Road snow melting system using carbon induction heating element {ROAD SNOW MELTING SYSTEM USING CARBON INDUCTION HEATING ELEMENT}

The present invention is a road snow melting system using a carbon induction heating element, and more particularly, in order to prevent vehicle congestion and vehicle slip accidents caused by snowfall and road ice in winter, By cutting and embedding electric heating wires and heat conductors, it is possible to quickly transfer the heating heat to the road surface through the heat conductor, and using IoT technology to enable remote wireless communication using an app in a Wi-Fi environment to prevent vehicle accidents. It is related to a road melting system using a carbon induction heating element to prevent it.

Road Snow Melting System is an efficient snow removal system for vulnerable points as a means of securing traffic safety in areas where traffic accidents are expected, such as steep slopes of roads, entrance and exit routes of APT parking lots, entrances and exits of tunnels during winter snowfall and freezing. In order to build a system, a heating wire or heating pipe is buried at a certain depth under the road pavement to automatically detect temperature and humidity and supply power when it snows in winter or when road freezing occurs due to temperature difference.

In general, when snow or freezing occurs on the road, vehicle slip is prevented through physical removal through snow removal or calcium chloride, thereby preventing the occurrence of accidents. However, in the case of such a snow removal method, the snow removal work must be performed immediately during snowfall, and when the snow continues for a long time, there is an inconvenience that the worker must always wait to perform the snow removal work.

In addition, excessive use of snow removal agent not only corrodes the vehicle, but also becomes a factor that causes environmental pollution by turning into fine dust as it dries. Calcium chloride is also a cause of potholes in which the road surface is pitted, which is one of the main causes of road accidents. Calcium chloride not only melts snow, but also lowers the bonding strength of asphalt. Roads that have become soft like this are easily pitted under the load of a running vehicle.

A number of road melting devices as a snow melting system to solve this problem have been disclosed. In this way, as in Korean Patent No. 10-1898727, a heat dissipation pipe is buried under the road surface and a heat source fluid is passed through the heat dissipation pipe. There is a method in which the heat generated by the fluid is transferred to the road surface.

However, in this case, water is used as a fluid, and accessory members such as a radiator and boiler are required as a heating device to heat such fluid, so it is not reasonable in terms of installation area and installation cost. There is a possibility that problems such as freezing of the surface due to temperature difference on the surface may occur. In addition, there is a problem in that the heat dissipation tube disposed on the pavement layer of the road is subjected to pressure and impact while passing through a high-load dump truck, and the heat dissipation tube is greatly damaged.

To this end, a road melting device, which installs a snow melting device on a road by burying a heating wire and using the high-temperature heat generated from the heating wire as a medium, has already been widely installed and operated.

The existing electric heating wire burial method is a method of installing an electric heating wire on the top of the base pavement of a cement or asphalt pavement, and finishing it with an overlaid pavement such as mortar. This method is in contact with the load of the equipment during the overlaid pavement work. The electric heating wires paved under the pavement may be damaged by the like, and the thickness of the pavement layer is not constant, so there is a problem in that road damage accompanied by cracks may occur due to shock and vibration of a vehicle passing through the road.

In general, it is a method of installing electric heating wires on the top of the base pavement of an already formed cement concrete or asphalt concrete pavement, and finishing it with an overlying (surface layer) pavement.In this case, under the pavement due to equipment load and contact, etc. There is a serious problem in that the installed electric heating wire may be short-circuited or damaged.

In other words, when a heavy-duty dump truck is driven on the road from time to time, the amount of impact in the vertical direction according to the load is large and damage to the buried heating element occurs. This is self-evident in the light of the road environment.

In addition, for this purpose, a snowmelting system in which the outer shell is made of cylindrical metal is disclosed.For example, the outer shell is constructed of metal material by embedding it during road snow melting work such as asphalt or concrete using MI heating cables. It is a system that uses HDPE (high-density polyethylene) as the outer shell to provide strength that can overcome the load of the vehicle in the state.

However, even in this case, there is a problem in having an advantage in thermal properties such as thermal conductivity that improves thermal efficiency, only for protecting the heating element from accumulated external load impact.

An object of the present invention to solve the above-described conventional problems is to implement a system capable of automatic remote control in combination with an IoT system to operate a carbon-induced heating system at a required place and time, thereby reducing the amount of power required and automatically melting snow during heavy snowfall and freezing. It is to prevent traffic accidents in advance by preventing icing.

