Embodiment Construction

[0027] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0028] according to figure 1 , figure 2 The device shown as a side-mounted wireless network hydrophone includes a hydrophone cover 1, a steel rod 2, a steel rod hoop 3, a hull fixed base 5 fixed above the ship's waterline L2, and a fixed base-steel The connecting piece between the rods 4.

[0029] The hydrophone cover 1 is used to install the hydrophone, and plays a role of protection and diversion. The steel rod 2 is divided into two steel rod sections, the hydrophone cover 1 is welded to the bottom end of the first steel rod section, the first steel rod section passes through the steel rod hoop 3 and the second steel rod section Connect and fix the angle. The steel rod hoop 3 is fixed by screws and nuts, and a screw pin is used to prevent the two steel rod sections from rotating, misaligning, or sliding off. According to the depth of the ship, multiple st...

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 a hull fitting, in particular to a device for installing a hydrophone. Background technique [0002] The wireless trawl monitoring system can provide a wealth of information about the gear, including: 1. The depth and height of the fishing net, the expansion between the upper and lower ones, the angle, the water temperature, and the distance between the lower and the bottom of the net; 2. Depth, angle, distance information between the main and auxiliary (horizontal expansion), water temperature, the distance between the net plate and the ship; 3. The depth and angle of the left and right net wings, the horizontal expansion of the net wings, the water temperature, and the distance between the net wings and the ship; 4. , Whether the catch in the net bag is full; 5. The angle of the selective device, the vertical and horizontal speed of the fishing net against the water; 7. Early warning of obstacles that may cause the net to break; 8...
