[0002] With the acceleration of urban renewal, the risks of hollow and peeling exterior walls in existing buildings are becoming increasingly prominent, leading to a surge in demand for exterior wall decoration layer replacement. Current construction methods often employ scaffolding, suspended platforms, or "spider-man" work, involving the pulverization and removal of the plaster and decorative layers. This process generates flying debris and large amounts of dust, posing risks of falling objects causing injury or death, damage to buildings and vehicles, and safety hazards for workers operating at heights. Furthermore, traditional methods result in severe dust pollution, inefficient construction waste collection, long construction cycles, and significant waste of human and equipment resources, failing to meet the demands for safe, environmentally friendly, and efficient construction.

[0003] Therefore, improving the safety of removing exterior wall decoration layers and achieving safe collection of construction waste and effective dust control are urgent technical problems that need to be solved. Summary of the Invention

Detailed Implementation

[0033] To illustrate the technical solutions of the invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the invention and not to limit the scope of the invention.

[0034] The dust-free cleaning system for exterior wall decorative layers provided by this invention, such as Figures 1 to 6 As shown, it includes a housing 100, a material identification system 200, a cleaning system 300, an automatic limit system 400, a sealing and collecting system 500, a stabilizing system 600, and a control system (not shown). Specifically, in use, the housing 100 is first suspended to the wall area to be cleaned.

[0035] The material identification system 200 is used to identify the three-dimensional shape of the wall surface and calculate the thickness of the exterior wall decorative layer, using this data as the basis for the subsequent cleaning system 300.

[0036] The cleaning system 300 includes an outer cutting device 310 and an inner planing device 320, a scraping device 330, a vibrating cutting device 340, a crushing device 350, and a telescopic mechanism 360. The cutting device 310 cuts the area to be cleaned to form a working area. The planing device 320, scraping device 330, and vibrating cutting device 340 sequentially process the wall decoration layer from top to bottom. Specifically, the planing device 320 uses a double-row horizontally arranged roller device with blades to cut and peel the flexible material, and compress it into the dust collection hopper 520. The scraping device... The blade of device 330 is tilted downwards to remove the remaining plaster from the wall. The vibrating cutting device 340 uses a high-frequency vibrating blade to tamp the wall surface, causing it to detach from the wall. The crushing device 350 breaks up the detached plaster and other debris. The telescopic mechanism 360 uses a hydraulic drive rod 361 to drive the planing device 320, the scraping device 330, and the cutting device 310 to extend and retract slightly, so that the corresponding devices fit against the wall surface. In addition, an air inlet is provided on the upper part of the cleaning system 300 to better cool the cleaning system 300, avoid damage to the components due to high temperature, and ensure the rapid falling of plaster and other debris.

[0037] The automatic limiting system 400 is set around the cleaning system 300 and automatically adjusts the construction distance between the cleaning system 300 and the wall according to the data of the material identification system 200, thereby limiting the processing depth of the cleaning system 300 and ensuring the controllability of each layer of cleaning.

[0038] The sealed material collection system 500 includes a sealing baffle 510, a dust collection hopper 520, a material collection pipe 530, and a collection box 540. The sealing baffle 510 is disposed on the side of the cleaning system 300, and the dust collection hopper 520 is disposed at the bottom of the cleaning system 300 and connected to the sealing baffle 510. One end of the material collection pipe 530 is sealed to the dust collection hopper 520 through a sealing ring 521, and the other end is connected to the collection box 540. The stripped waste material is collected by the dust collection hopper 520 and transported to the collection box 540 on the ground through the material collection pipe 530.

[0039] The stabilization system 600 includes multiple sets of fan blades, which are disposed on the cleaning system 300 to form an air inlet and provide negative air pressure. On the one hand, the stabilization system 600 can form an air inlet cooling device and assist debris to fall, and on the other hand, it can provide negative pressure to counteract the reaction force of construction.

