[0002] A coal mine is an area where humans exploit coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. A mine is a general term for shafts, chambers, equipment, ground buildings and structures in the underground coal mine production system. Sometimes inclined shafts, vertical shafts, horizontal shafts, etc. in underground mine development are also called mines.

[0003] The process of coal mining will indirectly lead to carbon dioxide emissions. Carbon dioxide in mines will not only pollute the environment but also have serious impacts on human health. There are also certain safety hazards in mines. In order to reduce the harm of carbon dioxide in mines, carbon dioxide storage devices are usually used to recycle and store the carbon dioxide generated by coal mining.

[0004] However, commonly used underground carbon dioxide storage devices lack certain safety protection measures. Coal mining will cause continuous rockfall, and the carbon dioxide storage devices often do not have anti-falling object protection structures.

[0034] like Figure 1-Figure 7As shown, this embodiment provides an embodiment of a portable device for storing carbon dioxide underground in a coal mine and a method of using the same.

[0035] A portable device for storing carbon dioxide underground in a coal mine, comprising a support frame 1, on which a carbon dioxide storage device 2 is fixedly mounted, an air inlet pipe 3 and an air outlet pipe 4 are fixedly mounted on the front of the carbon dioxide storage device 2, a protective structure 5 is provided on the support frame 1, the protective structure 5 comprises two first fixed plates 6 symmetrically mounted on the support frame 1, a first fixed frame 7 is fixedly mounted on the first fixed plate 6, a plurality of second fixed plates 8 are arranged between the two first fixed frames 7, a plurality of first protective plates 9 are arranged above the plurality of second fixed plates 8, the first protective plates 9 are connected to the second fixed plates 8 by a plurality of spring damping rods 10, a plurality of second fixed frames 11 mounted on the support frame 1 are arranged on both sides of the carbon dioxide storage device 2, and a second protective plate 12 is arranged on the second fixed frame 11. By setting the protective structure 5, the carbon dioxide storage device 2 can be protected. The multiple first protective plates 9 and second protective plates 12 include the carbon dioxide storage device 2. When falling rocks fall, the first protective plates 9 and the spring shock absorber rods 10 can resist and buffer the falling rocks from above, reducing the impact on the carbon dioxide storage device 2, and the second protective plates 12 can block the falling rocks from the side to avoid direct contact with the carbon dioxide storage device 2, thereby preventing the carbon dioxide storage device 2 from being damaged by falling rocks, and further preventing carbon dioxide from leaking therefrom.

[0036] In this embodiment, the second fixed plate 8 and the second protective plate 12 are both fixedly mounted with a first screw 13, and the inner walls of the first fixed frame 7 and the second fixed frame 11 are both movably mounted with a nut 14 threadedly connected to the first screw 13, and a plurality of first protective plates 9 are distributed in a trapezoidal shape above the carbon dioxide storage device 2, and a plurality of fixed blocks 15 are symmetrically mounted at the bottom of the support frame 1, a screw 16 is movably mounted between two adjacent fixed blocks 15, and a motor 17 is mounted at one end of the screw 16, and a moving block 19 slidably mounted through a slider 18 is provided at the bottom of the support frame 1, and the two moving blocks 19 are symmetrically mounted on the screw 16 through threads, and a support plate 20 is provided below the screw 16, and a support rod 21 is movably mounted at the bottom of the moving block 19, and one end of the support rod 21 is movably connected to the support plate 20. The arrangement of the first screw 13 and the nut 14 facilitates the installation and disassembly of the first protective plate 9 and the second protective plate 12, and can be replaced when the first protective plate 9 and the second protective plate 12 are damaged.

