Description

A hinged partition and a device for partitioning a space against a fluid flowing into or out of the room

The object of the invention relates to a device for partitioning a space against a fluid flowing into or out of the room, in particular a combustible liquid.

It is known that doors or passages of a room, in particular a factory or warehouse are sealed off by flaps. A hinged partition is to ensure that a liquid does not escape from a room or enter this room. The liquids can be ^■ water, chemicals, oils or their mixtures. Such liquids or mixtures of liquids arise in particular when extinguishing water is pumped through the fire department or by a Sprenkelanlage in the room. In addition, there is a need, especially for dangerous goods storage to foreclose the camp against leakage of liquids into the environment.

Under a room is not just a building or part of a building such. As an underground car park, a workshop, a warehouse, etc. understood, but also by limitations, such as. B. walls bounded areas, which have at least one opening, for example in the form of a passage, which should be closed if necessary.

Various embodiments of devices for partitioning a space against a fluid flowing into or out of the room are known. By the US 5,460,462 a device for partitioning is known, in which a bulkhead is movable in a vertical direction. In the extended state of the bulkhead this forms a barrier. EP 0 586 356 A1 discloses a further embodiment of a device for sealing a room. This has a flexible barrier, which is formed by a tarpaulin. This tarpaulin is arranged in the ground and connected to a pivotable crossbar, through which the tarpaulin is erected.

EP 0 754 822 A2 describes a device for partitioning a room. The device has a flap pivotable about a substantially horizontal axis, which can be folded up by a drive from a recess provided in the bottom of the chamber as a function of a liquid entering the recess. This hinged partition is designed as a float. The drive comprises at least one substantially vertically movable weight, which is connected via a transmission with the axis about which the hinged partition is pivotable. The weight causes a torque about the axis which is greater than the torque acting through the weight of the hinged partition about the axis when the hinged partition has been deflected by the liquid entering the recess from its substantially horizontal position in the recess.

The hinged partition comes into contact with a seal, which is arranged in a corresponding frame that partially surrounds the opening. It is known that such a seal has a substantially rectangular cross section. The elastically formed seal is to ensure that a liquid can not get out of the room or into the room. The problem with such a device is that due to the manufacturing tolerances a complex alignment of the axle or the hinged partition is necessary to ensure that the sealing function is achieved to a sufficient extent. Due to the large amount of heat generated during fires, there is the problem that the components of the device behave thermally differently and the sealing function can not be ensured or only to a lesser extent. GB 2 403 254 A discloses a device for partitioning a room against a fluid, in particular water, flowing into the room. The device has a pivotable hinged partition, which can be pivoted about an axis from a first position to a second position. The hinged partition has a flexible seal which has projecting tabs over a transversely extending to the longitudinal axis edge of the hinged flap, which can be folded. The gasket and the flaps are connected to the hinged partition and a frame attached to the building wall. By this measure, it should be ensured that a lateral entry of a liquid between hinged partition and frame does not take place.

Proceeding from this, the present invention has the object, a device for Abschotten a room against a flowing into the room or from space fluid, in particular a combustible liquid, indicate that even at higher temperatures, especially in case of fire, essentially ensures that no fluid in or out of the room.

This object is achieved by a device for Abschott a room against a flowing into the room or from the room fluid, in particular a combustible liquid, having the features of claim 1. Advantageous developments and refinements of the invention are the subject of the dependent claims.

Device according to the invention for partitioning a space against a fluid flowing into or out of the room, in particular a combustible liquid, has a hinged partition pivotable from a first position to a second position about an axis and a frame. At least one at least partially flexible seal is provided, which has at least one tab projecting over an edge running transversely to the axis, which connected to the hinged partition and the room. Adjacent to the at least one flap, at least one shielding means is provided.

By means of this embodiment of the device according to the invention, an improved sealing is achieved. The flexible seal is on the one hand connected to the hinged partition and on the other hand with a frame which is present in the region of a passage or a passage, so that the sealing function is always present, in particular regardless of the position in which the hinged partition is located.

The inventive design of the device also allows for easier installation, since the sealing function is now almost independent of the position of the axis or the hinged partition. In addition, the inventive. Device has the advantage that an exchange of the seal is simplified. Thus, in contrast to the prior art, no specially trained personnel is necessary to replace the flexible seal.

