Description

Technical Field

[0001] This invention relates to the field of outdoor special building technology, and in particular to a road protection structure for highway construction. Background Technology

[0002] Premixed mortar is widely used in current road construction, and many projects set up premixed mortar tanks on-site. However, the use of dry-mixed mortar easily generates dust, necessitating the installation of dedicated dust suppression sheds. Currently, most construction sites arrange mortar tanks in an open manner, or only use simple protective measures such as fine-mesh netting and formwork. These practices not only have limited dust control effectiveness and fail to effectively protect the health of construction workers, but also result in a messy appearance, lack of uniform standards, and inability to be disassembled and reused. They are neither aesthetically pleasing nor in line with the principles of green and standardized construction. Summary of the Invention

[0003] The purpose of this invention is to provide a road protection structure for highway construction, which can seal mortar tanks and use spraying to suppress dust, thereby improving the dust prevention effect.

[0004] To achieve the above objectives, the present invention provides a road protection structure for highway construction, including a support assembly, a top cover, and a spray dust suppression assembly. The support assembly includes a support body, two rotating cover plates, a locking structure, and a surrounding plate. The two rotating cover plates are rotatably disposed on one side of the support body. The locking structure is fixed on the rotating cover plates to lock the rotating cover plates after they are closed. The surrounding plate is disposed on the support body. The top cover includes a lifting frame, an inclined cover plate, and an auxiliary baffle. The lifting frame is slidably disposed on the top of the support body, the inclined cover plate is fixed on the top of the lifting frame, and the auxiliary baffle plate is fixed on one side of the lifting frame. The dust suppression spray assembly includes an annular spray pipe, multiple atomizing nozzles, an angle adjustment structure, and a water supply structure. The annular spray pipe is disposed on one side of the support body, and the multiple atomizing nozzles are connected to the annular spray pipe. The angle adjustment structure is disposed on one side of the annular spray pipe and is used to adjust the angle of the atomizing nozzles. The water supply structure is connected to the annular spray pipe.

[0005] The support assembly also includes a sealing strip, which is disposed on one side of the rotating cover plate.

[0006] The locking structure includes a locking rod, a locking groove, and an elastic element. The locking rod is slidably disposed on one of the rotating cover plates, the locking groove is fixed on another rotating cover plate, and the elastic element is used to support the locking rod.

[0007] The bracket body is equipped with an outer steel plate and an inner dustproof mesh plate, and a sound insulation cavity is provided between the outer steel plate and the inner dustproof mesh plate.

[0008] The top cover also includes a negative pressure fan and a cartridge dust collector. The negative pressure fan is fixed below the inclined cover plate, and the cartridge dust collector is connected to the negative pressure fan and located below the inclined cover plate.

[0009] The top cover also includes a trapezoidal tube, a filter, and a storage box. The trapezoidal tube is located on one side of the inclined cover plate and is used to collect rainwater. The filter is fixed below the trapezoidal tube, and the storage box is connected to the filter and the annular spray pipe.

[0010] The filter includes a filter screen, a filter element, and a cleaner. The filter screen is fixed above the trapezoidal tube, the filter element is fixed below the trapezoidal tube, and the cleaner is slidably disposed on the filter screen.

[0011] The cleaner includes a slider, a screw, a motor, and a cleaning brush. The slider is slidably disposed on one side of the filter screen, the screw is threadedly connected to the slider, the output end of the motor is fixedly connected to the screw, and the cleaning brush is disposed on the slider.

[0012] The cleaner also includes a gear and a rack. The gear is fixed to the cleaning brush, and the rack is fixed to one side of the trapezoidal tube and meshes with the gear.

[0013] The tilt adjustment structure includes multiple rotating blocks, multiple push rods, an adjusting ring, and an adjusting cylinder. The multiple rotating blocks are rotatably arranged around the annular spray pipe. The adjusting ring is slidably arranged above the multiple rotating blocks. One end of the multiple push rods is rotatably connected to the multiple rotating blocks, and the other end of the multiple push rods is rotatably connected to the adjusting ring. The output end of the adjusting cylinder is connected to the adjusting ring.

