[0034] A cable conveying mechanism 5 is installed on the hull 1, and the cable 7 conveyed by the cable conveying mechanism 5 is passed through the wiring assembly 3 and is located between the wiring assembly 3 and the wire pressing assembly 4;

[0036] Specifically, a hull 1 is provided, and a trenching mechanism 2 is movably installed at the end of the hull 1 along the traveling direction. A trench for laying a cable 7 can be dug in the underwater riverbed through the trenching mechanism 2. A wiring assembly 3 is installed on the trenching mechanism 2. A wire pressing assembly 4 is movably installed on the side of the wiring assembly 3 away from the trenching mechanism 2. A cable conveying mechanism 5 is installed on the hull 1. The cable 7 conveyed by the cable conveying mechanism 5 is passed through the wiring assembly 3 and is located between the wiring assembly 3 and the wire pressing assembly 4. The cable 7 is conveyed to the wiring assembly 3 through the cable conveying mechanism 5. The wiring assembly 3 cooperates with the wire pressing assembly 4 to smoothly guide the cable 7 into the trench dug by the trenching mechanism 2. In order to realize the wiring of the cable 7, a sediment collecting and backfilling mechanism 6 is also installed on the hull 1. The collecting end of the sediment collecting and backfilling mechanism 6 is arranged corresponding to the trenching mechanism 2, and the backfilling end of the sediment collecting and backfilling mechanism 6 is connected to the end of the wiring component 3 away from the trenching mechanism 2. The sediment collecting and backfilling mechanism 6 can collect the sediment excavated by the trenching mechanism 2 to prevent the sediment from spreading, and at the same time, the collected sediment can be backfilled into the trench excavated by the trenching mechanism 2 to realize the burial of the laid cable 7. In summary, the application of this device can realize the integrated operation of underwater trenching, cable 7 wiring and burial, thereby improving the laying efficiency of the underwater cable 7.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the trenching mechanism 2 includes a dredging support 201, one end of the dredging support 201 is hingedly connected to the hull 1, a chain 202 driven by a motor is installed on the dredging support 201, and a plurality of digging teeth 203 are arranged and installed on the chain 202. The chain 202 drives the digging teeth 203 to drive, thereby digging a trench for burying the cable 7 in the underwater riverbed;

[0038] A first pushing device 204 is connected between the dredging bracket 201 and the hull 1 to push the dredging bracket 201 into the underwater riverbed. One end of the first pushing device 204 is connected to the dredging bracket 201, and the other end is connected to the hull 1. The contraction of the piston rod in the first pushing device 204 can drive the dredging bracket 201 to extend underwater and contact the riverbed, thereby achieving trenching of the riverbed, which is convenient for the subsequent burial of the cable 7. At the same time, the depth of trenching by the trenching mechanism 2 can also be controlled to be suitable for waters of different depths.

[0039] In this embodiment, two groups of first pushing devices 204 are provided, which are respectively located on both sides of the dredging support 201. By providing two groups of first pushing devices 204, sufficient power is provided so that the dredging support 201 can be extended into the underwater riverbed.

[0040] like Figure 1 and Figure 3-Figure 5 As shown, in the embodiment of the utility model, the wiring assembly 3 includes a wiring track 301, which is fixedly mounted on the dredging support 201 through a first support frame 302. The wiring track 301 is provided with a groove for passing the cable 7. The cable 7 enters the groove excavated by the trenching mechanism 2 along the groove, thereby realizing smooth guidance and laying of the cable 7.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of the utility model, a re-grooving portion 303 and a cable introduction portion 304 are provided at one end of the wiring track 301 away from the hull 1. The re-grooving portion 303 is arranged corresponding to the trenching mechanism 2, and the cable introduction portion 304 is smoothly connected to the groove. The trench pre-dug by the trenching mechanism 2 can be re-grooved through the re-grooving portion 303. Because the pre-dug trench is prone to landslides and burials during underwater operations, the soft silt in the trench can be turned over through the re-grooving portion 303, and the cable 7 can be smoothly introduced into the turned-over trench through the cable introduction portion 304, so that the cable 7 can be buried to a predetermined depth position. In addition, the cable introduction portion 304 can allow the cable 7 to smoothly enter the trench on the riverbed from the groove, thereby ensuring the quality of the laying of the cable 7.

