[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, building construction refers to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. During construction, a large amount of dust is generated, and the flying dust will affect the progress of construction. Therefore, dust control devices are required.

[0003] For example, the utility model disclosed in CN222641581U discloses a dust control device for construction engineering. By setting a torsion spring, a protrusion and a pin, the torsion spring can apply force to the support block, causing the support block to abut against the inner wall behind the protrusion. At this time, the two sets of horizontal pipes are placed horizontally. During the dust suppression process of moving the device, if the horizontal pipe impacts a foreign object, due to the setting of the rotating rod and the torsion spring, the horizontal pipe is subjected to force and adaptively retracts towards the box. This structure can avoid damage caused by hard impact. The horizontal pipe is of fixed length, the coverage of the nozzle is limited, it is difficult to deal with large-area or high-altitude dust, the dust suppression efficiency is insufficient, and the equipment position needs to be adjusted frequently.

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a dust control device for construction engineering, including a mobile spraying device 1. The mobile spraying device 1 includes a fixed base 11, a water tank 14, a lifting frame 15, a water pump 16, and a water spraying assembly 17. The water tank 14 is fixedly installed on the upper surface of the fixed base 11, the lifting frame 15 is fixedly installed on one side of the fixed base 11, the water pump 16 is fixedly installed at the bottom of the lifting frame 15, and the water spraying assembly 17 is rotatably installed on the upper surface of the lifting frame 15. A support assembly 2 is fixedly installed in the middle of the upper surface of the fixed base 11. The support assembly 2 includes a fixed seat 26, and a dust suction assembly 3 is fixedly installed on the upper part of the fixed seat 26.

[0020] The fixed base 11 of the mobile spraying device 1 serves as the basic support for the device, providing stability and ensuring that the equipment is not easily tipped over during movement or operation. It can also integrate auxiliary components such as power supply and control modules. The water tank 14 stores the water required for dust suppression; its capacity is designed according to the operation duration and range, and it must be airtight to prevent leakage. The lifting frame 15 raises the height of the water spraying assembly 17, expanding the spray coverage area, especially for low-to-medium altitude dust. The water pump 16 pressurizes the water in the water tank 14 and delivers it to the water spraying assembly 17, ensuring spray distance and atomization effect to meet the dust suppression needs of different dust concentrations. The water spraying assembly 17 can be rotated or has an adjustable angle. The nozzles, with their varying angles, enable multi-directional spraying, covering the area around the device and quickly settling dust particles in the air. The mounting base 26 of the support component 2 serves as the installation foundation for the dust collection component 3, providing stable support and potentially integrating height adjustment or angle rotation functions to adapt to different operating scenarios. The dust collection component 3 targets dust near the ground or around the equipment, collecting it into the filter or dust collection box through negative pressure adsorption, reducing secondary dust generation. It is especially suitable for enclosed spaces or areas with high local dust concentrations. The water spray component 17 covers a large area, while the dust collection component 3 targets local high-concentration dust, forming a "surface-point" combined dust suppression system to improve efficiency.

[0021] Workflow: Confirm that the water level in water tank 14 is sufficient, and that the water pump 16, water spray assembly 17, and dust collection assembly 3 are properly connected without leaks or blockages. Move the equipment to the vicinity of the dust source, ensuring that the spraying range covers the main dust-generating area. Adjust the pressure of water pump 16, the angle of water spray assembly 17, and the suction of dust collection assembly 3 according to the dust concentration. Turn on water pump 16, and water is delivered to water spray assembly 17 via the lifting frame 15, forming an atomized water curtain to settle dust. Simultaneously turn on dust collection assembly 3 to adsorb and collect dust near the ground or around the equipment. Optimize the dust reduction effect by rotating water spray assembly 17 or moving the device according to the dust diffusion situation. For post-operation maintenance, turn off dust collection assembly 3 and water pump 16 in sequence, and drain the remaining water from water tank 14. The combination of spraying and dust collection covers dust of different heights and concentrations, reducing the limitations of a single method. The lifting frame 15 and the fixed base 26 support the height adjustment of water spray assembly 17 and dust collection assembly 3 to adapt to different construction scenarios.

[0022] The support assembly 2 includes a rectangular frame 21, a triangular support frame 22, an extension rod 23, a hinge seat 24, and a fixing rod 25. The bottom end of the rectangular frame 21 is bolted to the upper surface of the fixed base 11. The triangular support frame 22 is bolted to the middle of the rectangular frame 21. One end of the extension rod 23 is fixedly installed at one end of the rectangular frame 21. The hinge seat 24 is bolted to the other end of the extension rod 23. One end of the fixing rod 25 is rotatably installed with the hinge seat 24. One side of the fixing rod 25 is fixedly installed with the dust collection assembly 3. The fixing seat 26 is bolted to the top of the rectangular frame 21.

