Description

Technical Field

[0001] This invention relates to the field of hydropower generation equipment technology, and more specifically, to a water energy capture mechanism and a hydropower generation device. Background Technology

[0002] In hydrological scientific research, buoys are used as platforms for scientific research equipment. To ensure the normal operation of various scientific research equipment on the buoys, batteries need to be installed on the buoys to power the equipment. In addition, photovoltaic panels are usually installed on the buoys to extend the battery's range.

[0003] Existing buoys are typically connected to an underwater anchoring system via mooring lines, restricting their drift within a designated water area. Considering the continuous or periodic underwater currents in the mooring area, theoretically, installing a hydroelectric generator on the bottom of the buoy or on the mooring line could effectively supplement or replace traditional power sources while avoiding occupying the equipment layout space above the buoy. However, the speed of water currents varies frequently in natural environments. Traditional hydroelectric generators can only operate normally and generate electricity when the water current is relatively fast. In low-speed water currents, they may stop or experience a sharp drop in efficiency, resulting in low efficiency in capturing water current energy and limiting power generation efficiency. Summary of the Invention

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a water energy capture mechanism and a hydropower generation device, which aims to improve water energy capture capacity and power generation efficiency.

[0005] A first aspect of the present invention is to provide a water capture mechanism, comprising: A wave energy capture device includes a swinging part and a rotating part that are movably connected to each other. The swinging part can drive the rotating part to rotate by swinging up and down. The rotating part is coaxially connected to a first rotating shaft. A water flow energy capture device includes several movable couplings and a coaxially arranged active rotating component, a first driven rotating component, and a second driven rotating component. The active rotating component, the first driven rotating component, and the second driven rotating component are arranged sequentially back and forth along the axial direction. The center of the first driven rotating component is fixedly connected to a second rotating shaft, and the second driven rotating component is loosely fitted onto the second rotating shaft. Several movable couplings are disposed on the active rotating component, and the ends of the movable couplings away from the active rotating component extend sequentially through the space where the first driven rotating component and the second driven rotating component are located. Furthermore, the several movable couplings are spaced apart along the outer periphery of the first driven rotating component. When the active rotating component rotates, it can drive the movable couplings, so that the movable couplings couple to and rotate the first driven rotating component or the second driven rotating component. The third rotating shaft is connected to the first rotating shaft via a first transmission assembly and to the second rotating shaft via a second transmission assembly, wherein the first transmission assembly and the second transmission assembly transmit power to the third rotating shaft in the same direction.

[0006] In this invention, by fixing the first driven rotating component to the second rotating shaft and loosely fitting the second driven rotating component onto the second rotating shaft, it is possible to achieve a situation where one of the first and second driven rotating components rotates while the other remains stationary. It can be understood that when the driving rotating component is operating at high speed, the movable coupling component, subjected to centrifugal force, slides away from the axis of the second rotating shaft until it couples with the second driven rotating component, driving it to rotate at high speed. At this time, the first driven rotating component remains stationary and does not interfere with the former's rotational motion. Under this condition, the second driven rotating component can generate a large torque, fully harvesting energy from the high-speed operation. When the driving rotating component is operating at low speed, the centrifugal force on the movable coupling component is insufficient. In this case, the movable coupling component couples with the first driven rotating component located on the inner side, driving the second rotating shaft to rotate at low speed. Furthermore, the wave energy capture device can capture wave energy through the oscillating part and convert it into the rotation of the first rotating shaft. By connecting the first and second rotating shafts to the third rotating shaft respectively, and ensuring that the transmission directions of the first and second rotating shafts to the third rotating shaft are the same, the third rotating shaft is driven only by the rotation of the faster of the first and second rotating shafts. In particular, when the active rotating component is at a high speed, the wave energy capture device can convert the wave energy into the rotation of the first rotating shaft without interference and drive the third rotating shaft, thereby enabling the full collection of both wave energy and water flow energy at low flow velocities. It is understood that although wave energy has high energy density, it fluctuates violently, while water flow energy has strong regularity and predictability. The water energy capture mechanism of this invention can capture both wave energy and water flow energy simultaneously. By combining the two, the stability of water flow energy can be used to compensate for the intermittency of wave energy, thereby achieving a more stable total power output.

[0007] In some embodiments, the water flow energy capture device further includes a plurality of guide shafts extending radially along the active rotating member, wherein the proximal end of the guide shaft is disposed on the active rotating member, and the distal end of the guide shaft is provided with a limiting portion; The movable coupling member is fitted onto the guide shaft and elastically connected to the limiting part, so that the movable coupling member can be rotated by the active rotating member and reciprocate along the guide shaft by the combined force of centrifugal force and elastic force.

[0008] In some embodiments, the active rotating member has a circumferentially ...

[0009] In this invention, the limiting groove can limit the radial sliding of the movable coupling component, and the semi-enclosed structure of the limiting groove can provide a certain degree of protection for the movable coupling component. In addition, it can also improve the support strength of the guide shaft, making the reciprocating motion of the movable coupling component reliable and accurate.

[0010] In some embodiments, the first driven rotating member has an outer peripheral surface that is circumferential, and the outer peripheral surface is provided with a plurality of first grooves at intervals; Each of the movable coupling members is provided with a first protrusion facing the outer peripheral surface, and the first protrusion is embedded into the first groove when the movable coupling member is coupled to the first driven rotating member.

[0011] In this invention, the movable coupling member can be radially positioned through the first protrusion and the first groove of the first driven rotating member. Thus, the active rotating member, the movable coupling member, and the first driven rotating member form an integrated synchronous rotating motion. Furthermore, by designing the outer peripheral surface of the first driven rotating member as a circular surface, the sliding friction between the side of the movable coupling member with the first protrusion and the first driven rotating member during the transition from high-speed to low-speed operation can be reduced, ensuring that the first protrusion and the first groove are aligned and engaged.

[0012] In some embodiments, the second driven rotating member has an annular portion on the side facing the first driven rotating member, the annular portion having an inner circumferential surface that is circular, and the inner circumferential surface is provided with a plurality of second grooves at intervals. The movable coupling member extends to the inner side of the annular portion at one end facing the second driven rotating member. Each movable coupling member is provided with a second protrusion facing the inner circumferential surface. When the movable coupling member is coupled to the second driven rotating member, the second protrusion is embedded into the second groove.

