Abstract
Description
Technical Field
[0001] This invention relates to the field of tunnel water volume and pressure measurement technology, specifically to an intelligent measurement and alarm mechanism for tunnel water volume and pressure. Background Technology
[0002] As a permanent support structure maintaining the stability of the tunnel chamber, the water pressure behind the tunnel lining and the surface leakage rate are key coupled parameters for assessing structural safety and water hazard risk. The water pressure behind the tunnel lining directly reflects the fluid load acting on the lining, while the surface leakage rate is a direct representation of the lining's waterproofing failure and defect development. Simultaneous monitoring of both is of great significance for early warning of major risks such as lining cracking and increased leakage. The water pressure behind the lining is measured by a water pressure measuring probe penetrating through the lining to the gap between the lining and the rock strata, while the water pressure on the lining surface is measured by a flow meter aimed at the outlet.
[0003] Tunnel linings have several structural weaknesses, particularly the transverse construction joints between the arch and sidewalls. The waterproofing system at these joints is easily disturbed, making them high-risk areas for leakage and key monitoring points during operation. In practice, after cost accounting and professional evaluation, it is necessary to install integrated water flow and pressure measurement and alarm devices along these critical joints. When leakage occurs at a monitoring point, the flow meter measures the outflow in real time. Once the cumulative leakage reaches a preset safety threshold, the system will automatically trigger an alarm, providing maintenance personnel with repair guidance.
[0004] However, current monitoring solutions using intermittent deployment have inherent blind spots. Each measuring and alarm device can only respond sensitively to leaks at its installation location. If a leak occurs in the area between adjacent devices, it requires the water to spread along the lining surface to a nearby sensor before it can be detected. This process results in a significant lag in the system's perception of leaks in intermittent areas, and the measured flow rate and location data are no longer from the initial leak state. This leads to distorted monitoring results and delayed warnings, making it difficult to accurately reflect the origin and development of local leaks, thus weakening the timeliness and accuracy of the monitoring system.
[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing intelligent measurement and alarm mechanism for tunnel water volume and pressure. Summary of the Invention
[0006] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide an intelligent measurement and alarm mechanism for tunnel water volume and pressure, thereby solving the problem of inherent monitoring blind spots in the intermittent deployment monitoring schemes mentioned in the background.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a tunnel water volume and pressure intelligent measurement and alarm mechanism, comprising a protective box and a viewing mirror plate embedded in the front of the protective box, and further comprising: The water collection pipe is fixedly inserted at the top of the protective box in proportion; the suspension component is set inside the protective box to selectively shift the weight of the leaking water; and the measurement alarm component is set inside the protective box and dynamically adjusts the target point along the guide trajectory of the suspension component driven by its own weight. The suspension assembly includes tension rods symmetrically hinged to both sides of the bottom inside the protective box, a flexible rope movably fastened between the tops of the two sets of tension rods, several sets of water collection buckets movably arranged in proportion inside the protective box, and a spring fixed inside the bottom of the protective box. The measurement alarm component includes a measuring trolley that is movably installed inside a protective box and counterweights that are symmetrically fixed at both ends of the measuring trolley.
[0008] Preferably, the water collection pipe consists of a horn-shaped cover at the top and a straight pipe that is connected and fixed at the bottom of the horn-shaped cover; Several groups of the aforementioned water collection pipes are arranged horizontally at equal intervals; Several sets of speaker covers are connected end to end without gaps; The bottom of the straight tube extends into the interior of the protective box.
[0009] Preferably, each of the water collection buckets is located directly below each of the water collection pipes. The inner diameter of the water collection bucket is larger than the inner diameter of the straight pipe at the bottom of the water collection pipe; There is a clear gap between the top of the water collection bucket and the bottom of the water collection pipe.
[0010] Preferably, a torsion spring is provided at the hinge point between each tensioning rod and the bottom wall of the protective box; One end of the torsion spring is pressed against one side of the tension rod, and the other end of the torsion spring is pressed against the bottom wall of the protective box; The contact surfaces between the tensioning rod and the flexible rope are both polished and lubricated.
