Technical Field

[0001] The utility model relates to the technical field of mine shaft alarm and fire extinguishing, in particular to a mine shaft alarm and fire extinguishing control device. Background Technique

[0002] A "shaft" usually refers to a structure built on the ground to protect the wellhead, commonly found in underground projects such as mines, oil wells, and water wells. The shaft helps to ensure the safety of the wellhead, provides a passage to enter and leave the wellhead, and can also support the soil and rock around the wellhead.

[0003] In the existing technology, in order to reduce the probability of fire in the mine, alarm and fire extinguishing devices are usually arranged at the shaft. The temperature is detected by a temperature measurement optical cable installed on one side of the conveyor belt, and the detection result is transmitted to the temperature measurement host at the terminal. When the temperature is too high, the spray device is set to spray water on the conveyor belt to cool it down. During use, as a necessary detection line, the temperature measurement optical cable is exposed to the air. The air in the mine not only has a high dust content, but also a large amount of water mist adheres to the surface of the temperature measurement optical cable after single spray cooling, affecting the use of the temperature measurement optical cable.

The brush bristles 403 are fixed outside the cleaning roller 402, and the brush bristles 403 are in contact with the temperature-measuring optical cable 3. On one side of both the friction wheel 401 and the cleaning roller 402, a synchronous pulley 404 is installed. The two groups of synchronous pulleys 404 can rotate simultaneously through a synchronous belt 405. The outside of the synchronous pulley 404 is meshed and connected with the synchronous belt 405 through tooth grooves.

[0023] As Figure 1 and Figure 3 shown, outside the conveyor assembly 2, multiple groups of spraying assemblies 6 are provided. The spraying assembly 6 includes a support frame 601 fixed inside the mine 1. The support frame 601 can support the diverging pipe 602. At the top of the support frame 601, a diverging pipe 602 is installed. The diverging pipe 602 can divide the clear water. At the bottom end of the diverging pipe 602, a plurality of nozzles 603 are installed at equal intervals. The nozzles 603 can atomize and spray the clear water to cool the conveyor belt 202.

[0024] As Figure 1 and Figure 3As shown, one end of the shunt pipe 602 is fixed with a main water pipe 7. The main water pipe 7 can transport cooling water, and the diameter of the main water pipe 7 is larger than that of the shunt pipe 602.

[0025] As Figure 1 shown, on one side of the conveying assembly 2 in the mine 1, an electric control assembly 5 is installed. The electric control assembly 5 includes a power supply box 501 and an electric ball valve 502.

[0026] As Figure 1 shown, the temperature measurement optical cable 3 is connected to the power supply box 501 through a line, and a temperature measurement host for detection is connected to the terminal of the temperature measurement optical cable 3. The power supply box 501 can supply power to the temperature measurement optical cable 3, and the detection signal of the temperature measurement optical cable 3 is transmitted to the temperature measurement host.

[0027] As Figure 1 shown, the electric ball valve 502 is connected to the main water pipe 7 through a pipeline, and the electric ball valve 502 is electrically connected to the power supply box 501. The model of the electric ball valve 502 is DFH20 / 7, and the on-off of the main water pipe 7 is controlled by the electric ball valve 502.

[0028] As Figure 1 shown, a support rod 8 is installed above the conveying assembly 2 in the mine 1. The bottom end of the support rod 8 is fixed with a smoke sensor 9, and the smoke sensor 9 is installed out of alignment with the spray assembly 6. The support rod 8 can support the smoke sensor 9. The model of the smoke sensor 9 is GQQ5, and the smoke in the mine 1 is detected by the smoke sensor 9.

[0029] The working principle of this device: When this device is specifically used, the staff installs multiple groups of electric control assemblies 5, spray assemblies 6, support rods 8 and smoke sensors 9 in the mine 1 according to the protection requirements. Then, the temperature measurement optical cable 3 is installed in the frame 201 of the conveying assembly 2 and connected to the power supply box 501 in the electric control assembly 5, and the terminal of the temperature measurement optical cable 3 is connected to the temperature measurement host. During the process of the conveyor belt 202 transporting coal, the temperature at the conveyor belt 202 is detected through the temperature measurement optical cable 3, and the detection result is fed back to the terminal device. When the temperature exceeds the limit, the electric ball valve 502 is opened by setting corresponding programs. At this time, the clear water in the main water pipe 7 is shunted through the shunt pipe 602 in the spray device and finally sprayed onto the conveyor belt 202 through the nozzle 603 to cool it by spraying water and prevent potential fire hazards.

[0030] During use, the friction wheel 401 contacts the conveyor belt 202 and is driven to rotate by the frictional force. During the rotation process, one of the synchronous wheels 404 is driven to rotate, and then the other synchronous wheel 404 is driven to rotate through the synchronous belt 405. When the other side synchronous wheel 404 rotates, the cleaning roller 402 rotates. During the rotation of the cleaning roller 402, the brush bristles 403 are driven to contact the temperature measurement optical cable 3. Through the brush bristles 403, not only can dust in the air be prevented from adhering to the temperature measurement optical cable 3, but also the surface of the temperature measurement optical cable 3 can be cleaned. At the same time, after single-time spray cooling, the water mist adhering to the temperature measurement optical cable 3 can be quickly cleaned, ensuring the normal use of the temperature measurement optical cable 3, improving the temperature measurement accuracy. At the same time, the support rod 8 supports the smoke sensor 9, and the smoke sensor 9 detects the smoke in the mine 1.
