Description

Technical Field

[0001] The invention belongs to the field of new energy equipment, and in particular relates to a ship-borne impact-type turbulence-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.

[0026] See also Figures 1 to 3 , this embodiment discloses a ship-borne impact-type turbulence-driven wave generator, comprising a base 1, a slide bar 2, a slide sleeve 3, a damping spring 4, a cross arm 5, a top cone 6 and an impact-type generator 7;

[0030] The generator stator 704 is wound around the center of the chassis inside the motor base 701, and the generator rotor 705 is embedded in the lower part of the main shaft 703 through a one-way bearing 706 and is covered above the generator stator 704;

[0031] The outer edge of the head of the main shaft 703 is provided with a transmission thread and meshes with an internal thread hollow sleeve 709 sleeved on the outside thereof. The internal thread hollow sleeve 709 can be driven to move upward and reset by a disc-shaped reset spring 710;

[0032] The pressure cover 711 is embedded in the upper end of the machine base 1 , and the rubber cap 712 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 709 .

[0033] 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.

[0034] In this embodiment, the generator stator 704 is mainly composed of an induction coil, and the generator rotor 705 is composed of an inner magnetic pole and an outer ring of a counterweight ring that mainly serves to increase the rotational inertia.

[0035] In this embodiment, the upper end of the disc-shaped return spring 710 is supported in the annular groove on the lower end surface of the internally threaded hollow sleeve 709 , and the lower end of the disc-shaped return spring 710 is supported on the flange on the inner side of the upper end of the chuck 707 .

[0036] In this embodiment, the base 1, the slide rod 2, the sleeve 3, and the cross arm 5 are made of metal materials, the damping spring 4 is made of spring steel, and the main material of the top cone 6 is made of impact-wear-resistant rubber material; the thrust bearing 702, the main bearing 708, and the one-way bearing 706 of the impulse generator 7 are standard parts or customized parts, the generator stator 704 and the generator rotor 705 are customized parts with mature technology, the reset spring 710 is made of spring steel, the rubber cap 712 is made of impact-fatigue-resistant rubber, and the remaining parts are made of metal materials; the parts and components of the electrical system can be customized using existing technologies.

[0037] The working process of this embodiment is as follows:

[0038] 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 bump up and down with the ups and downs of the waves, so the base 1 of the present invention will also bump up and down with the hull, and the inertial mass composed of the sliding sleeve 3, the cross arm 5 and the top cone 6 tends to maintain its original position due to inertia. When the ship moves upward with the waves, the inertial mass as a whole will slide downward along the sliding rod 2 to reduce the distance between it and the base 1, so that the top cone 6 on the lower side of the cross arm 6 acts on the impulse generator 7 on the lower side, and the top cone 6 drives the internal thread hollow sleeve 709 to move downward through the rubber cap 712 (at this time, the reset spring 710 is compressed) and drives the main shaft 703 to rotate in the positive direction through the coupling of the transmission thread between it and the outer edge of the head of the main shaft 703, and then drives the generator rotor 705 to rotate in the positive direction through the one-way bearing 706 (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 709 is pressed to the lowest position, the coupling transmission between it and the outer edge of the main shaft 703 head stops. At this time, the main shaft 703 stops rotating, while the generator rotor 705 continues to rotate in the positive direction due to inertia without being constrained by the one-way bearing 706 (it is in an unlocked state at this time). Therefore, 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. Finally, the rectifier circuit and energy storage battery of the rectifier and energy storage module are used to convert the mechanical energy contained in the ship's turbulence caused by the waves into electrical energy with stable voltage and supply power to the ship's electrical load equipment.

[0039] When the ship moves downward with the waves, the inertial mass as a whole will slide downward along the slide bar 2 to increase the distance between it and the base 1, and the rubber cap 712 and the reset spring 710 will begin to reset. The extension of the reset spring 710 will drive the internal threaded hollow sleeve 709 to move upward. During this process, the coupling of the transmission thread between it and the outer edge of the main shaft 703 head drives the main shaft 703 to rotate in the opposite direction, so that the one-way bearing 706 is in an unlocked state, so it will not hinder 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 power the ship's electrical load equipment.

[0040] In the above-mentioned one cycle of up and down jolting motion, the interaction and electromechanical motion process between the top cone 6 on the upper side of the cross arm 6 and the impulse generator 7 on the upper side occur synchronously, but are in opposite phases in the time process.

[0041] Therefore, as the ship pitches up and down, the above process is repeatedly and alternately performed between the aforementioned inertial mass as a whole and the impulse generators 7 on the upper and lower sides. Therefore, the present invention enables the ship to convert the mechanical energy contained in the pitch of the ship caused by waves into electrical energy during anchoring or sailing and continuously supply power to the ship's electrical load equipment.

[0042] 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.
