Description

Technical Field

[0001] This invention relates to the technical field of insulator cleaning devices, and more specifically to a device for supporting insulator cleaning. Background Technology

[0002] Support insulators are critical components in power systems used to support conductors and ensure electrical insulation. They are typically installed in transmission lines or substations. Their function is to isolate live conductors from grounding structures through their high insulation performance, preventing current leakage or short circuits and ensuring the safe and stable operation of the power grid. Due to long-term exposure to the outdoor environment, support insulators are prone to accumulating dust, salt, bird droppings, industrial pollutants, and other contaminants on their surface. These contaminants can form a conductive layer under humid conditions, significantly reducing insulation performance and potentially causing flashovers or even breakdowns, leading to power outages or equipment damage. Therefore, it is necessary to clean support insulators regularly to restore their insulation strength, avoid safety hazards caused by contaminant accumulation, extend equipment lifespan, and ensure the efficient and reliable operation of the power system.

[0003] In related technologies, cleaning of supporting insulators relies on manual operation, which has low cleaning efficiency, and the operators need to work in a high-altitude and high-voltage environment, which poses a significant safety risk. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a support insulator cleaning device that can achieve automatic cleaning of support insulators with high cleaning efficiency and high safety.

[0006] The insulator cleaning device of this invention includes a walking device, a base, a robotic arm, a cleaning device, and a liquid supply device. The base is connected to the walking device. The robotic arm has a mounting end and a movable end that are relatively movable, and the mounting end is connected to the base. The cleaning device includes a connecting frame, a first arc plate, and a second arc plate. The connecting frame is connected to the movable end. The connecting frame has a liquid-containing cavity and multiple high-pressure flushing ports communicating with the liquid-containing cavity. The first arc plate and the second arc plate are rotatably connected to the connecting frame, so that the cleaning device can switch between a closed mode and an open mode. The liquid supply device is used to provide cleaning solution to the liquid-containing cavity. When the cleaning device is in the closed mode, the first arc plate, the second arc plate, and the connecting frame form a cylindrical cavity for placing the insulator, and the high-pressure flushing ports are arranged facing the cylindrical cavity. When the cleaning device is in the open mode, an inlet and outlet channel for the insulator to pass through is formed between the first arc plate and the second arc plate.

[0007] In some embodiments, the cleaning equipment further includes a recycling device, which includes a bottom sealing assembly and a wastewater filter. The bottom sealing assembly includes a first half-cover and a second half-cover. The upper end of the first half-cover is connected to the first arc plate, and the upper end of the second half-cover is connected to the second arc plate. The lower ends of both the first and second half-covers are movably connected to the connecting frame, so that the bottom sealing assembly can switch between an unfolded mode and a retracted mode. When the cleaning device is in a closed mode and the bottom sealing assembly is in a retracted mode, the cylinder cavity has a downwardly arranged lower opening. The first and second half-covers can tightly fit against the outer wall of the supporting insulator to block the lower opening of the cylinder cavity. The wastewater filter is connected to the base and has a recycling chamber. The first arc plate and / or the second arc plate have a through-flow return port, and the recycling chamber communicates with the return port.

[0008] In some embodiments, the first arc plate has a sealing protrusion on the side facing the second arc plate, and the second arc plate has a sealing groove on the side facing the first arc plate. When the cleaning device is in closed mode, the sealing protrusion is inserted into the sealing groove.

[0009] In some embodiments, the wastewater filter further includes a water purification chamber, which is in communication with the liquid storage chamber.

[0010] In some embodiments, the first half-cover includes a first cover fabric and a first rib, the upper end of the first cover fabric being connected to the first arc plate, the lower end of the first cover fabric being connected to the first rib, and the first rib including a plurality of first electromagnets spaced apart along the lower edge of the first cover fabric; the second half-cover includes a second cover fabric and a second rib, the upper end of the second cover fabric being connected to the second arc plate, the lower end of the second cover fabric being connected to the second rib, and the second rib including a plurality of second electromagnets spaced apart along the lower edge of the second cover fabric; wherein, when the plurality of first electromagnets and the plurality of second electromagnets are energized, they can attract each other sequentially to retract the lower ends of the first half-cover and the second half-cover, thereby switching the bottom sealing assembly to the retracted mode.

[0011] In some embodiments, the first and second ribs are each connected to a rubber sheet on the side of the ribs that are close to each other, for fitting against the outer wall of the supporting insulator.

[0012] In some embodiments, the dimensions of both the first and second ribs along the length of the cylinder are less than 1 cm.

