Example 1: a liquid press and berth collision avoidance system, hydraulic pressure berth collision avoidance system's major structure be box 1, the box is stainless steel, box 1's one end is provided with protection device 10, this protection device 10 is the bumper in this implementation, specifically, the bumper can set up in arbitrary one end of box, when using for the bumper with towards boats and ships direction can, make the bumper be located hydraulic pressure berth collision avoidance system top.
The bumper 10 is connected to a hydraulic fender system 20, and the hydraulic fender system 20 is fixed to the box 1. The hydraulic fender system 20 includes a hydraulic cylinder 201 and an oil tank 202; the hydraulic cylinder 201 comprises a piston rod 2011 connected to the middle of the bumper and a spring 2012 arranged inside the hydraulic cylinder 201 and connected to the piston rod 2011, the spring in the hydraulic cylinder providing a force that moves the piston rod back to the initial position when the vessel leaves the quay. When the bumper is extruded, the bumper extrudes the piston rod connected with the bumper, so that the bumper becomes a hydraulic energy-absorbing bumper capable of stretching back and forth. An outlet of the oil tank 202 is connected with an inlet of a first check valve 203, an outlet of the first check valve 203 is communicated with an oil path inlet of the hydraulic cylinder, an inlet of the oil tank 202 is connected with an inlet of a second check valve 204, and an outlet of the second check valve 204 is connected with an oil path outlet of the oil tank 202.
A throttle valve 205 is arranged between the second check valve 204 and the oil path outlet of the oil tank 202; one end of the throttle valve 205 is connected to the outlet of the second check valve 204, and the other end of the throttle valve 205 is connected to the oil passage outlet of the oil tank 202.
The utility model discloses a hydraulic pressure berth collision avoidance system still is provided with alarm system 30, and alarm system 30 includes siren 301, the treater 302 of being connected with siren 301 electricity and the power 303 of being connected with treater 302, and treater 302 is the singlechip in this embodiment.
The utility model discloses the working method of device: when the ship turns on the power switch, the alarm system enters a working state, the single chip microcomputer of the microcomputer control system continuously sends a high-frequency ranging signal to the range finder, the range finder immediately transmits measured data back to the single chip microcomputer, and the single chip microcomputer starts the alarm to send an alarm to a crew and extends out of the hydraulic berthing collision avoidance system when the ship speed exceeds a certain value (the value is the preset minimum distance from the shore when the ship is berthed) through calculation and judgment comparison.
The bumper in the extended hydraulic berthing anti-collision system is positioned at the top end of the whole hydraulic berthing anti-collision system, and the bumper is inevitably contacted with a collision object ship firstly after being extended, and at the moment, under the extrusion of the bumper, the hydraulic cylinder 201 in the hydraulic fender system 20 retracts after collision to form a buffering process so as to protect the ship body.
When the ship is berthed, the piston rod of the hydraulic cylinder 201 collides, the collision pressure causes the piston inside to move inwards to extrude the hydraulic oil in the hydraulic cylinder, meanwhile, the spring is compressed, the hydraulic oil in the hydraulic cylinder barrel is increased due to the movement pressure of the piston, the hydraulic cylinder is extruded by the piston rod, the hydraulic oil in the hydraulic cylinder flows out, a reverse hydraulic oil flow path is formed in the flow path where the second check valve is located, when the pressure of the reverse oil outlet exceeds a certain value, the second one-way valve is opened, the hydraulic oil in the cylinder barrel of the hydraulic cylinder enters the oil tank through the throttle valve and the second one-way valve, the movement of the piston rod for compressing the hydraulic oil consumes a large amount of kinetic energy, the kinetic energy comes from impact energy generated when the ship is impacted, the energy is consumed by the motion of the piston, and the impact energy received by the ship is reduced, so that the ship is protected from being damaged by the impact energy;
in a non-working state, the bumper is retracted to a normal position as a buffer, the piston rod returns to the original position under the action of the reset spring, the pressure is reduced, and hydraulic oil in the oil tank enters the cylinder barrel of the hydraulic cylinder through the first check valve to supplement the pressure, so that the whole process is completed. When the hydraulic oil passes through the second check valve, the first check valve is always closed. Similarly, when the hydraulic oil passes through the first check valve, the second check valve is closed.
The throttle valve and the second one-way valve are connected to form a one-way throttle valve, and the flow and the pressure can be changed by adjusting a flow adjusting hand wheel on the throttle valve.
The utility model discloses a striking energy can be absorbed high-efficiently in the conversion of energy, the reducible maintenance cost of cyclic utilization of hydraulic oil, and can improve the limit point that hydraulic buffer absorbed energy through the size that changes the pneumatic cylinder, effectively promote the safety of berthing of boats and ships.
