Description

Technical Field

[0001] This invention relates to the field of power transmission equipment technology, specifically to a cleaning device for suspension insulators in digital substations. Background Technology

[0002] An insulator is a special type of insulating component that forms the main body of the insulation for power transmission lines. Its function is to suspend the conductors and keep them insulated from the towers and the ground. Because pollutants and particulate matter from the external environment can easily accumulate on the surface of the insulator, reducing its insulation performance and potentially leading to faults in the power distribution lines, workers need to clean the dust off the surface of the insulators.

[0003] The existing cleaning method involves maintenance personnel climbing to the top of the pole, then using a telescopic pole to move the cleaning device to the bottom of the insulator, and finally activating the disc brush of the cleaning device to clean the surface of the insulator.

[0004] However, the following problems exist in the use of suspension insulator cleaning devices in digital substations:

[0005] 1. When maintenance personnel need to climb to the top of the pole, their position is generally fixed. Therefore, when cleaning the insulators, the disc brush can only clean one side of the insulator and cannot clean the surface of the insulator from all sides. The cleaning effect is not ideal unless the maintenance personnel need to change their position to clean, which increases their labor intensity.

[0006] 2. Secondly, the insulators on the cable are generally of different sizes. Therefore, when the maintenance personnel encounter larger insulators with their disc brushes, the disc brushes need to clean from the edge of the insulator for a long time, which increases their labor intensity. When the maintenance personnel encounter smaller insulators with their disc brushes, the fixed disc brushes cannot clean from the gaps between the insulators better, resulting in poor cleaning effect.

[0007] 3. The existing insulator suspension installation methods are different. The suspension installation methods can be divided into vertical suspension, inclined suspension and horizontal suspension. However, when cleaning the insulator manually, the disc brush needs to be swept along the suspension direction of the insulator, which increases the difficulty of cleaning and increases the labor intensity of maintenance personnel. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a digital substation suspension insulator cleaning device. The structural design of this digital substation suspension insulator cleaning device can effectively solve the problems of poor insulator cleaning effect, increased labor intensity, inability to better clean insulators of different sizes, and increased cleaning difficulty due to the cleaning angle.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a digital substation suspension insulator cleaning device, comprising a fixed block, a semi-arc seat one mounted on the front rear end of the fixed block, a semi-arc seat two rotatably mounted on the rear rear end of the fixed block, a plurality of brush discs arranged in a circular array between the semi-arc seat one and the semi-arc seat two, brushes mounted on the outer side walls of the plurality of brush discs, a rotating component for driving the semi-arc seat two to rotate at the right end of the fixed block, a driving component for driving the entire brush disc to rotate at the bottom of the fixed block, an adjusting component for adjusting the spacing between the brush discs at the top of the fixed block, and a rotating component for driving the semi-arc seat one and the semi-arc seat two to move intermittently between the hand handle and the fixed block.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. This invention uses a rotating component to drive the second semi-arc seat to open and rotate along the first semi-arc seat. Then, the internal brushes of the first and second semi-arc seats perform all-round cleaning along the surface of the insulator. Compared with existing technologies, the cleaning effect of this invention is more comprehensive. Moreover, it only requires the first and second semi-arc seats to be moved slowly along the insulator for cleaning, without having to go around the edge of the insulator for cleaning. Furthermore, the brushes of this invention can be equipped with long bristles and short bristles so that they can fit and clean the curved edge of the insulator, thereby improving the surface cleaning effect of the insulator.

[0012] 2. The adjustment component of this invention allows manual adjustment of the rotation of the manual adjustment gear. Then, through the mutual linkage between the auxiliary adjustment gear, adjustment roller, auxiliary roller, connecting transmission belt, and fixed disc, the brush disc of each group is driven to move away from or closer to the insulator, so that insulators of different sizes and brushes can be brought closer together. This solves the problem of insulators of different sizes not being able to be cleaned synchronously, improves the applicability of this invention, and reduces the labor intensity.

