Description

Technical Field

[0001] This invention relates to the field of dust suppression equipment technology, specifically to an environmentally friendly dust suppression spray device for highway construction. Background Technology

[0002] Highway construction projects are large-scale and long-term, and the construction process will have various impacts on the surrounding environment. In general, these impacts include the following: (1) damage to the ecological environment; (2) pollution of the water environment; and (3) pollution of the atmospheric environment. Among them, the pollution of the atmospheric environment includes exhaust gas emitted by construction machinery and equipment and transport vehicles burning fuel, as well as a large amount of dust generated during construction processes such as earthwork excavation, material stockpiling, and sand and gravel loading and unloading. Under the action of wind, dust will spread into the surrounding air, reduce air quality, and affect the lives and health of surrounding residents. Especially in dry and windy seasons, the dust problem is more serious. In order to ensure effective control of construction environmental pollution, highway construction units will use dust suppression spray equipment and distribute it in sections with large construction dust to control the dust environmental problems generated during construction.

[0003] However, the environmentally friendly dust suppression spraying devices commonly used by construction companies are transported by small vehicles and then sprayed to suppress dust along the road sections they pass through. This technical solution has certain shortcomings because most sections of highway construction areas are unpaved dirt roads. In dry seasons, there is a lot of floating dust on the ground. Most existing dust suppression spraying devices only spray dust in the air, but do not treat the dust on the ground. As a result, when transport vehicles pass by, the floating dust on the ground is carried back into the air, thus failing to effectively solve the dust problem. Therefore, an environmentally friendly dust suppression spraying device for highway construction is proposed. Summary of the Invention

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The embodiments of the present invention will now be described.

[0046] An environmentally friendly dust suppression spraying device for highway construction, such as Figures 1 to 14 As shown, it includes a drive track 100, a spraying assembly 200 mounted on one side of the drive track 100, a support assembly 300 mounted on the top of the spraying assembly 200, a dust suppression assembly 400 connected to the top of the support assembly 300, a drive assembly 500 installed inside the dust suppression assembly 400, a power supply assembly 600 connected to the input end of the drive assembly 500 via a wire, a trigger assembly 700 installed inside the spraying assembly 200, and a transmission assembly 800 mounted on the top of the trigger assembly 700.

[0047] There are two sets of drive tracks 100, which are symmetrically distributed on both sides of the spraying assembly 200. The input end of the drive track 100 is electrically connected to the power supply assembly 600 through a wire.

[0048] During highway construction, workers operate the device to move it to the section requiring dust suppression. Then, the power supply unit 600 controls two sets of drive tracks 100 to move the spraying unit 200. The movement of the spraying unit 200 moves the support unit 300, which in turn moves the dust suppression unit 400. Workers control the power supply unit 600 to supply power to the drive unit 500 and the dust suppression unit 400. The dust suppression unit 400 sprays water mist, and the drive unit 500 disperses the water mist into the surrounding air through wind power, adsorbing dust in the surrounding air and causing it to fall to the ground, thus achieving initial dust suppression in the area. Workers continue to operate the drive tracks 100 to move slowly, thereby achieving dust suppression along the route. At the same time, the spraying unit 200 sprays water twice on the ground along the route, and the triggering unit 700 and the transmission unit 800 automatically increase the spraying effect in areas with potholes along the route.

