Figure BDA0002569342320000041
The waterplane coefficient of the inflatable boat is large, so that the pitching, heaving, head shaking and vertical acceleration of the inflatable boat during navigation can be obviously reduced, the head wave slamming probability is also obviously reduced, the wave resistance and the course stability are improved, and the stall of the inflatable boat during navigation in stormy waves can be reduced.
The bottom slant angles β of the front section BC in the hull, the middle and rear sections CD of the hull and the rear section DE of the hull are 20-25 °, the bottom slant angles of the front section BC in the hull, the middle and rear sections CD of the hull and the rear section DE of the hull in this embodiment are all 23 ° in the same manner, the bottom slant angle of the front section AB of the hull gradually increases from tail to head to 58-62 °, the bottom slant angle of the joint of the front section BC in the hull and the front section AB of the hull is the same, and the bottom slant angle β of the front section AB of the hull in this embodiment gradually increases from tail to head to 60 ° in the same manner of 23 °. The larger bottom tilt angle in this embodiment provides the inflatable boat with good course stability, particularly with better inward roll characteristics during cornering, while also reducing the jolts and wave slamming experienced by the inflatable boat when traveling in waves.
The tail of the boat body 1 is provided with a support 6, and the support 6 is provided with a self-righting air bag 5. When the inflatable boat is in normal navigation, the self-righting air bag 5 is in a non-inflatable state, so that the air resistance in navigation can be reduced, and when the rigid inflatable boat overturns accidentally, the self-righting air bag 5 can be automatically inflated to help the rigid inflatable boat to be self-righted. The deck 4 of the rigid boat is provided with a driving console 7 and a boat lifting device 8, the driving console 7 is arranged at the middle rear part of the deck in the embodiment, the front part of the driving console 7 is provided with the boat lifting device 8, and the boat lifting device 8 is used for lifting the manufactured inflatable boat into water.
In the embodiment of the invention, the material structure of the submarine body is a sandwich structure of the ultra-high molecular weight PE fiber reinforced composite material and the foam core material. The weight of the boat body structure can be greatly reduced by using the material, and the weight can be reduced by 50% compared with the traditional glass fiber reinforced plastic boat. Meanwhile, when the boat body is impacted, the sandwich structure foam core material can effectively absorb energy generated by the impact, greatly reduce the influence of the impact on the boat body and protect the boat body from being damaged. In addition to service environment, if need sail in many reefs region or have the requirement of dashing the beach, can also be equipped with one kind and set up the outer special high wear-resisting PE fibrous layer at hull for hull is when scraping with the reef or dashing the beach, only can produce a small amount of mar at high wear-resisting PE fibrous layer, and hull itself does not receive the damage, and this high wear-resisting PE fibrous layer quality loss is also lower after rubbing many times simultaneously, adapts to the requirement of sailing in many reefs region and dashing the beach well.
In addition, the inflatable fender material is a composite base fabric of high-performance PE fiber reinforced TPU (thermoplastic polyurethane). The inflatable fender adopts a high-frequency heat welding technology to form a multi-independent cabin structure. Compared with the traditional fender material, the puncture resistance of the inflatable fender is improved by two times, the wear resistance of the inflatable fender is improved by four times, and the service life of the inflatable fender is 7-8 years and is far longer than that of the traditional fender material (5 years). Meanwhile, the tensile strength and the peel strength of a welding seam formed by a thermal welding technology are far stronger than those of a traditional mode of bonding through an adhesive, and the structure of the multiple independent cabins also ensures that other cabins can still be kept normal when a single cabin or a small number of cabins are damaged, so that enough buoyancy and safety support are provided for the ship body.
