Ship navigation anti-collision device

Abstract

The invention relates to the technical field of navigation ships and discloses a ship navigation anti-collision device which comprises a ship base body and an anti-collision base plate arranged outside the ship base body. Fixing plates are fixedly connected to the two sides of the bottom of the ship base body respectively, bottom surfaces of the fixing plates are fixedly provided with positioningboxes which are evenly distributed, and supporting rods are movably arranged in the positioning boxes. According to the ship navigation anti-collision device, the anti-collision base plate for protecting the ship base body is arranged outside the ship base body so that substances or objects in the ship base body and seawater and reefs on a shore can be prevented from directly contacting with the ship base body, and damage of the ship base body is avoided; and meanwhile, an extrusion spring is used for being matched with a positioning box, a supporting rod, an extrusion plate and a telescopic spring which are arranged between the ship base body and the anti-collision base plate and used for buffering, a force generated when the ship base body is impacted can be buffered, the anti-collisionbase plate is prevented from being directly damaged, a service life of the device is prolonged, and the ship base body is prevented from being directly impacted and damaged.

Description

technical field [0001] The invention relates to the technical field of navigation ships, in particular to a ship navigation anti-collision device. Background technique [0002] A ship is a means of transportation that can sail or berth in waters for transportation or operation. It has different technical performance, equipment and structural types according to different use requirements. A ship is composed of many parts. According to the functions and uses of each part, it can be It is comprehensively summarized into three parts: hull, ship power device, and ship electrical equipment, and the ship power device includes: propulsion device-the main engine drives the propeller through the reduction device and the transmission shaft system; auxiliary mechanical equipment for the operation of the propulsion device and Systems, such as fuel pumps, lubricating oil pumps, cooling water pumps, heaters, filters, coolers, etc.; ship power stations, which provide power for ship deck mac...

AI Technical Summary

Problems solved by technology

[0003] When existing ships are navigating or docking, the middle and lower positions of the hull are often in direct contact with seawater or the shore. When substances or objects in seawater and reefs on the shore directly contact the ship, it is easy to cause damage to the hull of the ship. Damage will affect its service life. A small number of ships have anti-collision devices, but after long-term use, the elasticity of the springs they use tends to decrease, which affects their anti-collision effects. For this reason, we propose a ship navigation anti-collision device