[0013] 3. This invention reduces the difficulty and intensity of cleaning by setting up a rotating component that allows manual rotation of a gear. Then, through the mutual linkage between the drive block, tilting block, L-shaped block, fixed limit rod, and transmission screw, the fixed block is driven to move along the direction of the suspended insulator.

[0014] 4. The present invention, through the cooperation of the arc-shaped seat, slider, fixed plate, L-shaped rod, rotating block, bending rod and bending compression spring, allows the fixed block to slide intermittently along the arc-shaped seat, thereby enabling each group of brushes to achieve all-round cleaning.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, a digital substation suspension insulator cleaning device includes a handheld rod 1, a fixing block 2 at the top of the handheld rod 1, a semi-circular seat 3 mounted on the front of the rear end of the fixing block 2, and a second semi-circular seat 4 rotatably mounted on the rear end of the fixing block 2. Both the first and second semi-circular seats 3 and 4 have magnets attracting each other at their rear ends. A plurality of brush discs 5 arranged in a circular array are provided between the first and second semi-circular seats 3 and 4. Brushes are mounted on the outer walls of the brush discs 5. A rotating component 6 for driving the second semi-circular seat 4 to rotate is provided at the right end of the fixing block 2. The rotating component 6 includes a U-shaped frame 61 mounted on the right end of the fixing block 2. A drive rod 62 is rotatably connected to the side of the frame 61 away from the fixed block 2. An electric push rod 64 is rotatably connected to the side of the frame 61 close to the fixed block 2. A fixed ear 63 is installed in the middle of the drive rod 62. The moving end of the electric push rod 64 is rotatably connected to the inside of the fixed ear 63. A drive frame 65 is rotatably connected to the outer wall of the right end of the fixed block 2. The side of the drive frame 65 away from the fixed block 2 is rotatably connected to the upper and lower sides of the semi-arc seat 4. The brush has long bristles 511 and short bristles 512. The long bristles 511 are installed on the brush plate 5 located at the top, and the short bristles 512 are installed on the brush plate 5 located at the bottom.

[0030] During operation, firstly, the maintenance personnel move the hand-held rod 1 to one side of the insulator, using the semi-arc seat 3 and semi-arc seat 4 to surround the insulator. Then, the electric push rod 64 is driven to move up and down, causing the drive rod 62 to rotate from the inside of the mortise frame 61. At this time, the drive rod 62 drives the drive frame 65 to open and rotate from the fixed block 2, thereby causing the semi-arc seat 4 to move along the direction of the semi-arc seat 3. Finally, they are magnetically connected. When it is necessary to open the semi-arc seat 4, the moving end of the electric push rod 64 drives the fixed lug 63 to retract. At the same time, the drive frame 65 and the drive rod 62 retract horizontally, which helps to increase the opening degree between the semi-arc seat 3 and semi-arc seat 4, so that the semi-arc seat 3 and semi-arc seat 4 can surround the insulator from all directions. It also facilitates better folding of the mortise frame 61, drive rod 62, fixed lug 63, electric push rod 64 and drive frame 65, which serves as a storage function.

[0031] It is worth noting that the long bristles 511 and short bristles 512 provided in this invention are designed to allow the long bristles 511 and short bristles 512 to adhere to and clean the arc-shaped edge of the insulator, thereby improving the surface cleaning effect of the insulator.

