SU10245A1 - Depth gage - Google Patents

Description

In the proposed depth gauge, in order to achieve continuity of readings, a water pressure gauge is used, equipped with an elastic tube, the end of which is connected to the core rolling along the bottom of the river.

In FIG. 1 depicts a depth gauge detail; FIG. 2- different positions of the subsea part of the depth meter.

To the cable 1, equipped with core 2, with the help of the clips 3 is attached a waterproof elastic tube 4, ending at the bottom of the river with a tube 5 with a safety net; the other end 8 of the tube 4 enters the upper part of the vessel 6, which is located in the wheelhouse. The lonometric tube 7 in its upper part is equipped with a corresponding scale, while the lower part is lowered almost to the bottom of the vessel 6, partially filled with some fluorescent liquid, illuminated from below with an electric lamp 9 fitted with a current-regulating rheostat 10. For the purpose of shading the effect of the liquid column at

tube 7, the side surface of the vessel 6 is coated with black paint.

The action of the depth gauge is as follows: following the movement of the vessel, the core 2 rises and falls according to the change in the bottom profile, due to which under water is a larger, then a smaller portion of tube 4, and the air from the upper part of the vessel is then sucked in, then again tube 7, the height of the column of liquid, marking on the scale of the corresponding passable depth.

The subject of the patent.

A depth gauge characterized by the use of a waterproof elastic tube 4, one end of which enters a closed vessel 6 with a manometric tube 7 located in the wheelhouse, and the other end is lowered into the water and supported by a cable 1 with a bottom 2 running along the bottom.
