Description

Technical Field

[0001] This application relates to the field of bridge engineering technology, specifically to a protective power generation device for a cross-sea bridge pier. Background Technology

[0002] With the development of bridge design, research, and construction technology in my country, the construction of cross-sea bridges has become an important aspect of bridge development, with the number of various cross-sea bridges constantly increasing. Cross-sea bridges are generally long-span bridges with numerous piers, and the bridge sites are often characterized by high winds and waves. Waves contain abundant energy, and if allowed to act directly on the bridge structure, they will generate significant wave-current forces, requiring a substantial increase in the design standards and investment for bridge safety and durability. To ensure the safety of the bridge structure, suitable anti-collision and wave-damping devices are necessary. Furthermore, if wave energy can be fully utilized at the bridge site for power generation, it will be particularly valuable in the current global context of energy shortages, depletion of fossil fuels, and increasingly deteriorating environmental conditions. Compared with existing power generation methods, wave energy generation does not pollute the environment, and wave energy reserves are abundant.

[0003] Therefore, those skilled in the art urgently need to develop a protective device for cross-sea bridges that can both dissipate impact energy and generate wave power, based on the two aspects of wave energy utilization and impact energy dissipation and collision prevention. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this application is to provide a protective power generation device for cross-sea bridge piers, which can simultaneously achieve impact energy dissipation and collision prevention and wave energy generation, and has high energy conversion efficiency.

[0005] To achieve the above objectives, the technical solution adopted is: a protective power generation device for cross-sea bridge piers, comprising:

[0006] A floating enclosure device that can be floated and fitted onto the cross-sea bridge pier;

[0007] A power generation conversion device is inserted through the floating device, and a power conversion wheel is provided at the bottom of the power generation conversion device;

[0008] The cantilever device is slidably mounted on the cross-sea bridge pier and located below the floating cofferdam device;

[0009] A flexible steel cable has an additional counterweight fixedly connected to one end and a cantilever device fixedly connected to the other end. The additional counterweight hangs down circumferentially from the cantilever device, and a power conversion wheel is wound around the middle of the flexible steel cable.

[0010] When the waves cause relative motion between the floating device and the cantilever device, the power conversion wheel rotates under the action of the flexible steel cable, and the power generation conversion device generates electricity.

[0011] Based on the above technical solution, the protective power generation device also includes a honeycomb damper integrated module, which is located in the center of the floating enclosure device, and the floating enclosure device is fitted onto the cross-sea bridge pier through the honeycomb damper integrated module.

[0012] Based on the above technical solution, a rubber ring is provided between the honeycomb damper integrated module and the floating device.

[0013] Based on the above technical solution, the floatation device is circular with a rectangular hole in the center; the honeycomb damper integrated module is rectangular and is installed in the rectangular hole of the floatation device.

[0014] Based on the above technical solution, the protective power generation device also includes a slip ring structure, which is located in the center of the cellular damper integrated module, and the cellular damper integrated module can be slidably fitted onto the cross-sea bridge pier through the slip ring structure.

[0015] Based on the above technical solution, the cantilever device includes a large cantilever and a rigid support rod. The large cantilever is slidably sleeved on the cross-sea bridge pier and extends away from the cross-sea bridge pier. A part of the rigid support rod is fixed to the large cantilever and is arranged outward. An elbow hinge is provided at the outwardly extending end of the rigid support rod, and the middle part of the flexible steel cable is also wrapped around the elbow hinge.

[0016] Based on the above technical solution, the cantilever device also includes a short cantilever, which is slidably sleeved on the cross-sea bridge pier and located between the large cantilever and the floating cofferdam. Another part of the rigid support rod is used to fix the large cantilever and the short cantilever.

[0017] Based on the above technical solution, both the large cantilever and the short cantilever are frame-cross structures. The frame body in the middle of the frame-cross structure is used to fit the cross-sea pier. Its cross structure extends outward, and the length of the cross structure extending outward of the short cantilever is less than the length of the cross structure extending outward of the large cantilever. There are four power generation conversion devices, four rigid support rods and four flexible steel cables, which correspond to the four rods of the cross structure.

[0018] Based on the above technical solution, each rigid support rod has a V-shaped structure, and the bottom end of the V-shaped structure is fixedly supported by the end of the cross structure of the large cantilever; one side of the rigid support rod faces inward, and its end is connected to the end of the cross structure of the short cantilever; the other side of the rigid support rod faces outward, and its end is provided with an elbow hinge.

[0019] Based on the above technical solution, the cellular damper integrated module is assembled from four structural pieces.

