Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically a dust suppression device for use at construction sites. Background Technology

[0002] A construction site refers to the approved construction area and the place where people can carry out safe and civilized production and construction activities, including all areas on land, at sea, and in the air where construction work can be carried out, for industrial and civil projects such as building construction, civil engineering, equipment installation, and pipeline laying. The project manager is fully responsible for the on-site management of the construction process and should establish on-site management responsibilities and organize their implementation based on the project scale, technical complexity, and specific conditions of the construction site.

[0003] However, most existing construction sites rely on manual methods for dust suppression, and the ground at these sites often requires manual cleaning, resulting in low efficiency in dust reduction. Therefore, a new design was developed to address this issue. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a dust suppression device for construction sites, comprising a dust suppression device, wherein a spraying device is fixedly connected to the top of the dust suppression device; The dust suppression device includes a dust suppression housing with a spraying device on top. The spraying device sprays liquid onto the work area to suppress dust, directly wetting the dust particles and promoting their settling. This forms a physical barrier, intercepting dust diffusion, inhibiting secondary dust re-entrainment, improving dust suppression efficiency, reducing labor costs, improving the working environment, and ensuring production safety. The top of the dust suppression housing is fixedly connected to the bottom of the spraying device. A sliding plate is fixedly connected to the inner side of the dust suppression housing, sliding along a slide rail. The sliding plate causes the dust suppression housing to slide up and down. This serves to adjust the height of the equipment to meet different subsequent operational needs. A slide rail is slidably connected to the outer side of the sliding plate, and a dust-collecting base is fixedly connected to one side of the slide rail. Dust enters the dust-collecting base from the pneumatic mechanism. A guide plate is installed inside the dust-collecting base to guide the dust, increasing the flow speed of dust inside the equipment and reducing dust residue. The dust is collected by a collection housing for easy subsequent cleaning, ensuring continuous dust collection. A set of casters is fixedly connected to the bottom of the dust-collecting base for adjusting the equipment's position. The equipment is designed for support and movement, thereby increasing its range of motion and operational efficiency. A stabilizing mechanism is fixedly connected to the top edge of the caster set. This stabilizing mechanism, which is positioned on the caster set, contacts the ground, increasing the contact area and friction between the components and the ground. This improves the stability of the equipment, reduces vibration during operation, and enhances operational safety. It also provides a buffering effect, preventing component swaying from affecting equipment operation. A guide plate is fixedly connected to the top of the inner wall of the dust-suppressing base, and a collection shell is inserted into the outer side of the dust-suppressing base. A wind-driven mechanism generates airflow to absorb dust in the construction site, thus achieving dust suppression, protecting human health, reducing disease risks, improving air quality, reducing environmental pollution, and preventing excessive dust from affecting personnel. A wind-driven mechanism is fixedly connected to the outer side of the dust-suppressing shell. This mechanism changes the airflow direction, adapting to the spraying device. When the spraying device sprays liquid to suppress dust, the wind increases the spraying range, thereby increasing the efficiency of dust suppression and expanding the spraying area.

[0005] Preferably, the stabilizing mechanism includes a linear module, with a connecting block slidably connected to the inner side of the linear module. When the equipment moves to a designated position via the casters, the connecting block drives a telescopic rod to slide inside the linear module, causing the telescopic rod to contact the ground. This increases the contact area between the component and the ground, improving friction and thus enhancing the stability of the equipment. It also reduces vibration during operation, improves operational safety, and prevents the equipment from shaking and moving, which could affect its performance. A telescopic rod is fixedly connected to the outer side of the connecting block away from the linear module. When the equipment vibrates, the telescopic rod compresses the first spring. The compression mechanism acts as a shock absorber, reducing vibration impact and protecting core components of the equipment. Through elastic deformation or damping, it absorbs and dissipates vibration energy, preventing vibration from being directly transmitted to core components such as motors, pipes, nozzles, and control systems. This reduces loosening, wear, or breakage of components due to long-term vibration, improves equipment stability, ensures dust reduction, reduces noise pollution, improves the working environment, adapts to complex terrain, enhances equipment applicability, extends equipment life, reduces maintenance costs, and reduces impact load. It can reduce equipment failure rate and extend service life, thereby reducing the cost of repair and replacement of parts. A first spring is sleeved on the outer side of the telescopic rod.

