DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0036] like Fig.14 As shown, a geological anomaly detection device for a coal mine working face in one embodiment of the present invention includes a first geological anomaly detector and a second geological anomaly detector. The first geological anomaly detector plays a role in assisting the detector. When entering the working face from the wellhead for the first time, it can gradually enter and detect parameters such as CH4, CO2, CO, H2S, and temperature in the working face. After the first geological anomaly detector performs a preliminary detection to ensure that there is no danger in the entered area, the detector enters for a more detailed detection, which can avoid dangerous situations caused by the blind entry of the detector.

[0037] The second geological anomaly detector is set in the working face after the preliminary exploration is completed. The second geological anomaly detector can reciprocate to detect parameters such as gas, air volume, and temperature in the working face. In addition, the second geological anomaly detector can ensure the uniformity of detection standards during the inspection process, and the credibility and stability of the detection data can be guaranteed, greatly improving the detection efficiency. In non-essential situations, the investigators can stay out of the way to avoid potential safety hazards during the exploration process. Compared with manual exploration, the second geological anomaly detector is more efficient.

[0038] like Figure 1 As shown, the second geological anomaly detector includes a slide rail 1 and a slider 2, wherein the slide rail 1 is fixedly connected to the top wall of the working surface, and the slider 2 slides along the direction in which the slide rail 1 is set. As the length of the working surface becomes longer, an additional slide rail 1 can be provided at one end of the slide rail 1, thereby increasing the range of motion of the slider 2 and expanding the detection range of the second geological anomaly detector.

[0039] like Figure 1 to Figure 3 As shown, the second geological anomaly detector further includes a liquid cooling mechanism 4 and an anomaly detection mechanism 15. The liquid cooling mechanism 4 is used to provide heat dissipation for the anomaly detection mechanism 15 to prevent the anomaly detection mechanism 15 from causing high temperature under long-term working conditions. A first motor 3 is installed between the liquid cooling mechanism 4 and the slider 2. The first motor 3 can realize the rotation of the liquid cooling mechanism 4, thereby realizing the U-turn operation of the second geological anomaly detector.

[0040] The liquid cooling mechanism 4 includes a first water tank 5, which is hollow and stores cooling liquid. The cooling liquid is generally water or other liquid with flame retardancy. The first water tank 5 is provided with a mounting groove 501 matching the abnormality detection mechanism 15. A part of the abnormality detection mechanism 15 is mounted in the mounting groove 501. The side walls of the mounting groove 501 are all made of metal with strong heat exchange capacity, such as copper, silver, aluminum, etc. In general, the part of the abnormality detection mechanism 15 that generates severe heat is located in the mounting groove 501. The part of the abnormality detection mechanism 15 that generates severe heat can exchange heat with the cooling liquid in the first water tank 5, thereby improving the heat dissipation performance of the abnormality detection mechanism 15 and extending the service life of the abnormality detection mechanism 15.

[0041] like Figure 1 to Figure 3As shown, a pair of first protective shells 6 are fixedly connected to the first water tank 5, and the first protective shells 6 are respectively located on both sides of the abnormality detection mechanism 15. An air flow channel is formed between the first water tank 5 and the first protective shell 6. A mounting hole 602 is provided on the first protective shell 6, and a heat dissipation fan 7 is installed in the mounting hole 602. A dustproof net 601 is provided at one end of the heat dissipation fan 7 close to the abnormality detection mechanism 15, and a heat dissipation fan 7 matching the dustproof net 601 is installed on the first protective shell 6. An opening is provided at one end of the first protective shell 6 away from the heat dissipation fan 7, and a dustproof net 601 is installed at the opening of the first protective shell 6. The heat dissipation fan 7 can allow air to enter from the dustproof net 601 and be discharged by the heat dissipation fan 7. The air passes through the first water tank 5 and exchanges heat with the surface of the first water tank 5 to achieve cooling of the cooling liquid in the first water tank 5. The temperature of the cooling liquid close to the abnormality detection mechanism 15 is higher. The heat dissipation fan 7 is arranged at one end close to the abnormality detection mechanism 15, which can increase the cooling speed of the cooling liquid in the first water tank 5.

