Description

Technical Field

[0001] This invention relates to the field of thermal power plant technology, specifically to an intelligent inspection robot for thermal power plants and its inspection method. Background Technology

[0002] In the production and operation system of thermal power plants, the coal bunker is the core facility for coal storage, and its operational safety and stability are directly related to the continuous and efficient operation of the entire power generation process. During long-term storage, unloading, and transfer, coal particles are prone to generating a large amount of dust due to collisions, friction, and airflow. This type of dust not only poses a high risk of explosion, but long-term accumulation may also cause problems such as arching and blockage of the bunker walls.

[0003] The primary bottleneck in dust control at coal bunkers in thermal power plants currently lies in the limitations of the detection process. Existing models are insufficient to support timely follow-up processing: First, the manual inspection model involves maintenance personnel periodically carrying portable detection equipment to sample the area around the coal bunker or a limited area. However, due to long inspection cycles and narrow coverage, it cannot capture sudden changes in dust concentration in real time. Furthermore, the enclosed environment of the coal bunker and the frequent exceedance of dust concentrations pose safety hazards such as poisoning and suffocation for manual entry, resulting in missing detection data in high-risk areas. Second, the fixed-point dust sensor model, while enabling localized real-time detection, suffers from blind spots due to the large and complex internal space of the coal bunker and the fixed sensor placement. This leads to incomplete identification of key risk points where dust easily accumulates, such as corners of the bunker walls and unloading ports, leaving potential problems for subsequent processing.

[0004] Based on this, the present invention designs an intelligent inspection robot for thermal power plants and its inspection method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent inspection robot for thermal power plants and its inspection method, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent inspection robot for thermal power plants, comprising a carrier base, a sampling pump capable of sampling dust is fixedly installed at the forward end of the carrier base, a detection box is fixedly connected to the input end of the sampling pump, a light scattering sensor is fixedly connected to the upper end of the inner wall of the detection box, the light scattering sensor is electrically connected to a buzzer through a first wire, and the buzzer is fixedly connected to the carrier base; the carrier base is also provided with a purification component capable of adsorbing dust and reducing the concentration of airborne dust.

[0007] As a further embodiment of the present invention, the purification component includes two negative pressure cylinders capable of adsorbing dust. The two negative pressure cylinders are connected by a T-shaped connecting pipe. The output end of the T-shaped connecting pipe is fixedly connected to a mounting base. The lower surface of the mounting base is fixedly connected to a lifting rod capable of adjusting the height of the negative pressure cylinder. The lower end of the lifting rod is fixedly mounted on a support base via a fixing base. Inside the support base and directly below the fixing base, a first connecting pipe is fixedly connected. The lower end of the first connecting pipe is fixedly connected to a dust box capable of holding dust.

[0008] As a further embodiment of the present invention, the lifting rod is hollow; the T-shaped connecting pipe, the mounting base, the lifting rod and the connecting pipe are interconnected.

[0009] As a further embodiment of the present invention, a measuring device capable of measuring the weight of the dust box is fixedly connected between the lower end of the dust box and the inner wall of the support base, and a prompting device capable of issuing a warning when the dust box is about to be full is fixedly connected to the support base, and the prompting device is electrically connected to the measuring device.

[0010] As a further embodiment of the present invention, the detection box forms a sealed fluid passage with the dust box through the second connecting pipe, which can directionally introduce the dust-containing gas collected by the detection box into the dust box for storage, realize the closed-loop collection of dust samples throughout the entire process, and avoid the dust being directly emitted into the external environment, causing pollution or safety hazards.

[0011] As a further aspect of the present invention, a dust collection bag is fixedly connected inside the dust box, which is used to efficiently intercept and seal the dust-laden gas collected by the detection box and transported by the sampling pump, thereby realizing the directional collection and proper storage of dust samples.

[0012] As a further embodiment of the present invention, the air inlet of the negative pressure cylinder is provided with a filter screen capable of intercepting larger particles and coarse dust particles in the dust-laden gas.

[0013] An inspection method using an intelligent inspection robot in a thermal power plant is described below: S1: The sampling pump of the inspection robot draws in gas, and the dust concentration is detected by a light scattering sensor in the detection box.

[0014] S2: If the dust concentration in the air exceeds the standard, the negative pressure cylinder will work to adsorb the dust and transport it to the dust box through the first connecting pipe.

[0015] S3: The dust extracted by the sampling pump is transported to the dust box for storage through the second connecting pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Compared to a single adsorption structure, the synergistic adsorption design of the dual negative pressure cylinders significantly expands the adsorption coverage area, enhances the dust capture capability, efficiently adsorbs suspended coal dust in the coal bunker, greatly reduces the concentration of coal dust in the air, effectively purifies the air in the coal bunker, reduces the harm of coal dust to the respiratory system of workers, and reduces the safety hazard of coal dust explosion; while the adjustable height lifting rod allows the component to adapt to dust generation scenarios at different heights, breaking the limitations of fixed height adsorption and enhancing the versatility of the component.