In addition, as a tertiary cover structure, a certain amount of carbon black is added to the secondary and tertiary coatings to increase the thermal conductivity, and a carbon steel pipe with excellent induction heating efficiency and mechanical strength is composed of an induction heating tube, which is an external structure of the heating element, to increase the height of the road. By securing structural stability that can protect the buried heating element from heavy progressive shock, the life of the buried carbon induction heating element is significantly increased, and the high heat source by the heating element is more easily conducted to the inside and outside of the carbon steel pipe, thereby enhancing the efficiency of induction heating. Has another purpose.

Road melting and snow system according to the present invention for solving the above-described conventional problems and achieving the object of the present invention, in the road melting and snow system using a heating element, a carbon steel pipe as an outer jacket is buried at a depth of 60 to 80 mm from the ground surface. , As the inside of the carbon steel pipe, a nickel chromium heating wire which is a heating conductor sequentially from the center to the outside, and a carbon induction heating element constructed by internally installing a primary insulator containing carbon black and a secondary insulator containing carbon black are used, The carbon induction heating element is buried by cutting 2 to 4 lines at intervals of 200 to 300 mm by cutting the road, but as the cutting method of the road, after removing the surface asphalt or concrete, and using a dry cutter inserting a diamond blade into the base layer, the width It uses a dry suction method in which dust or foreign matter generated by a vacuum suction device is attached around the diamond blade and removed by a constant cutting to 20mm and a depth of 60~80mm, and is used for embedding the carbon induction heating element. After installing a pull box and a splicing box, forming a plurality of connection holes in the center of the longitudinal side of the pull box and splicing box, inserting a carbon steel pipe into the connection hole, and the carbon steel pipe facing the connection hole By welding a part, the carbon steel pipe is horizontally fixed to a certain depth from the ground, and the nickel chromium heating wire and the outer circumference of the primary and secondary insulators are wrapped inside the carbon steel pipe protruding into one of the full boxes for a predetermined length. It is installed and managed by pushing or removing the protecting yobi wire to facilitate repair for each section.The carbon steel pipe contains 0.13 to 0.20% carbon, and the primary insulator is made of Teflon-made fluororesin and carbon black. It is composed by mixing, but the carbon black content is 22.80 ~ 23.25%, and the secondary insulator is characterized in that the thermoplastic elastomer containing 24.00 ~ 24.20% carbon black.

Hereinafter, a road snow melting system using a carbon induction heating element according to the present invention will be described in detail with reference to the accompanying drawings.

First, the heating system that uses Joule heat by the current induced in the inner surface of the steel pipe as a heat source is called an induction heating system, and the steel pipe is called an induction heating tube, and the electric wire is called an induced current wire. Hereinafter, the induction heating tube is called a carbon steel tube and the induction current wire is called a heating line (nickel chromium heating line) according to an embodiment of the present invention.

And, in the snow melting system of the road snow melting system will be described in the order of the work process according to an embodiment of the present invention.

First, referring to FIG. 1, when the structure of the carbon induction heating element 300 according to the present invention is described, the carbon induction heating element 300 is a carbon steel pipe having a high thermal conductivity of 0.13 to 0,20% as an outer jacket ( 350) is buried to a depth of 60mm to 80mm, and inside the carbon steel pipe 350, the nickel chromium heating wire 310, which is a heating conductor, from the center of the inside of the cylindrical structure, protects the covering and protects the heating element by withstanding at 250°C. Disclosed is a structure in which a primary insulator 320 and a secondary insulator 330 for maximizing efficiency are sequentially installed in an external radial direction.

In this case, the heating wire 310 and the insulators 3210 and 330 are configured with an internal insertion structure of the carbon steel pipe 350 in the form of a yobi wire 340, so that the process of introducing and drawing into the carbon steel pipe 350 is easier. It is desirable to do it. Hereinafter, a structure including the heating line 310 and the primary and secondary insulators 320 and 330 will be referred to as a yobi line 340 for convenience.

The carbon steel pipe 350 is a pipe made of carbon steel, which is an alloy of carbon and iron, and is used for heat transfer inside and outside the pipe, and preferably a carbon steel pipe 350 having a carbon content of 0.13 to 0,20%. By utilizing the induction heating method by the nickel chromium heating wire 310, the heat transfer efficiency of the internal nickel chromium heating wire 310 is prevented from deteriorating due to the external environment, and thermal conductivity, electrical conductivity, and high strength characteristics, which are the characteristics of carbon, are prevented. Through this, the internal nickel chromium heating wire 310 can be protected and the efficiency of transferring the high-temperature heat generated therefrom can be improved.

