Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a communication transmission line inspection device. Background Technology

[0002] A transmission line is a line in a communication network that connects the nodes, serving as a bridge for data transmission between them. A communication network consists of a certain number of nodes and transmission lines connecting them, forming a communication system to enable information transmission between two or more designated points. Transmission lines include communication cables, optical fibers, and fiber optic cables.

[0003] In the existing technology, in order to maintain the safe operation of communication transmission lines and avoid damage to the lines, it is usually necessary for staff to conduct regular inspections of the communication transmission lines, and inspection devices are also used to inspect the communication transmission lines.

[0004] For example, patent document CN106911102B discloses a fiber optic cable line inspection tool, including an overhead track, a mobile trolley mounted on the overhead track, an inspection robot mounted on the mobile trolley, and a control center connected to the inspection robot. The inspection robot is equipped with a bird detection module, a visual inspection module, a bird repulsion module, a bird nest removal module, a control module, and a communication module. The bird nest removal module includes a bird nest removal mechanism and a bird nest storage mechanism. The control module is signal-connected to the mobile trolley, bird detection module, visual inspection module, bird repulsion module, bird nest removal module, and communication module. This invention uses an inspection robot to repel birds on or along fiber optic cable lines, preventing birds from roosting on power cables and causing damage to the power transmission network. Furthermore, the inspection robot's built-in bird nest removal mechanism can remove bird nests from poles or lines, protecting the safety of chicks if they are present.

[0005] Based on the above search and combined with existing technology, it was found that most existing inspection devices are designed for ground or air communication transmission lines (such as power optical cables). However, a considerable portion of existing communication transmission lines include communication cables and optical cables buried in underground pipelines. Existing technologies usually rely on manually opening maintenance manholes for inspection, which is not only labor-intensive and time-consuming, but also makes it difficult to detect non-broken line damage in areas other than maintenance manholes. The inspection work is not comprehensive enough. Therefore, a communication transmission line inspection device is needed. Utility Model Content

[0031] 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.

[0032] Example: Reference Figure 1-3 The communication transmission line inspection device shown includes a main mounting half-ring 1 and a closing ring mounting body 2. The main mounting half-ring 1 and the closing ring mounting body 2 are detachably fixed by a connector. Both the main mounting half-ring 1 and the closing ring mounting body 2 are semi-circular rings, and after the main mounting half-ring 1 and the closing ring mounting body 2 are connected, they form a circular ring that is movably fitted on the communication transmission line.

[0033] At least two auxiliary walking wheel sets 3 are fixed on the outside of the main mounting half ring 1, and at least one main walking wheel set 4 is fixed on the outside of the closed ring mounting body 2. The main walking wheel set 4 is electrically driven. The walking wheels 19 of both the auxiliary walking wheel set 3 and the main walking wheel set 4 are in rolling contact with the inner wall of the pipeline where the communication transmission line is located. The auxiliary walking wheel set 3 and the main walking wheel set 4 cooperate to support the circular ring body formed by the main mounting half ring 1 and the closed ring mounting body 2.

[0034] Several detection contacts 11 that are in contact with the surface of the communication transmission line are installed on the inner side of the main mounting half-ring 1. A remote communication module 8 for uploading the detection data of the detection contacts 11 to the remote terminal is also installed on one side of the main mounting half-ring 1.

[0035] One side of the ring mounting body 2 is fixed with the main power supply battery pack 5, which supplies power to the main walking wheel assembly 4, the remote communication module 8, and the detection contact 11.

[0036] Based on the above structure, when it is necessary to inspect communication transmission lines buried in underground pipelines, the staff only needs to place the communication transmission line inspection device in the maintenance well and connect the main installation half-ring 1 and the closing ring installation body 2, so that the ring body formed by the main installation half-ring 1 and the closing ring installation body 2 is fitted on the communication transmission line to be inspected, and the detection contact 11 makes active contact with the outer surface of the communication transmission line. At this time, the main walking wheel set 4 is started to move by electric drive, and the main walking wheel set 4, together with the auxiliary walking wheel set 3, can drive the entire device to move in the pipeline, and inspect the communication transmission line through the detection contact 11. During the movement, the detection contact 11 uploads the detection data to the remote terminal through the remote communication module 8, thereby completing the inspection of the communication transmission line. This not only avoids the disadvantages of large workload and long inspection cycle of manual inspection, but also makes the inspection more comprehensive. For non-broken line damage in non-maintenance wells, the specific damage status and location can be found through inspection, so as to carry out subsequent maintenance work in a timely manner and achieve better inspection results.

[0037] Furthermore, a support rod 12 is fixed to the side of the detection contact 11 near the main mounting half ring 1, and a sliding hole 14 is opened on the inner side of the main mounting half ring 1, with one end of the support rod 12 slidably connected in the sliding hole 14.

[0038] A first spring 13 is movably sleeved on the outside of the support rod 12. The two ends of the first spring 13 are fixed to one side of the detection contact 11 and the inside of the main mounting half ring 1, respectively.

[0039] With the support rod 12 and the first spring 13, when the surface of the communication transmission line is uneven (such as unevenness caused by damage or dirt on the surface), the detection contact 11 can move with the extension and retraction of the support rod 12, and can always fit against the surface of the communication transmission line through the elastic force of the first spring 13. This not only enables stable detection of the communication transmission line, but also avoids the situation where the detection contact 11 is obstructed and cannot move, making the communication transmission line inspection device more practical.

