Description

Technical Field

[0001] This invention belongs to the field of civil engineering construction technology, specifically referring to a dust suppression device for civil engineering construction. Background Technology

[0002] Dust pollution is a common environmental problem in the field of building and civil engineering. Long-term exposure to high concentrations of dust not only harms human health but may also cause safety hazards such as equipment wear and tear and reduced visibility.

[0003] To reduce construction dust in the air, dust suppression is generally required. Existing dust suppression technologies mainly include fixed sprinkler systems, high-pressure spray devices, and water truck operations. However, traditional fixed nozzles usually adopt static or simple rotating designs, and their spray angle and water mist diffusion range are relatively fixed, making it difficult to achieve full coverage of irregular areas or dynamic dust points, and easily creating spray dead zones. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a dust suppression device for civil construction, wherein the nozzle can swing in multiple directions to achieve three-dimensional and multi-directional dynamic water mist coverage.

[0005] The technical solution adopted by this invention is as follows: This invention provides a dust suppression device for civil construction, comprising a housing, an adjusting mechanism, and a reciprocating sweeping spray mechanism. The adjusting mechanism is located on the upper wall of the housing, and a water storage component is provided inside the housing. The reciprocating sweeping spray mechanism is mounted on the adjusting mechanism, and a water delivery hose connects the water storage component and the reciprocating sweeping spray mechanism. The reciprocating sweeping spray mechanism includes a fixed cylinder, a reciprocating rotating cylinder, and a sweeping nozzle assembly. The fixed cylinder is rotatably mounted on the adjusting mechanism, and the reciprocating rotating cylinder is... The shaft is rotatably sleeved inside the fixed cylinder. A reciprocating drive is provided between the fixed cylinder and the reciprocating rotating cylinder. A wavy groove is provided on the inner side wall of the fixed cylinder along the circumference. Pushing sliding shafts are distributed at equal intervals along the circumference on the outer wall of the reciprocating rotating cylinder. The pushing sliding shafts are slidably engaged in the wavy groove. A sliding electric actuator is provided inside the fixed cylinder. The end of the sliding electric actuator is rotatably connected to an annular fixing frame. The annular fixing frame is coaxially installed inside the reciprocating rotating cylinder and slidably connected to the reciprocating rotating cylinder. The oscillating sweeping nozzle assembly is located at the end of the annular fixing frame.

[0006] More specifically, the oscillating nozzle assembly includes multiple sets of spaced-apart bends and oscillating nozzles. The bends are located at the end of the annular fixed frame, and the bends and oscillating nozzles are arranged in a circumferential array around the axis of the annular fixed frame. The bends are arranged in a V-shape, and the oscillating nozzles are rotatably positioned between two adjacent sets of bends. The multiple sets of bends and multiple sets of oscillating nozzles are spliced ​​together to form a regular polygonal pipeline. The oscillating nozzles are provided with driven gears, and the front end of the reciprocating rotary drum is provided with racks arranged in a circumferential array around the axis. The racks mesh with the driven gears, and the racks and driven gears correspond one-to-one. The water delivery hose is connected to the lowermost bend.

[0007] More specifically, the annular fixed frame includes a sliding ring, a support column, and a support sleeve. The sliding ring is slidably disposed coaxially within the reciprocating rotary drum. The support columns are arranged in a circumferential array on the side of the sliding ring away from the sliding electric actuator. The support sleeve is disposed at the end of the support column and is V-shaped to fit the curved tube. The curved tube is disposed within the support sleeve. Limiting rings are equidistantly distributed along the circumferential direction on the inner wall of the reciprocating rotary drum. The support column slides through the limiting rings. Through the limiting rings and the support column, the reciprocating rotary drum and the annular fixed frame can slide relative to each other. At the same time, when the reciprocating rotary drum rotates, it can drive the annular fixed frame to rotate synchronously back and forth. The annular fixed frame drives the sweeping nozzle assembly to rotate synchronously back and forth around the axis of the reciprocating rotary drum.

[0008] Preferably, the oscillating nozzle includes a three-way pipe and a nozzle body. The two ends of the three-way pipe on the same axis are rotatably connected between two adjacent bends. The nozzle body is connected to the other end of the three-way pipe. The three-way pipe and the bends are interference-fitted, so that the oscillating nozzle and the bends will not rotate relative to each other without external force.

