Description

Technical Field

[0001] This invention relates to the field of carbon emission detection technology, and in particular to a device and method for detecting the energy-saving and carbon-reduction effects of buildings. Background Technology

[0002] As one of the major sectors of carbon emissions, the construction industry's energy conservation and emission reduction efforts are particularly important. In the construction industry, the generation and treatment of construction waste is one of the important sources of carbon emissions. Building energy conservation and carbon reduction effect testing devices are special equipment or systems used to evaluate the energy consumption and carbon emission levels of buildings during operation. Their core purpose is to quantify the energy conservation and carbon reduction effectiveness of buildings through scientific and accurate testing methods, and to provide data support for optimizing building energy efficiency and formulating emission reduction strategies.

[0003] When monitoring carbon emissions from construction waste, detection equipment must be deployed at designated monitoring points to collect gas samples and determine concentrations. Due to the gas dynamics within the monitoring space, differences in airflow rates and gas stratification exist at different vertical gradients, resulting in a heterogeneous distribution of carbon dioxide concentrations at various height levels. This three-dimensional gas concentration gradient can easily lead to systematic biases in the measurement results. Furthermore, when conventional gas sampling pumps introduce samples using negative pressure extraction, the high concentration of suspended particulate matter in the air can easily cause filter clogging during continuous operation, obstructing the gas transmission channel and ultimately reducing the sampling efficiency of the detection system and interfering with the accuracy and stability of the monitoring data. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a device and method for detecting the energy-saving and carbon-reduction effects of buildings. This device enables continuous and balanced collection of gas samples from multiple directions, comprehensively reflecting the carbon emission distribution around the building. Simultaneously, a fixed brush remains in close contact with the rotating filter screen, continuously scraping away dust and foreign matter adhering to the filter screen, preventing pore blockage and maintaining stable air permeability.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, a building energy-saving and carbon-reduction effect testing device includes an air supply pipe, one end of which is connected to a carbon emission detector via a pump body, and the other end is connected to a connecting housing. A rotatable connecting sleeve is provided on one side of the connecting housing and is interconnected with each other. The sleeve is connected to an air intake plate via several first connecting pipes. A filter screen is provided on the front side of the air intake plate. The connecting housing is equipped with a fixed brush via a rod. The fixed brush and the filter screen are on the same vertical plane. The connecting housing is also equipped with a driving mechanism. The output end of the driving mechanism can drive the sleeve to rotate so that the fixed brush can clean the filter screens on different air intake plates.

[0006] As a further implementation, the bottom of the carbon emission detector is connected to a filter box via an exhaust pipe, and the filter box is equipped with an exhaust pipe.

[0007] As a further implementation, the top end of the gas supply pipe is connected to the connecting housing, one end of the sleeve is rotatably connected to the front side of the connecting housing, the output end of the drive mechanism is provided with a first gear, and the circumference of the sleeve is provided with a second gear. The first gear and the second gear mesh to realize the rotation of the sleeve.

[0008] As a further implementation, the first connecting tube is an L-shaped rod, and several first connecting tubes are evenly distributed around the sleeve. The rod has a rectangular frame structure, and the fixing brush is vertically fixed on the rod.

[0009] As a further implementation, the carbon emission detector is equipped with a wind speed detection component and a wind direction detection component on its outer side.

[0010] As a further implementation, the carbon emission detector has a display screen on one side, and guide rods and rotatable first threaded rods are respectively set on the upper and lower sides of the display screen. The guide rods and the first threaded rods are connected by a cleaning brush. One end of the first threaded rod is connected to a driving component, and the driving component drives the first threaded rod to rotate so that the cleaning brush can clean the display screen.

[0011] As a further implementation, the filter box is supported by a telescopic rod, the bottom end of which is fixed to a fixed plate.

[0012] As a further implementation, the telescopic rod includes a first connecting rod and a second connecting rod. The bottom end of the second connecting rod is connected to a fixed plate, and the top end is sleeved on the first connecting rod. The top end of the first connecting rod is fixed to the filter box. The first connecting rod extends and retracts relative to the second connecting rod to adjust the height of the filter box.

