Description

Technical Field

[0001] The present invention relates to the technical field of coal mine safety protection devices, and specifically relates to a safety protection device for coal mines with water prevention and control and its usage method. Background Art

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas, generally divided into underground coal mines and surface coal mines. When excavating in a coal mine underground, groundwater or accumulated water in the coal mine underground instantaneously enters the mine roadway from the penetrated area under huge pressure, thereby triggering accidents, resulting in casualties, and seriously affecting the safe production of coal mines. Therefore, during the coal mine operation process, in order to avoid the occurrence of coal mine water seepage incidents, it is necessary to carry out safety protection operations for water prevention and control during coal mine mining.

[0003] The existing Chinese patent application with the publication number of CN118774958A discloses a safety protection device for coal mines with water prevention and control and its usage method, including a working platform, a positioning column, a buoy warning component, a positioning insertion pipe, a first water prevention and control safety protection component, and a second water prevention and control safety protection component; a working platform for keeping the positioning column, the buoy warning component, and the positioning insertion pipe balanced, stably installed, with a first water prevention and control safety protection component sleeved on the periphery of the working platform for primary sealing and prevention protection against the overflow of the water gushing point, and a second water prevention and control safety protection component sleeved on the periphery of the first water prevention and control safety protection component for secondary prevention of the overflow of the water gushing point and for further prevention, pressure relief, and diversion protection. The working platform is circumferentially inserted and installed with a positioning insertion pipe for deep piling and strengthening the prevention of water flow around the water gushing point, and a positioning column for deeply detecting the center of the water gushing point is provided at the center of the working platform; in this invention, when carrying out prevention and control, the water gushing point surges, the water flow gradually spreads out, the water flow squeezes the floating detection pipe, the water pressure sensor transmits a signal to the controller, the water flow impacts the airbag ball, causing its detection rod to gradually rise along the inside of the buoy cylinder, observing the marking scale, and simultaneously the humidity sensor feeds back to the flashing light for warning, observing through the display screen, and the signal is transmitted to the background through the antenna. When the water flow gradually surges too much into the first circumferential valve, after a period of time, the first push cylinder drives the first push rod to drive the first circumferential valve to gradually rise, the water flow enters the second circumferential valve, and is sequentially diverted through the pressure relief holes to reduce the impact of the water flow and form prevention and control management.

[0004] However, the safety protection device for water prevention and control has the following defects in specific use:

[0005] 1. When the existing water control safety protection device protects the mine shaft during coal mining operations, it generally operates by triggering a safety alarm device through the impact of groundwater. It conducts safety alarm operations when groundwater leaks in the coal mine to improve safety. However, during actual coal mine mining operations, groundwater leakage is generally caused by local seepage points driving cracks. As time goes by, the groundwater seeping out from the seepage points increases continuously, affecting the safety of workers. At this time, traditional devices generally can only monitor the phenomenon of whether there is water seepage, and it is difficult to intuitively know the seepage rate. As a result, after the water seepage operation occurs, it is difficult to determine whether to arrange for evacuation or repair the seepage point;

[0006] 2. When the existing water control safety protection device is in use, it is generally installed on the top of the excavated mine shaft. However, in the traditional scheme for installing the device, the installed device is prone to floating and moving problems due to the accumulation of groundwater seeping out from the seepage points, resulting in a slow response of the safety protection device to the occurrence of coal mine water seepage events and low safety.

[0043] The present invention also provides a usage method of a safety protection device for preventing and controlling water in coal mines, including the following steps:

[0044] S1. Installation of the safety protection device: When carrying out coal mine mining operations, it is necessary to carry out water prevention and control operations on the coal mine mining environment to reduce the impact of water hazard accidents on coal mine production. At this time, the device is installed on the inner top of the corresponding wellbore through the gear positioning component;

[0045] S2. Sealing of the wellbore: After completing the installation operation of the device, start the airbag sealing component to operate and seal the wellbore where the installation device is located to reduce the problem of water leakage during the actual monitoring of water hazard accidents;

[0046] S3. Coal mine water prevention and control monitoring: The pressure generated by the water flow in the wellbore will drive the operation of the water prevention and control safety alarm mechanism. When there is a problem of water seepage, an alarm is issued through the water prevention and control safety alarm mechanism to remind coal mine workers and ensure the safety of coal mine mining.

