Description

TECHNICAL FIELD

[0001] The present application relates to the field of dust suppression technology, in particular to a spray dust suppression and dust adsorption device integrated with a construction fence. BACKGROUND

[0002] In the process of urban construction and reconstruction, a large amount of construction dust is inevitably generated in activities such as building engineering and road construction. These dusts are not only one of the main sources of inhalable particulate matter (such as PM10, PM2.5), which seriously pollutes the atmospheric environment, but also pose a threat to the health of on-site construction personnel and surrounding residents, and affect the normal operation of mechanical equipment. Therefore, effective control of construction dust has become a core requirement of green construction and civilized construction site management.

[0003] At present, the common dust suppression measures at construction sites mainly include two categories: one is an active spray dust suppression system, and the other is a passive dust adsorption facility. The active spray dust suppression system usually uses a fixed pipe network and spray head installed around or inside the construction area to generate water mist by water pump pressure to capture and settle dust in the air. The passive adsorption facility refers to the installation of dust prevention nets, dust suppression cloth or adsorption cotton and other materials on the construction fence, which rely on their physical properties to block and adsorb part of the dust.

[0004] However, the above existing technologies have obvious limitations in practical application. The passive dust prevention net, dust suppression cloth and other facilities have very limited dust suppression effect. They can only block some larger particle dust, and have insufficient adsorption capacity for fine dust. Moreover, they are easily saturated and damaged by wind and sun, and need to be replaced frequently, which has high maintenance cost and cannot achieve effective and continuous dust control. Secondly, the fixed spray dust suppression system needs to lay complex pipelines and water supply lines, which has large installation foundation engineering quantity and high cost. Construction activities often have the characteristics of stages and intermittence, and are not continuous. During the non-construction period, the whole system is idle, causing a huge waste of resources. More troublesome is that after the project is completed, this system customized for a specific construction site loses its place in the sun, and the process of disassembly, transportation and reinstallation is extremely cumbersome, with poor economic efficiency. Moreover, the disassembled parts are doubtful in their adaptability to another construction site, and most of them end up as waste products, which does not conform to the economic concept of green recycling. SUMMARY

[0005] In order to improve the problems existing in the above-mentioned technology, the present application provides a spray dust suppression and dust adsorption device integrated with a construction fence.

[0006] The spray dust suppression and dust adsorption device integrated with a construction fence provided by the present application adopts the following technical solution: The application discloses a spray dust and dust adsorption device integrated with a construction fence, which comprises a mounting seat, a spraying mechanism and an adsorption mechanism are arranged on the mounting seat, and a connecting mechanism for detachable connection with the construction fence is arranged on the mounting seat.

[0007] By adopting the technical scheme, the spraying mechanism and the adsorption mechanism are integrated into a compact functional module through the mounting seat as a unified bearing platform, and the module can be conveniently fixed on the construction fence through the connecting mechanism for detachable connection, thereby forming a dynamic dust-settling system working in cooperation. In actual work, when dust is generated during construction activities, the spraying mechanism is started to spray water mist into the air to actively capture and settle dust particles, thereby forming the first efficient defense line. Meanwhile, dust that is not completely captured by the water mist or escapes during the intermittent period of the water mist is secondarily intercepted by the adjacent adsorption mechanism through physical adsorption, thereby forming the passive and continuous second defense line. The physical integration realized by the mounting seat ensures that the two mechanisms closely cooperate in space, and the functions of active spraying and passive adsorption are complementary and synergistic. The detachable connecting mechanism is the key to realizing the migration of the device, and enables the entire functional module to be quickly detached from the old fence after the completion of a single project and reused on the fence of a new construction site without damage. Through the adoption of the technical scheme, the structures can cooperate in space and function, which not only significantly improves the dust-settling efficiency and the processing capacity for fine dust, but also fundamentally solves the inherent contradictions of the traditional fixed system, such as complex installation, difficult migration and single effect of passive facilities, and realizes the unity of dust-settling effect, economy and resource recycling.

[0008] Optionally, the connecting mechanism comprises a clamping seat in sliding connection with the mounting seat, and a driving assembly is arranged on the mounting seat and used for driving the clamping seat to slide in the direction away from or close to the mounting seat.