[0013] As a further implementation, the second connecting rod is provided with a worm gear mechanism. The worm is located on the second connecting rod, and the worm wheel is located inside the second connecting rod and fixed to the periphery of the second threaded rod. Rotating the worm causes the worm wheel to drive the second threaded rod to rotate. The second threaded rod extends into the first connecting rod and cooperates with the slider. The slider is fixed to the inside of the first connecting rod. Rotating the first threaded rod causes the slider to drive the first connecting rod to rise and fall.

[0014] Secondly, a method for operating a building energy conservation and carbon reduction effect testing device, using any of the above-described building energy conservation and carbon reduction effect testing devices, includes the following steps: Under the action of the pump, the gas enters the carbon emission detector through the air intake plate. The carbon emission detector detects the carbon dioxide concentration and greenhouse gas components in the gas in real time. The gas passes through the filter screen of the air intake plate, which intercepts particulate matter and impurities in the air. The drive mechanism drives the sleeve to rotate around the connecting housing as the axis, which drives the first connecting pipe and the air intake plate fixed on it to rotate synchronously. This allows multiple air intake plates to periodically switch sampling positions to achieve multi-angle gas collection. At the same time, the fixed brush is in close contact with the rotating filter screen surface to continuously scrape off the dust and foreign objects attached to the filter screen.

[0015] The beneficial effects of the present invention are as follows: 1. This detection device can drive the sleeve to rotate, causing the evenly distributed air intake disc to perform 360° spatial rotation sampling, achieving continuous and balanced collection of gas samples from multiple directions, comprehensively reflecting the carbon emission distribution around the building. Simultaneously, during the sleeve's rotation, the fixed brush remains in close contact with the rotating filter surface, continuously scraping away dust and foreign matter adhering to the filter, preventing pore blockage, maintaining stable air permeability of the filter, and ensuring continuous airflow. This provides clean and stable gas samples for subsequent carbon emission detection, effectively guaranteeing the accuracy of the detection data.

[0016] 2. This invention utilizes a cleaning brush to fully cover the display screen of the carbon emission detector, effectively removing dust, water stains, or dirt adhering to the screen and ensuring clear display of the test data. This design avoids the inconvenience of manual cleaning and potential damage to the equipment, improves data visibility, and also ensures stable operation of the equipment in various environments, extending its service life.

[0017] 3. The gas detected by this invention is discharged from the exhaust pipe and enters the filter box for multi-layer purification media treatment to adsorb residual pollutants or harmful substances. It is then discharged to the external environment through the exhaust pipe, forming a closed loop to achieve harmless treatment of the detection waste gas and reduce the impact of the discharged gas on the environment.

[0018] 4. The present invention controls the first connecting rod to slide up and down within the second connecting rod via a worm gear, thereby adjusting the vertical distance between the filter box and the fixed plate, enabling the device to adapt to different installation environments and improving the versatility and practicality of the device.

[0019] 5. The wind speed detection component and wind direction detection component of the present invention monitor airflow speed and wind direction data in real time and feed them back to the detector, dynamically correcting the gas sampling efficiency, thereby further improving the adaptability and detection accuracy of the detection device in different environments.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] Example 1 In a typical embodiment of the present invention, reference is made to Figures 1-6As shown, a building energy-saving and carbon-reduction effect testing device includes an air supply pipe 1, one end of which is connected to a carbon emission detector 2 via a pump body 10, and the other end is connected to a connecting housing 3. A rotatable connecting sleeve 4 is connected to one side of the connecting housing 3 and is interconnected with each other. The sleeve 4 is connected to an air intake plate 6 via several first connecting pipes 5 around its periphery. A filter screen 7 is provided on the front side of the air intake plate 6. The connecting housing 3 is equipped with a fixed brush 8 via a rod 9. The fixed brush 8 and the filter screen 7 are on the same vertical plane. The connecting housing 3 is also equipped with a driving mechanism. The output end of the driving mechanism can drive the sleeve 4 to rotate so that the fixed brush 8 can clean the filter screen 7 on different air intake plates 6.

[0026] like Figure 2 and Figure 3 As shown, the bottom end of the gas transmission pipe 1 is connected to the carbon emission detector 2 through the pump body 10, and the top end is connected to the rear side wall of the connecting housing 3. The front side of the connecting housing 3 is rotatably engaged with one end of the sleeve 4 and connected to each other. One end of the first connecting pipe 5 is fixedly connected to the periphery of the sleeve 4, and the other end of the first connecting pipe 5 is fixedly connected to the air intake plate 6. A filter screen 7 is fixedly installed on the front side of the air intake plate 6.

