Description

Technical Field

[0001] This utility model belongs to the field of substation insulator cleaning and spraying, specifically relating to a vector nozzle for cleaning and spraying PRTV insulators in substations. Background Technology

[0002] When cleaning or spraying PRTV (i.e., PRTV anti-flashover coating) on ​​the insulating terminals of a substation, a drone can be used to carry the spraying equipment to a predetermined area and altitude to clean or spray the insulating terminals. During the spraying process, the cleaning fluid and other substances need to be sprayed through the nozzle. However, the nozzle adjustment method in the existing technology is controlled by the movement of the drone, which leads to a reduction in the spraying accuracy. Therefore, the existing technology needs to be improved.

[0003] The currently searched Chinese patent, "UAV Spraying Mechanism and Spraying UAV" (publication number CN214682467U), includes a Y-shaped support assembly, a spraying assembly, and a material conveying assembly. The Y-shaped support assembly is detachably mounted on the lower end of the UAV, the spraying assembly is detachably mounted through the center of the Y-shaped support assembly, and the material conveying assembly is mounted on the ground and connected to the spraying assembly through a material conveying pipe. The entire mechanism of this patent can be disassembled and stored separately, facilitating transportation and storage. At the same time, the Y-shaped support assembly can effectively support the spraying assembly, preventing the spraying assembly from moving relative to the UAV during the spraying process, ensuring uniform coating and spraying quality. However, this patent cannot solve the problem of low spraying precision of existing nozzles. Summary of the Invention

[0004] The purpose of this invention is to provide a vector nozzle for cleaning and spraying PRTV on substation insulators, in order to solve the problem of low spraying accuracy of existing nozzles.

[0013] Preferably, the axis of the through hole is perpendicular to the axis of the nozzle tube.

[0014] Preferably, both the adjustment disc and the nozzle tube are made of insulating material.

[0015] The working principle of this utility model is as follows: In use, the UAV carries the nozzle frame and its components to the predetermined area via its boom. Then, the vertical servo is activated. The output shaft of the vertical servo is fixedly connected to the adjustment plate, which can drive the adjustment seat to deflect vertically. During the deflection process, the adjustment seat can adjust the vertical direction of the spray tube inside the nozzle tube. Then, the horizontal servo is activated.

[0026] The following detailed description illustrates the specific implementation method:

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides a vector nozzle for cleaning and spraying PRTV on substation insulators, including a nozzle frame 1. A fixing frame 2 is fixedly connected to the back of the nozzle frame 1, and an adjusting plate 3 is fixedly connected to the front of the nozzle frame 1 (the fixing frame 2 and the adjusting plate 3 are parallel and spaced plates). An adjusting seat 4 is installed inside the fixing frame 2 through a bearing. Specifically, the adjusting seat 4 is installed between the fixing frame 2 and the adjusting plate 3. A protruding post 41 is provided on one side of the adjusting seat 4, and the protruding post 41 is inserted into the inner ring of the bearing of the fixing frame 2.

[0028] The vertical servo 5 is installed inside the adjustment seat 4. Specifically, the adjustment seat 4 has a first groove for installing the vertical servo 5. The side of the vertical servo 5 has a protrusion 11, which is locked to the adjustment seat 4 by screws. The output shaft of the vertical servo 5 is fixedly connected to the adjustment plate 3. When the output shaft of the vertical servo 5 rotates, it drives the adjustment seat 4 to swing in the vertical direction relative to the adjustment plate 3 and the fixed frame 2.

[0029] The adjustment seat 4 is equipped with a horizontal servo 6. Specifically, the adjustment seat 4 is provided with a second channel for installing the horizontal servo 6. The side of the horizontal servo 6 is provided with a protrusion 11. The second channel is formed by the space between two lugs 12 on the side of the adjustment seat 4. The protrusion 11 of the horizontal servo 6 is locked to the lugs 12 by screws.

[0030] An adjustment disc 7 is fixedly connected to the outside of the output shaft of the horizontal servo motor 6. The lower end of the adjustment disc 7 is connected to the nozzle pipe 8. When the output shaft of the horizontal servo motor 6 rotates, it drives the nozzle pipe 8 and the spray pipe 10 installed inside the nozzle pipe 8 to swing in the horizontal direction.

[0031] The above-mentioned nozzle frame 1 is made of insulating material (insulating material can reduce the impact of high voltage on the equipment). Two symmetrically distributed boom rods 9 are fixedly connected to the nozzle frame 1 (the boom rods 9 can be connected to the drone, and the two boom rods 9 can make the installation of the nozzle frame 1 more stable). The boom rods 9 are hollow structures (the hollow structure can effectively reduce the weight of the equipment, and can also be used as a passage for the spray pipe 10). The spray pipe 10 (the spray pipe 10 is a flexible hose that can undergo elastic deformation) is connected inside the boom rod 9. The spray pipe 10 passes through and extends out of the nozzle tube 8.

[0032] The aforementioned adjusting disc 7 and nozzle tube 8 are an integral structure (an integral structure can enhance the overall strength of the adjusting disc 7 and nozzle tube 8). The center of the adjusting disc 7 has a through hole 71, through which the output shaft of the horizontal servo motor 6 passes and is fixed. The axis of the through hole 71 is perpendicular to the axis of the nozzle tube. Both the adjusting disc and the nozzle tube are made of insulating material.

[0033] The working principle of this utility model is as follows: In use, the UAV carries the nozzle frame and its components to the predetermined area via its boom. Then, the vertical servo is activated. The output shaft of the vertical servo is fixedly connected to the adjustment plate, which can drive the adjustment seat to deflect vertically. During the deflection process, the adjustment seat can adjust the vertical direction of the spray tube inside the nozzle tube. Then, the horizontal servo is activated. The horizontal servo can drive the nozzle tube and the spray tube to adjust horizontally via its output shaft and the adjustment plate fixedly connected to the output shaft. This can effectively improve the spraying accuracy, and the nozzle has a compact structure and small size.

[0034] The beneficial effects of this utility model are as follows: By adding an adjustment seat, adjustment plate and servo motor to the nozzle frame, the vertical angle of the nozzle tube can be adjusted by the vertical servo motor and the horizontal angle of the nozzle tube can be adjusted by the horizontal servo motor during use. This eliminates the need for the drone to adjust the direction of the nozzle tube, making the spraying more precise.
