A dust suppression device for construction projects

Abstract

This utility model discloses a dust suppression device for construction engineering, belonging to the field of construction engineering technology. Its key technical features include a base plate with a support rod welded to the middle of the top of the base plate, and a top plate welded to the top of the support rod. This application, by setting up a dust suppression mechanism, allows a bidirectional lead screw and two side sliders to flexibly drive the fans and atomizing structures at their respective tops, adjusting the lateral distance between the two sets of fans and atomizing structures to effectively expand the coverage area. A stepper motor drives an angle-adjusting structure, enabling precise horizontal deflection of the fans and atomizing structures. This not only adapts to different dust sources and avoids dust suppression blind spots but also allows for flexible switching of operating modes, such as concentrated dust suppression in one area or directional operation. Simultaneously, the angle-adjusting structure can precisely adjust the spray angle of the fans and atomizing structures, solving the problem of inconvenient traditional adjustments. The atomizing structure and fans work together to allow water vapor to diffuse efficiently with the help of wind, further eliminating blind spots and improving dust suppression efficiency.

Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a dust suppression device for building engineering. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Construction engineering is closely related to people's production and life, and its construction quality and safety are directly related to social harmony and stability. During construction, activities such as earthwork excavation, concrete mixing, and material handling generate a large amount of dust, which not only pollutes the environment but also endangers the health of construction workers. Therefore, it is necessary to control dust diffusion through dust suppression devices to ensure the safety of the construction environment and protect the surrounding air quality.

[0003] Dust suppression devices used in construction projects are subject to impurities in the water source due to the working environment. Prolonged use can affect the lifespan of the water pump and atomizing nozzles, resulting in a decrease in dust suppression effect and hindering widespread use. Furthermore, the height and spraying angle of the atomizing nozzles cannot be adjusted according to the user's needs, leading to inconvenience in use. An existing patent (publication number: CN222943177U) discloses a dust suppression device for construction engineering. This utility model uses a filter frame to filter and intercept impurities in the water flow. At the same time, the flow guide base allows the filtered impurities to be fully discharged through the drain port, thus preventing residue. Furthermore, since the filter frame is snapped between the water storage tank and the fixed cover, the filter frame can be cleaned and maintained by opening the fixed cover during use. This allows for full utilization of existing water sources and facilitates widespread use.

[0004] To address the aforementioned issues, existing patents offer solutions, but current dust suppression devices for construction projects suffer from several drawbacks. Firstly, their coverage is limited; the spray structure is relatively fixed and often a single unit, with limited directional and angle adjustments, making it difficult to adapt to different dust sources and easily creating dust suppression blind spots. Secondly, angle adjustment is inconvenient, often relying on fixed or manual adjustment modes with low precision, failing to accurately adjust for dust diffusion directions and exhibiting poor adaptability in complex construction environments. Thirdly, their level of intelligence is low, with water supply and spray start / stop relying on manual operation, unable to be controlled by a controller, easily leading to resource waste. Furthermore, the low integration of the spray structure, angle adjustment, direction adjustment, and air supply device prevents coordinated operation, resulting in overall inconvenience and limited dust suppression efficiency.

[0005] Therefore, a dust suppression device for construction engineering is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a dust suppression device for construction engineering, which can solve the problems of existing dust suppression devices for construction engineering, such as limited coverage, relatively fixed and mostly single-set spray structure, limited direction deflection and angle adjustment, difficulty in adapting to dust sources in different areas, easy to form dust suppression blind spots, inconvenient angle adjustment, mostly fixed or manual adjustment mode, low precision, unable to accurately adjust to the dust diffusion direction, poor adaptability in complex construction environments, low level of intelligence, water supply and spray start and stop rely on manual operation, unable to be controlled by a controller, which easily leads to resource waste. In addition, the integration of spray structure, angle adjustment, direction adjustment and air supply device is low, and collaborative operation is not possible, resulting in inconvenient overall operation and limited dust suppression efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A dust suppression device for construction engineering includes a base plate 1, a support rod 2 welded to the middle of the top of the base plate 1, a top plate 3 welded to the top of the support rod 2, a controller 4 arranged on the left side of the rear side of the top plate 3, and a dust suppression mechanism 5 arranged on the top of the top plate 3. The dust suppression mechanism 5 includes a chute 51 formed at the top of the top plate 3. A bidirectional lead screw 52 is rotatably connected inside the chute 51. The left side of the bidirectional lead screw 52 passes through the interior of the chute 51. A servo motor 53 is bolted to the left side of the top plate 3. The output end of the servo motor 53 is fixedly connected to the left side of the bidirectional lead screw 52. Slider 54s are threadedly connected to both sides of the surface of the bidirectional lead screw 52. The slider 54s are slidably connected inside the chute 51. A cavity sleeve 55 is welded to the top of the slider 54. A stepper motor 56 is installed inside the cavity sleeve 55. An angle adjustment structure 57 is fixedly connected to the output end of the stepper motor 56. A fan 58 is installed inside the angle adjustment structure 57. An atomizing structure 59 is installed on the front side of the fan 58.