[0013] In this invention, the movable coupling member can be radially positioned through the second protrusion and the second groove of the second driven rotating member. Thus, the active rotating member, the movable coupling member, and the second driven rotating member form an integral synchronous rotating motion. Furthermore, by designing the inner circumferential surface of the annular portion as a circular surface, the sliding friction between the side of the movable coupling member with the second protrusion and the second driven rotating member during the transition from low-speed to high-speed operation can be reduced, ensuring that the second protrusion and the second groove are aligned and engaged.

[0014] In some embodiments, the first transmission assembly includes a first pawl, a first driven wheel, and a first ratchet. The first driven wheel and the first ratchet are coaxially arranged. The first driven wheel is loosely fitted onto the third rotating shaft. The first ratchet is fixedly connected to the third rotating shaft. The first pawl is disposed on the first driven wheel and configured to drive the first ratchet in one direction. The first driven wheel is coupled to the first rotating shaft to transmit rotational motion through the first rotating shaft.

[0015] In some embodiments, the second transmission assembly includes a second pawl, a second driven wheel, and a second ratchet. The second driven wheel and the second ratchet are coaxially arranged. The second driven wheel is loosely fitted onto the third rotating shaft. The second ratchet is fixedly connected to the third rotating shaft. The second pawl is disposed on the second driven wheel and configured to drive the second ratchet in one direction. The second driven wheel is coupled to the second rotating shaft to transmit rotational motion through the second rotating shaft.

[0016] The second objective of this invention is to provide a hydroelectric power generation device, comprising a linkage shaft assembly, an energy storage mechanism, a transmission gear assembly, a telescopic transmission assembly, a first generator, a second generator, and the aforementioned water energy capture mechanism; The linkage shaft assembly is coaxially arranged and elastically connected to the third rotating shaft. The linkage shaft assembly is configured to transmit the torque of the third rotating shaft. The end of the linkage shaft assembly away from the third rotating shaft is provided with a drive gear that can rotate synchronously with the linkage shaft assembly. The energy storage mechanism includes a spring component and a tensioning gear coupled to the spring component. The tensioning gear can be rotated in a first direction to tighten the spring component and in a second direction driven by the elastic potential energy released by the spring component. One of the first direction and the second direction is clockwise and the other is counterclockwise. The transmission gear assembly is disposed between the drive gear and the tension gear. One side of the transmission gear assembly is always engaged with the tension gear, and the drive gear is intermittently engaged with the other side of the transmission gear assembly, so that the torque of the drive gear is transmitted to the tension gear through the transmission gear assembly when engaged. One side of the telescopic transmission assembly is coupled to the third rotating shaft, and the other side is coupled to the linkage shaft assembly. The third rotating shaft acts on the linkage shaft assembly through the telescopic transmission assembly, so that the linkage shaft assembly can reciprocate relative to the transmission gear assembly, so that the driving gear intermittently meshes with the transmission gear assembly. The second driven rotating member is coupled to the first generator, and the transmission gear assembly is coupled to the second generator.

[0017] In this invention, the linkage shaft assembly can transmit the torque generated by the rotation of the third rotating shaft to the tensioning gear via the driving gear. The spring component is then tightened, converting rotational mechanical energy into the elastic potential energy of the spring component for temporary storage. The linkage shaft assembly is then driven to retract relative to the third rotating shaft via the telescopic transmission assembly, disengaging the transmission gear assembly from the driving gear. This prevents the third rotating shaft from transmitting torque to the tensioning gear. Consequently, the spring component converts the temporarily stored elastic potential energy into mechanical energy that drives the tensioning gear to rotate, and this mechanical energy is transmitted to the second generator via the transmission gear assembly to generate electricity. Meanwhile, the torque generated by the high-speed rotation of the second driven rotating component drives the first generator to generate electricity. Thus, the hydroelectric power generation equipment of this invention can fully utilize the high and low-speed water flow energy captured by the water flow energy capture device and the wave energy captured by the wave energy capture device to generate electricity, significantly improving the hydroelectric utilization rate. In particular, by simultaneously collecting wave energy and low-speed water flow energy through the third rotating shaft, the idle rate of the second generator can be reduced, improving the power generation efficiency of the hydroelectric power generation equipment.

[0018] In some embodiments, the hydropower generation equipment further includes a bearing component loosely fitted onto the linkage shaft assembly, and the outer surface of the bearing component is connected to a transmission structure; The outer peripheral surface of the linkage shaft assembly has a first limiting part, the first limiting part is spaced apart from the drive gear, the bearing component is located between the first limiting part and the drive gear, and the first limiting part is used to prevent relative sliding between the bearing component and the linkage shaft assembly in the axial direction; The telescopic transmission assembly acts on the transmission structure, causing the bearing component to slide toward the first limiting part until it abuts and continues to act on the first limiting part, thereby driving the linkage shaft assembly to retract toward the third rotating shaft.

[0019] In this invention, the bearing component ensures reliable axial rotation of the linkage shaft assembly. Through the cooperation of the transmission structure and the first limiting part, the telescopic transmission component can drive the linkage shaft assembly to retract relative to the third rotating shaft without affecting the rotation of the linkage shaft assembly, making it easy to disengage the transmission gear assembly from the driving gear.

[0020] In some embodiments, the outer peripheral surface of the linkage shaft assembly further has a second limiting portion, which is located between the first limiting portion and the drive gear. The first limiting portion and the second limiting portion are spaced apart, and the bearing component is disposed between the first limiting portion and the second limiting portion. The second limiting portion is used to prevent the bearing component from sliding toward the drive gear.

[0021] In this invention, the first limiting part and the second limiting part constitute a sliding area of ​​the bearing component, so that when the linkage shaft assembly rebounds under the action of elastic force and acts on the bearing component, the sliding distance of the bearing component toward the direction of the driving gear is automatically controlled, thus preventing the transmission structure from exceeding the range that the telescopic transmission assembly can couple.

[0022] In some embodiments, the hydropower generation equipment further includes a guide member supported on one side of the linkage shaft assembly, the guide member extending axially along the linkage shaft assembly, and the bearing component or the transmission structure being slidably connected to the guide member so that the bearing component can reciprocate axially along the linkage shaft assembly.

[0023] In this invention, the guiding effect of the guide member can prevent the bearing component and the transmission structure from sliding circumferentially relative to the linkage shaft assembly. Thus, the stable position of the bearing component and the transmission structure can ensure reliable and accurate axial relative sliding between the linkage shaft assembly and the third rotating shaft.