[0042] like Figure 1 to Figure 3 As shown, the abnormality detection mechanism 15 includes an abnormality detection host 16, which is installed in the installation groove 501, and one end of the abnormality detection host 16 is located outside the installation groove 501. The end of the abnormality detection host 16 located outside the installation groove 501 is installed with a first set detector 17, and the first set detector 17 can realize external detection of the geology of the coal mine working face through vision. In the process of moving in the direction set by the slide rail 1, it can identify safety hazards, illegal intrusion identification, gas identification, safety hazard identification, dangerous behavior identification, etc. A number of detectors are integrated on the first set detector 17, and the first set detector 17 can be set according to actual needs.

[0043] like Figure 1 to Figure 3 As shown, the first water tank 5 is equipped with an alarm 18 and an ultrasonic detector 19 that match the abnormality detection host 16. The ultrasonic detector 19 detects the situation in the coal seam by ultrasonic wave, and moves with the abnormality detection mechanism 15 to perform multi-point detection. The alarm 18 can sound an alarm in case of emergency, providing orderly evacuation for the underground workers.

[0044] like Figure 1 to Figure 6As shown, the coal mine working face needs to be sprayed with water to improve the environmental quality of the coal mine working face, reduce the risk of dust inhalation by underground workers, and protect the health of underground workers. The existing spray device is generally set in the working face to improve the environmental quality of the underground workers in the coal mine. It is difficult to achieve different spraying and humidification according to the specific humidity of the working face. In order to solve the above problems, the fan blades of the heat dissipation fan 7 are hollow fan blades 8, and a rotating shaft 9 is fixedly connected to the central axis of the hollow fan blade 8. A first connecting pipe 10 is installed between the rotating shaft 9 and the first water tank 5. The cooling liquid in the first water tank 5 is pumped into the hollow fan blade 8 through the first connecting pipe 10. A plurality of evenly distributed first nozzles 11 are fixedly connected to the hollow fan blade 8. By opening the first nozzle 11, the liquid in the hollow fan blade 8 can be discharged. The first nozzle 11 can spray water mist of different particle sizes and densities in accordance with the results detected by the first collective detector 17, and the wetting of the coal mine working face can be achieved in a targeted manner according to the actual situation.

[0045] like Figure 1 to Figure 6 As shown, a micro water pump 1001 is installed at one end of the first connecting pipe 10 away from the rotating shaft 9, and the micro water pump 1001 provides power for the liquid in the first water tank 5 to enter the hollow fan blade 8. Among them, an air intake valve (not shown in the figure) is provided on the first water tank 5, and the air intake valve operates during the operation of the micro water pump 1001. That is, the liquid level in the first water tank 5 drops, and the air intake valve can avoid the negative pressure in the first water tank 5. In addition, after the liquid level in the first water tank 5 drops, the heat dissipation performance of the abnormality detection mechanism 15 will also deteriorate. Through the cooperation of the micro water pump 1001 and the air intake valve, cold air can be filled into the first water tank 5 and discharged, as a substitute for cooling liquid heat exchange, to ensure that the temperature of the abnormality detection mechanism 15 during use will not be too high.

[0046] like Figure 1 to Figure 6 As shown, two symmetrically arranged rotating shafts 701 are fixedly connected to the heat dissipation fan 7, and the rotating shafts 701 are rotatably connected to the side walls of the dustproof net 601. One of the rotating shafts 701 is located outside the first protective shell 6, and the first protective shell 6 is fixedly connected to a second motor 12 for driving the rotating shaft 701. That is, the heat dissipation fan 7 can rotate vertically in the dustproof net 601, and through the vertical rotation, it can be ensured that the water sprayed by the heat dissipation fan 7 can cover the side walls and top wall of the working surface, so as to realize the wetting of the coal mine working surface in all directions.

[0047] The wetting of the coal mine working face during the exploration process can greatly save water resources and avoid the waste of water resources. In addition, there is no need to set up additional pipelines. The wetting compensation of the coal mine working face can be carried out in the place where the second geological anomaly detector can reach.

