Description

Technical Field

[0001] The present application relates to the field of power system maintenance, and in particular to a device and method for live cleaning of high-voltage primary equipment. Background Art

[0002] High-voltage equipment (such as transformers, switch cabinets, etc.) is exposed to the outdoors or complex industrial environments for a long time, and pollutants such as dust, oil, salt, and metal particles are easily accumulated on the surface. These pollutants will reduce the insulation performance of the equipment, increase the risk of faults such as flashover and short circuit, and threaten the safe operation of the power grid. Traditional cleaning methods require advance planning of power outages and coordination of load transfers, which makes the operation complicated and costly. Frequent power outages may affect equipment performance. Subsequently, manual spraying of cleaning fluid on the surface of the equipment with a nozzle is required for cleaning. This is inefficient and difficult to completely remove dirt on the complex structure of the equipment. At the same time, the sprayed cleaning fluid carries dust in the air and splashes, resulting in a harsh working environment and affecting personnel health. Summary of the invention

[0003] In order to improve the problem that the current high-voltage equipment cleaning method requires power off in advance, resulting in low cleaning efficiency and poor effect, as well as a harsh working environment, the present application provides a high-voltage primary equipment live cleaning device and method.

[0004] The present application provides a high-voltage primary equipment live cleaning device and method using the following technical solutions:

[0005] A live cleaning device for high-voltage primary equipment comprises a closed shell, wherein a movable cavity is provided inside the closed shell, wherein a plurality of movable transverse grooves are arranged through the side wall of the movable cavity in the front-to-back direction, wherein a plurality of movable transverse grooves are provided with circulation longitudinal grooves in the outer circumferential direction of the fixed side wall thereof, wherein the circulation longitudinal grooves extend from the front end to the rear end of the movable cavity to form a closed loop, wherein telescopic recesses are provided at both upper and lower ends of the plurality of movable transverse grooves, wherein longitudinal sealing plates for isolating the two ends of the movable transverse grooves are telescopically provided in the plurality of telescopic recesses, wherein transverse sealing plates for isolating the movable transverse grooves and the through openings of the longitudinal sealing plates are telescopically provided in the plurality of movable transverse grooves on one side of the longitudinal sealing plates and in the circulation longitudinal grooves;

[0006] A cleaning mechanism for cleaning high-voltage equipment is provided in the movable cavity, located in the through-opening of the movable transverse groove and the circulating longitudinal groove. The cleaning mechanism includes a connecting shell movably arranged in the movable transverse groove and the circulating longitudinal groove. A fixed shell for fixing to an external moving device is provided on one side of the connecting shell. A nozzle as a whole for electrically spraying the high-voltage equipment is provided on the other side of the fixed shell. A rotating rubber plate for wiping the surface of the high-voltage equipment is provided between the nozzle as a whole and the connecting shell.

[0007] By adopting the above technical solution, the fixed housing moves cyclically along the moving transverse groove and the circulating longitudinal groove, thereby passing by the electrical appliances and circuits on the surface of the high-voltage equipment. The whole nozzle sprays the cleaning liquid and moves back and forth, so as to clean the front and rear end surfaces of the high-voltage equipment. With the spraying of the whole nozzle, the wiping end of the rotating rubber plate is assisted to be blown. The rotating rubber plate rotates to wipe the surface of the equipment and is affected by the push, improving the wiping range and strength. Thus, an automated cleaning process is formed, improving the cleaning efficiency and cleaning effect. At the same time, the closed housing abuts against the high-voltage box body, thereby shielding the internal high-voltage equipment to form a sealed environment, preventing the internal dust mixture from splashing to the outside and contacting people, and providing a good working environment.

[0008] Preferably, a connecting block is fixedly arranged on the outer surface of the fixed housing away from the connecting housing. An operating cavity is opened inside the fixed housing. A rotating motor is fixedly arranged on one side inside the operating cavity. The output end of the rotating motor is fixedly provided with a rotating main rod. A balancing auxiliary rod is rotatably arranged on the other side of the rotating main rod inside the operating cavity. Synchronous wheels are fixedly arranged on the surfaces of the rotating main rod and the balancing auxiliary rod. Synchronous toothed belts are meshed on the surfaces of the two synchronous wheels.

[0009] One ends of the rotating main rod and the balancing auxiliary rod both movably penetrate through the fixed housing and are located outside, and driving wheels are fixedly arranged on the penetrated surfaces. The two driving wheels are both meshed and connected with the inner wall of the rotating rubber plate.

[0010] By adopting the above technical solution, the two synchronous wheels are meshed with the synchronous toothed belts, so that the rotating main rod drives the balancing auxiliary rod to rotate synchronously. The rotation of the rotating main rod and the balancing auxiliary rod drives the two driving wheels to be respectively meshed with both sides of the inner wall of the rotating rubber plate, thereby transmitting the rotational force of the rotating main rod and making the rotating rubber plate rotate along the inner wall of the connecting housing, providing the power for the wiping action.

