Description

[0001]DESCRIPTION OF THE INVENTION A SYSTEM THAT GENERATES ELECTRICITY WITH THE MOVEMENT OF SEA WAVES Technical Field The present invention relates to an electric generator used in the energy sector to generate electricity from the movements of sea waves. Known state of the art Today, the most common current practice is the generation of electricity by converting the form of wave motion into pressure with buoys placed at the shore edge. The mobile equipment used in this electricity generation is exposed to seawater. For this reason, maintenance is costly and manufacturing is expensive. As this system transmits the potential energy in sea waves by changing the form, it causes extra power loss and the need for additional equipment. In the present techniques, there is no mention of any structure to prevent corrosion caused by sea water. In other present techniques, as the systems are installed far from the shore, the installation costs are very high and the continuous maintenance expenses are more costly than the existing systems. As a result of technical research summary of the application with the number 2016 / 08214; "The invention comprises buoys (1,2) which are made of a single part or as a group on a keel and have a very large bottom surface. On the bottom surface of the buoys (1,2) there are several venturi tubes (4) with open upper and lower openings. The buoy (1,2) moves the tubes (4) up and down while ascending to the wave crest or descending to the wave trough, and the water entering through the openings of the tubes (4) gains speed due to the narrowing throat and gains speed due to the narrowing throat, and the turbines (10, 11) located in the throat (9, 12) and the turbines (10, 11) rotate the alternator (13) to generate electrical energy. In other words, without any power transmission elements subjected to wave force or rubbing against one another, the alternators (13) are directly driven by seawater displaced by the movement of the tubes (4)." As can be seen, the system is related to the generation of electricity from sea waves, but it does not mention a structure that can provide a solution to the disadvantages mentioned above, and due to the inadequacy of the present solutions on the subject, it is necessary to make a development in the relevant technical field.

One purpose of the invention is to convert the up and down motion of the sea waves into continuous rotary motion by means of a power transmission mechanism. One purpose of the invention is to enable the power transmission shaft to transfer the up and down movement of the buoy to the gearbox system by means of the connecting part. One purpose of the invention is to provide a one-way bearing and a bearing housing for the bearing by means of a one-way bearing and a revised bearing housing for the bearing.

Coupling Detailed Description of the Invention In this detailed description, the preferred embodiments of the invention are described solely for the purpose of a better understanding of the subject matter and without any limiting effect. The present invention relates to an electric generator used in the energy sector to generate electricity from the movements of sea waves. The elements and functions used in the electric generator subject to the invention are as follows; The main housing (10) ensures the containment of the entire system. The power transmission shaft (20) ensures that the movement of the buoy (30) is transferred to the system. The buoy (30) is the passive element of wave movements and is designed so that the centre of gravity remains in the water. The shaft housing (40) holds the power transmission shaft (20) and is available for maintenance. The speed-boosting gearbox (50) enables the low-speed movement with high torque to be increased to speeds suitable for electricity generation. The alternator / generator (60) converts the rotational movement into electrical energy. The three-way reducer (70) ensures lossless transmission of the movement entering the system by turning 90 degrees. The power transmission chain (80) transfers the movement from the output of the speed increaser gearbox (50) to the alternator / generator (60). The power transmission mechanism (90) ensures that the up and down motion from the sea waves is converted into continuous rotary motion. The power transmission shaft connection part (91) enables the buoy (30) to transfer its up and down movement to the speed increaser gearbox (50) and three-way gearbox (70) systems. The trolley and cradle (92) enable the trolley, which is capable of carrying heavy loads, to move horizontally. The pressure plate (93) secures the power transmission shaft connection part (91) and the load carriage and slide (92) to each other and ensures that the surface to be used for power transmission withstands the pressure. The pressure plate (93) detects the load at the connection point of the crests and troughs of the sea waves, prevents the instantaneous application of load to the system and ensures continuity of movement, thus reducing the energy generation loss in the system to near zero. The one-way bearing and bearing housing (94) provides bearing retention by means of a one- way bearing and a revised bearing housing for this bearing. The rolling bearing (95) provides the bearing of the shafts thanks to the bearing inside. The tidal mechanism (96) provides the locking to enable the power transmission shaft (20) and the connection point to the system to be changed by tidal action. The fixed linear bearing (100) ensures a constant vertical movement of the power transmission shaft (20). The movable linear bearing (110) allows the slide shaft (120) to move vertically while preventing rotational movement. The guide shaft (120) is moved vertically by means of a moving linear bearing (110) to prevent rotational movement. The coupling (130) provides a lossless transfer of the rotational movement from the speed increaser gearbox (50). The working principle of the electric generator subject to the invention is as follows; The electric generator, which is used to generate electricity from the movements created by sea waves, is mounted on the pier or coastline. The main body (10) and the shaft housing (40) on it are fixed in such a way that they do not come into contact with water. The buoy (30) is positioned so that the centre of gravity of the buoy (30) is below the water surface, thus giving it a full suspension position. For changes in the sea water level due to tides, the tidal mechanism (96) ensures that it remains in the optimum operating position. With the wave effect to be formed, the buoy (30) and the power transmission shaft (20) to which it is connected start to move up and down. This movement in a constant vertical plane is ensured by the fixed linear bearing (100). In order to prevent the buoy (30) and the power transmission shaft (20) from rotating, a moving linear bearing (110) connected to the slide shaft (120) is used. The up and down movements are transmitted to the trolley and carriage (92) via the power transmission shaft connection part (91) on the power transmission shaft (20). The power transmission shaft coupling (91) transfers the vertical torque to the horizontal. In this way, the upward and downward linear movement is transmitted to the one- way bearing and bearing housing (94) as a circular movement. The rolling bearing (95) provides protection against flexing and bending. The one-way bearing and bearing housing (94), which are positioned to the left and right of the shaft, are positioned so that they are locked in opposite directions and ensure that the shaft rotates in one direction continuously in up and down movements. This rotation in one direction is firstly rotated on a single shaft by means of three-way gearboxes (70) and the rotation is transferred to the speed increaser gearboxes (50) via couplings (13). At the output of the speed increaser gearbox (50), the rotational movement is continuously transferred to the alternator / generator (60) via the power transmission chain (80). Thanks to this rotation, electrical energy is generated and can be used according to the need by using inverters.
