DETAILED DESCRIPTION

[0021] like Figures 1 to 3As shown, the present invention provides a carbon emission monitoring device for construction engineering, comprising: a cylinder 1, a first end of the cylinder 1 is provided with an air inlet 101, a second end of the cylinder 1 is provided with an air outlet 102, an air suction fan 2 is rotatably installed in the cylinder 1 on the side away from the air inlet 101, the air suction fan 2 is driven by a first motor 201 fixedly installed in the cylinder 1, an output end of the first motor 201 is fixedly connected to the air suction fan 2, a carbon emission monitor 3 is fixedly installed in the cylinder 1, the carbon emission monitor 3 is arranged on the side of the air suction fan 2 away from the air inlet 101, a protective net 4 and a dustproof cloth 5 are sequentially arranged in the cylinder 1 near the air inlet 101 along the air inlet direction, the protective net 4 is fixedly installed in the air inlet 101, an annular space 103 connected to the inside of the cylinder 1 is provided in the cylinder 1, the dustproof cloth 5 is movably installed in the annular space 103 through a bracket 7, the A gap is provided between the outer wall of the bracket 7 and the inner wall of the annular space 103, and a groove 705 cooperating with the dustproof cloth 5 is provided on the bracket 7, and the dustproof cloth 5 is fixedly installed in the groove 705. A fixing frame 6 is fixedly installed in the cylinder 1 on the side of the dustproof cloth 5 away from the protective net 4, and a slide groove 601 is provided in the middle of the fixing frame 6. A slider 602 is installed in the slide groove 601 for limited sliding. The first spring 603 is fixedly connected between the two side walls opposite to the slider 602 and the two side walls opposite to the slide groove 601 respectively, and a second motor 604 is fixedly installed on the side of the slider 602 away from the dustproof cloth 5, and the output shaft 605 of the second motor 604 is rotatably connected to the slider 602, and the output shaft 605 extends out of the slider 602 end and is fixedly connected to the bracket 7, and a fan-shaped counterweight block 704 is eccentrically provided on the bracket 7 to make the center of gravity of the output shaft 605 deviate from the center of the output shaft 605 along the radial direction of the output shaft 605.

[0022] In this solution, the suction fan 2 is started to allow the air outside the cylinder 1 to enter the cylinder 1 through the protective net 4 and the dustproof cloth 5 in sequence from the air inlet 101, and the carbon emission monitor 3 monitors the carbon dioxide content of the air entering the cylinder 1 in real time; wherein, when the dustproof cloth 5 needs to be cleaned, the second motor 604 is started to drive the output shaft 605 to rotate, thereby driving the bracket 7 to rotate, thereby driving the dustproof cloth 5 to rotate, so that the dustproof cloth 5 is scattered and separated from the dustproof cloth 5 under the action of the rotating centrifugal force, and because the second motor 604 is fixed to the slider 60 2, the slider 602 is slidably installed in the slide groove 601. Due to the setting of the fan-shaped counterweight block 704, the center of gravity of the output shaft 605 deviates from the center of the output shaft 605 along the radial direction of the output shaft 605. When the output shaft 605 rotates, it will drive the slider 602 to slide back and forth in the slide groove 601 under the action of the first spring 603, so that the dustproof cloth 5 shakes back and forth along the axial direction of the first spring 603 during the rotation, thereby further shaking off the dust on the dustproof cloth 5; wherein, the annular space 103 is used to provide a moving space for the dustproof cloth 5.

[0023] This solution can monitor the carbon dioxide content in the air in real time by setting up a carbon emission monitor 3, and can prevent external debris from entering the cylinder 1 by setting up a protective net 4, and prevent external dust from entering the cylinder 1 by setting up a dustproof cloth 5. The output shaft 605 cooperates with the fan-shaped counterweight block 704 to make the dustproof cloth 5 vibrate back and forth along the axial direction of the first spring 603 during rotation, so that the dust on the dustproof cloth 5 is separated from the dustproof cloth 5 under the action of centrifugal force and reciprocating vibration, thereby ensuring the dust removal effect and avoiding friction damage to the dustproof cloth 5 caused by cleaning the dustproof cloth 5 with a brush.

