[0025] The following detailed descriptions are all exemplary descriptions, aiming to provide a further detailed description of the present utility model. Unless otherwise specified, all technical terms adopted by the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0026] Embodiment:

[0027] An intelligent monitoring, early warning and control system for a silo provided in this embodiment mainly operates in the normal storage and discharging process of the silo. Due to phenomena such as silo arching, high moisture content in the silo, and silo blockage, it is extremely easy to cause silo collapse accidents. In response to this problem, an intelligent early warning system is proposed to monitor the material conditions in the silo throughout the whole process and in all directions from silo storage to silo opening and discharging, and perform terminal processing on the early warning signals and give timely feedback to prevent casualties and equipment damage caused by accidents. Please refer to Figures 1 - 3, including a silo material flow monitoring device 1 for monitoring abnormal conditions of materials in the silo and at the silo outlet. The silo material flow monitoring device 1 is installed around the silo, and each monitoring signal is connected to the silo warning control system 2 through network cables and cable wires, and is also connected to the plant centralized control room 6 through network cables and cable wires. The silo warning control system 2 is electrically connected to an audible and visual alarm 3, a gate control box 4, and an arch breaking device control box 5 respectively, controlling the audible and visual alarm 3 to send out abnormal signal alarms. At the same time, the gate control box 4 activates the gate closing function, and the gate 7 installed at the silo outlet closes in time to avoid casualties caused by accidents. The arch breaking device 10 is circumferentially fixed to the inner wall of the silo, and the arch breaking device control box 5 starts the silo arch breaking function by receiving the arch breaking signal from the silo warning control system 2, effectively preventing the occurrence of a silo collapse accident caused by silo arching.

[0028] Please refer to Figures 2 - 3 , the silo material flow monitoring and warning device 1 includes a 3D radar monitoring device 101, a camera 102, a liquid level sensor 103, an inclined level switch 104, an impact plate flowmeter 105, and a baffle switch 106. The 3D radar monitoring device 101 is installed at the upper end of the silo inlet. Using software, the movement path of the radar is planned and controlled by multiple robotic arms to image and scan the material type distribution in the silo from different angles, accurately measure the inventory volume, and accurately control the silo content level. When the 3D radar monitoring device 101 monitors that the volume of materials in the silo suddenly becomes smaller or the shape suddenly changes, at this time, the silo warning control system 2 issues a silo collapse signal and transmits the signal to the gate control box 4 and the audible and visual alarm 3. The gate control box 4 controls the gate 7 under the silo to close automatically, and the audible and visual alarm 3 sends out a reminder for the surrounding staff to evacuate. When there is no change in volume or shape, at this time, the silo warning control system 2 issues a silo blockage or arching signal and transmits the signal to the gate control box 4 and the arch breaking device control box 5, controlling the gate 7 to close and starting the arch breaking device 10 at the same time.

[0029] It should be noted that the camera 102 is fixedly installed circumferentially outside the silo. The monitoring range of the camera 102 is the outlet of the chute 8 at the bottom of the silo. The change of the material flow is monitored through the video. When the video shows that the material flow at the outlet suddenly becomes larger, at this time, the silo warning control system 2 issues a signal of silo collapse, and transmits the signal to the gate control box 4 and the audible and visual alarm 3, controls the automatic closing of the gate 7 under the silo, and reminds the surrounding staff to evacuate; when the material flow at the outlet suddenly becomes smaller, at this time, the silo warning control system 2 issues a signal of silo blockage or arching, and transmits the signal to the gate control box 4 and the arch-breaking device control box 5, controls the closing of the gate 7 and starts the arch-breaking device 10 at the same time. The liquid level sensor 103 monitors the water content at the outlet of the silo in real time when the storage gate of the silo remains closed. When the water content exceeds the set value of the liquid level sensor 103, at this time, the silo warning control system 2 issues a signal of silo collapse, and transmits the signal to the gate control box 4 and the audible and visual alarm 3, reminds the surrounding staff to evacuate, and controls the gate 7 under the silo to slowly open a small angle to timely drain the moisture in the silo and avoid casualties caused by sudden opening.

[0030] In addition, the inclined level switch 104 is installed vertically on one side of the chute 8. When the material in the silo rushes out during the discharging process and touches the level switch 104 and tilts, at this time, the silo warning control system 2 issues a signal of silo collapse, and transmits the signal to the gate control box 4 and the audible and visual alarm 3, controls the automatic closing of the gate 7 under the silo, and reminds the surrounding staff to evacuate. The impact plate flowmeter 105 is installed on the bottom plate of the chute 8. By monitoring the change of the impact flow of the material flow on the bottom plate of the chute 8 in real time, when the impact plate flowmeter 105 shows that the material flow suddenly becomes larger, at this time, the silo warning control system 2 issues a signal of silo collapse, and transmits the signal to the gate control box 4 and the audible and visual alarm 3, controls the automatic closing of the gate 7 under the silo, and reminds the surrounding staff to evacuate; when the flow suddenly becomes smaller, at this time, the silo warning control system 2 issues a signal of silo blockage or arching, and transmits the signal to the arch-breaking device control box 5 to start the arch-breaking device 10. The baffle switch 106 is installed at the outlet of the chute 8. When a silo collapse accident occurs and the escaped material pushes the baffle switch 106, at this time, the silo warning control system 2 transmits the signal of silo collapse to the gate control box 4 and the audible and visual alarm 3, controls the automatic closing of the gate 7 under the silo, and reminds the surrounding staff to evacuate.

[0031] In this embodiment, the plant-wide control room 6 is electrically connected to the silo early warning control system 2. When any device in the silo monitoring device 1 detects an abnormal signal, the silo early warning control system 2 will transmit the signal to the plant-wide control room 6. The staff can observe the material flow in the silo in real time in the control room 6 to ensure the safety of the personnel and grasp the material situation in the silo. In the silo monitoring and early warning device 1, two or three devices can be selected for monitoring according to different working conditions, and the specific installation position of the device can be determined according to different working environments to ensure the reliable and effective operation of the device. When any device detects a signal of silo collapse or silo blocking and arching, the silo early warning control system 2 will control the gate 7 to work or start the arch breaking device 10, and control the sound and light alarm 3 to send out a danger signal until the safety hazard is eliminated and the gate 7 is fully opened to continue discharging. The silo arch breaking device 10 is installed within 1-2m of the intersection of the silo cone section and the straight section. When the silo early warning control system 2 sends a silo arching signal, the silo gate 7 is controlled to be closed, and the arch breaking device 10 is opened at the same time. Its working principle is that when the arch breaking device 10 receives the arch breaking signal, the hydraulic push rod is started to extend, the material in the vibrating silo falls, and the arch breaking function is realized. The silo material flow monitoring device 1 and the silo early warning control system 2 both have power failure protection measures. When a power failure occurs, the lower gate 7 of the silo is automatically closed.

Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive.
