Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] In this embodiment, the spraying tool is used to fix and control the spraying state of the spray bottle 70. The spraying tool includes: a rod, a retainer 20, a slider 30, and a drive component. The retainer 20 is disposed at the first end of the rod and is used to fix the spray bottle 70. The slider 30 is movably disposed on the first end of the rod, and the slider 30 is spaced apart from the retainer 20. The slider 30 moves to have a spraying position that abuts against the nozzle of the spray bottle 70 and a clearance position that separates from the nozzle of the spray bottle 70. The drive component is disposed at the first end of the rod and is capable of driving the slider 30 to move.

[0030] In this way, the operator can hold the second end of the pole, allowing the first end of the pole to approach the high-level substation equipment. The fixing device 20 secures the spray bottle 70 to the first end of the pole. The operator controls the drive mechanism to move the slider 30, switching it from a clearance position to a spraying position. This allows the slider 30 to press the nozzle of the spray bottle 70, spraying out the lubricating and rust-removing fluid for maintenance of the high-level substation equipment. This method avoids the need for operators to climb to heights and eliminates the need to shut down the substation equipment, making the operation simple and quick. Therefore, the technical solution of this application effectively solves the problem of complex operation in related technologies for maintaining high-level substation equipment.

[0031] In this embodiment, the slider 30 presses the nozzle of the spray bottle 70, causing the spray bottle 70 to spray out liquid. The liquid seeps into the rusted parts or rusted shaft, serving as a lubricant and rust remover.

[0032] like Figure 1As shown, the spraying tool also includes a slide rail mounted on the first end of the rod. The slider 30 is movably mounted on the slide rail and engages with the guide rail. The slide rail design makes the movement of the slider 30 smoother, reduces the shaking of the slider 30 during movement, and improves the spraying accuracy, making it suitable for scenarios requiring precise control of the spraying range.

[0033] like Figure 1 As shown, the driving component includes a power supply 41, a drive motor 42, and a control unit. The power supply 41 is electrically connected to the drive motor 42, the control unit is controlled by the power supply 41, and the slider 30 is driven by the motor shaft of the drive motor 42. The control unit controls the polarity of the power supply 41 to cause the motor shaft of the drive motor 42 to rotate forward or backward, allowing the slider 30 to switch between a spraying position and an avoidance position. Thus, the operator can control the polarity of the power supply 41 by controlling the control unit, thereby controlling the rotation direction of the motor shaft and the movement direction of the slider 30. This facilitates the operator's control of the spraying and stopping of the spray bottle 70 from the ground. This design allows the operator to easily control the spraying and stopping of the spray bottle 70 through the control unit, simplifying operation and reducing labor intensity.

[0034] In this embodiment, the drive motor 42 is a DC motor, and the controller can control the polarity of the DC motor, thereby enabling the motor shaft to rotate forward or backward. The controller is operated wirelessly via remote control, a non-contact design that enhances safety and reliability. The power supply 41 is a 12V, 5000MA power supply capable of both forward and reverse output. The power supply 41 is rechargeable and stable. The power supply 41 has a built-in power level display component. The power level indicator light is used to alert the operator to the power level of the power supply 41. If the power level is below 30%, the indicator light is red; if the power level is between 30% and 70%, it is yellow; and if the power level is approximately 70% to 100%, it is green. The drive motor 42 has an output torque of 30N and operates with a stroke between 0mm and 30mm to ensure uniform compression of the nozzle.

[0035] In this embodiment, the control unit and the power supply 41 can be assembled together and installed at the top of the rod.

[0036] like Figure 1 As shown, the motor shaft has a first external thread section, and the slider 30 has a first internal thread section. The first external thread section and the first internal thread section are threadedly engaged. This threaded engagement makes the movement of the slider 30 more stable, avoiding the shaking of the slider 30 caused by the rotation of the motor shaft, and improving the uniformity and consistency of the spraying. The structure of the first external thread section and the first internal thread section is simple and easy to manufacture.

[0037] like Figure 1As shown, the spraying tool also includes a limiting cover 50 disposed on the second end of the pole body, the limiting cover 50 being a preset safe distance from the end face of the first end of the pole body. The limiting cover 50 prevents the operator's hands from getting excessively close to the first end of the pole body during use, limiting the distance between the operator's grip and the high-level substation electrical equipment, thus maintaining a safe distance between the operator and the substation electrical equipment and improving the operator's safety when using the spraying tool.

[0038] In this embodiment, the preset safety distance between the limiting cover 50 and the end face of the first end of the rod is in the range of 1.5 meters to 5 meters.

[0039] like Figure 1 As shown, the spraying tool also includes a shield 60 mounted on the shaft, located between the limiting shield 50 and the retainer 20. The shield 60 further protects the operator from liquid splashing during spraying. Furthermore, in the event of liquid leakage from the spray bottle 70, the shield 60 prevents liquid from flowing down the shaft to the operator's grip area.

