Description

The still existing batometers are based on the principle of long or instantaneous filling. The filling of the bathometers based on the first principle is performed at reduced speeds, which, under the conditions of the bottom layer, leads to a significant decrease in the number of nano-nos-6nos. and give an exaggerated sample.

The proposed bathometer eliminates these disadvantages, since its filling is at a speed that corresponds to domestic speeds. In addition, the shape of the bathometer is well streamlined and the tube through which the filling takes place does not allow us to remove the turbidity of the bottom layer in the These samples, and the tube and the discharge from the air-meter are fitted with a valve controlled by a water x {) luger.

The filling is performed under a pressure that automatically changes the nptf change in domestic speeds. - The drawing of FIG. 1 shows a pro- sectional section of the bathometer; FIG. 2 is a plan and FIG. 3 front view of the bathometer. ,

    A bathometer is a metal vessel 1 with a tail 2 of a well streamlined shape. Two tubes 3 and 4 are located at the front. One of the tubes 3, mounted horizontally, serves to take samples of fiaHocoB, and the other 4 is directed upward and serves to release air from the batometer throughout its filling. This last tube has a rubber insert, which, in the presence of a special clamp 5, makes it possible to release air from the vessel at the required moment and to fill the bathometer. The water inlet speed is regulated by raising the end of the tube 6. This lifting is carried out by rotating the tube around axis 7, which is achieved by using a special water vane 8, two plates of which are mounted on the same axis 7. Previously the instrument calibrates:, t. That is, the rate of its filling is determined at different depths of the river and at different speeds of the river. In this case, the weight and area of the blades of the flyuerch, the size of the inlet opening and the head are selected so that the entrance speed is close to the natural one. When working with the batometer in this way, the appropriate rate of water entry will be achieved. Before lowering the appliance

The water outlet must be closed; . this is achieved with the construction of the clamp 5. The opening and closing of the clamp is made during the observation period by tensioning and loosening the lifting cable 9, in which the tension of the cable leads to closing and the opening of the clamp. The weakening of the cable occurs at the moment when the device touches the bottom, which is facilitated by current loads 10. In the event that a batometer is used for samples of suspended sediment not from the bottom, but at certain points, they can be opened using a suspension gauge on two cables. In this case, the tension of one cable leads to the closing, and the tension of the other - opening the device. Capacity of the bathometer is from 1 to 3 liters. The attached pr6b diagram is shown in accordance with the dimensions it should have

in case the capacity of the bottle is 3 liters; with a capacity of 1 liter, all dispensers must be reduced accordingly.

For constructive reasons, it turned out to be expedient to provide additional weights on top of the vessel — front cargo AND and rear cargo 12; The hinge 13 is twisted to rotate the weights 10 connected by a bar 14. The rotation of these weights is associated with the closing and opening of the clip 5.

The subject matter of the invention.

Batometer with the use of a vessel in the form of a crate; provided with a receiving tube and a tube for discharging air from the vessel / characterized in that the tubes; Channels 4, 6 for air are fitted with a valve 7, controlled by a water vane 8.