[0049] Please refer to this carefully. Figures 3 to 6 The spraying assembly 200 includes a water tank 210 connected to one side of the drive track 100. A cover plate 220 is connected to the top of the water tank 210. A front guide plate 230 is fitted onto the inner wall of the water tank 210. A rear guide plate 240 is fixed to one end of the inner wall of the water tank 210 at the front guide plate 230. A front spray bar 250 communicating with the water tank 210 is fitted to one end of the water tank 210, and a rear spray bar 260 communicating with the water tank 210 is installed at the other end of the water tank 210. The front spray bar 250 includes a front guide pipe 251 communicating with one end of the inner wall of the water tank 210. A first tilting plate 252 is installed at the input end of the front guide pipe 251, and a front nozzle 253 is fitted to the output end of the front guide pipe 251. The front guide plate 230... The first flip plate 252 is rotatably connected to the front guide pipe 251 via a torsion spring. The first flip plate 252 is initially tilted. The tilt angle of the front guide plate 230 is smaller than the tilt angle of the first flip plate 252. The rear spray bar 260 includes a rear guide pipe 261 that communicates with the other end of the inner wall of the water tank 210. The input end of the rear guide pipe 261 is equipped with a second flip plate 262, and the output end of the rear guide pipe 261 is equipped with a rear nozzle 263. The rear guide plate 240 is tilted. The second flip plate 262 is rotatably connected to the rear guide pipe 261 via a torsion spring. The second flip plate 262 is initially tilted. The tilt angle of the rear guide plate 240 is smaller than the tilt angle of the second flip plate 262.

[0050] In highway construction sections, most of the unpaved roads will be riddled with potholes by construction vehicles. Since they are dirt roads, there will inevitably be uphill and downhill sections. On these potholes or sloping surfaces, the dust is usually thicker.

[0051] Based on the above, when the driving device passes through these potholes or sloping sections of road, the overall balance of the device is disrupted, and it begins to bounce up and down during the journey. The bouncing of the device causes the water tank 210 to bounce, which in turn causes the solution inside to sway. The solution sways back and forth along its forward direction and generates a surge phenomenon. When the solution moves forward, some of the solution moves along the extension direction of the front guide plate 230. When this solution moves to contact the first tilting plate 252, the moving solution pushes the first tilting plate 252 to move, thereby causing the first tilting plate 252 to rotate counterclockwise. After the first tilting plate 252 rotates counterclockwise, the inlet of the front guide pipe 251 increases. In addition, the solution rushes into the interior of the front guide pipe 251 under the action of inertia. Due to the increase in the inlet and the impact of the water flow inertia, the spray volume of the front nozzle 253 increases.

[0052] Meanwhile, when the solution moves to the inner wall of the front end of the water storage tank 210, the solution is blocked and moves backward, thereby guiding the solution through the rear guide plate 240, which causes the second flip plate 262 to rotate clockwise. The clockwise rotation of the second flip plate 262 causes the opening of the rear guide pipe 261 to increase, thereby increasing the spray volume of the rear nozzle 263.

[0053] The aforementioned structure utilizes the device's forward and backward movement during transport to focus on spraying potholes and sloping sections of the ground via the spraying component 200. This allows for adaptive dust suppression on surfaces with heavy dust accumulation, reducing the need for frequent operator intervention to control the spray volume and increasing the device's fault tolerance.

[0054] Please refer to this carefully. Figures 10 to 14The triggering component 700 includes a limiting ring 710 connected to the inner wall of the spraying component 200. A connecting shaft 720 is fitted to one end of the limiting ring 710. A sleeve 730 is installed on the outer wall of the connecting shaft 720. A swing plate 740 is connected to the bottom end of the sleeve 730. A connecting pipe 750 is provided on the outer wall of the sleeve 730. A driven plate 760 is installed at the top end of the connecting pipe 750. The transmission component 800 includes an arc-shaped connecting plate 810 connected to the outer wall of the driven plate 760. A first rotating shaft 820 is fitted to the end of the arc-shaped connecting plate 810 away from the driven plate 760. A guide plate 830 is provided to the end of the first rotating shaft 820 away from the arc-shaped connecting plate 810. A second rotating shaft 840 is fixedly connected to the top of the guide plate 830. A limit plate 850 is installed at the top of the second rotating shaft 840. A ball shaft 860 is assembled inside the limit plate 850. A hydraulic component 870 is fixedly connected to the outer wall of the ball shaft 860. A metal bellows 880 is provided at the output end of the hydraulic component 870. A guide ring 890 is installed inside the metal bellows 880. The bottom end of the guide ring 890 is fixedly connected to the top of the spraying assembly 200 through a support block. The second rotating shaft 840 is rotatably connected to the inner wall of the spraying assembly 200 through a limit hole. The limit plate 850 is rotatably connected to the ball shaft 860. The hydraulic component 870 is connected to the metal bellows 880.

