Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment maintenance, in particular to an AC / DC insulating porcelain sleeve electric cleaning device. Background Art

[0002] The insulating porcelain sleeves used in large quantities in converter stations will continue to accumulate dust, branches, bird droppings and other impurities during long-term outdoor exposure. The accumulation of these impurities will seriously reduce the insulation performance of the insulating porcelain sleeves and pose a direct threat to their insulation level. In order to deal with this problem, staff need to clean these insulating porcelain sleeves regularly to ensure their surface cleanliness and stable insulation performance. However, traditional cleaning methods can often only simply remove dust from the insulating porcelain sleeves, and cannot replenish water or deeply clean foreign matter.

[0003] More importantly, since the insulating porcelain sleeves are usually installed at a higher position, workers need to climb to clean them. This operation method not only limits the cleaning area, but also makes it impossible to comprehensively clean the surrounding same-level positions of the insulating porcelain sleeves, leaving cleaning dead corners and safety hazards. Moreover, if a complete 360-degree cleaning is required, the workers also need to adjust their positions at high altitudes, which will not only greatly increase the time cost of cleaning, but also further increase the high-altitude operation risks of maintenance personnel, posing a potential threat to their life safety. Therefore, there is an urgent need for a device that can comprehensively, efficiently and safely clean the insulating porcelain sleeves to solve this problem. Summary of the invention

[0006] Preferably, two groups of fixed blocks are fixedly installed on the top of the electric cleaning device body, and the number of fixed blocks in each group is two. A rotating rod three is rotatably installed on the side close to each other of the two groups of fixed blocks.

[0007] Preferably, two motors 2 are fixedly installed on the top of the sliding block, and rotating rods 2 are respectively fixedly installed on the output shafts of the two motors 2. The two rotating rods 2 both penetrate the sliding block and are rotatably connected to the sliding block, and three sets of cleaning wheels are respectively fixedly installed on the outer walls of the two sliding blocks.

[0008] Preferably, the diameter of each cleaning wheel presents a trend of gradually decreasing from the middle to both sides, that is, the diameter of the central part of each cleaning wheel reaches the maximum value, and then based on this, the diameter value gradually and smoothly decreases to both sides, forming an elegant conical or parabolic appearance.

[0009] Preferably, a water tank is fixedly installed inside the body of the electric cleaning device, and the bottom ends of the two bellows extend into the body of the electric cleaning device and are fixedly connected to the top of the water tank.

[0010] Preferably, a fixed mounting block is fixedly mounted on the inner wall of the bottom of the electric cleaning device body, and a rotating rod four is rotatably mounted on the outer wall of the fixed mounting block, and the rotating rod four passes through the fixed mounting block.

[0011] Preferably, a bevel gear 2 and a disc are fixedly sleeved on the outer wall of the rotating rod 4, and the bevel gear 2 is meshed with the bevel gear 1.

[0012] Preferably, a protrusion is fixedly mounted on one side of the disc, and the protrusion is located at a non-axial position of the disc.

[0013] Preferably, a tooth plate is slidably installed on the top of the electric cleaning device body, the bottom of the tooth plate extends into the electric cleaning device body, the tooth plate is meshed with the tooth column, and a grooved block is fixedly installed on the side of the tooth plate close to the protrusion, and the protrusion passes through the grooved block and is movably connected to the grooved block.

[0014] Preferably, a telescopic rod is rotatably mounted on the outer wall of the electric cleaning device body, and an insulating rod is fixedly mounted on the bottom of the telescopic rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention starts the motor 1, and its output shaft starts to rotate. The power is transmitted to the rotating rod 1, which then drives the rotating rod 1 to rotate synchronously. The rotation of the rotating rod 1 drives the tooth column 1 fixedly mounted on its outer wall to rotate. The tooth column 1 is tightly meshed with the tooth groove provided on the sliding block.

