Description

Technical Field

[0001] The present invention relates to the technical field of mechanical power generation, and in particular to a power-assisted power generation device. Background Art

[0002] There are many hydroelectric power generation equipments at present, but most of them use the water drop formed by damming to impact the power wheel, and then convert the gravitational potential energy of the water flow into electrical energy through the mechanical energy of the impeller. However, damming not only has huge investment costs, but also is constrained by geographical conditions. At the same time, because the flow rate of many rivers is too slow, the efficiency of conventional hydroelectric power generation devices is low, so the natural flow of rivers is not fully utilized.

[0003] In the prior art, there are some devices that use natural rivers to generate electricity, such as the invention patent with application number 201110322214.7. The gravity balls and gravity rods set inside and outside the spokes can move up and down according to the rotation of the spokes, and the gravity potential energy of the weights can be used to further increase the rotation speed of the spokes, thereby driving the power wheel to rotate faster. However, the assistance and resistance generated by the gravity balls and gravity rods are equivalent, so the effect of accelerating the rotation of the power wheel is not obvious. At the same time, during the rotation of the power wheel, the centrifugal force affects the movement state of the gravity balls and gravity rods, which will have a negative impact on the rotation speed of the power wheel. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a power-assisted power generation device, which adopts arc-shaped spokes and push blocks to make the counterweight block approach the wheel hub in advance during the rising process, which is beneficial to reduce the torque, reduce the load work, and increase the speed of the power wheel. At the same time, the push rod connects the counterweight block in the corresponding spoke, which can make the counterweight block move away from the wheel hub in advance during the descent process, increase the torque, increase the power-assisted work, and increase the speed of the power wheel, and can also reduce the influence of centrifugal force on the movement of the counterweight block during the rotation of the power wheel, and the acceleration effect of the power wheel is obvious.

[0032] The arc-shaped spoke 10 is provided with an arc-shaped through groove 14, and the counterweight block 12 is provided with a positioning shaft 16, and the positioning shaft 16 passes through the arc-shaped through groove 14 and cooperates with the arc track 501; the feeding device 6 includes a worm, and the worm is fixedly mounted on the push block 5, and the worm is connected to a turbine, and the turbine is fixedly mounted on the mounting platform 1, and the turbine is connected to a motor; the push rod 13 includes an arc-shaped rod 1301, and the arc-shaped rod 1301 is fixedly mounted on the counterweight block 12, and the shape of the arc-shaped rod 1301 is the same as that of the arc-shaped spoke 10, and a connecting rod 1302 is hinged between the arc-shaped rods 1301 in the corresponding arc-shaped spokes 10; the thickness of the arc-shaped rod 1301 is less than 1 / 5 of the thickness of the counterweight block 12, and the thickness of the connecting rod 1302 is not greater than the thickness of the arc-shaped rod 1301, which can avoid the adjacent push rods 13 in the wheel Interference occurs in the hub 7; an arc-shaped through groove 14 is provided on the arc-shaped spoke 10, and a positioning shaft 16 is provided on the counterweight 12, and the positioning shaft 16 cooperates with the arc-shaped through groove 14 to limit the counterweight 12; slide rails 15 are provided on both sides of the arc-shaped through groove 14 in the slideway 11, and fixedly installed shafts 17 are provided at both ends of the counterweight 12, and wheels 18 are provided at both ends of the shaft 17, and the wheels 18 cooperate with the slide rails 15, and the movement of the counterweight 12 is achieved by the wheels 18, and rolling replaces sliding, which is beneficial to reducing friction resistance; the bending direction of the arc-shaped spoke 10 is the same as the rotation direction of the power wheel 4; there are 10 spokes, and there are 5 fixed positions of the counterweight 12 and the arc rod 1301, and the arc rod 1301 at the same fixed position is hinged by the connecting rod 1302 to form the push rod 13.

[0033] When the present invention is working, when the push block 5 is not matched with the positioning shaft 16, a plurality of evenly distributed arc blades are installed on the outer ring 8, and the power wheel 4 is provided with power by the impact of water flow on the arc blades, and the rotation direction of the power wheel 4 is made the same as the bending direction of the arc spokes 10. During the rotation of the power wheel 4, the arc spokes 10 perform circular motion. When the arc spokes 10 rotate from the lowest point to the highest point, the corresponding arc spokes 10 rotate from the highest point to the lowest point. The counterweight block 12 on the arc spoke 10 is rotated under its own weight. Under the action of the sliding rail 15, it moves toward the direction close to the wheel hub 7. Because the sliding rail 11 is arc-shaped, after the arc-shaped spoke 10 rotates a certain angle (less than 90°), the counterweight 12 on the arc-shaped spoke 10 starts to move toward the direction close to the wheel hub 7. Compared with the straight spoke, the counterweight 12 on the arc-shaped spoke 10 moves toward the wheel hub 7 in advance, so that the resistance work generated by the counterweight 12 is reduced. At the same time, the counterweight 12 on the corresponding arc-shaped spoke 10 is connected with the counterweight 12 on the arc-shaped spoke 10 through a push rod 13. When the counterweight 12 on the arc-shaped spoke 10 moves close to the wheel hub 7, the counterweight 12 on the corresponding arc-shaped spoke 10 moves away from the wheel hub 7 under the action of the push rod 13. Compared with the straight spoke, the push rod 13 not only realizes that the counterweight 12 on the corresponding arc-shaped spoke 10 moves away from the wheel hub 7 in advance, thereby increasing the power-assisted work, but also converts part of the resistance work into power-assisted work, thereby improving the energy utilization rate. At the same time, the counterweight 12 on the corresponding pair of arc-shaped spokes 10 is connected by the push rod 13 to offset the rotation of the power wheel 4. Partial centrifugal force makes the counterweight 12 move more flexibly in the slide 11; when the push block 5 cooperates with the positioning shaft 16, the counterweight 12 always moves in the direction close to the wheel hub 7 during the rising process. After the positioning shaft 16 on the counterweight 12 contacts the arc track 501, the resistance torque generated by the counterweight 12 begins to decrease, and the assist torque generated by the counterweight 12 in the corresponding arc spoke 10 begins to increase, which is beneficial to reduce the resistance work on the power wheel 4, increase the assist work, and help increase the rotation speed of the power wheel 4.
