|1. (WO2018157398) MINIATURE LIFT-TYPE VIDEO INSPECTION DEVICE|
|Applicants:||RESEARCH INSTITUTE OF NUCLEAR POWER OPERATION
CHINA NUCLEAR POWER OPERATION TECHNOLOGY CORPORATION,LTD.
|Title:||MINIATURE LIFT-TYPE VIDEO INSPECTION DEVICE|
The present invention relates to the field of nuclear power inspection apparatuses and provides a miniature lift-type video inspection device, comprising: a first support base and a second support base provided on one side, opposite to a guide rail, of a support bottom plate, a fixed shaft being provided between the first support base and the second support base, a coiling reel being sleeved on the fixed shaft, one end of the fixed shaft being connected to a turbine worm, the other end of the turbine worm being connected to a motor, and the motor being fixedly provided on the support bottom plate; and a cable, one end of which is fixedly provided on the coiling reel and the other end is connected to a camera module. The miniature lift-type video inspection device of the present invention can achieve lifting motion of the camera module in a narrow space by means of collecting and releasing motions of the flat cable which is driven by rotation of the miniature coiling reel, so that automatic video inspection of all layers of branch pipes and supports and hangers of a primary heat transmission system pipeline of a nuclear reactor can be finished.
