Description

Technical Field

[0001] The utility model relates to the technical field of tunnel monitoring devices, in particular to a tunnel leakage monitoring device. Background Art

[0002] In the process of highway construction, there are sometimes some mountains blocking the way. In order to save construction costs, tunnels are usually opened directly in the mountains and reinforced with composite concrete linings. Although geotextiles and waterproof boards are installed at the joints of adjacent tunnel linings, due to the degradation of the rock and soil environment, especially the effect of fissure water, as the structure functions, leakage is likely to occur during use, and monitoring devices are needed to monitor the adjacent lining joints.

[0003] The patent specification with the announcement number CN219161581U discloses a tunnel water leakage monitoring device, which includes at least two sections of tunnel main bodies, and a monitoring device for monitoring water leakage is arranged on the inner wall of the joint between the two sections of the tunnel main bodies, and the monitoring device includes a shell cover, and both ends of the bottom of the shell cover are provided with a liquid level sensor body for liquid level monitoring and a sealing plug for leaking water discharge. The utility model arranges a monitoring device composed of a shell cover, a liquid level sensor body, and a data processor body on the inner wall of the tunnel joint, thereby performing real-time monitoring of water leakage at the tunnel joint, replacing the regular monitoring used in the prior art, thereby ensuring the timeliness of the staff's understanding of the water leakage at the tunnel joint, and reducing the workload of the staff for regular monitoring.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned tunnel water leakage monitoring device has the following problems: the device collects water leaking from the connection between the two tunnel bodies through a shell cover, and monitors the liquid level in the shell cover through a liquid level sensor body. Since tunnels are usually built in mountainous areas, vehicles often bring gravel and dust into the tunnel. When the gravel and dust contact the liquid level sensor body, the liquid level sensor body is easily impacted or damaged by internal dust, which reduces the service life of the liquid level sensor body, thereby reducing the monitoring efficiency of the device for tunnel leakage. In view of this, a tunnel leakage monitoring device is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a tunnel leakage monitoring device.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tunnel leakage monitoring device, including a tunnel lining, a shell cover is provided on the inner side of the tunnel lining, a liquid level sensor body is fixedly provided on one side of the shell cover, a data processor body is fixedly provided on the inner side of the shell cover, a fixing ring is provided on the outer side of the liquid level sensor body, a filter is fixedly provided on the inner side of the fixing ring, a plurality of support rods are fixedly provided on one side of the fixing ring, a connecting ring is provided at one end of the plurality of support rods, one side of the connecting ring is fixedly connected to one end of the plurality of support rods respectively, a plurality of protective rods are fixedly provided on the inner side of the connecting ring, two mounting seats are fixedly provided on the side of the fixing ring, bolts are provided inside the two mounting seats, and the sides of the two bolts are threadedly connected to one side of the shell cover.

The screws facilitate fixing the fixing seats and the tunnel lining together.

[0009] As a further description of the above technical solution: two limit seats are provided on the inner side of the tunnel lining, and the side surfaces of the two limit seats are respectively fixedly connected to the side surfaces of four fixing seats, and the fixing seats facilitate fixing the limit seats and the lining together.

[0010] As a further description of the above technical solution: a slide groove is provided inside the two limit seats, and a slider is slidably connected inside the two slide grooves. One side of the two sliders is fixedly connected to the inner side of the shell cover, and the limit seat facilitates limiting the slider.

Through design coordination, the liquid level sensor body is protected by a fixing ring, a support rod, a connecting ring and a protection rod, which can prevent large-particle gravel from directly hitting the liquid level sensor body and causing damage. When dust and small-particle gravel approach the liquid level sensor body, the dust and small-particle gravel are blocked by a metal filter, thereby improving the protection and dustproof ability of the liquid level sensor body. The gaps between the mesh of the filter and the support rod and the protection rod do not affect the contact between the air and the liquid level sensor body, so that the liquid level sensor body still has a high heat dissipation efficiency, so that the device is convenient for improving the protection and dustproof ability of the liquid level sensor body without affecting the heat dissipation of the liquid level sensor body, and is convenient for improving the service life of the liquid level sensor body, thereby improving the monitoring efficiency of the device for tunnel lining leakage;

At this time, the maintenance personnel can directly repair the connection of the tunnel lining. When the maintenance is completed, the two forward and reverse motors are reversed to drive the shell cover to move in the opposite direction, so that the shell cover seals the connection of the tunnel lining, so that the device can easily drive the shell cover to move automatically, so that there is no need to disassemble the shell cover when repairing the tunnel lining leakage, which is convenient for saving manpower and improving the efficiency of repairing the connection of the tunnel lining.
