A power generation device based on rolling motion

technical field

The invention relates to a power generation device based on rolling motion, which can be installed in a rolling wave power generation device or a rolling wave breaker, and belongs to the field of new energy using ocean energy to generate electricity.

Background technique

In 1974, engineer Salter invented a rolling wave energy conversion device. The design of the device is rigorous and the cross-sectional profile is asymmetrical. The underwater part is arc-shaped, and the device rolls around the rotation axis under the action of waves, and can intercept almost all short waves. The first-order conversion efficiency of this wave energy conversion device in short waves can be close to 100%.

Although wave power research has been developed for decades, dozens of different power generation device designs have emerged to improve power generation efficiency. However, the existing wave generator still has the following shortcomings: complex structure, excessive friction, high manufacturing cost, easy failure, low service life, large wave energy loss, and when the wave is small, it is easy to stop working and cause it to work effectively. shorter time. In addition, some wave-dissipating devices have a rolling motion during wave-dissipation, and the rolling energy is derived from wave energy, but is usually wasted. By installing the power generation device in the present invention, the wave energy can be converted into electric energy and then utilized.

It is precisely based on this kind of rolling device with extremely high wave energy and mechanical energy conversion efficiency that the present invention is designed and installed in the rolling device with simple structure, low cost, strong reliability, high energy efficiency ratio, long effective working time and economical. The high-efficiency power generating device effectively solves the problems of complex structure, high cost, high failure rate, low energy conversion rate and short effective working time of the existing rolling wave power generating device.

SUMMARY OF THE INVENTION

In view of many deficiencies in the prior art, the present invention provides a roll-type power generation device, which should be a power generation device with simple structure, low cost, high reliability and high energy efficiency ratio.

The technical scheme adopted in the present invention is: a power generation device based on rolling motion, which includes a first rotating shaft, a large gear, a small gear, a second rotating shaft, a generator and a bearing, and also includes a first one-way bearing, a second The one-way bearing and the rolling device, the generator and the plurality of bearings are fixedly connected to the rolling device, the first rotating shaft is fixedly connected to the rolling device through two bearings, and the first one-way bearing is fixedly nested in the first rotating shaft The large gear is fixedly nested on the first one-way bearing; the second rotating shaft is connected to the generator and the bearing, the second one-way bearing is fixedly nested on the second rotating shaft, and the pinion is fixedly nested on the second rotating shaft. On the one-way bearing and between the generator and the bearing, the pinion and the large gear are closely meshed together; the first rotating shaft is the rotation center of the rolling equipment, and the rolling equipment takes the first rotating shaft as the center and drives the first rotating shaft together When the rolling motion is performed, the first rotating shaft drives the first one-way bearing to rotate accordingly; when the clockwise rotation speed of the first rotating shaft with the rolling equipment is greater than the speed of the large gear, the first one-way bearing drives the large gear to accelerate the rotation. When the speed of the counterclockwise rotation of the first rotating shaft with the rolling device is lower than that of the large gear, the first one-way bearing no longer drives the large gear to rotate, and the large gear only rotates in one direction driven by the first one-way bearing; during the above process , the large gear drives the pinion that meshes with it to rotate. When the speed of the pinion rotating counterclockwise is greater than that of the second shaft, the second one-way bearing drives the second shaft to accelerate; when the speed of the pinion clockwise is less than the second When rotating the shaft, the second one-way bearing no longer drives the second rotating shaft to rotate; the rotation of the pinion transmits the power to the second rotating shaft to drive the generator to work and generate electricity.

With the above technical solution, 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 generating device. The power generation device converts the mechanical energy of the rolling equipment into electrical energy. In the above mechanism, the first rotating shaft is fixedly connected with the roll device, and when the roll device rolls, the first rotating shaft can be driven to rotate together with it. When the first shaft rotates with the rolling device, the first one-way bearing drives the large gear to rotate along with it, and the large gear transmits the rotational speed to the second shaft through the pinion, thereby driving the generator to work to generate sufficient electrical energy. The inertia moment of the large gear itself is relatively large, and the large gear only rotates in one direction driven by the first one-way bearing.

In order to ensure that when the rolling equipment rotates, the large gear continuously transmits the rotational speed to the second rotating shaft through the pinion, and then drives the generator to work, it is necessary to install a first one-way bearing between the first rotating shaft and the large gear, and the second rotating shaft A second one-way bearing is installed between the pinion and the pinion.

The functions of the first one-way bearing and the second one-way bearing have similarities and differences. The common point is that no matter what kind of wind and waves the rolling equipment encounters, and at what frequency and amplitude, the first one-way bearing, The second one-way bearing can convert it into continuous one-way rotation, so that the generator can convert mechanical energy into electrical energy. The differences are:

1. The function of the first one-way bearing is: when the speed of the first rotating shaft rotating clockwise with the rolling device is greater than the speed of the large gear, the first one-way bearing drives the large gear to accelerate the rotation, and when the first rotating shaft rotates with the horizontal When the counterclockwise rotation speed of the shaking device is lower than that of the large gear, the first one-way bearing no longer drives the large gear to rotate.

2. The function of the second one-way bearing is: when the speed of the pinion rotating in the counterclockwise direction is greater than that of the second rotating shaft, the second one-way bearing drives the second rotating shaft to accelerate the rotation; When there are two rotating shafts, the second one-way bearing no longer drives the second rotating shaft to rotate.

The power of the power generation device mainly comes from the rolling of the rolling equipment, which can be installed in the fixed rolling equipment or in the floating rolling equipment. Both types of rolling equipment can be installed on the water surface. It rolls with the movement of the waves.

