[0032] The present invention is described in further detail below with reference to the accompanying drawings:

[0033] like Figures 1 to 4 As shown, the utility model provides a carbon dioxide geological storage sealing monitoring device, including a support base 1, a limit portion 2, a mounting base 3, a detector 4, a sampling head 5, an annular plate 6, an outer gear ring 7, a mounting groove 8, a motor 9, a driving wheel 10, a display screen 11, an alarm light 12, a channel 13, a support sheet 14, a piston 15, a spring 16, a T-shaped air hole 17, a container 18, a pipeline 19, a filter tank 20 and activated carbon 21;

[0034] A limiting portion 2 is provided on the outside of the support seat 1. Both the support seat 1 and the limiting portion 2 are arranged in a ring shape. A mounting seat 3 is rotatably installed inside the support seat 1. A detector 4 is installed on the mounting seat 3. A plurality of sampling heads 5 distributed in a circular array are arranged through the mounting seat 3. The sampling head 5 and the detector 4 are connected by a transmission line. An adjustment mechanism is provided on the limiting portion 2, and the adjustment mechanism is connected to the mounting seat 3.

[0035] like Figure 2 and Figure 3As shown, the adjustment mechanism includes an annular plate 6, which is fixedly mounted on the mounting seat 3, and an outer gear ring 7 is fixedly mounted on the annular plate 6. A mounting groove 8 is provided inside the limiting portion 2, and the mounting groove 8 is connected to the outside world. A motor 9 is fixedly mounted in the mounting groove 8, and the output end of the motor 9 passes through the limiting portion 2. A driving wheel 10 is fixedly mounted on the output end of the motor 9, and the driving wheel 10 is meshed with the outer gear ring 7. The meshing transmission of the driving wheel 10 and the outer gear ring 7 driven by the motor 9 realizes the smooth rotation of the mounting seat 3 and the multi-point sampling head 5 thereon, which not only simplifies the operation process but also improves the monitoring efficiency. This integrated adjustment mechanism ensures that the sampling head 5 can accurately cover every corner of the gas injection well. Compared with traditional single-point monitoring, it significantly enhances the comprehensiveness and accuracy of the monitoring data, and provides a more reliable basis for the evaluation of the geological storage effect of carbon dioxide.

[0036] like Figure 2 As shown, detector 4 is equipped with a display screen 11 and an alarm light 12 mounted on top. Display screen 11 intuitively displays real-time monitoring data, allowing operators to instantly check the carbon dioxide concentration within the steam injection well, improving the convenience and efficiency of on-site operations. Furthermore, the top-mounted alarm light 12 immediately issues a warning when abnormal data or exceeding the standard is detected, effectively preventing potential safety hazards and enhancing the system's safety and emergency response capabilities.

[0037] like Figure 3 and Figure 4 As shown, the limiting portion 2 is provided with a pressure relief mechanism, which extends through the limiting portion 2 and the support base 1. The pressure relief mechanism includes a channel 13, which extends through the limiting portion 2 and the support base 1. A support plate 14 is fixedly mounted within the channel 13. A piston 15 is disposed within the channel 13. A spring 16 is fixedly connected between the piston 15 and the support plate 14. The piston 15 is provided with a T-shaped air hole 17. A container 18 is sheathed outside the channel 13. A pipe 19 is fixedly mounted on the container 18. A plurality of filter tanks 20 are provided at the bottom of the pipe 19. The pipe 19 is filled with a plurality of activated carbon 21. The pressure relief mechanism provided on the limiting portion 2, through the combination of the channel 13, the support plate 14, the piston 15, the spring 16, and the T-shaped air hole 17, can automatically release pressure when the internal pressure of the system abnormally increases, effectively protecting the entire monitoring device from damage. At the same time, the outer container 18 and its internal piping 19, filter tank 20, and activated carbon 21 not only provide additional buffering and purification space for released gases, but also remove any potentially harmful gases through adsorption by the activated carbon 21, ensuring a safe and environmentally friendly pressure relief process. This comprehensive design not only enhances the device's self-protection capabilities but also takes into account environmental protection requirements, enhancing the safety and sustainability of the entire CO2 geological storage and sealing monitoring system.

[0038] Working principle:

[0039] By putting the support seat 1 into the gas injection well, the limiting part 2 is clamped outside the gas injection well, the gas in the gas injection well is measured by the sampling head 5 and the data is transmitted to the detector 4, the measured data is displayed through the display screen 11, when the data reaches the early warning value, the alarm lamp 12 emits light and alarms; by setting a plurality of sampling heads 5, multi-point sampling detection can be realized, and the motor 9 drives the driving wheel 10 to rotate, the driving wheel 10 drives the outer gear ring 7 to rotate, and the mounting seat 3 can be driven to rotate, the sampling head 5 on the mounting seat 3 can be rotated to different positions, so that different positions in the gas injection well are measured. When the gas pressure in the gas injection well increases, the piston 15 can be driven to move upwards, the T-shaped gas hole 17 exhausts, the gas is discharged through the pipeline 19, the dust and impurities are filtered through the filter groove 20, and then the activated carbon 21 is used for adsorption and elimination of toxic and harmful substances. The carbon dioxide geological storage sealing monitoring device provided by the utility model realizes multi-point sampling detection, can cover a wider area, and further provides more comprehensive monitoring data.
