Description

The invention relates to an intake and drainage system for waste water and Faeces according to the preamble of claim 1.

From DE PS 35 46 563 a vacuum sewage system is known, the a manifold as an inflow and a sewer connection pipe as an outlet has connected to each other via an arcuate pipe run are, which forms a siphon. The vacuum system is partly pre-assembled in buried the ground and forms a connection station. Next is one Protective container provided, partially through the sewage pipes will. In addition, the known vacuum sewage system shows separa te pipes used for air intake.

For tent, caravan camping, rest, market and other public places there is no intake and sewage system in which as a connection station Dirty water and faeces from vehicles and / or portable  Tanks in a simple manner in a sewer system with gradient sewage pipes can be initiated.

The known vacuum sewage system according to DE PS 35 46 536 also modified as a gradient sewage system, not suitable for an on The central acceptance and drainage system for wastewater and faeces final station.

There are different constructions for sewage and faeces closing stations for caravans. These constructions are in the middle lungsblatt No. 1/94 "Mobil" of the Association of German Caravan and Motorhome manufacturer e.V. (VDWH).

However, these constructions also have various shortcomings. In particular special these constructions are not different for the connection of the most suitable designs of caravan vehicles.

Therefore, it is an object of the invention a recording and drainage system for Wastewater and faeces to create that as a unified connection station for various caravan vehicles easily pre-assembled in buried the soil and connected it to a gradient sewer system can be.

The object of the invention is solved by the features of claim 1.

According to the invention there is an uptake and drainage system for waste water as well as feces from a pre-assembled protective container that has a siphon has, to which on the inlet side at least one downpipe with an circuit for sewage hoses and portable holding tanks is formed.  

According to a development of the invention, there are preferably two downspouts provided, the one downpipe for connecting sewage chen and the other downpipe for connecting portable holding tanks serves.

The invention is particularly intended for the following locations:

• - Service stations and car stops along the highway, leaving a caravan already on long journeys the portable sewage and If necessary, the waste-holding tank can be disposed of earlier. An uncontrolled The emptying of the waste-holding tank in the landscape becomes like this avoided.
• - Campsite operators have the opportunity to set up their pitches for Camping vehicles inexpensively to the comfort stand to build. For example, a caravan driver needs the portable one No longer carry the waste-holding tank to a distant station. The caravan driver thus advantageously finds all of them other connections for sewage and faeces in his rented stand before. Likewise, in the Ka according to the invention a drinking water connection can be integrated.
• - Other public places, such as petrol stations, fairgrounds, flea markets te, exhibition center, marketplaces, etc. can be retrofitted equip.
• - Boat port to drain sewage and faeces into the sewer system to initiate at the quay.

In addition, the duct connection system according to the invention has the following further advantages:
the system is frost-proof;
the system is inexpensive;
the system is easy to service;
the system is available pre-assembled;
the system avoids false introductions;
the system can be made watertight;
the system provides fall protection in the event of a fault;
the system meets environmental requirements;
the system offers comprehensive groundwater protection;
the system can be easily adapted to the space available.

The invention is described in more detail below with reference to the drawing. It shows:

Fig. 1 is a sectional view of an embodiment of the invention.

Fig. 1 shows a receiving and drainage system for waste water and feces, which is particularly suitable as a connection station for buses, campers, trucks, etc., which are equipped with a built-in or portable waste water and / or waste holding tank.

The system thus forms a connection point, which is partly preassembled and provided with additional connection pipes at the point of installation, into which soil 11 is dug. The system works as a gradient sewage system. Such a system can be provided for each caravan site. In this way, a system for discharging the waste water can be assigned to every user of a campsite.

It is also important that the system consists of a frost-proof Schutzbehäl ter 1 , which has a siphon 12 in its cavity 36 .

