Description

Technical Field

[0001] The invention relates to the technical field of dust reduction in highway engineering construction, in particular to a dust reduction device in highway engineering construction. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. During the construction of highway projects, some illegal buildings need to be demolished.

Therefore, dust reduction treatment is required to effectively purify the construction environment.

DETAILED DESCRIPTION

[0033] 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.

[0034] See also Figure 1-8A highway engineering construction dust reduction device comprises a base 1, a water tank 2 fixedly connected to the top of the base 1, a dust reduction mechanism 3 arranged outside the water tank 2, a dust suction shell 4 fixedly connected to the outside of the base 1, a dust collection box 5 fixedly connected to the top of the base 1, and a controller 9 fixedly installed on the front of the water tank 2. The dust reduction mechanism 3 comprises a booster pump 31, a connecting pipe 32, a hose 33, a spray pipe 34, and an atomizing nozzle 35. The back of the water tank 2 is fixedly connected with a water injection pipe.

[0035] Among them, the booster pump 31 is fixedly installed on the outside of the water tank 2, the atomizing nozzle 35 is fixedly connected to the outside of the spray pipe 34, the hose 33 is fixedly connected between the output end of the booster pump 31 and the spray pipe 34, and the connecting pipe 32 is fixedly connected between the input end of the booster pump 31 and the water tank 2.

[0036] In order to realize the reciprocating movement of the spray pipe 34 so that the water mist can fully cover the construction area, in this embodiment, Figure 2 - Figure 3 As shown, the upper surface of the water tank 2 is provided with a moving mechanism 6 for reciprocating the spray pipe 34, and the moving mechanism 6 includes a mounting seat 61, a reduction motor 62, a turntable 63, a crank 64, a mounting sleeve 65 and a limit seat 66. Under the driving action of the moving mechanism 6, the spray pipe 34 is reciprocated back and forth, which effectively ensures that the water mist can fully cover the construction area, and can more effectively combine with and settle the dust particles in the air, thereby further improving the utilization efficiency of water resources. Using the dust reduction mechanism 3 and allowing the spray pipe 34 to reciprocate back and forth, by adjusting the moving speed and spray volume of the spray pipe 34, it is possible to flexibly respond to the dust changes at the construction site, ensure that the dust reduction effect is always maintained in the best state, and control the dust at the construction site at the same time, which has many significant advantages in highway engineering construction. These advantages not only help to reduce dust concentration and improve the construction environment, but also improve the utilization efficiency of water resources and adapt to different working conditions, providing strong support for the green construction and sustainable development of highway engineering.

[0037] The reduction motor 62 is fixedly installed inside the mounting seat 61 , the turntable 63 is fixedly connected to the output shaft of the reduction motor 62 , and the crank 64 is hinged to the upper surface of the turntable 63 .

[0038] Specifically, the mounting sleeve 65 is fixedly connected to the end of the crank 64 away from the turntable 63, the spray tube 34 is fixedly installed inside the mounting sleeve 65, the limiting seat 66 is fixedly connected to the top of the mounting seat 61, and the limiting seat 66 has a moving opening adapted to the crank 64 inside, and the crank 64 is slidably connected to the inside of the limiting seat 66. The crank 64 is swingably connected to the top of the turntable 63. By providing the limiting seat 66, it is convenient to limit the crank 64 when it moves.

[0039] In addition, the dust reduction mechanism 3 is equipped with an intelligent control module, which can automatically adjust the spray time and spray volume according to the dust conditions at the construction site, thereby improving the dust reduction efficiency and saving water resources.

[0040] When this embodiment is in use, the controller 9 starts the reduction motor 62 to drive the turntable 63, the crank 64 and the mounting sleeve 65 to perform transmission cooperation, so that the spray pipe 34 and the atomizing nozzle 35 move back and forth, thereby quickly responding and suppressing the spread of dust, and achieving a deeper dust reduction effect. Compared with static spraying, the dynamic spraying method can spray water mist more evenly, so that dust particles in the air can be more effectively adsorbed and settled, thereby quickly reducing the dust concentration in the air.

[0041] In order to realize the linkage between the negative pressure fan 73 and the cleaning roller 71 when working, so as to absorb and collect the dust particles on the ground, in this embodiment, as shown in FIG. Figure 4 - Figure 7 As shown, the dust collecting shell 4 is provided with a dust removing mechanism 7 for cooperating with the dust collecting box 5 to perform dust suppression, and the dust removing mechanism 7 comprises a cleaning roller 71, a mounting shell 72, a negative pressure fan 73, a rotating shaft 74, a transmission wheel 75, a driven wheel 76, a synchronous belt 77 and a dust collecting pipe 78. By utilizing the negative pressure fan 73 to work in conjunction with the cleaning roller 71, negative pressure is generated inside the dust collecting box 5, thereby achieving an efficient dust suppression effect.

[0042] The cleaning roller 71 is rotatably connected to the inside of the dust collecting shell 4 and extends to the outside thereof, the mounting shell 72 is fixedly connected to the outside of the dust collecting box 5 , and the negative pressure fan 73 is rotatably mounted inside the mounting shell 72 .

[0043] Specifically, the rotating shaft 74 is fixedly connected to the axis of the negative pressure fan 73, the driving wheel 75 is fixedly installed on the end of the rotating shaft 74 away from the negative pressure fan 73, the driven wheel 76 is fixedly installed on the end of the cleaning roller 71 away from the dust collection shell 4, the synchronous belt 77 is transmission-connected to the outside of the driving wheel 75 and the driven wheel 76, and the dust collection pipe 78 is fixedly connected between the dust collection shell 4 and the dust collecting box 5.