[0055] When the device passes through potholes and sloping sections, although the spraying component 200 has a good effect on suppressing ground dust, the ground sprayed by the front spraying strip 250 will still carry a certain amount of dust, and this amount of dust is greater than that of flat sections. This means that when the dust suppression component 400 uses the normal spraying amount to suppress dust in the surrounding environment, it cannot achieve the ideal dust suppression effect.

[0056] Based on the above, the swaying of the solution inside the water tank 210 is also used to drive the swing plate 740 to move in the direction of the water flow. The movement of the swing plate 740 drives the sleeve 730 to rotate, thereby driving the connecting pipe 750 to rotate. The movement of the connecting pipe 750 drives the driven plate 760 to make a fan-shaped motion. The driven plate 760 and the swing plate 740 always present an angle of 180 degrees.

[0057] The movement of the driven plate 760 causes the arc-shaped connecting plate 810 to move, thereby causing the first rotating shaft 820 to rotate and generate displacement. The movement of the first rotating shaft 820 causes the guide plate 830 to move, thereby causing the second rotating shaft 840 to rotate. The rotation of the second rotating shaft 840 causes the limiting plate 850 to perform an arc-shaped movement, thereby causing the ball shaft 860 to move. The movement of the ball shaft 860 compresses the input end of the hydraulic component 870, thereby causing the hydraulic component 870 to inject liquid into the metal bellows 880. After receiving the liquid, the metal bellows 880 extends along the extension direction of the guide ring 890. Due to the metal bellows 880 The extended end is connected to the sliding block 380 in the support assembly 300 (described later in the text), and the sliding block 380 has a guide groove inside that matches the guide ring 890, so that the metal bellows 880 moves along the guide ring 890 with the sliding block 380. The movement of the sliding block 380 drives the support assembly 300 to move as a whole, thereby causing the dust suppression assembly 400 and the drive assembly 500 to swing (the swing angle needs to be less than 60 degrees to prevent interference with the support block at the bottom of the guide ring 890), increasing the area of ​​water mist spraying, thereby increasing the dust suppression spraying effect on this section of road.

[0058] In some embodiments of the present invention, to further enhance the dust suppression effect on bumpy and sloping road sections, two sets of sensing sensors can be installed on the outer wall of the metal corrugated pipe 880. When the metal corrugated pipe 880 is injected with liquid, its length changes, and the wrinkled part of the outer wall of the metal corrugated pipe 880 begins to separate. When the two sets of sensing sensors detect the separation of the wrinkles on the outer wall of the metal corrugated pipe 880, they transmit an electrical signal to the power supply component 600. After receiving the electrical signal, the power supply component 600 controls the dust suppression component 400 to increase the spray volume, thereby further reducing dust on bumpy and sloping road sections. The main features are that both the dust suppression range and the dust suppression amount are improved.

[0059] Please refer to this carefully. Figures 10 to 13 The support assembly 300 includes an arc-shaped limiting ring 310 fixedly connected to the top of the spraying assembly 200. An upper limit plate 320 is mounted on the top of the arc-shaped limiting ring 310. A sliding block 380 is connected to the bottom of the upper limit plate 320 on one side of the arc-shaped limiting ring 310. A vertical plate 330 is installed on the top of the upper limit plate 320. A horizontal plate 340 is provided on one side of the vertical plate 330. A support column 370 is mounted on the bottom of the horizontal plate 340. A limiting roller 350 is rotatably connected to the top of the vertical plate 330 via a bearing (the limiting roller 350 includes a threaded rod and a snap-fit ​​rod rotatably connected to one end of the threaded rod. The vertical plate 330 has a threaded hole inside that matches the threaded rod). A rotating disk 360 is fixedly connected to one end of the limiting roller 350. A limiting slot is opened at the other end of the limiting roller 350.