[0013] In some embodiments, the liquid supply device includes a pump body and a first solution tank, a second solution tank, and a third solution tank for holding cleaning solutions of different components, respectively. The outlet of the pump body is connected to the liquid-containing chamber, and the first solution tank, the second solution tank, and the third solution tank are all connected to the inlet of the pump body.

[0014] In some embodiments, the robotic arm includes a first arm segment, a second arm segment, and a third arm segment that are movably connected in sequence. The first arm segment is movably connected to the base, and the cleaning device is connected to the third arm segment.

[0015] In some embodiments, the walking device includes a track mechanism and a walking frame, and a plurality of spring buffers are provided between the base and the walking frame.

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 4 As shown, the insulator cleaning device 100 of this embodiment includes a walking device 1, a base 2, a robotic arm 3, a cleaning device 4, and a liquid supply device 5. The base 2 is connected to the walking device 1, and the robotic arm 3 has a mounting end and a movable end that are relatively movable. The mounting end is connected to the base 2. The cleaning device 4 includes a connecting frame 41, a first arc plate 42, and a second arc plate 43. The connecting frame 41 is connected to the movable end and has a liquid-containing cavity and a plurality of high-pressure flushing ports 4111 communicating with the liquid-containing cavity. The first arc plate 42 and the second arc plate 43 are rotatably connected to the connecting frame 41 so that the cleaning device 4 can switch between a closed mode and an open mode. The liquid supply device 5 is used to provide cleaning solution to the liquid-containing cavity. When the cleaning device 4 is in the closed mode, the first arc plate 42, the second arc plate 43, and the connecting frame 41 form a cylindrical cavity 44 for placing the insulator. The high-pressure flushing ports 4111 are arranged facing the cylindrical cavity 44. When the cleaning device 4 is in the open mode, an inlet and outlet channel for the insulator to pass through is formed between the first arc plate 42 and the second arc plate 43.

[0032] The insulator cleaning device 100 of this invention, when cleaning the insulator, first uses a walking device 1 to move to the base of a high-voltage tower in the field. Then, a robotic arm 3 moves a cleaning device 4 to the side of the insulator. The cleaning device 4 is switched to an open mode, and the robotic arm 3 moves it closer to the insulator, allowing the insulator to be cleaned to enter between the first arc plate 42 and the second arc plate 43 through the inlet / outlet channel. The cleaning device 4 is then switched to a closed mode, with the first arc plate 42, the second arc plate 43, and the connecting frame 41 forming a cylindrical cavity 44, within which the insulator is located. Next, a cleaning solution supply device supplies cleaning solution to the liquid-containing cavity. The cleaning solution is sprayed out through multiple high-pressure flushing ports 4111 and impacts the outer wall of the insulator, thus cleaning the insulator. Furthermore, the operator can use the walking device 1 and the robotic arm 3 to adjust the relative position of the cleaning device 4 and the insulator, allowing the high-pressure flushing ports 4111 to perform high-pressure flushing at different locations on the outer wall of the insulator along its circumference, achieving comprehensive cleaning of the insulator.

[0033] The support insulator cleaning device 100 of this invention can automatically clean the support insulators with high cleaning efficiency, and does not require operators to work in a high-altitude and high-pressure environment, thus ensuring high operational safety.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, the connecting frame 41 includes a cleaning plate 411 and a connecting seat 412. The cleaning plate 411 and the connecting seat 412 are fixedly connected. The connecting seat 412 is detachably connected to the movable end of the robotic arm 3 by bolts. This allows for a detachable connection between the cleaning device 4 and the robotic arm 3, facilitating the inspection and maintenance of the cleaning device 4.

[0035] The cleaning plate 411 has a hollow structure to form the aforementioned liquid-containing cavity inside. Multiple high-pressure flushing ports 4111 are arranged on the side wall of the cleaning plate 411 near the middle area between the first arc plate 42 and the second arc plate 43. The multiple high-pressure flushing ports 4111 are evenly distributed on this side wall of the cleaning plate 411. Rotating columns 45 are rotatably connected to both sides of the cleaning plate 411. The first arc plate 42 and the second arc plate 43 are both arc plates. The first arc plate 42 and the second arc plate 43 are both fixedly connected to the rotating columns 45. The rotating columns 45 are driven by motors. Each rotating column 45 is equipped with a corresponding motor. The two motors can drive the first arc plate 42 and the second arc plate 43 to rotate, so that the cleaning device 4 can switch between closed mode and open mode.

