[0027] The present invention discloses the following technical effects:

[0028] When water flows over a bridge pier, this invention guides the water flow through several flow-blocking plates. A horizontal roller and a circular guide rail are slidably connected, driving the anti-collision device to rotate around the pier in the circumferential direction. This effectively guides the water flow around the pier, reducing turbulence generated by the stationary pier and thus reducing the resistance brought by the water flow. It also reduces the wave effect generated by the water flow on the back of the pier, thereby reducing the vibration and pressure on the pier.

[0029] When subjected to impacts from small to medium-sized ships, this invention utilizes the rotational characteristics of horizontal and vertical rollers to deflect the impact direction instead of directly bearing the impact head-on, thereby effectively reducing the impact force on the bridge pier. Upon impact, the outermost layer of ultra-high-performance concrete directly bears the frontal impact. Its ultra-high strength and ultra-high toughness can effectively and evenly distribute the impact force to the corrugated plate and the first buffer layer. The corrugated plate and the first buffer layer simultaneously collapse and deform to absorb a large amount of impact energy. The remaining impact force is transferred to the second buffer layer, which compresses and deforms to absorb some energy. The remaining impact energy is transferred to the power generation unit through the horizontal rollers. At this point, the energy is unlikely to cause fatal damage to the bridge pier.

[0030] This invention can effectively reduce the water pressure on bridge piers and significantly reduce the risk of bridge piers being severely damaged by ship collisions. Compared with traditional bridge pier anti-collision devices for waterways, this invention has the advantages of multiple functions, outstanding energy consumption effect, stronger adaptability, and longer service life.

[0031] This invention can promptly adjust its protective height when the water level rises, demonstrating strong adaptability. During use, an appropriate size anti-collision device is selected based on the bridge pier dimensions and anti-collision requirements. First, horizontal rollers are installed on a circular guide rail, forming a single unit with the energy-generating and energy-absorbing units. Then, several assembled energy-generating units are aligned and spliced ​​around the bridge pier to form a circle. These units and energy-absorbing units are then installed on the bridge pier using fasteners. Finally, the wires extending from the energy-generating units are connected to the energy storage device. When the anti-collision device rotates under the impact of water flow, the relative motion between the first strong magnet group in the energy-absorbing unit and the second strong magnet group in the energy-generating unit generates electrical energy. This energy is then discharged through wires and stored in the energy storage device for nighttime street lighting, thereby reducing energy consumption. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Reference Figure 1-8 This invention provides an aluminum-UHPC composite bridge pier anti-collision device that also functions as a hydroelectric power generation device, comprising:

[0045] Several energy-absorbing units are arranged in a ring around the outer wall of the bridge pier; the energy-absorbing unit includes a first outer shell 1, and the inner cavity of the first outer shell 1 is provided with a first strong magnet group, a second buffer layer, a corrugated plate 4, a first buffer layer and ultra-high performance concrete 2 from the inside to the outside.

[0046] Several power generation units are arranged in a ring around the outer wall of the bridge pier, and the power generation units are located inside the energy absorption units; the power generation unit includes a second outer shell 14 and a second strong magnet group, the second strong magnet group is installed inside the second outer shell 14, and wires 9 are wound on the second strong magnet group;

[0047] The sliding unit includes several annular guide rails 8, several horizontal rollers 7, and several vertical rollers 10; the several horizontal rollers 7 are slidably connected along several annular guide rails 8, and the several vertical rollers 10 are in contact with the bridge pier.

[0048] The fixing assembly includes several flow-blocking plates 5-1 and several fasteners;

[0049] The second outer shell 14 has several annular guide rails 8 installed on its outer wall and several vertical rollers 10 installed on its inner wall; the first outer shell 1 has several flow deflectors 5-1 installed on its outer wall and several horizontal rollers 7 installed on its inner wall; adjacent first outer shells 1 and adjacent second outer shells 14 are detachably connected by fasteners; the second outer shell 14 is a single-layer cavity used to fix the second strong magnet assembly and the wires 9; both the first outer shell 1 and the second outer shell 14 are made of aluminum alloy.

[0050] In this embodiment, the annular guide rail 8 is an annular concave guide rail; the corrugated plate 4 is a corrugated aluminum alloy plate; and the wire 9 is a copper wire.