[0060] When the sliding block 380 moves along the guide ring 890, it drives the upper limit plate 320 to move, which in turn drives the vertical plate 330 to move. The movement of the vertical plate 330 drives the limit roller 350 to move, and the movement of the limit roller 350 drives the dust suppression component 400 to swing.

[0061] Please refer to this carefully. Figure 3 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The dust suppression assembly 400 includes a restraining ring 410 connected to the support assembly 300. One end of the restraining ring 410 is provided with an air inlet 420. A snap-fit ​​ring 430 is installed at the end of the air inlet 420 away from the restraining ring 410. A protective cover 440 is fitted at the end of the snap-fit ​​ring 430 away from the air inlet 420. An air inlet 450 penetrating to the inner wall of the protective cover 440 is opened on the outer wall of the protective cover 440. The air inlets 450 are equidistantly distributed on the outer wall of the protective cover 440. The other end of the restraining ring 410 is provided with an exhaust pipe 460. A drainage hole 470 penetrating to the inner wall of the exhaust pipe 460 is opened on the outer wall of the exhaust pipe 460. A spray element 480 is installed at the end of the exhaust pipe 460 away from the restraining ring 410. The air inlet 450 is opened along the central axis of the protective cover 440, and the drainage hole 470 is opened along the central axis of the exhaust pipe 460. The central axis of the protective cover 440 and the central axis of the air inlet 450 are the same central axis. The spray component 480 includes a guide ring 481 connected to the outer wall of the exhaust pipe 460. A water inlet pipe 482 is fitted at the bottom end of the guide ring 481. A flow divider 483 is installed on the inner wall of the guide ring 481. An atomizing nozzle 484 is provided at the output end of the flow divider 483. The input end of the water inlet pipe 482 is connected to the inside of the spray assembly 200 through a water pump. The water pump is electrically connected to the power supply assembly 600 through a wire. The drive assembly 500 includes a drive shaft 510 connected to the dust suppression assembly 400. A turbine fan 520 is fitted on the outer wall of the drive shaft 510. A protective pipe 530 is installed at the input end of the turbine fan 520. A connecting ring 540 is provided on the outer wall of the drive shaft 510 at one end of the turbine fan 520. The thickness of the connecting ring 540 gradually decreases from the center to both ends. A fan 550 is fitted on the outer wall of the drive shaft 510 at the end of the connecting ring 540 away from the turbine fan 520.

[0062] In the above structure, when the operator controls the water pump to start working through the power supply component 600, the water pump delivers the solution inside the water storage tank 210 to the guide ring 481 through the water inlet pipe 482, and then transmits it to the atomizing nozzle 484 through the diverter block 483, and finally sprays the dust suppression solution from the atomizing nozzle 484.

[0063] To further expand the dust suppression range, the staff controlled the turbine fan 520 again via the power supply unit 600. The turbine fan 520 transmitted air to the inside of the air intake 420 through the protective cover 440. Since the air intake 420 is conical, the airflow that was already gathered by the turbine fan 520 is further concentrated towards the center. When the air enters the exhaust pipe 460 through the air intake 420, the exhaust pipe 460 is funnel-shaped, which causes the air entering the exhaust pipe 460 to flow quickly along the central axis of the exhaust pipe 460 and to absorb the surrounding air and propel it forward. At this time, the airflow is supplemented with sufficient air through the two rings of drainage holes 470 on the outer wall of the exhaust pipe 460. At the same time, the fan increases the airflow speed, so that the exhaust pipe 460 discharges a large-scale and strong airflow. This airflow carries the dust suppression solution to treat the surrounding environment.