[0040] The control system includes a power system, a PLC controller, and a wireless signal module. The power system provides power to each system. The PLC controller adjusts the rotation speed and vibration frequency of each blade of the cutting device 310, the negative pressure intensity provided by the fan blades, and the extension stroke of the telescopic mechanism 360 in real time. The wireless signal module receives signals from a wireless remote control. The PLC controller adjusts the parameters of each device in real time throughout the process, and the wireless signal module receives remote control commands to achieve remote control.

[0041] This invention eliminates the need for a high-altitude work platform, completely avoiding the risk of operators falling from heights and improving construction safety. The sealing aggregate system 500 and the stabilizing system 600 work together to suppress dust and significantly reduce pollution to the surrounding environment. The automated and coordinated operation of each system improves construction efficiency.

[0042] In some embodiments, the material identification system 200 includes a 3D line laser imaging module, a fully automatic drilling device, a stress sensing device, and a displacement sensing and hole depth calculation module. The 3D line laser imaging module acquires three-dimensional point cloud data of the wall through line-by-line scanning and calculates the flatness. The fully automatic drilling device, in conjunction with the stress sensing device and the displacement sensing and hole depth calculation module, calculates the thickness of the exterior wall decorative layer. Specifically, the 3D line laser imaging module emits line lasers in a line-by-line scanning manner, captures three-dimensional point cloud data of the wall using the principle of laser triangulation, and converts it into spatial coordinate information. The system processes the continuously acquired point cloud data to calculate the wall flatness, providing basic parameters for subsequent cleaning operations. After receiving the start command, the fully automatic drilling device drives the drill bit to drill holes in the wall at a preset rate. The stress sensing device monitors the stress signal fed back from the wall in real time. The displacement sensing and hole depth calculation module converts the linear displacement of the drill into an electrical signal, accurately capturing changes in the drill bit position. Combined with the signal feedback from the stress sensing device, the precise thickness of the exterior wall decorative layer is calculated, providing data support for the cleaning system 300 to adjust operating parameters.

[0043] In some embodiments, the 3D line laser imaging module segments continuously acquired 3D point cloud data into a single complete 3D image frame, using a standard length of 1.5m. An internal algorithm analyzes the point cloud coordinate deviation in the single-frame image and quantifies the wall flatness to obtain a specific numerical value. The system calls a preset compliance judgment standard to automatically determine the flatness of the current measurement area. If the judgment result is out of bounds, the system automatically triggers a subsequent refined calculation process to provide more accurate operating parameters for the cleaning system 300. If the result is not out of bounds, the cleaning is performed according to the standard operating parameters. In some embodiments, the compliance judgment standard is set as flatness > p1cm and out-of-bounds area > a1m². In this embodiment, the preset flatness threshold p1 is 2cm, and the out-of-bounds area threshold a1 is 0.5m². These thresholds can be flexibly adjusted to adapt to walls with different degrees of wear in old buildings, improving the system's versatility.

[0044] In some embodiments, the stress sensing device presets a stress threshold of x MPa, captures the stress signal fed back from the wall during drilling in real time, and compares it with the threshold. When the stress value is greater than x (e.g., 5 MPa), the fully automatic drilling device immediately stops drilling to avoid damaging the deep structure of the wall. After stopping, the displacement sensing and hole depth calculation module calculates the thickness of the exterior wall decorative layer based on the current drill bit displacement. This application eliminates the need for manual monitoring of the drilling process, reducing labor costs and avoiding wall damage caused by human error.

[0045] In some embodiments, please refer to the following: Figure 2The cutting device 310 is located inside the sealing baffle 510 and is used to cut a working area of ​​50cm±10cm on the wall to avoid the risk of wall collapse caused by large-area operation. The cutting vibration device 340 uses high-frequency vibration to cut the wall. Its high-frequency vibration shovel has an amplitude of 3~5mm and uses an alternating action to vibrate the wall and separate it from the wall. The large pieces of waste after separation fall to the crushing device 350 above the dust collection hopper 520. The crushing device 350 is a single-row double-shaft toothed roller structure. The relative rotation of the toothed rollers achieves crushing, thereby crushing the waste into particles with a particle size ≤5cm. The crushed waste enters the collection pipe 530 through the dust collection hopper 520 to avoid large pieces of waste clogging the pipe and ensure smooth collection.

