Description

Technical Field

[0001] This application relates to the field of construction dust control equipment, and in particular to a dust suppression device for construction projects. Background Technology

[0002] Currently, construction sites generate a large amount of dust, resulting in high levels of dust and other particulate matter in the air near the construction site. This significantly reduces the environmental quality around the construction site. Therefore, in accordance with environmental protection requirements, it is necessary to enclose the construction site and implement dust suppression measures.

[0003] Most existing dust suppression methods are spray dust suppression, which involves fixing a water supply pipe on the fence, with multiple atomizing nozzles fixed at intervals on the water supply pipe. After water is pressurized, it is transported through the water supply pipe to the atomizing nozzles and sprayed out to continuously atomize and suppress dust near the fence, thereby reducing the impact on the environmental quality of the construction site.

[0004] The existing technical solutions mentioned above have the following drawbacks: In this dust suppression method, the range of water sprayed by the atomizing nozzles installed on the water supply pipe is fixed, which results in a fixed and limited dust suppression area that can be covered. Since the water mist sprayed from the nozzles is fan-shaped, there will also be a large blank dust suppression area between two adjacent atomizing nozzles, resulting in a small dust suppression area and poor dust suppression effect. Utility Model Content

[0005] This application provides a dust suppression device for construction projects in order to increase the dust suppression area and thus enhance the dust suppression effect.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A dust suppression device for construction projects includes a mounting box, a swing assembly and a pitch assembly mounted on the mounting box, a dust suppression assembly, and a PLC processor mounted on the mounting box.

[0008] The swing assembly includes a motor disposed inside the mounting box and electrically connected to the PLC processor, and a linkage shaft whose lower end is coaxially connected to the rotation shaft of the motor. The linkage shaft passes through the mounting box and its end away from the motor is located outside the mounting box.

[0009] The pitch assembly includes a lifting component slidably disposed outside the mounting box and sleeved outside the linkage shaft, a linkage component disposed on the upper end of the linkage shaft and slidably connected to the lifting component, a drive component disposed outside the mounting box and used to control the lifting of the lifting component, and an electric push rod disposed inside the mounting box with its piston rod extending to the outside of the mounting box and hinged to one end of the drive component. The end of the drive component away from the electric push rod is slidably connected to the lifting component, and the electric push rod is electrically connected to the PLC processor.

[0010] The dust suppression assembly includes a water supply pipe, a branch pipe with one end fixed to and connected to the wall of the water supply pipe, and a nozzle installed at the other end of the branch pipe. The nozzle is mounted on the linkage component.

[0011] By adopting the above technical solution, the mounting box provides a reliable and stable installation foundation for the entire dust suppression device. After being pressurized by an external water source, the water is sprayed from the nozzles through the supply pipe and branch pipes. The reciprocating rotation of the swing assembly drives the nozzles to swing in the water direction. The electric push rod, through the drive component, causes the lifting component to reciprocate, allowing the pitch component to continuously and stably adjust the pitch angle of the nozzles. This enables the nozzles to swing and adjust their pitch angle synchronously. Compared to fixed nozzles, swinging nozzles significantly increase the effective range of dust suppression. The dust suppression area covered by one swinging nozzle is equivalent to that of three fixed nozzles, reducing the number of nozzles and saving more water resources.

[0012] Optionally, the lifting component includes a sliding sleeve slidably disposed on the mounting box and an annular groove fixedly disposed outside the sliding sleeve and suspended above the upper end of the sliding sleeve. The groove opening of the annular groove faces the center of the annular groove and is slidably connected to the linkage component. A sliding groove is provided on the lower outer end of the sliding sleeve and is slidably connected to the end of the driving component away from the electric push rod.

[0013] By adopting the above technical solution, the lifting component is stably connected to the linkage component and the driving component through the ring groove and sliding groove, which can not only drive the nozzle to operate continuously, but also improve the reliability of the nozzle rotation process.

[0014] Optionally, two annular plates are fixedly connected at intervals to the lower outer side of the sliding sleeve, and the two annular plates and the outer wall of the sliding sleeve form the sliding groove.

[0015] By adopting the above technical solution, the annular groove formed by the two annular plates eliminates the need for adjustment of the lifting and driving components during installation, ensuring that they can always form a reliable connection.

[0016] Optionally, the linkage includes a fixed ball slidably disposed in the annular groove, a connecting rod fixedly connected at one end to the fixed ball, a rotating shaft fixedly connected at the other end of the connecting rod, and a mounting plate mounted on the rotating shaft and spaced apart from the rotating shaft, rotatably disposed on the upper end of the linkage shaft, and the mounting plate being located outside the annular groove.

