Description

Technical Field

[0001] This invention belongs to the field of substation equipment maintenance technology, and more specifically, relates to a dust cleaning device for substation equipment. Background Technology

[0002] Transformer equipment is used for power transmission, transformation, and distribution. It mainly includes transformers, circuit breakers, disconnect switches, capacitors, and reactors. They play a very important role in the power system, used to realize the transmission, transformation, distribution, and protection of electrical energy. The importance of cleaning transformer equipment is mainly reflected in the following aspects: it prevents the accumulation of dust, debris, and other contaminants on the equipment from affecting its heat dissipation and insulation performance. Regular cleaning can also help detect cracks, corrosion, and other problems on the equipment surface, allowing for timely maintenance and repair, and ensuring the safe operation of the equipment. Therefore, regular cleaning is essential to ensure the normal operation, safety, and service life of transformer equipment.

[0003] 1. Existing equipment can only clean one side of the equipment when cleaning it, and cannot clean multiple sides of the equipment simultaneously. This results in low cleaning efficiency, high labor intensity for workers, and its practicality needs to be improved.

[0004] 2. When cleaning power equipment, the existing equipment usually uses a threaded connection to connect the felt roller to the cleaning equipment. Although it is secure, the felt roller needs to be disassembled one by one when it is maintained, which is inconvenient.

[0005] 3. Existing devices often only have the ability to clean power equipment and perform cleaning with a certain adjustable range. They cannot simultaneously complete multi-faceted cleaning and adjustment of power equipment, resulting in limited functionality and a need to improve practicality.

[0006] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a dust cleaning device for power equipment, in order to achieve a more practical purpose. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a dust cleaning device for power equipment, thereby resolving the problems described above.

[0008] A dust cleaning device for power equipment includes a trolley, a power supply module is provided at the upper end of the trolley, and lead screw motors are symmetrically fixedly installed at the lower end of the trolley. The output shafts of the two lead screw motors are partially exposed above the trolley, and the output shafts of the two lead screw motors are rotatably mounted to the trolley. A base is threaded between the output shafts of the two lead screw motors.

[0009] Both of the bases are fixedly equipped with embedded three-sided adjustment mechanisms at their upper ends;

[0010] The embedded three-sided adjustment mechanism includes a fixed base, two motors fixedly mounted on the side walls of the two fixed bases, a bidirectional lead screw rotatably mounted between the two fixed bases, the bidirectional lead screw being fixedly mounted to the output shaft of the motor, and the output shaft of the motor being rotatably mounted to the fixed base. The embedded three-sided adjustment mechanism also includes a slide groove, a through groove, a U-shaped threaded block, a first slider, a placement plate, a second slider, a straight groove, a clamping element, a first rotating groove, an electric push rod, a second rotating groove, a slide bar, a limiting plate, and a groove element.

[0011] Preferably, both of the sliding grooves are formed through the inside of the fixed seat, the through groove is formed through the inside of the base, both of the U-shaped threaded blocks are located on the circumferential surface of the bidirectional lead screw, both of the U-shaped threaded blocks are threadedly installed with the bidirectional lead screw, both of the first sliders are located between the U-shaped threaded blocks, both of the first sliders are fixedly installed with the U-shaped threaded blocks, both of the first sliders are located inside the through groove, and both of the first sliders are slidably installed with the through groove.

[0012] Preferably, both of the placement plates are located at the upper end of the U-shaped threaded block, and both of the placement plates are fixedly installed with the U-shaped threaded block. Both of the second sliders are located at the lower end of the placement plates, and both of the second sliders are fixedly installed with the placement plates. Both of the second sliders are located inside the slide groove, and both of the second sliders are slidably installed with the slide groove. Both of the straight grooves are opened through the interior of the placement plates. Both of the clamping members are located at the upper end of the placement plates, and both of the clamping members are fixedly installed with the placement plates. Both of the first rotating grooves are opened on the side wall of the clamping members. A first felt roller is slidably installed between the two first rotating grooves. Both of the electric push rods are located at the upper end of the second sliders, and both of the electric push rods are fixedly installed with the second sliders. Both of the electric push rods are located outside the clamping members.

