Embodiment Construction

[0038] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039]The invention provides a marine towed low-resistance fixed-depth gravity-magnetic detection tow body. The whole machine is designed with a modular concept, and modules can be added or subtracted according to needs; the appearance is designed to prevent torpedoes, which can greatly reduce the resistance in water; There are two horizontal wings, and the tail is equipped with four tail fins to make the towing body have good stability in water.

[0040] Such as figure 1 As shown, a marine towed low-resistance fixed-depth gravity-magnetic detection drag body proposed by the present invention includes a bow module 3, a main control cabin module 5, an antenna cabin module 9, a load cabin module 11, a tail cabin module 12 and a gravimeter cabin module 23;

[0041] The bow module 3 includes the bow cabin, the load-bearing head 1 and the...

Abstract

The invention discloses an ocean pull-type low-resistance fixed-depth gravity and magnetic detection towed body, and belongs to the field of ocean gravity and magnetic force measurement. In order to reduce dragging resistance and simulate the shape of a torpedo in appearance, the device comprises a bow module, a main control cabin module, a hydrofoil cabin module, a load cabin module, a stern cabin module and a gravimeter cabin module, all the modules are fixedly connected through flanges, and the modules can be increased or decreased according to task requirements. The bow module is provided with a bearing head and a fixed connecting rod, the trailing cable and the bearing head are vulcanized together, and a mother ship drags the towed body to advance in water through the trailing cable. The main control cabin is provided with a control communication module used for receiving and transmitting towed body attitude control instructions. An antenna is arranged on the upper side of the hydrofoil cabin, a DVL is arranged on the lower side, and balance hydrofoils are symmetrically installed on the two sides of the gravimeter cabin module. The load cabin is provided with detection equipment, and the tail cabin module is provided with four empennages which are arranged in a crisscross manner. Modular design is adopted, assembling is convenient, dragging resistance is low, posture stability is good, the problem that in the prior art, the posture stability of a towed body is poor is solved, and expandability of the towed body is improved.

Description

technical field [0001] The invention relates to a marine towed low-resistance fixed-depth gravity-magnetic detection tow body, which belongs to the technical field of marine detection equipment. Background technique [0002] Ocean detection technology has become a key area of ​​current international competition, among which ocean gravity and magnetic measurement has a wide range of applications in military and civilian fields, such as resource detection, earth science research, target detection, port monitoring, geomagnetic matching navigation and anti-submarine, etc. In order to obtain gravity and magnetic data (gravity field and magnetic force field data), a towed measurement method can be used, that is, the mother ship drags the towing body through the tow cable for detection. Traditional marine gravity and magnetic surveys are often carried out by carrying large-scale scientific research ships or frame-type tow bodies. Large-scale scientific research ships can only trave...
