Description

Technical Field

[0001] This application relates to the field of power generation devices, and particularly to a friction and electromagnetic composite power generation mechanism and its wind power generation device. Background Art

[0002] In the face of the increasingly severe energy crisis, the exploration of renewable energy has become one of the important challenges for sustainable energy development. Traditional energy sources such as high-quality low-entropy energy like oil, coal, and natural gas can no longer meet the energy usage needs of humans. Therefore, there is an urgent need for some alternative energy sources such as green energy like wind energy in nature.

[0003] Currently, for the collection of wind energy on the ocean and on land, an electromagnetic and triboelectric composite power generation device is used. This device includes a cylindrical outer shell and an internal rotor. Friction materials are provided on the rotor, and electrodes are provided on the inner wall of the cylindrical outer shell. The wind energy is converted into the kinetic energy of the rotor rotation through the rotation of the wind blades. The rotation of the rotor drives the friction between the friction plate and the electrode while cutting the magnetic induction line to achieve composite power generation. However, when the rotor of this power generation device rotates continuously at a high speed, the temperature of the friction plate is likely to increase, thereby increasing the consumption speed of the friction plate, resulting in fast friction wear and reduced service life. Moreover, most of the kinetic energy of the rotor is converted into heat generated by friction, resulting in low power generation efficiency.

[0004] In response to the problem of low power generation efficiency caused by the existing power generation device, no effective solution has been proposed yet. Summary of the Invention

A plurality of magnets are provided on the outer circumferential surface of the cylindrical outer ring, and the magnets are aligned with the convex platforms one by one. A plurality of metal coils are provided on the side of the convex platform close to the magnet.

[0007] Furthermore, the ratio of the number of electrodes to the number of friction rings is 11:1 or 11:2 or 11:3 or 11:4 or 11:5.

[0008] Furthermore, three grooves are provided on the inner wall of the cylindrical shell, and three support shafts are correspondingly provided on the outer side of the cylindrical outer ring for sliding cooperation with the three grooves.

[0009] Furthermore, a bearing is sleeved on the support shaft, and the bearing is located in the gap or groove between two adjacent bosses, and the bearing is limited to move vertically in the gap or groove.

[0010] Furthermore, the metal electrode column is a copper electrode column, and a number of copper electrodes are equidistantly arranged on the copper electrode column.

[0011] Furthermore, the metal coil is a copper coil, and a number of copper coils are arranged along the axial direction on the side of the boss close to the magnet.

[0012] Furthermore, the drive source is a mechanical transmission device, and the mechanical transmission device includes a wind blade, a crank, a connecting rod and a rotating seat.

[0013] The present invention also provides a wind energy power generation device, which includes a friction and electromagnetic compound power generation mechanism and an energy storage device.

[0016] Compared with the related art, the present invention has the following beneficial effects:

[0017] 1. The friction ring is lined with a friction material. The friction between the friction material and the electrode can effectively generate electricity. When generating electricity by friction, the sliding device linearly reciprocates on the fixed shaft to achieve friction power generation between multiple groups of electrodes and the friction material. During this process, since a single group of electrodes and the friction material will separate after the friction ends and effective heat dissipation occurs, the electrodes have good heat dissipation effects, avoiding the reduction of the electric energy conversion efficiency caused by heat accumulation. At the same time, it is difficult for heat to accumulate during friction, keeping the friction material and the electrodes within the normal operating temperature range, reducing material loss. Thus, when consuming the same amount of wind energy, the service life and power generation efficiency are effectively improved.

[0018] 2. During the movement of the sliding device, the support shaft and the groove are in a limiting state. At this time, the sliding device connected to the support shaft also maintains a stable posture, thus achieving the effect of a stable posture.

[0019] 3. The movement between the support shaft and the groove can be smoother. And when the bearing is located in the groove, the outer edge of the groove blocks the bearing, which can further prevent the sliding device from tilting during sliding, further improving the operation stability.

[0020] 4. A transparent top cover is installed on the top of the cylindrical shell to wrap and seal the energy storage device and the solar panel, which can achieve the effects of rain protection and pollution prevention for the solar panel and the energy storage device.

