Description

Technical Field

[0001] This utility model relates to the technical field of water leakage monitoring devices, and in particular to a tunnel water leakage monitoring device. Background Technology

[0002] Water leakage in tunnels is one of the common problems during the operation of tunnel projects. If it is not monitored and treated in time, it may lead to problems such as corrosion of the lining structure, rust of steel bars, slippery road surface (causing traffic accidents), and damage to electromechanical equipment, which seriously affect the structural safety and service life of the tunnel. Therefore, it is necessary to monitor water leakage in tunnels.

[0003] A patent document with authorization publication number CN219161581U discloses a tunnel leakage monitoring device. This device includes at least two tunnel sections, with a monitoring device installed on the inner wall of the joint between the two sections. The monitoring device includes a housing, with a liquid level sensor body for liquid level monitoring and a sealing plug for leakage discharge at both ends of the bottom of the housing. This patent document, by installing a monitoring device composed of a housing, a liquid level sensor body, and a data processor body on the inner wall of the tunnel joint, enables real-time monitoring of leakage at the tunnel joint, replacing the periodic monitoring used in the prior art. This ensures timely understanding of the leakage situation at the tunnel joint by personnel and reduces the workload of periodic monitoring.

[0004] The above-mentioned and existing technologies have the following drawbacks: In the process of detecting water leakage in tunnels, the leakage water is collected and monitored by means of components such as shells. However, when water leakage occurs, this monitoring method cannot determine the seepage point of the water leakage, making it difficult to seal the seepage point in a timely manner.

[0005] Therefore, a tunnel leakage monitoring device is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of traditional methods of collecting and monitoring seepage water using components such as casings, which cannot identify the seepage point when seepage occurs, making it difficult to seal the seepage point in a timely manner. Therefore, this invention proposes a tunnel seepage water monitoring device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tunnel water leakage monitoring device, comprising a tunnel and several sealing plates, an arched frame fixedly connected to the joint of the tunnel, several bolts slidingly passing through the sealing plate, the bolts being threadedly connected to the arched frame, several humidity sensors fixedly connected to the sealing plate, and a sponge pad fixedly connected to the surface of the sealing plate, the sponge pad being sleeved on the surface of the humidity sensors.

[0008] The effect achieved by the above components is as follows: by setting up a sealing plate, a sponge pad, and a humidity sensor, when water seeps into the tunnel joint, the water will first be absorbed by the sponge pad at the corresponding location, causing the humidity sensor in that area to detect abnormal humidity, thereby determining the distribution point of the seepage water and facilitating the rapid sealing of the seepage point.

[0009] Preferably, a plurality of the humidity sensors are arranged in a circumferential array within the sealing plate.

[0010] The effect achieved by the above components is that, since the humidity sensors are distributed in an array, by comparing the humidity data of sensors at different locations, the seepage point of water leakage can be located more accurately.

[0011] Preferably, a sealing gasket is fixedly connected to the surface of the sealing plate, and the sealing gasket is located between the arched frame and the sealing plate.

[0012] The effect achieved by the above components is that the sealing gasket between the sealing plate and the arched frame enhances the sealing of the connection, ensuring that leaking water can only affect the monitoring area.

[0013] Preferably, a guide frame is fixedly connected to the surface of the sealing plate, and a fixing block is fixedly connected to the surface of the arched frame, with the guide frame and the fixing block being slidably connected.

[0014] The effect achieved by the above components is that during installation, the fixing block on the arched frame slides and engages with the guide frame on the sealing plate, thus achieving a pre-positioning function.

[0015] Preferably, a pin slides through the fixed block, and the pin passes through the guide frame.

[0016] The effect achieved by the above components is that the pins can prevent the sealing plate from falling off due to the worker's slipping hand during installation.

[0017] Preferably, a spring is fitted onto the surface of the pin, and the two ends of the spring are fixedly connected to the pin and the fixing block, respectively.

[0018] The effect achieved by the above components is that the pin can quickly penetrate the guide frame and the fixing block under the action of the spring force.

[0019] Preferably, one end of the guide frame has an inclined surface.

