Description

 The hydraulic gun module is designed to extinguish fires in forests, in open areas, in houses and vehicles, as well as to destroy obstacles during the operation of the rescue service.

 Known devices for extinguishing fires, including stationary mounted hydraulic pumps, fire hoses and manual fire trunks [F.V. Sukhorukov, V.N. Sibiryakov, Ya.A. Solomonik et al. Fire fighting equipment / Scientific editor Troitsky P.S. M .: Publishing. lit. Construction, 1965, 288 pp.].

 However, they do not allow to develop large pressures in the trunk and, accordingly, to receive a stream capable of destroying obstacles in houses, cutting tree trunks, etc., because the large flow of water from the trunk develops a large reactive force on it, requiring firefighters to compensate it physically . In addition, binding to a stationary pump does not allow a firefighter to work offline.

 Other fire extinguishing agents are known [RF Patent 2015702, publ. 1994.07.15], which can be combined into a module - these are, for example, motor-pumps and fire monitors, which reduce muscular effort when controlling the trunk and allow you to move around the uncluttered space covered by the fire.

 However, they do not allow a wide range to change the pressure in the barrel and work autonomously in cramped space volumes. In addition, the presence of fuel for powering the engines of pumping units requires constant maintenance of conditions that exclude the ignition of this fuel.

 The invention comprehensively solves the basic, problematic tasks of fire fighting. The supply of water (or other liquid) should be carried out precisely to the source of ignition and possibly from a greater distance. The feed stream, depending on the course of the combustion process, must be regulated both in form - from compact to diffuse-drop, and in force - capable of cutting metal and wood to free overflow from the trunk. It is also necessary to be able to add foaming (or other) liquid or solid particles to the water, and when extinguishing in a cramped space, even an autonomous device for the formation of a jet of liquid having the above properties.

 The technical effect is achieved by the fact that the hydraulic gun module, including its water supply unit with hydraulic tubes and a monitor with a fixed barrel housing, is additionally equipped with a power supply unit: adjustable pumps; controlled valves; cameras in whose housings fluid level and pressure sensors, electrodes surrounded by a cap; hydraulic accumulator, with inlet valves and liquid level and pressure sensors; electronic control unit and electric power unit; and the monitor additionally contains an aiming device, a removable nozzle, a movable barrel-valve, a control switch-spool, rigidly connected to the trigger.

 The water supply in a discrete way is provided by a hydraulic accumulator and a movable barrel-valve with controls that allow the accumulation of liquid under high pressure, compared with a continuous supply of liquid, accompanied by friction losses in the supply arms, which guarantees, in comparison with analogues, a longer range of the jet , and the barrel sight ensures the accuracy of its guidance.

 The shape of the jet is regulated by the installation of an appropriate barrel nozzle (smooth on the blade with a swirl, mesh, etc.) with the supply of pressure-free liquid and (or) a change in the pressure of the liquid in the hydraulic accumulator.

 The force of the jet is regulated by changing the pressure of the fluid in the hydraulic accumulator, powered by controlled internal combustion chambers. In practice, it is possible to obtain discrete jets that are pushed out by pressure of more than a dozen megapascals, which allows you to destroy solid obstacles, and a decrease in pressure to tens of thousands of pascals allows you to get a spray jet in the form of drops.

 To add solid or liquid additives to the stream, nozzles on the barrel are used, from where additives are carried away by the main stream from the barrel in the direction of the target. Mixing technology is also determined by the speed of the fluid and the discreteness of its flow through the barrel.

 In addition, the hydraulic gun module is a stand-alone device universal in designation, which, when refueling and having battery power, can also function in cramped fire-fighting spaces, during rescue operations, etc. tasks.

 The listed features of the invention provide a technical result in all cases to which the scope of legal protection applies, and in special cases. This corresponds to the use of a hydraulic gun module when: dismantling blockages in a confined space - by destroying a stream of liquid from an obstacle barrel; establishing a cable connection for delivering goods or people along it, by direct firing of a barrel of special equipment like a harpoon (capable of carrying other objects) with a jet of water; when fixed on solid supports - by hammering with a jet of liquid from the trunk of special nails and dowels. Fundamentally, the hydraulic gun module is designed to replace the fire ax and barrel of a traditional design. Analogs do not allow to implement the above set of technological operations in one design.

 The invention is illustrated by drawings, which shows a structural diagram of a hydraulic gun module.

 The hydraulic gun module consists of a conglomerate of blocks forming the parameters of the fluid supplied to the monitor, shown in figure 1, and the monitor, shown in figure 2.

 Figure 1 shows a tank 1 filled with liquid, connected by tubes through pumps 2, 3 and controlled valves 4, 5 with chambers 6 and 7, consisting of bodies 8 and 9, caps 10 and 11, electrodes 12 and 13, pressure sensors 14, 15 and level 16, 17, and additionally connected through controlled valves 18, 19 and check valves 20, 21 with a hydraulic accumulator 22, including pressure sensors 23 and level 24, connected to a controlled valve 25. In addition, figure 1 shows the block electronic control (BEU) 26, with marked numbers in circles - taps control sig alov, the ends of which are labeled similarly on the respective device connections, receiving electrical power from a power supply unit (PSU) 27. Figure 2 shows a monitor consisting of a housing 28 with an integrated barrel-valve 29, to which is attached the butt 30, handle 31, fixed a barrel 32 with a nozzle 33, a control spool 34, with a spring 35 and a trigger 36, and a sight 37.

