[0030] This embodiment relates to a pipeline inspection device, referring to... Figures 1-5 It has a flat state and an upright state, including a mounting frame 10, a main unit chassis 20 set on the mounting frame 10, and a winding reel 30 set inside the mounting frame 10. A telescopic pull rod 40 is fixedly installed on the side of the mounting frame 10 away from the main unit chassis along the radial direction of the winding reel 30. At least one roller 50 is provided on the bottom of the mounting frame 10 away from the telescopic end of the pull rod 40.
[0031] The mounting bracket 10 is provided with a fixing part 101 for fixing the tie rod 40. The fixing part 101 protrudes from the plane where the tie rod 40 is located, and the fixing part 101 is also used to support the pipeline inspection device in a flat position. The mounting bracket 10 is also provided with a support part 102. The support part 102 and the roller 50 are in the same plane, and the support part 102 and the roller 50 cooperate to support the pipeline inspection device in an upright position.
[0032] In this embodiment, the pull rod 40 is a manual telescopic pull rod 40, specifically referring to the luggage pull rod 40, with one end being a fixed end and the other end being a telescopic end. There are two rollers 50, which are symmetrically arranged. In other embodiments, the pull rod 40 can also be other telescopic structures, such as an electric telescopic rod, etc., and the number of rollers 50 can also be set to one, three, or four, etc., according to actual needs.
[0033] In addition, it should be noted that the pipeline inspection device in the lying position is in the working state, that is, the pipeline inspection device can normally perform pipeline inspection and analysis, while the pipeline inspection device in the upright position is in the non-working state. The pipeline inspection device in the upright position occupies less space than the pipeline inspection device in the lying position, making it easier to store and transport.
[0034] By fixing a telescopic pull rod 40 to the bottom of the mounting frame 10 along the radial direction of the winding reel 30 and installing rollers 50 on the side of the bottom of the mounting frame 10 away from the telescopic end of the pull rod 40, the pipeline inspection device can be moved by the staff like a suitcase without manual handling, saving manpower and resources and reducing the labor intensity of the staff. Furthermore, by switching the pipeline inspection device between a flat and upright position, the space occupied is reduced, which facilitates the storage and transportation of the pipeline inspection device. This solves the problems of existing pipeline inspection devices being difficult to move, time-consuming and laborious in the moving process, and inconvenient in storage and transportation.
[0035] Furthermore, the support portion 102 includes a support leg fixedly mounted on the mounting bracket 10, with one end of the support leg fixedly mounted on the mounting bracket and the other end of the support leg extending in a direction opposite to the extension and retraction direction of the pull rod 40.
[0036] In this embodiment, there are two support feet and two rollers 50, so that the support feet and rollers 50 can stably support the pipe inspection device in an upright state. In other embodiments, the number of support feet and rollers 50 can be adjusted according to the actual situation, such as setting one roller 50 and two support feet, setting two rollers 50 and one support foot, or setting more than two rollers and more than two support feet, etc., which are not limited here.
[0037] Furthermore, the mounting bracket 10 includes a first bracket 11, a second bracket 12 and a third bracket 13 fixedly mounted on the first bracket 11, and a fourth bracket 14 disposed on the side of the second bracket 12 away from the first bracket 11. The first bracket 11 is arranged in a direction perpendicular to the pull rod 40, and the support feet and rollers 50 are both located on the first bracket 11. The second bracket 12 and the third bracket 13 are both perpendicular to the plane where the first bracket 11 is located. The third bracket 13 is located above the second bracket 12. The third bracket 13 and the fourth bracket 14 cooperate to support the main unit 20, and the first bracket 11, the second bracket 12, the third bracket 13 and the fourth bracket 14 cooperate to form an accommodating space for accommodating the winding reel 30.
[0038] Understandably, the winding reel 30 is housed in the accommodating space formed by the first bracket 11, the second bracket 12, the third bracket 13 and the fourth bracket 14, thereby achieving stable housing of the winding reel 30 and providing stable support for the main unit 20, thus improving the overall stability of the entire pipeline inspection device.
[0039] Furthermore, the first support 11 includes an upper support 111 and a lower support 112. The upper support 111 is vertically installed at one end of the top of the third support 13. The lower support 112 includes two vertical rods 1121 symmetrically arranged between the second support 12 and the third support 13, and the two ends of the vertical rods 1121 are respectively fixedly connected to the second support 12 and the third support 13.
[0040] The upper bracket 111 and the lower bracket 112 are both fixedly connected to the second bracket 12 and the third bracket 13 by welding. The upper bracket 111 is a "U"-shaped structure that is inverted on the third bracket 13, and the lower bracket 112 is staggered with the upper bracket 111, that is, the two vertical rods 1121 of the lower bracket 112 are located inside the opening of the upper bracket 111.
[0041] Furthermore, the second support 12 includes a symmetrically arranged left support 121 and a right support 122. Both the left support 121 and the right support 122 include U-shaped tube structures 123 with different lengths on both sides and a connecting tube 1233 connecting the long side tube 1232 and the end side tube of the U-shaped tube structure 123. The long side tube 1232 of the U-shaped tube structure 123 of the left support 121 and the right support 122 are both located at the center of the winding reel 30. One end of the connecting tube 1233 is fixedly connected to the short side tube 1231 of the U-shaped tube structure 123, and the other end extends along the length direction perpendicular to the short side tube 1231 of the U-shaped tube structure 123 and is bent outward and fixedly connected to the long side tube 1232 of the U-shaped tube structure 123.
[0042] A fixing plate 124 is also provided between the left support 121 and the right support 122 to make the connection between the left support 121 and the right support 122 more secure. The fixed end of the pull rod 40 is fixedly connected to the fixing plate 124 by bolts, so that the pipeline inspection device can be moved smoothly by the pull rod 40.