[0006] Preferably, the pneumatic mechanism includes a pneumatic frame, with a pneumatic duct fixedly connected to one side of the frame. An axial flow fan rotates in the opposite direction, causing airflow from the duct towards the grid plate, thus breaking up localized air stagnation and accelerating dust diffusion or removal. Combined with a spraying device, this improves the contact efficiency between dust and water mist. During the spraying process, the pneumatic device increases the spraying range by using airflow, thereby increasing the efficiency of dust suppression and expanding the spraying area. An axial flow fan is fixedly connected to the inner wall of the pneumatic duct near the frame. The rotating axial flow fan absorbs dust from the area, which then enters the dust-collecting base through the pneumatic duct, thus achieving the goal of dust suppression. A grid plate is fixedly connected to the inner wall of the pneumatic duct on the side away from the axial flow fan. The grid plate serves to block external impurities from entering, preventing larger impurities from entering the duct and causing blockages, thus preventing any impact on equipment operation. A scraping mechanism is fixedly connected to the outer side of the grid plate. The wind power drives the scraping mechanism to rub against the surface of the grid plate, thereby cleaning dust from the surface of the components. This prevents debris from adhering to the surface of the components and reduces dust adsorption, thus preventing any impact on airflow. A scraper mechanism is fixedly connected to the middle of the inner wall of the pneumatic duct. The wind power drives the scraper mechanism to rotate, rubbing against the inner wall of the duct, thereby cleaning dust from the inner wall of the duct, reducing dust adsorption and retention, preventing any impact on subsequent airflow, and collecting any residual dust.

[0007] Preferably, the scraper mechanism includes a fixed frame. A receiving shaft is fixedly connected to the outside of the fixed frame near the axial flow fan. A rotating column is rotatably connected to the outside of the receiving shaft. A first blade is fixedly connected to the outside of the rotating column away from the grid plate. A scraper bracket is fixedly connected to the outside of the rotating column away from the first blade. A scraper plate is fixedly connected to the outside of the scraper bracket. The axial flow fan generates airflow, which acts on the surface of the first blade. The first blade drives the rotating column to rotate, causing the scraper bracket to control the scraper plate to rub against the inner wall of the pipe. This achieves the function of cleaning the inner wall of the pipe, thereby reducing dust adsorption and retention, avoiding affecting the subsequent airflow, collecting residual dust, preventing pipe blockage, ensuring smooth airflow, preventing secondary dust re-ignition or leakage, reducing the risk of pollution, protecting downstream equipment, and lowering the probability of failure.

[0008] Preferably, a connecting rod is fixedly connected between the opposite surfaces of the scraper bracket, and a second spring is sleeved on the outer side of the connecting rod. During the rotation and friction of the components, vibrations are easily generated. External force causes the connecting rod to compress and contract against the second spring, thereby playing a role in shock absorption and buffering, buffering impact force, avoiding damage caused by rigid collisions, absorbing impact energy, converting rigid collisions into flexible contact, significantly reducing the peak impact force, protecting the structural integrity of the components and pipelines, reducing friction and wear, extending the service life of the components and pipelines, adapting to the irregularities of the pipeline inner wall, ensuring operational stability, reducing operating noise and vibration, and improving the working environment.

