Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piezoelectric element generator utilizing a potential energy of water,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piezoelectric element generator, and more particularly, to a piezoelectric element generator that transmits a force due to potential energy of water to a piezoelectric element, Device generator.

Recently, interest in green energy has been increasing due to the risk of depletion of fossil fuels and interest in the environment. Especially, as a method for stable development without causing additional environmental pollution, Research is being conducted.

BACKGROUND ART Generally, a power generation using a piezoelectric element is a type of power generation that transforms a weight of a moving means or a wind force into an upward and downward reciprocating motion, converts it to pressurized energy, and then transfers it to a piezoelectric element.

However, in the conventional power generation using the piezoelectric element, the power generation amount can be increased or decreased by the number of the moving means, the weight and the period of the moving means, and the power generation by the wind power There is a problem that the upward and downward reciprocation movements are not smoothly performed.

Therefore, various researches and developments have been carried out in order to utilize the wind or hydraulic power in the power generation using the piezoelectric element.

As one method of utilizing the potential energy of water in utilizing the hydraulic power, it is disclosed in Japanese Patent Application Laid-Open No. 2004-112935 (published on Apr. 4, 2004).

As shown in Fig. 1, a generator using fall of fluid disclosed in Japanese Patent Application Laid-Open No. 2004-112935 disclosed in Japanese Laid-Open Patent Publication No. 2004-112935 has a structure in which one side of a pedestal (a pedestal plate) is fixed, The upper part of which is fixed to the upper part. In the process of the liquid being introduced, the liquid sinks in the support plate, and when the support plate is inverted and the liquid is discharged, the upper part comes up again by the reaction force of the spring.

However, since the support plate serving as a fulcrum and the spring serving as a point of action are formed on the same side with respect to the support point, there is a problem that power loss can not be minimized during the power generation process using the drop of the liquid.

Further, when the support plate is reversed in the operation process of the generator using the drop of the fluid, since the continuously introduced liquid is positioned on the vertical line with the outer circumferential surface of one side of the support plate, the inflow liquid passes through the outer peripheral surface of the support plate, There may be a problem that the liquid flows downward, and the liquid that continues to flow may become a resistance element of the tray reversal.

In addition, since the angle of reversal of the base plate is equal to or greater than a right angle, there is a problem that it can not be easily returned.

The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to utilize the potential energy of water by a river or seawater which can receive energy continuously in the power generation using a piezoelectric element.

In addition, while the force due to the potential energy of water is transmitted to the piezoelectric element and the piezoelectric element vibrates and generates electricity by the transmitted force, the force is advantageous according to the work principle, but the work is made to be the same, And the like.

The potential energy of water is defined as the amount of potential energy of water in terms of the amount of work that conservation forces do to water during the movement of water from each location to the reference location, .

On the other hand, the definition of the potential energy of water can be thought of as the amount of work that can be done when the water moves to the reference point while receiving only the conservation power.

For example, if you turn a water mill by dropping water at an arbitrary height, you can get as much energy as the position energy of water at any height.

When the water flows into the inside of the mold through the water inlet and starts to be accommodated in the receiving tube, as shown in FIG. 14, the first rotating part 50 has a point of action The striking plate 53 coupled to the first rotary part 50 is connected to the plurality of upper protective films 150 of the first piezoelectric element part 300 because the weight of the other side coupled with the striking plate 53, And the other side where the striking plate 74 serving as a point of action is bonded is heavier than one side having the through hole 72a serving as a fulcrum of the second rotating part 70, One end of the rotating part 70 having the through hole 72a is positioned in contact with the lower end of the receiving tube 51 of the first rotating part 50 and the striking plate 74 coupled to the other end of the rotating part 70 is connected to the second piezoelectric element part 70 The upper protective film 400 is in contact with the plurality of upper protective films 400.

When the water continuously flows into the mold 210 and water is received in the receiving tube 51 to the full water level, as shown in FIG. 15, the first rotating part 50 has the inlet hole 51a serving as a fulcrum, The first rotary part 50 rotates in the counterclockwise direction around the fixed shaft 54 serving as the fixing point, and the first rotary part 50 rotates in the counterclockwise direction about the fixed shaft 54, At this time, as the receiving tube 51 presses the upper end of the contact bar 72 and rotates, the second rotating part 70 rotates clockwise about the fixed shaft 75 serving as a fixed point.

16, when the first rotating portion 50 continues to rotate so that the outer surface of the lower end of the receiving tube 51 comes into contact with the supporting rod 58, the rotation is controlled, and one end of the receiving tube 51 The second rotating part 70 is located inside the through hole 72a of the contact rod 72 and the water contained in the receiving tube 51 flows out to the water collecting tube 260 and acts as a point of action 17, the first rotation part 50 is fixed to the fixed part 50, which serves as a fixing point, as shown in FIG. 17, when the other side to which the striking plate 53 is attached is heavier than a side provided with the inlet hole 51a The striking plate 53 coupled to the first rotary part 50 rotates clockwise about the axis 54 to strike the plurality of upper protective films 150 of the first piezoelectric element part 300, The piezoelectric element 110 develops due to the vibration transmitted to the piezoelectric element 110 through the piezoelectric element 150.

At this time, as the pressing force on one side provided with the through hole 72a serving as the fulcrum of the second rotation part 70 is eliminated, the second rotation part 70 has the impact plate 74 serving as the action point, 18, the other side is heavier than one side provided with the through hole 72a serving as a force point. Thus, as shown in Fig. 18, The striking plate 74 coupled to the rotation unit 70 strikes the plurality of upper protective films 150 of the second piezoelectric element unit 400 and vibrates due to vibration transmitted to the piezoelectric element 110 through the upper protective film 150. [ So that the piezoelectric element 110 develops.
