Description

Technical Field

[0001] The invention belongs to the technical field of bridge protection equipment, and in particular relates to a floating bridge anti-collision floating aluminum fender. Background Art

[0002] Bridge anti-collision fenders are protective devices installed on bridge piers, bridge towers and other parts that are vulnerable to ship collisions. They mainly play a key role in buffering and absorbing the impact energy of ships, just like putting on "protective clothing" for the bridge. When a ship accidentally collides, the anti-collision fender disperses and consumes the impact energy through its own characteristics, such as rubber fenders relying on elastic deformation, floating fenders using floating buffers, etc., to avoid or reduce damage to the bridge structure. In actual applications, it can be found in inland waterways, coastal bridges and other places where there is a risk of ship collision. It has various installation forms, which can meet the environment and needs of different bridges and effectively ensure the safety of bridges. For example, the authorization announcement number CN218933021U discloses a bridge pile foundation anti-collision fender.

[0003] At present, the following problems exist in the use of bridge pile foundation anti-collision fenders:

[0004] First, the anti-collision fender lacks an effective pre-collision warning mechanism. When a ship approaches a bridge pier and is about to collide, it cannot issue an alarm to the ship driver in time, causing the ship to directly hit the bridge pier. This collision often causes multiple damages to the bridge structure, such as concrete peeling off the pier, exposed steel bars or even broken steel bars, which may further cause displacement and tilt of the pile foundation, cracking and deformation of the superstructure and other serious problems, greatly threatening the safety and reliability of the bridge and shortening the service life of the bridge. In serious cases, the bridge may even collapse.

[0005] Second, the current bridge pile foundation anti-collision fenders have relatively single functions when dealing with collisions. Most of them can only buffer part of the impact force, but cannot change the collision direction of the ship in time at the critical moment. This causes the bridge to still bear a large residual impact force and cannot effectively reduce the degree of damage to the bridge caused by the collision. The anti-collision effect is greatly reduced, and the bridge is frequently subjected to serious impact damage.

[0006] Therefore, we propose a floating bridge anti-collision floating aluminum fender to solve the above problems. Summary of the invention

[0019] Compared with the existing technology, the advantages of a floating bridge anti-collision floating aluminum fender are:

[0020] 1. Through the U-shaped guide frame, mobile rod, retaining ring and L-shaped connecting aluminum strip, when the anti-collision equipment needs to be installed at the bridge pier during the use of the bridge, the bridge anti-collision floating aluminum fender is first installed on the bridge pier, and the mobile rod is inserted into the rectangular through hole of the U-shaped guide frame, and two retaining rings are welded on the mobile rod for limiting, so that the mobile rod can reliably move up and down in the U-shaped guide frame, and then the first anti-collision mechanism and the second anti-collision mechanism are distributed on the left and right sides of the bridge pier, and after the first anti-collision mechanism and the second anti-collision mechanism are in contact with the water surface, the first anti-collision mechanism and the second anti-collision mechanism are connected to the bridge pier. The first anti-collision mechanism and the second anti-collision mechanism can be adjusted in a self-floating manner according to the water surface position, and then the first anti-collision mechanism and the second anti-collision mechanism will sink one-third of the water surface under the influence of their own gravity and buoyancy, ensuring that the bridge anti-collision floating aluminum fender also has a certain anti-collision effect under the water surface, thereby ensuring the anti-collision reliability of the first anti-collision mechanism and the second anti-collision mechanism. This mechanism enables the bridge anti-collision floating aluminum fender to have a self-floating function, and the anti-collision position of the bridge anti-collision floating aluminum fender can be adjusted according to the water surface position, thereby improving the anti-collision effect and reliability of the bridge anti-collision floating aluminum fender.

