Embodiment Construction

[0009] A law enforcement high-speed boat, characterized in that the sliding surface of the bottom of the hull 1 is sequentially provided with a step-down step 1 4 , a step-down step 2 , and a step-up step 3 6 of decreasing length along the bow 2 to the stern 3 , wherein the step-down step The front ends are all arc-shaped and forward-inclined. When the present invention is in use, because the bottom of the hull 1 adopts the structure of step steps, the wet surface area can be effectively reduced. The large amount of air intake forms an air curtain at the bottom of the hull to reduce the resistance during sailing and effectively increase the sailing speed. In addition, the stepped steps adopt a scheme of decreasing length in order to keep the boat in good power during sailing position, and further improve the sailing state of the boat. The present invention has significant advantages such as low cost, reasonable structure, safety and reliability.

Abstract

The invention relates to the field of ship engineering, in particular to a law enforcement high-speed boat. The law enforcement high-speed boat is characterized in that: a broken step I, a broken step II and a broken step III, the lengths of which are gradually reduced, are sequentially arranged on the bottom sliding surface of a hull along the stem to the stern, wherein the front ends of the broken steps are arc-shaped and inclined backwards. During use, because the structure of the broken steps is adopted at the bottom of the hull, the wetted surface area can be effectively reduced; meanwhile, because arc-shaped and forwards inclined structures are adopted at the front ends of the broken steps, the air inlet quantity can be increased, and an air curtain is formed at the bottom of the hull to achieve the effect of reducing the sailing resistance and effectively improve the sailing speed; in addition, the scheme that the lengths are gradually reduced is adopted in the broken steps, so that the boat keeps a good power position during sailing and the sailing state of the boat is further improved; and the law enforcement high-speed boat has the remarkable advantages of low cost, reasonable structure, safety, reliability and the like.

Description

Technical field: [0001] The invention relates to the field of ship engineering, in particular to a law enforcement high-speed boat. Background technique: [0002] As we all know, ships are important means of water transportation. The fast pace of modern society has gradually increased people's requirements for the speed and reliability of ships. According to research, when a ship reaches a certain speed, it will generate lift to lift the ship. , to make it slide on the water surface, and because the wet surface area of ​​the bottom of the existing boat is relatively large, it will generate a lot of frictional resistance. Invention content: [0003] In order to overcome the shortcomings of the prior art, the present invention proposes a law enforcement high-speed boat with reasonable structure, low cost, safety and reliability. [0004] The technical measure that the present invention adopts is: [0005] A law enforcement high-speed boat, characterized in that the sliding...
