[0001] The utility model relates to the technical field of dust reduction, in particular to a dust reduction device for civil engineering. Background Technique

[0002] Civil engineering mainly involves the planning, design, construction and maintenance of public works such as roads, bridges, dams, airports, water supply and drainage systems, etc. The key goal in this field is to efficiently utilize resources and technologies to complete engineering projects while ensuring safety and quality. In civil engineering, environmental protection and sustainable development are increasingly emphasized. For example, at the construction site, dust control is an important environmental protection measure. A dust reduction device is equipment used in civil engineering to control dust pollution at the construction site.

[0003] In a patent of a dust reduction device for civil engineering with the Chinese patent number CN221244462U, it includes four vertical rods. A base is fixed to the base of each vertical rod. A foldable connecting pipe is longitudinally arranged between the tops of two vertical rods on the same side. A plurality of spray pipes are horizontally arranged between the two groups of foldable connecting pipes. The spray pipes are communicated with the foldable connecting pipes. A plurality of spray heads are arranged at the bottom of each spray pipe. An installation structure for installing the foldable connecting pipe is longitudinally arranged on the two vertical rods on the same side. By setting the foldable connecting pipe, the foldable connecting pipe can be folded when not in use, thereby reducing the volume of the utility model and facilitating storage and transportation.

[0004] In the specific use of civil engineering, such a device achieves a larger dust reduction effect compared to a fog cannon machine. However, in the construction scenarios of civil engineering, it is often necessary to face a complex construction environment where the land may not be flat enough. The height adjustment function of this device is limited, resulting in poor adaptability to construction sites with a high degree of unevenness. Content of the Utility Model

[0005] In view of this, the utility model provides a dust reduction device for civil engineering, and the utility model can better adapt to different construction sites.

[0006] To solve the above technical problems, the utility model provides a dust reduction device for civil engineering, which includes supports. There are four supports. The top of the supports is provided with the same water spraying assembly. Adjusting components are arranged at the bottoms of the supports. The adjusting component includes a rotating column and a threaded cylinder. Sliding grooves are respectively opened in the middle of the supports. The rotating columns are respectively slidably connected to the middle of the sliding grooves. The outer diameter of the rotating column is equal to the inner diameter of the sliding groove. The bottoms of the supports are respectively rotatably connected to the threaded cylinders. Threads are respectively opened in the middle of the outer walls of the rotating columns. The threaded cylinders are respectively threadedly connected to the adjacent rotating columns. Support components are respectively arranged at the bottoms of the rotating columns. By adjusting the height of the supports to maintain the stability and appropriate spraying height of the water spraying assembly, the adjustable design can better adapt to different construction sites.

[0007] The adjusting assembly further includes a hexagonal column fixedly connected to the middle of the threaded cylinder; that is, using a wrench to fix the hexagonal column makes it convenient for the user to rotate the threaded cylinder and adjust the height of the support.

[0008] The adjusting assembly further includes a protective cover fixedly connected to the bottom of the threaded cylinder. The inner diameter of the protective cover is equal to the outer diameter of the rotating column, and the lowest part of the protective cover is lower than the thread at the lowest part of the rotating column; that is, the protective cover is tightly sleeved on the rotating column to prevent dust and sundries from entering, improving the adaptability and reliability of the device.

[0009] The supporting assembly includes a chassis fixedly connected to the bottom of the rotating column; that is, the circular design of the chassis helps to evenly disperse the pressure of the support on the ground and increase stability.

[0010] Through holes are formed in the middle of the chassis, and guide grooves are formed at the bottom of the rotating column. Positioning columns are slidably connected in the guide grooves; that is, through the guide grooves and the positioning columns, precise adjustment and fixation of the position of the support are achieved.

[0011] Card slots are formed at the top of the guide grooves, rectangular slots are formed at the top of the card slots, and blocks having the same shape as the rectangular slots are fixedly connected to the tops of the positioning columns; that is, the blocks cooperate with the rectangular slots to fix the positions of the positioning columns and prevent accidental rotation during the adjustment process.

[0012] Positioning cones are provided at the bottoms of the positioning columns; that is, the positioning cones are inserted into the ground to increase the friction with the ground and prevent the chassis from moving at the adjusted position.

[0013] The water spraying assembly includes a water spraying frame, and a plurality of nozzles are fixedly connected to the bottom of the water spraying frame; that is, the water spraying frame sprays water mist through the plurality of nozzles to achieve the effect of dust reduction.

[0014] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0015] 1. The user can manually rotate the threaded cylinder to move the rotating column up and down along the sliding groove, thereby adjusting the height of the support. In this way, even on uneven ground, the stability and appropriate spraying height of the water spraying assembly can be maintained by adjusting the height of the support, and the adjustable design can better adapt to different construction sites.

[0016] 2. The protective cover can be tightly sleeved on the rotating column to prevent dust, dirt or other sundries from entering the threaded part of the threaded cylinder and the rotating column, thus avoiding problems such as wear or jamming caused by the entry of impurities. In the construction site, due to the usually harsh environment, the presence of the protective cover effectively improves the reliability of the dust reduction device.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-4 , and clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0027] As Figures 1-4 shown: This embodiment provides a dust reduction device for civil engineering, including four supports 100. A same water spraying component 300 is provided at the top of the supports 100. Adjustment components 200 are provided at the bottoms of the supports 100. The adjustment component 200 includes a rotating column 201 and a threaded cylinder 202. Sliding grooves are respectively opened in the middle parts of the supports 100. The rotating columns 201 are respectively slidably connected to the middle parts of the sliding grooves. The outer diameter of the rotating column 201 is equal to the inner diameter of the sliding groove. The threaded cylinders 202 are respectively rotatably connected to the bottoms of the supports 100. Threads are respectively opened in the middle parts of the outer walls of the rotating columns 201. The threaded cylinders 202 are respectively threadedly connected to the adjacent rotating columns 201. Support components 400 are respectively provided at the bottoms of the rotating columns 201;

[0028] During use, by adjusting the adjusting component 200, the user can manually rotate the threaded cylinder 202 to move the rotating column 201 up and down along the sliding groove, thereby adjusting the height of the support 100. In this way, even on uneven ground, the stability and proper spraying height of the spraying component 300 can be maintained by adjusting the height of the support 100. The supporting component 400 is located at the bottom of the rotating column 201 and is used to enhance the stability of the support 100 and prevent the support 100 from tilting or shaking due to the unevenness of the ground during use.

