[0002] Coal mines are areas where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. Among them, underground mining accounts for a higher proportion of coal mining. When underground mining is carried out, tunnels are excavated underground. In order to increase the safety of underground production and construction, support frames are used to support the coal mine tunnels. At the same time, gas monitoring instruments are installed on the support structure of the coal mine tunnels to detect the air quality underground and promptly remind construction workers to evacuate safely when the gas concentration is too high.

[0003] Chinese Patent Publication CN218729349U discloses a detection device for safe production in coal mines. Through the cooperation of a handle, worm gear and worm wheel, a threaded rod can be driven to rotate. The threaded rod can drive the pin to disengage from the slot through the threaded sleeve and the cross plate, thereby removing the connecting plate and then removing the infrared grating alarm. Disassembly can be completed without special tools, making it more convenient for workers to disassemble.

[0004] The existing coal mine underground safety production detection devices described above, while capable of detecting and alarming the underground environment using gas monitors and other detection equipment, do not assist construction workers in safely evacuating dangerous roadways. This makes it easy for workers to inhale harmful gases during evacuation, thus affecting the protective effect of the coal mine underground safety production detection devices. Therefore, this paper proposes a detection device for coal mine underground safety production. Utility Model Content

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0016] Please see Figures 1-4 This utility model embodiment provides a detection device for safe production in coal mines, including two support frames 1, and a flipping mechanism 2 is provided on the opposite sides of the two support frames 1. The flipping mechanism 2 includes two fixed plates 201. The upper surfaces of the two fixed plates 201 are fixedly connected to the inner top walls of the two support frames 1 respectively. The two fixed plates 201 are hinged together on opposite sides. Several emergency packs 203 are set above the flipping plate 202. Protective shells 204 are fixedly connected to the opposite sides of the two fixed plates 201. Electric push rods 205 are fixedly connected to the inner top walls of the two protective shells 204. A gas monitor 209 is fixedly connected to the inner wall of one of the support frames 1. The two electric push rods 205 are electrically connected to the gas monitor 209 through wires. The gas monitor 209 can detect the gas concentration in the air of the underground roadway of the coal mine and issue an alarm in time to ensure the normal operation of the safety production monitoring work in the underground coal mine.

[0017] Please refer to this carefully. Figure 3 The telescopic ends of the two electric push rods 205 are fixedly connected to conical plates 206. The outer surfaces of the two conical plates 206 are fixedly connected to positioning blocks 207. One side of each positioning block 207 penetrates the fixing plate 201 and contacts the bottom surface of the flip plate 202. The inner top walls of the two protective shells 204 are fixedly connected to several limiting plates 210. Each limiting plate 210 is slidably connected to the conical plate 206. The limiting plates 210 can increase the stability of the conical plate 206 sliding up and down and prevent the conical plate 206 from becoming loose.

[0018] Please refer to this carefully. Figure 3 Each of the two positioning blocks 207 has a return spring 208 fixedly connected to one side. The other end of each return spring 208 is fixedly connected to the inner wall of the protective shell 204. Each return spring 208 has a sliding rod 211 inside. One end of each sliding rod 211 is fixedly connected to one side of the positioning block 207, and the other end of each sliding rod 211 extends through to the outside of the protective shell 204. The sliding rod 211 can improve the stability of the movement of the positioning block 207 and prevent the positioning block 207 from getting stuck.

[0019] Please refer to this carefully. Figure 2 and Figure 4Two support frames 1 are provided with auxiliary components 3 on opposite sides. The auxiliary components 3 include a protective cover 301. The bottom surface of the protective cover 301 is hinged to the upper surface of the flip plate 202. Three elastic ropes 302 are fixedly connected to the upper surface of the protective cover 301. The other ends of the three elastic ropes 302 are fixedly connected to a connecting plate 303. The two sides of the connecting plate 303 are fixedly connected to the opposite sides of the two support frames 1. Several folded ropes 304 are fixedly connected to the upper surface of the flip plate 202. A Velcro 305 is fixedly connected to the outer surface of each folded rope 304. The bottom surface of each emergency pack 203 is connected to the Velcro 305. The adhesive, through the protective cover 301 and the flip plate 202, can protect the emergency pack 203 from dust and impurities. When the flip plate 202 is flipped, since the hinge position of the protective cover 301 and the flip plate 202 is on one side, it will not affect the smooth flipping of the flip plate 202. At the same time, the elastic rope 302 and the connecting plate 303 limit the protective cover 301, which can ensure that the emergency pack 203 falls out smoothly. Then, through the folding rope 304 and the Velcro 305, the emergency pack 203 can only be suspended in mid-air and will not fall to the ground, making it convenient for construction personnel to quickly retrieve the emergency pack 203 during evacuation.

[0020] Please refer to this carefully. Figure 2 Each folding rope 304 has a limiting cover 306 on its outer surface. The bottom surface of each limiting cover 306 is fixedly connected to the upper surface of the flip plate 202. Each emergency pack 203 is placed inside the limiting cover 306. The limiting cover 306 can restrict the position of the emergency pack 203 on the flip plate 202 and increase the stability of the emergency pack 203.

[0021] In use, this invention works as follows: First, the electric push rod 205 and the gas monitor 209 are connected to an external power source and controller. Then, the protective cover 301, in conjunction with the flip plate 202, protects the emergency pack 203 from dust and impurities. When the gas monitor 209 detects excessively high gas concentrations that could harm workers and issues an alarm, the electric push rod 205, connected by wires, moves in response to the alarm. The power provided by the electric push rod 205, along with the limiting plate 210, pushes the conical plate 206 downwards. As the conical plate 206 moves downwards, its inclined surface forces the positioning block 207 to retract into the protective shell 204. This, in conjunction with the sliding rod 211, causes the return spring 208 to contract and accumulate elastic force, providing power for the subsequent repositioning of the positioning block 207. Once the positioning block 207 is retracted into the protective shell 204, one side of the flip plate 202 loses its limiting position. The flip plate 202, with its hinged connection to the fixed plate 201 on only one side, combined with gravity, allows for a smooth transition. The device allows the flipping plate 202 to flip downwards along the hinge point on one side of the fixed plate 201. After the flipping plate 202 flips, since the hinge point between the protective cover 301 and the flipping plate 202 is on the same side, it will not affect the smooth flipping of the flipping plate 202. At the same time, the elastic rope 302 and the connecting plate 303 limit the protective cover 301, ensuring that the emergency pack 203 falls outwards smoothly and preventing the protective cover 301 from affecting the fall of the emergency pack 203. Then, the folding rope 304 and Velcro 305 ensure that the emergency pack 203 is suspended in mid-air and will not fall to the ground, making it convenient for construction personnel to quickly retrieve the emergency pack 203 during evacuation. The emergency oxygen tank, lighting, and face mask in the emergency pack 203 can be used to assist in the evacuation. This allows the underground safety production detection device in the coal mine to assist construction personnel in evacuating dangerous underground roadways more safely, reducing the amount of harmful gases inhaled by construction personnel during the evacuation process and increasing the protective effect of the underground safety production detection device in the coal mine.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