[0011] Preferably, a reciprocating thread is arranged at one end of the rotating main rod away from the driving wheel. A reciprocating screw hole that is threadedly meshed with the reciprocating thread is opened at a position on the side surface of the whole nozzle aligned with the rotating main rod. A limiting ring is fixedly arranged at the penetrated end of the balancing auxiliary rod. A limiting hole into which the limiting ring is inserted is opened at a position on the side surface of the whole nozzle aligned with the balancing auxiliary rod.

[0012] By adopting the above technical solution, the reciprocating thread is threadedly connected with the reciprocating screw hole, so that the whole nozzle moves horizontally back and forth along the surface of the reciprocating thread with the rotation of the rotating main rod. At the same time, the limiting ring is inserted into the limiting hole to form a balanced support with the rotating main rod on both sides of the whole nozzle, and at the same time, the limiting ring is clamped in the limiting hole to form a limit, preventing the whole nozzle from sliding out of the reciprocating thread excessively.

[0013] Preferably, a rotating card slot is fixedly provided on one side surface of the fixed housing facing the connecting housing. A fixed card slot is protrudingly provided on one side of the connecting housing facing the fixed housing and sleeved on the outer surface of the rotating card slot. A rotating clamping ring that is clamped with the channel of the rotating card slot is protrudingly provided on one side of the rotating rubber plate facing the fixed housing. A brush for cleaning high-voltage equipment is fixedly provided on the other side of the rotating rubber plate relative to the rotating clamping ring.

[0014] By adopting the above technical solution, the fixed card slot is externally clamped with the rotating card slot, thereby forming an integral connection between the connecting housing and the fixed housing to prevent loosening. At the same time, the rotating clamping ring is rotatably arranged in the fixed card slot, thereby providing space for the rotation of the rotating rubber plate and limiting the rotating rubber plate to prevent the rotating rubber plate from falling off during rotation.

[0015] Preferably, a partition plate is fixedly provided at one end of the whole spray head facing the fixed housing. One end of the partition plate extends between the rotating main rod and the balancing auxiliary rod and penetrates through the fixed housing and is located in the operation cavity. An extrusion cavity channel is inwardly opened at the penetrating end of the partition plate.

[0016] By adopting the above technical solution, the partition plate penetrates through the operation cavity, so that the extrusion cavity channel is communicated with the cleaning liquid supply device. At the same time, the partition plate is located between the rotating main rod and the balancing auxiliary rod, forming a partitioning effect and providing an auxiliary supporting effect on the upper and lower ends of the inner wall of the rotating rubber plate.

[0017] Preferably, a compression spray head is fixedly provided on the side of the whole spray head away from the partition plate. An extrusion soft surface is provided on the side of the compression spray head facing the high-voltage equipment. A plurality of liquid spraying holes are annularly opened on the side surface of the extrusion soft surface. All the plurality of liquid spraying holes penetrate through the whole spray head and are communicated with the extrusion cavity channel.

[0018] By adopting the above technical solution, the liquid spraying holes are communicated with the extrusion cavity channel, so as to secondarily compress the cleaning liquid in the extrusion cavity channel, increase the spraying range and spraying force of the cleaning liquid. At the same time, the extrusion soft surface provided at the front end of the compression spray head effectively prevents damage to the high-voltage equipment caused by extrusion during the movement of the compression spray head. And as the extrusion soft surface is in contact with the equipment and the inner wall of the box and generates extrusion, the liquid spraying holes are compressed again, so that the sprayed cleaning liquid is triple-compressed to increase the spraying force.

[0019] Preferably, a storage tank for storing cleaning liquid is fixedly provided on one side of the bottom of the movable cavity. A pressure pump is fixedly provided on the top of the storage tank. The output end of the pressure pump is provided with a conveying pipeline. A pipeline opening is opened at a position in the operation cavity aligned with the extrusion cavity channel. The conveying pipeline penetrates through the pipeline opening and is communicated with the extrusion cavity channel.

[0020] By adopting the above technical solution, the pressure pump increases the pumping force and extracts the cleaning liquid in the storage tank and transports it into the conveying pipeline. The conveying pipeline is docked with the extrusion channel, and the extrusion channel is used to increase the flow rate of the cleaning liquid, thereby forming a conveying process of the cleaning liquid.

[0021] Preferably, a lateral driving mechanism is arranged on one side of the fixed housing in the movable cavity. The moving end of the lateral driving mechanism is connected to the connecting block, and a longitudinal driving mechanism for driving the lateral driving mechanism to move is fixedly arranged on one side of the lateral driving mechanism in the movable cavity.

[0022] By adopting the above technical solution, the longitudinal driving mechanism is connected to the lateral driving mechanism, and the lateral driving mechanism is connected to the connecting block, thereby forming an overall connection of the longitudinal driving mechanism, the lateral driving mechanism and the fixed housing, enabling the fixed housing to move along the moving transverse groove and the circulating longitudinal groove, and ensuring the cleaning range of the compression nozzle for the high-pressure box.