[0051] With this configuration, when water flows over the bridge pier, the present invention guides the water flow through several flow-blocking plates 5-1, and drives the anti-collision device to rotate circumferentially along the bridge pier through the sliding connection of the horizontal roller 7 and the annular guide rail 8, thereby effectively guiding the water flow around the bridge pier, reducing the turbulence generated by the stationary bridge pier, thereby reducing the resistance brought by the water flow, and also reducing the wave effect generated by the water flow on the back of the bridge pier, thereby reducing the vibration and pressure on the bridge pier;

[0052] When subjected to impacts from small to medium-sized ships, this invention utilizes the rotational characteristics of the horizontal rollers 7 and vertical rollers 10 to deflect the impact direction instead of directly bearing the frontal impact, thereby effectively reducing the impact force on the bridge pier. Upon impact, the outermost layer of ultra-high performance concrete 2 directly bears the frontal impact. Its ultra-high strength and ultra-high toughness can effectively and evenly distribute the impact force to the corrugated plate 4 and the first buffer layer. The corrugated plate 4 and the first buffer layer simultaneously collapse and deform to absorb a large amount of impact energy. The remaining impact force is transferred to the second buffer layer, which compresses and deforms to absorb some energy. The remaining impact energy is transferred to the power generation unit through the horizontal rollers. At this point, the energy is unlikely to cause fatal damage to the bridge pier.

[0053] This invention can effectively reduce the water pressure on bridge piers and significantly reduce the risk of bridge piers being severely damaged by ship collisions. Compared with traditional bridge pier anti-collision devices for waterways, this invention has the advantages of multiple functions, outstanding energy consumption effect, stronger adaptability, and longer service life.

[0054] This invention can promptly adjust its protective height when the water level rises, making it highly adaptable. During use, a suitable anti-collision device of appropriate size is selected based on the pier dimensions and anti-collision requirements. First, the horizontal roller 7 is installed on the annular guide rail, making the power generation unit and energy absorption unit a single unit. Then, several assembled power generation units are spliced ​​and aligned around the pier to form a circle. The power generation units and energy absorption units are then fastened onto the pier using fastening components. The wires extending from the power generation unit are then connected to the energy storage device (not shown in the figure). When the anti-collision device rotates under the impact of water flow, the first strong magnet group in the energy absorption unit and the second strong magnet group in the power generation unit move relative to each other, generating electrical energy. This energy is then discharged through the wires and stored in the energy storage device for nighttime street lighting, reducing energy consumption.

[0055] The device of the present invention is simple to assemble, has multiple functions, and has outstanding energy absorption effect. By using this device to protect bridge piers, it can not only greatly improve the anti-collision capability of bridge piers, but also make reasonable and effective use of water resources.

[0056] In a further optimized design, the inner cavity of the first outer shell 1 is divided into four cavities by three partition plates, which are arranged sequentially from the inside to the outside of the inner cavity of the first outer shell 1. The three partition plates are welded into the inner cavity of the first outer shell 1 using laser welding, so that the four cavities are independent and sealed.

[0057] In this embodiment, the partition plate, the first outer shell 1, and the second outer shell 14 are all made of aluminum alloy.

[0058] After the first outer shell 1 is poured with ultra-high performance concrete 2 and assembled with the first buffer layer, corrugated plate 4, second buffer layer, and first strong magnet assembly, the four cavities of the first outer shell 1 are welded into an independent sealed whole using aluminum alloy partition plates of appropriate size.

[0059] The first strong magnet assembly, the second buffer layer, the corrugated plate 4, the first buffer layer and the ultra-high performance concrete 2 are arranged in four cavities from the inside out, and the corrugated plate 4 and the first buffer layer are installed in the same cavity.

[0066] Several second artificial strong magnets 11-2 are installed at equal intervals inside the second outer casing 14. Wires 9 are wound around the second artificial strong magnets 11-2. The wires 9 are located inside the cavity of the second outer casing 14, with both ends extending from the top of the second outer casing 14. The gap between the wires 9 and the second outer casing 14 is sealed with resin. The wires 9 of two adjacent power generation units are connected by a waterproof connector 12. The waterproof connector 12 includes a male connector 12-1 and a female connector 12-2 that is compatible with the male connector 12-1. Electrical energy is transmitted through the compatible male connector 12-1 and female connector 12-2.

[0067] The second outer shell 14 is divided into several vertical cavities of the same size. Then, the second artificial strong magnets 11-2, which are wrapped with wires 9, are embedded in the vertical cavities at intervals. The top of the vertical cavities is welded and sealed using an aluminum alloy plate of appropriate size.

[0068] The design was further optimized so that the lengths of the first and second baffles are the same as the height of the first outer shell 1.

[0069] The width of the first baffle plate and the width of the second baffle plate are both not less than 15cm, and the thickness of the first baffle plate and the thickness of the second baffle plate are both not less than 0.4cm.

[0070] The angle between the first baffle plate, the second baffle plate and the tangent of the outer wall of the first outer shell 1 is 0° to 15°.
