Description

Technical Field

[0001] This invention relates to the field of dust control, specifically to a device and method for controlling dust generated during construction. Background Technology

[0002] During construction, earthmoving, demolition, concrete pumping, and other construction activities disturb the ground and generate a large amount of dust. The fine particulate matter in the dust has a serious impact on air quality and may cause respiratory diseases, especially posing a greater risk to residents and workers around the construction site. In addition, laws and regulations in many places require construction companies to take measures to control dust in order to avoid environmental pollution and legal liability.

[0003] Current technologies mostly use fog cannons to treat dust. The principle is that the fog cannon guides water mist through airflow, spraying the water mist onto the dusty area so that the water mist can absorb the dust. However, in this process, the effective spray range of a single fog cannon is limited, making it difficult to effectively control dust. While multiple fog cannons can ensure that water mist is sprayed evenly over a larger area, thereby effectively controlling dust, the simultaneous operation of multiple fog cannons not only increases energy consumption and dust control costs, but also increases the difficulty of deployment and the labor intensity of workers.

[0004] Furthermore, the dust levels at some construction sites are beyond the reach of fog cannons. Therefore, existing technologies, in order to deal with this dust, have spent a lot of money to purchase high-power fog cannons, but their application scenarios are limited. This not only further increases operating costs but also wastes water resources. Nowadays, with the widespread adoption of automation technology, in order to achieve multiple spray dust suppression effects with one device, current dust suppression equipment has installed multiple sets of electrically controlled valves at the water supply point of the spray. Although these valves can automatically control the water flow, the harsh environment of construction sites makes it easy for many valves to be damaged. Therefore, a more durable, automated, and intelligent dust control device is needed to overcome the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a construction dust control device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction dust control device and method, comprising a mobile vehicle body and a turntable assembly mounted on top of the mobile vehicle body, and further comprising a spray bar assembly, a high-pressure control assembly, and a balancing assembly mounted on the turntable assembly. The spray bar assembly can be lifted from the turntable assembly, and the balancing assembly is installed opposite to the spray bar assembly. The spray bar assembly is composed of multiple hollow rods, with the two sides of the hollow rods facing the mobile vehicle body and away from the mobile vehicle body serving as spray surfaces. The high-pressure control assembly includes a fixed disk and a rotating disk A, which, when rotated, enables the two spray surfaces of the hollow rods to spray separately and simultaneously.

[0007] Preferably, a water-dividing plate is fixedly installed at the middle position of each hollow rod, dividing the interior of the hollow rod into two closed cavities. All hollow rods are connected end to end, and the corresponding closed cavities are interconnected. A top sprayer is installed at the top of the uppermost hollow rod, and two sets of side sprayers and two sets of side water sprayers are provided on both sides of the hollow rod. The side sprayers and side water sprayers on one side are connected to the interior of the closed cavity. The two closed cavities of the lowermost hollow rod are respectively connected to the fixed plate by a water pump pipe A.

[0008] Preferably, the side sprayers and side water sprayers are arranged in a straight line at equal intervals, and the side sprayers and side water sprayers are arranged alternately.

[0009] Preferably, the fixed disk has two vertically penetrating water outlet holes A and two vertically penetrating water inlet holes. The pump pipe A is connected to the water outlet holes A. The rotating disk A covers the lower end of the fixed disk and is rotatably connected to it in a sealed manner. The bottom end of the rotating disk A has a hollow cavity structure. The rotating disk A has two arc-shaped grooves communicating with the bottom cavity. The rotating disk A also has four water outlet holes B communicating with the bottom cavity. The rotating disk A also has water outlet holes C communicating with the bottom cavity. When the rotating disk A rotates, any one water inlet hole always corresponds to one arc-shaped groove, the two water outlet holes A can correspond to two of the water outlet holes B, and the water outlet hole C corresponds to only one water outlet hole A.

[0010] Preferably, the turntable assembly includes a rotating disk B and a hydraulic cylinder. The rotating disk B has a ring-shaped structure, and a fixed disk is fixedly installed at the bottom center of the rotating disk B. The rotating disk B is installed above the mobile vehicle body and is rotatably connected to the mobile vehicle body by bearings. It also includes a motor A, which is fixed to the mobile vehicle body and is used to drive the rotating disk B to rotate. The lowest hollow rod is hinged to the rotating disk B, and one end of the hydraulic cylinder is hinged to the rotating disk B, while the other end is hinged to the hollow rod.

