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...
