[0022] Reference Figure 1 The embodiment of the present application proposes an underground gas collection device 100 for plateau hot springs, which includes a gas collection part 110, a gas cooling part 120 and a gas storage part 130, wherein the gas collection part 110 is used to collect underground gas, and after being cooled by the gas cooling part 120, it is stored in the gas storage part 130, the gas cooling part 120 is made of high temperature resistant and corrosion resistant material, and the cooling section 121 of the gas cooling part 120 is spiral.

[0023] Specifically, as described above, the underground gas collection device 100 provided in the embodiment of the present application is used for underground gas from plateau hot springs. The hot spring gas has high temperature and strong corrosiveness. The hot spring gas is collected by the gas collection part 110 and cooled by the gas cooling part 120 before being transported to the gas storage part 130 for subsequent detection work. Therefore, in the underground gas collection device 100 provided in the embodiment of the present application, the gas cooling part 120 is made of high temperature resistant and corrosion resistant material, so as to ensure the corrosion resistance and high temperature resistance of the gas collection device 100 in the extreme environment of the plateau, and ensure the safety and reliability of the collection process, and the cooling section 121 of the gas cooling part 120 is spirally shaped, which increases the heat exchange area between the gas and the coolant, so that the collected high temperature gas can be quickly cooled to prevent changes in the gas composition and damage to the equipment.

[0024] In summary, the underground gas collection device 100 for plateau hot springs provided in the embodiment of the present application can ensure the stability and accuracy of the collected gas samples in a high temperature environment, and the design of the underground gas collection device 100 can improve the simplicity of actual operation and reduce the complexity and risk of manual operation.

[0025] It should be noted that the high temperature and corrosion resistant materials mentioned above refer to materials that can stably work in high temperature and corrosive environments, such as ceramics, copper, alloy materials or Teflon (polytetrafluoroethylene, PTFE) and the like.

[0026] Furthermore, in some embodiments of the present application, the gas cooling section 120 also includes an air inlet section 122 and an air outlet section 123, one end of the air inlet section 122 of the gas cooling section 120 is connected to the gas collecting section 110, the other end of the air inlet section 122 of the gas cooling section 120 is connected to the cooling section 121, one end of the air outlet section 123 of the gas cooling section 120 is connected to the cooling section 121, and the other end of the air outlet section 123 of the gas cooling section 120 is connected to the gas storage section 130.

[0027] Specifically, Figure 1 As shown, the underground gas collected by the gas collecting section 110 passes through the air inlet section 122 of the gas cooling section 120, enters the cooling section 121 of the gas cooling section 120 for cooling, and is transported to the gas storage section 130 for storage through the air outlet section 123 of the gas cooling section 120, thereby forming a complete airflow path to ensure that the underground gas collected from the plateau hot springs can be transported to the gas storage section 130, prevent the gas sample from mixing with the outside air, and ensure the purity and completeness of the sample.

[0028] Furthermore, in some embodiments of the present application, the gas cooling part 120 is a double-layer structure, and the gas cooling part 120 includes an inner pipe and an outer pipe, the inner pipe is used to transmit underground gas, and the outer pipe is used to transmit coolant.

[0029] Specifically, the inner pipe of the cooling part 120 is used for gas circulation, while the outer pipe is used for coolant circulation, which not only improves the efficiency of gas collection, but also can effectively control the temperature of the gas through the coolant circulation system, thereby reducing the changes in gas composition caused by temperature changes and ensuring the purity of the gas sample.

[0030] It should be noted that the coolant mentioned above is usually liquid water, but the coolant can also be made of other substances, depending on the actual situation and is not limited here.

[0031] Furthermore, in some embodiments of the present application, the gas cooling portion 120 is made of a double-layer metal copper tube after high-temperature annealing.

[0032] Specifically, the gas cooling unit 120 is made of a double-layer metal copper tube after high-temperature annealing. The copper tube can achieve a high vacuum state through vacuum sealing techniques such as cold welding due to its good ductility and plasticity, thereby ensuring the sealing of the gas sample. This is particularly important for collecting rare gases (such as helium), because the permeability of rare gases in metal materials is extremely low, and the use of copper tubes can effectively maintain the purity of gas samples. In addition, copper tubes have good high temperature resistance and corrosion resistance, which is particularly important for high-temperature and corrosive gas environments such as plateau hot springs. Copper tubes can maintain performance under such extreme conditions to ensure the safety and reliability of the collection process. The gas samples collected by copper tubes are convenient for transportation and storage, which is very critical for situations where samples need to be transported from the collection site to the laboratory for analysis. The firmness and sealing of copper tubes ensure the integrity of samples during transportation. In addition, copper tubes can be bent into different shapes as needed to adapt to different sampling environments and equipment configurations. High temperature annealing of copper tubes mainly refers to a heat treatment process in which the copper tubes are exposed to high temperature for a long period of time and then slowly cooled. The main purpose is to release stress, increase material ductility and toughness, and produce special microstructures.