 The device operates as follows. The operating mode is set on the control unit BEU 26, which includes pumps 2, 3, and water enters the chambers 6 and 7 until they are completely filled with air coming out from under the caps 10, 11 and the spaces between them and the bodies 8, 9 through the valve openings 4, 5 into the tank 1. The lower holes of the valves 4, 5 are closed and a small voltage is applied to the electrodes 12, 13, decomposing water into oxygen and hydrogen under the caps 10, 11, while the excess water continues to leave the space between the bodies 8, 9 and caps 10, 11 through the holes of valves 4, 5 until its below the caps will not drop to a predetermined lower level, controlled by level sensors 16, 17. Valves 4, 5 are completely closed, pumps 2, 3 are turned on, and the incoming water compresses the explosive mixture inside the caps 10, 11 to a predetermined pressure controlled by sensors 14, 15 followed by applying high voltage to the electrodes 12, 13 until a spark arises between them, the gas mixture burns and water flows under excessive pressure through valves 18, 20 and 19, 21 into the hydraulic accumulator 22. The pressure in the accumulator controls I by means of pressure sensors 23 and water level 24 with the implementation of the regulatory action on the valve 25. Upon reaching the specified parameters of the working fluid (water), the fireman receives a signal from the BEU 26 that the monitor is ready for operation and, directing the barrel 32 in the right direction with the sight 37 presses the trigger 36, compressing the spring 35 and moving the spool 34 to connect the hydraulic power chamber A to the chamber B, as a result of which the barrel-valve 29 is shifted to the butt under the action of force on its piston part due to the pressure drop between the chamber B and the drain chamber B. The movement of the barrel-valve 29 leads to the opening in its end part of the perimeter lateral holes through which the fluid from the chamber A flows directly into the cavity of the barrel-valve 29 and then through the barrel 32 and nozzles 33 to the goal of contact. After stopping pressing the trigger 36, the spring 35 expands, and the spool 35 detaches the chamber A from the chamber B, which at the same time connects to the drain chamber B, which leads, under the action of the pressure in the chamber A to the end of the barrel-valve 29, to move the entire barrel - valve 29 to the right and overlapping by the housing 28 of its side openings, i.e. Disconnect from camera A. Jet leakage stops.

 During the operation of the monitor, the control unit of the BEU 26 gives in sequence the same algorithm of control commands as described above, providing a continuous supply of water to the monitor. In case of stopping the trigger pull, the conglomerate of blocks (see Fig. 1) stops the water supply from the tank 1 only after filling the hydraulic accumulator 22 with water at a given pressure. This provides the monitor with constant availability. Accordingly, from the BEU block 26, the firefighter constantly receives information about the water parameters in the accumulator 22, the water supplies in the tank 1, about possible malfunctions, although this part of the interface is not shown in the drawings.

 The presence of adjustable pumps 2, 3 and controlled on-off valves 5, 6 allows you to create in chambers 6, 7 variable pressures and fluid levels controlled by the 16, 17 and pressure sensors 14, 15 placed in them. Electrodes 12, 13, surrounded by caps 10, 11, they allow to decompose water into oxygen and hydrogen only within the space under them by caps 10, 11, leaving a water jacket between the caps 10, 11 and the bodies 8, 9 of the chambers 6, 7, which absorbs the residual heat power when igniting the gas mixture, reducing it dissipation. The amount of accumulated detonating gas under the caps 10, 11 is determined by the task of the firefighter by the number and pressure of the fluid accumulated in the hydraulic accumulator 22 for one or more conversion cycles in the chambers 6.7. The flow of fluid from several (in this description, only two chambers) chambers to the hydraulic accumulator 22 implies such control of the processes in them when the next portion of the liquid enters under pressure slightly higher than the pressure in the accumulator 22, and if the hydraulic accumulator 22 is filled with chamber 6, 7 are disconnected from the hydraulic accumulator 22. Control of all processes, with the exception of pointing the monitor at the fire extinguishing center and pressing the trigger, as well as refueling with water and, naturally but, by setting the parameters of the jet, it is carried out by the electronic control unit 26, powered by electric power by the block 27.

 The monitor, due to the presence of a removable nozzle 33, allows you to change the shape of the main stream and introduce liquid or granular additives into it, for example, to form a foam. The presence of the trigger 36 connected to the slide valve 34 and the movable barrel-valve 29 makes it easier to control the opening and interruption of the main jet from the monitor, i.e. to receive an intermittent (discontinuous) jet, which, ceteris paribus, has a greater flight range and impact force than a continuous jet - due to a decrease in potential losses along the hydraulic path. Intermittent stream allows you to throw out of the fixed barrel additives from the nozzle 33 in portions, as well as shoot special equipment. The presence of the sighting device 37 allows you to save water when destroying small-sized obstacles (locks, tree trunks) and extinguishing local sources of flame. In addition, the monitor itself (see Fig. 2) allows the use of a hydrant to extinguish fires when directly connected to the fire hose, and, in combination with the hydraulic accumulator 22, can also receive an intermittent jet with a longer flight range due to the accumulation of pressure during the interruption of the jet ( and water volume) in the hydraulic accumulator 22 of a pressure greater than that supplied with a continuous stream - due to the absence of pressure losses in the fire hoses.

 Thus, the use of the claimed invention allows significantly, in comparison with known devices, to expand the functionality of the device for extinguishing fires and the work of rescuers.