[0013] Preferably, each of the two electric push rods has a fixing strip and a piston on its surface, both second rotating grooves are opened inside the fixing strips, both slide bars are located inside the straight grooves and are slidably installed with the straight grooves, both limiting plates are located on the surface of the slide bars and are fixedly installed with the slide bars and are adapted to the pistons, both grooved parts are located at the upper end of the slide bars and are fixedly installed with the slide bars, and a second felt roller is slidably installed between the two second rotating grooves and the grooved parts.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, by setting an embedded three-sided adjustment mechanism, after the motor is turned on, the output shaft of the motor will drive the bidirectional lead screw to rotate between the fixed seats and generate thread transmission with the U-shaped threaded blocks. At this time, the two U-shaped threaded blocks will drive the placement plates to move away from each other, thereby controlling the distance between the two clamping parts, so as to be able to use transformer boxes of different widths and improve applicability.

[0016] In this invention, by clamping the electric push rod to the outside of the clamping member, when the clamping member is adjusted according to the width of the transformer box, the second felt roller on the electric push rod can also contact both sides of the transformer box. Thus, the transformer box can be adjusted on three sides and cleaned when the clamping member is adjusted, improving its practicality.

[0017] In this invention, by turning on and resetting the motor, the motor can drive the bidirectional lead screw to rotate and generate threaded transmission with the U-shaped threaded block, thereby controlling the clamping parts to move away from each other and closer to each other. This allows the two clamping parts to clamp the first felt roller. Furthermore, by turning on and resetting the electric push rod, the limiting plate can generate a radial force, causing the limiting plate to move the slide bar and the groove towards the power supply module side. This reduces the distance between the groove and the second rotating groove, allowing the second felt roller to be inserted into the second rotating groove and the groove. This facilitates the installation and removal of the first and second felt rollers and makes maintenance easier.

[0018] In this invention, by pulling the slide bar towards the groove, the slide bar slides in the straight groove. The spacing between the fixing bar and the groove can be adjusted according to the thickness of the transformer box. Furthermore, the piston on the electric push rod generates a radial force on the limiting plate, which moves the limiting plate, the slide bar, and the groove towards the power supply module. This allows the second felt roller to be inserted between the second rotating groove and the groove, thus fixing second felt rollers of different thicknesses and improving applicability.

[0019] In this invention, by setting a sliding groove and a second slider, when the U-shaped threaded block and the bidirectional lead screw undergo threaded transmission, the second slider on the placement plate will slide in the sliding groove, thereby providing a certain limit and support, and improving stability.

[0020] In this invention, by optimizing the structure and layout of the device and setting an embedded three-sided adjustment mechanism, the mutual cooperation between the sliding groove, through groove, straight groove, U-shaped threaded block, first slider, second slider, fixing bar, and sliding bar allows the device as a whole to utilize its internal space when extending and retracting the length and width of the first felt roller and the second felt roller according to the width and thickness of the transformer box. This allows the device to maintain a compact structure even with multiple functions, improving its storage capacity. Attached Figure Description

[0031] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] Please see Figures 1-9The present invention provides a dust cleaning device for power equipment, including a trolley 11, a power supply module 12 at the upper end of the trolley 11, and lead screw motors 13 symmetrically fixedly installed at the lower end of the trolley 11. The output shafts of the two lead screw motors 13 are partially exposed above the trolley 11, and the output shafts of the two lead screw motors 13 are rotatably mounted with the trolley 11. A base 14 is threaded between the output shafts of the two lead screw motors 13.

[0033] Both bases 14 have embedded three-sided adjustment mechanisms fixedly installed on their upper ends;

[0034] The embedded three-sided adjustment mechanism includes a fixed base 15, with a motor 16 fixedly mounted on the side wall of two fixed bases 15. A bidirectional lead screw 17 is rotatably mounted between the two fixed bases 15. The bidirectional lead screw 17 is fixedly mounted to the output shaft of the motor 16, and the output shaft of the motor 16 is rotatably mounted to the fixed base 15. The embedded three-sided adjustment mechanism also includes a slide groove 18, a through groove 19, a U-shaped threaded block 21, a first slider 22, a shelf 23, a second slider 24, a straight groove 25, a clamping element 26, a first rotating groove 27, an electric push rod 29, a second rotating groove 33, a slide bar 34, and a limiting plate 35. With the groove 36, by optimizing the structure and layout of the device and setting an embedded three-sided adjustment mechanism, the mutual cooperation between the slide 18, through groove 19, straight groove 25, U-shaped threaded block 21, first slider 22, second slider 24, fixing strip 31 and slide bar 34 allows the device to utilize its internal space when extending and retracting the length and width of the first felt roller 28 and the second felt roller 37 according to the width and thickness of the transformer box. This allows the device to maintain a compact structure even with multiple functions, improving its storage capacity.