[0023] Preferably, a high-pressure box is arranged on one side of the closed housing. A discharge port for communicating the high-pressure box with the outside is opened at the bottom of the side surface of the closed housing, and a moving crawler for pushing the closed housing to move is arranged on the bottom surface of the closed housing.

[0024] By adopting the above technical solution, the discharge port is communicated with the inside of the high-pressure box, so as to receive the dripping cleaning liquid and dust and dirt, and discharge them to the outside along with the flow of the cleaning liquid. The moving crawler is located at the bottom of the closed housing, so as to facilitate the operator to push the closed housing to move to align with the high-pressure box to complete the cleaning operation.

[0025] A method for cleaning live high-voltage primary equipment, which is used for the above-mentioned ultrasonic-assisted ultrafast laser glass drilling device, includes the following steps:

[0026] S01. Push the whole closed housing to move to a state where it fits the surface of the high-pressure box. Then, the lateral driving mechanism drives the connecting block to move laterally along the moving transverse groove. When the connecting block moves to the longitudinal connection notch of the moving transverse groove, the longitudinal driving mechanism drives the lateral driving mechanism to make the connecting block move along the longitudinal connection notch. When the connecting block moves to the circulating longitudinal groove, the longitudinal driving mechanism drives the connecting block to move up and down to move to the initial position to form a circular movement;

[0027] During the movement of the connecting block along the moving transverse groove, it contacts and presses against a plurality of longitudinal sealing plates, thereby pressing the longitudinal sealing plates back into the telescopic notch. When the connecting block moves past, the longitudinal sealing plates are no longer under pressure and thus rebound to their original positions, and are spliced with another aligned longitudinal sealing plate to restore the sealed state. When the connecting block moves along the longitudinal connection notch and the circulating longitudinal groove of the moving transverse groove, it first contacts and presses against a plurality of transverse sealing plates laterally, thereby compressing the transverse sealing plates to reserve a moving space for the connecting block. Then, as the connecting block moves out, the transverse sealing plates rebound to restore the sealed state;

[0028] S02. The movement of the connecting block drives the connecting housing, the rotating rubber plate, and the nozzle as a whole to move integrally. Then, the rotating motor rotates the rotating main rod. The rotating main rod drives the balance auxiliary rod to rotate synchronously through the synchronous pulley and the synchronous toothed belt connected to the synchronous pulley, causing the two driving wheels to rotate. The two driving wheels drive the rotating rubber plate to rotate within the connecting housing, thereby driving the brush bristles to rotate around the nozzle as a whole to wipe off the dirt on the surface of the internal equipment of the high-pressure box.

[0029] S03. The pressure pump extracts the cleaning liquid from the storage tank and transports it to the extrusion chamber through the conveying pipeline. The extrusion chamber squeezes the cleaning liquid to narrow the flow range and increase the flow velocity. The cleaning liquid enters the liquid spraying holes and is sprayed on the surface of the internal equipment of the high-pressure box. And as the rotating main rod continues to rotate, the nozzle as a whole drives the compression nozzle to move back and forth along the reciprocating thread surface to spray and clean the front end face and the rear end face of the equipment circuit. As the compression nozzle reciprocates, the sprayed cleaning liquid generates a thrust on different positions of the surface of the brush bristles, increasing the wiping range of the brush bristles.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The closed housing is in contact with the high-pressure box to form a sealed cleaning environment, avoiding the bad working environment formed by the contact of the dust mixture with personnel and its scattering to the outside. At the same time, the cleaning mechanism moves in a cycle along the moving transverse groove and the circulating longitudinal groove to perform cleaning and wiping actions on the surface of the high-pressure equipment. The formed automatic cleaning method effectively improves the cleaning efficiency and reduces the maintenance cost.

[0032] 2. The rotating main rod drives the rotating rubber plate to rotate, so that the brush bristles wipe the surface of the high-pressure equipment. At the same time, the rotation of the rotating main rod drives the nozzle as a whole to move reciprocally, improving the cleaning range of the compression nozzle on the surface of the equipment, the wiring, and the back of the terminal. And as the nozzle as a whole moves, the extrusion soft surface is pressed against the high-pressure equipment, so that the cleaning liquid ejected from the liquid spraying holes is squeezed multiple times, thereby increasing the spraying intensity and improving the cleaning effect on the surface of the equipment. At the same time, the ejected cleaning liquid generates a thrust on the brush bristles, complementing each other to improve the wiping strength of the brush bristles and cleaning the dust attached to the surface of the brush bristles.

Detailed implementation manners

[0048] The following Figures 1-8 further elaborates on the present application in detail.

[0049] The embodiments of the present application disclose a live cleaning device and method for high-voltage primary equipment.

[0050] The "up, down, left, and right" perspectives of this device are Figure 2 based on the direction of the attached drawings.

