Technical Field
[0001] This utility model relates to the field of pipeline inspection equipment, and in particular to a support for pipeline QV inspection. Background Technology
[0002] Currently, pipeline periscope inspection is a method of inspecting pipelines inside inspection wells using a pipeline periscope, called QV inspection. QV inspection is a type of pipeline endoscopic inspection technology that not only solves the problems of insufficient camera distance for pipeline length and slow upload speed leading to synchronization issues, but also accurately determines pipeline material defects, corrosion levels, and their specific locations. Its inspection results can serve as a basis for assessing the health status of pipelines.
[0003] The following problems currently exist;
[0004] Most existing pipeline QV inspections involve placing a periscope inside the communication shaft for inspection. To avoid manual hand-held operation of the periscope, various brackets for QV inspections have emerged on the market. However, most brackets require fixing with bolts or expansion screws before use. This method not only requires preparation before inspection but also easily damages the structure above the communication shaft due to the screw fixing method. Utility Model Content

[0026] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1
[0028] Reference Figures 1 to 7This embodiment provides a bracket for pipeline QV testing, including a pan-tilt unit 100, which is a hollow column with a slot 101 through the top; a fixing mechanism 200, which includes several sets of chucks 201 and dials 202, and is located inside the pan-tilt unit 100; and a support mechanism 300, which includes several sets of support mechanisms 300, each set including a leg 301 and a hook leg 302, with the leg 301 hinged to the bottom of the pan-tilt unit 100.
[0029] The chuck 201 is generally elliptical in shape. The inner wall of the gimbal 100 has a limiting groove A102. The chuck 201 is rotatably connected inside the limiting groove A102. By rotating several sets of elliptical chucks 201, the periscope is clamped to complete the action of fixing the periscope.
[0030] The inner wall of the gimbal 100 has a limiting groove B103. A through hole 102a is provided between the limiting groove A102 and the limiting groove B103. The dial wheel 202 is rotatably connected inside the limiting groove B103. A gear 201a is connected to the axis of the outer wall of the chuck 201. The gear 201a passes through the through hole 102a and is rotatably connected to the inner wall of the dial wheel 202. By rotating the dial wheel 202, the gear 201a drives several sets of chucks 201 to rotate, and the rotation of the several sets of chucks 201 clamps the periscope.
[0031] The top of the gimbal 100 has a through groove 104, and the top of the dial 202 has a lever 202a. The lever 202a passes through the groove 104 and is slidably connected inside the groove 104. During normal use, the dial 202 can be rotated by moving the lever 202a.
[0032] Hook 302 is hinged to the bottom of support 301, and a barb is provided at the end of hook 302. In use, hook 302 is located at the edge of well opening, and the barb at the end of hook 302 hooks the well opening of the communication well to complete the overall fixation of the support.
[0033] The outer wall of the support leg 301 has a storage groove 301a, and the hook foot 302 is placed inside the storage groove 301a; this structure makes the support easier to store and smaller in size when stored.
[0034] Working principle: When fixing the bracket, several sets of hook feet 302 are pulled out from the storage groove 301a, so that the ends of the hook feet 302 are located inside the well opening. Then, while keeping the several sets of hook feet 302 parallel to the ground, the several sets of support feet 301 are rotated. As the several sets of support feet 301 rotate, the radial distance between the several sets of hook feet 302 will become greater and greater, until the several sets of hook feet 302 are all hooked on the edge of the communication well opening. Then, the periscope is inserted through the slot 101 of the gimbal 100. After adjusting the periscope to a suitable height, the lever 202a is turned, which drives the dial wheel 202 to rotate. The dial wheel 202 drives the several sets of chucks 201 to rotate through several sets of gears 201a. By rotating the elliptical chucks 201, the periscope is clamped.