[0020] The beneficial effects of the technical solution provided in this application include:

[0021] The protective power generation device of this application is uniquely designed by comprehensively considering the characteristics of adaptive impact energy dissipation and wave energy. Both the floating device and the honeycomb damper integrated module can achieve impact energy dissipation. The relative motion of the floating device and the cantilever device can also convert the potential energy of wave undulation into electrical energy, which has extremely high economic value.

[0022] In actual operation, the cellular damper integrated module can intelligently monitor and transmit monitoring data such as stress, strain and relative deformation in real time. It can intelligently evaluate the working mode and operation and maintenance status of the intelligent cellular damper integrated module, and protect the safety status of the cross-sea bridge pier in real time.

[0023] The cantilever device, composed of a large cantilever, a short cantilever, and a rigid support rod, has a certain displacement amplification effect. This unique cantilever device can significantly improve the conversion efficiency of wave undulation potential energy. When the actual rise of the floating device relative to the cantilever device is h, the actual elongation of the flexible steel cable is kh (k value is greater than 1), which can significantly improve the working efficiency of the power generation conversion device, thereby increasing the power of wave power generation within the effective area.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figures 1 to 5 As shown, this application discloses an embodiment of a protective power generation device for a cross-sea bridge pier. The protective power generation device includes a floating enclosure device 1, a power generation conversion device 3, a cantilever device, and a flexible steel cable 5. The floating enclosure device 1 can be floated and sleeved on the cross-sea bridge pier 13, which can not only eliminate wave energy, but also float up and down along the cross-sea bridge pier 13 when waves impact.

[0034] A power generation conversion device 3 is inserted through the floating enclosure device 1, and a power conversion wheel 7 is installed at the bottom of the power generation conversion device 3. The cantilever device is slidably sleeved on the cross-sea pier 13 and located below the floating enclosure device 1. Specifically, during wave impact, the cantilever device and the floating enclosure device 1 slide asynchronously relative to the cross-sea pier 13, resulting in vertical relative displacement.

[0035] One end of the flexible steel cable 5 is fixedly connected to an additional counterweight 8, and the other end is fixedly connected to a cantilever device. The additional counterweight 8 hangs circumferentially from the cantilever device, and the power conversion wheel 7 is wound around the middle of the flexible steel cable 5. Specifically, the additional counterweight 8 ensures that the flexible steel cable 5 is always in a stretched state, and the weight of the additional counterweight 8 can be increased or decreased according to actual needs.

[0036] When waves cause relative motion between the floating enclosure 1 and the cantilever device, the power conversion wheel 7 rotates under the action of the flexible steel cable 5, and the power generation conversion device 3 generates electricity. In actual operation, when waves impact, the cantilever device and the floating enclosure 1 undergo relative displacement, and the potential energy of the wave undulation is converted into the kinetic energy of the power conversion wheel 7. The kinetic energy of the power conversion wheel 7 is then converted into electrical energy through the power generation conversion device 3.

[0037] The protective power generation device of this application is uniquely designed by taking into account the characteristics of adaptive impact energy dissipation and collision prevention as well as wave energy. The floating device 1 can achieve collision prevention and energy dissipation, and the relative motion between the floating device 1 and the cantilever device can also convert the potential energy of wave undulation into electrical energy, which has extremely high economic value.

[0038] In one embodiment, the protective power generation device further includes a honeycomb damper integrated module 12, which is disposed at the center of the floating enclosure device 1. The floating enclosure device 1 is fitted onto the cross-sea bridge pier 13 via the honeycomb damper integrated module 12. Specifically, the honeycomb damper integrated module 12 is fitted onto the cross-sea bridge pier 13, and the floating enclosure device 1 is fitted onto the honeycomb damper integrated module 12.

[0039] The protective power generation device of this application can not only withstand impact energy dissipation through the floating enclosure device 1, but the honeycomb damper integrated module 12 can also withstand further impact energy dissipation. In actual operation, the honeycomb damper integrated module 12 can intelligently monitor and transmit stress, strain, and relative deformation data in real time, and can intelligently assess the working mode and maintenance status of the intelligent honeycomb damper integrated module, thus protecting the safety status of the cross-sea bridge pier in real time. The honeycomb damper integrated module 12 is assembled and installed around the cross-sea bridge pier 13, and it can undergo relative deformation to generate energy dissipation, reducing the effect of external impact loads.

[0040] In one embodiment, a rubber ring 2 is provided between the honeycomb damper integrated module 12 and the float device 1. The rubber ring 2 not only serves to separate the float device 1 and the honeycomb damper integrated module 12, but also makes the connection between the two tighter.

[0041] Specifically, one side of the rubber ring 2 is attached to the side of the float device 1, and the other side of the rubber ring 2 is attached to the honeycomb damper integrated module 12.

