[0009] See also Figure 1-Figure 13 The present invention provides a technical solution: a large-scale dust reduction equipment for construction engineering, comprising a fog cannon 1, a plurality of air guide plates 2 are arranged on the inner side of the left end of the fog cannon 1, the upper and lower ends of the air guide plates 2 on the side away from the output end of the fog cannon 1 are rotatably connected to the inner wall of the fog cannon 1, a swing mechanism is arranged on the top of the left end of the air guide plate 2, and the swing mechanism is used to drive the left ends of the plurality of air guide plates 2 to swing back and forth synchronously, a mounting column 3 is fixedly installed on the top of the fog cannon 1, and a power mechanism is arranged on the outer side of the top end of the mounting column 3, and the power mechanism is used to control the amplitude of the swing of the left end of the air guide plate 2 back and forth according to the size of the wind force on the site, and a direction adjustment mechanism is arranged in the middle of the mounting column 3, and the direction adjustment mechanism is used to adjust the swing direction of the left end of the air guide plate 2 according to the wind direction; The swing mechanism includes a rotating shaft 4 rotatably connected to the inner side of the top of the output end of the fog cannon 1, a rotating disk 5 is fixedly installed at the bottom end of the rotating shaft 4, a sliding rod 6 is fixedly installed at the left end of the rotating disk 5, a sliding block 7 is slidably connected to the outer side of the sliding rod 6, a vertical connecting rod 8 is rotatably connected to the bottom end of the sliding block 7, a horizontal connecting rod 9 is rotatably connected to the bottom end of the vertical connecting rod 8, and a plug rod 10 is fixedly installed on the top of the left end of the wind guide plate 2, and the top end of the plug rod 10 passes through the horizontal connecting rod 9 and is rotatably connected thereto; When working, the output end of the fog cannon 1 is placed toward the position where dust reduction is required, and the fog cannon 1 continues to spray dust reduction; when wind blows in the construction site, the direction adjustment mechanism limits the wind guide plate 2 so that the left end of the wind guide plate 2 can only swing in the direction opposite to the wind direction; at the same time, the power mechanism drives the rotating shaft 4 to rotate under the action of wind force, and the rotation of the rotating shaft 4 drives the turntable 5 to rotate, and the rotation of the turntable 5 drives the sliding bar 6 to swing; taking the wind direction forward and the left end of the sliding bar 6 swinging backward as an example, since the sliding bar 7 is limited by the vertical connecting rod 8 and the horizontal connecting rod 9, the sliding bar 7 slides toward the end of the sliding bar 6 while following the sliding bar 6 to swing backward, and the swing of the sliding bar 7 drives the horizontal connecting rod 9 to move backward through the vertical connecting rod 8, and the horizontal connecting rod 9 moves backward and drives the left end of the air guide plate 2 to swing backward through the plug rod 10. At this time, the water mist blown out by the fog cannon 1 is directed toward the left rear. The water mist blown toward the left rear is deflected forward under the action of wind force, so that it can be accurately blown to the position where dust reduction is required. When the wind direction is backward, the same is true as above, which greatly facilitates the use of the fog cannon 1, improves the efficiency of dust reduction, and improves the utilization rate of water resources. By setting a power mechanism, the device can adjust the angle of water mist deviation according to the size of wind force, which increases the applicability of the device. The staff does not need to manually push the fog cannon 1 for adjustment regularly, which saves labor. The problem that the existing large-scale dust reduction equipment for construction engineering does not have the function of self-adjusting the spray angle according to wind direction is solved.

[0010] As a further solution of the present invention, the power mechanism includes a guide roller 11 fixedly installed on the outer side of the top of the mounting column 3, a plurality of guide annular grooves 12 are opened on the outer side of the guide roller 11, a cylindrical frame 13 is rotatably connected to the outer side of the top of the mounting column 3, the cylindrical frame 13 is located on the outer side of the guide roller 11, and the front, rear, left and right sides of the cylindrical frame 13 are rotatably connected to a plurality of Z-shaped rotating rods 14, the end of the Z-shaped rotating rod 14 close to the guide roller 11 is semicircular and passes through the guide annular groove 12 and is slidably connected thereto, and the end of the Z-shaped rotating rod 14 away from the guide roller 11 is fixedly installed Wind shield 15, several wind shields 15 at the right end are in a vertical state, several wind shields 15 at the left end are in a horizontal state, and several wind shields 15 at the front and rear ends are in an inclined state; a water tank 16 is fixedly installed on the top of the left end of the fog cannon 1, and a water pump 17 is fixedly installed on the top of the water tank 16. A one-way transmission mechanism is provided on the top of the water pump 17. The one-way transmission mechanism is used to drive the blades in the water pump 17 to rotate unidirectionally through the rotation of the cylindrical frame 13. The output end of the water pump 17 is provided with a push-pull mechanism, and the push-pull mechanism is used to control the rotation angle of the rotating shaft 4 according to the flow rate at the output end of the water pump 17; During operation, taking the wind direction forward as an example, a plurality of vertical windshields 15 on the right side move forward under the action of the wind force, and at the same time, the end of the Z-shaped rotating rod 14 is guided by the guide annular groove 12 to rotate inside the cylindrical frame 13, and the rotation of the Z-shaped rotating rod 14 drives the vertical windshield 15 to gradually tilt. When the vertical windshield 15 moves to the left end of the guide roller 11, it rotates into a horizontal state. Similarly, the horizontal guide plate on the left end is rotated between the cylindrical frame 13 and the guide annular groove 12. 2, it gradually moves to the right end of the guide roller 11 and rotates to a vertical state, and the cylindrical frame 13 is driven to rotate continuously in a reciprocating manner. The rotation of the cylindrical frame 13 drives the blades in the water pump 17 to rotate unidirectionally through the one-way transmission mechanism. At this time, the water in the water tank 16 is pumped into the water pump 17 and sprayed out from the right end of the water pump 17. After the water is sprayed out from the right end of the water pump 17, the push-pull mechanism drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 drives the left end of the sliding rod 6 to swing backward, thereby providing power for the swing of the windshield 15.

