Description

one

FIELD OF THE INVENTION The invention relates to the field of shipbuilding and is related to repair, steering and steering equipment.

The reverse steering wheel is known: the devices are judged with a water-jet propulsion unit, containing a discharge pipe, water-flow channels for reverse, and reagent-controlled nozzles and bucket-shaped deflectors controlled by means of bullets.

The aim of the invention is to reduce hydraulic losses and improve ship maneuverability.

To do this, the water-flowing back channels are made with louses communicating with the roar-steering box mounted in the T1 of the vessel and connected to the propulsion pipe, and the deflectors are installed pivotally in the back-holes of the water-flowing back channels. The reagent nozzle is located in front of the deflectors.

FIG. 1, 2 shows the device in two projections.

The reverse steering device consists of a rotary nozzle L rotating on a bullet 2, two turning each on its own bullet and 4 deflectors 5 and 5, reversing the steering short 7 in which the specified rotary deflectors and turning nozzle /, two water-flow reverse channels 5 are mounted and 5 and pressure pipe 10.

The rotary nozzle / is made in the form of a through P1 solid-body truncated cone fixed to the bullet 2 and having the ability to rotate in the horizontal plane. The puller of the rotary nozzle is made split and does not pass through the cavity of the rotary nozzle /. The 5, 4 bullers are also made split, not passing through the cavities of the deflectors 5 and 6.

The rotary deflectors 5 and 6 are buckets turning on vertical axes x-bullets, the guiding walls of which are made curved along a curve (in this case, but the circumference).

The reverse steering box 7 is the part of the ship's transom in which the rotary nozzle / and the rotary deflectors 5 and 5 are mounted on their boilers. Water channels reverse 8 n 9

are made in the form of pipes through which the jet of water is diverted at the back course.

When the vessel is moving with a clean forward stroke, the nozzle is in the DP,

The deflectors 5 and 6 are removed in Vichy boxes 7 and do not prevent the projectile from ejecting water. The forward turn of the ship is carried out by deflecting the jet of water from the propulsion nozzle to the left or right side.

When the vessel gets out of its niches. Turn the deflectors 5 and b, which change the direction of the outflow of the jet of a dvigatel, the vessel receives a clean back and then two streams and send them to the water reed canals 8 and P.

The reversal is made as a result of the deflection of the jet, the propeller of the rotating nozzle / on (Right or left side With fully extended deflectors 5 and b.

Subject invention

Reversing steering gear of a vessel with a jet propulsion vessel, containing a naddetitelny pipe, water-flowing reversing canal, and controlled by means of pulleys, a jet nozzle and a bucket about different deflectors, characterized in that, in order to reduce hydraulic losses and increase manure, The ship’s water supply channels are made with recesses communicating with (reversing-steering box mounted in the vessel’s transom and connected to the propulsion thrust pipe, and the deflectors are rotatable in destitute water-flow channels reverse, with a reactive Oonlo located in front of the deflectors.
