Abstract

The utility model discloses a high-speed boat which is characterized in that a side plate of a port bottom of a bow and a side plate of a starboard of the bow are both in a semi-hyperboloid shape, the center line of the bottom of the bow of the boat is a smooth connecting line formed by welding two semi-hyperboloids through arcs and is in a hyperboloid shape, the center line of the bottom of a midship is in a straight line shape, the center line of the bottom of the bow of the boat is in tangential connection with the center line of the bottom of the midship, and the side plates of the port bottom of the bow and the starboard of the bow are in smooth connection with other parts of a boat body through arcs. The shaping is beneficial to reducing wave slamming, reducing wave rising at the bow and reducing navigation resistance, thereby effectively improving the ship speed and prolonging the service life of the ship.

Description

High-speed boat

Technical Field

The utility model relates to the technical field of light and small boat design, in particular to a high-speed boat.

Background

The sailing resistance of the boat is mainly the resistance encountered by the bow and the hull, and the good hull design can improve the sailing resistance of the boat and increase the sailing speed, for example, patents with publication numbers of CN102050196, CN022445250, CN207403877 and the like mainly aim at improving the hull design. The bow still mainly takes a triangular shape or an arc shape as a main part at present, and partial ships are also assisted with a wave pressing design, and the like, so that the requirements of further improvement on reducing the navigation resistance of the bow and improving the ship speed are met.

Especially, law enforcement boats have the requirements of high speed, collision resistance, no less than rated passenger carrying capacity, convenience for embarking law enforcement and the like. Under the potential circumstances, the realization of increased speed performance by improving the bow profile is an urgent need for current law enforcement boats.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a high-speed boat, which can effectively reduce the navigation resistance of the bow and improve the navigation speed, and solve the above problems in the prior art.

In order to achieve the purpose, the technical scheme of the utility model provides a high-speed boat which comprises a bow port bottom side plate, a bow starboard bottom side plate, a bow bottom center line and a midship bottom center line, wherein the bow port bottom side plate and the bow starboard bottom side plate are in semi-hyperboloid shapes, the bow bottom center line is a smooth connecting line formed by welding the two semi-hyperboloids through arcs and is in a hyperbolic shape, the midship bottom center line is in a straight line shape, and the bow bottom center line is in tangential connection with the midship bottom center line.

Furthermore, the ship bow machine also comprises a ship body, wherein the ship bow port bottom side plate and the ship bow starboard bottom side plate are connected with the ship body in an arc smooth connection mode.

Furthermore, the hull is designed in a single body, folded angle and deep V-shaped hydroplane line type.

Further, the convex surfaces of the ship bow port bottom side plate and the ship bow starboard bottom side plate are upward.

Further, the center line of the bow bottom of the ship is convex downwards.

The utility model has the advantages and beneficial effects that: through the matched design of the ship body and the ship bow, the purposes of reducing wave slamming, reducing wave rising on the ship bow and reducing navigation resistance are achieved, so that the ship speed is effectively improved, and the service life of the ship is prolonged.

Drawings

FIG. 1 is a front view of a high speed boat according to the present invention;

FIG. 2 is a side view of FIG. 1;

the figures are labeled as follows:

the ship comprises a ship bow port bottom side plate 1, a ship bow starboard bottom side plate 2, a ship bow bottom center line 3, a midship bottom center line 4 and a ship body 5.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-2, the law enforcement aluminum alloy high-speed boat in the embodiment comprises a bow port bottom side plate 1, a bow starboard bottom side plate 2, a bow bottom center line 3, a midship bottom center line 4 and a boat body 5, wherein the bow port bottom side plate and the bow starboard bottom side plate are in semi-hyperboloid shapes, the bow bottom center line is a smooth connecting line formed by welding the two semi-hyperboloids through arcs and is in a hyperbolic shape, the midship bottom center line is in a straight line shape, and the bow bottom center line is in tangential connection with the midship bottom center line.

Preferably, the ship bow port bottom side plate and the ship bow starboard bottom side plate are connected with the ship body in an arc smooth connection mode.

Preferably, the hull is a mono-hull, dog-leg, deep "V" hydroplane design, which has good speed and heave resistance.

Preferably, the convex surfaces of the ship bow port bottom side plate and the ship bow starboard bottom side plate are upward.

Preferably, the center line of the bottom of the ship bow protrudes downwards, so that the front slamming force of the ship bow can be reduced.
