Special audio-frequency ultrasonic ricefield eel catching cage

Abstract

The invention relates to a special audio-frequency ultrasonic ricefield eel catching cage. A rectangular steel framework is wrapped by meshes, two ends of the steel framework wrapped by the meshes are provided with ricefield eel inlets respectively, and the ricefield eel inlets extend inwards to be connected with inner barbs; a ricefield eel storage bag is connected to the middle of the steel framework wrapped by the meshes; a waterproof box is arranged in an inner cavity of the steel framework wrapped by the meshes, a ricefield eel ultrasonic generator, a ricefield eel sonar generator, a ricefield eel frequency modulator and a ricefield eel audio-frequency sensor are mounted in an inner cavity of the waterproof box, a sound wave wire of the ricefield eel ultrasonic generator is connected with a sonar wire of the ricefield eel sonar generator, the sonar wire of the ricefield eel sonar generator is connected with a frequency modulation wire of the ricefield eel frequency modulator, and the frequency modulation wire of the ricefield eel frequency modulator is connected with a sensing wire of the ricefield eel audio-frequency sensor.

Description

technical field [0001] The invention relates to a cage specially used for catching eel, in particular to a cage specially used for catching rice eel with ultrasonic audio frequency, and belongs to the technical field of cages for eel catching of sonic waves. Background technique [0002] At present, when eels are caught by farming eels, they generally place bottom nets on a fixed water surface, put ricefield eel feed on the bottom nets, attract the eels to eat on the bottom nets, and then lift up the bottom nets to catch ricefield eels. Although this kind of capture is effective , but there are certain defects. First, it takes time and effort to place the bottom net. The eels that are not caught when the net is collected are easily frightened. The frightened eels dare not eat for two to three days, which affects their growth. The second is that the bottom net is easy to cause The eels bite each other and squeeze each other during the capture, and the eels that are too small ...

Problems solved by technology

[0005] Beneficial effects of the present invention: Since the present invention adopts the above scheme, soft and soft beards are respectively designed in the cage, the second fish storage bag is set, and the storage space is increased in the fish storage bag, with ultrasonic audio frequency After the cage is launched into the water, the ultrasonic device, sonar device, and frequency modulator installed in the cage can emit ultrasonic waves and audio through the sensor. In the cage, as long as the rice field eel enters the cage, it will be captured, and the purpose of the present invention is achieved. The cage of the present invention is durable, and the rice field eel is not frightened when caught, saving time and effort, no damage to the caught rice field eel, and a large catch , The advantage of good trapping effect, effectively overcomes the defects that the existing bottom net catches ricefield eels that are easy to be frightened, squeezed, bitten each other, easy to lack oxygen, and easy to be injured
