Description
Technical Field
The invention relates to a power generation device based on rolling motion, which can be arranged in rolling wave power generation equipment or a rolling wave-absorbing embankment and belongs to the field of new energy resources for power generation by utilizing ocean energy.
Background
In 1974, engineer Salter invented a roll-type wave energy conversion device, which was designed strictly, and had an asymmetric cross-sectional profile, a smaller front end (wave-facing surface), a larger rear end (wave-backing surface), and a circular arc-shaped underwater portion, and which was rolled around a rotating shaft under the action of waves and was able to intercept almost all short waves, and the primary conversion efficiency of the wave energy conversion device at short waves was close to 100%.
Although wave power generation research has been developed for decades, dozens of different power generation devices have been designed in order to improve power generation efficiency. However, the existing wave-activated generator still has the following disadvantages: the wave energy generator has the advantages of complex structure, excessive friction, high manufacturing cost, easy failure, short service life, high wave energy loss, and short effective working time caused by very easy stop of work when waves are small. Furthermore, some wave-breaking devices have a rolling motion during wave breaking, which is derived from wave energy, but is usually wasted. By installing the power generation device, the wave energy can be converted into electric energy for further utilization.
Based on the rolling device with extremely high wave energy and mechanical energy conversion efficiency, the invention designs and installs the power generation device with simple structure, low manufacturing cost, strong reliability, high energy efficiency ratio, long effective working time and good economic benefit in the rolling equipment, and effectively solves the problems of complex structure, high manufacturing cost, high failure rate, low energy conversion rate and short effective working time of the existing rolling wave power generation device.
Disclosure of Invention
Aiming at various defects in the prior art, the invention provides a rolling type power generation device which is simple in structure, low in manufacturing cost, high in reliability and high in energy efficiency ratio.
The technical scheme adopted by the invention is as follows: a power generation device based on rolling motion comprises a first rotating shaft, a large gear, a small gear, a second rotating shaft, a generator, bearings, a first one-way bearing, a second one-way bearing and rolling equipment, wherein the generator and a plurality of bearings are fixedly connected to the rolling equipment; the second rotating shaft is connected with the generator and the bearing, the second one-way bearing is fixedly nested on the second rotating shaft, the pinion is fixedly nested on the second one-way bearing and is positioned between the generator and the bearing, and the pinion is tightly meshed with the gearwheel; the first rotating shaft is the rotating center of the rolling equipment, the rolling equipment takes the first rotating shaft as the center and drives the first rotating shaft to do rolling motion together, and the first rotating shaft drives the first one-way bearing to rotate along with the first rotating shaft; when the speed of the first rotating shaft rotating along with the rolling equipment in the clockwise direction is higher than that of the big gear, the first one-way bearing drives the big gear to rotate in an accelerated manner, and when the speed of the first rotating shaft rotating along with the rolling equipment in the anticlockwise direction is lower than that of the big gear, the first one-way bearing does not drive the big gear to rotate any more, and the big gear only rotates in one direction under the driving of the first one-way bearing; in the process, the large gear drives the small gear meshed with the large gear to rotate, and when the counterclockwise rotating speed of the small gear is higher than that of the second rotating shaft, the second one-way bearing drives the second rotating shaft to rotate in an accelerated manner; when the clockwise rotation speed of the pinion is lower than that of the second rotating shaft, the second one-way bearing does not drive the second rotating shaft to rotate any more; the rotation of the pinion transfers the power to the second rotating shaft to drive the generator to work and generate electricity.
By adopting the technical scheme, the energy input of the device is based on the rolling motion of the rolling equipment, and the rolling motion of the rolling equipment is the main power source of the power generation device. The power generation device converts the mechanical energy of the rolling equipment in rolling into electric energy. In the mechanism, the first rotating shaft is fixedly connected with the rolling equipment, and the first rotating shaft can be driven to rotate together with the rolling equipment when the rolling equipment rolls. When the first rotating shaft rotates along with the rolling equipment, the large gear is driven to rotate along with the first one-way bearing, and then the large gear transmits the rotating speed to the second rotating shaft through the small gear, so that the generator is driven to work and generate abundant electric energy. The inertia moment of the gearwheel is larger, and the gearwheel is driven by the first one-way bearing to rotate only along one direction.
