Description

Technical Field

[0001] This invention relates to the technical field of anti-collision for bridge piers in biomass power plants, and particularly to a composite prefabricated anti-collision buffer device for the water diversion hub bridge piers of biomass power plants. Background Technology

[0002] Piers at water diversion hubs of biomass power plants and piers for cross-water structures supporting new energy industries (such as navigation piers for photovoltaic-hydraulic complementary projects and traffic piers for tidal power plants) serve as core structures of energy and transportation integration infrastructure, providing long-term support for the production, transportation, and supporting infrastructure of the new energy industry. These piers not only facilitate navigation but are also directly linked to critical aspects of the biomass and other new energy industries, including raw material transportation (such as biomass fuel transport vessels) and equipment maintenance (such as power plant repair vessels). Their collision safety directly impacts the production continuity and operational stability of the new energy industry.

[0003] Existing bridge pier anti-collision devices have significant limitations: traditional rigid devices rely on a single steel material to resist impacts, resulting in weak energy absorption capacity. The impact force can be directly transmitted to the main body of the bridge pier in new energy construction projects, leading to pier cracking, structural deformation, and ultimately disrupting the water transport and maintenance channels for biomass power plants and other new energy facilities. Simple buffer devices often use a single material for filling, resulting in a single form of energy absorption and insufficient structural stability. They are prone to collapse and failure after impact, making them unsuitable for the complex impact conditions of vessels in waters related to the new energy industry (such as heavy equipment transport vessels and high-frequency maintenance vessels). At the same time, the installation and subsequent maintenance of these devices require complete disassembly, which is complex and time-consuming. For biomass energy and other new energy construction projects that need to continuously ensure production and operation, this seriously affects the efficiency of industrial operations and cannot meet the actual needs of efficient protection and low-cost operation and maintenance.

[0004] How to design a prefabricated structure that combines collision protection and buffering functions, while improving energy absorption and structural stability, simplifies installation and maintenance processes, and precisely adapts to the special protection needs of bridge piers in biomass power generation construction projects and new energy construction projects, has become an urgent problem to be solved in the field of collision protection technology for new energy supporting infrastructure.

[0033] Example 1

[0034] Reference Figures 1-4This first embodiment of the invention provides a composite prefabricated anti-collision buffer device for the piers of a biomass power plant water diversion hub, including an anti-collision component 100 and a buffer component 200. The two work together to achieve multi-level attenuation, precise guidance and efficient energy absorption of the impact force of ships, specifically solving the problems of single energy absorption and poor buffering effect of traditional anti-collision devices. At the same time, it takes into account the convenience of installation and structural stability, greatly improving the impact resistance of bridge piers, extending the service life of bridges, and adapting to the protection needs of complex impact angles of ships of different tonnages.

[0035] Furthermore, in this embodiment, the anti-collision component 100 is the core anti-collision unit of the device, realizing the initial transmission and decomposition of the impact force. The anti-collision component 100 includes an anti-collision plate 101 installed on the pier of the water diversion hub, an anti-collision component 102 installed on the anti-collision plate 101, and an auxiliary buffer component 103 installed on the anti-collision component 102. The anti-collision plate 101 covers the entire bottom of the bridge and serves as the main structure of the entire anti-collision device.

[0036] Furthermore, in this embodiment, the anti-collision plate 101 includes a first anti-collision inner plate 1011 disposed at the bottom of the bridge, a plurality of anti-collision cavities 1012 on the first anti-collision inner plate 1011, and an abutment buffer plate 1013 disposed on the anti-collision cavity 1012. The first anti-collision inner plate 1011 is disposed along the shape of the bottom of the bridge. The first anti-collision inner plate 1011 adopts a splicing design, which facilitates the operator to install and disassemble it. At the same time, a plurality of horizontal and vertical steel plates are disposed on the first anti-collision inner plate 1011, and the area formed between the plurality of horizontal and vertical steel plates is the anti-collision cavity 1012.

