Description

There are devices for measuring the topography of the bottom from a moving vessel using a dragging along the bottom of the lot using graphical recording of measurement results.

In the proposed device, in order to give the drum with a registration tape a rotational speed proportional to the speed of the vessel, a spring-balanced wind vane is strengthened on board the vessel, affecting the speed of rotation of the drum by re-passing the belt drive along two conical pulleys, one of which is connected to the drum and the other -with an electric motor.

In the schematic drawing of FIG. 1 is a side view of the device; FIG. 2 is a front view thereof and FIG. 3 - tape recording the bottom relief.

The drum / with a paper tape worn on it to record the bottom relief receives rotation from the electric motor 2 through a 3-4 gear train and two conical jaws 5 and 6 joined by a pass 7 of the belt drive. Pass 7 can be moved along the conical shkiki 5 and b with the help of a brush 8, immersed with a spring P, sandwiched between a washer W placed on a brush 8 and a stand //. The other end of the rod 8 is provided with a roller 12 supported in a cam / 5, mounted on

reinforced aboard J4 of the vessel and spring-loaded 75 shchtok / b with wind vane 77.

A cable / P with a lot 20 attached to it is hung to the box J8 of the described device. The cable passes through a tube 27 attached to a rod 22 passing through a finger 23 fixed on a cam 24 supported by a stand 25. In the side face of the cam 24, abut the roller 26 fixed on the end of the spring 28 supplied with the rod 28, on the other end of which a pencil 29 is fixed, which serves to record the bottom rail on the paper tape of the drum 7.

When the vessel is moving, drag the lot along the bottom of the water basin, and depending on its depth, the cable 19, deflected at a certain angle, rotates the tube 27 and with it the finger 23 and the cam 24. Together with these rollers 28 with the roller supported in the cam 24 26 is displaced longitudinally, so that the pencil 2P draws on a paper tape, put on the drum 7 rotated by the electric motor 2, a curved line corresponding to the bottom relief.

The paper tape (Fig. 3) is graphed by cells, with the depths indicated in one direction and the distance covered by the vessel in the other direction.

To avoid distortion of the relief

the speed of rotation of the drum / should be proportional to the speed of the vessel. This is achieved because, depending on this speed, the weather vane / 7 is deflected by a greater or lesser angle under water pressure, and pass 7 moves along conic shafts 5 ib, whereby at a uniform speed of rotation of electric motor 2 the speed of rotation of the drum / is different the vessel.

The subject matter of the invention.

A device for graphic registration from the bottom relief vessel using

dragging along the bottom of the lot, causing the writing device to move when the inclination angle of the supporting cable changes, characterized by the use of a wind vane / 7 fixed on board the vessel and balanced by a spring, which serves to give the drum 7 with a tape to record the rotation speed proportional to the speed of the vessel the pass 7 of the coupling of the drum 7 with the electric motor 2 of a conventional belt drive with conical pulleys, when the cam 13 is driven by the wind vane 17, under the action of a spring stock 8. to the author's certificate of I.