The protective container 1 is double-walled, so that there is an insulating space 9 between the inner and outer container walls. As far as the protective container 1 is made from a piece of plastic, the space 1 can have a vacuum to increase the insulating effect. The insulating effect against the cold is important for reasons of frost protection in order to protect the siphon and other pipes from freezing. The protective container 1 is shown in Fig. 1 only as an example in its measurements and can, for. B. protrude much deeper into the ground.

The U-shaped siphon 12 has a manifold 14 as the inlet, which can be networked with other identical systems. On the output side, the siphon 12 has a sewer connection pipe 13 , which is preferably lower than the collecting line 14. The siphon 12 has a securely closable cleaning opening 7 , which is preferably arranged in the region of the pipe transition from the siphon 12 to the sewer connection pipe 13 .

The cleaning opening is easily screwed on from above and directed to the opening of the protective container 1 according to FIG. 1, which can be closed with a bottom plate 10 . The lid-like base plate 10 is z. B. on support shoulders 18 , which are incorporated in the walls of the protective container 1 . So that no rain water can penetrate into the protective container 1 , the base plate 10 is sealed accordingly. The bottom plate 10 can only be opened with a special tool in order to avoid the uncontrolled insertion of objects into the cavity 36 .

In the bottom plate 10 , a drain 15 may be provided, to which a screwable hose siphon 19 is connected, which is also connected to the siphon 12 . The drain 15 can be closed with a screw plug (not shown), which in turn can only be opened with a special tool when cleaning work on the top of the Bo denplatte 10 are necessary. For this purpose, the top side of the base plate 10 is provided with an inclined drainage surface 16 which opens into the drain 15 at its lowest point.

The hose siphon 19 can be insulated against freezing. It is also possible to provide 1 insulation material on the inside and outside of the protective container, which further supports frost protection. Furthermore, it is possible to install an electrical heater in the protective container 1 for frost protection in the cavity 36 . In FIG. 1 for this purpose a so-called pipe heater 40 is shown, which is preferably arranged in the region of the siphon 12th

The drain 15 can also be provided with a sieve, so that, for example, washing water, rinsing water, cleaning water for the feet, etc. can be fed directly to the channel when camping. The drain proves to be an additional advantage in particular if the protective container 1 additionally has a water connection point, which will be described later in the text with reference to a drain hole 35 in the container bottom 2 .

As far as the protective container 1 has an electrical connection to z. B. to supply the pipe heating 40 with electricity, it is additionally possible to provide a switchable lamp in the cavity 36 , for example, to be able to investigate the siphon 12 more precisely in the event of nighttime running disturbances.

In a preferred embodiment, the siphon 12 is made of transparent plastic pipes, in order to be able to quickly and without opening the cleaning opening 7 to see from the outside whether there is a blockage.

The protective container 1 pre-assembled from plastic or concrete can already have external connections 8 , which can be opened if necessary, and empty pipes for drinking water pipes, which are not shown in FIG. 1. All Roh re and connections that open into the protective container 1 or from it are welded, glued or sealed to the walls of the protective container 1 in a suitable manner so that no ker kerwater can penetrate into the cavity 36 from the soil 11 .

The protective container 1 has, as a special feature in the base plate 10, an opening 17 from which a first downpipe 3 preferably protrudes vertically. The downpipe 3 forms an extension of the siphon 12 on the inflow side. According to Fig. 1, the manifold 14 opens into the downcomer 3. The drop tube 3 may be det ausgebil in another embodiment, even directly in the bottom plate 10 and so far as possible at ground level with the bottom plate 10 lockable SEN.

The first downpipe 3 is connected to a closure 22 which can be removed with a special tool if, for example, the base plate 10 has to be removed. A conical bore 23 is provided in the closure 22 and can be locked with a cover 5 . Furthermore, a check valve 25 is provided, which is connected via a ventilation duct 24 to the inlet side of the siphon 12 . The check valve 25 serves to ensure the entry of air into the siphon 12 and to prevent the escape of gas from the siphon 12 into the environment.