In order to ensure that the large gear continuously transmits the rotating speed to the second rotating shaft through the small gear when the rolling equipment rotates, and then the generator is driven to work, a first one-way bearing needs to be installed between the first rotating shaft and the large gear, and a second one-way bearing needs to be installed between the second rotating shaft and the small gear.
The effects of the first one-way bearing and the second one-way bearing are common and different, and the common points are as follows: no matter what kind of stormy waves are encountered by the rolling equipment, the rolling equipment does rolling motion with any frequency and amplitude, and the first one-way bearing and the second one-way bearing can convert the rolling equipment into continuous one-way rotation so that the generator can convert mechanical energy into electric energy. The difference is that:
1. the first one-way bearing has the following functions: when the speed of the first rotating shaft rotating along with the rolling equipment in the clockwise direction is higher than that of the big gear, the first one-way bearing drives the big gear to rotate in an accelerating mode, and when the speed of the first rotating shaft rotating along with the rolling equipment in the anticlockwise direction is lower than that of the big gear, the first one-way bearing does not drive the big gear to rotate any more.
2. The second one-way bearing has the following functions: when the speed of the pinion rotating in the anticlockwise direction is higher than that of the second rotating shaft, the second one-way bearing drives the second rotating shaft to rotate in an accelerated mode, and when the speed of the pinion rotating in the clockwise direction is lower than that of the second rotating shaft, the second one-way bearing does not drive the second rotating shaft to rotate any more.
The power of the power generation device mainly comes from the rolling of the rolling equipment, the power generation device can be arranged in fixed rolling equipment and can also be arranged in floating rolling equipment, and the two types of rolling equipment can roll along with the movement of waves on the water surface.
When the speed of the rotating shaft is lower than that of the big gear, the big gear can continuously keep forward rotation to convey energy to the generator because the big gear has larger rotational inertia and more stored energy and cannot be quickly consumed by the generator.
Conventionally, the power generation apparatus needs to be connected to an electric storage device or a user device through a voltage stabilizer.
The invention has the beneficial effects that:
1. the power generation device is based on rolling equipment, and the rolling equipment has great advantages in the aspect of converting wave energy into mechanical energy. It can intercept almost all short waves and the first order wave energy conversion efficiency at short waves can be close to 100%.
2. The power generation device can sense smaller waves, is high in sensitivity, achieves the effect of accelerating the rotating speed through the matching of the big gear and the small gear, then transmits the rotation to the power generator, and achieves continuous power generation.
3. The first one-way bearing and the second one-way bearing of the power generation device can realize that the mechanical energy of the rolling equipment can be continuously transmitted to the power generator through the big gear and the small gear. The reason is that no matter what kind of wind and wave is encountered by the rolling equipment and the rolling equipment does rolling motion with what kind of frequency and amplitude, the first one-way bearing and the second one-way bearing can convert the rolling equipment into continuous one-way rotation, so that the generator can convert mechanical energy into electric energy, the effective working time of the power generation device is greatly prolonged, the power generation amount is increased, and the economic benefit is improved.
4. The power generation device is simple in structure, can reduce the construction cost and realize large-area popularization and application on one hand, and is strong in reliability, low in maintenance rate and low in maintenance cost on the other hand, most importantly, the power generation device is long in effective working time, large in power generation amount and capable of realizing excellent economic benefits.

Detailed Description
The technical solution of the present invention is further explained with reference to the drawings and the embodiments.
