[0002] Water leakage in underground tunnels on urban roads, highways, and other highways is a very common problem in road maintenance. If not discovered and addressed promptly, it can seriously impact the efficiency and quality of tunnel operations and cause safety accidents. Most highway tunnels are covered with decorative panels on the tunnel structure. These panels obscure the visibility of water leaks, making it difficult for tunnel maintenance inspectors to visually detect leaks behind the panels. Removing the panels to detect leaks significantly impacts vehicle traffic within the tunnel, is inefficient, and results in high labor costs. Summary of the Invention

[0003] The purpose of the present invention is to provide a highway tunnel water leakage monitoring device, system and method to solve the problems of difficulty in detecting tunnel water leakage by removing decorative panels, low detection efficiency, high detection cost, and complex detection process of removing tunnel wall decorative panels.

When the limit height is reached, a water immersion signal is generated and fed back to the controller;

[0009] An electric valve is connected to the controller and communicated with the water outlet of the water storage barrel. The electric valve is in a normally closed state to seal the water outlet of the water storage barrel for water storage. When the water immersion sensor generates a water immersion signal, the controller controls the electric valve to be in an open state within a predetermined discharge time period so that the water outlet of the water storage barrel is opened to discharge the water in the water storage barrel. After the predetermined discharge time period ends, the controller controls the electric valve to return to the normally closed state.

[0010] Furthermore, in the highway tunnel water leakage monitoring device provided by the present invention, the water storage barrel is a round barrel or a square barrel.

[0016] Installing a number of highway tunnel water leakage monitoring devices at equal intervals on the wall of the highway tunnel, and connecting the water pipes of the highway tunnel water leakage monitoring devices to the diversion trough through the decorative panels on the wall of the highway tunnel;

[0017] When water leakage occurs in a highway tunnel, the leaked water flows into the diversion trough. The water pipe guides the water in the diversion trough into the water storage bucket. The water level in the water storage bucket is detected by the water sensor. When the water sensor generates a water immersion signal, the controller controls the electric valve to be in an open state within a predetermined discharge time period, so that the water outlet of the water storage bucket is opened to discharge the water in the water storage bucket. After the predetermined discharge time period ends, the controller controls the electric valve to return to a normally closed state.

[0018] When inspecting highway tunnels, tunnel maintenance inspectors check whether there is water accumulation or drainage marks on the ground corresponding to the electric valve of the water storage bucket of each highway tunnel water leakage monitoring device to determine whether the highway tunnel is leaking without removing the decorative panels, or check whether there is water rust on the electric valve to determine whether the highway tunnel is leaking without removing the decorative panels.

[0019] Compared with the prior art, the road tunnel water leakage monitoring device and method provided by the present invention have the following beneficial effects:

[0020] When inspecting highway tunnels, tunnel maintenance inspectors can determine whether there is water accumulation or drainage marks on the ground corresponding to the electric valve of the water storage bucket of each highway tunnel leakage monitoring device, or whether there is water rust on the electric valve, so as to determine whether there is leakage in the highway tunnel without removing the decorative panels. This method has the advantages of simple and convenient detection process, high detection efficiency and low detection cost, and solves the problems of traditional detection methods such as the need to remove decorative panels, complex detection process, the need to resume construction, resulting in detection difficulties, low detection efficiency and high detection costs.

The water pipes connected to the highway tunnel water leakage monitoring devices in the same diversion trough lead the water in the diversion trough into the water storage buckets. Each water level sensor detects the water level in the corresponding water storage bucket. When each water level sensor generates a water level signal, each controller controls the connected electric valve to be open for a predetermined discharge time period, thereby opening the water outlet of the water storage bucket and discharging the water in the corresponding water storage bucket. After the predetermined discharge time period ends, each controller controls the connected electric valve to return to the normally closed state.

[0028] Each highway tunnel water leakage monitoring device records its device number information through its controller and uploads its device number information and water immersion signal time data to the cloud server through the wireless network module.

