Problems solved by technology

[0002] At present, the number of offshore streamers used in seismic exploration is also increasing, and the distance between them is getting smaller and smaller, so the requirements for their shape are becoming more and more strict. Various reasons such as the difference in cable geometry will make it bend, which may cause entanglement between two adjacent tow cables, or collide with each other and damage the equipment inside, so it is necessary to control the horizontal position of the tow cables

Embodiment Construction

[0022] The present invention belongs to the plug-in device, referring to Fig. 1 . Figure 1 shows the specific installation position of the marine towed linear array three-wing balanced deployment device of the present invention on the tow cable, wherein 1 is the tow cable, 2 is the installation ring connected with the tow cable, and 3 is the deployment device of the present invention. Since the device is an external device (as shown in Figure 1), it will inevitably generate fluid noise when towing, so the device adopts a streamlined design to reduce the fluid noise generated in the seismic frequency band.

[0023] Fig. 2 is a balance principle diagram of the marine towed linear array three-wing balanced deployment device of the present invention. During the working process of the deployment device, the two balance wings are differentially adjusted, that is, the angles of attack of the two wings are equal in size and opposite in direction. Therefore, the torques M1 and M2 in th...

Abstract

This invention discloses one sea towing wire array three-blade balance extension device, which comprises pressure enduring shell, execution structure, communication and control device, measurement device and blade board, wherein, the blade board is fixed on the relative part of the shell through shaft and executes is of one or two sets and comprises orderly execution motor, decelerator, clutch, feed screw and line and rotation conversion device; the blade board is composed of vertical extension blade and two level balance blade boards as angle size and reverse direction.

Description

technical field [0001] The invention belongs to a transverse horizontal control towed linear array deployment device and method mainly used for marine towed cables for marine seismic exploration. Background technique [0002] At present, the number of offshore streamers used in seismic exploration is also increasing, and the distance between them is getting smaller and smaller, so the requirements for their shape are becoming more and more strict. Various reasons such as the difference in cable geometry will make it bend, which may cause entanglement between two adjacent tow cables, or collide with each other and damage the equipment inside, so it is necessary to control the horizontal position of the tow cables . Contents of the invention [0003] The purpose of the present invention is to provide a marine towed linear array three-wing balance deployment device and a method for determining the zero angle of attack of the wing plate, so as to solve the problem of automati...
