Description

Technical Field

[0002] According to the patent document with the authorization announcement number "CN220276598U" and the invention name "A dust reduction sprinkler for construction", the description states: the water pipe can rotate with the shaft to adjust the size of the dust reduction area. When the water pipe is in a horizontal state, the dust reduction area is the largest, and when the water pipe is vertically upward, the dust reduction area is the smallest.

Under the action of the driving motor 704, the longitudinal pipe 701 is driven to rotate in a certain regular forward and reverse direction to expand the spray range of the water mist. At the same time, the nozzle 7064 is installed on the rotating disk 7063. When the rack 7071 moves back and forth horizontally, it drives the nozzle 7064 to swing back and forth, expanding the spray angle range of the water mist, increasing the chance of the mist droplets colliding with the dust to capture the dust, and improving the dust reduction effect.

[0033] The swing control unit 707 includes a moving frame 7072 symmetrically mounted on the outside of the transverse tube 702, two racks 7071 are symmetrically mounted on the bottom end of the moving frame 7072, the racks 7071 are meshed with the second gears 7066 on the same side, the moving frame 7072 is arranged in an N shape, the moving frame 7072 is slidably mounted on a guide frame 7073, the guide frame 7073 is fixedly mounted on the top end of the transverse tube 702, and a top box 7074 is fixedly mounted on the top end of the transverse tube 702.

The rod groove 7078 The rod groove 7078 is connected to the horizontal tube 702, and a fixing rod 7079 is installed inside the rod groove 7078. The fixing rod 7079 is coaxially arranged with the longitudinal tube 701. The bottom end of the fixing rod 7079 is fixedly installed on the inner bottom wall of the water tank 2. The diameter of the fixing rod 7079 is smaller than the inner diameter of the longitudinal tube 701. The outer wall of the fixing rod 7079 is in close contact with the inner wall of the rod groove 7078. The top of the fixing rod 7079 is fixedly installed with a screw 70710. The screw 70710 is threadedly connected with the longitudinal movement block 7076. The longitudinal movement block 7076 moves with the fixing rod 7079. As the longitudinal tube 701 rotates, the screw 70710 is fixed to the water tank 2, so that during the forward and reverse rotation of the longitudinal block 7076, under the action of the screw 70710, it moves longitudinally back and forth inside the top box 7074, and then pulls the movable frame 7072 to move laterally back and forth along the guide frame 7073, thereby driving the rack 7071 to move laterally back and forth, driving the nozzle 7064 to swing back and forth continuously, and facilitating the continuous change of the water mist spraying angle, increasing the chance of mist droplets colliding with dust to capture dust, and improving the dust reduction effect.

[0034] The spray speed regulating unit 708 includes a movable groove 7081 provided inside the rotating shaft 7065, one end of the movable groove 7081 is connected to the inner cavity of the rotating disk 7063, an end groove 7082 is provided at the end of the movable groove 7081 away from the bottom box 7061, the diameter of the end groove 7082 is smaller than the diameter of the movable groove 7081, the end groove 7082 penetrates to the side of the second gear 7066 away from the bottom box 7061, and a piston 7083 is movably installed inside the movable groove 7081. The outer wall of 7083 is in close contact with the inner wall of the movable groove 7081. A connecting rod 7084 is installed on the side of the piston 7083 away from the bottom box 7061. The connecting rod 7084 is located inside the end groove 7082. A pressure block 7085 is fixedly installed on one end of the connecting rod 7084. The pressure block 7085 is located on the side of the second gear 7066 away from the bottom box 7061. A spring 7086 is fixedly installed on the side of the piston 7083 away from the bottom box 7061. One end of the spring 7086 is in close contact with the movable groove 7081. The movable groove 7081 is fixedly connected to the inner wall of one end away from the bottom box 7061, and the side of the pressure block 7085 away from the bottom box 7061 is provided with a side plate 7088, and the side of the side plate 7088 close to the bottom box 7061 is equidistantly installed with extrusion blocks 7089, and the top of the side plate 7088 is installed with a connecting plate 7087, and the connecting plate 7087 is fixedly connected to the rack 7071. When the side plate 7088 moves with the rack 7071, the extrusion block 7089 pushes the pressure block 7085. The side plate 7088 reciprocates with the rack 7071. When the extrusion block 7089 passes the pressure block 7085, it pushes the piston 7083 toward the rotating disk 7063. Since the water pressure of the water flow entering the bottom box 7061 is constant, when the piston 7083 moves toward the rotating disk 7063, the pressure on the water flow is increased, which speeds up the spraying speed of the water mist from the nozzle 7064, so that the spraying speed of the water mist changes continuously, thereby facilitating the capture of dust particles of different sizes and improving the dust reduction effect.

[0035] Working principle: When working, first open valve 4 to let water flow into the space below water pressure plate 5 inside water tank 2, close valve 4, and when in use, control the output end of cylinder 6 to move downward, push water pressure plate 5 to move downward, push water from longitudinal pipe 701 into transverse pipe 702, and finally spray out from nozzle 7064 through bottom box 7061 and water inlet trough 7067, so that water mist combines with dust particles in the air to reduce dust;

[0036] At the same time, the driving motor 704 is turned on to control the first gear 705 to rotate in a regular forward and reverse direction. Since the first gear 705 is meshed with the gear ring 703, the transverse tube 702 is driven to rotate, so that the spray range of the water mist is expanded and the dust removal effect is improved. During the forward and reverse rotation of the transverse tube 702, since the screw 70710 is fixedly connected to the water tank 2 through the fixing rod 7079, the longitudinal movement block 7076 and the screw 70710 rotate relative to each other. When the longitudinal movement block 7076 rotates clockwise, it moves upward under the action of the screw 70710. When the longitudinal moving block 7076 rotates counterclockwise, it moves downward under the action of the screw 70710, and then pulls the moving frame 7072 to move back and forth laterally along the guide frame 7073 through the connecting rod 7077, and then drives the rack 7071 to rotate back and forth laterally. Since the rack 7071 is meshed with the second gear 7066, the rack 7071 moves back and forth laterally, driving the second gear 7066 to rotate back and forth in the rotating circular groove 7062, and the nozzle 7064 swings back and forth, expanding the spray angle of the water mist and increasing the chance of the mist droplets colliding with the dust to capture the dust;

[0037] When the water flows into the rotating disk 7063, part of the water flows into the movable groove 7081. At the same time, during the lateral reciprocating movement of the rack 7071, the side plate 7088 is driven to move lateral reciprocatingly. When the extrusion block 7089 moves toward the pressure block 7085, the pressure block 7085 is squeezed to push the piston 7083 toward the rotating disk 7063. Since the water inlet pressure of the bottom box 7061 cannot be changed, when the piston 7083 moves toward the rotating disk 7063, the water pressure is increased, so that the spraying speed of the water mist from the nozzle 7064 is increased, so that when the nozzle 7064 is continuously adjusted in angle, the spraying speed of the water mist is continuously changed, thereby facilitating the capture of dust particles of different sizes and improving the dust reduction effect.