[0043] Furthermore, the third bracket 13 is arranged in the shape of a rounded rectangular frame, with one end of the third bracket 13 located above the winding reel 30. The upper bracket 111 and the lower bracket 112 are respectively fixedly connected to the upper and lower sides of the end of the third bracket 13 away from the winding reel 30.
[0044] In other embodiments, the third support 13 may also be configured as other shapes such as a rectangular frame or an arc frame, without further limitation.
[0045] Furthermore, the fourth support 14 includes two symmetrically arranged U-shaped bending structures 141, the openings of the two U-shaped bending structures 141 facing the second support 12 and the third support 13. One side of the winding reel 30 is accommodated in the openings of the two U-shaped bending structures 141, and the other side of the winding reel 30 is accommodated in the area formed by the cooperation of the second support 12 and the third support 13.
[0046] By setting the fourth bracket 14 as two symmetrically arranged U-shaped bending structures 141, the first bracket 11, the second bracket 12, the third bracket 13 and the fourth bracket 14 cooperate to form a structurally stable accommodating space, thereby achieving stable storage of the winding reel 30 and saving production costs.
[0047] Furthermore, the distance between the upper and lower sides of the two U-shaped bending structures 141 gradually increases along the radial direction of the winding reel 30. That is, the upper and lower sides of the two U-shaped bending structures 141 are arranged in a figure-eight shape, so that the U-shaped bending structures 141 will not affect the use of the winding reel 30 during pipeline inspection, making it convenient for operators to use.
[0048] Furthermore, a U-shaped handle 142 is provided between the two U-shaped bending structures 141. The two ends of the U-shaped handle 142 are fixedly connected to the closed ends of the two U-shaped bending structures 141, and the U-shaped handle 142 is located above the telescopic end of the handle.
[0049] This allows the U-shaped handle 142 to provide a point of force when external forces need to be applied to the pipeline inspection device, and also further improves the overall stability of the mounting bracket 10.
[0050] Furthermore, the upper bracket 111 is provided with two reinforcing plates 113, both of which are right-angled triangles. The two reinforcing plates 113 are respectively installed at the two support feet, and the two right-angled sides of the reinforcing plates 113 are respectively attached to and fixedly connected to the upper bracket 111 and the support feet.
[0051] By setting the reinforcing plate 113, the connection between the support part 102 and the upper bracket 111 is made more secure, so that the support part 102 can cooperate with the roller 50 to provide stable support for the pipeline inspection device in the upright state.
[0052] Furthermore, the upper support 111 is also provided with two connecting columns 114. The two connecting columns 114 are inclined and symmetrically arranged. One end of the connecting column 114 is fixedly connected to the side of the upper support 111 away from the reinforcing plate 113, and the other end of the connecting column 114 is fixedly connected to the top of the third support 13.
[0053] The use of two connecting columns 114 makes the connection between the upper bracket 111 and the third bracket 13 more secure, further improving the structural strength and overall stability of the mounting frame 10.
[0054] Furthermore, the winding reel 30 includes an upper mounting plate 31, a rotating shaft 32, a lower mounting plate 33, and a reel bracket 34 arranged coaxially from top to bottom. The upper mounting plate 31 is fixedly mounted on the top of the mounting frame 10, and the lower mounting plate 33 is fixedly mounted on the bottom of the mounting frame 10. The two ends of the rotating shaft 32 are rotatably connected to the upper mounting plate 31 and the lower mounting plate 33 respectively through bearings. A cable 35 is wound around the rotating shaft 32. The cable 35 is housed in the reel bracket 34. One end of the cable 35 is electrically connected to the main unit 20, and the other end of the cable 35 is connected to a detection camera 36.
[0055] Understandably, the detection camera 36 is connected to the main unit 20 via cable 35, enabling the detection camera 36 to transmit the condition inside the pipeline to the main unit 20 in real time, thereby achieving accurate detection and analysis of the pipeline.
[0056] Furthermore, the upper mounting plate 31 includes an annular plate 311 and four mounting ears 312. The four mounting ears 312 are evenly distributed along the circumferential direction of the annular plate 311, and are integrally formed with the annular plate 311. Compared to setting the upper mounting plate 31 as a complete plate, the production cost can be effectively reduced by setting the annular plate 311 and the mounting ears 312.
[0057] Furthermore, the main unit 20 includes a housing 21 and a cover 22. The housing 21 is fixedly mounted on the mounting ears 312 of the upper mounting plate 31. The housing 21 contains a main control circuit board 23 and a control keyboard 24. The cover 22 contains a display screen 25.
[0058] When inspecting the pipeline, staff can operate the relevant commands through the control keyboard 24, control the inspection camera 36 at the front end of the cable to move and capture video through the main control circuit board 23, and analyze the shooting results through the built-in program of the main unit 20. The real-time video captured by the inspection camera 36 can be transmitted to the display screen 25 for staff to view, assisting staff in conducting efficient and intuitive pipeline inspection.
[0059] Furthermore, a protective plate 26 is rotatably provided on the inner side of the cover 22. The size of the protective plate 26 is adapted to the display screen 25. Specifically, the size of the protective plate 26 is slightly larger than the size of the display screen 25, and the protective plate 26 is used to cover the surface of the display screen 25.
[0060] When the cover 22 is closed, the protective plate 26 can cover the surface of the display screen 25 to protect the display screen 25 and prevent the internal components of the cabinet 21 from scratching the screen. At the same time, when the cover 22 is open for pipeline inspection and analysis, opening the protective plate 26 can prevent the screen from reflecting light due to excessive external light, which would affect the staff's observation of the display screen 25.
[0061] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
