Water surface dead fish salvaging device for fish unloading wharf

Abstract

The invention discloses a water surface dead fish salvaging device for a fish unloading wharf. The water surface dead fish salvaging device comprises a box. An L-shaped connection plate is arranged onthe right side of the top of the box, and a buffer spring is arranged on one side of the bottom of the connection plate. A fixed plate is arranged at the bottom of the buffer spring. Two first extending plates and two second extending plates are arranged at the top and in the middle of the left side inner wall of the box correspondingly and are all arranged obliquely. Two distribution rods are arranged in the middle of the left side inner wall of the box. Appropriate water flow striking angles to a first blade and a second blade are ensured, gravitational potential energy of water flow is fully utilized, insufficient rotation of the blades due to large-area falling of the water flow is avoided, salvaging efficiency of dead fish is improved, discharged water can wash the interior of a groove while lubrication is conducted between the dead fish and the groove, and blocking is effectively prevented when the dead fish is collected.

Description

technical field [0001] The invention relates to the technical field of fish unloading wharf, in particular to a fishing device for dead fish on the water surface of the fish unloading wharf. Background technique [0002] Fish unloading wharf is a wharf specially used for fishing vessels to unload fishery goods. It usually has facilities such as lifting fishery goods and conveyor belts. There should be corresponding conditions for handling and processing, refrigeration and transportation of fishery goods on land. There are some dead fish falling on the water surface during delivery. The dead fish floating on the water surface not only cause water surface pollution, but also cause waste. At present, it is manually salvaged with fishing nets, which is time-consuming and laborious, and the operation is dangerous. [0003] After searching, the Chinese patent application number is CN108532571A, which discloses a garbage salvage device, including a support frame, a first handle is ...

AI Technical Summary

Problems solved by technology

The garbage salvage device in the above patent has the following disadvantages: 1. The kinetic energy of the water flow cannot be fully utilized to convert it into electric energy, which is not energy-saving and environmentally friendly; 2. The salvage range is small, and it is difficult to salvage the water surface garbage around the salvage device, and the salvage efficiency is low