[0017] 2. By combining the sampling pump and the detection box, air samples in the inspection area can be collected efficiently. The light scattering sensor can quickly and accurately obtain dust parameters. With the real-time alarm function of the buzzer, compared with manual inspection, it not only greatly improves the inspection efficiency, but also avoids the problem of missed detection of excessive dust due to human negligence during manual inspection, and provides timely risk warnings for staff.

[0020] Please see Figures 1-6 This invention provides a technical solution: an intelligent inspection robot for thermal power plants, comprising a carrier 1, a sampling pump 2 for sampling dust is fixedly installed at the forward end of the carrier 1, a detection box 3 is fixedly connected to the input end of the sampling pump 2, a light scattering sensor 4 is fixedly connected to the upper end of the inner wall of the detection box 3, the light scattering sensor 4 is electrically connected to a buzzer 6 through a first wire 5, and the buzzer 6 is fixedly connected to the carrier 1; the carrier 1 is also provided with a purification component capable of adsorbing dust and reducing the concentration of air dust.

[0021] When the intelligent inspection robot for the thermal power plant is in operation, it first moves stably within the coal bunker via its carrier 1. After reaching the designated inspection area, the sampling pump 2, fixedly installed at its forward end, starts. The sampling pump 2 generates negative pressure suction, continuously drawing air from the inspection area into the detection box 3, which is fixedly connected to its input end. As the dust-laden air flows through the detection box 3, the light scattering sensor 4, fixed to the upper inner wall, starts working. This sensor uses the principle of light scattering to detect parameters such as the concentration and particle size of dust in the air in real time. During the detection process, the light scattering sensor 4 maintains real-time electrical signal transmission with the buzzer 6 through the first wire 5. If the detected dust parameters exceed a preset safety threshold, the light scattering sensor 4 immediately sends a trigger signal to the buzzer 6, which then sounds an alarm to alert the staff. Simultaneously, throughout the entire inspection and sampling process, if the dust parameters exceed the preset safety threshold, the purification component installed on the carrier 1 immediately operates to adsorb dust from the air in the inspection area, continuously reducing the concentration of airborne dust in the surrounding environment.

[0022] The combination of sampling pump 2 and detection box 3 efficiently collects air samples from the inspection area. Light scattering sensor 4 quickly and accurately acquires dust parameters. Coupled with the real-time alarm function of buzzer 6, this significantly improves inspection efficiency compared to manual inspection and avoids the problem of missed dust detection due to human error during manual inspection, providing timely risk warnings to staff. On the other hand, the purification components enable the robot to purify dust while conducting inspections. When dust parameters exceed preset safety thresholds, it can immediately activate to reduce the air dust concentration in the inspection area. This improves the working environment of the power plant, reduces dust wear on equipment and harm to staff health, and achieves an integrated "detection + treatment" inspection mode, enhancing the overall effectiveness of dust control in the power plant.

[0023] As a further embodiment of the present invention, the purification component includes two negative pressure cylinders 7 capable of adsorbing dust. The two negative pressure cylinders 7 are connected by a T-shaped connecting pipe 8. The output end of the T-shaped connecting pipe 8 is fixedly connected to a mounting base 9. The lower surface of the mounting base 9 is fixedly connected to a lifting rod 10 capable of adjusting the height of the negative pressure cylinders 7. The lower end of the lifting rod 10 is fixedly mounted on a support base 1 via a fixing base 11. A first connecting pipe 12 is fixedly connected inside the support base 1 and directly below the fixing base 11. The lower end of the first connecting pipe 12 is fixedly connected to a dust box 13 capable of holding dust.

[0024] First, the two negative pressure cylinders 7 are activated and generate negative pressure suction to adsorb dust in the surrounding environment. The dual negative pressure cylinders expand the coverage and adsorption efficiency of dust adsorption. The adsorbed dust is collected through the T-shaped connecting pipe 8 between the two negative pressure cylinders 7. The T-shaped connecting pipe 8 provides a stable transport channel for the dust, ensuring that the dust adsorbed by the two negative pressure cylinders can be smoothly collected to the same output end. Then, the collected dust enters the mounting base 9, which is fixedly connected to it, through the output end of the T-shaped connecting pipe 8, and then enters the first connecting pipe 12 through the structure below the mounting base 9 (the first connecting pipe 12 is fixed inside the bearing base 1 and located directly below the fixed base 11, forming a continuous dust transport path with the mounting base 9, lifting rod 10 and other structures). Finally, the dust falls directly into the dust box 13, which is fixedly connected to it, through the lower end of the first connecting pipe 12, completing the dust collection. During this process, if it is necessary to adjust the adsorption range according to the height of the actual dust generation location, it can be achieved by adjusting the lifting rod 10. The upper end of the lifting rod 10 is fixedly connected to the mounting base 9, and the lower end is fixed to the bearing base 1 through the fixing base 11. The height of the mounting base 9 and the connected T-shaped connecting pipe 8 and negative pressure cylinder 7 are changed by the extension and retraction of the lifting rod 10, so as to ensure that the negative pressure cylinder 7 is always at the optimal adsorption height.