[0014] This invention discloses a road protection structure for highway construction. The support body is made of high-strength metal material, possessing good stability and load-bearing capacity, and can be securely installed at the edge of the construction area or on both sides of temporary passages. Two rotating cover plates are symmetrically arranged on one side of the support body and can be flexibly opened and closed through a hinge mechanism, facilitating the entry and exit of construction personnel or the passage of equipment. When the cover plates are closed, a locking structure on them can securely lock them, preventing accidental opening due to wind, vibration, or human error, thereby ensuring the continuity and safety of protection. Enclosure plates are fixed around the outer perimeter or inner side of the support body, which not only enhances the overall structural rigidity but also provides initial protection against dust, flying gravel, and noise transmission.

[0015] The top cover, positioned above the support components, primarily serves to shield against falling objects, rain, and direct sunlight, while also optimizing airflow to aid dust suppression. The top cover comprises a lifting frame, an inclined cover plate, and auxiliary baffles. The lifting frame is slidably mounted on top of the support structure via slide rails or guide columns, allowing for vertical adjustment to suit different working conditions. The inclined cover plate is fixedly installed at the top of the lifting frame, its surface designed with a slight inclination to facilitate rapid rainwater drainage and reduce dust accumulation; simultaneously, the inclination angle guides airflow upwards, reducing localized dust concentration. The auxiliary baffles are fixed vertically or slightly inclined to one side of the lifting frame to further prevent dust carried by lateral winds from escaping to public roads or the surrounding environment, thus improving environmental performance.

[0016] A ring-shaped spray pipe is arranged around one side of the support body, forming a closed or semi-closed spray barrier. Multiple high-precision atomizing nozzles are evenly distributed and connected to the ring-shaped spray pipe, capable of atomizing water into micron-sized droplets, efficiently adsorbing and settling dust particles in the air. To adapt to different wind directions, construction heights, and dust source locations, this invention features a tilt adjustment structure, allowing real-time or preset adjustment of the spray angle of the atomizing nozzles to ensure precise spray coverage and maximize dust suppression effect. The water supply structure is reliably connected to the ring-shaped spray pipe, and can be connected to a municipal water supply system or a self-supplied water source, supporting continuous or intermittent spraying operations. Optional water filtration and pressure stabilization devices are also available to ensure long-term stable system operation.

[0017] The road protection structure provided by this invention not only has excellent physical protection capabilities, but also integrates intelligent and adjustable spray dust suppression functions, which significantly improves the working environment at highway construction sites, effectively reduces the impact on surrounding traffic and residents, and meets the development requirements of modern green construction and civilized construction.

[0027] Please see Figures 1-5This invention provides a road protection structure for highway construction, including a support assembly, a top cover, and a dust suppression spray assembly. The support assembly includes a support body 101, two rotating cover plates 102, a locking structure 103, and a surrounding plate 104. The two rotating cover plates 102 are rotatably disposed on one side of the support body 101. The locking structure 103 is fixed to the rotating cover plates 102 to lock the closed rotating cover plates 102. The surrounding plate 104 is disposed on the support body 101. The top cover includes a lifting frame 105, an inclined cover plate 106, and an auxiliary baffle 107. The lifting frame 105 is slidably disposed on the top cover. The inclined cover plate 106 is fixed to the top of the lifting frame 105 at the top of the support body 101, and the auxiliary baffle 107 is fixed to one side of the lifting frame 105. The spray dust suppression assembly includes an annular spray pipe 108, multiple atomizing nozzles 109, an angle adjustment structure 110, and a water supply structure. The annular spray pipe 108 is disposed on one side of the support body 101, and the multiple atomizing nozzles 109 are connected to the annular spray pipe 108. The angle adjustment structure 110 is disposed on one side of the annular spray pipe 108 and is used to adjust the angle of the atomizing nozzles 109. The water supply structure is connected to the annular spray pipe 108.