[0011] As a further solution of the present invention, the one-way transmission mechanism includes a driving shaft 18 fixedly connected to the top of the water pump 17 and the axis of the blades in the water pump 17, the top of the driving shaft 18 is rotatably connected to a first transmission ring 19 through a one-way bearing, the bottom end of the cylindrical frame 13 is fixedly installed with a second transmission ring 20, the top of the front end of the water pump 17 is rotatably connected to a switching shaft 21, the top of the switching shaft 21 is rotatably connected to a third transmission ring 22 through a one-way bearing, the first transmission ring 19, the second transmission ring 20 and the third transmission ring 22 are connected by a transmission belt 23, and the outer sides of the driving shaft 18 and the switching shaft 21 are fixedly installed with switching gears 24, and the two switching gears 24 are meshed with each other; During operation, taking the clockwise rotation of the cylindrical frame 13 observed from top to bottom as an example, the clockwise rotation of the cylindrical frame 13 drives the second transmission ring 20 to rotate clockwise, and the clockwise rotation of the second transmission ring 20 drives the first transmission ring 19 and the third transmission ring 22 to rotate clockwise through the transmission belt 23. At this time, the rotation of the first transmission ring 19 drives the drive shaft 18 and the blades of the water pump 17 to rotate clockwise through the one-way bearing, thereby sucking the water in the water tank 16 into the water pump 17 and spraying it from the right output end of the water pump 17. The rotation of the third transmission ring 22 cannot drive the switching shaft 21 to rotate under the action of the one-way bearing. At the same time, the rotation of the drive shaft 18 drives the switching shaft 21 to rotate in the opposite direction through the two switching gears 24. At this time, the rotation of the switching shaft 21 will not cause the third transmission ring 22 to rotate under the action of the one-way bearing. The counterclockwise rotation of the cylindrical frame 13 drives the second transmission ring 20 to rotate counterclockwise, and the counterclockwise rotation of the second transmission ring 20 drives the first transmission ring 19 and the third transmission ring 22 to rotate counterclockwise through the transmission belt 23. The counterclockwise rotation of the first transmission ring 19 cannot drive the drive shaft 18 to rotate under the action of the one-way bearing. The counterclockwise rotation of the third transmission ring 22 drives the switching shaft 21 to rotate counterclockwise under the action of the one-way bearing. The counterclockwise rotation of the switching shaft 21 drives the drive shaft 18 to rotate clockwise through the two switching gears 24, thereby achieving that no matter how the cylindrical frame 13 rotates under the action of the wind, it will not affect the rotation direction of the drive shaft 18 and the blades in the water pump 17, which brings convenience to the use of the water pump 17.

