FIG. 1 shows a frost preventing apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram of a frost preventing apparatus according to an embodiment of the present invention.

1 and 2, the freezing prevention device 100 may include a piezoelectric power generation unit 110, a wind power generation unit 120, a control unit 130, and a heating unit 140, The power storage unit 131, the commercial power unit 132, and the supply unit 133. [

The icemaker (100) can be installed on a road or a roadside. Here, the road includes a road on which a vehicle travels, and may include a road where frequent freezing occurs because the amount of sunshine is small, such as an entrance of a tunnel or a mountainous area.

Also, the road side means the outside of the road, and may further include a center separator of the road or peripheral facilities installed around the road. The surrounding facilities may include traffic lights, street lights, traffic signs, soundproof walls, overpasses, electric poles, and the like.

The piezoelectric power generation unit 110 can convert the impact energy such as pressure or vibration due to contact with the wheels of the vehicle running on the road 200 into electric energy and output it.

The piezoelectric power generating unit 110 may be installed on the road surface of the road 200 and may include a lower member 111, a piezoelectric element 112, a filler 113, and a top member 114.

The lower member 111 may serve as a base layer of the piezoelectric power generation unit 110. Accordingly, the lower member 111 can be made of a hard material having high strength. The lower member 111 may be provided with a piezoelectric element 112 and a concave groove may be formed at a position where the piezoelectric element 112 is installed so that the piezoelectric element 112 can be stably fixed.

The piezoelectric element 112 may be fixedly mounted on the upper surface of the lower member 111. The piezoelectric element 112 may serve to generate electricity when subjected to physical stimulation such as pressure or vibration. Therefore, when pressure or vibration due to the vehicle running on the road 200 is applied to the piezoelectric element 112 through the upper member 114, electric energy can be generated. The amount of electric energy generated in the piezoelectric element 112 is proportional to the magnitude of the force applied to the piezoelectric element 112.

The filler 113 may be formed to surround the piezoelectric element 112 which is located between the upper member 114 and the lower member 111 and is fixed to the lower member 111. The filler 113 may protect the piezoelectric element 112 from being damaged by external physical impact.

The phase member 114 may be provided on the upper surface of the piezoelectric element 112 to cover and protect the piezoelectric element 112. The image member 114 It can be mounted directly against the wheels of the vehicle. Accordingly, the phase member 114 may transmit the impact energy generated while contacting the wheel of the vehicle to the piezoelectric element 112.

The wind power generation unit 120 can convert rotational energy generated by a running wind or natural wind generated by a vehicle running on the road 200 into electric energy and output the electric energy.

Since the wind power generation unit 120 is a power generation device that generates electric energy by running wind or natural wind, the amount of electric energy generated at times may be different. For example, the wind speed of the running wind can be changed according to the speed of the traveling vehicle, and the wind speed of the natural wind can also vary depending on the climate change. Accordingly, the magnitude of the rotational energy that the wind power generator 120 receives from the running wind and the natural wind can be varied.

The wind power generator 120 may be installed in the surrounding facility 220 located on the roadside or the roadside. The wind power generation unit 120 can be installed at a position that can sufficiently receive the running wind and the natural wind while not interfering with the running of the vehicle.

In an embodiment of the present invention, the wind power generator 120 is installed on the upper surface of the center separator 210. The center separator 210 travels along the road 200 located at the left and right at a high speed so that the traveling wind generated by the traveling vehicle moves along the center separator 210. Therefore, if the wind power generator 120 is installed in the center separator 210, a relatively large amount of electric energy can be generated by the running wind of the vehicle traveling at high speed.

The wind power generator 120 may include a support 121, a rotary shaft 122, and a blade 123.

The support 121 may be installed on the road surface or the surrounding facility 220. The support base 121 is coupled to the bottom surface of the ground or the installation site to firmly fix the wind power generator 120.

The rotating shaft 122 may be rotatably coupled to the support 121. The rotating shaft 122 is engaged with the wing 123 so that when the wing 123 is rotated by the wind, the rotating shaft 122 can be rotated together.

