Definitions

  • the subject of the invention is an airlock with a pneumatic orifice, in the shape of a torus with an internal membrane, activated in order to close the clearance of the tunnel tube of the vacuum train system.
  • At least one tube seal contains an air cushion, which is inflated in the transport path to form an airlock in at least one tube.
  • a durable high-pressure bubble (or airbag) can be used as an airbag.
  • the airbag may contain soft polymeric material which is embedded in the tube surface and can be quickly filled with gas when a quick closure, such as an emergency, may be necessary, minimising the change in pressure in the tube.
  • the airbag may include an activatable opening in the tube to allow ambient air to flow into the interior and fill the airbag.
  • the closing valve contains at least one actuator configured to selectively move the closure to and/or from the transport route.
  • the solution includes sealing measures arranged approximately around the circumference of the airbag (e.g. when unfolded).
  • Airlock with a pneumatic orifice for the vacuum train system, inside the vacuum tunnel housing, is provided with a chamber with a folded pneumatic orifice shaped to fit the geometry of the tunnel and railroad bed, capable of completely closing the clearance of the tube/tunnel at full unfolding.
  • the pneumatic orifice consists of a torus-shaped outer element and an inner membrane made of high-tensile strength material.
  • the essence of the invention is an airlock with a pneumatic orifice, characterized in that inside the tunnel there is an orifice chamber with an inactive expansion element made up of a flexible material consisting of an external torus and an internal membrane, which is activated by compressed air produced by compressors placed in a housing.
  • the pneumatic orifice chamber with a folded expansion element is located both at the side of the tube and at the top of the tube.
  • the airlock is composed of at least one expansion element to form pneumatic elements of the airlock, which work together to close and seal the tunnel clearance.
  • the airlock with a pneumatic orifice is composed of several pneumatic elements characterized in that the elements of the airlock can be triggered sequentially in order to obtain a proper closure of the tunnel clearance.
  • the contact between the two elements of the airlock can be closed by friction forces, by means of magnets or by means of adhesive substances.
  • the airlock with a pneumatic orifice is stabilized against the tube interior surface by friction forces, by means of magnets or stabilizing rings, or by means of adhesive substances, or by means of additional pneumatic elements, which can play a stabilizing role in addition to sealing.
  • the airlock with pneumatic orifice is activated automatically or manually.
  • the invention consists in the fact that inside the tunnel there is a pneumatic orifice chamber connected with the housing construction, in which an expanding element filled with compressed air from a container or a set of compressors is placed, which in case of activation causes a quick closure of the tunnel clearance and reduces the risk of the section air lock.
  • the pneumatic elements of the airlock work together to form a tight seal of the tunnel clearance.
  • the roughened surface is the surface with an increased coefficient of friction between the tunnel and the expansion element.
  • the roughening can be achieved by increasing the roughness of the tunnel surface by grinding with an abrasive with a FEPA grit of P30-P180.
  • the second way to "roughening" the tunnel is to cover the surface of the tunnel section, which is in contact with the surface of the expansion element, with an elastomer e.g. silicone or butyl rubber (MR) by spraying. Covering the surface with elastomer also increases the coefficient of friction between the tunnel surface and the expansion element and additionally seals the airlock.
  • an elastomer e.g. silicone or butyl rubber (MR)
  • fig. 1 represents a cross-section through a vacuum tunnel with an inactive air orifice
  • fig. 2 shows the same vacuum tunnel with an active air orifice
  • fig. 3 shows the arrangement of forces acting on the orifice and the place of installation of the holding flange is marked.
  • Special variants of the solution of the invention are shown in fig. 4, where the possible position of the orifice chamber 5 in the cross-section is shown, and fig. 5 where the possibility of using a closing orifice consisting of more than one element is shown
  • fig. 6 shows the active pneumatic orifice
  • fig. 7 shows the operation of the airlock with a pneumatic orifice.
  • Pneumatic orifice 5 is defined as an expansion element with a membrane, which is active (filled with gas) during closing the tunnel clearance in order to isolate a fragment of the tunnel, while expansion element 4 is understood as a properly sewn material, closed in the orifice chamber and waiting to be activated.
  • the pneumatic orifice is designed to choke or completely close the tunnel clearance, i.e. block the flow of gases.
  • the pneumatic orifice chamber 5 is located on the side of the tunnel or at the top of the tunnel.
  • Expansion element 4 is stabilised and secured against displacement by internal rings integrated in the tunnel structure 8, by the roughness zone of the tunnel surface in the ring zone 8 or/and by magnets 9.
  • the contact between the two parts of the airlock can be closed by frictional forces, by means of magnets or by the use of adhesive substances such as polyisobutylene or similar.
  • the inner membrane 7 is made of at least two layers - a sealing layer and a structural layer.
  • the sealing layer may be made of elastomer based on synthetic rubber or similar (neoprene), while the structural layer is made of e.g. aramid fibres.
  • Expansion element 4 (torus) has a similar structure as the membrane.
  • Example of automatic operation of an airlock with a pneumatic orifice The pressure sensors are located along the tunnel at a certain distance (e.g. 200-1000 m). At a certain moment, one of the sensors detects a surge in pressure, which indicates a significant leakage of the tunnel. The information about the leakage is sent via a monitoring system to the two pneumatic locks closest to the pressure sensor. After receiving the information, the pneumatic locks are activated automatically causing the unsealed tunnel element to be cut off.
  • a certain distance e.g. 200-1000 m
  • a vehicle moving in a tube breaks down and passengers need to be evacuated. As a result, it is stopped and the operator decides to operate the airlock with pneumatic orifices adjacent to the vehicle. After the locks have been activated, the pressure in the isolated section is equalized to atmospheric pressure and passengers are evacuated through an appropriate evacuation exit.
  • the locks of the invention can be used to protect vacuum train tunnels on the route, in station zones and service tunnels, depending on safety requirements and operational needs.