[0024] In some embodiments, the transmission structure is a rack extending axially along the linkage shaft assembly; The telescopic transmission assembly is configured to engage the rack so that the rack can move along the axial direction of the linkage shaft assembly toward the third rotating shaft.

[0025] In some embodiments, the linkage shaft assembly includes a bushing and a rod connected coaxially. The bushing has an axially extending receiving cavity. The bushing houses the third rotating shaft through the receiving cavity. One end of the third rotating shaft extending into the receiving cavity is elastically connected to the end face of the receiving cavity near the rod. The bushing is telescopically movable relative to the third rotating shaft. The bushing and the third rotating shaft are circumferentially positioned by a limiting structure. The drive gear is located at the end of the rod away from the bushing.

[0026] In this invention, the telescopic transmission assembly continuously acts on the transmission structure, allowing the bearing component to abut against the first limiting part and drive the linkage shaft assembly to retract towards the third rotating shaft against the elastic force. Furthermore, when the force applied to the transmission structure by the telescopic transmission assembly is removed, the linkage shaft assembly can reset under the action of the elastic force, and the driving gear re-engages with the transmission gear assembly. In addition, by sleeve-fitting the connecting rod part, the reliability and stability of the circumferential positioning of both can be improved, ensuring the reliability of the rotational motion of the whole formed by the third rotating shaft and the linkage shaft assembly, as well as the axial relative sliding between them.

[0027] In some embodiments, the third shaft has a threaded structure extending axially; The telescopic transmission assembly includes a first fully gear and a partially gear that are connected to each other. The threaded structure meshes with the first fully gear, and the partially gear intermittently meshes with the transmission structure.

[0028] In this invention, the incomplete gear is driven by the rotation of the third rotating shaft. Based on the intermittent meshing transmission structure of the incomplete gear, the linkage shaft assembly can reciprocate relative to the third rotating shaft, avoiding the introduction of an external reciprocating drive mechanism and significantly reducing structural complexity.

[0029] In some embodiments, the telescopic transmission assembly further includes a reduction gear set, through which the first complete gear drives the incomplete gear.

[0030] In this invention, the transmission of the reduction gear set can slow down the speed of the incomplete gear meshing transmission structure, extend the time for the third rotating shaft to transmit torque to the tensioning gear through the transmission gear assembly, so that the spring component can be fully tightened, thereby increasing the storage of elastic potential energy and avoiding the increase in energy loss caused by frequent conversion between elastic potential energy and mechanical energy.

[0031] In some embodiments, the driving gear is a first bevel gear, and the transmission gear assembly includes a second bevel gear and a second complete gear arranged coaxially, wherein the second bevel gear and the second complete gear are configured to rotate synchronously; The first bevel gear meshes with the second bevel gear, the second full gear meshes with the tension gear, and the second full gear is coupled to the second generator.

[0032] In this invention, the meshing of the first bevel gear and the second bevel gear can change the power transmission direction of the shaft assembly, allowing the drive gear, transmission gear assembly and tension gear to be arranged in a compact manner, and the transmission efficiency is high. This can improve the efficiency of converting the rotational mechanical energy of the third shaft into the elastic potential energy of the spring component, and it is also easy to disengage the first bevel gear and the second bevel gear through a small axial movement of the linkage shaft assembly.

[0033] In some embodiments, the hydroelectric power generation equipment further includes an acceleration gear set, and the transmission gear assembly is connected to the first generator via the acceleration gear set.

[0034] It can be understood that when the elastic potential energy stored in the spring component is converted into the rotational mechanical energy of the tensioning gear, the tensioning gear generates "high torque-low speed" mechanical energy. Through the acceleration gear set, this "high torque-low speed" mechanical energy can be converted into "low torque-high speed" mechanical energy, which is then transmitted to the second generator to maximize the conversion from elastic potential energy to electrical energy.

[0035] Compared with the prior art, the beneficial effects of the present invention are as follows: Based on the different centrifugal forces generated on the movable coupling component at different rotation speeds of the active rotating component, the movable coupling component can automatically couple with one of the first driven rotating component and the second driven rotating component, and rotate together. This allows the water flow energy to be captured at both low and high water flow velocities through the water flow energy capture device. Furthermore, through the organic combination of the third rotating shaft, the first transmission assembly, the second transmission assembly, and the second rotating shaft, both wave energy and water flow energy can be captured simultaneously. The stability of the water flow energy compensates for the intermittent nature of the wave energy, thereby achieving a more stable total power output. In addition, through the meshing structure of the third rotating shaft and the intermittent meshing connection of the rack and pinion with the telescopic transmission assembly having incomplete gears, the linkage shaft assembly can be driven to slide axially relative to the third rotating shaft based on the rotational motion of the third rotating shaft itself. This allows for the autonomous and efficient storage and release of mechanical energy generated under low water flow conditions and wave energy. Attached Figure Description

[0055] Example 1 like Figure 1-5 As shown, this embodiment provides a water capture mechanism, including: The wave energy capture device 110 includes a swinging part 111 and a rotating part 112 that are movably connected to each other. The swinging part 111 can drive the rotating part 112 to rotate by swinging up and down. The rotating part 112 is coaxially connected to a first rotating shaft 112a. The water flow energy capture device 120 includes several movable coupling members 125 and a coaxially arranged active rotating member 121, a first driven rotating member 122, and a second driven rotating member 123. The active rotating member 121, the first driven rotating member 122, and the second driven rotating member 123 are arranged sequentially back and forth along the axial direction. The center of the first driven rotating member 122 is fixedly connected to a second rotating shaft 124, and the second driven rotating member 123 is loosely fitted on the second rotating shaft 124. Several movable coupling members 125 are disposed on the active rotating member 121. The ends of the movable coupling members 125 away from the active rotating member 121 extend sequentially through the space where the first driven rotating member 122 and the second driven rotating member 123 are located. Furthermore, the several movable coupling members 125 are distributed at intervals along the outer periphery of the first driven rotating member 122. When the active rotating member 121 rotates, it can drive the movable coupling members 125, so that the movable coupling members 125 are coupled and rotate to drive the first driven rotating member 122 or the second driven rotating member 123. The third rotating shaft 130 is connected to the first rotating shaft 112a via a first transmission assembly and to the second rotating shaft 124 via a second transmission assembly, wherein the first transmission assembly and the second transmission assembly transmit power to the third rotating shaft 130 in the same direction.

