Description

Technical Field

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

[0002] In power systems, substation insulators are critical components ensuring the safe and stable operation of transmission lines. However, due to prolonged exposure to harsh environments (such as high temperatures, humidity, and strong winds), insulators are prone to deterioration, leading to problems such as broken strings and dropped wires, seriously threatening the safety and stability of the power grid. Traditional manual cleaning and maintenance methods are not only inefficient and costly but also carry significant safety risks. With the rapid development of drone technology, its application in power line inspection is gradually maturing. Drones can not only perform rapid and accurate insulator inspection but also clean and spray coating operations, effectively reducing the risk of flashover and significantly improving operational efficiency.

[0003] However, in existing cleaning or spraying equipment, the spray boom (or liquid spraying boom) is quite long, making drones prone to collisions and damage when flying within the factory area. Therefore, improvements to the existing technology are necessary.

[0004] Currently, the search yielded a Chinese patent titled "Insulator Cleaning Machine and Insulator Cleaning Method," publication number CN114074087B.

[0005] The device includes a water path adjustment mechanism, a positioning mechanism, and a lifting mechanism. The water path adjustment mechanism comprises a water supply component and a nozzle. The water supply component supplies water to the nozzle. The nozzle is connected to the positioning mechanism, which adjusts the position and orientation of the nozzle. The water supply component is connected to the lifting mechanism, which adjusts the height of the water supply component. The lifting mechanism allows the water supply component to be adjusted to approximately the height around the insulator to be cleaned. The positioning mechanism independently controls the movement of the nozzle. Due to the relatively simple nozzle structure, the positioning mechanism provides precise, efficient, and flexible positioning, making it easy to operate and avoiding the problem of difficult nozzle control caused by a complex water path adjustment mechanism. However, this device cannot achieve the folding of the spray bar (or liquid spraying bar) used on drones.

[0006] The currently searched Chinese patent "A Folding Arm for a Drone and a Drone", publication number CN113928535A, includes a main arm and a slave arm in a sliding sleeve state. The main arm is also provided with a rotatable support foot. During the sliding sleeve process of the main arm and the slave arm, the support foot can rotate accordingly in a clockwise or counterclockwise direction. The first end of the slave arm is also provided with a rotatable folding rod, and the end of the folding rod is provided with a rotor. This drone folding arm can actively extend and shorten its arm length according to the usage needs of different environments. The extended arm length can improve the stability of the drone body during flight, avoid it from shaking or even falling due to environmental factors, and optimize the flight capability of the drone body. However, this device cannot realize the folding of the spraying rod (or liquid spraying rod) installed on the drone. Summary of the Invention

[0007] The purpose of this invention is to provide a folding spraying rod for cleaning and spraying PRTV on substation insulators, which solves the problem that the existing spraying rod, when installed under the drone, increases the collision length of the drone and makes it inconvenient to operate.

[0008] To achieve the above objectives, this utility model provides a folding spraying rod for cleaning and spraying PRTV on substation insulators, including a main control box. The main control box is characterized by: two symmetrically distributed boom rods fixedly connected to it; two symmetrically distributed connecting frames fixedly connected to the end of each boom rod away from the main control box; a motor box fixedly connected between the two connecting frames; two symmetrically distributed tilting discs connected to the outside of the motor box; a motor frame fixedly connected inside the motor box; and parallel tilting shafts and drive shafts mounted inside the motor frame via bearings. A servo motor is fixedly mounted on the outer side of the motor frame. Gear 1 is fixedly connected to the middle of the outer side of the tilting shaft. The free end of the tilting shaft extends out of the motor frame and is fixedly connected to the tilting disk. A worm gear is fixedly connected to the middle of the outer side of the drive shaft. A worm gear meshing with the worm gear is fixedly connected to the outer side of the output shaft of the servo motor. Gear 2 is fixedly connected to the outer side of the drive shaft. Gear 3 meshing with Gear 2 is installed inside the motor frame through a bearing. Gear 4 meshing with a first-step gear fixed coaxially with the gear is installed inside the motor frame through a bearing. Gear 1 meshes with a second-step gear fixed coaxially with Gear 4.