[0023] The rectangular frame 21 serves as the main frame of the support assembly 2. It is bolted to the fixed base 11, providing stable vertical support and ensuring the load of the vacuum assembly 3 and extension rod 23 is transferred to the foundation. An installation interface for the fixed seat 26 is reserved at the top, and a triangular support frame 22 is installed in the middle to achieve a layered layout of the vacuuming system and spraying system, avoiding interference. The triangular support frame 22 is bolted to the middle of the rectangular frame 21, forming a stable triangular structure that effectively disperses the vibration and torque generated during the operation of the vacuum assembly 3, preventing the rectangular frame 21 from bending or deforming due to long-term stress. Compared to a solid support, the triangular structure reduces material usage and lowers the overall weight of the equipment while maintaining strength. The extension rod 23 is fixed to the rectangular frame 21. 1. The working range of the dust collection component 3 is extended to the side to avoid overlapping with the spraying area of ​​the water spray component 17 and improve space utilization. The hinge seat 24 is rotatably connected to the fixed rod 25, so that the dust collection component 3 can rotate ±45° around the vertical axis to adapt to dust sources in different directions. One side of the fixed rod 25 is connected to the dust collection component 3, and the other end is linked to the extension rod 23 through the hinge seat 24 to ensure the positional stability of the dust collection component 3 in the horizontal direction. The fixed seat 26 is bolted to the top of the rectangular frame 21 to limit the dust collection component 3 for a second time to prevent it from vertical displacement due to vibration or collision. The extension rod 23 increases the working radius of the dust collection component 3 by 1.5-2 times. The angle adjustment function of the hinge seat 24 ensures that the dust suction port is always facing the dust source.

[0024] The vacuuming assembly 3 includes a vacuum cleaner 31, a vacuum hose 32, and a vacuum port box 33. The vacuum cleaner 31 is vertically and fixedly installed on the top of the mounting base 26. One end of the vacuum hose 32 is inserted into the suction end of the vacuum cleaner 31. The vacuum port box 33 is fixedly installed on the other end of the vacuum hose 32. One side of the vacuum port box 33 is bolted to the fixing rod 25.

[0025] The vacuum cleaner 31 uses a centrifugal fan, which generates continuous negative pressure through high-speed rotation to ensure sufficient suction at the suction port 33, effectively capturing PM2.5 to PM10 dust particles. A built-in cyclone separator separates the sucked-in dust from the air; the dust falls into the dust collection box, while clean air is discharged through the exhaust port, reducing secondary dust. Vertical installation is advantageous as it is fixed to the top of the mounting base 26, using gravity to help dust settle to the bottom of the dust collection box, preventing dust accumulation and clogging of the air duct when horizontally installed. The suction hose 32 is a retractable corrugated hose, connected to the suction end of the vacuum cleaner 31 via a snap-fit ​​connector, allowing for quick assembly and disassembly within 10 seconds, facilitating cleaning blockages or hose replacement. The suction port 33 features a trapezoidal wide-mouth structure, expanding the suction coverage and reducing missed areas, making it particularly suitable for large dusty surfaces. It is connected to the fixing rod 25 with bolts to ensure the suction port 33 remains stable during equipment movement or vacuuming, preventing a decrease in suction efficiency due to vibration.

[0026] An inverted U-shaped mounting base 231 is fixedly installed in the middle of the extension rod 23, and an installation collar 321 is sleeved in the middle of the suction pipe 32. The installation collar 321 is bolted to the inverted U-shaped mounting base 231.

[0027] The inverted U-shaped mounting base 231 is integrally formed from high-strength alloy steel. The two side ears of the inverted U-shaped mounting base 231 are bolted to the extension rod 23. The top wall has reserved M12 bolt holes with the hole spacing matching the mounting ring 321. As a fixed support point for the suction pipe 32, it rigidly connects the middle part of the suction pipe 32 to the extension rod 23, preventing the suction pipe 32 from swinging due to airflow impact or equipment vibration during the suction process, and preventing the suction port box 33 from deviating from the dust source.

[0028] A battery assembly 12 is fixedly installed in the middle of the bottom wall of the fixed base 11. The battery assembly 12 is electrically connected to the water pump 16 and the vacuum cleaner 31. Casters 13 are rotatably installed on both sides of the battery assembly 12.

[0029] The fixed base 11 adopts a Q235B carbon steel welded frame, which can bear the weight of the battery pack 12, water pump 16, and vacuum cleaner 31. A groove is set in the middle of the bottom wall for embedded installation of the battery pack 12. The battery pack 12 is a modular integration of the power supply core. The battery pack is fixed in the groove of the base with bolts to prevent the battery pack from loosening when the equipment moves. One universal wheel and two fixed wheels are installed on each side of the battery pack 12 to take into account both steering flexibility and straight driving stability.

[0030] A water pump 16 is equipped with a water pump pipe 161 at one end and a drain pipe 162 is fixedly installed at the other end of the water pump 16. The drain pipe 162 is connected to the top of the water spray assembly 17. The water spray assembly 17 includes a rotating U-shaped mounting base 171, a blower 172 and a water spray pipe 173. The rotating U-shaped mounting base 171 is rotatably mounted on the upper surface of the lifting frame 15. The blower 172 is fixedly mounted inside the rotating U-shaped mounting base 171. The water spray pipe 173 is annularly mounted on the top of the blower 172.

[0031] The water pump 16 is a centrifugal water pump, suitable for dust suppression needs at construction sites. It is fixed to the upper surface of the fixed base 11 with four M12 bolts. The water pipe 161 is a PVC steel wire reinforced hose. One end is connected to the water inlet of the water pump 16 through a pagoda connector, and the other end is equipped with a float valve to automatically control the water level. The drain pipe 162 is a galvanized steel pipe, which is connected to the water outlet of the water pump 16 through a flange. The drain pipe 162 extends vertically upward along the side wall of the fixed base 11 and then connects horizontally to the top of the water spray assembly 17 through an elbow to reduce fluid resistance. The water spray assembly 17 has a rotating U-shaped mounting base 171 with a multi-angle adjustable support structure. The bottom is connected to the upper surface of the lifting frame 15 through a rotating shaft. The blower 172 enhances dust suppression with airflow assistance. It has a built-in axial flow fan. The impeller is driven by a motor to rotate, which guides the airflow to the water mist sprayed from the water spray pipe 173, increasing the diffusion range of the water mist under the action of the airflow.
