Bottom sealing plate of telescopic side thrust device

Abstract

The invention relates to a bottom sealing plate of a telescopic side thrust device. The bottom sealing plate is composed of a bottom plate and knee plates. The telescopic side thrust device comprises a telescopic device, a thrust screw propeller is arranged at the lower end of the telescopic device, and a screw propeller protecting cover is arranged on the periphery of the thrust screw propeller. The bottom plate is installed horizontally, the knee plates are installed vertically, the upper ends of the knee plates are fixed to the bottom of the screw propeller protecting cover, and the lower ends of the knee plates are welded to the bottom plate. An outer plate is arranged on a ship bottom plate, an open hole is formed in the outer plate, the bottom sealing plate penetrates in the open hole when vertically moving along with the telescopic device, and the streamline of the bottom plate is matched with the streamline of the position, at the open hole, of the outer plate. The shape of the bottom plate is adapted to that of the open hole of the outer plate. The bottom sealing plate can reduce eddy resistance generated at a cave of the open hole of the outer plate when a ship sails normally, and energy consumption of the ship is reduced.

Description

technical field [0001] The invention relates to a ship component, in particular to a bottom sealing plate of a retractable side thruster. Background technique [0002] The retractable side thruster of the ship plays a power role on the ship. The existing retractable propulsion device includes a telescopic device, which can move up and down. The bottom end of the telescopic device is equipped with a propulsion propeller and a propeller protective cover. The retractable side thruster will extend out of the bottom of the ship to work when the ship needs to be boosted, power failure or dynamic positioning state. If it encounters an impact object in seawater, it will cause a certain impact on the propeller protective cover. If there is an ocean Garbage exists, it may be suspended on the propulsion propeller, forming a great resistance to the propulsion device. When the retractable side thruster is in the working or non-working state of the side thruster, the telescopic device is...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to reduce the resistance caused by marine debris on the telescopic propulsion device during the ship's travel, reduce the impact of the propulsion propeller on the impact objects in the ocean, and reduce the impact on the telescopic side of the ship during normal navigation. Adverse effects such as eddy current resistance generated at the pushed cave
