Description

Technical Field

[0001] This application relates to the field of environmental protection, and in particular to an intelligent linkage spray dust suppression device for construction sites. Background Technology

[0002] In fields such as construction, environmental management at construction sites is crucial. With the continuous development of the construction industry, the scale of construction sites is expanding, and construction activities are becoming increasingly frequent. This has made dust pollution at construction sites a key factor affecting the surrounding environment and the health of construction workers. Dust not only causes air pollution but can also trigger respiratory diseases and other health problems, negatively impacting the ecological environment and social life. Therefore, effectively controlling dust at construction sites has become a critical issue that the construction industry urgently needs to address.

[0003] Traditional methods for controlling dust at construction sites typically include regularly spraying water with water trucks, which are manually operated to spray water on the construction site and surrounding roads to reduce the concentration of dust in the air. Additionally, fixed spray dust suppression equipment is installed at fixed locations on the construction site to continuously spray dust. Another method is to use fencing to block the spread of dust, setting up barriers around the construction site to reduce the area from which dust can spread outwards.

[0004] Regarding the technologies mentioned above, water trucks require manual operation for regular dust suppression, resulting in low efficiency and difficulty in precisely controlling the spray location and water volume, potentially leading to water waste. Fixed spray dust suppression equipment can only spray from a fixed location, unable to flexibly adjust the spray position and direction according to actual dust conditions. For construction sites with significant dust concentration fluctuations, it cannot effectively and promptly address dust control. While construction site barriers can block dust spread to some extent, they cannot effectively suppress existing dust and cannot fundamentally solve the dust problem. Summary of the Invention

[0005] In order to accurately reduce dust, improve efficiency, and reduce water waste, this application provides an intelligent linkage spray dust suppression device for construction sites.

[0006] This application provides an intelligent linkage spray dust suppression device for construction sites, which adopts the following technical solution: A smart, interconnected spray dust suppression device for construction sites includes a spray device, a dust monitoring system, a mobile box, a mobile track, and a control system. The spray device is located inside the mobile box, and a spray nozzle is provided on the side wall of the mobile box near the output end of the spray device. A baffle is hinged to the outside of the mobile box to block the spray nozzle. The mobile track is set along the side of the construction site, and the mobile box is rotatably connected to the top of the mobile track. The spray device is connected to a water inlet pipe, and a water supply pipe is fixed to the mobile track. The water inlet pipe and the water supply pipe can be automatically detached and connected. The dust monitoring system is used to predict the dust diffusion range and concentration changes of the construction site within a preset time period. The control system is used to control the spray device to move to the predicted position and perform spray dust suppression based on the prediction results of the dust monitoring system.

[0007] By adopting the above technical solution, the dust monitoring system can predict the dust diffusion range and concentration changes at the construction site within a preset time period. Based on the prediction results, the control system controls the spraying device to move to the predicted position for dust suppression, achieving precise dust reduction, improving work efficiency, and reducing manual intervention. The spraying device is located in a mobile box, which is rotatably connected to a moving track set along the side of the construction site, allowing it to be flexibly moved to the location where dust suppression is needed. The water inlet pipe and water supply pipe can be automatically disassembled and connected, facilitating the spraying device to obtain water during movement and precisely controlling water resource usage. The baffle hinged to the outside of the mobile box can cover the spray nozzle, reducing maintenance difficulty, enhancing safety, and improving the overall intelligence level of the equipment.

[0008] Optionally, the spraying device includes a fog cannon, a base, and a first electric push rod. The base is fixedly connected to the movable box, the cylinder of the first electric push rod is rotatably connected to the fog cannon, the output end of the first electric push rod is rotatably connected to the base, the water inlet pipe is connected to the fog cannon, and a support frame is fixedly provided on the upper surface of the base. The support frame is rotatably connected to both sides of the fog cannon in the horizontal direction at the middle position.

[0009] By adopting the above technical solution, the fog cannon can adjust its angle under the drive of the first electric push rod, so as to spray and suppress dust in the dusty area more accurately according to the actual dust situation at the construction site, and effectively improve the dust suppression effect.

[0010] Optionally, the spray nozzle is provided with a rotating frame, the output end of the fog cannon is fixedly connected to the rotating frame, the upper end of the rotating frame is rotatably connected to a connecting plate along the horizontal axis, the upper end of the connecting plate is rotatably connected to a movable box, the lower end of the rotating frame is rotatably connected to several movable blocks along the horizontal axis, and the baffle is provided with several sliding grooves corresponding to the movable blocks one by one, and the movable blocks are slidably connected to the baffle along the extension direction of the sliding grooves.