[0056] It can be understood that by fixing the first driven rotating member 122 to the second rotating shaft 124 and loosely fitting the second driven rotating member 123 onto the second rotating shaft 124, one of the first driven rotating member 122 and the second driven rotating member 123 can rotate while the other remains stationary. In actual use, the side of the driving rotating member 121 facing away from the first driven rotating member 122 is provided with a driving rotating shaft 121a, and the end of the driving rotating shaft 121a is provided with a blade 121c or a similar force-bearing structure. When external water flow, tidal energy, etc. pass through this force-bearing structure... When the active rotating component 121 rotates, the movable coupling component 125 can rotate synchronously. When the active rotating component 121 is at a high speed, the movable coupling component 125 is subjected to centrifugal force and can slide away from the axis of the second rotating shaft 124 until it is coupled to the second driven rotating component 123, driving it to rotate at high speed. At this time, the first driven rotating component 122 remains stationary and does not interfere with the rotation of the former. Under this condition, the second driven rotating component 123 can generate a large torque, fully harvesting energy under high speed conditions. When the active rotating component 121 is at a low speed, the centrifugal force on the movable coupling component 125 is insufficient. At this time, the movable coupling component 125 is coupled to the first driven rotating component 122 located on the inner side, driving the second rotating shaft 124 to rotate at a low speed. Furthermore, the wave energy capture device 110 can capture wave energy generated by undulating motion through the swinging part 111 and convert it into rotation of the first rotating shaft 112a. By connecting the first rotating shaft 112a and the second rotating shaft 124 to the third rotating shaft 130 respectively, and making the transmission directions of the two shafts to the third rotating shaft 130 the same, the third rotating shaft 130 is driven only by the rotation of the faster rotating shaft between the first rotating shaft 112a and the second rotating shaft 124. In particular, when the active rotating member 121 is at a high speed, the wave energy capture device 110 can convert the wave energy into rotation of the first rotating shaft 112a without interference and drive the third rotating shaft 130, thereby enabling the full collection of both wave energy and low-velocity water flow energy. It is understood that wave energy is usually generated by wave action. Although it has high energy density, it fluctuates violently. Water flow energy, on the other hand, has strong regularity and predictability. The water energy capture mechanism of the present invention can capture both wave energy and water flow energy at the same time. By driving the second driven rotating member 123 and the third rotating shaft 130 to different generators respectively, the different rotation speeds of the active rotating member 121 and the wave energy collected by the swing part 111 can be fully utilized to generate electricity. The present invention can compensate for the intermittency of wave energy by stabilizing water flow energy, thereby achieving a more stable total power output.

[0057] In this embodiment, the swinging part 111 and the rotating part 112 are connected by a connecting rod 113, and the three constitute a crank-rocker mechanism. When the water energy capture mechanism is applied to an underwater environment, the swinging water energy capture mechanism is driven to move up and down by waves. The swinging part 111 can swing up and down, and the rotating part 112 is driven by the connecting rod 113, so that the rotating part 112 drives the first rotating shaft 112a to rotate.

[0058] refer to Figure 2 In this embodiment, the first transmission assembly includes a first pawl 112b, a first driven wheel 112c, and a first ratchet 112d. The first driven wheel 112c and the first ratchet 112d are coaxially arranged. The first driven wheel 112c is loosely fitted onto the third rotating shaft 130. The first ratchet 112d is fixedly connected to the third rotating shaft 130. The first pawl 112b is disposed on the first driven wheel 112c and configured to drive the first ratchet 112d in one direction. The first driven wheel 112c is coupled to the first rotating shaft 112a to transmit rotational motion through the first rotating shaft 112a. In some simplified structures, the second transmission assembly includes a second driven wheel 123c, a second ratchet, and a second pawl. The second driven wheel 123c and the second ratchet are coaxially arranged and both are fixedly mounted on the third rotating shaft 130. The second pawl is configured to drive the second ratchet in one direction. The second driven wheel 123c is coupled to the second rotating shaft 124 to transmit rotational motion through the second rotating shaft 124.

[0059] In this embodiment, when the rotational speed of the second rotating shaft 124 is faster than that of the first rotating shaft 112a, the third rotating shaft 130 is driven by the second rotating shaft 124. At this time, the third rotating shaft 130 rotates synchronously, driving the first ratchet 112d. Since the rotational speed of the first ratchet 112d is faster than that of the first driven wheel 112c, the first pawl 112b cannot engage the teeth of the first ratchet 112d, but instead continuously "overtakes" and slips on the back of the teeth of the first ratchet 112d. Therefore, the first transmission wheel will not produce any deceleration or resistance to the third rotating shaft 130. When the rotational speed of the first rotating shaft 112a is faster than that of the second rotating shaft 124, the first driven wheel 112c rotates, driving the first pawl 112b. The first pawl 112b engages with the first ratchet 112d, thereby driving the first ratchet 112d, and thus driving the third rotating shaft 130 to rotate.

[0060] In a preferred embodiment, the second transmission assembly can refer to the configuration of the first transmission assembly: the second driven wheel 123c is loosely fitted onto the third rotating shaft 130, the second ratchet is fixedly connected to the third rotating shaft 130, the second pawl is provided on the second driven wheel 123c, and configured as a one-way transmission second ratchet; wherein, the second driven wheel 123c is coupled to the second rotating shaft 124 to transmit rotational motion through the second rotating shaft 124. Thus, when the rotational speed of the first shaft 112a is faster than that of the second shaft 124, the rotation of the first driven wheel 112c drives the first pawl 112b, which in turn engages the first ratchet 112d, thereby driving the first ratchet 112d and in turn driving the third shaft 130 to rotate. At this time, the third shaft 130 rotates synchronously, driving the second ratchet. Since the rotational speed of the second ratchet is faster than that of the second driven wheel 123c, the second pawl cannot engage the teeth of the second ratchet, but instead continuously "overtakes" and slips on the back of the teeth of the second ratchet. Therefore, the second drive wheel will not produce any deceleration or resistance to the third shaft 130.

[0061] In this embodiment, a gear component or gear set is fixedly mounted on the first rotating shaft 112a, and the first driven gear is connected to it via the gear component or gear set. In some embodiments, refer to... Figure 2 Alternatively, a ratchet and pawl assembly 112e can be configured on the first rotating shaft 112a so that it can only rotate in one direction, thereby driving the first driven wheel 112c in one direction.

