Conventionally, in general, wiring such as power lines or communication lines for power transmission and various piping such as water supply, sewage, or gas pipes are installed in such a way as to be buried underground, thus facilitating management and maintenance of underground facilities buried underground. To do this, a manhole is installed at the end or middle of the underground facility.

Such a manhole is usually covered with a manhole cover to block it from the ground, but depending on the characteristics of the underground space and the deterioration of the facility, if rainwater or groundwater flows into the inside or flooding occurs due to damage or leakage of nearby water supply and sewage pipes there is

In addition, if flooding occurs inside the manhole, especially when power lines or communication lines are buried, large-scale accidents such as large-scale power outages or communication disruptions may occur due to flooding. It can be said that it is important to respond immediately, such as identifying and performing maintenance.

Here, as described above, an example of the prior art related to an apparatus and method for detecting whether inundation or water leakage occurs inside a manhole is first, for example, as presented in Korean Patent Laid-Open No. 10-2020-0027743 There is a "floating complex sensor module device and a water level measurement system inside a manhole using the same".

More specifically, the above Korean Patent Publication No. 10-2020-0027743 discloses a floating case that can float on the surface of the water when flooded inside a manhole; And a complex sensor module embedded in the floating case and detecting the state inside the manhole, including a complex sensor module embedded in the floating case, forming a hole at the top of the floating case and attaching a porous film tape to temperature and humidity By being configured to be able to measure, it relates to a floating complex sensor module device configured to float on the water surface even in a submerged environment inside a manhole to measure and detect the water level inside a manhole and a water level measurement system inside a manhole using the same.

In addition, as described above, another example of the prior art related to a device and method for detecting whether flooding or water leakage occurs inside a manhole is, for example, "manhole flooding" as presented in Korean Patent Registration No. 10-1880571. anti-theft device and method".

More specifically, the above Korean Patent Registration No. 10-1880571 discloses a smart sensor that measures the manhole level and detects the presence or absence of a manhole to generate a flooding accident or theft event; A GIS communication flood/theft management server that collects and manages the water level measured by the smart sensor and the presence or absence of manholes to generate the location of a flooding accident and a theft event with a field worker's smart phone; And including on-site smart phones that receive manhole flooding accident locations or theft events and dispatch to the accident site, accurately measure the water level with ultrasonic waves or bladders, and in the event of manhole theft or flooding, the site manager mobilizes according to the location information on the GIS to take action It relates to a manhole flooding anti-theft device and method configured to do so.

In addition, as described above, another example of the prior art related to a device and method for detecting whether or not water leakage or water leakage occurs inside a manhole is, for example, as presented in Korean Patent Publication No. 10-2018-0042665 There is "a manhole flood confirmation system and a flood confirmation device constituting the manhole".

More specifically, the above Korean Patent Publication No. 10-2018-0042665 discloses a submersion confirmation device including a floating body floating in a manhole; And including a pipe detector that detects the floating body of the flood confirmation device and checks whether the manhole is flooded, the flood confirmation device that can be operated at all times without excessive cost can be installed on all manholes to check whether the manhole is flooded. It relates to a manhole flood confirmation system configured to be easily confirmed and a flood confirmation device constituting the same.

As described above, various technical contents related to devices and methods for detecting submersion or water leakage inside a manhole have been proposed, but the contents of the prior art as described above have the following problems.

That is, as described above, in general, not only water and sewage pipes but also various facilities such as power lines and communication lines are buried inside the manhole, and rainwater or groundwater flows in or nearby water and sewage pipes due to the nature of the inside of the manhole being buried underground. Water leakage or flooding may occur due to leakage or damage of the

Moreover, if water leakage or flooding occurs inside a manhole, especially in the case of a manhole with power lines or communication lines buried, accidents such as large-scale power outages or communication disruptions may occur due to flooding. However, enormous damage will occur beyond the level of temporary communication failure.