[0011] By adopting the above technical solution, when the spraying device is working, the output end of the fog cannon drives the rotating frame to rotate, and the moving block on the rotating frame slides in the groove of the baffle, so that the baffle can be opened smoothly, ensuring that the spraying device can spray and suppress dust normally; at the same time, the connection method between the rotating frame and the connecting plate, and between the moving block and the groove, makes the fog cannon more stable during rotation, and can accurately adjust the direction and angle of the spray, thereby more effectively suppressing dust at the construction site and improving the dust suppression effect.

[0012] Optionally, the water supply pipeline includes several pipes connected end to end in sequence, and the moving track includes several sets of slide rails connected end to end in sequence. The number of pipes and slide rails are the same and they are fixedly connected in a one-to-one correspondence. Each pipe is fixedly provided with a first connecting pipe on its upper side, and the water inlet pipe is detachably connected to the first connecting pipe.

[0013] By adopting the above technical solution, water supply pipelines and mobile tracks can be flexibly assembled according to the actual layout of the construction site, making it easy to adapt to construction sites of different shapes and sizes. The detachable connection between the water inlet pipe and the first connecting pipe allows the spraying device to connect to the water supply pipeline at any time during movement to obtain a water source, ensuring the continuous operation of the spray dust suppression operation. It can also be quickly disassembled when needed, facilitating equipment maintenance and replacement, improving the flexibility and convenience of equipment use, accurately controlling water resource usage, reducing maintenance difficulty, and enhancing the overall intelligence level of the equipment.

[0014] Optionally, the water inlet pipe includes a second connecting pipe, a first flexible hose, a fixed cylinder, a rotating cylinder, and a second flexible hose. The fixed cylinder is fixedly connected inside the movable box. One end of the first flexible hose is fixedly connected to the second connecting pipe. The end of the first flexible hose away from the second connecting pipe is connected to the outer wall of the rotating cylinder. The end of the second connecting pipe away from the first flexible hose passes through the side wall of the movable box and is detachably connected to the first connecting pipe. One end of the second flexible hose is coaxially fixedly connected to the fixed cylinder. The other end of the second flexible hose is connected to the spraying device. The first flexible hose is wound around the outer wall of the rotating cylinder. The rotating cylinder is coaxially rotatably connected to the outside of the fixed cylinder. The fixed cylinder has a water inlet, and the fixed cylinder is connected to the first flexible hose through the water inlet.

[0015] By adopting the above technical solution, the length and position of the water inlet pipe can be flexibly adjusted during the movement of the spraying device, ensuring a stable water supply in different locations and avoiding damage to the water pipe caused by movement. At the same time, it facilitates the connection and disassembly of the water inlet pipe and the water supply pipeline, improving the flexibility and stability of the equipment, thereby increasing work efficiency, reducing manual intervention, accurately controlling water resource use, reducing maintenance difficulty, enhancing safety, and improving the overall intelligence level of the equipment.

[0016] Optionally, a retaining ring is coaxially fixed to the outer wall of the fixed cylinder, and a spring is fixed between the inner wall of the rotating cylinder and the outer wall of the fixed cylinder. The retaining ring is located between the water inlet and the spring, and the outer wall of the retaining ring is rotatably and sealingly connected to the inner wall of the rotating cylinder.

[0017] By adopting the above technical solutions, the retaining ring effectively prevents water from entering the area where the spring is located from the inlet, avoiding rust or damage to the spring due to water contact and extending its service life. The retaining ring ensures a tight seal when the rotating cylinder rotates relative to the fixed cylinder, preventing water leakage. The spring provides a rewinding force after the inlet pipe is stretched, allowing it to automatically rewind when stretching is no longer needed. This facilitates the storage and organization of the inlet pipe, reduces its space occupation at the construction site, and improves the cleanliness and safety of the construction site.