[0021] 2. Through the anti-collision warning mechanism, when the ship waves generated when the ship passes too close to the bridge and the water surface at the bridge is affected by the wind and generates large waves, these ship waves and large waves will cause the bridge anti-collision floating aluminum fender to fluctuate, and during the fluctuation process, the laser ranging sensor will measure the length value between the connecting plate. If the absolute value of the difference between the length values ​​measured on both sides exceeds the length change threshold F1 after the difference calculation in the PLC controller, the PLC controller controls the loudspeaker to generate an alarm message. The ship driver receives the warning message from the loudspeaker and drives the ship carefully to avoid the ship colliding with the bridge piers. This mechanism enables the bridge anti-collision floating aluminum fender to not only have the function of warning before the ship collides with the bridge, but also has the function of warning when the wind and waves on the water are too large, reminding the ship driver to drive carefully when crossing the bridge to avoid accidents of colliding with the bridge. This can not only ensure the safety, reliability and life of the bridge, but also improve the effect of the use of the bridge anti-collision floating aluminum fender.

[0022] 3. Through the first anti-collision mechanism, the second anti-collision mechanism, the floating aluminum casing assembly and the auxiliary mechanism, when a ship or a large floating object on the water surface hits a bridge pier, these impact objects will contact the surface of the rubber protective tube in the floating aluminum casing assembly of the first anti-collision mechanism or the second anti-collision mechanism at the beginning of the collision, and at the first time of contact, the rubber protective tube drives the rotating rod to rotate on the arc-shaped aluminum frame through the protective aluminum tube, and the rotating rubber protective tube can change the direction of the impact of the ship or the large floating object on the water surface at the first time, and multiple floating aluminum casing assemblies and auxiliary mechanisms change the impact direction of the ship or the large floating object on the water surface in turn, so as to avoid When a ship or a large floating object on the water hits the bridge pier with all its strength, the safety of the bridge can be ensured. If the impact force of the collision is too great and the rubber protective tube cannot reliably buffer it, the protective aluminum tube and the foam aluminum tube will also deform and absorb energy after being hit by the impact force, further consuming the impact force and avoiding the bridge piers from being damaged by the ship or large floating objects on the water as much as possible. This mechanism enables the bridge's anti-collision floating aluminum fender to change the impact direction in time. After the impact direction is changed in time, the remaining impact force can be prevented from continuing to hit the bridge piers, effectively improving the anti-collision effect and reliability of the bridge's anti-collision floating aluminum fender, while ensuring the safety and reliability of the bridge in continuous use.

[0034] The outer walls of two L-shaped connecting aluminum bars 11 are commonly fixedly connected with a first anti-collision mechanism 4, and the outer walls of the other two L-shaped connecting aluminum bars 11 are commonly fixedly connected with a second anti-collision mechanism 7. The first anti-collision mechanism 4 and the second anti-collision mechanism 7 are symmetrically distributed on the left and right. The structure of the second anti-collision mechanism 7 is consistent with the structure of the first anti-collision mechanism 4. The first anti-collision mechanism 4 includes two arc-shaped aluminum frames 43. A plurality of rotating rods 41 are provided on the opposite sides of the two arc-shaped aluminum frames 43. Both ends of the rotating rods 41 are fixedly sleeved with connecting bearings 42. The outer walls of the two arc-shaped aluminum frames 43 are provided with a plurality of connecting through holes for fixing the connecting bearings 42. The rod wall of the rotating rod 41 is fixedly connected with a floating aluminum casing assembly 5, and an auxiliary mechanism 6 is provided in the gap between the two floating aluminum casing assemblies 5.

[0035] The floating aluminum casing assembly 5 includes a foam aluminum casing 51, a protective aluminum casing 52 and a rubber protective casing 53 fixedly sleeved with the outer wall of the rotating rod 41. The outer wall of the rubber protective casing 53 is fixedly connected with a plurality of rubber anti-skid protrusions 12. The rubber anti-skid protrusions 12 and the rubber protective casing 53 are an integrally formed structure. The rubber anti-skid protrusions 12 can increase the contact area between the rubber protective casing 53 and the ship or large floating objects on the water surface, and ensure that the rotating rubber protective casing 53 can timely and effectively change the collision direction of the ship or large floating objects on the water surface during the rotation process, so as to avoid the ship or large floating objects on the water surface from being hit. The subsequent impact force of the collision with large floating objects on the water surface is all transmitted to the bridge piers. The foam aluminum tube 51 is located on the inner side of the protective aluminum tube 52, and the protective aluminum tube 52 is located on the inner side of the rubber protective tube 53. A plurality of floating buffer cavities 54 are opened inside the rubber protective tube 53. This mechanism enables the bridge's anti-collision floating aluminum fender to have the function of timely changing the impact direction. After the impact direction is changed in time, the remaining impact force can be prevented from continuing to hit the bridge piers, effectively improving the anti-collision effect and reliability of the bridge's anti-collision floating aluminum fender, while ensuring the safety and reliability of the bridge in continuous use.

