Description

The invention relates to the field of non-lethal weapons, and in particular to remote-control electroshock devices (ESA), striking an object at a distance with a high-voltage current pulse through conductive channels, and can be used to disable electrical radio devices, stop cars by damaging their electrical equipment, neutralizing street disturbances both in the crowd and loners, in alarm systems as an element of active protection, etc.

ESHs are known that hit an object at distances of up to 5 meters. The best known ESH "Air Taser", which strikes an object by ejecting two live conductors. The shot is carried out using compressed gas or a spring. Domestic remote-control ESHUs (DEShUs) - Malvina-250, Scorpion-350 AT, use a replaceable Air Taser cartridge. After each shot, replace the replacement cartridge with conductors and ejection device. The disadvantages of this type of device are the one-time action - reloading is a few minutes (for the average user) and a narrow field of action (aiming point when firing) [1].

It is known DESHO, which uses a channel in the form of a jet of conductive liquid for transmitting energy of a high-voltage pulse according to patent No. US 5625525 [1], adopted by the author as a prototype. The device consists (Fig. 1) of a high-voltage generator 1, a unit for forming a conductive jet of liquid 2 and a trigger device 3. One output of the high-voltage generator is connected to a reservoir of conductive liquid in block 2, and the other is grounded. In the block forming the jet of liquid 2 contains a supply of fluid for several shots and creates a mechanical impulse for throwing the jet with gas pressure or a spring. The trigger device 3 turns on the high-voltage generator 1 at the time of the shot and activates the formation unit of the jet 2. The disadvantages of this device are the limitation of its ability to use, which is associated with the need to ensure the conditions for the flow of current through the target, for which the target must be on a conductive surface, and a short range of the device (up to 6-8 m), which is associated with the disintegration of the jet at some distance into separate fragments due to the forces of the surface tension elenia and low flow rate.

The aim of the invention is to expand the scope of DESHU and increase the range of its action.

This goal is achieved by the fact that a high-frequency high-voltage voltage generator is introduced into the well-known DESH, electrically connected to the conductive stream and having a frequency corresponding to the resonant frequency of the "DESH-conductive stream-target object" system, and the unit for forming the liquid conductive stream is made in the form of a chamber made of electrical insulation material with a conical narrowing ending in an electrically conductive nozzle, and two electrodes connected to a high constant conjugation, an electrically conductive nozzle is connected to a high-frequency high voltage generator, and a conductive substance added to the liquid reducing intermolecular friction, eg polyacrylamide, and reduce the surface tension forces, for example surfactants.

In the proposed device for transmitting a damaging electrical pulse through a single-wire line, the phenomenon of increased line conductivity for a reactive capacitive current of a frequency of tens to hundreds of kHz with a voltage of tens of kV was used when operating in the resonant mode [2]. Electric energy is transferred by bias currents; therefore, the electric conductivity of the line does not significantly limit the magnitude of the damaging electric pulse. There is no need to ground the DESHU and the object of destruction. As a conductive line, not only a conductive liquid can be used, but also any conductive medium that acts as a guide stream of electromagnetic energy, for example, a plasma stream, an ionized gas, a laser beam, etc. To ensure the damaging effect of the electrical pulse, the frequency of the high-frequency high-voltage voltage should be resonant for the load, consisting of "parasitic" capacities of the electric shock generator, the electric capacitance of an extended conductive stream and the intrinsic electric capacitance of the target.

Throwing a jet of liquid is carried out in a known manner for producing ultra-jets using an electric pulse water jet [3, Ch. 2]. As a result of a high-voltage discharge in a liquid, the pressure and temperature in the discharge channel sharply increase, a vapor-gas cavity arises, the expansion of which causes a wave shock process and the outflow of liquid from the nozzle. The intensity of the shock wave propagating along the conical part of the chamber increases, its pressure and velocity increase, as a result of which the velocity of the jet expiration reaches 1000 m / s and more. The electropulse method of forming a jet for DESA provides a large initial jet velocity, which increases the range, which is limited by the lifetime of the jet as an inextricable element. It does not require a consumable working fluid, such as gas or additional mechanical devices, and provides maximum efficiency with minimal dimensions.