[0017] By adopting the above technical solution, the fixed ball is set in the annular groove so that the annular groove and the linkage form a stable connection relationship. As the annular groove rises and falls, the fixed ball slides relative to the annular groove. Through the synchronous rotation of the rotating shaft and the mounting plate, the pitch of the nozzle is adjusted.

[0018] Optionally, the connecting rod is L-shaped.

[0019] By adopting the above technical solution, the L-shaped rod structure can avoid the possibility of the fixed ball and the ring groove getting stuck due to strong mechanical stress during the relative sliding process of the fixed ball, connecting rod and ring groove. At the same time, it can also enhance the toughness of the connecting rod, which is conducive to the stable connection and operation of the lifting parts and linkage parts.

[0020] Optionally, the linkage further includes a connecting plate fixed at one end to the rotating shaft and an extension rod fixed at one end to the connecting plate and facing away from the rotating shaft. The connecting plate is L-shaped and its other end is spaced apart from the rotating shaft. A mounting plate is fixed to the other end of the extension rod.

[0021] By adopting the above technical solutions, the connecting plate can change the force on the rotating shaft and improve the rotational stability of the shaft. The extension rod can effectively increase the height of the mounting plate, thereby increasing the pitch angle range of the nozzle.

[0022] Optionally, the driving component includes a driving frame suspended and connected to the outside of the mounting box and a sliding column fixed to one end of the driving frame. One end of the driving frame is machined to form two first driving arms. The two sliding columns are respectively fixed to the two first driving arms and slidably disposed in the sliding groove. The piston rod of the electric push rod is connected to the end of the driving frame away from the first driving arms.

[0023] By adopting the above technical solution, the drive board has a simple structure, which can not only achieve a reliable connection with the lifting components, but also facilitate their lifting.

[0024] Optionally, the distance from the sliding column to the hinge point between the drive frame and the mounting box is less than the distance from the electric push rod piston rod to the hinge point between the drive frame and the mounting box.

[0025] By adopting the above technical solution, the lever arm in the process of driving the lifting component by the drive plate is increased, thereby reducing the load on the electric push rod, reducing the possibility of damage to the electric push rod after long-term operation, and helping to extend the service life of the electric push rod.

[0026] Optionally, the mounting box includes two first side plates that are arranged opposite to each other and connected in sequence, and two second side plates that are detachably connected to the first side plates. Both the first side plates and the second side plates are provided with downward-sloping heat dissipation holes.

[0027] By adopting the above technical solution, the second side plate facilitates the installation of the motor and electric actuator, and the heat dissipation holes can maintain air circulation inside the mounting box, which is beneficial for the long-term use of the motor and electric actuator.

[0028] Optionally, a spring clip is fixed to the outer wall of the first side plate. The spring clip is S-shaped, and the water supply pipe can be locked between the spring clip and the first side plate.

[0029] By adopting the above technical solution, it is easier to attach the water supply pipe to the installation box.

[0030] In summary, this application has the following technical effects:

[0031] 1. By setting up an installation box, a swing component and a pitch component on the installation box, and a dust suppression component, the swing component can drive the nozzle to swing in the water direction after reciprocating rotation. The electric push rod drives the lifting component to reciprocate up and down through the drive component, so that the pitch component can continuously and stably adjust the pitch angle of the nozzle, thereby enabling the nozzle to swing and adjust the pitch angle synchronously. The swing nozzle significantly increases the effective range of dust suppression spray. The dust suppression range covered by one swing nozzle is equivalent to the range of three fixed nozzles, which can reduce the number of nozzles and save more water resources.

[0032] 2. By setting a sliding sleeve and annular groove, the lifting component forms a stable connection with the linkage and driving component, which can not only drive the nozzle to operate continuously, but also improve the reliability of the nozzle rotation process.

[0033] 3. By setting up annular plates, the annular groove formed by two annular plates eliminates the need for adjustment of the lifting and driving components during installation, ensuring that they can always form a reliable connection. Attached Figure Description

Detailed Implementation

[0039] The present application will be further described in detail below with reference to the accompanying drawings.

[0040] This application discloses a dust suppression device for construction projects, combined with... Figure 1 and Figure 2 The dust suppression device includes a mounting box 1, a swing assembly 2 mounted on the mounting box 1, a pitch assembly 3 mounted on the mounting box 1 and slidably connected to the swing assembly 2, and a dust suppression assembly 4 mounted on the mounting box 1.

