Description

A kind of electric shock device preventing cray from destroying terraced fields

Technical field

The invention discloses a kind of electric shock device preventing cray from destroying terraced fields.

Background technology

Yunnan Province's Hani Terrace is existing more than 1200 year history so far, and its is continuous Red River of south, whole Red River bank, 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 wisdom and the mental and physical efforts of tens of generation people, not only solve the Problems of Water Conservancy that rice does, its forest self-restraint, terrace irrigation etc. more define the vigorous ecosystem and Farming Culture, terraced fields remain the basic of Hani people's material and cultural life so far, the Hani people and the phosphorus pools great creation of getting along amiably and peacefully especially is culture and the immortal product of naturally ingenious combination.

Yuanyang does not have cray originally, and be how to be brought to Yuanyang and to enter terraced fields about first cray, nobody can say clearly actually.A kind of saying is, probably before and after 2006, hydromancy dragon village one is with an Out-migrant for work villager to be taken back by cray domestic, just breeds in terraced fields subsequently and comes, from then on get out of hand, spread to the terraced fields in the multiple small towns of this county.

The people living in the Yangtze river basin feel delicious incomparable cray, are but a disaster in local villager's eye.According to the introduction of local professional of agriculture, 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, to 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 a lot of ridge occurs countlessly deeply reach 1 meter, the hole of diameter number centimetre.Not only rise one after another and be difficult to fill up in these shrimp holes, and the mistake of the current in field can be made to affect Rice Cropping, and ridge even can be caused soft, and serious meeting causes subsides.

How to tackle cray, local villager and government rather headache.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 less more shrimp catches and is unequal to catching, energy of losing time very much again.Local government determined that the method taking medicine to eliminate carried out " encircling and suppressing " cray afterwards, and used medicine elimination cray to 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 preventing cray from destroying terraced fields, the physical method shocked by electricity by high voltage removing cray, avoids the ecocatastrophe that cray is caused at terraced fields.

For achieving the above object, the present invention is by the control unit formed with single-chip microcomputer, and the cray detecting unit be connected with the I/O interface of single-chip microcomputer and the unit that shocks by electricity form.Described electric shock unit is made up of resistance R3 ~ R4, electric capacity C1 ~ 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 the positive terminal of one end of resistance R4, electric capacity C1, the emitter stage of triode T5; The other end of resistance R4 is connected with the positive terminal of the base stage of triode T4, electric capacity C2; 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 electric capacity C1, triode T4 is connected with one end of transformer T primary coil; The negative pole end of electric capacity C2, the colelctor electrode of triode T5 are connected with the other end of transformer T primary coil; Secondary coil A, B end of transformer T holds corresponding connection with A, the B detecting the net 21 that shocks by electricity; One end of resistance R3 is connected with the base stage of triode T3, and the other end is connected with the I/O interface of single-chip microcomputer.

Cray detecting unit is made up of resistance R1 ~ 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 detecting the net 21 that shocks by electricity; 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 detecting the net 21 that shocks by electricity; The base stage of triode T1, T2 connects respectively through resistance R1, R2 are corresponding with the I/O interface of single-chip microcomputer.A and B is the joint of drawing from the contre electrode I and peripheral electrode II that detect electric shock net 21.Detection electric shock net 21 is placed on the correct position in the cray cave of terraced fields, make contre electrode I be positioned at the central authorities in cave, 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 is provided with insulation sleeve 212 bottom.

The operation principle of electric shock unit is: the dc source of power acquisition 6V ~ 12V, triode T4, T5 in circuit form an oscillator, producing frequency is the DC pulse voltage of 3Hz, and output to the two ends of transformer T primary coil, the two ends of transformer T secondary coil, by the high pressure of generation 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, the electric shock device of the application is arranged in terraced fields near cray cave by daytime, detection electric shock net 21 is arranged in the proper height in cray cave.

The effect detecting electric shock net 21 has two: one to be use as checking network, and one is use as high voltage shock net.When using as checking network, 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 appearance and with health or whisker contact contre electrode I and peripheral electrode II, microprocessor detect is 0 to pin P01, at this moment triode T1, T2 cut-off is controlled, control triode T3 conducting, the two ends of transformer T secondary coil are by the high pressure of generation 10,000 volts, and the cray that evening is out movable hits extremely.

Object of the present invention realizes like this.

Tool of the present invention has the following advantages: the physical method removing cray that (1) is shocked by electricity by high voltage, avoids and throw 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.