An increase in the range of action can be achieved using the phenomenon of "superfluidity" of water (aqueous solutions) [4]. It was found that ordinary water turns into slippery water when a small amount of polymer compounds is introduced into it, the relative molecular weight of which reaches several million, and their regular macromolecules contain alternating oxygen atoms. The addition of hundredths of a percent of such a compound leads to an increase in the water flow rate by more than 2.5 times. This property of water is used in extinguishing fires to increase the range of the hose, in water supply and heating systems to reduce the power of the pumps. Two such polymeric compounds are known - linear polyacrylamide and polyethylene oxide or polyox (it is less stable). When limiting the TES in range, the use of polyacrylamide will reduce the discharge power of an electric spark water jet.

When the jet is flying, the forces of the surface tension of the liquid, acting more energetically along the jet, lead to the contraction of the jet into separate fragments, electrically separated from each other. To reduce this phenomenon, it is necessary to add a surfactant to the liquid (the most famous is soap). The value of this additive should be small enough so that the radial defragmentation of the jet does not begin.

Comparative analysis with the prototype shows that the proposed device is characterized by the presence of new elements and the relationships between them, which meets the criterion of "novelty." The use of significant distinguishing features in their totality provides a real wide field of application of a single-jet DESH, which allows us to conclude that the proposed technical solution meets the criterion of "inventive step".

Additional materials to the application provide an overview of electric weapons and a description of single-wire power transmission systems.

Consider the option of constructing a manual (wearable) hydroDESHU. When removing weapons from fuse S1, the device is supplied with 9-12 V power from an internal source G1. High voltage is obtained in a known two-stage way. From generator 1, short rectangular high-current low-voltage pulses are supplied to the primary windings of transformers T1 and T2. At the output of the secondary winding T1, high-voltage pulses of 400-500 V are rectified and accumulated on the capacitance C1 of 10 ... 50 μF. The choice of such a value of the output voltage T1 is associated with the minimum dimensions of the capacitance for such a voltage and with the facilitation of the switching conditions at S3. Charging time C1 determines the rate of fire of the weapon. When you pull the trigger, S3 switches, the charged capacitance C1 is connected to the electrodes 3, causing an explosive breakdown in the chamber 2, the jet is ejected from the water jet. At the same time, pulses from generator 1 through a closed switch S2 are fed to the primary winding of transformer T2, which, together with capacitance C2, forms an oscillatory circuit of shock excitation tuned to the resonant frequency of the DESO-jet-target system. This frequency should be equal to or a multiple of the frequency of generator 1. A secondary sinusoidal voltage of 30-50 kV is formed on the secondary winding T2, which closes to the jet through the conductive nozzle 5. The magnitude of the damaging current is determined by the resistance of the secondary winding T2 and additional resistors in the current circuit and for non-lethal exposure should not exceed 10 mA. The discharge chamber of the electropulse water jet 2 can have any shape, but the most appropriate is a cylindrical chamber with a conical narrowing with a nozzle on one side and a blind semicircular part with electrodes on the other to reduce internal stresses. The length of the jet should exceed the range of the DESU at least 1.5 times. With a firing range of 10 m and a jet diameter of 1.5 mm, the volume of the stream for one shot (chamber volume 2) is 25 cubic meters. see. Thus, with a liquid supply of 250 ml, DESHU can take 10 shots. Filling the chamber of the jet 2 with conductive liquid can be carried out in various ways, for example, using an electric pump for pumping or creating excessive gas pressure in the storage tank.

Consider the mechanical method of reloading. The charging cylinder 10 with a volume somewhat larger than the volume of the chamber 2 has a movable piston with a rod 9. When the piston moves to the left of the cylinder 10 from the tank 11 with a drainage air valve 8 and a supply of fluid through the open valve 7, liquid enters. Valve 6 is closed. When the piston moves to the right, the volume of fluid moves into the chamber of the jet 2 through the valve 6 with the valve 7 closed. When charging, the chamber 2 is in the nozzle position up. The rubber diaphragm 4 has a small hole sufficient to release air and retain fluid in the chamber. When fired by internal pressure, the hole in the diaphragm 4 expands to the diameter of the nozzle 5. To reduce the influence of wind, you can increase the diameter of the nozzle smoothly or stepwise or use interchangeable nozzles. Nozzle profiling also affects the flight range and jet stability, this issue is fairly well developed in the art. The ability to “guide” the barrel during firing, covering a large area of the target, both manually and during automatic scanning as part of the object’s protection system, enhances the effectiveness of the DESA and expanding the impact zone. The design parameters of this option allow it to be placed in the dimensions of a baton 40 cm long.
