A drag body suitable for diving areas

Abstract

The invention belongs to a drag body suitable for diving areas. A drag body suitable for diving areas includes a front body and a rear body. Both the front body and the rear body are hollow structures, and a seal is arranged in the front body cabin, the sealed cabin is provided with a front sealing cover and a rear sealing cover, the inner surface of the rear sealing cover is provided with a circuit board bracket, a counterweight frame is arranged between the sealed cabin and the inner wall of the front, and the counterweight The frame includes a number of counterweight spaces, a counterweight ring is arranged in the counterweight space, a hook plate is arranged on the outer wall of the front body, and a number of hook holes are arranged on the hook plate; in the present invention, the drag body is connected by a cable On the ship, the connection position can be determined according to the actual needs of the project; the position of the center of gravity can be adjusted by loading different numbers of counterweight rings around the airtight cabin, and the auxiliary rear body and tail fin can greatly improve the attitude stability of the drag body.

Description

technical field [0001] The invention belongs to the field of offshore, lake and river engineering, and in particular relates to a drag body suitable for diving areas. Background technique [0002] Underwater towing body is also called towing body. It is a kind of investigation equipment that is dragged behind the ship when the ship is sailing, and directly measures the water quality, terrain and other parameters related to the water body. It has been widely used in water quality monitoring and military and civilian surveys. Waiting for underwater detection. [0003] When the tow body is navigating in the diving area, the existence of external factors such as various ocean currents, underwater plants, and floating plants produces various forces such as vertical force, pitch force, and gravity, which make the tow body The attitude is unstable, and in turn, affects the detection effect of the underwater towed body. And the position of the center of gravity of the towing body ...

AI Technical Summary

Problems solved by technology

[0003] When the tow body is navigating in the diving area, the existence of external factors such as various ocean currents, underwater plants, and floating plants produces various forces such as vertical force, pitch force, and gravity, which make the tow body The posture is unstable, and in turn, affects the detection effect of the underwater towing body

And the position of the center of gravity of the towing body is not easy to adjust, and the working posture of the towing body cannot be adjusted as required