[0009] Through the adoption of the technical scheme, when the device needs to be installed on the rail or frame of the construction fence, the driving assembly is operated to drive the clamping seat to slide in the direction close to the mounting seat, so that the fence plate is stably pressed between the clamping seat and the mounting seat to form a strong clamping force, thereby ensuring the stability of the device in the wind and rain or vibration environment; when the project is completed and needs to be disassembled, the driving assembly is reversely operated to drive the clamping seat to slide in the direction away from the mounting seat, so that the clamping force is quickly released, one-key quick disassembly is realized, and the operation is convenient.

[0010] Optionally, a first arc groove is formed on the side, opposite to the mounting seat, of the clamping seat, a second arc groove is formed on the clamping seat and opposite to the first arc groove, a first plane side is arranged below the first arc groove of the mounting seat, and a second plane side is arranged on the clamping seat and opposite to the first plane side.

[0011] By adopting the technical scheme, the cooperation of the first arc groove and the second arc groove and the cooperation of the first plane side and the second plane side enable the cooperation of the clamping seat and the mounting seat to form a "contour self-adaptive clamping" for common profiles (square tubes and round tubes) of construction fences, thereby realizing the unity of universality, stability and protection. During work, when the device needs to be installed on a common round rail, the driving assembly drives the clamping seat to approach the mounting seat, the round tube is accommodated in a circular or approximately circular space formed by the first arc groove and the second arc groove, the arc surface is attached to the tube wall, efficient force transmission and extremely high torsional stability are realized; when the device needs to be installed on a square column or frame, the clamping seat is also driven to slide by the driving assembly, at this time, the first plane side and the second plane side will be parallel to the two sides of the square tube, providing the maximum contact area and stable support. The cooperation of the components in the above process enables the device to automatically adapt to different shapes of support members of the construction site fence without the need to replace any parts, avoids damage to the coating or structure of the fence caused by local stress concentration due to point contact or line contact, and ensures the most reliable connection stiffness in various cases through surface contact and arc surface contact, thereby improving the applicability and installation reliability of the device as a standardized module on different construction sites and different specifications of fences.

[0012] Optionally, the mounting seat bottom is provided with a telescopic support rod, the telescopic support rod bottom is provided with a threaded rod, the threaded rod bottom is conical, and a connecting sleeve is threadedly connected on the threaded rod, and the connecting sleeve is provided with a connecting portion for connecting with the ground.

[0013] By adopting the technical scheme, the "telescopic supporting rod", the "pointed threaded rod" at the bottom and the "connecting sleeve" are matched to form a dual-mode auxiliary supporting system which can adapt to soft and hard ground. During the working process, when the device needs to be installed in a soft soil site, the pointed bottom end of the threaded rod is exposed, the pointed bottom of the threaded rod breaks the ground, and the threaded rod is rotated into the deep soil like a pile. At this time, the threaded rod serves as the main bearing component and provides stable anchoring through its large surface friction. When the site is a hard surface such as cement or asphalt, the threaded rod does not need to be rotated into the ground, the connecting sleeve is rotated to hide the pointed bottom end of the threaded rod inside, the connecting sleeve is tightly pressed on the ground, and the connecting sleeve and the ground are connected through the connecting part. At this time, the connecting surface at the bottom of the connecting sleeve provides stability through large static friction, and the threaded rod mainly plays a role in transferring pressure and adjusting height. The cooperation of the components in the above process enables the device as a whole to achieve "deep foundation anchoring" on soft ground and "large-area compression" on hard surfaces through different operation modes without any part replacement, thereby ensuring that the dust falling device can obtain reliable auxiliary support on most typical construction sites, greatly improving the universality and environmental adaptability of the device.

[0014] Optionally, a matching seat is rotatably connected to the mounting seat, and the spraying mechanism and the adsorption mechanism are arranged on the matching seat; a telescopic drive rod is arranged on the mounting seat, and a spherical hinge seat is slidably connected to the mounting seat, and the movable end of the telescopic drive rod is connected to the spherical hinge seat.

[0015] By adopting the technical scheme, the "spraying mechanism" and the "adsorption mechanism" are arranged on a rotatable "matching seat", and the "spherical hinge connection" between the "telescopic drive rod" and the matching seat is used for driving, thereby constructing a universal adjusting mechanism which can flexibly and accurately adjust the spraying and adsorption directions. During the working process, when it is necessary to target specific dust sources (such as earthwork points or vehicle entrances) or adapt to wind direction changes, the telescopic drive rod performs telescopic movement; the top end of the telescopic drive rod applies a direction-variable pushing force or pulling force to the matching seat through the spherical hinge seat, and the spherical hinge seat adaptively slides in this process. Since the matching seat and the mounting seat are rotatably connected, the force is converted into torque to drive the entire matching seat together with the spraying mechanism and the adsorption mechanism thereon to pitch or deflect by a certain angle in the horizontal and vertical directions. This dynamic cooperation relationship enables the spraying jet and the adsorption area to no longer be fixed in one direction, but can be tracked and directionally covered in real time as a whole functional unit according to the actual situation of dust diffusion, thereby greatly improving the efficiency and range of dust capture, overcoming the problem of coverage dead angle of traditional fixed nozzles, realizing the leap from "passive static dust falling" to "active dynamic tracking dust falling", and significantly enhancing the dust suppression effect of the device in complex and variable construction environments.

