A front-extended trawling device for fishing boats based on surface fishing

Abstract

The invention discloses a fishing boat front extension type trawling device based on water surface fishing, which belongs to the technical field of marine equipment. It includes a telescopic positioning structure, a net opening support structure, a fishing net body, a fishing landing structure, a lifting segment structure and a lifting sealing structure; the device can drive the telescopic positioning structure to establish a fishing net body in front of the hull structure through a telescopic driving structure, and The inlet end of the fishing net body is maintained at a predetermined distance in front of the hull structure by means of the net port support structure, so that fish schools located in the top waters enter the fishing net body from the inlet end; the lifting and lowering movement of the fishing lifting structure can be driven synchronously Segmented structure and lifting sealing structure, through the lifting segmented structure, the fish gathered at the tail end of the fishing net body can be lifted up separately, and the outlet channel can be formed at the tail end of the fishing net body through the lifting sealing structure and further drive the outlet The channel rises so that the fish can fall into specific containers in the hull structure by their own gravity.

Description

Technical field [0001] The present invention relates to the field of marine equipment, and more particularly to a fishing vessel preamplifier trawler based on a surface-catching fishing. Background technique [0002] At present, with the continuous improvement of fishing technology, mechanized ocean fishing boats have become one of the main ways of fishing boats. Among them, trawling fishing is widely used, and is the most mainstream fishing method because of the convenient operation. In the prior art, trawl fishing is dragging the rear fishing net through a fishing vessel, and the fishing nets go in with the hull, "pocket", "pocket", and then collect the net. [0003] However, since the fish in the hull is usually driven by the hull of the top waters, it will disperse the fish in the two sides, which will result in a subsequent trails that cannot be effectively caught. Therefore, the goal of the existing fishing trawl is mainly against shrimp crabs, fish, fish and mid-waters fis...

Problems solved by technology

[0004] For this reason, the present invention provides a fishing boat front extension type trawling device based on water surface fishing, to solve the problem that the fishing trawl in the prior art cannot meet the fishing demand for fish schools in the top waters, resulting in relatively high limitations in the use of the trawl , technical problems with low functional practicability