[0035] Both slide grooves 18 are formed through the inside of the fixed base 15, and the through groove 19 is formed through the inside of the base 14. Both U-shaped threaded blocks 21 are located on the circumferential surface of the bidirectional lead screw 17 and are threadedly installed with the bidirectional lead screw 17. Both first sliders 22 are located between the U-shaped threaded blocks 21 and are fixedly installed with the U-shaped threaded blocks 21. Both first sliders 22 are located inside the through groove 19 and are slidably installed with the through groove 19. By setting the slide grooves 18 and the second sliders 24, when the U-shaped threaded blocks 21 and the bidirectional lead screw 17 are threadedly driven, the second sliders 24 on the shelf 23 will slide in the slide grooves 18, thereby providing a certain limit and support and improving stability.

[0036] Both storage plates 23 are located at the upper end of the U-shaped threaded block 21, and both storage plates 23 are fixedly installed with the U-shaped threaded block 21. Both second sliders 24 are located at the lower end of the storage plates 23, and both second sliders 24 are fixedly installed with the storage plates 23. Both second sliders 24 are located inside the slide groove 18, and both second sliders 24 are slidably installed with the slide groove 18. Both straight grooves 25 are opened through the inside of the storage plates 23. Both clamping members 26 are located at the upper end of the storage plates 23, and both clamping members 26 are fixedly installed with the storage plates 23. Both first rotating grooves 27 are opened on the side wall of the clamping members 26, and a first felt roller 28 is slidably installed between the two first rotating grooves 27. Both electric push rods 29 are located at the upper end of the second sliders 24, and both electric push rods 29 are fixedly installed with the second sliders 24. With fixed installation, both electric push rods 29 are located outside the clamping member 26. By setting an embedded three-sided adjustment mechanism, after the motor 16 is turned on, the output shaft of the motor 16 will drive the bidirectional lead screw 17 to rotate between the fixed base 15 and generate threaded transmission with the U-shaped threaded block 21. At this time, the two U-shaped threaded blocks 21 will drive the placement plate 23 to move away from each other, thereby controlling the distance between the two clamping members 26. This allows for the use of transformer boxes of different widths, improving applicability. By clamping the electric push rod 29 to the outside of the clamping member 26, when the clamping member 26 is adjusted according to the width of the transformer box, the second felt roller 37 on the electric push rod 29 can also contact both sides of the transformer box. This allows for three-sided adjustment of the transformer box when adjusting the clamping member 26, improving practicality.

[0037] Each of the two electric push rods 29 has a fixing strip 31 and a piston 32 on its surface. Two second rotating grooves 33 are formed inside the fixing strips 31. Two sliding bars 34 are located inside the straight grooves 25 and are slidably installed with the straight grooves 25. Two limiting plates 35 are located on the surface of the sliding bars 34 and are fixedly installed with the sliding bars 34. Both limiting plates 35 are adapted to the pistons 32. Two recessed pieces 36 are located at the upper end of the sliding bars 34 and are fixedly installed with the sliding bars 34. The two second rotating grooves 33 and the recessed pieces 36 slide against each other. The second felt roller 37 is installed. By pulling the slide bar 34 towards the groove 36, the slide bar 34 slides in the straight groove 25. The spacing between the fixing bar 31 and the groove 36 can be adjusted according to the thickness of the transformer box. Furthermore, the piston 32 on the electric push rod 29 causes the limiting plate 35 to generate a radial force, which drives the limiting plate 35 to move the slide bar 34 and the groove 36 towards the power supply module 12. The second felt roller 37 can be inserted between the second rotating groove 33 and the groove 36. Therefore, second felt rollers 37 of different thicknesses can be fixed, improving applicability.

[0038] Working principle:

[0039] The first step is to adjust the spacing of the clamping parts 26 according to the size of the transformer box and install the first felt roller 28 so that the first felt roller 28 can make more comprehensive contact with the surface of the transformer box for cleaning.

