Description

Technical Field

[0001] This utility model relates to the field of mine fire monitoring technology, specifically to a mine fire detection and early warning device with remote Internet monitoring. Background Technology

[0002] A mine shaft is a shaft or tunnel excavated to access underground mineral deposits. It is the collective term for the shafts, chambers, equipment, and surface structures that make up a complete underground mining production system. Its main function is to extract underground natural resources such as ores, gems, or coal, and it is widely used in the mining industry, especially coal mining. Mine fires are mainly divided into internal and external fires. Internal fires are caused by spontaneous combustion of coal and account for more than 90% of all mine fires. They are commonly found in goaf areas, coal roadway roofs, and other locations, and are characterized by their high concealment and long duration. External fires are caused by external heat sources, such as open flames or electric sparks, and often occur in areas where electromechanical equipment is concentrated, such as working faces and shafts. Therefore, monitoring mine fires is particularly important.

[0003] Currently, mine fire detection and early warning devices with remote internet monitoring typically use sensors on detection probes to detect the concentration of gases in the air and transmit the detection data over a network via a wireless communication module, enabling real-time remote monitoring and early warning. However, in actual use, existing devices often have limitations. Because the locations of the detection probes deployed in the mine are usually fixed, there may be dead zones in the flow of gases dispersed after combustion when they pass through the detection probes, making it difficult to promptly absorb and detect the gases, thus affecting the effectiveness of the device. Utility Model Content

[0004] The purpose of this invention is to provide a mine fire detection and early warning device for remote internet monitoring. By setting up a rotating rod, guide frame, handle, and drive shaft, and with the cooperation of the drive assembly, the guide frame can drive the rotating rod to rotate back and forth. Then, the rotating rod can drive the movable cover at its bottom end to slide back and forth on the bottom side of the fixed cover. This allows the fixed cover to cause the air intake pipe to deflect significantly to the left and right. Furthermore, with the cooperation of the first gear, second gear, and driven shaft, the driven shaft can simultaneously control the fan blades to rotate, generating suction below the fan blades to draw air towards the detection head body. This allows for the rapid introduction of surrounding air into the connecting pipe over a large area, greatly reducing the dead zone of air intake and accelerating the air intake rate. The device has good performance and solves the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine fire detection and early warning device with remote internet monitoring, comprising:

[0010] Preferably, the top center of the fixed cover is rotatably connected to a driven shaft via a rotating shaft. The top of the driven shaft is provided with a fan blade inside the connecting pipe. The fan blade is located below the air outlet. The bottom of the driven shaft is provided with a second gear inside the fixed cover. The second gear is located inside the U-shaped support frame.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By setting up structures such as a rotating rod, guide frame, rotating handle, and drive shaft, and with the cooperation of the drive assembly, the guide frame can drive the rotating rod to rotate back and forth left and right. Then, the rotating rod can drive the movable cover at the bottom end to slide back and forth left and right on the bottom side of the fixed cover.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-5 The remote internet-monitored mine fire detection and early warning device shown includes:

[0028] The frame 1 has an electric push rod 2 fixed to its inner bottom end. The top of the electric push rod 2 is provided with a top seat 3 near the top of the frame 1. A protective frame 5 is connected to the top side of the top seat 3. Based on this, the top seat 3 can be driven to rise and fall by the electric push rod 2, so that the top seat 3 drives the detection head body 6 to rise and fall through the protective frame 5, thereby adjusting the height position of the air inlet pipe 11.

[0029] An alarm 4 is installed on the top side of the top seat 3.

[0030] The inner top of the protective frame 5 is provided with a detection head body 6, the bottom of the detection head body 6 is connected to a connecting pipe 7, and the detection head body 6 is provided with a circuit board 33. The circuit board 33 is provided with a wireless communication module 34. The side wall of the connecting pipe 7 is provided with an air outlet 8. The bottom of the connecting pipe 7 is fixed with a fixed cover 9. The bottom side of the fixed cover 9 is slidably connected with a movable cover 10. One end of the movable cover 10 is provided with an air inlet pipe 11. Multiple through holes 25 are provided between the fixed cover 9 and the connecting pipe 7.

[0031] In use, air from the mine can enter the movable cover 10 and the fixed cover 9 through the air inlet pipe 11, and then flow into the connecting pipe 7 through the through hole 25. Then, under the action of multiple detection sensors at the bottom of the detection head body 6, the concentration of gas in the air can be detected. The sensors may include carbon monoxide sensors, methane gas sensors, hydrogen sensors, and temperature sensors, etc., so as to effectively detect whether a fire has occurred. The detection data can be transmitted to the network by the wireless communication module 34 to realize real-time remote monitoring, so as to promptly warn the staff when a fire occurs, and at the same time control the alarm 4 to issue an alarm to remind the workers on site.

