Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection, specifically an internal inspection camera guide device. Background Technology

[0002] Pressure pipelines are piping systems used to transport media such as gases, liquids, or steam. They withstand internal pressures higher than atmospheric pressure. These pipelines are widely used in industries such as petroleum, chemical, power, metallurgy, pharmaceuticals, and food processing. Designed to withstand internal pressures exceeding atmospheric pressure, pressure pipelines require high sealing performance to prevent media leakage and ensure safety and environmental protection. Therefore, the inspection of the inner wall of pressure pipelines is crucial. Pipeline inner wall inspection is a key step in ensuring the safe operation of industrial pipelines and assessing their structural integrity. Currently, mainstream non-destructive testing methods include: ultrasonic testing, high-frequency acoustic reflection, eddy current testing, X-ray testing, magnetic particle / magnetic flux leakage testing, digital image correlation (DIC) technology, and panoramic imaging. Among these, the super-central lens and digital image correlation (DIC) technology can achieve 360° panoramic imaging, overcoming the problem of inconsistent perspectives in traditional dual-camera systems and enabling the detection of minute defects.

[0003] However, since the detection camera needs to be installed on the outside of the camera when it is inserted into the pipe for detection, the size adjustment of the traditional guide mechanism is inconvenient and the use is cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an internal detection camera guide device, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an internal detection camera guiding device, including a guiding mechanism, the guiding mechanism including: an installation sleeve and a positioning support mechanism, the inner side wall of the installation sleeve having a through groove corresponding to the position of the positioning support mechanism, the positioning support mechanism including: a scissor support frame, a swing sleeve plate, and an adjusting screw, a movable rotating shaft being installed at the connection between the swing sleeve plate and the scissor support frame, a limiting roller bracket being installed on the outer side of the swing sleeve plate, a limiting roller being installed on the free end of the limiting roller bracket, and an engaging sleeve being installed on the outer side of the adjusting screw inside the scissor support frame.

[0006] As a further improvement of this utility model: a camera sleeve is provided on the inner side of the end of the mounting sleeve that is away from the adjusting screw.

[0007] As a further improvement of this utility model: a camera is installed inside the camera sleeve, and a transmission cable is installed at the other end of the camera.

[0008] As a further embodiment of this utility model: a movable shaft is connected between the engaging sleeve and the scissor support frame, and the movable shaft is movably connected to the mounting sleeve; the scissor support frame is rotatably connected to the swing sleeve plate through the movable rotating shaft.

[0009] As a further embodiment of this utility model: the limiting roller bracket is fixedly connected to the swing sleeve plate, and the limiting roller is movably connected to the limiting roller bracket.

[0010] As a further improvement of this utility model, the camera sleeve is fixedly connected to the mounting sleeve.

[0011] As a further embodiment of this utility model: the adjusting screw is rotatably connected to the meshing sleeve, and the inner diameter of the through groove is greater than the thickness of the positioning support mechanism.

[0012] As a further improvement of this utility model, the transmission cable is electrically connected to the camera.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The scissor support frames on both sides move with the meshing sleeve through the action of the movable shaft. The other end of the scissor support frame rotates with the swing sleeve through the movable shaft, thus realizing the overall extension of the scissor support frames on both sides. The limiting roller at the end of the swing sleeve will contact the inner wall of the pipe, which can guide and limit the overall guide mechanism while facilitating the overall movement inside the pipe to be tested.

[0014] The scissor support frame inside the positioning support mechanism can be adjusted in width using an adjusting screw, thus the entire guiding mechanism can be used for limiting and guiding movement of pipes with different inner diameters, thereby increasing the applicability of the entire device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, this embodiment provides an internal detection camera guiding device, including a guiding mechanism 1. The guiding mechanism 1 includes: a mounting sleeve 2 and a positioning support mechanism 3. A through groove 4 is formed on the inner side wall of the mounting sleeve 2 corresponding to the position of the positioning support mechanism 3. The inner diameter of the through groove 4 is larger than the thickness of the positioning support mechanism 3. The positioning support mechanism 3 includes: a scissor support frame 301, a swing sleeve 302, and an adjusting screw 304. A movable rotating shaft 306 is installed at the connection between the swing sleeve 302 and the scissor support frame 301. The scissor support frame 301 is connected to the swing sleeve 301 via the movable rotating shaft 306. The sleeve plate 302 is rotatably connected, and a limiting roller bracket 303 is installed on the outer side of the swing sleeve plate 302. The limiting roller bracket 303 is fixedly connected to the swing sleeve plate 302. A limiting roller 305 is installed on the free end of the limiting roller bracket 303. The limiting roller 305 is movably connected to the limiting roller bracket 303. An engagement sleeve 307 is installed on the outer side of the adjusting screw 304 inside the scissor support frame 301. The adjusting screw 304 is engaged and rotatably connected to the engagement sleeve 307. A movable shaft is connected between the engagement sleeve 307 and the scissor support frame 301, and the movable shaft is movably connected to the mounting sleeve 2.

[0019] like Figure 2-3 As shown, in this embodiment, a camera sleeve 5 is provided on the inner side of the end of the mounting sleeve 2 that is away from the adjusting screw 304. The camera sleeve 5 is fixedly connected to the mounting sleeve 2. A camera 6 is provided inside the camera sleeve 5. A transmission cable 7 is installed on the other end of the camera 6. The transmission cable 7 is electrically connected to the camera 6.

[0020] The working principle of this utility model is as follows: During use, after inserting the camera 6 into the camera sleeve 5 and securing it with tape or clamps, the guide mechanism 1 is positioned at the end of the pipe to be inspected. The through-slide 4 is then controlled to be perpendicular to the ground. A torque is applied to the adjusting screws 304 inside the two positioning support mechanisms 3. The engaging sleeves 307 outside the adjusting screws 304 will slide under the action of engagement. Simultaneously, the scissor-type support frames 301 on both sides will engage with the engaging sleeves via movable shafts. The cylinder 307 moves, while the other end of the scissor support frame 301 rotates with the swing sleeve plate 302 via the movable pivot 306, thus achieving the overall extension of the scissor support frame 301 on both sides. The limiting roller 305 at the end of the swing sleeve plate 302 contacts the inner wall of the pipe. Therefore, the limiting rollers 305 at the upper and lower ends of the two positioning support mechanisms 3 contact the upper and lower walls of the pipe respectively. Thus, by pushing the transmission cable 7 into the inside of the pipe, the guide mechanism 1 will drive the camera 6 to move and shoot at different positions inside the pipe.