[0036] When the cleaning device 4 is in the open mode, the first arc plate 42 and the second arc plate 43 have a gap on the side away from the cleaning plate 411 to form an inlet and outlet channel. Moving the cleaning device 4 toward the support insulator allows the support insulator to enter between the first arc plate 42 and the second arc plate 43 through the inlet and outlet channel for cleaning. Similarly, after cleaning is completed, moving the cleaning device 4 away from the support insulator allows the support insulator to detach from the cleaning device 4.

[0037] After the supporting insulator enters between the first arc plate 42 and the second arc plate 43, the control cleaning device 4 switches to the closed mode. The first arc plate 42 and the second arc plate 43 are relatively close to each other and their sides away from the cleaning plate 411 abut against each other. The cleaning plate 411, the first arc plate 42 and the second arc plate 43 form a cylindrical cavity 44. The liquid supply device 5 provides cleaning solution to the liquid cavity. The cleaning solution is sprayed out through multiple high-pressure flushing ports 4111 on the cleaning plate 411 and impacts the outer wall of the supporting insulator, thereby achieving the cleaning of the supporting insulator.

[0038] In some embodiments, such as Figures 2 to 4 As shown, the cleaning equipment also includes a recycling device 6, which includes a bottom sealing assembly and a sewage filter 61. The bottom sealing assembly includes a first half-cover 62 and a second half-cover 63. The upper end of the first half-cover 62 is connected to the first arc plate 42, and the upper end of the second half-cover 63 is connected to the second arc plate 43. The lower ends of both the first half-cover 62 and the second half-cover 63 are movably connected to the connecting frame 41, so that the bottom sealing assembly can switch between an unfolded mode and a retracted mode. When the cleaning device 4 is in the closed mode and the bottom sealing assembly is in the retracted mode, the cylinder cavity 44 has a downwardly arranged lower opening 441. The first half-cover 62 and the second half-cover 63 can tightly fit against the outer wall of the supporting insulator to seal the lower opening 441 of the cylinder cavity 44. The sewage filter 61 is connected to the base 2 and has a recycling chamber. The first arc plate 42 and / or the second arc plate 43 have a through-flow port 421, and the recycling chamber communicates with the return port 421.

[0039] When the cleaning device 4 is in closed mode and the bottom sealing assembly is in retracted mode, the bottom sealing assembly blocks the lower opening 441 of the cylinder cavity 44, so that the lower end of the cylinder cavity 44 is closed. After the cleaning solution sprayed from multiple high-pressure flushing ports 4111 cleans the supporting insulator, it enters the recycling chamber through the return port 421 for recycling. The sewage filter 61 can filter the recycled sewage to realize water resource recycling and reuse, thereby reducing water resource waste.

[0040] Specifically, such as Figure 2 and Figure 3As shown, the return port 421 passes through the first arc plate 42 and is located near the lower side of the first arc plate 42. The return port 421 is connected to the recovery chamber through a hose to prevent the bottom sealing assembly from affecting the connection between the return port 421 and the recovery chamber when switching modes.

[0041] In some embodiments, such as Figure 3 As shown, the first arc plate 42 has a sealing protrusion 422 on the side facing the second arc plate 43, and the second arc plate 43 has a sealing groove 431 on the side facing the first arc plate 42. When the cleaning device 4 is in closed mode, the sealing protrusion 422 is inserted into the sealing groove 431.

[0042] The first arc plate 42 and the second arc plate 43 are inserted together to ensure the sealing of the side cavity wall of the cylinder 44, preventing the cleaning solution or cleaning water from seeping out from the contact position of the first arc plate 42 and the second arc plate 43. This can improve the cleaning effect on the supporting insulator, while reducing water waste and increasing the water recovery rate.

[0043] Optionally, a rubber gasket is provided at the contact position between the sealing protrusion 422 and the sealing groove 431, and the gasket is connected to the groove wall of the sealing protrusion 422 or the sealing groove 431; thereby improving the sealing performance at the contact position between the first arc plate 42 and the second arc plate 43.

[0044] In some embodiments, the wastewater filter 61 further includes a water purification chamber that is in communication with the liquid storage chamber.