[0028] In this embodiment, the support body 101 is made of high-strength metal material, possessing good stability and load-bearing capacity, and can be securely installed at the edge of the construction area or on both sides of temporary passages. Two rotating cover plates 102 are symmetrically arranged on one side of the support body 101, and can be flexibly opened and closed through a hinge mechanism, facilitating the entry and exit of construction personnel or the passage of equipment; when the cover plate is closed, the locking structure 103 (such as a buckle, pin, or electromagnetic lock) provided on it can securely lock it, preventing accidental opening due to wind, vibration, or human error, thereby ensuring the continuity of protection and safety. The surrounding plate 104 is fixed around the outer perimeter or inner side of the support body 101, which not only enhances the overall structural rigidity, but also plays a role in initially blocking dust, flying gravel, and noise transmission.

[0029] The top cover, positioned above the support components, primarily serves to shield against falling objects, rain, and direct sunlight, while also optimizing airflow to aid dust suppression. The top cover comprises a lifting frame 105, an inclined cover plate 106, and an auxiliary baffle 107. The lifting frame 105 is slidably mounted on the top of the support body 101 via a slide rail or guide column structure, allowing for vertical adjustment to suit different working conditions. The inclined cover plate 106 is fixedly installed at the top of the lifting frame 105, its surface designed with a slight inclination to facilitate rapid rainwater drainage and reduce dust accumulation; simultaneously, the inclination angle guides airflow upwards, reducing local dust concentration. The auxiliary baffle 107 is vertically or slightly inclinedly fixed to one side of the lifting frame 105 (usually facing the interior of the construction area) to further prevent dust carried by crosswinds from escaping to public roads or the surrounding environment, thus improving environmental performance.

[0030] An annular spray pipe 108 is arranged around one side of the support body 101 (usually located on the inner side near the construction surface), forming a closed or semi-closed spray barrier. Multiple high-precision atomizing nozzles 109 are evenly distributed and connected to the annular spray pipe 108, capable of atomizing water into micron-sized droplets, efficiently adsorbing and settling dust particles in the air. To adapt to different wind directions, construction heights, and dust source locations, this invention features a tilt adjustment structure 110 (such as a rotary joint, electric push rod 133, or manual adjustment knob), which allows for real-time or preset adjustment of the spray angle of the atomizing nozzles 109, ensuring precise spray coverage and maximizing dust suppression effect. The water supply structure (including a water pump, water pipeline, and water tank) is reliably connected to the annular spray pipe 108, and can be connected to a municipal water supply system or a self-supplied water source, supporting continuous or intermittent spraying operations. Optional water filtration and pressure stabilization devices are also available to ensure long-term stable system operation.

[0031] The road protection structure provided by this invention not only has excellent physical protection capabilities, but also integrates intelligent and adjustable spray dust suppression functions, which significantly improves the working environment at highway construction sites, effectively reduces the impact on surrounding traffic and residents, and meets the development requirements of modern green construction and civilized construction.

[0032] The support assembly also includes a sealing strip 112, which is disposed on one side of the rotating cover plate 102.

[0033] The support assembly also includes a sealing strip 112, which is preferably made of a weather-resistant elastic material (such as EPDM rubber or silicone) and has excellent anti-aging, UV resistance, and high and low temperature resistance. The sealing strip 112 is fixedly installed circumferentially on one or both rotating cover plates 102 on one side of the mating edge. When the two rotating cover plates 102 are closed, the sealing strip 112 fits tightly against the corresponding contact surface of the other cover plate or the support body 101, effectively filling the gaps and preventing dust, fine particles, or moisture generated during construction from leaking out from the cover plate joints, thereby significantly enhancing the overall airtightness and environmental isolation effect of the protective structure.

[0034] The locking structure 103 includes a locking rod 113, a locking groove 114, and an elastic element 115. The locking rod 113 is slidably disposed on one of the rotating cover plates 102, the locking groove 114 is fixed on another rotating cover plate 102, and the elastic element 115 is used to support the locking rod 113.