[0036] The auxiliary mechanism 6 includes a rotating aluminum cylinder 61, the inner wall of the rotating aluminum cylinder 61 is rotatably sleeved with a U-shaped connecting rod 62 through a connecting bearing 42, and the rod walls at both ends of the U-shaped connecting rod 62 are respectively fixedly connected to the outer walls of the two arc-shaped aluminum frames 43. The auxiliary mechanism 6 can prevent ships or large floating objects on the water from being stuck between the two floating aluminum casing assemblies 5 and affecting the anti-collision effect.

[0037] The top of one of the U-shaped guide frames 1 is fixedly connected with an anti-collision warning mechanism 8, and the anti-collision warning mechanism 8 includes a connecting plate 81 and a moving plate 82. The bottom end of the connecting plate 81 is fixedly connected to the upper surface of one of the U-shaped guide frames 1, and the bottom end of the moving plate 82 is fixedly connected to the upper surfaces of two of the L-shaped connecting aluminum bars 11. The side wall of the moving plate 82 is provided with two moving grooves 83 that match the extension of the U-shaped guide frame 1. A laser ranging sensor 84 is fixedly embedded in the top of the moving plate 82. The connecting plate 81 is located directly above the laser ranging sensor 84. A navigation mark warning light 85 and a loudspeaker 86 are fixedly connected to the upper surface of the connecting plate 81. The input ends of the navigation mark warning light 85 and the loudspeaker 86 are electrically connected to a PLC controller 87 through wires. The laser ranging sensor 84 is electrically connected to the input end of the PLC controller 87 through wires. A protective box 88 is fixedly connected to the outer wall of the PLC controller 87. A mounting plate 89 for being fixedly connected to the outer wall of the pier is fixedly connected to the outer wall of the protective box 88. There is a power replenishment mechanism 9, which includes an adjustment bracket 91 fixedly connected to the outer wall of the top end of the protection box 88, a solar panel 92 fixedly connected to the top end of the adjustment bracket 91, an L-shaped frame 93 and a battery 94 fixedly connected to the inner wall of the protection box 88, and a charge and discharge controller 95 fixedly connected to the upper surface of the L-shaped frame 93 for charging and discharging the battery 94. The solar panel 92 is electrically connected to the connection end of the battery 94 through the charge and discharge controller 95, and the battery 94 can also supply power to the powered equipment at the PLC controller 87 through the charge and discharge controller 95. The solar panel 92 can convert solar energy into electrical energy and store it in the battery 94 for use by the bridge anti-collision floating aluminum fender at night, so that the anti-collision warning mechanism 8 in the bridge anti-collision floating aluminum fender has sufficient power supply for working at night. This mechanism enables the bridge anti-collision floating aluminum fender to not only have the function of warning before a ship hits a bridge, but also has the function of warning of excessive wind and waves on the water surface, reminding the ship driver to drive carefully when crossing the bridge to avoid accidents of hitting the bridge.

[0038] The above-mentioned electrical connection and power supply equipment are prior art and are well known to those skilled in the art, and will not be described in detail here.

