Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an intelligent dust suppression system for construction sites. Background Technology

[0002] Construction site dust pollution has become one of the major sources of urban air pollution, posing a threat to the occupational health of construction workers and severely reducing the quality of life for nearby residents. Currently, dust control at construction sites mainly relies on a combination of traditional manual monitoring and water spraying, but this approach has significant limitations in practical application. Manual monitoring struggles to achieve continuous, 24 / 7 dust concentration monitoring, making it difficult to detect and address dust exceeding standards in a timely manner. Meanwhile, traditional water spraying measures, lacking a precise concentration feedback mechanism, often fail to dynamically adjust operational parameters based on actual dust conditions, resulting in water waste and difficulty in ensuring stable dust suppression effects.

[0003] More importantly, existing dust control systems generally lack intelligent data analysis and dynamic optimization capabilities. In the complex and ever-changing construction environment of building sites, this static management model struggles to achieve precise environmental adaptation. Furthermore, traditional dust suppression equipment heavily relies on manual operation, increasing labor costs and leading to high maintenance costs due to high equipment failure rates. Although emerging technologies such as the Internet of Things, big data, and artificial intelligence have brought new possibilities to the field of environmental governance in recent years, intelligent solutions for dust control at construction sites are still in their infancy. In particular, key technological bottlenecks remain to be overcome in areas such as high-precision dust monitoring, automated equipment control, intelligent early warning systems, and dynamic optimization algorithms.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1.

[0021] like Figure 1 As shown, the present invention provides an intelligent dust suppression system for construction sites, including a dust suppression device 1 installed at a location on the construction site where dust is easily generated, a PLC controller 2 connected to the dust suppression device 1, a PM10 sensor 3 and a TSP sensor 6 installed at a location on the construction site where dust is easily generated and respectively connected to the PLC controller 2, and an early warning mechanism installed in the monitoring room of the construction site and connected to the PLC controller 2.

[0022] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It integrates monitoring sensors and dust suppression equipment through a PLC controller, thereby enabling real-time monitoring of dust information at construction sites where dust is prone to occur. When the monitored data exceeds the standard value stored in the PLC controller, the dust suppression equipment at the location where dust exceeds the standard will be controlled to operate. The PLC controller can also control the intensity of the dust suppression equipment operation based on the monitored dust information to achieve the purpose of rapid and efficient dust suppression.

[0023] This utility model also includes an early warning mechanism. When the dust in the dust-generating condition has not been reduced to the environmental protection requirements within the specified time, the PLC controller 2 controls the early warning mechanism to issue an early warning. After receiving the early warning, the dust reduction personnel will go to the site in real time to check and supervise the dust reduction work. For example, they can check whether the dust reduction equipment 1 is faulty and needs to be repaired. If the dust reduction equipment 1 is not faulty, the management will mobilize more dust reduction equipment to participate in the dust reduction operation.

[0024] The preferred PLC controller used in this invention is the Siemens S7-1200 PLC controller.

[0025] Example 2.

[0026] like Figure 1 As shown, the present invention provides an intelligent dust suppression system for construction sites, including a dust suppression device 1 installed at a location on the construction site where dust is easily generated, a PLC controller 2 connected to the dust suppression device 1, a PM10 sensor 3 and a TSP sensor 6 installed at a location on the construction site where dust is easily generated and respectively connected to the PLC controller 2, and an early warning mechanism installed in the monitoring room of the construction site and connected to the PLC controller 2.

[0027] The PLC controller 2 is connected to an anemometer 4, which is located at a construction site where dust is likely to be generated.

[0028] Based on Example 1, this embodiment 2 presents a more optimized structure for the intelligent dust suppression system at construction sites. Specifically, the PLC controller 2 is connected to an anemometer 4 located at a dust-prone area of ​​the construction site. The anemometer 4 can monitor the wind speed at the dust-prone area in real time. After receiving the wind speed information data, the PLC controller 2 can more effectively control the operation of the dust suppression equipment 1, controlling the dust suppression intensity of the dust suppression equipment 1 based on the wind speed information data, and amplifying the dust suppression effect of the dust suppression equipment 1 by leveraging the wind speed.

[0033] Based on Example 2, this embodiment 3 presents a more optimized structure for the intelligent dust suppression system at construction sites. Specifically, the PLC controller 2 is connected to a photoelectric wind vane 5 located at a dust-prone area of ​​the construction site. The photoelectric wind vane 5 can monitor the wind direction at the dust-prone area in real time. After receiving the wind direction information data, the PLC controller 2 can more effectively control the operation of the dust suppression equipment 1. The dust suppression equipment 1 at the wind outlet can increase the dust suppression intensity to achieve a better dust suppression effect.

[0036] The early warning system includes a PC 8 connected to the PLC controller 2 and an audible and visual alarm 7 connected to the PC 8.

