Lifting type water-based blue-green algae fishing device

Abstract

The invention relates to a blue-green algae fishing device, in particular to a lifting type water-based blue-green algae fishing device. The lifting type water-based blue-green algae fishing device comprises a work platform and fixing piles, and algae fishers are arranged on the work platform. The number of the fixing piles is four, and the four fixing piles are all vertically arranged and located at the four corners of a rectangle. The lifting type water-based blue-green algae fishing device is characterized in that the upper ends of the fixing piles are concentrically connected with guide piles correspondingly, the work platform is located on the inner sides of the guide piles, buoys are fixed to the two sides of the lower portion of the work platform correspondingly, and the two horizontal ends of each buoy are matched with the corresponding guide piles in a vertically sliding mode. The blue-green algae fishing device can rise and fall automatically along with rising and falling of the water level and is prevented from being submersed in the flood seasons, and it can be ensured that blue-green alga are fished smoothly.

Description

technical field [0001] The invention relates to a blue-green algae fishing device, in particular to a water-liftable blue-green algae fishing device with self-adaptive lifting function. Background technique [0002] In recent years, cyanobacterial blooms have become a major water environmental problem in lakes, reservoirs, and fish ponds in China. Water pollution caused by cyanobacterial blooms has had a serious impact on human life and the ecological environment. In addition, cyanotoxins can seriously endanger human health. This kind of harm has become more and more serious, especially in summer and autumn, when blue-green algae multiply and form a layer of blue-green and fishy-smelling foam on the water surface, which seriously consumes oxygen in the water, causing a sharp drop in water quality. Occurrence of fish kills, etc. [0003] In the prior art, the main ways to salvage and collect cyanobacteria floating on the water surface are: manual salvage, or extracting cyan...

AI Technical Summary

Problems solved by technology

However, both approaches have many drawbacks

Manual salvage has problems such as low salvage efficiency and high manpower and material costs

The algae suction method of extracting cyanobacteria from the water surface through a fixed salvage platform combined with a water pump has the following defects: ①The height of the fixed salvage platform is limited. The water level exceeds the limit of the fixed salvage platform, which often causes the platform to be submerged in water. At this time, the cyanobacteria salvage work cannot be carried out; ② Most of the existing fixed salvage platforms are set It belongs to seasonal work, and the salvage equipment is idle and unattended in autumn and winter, which not only greatly affects the surrounding ecological landscape, but is also vulnerable to man-made damage, theft and natural aging.
