The specific working process of the invention is as follows: when the device is in an initial state, the extending end of the electric pull rod 6 extends out to enable gas in the first cavity 4 to be discharged, the first cavity 4 and the second cavity 9 can sink into water under the action of self weight, the distance induction switch 17 enables the distance induction switch 17 to be arranged above the water surface under the action of the floating plate 16, when a ship goes across a bridge pier and is close to a pier to a certain degree, the distance induction switch 17 is opened to enable a plurality of groups of electric pull rods 6 to be electrified simultaneously, the electric pull rods 6 are electrified to enable the extending ends to retract, in the process, the piston 5 moves downwards along the inner wall of the first cavity 4, outside air enters the first cavity 4 from the air inlet pipe 8, meanwhile, water in the first cavity 4 is discharged from the water discharge hole 7, at the moment, the buoyancy of the first cavity 4 is increased and is solid, the device floats out of the water surface, at the moment, the inclined plane of the second cavity 9 close to the lower part of the ship body extrudes the ship body, and enables the second cavity 9 to drive the whole device to incline, at the moment, the first pressure springs 18 in the first elastic supports 2 at the upper end of the vertical pipe 1 far away from the ship body are compressed, the first pressure springs 18 in the first elastic supports 2 at the lower end of the vertical pipe 1 near the ship body are compressed, the compressed first pressure springs 18 have rebound tendency and elastic potential energy, and after the second roller 11 contacting the ship body is compressed, the second telescopic support is compressed, at the moment, the motor in the area rotates, the belt wheel 21 drives the inner gear ring 15 to rotate, the inner gear ring 15 drives the gear shaft 14 and the second bevel gear 13 to engage the first bevel gear 12 to drive the second roller 11 to rotate, the second roller 11 rotates to reversely drive the ship body to the outside, when the ship body leaves the device a little, the first cavity 4 and the second cavity 9 are driven to reset upwards by buoyancy, in the process, the second roller 11 is always pressed at the lower end of the ship body, and the state disappears after the ship body is completely pushed away, first cavity 4 and second cavity 9 float on the surface of water this moment and first cavity 4 and second cavity 9 are in coaxial state with the pier, leave the back when the hull, apart from inductive switch 17 not moving for electric pull rod 6, electric pull rod 6 loses the power supply this moment, have gradually the trend of sinking to the bottom under the action of gravity of this device, the air in first cavity 4 is evacuated gradually at this device whereabouts in-process simultaneously, realize that first cavity 4 and second cavity 9 fall to the bottom, wait to move down the hull and carry out the anticollision once more after being close to.
Compared with the traditional equipment, the device has the following advantages:
1. this device is when not using first cavity 4 and second cavity 9 sink into the aquatic for only leave a floating plate on the surface of water and take a distance inductive switch 17, take up an area of the space little, the passageway of going a ship is big, makes the line more high-efficient, and buffer stop arranges in under water simultaneously, can effectively place lawless persons 'act as a theft, can also reduce buffer stop's wearing and tearing damage simultaneously.
2. This device uses buoyancy as promotion power, make 6 stimulate piston 5 downwards at electric pull rod, first cavity 4 can stretch out the surface of water fast after getting angry, this device rises to generate a unrestrained from inside to outside after the surface of water, this wave flower also can effectually block the hull and be close to the pier, second cavity 9 rises to cause this device slope with the tip of hull contact after the surface of water by the extrusion simultaneously, a plurality of first pressure springs 18 have the trend that makes standpipe 1 reset this moment, a plurality of second gyro wheels 11 drive hulls of motor drive are reverse to be left simultaneously, after leaving a bit, the reset action of first gyro wheel 3 and first pressure spring 18 is down, can make this device of slope reset a bit gradually, this in-process, make second gyro wheel 11 extrude the hull lower extreme all the time and can leave until the hull completely, this device finally can realize and pier coaxial state.
3. This device adopts the mode of early warning, treats that the hull initiatively attacks when being close enough to the pier for buffer stop initiatively rises, and initiatively realizes the rotation of second gyro wheel 11, realizes pushing the hull open reversely, and whole process hull contactless pier just can be putd aside the hull, makes whole collision avoidance process can be more high-efficient and can protect pier and row ship in the at utmost.
The invention has novel concept, ingenious structure and strong practicability, and effectively solves the problems that the diameter of a pier is increased and a ship passage is narrowed because bridge anti-collision equipment is fixed or placed on the water surface at the present stage, and the abrasion between the pier and the anti-collision equipment is increased.
