Description

Technical Field

[0001] The invention relates to the field of bridge construction, and in particular to the technical field of a composite bridge anti-collision system. Background Art

[0002] In the field of bridge safety protection, although the traditional passive steel pontoon anti-collision structure can absorb collision energy to a certain extent and protect the bridge piers from direct damage caused by ship collisions, its own limitations cannot be ignored. Steel pontoons are prone to permanent deformation after being hit, and repair is complex and costly; the fragility of the connection parts is a major hidden danger to the anti-collision performance. Once it is hit by a precise impact, the protection ability of the overall structure will be greatly reduced. In addition, the steel pontoon anti-collision device also poses a potential threat to the colliding ship, which may cause damage to the ship or even casualties.

[0003] Therefore, some bridge anti-collision systems are currently equipped with active systems, mainly radar, video surveillance, software platforms, sound and light devices, etc. When a ship deviates from the scheduled route, the active system will sound an alarm to remind the ship to correct the deviation in time. However, the arrangement of electrical devices for the active system on each pier also increases the cost of the entire bridge protection.

[0004] In view of this, there is an urgent need for an innovative anti-collision system that integrates active protection and passive protection to make up for the shortcomings of traditional protection solutions. Summary of the invention

[0005] In view of the above-mentioned problems, the present invention proposes a composite bridge anti-collision system to address the deficiencies of the prior art, aiming to provide anti-collision measures that combine active and passive systems and can reduce damage to passive systems and ships while avoiding huge construction and maintenance costs.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A composite bridge anti-collision system comprises a steel pontoon arranged in a ring around a bridge pier, a guide rail arranged in a ring around the outer periphery of the steel pontoon, a guide rail bracket connecting the guide rail and the steel pontoon, a rotating barrel assembly arranged on the guide rail and rotatable, and an active system capable of sounding an alarm to remind ships;

[0008] The steel pontoon comprises a box assembly arranged in sections and a connecting flange connecting the box assembly;

[0009] The rotary barrel assembly is driven by water flow to rotate and can generate electricity autonomously, and the active system relies on the autonomous power generation of the rotary barrel assembly to maintain operation.

[0010] Compared with the existing technology, this case adds a rotating barrel assembly on the periphery of the steel pontoon set around the bridge pier. By utilizing the rotatable characteristics of the rotating barrel assembly, the direction of the ship can be corrected when a ship collides, and the ship can be restored to the normal navigation track to avoid impact rebound and protect the ship and the bridge. At the same time, the rotating barrel assembly is driven by the water flow to rotate and generate electricity autonomously to provide power supply to the active system, so that the entire anti-collision system can achieve autonomous operation without increasing too much cost.

[0011] In some embodiments, the guide rail includes an upper guide rail and a lower guide rail which are spaced apart from each other, and the rotary barrel assembly is disposed between the upper guide rail and the lower guide rail.

[0012] In some embodiments, the guide rail is an L-shaped rail with two backrests and a gap, and the rotary barrel assembly is installed in the gap of the L-shaped rail.

[0013] In some embodiments, the guide rail bracket is provided with a slider that can slide on the guide rail bracket, and the guide rail is connected to the guide rail bracket via the slider.

[0014] In some embodiments, the guide rail bracket is provided at at least one connecting flange, and a safety airbag is provided between the outer side of the connecting flange and the sliding block, which can protect the connecting flange and prevent it from being damaged and causing the box assembly to fall apart.

[0015] In a preferred embodiment, the safety airbag is arranged on the outer sides corresponding to the connecting flanges on both sides of the steel buoyancy tank in the water flow direction.

[0016] In a preferred embodiment, a protective baffle is provided between the slider and the airbag, which serves as a threshold for triggering the airbag.

[0017] In some embodiments, a seismic isolation pad is provided between the steel pontoon and the bridge pier.

[0018] In some embodiments, the active system is a radar and / or video surveillance and / or a software platform and / or an acoustic and optical device. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The features of the present invention and other related features are further described in detail below through embodiments to facilitate understanding by those skilled in the art:

[0026] Please refer to Figure 1 The present invention discloses a composite bridge anti-collision system, comprising a steel pontoon 100 arranged in a ring around a bridge pier 1 and a guide rail 200 arranged in a ring around the outer periphery of the steel pontoon 100. The bridge pier 1 is arranged on the upper part of the pedestal 2, and each pedestal 2 may be provided with one or more bridge piers 1. The steel pontoon 100 takes the pedestal 2 as a unit and surrounds one or more bridge piers 1. The guide rail 200 and the steel pontoon 100 are connected by a guide rail bracket 210. A plurality of guide rail brackets 210 may be provided as required. In this embodiment, two guide rail brackets 210 are provided on each surface. The system of the present invention also includes a rotatable rotary barrel assembly 300 provided on the guide rail 200. In this way, on the basis of the steel pontoon 100 arranged around the bridge pier 1, a rotary barrel assembly 300 is additionally provided on its outer periphery. By utilizing the rotatable characteristics of the rotary barrel assembly 300, when a ship collides, the direction of the ship can be corrected and restored to the normal navigation track, so as to avoid impact rebound and protect the ship and the bridge.

[0027] Please refer to Figure 2 and Figure 3 Specifically, the steel pontoon 100 includes a box assembly 110 arranged in sections and a connecting flange 120 connecting the box assembly 110. In a preferred case, a seismic isolation pad 400 is provided between the inner side of the steel pontoon 100 and the bridge pier 1. Specifically, it can be a rubber pad, a lead rubber pad, a sliding pad or other types of shock absorbing devices.