[0047] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0048] 1. In a safety protection device and method for preventing and controlling water in coal mines, when water seepage occurs in a coal mine shaft, the groundwater squeezing force generated by the seepage can drive multiple vertical rods of different lengths and trigger protrusions to move up and down. The trigger protrusions and the trigger module can then contact and squeeze each other, triggering the alarm light and buzzer to operate, providing a safety alarm for the occurrence of water seepage and improving safety during coal mine operations. At the same time, vertical rods of different lengths drive the trigger module to operate at different times, and the trigger time interval can be used to detect the speed of water seepage at regular intervals, ensuring that when water seepage occurs, there is sufficient basis and time to arrange escape or repair the seepage point, resulting in higher safety.

[0049] 2. In the safety protection device for preventing and controlling water in coal mines and its use method, when detecting water seepage in coal mines, the device needs to be installed. At this time, multiple extrusion cams are driven by a DC motor to operate, and the multiple extrusion cams can be extended to the installation points inside the coal mine shaft to achieve the initial installation of the device. Afterwards, the servo electric cylinder located inside the extrusion cam can drive multiple side cams to operate, and insert the side cams in multiple directions into the interior of the installation points, thereby achieving multi-directional and multi-point installation and fixing operations of the device, reducing the probability of the device floating up due to the pressure of groundwater when water seepage occurs, and ensuring the accuracy of monitoring the occurrence of water seepage and the speed of water seepage;

[0050] 3. In a safety protection device for preventing and controlling water in coal mines and its method of use, an air gun can be used to inflate the sealed airbag, causing it to swell and sealing the gap between the device and the coal mine shaft. When groundwater seepage occurs, the groundwater can be blocked, ensuring sufficient time for workers to escape. At the same time, when groundwater seeps and squeezes the device, the thrust generated will cause the air pressure inside the sealed airbag to change. At this time, the air pressure detection module connected to the sealed airbag can detect this abnormal situation and issue a timely alarm;

[0051] 4. In the safety protection device for preventing and controlling water in coal mines and the method for use thereof, when the device is disassembled for maintenance, the extrusion protrusion and the side protrusion extending to the outside of the assembly shell can be extended to the inside of the assembly shell, ensuring that the well hole where the device is installed will not be damaged when the device is disassembled. When the maintenance is completed or another device is installed, there is no need to re-measure the installation position of the device and adjust the height position of the internal structure of the device, which makes the operation more convenient.

[0074] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0075] Embodiment 1

[0076] Please refer to Figures 1 - 12, A safety protection device for preventing and controlling water in coal mines includes an assembly housing 10 and a base 20. The base 20 is installed at the bottom of the assembly housing 10. An airbag sealing component 30 extending to the top of the assembly housing 10 is installed on the outside of the base 20. A gear positioning component 40 extending to the outside is installed inside the assembly housing 10. The gear positioning component 40 extends into the interior of the coal mine shaft. A water prevention and control safety alarm mechanism 50 is installed at the center of the interior of the assembly housing 10 and the base 20. The bottom of the water prevention and control safety alarm mechanism 50 extends below the base 20, and the top of the water prevention and control safety alarm mechanism 50 extends above the assembly housing 10. Among them, the water prevention and control safety alarm mechanism 50 includes a bottom piston component 60 installed inside the assembly housing 10 and the base 20. The bottom piston component 60 extends into the interior of the coal mine shaft. The bottom piston component 60 is arranged inside the gear positioning component 40; a lifting component 70 is installed above the bottom piston component 60. The bottom piston component 60 extends to the top of the lifting component 70. A plurality of contact safety alarm components 80 are installed inside the lifting component 70. The contact safety alarm components 80 match the bottom piston component 60.

[0077] The above working principle: When carrying out coal mining operations, it is necessary to excavate the coal mine to generate a shaft. At this time, the device is stably and firmly installed inside the shaft through the gear positioning component 40. Then, the airbag sealing component 30 seals the gaps at the connection between the two, reducing the probability of leakage of external gas and internal groundwater. At the same time, during the safety protection operation of preventing and controlling water, the accumulation of groundwater will squeeze the bottom piston component 60, and according to the amount and speed of the groundwater accumulation, the contact safety alarm component 80 is triggered to operate. On the one hand, it monitors whether there is water seepage in the coal mine shaft, and on the other hand, it monitors the speed of water seepage of the groundwater, ensuring that the staff can arrange to escape or repair the seepage point according to the actual situation of the water seepage, with higher safety.

