Description

Technical Field

[0001] The present invention relates to the technical field of chemical emergency response, in particular to a multifunctional disinfection robot capable of disinfecting both powder and liquid. Background Art

[0002] In the fields of chemical emergency response, decontamination is a key step in preventing and controlling the spread of hazardous substances. Traditional decontamination equipment is mainly divided into three categories: Liquid disinfection equipment: such as high-pressure cleaners and vehicle-mounted spray devices, which use pressure pumps to pressurize and atomize liquid disinfectants. They are suitable for liquid pollutants, but have limited effect on non-water-soluble dust.

[0003] Powder decontamination equipment: such as dry powder sprayers, which use compressed gas or mechanical force to spread powder. They are used for dust pollution, but are difficult to handle flowing liquids.

[0004] Simple combination equipment: The liquid and powder systems are mechanically spliced ​​together, requiring manual plugging and unplugging of pipes or replacement of nozzles to switch between them. Essentially, these systems are still two independent systems. Therefore, traditional disinfection equipment has the following technical bottlenecks: Single function: Most equipment can only spray liquid disinfectants (such as sodium hypochlorite solution) or powders (such as dry powder disinfectants) and cannot adapt to both forms of disinfectants at the same time. This leads to frequent equipment replacement during operations and low efficiency.

[0005] Limitations of spray coverage: Conventional spray devices rely on pressure pumps for diffusion, which have poor atomization effects on powders. Liquid disinfectants are prone to sag on vertical surfaces (such as walls and equipment surfaces) due to gravity, resulting in insufficient coverage uniformity.

[0006] Low degree of automation: Switching nozzles requires manual intervention, and the operation risk is high in narrow or high-risk environments (such as nuclear radiation areas and chemical leak areas); at the same time, the equipment lacks environmental perception capabilities and is difficult to adaptively adjust the spraying angle and range.

The wind auxiliary component 44 rotates during operation to generate a directional airflow, which can assist the first spray gun head 42 or the second spray gun head 43 in the spraying station to diffuse and spray the disinfection powder or disinfection liquid, thereby increasing the powder diffusion radius and the liquid adhesion rate, and realizing efficient powder-liquid collaborative operation. At the same time, thick smoke is often generated during the chemical emergency process.

The first spray gun head 42 and the second spray gun head 43 are both connected to the material box 3. The first spray gun head 42 or the second spray gun head 43 is used to spray disinfectant powder and disinfectant liquid respectively.

[0030] Through the gun head switching component 45, the first spray gun head 42 dedicated to powder or the second spray gun head 43 dedicated to liquid can be automatically moved to the spraying station in the hollow part inside the wind auxiliary component 44. The wind auxiliary component 44 rotates during operation to generate a directional airflow, which can assist the first spray gun head 42 or the second spray gun head 43 in the spraying station to diffuse and spray the disinfection powder or disinfection liquid, thereby increasing the powder diffusion radius and the liquid adhesion rate, and realizing efficient powder-liquid collaborative operation.

[0032] When the first spray gun head 42 is in the spraying position, the wind motor 445 drives the second pulley 447, which drives the inner cylinder 443 to rotate at high speed through the transmission belt. The fan blades 444 generate directional airflow, forming a negative pressure area at the spraying position, accelerating the powder to be sprayed out from the first spray gun head 42, and increasing the powder diffusion radius.

[0033] When the second spray gun head 43 is in the spraying position, the airflow is coupled with the liquid droplets from the second spray gun head 43 to form a fine atomization effect, and the adhesion density of the liquid agent is increased.

[0034] Furthermore, a motor box 448 is installed on the outside of the wind motor 445 and the second pulley 447, and the motor box 448 is fixedly arranged on the outside of the outer cylinder 441. A protective shell 449 is installed on the outside of the first pulley 446 and the transmission belt. The protective shell 449 is movably mounted on the outside of the inner cylinder 443 and is fixedly connected to the inner wall of the outer cylinder 441 and the support frame 442.

[0035] Specifically disclosed, the gun head switching assembly 45 includes a moving mechanism 451 and a rotating mechanism 452. The moving mechanism 451 is used to drive the wind auxiliary assembly 44 to move horizontally so as to separate it from the first spray gun head 42 or the second spray gun head 43. The rotating mechanism 452 is used to drive the first spray gun head 42 and the second spray gun head 43 to rotate.

[0036] Specifically disclosed, the moving mechanism 451 includes: A moving motor 4511 is embedded in the bracket 41; The screw rod 4512 is rotatably mounted on the bracket 41 via a bearing seat. The ends of the screw rod 4512 and the end of the output shaft of the moving motor 4511 are fixedly sleeved with bevel gears 4514, and the two bevel gears 4514 are meshed and connected. The threaded block 4513 is threadedly connected to the outside of the screw rod 4512 , and the top of the threaded block 4513 is fixedly connected to the wind assist assembly 44 .

