Description

Technical Field

[0001] The present application relates to the technical field of power transmission line cleaning, and in particular to a cleaning device for power transmission line insulators. Background Art

[0002] Transmission line insulators are important components in the power system that support and fix conductors and prevent them from coming into contact with other objects, such as the ground or metal towers. The main function of transmission line insulators is insulation, ensuring that current does not leak and preventing power system failures. In order to prevent leakage, improve insulation performance, extend equipment life, and improve power supply reliability, workers need to regularly clean the dirt on transmission line insulators to ensure the normal operation of the insulators.

[0003] However, currently, the method for cleaning transmission line insulators is usually manual cleaning, which is performed by workers climbing high or using special equipment, such as aerial work vehicles and aerial work frames. During the cleaning process, workers need to use tools such as brushes, towels, and rags, combined with water, detergents, etc. to remove dirt on the surface of the insulators. Although manual cleaning can clean areas with severe local pollution and can determine the health status of insulators through manual inspection, it is a high-altitude operation, so the safety risks are greater and the efficiency is lower.

[0059] See also Figure 1 as well as Figure 2 One embodiment of the present application provides a cleaning device for a transmission line insulator. Specifically, the cleaning device of one embodiment includes a drone 11, a cleaning mechanism 20, and a cleaning mechanism 30. The drone 11 can be selectively connected to the cleaning mechanism 20 or the cleaning mechanism 30. Figure 4 The cleaning mechanism 20 includes a water tank 21, a water pump 22 and a water outlet pipe. The water tank 21 is used to store water. The water tank 21 is detachably connected to the drone 11. The water pump 22 connects the water tank 21 and the water outlet pipe. The water outlet pipe is used to spray water in the water tank 21 under the drive of the water pump 22. Figure 5 The cleaning mechanism 30 includes a connecting shell 31, a driving component 32 and a cleaning brush 33. The connecting shell 31 is detachably connected to the drone 11. The driving component 32 is arranged on the connecting shell 31 and connected to the cleaning brush 33. The cleaning brush 33 can move under the drive of the driving component 32.

[0060] Specifically, when it is necessary to clean the insulator of the transmission line, the cleaning mechanism 20 is first connected to the drone 11, and then the drone 11 can be controlled to drive the cleaning mechanism 20 to fly to the insulator to be cleaned, and then the water pump 22 connected to the water tank 21 is started. The water pump 22 pumps water out of the water tank 21 and sprays it to the insulator through the outlet pipe to rinse the insulator. When the insulator needs to be further cleaned, the drone 11 can be controlled to land first and the connected cleaning mechanism 20 can be removed, and then the cleaning mechanism 30 can be connected and fixed to the drone 11, and then the drone 11 can be controlled again to drive the cleaning mechanism 30 to fly to the insulator to be cleaned, and the cleaning brush 33 can be driven by the driving component 32 to move on the surface of the insulator, so that the insulator can be cleaned, and finally the dirt on the transmission line insulator can be cleaned.

[0061] In the above-mentioned cleaning device for transmission line insulators, the cleaning mechanism 20 or the cleaning mechanism 30 is used to clean or clean the insulators at high places by using the drone 11, without the need for manual tower climbing, avoiding the workers' high-altitude operations, reducing the labor intensity of the workers, and improving the safety and efficiency of cleaning the transmission line insulators. And because the drone 11 can be selectively connected to the cleaning mechanism 20 or the cleaning mechanism 30, it is possible to flexibly choose to carry the cleaning mechanism 20 or the cleaning mechanism 30 on the drone 11 according to the dirtiness of the insulator, so as to realize the insulators to be cleaned separately, or cleaned separately, or cleaned first and then cleaned, or cleaned first or cleaned again, etc., thereby improving the use flexibility of the cleaning device. And compared with carrying the cleaning mechanism 20 and the cleaning mechanism 30 at the same time, the drone 11 of the cleaning device of the present application only carries the cleaning mechanism 20 or the cleaning mechanism 30 separately each time, which can reduce the lift demand for the drone 11, thereby reducing the cost. And when the drone 11 carries the cleaning mechanism 20 alone, it can choose a water tank 21 with a larger capacity, thereby improving the cleaning endurance. When the cleaning mechanism 30 is installed alone, a cleaning brush 33 with a larger area can be selected to improve the cleaning efficiency.