[0035] The locking rod 113 is slidably mounted at the end of a rotating cover plate 102 via a sliding guide mechanism (such as a groove or guide rail); the locking groove 114 is correspondingly and fixedly installed at the mating position of another rotating cover plate 102, and its interior has a locking cavity that matches the shape of the end of the locking rod 113. When the two cover plates are closed in place, the operator pushes or pulls the locking rod 113 to insert it into the locking groove 114, thereby achieving mechanical interlocking. To ensure the stability of the locked state and the automatic reset function, the elastic element 115 (such as a compression spring or torsion spring) is disposed between the locking rod 113 and the cover plate. On the one hand, it provides a preload force to the locking rod 113, so that it remains locked in the locked position without external force, preventing loosening due to vibration or wind load; on the other hand, it provides a rebound assist when unlocking, facilitating quick opening. This locking structure 103 is easy to operate, highly reliable, and requires no external energy, making it suitable for various field construction environments.

[0036] The bracket body 101 is equipped with an outer steel plate 116 and an inner dustproof mesh plate 117, and a sound insulation cavity is provided between the outer steel plate 116 and the inner dustproof mesh plate 117.

[0037] The support body 101 adopts a composite sandwich structure design: an outer steel plate 116 is installed on the side facing the construction area. This steel plate is made of high-strength cold-rolled steel or galvanized steel plate, possessing good impact resistance, corrosion resistance, and structural support performance. An inner dustproof mesh plate 117 is installed on the side facing the public road or surrounding environment. This mesh plate is typically composed of stainless steel wire mesh, perforated aluminum plate, or polymer composite filter screen, with optimized pore size design to effectively intercept larger dust particles while ensuring ventilation. Crucially, a closed or semi-closed soundproof cavity is formed between the outer steel plate 116 and the inner dustproof mesh plate 117. This cavity not only acts as a physical sound barrier, using an air layer to block the sound wave propagation path and significantly reduce the outward diffusion of noise generated by construction machinery operation and crushing operations, but can also be filled with sound-absorbing cotton, porous foam, or damping materials as needed to further enhance the noise reduction effect.

[0038] The top cover also includes a negative pressure fan 118 and a cartridge dust collector 119. The negative pressure fan 118 is fixed below the inclined cover plate 106, and the cartridge dust collector 119 is connected to the negative pressure fan 118 and located below the inclined cover plate 106.

[0039] The top cover also includes a negative pressure fan 118 and a cartridge dust collector 119. The negative pressure fan 118 is fixedly installed below the inclined cover plate 106, preferably located on the side closer to the construction area, with its air inlet facing the work surface and its outlet connected to the cartridge dust collector 119 via a duct. During operation, after the negative pressure fan 118 starts, it creates a local negative pressure zone inside the protective structure, actively drawing in dust, suspended particulate matter, and harmful gases generated during construction, effectively preventing dust from spilling onto public roads or the surrounding environment. The dust-laden airflow is then guided into the cartridge dust collector 119 for efficient purification. The cartridge dust collector 119 uses high-precision membrane filter cartridges as the core filtration element, achieving a capture efficiency of over 99% for fine particles such as PM10 and PM2.5. The purified clean air can be directly discharged or recycled. The entire dust removal system is compact, energy-efficient, and easy to maintain, significantly improving the air quality at the construction site and meeting the dual requirements of green construction and occupational health protection.

[0040] The top cover also includes a trapezoidal tube 120, a filter 121, and a storage box 122. The trapezoidal tube 120 is disposed on one side of the inclined cover plate 106 for collecting rainwater. The filter 121 is fixed below the trapezoidal tube 120. The storage box 122 is connected to the filter 121 and the annular spray pipe 108.