[0021] 5. The cylindrical outer ring, the friction ring group and the central ring can be set as a detachable structure, that is, modular loading and unloading. When performing equipment maintenance, if one of the friction rings is damaged, the damaged friction ring can be directly replaced. Compared with the prior art, it is not necessary to replace the whole friction material, effectively saving the maintenance cost and improving the economic benefit.

[0031] The present invention is a wind energy power generation device, and its principle is: realizing composite power generation through the combination of triboelectric power generation and electromagnetic power generation, that is, the wind blades 3 receive wind energy and rotate, and the rotating wind blades 3 drive the sliding device 8 to slide in a straight line direction through a mechanical structure. During the process of the sliding device 8 sliding in a straight line direction, triboelectric power generation and cutting magnetic induction lines for power generation are simultaneously realized, and finally the wind energy is converted into electrical energy.

[0032] Please refer to Figures 1 to 2 , this embodiment provides a triboelectric and electromagnetic composite power generation mechanism, including a cylindrical shell 4, a sliding device 8 and a driving source.

[0033] Please refer to Figure 2 , Figure 4 and Figure 5, wherein, a fixed shaft 7 is fixed inside the cylindrical shell 4. It can be that the fixed shaft 7 is fixed in the axial direction of the inner part of the cylindrical shell 4, or it can be that the fixed shaft 7 is fixed parallel to the axial direction inside the cylindrical shell 4. Preferably, the fixed shaft 7 is fixed in the axial direction of the inner part of the cylindrical shell 4. The fixed shaft 7 is a smooth circular shaft. Lubricating oil can be applied to the outer wall of the fixed shaft 7 to reduce friction and frictional loss, thereby improving the service life and reducing the temperature. A number of convex platforms 15 are provided on the inner wall. The number of convex platforms 15 all extend along the axial direction of the cylindrical shell 4. Preferably, a number of convex platforms 15 are equally spaced on the semi-circular circumference of the inner wall of the cylindrical shell 4. The shape of the convex platform 15 is a cuboid, and the outer side of the convex platform 15 is flush with the axis.

[0034] In addition, a number of metal electrode columns 9 are fixed inside the cylindrical shell 4, and the fixed shaft 7 and the number of metal electrode columns 9 all extend along the axial direction of the cylindrical shell 4. In this embodiment, a number of metal electrode columns 9 can be evenly distributed in a circumferential direction. The advantage of uniform distribution is that the structure is symmetric and coordinated, and it will not skew during use and is more stable. In some other embodiments, a number of metal electrode columns 9 can also be unevenly distributed in a circumferential direction, but it is easy to skew during use, resulting in increased friction, rising temperature, and reduced service life of the device. A number of electrodes are provided on the metal electrode column 9. The sizes of the electrodes are the same and are stacked layer by layer on the metal electrode column 9. The shape of the metal electrode column 9 is an oblong rod.

[0035] Please refer to Figure 2 and Figure 3 , a sliding device 8 is arranged inside the cylindrical shell 4. The sliding device 8 includes a coaxial cylindrical outer ring, a number of friction ring groups fixedly arranged inside the cylindrical outer ring, and a central ring. The central ring is slidably sleeved on the fixed shaft 7. The friction ring group is formed by laminating a number of sections of friction rings with coincident axes. A number of metal electrode columns 9 penetrate through the number of friction ring groups one by one. Friction materials 11 are attached to the inner walls of the friction rings. The friction materials 11 are used for non-contact friction electrification with the electrodes. The friction rings and the electrodes have the same height, and the ratio range of the number of electrodes to the number of friction rings is from 11 to 1 to 11 to 5. This non-contact friction electrification is a mature technology in the prior art. The friction layer is preferably made of a polymer material with good electronegativity, such as fluorine-containing materials, fluorinated isopropylene (FEP), polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), etc. In terms of material selection, the required materials are simple, and any polymer insulating material with electronegativity can be used as the friction layer to generate an output signal.

