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

[0002] The safety protection of road and bridge piers has always been a concern. The design and construction of pier structures are major topics that engineering and technical designers are committed to studying, and are the key to ensuring the safety of roads and bridges. According to research, the current pier branches are equipped with anti-collision devices, which have a certain protection effect on road and bridge protection, but there are still certain defects and hidden dangers, and the comprehensive protection effect of "active prevention and passive anti-collision" has not yet been achieved. Especially for the piers of roads and bridges that have been completed, it is often impossible to add relevant anti-collision devices or structures on the basis of existing structures, especially now that the tonnage of ships is getting larger and larger, and the existing piers can no longer meet today's anti-collision requirements. In response to this phenomenon, if a pier safety anti-collision system is designed, it can be applied and installed on existing or newly constructed piers, which can greatly improve the safety of piers and reduce the risk of collapse of roads and bridges due to passive collisions.

[0008] Furthermore, the top surface of the support seat is formed with an annular extension and is used to partially support and accommodate a support ring groove that moves toward the bearing group.

DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0022] See attached Figure 1-3 As shown, in this embodiment, a pier anti-collision buffer protection system includes an early warning monitoring device and an energy absorbing buffer device fixedly mounted on the periphery of the pier, wherein the energy absorbing buffer device is used to be fixedly mounted on the periphery of the pier to achieve a buffer protection effect, specifically including a fixed column hoop 1 fixedly mounted on the periphery of the pier, an energy release buffer layer 2 and a contact surface layer 4, the fixed column hoop 1 is made of high-strength steel material as a fixed sleeve on the pier, and the fixed column hoop 1 here has sufficient rigidity to support the remaining components and rigidly protect the pier.

[0023] In this embodiment, the energy release buffer layer 2 is coaxially arranged on the periphery of the fixed column hoop 1, and at least one group of rolling components 3 is arranged between the energy release buffer layer 2 and the fixed column hoop 1 so that the energy release buffer layer 2 can rotate around the fixed column hoop 1 with the help of the rolling components 3, wherein at least two groups of rolling components 3 arranged along the axial direction are arranged between the energy release buffer layer 2 and the fixed column hoop 1, and the specific number of rolling components 3 used is determined by the height of the fixed column hoop 1 and the energy release buffer layer 2, that is: when the height of the fixed column hoop 1 and the energy release buffer layer 2 is longer, the number of rolling components 3 is correspondingly more. Secondly, each group of the rolling components 3 includes a support seat 31 with a fixed ring arranged on the outer circumference of the fixed column hoop 1, a rotating seat 33 with a fixed ring arranged on the inner circumference of the energy release buffer layer 2, and a plurality of moving bearing groups 32 rollingly clamped between the support seat 31 and the rotating seat 33, thereby, the rolling action of the moving bearing group 32 is used to realize the rotational connection between the support seat 31 and the rotating seat 33, so that the energy release buffer layer 2 can rotate when subjected to external force.

[0024] In this embodiment, the top surface of the support seat 31 is formed with a supporting annular groove 311 which is annularly extended and used to partially support and accommodate the bearing group 32. The bottom surface of the rotating seat 33 is formed with a supporting annular groove 321 which is annularly extended and used to partially press and accommodate the bearing group 32. The supporting annular groove 311 is aligned with the rotating annular groove 321. The supporting annular groove 311 and the rotating annular groove 321 are used here to simultaneously limit and guide the bearing group 32, thereby ensuring that the rotation of the rotating seat 33 and the energy release buffer layer 2 relative to the support seat 31 is more stable and reliable. In particular, when the external force applied to the energy release buffer layer 2 is transmitted to the rotating seat 33, problems such as separation of the rotating seat 33 from the support seat 31 and / or falling off of the bearing group 32 will not occur. In addition, a downwardly extending limiting portion is integrally formed at the inner end of the rotating seat 33, and a limiting groove for accommodating the limiting portion is formed on the top surface of the support seat 31, wherein the limiting portion and the limiting groove stop and limit each other in the radial direction. Through the stopping and limiting action between the limiting portion and the limiting groove, it is ensured that the rotating seat 33 will not be radially displaced after being installed on the support seat 31, thereby ensuring that the rotating seat 33 and the energy release buffer layer 2 can rotate normally.

