Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a wall spraying device for building construction. Background Technology

[0002] During construction, a large amount of dust is often generated at the construction site. This dust not only pollutes the surrounding environment and affects the normal lives of nearby residents, but also poses a threat to the health of construction workers. In order to effectively control construction dust and improve the construction environment, construction site fencing spray devices have emerged. These devices are usually installed on the fence of the construction site. Water is fed into the spray pipes and nozzles set on the construction site fence through equipment such as high-pressure water pumps. The nozzles work together to atomize the water and spray it into the air. The water mist absorbs dust particles in the air, thereby achieving the purpose of dust reduction. It can form a water mist barrier around the construction area, reducing the spread of dust to the outside world.

[0003] However, in the use of existing construction site wall spraying devices, the height of the spray pipe and nozzle is mostly fixed, and it is impossible to flexibly adjust it according to the distribution height of dust at the construction site. When dust is concentrated at a higher position, the spray range of the nozzle is limited by the fixed height, and the dust suppression effect will be greatly reduced, directly affecting the dust suppression effect and the flexibility of use. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a construction site wall spraying device that has the advantages of flexibly adjusting the height of the spray pipe and nozzle to adapt to different dust distribution heights, improving dust suppression effect and usage flexibility. This improves or solves, to a certain extent, the problems of existing construction site wall spraying devices where the height of the spray pipe and nozzle is mostly fixed during use, making it impossible to flexibly adjust according to the dust distribution height at the construction site. When dust is concentrated at a higher position, the spray range of the nozzle is limited by the fixed height, significantly reducing the dust suppression effect and directly impacting usage flexibility.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Example 1

[0025] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a construction fence spraying device, including a fence 1 and a fence panel 2. The fence panel 2 is set inside the fence 1 and fixedly connected to the fence 1. Movable grooves 3 are respectively opened on the left and right sides of the fence 1, and a placement groove 4 is opened at the lower end of the fence 1. The left and right ends of the placement groove 4 are respectively connected to the lower ends of the two movable grooves 3. Lifting components 5 are evenly arranged inside the two movable grooves 3. A driving component 6 is arranged inside the placement groove 4. A spraying component 7 is arranged on the front side of the upper end of the fence 1.

[0026] Specifically, the wall spraying device has the advantage of being able to flexibly adjust the height of the spray component 7 according to the dust distribution height at the construction site, thereby improving the targeting and overall effect of dust suppression.

[0027] Furthermore, the driving component 6 drives the lifting assembly 5 to operate within the movable slot 3, thereby enabling the spray assembly 7 to adjust its height. Simultaneously, the spray assembly 7 is connected to the water supply system via the connecting conveying hose 8 to complete the spray dust suppression. All components work together to achieve flexible and efficient dust suppression.

[0028] Example 2

[0029] In the second embodiment of this utility model, the lifting assembly 5 includes a screw 51, a movable support rod 52, and a worm gear 53. The screw 51 is disposed inside the movable groove 3, and its lower end is rotatably connected to the bottom surface inside the movable groove 3. The movable support rod 52 is disposed inside the upper end of the movable groove 3, and is sleeved on the surface of the screw 51 and threadedly connected to the screw 51. The upper end of the movable support rod 52 extends out of the movable groove 3 and is slidably connected to the movable groove 3. The worm gear 53 is sleeved on the lower end surface of the screw 51 and is fixedly connected to the screw 51.

[0030] The worm gears 53 on the left and right sides correspond to the mounting slots 4 and are adapted to the drive component 6;

[0031] The driving component 6 includes a worm gear 61 and a crank handle 62. The worm gear 61 is located inside the mounting groove 4, and its left and right ends extend into the two movable grooves 3 respectively, and are rotatably connected to the railing 1. The left and right ends of the worm gear 61 are respectively engaged with two worm wheels 53, and the left end extends out of the railing 1. The crank handle 62 is fixedly connected to the left end of the worm gear 61.

[0032] Specifically, by setting up the lifting component 5 and the driving component 6, the height of the spray component 7 can be stably adjusted, ensuring that it can accurately adapt to dust distribution areas at different heights and improving the flexibility of the device.

[0033] Furthermore, during height adjustment, the operator rotates the crank handle 62 in the drive unit 6, causing the worm 61 to rotate within the mounting groove 4. Since the worm 61 meshes with the worm wheels 53 at the lower ends of the left and right screws 51, the rotation of the worm 61 will synchronously drive the worm wheels 53 and the screws 51 to rotate. At this time, the movable support rod 52, which is threadedly connected to the screw 51, slides up and down along the movable groove 3 under the rotation of the screw 51, thereby driving the spray assembly 7, which is fixedly connected to the top via the support seat 72, to rise and fall as a whole.

