[0017] The technical solution provided in this disclosure may include the following beneficial effects:

[0018] The equipment is placed on the construction site using a base. Motor 1 drives fan blades 1 and 2 to rotate at high speed inside the air duct via a main shaft. This draws in surrounding air, filtered through a mesh screen, into the inner side of the intake. A water pump delivers water to the inner side of the connecting pipe. Through a sealed sleeve, water enters the inner side of the ring pipe via a conduit, and is then atomized and sprayed onto the inner side of the air duct by multiple nozzles. The high-speed airflow generated by fan blades 1 and 2 blows the water out. This serves two purposes: firstly, the sprayed water mist comes into contact with flying dust, wetting it and causing it to fall; secondly, it directs the airflow towards the rear and sides... Dust is drawn into the inside of the duct through the suction inlet, where it mixes with water mist and falls to the ground after being blown out by the airflow. Motor 2 drives a gear to rotate via a long shaft. The gear meshes with a gear ring, causing a retainer to rotate on top of the support sleeve. Motor 3 drives a worm to rotate. The worm meshes with a worm wheel, causing the worm wheel to rotate up and down. This causes the worm wheel to drive a rotating rod to rotate back and forth on the support plate. The rotating rod, through the support plate, causes the duct to rotate up and down, thus enabling the duct to rotate horizontally and deflect up and down. This allows for comprehensive dust suppression spraying in all directions, increasing the coverage area of ​​dust suppression and improving environmental protection.

[0019] When dust drawn in through the suction inlet mixes with water on the inner side of the fan duct, a small amount of dust and moisture adheres to the outer sides of fan blades one and two, increasing their weight. Simultaneously, the dust and moisture reduce the smoothness of the fan blades, thus decreasing their rotational speed. Furthermore, the increased frictional resistance of fan blades to the airflow reduces the blowing force generated by motor one via the main shaft, resulting in less blowing force on the baffle. This, in turn, causes the baffle to move via a connecting rod, triggering a hinged plate to spring... When the tension of spring one decreases, spring one pushes the flap to the left, the flap presses button one, button one turns on the high-pressure pump, the high-pressure pump draws water from the inside of the conduit through the pipe and delivers the high-pressure water to the inside of the spray gun, and then sprays it out at high pressure towards the outer sides of the bottom of fan blade one and fan blade two respectively. In conjunction with the rotation of fan blade one and fan blade two, it effectively cleans fan blade one and fan blade two, preventing the airflow from decreasing due to a large amount of dust adhering to fan blade one and fan blade two, and ensuring the working range of the equipment's spray dust suppression.

[0020] When large impurities (such as leaves, plastic bags, etc.) adhere to the screen, the airflow speed drawn into the duct through the suction port decreases, which in turn reduces the airflow speed blown outward from the duct. At this time, the baffle, due to the reduced blowing force, moves a hinged plate via a connecting rod to reduce the tension on spring one. Spring one pushes the hinged plate to the left. If the surfaces of fan blades one and two are relatively clean, they maintain high-speed rotation and generate a high suction force on the inside of the duct, causing the air pressure inside the duct to drop. This negative pressure is transmitted through a thin tube to the inside of the left end of the sliding sleeve, attracting the piston. The piston compresses spring two and moves it to the left, preventing the hinged plate from pressing button one, thus eliminating the need for fan blade cleaning. The piston presses button two, triggering an alarm to remind personnel to clean the screen, preventing the high-pressure pump from being accidentally turned on, reducing water and electricity waste, and preventing fan blades one and two from being damaged too quickly due to excessive cleaning, thus ensuring the lifespan of the fan blades.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0034] like Figure 1 , Figure 5 , Figure 8 , Figure 9As shown in the figure, this disclosure proposes an environmentally friendly dust suppression spraying device for construction sites, comprising: a blowing assembly, which includes a blower 7 and a suction port 8; a rotating assembly installed on the inner side of the blower 7, which includes a motor 10 and a main shaft 11; a fan assembly installed on the main shaft 11, which includes a fan blade 12 and a fan blade 13; a support assembly installed at the bottom of the blower 7, which includes a support plate 6 and a rotating rod 5; a connecting assembly installed on the outer side of the rotating rod 5, which includes a support plate 4 and a retaining sleeve 3; and a fixing assembly installed at the bottom of the retaining sleeve 3, which includes a base 1. The system includes a support sleeve 2; a spray assembly comprising a water pump 14 and a connecting pipe 15, a sealing assembly mounted on the connecting pipe 15, the sealing assembly comprising a sealing sleeve 16 and a conduit 17, an atomizing assembly mounted on the conduit 17, the atomizing assembly comprising a ring pipe 18 and a nozzle 19, a cleaning assembly mounted on the conduit 17, the cleaning assembly comprising a high-pressure pump 37 and a spray gun 38; and a control assembly comprising a sliding sleeve 27 and a worm gear 24, a tilting assembly mounted at the bottom of the worm gear 24, the tilting assembly comprising a motor 26 and a worm 25, and a rotating assembly mounted at the bottom of the worm 25, the rotating assembly comprising a gear 2. 2 and motor 20, a sliding assembly is installed on the inner side of the sliding sleeve 27, the sliding assembly includes a flap 30 and a piston 33, a wind-driven assembly is installed on the flap 30, the wind-driven assembly includes a connecting rod 31 and a baffle 29, a spring assembly is installed on the inner side of the sliding sleeve 27, the spring assembly includes a first spring 32 and a second spring 34, a control assembly is installed on the inner side of the sliding sleeve 27, the control assembly includes a first button 35 and a second button 36, the baffle 29 is located on one side of the second fan blade 13, the connecting hole is located on the other side of the first fan blade 12, the outer side of the piston 33 is engaged with the inner wall of the sliding sleeve 27, and the flap 30 is located on the piston 33. On one side of the piston 33, the other side of the piston 33 is connected to the inner wall of the other end of the sliding sleeve 27 via spring 2 34. Button 1 35 is bolted to one side of the piston 33. Button 2 36 is bolted to the inner wall of the top of the sliding sleeve 27. Button 2 36 is located on the other side of the piston 33. An external switch assembly is connected to the air duct 7. An alarm is bolted to the air duct 7. The switch assembly is connected to button 1 35, button 2 36, water pump 14, motor 10, motor 20 and motor 3 26 via wires. Button 1 35 is connected to the high-pressure pump 37 via wires. Button 2 36 is connected to the alarm via wires.

