Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy equipment, and in particular relates to a self-floating CRF bridge pier anti-ship collision device based on aluminum composite anti-collision material. Background Art

[0002] With the development of transportation, more and more bridges are built, which has brought great convenience to our land transportation and greatly improved the convenience of land transportation. However, this has also brought certain impacts on our water shipping. Ships often collide with bridges. This makes our water transportation, how to avoid the occurrence of ships colliding with bridges is a problem we need to face.

[0003] The inner side of the current anti-collision device will collide with the bridge pier, and then the anti-collision device and the bridge pier are regarded as an integral structure to resist the impact of the ship, so that the anti-collision device can better transmit the impact force of the ship to the base part of the bridge pier, and use the strong structural strength of the bridge pier itself to jointly resist the impact. However, when there is no ship approaching for collision, the water flow will continue to flush the bridge pier and the anti-collision device. If the anti-collision device fits tightly against the bridge pier, the water flow will be hindered when passing through, generating turbulence and vortices. Such turbulence and vortices will increase the flushing force of the water flow on the bridge pier and the anti-collision device, and accelerate the erosion of the structure, especially in seawater environments, which will accelerate the corrosion of metal parts. Leaving a gap allows the water flow to pass relatively smoothly, reducing the adverse impact of the water flow. This creates contradictions in the use of the anti-collision device and cannot meet actual use needs well. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting up the inner supporting mechanism, the limit locking mechanism and the laser detection mechanism, it is possible to leave a gap between the anti-collision device and the bridge pier when there is no risk of ship collision, so as to avoid the anti-collision device and the bridge pier being closely fitted, thereby preventing the water flow from being obstructed when passing through, generating turbulence and vortexes, and ensuring that the water flow can pass relatively smoothly. When there is a risk of ship collision, the inner side of the anti-collision device is made to collide with the bridge pier, and the anti-collision device and the bridge pier are regarded as an integral structure to resist the impact of the ship. The anti-collision device can better transmit the impact force of the ship to the foundation part of the bridge pier, and use the strong structural strength of the bridge pier itself to jointly resist the impact. It can automatically adjust according to the use requirements and has better adaptability.

[0022] 2. The recoil protection mechanism can convert the ship impact force received by the inner supporting mechanism into a recoil force, which not only has a further buffering and protective effect, but also the generated recoil force can assist in pushing the ship away, reduce the impact intensity, and provide better protection.

[0023] 3. By setting up the outer protection mechanism for turning the heading, the clamping connection mechanism, and the laser detection mechanism, the outer side of the anti-collision ring can be provided with enhanced protection. When the ship collides with the anti-collision ring, the rotating guide cylinder is used to provide a guiding force for the ship to turn the ship's heading, reduce the energy exchange and damage between the ship and the anti-collision device, and reduce the impact force of the direct collision. When there is no danger of ship collision, the rotating guide cylinder is fixed to avoid excessive friction and collision of the internal mechanical connection parts of the rotating guide cylinder due to the shaking caused by wind and waves, which will increase the rotation resistance and affect the performance of the rotating guide cylinder.

[0024] 4. The automatic lubricating oil adding mechanism can convert the impact force caused by the approach of the ship into the power for adding lubricating oil, so as to realize the automatic addition of lubricating oil to the rotating guide cylinder when there is a risk of ship collision. Then, when the ship hits the rotating guide cylinder, the rotating guide cylinder can rotate better, making the navigation performance of the turning ship more stable.

[0044] The laser detection mechanism 8 is fixedly mounted on the anti-collision ring 1. The laser detection mechanism 8 includes a protective shell 81, in which a flip plate 82 is rotatably connected, and a laser radar 83 is fixedly mounted on the flip plate 82. A flip motor 84 for driving the flip plate 82 to rotate is fixedly mounted on the outer wall of the protective shell 81. An operating cavity 85 is provided inside the four ends of the flip plate 82.

A plug-in groove 87 that matches the plug-in rod 86 is provided on the inner wall of the protective shell 81. An end of the plug-in rod 86 located in the operating cavity 85 is fixedly connected to a pushing plate 88, and a plug-in spring 89 that is sleeved on the outside of the plug-in rod 86 is fixedly connected to the pushing plate 88 and the opposite side of the pushing plate 88 and the operating cavity 85. A suction permanent magnet plate 810 is fixedly mounted on the side of the pushing plate 88 away from the plug-in rod 86, and a suction electromagnetic plate 811 that is arranged opposite to the suction permanent magnet plate 810 is fixedly mounted on the inner wall of the operating cavity 85.

