Description

Technical Field

[0001] The present invention relates to the technical field of laser cleaning, and in particular to online non-destructive cleaning equipment and a method for power disconnect switches based on laser technology. Background Art

[0002] The power isolating switch is a device used to disconnect the circuit in the power system. It is usually used in power facilities such as power lines and substations to ensure the safe disconnection of the circuit during inspection or maintenance. Its main function is to disconnect the circuit and isolate the current so that other parts of the power system can be inspected and maintained. The power isolating switch is generally equipped with a visible disconnect position indicator, which can intuitively determine whether it is in the disconnected state. Since the power isolating switch is exposed to the external environment for a long time, a large amount of dust, dirt and oxides will accumulate on its surface. These dirts not only affect the appearance of the equipment, but also may cause the electrical performance to decline and increase the risk of equipment failure. Therefore, it is very important to regularly clean the surface of the power isolating switch and remove surface dust and impurities to ensure the normal operation of the power isolating switch.

[0003] However, the existing cleaning technology for power disconnectors mainly relies on the traditional water flushing method. Although this method can clean some surface dirt, it usually requires the power disconnector to be shut down for cleaning, which results in a long period of equipment shutdown. Shutdown cleaning not only affects the operating efficiency of the power system, but also increases the maintenance cost and downtime of power facilities, resulting in unnecessary economic losses. In addition, water flushing may bring residual moisture, resulting in the risk of equipment corrosion and electrical short circuit, which brings potential safety hazards to the power system.

[0017] The method for online non-destructive cleaning of power disconnect switches based on laser technology comprises the following steps:

[0018] Move the base close to the power disconnect switch;

[0019] The driving motor 1 drives the support arm 1 away from the base, and then the driving motor 2 drives the support arm 2 away from the base, so that the bracket is close to the power isolating switch, and the driving motor 3 drives the cross arm and the bracket to rotate, so that the bracket and the power isolating switch are in a state of being parallel to each other;

[0025] The invention provides online non-destructive cleaning equipment and method for power isolating switches based on laser technology.

[0026] It has the following beneficial effects:

[0027] 1. The present invention utilizes a lifting mechanism to drive the support block, the moving mechanism and the laser head to move up and down along the power isolating switch, and utilizes the moving mechanism to drive the laser head to move horizontally in an arc in a direction perpendicular to the power isolating switch. Therefore, it is possible to achieve contactless cleaning of the outer wall of the power isolating switch without contacting it, and further, to achieve online cleaning without interrupting the operation of the power isolating switch, thereby preventing power grid accidents caused by heating of the isolating switch, effectively extending the service life of the power isolating switch, and improving the power supply reliability of the power system.

[0028] 2. The present invention can drive arm 1 and arm 2 to approach or move away from the base respectively by driving motor 1 and motor 2.

[0029] 3. The present invention can adjust gear two to rotate by driving motor six, and gear two can drive gear three to rotate. At this time, gear three can further drive the support shaft, folding arm, lifting mechanism, moving mechanism and laser head to rotate along the support shaft as the rotation axis, and then cooperate with the lifting mechanism and the moving mechanism to move the laser head, so that the moving path of the laser head can completely cover the outer wall of the power isolating switch, thereby improving the cleaning quality of the power isolating switch and preventing the residue of dust and rust.

[0030] 4. The present invention can support arm 1 by utilizing the card seat. Therefore, when the folding arm is folded, the card seat will be squeezed by arm 1, and then the pressure plate will be pressed into the base, and the inclined rod will squeeze the push block and the push rod, and then the push rod will push the support block out. At this time, the bottom of the bracket will contact the top of the support block, and then the support block can be used to support the bracket, thereby improving the stability of the bracket and the supporting effect of the bracket.

When the laser head 6 is close to the power isolating switch, the lifting mechanism 4 can be used to drive the support block 404 and the laser head 6 to reciprocate in the vertical direction, and the moving mechanism 5 can be used to drive the laser head 6 to reciprocate in the horizontal direction, and the arc plate 503 can be used to make the laser head 6 move in an arc, and the laser head 6 can be used to remove dust and rust on the outer wall of the power isolating switch, thereby realizing non-contact cleaning of the power isolating switch.