[0041] The trapezoidal pipe 120 is installed along the edge or slope of the inclined cover plate 106. Its trapezoidal cross-section provides a large water collection area and excellent flow guidance, efficiently collecting rainwater falling on the inclined cover plate 106 during rainfall and guiding it into the treatment unit below. The filter 121 is fixedly installed below the outlet end of the trapezoidal pipe 120 to perform preliminary purification of the collected rainwater, removing leaves, silt, oil, and other impurities to ensure the water quality meets subsequent usage requirements. The treated rainwater is temporarily stored in a storage tank 122, which is connected to the filter 121 and the annular spray pipe 108 in the aforementioned dust suppression spray assembly via pipes. This allows the recycled rainwater to be used as a supplementary water source for the spray system, achieving a closed-loop cycle of "rainwater-filtration-storage-reuse," significantly reducing dependence on municipal water supply or external water sources, lowering construction water costs, and embodying the concepts of eco-friendliness and resource conservation.

[0042] The filter 121 includes a filter screen 123, a filter element 124, and a cleaner 125. The filter screen 123 is fixed above the trapezoidal tube 120, the filter element 124 is fixed below the trapezoidal tube 120, and the cleaner 125 is slidably disposed on the filter screen 123.

[0043] The filter screen 123, made of stainless steel wire mesh or porous polymer material, is fixedly installed above the inlet of the trapezoidal tube 120. It primarily intercepts large particles of debris (such as leaves, plastic fragments, and insects) to prevent them from entering subsequent pipes and causing blockages. The filter element 124 is installed at the lower outlet of the trapezoidal tube 120 and is typically made of activated carbon, quartz sand, or multi-layered fiber filter media. It adsorbs fine suspended solids, organic pollutants, and some heavy metal ions, improving water cleanliness. To address the problem of the filter screen 123 easily becoming clogged with debris after long-term use, this invention includes a cleaner 125. This cleaner 125 is slidably mounted on the surface of the filter screen 123 via a slide rail or guide rod. It can be manually pulled periodically or equipped with a small motor 128 for automatic reciprocating motion. The cleaner 125 has scraper or brush structures that effectively remove dirt adhering to the filter screen 123 during sliding and guide it to a sludge collection tank or drain outlet, thereby maintaining the long-term efficient operation of the filtration system and reducing maintenance frequency and manual intervention.

[0044] The cleaner 125 includes a slider 126, a screw 127, a motor 128, and a cleaning brush 129. The slider 126 is slidably disposed on one side of the filter screen 123. The screw 127 is threadedly connected to the slider 126. The output end of the motor 128 is fixedly connected to the screw 127. The cleaning brush 129 is disposed on the slider 126.

[0045] The slider 126 is made of wear-resistant engineering plastic or lightweight aluminum alloy. Its main structure is slidably mounted on a guide rail or bracket on one side of the filter screen 123, allowing it to move smoothly back and forth along the length of the filter screen 123. The screw 127 is arranged horizontally and forms a precision lead screw pair with the threaded hole inside the slider 126, realizing efficient conversion from rotary motion to linear motion. The motor 128 (preferably a waterproof DC geared motor 128 or a stepper motor 128) is fixedly installed on the end of the trapezoidal tube 120 or on the top cover support structure. Its output shaft is fixed to one end of the screw 127 through a coupling or direct rigid connection. When the motor 128 starts, it drives the screw 127 to rotate, thereby driving the slider 126 to slide at a uniform speed along the surface of the filter screen 123. The cleaning brush 129 is fixedly installed on the side of the slider 126 facing the filter screen 123. The brush bristles are made of corrosion-resistant and highly elastic nylon or polypropylene material, which closely adheres to the surface of the filter screen 123. During the movement of the slider 126, the brush scrapes and sweeps the screen surface, effectively removing attached leaves, mud, fibers and other debris, ensuring that the filter channel is unobstructed.

[0046] The cleaner 125 also includes a gear 130 and a rack 131. The gear 130 is fixed on the cleaning brush 129, and the rack 131 is fixed on one side of the trapezoidal tube 120 and meshes with the gear 130.

