Description

Technical Field

[0001] This utility model relates to the field of dust suppression technology, specifically to a dust suppression device for buildings. Background Technology

[0002] During construction, operations such as earthwork excavation, material handling, and concrete mixing generate a large amount of dust. This dust not only severely pollutes the air quality at the construction site, endangering the health of construction workers and causing respiratory diseases, but also has adverse effects on the surrounding environment, such as reducing visibility, disrupting traffic, and polluting the living environment of nearby residents. Traditional methods for dust suppression in construction mainly include water truck spraying and manual spraying. However, water truck spraying has a limited coverage area. Construction sites typically have various building materials piled up, construction equipment parked, and obstacles and uneven ground formed by different construction stages, making it difficult to cover the entire construction site. In addition, it consumes a large amount of water and can easily cause water accumulation on the site. Manual spraying is inefficient, with uneven spraying, and cannot effectively control dust concentration for a long time.

[0003] Therefore, there is an urgent need for a building dust suppression device to improve the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to provide a building dust suppression device to solve the problems mentioned in the background art.

[0006] As a further improvement to this technical solution, a caster wheel is fixedly connected to the lower surface of the base, and a stop block is fixedly connected to the upper surface of the base. The stop block is used to limit the position of the spraying rod. A through hole is provided on the upper surface of the base, and a spring is fixedly connected inside the through hole. A movable column is fixedly connected to the upper surface of the spring. The movable column is used to limit the position of the spraying assembly after it is folded and to limit the position on the other side away from the stop block after it is unfolded. A fixed seat is fixedly connected to one side of the upper surface of the base, and a push rod is fixedly connected to the upper surface of the fixed seat.

[0007] As a further improvement to this technical solution, a conduit is fixedly connected to the surface of the spray rod one, the other end of the conduit one is connected to the water outlet assembly, a conduit two is fixedly connected to the other end of the spray rod one, and the other end of the conduit two is fixedly connected to the spray rod two.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] The foldable spray boom of this dust suppression device enhances its spatial adaptability. In narrow construction sites or building interiors, the spray boom can be folded to reduce the overall lateral dimensions, allowing the trolley to pass through narrow passages or doorways. Upon reaching the dust suppression area, the spray boom can be unfolded to restore the normal spray range. This flexible spatial adaptability allows the device to function effectively in construction sites with various spatial conditions, improving its versatility. The trolley can be pushed to specific dust suppression locations, allowing operators to precisely target the dust source based on actual dust generation conditions, such as ongoing excavation, concrete mixing, or material loading / unloading. Compared to large-area, indiscriminate spraying, this precise positioning more effectively controls the spread of dust in localized high-concentration areas, improving dust suppression efficiency, reducing water waste, and making dust suppression operations more targeted and effective.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, this embodiment provides a building dust suppression device, including a movable component 1. The movable component 1 includes a base 10, with a limiting post 15 fixedly connected to the upper surface of the base 10. A spring 16 is sleeved on the surface of the limiting post 15, and a base plate 17 is slidably connected to the surface of the limiting post 15. A spraying component 2 is fixedly connected to the upper surface of the base 10. The spraying component 2 includes a spraying rod 20, with a fixed rod 21 rotatably connected to one end of the spraying rod 20. The fixed rod 21 is fixedly connected to the upper surface of the base 10. A nozzle 23 is provided on the lower surface of the spraying rod 20. A water cavity is provided inside the spraying rod 20, and the nozzle 23 communicates with the water cavity. A hinge 26 is fixedly connected to one end of the spraying rod 20, and a spraying rod 28 is fixedly connected to the other end of the hinge 26. The spraying rod 20 and the spraying rod 28 are rotatably connected. A water storage component 3 is fixedly connected to the upper surface of the base plate 17.

[0022] The working principle described above is as follows: First, the base 10 serves as the basic support structure. The limiting post 15 above it and the spring 16 sleeved on the limiting post 15 work together to support the slidingly connected base plate 17. When the device encounters bumps or vibrations during movement, the base plate 17 can slide up and down along the limiting post 15. The spring 16 acts as a buffer to reduce the impact of vibration on the water storage component 3 and the entire device, ensuring the stability of the device operation. The spraying assembly 2 on the base 10 is a key part of dust suppression. Water enters the water chamber of the spraying rod 20 through the water storage assembly 3, and then is sprayed out from the nozzle 23 on the lower surface to form a water mist. The spraying rod 20 is rotatably connected to the fixed rod 21 at one end, and its angle can be adjusted within a certain range to adapt to the dust suppression needs in different directions. The spraying rod 20 and the spraying rod 28 are rotatably connected by the hinge 26, so that the spraying rod 28 can rotate relative to the spraying rod 20. This foldable and rotatable design makes it convenient to fold up the spraying rod 28 when not in use to reduce space occupation, and unfold the spraying rod 28 when it is necessary to expand the spraying range. Through the coordinated cooperation of various components, effective dust suppression operations can be achieved in the construction area.