[0032] Example 2:

[0033] like Figure 3 , Figure 5 , Figure 6 Figure 7 As shown, the bottom of the fixed block 2 is provided with a driving component 7 for driving the entire brush disc 5 to rotate. The driving component 7 includes a driving gear 71 set on the bottom end face of the fixed block 2. A main motor (not shown in the figure) is installed on the inner side of the fixed block 2 to make the driving gear 71 rotate. The front bottom walls of the semi-circular seat 1 3 and the semi-circular seat 2 4 are rotatably connected to the auxiliary gear 72. The bottom walls of the semi-circular seat 1 3 and the semi-circular seat 2 4 are rotatably connected to a plurality of semi-circular driving rollers 73. The bottom walls of the semi-circular seat 1 3 and the semi-circular seat 2 4 and the adjacent driving rollers 73 are rotatably connected to the auxiliary rollers 75. The conveyor belt 1 74 and the auxiliary roller 75 are also connected to the auxiliary rollers 75. The outer wall of the auxiliary roller 75 is connected to a conveyor belt 74. The top of the drive roller 73 near the fixed block 2 is fixedly connected to the auxiliary gear 72. The inner side of the semi-arc seat 3 and the semi-arc seat 4 corresponds to the brush disk 5 of each group and is rotatably connected to a fixed disc 51. The fixed disc 51 is mounted on the side away from the semi-arc seat 3 and the semi-arc seat 4 and is mounted on a rotating block 50. The inner side of the brush disk 5 is rotatably connected to the upper and lower ends of the rotating block 50 through a rotating shaft. The inner side of each group of rotating blocks 50 is provided with two drive rollers 76. The outer side of the two drive rollers 76 is connected to a conveyor belt 77.

[0034] During operation, the main motor inside the drive fixed block 2 drives the drive gear 71 connected to it to rotate, thereby driving the auxiliary gears 72 on both sides to rotate synchronously. At this time, through the cooperation of the conveyor belt 74 and the auxiliary roller 75, the drive roller 73 on the entire semi-arc seat 3 and the semi-arc seat 4 is driven to rotate. Through the rotational pressure of the drive roller 73 and the cooperation of the conveyor belt 77, the drive roller 76 inside the rotating block 50 is driven to rotate. In turn, through the rotating shaft, the upper and lower brush discs 5 of the rotating block 50 are driven to rotate, so that the brushes of each group can clean the insulator from all directions, improving the cleaning effect.

[0035] Example 3:

[0036] like Figure 6 , Figure 7 and Figure 8As shown, the driving component 7 also includes an arc-shaped seat 711 mounted on the top of the handheld lever 1. The top of the arc-shaped seat 711 has a cross groove. A slider 712 is slidably mounted on the inner side of the arc-shaped seat 711 and located in the cross groove. A fixing plate 713 fixedly connected to the fixing block 2 is mounted on the top of the slider 712. An L-shaped rod 714 is mounted on the rear side of the horizontal end of the slider 712. A rotating block 715 that abuts against the vertical end of the L-shaped rod 714 is mounted on the bottom of the driving gear 71. A curved rod 716 fixedly connected to the slider 712 is slidably mounted on the left end of the arc-shaped seat 711. A curved compression spring 717 is sleeved on the outer side of the curved rod 716. Curved grooves are opened on the upper and lower sides of the horizontal end of the slider 712. Multiple small balls 718 are rotatably connected in each group of curved grooves at the horizontal end of the cross groove. A large ball 719 rotatably connected to the slider 712 is rotatably connected to the bottom of the vertical end of the cross groove.

[0037] During the rotation of the drive gear 71, it drives the connected rotating block 715 to rotate. The rotating block 715 then drives the L-shaped rod 714 to slide along the arc-shaped seat 711. Subsequently, the slider 712 drives the bent rod 716 to move intermittently along the right side. At this time, the bending compression spring 717 enters a compressed state, and the fixing plate 713 drives the fixing block 2 to rotate intermittently from the arc direction of the arc-shaped seat 711. This ensures that when the semi-arc seat 1 3 and semi-arc seat 2 4 are fitted onto the large insulator, the area between the brushes on the brush disk 5 lacks a cleaning section. Therefore, the L-shaped rod 714 drives the fixed plate 713 to intermittently transmit power, thereby driving the semi-arc seat 1 3 and semi-arc seat 2 4 to rotate in a limited position along the arc seat 711, thus solving the problem of the parts that need cleaning. When the rotating block 715 and the L-shaped rod 714 enter the disengaged state, the bending compression spring 717 releases elastic potential energy, causing the bending rod 716 to drive the slider 712 to return to its original position. At this time, the brush disk 5 returns to its original position to clean the edge of the insulator again. Through continuous intermittent movement, the cleaning effect is further improved.