[0047] The gear 130 is coaxially fixed to the rotating shaft or brush holder of the cleaning brush 129 and can move with the cleaning brush 129 as a whole. The rack 131 is firmly installed on the inner wall of one side of the trapezoidal tube 120 or on a special bracket along the extension direction of the filter screen 123, and its teeth precisely mesh with the gear 130. When the slider 126 moves under the drive of the screw 127, the cleaning brush 129 moves forward synchronously, and the gear 130 rolls along the rack 131. This not only guides and limits the cleaning brush 129, but also constrains its movement within a plane strictly parallel to the filter screen 123, preventing tilting or lifting and ensuring that the bristles always make uniform contact with the screen surface. In addition, this gear 130-rack 131 structure can also convert part of the driving force into a slight rotation or vibration of the cleaning brush 129, enhancing its ability to remove stubborn stains and further improving the cleaning effect.

[0048] It is worth mentioning that the entire cleaner 125 can be automatically started and stopped by the control system at preset time intervals (such as after each rainfall, daily timer, or based on feedback from the differential pressure sensor), and also supports remote manual control to achieve intelligent operation and maintenance. The motor 128, gear 130, and electrical interfaces are all equipped with waterproof sealing structures, making them suitable for harsh outdoor construction environments with heavy rain, high humidity, and dust.

[0049] The tilt adjustment structure 110 includes multiple rotating blocks 132, multiple push rods 133, an adjusting ring 134, and an adjusting cylinder 135. The multiple rotating blocks 132 are rotatably arranged around the annular spray pipe 108. The adjusting ring 134 is slidably arranged above the multiple rotating blocks 132. One end of the multiple push rods 133 is rotatably connected to the multiple rotating blocks 132, and the other end of the multiple push rods is rotatably connected to the adjusting ring 134. The output end of the adjusting cylinder 135 is connected to the adjusting ring 134.

[0050] Multiple rotating blocks 132 are evenly distributed circumferentially and rotatably mounted on the outer periphery of the annular spray pipe 108. Each rotating block 132 is hinged to the annular spray pipe 108 via a pin or bearing, and its upper end is provided with a mounting seat for fixing the atomizing nozzle 109. When the rotating block 132 rotates around its hinge axis, it can drive the connected atomizing nozzle 109 to synchronously change its pitch angle, thereby adjusting the spray direction.

[0051] Above the multiple rotating blocks 132, an integral adjusting ring 134 is provided. This adjusting ring 134 is circular and coaxially sleeved around the annular spray pipe 108. It is axially sliding via vertical guide rails, grooves, or guide columns, allowing it to rise and fall smoothly in the vertical direction, but it cannot rotate. Multiple push rods 133 are arranged corresponding to each rotating block 132. One end of each push rod 133 is rotatably connected to the upper part of the corresponding rotating block 132 via a ball joint or pin, and the other end is connected to the lower edge of the adjusting ring 134 via a rotating pair. Thus, the push rods 133 structurally constitute a multi-link mechanism: when the adjusting ring 134 moves up and down, the pushing and pulling action of the push rods 133 converts the linear motion into the rotational motion of each rotating block 132, thereby synchronously driving all atomizing nozzles 109 to achieve a consistent tilt angle change.

[0052] To drive the movement of the adjusting ring 134, this invention employs an adjusting cylinder 135 as the actuating element. The adjusting cylinder 135 is vertically mounted on the support frame of the bracket body 101 or the annular spray pipe 108, and its piston rod (i.e., the output end) is rigidly connected to the top or side wall of the adjusting ring 134. When compressed air is introduced into the cylinder, the piston rod extends or retracts, pushing the adjusting ring 134 to rise and fall axially. This, in turn, links all rotating blocks 132 via the push rod 133, achieving overall and synchronous adjustment of the spray angle of all atomizing nozzles 109. For example, when the adjusting cylinder 135 extends, the adjusting ring 134 moves downward, and the push rod 133 pushes the rotating block 132 to flip outward, causing the nozzle to tilt downward, suitable for near-field ground dust suppression. Conversely, when the cylinder retracts, the adjusting ring 134 moves upward, and the push rod 133 pulls the rotating block 132 inward, causing the nozzle to tend towards horizontal or even slightly upward tilt, which can be used to intercept dust from high places or form an aerial water curtain barrier.

[0053] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