[0051] Refer to Figures 1 to 4, a live cleaning device for high-voltage primary equipment, including a closed housing 1. A high-voltage box 16 is abutted against the front end face of the closed housing 1, and a layer of rubber material is fixedly provided on the front surface of the closed housing 1 to increase the abutting sealing performance with the high-voltage box 16. The opening width of the high-voltage box 16 is the same as the size of the front end face of the closed housing 1. When the closed housing 1 and the high-voltage box 16 are completely abutted, a sealed environment inside the high-voltage box 16 is formed. On the side of the closed housing 1 away from the high-voltage box 16, an activity cavity 2 is opened. A moving transverse groove 3 is penetrated through the side surface of the activity cavity 2. The whole moving transverse groove 3 is composed of multiple S shapes. And a circulating longitudinal groove 6 is opened on one side of the moving transverse groove 3 in the activity cavity 2. The upper and lower ends of the circulating longitudinal groove 6 are respectively communicated with the head and tail ends of the moving transverse groove 3 to form a circulating loop. At the same time, both the moving transverse groove 3 and the circulating longitudinal groove 6 penetrate through the activity cavity 2 to form the front and rear ends of the closed housing 1 to be communicated;

[0052] In the transverse groove of the moving transverse groove 3, telescopic notches 4 are inwardly opened at multiple upper and lower end faces. The multiple telescopic notches 4 are arranged in an up-and-down manner. Longitudinal sealing plates 7 are elastically arranged in the multiple telescopic notches 4. The longitudinal sealing plates 7 are diamond-shaped, and the diamond openings of every two layers of longitudinal sealing plates 7 are opposite to each other. On one side of each longitudinal sealing plate 7 facing the telescopic notch 4, a spring is fixedly provided, and the other end of the spring is fixedly connected to the bottom of the telescopic notch 4;

[0053] At the S-shaped bend of the moving transverse groove 3, at this time, the moving transverse groove 3 is in a longitudinal state. A transverse sealing plate 8 is fixedly provided on the side wall surface of the groove away from the longitudinal sealing plate 7. The outer surface of the transverse sealing plate 8 abuts against the inner wall of the moving transverse groove 3, and a bending and rebounding structure is arranged inside the transverse sealing plate 8, which can be stretched and compressed, and multiple transverse sealing plates 8 are arranged to perform transverse telescopic settings towards the longitudinal sealing plate 7.

[0054] It should be noted that a sliding door is opened on one side of the outer surface of the closed housing 1. The sliding door is used to open and close the connection with the activity cavity 2 to facilitate personnel to observe the internal situation of the device. A groove is opened on the lower end surface of the closed housing 1, and a moving track 15 is rotatably arranged in the groove. Cooperating with the grip provided on the closed housing 1 on the side of the sliding door, it is convenient for personnel to push the closed housing 1 to move to the high-voltage box 16 to be cleaned, improving flexibility. At the same time, a discharge port 14 is penetrated through the side surface of the closed housing 1 above the moving track 15. The inner channel of the discharge port 14 is inclined, and the inclined top is directly opposite to the bottom surface inside the high-voltage box 16, so as to facilitate the discharge of the cleaning liquid and dust mixture flowing down inside the high-voltage box 16 to the outside.

[0055] Refer to Figure 2 、 Figure 5 、 Figure 6, the cleaning mechanism 5 includes a fixed housing 52 movably arranged in the moving transverse groove 3 and the circulating longitudinal groove 6. The length and width dimensions of the fixed housing 52 are respectively consistent with the length of the moving transverse groove 3 and the width of the circulating longitudinal groove 6, so as to form a tightly abutted state between the fixed housing 52, the moving transverse groove 3 and the circulating longitudinal groove 6. A rotating clamping groove 524 is convexly arranged on the front end face of the fixed housing 52. The rotating clamping groove 524 is in a claw state, and a connecting housing 51 is sleeved on the overall outer surface of the rotating clamping groove 524. A fixed clamping groove 513 is fixedly arranged on the side surface of the connecting housing 51 facing the fixed housing 52. The inner wall of the fixed clamping groove 513 is sleeved and inserted with the outer surface of the rotating clamping groove 524, and the inner walls are tightly abutted. The rotating clamping groove 524 and the fixed clamping groove 513 adopt H7 / g6 fit. The width of the clamping groove is 30±0.01mm, and the outer diameter of the clamping ring 531 is 29.98mm, ensuring that it is neither loose nor stuck when rotating.

