Description

Technical Field

[0001] The embodiments of this specification relate to the technical field of construction monitoring, and particularly to a dust monitoring device. Background Art

[0002] During the construction process, a large amount of dust may be generated in links such as earthwork excavation, slope construction, on-site milling, demolition of existing roads, loading, unloading and stacking of building materials and construction waste, and muck removal. Dust not only affects air quality and reduces visibility, but may also damage environmental elements such as vegetation, water bodies and soil. By installing a dust monitoring device at the construction site to monitor the dust concentration in real time and taking timely measures to control dust pollution, the health of surrounding residents and environmental quality can be guaranteed.

[0003] As an important part of green construction at the construction site, most of the currently used equipment for dust monitoring is an online dust monitoring system. This online dust monitoring system has high accuracy and can accurately reflect the content of PM2.5 in the on-site air. However, the online dust monitoring system needs to be fixed at a specified height and cannot move, so it cannot monitor the dust situation outside the monitoring range in real time. Moreover, the entire set of the online dust monitoring system is relatively expensive, which is a large expenditure for construction projects. In addition, the online dust monitoring system uses sophisticated electronic equipment and requires special personnel to maintain and repair it during normal use, increasing the expenditure of human and material resources.

[0024] The following will describe in detail a dust monitoring device according to an embodiment of the present specification with reference to the accompanying drawings. Figure 1 The structural schematic diagram of a dust monitoring device according to an embodiment of the present specification is shown. The present specification provides a dust monitoring device, including: a vertical rod 1, a bracket 2, and a support 3; the bottom of the vertical rod 1 is connected to the support 3; the bracket 2 includes a wooden formwork 21 and a tray 22, and the tray 22 is used to support the wooden formwork 21; the tray 22 is sleeved outside the vertical rod 1, and the tray 22 moves relative to the vertical rod 1 in its height direction, and the tray 22 is fixed at any position of the vertical rod 1 through a fixing piece 23, so that the wooden formwork 21 accumulates dust and ash at different heights. The staff calculates the actual on-site dust situation by regularly counting the dust and ash accumulated on the wooden formwork 21.

[0025] A circular tube 24 is provided at the bottom of the tray 22. For example, the circular tube 24 can be welded to the bottom of the tray 22. The bottom of the tray 22 has a through hole communicating with the circular tube 24, and the tray 22 is sleeved outside the vertical rod 1 through the circular tube 24. In addition, the circular tube 24 can also be integrally formed with the tray 22. The circular tube 24 moves relative to the vertical rod 1 in its height direction, and the circular tube 24 is fixed at any position on the vertical rod 1 through the fixing member 23.

[0026] A number of fixing holes are respectively provided on the circular tube 24 and the vertical rod 1 in the length direction, and the fixing member 23 passes through the fixing holes of the circular tube 24 and the vertical rod 1 to fix the height of the tray 22.

[0027] The fixing member 23 includes a screw and a nut. The nut is screwed tightly at both ends of the screw to realize the fastening of the bracket 2. In addition, the fixing member 23 can also be a bolt.

[0028] To ensure that the monitoring height of the dust monitoring device meets the requirements of each construction stage, after the bracket 2 is installed, the height from the upper surface of the bracket 2 to the ground should meet 0.5 m or 1.5 m (the height can also be determined according to the actual site requirements), and the opening position of the fixing hole also needs to be determined according to the actual situation to meet the above requirements.

[0029] First, determine the fixed height. Select the required ones from the several fixing holes on the vertical rod 1 according to the fixed height, and use the screw and nut or bolt to pass through the fixing holes on the circular tube 24 and the vertical rod 1 to realize height fixation. If positioning is carried out through the screw, two nuts are arranged at both ends of the screw to prevent the screw from slipping out of the fixing hole.

[0030] Figure 2 Shows Figure 1 The upward view of the bracket in, and the tray 22 is an I-shaped structure composed of cross beams.

[0031] The cross beams on both sides of the tray 22 are provided with edges for limiting the wooden formwork 21 within the tray 22, and the edges are arranged to be of the same length as the cross beams on both sides. The wooden formwork 21 is a black square wooden board, and the black wooden formwork 21 can more intuitively reflect the situation of the accumulated dust and ash, which is convenient for the staff to monitor. Among them, the shape of the wooden formwork 21 is not limited and can be square, rectangular, circular or polygonal, preferably square.

[0032] A through hole is provided on the cross beam in the middle of the tray 22, and the tray 22 is sleeved outside the vertical rod 1 through the through hole. The position of the through hole provided on the tray 22 is not limited, and the through hole on the tray 22 can be on the side or in the center of the tray 22. When the through hole of the tray 22 is on the side, the formwork 21 can be provided with a through hole on the side. The formwork 21 is sleeved outside the vertical rod 1 and placed on the tray 22, and the formwork 21 moves up and down along the height direction of the vertical rod 1 with the tray 22; alternatively, the formwork 21 is not provided with a through hole and is directly placed on the tray 22, and the formwork 21 moves up and down along the height direction of the vertical rod 1 with the tray 22. When the through hole of the tray 22 is in the center, the formwork 21 can be provided with a through hole in the center. The formwork 21 is sleeved outside the vertical rod 1 and placed on the tray 22, and the formwork 21 moves up and down along the height direction of the vertical rod 1 with the tray 22.

[0033] A through hole is also provided in the center of the formwork 21, and the formwork 21 is sleeved outside the vertical rod 1 through the through hole.

[0034] A reflective sticker is attached to the vertical rod 1 to prevent vehicles and pedestrians from accidentally colliding with the dust monitoring device during night activities. A scale is provided on the vertical rod 1 to determine the fixed height of the tray 22.

[0035] When the dust monitoring device is not in use, to avoid the dust monitoring device occupying too much space, the vertical rod 1 is a telescopic rod.

[0036] The bracket 3 connected to the vertical rod 1 is a hollow tetrahedral structure, which is composed of three equal-length steel bars evenly distributed around the vertical rod 1. The angle between each steel bar of the bracket 3 and the ground should be 45 - 60 degrees to ensure the stability of the overall device placement.
