Description

Technical Field

[0001] This invention relates to the field of power distribution network technology, specifically to a power distribution network structure and power distribution method suitable for windy and sandy areas. Background Technology

[0002] In traditional power distribution network structures, support columns are typically fixed to ground bases, and insulators are rigidly mounted on crossarms or supports to support and isolate high-voltage conductors. These insulators are mostly made of ceramic or silicone rubber composite materials, and their skirt structure design is primarily based on electrical performance requirements under standard operating conditions, such as arc distance and creepage distance. Under normal climatic conditions, this type of power distribution network structure can meet basic insulation and mechanical load-bearing requirements.

[0003] However, in windy and sandy areas, especially in the arid desert regions of Northwest my country, strong winds carry large amounts of sand and dust particles year-round, posing a severe challenge to the insulation performance of traditional power distribution network structures. Sand and dust continuously deposit on the surface of insulator skirts under wind action, forming a dense contamination layer. This contamination layer not only reduces the hydrophobicity of the skirt surface but may also create conductive paths by absorbing moisture from the air. When ambient humidity increases (such as nighttime condensation or brief rainfall), the contamination layer becomes damp, leading to a significant increase in leakage current on the insulator surface, which can easily trigger localized arcing or even flashover accidents.

[0004] Furthermore, the sheds of traditional insulators are mostly arranged in regular concentric circles. When sand and dust particles settle vertically, they easily form continuous accumulation paths between the sheds, effectively shortening the actual creepage distance. Once the pollution accumulation reaches a critical level, even if the system operating voltage is not exceeded, a sudden drop in insulation strength may cause tripping or equipment damage. To maintain operational safety, maintenance units have to take measures such as frequent manual cleaning, live flushing, or applying anti-pollution coatings, which are not only costly but also difficult to implement in remote or harsh terrain areas.

[0005] More importantly, traditional power distribution network structures lack the ability to detect pollution levels and cannot dynamically adjust protection strategies based on the actual degree of pollution. Once insulators are covered by sand and dust, their electrical performance degradation is often insidious and gradual, only being discovered in the event of a sudden fault. Therefore, in areas with frequent sandstorms and sparse populations, the insulation reliability of traditional power distribution network structures faces long-term and systemic risks, urgently requiring fundamental improvements in structural design and functional mechanisms. Summary of the Invention

[0006] The purpose of this invention is to provide a power distribution network structure and power distribution method suitable for windy and sandy areas, so as to solve the problems mentioned in the background art.

[0011] According to the above technical solution, the lifting connection assembly includes: The nested telescopic cylinder consists of a first hollow movable cylinder and a second hollow movable cylinder that are nested and slide together. The lifting block is fixed to the top of the nested telescopic cylinder and connected to the bottom of the edge composite insulator by bolts. The lifting base block is fixed to the bottom of the nested telescopic cylinder and connected to the top of the planetary gear rotating shaft by bolts; The electric telescopic cylinder is installed inside the nested telescopic cylinder, with the cylinder body fixed to the lifting bottom block and the telescopic rod connected to the lifting top block. The corrugated expansion tube covers the outside of the nested expansion cylinder.

[0012] According to the above technical solution, the first cleaning block and the second cleaning block are composite structures and have the same structure, both including: The magnetic field responsive elastic layer is made of an elastic matrix with dispersed soft magnetic particles, and its hardness is continuously adjustable with the magnetic field strength.

The adsorbent matrix has a multi-level porous structure and solvent release function; The magnetic field generator is fixedly installed inside the magnetic field-responsive elastic layer.

[0013] According to the above technical solution, the adsorption matrix includes: The microcapsule array consists of evenly distributed elastic gas bladders that encapsulate cleaning solvents and release the solvents in response to mechanical pressure. Solvent storage cavity, connected to microcapsule array via microchannels; When the elastic airbag is compressed and contracts, solvent is injected through a one-way valve. After the solvent is released, the solvent is automatically replenished through the compression and reset action of the elastic airbag.