[0045] Wastewater filtered by wastewater filter 61 is stored in the clean water chamber. After the cleaning solution performs high-pressure rinsing on the supporting insulator, the clean water in the clean water chamber is transported to the liquid container chamber to further rinse the supporting insulator, thereby cleaning solvent residue on the surface of the insulator and improving the cleaning effect.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the first half-cover 62 includes a first cover fabric 621 and a first rib 622. The upper end of the first cover fabric 621 is connected to the first arc plate 42, and the lower end of the first cover fabric 621 is connected to the first rib 622. The first rib 622 includes a plurality of first electromagnets arranged at intervals along the lower edge of the first cover fabric 621. The second half-cover 63 includes a second cover fabric 631 and a second rib 632. The upper end of the second cover fabric 631 is connected to the second arc plate 43, and the lower end of the second cover fabric 631 is connected to the second rib 632. The second rib 632 includes a plurality of second electromagnets arranged at intervals along the lower edge of the second cover fabric 631. When the plurality of first electromagnets and the plurality of second electromagnets are energized, they can attract each other in sequence to retract the lower ends of the first half-cover 62 and the second half-cover 63, so that the bottom sealing assembly switches to a retracted mode.

[0047] Specifically, such as Figure 3 and Figure 4 As shown, the first rib 622 includes a plurality of first connecting segments 6221 arranged at intervals along the lower edge of the first cover 621. The first connecting segments 6221 arranged near the connecting frame 41 are connected to the connecting seat 412 by connecting posts. Each first connecting segment 6221 is provided with a first electromagnet, that is, a plurality of first electromagnets are arranged at intervals along the lower edge of the first cover 621. The plurality of first connecting segments 6221 are provided with wires for supplying power to the plurality of first electromagnets.

[0048] The second rib 632 includes a plurality of second connecting segments 6321 arranged at intervals along the lower edge of the second cover 631. The second connecting segments 6321 arranged near the connecting frame 41 are connected to the connecting seat 412 by connecting posts. Each second connecting segment 6321 is provided with a second electromagnet, that is, a plurality of second electromagnets are arranged at intervals along the lower edge of the second cover 631. The plurality of second connecting segments 6321 are provided with wires for supplying power to the plurality of second electromagnets.

[0049] Simultaneously energizing multiple first electromagnets and second electromagnets allows the multiple first electromagnets to attract each other in sequence, and the multiple second electromagnets to attract each other in sequence as well. The first electromagnet at the end of the first rib 622 and the second electromagnet at the end of the second rib 632 are magnetically attracted, thereby shrinking the lower end of the first cover 621 and making the first rib 622 and the second rib 632 fit tightly against the outer wall of the supporting insulator, so as to achieve the effect of sealing the lower opening 441 of the cylinder cavity 44.

[0050] Optionally, both the first cover 621 and the second cover 631 are made of flexible waterproof fabric.

[0051] In some embodiments, the first rib 622 and the second rib 632 are each connected to a rubber sheet on the side of their proximity to each other for fitting against the outer wall of the supporting insulator.

[0052] The rubber sheet has a certain elasticity. When the first rib 622 and the second rib 632 contract, multiple first electromagnets and multiple second electromagnets adhere to the outer wall of the supporting insulator through the rubber sheet. This can improve the sealing performance between the first rib 622 and the second rib 632 and the outer wall of the supporting insulator, and reduce the probability of sewage seeping out from the contact points between the first rib 622 and the second rib 632 and the outer wall of the supporting insulator.

[0053] In some embodiments, the dimensions of the first rib 622 and the second rib 632 along the length of the cylinder 44 are both less than 1 cm.

[0054] It is known that the supporting insulator has multiple gaps arranged along its axial direction. By restricting the dimensions of the first rib 622 and the second rib 632, the first rib 622 and the second rib 632 can enter the gaps of the supporting insulator when they contract, thereby further improving the sealing effect of the bottom sealing assembly on the lower opening 441 of the cylinder 44 in the contraction mode.

[0055] In some embodiments, the liquid supply device 5 includes a pump body 51 and a first solution tank 52, a second solution tank 53, and a third solution tank 54 for holding cleaning solutions of different components, respectively. The outlet of the pump body 51 is connected to the liquid-containing chamber, and the first solution tank 52, the second solution tank 53, and the third solution tank 54 are all connected to the inlet of the pump body 51.

[0056] Specifically, such as Figure 1 and Figure 3 As shown, the pump body 51 is fixedly connected to the cleaning plate 411 via an "L"-shaped bracket. The outlet of the pump body 51 is connected to the liquid chamber via a pipe. The inlet of the pump body 51 is connected to the first solution tank 52, the second solution tank 53, the third solution tank 54, and the clean water chamber of the sewage filter 61 via pipes. Electric valves are provided between the first solution tank 52, the second solution tank 53, the third solution tank 54, and the sewage filter 61 and the pump body 51. The electric valves control any one or more of the first solution tank 52, the second solution tank 53, the third solution tank 54, and the sewage filter 61 to be connected to the liquid chamber, thereby controlling the solution or clean water of different components to clean the supporting insulator through the high-pressure flushing port 4111.