[0042] Furthermore, the floatation device 1 is circular with a rectangular hole in the center; the honeycomb damper integrated module 12 is rectangular and is installed in the rectangular hole of the floatation device 1.

[0043] In one embodiment, based on the above technical solution, the protective power generation device further includes a slip ring structure 11, which is located in the center of the cellular damper integrated module 12, and the cellular damper integrated module 12 is slidably sleeved on the cross-sea bridge pier 13 through the slip ring structure 11.

[0044] The protective power generation device of this application has a slip ring structure 11 that enables the combination of the honeycomb damper integrated module 12 and the floating device 1 to more quickly adapt to the up-and-down movement of the waves, so that the floating device 1 always floats on the sea surface, thereby improving the conversion efficiency of wave undulation potential energy.

[0045] like Figure 1As shown, in one embodiment, the cantilever device includes a large cantilever 9 and a rigid support rod 4. The large cantilever 9 is slidably fitted onto the cross-sea pier 13 and extends away from the cross-sea pier 13. A portion of the rigid support rod 4 is fixed to the large cantilever 9 and is arranged outwards; an elbow hinge 6 is provided at the outwardly extending end of the rigid support rod 4, and the middle part of the flexible steel cable 5 is also wound around the elbow hinge 6. The elbow hinge 6 allows the flexible steel cable 5 to turn without resistance.

[0046] Furthermore, the cantilever device also includes a short cantilever 10, which is slidably fitted onto the cross-sea pier 13 and is located between the large cantilever 9 and the floating cofferdam 1. Another part of the rigid support rod 4 is used to fix the large cantilever 9 and the short cantilever 10.

[0047] The protective power generation device of this application comprises a cantilever device consisting of a large cantilever 9, a short cantilever 10, and a rigid support rod 4. This uniquely structured cantilever device can significantly improve the conversion efficiency of wave undulation potential energy. Figure 6 As shown, specifically, when the potential energy of the wave undulations causes the floating device 1 to rise by an actual amount of h relative to the cantilever device, that is, when the flexible steel cable 5 changes from the first state to the second state, the actual elongation of the flexible steel cable 5 at this time is kh (the sum of the two thick solid lines in the figure). Specifically, the value of k is greater than 1, and the value of k mainly depends on the length of the rigid support rod 4 and the angle between the rigid support rod 4 and the flexible steel cable 5. The actual elongation of the flexible steel cable 5, kh, causes the flexible steel cable 5 to generate a rotational displacement of k times h in conjunction with the power conversion wheel 7, which can significantly improve the working efficiency of the power generation conversion device 3, thereby improving the energy conversion efficiency of wave power generation within the effective area.

[0048] Furthermore, both the large cantilever 9 and the short cantilever 10 are frame-cross structures. The frame-cross structure includes a middle frame body and an outer cross structure. The middle frame body of the frame-cross structure is used to mount the cross-sea pier 13. The frame body can move relative to the floating cofferdam 1 in the vertical direction. The cross structure of the frame body extends outward in the circumferential direction, and the length of the cross structure of the short cantilever 10 extending outward is less than the length of the cross structure of the large cantilever 9 extending outward.

[0049] Specifically, there are four of each of the power generation conversion device 3, rigid support rod 4, and flexible steel cable 5, which are respectively set up for the four rods of the cross structure.

[0050] In one embodiment, each rigid support rod 4 has a V-shaped structure, with the bottom end of the V-shape fixedly supported by the end of the cross structure of the large cantilever 9. One side of the rigid support rod 4 faces inward, and its end is connected to the end of the cross structure of the short cantilever 10. The large cantilever 9 and the short cantilever 10 are fixedly connected by one side of the rigid support rod 4, and both slide synchronously along the cross-sea pier 13, which can further enhance the stability of the protective power generation device. The other side of the rigid support rod 4 faces outward, and its end is provided with an elbow hinge 6 for supporting the flexible steel cable 5.

[0051] The protective power generation device of this application, under the action of waves, the floating device 1 adapts to the up and down movement of the waves. At this time, the rigid support rod 4, the flexible steel cable 5, the elbow hinge 6, the power conversion wheel 7, the additional counterweight 8, the large cantilever 9, and the short cantilever 10 form a motion amplification mechanism, which moves in coordination under the drive of the floating device 1.

[0052] When the floating device 1 and the cantilever device experience relative undulation displacement h, the motion amplification mechanism composed of the rigid support rod 4, flexible steel cable 5, elbow hinge 6, power conversion wheel 7, additional counterweight 8, large cantilever 9, and short cantilever 10 can significantly improve the working efficiency of the additional power generation conversion device 3, thereby increasing the power of wave power generation within the effective area.

[0053] like Figure 2 As shown, preferably, the cellular damper integrated module 12 is assembled from four structural pieces.
