This invention discloses a spray cooling and dust removal device for building construction, specifically relating to the field of spray dust removal and separation technology. It includes a mobile platform, a water tank, a support frame, a support block, an inclined frame, and a side-mounted synchronous displacement spray dust removal mechanism. The side-mounted synchronous displacement spray dust removal mechanism includes a screw, a displacement motor, and a threaded sleeve, as well as front and rear synchronous displacement spray dust removal mechanisms and a top synchronous displacement spray dust removal assembly.

Description

Technical Field

[0001] This invention relates to the field of spray dust removal and separation technology, and more specifically, to a spray cooling and dust removal device for building construction. Background Technology

[0002] In air pollution control, construction site spray cooling and dust removal devices are needed. They have a cooling effect, which can effectively reduce the surface temperature of the construction site during hot seasons, reducing the risk of heatstroke for workers. Secondly, they have a dust reduction effect, which can quickly reduce the concentration of dust in the air, improve the construction environment, reduce suspended particulate matter in the air, and thus reduce the impact of dust on surrounding residents and the ecological environment.

[0003] A search of existing published literature revealed a Chinese patent (publication number CN111686538A) that discloses a water spraying device for heatstroke prevention and dust suppression in construction sites. This technology uses a pushing mechanism to spray water; a power component, mounted on a water storage tank, provides power through rotation; and a swinging component, mounted on a mounting frame, swings through rotation. This invention can spray water onto construction sites to cool them and reduce dust. However, this technology still has the following problems.

[0004] During construction, spray cooling and dust removal devices are needed to separate dust from the air by spraying water. However, when spraying dust during construction, since each nozzle is in a fixed position and the dust covers a wide area, it is difficult to achieve synchronous spraying on the sides, front, back, and top inclined surfaces. This results in a small contact area between the sprayed water and the air dust, leading to poor dust removal efficiency. Therefore, a spray cooling and dust removal device for construction is provided. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a spray cooling and dust removal device for building construction, comprising a mobile platform, a water tank and a support frame, wherein the water tank is located above the mobile platform, the support frame is located on one side of the water tank, the support frame is fixedly connected to the mobile platform, a support block is fixedly connected to the top of the support frame, an inclined frame is fixedly connected to the top of the support block, and a side synchronous displacement spray dust removal mechanism is provided inside the support frame.

[0006] The side-mounted synchronous displacement spray dust removal mechanism includes a screw rotatably mounted inside a support frame. A displacement motor is fixedly installed at the top of the inner wall of the support frame, driving the screw to rotate. A threaded sleeve is threadedly connected to the outer wall of the screw. Connecting shafts are fixedly connected to the inner walls of both sides of the threaded sleeve. A connecting rod is rotatably connected to the outer wall of each connecting shaft. A linkage shaft is rotatably connected to the inner wall of the connecting rod away from the connecting shaft. An L-shaped block is fixedly connected to one end of the linkage shaft, and a displacement side spray pipe is fixedly connected to one side of the L-shaped block. A connecting rotating block is fixedly connected to the bottom end of the displacement side spray pipe, and a linkage rotating rod is fixedly installed on the inner wall of the connecting rotating block. A front-to-back synchronous displacement spray dust removal mechanism is installed inside the moving platform near the support block. A top synchronous displacement spray dust removal assembly is provided inside the inclined frame.

[0007] Preferably, the threaded sleeve and the support frame are slidably connected, and the two connecting shafts are symmetrically arranged about the middle of the threaded sleeve. A hinge block is rotatably connected to one side of the sleeve-shaped rotating block, and the hinge block is fixedly connected to the support frame. A first angle sensor is fixedly installed at one end of the linkage rotating rod; the first angle sensor is fixedly connected to the hinge block. Multiple spray pipes are fixedly connected to one side of the outer wall of the displacement-side spray pipe, and two spray heads are fixedly connected to one end of each spray pipe. A concave hose is installed on the other side of the outer wall of the displacement-side spray pipe, and both displacement-side spray pipes are fixedly connected to the concave hose. A connecting pipe is fixedly connected to the bottom end of the concave hose, and the connecting pipe is fixedly connected to the moving platform. A valve is threadedly connected to the top end of the connecting pipe, and the valve is fixedly connected to the water tank. A battery is provided on the other side of the moving platform, and the battery is fixedly connected to the moving platform. A controller is embedded in one side of the battery. A booster fan is fixedly connected to the top of the moving platform; a threaded cover is provided on one side of the booster fan, and the threaded cover is threadedly connected to the water tank.

