Embodiment Construction

[0012] 1. A railing should be properly set up at the water swallowing port of the bow to prevent larger debris or organisms in the water from being swallowed, resulting in pipeline blockage.

[0013] 2. The ratio of the hollow diameter of the water accelerator drum to the inner diameter of the drum should not be too small, and the casualties of creatures swallowed into the water should be minimized.

[0014] 3. There are several blade-type spiral grooves in the drum of the water accelerator, which can be designed to rotate the drum by mechanical transmission, or it can be designed as the rotor of the motor. Of course, if there are other more advanced and reasonable methods, feel free to adopt them.

[0015] 4. The center line of the water flow pipe should be roughly parallel to the bottom of the ship, or the rear side should be inclined downward appropriately.

[0016] 5. The "water-swallowing ship type" is designed to use the water spray at the outlet of the water flow pipe ...

Abstract

The invention relates to a technique for a 'water-swallow ship form' design, which belongs to the field of shipbuilding, and is suitable for manufacturing ships of which the prows have certain draughts during advancing, but is not suitable for manufacturing the ships of which the prows have shallow draughts during advancing, such as speed boats, small-sized yachts, wooden boats and the like. The 'water-swallow ship form' design is an effective method for reducing the water resistance for a boat during advancing. The basic principle of the 'water-swallow ship form' design is that the inner part below a draught part of a ship is designed and manufactured with a water flow pipeline with a larger front part and a smaller rear part, and a water flow accelerator is arranged in the pipeline. Thus, when the ship moves forwards, a part of water in front of the prow is smoothly swallowed into the water flow pipeline, and the water is accelerated by the water flow accelerator and flows backwards. The water flow is accelerated for one time even more times and is finally spurted out at a high speed from an outlet of the water flow pipeline below the stern. Therefore, the swallowed water not only reduces the resistance to the ship during advancing, but also plays a role in driving the ship forwards and becomes the main power for driving the ship to move forwards. Although the water flow pipeline occupies certain space in the lower part inside the ship, the ship obtains the power for moving forwards and accelerates the advancing speed of the ship while reducing the water resistance. Obviously, the advantages far outweigh the disadvantages.

Description

1. Technical field [0001] The "water-swallowing ship type" design technology belongs to the field of shipbuilding and is suitable for ships with a certain draft at the bow when advancing; it is not suitable for ships with a shallow draft at the bow when advancing, such as speedboats, small pleasure boats, and wooden boats. 2. Background technology [0002] The vast majority of ships move forward by parting the water ahead with their bows. So, is there any other better way to reduce the water resistance when the boat moves forward? The design of "water-swallowing ship" is exactly an effective way to reduce the resistance of water when the ship advances. 3. Contents of the invention [0003] 1. Core design content [0004] As shown in the accompanying drawings. A water flow pipeline is designed in the interior below the draft part of the ship, the inner diameter of the bow part pipeline is larger, the inner diameter of the stern part pipeline is smaller, and a water flow ...
