Nori net curtain fixed green alga removing device

Abstract

The invention discloses a nori net curtain fixed green alga removing device. The nori net curtain fixed green alga removing device comprises a removing assembly, a cleaning assembly, a first liquid supply assembly and a second liquid supply assembly; the removing assembly and the cleaning assembly are sequentially arranged in the moving direction of a net curtain; the removing assembly comprises a first box body, a first guide roller, a second guide roller, a flushing part and a friction part; the first guide roller, the second guide roller, the flushing part and the friction part are arranged in the first box body; the first guide roller is rotationally arranged on the lower portion of the first box body, and the second guide roller is parallel to the first guide roller and rotationally arranged on the upper portion of the first box body; the flushing part is arranged between the first guide roller and the second guide roller; and the friction part is arranged at the bottom of the first box body and located below the first guide roller. The nori net curtain green alga removing device can rapidly and efficiently remove nori net curtain green alga in a labor-saving mode, manpower, material resources and time are greatly saved, and protection of the offshore area environment is facilitated.

Description

technical field [0001] The invention relates to the field of marine biology research, in particular to a device for removing fixed green algae from laver net curtains. Background technique [0002] The Yellow Sea green tide has broken out year after year since 2008, causing serious impacts on the coastal environments of Jiangsu and Shandong. Research at home and abroad has found that the green tide in the Yellow Sea originated from the net curtain of laver cultivation in Jiangsu. Under the action of the monsoon, the green algae falling from the seaweed cultivation net floated from Jiangsu to the Shandong Peninsula to form a large-scale green tide. Prevention and control of green tide from the source, that is, clearing the fixed green algae on the net curtain of laver cultivation, can achieve twice the result with half the effort for the prevention and control of green tide. At present, the removal of fixed green algae on the net curtain of seaweed cultivation generally ado...

AI Technical Summary

Problems solved by technology

At present, the removal of fixed green algae on the net curtain of seaweed cultivation generally adopts the method of artificially applying biological acid and then flushing with water pipes. This method not only consumes a lot of manpower, material resources and time, but also has poor removal effect. How can it be more efficient and labor-saving? It is a technical problem to be urgently solved in this field to realize the removal of the fixed green algae of the laver net curtain and to better realize the protection of the coastal sea area environment.
