BEST MODE

[0021] Preferred embodiments of the present invention will be described in detail below based on the accompanying drawings. In FIGS. 3 to 6, the same reference numerals are assigned to components that perform the same functions. Meanwhile, in the illustration of the drawings and the detailed description, detailed descriptions and illustrations of specific technical configurations and operations of elements not directly related to technical features of the present invention are omitted, and only the technical configurations related to the present invention are briefly illustrated or described.

[0022] Referring to FIGS. 3 to 6, a power-generating and rotating road marker using a magnet according to a preferred embodiment of the present invention is configured to include a waste golf ball 20, a body part 30, a protective cap 40, a fastening plate 50, a magnetic electrode unit 60, and a light emission unit 70.

[0023] A space is formed in the waste golf ball 20 so that the magnetic electrode unit 60 and the light emission unit 70 are accommodated and disposed in the waste golf ball 20, a cylindrical groove 21 is formed inward in the center portion of the upper portion of the outer circumferential surface of the waste golf ball 20, and a rotation element 22 is inserted into the groove 21 and enables stable rotation during horizontal rotation in the seating depression 42 of the protective cap 40 to be described later.

[0024] The body part 30 is laid under a road surface, the material of the body part 30 is aluminum, and the section of the body part 30 has a T shape. In other words, a raised edge 32 is formed along the edge of the top surface 31 thereof, a seating depression 33 in which the lower portion of the waste golf ball 20 is seated is formed in the center thereof, and an anchor 35 which is laid under a road surface is formed downward from the center of the bottom surface 34 thereof.

[0025] Meanwhile, although the anchor 35 configured to be laid under a road surface is formed in a straight cylindrical shape in a preferred embodiment of the present invention, this is merely an embodiment. However, a plurality of stop protrusions (not shown) may be formed on the cylindrical outer circumferential surface of the anchor 35, and may thus be fixed in a road surface.

[0026] The protective cap 40 is coupled to the top surface 31 of the body part 30, and is intended to prevent the waste golf ball 20 from being separated and to protect the waste golf ball 20 from external shocks, etc. The protective cap 40 is made of a hemispheric transparent material in which a support protrusion 41 protrudes outward from the edge of the lower end of the protective cap 40 and a seating depression 42 is formed inside the protective cap 40 so that the upper portion of the waste golf ball 20 is located therein. In this case, a groove 43 is formed in the center side of the top of the inner circumferential surface of the seating depression 42, i.e., at a location corresponding to the groove 21 of the waste golf ball 20.

[0027] As described above, the horizontal rotation of the waste golf ball 20 located in the seating depression 42 of the protective cap 40 is facilitated in such a way that the rotation element 22 functions as a rotating shaft, and vertical rotation and the like other than horizontal rotation may be prohibited.

[0028] As described above, the protective cap 40 is coupled to the top surface 31 of the body part 30 and the waste golf ball 20 is located in the seating depressions 33 and 42 of the body part 30 and the protective cap 40, thereby providing an effect in which when a wheel of an automobile applies pressure to the protective cap 40, the waste golf ball 20 will mitigate a shock by performing a shock-absorbing action.

[0029] The fastening plate 50 is intended to be tightly fastened to the top surface 31 of the body part 30 and to prevent the waste golf ball 20 and the protective cap 40 from being separated. The fastening plate 50 is formed to have a diameter slightly larger than the inner diameter of the raised edge 32 formed on the top surface 31 of the body part 30, and is press-fitted into the inside of the raised edge 32. Meanwhile, a through hole 51 which is fitted over the protective cap 40 downward from a location above the protective cap 40 is formed in the center portion of the fastening plate 50.

[0030] Meanwhile, although the fastening plate 50 is press-fitted into the inside of the raised edge 32 formed on the top surface 31 of the body part 30 in the power-generating and rotating road marker 10 using a magnet according to the preferred embodiment of the present invention, this is merely an embodiment. It will be readily understood by a person of ordinary skill in the art that various modifications and alterations may be made within the range not departing from the technical spirit of the present invention, including a method in which threads are formed on both the inner circumferential surface of the raised edge 32 of the body part 30 and the outer circumferential surface of the fastening plate 50 and the inner circumferential surface and the outer circumferential surface are screwed into each other, or a method in which the fastening plate 50 is fastened to the body part 30 by bolts.

[0031] The magnetic electrode unit 60 includes a support shaft 61 configured such that it is coupled to the center portion of the seating depression 33 of the body part 30 in a vertical direction and a coil 71 connected to the light emission unit 70 is wound thereon, a magnetic bearing 62 disposed on the support shaft 61, and a plurality of electrode plates 63 formed in arcuate shapes and spaced apart from the magnetic bearing 62. As the plurality of electrode plate 63 repeats left and right rotations around the magnetic bearing 62, power is generated, and the light emission unit 70 receives the generated power and flickers.

[0032] In this case, the magnetic bearing 62 and the electrode plates 63 are formed to have the same polarity. The reason for this is that the magnetic bearing 62 and the electrode plates 63 can be spaced apart from each other and perform left and right rotations only when they have the same polarity. In other words, when the magnetic bearing 62 and the electrode plates 63 have different polarities, they are not spaced apart from each other, and do not perform rotations due to their attractive force, thereby not generating power.

[0033] The light emission unit 70 is disposed to come into close contact with the inner circumferential surface of the waste golf ball 20, is connected to the magnetic electrode unit 60 through the coil 71, and emits light by using power generated by the magnetic electrode unit 60. In this case, the light emission unit 70 includes LEDs.

[0034] In accordance with the power-generating and rotating road marker using a magnet according to the present invention, an effect arises in that the magnet is inserted into the waste golf ball and light is emitted using power generated via the magnet, so that a vehicle driver can easily identify a road even at night, thereby enabling the vehicle driver to perform safe driving.

[0035] In particular, an effect arises in that the magnetic electrode unit is disposed in the waste golf ball, power generated by the magnetic electrode unit is supplied to the light emission unit, and the light emission unit is allowed to flicker, so that a vehicle driver can easily identify the flickering light emission unit and thus perform safe driving even at night, thereby preventing a traffic accident from occurring.

[0036] Meanwhile, a power-generating and rotating road marker 10 using a magnet according to a preferred embodiment of the present invention may be configured such that a sensor is formed in a waste golf ball 20 and a sensor configured to communicate with the former sensor is mounted on a vehicle, so that when the vehicle approaches the power-generating and rotating road marker 10 using a magnet, which is laid in a line of a road, an alarm is issued and warns a driver of lane departure.

[0037] Although the above-described power-generating and rotating road markers using a magnet according to the preferred embodiments of the present invention are illustrated based on the foregoing description and drawings, this is merely an example. It will be readily understood by a person of ordinary skill in the art that various modifications and alterations may be made without departing from the technical spirit of the present invention.
