All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-5 shown, a launching barge anchoring arrangement system is provided. During the traditional operation of the launching barge, when the ship enters and exits the launching barge in a specific water area, it is necessary to frequently drop the anchor. In this case, the launching barge is arranged in a fixed water area, that is, at a fixed dock pit position, and a corresponding fixed launching barge anchoring system is designed and arranged. This system can be continuously used at the fixed water area position, with simple operation, safety and reliability, avoiding the reduction of operation efficiency caused by repeatedly moving the launching barge, and eliminating the unsafe accidents caused by the frequent dropping and positioning of the launching barge. At the same time, the anchoring is arranged at the fixed dock pit position, improving the water area environment for the operation of the launching barge and enhancing the operation stability of the launching barge.

[0032] A launching barge anchoring arrangement system is applied during the process of a ship entering and exiting the launching barge 200 and the launching barge 200 performing floating and sinking operation tasks, and operates in a specific water area. This anchoring arrangement system includes a dock platform 100, a dock pit 110, a launching barge 200, a concrete sinker 300, a buoy 400, an anchor chain 500, and an anchoring device 600. Among them, the launching barge 200 is docked near the dock platform 100, and the safety distance between the two is about 1 - 3 meters. A dock pit 110 is provided at the corresponding water area position below the launching barge 200.

[0033] As Figure 2As shown, the length and width of the launching barge 200 are L and B respectively. In this case, the main body of the launching barge 200 is one with a length L = 95m and a width B = 38.5m. The main body of the launching barge 200 consists of a floating box and 4 buoyancy towers arranged at the four ends of the floating box. In this case, the tower is 12.5m long, 2.1 / 3.2m wide, and 13.6m high, and the hull is of all-welded structure.

[0034] As Figure 1 、 Figure 2 As shown, a launching barge anchoring arrangement system has a dock platform 100 arranged in a selected water area. The arrangement position of the dock platform 100 takes into account the convenience of ship docking, construction, good water area environment, and convenience for underwater excavation of the dock pit 110; the length and width of the dock pit 110 are respectively greater than the length and width L and B of the launching barge 200, approximately (L + 10) meters long and (B + 10) meters wide. The depth of the dock pit 110 needs to meet the requirement of the maximum sinking depth D of the launching barge 200, approximately (D + 1) meters, where the depth is the depth below the zero tide level of the tide.

[0035] As Figure 1 As shown, the launching barge 200 is fixedly arranged at the corresponding position of the dock pit 110. The length, width, and depth of the position of the dock pit 110 all meet the operation of the launching barge 200 in this fixed water area. The launching barge 200 conducts operations such as ship entry and exit and its own floating and sinking at the position of the dock pit 110.

[0036] As Figure 1As shown in the figure, a mooring and anchoring system for a launching barge is designed to adopt a four-point mooring and a three-point anchoring system for the launching barge 200. The upstream two ends of the launching barge 200 are designed with a cross-anchoring system, and the downstream is designed with a convergent-anchoring system. It provides a stable mooring and fixing construction environment for the launching barge 200; the launching barge 200 is fixedly arranged at the position of the dock pit 110. Affected by the hydrological environment of the water area at this place, the launching barge 200 needs to be anchored and fixed to avoid the influence of factors such as water flow, wind, and waves, and maintain the stable operation state of the launching barge 200 in this water area. The launching barge 200 is floating and fixedly arranged at the corresponding position of the dock pit 110. The head and tail of the launching barge 200 are fixed by anchor chains 500. One end of the anchor chain 500 is fixed at the head and tail positions of the launching barge 200, and the other end is fixed on the underwater concrete sinker 300. The arrangement method of the anchor chain 500: At the upstream of the dock pit 110 and the tail of the launching barge 200, a double-anchor-chain 500 cross-fixing method is adopted. One end is cross-fixed to the launching barge 200, and at the same time, the other end is respectively cross-fixed to two underwater concrete sinkers 300, so that the launching barge 200 is not affected by external factors such as water flow, wind, and waves and drifts downstream and laterally; at the downstream of the dock pit 110 and the head of the launching barge 200, a double-anchor-chain 500 fixing method is adopted. One end is fixed to the launching barge 200, and at the same time, the other ends of the double-anchor chains 500 converge and are fixed through the same floating buoy 400. The single floating buoy 400 is fixed on a single underwater concrete sinker 300, so that the launching barge 200 is not affected by external factors such as wind and waves and drifts laterally. By respectively fixing the root anchor chains 500 at the head and tail positions of the launching barge 200, the upstream and downstream and lateral drifts of the launching barge 200 are effectively controlled.

