Description

Technical Field

[0001] This utility model relates to the field of dust monitoring technology, specifically a dust monitoring device for construction sites. Background Technology

[0002] Dust monitoring refers to the process of detecting and monitoring dust and particulate matter suspended in the air. Dust monitoring is often used in construction sites. Dust contains a large number of fine particulate matter, and long-term inhalation is harmful to human health, especially the respiratory system. Dust monitoring can monitor values ​​and issue early warnings in a timely manner, and also facilitate timely dust control measures to reduce the threat to public health.

[0003] Existing dust monitoring devices use sampling heads that are fixed and open to the top. In calm weather, the air is relatively static, and the samples entering the sampling head are close to the surrounding environment. However, in windy weather, the amount of sample entering the sampling head is reduced due to the wind direction and the sampling head itself blocking the airflow. This results in a larger discrepancy between the sample inside the sampling head and the surrounding environment, thus affecting the accuracy of the monitoring data. Utility Model Content

[0004] The purpose of this invention is to provide a construction site dust monitoring device to solve the problem mentioned in the background art of existing dust monitoring devices. Because the sampling head for collecting air is fixed with its opening facing upwards, the air is relatively static in calm weather, and the sample entering the sampling head is relatively close to the surrounding environment. However, in windy weather, due to the different wind direction and the obstruction of the sampling head itself, the amount of sample entering the sampling head will decrease, resulting in a large error between the sample inside the sampling head and the surrounding environment, thus affecting the accuracy of the monitoring data.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction site dust monitoring device, comprising a support frame and dust monitors, and further comprising a direction adjustment component, wherein the direction adjustment component is mounted on the support frame, the direction adjustment component comprises a housing and a rotation drive component, wherein multiple dust monitors are arranged on the direction adjustment component, and the rotation drive component drives each dust monitor to rotate synchronously around its own axis.

[0006] Preferably, the rotating drive component includes a motor, a large gear, and a small gear. The motor body is fixed to the bottom plate inside the housing. The output end of the motor is connected to the large gear. Multiple small gears are meshed around the large gear. The number of small gears is the same as that of the dust monitors. The bottom end of the small gear is rotatably connected to the bottom surface inside the housing. The top end of the small gear passes through a slot in the top plate of the housing and is fixedly connected to the dust monitor.

[0007] Preferably, the dust monitor includes a housing and a dust sensor, with one side of the housing being open and the dust sensor installed inside the housing.

[0008] Preferably, an observation component is installed on the upper surface of the housing. The observation component includes a frame and a camera. The frame is fixed to the housing, the camera is installed below the frame, and a wind direction sensor is installed on the housing directly below the camera.

[0009] Preferably, the observation component further includes a display screen, which is mounted above the frame, and two sets of the display screens are arranged facing each other.

[0010] Preferably, the support frame includes a base, a fixing member, a movable member, a limiting member, and a connecting plate. One end of the fixing member is fixed to the base, and the other end is connected to the movable member. The movable member passes through the interior of the fixing member. The other end of the movable member is fixedly connected to the connecting plate. The bottom of the housing of the direction adjustment assembly is fixedly connected to the connecting plate. The limiting member is threaded and passes through the side wall of the fixing member. When the limiting member is tightened, one end of the limiting member inside the fixing member abuts against the movable member.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a direction adjustment component and a dust monitor, allows the pointer of the wind direction sensor to rotate with the wind direction in windy weather. When the wind direction sensor changes, the direction adjustment component can drive the dust monitor to rotate, so that the cover is aligned with the direction of the wind. When the dust monitor is aligned with the wind direction, the monitoring sample that can enter the cover is more similar to the sample in the environment than the sample collected by traditional methods. This can reduce the error in monitoring data caused by the inconsistent angle between the wind direction and the cover and the missing sampling, and improve the accuracy of dust monitoring results at construction sites in windy weather. 2. This utility model, by setting up multiple dust monitors, can simultaneously monitor dust in the environment and collect multiple data points. Using multiple data points to judge the results reduces possible errors during monitoring and improves the accuracy of the monitoring results. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] One embodiment provided by this utility model: as follows Figure 1 As shown, a construction site dust monitoring device includes a support frame 1, a direction adjustment component 2, a dust monitor 3, an observation component 4, and a wind direction sensor 5.

