Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed on stairs, floors or roads in public buildings such as stations and in buildings with a large number of people such as department stores. Provided is a floorboard material using a ceramic composite material having a function of generating electric power by using the weight of a person or the weight of a vehicle traveling on a road. By laying stairs and corridors using this floorboard material, lighting in the corridors and auxiliary power for elevators and escalators can be supplied, and it becomes a building material that contributes to energy conservation. 2. Description of the Related Art A lighter ignition device is the most common product using a piezoelectric ceramic material. In this device, when a lever is pulled, a hammer hits a ceramic piezoelectric element, and a voltage emitted from the element causes a space discharge phenomenon to ignite gas. On the contrary, a device has been developed in which a voltage is applied to the ceramic piezoelectric element to generate stress strain in the element and the strain is taken out to perform a minute displacement motion. However, there are few examples where the ceramic piezoelectric element is applied to a device that contributes to energy saving. [0003] The problem is what kind of shape and size the piezoelectric ceramic material should be processed into. Furthermore, it is necessary to devise an electrode structure that can take out the electromotive force generated by the piezoelectric ceramics when combined as a floor board material. In addition, it is necessary to provide a method for safely and efficiently storing electric power generated from a plurality of piezoelectric ceramic floor board materials. In the present invention, when pressure is applied to a ceramic piezoelectric material (titanate such as BaTiO 3 or PbTiO 3 ), the atomic spacing of the material is distorted, which results. The electric potential due to the polarized light is taken out and used. In general data, the voltage generated is 1 for 1 gram per unit area.
It is said to be μV. This voltage can be increased up to about 1 V with respect to the weight change due to the weight of the person by adjusting the area and thickness of the piezoelectric ceramic material. Average floorboard material area is about 900 cm 2 (30 cm x 30 cm)
Is. How to tie the piezoelectric ceramic material into this area will be described. There are two methods of installation. One is a method of arranging a plurality of small piezoelectric ceramic materials. The other is a method in which the entire area of the floor board material is composed of one piezoelectric ceramic material. The respective configuration methods will be described below in order with reference to the drawings. FIG. 1 shows a basic processing shape of a ceramic material when a plurality of small ceramic materials are used to form one floor board material. The piezoelectric ceramic material is processed into, for example, a cylindrical shape as shown in the figure. Then, the metal electrodes 2 are attached to both ends of the piezoelectric ceramic material 1 by vapor deposition or the like. As shown in FIG. 2, the piezoelectric ceramic element processed as described above is used as a supporting material 3 having a high electrical insulation property.
Make a hole in the hole and insert the piezoelectric ceramic element into the hole.
The metal plates 4 are placed on the upper and lower sides so that the metal electrode 2 and the metal plate 4 are electrically connected. Further, the material 5 used for a normal floorboard is closely attached to the upper and lower sides thereof. FIG. 3 shows a cross-sectional view of the piezoelectric ceramic floorboard having such a structure. When pressure is applied to the floor plate material 5, the pressure is transmitted to the piezoelectric ceramic material and a voltage is generated across the piezoelectric ceramic material. The generated voltage can be taken out to the outside through the upper and lower metal plates 4. In such a system, even if the piezoelectric ceramic element is partially destroyed, it can be easily repaired by replacing the element only. On the other hand, it may be considered that the piezoelectric ceramic alone is processed into a shape that constitutes one floor board material. As shown in FIG. 4, the piezoelectric ceramic material is processed into a size (for example, 30 cm × 30 cm) as a floor board material,
The metal electrodes 7 are attached on the upper and lower sides by vapor deposition or the like. As in the case of FIG. 3, the thus processed element is provided with metal plates on the top and bottom so that the voltage can be taken out to the outside. Even if the floorboard material is constructed by any of the above-mentioned methods, it is possible to generate a voltage from the piezoelectric ceramic according to an external weight change such as the weight of a person.
The generated electromotive force is preferably about several volts per floor board material, but if extremely high pressure is applied for some reason, a large voltage will be generated, which is dangerous. In order to deal with such a risk factor, a varistor diode or a constant voltage diode is inserted between the upper and lower metal plates 4 so that no voltage higher than a certain voltage is generated between the metal plates 4. This diode also functions to prevent sparks due to discharge between the metal plates 4. Furthermore, the structure in which the piezoelectric ceramic element is sandwiched between metal plates basically also functions as a capacitor, and spike-like voltage that causes noise is automatically absorbed by the ceramic element itself. If a plurality of piezoelectric ceramic floor plate materials having such a function are arranged in a relatively large area and all metal plates 4 for taking out a voltage are connected in parallel, when one of the floor plates is stepped on, the voltage due to the pressure is applied. Can be taken out. The power that can be taken out increases in proportion to the frequency of stepping on the floorboard and the area. The generated voltage is sequentially accumulated, and a converter is attached so that the accumulated charges can be used as electric power outside. Embodiments of the present invention will be described below in detail with reference to the drawings. It is necessary to lay a plurality of floor board materials using piezoelectric ceramics over a large area.
