Description

Technical Field

[0001] This utility model belongs to the field of substation line operation and maintenance technology, and specifically relates to a line foreign object removal device. Background Technology

[0002] Substations are critical facilities in power systems for voltage conversion and power distribution, with their incoming and outgoing lines typically connected by high-voltage overhead lines. In outdoor environments, these lines are susceptible to external influences, often becoming entangled or attached to foreign objects such as plastic bags, kites, and tree branches. These objects can not only cause line discharges and phase-to-phase short circuits, affecting power supply reliability, but also accelerate the aging of cable insulation, threatening the safe and stable operation of the power grid. Therefore, timely and effective removal of foreign objects from lines is an important aspect of substation operation and maintenance. Currently, foreign object removal from substation lines usually relies on personnel using cleaning tools on the ground. However, due to the diverse types and characteristics of foreign objects on the lines (such as soft plastic films and tough tree branches), and the often limited functionality of the cleaning blades at the tips of these tools, their adaptability to different types of foreign objects is insufficient, resulting in low cleaning efficiency. Furthermore, due to the long working distance and poor viewing angle, operators on the ground find it difficult to accurately observe and judge the relative position of the foreign object and the cleaning blade, frequently requiring repeated adjustments to the tool's posture and cutting position, which not only increases the difficulty and labor intensity of the operation but also increases safety risks. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a foreign object removal device for electrical circuits, which facilitates the disassembly and replacement of the cutting tools and allows for real-time observation of foreign objects on the circuits during the removal process.

[0004] This utility model discloses a foreign object removal device for electrical circuits, comprising: a telescopic rod, a display screen assembly, a connecting block, a cutting tool, and a limiting assembly. One end of the telescopic rod has a handle. The display screen assembly is mounted on the telescopic rod and close to the handle. The connecting block is located at the end of the telescopic rod furthest from the handle. The connecting block includes a insertion slot, a limiting hole, and a camera.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Figure 1 This is a three-dimensional structural diagram of a line foreign object cleaning device provided in this embodiment. Figure 2 This is a schematic diagram of a limiting component provided in this embodiment. Figure 3 This is a schematic diagram of the structure of a display screen assembly provided in this embodiment. Figure 4 This is a partial cross-sectional view of a connecting block provided in this embodiment.

[0022] like Figure 1 and Figure 2As shown, the foreign object removal device for electrical circuits of this utility model includes: a telescopic rod 1, a display screen assembly 2, a connecting block 3, a cutter 4, and a limiting component 5. One end of the telescopic rod 1 has a handheld part 6. The display screen assembly 2 is mounted on the telescopic rod 1 and is close to the handheld part 6. The connecting block 3 is located at the end of the telescopic rod 1 away from the handheld part 6. The connecting block 3 includes a insertion groove 31, a limiting hole 32, and a camera 33. The limiting hole 32 extends from the surface of the connecting block 3 to the side wall of the insertion groove 31. The camera 33 is electrically connected to the display screen assembly 2. The cutter 4 includes an interconnected insertion block 41 and a cutting part 42. The insertion block 41 has a connecting hole. The insertion block 41 is inserted into the insertion groove 31, and the connecting hole is aligned with the limiting hole 32. The cutting part 41 is used to remove foreign objects. The limiting component 5 is inserted into the connecting hole through the limiting hole 32 to fix the cutter 4 in the insertion groove 31.

[0023] The foreign object removal device in this embodiment can raise the blade 4 to the working height by adjusting the length of the telescopic rod 1. During operation, the camera 33 can capture real-time images of the position of the foreign object and the blade 4, which are displayed on the display screen assembly 2 on the telescopic rod 1. This allows the operator to clearly observe the operation from the ground, thereby accurately adjusting the working posture and cutting position of the blade 4 to achieve accurate and rapid removal of foreign objects, effectively reducing operational difficulty, labor intensity, and safety risks. In addition, the blade 4 of this device is connected to the connector 3 through the insertion block 41, the insertion slot 31, and the limiting assembly 5. This method has the advantages of stable connection and convenient assembly and disassembly, and the corresponding blade can be quickly replaced according to the type of foreign object, significantly improving operational adaptability and efficiency.

[0024] Among them, such as Figure 2 As shown, the limiting assembly 5 includes: a limiting baffle 51, a limiting rod 52, a retaining ring 53, and a return spring 54. The limiting baffle 51 is disposed at the end of the limiting hole 32 away from the insertion slot 31. The limiting rod 52 is movably disposed in the limiting hole 32. The retaining ring 53 is disposed on the side of the limiting rod 52 and can move with the limiting rod 52 in the limiting hole 32. The return spring 54 is sleeved on the limiting rod 52 and is connected between the limiting baffle 51 and the retaining ring 53. Under the pushing force of the return spring 54, the end of the limiting rod 52 facing the insertion slot 31 is inserted into the connecting hole, and the retaining ring 53 abuts against the surface of the insertion block 41.

