Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING

(1) An embodiment of the invention will be explained in greater detail below with reference to the drawings, in which:

(2) FIG. 1 is a schematic illustration of a rail vehicle having a tank provided internally,

(3) FIG. 2 is a part-view of the rail vehicle of FIG. 1 in the region below the tank with an emergency emptying device in the closed state, and

(4) FIG. 3 is a part-view of the rail vehicle of FIG. 1 in the region below the tank with an emergency emptying device in the open state.

DESCRIPTION OF THE INVENTION

(5) FIG. 1 shows the general structure of a rail vehicle 1 in the inner space of which there are provided vertically one above the other a fresh water tank 2 and therebelow a waste water tank 3 which are retained in a tank frame 4. The waste water tank 3 is provided with a suction line 5 which enables emptying of the waste water tank 3 at a station which is provided for that purpose.

(6) In the embodiment illustrated, both the fresh water tank 2 and the waste water tank 3 are constructed with a single shell.

(7) At a base side of the waste water tank 3 is a tank closure 6 for a connection opening (cf. FIG. 2), by means of which the waste water tank 3 can be emptied where applicable in the event of an emergency. Such a case occurs, for example, when freezing of the waste water tank 3 may be anticipated, which would lead to the destruction of the waste water tank 3.

(8) The tank closure 6 is fitted to an inner side of an unfoldable, sack-like container 8 which extends below the tank closure 6 in the folded state downward through an opening 9 into a base 10 of the rail vehicle 1 into a shaft 11 which adjoins it in a downward direction. The shaft 11 is closed at the side thereof facing a track 12 with a cover 13 which is fitted to an outer side of the shaft 11 using a clamping strip 14, with small spacing with respect to the lower side of the base 10.

(9) An edge 15 of the sack-like container 8 is releasably fitted to an outer side of the shaft 11 at a lower end of the shaft 11, which end is set back, using a clamping strip 16. Using a sack binder 17, which is also provided below the clamping strip 16 at the outer side of the shaft 11, the sack-like container 8, as will be explained below, can be closed after it has been filled.

(10) Using the emergency emptying device explained above, when the waste water tank 3 is emptied, for example, after a tank breakage and a resultant discharge of fluid, it is possible to proceed as follows:

(11) The rail vehicle 1 is first braked and parked, after which the clamping strip 14 for the cover 13 is released and the cover 13 is removed. The tank closure 6, optionally using a tool which engages in a tool receiving member 18, is then released and allowed to fall in the direction toward the track 12. The sack-like container thereby turns to the left, the tank closure 6 coming to rest on the track bed.

(12) The waste water tank 3 which has consequently been opened begins to empty, the waste water being discharged supporting an unfolding of the sack-like container 8 between the rail vehicle 1 and the track 12. The waste water can flow completely from the waste water tank 3 into the sack-like container 8. In this instance, barriers 19 between a vehicle shell and a base of the rail vehicle 1 prevent fluid from spreading on the vehicle base 10 and causing significant damage to the rail vehicle. These barriers 19 are located outside a projection face of the tank frame 4 and further toward the outer side than the feet 21 thereof.

(13) After the sack-like container 8 has been filled, the sack binder 17 is released and pushed downward over the sack-like container 8 so that it is closed. Subsequently, there is released the clamping strip 16 with which the edge 15 of the sack-like container 8 was fitted to the outer side of the shaft 11 up to this time. Consequently, the sack-like container 8 is completely released from the rail vehicle 1. Using transport loops 20 which are provided, the filled sack-like container 8 can be rolled laterally from the track 12 and be deposited outside the clearance gauge of the rail vehicle 1. For example, using a track maintenance vehicle having a lifting device, the sack-like container 8 can be collected for disposal.

(14) In another application of the emergency emptying device, damage by a tank breakage of the fresh water tank 2 located above the waste water tank 3 is intended to be minimized. To this end, wherever possible, the waste water tank 3 is first emptied using the suction line 5. Subsequently, the same procedure as above is carried out, as in the application explained above, but now with discharged fresh water and not drawn-off waste water flowing into the sack-like container 8. In this instance, fresh water which has been discharged flows past the waste water tank 3 in the direction toward the sack-like container 8.

(15) As soon as the waste water tank 3 is empty, the sack-like container 8 can be closed in the manner explained above using the sack binder 17, after which the sack-like container 8 can be removed from the rail vehicle 1. Fresh water which continues to flow may optionally be discharged directly onto the track 12.
