Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and in particular relates to a dust removal device for building construction. Background Technology

[0002] During construction, various operations such as earthwork excavation, material transportation, concrete mixing, and construction waste removal generate significant amounts of dust. This dust not only pollutes the surrounding atmosphere but also poses a risk to the respiratory health of construction workers. Furthermore, it reduces visibility at the construction site and surrounding areas, creating potential safety hazards. To effectively control construction dust pollution, various dust suppression devices are widely used at construction sites. Among these, water mist dust suppression devices, due to their simple structure, low operating costs, and environmental friendliness (no secondary pollution), have become one of the mainstream dust control equipment and are widely used in various construction scenarios, including residential buildings, municipal roads, and bridge projects.

[0003] However, existing water mist dust suppression devices used in construction projects still have significant technical shortcomings in practical applications, making it difficult to meet the high-efficiency dust removal needs in complex construction scenarios: the atomizing nozzles of existing devices are mostly fixed installations, and their air spray angle cannot be flexibly adjusted once installed, resulting in a fixed water mist spray direction. This makes it impossible to make targeted adjustments based on the diffusion direction and concentration area of ​​dust at the construction site. Moreover, due to the limitation of the fixed spray angle, coupled with the limited range of the atomizing nozzles in some devices, the coverage area of ​​the water mist is small, making it difficult to fully cover large construction areas and effectively capture highly dispersed dust with a wide diffusion range.

[0004] The aforementioned two shortcomings directly result in the low dust removal efficiency of existing water mist dust suppression devices, making it impossible to quickly and efficiently control construction dust pollution and failing to meet the high standards for dust control in current construction projects. Therefore, there is an urgent need to improve existing dust removal devices and provide a dust removal device specifically designed for construction projects. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a dust removal device for construction engineering that is reasonably designed, simple in structure, has an adjustable spray angle, and a wider coverage range, thereby solving the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dust removal device for construction engineering includes:

[0008] The housing has a vertical shaft mounted on the top bearing at the left end, a mounting platform fixed to the top of the vertical shaft, a gear fixedly sleeved on the outer side of the bottom end of the vertical shaft, a bracket fixed above the mounting platform, and a fog cannon hinged to the top of the bracket.

[0009] There are two crossbars, both of which are fixed to the upper right inner side of the box. A toothed plate is slidably mounted on the outer side of the crossbar. The toothed plate is located on the right side of the gear and the two mesh with each other for transmission. A protruding post is fixed in the middle of the right side wall of the toothed plate.

[0010] A reciprocating drive mechanism includes a sleeve and a guide groove. The guide groove is designed in an inclined spiral shape and is symmetrically opened on the outer surface of the sleeve. The two guide grooves are interconnected.

[0011] In a preferred embodiment, self-locking casters are installed at the four right corners of the bottom of the box, and a partition is fixedly installed inside the box.

[0012] In a preferred embodiment, the interior of the box is divided into two cavities by the partition plate, with the upper cavity being an empty cavity and the lower cavity being a water storage cavity.

[0013] In a preferred embodiment, the system also includes an electric telescopic rod, the two ends of which are hinged to the mounting platform and the fog cannon, respectively.

[0014] In a preferred embodiment, the crossbar is symmetrically fixed with sleeves inside, and two sleeves are respectively fitted onto the outer sides of the two crossbars. A number of rolling steel balls are installed at equal intervals along the length of the sleeves, and the rolling steel balls abut against and fit against the outer surface of the crossbar.

[0015] In a preferred embodiment, the end of the protrusion away from the toothed plate is guided and slidably located in the guide groove, and the toothed plate forms a reciprocating horizontal sliding structure through the sleeve.

[0016] In a preferred embodiment, the reciprocating drive mechanism further includes a drive shaft and a drive motor. The drive shaft is located on the right side of the cavity and is connected to the housing bearing. The sleeve is fixed at the middle position of the drive shaft. The drive motor is fixed on the right front outer wall of the housing, and the output end of the drive motor is fixedly connected to the front end of the drive shaft.

[0017] In a preferred embodiment, a water pumping mechanism is also included, which includes a water pump, a hose, and a water pumping pipe. The water pump is fixed to the upper right of the housing. The output end of the water pump is connected to the water inlet of the fog cannon through a hose. The input end of the water pump is fixedly connected to the water pumping pipe, and the bottom end of the water pumping pipe is fixedly connected to the outlet of the water storage chamber.

[0018] In a preferred embodiment, a controller is fixedly installed on the front outer wall of the housing, and the fog cannon, electric telescopic rod, drive motor, and water pump are all electrically connected to the controller.