[0016] Optionally, the adsorption mechanism is arranged below the spraying mechanism, and a flow guide plate is arranged between the adsorption mechanism and the spraying mechanism, and the flow guide plate is raised upward away from the side of the mounting base.

[0017] By adopting the above technical scheme, in the working process, the spraying mechanism sprays water mist upward to capture dust, at this time, the obliquely arranged flow guide plate plays multiple synergistic effects: firstly, it can intercept large-diameter water droplets that have not completely evaporated or settled and fall downward, avoiding being sucked by the adsorption mechanism below, thereby avoiding problems such as saturation, blockage, efficiency reduction, and even damage of the dust removal fan caused by the adsorption of too much water mist, prolonging the service life of the adsorption mechanism and reducing the maintenance frequency; secondly, the arrangement of the flow guide plate indirectly ensures that the water mist sprayed by the spraying mechanism has enough time and space to capture and settle dust, avoiding the waste caused by the water mist being sucked by the adsorption mechanism in advance before fully exerting its effect. The synergistic cooperation composed of "space difference" and "physical guidance" enables the adsorption mechanism to focus on adsorption, and the water resource utilization rate of the spraying mechanism is maximized, thereby significantly improving the dust reduction economy and operation reliability of the device as a whole.

[0018] Optionally, an air compressor is arranged on the mounting base, and an air outlet is formed in the mounting base and communicates with a jet port of the air compressor, and the air outlet is located on the side of the flow guide plate away from the adsorption mechanism.

[0019] By adopting the above technical scheme, by additionally arranging an air compressor on the side of the flow guide plate away from the adsorption mechanism, an invisible "air curtain wall" is formed by the high-speed airflow sprayed from the air outlet, realizing flexible isolation of water mist and automatic cleaning of the surface of the flow guide plate, achieving the intelligent effects of double protection and self-maintenance. In the working process, the dry and clean airflow generated by the air compressor is shot out from the air outlet, forming a stable air curtain barrier between the spraying area and the adsorption mechanism; this air curtain can effectively isolate the diffused water mist from the air inlet of the adsorption mechanism, because of its physical properties, it only blocks small water droplets but allows larger dust particles to pass through, thereby greatly improving the reliability of preventing water mist from being sucked in without interfering with the dust reduction effect; at the same time, this continuous airflow flows closely to the surface of the flow guide plate, can continuously blow off a small amount of water droplets or dust that may be attached to the flow guide plate, preventing them from accumulating to form stains or falling, realizing passive and continuous online cleaning of the flow guide plate, ensuring the long-term flow guiding efficiency of the flow guide plate and the cleanliness of the device. This "harmonious" cooperative defense system composed of rigid flow guide plates and flexible air curtains not only fundamentally eliminates the interference of water mist, but also endows the device with the ability of self-maintenance, significantly reducing the cost of manual cleaning and improving the stability and durability of the equipment in long-term unattended working conditions.

[0020] Optionally, the mounting seat is provided with a suction port, the suction mechanism comprises a filter screen arranged at the suction port, and the suction port is communicated with a suction pipe used for being connected with an air inlet of a dust removal fan; the mounting seat is provided with a communication port, the air outlet and the suction port are communicated with the communication port, and a partition plate used for closing the communication port is detachably connected to the mounting seat.

[0021] By adopting the above technical scheme, when the device is operated, the communication port is closed by the partition plate, the air compressor and the dust removal fan are independently operated, the air compressor forms an air curtain barrier between the spraying area and the suction mechanism, the suction pipe is connected with the dust removal fan, the dust removal fan is operated to suck the dust through the filter screen into the suction port, and the filter screen is used to protect the internal space of the suction port and the dust removal fan, so that larger garbage and sundries are prevented from entering the suction port.