[0041] The present invention will be described in detail below with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and are not accurately scaled, and are only used to facilitate and clearly illustrate the embodiments of the present invention.

[0042] Example 1

[0043] Please refer to Figures 1 to 3 The first embodiment of the present invention provides a road tunnel water leakage monitoring device 110, including a water storage bucket 111, a water receiving pipe 112, a controller 113, a water immersion sensor 114 and an electric valve 115, wherein:

[0044] Water storage barrel 111 is arranged vertically and has a water inlet at its top and a water outlet at its bottom for storing water. To achieve this, the shape of water storage barrel 111 includes, but is not limited to, a round barrel, a square barrel, a conical barrel, or a combination thereof. The figure illustrates a water storage barrel 111 in the form of a combination of a round barrel and a conical barrel, with the conical barrel having a water outlet at its lower end. The lower portion of water storage barrel 111 can be the lower side or bottom of water storage barrel 111.

[0045] A water receiving pipe 112 is connected to the upper portion of the water storage barrel 111 through a water inlet and is used to receive leaking water from the highway tunnel 200. The water receiving pipe 112 includes but is not limited to one pipe. The connection position between the water receiving pipe 112 and the water storage barrel 111 is not limited to horizontal connection. The connection position and shape of the water receiving pipe 112 can be adjusted according to the conditions of the wall 210 of the highway tunnel 200. For example, the water receiving pipe 112 can be connected to the water storage barrel 111 at an angle relative to the horizontal plane.

[0046] The controller 113 includes but is not limited to a microprocessor such as a single chip microcomputer and a CPLD.

[0047] A water sensor 114, connected to the controller 113, is disposed within the water storage barrel 111. The sensing surface of the water sensor 114 is located at a limit height below the water inlet and staggered relative to the water inlet. The sensor is configured to detect whether the water level within the water storage barrel 111 has reached the limit height. Upon reaching the limit height, the sensor generates a water immersion signal and feeds it back to the controller 113. The staggered positioning of the sensing surface of the water sensor 114 relative to the water inlet prevents false detections caused by water flowing directly through the sensor 114 at the communication port. The limit height refers to the point at which the water within the water storage barrel 111 reaches the sensing surface of the water sensor 114. This limit height corresponds to the height of the sensing surface, also known as the installation height of the water sensor. When the water level within the water storage barrel 111 reaches the installation height of the water sensor 114, the sensor 114 is triggered to generate a water immersion signal. Figure 1 The dotted line position in the figure illustrates the water level line situation in the water storage barrel 111. In order to facilitate the installation of the water immersion sensor 114, a limit line with a limited height can be set on the inner wall of the water storage barrel 111.

[0048] Electric valve 115 is connected to controller 113 and communicates with the water outlet of water storage barrel 111. Electric valve 115 is normally closed, sealing the outlet of water storage barrel 111 for water storage. When water sensor 114 generates a water ingress signal, controller 113 controls electric valve 115 to open for a predetermined draining period, allowing the outlet of water storage barrel 111 to open and drain water from the barrel. After the predetermined draining period, controller 113 controls electric valve 115 to return to the normally closed state. In other words, when electric valve 115 is closed, water storage barrel 111 stores water, and when electric valve 115 is open, water is drained from the barrel. Electric valve 115 may be a solenoid valve, an electric ball valve, or the like. Electric valve 115 is controlled to open or close based on the signal received by controller 113 from water sensor 114. When electric valve 115 returns to the normally closed state, water storage barrel 111 begins the next round of water storage.

[0049] To improve the stability and safety of the controller 113, the highway tunnel water leakage monitoring device 110 provided in the first embodiment of the present invention can be configured such that the controller 113 is mounted on the outer wall of the water storage tank 111 via a housing. To prevent water droplets on the outer wall of the water storage tank 111 from affecting the stability of the controller 113, the controller 113 can be fixed to the wall 210 or decorative panel 230 of the highway tunnel via the housing. The controller 113 can be powered by a rechargeable battery, which can be charged via electrical wiring within the highway tunnel.

