Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment for building construction, and more specifically, to a dust suppression device for building construction. Background Technology

[0002] During the construction process, dust is always an important factor affecting environmental quality and the health of construction workers. From the large amount of soil being turned over during earthwork excavation, to the scattering of materials such as sand, gravel and cement during material handling, and the flying of particles during concrete mixing, a large amount of dust is generated. A search revealed an existing patent (publication number: CN222151415U) disclosing a dust control device for construction. The technology includes a water storage tank with a horizontally fixed partition dividing it into upper and lower sections. The upper section of the tank contains a negative pressure mechanism to create negative pressure in the lower section. The tank has a water inlet for injecting water into the lower section, a drain hole at the bottom, and a first cap sealing the drain hole. A suction port is located on the outside of the tank, connected to the lower section via a first connecting pipe. This design creates negative pressure in the lower section, drawing dust into it through the suction port. This facilitates dust collection, prevents dirt buildup on the floor, and makes construction easier. The first cap and drain hole allow for easy drainage of water and dust, making cleaning convenient.

[0003] In existing dust suppression devices for construction, fixed nozzles can only spray water mist in a fixed direction, and their effective coverage area is relatively small, making it difficult to cover the entire site. At the same time, the patent documents cited above do not propose any solutions to address the above problems. Therefore, a dust suppression device for construction is proposed to address the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust suppression device for construction, comprising a movable base, a bearing plate at the upper end of the movable base, a drive motor at the bottom of the bearing plate, a connecting pipe connected to one side of the drive motor via an output shaft, atomizing nozzles evenly spaced outside the connecting pipe, and a dust concentration sensor fixedly installed at the middle position of the front end of the connecting pipe.

[0006] Preferably, the connecting pipe is D-shaped and has a guide groove at the bottom, and the upper end of the bearing plate is symmetrically provided with fixing blocks, which are slidably connected to the guide groove.

[0011] Preferably, a water storage tank is fixedly installed at the bottom of the fixed pipe, and a water level monitoring sensor is installed on one side of the water storage tank.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this dust suppression device for construction uses an atomizing nozzle that rotates electrically. Combined with real-time regional concentration monitoring by a dust concentration sensor, the sensor can accurately capture the differences in dust concentration in different directions. The controller drives the atomizing nozzle to rotate directionally to the high-concentration area based on the sensor data, ultimately achieving no dead angle coverage of the construction area.

[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. Example 1

[0019] As attached Figures 1 to 4 The dust suppression device for construction is shown, including a movable base 1, a support plate 2 at the upper end of the movable base 1, a drive motor 3 at the bottom of the support plate 2, a connecting pipe 5 connected to one side of the drive motor 3 through an output shaft 4, atomizing nozzles 6 evenly spaced outside the connecting pipe 5, and a dust concentration sensor 7 fixedly installed at the middle position of the front end of the connecting pipe 5.

[0020] Among them, by setting up a dust concentration sensor 7, real-time regional concentration monitoring can be realized, and the sensor can accurately capture the difference in dust concentration in different directions. The controller drives the atomizing nozzle 6 to rotate directionally to the high concentration area based on the sensor data. Example 2

[0021] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the connecting pipe 5 is D-shaped and has a guide groove 8 at the bottom, and the upper end of the support plate 2 is symmetrically provided with fixing blocks 9, which are slidably connected to the guide groove 8; furthermore, by providing fixing blocks 9, the guide groove 8 slides along the fixing blocks 9, which restricts the radial displacement of the connecting pipe 5, prevents the connecting pipe 5 from shaking or deviating when rotating, and ensures that the spraying direction of the atomizing nozzle 6 is accurate.

[0022] In a preferred embodiment, a fixed pipe 22 is provided on one side of the connecting pipe 5, a high-pressure pump 10 is provided on one side of the fixed pipe 22, and a telescopic pipe 11 is provided on one side of the fixed pipe 22; furthermore, by providing the telescopic pipe 11, it can flexibly extend and retract with the rotation of the connecting pipe 5 without affecting the water flow, and at the same time avoids damage to the pipeline due to rotation and pulling.

[0023] In a preferred embodiment, a fixing rod 12 is provided between the connecting pipes 5, a dust extraction fan 13 is provided on one side of the fixing rod 12, and a threaded sleeve 14 is provided on one side of the dust extraction fan 13; furthermore, by providing the threaded sleeve 14, the dust extraction fan 13 is connected to the output pipe 15, which facilitates disassembly and maintenance in the future.

