Abstract
Apparatus (10) is defined for regulating the level of liquid on a first side of a barrier (12) with respect to a moveable level of liquid on a second side of the barrier. The apparatus includes an inlet conduit (30) for positioning on the second side of the barrier and having an inlet (38) that is arranged for moving up and down with the liquid level, and an outlet conduit (16) for positioning on the first side of the barrier (12) and in liquid communication with the inlet conduit (30) across the barrier. The outlet conduit has an outlet (22) that can be located at a predetermined liquid level at the first side.
Claims18
Apparatus for regulating the level of liquid on a first side of a barrier with respect to a moveable level of liquid on a second side of the barrier, including:
- an inlet conduit for positioning on the second side and having an inlet that is arranged for moving up and down with the liquid on that side and;
- an outlet conduit for positioning on the first side of the barrier and in liquid communication with the inlet conduit across the barrier, the outlet conduit having an outlet that can be located at a predetermined liquid level on the first side.
Apparatus as claimed in any one of the preceding claims wherein the inlet conduit further includes a float adjustably arranged thereon for facilitating the up and down movement of the inlet with the moveable liquid level.
Apparatus as claimed in any one of the preceding claims wherein the inlet conduit moves up and down between a pair of guide rods arranged on and extending out from the barrier on the second side.
Apparatus as claimed in any one of the preceding claims wherein the inlet is defined as a downwardly curved elbow formation positioned at the end of the inlet conduit.
Apparatus as claimed in any one of the preceding claims wherein the inlet conduit includes a non-return valve that is arranged to allow liquid to flow from the inlet conduit to the outlet conduit only.
Apparatus as claimed in any one of the preceding claims wherein the outlet conduit is fixed but the outlet thereof is height adjustable by positioning one or more conduit extension pieces on the end of the outlet.
Apparatus as claimed in any one of the preceding claims wherein the outlet is surrounded by a mesh filter, or is fitted with a mesh filter cap, to prevent the ingress of debris into the conduit system and thus to prevent debris transfer between liquid bodies on opposite sides of the gate.
Apparatus as claimed in any one of the preceding claims wherein the inlet is surrounded by a mesh filter, or is fitted with a mesh filter cap, to prevent the ingress of debris into the conduit system and thus to prevent debris transfer between liquid bodies on opposite sides of the gate.
Apparatus as claimed in any one of the preceding claims wherein the barrier is a floodgate.
Apparatus as claimed in any one of the preceding claims wherein the apparatus is used in conjunction with a barrier between a tidal (moveable) liquid body and a fixed height liquid body.
Apparatus for regulating the level of liquid on a first side of a barrier with respect to a moveable level of liquid on a second side of the barrier substantially as herein described with reference to the accompanying drawings.
