Description

The present invention relates to the type of ship propulsion located on the same shaft from the two sides of the vessel and supplied with a half-open casing, pivoting, with the aim of changing the direction of the vessel's travel.

In FIG. 1 denotes the side view of the impeller; FIG. 2 is a diametrical section; FIG. 3-16 - options and details of the device.

Wheel A (Figs. 1 and 2) with blades C is enclosed in a stationary half-open casing D, with a hole OO. The casing is mounted on a sleeve that can be rotated in bearings d (located inside the vessel) by means of gear C. Inside the casing D, there is a cylindrical damper xx (Figs. 1, 2, 3), which prevents the water wheel from turning the hole of the ROE into the right part of the wheel Q, which is arranged to save work due to the resulting reduction of the harmful space while reducing the rotation of the water in the right parts of the wheel. The water enters the wheel through the hole of the RO (Figs. 1, 2, 8), rotates in the direction of the arrow (Fig. 1) the blades and, under the action of reactive forces, presses the left side of the casing in the direction of movement of the vessel, being thrown to the right top of the casing. In order to reverse the vessel, the casing D is rotated by its gears 180.

FIG. 4, 5 shows the same device, where instead of opening 00. in the casing, a suction inlet ZZ is made, through which water enters the wheel only to its left side, does not fall into the right one. The valve xx has a cylindrical shape. To avoid a vacuum, there is a tube i (Fig. 4) sucking in air. Water cannot enter the wheel on the right side, so

as ejected by the centrifugal force. On .fig, 6 shows the deviceTBjD in g kot0ro; th wheel has ko-. zh - / P-with the channel of the AAG located; around its circumference; the wheel A enters the water through the hole OO, as in FIG. 2 and 3, and the entrance through the opening of the TP into the channel of the LG, by the action of i centrifugal force, presses the wall in the direction of movement of the vessel. On ; FIG. Figure 8 shows the same device, but without the K channel. The propulsion device is installed slightly above the waterline (Fig. 7).

FIG. 9, 10, 13 and 16 shows an I device in which the wheel A is placed horizontally at the bottom of the vessel at the stern, at which water enters the wheel through the opening 00, and is ejected through the opening OO. The device p serves for the return stroke of the vessel and consists of a pp box (Fig. 16) in which the yy axis turns (Figs. 11, 14, 15) and a rectangular shield d, blocking for the backward movement the outlet opening of the box, tp (Fig. 9 and 16), causing the water to flow back in the direction of the arrow and the vessel is reversed. Shield d can also serve as a wheel.

FIG. 13 shows the installation of two wheels with a box p having a circular shape, with a shield d in the form of a disk.

FIG. 11 and 12, the same p-box device is shown to achieve the vessel's reverse travel with an ordinary screw. The box consists of two concentric rings pp and pp placed behind the screw v, at which the screw rotates outside the ring pp, the disk d rotates on the axis g, closing the hole tp of the box pp at its position perpendicular to the movement; The vessel’s water, which is thrown off by a screw, will go back through the annular hole p p in the direction of the arrow, causing the vessel to reverse.

FIG. 16 and 17 shows the same npkf6op (cut and plan) with movable rings K and K, which are moved along the axis inside the fixed ring p, by means of cranks: sp t, fixed on the axis / t of the disk d and the connecting rod /; To return the vessel, the disk d is handle / placed perpendicular to the movement of the vessel, at the same time the rings / SLs are moved and the ring K slides over the screw, causing the water to flow back in the direction of the arrow.

The subject of the patent.

1.Reactive vane ship propulsion with pivoting half-open casings to obtain the vessel's reverse travel, characterized by the use of two wheels A mounted on a common horizontal shaft with blades C (Fig. 1-3), rotated in rotary covers D, equipped with a suction round hole OO in the center wheels, an outlet in the part Q of the wheel, a semi-cylindrical valve XX and a tube f through which air is sucked into the part Q of the wheel.

2. Alteration of a mover described in paragraph 1, characterized in that the intake hole of an OO is replaced by a slot ZZ (Fig. 4 and 5), and the damper xx has a cylindrical shape.

3. Alteration of the mover described in paragraph 1, characterized in that the casing D has a narrow discharge port tp (Fig. 8).

4. Variation of the mover described in section 3, characterized by the use of a pipe / C attached to the casing D and including the opening of the TP (Fig. 6).

5. Videoproduction of the drive described in paragraph 1, characterized by the use of one (Fig. 1 and 2) or two (Fig. 5) wheels A mounted on vertical shafts, the water being sucked through the hole of the RO from the bottom of the vessel and thrown out through the hole O Oh in the feed.

6. In the mover described in p. 5, the use of a device for the vessel's reverse travel, consisting of a TP box, dressed with a gap on the outlet port p and equipped with a butterfly valve d (Fig. 9, 10, 13 and 16).

7. Modification of the fixture described in paragraph b.

The back of the vessel, characterized in that in the case of using a propeller (fig. 11 and 12), the pipe K (fig. 14) is rigidly connected with the pipe moving inside the pipe p using the crankshaft / ;, and the connecting rod / pipe K.