[0048] There is also the possibility of gas outbursts in coal mine working faces, that is, a large amount of gas suddenly gushes out from coal cracks in a short period of time. In this case, the underground workers need to evacuate in time. If they are not evacuated in time, inhaling too much gas will affect the health of the underground workers. In order to provide safety guarantees for the evacuation of underground workers, such as Figures 1 to 9 As shown, the second geological anomaly detector is equipped with a second connecting pipe 13, one end of which is connected to the first water tank 5, and a plurality of evenly distributed second nozzles 14 are fixedly connected to the second connecting pipe 13. The second nozzle 14 can spray the cooling liquid in the first water tank 5 in the form of water mist, and the water mist forms a gas barrier. The water mist particles collide and adsorb with the gas molecules, so that the gas molecules are carried by the water mist particles and settle down, so as to slow down the spread of gas and facilitate the evacuation of underground workers. The evaporation of water mist will also absorb heat, reduce the ambient temperature, and reduce the possibility of gas explosion.

[0049] like Figures 1 to 9 As shown, the second nozzles 14 have three groups, and the three groups of second nozzles 14 correspond to three different directions respectively, and can spray separately according to the location of gas outflow to avoid wasting water resources. In the case of excessive gas concentration, all the second nozzles 14 in multiple different directions can work, so that the water mist quickly covers the gas outflow area. It is even possible to set up a water mist barrier in advance on the evacuation channel of the underground mine workers to isolate the gas in the outflow area as much as possible. After the underground mine workers pass through the water mist barrier, the gas concentration is reduced, avoiding the situation where the underground mine workers inhale too much gas and affect their health.

[0050] In the actual work process, if there is a gas outflow, someone needs to turn off the power supply in the gas outflow area to avoid sparks from electricity causing gas explosion. The underground workers who perform this work may miss the best evacuation time and inhale too much gas, which will affect their health. In order to solve the above problems, such as Figures 1 to 8 As shown, the second geological anomaly detector is equipped with a first oxygen supply mechanism 20, in which compressed air is stored. The compressed air in the first oxygen supply mechanism 20 can provide safety protection for underground mine workers who miss the best evacuation time.

[0051] Specifically, Figures 1 to 8As shown, the first oxygen supply mechanism 20 includes a second gas tank 21, and compressed air is stored in the second gas tank 21. One end of the second gas tank 21 is fixedly connected to the first gas pipe 22, and the end of the first gas pipe 22 away from the second gas tank 21 is installed with a three-way connector 23. The three-way connector 23 is installed with a rotating nozzle 24 and a second gas pipe 25, and the end of the second gas pipe 25 away from the three-way connector 23 is installed with a mask 26. The rotating nozzle 24 is used to spray out the high-pressure air in the second gas tank 21 to expel the harmful gas near the head of the underground mine workers. The second gas pipe 25 provides the air in the second gas tank 21 to a single underground mine worker through the mask 26.

[0052] The rotating nozzle 24 is an expulsion solution for multiple people. The gas ejected by the rotating nozzle 24 can expel the gas near multiple underground mine workers and reduce the amount of gas inhaled by the underground mine workers. The mask 26 is a rescue solution for a single person. Both provide safety protection for the underground mine workers during the evacuation process and prevent the underground mine workers from inhaling too much gas and affecting their health.

[0053] In order to ensure that the mask 26 is not contaminated by dust in the frame, Figure 8 As shown, the lower end of the first water tank 5 is fixedly connected with a receiving groove 27, and the mask 26 is placed in the receiving groove 27. A rubber ring 2701 matching the mask 26 is fixedly connected to the receiving groove 27, and the rubber ring 2701 contacts the outer wall of the mask 26, so that the mask 26 and the receiving groove 27 are in a closed space. When the mask 26 is needed, the second geological anomaly detector starts the second gas storage tank 21, so that the gas in the second gas storage tank 21 is ejected from the mask 26. When ejected for the first time, it is in the form of a high-intensity gas column ejection, which pushes the mask 26 out of the receiving groove 27. The mask 26 is vertically downward due to gravity, so that the underground mine workers can take the mask 26.

[0054] When the mask 26 is used, the slider 2 moves along the movement trajectory of the underground workers, that is, the movement speed of the slider 2 can follow the escape speed of the underground workers, so that the mask 26 can always provide air to the underground workers. Figure 5 As shown, the lower end of the first water tank 5 is also fixedly connected to a light indication structure 54, which can project key evacuation information to the front of the field of vision of the underground workers through optical reflection technology, so as to facilitate the underground workers to execute the evacuation route.