[0011] Preferably, the suspension assembly further includes several sets of limiting rails respectively fixed at the middle of the inner wall of the protective box and the outer wall of the water collection tank; The limiting rail is internally equipped with a cylindrical slider, and the contact surface between the cylindrical slider and the limiting rail is polished and lubricated. A set of connecting parts is fixed between each pair of cylindrical sliders.
[0012] Preferably, one end of the connector is movably fitted with a pull cord; The other end of the pull rope is movably secured with a loop; One end of the ring is fixedly connected to the surface of the flexible rope.
[0013] Preferably, a circular ring is fixedly fitted at the lower end of the water collection bucket; The top end of the spring is fixedly connected to the bottom surface of the circular sleeve; The bottom of the water collection tank is fixedly connected to a drain pipe via a solenoid valve. The bottom end of the drain pipe extends movably to the outside of the bottom end of the protective box.
[0014] Preferably, the measurement alarm component further includes a buzzer located on the other side of the measurement trolley; An alarm light is installed on the other side of the measuring trolley; A water pressure gauge is connected to the other side of the measuring trolley via a signal transmission line, and the water pressure gauge is located on the top outside of the protective box; The flow meter is located between the bottom of the water collection pipe and the top of the water collection tank.
[0015] Preferably, a limiting rod is hinged to the top of the measuring trolley; The inner wall of the protective box is rotatably equipped with a limiting sliding sleeve; The limiting rod is movably inserted into one end of the limiting sleeve; The contact surfaces of the limiting rod and the limiting sleeve are both polished and lubricated.
[0016] Preferably, a narrow plate is fixed in the middle of the bottom of the measuring trolley; A steel ball is rolled in the middle of the bottom of the narrow plate, and the steel ball rolls on the surface of the flexible rope. The surfaces of both the steel balls and the flexible rope have been polished and lubricated. There is a noticeable gap between the narrow plate and the flexible rope.
[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a densely arranged array of water collection pipes, connected end-to-end, to achieve continuous coverage of critical weak areas such as construction joints between the tunnel arch and sidewalls, significantly reducing monitoring blind spots. When leakage occurs at any location within the construction joint, the water is quickly captured by the corresponding water collection pipe and channeled into a collection bucket below. As the water accumulates in the collection bucket, its weight increases, causing it to shift downwards, resulting in a distinct "V"-shaped bend in the horizontally tensioned flexible rope at that point. Based on this mechanical structure, the measurement and alarm component can adaptively slide along the flexible rope to the lowest point of the bend, i.e., below the water collection pipe with the largest leakage, and continuously monitor the water output at that point. This invention improves the monitoring method from discrete deployment to linear coverage and, through an adaptive positioning mechanism, enables the system to dynamically adjust the monitoring target point according to the leakage intensity. This not only significantly enhances the sensitivity and timeliness of sensing leakage events in intermittent areas but also ensures the authenticity and representativeness of the data. When the cumulative leakage at the monitoring point exceeds the preset threshold, the alarm system integrated into the measurement alarm component is immediately triggered, providing maintenance personnel with a more accurate and intuitive location of the hazard, thereby effectively supporting the precise maintenance and emergency response of tunnel structural safety.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Please see Figures 1 to 10 The present invention provides a technical solution: an intelligent measurement and alarm mechanism for tunnel water volume and pressure, comprising a protective box 1 and a viewing mirror plate 2 embedded in the front of the protective box 1, characterized in that it further comprises: The water collection pipe 3 is fixedly inserted at the top of the protective box 1 in proportion; the suspension assembly is set inside the protective box 1 to selectively shift the weight of the leaking water; and the measurement alarm assembly 18 is set inside the protective box 1 and dynamically adjusts the target point along the guide trajectory of the suspension assembly driven by its own weight. In practice, the surface of the protective box 1 must be equipped with an inspection port and a dehumidification channel to prevent moisture buildup inside the protective box 1 from affecting equipment operation. It is particularly important that the viewing mirror 2 be aligned with the measuring alarm component 18 to ensure that the measuring alarm component 18 can be observed through the viewing mirror 2 regardless of its position. Especially when the alarm light 183 illuminates, personnel can clearly locate the specific position of the measuring alarm component 18 and thus pinpoint the specific leak point.