[0009] Preferably, the scraping mechanism includes a connecting shaft. A second blade is fixedly connected to the outer side of the connecting shaft near the axial flow fan, and an external column is rotatably connected to the outer side of the connecting shaft away from the second blade. A scraping plate is fixedly connected to the outer side of the external column. The axial flow fan generates airflow, which acts on the surface of the second blade. The external column controls the scraping plate to rub against the surface of the grid plate, thereby cleaning impurities from the component surface. This prevents debris from adhering to the component surface and reduces dust adsorption, thus preventing any impact on airflow. Preferably, an outer plate is fixedly connected to the side of the outer post away from the scraper plate. A sliding rod is slidably connected to the outer side of the outer plate. When the spherical block rotates and contacts the holes on the surface of the grid plate, the third spring rebounds, causing the spherical block to collide with the holes in the grid plate, thereby cleaning impurities from the inner wall of the holes. Through a certain range of internal expansion and contraction, the impact on the rotation of the component is reduced while maintaining the cleaning process, thus ensuring continuous operation of the equipment. A spherical block is fixedly connected to the side of the sliding rod near the grid plate. The spherical block is made of silicone material, which serves as a shock absorber and buffer, reducing the vibration amplitude of the component, improving the stability of the component during operation, and reducing wear between components, thereby extending the service life of the component. A third spring is sleeved on the side of the sliding rod near the spherical block. During the rotation of the outer post, the outer plate drives the spherical block to rotate. When the spherical block contacts the surface of the grid plate, the spherical block is subjected to the reaction force of the grid plate, causing the spherical block to drive the sliding rod to compress and contract the third spring, thereby serving as a shock absorber and buffer, and contracting the component to avoid affecting the rotation effect of the component during rotation.

[0010] Preferably, the spraying device includes a spray housing. A water pump is fixedly connected to the top of the spray housing, and the water pump is connected to a water source to send water into the spray housing. The spray housing acts as a water storage tank to ensure continuous supply of water to the components. A connecting pipe is fixedly connected to the outside of the spray housing. The water pump compresses the water flow, causing it to spray out from one side of the nozzle block, thereby achieving the effect of liquid spraying for dust suppression. A nozzle block is fixedly connected to the outside of the connecting pipe on the side away from the spray housing. A ring frame is fixedly connected to the outside of the connecting pipe on the side near the nozzle block. A connecting frame is fixedly connected to the outside of the ring frame. A baffle plate is fixedly connected between the opposite surfaces of the connecting frame. The liquid sprayed from the conical nozzle collides with the baffle plate, thereby breaking the liquid flow, refining the droplets, improving atomization efficiency, significantly improving atomization fineness, and making the spray coverage more uniform. This system improves contact efficiency with the target, changes the spray direction, precisely controls the spray range, reduces spray impact, avoids target damage, stabilizes the spray state, and reduces external interference. The sprayed atomized liquid is blown by the wind force of the pneumatic mechanism, thereby expanding the coverage area of ​​the atomized liquid, increasing the effective area, accelerating droplet diffusion and uniform distribution, avoiding local aggregation, enhancing the contact efficiency between droplets and the target, improving the effect, resisting environmental interference, ensuring the directionality of the atomized liquid, adjusting droplet suspension time, and adapting to different operational needs. A cleaning mechanism is fixedly connected to the inner wall of the nozzle block, and a conical orifice is fixedly connected to the side of the inner wall of the nozzle block near the baffle plate. The conical orifice adopts a conical structure, and according to Bernoulli's principle, by reducing the pipe diameter, the liquid flow velocity is increased, thereby increasing the liquid spray range.

[0011] Preferably, the cleaning mechanism includes a cleaning frame, a connecting shaft rotatably connected to the outer side of the cleaning frame, a third impeller fixedly connected to one side of the connecting shaft, a cleaning bracket fixedly connected to the outer side of the connecting shaft away from the third impeller, and a cleaning plate fixedly connected to the outer side of the cleaning bracket. Water flow impacts the third impeller, causing the connecting shaft to rotate. This allows the cleaning bracket to control the cleaning plate to rub against the inner wall of the conical nozzle, thereby cleaning the nozzle, breaking up fluid adhesion, preventing "liquid film residue" or "airflow stagnation," disturbing the initial flow pattern, assisting atomization or mixing, reducing the adhesion and accumulation of fluid residues, preventing pipe blockage, and preventing impact on subsequent spraying effects.

