Description

Technical Field

[0001] This invention relates to the field of building dust removal technology, and in particular to a spray device for heatstroke prevention and dust removal on climbing scaffolding at building construction sites. Background Technology

[0002] With the continuous development of the construction industry, the construction of high-rise and super high-rise buildings has become increasingly common, and the control of construction safety and the construction environment has received more and more attention. Climbing scaffolds, as a temporary structure that saves construction space and improves construction efficiency, are widely used on construction sites. However, the outside of the climbing scaffolds usually requires spraying to suppress construction dust, reduce fire risks, and cool the working environment.

[0003] Traditional sprinkler systems for climbing scaffolds typically employ temporary piping and fixed sprinkler heads. This approach has several drawbacks: First, the location of sprinkler points is difficult to adjust flexibly with the construction progress, resulting in uneven sprinkler coverage and affecting dust suppression and cooling effects. Second, the installation, dismantling, and maintenance of traditional sprinkler systems are cumbersome and easily affected by steel pipes and scaffolding structures in the construction environment, making layout difficult. Third, the sprinkler heads are exposed to the construction environment for extended periods, making them susceptible to external impacts, debris blockage, and environmental corrosion, resulting in low reliability.

[0026] See Figures 1 to 11As shown, a spraying device for heatstroke prevention and dust removal on a climbing scaffold at a construction site includes: at least one set of circumferential pipes 100 arranged along the outer periphery of the climbing scaffold and fixedly installed on the climbing scaffold by a climbing scaffold fixing mechanism 110; the main pipe is mainly used to transport dust removal water source, and is arranged in a circumferential manner along the overall outline of the climbing scaffold to ensure that the dust removal water source can be evenly distributed to each spraying point. Several installation and control mechanisms 120 are arranged along the outer periphery of the building climbing frame and installed on the building climbing frame. They serve as the basis for the installation and control of the spray points. As a bridge between the spray assembly 700 and the building climbing frame, they not only provide a stable installation platform, but more importantly, they can realize flexible adjustment of the position of the spray points relative to the climbing frame to adapt to different building facade shapes or specific dust removal needs. Several spraying components 700 are installed on the control support mechanism and connected to the ring pipeline 100 via connecting hose modules. Spraying points are provided on them; they are the functional units that actually perform the spraying operation, and the spraying points, namely atomizing nozzles (750), spray water mist outwards. Through the connecting hose modules, the spraying components 700 obtain water from the ring pipeline 100 to achieve decentralized spraying.

[0027] Several protective spray components 800 are installed on the spray component 700; this is one of the core innovations of the present invention, which not only provides physical protection for the spray points to prevent clogging or damage, but also has a unique auxiliary dust reduction function. The central control mechanism 130 is located on the floor and is connected to the ring pipeline 100, the spray assembly 700 and the protective spray assembly 800. It is used to control the spraying operation. It is the "brain" of the whole device. It is responsible for receiving instructions and sending control signals to the water supply of the ring pipeline 100, the start and stop of each spray assembly 700 and the action of the protective spray assembly 800, so as to ensure that the whole system operates efficiently according to the preset program or actual needs and realizes automated heatstroke prevention and dust removal.

[0028] More preferably, the ring-shaped conduit 100 includes: Several sections of ring-shaped pipes are arranged sequentially along the outer perimeter of the building's climbing scaffolding; Several connectors are used to connect adjacent annular pipes; A delivery pipeline unit is used to connect to the central control mechanism 130; An end cap is installed at the end of the annular pipe 100; it is used to seal the end of the annular pipe 100 to prevent water leakage and ensure that the pipe forms a complete closed or semi-closed loop. The connector includes: a plurality of connecting tees, a plurality of connecting joints, and a plurality of corner connectors, wherein one passage of the connecting tee is used to connect to the connecting hose module, and the other two passages are used to connect to the adjacent circumferential pipe; the connecting joints are used to connect to the adjacent circumferential pipe; and the corner connectors are located at the corners of the circumferential pipes.

[0029] Specifically, the delivery pipeline unit is the physical channel connecting the central control mechanism 130 and the ring pipeline 100. It typically consists of one or more pipes, one end of which is connected to the outlet of the central control mechanism 130, and the other end of which is connected to the ring pipeline 100. It may use threaded connections, quick couplings, flange connections, or welding to ensure the connection is secure and airtight, preventing leakage.

[0030] In addition, considering that they are exposed to the outdoor environment for a long time, corrosion-resistant and pressure-resistant materials are usually required, such as UPVC, PE or stainless steel.

[0031] Furthermore, the connecting hose module consists of a retractable, flexible high-pressure hose. One end is connected to a connecting tee on the circumferential pipeline 100, and the other end is connected to the connecting base pipe 730 of the spray assembly 700. For easy and quick installation and disassembly, quick couplings or clamps are typically used to connect both ends of the hose. The flexibility and retractability of the connecting hose allow the spray assembly 700 to move freely horizontally and vertically under the control of the installation mechanism without causing stress or torsion to the pipeline system, ensuring a smooth water supply. The high-pressure resistance of the hose ensures the safety of the system during operation.

[0032] More preferably, the climbing frame fixing mechanism 110 includes a clamp connector disposed on the climbing frame.