[0042] like Figure 1 , Figure 3 and Figure 4 As shown, in the embodiment of the utility model, the wire pressing assembly 4 includes a wire pressing bracket 401, one end of the wire pressing bracket 401 is hingedly mounted on the wiring track 301, and the other end of the wire pressing bracket 401 is rotatably mounted with a wire pressing roller 402, and a space for pressing the cable 7 is formed between the wire pressing roller 402 and the wiring track 301. The wire pressing roller 402 applies a force to the cable 7, so that the cable 7 can move along the wiring track 301, so that it can be smoothly laid in the groove;

[0043] A second pushing device 403 for adjusting the pressing force of the wire pressing roller 402 is connected between the wire pressing bracket 401 and the wiring track 301. One end of the second pushing device 403 is connected to the wire pressing bracket 401, and the other end is connected to the wiring track 301. The wire pressing bracket 401 can be driven to rotate by the extension and retraction of the piston rod in the second pushing device 403, thereby realizing the adjustment of the pressing force of the cable 7.

[0044] In addition, the first pushing device 204 and the second pushing device 403 may be hydraulic cylinders or pneumatic cylinders.

[0045] like Figure 1 and Figure 3 As shown, in some embodiments of the utility model, the sediment collection and backfilling mechanism 6 includes a sediment collection cover 601, which is installed on the hull 1. The sediment collection cover 601 is connected to the input end of the mud pump 602, and the output end of the mud pump 602 is connected to the mud discharge pipe 603. The mud pump 602 is driven by a driving mechanism, and the mud discharge pipe 603 is connected to the mud discharge hose 604. The mud discharge hose 604 is installed on one side of the wiring track 301, and the end of the mud discharge hose 604 away from the mud discharge pipe 603 is provided with a mud discharge port 605, and the mud discharge port 605 forms a backfilling end. The mud discharge port 605 is installed at the end of the wiring track 301 away from the hull 1. Therefore, the sediment excavated by the trenching mechanism 2 can be collected by the sediment collection cover 601 to avoid the diffusion of sediment. The collected sediment can be transported to the end of the wiring track 301 away from the hull 1 through the mud pump 602, the mud discharge pipe 603 and the mud discharge hose 604 to fill the laid cable 7.

[0046] like Figure 1 and Figure 3 As shown, in the embodiment of the utility model, the sediment collecting cover 601 is in a trumpet-shaped structure, and the large mouth end of the trumpet-shaped structure of the sediment collecting cover 601 is arranged toward the trenching mechanism 2 to form a collecting end. By setting the trumpet-shaped structure of the sediment collecting cover 601, the collection efficiency of the sediment can be improved and the diffusion of the sediment can be reduced.

[0047] like Figure 1 , Figure 3 and Figure 4 As shown, in an embodiment of the utility model, the cable conveying mechanism 5 includes a second support frame 501, the second support frame 501 is installed on the hull 1, and a conveying roller 502 driven by a driving device is relatively rotatably installed on the second support frame 501, and a space for squeezing and conveying the cable 7 is formed between the two conveying rollers 502. The cable 7 is conveyed by the two conveying rollers 502, so that the cable 7 is smoothly conveyed to the wiring track 301.

[0048] For ease of understanding, the working process of this embodiment is given below:

[0049] like Figure 1-Figure 5 As shown, first, the cable 7 is conveyed to the wiring track 301 through the two conveying rollers 502, and the wire is pressed by the wire pressing roller 402. The pressure of the wire pressing roller 402 is adjusted by controlling the extension and contraction of the second pushing device 403. Then, the dredging support 201 is driven to rotate downward and extend into the underwater riverbed through the contraction of the first pushing device 204. Since the wiring track 301 is installed on the dredging support 201 through the first supporting frame 302, the wiring track 301 is synchronously extended into the underwater riverbed with the dredging support 201. Then, the trenching mechanism 2 is started, and the motor drives the chain 202 to transmit. The chain 202 drives a plurality of digging teeth 203 to excavate the silt on the riverbed, and as the hull 1 moves The sludge collecting and backfilling mechanism 6 operates synchronously to collect the sludge excavated by the trenching mechanism 2 through the sludge collecting cover 601, and transports it to the sludge discharge port 605 of the sludge discharge hose 604 through the sludge pump 602 and the sludge discharge pipe 603. Since the sludge discharge port 605 is installed at the end of the sludge discharge track 301 away from the hull 1, the cable 7 laid in the trench can be buried, thereby realizing the integrated operation of underwater trenching, cable 7 wiring and burial.

[0050] In summary, the utility model provides an underwater cable laying vessel, which can realize the integrated operations of underwater trenching, cable wiring and landfilling.
