[0002] Bridge pier collision prevention is an important measure to ensure the safety of bridge structures and smooth traffic. The collision risk faced by bridge piers mainly comes from ship collision. For bridges across rivers, lakes or oceans, ships may collide with bridge piers due to operational errors, loss of control, etc. during navigation. The collision may cause cracks, deformation, concrete peeling, etc. in the piers. The piers are important supporting structures of the bridge. Damage to them will weaken the overall bearing capacity of the bridge and affect the stability of the bridge.

The sliding clamp ring is used for the connecting rod to be inserted, so that the maintenance process is simple and convenient, and the maintenance construction efficiency is improved.

[0006] 2. This patent cannot perform non-contact collision avoidance, and cannot assist in adjusting the deviation direction of the ship after the ship collides with the bridge pier to prevent the ship from colliding with the bridge pier for the second time.

[0020] In order to better achieve the purpose of the present invention, the present invention also provides a method for an electromagnetic lossless anti-collision device for a bridge pier, comprising the following steps:

[0021] Step 1: When the ship starts to lose speed and hit the bridge pier, adjust the moving direction of the ship to make it as far away from the bridge pier as possible, adjust the right moving device so that the ship anti-collision device of the right moving device faces the fixed anti-collision device on the bridge pier, and the servo motor of the moving device driving assembly rotates to drive the gear to rotate. The rotation of the gear enables the special-shaped frame of the moving frame assembly of the moving device to move on the annular tube. The ship anti-collision device on the right side of the special-shaped frame faces the fixed anti-collision device on the bridge pier. The hydraulic cylinder of the locking assembly of the moving device is started to push the friction ring to the annular tube, so that the special-shaped frame is locked on the annular tube;

[0022] Step 2: by adjusting the left moving device, the hull stabilizing device of the left moving device is moved to a suitable position, the telescopic hydraulic cylinder of the hull stabilizing device is started, the output end of the telescopic hydraulic cylinder moves downward to drive the connecting plate to move downward, the connecting plate moves downward to drive the submersible motor and the propeller blade to move downward, and the operator observes the left and right deviation of the ship after the collision to adjust the position of the hull stabilizing device of the left moving device;

[0023] Step 3: Start the first electromagnet and the second electromagnet through an external controller. The magnetism of the first electromagnet and the second electromagnet in opposite directions is mutually repulsive. When the ship approaches the bridge pier, the ship is decelerated by the mutually repulsive magnetism of the first electromagnet and the second electromagnet.

[0024] Step 4: When the ship does not hit the bridge pier head-on, after the ship hits and slows down, the ship will deviate to the left or right. The specific direction of deviation depends on the direction of the ship hitting the bridge pier. The operator observes the direction of the ship hitting the bridge pier in advance to adjust the position of the hull stabilization device of the left moving device. At this time, the submersible motor of the hull stabilization device is started. Since it is not a contact collision, the ship is still a certain distance away from the bridge pier. The output shaft of the submersible motor rotates to drive the propeller blades to rotate, and the ship is straightened to avoid the ship deviating after the collision and hitting the bridge pier again;

[0025] Step 5: In addition, the water level sensor of the fixed anti-collision device repelling assembly detects the distance between the device and the water level, and transmits an electrical signal to the controller of the pier. The controller of the pier controls the screw lift of the fixed anti-collision device lifting assembly to start, driving the second electromagnet to move up and down on the dovetail guide rail, so that the second electromagnet is always above the water surface.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention detects the distance between the water level sensor of the fixed anti-collision device repulsion component and the water level, and transmits an electrical signal to the controller of the pier. The controller of the pier controls the start of the screw elevator of the fixed anti-collision device lifting component, driving the second electromagnet to move up and down on the dovetail guide rail, so that the second electromagnet is always above the water surface, and the repulsion component and the lifting component are both installed separately. When damaged, only the damaged repulsion component or lifting component can be replaced, which is conducive to rapid maintenance and does not occupy too many waterways.

