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 invention provides a counterweight device for a towing-type linear array and the towing-type linear array. The counterweight device for the towing-type linear array comprises a first semi-cylinder counterweight block, a second semi-cylinder counterweight block, a buckle-type locking mechanism and a first hinge, wherein the section of each counterweight block is of a semi-circular ring shape; one contact surface of the first semi-cylinder counterweight block is connected with one contact surface of the second semi-cylinder counterweight block through the first hinge; when the opening angle of the first semi-cylinder counterweight block and the second semi-cylinder counterweight block is zero, the two counterweight blocks are matched with each other to form a hollow cylinder; when the first semi-cylinder counterweight block and the second semi-cylinder counterweight block are opened at a certain angle, a towing cable is placed in a hollow part of the cylinder; the buckle-type locking mechanism is used for clamping the first semi-cylinder counterweight block and the second semi-cylinder counterweight block on the towing cable placed in the hollow part when the opening angle is zero; a first conical flow guide section is further arranged at the end part of the cylinder formed by the first semi-cylinder counterweight block and the second semi-cylinder counterweight block.

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...
