Height-adjustable ship anti-collision device

Abstract

A height-adjustable ship anti-collision device comprises a base plate used for being fixed to a ship board, an anti-collision air bag arranged on the base plate in a sliding mode and a control mechanism used for adjusting the height of the anti-collision air bag, a plurality of electromagnets distributed in parallel in the height direction of the base plate are arranged on the base plate, and a permanent magnet is fixed to the back of the anti-collision air bag. The anti-collision air bags can slide through cooperation of the permanent magnets and the electromagnets. The control mechanism comprises a control box, a floating ball arranged in the control box and a control panel fixed to the floating ball, a water inlet is formed in the bottom of the side wall of the control box, the floating ball can drive the control panel to slide in the height direction of the control box, and the end, away from the floating ball, of the control panel extends out of the control box and is matched with a control switch arranged in the base plate. The control switch controls power-on and power-off of the electromagnets so as to change the magnetic relation between the electromagnets and the permanent magnets, the control mechanism controls power-on and power-off of each electromagnet through the position change of the control panel, and therefore the height of the anti-collision air bag is adjusted to correspond to the height of the floating ball.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a height-adjustable anti-collision device for ships. Background technique [0002] When a ship is sailing, the hull is prone to collide with obstacles at sea, or collide with other ships, which can easily cause violent vibrations and even cause the hull to rupture. Therefore, anti-collision devices are generally installed on the sides of ships to reduce the vibration during collision and protect the ship. At present, the existing ship anti-collision devices mainly use rubber fenders, which can fully absorb the energy during collision. Generally, rubber fenders can be divided into two categories according to their structure: solid rubber fenders and floating rubber fenders. Solid rubber fenders are anti-collision equipment for wharf ships with an earlier application history and a wide range of applications. According to the force of the rubber fender, it can be divided into shear...

AI Technical Summary

Problems solved by technology

[0003] When the cargo capacity of the ship is different, the draft of the hull is different, but the existing anti-collision device can be fixed and the position is difficult to adjust

After the draft of the hull is reduced, the impact position is lower than the position of the anti-collision device, which cannot play the role of anti-collision
