The invention relates to security systems and can be used to protect electric power facilities. For example, to protect the power line from sticking to the poles and wires of the line of wet snow, ice and protect the lines from intruders stealing wires and other elements of energy objects.

State of the art

Known methods for removing snow and ice from various objects by impact on these objects with various devices (crowbar, pickaxe, shovel, etc.).

The disadvantage of this method is that actions to remove snow or ice are carried out manually with a destructive effect for objects and with a large delay after the appearance of ice or snow on objects.

This method is usually used to remove snow and ice from the roofs of buildings and structures. This method is almost impossible to apply for protection from snow and ice power lines, having a complex shape, large size and passing through sparsely populated areas.

Known methods for removing snow and ice from various objects by treating the surface of objects with special liquid solutions having the ability to dissolve ice and snow or make it difficult to form an ice crust on the surface of the object.

The method is applicable in air transport to protect the fuselage of aircraft from the formation of ice and to protect the surface of roads from ice.

The disadvantage of this method is that it is almost impossible to use to protect power lines from snow and ice.

A device for repelling a criminal from an object is known (RF patent No. 2084018, CL 6 G08B 15/00, publ. 10.07.97).

It contains an electronic signaling device controlling a microwave generator with an antenna.

The advantage of the device lies in the possibility of effective protection of the entire object or its part through the formation of a powerful microwave field, effectively frightening offenders by quickly heating his body.

The disadvantages of the device are poor selectivity of exposure to the microwave barrier, the complexity of the formation of the impact zone on objects of complex geometric design, such as poles, and power lines.

A device is described in the patent of the Russian Federation No. 47823, publ. September 10, 2005, class B60R 25/00, which is a user identification system containing nodes of the friend-or-foe system — an electronic alarm system installed on a guarded object (electronic alarm system) and a mobile device with an autonomous power source (user transponder) located in another area of space .

These nodes perform the recognition function "friend or foe" for a certain time after turning on the system by wirelessly exchanging encoded signals between stationary and mobile nodes of the friend or foe system. Disclosure of invention

The problem solved by the invention is to increase the level of security of the power line from adverse weather events, subjects and objects.

The technical result that can be obtained by carrying out the invention is the protection of the power line from the sticking of wet snow and ice and the breakage due to this of the wires and the fall of the line supports.

An additional technical result that can be obtained is protection against intruders stealing wires or other elements of power line structures.

To solve the problem with achieving the specified technical solution in the known device for protecting the power line, containing an electronic alarm device and a generator with a radiator, while the output of the electronic alarm system is connected to the start input of the generator, according to the invention, connected to each other, at least one sensor configured to detect adhering snow, an electronic alarm device, to Thoroe operate in a hermetic unit, and a generator with the transmitter which are intended for vibration transmission line and separating the support from the transmission line snow adhering.

Possible implementations of the method, such that:

- an electric motor with an unbalanced flywheel is used as a generator and emitter;

- power supply to the device nodes is carried out from the line itself using a matching device;

- a generator with a radiator is configured to emit sound, infrasound or ultrasonic waves;

- the sensor is configured to register subjects or objects that are on the support of the power line;

Brief Description of the Drawings

The drawing shows a functional diagram of a device according to the invention.

The best embodiment of the invention

The power line protection device (see drawing) contains an electronic alarm device 1, a generator 2, an emitter 3, a power supply 4, a sensor 5, a switch 6. The output of the electronic device 1 is connected to the starting input of the generator 2.

According to the invention, at least one sensor 5, interconnected with each other, configured to detect adhering snow and / or ice, an electronic alarm device 1, which is made in the form of a sealed unit and a generator 2 with an emitter 3, is mounted on a transmission line support. which are intended for vibration of the power line support and separation of adhering snow and / or ice from the power line. And in variants of other subjects and objects (people stealing wires, birds, animals).

The power supply to the nodes of the device can be carried out from the power line itself using a matching device of any suitable design, for example, a transformer structurally located on the support of the power line.

The device operates as follows.

Using the switch 6, the electronic device 1, which can be used as any known alarm device, is put into standby mode.

The switch 6 can be implemented in any known form. For example, together with an alarm delay timer, in the form of a remote control, interactive or satellite control system, etc.

While in standby mode, the electronic device 1 consumes little energy, and the generator 2 is turned off.

When a certain amount of snow or ice forms on the sensor 5 (and when signals from foreign objects or entities appear), the sensor 5 detects the appearance of the corresponding signals and the signal generated in it is fed to the input of the electronic alarm device 1.

The sensors 5 can be made in the form of any known sensors 5 or their combination, for example, in the form of a spring-loaded platform and a push button switch, industrially produced electronic scales, a sensor that records changes in the structure of an electric, magnetic, electromagnetic ultrasonic field, a video camera, an infrared sensor, etc. .

Using the sensor 5, the electronic alarm device 1 is activated and at its output, intended for connection to the generator 2, a signal is generated that starts the generator 2 and emitter 3 in operation.

The generator 2 and the emitter 3 can be made emitting sound, infrasound, ultrasonic waves.

A similar power line protection device can be installed on each high voltage support in the form of unified units of a single system.

By installing highly located airtight burglar alarm units with power sensors that detect people and snow on the power line poles, you can promptly scare away intruders and turn on the generator 2 and emitter 3 in time, which form the vibration of the power line poles and separate the adhering snow, the attacker, birds or other animals from this guarded facility. Due to the implementation of the generator 2 and the emitter 3 with the possibility of forming vibration signals, it is possible to expand the security (functional) capabilities of the device.

The generator 2 and the emitter 3 vibration can be performed in the form of an electric motor with an unbalanced flywheel of suitable size and power. Or, for example, a powerful loudspeaker mounted on a support. Using several such generators installed in different parts of the support, and a computer, it is possible to form various types of oscillations of the supports and wires between them.

It is advisable to implement the option when the electronic alarm device 1 is configured to recognize "friend or foe" and turn on the generator 2 with emitter 3 in the mode of deterring a subject or object registered as a "friend or foe".

As a friend or foe system, any known system can be used.

Employees of companies engaged in the maintenance of such guarded facilities should have mobile devices of a friend or foe system, for example, structurally located in the helmet of a working electrician.

The shape and design of mobile devices of the friend or foe system can be varied. Such devices can be made in the form of a watch, a mobile phone with the corresponding function, a keychain, headgear, worker's helmet, etc.

The electronic alarm device 1 can also be configured to generate radio alarms, for example, a phone call to the control room, the police, and / or sound and / or light information messages for a detected object or subject. Such radio alarms can be received and processed in a single center for the protection of power lines in a district, region, country, etc.

Industrial applicability

The power line protection device can be used to effectively protect the power line in countries where rainfall is possible in the form of wet snow and theft of wires and other elements at power facilities located in unprotected areas is possible.
