[0016] 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. Example

[0017] Please see Figure 1-5 The present invention provides the following technical solution: a live cleaning device for railway contact wire insulators, including a connecting hose 1, one end of the connecting hose 1 is connected to a nozzle 4, an adjustment component 3 is installed at the bottom of the connecting hose 1, and a handheld component 2 is fixed to the outer surface of the adjustment component 3. The handheld component 2 includes an extension rod 21, which is fixedly installed in the middle of the outer surface of the adjusting component 3. An insertion hole 27 is provided on the outer surface of the extension rod 21. A storage rod 26 is sleeved on the outer end of the extension rod 21. A fixing block 23 is fixedly connected to the outer surface of the storage rod 26. A pull rod 22 is movably arranged inside the fixing block 23. A pin block 24 is fixedly connected to the bottom of the pull rod 22. A spring 25 is sleeved on the surface of the pull rod 22.

[0018] By adopting the above technical solution, when it is necessary to adjust the length of the handheld lever, first pull the lever 22. The lever 22 will drive the pin block 24 to disengage from the insertion hole 27 inside the extension rod 21. At this time, the spring 25 will be compressed, pulling the extension rod 21 outward until the appropriate length is reached. Then, pull the lever 22 out, and the pin block 24 will be inserted into the insertion hole 27 under the action of the spring 25. The insertion rod at the bottom of the pin block 24 can fix the position of the two, thereby completing the adjustment of the length of the handheld lever and making the device more flexible to use.

[0019] Specifically, the storage rod 26 has a through hole on the outer side near the pin block 24, the pin block 24 has protrusions fixed to both sides of the surface, and the fixing block 23 has a limit groove on the inner side.

[0020] By adopting the above technical solution, the through hole allows the insertion rod at the bottom of the pin block 24 to be directly inserted into the insertion hole 27 inside the extension rod 21. When the pin block 24 moves, the movement of the protrusion inside the limiting groove can improve the stability of the pin block 24.

[0021] Specifically, one end of the extension rod 21 is fixed to a mounting plate, and the inner side of the mounting plate is provided with fixing bolts.

[0022] By adopting the above technical solution, the extension rod 21 and the adjustment component 3 can be easily installed and fixed by the mounting plate, which improves the stability between the two, and the installation efficiency is improved by fixing bolts.

[0023] Specifically, the end of the storage rod 26 away from the extension rod 21 is provided with a handle, and the surface of the handle is fitted with a rubber sleeve.

[0024] By adopting the above technical solution and setting a handle covered with a rubber sleeve, the device can be easily held by technicians, while also optimizing the user experience.

[0025] In this embodiment, when the length of the handheld lever needs to be adjusted, first pull the lever 22. The lever 22 causes the pin block 24 to disengage from the insertion hole 27 inside the extension rod 21. At this time, the spring 25 contracts under force, pulling the extension rod 21 outwards to the appropriate length. Then, release the lever 22. The pin block 24, under the action of the spring 25, inserts into the insertion hole 27. The insertion rod at the bottom of the pin block 24 fixes the position of the two, thus completing the length adjustment of the handheld lever. The device is more flexible to use. The through hole allows the rod at the bottom of the pin block 24 to be directly inserted into the insertion hole 27 inside the extension rod 21. When the pin block 24 moves, the movement of the protrusion inside the limiting groove can improve the stability of the pin block 24. The mounting plate can facilitate the installation and fixing of the extension rod 21 and the adjustment component 3, improving the stability between the two. The fixing bolts improve the installation efficiency. The handle with a rubber sleeve makes it easy for technicians to hold the device, while also optimizing the user experience. Example

[0026] The difference between this embodiment and embodiment 1 is that, specifically, the adjustment component 3 includes a fixing frame 31, which is located at the bottom of the nozzle 4. A drive motor 34 is mounted on one side surface of the fixing frame 31. A protective shell 35 is fixedly mounted on the outside of the drive motor 34. A bidirectional screw 33 is connected to the output end of the drive motor 34. A threaded plate 36 is threadedly connected to the surface of the bidirectional screw 33. A connecting block 32 is fixedly connected to the inner side of the threaded plate 36. A cleaning component 37 is mounted on one side surface of the threaded plate 36.

[0027] By adopting the above technical solution, when using the adjustment component 3, if it is necessary to adjust the distance between the nozzles 4, the drive motor 34 is started. The drive motor 34 drives the bidirectional screw 33 to rotate, and the threaded plate 36 further drives the connecting block 32 and the nozzles 4 to adjust their positions. After the adjustment is completed, the external cleaning fluid pipeline is connected to the connecting hose 1 to start the cleaning work of the insulator. When the cleaning effect is not good, the insulator can be further cleaned by the cleaning component 37, thereby ensuring the cleaning effect of the device.