[0038] It is worth noting that the center points of the arc-shaped seat 711, the semi-arc seat 3, and the semi-arc seat 4 are at the same point, so that the semi-arc seat 3 and the semi-arc seat 4 can rotate along the center line of the insulator.

[0039] It is worth noting that rubber pads are laid on the outer sides of the L-shaped rod 714 and the rotating block 715 to prevent noise caused by the impact of the rotating block 715 on the L-shaped rod 714 and to improve the service life of the L-shaped rod 714 and the rotating block 715.

[0040] It is worth noting that the small ball 718 and the large ball 719 provided in this invention are intended to reduce the friction between the slider 712 and the arc-shaped seat 711, while improving the sliding performance of the slider 712 on the arc-shaped seat 711.

[0041] Example 4:

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the top of the fixed block 2 is provided with an adjustment component 8 for adjusting the spacing between the brush discs 5. The adjustment component 8 is provided with a manual adjustment gear 81 on the top of the fixed block 2. A manual torsion bar 83 is installed on the top of the manual adjustment gear 81. The front ends of the semi-arc seat 1 3 and the semi-arc seat 2 4 are rotatably connected to an auxiliary adjustment gear 82 that meshes with the manual torsion bar 83. The fixed disc parts 51 corresponding to the top of the semi-arc seat 1 3 and the semi-arc seat 2 4 are rotatably connected to an adjustment roller 84. The inner side of the adjustment roller 84 is fixedly connected to the top of the fixed disc part 51 through a rotating shaft. The top of the semi-arc seat 1 3 and the semi-arc seat 2 4 and located between adjacent adjustment rollers 84 are rotatably connected to an auxiliary adjustment gear 82. A connecting transmission belt 86 is connected between the auxiliary roller 85, the adjusting roller 84, and the auxiliary roller 85. The adjusting roller 84 and the auxiliary adjusting gear 82 located at the front end of the semi-arc seat 3 and the semi-arc seat 4 are fixedly connected. A U-shaped rod 811 is installed on the top of the fixed block 2 and at the front end of the manual adjusting gear 81. A pull rod 813 is slidably connected to the middle of the U-shaped rod 811. A locking gear plate 814 is installed at the bottom of the pull rod 813 to abut against the teeth of the manual adjusting gear 81. The left and right ends of the locking gear plate 814 and the horizontal end of the U-shaped rod 811 are slidably connected. An expansion spring 812 that compresses the locking gear plate 814 is sleeved on the horizontal end of the U-shaped rod 811.

[0043] During operation, when the spacing between the brush discs 5 needs to be adjusted, the maintenance personnel pull the lever 813 upwards with one hand. As the locking gear plate 814 moves upwards, the expansion spring 812 is compressed, causing the locking gear plate 814 to disengage from the teeth of the manual adjustment gear 81. The maintenance personnel then rotate the manual torsion lever 83 with the other hand, causing the manual adjustment gear 81 to drive the auxiliary adjustment gears 82 on both sides to rotate synchronously. With the cooperation of the auxiliary roller 85, the adjustment roller 84, and the connecting transmission belt 86, the auxiliary adjustment gear 82 drives the entire adjustment roller 84 to rotate until the spacing between each set of brush discs 5 is in contact with the insulator. Then, the lever 813 is released, allowing the locking gear plate 814 to press against the corresponding teeth of the manual adjustment gear 81 again. This solves the problem of synchronous cleaning of insulators of different sizes, improves the applicability of the invention, and reduces labor intensity.