[0062] refer to Figure 4-5 In this embodiment, the water flow energy capture device 120 further includes a plurality of guide shafts 140 extending radially along the active rotating member 121, wherein the proximal end of the guide shaft 140 is disposed on the active rotating member 121, and the distal end of the guide shaft 140 is provided with a limiting part. The movable coupling member 125 is fitted onto the guide shaft 140 and elastically connected to the limiting part, so that the movable coupling member 125 can be rotated by the active rotating member 121 and reciprocate along the guide shaft 140 under the combined force of centrifugal force and elastic force. In a specific implementation, a first elastic member 150 is provided between the movable coupling member 125 and the limiting part to achieve an elastic connection. For example, the first elastic member 150 can be implemented as a spring sleeve fitted onto the guide shaft 140.

[0063] Understandable, for reference Figure 5 When the active rotating member 121 rotates at a relatively high speed, the centrifugal force on the movable coupling member 125 can overcome the elastic force of the first elastic member 150. Therefore, the movable coupling member 125 slides outward along the guide shaft 140 until it couples with the second driven rotating member 123 and drives it to rotate. At this time, the first driven rotating member 122 remains relatively stationary and does not interfere with the rotational motion of the former. (Reference) Figure 4When the rotational speed of the active rotating member 121 is relatively slow, the elastic force on the movable coupling member 125 is greater than the centrifugal force. At this time, the movable coupling member 125 is squeezed towards the first driven rotating member 122 by the elastic force of the first elastic member 150, so that the movable coupling member 125 is coupled to the first driven rotating member 122 and drives it to rotate. Similarly, at this time, the second driven rotating member 123 remains relatively stationary and does not interfere with the rotational motion of the first driven rotating member 122.

[0064] refer to Figure 4-6 In specific implementation, the active rotating member 121 has a circumferentially ...

[0065] In specific implementation, the first active rotating component 121 includes an active rotating shaft 121a and an active rotating seat 121b, with the active rotating shaft 121a fixed to the center of the active rotating seat 121b, combined with... Figure 5 It is understood that the limiting groove 121d is circumferentially arranged on the side of the active rotating seat 121b facing the first driven rotating member 122. At this time, the end of the active rotating shaft 121a is used to connect the blade 121c.

[0066] In this embodiment, the first driven rotating member 122 has an outer peripheral surface 122a in the shape of a circumferential surface, and a plurality of first grooves 122b are provided at intervals on the outer peripheral surface 122a; Each movable coupling member 125 is provided with a first protrusion 125a facing the outer peripheral surface 122a. The first protrusion 125a is embedded into the first groove 122b when the movable coupling member 125 is coupled to the first driven rotating member 122.

[0067] It is understandable that when the active rotating member 121 is at a low speed, the elastic force on the movable coupling member 125 is greater than the centrifugal force. At this time, the first elastic member 150 squeezes the movable coupling member 125, causing the movable coupling member 125 to press against the outer peripheral surface 122a of the first driven rotating member 122. Driven by the active rotating member 121, the movable coupling member 125 slides circumferentially along the outer peripheral surface 122a until the first protrusion 125a of the movable coupling member 125 corresponds one-to-one with the first groove 122b of the first driven rotating member 122. Then, through the squeezing action of the first elastic member 150, the first protrusion 125a is embedded into the corresponding first groove 122b. Thus, the active rotating member 121, the movable coupling member 125, and the first driven rotating member 122 form a whole synchronous rotating motion.

[0068] refer to Figure 4-5 In this embodiment, the second driven rotating member 123 is provided with an annular portion 123a on the side facing the first driven rotating member 122. The annular portion 123a has an inner circumferential surface that is circular, and a plurality of second grooves 123b are provided at intervals on the inner circumferential surface. The movable coupling member 125 extends to the inner side of the annular portion 123a at one end toward the second driven rotating member 123. Each movable coupling member 125 is provided with a second protrusion 125b toward the inner circumferential surface. When the movable coupling member 125 is coupled to the second driven rotating member 123, the second protrusion 125b is embedded into the second groove 123b.

[0069] In a preferred embodiment, the second driven rotating member 123 is a turntable with a cavity, the opening of the cavity facing the first driven rotating member 122, the first driven rotating member 122 is located at the center of the cavity, the first driven rotating member 122 extends at least partially into the cavity, and the first driven rotating member 122 is coaxially arranged with the cavity. At this time, an annular groove is formed between the cavity and the outer circumferential surface of the first driven rotating member 122, and the movable coupling member 125 extends into the annular groove at one end facing the second driven rotating member.

[0070] When the active rotating member 121 is at a high speed, the centrifugal force on the movable coupling member 125 is greater than the elastic force applied by the first elastic member 150. At this time, the movable coupling member 125 is mainly subjected to centrifugal force. The movable coupling member 125 slides along the guide shaft 140 until it abuts against the inner circumferential surface of the annular portion 123a. Driven by the active rotating member 121, the movable coupling member 125 slides relative to the inner circumferential surface until the second protrusion 125b of the movable coupling member 125 corresponds one-to-one with the second groove 123b of the second driven rotating member 123. Based on the centrifugal force, the second protrusion 125b is embedded into the corresponding second groove 123b. Thus, the active rotating member 121, the movable coupling member 125, and the second driven rotating member 123 constitute an integral synchronous rotating motion.

[0071] refer to Figure 6-7 In a preferred embodiment, the movable coupling member 125 is an arc block, and the arc block has a through hole at the corresponding arc apex that penetrates the inner and outer arc surfaces. The guide shaft 140 passes through the through hole and engages with the arc. Figure 7 It is understood that the first protrusion 125a is provided on the inner arc surface of the movable coupling member 125, and the second protrusion 125b is provided on the outer arc surface of the movable coupling member 125. In this way, through the supporting effect of the first protrusion 125a, the inner arc surface of the movable coupling member 125 can easily form a gap with the outer peripheral surface 122a of the first driven rotating member 122, which can reduce the friction between the movable coupling member 125 and the first driven rotating member 122 when the movable coupling member 125 rotates circumferentially. Similarly, through the supporting effect of the second protrusion, the outer arc surface of the movable coupling member 125 can easily form a gap with the outer peripheral surface 122a of the second driven rotating member 123. Thus, the process of the movable coupling member 125 switching to couple with the first driven rotating member 122 and the second driven rotating member 123 is smooth and reliable.