[0009] The working principle of this utility model is as follows: When no spraying or cleaning is required, the second arm can be rotated by the flipping disc. Rotating the second arm 150-180° allows it to be folded relative to the first arm, thus reducing the overall volume of the spraying rod. When spraying or cleaning is required, the drone equipped with this device (i.e., the main control box is mounted on the bottom of the drone with screws) flies to the predetermined position and starts the servo motor. The servo motor drives the worm gear to rotate. During the rotation of the worm gear, the worm wheel drives the drive shaft to rotate. The drive shaft drives the second gear to rotate. The second gear drives the third gear to rotate the fourth gear. The fourth gear drives the flipping shaft to rotate through the first gear. During the rotation of the flipping shaft, the second arm can be rotated by the flipping disc. When the second arm is coaxial with the first arm, i.e., the second arm is in the unfolded state, the self-locking property between the worm gear and the worm wheel limits the second arm, allowing the insulator to be sprayed with PRTV or sprayed with cleaning liquid or cleaning water.

[0010] Furthermore, each of the rotating discs is fixedly connected to a second mechanical arm, and a vector nozzle is fixedly connected to the end of the second mechanical arm away from the rotating disc.

[0011] Furthermore, the aforementioned servo motor is fixedly connected to the motor housing, the output shaft of the servo motor passes through the motor frame, and the output shaft of the servo motor and the motor frame can rotate relative to each other.

[0012] Furthermore, the aforementioned main control box, connecting frame, and flip plate are all made of insulating material.

[0013] Furthermore, the aforementioned main control box is connected to the drone.

[0014] Furthermore, the aforementioned boom rod consists of two parallel, spaced-apart rods.

[0015] Furthermore, the aforementioned boom rod 2 consists of two parallel and spaced rods. When the rotating disc flips and extends, boom rod 2 is coaxial with boom rod 1. When the rotating disc flips and folds, boom rod 2 and boom rod 1 are folded and stacked vertically.

[0016] Furthermore, the aforementioned connecting frame is a rigid body, and there is a channel between the two connecting frames for placing and fixing the motor box. A partial section of the motor box is embedded in the channel, and the partial section of the motor box extends out of the channel, with the flip plate installed on both sides of the extended part.

[0017] Furthermore, the side of the aforementioned connecting frame is provided with a slot for inserting and fixing the boom rod.

[0018] Furthermore, the side of the aforementioned tilting disc is provided with a slot for inserting and fixing the boom rod two.

[0019] The beneficial effects of this utility model are as follows: By adding structures such as a first arm stick, a flip disk, and a servo motor to the main control box, the second arm stick can be folded during the flight of the drone through the rotational connection between the flip disk and the connecting frame. After folding, the extension length of the spraying rod can be effectively reduced, which can reduce the probability of the spraying rod colliding and make the drone operation more convenient. At the same time, due to the design of the arm stick and the motor box, the weight of the spraying rod can be reduced, making the drone easier to fly. Attached Figure Description

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

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this embodiment provides a folding spraying rod for cleaning and spraying PRTV on substation insulators, including a main control box 1 that can be connected to a drone (not shown in the figure). The connection can be made by screws, bolts, etc. Two symmetrically distributed boom rods 2 are fixedly connected to the main control box 1 (boom rods 2 are two parallel and spaced rods, and the main control box 1 has a slot for fixing one end of the boom rod 2). Two symmetrically distributed connecting frames 3 are fixedly connected to the end of the boom rod 2 away from the main control box (the side of the connecting frame 3 is provided with a slot for inserting and fixing the other end of the boom rod 2).

[0028] A motor box 4 is fixedly connected between the two connecting frames 3. Two symmetrically distributed flip plates 5 are connected to the outside of the motor box 4. Specifically, the connecting frame 3 is a rigid body. There is a channel between the two connecting frames for placing and fixing the motor box 4. A part of the motor box 4 is embedded in the channel. The part of the motor box 4 extends out of the channel and the flip plates 5 are installed on both sides of the extended part.

[0029] The motor housing 4 has a motor frame 9 fixedly connected inside. Inside the motor frame 9, a rotating shaft 10 and a drive shaft 13 (and subsequently, shafts with gears 17 and a first-stage gear 19, and shafts with gear 18 and a second-stage gear 20) are mounted parallel to each other via bearings. A servo motor 11 is fixedly mounted on the outside of the motor frame 9. The output shaft of the servo motor 11 passes through the motor frame 9 and can rotate relative to the motor frame 9. Gear 12 is fixedly connected to the middle of the outer side (outer circumference) of the rotating shaft 10. The free end of the rotating shaft 10 extends out of the motor frame 9 and is fixedly connected to the rotating disk 5. A worm gear 14 is fixedly connected to the middle of the outer side (outer circumference) of the drive shaft 13. A worm 16, meshing with the worm gear 14, is fixedly connected to the outer side (outer end) of the servo motor's output shaft. The outer side (outer circumference) of the drive shaft 13 is fixedly connected to the middle of the drive shaft 13. A gear 15 is fixedly connected (the gear 15 is coaxial with the worm gear 14, but offset axially). Inside the motor frame 9, a gear 17 meshes with the gear 15 via bearings (specifically, the two ends of the shaft with the gear 17 are mounted inside the motor frame 9 via bearings; the motor frame 9 can be a rectangular slotted shell). Inside the motor frame, a gear 18 meshes with the first stepped gear 19, which is coaxially fixed with the gear 17 (specifically, the two ends of the shaft with the first stepped gear 19 and the gear 17 are mounted inside the motor frame 9 via bearings, and the first stepped gear 19 is coaxially fixed with the gear 17, and the gear 18 meshes with the first stepped gear 19). A gear 12 meshes with a second stepped gear 20, which is coaxially fixed with the gear 18 (specifically, the gear 18 and the second stepped gear 20 are coaxially fixed, and the gear 12 meshes with the second stepped gear 20).

