Description

Technical Field

[0001] The utility model belongs to the technical field of bridge protection, and in particular relates to a bridge anti-collision device. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly; a bridge generally includes a span structure, abutments, piers, and foundations; the piers are used to support the span structure and provide stable support for the upper part of the bridge; the piers ensure the stable operation of the bridge by bearing the bridge's own weight and transferring its own weight to the foundation.

[0003] River shipping is one of the important modes of transportation and freight. During the shipping process, ships may collide with bridge piers due to avoidance or improper operation, causing structural damage and deformation of the piers, affecting the stable operation of the bridge. In order to protect the piers, anti-collision devices are usually installed on the piers to buffer the impact force when the ship collides; however, the current anti-collision devices do not cover the entire pier, but are set at a fixed position on the pier. If the water level rises during the rainy season, the anti-collision device is likely to be submerged below the water level; and the position of the ship rises with the water level; at this time, the anti-collision device will not be able to protect the ship from collision.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example 1

[0041] A bridge anti-collision device, comprising: a bridge pier clamp 1, a floating cylinder 3, a buffer component, an anti-collision plate 4, and a floating plate 5;

[0042] The pier clamp 1 is arranged on the pier and covers the outer wall of the pier; the pier clamp 1 can be arranged as two symmetrical semi-cylindrical structures, the two halves of the clamp respectively cover the pier, and can cover the entire pier after closing; each half of the pier clamp 1 is provided with a fixing loop, and a screw hole is opened on the fixing loop; the locking screw is used to lock and fix the semi-cylindrical clamp after the two halves are closed; and the clamp is fixed to the pier at the same time.

[0043] In this embodiment, the pier hoop 1 is cylindrical; however, its specific shape and structure can be determined according to the shape and structure of the pier itself; for example, if the pier is a rectangular columnar structure, the pier hoop 1 is also correspondingly set to a rectangular columnar structure.

[0044] like Figure 1 A floating cylinder 3 is arranged on the outer periphery of the bridge pier clamp 1, and there is no contact between the floating cylinder 3 and the bridge pier clamp 1; the floating cylinder 3 is only sleeved on the outer periphery of the bridge pier clamp 1, and relative to the bridge pier clamp 1, the floating cylinder 3 can be freely raised and lowered;

[0045] A floating plate 5 is disposed on the lower bottom edge of the floating cylinder 3 . In this embodiment, one floating plate 5 is disposed on each of the left and right sides of the floating cylinder 3 , and the two floating plates 5 are completely symmetrical.

[0046] An anti-collision plate 4 is arranged on the periphery of the floating cylinder 3, and the anti-collision plate 4 can completely cover the floating cylinder 3; a fixed distance is maintained between the anti-collision plate 4 and the periphery of the floating cylinder 3; within this distance, a buffer component is arranged, and the anti-collision plate 4 and the floating cylinder 3 are connected by the buffer component; multiple groups of buffer components can be arranged, and the multiple groups of buffer components arranged need to be evenly distributed, so that no matter where the impact point occurs on the anti-collision plate 4, it is ensured that there can be a corresponding buffer component for buffering and absorption; if a collision occurs between ships, it will first act on the anti-collision plate 4, and the impact force generated by the collision will be dispersed under the buffering and absorption action of the buffer component, so as to avoid the strong impact force being transmitted to the pier through the floating cylinder 3 and the pier clamp 1.

[0047] like Figure 2 , the buffer assembly in this embodiment includes: a damping rod 401 and a spring 402;

[0048] The base end of the damping rod 401 is arranged on the outer wall of the floating cylinder 3, and the telescopic piston end is arranged on the inner wall of the anti-collision plate 4; the spring 402 is arranged on the outer periphery of the damping rod 401, and the spring 402 itself has no contact with the damping rod 401; one end of the spring 402 is arranged on the outer wall of the floating cylinder 3, and the other end is arranged on the inner wall of the anti-collision plate 4. The impact force when a collision occurs is absorbed and dispersed under the joint buffering effect of the spring 402 and the damping rod 401; at the same time, the anti-collision plate 4 will move closer to the direction of the floating cylinder 3 under the action of the force; the damping rod 401 is an existing product, and it will be compressed when it is subjected to force. When the force disappears, the telescopic piston section of the damping rod 401 will recover by itself, and the spring 402 will also recover from the elastic deformation. In the process of self-recovery of the telescopic piston section of the damping rod 401 and the spring 402, the anti-collision plate 4 moves away from the floating cylinder 3 and returns to its original position.

