A ship mast retractable structure

Abstract

The invention discloses a ship mast retraction structure and aims to overcome the defect that a mast is easy to collide when a ship passes through a bridge hole to result in accidents. After the mastcollides with the bridge hole, the mast can be automatically dumped, the mast is not easy to be damaged to result in accidents, the mast is convenient to return after the mast is dumped and passes through the bridge hole; Regardless of colliding with the bridge hole in the advancing process or colliding with the bridge hole in the retreating process, the upper section of the mast can rotate downwards to reduce the height so that the ship can pass through the bridge hole; When the ship does not pass through the bridge hole in the forward direction, one end of the impact rod firstly impacts on the bridge hole, an instant impact force drives the mast to rotate, the impact rod deflects to reduce the height of the mast, so that the mast can smoothly pass through the bridge hole.

Description

technical field [0001] The invention relates to the technical field of ships, more specifically, it relates to a ship mast retractable structure. Background technique [0002] The mast is generally installed at the highest point of the ship and is used to install radar, navigation signal lights and communication antennas, etc. It is a very important safety facility when the ship is sailing. When a ship passes under a bridge erected on the water, due to the different heights of the bridge holes, the mast on the ship may collide with the bridge and damage the mast. In order to avoid the collision, it is necessary to lower the mast in advance and lower the height to ensure the safety of the ship. pass. However, every time you pass through the bridge hole, you must first judge whether the height of the bridge hole allows the mast to pass safely. If you cannot pass safely, you need to put down the mast, which increases the workload, and is also prone to negligence or misjudgment...

However, every time you pass through the bridge hole, you must first judge whether the height of the bridge hole can allow the mast to pass safely. If you cannot pass safely, you need to put down the mast, which increases the workload, and is also prone to negligence or misjudgment, resulting in collision accidents, resulting in major property losses. , especially when the ship sails at night, this problem is even more prominent