[0018] Optionally, the end of the second connecting tube away from the first flexible tube is slidably connected to an insertion tube in a vertical direction. The movable box is provided with a second electric push rod for driving the insertion tube to slide. The insertion tube is used to insert into the first connecting tube. The side wall of the insertion tube has a through hole communicating with the second connecting tube. The side wall of the first connecting tube is fixedly provided with a first locking plate. The side wall of the insertion tube is fixedly provided with a second locking plate. The first locking plate is threaded with a hexagonal bolt. The end of the first locking plate away from the second locking plate is rotatably connected to a rotating cylinder. The hexagonal bolt is slidably connected to the inside of the rotating cylinder along the axis. The second limiting rod has a limiting hole through which the screw end of the hexagonal bolt passes. The movable box is fixedly provided with a limiting motor. The output end of the limiting motor is coaxially fixedly provided with a first bevel gear. The outside of the movable box is rotatably connected with a second bevel gear that meshes with the first bevel gear. The second bevel gear is coaxially fixedly connected with a first gear. The end of the rotating cylinder away from the first locking plate is coaxially fixedly connected with a second gear that meshes with the first gear. The first gear is located above both the second gear and the first locking plate.

[0019] By adopting the above technical solution, the second electric push rod drives the insertion tube to slide, and the through hole of the insertion tube communicates with the second connecting tube, allowing the insertion tube to be smoothly inserted into the first connecting tube, thus connecting the water inlet pipe and the water supply pipe. The limit motor drives the first bevel gear to rotate, which in turn drives the meshing second bevel gear to rotate, thereby causing the coaxially fixed first gear to rotate. The first gear drives the second gear to rotate, causing the hexagonal bolt to slide along the axis and pass through the limit hole of the second limit rod, achieving reliable fixation of the insertion tube and the first connecting tube, ensuring the stability and sealing of the connection, guaranteeing the normal operation of the water supply process, thereby precisely controlling the use of water resources and improving the reliability and efficiency of the intelligent linkage spray dust suppression device at the construction site.

[0020] Optionally, a limiting plate is fixed to the outer wall of the second connecting pipe. The limiting plate is used to prevent the end of the second connecting pipe away from the first flexible hose from entering the interior of the moving box. In the initial state of the spring, the limiting plate is in contact with the outer wall of the moving box.

[0021] By adopting the above technical solution, when the spring is in its initial state, the limiting plate is in contact with the outer wall of the moving box, ensuring the position of the insertion tube, ensuring the connection stability and normal use of the water inlet pipe, and ensuring the smooth water supply of the spray device.

[0022] Optionally, a lifting ring is fixedly provided on the outer side wall of the upper end of the insertion tube, and a lifting frame is fixedly provided at the output end of the second electric push rod. The lifting ring is inserted into the lifting frame and is slidably connected to the lifting frame along the moving direction of the moving box. The lifting frame is used to drive the lifting ring to rise and fall.

[0023] By adopting the above technical solution, the second electric push rod drives the lifting frame to move vertically to a position flush with the lifting ring. The movement of the moving box causes the lifting ring to be inserted into the lifting frame. Then, the insertion and removal of the insertion tube and the first connecting tube are realized by the lifting and lowering of the output end of the second electric push rod. This enables precise control of the connection and disconnection of the water inlet pipe and the water supply pipe, achieving automatic connection and disassembly, reducing manual intervention, improving work efficiency, and precisely controlling the use of water resources, reducing maintenance difficulty, enhancing the safety of equipment use, and improving the overall intelligence level of the equipment.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The dust monitoring system can predict the dust diffusion range and concentration changes at the construction site within a preset time period. Based on this prediction, the control system moves the spraying device to the predicted location for dust suppression, achieving precise dust reduction, improving work efficiency, and reducing manual intervention. The spraying device is located in a mobile box, which is rotatably connected to a moving track set along the side of the construction site, allowing it to be flexibly moved to the location where dust suppression is needed. The water inlet pipe and water supply pipe can be automatically detached and connected, facilitating the spraying device to obtain water during movement and precisely controlling water resource usage. The hinged baffle on the outside of the mobile box can cover the spray nozzles, reducing maintenance difficulty, enhancing safety, and improving the overall intelligence level of the equipment. 2. The fog cannon can adjust its angle under the drive of the first electric push rod, so as to spray the dust suppression area more accurately according to the actual dust situation at the construction site, effectively improving the dust suppression effect; 3. When the spraying device is working, the output end of the fog cannon drives the rotating frame to rotate. The moving block on the rotating frame slides in the groove of the baffle, so that the baffle can be opened smoothly, ensuring that the spraying device can spray and suppress dust normally. At the same time, the connection between the rotating frame and the connecting plate, and between the moving block and the groove, makes the fog cannon more stable during rotation, and can accurately adjust the direction and angle of the spray, thereby more effectively suppressing dust at the construction site and improving the dust suppression effect.

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] This application discloses an intelligent linkage spray dust suppression device for construction sites.