[0020] In this embodiment: by setting up a base plate 1, support rod 2, top plate 3, controller 4 and dust suppression mechanism 5, during use, the base plate 1 provides stable support for the overall structure, the support rod 2 and the top plate 3 form an installation frame, after the controller 4 presets the operating parameters, it starts the servo motor 53 to drive the bidirectional lead screw 52 to rotate in the slide groove 51, driving the sliders 54 on both sides to slide synchronously in opposite directions along the slide groove 51, thereby adjusting the lateral spacing of the two sets of cavity sleeves 55, so that the top fan 58 and atomizing structure 59 can adapt to construction areas of different widths. Subsequently, the stepper motor 56 in the cavity sleeve 55 starts, and the angle adjustment structure 57 is activated. The fan 58 and atomizing structure 59 are driven to deflect horizontally, precisely targeting the dust source area. At the same time, the angle adjustment structure 57 can adjust the spray angle of the fan 58 and atomizing structure 59 to ensure that the coverage height and direction are matched. The operation of the fan 58 generates airflow, and the atomizing structure 59 sprays atomized water vapor simultaneously. The water vapor is diffused to the dust area by the wind to achieve dust suppression. Throughout the process, the controller 4 links and controls the servo motor 53 to adjust the spacing, the stepper motor 56 to adjust the angle, and the atomizing structure 59 to control the spray. The automated dust suppression operation can be completed without manual intervention, and the operation is smooth and efficient.

[0021] Specifically, such as Figure 3 As shown, the angle adjustment structure 57 includes a steering plate 571 fixedly connected to the output end of the stepper motor 56. Connecting rods 572 are welded to both sides of the top of the steering plate 571. The inner side of the connecting rods 572 is rotatably connected to the outer side of the fan 58.

[0022] Specifically, such as Figure 3 As shown, a fixing sleeve 573 is welded to the top of the steering plate 571, and a connecting sleeve 574 is welded to the bottom of the fan 58.

[0023] Specifically, such as Figure 3 As shown, an electric push rod 575 is rotatably connected inside the fixed sleeve 573. The telescopic end of the electric push rod 575 is rotatably connected inside the connecting sleeve 574. The electric push rod 575 is electrically connected to the controller 4.

[0024] In this embodiment: by setting the angle adjustment structure 57, when the stepper motor 56 drives the steering plate 571 to rotate, the connecting rod 572 drives the fan 58 to deflect horizontally in sync with the steering plate 571, thereby realizing the horizontal angle adjustment. When it is necessary to adjust the spray height of the fan 58, the controller 4 controls the extension and retraction of the electric push rod 575. One end of the electric push rod 575 rotates in the fixed sleeve 573, and the other end pushes the connecting sleeve 574 to drive the fan 58 to rotate around the connecting rod 572, thereby accurately changing the pitch angle between the fan 58 and the atomizing structure 59, adapting to dust sources of different heights, and improving the targeting of dust suppression.

[0025] Specifically, such as Figure 4As shown, the atomizing structure 59 includes an annular pipe 591 disposed inside the front side of the fan 58, and an atomizing nozzle 592 is uniformly connected to the front side of the annular pipe 591 along the circumference.