[0062] See also Figure 3 In one embodiment, the drone 11 is provided with a first quick-release assembly 40, combined with Figure 4 as well as Figure 5 The water tank 21 and the connecting shell 31 are both provided with a second quick-release assembly 50, and the first quick-release assembly 40 can be selectively connected to the second quick-release assembly 50 on the water tank 21 or the second quick-release assembly 50 on the connecting shell 31. In this way, through the cooperation of the first quick-release assembly 40 and the second quick-release assembly 50, the cleaning mechanism 20 and the sweeping mechanism 30 on the drone 11 can be quickly disassembled and assembled, further improving the work efficiency.

[0063] Specifically, see Figure 6In one embodiment, the first quick-release assembly 40 includes a mounting block 41, a clamping block 42, a first elastic member 43, and a first pull rod 44. The mounting block 41 is fixed to the bottom of the drone 11. The mounting block 41 is provided with a cavity 411. The cavity 411 passes through one end of the mounting block 41 away from the drone 11. The cavity wall of the cavity 411 is provided with an escape cavity 412. The clamping block 42 is movably disposed in the escape cavity 412. The clamping block 42 has a locking position and an unlocking position. In the locking position, at least a portion of the clamping block 42 penetrates into the cavity 411. In the unlocking position, the clamping block 42 exits the cavity 411 and is accommodated in the escape cavity 412. One end of the first elastic member 43 is connected to the cavity wall of the escape cavity 412, and the other end of the first elastic member 43 is connected to the clamping block 42. The elastic force of the first elastic member 43 is used to drive the clamping block 42 to maintain the locking position. One end of the first pull rod 44 is connected to the block 42, and the other end of the first pull rod 44 is movably passed through the side wall of the mounting block 41, and the first pull rod 44 is used to drive the block 42 to enter the unlocking position. Exemplarily, the block 42 can be a wedge-shaped structure, and the side of the block 42 facing away from the drone 11 has an inclined surface.

[0064] Further, see Figure 6 The second quick-release assembly 50 includes a mounting bar 51, a second pull rod 53, and a fixing block 52. The mounting bar 51 is fixed to the water tank 21 or the connecting shell 31. The second pull rod 53 is movably arranged on the mounting bar 51. The fixing block 52 is provided with a card slot 521. The fixing block 52 is connected to one end of the second pull rod 53. The fixing block 52 can enter the cavity 411 under the drive of the second pull rod 53. When the fixing block 52 enters the preset position in the cavity 411, the card slot 521 can be opposite to the avoidance cavity 412. The card block 42 can enter the locking position under the drive of the first elastic member 43 and penetrate into the card slot 521, so that the card block 42 is fixedly engaged with the fixing block 52.

[0065] Specifically, when it is necessary to connect the cleaning mechanism 30 or the washing mechanism 20 to the drone 11, the corresponding fixing block 52 is first inserted into the cavity 411, and then the second pull rod 53 is pushed upward to drive the fixing block 52 into the cavity 411. During this process, the fixing block 52 will first contact the inclined surface of the card block 42. As the fixing block 52 continues to enter the cavity 411, the fixing block 52 will gradually squeeze the card block 42, so that the card block 42 retreats to the avoidance cavity 412 and enters the avoidance position. During this process, the first elastic member 43 is compressed. When the fixing block 52 continues to enter the cavity 411 to the position where the slot 521 and the avoidance cavity 412 are opposite, the block 42 can be pushed into the slot 521 under the elastic force of the first elastic member 43, that is, the block 42 enters the locked position. At this time, the block 42 is engaged and fixed with the fixing block 52, thereby realizing the connection and fixation between the drone 11 and the cleaning mechanism 30 or the cleaning mechanism 20. The operation is convenient and labor-saving, and no other tools are required, which is highly efficient.

[0066] When it is necessary to remove the cleaning mechanism 30 or the cleaning mechanism 20 from the drone 11, by pulling the first pull rod 44 outward, the first pull rod 44 can drive the block 42 to retract into the avoidance cavity 412, that is, the block 42 enters the unlocking position, at this time the block 42 withdraws from the slot 521, and the connection between the fixing block 52 and the block 42 is released, and then the fixing block 52 is pulled out of the cavity 411, so that the cleaning mechanism 30 or the cleaning mechanism 20 can be removed from the drone 11. The operation is convenient and labor-saving, no other tools are required, and the efficiency is high.

