Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal device technology, and in particular to a dust removal device for construction sites. Background Technology
[0002] Dust pollution is a significant factor affecting the environmental quality of construction sites. To reduce dust concentration and improve the working environment, most construction sites are now equipped with spray-type dust collection devices.
[0003] The existing patent "CN 221846543 U A Dust Suppression Sprayer Frame" can adjust the height of the support rod through the lifting component, but the angle of the spray component cannot be adjusted. Since the dust distribution at the construction site is complex and diverse, the dust concentration and diffusion direction in different areas may be different, and it is not possible to flexibly adjust according to the actual wind direction, dust diffusion direction or work area.
[0004] Secondly, although it features symmetrical spray components on both sides of the support rod to achieve all-around dust suppression, in practical applications, if the spray head on the side closest to the wall is kept on during construction, it will not only waste water resources but may also create unnecessary slippery hazards for surrounding facilities or the ground.
[0005] Therefore, it is necessary to provide a dust removal device for construction sites to solve the problems mentioned in the background art. Utility Model Content
[0006] To address the aforementioned problems, this application provides a dust removal device for construction sites, which solves the issues of the non-adjustable angle of the spray components and the lack of selective spraying function mentioned in the background art.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means three or more.
[0029] Figures 1-5 A dust removal device for a construction site provided in this application includes: a stand 1 and an angle-adjustable spraying mechanism 4, wherein the stand 1 is equipped with a height-adjustable mechanism 2, the output end of the height-adjustable mechanism 2 is provided with a guide cylinder 3, and the guide cylinder 3 is equipped with the angle-adjustable spraying mechanism 4;
[0030] Specifically, the angle-adjustable spray mechanism 4 includes a fixed base 401 fixedly mounted on the upper end of the guide cylinder 3. Multiple second longitudinal guide shafts 402 are fixedly arranged in a circumferential array on the upper end of the fixed base 401, and the upper ends of each of the second longitudinal guide shafts 402 are fixedly mounted to a limiting seat 403. A second lead screw shaft 405 is rotatably mounted between the fixed base 401 and the limiting seat 403. A drive motor 404 is fixedly mounted on the lower end of the fixed base 401, and the output end of the drive motor 404 is connected to the second lead screw shaft. A guide seat 406 is vertically movable on the second longitudinal guide shaft 402 and a fixed base 405 is fixedly installed. The second lead screw shaft 405 is threadedly connected to the guide seat 406. A plurality of rocker arms 407 are rotatably and evenly arranged in the circumferential direction of the fixed base 401. A plurality of connecting rods 408 are rotatably and evenly arranged in the circumferential direction of the guide seat 406. The ends of the connecting rods 408 away from the guide seat 406 are all hinged to the rocker arms 407. A spray assembly 409 is fixedly installed on each rocker arm 407.
[0031] With the above technical solution, after the dust removal device is moved to a specific position, when the angle of the spray assembly 409 needs to be adjusted, the drive motor 404 is started. The drive motor 404 drives the second lead screw shaft 405 to rotate. Driven by the second lead screw shaft 405, the guide seat 406 moves up and down along the second longitudinal guide shaft 402. The connecting rod 408 drives the rocker arm 407 to deflect and adjusts the rocker arm 407 to a specific angle. After water is supplied into the spray assembly 409, the water flow is sprayed out from the spray assembly 409 to carry out dust suppression.
[0032] Based on the above technical solution, the deflection angle of the rocker arm 407 can be flexibly adjusted according to the specific construction stage by the drive motor 404, so that the angle of the spray assembly 409 is adjustable, thereby effectively suppressing dust, reducing the concentration of suspended particulate matter in the air at the construction site, and meeting diverse needs.
[0033] In one possible implementation, the spray assembly 409 includes a first fixing block 4091 and a second fixing block 4092 symmetrically fixed on the rocker arm 407. A spray pipe 4093 is fixedly disposed between the first fixing block 4091 and the second fixing block 4092. A plurality of spray heads 4094 are uniformly fixedly disposed on the spray pipe 4093 located between the first fixing block 4091 and the second fixing block 4092, and a water valve 4095 is fixedly disposed on each of the spray pipes 4093 extending out of the second fixing block 4092.
[0034] It should be added that the lengths of the rocker arm 407 and the spray pipe 4093 can be customized according to actual needs. For example, when the dust suppression area is large, the device equipped with a relatively long rocker arm 407 and spray pipe 4093 should be selected for dust suppression operations; when the dust suppression area is small, the device equipped with a relatively short rocker arm 407 and spray pipe 4093 should be selected for dust suppression operations.
