To do it.

본 고안을 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 3에서와 같이, 본 고안에 의한 제설장비를 갖는 도로방호시설물은 중앙분리대 또는 방음벽을 구성하는 콘크리트방호블록(10)에 배관매입홈(11)을 형성하고 상기 배관매입홈(11)에 노즐배관(20)을 매입 설치하며 상기 노즐배관(20)의 끝단에 제설(除雪)용 염수를 분사하기 위한 노즐(30)을 연결하되 도로의 노면을 향하도록 설치된다.As shown in Figures 1 to 3, road protection facilities having snow removal equipment according to the present invention forms a pipe embedded groove 11 in the concrete protection block 10 constituting a central separator or soundproof wall and the pipe embedded groove 11 The nozzle pipe 20 is installed in a buried and connected to the end of the nozzle pipe 20 to connect the nozzle 30 for injecting salt water for snow removal (除雪) to the road surface.

상기 노즐배관(20)은 염수공급탱크(40)에 연결된 메인배관(50)에서 분기되어 제설작업에 사용하기 위한 염수를 공급받도록 구성되며, 상기 메인배관(50)과 노즐배관(20)의 사이에는 모터밸브(60)가 설치된다.The nozzle pipe 20 is branched from the main pipe 50 connected to the salt water supply tank 40 is configured to receive the brine for use in snow removal, between the main pipe 50 and the nozzle pipe 20 The motor valve 60 is installed.

또한, 상기 모터밸브(60)의 아래에는 노즐(30)로 공급되는 염수가 일정한 압력 및 유량으로 공급될 수 있도록 균일 공급을 가능하게 하는 볼밸브(70)를 설치하여 사용함이 바람직하다.In addition, it is preferable to install and use a ball valve 70 below the motor valve 60 to enable uniform supply so that the brine supplied to the nozzle 30 can be supplied at a constant pressure and flow rate.

이때, 상기 모터밸브(60)나 볼밸브(70)는 노즐배관(20) 상에 설치되며, 상기 모터밸브(60)는 메인배관(50)을 통해 노즐배관(20)으로 유입되는 염수의 유량압력에 의해 개폐 및 개폐정도가 조절된다.At this time, the motor valve 60 or the ball valve 70 is installed on the nozzle pipe 20, the motor valve 60 is the flow rate of the brine flowing into the nozzle pipe 20 through the main pipe (50). Opening and closing degree is controlled by pressure.

상기 염수공급탱크(40)에 연결된 메인배관(50) 상에는 펌프(80)가 설치되고, 펌핑되어 공급되는 염수의 압력이 낮은 경우 출력된 염수를 염수공급탱크(40)로 바이패스할 수 있도록 바이패스밸브(90)가 설치된다.The pump 80 is installed on the main pipe 50 connected to the brine supply tank 40, and when the pressure of the brine supplied by the pump is low, the output brine can be bypassed to the brine supply tank 40. A pass valve 90 is installed.

상기 염수공급탱크(40)에 저장된 염수를 도로의 노면에 분사하기 위해 동작되는 모터밸브(60), 볼밸브(70), 펌프(80), 바이패스밸브(90)는 컨트롤부(미 도시됨)에 의해 동작 제어 및 동작대기상태를 갖도록 구성된다.The motor valve 60, the ball valve 70, the pump 80, and the bypass valve 90 which are operated to spray the brine stored in the brine supply tank 40 on the road surface are control units (not shown). It is configured to have an operation control and operation standby state by the).

상기 컨트롤부는 무선통신에 의해 원격 조정되도록 구성함이 바람직하며, 수동조작으로도 동작되게 한다.The control unit is preferably configured to be remotely controlled by wireless communication, and to be operated by manual operation.

상기 콘크리트방호블록(10)에는 노즐(30)이 설치되는 하측단부에 관통홀(12)을 형성하여 콘크리트방호블록(10)의 전후방을 향하도록 양측부에 노즐(30)이 설치되게 구성할 수도 있다.The concrete protection block 10 may be configured so that the nozzles 30 are installed at both sides to face the front and rear of the concrete protection block 10 by forming a through hole 12 at the lower end where the nozzle 30 is installed. have.

상기 염수공급탱크(40) 또는 메인배관(50)에는 히팅장치(미 도시됨)를 구비하여 노즐(30)로 공급되는 염수가 얼지 않도록 하며, 공급되어 분사되는 염수에 열량(熱量)을 갖게 함으로써 제설작업의 더욱 빠른 대응이 이루어질 수 있도록 구성함이 바람직하다.The salt water supply tank 40 or the main pipe 50 is provided with a heating device (not shown) so as not to freeze the salt water supplied to the nozzle 30, by having a calorie (熱量) in the supplied salt water It is desirable to configure so that a faster response of the snow removal operation can be made.

