For example, the motor drives the drum 1021 to rotate clockwise, the laying system 4 is placed into the seabed through the cable laying operation, and after the laying system 4 is sunk into the seabed, the tightness of the mooring cable 1022 is adjusted, so that when the operation and maintenance platform 1 drifts in a local area on the sea surface, the mooring cable 1022 between the operation and maintenance platform 1 and the laying system 4 is always in a loose state, the laying system 4 is prevented from being pulled out of the seabed, and the reliable operation of the offshore platform system is guaranteed. The motor drives the drum 1021 to rotate in a counterclockwise direction, and the deployment system 4 is lifted to the operation and maintenance platform 1 through the cable retracting operation. The driving member 1023 can also be a handle, and the winding drum 1021 is driven to rotate in a clockwise direction or a counterclockwise direction by rotating the handle, so as to realize the cable winding operation or the cable unwinding operation of the mooring cable 1022.
In the embodiment of the present invention, the mooring line 1022 is wound on the drum 1021, the free end of the mooring line 1022 is connected to the deployment system 4, and the driving member 1023 drives the drum 1021 to rotate, so as to drive the deployment system 4 to descend or ascend, so that the deployment system 4 can be submerged into the sea bottom or lifted to the operation and maintenance platform 1, which is beneficial to reducing the cost of operation and maintenance work and improving the convenience of operation and maintenance work.
As shown in fig. 1 to 4, in an alternative embodiment, the base 101 is provided with a first opening, the carrier 301 is provided with a second opening, and the first opening and the second opening are arranged opposite to each other in a vertical direction; the mooring line 1022 can be threaded through a first opening and a second opening for guiding the raising and lowering of the deployment system 4.
Specifically, the base 101 is provided with a first opening, the carrier 301 is provided with a second opening, and an orthographic projection of the first opening is located in an area where the second opening is located. The first opening is located right below the reel 1021, and during sinking of the deployment system 4, the mooring line 1022 passes through the area of the first opening and further passes through the area of the second opening until the deployment system 4 sinks to the target position on the seabed. Due to the mobility of the seawater, when the mooring line 1022 moves in the vertical direction, the mooring line 1022 may drift, and the movement trajectory of the mooring line 1022 may be deviated from the target trajectory. In the process of sinking the deployment system 4 or lifting the deployment system 4, the first opening and the second opening can limit the floating range of the mooring line 1022, guide the mooring line 1022 to move in the vertical direction, ensure that the deployment system 4 is accurately placed at the target position of the sea bottom, or stably lift the deployment system 4 to the operation and maintenance platform 1, and facilitate the convenience of operation and maintenance.
The first opening and the second opening are arranged oppositely in the vertical direction, so that the mooring rope 1022 can ascend or descend in the vertical direction, and meanwhile, the lifting mechanism 102 does not need to be suspended outside the operation and maintenance platform 1, and the compactness of the platform structure is facilitated.
As shown in fig. 1, 2 and 3, in an alternative embodiment, the seabed platform 3 further comprises a limiting member 304, and the limiting member 304 is disposed in the circumferential direction of the second opening and is disposed in an inclined manner at one side of the carrier 301.
Specifically, the second opening is U-shaped or trapezoidal, for example, the second opening is U-shaped, the second opening has three connected segments, the limiting member 304 is disposed at the second opening, and the limiting member 304 includes three limiting plates connected in sequence. The three limiting plates are respectively connected with the three sections of the second opening, the limiting plates are obliquely arranged on the top surface of the bearing piece 301, the three limiting plates are sequentially connected, and the three limiting plates and the second opening form a channel in a horn mouth shape. The area enclosed by the second opening and the stopper 304 can further limit the floating range of the mooring line 1022, so that the mooring line 1022 can move in the vertical direction, and the deployment system 4 can be stably raised or lowered in the vertical direction.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
