Abstract

Retractable removal fitting above the street level and connected to a drinking water supply network Telehydrant, characterized in that on the telethrants by means of a transition coupling, a handle bar and a static water meter and an ultrasonic meter, mounted with a radio data transmission, are arranged.

Description

The invention relates to a retractable removal fitting above the street level, which is used for drinking water at events.

The supply of drinking water at events is, according to the German Association of Gas and Water e. V., worksheet W 408, guaranteed by stanchions. These are mounted on the supply network as needed. The interface is below the street level. On the one hand, high costs are incurred through the installation, cleaning and care of the standpipes and the hydrant, on the other hand, hygienic contaminants occur again and again. The mounting of the standpipe is done by the user. The withdrawal of water is mapped by means of a counter on the hydrant and the reading of the quantities consumed takes place periodically by the message of the meter readings at the delivery of the hydrant.

For the supply of events standpipes ( DE 86 28 409 U1 ) used. The assembly and disassembly, transport and preparation of the connection hydrant penetrate contaminants and germs into the supply network. The permanent aboveground installation is rejected for safety reasons and road construction authority reasons.

It is also known DE 296 12 083 U1 a retractable unit with one or more connections for water, electricity or the like, which, however, does not include remote transmission of the measurement signals.

In the DE 92 04 361 U1 a supply and disposal bollard is described. In the bollard cavity are the utilities for water and energy as well as disposal facilities for the waste water, the supply or connection facilities for the coupling with the buried supply or disposal lines and measuring or counting devices. Access is via the movable and lockable bollard segments in the shaft. No radio transmission of the measuring signals is described.

The under DE 10 2008 053 835 A1 Telehydrant ^{® shown} is described as a retractable removal fitting, but has no permanently installed measuring device with a remote data transmission and no extraction point with a safety fitting. This also applies to the under DE 20 2005 013 836 U1 . DE 203 01 272 U1 . DE 296 21 444 U1 . DE 81 25 827 U1 and EP 1 387 229 A1 described fittings and facilities.

In the WO 2014 189901 A1 and WO 2014 016625 A2 . US 2011 0187554 A1 . DE 20 2011 100 646 U1 Although described fittings transmit radio signals, however, are permanently installed above ground.

In the scope of airfields and airports, a supply column ( DE 103 24 129 A1 and WO 02 42151 A1 ), which, however, does not describe a specific application for water supply and remote data transmission.

Furthermore, there are monitoring devices for the water distribution network ( EP 2 749 860 B1 and US 2012 0004866 A1 . EP 1 077 371 A1 ), however, do not allow the removal of water or drinking water.

The Telehydrant ^® from Hawle ( DE 10 2008 053 835 A1 ) corresponds in the field submersible fittings the current state of the art.

The object of the invention is to provide a retractable removal fitting, which is arranged when used for supply above the street level and permanently connected to the drinking water supply network, but without open interface below the street level.

According to the invention the object is achieved in that mounted on a known telethrants by means of a transition coupling, a handle bar and a static water meter and an ultrasonic meter mounted with a data radio transmission.

On the static water meter a four-way cross-coupling is arranged.

Outlet fittings are attached to two ways of this coupling.

At each outlet fitting are a system separator, a female coupling and a dummy coupling.

Furthermore, an aerator is located on the four-way cross-over the static water meter.

Advantages of the removal fitting according to the invention are that potential entries of foreign substances and germs as well as hygienic impairments are minimized by reducing the constant buildup and dismantling of standpipes and the associated opening of the drinking water network.

The interface between the extraction point and the supply network is permanently raised above the street level by the Telehydrant ^® . Theft, fraud or manipulation of stanchions and thus water losses are reduced. The remote data transmission of the water meter enables location-specific, customer-specific and time-exact billing or consumption recording. The return flow of water from the mobile equipment at events is avoided by the permanently installed safety valve.

The reading of the consumption values of drinking water on site is no longer necessary.

After use, the removal fitting is emptied and sealed again submerged below the street level.

The invention will be explained in more detail using an exemplary embodiment.

The 1 shows the side view of the retractable removal device.

On a telethrante 1 are by means of a transfer clutch 2 a handlebar 3 and a static water meter with a radio data transmission 4 assembled.

On the static water meter 4 is a four-way crossover 5 appropriate. At two ways of this clutch 5 are outlet fittings 6 attached. At each outlet fitting 6 are a system separator after the EN 1717 7 , a coupling with an internal thread 8th and a blind coupling 9 ,

At the four-way cross-coupling 5 opposite the connection of the static water meter 4 An aerator is arranged.
