectively disposed on the right and left sides of
the water wheel set 42, so the energy of the flow 2 is transmitted to the
platform31, and then two generators 61 are respectively disposed for
generating electricity.
With reference to a second preferred embodiment device of
present invention is provided. Because the second embodiment is
similar to the first, common features are not described again. A
difference is that the mobile energy transmitting unit 5 comprises a first
propeller wheel 541 disposed in the water wheel axis 422, a second
propeller wheel 542 disposed on the holder 32, a first propeller unit 543
coupled to the first and the second propeller wheels 541, 542, a third
propeller wheel 544 disposed on the holder 32 and rotated
simultaneously with the second propeller wheel 542, a fourth propeller
wheel 545 disposed in the generator axis 611, and a second propeller
unit 546 coupled to the third and the fourth propeller wheels 544, 545.
The first propeller wheel 541 is rotated simultaneously with the
water wheel blade 421, the second and third propeller wheels 542, 544
are rotated simultaneously, and the fourth propeller wheel 545 is rotated
simultaneously with the generator axis 611 of the generator 61. The
circumference of the first and the second propeller wheels 541, 542 are
encircled at the same time by the first propeller unit 543, so that the
second propeller wheel 542 is rotated by obtaining the energy of the first
propeller wheel 541. The circumference of the third and the fourth
propeller wheels 544, 545 are encircled at the same time by the second
propeller unit 546, so that the fourth propeller wheel 545 is rotated by
obtaining the energy of the third propeller wheel 544.
When the water wheel unit 4 is turned to rotate by the flow 2, the
energy of the flow 2 is transmitted to the generator 61 to generate
electricity by the mobile energy transmitting unit 5. When in practice, the
generator axis 611 of the generator 61 has a direct linkage with the
second propeller wheel 542 to achieve the purpose of generating
electricity without usage of the third and fourth propeller wheels 544, 545
and the second propeller unit 546.
In the second preferred embodiment device of present invention,
the circumference of the first propeller wheel 541 is bigger than the
second propeller wheel 542, while the circumference of the third
propeller wheel 544 is bigger than the fourth propeller wheel 545, so that
the rotational speed of the generator axis 611 can be risen up and the
electricity generating frequency of the generator 61 can be speeded up.
Preferably, the rotational speed of the first propeller wheel 541 is slow
but with big torsion, the chain is used by the first propeller unit 543, and
the gear wheel adapted to the first propeller unit 543 is used by the first
and the second propeller wheels 541, 542. While the rotation speed of
the generator axis 611 is faster, the continuous belt is used by the
second propeller unit 546, so that the fourth propeller wheel 545 is
turned to rotate via the third propeller wheel 544, and the amount of the
continuous belt is determined by the energy. When in practice, the first
and the second propeller units 543, 546 are optional adapted to different
situations and it shall not be construed as limiting the invention.
In addition, the cross-section view of the water wheel blade 421 of
the water wheel set 42 is a V shape, and the included angle of the V
shape heads to the direction of the flow 2, so that the flowing force of the
flow 2 can be focused on the water wheel blade 421. Preferably, the
included angle of the V shape in every water wheel blade 421 is between
100° and 140°, so the maximum thrust of the flow 2 can be obtained.
Furthermore, the retaining sheets can be disposed next to the both sides
of the water wheel blade 421, so the thrust of the flow 2 can be
accumulated efficiently.
With the description of foregoing preferred embodiments, the
following benefits of the present invention can be obtained:
1. The floating set 41 is buoyed up on water, so that the water
wheel unit 4 and the flow 2 are remained in contact state. No matter the
flow 2 is in high or low water level, the water wheel blade 421 is able to
be rotated by the flushing of the flow 2.
2. Following the previous description, the supporting set 43
following the direction of the flow 2 is extended at a downward angle,
and an included angle θ is formed between the surface of the flow 2 and
the supporting set 43, so that the water wheel blade 421 is rotated by the
downstream flowing of the flow 2.
3. Because of the buoyance of the first and the second floaters 411,
412, the water wheel blade 421 is buoyed up on water, and moreover,
the bottom of the first and the second floaters 411, 412 are designed as
the boat shape 416. The first and the second floaters 411, 412 are pulled
by the ropes 415, and their surfaces toward the direction of the flow 2 are
designed as the boat shape 416, so that the flow 2 can be diverted to
reduce the shaking of the water wheel blade 421 caused by turbulences.
4. The mobile energy transmitting unit 5 is rotated in a variable
angle along the sixth gear wheel 531 by the fifth gear wheel 523 of the
second propeller set 52. Therefore, no matter the first propeller set 51 is
in low or high water level, it can be meshed with the third propeller set 53,
and the rotation energy of the water wheel unit 4 can be continuously
transmitted to the electricity power generating unit 6 for generating
electricity.
In conclusion, with the present invention, the water wheel blade
421 is buoyed up on water via the floating set 41, and is rotated by
obtaining the flushing of the flow 2, and moreover, the generator axis 611
is turned to rotate via the mobile energy transmitting unit 5 adapted to
the water level, so that the generator 61 can generate electricity. The
water wheel blade 421 is stabilized by the boat-shaped floating set 41 to
obtain the energy of the flow 2, and is separable to be coupled to the
floating set 41, so it can depart from the floating set 41 for maintenance,
and be coupled to the floating set 41 when generating electricity.
Therefore, the objectives of the present invention can be obtained.
The foregoing detailed description is merely in relation to two
preferred embodiment devices of the present invention, and shall not be
construed as limiting the invention. It is to be understood that many other
possible modifications and variations can be made without departing
