[0025] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] This application provides a dust suppression spraying system for aerial work platforms. The dust suppression spraying system includes two types: single-column and double-column. The single-column type is suitable for operations in confined spaces. Its spraying system is deployed on a single side of the protective netting 1 of the platform, and the spraying system has no branch spraying pipes. See [link to relevant documentation]. Figure 1 The aforementioned double-column type is suitable for large-span operations, and its sprinkler system has multiple sprinkler branch pipes, see [link / reference]. Figure 2 .

[0027] The basic structure of the spray dust suppression system for aerial work platforms specifically includes:

[0028] A high-altitude sprinkler support platform, wherein the high-altitude sprinkler support platform is located within the equipment support area of ​​the electric construction platform, and the high-altitude sprinkler support platform further includes:

[0029] Platform beam 8; scaffold plank 9, the scaffold plank 9 is laid on top of the platform beam 8, and the water supply system 3 is set on the scaffold plank 9.

[0030] The high-altitude spraying support platform is a dedicated area for supporting the spraying dust suppression system equipment, and the high-altitude spraying support platform is located in the equipment support area of ​​the electric construction platform, so that the entire spraying dust suppression system can be raised and lowered with the electric construction platform.

[0031] The high-altitude spraying support platform is composed of platform beam 8 (as a load-bearing frame) and scaffold boards 9 laid on top of platform beam 8 (forming an equipment installation plane). Its core function is to provide a stable support plane for water storage tank 31.

[0032] The protective enclosure system includes a protective net 1 and a protective riser 2, which are vertically fixed to the outside of the high-altitude sprinkler support platform via the protective riser 2.

[0033] Specifically, the protective enclosure system consists of a protective net 1 and a protective riser 2. As a safety protection structure, the protective net 1 serves as a vertical barrier installed on the outer edge of the high-altitude sprinkler platform. Its mesh structure ensures safety during high-altitude operations while directly supporting the installation and positioning of the high-pressure sprinkler heads 55. The protective riser 2 serves as the rigid support frame for the protective net 1. The protective enclosure system is vertically connected to the outer edge of the high-altitude sprinkler platform via the protective riser 2, forming a stable spatial right-angle support system.

[0034] Water supply system 3 is installed on the high-altitude spray support platform, and the outlet of the water supply system 3 is connected to a guide hose 4.

[0035] The water supply system 3 also includes:

[0036] A water storage tank 31 is placed on the surface of the scaffold board 9; a submersible pump 32 has its outlet connected to the flow guide hose 4 and is built into the water storage tank 31; and a pre-filter 33 has its outlet connected to the inlet of the submersible pump 32 and is built into the water storage tank 31.

[0037] Specifically, the water supply system 3 is integrated onto the bearing surface of the scaffold plank 9 of the high-altitude sprinkler platform, and its core consists of a water storage tank 31, a submersible pump 32, and a pre-filter 33. The water storage tank 31, as a water storage container, is directly placed on the surface of the scaffold plank 9, forming the water source foundation of the water supply system 3; the pre-filter 33 and the submersible pump 32 are integrated and installed inside the water storage tank 31.

[0038] The pre-filter 33 is used to purify the water entering the spray system. Its outlet is connected to the inlet of the submersible pump 32 through a sealing connector to form a filtration channel. The submersible pump 32 is responsible for pressurizing and delivering water. Its outlet extends to the outside of the tank and is tightly connected to the guide hose 4.

[0039] The integrated design of the water supply system 3 creates a closed loop for the water flow path: external water source input into the water storage tank 31 → pre-filter 33 purification → submersible pump 32 pressurization → flow guide hose 4 output, ensuring water quality cleanliness while achieving high-pressure water delivery, providing a stable water supply to the spray pipe 5.

[0040] The water storage tank 31 also includes:

[0041] An automatic water level control valve 34 is installed on the inner wall of the water storage tank 31; wherein, the automatic water level control valve 34 is used to mechanically block the water path to stop spraying when the water level in the tank is insufficient, and to automatically close the valve to stop water replenishment when the water level in the tank reaches the standard.

[0042] Specifically, the automatic water level control valve 34 built into the water storage tank 31 monitors the water volume in real time. When the water level is insufficient, it automatically blocks the water path to ensure the safety of the water supply system 3. When the water level reaches the standard, it mechanically closes the valve to prevent overflow. The entire process requires no external intervention.

[0043] Sprinkler pipe 5, which is connected to the upper end of the water supply system 3 via the guide hose 4, further includes:

[0044] Ball valve 51, the inlet of which is connected to the submersible pump 32 via the flow guide hose 4;

[0045] PE main pipeline 52, the inlet end of which is connected to the ball valve 51;

[0046] T-shaped pipe 53, the inlet of which is connected to the outlet of the PE main pipe 52;

[0047] PE branch pipe 54, ≥2 PE branch pipes 54, the inlet ends of the two PE branch pipes 54 are respectively connected to the two outlets of the tee pipe 53, and the outlet ends of the PE branch pipes 54 are connected to the high-pressure nozzle 55, which is adjustable for both spraying and water spraying modes.

[0048] Specifically, the spray pipeline 5 starts from the ball valve 51. The inlet of the ball valve 51 is sealed to the outlet of the submersible pump 32 through the guide hose 4, forming a control node for the water flow. The outlet of the ball valve 51 is directly connected to the inlet of the rigid main pipeline made of PE material, forming a stable water supply channel. Its pipe diameter is designed to match the output pressure of the water pump to ensure uniform water flow.

