A pull-out type buried underground field monitoring control panel with a flood double safety structure, the control panel comprising:
- an enclosure 10 formed and buried in the ground in a shape of a housing having a top side of an open shape and opened or closed by a cover 11, and installed to be positioned on the same horizontal line as the ground;
- a lower support 20 located on a lower side of an accommodation space 19 of the enclosure 10, formed in a “Π” shape with a closed top side, and vertically moved up and down by a lifting member 81 provided on a bottom side of the enclosure 10;
- an upright panel 30 fixedly provided in a form of a vertical panel on a top of the lower support 20, wherein an electronic operating device of the control panel including a controller is coupled to a lateral side of the upright panel 30;
- guide bars 51 vertically provided to be spaced apart from each other on both sides of the upright panel 30 in a horizontal length direction;
- an inner box 60 provided to slide up and down in the vertical direction along the guide bars 51, wherein as the inner box 60 vertically moves downward along the guide bars 51, the upright panel 30 is protected inside an accommodation unit 60a of the inner box 60, and as the inner box 60 vertically moves upward along the guide bars 51, the upright panel 30 is exposed from the accommodation unit 60a of the inner box 60 so that handling and maintenance of the electronic operating device coupled to the lateral side of the upright panel 30 are possible, and as the inner box 60 is formed in a “Π” shape having an open bottom side and closed lateral and top sides to surround an outer side of the lower support 20 while descending so that an air pocket is formed inside the accommodation unit 60a, inflow of rainwater or groundwater into the inner box 60 is prevented in a state where the inner box 60 has moved to the lower side, and therefore, the electronic operating device of the control panel coupled to the lateral side of the upright panel 30 is protected from moisture or water;
- a protection panel 99 vertically installed on the lower support 20 inside the inner box 60 to protect the lateral side of the upright panel 30, wherein an upper end of the protection panel 99 is positioned to be higher than an upper end of the upright panel 30;
- and
- an air discharge means 90 fixedly provided inside the upper end of the protection panel 99 to push out the water flowing in from a bottom side of the inner box 60 with air pressure when flooding occurs inside the inner box 60, wherein the air discharge means 90 includes an air compression tank 91 for storing compressed air, a pressure reducer 92 connected to the inlet and outlet side of the air compression tank 91, a solenoid valve 96 connected to the pressure reducer 92 through a hose 93, a flood detection sensor 98 connected to an electric wire 97 to transfer a flood detection signal to the solenoid valve 96, and an injection nozzle 96a connected to the bottom side of the solenoid valve 96 to inject and discharge air toward the inside of the inner box 60, wherein the inner box 60 is raised or lowered by an operation of rods 76 of cylinders 75 by connecting the cylinders 75 in a direction of diagonally crossing hinges 71 to 74 up and down while lower hinges 71 and 72 are provided on both sides of the rear side wall of the lower support 20, and upper hinges 73 and 74 are provided on both sides of the upper portion on the rear side wall of the inner box 60,
- wherein the protection panel 99 is formed in a “⊏” shape having open top and front sides and closed rear and both lateral sides, a horizontal support 95 connecting upper end portions on both sides of the protection panel 99 is provided, the air compression tank 91 is fixedly provided on the horizontal support 95, the solenoid valve 96 is fixed on the upright panel 30 tightly attached to a front side of the protection panel 99, and the flood detection sensor 98 is provided to be spaced apart from the bottom side of an upper plate 29 of the lower support 20.