[0072] refer to Figure 3-5 In this specific implementation, by positioning the rotating seat 121b opposite to the turntable-shaped second driven rotating member 123 with a gap, the limiting groove 121d of the active rotating member 121 corresponds to the annular portion 123a of the second driven rotating member 123. At this time, the movable coupling member 125 is completely limited within the accommodating space formed by the limiting groove 121d and the annular portion 123a, so that the movable coupling member 125 can be limited within the set space when performing circumferential rotation and radial sliding, improving the reliability and efficiency of the switching coupling process between the movable coupling member 125 and the first driven rotating member 122 and the second driven rotating member 123.

[0073] Example 2 refer to Figure 8-11 This embodiment proposes a hydropower generation device, including a linkage shaft assembly 200, an energy storage mechanism 300, a transmission gear assembly 400, a telescopic transmission assembly 500, a first generator 600, a second generator 700, and a hydropower capture mechanism 100 of Embodiment 1. The linkage shaft assembly 200 is coaxially arranged and elastically connected with the third rotating shaft 130. The linkage shaft assembly 200 is configured to transmit the torque of the third rotating shaft 130. The end of the linkage shaft assembly 200 away from the third rotating shaft 130 is provided with a drive gear 210 that can rotate synchronously with the linkage shaft assembly 200. The energy storage mechanism 300 includes a spring component 310 and a tensioning gear 320 coupled to the spring component 310. Specifically, the tensioning gear 320 can rotate to tighten the spring component 310 by rotating in a first direction and rotate in a second direction under the drive of the elastic potential energy released by the spring component 310. One of the first direction and the second direction is clockwise and the other is counterclockwise. The transmission gear assembly 400 is located between the drive gear 210 and the tension gear 320. One side of the transmission gear assembly 400 is always engaged with the tension gear 320, while the drive gear 210 is intermittently engaged with the other side of the transmission gear assembly, so that the torque of the drive gear 210 is transmitted to the tension gear 320 through the transmission gear assembly 400 during engagement. One side of the telescopic transmission assembly 500 is coupled to the third rotating shaft 130, and the other side is coupled to the linkage shaft assembly 200. The third rotating shaft 130 acts on the linkage shaft assembly 200 through the telescopic transmission assembly 500, so that the linkage shaft assembly 200 can reciprocate relative to the transmission gear assembly 400, so that the driving gear 210 intermittently meshes with the transmission gear assembly 400. The second driven rotating component 123 is coupled to the first generator 600, and the transmission gear assembly 400 is coupled to the second generator 700.

[0074] refer to Figure 14 In this embodiment, the tensioning gear 320 has a circumferentially arranged limiting ring 321. The center of the mainspring component 310 is connected to the axis of the mainspring tensioning gear 320, and the outer end of the mainspring component 310 is connected to the inner wall of the limiting ring 321. In actual use, the axis of the mainspring tensioning gear 320 is rotatably supported by an external support structure through bearing components. It can be understood that the energy storage mechanism 300 can also be implemented using a conventional mainspring disc structure.

[0075] In specific implementation, the hydroelectric power generation equipment of the present invention mainly works in conjunction with a floating platform. For example, the hydroelectric power generation equipment is installed on a mooring line and submerged in water for use. Therefore, a sealed housing 800 is used as the installation frame. The housing 800 is hollow to form a sealed cavity. It can be understood that, in order to ensure waterproof performance, in this embodiment, only the end of the active rotating member 121 with blades 121c and the swing part 111 are exposed outside the sealed cavity to capture water energy. Apart from this, other components of the water energy capture mechanism 100, as well as the linkage shaft assembly 200, energy storage mechanism 300, transmission gear assembly 400, telescopic transmission assembly 500, first generator 600, and second generator 700 are only located inside the sealed cavity.

[0076] During implementation, refer to Figure 15To shorten the power supply distance, the hydroelectric power generation equipment primarily supplies power to the underwater electrical device 900. For example, the underwater electrical device 900 is detachably connected to the housing 800 of the hydroelectric power generation equipment. This facilitates internal wiring of the power supply lines between the first generator 600, the second generator 700, and the underwater electrical device 900, enhancing waterproofing and simplifying the wiring layout. It is understood that the hydroelectric power generation equipment also includes an energy storage device located inside the housing 800 and connected to the first generator 600 and the second generator 700, used to temporarily store the electrical energy generated by these generators. In this case, the underwater electrical device 900 is electrically connected to the energy storage device via a power supply line.

[0077] Preferably, the underwater electrical device 900 is provided with a conductive structure 910. In use, the mooring line can be threaded through the conductive structure 910, so that the underwater electrical device 900 and the hydroelectric power generation equipment can slide along the mooring line. Thus, when the buoy tied to the mooring line drifts, the mooring line is also pulled. The mooring line acts on the underwater electrical device 900 and the hydroelectric power generation equipment, which on the one hand, causes the hydroelectric power generation equipment to rise and fall in the water, so that the water force acts on the swing part 111, causing it to swing up and down. On the other hand, it can also cause the hydroelectric power generation equipment to move horizontally, so that the water flow acts on the blade 121c, causing the active rotating part 121 to rotate.

[0078] In some other embodiments, the conductive structure 910 may be directly provided on the outer wall of the housing 800.

[0079] In this embodiment, the linkage shaft assembly 200 transmits the torque generated by the rotation of the third rotating shaft 130 to the tensioning gear 320 via the drive gear 210. This tightens the spring component 310, converting rotational mechanical energy into the elastic potential energy of the spring component 310 for temporary storage. The telescopic transmission assembly 500 then drives the linkage shaft assembly 200 to retract relative to the third rotating shaft 130. The transmission gear assembly 400 disengages from the drive gear 210, preventing the third rotating shaft 130 from transmitting torque to the tensioning gear 320. Thus, the spring component 310 can convert the temporarily stored elastic potential energy into energy to drive the tensioning gear 320. The mechanical energy of the rotational motion is transmitted to the second generator 700 via the transmission gear assembly 400 to generate electricity; while the torque generated by the high-speed rotation of the second driven rotating member 123 transmits the torque to the first generator 600 to generate electricity. Thus, the hydropower generation equipment of the present invention can fully utilize the high and low speed water flow energy captured by the water flow energy capture device 120 and the wave energy captured by the wave energy capture device 110 to generate electricity, significantly improving the water energy utilization rate. In particular, by simultaneously collecting low speed water flow energy and wave energy through the third rotating shaft 130, the idle rate of the second generator 700 can be reduced, and the power generation efficiency of the hydropower generation equipment can be improved.

