WATER FLOW ENERGY DAMPER Russian patent published in 2013 - IPC E02B8/06 

FIELD: construction.

SUBSTANCE: water flow energy damper comprises a supply channel 1 with a cantilever 2, installed in a niche 3 of a water cushion 4, and a baffle 7, made as curvilinear in the vertical plane. The baffle is made in the form of a lock, which has a shape of a sector in the cross section, which is attached with its top to the rear wall of the water cushion by means of a hinged joint with a horizontal axis of rotation 8. In the water cushion with the niche there is a bottom gallery 5 with a flushing hole 6. The cross section of the niche 3 corresponds to the cross section of the lock 7 in the idle position (lower position). At the side of the diverting channel 11 in the base and side vertical walls of the water cushion there are stops arranged, which interact with the lock in the operating position. One of the walls of the lock facing towards the niche of the water cushion is made as vertical, and the other one - as a web of roof-like shape with a canopy and a counterweight float of cylindrical shape in its ridge part. Additionally a stop is installed in the form of a float attached to the lock wall, which is installed as capable of contacting-jointing with the rear wall of the water cushion.

EFFECT: increased efficiency of energy damping by provision of automation of baffle actuation and improved functional capabilities of a device.