[0022] The filter screen may be partially or completely blocked during long-term operation of the device, at this time, the partition plate can be detached, and the gas blown out of the air outlet can blow the filter screen surface and the deflector plate at the same time and in the same direction, so as to realize efficient cleaning. The design of integrating the maintenance entrances of two independent systems into a single window avoids the complex structure of opening multiple maintenance entrances at different positions of the device, significantly simplifies the maintenance process, realizes "one-stop" convenient maintenance of the core components, and improves the maintainability and user experience of the device.

[0023] Optionally, the partition plate can be bent, the mounting seat is provided with a slot, the slot is communicated with the communication port, when the partition plate is inserted into the slot, the partition plate closes the communication port, the slot is provided with a first magnetic block, the partition plate is provided with a second magnetic block, the first magnetic block and the second magnetic block are magnetically attracted and can be attached to each other.

[0024] By adopting the above technical scheme, through cooperation of the "bendable partition plate" and the "slot with magnetic adsorption", the sealing performance and stability of the partition plate in the closed state are greatly improved while realizing the convenient opening and maintenance function, and the problems of air tightness decline and vibration abnormal sound caused by assembly gap are effectively solved. During the working process, when maintenance is performed, the operator only needs to overcome the magnetic force to pull out the partition plate from the slot, and the bendable characteristic facilitates operation and storage in a narrow space; when the communication port needs to be closed after maintenance, the partition plate is inserted into the slot through the gas outlet and the communication port in sequence, and in the last stage of the insertion process, the second magnetic block arranged on the partition plate and the first magnetic block in the slot are automatically aligned and tightly adsorbed under the action of the magnetic force, not only providing a clear "hand feeling", but also eliminating the slight shaking gap caused by the slightly larger diameter of the slot through the strong magnetic adsorption force, so that the partition plate is tightly fitted with the mounting seat. The composite fixing mode of "rigid insertion" and "flexible magnetic adsorption" not only guarantees the mechanical strength of the partition plate bearing the internal gas pressure, but also compensates for the tolerance by using the magnetic force, realizes self-centering and self-locking, thereby ensuring the air tightness of the airflow channel of the device during operation, avoiding noise and additional energy loss caused by vibration of the partition plate, and improving the overall reliability and user experience of the equipment.

[0025] Optionally, a positioning block is arranged on the guide plate, two positioning grooves for inserting the positioning block are arranged on the partition plate, and the partition plate has a closed position and a shielding position. When the partition plate is in the closed position, the partition plate is inserted into the slot to the deepest position, the first magnetic block and the second magnetic block are in close contact with each other, the positioning block is located in one of the positioning grooves, and the end of the partition plate extends into the gas outlet but does not completely block the gas outlet. When the partition plate moves outward from the closed position to the shielding position, the first magnetic block and the second magnetic block are separated, the positioning block is located in the other positioning groove, and the second magnetic block partially or completely shields the gas outlet. A third magnetic block is arranged on the positioning block, and a fourth magnetic block is arranged in the positioning groove, and the third magnetic block and the fourth magnetic block are magnetically attracted.

[0026] By adopting the above technical solution, a mechanical positioning system consisting of a "positioning block" and two "positioning slots," working in conjunction with a magnetic fixing system, provides clear, stable, and reliable tactile and auditory feedback for the two core working positions of the partition: "closed" and "blocked." This ensures the accuracy of functional state switching and the stability of device operation. During operation, when the partition needs to be pushed to the closed position, the operator pushes the partition inward along the slot. Upon reaching the end of the stroke, the first and second magnetic blocks engage to provide fixing force. Since the partition can be bent, it can be manipulated to allow the positioning block to engage in the first positioning slot. The fourth magnetic block in the slot engages with the third magnetic block on the positioning block, providing strong lateral auxiliary positioning and reinforcement, effectively preventing the partition from slipping under equipment vibration. When switching to the shielding position to adjust the air curtain, slightly bend the partition to disengage the positioning block from the first positioning slot, pull out the partition, and separate the first and second magnetic blocks. After that, insert the positioning block into the second positioning slot, where the fourth magnetic block in the slot attracts the third magnetic block on the positioning block. The second magnetic block is now located at the air outlet. In the length direction perpendicular to the air outlet, the cross-section of the second magnetic block is larger than the cross-section of the partition. Therefore, when the second magnetic block is located at the air outlet, it can partially or completely block the air outlet. This state is suitable when the device needs maintenance, the connection port needs to be opened but the air outlet needs to be temporarily closed (e.g., to prevent foreign objects from entering or to concentrate the airflow from the air jet towards the filter). The second magnetic block can act as a temporary cover at the air outlet position.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a "mounting base" as a unified support platform, the "spraying mechanism" and "adsorption mechanism" are integrated into a compact functional module. A "detachable connection mechanism" allows this module to be easily fixed to the construction fence, thus forming a collaborative and dynamic dust suppression system. During actual operation, when construction activities generate dust, the spraying mechanism activates, spraying water mist into the air to actively capture and settle dust particles, forming the first efficient line of defense. Simultaneously, dust particles not completely captured by the water mist or released during the mist's intervals are physically trapped by the adjacent adsorption mechanism, forming a passive and continuous second line of defense. This physical integration achieved by the mounting base ensures close spatial coordination between the two mechanisms, realizing the complementary and synergistic effects of "active spraying" and "passive adsorption." The detachable connection mechanism is key to the device's portability, allowing the entire functional module to be quickly removed from the old fence after a single project and reinstalled without damage on the fence of a new construction site for reuse. By adopting the above technical solutions, the various structures can work together in terms of space and function, which not only significantly improves the dust reduction efficiency and the ability to handle fine dust, but also fundamentally solves the inherent contradictions of traditional fixed systems being complex to install and difficult to relocate, and passive facilities having limited effects, thus achieving a unity of dust reduction effect, economy and resource recycling.

