Description

Power generation rods and power generation devices using them

The present invention relates to a power generation rod and a power generation device using the same, and more specifically, to a power generation rod and a power generation device using the same, which produce electricity by energy generated by the shaking when ships and floating bodies are shaken by waves.

Recently, the use of environmentally friendly natural energy has been encouraged, and various power generation methods using solar energy, wind power, wave power, tidal power, and geothermal energy are already being actively developed. However, at present, only solar and wind power facilities have been put into practical use, and the remaining fields have not been widely put into practice due to many problems with economic feasibility and technical aspects.

Meanwhile, recently, due to environmental issues such as restrictions on greenhouse gas emissions, laws are being enacted around the world to limit fossil fuels and use electricity as power. The demands of environmental groups concerned about air pollution are becoming stronger, and the introduction of eco-power systems that use clean energy as power for ships, like cars, is being called for. Until now, the problem of exhaust gas at sea has not been discussed as seriously as on land, but the recent increase in the size of ships and the number of operations is greatly polluting the air, especially in coastal areas, and countermeasures are required.

In the case of ships using motors, lightweighting is essential to save energy, and recently, a lot of research is being done on aluminum ships to reduce weight.

Additionally, various research is being conducted to increase battery charging efficiency and utilize solar energy, wind power, and wave power.

Republic of Korea Patent No. 10-1255728, a marine wave power generator, discloses a marine wave power generator that generates power using wave power while the vessel is sailing or operating, and can implement a hybrid electric line that uses both commercial power and an internal combustion engine. .

Conventional marine wave power generation devices produce electricity by turning turbines when waves hit. Also, when it is fixed to a ship and receives wave power, additional work is required to insert and raise the underwater turbine, and there is a problem that the efficiency of ship propulsion is reduced due to a lot of resistance.

Additionally, installation is difficult because the turbine must be installed to operate by waves.

The present invention seeks to provide a power generation rod that can generate power using the shaking of a ship and a power generation device using the same.

The present invention seeks to provide a power generation device capable of producing power in response to shaking in three axes.

The power generation rod according to an embodiment of the present invention includes a hollow rod in the form of a tube with an empty interior; A coil surrounding the hollow rod; A support rod inserted into the hollow of the hollow rod and along the longitudinal direction of the hollow rod; a magnetic material inserted into and coupled to the support rod so as to be reciprocatable along the support rod; And a cap coupled to the end of the hollow rod to secure the support rod and prevent the magnetic material from being separated.

In an embodiment of the present invention, the cap is characterized in that it is made of an elastic material.

A power generation device according to an embodiment of the present invention includes a first power generation rod disposed in a first direction; A connector connected to the first power generation rod; a second power generation rod connected to the connector and disposed in a second direction; and a third power generation rod connected to the connector and disposed in a third direction.

In an embodiment of the present invention, the first direction, the second direction, and the third direction are formed to be orthogonal to each other.

In an embodiment of the present invention, the connector is characterized in that a fitting groove is formed into which the first to third power generation rods can be coupled.

According to the present invention, since power is produced using the shaking of the ship, installation is simpler and efficiency can be increased compared to the conventional method of directly rotating the turbine by waves.

In addition, according to the present invention, power can be produced for shaking in all three axes of x, y, and z, so power can be produced no matter which direction the ship shakes.

In addition, there are no exposed or protruding parts on the outside of the ship or floating body, so there is no additional resistance during navigation, and there is no risk of damage due to collision with external objects.

Figure 1 shows a power generation rod according to the present invention, Figure 1 (a) shows an exploded view, and Figure 1 (b) shows a combined cross-sectional view.

The power generation rod according to the present invention includes a hollow rod 110 in the form of a tube with an empty interior, a coil 120 surrounding the hollow rod, a support rod 130 inserted into the hollow rod and inserted along the longitudinal direction of the hollow rod, and It includes a magnetic body 140 that is inserted into and coupled to the support rod so as to be able to reciprocate along the support rod, and a cap 150 that is coupled to the end of the hollow rod to fix the support rod and prevent the magnetic body from being separated.

The hollow rod 110 and the support rod 130 may be made of a non-conducting plastic material.

After inserting the support rod 130 into the hollow 112 formed in the hollow rod 110, inserting the magnetic material 140 into the support rod 130, and blocking both ends of the hollow rod 110 with the cap 150, the support rod ( 130 can be fixed, and the magnetic material 140 can reciprocate along the support rod 130. The magnetic material 140 has a donut shape with a hole in the center, and the hole must be larger than the support rod 130.

Since a coil is wound around the outside of the hollow rod 110, electricity can be produced when the magnetic material 140 reciprocates along the support rod 130.

N: Number of turns around the coil

dΦ: change in flux linkage

dt: time change amount

And, according to the change in magnetic flux linked by the interaction between the curved coil associated with the 'six degrees of freedom movement of the ship' caused by wave power and the magnet inside the coil affected by gravity, the induced electromotive force (e) is expressed as Equation 2 below: .

[Equation 2]

e = -NωΦ,

N: Number of coil turns

ω: Angular velocity (=2πf), f = 1/T (period): Frequency

Φ = BS: magnetic chain linkage, S: area of coil, B: magnetic flux density, amount of magnetic flux passing through unit area

The cap 150 is coupled to both ends of the hollow rod to fix the support rod and at the same time prevent the magnetic material 140 from being separated when the magnetic material 140 moves. In addition, it is preferable that an elastic material is used to prevent the magnetic body from being damaged when the magnetic body 140 hits the cap 150. For example, elastic materials such as sponge or polyurethane can be used.

Figure 3 shows an example of a ship being arranged.

As shown in Figure 3, according to the present invention, installation is easy because the power generation device does not need to be in direct contact with waves, and there is no risk of damage to the power generation device by waves or other floating bodies.

Table 1 below shows the input values of the parameters of the above equation for simulation of the power generation device according to the present invention, and Figure 4 is a simulation in which power generated by the power generation device according to an embodiment of the present invention is charged to the battery. It shows the results.
