Description

Technical Field

[0001] This utility model relates to the field of underwater operation equipment technology, specifically to a rock-throwing system and a rock-throwing vessel. Background Technology

[0002] Underwater rock dumping, as a traditional underwater facility protection measure, has been widely used in offshore oil development. Traditional rock dumping methods, involving direct rock dumping from ships, are highly susceptible to sea conditions and make it difficult to control the dumping location. A search revealed Chinese patent CN204919564U, which discloses a deep-water rock dumping device for connecting to a rock dumping vessel. Its features include a rock detection device, a retractable first rock dumping pipe, several second rock dumping pipes, and a third rock dumping pipe. The first, second, and third rock dumping pipes are sequentially connected to form a rock dumping pipeline for dropping rocks onto a seabed pipeline. The third rockfall pipe has several water inlet holes on its side; the rockfall detection device is installed on the first end of the first rockfall pipe away from the second rockfall pipe, and the rockfall detection device includes a body, a central channel located in the middle of the body and extending through the upper and lower ends of the body, retractable manipulators located on opposite sides of the body, a propulsion mechanism located within the body, and a detection system for locating and collecting pipeline-related information and transmitting the collected information to the data processing center on the rock-throwing vessel via an umbilical cable; the first end of the first rockfall pipe passes through the central channel. The shortcomings of the above patent are: First, when using the aforementioned patent, it is necessary to manually assemble the first rockfall pipe, the second rockfall pipe, the third rockfall pipe, and the rockfall detection device, and then place them into the water one by one. After use, it is also necessary to manually retrieve the first rockfall pipe, the second rockfall pipe, the third rockfall pipe, and the rockfall detection device one by one, which is time-consuming, labor-intensive, and cumbersome, increasing the operator's working time and costs. Second, when the aforementioned patent is not in use, the first rockfall pipe, the second rockfall pipe, the third rockfall pipe, and the rockfall detection device are stacked on the hull, occupying a large amount of hull space. Third, the deep-sea rock-throwing equipment in the aforementioned patent is located above the seabed, at a distance from the seabed. In addition, the complex seabed topography and dense vegetation increase the difficulty of observation, resulting in inaccurate landing positions of the rocks after they are thrown. Fourth, during the rock-throwing process, the rocks are easily affected by factors such as ocean currents and waves, causing the rocks to deviate from the expected position after they fall, which may require rework and result in low operational efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a stone-throwing system and stone-throwing vessel with a clever structure, automatic deployment and retraction, no need for disassembly and assembly, accurate stone-throwing position, and high operating efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A stone-throwing system, characterized in that it includes a support frame, on which a rapid stone-throwing and extending mechanism for a stone-throwing tube is provided.

The umbilical cable is fixedly connected to the cable connecting sleeve. Thus, the cable locking device enables the retrieval and release of the observation frame 24. Specific operating steps are as described in CN217801822U and will not be repeated here. The observation frame 24 is equipped with a thruster 6 and an observation component 25, allowing the observation frame 24 to freely adjust its attitude and position underwater after being released via the umbilical cable 29. (See attached...) Figure 7 and attached Figure 8 , attached Figure 8 From the appendix Figure 7 The enlarged view of the observation component 25, shown along the arrow direction, illustrates that the observation component 25 includes a lighting unit, a sonar, and a camera. Lighting units can be installed at both the upper and lower ends of the observation frame 25. The sonar and camera can be mounted on a pan-tilt unit, allowing adjustment of their angles to ensure proper scanning and imaging. Both the thruster 6 and the observation component 25 are connected to the control system on the observation frame 24. Both the control system on the observation frame 24 and the control system of the workboat can utilize PLC control systems. Before use, the rock-throwing system is installed on the hull 37 of the work vessel. After the work vessel reaches the rock-throwing operation area, the retraction and deployment components 4 on both sides of the rock-throwing detection device 6 work synchronously to lower the rock-throwing telescopic pipe 5 and the rock-throwing detection device 6 to the designated rock-throwing operation depth. Due to the complex seabed environment, the rock-throwing detection device 6 will be affected by the impact of water currents and produce significant swaying. The multiple thrusters fixed on the rock-throwing machine body 18 can effectively reduce the swaying amplitude of the rock-throwing machine body 18 during this complex operation. The rock-throwing detection device 6, through camera 33, can clearly and without blind spots capture the seabed conditions below. Based on the seabed conditions, the overall angle of the rock-throwing machine 18 is adjusted by the thruster to better complete the rock-throwing operation. After the rock-throwing machine 18 reaches the designated work area, the rock-throwing machine control system of the rock-throwing machine 18 opens the rock-throwing opening and closing cover 35 to complete the preparation work for the rock-throwing operation. In order to prevent the rock-throwing opening and closing components 34 from being damaged by falling rocks, the opening and closing drive cylinder 36 is placed behind the rock-throwing opening and closing cover 35 for protection. After the rock-throwing detection device 6 completes the preparation work, the conveying hopper 11 moves above the rock-throwing telescopic pipe 5 and locks the guide rail clamp 15 to prevent the conveying hopper 11 from moving during the operation. At this time, the rock-throwing operation begins, and the stones can be manually fed. The stone is fed into the conveying hopper 11, or a conveying device is set on one side of the conveying hopper 11. The conveying device can be an existing conveying device, as long as it can automatically transport the stone to the conveying hopper 11. The conveying device can be fixed on the work boat. The way the stone enters the conveying hopper 11 can be selected and set according to the requirements. The stone enters the uppermost stone throwing pipe of the stone throwing telescopic pipe 5 through the conveying hopper 11 and the conveying channel 12, and then falls into the designated area on the seabed along the stone throwing pipe to complete the stone throwing operation. After the operation is completed, the steel wire rope 20 is retrieved by the release and recovery component 4, which causes the stone throwing detection device 6 to rise slowly and drives the stone throwing retraction pipe 5 to retract automatically. After the steel wire rope 20 is completely retrieved, the stone throwing telescopic pipe 5 and the stone throwing detection device 6 are completely retrieved into the storage frame 3, thus completing the stone throwing operation. Compared with existing technologies, this utility model can start operation without assembly or hoisting before use, and can be directly recycled into the storage frame 3 after operation. This reduces the processes of assembly and hoisting before operation and recycling and disassembly after operation, shortens the time at sea, and improves work efficiency. This utility model is equipped with a multi-angle observation mechanism 23, and the observation frame 24 can move freely relative to the stone-throwing machine body 18. The stone-throwing machine body 18 is closer to the stone-throwing operation area. From the side of the stone-throwing machine body 18 and the seabed operation area, the seabed operation area and the falling rocks can be observed from multiple angles and directions, which improves the positioning accuracy of the stone-throwing operation area, timely corrects the throwing position, and improves the efficiency of stone-throwing operation.

[0046] This utility model, due to the above-mentioned structure, has the advantages of ingenious structure, automatic retraction and extension, no need for disassembly and assembly, accurate stone throwing position, and high work efficiency.
