Embodiment approach

[0027] a) Install the fixing seat on the manhole of the voltage stabilizer, and fasten the fixing seat on the manhole surface with nylon fixing bolts.

[0028] b) Fix the mounting base to the fixing base and tightly fit the flange plate and the manhole flange through the fixing bolts, and install the support frame on the mounting base.

[0029]c) Install the winding mechanism on the mounting seat, the winding mechanism and the mounting seat are fixed by a quick locking structure, and the winding mechanism and the mounting seat are fastened together by the quick locking structure.

[0030] d) Assemble the camera with the flat cable. The camera and the flat cable are designed with a quick locking structure, and the camera and the cable are connected together with the quick locking structure.

[0031] e) Pass the flat cable around the reversing roller at the end of the bracket. Suspend the camera inside the barrel of the voltage stabilizer with a flat cable. The up and down tr...

Abstract

The invention discloses a CCTV video inspection device for a voltage stabilizer of a nuclear power station. A manhole is formed in the voltage stabilizer, the inspection device comprises a fixed seat,an installation support fixedly connected with the fixed seat, a support frame arranged on the installation support, a winding mechanism arranged at a rear end part of the installation support, a reversing component arranged on a front end part of the support frame, an inspection camera, a cable with a rear end fixed on the winding mechanism and a front end part fixedly connected with the inspection camera, the cable is flat, and various signal wires are arranged in parallel in the cable. The problem that the foreign matters are easily imported into a voltage stabilizer barrel since multiplecomponents of the traditional voltage stabilizer TV inspection equipment enter the voltage stabilizer barrel is solved; by adopting the flat anti-twisting cable, a signal wire, a power wire, a traction wire and a flexible shaft are integrated, the cable can be served as a traction wire as well as the signal wire and the power wire, and the problem the cable and the steel wire are mutually wound and knotted is solved.

Description

technical field [0001] The invention belongs to the field of nuclear power detection equipment, in particular to a CCTV video inspection device for a voltage stabilizer of a nuclear power plant. Background technique [0002] The existing CCTV inspection equipment for the voltage stabilizer consists of a winch, a support frame, a telescopic rod, a fall arrester, an inspection camera, a cable retractable plate, a half-flange fixed plate, and 7 parts. The manhole of the regulator enters the inside of the voltage stabilizer, and there are about 514 screws on the 7 parts. Too many foreign objects are introduced into the voltage stabilizer, which greatly increases the risk of introducing foreign objects into the voltage stabilizer. During the CCTV inspection of the voltage stabilizer, cables, hoist wire ropes, and anti-fall wire ropes entered from the manhole of the voltage stabilizer, a total of 4 cables. During the installation and inspection of CCTV equipment, wire ropes and c...
