Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide monitoring, and in particular to an underground carbon dioxide storage monitoring device. Background Art

[0002] As global climate change intensifies, the monitoring and management of carbon dioxide (CO2), as a major greenhouse gas, becomes increasingly important. The development and application of underground carbon dioxide monitoring devices is the result of responding to climate change and environmental protection needs.

[0003] Traditional carbon dioxide storage monitoring devices often lack consistency during the drilling and gas collection process. Usually, the drilling operation is completed first, and then the gas collection operation is carried out. There is a time interval during this period, which makes it easy for the gas to be in contact with the atmosphere for a long time. Carbon dioxide and other components in the atmosphere will mix into the sample, changing the original composition of the sample and seriously affecting the detection quality. Summary of the invention

[0004] 1. Technical issues to be resolved

[0050] When the first servo motor 305 is turned on, it drives the driving gear 405 to rotate, and the driven gear 404 meshing with the driving gear 405 rotates synchronously, thereby driving the drilling rod 401 to rotate stably and carry out drilling operations. In this way, the drilling force of the drilling rod 401 can be controlled by the control panel 7 to ensure that it reaches the predetermined formation position smoothly. After the drilling rod 401 reaches the target formation, the control panel 7 starts the air pump 11 of the collecting pipe 402 to start collecting. The whole process is relatively coherent, which effectively avoids the long-term contact between the gas and the atmosphere. If the gas and the atmosphere are mixed for a long time, the carbon dioxide and other components in the atmosphere will be mixed into the sample, changing the original composition of the sample, thereby seriously affecting the detection quality.

[0055] The side of the return spring 506 away from the block 503 is fixed to the outer wall of the connecting block 502, and the outer wall of the slide rod 505 is slidably connected to the inner wall of the slide groove 507. One end of the return spring 506 is fixed to the block 503, and the other end is fixed to the connecting block 502. The slide rod 505 is slidably connected to the slide groove 507.

[0056] A carbon dioxide monitor 13 is fixedly connected to one side of the front end of the upper surface of the main body plate 1, a collecting box 12 is fixedly connected to one side of the upper surface of the main body plate 1 near the rear end of the carbon dioxide monitor 13, an air pump 11 is fixedly connected to one side of the upper surface of the main body plate 1 near the rear end of the collecting box 12, a first filter plate 14 is slidably connected to the front end of the upper inner wall of the collecting box 12, a second filter plate 15 is slidably connected to the front end of the upper inner wall of the collecting box 12, and the carbon dioxide monitor 13, the collecting box 12 and the air pump 11 are sequentially arranged on the upper surface of the main body plate 1, with a compact and reasonable layout.

[0057] A mounting shell 8 is fixedly connected to the rear end of one side of the upper surface of the main body plate 1, and a battery block 81 is arranged inside the mounting shell 8. A plurality of brake universal wheels 10 are fixedly connected to the lower surface of the main body plate 1. A mounting shell 8 is arranged at the rear end of the upper surface of the main body plate 1 and a battery block 81 is installed, which provides an independent power supply for the device. A plurality of brake universal wheels 10 are installed on the lower surface of the main body plate 1 to facilitate the movement and transportation of the device.

[0058] Working principle: When the control panel 7 starts the first servo motor 305, its output shaft drives the driving gear 405 to rotate. The driving gear 405 meshes with the driven gear 404, so that the driven gear 404 rotates synchronously. The driven gear 404 is fixed to the upper end of the outer wall of the drilling rod 401, thereby driving the drilling rod 401 to rotate stably and carry out drilling operations. The operator can adjust the speed and direction of the first servo motor 305 through the control panel 7, and then control the drilling force and direction of the drilling rod 401 to ensure that it reaches the predetermined formation position smoothly;

[0059] The collecting pipe 402 is arranged inside the drilling rod 401. After the drilling rod 401 reaches the target formation, it is ready to collect gas. At this time, when it is necessary to collect gas, the first servo motor 305 is started again, which drives the electric telescopic rod 501. The electric telescopic rod 501 is fixedly connected to the lower part of the inner wall of the drilling rod 401. Its telescopic action drives the connecting block 502 to move. The sliding rods 505 fixed at both ends of the outer wall of the connecting block 502 slide in the sliding grooves 507 opened at both ends of the lower part of the other side of the inner wall of the drilling rod 401 to ensure that the connecting block 502 moves smoothly. When the connecting block 502 moves, the multiple connecting rods 504 slidably connected at the edge of the other side of the outer wall drive the stopper 503 to move. The stopper 503 is processed with an angle wrapping, and flexibly retracts under the action of the force generated by the movement of the connecting block 502, so that the hole of the drilling rod 401 corresponding to the stopper 503 is smoothly opened, so as to prepare for the gas to enter the collecting pipe 402.

[0060] While the stopper 503 opens the hole, the control panel 7 starts the air pump 11, and the air pump 11 generates suction, so that the gas in the soil or stratum enters the collection pipe 402 through the internal space of the drilling rod 401. The gas collected by the collection pipe 402 is transported to the subsequent collection box 12 through the pipeline under the action of the air pump 11. The first filter plate 14 and the second filter plate 15 will filter particulate matter and dust, and then the carbon dioxide monitor 13 will monitor;

[0061] After the gas collection is completed, the electric telescopic rod 501 is started again to return to its original position, and the connecting block 502 moves accordingly. At this time, the block 503 returns to its original state under the elastic force of the reset spring 506. One end of the reset spring 506 is fixedly connected to the outer wall of the block 503 close to the side of the connecting block 502, and the other end is fixed to the outer wall of the connecting block 502. Its elastic force causes the block 503 to return to a state of close fit with the corresponding hole of the drilling rod 401, and re-establishes a tight seal to prevent the collected gas from backflowing or leaking, etc., to ensure the reliability and stability of the sample, and to provide a guarantee for the subsequent evaluation of the underground carbon dioxide storage status.