[0014] According to the above technical solution, it also includes a soil and waste identification and control system, including: The first optical sensor, installed at the edge of the central composite insulator skirt, is used to detect the properties of surface contamination. The second optical sensor, installed on the edge of the edge composite insulator skirt, is used to detect the properties of surface contamination. The control unit is electrically connected to the magnetic field generator and outputs signals to adjust the hardness of the cleaning block and the speed of the planetary gear set according to the type of dirt.

[0015] According to the above technical solution, the self-cleaning module is powered by a resonant non-contact energy transmission system, including: The fixed-end transmitting coil is embedded inside the support column; The mobile receiving coil is embedded inside the insulator assembly.

[0016] A power distribution method suitable for power distribution networks in windy and sandy areas includes the following steps: S1, Wind Energy Capture and Power Transmission: The wind turbine rotates when exposed to wind, which drives the sun gear to rotate via a magnetic coupler, thereby causing the planetary gears to undergo a combined motion of revolution and rotation. S2, Dynamic Cleaning Execution: The combined motion of the planetary gears drives the synchronous motion of the edge composite insulators, causing the first cleaning block and the second cleaning block to periodically contact the surface of the insulator skirts; The dirt recognition system detects the type of dirt in real time, and the control unit adjusts the hardness of the cleaning block and the speed of the planetary gear according to the nature of the dirt. S3, Insulation Co-control: The lifting connection component lifts and lowers the edge composite insulator at a preset cycle, so that its skirt and the skirt of the central composite insulator form a variable settlement path, extending the pollution settlement path. S4, Active Dust Suppression: The high-voltage generator applies a pulse voltage to the inner electrode ring, and the ionized sand and dust are adsorbed into the annular sand collection cavity by the negative pressure sand collection structure. S5, self-maintenance triggered: When the sand storage box reaches its capacity threshold, it can be replaced via a magnetic quick-release structure. The elastic airbag automatically replenishes new solvent after the cleaning block is compressed.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: Strong insulation performance: The staggered distribution of the central composite insulator and the edge composite insulator creates an interlaced settling path, effectively extending the deposition path of sand and dust particles on the insulator surface and significantly increasing the effective creepage distance. This structural design fundamentally blocks the possibility of sand and dust particles forming a continuous conductive channel, significantly enhancing the insulator's withstand voltage in sandy environments and reducing the risk of flashover.

[0018] Dynamic self-cleaning and adaptive adjustment: Based on the wind-powered planetary gear set and the lifting connection component working together, the cleaning block periodically contacts the surface of the insulator skirt, completing the automatic switching of cleaning mode. Combined with the real-time monitoring of the dirt identification and control system, the system can dynamically adjust the hardness of the cleaning block and the speed of the planetary gear, optimize the cleaning intensity for different types of dirt, realize differentiated treatment of light and heavy dirt, and significantly improve cleaning efficiency and targeting.

[0019] Active protection against sand and dust pollution: The sand and dust electric shielding system uses the strong electric field formed by the inner and outer electrode rings, combined with the radio frequency enhancement ring to optimize the electric field distribution, so that sand and dust particles are attracted or deflected by the electric field force before contacting the insulator. The negative pressure sand collection structure inside the planetary gear further generates negative pressure through the gradually narrowing Venturi channel, actively sucking in sand and dust and storing it in the detachable sand storage box, forming a dual protection of "electric field adsorption and mechanical collection", which greatly reduces the probability of sand and dust adhering to the surface of the insulator.

[0020] Reduced maintenance costs and human intervention: The resonant non-contact energy transmission system achieves wireless power supply through a fixed-end transmitting coil and a mobile-end receiving coil, eliminating the dependence on physical connections in traditional power supply methods. Combined with a magnetic quick-release structure, an automatic solvent replenishment mechanism, and an intelligent cleaning strategy, the system can operate stably for a long time without frequent manual maintenance, significantly reducing operation and maintenance costs, while avoiding the risk of equipment failure and downtime caused by sand and dust.

