Description

Technical Field

[0001] This application relates to the field of spray device technology, and in particular to a municipal construction dust spray device. Background Technology

[0002] During municipal construction (such as road construction, pipeline laying, and building demolition), a large amount of dust is generated due to earthwork excavation, material transportation, and machinery operation. This dust mainly contains particulate matter such as PM2.5 and PM10, which not only pollutes air quality, reduces visibility in and around the construction area, and affects the ecological environment, but also harms human health. Long-term inhalation can cause respiratory and lung diseases, disrupt the lives of residents, and the dust adheres to the surfaces of buildings, vegetation, and vehicles, affecting the quality of life of residents and potentially causing neighborhood disputes.

[0003] The existing device separates the monitoring and spraying systems, resulting in a delayed response. Furthermore, timed spraying wastes water resources and has an unstable dust suppression effect, causing dust monitoring and spraying dust suppression to not be linked in real time, which fails to improve the level of intelligence and increases the consumption of manpower and resources.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

[0005] The purpose of this application is to provide a municipal construction dust suppression spraying device with the advantages of integrated monitoring and control, which solves the problems of delayed response caused by the separation of monitoring and spraying systems in existing devices, as well as the waste of water resources and unstable dust suppression effect caused by timed spraying.

[0006] The municipal construction dust spraying device provided in this application adopts the following technical solution: it includes a fixed base, an installation groove is formed on the upper surface of the fixed base, a caster wheel is fixedly installed on the bottom surface of the fixed base, an installation plate is slidably connected to the inner wall of the installation groove, a support plate is fixedly connected to the upper surface of the installation plate, a display screen is fixedly installed on the outer surface of the support plate, a laser scattering sensor and a temperature and humidity sensor are fixedly installed on the upper surface of the display screen, a housing is fixedly installed on the upper surface of the fixed base, a water collection tank is fixedly installed on the inner wall of the housing, a PLC controller is fixedly installed on the outer surface of the water collection tank, a connecting cable is fixedly installed on the outer surface of the PLC controller, and a relay group is fixedly installed at the end of the connecting cable away from the PLC controller.

[0007] By adopting the above technical solution, the fixed base serves as the foundation of the entire device, with its mounting groove slidably connected to the mounting plate. This design facilitates quick disassembly or adjustment of the support plate. The support plate and fixed base are then connected using fixing bolts. The casters provide mobility, allowing the device to adapt to the dispersed and dynamically changing dust sources in municipal construction. The laser scattering sensor is the core monitoring element; its principle is to calculate dust concentration by using laser light to irradiate airborne particles and utilizing the intensity of the scattered light. It offers high accuracy and can provide real-time feedback on the dust pollution level in the construction area. The temperature and humidity sensor serves as an auxiliary monitoring element, providing... Environmental temperature and humidity parameters are considered. Dust is more easily dispersed in high-temperature and dry environments. In this case, the PLC controller can use this data to increase the spraying frequency. In high-humidity environments, spraying may be reduced to avoid excessive moisture affecting construction. The display screen is not only a data display window, but may also have an operation interface function to improve the convenience of human-machine interaction. After receiving real-time data, the PLC controller will compare it with the preset threshold. When the dust concentration exceeds the standard, it will send a command to the relay group through the connection cable. The relay group is responsible for controlling the on and off of the subsequent spraying components. The water collection tank stores the spraying water, and the shell prevents the water tank from being hit by construction debris, rainwater pollution, etc.

[0008] Preferably, a pump is fixedly installed on the inner wall of the water collection tank, and the output end of the pump is fixedly connected to a first connecting pipe and a second connecting pipe.

[0009] By adopting the above technical solution, the pump is installed on the inner wall of the water collection tank and is the power source of the spray system. Its core function is to draw water stored in the water collection tank and provide sufficient water pressure to ensure that the water flow can be output through the first connecting pipe and the second connecting pipe to form an effective spray.