[0050] To prevent drainage from accumulating on the tunnel floor 250, potentially impacting vehicle traffic and potentially causing traffic accidents, the first embodiment of the present invention provides a tunnel water leakage monitoring device 110. The outlet of the water storage tank 111 is connected to a water outlet pipe (not shown), and the electric valve 115 is connected to the water outlet pipe. This outlet pipe can change the direction and location of drainage, preventing drainage from accumulating on the tunnel floor 250.

[0051] Please refer to Figures 1 to 3 The first embodiment of the present invention further provides a road tunnel water leakage monitoring method based on the road tunnel water leakage monitoring device 110, which may include:

[0052] In step 301, a plurality of the aforementioned road tunnel water leakage monitoring devices 110 are installed at equal intervals on the wall 210 of the road tunnel 200. The water inlet pipe 112 of each road tunnel water leakage monitoring device 110 is passed through the decorative panel 230 on the wall 210 of the road tunnel 200 and connected to the diversion trough 240. The diversion trough 240 is installed on the tunnel structure layer via a bracket 220.

[0053] In step 302, when water leakage occurs in highway tunnel 200, the leaked water flows into diversion trough 240. Water inlet pipe 112 directs the water in diversion trough 240 into water storage tank 111. Water sensor 114 detects the water level in water storage tank 111. When water sensor 114 generates a water level signal, controller 113 controls electric valve 115 to open for a predetermined discharge time period, thereby opening the outlet of water storage tank 111 and discharging the water in water storage tank 111. After the predetermined discharge time period, controller 113 controls electric valve 115 to return to a normally closed state. When the water level in water storage tank 111 reaches a limit height, water sensor 114 generates a water level signal; otherwise, no water level signal is generated.

[0054] In step 303, when inspecting the highway tunnel 200, the tunnel maintenance inspection personnel detect whether there is water accumulation or drainage marks on the ground 250 corresponding to the electric valve 115 of the water storage barrel 111 of each highway tunnel water leakage monitoring device 110, so as to determine whether the highway tunnel 200 has leaked without removing the decorative panel 230, or detect whether there is water rust on the electric valve 115, so as to determine whether the highway tunnel 200 has leaked without removing the decorative panel 230.

[0055] The highway tunnel water leakage monitoring device 110 and method provided in the first embodiment of the present invention have the advantages of simple and convenient detection process, high detection efficiency and low detection cost, which solves the problem that the traditional detection method requires the removal of decorative panels, the detection process is complicated, and the construction needs to be resumed, resulting in detection difficulties, low detection efficiency and high detection costs.

[0056] Example 2

[0057] Please refer to Figures 1 to 4 In order to avoid manual inspections, the second embodiment of the present invention provides a highway tunnel water leakage monitoring system, including a front-end display device 130, a cloud server 120 and a number of the above-mentioned highway tunnel water leakage monitoring devices 110, each of the highway tunnel water leakage monitoring devices 110 also includes a wireless network module 120 connected to the controller 113, each of the highway tunnel water leakage monitoring devices 110 is connected to the cloud server 120 through the wireless network module 120, and the front-end display device 130 is connected to the cloud server 120. The front-end display device 130 includes but is not limited to smart phones, tablet computers, laptops, desktop computers and other display terminals. The wireless network module 120 includes but is not limited to 2G / 3G / 4G / 5G communication modules, NB-IoT (narrowband Internet of Things), WIFI network modules, etc. The WIFI network module needs to be configured with network devices such as routers and switches to access the Internet.

[0058] Here's how it works:

[0059] Each highway tunnel water leakage monitoring device 110 records its device number information through its controller 113 and uploads its device number information and water immersion signal time data to the cloud server 120 through the wireless network module 120. The cloud server 120 calculates the drainage volume per unit time based on the water immersion signal time data of each numbered highway tunnel water leakage monitoring device 110. The front-end display device 130 obtains the drainage volume data per unit time of each highway tunnel water leakage monitoring device 110 and displays it visually according to the water immersion signal time, thereby performing remote intelligent monitoring of the water leakage situation in the highway tunnel.

