FIELD: environmental control. SUBSTANCE: device relates to means of control over conditions of water objects, in particular to take sample of water of surface layer of water object from helicopters, floating craft and so on. When device to taken samples of liquid is submerged into examined water reservoir mobile float 7 floats up moving together with slider along rod 5 into extreme upper position and lifts shutting member 11 with the help of connecting rod 13, rocker 8 and sector 9 opening neck of intake chamber 12. Float 4 keeps device floating providing for sampling of water from preset depth. After taking of sample device is removed from water. As sampler come out of water mobile float 7 with slider 6 descends along longitudinal axis of rod 5 under action of gravity force and turns shutting member 11 with the aid of connecting rod 13, rocker 8 and sector 9 placing it on neck of intake chamber 12. After device is removed from water intake chamber 12 with water sample is taken out of cradle 1. EFFECT: reducing time for filling of vessel with sample of liquid while keeping its representivity. 1 dwg |
