DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 , the present invention provides a gun barrel inner wall cleaning device, comprising: a support frame 100;

[0037] The laser cleaning component 200 is disposed inside the support frame 100 and is used to emit laser to clean the inner wall of the pipeline;

[0038] The walking assembly 300 is arranged outside the support frame 100 and is arranged in a surrounding distribution, and is used to drive the laser cleaning assembly 200 to move in the pipe;

[0039] The protection component 400 is disposed at the laser emitting end of the laser cleaning component 200 and is used to form an annular air curtain to protect the laser cleaning component 200 .

[0040] In this embodiment, a small cleaning device is formed by installing a laser cleaning component 200, a walking component 300 and a protective component 400 on a support frame 100. The device is not only easy to carry but also efficient to use. Through the light splitting structure, the device can be used to clean the irregular corners of the inner wall of the pipeline. The walking component 300 is a self-driving structure and can be independently disassembled and installed from the support frame 100. The device has a small overall size and does not require external power drive, making the overall installation and maintenance convenient. No external protective gas is required, thus reducing the external gas source and making the device suitable for field work. Through dual-path gas protection, the inner ring gas forms a conical air curtain to protect the protective mirror, and the outer ring gas blows along the axial direction of the pipeline to promptly clean the dust generated by cleaning.

[0041] In one embodiment, see Figure 2 The laser cleaning assembly 200 includes an optical cable connector 201, which is used to transmit the emitted laser. The laser passes through the protective mirror 202, the beam expander 203, the focusing mirror 204 and the beam splitter 205 in sequence. The laser is divided into two equal-range focusing beams by the beam splitter 205. The two focusing beams act on the inner wall of the pipe through the reflector group 206. The reflector group 206 is installed on the hollow shaft motor.

[0042] This embodiment is configured such that the laser beam passes through the protective mirror 202, the beam expander 203, the focusing mirror 204 and the beam splitter 205 in sequence, and is divided into two equal-range focusing beams by the beam splitter 205. The two equal-range focusing beams act on the inner wall of the pipe. As the walking component 300 moves along the pipe, the hollow shaft motor drives the reflector group 206 to rotate, so that the two equal-range focusing beams move in a spiral shape in the pipe, thereby cleaning the inner wall of the pipe.

[0043] In one embodiment, the focusing lens 204 is axially adjustable inside the support frame 100 , and the focal length is adjusted by changing the axial position of the focusing lens 204 .

[0044] This embodiment is configured in such a way that the focal length can be adjusted to suit different sizes of the inner wall of the pipe by changing the axial position of the focusing mirror 204 .

[0045] Specifically, the focusing mirror 204 can be controlled by an electric push rod.

[0046] In one embodiment, see Figure 3 The walking assembly 300 includes three groups of track assemblies 310 equidistantly distributed around the support frame 100 , and the track assembly 310 is connected to the support frame 100 through a connecting rod assembly 320 .

[0047] This embodiment is configured such that the walking components 300 surround the support frame 100 at intervals of 120°, and use a symmetrical layout to achieve automatic centering to form a mechanical balance, with a centering error of ≤0.5mm, ensuring the stability of other equipment carried thereon.

[0048] In one embodiment, see Figure 4 The track assembly 310 includes a support plate 311 and a flexible track 312. A driving wheel 313, a driven wheel 314 and an adjusting wheel 315 are arranged on the support plate 311 in sequence. The flexible track 312 is transmission-connected with the driving wheel 313, the driven wheel 314 and the adjusting wheel 315. The adjusting wheel 315 is installed on a tensioning slider 316. The tensioning slider 316 is slidingly connected to the support frame 100, and a wedge block 317 is provided at the end of the tensioning slider 316. A push block 318 abutting against the wedge block 317 is provided on the support frame 100. The push block 318 is movably connected to the support frame 100. The tensioning slider 316 moves on the support frame 100 to realize the tensioning adjustment of the flexible track 312.

[0049] This embodiment is configured such that by controlling the movement of the push block 318, the wedge block 317 pushes the tensioning slider 316 to move, thereby adjusting the tension of the flexible track 312, and further adjusting the fit between the flexible track 312 and the pipe wall.