[0027] The first electromagnet and the second electromagnet are started by an external controller, and the magnetism of the first electromagnet and the second electromagnet in opposite directions is mutually repulsive. When the ship approaches the bridge pier, the mutually repulsive magnetism of the first electromagnet and the second electromagnet slows down the ship and performs contactless collision avoidance, so that there is no need to replace the ship's anti-collision device and the fixed anti-collision device after a collision occurs.

[0028] The output end of the telescopic hydraulic cylinder moves downward, driving the connecting plate to move downward, and the connecting plate moves downward, driving the submersible motor and propeller blades downward. The operator observes that the ship deviates left and right after the collision and adjusts the position of the hull stabilizing device of the left moving device. At this time, the submersible motor of the hull stabilizing device is started. Since it is not a contact collision and the ship is still a certain distance away from the pier, the output shaft of the submersible motor rotates, driving the propeller blades to rotate and straighten the ship to avoid the ship deviating from the collision and hitting the pier again.

A ship anti-collision device 4 for ship anti-collision is installed on the right side of the right moving device 3. A ship stabilizing device 5 is installed on the rear side of the left moving device 3. A bridge pier 2 is arranged on the right side of the annular circular tube 1. A plurality of fixed anti-collision devices 6 are installed on the bridge pier 2. The annular circular tube 1 is fixedly installed on the outside of the ship.

[0043] The moving device 3 includes: a moving frame assembly, a locking assembly and a driving assembly. The moving frame assembly is installed on the annular circular tube 1, the two locking assemblies are installed on the upper side of the moving frame assembly, and the driving assembly is installed on the lower side of the moving frame assembly.

[0044] When the ship begins to lose speed and hit the bridge pier 2, the moving direction of the ship is adjusted to make it as far away from the bridge pier 2 as possible. By adjusting the right-side moving device 3, the ship anti-collision device 4 of the right-side moving device 3 is facing the fixed anti-collision device 6 on the bridge pier 2. The operator observes the left and right deviation of the ship after the collision to adjust the moving position of the hull stabilizing device 5 of the left-side moving device 3. After the ship hits the bridge pier 2, the ship slows down. When the ship does not hit the bridge pier 2 directly from the front, the ship will deviate to the left and right directions after the collision and deceleration. The deviation of the ship is adjusted by the hull stabilizing device 5 so that it will not deviate and hit the bridge pier 2 a second time.

A plurality of metal rollers 32 are rotatably connected to the special-shaped frame 31 via a rotating shaft, which is conducive to the special-shaped frame 31 being able to withstand a large impact force while moving on the two annular circular tubes 1.

[0046] The metal rollers 32 on the special-shaped frame 31 rotate, so that the special-shaped frame 31 can move quickly on the two annular tubes 1, which is conducive to the special-shaped frame 31 being able to withstand a large impact force while moving on the two annular tubes 1.

[0047] The locking assembly includes: a hydraulic cylinder 33 and a friction ring 34. A plurality of the hydraulic cylinders 33 are fixedly mounted on the upper side of the special-shaped frame 31. A friction ring 34 is fixedly mounted on the output end of each of the hydraulic cylinders 33. The friction ring 34 can be made of rubber material to increase friction and prevent the special-shaped frame 31 from sliding when impacted.

[0048] The hydraulic cylinder 33 is activated to push the friction ring 34 to the annular tube 1, so that the special-shaped frame 31 is locked on the annular tube 1, which is beneficial to increase the friction force and prevent the special-shaped frame 31 from sliding when impacted.

The gear 37 and the arc-shaped rack 35 are meshed with each other. The servo motor 36 is configured as a waterproof servo motor 36.

[0050] The rotation of the servo motor 36 of the driving assembly of the mobile device 3 drives the gear 37 to rotate. The rotation of the gear 37 enables the special-shaped frame 31 of the mobile frame assembly of the mobile device 3 to move on the annular tube 1, which is conducive to quickly driving the special-shaped frame 31.

The first electromagnet 41 is fixedly installed on the right side of the special-shaped frame 31. The first buffer plate 42 is fixedly installed on the right side wall of the first electromagnet 41. The first buffer plate 42 is used to buffer possible contact collisions between the first electromagnets 41. The first electromagnet 41 is electrically connected to an external controller.