[0049] For the two-column platform operation, the structure of the spray dust suppression system for the aerial work platform is described below. Figure 2 Specifically, the PE main pipe 52 is connected to the inlet of the tee pipe 53. Through the physical water-dividing effect of the tee structure, the single water flow is split into two independent transport paths, realizing the directional distribution of water flow.

[0050] Two PE branch pipes 54 are respectively connected to the two water outlet ports of the tee. The pipe body is laid along the outer extension of the protective net 1 riser. A high-pressure nozzle 55 is installed at the end of each branch pipe. The water flow is converted into a fine water mist through the internal atomization structure of the nozzle to cover the dusty area of ​​the work surface.

[0051] The three-way branching design in this embodiment enables the two branch pipelines to form a symmetrical water supply network, supporting balanced coverage of the double-sided spraying under the condition of a double-column platform.

[0052] For single-column platform operation, the structure of the spray dust suppression system for aerial work platforms is described below. Figure 1 The PE main pipeline 52 of the sprinkler system extends to connect to a PE branch pipeline 54.

[0053] Mounting bracket 6, through which the spray pipe 5 is fixed to the protective riser 2; mounting bracket 6 further includes:

[0054] Fastener 61; L-shaped bracket 62, the vertical section of the L-shaped bracket 62 is inserted into the hollow cavity of the protective riser 2, and the horizontal section of the L-shaped bracket 62 is fixed to the spray pipe 5 by the fastener 61.

[0055] Specifically, the mounting bracket 6 achieves rigid fixation of the spray pipe 5 on the protective riser 2 through structural innovation, and its core is composed of an L-shaped bracket 62 and a fastener 61 working together.

[0056] The vertical section of the L-shaped bracket 62 is inserted into the hollow cavity of the protective riser 2 by plugging it in, and the inner wall of the riser forms a circumferential constraint to ensure the anti-displacement stability of the bracket under the vibration of the platform lifting and lowering; the horizontal section extends to the outside of the cavity to provide a cantilever support plane for the spray pipeline 5.

[0057] Fastener 61 presses and locks the spray pipe 5 onto the surface of the horizontal section, forming a multi-point force system: the friction between the vertical section and the inner wall of the riser resists longitudinal slippage, the horizontal section bears the weight of the pipe, and fastener 61 provides radial clamping force. The three together eliminate the risk of pipe swaying.

[0058] The installation method of the spray pipe 5 in this embodiment directly utilizes the existing structural space of the protective riser 2, without the need for welding or drilling that would damage the strength of the riser.

[0059] An intelligent electrical control system 7 is electrically connected to the water supply system 3 and is used for spray control and overload protection of the water supply system 3. The intelligent electrical control system 7 supports manual mode switching and automatic mode switching. The intelligent electrical control system 7 is used to adjust the spray duration and spray interval.

[0060] Specifically, in this embodiment, the intelligent electronic control system 7 communicates with the submersible pump 32 of the water supply system 3 via electrical circuits, and undertakes the core control tasks of starting and stopping the sprinkler and regulating the operation mode.

[0061] The intelligent electronic control system 7 has a built-in digital chip that directly drives the submersible pump 32 to switch on and off via a relay module, forming a precise closed-loop control of the water flow path. In manual mode, it supports instant start and stop operations to meet sudden dust suppression needs. In automatic mode, the spray duration and intermittent cycle can be programmed to achieve timed cyclic operation, such as setting an energy-saving operation strategy of pausing for 5 minutes after spraying for 2 minutes.

[0062] The intelligent electrical control system 7 monitors the operating current of the submersible pump 32 in real time. When it detects overload, no-load, phase loss or low voltage abnormal conditions, it immediately triggers the protection mechanism to cut off the power supply to avoid equipment damage.

[0063] The mode switching function of the intelligent electronic control system 7 is realized through physical buttons or knobs, and the spraying time parameters are set through a digital interface to ensure that the dust suppression task can still be stably performed under unattended conditions.

[0064] The overall operation of the spray dust suppression system is as follows:

[0065] After water is delivered to the water storage tank 31, the automatic water level valve closes the water supply channel when the water level reaches the target. After the intelligent electronic control system 7 is activated, the water flows through the pre-filter 33 for purification, is pressurized by the submersible pump 32, and flows sequentially through the guide hose 4, ball valve 51, PE main pipeline 52, three-way water distributor, and branch pipelines. Finally, it is atomized into particles with near-zero surface tension by the high-pressure nozzle 55, effectively adsorbing and settling hydrophilic dust. The spray dust suppression system is compatible with single-column and double-column electric construction platforms. Through the three-way branching, it can achieve single-sided series or double-sided symmetrical spray layouts. In high-temperature weather, it can also improve the working environment by absorbing heat through water mist.

[0066] Meanwhile, it should be understood that the high-altitude sprinkler bearing platform refers to the equipment bearing area on the electric construction platform consisting of platform beams 8 and scaffold boards 9, which is used to fix the water storage tank 31 of the water supply system 3. Therefore, the entire sprinkler dust suppression system can be raised and lowered with the work platform (electric construction platform).

[0067] The dust suppression spray system for aerial work platforms provided in this embodiment achieves the following technical effects:

[0068] Firstly, the dust suppression spray system of the aerial work platform can be raised and lowered with the work platform (electric construction platform), resulting in low investment cost, low operation and maintenance cost, and wide spray coverage.

[0069] Secondly, the spray system of the aerial work platform is relatively close to the demolition work surface, resulting in a better dust suppression effect.

[0070] Thirdly, the spray dust suppression system of the aerial work platform can absorb heat and reduce the temperature at the construction site in hot weather, thus improving the working environment for workers.

[0071] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
