Description

The invention relates to means of combating rodents (rats, mice) mainly in agriculture, at the enterprises of processing and storage of agricultural products, by repelling them.

Known methods and devices for protecting products and premises from rodents by scaring away with the help of toxic chemicals and gases, infra and ultrasound, electric current and other means.

So in Ru patent No. 2137365, A 01 M 29/00, published in bull. No. 26, 09/20/99, it is proposed to scare away rodents using pulsed optical radiation and acoustic vibrations of a certain frequency. The disadvantage of this device is that it has a limited coverage within the line of sight of the light source and is ineffective in the shading and shielding zones from the penetration of light and sound.

A device for repelling rodents by exposure to a mixture of ozone and air is known. Patent RU No. 20022413, Cl. A 01 M 19/00, published in bull. No. 41-42 in 1993. Its action is based on the fact that ozone causes irritation of the mucous membranes of the airways of rodents and thereby scares them away from protected objects. To do this, the room is filled with an ozone-air mixture with a certain concentration of ozone.

The disadvantage of this device is that in order to obtain the expected effect, the entire room is filled with an ozone-air mixture. This requires a significant amount of ozone, the bulk of which is lost without any benefit.

The closest in technical essence to the device is the device according to patent RU No. 2099944, CL. A 01 M 29/02 published in Bulletin No. 36, 1997, containing a sound generator with an acoustic device and a high voltage source with a program unit.

The disadvantage of this device is that to scare away rodents with an ozone-air mixture, it is necessary to fill the entire protected room, in addition, it takes a considerable time to fill, a lot of time is required to remove the ozone-air mixture from the room when there is a need for staff to work in it.

The technical solution to the problem is to expand the scope of the device, reduce energy costs for storage of products and reduce the cost of operation.

The problem is solved in that the device for repelling rodents, including a housing, a sound generator with an acoustic device, a program unit with a high voltage source, is equipped with an ozone-distributing flexible corrugated hollow hose made of a dielectric material resistant to ozone, inside which a high-voltage cable with protrusions is placed on the outer surface and made with alternating uninsulated sections, while the device is equipped with a reversible ventilation unit, connected flexible air duct with the ozone distribution hose, and the ozone distribution hose along its entire length has openings located in the hollows of the hose on the side adjacent to the floor.

Figure 1 shows a device for repelling rodents, and figure 2 shows a structural diagram of an ozone distribution hose (node 1, figure 1).

The device includes a housing 1, in which a sound generator 2 is placed, a high voltage source with a program unit 3, an acoustic device 5 installed above the guarded object 4, a hollow ozone distribution hose 6, a ventilation installation 7 of reverse action and an air duct 8. A high-voltage cable is placed in the hollow ozone distribution hose 9 with conductive core 10 having alternating isolated sections 11 and non-insulated sections 12. In the ozone distribution hose, holes 13 are made, and on the cable, for echeniya patency through the hose ozonovodushnoy mixture protrusions 14 are formed.

The device operates as follows.

The software unit with the high voltage source 3 is turned on. The power receivers — the sound generator 2, the high voltage source 3, the ventilation unit 7 — are streamlined, creating high voltage on the current-carrying core 10 of the high-voltage cable 9, sound signals of certain frequencies in the acoustic device 5, suspended above the guarded object 4, the ventilation unit 7 creates a given air pressure in the duct 8 and the ozone distribution hose 6 connected to it, laid on the floor around the perimeter the site occupied by the protected object 4. The operation mode of the device and equipment are controlled according to the program using the program unit 3 located in the building 1.

When a high voltage is applied to the current-carrying core 10 of the high-voltage cable 9, ozone is generated in its uninsulated sections 12, as well as ultrasonic and high-frequency electromagnetic radiation, harmful and repelling rodents.

Air under the pressure of the ventilation unit 7 moves in the ozone distribution hose 6 through the air gaps between the internal cavity of the hose 6 and the high-voltage cable 9, which have insulated sections 11 with special protrusions 14. The air captures the formed ozone molecules, mixes with it and forms an ozone-air mixture, which is discharged into the surrounding space through the holes 13 in the ozone distribution hose 6, located, in order to avoid clogging, in the hollows of the corrugation of the hose from the side facing the floor. The diameter of the holes 13 is selected so that the air pressure is uniform along the entire length of the hose.

Since the ozone-air mixture is heavier than the outside air, the ozone is concentrated at the floor surface around the perimeter of the protected object 4, while there is no need to fill the entire volume of the room with the ozone-air mixture, except for the formation of the ozone-air barrier at the same time along the entire perimeter of the protected object, while the path length and time the movement of the ozone-air mixture is significantly reduced due to the placement of uninsulated corona sections 12 of the cable 9 directly at the holes 13 in the ozone distribution hose 6.

When the concentration of the ozone-air mixture reaches the specified limits, its further supply is regulated using the program unit 3 and the ventilation unit 7.

The corona discharge forming ozone in the ozone distribution hose 6 simultaneously excites high-frequency electromagnetic radiation and ultrasonic vibrations in uninsulated sections 12 of the high-voltage cable 9, which are an additional means of repelling rodents.

In cases of work in a protected room, the ozone-air mixture with the aid of a reversing-action ventilation unit 7 through the holes 13 in the ozone distribution hose 6 is sucked out of the room, creating safe working conditions.

In order to increase work efficiency and eliminate the addiction of rodents to the ozone-air mixture, the device is equipped with a sound generator 2 and an acoustic device 5, which is placed above the protected object 4 so that the sound waves reach the directly ozonized protective barrier. The sound generator 2 is controlled by the program of block 3.

Thus, the positive effect of the proposed device is manifested in increasing the efficiency of its operation due to the combined use of three repellent rodent factors: the ozone-air mixture, sound, and high-frequency electric and ultrasonic radiation.

The use of an ozone distribution hose reduces the consumption of the ozone-air mixture, and the reversible ventilation unit allows you to regulate the flow of the ozone-air mixture into the protection zone and remove the ozone-air mixture from the room, ensuring safe working conditions.