[0037] The abutment buffer plate 1013 corresponds to the anti-collision cavity 1012. Meanwhile, the anti-collision component 102 is disposed within the anti-collision cavity 1012. A pier connector is also disposed inside the first inner anti-collision plate 1011, which can be stably installed on the pier. The abutment buffer plate 1013 corresponds to the mounting cavity 2013 of the buffer assembly 200, and the anti-collision component 102 is disposed within the anti-collision cavity 1012.

[0038] The first anti-collision inner plate 1011 is firmly connected to the bridge pier through the bridge pier connector. Each first anti-collision inner plate 1011 is integrally formed from high-strength alloy steel plate with anti-corrosion coating on the surface, which can withstand the erosion of complex marine or terrestrial environments. The array design of the anti-collision cavity 1012 disperses the concentrated impact force to multiple cavities, avoiding plate breakage caused by local stress concentration. The abutment buffer plate 1013 is made of elastic steel. When impacted, it first undergoes elastic deformation to initially dissipate the impact kinetic energy, and at the same time guides the impact force to be transmitted to the anti-collision component 102 to avoid force deflection.

[0039] Furthermore, the present invention also includes a buffer component 200, which is a front-end energy absorption unit of the device to achieve initial interception and attenuation of the impact force.

[0040] In this embodiment, the buffer assembly 200 includes a plurality of first guardrails 201 disposed on the anti-collision plate 101, a plurality of buffer cylinders 202 disposed on the first guardrails 201, and a plurality of buffer fillers 203 disposed in the buffer cylinders 202. The first guardrails 201 are disposed on the outside of the anti-collision plate 101 and serve as the main structure subjected to impact. The first guardrails 201 cooperate with the structure of the horizontal and vertical steel plates on the anti-collision plate 101 to enhance the impact resistance of the entire anti-collision device, while the buffer cylinders 202 are used to absorb the kinetic energy during impact.

[0041] Furthermore, in this embodiment, the first guardrail 201 includes a plurality of longitudinally arranged longitudinal anti-collision beams 2011 and transverse anti-collision beams 2012 connecting the longitudinal anti-collision beams 2011. The transverse anti-collision beams 2012 surround to form an anti-collision ring. An installation cavity 2013 is formed between the anti-collision ring and the longitudinal anti-collision beams 2011, and the installation cavity 2013 corresponds to the anti-collision cavity 1012.

[0042] Preferably, the longitudinal anti-collision beam 2011 and the transverse anti-collision beam 2012 are welded from high-strength steel pipes to form a crisscrossing three-dimensional protective structure. The anti-collision ring can guide the impacting object to slide along the annular surface. When impacted, it can change the impact direction to a certain extent, avoid head-on collision, and reduce instantaneous impact force. In addition, the mounting cavity 2013 provides a stable mounting base for the buffer cylinder 202, ensuring that the buffer component 200 and the anti-collision component 100 work together to bear the force, thereby enhancing the impact resistance of the entire anti-collision device.

[0043] Furthermore, in this embodiment, a plurality of buffer cylinders 202 are installed in the mounting cavity 2013. The buffer cylinders 202 are arranged laterally, and there are multiple of them arranged in an array in the mounting cavity 2013. In this embodiment, the buffer cylinder 202 includes a plurality of annular cylinders 2021 disposed on the first guardrail 201 and protruding rings 2022 disposed outside the annular cylinders 2021. The buffer filler 203 includes a filler bag 2031 disposed in the annular cylinders 2021, glass fiber reinforced polyurethane foam disposed in the filler bag 2031, and energy-absorbing element 2032 disposed in the filler bag 2031.

[0044] Preferably, the annular cylinder 2021 is a hollow cylindrical tube, with protruding rings 2022 protruding outwards and arranged in an array at equal intervals on the side wall of the annular cylinder 2021. The axial direction of the annular cylinder 2021 faces outwards, and steel plates are arranged on the axial direction surfaces of several annular cylinders 2021. The steel plates first receive the impact force. The glass fiber reinforced polyurethane foam filled inside has both elasticity and rigidity, high compression ratio, and high energy absorption density, and has a very high energy absorption efficiency compared with ordinary foam.