[0027] The working principle of the energy-saving and carbon-reduction effect testing device for buildings proposed in this invention is as follows: After the pump body 10 is started, a negative pressure airflow is formed in the air supply pipe 1, and external air is drawn in through the opening of the air inlet plate 6. The gas first passes through the filter screen 7 fixed to the air inlet plate 6, which intercepts particulate matter and impurities in the air, ensuring that the gas entering the system is clean. At the same time, the sleeve 4 rotates around the connecting housing 3 as the axis, driving the first connecting pipe 5 fixed thereon and the air inlet plate 6 to rotate synchronously, so that multiple air inlet plates 6 can periodically switch sampling positions to achieve multi-angle gas collection.

[0028] like Figure 3 As shown, in this embodiment, multiple first connecting pipes 5 are evenly distributed around the sleeve 4. The first connecting pipes 5 are L-shaped, so that the filter screen on the front side of the air intake plate 6 is on the same vertical plane.

[0029] like Figure 3 As shown, the connecting shell 3 is a hollow shell structure. A fixed brush 8 is mounted on a rod 9. The rod has a rectangular frame structure with a notch on one side for fixing to the connecting shell 3. The fixed brush 8 is vertically fixed to the rod. Figure 1 and Figure 3 As shown, the rod 9 is arranged in a cross shape with one side of the fixed brush 8. The bristles of the fixed brush 8 face the filter screen 7 and are on the same vertical plane as the filter screen.

[0030] During the rotation of the sleeve 4, the fixed brush 8 remains stationary via the rod 9, with its bristles always in close contact with the rotating filter screen 7, continuously scraping away dust and foreign matter adhering to the filter screen 7 to prevent pore blockage. The cleaned filter screen 7 maintains stable air permeability, ensuring continuous airflow.

[0031] The filtered clean gas flows sequentially through the air inlet plate 6, the first connecting pipe 5, the internal cavity of the sleeve 4, and the connecting housing 3, finally converging into the main channel of the gas transmission pipe 1. The pump body 10 continuously pumps the gas in the gas transmission pipe 1 to the carbon emission detector 2, where the carbon dioxide concentration and greenhouse gas components in the gas are detected in real time by sensors.

[0032] Throughout the process, the rotational motion of the sleeve 4 and the static cleaning of the fixed brush 8 work together, while the pump body 10 provides constant suction force to achieve uninterrupted gas sampling, filtration, and detection cycles, ensuring accurate acquisition of carbon emission data inside and outside the building.

[0033] In one embodiment, for the first connecting pipe 5, there are four of each of the first connecting pipe 5, the air intake plate 6, and the filter screen 7, which are evenly distributed on the sleeve 4.

[0034] In one embodiment, the output end of the drive mechanism is provided with a first gear 31, and the circumference of the sleeve is provided with a second gear 30. The first gear 31 and the second gear 30 mesh to realize the rotation of the sleeve 4. The drive mechanism is a waterproof motor 11, and the second gear 30 is fixedly installed at the output end of the waterproof motor 11. The waterproof motor 11 is fixedly installed on the connecting housing 3.

[0035] The working principle of the energy-saving and carbon-reduction effect testing device for buildings proposed in this invention is as follows: After the waterproof motor 11 is started, the first gear 31 at its output end drives the meshing second gear 30 to rotate, causing the sleeve 4 to rotate at a constant speed around the connecting housing 3 as the central axis. The four first connecting pipes 5 and the corresponding air inlet discs 6 evenly distributed on the outer wall of the sleeve 4 rotate synchronously with the sleeve 4, realizing that the four air inlet discs 6 alternately switch the sampling position in the circumferential direction.

[0036] External air is simultaneously drawn in through the surfaces of the filter screens 7 on the four intake discs 6. During rotation, the filter screens 7 move relative to the fixed brushes 8. The fixed brushes 8 are fixed to the connecting housing 3 by rods 9 and remain stationary, continuously scraping the outer surface of the filter screens 7 to remove adhering impurities. The filtered air enters the internal cavity of the sleeve 4 through the four first connecting pipes 5, and during the rotation of the sleeve 4, it flows into the air supply pipe 1 through the connecting port of the connecting housing 3.

