  • the invention also relates to a hydrant system comprising such an actuation device.
  • Water supply companies often face the problem that water extraction fittings (e.g. in the form of hydrant standpipes) are borrowed from third parties (e.g. to provide water supply to construction sites) and can be used in the pipe network in an uncontrolled manner. There is also the risk that third-party water extraction fittings used and the water supply company is not informed of a withdrawal. This brings with it billing problems. There is also a risk of contamination and manipulation in the pipe network. There is a permanent risk of unauthorized access to the pipe network, particularly with underground hydrants, which also poses a potential threat from terrorist attacks, for example. Today's underground hydrant can be easily opened and manipulated by anyone using tools from the hardware store (square), so that targeted contamination or poisoning of the drinking water network can be carried out relatively easily by terrorists.
  • WO 2008/099102 A2 discloses a locking and unlocking device for hydrants, in particular underground hydrants.
  • a locking means is provided which, in a locked position, blocks the movement of a valve of the hydrant, which establishes the connection to the supply network.
  • shut-off devices In addition to securing hydrants, effective protection of other shut-off devices has so far only been possible to a limited extent. Valves of shut-off devices can also be easily manipulated by unauthorized persons in other areas of application, which endangers the safety of power plants, production facilities and similar systems.
  • an improved hydrant system with such a device is to be specified.
  • an improved hydrant key is to be proposed.
  • a shut-off device equipped with the actuating device in particular a hydrant equipped with the actuating device, in particular an underground hydrant equipped with the actuating device, can be secured in a simple and practical manner. Via the actuating device, operation of the valve can only be reserved for people who have the release code for access to the shut-off device, in particular the hydrant, in particular the underground hydrant.
  • the release unit prevents the operation of the valve of the shut-off device secured by the actuating device, in particular of the hydrant, in particular of the underground hydrant, in such a way that the valve spindle cannot be rotated at least in the opening direction.
  • the control unit controls the release unit in order to release the valve operation for operating the valve on the secured shut-off device, in particular on the hydrant, in particular on the underground hydrant.
  • the key attachment e.g.
  • the release unit prevents the torque-transmitting connection between the key attachment and the valve spindle, at least in the direction of rotation that opens the valve, in order to prevent operation of the valve if there is no successful authentication of a release code. This means that the valve cannot be opened in the second switching position. Access to the shut-off device, especially the hydrant, is blocked.
  • the control unit controls the release unit so that the switchable clutch is in the first switching position when a valid release code is present. Otherwise, the switchable clutch is switched to the second switching position or remains in the second switching position in order to effectively prevent the valve from opening.
  • the can Removal of water via hydrants secured according to the invention with the actuating device can be better controlled.
  • the electrical contact surfaces provide a connection on the key attachment of the release unit, via which, in addition to power to supply the drive, the release code can also be transmitted to the control unit for authentication.
  • the actuating device itself does not have to have its own power supply, but rather an external power supply for actuating the drive can be connected via the electrical contact surfaces on the key attachment of the release unit.
  • an external power supply for actuating the drive can be connected via the electrical contact surfaces on the key attachment of the release unit.
  • the release code can also be transmitted, so that no separate contact surfaces are required.
  • the release code can be read in very conveniently and quickly via the communication unit of the control unit to enable valve operation in order to enable intuitive operation of the valve.
  • the release code stored in a data memory of the hydrant key is simply read in by the communication unit of the control unit in order to then be authenticated.
  • the clutch prevents the torque-transmitting connection of the key attachment to the valve spindle in the second switching position in the direction of rotation that opens the valve and connects the key attachment to the valve spindle in a torque-transmitting manner in the direction of rotation that closes the valve. Due to the torque transmission of the clutch in the second switching position, at least in the direction of rotation closing the valve, the valve, the shut-off device secured in this way, can be opened via the key approach even if there is no authentication, ie without a valid release code. especially the hydrant secured in this way, must at least be closed. Water extraction via the hydrant can therefore be stopped at any time, even if there is no valid release code.
  • Preventing only the opening of the valve in the second switching position takes into account the fact that the actuating device according to the invention does not actively close the hydrant valve as soon as there is no valid release code. This would also be undesirable. After opening it once, it should remain possible to draw water permanently. However, the cancellation of the torque transmission in the opening direction of the valve ensures that the valve can under no circumstances be opened without authorization in the second switching position.
  • the clutch has two spring-loaded pawls which point in the two opposite directions of rotation, one of the pawls engaging with a toothed ring of the clutch depending on the direction of rotation, adjustable via an actuating lever, and the other pawl being spaced apart from the toothed ring of the clutch.
  • This simple principle known from ratchets or ratchets in tool making, offers a particularly simple, automatically switchable clutch for the actuating device.

  • a network connection would only be possible with increased effort.
  • the self-sufficient power supply via the energy storage in the hydrant key ensures that manipulation of the actuating device on or via a mains connection is impossible.
  • a lithium-ion battery, a battery or a capacitor can be used as energy storage in the hydrant key. Electrical energy is only required for a short time at the moment the valve is opened to operate the control unit and to switch the clutch. The actual opening movement of the valve is, as usual, effected by the user's physical strength using the hydrant key. Accordingly, only little electrical energy is required.
  • An energy storage device with a comparatively low capacity that can be easily accommodated in the hydrant key is sufficient for this purpose.
  • One or more valid release codes are expediently stored in the control unit, so that authentication can be carried out very easily by comparing the read/entered release code with the stored release codes.
