Anti-wind and wave acoustic fish detection levitation device and fish detection array composed of the levitation device

Abstract

The invention discloses an anti-wave acoustic fish-finding suspension device and a fish finding array composed of the suspension device. The suspension device comprises a floating ring frame and a probing rod perpendicular to the plane where the floating ring frame is located, the probing rod is arranged in the circle center of the floating ring frame in a penetrated mode, the bottom and the top of the probing rod are located at the two sides of the plane where the floating ring frame is located respectively; a coil spring box is arranged at the bottom of the probing rod, and a soar which is vertical downwards is hung on the coil spring box through a hanging line; a control box and a navigation light are arranged at the top of the probing rod, the control box is internally provided with a controller, a battery and a wireless signal transmitter which are electrically connected with one another, and the sonar and the navigation light are electrically connected with the controller.

Description

technical field [0001] The invention relates to a fish-finding device, in particular to a wind-wave-resistant acoustic fish-finding levitator and a fish-finding array composed of the levitator. Background technique [0002] At present, there are many fish finder products on the market, and their working principle is realized through the principle of sound wave transmission by using sonar positioning technology. After the fish finder emits sound waves, it measures the distance by the time it takes for the sound waves to touch the object and return. Through the reflected sound wave signal, the fish finder can identify the information of the fish. [0003] A common fish finder consists of a probe with a sonar generator placed in the water when in use. The probe is placed on the water, the sonar signal is collected, and then the fish information is obtained through microprocessor calculation and displayed to the user. But usually the sonar is suspended into the water by buoys,...

AI Technical Summary

Problems solved by technology

But usually the sonar is suspended into the water through the action of buoys, etc. Under the action of wind and waves, the buoys will move greatly with the wind and waves, and will drive the sonar to move greatly underwater, which will affect the stability of sonar work, especially in wind and waves. under greater weather conditions
