Description

Technical Field

[0001] This invention relates to the field of karst tunnel technology, specifically to a karst tunnel water inflow monitoring device. Background Technology

[0002] With the continuous development of the national economy, tunnels are increasingly needed in the construction of infrastructure such as railways and highways. Since tunnels are usually built inside mountains, safety is always the top priority during the construction process. Therefore, at the beginning of tunnel construction, it is necessary to explore the water seepage situation inside the tunnel. Only after understanding the water ingress situation can subsequent processing and maintenance technology plans be implemented. Therefore, it is necessary to design a karst tunnel water inflow monitoring device.

[0003] Existing water flow monitoring devices have the following drawbacks during use: 1. The internal structure of existing water flow monitoring devices is relatively simple, which can lead to the accumulation of external impurities and silt at the inlet, causing blockages and affecting the accuracy of the detection. Furthermore, frequent manual cleaning and unclogging by operators is required, increasing the workload and reducing the practicality and convenience of the device. 2. Due to the simple internal structure, most existing detection devices can only monitor water level, and are not convenient for providing immediate alerts at a specified water level, posing certain safety hazards and reducing the flexibility and safety of the device. Summary of the Invention

[0034] As a preferred embodiment, the impact assembly includes a pressing rod 11, a spring 3, an impact rod 4, and a pressing block 13. Two sets of pressing blocks 13 and pressing rods 11 are provided. The two sets of pressing blocks 13 are located at the top of the two sets of rotating rods 8 on opposite sides. The two sets of pressing rods 11 are located on both sides of the top of the mounting groove 1 and extend into the interior of the filter screen plate 7. The pressing rods 11 and pressing blocks 13 cooperate with each other. At the bottom of the two sets of pressing rods 11 on opposite sides, impact rods 4 that cooperate with the filter screen plate 7 are provided. Springs 3 connected to the filter screen plate 7 are sleeved at the middle position of the outer side of the two sets of pressing rods 11, which further enhances the anti-clogging function inside the filter screen plate 7.

[0035] As a preferred embodiment, the top of both ends of the monitoring chamber 2 is provided with through slots, and the through slots are connected to the inside and outside of the monitoring chamber 2, which facilitates the rotation of the threaded rod 15 by the operators and also facilitates the rise of water volume.

[0036] As a preferred embodiment, the top of the outer side of the threaded rod 15 is uniformly provided with a handle, and the outer side of the handle is covered with an anti-slip sleeve to prevent slippage during rotation.

[0037] As a preferred embodiment, the monitoring chamber 2 is provided with guide grooves and limiting slide rods on both sides, and the guide grooves and limiting slide rods cooperate with the internal threaded sleeve 14 and the float 6 respectively, so as to facilitate the limiting movement of the internal threaded sleeve 14 and the float 6.

[0038] As a preferred embodiment, L-shaped limiting blocks are provided on both sides of the top of the mounting groove 1, and the L-shaped limiting blocks cooperate with the pressing rod 11 to improve the stability of the pressing rod 11 during installation and fixing.

[0039] As a preferred embodiment, the bottom ends of the two sets of pressing blocks 13 that are far apart from each other and the top ends of the two sets of pressing rods 11 that are far apart from each other are provided with guide slopes, and the two sets of guide slopes cooperate with each other to facilitate the pressing blocks 13 to push the pressing rods 11 downward through the guide slopes when they rotate with the rotating rod 8.

[0040] As a preferred embodiment, the monitoring chamber 2 has a liquid level observation window on one side of its front, and the liquid level observation window has uniformly distributed scale lines on one side of its front. The scale lines cooperate with the internal threaded sleeve 14 to facilitate the operator's subsequent adjustment and observation work.

[0041] As a preferred embodiment, the output end of the servo motor 18 is provided with a rotating shaft connected to the monitoring chamber 2, and the rotating shaft cooperates with the incomplete gear 20 to facilitate the installation and rotation of the incomplete gear 20.

[0042] Example 1, such as Figure 1-4As shown, when the monitoring and prompting component is in operation, the operator can first rotate the threaded rod 15 through the through groove at the top of one end of the front of the monitoring chamber 2. The rotation of the threaded rod 15 can drive the internal threaded sleeve 14 to move on its surface. Then, the internal threaded sleeve 14 can be moved to the designated position through the liquid level observation window and scale line at one end of the front of the monitoring chamber 2. When the water enters the monitoring chamber 2 and gradually rises, the buoyancy of the float 6 and the rise of the water level can drive the float 6 to slide upward outside the limit rod 9. Then, the float 6 drives the metal contact block 10 to move upward and make contact with the metal contact block 12. The contact can then turn on the prompt light 22 so that the prompt light 22 can remind the operator to work, thereby improving the safety of the device in the later use.

[0043] Example 2, as Figure 1-4 As shown in Figure 6, when the impact assembly is working, the rotating rod 8 drives the pressing block 13 to rotate. Then, through the guide slope design of the pressing block 13 and the pressing rod 11, the pressing block 13, during rotation, pushes the pressing rod 11 down inside the mounting groove 1 to compress the spring 3. This causes the pressing rod 11 to move the impact rod 4 away from contact with the filter screen 7. Then, when the coil spring 16 drives the rotating rod 8 and the above components to return to their original position, the resistance between the pressing block 13 and the pressing rod 11 is released. Then, the elastic restoring force of the spring 3 drives the pressing rod 11 to return to its original position, causing the impact rod 4 to return to its original position and impact the filter screen 7. At this time, the vibration force generated by the impact can again clear the inside of the filter screen 7, effectively preventing blockage inside.

[0044] Working principle: When the device is in use, the operator can first move and install the device to the designated location. Then, through the operation of the monitoring and prompting component, the water level at any height can be monitored and prompted. Then, the water inside the tunnel can enter the monitoring chamber 2 through the bottom of the installation tank 1. At this time, the filter screen 7 designed at the bottom of the installation tank 1 can block and filter impurities and silt in the water. When the water rises to the designated position, the water level can be prompted through the operation of the monitoring and prompting component, which makes it easier for the staff to take protective measures later.

[0045] Simultaneously, the servo motor 18 drives the incomplete gear 20 to rotate. When the incomplete gear 20 meshes with the incomplete gear 17, it rotates to a designated position. This meshing causes the rotating rod 8 to rotate inside the fixed block 21, stretching the coil spring 16. The rotating rod 8 then drives the cleaning rod 5 to rotate at the bottom of the filter screen 7, cleaning impurities and sludge from the bottom of the filter screen 7 to prevent clogging. When the incomplete gear 20 continues to rotate and disengages from the incomplete gear 17, the elastic restoring force of the coil spring 16 drives the rotating rod 8 and its components to return to their original position, ensuring continuous cleaning. During the rotation of the rotating rod 8, the impact component is also driven to impact, further improving the anti-clogging efficiency of the filter screen 7, ensuring normal water flow, and enhancing monitoring accuracy.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
