Problems solved by technology

However, the length of the towline deployed in some special occasions is limited, the second method is not applicable
For example, when the sea surveillance ship monitors the opponent's detection ship, the cable laid is too long, which will affect the maneuverability of the ship and bring difficulties to rights protection and law enforcement

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0039] As shown in Figures 1 to 6, the counterweight device used in the towed linear array of the present invention consists of a first semi-cylindrical counterweight 1, a second semi-cylindrical counterweight 2, an attached protective cover 3, a buckle 41. The lock block 42, the snap ring 43, the second hinge 44, the third hinge 45, the first hinge 5, the adjustment block 6 and the adjustment screw 7 are composed. The lock block 42 is combined with the third hinge 45 and installed on the hasp 41, and the lock block 42 should rotate flexibly on the hasp 41; the combination of the hasp 41 and the second hinge 44 is installed on the first half cylinder counterweight , the hasp 41 should rotate flexibly on the first half cylinder counterweight; the first half cylinder counterweight 1, the second half cylinder counterweight 2 and the first hinge 5 a...

Abstract

The present invention provides a counterweight device for a towed line array and a towed line array, comprising: a first semi-cylindrical counterweight and a second semi-cylindrical counterweight with a semi-circular section, Buckle type locking mechanism, first hinge; a contact surface of the first semi-cylindrical counterweight and the second semi-cylindrical counterweight is connected through the first hinge, when the first semi-cylindrical counterweight When the opening angle of the counterweight and the second semi-cylindrical counterweight is zero, the two counterweights cooperate with each other to form a hollow cylinder. When the first semi-cylindrical counterweight and the second semi-cylindrical counterweight are opened into It is used to place the towing cable to the hollow part of the above-mentioned cylinder when the angle is at an angle; A streamer placed closely on the hollow part; wherein, the cylinder ends of the first semi-cylindrical counterweight and the second semi-cylindrical counterweight are also provided with a first conical guide section.

Description

technical field [0001] The invention relates to a counterweight structure applied to a towed line array, and relates to a counterweight device suitable for a towed line array. Background technique [0002] The towed line array is a main acoustic detection equipment, widely used in oil exploration and target detection and other fields. The detection performance of the line array is affected by factors such as the ocean environment and the propagation characteristics of underwater sound in the ocean, among which the influence of the propagation characteristics of underwater sound is particularly prominent. For the same set of towed line arrays, different detection results will be obtained because the users have different understandings of the acoustic propagation characteristics. Therefore, users need to reasonably select the deployment depth of the acoustic module section in the line array according to the sound velocity profile in the hydrological information during use, so...
