EFFECT: increased efficiency when converting wave energy into hydroreactive energy.

The invention relates to a device for preobrazovaniya wave energy, in particular for the conversion of energy fluctuations of the vessel in hydro jet energy, including during storm conditions with simultaneous decrease of pitching auxiliary hydro jet device together with the device on which it is installed, for example a vessel.

Known auxiliary hydro jet device, in particular wave device containing a conduit, made in the form of two cameras with curved walls, and the output nozzle, each curved wall made in the form of shutters, hinged on horizontal axes can be rotated, and the length of each fold greater than the distance between adjacent axes (see inventor's certificate SU # 1749121, publ. 23.07.1992).

This device allows you to convert wave energy in hydro jet energy. However, the device contains a set can be rotated sash that can cause the device to fail when hit by foreign objects, which reduces the reliability of the device.

Closest to the invention to the technical essence and the achieved result is a subsidiary hydro jet device containing a conduit, made in the form of arranged symmetrically about its longitudinal OS the chambers with the inlet of the intake holes and horizontal curved walls, forming a narrowing in the course of the stream nozzle with outlet holes, perpendicular to the longitudinal axis of the conduit (see inventor's certificate SU # 982969, publ. 23.12.1982).

This device also allows you to convert wave energy in hydro jet energy. However, this device does not fully uses the energy of the waves, because it contains only two horizontally arranged relative to the longitudinal axis of the device input intake vents, which prevents the use of the energy incident at a small angle to the longitudinal axis of the device thread. As a consequence, the efficiency of the device is relatively small.

Task to be solved by the present invention is directed, is the use of all energy waves, regardless of the angle of crowding flow to the device along its longitudinal axis.

The technical result achieved by the invention is to increase the efficiency of energy conversion wolf in hydro jet energy.

This problem is solved and the technical result is achieved due to the fact that the auxiliary hydro jet device comprises a conduit, made in the form of arranged symmetrically about its longitudinal axis cameras with input water intake holes and horizontal in erachem section cameras curved walls, forming a narrowing in the course of the stream nozzle with outlet holes, perpendicular to the longitudinal axis of the conduit, the device contains one Central camera, two outer cameras, and at least two inner chambers, and the input of the intake openings of the outer chambers are arranged horizontally and oppositely facing each other, the input water intake holes in the inner chambers are located at an angle to the longitudinal axis and form the input of the intake holes of the outer chambers in vertical longitudinal section of an obtuse angle, and input the intake hole of the Central chamber is vertically perpendicular to the longitudinal axis of the conduit, and the vertical wall of the chambers formed by flat plates with the formation of rectangular cross section of the camera of the conduit, the outer horizontal wall of the outer chamber is made of a flat plate, and a horizontal curved wall of the internal chamber of the General one with an external camera, and the other with the Central chamber of the smoothly bent plates with convex relative to the longitudinal axis of the conduit section from the input water intake holes and concave relative to the longitudinal axis of the conduit section from the outlet nozzle.

During tests it was found that the combination of the horizontal, inclined and vertical cross-section located input intake holes located symmetrically relative to the longitudinal axis of the conduit device allows you to fully use the energy of the waves lapping on the device stream to convert it to a hydro jet energy. When installed on the vessel below the waterline, the device allows you to convert energy vertical and pitching of the ship in hydro jet energy, which in turn helps to stabilize the position of the vessel in heavy weather sailing and also to reduce rocking of the ship. In the keel and heave of the vessel, the device converts the energy of waves in hydro jet energy of a jet of water, which is at the front during the vessel is able to compensate some loss of speed of the ship in stormy conditions when the vessel against the waves, without increasing the speed of the screw in order to save fuel.

Figure 1 shows the design of the auxiliary hydro jet device is removed from one of the vertical walls of the chambers of hydrogen (path removed vertical wall is shown by a thin line).

Figure 2 shows a longitudinal section of the auxiliary hydro jet device.

Auxiliary hydro jet device comprises a conduit, made in the form of spaced, symmetry is but relative to its longitudinal axis (figure 2 shows how the axial line) of the camera 1, 2 and 3 with the input water intake holes 4, 5 and 6 and a horizontal cross-section of the chambers 1, 2, 3 curved walls 7, 8 and a flat outer wall 9 forming a tapering along the flow nozzles 10, 11 and 12 with the outlets 13, 14 and 15, perpendicular to the longitudinal axis of the conduit. The device contains one Central chamber 1 and at least two inner chamber 2 and two exterior camera 3. The number of internal chambers 2 can be increased. Water intake holes 6 outdoor cameras 3 are arranged horizontally and oppositely facing each other. Input intake hole 5 of the inner chambers 2 are arranged at an angle to the longitudinal axis and form the input water intake holes 6 outdoor cameras 3 in vertical longitudinal section of an obtuse angle α. Input the intake hole 4 of the Central chamber 1 is vertically perpendicular to the longitudinal axis of the conduit. The vertical wall 16 cameras 1, 2 and 3 are formed of flat plates with the formation of rectangular cross-section of the chambers 1, 2, 3 conduit. Horizontal curved walls 7 and 8 of the inner chamber 2 shared one with an external camera 3 and the other with the Central chamber 1 is made of smoothly curved plates with convex relative to the longitudinal axis of the conduit section from the input of the intake hole 5 and concave relative activities is but the longitudinal axis of the conduit section from the outlet 14 of the nozzle 11.

