Anti-collision device for ship navigation

Abstract

The invention relates to the technical field of nautical ships, and discloses a ship nautical anti-collision device, which includes a ship base body and an anti-collision base plate arranged outside the ship base body, the two sides of the bottom of the ship base body are respectively fixedly connected with fixing plates, and the fixing plates There are evenly distributed positioning boxes on the bottom surface of the fixed sleeve, and the internal movable sleeve of the positioning box is equipped with support rods. The ship navigation anti-collision device can prevent the ship base from directly contacting the ship base with substances or objects in the seawater and reefs on the shore by providing an anti-collision substrate outside the ship base to cause damage to the ship base. At the same time, the extrusion spring is used to cooperate with the positioning box, support rod, extrusion plate and telescopic spring used for buffering between the ship base and the anti-collision base plate, which can buffer the force when hitting the ship base and prevent it from directly causing the anti-collision base plate. damage, prolonging the service life of the device, while avoiding direct impact damage to the ship substrate.

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
