Background: Due to the special working environment of the coal mine, there are gas, coal dust and other explosive substances, so the manual inspection is not only high labor intensity, but also high danger degree, there are blind spots in the inspection process, and the quality is difficult to be guaranteed. Replacing manual inspection with inspection robots can improve the inspection efficiency and ensure safe production. Summary of works: ① The mine intrinsically safe inspection robot adopts streamlined design. The inspiration comes from the agile posture of dolphins, the robot combines the beauty of nature with modern technology, which displays the ultimate dynamic beauty.② Equipped with a variety of sensors, the robot can collect on-site images, sound，temperature data and other parameters, predict and warn in advance to reduce the fault down time, and can monitor personnel intrusion, track foreign body , roadway deformation and other situations.③ This product is the robot with the smallest volume, the lowest weight, the lowest cost and the strongest AI among the same products, which can meet the needs of coal mine water pump room, substation, winch room and other key underground inspection areas. Design purpose: To solve various disadvantages of manual inspection in underground coal mines, to improve inspection efficiency, to ensure safe production, achieve the purpose of reducing staff and increasing efficiency, and promoting the high-quality development of the coal industry.Enforceability： This product adopts intrinsically safe design that meets the safety production requirements of coal mine underground, and selects a miniaturized drive mechanism with light weight, large climbing angle, and strong passability, which is suitable for various underground environment of coal mine。 Operability： It has both automatic and manual inspection functions, can connect with other monitoring platforms, achieve data exchange and sharing, and the operation is simple and easy to learn. Functionality: This product has intelligent recognition, audio analysis, infrared thermographic image acquisition, and temperature abnormal alarm functions, which can accurately determine the current operating status of the equipment, and based on big data analysis and early warning technology, it can predict and warn the operation failures of equipment in coal mines to reduce failure down time. Structural characteristics: The product adopts a streamlined structure with small volume, light weight, convenient installation, a small turning radius, and a large climbing angle. The circular steel pipe serves as the running track, which is lightweight, low-cost, and facilitates transportation and erection.The design inspiration comes from the agile posture of dolphins. Through the streamlined appearance and the integration of dolphin elements, the beauty of nature is combined with modern technology, and the curved surface is round and elegant, giving people a comfortable and pleasant visual experience, showing the ultimate dynamic beauty. The materials are mainly made of lightweight metals and environmentally friendly plastics such as PP and ABS, and all parts can be recycled and reused, and are in line with the requirements of green and environmental protection.
