[0002] "Green carbon" generally refers to the process of absorbing and storing carbon dioxide (carbon sink) through green land (such as forests, grasslands, wetlands and other natural or artificial ecosystems), thereby reducing the concentration of greenhouse gases in the atmosphere and helping to combat climate change.

[0003] Green carbon sampling is usually used for air collection in towns and parks. The air quality in towns is relatively high due to their distance from cities. However, due to different lifestyles in each town, such as the presence of many processing plants, the overall air quality in the town is reduced, and there is a large amount of dust and carbon dioxide in the air, which in turn reduces the normal oxygen standard for the town's population. Existing air collectors usually use carbon dioxide sensors to measure the carbon dioxide content in the air. For towns with many processing plants, the air often contains visible impurities such as willow catkins, willow catkins, and broken leaves. If these impurities are not filtered out before collection, it will not only affect the accuracy of carbon content collection, but also cause pollution to the internal structure of the device, thereby affecting the service life.

[0004] Therefore, we designed a kind of urban green space carbon reserve sampling equipment based on field sampling. INVENTION CONTENTS

Specific implementation

[0025] The technical scheme in the utility model embodiment will be described in detail below with reference to the drawings.

[0026] Reference Figures 1-6 , a kind of based on field sampling urban green carbon storage sampling equipment, including box body 1 and being set in box body 1 inside for transferring air main pipe 2, still include filter assembly, filter assembly includes with main pipe 2 tail end communication filter body 3, be arranged in filter body 3 inside and be annular arrangement flow guide vane 302, be arranged in filter body 3 inside and be linear arrangement impurity filter screen 303 and be arranged in filter body 3 top for gas conveying and move group component;

[0027] It needs to be explained that, since urban green environment is different, staff needs to place the device as a whole in each area of town, to facilitate detecting whether the carbon dioxide content of each area reaches the standard, box body 1 is made of wooden material or stainless steel material as a whole, mainly selects portable material to make, improve the portability of box body 1, since box body 1 is mainly used for storing sampling assembly, main pipe 2 in its interior is the main pipeline for carbon dioxide collection, is made of PC material as a whole, and is three-way conduit in prior art, in order to improve the observation state of the internal structure of box body 1, box body 1 is closed around by acrylic plate, and a hole is formed in advance in the side wall of box body 1, when staff selects sampling site, emptying pipe 307 can be installed on box body 1;Since the air collector of prior art is relatively flat, it does not have air filtering component inside, filter assembly can effectively improve the carbon dioxide quality collected by the sampling equipment, while avoiding the influence of visible impurities such as willow catkins, willow catkins, broken leaves on the smooth performance of main pipe 2;

[0028] The filter body 3 is in the shape of a cylindrical tube, and its top end is connected to the tail end of the main pipe 2, and the filter body 3 is the only way for the gas to flow to the exhaust pipe 307. In order to improve the removal effect of visible impurities such as plant debris in the gas, the guide fan blade 302 can guide the air to flow into the filter body, wherein the guide fan blade 302 is fixed in the filter body 3 by a fastener, and the impurity filter screen 303 is a mesh structure in the prior art and is arranged in the filter body 3 to intercept visible impurities such as plant debris. In addition, in order to improve the air flow, the filter body 3 can be quickly sampled by the pumping assembly.

[0029] The pumping assembly includes an exhaust pipe 307 arranged at the top of the filter body 3 through a conveying pipe 301, a gas pump 304 fixedly arranged on the side wall of the conveying pipe 301, a hose 305 symmetrically arranged on the side wall of the gas pump 304 and communicated with the conveying pipe 301, and an adjusting assembly arranged on the conveying pipe 301. Further, the adjusting assembly includes an adjusting valve 306 arranged at the connection between the exhaust pipe 307 and the conveying pipe 301, and the exhaust pipe 307 is fixedly connected with the conveying pipe 301.

[0030] It should be noted that, in order to facilitate real-time detection of the carbon dioxide content in the air discharged from the filter body 3, a carbon dioxide content sensor is arranged on the inner wall of the conveying pipe 301, so that the carbon dioxide content in the air passing through the sensor can be collected in real time.

[0031] In use, when the staff needs to collect carbon dioxide in the current area, first ensure that the conveying pipe 301 installed at the top of the filter body 3 is connected with the exhaust pipe 307, and then start the gas pump 304 suspended on the outer wall of the conveying pipe 301 to work. The gas pump 304 is a pump body component for extracting gas in the prior art, and the gas pump 304 can be fixed on the outer wall of the conveying pipe 301 by a fastener. In order to improve the output capacity of the gas pump 304, the hoses 305 on both sides of the gas pump 304 can improve the efficiency of carbon dioxide entering the filter body. In order to avoid the air passing through the filter body 3 too quickly and affecting the collection quality of carbon dioxide, the adjusting valve 306 is rotated to reduce the air passing space in the conveying pipe 301, and the flow rate of the gas passing through the filter body 3 is reduced.

