Description

Technical Field

[0001] This invention relates to the field of anchorage dredging technology, specifically to a barge departure guidance and positioning device. Background Technology

[0002] Anchorage dredging refers to the clearing and maintenance of anchorages to improve their service capacity for large vessels, ensure waterway safety and port operational efficiency. Anchorage dredging platforms are floating distribution stations located in anchorage areas far from the shore, specifically designed to receive sludge pumped from long distances and transfer it to transport barges.

[0003] When a barge is leaving the dredging platform, if the bow is against the water, the bow line should be released first. After the bow is at a small angle to the current, the rudder should be used appropriately to create sufficient lateral distance between the barge and the platform before increasing power to leave the platform. If the stern is against the water, the stern line should be released first. After the stern is at a small angle to the current, the bow line should be released. Then, the rudder should be used appropriately to create sufficient lateral distance between the barge and the platform before increasing power to leave the platform. However, both methods require the barge's own power to cooperate with the tidal operation, as the platform itself cannot provide active support for the departure of the barge.

[0027] The unberthing auxiliary mechanism includes: an upper support shell 401, a drainage manifold 402, an unberthing water pump 403, an inlet manifold 404, a drainage nozzle 405, an inlet conduit 406, a filter screen 407, a flow pipe 408, a lower support shell 409, and a second buffer pad 410. The upper support shell 401 is fixedly installed on the outside of the sealing seat 101 to support the drainage manifold 402. The drainage manifold 402 is fixedly installed inside the upper support shell 401. The outgoing waterway pusher barge has an unberthing pump 403 fixedly installed inside the upper support shell 401, located below the drainage manifold 402, for pumping water. An inlet manifold 404 is fixedly installed at the input end of the unberthing pump 403 to collect the water flow from the inlet pipe 406. A drain nozzle 405 is fixedly inserted between the upper support shell 401 and the drainage manifold 402 to drain the water. The inlet pipe 406 is fixedly inserted into the inlet manifold. The bottom of the inlet manifold 404 guides seawater into the inlet manifold 404. A filter screen 407 is fixedly installed at the bottom end of the inlet pipe 406 to filter seawater. A flow pipe 408 is fixedly installed between the output end of the offshore pump 403 and the drainage manifold 402 to transport water. A lower support shell 409 is fixedly installed between the lower surface of the upper support shell 401 and the sealing seat 101 to support the second buffer pad 410. The second buffer pad 410 is fixedly installed on the lower support shell 404. The outer surface of 09 forms a buffer between the barge and the lower support shell 409 when berthing. Through the upper support shell 401, drainage manifold 402, berthing pump 403, water inlet manifold 404, drainage nozzle 405, water inlet pipe 406, water filter screen 407, flow pipe 408, lower support shell 409 and second buffer pad 410, when the barge unfolds at an angle of attack to berth, the berthing pump 403 generates an outward push water flow to assist seawater in pushing the barge away from the platform.

[0028] Working principle: When the water jet pushes the boat, the unberthing pump 403 is started to draw seawater from the inlet pipe 406. At the same time, it will intercept and filter large particles of impurities when passing through the filter screen 407. Then, the seawater flows through the inlet manifold 404 and enters through the input end of the unberthing pump 403. Then, it is pushed by the unberthing pump 403 through the output end into the flow pipe 408. Then, it is pumped along the flow pipe 408 into the drainage manifold 402 and then sprayed out from the drainage nozzle 405. When the pusher arm 202 is pushed outward, the pusher arm motor 304 is started. The pusher arm motor 304 drives the threaded push rod 303 to rotate. When the threaded push rod 303 rotates, it pushes the threaded push-pull cylinder 301 to extend outward. When the threaded push-pull cylinder 301 extends outward, it pushes the pusher arm 202 through the pusher arm connecting rod 302 and the pusher arm pin 205, so that the pusher arm 202 rotates outward around the axis, thereby causing the fulcrum roller 203 and the buffer tire 204 to tilt outward, thereby pushing the bow or stern to tilt outward to meet the current. When the pusher arm 202 is reset, the pusher arm motor 304 is started to rotate in the opposite direction, so that the threaded push rod 303 reverses and pulls the threaded push-pull cylinder 301 to retract. When the threaded push-pull cylinder 301 retracts, it pulls the pusher arm 202 through the pusher arm connecting rod 302 and the pusher arm pin 205, so that the pusher arm 202 rotates inward around the axis until it is stored inside the arm retraction groove 207. Before leaving the berth, the barge is moored outside the sealing seat 101, and the mooring lines are fixed to the tying roller 102 and the tying guardrail 105. If the bow is against the water when leaving the berth, the cables fixed to the surface of the rigging guardrail 105 should be loosened first. Then, the pusher arm 202 near the bow should be activated and the bow cable released, causing the pusher arm 202 on the same side as the bow cable to tilt outward. The pusher arm 202 pushes the bow outward around the rigging roller 102 at the stern via the pivot roller 203, so that the bow actively faces the current. After the bow faces the current at a small angle, the stern cable is released and the leaving pump 403 is activated. The leaving pump 403 drives water to spray from the drainage nozzle 405. The water sprayed from the drainage nozzle 405 pushes the barge outward. Then, the rudder, in conjunction with the water sprayed from the drainage nozzle 405, opens up a sufficient lateral distance between the barge and the platform. Finally, the power is increased to move away from the platform. If the stern is facing the water when leaving the berth, the cables fixed to the surface of the rigging guardrail 105 should be loosened first. Then, the pusher arm 202 near the stern should be activated and the stern cable released, causing the pusher arm 202 on the same side as the stern cable to tilt outward. The pusher arm 202 pushes the stern outward around the rigging roller 102 at the bow via the pivot roller 203, so that the stern actively faces the current. After the stern faces the current at a small angle, the bow cable is released and the leaving pump 403 is activated. The leaving pump 403 drives water to spray from the drain nozzle 405. The water sprayed from the drain nozzle 405 pushes the barge outward. Then, the rudder, in conjunction with the water sprayed from the drain nozzle 405, increases the lateral distance between the barge and the platform, and then the power is increased to move away from the platform.