[0011] Preferably, the balancing assembly includes a water tank and a support. The support is fixed to the rotating disk B, and the water tank is fixedly installed on the end of the support away from the rotating disk B and is installed opposite to the hydraulic cylinder. Two water pump pipes B are installed at the bottom of the water tank, and the other end of the water pump pipes B is connected to the water inlet.

[0012] Preferably, the high-voltage control component further includes a motor B, which is fixed on the rotating disk B and is used to drive the rotating disk A to rotate.

[0013] Preferably, the mobile vehicle body includes a vehicle body and four sets of track assemblies mounted on the vehicle body.

[0014] A method for controlling construction dust includes the following steps:

[0015] S1: First, the water tank is connected to the water supply pipeline, and the four sets of track components are controlled to move the vehicle body to the location where dust suppression is required.

[0016] S2: Combine and install multiple hollow rods, and control the extension of the hydraulic cylinder to raise the multiple hollow rods and create an angle;

[0017] S3: Control motor B to rotate so that water outlet C corresponds to a single water outlet A, thereby causing the hollow rod to spray water droplets and water mist towards the side sprayer on one side of the vehicle body;

[0018] S4: Adjust the side of the water spray on the hollow rod according to the height of the dust, to achieve downward spraying, upward spraying, or double-sided spraying.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The construction dust control device and method utilizes a high-pressure control component to control the rotation of the rotating disk A relative to the fixed disk. This allows for the adjustment of the water spray pattern on the hollow rod's downward or upward sides, or both sides of the hollow rod to be sprayed with water. Consequently, the dust suppression state can be continuously adjusted based on the height and area of ​​the dust, and the water flow can be increased or decreased in a timely manner according to the dust situation. This eliminates the need for complex electrical control valves to control the water circuit, resulting in greater durability and water conservation.

[0021] 2. The construction dust control device and method are equipped with a turntable assembly and a mobile vehicle. The hollow rods can rotate or swing up and down, thereby changing the spray pattern and spray surface according to the dust conditions. Combined with the mobile vehicle, it can reach deep into the dust-generating point under remote control or intelligent control to autonomously suppress dust, achieving a more intelligent dust suppression effect.

[0022] 3. The construction dust control device and method are equipped with a spray bar assembly. The hollow bars can be assembled and the height can be changed. The strong supporting force of the hydraulic cylinder can support the long hollow bars and suppress a high amount of dust at one time. There is no need to purchase a higher power fog cannon. Under the same spray range, it saves more energy than the fog cannon of the existing technology.

[0023] 4. The construction dust control device and method, by setting up a balancing component, allows the water tank to store a certain amount of dust suppression water. Even when it is inconvenient to connect to the water system, it can still achieve water spraying to suppress dust. Therefore, it can reach the dust-generating locations on the construction site. When connected to the water system, it can play a certain role in balancing the vehicle body. Attached Figure Description

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0036] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0037] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0039] like Figures 1-10As shown, a construction dust control device includes a mobile vehicle body 1 and a turntable assembly 2 mounted on the mobile vehicle body 1. It also includes a spray bar assembly 3, a high-pressure control assembly 4, and a balancing assembly 5 mounted on the turntable assembly 2. The spray bar assembly 3 can be lifted from the turntable assembly 2, and the balancing assembly 5 is installed opposite to the spray bar assembly 3. The spray bar assembly 3 is composed of multiple hollow rods 301, with the two sides of the hollow rods 301 facing the mobile vehicle body 1 and away from the mobile vehicle body 1 serving as spray surfaces. The high-pressure control assembly 4 includes a fixed disk 401 and a rotating disk A402. When the rotating disk A402 rotates, it enables the two spray surfaces of the hollow rods 301 to spray separately and simultaneously.

[0040] In construction, spray-type dust control devices are a highly efficient and flexible dust suppression technology. They primarily use water mist to adsorb airborne dust particles, achieving dust reduction. Currently, the main types of spray-type dust control devices include: perimeter spray systems, tower crane spray systems, mobile fog cannons, and scaffolding spray systems. Mobile fog cannons atomize water into 30-200 micrometer particles, which are then sprayed remotely by a fan (range 20-100 meters). They offer advantages such as flexibility and targeted application, making them suitable for instantaneous dust control during earthwork excavation and waste transportation. They are applicable to earthwork operation areas, stockpiles, loading and unloading points, etc., hence the widespread use of mobile fog cannons on construction sites. This application differs from existing technologies in that it does not use a fog cannon to blow water mist; instead, it utilizes a spray boom assembly 3 to increase the head and reduce power consumption.