[0040] Furthermore, the auxiliary travel wheel set 3 and the main travel wheel set 4 have the same structure, and the main travel wheel set 4 includes:

[0041] Mounting sleeve 15, one end of mounting sleeve 15 is fixed to the outside of the ring mounting body 2 (the mounting sleeve 15 of the auxiliary walking wheel set 3 is fixed to the outside of the main mounting half ring 1), and the other end of mounting sleeve 15 has a mounting groove.

[0042] Mounting rod 16, one end of which is slidably connected to the mounting groove of mounting sleeve 15;

[0043] The second spring 17 has two ends fixed to the end of the mounting rod 16 located inside the mounting sleeve 15 and the bottom wall of the mounting groove of the mounting sleeve 15, respectively.

[0044] Wheel seat 18, the wheel seat 18 is fixed to the end of the mounting rod 16 away from the ring mounting body 2;

[0045] The traveling wheel 19 is rotatably connected to the wheel seat 18 via a rotating shaft.

[0046] By installing the sleeve 15, mounting rod 16, and second spring 17, the walking wheel 19 can extend and retract inside the pipe where the communication transmission line is laid, thereby adapting to pipes with different inner diameters, expanding the applicability of the communication transmission line inspection device, and improving the flexibility of the communication transmission line inspection device in actual use.

[0047] Furthermore, a micro motor 20 is fixed to one side of the wheel seat 18 of the main walking wheel set 4 via a fixing plate 22. The micro motor 20 is electrically connected to the main power supply battery pack 5. The output shaft end of the micro motor 20 is connected to the rotating shaft of the walking wheel 19 via a gearbox 21. The micro motor 20 drives the walking wheel 19 of the main walking wheel set 4 to walk, thereby cooperating with the walking wheel 19 of the auxiliary walking wheel set 3 to achieve the purpose of driving the entire device to walk in the pipeline.

[0048] Furthermore, the connector includes a connecting plate 6 and connecting bolts 7. Multiple connecting plates 6 are provided and are respectively fixed to both ends of the main mounting half ring 1 and both ends of the closing ring mounting body 2. The connecting bolts 7 are used to connect two connecting plates 6 that are close to each other at the ends of the main mounting half ring 1 and the closing ring mounting body 2, thereby realizing the detachable fixing of the main mounting half ring 1 and the closing ring mounting body 2, which makes it easy to put the device on the communication transmission line and to install and disassemble the communication transmission line inspection device.

[0049] Furthermore, an image acquisition module 9 for collecting image information of the communication transmission line is also fixed on one side of the main installation semi-ring 1. The image acquisition module 9 transmits the collected image information to the remote terminal through the remote communication module 8. The image acquisition module 9 is electrically connected to the main power supply battery pack 5. The image acquisition module 9 can work with the detection contact 11 to achieve more comprehensive detection, that is, it can realize the combined observation of image and detection data, which makes it easier to obtain more accurate inspection results.

[0050] A backup battery pack 10 is also fixed on the side of the ring mounting body 2 away from the main power supply battery pack 5. The backup battery pack 10 is electrically connected to the remote communication module 8, the image acquisition module 9, the detection contact 11, and the micro motor 20. The backup battery pack 10 can provide the device with a higher endurance and can also prevent the device from losing its inspection capability due to the main power supply battery pack 5 failing to provide power, thus improving the reliability of the device to a certain extent.

[0051] It should be noted that the detection contact 11, remote communication module 8, remote terminal and image acquisition module 9 proposed in this device all adopt commonly used components or devices in the prior art that are suitable for this embodiment, such as infrared sensors, resistance sensors, WiFi communication modules, remote monitoring terminals, infrared cameras, etc., in order to achieve the desired effect of this application.

[0052] The working principle of this utility model is as follows: In daily use, when it is necessary to inspect communication transmission lines buried in underground pipelines, the staff only needs to place the communication transmission line inspection device in the maintenance well and connect the main mounting half-ring 1 and the closing ring mounting body 2, so that the ring body formed by the main mounting half-ring 1 and the closing ring mounting body 2 is fitted onto the communication transmission line to be inspected, and the detection contact 11 makes active contact with the outer surface of the communication transmission line. At this time, it is only necessary to start the micro motor 20 to drive the main walking wheel set 4 to move, so that the main walking wheel set 4, together with the auxiliary walking wheel set 3, can drive the entire device to move in the pipeline, and detect the communication line through the detection contact 11. During the inspection of the transmission line, the detection contact 11 uploads the detection data to the remote terminal via the remote communication module 8, thereby completing the inspection of the communication transmission line. At the same time, the image acquisition module 9 can work with the detection contact 11 to achieve a more comprehensive inspection, that is, to achieve the combined observation of images and detection data, so as to obtain more accurate inspection results. This not only avoids the disadvantages of large workload and long inspection cycle of manual inspection, but also makes the inspection more comprehensive. For non-breakage damage in non-maintenance wells, the specific damage status and location can be found through inspection, so as to carry out subsequent maintenance work in a timely manner and achieve better inspection results.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