[0041] Reference Figure 2 The mounting box 1 includes a rectangular, horizontally arranged base plate 11, two rectangular first side plates 12 vertically fixed to opposite sides of the base plate 11, and a rectangular, horizontally fixed top plate 13. The base plate 11, the first side plates 12, and the top plate 13 form two openings, and second side plates 14 are detachably connected to the two openings by screws. The second side plates 14 can completely cover the openings. Several heat dissipation holes 15 are provided on both the first side plates 12 and the second side plates 14. The heat dissipation holes 15 connect the two surfaces of the side plates and are inclined outwards from one end inside the mounting box 1.

[0042] Two fixing plates 16 are vertically fixed to opposite sides of the bottom surface of the base plate 11. Bolts 17 are threaded onto the fixing plates 16. The length direction of the bolts 17 is perpendicular to the plate surface of the fixing plates 16. A circular clamping plate 18 is fixed to the end of the bolt 17 away from the large end. The length direction of the bolt 17 is also perpendicular to the plate surface of the clamping plate 18. Anti-slip pads can be glued to the opposite plates of the two clamping plates 18. Both clamping plates 18 are located between the two fixing plates 16. After the edge of the enclosure is inserted between the two clamping plates 18, rotating the bolts 17 can stably attach the dust suppression device to the enclosure.

[0043] Combination Figure 2 and Figure 3 The swing assembly 2 includes a motor 21 fixedly mounted on the base plate 11 and located within the mounting box 1, and a linkage shaft 22 whose axis is perpendicular to the surface of the top plate 13 and whose lower end is coaxially fixed to the rotating shaft of the motor 21. The linkage shaft 22 rotatably passes through the top plate 13, with its upper end positioned above the top plate 13. In this embodiment, the motor 21 is a stepper motor 21. The mounting box 1 is equipped with a PLC processor (not shown in the figure) electrically connected to the motor 21 and used to control the motor 21. Both the motor 21 and the PLC processor are connected to an external power supply for their operation. The PLC processor controls the motor 21 to reciprocate at a set angle.

[0044] Reference Figure 3 The pitch assembly 3 includes a first fixed cylinder 31 whose lower end is fixed to the outer surface of the top plate 13 and sleeved outside the linkage shaft 22; a lifting member 32 that is slidably sleeved on the outer wall of the first fixed cylinder 31 and can rise and fall along the length of the first fixed cylinder 31; a linkage member 33 that is disposed on the upper end of the linkage shaft 22 and slidably connected to the lifting member 32; a driving member 34 that is disposed on the outer surface of the top plate 13 and slidably connected to the lifting member 32 at one end; and an electric push rod 35 disposed on the inner surface of the bottom plate 11 and located in the mounting box 1. The piston rod of the electric push rod 35 passes through the top plate 13 and is hinged to the end of the driving member 34 away from the lifting member 32. The interior of the first fixed cylinder 31 is cylindrical, and its outer wall is rectangular and machined to form four outer walls. The upper end of the linkage shaft 22 is located above the upper end of the first fixed cylinder 31 and is spaced apart. The electric push rod 35 is electrically connected to the PLC processor and is also connected to an external power supply, so that the PLC processor controls the electric push rod 35 to achieve regular rising and falling.

[0045] Reference Figure 3The lifting component 32 includes a sliding sleeve 321 slidably sleeved on the outer wall of the first fixed cylinder 31, an annular plate 322 sleeved and fixed to the lower section of the outer wall of the sliding sleeve 321, a support rod 323 with its lower end fixed to the upper outer wall of the sliding sleeve 321, and an annular groove 324 horizontally arranged and fixed to the upper end of the support rod 323. The interior of the sliding sleeve 321 is a rectangular hole adapted to the outer wall of the first fixed cylinder 31, and its outer wall is circular. Two annular plates 322 are provided, and the two annular plates 322 are spaced apart and have a sliding groove 325 with its opening facing away from the sliding sleeve 321. The support rod 323 is L-shaped, and its upper end is located above and outside the upper end of the sliding sleeve 321. The annular groove 324 is circular in shape, and its opening faces the center.

