Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and more specifically, to a carbon emission monitoring device for asphalt roads. Background Art

[0002] In the process of producing asphalt mixtures, a large amount of greenhouse gases such as carbon dioxide are generated due to the need to heat asphalt and other raw materials at high temperatures. Similarly, during the paving process of asphalt roads, carbon emissions are also released in links such as the operation of construction machinery, the laying and compaction of asphalt. These emissions not only pollute the environment but also run counter to the low-carbon concept advocated by modern life.

[0003] In order to monitor and control these carbon emissions, some gas detection sensors have emerged. These sensors can monitor the carbon emission situation at the construction site in real time and provide data support for environmental protection departments. However, in actual applications, since the construction site is often dusty, a large amount of dust will affect the measurement accuracy of the monitoring device. Although some monitoring equipment has been equipped with filter cloths to filter dust, the use effect of the filter cloths is difficult to last. As time goes by, the filter cloths will gradually accumulate dust and impurities, and their filtering ability will gradually decline. Therefore, inaccurate measurements will also occur due to the failure of the filter cloths during monitoring. Summary of the Invention

The frame is fixed inside the housing. The control unit is connected with a wireless communication unit.

[0041] The carbon emission monitoring device further includes a material storage unit, a material receiving box 8, an image acquisition unit 9, and two limiting units; the installation position is in the shape of a U-shaped notch and has a U-shaped slot 5.2, and the filtering unit 6 includes a plug board 6.2 having an installation through hole and capable of being inserted into the U-shaped slot 5.2, a first end block 6.3 connected to the plug board 6.2, and a second end block 6.4 connected to the plug board 6.2.

The arc-shaped rod 10.1 has an arc-shaped guide groove 10.1.1 matched with the arc-shaped guide rail 10.3. The arc-shaped limiting plates 10.2 of the two limiting units can make the bottom end of the blanking position open, so that the filtering unit 6 at the blanking position falls into the material receiving box 8, and the arc-shaped limiting plates 10.2 of the two limiting units can also make the bottom end of the blanking position closed, so that the filtering unit 6 at the blanking position does not discharge materials.

[0042] The arc-shaped rod 10.1 is fixedly connected to the frame through a connecting rod 10.7; one end of the electric telescopic rod 10.6 is hinged to the first hinge seat 10.4, and the other end is hinged to the second hinge seat 10.5. The second push plate 7.3 abuts against the filter unit 6 closest to the second push plate 7.3. The gas detection unit 4 is a non-dispersive infrared (NDIR) sensor or a tunable diode laser absorption spectroscopy (TDLAS) sensor. The gas detection unit 4 includes a measurement chamber, and both the first air outlet pipe 2 and the second air outlet pipe 3 are connected to the measurement chamber. There are 8 installation positions of the turntable 5 and they are evenly distributed in a ring. The radius corresponding to the inner arc surface of the arc-shaped limiting plate 10.2 is greater than or equal to the radius of the turntable 5 and the difference from the radius of the turntable 5 is less than 1 mm. The image acquisition unit 9 includes a mounting plate 9.1, an image acquisition device 9.2 mounted on the mounting plate 9.1, and a light source unit 9.3 mounted on the mounting plate 9.1.

[0043] The storage rack and the electric lifting rod 7.7 are both installed at the frame. The first push plate 7.1 is provided with a guide hole, and the second push plate 7.3 is connected with a guide rod 7.10 that cooperates with the guide hole. There are two of the second motor 7.5.1, bearings and the lead screw 7.9. The first push plate 7.1 is provided with two third guide grooves. The first push plate 7.1 is provided with two guide holes, and the second push plate 7.3 is provided with two guide rods 7.10. The plug plate 6.2, the first end block 6.3 and the second end block 6.4 have flush arc surfaces, and the radius corresponding to the arc surface is equal to the radius of the turntable 5. A filter screen unit 1.1 is installed at the end of the air inlet pipe 1.

[0044] Working principle: As shown in the figure, there are multiple mounting positions at the turntable of this application. Filter units are installed at the mounting positions, and there are multiple filter units at the storage rack. The second push plate abuts against the filter unit, and the multiple filter units abut against each other. Although the filter unit abutting against the first end plate is located at the blanking gap, it will not move downwards because it is tightly abutted by the adjacent filter unit. However, under the downward driving of the pressing block, the filter unit can move down along the vertical guide rail to the loading position. And due to the self-weight of the filter unit, the filter unit stably cooperates with the U-shaped slot. And due to the limitation of the two arc-shaped limiting plates, during the rotation of the turntable, the filter unit will not fall off from the U-shaped slot. As the turntable rotates, the filter unit can rotate to the filtering and dust-removing position for filtering and dust-removing. Due to the suction of the fan, the sample gas coming in from the air inlet pipe is dust-removed after passing through the filter cloth and then enters the gas detection unit for the determination of carbon emissions, so that the determination of carbon emissions is more accurate. After using for a set time, the dust on the surface of the filter cloth will increase and the required dust-removing effect cannot be achieved. Thus, the turntable continues to rotate, and the filter unit is rotated to the blanking position, and then falls into the receiving box under the action of gravity. Thus, multiple filter units can be used one by one for filtering and dust-removing. But after a period of time, the bottom end of the blanking position can be closed by the two arc-shaped limiting plates, so that the used filter unit will not fall from the blanking position and will be rotated to the image acquisition position. Thus, the image acquisition unit at the image acquisition position can perform image acquisition, and then judge the dust contamination situation of the filter cloth according to the acquired image. According to the dust contamination situation of the filter cloth, if the dust is too much (indicating that the time of the filter unit is too long and actually cannot achieve the required dust-removing effect in the later stage), the replacement frequency of the filter unit can be increased. If the dust is less (indicating that the time of the filter unit is too short and actually can still be used for a period of time), the replacement frequency of the filter unit can be reduced. And according to the need, two consecutive filter units can also pass through the image acquisition unit, so as to increase the accuracy of the evaluation of the usage situation of the filter unit. And after the image acquisition of the filter unit is completed, the two arc-shaped limiting plates can be made to open the bottom end opening of the blanking position, and the turntable can be rotated in the reverse direction to discharge the filter unit at the image acquisition position from the blanking position into the receiving box again.

[0045] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
