Description

Technical Field

[0001] The present application relates to the technical field of dust reduction in construction, and specifically to a high-efficiency dust reduction device for construction. Background Art

[0002] With the continuous implementation of new environmental protection policies, dust control at construction sites has become increasingly normalized. In order to adapt to and meet the requirements of dust control, sprinkler water supply mains are arranged on the external scaffolding, construction site fences (walls), construction roads, earth storage areas and other parts of the construction site, and branch pipes and sprinkler heads are set at intervals. Through the early warning linkage of online dust detection equipment, the sprinkler booster device is immediately started to inject water into the sprinkler pipe. Through the branch pipes and sprinkler heads, the water is evenly sprayed within a certain range to moisten the surface soil and control dust suspended particles, so that the soil is moist and dust-free. The suspended dust gathers and increases weight when it meets water and falls, achieving the effect of suppressing dust.

[0003] However, when the existing spray dust suppression device is working, the sprayed water mist is very likely to be dislocated due to the influence of wind force and cannot contact the suspended particles to the maximum extent, so that the dust suppression effect is reduced and resources are wasted.

[0004] Therefore, it is necessary to provide a kind of high-efficiency dust reduction equipment for building construction to solve the above problems.

[0028] Reference Fig.10 The spray assembly 33 includes a sub-control valve 331, a straight pipe 332, and a spray pipe 333; the sub-control valve 331 is located in the transfer chamber 311, and the outer side is fixedly connected to the transfer chamber 31; one end of the straight pipe 332 is fixedly connected to the output end of the transfer chamber 311, and a rotating joint is provided at the central part of the spray pipe 333, and the input end of the rotating joint is rotatably connected to the straight pipe 332; the spray pipe 333 is a Z-shaped pipe, and nozzles are provided at both ends of the spray pipe 333; therefore, after the water flow enters the spray pipe 333, the spray pipe 333 rotates due to the reaction force of the water pressure, and then the spraying area is circular; A through hole 1 3311 and a through hole 2 3312 are provided on the side of the sub-control valve 331, and the through hole 1 3311 and the through hole 2 3312 are not on the same side; an inner passage 3313, an operating chamber 3314 and an outer passage 3315 are provided inside the sub-control valve 331, and the inner passage 3313, the operating chamber 3314 and the outer passage 3315 are concentrically arranged; the inner passage 3313 is located between the operating chamber 3314 and the outer passage 3315; the inner passage 3313 is columnar, and one end of the inner passage 3313 is connected to the outer passage 3315, and the other end of the inner passage 3313 is connected to the operating chamber 3314, and the outer passage 3315 is located at the bottom of the sub-control valve 331 and is connected to the straight-through pipe 332; one side of the through hole 1 3311 is connected to the outer passage 3315 through a pipeline, and one end of the through hole 2 3312 is connected to the inner passage 3313; A valve 3317 is fixedly installed inside the outer passage 3315, and a valve plug 3318 is movably provided inside the operating chamber 3314, one end of the valve plug 3318 slides through the inner passage 3313 and is embedded in the valve 3317; an electric-controlled telescopic rod 3319 is fixedly installed at one end of the operating chamber 3314 away from the through hole 1 3311, and the movable part of the electric-controlled telescopic rod 3319 is located in the operating chamber 3314 and is fixedly connected to the valve plug 3318; the input end of the electric-controlled telescopic rod 3319 is connected to the signal transmitter electrical signal; therefore, when the speed of the regulating component 32 is accelerated, the electric-controlled telescopic rod 3319 pulls the valve plug 3318 upward, so that the valve plug 3318 is separated from the valve 3317, and the inner passage 3313 and the outer passage 3315 are connected, thereby increasing the water flow rate entering the straight pipe 332, accelerating the water flow rate, and thereby lengthening the lateral distance of the spraying parabola of the spraying pipe 333.

[0029] Embodiment 1: The specific structure of the detection component 46 in the above solution is as follows: Reference Fig.11The detection component 46 includes a truncated cone 461, the top of which is fixedly connected to the rotating support rod 44; an elliptical cavity 4611 is provided on one side of the truncated cone 461, and the end of the elliptical cavity 4611 close to the center of the truncated cone 461 is lower than the end away from the center of the truncated cone 461; a conductive ball 4612 is slidably installed inside the elliptical cavity 4611; a conductive sheet 1 4613 is provided on the end of the elliptical cavity 4611 close to the center of the truncated cone 461, and a conductive sheet 2 4614 is provided on the side close to the bottom of the elliptical cavity 4611, and the conductive sheet 1 4613 and the conductive sheet 2 4614 are connected in series through the conductive ball 4612, and the other ends of the conductive sheet 1 4613 and the conductive sheet 2 4614 are connected to the circuit of the electronic control unit. ; Thus, when the rotating support rod 44 rotates, the truncated table 461 is driven to rotate, and due to the centrifugal force, it moves to the outer edge of the elliptical cavity 4611, so that the circuit where the conductive sheet 1 4613 and the conductive sheet 2 4614 are located is disconnected. At this time, the circuit where the induction body 45 and the electronic control unit are located is in a conducting state. When the induction body 45 moves to the corresponding area of ​​the induction disk 42, it provides power to the corresponding signal transmitter; when the rotating support rod 44 stops rotating, it moves to one end of the elliptical cavity 4611 close to the center of the truncated table 461, so that the circuit where the conductive sheet 1 4613 and the conductive sheet 2 4614 are located is connected. At this time, the circuit where the induction body 45 and the electronic control unit are located is in a short-circuit state, thereby causing the signal transmitter to stop working.

[0030] In summary, during dust suppression operation: water flows from the branch pipe 1 through the cross articulated pipe joint 2 to the spraying mechanisms 3 in four directions; thereby replacing the existing single spraying head for dust suppression, expanding the spraying range of a spraying point, and indirectly improving the dust suppression effect; When the wind blows during spraying: the wind vane body 43 drives the rotating bracket 41 to rotate, and the hemispherical shell 442 drives the rotating support rod to rotate; the wind vane body 43 detects the wind direction, and the corresponding sensing body points to the linkage area 421 close to the wind head, and then the signal transmitter at the corresponding linkage bar 422 sends a command, so that the control component 32 located at the wind head adjusts the angle of the propeller 325, so that the area in contact with the crosswind is increased, and the air resistance generated is increased, so that the rotation speed of the rotor assembly is accelerated; thus, the lift at the spraying mechanism 3 located at the wind head is greater than that at the spraying mechanism 3 located at the wind tail, and then the height of the spraying mechanism 3 located at the wind head is greater than that of the spraying mechanism 3 located at the wind tail, so that the spraying range between multiple spraying mechanisms 3 is as close to the center line as possible, thereby reducing the dislocation effect caused by wind force and reducing the chance of resource waste.

[0031] Embodiment 2: Alternative solution for the structure of the detection component 46 in Embodiment 1: The detection component 46 includes a speed sensor, which is laterally fixed at the bottom of the rotating support rod 44. An iron sheet is installed on the side wall of the placement cavity 411, and the iron sheet and the speed sensor are located on the same cross-section; a control unit is arranged on the top of the branch pipe 1, and the speed sensor and the signal transmitter are respectively connected to the control unit line; therefore, the speed sensor adopts a Hall-type speed sensor; when the speed sensor no longer produces current changes, the control unit turns off the permission signal of the signal transmitter.
