The invention relates to a wave power plant containing at least one float or multiple related floats.

In an alternative embodiment, a wave power plant comprises anchored underwater blades.

In the document US-4266143 disclosed wave power plant that converts the floating roll tank from one side to the other during the rotation of two heavy gravity wheels rotating in opposite directions. The floating tank is symmetric, and gravity wheels placed in opposite phases to ensure alternate roll to one side.

On this wave power plants and other known wave power plants adversely affects the uneven motion of the waves, the size of which is variable. Efficient transformation of this reciprocating motion in continuous rotation proved elusive.

The present invention is to develop a new wave power plant, which eliminated the disadvantages indicated above by converting the reciprocating motion of the waves directly in continuous rotation.

This task is solved in accordance with the present invention on the basis of the distinctive signs provided in paragraph 1 of the applied formula. An alternative is Ariant of carrying out the invention is presented in paragraph 14 of the formula. The engagement of the blade 14 of the formulas of the invention provide the possibility of increasing the number of selected energy by increasing the circular motion of the wave power plant by means of currents of different forces inside waves. Preferred embodiments of the invention are disclosed in dependent claims.

The basic idea of the invention is based on the use of shape and/or location of floats to align the axis associated with them, in a circular motion, which directly can be obtained for continuous rotation by using a spinner or the corner of the shaft.

Hereinafter the invention is described in relation to exemplary embodiments with reference to the accompanying drawings.

1 schematically shows a wave power plant according to one preferred variant implementation of the invention.

2 and 3 show variants of the wave power plant, shown in figure 1, in which the corresponding effect achieved by different designs of floats.

Figure 4 shows the use of the arc-shaped float, similar to that shown in figure 3, provided another device for power.

5, 6 and 7 show variants of execution, in which circular motion is provided not design a single float, as in the variants of execution, shown in figure 1-4, and whoopass the m location separate floats.

Fig shows another variant embodiment of the invention by the use of blades which are anchored at a selected angle below the water surface and which does not revolve around any shaft, and sway back and forth and thus lead axis 10, is attached to the holder 14, the blades in a circular motion, which is used to create a rotation.

Fig.9 shows an exemplary embodiment of elements, by means of which rotary motion can be converted into rotation.

Figure 10 shows a view of another exemplary variant the execution of the wave power plant according to the invention with a partial cut.

Common to the embodiments shown in figures 1 and 4 is that the float 1 in them designed asymmetrically relative to the direction of wave propagation, so that the float 1 performs a circular movement in response to the buoyancy effect of the sequence of waves propagating in the mentioned direction. Figure 1-4 the direction of the crests of the waves shows double lines. The float 1 is anchored long cables 8 in a predetermined angular position (usually longitudinal) relative to the direction of movement of the waves. Zakalivanie carried out in such a way that the float 1 retains its angular position despite changing the direction of the waves. In the cases, shown in figures 1, 3 and 4, the float 1 has an arched shape, particularly the shape of a banana or a croissant. In the preferred embodiment, shown in figure 1, the float 1 has a round or oval cross-section at least part of it, surrounded by water. Therefore, in performing the roll of the float relative to its longitudinal axis is minimal opposition. In the embodiment shown in figure 2, the float 1 is made in the form of an ellipse or oval and anchored cable 8 in the position in which the major axis of the ellipse or oval forms an acute angle with the direction of movement of the waves.

Common to structures of the float 1, shown in figure 1-4, is that, as the waves reach the float at an angle, float performs a circular movement, as the point of the triangle formed by its ends and its Central part, rise and fall in different phases. The ellipse shown in figure 2, contains two such doing the circular motion of the triangle, facing each other, with the result that the direction should be chosen in such a way that triangles do not lie symmetrically with respect to the direction of movement of the waves, and thus it cannot simply rocking back and forth and transform this movement into a circular movement. This also contributes to the hcpa the op perate, implemented mass following rotator, which during its rotation always tends to tilt the power plant mainly in the direction in which the counter (push), carried out by floats, is minimal.