[0009] The reciprocating drive includes a gear ring, two meshing gear columns, and a stepper motor. The fixed cylinder has an annular groove inside, and a gear cavity communicating with the annular groove is provided on the outside of the fixed cylinder. The gear column is rotatably disposed in the gear cavity. The gear ring is coaxially fixedly disposed on the outside of the reciprocating cylinder and meshes with one of the gear columns. The stepper motor is disposed on the outside of the gear cavity, and the output end of the stepper motor is coaxially fixedly disposed with one of the gear columns.

[0010] As a further improvement to this solution, a nozzle cleaning assembly is provided inside the reciprocating drum. An annular water pipe is provided circumferentially on the outer wall of the reciprocating drum. A branch pipe connects the annular water pipe and the nozzle cleaning assembly, penetrating the side wall of the reciprocating drum. The nozzle cleaning assembly includes a support, a cleaning sleeve, an impeller, a rotating plate, and a flexible brush. The support is located on the inner wall of the reciprocating drum, and the cleaning sleeve is mounted on the support. The side of the cleaning sleeve closest to the oscillating nozzle assembly is open. The rotating plate is rotatably mounted inside the cleaning sleeve. The impeller is coaxially fixed to the rotating plate and the closed end of the cleaning sleeve. The rotating plate has spray holes evenly distributed on its surface. The flexible brush is located on the side of the rotating plate away from the impeller. The branch pipe passes through the closed end of the cleaning sleeve and communicates with the cleaning sleeve. The bottom wall of the cleaning sleeve is connected to a drain pipe. The outer side of the reciprocating rotating cylinder is coaxially provided with an annular drain pipe. The drain pipe passes through the side wall of the reciprocating rotating cylinder and communicates with the annular drain pipe. The upper wall of the casing is provided with a sewage tank. A drain hose is connected between the annular drain pipe and the sewage tank.

[0011] Preferably, the upper wall of the chassis is provided with a cleaning liquid storage tank, the cleaning liquid storage tank is provided with a cleaning pump, the input end of the cleaning pump is connected to the cleaning liquid storage tank, and the output end of the cleaning pump is connected to a ring water pipe with a cleaning hose.

[0012] Preferably, the water storage component includes a water tank, a water pump is installed inside the casing, a water pump is connected to the water tank via a water pump pipe, a water inlet is provided on the water tank, a filter is connected to the water inlet, and a water inlet pipe is provided at the upper end of the filter, which filters the water flow sent into the water tank.

[0013] Preferably, the end of the fixed cylinder away from the nozzle is fixedly connected to a wind duct, the wind duct is equipped with a fan, and the end of the wind duct away from the fixed cylinder is equipped with a filter screen.

[0014] Furthermore, the adjustment mechanism includes a second stepper motor, a mounting bracket, and an electric push rod. A rotating base is rotatably mounted on the upper wall of the housing. The mounting bracket is mounted on the rotating base and is U-shaped. The second stepper motor is located inside the housing, and its output end is coaxially and fixedly connected to the rotating base. One end of the electric push rod is hinged to the rotating base, and the other end is hinged to the side wall of the air duct. The second stepper motor drives the mounting bracket and the reciprocating swaying spray mechanism mounted on the mounting bracket to rotate reciprocally. The electric push rod facilitates the adjustment of the tilt angle of the reciprocating swaying spray mechanism.

[0015] As a further improvement to this solution, a controller is provided inside the chassis, and a control panel is provided on the side wall of the chassis. The controller is electrically connected to the control panel, fan, water pump, cleaning pump, stepper motor one, stepper motor two, sliding electric actuator, and electric actuator.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: 1. Driven by a stepper motor, the reciprocating drum rotates in both directions, causing all nozzles to rotate back and forth around the axis. At the same time, the wave-shaped sliding groove cooperates with the sliding shaft to make the reciprocating drum move back and forth along the axis. Then, through the rack, each nozzle swings at a small angle, forming a composite motion trajectory of rotation and swing. The water mist diffusion range is expanded from the traditional fixed fan shape or circle to a three-dimensional dynamic envelope mist field, which can effectively cover irregular construction areas and dust carried by the wind, and significantly reduce spray blind spots.