The properties of the carbon steel pipe 350 are basically determined according to the carbon composition, and even if the amount of carbon is constant, the properties of the carbon steel pipe 350 change remarkably depending on the processing conditions or heat treatment conditions. As for the electrochemical properties of the carbon steel pipe 350, specific gravity, coefficient of thermal expansion, and thermal conductivity decrease as the amount of carbon increases, but specific heat, electrical resistance, and coercive force increase. In addition, corrosion resistance of carbon steel pipes decreases as the amount of carbon increases, and corrosion resistance is improved when a small amount of copper (Cu) is added.

A brief look at the mechanical properties of the carbon steel pipe 350 at room temperature increases the tensile strength and hardness according to the carbon content, and the elongation and cross-sectional reduction rate decrease according to the amount of carbon. That is, the higher the carbon content, the harder the carbon steel, but the more fragile it becomes.

Considering the characteristics of the carbon steel pipe 350, in the present invention, in order to perform the thermal conductivity characteristic according to the function of the induction heating tube and the protective tube function to protect the internal heating line, the outer diameter of the carbon induction heating element is approximately 20 mm. In forming a carbon steel pipe having a carbon content, it is preferable to have a carbon content of 0.13 to 0.20%, which is a low carbon steel standard optimized for welding.

The carbon induction heating element 300 according to the present invention having such a basic configuration is a series-type heating cable, insulated with an insulator such as fluorine resin or silicone rubber on a resistance heating wire made by twisting several strands of nickel or chromium alloy wire 310 as a resistance wire. After that, it is a cable that is covered (320, 330) with plastics (fluorine resin, heat-resistant rubber, vinyl chloride, etc.) having mechanical strength on the outer layer. It is characterized as a heating wire that is harmless to the human body by blocking almost 99% of electromagnetic waves. .

If the heating cable structure 300 is divided with reference to Fig. 1, in the innermost center of the cylindrical heating element structure having a predetermined diameter, a nickel chromium heating wire 310, which is a heating conductor widely used as a general heating wire, is configured. , It can be seen that the primary and secondary insulators 320 and 330 surrounding the outer circumferential surface of the nickel chromium heating wire 310 are formed in an external radial direction.

These insulators 320 and 330 should be made of a material that withstands high temperatures to have heat resistance, and this is a configuration for preventing electric shock from occurring even if the wire is buried in the ground or touched.

Preferably, the primary insulator is composed of a mixture of Teflon-made fluororesin and carbon black, and the secondary insulator is a thermoplastic elastomer (TPE) material.

In this case, the primary insulator 320 is composed of a mixture of a fluororesin made of Teflon and carbon black, but the carbon content is in the range of 22.80 to 23.25%, and the secondary insulator 330 is carbon added to the covering raw material. It is preferable to use a thermoplastic elastomer (TPE) having a content of 24 to 24.20%.

More preferably, the primary insulator 320 is composed of 23.06%, the secondary insulator 330 is composed of 24.08% carbon content%. As shown in Fig. 8, this is a value confirmed based on the test report of March 23, 2020 by requesting a component analysis from the Korea Institute of Quality Tests on March 10, 2020, and this is an empirical value that can increase the heat conduction efficiency of an insulator. It is the result. As the resistance value of the nickel chromium heating line 310, which is the heating line, increases, the resulting electricity cost increases. In order to save this, it is very important to keep the heating temperature completely transmitted to the road surface. To this end, a certain amount of carbon black was mixed in the primary and secondary insulators (320, 330) to have the most excellent electrical conductivity, and the carbon steel pipe (350), which is an induction heating tube, was also manufactured to have a high carbon content with high induction heating efficiency. .

Teflon material has heat resistance that can withstand a temperature of 250°C and is also used for conductive coatings for antistatic purposes, and since it has very high insulation, low loss rate, and excellent surface resistivity over a wide frequency band, this material was used as an insulator. In addition, fluororesin has excellent properties in heat resistance, chemical resistance, weather resistance, and electrical properties when compared to the riding molecular material.

A high-molecular fluororesin that can increase electrical conductivity and strength by mixing carbon black with a fluororesin made of Teflon having such characteristics, that is, by uniformly mixing the carbon material through interfacial interaction with fluorine resin particles-carbon black It is possible to obtain and use such a polymeric carbon composite material by molding using a hot forming apparatus, and the coating, which is the primary insulator 320 made in this way, has a property of very high thermal conductivity.

Thermoplastic elastomer (TPE) is a high molecular material with properties that can be processed thermally and has rubber properties by crosslinking. It is a material with excellent elasticity of rubber and processability of thermoplastic resin. It is suitable for existing PP/EPDM thermoplastic elastomers. Compared to that, it has excellent oil resistance, weather resistance, and fatigue resistance, and thus, it is composed of a material of the secondary insulator 330 in the present invention, and has high thermal conductivity.