[0041] When not in use, the spray bar assembly 3 is detached and folded onto the mobile vehicle 1 for easy transport and relocation. When needed, it can be assembled and installed according to the actual conditions of the construction site, and the height of the assembly can be customized.

[0042] like Figures 4-9 As shown, in an optional embodiment, a water-dividing plate 302 is fixedly installed at the middle position of each hollow rod 301. The water-dividing plate 302 divides the interior of the hollow rod 301 into two closed cavities 303. All hollow rods 301 are connected end to end, and the corresponding closed cavities 303 are interconnected. A top sprayer 304 is installed at the top of the uppermost hollow rod 301. Two sets of side sprayers 305 and two sets of side water sprayers 306 are provided on both sides of the hollow rod 301. The side sprayers 305 and side water sprayers 306 on one side are connected to the interior of the closed cavity 303. The two closed cavities 303 of the lowermost hollow rod 301 are connected to the fixed plate 401 by water pump pipes A307.

[0043] In this embodiment, each hollow rod 301 is provided with a water distribution plate 302 inside. The diameter of the hollow rod 301 varies with the installation height. The diameter of the lower hollow rod 301 is always larger than that of the other hollow rod 301 installed above it. Therefore, the closed cavity 303 of the lower hollow rod 301 is always connected to the closed cavity 303 of the upper hollow rod 301.

[0044] The two adjacent hollow rods 301 are connected by flanges, which provides strong sealing.

[0045] The top sprayer 304 is always installed on the top of the uppermost hollow rod 301. Under the action of high-pressure water flow, the water is sprayed in the form of a water mist.

[0046] The side sprayer 305 sprays water in the form of a water mist under the action of high-pressure water flow.

[0047] The side water sprayer 306 sprays water in the form of droplets under the action of high-pressure water flow.

[0048] Pump pipe A307 is used to transmit high-pressure water flow.

[0049] like Figure 5 As shown, in an optional embodiment, the side sprayers 305 and the side water sprayers 306 are arranged in a straight line at equal intervals, and the side sprayers 305 and the side water sprayers 306 are arranged alternately.

[0050] In this embodiment, the side sprayers 305 and 306 of the staggered mine clearance system produce water mist mixed with water droplets during actual water supply. Therefore, during dust suppression, the water mist can agglomerate particulate dust, while the water droplets can further cause the dust to settle. Compared with the traditional single water mist effect, the water mist mixed with water droplets has a better effect. In actual use, under the same time, the water mist mixed with water droplets causes the dust to settle faster.

[0051] like Figures 6-10 As shown, in an optional embodiment, the fixed disk 401 is provided with two vertically penetrating water outlet holes A403 and two vertically penetrating water inlet holes 404. The pump pipe A307 is connected to the water outlet holes A403. The rotating disk A402 covers the lower end of the fixed disk 401 and is rotatably connected to it in a sealed manner. The bottom end of the rotating disk A402 has a hollow structure. The rotating disk A402 is provided with two arc-shaped grooves 405 communicating with the bottom cavity. The rotating disk A402 is also provided with four water outlet holes B406 communicating with the bottom cavity. The rotating disk A402 is also provided with a water outlet hole C407 communicating with the bottom cavity. When the rotating disk A402 rotates, any one water inlet hole 404 always corresponds to one arc-shaped groove 405, the two water outlet holes A403 can correspond to two of the water outlet holes B406, and the water outlet hole C407 corresponds to only one water outlet hole A403.

[0052] In this embodiment, a sealing ring is fixedly installed on the upper end of the rotating disk A402, and a bearing is installed at the connection between the sealing ring and the fixed disk 401. The sealing ring and the bearing can seal the air while achieving relative rotation, so there will be no leakage when water enters the cavity at the bottom of the rotating disk A402 from above.

[0053] Regardless of how the rotating disk A402 rotates, at least one water inlet 404 corresponds to the arc-shaped groove 405 to ensure a continuous water supply.

[0054] The four water outlets B406 are arranged in a 90-degree circular array around the center of the rotating disk A402, and the two water outlets A403 are arranged in a 180-degree array, with the water outlets A403 and B406 on the same motion path.

