AI Technical Summary
The existing online monitoring system for tailings dams cannot promptly shut down the overflow culvert valves, leading to tailings leakage when the overflow well collapses, posing a safety hazard.
The system employs a linkage mechanism consisting of tilt sensors, signal transmitters and acquisition units, a central processing controller, and culvert valve control devices to monitor the tilt of the overflow well in real time. When the overflow well exceeds the tilt limit, the valve is automatically closed, and an audible and visual alarm device is used to alert staff.
It enables the valve to be closed immediately when the overflow well tilts, preventing tailings leakage and improving safety and preventative treatment capabilities.

TECHNICAL FIELD
[0001] The utility model relates to mining technical field especially is related to a tailing pond overflow well inclination alarm linkage system. BACKGROUND
[0002] The overflow well is established at the bottom of the tailing pond, and the water content of the base soil layer is large, so the overflow well is prone to tilt and collapse. In the current popular tailing pond online monitoring system, the monitoring of the overflow well is relatively single, and only the state of the overflow well can be monitored, and linkage with other equipment of the tailing pond cannot be realized, and on-site personnel are still needed to judge and handle when abnormal conditions occur. Recently, a domestic mining enterprise caused the tailing to leak due to the collapse of the overflow well, and the tailing washed away the road and caused large-area pollution. The reason is that after the overflow well collapses, the online monitoring system gives an alarm, but the valve of the overflow culvert is not closed in time, and the on-site personnel still need to waste a reaction time after learning of the alarm, which finally leads to a large amount of tailing leakage. Therefore, the existing tailing pond online monitoring system needs to be improved. SUMMARY

[0006] Further improvement of the technical scheme, the tailing pond overflow well inclination alarm linkage system further comprises an audible and visual alarm device, the output end of the central processing controller is connected with the audible and visual alarm device, and the audible and visual alarm device starts to alarm when the overflow well tilts.
[0007] Further improvement of the technical scheme, the audible and visual alarm device and the central processing controller are arranged in the central control room.
[0008] Further improve technical solutions, the tilt sensor is connected with the signal transmission collector through a wired transmission line, the signal transmission collector transmits signals to the central processing controller through a wireless transmission network, and the central processing controller outputs instructions to the culvert valve control device through the wireless transmission network.
[0009] After the above technical solutions are implemented, compared with the background art, the present application has the following beneficial effects:
[0010] The tailing pond overflow well tilt alarm linkage system is provided with a tilt sensor, a signal transmission collector, a central processing controller and a culvert valve control device, and once the overflow well exceeds the tilt limit value, the tailing pond overflow well tilt alarm linkage system immediately closes the valve of the overflow culvert, thereby avoiding tailing leakage.

[0014] Referring to the drawings Figure 1 A tailing pond overflow well tilt alarm linkage system, comprising an overflow culvert 3 in communication with the overflow well 2, and a valve 5 installed at the outlet of the overflow culvert 3.
[0015] In order to solve the problems in the background art, the tailings pond overflow well inclination alarm linkage system further comprises an inclination sensor 4, a signal transmission collector, a central processing controller and a culvert valve control device. Limited by the distance on site, the inclination sensor 4 and the signal transmission collector are arranged at the top of the overflow well 2, the central processing controller is arranged in the central control room 6, and the culvert valve control device is arranged near the valve 5. The inclination sensor 4 is connected with the signal transmission collector through a wired transmission line, the signal transmission collector transmits signals to the central processing controller through a wireless transmission network, and the central processing controller outputs instructions to the culvert valve control device through the wireless transmission network.
[0016] The signal transmission collector is used for converting the electrical signals output by the inclination sensor 4 into a data format that can be transmitted and received by the wireless transmission network and the automatic control system. The electrical signals output by the inclination sensor 4 are transmitted to the central processing controller after being processed by the signal transmission collector, and the central processing controller has the ability of data analysis and processing.
[0017] The inclination of the overflow well 2 is a precursor to the collapse of the overflow well 2. After the wind interference is removed, once the overflow well 2 exceeds a certain inclination angle, the central processing controller can determine that the overflow well 2 is likely to collapse, at which time the central processing controller immediately outputs instructions to the culvert valve control device through the wireless transmission network to close the valve 5 at the outlet of the overflow culvert 3. In this way, the tailings are enclosed in the overflow culvert 3 and cannot leak out.
[0018] In order to alert the staff, the tailings pond overflow well inclination alarm linkage system further comprises an audible and visual alarm device, which is arranged in the central control room 6 and connected with the central processing controller through a wired transmission line. When the overflow well 2 inclines, the audible and visual alarm device starts to alarm and alert the staff in the central control room 6.
[0019] As can be seen from the above, the tailings pond overflow well inclination alarm linkage system is provided with the inclination sensor 4, the signal transmission collector, the central processing controller and the culvert valve control device. Once the overflow well 2 exceeds the inclination limit value, the tailings pond overflow well inclination alarm linkage system immediately closes the valve 5 of the overflow culvert to prevent the tailings from leaking out.
[0020] The parts not described in detail are prior art. Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the protection scope of the utility model is defined by the appended claims and their equivalents.