[0056] The inside of the connecting housing 51 is hollow, and an annular rotating rubber plate 53 is movably abutted on the inner wall surface of the connecting housing 51. The rotating rubber plate 53 is made of hydrogenated nitrile rubber, has hardness and can deform under pressure, thereby providing a deformation basis for rotating on the inner wall of the connecting housing 51. The inner surface of the rotating rubber plate 53 is convexly arranged with a tooth surface around it, and a rotating clamping ring 531 is fixedly arranged on the side surface of the rotating rubber plate 53 facing the fixed housing 52. The whole rotating clamping ring 531 is transversely clamped and fixed in the rotating clamping groove 524 (the rotating clamping ring 531 rotates actively in the rotating clamping groove 524 to drive the rotating rubber plate 53 to rotate synchronously);

[0057] A nozzle assembly 54 is inserted into the inside of the rotating rubber plate 53. A partition plate 543 is fixedly arranged on the side surface of the nozzle assembly 54 facing the fixed housing 52. The partition plate 543 extends horizontally from the inside of the rotating rubber plate 53 and is movably abutted against the upper and lower sides of the inner wall of the rotating clamping groove 524 (the end of the partition plate 543 movably penetrates through the inside of the fixed housing 52). The outer shell of the nozzle assembly 54 and all power transmission components adopt insulating materials with a voltage resistance of ≥10kV; The closing housing 1 and the high-voltage box 16 form a grounding connection, automatically test the electric field distribution before spraying, and automatically stop when the voltage fluctuation exceeds the limit (±5%);

[0058] Refer to Figure 3 、 Figure 7, on the side surface of the fixed housing 52 away from the connecting housing 51, a rectangular connecting block 522 is fixedly protruded. One end of the connecting block 522 extends into the moving cavity 2. Inside the moving cavity 2, a transverse driving mechanism 9 is movably arranged on one side of the connecting block 522. The connecting block 522 is threadedly connected to the end of the rotating rod in the transverse driving mechanism 9. The motor end of the transverse driving mechanism 9 movably penetrates through the closed housing 1 and is exposed outside for easy observation by personnel. Inside the moving cavity 2, a longitudinal driving mechanism 10 is fixedly arranged on one side of the transverse driving mechanism 9. And the rotating rod end of the longitudinal driving mechanism 10 is threadedly connected to the outer surface of the housing of the transverse driving mechanism 9;

[0059] Thus, a connection relationship is formed in which the longitudinal driving mechanism 10 drives the transverse driving mechanism 9 to move longitudinally, and the transverse driving mechanism 9 drives the connecting block 522 to move transversely. At the same time, a through groove is longitudinally opened on the outer surface of the closed housing 1 at the position where the motor of the transverse driving mechanism 9 penetrates, to prevent dislocation during the movement of the transverse driving mechanism 9.

[0060] It should be noted that a rigid limiting ring is provided at the inner end of the telescopic notch 4. One end of the spring is fixedly connected to the limiting ring, and the other end is fixedly connected to the bottom of the notch. The preloading force is set to XN to ensure that the longitudinal sealing plate 7 is in a fully closed state before contacting the connecting block 522; when the thrust of the connecting block exceeds YN, the longitudinal sealing plate 7 retracts into the notch.

[0061] Refer to Figures 6 to 8 , the inside of the fixed housing 52 is hollowed out to form an operating cavity 521. On one side of the inner wall of the operating cavity 521, a rotating motor 55 is fixedly arranged. The rotating end of the rotating motor 55 faces the direction of the connecting housing 51. And at the end of the rotating end of the rotating motor 55, a rotating main rod 56 is fixedly arranged. The end of the rotating main rod 56 away from the rotating motor 55 movably penetrates through the fixed housing 52 and is connected to the nozzle assembly 54. At the same time, inside the operating cavity 521, a balancing auxiliary rod 57 is rotatably arranged on one side of the rotating main rod 56. One end of the balancing auxiliary rod 57 also movably penetrates through the fixed housing 52 and is connected to the nozzle assembly 54. And on the parts of the rotating main rod 56 and the balancing auxiliary rod 57 located inside the operating cavity 521, synchronous wheels 58 are fixedly arranged on the surfaces. Synchronous toothed belts 59 are meshed and connected to the surfaces of the two synchronous wheels 58, thus forming a connection state in which the rotation of the rotating main rod 56 drives the synchronous rotation of the balancing auxiliary rod 57;

[0062] A tension pulley is added between the two synchronous pulleys 58 to ensure that the synchronous toothed belt 59 is always under uniform stress. The material is selected as a high-voltage electrostatic-resistant polyurethane belt with a service life of not less than 10,000 hours, and the tension is checked every 500 hours. Then, the penetrating ends of the main rod 56 and the balance auxiliary rod 57 are rotated, and a driving wheel 510 is fixedly installed on a part of the surface within the coverage of the connecting housing 51. The tooth surfaces of the two driving wheels 510 are meshed with the tooth surface of the rotating rubber plate 53, so that the driving wheel 510 drives the rotating rubber plate 53 to rotate along the inner surface of the connecting housing 51 during rotation. At the same time, brush hairs 532 are fixedly installed on the front side surfaces of the rotating rubber plate 53. As the rotating rubber plate 53 rotates, the brush hairs 532 are driven to rotate to wipe the surfaces of the equipment in the high-voltage box 16;

