BIM (Building Information Modeling) data acquisition device for urban sewers

The invention discloses a BIM (Building Information Modeling) data acquisition device for urban sewers, and mainly relates to the field of BIM technology. The device comprises a frame, a first crawler wheel and a second crawler wheel are arranged on the frame, a buoyancy block is arranged at the bottom of the frame, an impeller driving mechanism is arranged at one end of the frame, a photographic mechanism is arranged at one end of the frame away from the impeller driving mechanism, an ultrasonic sensor is arranged at the bottom of the frame, a pH value detection mechanism is arranged on the frame, and an air quality sensor and a control box are arranged at the top of the frame. The device has the advantages that data of urban sewers can be measured, original data can be provided for establishing urban sewer BIMs, the workload of workers can be relieved, the operation states in the sewers can be provided for workers, the BIMs can be maintained conveniently, and operation management of the urban sewers is facilitated.
