A deep-water multi-purpose portable visual fish finder

Abstract

The invention provides a deep-water multi-purpose portable visual fish finder, which relates to the technical field of visual fish finder. A counterweight tank is embedded in the groove, and the counterweight tank is filled with counterweight liquid. A monitor is installed at the center of the front end of the base. The monitor is used to photograph fish, and a nozzle is installed at the bottom of the counterweight tank. , the inside of the nozzle is equipped with a solenoid valve, which solves the problem of the existing limitation that if the power of the device is low during the observation operation, the automatic ejection of the water surface cannot be performed, and then there is a limitation. The valve will automatically be in the open state to spray out the counterweight liquid injected into the counterweight tank, and accelerate the upward movement of the base through the injection of the counterweight tank, and assist the device to move upwards by reducing the weight after the counterweight tank is released. operate.

Description

technical field [0001] The invention relates to the technical field of visual fish finder, in particular to a deep-water multi-purpose portable visual fish finder. Background technique [0002] The visual fish finder, as the name suggests, has a video device on the fishing rod, that is, a visual fishing system, such as a mobile phone-like screen, to achieve a visual fishing rod, generally referred to as a fish finder, which can observe the terrain, fish schools, etc. [0003] For example: Application No. CN202210047015.8, the present invention proposes a fish-passing monitoring device, which includes a fish-passing channel, an infrared backlight, a reflector and an image acquisition device, and the infrared backlight and the reflector are arranged facing each other along the level of the fish-passing channel. On the inner walls of the opposite sides, the image acquisition device is fixedly installed on the outside of the fish passage and above the fish passage. The infrared ...

Problems solved by technology

[0004] However, as far as the current fish finder is concerned, it often needs to be photographed by a camera when exploring fish schools at the bottom of the water, and the photographing of the camera will cause the camera to appear due to the entanglement of aquatic plants or the collision of sharp stones on the bottom side of the water surface. damage, which in turn will affect the normal observation of fish schools, and if the power of the device is low during observation operations, it will not be able to perform automatic pop-up work, which in turn has limitations