[0044] It should be noted that the dust removal mechanism 7 also includes a mounting frame 79, a slide 710 and a filter plate 711. The mounting frame 79 is fixedly installed inside the dust box 5. There are two slides 710, and the two slides 710 are symmetrically connected to the inside of the mounting frame 79. The filter plate 711 is slidably connected to the inside of the two slides 710. The inside of the dust box 5 is provided with a movable opening adapted to the filter plate 711.

[0045] When this embodiment is in use, the negative pressure fan 73 is started by the controller 9 to drive the driving wheel 75, the driven wheel 76 and the synchronous belt 77 to cooperate with each other, so that the cleaning roller 71 rolls and contacts the ground, and can directly remove the dust particles attached to the ground. At the same time, the negative pressure fan 73 is used to generate negative pressure inside the dust box 5, and the fine particles suspended in the air after the cleaning roller 71 is disturbed are adsorbed by the dust suction shell 4 and the dust suction pipe 78, and the dust particles on the ground are collected by the filter plate 711. The design of the mounting frame 79 and the slide seat 710 makes the filter plate 711 detachable for easy replacement. Compared with the traditional water sprinkling dust reduction method, dust reduction using the cleaning roller 71 and the negative pressure fan 73 does not require a large amount of water, thereby reducing the consumption of water resources, which is particularly important for areas with water shortages and helps to achieve green construction and sustainable development. In addition, the noise generated by the cleaning roller 71 and the negative pressure fan 73 when working is relatively low, and will not cause excessive noise pollution to the residents and environment around the construction site. At the same time, according to the specific conditions of the construction site, the rolling frequency of the cleaning roller 71 and the suction force of the negative pressure fan 73 can be flexibly adjusted to meet different dust reduction needs. This flexibility enables the dust reduction device to better adapt to changes in the construction process.

[0046] In order to adjust the angle and height of the dust suppression mechanism 3 to meet different working conditions, in this embodiment, Figure 8 As shown, an adjusting mechanism 8 for rotating and lifting the dust reduction mechanism 3 is provided on the upper surface of the water tank 2. The adjusting mechanism 8 includes a servo motor 81 fixedly mounted on the top of the water tank 2 and a mounting cylinder 83 rotatably connected to the top of the water tank 2. A transmission gear 82 is fixedly connected to the output shaft of the servo motor 81, and a driven gear 84 meshing with the transmission gear 82 is fixedly connected to the outside of the mounting cylinder 83.

[0047] Among them, an electric push rod 85 is fixedly installed on the inner bottom wall of the mounting cylinder 83, a connecting plate 86 is fixedly connected to the output shaft of the electric push rod 85, an adjusting rod 87 extending to the inside of the mounting cylinder 83 is fixedly connected to the top of the connecting plate 86, a movable opening adapted to the adjusting rod 87 is opened inside the mounting cylinder 83, and the mounting seat 61 is fixedly connected to the top of the adjusting rod 87.

[0048] When this embodiment is in use, the servo motor 81 is started by the controller 9 to drive the transmission gear 82 to rotate, so that the transmission gear 82 engages with the driven gear 84 to drive the mounting tube 83 to rotate, thereby realizing the angle adjustment of the dust reduction mechanism 3. The electric push rod 85 is started by the controller 9 to extend and retract to drive the connecting plate 86 and the adjusting rod 87 to be raised and lowered, thereby realizing the height adjustment of the dust reduction mechanism 3. Through the coordinated use of the adjusting mechanism 8 and the moving mechanism 6, the dust reduction efficiency is improved while saving water resources.

[0049] In this embodiment, if Figure 1 As shown, two vertical poles 10 are fixedly connected to the top of the base 1, a handle 11 is fixedly connected between the two vertical poles 10, and four moving wheels 12 are rotatably installed at the bottom of the base 1. By installing the vertical poles 10, the moving wheels 12 and the handle 11, the overall mobility of the device is improved, the device is easy to move, and the dust reduction efficiency is improved.

[0050] The working principle of the above embodiment is:

[0051] When in use, the reduction motor 62 is started by the controller 9 to drive the turntable 63, the crank 64 and the mounting sleeve 65 to cooperate with each other, so that the spray pipe 34 and the atomizing nozzle 35 move back and forth, and the water inside the water tank 2 is pumped into the spray pipe 34 through the booster pump 31 to be sprayed out through the atomizing nozzle 35. At the same time, the negative pressure fan 73 is started to work, driving the transmission wheel 75, the driven wheel 76 and the synchronous belt 77 to cooperate with each other, so that the cleaning roller 71 rolls and contacts the ground, which can directly remove the dust particles attached to the ground. At the same time, the negative pressure fan 73 is used to generate negative pressure inside the dust collecting box 5, and the suction The dust shell 4 and the dust suction pipe 78 absorb the fine particles suspended in the air after being disturbed by the cleaning roller 71 and collect the dust particles on the ground through the filter plate 711. The design of the mounting frame 79 and the slide seat 710 makes the filter plate 711 detachable for easy replacement; the servo motor 81 is started by the controller 9 to drive the transmission gear 82 to rotate, so that the transmission gear 82 engages with the driven gear 84 to drive the mounting cylinder 83 to rotate, thereby realizing the angle adjustment of the dust reduction mechanism 3; the electric push rod 85 is started by the controller 9 to extend and retract to drive the connecting plate 86 and the adjusting rod 87 to be raised and lowered, thereby realizing the height adjustment of the dust reduction mechanism 3.