이러한 구성으로 이루어진 본 고안에 의한 제설장비를 갖는 도로방호시설물은 관리자나 운전자에 의해 원격 또는 수동으로 운전명령이 컨트롤부로 전달되면, 컨트롤부는 제설장비를 가동시킨다.The road protection facility having snow removal equipment according to the present invention having such a configuration, when a driving command is remotely or manually transmitted by a manager or a driver, the control unit operates snow removal equipment.

컨트롤부에 의한 제설장비의 가동은, 펌프(80)가 작동되고 염수공급탱크(40)에 있는 염수를 펌핑하여 메인배관(50)을 통해 노즐배관(20)으로 염수를 공급하게 되며, 노즐배관(20)을 통해 노즐(30)로 공급되는 염수는 노즐배관(20) 상에서 모터밸브(60)를 경유하여 유량 조절되고 볼밸브(70)에 의해 일정 압력 및 유량으로 분배되어 공급되어 도로 노면을 향하여 배치된 노즐(30)을 통해 분사된다.Operation of the snow removal equipment by the control unit, the pump 80 is operated and pumps the brine in the brine supply tank 40 to supply the brine to the nozzle pipe 20 through the main pipe 50, nozzle piping The brine supplied to the nozzle 30 through the 20 is flow rate controlled via the motor valve 60 on the nozzle pipe 20 and distributed by a constant pressure and flow rate by the ball valve 70 to supply the road road surface. It is sprayed through the nozzle 30 disposed toward.

노즐(30)을 통하여 도로 노면으로 분사되는 염수는 도로노면에 쌓이거나 쌓인 눈을 녹여 제거하게 되며, 히팅장치의 가동을 통해서 열량을 갖는 염수를 분사하게 되면 더욱 빠르게 제설작업을 수행할 수 있게 된다.The brine sprayed on the road surface through the nozzle 30 is removed by melting snow accumulated or accumulated on the road surface, and when the salt water having a calorie is injected through the operation of the heating device, snow removal can be performed more quickly. .

이때, 노즐(30)을 통한 도로 노면으로의 염수 분사는 컨트롤부에 의해 가동구간이 나누어져 실행될 수 있고 시간에 의한 동작제어나 염수의 소모량에 의한 동작제어 등 다양하게 제어될 수 있다.At this time, the salt water injection to the road surface through the nozzle 30 can be executed by the operation section is divided by the control unit can be variously controlled, such as the operation control by time or the operation control by the consumption of salt water.

또한, 노즐(30)이 연결되는 노즐배관(20)을 콘크리트방호블록(10)에 매입 처리함에 따라 돌출부위를 최소화 또는 없앨 수 있어 운행되는 차량과의 걸림 등 마찰이 없게 되며, 콘크리트방호블록(10)에 배관 등을 설치시 매입되므로 미관을 해치지 않는 유용함을 제공하게 된다.In addition, as the nozzle pipe 20 to which the nozzle 30 is connected is embedded into the concrete protection block 10, the protrusion part can be minimized or eliminated, so that there is no friction, such as a jam with a running vehicle, and the concrete protection block ( 10) Since it is purchased when installing the piping, etc. will provide a useful that does not harm the aesthetics.

상기한 본 고안의 제설장비를 갖는 도로방호시설물은 도로 또는 고속도로 상에 설치되므로 제설작업을 빠르게 수행할 수 있는 장점을 제공하고 눈에 의하여 차량의 소통이 정체되거나 지연 또는 마비되는 것을 매우 효과적으로 방지할 수 있으며, 도로 상에 설치된 시설물을 이용하므로 급작스럽게 내리는 눈에도 아주 빠르게 대처하여 제설작업을 수행할 수 있게 된다.The road protection facility having the snow removal equipment of the present invention is installed on a road or a highway, thus providing an advantage of performing snow removal quickly and effectively preventing traffic jams, delays, or paralysis by snow. It is possible to use the facilities installed on the road, so that it is possible to cope with snow very quickly to perform snow removal.

이에 따라, 차량의 소통을 가능하게 하는 도로 또는 고속도로의 제기능 발휘를 가능하게 한다.As a result, it is possible to exhibit a function of a road or a highway enabling communication of vehicles.

특히, 고속도로의 하이패스구간 등에 설치시에 더욱 유용하게 사용될 수 있으며, 제설작업의 빠른 대응을 가능하게 한다.In particular, it can be used more useful when installed in the high-pass section of the expressway, and enables quick response of snow removal operations.
