Description

Technical Field

[0001] This invention relates to the field of sampling device technology, and more particularly to a sampling device for carbon emission detection. Background Technology

[0002] With the advancement of global carbon neutrality goals, carbon emission monitoring of industrial enterprises has become a core component of achieving carbon emission reduction and control. Key emission-controlled industries such as thermal power, steel, and chemicals are placing higher demands on the accuracy, continuity, and convenience of carbon emission monitoring. The core prerequisite for carbon emission monitoring is obtaining representative gas samples. As a crucial piece of equipment in the monitoring process, the performance of the sampling device directly determines the reliability of the monitoring data, thereby affecting the scientific validity of carbon emission accounting, carbon footprint tracking, and carbon market regulation.

[0003] In existing devices, the sampling movement mechanism and the suction mechanism are independent, each requiring a separate drive component. Sampling movement is often achieved using a motor-driven lead screw, while suction relies on an external air pump. This approach not only increases equipment size, energy consumption, and operating noise, but also easily interferes with the testing environment. Furthermore, it leads to complex equipment structure, high failure rate, and increased maintenance costs. The air pump suction pressure is difficult to control precisely, easily causing unstable sampling flow and affecting testing accuracy. In terms of sampling range and sample representativeness, existing devices have significant limitations in their sampling methods, either using fixed-point sampling, which fails to cover different areas within the testing chamber. Sampling biases can easily arise from gradient differences in pollutant concentrations and uneven gas distribution in industrial emissions. For example, some monitoring methods show an average deviation of over 27 kg / s in CO2 emission intensity near and far from the emission source, while the deviation in the mid-range is only about 7 kg / s, highlighting the impact of sampling site selection on detection accuracy. Alternatively, they can only achieve moving sampling in a single direction, resulting in a limited sampling range and failing to guarantee sample representativeness. Furthermore, most devices can only perform single-group sampling and cannot compare multiple groups of samples, further reducing detection accuracy. Therefore, this application proposes a sampling device for carbon emission detection. Summary of the Invention

[0004] The purpose of this invention is to address the problems of low sampling accuracy, high energy consumption, cumbersome maintenance, and poor operational continuity in the prior art, and to propose a sampling device for carbon emission detection.

[0005] The technical solution of the present invention: A sampling device for carbon emission detection includes a detection box and an air inlet pipe. The air inlet pipe is fixedly installed on one side of the detection box, and an air outlet pipe is fixedly installed on the other side of the detection box.

A second track frame is fixedly installed on the bottom of the fixing block. A second slider is slidably installed on the second track frame. The second slider has a cavity. A second reciprocating screw is rotatably installed inside the second track frame. The second slider is threadedly connected to the second reciprocating screw. An air intake pipe is fixedly installed at the bottom of the block, and a filter cover is fixedly installed on the air intake pipe. Multiple equally spaced sealed cavities are fixedly installed inside the detection box. A sealing plate is slidably installed inside each sealed cavity, and a connecting block is slidably installed on the sealing plate. A second guide block with a slit surface is fixedly installed at one end of the connecting block. A first one-way valve is fixedly installed on the sealing plate, allowing only one-way air intake. A connecting pipe is fixedly installed on the first one-way valve, and the connecting pipe communicates with a second slider. Multiple second one-way valves are fixedly installed on the detection box, communicating with the sealed cavities. Each second one-way valve allows only one-way air exhaust. An air supply pipe is fixedly installed at one end of each second one-way valve, and a detection cavity is fixedly installed at one end of the air supply pipe. A detection probe is installed inside the detection cavity. A cleaning mechanism to prevent filter cover clogging is provided on the second slider.

[0006] Optionally, the cleaning mechanism includes a mounting frame fixedly installed on one side of the second slider. A turntable is rotatably mounted on the mounting frame. Multiple mounting plates arranged in a circular pattern at equal intervals are fixedly mounted on the turntable. A drain plate is slidably mounted on one side of the mounting plate. The drain plate is arc-shaped. Multiple drain blocks are fixedly mounted on the drain plate. The drain blocks are in contact with the outer wall of the filter cover.

