SU21712A1 - Device for preventing the machine from accelerating when the ship's propeller leaves the water - Google Patents

Description

In the proposed device, to protect the machine from acceleration when the ship's propeller leaves the water, in order to maintain a constant load of the machine, it is used to act on the servo contact wrench articulated with the key using a chain and transfer a float floating on the surface of the water the bell. The bell is located in the stern of the vessel in such a way that its average cross-section coincides with the level of the extreme upper edge of the propeller, and the lower part of the bell bears on itself pipes for in / out and out of water.

In the drawing of FIG. 1 schematically depicts a vertical section of a bell with an indication of the articulation of the float and the servo key; FIG. 2 is a view along arrow A in FIG. one.

The adaptation is as follows. In the stern of the vessel, the bell is positioned (Fig. 1) so that its average section AB coincides with the level of the extreme upper edge of the propeller, which bell in its lower part for water inlet and outlet is provided with nozzles 2 and has, in addition, elastic gaskets 4, 4. On the surface of the water in the bell is placed a float b, which, by means of a chain 7. slung over blocks 8, and a lever 9

(Fig. 2} articulates with the contact key 10 of the servomotor. At the end of the chain 7 there is a counterweight 12.

In the normal position of the propeller, the bell 1 is filled with water, and the float 6 is pressed tightly against the gaskets 4, 4 at the top of the bell. When the water gets stern from the water, the level of the float in the presence of nozzles 2 also decreases, as a result of which the float b goes down and there is no chain 7 behind it rotating the blocks 8 - The lever 9 on the axis of the larger block 8 comes into contact with the key 10 servomotor, which circumstance allows to have the necessary adjustment. From the initial installation of the lever 9 depends on the moment of the beginning of its contact with the key 10, and consequently, the mode of operation of the machine, which will be obtained when the float reaches the level of -4-B, when the screw starts to come out of the water.

Bell 1 can also be installed on the stern of the vessel on board, in which case the wall of the bell adjacent to the casing has a curvature of the latter, and the opposite is a flowing form, at which location the nozzles 2 are replaced with one bottom opening for water inlet and outlet.

The subject matter of the invention.