[0021] Enhanced environmental adaptability and reliability: All components of the device are optimized for windy and sandy environments. The planetary gear set uses wear-resistant materials and a sealed structure. The lifting assembly is equipped with a corrugated telescopic tube for dust prevention. The magnetic field response elastic layer and graded bristle array of the cleaning module adapt to complex and dirty working conditions. Through multi-dimensional collaboration of "structural resistance to wind and sand, functional pollution prevention, and intelligent self-adjustment", the device ensures long-term reliable operation in extreme environments and extends the service life of the equipment.

[0022] Energy efficiency and sustainability: The wind turbine captures natural wind energy as the main power source, and the mechanical linkage between the planetary gear set and the lifting component realizes efficient energy conversion without the need for additional energy input. The microcapsule array of the cleaning module automatically replenishes the solvent through elastic airbags, forming a closed loop. The overall design conforms to the concept of green energy utilization, reduces dependence on external energy, and provides a sustainable power facility solution for windy and sandy areas.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-14 The present invention provides a technical solution: a power distribution network structure suitable for windy and sandy areas, comprising: Support column 10, with a fixed base 11 at the bottom; The lifting sleeve seat 20 is composed of a movable sleeve ring 21 and a side wing support plate 22. The movable sleeve ring 21 is adjustable and fixed to the support column 10. Insulator group 30 includes: The central composite insulator 31 is fixed to the upper end of the side wing support plate 22, and a cable clamp 311 is provided on the top. Its core rod is made of silicone rubber composite cross-ribbed core to form multiple insulation barriers. The edge composite insulator 32 is evenly distributed around the central composite insulator 31. Its skirts are staggered with the skirts of the central insulator 31 to form a staggered settlement path. The bottom is movably connected to the lifting mechanism. Planetary gear set 40 is located at the lower end of the central composite insulator 31. The bottom of the sun gear 41 is connected to the wind turbine plate 42. The planetary gear 43 is linked to the edge composite insulator 32 through the lifting connection assembly 50. The self-cleaning module 60 includes: The first cleaning block 61 is fixed to the lower surface of the shed of the central composite insulator 31; The second cleaning block 62 is fixed to the lower surface of the skirt of the edge composite insulator 32; Among them, the central composite insulator 31 provides basic insulation protection, the edge composite insulator 32 maintains insulation strength through dynamic cleaning, the wind-driven planetary gear set 40 drives the edge composite insulator to revolve and rotate, and the lifting connection component 50 controls its lifting displacement, so that the second cleaning block 62 wipes the central umbrella skirt and the first cleaning block 61 wipes the edge umbrella skirt, achieving synergistic effect of insulation and self-cleaning. Specifically, it also includes a dust electro-shielding system 70, which comprises: The inner electrode ring 71 and the outer electrode ring 72 are coaxially arranged. The inner electrode ring 71 has a mesh conductive structure, and the outer electrode ring 72 has a needle-shaped electrode array. High voltage generator 73 is electrically connected to inner electrode ring 71, and outer electrode ring 72 is grounded; The radio frequency enhancement ring 74 is installed between the inner electrode ring 71 and the outer electrode ring 72; The polycarbonate insulating cover 75 is fixed to the upper end of the side wing support plate 22 by a vertical fixing rod 76, and encapsulates the inner electrode ring 71, the outer electrode ring 72 and the radio frequency enhancement ring 74. The dust electric shielding system 70 is a key protective component designed specifically for power distribution networks in windy and sandy areas. Its main function is to control the electric field of dust particles and provide active protection. The dust electric shielding system 70 includes an inner electrode ring 71 and an outer electrode ring 72 arranged coaxially. The inner electrode ring 71 adopts a mesh conductive structure, while the outer electrode ring 72 is a needle-shaped electrode array. This structural design creates a specific electric field distribution, causing dust particles to be directionally moved by the electric field force when passing