[0044] Example 5:

[0045] like Figure 1 and Figure 9As shown, a rotating assembly 9 is provided between the handheld lever 1 and the fixed block 2 for driving the intermittent movement of the semi-arc seat 3 and the semi-arc seat 4. The rotating assembly 9 includes a driving rotating block 91. A rotating rod is installed at the front end of the fixed block 2, and the front end of the rotating rod rotates through the middle of the fixed plate 713 and is fixedly connected to the driving rotating block 91. A limit groove 90 is opened at the front end of the driving rotating block 91. A transmission groove is opened at the top of the handheld lever 1. An L-shaped block 93 is provided in the transmission groove. An inclined block 92 is installed at the vertical end of the L-shaped block 93, and a limit rod is installed at the end of the inclined block 92 away from the L-shaped block 93, which is inside the limit groove 90. A fixed limit rod 94 is installed in the transmission groove and is slidably connected to the L-shaped block 93. A transmission screw 95 is rotatably connected to the center of the handheld lever 1 and threadedly connected to the L-shaped block 93. A manual gear 96 is installed at the bottom end of the transmission screw 95 that rotates through the bottom of the handheld lever 1.

[0046] During operation, depending on the insulator suspension installation method, the manual gear 96 is driven to rotate, causing the transmission screw 95 inside the hand lever 1 to rotate. At this time, the L-shaped block 93 moves up and down along the direction of the transmission screw 95, thereby driving the tilting block 92 and the drive rotating block 91 to rotate. At this time, the fixed block 2 drives the semi-arc seat 1 3 and semi-arc seat 2 4 to rotate along the suspension direction of the insulator.

[0047] It is worth noting that when the fixed block 2 rotates, the brush disk 5 connected to it slides up and down along the L-shaped rod 714. The release force of the bending compression spring 717 keeps the drive gear and the rotating block 715 in contact, without affecting the intermittent movement of the arc seat 711.

[0048] It is worth noting that the limiting groove 90 provided in this invention allows the limiting rod to slide within the limiting groove 90, thereby not affecting the sliding of the fixing plate 713 within the arc-shaped seat 711.

[0049] Multiple ear seats 521 are welded to the side walls of the top semi-circular seat 3 and the top semi-circular seat 4. The multiple ear seats 521 are respectively arranged on the adjacent brush discs 5. A rotating rod 522 is rotatably connected to the inner side of the ear seat 521. A rotating component 523 that is rotatably connected to the brush disc 5 is installed in the middle of the rotating rod 522. A fixed plate 524 is installed at the end of the rotating rod 522 away from the ear seat 521. A return spring 525 sleeved on the outside of the rotating rod 522 is installed at the end of the fixed plate 524 away from the rotating component 523. A sleeve 526 sleeved on the rotating rod 522 is installed at the end of the return spring 525 facing away from the fixed plate 524. A compression ball 527 is installed at the end of the sleeve 526 facing away from the fixed plate 524.

[0050] During operation, when the surfaces of the insulators are surrounded by the semi-arc seat 3 and the semi-arc seat 4, the brushes of each group rotate tightly against the insulator. At this time, the rotating part 523 drives the rotating rod 522 to move synchronously, so that the pressing ball 527 is pressed against the insulator. Then, with the cooperation of the fixed plate 524, the return spring 525 and the sleeve 526, the insulators of different sizes can be kept in close contact with the pressing ball 527, so as to avoid damage to the outer wall of the insulator by the brush plate 5 during rotation.

[0051] In specific use: S1, firstly, according to the insulator suspension installation method, drive the manual gear 96 to rotate, so that the transmission screw 95 inside the hand handle 1 rotates. At this time, the L-shaped block 93 moves up and down along the direction of the transmission screw 95, which in turn drives the tilting block 92 and the drive rotating block 91 to rotate. At this time, the fixed block 2 drives the semi-arc seat 1 3 and semi-arc seat 2 4 to rotate along the suspension direction of the insulator.