[0055] like Figure 10 to Figure 13 As shown, the first geological anomaly detector can discharge harmful gases in the mine, and the first geological anomaly detector is provided with a charging mechanism 43 that matches the second geological anomaly detector. The charging mechanism 43 can be used to replenish cooling liquid and compressed air to the second geological anomaly detector.

[0056] Specifically, Fig.10 As shown, the first geological anomaly detector includes a carrier 30, and a second set detector 31 is arranged at the front end of the carrier 30. The second set detector 31 can detect the underground environment such as gas, smell, obstacles, etc. When used for the first time, the carrier 30 cooperates with the second set detector 31 to enter the geological structure area that has not been entered, and detect the entered environment. After judging that there is no danger, the detector enters and takes samples to achieve more accurate detection.

[0057] like Fig.10 As shown, a baffle 42 for protecting the second set detector 31 is fixedly connected to the upper end surface of the carrier 30, and the side away from the second set detector 31 is a placement surface 3001, on which a seat 40 is installed. An armrest 41 is rotatably connected to the seat 40, and a person can sit on the seat 40 and be carried by the carrier 30. Generally, the armrest 41 is in a storage state, and the detector for detection is placed between the baffle 42 and the seat 40. Under the transportation of the carrier 30, manpower can be saved and the situation of manpower carrying large detectors can be reduced.

[0058] like Figure 10-11 As shown, the front end of the carrier 30 is provided with an exhaust mechanism 32, which can extract harmful gases in the frame. The rear end of the exhaust mechanism 32 is provided with an exhaust connector 34 matched therewith, and the exhaust connector 34 is used to connect a pipeline, through which harmful gases in the mine can be directly discharged. Among them, the exhaust mechanism 32 includes an exhaust panel 33, and the exhaust panel 33 can filter impurities to avoid the situation where there are too many impurities in the gas extracted by the exhaust mechanism 32, which causes the pipeline to be blocked.

[0059] like Figure 10 to Figure 12 As shown, a second water tank 37 is installed inside the carrier 30, and the second water tank 37 is installed in the carrier 30 as a cooling structure. A liquid inlet joint 35 and a liquid spray nozzle 36 matching the second water tank 37 are installed on the carrier 30. The liquid inlet joint 35 is used to connect a water pipe, and water enters the liquid inlet joint 35 from the water pipe, and then enters the second water tank 37 from the liquid inlet joint 35, and finally the water is discharged by the liquid spray nozzle 36. In this process, the water can take away the heat of the carrier 30 to achieve heat dissipation of the carrier 30.

[0060] The water can also be stored in the second water tank 37. The capacity of the second water tank 37 is greater than that of the first water tank 5. Generally, the capacity of the second water tank 37 is 2 to 3 times that of the first water tank 5. Even if the liquid inlet connector 35 is not connected to a water pipe, the liquid in the second water tank 37 can be provided to the first water tank 5 to replenish the liquid in the first water tank 5.

[0061] The liquid spray nozzle 36 sprays water onto the ground, which can clean the working surface during daily use, while also keeping the working surface moist and reducing coal dust.

[0062] like Figure 10-11 As shown, a second oxygen supply mechanism 38 is also installed on the carrier 30, and the second oxygen supply mechanism 38 includes a first gas storage tank 39, and an air intake connector 3901 is fixedly connected to the first gas storage tank 39. Similarly, the air intake connector 3901 is used to connect the pipeline, and the air passes through the air intake connector 3901 and is transported to the second oxygen supply mechanism 38 through a compression pump (not shown in the figure). The second oxygen supply mechanism 38 is also connected to a liquid spray nozzle 36 (not shown in the figure) for providing air to the underground mine workers sitting on the seat 40.

[0063] like Figure 10 to Figure 13 As shown, a charging mechanism 43 is installed on the carrier 30, and the charging mechanism 43 includes two telescopic rods 46, one end of each of which is fixedly connected to the carrier 30. The other end of the telescopic rod 46 is fixedly connected to a male connecting mechanism 47. A third connecting pipe 44 is installed between one of the male connecting mechanisms 47 and the first air storage tank 39, and a fourth connecting pipe 45 is installed between the other male connecting mechanism 47 and the second water tank 37. The two male connecting mechanisms 47 are used to transport air and cooling liquid, respectively.

