Description

Technical Field

[0001] The utility model relates to the technical field of bridge protection, in particular to a hidden bridge pier anti-collision warning structure. Background Art

[0002] The pier anti-collision warning structure is an important part of bridge safety. It is used to monitor and warn of possible ship collisions. In recent years, a new type of hidden pier anti-collision warning structure has gradually attracted attention. This structure is set on the surface of the pier, which does not affect the appearance of the bridge and can effectively monitor the surrounding environment. When a ship approaches the pier, the structure can quickly sense and send out a warning signal to remind the ship driver to adjust the route to avoid collision. This hidden pier anti-collision warning structure not only improves the safety of the bridge, but also reduces maintenance costs, providing a strong guarantee for the long-term stable operation of the bridge.

[0003] In the prior art, a Chinese patent document with publication number CN210827343U proposes a bridge pier anti-collision warning device, including a fixed frame, two fixed frames in a "U"-shaped structure, ear plates are installed on both sides of the fixed frame close to the opening, a through hole is provided inside the ear plate, and a connecting piece is provided inside the through hole for realizing the connection of the two fixed frames. Although the elastic buffer rod and the anti-collision plate can provide buffering and anti-collision protection for the pier, the use effect is good, and the overall disassembly and assembly are convenient, which is convenient for maintenance and replacement, but the technology is consistent with the traditional method in that the height of the horizontal plane on the river or sea surface is different in different environments and seasons. In different environments and seasons, the rise and fall of the horizontal plane will cause the change of the navigation height of the ship, thereby changing the position where the collision with the pier may occur. If the entire outer surface of the pier is covered with an anti-collision warning structure, it is not only costly, but also impractical. The anti-collision warning structure in the prior art cannot be flexibly adjusted with the movement of the horizontal plane, which makes it possible for the anti-collision warning structure to fail to achieve the expected anti-collision and warning effects when the horizontal plane changes. In addition, when the existing technology is used for early warning, the warning distance between the ship and the bridge pier is difficult to adjust, resulting in the early warning structure being difficult to adapt to the different specifications and sailing speeds of ships in the area during use, which to a certain extent reduces the convenience and effectiveness of use.

[0004] Furthermore, we disclose a hidden bridge pier anti-collision warning structure to meet the needs that the anti-collision warning structure in the prior art cannot be flexibly adjusted with the movement of the horizontal plane and the warning distance between the ship and the bridge pier is difficult to adjust.

Because the piston is tightly fitted with the inner wall of the bent pipe, the piston drives the gas to blow into the warning whistle when moving upward, so that the warning whistle makes a sound to warn the ship driver. The rotatable roller on the bent pipe makes the pull rope move more conveniently. The elastic force of the second buffer spring seat is greater than the reset spring, so that the piston can move downward when the second buffer spring seat is reset.
