Self-adjusting ship anti-collision energy absorption device

Abstract

The invention discloses a self-adjusting ship anti-collision energy absorption device which structurally comprises an energy absorption buffer structure, a shell, a flexible anti-collision device andbuckle strips. The flexible anti-collision device is mounted in the shell and is in mechanical connection with the energy absorption buffer structure mounted outside the shell, the buckle strips are vertically mounted on upper and lower sides of the shell, where the energy absorption buffer structure is mounted, the energy absorption buffer structure is provided with a backpressure rebound structure, a synchronous chain structure, a transmission pressure rod structure and a device structure, the backpressure rebound structure is mounted in the device structure and is in mechanical connection with the flexible anti-collision device through the transmission pressure rod structure, and the device structure is connectively fixed with the flexible anti-collision structure as well. The energy absorption buffer structure and the flexible anti-collision device are adopted, the internal space of the device is enlarged, structure layout is changed, low structural strength is achieved, anti-collision performance is enhanced, energy absorption can be adjusted automatically according to strength, and the function of secondary energy absorption is achieved.

Description

technical field [0001] The invention relates to the field of ship anti-collision, in particular to an automatically adjustable ship anti-collision energy-absorbing device. Background technique [0002] With the continuous development of transportation, the number of ships at sea increases, and ship collision accidents occur frequently. Generally, the speed of the two ships is different at sea. After the collision, the strength of the ship's anti-collision structure is low and the bearing capacity is low. , water enters through holes in the hull, the liquid level of the ballast tank and fresh water tank changes, the liquid level of the oil tank drops, water enters the ship, sinks the ship, and causes safety accidents. Therefore, the main problems of the existing ship anti-collision structure are: 1. .The structural strength is low, and the bearing capacity is low. If the stiffness of the anti-collision structure is increased to improve its anti-collision force, it will affect...

Therefore, the main problems of the existing ship anti-collision structure are: 1. .The structural strength is low, and the bearing capacity is low. If the stiffness of the anti-collision structure is increased to improve its anti-collision force, it will affect the operation of the ship; 2. It cannot be adjusted independently, and the secondary energy absorption