[0045] The PLC controller is electrically connected to the limit locking mechanism 3, the clamping connection mechanism 6 and the laser detection mechanism 8 respectively.

[0046] The operating principle of the present invention is described as follows: the laser radar 83 is used to detect in real time whether there is a ship approaching around the anti-collision circle 1. When the laser radar 83 detects that the distance of the ship approaching around the anti-collision circle 1 is too close to reach the threshold, the PLC controller first controls the dual-axis motor 33 to operate, and the dual-axis motor 33 drives the two rotating screws 34 to rotate. Through the threaded sleeve effect of the rotating screw 34 and the push-pull plate 35, the push-pull plate 35 cooperates with the push-pull rod 36 to drive the two L-shaped locking plates 31 to move back to each other, so that the L-shaped locking plate 31 releases the limit lock on the fixed plate 22, and then under the action of the buffer spring 25, the buffer rubber block 23 is further moved, so that the buffer rubber block 23 is in contact with the bridge pier, so that there is no gap between the inner supporting mechanism 2 and the bridge pier, thereby improving the subsequent anti-collision performance;

[0047] At the same time, the PLC controller controls the electric telescopic rod 62 to move, and the electric telescopic rod 62 drives the L-shaped moving plate 63 to move, and the L-shaped moving plate 63 drives the multiple T-shaped clamping blocks 64 to move, so that the T-shaped clamping blocks 64 are separated from the limited clamping connection with the L-shaped clamping plate 65, thereby releasing the limited fixation of the mounting plate 52, and under the action of the compensation spring 55, the mounting plate 52 pushes the rotating guide cylinder 53 to move outward, so that the rotating guide cylinder 53 moves to the anti-collision use position;

[0048] When the ship approaches and the water flow generates an impact force on the rotating guide cylinder 53, the rotating guide cylinder 53 drives the mounting plate 52 to move back and forth away from the anti-collision ring 1. When the mounting plate 52 moves close to the anti-collision ring 1, the mounting plate 52 will synchronously press on the force plate 74, and the force plate 74 cooperates with the force rod 73 to drive the pressurizing piston plate 72 to move in the adding shell 71 to overcome the elastic force of the return spring 75, and then the lubricating oil in the adding shell 71 is transported to the lubricating oil adding port of the rotating guide cylinder 53 through the adding pipe 76, and the rotating guide cylinder 53 is automatically added with lubricating oil. When the mounting plate 52 moves away from the anti-collision ring 1, the force plate 74 is not squeezed by pressure, and then the force plate 74 and the pressurizing piston plate 72 are moved back under the action of the return spring 75, and then the lubricating oil in the lubricating oil storage cylinder 77 is replenished into the adding shell 71 again through the replenishing pipe 78, so as to realize the automatic addition of lubricating oil and make full preparations for the collision of subsequent ships.

[0049] When the ship comes into contact with the entire anti-collision device, the laser radar 83 detects that the ship's approaching distance has reached the limit, and the PLC controller controls the power supply device to supply power to the suction electromagnetic plate 811. The suction electromagnetic plate 811 is energized to generate a magnetism opposite to the suction permanent magnet plate 810, thereby generating an attraction to the pushing plate 88, thereby overcoming the elastic force of the plug spring 89 to pull the plug rod 86 out of the plug slot 87, and releasing the limit lock between the flip plate 82 and the protective shell 81. The PLC controller then controls the flip motor 84 to drive the flip plate 82 to rotate 180 degrees, and flips the laser radar 83 into the protective shell 81 for protection. At this time, the PLC controller controls the power supply device to cut off the power supply to the suction electromagnetic plate 811, so that the pushing plate 88 loses its attraction. Under the pullback action of the plug spring 89, the plug rod 86 is inserted into the plug slot 87 again to limit the flip plate 82.

[0050] When a ship collides with the rotating guide cylinder 53, the rotating guide cylinder 53 provides a guiding force to the ship, turns the ship's course, reduces the energy exchange and damage between the ship and the anti-collision device, and provides a first-level buffering protection force through the provided compensation spring 55. The remaining impact force acts on the buffer spring 25, the buffer rubber block 23 and the compressed air bag 41 through the anti-collision ring 1, and performs multi-level buffering protection to provide better anti-collision protection.

[0051] When the compressed airbag 41 is squeezed due to the impact force of the ship, the air in the compressed airbag 41 will be ejected through the recoil pipe 43 and the jet head 44, thereby forming a reverse impact force in the water, providing a reverse thrust to the ship, helping the ship to better change its course and reduce the damage caused by impact and collision.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