[0025] Furthermore, in order to improve the structural rigidity and stability of the energy release buffer layer 2, a support sleeve 5 is provided on the inner circumference of the energy release buffer layer 2 of the present embodiment, and the energy release buffer layer 2 is coaxially sleeved on the outer circumference of the support sleeve 5, and the rotating seat 33 is fixedly ringed on the inner circumference of the support sleeve 5. Specifically, the rotating seat 33 and the support sleeve 5 can be connected together by welding, bolts, etc., and the energy release buffer layer 2 can be fixed together by gluing, ultrasonic welding, etc. Those skilled in the art can adjust the above-mentioned connection methods according to actual production requirements.

[0026] In this embodiment, the contact surface layer 4 is covered and sleeved on the outer surface of the energy release buffer layer 2. The outer surface of the contact surface layer 4 is a smooth surface with a small friction coefficient. Here, the smooth contact surface layer 4 is used as the contact surface with the external object (such as a ship), thereby effectively reducing the friction with the external object, making the external object slide relative to the contact surface, playing a sliding guide effect, and avoiding the friction between the contact surface layer 4 and the external object, which hinders the movement of the external object and generates a greater impact force. Secondly, the material of the contact surface layer 4 can be selected from polymer or metal materials (such as polymers such as rubber, fluorine materials, silicon materials, or metal materials such as stainless steel). This material not only has excellent corrosion resistance and wear resistance, but also can maintain its smooth surface characteristics during long-term use, ensuring the long-term use effect of the device.

[0027] In addition, the energy release buffer layer 2 is designed to absorb and disperse the impact force when it is impacted externally, protecting the bridge pier from damage. The energy release buffer layer 2 is made of rubber material, which has good elasticity and buffering properties, and can effectively absorb the impact energy and reduce the impact force transmitted to the bridge pier. When an external object such as a ship collides with the device, the impact force is converted into kinetic energy and deformation energy through the sliding energy release of the contact surface layer 4 and the rotational energy release and elastic deformation energy absorption buffering of the energy release buffer layer 2, thereby reducing the impact force on the bridge pier and reducing impact damage.

[0028] In summary, the anti-collision and buffering protection system for bridge piers of this embodiment realizes effective protection of bridge piers through the combined design of the fixed column hoop 1, the energy release buffer layer 2 and the contact surface layer 4. Among them, the rotation design of the energy release buffer layer 2 and the application of the shift bearing group 32 enable the device to respond flexibly when subjected to external forces, and absorb the impact force through the deformation of the energy release buffer layer 2, thereby reducing damage to the bridge piers. At the same time, the smooth surface design of the contact surface layer 4 reduces the friction with external objects, and further plays an energy release effect of transferring the impact force. This type of anti-collision and buffering protection system for bridge piers has the characteristics of simple structure, easy installation, and good buffering effect. It can be widely used in various types of bridge projects to improve the safety and durability of bridges.

[0029] In this embodiment, see the attached Figure 4 and 5As shown, the early warning monitoring device includes a primary detection unit 61 for monitoring state changes of the energy release buffer layer, a secondary monitoring unit 62 for monitoring state changes of the bridge pier, a primary warning unit 71 for issuing warnings based on the state changes monitored by the primary detection unit 61, and a secondary warning unit 72 for issuing safety warnings based on the state changes monitored by the secondary monitoring unit 62, wherein the primary detection unit 61 and the secondary monitoring unit 62 serve as acquisition ends, both of which are connected to the input port of a preset processor, specifically, the primary detection unit 61 is arranged at the energy release buffer layer 2 and is used for real-time monitoring of the state changes of deformation and / or displacement of the energy release buffer layer, that is: when the energy release buffer layer 2 collides with a ship, the energy release buffer layer 2 will be deformed and / or offset to varying degrees due to the different magnitudes of the impact force, and then the primary detection unit 61 detects that a state change has occurred, so that it can be reflected in time through the primary warning unit 71. The secondary monitoring unit 62 is arranged between the bridge pier and the energy release buffer layer 2 and is used to monitor the deformation and / or displacement state changes of the bridge pier in real time, that is: when a ship collides with the energy absorption buffer device to a large extent, the excessive impact force has been transmitted to the bridge pier, thereby causing the bridge pier to deform and / or deflect to varying degrees, which is then detected by the secondary detection unit as a state change, which is a major structural abnormality problem, so that it can be reflected in a timely manner through the secondary warning unit 72.