[0031] The suspension assembly includes tension rods 5 symmetrically hinged to the bottom sides of the protective box 1, flexible ropes 6 movably fastened between the tops of the two sets of tension rods 5, several sets of water collection buckets 7 movably arranged in proportion inside the protective box 1, and springs 9 fixed inside the bottom of the protective box 1. In specific implementation, the flexible rope 6 can be made of steel wire rope with a polished surface or other materials that meet the requirements. The flexible rope 6 has a certain degree of flexibility but no elasticity, and has good wear resistance and corrosion resistance. Its surface needs to be smooth and flat to reduce the friction between it and 22. The specific material can be selected according to the requirements.
[0032] The measurement alarm component 18 includes a measuring trolley 181 movably disposed within the protective box 1 and counterweights 184 symmetrically fixed at both ends of the measuring trolley 181.
[0033] In specific implementation, as shown in the appendix Figure 8 As shown, in order to reduce obstruction of water flow from the water collection pipe 3 into the water collection tank 7 and to reduce damage to the internal components of the measuring carriage 181, the measuring carriage 181 is positioned on the side of the water collection tank 7, rather than directly above it. Since the flow meter 186 needs to be located in the middle of the water column, the extension plate 185 extends the flow meter 186 independently from the measuring carriage 181 and positions it between the water collection tank 7 and the water collection pipe 3. This disrupts the balance of the measuring carriage 181 itself. Although the limiting rod 19 and the limiting sleeve 20 restrict the measuring alarm component 18 from tipping over, the inherent imbalance will also bring greater continuous friction to the limiting rod 19 and the limiting sleeve 20, thus causing unnecessary resistance to the sliding of the measuring alarm component 18. Therefore, the design of the balancing counterweight 184 can adjust the balance of the measuring alarm component 18, so that the measuring alarm component 18 will not easily tip over even without the limiting rod 19 and the limiting sleeve 20, reducing the frictional resistance of the device movement. In addition, after the measuring alarm component 18 moves to the bend point of the flexible rope 6, it will swing back and forth due to inertia. Under the action of the counterweight 184, the measuring alarm component 18 can return to a stable state more quickly, significantly reducing the time of back-and-forth swinging, allowing the flow meter 186 to detect accurate data more quickly. Note: The specific shape of the counterweight 184 and the weight ratio at both ends need to be determined according to the actual design. Figure 8 The diagram is only a simple illustration, but the counterweight 184 is only used for balancing and should not have any excess weight.
[0034] The water collection pipe 3 consists of a horn-shaped cover at the top and a straight pipe that is connected and fixed at the bottom of the horn-shaped cover; Several groups of water collection pipes are arranged horizontally at equal intervals; Several sets of speaker covers are connected end to end without gaps; The bottom of the straight tube extends into the interior of the protective box 1.
[0035] In practice, the horn cover can be made into an elliptical, flat shape or other shapes, which can be customized according to the needs of the tunnel site. If necessary, it can be fixed to the tunnel wall using clamping plates and bolts. It should be noted that a flexible hose can be connected between the horn cover and the straight pipe, depending on the requirements. The purpose of the flexible hose is to facilitate changing the opening direction of the horn cover, allowing the horn cover to fit better with the perimeter of the construction joint. If there is no need to change the opening direction of the horn cover, a rigid straight pipe with lower water resistance can be used for connection.
[0036] Each set of water collection buckets 7 is located directly below each set of water collection pipes 3; The inner diameter of the water collection bucket 7 is larger than the inner diameter of the straight pipe at the bottom of the water collection pipe 3; In practice, the water flowing into the water collection pipe 3 is not likely to leak outside the water collection tank 7 when it enters the water collection tank 7, ensuring that the water can enter the water collection tank 7 to prevent water from accumulating inside the protective box 1. More importantly, it prevents the water collection volume from being distorted.