[0007] Optionally, a fixing rod is fixedly installed inside the detection box, a flow guide cavity is fixedly installed at one end of the fixing rod, one end of the connecting pipe is connected to the flow guide cavity, a flow guide tube is fixedly installed at the bottom of the flow guide cavity, and one end of the flow guide tube is connected to the second slider.

[0008] Optionally, a detection terminal is fixedly installed on the detection box, and the detection terminal is connected to the detection probe.

[0009] Optionally, a first motor is fixedly installed on the detection box, and the output shaft of the first motor is fixedly connected to a first reciprocating lead screw.

[0010] Optionally, a second motor is fixedly installed at one end of the second track frame, and the output shaft of the second motor is fixedly connected to the second reciprocating lead screw.

[0011] Optionally, a third motor is fixedly installed at the bottom of the mounting bracket, and the output shaft of the third motor is fixedly connected to the turntable.

[0012] Optionally, a first spring is fixedly installed on the connecting block, and one end of the first spring is fixedly connected to the sealing plate.

[0013] Optionally, a second spring is fixedly installed at one end of the mounting plate, and one end of the second spring is fixedly connected to the unblocking plate.

[0014] Optionally, a third spring is fixedly installed inside the sealed cavity, and one end of the third spring is fixedly connected to the sealing plate.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention uses a first motor to drive a first reciprocating screw to rotate, which in turn drives a first slider to perform horizontal reciprocating motion on a first track frame. A faceted first guide block fixed at the top of the first slider will press against a faceted second guide block fixed to a connecting block on the sealing plate during the movement. The faceted surfaces of the two guide blocks cooperate to push the sealing plate upward within the sealing cavity, compressing the gas inside the sealing cavity and allowing it to enter the detection cavity through the second one-way valve and the gas delivery pipe. When the first guide block moves to the point of disengaging from the second guide block, the third spring inside the sealing cavity rebounds, causing the sealing plate to move downward, creating a negative pressure inside the sealing cavity. This negative pressure then draws the gas from the detection chamber into the sealing cavity through the suction pipe, the guide pipe, the guide cavity, the connecting pipe, and the first one-way valve, completing the suction action.

[0016] Furthermore, the first motor drives the first reciprocating screw, causing the first slider and the second track frame at the bottom to perform horizontal reciprocating motion (first dimension); the second motor drives the second reciprocating screw, causing the second slider to perform lateral reciprocating motion on the second track frame (second dimension), thereby causing the suction pipe and filter cover to achieve bidirectional reciprocating movement of "horizontal + lateral", which can fully cover the internal space of the detection chamber, ensuring that the sampled sample can cover the gas in different areas of the detection chamber, avoiding sampling deviation caused by uneven gas distribution. In conjunction with multiple equally spaced sealed chambers in the detection chamber, multiple sets of samples can be collected and transported simultaneously. Each sealed chamber is equipped with an independent sealing plate, a first one-way valve, and a connecting pipe, and is connected to the guide chamber. The gas drawn in by the suction pipe is diverted to each connecting pipe through the guide chamber, and then enters the corresponding sealed chamber through the first one-way valve, and finally is transported to the detection chamber through the second one-way valve and the gas delivery pipe, realizing the simultaneous detection of multiple sets of samples.

[0017] Furthermore, a third motor drives the turntable to rotate. Multiple mounting plates arranged in a circular pattern at equal intervals are fixed on the turntable. An arc-shaped unblocking plate is slidably installed on one side of the mounting plate. Multiple unblocking blocks are fixed on the unblocking plate, and the unblocking blocks are in close contact with the outer wall of the filter cover. When the turntable rotates, it drives the mounting plate and the unblocking plate to rotate synchronously. The unblocking blocks rub against the outer wall of the filter cover, removing impurities attached to the surface of the filter cover in real time and preventing the filter cover from becoming clogged.