Next, the road cutting process for burying the carbon induction heating element structure under the road surface will be described. First, the carbon induction heating element 300 is constructed by cutting 2 to 4 lines at intervals of 200 to 300 mm, and the installation length Cuts the road surface along the road length to which the heating element structure is applied.

Next, a road cutting method of forming a buried groove to a predetermined depth at an installation location on a road surface as a pre-process for the burial of the carbon induction heating element 300 will be described as follows.

As for the road cutting method, after removing the asphalt or concrete from the surface layer when cutting the located road, using a cutting machine 400 inserting a 20 mm diamond blade 410 into the base layer, cut it uniformly into a width of 20 mm and a depth of 60 to 80 mm, and the diamond blade It is preferable to use a dry suction method in which dust or foreign matter generated by attaching a vacuum suction device 420 to the periphery of 410 is sucked and removed.

When looking at a cross-sectional view of a general road pavement, concrete or asphalt is cured on the road surface through which a vehicle passes, and a base layer and a road plate are sequentially stacked from the top to the lower portion thereof.In the present invention, the carbon induction heating element 300 buried When cutting the road in the area where) is located, first remove the top layer of asphalt or concrete, and then use a dry cutter 400 with the diamond blade 410 inserted into the upper surface of the lower base layer to a fixed width of 20 mm and a depth of 60 to 80 mm. Cut it.

To this end, as shown in FIG. 3, after inserting a 20mm diamond blade 410 according to the cutting width, power is applied to the cutting machine 400, and then cut outside the diamond blade 410 for dust treatment when cutting by a driving device. A shatterproof cover 430 is covered to prevent dust generated during scattering to the outside, and a vacuum hose 422 is attached to one side of the scattering prevention cover 430 so that the diamond blade 410 cuts the road cut part. In this case, dust generated during the cutting process is sucked in according to the power drive of the external vacuum suction device 421 to prevent and collect dust from the outside, so that an environmentally friendly road cutting process can be performed. The configuration shown in FIG. 3 is for showing general components, and the configuration and shape of the dry cutter 400 can be variously applied.

By using such a dry method, it is possible to improve sludge generation, difficulty in removing foreign substances, and difficulty in sequential work due to freezing of water, which are problems when using a wet rod cutter as described above.

In a similar manner, the other end of the carbon steel pipe 350 is inserted into the connection hole 179 formed in the center of the splicing box 121, the resin side surface portion 121b, and welded. This method is equally applied to the structure in which the carbon steel pipe 350 is inserted into the splicing box 120, the other side connection hole 179 and the other side full box connection hole 178.

In addition, the plurality of full boxes 110 and splicing boxes 120 are connected and accommodated in the form of a yobi wire 340 without a carbon steel pipe as a protective pipe or a nickel chrome heating wire 310 as a heating element, so that the snow melting system When a defect occurs for each part of the installation road, the electric wire is pulled out and cut only in the problem part, and then the heating wire 310 is reattached, or the heating wire buried length is stretched or stacked as needed so that it can respond appropriately to the change in length. desirable.

In addition, in the present invention, the operation of the field visit system after such monitoring is not limited, but the administrator installs a Wi-Fi-based smart plug so that remote automatic control is possible through a separate app, and the heating element 300 is registered in advance so that the vehicle In order to prevent slipping accidents in advance, road facility managers provide an efficient system by enabling automatic remote control through the IoT monitoring (500) system.

Preferably, such a remote control function constitutes a control system that enables a disaster situation room manager to use a method of utilizing a smart plug system linked thereto by using an app in preparation for an emergency in a disaster situation.

Another function is to provide a road current situation screen and road current status information so that the driver who has installed a separate app in the danger zone where freezing is expected can check the road condition in advance, so that the driver bypasses or accidents such as speed reduction. The system may be configured to prevent vehicle sliding accidents in advance by having preventive vehicle movements.

In addition, it is desirable to implement an IoT-based control system 500 capable of interactive communication by allowing a vehicle driver who has passed the corresponding road to feed back the current road surface state of the road and transmit it in real time to other drivers and system managers. In this case, for vehicle safety, the touch input screen is composed of A/B/C grades, which are safety/careful/dangerous grades, rather than text input method, so that the driver can easily transmit the current road surface condition information. More preferable.

In addition, by establishing an integrated computer network 540 that integrates and manages information on the area where the snow melting system is installed, the IoT monitoring system 500 and the remote control system 530 are applied, so that a more comprehensive and efficient computer network can be utilized. It will also be possible to configure.