The hinged partition is pivotable about an axis from a first position to a second position. The second position can be a variable position. There is the possibility that the hinged partition floats depending on the level of a liquid from a first position to a second position, which depends on the level. The advantage of such a device is that the hinged partition automatically comes to the first position when the level of the liquid drops again.

The flexible seal is preferably a seal which is formed like a foil. In particular, it is proposed that the seal is formed at least partially from a plastic, in particular polytetrafluoroethylene (PTFE). The properties of the seal can be adapted to the requirements. For example, it is possible to provide the seal of a material which, for example, resistant to aggressive media such. As acid, oils, gasoline, etc. is. It is also possible to provide the seal of a material which has a correspondingly high melting point. In particular, it is proposed that the seal is formed of a material which is stable even at higher temperatures. In particular, it is proposed that the seal is formed of a material which has a flame temperature of at least 150 ° C, preferably 220 ⁰ C.

According to an advantageous embodiment of the device according to the invention, it is proposed that the seal adjacent to the axis has a strip projecting beyond the hinged partition. The strip is dimensioned so that it bridges a gap between the hinged partition and, for example, a frame, wherein the strip is attached to the frame. To ensure that, for example, by vehicles or the like, when the hinged partition is passable, the seal is not damaged, it is proposed that an overrun protection is arranged over the seal. This rollover protection can be designed in the form of a pivotable cover, so that when the hinged partition is pivoted from a first position to a second position, the rollover protection is also pivoted. As a result, blocking the movement of the hinged partition is avoided by the rollover protection.

It is preferably proposed that refining means be provided by which the flap can be gathered. The refining agent brings the cloth in a suitable position when the hinged partition exerts the blocking function. The gathering agent may have various configurations. Particularly preferred is an embodiment in which the gathering agent is formed ösenförmig. In particular, it is proposed that a refining agent be provided in or at the edge region of the flap. By this device according to the invention an improved sealing function is achieved. This is particularly the case if, as a result of heat development, the components of the device behave thermally differently, the different thermal expansion of the frame and the hinged partition is compensated by the at least partially flexible seal.

A further advantage of the inventive device for partitioning a space against a fluid flowing into the room or from the room can be seen in that the assembly of the device is simplified, since compensated by the flexible seal tolerance for the positioning of the axis through the seal can be.

Because at least one shielding means is provided adjacent to the at least one flap, it is ensured that the flexible seal is protected, in particular when exposed to higher temperatures, as is the case with a fire, so that a fluid does not escape from the space or to pour into the room.

In this case, an embodiment in which the shielding means has at least one wall arranged substantially parallel to the edge of the hinged partition to form a gap is preferred. The wall is preferably at least partially formed of a material which is thermally stable at higher temperatures, in particular above 150 ⁰ C. Particularly preferred is an embodiment in which the wall is at least partially formed from a refractory material.

To further increase the safety of the seal against thermal effects, it is proposed that the wall preferably has a multilayer construction. In order to prevent, for example, flames between the wall and the edge of the hinged partition acting on the seal, it is proposed according to a still further advantageous embodiment that the edge has at least one lip, preferably a flexible lip, at least partially in the longitudinal direction of the edge extends and rests against the wall.

According to yet another advantageous embodiment, it is proposed that between the wall and the edge of a barrier is formed from a foaming material when a predetermined limit temperature is exceeded. The material may preferably be a plastic with a blowing agent which, when a predetermined temperature is exceeded, changes to a gaseous state and thus leads to foaming of the plastic. Alternatively or additionally, the material may be a thermoplastic material which is compressed at ambient temperature and expands under the action of heat.

The wall and / or the rim may be at least partially coated with such a material.

According to yet another advantageous embodiment of the device is proposed that the hinged partition has at least one movable in the direction of the wall component. This component is preferably designed such that the component comes to bear against the wall when the hinged partition is pivoted from the first position to the second position. In this case, a triggering mechanism can be provided, which releases the component, which is preferably under spring tension, so that this component is moved in the direction of the wall. By this measure, a flame-tight closure between the hinged partition and the wall is essentially achieved.

According to yet another advantageous embodiment of the device is proposed that at least one substantially arcuate cover is provided, which at least partially covers the wall and an edge region of the hinged partition. This arcuate cover ensures that, for example, flammable liquids can not enter the region of the lateral seals of the hinged partition.