[0025] It should be noted that in other embodiments, in order to more stably fix the tool 4 in the insertion slot 31, a limiting hole 32 can be provided on both sides (adjacent or opposite) of the insertion slot 31. Simultaneously, a connecting hole is provided on both sides (adjacent or opposite) of the insertion block 41. A limiting component 5 of this embodiment is provided in each limiting hole 32, and the limiting rod 52 of each limiting component 5 is inserted into a corresponding connecting hole through a limiting hole 32 to achieve positioning of both sides of the tool 4. In practical applications, the setting positions of the limiting holes 32 and connecting holes, as well as the number of limiting components 5 used, can be set according to the type of tool 4 and the workload; this embodiment does not impose excessive restrictions on this.

[0026] When the foreign object removal device of this embodiment needs to replace the blade 4, pull the limiting rod 52 towards the limiting baffle 51 to compress the return spring 54 until the end of the limiting rod 52 facing the insertion slot 31 is pulled out of the connection hole, thus releasing the lock between the insertion block 41 and the insertion slot 31, and then removing the blade 4 from the insertion slot 31. Then, insert the insertion block 41 of the new blade 4 into the insertion slot 31 (note that when inserting, the side of the insertion block 41 with the connection hole should correspond to the side of the insertion slot 31 with the limiting hole 32); then release the limiting rod 52, the return spring 54 returns to its original position, and the limiting rod 52 is inserted into the connection hole on the insertion block 41. The foreign object removal device of this embodiment allows for convenient and quick replacement of the blade 4, is easy and flexible to use, and has a wider range of applications. In addition, in this embodiment, a retaining ring 53 is provided on the limiting rod 52. When the plug block 41 is fixed in the plug groove 31, the retaining ring 53 abuts against the surface of the plug block 41. This arrangement can increase the contact area between the plug block 41 and the limiting rod 52, prevent the plug block 41 from twisting, and have a better limiting effect, making the connection between the tool 4 and the connecting block 3 more stable, so as to better carry out foreign matter cleaning operations.

[0027] Among them, such as Figure 2 As shown, a mounting plate 55 is provided at one end of the limiting rod 52 near the limiting baffle 51. The mounting plate 55 is provided with a pull handle 56.

[0028] like Figure 2 As shown, the two ends of the pull handle 56 in this embodiment are respectively connected to the surface of the mounting plate 55. A retaining ring is fitted on each side of the pull handle 56. The retaining ring is connected between the surface of the mounting plate 55 and the outer wall of the pull handle 56. This arrangement increases the connection area between the pull handle 56 and the mounting plate 55, thereby increasing the strength of the connection and preventing breakage or even detachment of the pull handle 56 during prolonged use, thus increasing the durability of the device.

[0029] In this embodiment, a mounting plate 55 is provided at the end of the limiting rod 52 near the limiting baffle 51. The diameter of the mounting plate 55 is larger than the diameter of the limiting hole 32, thus serving as a limiting device to prevent the limiting rod 52 from falling into the insertion slot 31 under the action of the return spring 54 after the tool 4 is removed from the insertion slot 31. In addition, this embodiment has a pull handle 56 on the mounting plate 55 to facilitate pulling the limiting rod 52 outward, which is beneficial for convenient and quick loading and unloading of the tool 4.

[0030] Among them, such as Figure 3 As shown, the display assembly 2 includes a mounting block 21, a fixing block 22, and a display 23. The mounting block 21 is sleeved on the telescopic rod 1. The fixing block 22 is connected to the mounting block 21. A mounting groove 24 is provided on the side of the fixing block 22 away from the mounting block 21. The display 23 is disposed in the mounting groove 24. The camera 33 is electrically connected to the display 23.

[0031] In this embodiment, the display assembly 2 uses the mounting block 21 to firmly connect the fixing block 22 to the telescopic rod 1, and the display 23 is placed in the mounting groove 24 on the fixing block 22. This not only makes it convenient for operators to view the image on the display 23, but also prevents the display 23 from being accidentally bumped, which helps to extend the service life of the display 23.

[0032] Among them, such as Figure 3 As shown, the display assembly 2 also includes a protective plate 25. The protective plate 25 is closable and disposed on the opening of the mounting slot 24 to cover the display 23 within the mounting slot 24. The protective plate 25 is provided with an auxiliary handle 26.

[0033] like Figure 3 As shown, a slide rail is provided along the inner wall of the mounting groove 24 on the open side of the mounting groove 24, extending to the side of the fixing block 22; the protective plate 25 is slidably inserted into the slide rail from the side of the fixing block 22 to close the opening of the mounting groove 24 and protect the display 23 inside. The protective plate 25 can be removed and installed by moving the protective plate 25 left and right along the extension direction of the slide rail using the auxiliary handle 26.

[0034] However, it should be noted that in other embodiments, it can also be designed such that: one side of the protective plate 25 is hinged to one side edge of the mounting groove 24, and the protective plate 25 can be opened and closed by pulling the protective plate 25 around the hinge axis through the auxiliary handle 26.

[0035] like Figure 3 As shown, the protective plate 25 has a protrusion, and the auxiliary handle 26 is hinged to the protrusion. This arrangement provides a good force-bearing position for the protective plate 25 when the auxiliary handle 26 is pulled, preventing damage to the protective plate 25 and preventing the auxiliary handle 26 from falling off.

