Description

Technical Field

[0001] The invention belongs to the field of new energy equipment, and in particular relates to a ship-borne impact-type swing-driven wave generator. Background Art

[0002] Small vessels such as small yachts, fishing boats, and transportation boats need power to provide lighting, communication, some daily life electricity, and small-power production electricity even when anchored. At present, batteries are generally used to store the electricity generated by the main power unit of the ship as a power supply. Permanent floating devices such as offshore communication towers, navigation lights, fish ponds, and cage aerators also need electricity. Due to factors such as limited size, cost, efficiency, and inconvenient maintenance, it is usually not convenient to configure fuel power devices to generate electricity to solve the power supply problem. Batteries are generally used for power supply and are replaced regularly.

[0003] In order to reduce power consumption and save energy, some ships and floating devices use wind power or solar cells as anchor backup power or permanent power supply, but this method has the disadvantages of complex energy conversion mechanism, large volume and weight, low power density per unit volume, high installation and maintenance costs, high installation position and poor wind resistance, so it is difficult to be popularized. In fact, the waves surging in rivers, lakes and seas contain huge energy and are far more energy dense than wind and sunlight. Some shore power stations also use wave power generation, but their mechanism is relatively complex, it is difficult to achieve miniaturization of volume and weight, the design working conditions are harsh, and the cost is high, so it is difficult to transplant and apply to small ships and permanent floating devices.

[0004] Therefore, it is necessary to develop a small wave power generation device that utilizes the high-density energy contained in waves, has high power conversion efficiency and power density, is small in size and reliable in operation, low in cost, and easy to maintain as a backup power source for small ships at anchor or a daily operating power source for floating devices.

[0027] See also Figures 1 to 3 , this embodiment discloses a ship-borne impact-type swing-driven wave generator, comprising a base 1, a swing rod 2, a pendulum 3, an impact roller 4, an arc-shaped guide rod 5, a damping spring 6 and an impact generator 7;

[0031] The main shaft 703 is vertically supported in the motor base 701 through the main bearing 707 by means of a chuck 706 embedded in the middle of the motor base 701, and is supported at the center of the motor base 701 through a thrust bearing 702 embedded in the center of the chassis of the motor base 701;

[0032] The generator stator 704 is wound around the center of the chassis inside the motor base 701, and the generator rotor 705 is sleeved on the lower part of the main shaft 703 and covered on the upper part of the generator stator 704;

[0033] The external threaded sleeve 709 is sleeved on the upper part of the main shaft 703 through the one-way bearing 708, and the internal threaded hollow sleeve 710 is sleeved on the outside of the external threaded sleeve 709 through the transmission thread and driven by the disc-shaped return spring 711 to move upward and return to its original position;

[0034] The pressure cover 712 is embedded in the upper end of the motor base 701 , and the rubber cap 713 with a flange is sleeved on the upper part of the motor base 701 and is in close contact with the upper end surface of the internal thread hollow sleeve 710 .

[0035] In this embodiment, the voltage output coil of the generator stator 704 is connected to the shipboard electrical load through a rectifier circuit and a rechargeable battery.

[0036] In this embodiment, the generator stator is mainly composed of an induction coil, and the generator rotor is composed of an inner magnetic pole and an outer ring of a counterweight ring that mainly serves to increase the rotational inertia.

[0037] In this embodiment, the upper end of the disc-shaped return spring 711 is supported in the annular groove on the lower end surface of the internally threaded hollow sleeve 710 , and the lower end of the disc-shaped return spring 711 is supported on the flange on the inner side of the upper end of the chuck 706 .

[0038] In this embodiment, the base 1, the rocker arm 2, the pendulum 3 and the arc guide rod 5 are made of metal materials, and the damping spring 6 is made of spring steel; the impact roller 4 is a standard part or a customized part made of metal; the thrust bearing 702, the main bearing 707 and the one-way bearing 708 of the impulse generator 7 are standard parts or customized parts, the rubber cap 13 is made of impact-resistant rubber material, the return spring 711 is made of spring steel, the generator stator 704 and the generator rotor 705 are customized parts using mature technology, and the remaining parts are made of metal materials; the parts and components of the electrical system can be customized using existing technologies.

[0039] The working process of this embodiment is as follows:

[0040] Typical application cases of this embodiment are as follows Figure 4As shown, it is only necessary to install the present embodiment in the power compartment at the bottom of the hull of a small ship and connect its power output end to the power load. When the ship is anchored or sailing, the hull will swing left and right with the ups and downs of the waves, so the base 1 of the present invention also swings left and right with the hull, and the inertial mass composed of the swing rod 2, the pendulum 3 and the impact roller 4 tends to maintain its original position due to inertia. When the ship swings to the left with the waves, the pendulum 3 swings to the left relative to the base, so the impact roller 4 on the left side of the pendulum 3 will act on the impact generator 7 on the left side, and the impact roller 4 drives the internal thread hollow sleeve 710 to move to the left through the rubber cap 713 (at this time, the return spring 711 is compressed) and drives the external thread sleeve 709 to rotate in the positive direction through the coupling of the transmission thread between it and the external thread sleeve 709, and then drives the main shaft 703 and the generator rotor 705 to rotate in the positive direction through the one-way bearing 708 (at this time, it is in a locked state) and temporarily saves part of the mechanical energy in the form of rotational inertia energy. When the internal threaded hollow sleeve 710 is pressed to the lowest position, the coupling transmission between it and the external threaded sleeve 709 stops. At this time, the external threaded sleeve 709 stops rotating, while the main shaft 703 and the generator rotor 705 continue to rotate in the positive direction due to inertia without being constrained by the one-way bearing 708 (at this time it is in an unlocked state). As a result, the coupling of the magnetic field generated by the stator coil of the generator and the magnetic pole of the rotor generates a pulsating induced potential, and then the rectifier circuit and energy storage battery of the rectifier storage module are used to convert the mechanical energy contained in the ship's swaying caused by the waves into electrical energy with stable voltage and supply power to the ship's electrical load equipment.

[0041] When the ship swings to the right with the waves, the pendulum 3 swings to the right relative to the base, and the rubber cap 713 and the reset spring 711 begin to reset. The extension of the reset spring 711 drives the internal threaded hollow sleeve 710 to move to the right. During this process, the coupling of the transmission thread between it and the external threaded sleeve 709 drives the external threaded sleeve 709 to rotate in the opposite direction, so that the one-way bearing 708 is in an unlocked state, so it will not hinder the main shaft 703 and the generator rotor 705 from still maintaining forward rotation due to inertia. Therefore, the rotational inertia stored in the generator rotor 705 can still be converted into electrical energy and continue to supply power to the ship's electrical load equipment.

[0042] In the above-mentioned one cycle of left-right swinging motion, the interaction and electromechanical motion process between the impact roller 4 on the right side of the pendulum 3 and the impact generator 7 on the right side occur synchronously, but are in opposite phases in the time process.

[0043] Therefore, as the ship pitches left and right, the above process is repeatedly and alternately performed between the aforementioned pendulum 3 and the impulse generators 7 on the left and right sides. Therefore, the present invention enables the ship to convert the mechanical energy contained in the swaying of the ship caused by the waves into electrical energy during anchoring or sailing and continuously supply power to the ship's electrical load equipment.

[0044] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