When the speed of the rotating shaft is less than the speed of the large gear, the reason why the large gear can continue to rotate in the forward direction to transmit energy to the generator is that the large gear has a large moment of inertia and stores more energy, which will not be quickly affected by the generator. Use up.

Conventionally, the power generation device needs to be connected to a power storage device or user equipment through a voltage stabilizer.

The beneficial effects of the present invention are:

1. The power generation device is based on rolling equipment, which has huge advantages in 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 perceive small waves and has high sensitivity. The effect of speed acceleration is achieved through the cooperation of large and small gears, and then the rotation is transmitted to the generator to achieve continuous power generation.

3. The first one-way bearing and the second one-way bearing mechanism of the power generating device can continuously transmit the mechanical energy of the rolling equipment to the generator through the large and small gears. This is because, no matter what kind of wind and waves the rolling equipment encounters, and what frequency and amplitude the rolling motion is, the first one-way bearing and the second one-way bearing can convert it into continuous one-way rotation, so as to facilitate power generation The machine converts mechanical energy into electrical energy, greatly extending the effective working time of the power generation device, increasing the power generation and improving its economic benefits.

4. The power generation device has a simple structure. On the one hand, it can reduce the construction cost and realize large-scale popularization and application. On the other hand, it has strong reliability, low maintenance rate and low maintenance cost. The most important thing is that it has a long effective working time and can generate electricity. Large quantity can achieve excellent economic benefits.

Detailed ways

The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Figures 1, 2 and 3 show the structure diagram of a rolling type power generating device. In the figure, the power generation device based on rolling motion includes a first shaft 1, a large gear 3, a pinion 4, a second shaft 5, a generator 6, a bearing 7, a first one-way bearing 2, and a second one-way bearing 8 and the rolling device 9 , the generator 6 and the plurality of bearings 7 are fixedly connected to the rolling device 9 . The first rotating shaft 1 is fixedly connected to the rolling device 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 to the generator 6 and the bearing 7, the second one-way bearing 8 is fixedly nested on the second rotating shaft 5, and the pinion 4 is fixedly nested on the second one-way bearing 8, and is located between the generator 6 and the second one-way bearing 8. Between the bearings 7, the pinion gear 4 and the large gear 3 are tightly meshed together. The first rotating shaft 1 is the rotation center of the rolling device 9. The rolling device 9 takes the first rotating shaft 1 as the center and drives the first rotating shaft 1 to perform a rolling motion together, and the first rotating shaft 1 drives the first one-way bearing 2 to rotate accordingly. . When the speed of the first rotating shaft 1 rotating clockwise with the rolling device 9 is greater than the speed of the large gear 3, the first one-way bearing 2 drives the large gear 3 to accelerate the rotation. When the first rotating shaft 1 rotates counterclockwise with the rolling device 9 When the speed is lower than that of the large gear 3, the first one-way bearing 2 no longer drives the large gear 3 to rotate, and the large gear 3 only rotates in one direction driven by the first one-way bearing 2. During the above process, the large gear 3 drives the pinion 4 meshed with it to rotate. When the speed of the pinion 4 rotating in the counterclockwise direction is greater than the second rotating shaft 5, the second one-way bearing 8 drives the second rotating shaft 5 to accelerate the rotation. When the speed of the clockwise rotation of the pinion 4 is lower than that of the second shaft 5, the second one-way bearing 8 no longer drives the second shaft 5 to rotate; the rotation of the pinion 4 transmits the power to the second shaft 5 to drive the generator 6 work to generate electricity.

Using the above technical solution, when the speed of the first rotating shaft 1 is lower than the speed of the large gear 3, the reason why the large gear 3 can continue to maintain the positive rotation to transmit energy to the generator 6 is that the rotational inertia of the large gear 3 is large, and its The stored energy is also more and will not be quickly consumed by the generator 6 . The diameter ratio of the large gear 3 and the pinion 4 is very large, and the coordinated rotation of the large gear 3 and the pinion 4 plays a role in acceleration, so that the rotational speed meets the power generation requirement of the generator 6 .

When the speed of the first rotating shaft 1 rotating clockwise with the rolling device is greater than the speed of the large gear 3, the first one-way bearing 2 drives the large gear 3 to accelerate the rotation. When the first rotating shaft 1 rotates counterclockwise with the rolling device 9 When the speed is lower than that of the large gear 3, the first one-way bearing 2 no longer drives the large gear 3 to rotate. The first one-way bearing can only drive the large gear to rotate clockwise in one direction 3 .

When the rotation speed of the pinion 4 in the counterclockwise direction is greater than that of the second shaft 5, the second one-way bearing 8 drives the second shaft 5 to accelerate the rotation. The one-way bearing 8 no longer drives the second rotating shaft 5 to rotate. The second one-way bearing can only drive the second shaft to rotate counterclockwise in one direction.

The operation mode of the power generation device based on rolling motion: the rolling motion of the rolling device 9 centered on the first rotating shaft 1 drives the first rotating shaft 1 to reciprocate, and the first rotating shaft 1 reciprocates through the first one-way bearing 2 . It is converted into the clockwise one-way rotation of the large gear 3, and after meshing with the pinion 4, a sufficient rotation speed is obtained, and the rotation direction is also transmitted to the counterclockwise one-way rotation of the pinion, and then passes through the second one-way bearing 8 It is transmitted to the second rotating shaft 5 to drive the generator 6 to rotate and generate electricity, and the generated electricity is connected to the power storage device or user equipment through the voltage stabilizer.