[0060] In order to calculate the drainage volume of each highway tunnel water leakage monitoring device 110 per unit time, the highway tunnel water leakage monitoring system provided in the second embodiment of the present invention, the cloud server 120 calculates the drainage volume of the highway tunnel water leakage monitoring device 110 per unit time according to formula (1).

[0061]

[0062] Wherein, q is the drainage volume per unit time of the highway tunnel water leakage monitoring device 110, Q is the water storage volume of the water storage tank 111 when the water level is at the limit height, t 后 is the time of the last flooding signal, t 前 is the time of the previous flooding signal, t 排The discharge volume q of each road tunnel water leakage monitoring device 110 represents the water leakage situation near its installation location, thereby obtaining the complete water leakage situation of the road tunnel 200 and realizing the monitoring of the water leakage volume of the road tunnel 200.

[0063] Please refer to Figures 1 to 4 The second embodiment of the present invention further provides a road tunnel water leakage monitoring method based on the road tunnel water leakage monitoring system, comprising:

[0064] In step 401 , a plurality of highway tunnel water leakage monitoring devices 110 are installed at equal intervals on the wall 210 of the highway tunnel 200 , and the water receiving pipe 112 of each highway tunnel water leakage monitoring device 110 is passed through the decorative panel 230 on the wall 210 of the highway tunnel 200 and connected to the diversion groove 240 .

[0065] Step 402, when water leakage occurs somewhere in the highway tunnel, the leaked water flows into the diversion trough 240, and the water receiving pipes 112 connected to the highway tunnel water leakage monitoring devices 110 in the same diversion trough 240 lead the water in the diversion trough 240 into the water storage barrels 111. The water immersion sensors 114 detect the water level in the corresponding water storage barrels 111. When the water immersion sensors 114 generate a water immersion signal, the controllers 113 control the connected electric valves 115 to be in an open state within a predetermined discharge time period, so that the water outlet of the water storage barrel 111 is opened to discharge the water in the corresponding water storage barrel 111. After the predetermined discharge time period ends, the controllers 113 control the connected electric valves 115 to return to a normally closed state.

[0066] In step 403, each highway tunnel water leakage monitoring device 110 records its device number information through its controller 113 and uploads its device number information and water immersion signal time data to the cloud server 120 through the wireless network module 120. The cloud server 120 calculates the drainage volume per unit time based on the water immersion signal time data of each numbered highway tunnel water leakage monitoring device 110. The front-end display device 130 obtains the drainage volume data per unit time of each highway tunnel water leakage monitoring device 110 and displays it visually according to the water immersion signal time, thereby performing remote intelligent monitoring of the water leakage situation in the highway tunnel.

[0067] The highway tunnel water leakage monitoring system and method provided in the second embodiment of the present invention uses a cloud server 120 to calculate the water discharge per unit time based on the flooding signal time data of each numbered highway tunnel water leakage monitoring device 110. This allows remote monitoring of whether a highway tunnel has water leakage, as well as remote monitoring of the water leakage volume at the leakage point. This automated and intelligent highway tunnel water leakage monitoring eliminates the need for on-site inspections by tunnel maintenance personnel, eliminates the need to remove decorative wall panels for inspection, does not occupy highway tunnel sections, and does not affect vehicle traffic within the tunnel. The system provides tunnel maintenance personnel with real-time highway tunnel water leakage data, assisting them in making decisions on whether to perform maintenance on the highway tunnel. The system offers the advantages of simple detection, high monitoring efficiency, good timeliness, and low labor costs.

They are not only suitable for highway tunnels, but also for detecting and monitoring water leakage in walls with decorative panels added to sunken underground squares, and have the advantage of a wide range of applications.