[0033] More preferably, the protective netting of the building climbing scaffold has a plurality of adjustable slots, and the adjustable slots are configured one-to-one with the installation and adjustment mechanism 120, and the installation and adjustment mechanism 120 includes: The reference mounting bracket 400 is installed on the building climbing frame and serves as the mounting base for the installation and control mechanism 120; The regulating installation component 500 is installed on the reference mounting bracket 400 and is used to adjust the horizontal and vertical positions of the spray points relative to the building climbing frame, thereby changing the spacing and arrangement of the spray points. Through its internal transmission structure, it realizes the horizontal and vertical displacement of the spray component 700 relative to the building climbing frame, thereby precisely adjusting the coverage and spacing of the spray points to optimize the dust suppression effect.

[0034] The protective support assembly 600 is installed on the building climbing scaffold. It penetrates the protective netting through a regulating slot and works in conjunction with the regulating installation assembly 500 to allow the sprinkler assembly 700 to penetrate the protective netting, while also serving as a patching structure for the netting. When the sprinkler assembly 700 passes through the protective netting, it effectively fills the gap between the regulating slot and the sprinkler assembly 700, creating a tight "patch" effect. This ensures the integrity of the climbing scaffold protective netting, preventing debris or personnel from falling, while also maintaining the aesthetics of the building facade.

[0035] Furthermore, the reference mounting bracket 400 includes: The reference base 410 has several reference grooves 411, reference screws 412 that cooperate with the reference grooves 411 are provided on it, and a stable base frame 420 that cooperates with the protective bracket assembly 600 is provided on it.

Through mechanical structures such as gear meshing, they ensure that the two sets of control rotating frame units 510 can rotate synchronously and smoothly under the action of the drive unit, so that the control mounting bracket 540 can be accurately adjusted in the horizontal direction. The control drive unit 530 is disposed on the control bracket 440 and serves as the drive source for the control rotating frame unit 510; And a control mounting bracket 540 is provided between two sets of control rotating frame units 510, one end of which is connected to the control rotating frame unit 510, and the other end of which is provided with a mounting base 543 for connecting to the spray assembly 700.

[0040] Furthermore, the regulation and stabilization unit 520 includes: A stabilizing bearing 521 is mounted on the regulating bracket 440 and rotates in conjunction with the regulating shaft 511; A stabilizing gear 522 is mounted on the regulating shaft 511; And a smoothing gear set 523, which is installed on the regulating bracket 440 and meshes with the smoothing gear 522.

[0041] Specifically, the regulating and stabilizing unit 520 provides smooth rotational support through the stabilizing bearing 521, and the precise meshing of the stabilizing gear 522 and the stabilizing gear set 523 can eliminate gaps and wobbling during rotation, ensuring the accuracy and stability of the regulating and stabilizing frame unit 510 when adjusting its position.

[0042] Furthermore, the regulating mounting bracket 540 includes; Two mounting side plates 541, one end of which is provided with a mounting base plate 542 connected to the connecting base 513, and the other end of which is provided with a mounting base frame 543 connected to the spray assembly 700; The lifting mounting plate 544 has a lifting rotating groove 545 at one end, and a steering roller 546 that cooperates with the connecting hose module is provided on the lifting rotating groove 545.

The steering roller 546, located in the lifting rotating groove 545, provides guidance and support for the connecting hose module, reducing wear and tangling of the hose during the adjustment process.

[0045] Specifically, the control drive unit 530 includes components disposed at one and / or both ends of the control bracket 440, and the control drive unit 530 is configured as a simple drive motor structure, or as a differential drive unit composed of a drive motor and a differential gear; furthermore, the control drive unit 530 can also be configured as a simple transmission structure composed of sprockets / pulleys and chains / belts. Further, it provides mechanical power to drive the control rotating frame unit 510 to rotate, thereby realizing the displacement adjustment of the control mounting assembly 500.

And a guide roller unit 670, which is installed on the protective base frame 610 and cooperates with the protective through groove 660, and facilitates the adjustment of the installation component 500 through the protective through groove 660.

[0047] Furthermore, the protective support assembly 600, through the sliding of the protective slide 640 within the protective slide groove 620, ensures that the closed mesh 650 always covers the control channel when the spray assembly 700 is adjusted, thus achieving a dynamic protective mesh patching function. The guide roller unit 670 provides a smooth passage for the control installation assembly 500, reducing friction and jamming.

[0048] Furthermore, the guide roller unit 670 includes: The guide frame 671 is mounted on the protective slide 640; The guide bracket 672 is symmetrically arranged on the guide base 671 and cooperates with the protective through groove 660; And guide roller shaft 673, which is mounted on the guide bracket 672, and is provided with guide roller 674 that cooperates with the adjustment and installation assembly 500.

[0049] Preferably, the protective bracket assembly 600 further includes: The linkage drive unit 680 is installed on the protective base frame 610 and is linked and cooperates with the control and installation component 500. It also acts as the protective slide 640 to lift and lower along the protective slide groove 620. And the extrusion stabilization unit 690 is installed on the protective slide 640 and works in conjunction with the guide roller unit 670.

[0051] Preferably, the extrusion stabilization unit 690 includes a linear extrusion structure symmetrically arranged on both sides of the guide roller unit 670.
