Description

Technical Field

[0001] This utility model relates to the field of coal conveyor safety production technology, and in particular to a monitoring device for the operation of a coal conveyor. Background Technology

[0002] A coal conveyor is a mechanical device used to transport coal, typically found in power plants, mines, ports, and other locations, moving coal from storage points to boilers, loading / unloading points, or processing equipment. It usually consists of a conveyor belt, drive unit, idlers, tensioning device, etc., and can efficiently and continuously transport large quantities of coal. Its main functions are to ensure the stability and efficiency of coal transportation, reduce manual handling costs, improve the level of production automation, and simultaneously reduce coal dust pollution and losses during transportation.

[0003] To ensure the safe and stable operation of coal conveyors and prevent equipment failures and transport interruptions, a coal conveyor operation monitoring device is required. This device primarily consists of an inspection robot that integrates multiple sensors to monitor the coal conveyor's operating status in real time, promptly detect abnormalities, and take corresponding measures through alarms or linkage control systems. Its main functions are to improve the operational safety and efficiency of the coal conveyor, reduce downtime due to malfunctions, lower maintenance costs, and achieve remote monitoring and intelligent management, ensuring the continuity and reliability of coal transportation.

[0004] However, existing inspection robots have relatively limited protective measures against the high humidity, dust, and corrosive gases found in mine environments, making them prone to damage or performance degradation. While some systems can perform basic cleaning and dust control, the lack of efficient automatic cleaning capabilities means that robots are susceptible to environmental factors during long-term use, reducing their efficiency and stability. Furthermore, existing fire early warning and prevention measures primarily rely on heat source monitoring and alarm systems, lacking rapid response mechanisms and failing to effectively mitigate risks in the early stages of a fire, still relying excessively on manual intervention.

[0005] To address the above problems, a monitoring device for the operation of a coal conveyor is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a monitoring device for the operation of a coal conveyor, aiming to solve the problems that existing monitoring devices for the operation of coal conveyors are susceptible to the effects of humidity and dust in harsh environments, and have weak fire risk prevention and rapid response capabilities.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a monitoring device for the operation of a coal conveyor, comprising an inspection robot, wherein multiple drive devices are provided on the top of the inspection robot, an infrared thermal imager is installed on the bottom of the inspection robot, protective components are provided on the front and rear sides of the inspection robot to protect the precision instruments inside the inspection robot, and a cooling component is provided inside the inspection robot to actively cool down abnormal heat sources.

[0008] The protective components include an air intake hood, which is installed on the front side of the inspection robot. Two mounting rails are symmetrically arranged on the rear side of the inspection robot, and a dust cover is slidably connected between them. Both mounting rails have slots inside, and a card plate is inserted into the slot. A vibration motor is installed inside the inspection robot.

[0009] As a further description of the above technical solution:

[0010] The vibrating end of the vibrating motor abuts against the dust cover.

[0011] As a further description of the above technical solution:

[0012] The inspection robot is equipped with a variety of sensors inside, and the sensors are covered with protective covers. The inspection robot is made of corrosion-resistant alloy.

[0013] As a further description of the above technical solution:

[0014] Multiple drive devices are connected to guide rails pre-installed on the top of the coal conveyor belt.

[0015] As a further description of the above technical solution:

[0016] The cooling component includes a frame, inside which multiple cooling balls are placed. Cooling tanks are provided on both sides of the frame, and an electric switch is provided directly below the frame. The output ends of the two cooling tanks are connected to nozzles through pipes.

[0017] As a further description of the above technical solution:

[0018] The electric switch plates are symmetrically arranged on the bottom wall of the inspection robot, and both are rotatably connected to the inside of the bottom wall.

[0019] As a further description of the above technical solution:

[0020] The two nozzles are fixedly connected to the inside of the bottom wall of the inspection robot.

[0021] As a further description of the above technical solution:

[0022] The cooling ball is filled with coolant and carbon dioxide gas, and the cooling ball is made of a heat-sensitive material. The cooling tank is filled with high-temperature insulating foam.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a corrosion-resistant alloy is used to improve the corrosion resistance of the inspection robot's shell, and sealed protective covers are added to key electronic components to prevent dust and moisture intrusion. Furthermore, the robot is equipped with a self-cleaning system, such as a high-pressure airflow cleaning device, a dust filter, and a micro-vibration device, to periodically clean surface dust.

[0025] 2. In this invention, an infrared thermal imager on the inspection robot, combined with AI algorithms, precisely locates high-temperature points and is equipped with a cooling spray device. This device can spray inert cooling gases (such as CO2) to rapidly reduce the temperature of hot spots and prevent spontaneous combustion of coal. Furthermore, the robot can precisely spray high-temperature insulating foam to form a non-combustible coating in hazardous areas, preventing the temperature from rising further. This not only allows for timely risk control before a fire occurs but also significantly reduces the need for manual intervention, improving the safety and stability of the coal conveying system.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 3 This utility model provides an embodiment of a monitoring device for coal conveyor operation, comprising an inspection robot 1. The inspection robot 1 is internally equipped with various sensors, including temperature sensors, smoke sensors, and flow detection sensors, for real-time monitoring of the coal conveyor's operating status and acquisition of environmental parameters to ensure the safety and stability of the equipment. Sealed protective covers are installed on the outer sides of the various sensors to prevent damage to precision electronic components from dust, moisture, and corrosive gases, thereby improving the sensor's lifespan and detection accuracy. The outer shell of the inspection robot 1 is made of corrosion-resistant alloy material, possessing strong anti-oxidation and anti-corrosion capabilities, enabling long-term stable operation in high humidity and high dust environments. Multiple drive devices 2 are installed on the top of the inspection robot 1, each connected to a guide rail pre-installed on the top of the coal conveyor belt, allowing the inspection robot 1 to move freely along the guide rails, achieving omnidirectional inspection of the coal conveyor. An intelligent control system adjusts the inspection path and speed to adapt to different detection requirements. An infrared thermal imager 4 is installed at the bottom of the inspection robot 1 to monitor the temperature changes on the surface of the coal conveyor belt in real time, accurately identify abnormal heat sources, and analyze their development trends using AI algorithms for rapid early warning and corresponding measures. Protective components 3 are installed on the front and rear sides of the inspection robot 1 to effectively protect the precision instruments inside from external environmental influences. The inspection robot 1 also has a cooling component 5 inside, including a cooling spray system and an automatic spraying device. This component can quickly spray inert cooling gas or high-temperature insulating foam when abnormally high-temperature areas are detected, reducing the temperature of the heat source, preventing spontaneous combustion of coal, and minimizing human intervention, thereby improving the safety and automation level of the coal conveying system.