The wings 123 are coupled to each other around the rotation axis 122 and a plurality of wings 123 may be formed radially around the rotation axis 122. The wings 123 may be formed in a curved surface structure to receive the wind more efficiently, and a plurality of blades 123 may be formed to efficiently receive wind in any direction.

Therefore, when the vehicle travels at high speed on the road 200 on which the median separator 210 is installed, the running wind generated by the running is supplied to the wing 123 installed at the upper end of the median separator 210, 123 can rotate at high speed.

The piezoelectric power generation unit 110 and the wind power generation unit 120 may be electrically connected to the control unit 130. The electric energy generated in the pressure generation unit and the wind power generation unit 120 may move through the control unit 130, (131). &Lt; / RTI >

The control unit 130 may store the electric energy generated by the piezoelectric power generation unit 110 and the wind power generation unit 120 and may supply the electric energy to the heating unit 140. [

The control unit 130 may include a power storage unit 131, a commercial power unit 132, and a supply unit 133.

The power storage unit 131 may store the electric energy generated from the piezoelectric power generation unit 110 and the wind power generation unit 120. The electric energy generated by the piezoelectric power generation unit 110 and the wind power generation unit 120 may be used immediately but since the number of times of using the freezing prevention apparatus 100 is small in the season except for the winter season, 131).

The power storage unit 131 may store the electric energy generated in the piezoelectric power generation unit 110 and the electric energy generated in the wind power generation unit 120 together in one storage space or may store them in the respective storage spaces .

The commercial power unit 132 can receive power from the existing installed power network.

The commercial power unit 132 may be used as an auxiliary power source in case the electrical energy stored in the power storage unit 131 is insufficient. For example, when the wind is not blowing or the traffic volume of the vehicle is not sufficient, the electric energy generated from the piezoelectric power generation unit 110 and the wind power generation unit 120 may be small. Accordingly, even if the electric energy stored in the power storage unit 131 is insufficient, the required power can be supplied from the commercial power unit 132.

The supply unit 133 can supply electric power from the power storage unit 131 or the commercial power unit 132 to the heat generating unit 140. The supply unit 133 may further include a power control unit that can supply or cut off power to the heat generating unit 140. [ The power source control device may be operated directly at a place where the anti-icing device 100 is installed, or remotely at another place.

The supply unit 133 may supply power to the commercial power unit 132 when the electrical energy stored in the power storage unit 131 is insufficient or exhausted during the supply of the electrical energy stored in the power storage unit 131 to the heat generating unit 140 Supply. Accordingly, even when electric energy stored in the power storage unit 131 is insufficient, the electric power can be continuously supplied to the heat generating unit 140, and the icemaker 100 can be stably driven.

The heat generating unit 140 may be embedded in the road surface of the road 200. The heat generating unit 140 can be installed on a road with a high frequency of icing due to a shortage of sunshine.

The heating unit 140 may be electrically connected to the control unit 130 and may receive power from the supply unit 133 in response to an instruction from the control unit 130. The power supplied to the heat generating unit 140 may be the power of the power storage unit 131 or the power of the commercial power unit 132 may be used. The control unit 130 may supply power from the commercial power unit 132 when the power stored in the power storage unit 131 is exhausted or less than a predetermined value.

The heat generating unit 140 may include a heat ray 141 and a heat ray protecting tube 142.

The heat line 141 may be installed on the road surface of the road 200 by being supplied with electric power from the supply unit 133 and radiating heat. The heating wire 141 may be formed of an electric wire, such as a nichrome wire, which generates heat when power is generally applied. The heat line 141 can heat the road 200 by radiating heat to increase the temperature to prevent freezing. The temperature of the heat line 141 can be adjusted by the control of the control unit 130. The heat line 141 may be installed to form a curvature so that the heat can be uniformly transmitted to the road 200. The heat line 141 may be installed as close as possible to the road surface of the road 200 so as to efficiently transmit heat to the road 200.