[0032] The fixed cover 9 has an annular groove on its bottom side, and the movable cover 10 has a sliding ring on its top side that matches the annular groove. Based on this, the movable cover 10 can rotate on the bottom side of the fixed cover 9 through the sliding engagement of the sliding ring and the annular groove.

[0033] A U-shaped support frame 12 is fixed in the middle of the top side inside the fixed cover 9. A rotating rod 13 is rotatably connected to the bottom side of the U-shaped support frame 12. The bottom end of the rotating rod 13 is fixedly connected to the movable cover 10, and a guide frame 17 is fixed to the top end of the rotating rod 13. A drive shaft 14 is rotatably connected to one side of the top end inside the guide frame 17. A rotating handle 15 is fixed to the bottom end of the drive shaft 14 near the top of the guide frame 17. A guide post 16 is connected to one end of the rotating handle 15, and the guide post 16 is slidably fitted inside the guide frame 17. A drive assembly is connected to the top end of the drive shaft 14.

[0034] The drive assembly includes a motor 22 fixed on the top of the fixed cover 9 near the connecting pipe 7. One end of the motor 22 extending into the inside of the fixed cover 9 and the top of the drive shaft 14 are both fixed with synchronous pulleys 23. A synchronous belt 24 is provided between the two synchronous pulleys 23.

[0035] A driven shaft 20 is rotatably connected to the top center of the fixed cover 9 via a rotating shaft. The top of the driven shaft 20 is located inside the connecting pipe 7 and has a fan blade 21. The fan blade 21 is located below the air outlet 8. The bottom of the driven shaft 20 is located inside the fixed cover 9 and has a second gear 19. The second gear 19 is located inside the U-shaped support frame 12. One end of the drive shaft 14 is located between the synchronous wheel 23 and the handle 15 and has a first gear 18 that meshes with the second gear 19.

[0036] By starting the motor 22, the motor 22 can drive the two synchronous pulleys 23 to rotate simultaneously via the synchronous belt 24. Then the synchronous pulleys 23 drive the drive shaft 14 to rotate. The drive shaft 14 can drive the second gear 19 to rotate via the first gear 18, so that the second gear 19 drives the driven shaft 20 to rotate faster. Then the driven shaft 20 can drive the fan blade 21 to rotate, so that the fan blade 21 generates suction to draw air to the detection head body 6.

[0037] Meanwhile, the drive shaft 14 can drive the handle 15 to make a circular motion, so that the handle 15 drives the guide post 16 to slide back and forth in the guide frame 17. This allows the guide frame 17 to drive the rotating rod 13 to rotate back and forth. Then, the rotating rod 13 can drive the movable cover 10 at the bottom end to slide back and forth on the bottom side of the fixed cover 9. This allows the fixed cover 9 to drive the intake pipe 11 to deflect significantly to the left and right, thereby rapidly introducing the surrounding air into the connecting pipe 7 over a large area. This greatly reduces the dead angle of air intake and speeds up the air intake rate, resulting in better performance.

[0038] Each of the four legs of the support frame 1 is provided with a sliding cavity 26, and the bottom of the support frame 1 is rotatably connected to a support seat 29 facing the sliding cavity 26 on all four sides. A T-shaped slider 27 is slidably connected inside the sliding cavity 26. A connecting arm 28 is rotatably connected between the T-shaped slider 27 and the support seat 29. Both ends of the legs of the support frame 1 are provided with threaded grooves 31, and a fixing knob 30 is screwed into one of the threaded grooves 31. The side wall of the T-shaped slider 27 is provided with a positioning hole 32 facing the fixing knob 30.

[0039] The support base 29 has a hollow cavity on its side wall and a connecting hole at its end. This connecting hole allows for easy securing of the support base 29 to the ground using screws.

[0040] By setting up the protective frame 5, the air detection structure below can be protected. After the upright frame 1 is placed on the ground, the four sets of support seats 29 can be pulled in sequence, so that the support seats 29 drive the T-shaped slider 27 to slide in the sliding cavity 26 through the connecting arm 28. After the support seats 29 unfold and contact the ground, the fixing knob 30 can be screwed on in the fixing knob 30 under the support leg, so that the fixing knob 30 is tightened in the positioning hole 32, and the T-shaped slider 27 can be locked on the upright frame 1. This further forms a support frame at the bottom of the device to effectively support it on the ground, which greatly improves the stability of the device when used in the mine. Conversely, multiple sets of support seats 29 can be folded up and fixed in sequence to quickly store the device, making it convenient to carry and move, which greatly improves the use effect of the device.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