[0034] Example 3

[0035] In the third embodiment of this utility model, the spray assembly 7 includes a spray pipe 71, a support base 72, and a nozzle 73. The spray pipe 71 is disposed on the front side of the upper end of two movable support rods 52. There are two support bases 72, which are respectively sleeved on the left and right end surfaces of the spray pipe 71 and fixedly connected to the spray pipe 71. The rear sides of the two support bases 72 are respectively fixedly connected to the front side of the upper end of the two movable support rods 52. There are several nozzles 73, which are evenly sleeved on the surface of the spray pipe 71 and fixedly connected to the spray pipe 71, and are interconnected.

[0036] The left and right ends of the spray pipe 71 are respectively fixedly connected to the connecting delivery hose 8 by threads.

[0037] Specifically, by setting up the spray component 7, a uniform and wide-ranging water mist coverage can be formed. Combined with the connecting delivery hose 8, multiple devices can be connected in series to improve the overall dust reduction efficiency and coverage integrity of the construction area.

[0038] Furthermore, during use, one end of the connecting conveying hose 8 is fixedly connected to the spray pipe 71 via threads, while the other end can be connected to the water supply system at the construction site, and used to connect multiple spray devices in series to form a continuous spray barrier. When the water supply system is started, the water flow will be transported to the inside of the spray pipe 71 through the connecting conveying hose 8. Since the spray pipe 71 is interconnected with several evenly distributed nozzles 73, the water flow will enter each nozzle 73 under pressure. After being atomized by the nozzles 73, it forms a fine water mist, which is finally sprayed out from the nozzles 73 to achieve dust suppression around the construction area. The connecting conveying hose 8, which is connected to both ends of the spray pipe 71 via threads, flexibly adjusts its shape according to the height of the spray pipe 71, naturally extending when rising and bending moderately when descending, always maintaining a stable connection with the water supply system.

[0039] Working principle:

[0040] During use, one end of the connecting conveying hose 8 is fixedly connected to the spray pipe 71 by a thread, while the other end can be connected to the water supply system at the construction site and used to connect multiple spray devices in series to form a continuous spray barrier. When the water supply system is started, the water flow will be transported to the inside of the spray pipe 71 through the connecting conveying hose 8. Since the spray pipe 71 is interconnected with several evenly distributed nozzles 73, the water flow will enter each nozzle 73 under pressure. After being atomized by the nozzles 73, it will form a fine water mist, which will finally be sprayed out from the nozzles 73 to achieve dust suppression around the construction area.

[0041] Meanwhile, the connecting delivery hose 8 is flexible and can flexibly extend or bend when the spray assembly 7 is adjusted in height with the lifting assembly 5. The continuous water supply will not be affected by the change in the position of the spray pipe 71, ensuring that the spray dust suppression process is stable.

[0042] During height adjustment, the operator rotates the crank 62 in the drive unit 6, causing the worm 61 to rotate within the mounting groove 4. Since the worm 61 meshes with the worm wheels 53 at the lower ends of the left and right screws 51, the rotation of the worm 61 synchronously drives the worm wheels 53 and the screws 51 to rotate. At this time, the movable support rod 52, which is threaded to the screw 51, slides up and down along the movable groove 3 under the action of the rotation of the screw 51, thereby driving the spray assembly 7, which is fixedly connected to the top via the support seat 72, to rise and fall as a whole. During this process, the connecting delivery hose 8, which is threaded to both ends of the spray pipe 71, flexibly adjusts its shape according to the height change of the spray pipe 71, naturally extending when rising and bending moderately when descending, always maintaining a stable connection with the water supply system, thus adapting to the dust suppression needs of different dust distribution heights.

[0043] In summary, by using the combined components of the frame 1, enclosure 2, movable groove 3, placement groove 4, lifting assembly 5, screw 51, movable support rod 52, worm gear 53, drive component 6, worm 61, crank handle 62, spray assembly 7, spray pipe 71, support base 72, nozzle 73, and connecting conveying hose 8, the height of the spray pipe and nozzle can be flexibly adjusted to adapt to different dust distribution heights, thereby improving dust suppression effect and operational flexibility.
