Description

Technical Field

[0001] The utility model relates to the field of air detection, in particular to an air detection device after blasting construction. Background Technique

[0002] After blasting construction, some harmful gases, particulate matters and odors will be generated in the air, which may affect the surrounding environment and human health. The harmful gases include organic gases, hydrogen sulfide, carbon monoxide, etc. released by the explosion of explosives. Some unpleasant odors, such as sulfides, may be released during the blasting process, causing adverse effects on the surrounding environment.

[0003] After blasting construction, the next step of construction needs to be carried out. Before starting the next step of construction, it is necessary to detect the air quality at the site. However, since the site is still in a dangerous state after blasting, it will threaten the life safety of construction workers to enter the site to detect the air rashly. An air detection device that can move automatically is needed to enter the site after blasting for detection. Since there are many crushed stones at the site after blasting, the crushed stones will fly when the air detection device moves, so it is necessary to reinforce the air detection device. Most of the existing air detection devices are small indoor air detection devices with low shell quality. In addition, there are air detection robots with high costs. Therefore, we propose an air detection device after blasting construction. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the 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 shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , an air detection device after blasting construction, including a housing 1, a brush 2, an air detection structure and a moving structure. The brush 2 is fixedly connected to the outer plane of the housing 1. Three shock-absorbing universal wheels 5 are fixedly connected to the edge position of the outer plane of the housing 1. The three shock-absorbing universal wheels 5 are inside the brush 2 and are evenly distributed in a ring shape. An air intake hole group 3 is opened at the dome position of the housing 1. An air detection structure is provided inside the housing 1, and the position of the housing 1 corresponds to the position of the air intake hole group 3.

[0026] Furthermore, the moving structure includes a shock-absorbing universal wheel 5 and a receiver circuit board 11. The receiver circuit board 11 is fixedly connected to the inner plane of the air intake hole group 3. The position of the receiver circuit board 11 corresponds to the position of one of the shock-absorbing universal wheels 5. The ground at the blasting construction site is rough with gravel, and the structure of the shock-absorbing universal wheel 5 can well adapt to this environment. The receiver circuit board 11 is connected to the shock-absorbing universal wheel 5.

[0027] Further, the air detection structure includes a sampling chamber 8, a detection chamber 10, an air quality sensor 14, and a circuit board 15. The sampling chamber 8 is a hollow frustum-shaped structure. The larger-radius end of the sampling chamber 8 is fixedly connected to the inside of the dome of the housing 1. The position of the sampling chamber 8 corresponds to the position of the air intake hole group 3. The smaller-radius end of the sampling chamber 8 is fixedly connected to a fan 9. The other end of the fan 9 is fixedly connected to the detection chamber 10. A connection port 13 is provided at the other end of the detection chamber 10. An air quality sensor 14 is provided in the connection port 13. One end of the air quality sensor 14 is inside the detection chamber 10, and the other end of the air quality sensor 14 is fixedly connected to the circuit board 15. The circuit board 15 is attached to the outside of the detection chamber 10 and fits with the detection chamber 10. The fan 9 is wired to the outside and can be powered on when needed.

[0028] Further, a display screen 6 is fixedly connected to the outside of the plane of the housing 1. The display screen 6 is data-connected to the circuit board 15 inside the housing 1. The position of the display screen 6 avoids the position of the shock-absorbing universal wheels 5. The data detected by the air quality sensor 14 and the circuit board 15 are displayed on the display screen 6.

[0029] Further, a maintenance port 12 is provided at the center position of the plane of the housing 1. A cover plate 7 is provided outside the plane of the housing 1. The cover plate 7 is connected to the housing 1 by screws. The position of the cover plate 7 corresponds to the position of the maintenance port 12. There are many internal circuit components in the device and the number of maintenance times is relatively large, so the maintenance port 12 and the cover plate 7 are needed.

[0030] Further, a handle 4 is fixedly connected to the outside of the arch of the housing 1. Installing the handle 4 facilitates carrying the device and observing the display screen 6.

[0031] Working principle: After the blasting construction is completed, it is necessary to detect the air quality at the blasting site. Operate the remote control. The remote control is signal-connected to the receiver circuit board 11. The receiver circuit board 11 makes the shock-absorbing universal wheels 5 move according to the instructions of the remote control. During the movement, the gravel and dust on the ground are blocked outside by the brush 2. When reaching the position where the air needs to be detected, the air enters the sampling chamber 8 and the detection chamber 10 from the air intake hole group 3. After the air collection is completed, the remote control can be operated to make the device return. At this time, the data detected by the air quality sensor 14 and the circuit board 15 are updated on the display screen 6. The staff can turn the device through the handle 4 to observe and record the data displayed on the display screen 6. After the detection is completed, start the fan 9 to discharge the dust in the sampling chamber 8 and the detection chamber 10. When it is necessary to repair the internal components of the housing 1, unscrew the screws on the cover plate 7 and remove the cover plate 7 to repair and check the inside.
