Description

A kind of electric shock device that prevents cray destruction terraced fields

Technical field

The utility model discloses a kind of electric shock device that prevents cray destruction terraced fields.

Background technology

Yunnan Province's Hani Terrace is existing more than 1200 year history so far, its Nan An Red River, continuous whole Red River, Yuanyang, Lvchun County and Jin Pingdengxian, and only Yuanyang County just has 170,000 mu of terraced fields within the border.The terraced fields of Yuanyang County are built on hillside, and highest number reaches 3000 grades, rare in the whole world; Over more than 1200 year, the Hani people have poured into tens of generation people's wisdom and mental and physical efforts, not only solve the Problems of Water Conservancy that rice does, its forest self-restraint, terrace irrigation etc. have more formed the vigorous ecosystem and Farming Culture, terraced fields remain the basic of Hani people's material and cultural life so far, the great creation that get along amiably and peacefully in the Hani people and sad firm mountain is especially culture and the immortal product of ingenious combination naturally.

Yuanyang does not have cray originally, is how to be brought to Yuanyang and to enter terraced fields about first cray actually, and nobody can say clearly.A kind of saying is, probably 2006 before and after, the imperial village one of hydromancy is with the villager that goes out to do manual work cray to be taken back domestic, just in terraced fields, breeds and comes subsequently, from then on gets out of hand, and spreads to the terraced fields in the multiple small towns of this county.

The people that live in the Yangtze river basin feel delicious incomparable cray, are but a disaster in local villager's eye.According to local professional of agriculture's introduction, cray have do not need artificial incubation, adaptability and fertility strong, set up kind of group velocity fast, be easy to the features such as diffusion, overflow at terraced fields very soon.Except fighting for living space with original fish, loach etc., cray also can gnaw rice crop, affects the grain yield in later stage.

Maximum harm is, cray is liked burrowing.So there is countless hole that deeply reaches 1 meter, diameter number centimetre on a lot of ridges.Not only rising one after another and be difficult to fill up in these shrimp holes, and can make the current mistake in field affect Rice Cropping, even can cause that ridge is soft, and serious meeting causes subsides.

How to tackle cray, rather headache of local villager and government.Start most the cray of terraced fields many after, be that each one carries out manual catching and killing at oneself terraced fields substantially, unusually more shrimp catches and is unequal to catching less, the energy of losing time very much again.Local government determined to take the method that medicine is eliminated to carry out " encircling and suppressing " cray afterwards, can cause environmental pollution and use medicine to eliminate cray.

Summary of the invention

For the problems referred to above, the purpose of this utility model is to provide a kind of electric shock device that prevents cray destruction terraced fields, and the physical method shocking by electricity by high voltage is removed cray, the ecocatastrophe of avoiding cray to cause in terraced fields region.

For achieving the above object, the utility model is by the control module forming with single-chip microcomputer, and the cray detecting unit being connected with the I/O interface of single-chip microcomputer and electric shock unit form.Described cray detecting unit is made up of resistance R 3～R4, capacitor C 1～C2, triode T3～T5, transformer T and power supply.Wherein: the colelctor electrode of triode T3 is connected with the positive pole of power supply; The emitter stage of triode T3 is connected with one end of resistance R 4, the positive terminal of capacitor C 1, the emitter stage of triode T5; The other end of resistance R 4 is connected with the base stage of triode T4, the positive terminal of capacitor C 2; The colelctor electrode of triode T4 is connected with the base stage of triode T5; The emitter stage of the negative pole end of power supply, the negative pole end of capacitor C 1, triode T4 is connected with one end of transformer T primary coil; The negative pole end of capacitor C 2, the colelctor electrode of triode T5 are connected with the other end of transformer T primary coil; Secondary coil A, the B end of transformer T and the corresponding connection of A, B end that detects electric shock net 21; One end of resistance R 3 is connected with the base stage of triode T3, and the other end is connected with the I/O interface of single-chip microcomputer.
