Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and in particular to a power cable detection device. Background Art

[0002] With the development of economy, the dependence on electric energy in various fields is increasing. As the cables are exposed to the outdoors for a long time, the damage problem of transmission line cables is becoming more and more serious, affecting the normal electricity consumption of users. Therefore, it is usually necessary to regularly detect the damage of cables. In the prior art, when using line loss detection equipment to detect electric wires, the detection equipment is usually used to detect the diameter of the wire to determine whether the line is damaged; however, when the existing detection equipment detects the diameter of the wire, the impurities attached to the wire are likely to affect the accuracy of the detection equipment on the wire detection, which leads to a certain deviation in the actual detection result.

[0003] In response to the above problems, a Chinese invention patent with authorization announcement number CN116773437B discloses a power transmission cable damage detection device. The application rolls on the wire through a pulley, and maintains the close contact state of the detection unit by setting a cam to compress the gas. At the same time, impurities attached to the wire are removed by blowing, thereby reducing the interference of impurities on the detection results, thereby improving the accuracy of the detection.

[0004] Although the above scheme can clean the debris on the wires to a certain extent by blowing air, some debris is attached relatively tightly, and the effect of cleaning the debris by blowing air alone is relatively general; and the damage detection device disclosed in the above scheme needs to be placed on two cables at the same time to be able to be positioned and moved stably, which has many restrictions when used; in addition, the above scheme completely relies on the detection unit to detect the cable diameter (the smoothness of the cable surface) to obtain the cable status result, and the data source is relatively single, and there is a lack of data support for directly determining the cable status as a basis for judgment.

[0005] Therefore, there is a need for a power cable detection device with accurate detection results, efficient and stable cleaning effects, the ability to move stably with only a single cable, and a variety of detection data sources. Summary of the invention

[0006] The embodiment of the present application provides a power cable detection device, which solves the technical problems in the prior art that the power transmission cable damage detection device has a relatively poor cleaning effect on the debris on the cable, requires multiple cables to move, and has a single source of detection data. The power cable detection device achieves the technical effects of accurate detection results, efficient and stable cleaning effects, stable movement with only a single cable, and diverse sources of detection data.

[0007] The embodiment of the present application provides a power cable detection device, including a front sleeve assembly and a rear sleeve assembly which are sleeved on the cable and move along the cable when in use, a carrying and containing box, a connecting plate assembly, a dragging and shifting assembly, and a camera assembly for recording cable images;

When the device of the present application is running, images of the top and bottom of the cable being detected are recorded as data support for cable detection.

[0083] For the convenience of description, the inner bladder body 131 of the front sleeve assembly 100 is defined as a front bladder, and the inner bladder body 131 on the rear sleeve assembly 200 is defined as a rear bladder.

[0084] The power assembly is used to provide power for the operation of the various components of the power cable detection device of the present application, and the control unit plays a role in controlling the coordinated operation of the various components of the power cable detection device. Both are prior arts and will not be described in detail here.

[0085] Preferably, the control unit is a combination of a programmable logic controller and a remote controller.

[0086] When the power cable detection device of the embodiment of the present application is used:

[0087] 1. First, adjust the position of the detection head 112 according to the specifications of the cable to be detected, and ensure that the detection head 112 can contact the side wall of the cable to be detected; put the front sleeve assembly 100 and the rear sleeve assembly 200 on the cable to be detected; operate the camera assembly 600;

[0088] 2. Then control the clamping rotating wheel 122 to rotate and drive the entire device to slide on the cable; while sliding, use the detection head 112 to detect the cable in real time;

[0089] 3. If the cable is not smooth enough (i.e., there may be debris or damage) during the inspection process, the rear capsule is controlled to expand first to fix the rear sleeve assembly 200 on the cable; then the airbag is controlled to expand and contact the side wall of the cable; thereafter, the drag displacement assembly is controlled to operate so that the front sleeve assembly 100 moves backward and the side wall of the cable is wiped (erased) to clean and remove any debris that may exist;

[0090] 4. Then control the drag-shift assembly to run again, reset the front sleeve assembly 100, and use the detection head 112 to perform a second detection on the same section of the cable at the same time to ensure the accuracy of the detection (if an abnormality is still detected, the result can be recorded or erased again);

[0091] 5. Control the entire device to continue moving and detecting.

[0092] Preferably, during the detection, the anterior capsule and the posterior capsule can be controlled to frequently expand and contract to shake off adhered debris.

[0096] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0097] The present invention solves the technical problems in the prior art that the cleaning effect of debris on the cable by the power transmission cable damage detection device is relatively poor, the movement requires the support of multiple cables, and the detection data source is single.

[0101] When the sliding adsorption strip 135 moves, the built-in soft strip 136 is driven to move by magnetic force.

[0102] During the operation of the device of the present application, the position of the built-in soft strip 136 can be controlled by the sliding adsorption strip 135, and the use and wear of the outer cleaning sheet 137 can be concentrated in one place (that is, the use of the outer cleaning sheet 137 is focused) by controlling the expansion of the built-in soft strip 136 and propping up part of the inner bag 131. After using the same part of the outer cleaning sheet 137 for many times, the focus use position can be changed to ensure the cleaning effect while ensuring the service life of the outer cleaning sheet 137.

[0103] Preferably, Figure 8 As shown, the outer cleaning sheet 137 is composed of multiple pieces of cloth spliced ​​together, and different pieces of cloth have different materials and different scrubbing effects.