[0030] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0031] Example 1 Embodiment 1 of this application discloses a spray dust suppression and dust adsorption device integrated into a construction fence. (Refer to...) Figures 1-6 The integrated dust suppression and dust adsorption device for construction fences includes a mounting base 1, a spraying mechanism 2 and an adsorption mechanism 3 on the mounting base 1, and a connection mechanism 5 for detachable connection with the construction fence 4 on the mounting base 1.

[0032] Mounting base 1, as the core load-bearing component, is typically made of metal or high-strength engineering plastic, providing a mounting foundation for other functional components. The spraying mechanism 2 and the adsorption mechanism 3 are both integrated onto mounting base 1. Connecting mechanism 5, located on mounting base 1, is used to detachably secure the entire device to construction fencing 4 (such as common railings or frames).

[0033] When construction activities generate dust, the spray mechanism 2 activates, spraying water mist into the air to actively capture and settle dust particles, forming the first line of defense. Simultaneously, dust particles not completely captured by the water mist or released during the mist's intervals are then physically trapped by the adjacent adsorption mechanism 3, forming a passive and continuous second line of defense. This physical integration, achieved through the mounting base 1, ensures close spatial coordination between the two mechanisms, realizing functional complementarity and synergistic effect between "active spraying" and "passive adsorption." The detachable connection mechanism 5 is key to the device's portability, allowing the entire functional module to be quickly removed from the old fence after a single project is completed and reinstalled without damage on the fence of a new construction site for reuse.

[0034] Reference Figures 1-6 The connecting mechanism 5 includes a clamping seat 501 slidably connected to the mounting base 1. The mounting base 1 is also provided with a driving assembly 502, such as an electric push rod, cylinder, or manual screw drive mechanism, for driving the clamping seat 501 to slide in a direction away from or towards the mounting base 1 body. To accommodate fence components with different cross-sectional shapes (such as round or square tubes), a first arc groove 6 is formed on the side of the mounting base 1 opposite to the clamping seat 501, and a corresponding second arc groove 7 is formed on the clamping seat 501. Flexible sealing gaskets are provided on the opposite sides of both the first arc groove 6 and the second arc groove 7. When clamping a round tube, the first arc groove 6 and the second arc groove 7 together form an approximately circular clamping structure. Meanwhile, the mounting base 1 is provided with a first planar side 8 below the first arc groove 6, and the clamping base 501 is provided with a second planar side 9 opposite to the first planar side 8. Flexible sealing gaskets are provided on the opposite side of the first planar side 8 and the second planar side 9. When clamping a square tube or a rectangular beam, the first planar side 8 and the second planar side 9 can press the two side planes of the component in parallel.

