Example Embodiment

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like figure 1 As shown, a multi-camera video inspection device for reactor pressure vessel bolt holes includes: camera 2, multi-camera fixing bracket 3, connecting bracket 4, data fusion board 5, connecting wire 6 and data transmission optical cable. The cameras 2 are vertically arranged on the multi-camera fixed bracket 3 from top to bottom, and the multi-camera fixed bracket 3 is mechanically fixedly connected to the data fusion board 5 through the connection bracket 4. A data line 6 is used to transmit the image collected by the camera 2 to the data fusion board 5 through the data line 6, and the data fusion board 5 transmits the fused data to the control terminal through the optical fiber cable 7 for processing.

[0024] Wherein, the camera 2 specifically includes six megapixel-level industrial cameras, which are verticall...

Abstract

The invention relates to the multichannel video long distance transmission method technology field and especially relates to a reactor pressure vessel bolt hole multi-camera video inspection device. The device comprises cameras, a multi-camera fixing support, a connection support, a data fusion plate, a connection line and a data transmission light cable. The cameras are successively and vertically arranged on the multi-camera fixing support from top to bottom. The multi-camera fixing support is mechanically and fixedly connected to the data fusion plate through the connection support. A plurality of data lines are correspondingly arranged between the cameras and the data fusion plate so that images collected by the cameras are transmitted to the data fusion plate through the data lines. The data fusion plate transmits fused data to a control terminal through an optical fiber cable for processing. In the invention, the miniature industrial cameras with a high definition are verticallyarranged, the integrated level of a photographic mechanism is increased, the structure is simplified, simultaneously the structure of the device has high fault tolerance and maintainability compared with the structure in which the cameras and data are fused and integrated.

Description

technical field [0001] The invention belongs to the technical field of video non-destructive inspection and multi-channel video long-distance transmission method, and in particular relates to a multi-camera video inspection device for bolt holes of reactor pressure vessels. Background technique [0002] The video inspection of the bolt holes of the reactor pressure vessel is a necessary work during the overhaul of the nuclear power plant. The purpose is to check whether the threads are defective, rusted, and adhered to impurities, provide a basis for the maintenance and repair of the bolt holes, and create conditions for the smooth screwing in and out of the main bolts. In order to avoid bolt seizure. At the same time, due to its structural limitations, some parts cannot be directly inspected visually, and the radiation dose at the working position is high. Relying on the remote video inspection of the equipment can provide great help for this work. During the overhaul of n...
