Water injection system using lamppost for fine dust reduction and urban heat island mitigation}

The present invention relates to a water jet system using a street lamp pole, and more particularly, to a water jet system using a street lamp pole for reducing particulate matter and mitigating urban heat islands, which is configured to spray water directly from a street lamp pole.

Recently, the atmosphere in the metropolitan area is supported by various air pollution reduction policies, such as the expansion of supply of clean fuel and low-sulfur oil by the government, dissemination of low-emission vehicles, and the enactment of the "Special Act on Air Quality Improvement in the Metropolitan Area". CO), etc., is showing a tendency to improve the pollution status of developing countries.

However, the degree of pollution such as PM10 (fine dust having a diameter of about 10 µm) is gradually increasing or worsening, and the form of air pollution is being converted into an advanced country type. In particular, compared to major cities in the Organization for Economic Cooperation and Development (OECD), the concentration of fine dust in the metropolitan area of the Republic of Korea is 1.7 to 3.5 times higher, and is reported to be the lowest level. According to a report by the Korea-US Economic Research Institute (KEI) in 2002, it is estimated that the cost of damage caused by fine dust will reach about 10 trillion won, so it is time to take a more active policy when considering the public's health and social costs. .

On the other hand, the heat island phenomenon has emerged as a new social problem in the city center, and the heat island phenomenon refers to a phenomenon in which the temperature in the city center is higher than the surrounding area due to air pollution or artificial heat.

If you draw an isotherm that connects the temperature between the city center and the surrounding area, the high-temperature part of the city center is called a'heat island' because it appears similar to the island's contour line, and the heat island produces a greenhouse effect as if the entire city is surrounded by a greenhouse.

The geothermal heat of road pavement has emerged as one of the main factors of this heat island phenomenon. Since most of the roads that occupy 10 to 20% of the urban area are made of water-soluble pavement, it is possible to expect the latent heat transport by water's evaporative acid like soil or greenery. The reason is that there is no, the temperature is higher due to the black color of the pavement, and a large amount of infrared rays are emitted from the asphalt pavement.

In order to overcome the above-mentioned air pollution and heat island phenomenon, most domestic and foreign countries are carrying out water cleaning using a specially designed water cleaning vehicle, and the effect of water cleaning using a cleaning vehicle is partially effective. Is being reported.

However, in the case of water cleaning using a vehicle, it is inevitable to move to a certain water source to secure water. Considering that the average moving speed of a cleaning vehicle is 50 km/hr, it can be said that there is a lot of time to be invested in advance for cleaning. In addition, the average moving speed of the cleaning vehicle during cleaning is 12.5 km/hr, which is highly likely to interfere with the operation of other vehicles. In addition, the lower part of the vehicle parked on the road surface cannot be cleaned using the vehicle, which implies a variety of inconveniences that require input of prior personnel.

The sprinkler part 11 according to the present embodiment is characterized in that it comprises a rotating body 110 and an inclined plate 112.

Prior to the description of the sprinkler 11, according to the present embodiment, the supply line 12 is fixed to a fixing member 31 that is configured under the street lamp arm 3, as shown in FIG. , The supply line 12 is horizontally arranged with the street lamp arm 3 and the nozzle 120 configured at the end thereof is configured to face the end of the street lamp arm 3 where the street lamp is configured.

The rotating body 110, which is one configuration of the sprinkler 11, is coupled to the end of the supply line 12 as shown in FIG. 3, and passes through the inside of the supply line 12 for water injection. It can be configured to rotate automatically by the water pressure.

The rotating body 110 is configured to automatically rotate by the water pressure of the water passing through the supply line 12, and includes an inner ring portion 112, an outer ring portion 111, and a rotating fan 113. Can.

First, as the inner ring portion 112 has an outer diameter smaller than the inner diameter of the supply line 12 and is illustrated in FIG. 4, which is a cross-sectional view taken along line AA of FIG. 3, a circular first passage 114 is formed at the center. .

In addition, the outer ring portion 111 is a double pipe structure as shown in FIG. 4, and is configured to include the first pipe 111a inside and the second pipe 111b outside, wherein the first pipe ( The inner periphery of 111a) is coupled to the outer periphery of the inner ring portion 112 in a rotatable structure, and a second passage 115 is formed between the first pipe 111a and the second pipe 111b.

At this time, the inner ring portion 112 and the first tube (111a) is not shown in detail, but may be coupled to each other in a water bearing structure.

And the rotating fan 113 is disposed in a plurality of the second passage 115 to interconnect the first pipe (111a) and the second pipe (111b), passing through the supply line 12 in FIG. When water having a constant water pressure injected into the nozzle 120 hits the rotating fan 113, the outer ring portion 111 is rotated.

In addition, since the water passing through the rotating body 110 automatically rotates the outer ring portion 111 of the rotating body 110, the inclined plate 112 integrally fixed to the outer ring portion 111 also rotates while the nozzle 120 ) Is sprayed in multiple directions, such as up, down, left, and right, as shown in FIGS. 7A and 7B, so that it can be sprayed onto the road R in a wider range.

This is because the street lamp poles are generally spaced apart from each other, so that water cannot be sprayed on the entire road when spraying water only to the lower side of the street lamp poles. As described above, the rotating body 110 and the inclined plate 112 operate by the operation mechanism. Water will be sprayed over the entire road (R).

Meanwhile, FIGS. 6 to 7 illustrate an example in which the anti-return plate 117 is integrally coupled to the outer ring portion 111 of the rotating body 110, and the anti-reinforcing portion having a certain area is prevented. The plate 117 is integrally combined to prevent the water refracted by the inclined plate 112 from splashing to the side of the sidewalk, thereby reducing damage to pedestrians.

At this time, the anti-splash plate 117 is configured to be in the form of a plate so that the inclined plate 112 extends downward along a direction extending diagonally, as shown in FIG. It can be, but it is obvious that it can be configured in various other forms.

This is a water injection system according to the present invention is configured to be water sprayed only to the road side, as shown in Figure 1, in the above embodiment, the water sprayed through the nozzle 120 is refracted on the inclined plate 112 and injected to the road side When possible, a part of the water to be sprayed is likely to leak to the side of the delivery, so that it is possible to completely block it by providing the anti-skidding plate 117 as described above.

At this time, since the 판 prevention plate 117 is integrally configured with the outer ring portion 111, when the outer ring portion 111 rotates as in the above embodiment, it can rotate in conjunction therewith, as shown in FIG. 7A. When rotated 90° in the clockwise direction compared to FIG. 6, it is arranged to extend toward 270° in the clockwise direction, thereby blocking water that can be leaked to the side of the sidewalk. Also, as shown in FIG. When it is rotated by 90°, it is arranged to extend toward 270° counterclockwise correspondingly, so that water that can be splashed to the side of the sidewalk can be effectively blocked.

According to the above embodiments, the water injection system according to the present invention sprays water on the road surface, but since the spraying device 10 is configured in the street lamp column 1, water is sprayed at a certain height or higher. It is possible to effectively remove various pollutants such as fine dust and ultra fine dust in the atmosphere.

In addition, the water spraying system according to the present invention can directly lower the temperature of the road surface paved with asphalt during heat waves, thereby significantly reducing power consumption for cooling in the city, and managing trees due to water supply during heat or drought. Since it is possible to prevent the roadside trees from drying out and the like, a water spraying system that can effectively perform various functions can be implemented by using the existing infrastructure, that is, using a pre-installed street lamp (1) and a fire hydrant (20). It is possible to provide advantages that can significantly reduce the cost and time required for installation and maintenance.
