Description

Technical Field

[0001] This application relates to the field of environmental monitoring technology, and in particular to an atmospheric greenhouse gas measuring device. Background Technology

[0002] Greenhouse gases are atmospheric gases that absorb long-wave radiation reflected from the Earth's surface and then re-emit it, such as water vapor, carbon dioxide, and most refrigerants. Their effect is to warm the Earth's surface, similar to how a greenhouse traps solar radiation and heats the air inside. This warming effect of greenhouse gases is called the "greenhouse effect." Water vapor ,carbon dioxide nitrous oxide Freon, methane These are the main greenhouse gases in Earth's atmosphere.

[0003] Traditional atmospheric greenhouse gas measuring devices can only collect gas samples on the ground. Some devices can collect samples at a fixed altitude, but neither can achieve diversified sample collection or analyze the distribution of greenhouse gases from an altitude perspective.

The flexible component is connected to the receiving cavity and has pleats. The contact is located at the end of the flexible component. The touch switch is connected to the control valve. The sampling chamber is a vacuum chamber. The control valve controls the opening and closing of the sampling chamber. When the external pressure of the receiving cavity decreases, the gas in the receiving cavity expands, causing the pleats to unfold and drive the contact to contact the touch switch. When the touch switch contacts the contact, the control valve opens the sampling chamber.

[0009] The amount and / or type of gas stored in the containment chamber of different sampling components are different.

[0010] In one feasible implementation, the atmospheric greenhouse gas measuring device further includes:

[0011] A power source is connected to the contacts, the touch switch, and the control valve, which is configured to close the sampling chamber after opening it for a first duration.

[0012] In one feasible implementation, the atmospheric greenhouse gas measuring device further includes:

[0013] The detection assembly includes a frame and a plurality of probes, the plurality of probes being arranged at intervals on the frame, and a probe insertion port being formed on the sampling chamber of each sampling unit, the probes being used to extend into the sampling chamber through the probe insertion port.

[0014] In one feasible implementation, the sampling chamber is made of metal and has a vacuum port.

[0015] In one feasible implementation, the aircraft component includes:

[0016] The drone, wherein the connector is attached to the drone; or

[0017] A weather balloon, and the connecting member is connected to the weather balloon.

[0018] In one feasible implementation, where the aircraft assembly includes a weather balloon, the aircraft assembly further includes:

[0019] A traction rope, one end of which is connected to the aircraft component;

[0020] A mounting base is provided for fixing the device to the ground, and the other end of the traction rope is connected to the traction rope.

[0021] In one feasible implementation, the connector includes:

[0022] A connecting hole, the connecting hole including a positioning hole and an assembly hole;

[0023] Ear plates, the ear plates being arranged around the periphery of the sampling assembly;

[0024] A bolt passes through the lug connector into the mounting hole, the space of which is larger than the diameter of the mounting hole.

[0025] In one feasible implementation, a plurality of positioning grooves are formed inside the housing, and the sampling unit is detachably disposed within the positioning grooves.

[0026] In one feasible implementation, the atmospheric greenhouse gas measuring device further includes:

[0027] Memory, which stores computer programs;

[0028] The processor executes the computer program;

[0029] When the processor executes the computer program, it implements the following:

[0030] The control aircraft components drive the sampling components to rise, and the sampling components collect gas samples through the sampling chamber during the ascent.

[0031] Recover aircraft components and test samples from the sampling chamber to determine greenhouse gas concentrations;

[0032] Based on the correspondence between the sample and the collection height, a two-dimensional greenhouse gas concentration distribution map along the height direction is constructed.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] The atmospheric greenhouse gas measuring device provided in this application embodiment can, during use, use a flight component to drive a sampling component to ascend. As the sampling component ascends, the air pressure decreases, causing the gas in each containment chamber to expand due to the reduced external pressure. This expansion pushes a flexible component to deform, which in turn causes a contact point to engage with a touch switch, thereby activating a control valve. The control valve then opens the sampling chamber, allowing it to collect external air samples. Closing the control valve completes the sampling for one unit. Since the gas volume and / or type differ in the containment chambers of multiple sampling units, the activation timing of each sampling unit is different. Multiple sampling units can be activated at intervals along the altitude direction. Therefore, the atmospheric greenhouse gas measuring device provided in this application embodiment can collect air samples at different altitudes simultaneously. Afterward, the device can be recovered, and further testing can reveal the vertical distribution of greenhouse gases, significantly improving detection efficiency and providing reliable evidence of the environmental impact of greenhouse gases.

