A device for catching sea stars on coral reefs

Abstract

The invention discloses a device for catching starfish on coral reefs, which includes a hull, a grasping system and an injection system arranged on the hull; the injection system includes an injection robot arm installed on the hull, and an injection robot attached to the coral reef The syringe for injecting medicaments for starfish; the grasping system includes a lifting arm installed on the hull, and a grasping mechanical arm hoisted into the sea surface by the lifting arm, and the moving end of the grasping mechanical arm is set There is a mechanical gripper for grabbing and catching starfish after injecting medicine. The invention is a starfish detoxification device with high capture efficiency and environmental friendliness to coral reefs, and has remarkable technical effects on restoring the ecological environment of coral reefs by controlling starfish on coral reefs.

Description

technical field [0001] The invention belongs to marine ecological environment management technology, in particular to a device for catching sea stars on coral reefs. Background technique [0002] Coral reefs are one of the marine ecosystems with extremely high biological productivity and biodiversity. They have the highest biodiversity and productivity among all marine ecosystems. There are about 900,000 species of organisms. Although the area accounts for only 0.2% of the world's marine ecosystems, However, their value and the services they provide account for 2.85% of marine ecosystems, showing the global contribution of coral reefs. Hundreds of millions of people currently live near coral reefs. Coral reefs provide a source of food for local residents and a place for recreation and entertainment for divers. [0003] Due to typhoon weather, reduction of coral reef fish, global warming, human activities and other factors, starfish have experienced large-scale outbreaks in ...

AI Technical Summary

Problems solved by technology

[0004] At present, the methods to prevent and control starfish outbreaks mainly include manual removal and cleaning, underwater robot injection, and bait capture. Manual removal and cleaning refers to the removal of starfish attached to coral reefs by divers diving into the seabed. This method only It can effectively control short-lived and small-scale starfish outbreaks, but for large-scale and large-scale outbreaks, it seems to have more than enough power, and manual cleaning of starfish poses a greater safety hazard to divers on the seabed; underwater robot injection refers to the use of The agent that can kill starfish is injected into the starfish, and the purpose of removing starfish on coral reefs is achieved by quickly killing starfish. However, dead starfish rot in the coral reef ecosystem, which may cause secondary pollution, and there are still new threats to the coral reef ecosystem. ;Using bait to catch starfish is to use the bait that starfish likes to attract starfish to leave the coral reef area. Although this method is safe, it may attract other marine life, and after the bait disappears, the starfish will still return to the coral reef. thorough
