Abstract

The invention belongs to the technical field of blue algae treatment, and particularly relates to an urban park lake blue algae fishing device and an operation method. The urban park lake blue algae fishing device comprises a collecting roller, wherein a plurality of telescopic grooves are formed in the annular side of the collecting roller; a filter screen is arranged inside the telescopic grooves; telescopic rods are fixedly connected to the two ends of the filter screen; guide blocks are fixedly connected to the ends, far away from the collecting roller, of the telescopic rods; a pluralityof balls are arranged on the outer sides of the guide blocks; a guide curve plate is arranged on the side surface of the collecting roller; a shaft rod is arranged in the middle of the collecting roller; supporting blocks are arranged at the two ends of the shaft rod; the two sides of the guide curve plate are fixedly connected with the supporting blocks; the shaft rod penetrates through the rightends of the supporting blocks and is provided with a motor; floating blocks are arranged on the lower sides of the supporting blocks; pull ropes are arranged on the lower sides of the floating blocks; and balancing weights are fixedly connected to the lower ends of the pull ropes. The urban park lake blue algae fishing device is small in size, suitable for being operated in an urban park lake andhigh in fishing speed.

Description

technical field [0001] The invention belongs to the technical field of water conservancy facilities, and in particular relates to an urban park lake cyanobacteria salvage equipment and an operation method. Background technique [0002] Cyanobacteria blooms can cause deterioration of water quality, and in severe cases deplete the oxygen in the water and cause the death of fish. At the same time, a large number of cyanobacteria accumulate on the surface of the water body, which not only affects the water body landscape, but also if such a water body is used as a drinking water source, the large amount of cyanobacteria accumulated will bring serious harm to the safety of tap water treatment and water sources. One of the important reasons why cyanobacterial blooms have received widespread attention is because cyanobacteria can produce a variety of natural toxins that can potentially inhibit their competitors (other phytoplankton and higher aquatic plants) and predators (fish, zo...