[0010] Preferably, a solenoid valve is fixedly installed on the outer surface of both the first connecting pipe and the second connecting pipe, and the outer surfaces of both the first connecting pipe and the second connecting pipe are fixedly connected to the water collection tank.

[0011] By adopting the above technical solution, the first connecting pipe and the second connecting pipe serve as water conveyance channels. They branch out from the pump output end, enabling multi-area or multi-mode spraying. By connecting different positions and different types of nozzles, the spraying coverage can be expanded to meet the dust suppression needs of larger construction areas, and the spraying mode can be adjusted according to the dust concentration.

[0012] Preferably, both the outer surfaces of the shell and the water collection tank are provided with water inlet grooves, and the inner walls of the two water inlet grooves are connected.

[0013] By adopting the above technical solution, water inlet grooves are opened on the outer surfaces of the shell and the water collection tank, and the inner walls of the two are connected to form a double-layer water inlet path from the outside of the device to the inside of the water collection tank. Construction personnel can directly add water to the water collection tank through the water inlet groove without opening the sealing structure of the shell or the water collection tank, making the operation more convenient. If an automatic water replenishment device is connected, the water inlet groove can also serve as a fixed interface to ensure the stability of the water replenishment process.

[0014] Preferably, a fixed frame is rotatably connected to the upper surface of the housing, a motor is fixedly installed on the outer surface of the fixed frame, and a connecting rod is fixedly connected to the output end of the motor.

[0015] By adopting the above technical solution, the fixed frame is rotatably connected to the upper surface of the shell, serving as the bearing base of the motor. It can rotate horizontally around the axis of the upper surface of the shell, thereby expanding the lateral coverage of the subsequent spraying components. The motor is fixed to the outer surface of the fixed frame, serving as a power source. The connecting rod connected to its output end can drive the connecting rod to rotate.

[0016] Preferably, the fixing frame is equipped with an atomizing cannon inside, and the outer surface of the atomizing cannon is fixedly connected to the connecting rod.

[0017] By adopting the above technical solution, the atomizing cannon is a highly efficient device for dust control. Its core function is to atomize water into fine particles under high pressure to form a large-scale mist-like water curtain. The water mist combines with dust particles in the air, causing them to settle, thereby quickly reducing the dust concentration. The fixed frame is rotatably connected to the upper surface of the shell, driving the atomizing cannon to rotate horizontally. Combined with pitch adjustment, it can achieve omnidirectional and multi-angle directional spraying, accurately covering the dust pollution source.

[0018] Preferably, the outer surface of the connecting rod is rotatably connected to the fixing frame, and the inner wall of the atomizing cannon is connected to the second connecting pipe.

[0019] By adopting the above technical solution, when the motor is working, the connecting rod can swing vertically with the connection point with the fixed frame as the axis, thereby driving the atomizing cannon to achieve precise adjustment of the pitch angle. The water in the water tank is pressurized by the pump and then directly transported to the atomizing cannon through the second connecting pipe to provide it with high-pressure water flow to form atomized spray.

[0020] Preferably, the end of the first connecting pipe away from the shell is fixedly connected to a distributed spray topology, and a nozzle is fixedly installed on the upper surface of the distributed spray topology.

[0021] By adopting the above technical solution, the distributed sprinkler topology serves as the end extension structure of the first connecting pipe. The term "distributed" means that it adopts a branch pipeline design, which can divert the water flow delivered by the first connecting pipe to multiple nozzles to achieve uniform coverage of a specific area.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This municipal construction dust suppression spraying device comprises components such as a fixed base, mounting groove, mounting plate, support plate, display screen, temperature and humidity sensor, housing, water collection tank, PLC controller, connecting cables, and relay group. The mounting plate slides within the mounting groove, facilitating quick disassembly, maintenance, or replacement of the support plate. Sensors monitor dust concentration in real time, and the data is transmitted to the PLC controller for comparison with preset thresholds. The relay group then activates the water pump and corresponding area solenoid valves, triggering the spray nozzles to suppress dust. This achieves fully automatic closed-loop control of monitoring and spraying, with a shortened response time. Attached Figure Description

The output end of the pump 19 is fixedly connected to the first connecting pipe 20 and the second connecting pipe 21. The pump 19 is installed on the inner wall of the water collection tank 4 and is the power source of the spray system. Its core function is to draw water stored in the water collection tank 4 and provide sufficient water pressure to ensure that the water flow can be output through the first connecting pipe 20 and the second connecting pipe 21 to form an effective spray.