[0036] In this embodiment, a protective plate 25 is provided on the opening of the mounting slot 24 to protect the display 23. When not in use, the protective plate 25 can be closed to protect the display 23 from scratches and damage.

[0037] Among them, such as Figure 4 As shown, the camera 33 is covered by a protective case 34. The protective case 34 is made of transparent material.

[0038] In this embodiment, a protective shell 34 covers the camera 33, providing reliable protection for the camera 33, preventing it from being impacted, and extending its service life. At the same time, the protective shell 34 is made of transparent material and will not affect the image captured by the camera 33.

[0039] Among them, such as Figure 1 As shown, the handheld part 6 includes: a sponge sleeve 61 and an anti-slip sleeve 62. The sponge sleeve 61 is fitted onto the telescopic rod 1. The anti-slip sleeve 62 wraps around the outer periphery of the sponge sleeve 61.

[0040] The handheld part 6 in this embodiment includes a sponge sleeve 61 and an anti-slip sleeve 62. The sponge sleeve 61 can improve the comfort of the operator gripping the telescopic rod 1, and the anti-slip sleeve 62 can improve the firmness of the grip, prevent slippage, and increase the safety during use.

[0041] Among them, such as Figure 1 As shown, the telescopic rod 1 includes a first sleeve 11, a second sleeve 12, and a third sleeve 13. The first sleeve 11 is telescopically disposed within the second sleeve 12. The second sleeve 12 is telescopically disposed within the third sleeve 13. A connecting block 3 is installed at the free end of the first sleeve 11. A handheld part 6 and a display screen assembly 2 are disposed on the third sleeve 13.

[0042] The telescopic rod 1 in this implementation is designed as a three-stage telescopic cylinder structure, which can meet the length requirements while ensuring the structural strength of the telescopic rod 1.

[0043] Among them, such as Figure 4 As shown, the first sleeve 11 also includes a retaining ring 14. The retaining ring 14 is sleeved on the first sleeve 11 and connected between the outer wall of the first sleeve 11 and the bottom of the connecting block 3.

[0044] In this embodiment, a fixing ring 14 is provided between the outer wall of the first sleeve 11 and the bottom of the connecting block 3, which increases the connection area between the first sleeve 11 and the connecting block 3, thereby improving the firmness of the connection between the first sleeve 11 and the connecting block 3, preventing the connection between the first sleeve 11 and the connecting block 3 from loosening after long-term use, and extending the service life.

[0045] Among them, see Figure 1The cutting part 42 is at least one of a hook knife, a serrated knife, a rotary cutter, and a scraper.

[0046] Specifically, for soft, tangled foreign objects, a hook knife can be used to scrape or cut the soft foreign object wrapped around the wire, such as... Figure 1 The cutting tool shown has a hook-shaped cutting section. For hard, branch-like foreign objects, serrated blades and rotary cutters can be used to cut them. For mud and sand adhering to cables, a scraper can be used for cleaning.

[0047] In other embodiments, the cutting section 42 may also adopt a combined structure, for example, one side is a hook knife and the other side is a saw knife, and the side is also equipped with a scraper, so as to realize multiple uses of one knife. Operators do not need to frequently change the knife to deal with various foreign objects, thereby improving work efficiency and reducing equipment load.

[0048] The structure of the line foreign object removal device has been introduced above. Next, we will introduce how to use the line foreign object removal device: First, connect the power to the camera 33 and the monitor 23. The handheld part 6 at the end of the telescopic rod 1 has an anti-slip sleeve 62 designed to ensure a firm grip. After moving the telescopic rod 1 to a suitable working position, extend it to the required length, causing the connecting block 3 and the blade 4 at the front end to extend to the vicinity of the foreign object.

[0049] Then, pull the auxiliary handle 26 to open the protective plate 25 and activate the camera 33 and monitor 23. By observing the real-time footage captured by the camera 33 on the monitor 23, the operator can clearly grasp the relative position of the knife and the foreign object 4 on the ground, and then fine-tune the telescopic rod 1 to accurately align the knife 4 with the foreign object.

[0050] After alignment, the foreign object can be cut using the blade 4 by pushing, pulling, or rotating the telescopic rod 1. The protective shell 34 on the outside of the camera 33 can effectively prevent falling foreign objects from damaging the camera 33.

[0051] When it is necessary to change tool 4 to deal with different types of foreign objects, the procedure is as follows: By pulling the handle 56, the limiting rod 52 is disengaged from the connecting hole on the plug block 41, and the original cutting tool 4 can be removed from the connecting block 3.

[0052] Then insert the new tool 4's insertion block 41 into the insertion slot 31 and release the pull handle 56. The return force of the reset spring 54 can push the limit rod 52 to re-insert into the connection hole on the new tool 4 corresponding to the limit hole 32, thus completing the locking.

[0053] The tool changing process is simple and quick, and the connection is stable and reliable, significantly improving the adaptability and practicality of cleaning operations.

[0054] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
