Description

Technical Field

[0001] The invention relates to the technical field of floating clearing, and in particular to a floating clearing boat tying operation system and method. Background Art

[0002] The use of mechanized floating cleaning boats is an important method to improve the efficiency of floating cleaning operations in front of the Three Gorges Reservoir Dam. Mechanized floating cleaning boats save time and effort, but the capacity of the boats is limited, and the floating objects salvaged need to be transferred in time. There are two traditional operation methods: one is that when the floating cleaning boat is full of floating objects, the floating cleaning boat docks to unload, and then returns to the floating cleaning operation waters to continue operations; the other is that while the floating cleaning boat is operating, a transfer boat (transfer boat) is on standby next to the floating cleaning waters. After the floating cleaning boat is full of floating objects, the floating cleaning boat leaves the floating cleaning waters, the transfer boat starts and docks with the floating cleaning boat, and the floating objects are transferred in time. Then the floating cleaning returns to the floating cleaning waters for operation, and the transfer boat docks and returns to standby again after the transfer is completed. These two operation methods are inefficient, and in the second method, the floating cleaning boat and the transfer boat are not tied together when docking, which is prone to safety accidents, and the engine of the transfer boat is repeatedly started and stopped during the entire operation, which consumes a lot of energy. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a floating clearing boat tying operation system and method. By adopting the above system, the operation efficiency of the floating clearing boat can be improved under the premise of ensuring safety and reducing energy consumption.

[0004] In order to achieve the above technical features, the object of the present invention is achieved as follows: a floating cleaning boat tying operation system, comprising a floating cleaning boat, on which a transverse belt conveyor for transporting floating objects is provided; a first mooring winch is provided on one side of the bow of the floating cleaning boat, a second mooring winch is provided on one side of the stern located on the same side of the first mooring winch, and a third mooring winch is provided on the other side of the stern;

[0005] The invention also includes a drift transfer boat, wherein a first mooring bollard and a second mooring bollard are symmetrically arranged on one side of the bow of the drift transfer boat, and a third mooring bollard is arranged at the stern of the drift transfer boat and on the same side as the first mooring bollard;

[0006] The first mooring winch is connected to the second mooring bollard via a bow cable;

[0007] The second mooring winch is connected to the first mooring pile via a waist cable;

[0008] The third mooring winch is connected to the third mooring pile via a tail cable.

[0009] The bow cable forms an angle A with the longitudinal direction of the ship from the bow of the floating clearing ship to the rear.

[0010] The tail cable forms an angle B with the longitudinal direction of the ship from the middle of the stern of the floating clearing ship.

[0011] The included angle A is 45°.

[0012] The included angle B is 45°.

[0013] An operation method of a debris cleaning ship mooring operation system includes the following steps:

[0014] Step 1, connection operation between the debris cleaning ship and the debris turning ship:

[0015] After the debris turning ship approaches the debris cleaning ship, the debris cleaning ship takes the bow cable, waist cable and stern cable in sequence, and each cable is taken onto the winch;

[0016] The bow cable extends from the bow of the debris cleaning ship backward at an angle A with the longitudinal direction of the ship, and exits to the second mooring bitt on the outer string side of the bow of the debris turning ship;

[0017] The waist cable exits from the stern of the debris cleaning ship to the first mooring bitt on the inner string side of the bow of the debris turning ship;

[0018] The stern cable forms an angle B with the longitudinal direction of the ship at the middle of the stern of the debris cleaning ship, and exits to the third mooring bitt on the inner string side of the stern of the debris turning ship; The stress conditions of each cable between the debris cleaning ship and the debris turning ship shall be observed at any time, and if there is any abnormality, it shall be reported to the bridge immediately;

[0019] Step 2, operation of transferring floating objects on the debris cleaning ship:

[0020] Winch in the waist cable of the debris cleaning ship until the center line of the transverse belt of the transverse belt conveyor on the debris cleaning ship is aligned with the loading area at the tail of the cabin of the debris turning ship, then tighten the bow cable, waist cable and stern cable to make the two ships closely lean against each other, and load the floating objects in a way from the back to the front;

[0021] Step 3, shifting operation of the debris turning ship:

[0022] When the first pile of floating objects on the debris turning ship is loaded enough, the debris cleaning ship shall stop salvaging and retract the transverse belt conveyor, start the second mooring winch to tighten the waist cable to move the debris turning ship backward until the transfer device is aligned with the adjacent empty space in front of the loaded floating objects in the cabin of the debris turning ship, tighten each cable, fix it on the mooring bitt, extend the transverse belt conveyor, and continue loading; During the loading process, the floating state of the debris turning ship shall be observed at any time to prevent the center of gravity from shifting;

[0023] Step 4, full-load operation of the debris turning ship:

[0024] After the debris turning ship is fully loaded, the debris cleaning ship retracts all debris cleaning devices and exits the operation area to a wide and flat water area to stabilize the ship position;

[0025] Step 5, untying operation of the debris turning ship:

[0026] The debris cleaning ship releases the stern cable and retrieves it above the water surface without throwing the end of the stern cable into the water. After the safe retrieval of the stern cable, the debris cleaning ship unties and retrieves the bow cable and the waist cable, and the turning debris ship separates from the debris cleaning ship, completing the mooring operation.

[0027] In the second step, a cable is led out from the bow and the stern of the debris cleaning ship and tied to the bollards of the two ships respectively, tightened and fastened as a safety cable to assist in operation.

[0028] The beneficial effects of the present invention are as follows:

[0029] 1. By adopting the above system, the operation efficiency of the debris cleaning ship can be improved on the premise of ensuring safety and reducing energy consumption.

[0030] 2. By adopting a 45° angle, the best connection effect is ensured. Description of the Drawings