[0023] To facilitate movement on construction sites, in this embodiment, a caster wheel 11 is fixedly connected to the lower surface of the base 10, and a stop block 14 is fixedly connected to the upper surface of the base 10. The stop block 14 is used to limit the position of the spraying rod 20. A through hole is provided on the upper surface of the base 10, and a spring 12 is fixedly connected inside the through hole. A movable column 13 is fixedly connected to the upper surface of the spring 12. The movable column 13 is used to limit the position of the spraying assembly 2 after it is folded, and to limit the position on the other side away from the stop block 14 after it is unfolded. A fixed seat 18 is fixedly connected to one side of the upper surface of the base 10, and a push rod 19 is fixedly connected to the upper surface of the fixed seat 18. The caster wheel 11 fixedly connected to the lower surface of the base 10 enables the entire device to move flexibly, allowing it to easily move through the complex and varied terrain of the construction site and freely travel to different construction areas for dust suppression operations. The stop block 14 on the surface plays a crucial limiting role. When the spray rod 20 rotates to adjust its angle, the stop block 14 can prevent it from rotating excessively, ensuring that the spray rod 20 is in a suitable working position and ensuring the accuracy of the spray direction during dust suppression. The combination of the spring 12 and the movable column 13 in the through hole on the upper surface of the base 10 is also very important. After the spray assembly 2 is folded up, the movable column 13 can be locked in the corresponding position of the spray assembly 2 under the action of the spring 12, keeping it in the folded state. When the spray assembly 2 is unfolded, the movable column 13 can also abut against the other side of the spray rod 20 away from the stop block 14, limiting its excessive rotation in the opposite direction, ensuring that the spray rod 20 is stably in the appropriate unfolded position, which is convenient for dust suppression spraying operations. The push rod 19 on the upper surface of the fixed base 18 provides the operator with a part that makes it easy to apply force to push the device, making it convenient to move the device in various places on the construction site.

[0024] To effectively spray the city, the spray boom is folded to the appropriate size for actual use. Therefore, in this implementation, a conduit 22 is fixedly connected to the surface of spray boom 20, with its other end connected to the water outlet assembly. A second conduit 27 is fixedly connected to the other end of spray boom 20, and its other end is fixedly connected to spray boom 28. Both spray boom 20 and spray boom 28 have a sliding groove 24 on one side, with a fixed slider 25 slidably connected to the groove. The fixed slider 25 is used to fix spray boom 20 and spray boom 28. A hanging ring 29 is fixedly connected to the upper surface of spray boom 28. The conduit 22 on the surface of spray boom 20 is responsible for introducing water from the water outlet assembly into the water chamber inside spray boom 20, thereby providing a water source for the nozzle 23 to achieve dust suppression spraying. When it is necessary to expand the spraying range, spray boom 28 can be folded... Sprayer rod 28 rotates and unfolds around the hinge 26 connecting it to sprayer rod 20. At this time, the conduit 27 at the other end of sprayer rod 20 connects the water chamber to sprayer rod 28, ensuring that water can be delivered to sprayer rod 28 so that the nozzle 23 on it can spray water normally for dust suppression. The cooperation of the sliding groove 24 and the fixed slider 25 on one side of sprayer rod 20 and sprayer rod 28 is the key design for fixing their relative positions. When sprayer rod 28 is rotated to a suitable angle, the fixed slider 25 is slid to lock it in the corresponding position, so that sprayer rod 20 and sprayer rod 28 can be kept fixed and stably maintained in the unfolded state for large-area dust suppression. When it is necessary to fold it up, the fixed slider 25 is slid in the opposite direction to release the fixation, so that sprayer rod 28 can be folded up to reduce space occupation. The hanging ring 29 on the upper surface of the spray bar 28 can be used to attach the cable 34, further assisting in fixing and limiting the position of the spray bar 28, and making it convenient to flexibly adjust the shape of the spray bar according to actual usage needs.

