Description

TECHNICAL FIELD

[0001] The utility model relates to underwater laying technology field, concretely relates to a big length detection system underwater laying device. BACKGROUND

[0002] The traditional underwater detection system mainly contains kevlar cable, floating body material, float, anchor chain, anchor body, instrument equipment etc. parts, when laying, need to connect the floating body material, float, instrument through kevla cable in proper order and lay to the sea surface in proper order, make it in a straight line on the sea surface through the operation mother ship, then connect through the anchor chain and anchor body, lay the anchor body to the sea, through the self weight of anchor body, lay the whole detection system to the sea bottom, and anchor. This method is long in deck laying time, and the laying process is complex, and the laying process is easy to damage the laying system, and the falling point of the anchor body under water cannot be accurately controlled. The utility model optimizes the underwater laying method of the detection system and provides a big length array system laying device, which realizes accurate laying of the array system.

[0003] The water surface launching type is the most main submarine marker laying method at present, and is widely used at home and abroad, and is mainly used for the submarine marker with large array length. The water surface launching type adopts the method of marker first and anchor later, first throws the float and mooring cable etc. on the upper part of the deep sea submarine marker system into water in proper order, makes it gradually spread on the water surface under the action of sea current or ship progress. Finally, the anchor with large weight at the bottom is hoisted into water, and the whole submarine marker system sinks into water under the gravity of anchor, and is finally anchored to the sea bottom, and the laying of the submarine marker system is completed.

[0004] When the submarine marker system is launched in the sea operation, the method of marker first and anchor later is generally used. Through this method, although the release position of the gravity anchor is above the planned launching point, due to the dragging effect of sea current and submarine marker system, the movement track of the gravity anchor after release is uncontrollable, so that the gravity anchor cannot accurately land at the predetermined launching position, and the actual position of the submarine marker launching deviates. In order to meet the requirement of accurate laying, the researchers of the first marine research institute of the ministry of natural resources designed a deep sea submarine marker point laying method based on winch.

[0005] The main device used in the deep sea submarine marker point laying based on winch contains the submarine marker main float and the gravity anchor, the gravity anchor is connected with the submarine marker main float through the anchor mooring rope, the anchor mooring rope is provided with the anchor mooring system connected through the connecting piece, one end of the anchor mooring system is connected with the submarine marker main float through the shackle.

[0006] In order to realize accurate laying, first, the subject of the submarine to be laid is transported to the launching point; then, the submarine main float body connected by the crane cable and the acoustic release system is lifted, so that the anchor line is in a substantially vertical state, and in the actual working process, the winch can be matched with the tail crane to work; then, the crane cable is released, so that the submarine main float body sinks, and in this process, in order to ensure the laying accuracy, the tail crane and the winch can be controlled to slow down the sinking speed of the submarine main float body. After descending for a distance or for a period of time, the position of the submarine main float body is adjusted in time according to the deviation between the position of the submarine main float body received by the ultra-short baseline receiver and the position of the launching point; the adjustment of the position of the submarine main float body is mainly realized by the crane. When the distance between the gravity anchor and the launching point is less than a preset value, the submarine main float body is released through the acoustic release system; generally, when the position of the submarine main float body is stably above the planned launching point and the distance between the gravity anchor and the seabed is 5-10 m, the acoustic release system below the hook of the tail crane is operated to open the release hook and release the submarine system to complete the launching. Because the position of the system can be viewed in real time on the crane by means of the ultra-short baseline system when the hook is released, and the distance between the gravity anchor and the seabed is relatively short, the time required from the hook release to the landing of the gravity anchor is very short, so the position movement caused by the external environment such as sea current in this process is very small, so the purpose of high-precision fixed-point laying can be achieved. Finally, the final position of the submarine main float body is recorded after the gravity anchor lands.

[0007] The advantage of the submarine laying by the water surface launching type is that the requirement of the water surface mother ship support system is low, the laying of the submarine with a large array length can be adapted, and there is no limitation on the depth of the laying sea area, and the disadvantage is that the submarine laying process is complicated, and the submarine landing point position cannot be controlled.

[0008] The advantage of the submarine laying by the winch lifting type is that the laying point position can be actively adjusted, and the control precision of the submarine landing point position is high, and the disadvantage is that the submarine with a large array length is not suitable for the laying. In addition, the winch lifting type has high requirements on the bearing performance of the structure of the submarine itself, and is not suitable for the submarine with precise detection or communication cables.