[0049] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0050] like Figures 1 to 4As shown in the embodiment of this application, an atmospheric greenhouse gas measuring device is proposed, comprising: an aircraft assembly 1, on which a connector 2 is disposed; and a sampling assembly 3, comprising a housing 307 and a plurality of sampling units disposed within the housing 307, the housing 307 being detachably connected to the connector 2; wherein each sampling unit comprises: a receiving cavity 301, a flexible member 302, a contact 303, a touch switch 304, a control valve 305, and a sampling chamber 306, the receiving cavity 301 storing gas, the flexible member 302 being connected to the receiving cavity 301, and folds being formed on the flexible member 302. The sampling chamber 306 is a vacuum chamber. The control valve 305 is used to control the opening and closing of the sampling chamber 306. When the external pressure of the receiving chamber 301 decreases, the gas in the receiving chamber 301 expands, causing the pleats to stretch and drive the contact 303 to contact the control valve 304. When the control valve 305 contacts the contact 303, the control valve 305 opens the sampling chamber 306. The amount and / or type of gas stored in the receiving chamber 301 of different sampling components 3 are different.

[0051] The atmospheric greenhouse gas measuring device provided in this application embodiment can, during use, be driven by the aircraft component 1 to rise the sampling component 3. During the ascent of the sampling component 3, as the air pressure decreases, the gas in each containment chamber 301 expands due to the decrease in external pressure. The expanding gas pushes the flexible component 302 to deform, which in turn causes the contact point 303 to contact the touch switch 304, thereby activating the control valve 305. The control valve 305 controls the opening of the sampling chamber 306, allowing the sampling chamber 306 to collect external air samples. Then, closing the control valve 305 completes the process. Sampling is completed in one sampling unit. However, the amount and / or type of gas in the containment chamber 301 of multiple sampling units are different. Therefore, the opening timing of multiple sampling units is different. Multiple sampling units can be opened at intervals along the height direction. Based on this, the atmospheric greenhouse gas measuring device provided in this application embodiment can collect air samples at different heights at one time. After that, the atmospheric greenhouse gas measuring device is recovered and further detected to know the arrangement of greenhouse gases in the height direction. This can greatly improve the detection efficiency and provide a reliable basis for the impact of greenhouse gases on the environment.

[0052] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the atmospheric greenhouse gas measuring device further includes: a power supply 4, which is connected to a contact 303, a touch switch 304, and a control valve 305, the control valve 305 being configured to open the sampling chamber 306 for a first duration and then close the sampling chamber 306.

[0053] In this technical solution, the atmospheric greenhouse gas measuring device may also include a power supply 4. The power supply 4 can power on the contact 303 and the touch switch 304. When the contact 303 and the touch switch 304 are connected, the control valve 305 can be opened. After the control valve 305 has been open for a first period of time, it can be determined that the air sample collection at that height in the sampling chamber 306 has been completed.

[0054] like Figure 4 As shown, in one feasible embodiment, the atmospheric greenhouse gas measuring device further includes a detection component 5, which includes a frame 501 and a plurality of probes 502. The plurality of probes 502 are arranged at intervals on the frame 501. A probe access port is formed on the sampling chamber 306 of each sampling unit, and the probes 502 are used to extend into the sampling chamber 306 through the probe access port.

[0055] In this technical solution, the atmospheric greenhouse gas measuring device may also include a detection component 5. The detection component 5 can detect greenhouse gases in the gas in the sampling chamber 306. The structure of the detection component 5 can be adapted to the arrangement of multiple sampling chambers 306. During the detection process, multiple probes 502 can be inserted into the probe access ports in multiple sampling chambers 306 at the same time. Based on this, the detection of samples from multiple sampling chambers 306 can be completed quickly.

[0056] It is understood that the specific structure of probe 502 can be a sensor that can be used to detect greenhouse gas content in conventional technology, and this application does not limit the specific style of probe 502.

[0057] In one feasible implementation, the sampling chamber 306 is made of metal and has a vacuum port.

[0058] In this technical solution, the sampling chamber 306 can be made of metal material, which can improve the strength of the sampling chamber 306. A vacuum port can be provided on the sampling chamber 306. After the sample is tested, the sampling chamber 306 can be evacuated by a vacuum pump and a vacuum port, so that the sampling chamber 306 can be reused.