However, manholes in the prior art are generally not equipped with a separate configuration or function for detecting whether or not there is inundation and leakage inside the manhole, such as a submersion and leakage detection device, so that inundation or leakage inside the manhole Even if it occurs, it cannot be immediately detected and dealt with, and as a result, there is a limit to effectively preventing the risk of small defects leading to large-scale accidents.

In addition, the manhole of the prior art, due to the nature of being buried underground, had a problem in that it was difficult to additionally install a separate device or system for detecting inundation and leakage after construction.

In addition, recently, a submersion detection system configured to receive and manage the condition inside the manhole by receiving various sensor signals installed inside the manhole through a wireless communication terminal has been proposed, but these conventional submersion detection systems have the overall configuration In addition to this complexity, there is a problem that the operation of the sensor becomes impossible when the internal structure is flooded due to the structure of the underground manhole.

Moreover, when a waterproof sensor is used to solve this problem, it is very expensive compared to conventional sensors, so the cost increases significantly, and in addition, due to the disadvantage of making it difficult to miniaturize the entire system, it is difficult to secure the space inside the manhole due to the nature of the underground space. There is a problem that is not appropriate to install on .

Therefore, in order to solve the problems of the prior art manhole as described above, for example, a manhole cover having a detection function capable of detecting submersion and leakage at a relatively simple configuration and low cost is implemented, and the manhole cover is replaced. By replacing and installing a manhole cover with a flood and water leak detection function at the time of installation or new installation, it is immediately detected when flood or water leak occurs inside the manhole and sends a notification to the manager or control center to perform maintenance It is desirable to present a manhole structure of a new configuration configured to effectively prevent the occurrence of large-scale accidents and minimize damage, but a device or method that satisfies all such demands has not yet been presented.

Subsequently, with reference to the drawings, the detailed contents of the submersion and water leakage detection device according to the present invention and the manhole cover having a submersion and water leakage detection function using the same will be described.

In more detail, first, referring to FIG. 1, FIG. 1 is a diagram schematically showing the overall configuration of a submersion and water leakage detection device 10 according to an embodiment of the present invention.

As shown in FIG. 1, the submersion and water leakage detection device 10 according to an embodiment of the present invention is largely divided into a terminal unit 11 including a detection terminal for detecting the occurrence of submersion or water leakage, a NAND gate and Using the same logic gate, a logic circuit unit 12 outputs a signal indicating whether flooding or water leakage occurs according to a signal received from the terminal unit 11, and flooding and water leakage based on an input signal transmitted from the logic circuit unit 12 A microcontroller (including a Micro Controller Unit (MCU)) configured to determine whether or not water leakage occurs and notify a predetermined contact person such as a person in charge or a control center in case of flooding or water leakage to perform maintenance. It may be configured to include a control unit 13 and a communication unit 14 for performing communication in at least one communication method among wired or wireless communication methods such as an external device or control server and exchanging various data.

Here, the submersion and water leakage detection device 10 according to the embodiment of the present invention described above, although not shown, for example, a power supply unit including a power supply means for supplying power, such as an external power source or a battery It may be configured to further include.

In addition, the above-described terminal unit 11 is formed by removing the coating of one end of the coated wire by a certain length to expose the + terminal and the - terminal to the outside, such as, for example, a lead wire. It can be configured to hang downward inside the manhole.

That is, referring to FIG. 2, FIG. 2 is a diagram schematically showing a specific configuration of the terminal unit 11 of the submersion and water leakage detection device 10 according to the embodiment of the present invention.

As shown in Fig. 2, the above-described terminal portion 11 is formed by removing the coating on one end side of a wire including an outer sheath 21 and an inner sheath 22 by a predetermined length, for example, like a lead wire. By allowing the inner core 23 to be exposed in, it can be configured to form a + terminal and a - terminal, respectively, through each of the exposed inner cores 23.

At this time, in order to prevent malfunction, as shown in FIG. 2, each terminal may be configured to be formed with a predetermined interval between the + terminal and the - terminal so that they do not contact each other.

