Problems solved by technology

[0003] The main disadvantages of the existing positioning devices are: 1) In the existing plug-in devices, the depth control device is separated from the level control device, so the system will not only become very large and expensive, but also increase the fluid noise of the system ; 2) In the non-plug-in device, only the coupling control of the vertical position and the horizontal position can be realized, so when only the vertical or horizontal position of the tow cable needs to be changed, the position in the other direction will inevitably be affected; 3) Only by Battery pack power supply, short working life

Abstract

The invention belongs to the field of ocean monitoring technology, and particularly relates to ocean earthquake towed cable positioning devices and positioning methods. The invention discloses a ocean towed line array three-wing positioning device which combines a depth control device and a horizontal control device together, and comprises a posture sensor (2) arranged in a shell (1), a communication and control unit, a standby battery unit (4), a wing plate driving unit (6), a power supply unit (7), a pressure sensor (8), a communication coil (9), a vertical wing plate (5) arranged at the bottom of the shell, and two horizontal wing plates (10) arranged at two sides of the shell (1); and the positioning device is mainly characterized in that the principle that the wing plates generates lift force relative to water flow movement is utilized, the action force of the wing plates in horizontal direction and vertical direction is controlled by controlling attack angles of the wing plates,so as to further adjust the positions of a towed cable.

Description

technical field [0001] The invention belongs to the technical field of marine monitoring, in particular to a device and a positioning method for marine seismic towing and positioning. Background technique [0002] In order to improve the efficiency of marine seismic exploration and the accuracy of seismic data, the number of cables towed by seismic exploration ships is increasing, and the distance between adjacent cables is getting smaller and smaller. Therefore, the requirements for the control of formation parameters are increasing. The more stringent, the formation parameters mainly include cable depth, cable straightness, spacing between cables, and the degree of offset of cables relative to the track of the tugboat. When the ocean towing system is towing in the water, it will deviate from its expected depth and heading or be in a curved state due to various reasons such as its own negative buoyancy, ocean currents, and differences in the geometric shape of the towline. ...