[0029] The hexagonal column 203 is as Figure 1 shown.

[0030] The adjusting component 200 further includes a hexagonal column 203 fixedly connected to the middle of the threaded cylinder 202;

[0031] When it is necessary to adjust the height of the support 100, the user can use a wrench to fix the hexagonal column 203 and then rotate the threaded cylinder 202. The rotation of the threaded cylinder 202 will drive the rotating column 201 to move up and down along the sliding groove, thereby realizing the adjustment of the height of the support 100. Since a thread is provided in the middle of the outer wall of the rotating column 201 and is matched with the internal thread of the threaded cylinder 202, the movement of the rotating column 201 is stable and precise.

[0032] The protective cover 204 is as Figure 1 , 2 shown.

[0033] The adjusting component 200 further includes a protective cover 204 fixedly connected to the bottom of the threaded cylinder 202. The inner diameter of the protective cover 204 is equal to the outer diameter of the rotating column 201, and the lowest part of the protective cover 204 is lower than the thread at the lowest part of the rotating column 201;

[0034] The protective cover 204 can be tightly sleeved on the rotating column 201 to prevent dust, dirt or other sundries from entering the threaded parts of the threaded cylinder 202 and the rotating column 201, thereby avoiding problems such as wear or jamming caused by the entry of impurities. At the construction site, since the environment is usually relatively harsh, the presence of the protective cover 204 effectively improves the adaptability and reliability of the dust reduction device. It reduces the maintenance frequency, extends the service life of the equipment, and reduces the maintenance cost.

[0035] The chassis 401 is as Figure 1 , 2 , 3 shown.

[0036] The supporting component 400 includes a chassis 401 fixedly connected to the bottom of the rotating column 201. The chassis 401 is circular, and the diameter of the chassis 401 is larger than the diameter of the rotating column 201;

[0037] Its circular design helps to evenly distribute the pressure of the support 100 on the ground. Especially on uneven or soft ground, it can effectively prevent the support 100 from sinking or tilting due to uneven weight, provide a wider support area, and thus increase the stability of the entire device.

[0038] The through holes 402 are as Figure 3 shown.

[0039] Through holes 402 are provided in the middle of the chassis 401, and guide grooves 403 are provided at the bottoms of the rotating columns 201. The diameter of the guide grooves 403 is the same as that of the through holes 402. Positioning columns 404 are slidably connected in the guide grooves 403. Card slots 405 are provided at the tops of the guide grooves 403. The card slots 405 are circular, and the diameter of the card slots 405 is larger than that of the guide grooves 403. Rectangular grooves 406 are provided at the tops of the card slots 405. Clamping blocks 407 having the same shape as the rectangular grooves 406 are fixedly connected to the tops of the positioning columns 404. Positioning cones 408 are provided at the bottoms of the positioning columns 404. The wider end of the diameter of the positioning cone 408 is fixedly connected to the bottom of the positioning column 404;

[0040] When the positioning column 404 slides to the top of the guide groove 403, the clamping block 407 can be inserted into the rectangular groove 406, thereby fixing the position of the positioning column 404 and preventing the positioning column 404 from accidentally rotating during the adjustment process. After the rotating column 201 is adjusted, the positioning column 404 and the clamping block 407 are pulled out, and the clamping block 407 falls into the card slot 405. Then the positioning column 404 is rotated to displace the position of the clamping block 407 from the rectangular groove 406, so that the bottom of the positioning column 404 cannot move up and down. At this time, the positioning cone 408 is fixed, and the narrower end of the positioning cone 408 can be inserted into the soft ground, thereby increasing the friction with the ground and preventing the chassis 401 from moving at the adjusted position.

[0041] The water spraying frame 301 is as Figure 1 shown.

[0042] The water spraying assembly 300 includes a water spraying frame 301. A plurality of nozzles 302 are fixedly connected to the bottom of the water spraying frame 301. A connection port is provided on one side of the water spraying frame 301, and the connection port is used to connect to an external water source;

[0043] Open the water source through the connection port to allow water to flow into the water spraying assembly 300. At this time, the water will pass through the plurality of nozzles 302 at the bottom of the water spraying frame 301, and the nozzles 302 will spray the water into fine water mist. These water mists will evenly cover the designated area of the construction site, thereby achieving the purpose of dust reduction.

[0044] Working principle:

[0045] In use, the user fixes the hexagonal column with a wrench and rotates the threaded cylinder to adjust the height of the support. The protective cover covers the bottom of the threaded cylinder to prevent dust and debris from entering, improving the adaptability and reliability of the device. The chassis is fixed to the bottom of the rotating column, and its circular design helps to evenly disperse the pressure of the support on the ground, increasing stability. There is a through hole in the middle of the chassis and a guiding groove at the bottom of the rotating column. The positioning column can slide in the guiding groove, and there are a clamping block and a positioning cone at the top, which are used to fix the position of the support and enhance the friction with the ground.

[0046] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0047] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