[0034] Reference Figure 1 - Figure 2The protective component 3 includes an air intake hood 301, which is installed on the front side of the inspection robot 1. The air intake hood 301 is mainly used to introduce external air and is equipped with a high-efficiency dust filter to reduce the entry of dust and particulate matter into the robot's interior, protecting internal precision sensors and electronic components. Two mounting rails 304 are symmetrically arranged on the rear side of the inspection robot 1. A dust cover 302 is slidably connected between the two mounting rails 304. This dust cover 302 is made of wear-resistant and anti-static material, effectively preventing dust from accumulating on the robot's surface. Each of the two mounting rails 304 has a slot 305 inside, into which a locking plate 306 is inserted. This locking structure allows for the stable fixing of the dust cover 302 while facilitating disassembly and maintenance, improving the cleaning and maintenance convenience of the inspection robot 1. The inspection robot 1 is equipped with a vibration motor 303. The vibration end of the vibration motor 303 is in contact with the dust cover 302. When the robot is running in a high dust environment, the vibration motor 303 can be started periodically. Through high-frequency vibration, the coal dust, powder or other small particles attached to the dust cover 302 are removed, ensuring the cleanliness of the dust cover 302 and thus reducing the impact of dust on the operation of the inspection robot 1.

[0035] Reference Figure 3 - Figure 4 The cooling component 5 includes a frame 501, inside which are placed multiple cooling balls 502. These cooling balls 502 are filled with coolant and carbon dioxide gas, which can rapidly release coolant when heated, effectively reducing the temperature of abnormal heat sources. The cooling balls 502 are made of a heat-sensitive material and will automatically rupture when exposed to high temperatures, allowing the internal coolant to rapidly diffuse to the hot spot area, thereby achieving rapid cooling and reducing the risk of spontaneous combustion of coal. Cooling tanks 503 are installed on both sides of the frame 501. The cooling tanks 503 are filled with high-temperature insulating foam. This foam can quickly cover the fire source after being sprayed onto the abnormal heat source area, forming a flame-retardant insulating layer, effectively preventing further spread of the fire, and simultaneously suppressing oxygen supply, achieving the dual effects of fire extinguishing and temperature control. An electrically operated switch 504 is located directly below the frame 501. The switch 504 is symmetrically positioned on the bottom wall of the inspection robot 1. Both are rotatably connected to the bottom wall via a rotating shaft structure, ensuring that the switch 504 can open quickly and precisely control the release of cooling material when the cooling ball 502 needs to be released, thus improving the stability of the cooling effect. The output ends of both cooling tanks 503 are connected to nozzles 505 via high-temperature and corrosion-resistant pipes. The nozzles 505 are fixedly installed inside the bottom wall of the inspection robot 1. Through an intelligent control system, cooling foam or coolant can be precisely sprayed based on the location of abnormal heat sources detected by the infrared thermal imager 4, achieving targeted cooling and ensuring the safe operation of the coal conveyor belt.

[0036] Working Principle: The inspection robot 1 operates along a guide rail pre-installed on the top of the coal conveyor belt via multiple drive devices 2 on its top, achieving a comprehensive inspection of the coal conveyor. Multiple sensors inside, including temperature sensors, smoke sensors, and flow detection sensors, collect real-time operating status data of the coal conveyor and transmit the data to the intelligent control system for analysis. An infrared thermal imager 4 is installed at the bottom of the inspection robot 1 to detect the temperature distribution on the surface of the coal conveyor belt and analyze temperature change trends using AI algorithms. When an abnormal heat source is detected, the intelligent control system activates the cooling component 5. First, the cooling channel is opened via the electric switch 504, causing the cooling ball 502 inside the frame 501 to release. The cooling ball 502 ruptures upon heating, releasing internal coolant and carbon dioxide gas, providing initial cooling to the high-temperature point. Simultaneously, high-temperature insulating foam in the cooling tanks 503 on both sides of the frame 501 is transported to the nozzle 505 via connected pipes. The nozzle 505 precisely sprays the insulating foam onto the abnormal heat source area, forming an insulating layer to prevent the spread of fire. An air intake hood 301 is installed on the front of the inspection robot 1 to prevent dust from entering and damaging internal components, while also reducing dust accumulation. A dust cover 302 is slidably connected between two mounting rails 304 on the rear of the inspection robot 1. The dust cover 302 is securely connected to the mounting plate 306 via a slot 305 and is driven by an internal vibration motor 303. When the inspection robot 1 is running, the vibration motor 303 vibrates periodically, causing coal dust and particulate matter adhering to the dust cover 302 to fall off, thereby keeping the protective components 3 clean.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
