[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction in my country, various construction sites and road construction sites are increasing. Chinese utility model patent, authorized announcement number "CN219141897U", discloses a real-time monitoring device for construction site dust and noise. In this utility model, through the linkage between the support rod, mounting rod, and fastening bolts, the device can be quickly adjusted to the corresponding position when monitoring different high-rise locations on the construction site is required. Simultaneously, when frequent movement of the monitoring device is needed, the movable wheels at the bottom of the mounting base allow for rapid movement to the appropriate position. The dust sensor, noise detector, and anemometer installed on the mounting rod can monitor dust, noise, and wind speed and direction at the construction site, displaying the data on the screen. When dust and noise exceed standards, the construction site can be quickly adjusted to avoid work stoppages and rectification.

[0003] The above-mentioned technical solutions are not convenient for monitoring high-altitude locations during use. Since the ground-mounted equipment mainly monitors the dust concentration at lower altitudes, it is insufficient for monitoring the dust diffusion at higher locations. Moreover, the diffusion of construction site dust in the air is three-dimensional, and the dust concentration at different heights may vary. Relying solely on ground-mounted equipment is insufficient to comprehensively and accurately reflect the dust pollution status of the entire construction site. Therefore, we propose a construction site dust monitoring and alarm device. Utility Model Content

Support column 9: The top end is fixedly connected to the bottom of the control box 2, and the bottom end is rotatably connected to the inside of the rotating frame 6. Two through holes 15 are opened on the outer surface. By cooperating with the screw 16, the control box 2 is fixed on the rotating frame 6 and the angle is adjusted to ensure that the control box 2 is kept horizontal or at a suitable monitoring angle.

[0022] Example 1: like Figure 1-4 As shown, at a construction site, there is a relatively thick wall made of a mixture of concrete and bricks. It is necessary to install a dust monitoring and alarm device on this wall for long-term monitoring.

[0023] The two wall mounting plates 7 are made of thickened stainless steel with rust-proof treatment. Due to the hardness of the wall material, the mounting holes on the wall mounting plates 7 are designed with a large diameter. Long and thick expansion bolts are used to pass through the four through holes on the top of the fixing base 1 and the mounting holes on the wall mounting plates 7 to firmly fix the equipment to the wall.

[0024] The rotating frame 6 is welded to the wall mounting plate 7 to ensure the connection strength. The support column 9 is stably connected to the rotating frame 6 through screw 16. The control box 2 and the mounting frame 5 above it, the noise detector 11, the wind speed and direction meter 12, the dust sensor 13 and other structures are stably installed on the wall.

[0025] During long-term use, even in windy weather or when the wall is subjected to certain vibrations, the equipment will not loosen or fall off, ensuring the continuity and accuracy of the monitoring data.

[0026] Example 2: At a temporary construction site, there is a brick wall that is temporarily built and is expected to be demolished after a period of use. However, dust monitoring is required during this period, and the possibility of using equipment on other fixed walls for a long time in the future should also be taken into consideration.

[0027] For temporary brick walls, the wall mounting plate 7 is made of lightweight aluminum alloy and is fixed with short expansion bolts, making it easy to disassemble the equipment when the wall is removed.

[0028] Furthermore, when using the device, the fixed base 1 is fixed to the ground through the four through holes on the top and the anchor bolts are used. The top of the telescopic support rod 8 is slid into the mounting groove 10 of the rotating frame 6 and the two are locked by the screw 17 passing through the through hole 14. The support column 9 is inserted into the rotating frame 6 and the screw 2 16 passes through the corresponding through hole 2 15 to fix it, so that the control box 2 is kept horizontal, and the ground deployment is completed.

[0029] Disconnect the telescopic support rod 8 from the rotating frame 6, remove screw 17 and screw 2 16, then rotate the rotating frame 6. Subsequently, use screw 2 16 to fix the rotated rotating frame 6. Use the wall mounting plates 7 on both sides of the rotating frame 6 to fix the rotating frame 6 to the wall with expansion bolts.

[0030] After the equipment is started, the dust sensor 13 on the mounting bracket 5 and the noise detector 11 collect data synchronously. Both signals are transmitted to the processor inside the control box 2. The processor presets a dust concentration threshold (e.g., PM10 ≥ 0.5 mg / m³). 3 When dust exceeds the limit and noise exceeds the limit simultaneously, the control box 2 triggers the buzzer alarm 3 to emit a high-frequency warning sound, and the alarm light 4 strengthens the alarm in red flashing mode (frequency 2Hz) when dust exceeds the limit and noise exceeds the limit. If only a single parameter exceeds the limit (such as dust exceeding the limit but noise is normal), the alarm intensity is reduced (the buzzer sounds intermittently and the alarm light flashes yellow).

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
