Description

Technical Field

[0001] This utility model relates to the field of carbon emission monitoring, and in particular to a carbon emission monitoring device. Background Technology

[0002] Carbon emission monitoring at construction sites refers to the monitoring of greenhouse gas emissions such as carbon dioxide generated during construction processes or activities. Carbon emission monitoring and analysis often rely on gas analyzers. For high-speed railway bridge construction, cantilever construction using hanging baskets is common, with the cast-in-place box girder located below the cantilever. However, existing carbon emission monitoring devices are generally horizontal structures, requiring placement on the cantilever or the already cast bridge deck, making it difficult to effectively collect air samples from the cast-in-place box girder area for carbon emission monitoring. In other words, existing on-site carbon emission monitoring devices are prone to limitations in the collection area and inaccurate monitoring results when using hanging basket cantilever construction. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of limited data collection area and inaccurate monitoring results in existing carbon emission monitoring devices when facing cantilever construction operations, and to provide a carbon emission monitoring device.

[0004] In a first aspect, the present invention provides a carbon emission monitoring device, including a gas analyzer, a positioning tube being snapped into the lower part of the gas analyzer, a horizontal pipe section being connected to one end of the positioning tube, and a vertical pipe section being connected to one end of the horizontal pipe section. The horizontal pipe section and the vertical pipe section together form an L-shaped pipe; The positioning tube is connected to the horizontal pipe section, and the horizontal pipe section is connected to the vertical pipe section; The end of the vertical pipe section furthest from the horizontal pipe section is open.

[0005] To address the limitations of existing carbon emission monitoring techniques during cantilever construction, which suffer from restricted data collection areas and inaccurate results, this invention proposes a carbon emission monitoring device. This device connects a gas analyzer to a positioning tube. The open end of the positioning tube is connected to the transverse section of an L-shaped tube, which extends vertically downwards. In practical use, the L-shaped tube is inverted and placed on the end of the cantilever or the already poured bridge deck, with the vertical section extending downwards and its bottom open. At this point, the positioning tube, gas analyzer, and transverse section are all placed flat on the cantilever or the already poured bridge deck. When the box girder is poured, the carbon-containing gas released sequentially enters the vertical section, the transverse section, and the positioning tube, ultimately passing through the positioning tube into the gas analyzer. Furthermore, the weight of this application is largely provided by the gas analyzer, which is located on the positioning tube. This effectively shifts the center of gravity of the application towards the rear, i.e., towards the direction of the gas analyzer, thereby improving the stability of the application and preventing it from falling into the pouring area below and interfering with normal construction operations. Although this application is installed on a cantilever or a poured bridge deck, it can collect gas and monitor carbon emissions in the box girder pouring area, overcoming the problems of limited collection area and inaccurate monitoring results in the prior art. This improves the effectiveness of the collection area and also helps to improve the accuracy of the monitoring results.

[0006] This invention provides a carbon emission monitoring device that can collect gas and monitor carbon emissions in the box girder casting area. It overcomes the problems of limited collection area and inaccurate monitoring results in the prior art, improves the effectiveness of the collection area, and also helps to improve the accuracy of monitoring results.

[0007] Preferably, the gas analyzer is equipped with a concentration sensor, which is used to monitor the concentration of carbon dioxide; The gas analyzer is also equipped with a one-way valve on top.

[0008] By installing a concentration sensor inside the gas analyzer, carbon dioxide concentration can be monitored in real time and accurately, providing reliable data support for gas environment detection. A one-way valve on the top of the gas analyzer ensures that the gas being detected flows in one direction, preventing backflow of external air from affecting the sensor's detection accuracy, thereby improving the stability and reliability of the gas analyzer.

[0009] Preferably, the side of the positioning tube facing the gas analyzer is provided with a connecting pipe, and the side of the gas analyzer facing the positioning tube is provided with a slot, through which the gas analyzer is connected to the connecting pipe.

[0010] By setting a connecting pipe on the positioning tube and a slot on the gas analyzer, the two can be reliably connected, ensuring that the gas can smoothly enter the gas analyzer for detection. This avoids gas leakage or detection errors caused by unstable interfaces, thereby improving the accuracy of gas analysis and the overall sealing and reliability of the device.

[0011] Preferably, the positioning tube has a first positioning part at one end facing the transverse tube segment, and the transverse tube segment has a second positioning part at one end facing the positioning tube, wherein the first positioning part and the second positioning part are engaged.

[0012] By setting a first positioning part and a second positioning part at the opposite end of the positioning tube and the transverse tube section respectively, and connecting them by snap-fit, it is possible to achieve rapid assembly and reliable positioning between the two, avoiding the problems of complex installation and difficult disassembly caused by traditional threaded or welded connection methods.

[0013] Preferably, the first positioning part is provided with a first positioning hole, and the second positioning part is provided with a second positioning hole that matches the first positioning hole, and the first positioning hole and the second positioning hole are connected by bolts.

[0014] By setting positioning holes in the first and second positioning parts respectively and connecting them with bolts, the fixing strength between the positioning tube and the transverse tube section can be further enhanced, preventing loosening or displacement during use. At the same time, this connection method has a simple structure and is easy to assemble and disassemble, which not only ensures the stability and sealing of the connection, but also facilitates later maintenance and replacement, thereby improving the reliability and practicality of the device.

[0015] Preferably, a filtration device is provided in the horizontal pipe section and / or the vertical pipe section.

[0016] By installing filtration devices in the horizontal and / or vertical pipe sections, the gas entering the gas analyzer can be pre-treated to effectively remove impurity particles or water vapor, thus avoiding their impact on the detection accuracy and service life of the concentration sensor. This improves the accuracy and stability of gas analysis and extends the service life of the equipment.

[0017] Preferably, the positioning tube is equipped with a drying device.

[0018] By installing a drying device inside the positioning tube, the gas entering the gas analyzer can be dehumidified, effectively reducing the interference of water vapor on the concentration sensor, avoiding detection errors or component damage caused by a humid environment, thereby improving the accuracy of gas detection results and the reliability of equipment operation.

[0019] Preferably, the drying device includes a first grid plate located inside the positioning tube, and the drying device further includes a second grid plate detachably connected to the inner wall of the positioning tube.

[0020] By setting a first grid plate inside the positioning tube and a second grid plate that is detachably connected to the inner wall, the installation and disassembly of the drying device can be facilitated, and the drying material can be easily replaced or cleaned later. At the same time, the double-layer grid plate structure can effectively limit and support the drying material, preventing the drying material from shifting or becoming blocked during gas flow, thereby ensuring smooth gas flow and maintaining the drying effect, and improving the detection stability and service life of the gas analyzer.

[0021] Preferably, a desiccant is filled between the first grid plate and the second grid plate.

[0022] By filling the space between the first and second grid plates with desiccant, the moisture in the incoming gas can be effectively adsorbed, further reducing the gas humidity and preventing water vapor from affecting the detection accuracy of the concentration sensor and electronic components. This ensures the accuracy of gas detection, improves the reliability of the equipment, and extends the service life of the sensor and the entire machine.

[0023] Preferably, the end of the positioning tube facing the transverse tube section is provided with an annular positioning groove, and the end of the second grid plate facing the positioning tube is provided with a snap-fit ​​part, and the annular positioning groove is connected to the snap-fit ​​part.
