Definitions

  • hydraulic pressure and hydraulic energy are normally generated by pumps because this is the technically simplest, the most flexible and the most economical form of pressure generation. This is especially true when the pressure has to be maintained over long periods of time and large amounts of hydraulic energy are required.
  • hydraulic pressure generation is extremely rare and the pressure then only has to be maintained over a shorter period of time.
  • pumps are mostly used at the moment, but then they have to be constantly maintained and checked at certain intervals in the form of test runs to ensure that they are always ready for use. This is particularly difficult when the hydraulic pressure has to be available suddenly and at unexpected times in emergency situations.
  • BESTATIGUNGSKOPIE can be reached after a long time.
  • the disasters in the Mont Blanc and Tauem tunnels have shown that.
  • the invention has for its object to provide a pressure generation system that is better than conventional pumps for the rare and short-term generation of hydraulic pressure and hydraulic energy.
  • a pressure vessel is used, in which the medium to be pressurized is stored or is supplied without pressure or with a pre-pressure and then pressurized and discharged again under the effect of the pressure generated, the pressure resulting from the creation of gas, preferably of combustion gas is generated as a result of a chemical process and the gas acts directly or indirectly on the medium to be brought to a higher pressure level.
  • the pressure is generated by the combustion gases of explosive, the explosive being in a particularly easy-to-use variant of the invention in an easily replaceable cartridge.
  • the invention provides for several or a larger number of explosive cartridges which are ignited one after the other.
  • the chronological sequence of the individual ignitions is initiated by sensors and by an electronic control system.
  • a control valve arrangement preferably a proportional valve, between the pressure vessel and the outlet nozzles or the connected hydraulic device .
  • the invention provides that the gas generating the pressure is enclosed in a bubble or separated from the medium to be pressurized by a membrane.
  • the separation of pressurized gas and medium can also be done using a separating mirror.
  • the flying piston has two different diameters and works as a pressure intensifier in two coaxial cylinders, also of different diameters. It is on
  • the primary cylinder of the pressure intensifier is arranged around a turret which can be rotated about an axis and which, in corresponding receiving devices, contains a whole series of explosive cartridges, each of which has a new one
  • the invention provides that several or a whole series of pressure vessels are connected together as a battery and take over the pressure generation in succession. Furthermore, the invention provides that two pressure vessels work in alternating cycles, thereby ensuring continuous pressure generation over a longer period of time.
  • the lid flanges of the two pressure vessels are encompassed by a rotatable turret, which contains four receptacles for explosive cartridges.
  • the emptying of the pressure bottles and the subsequent refilling with hydraulic fluid as well as the discharge of the used combustion gases is controlled by electrically operated switching valves, which are switched over in an electronically monitored manner when the turret is moved.
  • the combustion gas generated after the explosive cartridge is ignited is collected at a very high pressure level in a pressure vessel and, via a control valve arrangement, preferably a proportional or reducing valve, within very narrow tolerance limits with the predetermined pressure, which is given by the hydraulic consumer is forwarded to the pressure vessel.
  • a control valve arrangement preferably a proportional or reducing valve
  • throttling points or cross-sectional constrictions can be arranged between the explosive cartridges and the pressure vessels.
  • the mode of operation of the overall system is independent of external energy supply and the external supply of pressure medium. All parts of the system are protected against extreme heat by appropriate heat insulation and can therefore also work as intended in the area of fires.
  • the pressure generating devices according to the invention When used in tunnel extinguishing systems, the pressure generating devices according to the invention are arranged at certain intervals and are put into operation immediately after a fire has broken out, independently of one another or together by means of temperature detectors, smoke detectors, infrared sensors, remote control or direct activation on site. After activating a pressure generation system, the neighboring systems are also put into operation at short intervals in order to counteract the spread of the fire in the long term.

  • Figure 1 shows an embodiment of a pressure generating device according to the invention consisting of a pressure vessel with one or more explosive cartridges, an electronic control system with sensors, a control valve arrangement and pressure mist extinguishing devices for a tunnel.
  • Control valve arrangement and tunnel do not correspond to reality in any way and are only intended to explain the functioning of the system.
  • the pressure vessel (1) is designed for an internal pressure which corresponds to the highest possible explosion pressure of the explosive cartridges.