[0017] 2. Built-in nozzle cleaning assembly: The nozzle is pushed into the cleaning sleeve by a sliding electric push rod. The cleaning fluid impacts the impeller and drives the flexible brush to rotate and clean the nozzle body. The blockage is cleaned and dust is removed without disassembly. Wastewater is collected in a wastewater tank through a ring drain pipe. The cleaning process is automated and pollution-free, which extends the service life of the nozzle and reduces the amount of manual maintenance.

[0018] 3. Activating the fan can create an auxiliary airflow in front of the nozzle, pushing the water mist to spread further, overcoming the problem that the water mist is easily blown away in windy weather, improving the penetration and coverage radius of the mist droplets, and enhancing the dust suppression capability of the equipment in severe weather.

[0019] 4. In the adjustment mechanism, stepper motor 2 drives the spray mechanism to reciprocate, and electric push rod adjusts the tilt angle of the spray mechanism. Combined with the autonomous movement of the sweeping nozzle assembly, the horizontal angle, vertical height and diffusion range of the water mist coverage can be flexibly adjusted to meet the dust suppression needs of different construction scenarios.

[0020] 5. The filter in the water storage component can filter the water flowing into the water tank, preventing impurities from clogging the nozzles or wearing down the water pump, thereby improving the reliability of the system and the service life of the core components.

At the same time, when the reciprocating drum 7 rotates, it can drive the annular fixed frame 13 to rotate synchronously.

[0033] The oscillating nozzle 15 includes a three-way pipe 22 and a nozzle body 23. The two ends of the three-way pipe 22 on the same axis are rotatably connected between two adjacent bends 14.

Under no external force, the oscillating nozzle 15 and the bends 14 will not rotate relative to each other.

[0034] The reciprocating drum 7 is equipped with a nozzle cleaning assembly 29. An annular water pipe 30 is circumferentially arranged on the outer wall of the reciprocating drum 7. A branch pipe 31 connects the annular water pipe 30 and the nozzle cleaning assembly 29, penetrating the side wall of the reciprocating drum 7. The nozzle cleaning assembly 29 includes a support 32, a cleaning sleeve 33, an impeller 34, a rotating plate 35, and a flexible brush 36. The support 32 is located on the inner wall of the reciprocating drum 7. The cleaning sleeve 33 is mounted on the support 32, with an opening on the side of the cleaning sleeve 33 closest to the oscillating nozzle assembly 8. The rotating plate 35 is rotatably mounted inside the cleaning sleeve 33, and the rotating plate 35 is aligned with the impeller 34. The impeller 34 is located between the closed end of the rotating plate 35 and the cleaning sleeve 33, and the rotating plate 35 is evenly provided with spray holes. The flexible brush 36 is located on the side of the rotating plate 35 away from the impeller 34. The branch pipe 31 passes through the closed end of the cleaning sleeve 33 and communicates with the cleaning sleeve 33. The bottom wall of the cleaning sleeve 33 is connected to a drain pipe 37. The reciprocating drum 7 is coaxially provided with an annular drain pipe 38. The drain pipe 37 passes through the side wall of the reciprocating drum 7 and communicates with the annular drain pipe 38. The upper wall of the casing 1 is provided with a sewage tank 39. A sewage hose 40 is connected between the annular drain pipe 38 and the sewage tank 39.

[0035] The upper wall of the casing 1 is provided with a cleaning liquid storage tank 41, and a cleaning pump 42 is provided on the cleaning liquid storage tank 41. The input end of the cleaning pump 42 is connected to the cleaning liquid storage tank 41, and a cleaning hose 43 is provided between the output end of the cleaning pump 42 and the annular water pipe 30.

[0036] The chassis 1 is equipped with a controller 56, and the side wall of the chassis 1 is equipped with a control panel 57. The controller 56 is electrically connected to the control panel 57, fan 50, water pump 45, cleaning pump 42, stepper motor 26, stepper motor 52, sliding electric actuator 12, and electric actuator 54.

