Drawings

The present invention will be further described with reference to the accompanying drawings and specific embodiments, wherein:

fig. 1 is a front view of an embodiment of the present invention;

fig. 2 is a side view of an embodiment of the invention.

Detailed Description

Referring to fig. 1, the utility model discloses a shallow V type ships and light boats, including hull 1 and hull 2 of upper and lower integrative, hull 2 is the V type, and the angle of declination alpha of 2 prelude at the hull bottom is 28-43, the angle of declination alpha of 2 afterbody at the hull bottom is 3-8, the hull bottom 2 is equipped with pressurized-water fin 3.

Specifically, the slant angle of the bow part of the ship bottom 2 is 28 degrees to 43 degrees, the bow part meets the requirement of wave breaking during high-speed navigation, the slant angle of the tail part of the ship bottom 2 is 3 degrees to 8 degrees, and the smaller slant angle of the tail part has the function of lifting the ship body, so that the requirement of shallow draft is met, and the stability of the ship at different speeds is considered; the ship bottom 2 is provided with the water pressing fins 3, the water pressing fins 3 extend into water, the underwater width of the ship is increased, the water pressing fins 3 can prevent the ship from transversely shifting, and the motion response of the ship at high speed and in waves is reduced, so that the stability of the ship at high speed is better; the situation that the boat is unstable due to the fact that the underwater contact area of the boat is small and the boat is subjected to the action of transverse moving force along with tide and wind waves is avoided.

Further, the two sides of the ship bottom 2 are provided with the water pressing fins 3. The water pressing fins 3 on the two sides prevent the boat from transversely shifting, so that the motion response of the boat at high speed and in waves can be obviously reduced, and the rolling is reduced. Moreover, the water pressing fins 3 on the two sides can press water splashed on the two sides to a certain extent, favorable wave making interference is generated, larger waves are avoided, a certain wave eliminating effect is achieved, and the navigation requirement of a shallow water area is further met.

Furthermore, the length of the hydrofoil fins 3 is three-quarters of the length of the ship bottom 2. The height of the water pressing fins 3 is gradually increased and then gradually reduced from the tail to the head, and the height of the water pressing fins 3 at the tail is larger than that of the water pressing fins 3 at the head.

Specifically, the water pressing fin 3 comprises a first water pressing fin 4 arranged on the outer side of the ship bottom 2 and a second water pressing fin 5 close to the central axis of the ship bottom 2.

The first water pressing fin 4 is arranged at the joint position of the ship bottom 2 and the ship body 1, the upper end of the first water pressing fin 4 is connected with the ship bottom 2, the outer side surface of the first water pressing fin 4 is an arc surface 41, the inner side surface of the first water pressing fin 4 is a first plane 42, and the arc surface 41 is intersected with the bottom edge of the first plane 42. The first hydrofoil 4 acts to stop the boat from traversing and breaking waves.

Similarly, the second water pressing fin 5 is arranged between the first water pressing fin 4 and the central axis of the ship bottom 2, the second water pressing fin 5 is in an inverted triangle shape, the upper end of the second water pressing fin 5 is connected with the ship bottom 2, the outer side surface of the second water pressing fin 5 is a second plane 51, the inner side surface of the second water pressing fin 5 is a third plane 52, and the bottom edges of the second plane 51 and the third plane 52 are intersected. The primary function of the second hydrofoil 5 is to prevent the boat from traversing.

Referring again to fig. 2, each longitudinal section of the boat from bow to stern has a different angle of ascent α, the angle of ascent of the bottom 2 decreasing from bow to stern. Furthermore, the angle of inclination of the fore part of the ship bottom 2 is 29.5-34.5 degrees, preferably 30 degrees, and the angle of inclination of the aft part of the ship bottom 2 is 3.5-7.4 degrees, preferably 3.5 degrees. The angle of inclination of this ship is greater than general high-speed ship, and the hull bottom 2 of this ship is shallow V type promptly, and shallow V type and the compound mode of pressing water fin 3 can effectual increase ship's stability when high-speed navigation.

The bottom of hull bottom 2 is equipped with the fossil fragments, the fossil fragments are flat keel, and the horizontal width of flat keel is about 100mm, and the fossil fragments of ships prelude are lower, and the fossil fragments of ships afterbody are higher. When the boat is planing at high speed, the flat keel at the boat tail acts to reduce drag, which is also the reason why the keel at the boat tail is higher.

In addition, the side of hull 1 is equipped with first dog-ear 6, second dog-ear 7 and third dog-ear 8 from up in proper order down. The first folding angle 6 is close to the first water pressing fin 4, the step part above the first water pressing fin 4 is larger, the contact area with the water surface is favorably increased, the stability of the ship body is better, the phenomenon of large-angle inclination caused by different loads on two sides of the ship is reduced, the transverse inclination angle of the ship is smaller, and the transverse stability is better; the second and

third folding angles

7 and 8 are provided at the upper end of the hull 1 to block water splashes. The water bloom can be along 2 upper end motions to hull 1 at the bottom of a ship during navigation, and first dog-ear 6, second dog-ear 7 and third dog-ear 8 for the upward movement of original water bloom becomes level and downstream, has prevented that the water bloom from splashing on the deck of ship, and consequently the water bloom that this ship produced when navigation is less, and the pressurized-water fin has played the effect of wave absorption, has further reduced the water bloom.

The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should be all included in the protection scope of the present invention as long as the technical effects are achieved by any of the same or similar means.