[0008] In this technology, during the spray cooling and dust removal process in building construction, the displacement motor drives the screw to rotate forward. The screw drives the threaded sleeve to move downward under the action of the thread transmission force. The connecting shaft drives the top of the sleeve rod to move downward, and the linkage shaft drives the L-shaped block to rotate clockwise. In this way, the L-shaped block causes the displacement side spray pipe to rotate clockwise. The sleeve rotating block drives the linkage rotating rod to rotate clockwise, and the linkage rotating rod rotates clockwise inside the hinge block. Simultaneously, another displacement-side nozzle rotates counterclockwise, causing the two spray heads to rotate clockwise. This allows multiple spray heads on the displacement-side nozzle to rotate clockwise for dust removal, while the other displacement-side nozzle rotates counterclockwise for dust removal. When the angle value sensed by the first angle sensor matches the 90-degree value set by the controller, the controller activates the screw, causing the threaded sleeve to move upward under the force of the threaded transmission. The connecting shaft then moves the top of the sleeve rod upward, while the linkage shaft rotates the L-shaped block counterclockwise. The displacement-side nozzle then rotates the sleeve rotating block counterclockwise, and the linkage rod rotates counterclockwise inside the hinge block. The spray pipe drives the two spray heads to rotate counterclockwise, allowing multiple spray heads on the displacement-side nozzle to rotate counterclockwise for dust removal, while the other displacement-side nozzle rotates clockwise for dust removal.

[0009] Preferably, the front and rear synchronous displacement spray dust removal mechanism includes a linkage rotating tube rotatably disposed inside the mobile platform and near the support block; both ends of the linkage rotating tube are fixedly connected to displacement rotating tubes, and one side of each displacement rotating tube is fixedly connected to multiple displacement nozzles. A second angle sensor is provided below each displacement nozzle, and the output end of the second angle sensor is fixedly connected to the displacement rotating tube; the center point of the output end of the second angle sensor and the center point of the linkage rotating tube are on the same horizontal line, and a linkage gear is fixedly connected to the outer wall of the linkage rotating tube, and a drive gear is meshed with the outer wall of the linkage gear.

[0010] A rotating shaft is fixedly connected to the inner wall of the drive gear, and a reduction motor is fixedly installed at one end of the rotating shaft. A support frame is fixedly connected to the upper surface of the reduction motor, and a protective shell is fixedly connected to one side of the inner wall of the support frame. The protective shell is fixedly connected to the support block. A conveying hose is provided on one side of the support block, and the linkage rotating pipe and the water tank are both fixedly connected to the conveying hose. The second angle sensor is fixedly connected to the tilting frame, and the two displacement rotating pipes are symmetrically arranged about the linkage rotating pipe.

[0011] In this technology, during construction spray cooling and dust removal, the geared motor drives the rotating shaft in reverse, causing the drive gear to engage and rotate counterclockwise. This, in turn, causes the linkage gear to rotate 340 degrees counterclockwise, which in turn causes two displacement rotating tubes to rotate 340 degrees counterclockwise. These displacement rotating tubes then rotate multiple displacement nozzles 340 degrees counterclockwise for dust removal. When the angle value sensed by the second angle sensor matches the 340-degree angle value set by the controller, the controller activates the geared motor to drive the rotating shaft clockwise. This causes the drive gear to engage and rotate clockwise, and the linkage rotating tube rotates 340 degrees clockwise inside the support block. The displacement rotating tubes then rotate multiple displacement nozzles 340 degrees clockwise for dust removal.

