Description

The utility model is designed to control moles, mice, bears and other earthen agricultural pests in suburban and garden areas.

The fight against moles and other earth pests is a laborious and not always productive process, familiar to most owners of suburban areas.

The mole occupies a special place among pests in suburban areas. The mole is a very active animal. In one day, he can dig 15 or more meters of moves at a depth of 10-50 cm. Each year, 5-8 cubs can appear in each mole family, which in a month and a half are as good as their parents. Creating a system of underground passages and holes on the site, throwing out heaps of land on the surface, damaging the root system of cultivated plants, destroying worms, moles negatively affect the condition of the site.

Therefore, the appearance of moles in summer cottages and garden plots creates a lot of problems for their owners due to the spoiled appearance of the plot and the destructive effect on plants.

The fight against moles is carried out by various methods. This is their extermination by chemical means, trapping with the help of traps, scaring away by various means.

The most modern need to recognize the method of deterrence. With poorly developed vision, moles have a very sensitive sense of smell, hearing and touch. The impact on them is used to expel moles from land.

Ultrasonic mole repellers, for example, rodent repellers Yastreb-500, WK-0675, WK-067 and others (http://www.tornado-og.ru/product-category/otpugivateli-krotov/?from=yandex -dire ...) The disadvantage of these devices is the adaptation of rodents to their effects and not always indifferent people and pets to them.

Known devices for deterring moles by acoustic and mechanically generated vibrational waves that adversely affect the acute organs of hearing and touch of moles.

Liven Enterprise's Electronic Repeller, Taiwan produces sound and vibration at intervals of 15 to 75 seconds. and various durations of the pulses themselves, and a motor with a pendulum weight enhances vibration through the thickness of the soil. For best results, the manufacturer recommends installing these repellers at a distance of 30-40 meters from each other. (http://sir-richard.ru/archive/manual/repeller/mole/instrukciya-ls-997mr.jpg).

The Ecosniper repeller LS-997MR produces sound waves and soil vibration, exerting a depressing effect on rodents and forcing moles, field mice, snakes, and bear to leave the site. According to the advertisement, this repeller allows protecting up to 1500 sq.m. plot area. (http://sir-richard.ru/borba-s-vreditelyami/otpugivateli-krotov/ls-997mr).

The device is a cylindrical aluminum body buried in the soil in the form of a pipe, one end of which is made in the form of a cone, the other in the form of a plug. Inside the housing there is a sound generator with a constantly changing radiation frequency and a vibration motor powered by D batteries (LR20).

The disadvantage of these devices is that there should not be any obstacles in the circumference of the zone of vibration propagation, for example, in the form of large stones or voids, as this reduces the effectiveness of their action. Therefore, to achieve better results, it is recommended to install several of these repellers on the site.

The closest in purpose and characteristics is the device for scaring moles and cubs that we chose for the prototype of a useful model, which contains a master oscillator that controls vibrational electromagnetic frequency converters that have built-in tunable generators, an electric power source that uses batteries. Elements are placed in a housing made in the form of a pipe with two rubber plugs, one of which is conical. Three quarters of the length of the device is buried in the ground and begins to work after installing the batteries. (Utility Model No. 96410, RU).

The use of these devices on their site did not allow us to drive moles from 6 hundred parts in the foreseeable future.

The task to which the creation of a utility model is directed is the development of an effective and economical repeller of moles, shrews, field mice, bear cubs and other earthen agricultural pests.

The technical result consists in expanding the arsenal of technical means of combating earth pests.

The technical result is achieved by the fact that the device creating a pulsed electromagnetic field containing a pulse generator and a metal ground electrode is equipped with a pulse converter connected through a high-voltage transformer to a metal ground electrode, and the power supply is provided from a household power supply 220 V, 50 Hz. In addition, the metal ground electrode is equipped with a spark gap.

In FIG. 1 presents a diagram of the claimed utility model.

A device for repelling moles and other agricultural pests contains a pulse generator 1, equipped with a pulse converter, connected to a household electrical network of 220 V, 50 Hz, connected via a high-voltage transformer 2 and a spark gap 3 with a metal ground electrode 4. The earthing switch 4 can be made as a muffled one end of a metal pipe. The earthing switch 4 is equipped with an electric spark gap 3, in the form of electrodes installed with a spark gap, connected to a high-voltage terminal of a transformer providing voltage from 5 to 25 kV. In the case of climatic modification, the transformer, ground electrode and spark gap are carried out in a protective housing 5.

As a pulse converter, the converter block according to our patent of utility model No. 134721 is used. The pulse converter unit at the input of the supply voltage contains a phase-controlled electronic switch through which the filtering storage capacitor is charged, consisting of a resistor and an operational amplifier, for example, MP 930-002 and LM2904, or R2515-002 and MCP6024. It is a case measuring 230 × 120 mm.

The pulse converter unit generates a high-voltage pulse voltage for the ground electrode and arrester. Pulse converter allows you to provide the necessary cyclic pulses. During the trial operation, the optimal exposure duration of 0.2-0.15 s and the pause duration of 1.0-2.0 s were established. This solution ensures the safety of a person who accidentally grabs an electrode that is energized, eliminating the possibility of its "riveting", which can lead to tragic consequences.

Depending on the characteristics of the soil and weather conditions, the duration of the pause can be changed.

The power consumption of the device from the industrial network does not exceed 15 watts.

The device operates as follows.

A metal ground electrode 4 with an electric spark gap 3 installed on it is buried in the soil and connected to a pulse converter. When power is applied to the earth layer, a low-frequency pulsed electromagnetic field is created. Impulse waves propagating in the soil have an uncomfortable, fearful effect on moles and other pests. In addition, an electric spark gap installed on the ground electrode system creates an additional vibrational acoustic effect in the soil layer. Optimal electric discharge is provided by regulation of the spark gap of the spark gap electrodes.

When placing the device in the soil layer, the combined effect of electromagnetic and acoustic waves, creating uncomfortable conditions for earthen rodents and other pests, allows them to be expelled from the site. According to experience, one device allows you to clean a mole of 1,500 m ² from moles in 2-3 weeks.