[0018] This invention enables multi-directional, high-purity gas sampling and automated detection, improving detection accuracy, operational continuity, and reducing energy consumption and maintenance costs. Attached Figure Description

[0027] Example 1 like Figure 1-7As shown, the present invention proposes a sampling device for carbon emission detection, including a detection box 1 and an air inlet pipe 2. The air inlet pipe 2 is fixedly installed on one side of the detection box 1, and an air outlet pipe 3 is fixedly installed on the other side of the detection box 1. A first track frame 5 is fixedly installed inside the detection box 1, and a first slider 6 is slidably installed on the first track frame 5. A first reciprocating screw 7 is rotatably installed inside the first track frame 5, and the first slider 6 is threadedly connected to the first reciprocating screw 7. A first guide block 18 is fixedly installed on the top of the first slider 6, and the first guide block 18 is slit-faceted. A fixing block 8 is fixedly installed on the bottom of the first slider 6, and a second track frame 9 is fixedly installed on the bottom of the fixing block 8. A second slider 12 is slidably installed on the second track frame 9. For the cavity design, a second reciprocating screw 13 is rotatably installed inside the second track frame 9. The second slider 12 is threadedly connected to the second reciprocating screw 13. An air intake pipe 15 is fixedly installed at the bottom of the second slider 12, and a filter cover 14 is fixedly installed on the air intake pipe 15 to prevent dust and debris from entering the air intake pipe 15. Multiple equally spaced sealed cavities 16 are fixedly installed inside the detection box 1. A sealing plate 22 is slidably installed inside the sealed cavity 16. A connecting block 20 is slidably installed on the sealing plate 22. A second guide block 19 is fixedly installed at one end of the connecting block 20. The second guide block 19 is slit-faceted. A first one-way valve 23 is fixedly installed on the sealing plate 22. The first one-way valve 23 can only allow air to enter in one direction. A connecting pipe 24 is fixedly installed on the first one-way valve 23. The connecting pipe 24 is connected to... The second slider 12 is connected. Multiple second one-way valves 25 are fixedly installed on the detection box 1. Each second one-way valve 25 is connected to the sealing cavity 16 and can only discharge gas in one direction. A gas supply pipe 26 is fixedly installed at one end of the second one-way valve 25, and a detection cavity 17 is fixedly installed at the other end of the gas supply pipe 26. A detection probe is installed inside the detection cavity 17. When it is necessary to sample and detect the gas inside the detection box 1, the first reciprocating screw 7 and the second reciprocating screw 13 are rotated. The first reciprocating screw 7 drives the first slider 6 to perform horizontal reciprocating motion on the first track frame 5. The first slider 6 drives the second track frame 9 to move together, coordinating with the second reciprocating screw 13 to drive the second slider 12 to reciprocate on the second track frame 9. The second slider 12 drives the bottom suction valve. The suction pipe 15 moves together, allowing it to continuously change position within the detection chamber 1. When the first slider 6 moves, the first guide block 18 at the top of the first slider 6 presses against the cross-section of the second guide block 19, causing the second guide block 19 to move the sealing plate 22 upward. The sealing plate 22 forces the gas in the sealing cavity 16 into the second one-way valve 25 for discharge. As the first guide block 18 loses contact with the second guide block 19 during its movement, the third spring 37 rebounds, causing the sealing plate 22 to move downward. At this time, the air pressure in the sealing cavity 16 decreases, and the gas in the detection chamber 1 is drawn from the suction pipe 15 into the connecting pipe 24, and finally delivered to the sealing cavity 16 by the first one-way valve 23. As the first slider 6 and the second slider 12 continue to move...The suction tube 15 draws gas from multiple directions within the detection chamber 1 into the sealed cavity 16, and finally delivers it into the detection cavity 17. The detection probe detects the carbon content of the gas in the detection cavity 17, improving the diversity and accuracy of the detection. Multiple equally spaced sealed cavities 16 enable simultaneous collection and delivery of multiple samples, further enhancing the comprehensiveness of the sampling and solving the core problems of insufficient sample representativeness and large detection bias in carbon emission detection. The coordinated design of the first one-way valve 23 and the second one-way valve 25 in the sealed cavity 16 effectively prevents backflow of the sampled gas within the sealed cavity 16, avoiding gas mixing between different areas and ensuring that the sample collected in each sealed cavity 16 is pure gas from the corresponding location, reducing cross-contamination. The second slider 12 is equipped with a cleaning mechanism to prevent clogging of the filter cover 14.