[0035] Reference Figures 1-6 In Embodiment 1 of this application, the driving component 502 is selected as a first electric push rod 5021. The first electric push rod 5021 is horizontally arranged, and its fixed end is fixedly connected to the mounting base 1. Its movable end is fixedly connected to the clamping base 501. Multiple T-shaped sliders (not shown in the figure) are integrally formed on the clamping base 501. The multiple T-shaped sliders are spaced apart along a sliding direction perpendicular to the clamping base 501. The mounting base 1 has multiple grooves 32 parallel to the sliding direction of the clamping base 501. Each T-shaped slider is located in a groove 32, and each T-shaped slider slides in accordance with its corresponding groove 32. The extension and retraction of the movable end of the first electric push rod 5021 can drive the clamping base 501 to slide, thereby allowing the T-shaped sliders to slide in their corresponding grooves 32. The cooperation between the multiple T-shaped sliders and the grooves 32 improves the stability of the clamping base 501 during the sliding process.

[0036] ReferenceFigures 1-6 The mounting base 1 has a telescopic support rod 10 at its bottom, and a threaded rod 11 at its bottom. The bottom of the threaded rod 11 is conical. A connecting sleeve 12 is threaded onto the threaded rod 11. The connecting sleeve 12 has a connecting part for connecting with the ground 43. The connecting part is selected as multiple connecting plates 13 that are spaced apart around the circumference of the connecting sleeve 12. Each connecting plate 13 has a threaded hole.

[0037] When the device needs to be installed on a soft soil surface, the pointed bottom end of the threaded rod 11 is exposed. The pointed bottom end of the threaded rod 11 breaks through the ground 43, and it is screwed deep into the soil like a ground pile. At this time, the threaded rod 11, as the main load-bearing component, provides a stable anchoring through its huge surface friction. When the site is a hard surface such as cement or asphalt, it is not necessary to screw the threaded rod 11 into the ground 43. Rotate the connecting sleeve 12 so that the pointed bottom end of the threaded rod 11 is hidden inside the connecting sleeve 12, so that the connecting sleeve 12 is tightly pressed onto the ground 43. The connecting plate 13 establishes a connection between the connecting sleeve 12 and the ground 43. At this time, the connecting surface at the bottom of the connecting plate 13 provides stability through huge static friction. The threaded rod 11 mainly plays the role of transmitting pressure and adjusting height. When it is necessary to further improve the stability of the device when it is located on a hard ground 43, the connecting plate 13 can be anchored to the ground 43 through the threaded hole, thereby establishing a stable connection between the device and the ground 43.

[0038] Reference Figures 1-6 In Embodiment 1 of this application, the telescopic support rod 10 includes a fixed rod 1001, a movable rod 1002, and a positioning pin 1003. Both the fixed rod 1001 and the movable rod 1002 are vertically arranged and are coaxially slidably connected. The fixed rod 1001 has a mating cavity for the movable rod 1002 to slide inside. The fixed rod 1001 has a plurality of first positioning holes 34 spaced apart along its length, and the movable rod 1002 has a plurality of second positioning holes 35 spaced apart along its length. When it is necessary to adjust the overall length of the telescopic support rod 10, the movable rod 1002 is slid to change the length of the movable rod 1002 exposed above the fixed rod 1001. When the movable rod 1002 slides to the desired position, the positioning pin 1003 is simultaneously inserted through any set of aligned first positioning holes 34 and second positioning holes 35, thereby completing the fixation of the movable rod 1002.

[0039] In other embodiments, the telescopic support rod 10 may be an electric push rod with a power source, a cylinder, or a screw drive mechanism, thereby reducing manual operation costs.

[0040] Reference Figures 1-6A mounting base 1 is rotatably connected to a mating base 14, on which both the spray mechanism 2 and the adsorption mechanism 3 are mounted. A dust removal fan 36 and a water tank 38 are located at the bottom of the mating base 14. An air duct 37 connects to the air inlet of the dust removal fan 36, and an outlet pipe 39 connects to the water outlet of the water tank 38. A water pump is installed inside the water tank 38, and its outlet is connected to the outlet pipe 39. An adsorption port 20 is provided inside the mating base 14. The adsorption mechanism 3 includes a filter screen 301 detachably connected to the adsorption port 20. An adsorption pipe 302 connects to the adsorption port 20 and is used to connect to the air duct 37. When the dust removal fan 36 operates, dust can pass sequentially through the filter screen 301, the adsorption port 20, and the adsorption pipe 302 until it enters the chamber of the dust removal fan 36. The spraying mechanism 2 includes a support base 201 mounted on a mating base 14. A water spray pipe 202 is mounted on the support base 201. A nozzle 203 is inclinedly mounted on the top end of the water spray pipe 202. The bottom end of the water spray pipe 202 passes through the support base 201 and can be connected to the outlet pipe 39 of the water storage tank 38. When the water pump in the water storage tank 38 is operating, the water in the water storage tank 38 can enter the nozzle 203 in sequence through the outlet pipe 39 and the water spray pipe 202. The nozzle 203 operates to atomize and spray the water.