[0037] Pump 10 continuously draws the airflow collected in gas delivery pipe 1, pressurizes it, and delivers it to carbon emission detector 2. The rotating sampling mode of the four air intake discs 6 covers a 360° spatial range. Combined with the constant speed controlled by the waterproof motor 11, it realizes continuous and balanced collection of gas samples from multiple directions, ensuring that the detection data comprehensively reflects the carbon emission distribution around the building.

[0038] In one embodiment, the pump body 10 is fixed on the carbon emission detector 2. The carbon emission detector 2 has a display screen 12 on its surface, and guide rods and rotatable first threaded rods are respectively provided on the upper and lower sides of the display screen. The guide rods and the first threaded rods are connected by a cleaning brush. One end of the first threaded rod is connected to a driving component, and the driving component drives the first threaded rod to rotate so that the cleaning brush can clean the display screen.

[0039] Specifically, the carbon emission detector 2 has four connecting blocks 4 at the four corners of the display screen 12. Two connecting blocks 13 at the same height form a group. A guide rod 15 is fixedly installed between the top group of connecting blocks, and a first threaded rod 14 is rotatably installed between the bottom group of connecting blocks. The first threaded rod 14 is threadedly connected to one end of the cleaning brush 16, and the other end of the cleaning brush 16 is slidably connected to the guide rod 15. One end of the first threaded rod 14 is connected to the output end of the micro motor 17, and the micro motor 17 is fixedly installed on one of the connecting blocks 13.

[0040] The working principle of the building energy-saving and carbon reduction effect testing device proposed in this invention is as follows: After the micro motor 17 is started, it drives the first threaded rod 14 to rotate between the two sets of connecting blocks 13. Since one end of the cleaning brush 16 is engaged with the first threaded rod 14 through a threaded hole, and the other end is slidably connected to the guide rod 15 through a sliding sleeve, the rotating first threaded rod 14 forces the cleaning brush 16 to make a linear reciprocating motion along the axial direction of the guide rod 15. During the reciprocating movement, the bristles of the cleaning brush 16 continuously scrape the display screen 12 on the surface of the carbon emission detector 2, removing dust, water stains or dirt adhering to the display screen 12.

[0041] Meanwhile, the pump 10, fixed to the carbon emission detector 2, continues to operate, drawing filtered gas from the gas delivery pipe 1 into the detector for component analysis. Real-time carbon emission data is clearly displayed on the cleaned display screen 12. When the micro motor 17 periodically reverses direction, the cleaning brush 16 repeatedly moves back and forth under the limit of the guide rod 15, forming a full-coverage cleaning path for the display screen 12. The two sets of connecting blocks 13 provide rotational support and sliding guidance functions, respectively, to ensure the stability of the movement trajectory of the cleaning brush 16.

[0042] In one embodiment, for the carbon emission detector 2 described above, the bottom of the carbon emission detector 2 is fixedly connected to the top end of the exhaust pipe 18, and the bottom end of the exhaust pipe 18 is fixedly connected to the filter box 19; an exhaust pipe 20 is fixedly connected to one side of the bottom of the filter box 19.

[0043] After the carbon emission detector 2 completes the gas composition analysis, the detected gas is discharged from the outlet pipe 18 connected to its bottom and enters the filter box 19. The gas is treated by multiple layers of purification media in the filter box 19 to adsorb residual pollutants or harmful substances, and then discharged to the external environment through the exhaust pipe 20 on the side of the filter box 19.

[0044] During this process, the exhaust pipe 18 directs the gas from the bottom of the carbon emission detector 2 to ensure stable internal gas pressure. The filter box 19 performs secondary purification of the gas through physical filtration or chemical adsorption, reducing the environmental impact of the emitted gas. The exhaust pipe 20 can adopt a fixed orientation or diffusion structure design to disperse the purified gas and avoid excessively high local concentrations. The entire gas emission path forms a closed loop, achieving harmless treatment of the detected waste gas.

[0045] In one embodiment, the filter box 19 is supported by a telescopic rod. The bottom end of the telescopic rod is fixed to the fixed plate 23. The telescopic rod includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 is slidably connected inside the second connecting rod 22. The bottom end of the second connecting rod 22 is connected to the fixed plate 23, and the top end is sleeved on the first connecting rod 21. The top end of the first connecting rod 21 is fixed to the filter box 19. The height of the filter box is adjusted by telescopically extending the first connecting rod 21 relative to the second connecting rod 22.