[0078] In the present invention, through the design of the gear positioning component 40, it is possible to fix multiple points in multiple directions inside the shaft, reducing the probability that the device floats due to the pressure of groundwater accumulation when there is groundwater seepage.

[0079] Specific reference Figure 7The airbag sealing assembly 30 includes an air gun 301, which is installed on one side of the eccentric top of the assembly shell 10. The output end of the air gun 301 is set through the assembly shell 10, and the bottom of the output end of the air gun 301 is connected to a sealing airbag 302, wherein the sealing airbag 302 is installed at the eccentric bottom of the assembly shell 10, and a base 20 is provided on the inner side of the sealing airbag 302; an air pressure detection module 303, the air pressure detection module 303 is connected to the sealing airbag 302, and the air pressure detection module 303 is installed on the other side of the eccentric top of the assembly shell 10.

[0080] In the present invention's coal mine water safety device, after installation, the air gun 301 is activated, forcing ambient air into the interior of the sealing airbag 302, causing it to inflate and seal the gap between the device and the inner wall of the well. Simultaneously, when groundwater comes into contact with the device, an upward buoyancy force is generated, pushing the device forward. This creates a tendency for friction between the sealing airbag 302 and the inner wall of the well, squeezing the sealing airbag 302. This squeezing of the sealing airbag 302 causes localized changes in the gas within it, which the air pressure detection module 303 can detect.

[0081] Specific reference Figure 4 、 Figure 5 and Figure 6 The gear positioning assembly 40 includes a DC motor 401, which is mounted on the side of the bottom piston assembly 60. The output end of the DC motor 401 is connected to a first gear 402, which is rotatably connected to the eccentric point inside the assembly shell 10; an external gear 403, which is meshed and connected to the side of the first gear 402, and is rotatably connected to the inside of the assembly shell 10. The bottom piston assembly 60 is provided on the inner side of the external gear 403; a protrusion 404, which is mounted on the top of the external gear 403, and a plurality of protrusions 404 are provided. The top of the protrusion 404 is rotatably connected to an upper connecting rod 405, and the top of the upper connecting rod 405 is rotatably connected to a connecting arm 406; a mounting seat 407, which is rotatably connected to the outside of the connecting arm 406. The mounting seat 407 is mounted on the inner bottom of an extrusion protrusion 408, and the extrusion protrusion 408 extends to the outside of the assembly shell 10.

[0082] In an embodiment of the present invention, a servo electric cylinder 4081 is installed inside the extrusion convex rod 408. The output end of the servo electric cylinder 4081 is connected to a telescopic disc 4082. The telescopic disc 4082 is slidably connected to the inner wall of the extrusion convex rod 408. Among them, a pressing arm 4083 is rotatably connected to the bottom of the telescopic disc 4082. A plurality of pressing arms 4083 are arranged annularly and equidistantly. A side convex rod 4084 is movably connected to the bottom of the pressing arm 4083. Among them, the side convex rod 4084 is slidably connected to the extrusion convex rod 408, and the side convex rod 4084 extends to the outside of the extrusion convex rod 408.

[0083] In the above embodiment, when installing the device, start the servo electric cylinder 4081 to operate, driving the telescopic disc 4082 connected to the output end of the servo electric cylinder 4081 to move horizontally. At this time, when the telescopic disc 4082 moves horizontally, the pressing arm 4083 rotatably connected to its bottom will operate, thereby driving the side convex rod 4084 rotatably connected to the bottom of the pressing arm 4083 to move, and extending the top of the side convex rod 4084 into the inside of the well hole to achieve stable installation operation of the device.

[0084] In the safety protection device for preventing and controlling water in coal mines of the present invention, when installing the device, start the DC motor 401 to operate, driving the first gear 402 connected to the output end of the DC motor 401 to rotate, and causing the external gear 403 meshed with the outside of the first gear 402 to rotate. When the external gear 403 rotates, the protruding part 404 installed on its top will drive the upper connecting rod 405 to operate, and cause the connecting arm 406 rotatably connected to the outside of the upper connecting rod 405 to move. At this time, when the connecting arm 406 moves, the mounting seat 407 and the extrusion convex rod 408 rotatably connected to its side will telescopically move inside the assembly housing 10, moving the extrusion convex rod 408 into the inside of the well hole to achieve the installation operation of the device.