[0047] Please refer to the attached Figure 7-Figure 9 The moving mechanism 5 includes a motor 501, which is fixedly connected to the middle of the bottom surface of the support block 404. The output end of the motor 501 is fixedly connected to a gear 1 502. The arc plate 503 is slidably connected to the middle of the top surface of the support block 404. The bottom surface of the arc plate 503 is fixedly connected to a tooth 504. The gear 1 502 is meshed with the tooth 504. The middle of the top surface of the arc plate 503 is fixedly connected to a mounting box 505. The laser head 6 is installed in the middle of the mounting box 505. The side wall of the arc plate 503 is fixedly connected to a support bar 507. The ends of both sides of the arc plate 503 are fixedly connected to baffles 506. A slide groove 510 is opened in the middle of the top surface of the support block 404. The arc plate 503 and the support bar 507 are slidably connected inside the slide groove 510. An opening 511 is formed in the middle of the bottom surface of the slide slot 510 , and the top of the gear 1 502 passes through the opening 511 and meshes with the teeth 504 .

[0048] In this embodiment, the driving motor 501 can drive the gear 502 to rotate. At this time, the gear 502 can drive the teeth 504 and then the arc plate 503 drives the installation box 505 and the laser head 6 to slide inside the support block 404 along with the arc plate 503, thereby realizing the arc movement of the laser head 6, and the support bar 507 can be used to assist in supporting the arc plate 503 to avoid friction between the teeth 504 and the inner wall of the slide groove 510.

[0049] Please refer to the attached Figure 6-Figure 8 The lifting mechanism 4 includes a motor 401, which is fixedly connected to the middle of the bottom surface of the bracket 3. The output end of the motor 401 is fixedly connected to a threaded rod 402, which is rotatably connected to the middle of the bracket 3. The outer wall of the threaded rod 402 is threadedly connected to a slider 403, which is slidably connected to the inside of the bracket 3, and one side of the slider 403 is fixedly connected to the support block 404.

[0050] In this embodiment, the threaded rod 402 can be driven to rotate by driving the fourth motor 401, and the threaded rod 402 can be used to drive the slider 403 to slide inside the bracket 3. At this time, the slider 403 can be used to drive the support block 404 to move.

[0051] Please refer to the attached Fig.10 Fans 509 are fixedly connected to both sides of one side of the installation box 505, and filters 508 are provided on one side of the fans 509 on both sides, and the rotation directions of the fans 509 on both sides are opposite.

[0052] In this embodiment, when the laser head 6 cleans the power isolating switch, the two fans 509 can be driven to operate simultaneously. Since the two fans 509 rotate in opposite directions, the fan 509 on one side can deliver the external airflow to the inside of the installation box 505, while the fan 509 on the other side can draw the air inside the installation box 505, thereby realizing the circulation of the airflow, and further achieving the purpose of air cooling and heat dissipation of the laser head 6. In addition, the filter 508 can be used to filter impurities in the external air to prevent dust from entering the installation box 505 and affecting the normal operation of the laser head 6.

[0053] Please refer to the attached Figure 1 , Figure 2 , Figure 5 and Fig.11The folding arm 2 includes a support 201, which is installed on one side of the top surface of the base 1, and the middle part of the support 201 is rotatably connected to an arm 1 203, and a motor 1 202 is installed on one side of the support 201, and the output end of the motor 1 202 is fixedly connected to the bottom of the arm 1 203, and the outer wall at the top of the arm 1 203 is fixedly connected to a motor 2 204, and the middle part of the top of the arm 1 203 is rotatably connected to an arm 2 205, and the output end of the motor 204 is fixedly connected to the bottom of the arm 205, and the outer wall at the top of the arm 205 is fixedly connected to a motor 3 206, and the middle part of the top of the arm 205 is rotatably connected to a cross arm 207, and the output end of the motor 3 206 is fixedly connected to one side of the cross arm 207, and the other side of the cross arm 207 is fixedly connected to one side of the bracket 3.

[0054] In this embodiment, the driving motor can drive the support arm 1 203 to rotate, so that the top of the support arm 1 203 can be moved closer to or away from the base 1, and the driving motor 204 can drive the support arm 2 205 to rotate, so that the top of the support arm 2 205 can be moved closer to or away from the base 1. When the support arm 1 203 and the support arm 2 205 are away from the base 1 at the same time, the height of the bracket 3 will be raised. When the support arm 1 203 and the support arm 2 205 are close to the base 1 at the same time, the height of the bracket 3 will be lowered, and the support arm 2 205 can enter the interior of the support arm 1 203, thereby realizing the folding of the support arm 1 203 and the support arm 2 205.

