Description

Technical Field

[0001] The utility model relates to the technical field of pier anti-collision, in particular to a pier anti-collision buffer protection system. Background Technique

[0002] The safety protection of road and bridge piers has always been highly concerned. For the design and construction of pier structures, it is a major topic that engineering and technical designers are committed to researching and is the key guarantee for road and bridge safety. According to research, current pier branches are equipped with anti-collision devices, which have a certain guarantee effect on road and bridge protection, but there are still certain defects and potential hazards, and the comprehensive protection effect of "active prevention and passive anti-collision" has not been achieved. Especially for road and bridge piers that have been constructed, it is often impossible to add relevant anti-collision devices or structures on the existing structure basis. Especially now that the tonnage of ships is getting larger and larger, the existing piers can no longer meet the current anti-collision requirements. In view of this phenomenon, if a pier safety anti-collision system can be designed and applied and installed on existing or newly constructed piers, it can greatly improve the pier safety and reduce the risk of collapse of road and bridges caused by passive collision. Content of the Utility Model

Specific implementation manner

[0021] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the accompanying drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model 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 utility model more thorough and comprehensive.

[0022] Refer to the attached Figures 1-3 As shown, in this embodiment, a bridge pier anti - collision buffer protection system includes an early warning monitoring device and an energy - absorbing buffer device fixedly sleeved outside the bridge pier. Among them, the energy - absorbing buffer device is used to be fixedly sleeved outside the bridge pier to play a buffer protection effect, and specifically includes a fixed column hoop 1 fixedly sleeved outside the bridge pier, an energy - releasing buffer layer 2, and a contact surface layer 4. The fixed column hoop 1 is made of high - strength steel material and is fixedly sleeved on the bridge pier. Here, the fixed column hoop 1 has sufficient rigidity to support the other components and rigidly protect the bridge pier.

[0023] In this embodiment, the energy-releasing buffer layer 2 is coaxially arranged around the fixed column hoop 1 in a ring shape. There is at least one set of rolling components 3 between the energy-releasing buffer layer 2 and the fixed column hoop 1, so that the energy-releasing buffer layer 2 can rotate around the fixed column hoop 1 by means of the rolling components 3. Among them, there are at least two sets of rolling components 3 arranged axially between the energy-releasing buffer layer 2 and the fixed column hoop 1. The specific number of the rolling components 3 is determined by the heights of the fixed column hoop 1 and the energy-releasing buffer layer 2, that is: when the heights of the fixed column hoop 1 and the energy-releasing buffer layer 2 are longer, the number of the rolling components 3 set is correspondingly more. Secondly, each set of the rolling components 3 includes a support seat 31 fixedly arranged in a ring shape on the outer peripheral surface of the fixed column hoop 1, a rotating seat 33 fixedly arranged in a ring shape on the inner peripheral surface of the energy-releasing buffer layer 2, and a number of moving bearing groups 32 clamped and rolled between the support seat 31 and the rotating seat 33. Thus, by the rolling action of the moving bearing groups 32, the rotational connection between the support seat 31 and the rotating seat 33 is realized, so that the energy-releasing buffer layer 2 can perform a rotating action when subjected to an external force.

[0024] In this embodiment, a support ring groove 311 with an annular extension and used for partially supporting and accommodating the moving bearing groups 32 is formed on the top surface of the support seat 31. A rotating ring groove 321 with an annular extension and used for partially pressing and accommodating the moving bearing groups 32 is formed on the bottom surface of the rotating seat 33. The support ring groove 311 and the rotating ring groove 321 are aligned with each other. Here, the support ring groove 311 and the rotating ring groove 321 are used to limit and guide the moving bearing groups 32 at the same time, so as to ensure that the rotational action of the rotating seat 33 and the energy-releasing buffer layer 2 relative to the support seat 31 is more stable and reliable. Especially when the external force received by the energy-releasing buffer layer 2 is transmitted to the rotating seat 33, problems such as the separation of the rotating seat 33 from the support seat 31 and / or the falling off of the moving bearing groups 32 will not occur. In addition, a limiting portion extending downward 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. Among them, the limiting portion and the limiting groove are axially stopped and limited. Through the stopping and limiting action between the limiting portion and the limiting groove, it is ensured that the rotating seat 33 will not have a radial displacement after being installed on the support seat 31, and it is ensured that the rotating seat 33 and the energy-releasing buffer layer 2 can perform a normal rotating action.

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

[0026] In this embodiment, the contact surface layer 4 is wrapped around the outer surface of the energy-releasing buffer layer 2. The outer surface of the contact surface layer 4 is a smooth surface with a small coefficient of friction. Here, the smooth contact surface layer 4 is used as the contact surface with external objects (such as ships), so as to effectively reduce the frictional force with external objects, make the external objects show a sliding effect relative to the contact surface, play a role of sliding guidance, and avoid the contact surface layer 4 and external objects from hindering the movement of external objects due to friction and generating greater impact force. Secondly, the material of the contact surface layer 4 can be selected from polymer or metal materials (such as polymers like rubber, fluorine materials, silicon materials, or metal materials like stainless steel). This kind of material not only has excellent corrosion resistance and wear resistance, but also can maintain the characteristics of its smooth surface during long-term use, ensuring the long-term use effect of the device.

