The present application claims the benefit of Korean Patent Application No. 10-2021-0189190 filed in the Korean Intellectual Property Office on Dec. 28, 2021, the entire contents of which are incorporated herein by reference.
The present invention relates to a pull-out type buried underground field monitoring control panel with a flood double safety structure, and more specifically, a pull-out type buried underground field monitoring control panel with a flood double safety structure, which allows to control in a pull-out type manner by burying a control panel for controlling traffic lights, street lights, or water supply pipes in the ground, protect various types of electronic devices from moisture or water in the ground using a double sealing structure based on an air pocket principle, and have a double safety structure against flooding by generating internal pressure at a dangerous time point and applying the pressure to the water flowing into the inner box to push it out of the inner box although the air pocket function is degraded as an abnormal condition occurs in the structure of a “Π” shape due to long-time flooding.
Generally, a control panel is a device that comprehensively manages and operates various installed electrical facilities, air conditioning facilities, pump facilities, and the like, and is mainly used to control street lights, traffic lights, water supply pressure pumps, drainage pumps, flow meters, and the like. Such a control panel is generally installed on the ground, i.e., on the road, such as a roadside or the like in downtown, in order to prevent flood by rainwater and for the purpose of maintenance.
However, such a control panel installed on the road or on the ground considerably impairs the aesthetics or landscape of a city primarily and may cause traffic disturbances of pedestrians or vehicles. In addition, since control panels are mainly installed on the road or on the ground, it is highly worried that water such as rainwater or the like may infiltrate into the electrical or electronic equipment installed in the control panel, and accordingly, there is a problem in that safety accidents such as electric shock to pedestrians, as well as serious failures of the control panel itself, may occur at any time.
Although a method of burying the control panels under the ground, rather than on the ground, has been proposed recently to solve this problem, control panels of a method of burying underground suggested until present also do not completely block infiltration of water such as rainwater, groundwater or the like, and therefore, it is difficult to reach the stage of practical use.
Accordingly, the applicant of the present invention has proposed a pull-out type buried underground control panel using an air pocket principle through Korean Patent Registration No. 10-2117887, and it is intended to propose a field monitoring control panel having a double safety structure in preparation for flood safety.

Referring to
For implementation of the present invention, first, as shown in
The cover 11 is generally manufactured by casting, and although not shown, it is preferable to form a through hole on the cover 11, install an antenna capable of communicating with the outside in the through hole, and then fill epoxy around the antenna in the through hole so that the antenna is embedded therein. At this point, the antenna is configured to be electrically connected to the controller coupled to the lateral side of an upright panel 30 described below to allow communication from the outside of the control panel.
In addition, various synthetic resin materials may be used in addition to the epoxy filled in the through hole, and it is preferable that the through hole is formed in a wide-top narrow-bottom shape to have a bearing capacity with respect to the load of the epoxy and the antenna, in addition to stable seating of the epoxy.
A lower support 20 is provided on the lower side of the accommodation space 19 of the enclosure 10. The lower support 20 is configured to vertically move up and down by a lifting member 81 provided on the bottom side of the enclosure 10 as shown in
In addition, as shown in
On the other hand, as shown in
In addition, guide bars 51 are vertically provided to be spaced apart from each other on both sides in the horizontal length direction of the upright panel 30, and an inner box 60 is provided to slide up and down in the vertical direction along the guide bars 51.
The inner box 60 is provided to prevent inflow of moisture or water into the electronic operating device including the controller coupled to the upright panel 30, i.e., to protect the electronic operating device from moisture or water, and more specifically, as shown in
The inner box 60 is formed in a “Π” shape with an open bottom side and closed lateral and top sides, i.e., in the shape of a cup upside down, so that an air pocket is formed inside the accommodation unit 60a.
At this point, as for the elevating operation of the inner box 60, it is preferable to configure, as shown in
The air pocket function may be strengthened by the structure of the inner box 60 and the lower support 20. For this purpose, a side wall 21 of the lower support 20 is formed to be 10 to 25 Cm to prevent water or moisture from flowing into the side wall 21 of the lower support 20 from the outside of the inner box 60, and as another embodiment, the side wall 21 of the lower support 20 is formed of, as shown in
At this point, when a horizontal side wall 21e is further formed between the lower side wall 21a and the inclined side wall 21b as shown in
In addition, as a modified embodiment for further strengthening the air pocket function generated by the structure of the inner box 60 and the lower support 20, although not shown, a protrusion and depression structure of a thread form may be formed on the tightly attached sides of the extended side wall 21c and the side wall 61 facing each other so that the extended side wall 21c and the side wall 61 may be alternately and tightly attached to each other.

The air compression tank 91 is an embodiment, and although it will vary according to the amount of water flowing into the inner box 60 including the lower support 20, when the water flows in within an expected normal range, it is preferable to use an air compression tank 91 filled with air as much as to withstand inflow of water for at least 6 to 24 hours, and since a maintenance work is performed when a manager (repair worker) arrives within the 6 to 24 hours, an air compression tank 91 filled with air as much as an amount that can secure the time until the manager arrives should be used.
Then, the solenoid valve 96 is fixed on the upright panel 30 tightly attached to the front side of the protection panel 99 using bolts or other fixing means, and the flood detection sensor 98 is provided to be spaced apart from the bottom side of the upper plate 29 of the lower support 20. At this point, the flood detection sensor 98 is installed to detect flooding in the accommodation space of the lower support 20 formed in a “Π” shape, and a contact sensor or a non-contact sensor is installed and used according to design requirements, so that a double safety structure is implemented against flooding by transferring a flood detection signal to the solenoid valve 96 through the electric wire 97 when flooding in the accommodation space of the lower support 20 is detected by the flood detection sensor 98, discharging the air in the air compression tank 91 by opening the injection nozzle 96a of the solenoid valve 96, and pushing the water flowing into the inner box 60 including the lower support 20 to the outside using the internal pressure of the discharged air.
In addition, when the flood detection sensor 98 detects flooding, the flood detection signal is transferred to a computer or a portable terminal of the manager through wireless communication.
Unexplained reference numeral 41 is an electric wire entry and exit hole through which the electric wire passes.
