Fish-finding device capable of realizing panoramic photographing

Abstract

The invention belongs to the technical field of underwater detection, and discloses a fish-finding device capable of realizing panoramic photographing. The fish-finding device comprises a detector body, a first propeller and a second propeller are fixed to the left side edge and the right side edge of the detector body, a left motor and a right motor are fixed into the detector body through boltsand connected with the first propeller and the second propeller through transmission shafts, one end of the detector body is fixedly connected with a sonar detector through bolts, a second hinge support is fixed at the other end of the detector body through bolts and connected with a first hinge support through screws, and the first hinge support is connected with a camera in a sleeving manner andfixed by bolts. Image acquisition definition is improved by combination of the sonar detector and the camera. By the aid of the first propeller and the second propeller, the shooting position and thedirection of the fish-finding device can be changed, fish schools can be more comprehensively detected, and more intuitive and more accurate fish school data are acquired.

Description

technical field [0001] The invention belongs to the technical field of underwater detection, and in particular relates to a fish detection device capable of panoramic photography. Background technique [0002] The fish detection device is positioned by sonar. Based on the principle of sound wave propagation, the sound wave signal is reflected through water and air, and the signal reflected from the contact object in the water is used by ultrasonic waves. The signal is then processed by the internal processor and finally displayed on the screen, so that the water can be detected. The outline, composition, and bottom conditions of the fish below. [0003] At present, in the cold winter, due to the low temperature, low oxygen content in the water, and low activity of fish at the bottom of the water, fishing enthusiasts on the shore cannot understand the distribution of the bottom fish layer, making it difficult for fishing enthusiasts to catch fish. The fish comes, which great...

AI Technical Summary

Problems solved by technology

[0005] (1) During the use of traditional fish finders, the detection device cannot change its position and direction in the water, resulting in a narrowed detection range and no accurate fish data.

[0006] (2) Existing fish finders only carry batteries during use, so that fish cannot be detected when the power is exhausted, prolonging the detection time and reducing work efficiency
