If the territory allocated for the pasture is large, then it can be difficult to fence it over the entire fence. And sometimes animals belonging to other owners come to someone’s fields. In all cases, an electric shepherd comes to the rescue.
This device is a tape or wire, which is easy to install on the fence or move to another place. The article will discuss how to make the device itself and the generator for the electric shepherd with her own hands.
How the device affects animals
Upon contact with a similar fence through the body of the animal, a current is passed that goes into the ground. He is not life-threatening, but the horse, for example, will remember the unpleasant sensations that he has received here and will no longer approach such a place.
The switched on device generates and delivers voltage pulses coming from the enclosing wire.
The generator for electroshepherd organizes a range, which is safe and well controlled. You can simply forget about the ropes, chains and similar devices, as well as about all the troubles associated with them.
Store kit
A generator for cattle electric shepherd can be purchased in the online store. It happens to be of foreign and domestic production. Typically, the kit includes the following components:
- a unit that supplies voltage powered by the battery or directly through the network;
- a tape with a woven bare wire (it comes in different colors);
- pegs for insulators;
- the insulators on which the tape is installed;
- wire for connecting the unit and the grounded pin;
- the pin itself.
Instead of buying
Not everyone will want to give personal money for this device. An alternative is the ability to make a generator for an electric shepherd yourself. As you can see from the kit, assemble the device under the force of any radio amateur.
The unit is best purchased at the store - it is sold separately. But if there is a pulse generator circuit for an electric shepherd, then it is also made at home. Everything else is easily assembled from what is at hand.
Useful tools at hand
A device made independently will be the most economical option.
As an electric fence use a thin wire for welding. And in order for the animals to see her, they pull on an additional tape with rags. You can immediately provide for a wide ribbon, but you will have to pay for it. True, it sags during the wind, and when wet snow falls, the latter settles and freezes on it, therefore, the conductivity can be reduced.
But for the construction of insulators, you can come up with a lot of tools, for example, a wooden stake with plastic bottles (as screws), in which two vertical slots are made and a tape is threaded through them. Or you can just wrap the column with tape. Instead of plastic bottles, some use bicycle cameras and more.
Grounding can be implemented using a conventional piece of reinforcement or a rod of iron, a little more than a meter in length. It clogs into the ground about a meter. For best performance, water well in dry weather.
To connect the block, conductor and hedge, use the so-called “crocodile” cords for cars. They are cut in half.
If you buy columns, then they will cost far not cheap. They usually require a lot, since the maximum distance from each other should be ten meters. But it is advisable to install them even more often. At firms, the posts are made of plastic. Finding flattering reviews about such devices is extremely problematic. They are only praised when a temporary installation is needed. But for a long-term stationary installation, it is better to use wooden ones made independently.
Of course, to score them will be more difficult. Hammering with a sledgehammer is unlikely to be convenient. And some get out of the situation by first driving corners of metal, and then screwing posts of wood to them. In addition, you can purchase a hand drill and use it instead of clogging.
In general, if you use the device itself and the generator for the electric shepherd correctly, it will do its job perfectly. However, when a stallion comes across too active, even such an electric fence cannot stop him. For such individuals, it is better to duplicate the fence. Although the case will be troublesome and will cost "a pretty penny", but the horse can already be saved.
Separate nuances
Make sure that the tape does not touch the ground, grass or snow. Otherwise, the battery will continuously discharge to the ground.
The animal is taught to the device. After all, if panic occurs during the first collision, then the horse can rush in the rush to the other side and tear the wire there.
In addition, in order to avoid unnecessary trouble, you need to hang up signs for people warning of the presence of tension.
Electric shepherd generator
The diagram below can be used to assemble the device. The base from the finished transformer is used, namely: the ignition coil from the machine. This is a device with a low resistance primary and high resistance secondary windings.
When pulsating, high voltage pulses occur . If in a car they act on candles, then in a processed form, the current is supplied to the electric fence.
For the operation of the device, a pulse voltage (rhythmically repeated pulses of sound frequency) is sent to the primary winding. The process is implemented on three 555 timers, where infrasound, sound vibrations and a single vibrator are assembled.
The current in the pulse generator for the electric shepherd enters the primary winding by means of a key. A voltage is generated on the secondary winding, and sound frequency pulses are output from the third timer to the transistor gate. Thus, a pulsating current occurs in the primary winding of the pulse generator for the electric shepherd.
The device is controlled by sound pulses on the fourth output A3. Triggering occurs through a logical unit level.
The ultrasonic generator is assembled on the first timer. The frequency can be tuned with a variable resistance R1.
From the third output of the first timer, the pulses go to the second output of the second timer, where a single-shot is built. Each pulse arriving at the second output of the timer becomes the cause of the generation of the corresponding pulse (the duration of which can be adjusted using the resistance R4).
The pulses of the third output go to the fourth through the resistance R6. It turns out that the second timer sets the duration of the high-voltage pulses that go to the electric fence. In this case, the first timer sets their frequency.
Through the resistance, the pulse is directed to the gate of the transistor VT1. The primary winding of the transformer is connected to the drain circuit, and alternating voltage pulses are generated on the secondary winding.
Conclusion
Thus, assembling a generator for an electric shepherd with your own hands is the most difficult of the entire manufacture of the device. Nevertheless, having basic knowledge, a ham radio can do this without difficulty.