[0012] Preferably, the top synchronous displacement spray dust removal assembly includes a bidirectional screw rotatably disposed inside an inclined frame; the outer wall of the bidirectional screw has two opposite and symmetrical threads, and a linkage motor is fixedly installed at one end of the bidirectional screw, which is fixedly connected to the inclined frame. Two threaded sleeve blocks are threadedly connected to the outer wall of the bidirectional screw, and both threaded sleeve blocks are slidably connected to the inclined frame. A displacement distance sensor is provided on one side of one of the threaded sleeve blocks, and the displacement distance sensor is fixedly connected to the inclined frame. A top spray inclined pipe is fixedly connected to the inner wall of each threaded sleeve block, and multiple top spray heads are fixedly connected to the top of the outer wall of each top spray inclined pipe. A connecting hose is fixedly connected to the top of each top spray inclined pipe; both connecting hoses are fixedly connected to a water tank. The linkage motor drives the bidirectional screw to rotate, and the multiple top spray heads are arranged equidistantly from top to bottom.

[0013] In this technology, during construction spraying for cooling and dust removal, a linkage motor drives a bidirectional screw to rotate forward. The bidirectional screw causes two threaded coupling blocks to move away from each other under the force of the threaded transmission. This causes multiple top spray nozzles on the inclined top spray pipe to move to the right for dust removal, while multiple nozzles on the other inclined top spray pipe can move to the left for dust removal. When the distance value sensed by the displacement sensor matches the displacement distance set by the controller, the controller activates the bidirectional screw to rotate in reverse. The bidirectional screw then causes the two threaded coupling blocks to move closer together under the force of the threaded transmission. Multiple nozzles on the inclined top spray pipe can move to the left for dust removal, while multiple nozzles on the other inclined top spray pipe can move to the right for dust removal.

[0014] The technical effects and advantages of this invention are as follows: 1. This invention utilizes a side-mounted synchronous displacement spray dust removal mechanism. A displacement motor drives a screw to rotate clockwise, which in turn moves a threaded sleeve downwards under the influence of threaded transmission force. This threaded sleeve then moves two connecting shafts downwards synchronously. Multiple spray heads on the displacement-side spray pipe rotate clockwise for dust removal, while multiple spray heads on the other displacement-side spray pipe rotate counter-clockwise for dust removal. When the angle value sensed by the first angle sensor matches the 90-degree value set by the controller, the controller activates the screw to move the threaded sleeve upwards under the influence of threaded transmission force. This allows multiple spray heads on the displacement-side spray pipe to rotate counter-clockwise for dust removal, while multiple spray heads on the other displacement-side spray pipe rotate clockwise for dust removal. Simultaneously, the water is cooled, enabling the two displacement-side spray pipes to perform synchronous displacement spray dust removal from the side. This results in a wider dust removal contact and separation area, significantly improving the dust removal separation effect.

[0015] 2. This invention utilizes a front-to-back synchronous shifting spray dust removal mechanism. A reduction motor drives the rotating shaft to reverse, which in turn drives the linkage gear to rotate counterclockwise. The linkage gear then drives the linkage rotating tube to rotate 340 degrees counterclockwise. The shifting rotating tube drives multiple shifting nozzles to rotate 340 degrees counterclockwise for spray dust removal. When the angle value sensed by the second angle sensor matches the 340-degree angle value set by the controller, the controller activates the reduction motor to drive the rotating shaft to rotate clockwise. The shifting rotating tube then drives multiple shifting nozzles to rotate 340 degrees clockwise for spray dust removal. This allows the multiple shifting nozzles on the two shifting rotating tubes to achieve front-to-back synchronous shifting spray dust removal, resulting in a wider spray dust removal separation contact area and significantly improved spray dust removal separation effect.

[0016] 3. This invention utilizes a top synchronous displacement spray dust removal assembly. A linkage motor drives a bidirectional screw to rotate forward. The bidirectional screw causes two threaded sleeve blocks to move away from each other under the action of thread transmission force. The top spray tilting pipe drives multiple top spray nozzles to move to the right for dust removal, while multiple top spray nozzles on the other top spray tilting pipe can move to the left for dust removal. When the distance value sensed by the displacement distance sensor is the same as the displacement distance set by the controller, the controller starts the bidirectional screw to reverse. Multiple top spray nozzles on the top spray tilting pipe can move to the left for dust removal, while multiple top spray nozzles on the other top spray tilting pipe can move to the right for dust removal. This enables the two top spray tilting pipes to achieve top synchronous displacement spray dust removal, resulting in a wider spray dust removal separation contact area and significantly improving the spray dust removal separation effect.

