Device for side-mounting wireless trawl hydrophones

Abstract

The invention relates to a device for side installation of a wireless trawling hydrophone. The device comprises a hydrophone cover, and also includes a steel rod, the hydrophone cover is fixed at the bottom of the steel rod, the steel rod is equipped with at least two ship body fixed bases, and the fixed bases are fixedly connected to the steel rod through a connecting piece. According to the invention, an underway ship has no need for docking during installation of a wireless trawling monitoring system hydrophone (underwater part), and the angle of the hydrophone can be adjusted randomly to meet good communication with a sensor on a net. For a rentable test ship, the installation is very simple before test, and disassembly is also convenient and fast at the end. Hydrophone maintenance is also very convenient. Therefore, the efficiency of installation, disassembly and maintenance is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to ship hull accessories, in particular to a device for installing hydrophones. Background technique [0002] The wireless trawl monitoring system can provide a wealth of information on nets, including: 1. The depth and height of the fishing net, the expansion between the upper and lower nets, the angle, the water temperature, and the distance from the lower net to the seabed; 2. The main and auxiliary net plates Depth, angle, distance information between main and auxiliary (horizontal expansion), water temperature, the distance from the screen to the ship; 3. The depth, angle of the left and right screen wings, horizontal expansion of the screen wings, water temperature, and the distance from the screen wing to the ship; 4 . Whether the net bag is full of fish; 5. The angle of the selective device, the longitudinal and lateral speed of the fishing net to the water; 7. Early warning for obstacles that may cause the net to break; 8...

AI Technical Summary

Problems solved by technology

This brings a lot of inconvenience to ship owners and scientific research units, generates a lot of cost, and wastes a lot of time

[0005] Moreover, after the hydrophone is fixed in this way and the ship is launched into the water, once there is a problem with the installation angle of the hydrophone or the instrument is damaged, the ship must be re-docked for adjustment, repair, replacement, or disassembly.