[0027] In addition, the design of the energy-releasing buffer layer 2 is to absorb and disperse the impact force when being externally impacted, and protect the bridge pier from damage. The energy-releasing buffer layer 2 is made of rubber material, and this kind of material has good elasticity and buffering performance, 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, through the sliding energy-releasing effect of the contact surface layer 4 and the rotational energy-releasing and elastic deformation energy-absorbing buffering of the energy-releasing buffer layer 2, the impact force is converted into kinetic energy and deformation energy, thereby reducing the impact force on the bridge pier and reducing the impact damage.

[0028] To sum up, the bridge pier anti-collision buffer protection system of this embodiment realizes the effective protection of the bridge pier through the combined design of the fixed column hoop 1, the energy-releasing buffer layer 2 and the contact surface layer 4. Among them, the rotational design of the energy-releasing buffer layer 2 and the application of the moving bearing group 32 enable the device to respond flexibly when being acted by external forces, and absorb the impact force through the deformation of the energy-releasing buffer layer 2, thereby reducing the damage to the bridge pier. At the same time, the smooth surface design of the contact surface layer 4 reduces the frictional force with external objects, and further plays an energy-releasing effect of transferring the impact force. This kind of bridge pier anti-collision buffer protection system has the characteristics of simple structure, convenient installation and good buffering effect, and can be widely applied to various bridge projects to improve the safety and durability of bridges.

[0029] In this embodiment, see Appendix Figure 4 and 5As shown in the figure, the early warning monitoring device includes a primary detection unit 61 for monitoring the state change of the energy release buffer layer, a secondary monitoring unit 62 for monitoring the state change of the bridge pier, a primary warning unit 71 for issuing a warning reminder based on the state change monitored by the primary detection unit 61, and a secondary warning unit 72 for issuing a safety reminder based on the state change monitored by the secondary monitoring unit 62. Among them, the primary detection unit 61 and the secondary monitoring unit 62 serve as the acquisition ends, and both 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 to monitor the state change of the deformation and / or offset of the energy release buffer layer in real time, that is: when the energy release buffer layer 2 collides with a ship, different degrees of deformation / or offset of the energy release buffer layer 2 will be caused due to different magnitudes of the impact force, and then the state change is detected by the primary detection unit 61, so as to 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 state change of the deformation and / or offset of the bridge pier in real time, that is: when a ship collides with the energy absorption buffer device with a large impact, the excessive impact force has been transmitted to act on the bridge pier, and then different degrees of deformation / or offset of the bridge pier are caused, and then the state change is detected by the secondary detection unit, which belongs to a relatively large structural abnormality problem, so as to be reflected in time through the secondary warning unit 72.

[0030] In this embodiment, the primary warning unit 71 and the secondary warning unit 72 serve as the functional ends, and both are connected to the output port of a preset processor. Specifically, the primary warning unit 71 can adopt warning elements such as warning lights and warning horns arranged at the bridge pier to issue acoustic and optical warning reminders to the ship, which belongs to a mild warning level to inform the ship of a collision; the secondary monitoring unit 62 can adopt relatively strong warning elements (such as warning lights and warning horns arranged on the bridge deck) to issue acoustic and optical warning reminders to ships, passing vehicles and pedestrians on the bridge deck, etc., which belongs to a severe warning level to remind of the abnormality of the bridge pier and stay away quickly.

[0031] In this embodiment, the primary detection unit 61 and the secondary monitoring unit 62 can adopt sensors such as radar, infrared sensors, and lasers.

[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 performs real-time analysis on the data collected by the primary detection unit 61 and the secondary monitoring unit 62 through a built-in processor to quickly judge 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 time.

[0033] To achieve more comprehensive monitoring, multiple sensors are also installed at key positions of the bridge pier to form a multi-point monitoring network. These sensors can monitor the deformation and offset of the bridge pier in different directions in real time, so as to more accurately judge the overall state of the bridge pier.

[0034] At the same time, to enhance the warning effect, the primary warning unit 71 and the secondary warning unit 72 are also optimized. The primary warning unit 71 uses high-brightness LED warning lights and warning horns with loud sounds to ensure that ships can clearly receive warning information even in environments with insufficient light or high noise. The secondary warning unit 72, on the other hand, uses more eye-catching warning signs and stronger sound and light effects to attract the attention of passing vehicles and pedestrians on the bridge deck and remind them to quickly stay away from the potentially dangerous area.

[0035] In addition, a supporting mobile application is also developed, enabling users to view the monitoring data and warning information of the bridge pier and the energy release buffer layer in real time through mobile devices such as mobile phones. In this way, users can understand the operating status of the bridge at any time and take corresponding measures in a timely manner.

[0036] In summary, through innovative measures such as introducing real-time data analysis and processing mechanisms, multi-point monitoring networks, and optimized warning units, this embodiment further improves the accuracy and response speed of the early warning monitoring device, providing a 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 functions as monitoring and alarm reminder after a collision, and the energy absorption buffer device functions as transferring and releasing energy during a collision. When used in combination, they can effectively reduce the impact force generated by a ship colliding with the bridge pier and promptly and effectively issue a warning of the bridge pier being hit, thus providing a strong guarantee for the safe operation of the bridge. Once a ship approaches the bridge pier and a collision occurs, 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 during the collision, reducing the damage to the bridge pier caused by the impact force.

[0038] In practical applications, the early warning monitoring device and the energy absorption buffer device cooperate closely and jointly play their roles. The early warning monitoring device provides timely and accurate monitoring and warning information; while the energy absorption buffer device reduces the damage to the bridge pier caused by the collision through its efficient energy absorption and buffering functions, protecting the safety of the bridge structure.

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