[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] Example 1:

[0028] Pole-mounted circuit breakers, lightning arresters, pole-mounted transformers, drop-out fuses, and other equipment are susceptible to short circuits and grounding faults caused by foreign objects catching on them during bird nesting season or during thunderstorms and strong winds, due to partially exposed parts or cracks or damage to the insulation sheaths. For example, bare jumper wires or damaged insulation can easily cause short circuits and grounding faults in inclement weather. Exposed wire clamps or cracks or damage to the insulation sheaths can also easily cause short circuits and grounding faults in inclement weather.

[0029] Currently, the traditional insulation treatment for equipment mounted on distribution line poles, such as 10kV distribution line poles, primarily involves manual insulation wrapping or application of insulating materials after a power outage. This not only consumes considerable time and manpower, but also results in prolonged power outages, causing significant inconvenience to users and significant economic losses. Operators operating in live environments face significant safety risks. Furthermore, the spraying tools used for insulation treatment of distribution line poles utilize nozzles and other components to apply paint to the equipment. To ensure a sufficient coating surface, excess paint is sprayed onto the sides of the pole or on top of the equipment, resulting in paint waste and environmental pollution.

[0030] In order to solve at least one of the above problems, Figure 1 As shown, this embodiment provides a distribution line pole mounted equipment spraying tool, including an operating rod 1, a spray head 2, a pipe 3, a paint supply component 4 and a paint recovery component 5, etc.

[0031] The operating lever 1 is the operating part of the operator; when working, the operator holds the operating lever 1 and moves the spray head 2 to the equipment position on the distribution line pole that needs to be sprayed.

[0032] In some embodiments, when working in an unpowered or power outage environment, the operating rod 1 can be a non-insulated rod, allowing for flexible material selection. In other embodiments, the operating rod 1 is an insulated rod; workers holding the insulated rod while spraying equipment on distribution line poles can meet the requirements of live work and avoid losses caused by power outages.

[0033] The position of the nozzle 2 on the operating rod 1 can be set according to actual needs; in one embodiment, the nozzle 2 is at the end of the operating rod 1, which is easy to operate and avoids interference of the excess length of the operating rod 1 on spraying.

[0034] Optionally, the spray head 2 is connected to a paint supply assembly 4 via a pipe 3. When in operation, the paint supply assembly 4 delivers paint to the spray head 2 via the pipe 3.

[0035] In some embodiments, a portion of the pipe 3 can be fixed to the operating rod 1 by binding or the like, so as to avoid the pipe 3 swinging during spraying and improve the spraying stability.

[0036] like Figure 2 As shown, the paint supply assembly 4 includes a storage tank 401 for filling paint, and a supply pump 402; the inlet end of the supply pump 402 is connected to the storage tank 401, and the outlet end is connected to the pipeline 3. During operation, the supply pump 402 can pump the paint in the storage tank 401 into the pipeline 3, and the paint is then delivered to the printhead 2 through the pipeline 3. The paint supply assembly 4 can be an air compressor.

[0037] like Figure 3 As shown, the paint recovery assembly 5 includes a connecting beam 501, a baffle 502, a guide groove 503 and / or a container 504, etc.

[0038] One end of the connecting beam 501 is connected to the operating rod 1, and the other end is provided with a baffle 502. The function of the connecting beam 501 is to extend the baffle 502 to the side of the distribution line column and the equipment on the distribution line column away from the spray head 2 during spraying. Optionally, the connecting beam 501 has an arc-shaped structure to meet the transition between the distribution line column and the equipment on the distribution line column, so that the paint spray direction of the spray head 2 is toward the baffle 502, so that the baffle 502 can collect the paint. Alternatively, the connecting beam 501 has other openings, such as a rectangular structure with one end open, or an irregular structure, which can meet the transition between the distribution line column and the equipment on the distribution line column. The width of the baffle 502 can be greater than the outer diameter of the distribution line column and the size of the equipment on the distribution line column to ensure the collection of excess paint.

[0039] The baffle 502 is provided with a container 504 for recovering the paint blocked by the baffle 502. The container 504 is provided at one end of the baffle 502, and the paint blocked by the baffle 502 flows into the container 504 along the baffle 502 under its own gravity.