[0021] like Figure 2 As shown, the support frame 1 includes a base 11, a fixing member 12, a movable member 13, a limiting member 14, and a connecting plate 15. One end of the fixing member 12 is fixed to the base 11, and the other end is connected to the movable member 13. The movable member 13 passes through the interior of the fixing member 12, and the other end of the movable member 13 is fixedly connected to the connecting plate 15. The limiting member 14 is threaded and passes through the side wall of the fixing member 12. When the limiting member 14 is tightened, one end of the limiting member 14 inside the fixing member 12 abuts against the movable member 13. The dust monitoring device can be placed in a suitable location according to the needs of the construction site. The base 11 is fixed to the ground to increase the stability of the monitoring device, ensuring normal monitoring even in windy weather with heavy dust. After the device is installed, the support frame 1 is adjusted according to the height of dust to be monitored. The movable part 13 has a handle that extends out of the through groove of the fixed part 12. Moving the handle up and down can move the movable part 13 up and down as a whole. When it is moved to a suitable height, the limiting part 14 is tightened so that the movable part 13 and the fixed part 12 are relatively fixed.

[0022] like Figure 2 and Figure 3 As shown, the direction adjustment assembly 2 includes a housing 21 and a rotation drive component. A connecting plate 15 is fixedly connected to the bottom of the housing 21 of the direction adjustment assembly 2. Multiple dust monitors 3 are installed on the direction adjustment assembly 2. During installation, the entire direction adjustment assembly 2 is then mounted on the height-adjusted support frame 1, and the dust monitors 3 are installed on the direction adjustment assembly 2. By setting multiple dust monitors 3, the dust in the environment can be monitored simultaneously and multiple data points can be collected. Using multiple data points to determine the results reduces potential errors during monitoring and improves the accuracy of the monitoring data.

[0023] like Figure 4 As shown, the dust monitor 3 includes a housing 31 and a dust sensor 32. One side of the housing 31 is open, and the dust sensor 32 is installed inside the housing 31. The housing 31 is horizontally positioned, changing its angle with the wind direction, allowing air samples to directly enter and be sampled during windy weather without obstruction. Compared to traditional sampling heads, the data obtained from the sampled samples is more accurate. The dust sensor 32 calculates the concentration of particulate matter entering the housing 31.

[0024] like Figure 2 and Figure 5 As shown, the rotation drive includes a motor 22, a large gear 23, and small gears 24. The motor 22 is fixed to the bottom plate inside the housing 21. The output end of the motor 22 is connected to the large gear 23. Multiple small gears 24 are meshed around the large gear 23. The number of small gears 24 is the same as the number of dust monitors 3. The bottom end of the small gear 24 is rotatably connected to the bottom surface inside the housing 21, and the top end of the small gear 24 passes through a slot in the top plate of the housing 21 and is fixedly connected to the dust monitor 3. All dust monitors 3 are oriented in the same direction. When the motor 22 drives the large gear 23 to rotate, all the small gears 24 on the periphery rotate accordingly, thereby achieving synchronous rotation of each dust monitor 3 around its own axis.

[0025] like Figure 6 As shown, an observation assembly 4 is mounted on the upper surface of the housing 21. The observation assembly 4 includes a frame 41 and a camera 42. The frame 41 is fixed to the housing 21, and the camera 42 is mounted below the frame 41. A wind direction sensor 5 is mounted on the housing 21 directly below the camera 42. The axes of the camera 42, the wind direction sensor 5, and the motor 22 are all on the same line. The angle between the wind direction sensor 5 and the dust monitor 3 can be remotely monitored through the camera 42, and any malfunctions can be repaired promptly.

[0026] The observation component 4 also includes a display screen 43, which is mounted above the frame 41. Two sets of display screens 43 are arranged facing each other. The two sets of display screens 43 facing each other allow for observation of dust data in the environment from multiple angles.

[0027] In windy weather, the pointer of the wind direction sensor 5 rotates with the wind direction. When monitoring dust at the construction site, the logic judgment module connected to the wind direction sensor 5 transmits a signal to the execution module. The execution module controls the motor 22 to drive the motor, and the large gear 23 rotates, driving the small gear 24 to rotate, thus rotating all the dust monitors 3 so that the housing 31 is aligned with the direction of the wind. Air enters from the opening of the housing 31 and flows out from the opposite hole. At this time, because the dust monitors 3 are aligned with the wind direction, the monitoring samples that can enter the housing 31 are more similar to the samples in the environment than those collected by traditional methods. This reduces the error in monitoring data caused by inconsistent wind direction and housing 31 angles or missing samples, and improves the accuracy of dust monitoring results at construction sites in windy weather. After the samples enter the housing 31 of each dust monitor 3, the dust sensor 32 transmits the measurement data to the background management system and the display screen 43 for easy statistical analysis and observation of the data results.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
