RU2343306C2 - Energy-producing floating platform - Google Patents

Abstract

FIELD: engineering industry.

SUBSTANCE: invention refers to water power engineering, and namely to water-borne vehicles producing electric energy used for external consumers and for its own movement. Energy-producing floating platform consists of a triangular-shaped platform with a power unit, which is elevated above water surface by means of columns, floats, piston-type pumps, and supports which are hinged to columns. Floating platform is equipped with wind impellers installed on brackets and being synchronously rotated by propelling screws with wheels. Between each support and float arranged are piston-type pumps. Inside each column there is an axle on lower end of which there installed is a propelling screw and a wheel, and the other axle end is taken out above the platform surface and is provided with a pulley. Over pulleys there passed is a flexible rope pulled over by a steering mechanism.

EFFECT: designing the maneuvering self-moving energy-producing floating platform which is capable of autonomous movement on water surface.

Description

The invention relates to hydropower. In particular - to watercraft that generate electricity for an external consumer and for their movement, using the excitement of the water surface and wind force, and applies to floating platforms raised on racks above the water surface.

Known wind power apparatus (FR 2468003 A, 04/30/1981). The device consists of a platform on which wind impellers are installed on two brackets. One ends of the brackets are connected by an axis. The other ends of the brackets are provided with rollers and have the ability to move along an arcuate guide. This design allows you to change the speed of rotation of the impellers by changing the angle between the brackets. For example, in stormy weather, to avoid damage, you can reduce the angle between the brackets, thereby reducing the speed of rotation of the impellers, as well as the drag of the entire apparatus. All impellers are mechanically combined and rotate one electric generator. To automatically adjust the angle between the brackets, depending on the strength of the wind, a special pressure sensor and a drive are provided.

Also known wave power plant (SU 1532722 A1, 12/30/1989), which can be selected as a prototype. The installation is designed to generate electricity and is a triangular-shaped platform, raised on three racks, supports and floats above the surface of the water. The platform is equipped with nine cylinders with rods that make up the piston pumps. The supports using the struts are pivotally connected to the platform, and the floats are pivotally connected to the supports. Between the supports and floats, nine piston pumps are additionally installed. When the surface of the water is rough, floats and supports make complex vibrations, moving the piston pump rods, which in turn pump the working fluid into the power unit, which includes a battery and a turbogenerator.

The disadvantages of the installation are that it is installed permanently and anchored and for reinstallation requires the use of additional vehicles, such as tugboats. In addition, it is difficult to carry out underwater repair and maintenance work on the platform, since the installation is constantly in the water, and for transferring it to land it is necessary to use lifting equipment.

The invention solves the problem of creating a maneuverable self-propelled energy-generating platform - a waveguide (EP), capable of independently moving on a water surface.

To achieve this technical result, an energy-generating platform-wave walker containing a triangular-shaped platform with a power unit, raised above the water surface on the uprights, floats, piston pumps, supports pivotally mounted on the uprights, according to the invention, is equipped with wind impellers mounted on brackets and synchronously rotated screw movers with wheels, while piston pumps are placed between each support and the float, an axis passes through each rack, at the lower end of which a screw propeller and a wheel are installed, and the other end of the axis is brought out above the platform surface and equipped with a pulley, and a flexible cable pulled by the steering mechanism is thrown over the pulleys.

EPV floats are equipped with propellers powered by energy generated by the elements of the platform itself, as well as wheels, which will facilitate the transportation of EPV to land for repair and maintenance work. To increase the maneuverability of the platform, the propellers are mounted on the axles, the axle pulleys are mechanically connected (using a flexible cable) and synchronously rotated in one direction or another by means of the steering mechanism.

The EPV device is shown in figure 1 and figure 2, which shows a top view and side view, respectively.

EPV is a triangular-shaped platform 1, supported by three floats 2 and supports 3. Three piston pumps 4 are placed between each support and the float 4. The supports are mounted on racks 5. An axis 6 extends inside the rack, at the lower end of which there is a screw propeller 7 and wheel 8. The other end of the axle is brought out above the platform surface and is equipped with a pulley 9. All three pulleys on the axles are connected by a flexible cable 10 passing through the steering gear 11. Two brackets 12 are mounted on the platform, connected by an axis 13. The other ends of the brackets are equipped with a ikami (not shown), which can roll along the groove of the arcuate guide 14. The wind impellers are mounted on the brackets 15. The bow of the platform is equipped with a breakwater 16. All the energy generated by the piston pumps and wind impellers is concentrated in the power unit 17, which includes a battery and a turbogenerator.

An energy-generating platform-wave walker operates as follows.

When the water surface is agitated, the floats 2 and supports 3 perform complex oscillations, moving the piston pump rods 4 articulated with them. The piston pump rods reciprocate and pump the working fluid into power unit 17. In the presence of wind, the wind impellers are simultaneously rotated 15. If the wind speed exceeds the permissible value, as well as to reduce the windage of the platform and reduce the speed of rotation of the wind impellers, the angle of attack α between the brackets 12 can be changed. To do this, the brackets equipped with rollers move towards each other along an arcuate guide 14. For the movement of the EPW on the surface of the water, screw propellers 7 are powered by the energy stored by the power unit. To maneuver (rotate) the platform, the screw propellers mounted on the axes 6 synchronously rotate in one direction or another. U-turn is carried out by the steering mechanism 11 by pulling the cable 10 thrown over the pulleys 9. For the maintenance and repair work, EPV can be pulled to land along a hard-surface inclined surface, or along rail tracks using a winch or in its own right. When this EPV rolls on wheels 8, and the floats stop.
