An automatic inflatable dock fender

Abstract

The invention discloses an automatic inflation type dock fender. The automatic inflation type dock fender comprises a first air sac and a second air sac, wherein the first air sac comprises a first inflating sac; an impingement baffle is mounted in the first inflating sac, and is connected with a piston rod; a plurality of sets of first springs are arranged in the first inflating sac; a connecting plate is arranged outside the first inflating sac, and is connected with one end of a ventilation cylinder; a piston is mounted in the ventilation cylinder, and is connected with a second spring; the second spring is connected with the second air sac; the other end of the of the ventilation cylinder is connected with the second air sac; a one-way valve is arranged at the connector of the second air sac and the ventilation cylinder; and an air valve is arranged on the second air sac. According to the automatic inflation type dock fender disclosed by the invention, the impact force of a hull to a fender is utilized to compress air into the inflating air sac, so that the purpose of automatically inflating for buffering and energy absorption is achieved; besides, the buoyancy effect is utilized to drive a rod piece to move, so that pulling force to the fender in a direction in which the fender is away from the hull is generated, and counter force is greatly reduced; and compared with a conventional fender, the automatic inflation type dock fender has obvious advantages.

Description

technical field [0001] The invention relates to an automatic inflatable dock fender and belongs to the field of ships. Background technique [0002] Wharf fender is an elastic buffer device installed on the wharf. It is mainly used to reduce the impact on the wharf when the ship is berthing or mooring, and to prevent or eliminate damage to the ship and the wharf. At present, there are many inflatable fenders. Rubber, polymer organic matter and other elastic materials are used for energy absorption. Due to the simple structure and mostly relying on the properties of the material itself, the energy absorption capacity is limited, the reaction force is large, and it needs to be replaced regularly for manual inflation. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an automatic inflatable dock fender, which uses the impact force of the hull on the fender to compress the air int...