[0019] In a preferred embodiment, a water inlet pipe is embedded and fixed on the left side wall of the box, the bottom end of the water inlet pipe is connected to the water storage cavity, and a cap is threaded on the outer side of the top end of the water inlet pipe.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] In the solution of this invention:

[0022] This invention controls the drive shaft to rotate the sleeve at a constant speed by starting the drive motor. Two interconnected inclined spiral guide grooves on the surface of the sleeve cooperate with the protruding column to form a stable squeezing and pushing force on the protruding column. This facilitates the reciprocating horizontal sliding of the toothed plate along the crossbar. With the meshing transmission of the toothed plate and gears, it is easy to control the vertical shaft, mounting platform, bracket and fog cannon to swing back and forth at a small angle. This can effectively expand the spray dust suppression coverage of the fog cannon, making it easy to fully cover the construction area of ​​the building project. It can achieve efficient capture and suppression of dust with strong dispersion and wide diffusion range, significantly improve the overall dust removal effect, and solve the technical problems of limited coverage and low dust removal efficiency of existing devices.

[0023] In response to the complex scenarios of dust dispersion direction and concentration area at construction sites, this invention uses the telescopic movement of an electric telescopic rod to drive the fog cannon to rotate flexibly vertically at the top of the support. This allows for targeted adjustment of the fog cannon's spray angle based on the actual dispersion direction and concentration area of ​​the dust on site, ensuring that the water mist spray direction matches the dust dispersion path. This meets the high-efficiency dust removal needs of different construction scenarios and improves the device's adaptability and targeted dust removal capabilities.

[0024] This invention features sleeves fixedly installed inside the toothed plate, each corresponding to and slidably fitted to a crossbar. Several rolling steel balls are equidistantly installed along the length of each sleeve. Through the rolling action of the steel balls, the sliding friction between the crossbar and the sleeve is efficiently converted into rolling friction. This significantly reduces frictional resistance between components, improves the smoothness and stability of the device's operation, and prevents jamming. Furthermore, it effectively reduces wear on the crossbar and sleeve, extends the service life of the components, ensures stable and reliable operation of the device during long-term continuous operation, and reduces equipment maintenance costs.

[0033] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0034] like Figure 1-5 As shown, the present invention is based on a dust removal device for construction engineering, which includes:

[0035] Box 1, a vertical shaft 3 is installed on the top bearing of the left end of box 1, a mounting platform 4 is fixed to the top of the vertical shaft 3, a gear 8 is fixedly sleeved on the outer side of the bottom end of the vertical shaft 3, a bracket 5 is fixed above the mounting platform 4, and a fog cannon 6 is hinged to the top of the bracket 5.

[0036] There are two crossbars 9, both of which are fixed to the upper right inner side of the housing 1. A toothed plate 10 is slidably mounted on the outer side of the crossbar 9. The toothed plate 10 is located on the right side of the gear 8 and the two mesh and drive each other. A protruding post 11 is fixed in the middle of the right side wall of the toothed plate 10.

[0037] The reciprocating drive mechanism includes a sleeve 13 and a guide groove 14. The guide groove 14 is designed in an inclined spiral shape and is symmetrically opened on the outer surface of the sleeve 13. The two guide grooves 14 are interconnected.

[0038] Based on the above structure, self-locking casters 2 are installed at the four right angles of the bottom of the box 1, and a partition plate 16 is fixedly installed inside the box 1.

[0039] Based on the above structure, the interior of the box 1 is divided into two inner cavities by a partition plate 16. The upper inner cavity is a hollow cavity 17, and the lower inner cavity is a water storage cavity 18.

[0040] In this embodiment, the partition plate 16 is used to facilitate the division of the internal space of the box 1.

[0041] Based on the above structure, it also includes an electric telescopic rod 7, the two ends of which are hinged to the mounting platform 4 and the fog cannon 6, respectively.

[0042] In this embodiment, the extension and retraction of the electric telescopic rod 7 can drive the fog cannon 6 to rotate flexibly vertically at the top of the bracket 5, which facilitates targeted control of the fog cannon 6's air spray dust suppression angle.

[0043] Based on the above structure, sleeves 23 are fixedly and symmetrically inside the crossbar 9. The two sleeves 23 are respectively sleeved on the outside of the two crossbars 9. A number of rolling steel balls 24 are installed at equal intervals along the length of the sleeves 23. The rolling steel balls 24 are in contact with and fit against the outer surface of the crossbar 9.

[0044] In this embodiment, the sliding friction between the crossbar 9 and the sleeve 23 can be efficiently converted into rolling friction by the rolling steel ball 24, which significantly reduces the frictional resistance between the components and improves the smoothness and stability of the device structure operation.

