Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed boats, and particularly relates to a hull structure of a high-speed rescue boat. Background Art

[0002] High-speed rescue boats are an important type of ship, which play a key role in multiple fields such as maritime search and rescue, military use, law enforcement patrol, and civil services. Among them, the hull line is a key factor affecting the speed performance. When the main dimension elements of the hull (such as the ship length, ship width, draft, etc.) and the main engine power are the same, different line designs will significantly affect the sailing speed, because the hull line is directly related to the resistance of the hull when moving in water, and the resistance is the key factor determining the sailing speed.

[0003] At present, the existing hull lines of high-speed boats generally adopt a single-fold angle line type. This structure generally has defects such as low sailing efficiency, high energy loss, serious wave slapping phenomenon, and low anti-wave slapping efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to propose a hull structure of a high-speed rescue boat in view of the above problems existing in the prior art.

[0009] In the above-mentioned hull structure of a high-speed rescue boat, the length of the hull is 6 meters and the width of the hull is 2.3 meters.

[0010] In the above-mentioned hull structure of a high-speed rescue boat, a reflective tape is pasted on the gunwale of the hull, and the reflective tape is used to collect external light sources and retro-reflect light.

[0011] In the above-mentioned hull structure of a high-speed rescue boat, the reflective tape is in a strip shape, and the reflective tape covers the gunwale of the hull.

[0012] In the above-mentioned hull structure of a high-speed rescue boat, a wave suppressor is rotatably connected to the stern of the hull, and a spring is provided between the wave suppressor and the hull.

[0013] In the above-mentioned hull structure of a high-speed rescue boat, a rubber strip is provided on the gunwale line of the hull.

[0014] In summary, the beneficial effects of the present utility model compared with the prior art are as follows:

[0015] A first fold angle and a second fold angle are provided on the bottom surface of the hull. The first fold angle extends from the stern of the hull to the bow of the hull, and the second fold angle extends from the bow of the hull to the stern of the hull.

[0022] The following are specific embodiments of the present utility model in combination with the drawings. The technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0023] Embodiment 1:

[0024] A hull structure of a high-speed rescue boat, as Figures 1 to 3 shown, including a hull 8. In this embodiment, the length of the hull 8 is 6 meters, the width of the hull 8 is 2.3 meters, and the hull 8 is made of fiberglass material. The fiberglass is made by pasting unsaturated polyester flame-retardant resin, alkali-free fiber cloth, and chopped strand mat.

[0025] The bow of the hull 8 is in a "V" shape. The "V" shape structure helps the water flow to separate more smoothly at the bow of the hull 8, thereby reducing the resistance suffered by the hull 8 and improving the navigation efficiency.

[0026] On the bottom surface of the hull 8, there are provided a first fold angle 1 and a second fold angle 2. The first fold angle 1 is located above the second fold angle 2. The first fold angle 1 extends from the stern of the hull 8 towards the bow of the hull 8, and the second fold angle 2 extends from the bow of the hull 8 towards the stern of the hull 8. The first fold angle 1 and the second fold angle 2 are both symmetrically distributed along the center line of the hull 8. By means of the first fold angle 1 and the second fold angle 2, the flow state of the water flow at the bottom of the hull 8 can be changed, so that the water flow can separate more smoothly when flowing through the hull 8, thereby reducing the resistance when the hull 8 moves. Moreover, the first fold angle 1 and the second fold angle 2 can guide the water flow to flow along the corresponding paths, so that the water flow forms a more concentrated and stable wake at the stern of the hull 8, thereby further reducing the resistance and improving the stability of the hull 8 and the navigation efficiency.

[0027] On the bottom surface of the hull 8, there are provided an upper anti-splash strip 3 and a lower anti-splash strip 4. The cross-sections of the upper anti-splash strip 3 and the lower anti-splash strip 4 are both triangular. The upper anti-splash strip 3 is located below the second fold angle 2, and the upper anti-splash strip 3 is located above the lower anti-splash strip 4. The upper anti-splash strip 3 and the lower anti-splash strip 4 both extend from the bow of the hull 8 towards the stern of the hull 8.

[0028] When the hull 8 is sailing in waves, the impact of the water flow and waves will generate water splashes and sprays around the hull 8. These sprays will not only increase the resistance of the hull 8, but may also cause discomfort to passengers and crew. By means of the upper anti-splash strip 3 and the lower anti-splash strip 4, the generation of sprays around the hull 8 by the water flow can be reduced, so that the water flow can flow more smoothly past the hull 8, and the upper anti-splash strip 3 and the lower anti-splash strip 4 can guide the water flow to flow along the corresponding paths, reducing the resistance caused by the water flow to the hull 8, thereby improving the navigation efficiency.

[0029] A reflective tape 5 is pasted on the gunwale of the hull 8. The reflective tape 5 is used to collect external light sources and retro-reflect light. By retro-reflecting light through the reflective tape 5, signals are transmitted to the searching aircraft, ships, and personnel.

[0030] The reflective strip 5 is strip-shaped, and the reflective strip 5 covers the gunwale of the hull 8, so as to increase the area of the reflective strip, enlarge the light reflection area, enhance the overall contour sense of the hull 8, make the hull 8 more prominent during navigation, thereby improving visibility, and further improving the navigation safety.

[0031] Embodiment 2:

[0032] The difference between Embodiment 2 and Embodiment 1 is that, as Figures 4 to 5 shown, a wave suppressor plate 6 is rotatably connected to the stern of the hull 8, and a spring 9 is arranged between the wave suppressor plate 6 and the hull 8. The wave suppressor plate 6 is used to suppress waves, reducing the generation of waves and splashes when the hull 8 moves at high speed, thereby improving the stability and navigation efficiency of the hull 8.

[0033] Furthermore, during the navigation of the hull 8, when the wave suppressor plate 6 is impacted by waves, the wave suppressor plate 6 rotates relative to the hull 8, and the buffering effect of the spring 9 can reduce the impact on the hull 8 and the wave suppressor plate 6.

[0034] A rubber strip 7 is arranged on the gunwale line of the hull 8. The rubber strip 7 can protect the edge of the hull 8. When docking and contacting other ships or objects, the rubber strip 7 can reduce the direct impact on the edge of the hull 8, prevent scratching and wear, extend the service life of the hull 8, and moreover, the rubber strip 7 has an anti-slip function. The rubber strip 7 can provide additional friction, reducing the risk of slipping when personnel get on and off the hull 8, thereby improving safety.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the present invention; those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