[0067] Continue to see Figure 6 Optionally, in one embodiment, a positioning block 54 is convexly provided on the mounting strip 51, and the second pull rod 53 is also passed through the positioning block 54. A positioning groove 413 whose shape matches that of the positioning block 54 is also provided at the end of the mounting block 41 away from the drone 11. The positioning groove 413 is communicated with the cavity 411, and the positioning block 54 can be inserted into the positioning groove 413. Specifically, when installing the cleaning mechanism 30 or the washing mechanism 20, the positioning block 54 is first inserted into the positioning groove 413, which can achieve a pre-positioning effect, ensure that the fixing block 52 can accurately enter the cavity 411, and improve the convenience of installation.

[0068] Optionally, in one embodiment, a stop ring 55 is provided on the second pull rod 53, and a second elastic member 56 is sleeved on the second pull rod 53, one end of the second elastic member 56 is connected to the stop ring 55, and the other end of the second elastic member 56 is connected to the mounting bar 51, and the elastic force of the second elastic member 56 is used to drive the second pull rod 53 to move in the direction of exiting the cavity 411. In this way, when installing the cleaning mechanism 30 or the cleaning mechanism 20, pushing the second pull rod 53 upward can compress the second elastic member 56. When it is necessary to remove the cleaning mechanism 30 or the cleaning mechanism 20 from the drone 11, after pulling the first pull rod 44 until the block 42 exits the slot 521, the elastic force of the second elastic member 56 can drive the second pull rod 53 and the fixed block 52 to move in the direction of exiting the cavity 411, so that the fixed block 52 is reset, and it is prevented that the block 42 is reinserted into the fixed block 52 after the first pull rod 44 is released. At this time, the cleaning mechanism 30 or the cleaning mechanism 20 can be removed from the drone 11, and the convenience of disassembly is improved.

[0069] See also Figure 6In one embodiment, the wall of the avoidance cavity 412 is provided with a guide column 45, which extends in a direction close to the cavity 411 and passes through the block 42, the block 42 and the guide column 45 move and cooperate, and the first elastic member 43 is sleeved on the guide column 45. The guiding effect of the guide column 45 can improve the movement stability of the block 42. At the same time, the guide column 45 will also limit the first elastic member 43, so as to avoid bending of the first elastic member 43 when it is compressed, so as to ensure the working stability of the first elastic member 43. Furthermore, there are multiple guide columns 45, such as two, three, four or more, and each guide column 45 is provided with the first elastic member 43, so as to improve the movement stability of the block 42.

[0070] Further, there are a plurality of first quick-release assemblies 40, which are arranged at intervals on the bottom wall of the drone 11. For example, four first quick-release assemblies 40 are arranged on the bottom wall of the drone 11. Correspondingly, there are a plurality of second quick-release assemblies 50, which are used to be connected to the first quick-release assemblies 40 in a one-to-one correspondence, thereby improving the connection stability.

[0071] It is understandable that in other embodiments, the first quick-release assembly 40 and the second quick-release assembly 50 may also be magnetic quick-release structures or snap-on quick-release structures, which are not limited herein.

[0072] Optionally, in one embodiment, the cleaning mechanism 20 further includes a first telescopic component, the first telescopic component is arranged on the water tank 21, the water outlet pipe includes a water spray pipe 232 and a connecting hose 231, one end of the connecting hose 231 is connected to the water pump 22, the other end of the connecting hose 231 is connected to the water spray pipe 232, the other end of the water spray pipe 232 forms a water outlet, the water spray pipe 232 is arranged on the first telescopic component, and the water spray pipe 232 can reciprocate along the first direction under the drive of the first telescopic component. In this way, the water spray pipe 232 is driven to telescopically move by the first telescopic component, so that the water outlet of the water spray pipe 232 is close to the insulator, ensuring that the water spray pipe 232 sprays water at the insulator, thereby improving the cleaning efficiency.

[0073] See also Figure 4In one embodiment, the first telescopic assembly includes a first motor 242, a first screw 243, a guide plate 241, and a moving block 244. The first motor 242 is disposed on the water tank 21; the first screw 243 is connected to the output shaft of the first motor 242; the guide plate 241 is disposed on the water tank 21 and extends along the first direction; the moving block 244 is movably disposed on the guide plate 241 and is threadedly connected to the first screw 243; the moving block 244 can reciprocate along the guide plate 241 under the drive of the first screw 243; and the water spray pipe 232 is connected to the moving block 244. In this way, by driving the first screw 243 to rotate through the first motor 242, the moving block 244 can be driven to move along the guide plate 241, thereby driving the water spray pipe 232 to telescopically move.