[0080] refer to Figure 11 The hydropower generation equipment also includes a bearing component 220 that is loosely fitted into the linkage shaft assembly 200, and a transmission structure 221 is connected to the outer surface of the bearing component 220. The outer peripheral surface 122a of the linkage shaft assembly 200 has a first limiting part 230, which is spaced apart from the drive gear 210. The bearing component 220 is located between the first limiting part 230 and the drive gear 210. The first limiting part 230 is used to prevent relative sliding between the bearing component 220 and the linkage shaft assembly 200 in the axial direction. The telescopic transmission component 500 acts on the transmission structure 221, causing the bearing component 220 to slide toward the first limiting part 230 until it abuts and continues to act on the first limiting part 230, so as to drive the linkage shaft component 200 to retract toward the third rotating shaft 130.

[0081] It is understood that the bearing component 220 can ensure the reliable axial rotation of the linkage shaft assembly 200. Through the cooperation of the transmission structure 221 and the first limiting part 230, the telescopic transmission component 500 can drive the linkage shaft assembly 200 to retract relative to the third rotating shaft 130 without affecting the rotation of the linkage shaft assembly 200, and easily realize the disengagement of the transmission gear assembly 400 from the drive gear 210.

[0082] In some embodiments, the outer peripheral surface 122a of the linkage shaft assembly 200 further has a second limiting portion 240, which is located between the first limiting portion 230 and the drive gear 210. The first limiting portion 230 and the second limiting portion 240 are spaced apart, and a bearing component 220 is disposed between the first limiting portion 230 and the second limiting portion 240. The second limiting portion 240 is used to prevent the bearing component 220 from sliding towards the drive gear 210. In a specific implementation, the second limiting portion 240 is an annular member surrounding the outer peripheral surface 122a of the rod portion 270.

[0083] In this invention, the first limiting part 230 and the second limiting part 240 form a sliding area of ​​the bearing component 220, so that when the linkage shaft assembly 200 rebounds under the action of elastic force and acts on the bearing component 220, the sliding distance of the bearing component 220 toward the drive gear 210 is automatically controlled, so as to prevent the transmission structure 221 from exceeding the range that the telescopic transmission assembly 500 can be coupled.

[0084] refer to Figure 12 The hydropower generation equipment also includes a guide member 250 supported on one side of the linkage shaft assembly 200. The guide member 250 extends along the axial direction of the linkage shaft assembly 200. The bearing component 220 or the transmission structure 221 is slidably connected to the guide member 250 so that the bearing component 220 can reciprocate along the axial direction of the linkage shaft assembly 200.

[0085] In a specific implementation, the guide member 250 is fixed to the inner wall of the housing 800. Based on the supporting role of the housing 800 and the guiding role of the guide member 250, circumferential sliding between the bearing component 220 and the transmission structure 221 and the linkage shaft assembly 200 can be avoided, ensuring reliable and accurate axial relative movement between the linkage shaft assembly 200 and the third rotating shaft 130. In a preferred embodiment, the guide member 250 has a guide groove 251, the extension direction of which is parallel to the axial direction of the linkage shaft assembly 200. One side of the transmission structure 221 has a guide protrusion, and the transmission structure 221 is slidably disposed in the guide groove 251 through the guide protrusion.

[0086] like Figure 11 , 12 As shown, in this embodiment, the transmission structure 221 is a rack extending along the axial direction of the linkage shaft assembly 200; the telescopic transmission assembly 500 is configured to engage the transmission rack so that the rack can move along the axial direction of the linkage shaft assembly 200 toward the third rotating shaft 130.

[0087] refer to Figure 13 In this embodiment, the linkage shaft assembly 200 includes a bushing 260 and a rod 270 coaxially connected. The bushing 260 has a receiving cavity extending axially. The bushing 260 is fitted with a third rotating shaft 130 through the receiving cavity. One end of the third rotating shaft 130 extending into the receiving cavity is elastically connected to the end face of the receiving cavity near the rod 270 through a second elastic member 280. The bushing 260 can extend and retract relative to the third rotating shaft 130. The bushing 260 and the third rotating shaft 130 are circumferentially positioned by a limiting structure. The drive gear 210 is located at the end of the rod 270 away from the bushing 260.

[0088] In this invention, the telescopic transmission assembly 500 continuously acts on the transmission structure 221, and the bearing component 220 can abut against the first limiting part 230 and drive the linkage shaft assembly 200 to overcome the elastic force of the second elastic element 280, thereby retracting towards the third rotating shaft 130. In addition, when the force applied to the transmission structure 221 by the telescopic transmission assembly 500 is removed, the linkage shaft assembly 200 can be reset by the elastic force of the second elastic element 280, and the drive gear 210 re-engages with the transmission gear assembly 400. Furthermore, by sleeved with the bushing 260, the reliability and stability of the circumferential positioning of the two can be improved, so that the rotational movement of the whole composed of the third rotating shaft 130 and the linkage shaft assembly 200 and the axial relative sliding between the two have high reliability.

[0089] In a preferred embodiment, the diameter of the rod 270 is smaller than that of the bushing 260, such that the connection between the bushing 260 and the rod 270 forms a first limiting portion 230, and the bearing component 220 is loosely fitted onto the rod 270. It is readily understood that the cross-section of the bushing 260 and the cross-section of the rod 270 form a concentric circle structure. Thus, the outer annular portion 123a of the concentric circle structure can provide a reliable axial limiting effect on the bearing component 220.

[0090] refer to Figure 10-11 The third rotating shaft 130 has a threaded structure 131 that extends axially; The telescopic transmission assembly 500 includes a first fully engaged gear 510 and a partially engaged gear 520 that are connected to each other. A threaded structure 131 engages with the first fully engaged gear 510, and the partially engaged gear 520 is intermittently connected to the transmission structure 221. In a specific implementation, the third rotating shaft 130 is implemented using a screw.

[0091] In use, the rotation of the third rotating shaft 130 drives the incomplete gear 520. Based on the intermittent meshing transmission structure 221 of the incomplete gear 520, the linkage shaft assembly 200 can reciprocate relative to the third rotating shaft 130. In this way, the introduction of an external reciprocating drive mechanism can be avoided, and the structural complexity can be significantly reduced.