[0057] Optionally, the first solution tank 52, the second solution tank 53, and the third solution tank 54 are used to hold deionized water, a bio-enzyme decomposition agent, and a nano-emulsion, respectively. These three cleaning solutions can respectively clean the soot mixture, bird droppings / tree sap, and industrial oil stains adhering to the surface of the supporting insulator, thereby achieving a better cleaning effect.

[0058] In some embodiments, the robotic arm 3 includes a first arm segment 31, a second arm segment 32, and a third arm segment 33 that are movably connected in sequence. The first arm segment 31 is movably connected to the base 2, and the cleaning device 4 is connected to the third arm segment 33.

[0059] Specifically, such as Figure 5As shown, the first arm segment 31 is a telescopic arm. One end of the first arm segment 31 is rotatably connected to the base 2 via a rotating platform 34, and the other end is hinged to one end of the second arm segment 32. The other end of the second arm segment 32 is connected to a rotating seat 35, which includes a rotating end that can rotate relative to the second arm segment 32. The third arm segment 33 is hinged to the rotating end of the rotating seat 35. The end of the third arm segment 33 is hinged to a hinge seat 36, which forms the movable end of the robotic arm 3. The hinge seat 36 and the connecting seat 412 are fixedly connected by bolts. Thus, the robotic arm 3 can adjust the position of the cleaning device 4 in multiple directions and angles, making it more suitable for the complex positions of supporting insulators in the field.

[0060] It is understandable that each rotating part of the robotic arm 3 is equipped with a drive motor, and the telescopic part is equipped with a telescopic drive component (such as an electric push rod, a cylinder, etc.), which will not be elaborated here.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the walking device 1 includes a track mechanism 11 and a walking frame 12, and a plurality of spring buffers 13 are provided between the base 2 and the walking frame 12.

[0062] Specifically, such as Figure 1 and Figure 2 As shown, the cleaning equipment is driven by the track mechanism 11, which is more suitable for complex field environments; the base 2 is located on the upper side of the walking frame 12, and multiple spring buffers 13 are provided between the base 2 and the walking frame 12; the first solution tank 52, the second solution tank 53 and the third solution tank 54 are all installed on the upper side of the base 2, and the sewage filter 61 is installed on the lower surface of the base 2.

[0063] The base 2 is also equipped with a protective plate 21, which is arranged to fit the first solution tank 52, the second solution tank 53 and the third solution tank 54 and is connected to the three by bolts. When the robotic arm 3 is folded, the protective plate 21 can protect the robotic arm 3 and the cleaning device 4 to prevent flying stones from hitting them.

[0064] As an example, the operation process of the support insulator cleaning device 100 in this embodiment of the invention is as follows:

[0065] First, the cleaning equipment is moved to the area below the high-voltage tower using the tracked mechanism 11. The height and angle of the cleaning device 4 are adjusted using the robotic arm 3, so that the cleaning device 4 (in open mode) moves to the side of the support insulator to be cleaned and is controlled to approach the support insulator, so that the support insulator enters between the first arc plate 42 and the second arc plate 43. Then, the first arc plate 42 and the second arc plate 43 are controlled to rotate and move closer to switch to closed mode, forming a cylindrical cavity 44. The bottom sealing assembly switches to retracted mode, and the first rib 622 and the second rib 632 are embedded in the gaps of the support insulator and tightly clamped in the gaps of the support insulator to seal the lower opening 441 of the cylindrical cavity 44, thus completing the cleaning preparation.

[0066] Then, the pump body 51 is started, and the pump body 51 sequentially draws the cleaning solutions from the first solution tank 52, the second solution tank 53, and the third solution tank 54 into the liquid chamber, that is, the supporting insulator is cleaned by the three components of the cleaning solution in sequence. The wastewater after cleaning enters the wastewater filter 61 through the return port 421, and is temporarily stored in the clean water chamber after being filtered by the wastewater filter 61. Finally, the pump body 51 draws out the clean water in the clean water chamber of the wastewater filter 61 to rinse the surface of the supporting insulator of the residual cleaning solution, thus completing the cleaning work of the supporting insulator. By controlling the first arc plate 42 and the second arc plate 43 to rotate away, the cleaning device 4 can be separated from the cleaned supporting insulator so that the cleaning work of the next supporting insulator can be carried out.
