Collecting device for coral reef area spinous crown starfish

Abstract

The invention provides a coral reef area spinous-crown starfish collecting device, belongs to the technical field of marine ecological environment treatment, and solves the problems that spinous-crown starfishes are difficult to effectively and quickly collect, capture and convey and the like. Comprising a collecting ship, the upper end of the collecting ship is provided with a placing bin, a lifting hydraulic column and an angle adjusting conveying mechanism, the upper end of the lifting hydraulic column is provided with a main supporting frame, the lower end of the main supporting frame is provided with a rotating mechanism, the lower end of the rotating mechanism is provided with a telescopic conveying mechanism, and the front side of the rotating mechanism is fixedly provided with a connecting frame; a medicine injection mechanism and an adjusting mechanical arm are arranged at the lower end of the telescopic arm mechanism, a clamping jaw mechanism is arranged at the end of the adjusting mechanical arm, and a containing cloth bag is arranged on the rear side of the lower end of the rotating mechanism. The device can quickly clamp, collect, capture and convey the spinous crown starfish, quantitatively inject medicine to the spinous crown starfish, quickly kill the spinous crown starfish, and facilitate later collection; and the method also can introduce the lava into the coral area for biological control, and is good in effect and low in cost.

Description

technical field [0001] The invention belongs to the technical field of marine ecological environment management and relates to a collection device for crown-of-thorns starfish in coral reef areas. Background technique [0002] Coral polyps are automatically fixed on the calcareous remains of ancestor corals at the white larval stage. Corals are the shells secreted by coral polyps. The chemical composition of corals is mainly calcium carbonate, which exists in the form of microcrystalline calcite aggregates. The organic matter is mostly in the form of dendrites, with vertical stripes on it. The cross-section of each individual coral has concentric circles and radial stripes. The color is often white, and there are also a small amount of blue and black. Coral not only looks like branches, but also has bright and beautiful colors. , can be used as decorations, and has high medicinal value, but its role in the environment is irreplaceable compared to the medicinal value.

AI Technical Summary

Problems solved by technology

[0005]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 diving into the seabed by divers. The removal of starfish attached to coral reefs is inefficient and poses a great safety hazard; underwater robot injection refers to the use of agents that can kill starfish to inject into starfish, and quickly kill starfish to achieve the purpose of removing starfish from coral reefs , but deadly starfish decay in the coral reef ecosystem, which may cause secondary pollution. There are still new threats to the coral reef ecosystem, and there is a lack of secondary collection; using bait to catch starfish is to use the bait that starfish likes to attract starfish to leave the coral reef area , this method is safe, but it may attract other marine life, and after the bait disappears, the starfish will still return to the coral reef, and the removal is not complete

[0006]Mature crown-of-thorns starfish have almost no natural enemies, except for the snails, so the snails are used for biological control. After the snails capture the snails, they will use them as The rasp-like tongue tears the starfish into tiny pieces and swallows them into the stomach, making it impossible for the crown-of-thorns starfish to regenerate
