Description
Technical Field
[0001] The utility model relates to the technical field of pipeline detection, and particularly relates to a rotating mechanism of a controllable radar system in a pipe. Background Art
[0002] At present, in common radar systems in pipes, a geological radar component is usually directly installed above a traveling component. The limitation of this configuration is that the detection range of the geological radar mainly focuses on the upper region of the pipeline, resulting in the inability to effectively detect the surrounding areas of the pipeline. At the same time, in some pipeline bottoms, there is often silt or sewage accumulated, and the existing radar systems are difficult to penetrate these media for effective detection, resulting in the lack of information in the bottom region of the pipeline.
[0003] This structural design greatly limits the detection ability of the radar system in the pipe and cannot comprehensively obtain the status information of the pipeline. Due to the lack of detection of the surrounding and bottom regions of the pipeline, potential pipeline defects or damages may be overlooked, affecting the safe operation of the pipeline. In addition, the limitations of detection also increase the complexity and cost of subsequent maintenance and repair work. Based on this, we propose a rotating mechanism of a controllable radar system in a pipe. Summary of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.
[0026] This embodiment proposes a radar system rotation mechanism in a thyristor, such as Figures 1 to 4As shown, it includes a traveling component 3 that can travel inside the pipeline 1. A liftable fixed seat 5 is arranged vertically at the upper end of the traveling component 3. A liftable ground penetrating radar 9 is arranged vertically at the upper end of the fixed seat 5. When inspecting the municipal rainwater and sewage pipeline, first, the rotating lens 7 is lifted and lowered to the center of the pipeline 1 to be detected. Then, the ground penetrating radar 9 is lifted and lowered to make it close to the side wall of the pipeline 1 to be detected. Finally, the detection operation of the municipal rainwater and sewage pipeline is completed through the ground penetrating radar 9. In practical applications, since the ground penetrating radar 9 is fixedly installed, the ground penetrating radar 9 can only detect the upper part of the pipeline 1, and the surrounding of the pipeline 1 cannot be detected, which affects the detection accuracy. Therefore, a rotatable rotating shaft tube 55 is installed at the end of the fixed seat 5. A second lifting component 8 is installed on the outer circumferential surface of the rotating shaft tube 55. The other end of the second lifting component 8 is connected to the ground penetrating radar 9. The ground penetrating radar 9 is driven to rotate around the center of the pipeline 1 by the rotatable rotating shaft tube 55, realizing the comprehensive detection of the pipe wall. In this embodiment, the second lifting component 8 is composed of a second X-shaped movable rod 81 and a second electric cylinder 82. The second X-shaped movable rod 81 is composed of two rods that rotate and cross. The two ends of one rod are respectively movably connected to the outer circumferential surface of the rotating shaft tube 55 and the bottom of the ground penetrating radar 9. One end of the other rod is movably connected to the bottom of the ground penetrating radar 9, and the other end is slidably assembled on the rotating shaft tube 55 along the axial direction of the rotating shaft tube 55. The end seat of the second electric cylinder 82 is movably installed on the outer circumferential surface of the rotating shaft tube 55, and the piston rod of the second electric cylinder 82 is movably connected to the bottom of the ground penetrating radar 9. The ground penetrating radar 9 is lifted and lowered by the telescopic movement of the piston rod of the second electric cylinder 82, and the second X-shaped movable rod 81 provides stable support. It should be noted that the traveling component 3 includes a driving device and tires, and can perform actions such as traveling forward, backward, and turning in the pipeline 1. The traveling component 3, the rotating lens 7, and the ground penetrating radar 9 all adopt currently known and existing devices. Since they are not the key points to be considered in the technical solution claimed in this application, they will not be elaborated herein.
[0027] Similarly, the fixed seat 5 can be liftably installed on the traveling component 3 through the first lifting component 4. The first lifting component 4 is composed of a first X-shaped movable rod 41 and a first electric cylinder 42. The structures of the first X-shaped movable rod 41 and the second X-shaped movable rod 81 are the same. The fixed seat 5 is lifted and lowered by the telescopic movement of the piston rod of the first electric cylinder 42.