[0037] The moving motor 4511 is started, and drives the screw rod 4512 to rotate through the bevel gear 4514.

[0038] The threaded block 4513 moves axially along the screw rod 4512 , driving the wind assist assembly 44 to move horizontally.

[0039] Specifically disclosed, the rotation mechanism 452 includes: The arc-shaped slide rail 4521 is fixedly mounted on the bracket 41 . Two sliders 4524 are slidably mounted on the inner wall of the arc-shaped slide rail 4521 . The first spray gun head 42 and the second spray gun head 43 are respectively disposed through the two sliders 4524 . A support bar 4522 is fixedly mounted on the top of the arc-shaped slide rail 4521; The rotating motor 4523 is fixedly mounted on the top of the support bar 4522; The connecting member 4525 is fixedly connected between the output shaft of the rotating motor 4523 and the two sliders 4524 .

[0040] The rotating motor 4523 drives the connecting part 4525 to rotate, driving the slider 4524 to move along the arc-shaped slide rail 4521, thereby driving the first spray gun head 42 or the second spray gun head 43 to move to the rear of the inner cylinder 443. When the inner cylinder 443 is reset under the action of the moving mechanism 451, the gun head located directly behind the inner cylinder 443 can enter the spraying station inside the inner cylinder 443, thereby realizing automatic switching of the gun head.

[0041] Furthermore, the angle adjustment assembly 46 includes a rotating platform 461 and a flip mechanism 462 . The rotating platform 461 is rotatably disposed on the walking body 1 , and the flip mechanism 462 is installed between the rotating platform 461 and the bracket 41 .

[0042] The rotating motor starts and drives the rotating platform 461 after being decelerated by the gear box. The encoder at the bottom of the rotating platform 461 records the rotation angle, forming a closed-loop control.

[0043] Furthermore, a rotating motor is installed inside the walking body 1, and the rotating motor is in transmission connection with the rotating platform 461, and the rotating motor can drive the rotating platform 461 to rotate.

[0044] It should be emphasized that both the rotary motor 4523 and the rotating motor are provided with electromagnetic brakes, which can be used to lock the slider 4524 and the rotating platform 461.

[0045] Specifically disclosed, the flip mechanism 462 includes: Support seat 4621; The flip seat 4622 is rotatably mounted on the top of the support seat 4621 , and the top of the flip seat 4622 is fixedly connected to the bracket 41 ; The flip motor 4623 is embedded on the outside of the support base 4621; The rotating shaft 4624 is fixedly inserted into the inner wall of the flip seat 4622, and the end of the rotating shaft 4624 passes through the support seat 4621; The worm 4625 is fixedly mounted on the output end of the flip motor 4623; The worm wheel 4626 is fixedly sleeved on the outer side of the end of the rotating shaft 4624, and the worm wheel 4626 and the worm 4625 are meshed and connected.

[0046] The flip motor 4623 drives the worm 4625 to rotate, which drives the worm wheel 4626 and the rotating shaft 4624 to rotate. The flip seat 4622 rotates along with the rotating shaft 4624 to adjust the pitch angle of the bracket 41.

[0047] Furthermore, a protective box is installed on the outside of the flip motor 4623, the worm 4625 and the worm wheel 4626, and the other end of the worm 4625 is rotatably connected to the inner wall of the protective box.

[0048] During use, the surveillance camera 2 is used to scan the work area to check the contaminated area. For aerosol or water-insoluble pollutants, such as dust-like toxic agents, the first spray gun head 42 is selected to perform the powder decontamination mode. For liquid pollutants, such as acid or biological contamination liquid, the second spray gun head 43 is selected to perform the liquid decontamination mode.

[0049] The moving motor 4511 is started, and the screw rod 4512 is driven to rotate through the bevel gear 4514. The threaded block 4513 moves axially along the screw rod 4512, driving the wind auxiliary component 44 to move horizontally. The rotating motor 4523 drives the connecting part 4525 to rotate, driving the slider 4524 to move along the arc slide rail 4521, thereby driving the first spray gun head 42 or the second spray gun head 43 to move to the rear of the inner cylinder 443. When the inner cylinder 443 is reset under the action of the moving mechanism 451, the gun head located directly behind the inner cylinder 443 can enter the spraying station inside the inner cylinder 443, thereby realizing automatic switching of the gun head.

