Abstract

A ship-borne wave-activated pendulum generator driven by turbulent motion comprises: a base (1), a pendulum generator (2), a pendulum rod (3), a pendulum bob (4), a sliding sleeve (5), and a damping spring (6). An inertial vibration member, which consists of the damping spring (6) and a mass block consisting of the pendulum rod (3) and the pendulum bob (4), absorbs wave energy which causes a hull (1000) to undergo turbulent motion. The wave energy is converted into unidirectional rotation of a generator rotor (25) by means of a one-way bearing mechanism, and the mechanical energy is temporarily stored in the form of rotational inertial energy. At the same time, a coil of a generator stator (24) couples with a magnetic field of the generator rotor (25) and a pulsed induced electric potential is generated. Finally, a rectification circuit and an energy storage battery are used to convert the pulsed electric potential into a stable voltage and power a ship-borne electrical load device. The wave-activated generator has a simple structure and high energy conversion efficiency and volume power density, is reliable, and is low-cost.

Description

A ship-borne pendulum-type turbulence-driven wave generator

technical field

The invention belongs to the field of new energy equipment, and in particular relates to a ship-borne rotary-pendulum-type pitch-driven wave generator.

Background technique

Small ships such as small yachts, fishing boats, and transportation boats need power even when they are at anchor to provide lighting, communication, and some domestic electricity and low-power production electricity. The electricity is stored as a power supply. While permanent floating units such as marine communication towers, beacon lights, fish ponds and cage aerators also require electricity, fuel powered units are often inconvenient due to volume constraints, cost and efficiency of use, and inconvenient maintenance. To generate electricity to solve the problem of power supply, the battery is generally used for power supply and replaced regularly.

In order to reduce power consumption and save energy, there are also ships and floating devices that use wind power or solar cells as mooring backup power sources or permanent power sources, but such methods have complex energy conversion mechanisms, large volume and weight, and low power density per unit volume. Due to the disadvantages of high installation and maintenance costs, high installation location and poor wind resistance, it is difficult to be popularized. In fact, the surging waves in the rivers, lakes and seas contain huge energy and are much higher than the energy density of wind and sunlight. There are also some coastal power stations that use waves to generate electricity, but their mechanisms are relatively complex and it is difficult to achieve volume and size. The weight is miniaturized, the design working conditions are harsh, and the cost is high, so it is difficult to be transplanted and applied to small ships and permanent floating devices.

Therefore, it is necessary to develop a small wave power generation device that utilizes the high-density energy contained in waves, high power conversion efficiency and power density, small volume and size, reliable operation, low cost, and convenient maintenance as a mooring backup power source or floating device for small ships. daily operating power.

In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.

Referring to Figure 1, Figure 2 and Figure 4, this embodiment discloses a ship-borne pendulum-type pitch-driven wave generator, including a base 1, a pendulum generator 2, a pendulum rod 3, a pendulum 4, and a sliding sleeve 5 and damping spring 6;

The two pendulum generators 2 are respectively arranged symmetrically on the left and right sides of the machine base 1 through their respective motor bases 21 , and the pendulum generators 2 on both sides have their own pendulum rods 3 and are connected to each other by means of the pendulum rods 3 . The pendulum 4 and the sliding sleeve 5 are slidably sleeved on the pendulum rod 3 and the damping spring 6 is respectively supported on the sliding sleeve 5 and the base 1 in two upper and lower sections. The pendulum generator 2 can play the role of the pendulum 4 to drive its work to achieve power generation.

In this embodiment, the pendulum generator 2 includes a motor base 21 , an inner bearing 22 , a main shaft 23 , a generator stator 24 , a generator rotor 25 , an outer bearing 26 , a one-way bearing 27 and a chuck 28 . The disc 28 is embedded in the upper end of the motor base 21 , the lower end of the main shaft 23 is set at the center of the motor base 21 through the inner bearing 22 , the upper part of the main shaft 23 is set at the center of the chuck 28 through the outer bearing 26 , and the generator stator 24 is set around the main shaft 23 at the center of the chuck 28 . On the motor base 21, the generator rotor 25 is embedded in the main shaft 23 and wraps around the generator stator 24;

The main shaft 23 is also connected to the swing rod 3 through a one-way bearing 27, and the main shaft 23 is fixedly connected to the generator rotor 25;

The pendulum generators 2 on both sides each have its own pendulum rod 3 set on the upper end of the main shaft 23 through a one-way bearing 27 , the pendulum 4 is set on the lower end of the pendulum rod 3 , and the sliding sleeve 5 is slidably sleeved on the pendulum rod 3 . The upper and lower damping springs 6 are respectively supported on the sliding sleeve 5 and the base 1 in two upper and lower sections.

In this embodiment, the voltage output coil of the generator stator 24 is connected to the onboard electrical load through a rectifier circuit and a rechargeable battery.

In this embodiment, the generator stator is mainly composed of an induction coil, and the generator rotor is composed of inner magnetic poles and a counterweight ring whose outer ring mainly plays the role of increasing rotational inertia.

In this embodiment, in this embodiment, the machine base 1, the pendulum rod 3, the pendulum 4, and the sliding sleeve 5 are made of metal materials, and the damping spring 6 is made of spring steel; the inner bearing 22 of the pendulum generator 2 , The outer bearing 26 and the one-way bearing 27 are made of standard or customized parts, the generator stator 24 and the generator rotor 25 are made of mature technology customized parts, and the other parts are made of metal materials; the parts and components of the electrical system can be made of existing Technical customization.