In the same way, the cover 5 forms an odor trap for the conical bore 23 when it is not in use. The check valve 25 can also be formed in the cover 5 . The conical bore 23 , de ren wall can be made of rubber-elastic material, serves to receive a sewage hose splash-proof and gas-tight. The sewage hose leads, for example, dirty water and / or faeces from a camping car through the siphon directly into the sewer. Since these sewage hoses are not standardized and have different outside diameters, it is advantageous to provide the conical bore 23 .

In other embodiments, it is also possible to provide interchangeable Di punch sleeves that have a uniform outer diameter, which are adapted to a bore 23 with straight walls. The Di punch sleeves can have a longitudinal slot in the wall, which allows a lateral snapping onto a sewage hose. In this way, a spacer sleeve does not have to be pushed on from the beginning of the sewage hose. Here, the bore 23 can also have a thread into which the spacer sleeves are screwed. The spacer sleeves can also consist of two half-shells.

Instead of the conical bore 23 , a bayonet lock can be provided in order to establish a secure connection between a sewage hose of a caravan and the first down pipe 3 .

As can be seen in FIG. 1, outside the protective container 1, a second downpipe 4 opens into the collecting duct 14. The downpipe 4 protruding from the ground 11 can run through a bore 28 in a walk-in trough 27 . The tub 27 in turn has an inclined drain surface 29 which is connected to the top side of the base plate 10 via a passage 30 , 31 in the respective walls.

The tub 27 can be connected to the protective container 1 via hook-in holding elements. In other embodiments and depending on the freely available parking space for a vehicle, the trough 27 and the protective container 1 can be arranged at a distance from one another and connected to one another via a pipeline which replaces the passages 30 , 31 . The tub 27 may also have its own drain, which is connected via a Si phon to the downpipe 4 .

Should it be necessary to clean the area around the downpipe 4 , the dirty water can be supplied to the siphon 12 via the drain surfaces 29 and 16 .

These cleaning procedures may be necessary when camping user has left the sewage connection point dirty. In this way it is easily possible to quickly connect to the junction area to water and clean a watering can, so that a subsequent one Camping site users will find a clean junction.

As a further special feature, the downpipe 4 has a sleeve 21 which can be rotated through 360 ° and to which an inclined filler tube 20 connects. The downpipe 4 protrudes from the ground in about 50 to 80 cm. The filler tube 20 is, for. B. inclined as a 15 °, 30 ° or 45 ° arc relative to the downpipe 4 . The filler pipe 20 is used to discharge waste water and feces from portable tanks that can be connected to a closure 39 for the downpipe 4 , which can correspond to the closure 22 if necessary and which can be closed with a cover 6 .

The closure 39 can also be adapted in a different way to the various waste water and faecal tank systems. Due to the rotatability by 360 ° and the inclination of the filler tube 20 , emptying a portable waste water and holding tank is made considerably easier. For this purpose, a user can turn the filler tube 20 in a desired direction in which the handling of the tank during the emptying process is facilitated.

The cover 6 preferably consists of an airtight stopper with a handle 41. The stopper is pulled off if necessary in order to accommodate the outlet connection of a holding tank. The cover 6 is captively secured to the filler tube 20 by a chain and does not have to be placed on the floor. Due to the height of the filler tube, a user does not have to keep the tank bent over until the contents have been completely channeled into the channel.

The downspouts 3 , 4 and the siphon 12 are preferably made of sewer pipes with a diameter of 100 mm.

The lid 5 , 6 on the closures 22 , 39 can be equipped with a lock 37 , so that in a larger place with different stands, each having a buried protective container 1 with the connections described above, nobody can make uncontrolled discharges into the public sewer can. At various points in the system, reflective elements, e.g. B. cat's eyes 38 are attached so that a camper arriving at night with his living car can easily recognize the junction with the downpipes 3 , 4 when maneuvering.

