SU34829A1 - A device for determining the magnitude of the speed and direction of the vessel, crew, etc. - Google Patents

Description

The proposed device for determining the speed and direction of the vessel, crew, etc., consists of “paper tape, rewinding from one drum to another, proportional to the speed of the vessel, crew, etc., and located above the l, enty metal disk, and under the rail is a magnetic gun or a solenoid connected to an electrical circuit. The latter is periodically closed with a speed contact, in order to pierce the tape to indicate the position of the magnetic needle and at the same time move the tape in a discontinuous manner. For the mark of scopes, a pen is used, connected to the core of an electromagnet fed through the contact of a clock mechanism.

“To hell with FIG. 1 shows a top view of the device; FIG. 2 - side view; FIG. 3-stern part of the vessel with a turntable; FIG. 4 shows a device for rotating the coil winding tape.

The coil 7 (Figs. 1 and 2), rewinding the paper tape 2 from the coil 3, is rotated by the action of speed contacts from a turntable, wheel or anemometer, with the tape 2 moving along the rollers #. Above the cast 2, the disk 5 of a material conducting an electric current is fixedly fixed, and under the tape there is a magnetic arrow

(553)

(or solenoid). When the speed contact closes, the coil 7 turns the tape 2 moving, the current passes through the magnetic needle 6 and the disk 5 and the direction of the arrow is punched on the tape (dotted line in Fig. 1). The speed of movement of the tape is marked by a writing device 7 with the help of an electromagnet 5 operating: from the clock mechanism at regular intervals. Instead of writing device 7, penta can be punched with a current, which simplifies the construction. Accuracy can be very large depending on the length of the tape, the frequency of the contacts and the size of the magnetic needle. Instead of high-speed contacts, the coil 7 can be rotated by a clockwork, and the direction is punched by the high-speed contacts.

If the work is performed from the boat (Fig. 3), then the device can be simplified, namely: instead of rotating the coil 3 by an electromagnet, it rotates directly by the rod 5 (Fig. 4) with a worm and a JO under the action of the blades 7 / turntables enclosed in pipe (Fig. 3).

In the case of using a magnetic needle instead of a solenoid, the entire device must be suspended on a gimbal in order for the arrow to be horizontal while the vessel is moving or the axis of the arrow must be long.

.one

It should be firmly fastened with an arrow and strengthened in a ruby bearing and bearing, and the center of gravity of the arrow should be lower.

For larger steamers, arrow 6 may be replaced with a gyroscope.

The subject matter of the invention.
