[0002] During road construction, fencing boards are installed on the roadside to separate the road construction site from the external roads. A large amount of dust is generated during road construction. When construction vehicles enter and exit the site and when it is windy, the dust will flow with the air to the external roads, affecting the travel of vehicles and pedestrians. Therefore, a spraying system is often installed on the fencing boards to alleviate dust by spraying water. However, when construction vehicles enter and exit the construction site and when it is windy, the wind will limit the spraying range of the spraying water, and the wind will easily blow the water mist to the external roads. Non-motorized vehicle lanes are generally close to the fencing boards, and people driving non-motorized vehicles and pedestrians pass by. The water mist blown outside the fencing boards will affect the passage of non-motorized vehicles and pedestrians, posing a major traffic hazard.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 9 The present invention provides a technical solution: a dust reduction device with adjustable dust reduction area for road construction, comprising a baffle plate 1, a base 2, a pipe 3, a nozzle 4, a detection mechanism, a driving mechanism and a water pressure conversion mechanism; the base 2 is attached to the baffle plate 1; the pipe 3 is rotatably mounted on the base 2 and connected to an external water pipe for conveying spraying water; a plurality of nozzles 4 are provided, and the plurality of nozzles 4 are equidistantly rotatably mounted on the pipe 3 and connected to the pipe 3; the detection mechanism is installed in the base 2 and is used to detect wind direction; the driving mechanism is installed on the side of the pipe 3 and can adjust the inclination angles of the pipe 3 and the nozzle 4 according to the detection results of the detection mechanism, and adjust the spraying direction of the spraying water; the water pressure conversion mechanism is arranged on the side of the pipe 3 and can change the water pressure when the nozzle 4 sprays water, thereby adjusting the spraying area.

[0019] When installing the dust suppression device of the present invention, the base 2 is installed on the enclosure plate 1, and then the pipe 3 is connected to the external water pipe. The water pipe transports the spray water into the pipe 3, and then the water in the pipe 3 is sprayed out from the nozzle 4, and the water droplets carry the dust in the air and fall to the ground, which has the effect of dust suppression; in the initial state, the pipe 3 is at an angle of 45° to the construction road surface; in windy weather, the detection mechanism can detect the direction of the wind, and then the detection mechanism can cooperate with the driving mechanism to adjust the inclination angle of the pipe 3 and the nozzle 4; specifically, Figure 8 As shown, when the wind force is F1, the wind direction blows toward the inside of the baffle plate 1, and the spray water will be concentrated in the middle of the construction area under the action of the wind. At this time, the driving mechanism will drive the pipe 3 to rotate at an angle corresponding to f1, and the angle between the pipe 3 and the construction road surface will increase, thereby offsetting the wind force and keeping the spray water drop range in the original area; when the wind force is F2, the wind direction blows toward the outside of the baffle plate 1, and the spray water will be blown toward the non-motorized vehicle lane under the action of the wind. At this time, the driving mechanism will drive the pipe 3 to rotate at an angle corresponding to f2, and the angle between the pipe 3 and the construction road surface will decrease, and the water mist sprayed by the nozzle 4 can quickly fall on the construction road surface, thereby preventing the wind from blowing the spray water into the non-motorized vehicle lane and affecting the passage of non-motorized vehicles and pedestrians; as shown Fig. 9As shown, when the wind force is F3, the wind direction blows toward the left side of the baffle plate 1, and the spraying direction of the nozzle 4 will be offset under the action of the wind. At this time, the driving mechanism will drive the nozzle 4 to rotate at an angle corresponding to f3, and the nozzle 4 will rotate to the right, thereby offsetting the influence of the wind on the spraying range, so that the spraying water drop range continues to remain in the original area; when the wind force is F4, the wind direction blows toward the right side of the baffle plate 1, and the spraying direction of the nozzle 4 will be offset under the action of the wind. At this time, the driving mechanism will drive the nozzle 4 to rotate at an angle corresponding to f4, and the nozzle 4 will rotate to the left, thereby offsetting the influence of the wind on the spraying range, so that the spraying water drop range continues to remain in the original area; the water pressure conversion mechanism can change the pressure of the nozzle 4 when spraying water, so that the spraying range of the water mist can be adjusted in windy weather, so that the dust in the air can better follow the water mist to fall to the ground.

