It relates to a smart information marker for information provision and management of underground facilities with improved efficiency for removing odors and harmful gases.

In general, various underground facilities (seven underground facilities) such as water supply pipes, sewer pipes, gas pipes, high-voltage cables, communication cables, oil pipelines, and heating pipes are buried under the road (underground), and the underground facilities are usually within 2m. It is buried in various depths from buried to several meters, and it is often damaged by various constructions because the buried depth of these underground facilities is not easily known.

For example, when a gas pipe is damaged when performing road construction, excavation construction, electric construction, water construction, or cable construction, not only property damage, but also personal injury is caused, and damage to the water pipe causes a disruption in water supply and damage to the communication cable. Silver causes communication disruption and paralysis in government offices / corporations / banks, and breakage of high-voltage cables causes huge damage such as power outages and plant shutdowns.

The management of the underground facilities only maintains the design drawings after sales and installation, and the actual construction is not well checked and managed.

For example, in some cases, it may not be possible to accurately check information such as the manufacturing date, manufacturer and condition of underground facilities, and in most cases, it is not possible to know whether or not the product used for construction is a recyclable or used product. .

In addition, there is a lack of a system that can accurately manage product inventory, movement paths, and storage conditions, and it is also unknown whether the design drawings and actual construction locations and specifications are consistent.

Therefore, it is impossible to confirm until the location is directly parsed, and there is an urgent need for a comprehensive management system that can easily input and confirm the information of these underground facilities.

In addition, information that has been changed after installation of underground facilities is managed in a way that is recorded on the management ledger rather than on-site or related underground facilities, and is not properly used due to neglect of management. There are many problems such as time and cost.

In particular, in the case of water and sewage management, it is mainly carried out through manholes. However, there are cases where workers suffocate after breathing due to odor and harmful gas in manholes, and countermeasures are required.

The marker unit 1 according to the present invention is installed in the manhole cover 110 of the manhole 100, as illustrated in FIG. 3.

At this time, a gas detection sensor SEN is electrically connected to the controller 11 of the marker unit 1, and the gas detection sensor SEN is manhole 100 in a state spaced apart from the marker unit 1 by a predetermined distance. It is arranged inside and is configured to detect the concentration of harmful gas (eg, methane, carbon dioxide, etc.) inside the manhole 100 and transmit the detection result to the controller 11.

And, inside the manhole 100, the odor removal water supply pipe 210 is piped to the opposite surface where the ladder 120 is installed, and the odor removal water injection nozzle 220 is installed at the end of the odor removal water supply pipe 210. It is configured to spray odor removal water in the radial direction.

In addition, an inlet pipe (P1) and an outlet pipe (P2) among sewage pipes are connected to the lower sides of the manhole (100), and the inlet pipe (P1) is piped higher than the outlet pipe (P2), and then the lower side is an outlet pipe. It is configured to be able to discharge sewage very smoothly by being configured to be rounded toward (P2).

In particular, the end portion of the inlet pipe (P1) is provided with a flap (F) so that it is closed when there is no discharge of sewage to minimize the occurrence of odor.

In this case, the flap (F) can be easily constructed by using a torsion spring that is always repressed in the direction to be closed.

Meanwhile, the odor removal water supply pipe 210 penetrates the manhole 100 in the lateral direction and is piped to the outside of the manhole 100, and is connected to the odor removal water tank 200 embedded in the outside of the manhole 100.

In addition, an underwater cryogenic plasma generator 240 is installed at the upper end of the malodor removal water tank 200, and a water supply pipe (not shown) drawn from a water pipe is connected to the malodor removal water tank 200 to reach a certain level. It is implemented in a known manner (such as a bure) to automatically cut off the supply and supply it again when the water level drops. If there is no water pipe, it can be configured to be supplied through a water pump separately.

The underwater cryogenic plasma generator 240 is a generator housing 242 that is assembled and fixed to the top of the malodor removal water tank 200, and the cylindrical insulator 244 embedded in the generator housing 242, as illustrated in FIG. ), A cylindrical cathode fastener 246 fixed to the lower surface of the insulator 244 and an air pipe connected to a portion of the outer circumferential surface of the insulator 244 to supply air into the insulator 244 (AP) ), The negative electrode (-) connected to the negative electrode fastener 246 and the positive electrode extending through the insulator 244 and the negative electrode fastener 246 to the malodor removal water tank 200 and immersed in the malodor removal water. It includes (+), the positive electrode (+) and the negative electrode (-) is connected to a commercial power source, and is controlled by the controller 11 so that electricity is supplied only when necessary.

In addition, the air pipe AP is configured to communicate with the inside of the manhole 100, and is configured to allow air to flow naturally.

Therefore, the air generated naturally through the air pipe AP flows toward the cathode fastener 246 from inside the insulator 244, thereby increasing the plasma generation efficiency.

In other words, the discharge efficiency is increased by allowing air, ie, oxygen, to exist between the discharge electrodes.

Here, the low temperature plasma in water is a plasma sterilization effect while the current is discharged in water in a low temperature state, and the water molecule is bundled with various kinds of radicals including hydrogen ions, oxygen ions, and hydroxyl radicals by low voltage low temperature plasma by underwater discharge. In particular, hydroxyl radicals have strong disinfecting and odor removal functions, and the changed sterilizing water is immediately sprayed and supplied as a pollutant to enhance the sterilization and sterilization effect.

And, after a certain period of time is reduced to water again, it is possible to create a safe and eco-friendly sterilization, odor removal structure without secondary pollution.

Moreover, when the plasma is generated, the micro-nano bubbles generated in water continuously generate white bubbles, and while the nanobubbles come into contact with contaminants, they sterilize and destroy odors and fungi caused by rupture to remove odors and realize strong sterilization. It comes to me.

That is, when a voltage is applied, discharge occurs between the positive electrode (+) and the negative electrode (-) to generate a low temperature plasma, which decomposes water to generate a number of radicals including hydrogen ions and oxygen ions.

At this time, the controller 11 operates the supply pump 230 to spray the sterilized water into the manhole 100 to sterilize it, thereby removing odor and decomposing in the process to suppress and remove methane generation.

Therefore, it is possible to remove environmentally friendly odors without using chemicals.