[0024] In one embodiment of the present invention, the inner wall of the annular space 103 is circumferentially provided with a plurality of mounting grooves 104 with the axis of the annular space 103 as the center, a knocking rod 105 is slidably installed in the mounting groove 104, a second spring 106 is fixedly connected between the knocking rod 105 and the inner wall of the mounting groove 104, a plurality of fixed blocks 701 are circumferentially fixedly provided on the outer wall of the bracket 7 with the axis of the annular space 103 as the center, the fixed block 701 is provided with an inclined edge 702 on the side close to the knocking rod 105 along the rotation direction of the bracket 7, the inclined edge 702 is inclinedly provided along the side away from the knocking rod 105, and the fixed block 701 is provided with a vertical edge 703 arranged along the radial direction of the bracket 7 on the side away from the knocking rod 105 along the rotation direction of the bracket 7.

[0025] In the present solution, when the bracket 7 drives the dustproof cloth 5 to rotate, the fixed block 701 is driven to rotate along with the bracket 7. When the fixed block 701 is close to the knocking rod 105, the knocking rod 105 is squeezed by the inclined edge 702, so that the knocking rod 105 moves toward the inside of the installation groove 104. After the fixed block 701 passes the knocking rod 105, due to the setting of the vertical edge 703, the knocking rod 105 moves to the outside of the installation groove 104 under the action of the second spring 106 and falls on the outer wall of the bracket 7, thereby realizing the knocking function of the knocking rod 105 on the bracket 7, so as to further shake off the dust on the dustproof cloth 5 and improve the cleaning effect of the dustproof cloth 5.

[0026] In one embodiment of the present invention, the cylinder body 1 includes a main cylinder 107 and a branch cylinder 108 vertically arranged on the main cylinder 107, the air inlet 101 is arranged at one end of the main cylinder 107, the air outlet 102 is arranged at the end of the branch cylinder 108 away from the main cylinder 107, the first motor 201, the air suction fan 2 and the carbon emission monitor 3 are all arranged in the branch cylinder 108, the main cylinder 107 is closed at the end away from the air inlet 101, a blowing fan 109 is rotatably installed in the main cylinder 107, the branch cylinder 108 is arranged between the blowing fan 109 and the fixed frame 6, and the blowing fan 109 is driven by a third motor 110 fixedly installed outside the main cylinder 107.

[0027] In the present solution, when the second motor 604 is started to drive the dustproof cloth 5 to move for dust removal, the third motor 110 is simultaneously started to drive the blowing fan 109 to rotate, thereby blowing the dust adhering to the dustproof cloth 5 to the outside of the cylinder 1, further improving the dust removal effect on the dustproof cloth 5, and blowing the dust to the outside of the cylinder 1; and when the blowing fan 109 rotates, it can have a heat dissipation effect on the second motor 604, and the third motor 110 is fixedly installed outside the main cylinder 107, avoiding the problem of excessively high internal temperature of the main cylinder 107 and difficulty in installation and maintenance caused by setting the third motor 110 in the main cylinder 107.

[0028] In one embodiment of the present invention, a protective cover 8 is installed at the end of the branch tube 108 away from the main tube 107, and an annular gap is provided between the inner wall of the protective cover 8 and the outer wall of the branch tube 108. An annular dustproof cloth 801 is installed in the annular gap. The outer wall of the branch tube 108 is circumferentially provided with multiple air outlets 102 centered on the axis of the branch tube 108, and the interior of the branch tube 108 is connected to the annular gap through the air outlet 102.

[0029] In this solution, the annular gap is set to make the air outlet direction vertically downward, and the annular dustproof cloth 801 is set to prevent external dust from entering the cylinder 1 from the air outlet 102, and during the air outlet process, the dust adhering to the annular dustproof cloth 801 can be blown off.
