Embodiment 1

[0025] A diversion device for enhancing the posture stability of an underwater towed body. The towed body 1 is dragged by a survey ship 2. There is a diversion device behind the towed body 1. The diversion device includes a cone with a large inlet and a small outlet to stabilize the water flow. Drain tube 3.

[0026] The tapered draft tube 33 is connected to the retracting mechanism 5 through the tow cable 4 , and the retracting mechanism 5 is fixed at the tail of the dragging body 1 .

[0027] The receiving mechanism is also provided with a controller and a flow rate detector connected to it, and the controller is connected with the main control system on the measuring ship 2 through the photoelectric composite cable on the towing body.

[0028] The outlet of the draft tube is provided with an outlet regulator, which includes a tapered regulating cylinder 34 that is connected in sections and whose inlet and outlet are successively reduced. The tapered regulating cylinders 34 ...

Abstract

The invention discloses a diversion device for improving posture stability of an underwater dragged body. The dragged body is dragged by a measuring ship, and the diversion device is dragged behind the dragged body and comprises a conical diversion pipe with a big inlet and a small outlet and enabling water flow to be stabilized. By arranging the conical diversion pipe, a relative steady-flow area can be realized at the inlet of the conical diversion pipe, the posture stability of the underwater dragged body can be enhanced better. Both the inlet and the outlet of the conical diversion pipe can be adjusted in size, especially the inlet can be adjusted in real time, and size of an opening of the conical diversion pipe can be controlled according to speed of the ship and water flow to enable the dragged body to be constantly in the steady-flow area, so that the posture stability of the dragged body is enhanced greatly. The diversion device is wide in application and can be widely applied in underwater measuring of seas or lakes.

Description

technical field [0001] The invention belongs to the technical field of marine towed detection or towed bodies, and in particular relates to a flow guide device for enhancing the attitude stability of an underwater towed body. Background technique [0002] The marine towing detection method in the prior art generally uses the detection ship to tow the towing body or the towing body to move under the water surface, and at the same time use the detection equipment on the towing body or the towing body to detect the seabed environmental parameters such as terrain, landform, and hydrological parameters. etc. During the working process, the towing body is not only affected by the dragging speed of the detection ship, but also by the ocean current speed or surge, which makes its underwater posture not stable enough and prone to flipping or rolling. It affects the stability and detection accuracy of the detection. Therefore, it is necessary to develop a diversion device to locally s...
