Depth-setting towed vehicle for underwater

Abstract

The invention relates to a depth-setting towed vehicle for underwater. The depth-setting towed vehicle comprises a main frame, an upper cover, a lower cover, wing plates and a tail rudder plate, wherein the upper cover and the lower cover are correspondingly arranged at the upper and lower ends of the main frame; the two wing plates are arranged correspondingly on the two sides of the main frame in the radial direction, and the ends, vertically arranged in the radial direction of the main frame, of the wing plates are perpendicular to the main frame; the tail rudder plate is arranged between the two wings plates, and the lower ends of the wing plates are fixedly arranged on the main frame; the upper cover includes a flow facing body and a flow guiding body, wherein the flow facing body andthe flow guiding body are arranged from left to right in the axial direction of the main frame in sequence; the lower cover includes a flow facing cover, a long frame cover and a flow guiding cover,wherein the flow facing cover, the long frame cover and the flow guiding cover are arranged from left to right in the axial direction of the main frame in sequence; and one ends of the flow facing body, the flow guiding body, the flow facing cover and the flow guiding cover are curved surfaces, the upper cover and the lower cover are matched with each other to form a hollow accommodation cavity, and the main frame is located in the accommodation cavity. The depth-setting towed vehicle can adapt to the deep sea of 2000 meters, while the stability of the attitude of the depth-setting towed vehicle can still be maintained, the depth-setting towed vehicle can adapt to the detection of the seabed at different depths, and the adaptability is high.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to an underwater depth-fixing drag body. Background technique [0002] One of the most important items in the detection of deep water environment is to obtain gravity and magnetic data (gravity field and magnetic force field). Accurate gravity and magnetic data can be used to establish gravity and magnetic charts for underwater navigation directly; 2) for offshore oil and gas exploration, gravity and magnetic detection mainly solves problems related to oil and gas geological structures, special lithology distribution, etc., and achieves the role of indirect search for oil and gas . In order to obtain high-precision gravity and magnetic data, a mobile measurement method can be adopted, that is, a towed method is adopted. The mother ship drags the towing body equipped with measurement equipment to conduct seabed detection, thereby obtaining gravity and magnetic data, and be...

Problems solved by technology

However, in the environment below 2000 meters in the deep sea, due to the structural reasons of the ordinary tow body, due to the shaking brought by the mother ship, the movement of the tow body towed by the mother ship often leads to the inability of the tow body to maintain a stable posture, coupled with the impact of sea currents on the tow body, As a result, the towing body often deviates greatly up and down, left and right, and shakes violently, which seriously affects the measurement accuracy of the measuring equipment; at the same time, the ocean at a depth of 2,000 meters exerts strong pressure on the towing body, requiring the towing body to have sufficient strength to withstand such pressure, so it is difficult for ordinary trailers to adapt to such a high-depth ocean environment
