The invention discloses a mini type lift type video inspection device and relates to the field of nuclear power inspection equipment. The mini type lift type video inspection device comprises a first supporting base, a second supporting base and a cable, wherein the first supporting base and the second supporting base are arranged on one side, opposite to a guide rail, of a supporting bottom plate, a fixed shaft is arranged between the first supporting base and the second supporting base, a wire coiling and winding drum is arranged on the fixed shaft in a sleeving mode, one end of the fixed shaft is connected with a turbine worm, the other end of the turbine worm is connected with a motor, the motor is fixedly arranged on the supporting bottom plate, one end of the cable is fixedly arranged on the wire coiling and winding drum, and the other end of the cable is connected with a camera module. The mini type lift type video inspection device disclosed by the invention can achieve lifting motion of the camera module in a narrow space by collecting and releasing motion of the flat cable which is driven by rotation of the mini type wire coiling and winding drum, so that automatic video inspection of all layers of a branch pipe support post of a primary heat transmission system pipeline of a nuclear reactor can be finished.
Description
technical field [0001] The invention relates to the field of nuclear power inspection equipment, in particular to a miniature liftable video inspection device. Background technique [0002] With the rapid development of China's nuclear power industry, the safety of nuclear equipment has always been concerned. Visual inspection is one of the main means of in-service inspection of nuclear power plants and is widely used in in-service inspection of nuclear power plants. [0003] The branch pipe supports and hangers of the main heat transfer system are the core equipment of nuclear reactors. The vibration during operation will cause problems such as wear of wear-resistant plates, deviation of support and hangers, nut drop-off, and wear of pipes, which require frequent inspection. In the mainstream reactor type of my country's nuclear power plants, there are 5 layers of pipe branch pipes in each row of the main heat transfer system, and there are 4 to 5 support hangers on each l...
