[0002] A bridge is a building structure used to cross obstacles on the ground, such as rivers, roads, railways, etc., so that vehicles, pedestrians or other means of transportation can pass through. A bridge is usually composed of piers, abutments, bridge decks and bridge bearings.

[0003] In recent years, with the rapid development of waterways, navigable ships have tended to be larger, faster and more dense, and there are more and more bridge structures in navigable waters. Against the background of increasing navigation density, the ship-bridge contradiction will become increasingly prominent, and the possibility of serious ship-bridge collision accidents will become increasingly high. Therefore, bridges with high navigation density and high navigation requirements are usually equipped with protective devices. Common protective devices are divided into self-floating and fixed types.

Although they have a certain buffering effect, they cannot disperse the force and reduce the impact well when the ship collides with the bridge during driving. It may even cause the ship to lose control and break through the protective device, which cannot effectively reduce the damage caused by the collision. Therefore, a self-floating bridge protective device is proposed to address the above problems. Utility Model Content

During work, when the staff is installing the protective facility 2, they can pull up the fixing rod 305, which will drive the square plate 306 to move upward and squeeze the tension spring 307, and then insert the connecting piece 302 into the connecting groove 301, and then release the fixing rod 305, and the square plate 306 and the fixing rod 305 can be pushed downward under the action of the rebound force of the tension spring 307, and the fixing rod 305 can be inserted into the fixing hole 303, so that the protective facility 2 can be quickly installed, and it is convenient for the staff to disassemble the protective facility 2 for maintenance or replacement later.

[0028] Further, such as Figure 1 and Figure 2 As shown, the top of the protective device 2 is fixedly connected to the limit rod 4 and is located on the inner side of the U-shaped member 304, and the square plate 306 is slidably connected to the surface of the limit rod 4. During operation, when the fixed rod 305 drives the square plate 306 to move, the square plate 306 will slide on the surface of the limit rod 4, thereby playing an auxiliary limiting role for the square plate 306 and the fixed rod 305, preventing the square plate 306 and the fixed rod 305 from deviating during movement, so that the fixed rod 305 cannot be accurately matched and connected with the fixing hole 303.

[0033] Working principle: When a ship hits the bridge column 1, it will first hit the rotating barrel 207, causing the rotating barrel 207 to rotate on the inner side of the mounting member 206 along the direction of the ship's impact, converting the huge impact force into rotational kinetic energy. At the same time, the rotating barrel 207 will be squeezed and slide inward inside the mounting member 206, and will squeeze the compression spring 209 and the telescopic rod 210, which can provide a buffer for the rotating barrel 207. When the rotating barrel 207 is subjected to a large impact force, the rotating barrel 207 will squeeze the buffer plate 205 inward. After being squeezed, the buffer plate 205 will push the sliding block 202 to slide outward on the surface of the vertical rod 201 through the connecting rod 204. The sliding block 202 will squeeze the buffer spring 203 while sliding outward, and under the action of the buffer spring 203, the force received by the buffer plate 205 will be buffered for a second time, which can not only well It plays a role in dispersing force to prevent the ship from losing control. At the same time, the impact force on the ship and the bridge column 1 can be reduced under the action of the buffer mechanism, thereby effectively reducing the damage caused by the collision of the ship and the bridge column 1, and playing a good protective role for the bridge column 1. When the staff is installing the protective facility 2, the fixing rod 305 can be pulled up, which will drive the square plate 306 to move upward and squeeze the tension spring 307, and then the connecting piece 302 is inserted into the interior of the connecting groove 301, and then the fixing rod 305 is released by hand, and the square plate 306 and the fixing rod 305 can be pushed downward again under the action of the rebound force of the tension spring 307, and the fixing rod 305 is inserted into the interior of the fixing hole 303, so that the protective facility 2 can be quickly installed, and it is convenient for the staff to disassemble the protective facility 2 for maintenance or replacement at a later time.
