Description

Technical Field

[0001] This utility model relates to the technical field of foreign object removal devices, specifically a foreign object removal device for circuit testing. Background Technology

[0002] The power distribution network consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. It plays an important role in distributing electrical energy in the power grid. Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line poles, conductors, insulators, line hardware, guy wires, pole foundations, grounding devices, etc., and are erected on the ground. Before testing, foreign objects on the surface of power distribution network transmission lines usually need to be removed.

[0003] Chinese utility model CN220692695U describes a tool for removing foreign objects from power distribution lines. It includes an adjustable structure for the tool, which works by using a slider and a horizontal plate to adjust the position of the scraper on the horizontal plate. Once the tool is adjusted to the appropriate position, the bolt is rotated to tighten the slider and stabilize the position of the clamping plate.

[0004] However, existing devices require tools to rotate the bolts, which is cumbersome, and the bolt's position on the horizontal plate is fixed, limiting the slider's ability to only move to the bolt's location for adjustment. Therefore, a more easily adjustable foreign matter removal device was designed to address these issues. Utility Model Content

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0031] The power distribution network consists of overhead lines, cables, poles, distribution transformers, disconnect switches, reactive power compensators, and some auxiliary facilities. It plays an important role in distributing electrical energy in the power grid. Transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line poles, conductors, insulators, line hardware, guy wires, pole foundations, grounding devices, etc., and are erected on the ground. Before testing, foreign objects on the surface of power distribution network transmission lines usually need to be removed.

[0032] In related technologies, the position of the scraper on the horizontal plate can be adjusted by using a sliding connection between a slider and a horizontal plate. After adjusting to the appropriate position, only the bolt needs to be turned to tighten the slider and stabilize the position of the clamping plate. However, the existing device requires tools to turn the bolt, which is cumbersome, and the position of the bolt on the horizontal plate is fixed. The slider can only be moved to the position of the bolt for fixed adjustment, which is quite limiting.

[0033] To address some of the problems in related technologies, this application provides a foreign matter removal device for circuit testing. When cleaning the outer wall of the circuit, the spacing of the clamping plates 13 needs to be adjusted first. At this time, the pull rod 26 can be pulled to retract the insertion rod 25 into the groove 23. During the retraction, the spring 24 will be compressed, and one end of the insertion rod 25 will disengage from the positioning hole 22, releasing the restriction on the slider 12. Then, the pull rod 26 can be pushed to allow the slider 12 to slide and adjust its position inside the horizontal plate 11. After adjusting to the appropriate position, the pull rod 26 can be released, and the spring 24 will rebound to push the insertion rod 25 out of the groove 23 and insert it into the positioning hole 22 to fix the position of the slider 12. Finally, the circuit is passed through the inner side of the clamping plate 13, and the horizontal plate 11 is dragged to move the clamping plate 13 so that it slides on the outer wall of the circuit, which can clean the impurities on the outer wall of the circuit.

[0034] This application is described below with reference to the accompanying drawings and specific embodiments:

[0035] This application provides a foreign object removal device for circuit testing, comprising: a horizontal plate 11 with a slider 12 slidably disposed inside it; a clamping plate 13 disposed at the bottom of the slider 12; an adjustment component 2 disposed inside the slider 12, the adjustment component 2 comprising: a housing 21 disposed at the bottom of the slider 12 and its bottom end connected to the clamping plate 13; a positioning hole 22 formed in the inner side wall of the horizontal plate 11; a groove 23 formed in the outer side wall of the slider 12; a spring 24 disposed inside the groove 23; one end of a plug rod 25 inserted into the groove 23 and connected to the spring 24; and one end of a pull rod 26 passing through the slider 12 and inserted into the groove 23 and connected to the plug rod 25.

[0036] When cleaning the outer wall of the circuit, first adjust the spacing of the clamping plates 13. Then, pull the lever 26 to retract the insert rod 25 into the groove 23. During the retraction, the spring 24 will be compressed, and one end of the insert rod 25 will disengage from the positioning hole 22, releasing the restriction on the slider 12. Then, push the lever 26 to allow the slider 12 to slide and adjust its position inside the horizontal plate 11. After adjusting to the appropriate position, simply release the lever 26, and the spring 24 will rebound, pushing the insert rod 25 out of the groove 23 and inserting it into the positioning hole 22 to fix the position of the slider 12. Finally, pass the circuit through the inner side of the clamping plate 13 and drag the horizontal plate 11 to move the clamping plate 13 so that it slides on the outer wall of the circuit, which can clean the impurities on the outer wall of the circuit.

[0037] In some embodiments, the adjustment component 2 further includes a pull torque 27 disposed at one end of the pull rod 26.

[0038] The design of the pull knob 27 makes it easy to grip, and the pull rod 26 can be moved while pulling, which can also reduce the possibility of slipping.

[0039] In some embodiments, the adjustment component 2 further includes a cone 28 disposed at one end of the insert rod 25.

[0040] The pointed end of the cone 28 makes it easier to insert the rod 25 into the positioning hole 22 during use.

[0041] In some embodiments, the adjustment component 2 further includes a measuring ruler 29 disposed on the top of the horizontal plate 11.

[0042] The design of the measuring ruler 29 makes it easy to refer to and allows for more precise adjustment of the spacing between the clamps 13.

[0043] In some embodiments, a clamping assembly 3 is provided inside the housing 21. The clamping assembly 3 includes: a threaded rod 31 with one end inserted into the interior of the housing 21 and rotatably connected to the housing 21; a threaded block 32 slidably disposed inside the housing 21 and threadedly connected to the threaded rod 31 through it, with its bottom end connected to the clamping plate 13; and a knob 33 disposed at one end of the threaded rod 31.

[0044] When using it, when dealing with wires of different diameters, the screw rod 31 can be rotated by rotating the knob 33 and connected to the screw block 32. At this time, because the screw block 32 is slidably set inside the housing 21 and is restricted from rotating, the screw rod 31 will drive the two screw blocks 32 to move closer when it rotates, so that the two clamps 13 move closer and fit against the outer wall of the wire.

[0045] In some embodiments, the clamping assembly 3 further includes a protrusion 34 disposed on the inner sidewall of the clamping plate 13.

[0046] When in use, the design of the convex strip 34 can better scrape off impurities adhering to the outer wall of the circuit.

[0047] In some embodiments, the clamping assembly 3 further includes: one end of a threaded rod 35 passing through the threaded block 32 and connected to the clamping plate 13; and a nut 36 sleeved on the outer side wall of the threaded rod 35 and threadedly connected to the threaded rod 35.

[0048] When cleaning lines with large diameter differences, the cleaning effect can be improved by replacing the clamp plate 13. Simply rotate the nut 36 to disengage the nut 36 from the threaded rod 35, then remove the clamp plate 13 from the threaded block 32 and replace it with a new clamp plate 13. Insert the threaded rod 35 at the top of the clamp plate 13 through the threaded block 32 and then tighten it with the nut 36.

[0049] In some embodiments, the clamping assembly 3 further includes a connecting rod 37, one end of which passes through the threaded block 32 and is connected to the clamping plate 13.

[0050] When in use, the design of the connecting rod 37 can better restrict the rotation of the clamp 13, so that the clamp 13 remains stable.
