Description

Road sprinkler with self-water intake function {ROAD SPRINKLER WITH SELF WATER- INTAKE FUNCTION}

The disclosed content relates to a road sprinkler device that is installed in the center of a road or at a curb and has a self-watering function that lowers the temperature of the road by self-watering and spraying purified water onto a high-temperature road.

Unless otherwise indicated herein, the matters described in this identification are not prior art to the claims of this application, and are not admitted to be prior art by virtue of being described in this identification.

Recently, due to urban warming due to environmental pollution, a heat island phenomenon has occurred in which the temperature of urban areas is higher than that of nearby areas. In urban areas, water is periodically sprinkled on roads using sprinkler trucks to lower the temperature of the roads.

However, water sprinkler trucks are difficult to operate when traffic is blocked on the road, and operating a sprinkler truck requires costs such as labor costs, which poses a problem in being a sustainable solution to the heat island phenomenon.

Accordingly, road sprinkler devices that spray water on the road unmanned are being proposed.

As an example of such an unmanned road sprinkler device, Republic of Korea Patent Registration No. 10-2451602 (registered on September 30, 2022) includes a spray nozzle installed at the curb of the road, and the outlet of the spray nozzle is normally closed, but open during spraying. It is characterized in that it is configured with an opening and closing means as much as possible, and the opening and closing means includes, for example, a door that blocks the end of the spray nozzle so as to block the outlet of the spray nozzle, and a hinge part installed to rotate the door from one end of the spray nozzle. It consists of an elastic member installed to block the door from the hinge portion to the end of the spray nozzle, and the outlet of the spray nozzle is normally blocked by the elastic member, but during spraying, the door is closed by the spray pressure. A road sprinkler device for boundary stones is disclosed, which is characterized in that the exit is opened by rotating around a hinge portion.

In addition, Republic of Korea Patent Registration No. 10-2238273 (registered on April 5, 2021) includes a water spray pipe embedded in a road, a water spray valve branched from the water spray pipe, and installed in a groove formed at a certain depth in the road and connected to the water spray pipe. It includes a protective pipe arranged to be grounded on the upper surface, and a disk-shaped marker fixed to the upper end of the protective pipe so as to protrude from the surface of the road, and passes through the center of the marker in an upward and downward direction depending on the water pressure of the water supplied to the water spray pipe. A road sprinkler device is disclosed in which a spray nozzle that appears and retracts is installed and at least one sprinkler hole is formed on a side of the spray nozzle.

However, the unmanned road sprinklers described above had a problem in that purified water had to be supplied to the sprinklers periodically.

As an example of a road sprinkler device with a self-water intake function in which water is taken from the road sprinkler device itself, Republic of Korea Patent Registration No. 10-2232052 (registered on March 19, 2021) includes a water source collection tank capable of collecting water from the sprinkler source; a spray nozzle that causes raw water from the spray source collection tank to be sprayed onto the road surface, a pump that supplies raw water from the spray source collection tank to the spray nozzle, and a device installed between the pump and the spray nozzle to filter foreign substances contained in the raw water. A road sprinkler device is disclosed, which includes a filter and a sterilizer installed between the filter and the spray nozzle to sterilize and disinfect malodorous substances contained in treated water filtered by the filter.

However, the conventional road sprinkler device with a self-water intake function as described above collects sewage or rainwater and purifies it through methods such as filtration, but the problem is that a complicated device is required to purify the water to be sprayed and it is expensive. It still existed.