[0028] Specifically, the cleaning component 37 includes a support frame 371, which is fixedly installed on one side of the threaded plate 36. A mounting bolt 372 is fixedly provided between the support frame 371 and the threaded plate 36. A cleaning motor 375 is installed on the top surface of the support frame 371. A drive shaft 373 is connected to the output end of the cleaning motor 375. A cleaning strip 374 is fixedly attached to the surface of the drive shaft 373.

[0029] By adopting the above technical solution, when using the cleaning component 37, the cleaning motor 375 is started, the cleaning motor 375 drives the drive shaft 373 to rotate, and the drive shaft 373 further drives the cleaning strip 374 to move on the surface of the insulator. By the continuous movement of the cleaning strip 374 on the surface of the insulator, other stains on the surface of the insulator can be cleaned, thereby improving the cleaning effect.

[0030] Specifically, a sliding groove is provided on the inner side of the fixing bracket 31, and a slider is fixedly connected to the inner side of the threaded plate 36.

[0031] By adopting the above technical solution, the threaded plate 36 moves synchronously inside the groove through the slider during movement, which improves the stability of the movement of the threaded plate 36.

[0032] In this embodiment, when using the adjustment component 3, if it is necessary to adjust the distance between the nozzles 4, the drive motor 34 is started. The drive motor 34 drives the bidirectional screw 33 to rotate, which in turn drives the connecting block 32 and the nozzles 4 to adjust their positions through the threaded plate 36. After the adjustment is completed, the external cleaning fluid pipeline is connected to the connecting hose 1 to start cleaning the insulator. If the cleaning effect is not good, the insulator can be further cleaned through the cleaning component 37, thereby ensuring the cleaning effect of the device. When using the cleaning component 37, the cleaning motor 375 is started, which drives the drive shaft 373 to rotate. The drive shaft 373 further drives the cleaning strip 374 to move on the surface of the insulator. The continuous movement of the cleaning strip 374 on the surface of the insulator can clean other stains on the surface of the insulator, improving the cleaning effect. When the threaded plate 36 moves, the slider moves synchronously inside the groove, which improves the stability of the movement of the threaded plate 36.

[0033] The structure and working principle of the connecting hose 1 and nozzle 4 in this utility model have been disclosed in a live cleaning device for railway contact wire insulators disclosed in Chinese Patent Publication No. CN222358889U.

[0034] The working principle and usage of this utility model are as follows: When the length of the handheld lever needs to be adjusted, first pull the lever 22. The lever 22 drives the pin block 24 upward to disengage from the insertion hole 27 inside the extension rod 21. At this time, the spring 25 is compressed, pulling the extension rod 21 outward to the appropriate length. Then, release the lever 22. Under the action of the spring 25, the pin block 24 inserts into the insertion hole 27. The insertion rod at the bottom of the pin block 24 can fix the position of the two, thereby completing the adjustment of the handheld lever length. This makes the device more flexible to use. The through hole allows the rod at the bottom of the pin block 24 to be directly inserted into the insertion hole 27 inside the extension rod 21. When the pin block 24 moves, the movement of the protrusion inside the limiting groove can improve the stability of the pin block 24. The mounting plate can facilitate the installation and fixing of the extension rod 21 and the adjustment component 3, improving the stability between the two. The fixing bolts improve the installation efficiency. The handle with a rubber sleeve makes it easy for technicians to hold the device, while also optimizing the user experience. When using the adjustment component 3, if it is necessary to adjust the distance between the nozzles 4, start the drive motor 34. The drive motor 34 drives the bidirectional screw 33 to rotate, which in turn drives the connecting block 32 and the nozzles 4 to adjust their positions through the threaded plate 36. After the adjustment is completed, connect the external cleaning fluid pipe to the connecting hose 1 to start cleaning the insulator. If the cleaning effect is not good, the insulator can be further cleaned through the cleaning component 37, thus ensuring the cleaning effect of the device. When using the cleaning component 37, start the cleaning motor 375. The cleaning motor 375 drives the drive shaft 373 to rotate, which in turn drives the cleaning strip 374 to move on the surface of the insulator. The continuous movement of the cleaning strip 374 on the surface of the insulator can clean other stains on the surface of the insulator, improving the cleaning effect. When the threaded plate 36 moves, the slider moves synchronously inside the groove, which improves the stability of the movement of the threaded plate 36.