Depending on the embodiment of the receiving and drainage system for waste water and faeces, the first downpipe 3 can also be connected to the collecting line 14 outside of the protective container 1 . Conversely, it is also possible to install the second down pipe 4 in the collecting container 1 if there is sufficient space.

In Fig. 1, a connection element for a frost-protected water tap is provided in the cavity 36 on the inside of the container bottom 2 , the outlet of which opens into a drain hole 35 . Such a water tap (hydrant) is required in particular to rinse an emptied holding tank again with process water. This rod-shaped hydrant with a riser pipe is frost-proof because the inlet valve is located on the bottom protected against frost and the water in the riser pipe can flow out after the valve is closed.

If such a hydrant is installed in the protective container 1 and connected to the drinking water line via the connections 8 , the water can flow into the soil via the drain hole 35 . The hydrant would protrude from the base plate 10 . So that the hydrant can be securely attached in the protective container 1 , holding elements are seen in the cavity 36 before.

According to Fig. 1, the fastening element for the hydrant consists of a concrete floor 32 , which has a conical connection 34 which opens into the Sic kerloch 35 : In this conical connection 34 , the hydrant is inserted. The concrete floor 32 is z. B. poured into a protective container 1 made of plastic. In this way, even with a thin-walled protective container 1, the hydrant has a secure hold on the bottom in the concrete floor 32 , which in turn has an inclined drainage surface 33 in order to allow condensed water, dripping water, etc. to flow off.

The drain hole 35 preferably has a diameter of 40 mm and can contain a check valve which allows the drain in the direction of the soil 11 . Likewise, a ma manually operable valve can be provided for the drain hole 35 and the connection 35 to close the drain. The valve can be connected to an extension in order to be able to perform the operation from the base plate 10 .

The protective container also forms a barrel-shaped collecting container, which serves environmental protection, since the drain hole 35 is generally closed and only serves to drain service water from the hydrant. To empty the protective container 1 , it is sucked out if necessary.

The closures 22 , 39 can also have several connection options in the form of the bores 23 . In this way it is possible e.g. B. assign a system between two or more neighboring campsites. For this purpose, the downpipe 3 can have two or more angled raw rends, to which the sewage and sewage system of the surrounding caravans is connected via connecting hoses via secured screw caps.

It is important in all embodiments that the closure 22 with its connecting elements is lower than the chassis of a caravan. In this way, the waste water and faeces can flow out of the caravan into the siphon 12 automatically without additional pumps.

Furthermore, it is possible to install a structure-borne sound microphone 42 preferably in the area of the duct connection pipe 13 in the wall of the protective container 1 . The connections of the structure-borne noise microphone 42 are preferably guided up to the upper edge of the protective container 1 . If there is a process disturbance, this can be detected by the presence of the Abflußgeräu cal via the structure-borne microphone 42 .

If the structure-borne noise microphone 42 is accommodated in the intermediate space 9 , it is very well protected against moisture. Since the protective container 1 forms an oscillating hollow body embedded in the ground, the protective container 1 together with a structure-borne microphone 42 can act as a sound detector. The impact sound can be used to automatically switch on an outdoor light when someone approaches the recording and drainage system at night. Here, a light step on the base plate 10 can be used to switch on the exterior light without a user having to put his container on the floor to get his hands free for a switch. This is helpful for guests of a campsite who are not so familiar with the premises and who want to tap drinking water, for example, at a tap that is close to the intake and drainage system.

An exterior light controlled in this way via the protective container 1 and a structure-borne sound microphone 42 has significant advantages over other detectors. In particular, no leaves or movements of branches cannot trigger false reports, as is the case with other detectors.

Several structure-borne microphones 42 , which are arranged together with the respective protective containers 1 in the area of sidewalks via a camping site at different locations, can be used to protect the camping site from break-ins at night. Unusual impact sound occurrences can be easily monitored from a central office at night and assigned to a specific campsite area.

Furthermore, it is possible to install a loudspeaker in the cavity 36 of the protective container 1 , which is much better protected against environmental influences and destruction there.
