Description

Technical Field

[0001] The utility model relates to the technical field of hot spring gas monitoring, in particular to a gas collecting hood for hot spring gas monitoring. Background Art

[0002] At present, earthquake precursor anomalies mainly include macroscopic anomalies such as abnormal seismic activity, abnormal seismic wave parameters, abnormal geophysical fields (including underground fluids, deformation, electromagnetic and satellite remote sensing, etc.), and some natural phenomena. Hot springs are mostly located on fault zones and have deep circulation characteristics. They can often sensitively reflect information about geothermal and tectonic changes deep in the crust. As an important object for earthquake underground fluid observation, they play an indispensable role in my country's earthquake prediction practice. Among them, changes in hot spring gases are one of the important indicators reflecting geological movements. When geological activities undergo drastic changes, such as earthquakes, the composition of hot spring gases will change dramatically. By monitoring the composition and content of hot spring gases, data support can be provided for geological activities, and thus provide an important basis for earthquake prediction.

[0003] The existing hot spring gas collection device has a relatively simple function and cannot detect the collected hot spring gas for subsequent processing, which will affect the accuracy of the sample gas analysis results. Therefore, we propose a gas collection hood for hot spring gas monitoring. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a gas collecting hood for hot spring gas monitoring, which collects sample gas in two ways, one way for detecting temperature and humidity, etc., and the other way for transmitting it to external monitoring equipment. The monitoring equipment automatically sets corresponding parameters according to the temperature and humidity detected by the detection device in the detection gas path before condensing and drying the sample gas, so as to facilitate the rapid processing of the collected sample gas, thereby improving the accuracy of the sample gas detection and analysis results, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gas collecting hood for hot spring gas monitoring, comprising a gas collecting hood and a gas collecting pipe, the gas collecting hood being trumpet-shaped, the gas collecting pipe being fixedly arranged on the side surface of the gas collecting hood at the smallest diameter and being connected thereto, a partition being fixedly arranged in the middle of the inside of the gas collecting hood, the partition being parallel to the axis of the gas collecting hood, dividing the inside of the gas collecting hood into two semi-conical shapes; a collecting pipe and a detecting pipe are respectively arranged in the gas collecting pipe, a detecting device is arranged in the detecting pipe, the collecting pipe and the detecting pipe respectively correspond to the two parts of the gas collecting hood separated by the partition; a core filler joint corresponding to the collecting pipe and the detecting pipe respectively is provided at the top of the gas collecting pipe, the core filler joint is connected to a ferrule joint, wherein the ferrule joint of the collecting pipe is connected to an external monitoring device, and the ferrule joint of the detecting pipe is connected to an exhaust device.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 The utility model provides a technical solution: a gas collecting hood for hot spring gas monitoring, comprising a gas collecting hood 1 and a gas collecting pipe 2. The gas collecting hood 1 is trumpet-shaped and has a larger bottom diameter, which can expand the collection area; the gas collecting pipe 2 is fixedly arranged on the side surface of the gas collecting hood 1 at the smallest diameter and is connected thereto, a partition 7 is fixedly arranged in the middle of the gas collecting hood 1, and the partition 7 is parallel to the axis of the gas collecting hood 1, dividing the interior of the gas collecting hood 1 into two semi-conical shapes, and a collecting pipe 3 and a detection pipe 4 are respectively arranged in the gas collecting pipe 2, and the collecting pipe 3 and the detection pipe 4 are respectively arranged in the gas collecting pipe 2. They correspond to the two parts of the gas collecting hood 1 separated by the partition 7. During collection, the gas collecting hood collects sample gas in two ways. The sample gas in the detection gas path is discharged through the exhaust device bottle after only the temperature and humidity are detected. The sample gas in the collection gas path is transported to the external monitoring equipment and then condensed and dried and then detected and analyzed by the gas chromatograph. The monitoring equipment automatically sets the corresponding parameters according to the temperature and humidity detected by the detection device in the detection gas path before the sample gas is condensed and dried, so as to facilitate the rapid processing of the collected sample gas, thereby improving the accuracy of the sample gas detection and analysis results.