[0052] Embodiment 2: Figure 4 and Figure 7 As shown, as a preferred embodiment of the present invention, the hull stabilizing device 5 includes: a telescopic hydraulic cylinder 51, a connecting plate 52, a submersible motor 53 and a propeller blade 54, a plurality of the telescopic hydraulic cylinders 51 are fixedly mounted on the rear side of the special-shaped frame 31 of the moving frame assembly of the left moving device 3, the connecting plate 52 is fixedly mounted on the output end of the telescopic hydraulic cylinder 51, the submersible motor 53 is fixedly mounted on the lower side of the connecting plate 52 through a motor bracket, and the propeller blade 54 is fixedly mounted on the output shaft of the submersible motor 53.

[0053] The output end of the telescopic hydraulic cylinder 51 moves downward, driving the connecting plate 52 to move downward. The connecting plate 52 moves downward, driving the submersible motor 53 and the propeller blades 54 to move downward. The operator observes that the ship deviates left and right after the collision and adjusts the position of the hull stabilizing device 5 of the left movable device 3. At this time, the submersible motor 53 of the hull stabilizing device 5 is started. Since it is not a contact collision, the ship is still a certain distance away from the pier 2. The output shaft of the submersible motor 53 rotates, driving the propeller blades 54 to rotate, and straightening the ship to avoid the ship from deviating from the collision and hitting the pier 2 again.

[0057] The water level sensor 12 of the repulsion component of the fixed anti-collision device 6 detects the distance between the device and the water level and transmits an electrical signal to the controller of the pier 2. The controller of the pier 2 controls the screw elevator 10 of the lifting component of the fixed anti-collision device 6 to start, driving the second electromagnet 11 to move up and down on the dovetail guide rail 8, so that the second electromagnet 11 is always located above the water surface, and the repulsion component and the lifting component are installed separately. When damaged, only the damaged repulsion component or lifting component can be replaced, which is conducive to rapid maintenance and does not occupy too many waterways.

[0058] The first electromagnet 41 and the second electromagnet 11 are started by an external controller. The magnetism of the first electromagnet 41 and the second electromagnet 11 in opposite directions is mutually repulsive. When the ship approaches the pier 2, the mutually repulsive magnetism of the first electromagnet 41 and the second electromagnet 11 slows down the ship and performs contactless collision avoidance, so that there is no need to replace the ship anti-collision device 4 and the fixed anti-collision device 6 after a collision occurs.

[0060] Step 1: When the ship starts to lose speed and hit the pier 2, the moving direction of the ship is adjusted to make it as far away from the pier 2 as possible. By adjusting the right moving device 3, the ship anti-collision device 4 of the right moving device 3 faces the fixed anti-collision device 6 on the pier 2. The servo motor 36 of the driving assembly of the moving device 3 rotates to drive the gear 37 to rotate. The gear 37 rotates so that the special-shaped frame 31 of the moving frame assembly of the moving device 3 can move on the annular tube 1. The ship anti-collision device 4 on the right side of the special-shaped frame 31 faces the fixed anti-collision device 6 on the pier 2. The hydraulic cylinder 33 of the locking assembly of the moving device 3 is started to push the friction ring 34 to the annular tube 1, so that the special-shaped frame 31 is locked on the annular tube 1;

At this time, the submersible motor 53 of the hull stabilizing device 5 is started. Since it is not a contact collision, the ship is still a certain distance away from the pier 2. The output shaft of the submersible motor 53 rotates to drive the propeller blades 54 to rotate, and the ship is straightened to avoid the ship from deviating after the collision and hitting the pier 2 again.

[0064] Step 5: In addition, the water level sensor 12 of the repulsion component of the fixed anti-collision device 6 detects the distance between the device and the water level, and transmits an electrical signal to the controller of the pier 2. The controller of the pier 2 controls the screw lift 10 of the lifting component of the fixed anti-collision device 6 to start, driving the second electromagnet 11 to move up and down on the dovetail guide rail 8, so that the second electromagnet 11 is always above the water surface.