[0055] The water outlet C407 is also on the above path, but there is no other corresponding water outlet C407, so it can only correspond to a single water outlet A403.

[0056] like Figures 3-8 As shown, in an optional embodiment, the turntable assembly 2 includes a rotating disk B201 and a hydraulic cylinder 202. The rotating disk B201 has an annular structure, and a fixed disk 401 is fixedly installed at the bottom center of the rotating disk B201. The rotating disk B201 is installed above the mobile vehicle body 1 and is rotatably connected to the mobile vehicle body 1 by bearings. It also includes a motor A203, which is fixed on the mobile vehicle body 1 and is used to drive the rotating disk B201 to rotate. The lowest hollow rod 301 is hinged to the rotating disk B201, and one end of the hydraulic cylinder 202 is hinged to the rotating disk B201, and the other end is hinged to the hollow rod 301.

[0057] In this embodiment, a gear ring is installed on the rotating disk B201, and a gear is installed on the output shaft of the motor A203. The gear meshes with the gear ring for transmission, and the hydraulic cylinder 202 can fold or lift the hollow rod 301.

[0058] like Figures 6-7 As shown, in an optional embodiment, the balancing assembly 5 includes a water tank 501 and a bracket 502. The bracket 502 is fixed to the rotating disk B201. The water tank 501 is fixedly installed on the end of the bracket 502 away from the rotating disk B201 and is installed opposite to the hydraulic cylinder 202. Two pump pipes B503 are installed at the bottom of the water tank 501, and the other end of the pump pipes B503 is connected to the water inlet 404.

[0059] In this embodiment, the bracket 502 extends the water tank 501. A pump is installed inside the water tank 501 to pump high-pressure water into the pump pipe B503. A water supply pipe is installed on the water tank 501 to connect with the water supply pipe and keep the water level in the water tank 501 constant.

[0060] like Figure 7 As shown, in an optional embodiment, the high-voltage control component 4 further includes a motor B408, which is fixed on the rotating disk B201 and is used to drive the rotating disk A402 to rotate.

[0061] In this embodiment, a gear ring is installed on the rotating disk B201, and a gear is also installed on the output shaft of the motor B408 to mesh with the gear ring.

[0062] like Figures 1-3 As shown, in an optional embodiment, the mobile vehicle body 1 includes a body 101 and four sets of track assemblies 102 mounted on the body 101.

[0063] In this embodiment, all four track assemblies 102 can be controlled individually, thus enabling the vehicle body 101 to turn and make a U-turn.

[0064] The vehicle body integrates multi-parameter sensors to monitor PM2.5, PM10, noise, temperature, humidity, wind speed, and other data in real time, uploading the data to a cloud platform via 4G / 5G. Exceeding these limits triggers an automatic alarm and activates dust suppression equipment. It dynamically adjusts spray intensity based on AI algorithms (e.g., automatically starting and stopping based on dust concentration and weather conditions). Remote APP / PC control is supported, enabling unmanned operation. It has its own power system, either electric or fuel-powered, allowing for autonomous movement or path planning (e.g., with SLAM navigation technology). Key technologies include an Internet of Things (IoT) architecture: sensors → edge computing → cloud data analysis → feedback control, forming a closed-loop management system. AI image recognition: cameras identify dust sources (e.g., dump truck unloading) for targeted spraying, saving water resources. Big data analysis: historical data accumulation predicts peak dust periods, optimizing construction schedules.

[0065] like Figures 1-10 As shown, a method for controlling construction dust includes the following steps:

[0066] S1: First, the water tank 501 is connected to the water supply pipeline, and the four sets of track components 102 are controlled to move the vehicle body 101 to the location where dust suppression is required.

[0067] S2: Assemble multiple hollow rods 301 and control the hydraulic cylinder 202 to extend, so that the multiple hollow rods 301 are raised and have an angle;

[0068] S3: Control motor B408 to rotate so that water outlet C407 corresponds to a single water outlet A403, thereby causing hollow rod 301 to spray water droplets towards the side water sprayer 306 and side sprayer 305 spray water mist towards the side of vehicle body 101.

[0069] S4: Adjust one side of the water spray on the hollow rod 301 according to the height of the dust, to achieve downward spraying, upward spraying or double-sided spraying.
