Embodiment Construction

[0018] The present invention is further described below in conjunction with embodiment.

[0019] Such as figure 1 As shown, the present invention includes a fixed frame 1, a truncated cone bracket, an elastic cord 5, a fishing line 8, and a calibration ball 4. Fixed mount 1, truncated cone support are all stainless steel. The frustum-shaped bracket includes a rigid connecting steel column 6 and three steel rings 3 with different diameters. The steel rings 3 are fixed in parallel in order from large to small. The fixing method is to connect four equal parts of each steel ring 3 with four connecting steel columns 6 in sequence. In the distribution position, the four connecting steel columns 6 on the steel ring 3 with the smallest diameter extend vertically upward for a section for fixing and connecting the fixing frame 1 . A mounting hole matching the connecting rod of the acoustic probe is provided in the middle of the fixing frame 1 for fixing the acoustic probe 7 . In the ...

Abstract

The invention discloses a portable auxiliary calibration device for fishery acoustic equipment and a calibration method thereof. For fixing the acoustic probe, one end of each elastic rope is connected to equally spaced parts around the bottom of the frustum-shaped support, and the other end is converged to connect the calibration ball, and the calibration ball is fixed at the center of the bottom of the frustum-shaped support; each fishing line One end of one end is also converging to connect the calibration balls, and the other ends are respectively extended to the top of the fixing frame along the equally spaced distribution parts on the truncated cone-shaped bracket; the calibration device uses a bracket with a certain weight to fix the acoustic probe and the calibration balls, which can reduce the water flow. The impact on the equipment; the calibration ball is fixed on the bracket with an elastic rope, and the calibration ball can be automatically reset under the action of the elastic force.

Description

technical field [0001] The invention relates to a portable fishery acoustic equipment auxiliary calibration device and a calibration method thereof. Background technique [0002] Each fishery acoustic equipment must be calibrated in the field environment in a certain period in order to obtain more accurate target data (TS, SV, etc.). The quality of equipment calibration depends on the orientation and depth of the fixed-diameter calibration sphere in the body of water. In the ocean current environment, affected by factors such as ocean currents and surges, it is difficult to achieve accurate control. In this case, it can only be controlled in real time according to the environment, which will consume a lot of manpower and time, and the efficiency is very low. Therefore, how to complete the calibration of equipment in complex marine environments efficiently and with high quality has become an urgent problem to be solved in the application of fishery acoustic equipment. Cont...
