Gas measuring device and method

Abstract

The present invention relates to the field of gas measurement technology, and specifically to a gas measurement device and method, which is connected to a base by fasteners or welding to form a closed space. The air intake pipe of the air intake assembly is responsible for guiding external gas into the measuring device. When working, the gas to be measured enters the base through the air intake pipe. Then it enters one side of the rotating plate through the air inlet on the base, and then fills the first air intake cavity or the second air intake cavity. After the gas volume in the air intake cavity is sufficient, the rotating plate is driven to rotate to drive the contact block to overcome the resistance generated by the block, so that the air intake cavity and the air outlet pipe are connected to discharge the gas. After that, the other air intake cavity is again inhaled, and the rotating plate is driven to rotate. In this way, the gas to be measured is collected in a cycle to ensure that the gas composition in the first cavity and the second cavity on both sides is consistent, avoiding the problem of inconsistent gas concentration on both sides caused by collecting a certain section of gas alone. In this way, dual-channel detection of gas is performed, which improves detection efficiency.

[0027] First embodiment

[0028] See also Figure 1 to Figure 6The present invention provides a gas measuring device, comprising a supporting component 101, an air intake component 102, a sampling component 103 and a detection component, wherein the supporting component 101 comprises a mounting seat and a housing 106, wherein the housing 106 is fixedly connected to the mounting seat and is located on the top of the mounting seat, wherein the air intake component 102 comprises an air intake pipe 107, an air intake shell 108 and a top partition plate 109, wherein the air intake shell 108 is arranged in the housing 106, wherein the top partition plate 109 is arranged in the air intake shell 108 and divides the air intake shell 108 into a first cavity 110 and a second cavity 111, wherein the air intake pipe 107 is arranged on the housing 106; wherein the sampling component 103 comprises a base 105, two stoppers 113, a rotating plate 114, a supporting shaft 115, a partition plate 116 and two air outlet pipes 117, wherein the base 105 It has an air inlet 118, the base 105 is arranged at the bottom of the air inlet shell 108 and is connected with the air inlet pipe 107, the support shaft 115 is rotatably arranged on the base 105, the rotating plate 114 has a first air inlet cavity 119 and a second air inlet cavity 120, the rotating plate 114 is fixed on the support shaft 115, and two stoppers 113 are slidably arranged on both sides of the base 105, and two contact blocks 122 are arranged on both sides of the rotating plate 114 corresponding to the stoppers 113; the partition plate 116 is fixed to the bottom of the rotating plate 114, and the two air outlet pipes 117 are arranged on both sides of the base 105, and the detection components are respectively connected to the first cavity 110 and the second cavity 111, and are used to measure the gas parameters in the first cavity 110 and the second cavity 111, respectively.

[0029] In this embodiment, a liquid medium is contained in the air inlet shell 108, and the mounting base is the foundation of the entire device, providing a stable support. It is made of corrosion-resistant, high-strength materials to ensure structural stability and long-term use. The outer shell 106 not only protects the internal components from the influence of the external environment, but also plays an isolation role to prevent external interference. It is connected to the base 105 by fasteners or welding to form a closed space. The air inlet pipe 107 of the air inlet assembly 102 is responsible for guiding external gas into the measuring device. When working, the gas to be measured enters the base 105 through the air inlet pipe 107. Then, the gas enters one side of the rotating plate 114 through the air inlet 118 on the base 105, and then fills the first air inlet cavity 119 or the second air inlet cavity 120. When the gas volume in the air inlet cavity is sufficient, the rotating plate 114 can be driven to rotate to drive the contact block 122 to overcome the resistance generated by the stopper 113, so that the air inlet cavity can be connected to the air outlet pipe 117 to discharge the gas. After that, the other air inlet cavity is inhaled again and drives the rotating plate 114 to rotate. In this way, the gas to be tested can be collected cyclically to ensure that the gas composition in the first cavity 110 and the second cavity 111 on both sides is consistent, avoiding the problem of inconsistent gas concentration on both sides caused by collecting a certain section of gas alone. In this way, the gas can be detected in two channels, which improves the detection efficiency.

[0030] The support assembly 101 further includes an anti-skid pad 123 , which is fixedly connected to the base 105 and located at the bottom of the base 105 .