[0064] like Figure 7 As shown, the first water tank 5 is fixedly connected with a liquid inlet female connector 502 matching the male connector 47, the second gas storage tank 21 is fixedly connected with a first gas inlet pipe 28, and one end of the first gas inlet pipe 28 away from the second gas storage tank 21 is fixedly connected with a gas inlet female connector 29 matching the male connector 47. Both the liquid inlet female connector 502 and the gas inlet female connector 29 are fixedly arranged.

[0065] like Fig.14 As shown, when replenishing resources, the two male connection mechanisms 47 are aligned with the liquid inlet female head 502 and the air inlet female head 29 respectively. After alignment, the male connection mechanism 47 is lifted by the telescopic rod 46, so that the male connection mechanism 47 is plugged with the liquid inlet female head 502 and the air inlet female head 29 respectively, and the male connection mechanism 47 is connected with the liquid inlet female head 502 and the air inlet female head 29, and the resources can be replenished. When replenishing resources, the carrier 30 and the slider 2 can move in the same direction and at the same moving speed, without affecting the detection operation of the second geological anomaly detector.

[0066] like Fig.13As shown, the male connector 47 includes a second protective shell 48, the outer diameter of the second protective shell 48 is equal to the outer diameter of the liquid inlet female connector 502 and the air inlet female connector 29, the lower end of the second protective shell 48 is fixedly connected to a soft shell 49, and the end of the soft shell 49 away from the second protective shell 48 is fixedly connected to a first connecting plate 50. The second protective shell 48 and the soft shell 49 are both tubular, and the first connecting plate 50 blocks the end of the soft shell 49 away from the second protective shell 48. A second connecting plate 51 is slidably connected in the second protective shell 48, and a connecting male connector 53 is installed on the second connecting plate 51. The outer diameter of the connecting male connector 53 is slightly smaller than the inner diameter of the liquid inlet female connector 502 and the air inlet female connector 29, that is, the connecting male connector 53 can be inserted into the liquid inlet female connector 502 and the air inlet female connector 29. The end of the second protective shell 48 away from the soft shell 49 is fixedly connected to a rubber plug 4801.

[0067] When the male connector 47 is in use, the telescopic rod 46 first pushes the male connector 47 upward, the second protective shell 48 contacts the liquid inlet female connector 502 and the air inlet female connector 29, and the telescopic rod 46 pushes upward again, the spring 52 and the soft shell 49 are deformed, and the connecting male connector 53 moves to the end away from the soft shell 49 until the upper end of the connecting male connector 53 breaks through the rubber plugging surface 4801 and completes docking with the liquid inlet female connector 502 and the air inlet female connector 29. By providing the second protective shell 48 and the rubber plugging surface 4801, it can be ensured that the connecting male connector 53 will not be blocked by impurities during normal operation, and the situation in which the normal replenishment of the connecting male connector 53 is affected by impurities and coal dust is avoided.

[0068] When the coal mine working face geological anomaly detection device is used, the first geological anomaly detector is first used for initial detection. After ensuring that the environment is safe to enter, the detector enters and conducts a careful detection. The detection equipment required by the detector can be placed on the placement surface 3001. Even when a water injection drilling device is needed, the carrier 30 can also transport the water injection drilling device, and the carrier 30 can provide water to the water injection drilling device.

[0069] After the initial exploration is completed, the second geological anomaly detector is installed on the top wall of the working face, and the inspection of the working face is completed by the second geological anomaly detector. And the working face can be moistened and dusted by the heat dissipation fan 7 and the second nozzle 14, reducing the impact of dust in the coal mine on coal mining. In addition, when gas suddenly gushes from somewhere, the second geological anomaly detector can rush to the place of gushes in the first time, and generate a water mist barrier by spraying to slow down the spread of gas in the mine, providing protection for the evacuation of underground workers.

[0070] For the underground workers who did not evacuate immediately, the second geological anomaly detector can detect their location and move to the location of the underground workers, providing air to the underground workers through the rotating nozzle 24 and the mask 26 to prevent the underground workers from inhaling too much gas and causing physical damage.

[0071] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
