Embodiment Construction
[0038] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described implementation Examples are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0039] The difficulty in developing the video inspection robot for plum blossom holes on the ninth support plate is that the robot can only reach about 0.5m above the ninth support plate. How to insert the probe assembly into the narrow space of the existing steam generator (inaccessible area) The pipes to be inspected, and the mov...

The invention discloses a video inspection robot suitable for a ninth support plate of a steam generator. The video inspection robot comprises a shell, traveling mechanisms arranged on the shell, a flexible arm connected to the shell, a probe mechanism arranged at the end, far away from the shell, of the flexible arm, and a winding and unwinding mechanism and a control system which are arranged inthe shell, wherein the probe mechanism comprises a probe body connected in the shell; one end of the probe body is connected to the winding and unwinding mechanism, and the other end of the probe body is provided with a probe assembly for shooting; and the flexible arm is provided with a hollow hole used for allowing the probe body to penetrate. According to the video inspection robot suitable for the ninth support plate of the steam generator, the video inspection robot can carry the flexible arm and the probe mechanism to reach to-be-inspected pipes through the traveling mechanisms, the movement of the probe mechanism between the pipes is realized through the winding and unwinding mechanism under the regulation effect of the flexible arm, and the video inspection of the plum blossom hole blockage condition is further realized.
Description
technical field [0001] The invention relates to the detection field of steam generators and the technical field of robots, in particular to a video inspection robot for checking the blockage of plum blossom holes on the ninth support plate of steam generators. Background technique [0002] The steam generator is a heat exchanger that uses the heat of the primary circuit to heat the feed water of the secondary circuit to turn it into steam. In the process of operation, it is inevitable that sedimentation sludge will be generated on the tube sheet, support plate and outer wall of the tube, etc. During each outage for maintenance, regular cleaning and video inspection are required. [0003] The domestic CPR stack type steam generator is a vertical structure, which consists of tube plate, splitter plate, first, second to ninth support plates from bottom to top. Due to structural limitations, generally only manual video inspection and high-pressure cleaning between the tube shee...