[0017] Based on the interaction of the above-mentioned multiple functions, firstly, multiple spray heads on the two displacement side nozzles can simultaneously perform displacement spraying and dust removal on the sides; simultaneously, multiple displacement nozzles on the two displacement rotary pipes can achieve simultaneous displacement spraying and dust removal at the front and rear; and simultaneously, the two top-spray inclined pipes can achieve simultaneous displacement spraying and dust removal at the top. In summary, simultaneous displacement spraying and dust removal can be achieved on the sides, front and rear, and top inclined surfaces, resulting in a wider contact area between the sprayed water and airborne dust, significantly improving the dust removal and separation effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] As attached Figure 1 - Appendix Figure 10 The invention relates to a spray cooling and dust removal device for building construction. This device includes a side synchronous displacement spray dust removal mechanism, a front and rear synchronous displacement spray dust removal mechanism, and a top synchronous displacement spray dust removal component. The arrangement of these mechanisms and components allows for synchronous displacement spray dust removal on the sides, front and rear, and the top inclined surface, resulting in a wider contact area between the sprayed water and airborne dust, significantly improving the dust removal effect. The specific structural configuration of each mechanism and component is as follows.

[0031] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 3As shown, the water tank 2 is located above the mobile platform 1, and the support frame 3 is located on one side of the water tank 2. The support frame 3 is fixedly connected to the mobile platform 1. The top of the support frame 3 is fixedly connected to the support block 4, and the top of the support block 4 is fixedly connected to the inclined frame 5. The inside of the support frame 3 is provided with a side synchronous displacement spray dust removal mechanism. The side synchronous displacement spray dust removal mechanism includes a screw 6 rotatably installed inside the support frame 3. A displacement motor 7 is fixedly installed on the top of the inner wall of the support frame 3. The displacement motor 7 is used to drive the screw 6 to rotate. The outer wall of the screw 6 is threadedly connected to a threaded sleeve 8. The inner walls on both sides of the threaded sleeve 8 are fixedly connected to connecting shafts 9.

[0032] A linkage shaft 11 is rotatably connected to the inner wall of the sleeve rod 10 away from the connecting shaft 9. An L-shaped block 12 is fixedly connected to one end of the linkage shaft 11, and a displacement side nozzle 13 is fixedly connected to one side of the L-shaped block 12. A sleeve rotating block 44 is fixedly connected to the bottom end of the displacement side nozzle 13. A linkage rotating rod 14 is fixedly installed on the inner wall of the sleeve rotating block 44. A front and rear synchronous displacement spray dust removal mechanism is installed inside the moving platform 1 near the support block 4. A top synchronous displacement spray dust removal component is provided inside the inclined frame 5.

[0033] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 4 As shown, a hinge block 15 is rotatably connected to one side of the sleeve rotating block 44. The hinge block 15 is fixedly connected to the support frame 3. A first angle sensor 16 is fixedly installed at one end of the linkage rotating rod 14. The first angle sensor 16 is fixedly connected to the hinge block 15 so that the linkage rotating rod 14 can rotate clockwise inside the hinge block 15. The angle of the linkage rotating rod 14 is sensed by the first angle sensor 16. When the angle value sensed by the first angle sensor 16 is the same as the ninety-degree value set by the controller 23, the controller 23 starts the screw 6 to drive the threaded sleeve 8 to move upward under the action of the thread transmission force.

[0034] Multiple spray pipes 17 are fixedly connected to one side of the outer wall of the displacement side spray pipe 13. Two spray heads 18 are fixedly connected to one end of each spray pipe 17. A concave hose 19 is installed on the other side of the outer wall of the displacement side spray pipe 13. Both displacement side spray pipes 13 are fixedly connected to the concave hose 19. A connecting pipe 20 is fixedly connected to the bottom end of the concave hose 19. The connecting pipe 20 is fixedly connected to the moving platform 1. A valve 21 is threadedly connected to the top end of the connecting pipe 20. The valve 21 is fixedly connected to the water tank 2 so that the controller 23 can open the valve 21 and divert water through the displacement side spray pipe 13 into the multiple spray pipes 17. The water is then poured into the two spray heads 18 through the spray pipes 17. The spray heads 18 then atomize and spray the water, allowing the water to come into contact with dust in the air. A battery 22 is provided on the other side of the mobile platform 1, and the battery 22 is fixedly connected to the mobile platform 1; a controller 23 is embedded on one side of the battery 22 so that the battery 22 can power the controller 23, and the controller 23 can start the displacement motor 7 to realize the drive operation of the displacement motor 7.