For this purpose, it is necessary that the metal plate 4 for taking out the generated voltage is in contact with the adjacent floor plate material while maintaining electrical continuity. In order to realize such a mechanism, a metal box-shaped metal electrode having a structure shown in FIG. 5 is made. The box-shaped metal electrode 8 is made of a thin metal and processed into the shape shown in the figure. The depth of the box should be such that the normal flooring material 5 is just inside. Further, a plate spring-shaped electrode 9 formed by extruding from the inside of the box to the outside is attached around the box-shaped metal electrode. The electrodes 9 are box-shaped metal electrodes 8 that are adjacent to each other when laying floor plate materials using piezoelectric ceramics side by side.
By pushing with a spring force, it is possible to maintain continuity with each floorboard material. FIG. 6 shows a main body 10 and a sectional view of a piezoelectric ceramic floor board material when the box-shaped metal electrode 8 is used. In this embodiment, an example of using a plurality of small piezoelectric ceramic materials is shown. The varistor diode or the constant voltage diode 11 has a function of preventing an excessive voltage from being generated between the upper and lower voltage boxes 8. Next, an example of a method of extracting a voltage when a plurality of piezoelectric ceramic floor board materials are arranged will be described. FIG. 7 shows a simplified electric circuit when four piezoelectric ceramic floor board materials are arranged in a row. The lower electrode 12 (the lower side of the box-shaped metal electrode 8) of the piezoelectric ceramic floor board material is grounded to have a ground potential. On the other hand, the upper electrode 13 (upper side of the box-shaped metal electrode 8) is connected to the anode side of the diode 14. The cathode of diode 14 enters capacitor 15. By connecting in this way, the electrode 12 and the electrode 1
The forward voltage of the diode (approx. 1
The voltage exceeding V) is stored as a charge in the capacitor 15. The electric charge accumulated in the capacitor 15 is taken out through the diode 16, converted into an alternating current through an existing direct current alternating current converter, and connected to a commercial power supply device. In this embodiment, the number of floor plate materials is four and they are arranged linearly, but the method of extracting the voltage is the same even if the number of floor plate materials is increased and arranged in a plane. Further, as shown in FIG. 8, the upper electrode 13 can be grounded to have the ground potential. With such a configuration, the electrode on the side where the person walks becomes the ground potential, and the unnecessary potential generated on the floor surface is grounded. Further, the voltage change due to the power generation is taken out by the lower electrode 12, and the safety is high. However, in this case, as shown in the figure, the direction of the diode is connected in the opposite direction to that in FIG. FIG. 9 shows an example in which a piezoelectric ceramic floor board material is installed on a staircase. Electric wires are drawn from the electrodes 12 and 13 at the lateral ends of the piezoelectric ceramic floor plate material installed in each stage, and a diode is passed through the electrode 13 side, and then a power supply device 18 including a capacitor 15 and a DC / AC converter 17 Connect to. The electric wire on the electrode 12 side is also connected to the power supply device 18. The AC output 19 from the power supply device 18 is used as an auxiliary power supply for a commercial power supply. The power supply device 18 including the power storage device, the diode 14, the electric wire, and the like can be installed inside the stairs, and the space under the stairs can be effectively used. The present invention provides a floor board material having a power generating function using a piezoelectric ceramic material. This piezoelectric ceramic floor board material is installed on the stairs of a public building such as a station or a department store with a large number of people, and has a function of generating electricity by using the weight of a person ascending and descending the stairs. By laying stairs and corridors using this floorboard material, lighting in the corridors and auxiliary power for elevators and escalators can be supplied, and it becomes a building material that contributes to energy conservation. Also, by laying this floorboard material on the road, it is possible to generate power by changing the weight due to the running of the car,
It can be effectively used as an auxiliary power source for street lights. Although the square type floorboard material is shown in the embodiment shown in the drawings, any other shape such as a hexagonal shape which is convenient for laying a wide surface can be used as a piezoelectric material having a power generating function. Ceramic floorboard material can be made.
