[0015] Beneficial effects:

[0016] The present invention provides an assembled anti-collision device for bridge piers in water areas, which has the following significant beneficial effects:

[0017] 1. The modular assembly design allows each component to be prefabricated in the factory and quickly assembled on site through six movable connection structures into a regular hexagonal joint anti-collision structure, or directly connected to bridge piers and embankments. This can significantly shorten the on-site construction period, reduce water operation time, and minimize interference with water traffic. During later maintenance, damaged modules can be removed and replaced individually without the need for overall dismantling, significantly improving maintenance convenience.

[0018] 2. The six movable connection structures can achieve flexible connection at different angles through the multi-axis rotation design of the pitch axis, pitch link, pitch rocker arm and inner lining plate. They can adapt to regular bridge piers such as round and square ones, and can also fit special-shaped embankments or complex water structures through angle adjustment. They are highly versatile and solve the problem that traditional integral structures cannot adapt to diverse scenarios.

[0019] 3. The elliptical elastic tubes inside the annular tube body are cross-stacked to form a three-dimensional energy-absorbing network. During an impact, the elastic tubes absorb energy through the deformation of the elliptical cross-section and disperse the impact force in multiple directions. Compared with the traditional single structure, the energy absorption efficiency is improved.

[0020] 4. The rotating sleeve, cross and horizontal connecting rod in the internal support structure form a linkage mechanism. When the annular tube body is hit, the cross drives the horizontal connecting rod to rotate, and further absorbs energy through the compression of the reset spring. The reset spring is in a pre-compressed state and can automatically reset after a collision, so that the equipment has multiple anti-collision capabilities and extends its service life.

[0021] 5. Twelve detection airbags are evenly distributed outside the ring tube. They serve as flexible energy-absorbing elements. During a collision, they accurately monitor the impact position and intensity through changes in pressure inside the airbags. The data is transmitted to the monitoring system through built-in sensors to achieve real-time early warning of collision events. The detection airbags are equipped with pressure relief valves, which automatically release the internal gas when encountering an extremely strong impact, preventing the airbag from bursting and causing structural failure, thereby improving safety in extreme environments.

[0022] 6. The double floating ring tubes are respectively arranged on the inner and outer rings of the lower end surface of the ring tube body to evenly distribute the buoyancy and ensure that the equipment automatically rises and falls with changes in water level; the counterweight at the lower end of the anchor column enhances the anti-drifting ability and adapts to different water depth environments; the guide sleeve, vertical guide plate and horizontal guide plate on the anchor column constitute the water flow guide part. The axis of the rotatable horizontal guide plate is perpendicular to the direction of water flow, which effectively guides the water flow, reduces the impact load of water flow on the equipment, and improves stability in complex hydrodynamic environments.

[0040] The detailed connection means are well known in the art, and the working principle is as follows:

[0041] S1. Modular Assembly: Multiple ring tubes 1 are assembled into a regular hexagonal joint anti-collision network through six movable connection structures, or directly fixed around the perimeter of the bridge pier. Each ring tube 1 is buoyed by a floating ring tube 25, which, in conjunction with a counterweight 29 at the lower end of the anchor column 24, allows the device to float on the water surface and maintain vertical stability.

[0042] S2. Pre-tightening of the internal support structure: The return spring 9 is initially in a compressed state, and provides radial support force to the annular tube body 1 through the rotating sleeve 5, the cross 6 and the horizontal connecting rod 8, so that the entire structure has initial stiffness;

[0043] S3. When a ship or floating object strikes the device, the energy is dissipated gradually through the following levels:

[0044] After initial buffering by the movable connection structure, the impact force is transmitted to the detection airbag 3 at the outer end of the ring tube body 1. Its round-headed cylindrical inflatable structure deforms and absorbs the initial impact energy through gas compression. Twelve detection airbags 3 are evenly distributed at the outer end of the ring tube body 1, and the impact position can be accurately located through pressure changes.

[0045] The impact force is transmitted to the elliptical elastic tube 2 inside the ring tube body 1. The cross-stacked elliptical ring bodies disperse the single-point impact force into three-dimensional stress through elastic deformation in the long axis direction, effectively extending the action time and reducing the impact peak;

[0046] When the annular tube body 1 is deformed by impact, the cross 6 drives the horizontal connecting rod 8 to rotate around the inner support frame 7, forcing the rotating sleeve 5 to compress the return spring 9, converting the kinetic energy into the elastic potential energy of the spring; the linkage design of the four sets of horizontal connecting rods 8 disperses the impact force along the vertical diameter direction, avoiding local stress concentration;

[0047] If the impact energy exceeds the threshold, the pressure relief valve 20 on the detection airbag 3 automatically opens to release gas to prevent the detection airbag 3 from bursting. At the same time, the damping buffer part (damper 17, buffer spring 18) absorbs the remaining impact to avoid damage to the rigid structure.

[0048] S4. Automatic reset and multiple collision protection: After the collision, reset spring 9 releases its elastic potential energy, pushing rotating sleeve 5 and cross 6 back to their original shape, driving horizontal connecting rod 8 and ring tube body 1 to return to their original shape. The elastic material of elastic tube 2 also rebounds synchronously, allowing the device to quickly restore its protective capabilities and withstand multiple collisions.

[0049] S5. Intelligent monitoring and early warning:

[0050] The monitoring camera 21 collects video images in real time, and the auxiliary radar 22 scans and detects the target distance and speed. The data is transmitted wirelessly to the bridge management platform; the pressure sensor detecting the airbag 3 simultaneously uploads the impact intensity and position information;

[0051] When the system identifies an impact, it automatically triggers the warning light 23 to flash and sends an alarm signal to the management personnel; if the impact causes the equipment displacement to exceed the threshold, the water flow guide part (guide sleeve 26, horizontal guide plate 28) on the anchor column 24 reduces the impact by guiding the water flow and cooperates with the counterweight body 29 to maintain the stability of the equipment.

[0052] S6. Adaptability to water environment:

[0053] The dual floating ring tubes 25 automatically adjust the height of the equipment as the water level rises and falls, ensuring that the ring tube body 1 is always in an effective protective position; the multi-axis rotation design of the movable connection structure allows the equipment to swing slightly under the impact of water flow, avoiding structural damage caused by rigid connections;

[0054] The guide sleeve 26 drives the vertical guide plate 27 and the horizontal guide plate 28 to rotate with the water flow. The axis of the horizontal guide plate 28 is perpendicular to the direction of the water flow, which can disperse the impact force of the water flow and reduce the flow resistance, thereby improving the stability of the equipment in rapid or tidal environments.

[0055] In summary, the present invention adopts an assembled design, which is convenient for factory prefabrication, rapid on-site installation and later maintenance, shortens the construction period, and reduces the impact on water traffic; the six movable connection structures can be flexibly assembled to adapt to bridge piers or embankments of different shapes and sizes, and have strong versatility; the elliptical elastic tubes 2 are cross-stacked and combined with the internal support structure, which significantly improves the impact energy absorption and buffering effect, and effectively disperses the impact force; the reset spring 9 in the internal support structure is designed to automatically restore to its original state after a collision, achieving multiple anti-collision capabilities; the detection airbags 3 are distributed outside the ring body, can absorb energy and monitor the impact position and intensity in real time, and the pressure relief valve 20 prevents extreme damage; reduces bridge pier damage and maintenance costs, extends the life of the bridge, and saves social resources.