[0035] Reference Figure 1 A smart linkage spray dust suppression device for construction sites includes a spray device 1, a dust monitoring system, a mobile box 2, a mobile track, and a control system.

[0036] The dust monitoring system constructs a dust dispersion prediction model based on real-time dust concentration, wind speed and direction, and work process type to predict the dust dispersion range and concentration changes within a preset time period. The system includes several dust monitoring devices installed at the construction site. It incorporates a model training subunit and a dispersion prediction subunit. The model training subunit trains a dust dispersion prediction model adapted to different construction scenarios based on historical dust data, environmental parameters, and work process data from the construction site. The dispersion prediction subunit inputs real-time collected data into the dust dispersion prediction model and outputs the dust dispersion range, dispersion path, peak concentration, and arrival time within the next 10-30 minutes. The dust monitoring system can monitor multiple parameters, including PM2.5, PM10, noise, wind speed, wind direction, atmospheric pressure, air temperature and humidity, and TSP. The dust monitoring system can achieve regional linkage, monitor whether the monitoring data in the construction site area exceeds the standard in real time, and send the data to the control system in real time. When the data is abnormal and triggers the warning threshold, the control system can respond quickly and control the spray device 1 to move to the predicted position and spray dust according to the prediction results of the dust monitoring system. In this way, dust suppression operations can be carried out accurately according to the actual dust situation, avoiding the blindness of traditional dust suppression methods, improving dust suppression efficiency, and reducing water waste.

[0037] Reference Figure 1 The mobile track is set along the side of the construction site. The mobile track includes several sets of slide rails 3 connected end to end in sequence. Adjacent slide rails 3 are detachably connected. Each set of slide rails 3 includes inner and outer rails. The mobile box 2 is rotatably connected to the upper end of the slide rail 3. The mobile box 2 is driven by electricity and is equipped with a battery to provide power.

[0038] Reference Figure 1 and Figure 2The spraying device 1 is located inside the mobile housing 2. The spraying device 1 includes a fog cannon 11, a base 12, and a first electric push rod 13. The base 12 is fixedly connected to the bottom of the mobile housing 2. A support frame 14 is fixedly mounted on the upper surface of the base 12. Rotating shafts are fixedly mounted on both sides of the fog cannon 11 along the horizontal direction at the middle position. Bearings corresponding to the rotating shafts are fixedly mounted on the upper end of the support frame 14. The rotating shafts pass through the bearings to achieve a rotatable connection between the fog cannon 11 and the support. The support frame 14 serves to assist in supporting the fog cannon 11, ensuring the stability of the fog cannon 11 during rotation. The fog cannon 11 is a common spraying device that can atomize water into fine particles, thereby effectively adsorbing dust in the air. The cylinder of the first electric push rod 13 is rotatably connected to the fog cannon 11, and the output end of the first electric push rod 13 is rotatably connected to the base 12. By extending and retracting the first electric push rod 13, the elevation angle of the fog cannon 11 can be adjusted, thereby changing the direction and range of the spray. The first electric actuator 13 consists of a motor, a lead screw, a nut, and other components. Its working principle is that the motor drives the lead screw to rotate, causing the nut to move linearly along the lead screw, thereby achieving the extension and retraction of the actuator. The first electric actuator 13 can also be replaced by other types of actuators, such as hydraulic actuators.

[0039] Reference Figure 3 The movable box 2 has a spray nozzle on its side wall near the output end of the spraying device 1. A baffle 21 is hinged to the outside of the movable box 2 to block the spray nozzle. When the fog cannon 11 is not in operation, the baffle 21 blocks the spray nozzle to prevent dust and debris from the construction site from entering the movable box 2. A rotating frame 22 is provided inside the spray nozzle. The output end of the fog cannon 11 is fixedly connected to the rotating frame 22. A connecting plate 23 is rotatably connected to the upper end of the rotating frame 22 along the horizontal axis. The upper end of the connecting plate 23 is rotatably connected to the movable box 2. Several moving blocks 24 are rotatably connected to the lower end of the rotating frame 22 along the horizontal axis. The baffle 21 has several sliding grooves 211 that correspond one-to-one with the moving blocks 24. The moving blocks 24 are slidably connected to the baffle 21 along the extension direction of the sliding grooves 211. When the fog cannon 11 is working, the rotating frame 22 rotates with the fog cannon 11. The sliding of the moving blocks 24 in the sliding grooves 211 causes the baffle 21 to open or close.