[0025] Compared to a single adsorption structure, the synergistic adsorption design of the dual negative pressure cylinder 7 significantly expands the adsorption coverage area, enhances the dust capture capability, efficiently adsorbs suspended coal dust in the coal bunker, greatly reduces the concentration of coal dust in the air, effectively purifies the air in the coal bunker, reduces the harm of coal dust to the respiratory system of workers, and reduces the safety hazard of coal dust explosion. The adjustable height lifting rod 10 allows the component to adapt to dust generation scenarios at different heights, breaking the limitations of fixed-height adsorption and enhancing the versatility of the component.

[0026] As a further embodiment of the present invention, the lifting rod 10 is hollow; the T-shaped connecting pipe 8, the mounting base 9, the lifting rod 10 and the connecting pipe 12 are interconnected.

[0027] As a further embodiment of the present invention, a measuring device 14 capable of measuring the weight of the dust box 13 is fixedly connected between the lower end of the dust box 13 and the inner wall of the support seat 1, and a prompter 15 capable of issuing a prompt when the dust box 13 is about to be full is fixedly connected to the support seat 1, and the prompter 15 is electrically connected to the measuring device 14.

[0028] Before dust collection begins, it is essential to ensure that the meter 14 and the indicator 15 are properly powered. The meter 14, fixedly connected between the lower end of the dust bin 13 and the inner wall of the support base 1, continuously bears the overall weight of the dust bin 13 and collects and monitors weight data. As the operation progresses, external dust continuously enters the dust bin 13, gradually increasing its overall weight. The meter 14 synchronously transmits the real-time detected weight data to the electrically connected indicator 15. The indicator 15 has a preset standard weight threshold for when the dust bin 13 is full. After receiving the weight data, it continuously compares and analyzes it. When the dust in the dust bin 13 accumulates to a weight that reaches or approaches the preset threshold (i.e., the dust bin 13 is about to be full), the indicator 15 triggers its alert function, emitting a warning signal through preset sound and light methods.

[0029] This system enables automated and precise monitoring and alerting of the dust bin 13's full state. Compared to the traditional method of relying on periodic manual inspections, it effectively avoids operational interruptions caused by dust bin overload or untimely inspections due to human negligence, significantly improving the continuity and efficiency of dust collection operations while reducing the labor intensity of manual inspections. Furthermore, the real-time weight monitoring by the meter 14 and the timely warnings by the alert device 15 allow operators to prepare for emptying the dust bin 13 in advance, reducing time wasted due to sudden shutdowns and effectively preventing dust overflow from polluting the work environment. This reduces safety hazards caused by dust diffusion and provides reliable support for environmental management and safety assurance at the work site.

[0030] As a further embodiment of the present invention, the detection box 3 forms a sealed fluid passage with the dust box 13 through the second connecting pipe 16, which can directionally introduce the dust-containing gas collected by the detection box 3 into the dust box 13 for storage, thereby realizing the closed-loop collection of dust samples throughout the entire process and avoiding the direct emission of dust into the external environment, which may cause pollution or safety hazards.

[0031] After the operation begins, the detection box 3 collects dust-laden gas samples according to a preset procedure or manual operation. The collected dust-laden gas, guided by the fluid pathway, flows from inside the detection box 3 to the dust collection box 13 through the second connecting pipe 16. During this process, the sealed passage strictly restricts the flow path of the dust-laden gas, preventing it from escaping into the external environment during transport. Ultimately, all the dust-laden gas is directed into the dust collection box 13 for centralized storage, completing a closed-loop operation from gas collection to dust storage. Once the dust collection box 13 reaches its storage threshold, subsequent processing is carried out.

[0032] The closed-loop collection mode throughout the entire process confines the dust-laden gas within the system consisting of the detection box 3, the second connecting pipe 16, and the dust box 13 through a sealed fluid passage, completely avoiding the problem of dust-laden gas being directly emitted into the external environment in traditional collection methods.

[0033] As a further embodiment of the present invention, a dust collection bag is fixedly connected inside the dust box 13, which is used to efficiently intercept and seal the dust-containing gas collected by the detection box 3 and transported by the sampling pump 2, so as to realize the directional collection and proper storage of dust samples.

[0034] As a further embodiment of the present invention, the air inlet of the negative pressure cylinder 7 is provided with a filter screen 17 capable of intercepting larger particles and coarse dust particles in the dust-laden gas.

[0036] S2: If the dust concentration in the air exceeds the standard, the negative pressure cylinder 7 will work to adsorb the dust and transport it to the dust box 13 through the first connecting pipe 12.

[0037] S3: The dust extracted by the sampling pump 2 is transported to the dust box 13 for storage through the second connecting pipe 16.