[0063] A reciprocating thread 512 is provided on the surface of the penetrating end of the rotating main rod 56. At the same time, a reciprocating screw hole 546 is opened inward at the position where the side surface of the overall nozzle 54 is aligned with the rotating main rod 56. The reciprocating screw hole 546 is threadedly connected with the reciprocating thread 512, and as the rotating main rod 56 rotates, the overall nozzle 54 moves horizontally back and forth along the surface of the reciprocating thread 512;

[0064] A limiting ring 511 is convexly fixed at the penetrating end of the balance auxiliary rod 57. A limiting hole 547 is opened inward at the position where the side surface of the overall nozzle 54 is aligned with the balance auxiliary rod 57. The opening width of the limiting hole 547 is the same as the width of the balance auxiliary rod 57, and the inner width of the limiting hole 547 is the same as that of the limiting ring 511 (the width of the limiting ring 511 is greater than the width of the balance auxiliary rod 57), so that the balance auxiliary rod 57 is inserted into the overall nozzle 54 for movement and limits the horizontal moving distance of the overall nozzle 54. The end of the limiting ring 511 and the end of the rotating main rod 56 are in a state of the same horizontal length.

[0065] Refer to Figures 6 to 8 As shown in the figure, the front end of the overall nozzle 54 protrudes and extends, and a compression nozzle 541 is fixedly installed at the extended end. The compression nozzle 541 is circular, and an extrusion soft surface 542 is fixedly installed at the front end of the compression nozzle 541. The extrusion soft surface 542 is made of soft ethylene propylene diene monomer rubber material, which has good weather resistance, chemical corrosion resistance and compressive resistance, so that the compression nozzle 541 unloads force when contacting the high-voltage equipment to avoid collision damage. At the same time, spray holes 545 are circumferentially and penetratingly opened on the outer surface of the compression nozzle 541. A plurality of spray holes 545 all penetrate through the inside of the overall nozzle 54 to form an extrusion cavity 544. The extrusion cavity 544 extends from the overall nozzle 54 into the partition plate 543 and penetrates through the end of the partition plate 543 to communicate with the operation cavity 521. The overall extrusion cavity 544 is in a double L-shaped bending state, so as to form an auxiliary extrusion effect during the transportation of the cleaning liquid;

[0066] The end of the extrusion chamber 544 is hermetically fixed with a conveying pipeline 13. The other end of the conveying pipeline 13 movably penetrates through the fixed housing 52 and is located in the movable chamber 2. At the position of the conveying pipeline 13 at the bottom inside the movable chamber 2, a storage tank 11 is fixedly provided. The cleaning liquid is stored inside the storage tank 11. The cleaning liquid uses a special charged cleaning agent, which has the characteristics of high insulation performance, strong decontamination ability, and flame retardancy. The upper end face of the storage tank 11 is fixedly provided with a pressure pump 12 by screws. The pressure pump 12 provides a suction pressure of 1 - 2 bar, and the extraction flow rate is not less than 5 L / min. The length, width, and height of the pressure pump 12 are set within 0.2 m × 0.3 m × 0.2 m. The input end of the pressure pump 12 is docked with the outlet end of the storage tank 11, and the output end of the pressure pump 12 is hermetically connected to the penetrating end of the conveying pipeline 13, so as to extract the storage tank 11 and convey it into the conveying pipeline 13.

[0067] It should be noted that a hose clamp and an NBR seal ring ≤ 0.5 mm are provided at the pipeline port 523 of the conveying pipeline 13, and the clamp torque is 5 N·m to ensure no leakage inside the conveying pipeline 13 under a 2 bar extraction power. The fixed housing 52 is provided with a pipeline port 523 at the penetrating position of the conveying pipeline 13. The pipeline port 523 and the conveying pipeline 13 are in an active insertion state, and the length of the conveying pipeline 13 has a reserved length of 0.3 - 0.5 m, so as to avoid pulling misalignment when the whole nozzle 54 moves horizontally out. At the same time, the length of the brush bristles 532 protrudes 3 - 5 cm from the surface of the extrusion soft surface 542, so as to ensure that the brush bristles 532 contact the surface of the high-voltage equipment prior to the extrusion soft surface 542.

[0068] Among them, the device also includes a rotating motor 55, a lateral driving mechanism 9, a longitudinal driving mechanism 10, a storage tank 11, a pressure pump 12, a high-voltage box 16, and a control system and circuit structure for electrically controlling the rotating motor 55, the lateral driving mechanism 9, the longitudinal driving mechanism 10, and the pressure pump 12 are all prior arts. The control system uses a PLC controller, equipped with a position encoder (installed on the rotating main rod 56) and a pressure sensor (installed on the conveying pipeline). Through the PID algorithm, the injection flow rate and rotation speed are adaptively adjusted to ensure the cleaning effect of equipment with different pollution degrees and balance the sealing pressure to avoid leakage. The fixed moving distances of the lateral driving mechanism 9 and the longitudinal driving mechanism 10 are adaptively adjusted based on the width dimensions of the moving transverse groove 3 and the circulating longitudinal groove 6. The rotation speed of the rotating motor 55 is set between 150 - 350 pm, so as to achieve 50 - 60 self-rotation wiping actions per minute of the rotating rubber plate 53.