The inlet cross section of the chambers 1, 2 and 3 exceeds 13-20% of the area of the output cross-section of these chambers, respectively, 1, 2, and 3.

Angle α between input intake holes 6 and 5 the inner and outer chambers 3 and 2 in the longitudinal vertical plane of the cross section of these cameras is between 120° to 140°.

Input horizontal curvilinear walls 7 and 8 of the Central chamber 1 and the inner camera 2 is bent inside the chamber 1 with the formation of the interceptor.

Preferably the width of each of the cameras 1, 2 and 3 is from 2 to 4 from the height of the output section of the nozzle.

A device, usually installed below the waterline, in the area (or instead of) nasal Bulba, as well as in the aft part of the ship, on both sides of the deadwood, ahead of the screw and is oriented in the direction of motion of the vessel at the front of the fly.

Auxiliary hydro jet device may be made of the same material from which made the hull (steel, light alloy, fiberglass and the like), the same technology on the same hardware and the same composition of workers in the shipbuilding or ship repair companies.

The device is able to realize their potential fluctuations in the vessel in the direction of the vertical axis (up) and angular oscillations around a transverse axis (pitch is ACCA).

Energy conversion pitching in reactive focus is the result of the filling of the chambers 1, 2 and 3 of the device with water and push the water flows by the pressure of the incoming water through the chambers 1, 2 and 3 and the nozzles 10, 11 and 12 and output flows through the outlet openings 13, 14 and 15, respectively nozzles 10, 11 and 12 nozzles, with greater speed than when you log in the camera 1, 2 and 3, and in the opposite direction to the movement of the vessel at the front of the fly, creating a hydrodynamic focusing.

Essentially the device is fixed on the hull of the vessel, works as an additional hydro jet propulsion, disposing the vibration energy of the mass of the ship in the incident wave and giving the vessel an additional "stop" when moving in forward motion against the waves.

As an example, a more detailed description of the operation of the device according to the variant of oscillation of the vessel around the transverse axis (pitching) for the device installed in the area of the forward end of the vessel.

When driving forward end of the vessel onward and upward in the water column there is a movement mounted on a fore end of the vessel auxiliary hydro jet device forward and up. In the upper chamber 3 and 2 and in the Central chamber 1 is intensively supplied water. Partially water flows into the lower chambers 2 and 3.

When you log in the camera 1, 2 and 3 through the inlet of the intake openings 4, 5 and 6, the flow of the water under the pressure of the water, incident on the device from the input water intake holes 4, 5 and 6. The interceptors are executed on the walls 7 and 8 and forming the input of the transversal edge, holding the incoming water at the entrance of the Central chamber 1 and the inner camera 2, contribute to maintaining the pressure in the chamber 1.

The pressure of the incoming water provides the flow through the chambers 1, 2 and 3, which change in a given direction along the vessel flows of water, as well as creating conditions for passing the flow of water through a narrowing (confused) nozzles 10, 11 and 12 and support, due to compression, higher than at the entrance, the velocity of flow at the outlet of the nozzles 10, 11 and 12.

When the flow of water through the chamber 1, 2 and 3 energy pitching of the vessel in combination with the energy of an incident wave that advances flows and maintaining the pressure, and allows you to convert wave energy in hydro jet force horizontally, in the direction of travel of the vessel.

When driving forward end of the ship forward and down movement mounted on a fore end of the vessel auxiliary hydro jet device forward and down. In the Central chamber 1, and at the bottom of the inner and outer chambers 3 and 2 intensive water comes. Partially water enters the top of the inner and outer chambers 2 and 3. In the rest of the om happen the same processes of converting wave energy in hydro jet energy at the exit of the nozzles 10, 11 and 12 of the device.

The same way will work auxiliary hydro jet device when installed on the aft end of the ship.

In addition, auxiliary hydro jet device, campfire disturbing force, swinging ship, contribute to the stabilization of the position of the vessel and reduce pitching of the vessel, especially in stormy conditions.

The present invention can be used wherever there is a need to transform the wave energy in hydro jet energy, primarily in the shipbuilding industry.
