Description

Technical Field

[0001] The utility model relates to the technical field of mine fire early warning, in particular to a control system for early warning and fire extinguishing. Background Art

[0002] Coal mine transportation devices are the main transportation equipment for coal mine production. The transportation devices are mainly belt conveyors. The working efficiency and safety of belt conveyors are crucial to the safe production of coal mines. Belt conveyors often catch fire due to jamming, friction, deviation, coal piling, etc. during transportation. With the development of technology, although the fire warning and fire extinguishing devices of belt conveyors are becoming more and more perfect, the belt conveyors, fire warning and fire extinguishing devices are independent of each other, so that the belt conveyors and fire warning devices are separated from the control of the belt conveyors, resulting in disaster information directly sending alarm signals to the operator through the alarm, and the operator completes the belt stopping action. Even many alarm information need to be sent to the site for inspection and confirmation before deciding to start and stop the belt conveyor. There are too many confirmation points in this process, and it takes too long. Since the belt conveyor itself runs at high speed, the belt has a long braking time due to inertia. Many fire accidents actually occur during the process of alarm, confirmation, and shutdown, which leads to the spread and expansion of the fire. If we can automatically shut down the belt conveyor as soon as possible, we can reduce the impact of the disaster or even avoid it. Utility Model Content

[0025] Coal mine transportation devices are the main transportation equipment for coal mine production. The transportation devices are mainly belt conveyors. The working efficiency and safety of belt conveyors are crucial to the safe production of coal mines. Belt conveyors often catch fire due to jamming, friction, deviation, coal piling, etc. during transportation. With the development of technology, although the fire warning and fire extinguishing devices of belt conveyors are becoming more and more perfect, the belt conveyors, fire warning and fire extinguishing devices are independent of each other, so that the belt conveyors and fire warning devices are separated from the control of the belt conveyors, resulting in disaster information directly sending alarm signals to the operator through the alarm, and the operator completes the belt stopping action. Even many alarm information need to be sent to the site for inspection and confirmation before deciding to start and stop the belt conveyor. There are too many confirmation points in this process, and it takes too long. Since the belt conveyor itself runs at high speed, the belt has a long braking time due to inertia. Many fire accidents actually occur during the process of alarm, confirmation, and shutdown, which leads to the spread and expansion of the fire. If we can automatically shut down the belt conveyor as soon as possible, we can reduce the impact of the disaster or even avoid it.

[0026] Reference Figure 1 As shown, in order to solve the above technical problems, the present application provides a control system for early warning and fire extinguishing, including a conveying device 10, a sensor device 20, a start-stop device 30 and a control device 40. The sensor device 20 is arranged on the conveying device 10, and the sensor device 20 includes at least one of a flame sensor 21, a carbon monoxide sensor 22, a smoke sensor 23 and a temperature-sensitive optical cable 24. The start-stop device 30 is electrically connected to the conveying device 10, and the start-stop device 30 includes a starter and stopper 32, and the conveying device 10 is started and stopped by the starter and stopper 32. The control device 40 is electrically connected to the start-stop device 30 and the sensor device 20, respectively, and the control device 40 is used to control the starter and stopper 32 to start and stop the conveying device 10 according to the information of the sensor device 20.

[0027] The conveying device 10 is used to transport the minerals. The conveyor belt 11 used in the mineral field is stronger and more durable than the conveyor belt 11 used in general industry.

[0028] The flame sensor 21 in the sensing device 20 is used to monitor the fire source information; the carbon monoxide sensor 22 is used to monitor the information of carbon monoxide, including the concentration and content; the smoke sensor 23 is used to monitor the concentration of smoke; and the temperature sensing optical cable 24 is used to monitor the real-time temperature or temperature change information.

[0029] The starter / stopper 32 includes one of a remote circuit breaker and a vacuum electromagnetic starter.

[0030] In the present embodiment, when a fire occurs in the conveying device 10, the sensor device 20 can transmit the fire information to the control device 40, and the control device 40 sends a command to the starter and stop device 32 to control the starter and stop device 32 to stop the conveying device 10, thereby reducing the expansion or spread of the fire caused by jamming, friction, deviation, coal piling, etc. during the transportation process of the conveying device 10, and can even stop the conveying device 10 when the fire just occurs or when there is a tendency for a fire to occur, so that the fire is automatically extinguished or the occurrence of a fire is avoided.

