[0002] Insulators, as a special type of insulating control, play a crucial role in overhead transmission lines. Their applications are constantly expanding. In the past, they were primarily used on utility poles; now, many suspended disc-shaped insulators made of materials such as glass or ceramics can often be seen at one end of high-voltage power line towers.

[0003] Insulators must withstand various electromechanical stresses caused by changes in environmental and electrical load conditions. If they fail as a result, they lose their vital function, thereby impairing the performance and service life of the entire line. Therefore, cleaning insulators is a necessary maintenance measure to ensure the normal use and operation of the line.

[0004] Currently, the cleaning and maintenance of insulators in railway power supply cantilever arms mainly relies on manual wiping or high-pressure water jet washing. This method not only increases the workload but also poses a safety hazard as residual water can easily cause freezing accidents in winter. Utility Model Content

[0034] See Figures 1-4 An embodiment of this application provides an insulator cleaning device, which includes a base assembly, a telescopic rod 30, and a cleaning head. The base assembly includes a base 11 and a chassis 12 rotatably mounted on the base 11; one end of the telescopic rod 30 is fixedly connected to the chassis 12; the cleaning head is located at the end of the telescopic rod 30 away from the chassis 12, and the cleaning head includes a cleaning section 50 and a heating section 60. The cleaning section 50 has heating sections 60 at both ends, and the two heating sections 60 are arranged opposite to each other so that the cleaning section 50 and the two heating sections 60 form a semi-enclosed cavity structure. The cavity structure is used for the insulator to enter. The cleaning section 50 has a water spray nozzle 51 for spraying water onto the insulator, and the heating section 60 is used to heat the cleaned insulator.

[0035] In this embodiment, the water nozzle 51 of the cleaning unit 50 can spray water onto the insulator to rinse its surface. Simultaneously, the heating unit 60 heats the insulator after cleaning, not only removing moisture but also drying any remaining fine impurities to a certain extent, further ensuring the insulator's cleanliness and preventing residual water from causing freezing accidents in winter. The base assembly includes a rotatable chassis 12 and an adjustable telescopic rod 30, allowing the cleaning head to be flexibly adjusted in position and angle to adapt to insulators of different locations and specifications. Regardless of the insulator's installation angle or height, rotating the chassis 12 and adjusting the telescopic rod 30 ensures the cleaning head's cavity structure accurately fits into the insulator, guaranteeing smooth cleaning and heating operations. Furthermore, after cleaning one angle, the chassis 12 can rotate the cleaning head to clean the other side of the insulator, achieving comprehensive cleaning.

[0036] In some embodiments, the cleaning section 50 is provided with at least one row of water nozzles 51 along a first direction, and an air nozzle 52 is provided between two adjacent water nozzles 51.

[0037] In this embodiment, an air nozzle 52 is provided between two adjacent water nozzles 51. This allows the air nozzle 52 to work closely with the water nozzle 51, forming a collaborative working mode. During the cleaning process, after the water nozzle 51 completes its water spraying, the adjacent air nozzle 52 immediately activates, spraying out a high-speed airflow. This airflow can quickly blow away residual water stains and impurities on the surface of the insulator, preventing water stains from remaining on the insulator surface and reducing various problems that may be caused by water stains, such as the risk of freezing in winter. At the same time, the presence of the air nozzle 52 can also enhance the cleaning force to a certain extent. Through the impact of the airflow, it assists the water nozzle 51 in more thoroughly removing stubborn stains, further improving the cleanliness of the insulator cleaning.

[0038] For example, a row of water nozzles 51 is arranged on the cleaning section 50 along a first direction. There are multiple water nozzles 51 in the row of water nozzles 51, and an air nozzle 52 is arranged between any two adjacent water nozzles 51.

[0039] For example, the cleaning section 50 is provided with multiple rows of water nozzles 51 along the first direction. Each row of water nozzles 51 contains multiple water nozzles 51, and an air nozzle 52 is provided between any two adjacent water nozzles 51.

