Description

TRIBOELECTRIC GENERATORS USING A TURBULENCE, VORTEX AND PERMANENT MAGNETS

The present invention relates to a triboelectric generator, and more particularly, to a triboelectric generator using turbulence, vortex, and permanent magnets that permanently generate electricity using turbulence and vortex at sea.

Recently, as interest in underwater facilities and environmental exploration for the purpose of developing submarine resources and for military and research purposes has increased, various underwater infrastructures such as underwater structure construction and submarine environment monitoring facilities have increased. In addition, the use of various underwater devices such as water temperature, location estimation, and monitoring sensors used in the underwater infrastructure is increasing. However, these underwater equipment are difficult to operate and maintain, and particularly have many problems in supplying power for long-term operation.

Devices used in aquatic environments are very expensive compared to ground devices and are expensive and time consuming to install. Therefore, it is operated by using a battery for a short-term operation, or it is used by connecting to the ground and a wire for long-term operation. However, long-term operation in a space away from the ground, such as submarine ecosystem and ocean current (algae) measurement, sea level monitoring, etc., is difficult to connect by wire, so periodic battery replacement is required. In addition, these operations are costly, time consuming, and labor intensive, and in the case of submarine operations, workers may be at risk.

The supply technologies for long-term operation of existing marine equipment can be divided into 1. wired connection, 2. periodic battery replacement method, and 3. power supply method using solar power. In case 1, stable power supply is possible, but the infrastructure construction cost to the work environment is very expensive, and periodic replacement of the wire is required.

Normally, in the case of 2, it is carried out by loading enough batteries for the duty cycle, launching them in the target area, and periodically or replacing the batteries. With this type of sensor and observation equipment, a buoy that can hold the electric field and a battery in a buoy floating on the surface and replace it, and in the case of gliders or moving floats, follow the current for 1 week to 1 month It is mainly used as a method of recovery after performance, and the buoy type is used in connection with a subsea sensor in a fixed place. In the case of using this type of power supply, it is necessary to periodically replace batteries and recover equipment using the ship, and it is necessary to operate the ship and manpower every time. Moreover, if it is connected to the submarine infrastructure, it is necessary to reconnect with the subsea sensor whenever the battery is replaced, and there is a risk of sensor and battery failure and electric shock.

As a method for solving this problem, the number of power generation devices using solar heat is increasing as shown in FIG. 3. In this case, the solar panel is installed on the top of the buoy or on the wing of the glider, and the power is supplied through regular / regular solar power generation. However, in this case, charging may not be possible depending on the weather of the sea, and the solar panel may be incapable of charging or damaged due to floating on the sea. In addition, it has the disadvantage that the facility area for power generation is large and the installation cost is high.

A patent related to a generator using friction electricity in the ocean has a device for generating friction electricity using waves. This patent is a device that installs a buoy on the sea level and generates triboelectricity using up and down motion and rotational motion caused by waves. However, this equipment has to be installed on the sea level, which can cause loss or damage by ships, and has the disadvantage that static electricity cannot be generated at a rate higher than the period of the wave. In addition, the presence or absence of power generation may be determined according to the size of the waves.

A rectifying diode is a diode composed of two terminals of an anode on the P-type side and a cathode on the N-type side by joining the PN type in a single crystal of silicon or germanium. Capacitors or capacitors are devices that store electrical capacity as electrical potential energy in electrical circuits. The inside of the capacitor has a structure in which two conductor plates are separated, and an insulator is usually placed between them. Electric charges are stored at the boundary between the surface of each plate and the insulator, and the amount of charges collected on both surfaces is the same, but the sign is opposite.

Insulators are materials that do not transmit electricity or heat, and are also called non-conductors. In practice, it indicates that the electrical conductivity or thermal conductivity is very small. Glass, ebonite, diamond, and rubber are electrical insulators, and cotton, asbestos, and ash are thermal insulators. These materials are also called insulators because they are also used to prevent heat or electricity from escaping. The material of the insulator 400 may be poly dimethyl siloxane.

Polydimethyl siloxane (PDMS) belongs to a group of high molecular organosilicon compounds, commonly referred to as silicones, and poly dimethyl siloxane is the most widely used silicone based organic polymer, and is particularly well known for its rheological properties.