[0040] The container 504 can be a collection can, bottle, or other container. In some embodiments, to improve collection efficiency, a guide groove 503 can be provided on the connecting beam 501, with the inlet of the container 504 connected to the guide groove 503. During operation, the paint blocked by the baffle 502 flows along the baffle 502 under its own gravity into the guide groove 503, and then flows along the guide groove 503 into the inlet of the container 504.

[0041] One of the working processes of the tool in this embodiment is:

[0042] Hold the operating lever 1 and use the spray nozzle 2 to fully spray the exposed points of equipment such as pole-mounted circuit breakers, guide wires, wire clamps, and disconnectors. No exposed points or gaps should be left. After curing, the thickness of the sprayed insulation layer should be no less than 0.6mm. Drop-out fuses and disconnectors should be in the closed state during spraying to prevent poor conductivity at metal contact points caused by spraying. After construction is completed, conduct a key acceptance inspection of the spray appearance and electrical performance of the equipment through visual inspection, telescopes, drones, and / or contact testers. Check whether the coating surface is smooth and whether there are defects such as uneven spraying and missed spraying areas.

[0043] Before insulation spraying, the equipment should be cleaned with a cleaning agent under voltage, and insulation spraying can be carried out 5 minutes after the cleaning is completed.

[0044] Work must be carried out in good weather. It is strictly prohibited to carry out work in the event of thunderstorms, rain, snow, fog, wind speeds exceeding level 5, or relative humidity exceeding 80%. Other influencing factors near the construction area should be investigated. If there are vehicles, greenhouses, crops, etc., protective shielding should be provided to prevent paint spillage and property disputes.

[0045] Before commencing operations, observe the surrounding environment and pay attention to safety. Before climbing the pole, operators should plan the cleaning sequence of their equipment in advance to avoid duplication of work. Operators should select appropriate cleaning locations and angles, using existing cleaning equipment equipped with a nozzle. The operation process must meet safety control requirements and cleaning quality standards. Protective equipment and protective shields must be worn to minimize spillage of cleaning agents and avoid damage or contamination to personnel, property, and the environment.

[0046] When cleaning, it is usually done from top to bottom. Clean the cleaning points at three angles: with the gun tip facing downward, clean the upper end surfaces of all cleaning points; with the gun tip horizontal, clean the outer sides of all cleaning points; with the gun tip facing upward, clean the lower end surfaces of all cleaning points. Avoid unnecessary pauses or jumps in the cleaning sequence to ensure that each cleaning point is cleaned evenly. The operator's observation angle is incomplete due to the obstruction of the equipment. At the same time, the ground observer uses a telescope to observe the cleaning effect and promptly remind the cleaning personnel of the cleaning status to avoid missing cleaning equipment. After cleaning is completed, wait at least 5 minutes before proceeding with the following spraying operations.

[0047] Plan the spraying locations and sequence in advance. If the original protective covering of the equipment is severely damaged, it should be removed before spraying. Operators should select appropriate spraying locations and angles before spraying. Protective equipment should be worn and shielding measures should be implemented to minimize paint spillage and avoid damage or pollution to personnel, property, and the environment.

[0048] When spraying, the process is typically from top to bottom. The spray points are sprayed at three angles: With the nozzle pointing downward, spray the upper surfaces of all spray points; with the nozzle horizontal, spray the outer surfaces of all spray points; and with the nozzle pointing upward, spray the lower surfaces of all spray points. Avoid unnecessary pauses or jumps in the spray sequence to ensure even coverage of each spray point. Similarly, operators' viewing angles are limited by equipment obstruction. Ground observers use telescopes to observe the spraying results and promptly alert the sprayers to spray status, avoiding defects such as missed sprays and uneven spraying.

[0049] Optional live cleaning standards include comprehensive cleaning of exposed points such as pole-mounted circuit breakers, guide wires, wire clamps, and lightning arresters. After cleaning, the equipment should have a smooth, bright surface, free of residual stains and dirt (excluding difficult-to-remove contaminants such as chemicals and cement), and no dripping of wastewater.