Fig. 1, 2, and 3 show a structure of a roll type power generation apparatus. In the figure, the power generation device based on the rolling motion comprises a first rotating shaft 1, a large gear 3, a small gear 4, a second rotating shaft 5, a generator 6, a bearing 7, a first one-way bearing 2, a second one-way bearing 8 and rolling equipment 9, wherein the generator 6 and a plurality of bearings 7 are fixedly connected to the rolling equipment 9. The first rotating shaft 1 is fixedly connected with the rolling equipment 9 through two bearings 7, the first one-way bearing 2 is fixedly nested on the first rotating shaft 1, and the large gear 3 is fixedly nested on the first one-way bearing 2. The second rotating shaft 5 is connected with a generator 6 and a bearing 7, a second one-way bearing 8 is fixedly nested on the second rotating shaft 5, a pinion 4 is fixedly nested on the second one-way bearing 8 and is positioned between the generator 6 and the bearing 7, and the pinion 4 is tightly meshed with the gearwheel 3. The first rotating shaft 1 is a rotating center of the rolling equipment 9, the rolling equipment 9 takes the first rotating shaft 1 as a center and drives the first rotating shaft 1 to do rolling motion together, and the first rotating shaft 1 drives the first one-way bearing 2 to rotate along with the first one-way bearing. When the speed of the first rotating shaft 1 rotating clockwise along with the rolling equipment 9 is greater than the speed of the large gear 3, the first one-way bearing 2 drives the large gear 3 to rotate at an accelerated speed, and when the speed of the first rotating shaft 1 rotating counterclockwise along with the rolling equipment 9 is less than the speed of the large gear 3, the first one-way bearing 2 does not drive the large gear 3 to rotate any more, and the large gear 3 only rotates along one direction under the driving of the first one-way bearing 2. In the process, the gearwheel 3 drives the pinion 4 engaged with the gearwheel to rotate, and when the counterclockwise rotation speed of the pinion 4 is higher than that of the second rotating shaft 5, the second one-way bearing 8 drives the second rotating shaft 5 to rotate in an accelerated manner. When the clockwise rotation speed of the pinion 4 is lower than that of the second rotating shaft 5, the second one-way bearing 8 does not drive the second rotating shaft 5 to rotate any more; the rotation of the pinion 4 transmits power to the second rotating shaft 5 to drive the generator 6 to generate electricity.
By adopting the technical scheme, when the speed of the first rotating shaft 1 is lower than that of the large gear 3, the large gear 3 can continuously keep forward rotation to transmit energy to the generator 6 because the large gear 3 has larger rotational inertia and more stored energy and cannot be quickly consumed by the generator 6. The diameter ratio of the large gear 3 and the small gear 4 is very large, and the large gear 3 and the small gear 4 rotate in a matched mode to play a role in acceleration, so that the rotating speed meets the power generation requirement of the power generator 6.
When the speed of the first rotating shaft 1 rotating along with the rolling equipment in the clockwise direction is greater than that of the large gear 3, the first one-way bearing 2 drives the large gear 3 to rotate in an accelerating mode, and when the speed of the first rotating shaft 1 rotating along with the rolling equipment 9 in the anticlockwise direction is less than that of the large gear 3, the first one-way bearing 2 does not drive the large gear 3 to rotate any more. The first one-way bearing can only drive the gearwheel to rotate clockwise in one way 3.
When the speed of the pinion 4 rotating in the counterclockwise direction is greater than that of the second rotating shaft 5, the second one-way bearing 8 drives the second rotating shaft 5 to rotate at an increased speed, and when the speed of the pinion 4 rotating in the clockwise direction is less than that of the second rotating shaft 5, the second one-way bearing 8 does not drive the second rotating shaft 5 to rotate any more. The second one-way bearing can only drive the second rotating shaft to rotate anticlockwise and one-way.
The operation mode of the power generation device based on the rolling motion is as follows: the rolling motion of the rolling equipment 9 with the first rotating shaft 1 as the center drives the first rotating shaft 1 to rotate in a reciprocating way, the first rotating shaft 1 converts the reciprocating rotation into the clockwise unidirectional rotation of the large gear 3 through the first unidirectional bearing 2, enough rotating speed is obtained through the meshing with the small gear 4, the rotating direction is also transmitted into the counterclockwise unidirectional rotation of the small gear, then the clockwise unidirectional rotation is transmitted to the second rotating shaft 5 through the second unidirectional bearing 8 to drive the generator 6 to rotate and generate electricity, and the transmitted electricity is connected with the electric storage equipment or the user equipment through the voltage stabilizing device.
