Description

Technical field

The utility model refers to the boat hydro-wheel used in shipbuilding for the creation of pleasure craft and sports craft. The boat is designed for short sailing.

BACKGROUND OF THE INVENTION

A two-seater hydraulic wheel comprising a housing, a water jet actuator with impellers, a reversible steering device (RCU) in the form of a rotary valve and a rudder, whose function is performed by a rotating nozzle of the actuator, a device for controlling movement the hydraulic wheel connected to the engine and the steering wheel, the seats of the driver and the passenger, one behind the other. The helmsman's seat is raised above the passenger's seat - a prototype (see Models Hydro Wheels Sea doo GTX RF company “Bombardier” http://www.magilan.ru)

The prototype mentioned has many disadvantages.

The high location of the center of gravity of the entire hydraulic wheel, together with the crew, in sharp maneuvers of the hydraulic wheel, leads to a large moment of overturning, that is, directly affecting its stability.

When the helmsman and the passenger are positioned one behind the other, they cannot transmit the controls to each other when driving. In addition, such control transmission is only possible on shore or in water when sailing is stopped.

The hydraulic wheel does not have the ability to achieve the dynamic braking effect often required in its sharp maneuvers. Even if this were possible, the high center of gravity, along with the passengers, would inevitably throw them off the wheel in the direction of translational motion.

The technical nature of the utility model

The utility of the utility model is to enhance the navigational qualities of the device by improving its stability in sharp maneuvers and by providing the ability to achieve abrupt dynamic braking using the reversing mode.

The technical effect of using the proposed solution consists in the fact that the small-sized two-seater speed hydro-wheel includes a housing, a water-jet actuator, a reversing-steering device in the form of a rotary valve and a steering-rotating nozzle, a device for controlling its motion connected to the engine and to the steering gear, seating positions of the helmsman and passenger, located on both sides in diametrically spaced planes (DRs) of the hull of each boat, and having as low as possible relative to the waterline of the hydrofoil. The motion control device is located between said seating positions and is predominantly in the form of a joystick, kinematically coupled to the rudder and a control system, kinematically connecting the engine control and the reversing device. Said control system is designed in such a way that when the lever is tilted from the initial position to the "forward" position, the reversing device is brought into "forward travel" mode, and the engine speed increases in proportion to the displacement of the joystick, and at the lever tilting from the starting position to the "reverse" position, the reversing device is reversed accordingly, and the engine speed rises in proportion to the inclination of the joystick lever.

The joystick lever is connected to the handlebar in such a way that when the joystick lever is tilted to one side, the hydro-wheel boat is pointed to the same side, and vice versa.

Moreover, the hull of the hydro-wheel boat, in the area of the seats of the helmsman and the passenger, has secured edges.

The positioning of the seating positions of the helmsman and the passenger at the edges on both sides of the DR of the hull of the boat, at a level close to the waterline, allows the center of gravity of the device to be reduced as close as possible to the waterline, which gives great stability at finding sailors

1044 W is the cruise ship passenger and maneuvering safety.

The positioning control of the propulsion mechanism of the boat of the hydro-wheel between the seats of the helmsman and the passenger enables the steering to be carried out by both one and the other person, as well as the helmsman can be positioned to control both the right, so with his left hand (if he is left-handed).

The motion control device, predominantly in the form of a joystick, kinematically coupled simultaneously to the rudder and the engine control system and the reversing device, enables the active and dynamic control of the hydrofoil even by an unprepared person.

The control system of the reversing device and the engine when, when the reversing device is moved to the "forward or reverse" position, the engine speed increases, it allows sharp maneuvers to be made when moving the hydro-wheel and uses the principle dynamic braking, provides a significant increase in braking efficiency, no need to stop the hydrofoil.

Due to the presence of a lever, all controls via kinematic coupling with the rudder, motor and reversing device ensure all the mentioned maneuvers and movements of the boat.

Description of the attached figures

The essence of the utility model is explained by the figures where:

- Figure 1 is a side view of a hydrofoil;

- Figure 2 - Top view.

The small, speed double-seater hydrofoil has a housing 1, inside which are located at the edges on both sides of the diametrical plane 2 seats for the driver and passenger, water jet actuator 4, actuator 5, RCU 6, lever joystick 7 the movement of a cathehydrocycle.

The water jet actuator 4 includes a suction channel 8 and a rotating nozzle 9. The RCT includes a backward rotating valve 10 and a handlebar, the function of which is performed by the rotating nozzle 9 of the water jet driving mechanism 4.

The reversible valve 10 is able to rotate about its horizontal axis 11.

The joystick control lever 7 is located between the driver's and passenger's seats 3 and is kinematically coupled to the rudder and via the engine control system and the reversing device (not shown in the drawings) and is coupled to the latter. tilts downward and transversely to the hydro-wheel in a diametrical plane.

An example of a utility model

The device works as follows. The starter man tilts the joystick lever to the forward position, using a kinematically coupled control system, with the reversing device of the water jet actuator moving to the forward position and the engine begins to increase speed its in proportion to the inclination of the dovetail. To move the hydrofoil backwards, the joystick lever tilts in the "reverse" position, in which the reversing device moves to the reverse position, and the engine begins to increase its speed in proportion to the inclination of the joystick lever.

Maneuvering of the hydro-wheel is carried out at some position of the lever, when the hydro-wheel moves forward or backward. When the lever is tilted to the right or left, the hydrofoil boat maneuvers to the right or left, regardless of its forward or backward direction. Just as the joystick control lever is located between the helmsman and the passenger and is the sole means of controlling the hydrofoil, each of them can take control in the driving process without risking a dangerous situation in the water.

At high speeds, a really sharp maneuver on a hydrofoil can be achieved and thanks to a companion4

1044 Ul kata and the location of its center of gravity as low as possible near the water line, will maintain its stability and avoid the risk of people overturning.

To perform a rocker-boat maneuver by using the principle of hydrodynamic braking, the joystick lever sharply moves from the "forward" position to the "reverse" position. In this case, the engine speed drops for a short period of time, the reversing device switches to the "reverse" position, after which the engine speed increases. The reversing device begins to operate in inverted mode, but the hydrofoil boat still retains its progressive motion and at that moment a reversing force is generated in the actuator. In the next moment, the hydrofoil boat sharply decreases its speed and goes into displacement mode of movement (immersed in the water as much as possible) and consequently increases the resistance of its hull and accelerates its braking even more.

Thanks to this, the braking efficiency is increased many times over. When the hydrofoil boat reaches zero speed, the joystick lever switches to neutral and the hydrofoil stops.

The lower location of the center of gravity of the hydrofoil with the crew permits such braking to be carried out without risk to the life of the crew.

To move backwards, the joystick lever moves to the "reverse" position and the boat, which has stopped, begins to move in this direction.
