Description

Technical Field

[0001] The utility model belongs to the technical field of marine resource exploration equipment, and in particular relates to a near-bottom seabed towed body used in the deep sea. Background Art

[0002] At present, the most widely used method in deep-sea energy and mineral resource surveys and explorations is acoustic detection. Its principle is to excite sound waves of a certain frequency band to the seabed near the seabed, and then receive the echo reflected by the seabed strata through the hydrophone array, and infer the distribution of deep-sea seabed energy and minerals based on the echo characteristics. The deep-sea near-bottom towed body can continuously, quickly and over a large area measure various marine elements during navigation, and is an important means of seabed detection. The working water depth of the towed body directly affects the seabed area and depth range that the towed body can detect.

[0003] The working water depth of the towed body equipped with the spark source is mostly 2000 meters. Increasing the working depth of the spark source requires a powerful power supply and sufficient energy reserve, and will also increase the volume of the spark source. In the prior art, Chinese invention patent CN112389612B provides a deep-sea towed body emergency obstacle avoidance mechanism and its control method. The deep-sea towed body provided by the patent includes a two-layer structure, the upper layer is used to install the control device, and the lower layer is used to install the instrument cabin. On this basis, when increasing the working water depth of the spark source, if the size of the lower frame is simply increased, the structural stability of the towed body will be reduced, affecting the operational flexibility of the towed body on the seabed, and the working water depth of the towed body cannot be increased adaptively.

The offshore towed body for deep sea provided by the utility model can effectively increase the working water depth of the electric spark source 3 by fixing the control cabin 110 and the power supply cabin 301 at the upper and lower parts of the upper frame 1 respectively, and accommodating the discharge cabin 302 and the gas storage cabin 303 in the lower frame 2, instead of simply increasing the size of the lower frame 2, thereby avoiding the problem of reduced structural stability;

[0075] 2. The offshore towed body for deep sea provided by the utility model forms a containing space inside the upper tube frame 102 and the lower tube frame 202, and reasonably arranges the positions of the control cabin 110, the power supply cabin 301, the discharge cabin 302 and the gas storage cabin 303, thereby optimizing the utilization of the internal space of the towed body and improving the integration and working efficiency of the equipment;

[0076] 3. The near-bottom towed body for deep sea provided by the utility model makes the maintenance of the towed body and the adjustment of the movement state more convenient through the detachable design of the side fixing plate 103 and the setting of the through hole, thereby improving the convenience and flexibility of operation;

[0077] 4. The near-seabed towed body for deep sea provided by the utility model improves the manufacturing and assembly efficiency of the towed body by designing each component as a detachable component and utilizing a modular design concept, and is easy to disassemble and move when necessary, thereby realizing resource reuse.

[0078] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0079] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