[0012] This invention provides a dust suppression device for use at construction sites. It has the following beneficial effects: I. The dust suppression equipment used at this construction site utilizes a dust suppression device design. Universal casters support and move the equipment, increasing its range of motion and operational efficiency. A stabilizing mechanism, mounted on the casters, increases the contact area with the ground, enhancing friction and stability, reducing vibration during operation, and improving safety. It also provides cushioning to prevent component swaying from affecting operation. A sliding plate slides inside a rail, causing the dust suppression housing to move up and down, adjusting the equipment height to meet various operational needs. A pneumatic mechanism generates airflow to absorb dust from the construction site, thus achieving dust suppression, protecting human health, reducing disease risks, improving air quality, reducing environmental pollution, and preventing excessive dust from affecting personnel. The dust enters the dust-suppressing base through the pneumatic mechanism. A guide plate inside the base guides the dust, increasing its flow speed and reducing dust residue. The dust is then collected by a collection housing for easy cleaning, ensuring continuous dust collection. A spraying device on top of the housing sprays liquid onto the area, directly wetting the dust and promoting its settling. This forms a physical barrier, preventing dust spread and secondary dust re-entrainment, improving dust suppression efficiency, reducing labor costs, improving the working environment, and ensuring production safety. Furthermore, the pneumatic mechanism alters the airflow direction, adapting to the spraying device. During the liquid spraying process, the wind increases the spray range, further enhancing dust suppression efficiency and expanding the spray area.

[0013] II. The dust suppression equipment used at this construction site employs a stabilizing mechanism design. When the equipment moves to a designated position via the casters, the connecting block drives the telescopic rod to slide within the linear module, bringing the telescopic rod closer to the ground. This increases the contact area between the components and the ground, enhancing friction and thus improving equipment stability. It reduces vibration during operation, improves operational safety, and prevents equipment swaying that could affect performance. When the equipment vibrates, the telescopic rod compresses the first spring, acting as a shock absorber and buffer, mitigating vibration impact and protecting core components. Through elastic deformation or damping, it absorbs and dissipates vibration energy, preventing direct transmission of vibration to core components such as the motor, pipes, nozzles, and control system. This reduces loosening, wear, or breakage caused by long-term vibration, improving equipment stability, ensuring dust suppression effectiveness, reducing noise pollution, improving the working environment, adapting to complex terrain, enhancing equipment applicability, extending equipment lifespan, reducing maintenance costs, and minimizing impact loads. This reduces equipment failure rates and extends service life, thereby reducing repair and replacement costs.

[0014] III. The dust suppression equipment used at the construction site employs a pneumatic mechanism. An axial flow fan rotates to absorb dust from the site. Dust enters the dust suppression base through pneumatic ducts, thus collecting the dust and reducing dust accumulation. A grating plate prevents external impurities from entering the ducts, avoiding blockages and ensuring optimal equipment performance. The wind-driven scraper mechanism rotates, rubbing against the inner wall of the duct to clean away dust, reducing dust buildup and preventing obstruction of subsequent airflow. Residual dust is also addressed. The system collects dust and then uses an axial flow fan to rotate in the opposite direction, causing the airflow to move from the duct to one side of the grating plate. This breaks up localized air stagnation, accelerates dust diffusion or discharge, and, in conjunction with a spraying device, improves the contact efficiency between dust and water mist. When the spraying device sprays liquid to suppress dust on the site, the airflow increases the spraying range, thereby increasing the efficiency of dust suppression and improving the spraying range of the equipment. Additionally, the airflow drives a scraping mechanism to rub against the surface of the grating plate, thus cleaning the dust from the component surface. This prevents debris from adhering to the component surface and reduces dust adsorption, preventing any impact on airflow.