In addition, as shown in FIG. 1, the logic circuit unit 12 normally outputs a Low (0) signal using, for example, a NAND gate, and the + terminal and the - terminal of the terminal unit 11 are electrically connected. It can be configured to minimize power consumption by outputting a High (1) signal only when connected to .

In more detail, referring to FIG. 3 , FIG. 3 is a diagram schematically showing a specific configuration of the logic circuit unit 12 of the submersion and water leakage detection device 10 according to an embodiment of the present invention.

As shown in FIG. 3, in the logic circuit unit 12, the + terminal (or - terminal) of the terminal unit 11 is connected to the power source VCC, and the first input terminal of the NAND gate is connected to the terminal unit 11. The - terminal (or + terminal) is connected, and the second input terminal of the NAND gate may be configured to be connected to ground (GND).

Therefore, from the configuration as described above, a Low (0) signal is normally output, but when the + terminal and - terminal of the terminal unit 11 are electrically connected to each other due to water leakage or flooding, the output of the NAND gate becomes High (1) The input signal input to the MCU of the controller 13 is changed to High (1).

At this time, the above-described logic circuit unit 12 may be configured to periodically output a Low or High signal at regular intervals or at regular intervals according to predetermined settings in order to prevent malfunction.

Similarly, the MCU of the control unit 13 also transmits current status and monitoring data to an external device or control center through the communication unit 14 periodically at regular intervals or at regular times according to predetermined settings in order to prevent malfunctions. It may be configured so that the processing is performed.

In addition, the MCU of the control unit 13, for example, based on a predetermined set value, determines that flooding has occurred when the High signal is continuously input for a predetermined time, and the High signal is generated for a predetermined time. If it does not continue, it may be configured to determine that a leak has occurred, and these judgment conditions may be configured in various ways depending on circumstances and needs.

Therefore, from the configuration as described above, when water is filled inside the manhole to the location where the + terminal and - terminal exposed to the outside of the terminal unit 11 are installed due to leakage or flooding, each terminal is electrically connected to each other, A high signal is output from the NAND gate of the circuit unit 12 and input to the MCU of the control unit 13, and when the high signal is input, the MCU determines that submersion or water leakage has occurred, informs the fact through the communication unit 14, and maintains By being configured to perform the requesting process, it is possible to prevent large-scale accidents in advance and minimize damage by immediately identifying and coping with the occurrence of flooding or water leakage inside the manhole.

In addition, since the submersion and water leakage detection device 10 according to an embodiment of the present invention can be easily implemented using only a lead wire and a single logic gate and MCU as described above, it is relatively simple and inexpensive It also has the advantage of being able to detect submersion and leakage quickly and accurately.

Here, in the above embodiment of the present invention, the present invention has been described by taking the case where the above-described logic circuit unit 12 is configured using a NAND gate as an example, but the present invention is necessarily limited to the configuration presented in the above embodiment That is, the present invention, for example, the above-described logic circuit unit 12 may be configured using other logic gates in addition to the NAND gate, etc. It should be noted that it can be modified and changed in various ways by those skilled in the art as needed.

Continuing to refer to FIGS. 4 and 5 , FIGS. 4 and 5 are diagrams each schematically illustrating an example of an actual configuration of a submersion and water leakage detection device 10 according to an embodiment of the present invention.

In addition, as shown in FIG. 4, in the above terminal unit 11, a lead wire exposed to the outside from one side of the housing is stretched downward as long as a required length and the coating is removed from the end to form a + terminal and a - terminal, respectively. can be configured to

Alternatively, as shown in FIG. 5, the terminal unit 11 may be configured in various forms as needed, such as being configured in a form in which only + terminals and - terminals are exposed on the lower surface of the housing. should be mindful of

Therefore, as described above, the submersion and water leakage detection device 10 according to the embodiment of the present invention can be implemented, and using this, a manhole cover having a submersion and water leakage detection function can be easily implemented.