[0040] In this embodiment, the shield 60 adopts a high-strength insulating latex double-layer design, so that if liquid leakage occurs from the nozzle, the liquid will not easily flow down the rod.

[0041] like Figure 1 As shown, the pole body comprises multiple pole segments 11, with adjacent pole segments 11 being detachably connected to allow for adjustment of the total length of the pole body. This design enables the spraying tool to adjust its length according to different usage scenarios, improving its adaptability and flexibility, and making it suitable for spraying operations from the ground up. It also allows operators to select the appropriate number of pole segments 11 based on the height of the substation equipment to be maintained, ensuring that the total length of the pole body is compatible with the height of the substation equipment, facilitating the use of the spraying tool.

[0042] In this embodiment, the rod is an insulating rod with a frosted layer on its outer surface, giving it high strength. Operators can grip it comfortably, and the insulating rod material is suitable for different voltage insulation requirements, providing excellent insulation safety performance.

[0043] In this embodiment, the operator can adjust the total length of the pole according to the effective length of the 10-500kV voltage level to ensure that the effective distance of the pole is always kept within a safe distance.

[0044] like Figure 1As shown, the rod body also includes a connecting ring 12 connecting two adjacent rod segments 11, with a second internal thread section on the connecting ring 12. One end of one of the two adjacent rod segments 11 has a second external thread section, and the other end of the other two adjacent rod segments 11 has a third external thread section. The second internal thread section and the second external thread section are threadedly engaged, and the second internal thread section and the third external thread section are also threadedly engaged, to securely connect the two adjacent rod segments 11. This connection method makes the connection between the two adjacent rod ends more robust, improving the stability and reliability of the spraying tool. The connecting ring 12 and the rod segments 11 have a simple structure and are easy to manufacture.

[0045] like Figure 1 As shown, the retainer 20 includes a binding rope and a ratchet tensioner disposed at the first end of the binding rope. The ratchet tensioner has a tightened state, fixed to the second end of the binding rope, and a loosened state, separated from the second end of the binding rope. When the ratchet tensioner is in the tightened state, the spray bottle 70 is fixed within the binding rope. This design makes the fixing of the spray bottle 70 more flexible, allowing the tightness of the binding rope to be adjusted according to the size and shape of the spray bottle 70, so that the spraying tool can be adapted to spray bottles 70 of different diameters, improving the adaptability of the spraying tool. At the same time, the ratchet tensioner also makes the fixing of the spray bottle 70 more secure, reducing the shaking or falling off of the spray bottle 70 during use, and improving the stability and safety of spraying.

[0046] In this embodiment, the ratchet tensioner is the anti-loosening ratchet tensioner described in Chinese invention patent application publication number CN 116512176A.

[0047] This application also provides a spraying apparatus, including a spraying tool and a spray bottle 70 disposed on the spraying tool, wherein the spraying tool is the aforementioned spraying tool. Since the aforementioned spraying tool can solve the problem of complex operation in maintaining live equipment in high-altitude substations in related technologies, the spraying apparatus having this spraying tool can solve the same technical problem.

[0048] The inventors discovered that substation outdoor live-line equipment has numerous metal components made of materials such as copper, carbon steel, galvanized steel, stainless steel, and aluminum alloys, and corrosion of these metals is a common phenomenon. Corrosion of metal components reduces equipment reliability and creates safety hazards. Practice has shown that many substation live-line equipment failures are related to corrosion of metal components. Therefore, the safety hazards posed by corrosion to substation live-line equipment are increasing, and the ability to effectively, promptly, and conveniently address equipment corrosion has become an urgent problem to be solved. Currently, rust removal operations can only be carried out in an environment where all equipment is powered off, which faces problems such as reduced power supply, a weak power grid structure, and increased risks to personnel. For live-line equipment installed at a height of more than 2.5 meters, if lubrication and rust removal are required, power must be shut off, increasing the operation and maintenance costs for power grid companies. Rust removal operations after a power outage require operators to climb to a height and use rust removers and lubricants, a process fraught with the risks of working at height and falls. When lubricating live equipment, grease must be added to the rotating parts. Grease cannot lubricate the gaps between shafts and will not provide lubrication. When using bottled lubricating oil, the oil can may not be secured and could easily fall, posing a risk to the power grid, especially when the equipment is energized. Furthermore, bottled lubricating oil is prone to leakage, leading to low work efficiency.

[0049] Applying the technical solution in this embodiment, the lubricating and rust-removing liquid in spray bottle 70 can lubricate and remove rust from metal components. Furthermore, using a spraying tool avoids the need for operators to climb to heights, improving the efficiency of lubrication and rust removal for substation equipment, enhancing the health of the equipment, ensuring its safe and reliable operation, and reducing the need for operators to climb high-altitude areas of substation equipment, thus ensuring operator safety and eliminating potential safety hazards.