The working process of this embodiment is as follows:

A typical application case of this embodiment is shown in FIG. 5 , and this embodiment only needs to be installed in a power compartment at the bottom of the hull of a small ship and its electric output end is connected to an electric load. In the process of anchoring or sailing of the ship, the hull will bump up and down with the ups and downs of the waves, so the machine base 1 of the present invention also bumps up and down with the hull, and the pendulum rod 3, the pendulum 4 and the sliding sleeve 5 on the left and right sides constitute The inertial mass of the whole tends to keep its original position due to inertia. When the ship moves upward with the waves, the inertial mass will rotate downward around the pivot of the swing rod 3 as a whole, and the damping spring 6 also begins to deform to store energy, so the one-way bearing 27 through which the swing rod 3 passes (at this time it is locked stop state) to drive the main shaft 23 of the pendulum generator 2 to rotate and drive the generator rotor 25 to rotate and temporarily store part of the mechanical energy in the form of rotational inertial energy. When the pendulum rod 3 rotates down to the limit position, the rotation stops, and the main shaft 23 and the generator rotor 25 continue to rotate in the forward direction due to inertia without being restrained by the one-way bearing 27 (they are in an unlocked state at this time), so the power is generated. The coupling of the stator coil of the machine and the magnetic field generated by the magnetic pole of the rotor generates a pulsating induced potential. Finally, the inertial mass composed of the pendulum 3, the pendulum 4 and the sliding sleeve 5 is integrated by the rectifier circuit and the energy storage battery of the rectifier power storage module. According to the contained mechanical energy converted into voltage-stable electrical energy, the shipboard electrical load equipment is continuously supplied with power.

When the ship moves downward with the waves, the inertial mass will rotate upwards around the pivot axis of the swing rod 3, and the damping spring 6 starts to reset. During this process, the one-way bearing 27 is in the unlocked state, so it will not hinder the main shaft at this time. 23 and the generator rotor 25 still keep rotating forward due to inertia, so the rotational inertial energy stored in the generator rotor 25 is still being converted into electrical energy to continuously supply power to the onboard electrical load equipment.

In the above-mentioned one-cycle up-and-down motion, the left and right swing drive mechanisms interact with the corresponding swing generators 2 and the electromechanical motion process occurs synchronously, and the time course is synchronous.

Therefore, with the ups and downs of the ship, the above process is repeated between the entire inertial mass and the corresponding pendulum generator 2. Therefore, the present invention enables the ship to contain the ship's turbulence caused by waves in the process of anchoring or sailing. The mechanical energy is converted into electrical energy and continuously powers the ship's electrical load equipment.

Example 2

As shown in FIG. 3 and FIG. 4 , the rest is the same as that of Embodiment 1, except that the main shaft 23 is connected to the generator rotor 25 through a one-way bearing 27 , and the main shaft 23 is fixedly connected to the swing rod 3 .

The working process of this embodiment is as follows:

A typical application case of this embodiment is shown in FIG. 5 , and this embodiment only needs to be installed in a power compartment at the bottom of the hull of a small ship and its electric output end is connected to an electric load. In the process of anchoring or sailing of the ship, the hull will bump up and down with the ups and downs of the waves, so the machine base 1 of the present invention also bumps up and down with the hull, and the pendulum rod 3, the pendulum 4 and the sliding sleeve 5 on the left and right sides constitute The inertial mass of the whole tends to keep its original position due to inertia. When the ship moves upward with the waves, the inertial mass will rotate downward around the pivot of the swing rod 3 as a whole, and the damping spring 6 also begins to deform to store energy, so the swing rod 3 drives the main shaft 23 to rotate, and the main shaft 23 relies on the one-way bearing 27 (which is now in the locked state) drives the generator rotor 25 of the pendulum generator 2 to rotate and temporarily preserves part of the mechanical energy in the form of rotational inertial energy. When the pendulum rod 3 rotates down to the limit position, the rotation stops, and the generator rotor 25 continues to rotate in the forward direction due to inertia without being restrained by the one-way bearing 27 (it is in an unlocked state at this time), so the stator of the generator The coupling of the coil and the magnetic field generated by the magnetic poles of the rotor generates a pulsating induced potential. Finally, the rectifier circuit and the energy storage battery of the rectifier power storage module are used to make the inertial mass composed of the pendulum 3, the pendulum 4 and the sliding sleeve 5 as a whole according to the contained The mechanical energy is converted into voltage-stable electrical energy to continuously supply power to the ship's electrical load equipment.

When the ship moves downward with the waves, the inertial mass will rotate upwards around the pivot axis of the swing rod 3, and the damping spring 6 begins to reset. During this process, the one-way bearing 27 is in the unlocked state, so it will not hinder the power generation at this time. The generator rotor 25 still maintains a forward rotation due to inertia, so the rotational inertial energy stored in the generator rotor 25 is still being converted into electrical energy to continuously supply power to the onboard electrical load equipment.

It is known from the technical common sense that the present invention can be realized by other embodiments without departing from its spirit or essential characteristics. Accordingly, the above-disclosed embodiments are, in all respects, illustrative and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