[0020] Specifically, Figure 2 As shown, the detection mechanism includes: a detection head 5, four pressure plates 7 and an extrusion component 9; the detection head 5 is installed in the middle of the base 2, and the bottom end of the detection head 5 is connected to the base 2 through an elastic element 6; the four pressure plates 7 are distributed in a circular array about the detection head 5; one end of the pressure plate 7 is rotatably connected to the base 2, and the other end is hinged with a stop 8; the extrusion component 9 is fixedly installed in the middle of the detection head 5; the stop 8 is in contact with the outer wall of the extrusion component 9; when the detection head 5 is tilted under the action of wind, the extrusion component 9 can cooperate with the stop 8 to squeeze the pressure plate 7 at the same position as the wind direction.

[0021] In windy weather, the wind will drive the detection head 5 to twist, and the twisting direction of the detection head 5 is the same as the wind direction. When the detection head 5 twists, it will squeeze the stopper 8 located in its twisting direction through the squeezing component 9; the stopper 8 will drive the pressure plate 7 to bend, so that the wind direction can be detected.

[0022] Specifically, the pressing plate 7 is made of elastic steel strip material and has an arc shape with high ends and a low middle. Setting the pressing plate 7 to have an arc shape with high ends and a low middle can ensure that when the detection head 5 is twisted, it will squeeze the pressing plate 7 to bend downward.

[0023] Specifically, the extrusion component 9 is configured to be a truncated cone that is wide at the top and narrow at the bottom, so that it can better abut against the butt 8 . Meanwhile, when the detection head 5 is twisted, the extrusion component 9 can better transmit the force to the butt 8 .

[0024] Specifically, Figure 2 , Figure 4-Figure 6 , Figure 8 and Fig. 9As shown, the driving mechanism includes a hydraulic cylinder 10, two first gears 11 and multiple second gears 12; the hydraulic cylinders 10 are arranged in the same number as the pressure plates 7, the bottom ends of the four hydraulic cylinders 10 are fixedly connected to the base 2, and the telescopic ends are respectively located below the middle of the four pressure plates 7; one-way bearings 13 are installed on the inner walls of the two first gears 11, and the two one-way bearings 13 can rotate in opposite directions; the two first gears 11 are meshed with two first racks 14, and the two first racks 14 are centrally symmetrically distributed about the center of the first gear 11; the first racks 14 are fixedly connected to the first piston rods 15, and the first piston rods 15 are slidably connected to the first cylinder bodies 16; the left and right first cylinder bodies 16 are respectively connected to the front and rear hydraulic cylinders 1 through the first hoses 17 0 is connected; a plurality of second gears 12 are respectively fixedly mounted on the rotating shaft of the nozzle 4, and a plurality of second gears 12 are commonly meshed with a second rack 18; the second rack 18 is elastically slidably connected to the pipeline 3; two symmetrically arranged wedge-shaped driving blocks 19 are arranged on the side of the second rack 18; the wedge-shaped driving blocks 19 are all slidably connected to the pipeline 3, and the wedge-shaped driving blocks 19 are all rotatably connected to the connecting rods 20, and the connecting rods 20 are rotatably connected to the sliders 21 at the ends away from the wedge-shaped driving blocks 19; the sliders 21 are all fixedly connected to the second piston rods 22; the second piston rods 22 are all slidably connected to the second cylinder bodies 23; the second cylinder bodies 23 are fixedly connected to the pipeline 3; the left and right second cylinder bodies 23 are respectively connected to the right and left hydraulic cylinders 10 through the second hoses 24.