[0045] Based on the above structure, the end of the protruding post 11 away from the toothed plate 10 is guided and slidably located in the guide groove 14, and the toothed plate 10 forms a reciprocating horizontal sliding structure through the sleeve 13.

[0046] Based on the above structure, the reciprocating drive mechanism also includes a drive shaft 12 and a drive motor 15. The drive shaft 12 is located on the right side of the cavity 17 and is connected to the bearing of the housing 1. The sleeve 13 is fixed at the middle position of the drive shaft 12. The drive motor 15 is fixed on the right front outer wall of the housing 1, and the output end of the drive motor 15 is fixedly connected to the front end of the drive shaft 12.

[0047] In this embodiment, when the drive motor 15 is started to control the drive shaft 12 and the sleeve 13 to rotate, the inclined spiral guide groove 14 opened on the surface of the sleeve 13 is used to facilitate the push of the protrusion 11 to control the toothed plate 10 to move reciprocally horizontally along the crossbar 9.

[0048] Based on the above structure, a water pumping mechanism is also included. The water pumping mechanism includes a water pump 19, a hose 20, and a water pumping pipe 21. The water pump 19 is fixed to the upper right of the housing 1. The output end of the water pump 19 is connected to the water inlet of the fog cannon 6 through the hose 20. The input end of the water pump 19 is fixedly connected to the water pumping pipe 21. The bottom end of the water pumping pipe 21 is fixedly connected to the outlet of the water storage chamber 18.

[0049] In this embodiment, by turning on the water pump 19, it is convenient to draw out the clean water in the water storage chamber 18 through the water pumping pipe 21, and then deliver the clean water to the fog cannon 6 through the hose 20, so as to facilitate dust suppression operations.

[0050] Based on the above structure, a controller 22 is fixedly installed on the front outer wall of the housing 1. The fog cannon 6, electric telescopic pole 7, drive motor 15, and water pump 19 are all electrically connected to the controller 22.

[0051] In this embodiment, the controller 22 is used to facilitate the control of the operation of each electrical appliance.

[0052] Based on the above structure, a water inlet pipe 25 is embedded and fixed on the left side wall of the box 1. The bottom end of the water inlet pipe 25 is connected to the water storage chamber 18, and a cap 26 is threaded on the outer side of the top end of the water inlet pipe 25.

[0053] In this embodiment, the water inlet pipe 25 is used to facilitate the replenishment of water to the water storage chamber 18.

[0054] The working principle of this invention is as follows:

[0055] When in use, first push the device to the designated dust removal location within the construction site area, and fill the water storage chamber 18 with clean water through the water inlet pipe 25, and then tighten the cap 26 to seal the water inlet pipe 25.

[0056] Based on the actual height and concentrated area of ​​the dust suppression location, the electric telescopic rod 7 can be extended and retracted to drive the fog cannon 6 to rotate vertically at the top of the bracket 5. This allows for targeted adjustment of the fog cannon 6's air spray dust suppression angle, ensuring that the water mist spray direction matches the dust diffusion path. This meets the high-efficiency dust removal needs of different construction scenarios. Subsequently, the fog cannon 6 and water pump 19 can be turned on. Clean water is drawn out of the water storage chamber 18 through the water extraction pipe 21 and transported to the fog cannon 6 through the hose 20. Atomization spraying can then begin to achieve high-altitude dust suppression operations.

[0057] During the dust removal process, the drive motor 15 can be turned on to control the drive shaft 12 to drive the sleeve 13 to rotate at a constant speed. The two interconnected inclined spiral guide grooves 14 on the surface of the sleeve 13 facilitate the squeezing and pushing of the protrusion 11, so that the protrusion 11 drives the toothed plate 10 to slide back and forth horizontally along the crossbar 9. With the meshing transmission of the toothed plate 10 and the gear 8, it is easy to control the vertical shaft 3, the mounting platform 4, the bracket 5 and the fog cannon 6 to swing back and forth at a small angle. This can effectively expand the dust suppression coverage of the fog cannon 6, making it easy to fully cover the construction area of ​​the building project. It can achieve efficient capture and suppression of dust with strong dispersion and wide diffusion range, significantly improve the overall dust removal effect, and solve the technical problems of limited coverage and low dust removal efficiency of existing devices.

[0058] It should be noted that this device is powered by an external power source. The fog cannon 6, electric telescopic pole 7, drive motor 15, water pump 19 and controller 22 in this solution are all existing electrical products on the market. Their specific operating principles and control methods are mature existing technologies that are widely used in various fields. Therefore, they will not be described in detail in this article.