[0045] Preferably, in this embodiment, the energy-absorbing component 2032 includes several flexible metals disposed between the glass fiber reinforced polyurethane foam and the inner wall of the annular cylinder 2021. The flexible metals further absorb residual energy through metal plastic deformation, forming a buffer form of foam buffer and flexible metal damping energy absorption, further reducing the impact force and ensuring that the initial impact force can be rapidly attenuated. The buffer cylinder 202 adopts a detachable design and can be replaced individually after the impact without the need for an overall disassembly device.

[0046] Operation process: The device is fixed at a preset position at the bottom of the bridge using the pier connector of the first anti-collision inner plate 1011 to ensure a firm connection; the buffer cylinder 202 is embedded into the mounting cavity 2013 of the first guardrail 201, and the filling bag 2031 is inserted into the annular cylinder 2021 to complete the assembly of the buffer component 200; the flexibility of the rotation rod 1024 and output rod 1025 of the anti-collision component 102 is checked to ensure that the extension rod 306 and the auxiliary buffer component 103 cooperate smoothly.

[0047] Initial impact buffering: When a ship or vehicle collides with the device, it first contacts the anti-collision ring of the first guardrail 201. The annular surface guides the impacting object to slide and change the impact direction. The protruding ring 2022 of the buffer cylinder 202 disperses the pressure. The glass fiber reinforced polyurethane foam in the filling bag 2031 is compressed and deformed. The energy-absorbing component 2032 undergoes plastic deformation simultaneously, absorbing and reducing the impact kinetic energy.

[0048] Example 2

[0049] Reference Figures 5-8This embodiment also discloses that: In this embodiment, the anti-collision component 102 includes a shock-absorbing cylinder 1021 disposed within the anti-collision cavity 1012, an intermediate column 1022 disposed within the shock-absorbing cylinder 1021, a plurality of connecting blocks 1023 disposed on the outer peripheral wall of the intermediate column 1022, a plurality of rotating rods 1024 rotatably connected to the connecting blocks 1023, and an output rod 1025 disposed on the rotating rods 1024. The shock-absorbing cylinder 1021 is disposed along a direction perpendicular to the surface of the first anti-collision inner plate 1011, and extends towards... Extending outwards and connected to the abutment buffer plate 1013, the intermediate column 1022 is set inside the shock absorber 1021. There are four rotating rods 1024, which are arranged in pairs. The rotating rods 1024 in each pair are arranged parallel to each other. The output rods 1025 are horizontally connected to the two rotating rods 1024. The two output rods 1025 are located at the upper and lower positions of the shock absorber 1021, respectively, and are symmetrical to each other. At the same time, a groove is opened on the shock absorber 1021 for accommodating the connecting block 1023 and the rotating rods 1024.

[0050] Furthermore, a receiving block 1026 is provided at the end of the intermediate column 1022. The receiving block 1026 has a large overall size and is used to connect with the abutment buffer plate 1013, and can withstand a large area of ​​impact.

[0051] Furthermore, a bracket 300 is provided at the rear end of the shock absorber 1021, and the sliding groove 301 on the bracket 300 is slidably connected to the slider 302 at the rear end of the output rod 1025; an installation cylinder 303 is provided in the anti-collision cavity 1012, and an extension rod 306 is slidably connected in the drive groove 304 on the inner wall of the installation cylinder 303; a first inclined surface 307 is provided on the insertion rod 305 on the output rod 1025, and a second inclined surface 308 is provided at the end of the extension rod 306, and the two cooperate to drive the extension of the extension rod 306.

