Problems solved by technology

The advantage of this production and installation method is that it is convenient for the installation of nozzles and jet pump equipment in the water jet propulsion system, as well as the adjustment of the transmission device, and the installation accuracy of the equipment can be ensured by adjusting the structure of the water inlet channel; however, the shipyard is a scarce resource for shipyards. The construction period is also an important criterion to measure the manufacturing level of the shipyard. The method of bulk packing a large number of parts on the berth greatly prolongs the construction period of the berth and increases the workload of the berth. This method is in line with the current requirements to ensure the integrity of the sections and reduce the construction period of the berth. run counter to the requirements of

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] Please refer to the attached Figure 1-9 , a ship water inlet channel provided by the present invention, which includes a water inlet channel first zone part 1, a water inlet channel second zone part 2, and a curved cylindrical elbow part connected in sequence along the water flow direction 3 and the spout part 4; it also includes a stern shaft protection tube 5 parallel to the horizontal plane passing through the second area part 2 of the water inlet channel and connecting the stern shaft protection tube 5 and the elbow part 3 Anti-resonance sheet 6 on the top of the inner surface.

[0029] Based on the above technical features, by dividing the ship’s water inlet...

Abstract

The invention discloses a ship water inlet passage and manufacturing and an installation method. The ship inlet passage comprises a water inlet passage first area assembly, a water inlet passage second area assembly, a bent assembly in a curved cylindrical shape, a nozzle assembly which are connected in the stream direction in sequence; and further comprises a tail shaft protection pipe parallel to the water level and with one end penetrating through the water inlet passage second area assembly and an anti-singing edge used for connecting the tail shaft protection pipe and the top of the innersurface of the bent assembly. The advantage of bulk loading of the water inlet passenger structure on a berth is preserved, and meanwhile, the condition of a large number of parts being in bulk on the berth is avoided.

Description

technical field [0001] The invention relates to a ship water inlet channel and a manufacturing and installing method thereof. Background technique [0002] In the field of ships, water jet propulsion is a special propulsion method, which uses the reaction force of high-speed water jetted from the jet pump to propel the ship forward. Compared with traditional propeller propulsion, water jet propulsion has more advantages, such as shallow draft, high propulsion efficiency, low underwater noise, strong adaptability to working conditions, and good performance of high-speed space-time bubbles. Generally speaking, the water jet propulsion system is mainly composed of water inlet channel, nozzle, jet pump and transmission device, steering and reversing device and other parts. The water inlet channel is not only an important part of the water jet propulsion system, but also an organic whole with the main hull structure. Therefore, the production method and installation stage of the...
