Description

  In order to prevent the behavior of cattle, pigs, other domestic animals and wild animals, the present invention stretches a high-voltage energizing wire (bare wire), applies a voltage electric shock to the animal in contact with this wire, and moves it. The present invention relates to an electric shock method and an electric fence device in an electric fence for the purpose of limiting.

It is specified that the voltage electric shock in the electric fence conventionally used is performed at intervals of 0.75 s or more at a current of 500 mA or less for a time of 0.1 s (s is seconds) or less. For example, as shown in FIG. 3, a primary circuit is provided by providing a parallel circuit of a primary side output transformer, a timer for regulating voltage generation time, and a charging capacitor in a DC circuit in which switch elements are connected in series. The primary side output transformer and the secondary side output transformer are transformer-coupled. Therefore, the voltage accumulated in the charging capacitor is converted to a high voltage and gives an electric shock due to the high voltage.

  In the conventional electric fence device, for safety, the voltage generation time is 0.1 s or less, the current is 500 mA or less, and the voltage generation interval is 0.75 s or more (the time during which no current flows). On the other hand, when an animal becomes large (for example, a bear, a fox, etc.), there is a problem that the shock force required to repel the animal cannot be applied within the range stipulated in the law. It was. That is, there is a problem that an effective shock cannot be given to a large animal because the electric shock force cannot be increased due to three regulations of voltage, current, and voltage generation interval.

  Wild animals that run without warning in the fields between the forests often touch the electric fence wires while running at high speed, so it was difficult to give an effective electric shock in a short time.

  According to the present invention, the electric shock is increased twice or more at a total current of 500 mA or less during 0.1 s by discharging a plurality of times (for example, 4 to 10 times) during the voltage generation time of 0.1 s. Even if the current is set to 500 mA or less, the electric shock sum is increased to solve the conventional problems.

  That is, the invention of the method is an electric shock method in an electric fence that generates discharge voltage at intervals of 0.75 s or more for a time of 0.1 s or less and a current of 500 mA or less. It is the electric shock method in the electric fence characterized by giving the electric shock of times.

  The invention of the electric fencer also charges a charging capacitor with a DC voltage obtained from an oscillation circuit that uses a battery or the like (battery and general power supply) as a power source, and this charged charging voltage is passed through a switching element such as a thyristor. In an electric fence device that suddenly generates a voltage on the primary side of the output transformer and thereby obtains an electric shock high voltage on the secondary side of the output transformer, a main timer is connected in series with the input of the high voltage generation circuit. And an electric fence device characterized in that a plurality of voltage generating circuits are connected in parallel, and a sub timer is interposed in each voltage generating circuit so that the voltage is shifted and generated in a short time. In other words, one secondary side transformer is associated with all the output transformers on the primary side of each voltage generating circuit.

  Next, the charging capacitors of each voltage generation circuit have the same capacity, and the total time of voltage generation of the plurality of voltage generation circuits is a maximum of 0.1 s or less, and the repetition time is 0.75 s or more. It is.

  In the above, the number of times of voltage generation during 0.1 s is 4 to 10 times, and the time for generating one high voltage is 0.5 ms to 5 ms.

  As described above, the main timer is connected to the basic circuit, and the time during which no current flows is set to 0.75 s or more. In addition, sub-timers are connected to the circuits of the primary side transformers, respectively, and the high voltage generation time is restricted to 0.5 ms to 5.0 ms.

  The number of times of high voltage generation in each 0.1 s differs depending on the target animal, but it is effective to generate a high voltage five or more times and improve the electric shock power for large animals such as bears.

  Even if the number of times of high voltage generation for each 0.1 s increases, each discharge voltage generation time is very short (totally 0.1 s or less), and the current can be suppressed to 500 mA or less.

  On the other hand, since the magnitude of the electric shock of one high voltage is determined by the total amount of electricity, the same high voltage is larger multiple times (for example, five times) than once. However, the living body does not clearly grasp the interval of about 0.5 ms to 5 ms, and as a result, only the electric shock force is increased and accepted. As a result, the electric fence's electric shock force is increased by the number of electric shock voltages. As a result, an effect as a large electric shock is exerted on the animal, and the object can be achieved.

  According to the present invention, by increasing the number of times of electric shock (number of electric shocks) during 0.1 s (2 times or more, preferably 5 times or more), the electric shock power can be remarkably improved without increasing the maximum current value. effective.

  Therefore, the same electric fence device is used, and there is an effect that it is possible to select an optimum electric shock force for each target animal. In addition, since the current and voltage are not increased, there are various effects such as being within the regulations of safety standards and practically no risk of harm to the target animal.

  The present invention charges a DC voltage obtained from an oscillation circuit of a DC power supply to a plurality of charging capacitors, and sequentially strikes the primary side circuit for 0.5 ms to 5 ms in accordance with the order of occurrence of the strike voltage determined by a timer. A voltage is generated, and this is transformed (high voltage) by the secondary side circuit to transmit power, and an electric shock high voltage is generated a plurality of times (for example, 4 to 10 times) within a specified time (within 0.1 s).

  According to the above, it is possible to generate a high electric shock (at least twice the conventional force) within a specified current (500 mA) within a short time (within 0.1 s). Therefore, it is possible to effectively repel animals without harming animals that have come into contact with the electric wires of the electric fence.

To explain on the basis of the embodiments of the present invention in FIG. 1, DC power supply, the diode _{D 1,} resistors _R 1, 1 primary transformer _{L 1,} switch _{S 1,} and 1s repeated condenser circuit _{a 1} consisting of timer _{T 1} the circuit _{a 2} of C ₁ in parallel to form a first shot circuit a.

As described above, the primary side transformer is sequentially formed, and finally, the DC power source, the diode D _n , the resistor R _n , the primary side transformer L _n , the switch S _n , the one shot timer T _n and 0.75 s. the circuit _{d 1} composed of a repetition timer _{T 1} are connected in parallel circuit _{d 2} of the capacitor _{C n,} constituting the n-th shot circuit n. If a secondary transformer L is installed opposite to each of the primary transformers L ₁ , L ₂ , and L _n , the shot transformer circuit of the present invention is configured.

In the above embodiment, the voltage accumulated in the capacitors C ₁ , C ₂ , C _n while the repeat timer T ₁ is ON is set at regular intervals by the repeat timer T ₁ , 1-shot timer T ₂ , T _n . apply voltage to the primary side transformer _{L 1,} L 2, _{L n} in, enter at regular intervals by repeated timer _T 1, 1 shot timer _T 2, _{T n,} the high voltage from the secondary side transformer L is It is oscillated.

Thus, repeated timer _{T 1} is (has become interval 0.1s) becomes OFF, the ends oscillation. Then if the repetition timer _{T 1} is ON after 0.75 s, as described above, a plurality shots oscillates a lightning 0.5ms~5.0ms during 0.1s, giving a shock to the animal in contact with the wire Will do.

  As described above, by oscillating a plurality of shots (for example, 4 to 10 times) within 0.1 s, it is possible to give a shock that is twice to several times stronger than one shot, but the current is within 500 mA. There is no danger of harm to animals because they are being held down.
