Embodiment Construction
[0020] figure 1 A side view of an embedded composite fiberglass multipurpose boat is shown. figure 2 , 3 , 4, 5 have shown the connecting device that an airbag 2 is installed on the hull. The air bag 2 made of rubber or PVC material adopts a U-shaped structure, and is arranged on both sides of the boat and the freeboard outside the bow. Rods made of PVC3. The hull made of fiberglass adopts a lower hull 1 and an upper hull 1a, and a protrusion 1b is respectively provided on the inner sides of the upper hull 1a from the bow to the stern, and the embedded round hole 1c is provided In the protrusion 1b, the embedded circular hole 1c is specially provided with an embedded opening 1d communicating with the outboard. The connecting convex lines 2a on the airbag 2 correspond to the embedded openings 1d on both sides of the hull, so that the connecting convex lines 2a on the airbag 2 can be easily inserted into the embedded circular holes 1c on the hull. All the ring-shaped heads...

The invention discloses an airbag and hull connecting device of an embedded combined type glass-steel multifunctional boat, belonging to the technical field of work boats for flood control rescue and the like. The airbag and hull connecting device of the embedded combined type glass-steel multifunctional boat is characterized in that an airbag is mounted on a hull; and as the airbag is provided with a connecting raised line with an annular head, the hull is provided with built-in round holes with built-in openings, and the connecting raised line on the airbag corresponds to the built-in openings on the two sides of the hull, the connecting raised line on the airbag is easily inserted into or pulled out of the built-in round holes on the hull. The connecting device can be used for simplifying the process of mounting the airbag on the hull or removing the airbag from the hull, and effectively improving the safety and usability of the boat. The connecting device can be used for radically solving the problems in seaworthiness and potential safety hazard of the existing flood control rescue boat and the like as well as the problems in strength, ageing and marine erosion of the bonded part caused by the bonding in a physical chemistry manner for two large-scale split components made of different materials, and realizing quick production, maintenance and transportation management and low cost.
Description
technical field [0001] The invention relates to an air bag and hull connecting device embedded in a combined fiberglass multi-purpose boat, belonging to the technical field of flood control and rescue boats, offshore oil exploration boats, and fast landing operation boats in shoals. Background technique [0002] Most of the currently used flood control and rescue boats, offshore oil exploration boats, and fast landing operation boats in shoals are mainly fiberglass assault boats and rubber boats. These products are very mature in technology, but there are inherent defects in themselves. [0003] The main defect of the fiberglass assault boat is that its overall safety performance and usability cannot meet the rescue requirements in dangerous situations. The main manifestations are: due to the light weight of the hull and the high center of gravity when it is heavy loaded, it is very easy to capsize when it encounters rapids, storms, or water drops; when it collides with unc...