[0015] IV. The dust suppression equipment used at the construction site employs a scraper mechanism design. An axial flow fan generates airflow, which acts on the surface of the first blade. This first blade drives the rotating column to rotate, causing the scraper bracket to control the scraper plates to rub against the inner wall of the pipe. This cleans the inner wall of the pipe, reducing dust adsorption and retention, preventing interference with subsequent airflow, collecting residual dust to prevent pipe blockage, ensuring smooth airflow, preventing secondary dust re-ignition or leakage, reducing pollution risks, protecting downstream equipment, and lowering the probability of failure. During the rotation and friction of the components, vibrations are easily generated. External force causes the connecting rod to compress and contract the second spring, thus acting as a shock absorber and buffer, cushioning impact forces, preventing damage from rigid collisions, absorbing impact energy, and transforming rigid collisions into flexible contact. This significantly reduces the peak impact force, protects the structural integrity of components and pipes, reduces friction and wear, extends the service life of components and pipes, adapts to the irregularities of the inner wall of the pipe, ensures operational stability, reduces operating noise and vibration, and improves the working environment.

[0016] V. The dust suppression equipment used at the construction site employs a scraping mechanism. An axial flow fan generates airflow, which acts on the surface of the second blade. An external column controls the scraping plate to rub against the surface of the grating plate, thus cleaning impurities from the component surface. This prevents debris from adhering to the component surface and reduces dust adsorption, preventing obstruction of airflow. During the rotation of the external column, the external plate drives the spherical block to rotate. When the spherical block contacts the grating plate surface, it experiences a reaction force from the grating plate, causing the spherical block to drive a sliding rod that compresses and contracts the third spring, thus providing shock absorption and cushioning. The retraction of the spherical block during rotation avoids affecting its rotational efficiency. Secondly, when the spherical block contacts the holes on the surface of the grid plate during rotation, the spring rebounds, causing the spherical block to collide with the holes in the grid plate, thereby cleaning impurities from the inner walls of the holes. Through a certain range of internal expansion and contraction, the impact on the rotation of the component is reduced while maintaining the cleaning process, thus ensuring continuous operation of the equipment. The spherical block is made of silicone, which acts as a shock absorber, reducing component vibration, improving the stability of the component during operation, and reducing wear between components, thereby extending the service life of the component.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution: a dust suppression device for construction sites, including a dust suppression device 1, and a spraying device 2 fixedly connected to the top of the dust suppression device 1; The dust suppression device 1 includes a dust suppression housing 11. The top of the dust suppression housing 11 is fixedly connected to the bottom of the spraying device 2. A sliding plate 16 is fixedly connected to the inner side of the dust suppression housing 11. A slide rail 17 is slidably connected to the outer side of the sliding plate 16. A dust suppression base 12 is fixedly connected to one side of the slide rail 17. A universal wheel assembly 14 is fixedly connected to the bottom of the dust suppression base 12. A stabilizing mechanism 15 is fixedly connected to the top edge of the universal wheel assembly 14. A guide plate 13 is fixedly connected to the top of the inner wall of the dust suppression base 12. A collection housing 18 is inserted into the outer side of the dust suppression base 12. A wind-driven mechanism 19 is fixedly connected to the outer side of the dust suppression housing 11. The caster set 14 is used to support and move the equipment, thereby increasing the range of movement and improving operational efficiency. The stabilizing mechanism 15 is mounted on the caster set 14 and contacts the ground, increasing the contact area and friction between the components and the ground, thus improving equipment stability, reducing vibration during operation, and enhancing operational safety. It also provides a buffering effect to prevent component swaying from affecting equipment operation. The sliding plate 16 slides inside the slide rail 17, driving the dust-collecting housing 11 to slide up and down, thereby adjusting the equipment height. The wind-driven mechanism 19 generates wind to absorb dust in the construction site, achieving dust suppression, protecting human health, reducing disease risks, improving air quality, reducing environmental pollution, and preventing excessive dust from affecting personnel. Dust enters the dust-collecting base from the wind-driven mechanism 19. Inside the dust-suppressing base 12, a guide plate 13 is installed to guide the dust, increase the flow speed of dust inside the equipment, and reduce dust residue inside the equipment. The dust is collected by the collection shell 18 to facilitate subsequent cleaning and maintain continuous dust collection. A spraying device 2 is installed on the top of the dust-suppressing shell 11 to spray liquid into the area, thereby achieving the effect of dust suppression. It directly wets the dust, promotes its settling, forms a physical barrier, intercepts the spread of dust, inhibits secondary dust re-entrainment, improves dust suppression efficiency, reduces labor costs, helps improve the working environment, and ensures production safety. Secondly, the airflow direction is changed by the wind-driven mechanism 19 to adapt to the spraying device 2. When the spraying device 2 sprays liquid to suppress dust on the site, the wind force increases the liquid spray range, thereby increasing the efficiency of dust suppression and improving the spray range of the equipment.