[0040] Reference Figure 1 A water supply pipeline is fixed between the two tracks of the moving track. The water supply pipeline consists of several pipes 5 connected end to end in sequence. The number of pipes 5 is the same as that of the slide rails 3, and they are fixedly connected one-to-one. The pipes 5 are connected by quick couplings. The water supply pipeline and moving track can be flexibly assembled according to the actual layout of the construction site, which is convenient to adapt to construction sites of different shapes and sizes. One section of pipe 5 is connected to an external water source, which can be water from a water tanker or a water tower. This section of pipe 5 is connected to a water pump, which provides power when supplying water to the fog cannon 11.

[0041] Reference Figure 4The fog cannon 11 is connected to a water inlet pipe 4, which provides water to the fog cannon 11. The water inlet pipe 4 includes a second connecting pipe 41, a first flexible hose 42, a fixed cylinder 43, a rotating cylinder 44, and a second flexible hose 45. Support plates are fixed at both ends of the fixed cylinder 43 and are fixedly connected to the inside of the movable box 2. The rotating cylinder 44 is coaxially rotatably connected to the outside of the fixed cylinder 43. The fixed cylinder 43 and the rotating cylinder 44 are located below the base 12.

[0042] Reference Figure 4 One end of the second hose 45 is connected to the fog cannon 11, and the other end of the second hose 45 is coaxially fixedly connected to the fixed cylinder 43. The fixed cylinder 43 has a water inlet 431. A retaining ring 46 is coaxially fixed to the outer wall of the fixed cylinder 43. The outer wall of the retaining ring 46 is rotatably connected to the inner wall of the rotating cylinder 44. The water inlet 431 is located between the retaining ring 46 and the second hose 45. One end of the first hose 42 is fixedly connected to the second connecting pipe 41. The end of the first hose 42 away from the second connecting pipe 41 is connected to the outer wall of the rotating cylinder 44. A first connecting pipe 51 is fixedly installed on the upper side of each pipe 5. The end of the second connecting pipe 41 away from the first hose 42 passes through the side wall of the movable box 2 and is detachably connected to the first connecting pipe 51. The fixed cylinder 43 is connected to the first hose 42 through the water inlet 431. When the fog cannon 11 is started, the water flows through the pipe 5, the first connecting pipe 51, the second connecting pipe 41, the first hose 42, the rotating cylinder 44, the fixed cylinder 43, and the second hose 45 in sequence, and then enters the fog cannon 11.

[0043] Reference Figure 5 A spring-loaded spring 47 is fixed between the inner wall of the rotating cylinder 44 and the outer wall of the fixed cylinder 43. A retaining ring 46 is located between the water inlet 431 and the spring-loaded spring 47. A limiting plate 411 is fixed to the outer wall of the second connecting pipe 41. The limiting plate 411 is used to prevent the end of the second connecting pipe 41 away from the first hose 42 from entering the interior of the moving box 2. In the initial state, the limiting plate 411 is in contact with the outer wall of the moving box 2. The retaining ring 46 plays a sealing and isolation role, preventing water from entering the area where the spring-loaded spring 47 is located. The first hose 42 is wound around the outer wall of the rotating cylinder 44. When the moving box 2 moves, the first hose 42 will unfold or wind up with the rotation of the rotating cylinder 44, ensuring that the length of the water inlet pipe 4 can adapt to the movement of the moving box 2. The spring-loaded spring 47 will undergo elastic deformation when the moving box 2 moves. When the moving box 2 returns to the initial position, the spring-loaded spring 47 will cause the rotating cylinder 44 to rotate, winding the first hose 42 back to the initial state.

[0044] Reference Figure 4 and Figure 6The second connecting pipe 41, at the end furthest from the first flexible hose 42, is vertically slidably connected to an insertion tube 48. The lower end of the insertion tube 48 is used to insert into the first connecting pipe 51, and a through hole 483 communicating with the second connecting pipe 41 is opened on the side wall of the insertion tube 48. A lifting ring 482 is fixedly provided on the outer side wall of the upper end of the insertion tube 48. The movable box 2 is provided with a second electric push rod 25 for driving the insertion tube 48 to slide, and a lifting frame 251 is fixedly provided at the output end of the second electric push rod 25. When water needs to be introduced, the movable box 2 moves to the nearest first connecting pipe 51, so that the insertion tube 48 is directly above the first connecting pipe 51. At this time, the lifting ring 482 is inserted into the lifting frame 251, and then the second electric push rod 25 pushes the lifting frame 251 down, thereby driving the insertion tube 48 to be inserted into the first connecting pipe 51. The movable box 2 can then be moved to the desired spraying location. The lifting frame 251 and the second electric push rod 25 move synchronously with the movable box 2. The lifting ring 482 slides into the lifting frame 251 along the moving direction of the movable box 2, and then the lifting ring 482 disengages from the lifting frame 251. When spraying is complete and the box needs to move to another area where the first connecting pipe 51 is located, the movable box 2 returns to the first connecting pipe 51 at this time, the lifting ring 482 re-inserts into the lifting frame 251, and the second electric push rod 25 drives the lifting frame 251 and the insertion pipe 48 to reset. The internal space of the lifting frame 251 is larger than the thickness of the lifting ring 482, improving the smoothness of their insertion.

