摘要: The present disclosure discloses a modular large spherical tank internal detection device with a self-locking function, and belongs to the technical field of safety detection of large spherical tanks. The detection device includes a transmission group and a detection group. A movable pin is matched with the rotation of a second motor in an unconnected state, so that inner central shafts rotate to realize up-down movement of a detecting instrument in a vertical plane. The movable pin is matched with the rotation of a first motor in a connected state, so that the whole detection device rotates round a central axis of a large spherical tank to realize horizontal circumferential movement of the detecting instrument. All detection of a spherical surface inside the large spherical tank can be completed by combining two types of movement of the detecting instrument.