[0028] Please see Figure 4Solenoid valves 22 are fixedly installed on the outer surfaces of the first connecting pipe 20 and the second connecting pipe 21.

By connecting different positions and different types of nozzles 24, the spraying coverage can be expanded to meet the dust suppression needs of larger construction areas. The spraying mode can also be adjusted according to the dust concentration.

[0029] Please see Figure 1 , Figure 3 , Figure 4 Both the outer surfaces of the shell 3 and the water collection tank 4 are provided with water inlet grooves 11, and the inner walls of the two water inlet grooves 11 are connected.

Construction personnel can directly add water to the water collection tank 4 through the water inlet grooves 11 without opening the sealing structure of the shell 3 or the water collection tank 4, making the operation more convenient. If an automatic water replenishment device is connected, the water inlet grooves 11 can also be used as a fixed interface to ensure the stability of the water replenishment process.

[0030] Please see Figure 1 , Figure 2 , Figure 3 A fixed frame 12 is rotatably connected to the upper surface of the housing 3. A motor 13 is fixedly installed on the outer surface of the fixed frame 12. A connecting rod 14 is fixedly connected to the output end of the motor 13. The fixed frame 12 is rotatably connected to the upper surface of the housing 3 and serves as the bearing base for the motor 13. It can rotate horizontally around the axis of the upper surface of the housing 3, thereby expanding the lateral coverage of the subsequent spraying components. The motor 13 is fixed to the outer surface of the fixed frame 12 and serves as a power source. The connecting rod 14 connected to its output end can drive the connecting rod 14 to rotate.

[0031] Please see Figure 2 , Figure 3 , Figure 4 The fixed frame 12 is equipped with an atomizing cannon 15 inside. The outer surface of the atomizing cannon 15 is fixedly connected to the connecting rod 14. The atomizing cannon 15 is a high-efficiency device for dust control. Its core function is to atomize water into fine particles through high pressure to form a large-area mist water curtain. The water mist combines with dust particles in the air, causing them to settle, thereby quickly reducing the dust concentration. The fixed frame 12 is rotatably connected to the upper surface of the shell 3, driving the atomizing cannon 15 to rotate horizontally.

The distributed design means that it adopts a branch pipeline design, which can divert the water flow delivered by the first connecting pipe 20 to multiple sprinklers 24 to achieve uniform coverage of a specific area.

[0034] The implementation principle of this application embodiment is as follows: First, the mounting plate 6 is horizontally inserted along the mounting groove 5, and then fixed with fixing bolts. The dust concentration in the construction area is monitored in real time by the laser scattering sensor 9, and the temperature and humidity sensor 10 simultaneously collects ambient temperature and humidity data. Then, the sensor transmits the monitoring data to the display screen 8 for real-time display for easy manual observation, and simultaneously sends it to the PLC controller 16 for analysis and processing. The PLC controller 16, as the core control unit, presets a dust concentration threshold and compares the real-time monitoring data with the threshold. If the dust concentration does not exceed the standard, the device remains in standby mode and only continuously monitors. If the dust concentration exceeds the standard, the PLC controller... The device 16 generates control commands based on the degree of exceedance and temperature and humidity data, and sends them to the relay group 18 via the connecting cable 17. After receiving the commands, the relay group 18 controls the corresponding components to start the pump 19 in the water collection tank 4 to draw water from the tank and pressurize it.