The heat ray 141 is installed in the heat ray protection tube 142 and the heat ray tube 142 can protect the heat ray 141 from an external impact or an external environment.

3 shows a frost preventing device according to another embodiment of the present invention. The differences from the above-described embodiment will be mainly described, and redundant description may be omitted.

Referring to FIG. 3, the wind power generator 120 may be installed in a traffic signal, which is one of peripheral facilities 220 located on the road side. As described above, if the surrounding facilities 220 such as the existing traffic lights and milestones are used as they are, the initial installation cost and time can be saved.

The wind power generation unit 120 may be installed at one side of the surrounding facility 220 and may convert rotational energy caused by traveling wind or natural wind generated by the vehicle running on the road 200 into electric energy and output the electric energy.

The support base 121 may be installed on one side of the surrounding facilities 220 to fix the wind power generating unit 120 to the surrounding facilities 220. The rotary shaft 122 is rotatably coupled to the support 121 and a plurality of blades 123 may be coupled to the rotary shaft 122 around the rotary shaft 122. The rotating shaft 122 can be rotated together with the wing 123 being rotated by the wind.

4 shows a frost preventing device according to another embodiment of the present invention.

The difference between this embodiment and the preceding embodiments is the shape of the wind power generator, and the rest of the configuration is the same as those of the previous embodiments, so the description of the same configuration will be omitted.

Referring to FIG. 4, the wind power generator 120 may be installed at one side of the road so as to convert rotational energy generated by running wind or natural wind by a vehicle running on the road 200 into electric energy and output the electric energy.

The support base 121 may be installed on one side of the road so as to support the wind power generator 120. The support 121 is extended from the bottom surface of the road by a predetermined height so that the wing 123 can be rotated at a predetermined height.

The rotary shaft 122 is rotatably coupled to the support 121 and a plurality of blades 123 may be coupled to the rotary shaft 122 around the rotary shaft 122. When the wing 123 is rotated by the wind, rotational energy is transmitted to the wind power generator 120 through the rotating shaft 122, so that electric energy can be produced.

5 is an enlarged view of a piezoelectric power generating unit of an anti-icing apparatus according to an embodiment of the present invention.

5, the piezoelectric power generation unit 110 is installed on the road surface of the road 200 and converts impact energy such as pressure or vibration caused by the vehicle 300 running on the road 200 into electric energy, can do.

The piezoelectric power generating unit 110 may include a lower member 111, a piezoelectric element 112, a filler 113, and an upper member 114.

The lower member 111 is a base layer of the piezoelectric power generation unit 110 and may be installed at a distance spaced from the road surface of the road 200 by a predetermined distance.

The piezoelectric element 112 may be fixedly mounted on the upper surface of the lower member 111. The piezoelectric element 112 provided on the lower member 111 can be installed along the wheel locus of the vehicle 300 running on the road 200. [ The wheels of the vehicle 300 directly contact the road surface of the road 200. The efficiency of the piezoelectric power generation unit 110 can be improved by installing the piezoelectric elements 112 along the locus of the wheels of the vehicle 300 .

The filler 113 may be positioned between the upper member 114 and the lower member 111 to be in close contact with the piezoelectric element 112. The filler 113 can protect the piezoelectric element 112 from being damaged or detached from external physical impact.

The phase member 114 may be provided on the upper surface of the piezoelectric element 112 and may transmit impact energy generated when the upper surface of the upper member 114 contacts the wheel of the vehicle 300 to the piezoelectric element 112.

The upper member 114 may be installed at the same height as the road surface of the road 200 or at a position higher than the road surface of the road 200. [ When the upper member 114 is provided so as to protrude higher than the road surface of the road 200, a continuous impact can be applied by the wheels of the vehicle 300 passing through the upper member 114. Therefore, when the upper member 114 is installed so as to protrude above the road surface of the road 200, a relatively large impact energy can be generated compared with the case where the upper member 114 is installed at the same height as the road surface, More electric energy can be generated.
