Embodiment 1
[0041] see figure 1 , The inspection mirror of this embodiment includes a cylindrical probe 1 , a video monitor 2 and a host 3 . The probe 1 is connected to the host 3 through a cable 4 , and the host 3 is connected to the video monitor 2 .
[0042] The probe 1 is used to extend into the cable anchor head of the bridge and take pictures of the interior of the cable anchor head. The internal images include static images and / or dynamic images.
[0043] The host computer 3 is used to output the internal image captured by the probe 1 to the video monitor 2 and also used to control the rotation of the probe 1 .
[0044] The probe 1 is also provided with at least one LED, and the host 3 is also used to control the switch of these LEDs and adjust the brightness of these LEDs. The number of LEDs in this embodiment is four.
[0045] The video monitor 2 is used to display received internal images.
[0046] The host 3 includes a GPS signal receiving device, and the GPS signal receiv...

Abstract
The invention discloses an inspection mirror and a using method of the inspection mirror, wherein the inspection mirror comprises a cylindrical probe, a video monitor and a mainframe. The probe is connected with the mainframe via a cable; the mainframe is connected with the video monitor; the probe is used for inserting in an anchor-chain terminal of a bridge and shooting internal image of the anchor-chain terminal; the mainframe is used for outputting the internal image shot by the probe to the video monitor; the video monitor is used for displaying the received internal image; the inspection mirror further comprises a shell; the probe is packaged in the shell; the shell is a cone body, and the outer diameter of cone small surface of the shell is equal to the bottom diameter of the probe; the outer diameter of the cone large surface of the shell is greater than the bottom diameter of the probe. The inspection mirror and the using method of the inspection mirror of the invention overcome the shortcoming that the anchor-chain terminal of the bridge in the prior art is hard to detect and are convenient for observing the condition in the anchor-chain terminal of the bridge, and are very suitable for dynamic imaging in a narrow and small space.
Description
technical field [0001] The invention relates to an inspection mirror and a method of using the same. Background technique [0002] In recent decades, domestic arch bridges and cable-stayed bridges have developed rapidly. As the mainstream bridge type, it has more economic advantages than other bridge types, but it faces the problems of safety and durability of bridge cables. Due to multiple factors such as the complexity of the arch bridge and cable-stayed bridge structure itself, material defects, construction technology and quality problems, environmental corrosion, and inadequate maintenance management, HDPE (high-density polyethylene) sheaths are prone to appear in the cables during operation Damage, anchoring system corrosion and other diseases reduce the service life of the cables and bring safety hazards to the bridge. The stay cables, suspenders, and anchor cups made in my country in the early stage generally did not have drainage measures, but due to the poor compa...