[0032] It should be noted that the staff needs to drive the gas pump 304 by an external power source, and when it is necessary to improve the carbon dioxide collection quality, it is only necessary to rotate the adjusting valve 306 to increase the flow rate of the gas flowing into the filter body 3.

[0033] The main pipe 2 is also provided with a sampling assembly, which comprises a first sampling pipe 201 fixedly installed at the bottom end of the main pipe 2 and a second sampling pipe 202 fixedly installed at the side wall of the main pipe 2, and the first sampling pipe 201 and the second sampling pipe 202 are both made of PC material, and the main pipe 2 is also provided with a stabilizing assembly, which comprises a fixed body 203 arranged at the side wall of the main pipe 2, a first damping spring 204 vertically arranged at the bottom of the fixed body 203 and a second damping spring 205 arranged at the bottom of the second sampling pipe 202.

[0034] In use, when the staff decides to perform sampling work, the first sampling pipe 201 and the second sampling pipe 202 need to be fixed at the bottom and the side wall of the main pipe 2 respectively, and the waterproof rubber is wound at the connection to increase the connection strength and reduce the risk of gas leakage. The staff is easy to cause the main pipe 2 to deviate when lifting the box body 1, and since the first sampling pipe 201 and the second sampling pipe 202 are fixed on the main pipe 2, the main pipe 2 needs the stabilizing assembly inside the box body 1 to improve the stability, so the fixed body 203 is fixed at one end of the main pipe 2 away from the second sampling pipe 202, and the first damping spring 204 fixedly installed at the bottom of the fixed body 203 plays the role of elastically connecting the fixed body 203 and the box body 1, reducing the deviation of the main pipe 2 caused by the shaking of the box body 1, and further reducing the risk of displacement of the main pipe 2 caused by the first sampling pipe 201 penetrating the filter body too deeply. Similarly, in order to meet the stable support effect of the second sampling pipe 202 arranged on the other side of the main pipe 2, the second damping spring 205 arranged at the bottom of the second sampling pipe 202 can have the same effect as the first damping spring 204.

[0035] It should be noted that after the first sampling pipe 201 and the second sampling pipe 202 are installed, they need to be connected with the stabilizing assembly to avoid deviation and misalignment of the main pipe 2, and the stabilizing assembly can reduce the vibration of the first sampling pipe 201 and the second sampling pipe 202 caused by the operation of the air pump 304 during sampling.

[0036] The side wall of the main pipe 2 is fixedly installed with an operation display screen 206, the top of the main pipe 2 is fixedly installed with a pressure gauge 208, and the bottom of the box body 1 is provided with a bottom ring 207. Since the main pipe 2 is inside the box body 1, the staff cannot know the real-time data according to observation, so an operation display screen 206 needs to be fixedly installed outside the box body 1, so that the staff can monitor in real time during sampling work, and the staff can observe the internal air pressure through the pressure gauge 208 at the top of the main pipe 2, which can effectively avoid the phenomenon of gas leakage caused by too high air pressure. When the staff finds that the first sampling pipe 201 exposed outside the box body 1 deviates or shakes obviously, the bottom ring 207 can be fixed at the bottom of the box body 1 to increase the stability and limiting effect of the first sampling pipe 201 inside the box body 1.

[0037] The box 1 is rotationally connected with a cover 4 at the top, and symmetrically provided with a hanging end 5 on the side wall, so that after the staff member observes the pressure displayed by the pressure gauge 208 on the top of the main pipe 2, the box 1 can be closed as a whole by closing the cover 4, and the staff member can fix the sampling device in the planned area through the hanging end 5 before sampling, so as to ensure the effective sampling range of the first sampling pipe 201 and the second sampling pipe 202.

[0038] The working principle of the utility model is as follows:

[0039] The staff member transports the box 1 to the sampling site determined in advance, then fixes the box 1 in the sampling area through the hanging tool, ensures that the bottom and the side wall of the box 1 have sampling space, then starts the air pump 304 to make the hoses 305 on both sides produce the pumping effect, the gas around the box 1 enters the main pipe 2 from the first sampling pipe 201 and the second sampling pipe 202, under the driving of the air pump 304 and the guiding action of the guide fan blade 302, the gas enters the filter body 3, at this time, the visible impurities such as willow catkins, poplar catkins and plant debris carried in the gas are blocked by the impurity filter screen 303 in the filter body 3, then enter the emptying pipe 307 through the conveying pipe 301, at this time, the carbon dioxide content sensor in the conveying pipe 301 can be used to detect the air passing through, compared with the prior art, not only the collection accuracy of carbon dioxide is improved, but also the service life of the device can be avoided from being affected by too many visible impurities.