[0040] In some embodiments, at least one row of water nozzles 51 includes a first angle nozzle, a straight nozzle, and a second angle nozzle arranged sequentially along a first direction, wherein the spray direction of the first angle nozzle and the spray direction of the second angle nozzle are respectively inclined toward the spray direction of the straight nozzle.

[0041] In this embodiment, the first-angle nozzle, the direct nozzle, and the second-angle nozzle included in at least one row of water nozzles 51, due to their different spray directions, can rinse the insulator entering the cavity structure from multiple dimensions. The direct nozzle can directly and precisely spray water onto the front area of ​​the insulator, while the first-angle nozzle and the second-angle nozzle are tilted towards the spray direction of the direct nozzle, which can cover the sides of the insulator and corners, recesses, and other areas that are difficult to reach by the direct nozzle. This multi-directional spray design effectively expands the cleaning range, avoids the cleaning blind spots that may exist in traditional single-directional nozzles, ensures that all areas of the insulator surface are thoroughly cleaned, and significantly improves the comprehensiveness and cleanliness of the cleaning.

[0042] In some embodiments, the heating part 60 is an arc-shaped heating plate, the centers of the two arc-shaped heating plates coincide, and the centers of the two arc-shaped heating plates coincide with the axis of the chassis 12.

[0043] In this embodiment, after the cleaning unit 50 completes cleaning one side of the insulator, the chassis 12 rotates, driving the cleaning head to rotate via the telescopic rod 30. This allows the cleaning head to heat the other side of the insulator. At this time, the centers of the two arc-shaped heating plates coincide with the axis of the chassis 12, ensuring that the cleaning head always rotates around the insulator. This ensures that the cleaning direction, heating direction, and range are not affected during the adjustment of the device's working position. Furthermore, the heating unit 60 uses arc-shaped heating plates, and the centers of the two arc-shaped heating plates coincide, allowing the heating area to better fit the arc-shaped surface of the insulator. When the insulator enters the semi-enclosed cavity structure of the cleaning head, the two arc-shaped heating plates can form a uniform heating coverage of the insulator from opposite sides, avoiding the localized insufficient heating or overheating that may occur with flat heating plates. Simultaneously, the arc design of the heating plates allows heat to be more concentrated on the insulator surface, accelerating moisture evaporation and ensuring that the cleaned insulator dries quickly and thoroughly, further reducing safety hazards such as freezing in winter.

[0044] In some embodiments, reflectors 63 are respectively provided on the surfaces of the two heating parts 60 that are close to each other.

[0045] In this embodiment, after a reflector plate 63 is provided on the surfaces of the two heating parts 60 that are close to each other, the reflector plate 63 can reflect the heat emitted by the heating parts 60 back into the cavity structure where the insulator is located, reducing the loss of heat to the external environment. The heat that might have diffused to the outside of the heating parts 60 is intercepted by the reflector plate 63 and guided to the insulator, so that more heat is concentrated on the cleaned surface of the insulator, which significantly improves the energy utilization efficiency, reduces the energy loss during the heating process, and is more in line with energy-saving requirements.

[0046] Specifically, the heating part 60 is provided with a heating wire 61.

[0047] In some embodiments, the base assembly includes a motor and a gear 13. The outer periphery of the chassis 12 is evenly distributed with teeth, and the chassis 12 meshes with the gear 13 through the teeth. The motor is used to drive the gear 13 to rotate.

[0048] In this embodiment, the motor is mounted on the base 11 and drives the gear 13 to rotate. The rotation of the gear 13 drives the chassis 12 to rotate, which in turn drives the cleaning head to rotate via the telescopic rod 30. Simultaneously, due to the extremely high precision of the meshing transmission between the gear 13 and the chassis 12, the motor's speed and rotation angle can be precisely transmitted to the chassis 12 through the gear set 13. When it is necessary to rotate the cleaning head to heat the other side of the insulator, this precise transmission allows for precise control of the chassis 12's rotation angle, ensuring that the rotation amplitude of the cleaning head is just right, guaranteeing that the water nozzle 51 of the cleaning section 50 and the arc-shaped heating plate of the heating section 60 are always aligned with the area of ​​the insulator to be treated.

