DETAILED DESCRIPTION
[0016] The utility model will be further described below in combination with the drawings and specific embodiments.
[0017] As Figs. 1-2 shown, a mine approach filling slurry level multi-point continuous detection and sound-light alarm system, including power supply 1, power supply 1 is connected to double circuit breaker 2, double circuit breaker 2 is connected with first intermediate relay 6 and second intermediate relay 7, and the input end of first intermediate relay 6 and the output end of second intermediate relay 7 are connected with PLC controller 8, and the output end of PLC controller 8 is connected with first material level sensor 9, second material level sensor 10, third material level sensor 11 and multi-loop digital display instrument 12 in turn, and the output end of PLC controller 8 is also connected with fifth intermediate relay 16, and the output end of fifth intermediate relay 16 is also connected with electric siren 17.
[0018] The output end of double circuit breaker 2 is connected with first signal lamp 3, the output end of PLC controller 8 and fifth intermediate relay 16 are connected with fourth intermediate relay 15 in parallel, and the output end of fourth intermediate relay 15 is also connected with second signal lamp 4.
[0019] The both ends of first signal lamp 3 are connected with button 5, and the button 5 close to the side of second intermediate relay 7 is also connected with first intermediate relay 6.
[0020] The output end of PLC controller 8 is connected with single-loop digital display instrument 13, and the output end of PLC controller 8 is also connected to third intermediate relay 14, and third intermediate relay 14 is connected with second signal lamp 4 and electric siren 17.
[0021] First material level sensor 9, second material level sensor 10 and third material level sensor 11 are installed in different sections of the planned filling approach, for real-time detection of the material level of filling slurry in different sections of the filling approach and the estimated amount of slurry required to fill the remaining space when approaching the end of filling, which is connected with PLC controller 8 and transmits the detected signal to PLC controller 8.
[0022] The first material level sensor 9, the second material level sensor 10 and the third material level sensor 11 are arranged along the direction of the filling path, and the distances are 2m, 8m and 14m from the filling path wall 2 respectively, and the reason for arranging the multiple sensors at different positions is that the filling slurry flow surface is an inclined surface, the material levels at different positions are different, and the multiple sensors need to be arranged to detect the material level data so as to accurately estimate how much cubic filling slurry is needed for the unfilled space through calculation and comparison, since the filling slurry mixing station is on the ground and the filling path is underground, and the length of the filling pipeline is about 1800m, after the mixing station stops, there is still about 20m3 of filling slurry in the mixing barrel and the filling pipeline on the ground that needs to flow into the filling path, therefore, when the material level detection system estimates that 30m3 of filling slurry is still needed, the control PLC controller 8 outputs an alarm signal to remind the filling supervisor to contact the ground mixing station to stop.
[0023] In the specific application, before starting filling, the first material level sensor 9, the second material level sensor 10 and the third material level sensor 11 are arranged along the direction of the filling path, and are arranged in the holes reserved in the roof of the filling path at a distance of 2m, 8m and 14m from the filling path wall 2 respectively, when starting filling, the AC 220V power supply 1 is connected, the double circuit breaker 2 is closed, the system start button 5 is pressed, the system enters the real-time detection state, the first material level sensor 9, the second material level sensor 10 and the third material level sensor 11 three material level detection sensors transmit the slurry material level detection data to the PLC controller 8 in real time, on the one hand, the PLC controller 8 alternately displays the material levels of the first material level sensor 9, the second material level sensor 10 and the third material level sensor 11 three points on the multi-loop digital display instrument 12 through the analog output port, on the other hand, when the third material level sensor 11 detects that the material level is less than 0.2m, the PLC controller 8 estimates the amount of filling slurry needed for the remaining space through the slurry material levels of the first material level sensor 9, the second material level sensor 10 and the third material level sensor 11 three points through operation, and displays the estimated amount of filling slurry on the single-loop digital display instrument 13 through the analog output port, when the material level detection system estimates that 30m3 of filling slurry is still needed, the PLC controller 8 digital quantity output point acts, the fourth intermediate relay 15 and the fifth intermediate relay 16 act, the second signal lamp 4 is lighted, the electric siren 17 is powered on to alarm, reminding the on-site filling operator to observe the system digital display instrument display data in time, when the estimated filling amount displayed is equal to 20m3, the filling mixing station is contacted to stop, thereby avoiding the filling slurry running and the filling path wall collapse accident caused by not stopping in time, effectively reducing the phenomenon of overflow filling slurry polluting the operation site, obviously improving the safety level of the operation site, therefore, the system has good practicability.
