Description

Technical Field

[0001] The utility model relates to the technical field of inspection robots, in particular to an explosion-proof chassis of a wheeled inspection robot. Background Art

[0002] Wheeled inspection robots are a type of automated equipment commonly used in industrial environments, particularly for inspection work. They are typically equipped with wheels, enabling them to navigate complex terrains and perform tasks through automated technology, such as inspecting equipment, monitoring data, and taking photos or videos.

[0003] For example, a Chinese patent discloses an "outdoor wheeled inspection robot" with patent number: 202320082330.4. The patent includes a chassis assembly and a central mechanism provided on the chassis assembly. The chassis assembly is provided with a bottom shell assembly and a lower shell assembly that wrap the central mechanism. The lower shell assembly is sealed with an upper shell assembly, thereby improving the waterproof and heat dissipation functions of the inspection robot.

[0004] Although this patent solves the problem that existing wheeled inspection robots are generally powered by large batteries, during operation, a large amount of heat will be generated by the continuous operation of multiple internal modules. If the heat is not dissipated in time, it will easily cause aging of internal parts. However, there is still a disadvantage of poor protection. When designing and manufacturing the chassis of the wheeled inspection robot, special consideration should be given to the explosion-proof function so that it can operate safely in dangerous environments with explosions and large amounts of static electricity in the air. To this end, we provide a wheeled inspection robot explosion-proof chassis to solve the above problems. Utility Model Content