According to a still further advantageous embodiment of the device, it is proposed that at least one substantially arc-shaped flame segment is provided, which has at least one flame retardation. As a result, the flames ascending below the hinged partition are derived in terms of flow technology in such a way that they reduce the thermal load on the gasket.

The air flow or the orientation of the flames can be further influenced by the fact that the flame segment is arranged below the cover. The flow of the flames can be influenced by the number and design of the flame openings. In addition, flow guide bodies can be provided in the region of the flame opening.

In order to protect the particular lateral seal from the direct action of flames is proposed according to a still further advantageous embodiment of the device that in the area of the lobes fan-shaped telescoping segments are provided.

According to yet another advantageous embodiment of the invention it is proposed that a drive is provided, by means of which the flap can be pivoted about the axis. Particularly preferred is an embodiment in which a locking device is provided, by which the flap is held in the first position. With the locking device, a trigger device is connected, by means of which the flap is released, so that the flap can be pivoted to the second position. This advantageous embodiment of the device ensures that the hinged partition only then from a first position to a second position when a fluid is present. The locking device also prevents manual manipulation of the device.

The hinged partition is preferably designed as a float. The design of the hinged partition as a floating body restricts the selection of the materials to be used. In addition, the hinged partition is subject to numerous requirements, such as the ability to move over heavy equipment, heat resistance, mechanical stability and stability against aggressive media. This can have a negative impact on the costs. For attaching additional buoyancy bodies applies accordingly, since additional space is needed. If the hinged partition is designed such that it is no longer buoyant, the weight of the hinged partition can be compensated by the application of additional forces. Such compensation can be achieved, for example, by using springs.

The attachment of springs to the hinged partition is particularly advantageous if the decreasing spring action is compensated by an increase in the hydrostatic pressure. By the rotational movement of the hinged partition of the spring travel is changed, which leads to a decrease in the spring force. The hydrostatic pressure increases with increasing height of the liquid level. By the rotational movement of the hinged partition from the horizontal position to the vertical position, the torque is reduced by the weight of the hinged partition. In the combination of these forces, with a suitable spring selection, the decreasing spring force is compensated.

Instead of springs and at least one counterweight can be used. For this purpose, if necessary, corresponding deflection rollers are necessary, so that the hinged partition can be transferred by the weight of the counterweights from the horizontal to the vertical position. As a result of the resulting overall torque curve, it is achieved that the hinged bulkhead at different liquid levels lies to a large extent in the liquid and the overlying The components are ideally protected against flames and the liquid cools the hinged partition.

Particularly advantageous is the attachment of springs directly on the surface of the hinged partition. For this purpose, tensile and compression springs are particularly suitable. To fix the at least one spring no additional complex means are needed. In addition, a substantially smooth lateral completion of the hinged partition is created. As a result, the attachment of thermal insulation and flame protection is greatly simplified, since in particular no expansion for waves or Aumahmeelemente for the introduction of force is necessary. The attachment of the at least one spring is very simple and inexpensive. The spring can be mounted directly above the hinged partition, which also protects it from heat and flame. Particularly advantageous is an embodiment in which the at least one spring is arranged so that a tangential course of the spring force line takes place only after rotation of the hinged partition about its axis. This is achieved, in particular, when the angle between the fulcrum force introduction link and the pivot point spring suspension is greater than 90 degrees.

It is particularly advantageous if the hinged partition is designed essentially wedge-shaped in cross-section. As a result, a defined position of the hinged partition in a liquid is achieved. The thickness of the hinged partition here preferably decreases in the direction of the axis of rotation. The wedge-shaped design of the hinged partition also has the advantage that the total weight of the hinged partition is reduced. The decrease in the thickness of the barrier in the direction of the axis of rotation has the advantage that the center of gravity and the center of the buoyancy force are farther from the fulcrum. As a result, a better self-adjustment of the floating height is achieved, since the flap, as it penetrates further into the liquid experiences a higher increase in buoyancy force, as when the barrier is performed with a constant thickness. Likewise, if the flap continues to emerge from the liquid will cause a greater decrease in the buoyancy Reached available volume. In addition, the installation of the hinged partition or the device using a potting, in particular concrete potting, simplified. Due to the essentially wedge-shaped design of the hinged partition, essentially no air can accumulate under the hinged partition, which results in the hinged partition not being properly submerged, as a result of which the pan is not fixed correctly. This can lead to the tub, in which the hinged partition is arranged, bulging upwards at these locations, and thus the hinged partition pivots out of the intended position and thus no longer lies flush with the floor. If the hinged bulkhead is driven by vehicles, for example, the areas that bulge upwards are subject to special stress, which can result in a load on the hinged partition, since the pressure load is not forwarded.