[0069] Embodiment 2

[0070] Refer to Figures 1 to 8 , a method for live cleaning of high-voltage primary equipment, which is used for the above-mentioned live cleaning device of high-voltage primary equipment, and includes the following steps:

[0071] S01. First, the operator pushes the grip on one side of the closed housing 1, causing the closed housing 1 to move to one side of the high-voltage box 16 that needs to be cleaned. Then, the front opening of the closed housing 1 is tightly pressed against the door of the high-voltage box 16, so that a sealed state is formed between the closed housing 1 and the high-voltage box 16. Then, the transverse drive mechanism 9 drives the transverse connecting block 522 to move along the moving transverse groove 3. When the connecting block 522 moves to the S-shaped vertical bending part of the moving transverse groove 3,

[0072] The transverse drive mechanism 9 and the connecting block 522 are connected by a spline, and the longitudinal drive mechanism 10 and the housing of the transverse drive mechanism 9 are engaged through a lateral sliding groove. When longitudinal switching is required, first lock the spline of the transverse drive mechanism 9, then start the longitudinal drive mechanism 10 to make the whole transverse drive mechanism 9 move along the longitudinal groove. After completion, unlock the transverse spline, and then enable the transverse drive mechanism 9 to slide laterally, repeating this process, so as to complete the movement effect of the connecting block 522 along multiple moving transverse grooves 3. Then, when the connecting block 522 moves to the bottom of the moving transverse groove 3 and then enters the circulating longitudinal groove 6, the longitudinal drive mechanism 10 drives the housing of the transverse drive mechanism 9 to move upward, so that the connecting block 522 moves synchronously and finally moves back to its original position, thus forming a moving cycle;

[0073] When the connecting block 522 moves in the moving transverse groove 3, it contacts the longitudinally clamped longitudinal sealing plates 7. The connecting block 522 applies pressure from the inclined surface of the longitudinal sealing plate 7, causing both longitudinal sealing plates 7 to be pressed into the telescopic notch 4. When the connecting block 522 moves past, the two longitudinal sealing plates 7 lose the pressure they receive and protrude again along the telescopic notch 4 and abut against each other. When the connecting block 522 moves to the longitudinal connecting notch in the moving transverse groove 3 and the circulating longitudinal groove 6, at this time, the connecting block 522 first moves laterally, and during the lateral movement, it squeezes the transverse sealing plate 8 to compress it, thus opening up the longitudinal movement space for the connecting block 522. As the connecting block 522 moves downward and then moves out of the longitudinal notch or the circulating longitudinal groove 6, the connecting block 522 cancels the pressure applied to the transverse sealing plate 8, so that the transverse sealing plate 8 rebounds and abuts against the side wall again to form a seal, thus forming the seal of the entire moving transverse groove 3 and the circulating longitudinal groove 6 to prevent dust mixture from entering the device interior;

[0074] S02. As the connecting block 522 moves, it drives the fixed housing 52 to move, and then the connecting housing 51, the rotating rubber plate 53, and the entire nozzle 54 that are integrally fixed to the fixed housing 52 all move synchronously. During the movement of the connecting block 522, the rotating motor 55 drives the rotating main rod 56 to rotate. The rotation of the rotating main rod 56 drives the synchronous pulley 58 to rotate. Through the meshing connection of the synchronous toothed belt 59, the balance auxiliary rod 57 rotates synchronously with the rotating main rod 56. At this time, the rotating main rod 56 and the balance auxiliary rod 57 rotate to drive the two driving wheels 510 to rotate in the same direction. Furthermore, the tooth surface of the driving wheel 510 meshes and abuts against the tooth surface of the rotating rubber plate 53, driving the rotating rubber plate 53 to rotate. Moreover, both sides of the inner wall of the rotating rubber plate 53 mesh with the two driving wheels 510 to form a supporting effect. At the same time, the middle part of the inner wall of the rotating rubber plate 53 abuts against the upper and lower ends of the partition plate 543. Thus, the rotating rubber plate 53 rotates around the inner surface of the connecting housing 51 to form a self-rotation movement as a whole. As the rotating rubber plate 53 rotates, it drives the bristles 532 to rotate to wipe the surface of the high-voltage equipment;

[0075] S03. During the movement of the connecting block 522, the pressure pump 12 operates to extract the special charged cleaning agent in the storage tank 11 and transports it to the conveying pipeline 13 from the output end of the pressure pump 12. The special charged cleaning agent is input into the extrusion chamber 544 along the conveying pipeline 13 and is extruded by the L-shaped chamber, thereby initially increasing the flow rate. Then it enters the compression nozzle 541 and is sprayed onto the surface of the high-voltage equipment through the liquid spraying holes 545. During the process of passing through the liquid spraying holes 545, due to the dispersion of multiple nozzles and the fact that the size of the nozzles is smaller than the width of the extrusion chamber 544, a secondary compression occurs to increase the spraying speed. At this time, as the rotating main rod 56 rotates, it drives the reciprocating thread 512 to rotate within the reciprocating screw hole 546. Furthermore, the entire nozzle 54 is subjected to the rotational force of the reciprocating thread 512. Then the entire nozzle 54 moves reciprocally along the surface of the reciprocating thread 512;

