Description

Technical Field

[0001] The utility model relates to the field of spontaneous combustion warning of coal piles, in particular to a warning device for the concentration index of coal spontaneous combustion gas. Background Technique

[0002] With the extensive utilization of coal resources, the problem of spontaneous combustion of coal piles has become increasingly prominent. During the storage process of coal piles, various combustible gases will be generated due to microbial activities and chemical reactions. When the concentration is too high, the combustible gases may cause the coal piles to spontaneously combust. The spontaneous combustion of coal piles not only causes waste of resources, but also may trigger fires, threatening personnel and property.

[0003] For the detection of the concentration of spontaneous combustion gas in the existing coal piles, generally a carbon monoxide sensor, a methane sensor, etc. are set above the coal piles to detect the concentration of combustible gases escaping from the coal piles. When the concentration of combustible gases exceeds the threshold, an alarm is issued to remind the staff to take measures. However, the existing warning devices for coal pile spontaneous combustion mainly focus on the monitoring of gas concentration. After the tendency of spontaneous combustion is found, the temperature reduction treatment usually depends on manual intervention, with low response efficiency, which may make the spontaneous combustion of coal piles more dangerous.

[0004] Therefore, a warning device for the concentration index of coal spontaneous combustion gas is now developed, which can automatically spray water to cool the coal pile when the concentration of combustible gas in the coal pile exceeds the standard or the temperature of the coal pile is too high, so as to avoid the spontaneous combustion of the coal pile. Content of the Utility Model

[0005] In order to overcome the shortcomings that the existing warning devices for coal pile spontaneous combustion mainly focus on the monitoring of gas concentration, and after the tendency of spontaneous combustion is found, the temperature reduction treatment usually depends on manual intervention, with low response efficiency, which may make the spontaneous combustion of coal piles more dangerous, the utility model provides a warning device for the concentration index of coal spontaneous combustion gas, which can automatically spray water to cool the coal pile when the concentration of combustible gas in the coal pile exceeds the standard or the temperature of the coal pile is too high, so as to avoid the spontaneous combustion of the coal pile.

[0006] The technical solution is: a warning device for the concentration index of coal spontaneous combustion gas, including a fixed rod, sensors, a spacer ring, a water pipe, an interface, a monitoring component, an alarm component and a water spraying component.

[0008] Further, a flange is arranged on the interface.

Detailed Embodiments

[0016] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0017] A coal spontaneous combustion gas concentration index warning device, as Figure 1 and Figure 2 shown, includes a fixing rod 1, a sensor 2, a spacer ring 3, a water pipe 4, an interface 5, a monitoring component, an alarm component, and a water spraying component. Three sensors 2 are connected to the fixing rod 1. The lower part of the fixing rod 1 is in a pointed shape for easy insertion into the coal pile. A spacer ring 3 is provided on the upper part of the fixing rod 1. The water pipe 4 is connected to the upper part of the spacer ring 3. The interface 5 is connected to the left side of the water pipe 4, and a flange is provided on the interface 5 for easy docking. The monitoring component is provided on the water pipe 4, the alarm component is provided on the water pipe 4, and the water spraying component is also provided on the water pipe 4.

[0018] AsFigure 1 As shown in the figure, the monitoring component includes a fixing bracket 6, a concentration monitor 7, a data line 8 and a controller 9. Three fixing brackets 6 are connected to the upper side of the water pipe 4. A concentration monitor 7 is connected to each fixing bracket 6. A data line 8 is connected between the concentration monitors 7. A controller 9 is connected to the upper part of the water pipe 4. The controller 9 is connected to the concentration monitor 7.

[0019] As Figure 1 and Figure 2 shown in the figure, the alarm component includes a speaker 10 and an alarm lamp 11. A speaker 10 is connected to the upper part of the water pipe 4. Alarm lamps 11 are connected to both the left and right sides of the speaker 10.

[0020] As Figure 1 and Figure 2 shown in the figure, the water spraying component includes a fixed shell 12, a turbine 13, a rotating bracket 14 and a spray pipe 15. A fixed shell 12 is connected to the upper side of the water pipe 4. A turbine 13 is rotatably connected inside the fixed shell 12. A rotating bracket 14 is connected to the upper side of the turbine 13. Thirty-six spray pipes 15 are provided on the rotating bracket 14.

[0021] When using the present utility model, first insert the fixed rod 1 into the coal pile to be detected, use the sensor 2 to monitor the temperature inside the coal pile, then dock the water pipe 4 with the water inlet pipe through the interface 5. The spacer ring 3 can separate the fixed rod 1 and the water pipe 4. The combustible gas in the coal pile will escape from the coal pile. The concentration detector can detect the concentration of the escaped combustible gas. Due to the different densities of the combustible gases, they will be stratified on the surface of the coal pile. The upper and lower different concentration sensors 2 can respectively monitor the concentrations of different types of combustible gases, and transmit the monitored results to the controller 9 through the data line 8. When the controller 9 detects that the concentration of the combustible gas exceeds the standard or detects that the temperature inside the coal pile is abnormal, the controller 9 controls the speaker 10 to give an audible alarm and controls the alarm lamp to flash, and at the same time controls the water pipe 4 to let water in, so that the water flows to the upper part of the water pipe 4, causing the turbine 13 in the fixed shell 12 to rotate, causing the rotating bracket 14 to rotate, causing the spray pipe 15 to rotate, and making the water evenly sprayed on the coal pile to cool the coal pile, thus playing the role of automatically spraying water to cool the coal pile when the concentration of the combustible gas in the coal pile exceeds the standard or the temperature of the coal pile is too high, avoiding the spontaneous combustion of the coal pile.