[0049] As a preferred embodiment, the base end and the telescopic piston end of the damping rod 401 are connected to the outer wall of the floating cylinder 3 and the inner wall of the anti-collision plate 4 by adopting a disassembly structure; the disassembly structure can be realized in the form of a screw and a nut; a section of screw is arranged on the outer wall of the floating cylinder 3 and the inner wall of the anti-collision plate 4, and a section of screw is also arranged on the base end and the telescopic piston end of the corresponding damping rod 401, and a nut is arranged on the screw; the screw at the base end of the damping rod is aligned with the screw on the outer wall of the floating cylinder 3, and the screw at the telescopic piston end of the damping rod is aligned with the screw on the inner wall of the anti-collision plate, and then the nut is turned to connect and lock the two sections of screw.

[0050] Since the impact may occur from different directions of the bridge pier, if the anti-collision plate 4 is a whole piece, then the impact in any direction will affect the entire anti-collision plate 4; therefore, the anti-collision plate 4 is divided into several independent pieces with the same structural size;

[0051] like Figure 1 or Figure 5 As shown, in this embodiment, four anti-collision plates 4 are arranged at equal intervals around the floating cylinder 3; after the four anti-collision plates 4 are surrounded, the floating cylinder 3 can be covered; after the impact force in one direction acts, it affects the anti-collision plate 4 where the impact force is concentrated, or the adjacent anti-collision plate 4 is affected, but the anti-collision plates 4 on the opposite side or at a farther distance will not be affected.

[0052] The above-mentioned floating cylinder 3 and anti-collision plate 4 are made of light and high-strength materials, such as aluminum alloy, titanium alloy or other composite materials; the floating plate 5 is made of composite plastic or polyurethane material floating plate;

[0053] The area of ​​the floating plate 5 is as large as possible. The floating plate 5 floats on the water surface and uses buoyancy to support the floating cylinder 3 and the buffer assembly and the anti-collision plate 4 connected to the floating cylinder 3. No matter how the water level changes, under the action of the floating plate 5, the floating cylinder 3 and the anti-collision plate 4 are always above the water surface. In this way, when the water level rises during the rainy season, the anti-collision device can be prevented from being submerged under the water surface and unable to protect against collisions with ships on the water surface.

[0054] Example 2

[0055] Based on Example 1, in Example 1, the floating cylinder 3 is directly and movably arranged on the outer periphery of the pier clamp 1, although there is no direct contact connection between the two and there is a gap between the two; however, during the rising and falling process of the floating cylinder 3, the inner wall of the floating cylinder 3 will still touch the outer wall of the pier clamp 1 to generate friction; this friction force will be the direct resistance for the floating plate 5 to drive the floating cylinder 3 and the anti-collision plate 4 to float and rise with the water level line.

[0056] like Figure 3 or Figure 4 As shown, in order to eliminate or reduce the resistance as much as possible, in this embodiment, an inner cylinder 2 is arranged between the outer wall of the bridge pier clamp 1 and the inner wall of the floating cylinder 3, and the inner cylinder 2 is directly connected to the outer wall of the bridge pier clamp 1; a plurality of spherical grooves are provided on the outer wall of the inner cylinder 2; rolling balls 201 are movably arranged in the spherical grooves, and the rolling balls 201 can rotate freely in the spherical grooves, but are stuck in the spherical grooves and will not fall off. The surface of the rolling balls 201 can contact the inner wall of the floating cylinder 3.

[0057] When the floating plate 5 drives the floating cylinder 3 and the anti-collision plate 4 to rise with the water surface, due to the existence of the rolling ball 201, the inner wall of the floating cylinder 3 will contact the surface of the rolling ball 201, and the friction resistance of the rise can be reduced during the rising process.

[0058] Example 3

[0059] Based on the first or second embodiment, the floating board 5 supports the structural components including the floating cylinder 3, the buffer assembly and the anti-collision plate 4; and the above components need to be kept floating on the water surface; and when the water level rises, the floating board 5 needs to rise with the water level and always be above the water surface; this requires that the floating board 5 has sufficient buoyancy on the water surface and is not too damaged; however, the floating board 5 only relies on the buoyancy of natural water to achieve floating support. Once the buoyancy changes, the floating cylinder 3 and the anti-collision plate 4 may fall;

[0060] In this embodiment, in order to ensure that the floating cylinder 3, the buffer assembly and the anti-collision plate 4 can still float smoothly on the water surface and rise with the water level when the buoyancy of the floating plate 5 changes; a backup structure for the floating cylinder 3 to float is provided;

[0061] like Figure 2 As shown, the backup structure includes: an electrically controlled rotor pulley 8 and a pulling rope 701; the electrically controlled rotor pulley 8 is arranged on the upper edge of the inner cylinder 2, and one electrically controlled rotor pulley 8 is arranged on each side; the two electrically controlled rotor pulleys 8 are symmetrically arranged; the electrically controlled rotor pulley 8 is a prior art, and its structural design and working principle are not described in detail here; the pulling rope 701 is coiled on the electrically controlled rotor pulley 8, and the lower end of the pulling rope 701 is a free end, and the lower end of the pulling rope 701 is connected to the upper edge of the floating cylinder 3.