If springs are used to move the hinged partition, then it is particularly advantageous that the springs are selected so that the hinged partition can be pivoted manually over the entire pivoting range with little manual force. This simplifies cleaning and manually checking the function of the hinged partition. In addition, the risk of injury to the operator is thereby greatly reduced. Of particular advantage is to adjust the spring force so that the hinged partition is preferably automatically locked after a manual operation in the vertical position. As a result, the cleaning of the barrier is further simplified.

Next advantages and details of the hinged partition according to the invention and the device according to the invention will be explained with reference to the embodiments illustrated in the drawing, without the subject matter of the invention being limited to these preferred embodiments.

1 shows a perspective view of an exemplary embodiment of a hinged partition 1 of a device for partitioning a space against a fluid flowing into or out of the room, in particular a combustible liquid. The hinged partition 1 is formed by a prismatic in the representation see body, which is retractable in a recess, not shown, of a floor. The hinged partition 1 is pivotable about an axis 2 from a first position to a second position. The hinged partition 1 can identify a metallic surface, for example. It may be formed by a box of metal in which a core is arranged, which is for example a core made of a plastic or the like. A fire-retardant layer can be arranged between the core and the outer jacket.

In the illustrated exemplary embodiment, the hinged partition 1 is connected to a seal 3. The seal 3 may be formed one or more parts. The seal 3 is formed like a film. Preferably, this consists of propylene tetrafluoroethylene.

Adjacent to the axis 2, the seal 3 has a strip 4. The strip 4 is connected via a bar 12 with the hinged partition 1. The connection is preferably made detachably, for example, by the strip 12 being screwed tight to the hinged partition 1, so that the strip 4 of the seal 3 is clamped to the hinged partition, as can be seen in FIG. The width of the strip 4 is dimensioned so that the strip 4 can be fixed to a frame or bottom, not shown, of the opening, which can be closed by the hinged partition.

Adjacent to the transverse to the axis 2 extending edges 5 of the hinged partition 1 tabs 6 are provided which form part of the seal 3. The tabs 6 extend substantially over the entire length of the edge 5. The blank of the tabs 6 chosen so that it is substantially quarter-circular.

From the illustration in FIG. 2, it can be seen that openings 13 are provided in the edge region 9 of the lugs 6, which openings are part of the gathering means for shirring the flap 6 form. The tabs 6 are defined by strips 14 on the hinged partition 1.

3 shows an exemplary embodiment of a device according to the invention for partitioning a space against a fluid flowing into or out of the room, in particular a combustible liquid. The device has a hinged partition 1, which is pivotable about a shaft 2 from a first position to a second position. The hinged partition 1 is sunk in a recess in the ground, so that a passage 15 is passable or accessible. The hinged partition 1 has laterally tabs 6, which are fixed by means of the fastening means 16 on the frame 8. The frame 8 can be formed for example by the masonry of a passage. There is also the possibility that the frame 8 is a steel construction, for example.

The strip 4 is also fixed to the frame 8 by means of a strip 17.

A second embodiment of the device is shown in FIG. 4 in a sectional view. The device has a hinged partition 1, which essentially corresponds to the hinged partition 1 according to FIG. The hinged partition 1 has a seal 3, which has a strip 4. The strip 4 is fixed by means of the bar 12 on the hinged partition 1 and by the bar 17 on the frame 8. Over the strip and preferably over the entire width of the passage 15, an overrun guard 18 is arranged. The rollover protection 18 is pivotable about an axis 19, so that the rollover protection of the hinged partition 1 also pivots the rollover protection 18.

Parallel to the edge 5 of the hinged partition 1, a wall 11 is arranged, which forms a lateral protection of the flap 6. Between the edge 5 and the wall 11, a gap is preferably formed which is smaller than 1 cm. Optionally, 5 ribs may be formed at the edge, through which the gap between the edge 5 and the wall 11 is reduced. Through the openings 13 of the flap 6, rings 20 extend, which are guided on a guide means 10. The guide means 10 and the rings 20 form a gathering means 7, by which the flap 6 is gathered when the folding lock 1 is transferred from the horizontal position to a vertical position.