[0045] Reference Figure 6 and Figure 7 A first locking plate 511 is fixed to the side wall of the first connecting tube 51, and a second locking plate 481 is fixed to the side wall of the insertion tube 48. The first locking plate 511 is threaded with a hexagonal bolt 512, and the second locking plate 481 has a limiting hole for the screw end of the hexagonal bolt 512 to pass through. During the insertion of the insertion tube 48 into the first connecting tube 51, the screw end of the hexagonal bolt 512 is aligned with the limiting hole. By rotating the hexagonal bolt 512, the screw end of the hexagonal bolt 512 is inserted into the limiting hole, which restricts the vertical displacement of the second locking plate 481 and fixes the insertion tube 48.

[0046] Reference Figure 6 and Figure 7 The first locking plate 511 is rotatably connected to a rotating cylinder 513 at one end away from the second locking plate 481. A hexagonal bolt 512 is slidably connected to the inside of the rotating cylinder 513 along the axis. The inside of the rotating cylinder 513 is a hexagonal through hole 483 corresponding to the hexagonal bolt 512. Rotating the rotating cylinder 513 can drive the hexagonal bolt 512 to rotate and slide inside the rotating cylinder 513.

[0047] Reference Figure 6 and Figure 7A limit motor 26 is fixedly installed inside the movable box 2. A first bevel gear 261 is coaxially fixed at the output end of the limit motor 26. A second bevel gear 262, which meshes with the first bevel gear 261, is rotatably connected to the outside of the movable box 2. A first gear 263 is coaxially fixedly connected to the second bevel gear 262. A second gear 514, which meshes with the first gear 263, is coaxially fixedly connected to the end of the rotating drum 513 away from the first locking plate 511. The first gear 263 is located above both the second gear 514 and the first locking plate 511. When the insertion tube 48 is inserted into the first connecting tube 51, the limit motor 26 drives the first bevel gear 261 to rotate. Through the transmission of the second bevel gear 262, the first gear 263, and the second gear 514, the hexagonal bolt 512 rotates and is inserted into the limit hole, thereby fixing the water inlet pipe 4 to the water supply pipe.

[0048] The implementation principle of the intelligent linkage spray dust suppression device for construction sites according to this application embodiment is as follows: The dust monitoring system monitors the dust situation at the construction site in real time, predicts the dust diffusion range and concentration changes within a preset time period, and transmits the information to the control system. Based on the prediction results, the control system controls the moving box 2 to move along the moving track to the predicted position. Upon reaching the position, the second electric push rod 25 drives the lifting ring 482 through the lifting frame 251, causing the insertion tube 48 to be inserted into the first connecting pipe 51. The limit motor 26, through gear transmission, causes the hexagonal bolt 512 to be inserted into the limit hole, connecting the water inlet pipe 4 to the water supply pipeline. Then, the spray device 1 starts working. The first electric push rod 13 adjusts the elevation angle of the fog cannon 11, and the fog cannon 11 sprays atomized water through the spray nozzle to suppress dust. During the movement of the moving box 2, the first flexible hose 42 unfolds or winds around the rotating cylinder 44, ensuring that the length of the water inlet pipe 4 can adapt to the movement of the moving box 2. After the spraying ends, the limit motor 26 rotates in the reverse direction, causing the hexagonal bolt 512 to disengage from the limit hole. The second electric push rod 25, through the lifting frame 251, drives the lifting ring 482 to pull the insertion tube 48 out of the first connecting tube 51, allowing the moving box 2 to continue moving to other positions. Compared with traditional dust suppression methods, this intelligent linkage spray dust suppression device can perform dust suppression operations more precisely, improve work efficiency, reduce manual intervention, accurately control water resource usage, reduce maintenance difficulty, enhance safety, and improve the overall intelligence level of the equipment.