[0046] The second connecting rod 22 is equipped with a worm gear mechanism. A worm 26 is rotatably mounted on the second connecting rod 22, with its main body located inside the second connecting rod 22 and one end extending outside to form a handle. A worm gear 25 is located inside the second connecting rod 22 and fixed to the periphery of the second threaded rod 24. Rotating the worm 26 causes the worm gear to drive the second threaded rod 24 to rotate. The second threaded rod 24 extends inside the first connecting rod 21 and engages with a slider. The slider is fixed inside the first connecting rod 21. Rotation of the first threaded rod 4 causes the slider to drive the first connecting rod 22 to rise and fall. The bottom end of the first threaded rod 4 is rotatably connected to the fixed plate 23 via a bearing.

[0047] In one embodiment, for the carbon emission detector 2, connecting plates 27 are fixedly installed on both sides of the carbon emission detector 2, one connecting plate 27 is fixedly installed with a wind speed detection component 28, and the other connecting plate 27 is fixedly installed with a wind direction detection component 29.

[0048] In one embodiment, for the fixed brush 8, the contact surface between the fixed brush 8 and the filter screen 7 is an arc-shaped structure, as long as the fixed brush 8 can brush the surface of the filter screen 7.

[0049] In one embodiment, the rod 9 is an adjustable telescopic rod, which can adjust the position of the fixed brush 8. When a different size air intake disc is replaced, the position of the fixed brush 8 can be adjusted accordingly.

[0050] The height of the filter box 19 is adjusted by the worm gear 26: manually rotating the worm gear 26 drives the worm wheel 25 and the second threaded rod 24 to rotate, forcing the first connecting rod 21 to slide up and down in the second connecting rod 22, thereby adjusting the vertical distance between the filter box 19 and the fixed plate 23 to adapt to different installation environments.

[0051] Meanwhile, the wind speed detection component 28 on the connecting plates 27 on both sides of the carbon emission detector 2 monitors the airflow speed in real time, and the wind direction detection component 29 collects wind direction data. Both are fed back to the detector via electrical signals to dynamically correct the gas sampling efficiency. The micro motor 17 drives the first threaded rod 14 to rotate, causing the cleaning brush 16 to reciprocate along the guide rod 15, continuously cleaning the surface of the display screen 12 to ensure data visibility. Both the wind direction detection component 29 and the wind speed detection component 28 are existing technologies.

[0052] Example 2 like Figures 1-6 As shown, a method for operating a building energy conservation and carbon reduction effect testing device, which uses the building energy conservation and carbon reduction effect testing device of Embodiment 1, includes the following steps: Under the action of the pump body 10, the gas enters the carbon emission detector 2 through the air inlet plate 6, the first connecting pipe 5, the sleeve 4, the connecting housing 3, and the gas delivery pipe 1. The carbon emission detector 2 detects the carbon dioxide concentration and greenhouse gas components in the gas in real time. The gas passes through the filter screen 7 of the air inlet plate 6, and the filter screen 7 intercepts particulate matter and impurities in the air.

[0053] The waterproof motor 11 drives the sleeve 4 to rotate around the connecting housing 3 via the first gear 31 and the second gear 30, which in turn drives the first connecting pipe 5 and the air intake plate 6 fixed thereon to rotate synchronously, so that multiple air intake plates can periodically switch sampling positions to achieve multi-angle gas collection. At the same time, the fixed brush 8 is in close contact with the rotating filter screen 7 surface to continuously scrape off the dust and foreign objects attached to the filter screen.

[0054] The exhaust pipe 18 directs gas from the bottom of the carbon emission detector 2 into the filter box 19, ensuring stable internal gas pressure. The filter box 19 performs secondary purification of the gas through physical filtration or chemical adsorption, reducing the environmental impact of the exhaust gas. The purified gas is discharged from the exhaust pipe 20. The wind speed detection components 28 on the connecting plates 27 on both sides of the carbon emission detector 2 monitor the airflow speed in real time, and the wind direction detection components 29 collect wind direction data. Both are fed back to the detector via electrical signals to dynamically correct the gas sampling efficiency.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