[0050] The standard for optional insulation spray coating is to fully spray exposed points on pole-mounted circuit breakers, guide wires, wire clamps, lightning arresters, and other components, leaving no exposed spots or gaps. After curing, the sprayed insulation layer must be at least 0.6mm thick. Drop-out fuses and disconnectors must be closed during spray coating to prevent poor conductivity at metal-to-metal contact points. For sheathed equipment, if the existing sheath is severely damaged, remove it before spraying. If the existing sheath is intact, spray the entire sheath and a 10-20cm area around the external leads.

[0051] The spraying points of the guide wires and equipment connection points are all the exposed points of the guide wires and equipment wire clamps; the spraying standard is to spray all the exposed points of the entire guide wire and equipment wire clamps.

[0052] For dropout fuses, spray the exposed metal sections at both ends of the fuse rod. The spraying standard is for the incoming and outgoing wiring connections, extending 10-20 cm from the incoming and outgoing wiring terminals to prevent the risk of discharge from the crossarm. Spraying should be performed when the dropout fuse is closed; do not spray when it is disconnected. For dropout switches installed near tree barriers, bird nests, or locations with potential tripping hazards, spray the mounting crossarm as needed.

[0053] The spraying locations for disconnectors are the blade arms and the exposed metal parts at both ends. The spraying standard is to target the incoming and outgoing wiring connections of the disconnector. Starting from the incoming and outgoing wiring terminals, spray 10-20 cm outward to prevent the risk of discharge from close proximity to the crossarm. Spraying should be performed when the disconnector is closed; do not spray when it is disconnected.

[0054] The spraying points of the pole-mounted circuit breaker are the exposed metal parts at both ends of the circuit breaker's input and output lines; the spraying standard is for the circuit breaker's input and output line connection parts, that is, starting from the input and output line terminal and extending outward to spray 10cm~20cm.

[0055] The spraying points of the transformer are the exposed points of the wiring terminals on the high and low voltage sides; the spraying standard is to extend the spray outward from the wiring terminals for 10cm to 20cm.

[0056] The spraying point of the lightning arrester is the exposed point of the terminal. The spraying standard is to extend the spray outward from the terminal for 10cm to 20cm.

[0057] After the construction is completed, the two acceptance items of spray coating appearance and electrical performance shall be inspected. If there are any defects, rectification shall be organized. The optional acceptance standards and methods are shown in Table 1:

[0059]

[0060] Example 2:

[0061] like Figure 4 As shown, this embodiment provides a distribution line pole equipment spraying tool. Unlike Example 1, the operating rod 1 is provided with a first adjustment part 101 and a second adjustment part 102 with opposite adjustment directions at one end close to the nozzle 2; and the paint recovery component 5 also includes a first disassembly part 505 and a second disassembly part 506.

[0062] Optionally, the first adjustment portion 101 and the second adjustment portion 102 are used to adjust the angle of the nozzle 2 in two mutually perpendicular directions to adapt to spraying at different positions or angles, thereby improving flexibility. The first adjustment portion 101 and the second adjustment portion 102 can be implemented by bolt holes and bolts, and adjustment and locking are achieved by loosening and tightening the bolts, which will not be described in detail here.

[0063] Optionally, a first detachment portion 505 is provided between the connecting beam 501 and the operating rod 1 for detaching the entire paint recovery assembly 5 from the operating rod 1; a second detachment portion 506 is provided between the connecting beam 501 and the baffle 502 for detaching the baffle 502 from the connecting beam 501. It is understood that in some scenarios, during spraying, interference between conductive or other equipment and the paint recovery assembly 5, or the baffle 502 therein, may prevent the spray head 2 from reaching the spraying position. In this case, the first detachment portion 505 or the second detachment portion 506 may be required to detach the paint recovery assembly 5 or the baffle 502, allowing the spray head 2 to reach the spraying position, thereby increasing the flexibility of tool use. Alternatively, in some cases, if the baffle 502 needs to be replaced for maintenance or size adjustment, the baffle 502 can be detached using the second detachment portion 506. The first detachment portion 505 and the second detachment portion 506 may be implemented with bolts or other fasteners, which will not be described in detail here.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
