Description

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

Technical field

The invention 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, Ji Jin equality county, Lvchun County, 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 solved 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, about first cray, is how to be brought to Yuanyang and to enter terraced fields actually, and nobody can say clearly.A kind of saying is, probably before and after 2006, hydromancy dragon village one 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 a plurality of 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, at terraced fields, overflow very soon.Except contention living spaces such as the fish with original, loach, 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, local villager and government be headache rather.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, and use medicine to eliminate cray, can cause environmental pollution.

Summary of the invention

For the problems referred to above, the object of this invention is to provide a kind of electric shock device that prevents cray destruction terraced fields, 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 present invention 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 comprised 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 emitter stage of the positive terminal of capacitor C 1, 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 the negative pole end of power supply, capacitor C 1, triode T4 is connected with one end of transformer T primary coil; The colelctor electrode of the negative pole end of capacitor C 2, triode T5 is 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.

Electric shock unit is comprised of resistance R 1～R2, triode T1～T2 and detection electric shock net 21.Wherein: the emitter stage of triode T1 is connected with the negative pole end of power supply; The colelctor electrode of triode T1 is connected with the contre electrode I that detects electric shock net 21; The colelctor electrode of triode T2 is connected with the I/O interface of single-chip microcomputer; The emitter stage of triode T2 is connected with the peripheral electrode II that detects electric shock net 21; The corresponding connection of I/O interface with single-chip microcomputer through resistance R 1, R2 respectively of the base stage of triode T1, T2.A and B are from detecting the contre electrode I of electric shock net 21 and the joint that peripheral electrode II draws.Correct position by detecting electric shock net 21 and be placed in the cray cave of terraced fields, makes contre electrode I be positioned at the central authorities in cave, and peripheral electrode II is positioned at the periphery in cave and contacts with hole wall.The contact portion of contre electrode I and peripheral electrode II is provided with insulation sleeve 211, and contre electrode I and peripheral electrode II are provided with insulation sleeve 212 bottom.

The operation principle of electric shock unit is: the dc source of 6V～12V for power acquisition, triode T4, T5 in circuit forms an oscillator, the DC pulse voltage that generation frequency is 3Hz, and output to the two ends of transformer T primary coil, the two ends of transformer T secondary coil, by the high pressure that produces 10,000 volts, are enough to the touching detection electric shock contre electrode I of net 21 and the cray of peripheral electrode II to hit extremely.

As shown in Figure 4, daytime by electric shock device be arranged in cray cave in terraced fields near, by detecting electric shock net 21, be arranged in the proper height place in cray cave.

The effect that detects electric shock net 21 has two: the one, as detecting net, use, and the 2nd, as high voltage shock net, use.When using as detection net, detect electric shock net 21 and be actually a switch, when triode T1, T2 conducting, under Single-chip Controlling, constantly scan pin P01, when having cray to occur and to contact contre electrode I and peripheral electrode II with health or antenna, it is 0 that single-chip microcomputer detects pin P01, at this moment control triode T1, T2 cut-off, control triode T3 conducting, the two ends of transformer T secondary coil are the high pressure that produces 10,000 volts, by evening out movable cray hit extremely.

Object of the present invention realizes like this.

Tool of the present invention has the following advantages: the physical method that shock by electricity by high voltage (1) is removed cray, has avoided throwing in drug induced ecocatastrophe in terraced fields.(2) cray of electrothanasia is edible.(3) electric shock device of the present invention is easy to manufacture, reliability is high.(4) product provided by the invention is easy to use.
