Description

 There are known devices for excavating samples of vessels, consisting of a cylindrical vessel equipped with: mirrors with a thermometer inserted inside it. In the proposed device, the employee serves to close the hole in the bottom of the cylinder; the piston is located by pressing it to the bottom and is set to the required spring tension, abutting against the edge of the tube, moving inside the pipe attached to the device cover, and : on the cover; levers with a valve for air release. .

The drawing shows a vertical section of the device.,

The proposed vribo.r consists of an outer cylinder and an inner 2, in the lower part of the closed bottoms # and J, and on top of the lid 13. The bottoms are equipped with filters 6. The cylinder / protrudes beyond the outer bottom 4 and has a lower part in which the screw 5 is screwed.

The inner bottom 5 has in its center a tide with an orifice for a hydrostatic device consisting of a piston with a brush 10. The spiral spring Yx placed in the tube 5 is put on the latter The marked spring rests with its lower end

into the piston flange, -a upper-into the guide bushing. 11, on which the tube 12 is pressed, provided with a thread, with which it is screwed into the thread of the inside of the pipe 8. This pipe in its upper part has a flange that abuts against the lid and is fastened with the pressure sleeve 14, and at the bottom end is threading screwed internal bottom 5. A rubber 7 is laid between the external bottom 4 and the hydrostatic device, allowing the piston 10 to move and at the same time blocking the access of water to the hydrostatic device. Three holes were made in the lid / 5: inserts of a thermometer and pouring out, another for an airlock and a third for the upper end of a hydrostatic device, equipped with a bottom, on the outer circumference of which there is a cut on which the casing 15 is screwed on with an opening for the upper end of the piston rod . An elastic is inserted inside the casing (5), clamped by the sleeve 17 of the piston 18 and preventing the water from entering the hydrostatic device, allowing the shaft to rise. In the sleeve 17 is placed a piston 18 with a spring 19. The upper end of the piston rod 18 goes outside the tube

i-jqQ flHHHeit with a lever leading to an airlock 20.

A thermometer 25 is screwed into the housing of one of the openings of the cover 13.

The spring is compressed by a tubular key, on which the nano: .cf division in meters. In order to access the k tube / 2, it is necessary to unscrew the plug J5 with all the fixtures that are located in the Sch, but unscrew the lamb 22 and disconnect the levers .;

The proposed device operates as follows. Using a key, the spring of a hydrostatic device is set to the required depth from which it is desirable to take a water sample, and then the device is lowered into the water on the cable. When the desired depth is reached, water will go through the filter and the piston will start to flow into the device. Simultaneously with the raising of the piston, the rod / (rises upwards, through the rubber J6, onto the piston J8, rises upwards

and the last, 4epira-eyelet system, will open the air 4 into the 2ft stopper. When filled, the device rises. naru, shatas5 and equilibrium between}; the pressure of the water and the spring And the last ohlopnet device and the bottom and top, ie, close the filter and the air stopper

The subject matter of the invention.

A device for sampling liquids, consisting of a cylindrical vessel fitted with holes and a thermometer inserted inside it, which differs from the fact that the piston used to close the hole in the bottom of the cylinder is under the action of the receiving bottom and is set to the required voltage: springs a tube 8 that rests on the edge of the tube / 2, which is located inside the inner lid with appliance lid, and the brushes 70 of the piston passes through; inside the pipe (I am connected by means of installations of the cylinder cover with a valve from the valve); for air BfaiHjifCKa
