Description

FIELD OF THE INVENTION

The invention relates to electrical means of controlling rodents, mainly mice and rats, in storage, residential and other premises.

State of the art

Electrical devices for the extermination of rodents have long been known. For example, it is known a device for killing rats and mice with electric current (see patent No. 2461, IPC: А01М 23/38, 1921), including an inclined metal platform with an edge for supporting the animal, connected to one pole of the chain and connected to another pole a grate with a tip located in front of the bait. The device is open and constantly included in the electrical network, which is a danger to humans and pets. In addition, the problem of cleaning dead bodies has not been resolved.

A device for killing rodents is known (copyright certificate No. 36725, IPC: А01М 23/38, publ. 1934), in which the consumption of electric energy is carried out only at the time of the message of an electric shock, after which the device is automatically prepared for the extermination of the next animal. However, the device is very complex, while the use of a slide for rolling does not solve the problem of sanitary cleanliness, and the appearance of dead bodies scares away other animals from the device.

Known disintegrator (see patent RU No. 2063135, IPC: A01M 23/38, publ. 1996.07.10) containing electrodes in the form of concentric cylinders forming a high-frequency heating chamber, and corona electrodes. A cable with baits is missing in the central perforated cylinder. The device organizes the cleaning of the dead bodies of animals through a conveyor with scrapers, dumping the bodies into a special hopper. However, the device of the disinfestator is complex and energy-intensive due to the constant operation of the air heater and fan to distribute the smell of bait, a conveyor for cleaning bodies and maintaining the potential of the electrodes.

A device for the extermination of rodents (see US patent No. 4250655, publ. 02.17.1981), containing a housing with an entrance for the animal, inaccessible bait, placed at different stages of the path, the passage in the form of an inclined plane to the upper unfenced area connected to the source voltage by electrodes and a chamber located under the platform for collecting dead and stunned animals. The device is bulky and characterized by low efficiency due to the long passage to the means of destruction and low voltage on the electrodes that are constantly connected to a power source, while it is likely that the affected mice do not fall into the collection chamber, but remain on the site.

Known electronic trap for animals (see US patent No. 20030131522, publ. 07/17/2003), containing a housing in which there is an input chamber-trap with a means of damaging the animal with electric current and an electronic circuit with a power supply. The trap has a multifunctional processor-based electronics that allows you to determine the presence of an animal, control the "readiness" of the system for work and signal all actions through light indication. However, the trap is disposable, the body of the affected animal remains inside the trap.

Known electronic trap (see US patent No. 200550044775, publ. 03.03.2005,), including a housing in which the bait, electronic circuit and metal plate-steps connected to a source of electricity. However, the trap has the same drawback as the one mentioned above: it does not provide means for cleaning the affected body, which makes it disposable and requires human intervention.

The closest in the presence of coinciding with the claimed device structural features is the device according to the patent for invention US No. 5953853, IPC: А01М 23/38, publ. 09/21/1999, the Device is intended for catching and extermination of rats and mice and contains a camera with an entrance for the animal, placed in the depths of the bait, a sensor for monitoring the presence of the animal, an electric platform, a movable wall and a control unit based on the controller. Upon receipt of a signal from the said sensor, the controller starts the power transformer connected to the electric platform and activates the movable wall mechanism, which moves the latter along the guides, while driving the entered mouse or rat along an inclined passage upward to an electric platform to which electric current is simultaneously supplied. After the defeat of the animal, the movable wall moves further, pushing the body of the killed animal into a container to collect the affected bodies.

The device is characterized by sanitary cleanliness and high efficiency due to the coordination of the actions of all elements of the device through the controller, which ensures guaranteed destruction and cleaning of the dead body. However, the device has low reliability, due to the presence of a large number of mechanical parts (movable mechanisms, limit switches, guides), and is characterized by increased energy consumption due to (the need to perform mechanical movements of the movable wall to drive the animal, push the affected body into the collection container and return the wall to the starting position.

Disclosure of invention

The solved problem of the claimed invention is to increase the reliability of the device and reduce energy consumption while maintaining its effectiveness and sanitary cleanliness.

The problem is solved due to the fact that in the device for the extermination of rodents containing a chamber with an entrance for the animal, a bait placed in the depth of the chamber, a sensor for monitoring the presence of an animal in the chamber and its means of destruction associated with a high voltage source, means for removing affected bodies from the chamber and a control unit that connects by a signal from said sensor of the means of destruction to a high voltage source, according to the claimed invention, the means of destruction are made in the form of two electrodes, one of which placed near the bait or on one of which the bait is placed, and the other is placed near the entrance to the chamber, the sensor for monitoring the presence of the animal in the chamber is made in the form of an optocoupler, the light beam of which crosses the chamber in front of the electrode with the bait, and the means for removing affected bodies is made in the form of a generatrix the floor of the chamber of the plate mounted with the possibility of rotation around a horizontal axis, on one side of which the bait is placed, and on the other side is a counterweight mounted on the plate, while the device is equipped with EHO associated with a lock plate control unit, retaining it in horizontal position until actuation electrodes releasing it after the actuation of said body for rotation and reset and again locking plate after its return to the horizontal position and recovery light beam optocoupler.

