A description of the design and function of the equipment version 1

This variant of the equipment is intended for use in the coastal zone, eg to use the wave energy that strikes the barrier and then flows back. The apparatus comprises partially submerged shields 1 and 2, consisting of:

- packets of wood or other material enclosed in a frame, with the possibility of changing the packet area according to need;

- pontoons mounted under packages 21,

- wave dams 29 and

mole 30.

Under the influence of the wave reciprocating under the influence of the sliding wave mass, the floating pontoons mounted under the said packages, under the influence of an attacking wave, drive the structure of the slider 3 on the trolley 24 located on the platform 20 and connected to the two calipers 4. on the system of rollers 5 secured in the frames 6. As a result, the calipers 4, which are encircled by strong plate drive chains 8, pass in sliding motion with an independently rotating rotor 7 having two through-spindles 9 and 10 mounted on the bearings. At an angle, surround the sprockets 11 mounted outside the rotor 7 on the shaft 9 and the freewheeling sprockets 12 on the shaft end which serve as spacers. On the outside of the rotor 7 are inclined freewheeling, drive chain tensioning sprockets 13, which form a loop of the drive chain 8. Inside the rotor 7, two idler sprockets 14 are mounted on the shaft 9 with two short drive chains 16 which are in engagement with the two sprockets 15 mounted on the central shaft 10 and the tensioning mechanisms 17 of the drive chains 16 (see Fig. 8 - section B-B). The central shaft 10 is supported by bearings in the outer metal structure. The rotor 7, which is braked by the brake mechanism 18, is released when the calipers 4 reach the end position and automatically rotates 180 °. To make a turn, the sprockets 11 must make one turn before the rotor is braked and the calipers 4 reverse. Flywheel mounted for rotation equalization 23. The central shaft 10 obtains a high torque. The central shaft (10) obtains a high torque which is capable of rotating the generator rotor. The rotor of the electric generator also partially functions as a flywheel. The design of the device allows the center shaft to be rotated either to the right or to the left (see Figs. 5 and 6, respectively). By installing two sea rolls side by side, operating simultaneously, it is possible to provide rotation of two central shafts in opposite directions, such as rotating the rotor of an electric generator and rotating the stator in the opposite direction, but such generators are not known to be manufactured.

A description of the design and function of the equipment variant 2

This version of the equipment is designed for use on the high seas or in the ocean, where the waves are high up and down compared to the coastal area.

The design and operation of the device differs from Option 1, which captured the kinetic energy of the coastal waves by means of shields. In this variant, the floating pontoon 21 with vertical calipers 4 uses the height of the wave elevation and the force of gravity in the wave fall. Due to this, the following elements are excluded from the structure: shields 1 and 2, horizontal slider 3, dams 29 and pier 30.

Partially submerged in open sea or ocean water, the floating pontoon 21, together with a variable mass of ballast 25, is stabilized by trolley 24 to provide adequate lifting capacity. The pontoon 21 is movably connected to a structure of a vertical slider 22 attached to the calipers 4, which are secured by the drive chains 8 and are controlled by a system of rollers 5 secured in the frames 6. Under the influence of the waves, the system 21 and 25 built up. When the calipers 4 reach the end position, the brake 18 releases the rotor 7, which rotates 180 °. The sliding mechanism 22 of the caliper 4 and the pontoon 21 slide downward under the influence of gravity. The central shaft 10 obtains a high torque. Depending on the mounting position of the rotor 7 and the sprockets 11, 12 and 13, the central shaft 10 may rotate to the right or left, whereby the mechanism of operation is analogous to that of the machine 1.

option. Figures 5 and 6 show sea roll assembly schemes to provide rotor rotation to either the right or left, respectively.

To stabilize the movement of the pontoon 21 under various weather conditions, ballast water 25 is filled or pumped out. As a result, the sea reel is also capable of operating in severe storms.

The length h of the calipers 4 must be less than or equal to a possible wave height H.

In installations, use of Option 1 in offshore or ocean power plant

The power plant, schematically shown in Fig. 1, operates by sensing the forces of the coastal waves and the elevated level of the spillway flowing from the breakwater with a variable shield area 1 and 2 by mechanically converting the sensed force into the shafts.

10 left or right rotation. To ensure the stability of shields 1 and 2 in strong winds or storms, shield pontoons are filled with more or less ballast water and hydro turbine pumps are installed to ensure smooth rotation. The building of the power plant is based on metal structures. The generator room is insulated. There is an opening on the sides of the building for a floating crane, for assembly and repair.

Installations using option 2 in offshore or ocean power plants

The power plant shown schematically in FIG. 12, is designed for offshore or ocean operations. Under the influence of wave motion, the pontoons used in variant 2 of the device rise and fall in different ways. The calipers 8 should be of varying lengths to ensure even rotation.

The center shafts of the machine are connected to one or more power generators by means of friction clutches and impellers. Circuit diagrams can be different. For example, when installing an extra large generator, the following assembly diagram can be used: 2 marine reels - clutch - one electric generator - clutch 2 marine reels - flywheel.

The length of the calipers h must be less than or equal to a wave height H of 180 °. Filling a pontoon full of ballast water stops the machine.