Embodiments of the shown in figure 1-3 contain similar elements 5, 6, 7 for converting circular motion into rotation for PTO. Heavy rotator 6 is mounted on the bearing for rotation around doing the circular motion of the axis 5, is attached to the float 1. The rotator 6 is connected with doing the circular motion of the axis 5 with the lever 7 to the appropriate length. The length of the lever can be adjusted pneumatically or hydraulically, resulting in energy produced by the rotator during their rotation, can be adjusted according to the size of one after the other waves. Axis 5 is rotated by the rotator 6, may be adapted to drive an electric generator. In a practical embodiment, the rotator 6 together with its lever 7 and the axle 5 (which together make up the rotator can be installed in a hollow closed float. Because the rotator 6 applies downward force of gravity, it begins to rotate at run time axis 5 a circular motion. Axis 5 is moved along the trajectory and forms a cone, the cross is s which may differ from circle to be for example, in the form of an ellipse, because the roll of the plant in different directions may be different.

Figure 4 illustrates another implementation of the device for PTO. The float 1 is suspended from the load 11 through a vertical rod 9. To the holder of the float 1 is attached to the axle 10, is designed as a continuation of the rod 9 with a small angular deviation α. This angular deviation α essentially selected to harmonize with the angular deviation in a circular motion of the float 1. Inside the rod 9 and the shaft 10 is mounted for rotation on the bearing angle of the shaft, in which the section is located on one side of his knee, lies within the axis 10, and section located on the other side of the knee, is mounted rotatably on the bearing in the rod 9. Because the rod 9 and the load 11 does not perform a circular motion, angular shaft does rotate when the float 1 performs a circular movement. Therefore, the rotating angle of the shaft can be selected energy.

In variants of execution, shown in figure 5-7, used at least three of the float 2, attached to a common holder 3, so that their centers of buoyancy located along the arc 4. Thus, various floats 2 rise and fall in different phases, while the distance between them and their angular position relative to the direction magic cube MOV the I waves remain relevant. As a rule, the triangle formed by the three floats are placed on the anchor so that a straight line passing through two floats, coincides with the direction of the incoming waves. The holder 3 is forced to make a circular motion, the energy of which can be selected by the rotator 6, mounted on the bearing in a similar way, with the possibility of rotation on doing the circular motion of the axis 5. To eliminate axle load 5 under the rotator 6 can be performed in a guide groove to support her rotator 6 through the bearing. Of course, the PTO can be produced without the use of axis 5, and with the help of any cargo that moves in an arc. However, the use of a rotating axis 5 simplifies the PTO. Figure 6 shows the elongated floats 2, which form the swing carpet. The floats 2 are attached to the holder 3 by means of hinges, passing transversely to the longitudinal direction of floats. Even in this case, the fulcrum of floats 2 are located along the curve 4.

In an embodiment, shown in Fig.7, the floats 2 has a streamlined design and in this way provide the possibility of their connection with the vessel, which is supported by the floats 2 are forced to make a circular motion during the passage of a sequence of waves. To ensure a circular motion when choosing the x direction movement of the vessel floats 2 are preferably constructed with the ability to adjust their relative positions. Rotation obtained from circular motion, serves as the engine for the promotion of the vessel or rotation of the electrical generator, which set in motion in this way can be used for charging batteries, functioning as a source of energy for the ship.

