Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel structure monitoring, and in particular relates to a tunnel water seepage monitoring device. Background Art

[0002] Tunnels are an important part of modern transportation systems. Changes in tunnel structures can bring huge risks to tunnels, among which water seepage in settlement joints is an important sign of changes in tunnel structures.

[0003] The Chinese patent with the publication number CN216077223U discloses an intelligent monitoring and alarm device for tunnel engineering, including two support plates, a first curved plate and a second curved plate are fixedly connected between the two support plates, the first curved plate is located above the second curved plate, a plurality of water buckets are evenly fixedly connected to the first curved plate, the bottom end of the water bucket passes through the lower surface of the first curved plate and is located above the second curved plate, and the upper surface of the second curved plate is evenly fixedly connected with fixed columns corresponding to the water buckets. Water droplets passing through the inner wall of the tunnel fall onto the first metal plate. Since water is a conductor, the water droplets will connect the first metal plate with the second metal plate, so that the alarm light will turn on. The position of the alarm light can determine the area of ​​water seepage on the top wall of the tunnel, so that only a small amount of water droplets are needed to turn on the alarm light, and the alarm sensitivity is high.

[0004] However, in actual use, although the water droplets can connect the first metal plate and the second metal plate to perform a conductive function, since the water droplets seeping out of the tunnel may contain a variety of ions, electrolysis and ionization may occur when power is turned on, which may cause the metal plate to be burned or produce dangerous gases, thereby affecting the safety of use or the service life of the device. That is, the device has poor safety when used and a short service life. Utility Model Content

[0005] The utility model aims to provide a tunnel water seepage monitoring device to solve the problems of poor safety and short service life of the prior art mentioned above.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tunnel water seepage monitoring device, comprising

[0007] The arc plate group includes a first arc plate, a second arc plate and a plurality of connecting rods, wherein the bottom of the first arc plate is provided with a plurality of connecting rods at intervals, the second arc plate is fixed to the bottom of the connecting rods, and support plates are installed on both sides of the second arc plate;

[0008] The monitoring mechanism includes a monitoring unit, which includes a collecting bucket, a collecting cylinder, a limiting cylinder, a weight amplification component, a trigger button and an alarm light. The collecting bucket is fixed on the first arc plate, and the bottom of the collecting bucket extends between the first arc plate and the second arc plate. The limiting cylinder is fixed on the top of the second arc plate. The lower end of the collecting cylinder is slidably inserted in the limiting cylinder, and the top of the collecting cylinder corresponds to the bottom of the collecting bucket. The trigger button is installed on the second arc plate, and the weight amplification component is installed on the second arc plate, and one end of the weight amplification component corresponds to the collecting cylinder, and the other end of the weight amplification component corresponds to the trigger button. The alarm light is installed on the bottom of the second arc plate.

[0009] The principle and effect of this technical solution:

[0010] 1. The seepage water on the top of the tunnel is collected through the collecting bucket, thereby increasing the collection surface when the water droplets penetrate, and the water droplets in the collecting bucket are collected and stored through the collecting tube, avoiding the direct contact of the water droplets with the electronic components, thereby avoiding the occurrence of electrolysis, ionization, etc., and ensuring safety during use.

[0011] 2. The weight of the water droplets collected in the collection tube is amplified by the weight amplification component, so that the trigger button can be pressed and activated by the weight amplification component when there are fewer water droplets in the collection tube, thereby causing the alarm light to sound, which reduces the amount of water droplets that need to be collected and improves the detection accuracy.

[0012] 3. Through the arrangement of the first arc plate, the second arc plate, the connecting rod and the supporting plate, the monitoring mechanism can be close to the top of the tunnel wall, thereby collecting water droplets at a close distance.

[0014] The principle and effect of the technical solution are as follows: by making the length of the amplifying plate on the side close to the limiting cylinder greater than the length of the amplifying plate on the side close to the side plate, and the amplifying plate is hinged on the fixing frame, so that an amplifying lever is formed between the amplifying plate and the fixing frame, and the collecting cylinder is abutted against the amplifying plate, so that after the water droplets are collected in the collecting cylinder, the weight of the water droplets can be amplified by the amplifying plate to press the trigger button, so that the trigger button is pressed, so that the alarm light alarms, and the weight of the water droplets inside the collecting cylinder is amplified by the weight amplifying component, thereby reducing the amount of water droplets required for the device to monitor water seepage, thereby improving the safety of the equipment. The monitoring accuracy is improved; at the same time, through the setting of the initial position spring, when no water droplets are collected in the collecting tube, one end of the amplifying plate will be tightly against the bottom of the collecting tube, and the other end will be away from the trigger button, thereby avoiding the occurrence of accidental touch; and by setting the trigger button at the top of the inner side of the "7"-shaped side plate, even if the device detects serious water seepage and water droplets overflow the collecting tube and enter the second arc plate, the overflowing water droplets and water flow will not contact the trigger button, thereby preventing the trigger button from being corroded or interfered by water droplets, thereby ensuring the stability and reliability of the device when in use.

[0015] The utility model is further configured that water-absorbing cotton is placed in the collecting tube.

[0016] The principle and effect of this technical solution: through the setting of absorbent cotton, the moisture can be temporarily locked after entering the collection tube, and it is convenient for subsequent workers to deal with the moisture in the collection tube. The water droplets in the collection tube can be eliminated by taking out the absorbent cotton, thereby restoring the collection tube to its initial position, and then the alarm light will not sound.

[0017] The utility model is further configured as follows: there are a plurality of monitoring units, which are distributed at intervals along the circumference of the first arc plate.

[0018] The principle and effect of this technical solution: through the setting of multiple monitoring units, the device can simultaneously detect multiple locations in a tunnel when monitoring water seepage in the tunnel, thereby improving the monitoring accuracy.

[0019] The utility model is further configured as follows: it also includes a lifting mechanism, the lifting mechanism includes two lifting components respectively arranged on the support plates on both sides, the lifting components include a lifting motor, a lifting screw and a lifting block, a lifting slot is opened on the support plate, the lifting screw is rotatably installed in the lifting slot, the lifting block is slidably fitted in the lifting slot, and the lifting block is threadedly mounted on the lifting screw, the side wall of the second arc plate is connected to the lifting block, the lifting motor is fixed to the bottom of the support plate, and the rotating end of the lifting motor is connected to the bottom of the lifting screw.

[0020] The principle and effect of this technical solution: the lifting motor drives the lifting screw to rotate, so that the lifting screw drives the lifting block to move up and down along the lifting slot of the support plate, thereby driving the arc plate group to adjust the height. By controlling the height of the arc plate group, it is convenient for the staff to carry out subsequent maintenance, replacement and overhaul of the monitoring mechanism. At the same time, by lowering the height of the arc plate group, the center of gravity of the device is lowered, which is convenient for transportation and carrying.

[0021] The utility model is further configured as follows: moving wheels are installed at the bottom of the supporting plate.

[0022] The principle and effect of the technical solution: the setting of the moving wheels makes it easy for monitoring personnel to move the position of the monitoring device, so that the monitoring device can monitor different places in the tunnel. BRIEF DESCRIPTION OF THE DRAWINGS
