Problems solved by technology

However, in this patent, the tractor pulls the ship forward to realize navigation, and the ship is easy to swing left and right along the water flow in the river. At the same time, the patent navigation control method is simple, which makes the navigation stability poor and the safety low

specific Embodiment approach

[0061] A method for controlling ship navigation in a two-end traction type tunnel, wherein tractor tracks are arranged along the length direction of the tunnel on both sides of the tunnel or on the top of the tunnel, and tractors are arranged in pairs along the front and rear directions on the tractor tracks. A traction device is provided, and the traction device includes a traction rope for towing the ship. The navigation control process specifically includes the following steps:

[0062] (1) After the bow of the ship enters the tunnel, the ship stops self-propelled, and two traction ropes are released from the tractor in front to connect with both sides of the bow, so that it forms a forward traction on both sides of the bow;

[0063] (2) Control the front tractor to move forward and release the traction rope, so that the angle between the traction force of the bow of the traction rope and the horizontal direction reaches the set value α1, and the angle between the bow tracti...

Abstract

The invention discloses a navigation control method for ships in a two-end traction type tunnel, which is characterized in that tractor tracks are arranged along the length direction of the tunnel on both sides of the tunnel or on the top of the tunnel, and the tractor tracks are arranged in pairs along the front and rear directions. Tractor, the tractor is equipped with a traction device, the traction device includes a traction rope used to tow the ship, in the navigation control process, the forward traction is applied to the ship by the tractor in front, and the traction force is exerted on the ship by the tractor in the rear. A backward reverse restraint force is applied, and the ship is controlled to pass through an acceleration segment and then drive out of the tunnel at a constant speed at a constant speed. The invention has the advantages of better ship towing navigation effect, better navigation stability and higher safety.

Description

technical field [0001] The invention relates to the technical field of tunnel ship navigation, in particular to a method for controlling navigation of tunnel ships with traction at both ends. Background technique [0002] In water transportation projects, in order to realize the navigation of ships in restricted areas, closed waterways are often excavated through mountains, called navigation tunnels. my country's mountainous area accounts for nearly 70% of the country's total land area. In order to further improve the level of mountainous river channels, it is often necessary to design and dig artificial canals. When the artificial canal encounters high mountains and ridges and it is difficult to bypass, it is necessary to excavate tunnels through the high mountains and ridges for navigation. The axis of the hydraulic tunnel is generally a straight line, and the water depth, width and navigation clearance of the tunnel should meet the navigation requirements, and are usuall...