In the illustrated embodiments, the hinged partition 1 is pivotable about an axis 2 extending substantially horizontally. This is not mandatory. There is also the possibility that the hinged partition 1 and the axle 2 are arranged so as to enable pivoting about an essentially vertical axis, for example.

The hinged partition 1 can be manufactured in a lightweight construction, in which the core of the hinged partition is equipped with an extremely light and pressure-resistant material, which allows a high loading capacity of the hinged partition. The hinged partition is preferably designed so that, for example, vehicles can drive over the hinged partition. In particular, the hinged partition is arranged in a trough, not shown, wherein the surface of the hinged partition closes with the top of the trough when the hinged partition is in the first position. In general, the tub is arranged in front of a passage 15. The passage 15 may be, for example, a gate, a door or the like. The hinged partition is preferably dimensioned so that in the second position of the hinged partition, this extends over at least the entire width of the passage, so that no liquid can flow through the passage in an adjacent room or in the vicinity of the room.

The hinged partition can be equipped with a drive. For example, this may be a drive, as is also known from EP 0 754 822 A1. Preferably, the hinged partition or the device is designed so that a locking device is provided, by means of which the hinged partition is held in the first position. The locking device cooperates with a triggering device, so that the hinged partition is released for pivoting into the second position. The triggering device preferably has a unit by means of which a liquid level is detected. The unit may be arranged adjacent to hinged partition. This is not mandatory. The triggering device can also be arranged in a different location, especially where the probability is greatest that the liquid occurs before it reaches the hinged partition.

With the triggering device, a control device is connected. The control means provides some old signals to the triggering means so that the triggering device can be actuated or m ^'CHT.

The opening device is particularly suitable for premises in which the risk of fire is relatively high.

Fig. 5 shows an embodiment of a device for partitioning a space against a fluid flowing into or out of the room. The device has a hinged partition 1 and a frame 8. Not shown in Fig. 5, the laterally provided tab of a seal which is connected to the frame and the hinged partition.

Fig. 5 shows a Abschiπnmittel 21. The shielding means 21 is formed by two substantially mutually parallel walls 22, 23, which are stationary in the illustrated embodiment. The walls 22, 23 form a multilayer wall. The wall 22 is preferably at least partially made of a material which is stable at higher temperatures, in particular above 150 ° C. In particular, the wall 22 is at least partially made of formed refractory material. The wall 23 preferably serves as mechanical protection against forces acting on the wall 22.

FIG. 6 shows a further exemplary embodiment of a device for partitioning a room. The device has two walls 22, 23 which are essentially parallel to one another and which are arranged at a distance from one another. For example, filling material may be provided between the walls 22, 23, by means of which the fire resistance of the shielding means is further increased. At the edge 5 of the hinged partition 1, a first insulating member 24 is provided in the longitudinal direction of the edge 5. The first insulating member 24 preferably forms with a projection 25 a guide 26 in which a second insulating member 27 is arranged. The second insulating member 27 abuts against the wall 22. At least one spring element 28 is arranged between the second insulating element 27 and the hinged partition 1, so that the second insulating element 27 is pressed against the wall 22. The insulating elements 24, 27 form an additional flame protection, so that a seal, not shown, is not exposed directly to flames.

The insulating elements 24, 27 at the same time form in the illustrated embodiment, a kind of labyrinth seal, which can be supplemented by further insulating. In the illustrated embodiments according to Figures 5 and 6, the walls 22, 23 are arranged stationary. This is not mandatory. There is also the possibility that at least one of the walls, preferably the wall 22, is firmly connected to the edge 5 of the hinged partition.

Figures 7 and 8 show further embodiments of a shielding means, which is suitable and intended to be used to protect a seal, not shown.

The shielding means 21 according to FIG. 7 is formed by segments 29 which can be moved relative to one another and which can be pushed into one another. The segments 29 are in the

Representation of FIG. 7 side walls 30, which are connected to the top walls 31 are. There may be two mutually parallel side walls 30 are present, which are interconnected by the top wall 31. There is also the possibility that the segments 29 each through a side wall

30 and a top wall 31 are formed, wherein substantially parallel to the side walls 30, a wall, not shown, is present, which is connected to the

Cover walls 31 adjacent. The segments 29 are pivotable about a common axis.