[0017] The present invention drives bevel gear one to rotate through rotating rod one, and drives bevel gear two and fixed mounting block to rotate through meshing of bevel gear one and bevel gear two, and the fixed mounting block drives the disk to rotate, and the disk drives the protrusion to rotate. Under the action of the grooved block, the circular motion of the protrusion is converted into reciprocating motion in the vertical direction of the tooth plate, and the tooth plate is meshed with the tooth column, thereby driving rotating rod three and rotating block to rotate together, and the rotating block drives the bellows and the nozzle to rotate. The rotation of the nozzle greatly expands the spraying range, so that the cleaning liquid or water can cover the surface of the insulating porcelain sleeve more evenly and comprehensively. This design not only improves the cleaning efficiency, but also ensures the uniformity and comprehensiveness of the cleaning, and provides a strong guarantee for the long-term stable operation of the insulating porcelain sleeve.

[0018] The present invention adopts a design in which the diameter of the cleaning wheel gradually decreases from the middle to the two sides, so that when it contacts the surface to be cleaned, it can form a more fitting contact surface, which not only improves the cleaning efficiency but also ensures the uniformity and thoroughness of cleaning. In particular, when dealing with complex surfaces or hard-to-reach corners, this design can exert a more significant cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, the present invention provides an AC / DC insulating porcelain sleeve electric cleaning device, comprising an electric cleaning device body 1, a sliding track 6 is fixedly installed on the outer wall of the electric cleaning device body 1, a sliding block 7 is slidably installed on the inner wall of the sliding track 6, a tooth groove 701 is provided on the side of the sliding block 7 close to the inner wall of the sliding track 6, a motor 2 is fixedly installed on the electric cleaning device body 1, a rotating rod 3 is fixedly installed on the output shaft of the motor 2, the bottom end of the rotating rod 3 extends into the electric cleaning device body 1 and is rotatably connected to the bottom inner wall of the electric cleaning device body 1, a tooth column 4 and a bevel gear 5 are fixedly sleeved on the outer wall of the rotating rod 3, the tooth column 4 is located above the bevel gear 5, and the tooth column 4 is meshed with the tooth groove 701.

[0030] By starting the motor 2, its output shaft starts to rotate, and this power is transmitted to the rotating rod 3, which in turn drives the rotating rod 3 to rotate synchronously. The rotation of the rotating rod 3 drives the tooth column 4 fixed on its outer wall to rotate, and the tooth column 4 is tightly meshed with the tooth groove 701 provided on the sliding block 7. This design ensures that when the tooth column 4 rotates, it can accurately drive the sliding block 7 to rotate smoothly and orderly in the sliding track 6. As the sliding block 7 rotates, the cleaning wheel 10 installed thereon also changes its position and angle, thereby realizing multi-angle cleaning of the insulating porcelain sleeve. This multi-angle cleaning method not only improves the cleaning efficiency, but also ensures the comprehensiveness and uniformity of cleaning, and effectively avoids the problem of cleaning dead angles caused by limited cleaning angles in traditional devices.

[0031] like Figures 1 to 8 As shown, two groups of fixed blocks 11 are fixedly installed on the top of the electric cleaning device body 1, and the number of fixed blocks 11 in each group is two. A rotating rod three 1101 is rotatably installed on the side close to each other of the two groups of fixed blocks 11. A tooth column 12 and two rotating blocks 13 are fixedly sleeved on the outer wall of the rotating rod three 1101. Bellows 15 are fixedly installed inside the two rotating blocks 13 respectively, and nozzles 1501 are fixedly installed on the side of the two bellows 15 close to the sliding track 6 respectively.

[0032] The bevel gear 15 is driven to rotate by the rotating rod 13, and the meshing of the bevel gear 15 and the bevel gear 2 17 drives the bevel gear 2 17 and the fixed mounting block 16 to rotate, and the fixed mounting block 16 drives the disk 18 to rotate, and the disk 18 drives the protrusion 19 to rotate. Under the action of the grooved block 20, the circular motion of the protrusion 19 is converted into reciprocating motion in the vertical direction of the tooth plate 21, and the tooth plate 21 is meshed with the tooth column 12, thereby driving the rotating rod 3 1101 and the rotating block 13 to rotate together, and the rotating block 13 drives the bellows 15 and the nozzle 1501 to rotate. The rotation of the nozzle 1501 greatly expands the spraying range, so that the cleaning liquid or water can cover the surface of the insulating porcelain sleeve more evenly and comprehensively. This design not only improves the cleaning efficiency, but also ensures the uniformity and comprehensiveness of the cleaning, and provides a strong guarantee for the long-term stable operation of the insulating porcelain sleeve.

