Definitions
- the present invention relates to an apparatus for combined pressure protection and air volume control in the interior of high-speed rail vehicles, wherein the functions pressure protection and air quantity are realized with a common assembly which regulates the free flow cross-section of air intake and / or Heilausblasö réelleen depending on the operating conditions.
- a simple variant in this respect is to completely close the air inlet openings with flaps or valves when exceeding predefined pressure limits.
- the disadvantage is that thus the fresh air supply to the vehicle is completely interrupted.
- the air quality in the passenger compartment is thus significantly impaired.
- so-called pressure protection systems are increasingly being used which are intended to ensure both effective pressure protection and sufficiently good air quality.
- Object of the present invention is to provide an apparatus for combined pressure protection and air flow control in the interior of high-speed rail vehicles, which requires a small space and a small number of separate modules and ensures a fast and reliable control even at high speeds.
- the device has a pressure-tight housing against pressure surges up to a size of ⁇ 10 kPa, which is configured on its surface opposite the side surface with a recess which is associated with a flap element.
- the flap element is supported by a parallel to its longitudinal axis extending at both end portions of the axis of the housing and arranged pivotably along this axis, that the recess pressure-tight starting from each position of the flap element is closable.
- the flap element is associated with a drive assembly, which is in operative connection for an exact repeatable positioning of the flap element with an electric drive such that a closing operation starting from any position of the flap element within ⁇ 50 ms can be performed.
- the electric drive is connected to an actuating element, which automatically sets a defined end position for the flap element in the de-energized state.
- This actuator can be designed as a mechanical (eg return spring) or electrical (eg supercapacitor) element.
- supercapacitor sometimes referred to as SuperCap / supercapacitors refers to a memory for an emergency voltage source for the provision of the motor itself in a certain position in the event of power failure.
- the device according to the invention is preferably suitable for air intake and exhaust openings in fast moving passenger carriages for the protection of passengers against pressure waves.
- this device also takes over the function of regulating required amounts of air, which initially flow into the car as outside air and later leave the car as used air.
- a significant advantage of this device is the space and weight-saving combination of modules for pressure protection and air flow control in the form of a specifically designed flap element that allows a geometrically free configurability as a closing element independent of other components. Further advantages result from the exclusively electrical operation waiving pneumatic assemblies. The elimination of the previously necessary pneumatic assemblies results in cost advantages for the production of passenger coaches and air conditioning systems, especially for the high-speed area.
- the electric drive also makes it possible to realize low closing times and sufficient sealing forces.
- the control of the drive ensures an exact flap positioning with a high repeatability.
- the control is either via an analog / digital input or via a BUS system, which also allows feedback.
- the drive is connected to ensure a defined end position in the de-energized state with an actuator that protects the open or closed position depending on the application target.
- the flap element is optimized to a small overall depth by this pivotable component is designed to be elongated, with the same flow cross-section, the necessary Component width - which represents the depth when turning the flap element in the open position - to be able to reduce.
- the mechanical interfaces of the flap element are designed so that they can be operated individually or even more interconnected with a drive.
- the coupling can take place in one axis and / or placed one above the other.
- Fig. 1 shows a device according to the invention in a perspective view - OPEN
- Fig. 2 shows the device according to FIG. 1 in cross section
- FIG. 3 shows a device according to the invention in a perspective view - CLOSED
- Fig. 4 shows the device according to Fig. 3 in cross section
- Fig. 5 shows a device according to the invention with modified recesses - OPEN
- the device shown in the drawing is designed for a combined pressure protection and air flow control in the interior of rail vehicles, with a use in operative connection with air intake and / or Heilausblasö réelleen of high-speed trains is to be mentioned as a preferred application in particular.
- the functions of pressure protection and air volume are realized by a common module, which regulates the free flow cross section of the air intake and / or Heilausblasö réelleen depending on the operating conditions.
- the device comprises a housing 2, which is pressure-tight against pressure surges up to a size of ⁇ 10 kPa.
- the housing 2 is mounted on a base plate 1.
- a recess 3 is configured on the opposite side of the base plate 1. This recess 3 is assigned a flap element 4.
- the flap element 4 is supported by a parallel to its longitudinal axis 5 at the two end portions of the axis 5 on the housing 2. This takes place at the one support point via a bearing point 6.
- the axis 5 is assigned a drive assembly 7.
- This drive assembly 7 stands for an exact repeatable positioning of the flap element 4 with an electrical Drive 8 in operative connection, that a closing operation starting from any position of the flap element 4 within 50 ms can be performed. Consequently, the flap element 4 can be pivoted along the axis 5, so that the recess 3 is opened or closed by the flap element 4.
- the flap element 4 has a first planar section 41 relative to the axis 5 on one side and a second planar section 42 on the other side, these sections 41 and 42 being in different planes relative to the axis 5 run. It is provided that, in the closed position (FIG. 4), the lower section 41 bears against the underside of the contour of the pressure-tight housing 2 which surrounds the recess 3. At the same time, the upper portion 42 rests on the upper side of the contour of the pressure-tight housing 2 which surrounds the recess 3.
- FIG. 5 shows a modified embodiment, in which the recess 3 comprises two separate partial recesses 31 and 32.
- each partial recess 31 or 32 is in operative connection with an associated section 41 or 42 of the flap element 4.
- the partial recesses 31 and 32 are arranged to extend parallel to each other in different planes as shown in FIG.
- these two partial recesses 31 and 32 can also be arranged in the same plane.
- also rectangular (not shown in the drawing) or V-shaped arrangements of the flap plates to each other are possible, in such arrangements, the arrival or discharge openings can be arranged on different sides.
- the electric drive 8 is connected to an actuating element (for example return spring or supercapacitor) which, when de-energized, sets a defined end position for the flap element 4.
- an actuating element for example return spring or supercapacitor
- the flap element 4 is preferably designed optimized to a small overall depth and a low inertia. This can for example be realized by the recess 3 and the recesses 31 and 32 on the housing 2 and the functionally cooperating with the recesses 3, 31, 32 flap element 4 each have a substantially greater length than width.
- the device described can be further configured.
- sensor modules for the detection of current local environmental conditions humidity, air velocity, air flow, air temperature
- the measured values acquired by the sensor modules are then evaluated by a software implemented on the drive side in order to effect a direct air volume control.
- such sensor assemblies can be provided in the inflow and / or outflow region of the baseplate 1 in order to effect a direct airflow control on the basis of these measured values.
- a further advantageous embodiment results if the mechanical interfaces of the flap element 4 are designed so that a single flap element 4 or even a plurality of interconnected separate flap elements 4 can be brought into operative connection with a single drive assembly 7.
- their coupling takes place either in one axis and / or one above the other.
- the drive element which sets a defined position for the flap element 4 in the case of pressure protection, can be actuated so that in a long-lasting pressure protection case in short periods by slight opening of the flap element 4 selectively smallest opening cross-sections in the air intake and Heilausblasö Maschinenen (but in the context of Druckschutz contacters) accessible are.