[0049] In some embodiments, the cleaning head includes a mounting base 40, a cleaning section 50 located on the mounting base 40, and heating sections 60 located on both sides of the cleaning section 50 along a second direction; the mounting base 40 is provided with a sliding groove 72 along the second direction, and each heating section 60 is slidably connected to the corresponding sliding groove 72, and the second direction is perpendicular to the first direction.

[0050] In this embodiment, the mounting base 40 of the cleaning head is provided with a sliding groove 72 along the second direction. The heating parts 60 are slidably connected to the corresponding sliding grooves 72, and the second direction is perpendicular to the first direction. This design allows the heating parts 60 to slide flexibly along the sliding grooves 72 in the second direction, thereby adjusting the distance between the two heating parts 60. When dealing with insulators of different diameters and specifications, the size of the semi-enclosed cavity structure can be changed by sliding the heating parts 60 to ensure that the cavity can fit the insulator, allowing the heating parts 60 to fit tightly against the surface of the insulator, ensuring the uniformity and sufficiency of the heating effect, and greatly improving the device's adaptability to diverse insulators.

[0051] Furthermore, the heating unit 60 is slidably connected to the slide groove 72 via the slider 71; the cleaning head includes a screw 73, which is rotatably mounted on the mounting base 40, the slider 71 is threadedly connected to the mounting base 40, and the knob 74 is located at the end of the screw 73 that extends out of the mounting base 40.

[0052] In this embodiment, a limiting structure is provided on the mounting base 40. The limiting structure is used to limit the movement of the screw 73 in the second direction, so that when the knob 74 is rotated, the screw 73 rotates in place, thereby allowing the slider 71 located on the mounting base 40 to move in the second direction.

[0053] In other embodiments, the slider 71 is directly mounted on the linear motion mechanism via an electric push rod or directly on the linear motion mechanism, so that the heating unit 60 can be electrically controlled, allowing the operator to remotely control the movement of the heating unit 60 from the ground.

[0054] In some embodiments, a water tank 14 is provided on the chassis 12, and the water tank 14 is connected to the water nozzle 51 through a water pipe; an air pump 15 is provided at the end of the telescopic rod 30 away from the chassis 12, and the air pump 15 is connected to the air nozzle 52 through an air pipe.

[0055] In this embodiment, the water tank 14 is directly connected to the water nozzle 51 through a water pipe, and the air pump 15 is directly connected to the air nozzle 52 through an air pipe, forming a complete cleaning power supply system.

[0056] Specifically, for ease of use, the water tank 14 is connected to the water nozzle 51 via a hose, and a booster pump can be added for use. A water inlet is provided on one side of the water tank 14 for adding water.

[0057] In some embodiments, a camera is installed on the cleaning head, and the camera is connected to a remote display device.

[0058] In this embodiment, the camera mounted on the cleaning head can capture the status of the insulator and the relative position of the cleaning head and the insulator in real time, and transmit the image to a remote display device. By viewing the display, the operator can clearly see whether the water nozzle 51 of the cleaning section 50 is accurately aimed at the insulator, whether the heating section 60 completely surrounds the insulator, etc., thereby precisely controlling the extension and retraction of the telescopic rod 30, the rotation of the chassis 12, and the sliding of the heating section 60, ensuring that the cleaning and heating operations are precisely applied to all parts of the insulator. Especially for some blind spots or hidden insulators, the camera can provide intuitive visual support, avoiding cleaning omissions due to unclear observation and ensuring the comprehensiveness of the cleaning.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