[0033] like Figures 1 to 8 As shown, two motors 28 are fixedly installed on the top of the sliding block 7, and rotating rods 29 are respectively fixedly installed on the output shafts of the two motors 28. The two rotating rods 29 both penetrate the sliding block 7 and are rotatably connected to the sliding block 7. Three sets of cleaning wheels 10 are respectively fixedly installed on the outer walls of the two sliding blocks 7.

[0034] The motor 2 8 drives the rotating rod 2 9 to rotate, which in turn drives the cleaning wheel 10 to rotate at high speed. The device can achieve efficient cleaning of the target surface. The setting of three sets of cleaning wheels 10 not only increases the cleaning coverage, but also improves the cleaning efficiency and uniformity. This design enables the device to easily cope with various stains and difficult-to-clean areas, ensuring the thoroughness and consistency of the cleaning effect.

[0035] like Figures 1 to 8 As shown, the diameter of each cleaning wheel 10 shows a trend of gradually decreasing from the middle to both sides, that is, the diameter of the central part of each cleaning wheel 10 reaches the maximum value, and then based on this, the diameter value gradually and smoothly decreases to both sides, forming an elegant conical or parabolic appearance.

[0036] The design of the cleaning wheel 10 gradually reducing its diameter from the middle to both sides allows it to form a more fitting contact surface when in contact with the surface to be cleaned, which not only improves the cleaning efficiency but also ensures the uniformity and thoroughness of cleaning. This design can produce a more significant cleaning effect, especially when dealing with complex surfaces or hard-to-reach corners.

[0037] like Figures 1 to 8 As shown, a water tank 14 is fixedly installed inside the electric cleaning device body 1 , and the bottom ends of the two bellows 15 extend into the electric cleaning device body 1 and are fixedly connected to the top of the water tank 14 .

[0038] The sprayed cleaning liquid can soften, decompose or emulsify stains, making the physical cleaning of the cleaning wheel 10 more efficient. At the same time, the wetting effect of the liquid can also reduce the dust and particulate matter generated during the cleaning process, keeping the cleaning environment tidy and sanitary. The design of the water tank 14 allows the cleaning liquid to be stored in a centralized manner and used on demand, avoiding the waste of water resources in traditional cleaning methods. By precisely controlling the spraying amount of the bellows 15, it can be ensured that every drop of cleaning liquid is used to the maximum extent, achieving the goal of water saving and environmental protection.

[0039] like Figures 1 to 8 As shown, a fixed mounting block 16 is fixedly mounted on the inner wall of the bottom of the electric cleaning device body 1, and a rotating rod 4 1601 is rotatably mounted on the outer wall of the fixed mounting block 16, and the rotating rod 4 1601 passes through the fixed mounting block 16.

[0040] By fixing the fixed mounting block 16 on the inner wall at the bottom of the electric cleaning device body 1 and rotatably mounting the rotating rod four 1601 thereon, the device achieves a compact structural design, reduces the size of the device, and improves its overall stability, making the device more stable and reliable during operation. The rotating rod four 1601 can penetrate the fixed mounting block 16 and achieve free rotational movement, so that the device can adjust the rotation angle and speed of the rotating rod four 1601 as needed to meet different needs.

[0041] like Figures 1 to 8 As shown, a bevel gear 2 17 and a disc 18 are fixedly sleeved on the outer wall of the rotating rod 4 1601, and the bevel gear 2 17 is meshed with the bevel gear 1 5.

[0042] The bevel gear 2 17 is driven to rotate by the rotating rod 4 1601, and the bevel gear 2 17 is meshed with the bevel gear 1 5, thereby realizing the transmission and conversion of power.