[0025] When the wind force is in the front-to-back direction (i.e., F1 or F2), the detection head 5 will drive the front or rear pressure plate 7 to bend downward, and the pressure plate 7 will drive the free end of the front or rear hydraulic cylinder 10 to move downward, and the hydraulic oil in the hydraulic cylinder 10 will enter the first cylinder bodies 16 on the left and right sides through the first hose 17, and the first piston rod 15 will extend forward, and the first piston rod 15 will drive the first rack 14 to move forward; Figure 5 and Figure 8 As shown, when the wind force is F1 (the wind blows forward, that is, the inside of the baffle 1), Figure 5 The first rack 14 on the right side will move forward, and the first rack 14 will drive the first gear 11 to rotate; at this time, the first gear 11 on the right side will drive the pipe 3 to lift up a certain angle through the one-way bearing 13; on the contrary, when the wind force is F2 (the wind blows to the rear side, that is, the outside of the baffle 1), Figure 5The first rack 14 on the left side will move forward, and the first rack 14 will drive the first gear 11 to rotate; at this time, the first gear 11 on the left side will drive the pipe 3 to rotate downward by a certain angle through the one-way bearing 13; since the two one-way bearings 13 can rotate in opposite directions, the first gears 11 on the left and right sides can respectively drive the pipe 3 to rotate and will not drive the other first gear 11 to rotate; it should be noted that the rotation angle of the pipe 3 will change in real time with the size of the wind force. When the wind force is greater, the rotation angle of the pipe 3 is greater, which can better ensure that the sprayed water can fall within the specified range; and the maximum rotation angle can be adjusted according to the meshing length of the first rack 14 and the first gear 11, which can ensure that the pipe 3 does not rotate excessively; such as Figure 4 , Figure 6 and Fig. 9 As shown, when the wind force is F3 (the wind blows to the left), the detection head 5 will drive the left pressure plate 7 to bend downward, and the pressure plate 7 will drive the free end of the left hydraulic cylinder 10 to move downward, and the hydraulic oil in the hydraulic cylinder 10 will enter the second cylinder body 23 on the right through the second hose 17. At this time, the second piston rod 22 on the right will move rightward and be collected in the second cylinder body 23. The second piston rod 22 on the right will drive the bottom end of the right connecting rod 20 to move rightward synchronously through the slider 21, and the top of the right connecting rod 20 will drive the right wedge-shaped driving block 19 to move downward, and the right wedge-shaped driving block 19 will drive the second rack 18 to move leftward through the inclined surface; the second rack 18 will drive the nozzle 4 to rotate rightward through the second gear 12, and the wind force can blow the spray water to the area where it should be sprayed; when the wind force is F4 (the wind blows to the right), it is the opposite; similarly, the rotation amplitude of the nozzle 4 is proportional to the magnitude of the wind force and is within a certain range, which can better ensure that the spray water can fall within the specified range.

[0026] Specifically, Figure 3 , Figure 4 , Figure 7 as well as Figure 8 As shown, the water pressure conversion mechanism includes an extrusion tube 25 installed in the nozzle 4; the extrusion tube 25 is set to be a funnel shape that is wide at both ends and narrow in the middle; a tightening sleeve 26 is fixedly connected to the outer wall of the extrusion tube 25; one end of the tightening sleeve 26 passes through the side wall of the nozzle 4 and extends to the outside of the nozzle 4; two adjacent tightening sleeves 26 are fixedly connected by a first steel rope 27; a second steel rope 28 is fixedly connected to the rightmost tightening sleeve 26, and the second steel rope 28 is fixedly connected to the base 2 at one end away from the rightmost tightening sleeve 26.

[0027] When the pipe 3 flips in the direction of f2, since the end of the second steel rope 28 away from the nozzle 4 is connected to the base 2, the other end of the second steel rope 28 will drive the tightening sleeve 26 on the far right to tighten. At this time, under the action of the first steel rope 27, all the tightening sleeves 26 will be tightened synchronously; after the tightening sleeve 26 is tightened, the cross-sectional area of ​​the middle section of the extrusion tube 25 is reduced. At this time, the water pressure increases, the dust reduction water spraying area can be increased, and the influence of wind on the dust reduction range can also be offset; compared with the use of a booster pump, the water pressure conversion mechanism of this embodiment can take effect immediately with the rotation of the pipe 3, and the boost amplitude of the spraying water can increase with the rotation angle of the pipe 3.

[0028] Specifically, Figure 1 As shown, the water pressure conversion mechanism includes a booster pump 29, which is connected to the pipeline 3. The booster pump 29 can directly increase the pressure of water in the pipeline 3 when it is sprayed out. Compared with using the extrusion tube 25 and the tightening sleeve 26, the booster pump 29 has a simple structure and can change the water pressure even in windless weather, thereby adjusting the spraying area.

[0029] Specifically, a guide rail 30 is installed at the bottom end of the base 2, and the guide rail 30 can slide on the enclosure plate 1; the guide rail 30 is driven by a roller; the guide rail 30 can be driven by the roller to slide on the enclosure plate 1, so that the pipe 3 and the nozzle 4 can be moved for spraying, which can improve the spraying efficiency and area.