[0039] The operating principle of the present invention is now described as follows: when it is necessary to install anti-collision equipment at the pier during the use of the bridge, firstly, two U-shaped guide frames 1 are fixed on the bridge pier by installing bolts 14, and the moving rod 2 is inserted into the rectangular through hole of the U-shaped guide frame 1, and two retaining rings 3 are welded on the moving rod 2 for limiting, so that the moving rod 2 can reliably move up and down in the U-shaped guide frame 1, then the first anti-collision mechanism 4 and the second anti-collision mechanism 7 are distributed on the left and right sides of the bridge pier, and after the first anti-collision mechanism 4 and the second anti-collision mechanism 7 contact with the water surface, the first anti-collision mechanism 4 and the second anti-collision mechanism 7 can be self-floatingly adjusted according to the water surface position, then the first anti-collision mechanism 4 and the second anti-collision mechanism 7 will sink one-third of the water surface under the influence of their own gravity and buoyancy, and the floating buffer cavity 54, the protective aluminum tube 52 and the floating aluminum casing assembly 5 The sealing structure of the foam aluminum cylinder 51 enables the first anti-collision mechanism 4 and the second anti-collision mechanism 7 to have a floating effect, ensuring that the bridge anti-collision floating aluminum fender also has a certain anti-collision effect under the water surface, thereby ensuring the anti-collision reliability of the first anti-collision mechanism 4 and the second anti-collision mechanism 7. At the same time, the mounting plate 89 is fixed to the surface of the bridge pier through the connecting piece, and the solar panel 92 can receive sunlight to the maximum extent by adjusting the bracket 91, and convert the solar energy into electrical energy and store it in the battery 94 for the bridge anti-collision floating aluminum fender to use at night, so that the anti-collision warning mechanism 8 in the bridge anti-collision floating aluminum fender has sufficient power supply for night operation. This mechanism enables the bridge anti-collision floating aluminum fender to have a self-floating function, and the anti-collision position of the bridge anti-collision floating aluminum fender can be adjusted according to the water surface position, thereby improving the anti-collision effect and reliability of the bridge anti-collision floating aluminum fender;

[0040] When the bridge anti-collision floating aluminum fender is in use, the laser distance sensor 84 will emit a laser every 2 seconds to measure the length between the connecting plate 81, and the laser distance sensor 84 transmits the measured length value to the PLC controller 87 in the form of an electrical signal. The PLC controller 87 also presets a length change threshold F1 (when the absolute value of the length value change of F1 is 5 cm, that is, the absolute value of the difference between the length values ​​measured twice by the laser distance sensor 84 is 5 cm). Each time the PLC controller 87 receives the length value of the laser distance sensor 84, it will calculate the length value measured last time. If the absolute value of the difference between the two length values ​​measured by the laser distance sensor 84 exceeds the length change threshold F1, the PLC controller 87 promptly controls the speaker 86 to start playing the warning sound, and the navigation mark warning light 85 is controlled by the PLC controller 87 to light up at night. The automatic lighting of the navigation mark warning light 85 is automatically controlled according to the preset night lighting time of the PLC controller 87. After the navigation mark warning light 85 is lit, it can provide a warning to the ship driver at night to avoid the collision of the ship approaching the bridge pier.

[0041] When a ship passes through a bridge, the movement of the ship will generate ship waves in the water around the ship. Such ship waves spread outward, and when they propagate to the bridge's anti-collision floating aluminum fender, the bridge's anti-collision floating aluminum fender will be affected by the ship waves and cause fluctuations. The closer the ship is to the bridge's anti-collision floating aluminum fender, the greater the ship waves the bridge's anti-collision floating aluminum fender will be affected by, and the greater the amplitude of the fluctuation of the bridge's anti-collision floating aluminum fender will be. In this process, the length measured by the laser ranging sensor 84 between itself and the connecting plate 81 will also become smaller and larger, and the bridge's anti-collision floating aluminum fender will float up due to the crest of the ship waves. At this time, the length between the laser ranging sensor 84 and the connecting plate 81 will become smaller, and the bridge's anti-collision floating aluminum fender will fall due to the trough of the ship waves. When the laser distance sensor 84 and the connecting plate 81 are connected, the length between them will increase. During this process, the laser distance sensor 84 will also send an electrical signal of the measured length value to the PLC controller 87, and the PLC controller 87 will calculate the absolute value of the difference between two adjacent measured length values. If the absolute value exceeds the length change threshold F1 preset by the PLC controller 87, it means that the ship crossing the bridge is too close to the pier, causing the bridge anti-collision floating aluminum fender on the pier to fluctuate greatly due to the influence of the ship's traveling waves. At this time, the PLC controller 87 promptly controls the loudspeaker 86 to start issuing an alarm message. After receiving the sound warning played by the loudspeaker 86, the driver on the ship promptly controls the ship to stay away from the bridge pier to avoid the situation where the ship hits the bridge pier.

