Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an automatic sprinkler device for monitoring dust concentration during building construction. Background Technology

[0002] During construction, earthwork excavation, material transportation, concrete mixing and other operations generate a large amount of dust. This dust not only contains particulate matter such as PM2.5 and PM10, but may also adsorb harmful substances such as heavy metals and volatile organic compounds, seriously polluting the construction site and the surrounding atmospheric environment. According to statistics, construction dust accounts for more than 30% of urban dust pollution sources. It not only causes construction workers to be exposed to high dust environments for a long time, increasing the risk of occupational health diseases such as respiratory diseases and pneumoconiosis, but also affects the living environment of surrounding residents.

[0003] Spraying dust suppression devices are a common means of controlling dust in construction. They spray fine water mist onto dusty areas, using the combination of water droplets and dust particles to cause dust to settle, thereby effectively reducing the concentration of dust in the air. Automatic spraying devices, by integrating dust concentration monitoring functions, can automatically trigger spraying actions based on real-time monitoring data, and have advantages such as timely response, high dust suppression efficiency, and saving manpower.

[0004] Traditional sprinkler heads are mostly fixed installations, covering a fixed area, which makes it difficult to adapt to the dynamic changes in dust sources at the construction site (such as alternating construction in different work areas). In addition, the atomized particles are relatively large, resulting in low binding efficiency with dust particles and incomplete dust suppression. To solve this problem, we propose an automatic sprinkler device for monitoring dust concentration in construction sites. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic sprinkler system for monitoring dust concentration during construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic sprinkler device for monitoring construction dust concentration includes a support mechanism, which is fixed to the construction site fence. A mounting frame is fixed to the top of the support mechanism, and a motor is mounted on the side of the mounting frame. The output shaft of the motor is inserted into the interior of the mounting frame and connected to a movable seat. A sprinkler mechanism is mounted on the top of the movable seat.

[0008] The spraying mechanism includes a housing fixed on a movable base, a liquid distribution pipe fixed inside the housing, both ends of the liquid distribution pipe penetrating through both sides of the housing, a spray nozzle mounted on the side of the liquid distribution pipe, a fixing plate mounted on the side of the housing, a sleeve fixed inside the fixing plate, and a fan mounted inside the sleeve.

[0009] Preferably, the support mechanism includes a support frame, a threaded sleeve is installed on the side of the support frame, the threaded sleeve is inserted into the interior of the support frame, an adjusting rod is threadedly connected to the interior of the threaded sleeve, the adjusting rod is inserted into the interior of the support frame and rotatably connected to a movable plate, the movable plate is slidably connected to the support frame, and buffer pads are fixed on the inner wall of the support frame and the side of the movable plate.

[0010] Preferably, the inner walls of the movable plate and the support frame cooperate to install the support mechanism on the building fence.

[0011] Preferably, guide shafts are fixed at both ends of the side of the movable plate, and the guide shafts pass through the side of the support frame and are slidably connected to it.

[0012] Preferably, there are two guide shafts, which are parallel to the adjusting rod and are located between the two guide shafts.

[0013] Preferably, both ends of the dispensing pipe are connected to the supply pipe, and the number of nozzles is several groups.

[0014] Preferably, the number of fixed plates is at least three, and the fan introduces external air and blows air out of the housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The support mechanism of this utility model achieves rapid adaptation to building fences of different thicknesses through an adjustable mechanical structure. Specifically, the movable plate inside the support frame can achieve horizontal displacement through the threaded transmission of the adjusting rod and the threaded sleeve. With the sliding guidance of the guide shafts on both sides, the movable plate and the inner wall of the support frame form an adjustable clamping space, which can closely fit various fence structures. The buffer pad not only avoids scratches on the fence surface during installation, but also enhances the stability of the device under wind force through elastic buffering.

[0017] The linkage design of the mounting bracket, motor and movable seat gives the spraying mechanism dynamic adjustment capability: the motor drives the movable seat to rotate through the output shaft, which drives the spraying mechanism to adjust the spray angle in real time, which can achieve directional coverage for dynamic dust sources and expand the coverage range compared with traditional fixed nozzles. The liquid distribution pipe inside the spraying mechanism works with multiple sets of nozzles to form a spray array, while the fan in the sleeve further atomizes the water mist and blows it out through forced airflow, ensuring that the water mist accurately reaches the dust area.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 An automatic sprinkler device for monitoring dust concentration during construction includes a support mechanism 1, which is fixed to the fence of the construction site. A mounting frame 2 is fixed to the top of the support mechanism 1, and a motor 3 is installed on the side of the mounting frame 2. The output shaft of the motor 3 is inserted into the interior of the mounting frame 2 and connected to a movable seat 4. A sprinkler mechanism 5 is installed on the top of the movable seat 4.