[0021] The stabilizing mechanism 15 includes a linear module 151, a connecting block 152 is slidably connected to the inner side of the linear module 151, a telescopic rod 153 is fixedly connected to the outer side of the connecting block 152 away from the linear module 151, and a first spring 154 is sleeved on the outer side of the telescopic rod 153. When the equipment moves to the designated position via the caster wheel assembly 14, the connecting block 152 drives the telescopic rod 153 to slide inside the linear module 151, causing the telescopic rod 153 to contact the ground. This increases the contact area between the components and the ground, improving friction and thus enhancing equipment stability, reducing vibration during operation, and improving operational safety. It also prevents equipment from shaking during operation, which could affect its performance. When the equipment vibrates, the telescopic rod 153 compresses and contracts the first spring 154, acting as a shock absorber and buffer, reducing vibration impact, and protecting core components. Through elastic deformation or damping, it absorbs and dissipates vibration energy, preventing direct transmission of vibration to core components such as the motor, pipes, nozzles, and control system. This reduces loosening, wear, or breakage of components due to long-term vibration, improves equipment stability, ensures dust reduction, reduces noise pollution, improves the working environment, adapts to complex terrain, enhances equipment applicability, extends equipment life, reduces maintenance costs, reduces impact load, lowers equipment failure rate, and extends service life, thereby reducing the cost of repair and replacement parts.

[0022] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 7As shown, the pneumatic mechanism 19 includes a pneumatic frame 191. A pneumatic duct 192 is fixedly connected to one side of the pneumatic frame 191. An axial flow fan 193 is fixedly connected to the inner wall of the pneumatic duct 192 near the pneumatic frame 191. A grid plate 194 is fixedly connected to the inner wall of the pneumatic duct 192 away from the axial flow fan 193. A scraping mechanism 196 is fixedly connected to the outer side of the grid plate 194. A scraper mechanism 195 is fixedly connected to the middle of the inner wall of the pneumatic duct 192. The axial flow fan 193 rotates to absorb dust from the site. The dust enters the dust collection base 12 through the air-driven duct 192, thus collecting the dust and reducing dust in the site. The grating plate 194 blocks external impurities from entering, preventing larger impurities from entering the duct and causing blockages, which would affect the equipment's operating performance. The airflow drives the scraper mechanism 195 to rotate, rubbing against the inner wall of the duct to clean the dust inside, reducing dust adsorption and retention, and preventing it from affecting subsequent airflow. Residual dust is collected, and then the axial flow fan 193... 93 rotates in the opposite direction, causing the airflow from the pneumatic duct 192 to the side of the grating plate 194, thereby breaking the local air stagnation and accelerating the diffusion or discharge of dust. In conjunction with the spraying device 2, it improves the contact efficiency between dust and water mist. When the spraying device 2 sprays liquid to reduce dust on the site, the airflow increases the liquid spraying range, thereby increasing the efficiency of dust reduction on the site and improving the spraying range of the equipment. In addition, the airflow drives the scraping mechanism 196 to rub against the surface of the grating plate 194, thereby cleaning the dust on the surface of the components. On the one hand, it prevents debris from adhering to the surface of the components, and on the other hand, it reduces dust adsorption and prevents it from affecting the gas flow effect.

