Three-body wave-absorbing planing boat

Technical Field

The utility model relates to a boats and ships technical field, concretely relates to three-body wave absorption planing boat.

Background

A water planing boat for inland river, lake or coastal water area features that it is a dynamically supported boat, which is driven by the hydrodynamic lift generated by high-speed navigation to lift the boat body to plane on water surface. The water skimming boat is mainly composed of a boat body and a deck (superstructure), wherein the boat body can be divided into a bow and a stern with large difference of head and tail line types. In the prior art, the hull of a hydroplane is mostly in a single break angle line type or a double break angle line type, and the midpoint of the break angle line is called as a midship. Under certain sailing conditions, the mono-hull or twin-hull planing boats have their own advantages, but they also have some common disadvantages.

Firstly, the vessel body has poor wave elimination and large bow wave making, which not only increases the power consumption of the planing boat, but also has serious scouring to the riverbed and has serious interference to other ships and personnel in the channel. Secondly, the stern is narrow, so that the turning radius is large and the maneuverability is poor. Thirdly, due to poor air lubrication of the stern planing surface. So that the sliding resistance is large and the navigation speed is limited to a certain extent. In addition, in the case of a fixed power of the main machine, the effective usable area of the deck is small, and the comfort of the passenger seat is limited. The combined effect of the above factors makes the mono-hull or twin-hull planing boat of the prior art less economical to operate.

As a preferred technical solution of the present invention: the inside splashproof strip that is provided with of supplementary hull, the cross section of splashproof strip is triangle-shaped.

As a preferred technical solution of the present invention: the opening of the channel is gradually increased along the direction from the bow to the stern, and the depth of the channel is gradually reduced.

The utility model discloses following beneficial effect has:

1. by arranging the wave-absorbing fins, wave-making resistance is reduced, dynamic lift force is increased, wet surface area is reduced, bow side waves are eliminated by 90%, stern waves are eliminated by 70%, resistance reduction is about 15%, and the wave-absorbing structure is more suitable for high-speed sailing in shallow water and narrow channels.

2. The arrangement of the channel can slow down high-speed slamming, improve the wave resistance and improve the riding comfort.

3. Compared with a single yacht with the same size, the berthing plate area is 16- ~ 20% larger, the effective use area and the cabin capacity are increased, and in addition, the room is reserved for modification and equipment increase.

Detailed Description

In order to make the objects and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIGS. 1-4, the embodiment of the utility model provides a three-body wave-absorbing planing boat, including well hull 1, well hull 1 bilateral symmetry is provided with supplementary hull 2, and well hull 1, two supplementary hulls 2 pass through deck 3 and connect, and the top of deck 3 is provided with superstructure 7 and sets up power and direction control device on superstructure 7 deck 3, and well hull 1, two supplementary hulls 2 pass through deck 3 and connect, make the utility model discloses an effective area of deck 3 compares with the monomer speed boat that the yardstick is equivalent, and the area has increased 16% ~ 20%, has not only increased effective usable floor area and hold, and leaves the leeway for repacking and equipment increase.

The cross section of the middle ship body 1 is gradually transited to the square shape of a stern from the V shape of a ship bow, a channel 4 is formed between the middle ship body 1 and the auxiliary ship body 2, the opening of the channel 4 is gradually increased along the direction from the ship bow to the ship stern, and the depth of the channel 4 is gradually reduced, so that the tail buoyancy is large, the low-speed stern absorbs little water, the draught is shallow, the high-speed sailing angle is small, the draught of the single express boat with the maximum sailing specific dimension is 8 ~ 10cm smaller, when in sliding, high-speed airflow enters the channel 4 from the opening to form an air cushion, the generated additional lift force and the hydrodynamic lift force lift the boat body together, and the lifted boat body only generates small displacement and the shallow draught, thereby effectively reducing the wet surface area of the boat body, enhancing the air lubrication of the sliding surface, reducing the sliding resistance, slowing down high-speed slamming, improving the wave resistance and improving the riding comfort;