[0046] Reference Figure 3 The linkage 33 includes a second fixed cylinder 331 horizontally arranged and fixed to the upper end of the linkage shaft 22, a rotating shaft 332 rotatably arranged inside the second fixed cylinder 331 and with both ends located outside the second fixed cylinder 331, a third fixed cylinder 333 sleeved and fixed to one end of the rotating shaft 332, a connecting rod 334 fixed to the outer wall of the third fixed cylinder 333 at one end, a fixed ball 335 fixed to the end of the connecting rod 334 away from the third fixed cylinder 333 and slidably arranged in the annular groove 324, a connecting plate 336 fixed to the end face of the rotating shaft 332 away from the third fixed cylinder 333, an extension rod 337 fixed to the lower end of the connecting plate 336, and a mounting plate 338 fixed to the upper end of the extension rod 337 and located above the annular groove 324. In this embodiment, the connecting rod 334 is L-shaped, the connecting plate 336 is an L-shaped plate, one plate surface of the connecting plate 336 is fixedly connected to the end face of the rotating shaft 332, and the other plate surface is spaced apart outside the second fixed cylinder 331. The extension rod 337 is set on the plate surface of the connecting plate 336 away from the second fixed cylinder 331.

[0047] Combination Figure 3 and Figure 4 The driving component 34 includes a vertically arranged fixed column 341 with its lower end fixed to the upper surface of the top plate 13, a horizontally arranged driving frame 342 with its lower surface hinged to the upper end of the fixed column 341, a sliding column 343 and a second fixed shaft 344 respectively fixed to both ends of the driving frame 342, and a driving sleeve 345 sleeved on the second fixed shaft 344. The upper end of the electric push rod 35 is fixed to the outer wall of the driving sleeve 345.

[0048] The drive frame 342 is H-shaped, with two opposing first drive arms 3421 at one end and two opposing second drive arms 3422 at the other end. Two sliding columns 343 are horizontally arranged, with one end of each column fixed to the inner wall of the opposing first drive arms 3421. The two sliding columns 343 are slidably arranged in sliding grooves 325 and are always located within the sliding grooves 325. Two fixed seats 3423 are fixedly fixed at intervals on the lower plate of the drive frame 342. A first fixed shaft 3424 with a horizontal axis is fixed between the two fixed seats 3423. The upper end face of the fixed column 341 is machined into a semi-circular surface, and the fixed column 341 is sleeved on the first fixed shaft 3424, thereby forming a hinge between the drive frame 342 and the upper end of the fixed column 341. The distance between the sliding column 343 and the first fixed shaft 3424 is smaller than the distance between the second fixed shaft 344 and the first fixed shaft 3424, so that the section of the drive frame 342 close to the electric push rod 35 can form a longer lever arm, which is beneficial for the electric push rod 35 to lift the lifting component 32.

[0049] Reference Figure 1 The dust suppression component 4 includes a water supply pipe 41 connected to a water source, a branch pipe 42 fixed at one end and connected to the wall of the water supply pipe 41, and a nozzle 43 installed on the end of the branch pipe 42 away from the water supply pipe 41. The nozzle 43 is fixedly mounted on the mounting plate 338. A spring clip 19 is fixedly mounted on the outer surface of a first side plate 12 of the mounting box 1. The side of the spring clip 19 is S-shaped, and the water supply pipe 41 can be locked between the spring clip 19 and the first side plate 12. The branch pipe 42 is made of a high-pressure hose, which can not only transport pressurized water, but also facilitate the swinging of the nozzle 43 on the mounting plate 338.

[0050] The installation box 1 provides a reliable and stable installation base for the dust suppression device. By tightening the bolts 17, the dust suppression device can be stably installed on the enclosure. After being pressurized by an external water source, the water is sprayed out from the nozzle 43 through the water supply pipe 41 and the branch pipe 42. After the power supply to motor 21 and electric push rod 35 is turned on, the PLC processor controls them to work regularly. The electric shaft of motor 21 rotates back and forth, which drives the nozzle 43 to swing in the water direction. The piston rod of electric push rod 35 rises and falls, which drives the lifting component 32 to rise and fall on the first fixed cylinder 31 through the drive component 34. During the rising and falling of the lifting component 32, the annular groove 324, through the fixed ball 335, enables the pitch component 3 to continuously and stably adjust the pitch angle of the nozzle 43, so that the nozzle 43 can swing and adjust the pitch angle synchronously. Compared with the fixed nozzle 43, the swinging nozzle 43 significantly increases the effective range of dust suppression spray. The dust suppression range covered by one swinging nozzle 43 is equivalent to the range of three fixed nozzles 43, which can reduce the number of nozzles 43 and save more water resources.

[0051] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