[0020] The effect achieved by the above components is that the inclined surface at one end of the guide frame allows the pin to automatically avoid obstacles when the guide frame slides, thus improving the ease of installation.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a sealing plate, a sponge pad, and a humidity sensor, when water seepage occurs at the tunnel joint, the water will first be absorbed by the sponge pad at the corresponding location, causing the humidity sensor in that area to detect abnormal humidity, thereby determining the distribution point of the seepage water and facilitating quick sealing of the seepage point.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figures 1-5As shown, this utility model provides a tunnel water leakage monitoring device, including a tunnel 1 and several sealing plates 3. An arched frame 2 is fixedly connected to the joint of the tunnel 1. Several bolts 4 slide through the sealing plate 3 and are threadedly connected to the arched frame 2. Several humidity sensors 5 are fixedly connected inside the sealing plate 3. A sponge pad 6 is fixedly connected to the surface of the sealing plate 3 and is fitted onto the surface of the humidity sensor 5. By setting up the sealing plate 3, sponge pad 6 and humidity sensor 5, when water leakage occurs at the joint of the tunnel 1, the water will first be absorbed by the sponge pad 6 at the corresponding position, causing the humidity sensor 5 in that area to detect abnormal humidity, thereby determining the distribution point of the seepage water and facilitating quick sealing of the seepage point. Several humidity sensors 5 are arranged in a circumferential array inside the sealing plate 3. Since the humidity sensors 5 are arranged in an array, by comparing the humidity data of sensors at different positions, the seepage point of the water leakage can be further accurately located.

[0032] A sealing gasket is fixedly connected to the surface of the sealing plate 3. The sealing gasket is located between the arched frame 2 and the sealing plate 3. The sealing gasket between the sealing plate 3 and the arched frame 2 enhances the sealing of the connection and ensures that the leaking water can only act on the monitoring area.

[0033] A guide frame 8 is fixedly connected to the surface of the sealing plate 3, and a fixing block 9 is fixedly connected to the surface of the arched frame 2. The guide frame 8 and the fixing block 9 are slidably connected. During installation, the fixing block 9 on the arched frame 2 and the guide frame 8 on the sealing plate 3 slide together to play a pre-positioning role.

[0034] A pin 10 slides through the fixed block 9 and passes through the guide frame 8. The pin 10 can prevent the sealing plate 3 from falling off due to the worker's slip during installation.

[0035] A spring 11 is fitted on the surface of the pin 10. The two ends of the spring 11 are fixedly connected to the pin 10 and the fixing block 9, respectively. Under the elastic force of the spring 11, the pin 10 can quickly penetrate the guide frame 8 and the fixing block 9.

[0036] One end of the guide frame 8 has a bevel, which allows the pin 10 to automatically avoid the guide frame 8 when it slides, thus improving the ease of installation.

[0037] The overall working principle is as follows: by fixing the arched frame 2 at the joint of tunnel 1, the sealing plate 3 with multiple humidity sensors 5 is tightly connected to the arched frame 2 by bolts 4, forming a covering monitoring structure for the joint of tunnel 1. The sealing gasket between the sealing plate 3 and the arched frame 2 enhances the sealing of the connection, ensuring that the leakage water can only act on the monitoring area.

[0038] Several humidity sensors 5 are arranged in a circumferential array inside the sealing plate 3. The sponge pads 6 covering their surfaces can quickly absorb moisture that seeps into the joints. When water seeps into the joints of tunnel 1, the moisture will be absorbed by the sponge pads 6 at the corresponding positions first, causing the humidity sensors 5 in that area to detect abnormal humidity, thereby determining the distribution point of the seepage water. Since the humidity sensors 5 are arranged in an array, by comparing the humidity data of sensors at different positions, the seepage point of the seepage water can be further accurately located.

[0039] During installation, the fixing block 9 on the arched frame 2 and the guide frame 8 on the sealing plate 3 slide together to play a pre-positioning role. The pin 10 passes through the guide frame 8 and the fixing block 9 under the elastic force of the spring 11, which can prevent the sealing plate 3 from falling due to the operator's slip during installation, thus facilitating the subsequent tightening of the bolts 4. The inclined surface at one end of the guide frame 8 allows the pin 10 to automatically avoid obstacles during installation, improving the ease of installation.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