[0031] In some embodiments, the start-stop device 30 further includes a programmable logic controller 31 (PLC), which stores instructions for executing logic operations, sequential control, timing, counting, and arithmetic operations. The PLC is disposed between the control device 40 and the start-stop device 32, and is electrically connected to both of them. The start-stop device 32 can receive the instructions of the PLC to control the connection and disconnection of the current, so as to control the start and stop of the conveying device 10.

[0032] In some embodiments, the control system for early warning and fire extinguishing also includes an electric ball valve 50 and a fire extinguishing device 60. The electric ball valve 50 is electrically connected to the control device 40 and the fire extinguishing device 60 respectively. The fire extinguishing device 60 is arranged in the fire extinguishing area of ​​the conveying device 10. The control device 40 sends an instruction to the electric ball valve 50 to open the fire extinguishing device 60 in the fire extinguishing area.

[0033] The electric ball valve 50 is a valve that rotates around the axis of the valve stem according to the movement of the valve disc, and is a pipeline pressure element for industrial automation process control. The fire extinguishing device 60 can generally extinguish the fire by spraying water, spraying dry powder, or extinguishing the fire by mud and sand.

[0034] The fire extinguishing device 60 mainly includes a sprinkler fire extinguisher 61 and a dry powder fire extinguisher 62. The dry powder fire extinguisher 62 is mainly used to extinguish the driving roller and motor of the conveying device 10; the sprinkler fire extinguisher 61 is distributed above and below the conveyor belt 11, and is used to extinguish the entire conveying device 10.

[0035] The fire extinguishing device 60 is arranged in the fire extinguishing area of ​​the conveying device 10. The fire extinguishing area selects the corresponding area according to the fire extinguishing method of the fire extinguishing device 60. When the fire is extinguished by water spraying and dry powder spraying, the fire extinguishing device is installed above the conveying device and hung on the top beam or bracket of the tunnel. The spraying device is mainly used for belt fire extinguishing along the conveyor, and the powder spraying fire extinguishing device is mainly used for extinguishing the electric components such as the driving and brake motors of the belt conveyor. According to the actual situation and needs, the spraying fire extinguishing device can also be installed on the bracket beam between the upper and lower belts.

[0036] When the sensor device 20 detects a fire, the control device 40 controls the electric ball valve 50 to open the fire extinguishing device 60, which can reduce the time for manual confirmation and reduce the risk of fire spreading and expanding.

[0037] In some embodiments, the conveying device 10 includes a conveyor belt 11, rollers 12, a transmission device (not shown in the figure) and a brake device (not shown in the figure). The conveyor belt 11 is arranged on the rollers 12. The transmission device drives the rollers 12 to rotate and then drives the conveyor belt 11 to rotate. The brake device can brake and stop the conveyor belt 11. The rollers 12 can be driven by a power device to drive the conveyor belt 11 to rotate to transport minerals. The brake device can also be driven by the power device to brake the conveyor belt 11.

[0038] In some embodiments, the flame sensor 21, the carbon monoxide sensor 22 and the smoke sensor 23 are arranged outside the conveyor belt 11 to obtain information about the flame, carbon monoxide and smoke; the temperature-sensitive optical cable 24 is arranged inside the conveyor belt 11, and the temperature-sensitive optical cable 24 extends from one side of the conveyor belt 11 to the other side to obtain information about the temperature change inside the conveyor belt 11. When a fire occurs, the flame, carbon monoxide and smoke can all circulate into the air, or can be easily seen in the visible range. Therefore, the flame sensor 21, the carbon monoxide sensor 22 and the smoke sensor 23 are arranged outside the conveyor belt 11, which can also reduce the internal space of the conveyor belt 11 and facilitate installation and maintenance. The temperature-sensitive optical cable 24 needs to monitor the real-time temperature of the conveyor belt 11. In order to improve the accuracy of monitoring, the temperature-sensitive optical cable 24 needs to be arranged inside the conveyor belt 11 to maintain a closer distance to the conveyor belt 11. Therefore, the above design can facilitate installation, maintenance and improve the accuracy of monitoring.