[0052] Preferably, the impact force is transmitted to the receiving block 1026 through the abutment buffer plate 1013, pushing the intermediate column 1022 into the shock absorber 1021. The connecting block 1023 drives the rotating rod 1024 to rotate, thereby causing the two output rods 1025 to move away from the shock absorber 1021, and then push the insertion rod 305. The first inclined surface 307 of the insertion rod 305 cooperates with the second inclined surface 308 of the extension rod 306. The first inclined surface 307 of the insertion rod 305 squeezes the second inclined surface 308 of the extension rod 306, converting the longitudinal impact force into the lateral thrust of the extension rod 306, pushing the extension rod 306 outward.

[0053] Preferably, the auxiliary buffer component 103 is disposed at the cavity opening of the anti-collision cavity 1012. In this embodiment, the auxiliary buffer component 103 includes a buffer plate 1031 at the end of the extension rod 306, an auxiliary buffer box 1032 disposed on the anti-collision cavity 1012, buffer contents disposed in the auxiliary buffer box 1032, and four auxiliary buffer boxes 1033 disposed on the auxiliary buffer box 1032.

[0054] Preferably, four buffer sub-boxes 1033 are provided, and the four buffer sub-boxes 1033 are stacked in a matrix array. When viewed from a top-down perspective, two buffer sub-boxes 1033 are located on the left side and two buffer sub-boxes 1033 are located on the right side. The two buffer sub-boxes 1033 on the left side are hinged together by a first hinge rod 1034. The buffer sub-box 1033 closest to the auxiliary buffer box 1032 is connected to the box by a third hinge rod 1036. The buffer sub-box 1033 furthest from the auxiliary buffer box 1032 is provided with a second hinge rod 1035. The middle section of the second hinge rod 1035 is hinged to the buffer sub-box 1033 closest to the auxiliary buffer box 1032. The first hinge rod 1034, the second hinge rod 1035 and the third hinge rod 1036 are parallel to each other. The other set of two buffer sub-boxes 1033 are also provided with the above structure, and the arrangement is the same as the above structure.

[0055] Preferably, a mating gear 1037 is provided at the end of the third hinge rod 1036, a rack 1038 is provided on the auxiliary buffer box 1032, the rack 1038 is connected to the buffer plate 1031, and a buffer pad is provided on the buffer sub-box 1033.

[0056] Operation process: The extension rod 306 pushes the buffer plate 1031, which drives the rack 1038 to move. Through the cooperation of the gear 1037, the third hinge rod 1036 is driven to rotate, which in turn drives the second hinge rod 1035 and the first hinge rod 1034 to synchronously contract or expand the four buffer sub-boxes 1033, thereby expanding the buffer area. The buffer contents absorb the impact kinetic energy through compression and deformation. The buffer pad is made of highly elastic rubber material to further attenuate the residual impact force.

[0057] If the impact is strong enough to break through the front buffer cylinder 202, the residual impact force is transmitted to the abutment buffer plate 1013 of the anti-collision plate 101. After the elastic deformation of the abutment buffer plate 1013 dissipates some of the energy, it pushes the receiving block 1026 and the middle column 1022 to move, thereby causing the two output rods 1025 to move away from the shock absorber cylinder 1021. Then, it pushes the insert rod 305. The first inclined surface 307 of the insert rod 305 and the second inclined surface 308 of the extension rod 306 cooperate. The first inclined surface 307 of the insert rod 305 squeezes the second inclined surface 308 of the extension rod 306, thus pushing the longitudinal impact... The impact force is converted into a lateral thrust of the extension rod 306, which pushes the extension rod 306 outward. This then drives the buffer plate 1031 to move, causing the rack 1038 to slide and drive the mating gear 1037 to rotate. This causes the four buffer sub-boxes 1033 to unfold outward, increasing the force-bearing area. The forward movement of the buffer sub-boxes 1033 pushes the hull outward, thus offsetting part of the impact force. At the same time, the outwardly unfolded buffer sub-boxes 1033 can also withstand the next three or four impacts, absorbing the remaining impact energy. Ultimately, the impact force transmitted to the pier is attenuated to a safe range, preventing damage to the pier.