[0028] Example 2 like Figure 2-9 As shown, the cleaning mechanism includes a mounting bracket 36 fixedly installed on one side of the second slider 12. A turntable 35 is rotatably mounted on the mounting bracket 36. Multiple mounting plates 31 arranged in a circular pattern at equal intervals are fixedly mounted on the turntable 35. A drain plate 33 is slidably mounted on one side of the mounting plate 31. The drain plate 33 is arc-shaped and multiple drain blocks 34 are fixedly mounted on the drain plate 33. The drain blocks 34 contact the outer wall of the filter cover 14. When the turntable 35 is rotated, the turntable 35 drives the mounting plate 31 to rotate. The drain blocks 34 on the drain plate 33 continuously rub against the outer wall of the filter cover 14 to remove impurities attached to the surface of the filter cover 14 and prevent dust from clogging the filter cover 14 and affecting the air intake effect.

[0029] Example 3 like Figure 4-8 As shown, a fixed rod 28 is fixedly installed inside the detection box 1. A guide cavity 27 is fixedly installed at one end of the fixed rod 28. One end of the connecting pipe 24 is connected to the guide cavity 27. A guide pipe 29 is fixedly installed at the bottom of the guide cavity 27. One end of the guide pipe 29 is connected to the second slider 12. A detection terminal 4 is fixedly installed on the detection box 1. The detection terminal 4 is connected to the detection probe and analyzes the data from the detection probe. A first motor 10 is fixedly installed on the detection box 1. The output shaft of the first motor 10 is fixedly connected to the first reciprocating lead screw 7. One end of the second track frame 9 is fixed... A second motor 11 is installed, and the output shaft of the second motor 11 is fixedly connected to the second reciprocating lead screw 13. A third motor 30 is fixedly installed at the bottom of the mounting bracket 36, and the output shaft of the third motor 30 is fixedly connected to the turntable 35. A first spring 21 is fixedly installed on the connecting block 20, and one end of the first spring 21 is fixedly connected to the sealing plate 22. A second spring 32 is fixedly installed at one end of the mounting plate 31, and one end of the second spring 32 is fixedly connected to the unblocking plate 33. A third spring 37 is fixedly installed in the sealing cavity 16, and one end of the third spring 37 is fixedly connected to the sealing plate 22.

[0030] Working principle: When it is necessary to sample and test the gas in the detection chamber 1, the first reciprocating screw 7 and the second reciprocating screw 13 are rotated. The first reciprocating screw 7 drives the first slider 6 to move horizontally back and forth on the first track frame 5. The first slider 6 drives the second track frame 9 to move together. In conjunction with the second reciprocating screw 13, the second slider 12 drives the second slider 12 to move back and forth on the second track frame 9. The second slider 12 drives the bottom suction pipe 15 to move together. When the first slider 6 moves, the first guide block 18 at the top of the first slider 6 squeezes the cut surface of the second guide block 19, causing the second guide block 19 to drive the sealing plate 22 to move upward. The sealing plate 22 squeezes the gas in the sealing cavity 16 into the second one-way valve 25 for discharge. As the first guide block 18 moves, it disconnects from the second guide block 25. When block 19 contacts, the third spring 37 rebounds and drives the sealing plate 22 to move downward. At this time, the air pressure in the sealing cavity 16 decreases, and the gas in the detection box 1 is drawn into the connecting pipe 24 from the suction pipe 15. Finally, it is delivered into the sealing cavity 16 by the first one-way valve 23. As the first slider 6 and the second slider 12 move continuously, the suction pipe 15 can draw gas from multiple directions in the detection box 1 into the sealing cavity 16 and finally deliver it into the detection cavity 17. The detection probe detects the carbon content of the gas in the detection cavity 17, improving the diversity and accuracy of the detection. The turntable 35 is rotated, and the turntable 35 drives the mounting plate 31 to rotate. The unblocking block 34 on the unblocking plate 33 continuously rubs against the outer wall of the filter cover 14 to remove impurities attached to the surface of the filter cover 14 and prevent dust from clogging the filter cover 14 and affecting the air intake effect.

[0031] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