[0025] To store water, in this embodiment, the water storage component 3 includes a water tank 30, which is fixedly connected to the upper surface of the base plate 17. A cable 34 is fixedly connected to one side of the water tank 30 for holding the spray bar 28. One end of the cable 34 is hooked to a hanging ring 29. A dust cover 31 is fixedly connected to the upper surface of the water tank 30, and an air pump 32 is fixedly connected inside the dust cover 31 for pressurizing the water tank 30. A water inlet 35 is provided on the upper surface of the water tank 30. A cover plate 36 is rotatably connected to the water inlet 35, and a water level gauge 33 is fixedly connected to one side of the water tank 30. Water can be added to the water tank 30 through the water inlet 35. The rotatably connected cover plate 36 can cover the water inlet 35 under normal circumstances to prevent dust, debris, etc. from entering the water tank 30 and affecting the water quality, and to prevent accidental water overflow. The water level gauge 33 fixedly connected to one side of the water tank 30 can intuitively display the water level in the water tank 30, so that the operator can know the water level in time and add water in time when the water is low. During dust suppression operation, the air pump 32 inside the dust cover 31 works. The air pump 32 pressurizes the inside of the water tank 30, so that the water in the water tank 30 can flow more smoothly through the first conduit 22 and the second conduit 27 to the water chamber of the first spray bar 20 and the second spray bar 28, and then be sprayed out from the nozzle 23 to form water mist for dust suppression. One end of the cable 34 on one side of the water tank 30 is attached to the hanging ring 29 of the spray bar 28. The cable 34 can pull the spray bar 28 to a certain extent, helping to maintain the position of the spray bar 28. Especially when the device moves or under some special circumstances, it prevents the spray bar 28 from swinging randomly, ensuring the stability of the entire device structure and the normal operation of dust suppression.

[0026] In this embodiment, a dust suppression device for construction is used in practice. First, the base 10 serves as the basic support structure. The casters 11 fixedly connected to the lower surface of the base 10 enable the entire device to move flexibly, allowing it to easily navigate the complex and varied terrain of construction sites and freely travel to different construction areas for dust suppression operations. Water can be added to the water tank 30 through the water inlet 35. The rotating cover 36 can cover the water inlet 35 under normal circumstances to prevent dust, debris, etc. from entering the water tank 30 and affecting the water quality, as well as to prevent accidental water overflow. The water level gauge 33 fixedly connected to one side of the water tank 30 can intuitively display the water level in the water tank 30, making it convenient for operators to understand the water level in a timely manner so that water can be added in time when it is insufficient. During dust suppression operations, the air pump 32 inside the dust cover 31 operates, pressurizing the water tank 30 so that the water in the water tank 30 can flow more smoothly through the first conduit 22 and the second conduit 27 to the water chambers of the first spray bar 20 and the second spray bar 28, and then be sprayed out from the nozzle 23 to form water mist for dust suppression. One end of the cable 34 on one side of the water tank 30 is attached to the hanging ring 29 of the second spray bar 28. The cable 34 can pull the second spray bar 28 to a certain extent, helping to maintain the position of the second spray bar 28, especially when the device moves or under some special circumstances, to prevent the second spray bar 28 from swinging randomly, ensuring the stability of the entire device structure and the normal operation of dust suppression. The guide tube 22 on the surface of the first spray bar 20 is responsible for introducing water from the water outlet component into the water chamber inside the first spray bar 20, thereby providing a water source for the nozzle 23 to achieve dust suppression spraying. When it is necessary to expand the spraying range, the second spray bar 28 can be rotated and unfolded around the hinge 26 connected to the first spray bar 20. At this time, the other end of the second spray bar 20 can be unfolded. The conduit 27 at one end connects the water chamber to the spray bar 28, ensuring that water can be delivered to the spray bar 28 so that the nozzles 23 can spray water normally for dust suppression. The cooperation of the sliding groove 24 and the fixing slider 25 on one side of the spray bar 20 and the spray bar 28 is a key design for fixing their relative positions. When the spray bar 28 is rotated to a suitable angle, the fixing slider 25 is slid to lock it in the corresponding position, keeping the spray bar 20 and the spray bar 28 fixed and stably maintaining the unfolded state for large-area dust suppression. When it needs to be folded up, the fixing slider 25 is slid in the opposite direction to release the fixation, allowing the spray bar 28 to be folded up, reducing space occupation. The hanging ring 29 on the upper surface of the spray bar 28 can be used to attach the cable 34, further assisting in fixing and restricting the position of the spray bar 28, and facilitating flexible adjustment of the shape of the spray bar according to actual use needs.
