Novel nearshore enteromorpha collecting device

Abstract

The invention discloses a novel nearshore enteromorpha collecting device. An acquisition and transmission device is arranged in a manner of tilting upwards, the top end of the acquisition and transmission device is mounted at the front end of a boat body through a support shaft, and a hydraulic cylinder is mounted between the acquisition and transmission device and the boat body. A gathering device comprises two baffles, the two baffles are separately connected to the two sides of the bottom end of the acquisition and transmission device through connecting shafts, and the gathering angle and range are changed through the telescoping of the hydraulic cylinder. A negative pressure absorption device is arranged at the middle lower part of the acquisition and transmission device. The negative pressure absorption device comprises a propeller and an adjusting device, and the propeller is fixed to the water surface bellow a conveyor belt of the acquisition and transmission device. A shredding device is mounted above the top end of the acquisition and transmission device through a base, and the shredding device consists of a feeding opening, a shredding cavity, a discharging opening and a blade. The fishing device combines collection, fishing and shredding. By adopting the negative pressure absorption principle, enteromorpha is enabled to float onto the conveyor belt, so that the fishing efficiency is increased, and the secondary pollution of the enteromorpha to shores is avoided.

Description

technical field [0001] The invention belongs to the technical field of marine algae cleaning equipment, and in particular relates to a novel coastal enteromorpha collection device. Background technique [0002] Enteromorpha grows in clusters near the sea in summer, with obvious main branches and slender branches, up to 1 meter high. Due to global climate change, water eutrophication and other reasons, China's coastal intertidal zone has grown, and the East China Sea coast has the largest production, resulting in the outbreak of green tides of large marine algae Enteromorpha. A large amount of Enteromorpha floats and gathers on the shore, blocking waterways, destroying marine ecosystems, and seriously threatening the development of coastal fisheries and tourism. [0003] Enteromorpha is rich in carbohydrates, protein, crude fiber and minerals, as well as fat and vitamins. Enteromorpha is the raw material of natural ideal nutritional food with high protein, high dietary fibe...

Problems solved by technology

Using low-power fishing boats to fish manually with hand-made nets is slow, inefficient, labor-intensive, and the effect is very inconspicuous. In 2014, several Enteromorpha fishing boats equipped with double-wing attack nets around the offshore loading and unloading platform had a greater salvage effect. improve

However, ordinary fishing boats are used for salvage at sea, and the speed of ordinary fishing boats is low. From salvage at sea to returning to the base, it can only be salvaged once a day, and the amount of fresh enteromorpha per boat is small, and the efficiency is low, which cannot meet large-scale enteromorpha cleaning. According to the needs of disposal work, the salvaged Enteromorpha moss is generally piled up on the shore, causing secondary pollution to the coast. At the same time, the near-shore sea area is relatively shallow, and the shape of the shore is complicated, which is not suitable for fishing boats.