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, each rotating disc 5 has a fixedly connected boom 6 inside. Specifically, the side of the rotating disc 5 has slots for inserting and fixing the boom 6. A vector nozzle 7 is fixedly connected to the end of the boom 6 away from the rotating disc 5. The vector nozzle 7 can spray or spray cleaning fluid or water onto the insulator. The boom 6 is specifically composed of two parallel, spaced-apart rods. When the rotating disc 5 rotates and extends (e.g., ...), ... Figure 1 , 3As shown), boom link 26 is coaxial with boom link 12. When the flipping disc 5 flips and folds, boom link 26 and boom link 12 are folded and stacked vertically (as shown). Figure 2 (As shown).

[0031] In the above-mentioned worm 16, the worm wheel 14 can drive the worm gear 14 to rotate, while the worm gear 14 cannot drive the worm 16 to rotate. Specifically, the self-locking function can be achieved by setting the helix angle between the worm gear 14 and the worm 16 (this design is existing technology and will not be elaborated here).

[0032] The aforementioned main control box, connecting frame, and flip plate can all be made of insulating materials.

[0033] One or two sets of position switches 8 can be fixedly installed on the upper flip plate 5. Figure 3 The diagram shows the schematic installation position of the position switch 8, not its absolute installation position. The position switch 8 is an existing component. It serves as the control switch for the servo motor 11; that is, when the position switch 8 is triggered, the servo motor 11 starts or stops operating. The position switch 8 is not a necessary component. When the position switch 8 is not used, due to the folding position of the boom lever 2 6 (e.g., ... Figure 2 (as shown) and extension station (such as) Figure 1 As shown, the number of rotations of the output shaft of the servo motor can be preset to achieve the switching between the two positions, that is, after the servo motor 11 receives the signal, it rotates forward or backward a certain number of times; the installation position of the position switch 8 can be the relative position of the flip plate 5 and the connecting frame 3 when the boom rod 2 6 is in the folding position or the extension position.

[0034] The working principle of this utility model is as follows: When no spraying or cleaning operation is required, the second arm can be rotated by the flip plate. Rotating the second arm 150-180° allows it to be folded relative to the first arm, thus reducing the overall volume of the spraying rod. When spraying or cleaning is required, the drone equipped with this device (i.e., the main control box is mounted on the bottom of the drone via screws) flies to the predetermined position, activates the servo motor 11, and the servo motor drives the worm gear 16 to rotate. During the rotation, the worm gear 16 drives the drive shaft 13 through the worm wheel 14. The drive shaft 13 rotates, driving gear 2 15 to rotate. Gear 2 15 drives gear 4 18 to rotate via gear 3 17. Gear 4 18 drives the rotating shaft 10 to rotate via gear 1 12. During the rotation, the rotating shaft 10 can rotate the boom 2 6 via the rotating disc 5. When boom 2 6 is coaxial with boom 1 2, that is, boom 2 6 and boom 1 2 are in the extended state, the boom 2 is limited by the self-locking property between the worm and the worm wheel, and then PRTV or cleaning liquid or cleaning water can be sprayed on the insulator.

[0035] The beneficial effects of this utility model are as follows: By adding structures such as the first arm stick 2, the flip disk 5, and the servo motor 11 to the main control box, the second arm stick 6 can be folded through the rotational connection between the flip disk 5 and the connecting frame 3 during the flight of the drone. After folding, the extension length of the spraying rod can be effectively reduced, which can reduce the probability of the spraying rod collision and make the drone operation more convenient. At the same time, due to the design of the arm stick and the motor box, the weight of the spraying rod can be reduced, making the drone easier to fly.