[0035] Understandably, when larger impurities (such as leaves, plastic bags, etc.) adhere to the partition net 9, the airflow speed drawn into the duct 7 through the suction port 8 decreases, which in turn reduces the airflow speed blowing outward from the duct 7. At this time, although the baffle 29 will also experience a decrease in blowing force due to the reduced force, it will reduce the tension on the spring 32 via the connecting rod 31, causing the spring 32 to push the flap 30 to move to the left. If the surfaces of the fan blades 12 and 13 are relatively clean, the fan blades 12 and 13 will maintain high-speed rotation and generate a high suction force on the inside of the duct 7, thus increasing the airflow speed. The air pressure inside cylinder 7 drops, and the negative pressure is transmitted through thin tube 28 to the inner side of the left end of sliding sleeve 27. This negative pressure attracts piston 33, which compresses spring 2 34 and moves it to the left. Consequently, the movement of flap 30 can no longer press button 1 35, eliminating the need for fan blade cleaning. Piston 33 presses button 2 36 and triggers an alarm to remind personnel to clean screen 9, preventing high-pressure pump 37 from being accidentally turned on, reducing water and electricity waste, and preventing fan blades 1 12 and 2 13 from being damaged by excessive cleaning, thus ensuring the service life of the fan blades.

[0036] like Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the bottom of the support sleeve 2 is bolted to the top of the base 1, the bottom of the clamping sleeve 3 is sleeved on the top of the support sleeve 2 via a bearing, the bottom of the support plate 4 is welded to the top of the clamping sleeve 3, and a through cavity is formed on the inner side of the support plate 4.

One end of the rotating rod 5 is installed on one side of the support plate 4, and the other end of the rotating rod 5 passes through the through cavity and extends to the other side of the support plate 4. The bottom of the support plate 6 is welded to both ends of the rotating rod 5, and the top of the support plate 6 is bolted to the bottom of the air duct 7. The suction port 8 is integrally formed on one end of the air duct 7, and a mesh is bolted to the outer side of the suction port 8. 9. The motor 10 is bolted to the inside of the air duct 7. The main shaft 11 is bolted to the output shaft of the motor 10. The fan blade 12 is bolted to one end of the main shaft 11. The fan blade 13 is bolted to the other end of the main shaft 11. The fan blades 12 and 13 are evenly distributed on the outside of the main shaft 11. The fan blade 13 is located on the inside of the other end of the air duct 7. The motor 20 is bolted to the top of the base 1. A long shaft 21 is bolted to the output shaft of the motor 20. Both the motor 20 and the long shaft 21 are located inside the support sleeve 2. A gear ring 23 is welded to the inner wall of the clamp 3. The gear 22 is bolted to the long shaft 21. At the top of shaft 21, gear 22 meshes with gear ring 23. Worm gear 24 is sleeved on the outer side of rotating rod 5 and is bolted to the middle of rotating rod 5. Worm 25 is mounted on the inner side of support plate 4 via rotating shaft. Worm gear 24 and worm 25 are both located inside the through cavity and are connected. Motor 3 26 is bolted to one side of support plate 4. The output shaft of motor 3 26 is keyed to one end of worm 25. Water pump 14 is bolted to the top of base 1. One end of connecting pipe 15 is bolted to the bottom of water pump 14, and the other end of connecting pipe 15 passes through the outer wall of support sleeve 2 and extends to the inner side of support sleeve 2. The other end of 5 is located at the top inside the support sleeve 2. The sealing sleeve 16 is fitted on the outer side of the other end of the connecting pipe 15. One end of the conduit 17 is sealed and installed on the top of the sealing sleeve 16 by bolts. The other end of the conduit 17 passes through the inner wall of the clamp 3 and extends to the bottom of the air duct 7. The ring pipe 18 is fitted on the outer side of the air duct 7.