[0031] The anti-skid pad 123 of the support assembly 101 is fixedly connected to the base 105 and is located at the bottom of the base 105. It is usually made of a high friction coefficient material such as rubber or silicone to increase the stability of the entire device and prevent sliding on a smooth surface.

[0032] The air inlet pipe 107 includes a pipe body 124 , a fixing sleeve 125 and a clamping block 126 . The fixing sleeve 125 is slidably disposed on the housing 106 . The squirrel pipe body 124 passes through the fixing sleeve 125 . The clamping block 126 is disposed on the fixing sleeve 125 .

[0033] The body 124 of the air intake pipe 107 is the main gas introduction channel, and its material must have good chemical stability and strength to cope with various gas environments. The fixing sleeve 125 is used to fix the position of the body 124. The direction or depth of the air intake pipe 107 can be fine-tuned by adjusting the position of the fixing sleeve 125 on the housing to meet different installation requirements. The clamping block 126 is set on the fixing sleeve 125, and by clamping or loosening the body 124, the air intake pipe 107 is ensured to be firm.

[0034] The base 105 includes a base body and a sealing ring 128 , and the sealing ring 128 is disposed between the base body and the air inlet shell 108 .

[0035] The seat body is the main part of the base 105, and is tightly connected to the air inlet shell 108 to ensure the integrity and air tightness of the structure. The sealing ring 128 is located between the seat body and the air inlet shell 108 to prevent gas leakage at the interface and ensure the accuracy of the measurement process.

[0036] The stopper 113 includes two triangular stoppers 129 and two supporting springs 130 . The triangular stoppers 129 are symmetrically arranged on one side of the seat body and supported by the supporting springs 130 . The contact block 122 is arranged between the two triangular stoppers 129 .

[0037] Two triangular stoppers 129 are symmetrically arranged on one side of the seat body, and their positions are maintained by support springs 130, and can be moved as needed to control the rotation direction of the rotating plate 114. The support springs 130 provide elastic force to automatically reset the triangular stoppers 129 when not in use, ensuring smooth switching of the gas channel. The contact block 122 is arranged between the two triangular stoppers 129. When the stopper 113 moves, the contact block 122 contacts a specific part on the rotating plate 114 to assist in changing the direction of gas flow.

[0038] The support shaft 115 includes a support shaft body 131, an extension rod 132 and a grip rod 133. The extension rod 132 is slidably connected to the support shaft body and passes through the housing 106. The grip rod 133 is arranged on the extension rod 132. The support shaft body 131 is a main component of the support shaft 115, bearing the weight of the rotating plate 114 and supporting its rotation. The extension rod 132 is slidably connected to the support shaft body, allowing the support shaft body to move within a certain range, so as to facilitate the adjustment of the position of the rotating plate 114. The grip rod 133 is arranged on the extension rod 132, so that the operator can manually rotate the support shaft 115, thereby controlling the direction of the rotating plate 114, so as to facilitate manual adjustment after detection to discharge the remaining gas.

[0039] The support shaft 115 further includes a sealing ring 134 , which is disposed on one side of the support shaft body 131 and the air intake housing 108 .

[0040] The sealing ring 134 is disposed between the support shaft body 131 and the air inlet shell 108 to prevent gas from leaking through the gap between the support shaft 115 and the shell, thereby maintaining the sealing of the measurement environment.

[0041] These detailed designs ensure the reliable operation of the gas measurement device in complex environments, while also improving the device's maintainability and ease of use. Through carefully designed mechanical structures and sealing measures, the device can achieve accurate gas sampling and measurement, and is suitable for scientific research, industry, environmental protection and other fields.

[0042] The detection component includes a first detector 135, a second detector 136, a data transmission unit 137 and a control unit 138. The first detector 135 is connected to the first cavity 110, the second detector 136 is connected to the second cavity 111, the data transmission unit 137 is connected to the first detector 135 and the second detector 136, and the control unit 138 is connected to the data transmission unit 137.