[0055] Please refer to the attached Figure 5 A support shaft 9 is fixedly connected to the middle of the bottom surface of the support 201, and a gear three 10 is installed at the bottom of the support shaft 9. The support shaft 9 and the gear three 10 are both arranged inside the base 1. A motor six 7 is installed in the middle of the base 1, and a gear two 8 is fixedly connected to the output end of the motor six 7. The gear two 8 and the gear three 10 are meshingly connected.

[0056] In this embodiment, the driving motor six 7 can drive the gear three 10 to rotate, and the gear three 10 can drive the gear two 8 to rotate, and the gear two 8 can drive the support shaft 9 to rotate the support 201, and then the support 201 can drive the folding arm 2, the bracket 3, the lifting mechanism 4 and the moving mechanism 5 to rotate along the support shaft 9 as the rotation axis. At this time, the coverage area of ​​the moving path of the laser head 6 can be further expanded, thereby improving the effect of cleaning the outer wall of the power isolating switch.

[0057] Please refer to the attached Figure 2-Figure 4A pressure plate 11 is slidably connected to the other side of the top surface of the base 1, and a support rod 12 is rotatably connected to the top of the pressure plate 11. A holder 13 is fixedly connected to the outer wall of the support rod 12, and a roller 14 is rotatably connected to the inside of the holder 13. The inner wall of the holder 13 contacts the outer wall of the support arm 203, and a support rod 2 15 is fixedly connected to the bottom of the pressure plate 11. An inclined rod 16 is rotatably connected to the outer wall of the inclined rod 16, and a push block 17 is rotatably connected to the bottom of the inclined rod 16.

The top of the support block 19 contacts the bottom of the outer wall of the bracket 3. A limiting plate 20 is fixedly connected to the middle part of the outer wall of the push rod 18. A spring 21 is sleeved on one side of the outer wall of the push rod 18 close to the support block 19, and the spring 21, the limiting plate 20, the push rod 18, the push block 17 and the inclined rod 16 are all arranged inside the base 1.

[0058] In this embodiment, when the support arm 203 approaches the base 1, the support arm 203 will first contact the roller 14 inside the base 13. The rotation of the roller 14 can avoid mutual friction between the support arm 203 and the base 13. As the support arm 203 continues to approach the base 1, the support arm 203 will squeeze the base 13, and the base 13 will squeeze the pressure plate 11 to make it enter the inside of the base 1. Then, the pressure plate 11 will further squeeze the inclined rod 16 through the support rod 2 15. The inclined rod 16 can push the push block 17 to push the push rod 18 to move inside the base 1. At this time, the support block 19 can be pushed out, and then the support block 19 can be used to support the bottom of the bracket 3 to achieve the folding of the device.

[0059] This embodiment also provides a method for using the above device, including the following steps:

[0060] The mobile base 1 is close to the power isolating switch;

[0061] The driving motor 1 202 drives the arm 1 203 away from the base 1, and then the driving motor 2 204 drives the arm 2 205 away from the base 1, so that the bracket 3 is close to the power isolating switch, and the driving motor 3 206 drives the cross arm 207 and the bracket 3 to rotate, so that the bracket 3 and the power isolating switch are in a state of being parallel to each other;

[0062] The laser head 6 is driven to generate laser to clean the outside of the power isolating switch;

[0063] During cleaning, the drive motor 401 drives the threaded rod 402 to rotate, and the threaded rod 402 drives the slider 403, the support block 404, the moving mechanism 5 and the laser head 6 to move along the central axis of the power isolating switch; at the same time, the drive motor 501 drives the gear 1 502 to rotate, and the gear 1 502 drives the teeth 504 to drive the installation box 505 and the laser head 6 to slide inside the support block 404 along with the arc plate 503, so that the laser head 6 moves in an arc shape;

[0064] While the laser head 6 moves in an arc shape, the driving motor 6 7 drives the gear 2 8 to rotate, and the gear 2 8 drives the gear 3 10 and the support shaft 9 to rotate, and then the support shaft 9 drives the folding arm 2, the bracket 3, the lifting mechanism 4, the moving mechanism 5 and the laser head 6 to rotate along the support shaft 9 as the rotation axis, so that the moving path of the laser head 6 covers the outer wall of the power isolation switch, and non-contact cleaning is performed;

[0065] During cleaning, the two fans 509 are driven to rotate. Since the two fans 509 rotate in opposite directions, one fan 509 can blow air into the installation box 505, and the other fan 509 can extract the air inside the installation box 505, so as to realize air circulation and dissipate heat for the laser head 6.