[0035] A booster fan 24 is fixedly connected to the top of the mobile platform 1; a threaded cover 25 is provided on one side of the booster fan 24, and the threaded cover 25 is threadedly connected to the water tank 2 so that the threaded cover 25 and the water tank 2 can be separated by threads so that water can be poured into the water tank 2. The controller 23 starts the booster fan 24, and the booster fan 24 pressurizes the water inside the water tank 2.

[0036] In this embodiment, as shown in the appendix Figure 5 - Appendix Figure 7 As shown, the front and rear synchronous displacement spray dust removal mechanism includes a linkage rotating pipe 26 rotatably installed inside the mobile platform 1 and near the support block 4; both ends of the linkage rotating pipe 26 are fixedly connected to displacement rotating pipes 27, and one side of each displacement rotating pipe 27 is fixedly connected to multiple displacement nozzles 28. A second angle sensor 29 is provided below the displacement nozzle 28, and the output end of the second angle sensor 29 is fixedly connected to the displacement rotating pipe 27; the center point of the output end of the second angle sensor 29 is on the same horizontal line as the center point of the linkage rotating pipe 26, and a linkage gear 30 is fixedly connected to the outer wall of the linkage rotating pipe 26, and a drive gear 31 is meshed and driven to the outer wall of the linkage gear 30.

[0037] A rotating shaft 32 is fixedly connected to the inner wall of the drive gear 31, and a reduction motor 33 is fixedly installed at one end of the rotating shaft 32. A support frame 35 is fixedly connected to the upper surface of the reduction motor 33. A protective shell 34 is fixedly connected to one side of the inner wall of the support frame 35, and the protective shell 34 is fixedly connected to the support block 4. A conveying hose 36 is provided on one side of the support block 4, and the linkage rotating pipe 26 and the water tank 2 are both fixedly connected to the conveying hose 36. The second angle sensor 29 is fixedly connected to the tilting frame 5, and the two displacement rotating pipes 27 are symmetrically arranged about the linkage rotating pipe 26.

[0038] In this embodiment, as shown in the appendix Figure 8 - Appendix Figure 10 As shown, the top synchronous displacement spray dust removal assembly includes a bidirectional screw 38 rotatably disposed inside the inclined frame 5; the outer wall of the bidirectional screw 38 has two opposite and symmetrical threads, and a linkage motor 37 is fixedly installed at one end of the bidirectional screw 38. The linkage motor 37 is fixedly connected to the inclined frame 5, and two threaded sleeve blocks 39 are threadedly connected to the outer wall of the bidirectional screw 38. Both threaded sleeve blocks 39 are slidably connected to the inclined frame 5.

[0039] A displacement distance sensor 40 is provided on one side of one of the threaded socket blocks 39, and the displacement distance sensor 40 is fixedly connected to the tilting frame 5. A top spray tilting pipe 41 is fixedly connected to the inner wall of each threaded socket block 39. Multiple top spray nozzles 42 are fixedly connected to the top of the outer wall of the top spray tilting pipe 41, and a connecting hose 43 is fixedly connected to the top of each top spray tilting pipe 41. Both connecting hoses 43 are fixedly connected to the water tank 2. The linkage motor 37 is used to drive the bidirectional screw 38 to rotate, and the multiple top spray nozzles 42 are arranged equidistantly from top to bottom.

[0040] The working principle of the spray cooling and dust removal device for building construction of the present invention is as follows: First, when the present invention is moved and placed, in the presence of air pollution, rotating the threaded cap 25 forward will disengage the threads between the threaded cap 25 and the water tank 2, allowing water to be poured into the water tank 2. After filling, rotating the threaded cap 25 backward will reconnect the threads between the threaded cap 25 and the water tank 2, thereby sealing and fixing the water tank 2. By pushing the moving platform 1, which drives multiple wheels to move, the moving platform 1 moves the connecting pipe 20, causing the valve 21 to move. The valve 21 then moves the water tank 2, allowing the water tank 2 to be moved to the cooling and dust removal site at the construction site.