through the electric field region. A high-voltage generator 73 is electrically connected to the inner electrode ring 71, providing continuous high-voltage power to the system, enabling the inner electrode ring 71 to form a stable electric field region. The outer electrode ring 72 is grounded, forming a complete electric field loop with the inner electrode ring 71, ensuring uniform distribution of the electric field. For stable operation, the radio frequency enhancement ring 74 is installed between the inner electrode ring 71 and the outer electrode ring 72. Its function is to enhance the stability and uniformity of the electric field, optimize the electric field distribution, and improve the capture efficiency of sand and dust particles. The presence of the radio frequency enhancement ring 74 ensures that the electric field can effectively play its role when sand and dust particles pass through, avoiding protection failure caused by uneven electric field strength. The polycarbonate insulating cover 75 is fixed to the upper end of the side wing support plate 22 by the vertical fixing rod 76, and encapsulates the inner electrode ring 71, the outer electrode ring 72, and the radio frequency enhancement ring 74. The polycarbonate insulating cover 75 plays a role in protecting the internal electrode structure, preventing external environmental factors such as rainwater and sand and dust from directly contacting the electrodes, while ensuring the enclosure of the electric field area and avoiding electric field leakage that may cause safety hazards. The dust shielding system 70 works in conjunction with other parts of the power distribution network frame. When the wind turbine 42 rotates under the influence of wind, driving the planetary gear set 40 to run, the system uses an electric field to adsorb or deflect dust particles before they reach the surface of the insulator. The dust particles are attracted to the outer electrode ring 72 under the action of the electric field and will not adhere to the surface of the insulator skirt, thus effectively preventing dust from contaminating the surface of the insulator and maintaining the insulation performance of the insulator. The system works in conjunction with the negative pressure sand collection structure of the planetary gear set 40 to form a dual protection mechanism of electric field adsorption and mechanical collection, which effectively treats the dust before it comes into contact with the surface of the insulator, greatly reducing the probability of dust adhering to the surface of the insulator, extending the service life of the insulator, and ensuring the stable operation of the power distribution network in a windy and sandy environment. Specifically, the planetary gear set 40 includes: The bottom of the sun gear 41 is connected to the wind turbine plate 42 via a magnetic coupler 47; The gear ring 44 is coaxially and fixedly sleeved on the outside of the sun gear 41; Planetary gear 43 meshes between sun gear 41 and ring gear 44; The rotating disk 45 is rotatably mounted on the upper end of the gear ring 44, and the rotating shaft 46 at the top of the planetary gear 43 passes through the rotating disk 45 and is connected to the lifting connection assembly 50; The planetary gear set 40 is the core transmission mechanism in the power distribution network frame that enables dynamic cleaning. Its ingenious design uses wind power to achieve periodic cleaning of the insulator surface. The planetary gear set 40 comprises four core components: a sun gear 41, a gear ring 44, planet gears 43, and a rotating disk 45. The sun gear 41 serves as the core power input for the planetary gear set 40. Its bottom is connected to the wind turbine plate 42 via a magnetic coupler 47, allowing the wind energy captured by the wind turbine plate 42 to be smoothly and contactlessly transferred to the planetary gear set 40. This avoids the vibration and wear problems that may result from direct mechanical connections. Simultaneously, a central composite insulator 31 is provided. The ring gear 44 is coaxially and fixedly sleeved on the outside of the sun gear 41, serving as the internal gear meshing component of the planet gears 43. Its fixed characteristic provides the necessary constraint for the revolution of the planet gears 43. The planet gears 43 are evenly distributed around the sun gear 41, meshing externally with the sun gear 41 and internally with the ring gear 44. This structure allows them to revolve around the sun gear 41 while rotating on their own axis. The rotating disk 45 is rotatably mounted on the upper end of the ring gear 44, providing support and guidance for the movement of the planet gears 43, ensuring the stability of the planet gears 43 during their revolution. The