Detailed ways

The detailed description and technical contents of the present application are described as follows in conjunction with the accompanying drawings. However, the attached drawings are only provided for reference and explanation and are not intended to limit the present application.

Please refer to FIG. 1 , the present application provides a seesaw-like hydroelectric power generation device, which mainly includes a long box body 10 , a hydro-generator set 20 , a fulcrum structure 30 and a jacking mechanism 40 .

The cross section of the elongated box 10 can be rectangular, oval, circular or other various geometric shapes, and it has a cavity 11, a partition 12 is provided in the cavity 11 to separate a first chamber 13 and a second chamber 14, and a water flow channel 15 connecting the first chamber 13 and the second chamber 14 is provided below the partition 12. The partition 12 is located in the middle of the cavity 11, so that the volumes of the first chamber 13 and the second chamber 14 are equal. In addition, the first chamber pulling point 16 and the second chamber pulling point 17 are respectively provided at the two corner ends of the top of the elongated box 10.

The hydro-generator set 20 mainly includes a generator 21 and an impeller 22 connected to the generator 21 . The impeller 22 is disposed in the water flow channel 15 and has a plurality of turbine blades, so that the rotation of the impeller 22 drives the generator 21 to generate electricity.

The fulcrum structure 30 is arranged below the elongated box body 10 and is located in the middle of the elongated box body 10, and is formed directly below the aforementioned partition 12. The fulcrum structure 30 mainly includes a support seat 31, an angle plate 32 and a bearing 33. The support seat 31 is fixed on the lower platform DP, the angle plate 32 is fixed on the bottom surface of the elongated box body 10, and the angle plate 32 is connected to the support seat 31 through the bearing 33.

The lifting mechanism 40 of this embodiment is a pair of springs 41, 42, which are respectively arranged on both sides of the fulcrum structure 30. In addition, the lifting mechanism 40 can also be an oil pressure device, a pneumatic device or other force-applying device.

In one embodiment, the seesaw-like hydroelectric power generation device of the present application also includes a lifting mechanism 50 (LD, Lifting Device), which is arranged above the elongated box 10 and connected to the elongated box 10. The lifting mechanism 50 is a labor-saving mechanism. Through the configuration of the movable pulley, the lifting force to pull up the elongated box 10 can be much smaller than the weight of the working fluid WF. Therefore, the working fluid WF can be lifted and flipped with less energy. It is a mechanism that consumes low energy but generates high energy.

The lifting mechanism 50 mainly includes a first pulley group 51 and a second pulley group 55. The first pulley group 51 is arranged on the upper left side of the elongated box body 10, and it mainly includes a fixed pulley 511, two movable pulleys 512, a first motor 513 and a pull rope 514. The fixed pulley 511 is fixed on the upper platform UP. The first motor 513 is connected to the fixed pulley 511 and each movable pulley 512 through the winding of the pull rope 514. The movable pulley 512 is connected to the first chamber pulling point 16 of the elongated box body 10, so as to achieve a labor-saving effect.

Similarly, the second pulley group 55 is arranged on the upper right side of the elongated box 10, and it mainly includes a fixed pulley 551, two movable pulleys 552, a second motor 553 and a pull rope 554. The fixed pulley 551 is fixed on the upper platform UP, and the second motor 553 is connected to the fixed pulley 551 and each movable pulley 552 through the winding of the pull rope 554, wherein the movable pulley 552 is connected to the second chamber pulling point 17 of the elongated box 10.

In addition, the number of the movable pulleys 512, 552 is not limited to the two shown in the figure, but may be three or more to achieve a better labor-saving effect.

Please continue to refer to Figure 2, where:

L1: The force arm from the pulling point of the first chamber to the fulcrum LB1: The force arm from the center of gravity of the left box to the fulcrum LF1: The pulling force of the first pulley group on the long box LF11: The pulling force of the first motor

WB1: Left box weight

CG2: Center of gravity of the right side box CGW2: Center of gravity of the right side working fluid

L2: The force arm from the pulling point of the second chamber to the fulcrum LB2: The force arm from the center of gravity of the right box to the fulcrum LF2: The pulling force of the second pulley group on the long box LF22: The pulling force of the second motor

LS2: The force arm from the right spring to the fulcrum

LW2: The force arm from the center of gravity of the working fluid on the right to the fulcrum SF2: The force of the spring on the right

WB2: right box weight

WW2: right side working fluid gravity

W: Support gravity.

The list is as follows:

force Lever Torque direction Left side box WB1 LB1 WB1×LB1 Counterclockwise Left side working fluid WW1 LW1 WW1×LW1 Counterclockwise Left spring SF1 LS1 SF1×LS1 Clockwise Left lift LF1 L1 LF1×L1 Clockwise

The overall torque (Torque, clockwise is positive, counterclockwise is negative), T = (-WB1×LB1-WW1×LW1+SF1×LS1+LF1×L1)+(WB2×LB2+WW2×LW2-SF2×LS2-LF2×L2).

