Description

Air dust detection device

Technical Field

The utility model relates to the technical field of dust detection, in particular to an air dust detection device.

Background Art

The dust detector is an online monitoring system that measures the concentration of particulate matter and the level of noise in the surrounding environment based on light scattering counting and sound sensing technology. It is mainly used for construction sites. The dust detector is based on the Internet of Things and artificial intelligence technology. It collects and transmits data from detection sensors in various environments (PM2.5, PM10, noise, wind speed, wind direction, etc.) in real time. It displays hundreds of data in real time on the on-site LED screen, platform PC and mobile terminal according to demand, which is convenient for regulators to remotely monitor the real-time environmental data on site and make timely decisions.

During the construction process, construction sites need to use fog cannons and other equipment to reduce dust to prevent dust from affecting the surrounding environment or residents, and use dust detection devices for real-time detection to play a supervisory role. The structure of the existing dust detection device can be found in Figure 1. During use, some problems were found: in order to reduce the use of water and electricity, some construction sites only turned on the fog cannon equipment around the dust detection device during construction, so that the PM2.5 value displayed by the dust detection device was at a lower level, while other areas where dust detection devices were not set up would have less fog cannons, use low-power fog cannons, or even not turn on fog cannons. In this case, remote supervisors cannot know the specific situation of the construction site. Considering the cost issue, it is difficult to arrange multiple sets of dust detection devices at the construction site, which makes remote supervisors easily deceived by data.

The utility model is further described below in conjunction with the accompanying drawings:

As shown in Figures 2 to 5, an air dust detection device includes a load-bearing rod 1, on which an electric control cabinet 2 and a display screen 3 are respectively installed, and a wind direction sensor 4 and a wind speed sensor 5 are also installed on the top of the load-bearing rod 1. The display screen 3, the wind direction sensor 4 and the wind speed sensor 5 are all electrically connected to the electric control cabinet 2. The above are all in the prior art and will not be repeated here;

The electric control cabinet 2 is also electrically connected to a number of dust detection mechanisms 6, and the dust detection mechanisms 6 can be connected to the electric control cabinet 2 by wire or wireless connection. As shown in Figures 3 and 4, the dust detection mechanism 6 includes a base plate 61 connected to an external connector, and the base plate 61 can be connected to a bottom surface, a wall surface or other connectors. The base plate 61 is provided with a countersunk hole 611 to hide the nut of the bolt; a hidden plate 62 is bolted to the base plate 61, and the hidden plate 62 is used to hide the bolts of the base plate 61 to prevent others from dismantling the entire dust detection mechanism 6 together with the base plate 61; a load-bearing cylinder 63 is installed on the upper surface of the hidden plate 62, and an anti-dismantling mechanism 64 is provided in the load-bearing cylinder 63 to prevent others from privately dismantling and moving the position of the dust detection mechanism 6, and a louver box 65 is installed on the top of the load-bearing cylinder 63, and a dust sensor 66 for detecting dust is installed in the louver box 65. The louver box 65 and the dust sensor 66 are both prior art, and the utility model has not improved them, so they will not be repeated again.

As shown in FIGS. 3 to 5 , the anti-disassembly mechanism 64 includes a hollow sleeve 642 installed inside the load-bearing cylinder 63, a slider 643 is slidably mounted inside the hollow sleeve 642, a spring 645 is installed above the inside of the hollow sleeve 642, and the spring 645 is located above the slider 643. By setting the spring 645, the slider 643 is always located at the bottom of the hollow sleeve 642 when it is not subject to external force. A conductive sheet 644 is installed at the bottom of the slider 643 and the bottom surface of the hollow sleeve 642, and the conductive sheet 644 is connected to an alarm device (not shown in the figure). The alarm device can be an audible and visual alarm device, or a signal transmitting module, which alerts remote supervisors by transmitting an alarm signal. It can also be a combination of the two. When the two conductive sheets 644 are in contact, a circuit is formed and the alarm device is triggered. An insulating partition 646 that can slide in the horizontal direction is provided on the side of the hollow sleeve 642. When the insulating partition 646 is stuck between the two conductive sheets 644, the alarm device can be prevented from being triggered. A support shaft 641 is installed at the center of the upper surface of the base plate 61. A through hole is provided at the bottom of the hollow sleeve 642 for the support shaft 641 to pass through. When the hidden plate 62 is installed on the base plate 61, the support shaft 641 will slide up to disconnect the alarm device. A hinged plate 631 is hinged on one side of the load-bearing tube 63 close to the insulating partition 646. A door lock is installed on the hinged plate 631, and the key of the door lock is managed by the supervisor.

Working principle: When in use, the dust detection mechanisms 6 are dispersedly arranged on the construction site, the shutter box 65 and the load-bearing tube 63 are first assembled, and then the bottom plate 61 is fixed by bolts. After the bottom plate 61 is fixed, the hidden plate 62 is fixed to the bottom plate 61 by bolts to complete the installation of the dust detection mechanism 6.

During dismantling, the supervisor opens the hinged plate 631 with a key, presses the insulating partition 646 so that the insulating partition 646 is stuck between the two conductive sheets 644, and then removes the hidden plate 62 and the bottom plate 61 respectively. Due to the setting of the insulating partition 646, the two conductive sheets 644 can be prevented from contacting, thereby avoiding triggering the alarm device.

If someone dismantles the mobile dust detection mechanism 6 without permission, they can only remove the bolts on the hidden plate 62 first. After the bolts of the hidden plate 62 are removed, the load-bearing tube 63 and other components are removed. At this time, the spring 645 is no longer squeezed by the support shaft 641. The spring 645 pushes the slider 643 to make the two conductive sheets 644 contact, and the circuit of the alarm device is connected, triggering the alarm device.

The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