rotating shaft 46 at the top of the planet gears 43 passes through... The rotating disk 45 is connected to the lifting connection assembly 50, transmitting the compound motion of the planetary gears 43 to the lifting connection assembly 50. When the wind turbine 42 rotates due to wind, it drives the sun gear 41 to rotate through the magnetic coupler 47. The sun gear 41 drives the planetary gears 43 to perform a compound motion of revolution and rotation under the constraint of the gear ring 44. This compound motion is transmitted to the lifting connection assembly 50 through the rotating shaft 46, causing the edge composite insulator 32 to perform a periodic lifting motion synchronously. The special design of the planetary gear set 40 ensures that during the revolution, the surface of the skirt of the edge composite insulator 32 is in contact with the surface of the skirt of the central composite insulator 31. The surface makes periodic contact with the self-cleaning module 60, which, together with the first cleaning block 61 and the second cleaning block 62, achieves dynamic cleaning of the insulator skirt surface. At the same time, the control of the lifting connection component 50 enables the edge composite insulator 32 to rise and fall according to a preset cycle, blocking the path of dirt settling and preventing sand and dust from accumulating on the insulator surface. This design cleverly uses wind energy as a power source and achieves the self-cleaning function of the insulator surface through the compound motion of the planetary gear set 40. No additional energy is required, making it particularly suitable for use in power distribution grids in windy and sandy areas. It effectively extends the service life of the insulator and ensures the stable operation of the power distribution network. Specifically, the planetary gear 43 is provided with a negative pressure sand collection structure, which includes: The central negative pressure chamber 431 and the annular sand collection chamber 432 are connected by a tapering Venturi channel. The outer wall of the annular sand collection cavity 432 is evenly distributed with inverted conical micropores 433, and the inner wall is inlaid with a wear-resistant ceramic lining. The detachable sand storage box 434 is connected to the bottom of the planetary gear 43 via a magnetic quick-release structure; The negative pressure sand collection structure inside the planetary gear 43 is a key sand and dust treatment component designed specifically for windy and sandy environments. Its main function is the active adsorption and collection of sand and dust. The negative pressure sand collection structure includes a central negative pressure chamber 431 and an annular sand collection chamber 432, which are connected by a tapered Venturi channel. The tapered Venturi channel design utilizes the principle of generating negative pressure by changes in airflow velocity. When the planetary gear 43 undergoes a combined revolution and rotation driven by wind, the airflow velocity increases as it passes through the tapered Venturi channel, thereby forming a stable negative pressure area in the central negative pressure chamber 431. The outer wall of the annular sand collection chamber 432 is evenly distributed with inverted conical micropores 433. This design ensures that sand and dust can be effectively sucked in without being absorbed by micro-organisms. The inverted conical micropore structure allows sand and dust to be drawn in under negative pressure, while avoiding the problem of micropore blockage due to sand and dust accumulation. The inner wall of the annular sand collection chamber 432 is inlaid with a wear-resistant ceramic lining. This material has extremely high wear resistance and can effectively resist the continuous friction of sand and dust, extending the service life of the annular sand collection chamber 432. It is especially suitable for long-term use in windy and sandy environments. The detachable sand storage box 434 is connected to the bottom of the planetary gear 43 through a magnetic quick-release structure. This connection method allows the sand storage box 434 to be quickly and conveniently disassembled and replaced without the use of tools. When the sand storage box 434 reaches the capacity threshold, the operator can simply replace the sand storage box, which greatly improves the maintenance efficiency of the system. The negative pressure sand collection structure works in conjunction with the wind-driven system of the planetary gear set 40. When the wind turbine plate 42 rotates under the wind, driving the planetary gear set 40 to run, the combined motion of the planetary gears 43 generates airflow, which forms negative pressure through the gradually narrowing