Description

Technical Field

[0001] The utility model relates to the technical field of carbon emission measurement, and particularly relates to a measuring device for carbon emissions in building construction. Background Technique

[0002] Carbon emission is a general term or abbreviation for greenhouse gas emissions. The main gas in greenhouse gases is carbon dioxide. Therefore, when describing carbon emissions, the carbon dioxide emissions are often used as a quantitative index. A carbon emission measuring device is required for carbon emission detection.

[0003] In the prior art, such as a smart city carbon emission monitoring system disclosed in CN215599118U, it includes a gas collection device, a server and a client. The gas collection device includes a sampling probe and a carbon emission analysis device arranged on the flue. The sampling probe is connected to one end of an air extraction pump through a gas transmission pipeline, and the other end of the air extraction pump is connected to the carbon emission analysis device. The carbon emission analysis device includes a gas sensor, a data processing module and a wireless transmission network module. The detection head of the gas sensor is connected to the pump body of the air extraction pump. The gas sensor is electrically connected to the data processing module, and the data processing module is electrically connected to the wireless transmission network module. The data processing module is electrically connected to the on-off valve of the air extraction pump. The wireless transmission network module is connected to the server network, and the server is also connected to the client through a wireless network. The utility model designs a collection and measurement device from the source of carbon emissions, so as to obtain accurate carbon emission monitoring data.

[0004] However, this device still has some problems. Among them, the gas discharged is directly collected at the flue outlet of carbon emissions through the sampling probe, and the carbon content of the gas in the pump body of the air extraction pump is directly detected by the gas sensor. However, when detecting carbon emissions in areas such as construction sites, due to the large amount of dust at construction sites, a large amount of dusty gas will be inhaled during sampling. These dusts may adhere to the sensors of the measuring equipment, affecting the sensitivity and accuracy of the sensors. The dust accumulated over a long time may even block the sensors, resulting in distorted measurement data and affecting the carbon emission detection problem. Therefore, we disclose a measuring device for carbon emissions in building construction to meet people's needs. Content of the Utility Model

[0005] The purpose of this application is to provide a measuring device for carbon emissions in building construction to solve the problem proposed in the above background technique that due to the large amount of dust at construction sites, a large amount of dusty gas will be inhaled during sampling. These dusts may adhere to the sensors of the measuring equipment, affecting the sensitivity and accuracy of the sensors. The dust accumulated over a long time may even block the sensors, resulting in distorted measurement data and affecting the carbon emission detection problem.

[0006] To achieve the above object, the present application provides the following technical solution: A measuring device for building construction carbon emissions, including a detection box, in which a carbon content detector is installed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-4 , the embodiments provided by the present utility model:

[0024] A measuring device for building construction carbon emissions, including a detection box 1. Inside the detection box 1, a carbon content detector 4 is installed. An air inlet is opened on one side of the detection box 1, and a purification component is installed in the air inlet. The purification component includes a filter box 2, which is installed in the air inlet. A filtering unit is installed inside the filter box 2. A delivery port is opened on the filter box 2, and a collection component is installed in the delivery port. An exhaust port is opened on one side of the detection box 1, and an exhaust pipe 10 is installed in the exhaust port.

[0025] Based on the above structure, when the device is in use, it needs to be placed at the construction site first. Align the collection component with the area to be collected. The external gas is inhaled into the filter box 2 through the collection pipe 3 by the filtering unit in the filter box 2 for filtration. The filtered gas enters the detection box 1. Through the carbon content detector 4 installed in the detection box 1, the carbon content detector 4 is a prior art, which can measure the concentration of carbon dioxide in the gas and calculate the carbon emissions. The gas after detection is then discharged through the exhaust pipe 10, avoiding dust entering the device and affecting the carbon content measurement.

[0026] As Figure 2 and 3 shown, the filtering unit includes a first fan 6, which is installed on the inner wall of the filter box 2. Two second fans 5 are installed inside the detection box 1. A detection filter screen 9 is installed in the air inlet. Through the first fan 6, the external air can be quickly inhaled into the filter box 2 from the collection pipe 3. The two second fans 5 are installed inside the detection box 1, and the negative pressure effect they generate is stronger than that of one first fan 6. The purpose is to improve the filtering rate in the filter box 2.

[0027] As Figure 2 shown, the collection unit includes a collection pipe 3, which is installed in the delivery port. A collection filter screen 8 is installed on the inner wall of the collection pipe 3. Through the collection filter screen 8, a large number of dust particles in the air at the construction site can be filtered. The filter holes are larger than the radius of the filter holes of the detection filter screen 9. The first fan 6 inhales the external gas into the filter box 2 through the collection pipe 3, and the two second fans 5 inside the detection box 1 inhale the gas in the filter box 2 into the detection box 1. The carbon content in the gas is detected by the carbon content detector 4 and displayed on the display panel 16. Through the double filtration of the collection filter screen 8 and the detection filter screen 9, the dust in the gas is filtered to prevent dust from entering the detection box 1, reducing the interference of dust on the carbon content detector 4 and improving the accuracy of the detection data.

[0028] As Figure 2As shown in the figure, a rotating rod 13 is rotatably installed on the upper side of the detection box 1. The top end of the rotating rod 13 is installed with a U-shaped block 14. An adjusting block 15 is installed on the inner wall of the U-shaped block 14 through a damping rotating shaft. A display panel 16 is installed on one side of the adjusting block 15. The display panel 16 is electrically connected to the carbon content detector 4. The data after the detection is completed will be displayed on the display panel 16, and the detection parameters of the carbon content detector 4 can also be adjusted through the display panel 16.

[0029] As Figure 2 shown in the figure, a first gas check valve 7 is installed in the sampling tube 3, and a second gas check valve 12 is installed in the exhaust pipe 10. The direction of the first gas check valve 7 is from the sampling tube 3 to the filter box 2, and the second gas check valve 12 is from the detection box 1 to the exhaust pipe 10.

[0030] As Figure 4 shown in the figure, a dust-proof cover 19 is screwed and installed at one end of the sampling tube 3, and a sealing valve 11 is installed on the exhaust pipe 10. The surface of the dust-proof cover 19 is provided with threads and can be screwed into the sampling tube 3 to achieve the effect of quick disassembly and assembly. The sealing valve 11 can cut off the connection of the exhaust pipe 10 to the outside world, ensuring that no dust enters the detection box 1. The combined action of the first gas check valve 7 and the second gas check valve 12 enables the detection box 1 to be quickly sealed after the gas collection is completed, preventing other gases from entering the detection box 1 and interfering with the measurement data. When the device is not in use, by screwing the dust-proof cover 19 onto the sampling tube 3 and closing the sealing valve 11, dust is prevented from entering the detection box 1 and affecting the next measurement, further strengthening the accuracy of the measurement data in the detection box 1.

[0031] As Figure 1 shown in the figure, a rotating block 17 is rotatably installed on the lower side of the detection box 1, and a tripod 18 is installed on the lower side of the rotating block 17. The detection box 1 can be rotated through 360 degrees by the rotating block 17. The tripod 18 is a prior art and can ensure the fixation of the detection box 1 in an area with uneven ground.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