[0024] In a preferred embodiment, an output pipe 15 is threadedly connected to one side of the threaded sleeve 14, and a filter 16 is provided on one side of the output pipe 15; furthermore, by providing the filter 16, dust particles are intercepted, air purification is achieved, secondary diffusion of fine dust is avoided, and the purified air is directly discharged.

[0025] In a preferred embodiment, a hydraulic cylinder 17 is provided on one side of the upper end of the movable seat 1, and a hydraulic rod 18 is sleeved on one side of the hydraulic cylinder 17. The hydraulic rod 18 is fixedly connected to the support plate 2 on one side. Telescopic rods 19 are symmetrically and fixedly provided at both ends of the bottom of the support plate 2. Furthermore, by providing the hydraulic cylinder 17, the hydraulic cylinder 17 drives the hydraulic rod 18 to extend and retract, thereby driving the support plate 2 to rise and fall as a whole, thereby adjusting the height of the atomizing nozzle 6 to ensure that the water mist can cover the dust diffusion area.

[0026] As a preferred embodiment, a water storage tank 20 is fixedly installed at the bottom of the fixed pipe 22, and a water level monitoring sensor 21 is installed on one side of the water storage tank 20; furthermore, by installing the water level monitoring sensor 21, the water level in the tank is monitored in real time, and when the water level is lower than a preset threshold, a low water level signal is sent to the controller to avoid the sprinkler system from shutting down due to lack of water.

[0027] The working process of this utility model is as follows: First, the dust concentration sensor 7 is fixed at the middle of the front end of the D-shaped connecting pipe 5. It can rotate with the connecting pipe 5 to achieve full-area scanning and collect dust concentration data from different directions. After the sensor converts the concentration signal into an electrical signal, it transmits it to the controller in real time. The water level monitoring sensor 21 is installed on one side of the water storage tank 20 to continuously monitor the water level in the tank. When the water level is lower than the preset threshold, the sensor sends a low water level signal to the controller, which then triggers an alarm to prevent the sprinkler system from shutting down due to water shortage. When the controller detects that the dust concentration in a certain direction exceeds the standard, it sends a rotation command to the drive motor 3 at the bottom of the support plate 2. The drive motor 3 drives the D-shaped connecting pipe 5 to rotate through the output shaft 4. At the same time, the guide groove 8 at the bottom of the connecting pipe 5 slides with the fixing block 9 at the top of the support plate 2 to ensure that the connecting pipe 5 is stable and does not deviate during rotation. When the controller detects that the dust concentration is highest on the north side, the drive motor 3 drives the connecting pipe 5 to rotate to the north side. On the north side, the atomizing nozzle 6 is precisely aimed at the high-concentration area. The controller adjusts the output power of the high-pressure pump 10 according to the dust concentration level. The high-pressure pump 10 delivers water from the water storage tank 20 to the connecting pipe 5 through the fixed pipe 22 and the telescopic pipe 11. The water is then atomized into fine water mist by the atomizing nozzle 6, increasing the contact area with the dust. The telescopic pipe 11 can rotate and deform flexibly with the connecting pipe 5 without affecting the water flow. When it is necessary to adapt to dust sources of different heights, the controller sends a telescopic command to the hydraulic cylinder 17. The hydraulic cylinder 17 pushes the hydraulic rod 18 to extend and retract, driving the entire support plate 2 to rise and fall. At the same time, the telescopic rod 19 at the bottom of the support plate 2 extends and retracts synchronously to ensure the horizontal stability of the support plate 2 during the lifting and lowering process. When dealing with dust from material piles at high places, the hydraulic rod 18 extends to push the support plate 2 upward, raising the height of the atomizing nozzle 6 to ensure that the water mist covers the dust diffusion area. For fine dust particles, the controller simultaneously starts the dust suction fan 13 on one side of the fixed rod 12. The vacuum cleaner 13 generates negative pressure, drawing in dust-laden air from the surrounding environment through the inlet. The air is then transported to the filter 16 via the output pipe 15 connected to the threaded sleeve 14, separating dust from the air. Water pressurized by the high-pressure pump 10 is atomized and sprayed out through the atomizing nozzle 6 on the D-shaped connecting pipe 5. The water mist collides with and adsorbs dust particles in the air, eventually causing them to settle to the ground. The dust-laden air drawn in by the vacuum cleaner 13 enters the filter 16, where the filter screen intercepts dust particles. The purified air is then directly discharged, avoiding secondary pollution. The output pipe 15 is threadedly connected to the threaded sleeve 14, facilitating periodic disassembly of the filter 16 for filter screen replacement or cleaning.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