Venturi channel, causing sand particles to be sucked into the annular sand collection chamber 432. The sand is collected in the annular sand collection chamber 432. The wear-resistant ceramic lining on the inner wall protects the annular sand collection chamber 432 from wear, while the inverted conical micropores 433 ensure that the sand can smoothly enter the annular sand collection chamber 432. This design realizes the active adsorption and collection of sand before it comes into contact with the insulator surface, effectively preventing the sand from adhering to the surface of the insulator skirt, thereby maintaining the insulation performance of the insulator. At the same time, the magnetic quick-release structure design of the detachable sand storage box 434 makes system maintenance more convenient and ensures the long-term stable operation of the power distribution network in windy and sandy environments. Specifically, the lifting connection assembly 50 includes: The nested telescopic cylinder 51 consists of a first hollow movable cylinder 511 and a second hollow movable cylinder 512 that are nested and slidably engaged. The lifting block 52 is fixed to the top of the nested telescopic cylinder 51 and connected to the bottom of the edge composite insulator 32 by bolts; The lifting base block 53 is fixed to the bottom of the nested telescopic cylinder 51 and is connected to the top of the planetary gear rotating shaft 46 by bolts; The electric telescopic cylinder 54 is installed inside the nested telescopic cylinder 51, the cylinder body is fixed to the lifting bottom block 53, and the telescopic rod is connected to the lifting top block 52. The corrugated expansion tube 55 covers the outside of the nested expansion cylinder 51; The lifting connection assembly 50, as the core adjustment mechanism for intelligent cleaning of insulator surfaces in the power distribution network frame, primarily functions to precisely control the cleaning spacing and intelligently switch cleaning objects. Through the precise control of the electric telescopic cylinder 54, the lifting connection assembly 50 achieves precise vertical lifting of the edge composite insulator 32. When the electric telescopic cylinder 54 operates, the telescopic rod pushes the lifting top block 52 upwards, raising the edge composite insulator 32. At this time, the second cleaning block 62 disengages from the skirt of the central composite insulator 31, and the first cleaning block 61 disengages from the edge... The sheds of the composite insulator 32 make contact, achieving cleaning of the edge composite insulator 32. When the edge composite insulator 32 descends to its lowest position, its sheds contact the sheds of the central composite insulator 31. At this time, the second cleaning block 62 contacts the sheds of the central composite insulator 31, and the first cleaning block 61 disengages from the sheds of the edge composite insulator 32, thus achieving cleaning of the central composite insulator 31. This design ensures that under normal operating conditions, only one of the first cleaning block 61 and the second cleaning block 62 is performing cleaning operations, avoiding interference and efficiency issues that may arise from both cleaning blocks working simultaneously. The precise control capability of the electric telescopic cylinder 54 allows for accurate adjustment of the lifting height of the edge composite insulator 32, thereby controlling the distance between the cleaning block and the insulator skirt. A closer distance results in greater cleaning force and stronger dirt removal; a greater distance results in less cleaning force. This is suitable for routine maintenance with light dirt. Through this precise spacing control, the lifting connection assembly 50 achieves intelligent adjustment of cleaning intensity. The dirt recognition and control system 80 sends a signal to the control unit based on the type of dirt detected by the first optical sensor 81 and the second optical sensor 82. The signal controls the lifting and lowering amplitude of the lifting connection component 50, thereby automatically adjusting the cleaning intensity. For example, for heavier sand and dust, the system will reduce the distance between the cleaning block and the umbrella skirt to enhance the cleaning force; for lighter dirt, the spacing will be increased to avoid over-cleaning and damage to the insulator surface. The corrugated expansion tube 55 covers the outside of the nested expansion cylinder 51, effectively preventing sand and rainwater from entering the lifting mechanism, ensuring long-term stable operation in windy and sandy environments, enabling continuous and reliable operation without frequent maintenance, and greatly extending the service