Description

 The invention relates to shipbuilding, in particular to nodes of high-speed boats.

 Known propulsion and steering device of the vessel (see USSR author's certificate N441196, class B 63 H 25/08 of 08/30/74), containing a water-jet propulsion and two shutters mounted on coaxial shafts, a control system.

 A disadvantage of the known device is the complexity of the design and, as a consequence of this, the low efficiency of the control complex.

 Closest to the proposed device is the propulsion and steering device of the vessel (see USSR Author's Certificate N977280, class B 63 H 25/46 of 12.30.82), containing a water-jet propulsion, a nozzle, a reverse gear and a control system mounted on it.

 The specified device has the same disadvantages as the previous device, which are more due to the complexity of the control system.

 The technical result that is achieved by using the proposed proposal is to create a simple and convenient design that allows you to effectively manage the vessel.

 The specified technical result is achieved by the fact that in the propulsion and steering device of the vessel, comprising a water-jet propulsion device, a nozzle, a reverse valve and a control system fixed to it, the nozzle is rotatable around a vertical axis, and the control system includes a control lever kinematically connected to the axes located longitudinally and transversely relative to the longitudinal axis of the vessel and respectively associated with the actuator of rotation of the nozzle and simultaneously with the actuator of rotation of the reverse gear and the engine control mechanism, the engine control mechanism is designed so that when the control lever is moved from the neutral position to the "forward" and "back" position, the engine speed increases. In addition, the axis of rotation of the nozzle and the reverse flap are mutually perpendicular in projection onto a vertical transverse plane.

 The essence of the proposal is illustrated in the drawing, which shows a diagram of the propulsion and steering device.

 The steering-steering complex of the boat 1 consists of an engine 2, a water-jet propulsion 3, and a lever 4 for controlling the movement of the boat. The jet propulsion device consists of a water intake 5, an impeller 6 with a shaft 7, a straightening device 8, a rotary nozzle 9, a reversing chamber 10 and a reversing shutter 11, the reversing chamber and the reversing shutter being located on the rotary nozzle.

 The rotary nozzle has the ability to rotate around its vertical axis 12. The reverse valve has the ability to rotate around its axis 13, perpendicular to the axis of the nozzle. The shaft of the engine 1 through a compensating clutch 14 is connected with the shaft of the jet propulsion. The lever 4 control the movement of the boat 1 has the ability to rotate around two mutually perpendicular axes 15 and 16, and one of the axes 15 is directed along the centerline of the boat.

 The device operates as follows.

 When the control lever is rotated around axis 15 in a direction perpendicular to the center line of the boat to the right or left, this movement is transmitted (mechanically, electrically, or hydraulically) through the drive mechanism 17 and execution mechanism 18 to the rotary nozzle 9 of the jet propulsion device 2, which, in its turn turns a stream of water; lateral force arises and, as a result, the boat maneuvers respectively to the right or left.

 When the control lever 4 is rotated around the axis 16 in the direction of the boat moving forward, this movement is transmitted (mechanically, electrically or hydraulically) through the drive mechanism 19 and the execution mechanism 20 to the reverse shutter 11, as well as through the engine speed control mechanism 21, the gear The movement to the reverse valve occurs immediately after the start of the movement of the control lever 4 forward, the valve 11 rises to the upper open position and does not interfere with the direct exit of the water jet from the nozzle 9, appearing thrust, the boat begins to move forward. With further movement of the control lever forward, a gradual increase in engine speed from minimum to maximum occurs, respectively, the speed of the boat in forward motion increases. When the control lever is rotated around axis 16 in the direction of the boat’s movement backwards, this movement is transmitted (mechanically, electrically, or hydraulically) through the drive mechanism 19 and execution mechanism 20 to the reverse shutter 11, as well as through the engine speed control mechanism 21, the motion transmission the reverse valve 11 occurs immediately after the start of the movement of the control lever 4 backward, the valve 11 lowers to the lower closed position and closes the reversing chamber 10 for direct exit of the water jet and nozzle. A jet of water leaves the reversing chamber through the exhaust window 22, a reverse jet thrust appears, the boat begins to move backward. With further movement of the control lever 4 backwards, a gradual increase in engine speed from minimum to maximum occurs, respectively, the speed of the boat in reverse increases. Thus, when the control lever 4 is rotated around the two axes 15 and 16, all boat systems responsible for its movement and maneuvering are controlled, and all systems in this connection are independent of each other.