[0037] There is a clear gap between the top of the water collection bucket 7 and the bottom of the water collection pipe 3.
[0038] In practice, the interval is there to provide enough space for the flow meter 186 to move and prevent the flow meter 186 from colliding with the water collection pipe 3 or the water collection tank 7.
[0039] Each tensioning rod 5 is fitted with a torsion spring 17 at the hinge point between it and the bottom wall of the protective box 1. One end of the torsion spring 17 is pressed against one side of the tension rod 5, and the other end of the torsion spring 17 is pressed against the bottom wall of the protective box 1; In practical implementation, when the torsion spring 17 is not compressed by external force, it can make the two sets of tensioning rods 5 tighten the flexible rope 6, that is, the flexible rope 6 will not bend easily when it is not affected by the downward force of the water collection bucket 7.
[0040] The contact surfaces of tension rod 5 and flexible rope 6 are both polished and lubricated.
[0041] In specific implementation, as shown in the appendix Figure 7 As shown, the two ends of the flexible rope 6 are fastened to the top of the two sets of tensioning rods 5 in the form of loops. In this way, when the flexible rope 6 is pulled down in the middle, the two ends of the flexible rope 6 can rotate freely. Note: The top of the tensioning rod 5 needs to limit the two ends of the flexible rope 6 so that the flexible rope 6 can only be tensioned and pulled on one horizontal plane to prevent the flexible rope 6 from being misaligned with the steel ball 22.
[0042] The suspension assembly also includes several sets of limiting rails 12, which are respectively fixed in the middle of the inner wall of the protective box 1 and the outer wall of the water collection tank 7; A cylindrical slider 16 is slidably disposed inside the limiting rail 12, and the contact surface between the cylindrical slider 16 and the limiting rail 12 is polished and lubricated. A connecting piece 13 is fixed between every two sets of cylindrical sliders 16.
[0043] In specific implementation, as shown in the appendix Figure 6As shown, the cylindrical slider 16 can not only slide along the inside of the limiting rail 12, but also rotate independently of the limiting rail 12. This allows the connector 13 to slide vertically while also deflecting. This is because when one set of water collection buckets 7 pulls down the flexible rope 6, the positions of the other water collection buckets 7 remain unchanged. When the flexible rope 6 forms a "V" shape, its two ends are inclined. That is, although the other water collection buckets 7 will not move down, the other connectors 13 at the corresponding positions will be pulled diagonally downward by the flexible rope 6. The deflectable connector 13 can adapt to the positional relationship between the flexible rope 6 and the water collection buckets 7, so that when the downward angle of the flexible rope 6 is large, it can compensate for the rotation angle of the buckle 14 and the pull rope 15 to prevent the device from jamming.
[0044] One end of the connector 13 has a movable buckle with a pull cord 15; The other end of the pull rope 15 has a movable buckle 14; One end of the ring 14 is fixedly connected to the surface of the flexible rope 6.
[0045] In specific implementation, as shown in the appendix Figure 4 and attached Figure 5 As shown, only one end of the multiple sets of connectors 13 arranged in a horizontal array below the flexible rope 6 needs to be equipped with a pull rope 15. The connectors 13 on the other side of the water collection tank 7 do not need to be equipped with pull ropes 15. The pull rope 15 and the connectors 13, as well as the pull rope 15 and the ring buckle 14, are all connected by a ring buckle to ensure that both ends of the pull rope 15 can rotate freely. The parts of the connectors 13 that come into contact with the pull rope 15 need to be chamfered and ground to prevent the pull rope 15 from being damaged by friction over a long period of time.
[0046] The lower end of the water collection bucket 7 is fixedly fitted with a circular ring sleeve 10; The top end of spring 9 is fixedly connected to the bottom surface of ring sleeve 10; The bottom of the water collection tank 7 is fixedly connected to the drain pipe 8 via a solenoid valve 11; The bottom end of the drain pipe 8 extends movably to the outside of the bottom end of the protective box 1.
