The existing ship lock through capacity cannot meet the future demand for lockage. However, in the process of promoting the planning and construction of water transport new channel of Three Gorges hub, it is found that the water transport new channel planning channel route needs to pass through a large mountain, and when the ship passes through the water transport new channel, it needs to sail through the long tunnel channel, and the water level fluctuation of the upper reaches of Three Gorges hub is large.

[0057] The embodiment provides a ship traction method suitable for long tunnels and waterways with large water level fluctuations, and uses the ship traction system suitable for long tunnels and waterways with large water level fluctuations provided in the embodiment 1. The traction steps are as follows:

[0058] S1. According to the ship scheduling plan, the operator commands the navigation ship to sail from the upstream or downstream channel to the upstream or downstream tunnel portal and to be moored and tied at the ship pier by using the scheduling system.

[0059] S2. After the navigation ship is moored and tied at the ship pier of the upstream or downstream tunnel portal and is stopped, the staff controls the traction trolley 201 on both sides of the channel to run to the navigation ship at the upstream or downstream tunnel portal by using the remote control system 205, and adjusts the length of the traction cable 203 on both sides according to the ship size and the traction angle by using the cable winding and unwinding device 204, so that the output traction force of the traction trolley 201 on both sides is similar, and the difference between the two is within 5%.

[0060] S3. After the length of the traction cable 203 of the two sets of traction trolleys 201 is adjusted, the cable rings of the two traction cables 203 are hung on the traction piles on both sides of the ship.

[0061] S4. After the traction trolley 201 is connected with the ship, the ship is untied from the ship pier on the upstream or downstream, the traction trolley 201 is controlled to move on the walking track 7, and then the traction trolley 201 drags the ship to move in the channel.

[0065] The working principle of the present application: the present application is provided with a float box 1, and other devices can be arranged on the float box 1. When the water level in the channel fluctuates, the devices can move up and down synchronously with the float box 1, solving the problems of inconvenience in traction, braking, guiding and power supply and distribution when the navigation ship passes through the tunnel under the condition of large fluctuation of the water level in the channel. When the navigation ship sails through the hub navigation building, the traffic management department limits the ship sailing speed to 0.5-1 m / s. The present application can drive the navigation ship to sail at a speed of 3 m / s through the traction device 2, which doubles the speed of the ship entering and exiting the tunnel channel, shortens the time of the ship passing through the hub navigation building, and greatly improves the operation efficiency of the hub navigation building. The tunnel channel is a narrow and long closed space. If the ship passes through the tunnel channel by self-sailing, the ship exhaust and noise pollution are serious. The present application can remotely control the traction device 2 to drag the ship through the tunnel channel. The engine of the ship is stopped when entering and exiting the tunnel channel. Not only the ship exhaust and noise pollution are reduced, but also the ship operating cost is reduced.

[0066] In summary, the present application can effectively improve the safety and efficiency of the ship passing through the channel with long tunnel and large fluctuation of water level.

[0067] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
