However, if the pipeline robot's collision avoidance performance is poor, it may collide and be damaged during operation, thus affecting its efficiency and lifespan. Therefore, we propose a collision avoidance protection device for pipeline inspection robots. Utility Model Content

[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a collision protection device for a pipeline inspection robot, comprising protective plates 5 symmetrically arranged on both sides of the pipeline robot 1, the bottom of the protective plates 5 being rotatably connected to the support base 11, such as... Figure 2 , 3 As shown, to ensure stable rotational adjustment between the protective plate 5 and the support base 11, multiple openings 17 are made at the bottom of the protective plate 5. Multiple connecting blocks 16 are connected to one end of the support base 11. The connecting blocks 16 are rotatably connected to the openings 17 via a rotating shaft 20, and the support base 11 is vertically connected to the lower side of the pipeline robot 1.
[0024] like Figure 1 , 2 As shown, an extension plate 3 is inclinedly connected to the top of the protective plate 5. A buffer plate 7 is provided on the side of the extension plate 3 away from the pipeline robot 1. A first through groove 8 is provided on the extension plate 3, and a second through groove 19 is provided on the side of the first through groove 8 close to the pipeline robot 1. The second through groove 19 and the first through groove 8 are arranged in a stepped manner. The buffer plate 7 is provided through the first through groove 8, and an end plate 15 is fastened to one side of the buffer plate 7 and connected to the second through groove 19. During installation and use, the end plate 15 is fixedly connected to the side wall of the extension plate 3 by one of screw connection or bolt connection, which not only brings convenience to the installation, but also improves the practicality of the device.
[0025] like Figure 2 As shown, in order to achieve the telescopic adjustment of the buffer plate 7 and thus improve the buffering effect, in actual use, a sealing plate 10 that seals the second through groove 19 is tightly attached to the side of the end plate 15 extension plate 3 near the pipeline robot 1, and multiple return springs 12 are connected between the sealing plate 10 and the end plate 15. Multiple guide rods 14 are vertically connected in the circumferential direction in the second through groove 19, and a through hole 13 is opened on the end plate 15. The guide rods 14 are set through the through hole 13. Multiple positioning tubes 18 are set on the side wall of the sealing plate 10, and the ends of the guide rods 14 are coaxially connected in the positioning tubes 18. When the buffer plate 7 is subjected to pressure, it generates a force on the return spring 12, and under the elastic force of the return spring 12, the pressure can be effectively buffered. In actual use, a rubber pad is set between the end plate 15 and the sealing plate 10, which can further improve the buffering performance of the device.
[0026] like Figure 4 , 5 As shown, to achieve stable rotation of the protective plate 5, a second telescopic mechanism 9 is rotatably connected to the side of the protective plate 5 near the pipe robot 1, and the end of the second telescopic mechanism 9 is rotatably connected to the side wall of the pipe robot 1. Both ends of the second telescopic mechanism 9 are rotatably connected to second hinge seats 6, and the two second hinge seats 6 are respectively connected to the outer wall of the protective plate 5 and the pipe robot 1. At the same time, a first telescopic mechanism 2 symmetrically connected to the second telescopic mechanism 9 is rotatably connected to the upper side of the protective plate 5. The end of the first telescopic mechanism 2 is rotatably connected to the top of the pipe robot 1. Both ends of the first telescopic mechanism 2 are rotatably connected to first hinge seats 4, and the two first hinge seats 4 are respectively connected to the top of the protective plate 5 and the pipe robot 1.
[0027] In summary, when the anti-collision protection device of this pipeline inspection robot is in use, the protective plate 5 and the extension plate 3 can be rotated and adjusted along the end of the support base 11 under the push of the first telescopic mechanism 2 and the second telescopic mechanism 9. During use, the use of the protective plate 5 and the extension plate 3 can be adjusted according to the working environment of the pipeline robot 1. When the extension plate 3 is placed vertically, it can protect both sides of the pipeline robot 1. When protection is not required, the protective plate 5 and the extension plate 3 can be rotated and adjusted. At this time, when the protective plate 5 is rotated and perpendicular to the position of the support base 11, the extension plate 3 is located above the pipeline robot 1, which can effectively ensure the normal use of the pipeline robot 1. In terms of practicality, the first telescopic mechanism 2 and the second telescopic mechanism 9 are both electric telescopic rods. This utility model not only has a simple structure but also provides good protection for the pipeline robot 1, thereby effectively extending the service life of the pipeline robot 1.
