Embodiment 1

[0054] Such as figure 1 and figure 2 As shown, when the ship is running with no load, the ship needs a certain amount of ballast water or needs to reach a certain draft to maintain the stability of the ship. At this time, the water inlet 1 at the bow is opened, the bottom water inlet 8 is closed, and the seawater It flows into the pipeline from the water inlet hole 1 at the bow and is discharged from the water outlet hole to realize live water ballast and avoid environmental pollution caused by stagnant water ballast. The shaftless propeller 6 is placed in the pipeline to form an integrated design of boat and oar, without external propellers, which improves the propulsion efficiency. When the ship needs power, the shaftless propeller 6 in the pipeline rotates to push the ship forward. At the same time, the subdivision in front of the pipeline can be adjusted to adjust the height of the water level in the pipeline, and then the stability of the ship can be adjusted, and the ...

Embodiment 2

[0056] When the ship is fully loaded, the ship does not need ballast water to meet the draft requirements, such as figure 1 shown. At this time, the bow water inlet 1 is closed, the bottom water inlet 8 is opened, and sea water flows into the through-type pipeline 2 from the bottom water inlet 8, and flows out from the water outlet. The propulsion water required by the shaftless propeller 6 is provided through the water inlet hole 8 at the bottom. When the ship needs to change the speed of the ship, the number of the bottom water inlet holes 8 can be adjusted to meet the requirement of the propulsion water volume, and the speed of the ship can be adjusted by adjusting the rotating speed of the shaftless propeller 6 simultaneously. It is also possible to adjust the speed of the ship comprehensively by adjusting the speed of the propeller to match the number of holes in the bottom water inlet.

Embodiment 3

[0058] When the ship is sailing with load, the ship needs a certain amount of ballast water or the ship needs to reach a certain draft. At this time, the part of the bow inlet hole 1 is opened by the pressure and flow detection control device 9, so that a certain amount of seawater enters the pipeline. At the same time, the subdivision 15 of the pipeline in front is used to adjust the water level of the seawater in the pipeline, so as to meet the requirement of regulating the stability of the ship. At the same time, part of the bottom water inlet hole 8 is opened to supplement the required propulsion water volume of the shaftless propeller 6 in the pipeline. When the ship needs to change the speed of the ship, the number of the bottom water inlet holes 8 is matched with the speed of the shaftless propeller 6 to meet the propulsion demand of the ship.

Abstract

The invention discloses a flowing water ballast and paddle integrated environmentally friendly ship and belongs to the field of ship ballast water and energy conservation. According to the flowing water ballast and paddle integrated environmentally friendly ship of the invention, a plurality of through pipelines are used for replacing the ballast tanks of the ship; and the front pipelines are subjected to cabin division processing along the direction from the bow to stern of the ship, so that a plurality of cabins can be defined; a gathering cabin is arranged on the rear pipelines; a shaftlesspropeller is arranged in the pipelines behind the gathering cabin; and therefore, paddle integration is realized. Water inlet holes are formed in the bow and bottom of the ship body are formed in thethrough pipelines; and devices for detecting the flow velocity and flow of an inlet and an outlet are arranged at the inlet and the outlet. The height of the water level in the pipelines can be adjusted by controlling the positions and number of the cabins, so that the stability of the ship is adjusted; the flow velocity and flow of seawater in the pipelines are adjusted by controlling the opening sizes of the bow water inlet holes and the bottom water inlet holes; the navigational speed of the ship is adjusted by controlling the rotating speed of the shaftless propeller and the flow speed ofseawater in the pipelines. The ship has the advantages of small pollution, high propulsion efficiency, low cost and the like, and particularly meets the requirement of ship pollution prevention.

Description

technical field [0001] The invention belongs to the technical field of ship ballast water treatment and energy saving, and more specifically relates to a through-type pipeline instead of a ballast water tank, and a shaftless propeller placed in the pipeline, which has the advantages of low cost and little pollution. A green boat featuring integrated live water ballast and oars. Background technique [0002] Ship's ballast water refers to the water and suspended matter added to the ship to control the ship's heel, trim, draft, stability or stress. It is reported that the ballast water carried by ships around the world exceeds 12 billion tons every year, which contains a large number of foreign organisms such as bacteria and microorganisms, which has caused serious biological pollution to the local ecological environment, and the problem of ballast water has also received more and more attention. Pay attention to. However, the traditional ballast water treatment method has t...