[0020] The top of the gas collecting pipe 2 is provided with a core connector 5 corresponding to the collecting pipe 3 and the detection pipe 4 respectively. The core connector 5 is connected to the ferrule connector 6. Both the core connector 5 and the ferrule connector 6 can improve the sealing of the pipeline connection.

[0021] The ferrule connector 6 of the collecting tube 3 is connected to the external monitoring equipment, and is used to transport the collected sample gas to the external monitoring device for condensation and drying, and then detected and analyzed by the gas chromatograph; the ferrule connector 6 of the detection tube 4 is connected to the exhaust device, and is used to directly discharge the sample gas after temperature and humidity detection. Since the sample gas has been detected by multiple sensor components, the content of certain components in the gas may be reduced or impurities may be increased, so direct discharge avoids affecting the detection results of the hot spring gas.

[0022] In a preferred technical solution, a detection device is provided in the detection tube 4, and the detection device includes a temperature sensor 8 and a humidity sensor 9 installed inside the detection tube 4, which are respectively used to detect the temperature and humidity of the sample gas. The temperature sensor 8 and the humidity sensor 9 are both electrically connected to the processor in the external monitoring device, and the detection results can be directly transmitted to the processor of the monitoring device, which automatically controls the condensation drying equipment of the monitoring device according to a preset program.

[0023] The detection device further includes a barometer or an air pressure sensor disposed in the detection tube 4 for detecting the air pressure value of the sample gas.

[0024] According to a further preferred technical solution, the temperature sensor 8 and the humidity sensor 9 are installed in the middle or upper middle part of the detection tube 4 to be away from the gas collecting hood 1, thereby reducing the influence of the external environment and further improving the detection accuracy.

[0025] The temperature sensor 8, humidity sensor 9, barometer or pressure sensor, etc. used in this application are all commonly used devices in the prior art. Their specific structures, working principles, circuit connections, etc. are all well-known technologies and will not be described in detail here.

[0026] The preferred technical solution is that the exhaust device includes an air pump 11 installed on the upper outer side of the gas collecting pipe 2, the ferrule joint 6 of the detection tube 4 is connected to the exhaust duct 10, and the exhaust duct 10 is connected to the air inlet of the air pump 11. The sample gas in the detection tube 4 that has undergone temperature, humidity and pressure testing is extracted by the air pump 11 through the exhaust duct 10 and discharged into the external environment, and can also be discharged after entering the buffer bottle.

[0027] An optional technical solution is that a filter plate 12 is installed on the lower part of the inner surface of the gas collecting hood 1, and filter holes are evenly opened on the filter plate 12. The sample gas entering the gas collecting hood 1 is filtered by the filter plate 12, which can prevent impurities or surrounding insects, small animals, etc. from entering the gas collecting hood 1 when collecting hot spring gas and affecting the monitoring results. At the same time, it also avoids impurities or insects, small animals, etc. from causing damage to the gas collecting hood and monitoring equipment.

[0028] Further optionally, two filter plates 12 are provided, and the two filter plates 12 are symmetrically hinged on both sides of the partition 7. When the filter plates 12 need to be cleaned, the two filter plates 12 can be rotated downward and then cleaned, so that the upper and lower sides can be cleaned more comprehensively, and it is also convenient to maintain the inside of the air collecting hood.

[0029] Furthermore, two elastic blocks 13 are symmetrically fixed on the lower inner part of the air collecting hood 1, and the connecting line of the two elastic blocks 13 is perpendicular to the partition 7. When the filter plate 12 is flipped upward to be perpendicular to the partition 7, it is clamped on the inner side of the air collecting hood 1 by the elastic blocks 13, so that the filter plate 12 can be fixed more firmly.

[0030] The undisclosed parts of the present invention are all prior art, and their specific structures, materials and working principles will not be described in detail. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