life of the power distribution network frame. Specifically, the first cleaning block 61 and the second cleaning block 61 are composite structures and have the same structure, both including: The magnetic field responsive elastic layer 63 is made of an elastic matrix of dispersed soft magnetic particles, and its hardness is continuously adjustable with the magnetic field strength. The hierarchical bristle array 64 includes a combined structure of main bristles 641 and nano-sub-bristles 642, with the nano-sub-bristles 642 vertically disposed on the sidewall of the main bristles 641. The adsorbent matrix 65 has a multi-level porous structure and solvent release function; A magnetic field generator 66 is fixedly installed inside the magnetic field response elastic layer 63; The first cleaning block 61 and the second cleaning block 62 are the core components of the self-cleaning module 60 of the power distribution frame. Their composite structure design realizes the intelligent cleaning function of the insulator surface, and the two have completely identical structures, working together to ensure the stable maintenance of insulation performance. The magnetic field response elastic layer 63 is made of an elastic matrix of dispersed soft magnetic particles. Its hardness can be continuously adjusted according to the applied magnetic field strength. When the pollution identification and control system 80 detects a change in the type of pollution, it sends a signal to the magnetic field response elastic layer 63, causing the hardness of the elastic layer to change dynamically. When the hardness increases, the cleaning force increases, which is suitable for working conditions with heavy sand and dust accumulation. When the hardness decreases, the cleaning force decreases, which is suitable for daily maintenance of light pollution, thus achieving precise adaptation of cleaning intensity. The hierarchical bristle array 64 includes a combination structure of main bristles 641 and nano-sub-bristles 642. The nano-sub-bristles 642 are vertically arranged on the sidewall of the main bristles 641. This layered design enables the cleaning process to have multi-scale capabilities. The main bristles 641 are responsible for removing larger particles of dirt from the surface of the umbrella skirt, while the nano-sub-bristles 642 penetrate into the microstructure of the umbrella skirt to effectively clean the surface. In addition to removing fine dust adhering to crevices, ensuring comprehensive and thorough cleaning coverage, the adsorption substrate 65 has a multi-level porous structure and solvent release function. The multi-level porous structure provides abundant adsorption space, which can efficiently capture dust particles generated during the cleaning process. The solvent release function is automatically triggered when the cleaning block is pressed, releasing the pre-stored cleaning solvent to dissolve stubborn dirt and enhance the decontamination effect. When the first cleaning block 61 or the second cleaning block 62 comes into contact with the insulator skirt, the solvent release mechanism of the adsorption substrate 65 is activated, realizing the physical and chemical synergistic removal of dirt. The three can work together. The magnetic field responsive elastic layer 63 adjusts the hardness according to the nature of the dirt, the graded bristle array 64 performs multi-scale cleaning, and the adsorption substrate 65 provides solvent assistance, together realizing the adaptive cleaning of the insulator skirt surface. Under the control of the lifting connection component 50, the first cleaning block 61 and the second cleaning block 62 alternately perform cleaning tasks, ensuring the continuity and efficiency of the cleaning operation, effectively preventing the accumulation of dust on the insulator surface, extending the service life of the insulator, and ensuring the reliable operation of the power distribution network in windy and sandy environments. Specifically, the adsorption matrix 65 includes: The microcapsule array 651 consists of evenly distributed elastic air bladders 654 that encapsulate cleaning solvents and release the solvents in response to mechanical pressure. Solvent storage cavity 652 is connected to microcapsule array 651 via microfluidic channel 653; When the elastic airbag 654 is compressed and contracts, solvent is injected through a one-way valve. After the solvent is released, the solvent is automatically replenished through the compression and reset action of the elastic airbag 654. The adsorption substrate 65, as the core functional component of the self-cleaning module 60, ingeniously integrates the sustained-release characteristics and intelligent response mechanism of microcapsule technology in its