[0042] In addition, if the water surface at the bridge pier is affected by wind and produces large waves, the large waves will also cause the bridge anti-collision floating aluminum fender of the bridge pier to fluctuate with the water surface waves, and the greater the wind and waves, the greater the amplitude of the fluctuation of the bridge anti-collision floating aluminum fender. Similarly, after the PLC controller 87 calculates that the absolute value of the length difference between the laser ranging sensor 84 and the connecting plate 81 measured twice by the anti-collision warning mechanism 8 exceeds the length change threshold F1, the PLC controller 87 will also control the loudspeaker 86 to sound an alarm to remind the driver of the ship crossing the bridge at this time that the wind and waves on the water surface are large at this time, and then remind the driver to drive the ship carefully to avoid the ship being affected. In addition, when the PLC controller 87 does not control the loudspeaker 86 to alarm, it means that the ship is far away from the bridge pier and no collision accident will occur, or the wind and waves on the water surface at the bridge are small, and the possibility of the ship hitting the bridge during normal driving is small. This mechanism enables the bridge anti-collision floating aluminum fender to not only have the function of warning before the ship hits the bridge, but also has the function of warning when the wind and waves on the water surface are too large, reminding the ship driver to drive carefully when crossing the bridge to avoid accidents of hitting the bridge. This can not only ensure the safety, reliability and life of the bridge, but also improve the effect of the bridge anti-collision floating aluminum fender;

[0043] When a ship or a large floating object on the water surface hits a bridge pier, these impacting objects will contact the surface of the rubber protective tube 53 in the floating aluminum casing assembly 5 of the first anti-collision mechanism 4 or the second anti-collision mechanism 7 at the initial stage of the impact, and at the first moment of contact, the rubber protective tube 53 drives the rotating rod 41 to rotate on the arc-shaped aluminum frame 43 through the protective aluminum tube 52, and the rotating rubber protective tube 53 can change the direction of the impact of the ship or the large floating object on the water surface at the first moment, and multiple floating aluminum casing assemblies 5 and auxiliary mechanisms 6 change the impact direction of the ship or the large floating object on the water surface in turn, and try to avoid the ship or the large floating object on the water surface from hitting the bridge pier with all its strength, thereby ensuring the safety of the bridge. In this process, the rubber anti-slip protrusions 12 can increase the contact area between the rubber protective tube 53 and the ship or the large floating object on the water surface. The rubber anti-slip protrusions 12 and the rubber protective tube 53 are both made of fluororubber, which is resistant to chemical corrosion and can be used reliably for a long time. , and ensure that during the rotation of the rotating rubber protective tube 53, the impact direction of the ship or large floating objects on the water surface can be changed effectively and timely, so as to prevent the subsequent impact force of the ship or large floating objects on the water surface from being transmitted to the bridge piers. In addition, the rubber protective tube 53 will also be deformed in the early stage of the impact, and assisted by the floating buffer cavity 54 during the deformation process, it has a high efficiency impact buffering effect. If the impact force of the impact is too large and the rubber protective tube 53 cannot reliably buffer, the protective aluminum tube 52 and the foam aluminum tube 51 will also be deformed and absorb energy after receiving the impact force, further consuming the impact force of the impact, and avoiding the bridge piers from being damaged by the ship or large floating objects on the water surface as much as possible. This mechanism enables the bridge anti-collision floating aluminum fender to have the function of changing the impact direction in time. After the impact direction is changed in time, the remaining impact force can be prevented from continuing to hit the bridge piers, effectively improving the anti-collision effect and reliability of the bridge anti-collision floating aluminum fender, while ensuring the safety and reliability of the continuous use of the bridge.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