[0026] Specifically, such as Figure 4 As shown, the bottom of the ring pipe 591 is connected to a control valve 593, which is electrically connected to the controller 4. The bottom of the control valve 593 is connected to a three-way water supply pipe 594, which is connected to an external water supply channel.

[0027] In this embodiment: by setting the atomizing structure 59, after the three-way water supply pipe 594 is connected to the external water source, the controller 4 controls the control valve 593 to open according to the dust suppression requirements. The water flows through the ring pipe 591 and is distributed to each atomizing nozzle 592. The nozzles spray atomized water vapor evenly along the circumference of the ring pipe 591. The airflow generated by the fan 58 pushes the atomized water vapor to the dust area efficiently, increasing the contact area with the dust and improving the dust suppression efficiency. The control valve 593 can flexibly adjust the water supply to avoid water waste.

[0028] Specifically, such as Figure 5 As shown, self-locking casters 6 are bolted to the four corners of the bottom of the base plate 1, and placement frames 7 are fixedly connected to the front and rear sides of the top of the base plate 1. A counterweight 8 is set inside the placement frame 7.

[0029] Specifically, such as Figure 5 As shown, support structures 9 are provided on the front and rear sides of both sides of the base plate 1. The support structure 9 includes a pull plate 91 that is slidably connected to both sides of the base plate 1. The top of the pull plate 91 is threadedly connected to a support screw 92, and the bottom of the support screw 92 is welded to a grounding plate 93.

[0030] In this embodiment: by setting up self-locking casters 6, placement frame 7, counterweight 8 and support structure 9, the self-locking casters 6 facilitate the overall movement of the device to the designated construction area and prevent slippage after locking. The counterweight 8 in the placement frame 7 increases the stability of the device and prevents shaking when the fan 58 is running. During operation, pull out the pull plates 91 on both sides of the base plate 1 and rotate the support screw 92 to make the grounding plate 93 contact the ground and tighten it, further enhancing the support strength of the device on uneven ground and ensuring a stable and reliable dust reduction process.

[0031] Working Principle: In the process of using the dust suppression device in construction engineering, firstly, the device is moved to the construction area via the self-locking casters 6 at the bottom of the base plate 1. The casters 6 are locked to prevent slippage. Then, counterweights 8 are placed into the placement frame 7 to enhance overall stability. The pull plates 91 on both sides of the base plate 1 are pulled out, and the support screw 92 is rotated to make the contact plate 93 contact the ground and tighten, ensuring the device is stable and does not shake during operation. After power is connected, the controller 4 is powered on and enters the working state. The operator presets dust suppression parameters, such as coverage area and angle, through the controller 4. After starting the device, the controller 4 drives the servo motor 53 to rotate. The servo motor 53 drives the bidirectional lead screw 52 to rotate within the slide groove 51 of the top plate 3, causing the sliders 54 on both sides to slide synchronously in opposite directions along the slide groove 51, adjusting the lateral spacing of the two sets of cavity sleeves 55 to adapt to the width of the construction area. Subsequently, the stepper motor 56 inside the cavity sleeve 55 starts, driving the steering plate 571 to rotate, and the connecting rod 572 rotates accordingly. The guide plate 571 drives the fan 58 and the atomizing structure 59 to deflect horizontally, precisely aiming at the dust source area. If the spray height needs to be adjusted, the controller 4 controls the extension and retraction of the electric push rod 575. One end of the electric push rod 575 rotates in the fixed sleeve 573, and the other end pushes the connecting sleeve 574, causing the fan 58 to rotate around the connecting rod 572, achieving precise adjustment of the pitch angle. At the same time, the controller 4 controls the control valve 593 to open, and the external water source enters the ring pipe 591 through the three-way water supply pipe 594 and the control valve 593. Then, the atomized water vapor is evenly sprayed out through the atomizing nozzle 592 on the front side of the ring pipe 591. The airflow generated by the operation of the fan 58 efficiently pushes the atomized water vapor to the dust area to achieve dust suppression. Throughout the process, the controller 4 coordinates and controls the servo motor 53, the stepper motor 56, the electric push rod 575 and the control valve 593, and completes the automated dust suppression operation without manual intervention. After the operation is completed, the controller 4 shuts down all components and disconnects the power supply.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