[0036] Among them, a number of magnets 12 are arranged on the outer circumference of the outer ring of the cylinder, and the magnets 12 are aligned with the bosses 15 one by one. A number of metal coils 17 are arranged on the side of the boss 15 close to the magnet 12. In this way, when the outer ring of the cylinder slides, the metal coil 17 will cut the magnetic induction lines of the magnet 12 to generate electricity by induction. Specifically, 8 columns of magnets are evenly distributed within the 180-degree range of the outer ring of the cylinder. Each column of magnets includes an N pole and an S pole. 13 metal coils 17 are installed on each boss along the axial direction.

[0037] Currently, electromagnetic and triboelectric hybrid power generation devices are used for wind energy collection on the ocean and on land. The device includes a cylindrical outer shell and an internal rotor. Friction materials are arranged on the rotor, and electrodes are arranged on the inner wall of the cylindrical outer shell. The wind energy is converted into the kinetic energy of the rotor rotation through the rotation of the wind blades. The rotation of the rotor drives the friction between the friction plate and the electrode and cuts the magnetic induction lines at the same time to achieve hybrid power generation. However, when the rotor of this power generation device rotates at a high speed, the temperature of the friction plate is likely to rise, thereby increasing the consumption speed of the friction plate, resulting in fast friction loss and reduced service life. Moreover, most of the kinetic energy of the rotor is converted into heat generated by friction, resulting in low power generation efficiency.

[0038] The key point of the present invention is that it has higher power generation efficiency and longer service life compared with the prior art. A friction material 11 is attached to the inner side of the friction ring. The friction between the friction material 11 and the electrode can effectively generate electricity. When generating electricity by friction, the outer ring of the cylinder slides linearly back and forth on the fixed shaft 7 to achieve the friction power generation between multiple groups of electrodes and the friction material 11. During this process, since the single-group electrode and the friction material 11 will separate after the friction ends during friction and effective heat dissipation is carried out, the electrode has a good heat dissipation effect, avoiding the reduction of the electric energy conversion efficiency caused by heat accumulation. At the same time, it is difficult for heat to accumulate during friction, so that the friction material 11 and the electrode are within the normal working temperature range, reducing material loss, thereby effectively improving the service life and power generation efficiency under the condition of consuming the same amount of wind energy.

[0039] The reduction of the electric energy conversion efficiency caused by the accumulated heat can be understood as follows: when the metal temperature rises, the thermal vibration of the internal atoms intensifies, and the probability of collision between free electrons during the directional movement and the atoms increases, resulting in an increase in resistivity and a decrease in conductivity. As a result, more energy will be converted into heat dissipation, leading to a reduction in the electric energy conversion efficiency.

[0040] In special application scenarios, when the device needs to be partially modified to increase the power generation, the number of metal electrode columns 9 and the friction ring group can be increased. Compared with the prior art, this modification will not increase the burden on the device, that is, the friction material still has good heat dissipation.

[0041] In some other embodiments, the cylindrical outer ring, the friction ring group and the central ring can be configured as a detachable structure, i.e., modular loading and unloading. When performing equipment maintenance, if one of the friction rings is damaged, the damaged friction ring can be directly replaced. Compared with the prior art, there is no need to replace the whole friction material, effectively saving the maintenance cost and improving the economic benefits.

[0042] Since the friction ring has the best power generation efficiency when in non-contact frictional electrification with the metal electrode column 9, in order to prevent the friction ring from contacting the metal electrode column 9 during movement, the present invention also designs a limiting structure, which is specifically as follows: three grooves 16 are provided on the inner wall of the cylindrical shell 4, and three support shafts 13 are correspondingly provided on the outer side of the cylindrical outer ring for sliding cooperation with the three grooves 16. The advantage of this is that during the movement of the cylindrical outer ring, the support shafts 13 and the grooves 16 are in a limiting state, and at this time, the cylindrical outer ring connected to the support shafts 13 also maintains a stable posture, thus achieving the effect of a stable posture.

