Device for protecting brook bed against e.g. snowslide, has release mechanism controllable by detection device for mass flow, where detection device is arranged at distance above retaining device
The device has a retaining device (4) movable from a resting position into a locking position by a release mechanism (7) in dependence on occurrence of a mass flow. The release mechanism is controllable by a detection device (13) for the mass flow, where the detection device is arranged at a distance above the retaining device. The detection device comprises a collection device (14) for a partial mass of the mass flow. The collection device is movably supported in a flow direction of the mass flow, and is drivably connected with the release mechanism.