[0041] Reference Figures 1-6 The mating seat 14 has an installation cavity 21, and an electrically controlled telescopic drive rod 15 is horizontally arranged in the installation cavity 21. The fixed end of the telescopic drive rod 15 is fixedly connected to the installation cavity 21. The mating seat 14 has a guide groove (not shown in the figure) on the side away from the nozzle 203. The guide groove is vertically arranged in a direction perpendicular to the telescopic drive rod 15. A guide block (not shown in the figure) is slidably connected in the guide groove. A ball joint seat 16 is arranged on the guide block. The ball joint seat 16 is connected to the movable end of the telescopic drive rod 15.

[0042] When it is necessary to target specific dust sources (such as earthwork operation sites, vehicle entrances and exits) or adapt to changes in wind direction, the telescopic drive rod 15 extends and retracts. The top of the telescopic drive rod 15 applies a variable-direction thrust or pull force to the mating seat 14 through the ball joint seat 16. During this process, the ball joint seat 16 slides adaptively. Since the mating seat 14 and the mounting seat 1 are rotatably connected, this force is converted into torque, driving the entire mating seat 14 together with the spray mechanism 2 and the adsorption mechanism 3 on it to pitch or deflect at a certain angle in the horizontal and vertical directions.

[0043] In Embodiment 1 of this application, in order to further improve the stability of the ball joint seat 16 during the sliding process, the sliding direction and range of the ball joint seat 16 on the mating seat 14 are limited by the cooperation of the guide groove and the guide block, so as to prevent the ball joint seat 16 from disengaging from the mating seat 14 during the sliding process, and at the same time facilitate the telescopic movement of the telescopic drive rod 15.

[0044] Reference Figures 1-6A guide plate 17 is provided on the mounting base 14. The guide plate 17 is located between the nozzle 203 and the suction port 20, and the side of the guide plate 17 away from the mounting base 14 is raised upward. An air compressor 18 is installed inside the mounting base 14. An air outlet 19 is opened on the mounting base 14 and communicates with the air jet of the air compressor 18. The air outlet 19 is located between the guide plate 17 and the nozzle 203. A connecting port 23 is opened on the mounting base 14, and both the air outlet 19 and the suction port 20 communicate with the connecting port 23. A partition 24 for sealing the connecting port 23 is detachably connected to the mounting base 1.

[0045] During operation, the spray mechanism 2 sprays water mist upwards to capture dust. The inclined guide plate 17 intercepts large-diameter water droplets that fail to evaporate or settle and drip downwards, preventing them from being directly sucked away by the adsorption port 20. It also indirectly ensures that the water mist sprayed through the nozzle 203 has sufficient time and space to capture and settle dust, avoiding waste caused by the adsorption mechanism 3 prematurely sucking away the water mist before it has fully exerted its effect. By adding an air compressor 18 to the side of the guide plate 17 away from the adsorption port 20, an invisible "air curtain" is formed by the high-speed airflow from the air outlet 19, achieving flexible isolation of the water mist and automatic cleaning of the guide plate 17 surface, thus achieving a dual protection and self-maintenance intelligent effect. When the device is in operation, the connecting port 23 is closed by the partition 24. The air compressor 18 and the dust removal fan 36 operate independently. The air compressor forms an air curtain barrier between the spray area and the adsorption mechanism 3. The adsorption pipe 302 is connected to the external dust removal fan 36. The dust removal fan 36 operates to adsorb dust through the filter screen 301 into the adsorption port 20. The filter screen 301 is used to protect the internal space of the adsorption port 20 and the dust removal fan 36 to prevent large garbage and debris from accidentally entering it.

[0046] Reference Figures 1-6 The partition 24 can be bent. The mounting base 1 has a slot 25, which is connected to the connecting port 23. When the partition 24 is inserted into the slot 25, the partition 24 closes the connecting port 23. The slot 25 is embedded with a first magnetic block 26, and a second magnetic block 27 is fixed on the partition 24. The first magnetic block 26 and the second magnetic block 27 are magnetically attracted to each other and can stick together.

