Abstract
An ultrasonic special fishing device for yellow catfish pertains to ultrasonic fishing device. This fishing device is equipped with a transformer, a capacitor and a triode. The output terminal of the oscillating coil of the transformer is connected to the capacitor in series. The central tap of the control coil of the transformer is connected to the emitter of the triode by resistance and the anode of the power supply; the other two terminals of the control coil are connected by the bases of the diode and triode. The central tap of the power coil of the transformer is connected to the cathode of the power supply by the shunt resistance of the ammeter and the switch; one terminal of the power coil is connected to the collector of the triode and the other terminal is connected to the collector of the other triode and thereafter connected to the ground. Voltage meters are connected to the input of the power supply in parallel and ammeters are connected to branch resistance in parallel. This fishing device is simple in structure and small in volume and thus easy to use, its oscillatory waves can produce resonance with the sleeping frequency of the yellow catfish. With this device, the yellow catfish can be caught while asleep without affecting their living habit and needs less labor intensity.
Description
Technical field
The utility model relates to a kind of ultrasonic fish-catching apparatus, the special-purpose ultrasonic fishing device of particularly a kind of ultrasonic.
Background technology
At present, when people fish in great river, big lake or water field of big area, the general use drawn in the net and casted net, can not special for arresting yellow catfish, and use the efficient that casts for fish low at the broad water surface, it is big that use draws in the net to fish labour intensity, it is very inconvenient to get fish, uses to cast net or when drawing in the net, the fish that is caught is easy to Lou catch, catching the fish that escapes because of leakage will get a fright, and therefore influence the normal growth of fish; Use when casting net catching Pelteobagrus in river, because the water of river is shallow, pasture and water, the stone riprap of river bed are many, cast net to be difficult to use, and the efficient of catching Pelteobagrus is low.
Summary of the invention
The purpose of this utility model is efficient height and the little special-purpose ultrasonic fishing device of ultrasonic of labour intensity that a kind of catching Pelteobagrus will be provided.
The purpose of this utility model is achieved in that this fish-catching apparatus has transformer, capacitor and triode, transformer has one group of oscillator coil, one group of control coil and one group of power coil, the output of one group of oscillator coil is serially connected with capacitor, and two outputs are arranged; One group of control coil has two groups of coils of symmetry, and the centre cap of control coil is connected by the emitter stage of resistance with power cathode and triode, and two ends in addition of control coil are connected with the base stage of triode by diode respectively; One group of power coil has two groups of coils of symmetry, the centre cap of power coil connects positive source by the shunt resistance and the switch of ammeter, one end of power coil is connected with the colelctor electrode of a triode, the other end is connected back ground connection with the colelctor electrode of another triode, on power input, be parallel with voltmeter, on shunt resistance, be parallel with ammeter.
Beneficial effect: owing to adopt such scheme, triode and transformer are under the effect of power supply, produce electronic, oscillator coil obtains the wave of oscillation, with produce ultrasonic after the capacitor-coupled, hyperacoustic output electrode is inserted in the river, frequency wave when its wave of oscillation is slept with yellow cartfish is identical, large quantities of yellow cartfish around this fish-catching apparatus is under the effect of the electronic sleep wave of oscillation, enter the sleep shape, yellow cartfish loses oneself's control, and people use to dip net in the hand and just yellow cartfish can be dragged for up, efficient height during catching Pelteobagrus, labour intensity is little, has reached the purpose of this utility model.This special use ultrasonic fishing device, simple in structure, volume is little, and is easy to use, and the sleep frequency of its wave of oscillation and yellow cartfish produces resonance, and yellow cartfish is captured in one's sleep, does not influence the life habit of yellow cartfish, and labour intensity is low during fishing.