[0039] In some embodiments, the control system for early warning and fire extinguishing further includes a temperature measuring host 70, which is electrically connected to the temperature sensing optical cable 24, the control device 40 and the electric ball valve 50 respectively, and the temperature information obtained by the temperature sensing optical cable 24 is transmitted to the control device 40 via the temperature measuring host 70, and the control device 40 or the temperature measuring host 70 can issue instructions to the electric ball valve 50 to open the fire extinguishing device 60. Thus, the temperature information of the temperature sensing optical cable 24 can be analyzed by the temperature measuring host 70, and the analyzed information can be directly transmitted to the control device 40, or directly transmitted to the electric ball valve 50 to achieve fire extinguishing, which can reduce the time of manual confirmation and quickly handle the fire after accurate analysis.

[0040] In some embodiments, the conveyor belt 11 includes an upper conveyor belt 101 and a lower conveyor belt 102, the upper conveyor belt 101 is connected to the lower conveyor belt 102, and the upper conveyor belt 101 and the lower conveyor belt 102 are respectively located on both sides of the radial direction of the roller 12; the temperature sensing optical cables 24 are configured as at least two, two temperature sensing optical cables 24 are arranged on the lower conveyor belt 102 in the radial direction, and two temperature sensing optical cables 24 are arranged on both sides of the roller 12 in the transverse direction, and the radial direction is perpendicular to the transverse direction. In this way, the temperature of the conveyance can be more comprehensively monitored, so as to determine the fire situation and improve the accuracy of monitoring.

[0041] In some embodiments, the control system for early warning and fire extinguishing further includes a switch 80, which is electrically connected to the sensor device 20, the start-stop device 30, the control device 40, the electric ball valve 50 and the temperature measuring host 70, and the switch 80 is used to realize information communication between the sensor device 20, the start-stop device 30, the control device 40, the electric ball valve 50 and the temperature measuring host 70. Specifically, the temperature measuring host 70 is a mine intrinsically safe distributed optical fiber temperature measuring host 70.

[0042] In some embodiments, a first switch 81, a second switch 82 and a third switch 83 are included. The first switch 81 is a mining intrinsically safe gigabit network switch, the second switch 82 is a network switch (RS485), and the third switch 83 is an intrinsically safe switch.

[0043] In some embodiments, after the sensor device 20 obtains the fire information, the fire information is automatically sent to the temperature measuring host 70, and then the temperature measuring host 70 directly sends a power-off command to the starter through the network switch 80 to control the conveying device 10 to stop.

[0044] In some embodiments, the control device 40 includes an industrial computer 41, a display 42, and an audible and visual alarm 43. The industrial computer 41 is electrically connected to the switch 80, the display 42, and the audible and visual alarm 43. The industrial computer 41 is built with an information processing chip, and the information processing chip is used to process the communication information of the switch 80 and transmit the information to the display 42 and the audible and visual alarm 43 to achieve human-computer interaction. Specifically, the display 42 can display digital information such as pictures, charts, temperature, carbon monoxide concentration, smoke concentration, etc. The audible and visual alarm 43 can emit an alarm or an alarm signal light, which has made it easier for the operator to identify the fire through multiple human-computer interactions, thereby preventing the expansion or spread of the fire.

[0045] In some embodiments, the control system for early warning and fire extinguishing also includes a power supply 90. Multiple power supplies 90 can be set to supply power to the switch 80, the temperature sensing host, the PLC, and the electric ball valve 50 respectively to ensure normal power supply.

[0046] In some embodiments, an audible and visual alarm 43 is also provided near the conveying device 10 to generate an alarm in the well, so that workers in the well can evacuate quickly or deal with the fire.

Of course, part of the switch 80, the power supply 90 and part of the lines can also be arranged in the mine.

[0048] In the present application, when a fire occurs in the conveying device 10, the sensor device 20 can transmit the fire information to the control device 40, and the control device 40 sends a command to the start-stop device 32 to control the start-stop device 32 to stop the conveying device 10, thereby reducing the fire expansion or spread caused by the jamming, friction, deviation, coal piling, etc. of the conveying device 10 during transportation, and can even stop the conveying device 10 when the fire just occurs or when there is a tendency for the fire to occur, so that the fire is automatically extinguished or the fire is avoided. In addition, by setting up PLC, temperature sensing host, electric ball valve 50 and other devices to cooperate with the conveying device 10, sensor device 20, start-stop device 30 and control device 40, rapid response and processing of the fire can be achieved, the impact of the fire can be reduced, and property losses can be reduced.