On Fig illustrated an alternative embodiment of the invention, in which the blades 13, anchored below the surface of the water, interact with a common holder 14 such angles that the holder 14 performs a circular movement in response to the influence of currents inside the waves. Zakalivanie can be carried out, for example, by means of vertical rods 9 having anchor load 12 at the lower end. In this case, the energy extraction invited to perform with the angular shaft, clamped on the bearing in the axial sleeve 10 relating to the holder 14, and the rod 9 (or placed on the outside of the rod 9), so that the knee angle of the shaft is located between the rod 9 and the axial sleeve 10. When the axial sleeve 10 performs a circular motion with a small angular deviation α (which is equal to the angle of the knee angle of the shaft) from the rod 9, the angular shaft is forced to rotate. Here, as in the embodiment shown in figure 4, the angle of the knee angle of the shaft may vary around a single transverse shaft, resulting in the angle α of the implementation of circular motion between the y axial sleeve 10 and the rod 9 can be changed.

Figure 9 depicts an exemplary embodiment of elements that transform a circular motion into rotation. On the holder 3 or 14, similar to shown on figure 4 and 8, mounted on the sleeve 10 as an axis for rotation on the bearing in which is mounted the rod 9 in the form of the second axis with an angular deviation α rotatably on the bearing. When the axis 10 performs a circular movement, rigidly mounted on the bearing axis 9 axis forces 10 also make a rotation around its axis.

On the axis of rotation of the shaft 10 is fixed axis 5 for the selection of energy, which carries the actuator, such as an electric generator. The rod 9 may be provided with a hinge axis 15, which provides angular deviation that is different from the angle α between the rod 9 and the axle 10.

If necessary, the design shown in Fig can be performed under the structures shown in figure 1-6, for use thus the buoyancy force and energy of the internal currents of the same waves. Thus, the use of the rod 9 and the armature 12, shown in Fig is not required, and the energy extraction can be carried out using angular shaft made between the elements of the wave power plant, equipped with floats and blades. Of course, these elements of the wave power plant is part of their specific circular motion in different phases for forming between them an angular deviation α, providing angular rotation of the shaft.

In the embodiment shown in figure 10, the body of the rotator is made in the form of a hollow body of rotation, for example in the form of a sphere, a flattened sphere, cylinder, or in an intermediate form between the sphere and the cylinder. From the body 16 of the bit toward the direction of incoming waves passes tapered in the longitudinal direction of the arcuate float 1, so that between the direction of incoming waves and curved float 1 is formed an acute angle, which increased towards the tip of the float, and near the end of the float greater than 30°, preferably lies in the range of 30-70°. From the opposite side of the housing 16 in the direction of the flue passes the second arcuate float 1', which may be shorter float 1, so that between the float 1' and the direction of the departing waves also formed an acute angle, which increased towards the tip of the float 1'.

The rotator 6 has an external surface, consistent with the contour of the inner surface of housing 16. The rotator 6 is mounted on doing the circular motion of the axis 5 with the help of the support, which consists of vertical plates or more weights assigned to each other. In the housing 16 can also be posted by the generator 18 and, if necessary, transfer. The waterline of the float 1 approximately corresponds to the edge of the hatch.

SUBSTANCE: pitch-driven ship is a ship exploiting pitch energy to drive it at sufficient water heaving. Pitch-driven propulsor comprises elasto-vibrating wing that makes a propulsion generator. Said wing oscillates when ship hull pitches and is fitted on stream-lined posts-holders arranged below ship hull at preset depth. Water heaving at said depth can be considered zero, not decreasing the difference in vertical velocities of the wing and water (wing propulsion varies with square difference). To reach maximum wing propulsion, proposed propulsor is arranged nearby ship edge. Effect of separate wing increases if propulsor is mounted on every edge of the ship. Note that, in this case, propulsion and alternating acceleration are smoothed. Pitch-driven propulsor design is distinguished for by the number of posts-holders, i.e. one or two, and propulsor can be made lifting, rotary or fixed. Also there can be retractable wing extensions and wings can be made folding. Note that wing halves can vibrate independently. Proposed ship is with furnished with two pitch-driven propulsors. Flat horizontal flaps can be arranged on ship edges, nearby deadline, and screw propellers can be used in low heaving conditions.

EFFECT: increased range and speed, reduced fuel consumption.