  • the extinguishing agent - water (2) in the case shown - is due to the combustion gases (3) the explosive cartridge (4) already ignited in the illustration is pressurized and flows through the drain line (5) and the control valve arrangement (6) into the nozzle line (7), in which - depending on the shape and size of the respective tunnel (8) - numerous water nozzles (9) are located, which produce a pressurized water (19) with relatively high kinetic energy, which fills the entire tunnel cross section relatively quickly and expands according to the arrows (11) up to the tunnel wall.
  • the nozzles are designed in such a way that a pressurized water mist is created, which is composed of the finest droplets from a very specific drop size range. Due to the natural draft in the tunnel, after a relatively short spraying time, a "mist plug” arises, which not only extinguishes fires in the immediate vicinity of the mist nozzles but also drives them to more distant sources of fire. If the mist nozzles are activated on both sides of a fire, this can be ensured that one of the "fog plugs" reaches the fire and causes the extinguishing.
  • extinguishing process takes place in such a way that the fine and finest water droplets evaporate under the influence of heat in the immediate vicinity of the source of the fire and prevent the supply of oxygen. Furthermore, the high heat of vaporization of the water draws energy from the fire and causes the source of the fire to cool down immediately after it has been extinguished, so that renewed ignition after the supply of fog has ended can be excluded.
  • extinguishing mist known per se is able to extinguish large fires with extremely small amounts of water. Therefore, they are particularly suitable for extinguishing systems that work independently of external energy and water supply. In tunnels, there is the additional advantage over extinguishing outdoors that the pressure mist is enclosed in the tunnel cross-section and the entire amount of mist generated is available for the extinguishing process in this way.
  • a pressure of the order of 100 to 200 bar prevails in the nozzle line (7) before the mist nozzles (9).
  • the pressure in the pressure vessel (1) fluctuates and is relative immediately after the explosive cartridges have been ignited high, while it gradually decreases with the evacuation of the pressure vessel and the resulting expansion and cooling of the combustion gases. Since the pressure in the pressure vessel (1) must always be higher than in the nozzle line (7), further explosive cartridges (12) are arranged in the upper part of the pressure vessel, the number and size of which is such that the amount of combustion gases generated is sufficient to empty the pressure vessel completely while maintaining the required minimum pressure.
  • the pressure sensor (13) provides appropriate information to the electronic control system (14), which triggers the ignition of the next explosive cartridge via line (15). This arrangement ensures that the pressure vessel is continuously and completely emptied and that the system pressure is always above the pressure required in the nozzle line (7).
  • a control valve arrangement and one or more pressure accumulators (16) are provided.
  • This control valve arrangement expediently consists of a proportional valve.
  • the pressure accumulators serve to dampen and minimize possible pressure fluctuations in the nozzle line (7). If the pressure in the nozzle line (7) exceeds the permissible upper limit, the hydraulic actuation (18) for switching the control unit (6) is triggered via the connecting line (17). Switching takes place against the pressure of the spring (19).
  • the pressure vessel (1) and the nozzle line (7) are hydraulically separated from one another by the switching process.
  • a pressure sensor (29) which forwards corresponding information about the pressure curve to the electronic control system (14), monitors the entire processes.
  • Smoke detectors and temperature sensors as well as infrared sensors (21) are installed in the tunnel near the pressure generating devices, which enable early detection of fires at the moment of their occurrence and via the electronic control system (14) Ignite the first explosive cartridge (4). Furthermore, the electronic control systems are more neighboring
  • Pressure generating devices are linked to one another in such a way that - possibly with a slight time delay - the neighboring pressure generating devices are also activated in order to prevent the fire from spreading.
  • Various, not shown, preferably electronic monitoring devices and transmitters have the effect that the pressure activation and extinguishing process can also be carried out remotely at any time from the monitoring center outside the tunnel or manually by switches in the tunnel.
  • the pressure generating systems are independent of external energy and water supply and, including the electronic control systems and control valve arrangements, are protected against extreme heat by appropriate heat insulation, so that they are fully effective even in the event of a fire that has already broken out.
  • the mutual distance and the amount of extinguishing agent (2) of the pressure generating devices are preferably dimensioned such that the tunnel can be filled with pressurized water mist at any time and along its entire length, taking into account the normal draft.
  • Pressure generating devices of the form described above can be used not only for extinguishing purposes but for a variety of other applications in which pressure and hydraulic energy are required at relatively long intervals and over relatively short periods of time.
  • a pressure vessel (1) is shown in a schematic representation in FIG. 2, in which the combustion gases (3) and the medium (2) to be pressurized are separated from one another by a membrane (22).