A plurality of cone blocks 30 are fixedly installed on the surface of the other end of the second screw 25, and the cone block 30 is provided with anti-slip grooves. By setting the hydraulic cylinder 22 and the fastening plate 23, after the support frame 1 and the carbon dioxide storage device 2 are stably placed, the hydraulic cylinder 22 is started to extend its output end to fit the fastening plate 23 to the well wall, and then the fixing piece is inserted into the fixing hole of the fastening plate 23 to make it tightly connected to the well wall, so that the support frame 1 and the carbon dioxide storage device 2 can be fixed as a whole to prevent them from being more firmly on the underground working surface. By setting the fixing frame 24, the second screw 25, the fastening block 26 and the sealing gasket 27, the air inlet pipe 3 or the air outlet pipe 4 can be firmly connected to the delivery pipe, and the delivery pipe and the air inlet pipe 3 are connected. Or after the air outlet pipe 4 is docked, the two second screws 25 are rotated to drive the two fastening blocks 26 to approach each other to clamp and fix the delivery pipe, so that the delivery pipe is closely connected with the air inlet pipe 3 or the air outlet pipe 4 to prevent loosening. The sealing gasket 27 can prevent carbon dioxide from leaking from the connection. Through the setting of the limit block 28, the limit groove 29 and the cone block 30, the limit block 28 and the limit groove 29 can limit the fastening block 26 so that it can move up and down smoothly and avoid rotating with the second screw 25. The setting of the cone block 30 can increase the friction at one end of the second screw 25, which is convenient for the staff to operate and twist.

[0038] In this embodiment, a mounting frame 31 is fixedly installed on the carbon dioxide storage device 2, and a pressure detection gauge 32 is fixedly installed on the mounting frame 31. One end of the pressure detection gauge 32 extends into the interior of the carbon dioxide storage device 2. A third fixing frame 33 is fixedly installed on the top and bottom of the mounting frame 31. An alarm 34 is fixedly installed on the third fixing frame 33. A hydraulic rod 35 electrically connected to the pressure detection gauge 32 is fixedly installed inside the third fixing frame 33, and a pressing block 36 is fixedly installed on the output end of the hydraulic rod 35. By arranging the mounting frame 31, the pressure detection gauge 32, the third fixing frame 33, the alarm 34, the hydraulic rod 35 and the pressing block 36, the pressure detection gauge 32 is arranged on the carbon dioxide storage device 2 so as to detect the pressure in the carbon dioxide storage device 2 in real time to ensure that the pressure in the carbon dioxide storage device 2 is within a safe range, and the alarm 34 is arranged so as to give an alarm reminder when the pressure in the carbon dioxide storage device 2 is abnormally too high or too low. When the pressure detection gauge 32 detects that the pressure in the carbon dioxide storage device 2 is too high, the hydraulic rod 35 located above is controlled to start, so that the hydraulic rod 35 is extended to drive the pressing block 36 to press and open the alarm 34 to give an alarm, and when the pressure is too low, the hydraulic rod 35 located below is controlled to start, so that the hydraulic rod 35 is extended to drive the pressing block 36 to press and open the alarm 34 to give an alarm.

[0039] In this embodiment, if Figure 1-Figure 7 As shown, the working process of a portable device for storing carbon dioxide in coal mines and a method for using the same provided in this embodiment is as follows:

[0040] Step 1: transport the support frame 1 and the carbon dioxide storage device 2 as a whole to the underground working surface through the mine transportation system. When the support frame 1 and the carbon dioxide storage device 2 are placed on the underground working surface, start the motor 17 to drive the screw rod 16 to rotate, so that the screw rod 16 drives the two moving blocks 19 to move relatively, so that the two moving blocks 19 push the support plate 20 through the support rod 21, so that the two support plates 20 contact the ground to support the support frame 1 and maintain balance;

[0041] Step 2: After the support frame 1 and the carbon dioxide storage device 2 are balanced and placed on the underground working surface, the hydraulic cylinder 22 is started to extend its output end to fit the fastening plate 23 to the well wall, and then a fixing piece is inserted into the fixing hole of the fastening plate 23 to make it tightly connected to the well wall, so as to support and fix the support frame 1 and the carbon dioxide storage device 2;

