[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, not all embodiments.

[0024] The components described and shown in the drawings and embodiments of the present invention may be arranged and designed in various configurations. Therefore, the detailed description of the embodiments of the present invention provided in the following drawings is not intended to limit the scope of the claimed invention, but merely represents a selected embodiment of the present invention. Based on the drawings and embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] It should be noted that the terms "comprises", "includes" or any other variations are intended to cover non-exclusive inclusion, so that a process, element, method, article or equipment that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to the process, element, method, article or equipment.

[0026] The features and performances of the present invention are further described in detail below in conjunction with the embodiments.

[0027] Embodiment 1 according to Figure 1-Figure 4 The present invention discloses a cleaning device for operation and maintenance of power transmission lines, which specifically comprises: a supporting base 1, a movable base 5, and an upper top plate 6; a power supply 7 is connected and installed on the upper top plate 6, and an electric telescopic rod 8 is connected and installed on the lower end of the upper top plate 6, and the lower end of the electric telescopic rod 8 is installed on the movable base 5.

[0028] The upper top plate 6 is arranged above the supporting base 1. Figure 3 As shown, a plurality of cleaning blocks 9 and a plurality of clamping plates 10 are fixedly mounted on the lower end of the upper top plate 6.

[0029] A plurality of U-shaped wire inlets are provided on the movable base 5, and the wire inlets and the clamping plate 10 form a clamping cavity.

[0030] like Figure 4 As shown, the electric telescopic rod 8 is started by the power supply 7, so that the electric telescopic rod 8 can drive the upper top plate 6 to move up and down, and the upper top plate 6 moves downward until the clamping plate 10 and the line inlet form a cavity that allows the transmission line to pass through.

[0031] More preferably, a pushing cylinder 2 is fixedly installed inside the supporting base 1 , and a pushing gas rod 3 is connected and installed on the upper part of the pushing cylinder 2 , and the pushing gas rod 3 is connected to the lower end of the movable base 5 .

[0032] A storage groove 4 is provided on the support base 1, and the pushing cylinder 2 is installed in the storage groove 4. When not in use, the pushing cylinder 2 and the pushing gas rod 3 cooperate to make the movable base 5 enter the storage groove 4 provided on the support base 1 when the device is idle, thereby reducing the occupied area of ​​the device. At the same time, the stored movable base 5 can effectively reduce the entry of external dust.

[0033] Embodiment 2 On the basis of the first embodiment, a movable clamping mechanism is provided inside the movable base 5 for cleaning the surface of the power transmission line.

[0034] Specifically, a long strip-shaped groove 501 is opened in the wire inlet of the movable base 5, and a collection box 12 is clamped inside the groove 501; along the axial direction of the groove 501, two symmetrical side grooves 502 are opened on the front and rear sides of the axial direction, and a clamping plate 11 is movably arranged inside each side groove 502; a support block 503 is fixedly installed on the side of each side groove 502.

[0035] Insertion holes are provided on the movable base 5 and on both sides of the groove 501, and the movable racks 18 are inserted into the insertion holes. Correspondingly, two symmetrical rotating mechanisms are installed in the cavity below each wire inlet.

[0036] like Figure 8 As shown, the rotating mechanism includes a connecting rod 15 axially parallel to the groove 501 , a rotating gear 16 and a rotating gear 2 17 , the middle of the connecting rod 15 is connected to the rotating gear 16 , and both ends of the connecting rod 15 are connected to the rotating gear 2 17 ; the moving rack 18 is arranged vertically and meshes with the rotating gear 16 .

[0037] A support plate 13 is arranged above the second rotating gear 17 , and a tooth block 14 meshing with the second rotating gear 17 is prefabricated on the lower surface of the support plate 13 . When the second rotating gear 17 rotates, the support plate 13 can translate.

[0038] like Figure 5 As shown, the support plate 13 is connected to the outer arc surface of the second clamping plate 11, and the support plate 13 translates to drive the second clamping plate 11 to move.

[0039] The lower surface of the first clamping plate 10 and the upper surface of the second clamping plate 11 are both provided with scrapers 20 for cleaning dust on the circuit.

[0040] During use, the cable is clamped into the U-shaped cable inlet opened on the movable base 5, and then the upper top plate 6 moves downward to squeeze the movable rack 18, causing it to move downward and mesh with the rotating gear 16, so that the rotating gear 16 drives the rotating gear 2 17 on both sides to rotate synchronously through the connecting rod 15, so that the rotating gear 2 17 and the tooth block 14 at the lower end of the support plate 13 are meshed, and at the same time, the support plate 13 slidingly installed in the side groove 502 pushes the clamp plate 2 11 to move out of the side groove 502 to clamp the cable, and as the device moves as a whole, the impurities on the surface of the cable are scraped and cleaned, and fall into the collection box 12 inside the lower groove 501, which is convenient for the staff to clean the device as a whole later.

[0041] Preferably, Figure 7 As shown, a limit groove 27 is opened inside the movable base 5, a pressure spring 26 is connected and installed inside the moving rack 18, and a limit block 19 is installed on one side of the moving rack 18. The limit block 19 is connected to the pressure spring 26. The limit block 19 is trapezoidal in side view, and the limit block 19 and the pressure spring 26 form an elastic structure on the moving rack 18.

[0042] In the initial state, the limit block 19 is stuck in the limit groove 27. Since the limit block 19 is trapezoidal, with a larger upper portion and a smaller lower portion, when the upper top plate 6 applies downward pressure, the movable rack 18 can move downward, pushing the limit block 19 into the cavity where the pressure spring 26 is located. When the initial state is restored, the movable rack 18 moves upward, and the limit block 19 plays a limiting role to prevent the movable rack 18 from falling out.

[0043] Embodiment 3 like Figure 3As shown, a plurality of electromagnets 28 are fixedly mounted on the lower surface of the upper top plate 6, the position of the electromagnets 28 corresponds to the position of the moving rack 18, and an electromagnet 23 is fixedly mounted on the upper end of the moving rack 18, and the moving rack 18 is a conductive metal.

[0044] As the upper plate 6 continues to move downward, when it contacts the moving rack 18, the electromagnet 28 inside the upper plate 6 is connected to the electromagnet 1 23 at the upper end of the moving rack 18, and is energized after the power supply 7 receives the signal, generating magnetism, thereby pushing the moving rack 18 to descend, and the splint 2 11 moves outward, and after contacting the cable, the support plate 13 movably connected to the upper end of the splint 11 moves toward the inside of the splint 11.

[0045] Embodiment 4 A connection block is fixed at the connection between the second clamping plate 11 and the support plate 13. A cavity is prefabricated in the connection block. One end of the support plate 13 extends into the cavity and is connected to the slider 24 in the cavity to prevent the support plate 13 from falling off.

[0046] like Figure 5 and Figure 6 As shown, infrared sensors 21 are fixedly installed at the upper and lower ends of the second clamping plate 11, and a pressure sensor 25 is fixedly installed in the cavity.

[0047] When the support plate 13 squeezes the pressure sensor 25, the pressure sensor 25 sends a squeezing signal to the controller, indicating that the cable has been clamped. The controller transmits the signal to the infrared sensor 21 through the transmission line 22, and performs infrared detection on the cable passing through the clamping plate 11. If the temperature rises significantly, it means that there may be a fault point in the cable.

[0048] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
