Control system for blue-green algae fishing robot and control method thereof

Abstract

The invention discloses a control system for a blue-green algae salvage robot and a control method thereof, and belongs to the technical field of blue-green algae salvage. When the robot works in the cleaning area, a blue-green algae mixture enters the robot through the feeding port to complete the collecting action, in order to improve the cleaning efficiency of the robot, when the blue-green algae mixture is collected, the air exhaust mechanism is started to assist in collecting the blue-green algae mixture, and the blue-green algae mixture flowing into the robot flows inwards through the flow inlet channel; a plurality of permeation holes are formed in the tail part of the inflow channel, water in the blue-green algae mixture flows into the drainage area through the permeation holes, and the blue-green algae solid enters the packaging box, so that simple dry-wet separation is realized; the opening and closing mechanism is installed in the shell, the rhizomes of the blue-green algae can be cut off, and the situation that clamping stagnation affects the follow-up blue-green algae collection action is prevented.

Description

technical field [0001] The invention belongs to the technical field of cyanobacteria salvage, in particular to a control system for a cyanobacteria salvage robot and a control method thereof. Background technique [0002] Cyanobacteria, also known as blue-green algae and cyanobacteria, are the most primitive and ancient algae. Due to the adaptation of cyanobacteria to high temperature, low light intensity and ultraviolet rays, inorganic carbon and nutrients can be taken in excessively, and factors such as low nitrogen and phosphorus ratio are conducive to the growth of cyanobacteria; After the death of cyanobacteria, the smell is unpleasant and the landscape is destroyed; the death and decomposition of cyanobacteria consume too much oxygen, resulting in the death of other organisms due to hypoxia; a large number of cyanobacteria accumulate and die in the local lake area, which will destroy the water quality of the water source, secrete toxins, and directly endanger biologica...

AI Technical Summary

Problems solved by technology

Due to the adaptation of cyanobacteria to high temperature, low light intensity and ultraviolet rays, excessive intake of inorganic carbon and nutrients, low nitrogen to phosphorus ratio and other factors are conducive to the growth of cyanobacteria; large-scale outbreaks of cyanobacteria will make it difficult for submerged plants to grow and grow in large quantities. After the death and corruption of cyanobacteria, the smell is unpleasant and destroys the landscape; the death of cyanobacteria decomposes and consumes too much oxygen, which leads to the death of other organisms from lack of oxygen; the accumulation and death of cyanobacteria in local lake areas will destroy the water quality of the water source, secrete toxins, and directly endanger the survival of organisms and human health.

[0003] The common cyanobacteria control methods are divided into chemical method, biological method and physical method; chemical method will cause secondary pollution and affect the water body at the same time, so it is expressly prohibited to use; biological method adopts the way of ecosystem, by raising more carnivorous Eat algae fish to eliminate cyanobacteria, but the growth cycle of fish is long and unstable, so the effect is not very obvious; at present, the most adopted method for cyanobacteria treatment is to use physical methods, placing salvage robots in the cyanobacteria growth area, and reclaiming cyanobacteria, unified deal with

[0004] After retrieval, the Chinese Patent Publication No. is CN111270660A, a cyanobacteria salvage robot, which discloses a cyanobacteria salvage robot, comprising a shell, one end of the shell is provided with a feeding nozzle, and the rear of the feeding nozzle is arranged in the housing and in turn. There are collection bins, dehydration bins and storage bins, and a counterweight adjustment bin is provided under the dehydration bins; a conveyor belt for transporting blue-green algae is installed through the collection bin, dehydration bin and storage bin in the shell, and the conveyor belt is divided into a collection area section, lifting section and dehydration section; the top of the shell is provided with a control box, which is provided with a control circuit and a battery pack for power supply to the control circuit; the bottom of the dehydration section is provided with a control circuit to control the dehydration of cyanobacteria. Dehydration mechanism, the output end of the dehydration mechanism is connected with an exhaust pipe, the end of the exhaust pipe extends below the water surface and is provided with an aeration head; the bottom of the storage bin is provided with a discharge port, and the bottom of the shell is provided with a walking drive Mechanism, the present invention relates to the technical field of cyanobacteria salvage, although this reference document can automatically collect water bloom cyanobacteria, and crush, dehydrate, and recover and reuse cyanobacteria, which improves the removal efficiency of cyanobacteria; but this robot is continuous In the process of collecting cyanobacteria, if there are cyanobacteria with long roots, such cyanobacteria cannot be sent to the inside of the robot for crushing in time, and half of the cyanobacteria will be stuck inside the robot and the other half outside the robot, which will affect the follow-up. Collection work, therefore, how to prevent half of the cyanobacteria from being stuck inside the robot and the other half outside the robot is a problem to be solved at present