[0066] After use, the driving motor 204 is reversed to fold the arm 205 into the arm 1 203, and the driving motor 1 202 is reversed to make the arm 1 203 close to the base 1. At this time, the arm 1 203 squeezes the seat 13 and then presses the pressure plate 11 into the interior of the base 1. At this time, the support rod 2 15 squeezes the inclined rod 16, and then the inclined rod 16 pushes the push block 17 to the top of the push rod 18. At this time, the limit plate 20 will squeeze the spring 21, and the push rod 18 will push the support block 19 out. Finally, the bracket 3 will contact the top of the support block 19 with the displacement of the arm 1 203 and the arm 2 205.

[0067] Working principle: When in use, first move the base 1 to make it close to the power isolating switch that needs to be cleaned. After it is close, drive the motor 1 202 to drive one side of the arm 1 203 to rotate along the middle of the support 201 as the rotation axis. At this time, the other side of the arm 1 203 will drive the arm 2 205 away from the base 1. Then drive the motor 204 again. At this time, the bottom of the arm 205 can be rotated along the top of the arm 1 203 as the rotation axis. At this time, the top of the arm 205, the bracket 3 and the laser head 6 will be away from the base 1 together. At this time, the height of the laser head 6 will be raised, and then it will be close to the power isolating switch;

[0068] After getting close, the driving motor three 206 drives the cross arm 207 and the bracket 3 to rotate, so that the bracket 3 and the power isolating switch are in a state of being parallel to each other. At this time, the laser head 6 can be driven to generate laser to clean the outside of the power isolating switch, and at the same time, the driving motor four 401 drives the threaded rod 402 to rotate, and the threaded rod 402 can drive the slider 403 to slide inside the bracket 3, and the driving motor four 401 is used to rotate forward and reverse. At this time, the moving mechanism 5 and the laser head 6 can reciprocate in the vertical direction along the power isolating switch, and the driving motor five 501 can also drive the gear one 502 to rotate and then move the teeth 504 to make the arc plate 503 slide inside the support block 404, and the driving motor five 501 is used to rotate forward and reverse, which can drive the installation box 505 and the laser head 6 to reciprocate in the horizontal direction with the arc plate 503. At this time, the laser head 6 can move in an arc shape, thereby cleaning the outer wall of the power isolating switch;

[0069] During the movement of the laser head 6, the gear 2 8 can be driven to rotate by driving the motor 6 7, and the gear 2 8 can drive the gear 3 10 and the support shaft 9 to rotate. At this time, the support shaft 9 can drive the folding arm 2, the bracket 3, the lifting mechanism 4, the moving mechanism 5 and the laser head 6 to rotate along the support shaft 9 as the rotation axis, so that the moving path of the laser head 6 covers the outer wall of the power isolating switch, and the power isolating switch is cleaned in an all-round non-contact manner;

[0070] During the operation of the laser head 6, the two fans 509 are driven to rotate simultaneously. Since the rotation directions of the two fans 509 are opposite, one fan 509 can blow air into the installation box 505, and the other fan 509 can extract the air inside the installation box 505, thereby realizing the circulation of air in the installation box 505, thereby realizing the heat dissipation of the laser head 6.

[0071] After use, the second support arm 205 is folded into the inside of the first support arm 203 by driving the second motor 204 in reverse, and then the first motor 202 is driven in reverse to make the first support arm 203 close to the base 1. When the first support arm 203 is close to the base 1, it will squeeze the card seat 13 and press the pressure plate 11 into the inside of the base 1. When the first support arm 203 contacts the card seat 13, since the card seat 13 is rotatably connected to the pressure plate 11 through the support rod 12, the card seat 13 will rotate along the support rod 12 as the rotation axis to match the angle between the first support arm 203 and the base 1. The rotation of the roller 14 can avoid the outer wall of the first support arm 203 and the inner wall of the card seat 13 from rubbing against each other, and the pressure plate 11 After being pressed into the interior of the base 1, it will synchronously drive the support rod 2 15 to move downward and then squeeze the inclined rod 16. At this time, the top of the inclined rod 16 will rotate along the support rod 2 15 as the rotation axis, and then the inclined rod 16 will push the push block 17 to the top of the push rod 18. At this time, the limit plate 20 will squeeze the spring 21, and the push rod 18 will push the support block 19 out. Finally, the bracket 3 will contact the top of the support block 19 with the displacement of the support arm 1 203 and the support arm 2 205. When used next time, when the support arm 1 203 is away from the base 1, the spring 21 will stretch, and then extend the limit plate 20 to drive the push rod 18 to squeeze the push block 17, and then the push block 17 squeezes the inclined rod 16 and the pressure plate 11 to reset it.