[0062] The electrically controlled rotor pulley 8 rotates forward or backward to retract or release the pulling rope 701, so that the floating cylinder 3 together with the buffer assembly and the anti-collision plate 4 thereon can be lifted or lowered.

[0063] When relying on the natural buoyancy of the water surface, the floating plate 5, the floating cylinder 3 and the anti-collision plate 4 cannot float normally on the water surface or cannot rise with the rise of the water surface; at this time, it is necessary to turn on the electrically-controlled rotor pulley 8 and use the electrically-controlled machinery to lift the floating cylinder 3 and the anti-collision plate 4 to prevent the floating plate 5, the floating cylinder 3 and the anti-collision plate 4 from being submerged when the water level rises.

[0064] Example 4

[0065] Based on Example 1, if the rainy season comes and the water level rises, the distance between the water surface and the bottom of the bridge deck will gradually shorten; at this time, the distance between the highest point of the ship sailing on the water and the bottom of the bridge deck will also gradually shorten; until the water level rises to the point where the ship cannot pass through the bridge deck; in this case, if the ship makes an inaccurate judgment and forces its way through without being intercepted, it will inevitably cause a collision with the bridge deck, which may seriously affect the structure of the bridge deck and destroy the overall balance and stability of the bridge.

[0066] Therefore, in this embodiment, an interception component for ships is provided; the interception component is arranged on two opposite anti-collision plates 4 on two adjacent bridge piers. That is to say, after the interception components on the two opposite anti-collision plates 4 are lowered, the communication channel formed between the two adjacent bridge piers can be blocked to prevent the ship from forcibly passing through.

[0067] like Figure 1 As shown, in this embodiment, the interception assembly includes: an interception rod 7 and an interception rod driving assembly; the interception rod driving assembly is arranged on the outer wall of the anti-collision plate 4, and the interception rod 7 is arranged on the interception rod driving assembly; the interception rod driving assembly is used to drive the lifting and lowering of the interception rod 7; when the interception rod 7 is lifted, the ship passes normally; when the interception rod 7 is lowered, the passage is closed.

[0068] The interception rod driving assembly in this embodiment includes: an electrically controlled rotor 6, a pulling cable wheel 702 and a pulling cable 701;

[0069] The electrically controlled rotor 6 is arranged on the outer wall of the anti-collision plate 4, and one end of the interception rod 7 is arranged on the electrically controlled rotor 6; the electrically controlled rotor 6 belongs to the existing technology, and its structural characteristics and principles are no longer repeated here; under the drive of the electrically controlled rotor 6, the interception rod 7 is lifted or lowered; a pulling cable wheel 702 is arranged at the edge of the upper end of the anti-collision plate 4, and the lower side of the pulling cable wheel 702 is directly opposite to the electrically controlled rotor 6; a pulling cable 701 is coiled on the pulling cable wheel 702, and the tail end of the pulling cable 701 is arranged on the interception rod 7; the pulling cable 701 provides auxiliary pulling gravity for the interception rod 7 to prevent the interception rod 7 from bending or even breaking under the action of its own gravity.

[0070] Example 5

[0071] Based on Example 4, the technical solution in Example 4 relies on human judgment on whether the ship can pass, and then decides whether it is necessary to start the electric-controlled rotor 6 to start interception; however, human judgment may make mistakes or there may be no time to make a judgment operation, and the ship is about to approach the bridge deck.

[0072] In this embodiment, two laser altimeters 9 are arranged at the upper edge of the pier clamp 1 through the support rod 901; the upper edge of the pier is close to the bottom of the bridge deck, so the distance from this position to the water surface is the distance from the bottom of the bridge deck to the water surface when the error is ignored.

[0073] One of the two laser altimeters 9 is used to measure the height between the bridge pier and the floating plate, and the other one measures the height of the ship; the laser altimeter 9 is connected to the control system for communication, and the control system is connected to the electric rotor 6 of the interception rod drive assembly for communication; the control system is integrated with a microprocessor; the two laser altimeters 9 respectively monitor and collect the distance between the water surface and the bottom of the bridge deck and the height of the approaching ship in real time; after the two collected information are fed into the microprocessor by the laser altimeter 9, the microprocessor performs data processing and comparison. When the height of the ship is higher than the distance between the water surface and the bottom of the bridge deck, it means that the ship cannot pass under the bridge deck normally at this time; at this time, the microprocessor sends an instruction to the electric rotor 6, so that the electric rotor 6 drives the interception rod 7 to descend, intercepting the navigation channel, and preventing the ship from forcibly passing through and hitting the bridge deck.