[0028] Please refer to Figure 4 Specifically, the guide rail 200 includes an upper guide rail 201 and a lower guide rail 202 spaced apart from each other, and the rotary barrel assembly 300 is disposed between the upper guide rail 201 and the lower guide rail 202. Figure 5, the guide rail 100 is an L-shaped rail 220 for the backrest, and there will be a gap between the L-shaped rails 220. The rotary barrel assembly 300 passes through the above gap and is installed in the L-shaped rail gap. Specifically, the rotary barrel assembly 300 includes a rotating shaft 301 passing through the gap between the above L-shaped rails 220, and the rotating shaft 301 is fixed to the L-shaped rail 220 by bolt connection. The rotating shaft 301 is inserted into the rotary barrel 302 that can rotate around the rotating shaft 301. Here, the rotary barrel 302 is located between the upper guide rail 201 and the lower guide rail 202, which can limit its upper and lower positions, and can also be driven to rotate by water flow.

[0029] The material of the rotary barrel 302 is a composite material, which has a certain strength and can withstand impact force. In addition, it is also a flexible energy-absorbing material, so it can buffer the impact force. Specifically, a composite material composed of a composite material of EVA (ethylene-vinyl acetate copolymer) and polyurethane can be used. This material combination is very elastic and can effectively absorb impact energy and reduce the impact force during collision. At the same time, it has good wear resistance and can withstand multiple impacts without being easily damaged. At the same time, it has strong restoring power. Even if it suffers a serious impact, the rotary barrel made of this composite material can quickly return to its original shape, maintain its protective function, and reduce the frequency of maintenance and replacement. In addition to excellent mechanical properties, this material also has good weather resistance, can resist the influence of natural environment such as ultraviolet radiation and rain erosion, and prolong its service life. In specific applications, the appearance of the rotary barrel 302 can also be designed to be very eye-catching to enhance the visual warning effect.

[0030] In some embodiments, as described above, the buffering is performed by the rotary barrel assembly 300. In order to further enhance the buffering effect of the integral rotary barrel bridge anti-collision device, in some embodiments, a slider 211 is provided on the guide rail bracket 210. The slider 211 can slide on the guide rail bracket 210, and the guide rail 200 is connected to the guide rail bracket 210 through the slider 211. In this way, when impacted, the integral guide rail 200 can also have a buffering effect, and subsequent repair is also convenient.

[0031] Furthermore, when the impact force of the ship is large enough to break through the guide rail 200 and the rotary barrel assembly 300, the steel pontoon 100 needs to bear the impact force. The actual weak link is the connecting flange 120 between the box assemblies 110. The damage of the connecting flange 120 will easily cause the box assemblies to break apart, which will affect the buffering effect of the steel pontoon 100. In this regard, as a protection measure for the connecting flange 120, a guide rail bracket 210 is provided at the connecting flange 120, and a safety airbag 500 is provided between the connecting flange 120 and the slider 211 of the guide rail bracket 210. When the ship breaks through the guide rail 200 and the rotary barrel assembly 300, the connecting flange can be protected to prevent the box assembly 110 from falling apart due to the damage.

[0032] Specifically, the connecting flanges 120 on the corresponding sides of the water flow direction can be selected. For example, in the embodiment, the four connecting flanges 120 on both sides can be set with the guide rail bracket 210. Of course, the connecting flange 120 that is easily impacted in one of the commonly used waterways can also be selected. Here, one of the main reasons for setting the slider 211 and the airbag 500 in this case is also because of the maintenance cost. The bridge is a fixed building that is continuously used, so it is also necessary to consider its municipal maintenance cost. It is a very important link. Therefore, in addition to the maintenance of the protective steel pontoon 100, the maintenance cost of the airbag 500 also needs to be considered. In order to prevent the airbag 500 from being activated prematurely, a protective baffle 212 that acts as a trigger threshold can be set between the slider 211 and the airbag 500. When the impact of the ship is not large enough, the protective baffle 212 is subjected to force. When a certain force is reached, the protective baffle 212 is broken and the airbag 500 is activated. As a damping structure with a threshold effect, pins, cam mechanisms, spring compression, etc. can also be used.

[0033] A composite bridge anti-collision system in this case also includes an active system that can sound an alarm to alert ships. The active system can be selected from radar, video surveillance, software platform, sound and light device, and other sensors. However, these active defense systems require electric drive, and the arrangement of electric devices for the supporting active system on each pier also increases the cost of the entire bridge protection. For this reason, the rotary barrel assembly 300 in this case is driven by the water flow to rotate and can generate electricity autonomously. The conversion of rotational kinetic energy into electrical energy is a common means in the industry, and its implementation scheme will not be repeated here. The active system in this case relies on the autonomous power generation of the rotary barrel assembly 300 to maintain operation.

[0034] In general, in this case, a rotary barrel assembly 300 is arranged on the periphery of the steel pontoon 100 to protect the ship and the steel pontoon 100 when it is impacted by a ship. At the same time, the guide rail bracket 210 used to fix the rotary barrel assembly 300 is used as a trigger mechanism to activate the airbag 500 arranged on the outside of the connecting flange 120, which can not only prevent the box assembly 110 from falling apart due to damage to the connecting flange 120, but also save maintenance costs. Furthermore, the self-generation of the rotary barrel assembly 300 can be used to supply power to the active system, so that a composite bridge anti-collision system in this case can cooperate with each other to achieve step-by-step protection, minimize collision hazards and losses when a collision occurs, and the maintenance cost of the system in this case.

[0035] As mentioned above, this case protects a composite bridge anti-collision system, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
