Description

Technical Field

[0001] The utility model belongs to the technical field of exploration equipment, in particular to a portable helium monitoring device for geological exploration. Background Art

[0002] The use of helium monitoring in geological exploration is an effective method, mainly used to detect the presence and distribution of underground gas. The applications of helium in geological exploration include natural gas exploration: helium can be used as an indicator gas to help identify potential natural gas reservoirs; rock and mineral analysis: by analyzing the isotope ratio of helium, the formation process and history of underground rocks can be understood; fluid movement monitoring: the migration of helium can reflect the movement of groundwater or oil and gas, helping to evaluate the development potential of resources.

[0003] Current helium monitors used in geological exploration often require access to mines for gas detection. Helium concentrations vary at different depths, and helium monitors can only penetrate deep into mines once for real-time monitoring. The presence of other gases during the detection process can lead to inaccurate detection data and a lack of comparative gas sampling data. To address this, we have developed a portable helium monitoring device for geological exploration that addresses these issues. Utility Model Content

After the detected signal is amplified, converted and analyzed, the helium concentration value will be displayed on the data display screen, and it can also be compared with the standard value to output the result, which can detect the geological information in the mine. Specific embodiment 2

[0032] See also Figure 1-6 On the basis of the specific embodiment 1, the driving assembly further includes a driving motor 12, which is installed inside the support shell 1, and the output end of the driving motor 12 is fixedly connected to the second gear 11. The top of the inflation tube 7 is connected to the delivery tube 13, and the top of the delivery tube 13 passes through the support shell 1 and is connected to the fixed box 14. The air inlet of the sampling pump 3 is connected to the fixed box 14 through a pipeline, and the surface of the delivery tube 13 is movably connected to the inner wall of the fixed box 14 through a bearing. The bottom of the fixed box 14 is fixedly connected to the support shell 1, and the sampling tube 6 is fixedly connected to the support ring 15. One side of the support ring 15 is fixed A first spring 16 is fixedly connected, and a sealing plug 17 is fixedly connected to the other end of the first spring 16. An air inlet 18 is provided at one end of the sampling tube 6, and a moving rod 19 is provided through the other end of the sampling tube 6. A baffle 20 is fixedly connected to one side of the moving rod 19, and a rubber plug 21 is fixedly connected to one side of the baffle 20. A through hole 22 is provided at one end of the sampling tube 6, and a second spring 23 is sleeved on the surface of the moving rod 19. The two ends of the second spring 23 are respectively fixedly connected to the moving rod 19 and the inner wall of the sampling tube 6. A traction ring 24 is fixedly connected to the top of the support shell 1, and a stabilizing rod is fixedly connected to the bottom of the support shell 1.

[0033] Specifically: there are four sampling tubes 6, which can store gas samples at different positions separately. One end of the sampling tube 6 is connected to the connecting shell 5 by a thread, and the other end of the sampling tube 6 passes through the outside of the supporting shell 1, which can be conveniently disassembled and separated after the sampling is completed. There is one air outlet 8 and four exhaust holes 9, which are evenly opened on the surface of the supporting tube 4. The first gear 10 is engaged with the second gear 11 to transmit the power of the driving motor 12. The surface of the delivery tube 13 is movably connected to the inner wall of the fixed box 14 through a bearing, and can maintain communication with the fixed box 14 when the delivery tube 13 rotates. The first spring 16 and the second spring 23 both have the function of compressing energy storage. The first spring 16 can elastically support the sealing plug 17, and the second spring 23 can elastically support the moving rod 19.

[0034] The working principle of the present utility model is as follows: the staff connects the support shell 1 to the external traction equipment through the traction ring 24, and then lowers the support shell 1 into the mine through the external traction equipment. When the support shell 1 is lowered to the specified detection distance, the sampling pump 3 can be started by the external controller. The sampling pump 3 drives the gas flow, and the air in the inflation tube 7 is extracted through the fixing box 14 and the delivery pipe 13, so that a negative pressure is formed inside the inflation tube 7. When the air outlet 8 is connected with the exhaust hole 9, the baffle 20 and the rubber plug 21 can be driven to move by the action of the negative pressure. When a negative pressure is formed inside the sampling tube 6, the sealing plug 17 can be driven to separate from the air inlet 18 by the action of the negative pressure, so that the gas in the mine enters the sampling tube 6.

[0035] The gas in the mine can be injected into the helium monitor 2 through the action of the sampling pump 3 to detect the gas sample in the mine. After the gas is injected into the helium monitor 2, the sampling pump 3 stops working. At this time, the first spring 16 resets the sealing plug 17, and the second spring 23 resets the moving rod 19, sealing the sampling tube 6. The gas sample at the current position can be retained, which is convenient for subsequent secondary detection and improves the accuracy of geological exploration data.

[0036] At the same time, the support shell 1 can be lowered to the next detection position in the mine through external traction equipment, and the drive motor 12 is started. The drive motor 12 cooperates with the first gear 10 to drive the second gear 11 to rotate, and the second gear 11 drives the inflation tube 7 to rotate 90 degrees clockwise, so that the air outlet 8 is aligned with the next set of exhaust holes 9, and then the sampling pump 3 is started again to perform gas sampling. Different positions in the mine can be tested, and gas samples at different positions can be retained at the same time, thereby improving the accuracy of geological exploration data.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
