<p>The device can be used in oceanology and in monitoring sea investigations, in particular in hydrobiology. By it zoobenton organisms are taken from a wide range of types of ground and facilities are open for precision quantitative selection, as well as for controlling the sample-taking process. The device consists of a bag (1) of a synthetic net having specified size of the eyes, fitted by a bracket (2) to a body with a bayonet endpiece (4) in which a valve (3) is mounted having a handle outside it, coupled to a respective endpiece (5) of an intake pipe (6), in the lower end of which a second stage (7) of a breathing diving automatic device is externally fitted, the outlet for medium-size pressure is connected by a hose to the first stage (12) of the breathing automatic unit, mounted on the valve of a diving bottle (13), the other outlet of the second stage (7) being connected by a flexible pipe (10) to mixer (9), mounted at the lower end of pipe (6) the surface of which, in the zone of the mixer (9), is perforated. On its external wall a plate is fitted with a handle (8) mounted to it with a screw resting on the bypass of the second stage (7). To the lower end of pipe (6) and mixer (9) a flexible pipe (11) is fitted with an endpiece, serving for the intake of the sample, limited by a frame (14), which has been stuck in the ground in advance. 1 claim, 1 figure</p> |