[0037] Based on Example 1, this embodiment 4 provides a more preferred structure for the early warning mechanism. Specifically, the early warning mechanism includes a PC 8 connected to the PLC controller 2 and an audible and visual alarm 7 connected to the PC 8. The PC 8 is preferably a programmable logic controller (PLC). The PLC controller 2 transmits information received from the PM10 sensor 3, TSP sensor 6, anemometer 4, and photoelectric wind vane 5 to the PC 8 in real time. The PC 8 stores the received information (cyclic storage, retaining data from a period prior to the current moment). When the PLC controller 2 receives abnormal information, such as when dust levels do not significantly decrease after a specified time following the activation of dust suppression equipment, it transmits the abnormal information to the PC 8. Upon receiving the abnormal information, the PC 8 controls the audible and visual alarm 7 to issue an early warning. Upon receiving the warning from the audible and visual alarm 7, dust suppression personnel promptly take special measures to eliminate environmental hazards related to dust.

[0041] Based on Example 1, this embodiment 5 presents a more optimized structure for an intelligent dust suppression system at construction sites. Specifically, the PLC controller 2 is connected to an LCD control screen 10. Dust suppression personnel can interact with the PLC controller 2 through the LCD control screen 10, issuing control commands to control the operation of the dust suppression equipment. This is simple and efficient, eliminating the need for on-site command during dusty conditions.

Furthermore, for the same dusty conditions, only one of the above-mentioned dust suppression systems can be set up, or multiple dust suppression systems can be set up simultaneously, freely selected according to the dust intensity and type of the construction site.

[0046] Example 7.

[0047] like Figure 1 As shown, the present invention provides an intelligent dust suppression system for construction sites, including a dust suppression device 1 installed at a location on the construction site where dust is easily generated, a PLC controller 2 connected to the dust suppression device 1, a PM10 sensor 3 and a TSP sensor 6 installed at a location on the construction site where dust is easily generated and respectively connected to the PLC controller 2, and an early warning mechanism installed in the monitoring room of the construction site and connected to the PLC controller 2.

[0048] The dust suppression equipment 1 includes one or more of the following: a perimeter spray system, a 360° spray system, a water sprinkler dust suppression system, and an external scaffolding sprinkler system. The PLC controller 2 is connected to the electric drive equipment of the perimeter spray system, the 360° spray system, the water sprinkler dust suppression system, or the external scaffolding sprinkler system.

[0049] The water supply tank of the enclosure spray system, 360° spray system, water sprinkler dust suppression system or external scaffolding sprinkler system is equipped with a level gauge 9 connected to the PLC controller 2.

[0050] Based on Example 6, this embodiment 7 provides a more preferred structure for the dust suppression equipment 1. Specifically, the water supply tank of the enclosure spray system, 360° spray system, water spraying dust suppression system, or external scaffolding sprinkler system is equipped with a level gauge 9 connected to the PLC controller 2. All of the above-mentioned dust suppression equipment 1 has a water supply tank for storing water, and the dust suppression water mist used for dust suppression spraying and sprinkler systems originates from the water source in the water supply tank. The level gauge 9 transmits the water level information in the water supply tank to the PLC controller 2 in real time. When the water level in a certain tank is insufficient, the PLC controller 2 transmits the information to the PC 8. The PC 8 displays the water level of the insufficient tank and controls the audible and visual alarm 7 to issue a warning. After receiving the warning, the management personnel manage the replenishment of water in the corresponding water supply tank in real time to prevent dust pollution hazards caused by untimely dust suppression and damage to the dust suppression equipment 1 due to idle load. The low water level warning sound and warning light color can be different from the warning sound and warning light color of the above-mentioned dust suppression non-compliance, to facilitate timely management instructions.

[0053] The PLC controller 2 is connected to an industrial gateway 11, which is connected to a 4G / 5G communication chip 12. The 4G / 5G communication chip 12 is wirelessly connected to the dust control administrator's mobile phone 13.

[0054] Based on Example 1, this embodiment 8 presents a more optimized structure for the intelligent dust suppression system at construction sites. Specifically, the PLC controller 2 is connected to an industrial gateway 11, which in turn is connected to a 4G / 5G communication chip 12. The 4G / 5G communication chip 12 is wirelessly connected to the dust suppression administrator's mobile phone 13. Upon receiving abnormal information such as substandard dust suppression or insufficient water level in the water tank, the PLC controller 2 also pushes information to the dust suppression administrator's mobile phone 13 in real time via the industrial gateway 11 and the 4G / 5G communication chip 12, such as SMS or APP notifications. This allows the administrator to make timely dust suppression arrangements even when not in the monitoring room, preventing potential environmental hazards.

[0055] This invention aims to provide an intelligent dust control system for construction sites. By integrating high-precision sensors and the Internet of Things (IoT), it achieves real-time monitoring, precise control, intelligent early warning, and dynamic optimization of dust pollution at construction sites.