[0076] As the entire nozzle 54 moves reciprocally, the special charged cleaning agent sprayed from the compression nozzle 541 comes into contact with the rotating bristles 532. While increasing the wiping effect by attaching the special charged cleaning agent to the bristles 532, it also cleans the dust on the surface of the bristles 532. And as the compression nozzle 541 reciprocally moves and sprays, it generates an outward thrust on the bristles 532. The surface of the bristles 532 is subjected to the back-and-forth thrust to form a wavy outward swinging action, thereby improving the wiping effect on the surface of the high-voltage equipment;

[0077] Meanwhile, the entire nozzle 54 reciprocates to generate a spraying action from top to bottom on the surface of the high-voltage equipment. When the entire nozzle 54 is extended and located on the surface of the high-voltage equipment, it sprays on the wiring outside the high-voltage equipment and the back of the conductive terminals, increasing the cleaning angle. And when the entire nozzle 54 abuts against the surface of the high-voltage equipment, the soft surface 542 is squeezed to relieve the force and prevent impact damage to the equipment. And with the squeezing of the soft surface 542, the orifice of the liquid spraying hole 545 deforms, thereby increasing the spraying force and flow rate of the special live cleaning agent three times, effectively cleaning the dust adhering to the surface of the high-voltage equipment. Finally, the special live cleaning agent and the dust mixture fall off from the surface of the high-voltage equipment and are discharged to the outside through the discharge port 14. Thus, the spraying of the liquid spraying hole 545 cooperates with the wave wiping action of the brush bristles 532 to form an effect of comprehensively cleaning the surface of the high-voltage equipment.

[0078] The above are only optional embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

10. A method for live cleaning of high-voltage primary equipment, which is used for a high-voltage primary equipment live cleaning device according to any one of claims 1 to 9, characterized in that: Including the following steps: S01. Push the entire closed housing (1) to move integrally until it fits against the surface of the high-pressure box (16). Then, the lateral drive mechanism (9) drives the connecting block (522) to move laterally along the moving transverse groove (3). When the connecting block (522) moves to the longitudinal connecting notch of the moving transverse groove (3), the longitudinal drive mechanism (10) drives the lateral drive mechanism (9) to move the connecting block (522) along the longitudinal connecting notch. When the connecting block (522) moves to the circulating longitudinal groove (6), the longitudinal drive mechanism (10) drives the connecting block (522) to move up and down and then move to the initial position to form a circulating movement. During the movement of the connecting block (522) along the moving transverse groove (3), it contacts and presses against multiple longitudinal sealing plates (7), thereby pressing the longitudinal sealing plates (7) back into the telescopic notch (4). When the connecting block (522) moves past, the longitudinal sealing plates (7) are no longer under pressure and thus rebound to their original positions and are spliced with another aligned longitudinal sealing plate (7) to restore the sealed state. When the connecting block (522) moves along the longitudinal connecting notch and the circulating longitudinal groove (6) of the moving transverse groove (3), it first contacts and presses against multiple transverse sealing plates (8) laterally, thereby compressing the transverse sealing plates (8) to reserve a moving space for the connecting block (522). Then, as the connecting block (522) moves out, the transverse sealing plates (8) rebound to restore the sealed state. S02. The movement of the connecting block (522) drives the connecting housing (51), the rotating rubber plate (53), and the entire nozzle (54) to form an integral movement. Then, the rotating motor (55) rotates the rotating main rod (56), and the rotating main rod (56) drives the balance auxiliary rod (57) to rotate synchronously through the synchronous pulley (58) and the synchronous toothed belt (59) connected to the synchronous pulley (58), causing the two driving wheels (510) to rotate. The two driving wheels (510) drive the rotating rubber plate (53) to rotate within the connecting housing (51), thereby driving the bristles (532) to rotate around the entire nozzle (54) to wipe the dirt on the surface of the equipment inside the high-pressure box (16). S03. The pressure pump (12) extracts the cleaning liquid from the storage tank (11) and transports it through the delivery pipe (13) into the extrusion chamber (544). The extrusion chamber (544) squeezes the cleaning liquid to reduce the flow range and increase the flow velocity. The cleaning liquid enters the liquid spraying holes (545) and is sprayed on the surface of the equipment inside the high-pressure box (16). And as the rotating main rod (56) continues to rotate, the entire nozzle (54) drives the compression nozzle (541) to move back and forth along the surface of the reciprocating thread (512) to spray and clean the front and rear end faces of the equipment circuit. As the compression nozzle (541) reciprocates, the sprayed cleaning liquid generates a thrust on different positions of the surface of the bristles (532), increasing the wiping range of the bristles (532).