[0042] Step 3, multiple first protective plates 9 and second protective plates 12 are installed on the first fixing frame 7 and the second fixing frame 11 through the first screw 13, and then the nut 14 is turned to be threadedly connected with the first screw 13 to fix the multiple first protective plates 9 and the second protective plates 12 on the first fixing frame 7 and the second fixing frame 11, and the multiple first protective plates 9 and the second protective plates 12 wrap the carbon dioxide storage device 2 to protect it;

[0043] Step 4: Finally, dock the delivery pipe for recovering carbon dioxide with the air intake pipe 3, rotate the two second screws 25 to drive the two fastening blocks 26 to approach each other to clamp and fix the delivery pipe, so that the delivery pipe is closely connected to the air intake pipe 3 to recover and store carbon dioxide.

[0044] In summary, in this embodiment, according to a portable device for storing carbon dioxide underground in a coal mine and a method for using the same, the first screw 13 and the nut 14 are provided to facilitate installation and disassembly of the first protective plate 9 and the second protective plate 12, and the first protective plate 9 and the second protective plate 12 can be replaced when they are damaged. The first screw 13 on the second fixing plate 8 and the second protective plate 12 are respectively inserted into the first fixing frame 7 and the second fixing frame 11, and then the nut 14 is rotated to be threadedly connected with the first screw 13. The installation of the first protective plate 9 and the second protective plate 12 is completed under the tightening of the thread. After the nut 14 is rotated in the opposite direction to separate from the first screw 13, the disassembly of the first protective plate 9 and the second protective plate 12 can be completed. By arranging multiple first protective plates 9 in a trapezoidal distribution, it is possible to facilitate falling rocks on the first protective plate 9. After that, it can roll to both sides to avoid accumulation on the top of the first protective plate 9, so as to reduce the pressure on the first protective plate 9. Through the arrangement of the fixed block 15, the screw rod 16, the motor 17, the slider 18, the moving block 19, the support plate 20 and the support rod 21, the support frame 1 and the carbon dioxide storage device 2 can be stably supported and placed on the underground working surface as a whole. The working surface inside the mine is generally uneven. When the support frame 1 and the carbon dioxide storage device 2 are prevented from being on the working surface, the motor 17 is started to drive the screw rod 16 to rotate, so that the screw rod 16 drives the two moving blocks 19 to move relative to each other, and the moving block 19 can push the support plate 20 through the support rod 21 under the limiting action of the slider 18 and the transmission action of the screw rod 16, so that the two support plates 20 contact the ground to support the support frame 1 and maintain balance, so that it can be placed stably to avoid tipping over. By setting the hydraulic cylinder 22 and the fastening plate 23, after the support frame 1 and the carbon dioxide storage device 2 are stably placed, the hydraulic cylinder 22 is started to extend its output end to fit the fastening plate 23 to the well wall, and then the fixing piece is inserted into the fixing hole of the fastening plate 23 to make it tightly connected to the well wall, so that the support frame 1 and the carbon dioxide storage device 2 can be fixed as a whole to prevent them from being more firmly on the underground working surface. By setting the fixing frame 24, the second screw 25, the fastening block 26 and the sealing gasket 27, the air inlet pipe 3 or the air outlet pipe 4 can be firmly connected to the delivery pipe, and the delivery pipe and the air inlet pipe 3 are connected. Or after the air outlet pipe 4 is docked, the two second screws 25 are rotated to drive the two fastening blocks 26 to approach each other to clamp and fix the delivery pipe, so that the delivery pipe is closely connected with the air inlet pipe 3 or the air outlet pipe 4 to prevent loosening. The sealing gasket 27 can prevent carbon dioxide from leaking from the connection. Through the setting of the limit block 28, the limit groove 29 and the cone block 30, the limit block 28 and the limit groove 29 can limit the fastening block 26 so that it can move up and down smoothly and avoid rotating with the second screw 25. The setting of the cone block 30 can increase the friction at one end of the second screw 25, which is convenient for the staff to operate and twist.