[0092] refer to Figure 11 In this embodiment, the telescopic transmission assembly 500 also includes a reduction gear set 530, through which the first complete gear 510 drives the incomplete gear 520.

[0093] It is understandable that by using the reduction gear set 530 to drive, the speed of the incomplete gear 520 meshing transmission structure 221 can be slowed down, and the time for the third rotating shaft 130 to transmit torque to the tensioning gear 320 through the transmission gear assembly 400 can be extended, so that the spring component 310 can be fully tightened, thereby increasing the amount of elastic potential energy stored and avoiding the increase in energy loss caused by frequent conversion between elastic potential energy and mechanical energy.

[0094] refer to Figure 11 In this embodiment, the driving gear 210 is a first bevel gear, and the transmission gear assembly 400 includes a second bevel gear 410 and a second complete gear 420 arranged coaxially, and the second bevel gear 410 and the second complete gear 420 are configured to rotate synchronously. The first bevel gear meshes with the second bevel gear 410, the second complete gear 420 meshes with the tension gear 320, and the second complete gear 420 is coupled to the second generator 700.

[0095] It is understood that by meshing the first bevel gear and the second bevel gear 410, the power transmission direction of the linkage shaft assembly 200 can be changed, so that the driving gear 210, the transmission gear assembly 400 and the tension gear 320 can be arranged in a compact manner, and the transmission efficiency is high. This can improve the efficiency of converting the rotational mechanical energy of the third rotating shaft 130 into the elastic potential energy of the spring component 310, and it is also easy to disengage the first bevel gear and the second bevel gear 410 by a small axial movement of the linkage shaft assembly 200.

[0096] refer to Figure 11 In this embodiment, the hydropower generation equipment also includes an acceleration gear set 710, and the transmission gear assembly 400 is connected to the first generator 600 through the acceleration gear set 710.

[0097] It is understandable that when the elastic potential energy stored in the spring component 310 is converted into the rotational mechanical energy of the tension gear 320, the tension gear 320 generates "high torque-low speed" mechanical energy. Through the acceleration gear set 710, this "high torque-low speed" mechanical energy can be converted into "low torque-high speed" mechanical energy, which is then transmitted to the second generator 700 to maximize the conversion from elastic potential energy to electrical energy.

[0098] The working principle of the hydroelectric power generation equipment of the present invention is as follows: In use, the hydroelectric power generation equipment can be attached to the mooring line of a buoy. For example, the buoy is floated on a predetermined ocean surface, various marine scientific research equipment is installed on the buoy, and the buoy is anchored to an underwater anchoring system via the mooring line. When the active rotating component 121 rotates at low speed, the movable coupling component 125 couples with the first driven rotating component 122. The active rotating component 121 drives the first driven rotating component 122 through rotation, causing the second rotating shaft 124 to rotate. If the buoy drifts, the mooring line can cause the hydroelectric power generation equipment to undulate underwater, thereby causing the wave energy capture device 110 to drive the second rotating shaft 124 to rotate. Based on the cooperation of the first transmission component and the second transmission component, the faster rotating shaft 112a and the second rotating shaft 124 can rotate and drive the third rotating shaft 130 and the linkage shaft assembly 200. Overall, the drive gear 210 is initially connected to the tensioning gear 320 via the second bevel gear 410 of the transmission gear assembly 400, thereby transmitting the torque generated by the rotation of the linkage shaft assembly 200 to the tensioning gear 320, which then tightens the spring component 310, converting the rotational mechanical energy into the elastic potential energy of the spring component 310 for temporary storage. It should be noted that since the spring component 310 can only be tightened by unidirectional rotation of the tensioning gear 320, the first transmission assembly and the second transmission assembly are also configured to output torque to the third rotating shaft 130 in only one direction. For example, this can be achieved by the ratchet and pawl assembly 112e.

[0099] Meanwhile, the third rotating shaft 130 rotates synchronously through the threaded structure 131, driving the first fully driven gear 510. The first fully driven gear 510 slowly drives the incomplete gear 520 to rotate through the reduction gear set 530. Initially, the teeth of the incomplete gear 520 are not engaged with the rack. The driving gear 210 can continuously transmit torque to the tensioning gear 320 through the transmission gear assembly 400. After the third rotating shaft 130 has rotated for a period of time, the teeth of the incomplete gear 520 can engage with the rack and drive the bearing component 220 to move axially toward the third rotating shaft 130. The continuous action on the first limiting part 230 causes the linkage shaft assembly 200 to retract relative to the third rotating shaft 130, causing the driving gear 210 to disengage from the second bevel gear 410 of the transmission gear assembly 400. It can be understood that during this process, the linkage shaft assembly 200 no longer transmits torque to the tension gear 320. In this way, the spring component 310 can convert the temporarily stored elastic potential energy into mechanical energy to drive the tension gear 320 to rotate, and transmit the torque to the acceleration gear set 710 through the second full gear 420 of the transmission gear assembly 400, which in turn drives the first generator 600 to generate electricity. Until the teeth of the incomplete gear 520 completely disengage from the rack, the linkage shaft assembly 200 springs back to its initial position under the elastic force of the second elastic member 280. Thus, the driving gear 210 of the first bevel gear re-engages with the second bevel gear 410 of the transmission gear assembly 400. The driving gear 210 can then transmit torque to the tension gear 320 through the transmission gear assembly 400. During this process, the bearing component 220 slides toward the driving gear 210 under the action of the first limiting part 230 and is blocked by the second limiting part 240, eventually stopping between the first limiting part 230 and the second limiting part 240, ensuring that it can be intermittently meshed and transmitted by the incomplete gear 520.

[0100] It is understandable that if only one of the first rotating shaft 112a and the second rotating shaft 124 is rotating, it can also drive the third rotating shaft 130. In this way, the utilization rate of the second generator 700 can be improved, and the power generation efficiency of the hydropower generation equipment can be improved.

[0101] When the active rotating member 121 rotates at high speed, the movable coupling member 125 is coupled to the second driven rotating member 123, thereby the second driven rotating member 123 drives the first generator 600 to generate electricity through the acceleration gear set 710. It can be understood that during this process, the wave energy capturing device 110 can also capture wave energy normally and drive the third rotating shaft 130 through the second rotating shaft 124, so that the second generator 700 is also in a normal power generation state.

[0102] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention should be included within the protection scope of the claims of the present invention.