[0041] Secondly, when performing side synchronous displacement spray dust removal, the present invention powers the controller 23 via the battery 22. The controller 23 starts the booster fan 24, which pressurizes the water inside the water tank 2. The controller 23 opens the valve 21, and the water inside the water tank 2 is pressurized into the connecting pipe 20. After being pressurized, the water inside the water tank 2 enters the concave hose 19 through the connecting pipe 20. The concave hose 19 then distributes the water to the two displacement side spray pipes 13. The displacement side spray pipes 13 distribute the water to multiple spray pipes 17, which then pour the water into the two spray heads 18. In this way, the spray heads 18 atomize and spray the water, allowing the water to come into contact with the dust in the air, achieving the separation of dust particles and thus achieving dust removal. At the same time, it can also cool the air.

[0042] The positioner motor 7 is activated by the controller 23, which drives the screw 6 to rotate clockwise. The screw 6 then moves the threaded sleeve 8 downwards. The threaded sleeve 8 moves the two connecting shafts 9 downwards synchronously, and the connecting shafts 9 move the upper end of the sleeve rod 10 downwards. Since the length of the sleeve rod 10 is fixed, its lower end swings away from the support frame 3 via the linkage shaft 11 (from the perspective of viewing from the outside to the inside of the device, the left linkage shaft 11 swings counterclockwise, and the right linkage shaft 11 swings clockwise). The linkage shaft 11 drives the L-shaped block 12 to swing synchronously, thereby causing the two positioner-side nozzles 13 to rotate outwards around the linkage rod 14 at their bottom ends. Specifically, the left positioner-side nozzle 13 rotates counterclockwise, and the right positioner-side nozzle 13 rotates clockwise. During the rotation, the displacement side nozzle 13 drives the spray pipe 17 and the spray head 18 to rotate synchronously, so that the left spray head 18 sweeps counterclockwise and the right spray head 18 sweeps clockwise, thereby achieving synchronous displacement spray dust removal on both sides.

[0043] When the first angle sensor 16 detects that the rotation angle of the linkage rod 14 reaches a preset value (e.g., 90 degrees), the controller 23 controls the positioner motor 7 to reverse, and the screw 6 drives the threaded sleeve 8 to move upward. The above movements are reversed, and the two positioner side spray pipes 13 swing inward. This process is repeated, causing the spray head to swing back and forth on the side, expanding the spray coverage area.

[0044] The angle of the linkage rod 14 is sensed by the first angle sensor 16. When the angle value sensed by the first angle sensor 16 is the same as the 90-degree value set by the controller 23, the controller 23 starts the screw 6 to drive the threaded sleeve 8 to move upward under the action of the thread transmission force. In this way, the threaded sleeve 8 drives the two connecting shafts 9 to move upward synchronously. The connecting shafts 9 drive the top of the sleeve rod 10 to move upward, and the sleeve rod 10 drives the linkage shaft 11 to rotate counterclockwise. At the same time, the linkage shaft 11 drives the L-shaped block 12 to rotate counterclockwise. The L-shaped block 12 drives the displacement side nozzle 13 to rotate counterclockwise. The displacement side nozzle 13 drives the sleeve rotating block 44 to rotate counterclockwise. The sleeve rotating block 44 drives the linkage rod 14 to rotate counterclockwise. The linkage rod 14 rotates counterclockwise inside the hinge block 15. Simultaneously, the displacement-side nozzle 13 drives multiple spray pipes 17 to rotate counterclockwise, and the spray pipes 17 drive two spray heads 18 to rotate counterclockwise. This allows the multiple spray heads 18 on the displacement-side nozzle 13 to rotate counterclockwise for dust removal, while the multiple spray heads 18 on the other displacement-side nozzle 13 can rotate clockwise for dust removal. When the angle detected by the first angle sensor 16 does not reach the set 90 degrees, the controller 23 controls the displacement motor 7 to continue driving the screw 6 to rotate clockwise. Thus, with the continuous forward and reverse driving of the displacement motor 7, the two displacement-side nozzles 13 can synchronously perform displacement-side spraying for dust removal from the side, resulting in a wider dust removal contact area and better dust separation effect.

