Abstract:
A watering device includes a sprinkler member having a plurality of sprinkling orifices configured to distribute a fluid over a coverage area during a sprinkling mode and at least one setup orifice configured to direct a stream of the fluid substantially along a boundary of the coverage area during a setup mode. A valve member operates between a first position to direct a supply of the fluid to the setup orifice during the setup mode and a second position to direct a supply of the fluid to the sprinkling orifices during the sprinkling mode.
Abstract:
A self-powered foam (e.g. compressed-air foam (CAF) ) distributor has a rotor mechanism with impingement surfaces against which foam impinges to rotate the rotor. The rotor is mounted on an inlet shaft geared to an output shaft. A rotary outlet is mounted to the output shaft so that foam entering the distributor rotates the rotary outlet, which in turn projects foam around in a circular sweep. The rotary outlet can rotate over a full 360 degrees, providing superior coverage for a large floor space, such as in hangars or warehouses, with less water and concentrate than in unfoamed conventional systems. Having a compact vertical profile this versatile distributor can be installed in a floor trench of a hangar or on a wall or ceiling. Since all rotational energy is harnessed from the pressure of the foam itself, no external energy source is required to power the distributor.
Abstract:
Für eine Beregnungsanordnung mit einem oszillierend geschwenkten Regnerkopf, insbesondere einen Versenkregner, wird eine Verstelleinrichtung beschrieben, mittels welcher beide Sektorgrenzen des von einem abgegebenen Wasserstrahl überstrichenen Beregnungssektors unabhängig voneinander und ohne Öffnen des Regners veränderlich einstellbar sind.
Abstract:
A sprinkler includes an outer housing (12) having a lower end connectable to a source of pressurized water and a riser (14) that is vertically reciprocable within the outer housing (12) between extended and retracted positions when the source of pressurized water is turned ON and OFF. A nozzle (17) is mounted at an upper end of the riser (14) for rotation about a vertical axis. A Pelton turbine (20) is mounted inside the riser for rotation about a horizontal axis, as distinguished from a vertical axis. A drive mechanism connects the turbine (20) to the nozzle (17) so that when the source of pressurized water is turned ON the resulting rotation of the turbine (20) by the pressurized water will rotate the nozzle (17). The turbine (20) as well as a gear train reduction and a bevel gear reversing mechanism are assembled inside a self-contained clam-shell drive subassembly before being inserted into the riser (14).
Abstract:
A rotary sprinkler is provided herein capable of providing automatic matched precipitation to arc adjustments. Sprinklers herein includes an arc setting assembly or mechanism that enables reversing, part-circle operation or, in some cases, full-circle operation with automatic matched precipitation coupled to the arc setting mechanism operable to effect automatic matched precipitation based on adjustments to the arc of rotation of the nozzle turret.
Abstract:
The present invention relates to equipment for improving the efficiency of solar photovoltaic equipment. In the equipment for improving the efficiency of solar photovoltaic equipment according to the present invention, solar photovoltaic equipment comprising a plurality of solar modules is divided into a plurality of sectors, and cooling water is sprayed separately for each sector, the cooling water being sprayed while a cooling-water-spraying means rotates backwards and forwards, thereby making more efficient use of water resources but nevertheless also making it possible to improve cooling and cleaning efficiency by spraying an impinging jet of cooling water with adequate water pressure.