[0043] And in order to further reduce the friction force and energy loss, please refer to Figure 5 and Figure 6 , furthermore, a bearing 18 is sleeved on the support shaft 13, and the bearing 18 is located in the gap between two adjacent bosses 15 or in the groove 16, and the bearing 18 is limited to move vertically in the gap or the groove 16. After adding the bearing 18, the movement between the support shaft 13 and the groove 16 can be smoother, and when the bearing 18 is located in the groove 16, the outer edge of the groove 16 blocks the bearing 18, which can further prevent the cylindrical outer ring from skewing during sliding and further improve the running stability.

[0044] In addition, the friction area can also change with the number of metal electrode columns 9 and the number of friction ring groups, so as to realize the improvement and control of the friction area.

[0045] In addition, the ratio of the electrodes of the metal electrode columns 9 to the number of friction ring layers (quantity) also affects the power generation efficiency. When the friction ring and the electrode have the same height, and the ratio range of the number of electrodes to the number of friction rings is from 11:1 to 11:5, the friction electromagnetic composite power generation has good power generation efficiency. And in further experiments, it is concluded that when the ratio of the number of electrodes to the number of friction rings is any one of 11:1 or 11:2 or 11:3 or 11:4 or 11:5, it has better power generation efficiency.

[0046] Please refer to Figures 1 to 2, a driving source is used to provide the kinetic energy required for the sliding of the cylindrical outer ring. The driving source is a mechanical transmission device 10, and the mechanical transmission device 10 includes a wind blade 3, a crank, a connecting rod, and a rotating seat. The rotating seat is installed at the outer center of the cylindrical outer ring. The crank is rotatably installed on the inner wall of the cylindrical shell 4 and the crank pin penetrates through the cylindrical shell 4. The wind blade 3 is installed on the crank pin. The crank is connected to the rotating seat through a connecting rod. The rotating seat does not obstruct the boss 15, the support shaft 13, and the magnet 12. During use, the wind blade 3 rotates under the influence of wind force. The rotation of the wind blade 3 drives the crank to rotate. The rotation of the crank drives the connecting rod to rotate. The rotation of the connecting rod drives the rotating seat to move linearly back and forth. The linear reciprocating movement of the rotating seat drives the cylindrical outer ring to move linearly back and forth, thereby realizing friction and electromagnetic compound power generation.

[0047] In order to further improve the power generation effect, the metal electrode column 9 can be used as a copper electrode column, and a number of copper electrodes 14 are equidistantly arranged on the copper electrode column. At the same time, the metal coil 17 is a copper coil, and a number of copper coils are arranged along the axial direction on the side of the boss 15 close to the magnet 12. The above-mentioned copper can also be replaced by aluminum. The sizes of the metal coil 17 and the magnet 12 can be appropriately adjusted according to the device size.

[0048] Please refer to Figure 1 , the present invention also provides a wind energy power generation device, including a friction and electromagnetic compound power generation mechanism and an energy storage device 2. The friction and electromagnetic compound power generation mechanism is the above-mentioned friction and electromagnetic compound power generation mechanism. The energy storage device 2 is hermetically installed at the top opening of the cylindrical shell 4 and is used to store the electric energy generated by the wind energy power generation device. The energy storage device 2 can be a battery or other existing energy storage items.

[0049] Since there is also sunlight in the actual application scenario of the present invention, in order to make full use of resources, a solar panel 6 can be provided on the top of the energy storage device 2 to convert solar energy into electric energy and store it in the energy storage device 2. A transparent top cover 1 is installed on the top of the cylindrical shell 4 to wrap and seal the energy storage device 2 and the solar panel 6, which can achieve the effects of rain protection and pollution prevention for the solar panel 6 and the energy storage device 2.

[0050] For the convenience of installation, a chassis 5 is installed at the bottom of the cylindrical shell 4. The chassis 5 is used to fix the cylindrical shell 4 on a marine float or the ground, so as to adapt to different application scenarios.

[0051] The present invention also has an application method, that is, directly connecting the energy storage device 2 of the present invention to various sensors on the ocean or on land to realize the power supply for these sensors.