[0052] S2. When it is necessary to adjust the spacing between the brush discs 5, the maintenance personnel pull the lever 813 upward with one hand. At this time, during the upward movement of the locking gear plate 814, the expansion spring 812 enters the compressed state, which causes the locking gear plate 814 to disengage from the gear teeth on the manual adjustment gear 81. The maintenance personnel rotate the manual torsion lever 83 with the other hand, which causes the manual adjustment gear 81 to drive the auxiliary adjustment gears 82 on both sides to rotate synchronously. With the cooperation of the auxiliary roller 85, the adjustment roller 84 and the connecting transmission belt 86, the auxiliary adjustment gear 82 drives the entire adjustment roller 84 to rotate until the spacing between each set of brush discs 5 is in contact with the insulator. Then, the lever 813 is released so that the locking gear plate 814 presses against the corresponding gear teeth of the manual adjustment gear 81 again.

[0053] S3. After the suspension direction of the semi-arc seat 1 3 and the semi-arc seat 2 4 and the distance between the brush disc 5 are adjusted, the maintenance personnel use the hand rod 1 to move the semi-arc seat 1 3 and the semi-arc seat 2 4 to one side of the insulator. The insulator is surrounded by the opening between the semi-arc seat 1 3 and the semi-arc seat 2 4. Then, the electric push rod 64 is driven to move up and down, so that the drive rod 62 rotates from the inside of the shaped frame 61. At this time, the drive rod 62 drives the drive frame 65 to open and rotate from the fixed block 2, so that the semi-arc seat 2 4 moves along the direction of the semi-arc seat 1 3. Finally, they are connected by magnetism. When it is necessary to open the semi-arc seat 2 4, the moving end of the electric push rod 64 drives the fixed ear 63 to retract. At the same time, the drive frame 65 and the drive rod 62 retract horizontally, which helps to improve the opening degree between the semi-arc seat 1 3 and the semi-arc seat 2 4.

[0054] S4. When the main motor inside the drive fixed block 2 is driven, it drives the drive gear 71 connected to it to rotate, thereby driving the auxiliary gears 72 on both sides to rotate synchronously. At this time, through the cooperation of the first conveyor belt 74 and the second auxiliary roller 75, the drive roller 73 on the entire semi-arc seat 3 and the second semi-arc seat 4 is driven to rotate. Through the rotation pressure of the first drive roller 73 and the cooperation of the second conveyor belt 77, the drive roller 76 inside the rotating block 50 is driven to rotate. Then, through the rotating shaft, the upper and lower brush disks 5 of the rotating block 50 are driven to rotate, so that each set of brushes can clean the insulator in all directions.

[0055] S5. During the rotation of the drive gear 71, it drives the connected rotating block 715 to rotate. At this time, the rotating block 715 drives the L-shaped rod 714 to slide along the arc-shaped seat 711. Then the slider 712 drives the bending rod 716 to move intermittently along the right side. At this time, the bending compression spring 717 enters the compressed state, and then the fixing plate 713 drives the fixing block 2 to rotate intermittently from the arc direction of the arc-shaped seat 711. This ensures that when the semi-arc seat 1 3 and the semi-arc seat 2 4 are fitted onto the large insulator, there is a lack of cleaning space between the brushes on the brush disk 5. Therefore, the L-shaped rod 714 drives the fixed plate 713 intermittently, which in turn drives the semi-arc seat 1 3 and semi-arc seat 2 4 to rotate in a limited position along the arc seat 711, thus solving the problem of the parts that need cleaning. When the rotating block 715 and the L-shaped rod 714 enter the disengaged state, the bending compression spring 717 releases elastic potential energy, causing the bending rod 716 to drive the slider 712 to return to its original position. At this time, the brush disk 5 returns to its original position to clean the edge of the insulator again. Through continuous intermittent movement, the cleaning effect is further improved.