The above set of essential features allows you to get a new positive result, namely: to significantly simplify the device, than to significantly increase its reliability, and to ensure automatic return of the plate after dumping the affected body and bringing the device to its original state, excluding the use of mechanisms for this, than to significantly reduce energy consumption .

The device has only two movable elements: a plate mounted on a horizontal axis with the possibility of rotation, and a movable clamp for horizontal position of the plate, and the means of destruction are made in the form of two electrodes interacting through the air gap. All of these elements are easy to manufacture and maintain and are characterized by a long service life. The elimination of complex mechanisms and the simplification of the device can significantly increase its reliability and ensure uninterrupted operation.

The plate is returned to its original position after the body is dumped automatically due to the counterweight, and its fixation in a horizontal position - after the restoration of the light beam of the optocoupler. In this case, the plate acts not only as a means of cleaning the affected bodies, since the plate turned relative to the horizontal position blocks the light beam of the optocoupler, which signals the control unit that the device is not ready for operation. After the plate takes a horizontal position, the light beam is restored, the latch fixes the plate - the device is ready to receive a new "visitor".

The inventive device is characterized by high efficiency of defeat and speed, which is ensured, firstly, by placing the sensor in front of the bait, which allows you to accurately diagnose the position of the animal approaching the bait, and secondly, by placing one electrode in the immediate vicinity of the bait, and the other near the entrance, which allows you to block the zone of the possible location of the animal and ensure its guaranteed defeat. The animal will certainly find itself in the zone of action of the discharge, which runs along its body from the nose to the tail. The implementation of the removal tools in the form of a rotary plate allows you to easily and simply solve the problem of cleaning the affected body, the position of which is also planned in advance by placing the bait on one side of the axis of rotation of the plate. Moreover, all the actions of the device elements are coordinated by means of a control unit that receives a signal from the sensor about the presence of an animal in the chamber, which ensures the connection of the electrodes to a high voltage source and ensures the plate is released after the animal is injured to clean the body. The return of the device to its original position is much faster than in the prototype. Thus, all the signs work together, providing reliability, energy efficiency, high speed and at the same time sanitary cleanliness and effectiveness of the lesion.

The resulting device is characterized by increased compactness.

Another distinctive feature of the device is the possibility of using any container suitable for this purpose as a collection container for affected bodies, which expands the possibilities of using the device. At the same time, the device does not exclude the possibility of equipping it with a complete container, for which purpose the connecting elements can be made on the walls of the chamber.

The prior art it is known the use of electrodes in devices for the destruction of rodents, for example, in the device according to US patent No. 4250655 and in the device of the deratizer according to patent RU No. 2063135. However, unlike the mentioned solutions, where the electrodes are under constant voltage, in the inventive device, the electrodes are connected to the high voltage source only by the signal of the control unit, which provides significant energy savings and device safety.

In patent RU No. 2072778, publ. 1997.02.10 there is a metal plate rotatable relative to the horizontal axis, equipped with a counterweight for its return to its original position and a horizontal position lock in the form of a magnet. However, unlike the mentioned solution, where live rodents are dumped, in the inventive device, the latch is connected to the control unit and ensures that the plate is held until the rodent is injured, while the operation of the latch does not depend on the weight of the animal, which occurs in the device according to patent No. 2072778.

The features of the claimed device work together: the placement of the bait, the sensor and the electrodes ensures guaranteed damage to the animal, the position of which is predicted in advance and fixed by the sensor, and the connection of the latch with the means of destruction, carried out through the control unit, ensures the removal of the already affected body.

In the specific case of the device implementation, it is advisable to equip the device with a fixed stop, made with the possibility of supporting the plate on it in a horizontal position with the counterweight side, which will prevent possible swing of the plate when it is returned to the horizontal position, increase the accuracy of its fixation and accelerate the bringing of the device to its original position.

It is advisable to remove the counterweight from the chamber so as not to distract the mouse (rat) from the bait. In this case, the counterweight is fixed on the back of the plate.

On the surface of the plate facing the camera, along the horizontal axis of rotation of the plate, you can install partitions that form the passage for the animal to the bait, which will more accurately plan the position of the animal and increase the effectiveness of its defeat.

