Description

The invention relates to the suspension of a glider to the hull, as well as to outboard motors for light boats and motor yachts.

Outboard water-jet outboard engine is known from technical literature (see book A.A. Pechatin. Motors of small and sports vessels. M .: DOSAAF, 1976, pp. 107-112), which has a clamp for mounting it on the boat transom or boats and suspension hinges and engine mounts to a clamp. Such a device does not allow to perform an outboard water-jet engine as an independent displacement unit, which has autonomous buoyancy and has its own control system.

Suspension of outboard motors on a transom is also known with the help of a clamp equipped with horizontal and vertical hinges (see book. E.G. Khorchordin. Outboard outboard motors. M., Handbook, 1998, pp. 277-276).

The closest technical solution for the present invention is the device for suspending the jet ski to a pleasure boat, having a cutout in the hull with guides in which the entire perimeter of the jet ski fender is fixed, after installation, in which the jet ski is fastened with a belt (See. “Boats and Yachts” N 3 / 1991, p. 27-28). This device (SHUTTLE CRAFT) has a special vessel to which a specially designed glider is suspended.

The specified device does not allow the use of an outboard engine on sports vessels of various types. Such an outboard engine has a complex structure, which does not allow moving the engine from one vessel to another by water and using it in a displacement mode for autonomous navigation.

The technical task for this invention is to simplify the design of the suspension of a water-jet engine, unification of its clamp with serial outboard motors, providing the engine with buoyancy and the possibility of autonomous navigation.

The specified problem is solved as follows. Two parallel vertical guides are fixedly fixed to the clamp mounted on the transom of the vessel, in the lower part of which a carriage is mounted that is movable in the vertical direction, moreover, the carriage has horizontal hinges with which it is connected with side clamps that are rigidly fixed to the bulkhead of the displacement hull with remote control, on which a remotely controlled water-jet engine is installed.

The invention is illustrated by the following drawings.

Figure 1, 2 and 3 are three projections of the outboard mounted on a multi-seat boat.

Figure 4 shows the spatial image of the outboard water-jet propulsion on a speed boat with a displacement of 2 tons

Figure 5 is a side view of the mounting system of the outboard water-jet engine to the side of the vessel.

Figure 6 shows the mounting system of an outboard water-jet engine in a spatial configuration.

The outboard jet engine is mounted on the transom (1) of a yacht or high-speed vessel (2) using a clamp (3). The clamp has a device traditional for outboard motors. The clamp has the form of a double bracket, which is mounted on top of the transom (1) of the vessel. At the ends (4) of the peripheral sections of the bracket, screw clamps (5) are installed for reliable fastening of the engine to the transom of the vessel. Two vertical guides (6) are attached to the clamp using hinges (7) and clamps (8), which allows you to adjust the position of the vertical guides relative to the plane of the transom of the vessel (and, therefore, relative to the waterline).

At the elongated ends (9), passed below the bracket (10) of the clamps (8), a movable carriage (11) is installed. Bottom on the vertical guides are limiters (12) for moving the carriage.

The stops can be installed using pins (13) at different distances from the lower ends of the vertical rails. And therefore ask. the necessary length of movement of the carriage up and down the guides.

Reinforced brackets (14) are made along the edges of the carriage on the opposite side to the transom, to which are mounted side clamps (16) using horizontal hinges (15). The clamps have grooves (17), which includes a fender bar (18) of the displacement body of a serial jet ski (19). For reliable fixation of side clamps on the fender bar, clamps have screw clamps (20). On the serial jet ski, in addition to the standard steering and engine controls, a remote control system is installed.

The steering shaft of the rudder (21) of the jet ski is connected to the helm (not shown) of the vessel (2) using a double flexible cable (22) (of the Bowden type).

Remote control of the jet ski engine is carried out using a cable mounted on the shell of a flexible cable (22), in a polyethylene casing of which an electric cable is laid (not shown).

The cable has three electrical wires, a starter lead wire, an engine ground wire and an engine stop wire.

The opposite ends of the cable (22) and the electric cable are connected to the engine control handle, with the engine stop button, which are installed on the instrument panel (not shown) of the vessel (1). The lower ends of the cable 22 are fixed on the steering shaft parallel to the tie rod steering nozzle. And the upper ends of the cable are laid on the helm coil. To disconnect the remote control of the jet ski (19) from the side of the vessel (1), plug connectors (23) and (24) are installed on the body of the jet ski. The connectors have a standard device for motorcycles and outboard motors with remote control.

Outboard water-jet engine operates as follows. Previously, on any serial jet ski (19), remote control elements are installed in parallel with manual control (steering wheel, engine control coin, engine start and stop buttons) and output to the plug connectors (23) and (24).

Previously, on the transom (1) of a yacht or a high-speed vessel (2), guides (6) with on-board side clamps (16) are fixedly mounted using a clamp (3).

A jet ski (19) is afloat down the ship transom. After that, the side clamps (16) are fixed on the hydro-motor's fender (18) in the bow of its hull, exposing the hull of the hydrocycle strictly along the longitudinal axis of the vertical guides (along the axis of the vessel (2)). In this case, the fender bar (18) is tightly inserted into the grooves (17) of the side clamps (16). Then the clamps are rigidly fixed on the fender bar with screw clamps (20).

Then, using the plug connectors (23) and (24), the flexible cables (21) and (22) of the remote control are connected to the onboard control system of the jet ski. The jet ski is filled with fuel and oil, and the outboard jet engine is ready for operation.

After the remote start of the jet ski engine, the ship departs from the coast and makes the movement in the usual way. The vessel circulates and moves in a straight line by controlling the helm installed in front of the driver's seat.

On the wave and with the differential of the vessel or jet ski, the jet ski rises or falls, swinging relative to the horizontal hinges 15, and also moves down or up along the vertical guides 9 at a distance l.

When making a maneuver, the steering nozzle of the remote water jet is deflected. Engine control is also provided.

When the vessel is parked in the roads, at a considerable distance from the berth, the jet ski is used for autonomous trips in the water area or to the berth. To do this, he undocks from the airborne clamps and remote control and makes a voyage offline with one or two operators on board.

The undocking and removal of the outboard water-jet engine is carried out in the reverse order indicated above.

Compared with the known devices, the proposed outboard engine has more power (80-240 hp). It can be installed on a ship without a crane.

When installed on a ship, it does not change the position of the center of gravity of the ship. A heavy outboard motor of the standard type (weight 150-320 kg) causes the trim of the vessel to the stern. For him, the vessel requires gas tanks, which occupy a significant place and have a lot of weight, which makes it difficult to move them manually.

The proposed outboard jet engine can be used as an independent vehicle.