[0085] Specific reference Figure 8 and Figure 9 As shown in and, the bottom piston assembly 60 includes an intermediate cylinder 601. The intermediate cylinder 601 is installed at the center inside the assembly housing 10 and the base 20. A plurality of inner protrusions 602 are installed inside the intermediate cylinder 601. The inner side of the intermediate cylinder 601 is slidably connected to a lifting disc 603 through the inner protrusions 602; a lower connecting rod 604, the lower connecting rod 604 is fixedly installed at the bottom of the lifting disc 603. The lower connecting rod 604 extends to the bottom of the intermediate cylinder 601. A sealing disc 605 is detachably installed at the bottom of the lower connecting rod 604 through bolts. Among them, the sealing disc 605 is located inside the coal mine well hole, and the cross-sectional area of the sealing disc 605 is the same as that of the coal mine well hole.

[0086] In an embodiment of the present invention, a plurality of vertical rods 6031 are installed above the lifting disc 603. The lengths of the plurality of lifting discs 603 are different. Among them, trigger protrusions 6032 are installed at the tops of the vertical rods 6031. The vertical rods 6031 penetrate through the lifting assembly 70, and the trigger protrusions 6032 extend into the internal of the contact safety alarm assembly 80. Among them, a plurality of assembly cavities 6011 are formed at the inner edge of the middle cylinder 601, and the lifting assembly 70 extending to the outside is installed inside the assembly cavities 6011.

[0087] In the above embodiment, when the lifting disc 603 moves up and down due to the extrusion force of groundwater, the plurality of vertical rods 6031 installed at its top will move up and down synchronously, and drive the trigger protrusions 6032 installed at the tops of the plurality of vertical rods 6031 to move up and down. At this time, the trigger protrusions 6032 arranged at different positions can be used to detect the seepage speed of groundwater.

[0088] In the safety protection device for preventing and controlling water in the coal mine of the present invention, when groundwater seeps, the increase in groundwater will squeeze the sealing disc 605 and drive the sealing disc 605 to move upward. When the sealing disc 605 moves upward, the lower connecting rod 604 connected to its top will drive the lifting disc 603 to move upward.

[0089] For specific reference Figure 9 、 Figure 10 and Figure 11 The lifting assembly 70 includes a lifting cylinder 701. There are a plurality of lifting cylinders 701. The plurality of lifting cylinders 701 are all installed inside the plurality of assembly cavities 6011. The output end of the lifting cylinder 701 is connected to an upper support 702. The upper support 702 is located above the middle cylinder 601; a lower guide rod 703. The lower guide rod 703 is installed at the edge of the bottom of the upper support 702. There are a plurality of lower guide rods 703. The lower guide rods 703 and the lifting cylinders 701 are arranged alternately. The lower guide rod 703 extends into the plurality of assembly cavities 6011. Among them, a spring 7031 is installed at the bottom of the lower guide rod 703. The spring 7031 is installed at the inner bottom of the assembly cavity 6s011. A plurality of contact safety alarm assemblies 80 are installed inside the upper support 702. The vertical rod 6031 and the trigger protrusion 6032 penetrate through the upper support 702.

[0090] In the safety protection device for preventing and controlling water in the coal mine of the present invention, when monitoring the water seepage problem, the lifting cylinder 701 can be started to operate, driving the upper support 702 connected to the output end of the lifting cylinder 701 to move up and down, and adjusting the position and height of the contact safety alarm assembly 80 according to the actual situation. The design of the lower guide rod 703 and the spring 7031 can guide the up and down movement of the upper support 702 to ensure the stability and balance of the upper support 702.

[0091] Embodiment 2

[0092] Based on the above embodiments, it is found that during use, traditional safety protection devices generally can only monitor whether water seeps, and it is difficult to intuitively know the speed of coal mine water seepage. As a result, after the coal mine water seepage occurs, it is difficult to determine in a timely manner whether to arrange for evacuation or repair the seepage point.

[0093] For this reason, specifically referring to Figure 11 and Figure 12 , the contact safety alarm component 80 includes an inner cylinder 801. The inner cylinder 801 is installed inside the upper support 702. A trigger protrusion 6032 is movably arranged inside the inner cylinder 801.