[0043] The first detector 135 is used to measure the gas parameters in the first cavity 110, including but not limited to temperature, pressure, humidity, gas composition (such as CO2, O2, NOx, etc.) or the concentration of other specific pollutants. The detector may contain advanced sensor technology, such as infrared spectroscopy, laser absorption spectroscopy, mass spectrometry, etc., to ensure high-precision measurement results. The second detector 136 is similar to the first detector 135, but independently measures the gas parameters in the second cavity 111. This design allows simultaneous or comparative measurement of gas samples from different sources or after different treatments, enhancing the versatility and data analysis capabilities of the device. The data transmission unit 137 receives the data signals generated by the first detector 135 and the second detector 136 and converts them into digital information. This usually involves analog-to-digital conversion (A / D conversion) to ensure that data can be effectively transmitted between electronic devices. The data transmission unit 137 may have a built-in wireless communication module (such as Bluetooth, Wi-Fi or cellular network) for remote monitoring and data recording. The control unit 138 receives information from the data transmission unit 137 and performs data processing and storage. The control unit 138 may be a microprocessor or a single-chip microcomputer, which is responsible for executing preset algorithms, such as data calibration, average value calculation, trend analysis, etc. In addition, the control unit 138 may also receive instructions through a user interface (such as a touch screen, buttons, or a remote application) to control the operating parameters of the entire device, such as sampling frequency, alarm threshold setting, etc.

[0044] The detection component integrates multiple subsystems to achieve automated and continuous monitoring of gas samples. The real-time transmission and remote access capabilities of data make the device suitable for a variety of applications, including but not limited to air quality monitoring, industrial process control, gas analysis in scientific research laboratories, and pollutant tracking in environmental protection projects. Through precise sensor technology and efficient control algorithms, the device can provide timely and reliable gas parameter information, which is of great value for decision-making and environmental management.

[0045] Second embodiment

[0046] See also Figure 7 The present invention also provides a gas measurement method, comprising:

[0047] S201 inputs the gas to be tested through the air inlet pipe 107;

[0048] At this stage, the gas to be measured is first introduced into the measuring device through the inlet pipe 107. The design of the inlet pipe 107 ensures that the gas can enter smoothly and without obstruction. At the same time, the possible filtering or pretreatment device can remove particulate matter or other impurities in the gas to prevent interference with the subsequent measurement process.

[0049] S202 The gas enters one side of the partition plate 116 through the gas inlet 118 on the base 105, so that the gas to be tested enters the first cavity 110;

[0050] When the gas passes through the gas inlet 118 on the base 105, it is directed to one side of the partition plate 116. The function of the partition plate 116 is to guide the gas to the designated first chamber 110, while preventing the gas from flowing directly into the second chamber 111 or being directly discharged without being measured. This design ensures that the gas measured each time is fresh and is not affected by the previous measurement results.

[0051] S203 When the gas in the first cavity 110 reaches the threshold, the contact block 122 located on one side of the second cavity 111 overcomes the resistance of the stopper 113 and pushes the stopper 113 downward, and the first cavity 110 rotates to the position of the gas outlet pipe 117 to discharge the gas to be tested; at this time, the second cavity 111 takes in gas;

[0052] As the amount of gas in the first cavity 110 accumulates, when the gas reaches a preset threshold, the contact block 122 located on one side of the second cavity 111 triggers the movement of the stopper 113. Under the action of the gas pressure, the contact block 122 overcomes the resistance of the stopper 113 and pushes the stopper 113 to move downward, thereby changing the flow direction of the gas.

[0053] This action causes the first cavity 110 to rotate to a position aligned with the gas outlet pipe 117, and the gas in the first cavity 110 begins to be discharged. At the same time, due to the movement of the stopper 113, the second cavity 111 begins to receive new gas to be measured, preparing for the next round of measurement.

[0054] S204: the detection component measures gas parameters in the first cavity 110 and the second cavity 111 respectively.

[0055] While the gas is being evacuated from the first cavity 110, the detection component begins to measure gas parameters in the first cavity 110. These parameters may include but are not limited to temperature, pressure, humidity, gas composition, and the like.

[0056] When the gas in the second chamber 111 accumulates to a sufficient amount, the same measurement process will be repeated in the second chamber 111. This alternating measurement mechanism ensures continuous and uninterrupted gas monitoring, and by comparing the measurement results of the two chambers, the accuracy of the measurement system can be checked and calibrated.

[0057] This gas measurement method achieves high-efficiency and high-precision gas parameter measurement through ingenious mechanical design and intelligent control logic. This method is particularly suitable for application scenarios that require continuous monitoring of gas environment changes, such as air quality monitoring, industrial process control, environmental science research and other fields.

[0058] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