[0037] In practical use, the device is pushed to the location where dust suppression is needed. Then, the electric push rod 54 is extended and retracted via the control panel 57 to adjust the tilt angle of the reciprocating swaying spray mechanism 3. The stepper motor 26, stepper motor 52, and water pump 45 are then activated via the control panel 57. The controller 56 controls stepper motor 52 to periodically rotate in both forward and reverse directions. Stepper motor 52 drives the mounting bracket 53 and the reciprocating swaying spray mechanism 3 mounted on the mounting bracket 53 to rotate reciprocally. The water pump 45 draws water from the water tank 44 through the suction pipe 46, then sends it through the water delivery hose 5 into a regular polygonal pipeline. The water is then distributed through the bend pipe 14 and the tee pipe 22 to the nozzle body 23, where it is atomized and sprayed out. The controller... Stepper motor 26 is controlled to periodically rotate in both forward and reverse directions. Stepper motor 26 drives gear ring 24 to rotate via gear column 25. Gear ring 24 drives reciprocating drum 7 to rotate. When reciprocating drum 7 rotates, it drives annular fixed frame 13 and the oscillating spray nozzle assembly 8 located at the end of annular fixed frame 13 to rotate back and forth around the axis of reciprocating drum 7 via limit ring 21. When reciprocating drum 7 rotates, it drives push sliding shaft 11 to rotate relative to wave-shaped slide groove 10. Wave-shaped slide groove 10 drives reciprocating drum 7 to move back and forth via push sliding shaft 11. Reciprocating drum 7 drives rack 17 to move back and forth relative to driven gear 16. Thus, rack 17 drives driven gear 16 to rotate back and forth slightly. Driven gear 16 drives oscillating nozzle 15 to rotate slightly. The device oscillates back and forth, achieving a three-dimensional, multi-directional, dynamic, and enveloping water mist coverage through the combined motion of multiple sets of oscillating nozzles 15 reciprocating around an axis and the back-and-forth oscillation of each nozzle 15. This reduces dust suppression blind spots. In windy weather, the fan 50 can be activated via the control panel 57 to accelerate water mist diffusion, improve dust suppression range and efficiency, and reduce the impact of strong winds on the water mist. When water needs to be supplied to the water tank 44, the external water pipe is connected to the inlet pipe 48, and the water flows into the water tank 44 after being filtered by the filter 47. When the device stops or the nozzles become clogged or dust accumulates, the stepper motor 1 26, the stepper motor 2 52, and the water pump 45 are shut off via the control panel 57. Then, the sliding electric actuator 12 is controlled to retract, and the sliding electric actuator 12 is fixed by a ring-shaped bracket. 13 drives the oscillating nozzle assembly 8 to move towards the reciprocating drum 7. At this time, the rack 17 is fixed and the driven gear 16 moves relative to the rack 17, thereby the driven gear 16 rotates, driving the oscillating nozzle 15 to rotate towards the reciprocating drum 7. When the driven gear 16 and the rack 17 are not meshed, the axis of the nozzle body 23 is parallel to the axis of the reciprocating drum 7. At this time, the nozzle body 23 is aligned with the cleaning sleeve 33. As the sliding electric actuator 12 continues to retract, the sliding electric actuator 12 drives the nozzle body 23 to extend into the cleaning sleeve 33. Then, the cleaning pump 42 is started through the control panel 57. The cleaning pump 42 delivers the cleaning liquid in the cleaning storage tank 41 to the annular water pipe 30 through the cleaning hose 43, and then enters the cleaning sleeve 33 through the branch pipe 31.The cleaning fluid impacts the impeller 34, causing the rotating plate 35 and flexible brush 36 to rotate, thus performing a rotating scrubbing of the nozzle body 23. The cleaning fluid is sprayed onto the surface of the nozzle body 23 through the spray holes on the rotating plate 35. The wastewater after cleaning flows through the drain pipe 37, the annular drain pipe 38, and the drain hose 40 into the wastewater tank 39 for storage and subsequent unified treatment. After cleaning is completed, the sliding electric push rod 12 is extended and reset, thereby pulling the nozzle body 23 out of the cleaning sleeve 33. When the driven gear 16 meshes with the rack 17 again, the rack 17 drives the driven gear 16 to rotate, thereby causing the oscillating nozzle 15 to rotate and reset.
