Besides the unique hull construction technology, shipbuilding also relates to various fields of machinery, electricity, metallurgy, construction, chemistry, industrial art and the like. Therefore, shipbuilding is a comprehensive technology based on all industrial technologies, reflecting the industrial technology level of a country.
Due to different navigation areas, tasks and requirements of the ship, the ship product has the characteristics of multiple varieties and small production batch. Meanwhile, with the reduction of the current ship carrying capacity, the improvement of the automation degree, the special operation requirements of special ships and the like, more and more ships are provided with bow thrusters, and the most common of the ships is channel type (tunnel type) bow thrusters. The bow thrustor can change the ship heading under the condition of no rudder attack or poor low-speed rudder effect, and can realize the function of dynamic positioning on the sea, so the bow thrustor is widely applied to the working condition of positioning by leaning on a wharf or on the sea. Among various types of bow thrusters, the tunnel type thrusters have the advantages of large thrust, simple structure, no additional increase of draught, low cost and the like, so that a large amount of equipment is arranged on various ships.
Although the tunnel type bow thrusting has a plurality of advantages, the tunnel breaks the line type of the hull outer plate, a pair of tunnel ports are always arranged on the outer plate, the diameters of the tunnel ports are different according to the thrusting power, and the influence degree on the line type is different. Once the linear smoothness is damaged, the sailing resistance of the ship is increased, the sailing speed of the ship is reduced under the same power, or the oil consumption of the ship is increased under the same sailing speed, so that the rapidity and the economy of the ship are influenced, and the parameter indexes of the ship are unfavorable. In particular, for scientific vessels, the bottom of such vessels is fitted with a large number of acoustic devices for detection of the body of water or the sea bottom. The side-thrust tunnel portal can generate a large number of bubbles, and these additional bubbles can leak down to the ship bottom acoustic equipment area and interfere with the operation of the acoustic equipment.
In order to adapt to the defects caused by the increasing tunnel type side pushing, the ship industry needs a set of safe and efficient side pushing cover sealing devices to replace the past exposed side pushing tunnel entrance scheme or immature cover plate devices, and meanwhile, a modularized scheme can be provided in the design stage, so that the interfaces between a ship body and the side pushing cover sealing are reduced as much as possible, and a second watertight protection is provided.