[0047] In practice, the spring 9 maintains a distance from the solenoid valve 11 during compression and rebound, and the two must not come into contact. When the measuring alarm component 18 reaches above a set of water collection tanks 7 at the corresponding position, the solenoid valve 11 needs to open to release water, gradually draining the water from the water collection tanks 7 to prevent the water from continuously accumulating in the water collection tanks 7, which would prevent the other water collection tanks 7 from pulling down the flexible rope 6. Note: The water release process is uniform, not erratic. Therefore, under the reset of spring 9, the water collection bucket 7 rises back to its original position at a constant speed. This means that the flexible rope 6 will gradually be taut at a constant speed. The measuring alarm component 18 located on the flexible rope 6 will not easily shift to other positions. Even if the water in the water collection bucket 7 at the location of the measuring alarm component 18 is decreasing, the measuring alarm component 18 will remain in the middle of the water collection bucket 7 and the water pipe 3 until another water collection bucket 7 at another location accumulates a certain amount of water and begins to pull down the flexible rope 6. Of course, under the action of torsion spring 17 and spring 9, the water collection buckets 7 at other locations need to accumulate a certain amount of water before they can move down, which provides sufficient time for the measuring alarm component 18 to measure.
[0048] The measurement alarm assembly 18 also includes a buzzer 182 located on one side of the measurement carriage 181; An alarm light 183 is installed on one side of the measuring trolley 181; A water pressure gauge 4 is connected to one side of the measuring trolley 181 via a signal transmission line, and the water pressure gauge 4 is located on the outside of the top of the protective box 1. An extension plate 185 is fixed to the other side of the measuring trolley 181, and a flow meter 186 is installed at one end of the extension plate 185; The flow meter 186 is located between the bottom of the water collection pipe 3 and the top of the water collection tank 7.
[0049] In practical implementation, sufficient length must be reserved for the signal transmission line to prevent the measurement alarm component 18 from being pulled by the signal transmission line during movement. The water pressure gauge 4 and flow meter 186 can be of suitable models; for example, the flow meter 186 can be an ultrasonic flow meter or other suitable flow meter. It should be noted that the measuring carriage 181 must be equipped with necessary electronic components such as a signal receiver, processor, and sensor. The water pressure gauge 4 transmits the detected water pressure information on the back of the lining to the signal receiver inside the measuring carriage 181 via the signal transmission line. Similarly, the flow meter 186 also transmits the water volume detection information to the signal receiver, which converts the data into an electrical signal and transmits it to the processor. After analyzing the data, if the processor finds that the water volume and pressure exceed the preset value, it sends a start command to the alarm light 183 and the buzzer 182. The alarm light 183 illuminates and the buzzer 182 sounds, providing an integrated sound and light alarm. When the flow meter 186 reaches above one of the water collection tanks 7, the sensor in the measuring trolley 181 detects the proximity switch in the solenoid valve 11 at the lower end of one of the water collection tanks 7, and the processor sends an opening command to the solenoid valve 11 at the corresponding position, allowing the water in one of the water collection tanks 7 to be discharged through the drain pipe 8. The specific measurement and alarm system operation process, the required electronic components, and their electrical connections are consistent with existing technologies; this invention only provides a brief description. It should also be noted that multiple sets of water pressure gauges 4 are not required; only one set needs to be installed at key locations. Monitoring data on the water volume on the lining surface at multiple points can also reflect the water pressure on the back side.
[0050] A limit rod 19 is hinged at the top of the measuring trolley 181; The inner wall of the protective box 1 is provided with a limit sleeve 20 for rotation; The limiting rod 19 is movably inserted into one end of the limiting sleeve 20; The contact surfaces of the limiting rod 19 and the limiting sleeve 20 are both polished and lubricated.