[0059] like Figure 1 As shown, in one feasible implementation, the aircraft component 1 includes: a drone 101, and a connector 2 connected to the drone 101.

[0060] In this technical solution, the aircraft component 1 may include a drone 101, which can drive the sampling component 3 to rise or fall.

[0061] like Figure 2As shown, in one feasible embodiment, the aircraft component 1 includes a weather balloon 102, and a connector 2 is connected to the weather balloon 102.

[0062] In this technical solution, the aircraft component 1 may also include a weather balloon 102, which can also drive the sampling component 3 to rise or fall.

[0063] In one feasible implementation, when the aircraft assembly 1 includes a weather balloon 102, the aircraft assembly 1 further includes: a tow rope 6, one end of which is connected to the aircraft assembly 1; and a mounting base 7 for fixing to the ground, the other end of which is connected to the tow rope 6.

[0064] In this technical solution, when the aircraft component 1 includes a weather balloon 102, the weather balloon 102 is difficult to recover. Therefore, a towing rope 6 and a fixing seat 7 can be set. The weather balloon 102 can be fixed by the fixing seat 7. A winch can be set on the fixing seat 7 to store or release the towing rope 6.

[0065] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the connector 2 includes: a connecting hole 201, which includes a positioning hole and an assembly hole; an ear plate 202, which is arranged on the periphery of the sampling component 3; and a bolt 203, which passes through the ear plate 202 connector 2 into the assembly hole, wherein the space of the positioning hole is larger than the diameter of the assembly hole.

[0066] In this technical solution, the style of the connector 2 is further provided. The connector 2 may include a connecting hole 201. The connecting hole 201 may include a positioning hole and an assembly hole. The positioning hole and the assembly hole are opened on the aircraft component 1. The positioning hole facilitates the positioning of the bolt 203. The sampling component 3 can be fixed by passing the bolt 203 through the ear plate 202 and screwing it onto the assembly hole.

[0067] In one feasible implementation, a plurality of positioning grooves are formed inside the housing 307, and the sampling unit is detachably disposed in the positioning grooves.

[0068] In this technical solution, a housing 307 is further provided, which includes multiple positioning grooves, and the sampling unit is detachably connected to the positioning grooves, which facilitates the disassembly and installation of the sampling unit.

[0069] In one feasible implementation, the atmospheric greenhouse gas measuring device further includes: a memory storing a computer program; and a processor executing the computer program; wherein, when the processor executes the computer program, it performs the following: controls the aircraft component 1 to drive the sampling component 3 to rise, and the sampling component 3 collects gas samples through the sampling chamber 306 during the rise; recovers the aircraft component 1, detects the samples in the sampling chamber 306, and determines the greenhouse gas concentration; and constructs a two-dimensional greenhouse gas concentration distribution map in the height direction based on the correspondence between the sample and the collection height.

[0070] In this technical solution, the atmospheric greenhouse gas measuring device may further include a processor, which executes a computer program to control the ascent of the aircraft component 1 and collect multiple gas samples. After collecting multiple gas samples, the gas samples at different altitudes can be detected, thereby obtaining the point values ​​of the distribution of greenhouse gases at different altitudes. Furthermore, based on the correspondence between the greenhouse gas concentration at the altitude point values ​​and the altitude, a two-dimensional greenhouse gas concentration distribution map along the altitude direction can be constructed. Then, the greenhouse gas concentration at any altitude within a certain altitude range can be obtained through the two-dimensional greenhouse gas concentration distribution map.

[0071] In one feasible implementation, the atmospheric greenhouse gas measuring device further includes: releasing the aircraft component 1 in different regions to obtain multiple two-dimensional greenhouse gas concentration distribution maps; and obtaining a three-dimensional greenhouse gas concentration distribution map based on the multiple two-dimensional greenhouse gas concentration distribution maps.

[0072] In this technical solution, aircraft component 1 can be launched in different areas, thereby obtaining two-dimensional greenhouse gas concentration distribution maps in the corresponding altitude direction for different areas. By integrating multiple two-dimensional gas concentration distribution maps, a three-dimensional greenhouse gas concentration distribution map can be obtained. Based on this, the greenhouse gas concentration distribution status in the urban dimension can be obtained, which is particularly beneficial for studying the impact of greenhouse gas concentration on the environment.