The connection of the electrodes with a high voltage source in a particular implementation of the device can be made in the form of an electrical circuit that includes a power source, a control unit, a voltage generator, a voltage converter, a spark gap, an isolation step-up transformer and a high voltage transformer, in the secondary winding of which are included electrodes. The second input of the control unit is connected to the receiving element of the optocoupler. The control unit can be implemented, for example, based on a comparator.

An autonomous source can be used as a power source, i.e. batteries. In addition, it is possible to connect the device to a common network by using an adapter 220 V-12 V DC 0.5 A.

The preferred implementation of the optocoupler is its implementation in the form of an LED and a photodiode. For the convenience of the technological implementation of the device, it is advisable to place the LED and the photodiode on one side relative to the axis of the plate so as to ensure that the photodiode receives the LED beam reflected from the reflective element mounted on the opposite wall of the camera.

The latch can be made in the form of a core of a solenoid, the coil of which is connected through a delay unit to the output of the control unit.

The walls of the chamber and the plate are made of plastic, which is an insulator, while the smooth surface of the material contributes to a better rolling of the affected body into the container.

The implementation of the invention

The device comprises (see FIG. 1, FIG. 2) a camera 1 with an input 2 for the animal, a bait 3 located in the depth of the chamber 1, means for defeating the animal in the form of metal electrodes 4 and 5, and means for removing the affected bodies in the form of a plate 6 mounted with the possibility of rotation on the horizontal axis 7 (see figure 3), the sensor for monitoring the presence of the animal - optocoupler 8, the clamp 9 of the horizontal position of the plate 6 counterweight 10 and made on the side wall of the camera 1 emphasis 11. Optocoupler 8 includes a LED 12 and a photodiode 13. Electrode 4 placed near bait 3 one at a time away from axis 7 (with bait can be placed directly on the electrode). The electrode 5 is placed near the entrance 2. On the other side of the axis 7 from the back side of the plate 6 is mounted a counterweight 10.

The electrical part includes (see Fig. 4) a power source 14, a control unit 15, a voltage generator 16, a voltage converter 17, a spark gap 18, an isolation step-up transformer 19 and a high-voltage transformer 20, in the secondary winding of which electrodes 4 and 5. The second input of the control unit 15 is connected to the photodiode 13 of the optocoupler. To the output of the control unit 15 through the delay unit 21, for example a time relay, a latch 9 is made, made in the form of a solenoid, the core of which is an element fixing plate 6. The power source 14 is made in the form of a battery pack. The specified electrical part is placed in a separate compartment 22 adjacent to the input chamber 1. The LED 12 and the photodiode 13 are placed both on the side of the compartment 22 of the electrical part, while a reflective element 23 is placed on the opposite wall of the chamber 1.

Under the inlet chamber 1 of the device, a container 24 is installed, designed to collect the affected bodies, which can be used as any suitable container (see figure 5). The device is ready to go.

The device operates as follows.

In the initial position: the plate 6 is in a horizontal position, supported by a stop 11 and fixed by a latch 9. The passage to the bait 3 is blocked by the light beam of the LED 12 crossing the space of the chamber 1 in front of the electrode 4 with the bait 3 above the surface of the plate 6 and reflected from the reflective element 23. Photodiode 13 receives a reflected beam. Only the optocoupler works in the electrical part.

The mouse 25 enters through the input 2 into the camera 1 and, heading towards the bait 3, crosses the beam of the LED 12. The photodiode 13 provides a signal to the control unit 15, which starts the generator 16, generating a voltage of the order of 15 kHz and 10 V, and accordingly the voltage converter 17, which rectifies the latter and increases it to 100 V. Upon reaching the required voltage, the arrester 18 breaks down to the primary winding of the transformer 19 and then to the high-voltage transformer 20. By using two transformers, on the one hand, you Okoye voltage across the electrodes 4 and 5 (about 40 kV), and on the other hand - greater safety device. Through the mouse 25 from the bait to the tail passes a high voltage discharge, from which it instantly dies. Simultaneously with the start of the generator 16, the signal from the control unit 15 is supplied to the solenoid 9 through the delay unit 21. After the calculated time necessary for the electrodes to operate and the mouse is over, the core of the solenoid 9 is retracted (removed) and the plate 6 is rotated by the weight of the animal, the mouse falls into the container 24, and the plate 6 under the action of the counterweight 10 is returned to its original state. The stop 11 restricts the rotation of the plate 6, helping it to quickly take a horizontal position. After the plate 6 has taken a horizontal position and the photodiode 13 has received the beam of the LED 12, the latch 9 again fixes the plate 6. The device is ready to receive a new "visitor", the bait is not touched.

The device is automatically set to its original position after each operation and is prepared to receive the next "visitor". For one installation of the bait, the device provides the destruction of a large number of rodents.

Thus, the claimed device is an automatic compact, reliable highly effective means of extermination of rodents.
