The helibucket is for loading, transporting and discharging water and products on fires and hangs from the loading hook of a helicopter. It is formed by a head which is linked to the helicopter, fastening cables, a cover with the foam tank, the floater and the mechanisms box, the base, which supports the weight and houses the discharge valve, the autonomous filling valves and the pump and a flexible canvas which joins the cover with the base. A motor with three reels for winding the cables controls the loading, unloading and folding. Hermetic closing is achieved since the surface of the bottom of the bucket is greater than that of the valve, and on taking weight, the helibucket moves downwards to the elastic limit of its cables, forcing the body of the valve against the valve gates thereby closing it. The helibucket is useful for extinguishing forest fires, increases to a great extent efficiency in firefighting as it transports 100% of the water it loads and enables the pilot to control how and how much water it discharges.
Helibucket for firefighting helicopters comprising a helibucket, wherein said helibucket transports any external load with helicopter and comprises a head that is attached directly to a helicopter, cables wherein said cables support the weight connected to said helicopter, a flexible canvas container wherein said canvas container holds water and a base with discharge valve wherein said discharge valve comprises a two-gate valve that is hinged along a central shaft wherein said gates open downward by means of said cables and are leaktight against the helibucket main body by means of a joint installed at the bottom of the base and the joints of the bridge and said two gates close upwards thanks to the pressure of the water moving the base downward and pressing the joints against the gates.
Helibucket for firefighting helicopters comprising helibucket and a cover, wherein said cover is closed along its perimeter and prevents a product inside said helibucket from spilling out either by splashing or by the suction of air during flight.
Helibucket for firefighting helicopters comprising helibucket and a cover, wherein said cover comprises a mechanism with an electromechanical actuator and a positioner that turns three reels with a motor and control cables wherein said control cables open and close a valve to divide a jet up into several discharges or to shape it as a fan or as a single, laminar and powerful jet.
Helibucket for firefighting helicopters comprising helibucket and a base, wherein said base comprises a fill pump with a filter and an electronic circuit comprising external sensors and internal sensors wherein said electronic circuit automatically connect and disconnect the pump until the programmed load is reached.
Helibucket for firefighting helicopters comprising a helibucket wherein said helibucket folds up vertically by means of several scissor-shaped hinges on its perimeter together with at least one belt that controls the canvas during a folding operation.
Helibucket for firefighting helicopters comprising a helibucket and a cover, wherein said cover comprises a foaming agent tank with a dosing pump and a float.
Helibucket for firefighting helicopters comprising a helibucket and a base, wherein said base comprises at least one autonomous fill valve.