[0074] Optionally, in one embodiment, the cleaning mechanism 30 further includes a second telescopic component, which is disposed on the connection shell 31 and connected to the driving component 32, and the second telescopic component is used to drive the driving component 32 and the cleaning brush 33 to reciprocate along the first direction. Specifically, when the drone 11 carrying the cleaning mechanism 30 flies to the vicinity of the insulator to be cleaned, the second telescopic component is used to drive the driving component 32 and the cleaning brush 33 to extend, so that the cleaning brush 33 can be abutted against the insulator, and then the driving component 32 is used to drive the cleaning brush 33 to move on the surface of the insulator, so as to clean the dirt on the insulator.

[0075] See also Figure 7 In one embodiment, the second telescopic assembly includes a second motor 341, a second screw rod 342, a movable sleeve 342, a support plate 344 and a limit plate 346, wherein the second motor 341 is fixed to one end of the connecting shell 31, and the output shaft of the second motor 341 penetrates into the connecting shell 31. The second screw rod 342 is arranged in the connecting shell 31, and one end of the second screw rod 342 is connected to the output shaft of the second motor 341. The movable sleeve 342 is sleeved on the second screw rod 342 and is threadedly connected with the second screw rod 342, and one end of the movable sleeve 342 penetrates from one end of the connecting shell 31 away from the second motor 341. The support plate 344 is connected to one end of the movable sleeve 342 that penetrates from the connecting shell 31, and the support plate 344 is connected to the driving assembly 32. The bottom wall of the connecting shell 31 is provided with a slide rail 345, and the slide rail 345 extends along the first direction. The limit plate 346 is movably connected to the slide rail 345, and the limit plate 346 is also fixedly connected to the support plate 344.

[0076] Specifically, the second motor 341 drives the second screw 342 to rotate, which can drive the movable sleeve 342 to move telescopically along the second screw 342, and the movable sleeve 342 then drives the driving assembly 32 and the cleaning brush 33 to move telescopically. At the same time, the limit plate 346 and the slide rail 345 are slidably matched, and the limit plate 346 is used to ensure that the movable sleeve 342 will not rotate with the second screw 342, so that the movable sleeve 342 drives the support plate 344 to move in a direction parallel to the second screw 342, and finally drives the driving assembly and the cleaning brush 33 to move.

[0077] See also Figure 7 In one embodiment, the driving assembly 32 includes a housing 321, a third motor 322, a first bevel gear 324 and a second bevel gear 325. The housing 321 is connected to the second telescopic assembly. Exemplarily, a clamping member 35 is connected to the support plate 344 of the second telescopic assembly, and the clamping member 35 is clamped on the housing 321. The third motor 322 is disposed in the housing 321, and the output shaft of the third motor 322 is connected to the first bevel gear 324, and the second bevel gear 325 is rotatably disposed in the housing 321, and the second bevel gear 325 is meshed with the first bevel gear 324, and the second bevel gear 325 is connected to the axle 326, and the axle 326 is perpendicular to the output shaft of the third motor 322, and one end of the axle 326 passes through the housing 321 and is connected to the cleaning brush 33. In this way, the third motor 322 drives the first bevel gear 324 to rotate, which can drive the second bevel gear 325 and the axle 326 on the second bevel gear 325 to rotate, and finally drive the cleaning brush 33 to rotate to clean the dirt on the insulator. And because the axle 326 on the second bevel gear 325 is perpendicular to the output shaft of the third motor 322, the direction of the torque output by the third motor 322 can be changed, so that the circumference of the cleaning brush 33 cleans the insulator, improving the cleaning effect.

[0078] Optionally, the cleaning brush 33 may be a hair brush, a cloth brush, a rubber brush, etc., which is not limited here.

A receiving space for receiving the cleaning mechanism 20 or the cleaning mechanism 30 is formed between the two legs 12. The legs 12 can be used to support the drone 11 when the drone 11 lands and when the cleaning mechanism 20 and the cleaning device are replaced.