[0028] Based on the above solution, there is silt 2 at the bottom of part of the pipeline 1. To avoid the geological radar 9 from colliding with the bottom objects, an inclination sensor and a three-dimensional force sensor are installed at the bottom of the geological radar 9. When the movement trajectory of the geological radar 9 is about to hit the pipe wall, it can be detected by the sensors, so that the detection can be stopped in time. To improve the safety of using the geological radar 9, a shock-absorbing mechanism can be installed at the connection between the geological radar 9 and the second lifting component 8; due to the existence of the silt 2 at the bottom of the pipeline, the bottom area of the pipe cannot be detected. For this reason, a lamp holder 6 is provided on the end face of the fixed seat 5 extending along the axial direction of the pipeline 1. A rotating lens 7 is installed in the central area of the lamp holder 6 and several lighting lamps are installed in the rounded edge area. The rotating lens 7 can be independently controlled. When the lighting lamps are turned on and adjusted to an appropriate angle, the state of the pipeline 1 and the detection state can be observed in real time. By observing the specific state of the bottom of the pipeline 1 with the naked eye of the operator, when there is silt 2 at the bottom of the pipeline, the geological radar 9 can also be independently controlled to stop the detection in time.
[0029] To realize the rotational movement of the rotating shaft tube 55, we drive it through a driving motor 51. Specifically, the fixed seat 5 includes a support 501, the bottom of the support 501 is movably connected to the first X-shaped movable rod 41, the upper end of the support 501 is provided with a support cover 502, and a closed space is formed between the support 501 and the support cover 502 to prevent the harsh environment inside the pipeline from affecting the internal components. The driving motor 51 is rigidly connected and installed on the support 501 through bolts. The output shaft of the driving motor 51 is connected to the input shaft of the planetary reduction gearbox 52. A driving gear 53 is fixedly sleeved on the output shaft of the planetary reduction gearbox 52. A small bearing 504 is sleeved at the end of the output shaft of the planetary reduction gearbox 52. The outer ring of the small bearing 504 is fixedly installed on the driving motor bearing cover 503, and the driving motor bearing cover 503 is fixedly connected to the support cover 502. The driving gear 53 is meshed with a driven gear 54, and the driven gear 54 is fixedly sleeved on the outer circumferential surface of the rotating shaft tube 55. The rotating shaft tube 55 is movably sleeved on the outer circumferential surface of the central rotating shaft 56. The central rotating shaft 56 is rotatably installed in the support 501 through a large bearing 507; after the power of the driving motor 51 is decelerated and amplified by the planetary reduction gearbox 52, it is transmitted to the driving gear 53 and then to the driven gear 54, thereby driving the rotating shaft tube 55 to rotate.
[0030] In order to achieve the independent rotational control of the rotating lens 7, a hollow slip ring 506 is sleeved on the outer circumferential surface of the central rotating shaft 56. The end of the central rotating shaft 56 extends outside the support 501 and is fixedly connected to the lamp holder 6. The driving of the central rotating shaft 56 to rotate is achieved through the hollow slip ring 506, thereby realizing the independent rotation of the rotating lens 7. In this embodiment, the outer ring of the large bearing 507 is fixed on the large bearing cover 509, the large bearing cover 509 is fixedly connected to the support 501, and an oil seal 508 is installed between the large bearing cover 509 and the central rotating shaft 56 to prevent the lubricating oil from flowing out. In addition, in order to limit the axial movement and the rotation angle of the central rotating shaft 56, a positioning block 510 is installed at the end face of the support 501 corresponding to the central rotating shaft 56. The maximum rotation angle of the central rotating shaft 56 is limited by the positioning block 510, and a snap ring 505 is sleeved on the outer circumferential surface of the central rotating shaft 56 to limit its axial movement.
[0031] In addition, since both the rotating shaft tube 55 and the central rotating shaft 56 are in a rotating state, in order to facilitate the arrangement of the internal cables, both the hollow slip ring 506 and the rotating shaft tube 55 are of a hollow structure, and a cable can be passed through the inside to ensure that the continuously rotating cable will not be wound and broken.
