Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier anti-collision devices, in particular to a bridge pier anti-collision device for water transport channels. Background Art

[0002] With the rapid development of the world economy, shipping is developing rapidly, and the volume of river and sea shipping is increasing. The maintenance of shipping and water buildings is particularly important. The pier anti-collision device is used in many scenarios, such as estuary bridges, island buildings, port terminals, underwater tunnels, etc., to protect these buildings and bridges from damage caused by ship collisions.

[0003] Existing anti-collision devices for waterway piers are usually equipped with warning devices during use to alert passing ships and prevent ships from colliding with the piers. However, the use of the warning devices in various harsh environments such as seawater corrosion and mud impact will cause damage to the electronic components in the warning devices, and they need to be replaced regularly to ensure the stability of the operation of the warning devices. Usually, the warning devices need to be fixed into the pier using multiple sets of bolts. When replacing, the operator needs to use tools to remove the bolts one by one. The operation steps are complicated, which prolongs the time for device replacement and maintenance and reduces the continuity of device operation. In addition, when a ship loses control and collides with a pier, since the anti-collision devices usually do not have a mechanism to protect the piers, the impact force caused by the collision cannot be reduced, resulting in damage to the piers, causing serious traffic interruptions and safety accidents, affecting the public's travel safety.

[0004] Therefore, it is necessary to provide a new device for preventing collision of waterway piers to solve the above technical problems. Utility Model Content

A device for preventing collision of waterway piers includes a pier body 1, a fixed plate 2 is arranged on the outside of the pier body 1, and also includes: a protective plate 3 arranged on one side of the fixed plate 2 to protect the pier, an energy absorbing block 4 for reducing the impact of collision is arranged on the outside of the protective plate 3, a first buffer assembly 5 and a second buffer assembly 7 are fixedly connected to one side of the fixed plate 2, a rotating assembly 6 is arranged on one side of the second buffer assembly 7, and a guide assembly 8 is arranged on the inner side of the protective plate 3; a connection assembly 9 is arranged on one side of the fixed plate 2, a limiting hole 10 and a limiting block 11 are arranged on the top of the connection assembly 9, and a warning assembly 12 for preventing ship collision is arranged on one side of the connection assembly 9.

[0024] It should be noted that: by setting the protection plate 3, the bridge pier is protected to prevent the possible collision caused by the loss of control of the ship; by setting the energy absorbing block 4, the material of the energy absorbing block 4 is the foam material EPP, which is a highly crystalline polymer with the characteristics of light weight, good cushioning performance, good plasticity and recyclability. This material can effectively absorb and disperse the impact energy and reduce the damage of the impact force to the bridge pier; by setting the limiting hole 10, it is convenient to limit the limiting block 11 after the limiting block 11 enters the inside; by setting the limiting block 11, the limiting block 11 can be tightly inserted into the limiting hole 10 to achieve the fixed connection between the card slot 92 and the card block 91;

[0025] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, the first buffer assembly 5 includes a damping rod 51 fixed to one side of the fixing plate 2 , and a first spring 52 is sleeved on the outer side of the damping rod 51 .

[0026] The rotating assembly 6 includes a connecting seat 61 fixed to one side of the protective plate 3 , and a rotating rod 62 is rotatably connected to the inner side of the connecting seat 61 .

[0027] The second buffer assembly 7 includes a slide seat 71 disposed at one end of the rotating rod 62 . A slide rod 72 is slidably connected to the inner side of the slide seat 71 . A second spring 73 is sleeved on the outer side of the slide rod 72 .

[0028] The guide assembly 8 includes a guide rod 81 fixed to one side of the fixing plate 2 , and a guide groove 82 is formed on the inner side of the protection plate 3 .

[0029] It should be noted that: by setting the first buffer component 5, the impact generated when a collision occurs is reduced and the protection capability of the bridge pier is improved; by setting the connecting seat 61, one end of the rotating rod 62 is convenient to rotate inside the connecting seat 61; by setting the rotating rod 62, when a collision occurs, the protective plate 3 is moved toward the pier body 1 by the impact force, and at the same time, one end of the rotating rod 62 is squeezed to drive the sliding seat 71 to move; by setting the sliding seat 71, the second spring 73 is squeezed when an impact occurs, and the elastic force of the second spring 73 reduces the impact of the collision impact on the bridge pier; by setting the sliding rod 72, a guide is provided for the movement of the sliding seat 71, and the stability of the movement of the sliding seat 71 is improved; by setting the second spring 73, the impact force generated by the collision is reduced by its own resilience, and by setting the guide component 8, a guide is provided for the protective plate 3 when it moves under the impact force.

[0030] refer to Figure 1 , Figure 2 and Figure 4 As shown, the connecting assembly 9 includes a clamping block 91 fixed to one side of the fixing plate 2 , and a clamping groove 92 is clamped on the outer side of the clamping block 91 .

[0031] The warning component 12 includes a distance meter 121 disposed on one side of the card slot 92 , and a warning light 122 and a speaker 123 are disposed on both sides of the distance meter 121 .

[0032] It should be noted that: by setting up the connecting component 9, it is convenient to quickly connect when replacing the warning component 12, thereby improving the efficiency and stability of the connection; by setting up the rangefinder 121, the distance between the nearby ships and the pier body 1 can be measured. When reaching the dangerous range, the alarm command is transmitted to the PLC controller, and then the flashing of the warning light 122 is accelerated, and the speaker 123 is turned on to sound an alarm to remind the ship to avoid; by setting up the warning light 122, the flashing of the light source can be used to warn passing ships; by setting up the speaker 123, an alarm can be sounded to remind when visibility is low or the ship is only in a dangerous area.

[0033] The working principle of the anti-collision device for waterway bridge piers provided by the utility model is as follows:

[0034] During use, when the warning component 12 needs to be replaced, the limit block 11 is pulled upward to be pulled out of the limit hole 10, so that the card block 91 slides inside the card slot 92 to disengage the connection, which facilitates the rapid disassembly of the warning component 12 after it is damaged, thereby improving the efficiency and stability of the connection. When the ship loses control and collides with the pier body 1, the energy-absorbing block 4 first buffers the impact force, and then the protective plate 3 is moved toward the pier body 1 by the impact force, and at the same time, the rotating rod 62 is squeezed to rotate on the inner side of the connecting seat 61, and the other end of the rotating rod 62 drives the sliding seat 71 to move. The sliding seats 71 arranged at both ends of the sliding rod 72 squeeze the second spring 73 on the inner side, and the elastic force of the second spring 73 reduces the impact of the collision on the pier. At the same time, the four first buffer components 5 arranged in a distributed manner further reduce the impact force, thereby reducing the damage to the pier body 1.