[0046] In some embodiments, please refer to the following: Figure 2 The sealing baffle 510 is made of flexible rubber material and has a U-shaped hollow design. It fits tightly against the wall. After the equipment is installed, the sealing baffle 510 uses its own flexibility to fit the uneven surface of the wall, forming a closed working space. During operation, the negative air pressure provided by the stabilization system 600 creates a micro-negative pressure environment in the closed space, further inhibiting the outward diffusion of dust.

[0047] In some embodiments, please refer to the following: Figure 3 The material collection pipe 530 is constructed in a multi-segment splicing form, with each segment being 3 meters long. The length can be adjusted through the splicing structure to adapt to buildings of different heights. Each segment is equipped with a flexible buffer baffle 531 at its end. When waste falls, it impacts the flexible buffer baffle 531 to slow down and prevent rapid descent from causing impact damage to the pipe. It is also sealed to the dust collection hopper 520 through a sealing ring 521 and sealed to the collection box 540. The sealed channel works in conjunction with the negative pressure of the stabilization system 600 to ensure that dust is transported to the collection box 540 along with the waste, preventing dust from drifting in the pipe.

[0048] In some embodiments, please refer to the following: Figure 6 The telescopic mechanism 360 is a hydraulically driven structure, in which the rotation and lateral movement of each device can be hydraulically driven. The hydraulic drive rod 361 drives the planing device 320, the scraping device 330, and the cutting device 310 to extend and retract by a small amount of 3 to 5 centimeters. Figure 6 The middle section compares the extension and retraction states of the hydraulic drive rod 361, and the extension stroke is controlled by the PLC controller to ensure that each device is always in close contact with the wall. In addition, each cleaning device can be driven by a motor through a belt, and the extension and retraction movements do not affect the power transmission.

[0049] In some embodiments, please refer to the following: Figure 5After the material identification system 200 completes the data acquisition of the wall surface, it transmits the construction distance parameters to the automatic limit system 400. The hydraulic lifting mechanism 420 receives the instruction and drives the support mechanism 410 to move closer to or further away from the wall via hydraulic oil pressure, adjusting the construction distance between the cleaning system 300 and the wall surface. The pulley 430 at the far end of the support mechanism 410 contacts the wall surface. When the equipment moves up and down, the pulley 430 rolls along the wall, reducing friction damage between the equipment and the wall surface. During operation, the hydraulic lifting mechanism 420 fine-tunes the position of the support mechanism 410 in real time to ensure that the construction distance remains within the preset range. Specifically, the hydraulic lifting mechanism 420 can be composed of hydraulic oil, a vane pump, an explosion-proof electromagnetic reversing valve, etc. The hydraulic oil enters the hydraulic cylinder through multiple valve groups to drive extension and retraction. The support mechanism 410 is fixedly connected to the equipment housing 100 to ensure limit stability.

Then adjust the cutting depth of the cutting device 310 so that it can completely cut the decorative layer of the wall surface. The cutting device 310 is installed on both sides of the equipment to cut out a working area of ​​about 50cm from the wall surface.

[0054] 4. The automatic limit system 400 uses the extension and retraction of the hydraulic lifting mechanism 420 to bring the cleaning system 300 into contact with the wall surface;

[0055] 5. The area to be cleaned is gradually moved down from top to bottom to complete the cutting, vibration, shoveling, and planing operations;

[0056] 6. During the cleaning process, the upper air inlet provides dust removal for the cleaning system 300, preventing the dust generated during the cleaning process from overflowing.
