Description

[0001] Current vessels have limited speed improvements, and there are no precedents for vessels capable of both water transport and ice transport. This design and equipment, using AB C1 C2 propulsion, aims to increase the speed of vessels and enable combined water-ice-road transport. The design and equipment scheme are as follows:

[0002] The current A-type fast sailing vessel has propulsion systems 1 and 2 at the stern. This design adds propulsion systems 3, 4, and 5 on both sides of the bow. The diameter and power of the bow propulsion system are increased, and propulsion systems 4 and 5 on both sides are rotated inward by 5-10 degrees. Propellers 3, 4, and 5 are positioned at the waterline and the middle of the hull. This design is revised based on experimental data.

[0003] With the thrust of the stern propeller and the pull of the bow propeller, Scheme A's speed is 0.5-1.5 times faster than the current speed.

[0004] Option A can be tested on various sizes of ships and is applicable to submarines.

[0005] Type B ice-water amphibious vessel features ice sleds extending two-thirds of the vessel's length from the bow to the stern, with a width of 1.435 meters. It also has a rope anchor point at the bow and a high-powered electric fan above the waterline at the stern to propel the vessel at high speed across the ice. It is suitable for icebreakers.

[0006] This plan involves constructing an ice-water harbor on the ice surface, with high-power electric towing wheels anchored at anchor points on the ice surface. A 1.435-meter-wide high-speed rail track connects the ice surface to the underwater sloping slide, with limiting strips installed on the inner side of the track. The distance between the two slides is 10-40 meters, allowing ships ranging from 10,000 to hundreds of thousands of tons to be towed ashore by ropes to C1 and C2 amphibious vessels. Three sliding plates (front, middle, and rear) are installed on both sides of the bottom of the existing ship, with a width of 1.435 meters and a length exceeding half the total length of the ship. The bottom of the ship and the sliding plates are assembled using connecting frames, and a rope anchor point is located at the bottom of the bow.

[0007] A high-speed rail line is set up between land and water, and a ramp from the land to the underwater section is set up on the shore. A high-powered electric wheel is used to lift C1 and C2 onto the shore.

[0008] The C1 skateboard and the 50-meter-long high-speed rail trailer are locked in the front, middle and rear, and can slide up, down and left and right. It features a shock-absorbing and noise-reducing design and is equipped with a high-power electric fan above the waterline at the stern, enabling multimodal transport by water, land and ice.

[0009] The C2 features multiple sets of 1.435-meter-gauge electric high-speed wheels on both sides of the skateboard, with a waterproof design. The skateboard and axle frame can slide up, down, left, and right, and are equipped with shock absorption and noise reduction designs. The electric high-speed wheels of the skateboard are equipped with protective cylinders, which are opened when going up or down slopes and closed when submerged in water.

[0010] Platforms are set up on tracks C1 and C2, and assembly lines are set up in the shipyard. The above design and equipment are based on the upgrading, transformation and cross-system combination of existing technologies and equipment. The electric high-speed rail wheels are waterproof, the 50-meter-long high-speed rail trailers operate safely, and the track gradient, curve design and ship design equipment are matched with each other. The design is feasible and the equipment is feasible.

[0011] The above-described and related designs and applications are within the scope of protection of this invention.