[0051] In practice, as the measuring alarm component 18 moves laterally, its height also changes. When the measuring alarm component 18 moves diagonally downward, it pulls on the limiting rod 19 and forces the limiting rod 19 and the limiting sleeve 20 to deflect, thus adapting to the positional change of the measuring alarm component 18. At the same time, under the limiting action of the limiting rod 19 and the limiting sleeve 20, the measuring alarm component 18 cannot tip over, that is, the steel ball 22 is always located on the upper surface of the flexible rope 6 and will not fall down.
[0052] A narrow plate 21 is fixed in the middle of the bottom of the measuring trolley 181; A steel ball 22 is rolled in the middle of the bottom of the narrow plate 21, and the steel ball 22 rolls on the surface of the flexible rope 6. Both the steel ball 22 and the flexible rope 6 have been polished and lubricated. There is a noticeable gap between the narrow plate 21 and the flexible rope 6.
[0053] In practice, the steel ball 22 always slides on the surface of the flexible rope 6, and the rolling friction resistance between the two is small. However, under the weight of the measuring alarm component 18, the bending angle of the flexible rope 6 needs to reach a certain degree for the measuring alarm component 18 to slide. It is not possible to move the measuring alarm component 18 with just a little pulling, so as to prevent the measuring alarm component 18 from moving back and forth on the flexible rope 6 and swaying.
[0054] Working Principle: When using this intelligent water volume and pressure measurement and alarm mechanism for tunnels, first install the protective box 1 in a suitable location inside the tunnel, and align the water collection pipe 3 with the key monitoring location. When water seeps in at a certain point, the water flows into the collection tank 7 through one of the corresponding sets of water collection pipes 3. After accumulating a certain amount, the weight of the collection tank 7 is significantly increased, causing the collection tank 7 to move downwards and compress the spring 9. As the collection tank 7 moves downwards, the connecting piece 13 moves downwards through the limiting rail 12 fixed to it. The connecting piece 13, under the limiting action of the limiting rail 12 fixed to the protective box 1, moves vertically downwards with the collection tank 7. The connecting piece 13 pulls down the flexible rope 6 through the pull rope 15 and the ring buckle 14 until the flexible rope 6 is in the corresponding position. A distinct angle is formed at the point of contact, and simultaneously, the two ends of the flexible rope 6 pull the tension rod 5, causing the tension rod 5 to rotate hingedly and compress the torsion spring 17. The steel ball 22 and the measuring alarm component 18 break free from the self-weight restraint of the measuring alarm component 18 and begin to roll along the already distinctly inclined surface of the flexible rope 6 toward the angle point of the flexible rope 6. As the measuring alarm component 18 moves, it pulls the limiting rod 19, forcing the limiting rod 19 and the limiting sleeve 20 to deflect, so that one end of the limiting rod 19 can move with the measuring alarm component 18, and thus affect the measurement. The alarm component 18 is constantly pulled to prevent the steel ball 22 from slipping off the surface of the flexible rope 6. This continues until the alarm component 18 moves to the bend of the flexible rope 6, which corresponds to the area below one of the water collection pipes 3 where the leakage is most severe. At this point, one of the solenoid valves 11 opens to release water, causing the water in one of the water collection tanks 7 to drain evenly along the drain pipe 8. As the weight of one of the water collection tanks 7 gradually decreases, the water collection tank 7 and the tension rod 5 return to their original positions steadily and evenly under the rebound of the spring 9 and torsion spring 17, and the flexible rope 6 is also repositioned. The system is gradually tightened, while the measuring alarm component 18 remains below one of the water collection pipes 3 to detect the water flow from the outlet of the water collection pipe 3. The water pressure gauge 4 normally detects the water pressure on the back of the lining. After the detection data is transmitted back to the processor in the measuring trolley 181, if the processor finds that the water volume or water pressure exceeds the preset value after analysis, the processor sends an activation command to the buzzer 182 and the alarm light 183 to realize the sound and light alarm. The staff can quickly and accurately locate the specific water seepage location through the perspective panel 2.