[0012] As a further solution of the present invention, the push-pull mechanism includes a piston cylinder 25 fixedly installed at the output end of the water pump 17, a drain pipe 26 is fixedly installed at the bottom of the left end of the piston cylinder 25 and connected to the piston cylinder 25, the bottom end of the drain pipe 26 is located inside the water tank 16, a piston block 27 is slidably connected to the inner side of the piston cylinder 25, a telescopic rod 28 is fixedly installed at the right end of the piston block 27, a connecting box 29 is fixedly installed at the right end of the telescopic rod 28, the left end of the connecting box 29 is connected to the piston cylinder 25 through a tension spring, a lifting rod 30 is slidably connected to the right end of the connecting box 29, and a special-shaped plate 31 is fixedly installed at the bottom end of the lifting rod 30; the top end of the rotating shaft 4 passes through the fog cannon machine 1 and is fixedly installed with a worm gear 32, and the top of the left end of the fog cannon machine 1 is rotatably connected with The worm 33 and the worm wheel 32 are meshed with the worm 33, and the front and rear ends of the worm 33 are fixedly installed with a push-pull gear 34. Two slide grooves 35 are provided on the top of the left end of the fog cannon 1. The inner side of the left end of the front slide groove 35 is slidably connected with a push-pull rack 36 through a tension spring. The push-pull rack 36 is located at the lower side of the front push-pull gear 34. The inner side of the left end of the rear slide groove 35 is slidably connected with an N-shaped frame 37 through a tension spring. A plurality of linear array teeth 38 are fixedly installed on the inner side of the top end of the N-shaped frame 37. The teeth 38 are all located on the upper side of the rear push-pull gear 34. The right end of the push-pull rack 36 and the right end of the top end of the N-shaped frame 37 are fixedly installed with a push-pull block 39, and the rear end of the front push-pull block 39 corresponds to the special-shaped plate 31. During operation, water ejected from the right output end of the water pump 17 enters the piston cylinder 25 and pushes the piston block 27 to move rightward. Taking the wind direction facing forward as an example, the piston block 27 moves rightward and drives the lifting rod 30 and the special-shaped plate 31 to move rightward through the telescopic rod 28 and the connecting box 29. The special-shaped plate 31 moves rightward and drives the front push-pull block 39 to move rightward. The front push-pull block 39 moves rightward and drives the push-pull rack 36 to move rightward. The push-pull rack 36 moves rightward and drives the front push-pull gear 34 to rotate counterclockwise. The front push-pull gear 34 rotates counterclockwise and drives the worm 33 to rotate counterclockwise. The worm 33 rotates clockwise and counterclockwise through the worm gear 32 to drive the rotating shaft 4 and the turntable 5 to rotate. The rotation of the turntable 5 drives the end of the slide bar 6 to move backward, thereby driving the left ends of the several wind guide plates 2 to deviate backward. The faster the wind speed in the venue, the faster the water flow rate sprayed from the right output end of the water pump 17. At this time, the more the piston block 27 moves to the right, thereby making the offset angle of the end of the slide bar 6 larger. At the same time, the larger the backward offset of the left end of the wind guide plate 2, thereby realizing the control of the angle of the water mist blown out by the fog cannon 1 according to the size of the wind speed, thereby increasing the practicality of the device.

[0013] As a further solution of the present invention, the direction adjustment mechanism includes a mounting ring 40 rotatably connected to the middle of the mounting column 3, a wing plate 41 is fixedly installed on the right end of the mounting ring 40, an elastic band 42 is fixedly installed on the lower side of the left end of the wing plate 41, and the other end of the elastic band 42 is fixedly connected to the mounting column 3. A lifting mechanism is provided at the left end of the mounting ring 40, and the lifting mechanism is used to drive the lifting rod 30 to move upward when the right end of the wing plate 41 swings backward; When the wind blows, the right end of the wing plate 41 swings backwards, and the wing plate 41 swings backwards. Driven by the lifting mechanism, the lifting rod 30 moves upward, and the lifting rod 30 moves upward to drive the special-shaped plate 31 to move upward. The special-shaped plate 31 moves upward so that the push-pull block 39 at the rear side corresponds to the rear end of the special-shaped plate 31. When the piston block 27 moves to the right, the special-shaped plate 31 moves to the right and pushes the rear push-pull block 39 to move to the right. At this time, the special-shaped plate 31 passes over the top of the front push-pull block 39, and the rear push-pull block 39 moves to the right and drives the rear push-pull gear 34 to rotate clockwise through the teeth 38. The rear push-pull gear 34 rotates clockwise to drive the worm 33 to rotate clockwise. The worm 33 rotates clockwise through the worm gear 32 and the rotating shaft 4 to drive the end of the slide rod 6 to move forward, thereby driving the left end of the plurality of wind guide plates 2 to deviate forward, so that the wind guide plate 2 can be automatically adjusted according to the wind direction, which brings convenience to the use of the equipment.

[0014] As a further solution of the present invention, a shift rod 43 is fixedly installed on the right front side and the right rear side of the middle part of the mounting column 3, and the shift rod 43 corresponds to the wing plate 41; When working, the wing plate 41 will be limited by the shifting rod 43 when it deviates forward or backward to a certain extent, so that the wing plate 41 will not rotate to the left side of the mounting column 3 under the action of wind and be difficult to reset. When the wind direction changes during use, it can be adjusted in time, which brings convenience to the operation of the adjustment mechanism.

[0015] As a further solution of the present invention, the lifting mechanism includes a magnetic plate 44 fixedly mounted on the left rear side of the top end of the mounting ring 40, the magnetic plate 44 is fan-shaped, and a magnet 45 is fixedly mounted on the top end of the lifting rod 30; During operation, the right end of the wing plate 41 swings backward under the blowing, and the left end of the magnetic plate 44 swings forward and moves to just above the magnet 45. At this time, the magnet 45 is attracted by the magnetic plate 44 to drive the lifting rod 30 to move upward, thereby driving the special-shaped plate 31 to move upward, which facilitates the up and down movement of the special-shaped plate 31.