[0040] When it is necessary to adjust the spacing of the clamping members 26 and install the first felt roller 28, the motor 16 can be turned on first. The motor 16's output shaft rotates, driving the bidirectional lead screw 17 to rotate between the fixed seats 15 and engage in threaded transmission with the U-shaped threaded blocks 21. At this time, the two U-shaped threaded blocks 21 will drive the placement plates 23 away from each other, and the movement of the U-shaped threaded blocks 21 will cause the two clamping members 26 to move away from each other. Simultaneously, the second slider 24 on the placement plate 23 will slide within the slide groove 18. When the spacing between the two clamping members 26 is greater than the width of the transformer box, the first felt roller 28, which is compatible with the size of the transformer box, can be taken and placed between the first rotating grooves 27 on the clamping members 26. At this time, the motor 16 can be reversed, causing the two U-shaped threaded blocks 21 to drive the clamping members 26 closer together until the rotating shafts on both sides of the first felt roller 28 are located within the first rotating grooves 27 on the clamping members 26. At this point, the adjustment of the clamping member spacing and the installation of the first felt roller 28 have been completed.

[0041] The second step is to install the second felt roller 37 between the second rotating groove 33 and the groove 36, and adjust the extension distance of the second felt roller 37 according to the thickness of the transformer box so that the second felt roller 37 fully contacts both sides of the transformer box.

[0042] When it is necessary to install the second felt roller 37 and adjust the extension distance of the second felt roller 37, firstly, a second felt roller 37 with a thickness greater than that of the transformer box can be prepared. Then, the slide bar 34 can be pulled towards the groove 36, so that the slide bar 34 slides in the straight groove 25 until the distance between the fixing bar 31 and the groove 36 is greater than the thickness of the transformer box. Then, one side of the rotating shaft of the second felt roller 37 can be placed in the second rotating groove 33. At this time, the piston 32 on the electric push rod 29 can be opened, so that the piston 32 pushes the limiting plate 35 to move towards the power supply module 12. At this time, the limiting plate 35 will generate a radial force, so that the limiting plate 35 drives the slide bar 34 and the groove 36 towards the power supply module 12. As the power supply module 12 moves to one side, the distance between the groove 36 and the second rotating groove 33 decreases. The shaft of the second felt roller 37 on the side away from the second rotating groove 33 can then be inserted into the groove 36. The above steps can then be repeated to install the remaining second felt rollers 37. After installation, the trolley 11 can be pushed to the rear of the power supply module 12 until the felt of the first felt roller 28 contacts the surface of the transformer box. When the felt of the first felt roller 28 contacts the surface of the transformer box, since the clamping member 26 is adjusted according to the width of the transformer box and the electric push rod 29 is located outside the clamping member 26, the second felt roller 37 on the electric push rod 29 can also contact both sides of the transformer box.

[0043] The third step is to clean the transformer box and disassemble the first felt roller 28 and the second felt roller 37.

[0044] When cleaning the transformer box is required, first turn on the lead screw motor 13, so that the two lead screw motors 13 rotate synchronously and engage with the base 14 through a threaded drive. This causes the base 14 to rise on the output shaft of the lead screw motor 13, which in turn causes the first felt roller 28 and the second felt roller 37 to rise together, thus completing the cleaning of the transformer box. After cleaning the transformer box is completed, the lead screw motor 13 can be reset and the motor 16 can be turned on again, so that the motor 16 drives the bidirectional lead screw 17 to rotate and engage with the U-shaped threaded block 21 through a threaded drive. This causes the two U-shaped threaded blocks to engage with the U-shaped threaded block 21 through a threaded drive. The textured block 21 moves the placement plate 23 away from each other, thereby causing the clamping parts 26 to move away from each other, and thus causing the shaft of the first felt roller 28 to disengage from the first rotating groove 27. At this time, the disassembly of the first rotating groove 27 can be completed. When it is necessary to disassemble the second felt roller 37, the piston 32 can be reset, and then the slide bar 34 can be pulled away from the piston 32, so that the slide bar 34 moves again in the straight groove 25, thereby causing the groove part 36 to disengage from the shaft on one side of the second felt roller 37. At this time, the second felt roller 37 can be directly removed, thus completing the disassembly of the second felt roller 37.
