Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction environmental protection equipment technology, and in particular to an intelligent spraying device. Background Technology
[0002] Dust pollution is a core challenge for environmental regulation in open-air operations such as construction and mining. According to data from the "China Environmental Statistics Yearbook," in 2022, construction dust emissions accounted for 18.7% of total particulate matter pollution nationwide. Furthermore, PM10 concentrations around construction sites often exceed national standards by 3 to 5 times, easily triggering respiratory diseases and exacerbating smog. Construction site dust pollution is a difficult aspect of environmental governance. Traditional sprinkler systems are mostly timed or manually controlled, unable to correlate with actual dust concentrations, resulting in response lag. Additionally, current sprinkler systems often have fixed spray ranges, unable to dynamically adjust the spray area, leading to insufficient coverage. Moreover, they lack intelligent improvements and cannot be integrated with smart construction site platforms for management, limiting their use. Therefore, we propose an intelligent sprinkler system to address these issues. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing traditional spray systems, which are mostly timed or manually controlled, cannot be correlated with actual dust concentration, and have a delayed response. Therefore, an intelligent spray device is proposed.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An intelligent sprinkler device includes a ring-shaped sprinkler pipe with a water pump at one end. Multiple dust detection sensors (PM10 and PM2.5) are mounted on the sprinkler pipe, with a threshold of 150 µg / m³ triggering an alarm. Multiple water outlet pipes are located at the bottom of the sprinkler pipes, with a sphere rotating horizontally with the liquid flow at the bottom of each outlet pipe. The sphere has a water inlet at its top and an atomizing nozzle at its bottom. The angle between the central axis of the atomizing nozzle and the central axis of the water outlet pipes is 10°-20°. The rotation of the sphere drives the atomizing nozzle to rotate, thereby increasing the spraying range.
[0006] Preferably, a rotating shaft is mounted inside the water outlet pipe via a mounting bracket. The rotating shaft is coaxial with the water outlet pipe, and an impeller is fixed on the rotating shaft. The bottom end of the rotating shaft is fixed to the sphere. The impeller rotates due to the flow of liquid, which in turn drives the sphere to rotate, without the need for a separate power device.
[0007] Preferably, a guide plate is provided on the side of the top of the water outlet pipe away from the direction of liquid flow. The guide plate is fixed to the inner wall of the spray pipe and guides the liquid into the water outlet pipe, thereby improving the stability of the impeller rotation.
[0008] Preferably, the guide plate is inclined, and the angle between the guide plate and the inner wall of the spray pipe is 45°-60° to improve the guiding effect.
[0009] Preferably, the sphere is hollow inside and has two to ten water inlets located inside the water outlet pipe. Liquid enters the sphere through the water inlets and is then sprayed out through the atomizing nozzle.
[0010] Preferably, it also includes a spray linkage mechanism. When the dust detection sensor detects that the dust level has reached a threshold, the spray linkage mechanism controls the water pump and atomizing nozzles to open for dust suppression.
[0011] The beneficial effects of this utility model are as follows:
[0012] Compared with existing technologies, this utility model uses a dust detection sensor to detect the concentration of dust. When the concentration reaches a preset threshold, the water pump is turned on to atomize the nozzles to reduce dust at the construction site. This avoids manual operation, improves the timeliness of dust reduction, and realizes intelligent dust reduction. At the same time, during the water flow in the spray pipe, the water flow drives the impeller to rotate, which in turn drives the atomizing nozzles to rotate, expanding their spraying range and reducing spray dead zones.

[0017] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0018] Reference Figure 1-3 A smart sprinkler device includes a ring-shaped sprinkler pipe 1, a water pump 2 at one end of the sprinkler pipe 1, and multiple dust detection sensors 3 installed on the sprinkler pipe 1. The dust detection sensors 3 are of PM10 and PM2.5 type, and the threshold is set to trigger an alarm when the value exceeds 150 µg / m³.
[0019] The bottom of the spray pipe 1 is provided with multiple water outlet pipes 4. The bottom end of the water outlet pipe 4 is equipped with a ball 41 that rotates horizontally with the flow of liquid. The inside of the water outlet pipe 4 is rotatably mounted with a mounting bracket 44. The rotating shaft 45 is coaxial with the water outlet pipe 4, and an impeller 46 is fixed on the rotating shaft 45. The bottom end of the rotating shaft 45 is fixed to the ball 41. The flow of liquid drives the impeller 46 to rotate, which in turn drives the ball 41 to rotate. No additional power device is required.
[0020] The top of the sphere 41 has a water inlet hole 43, and the bottom of the sphere 41 is provided with an atomizing nozzle 42. The angle between the central axis of the atomizing nozzle 42 and the central axis of the water outlet pipe 4 is 10°-20°. The rotation of the sphere 41 drives the atomizing nozzle 42 to rotate, thereby increasing the spraying range. The sphere 41 is hollow inside, and the number of water inlets 43 is two to ten. The water inlets 43 are located inside the water outlet pipe 4. The liquid enters the sphere 41 through the water inlets 43 and is then sprayed out through the atomizing nozzle 42.
[0021] Furthermore, a guide plate 5 is provided on the side of the water outlet pipe 4 away from the direction of liquid flow. The guide plate 5 is fixed to the inner wall of the spray pipe 1. The guide plate 5 is inclined and the angle between the guide plate 5 and the inner wall of the spray pipe 1 is 45°-60°, which improves the guiding effect. The liquid is guided into the water outlet pipe 4 through the guide plate 5, which improves the stability of the impeller 46 rotation.
[0022] This device also includes a spray linkage. When the dust detection sensor 3 detects that the dust level has reached the threshold, the spray linkage controls the water pump 2 and the atomizing nozzle 42 to open for dust suppression.
[0023] In this embodiment, during use, the dust detection sensor 3 detects dust in the working environment. When the threshold is reached, the water pump 2 draws external water into the spray pipe 1, which is then sprayed out by the atomizing nozzle 42 to reduce dust. During the water flow, the impeller 46 rotates, which in turn drives the ball 41 and the atomizing nozzle 42 to rotate, expanding the spray range and improving the dust reduction effect. At the same time, the dust detection sensor 3 avoids the need for manual control of the opening and closing of the atomizing nozzle 42, improving the timeliness of dust reduction.
[0024] In addition, the system can be equipped with an intelligent controller to achieve automatic control, which is convenient to operate, intelligently reduces dust, and saves labor. It also has manual and automatic switching functions to ensure safe and continuous operation of the equipment in the event of a control system failure. In addition to dust reduction, the system can also cool the construction site and, in the event of a fire, increase the water volume by adjusting the sprinkler system to assist in fire fighting. It has multiple protection functions such as short circuit, overcurrent, overvoltage, overheating, and overload protection.
[0025] As needed, the system is equipped with a self-testing program. If a fault occurs during system operation, it will automatically stop working and output an alarm. It has functions such as self-testing, fault diagnosis, fault memory, and fault prompting.