[0024] As one implementation method, refer to Figure 1 and Figure 3 The spraying mechanism 5 achieves dynamic dust suppression through the linkage design of the mounting frame 2, motor 3, and movable seat 4: the mounting frame 2 is fixed to the top of the support mechanism 1, the output shaft of the motor 3 passes through the mounting frame 2 and is rigidly connected to the movable seat 4. After being powered on, it can drive the movable seat 4 to rotate the spraying mechanism 5, so that the spray array formed by the liquid distribution pipe 52 and multiple sets of nozzles 53 in the housing 51 can adjust the spray angle in real time, accurately cover the dynamic dust source, and completely solve the problem of blind spots in the coverage of traditional fixed nozzles. The fixed sleeve 55 is fixed on the fixed plate 54 on the side of the housing 51. When the internal fan 56 is running, it converts the external air into a high-speed airflow, which on the one hand refines the water mist sprayed by the nozzles 53 and enhances the binding efficiency with dust particles, and on the other hand forms a directional thrust to expand the water mist coverage radius. The two ends of the liquid distribution pipe 52 are connected to the liquid supply pipe to ensure that the water flow is evenly distributed to each nozzle 53. With the airflow push of the fan 56, the dust suppression efficiency and water resource utilization rate are improved.

[0025] As one implementation method, refer to Figure 1 and Figure 2The support mechanism 1 achieves efficient adaptation and stable installation of fencing of different thicknesses through an adjustable mechanical structure: the threaded sleeve 12 on the side of the support frame 11 and the adjusting rod 13 form a threaded transmission structure. When the adjusting rod 13 is rotated, the movable plate 14 can be driven to slide horizontally on the inner wall of the support frame 11. The guide shafts 15 on both sides pass through the support frame 11 and guide synchronously, so that the movable plate 14 and the inner wall of the support frame 11 form an adjustable clamping space, which can closely fit various fencing structures. The buffer pads 16 on the inner wall of the support frame 11 and the side of the movable plate 14 fill the installation gap through elastic deformation, which not only avoids scratches on the fencing surface, but also offsets the vibration caused by wind, enhancing the wind resistance stability of the device. This structure does not require disassembly of parts or use of additional tools. Installation can be completed by rotating the adjusting rod 13, which significantly improves the versatility and deployment efficiency of the device in different construction sites.

[0026] The installation of the support mechanism 1 achieves fence adaptation through mechanical transmission: the inner wall of the support frame 11 is attached to the outer side of the fence, and the adjusting rod 13 is rotated to move axially through the threaded sleeve 12. The adjusting rod 13 drives the movable plate 14 to slide on the inner wall of the support frame 11. The guide shafts 15 on both sides pass through the support frame 11 simultaneously to guide the fence, so that the movable plate 14 and the inner wall of the support frame 11 clamp the fence. The buffer pad 16 fills the gap to avoid scratching the fence and to offset vibration. Different thickness fences can be adapted by rotating the adjusting rod 13 without disassembling the parts.

[0027] Mounting bracket 2 is fixed to the top of support mechanism 1. The output shaft of motor 3 drives movable seat 4 to rotate, which in turn drives spray mechanism 5 to rotate. Inside housing 51 of spray mechanism 5, liquid distribution pipe 52 is connected to liquid supply pipe, and multiple sets of nozzles 53 spray out initial water mist. When the fan 56 inside sleeve 55 on fixed plate 54 is running, it draws in air and forms airflow, pushing water mist in a designated direction. When the position of dust source changes, motor 3 adjusts the angle of movable seat 4 so that nozzle 53 is aligned with dust area. The airflow of fan 56 refines water mist and expands coverage area to achieve dynamic dust suppression.

[0028] In summary, this utility model achieves efficient dust reduction through a support mechanism and a spraying mechanism. In the support mechanism, the threaded transmission of the adjusting rod and the threaded sleeve drives the movable plate to slide horizontally. With the guidance of the guide shaft, the movable plate and the inner wall of the support frame can be quickly installed and stably fixed with barriers of different thicknesses. The spraying mechanism drives the movable seat to rotate through a motor, which drives the housing to adjust the spray angle. The liquid distribution pipe and multiple sets of nozzles form a spray array. When the fan is running, the airflow blows out to refine the water mist and push it in a direction, accurately covering the dynamic dust source.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