[0045] Simultaneously, when the present invention performs front and rear synchronous displacement spray dust removal, the water inside the water tank 2 is pressurized and enters the delivery hose 36, which in turn pressurizes the water and enters the linkage rotating pipe 26. The water is then diverted from the linkage rotating pipe 26 to two displacement rotating pipes 27, which in turn divert the water into multiple displacement nozzles 28. The multiple displacement nozzles 28 on the displacement rotating pipe 27 enable the water to spray forward for dust removal, while the multiple displacement nozzles 28 on the other displacement rotating pipe 27 enable the water to spray backward for dust removal.

[0046] The protective shell 34 is supported by the support block 4, which provides support to the support frame 35. Simultaneously, the protective shell 34 protects the drive gear 31 from external damage. This causes the reduction motor 33 to drive the rotating shaft 32 in reverse, which in turn drives the drive gear 31 in reverse. The drive gear 31 then drives the linkage gear 30 to rotate counter-clockwise. The linkage gear 30 drives the linkage tube 26 to rotate 340 degrees counter-clockwise within the support block 4. Simultaneously, the linkage tube 26 drives two displacement tubes 27 to rotate 340 degrees counter-clockwise, which in turn drives multiple displacement nozzles 28 to rotate 340 degrees counter-clockwise for dust suppression spraying.

[0047] The second angle sensor 29 senses the angle of the displacement tube 27. When the angle value sensed by the second angle sensor 29 is the same as the 340-degree angle value set by the controller 23, the controller 23 starts the reduction motor 33 to drive the rotating shaft 32 to rotate clockwise. The rotating shaft 32 drives the drive gear 31 to rotate clockwise, and the drive gear 31 drives the linkage gear 30 to rotate clockwise. The linkage gear 30 drives the linkage tube 26 to rotate clockwise 340 degrees. The linkage tube 26 rotates clockwise 340 degrees inside the support block 4. At the same time, the linkage tube 26 drives the two displacement tubes 27 to rotate clockwise 340 degrees. The displacement tubes 27 drive the multiple displacement nozzles 28 to rotate clockwise 340 degrees to perform spray dust removal operation. As the reduction motor 33 continuously rotates in both directions, the multiple displacement nozzles 28 on the two displacement tubes 27 achieve synchronous front and rear displacement spray dust removal, resulting in a wider contact area for dust removal separation.

[0048] Meanwhile, when the present invention performs top synchronous displacement spray dust removal, the linkage motor 37 drives the bidirectional screw 38 to rotate forward. The bidirectional screw 38 drives the two threaded sleeve blocks 39 to move away from each other under the action of thread transmission force. In this way, the threaded sleeve block 39 drives the top spray tilting pipe 41 to move to the right, while the other threaded sleeve block 39 drives the other top spray tilting pipe 41 to move to the left. The top spray tilting pipe 41 drives multiple top spray heads 42 to move to the right to spray dust removal, while the multiple top spray heads 42 on the other top spray tilting pipe 41 can move to the left to spray dust removal.

[0049] Distance sensing is achieved through the displacement distance sensor 40 to the threaded sleeve block 39. When the distance value sensed by the displacement distance sensor 40 is the same as the displacement distance set by the controller 23, the controller 23 starts the bidirectional screw 38 to reverse. The bidirectional screw 38 drives the two threaded sleeve blocks 39 to move closer to each other under the action of thread transmission force. In this way, the threaded sleeve block 39 drives the top spray tilting pipe 41 to move to the left, and the other threaded sleeve block 39 drives the other top spray tilting pipe 41 to move to the right. The multiple top spray nozzles 42 on the top spray tilting pipe 41 can move to the left to spray dust, and the multiple top spray nozzles 42 on the other top spray tilting pipe 41 can move to the right to spray dust. At the same time, the water can be cooled. As the linkage motor 37 continuously rotates in both directions, the two top spray tilting pipes 41 achieve synchronous displacement spraying dust removal at the top, resulting in a wider spray dust removal separation contact area and a better effect in air pollution treatment.