A rotating column 1953 is rotatably connected to the outside of the receiving shaft 1952. A first blade 1954 is fixedly connected to the outside of the rotating column 1953 away from the grid plate 194. A scraper bracket 1955 is fixedly connected to the outside of the rotating column 1953 away from the first blade 1954. A scraper plate 1956 is fixedly connected to the outside of the scraper bracket 1955. The axial flow fan 193 generates airflow, which acts on the surface of the first blade 1954. The first blade 1954 drives the rotating column 1953 to rotate, causing the scraper bracket 1955 to control the scraper plate 1956 to rub against the inner wall of the pipe, thereby cleaning the inner wall of the pipe, reducing dust adsorption and retention, avoiding affecting the subsequent airflow, collecting residual dust, preventing pipe blockage, ensuring smooth airflow, preventing secondary dust stirring or leakage, reducing the risk of pollution, protecting downstream equipment, and reducing the probability of failure.

[0024] A connecting rod 1957 is fixedly connected between the opposite faces of the scraper bracket 1955, and a second spring 1958 is sleeved on the outer side of the connecting rod 1957. During the rotation and friction of the components, vibrations are easily generated. External force causes the connecting rod 1957 to compress and contract the second spring 1958, thereby playing a role in shock absorption and buffering, buffering impact force, avoiding damage caused by rigid collisions, absorbing impact energy, converting rigid collisions into flexible contact, significantly reducing the peak impact force, protecting the structural integrity of the components and pipelines, reducing friction and wear, extending the service life of the components and pipelines, adapting to the irregularities of the pipeline inner wall, ensuring operational stability, reducing operating noise and vibration, and improving the working environment.

[0025] The scraping mechanism 196 includes a connecting shaft 1961. A second blade 1962 is fixedly connected to the outer side of the connecting shaft 1961 near the axial flow fan 193. An outer post 1963 is rotatably connected to the outer side of the connecting shaft 1961 away from the second blade 1962. A scraping plate 1964 is fixedly connected to the outer side of the outer post 1963. The axial flow fan 193 generates airflow, which acts on the surface of the second blade 1962. The outer post 1963 controls the scraping plate 1964 to rub against the surface of the grid plate 194, thereby cleaning impurities from the component surface. This prevents debris from adhering to the component surface and reduces dust adsorption, thus preventing any impact on airflow.

[0026] An outer plate 1968 is fixedly connected to the outer side of the outer post 1963 away from the scraper plate 1964. A sliding rod 1965 is slidably connected to the outer side of the outer plate 1968. A spherical block 1966 is fixedly connected to the outer side of the sliding rod 1965 near the grid plate 194. A third spring 1967 is sleeved on the outer side of the sliding rod 1965 near the spherical block 1966. During the rotation of the external column 1963, the external plate 1968 drives the spherical block 1966 to rotate. When the spherical block 1966 contacts the surface of the grid plate 194, the spherical block 1966 is subjected to the reaction force of the grid plate 194, causing the spherical block 1966 to drive the sliding rod 1965 to compress and contract the third spring 1967, thereby playing a role in shock absorption and buffering, and shrinking the component to avoid affecting the rotation effect of the component during rotation. Secondly, when the spherical block 1966 contacts the holes on the surface of the grid plate 194 during rotation, the third spring 1967 rebounds, causing the spherical block 1966 to collide with the holes of the grid plate 194, thereby cleaning the impurities on the inner wall of the holes. Through a certain range of internal expansion and contraction, the impact on the rotation of the component is reduced while maintaining the cleaning process, thus ensuring continuous operation of the equipment. The spherical block 1966 is made of silicone material, which plays a role in shock absorption and buffering, reducing the vibration amplitude of the component, improving the stability of the component during operation, and reducing wear between components, thereby extending the service life of the component.

