Description

Inland river imitation catamaran

Technical Field

The application relates to the technical field of ships, in particular to a inland river simulated catamaran.

Background

In our country, many sceneries are known from mountain and water sceneries. Meanwhile, many small and medium cities are built along the small and medium rivers. Green water and blue mountain are valuable resources. Natural waterscapes have recently been developed and maintained secondarily. There is a ship with water, and a completely different experience is provided for pleasure boats to visit on a landscape site with water, than for walking on shore. One of the characteristics of the water scenery tourist attractions connected with the small and medium rivers and mountains beside the small and medium cities is that the water is shallow, especially in non-high water seasons such as autumn and winter. The design of the sightseeing boat brings great difficulty.

Take the well-known mountain and water scenic spot Lijiang as an example. Because the water in the dribbling river is shallow, most of bamboo rafts are used as tools for carrying tourists, but the safety of the bamboo rafts is difficult to ensure. Or by using a traditional wood ship which is short and wide. However, the structural strength, water resistance and corrosion resistance of the wooden ship are difficult to ensure, and meanwhile, due to the shallow water, the large-size ship is difficult to prepare. Or the short and wide pleasure boat welded by the thin steel plates for the traditional wooden ships is used as a reference, and the pleasure boat lacks modern breath, has a narrow moving range and is difficult to meet the demands of users. Therefore, a pleasure boat which has modern breath, is safe and energy-saving, has a wide range of motion and is suitable for operation of waterscape spots in shallow water needs to be prepared.

In this embodiment, the boundary between the left hull 100, the middle hull 200, and the right half hull 10 is a plane parallel to the X-axis. This means that the water flow is in a straight line parallel to the X-axis at the boundary line, without adverse interference between the three hulls 10. Thus, three excellent ship forms with small resistance are stacked, and the excellent energy-saving ship form with small resistance is obtained.

In one specific embodiment, the left hull 100 and the right hull 300 are symmetrically arranged, and the ratio of the ship width of the left hull 100 to the ship length of the left hull 100 is: 1:16-1:11.

In one specific embodiment, the middle part of the side projection of the middle hull 200 is horizontal and two ends of the middle hull are slightly tilted. In this embodiment, the middle hull 200 is slowly lifted like a rectangular plate at both ends. Just like a water ski with two tilted ends. This results in a longitudinal flow and a slow inflow and outflow. The characteristics of the traditional excellent energy-saving ship type longitudinal flow wave pressing ship type are met, so that the resistance of part of the ship is small, and the energy-saving performance is good.

In one specific embodiment, the hull 10 is made of steel, and the waterline of the hull 10 is less than 0.7m; or the hull 10 is made of aluminum alloy, and the waterline of the hull 10 is smaller than 0.5m. In this embodiment, it is noted that the new ship type optimizes the underwater portion. The required draft is reduced by substantially half, from 0.85 meters to about 0.50 meters in the case of steel vessels. If the bamboo raft is made of aluminum alloy, the weight of the aluminum alloy is less than half of that of steel, the draft can be reduced to about 0.3, and the bamboo raft can basically follow the back of the river-dribbling bamboo raft.