[0050] When the first spray gun head 42 is in the spraying position, the wind motor 445 drives the second pulley 447, which drives the inner cylinder 443 to rotate at high speed via the transmission belt. The fan blades 444 generate a directional airflow, forming a negative pressure zone at the spraying position, accelerating the spray of the powder from the first spray gun head 42 and increasing the powder diffusion radius. When the second spray gun head 43 is in the spraying position, the airflow couples with the droplets from the second spray gun head 43, forming a fine atomization effect, increasing the adhesion density of the liquid agent, and achieving efficient powder-liquid synergy.

[0051] At the same time, during the chemical emergency process, thick smoke is often generated. The wind auxiliary component 44 can be used to blow away part of the thick smoke in the moving direction and the spraying direction, making it easier for the monitoring camera 2 to monitor and view, and improving the spraying accuracy of the disinfection powder or disinfection liquid.

[0052] Example 2: According to the attached Figure 10 -Attached Figure 12 As shown, based on the first embodiment, a gas sensor array, a dust concentration sensor, a temperature and humidity sensor, and a liquid sensor can be integrated at the front end of the walking body 1; The gas sensor array monitors the concentration of toxic gases in the working environment and identifies the type and diffusion range of pollution. The dust concentration sensor detects the concentration of suspended particulate matter in the air, the temperature and humidity sensor detects the ambient temperature and humidity, and the liquid sensor is used to detect the conductivity of the liquid.

[0053] The internal control system of the walking body 1 determines the pollution type based on the sensor data: 1. Dust pollution, such as toxic dust, radioactive dust, and water-insoluble particulate pollutants. Specifically, PM2.5 and PM10 concentrations must exceed thresholds (e.g., PM10 > 1000 μg / m³), the particle size distribution peak must be between 1 and 50 μm, the volatile organic compound (VOC) concentration must be normal or slightly elevated, the relative humidity must be < 60%, and visual inspection must show no reflective areas, indicating no obvious traces of liquid. Select powder mode: The first spray gun head 42 uses disinfectant powder; The wind assist component 44 adopts a high speed mode (1800-2000RPM) to form a wide range of diffusion; Prioritize horizontal spraying to cover a large area of ​​suspended dust.

[0054] 2. Liquid contamination, such as acid leakage, biological contamination, and oil contamination. Specifically, it detects abnormal concentrations of specific gases (such as acidic gases such as HCl and H2S), normal dust concentrations, but significantly increased humidity (>80%), and abnormal liquid conductivity detected by liquid sensors; Select liquid mode: The second spray gun head 43 uses a cleaning liquid; The wind assist component 44 adopts a medium speed mode (1200-1500 RPM) to enhance droplet atomization but avoid excessive blowing; Tilt at a 45° angle to prioritize coverage of pollution sources and flow paths.

[0055] 3. Complex pollution, such as mixed pollution (dust + liquid + toxic gas) after chemical explosions, and areas with overlapping multiple types of pollutants. Specifically, the detection range is where multiple pollutants exceed the standard (e.g., PM10 > 500 μg / m³ and SO2 > 50 ppm), particle size distribution shows multiple peaks (e.g., significant peaks in both 1-10 μm and 100-500 μm), and temperature and humidity fluctuate greatly (temperature change rate > 2°C / minute). The spraying pattern is selected in stages: S1. Staged treatment (a 50% drop in SO2 concentration after the first stage triggers the second stage): Phase 1: The second spray gun head 43 uses the cleaning liquid to quickly suppress; Second stage: the first spray gun head 42 uses disinfectant powder to absorb the remaining pollutants; Wind assist assembly 44: Stage 1: Low speed mode (1000RPM) to avoid disturbing the smoke; Second stage: High speed mode (1800RPM) to enhance powder diffusion.

[0056] The gas sensor array, dust concentration sensor, temperature and humidity sensor, and liquid sensor work together to build a pollution signature model based on four dimensions: gas composition, particulate matter characteristics, environmental parameters, and liquid conductivity. This model uses quantitative indicators to achieve objective judgment and improve the accuracy of pollution type identification. The sensor array continuously collects data at a frequency of 10Hz, tracking pollution spread trends in real time and dynamically updating pollution type judgment results.

[0057] To address dust pollution, the "high-speed wind assistance (1800-2000RPM) + horizontal spraying" design increases the diffusion radius of the disinfection powder by 40% and the coverage area by 60%, thus avoiding excessive use of powder. For liquid pollution, "medium-speed atomization (1200-1500RPM) + 45° inclined spraying" increases the liquid adhesion rate by 30% and reduces liquid waste; For complex pollution, staged treatment (first suppression, then adsorption, and finally flushing) avoids "one-size-fits-all" spraying, improves disinfection efficiency, and reduces the total consumption of disinfectants.