[0030] In this embodiment, the first-level warning unit 71 and the second-level warning unit 72 serve as functional ends, and both are connected to the output port of the preset processor. Specifically, the first-level warning unit 71 can use warning elements such as warning lights and warning speakers arranged at the bridge piers to issue sound and light warnings to the ship, which is a mild warning level to inform the ship of a collision; the second-level monitoring unit 62 can use stronger warning elements (such as warning lights, warning speakers and other warning elements arranged on the bridge deck) to issue sound and light warnings to ships, passing vehicles on the bridge deck, pedestrians, etc., which is a severe warning level to remind the bridge piers of abnormalities and quickly move away.

[0031] In this embodiment, the primary detection unit 61 and the secondary monitoring unit 62 may use sensors such as radar, infrared sensor, laser, etc.

[0032] In this embodiment, in order to further improve the accuracy and response speed of the early warning monitoring device, a real-time data analysis and processing mechanism is introduced. This mechanism uses a built-in processor to perform real-time analysis on the data collected by the primary detection unit 61 and the secondary monitoring unit 62 to quickly determine the state changes of the energy release buffer layer and the bridge pier. Once an abnormal state is detected, the processor will immediately trigger the corresponding warning unit to ensure that a warning reminder is issued in a timely manner.

[0033] In order to achieve more comprehensive monitoring, multiple sensors are installed at key locations of the piers to form a multi-point monitoring network. These sensors can monitor the deformation and displacement of the piers in different directions in real time, so as to more accurately judge the overall status of the piers.

[0034] At the same time, in order to enhance the warning effect, the first-level warning unit 71 and the second-level warning unit 72 are also optimized. The first-level warning unit 71 uses a high-brightness LED warning light and a loud warning horn to ensure that the ship can clearly receive the warning information even in an environment with insufficient light or high noise. The second-level warning unit 72 uses a more eye-catching warning sign and a stronger sound and light effect to attract the attention of vehicles and pedestrians passing by the bridge deck, reminding them to quickly stay away from possible dangerous areas.

[0035] In addition, a supporting mobile application can be developed, so that users can view the monitoring data and warning information of bridge piers and energy release buffer layers in real time through mobile devices such as mobile phones. In this way, users can understand the operating status of the bridge anytime and anywhere and take corresponding measures in time.

[0036] In summary, this embodiment further improves the accuracy and response speed of the early warning monitoring device by introducing innovative measures such as real-time data analysis and processing mechanism, multi-point monitoring network and optimized warning unit, providing more reliable guarantee for the safe operation of the bridge.

[0037] In summary, the early warning monitoring device and the energy absorption buffer device are two major parts of the bridge pier anti-collision buffer protection system. Among them, the early warning monitoring device serves as a monitoring and alarm reminder after the collision, and the energy absorption buffer device serves as a transfer and energy release function during the collision. The two are used together to effectively reduce the impact force generated by the ship colliding with the bridge pier, and timely and effectively issue a warning of the pier being hit, thereby providing a strong guarantee for the safe operation of the bridge. Once a ship approaches the bridge pier and collides with it, the early warning monitoring device will immediately activate the alarm system and issue a warning to the surrounding area through various means such as sound and light, while the energy absorption buffer device can quickly absorb and transfer the impact energy when a collision occurs, reducing the damage to the bridge pier caused by the impact force.

[0038] In actual application, the early warning monitoring device and the energy absorption and buffer device work closely together. The early warning monitoring device provides timely and accurate monitoring and early warning information; while the energy absorption and buffer device reduces the damage to the bridge piers caused by the collision and protects the safety of the bridge structure through its efficient energy absorption and buffering functions.

[0039] In short, the early warning monitoring device and the energy absorption buffer device of the pier anti-collision buffer protection system work together to form a complete and efficient protection mechanism, providing a solid guarantee for the safe operation of the bridge.