[0027] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9 As shown, the spraying device 2 includes a spraying housing 21. A water pump 22 is fixedly connected to the top of the spraying housing 21. A connecting pipe 23 is fixedly connected to the outside of the spraying housing 21. A nozzle block 24 is fixedly connected to the outside of the connecting pipe 23 away from the spraying housing 21. An annular frame 27 is fixedly connected to the outside of the connecting pipe 23 near the nozzle block 24. A connecting frame 28 is fixedly connected to the outside of the annular frame 27. A baffle plate 29 is fixedly connected between the opposite faces of the connecting frame 28. A cleaning mechanism 25 is fixedly connected to the inner wall of the nozzle block 24. A conical nozzle 26 is fixedly connected to the inner wall of the nozzle block 24 near the baffle plate 29. Water pump 22 connects to a water source and delivers water into the spray housing 21, which acts as a water tank to ensure continuous supply to the components. The water pump 22 compresses the water flow, causing it to spray out from one side of the nozzle block 24, thus achieving the effect of liquid spraying for dust suppression. The conical nozzle 26 adopts a conical structure; based on Bernoulli's principle, by reducing the pipe diameter, the liquid flow velocity is increased, thereby expanding the spray range. The liquid sprayed from the conical nozzle 26 collides with the baffle plate 29, breaking up the liquid flow, refining the droplets, improving atomization efficiency, and significantly enhancing the fineness of the atomization. The spray mechanism allows for more uniform spray coverage, improved contact efficiency with the target, and precise control of the spray range by changing the spray direction. This reduces the impact of the spray, prevents damage to the target, stabilizes the spray state, and minimizes external interference. The sprayed atomized liquid is atomized by the wind force of the pneumatic mechanism 19, thereby expanding the coverage area of ​​the atomized liquid, increasing the effective area, accelerating the diffusion and uniform distribution of droplets, avoiding local aggregation, enhancing the contact efficiency between droplets and the target, improving the effect, resisting environmental interference, ensuring the directionality of the atomized liquid, adjusting the droplet suspension time, and adapting to different operational needs.

[0028] The cleaning mechanism 25 includes a cleaning frame 251, a connecting shaft 253 rotatably connected to the outer side of the cleaning frame 251, a third blade 252 fixedly connected to one side of the connecting shaft 253, and a cleaning bracket 254 fixedly connected to the outer side of the connecting shaft 253 away from the third blade 252. A cleaning plate 255 is fixedly connected to the outer side of the cleaning bracket 254. Water flow impacts the third blade 252, causing the connecting shaft 253 to rotate. This allows the cleaning bracket 254 to control the cleaning plate 255 to rub against the inner wall of the conical nozzle 26, thereby cleaning the nozzle, breaking up fluid adhesion, preventing "liquid film residue" or "airflow stagnation," disturbing the initial flow pattern, assisting atomization or mixing, reducing the adhesion and accumulation of fluid residues, preventing pipe blockage, and preventing impact on subsequent spraying effects.

[0029] In use, the caster set 14 supports and moves the equipment, thereby increasing the range of movement and improving operational efficiency. The stabilizing mechanism 15 is mounted on the caster set 14 and contacts the ground, increasing the contact area and friction between the components and the ground, thus improving equipment stability, reducing vibration during operation, and enhancing operational safety. It also provides a buffering effect to prevent component swaying from affecting equipment operation. The sliding plate 16 slides inside the slide rail 17, driving the dust-collecting housing 11 to slide up and down, thereby adjusting the equipment height. The wind-driven mechanism 19 generates wind to absorb dust in the construction site, achieving dust suppression, protecting human health, reducing disease risks, improving air quality, reducing environmental pollution, and preventing excessive dust from affecting personnel. Dust enters the dust-collecting housing through the wind-driven mechanism 19. Inside the base 12, a guide plate 13 is installed to guide the dust, increase the flow speed of dust inside the equipment, and reduce dust residue. The dust is collected by the collection shell 18 for easy subsequent cleaning, ensuring continuous dust collection. A spraying device 2 is installed on the top of the dust-suppressing shell 11 to spray liquid onto the site, thereby achieving the effect of dust suppression. It directly wets the dust, promotes its settling, forms a physical barrier, intercepts dust diffusion, inhibits secondary dust re-entrainment, improves dust suppression efficiency, reduces labor costs, helps improve the working environment, and ensures production safety. Secondly, the airflow direction is changed by the wind-driven mechanism 19, which is adapted to the spraying device 2. When the spraying device 2 sprays liquid onto the site for dust suppression, the wind force increases the liquid spray range, thereby increasing the efficiency of dust suppression and expanding the spray range of the equipment.
