Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to an installation structure of a detection device in a water-blocking conduit. Background Art

[0002] Riser casing is a pipe that extends from the offshore drilling platform to the shallow seabed. Its primary function is to isolate seawater, create a circulation channel for drilling fluid, and serve as a support structure for the offshore wellhead. During the drilling and completion process, the strength and safety of the riser are crucial to the safety of offshore drilling operations. Riser casings are approximately 12 meters long and come in diameters of 20 inches, 24 inches, and 30 inches, depending on their intended use and on-site operating conditions. Riser casings must be inspected for cracks, leaks, and deformation before use.

[0003] Since the existing detection device inside the watertight duct does not have an installation mechanism for the detection device, the detection device needs to be adjusted after installation according to watertight casings of different sizes during detection. However, the adjustment during detection is troublesome, and there is no specific device for fixing the watertight casing, which reduces the detection efficiency.

[0004] In the patent document with publication number CN213021676U3, a detection device inside a watertight duct is disclosed. A driving motor is provided to rotate a rotating shaft through a main gear and a slave gear. The rotating shaft drives the worm to rotate the worm wheel. The rotation of the worm wheel causes the screw to drive the moving wheel to achieve lifting and lowering, thereby facilitating the movement of the base. However, the detection device inside the watertight duct does not have a device for fixing the watertight duct when in use, which may result in reduced detection efficiency after the detection device is installed.

A detection probe 406 is fixedly connected to one side of the moving rod 404. When adjusting the position of the adjustment block 401, the position of the detection probe 406 shall be used as the basis until the detection probe 406 is aligned with the center line of the watertight conduit. Example

[0028] On the basis of the first embodiment, an adjustment plate 2 and a positioning plate 3 are provided on the top of the workbench 1, and a fixing mechanism 1 and a fixing mechanism 2 are provided on one side of the adjustment plate 2 and the positioning plate 3 respectively;

[0029] Fixing mechanism 1 includes a threaded rod 201, a rotating handle 202, a push plate 203, a rubber plate 204, a guide post 205, a curved platform 206, and a guide slot 207.

Guide slot 207 is provided on the top of workbench 1. The bottom of adjustment plate 2 has two guide bumps that mate with the two guide slots 207. Fixing mechanism 2 has the same structure as fixing mechanism 1. Rotating handle 1 202 controls the rotation of threaded rod 1 201, causing push plate 203 to move linearly in the direction of threaded rod 1 201. As push plate 203 moves downward, the rubber plate 204 at the bottom of push plate 203 clamps the watertight conduit.

[0030] A fixing plate 210 is provided on the left side of the fixing mechanism 1, and a threaded rod 208 is threadedly connected to one side of the fixing plate 210.

A rotating handle 209 is fixedly connected to one side of the threaded rod 208. A ball bearing is provided on the left side of the adjustment plate 2, and one end of the threaded rod 208 is connected to the inner ring of the ball bearing. When the rotating handle 209 is rotated, the adjustment plate 2 shows a linear motion in the direction of the threaded rod 208. A mounting platform 4 is provided on the right side of the fixing mechanism 2.

[0031] A detector 5 is fixedly connected to the top of the workbench 1, and the detector 5 is electrically connected to the detection probe 406. After adjusting the position of the detection probe 406, the detector 5 electrically connected to it is started, and then the pull rod handle 405 is controlled to move so that the detection probe 406 is extended into the interior of the watertight conduit for detection, and finally the result is fed back to the detector 5. A tripod 6 is fixedly connected to the bottom of the workbench 1, and there are four tripods 6 evenly distributed on the bottom of the workbench 1.

[0032] Working principle:

[0033] First, place one side of the watertight pipe on the fixing mechanism 2, and rotate the threaded rod 208 by rotating the rotating handle 209 on the other side, and then adjust the position of the adjustment plate 2 until one end of the watertight pipe is placed on the top of the arc platform 206. Then rotate the rotating handle 1 202 to control the rotation of the threaded rod 1 201. At this time, the push plate 203 moves linearly in the direction of the threaded rod 1 201. When the push plate 203 moves downward, the rubber plate 204 at the bottom of the push plate 203 will clamp the watertight pipe. The same operation is performed on the other side of the corresponding pipe to complete the fixation of the watertight pipe of common sizes.

[0034] Furthermore, through the detection mechanism set up, due to the different diameters of common watertight pipes, the rotation of the threaded rod three 402 can be controlled by rotating the rotating handle three 403. At this time, the adjustment block 401 performs linear motion in the direction of the threaded rod three 402. When the adjustment block 401 moves, it will drive the moving rod 404 to move, and a detection probe 406 is fixedly connected to one side of the moving rod 404. When adjusting the position of the adjustment block 401, the position of the detection probe 406 shall be used as the basis until the detection probe 406 is aligned with the center line of the watertight pipe.

[0035] Furthermore, after adjusting the position of the detection probe 406, the detector 5 electrically connected to it is started, and then the pull rod handle 405 is controlled to move so that the detection probe 406 is extended into the watertight conduit for detection, and finally the result is fed back to the detector 5.