[0035] Based on the above technical solution, when the spray pipe 4093 is used selectively, the corresponding water valve 4095 is opened or closed, and a specific spray pipe 4093 is selectively opened according to actual needs, so as to connect or close the water flow with the spray pipe 4093, thereby avoiding unnecessary spraying, ensuring that water resources are only used in areas that really need dust suppression, effectively reducing water waste and improving water resource utilization efficiency.
[0036] In one possible implementation, the water valves 4095 are all connected to the outlet of the water pump via hoses, and the inlet of the water pump is connected to the water tank (not shown in the figure). That is, after the adjustment is completed, the water pump is turned on, and the water flow is supplied sequentially along the water tank, water pump, hose, and water valves 4095 to each spray pipe 4093. The water flow is then sprayed out from the corresponding spray head 4094 to suppress dust.
[0037] In one possible implementation, the stand 1 includes: a support base 101, on which a plurality of vertical shafts 102 are uniformly fixed in the circumferential direction, and a support shaft 103 is fixedly installed at the lower end of each vertical shaft 102, and a ground mat 104 is fixedly installed at the lower end of each support shaft 103. The arrangement of the stand 1 can increase the stability of the overall device.
[0038] In one possible implementation, the height-adjustable mechanism 2 includes a plurality of first longitudinal guide shafts 201 fixedly arranged in a circumferential array on the upper end of the support base 101. A lifting motor 203 is fixedly arranged at the lower end of the support base 101, and a first lead screw shaft 204 is fixedly arranged at the output end of the lifting motor 203. After the lifting motor 203 is started, it can drive the first lead screw shaft 204 to rotate.
[0039] In one possible implementation, a first limiting cap 202 is fixedly provided at the upper end of the first longitudinal guide shaft 201, and a second limiting cap 205 is fixedly provided at the upper end of the first lead screw shaft 204. The provision of the first limiting cap 202 and the second limiting cap 205 can limit the raising of the guide cylinder 3.
[0040] In one possible implementation, the guide cylinder 3 is vertically movable and mounted on the first longitudinal guide shaft 201 located between the first limiting cap 202 and the support base 101, and a sleeve 206 is fixedly mounted at the lower end of the guide cylinder 3. The first lead screw shaft 204 is threadedly connected to the sleeve 206 and passes through the guide cylinder 3.
[0041] Using the above technical solution, when the height of the angle-adjustable spray mechanism 4 is adjusted, the lifting motor 203 is started, the lifting motor 203 drives the first lead screw shaft 204 to rotate, and the sleeve 206 is driven by the first lead screw shaft 204. The guide cylinder 3 and the sleeve 206 are raised and lowered along the first lead screw shaft 204, and the guide cylinder 3 is adjusted to a specific height.
[0042] In one possible implementation, both the lifting motor 203 and the drive motor 404 are provided with waterproof covers (not shown in the figure) to prevent water from entering the lifting motor 203 and the drive motor 404 and affecting their normal operation.
[0043] Working principle:
[0044] After the staff moved the dust removal device to a specific location, they supplied water to the water tank.
[0045] When adjusting the height of the spray pipe 4093, the lifting motor 203 is started. The lifting motor 203 drives the first lead screw shaft 204 to rotate. The sleeve 206 is driven by the first lead screw shaft 204. The guide cylinder 3 and the sleeve 206 are raised and lowered along the first lead screw shaft 204, and the guide cylinder 3 is adjusted to a specific height.
[0046] When the angle of the spray pipe 4093 is adjusted, the drive motor 404 is started. The drive motor 404 drives the second lead screw shaft 405 to rotate. The guide seat 406 is driven by the second lead screw shaft 405 and moves up and down along the second longitudinal guide shaft 402. The connecting rod 408 drives the rocker arm 407 to deflect and adjusts the rocker arm 407 to a specific angle.
[0047] When the sprinkler pipe 4093 is used selectively, open or close the corresponding water valve 4095.
[0048] In actual use, after the adjustment is completed, the water pump is turned on, and the water flow is supplied sequentially along the water tank, water pump, hose, and water valve 4095 to each spray pipe 4093. The water flow is then sprayed out from the corresponding spray head 4094 to carry out dust suppression.
[0049] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
