The invention discloses a cable duct detection device with accurate measurement. The device comprises a walking assembly which is used for walking in a cable duct, a detection assembly which is arranged at the front end of the walking assembly and used for detecting the cable duct, and a power supply assembly which is arranged at the rear end of the walking assembly and used for supplying power tothe walking assembly and the detection assembly. The detection assembly comprises a detection shell, a controller, a laser detector connected with the controller, and a gyroscope arranged in the detection shell and connected with the controller. According to the invention, the controller monitors the angular velocity of the cable duct detection device through the gyroscope; if the gyroscope monitors that the pipeline detection device rotates, the pipeline detection device is started; when the cable pipeline detection device moves forwards, the controller can change the advancing speeds of thedifferent crawler wheels, so the cable pipeline detection device resets and continues to move forwards along the original advancing route, the cable pipeline detection device is prevented from rotating forwards in the cable pipeline, and the controller can accurately position the defect position according to the advancing distance of the cable pipeline detection device in the cable pipeline.
本发明公开了一种测量准确的电缆管道检测装置,包括用于在电缆管道内行走的行走组件、设于行走组件前端用于检测电缆管道的检测组件以及设于行走组件后端用于给行走组件和检测组件供电的供电组件,检测组件包括检测壳、控制器以及与控制器相连的激光检测器,检测组件还包括设于检测壳内并与控制器相连的陀螺仪。本发明中的控制器通过陀螺仪对电缆管道检测装置的角速度进行监测,若陀螺仪监测到管道检测装置发生转动,控制器会改变不同履带轮的行进速度,使得电缆管道检测装置复位并继续沿原本的行进路线前进,防止电缆管道检测装置在电缆管道内旋转前进,使得控制器可根据电缆管道检测装置在电缆管道内的行进距离对缺陷位置进行精准定位。