[0033] Further, refer again to Figure 1 In some embodiments of the present application, the gas collecting part 110 is in an inverted funnel shape, the wide mouth 111 of the gas collecting part 110 is used to collect underground gas, and the narrow mouth 112 of the gas collecting part 110 is connected to the air inlet section 122 of the gas cooling part 120.

[0034] Specifically, the wide mouth 111 of the inverted funnel-shaped gas collecting section 110 is immersed in the plateau hot spring, thereby ensuring that as much underground gas as possible is sucked in. The underground gas overflowing from the hot spring flows into the narrow mouth 112 through the wide mouth 111, and enters the gas cooling section 120 through the air intake section 122 of the gas cooling section 120, and is finally transported to the gas storage section 130.

[0035] Furthermore, in some embodiments of the present application, the gas collecting portion 110 is made of a metal copper tube after high-temperature annealing.

[0036] As mentioned above, the metal copper tube has the advantages of high sealing, high temperature resistance and corrosion resistance, easy transportation and storage, and flexibility of operation. It can also improve the collection efficiency and avoid air pollution. The metal copper tube after high temperature annealing has better ductility and toughness, thereby ensuring the stability of the gas collection part 110 to improve the purity and stability of the gas sample.

[0037] Furthermore, in some embodiments of the present application, liquid water is stored inside the gas storage unit 130 to collect underground gas by a drainage method.

[0038] like Figure 1 As shown, liquid water is stored inside the gas storage part 130. When the liquid water is extracted, negative pressure is formed in the gas storage part 130, thereby sucking the underground gas into the gas storage part 130. The gas storage part 130 collects the underground gas by the drainage method, which can improve the purity of the gas sample and avoid mixing with other gases.

[0039] Furthermore, in some embodiments of the present application, the gas storage part 130 is an inverted tank body, and the gas storage part 130 includes an air inlet pipe 131 and an air outlet pipe 132, one end of the air inlet pipe 131 is connected to the air outlet section 123 of the gas cooling part 120, and the other end of the air inlet pipe 131 is arranged to be adjacent to the inner top wall of the gas storage part 130, and the air outlet pipe 132 is used to discharge the liquid water stored inside.

[0040] As described above, liquid water is stored in the gas storage section 130. When the liquid water is extracted, a negative pressure is formed in the gas storage section 130, thereby sucking the underground gas into the gas storage section 130 through the air inlet pipe 131. The air outlet pipe 132 is used to discharge the liquid water stored inside to form a negative pressure in the gas storage section 130. The gas storage section 130 collects underground gas through the above-mentioned arrangement, which can further improve the purity of the gas sample and avoid mixing with other gases.

[0041] Furthermore, in some embodiments of the present application, the gas storage unit 130 also includes an air inlet valve 133 and an air outlet valve 134, the air inlet valve 133 is arranged between the air inlet pipe 131 and the air outlet section 123 of the gas cooling unit 120, and the air outlet valve 134 is arranged on the air outlet pipe 132 of the gas storage unit 130.

[0042] Specifically, in the underground gas collection device 100 provided in the embodiment of the present application, the gas flow rate is controlled by adjusting the gas inlet valve 133 and the gas outlet valve 134 to control the gas accumulation speed in the gas storage part 130 and the drainage rate of the gas storage part 130, so as to improve the stability of the gas sample. At the same time, the dual control valve design can ensure the purity and integrity of the collected gas sample, and further improve the high accuracy of the gas sample component analysis.

[0043] Furthermore, in some embodiments of the present application, the underground gas collection device 100 further includes a liquid storage tank 140 , the liquid storage tank 140 is used to store liquid water, and the gas storage part 130 is inverted in the liquid storage tank 140 .

[0044] Specifically, the function of the liquid storage tank 140 is to store liquid water. When the underground gas collection device 100 is working, the gas storage part 130 will be filled with liquid water and inverted in the liquid storage tank 140. When the liquid water is extracted, a negative pressure will be formed in the gas storage part 130, thereby sucking the underground gas into the gas storage part 130 through the air inlet pipe 131, and the air outlet pipe 132 is used to discharge the liquid water stored inside into the liquid storage tank 140 to form a negative pressure inside the gas storage part 130, thereby ensuring the purity and integrity of the collected gas samples and further improving the high accuracy of the gas sample component analysis.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