If T>0, the tendency is clockwise rotation; if T<0, the tendency is counterclockwise rotation.

The fixed values of the aforementioned parameters are WB1 and WB2, and the other parameters WW1, WW2, SF1, SF2, LF1 and LF2 are variable values. In the figure shown, when the working fluid WF tilts to the right, the weight of the working fluid WF on the right side will be WW2>WW1, but the relative lifting force of the spring SF2>SF1, tending to rotate counterclockwise. As long as the specifications and dimensions of the spring are appropriately selected, the long box 10 can be relatively easily rotated counterclockwise, thereby reducing the force required to be applied by LF2. Although the weight of the overall working fluid WF is biased to the right, it is relatively easy to meet the requirement of counterclockwise rotation, and then the working fluid WF is poured into the first accommodation chamber 13. During the flow, the working fluid WF will pass through the water channel 15, drive the impeller 21 to rotate, and generate electrical output through the generator 22.

Please refer to FIG. 3 . In one embodiment, the seesaw-like hydroelectric power generation device of the present application further includes a power transmission system 60. The power generated by the generator 21 of the aforementioned hydroelectric generator set 20 is electrically connected to the power transmission system 60 via a cable. The current is divided into two paths after passing through the rectifier 61. One of the paths is sequentially passed through the inverter 62, and then the voltage is boosted by the boost device 63, and then the power is merged into the power grid 64. A storage device 65 can be added between the rectifier 61 and the inverter 62 to achieve the functions of energy storage and voltage stabilization. The other path is first passed through the storage box 66, and then passed through the speed regulator 67, and then connected to the aforementioned lifting mechanism 50. The speed of the lifting mechanism 50 is adjusted by the speed regulator 67, that is, the flip angle and frequency of the long box 10 can be controlled, and then the water flow and the amount of power generation can be controlled.

Please refer to FIG. 4 and FIG. 5. During operation, when the left side of the long box 10 is at the highest position, the right side of the long box 10 is at the lowest position, and the working fluid WF will accumulate in the second accommodation chamber 14. The second pulley block 55 will exert an upward force LF2 (see FIG. 2). In fact, only the output force LF22 is required, where LF22 = 1/4 LF2. Because the spring force SF2> SF1, LF2 becomes relatively small, and the actual force LF22 is even smaller.

When the long box 10 is in a horizontal state, the working fluid WF in the first accommodating chamber 13 and the second accommodating chamber 14 are equal, the spring force SF2=SF1, and the relatively small force LF22 can make the long box 10 continue to rotate counterclockwise. When the working fluid WF continues to flow into the first accommodating chamber 13, the weight of the working fluid WF in the first accommodating chamber 13 will be under the action of a very small LF22 force, which can continue to allow the long box 10 to rotate to another inclined direction (as shown in Figure 5). At this time, the left side of the long box 10 is at the lowest position, and the right side of the long box 10 is at the highest position. At this time, the force is applied to the left side, and the lift LF1 (see Figure 2) can make the long box 10 rotate clockwise to another horizontal state; then, it reaches the initial state, and this cycle continues to flip and swing.

Please refer to FIG. 6 . The seesaw-like hydroelectric power generation device of the present application can be used in addition to the above-mentioned embodiments. It can also be used in the form of the present embodiment, in which the first pulley group 51 and the second pulley group 55 of the lifting mechanism 50 are arranged above the water tank 8 and fixed. The elongated box 10, the hydro-generator group 20 and the fulcrum structure 30 are arranged in the water tank 8, and water 81 is injected into the water tank 8. When the elongated box 10 is in the form of FIG. 6 , the working fluid WF in the second chamber 14 is the largest, the weight is the largest, and the volume immersed in the water 81 is the largest. Therefore, the upward buoyancy SF2 generated by the box on the side of the second chamber 14 is greater than the upward buoyancy SF1 generated by the box on the side of the first chamber 13. That is, the springs 41 and 42 of the above-mentioned embodiments are replaced by water buoyancy (i.e., the lifting mechanism). The actuation mode and principle are the same as those of the above-mentioned embodiments, so they will not be repeated. In addition, the above-mentioned water tank 8 can also be in a lake or in the sea, and it also has the same effect.

Please refer to Figure 7. The lifting mechanism 50A of this embodiment mainly includes an electric motor 56 and a steel cable 57. The electric motor 56 is arranged above the long box 10 and the water tank 8 and is fixed. The middle section of the steel cable 57 is wound around the wheel of the electric motor 56, and the two ends of the steel cable 57 are respectively connected to the first chamber pulling point 16 and the second chamber pulling point 17, so that the long box 10 is driven by the forward and reverse rotation of the electric motor 56 to produce a continuous flipping and swinging cycle.

In summary, the seesaw-like hydroelectric power generation device of the present application can indeed achieve the intended purpose of use and solve the deficiencies of the prior art. Moreover, due to its great novelty and progressiveness, it fully meets the requirements for an invention patent application, and therefore an application is filed in accordance with the Patent Law.