The nozzle 19 is welded and fixed to the inner side of the air duct 7. The nozzles 19 are evenly distributed on the inner side of the air duct 7.

[0037] Understandably, the equipment is placed on the construction site via base 1. Motor 10 drives fan blades 12 and 13 to rotate at high speed inside the air duct 7 via main shaft 11, drawing in ambient air filtered through mesh 9 and into the suction port 8. Water pump 14 pumps water to the inside of connecting pipe 15. With the connection of sealing sleeve 16, water enters the inside of ring pipe 18 through conduit 17, and is then atomized and sprayed onto the inside of air duct 7 through multiple nozzles 19. The high-speed airflow generated by fan blades 12 and 13 blows the water out. On one hand, the blown water mist comes into contact with the flying dust, wetting it and causing it to fall. On the other hand, it directs the airflow to the rear and sides of the air duct. Dust from the side is drawn into the inside of the air duct 7 through the suction port 8, where it mixes with water mist and falls to the ground after being blown out by the airflow. Motor 20 drives gear 22 to rotate through long shaft 21. Gear 22, through meshing with gear ring 23, drives sleeve 3 to rotate on top of support sleeve 2. Motor 3 drives worm 25 to rotate. Worm 25, through meshing with worm wheel 24, drives worm wheel 24 to rotate up and down. This causes worm wheel 24 to drive rotating rod 5 to rotate back and forth on support plate 4. Rotating rod 5, through support plate 6, drives air duct 7 to rotate up and down. This allows air duct 7 to rotate horizontally and deflect up and down, enabling comprehensive dust suppression spraying around the area, increasing the dust suppression range, and thus improving environmental protection.

[0038] like Figure 3 , Figure 6 , Figure 7 and Figure 9 As shown, the high-pressure pump 37 is bolted to the bottom of the air duct 7. The bottom of the high-pressure pump 37 is connected to the conduit 17 via a pipe. The bottom of the spray gun 38 is bolted to the top of the high-pressure pump 37. The top of the spray gun 38 passes through the bottom of the air duct 7 and extends to the inside of the air duct 7. The top of the spray gun 38 is located at the bottom of fan blade 12 and fan blade 13, respectively. The sliding sleeve 27 is bolted to the top of the air duct 7. The movable plate 30 is installed inside the sliding sleeve 27. One side of the movable plate 30 is connected to the inner wall of one end of the sliding sleeve 27 via a spring 32. One end of the duct 7 has a sliding opening. One end of the connecting rod 31 is anchored to the inside of the flap 30. The other end of the connecting rod 31 passes through the sliding opening and extends to the outside of the sliding sleeve 27. The top of the baffle 29 is welded to the other end of the connecting rod 31. The baffle 29 is located on the outside of the other end of the duct 7. The other end of the sliding sleeve 27 has an air hole. The top of the duct 7 has a connecting hole. A thin tube 28 is installed on the duct 7. The two ends of the thin tube 28 are welded to the duct 7 and the sliding sleeve 27, respectively. The other end of the sliding sleeve 27 is connected to the inside of the duct 7 in sequence through the air hole, the thin tube 28 and the connecting hole.

[0039] Understandably, when the dust drawn in through the suction port 8 mixes with the water level inside the fan duct 7, a small amount of dust and moisture will adhere to the outer sides of fan blades 12 and 13, increasing their weight. Simultaneously, the dust and moisture reduce the smoothness of the fan blades, thus decreasing their rotational speed. Furthermore, the increased frictional resistance of fan blades to the airflow leads to a decrease in the blowing force generated by the motor 10 via the main shaft 11, resulting in reduced blowing force on the baffle 29. This, in turn, causes the baffle 29 to drive the hinge 3 via the connecting rod 31. The tension of spring 32 decreases, and spring 32 pushes the flap 30 to move to the left. The flap 30 presses button 35, which turns on the high-pressure pump 37. The high-pressure pump 37 draws water from the inside of the conduit 17 through the pipe and delivers the high-pressure water to the inside of the spray gun 38. The water is then sprayed at high pressure towards the outer sides of the bottom of fan blade 12 and fan blade 23 respectively. In conjunction with the rotation of fan blade 12 and fan blade 23, the spray gun effectively cleans fan blade 12 and fan blade 23, preventing the airflow from decreasing due to the accumulation of dust on fan blade 12 and fan blade 23, thus ensuring the working range of the equipment's dust suppression spray.
