Deepwater multipurpose portable visual fish finder

Abstract

The invention provides a deepwater multipurpose portable visual fish finder, and relates to the technical field of visual fish finders, the deepwater multipurpose portable visual fish finder comprises a base, arc-shaped grooves are formed in the left and right sides of the base, counterweight tanks are embedded in the arc-shaped grooves formed in the base, counterweight liquid is injected into the counterweight tanks, and the counterweight liquid is filled with water. A monitor is installed in the center of the front end face of the base and used for shooting fish schools, a spraying pipe is installed at the bottom end of the balance weight tank, and an electromagnetic valve is installed in the spraying pipe, so that the problem that in the prior art, when observation operation is conducted, if the electric quantity of a device is low, the device cannot be automatically ejected out of the water surface for work, and then limitation exists is solved; when the electromagnetic valve installed in the spray pipe can be automatically in an open state to spray out the counterweight liquid injected into the counterweight tank, upward movement of the base is accelerated through spraying of the counterweight tank, and the device is assisted in upward movement operation through weight reduction after the counterweight tank is released.

Description

technical field [0001] The invention relates to the technical field of visual fish finders, in particular to a deep-water multipurpose portable visual fish finder. Background technique [0002] Visual fish finder, as the name suggests, has a video device on the fishing rod, that is, a visual fishing system. The screen like a mobile phone can reach a visual fishing rod. Generally speaking, it is called a fish finder, which can observe terrain, fish schools, etc. [0003] For example: application number CN202210047015.8, the present invention proposes a fish-passing monitoring device, including a fish-passing channel, an infrared backlight panel, a reflector and an image acquisition device. On the inner walls on both sides opposite to each other, the image acquisition device is fixedly installed on the outside of the fish passage and above the fish passage. The infrared backlight emits infrared light and passes through the inner passage of the fish passage and projects it onto...

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
