Embodiment Construction
[0033] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0034] When the ship's propeller is in operation, it pushes the water towards the stern, and the water produces a reaction force on the ship 100, thereby pushing the ship 100 forward. However, during this process, since the propeller 120 pushes the water flow backwards, there is a relatively large divergence angle, so that the direction of the reaction force of the water flow on the ship 100 is not all consistent with the direction of travel of the ship 100. energy loss. Therefore, in order to improve the utilization efficiency of energy and save energy, the inventors of the present application started from the perspective of reducing the divergence angle of the water flow pushed by the propeller 120, and provided a method for setting the ship 100 and the propeller 120, so as to improve the utilizat...

The application provides a ship and a propeller setting method. The ship comprises a ship body. When the ship body enters water, the bottom of the ship body is immersed in water; a channel is formed in the bottom of the ship body and used for arranging a propeller, and an outlet of the channel is located in the tail of the bottom of the ship body; and the inner diameter of the channel between thepropeller and the outlet is not larger than the positioning inner diameter, the diameter of the propeller is smaller than the positioning inner diameter, the difference ratio of the diameter of the propeller to the positioning inner diameter does not exceed a preset difference ratio, the positioning inner diameter represents the inner diameter of the channel where the propeller is arranged, and the preset difference ratio is between 0 and 0.3. When the propeller is arranged in the channel, the water flow in the channel is pushed to the outlet direction when the propeller rotates. Therefore, the divergence angle when the propeller pushes the water flow backwards during operation can be effectively reduced, the thrust generated by the water flow is close to the forward and backward directions, so that the utilization efficiency of energy is improved, and the effect of saving energy is achieved. Meanwhile, water flows through the channel at the bottom of the ship body to improve the stability of the ship body.
Description
technical field [0001] The present application relates to the technical field of ship propulsion, in particular, to a method for setting a ship and a propeller. Background technique [0002] The propeller is arranged at the stern of the hull, and when the propeller rotates, it drives the water to flow backward to propel the ship to run. However, in this way, the energy utilization efficiency is not particularly ideal, because the operation of the ship needs to consume a large amount of energy, therefore, in order to save energy, it is necessary to further improve the energy utilization efficiency. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a method for setting up a ship and a propeller, so as to improve energy utilization efficiency and save energy. [0004] In order to achieve the above object, the embodiments of the present application are realized in the following ways: [0005] In the first aspect, an em...