[0043] like Figures 1 to 8 As shown, a protrusion 19 is fixedly mounted on one side of the disk 18 , and the protrusion 19 is located at a non-axial position of the disk 18 .

[0044] The design of the protrusion 19 being offset to one side of the disc 18 allows the disc to generate a more complex motion trajectory when rotating, thereby providing transmission support for the toothed plate 21 in the vertical direction.

[0045] like Figures 1 to 8 As shown, a tooth plate 21 is slidably installed on the top of the electric cleaning device body 1, and the bottom of the tooth plate 21 extends into the electric cleaning device body 1. The tooth plate 21 is meshed with the tooth column 12. A grooved block 20 is fixedly installed on one side of the tooth plate 21 close to the protrusion 19. The protrusion 19 penetrates the grooved block 20 and is movably connected to the grooved block 20.

[0046] Through the tight engagement of the tooth plate 21 and the tooth column 12, the device realizes precise control of the rotation of the tooth column 12. The movable connection design between the groove block 20 and the protrusion 19 enables the protrusion 19 to move in the groove block 20 when performing circular rotational motion, thereby driving the tooth plate 21 to perform reciprocating motion in the vertical direction.

[0047] like Figures 1 to 8 As shown, a telescopic rod 22 is rotatably mounted on the outer wall of the electric cleaning device body 1, and an insulating rod 23 is fixedly mounted on the bottom of the telescopic rod 22.

[0048] By adjusting the length of the telescopic rod 22, the operator can easily adjust the working range of the cleaning device according to actual needs, thereby improving work efficiency. The use of the insulating rod 23 provides additional safety protection for the operator, ensuring personal safety even when working in a high-voltage environment, which meets the high standards of the power industry for safe operations.

[0049] The working principle and use process of the present invention:

[0050] First, start the motor 2. Both the motor 2 and the motor 2 8 are high rated speed motors. The output shaft of the motor 2 starts to rotate, and the power is transmitted to the rotating rod 3, driving it to rotate synchronously. The rotation of the rotating rod 3 drives the tooth column 4 fixed on its outer wall to rotate. The tooth column 4 is tightly meshed with the tooth groove 701 provided on the sliding block 7, driving the sliding block 7 to rotate smoothly and orderly in the sliding track 6. The sliding block 7 drives the cleaning wheel 10 to clean at multiple angles: then start the rotation of the motor 2 8. The output shaft of the motor 2 8 drives the rotating rod 2 9 to rotate. The rotating rod 2 9 drives the cleaning wheel 10 to rotate at high speed to achieve the target surface. At the same time, the rotating rod 3 also drives the bevel gear 5 to rotate. The bevel gear 5 is meshed with the bevel gear 2 17, and the power is transmitted to the bevel gear 2 17. The disc 18 and the protrusion 19 drive the tooth plate 21 to reciprocate: the bevel gear 2 17 drives the disc 18 to rotate, and the protrusion 1 on the disc 18 drives the tooth plate 21 to reciprocate. Under the action of the grooved block 20, the circular motion is converted into reciprocating motion in the vertical direction of the tooth plate 21. The tooth plate 21 is meshed with the tooth column 12, driving the rotating rod 3 1101 and the rotating block 13 to rotate together. The rotating block 13 drives the bellows 15 and the nozzle 1501 to rotate: the rotation of the rotating block 13 drives the bellows 15 and the nozzle 1501 to rotate. The rotation of the nozzle 1501 greatly expands the spraying range, so that the cleaning liquid or water can cover the surface of the insulating porcelain sleeve more evenly and comprehensively. The bottom end of the bellows 15 is fixedly connected to the top of the water tank 14 to provide cleaning liquid. The cleaning liquid is sprayed onto the surface of the insulating porcelain sleeve through the nozzle 1501 to soften, decompose or emulsify the stains. The operator can adjust the length of the telescopic rod 22 according to actual needs to adjust the working range of the cleaning device. The insulating rod 23 provides additional safety protection for the operator to ensure personal safety when working in a high-pressure environment.