[0047] Reference Figure 7The guide plate 17 is provided with a positioning block 28, and the partition plate 24 is provided with two positioning slots 29 for the positioning block 28 to be inserted. The partition plate 24 has a closed station and a blocking station. When the partition plate 24 is in the closed station, it is inserted into the slot 25 to the deepest position, the first magnetic block 26 and the second magnetic block 27 are in contact with each other, the positioning block 28 is located in one of the positioning slots 29, and the end of the partition plate 24 extends into the air outlet 19 but does not completely block the air outlet 19. When the partition plate 24 moves outward from the closed station to the blocking station, the first magnetic block 26 and the second magnetic block 27 separate, the positioning block 28 is located in the other positioning slot 29, and the second magnetic block 27 partially blocks the air outlet 19. A third magnetic block 30 is embedded in the positioning block 28, and a fourth magnetic block 31 is embedded in the positioning slot 29. The third magnetic block 30 and the fourth magnetic block 31 are magnetically attracted to each other.

[0048] In Embodiment 1 of this application, the partition 24 is made of a flexible board with a soft material, which has high flexibility and can be bent at any position.

[0049] During operation, when the partition 24 needs to be pushed to the closed workstation, the operator pushes the partition 24 inward along the slot 25. When it reaches the end of the stroke, the first and second magnetic blocks 27 attract each other to provide fixing force. Since the partition 24 can be bent, the partition 24 can be operated at this time so that the positioning block 28 is inserted into the first positioning slot 29. The fourth magnetic block 31 in the slot attracts each other with the third magnetic block 30 on the positioning block 28, providing strong auxiliary positioning and reinforcement from the side, effectively preventing the partition 24 from slipping under equipment vibration. When it is necessary to switch to the shielding position to adjust the air curtain, slightly bend the partition 24 so that the positioning block 28 disengages from the first positioning slot 29, pull out the partition 24, and separate the first magnetic block 26 and the second magnetic block 27. After that, insert the positioning block 28 into the second positioning slot 29. The fourth magnetic block 31 in the slot and the third magnetic block 30 on the positioning block 28 attract each other. The second magnetic block 27 is located at the air outlet 19. In the length direction perpendicular to the air outlet 19, the cross-section of the second magnetic block 27 is larger than the cross-section of the partition 24. Therefore, when the second magnetic block 27 is located at the air outlet 19, the second magnetic block 27 can partially shield the air outlet 19. This state is suitable when the device needs to be maintained, the communication port 23 needs to be opened, but the air outlet 19 needs to be temporarily closed (for example, to prevent foreign objects from entering or to make the airflow from the air jet more concentrated towards the filter screen 301). The second magnetic block 27 can act as a temporary cover at the air outlet 19.

[0050] The implementation principle of the spray dust suppression and dust adsorption device integrated into the construction fence in Embodiment 1 of this application is as follows: First, the device is quickly installed in a suitable position on the construction fence 4 through the connecting mechanism 5. The length and fixing method of the telescopic support rod 10 are adjusted according to the ground conditions 43. Power and water supply are connected. When dust is generated during construction, the spray mechanism 2 is activated to spray water mist to capture dust particles in the air. At the same time, the angle of the mating seat 14 can be adjusted by controlling the telescopic drive rod 15 according to the location and wind direction of the dust source, so that the spray and adsorption directions are aligned with the dust diffusion path. For fine dust not captured by the spray or during the water mist interval, the fan of the adsorption mechanism 3 is activated to draw air through the adsorption port 20, and the filter screen 301 traps the dust. The air compressor continuously forms an air curtain between the spray area and the adsorption area to prevent water mist from affecting the adsorption mechanism 3. The guide plate 17 intercepts larger water droplets falling. During regular maintenance, the partition 24 can be moved to a shielded position or completely removed to clean or replace the filter 301. Alternatively, the airflow from the air compressor can be used to backflush the filter 301. After the project is completed, the device can be easily disassembled and transported to a new construction site for reuse.

[0051] Example 2 The difference between Example 2 and Example 1 is that: (Refer to...) Figure 8 and ​ The partition 24 is made of a plate with high strength and hardness. The partition 24 includes a first plate 40 and a second plate 41 that are hinged to each other. The second magnet 27 is fixed to one end of the first plate 40. A hinge shaft 42 is provided at the end of the first plate 40 away from the second magnet 27. One end of the second plate 41 is sleeved on the hinge shaft 42 and rotates with the hinge shaft 42.

[0052] The implementation principle of Example 2 is as follows: the partition 24 has high strength and hardness, thereby improving the stability of the partition 24 when closing the connecting port 23.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