8 shows a further exemplary embodiment of a device with a shielding agent. The shielding means is formed by segments 29. The segments

29 have a common arcuate top wall 31. Not shown is a substantially parallel to the segment 29 with the top wall

31 connected wall. The segments 29 are pivotable about a common axis.

FIG. 9 shows a shielding means 21, which is formed by a substantially arcuate cover 32. The cover 32 is pivotable about an axis 33, which is formed substantially horizontally. The mounting of the cover 32 is selected such that the cover 32 is displaceable in the axial direction, whereby any tolerances, thermal expansions or the like can be compensated. The pivotability of the cover 32 also has the advantage of allowing access for maintenance purposes.

According to a still further advantageous embodiment of the device, the latter has a shielding means 21, which has at least one substantially arc-shaped flame segment 34, as shown in FIG. 10. The flame segment 34 has flame openings 35, so that flames which can occur below the flame segment 34 pass through the flame seams 35. In the area of the flame openings 35 are flow elements 36 is provided so that a directed flow of the gases through the flame openings and away from them is achieved.

FIG. 11 shows a combination of a cover 32 in conjunction with a flame segment 34. The cover 32 and the flame segment 34 are arranged at a distance from one another so that they form a channel 38. The channel 38 preferably has an end-side outlet opening 37, through which the hot gases can emerge from the channel 38.

For moving the hinged partition 1, at least one spring 39 is preferably arranged, which is connected to the frame 38 and the hinged partition 39. As a result, expensive drive means for folding up the hinged partition 1 is dispensed with. From the illustration according to FIG. 13, moment profiles of the hinged partition 1 are shown as an example over the angle at the maximum possible liquid level. The decreasing spring action is compensated by the increase of the hydrostatic pressure. The rotational movement of the hinged partition changes the spring travel, which also reduces the spring force of the spring. The hydrostatic pressure which acts on the hinged partition, however, increases with increasing liquid level. The rotary movement of the hinged partition from the horizontal position to the vertical also changes the lever arm and thus the torque. By suitable spring selection, the decreasing spring force is compensated. It can also be provided several springs. The springs can also have progressive spring characteristics.

Fig. 14 shows a second arrangement embodiment of the attachment of a spring 39. The spring 39 is arranged so that the angle between the angle α of the imaginary connecting lines between the axis of rotation and the two ends of the spring or their attachment points is greater than 90 degrees , From the illustration according to FIG. 15 it can be seen that the resulting moment is almost constant over the angle of rotation, whereby during manual folding up of the Hinged partition depending on the angle always the same force must be spent.

The connection between the hinged partition 1 and the frame 8 is preferably effected by means of hinges, as can be seen from FIG. 16. Particularly advantageous is an embodiment in which the hinges 40 are mounted on the top of the hinged partition 1. Such a manner of attachment has the advantage that the hinged underside is free of connecting means, which simplifies the installation of fire-resistant insulation materials, since they would otherwise have a drilling or recess or the like in order to produce an articulated connection between the hinged door and the frame. Particularly preferred is an embodiment in which the hinges are arranged so that a free longitudinal expansion of the hinged partition is possible.

Preferred is an embodiment in which a cover is provided to protect the seal 3 in the area between the hinged partition and the frame, which is preferably connected to the hinged partition and so far protrudes beyond the hinged partition, which ensures a smooth and seamless transition to the frame. This embodiment also opens a rollover protection. The driving over the hinged partition is thus possible without height differences, which is also at higher speeds, especially for unsprung vehicles an advantage. A quiet or noiseless driving over the hinged partition is achieved. For even greater safety against leakage, it is proposed to combine the seal by means of the foil-like seal and a sealing cord attached to the frame. For this purpose, a film seal is preferably used in the lower region of a possible liquid level. In the upper area a sealing cord. As a result, the space required for the side flaps is greatly reduced. In a pure seal with foil, the space required next to the valve body at least equal to the foreclosure height. If the device according to the invention used outdoors, especially where water z. B. can flow into the tub because of water, in which the hinged partition is arranged, there is the problem that an unintentional floating of the hinged partition can occur. In this case, it is advantageous to collect the accumulated water, in particular the rainwater in a front of the device by means of a drainage channel and divert before the liquid comes into the region of the hinged partition. Only when this drainage channel is overloaded and thus flooded, the liquid can reach the hinged partition.
