Description

Technical Field

[0001] The utility model relates to the technical field of deep sea exploration, in particular to an anchoring system for deep sea deployment. Background Art

[0002] Currently, ocean exploration continues to extend to the seabed. Due to the influence of the deep-sea environment, such instruments and equipment are difficult to deploy and recover. Traditional detection instruments are deployed by placing the instrument in a single frame and lowering it directly to the seabed with a cable. However, many detection instruments are now required to be deployed at a certain depth on the seabed. The instrument needs to be suspended in a fixed position, which requires a set of anchoring systems. This type of system has many components and cannot be assembled after being lowered individually. It is usually deployed as a whole in a series mode. The spacing between each component is large, which can reach up to a kilometer. If they are deployed one by one, multiple deployment ships will be required to cooperate, which is risky and extremely costly. How to achieve economical and efficient deployment is a major difficulty. Utility Model Content

[0015] The following is a detailed description of the deep-sea anchoring system proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clarify the description of the embodiments of the present invention.

[0016] The utility model provides an anchoring system for deep-sea deployment, which is used for installing, carrying, deploying and recovering various types of ocean detection equipment and has the characteristics of high efficiency, economy, miniaturization, lightness and high adaptability.

[0017] like Figure 1As shown, the anchoring system includes a bottom anchor point frame 1, a transmission cable 2, an equipment installation frame 3 and a buoyancy supply system 4; the bottom anchor point frame 1 and the equipment installation frame 3 are connected by a transmission cable 2, and the equipment installation frame 3 and the buoyancy supply system 4 are connected by a steel cable.

[0018] The structure of the seat bottom anchor point frame 1 is as follows Figure 2 As shown, it includes a main frame 11, a load-bearing joint 12, an external connecting cable 13, a handrail 14, a support leg 15, and a protective net 16. The main frame 11 is located on the seabed and is used to install and carry various detection equipment, electronic cabins, etc., and serves as the bottom anchor point of the entire system; the load-bearing joint 12 is fixed above the main frame 11, and is used to connect the transmission cable 2 to the main frame 11, and to withstand the lifting force and suspension force; the external connecting cable 13 is used for connection with the external interface; the handrail 14 is installed on the outside of the main frame 11, and is used for grasping and supporting the underwater robot ROV when it is working. The underwater robot needs a support to work in the water, otherwise it cannot exert force; the support leg 15 is located below the main frame 11 to slow down the settlement of the main frame 11 on the seabed; the protective net 16 is used to protect the equipment carried inside the main frame 11.

[0019] The transmission cable 2 is used for the transmission of signals, electricity, etc., and bears the gravity of the main frame during hoisting, and bears the positive buoyancy and torsional force of the system during suspension.

[0020] like Figure 3 As shown, the equipment installation frame 3 includes a first frame 31, a second frame 33, and a load-bearing joint 33. The load-bearing joint 33 is used to connect the transmission cable 2 to the equipment installation frame 3 and withstand the lifting force and suspension force. The first frame 31 and the second frame 32 are both used to install and support the detection equipment. The two frames are connected in series and fixed with bolts. The number of series frames can be increased or decreased according to the equipment usage needs.

[0021] like Figure 4 As shown, the buoyancy supply system 4 includes a first float 41, a second float 42, and a float frame 43. The float frame 43 is used for float installation and must withstand significant lifting forces while providing positive buoyancy for suspending the equipment mounting frame 3. The first and second floats 41, 42 are used to suspend the entire system below sea level during deployment, pre-connecting the system in series in the seawater as a single entity. The suspension points are then attached to the float frame 43, and the first and second floats 41, 42 are removed, allowing the system to be deployed as a single entity. The number of floats can be adjusted based on the weight of the system equipment to adjust the positive buoyancy.
