The hydrostatically driven wave energy generating device can absorb the wave energy of the entire wave cycle to generate electricity. Its working principle is:

The installation height of the engine room 3 is lower than the minimum sea level when the seawater ebbs. When the waves drive the wave energy capture float 1 to move upward, the synchronous belt 2-2 moves upward under the traction of the wave energy capture float 1, and at this moment, the synchronous pulley 2-1 rotates forward. The speed of the synchronous pulley 2-1 is very slow, if it is directly connected with the two-way variable pump 3-9, the output flow will be very small, so the speed of the synchronous pulley 2-1 is accelerated by the gearbox 2-3 and then passed to the two-way pump. Variable pumps 3-9. At this time, the hydraulic oil enters the second oil inlet and outlet b of the two-way variable variable pump 3-9 from the oil tank 3-1 through the second check valve 3-7, and the hydraulic oil output from the first oil inlet and outlet a of the two-way variable variable pump 3-9 The high-pressure oil enters the first oil inlet c of the shuttle valve 3-8, and the high-pressure oil makes the first oil inlet c of the shuttle valve 3-8 open and the second oil inlet d closes. Finally, the high-pressure oil enters the one-way hydraulic motor 3-3 from the oil outlet of the shuttle valve, and the one-way hydraulic motor 3-3 drives the alternator 3-6 to generate electricity, and then converts the electric energy into direct current through the rectifier 3-5 and stores it in the Battery 3-4. So far, the wave energy absorption conversion in the first half cycle of the wave is completed.

When the synchronous belt 2-2 moves downward under the joint action of the wave energy capture float 1 and the balance stabilization mechanism 4, the synchronous pulley 2-1 reverses. The gearbox 2-3 accelerates the rotating speed of the synchronous pulley 2-1 and transmits it to the bidirectional variable variable pump 3-9. At this time, the hydraulic oil enters the first inlet and outlet oil port a of the two-way variable variable pump 3-9 from the oil tank 3-1 through the first one-way valve 3-2, and the high-pressure oil is output from the second inlet and outlet oil port b of the two-way variable variable pump. The second oil inlet d of the shuttle valve 3-8, the high-pressure oil makes the second oil inlet d of the shuttle valve 3-8 open, and the first oil inlet c closes. Finally, the high-pressure oil enters the one-way hydraulic motor 3-3 from the oil outlet of the shuttle valve, and the one-way hydraulic motor 3-3 drives the alternator 3-6 to generate electricity, and then rectifies and stores the electric energy. So far, the wave energy absorption conversion in the second half cycle of the wave is completed.

Below in conjunction with Fig. 3 illustrate the operating principle of balance stabilization mechanism 4:

When the wind and waves are strong, the power supply and drive module 4-8 receives an emergency signal, and by controlling the rotation of the servo motor 4-2, the piston 4-5 is moved upwards to compress the gas in the air cavity 4-6-1 to the air bag 4- In 7, seawater enters the seawater cavity 4-6-2 through the casing water hole 4-1-1 and the balance box water hole 4-6-3, the mass of the balance and stability mechanism 4 is increased, and the overall stability of the device is enhanced. When the working environment is stable, the servo motor 4-2 is controlled to rotate, so that the piston 4-5 moves downward, and the seawater in the seawater cavity is discharged into the ocean. At this moment, the wave energy capture float 1 captures wave energy.

The working principle of the synchronous belt tensioning mechanism is illustrated below in conjunction with Figure 4:

Movable tension pulley 2-8 and slide block 2-6 can slide freely on the guide rail. When the synchronous belt 2-2 is in a relaxed state, the sliding block 2-6 is subjected to a greater force by the piston rod of the hydraulic damper 2-10 and the compression spring 2-5 than the synchronous belt 2-2 acts on the movable tensioner 2-8 At this time, the slide block 2-6 slides towards the direction of the support 2-7, so that the timing belt 2-2 is tensioned. In the same way, when the synchronous belt 2-2 is in an over-tight state, the slide block slides toward the hydraulic damper 2-10, so that the synchronous belt 2-2 is loosened.

The working principles of the power supply and drive modules 4-8 are described below in conjunction with FIGS. 5 and 6:

As shown in Figures 5 and 6, the output voltage of the storage battery 4-8-1 is 48V; the inverter 4-8-2 converts the DC 48V of the storage battery 4-8-1 into AC 220V, which is used for the servo drive 4-8- 8 power supply; DC/DC power conversion module 4-8-3 converts the DC 48V of the battery 4-8-1 into DC 24V, which is used to drive the first photocoupler IC2 and the second photocoupler IC3 to amplify the pulse of the single chip microcomputer IC1 Signal; use the balance and stability controller voltage regulator chip 4-8-4 to convert the DC 24V output by the DC/DC power conversion module 4-8-3 to 5V, and supply power for the single-chip microcomputer IC1; the sensor voltage regulator chip 4-8-5 will The DC 5V output by the balance and stability controller chip 4-8-4 is converted into 3.3V to supply power for the sensor 4-8-7.

The MCU of the balance and stability controller 4-8-6 adopts the single-chip microcomputer IC1 of the model ATmega128, because the I/O port of the single-chip microcomputer IC1 can only output the pulse signal with a low level of 0V and a high level of 5V, and the servo driver 4- The control input of 8-8 requires a pulse signal of low level 0V and high level 24V. The function of the first photocoupler IC2 and the second photocoupler IC3 is to amplify the pulse signal of the single chip microcomputer IC1 to communicate with the servo The control input of the driver 4-8-8 is matched, and the signal isolation on the other hand improves the anti-interference of the balance and stability controller 4-8-6. When pin 14 of the single chip microcomputer IC1 outputs a pulse signal with a low level of 0V and a high level of 5V, pin 4 of the first photocoupler IC2 outputs a pulse signal with a low level of 0V and a high level of 24V. Pin 4 of a photocoupler IC2 isolates and amplifies the speed control signal and then inputs it to the speed control signal input end of the servo driver, thereby controlling the speed of the servo motor 4-2; in the same way, through the second photocoupler IC3, the single chip microcomputer IC1 The 51 feet can control the steering of the servo motor 4-2.