[0050] In one embodiment, see Figure 5The connecting rod assembly 320 includes a first connecting rod 321, a second connecting rod 322 and a third connecting rod 323 which are spaced apart from each other. One end of the first connecting rod 321, the second connecting rod 322 and the third connecting rod 323 is axially connected to the support frame 100, and the other end is axially connected to a lining plate 324 fixed to the support plate 311;

[0051] It also includes a linkage rod 325, one end of which is movably connected to the first link 321 or the second link 322 or the third link 323, and the other end is axially connected to the slip ring 326. The slip ring 326 is slidably mounted on the support frame 100. The slip ring 326 slides on the support frame 100 and pushes the first link 321, the second link 322 and the third link 323 to rotate, thereby realizing the adjustment of the diameter of the flexible crawler 312.

[0052] This embodiment is configured such that, through the configuration of the first connecting rod 321, the second connecting rod 322 and the third connecting rod 323, the flexible track 312 can be stably supported, thereby ensuring the stability of the movement of the walking component 300 and being compatible with the remaining subsequent expansion functions, such as adapting to different pipe diameters and adjusting the tension of the flexible track 312.

[0053] Specifically, the slip ring 326 may be a knob-type self-tightening slip ring.

[0054] Specifically, the linkage rod 325 can be connected to one of the first link 321, the second link 322 and the third link 323. The movement of the slip ring 326 can push one of the links to rotate through the linkage rod 325, thereby realizing the rotation of the other two links, so that the distance between the flexible track 312 and the support frame 100 is adjusted.

[0055] By adjusting the position of the slip ring 326 on the support frame 100, one of the first link 321, the second link 322 or the third link 323 is rotated, and the distance between the flexible track 312 and the support frame 100 is adjusted, so that the walking mechanism can adapt to different pipe diameters for operation.

[0056] In one embodiment, see Figure 6 The protection component 400 includes a first guide ring 401, a second guide ring 402 is arranged on the outside of the first guide ring 401, a guide cavity 403 is arranged between the first guide ring 401 and the second guide ring 402, a base 404 is arranged at the end of the second guide ring 402, and fans 405 arranged equidistantly in a circle are arranged on the base 404. The fans 405 transport airflow into the guide cavity 403, and the airflow converges around the working end of the laser cleaning component 200 to form a protective air curtain.

[0057] This embodiment is configured such that airflow is transported into the flow guide cavity 403 by the fan 405, and the airflow converges around the working end of the laser cleaning component 200 to form a protective air curtain, thereby solving the problems of strong dependence on air sources, bulky equipment and insufficient uniformity of air curtains in field operations.

[0058] Specifically, the fan 405 is symmetrically arranged at 120°, and is directly driven by power supply to generate high-speed airflow, guiding three independent airflows to the guide cavity 403, forming a uniform annular air curtain surrounding the lens group, eliminating airflow blind spots, and forming a stable annular air curtain, eliminating the air compressor and air pipe, and only needs to be connected to the equipment power supply (such as DC 24V or AC 220V), which is particularly suitable for outdoor scenes without air source.

[0059] In one embodiment, see Figure 1 , also includes a monitoring component 500, which is arranged around the support frame 100 and is used to monitor the laser cleaning quality.

[0060] The monitoring component 500 uses a high-definition camera probe.

[0061] This embodiment is configured such that the monitoring component 500 is connected to an external monitoring system to transmit the images in the pipeline in real time, so that the staff can understand the cleaning conditions in the pipeline in real time and control the operation of the equipment in a timely manner.

[0062] In one embodiment, see Figure 7 and Figure 8 , further comprising a receiving assembly 600, the receiving assembly 600 comprising a receiving box 601, wherein the receiving box 601 is provided with a laser 602 and a controller 603 for controlling the laser cleaning assembly 200, the walking assembly 300 and the protection assembly 400;

[0063] The storage box 601 has storage slots for storing the controller 603 , the laser cleaning component 200 , the traveling component 300 and the protection component 400 .

[0064] This embodiment is configured such that when cleaning the pipeline, the laser cleaning component 200 is first taken out of the storage box 601 and placed in the pipeline, and the laser 602 in the storage box 601 transmits laser to the laser cleaning component 200, thereby reducing the weight of the cleaning head. After the cleaning operation is completed, the entire equipment can be stored for easy carrying and storage.

[0065] Specifically, universal wheels and handles may be installed on the storage box 601.

[0066] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.
