Technical Field
[0001] The utility model relates to the technical field of bridge pier anti-collision, in particular to a rotatable floating device for bridge pier anti-collision. Background Art
[0002] Bridge piers are the intermediate supporting structures of bridges with two or more spans, excluding the abutments at each end that connect to the embankment. Some existing bridges are built over rivers, lakes, and other structures, while others are built on roads. With the rapid advancement of technology and improvements in people's living standards, the number of cars on roads and ships on rivers is increasing. The increasing density of these vehicles is also increasing the probability of collisions between cars or ships and bridge piers. Although bridge collapses caused by ships colliding with piers are relatively rare, such collisions can significantly reduce the service life of the piers and endanger the safety of people on board.
[0003] There are many kinds of existing bridge pier anti-collision devices, most of which are in the form of reinforced guardrails or fences, and blocks are set in the form of reinforced concrete casting. This not only affects the appearance of the bridge and is inconvenient to construct, but also the rigid concrete blocks have no energy absorption function and the anti-collision effect is poor.

[0006] By adopting the above technical solution, the anti-collision and buffering effect on the bridge pier is achieved.
[0007] The width of the protrusion is adapted to the width of the arc-shaped groove.
[0008] By adopting the above technical solution, the protruding portion can stably rotate at the arc groove.

[0010] By adopting the above technical solution, buffering of the anti-collision part is achieved.
[0011] There are eight anti-collision parts, which are distributed at equal angles on the anti-collision layer.
[0012] By adopting the above technical solution, anti-collision and buffering are performed in multiple directions.

[0015] The beneficial effects of the rotatable floating device for preventing collision of bridge piers of the utility model are:
[0016] After the device is hit, it will touch the outer ring plate, and then the outer ring plate will be squeezed to the anti-collision part, and the anti-collision part will move toward the inside of the buffer groove, and then squeeze the second spring and the buffer seat. At this time, the two buffer seats will be subjected to force and extend from the upper and lower ends of the anti-collision layer respectively. The impact force exerted on the anti-collision part is buffered by the second spring and the buffer seat. In addition, because the ship will continue to rub against the movement of the device during the collision, the anti-collision layer will be subjected to force and rotate around the floating body through the protrusion, and release the force again, so as to better protect the bridge pier and play a role in buffering and anti-collision.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0024] Reference Figure 1-5 A rotatable floating device for bridge pier collision prevention includes two floating bodies 1 connected to form a ring by a connecting portion 2. An anti-collision buffer mechanism is provided on the outside of the floating body 1. The anti-collision buffer mechanism includes an anti-collision layer 3, a protrusion 4, an anti-collision portion 6, a spring 7, a buffer seat 8, a spring 9, a clamping portion 10, and an outer ring plate 11. The anti-collision layer 3 is composed of two and is connected by a connecting portion 5 to form a ring structure. The anti-collision layer 3 is embedded in the arc groove 101 of the floating body 1 through the protrusion 4. To allow the anti-collision layer 3 to rotate around the floating body 1, the anti-collision parts 6 are provided in multiple configurations and are installed one-to-one in multiple buffer grooves 301 provided on the outer wall of the anti-collision layer 3. They are elastically connected to the anti-collision layer 3 via spring 2 9. Two buffer seats 8 are provided in each buffer groove 301, one above the other, and are installed in the buffer groove 301 via spring 1 7. The clamping part 10 is installed on the outer wall of the anti-collision part 6. The outer ring plate 11 is arranged in series to connect the clamping parts 10 on the outer walls of all anti-collision parts 6.
[0025] Connection part 1 2 and connection part 2 5 are both composed of connecting plates and bolts. The two floats 1 are detachably connected by the connecting plates and bolts, which is convenient for subsequent maintenance and replacement. Similarly, the two anti-collision layers 3 are detachably connected by the connecting plates and bolts, which is also convenient for subsequent maintenance and replacement, and the device is easy to install.
[0026] The width of the protrusion 4 is adapted to the width of the arc groove 101; the setting of the float 1 enables the device to float on the water surface and has strong adaptability, and the protrusion 4 is embedded in the arc groove 101. After the device is hit, it can further release force by rotating to achieve buffering and collision prevention for the bridge pier.
[0027] The buffer seat 8 is arranged in a right-angled trapezoidal structure, and its inclined surface is arranged toward the anti-collision part 6. Slots are opened above and below the buffer groove 301. The two buffer seats 8 located at the buffer groove 301 can extend out of the outside of the anti-collision layer 3 through a corresponding slot respectively; after the anti-collision part 6 is hit, it will squeeze the spring 2 9 and the buffer seat 8. At this time, the two buffer seats 8 will stretch the spring 1 7 after receiving the extrusion force transmitted by the anti-collision part 6. The upper buffer seat 8 will move upward, and the lower buffer seat 8 will move downward to release the force. After the anti-collision part 6 is no longer hit or squeezed, the anti-collision part 6 will be bounced back to its original position by the spring 2 9 and the buffer seat 8.
[0028] There are eight anti-collision parts 6, which are distributed at equal angles on the anti-collision layer 3; because the collision angle of the ship is not fixed, the anti-collision parts 6 are set in eight directions, which can effectively release the force transmitted from the ship and play an anti-collision role on the bridge pier.
[0029] The outer wall of the anti-collision part 6 is arranged in an arc-shaped structure, and the clamping part 10 is installed in the middle of the outer wall of the anti-collision part 6. After the outer ring plate 11 passes through each clamping part 10, it is arranged in a closed loop; after the ship collides with the outer ring plate 11, the adjacent anti-collision part 6 will be forced to squeeze the spring 2 9 and the buffer seat 8, and then the spring 2 9 and the buffer seat 8 will realize buffering and releasing force on the anti-collision part 6.
[0030] Working Principle: During installation, the two buoys 1 are mounted around the bridge pier and connected via the first connection 2. When installing the anti-collision layer 3, the protrusion 4 is embedded in the outer arc groove 101 of the buoy 1 to complete the splicing of the two anti-collision layers 3. The two anti-collision layers 3 are then fixed via the second connection 5. At this point, the outer ring plate 11 can be inserted through the clamping parts 10 on the outer walls of the multiple anti-collision parts 6 to connect them. Finally, the outer ring plate 11 is connected at both ends to form a closed loop.
[0031] After the device is hit, it will touch the outer ring plate 11, and then the outer ring plate 11 will squeeze the anti-collision part 6, and the anti-collision part 6 will move toward the inside of the buffer groove 301, and then squeeze the spring 2 9 and the buffer seat 8. At this time, the two buffer seats 8 will be subjected to force and extend from the upper and lower ends of the anti-collision layer 3 respectively. The impact force exerted on the anti-collision part 6 is buffered by the spring 2 9 and the buffer seat 8. In addition, because the ship will continue to rub against the movement of the device during the collision, the anti-collision layer 3 will be subjected to force and rotate around the floating body 1 through the protrusion 4, and the force will be released again, so as to better protect the bridge pier and play a role in buffering and anti-collision.
[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