[0037] The anchor chain 500 adopts an anchor chain with a diameter of 40 - 52 mm, and the length is selected as 1 - 1.5L, that is, 1 - 1.5 times the length of the launching barge 200; the floating buoy 400 is purchased and matched. Each concrete sinker 300 is selected as an 80 - 120-ton concrete sinker.

[0038] As Figure 2 、 Figure 3 、 Figure 4 As shown in

[0039] As Figure 4 、 Figure 5As shown in the figure, the design adopts a four-terminal mooring arrangement system for the launching barge 200 and simple anchoring equipment 600, which are respectively designed and installed at both ends of the rear end wall 220 and the front end wall 230 of the floating box of the launching barge, with a quantity of 4 sets, 2 sets for each of the rear end wall 220 and the front end wall 230 of the floating box of the launching barge. Each set of anchoring equipment 600 is fixed on the bow and stern positions of the deck 210 of the floating box of the launching barge. The anchoring equipment 600 includes: a guillotine chain stopper 610 and a fairlead 620. The guillotine chain stopper 610 is welded and fixed on the bow and stern positions of the deck 210 of the floating box of the launching barge. The anchor chain 500 is connected to the guillotine chain stopper 610 and then turns vertically downward by 90 degrees and passes through the fairlead 620. The fairlead 620 is welded and fixed on the rear end wall 220 and the front end wall 230 of the floating box of the launching barge and is led below the water surface, and is respectively connected to the water area buoy 400 and the concrete sinker 300.

[0040] For the anchoring equipment 600, it is designed to use the guillotine chain stopper 610 to connect and fix the anchor chain 500 and use the fairlead 620 to convert the export direction of the anchor chain 500. The guillotine chain stopper 610 is welded and fixed at the bow and stern edge positions of the deck 210 of the floating box of the launching barge, which is convenient for the turning of the anchor chain 500 and is beneficial to the protection of the anchor chain 500 at the corner. The height h of the deck 210 of the floating box of the launching barge is 5.4 meters in this case. The fairlead 620 is designed and installed on the rear end wall 220 and the front end wall 230 of the floating box of the launching barge, and the welded fixed height d is 0.5 meters in this case.

[0041] For the anchoring equipment 600, it is designed and arranged as close as possible to the outer sides of the rear end wall 220 and the front end wall 230 of the floating box of the launching barge, and the distance C from the outer side is minimized. In this case, the designed C value is about 9 meters. This design closer to the outside is more beneficial to reducing the floating and swaying of the launching barge 200.

[0042] For the anchoring equipment 600, it is designed to use the guillotine chain stopper 610 to connect and fix the anchor chain 500 and use the fairlead 620 to convert the export direction of the anchor chain 500. The guillotine chain stopper 610 is a cast steel guillotine chain stopper, and its specification matches that of the anchor chain 500, that is, it matches the anchor chain 500 with a diameter of 40 - 52 mm. The fairlead 620 also matches the anchor chain 500. In this case, the SWL205t specification is selected.

[0043] The rest of this embodiment is the same as that of Embodiment 1. For the features not explained in this embodiment, the explanations of Embodiment 1 are adopted and will not be elaborated here.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