structural design, achieving precise release and automatic replenishment of the cleaning solvent. The adsorption substrate 65 comprises three key parts: a microcapsule array 651, a solvent reservoir 652, and a microchannel 653. The microcapsule array 651 consists of evenly distributed elastic gasbags 654. These elastic gasbags 654, as the core structure of the microcapsules, encapsulate the cleaning solvent. Each elastic gasbag 654 is designed with a one-way valve; when triggered by mechanical pressure or temperature changes, the elastic gasbag 654 contracts and deforms, releasing the cleaning solvent through a one-way valve. The valve injects internal cleaning solvent into the surface of the insulator skirt to dissolve and remove dirt. The solvent reservoir 652 serves as a storage space for the cleaning solvent and is connected to the microcapsule array 651 via a microchannel 653. The design of the microchannel 653 ensures that the solvent flows stably and orderly from the solvent reservoir 652 to the microcapsule array 651, providing a continuous solvent supply for filling the elastic airbag 654. A one-way valve is also provided at the end of the microchannel 653 to prevent backflow. When the elastic airbag 654 contracts under pressure, solvent is injected through the one-way valve; after release, it automatically replenishes solvent through its own compression and reset action. This design utilizes… The physical characteristics of the elastic airbag 654: When pressure is generated when the cleaning block contacts the insulator skirt, the elastic airbag 654 contracts, releasing solvent onto the skirt surface through a one-way valve. After the pressure is released, the elastic airbag 654 returns to its original shape due to its elasticity and automatically draws in new cleaning solvent from the microchannel 653, achieving solvent recycling. The adsorption substrate 65, magnetic field-responsive elastic layer 63, and hierarchical bristle array 64 work together to form a complete cleaning system. When the contamination identification and control system 80 detects the type of contamination, the control unit adjusts the hardness of the magnetic field-responsive elastic layer 63 to ensure the contact pressure between the cleaning block and the insulator skirt reaches a certain level. When the system reaches its optimal state, the elastic airbag 654 releases solvent under pressure to dissolve the dirt particles. The hierarchical bristle array 64 effectively removes the dissolved dirt particles through the combination of main bristles 641 and nano-sub-bristles 642. This design of the adsorption substrate 65 eliminates the need for external solvent replenishment during the cleaning process, enabling automatic solvent recycling through its own structure. This significantly improves the sustainability of the self-cleaning system. At the same time, the compression and reset mechanism of the elastic airbag 654 ensures a continuous supply of cleaning solvent, preventing cleaning interruptions due to solvent depletion and ensuring the long-term stable operation of the power distribution network in windy and sandy environments. Specifically, it also includes a soiling detection and control system 80, comprising: The first optical sensor 81 is installed on the edge of the shed of the central composite insulator 31 and is used to detect the properties of surface contamination. The second optical sensor 82 is installed on the edge of the shed of the edge composite insulator 32 and is used to detect the properties of surface contamination. The control unit is electrically connected to the magnetic field generator (66) and adjusts the hardness of the cleaning block and the rotation speed of the planetary gear set 43 according to the type of dirt output signal. The pollution identification and control system 80 is the core control system in the distribution network structure that enables intelligent sensing and adaptive cleaning of insulator pollution. Its main function is to accurately identify the properties of pollution on the insulator surface and dynamically optimize cleaning strategies. The pollution identification and control system 80 includes three core components: a first optical sensor 81, a second optical sensor 82, and a control unit. The first optical sensor 81 is installed at the edge of the shed of the central composite insulator 31 to detect the properties of pollution on the surface of the central composite insulator 31 in real time, including pollution type, density, and adhesion status. The second optical sensor 82 is installed at the edge of the shed of the central composite insulator 31... The edge of the shed of the composite insulator 32 is used to detect the nature of surface contamination in real time, providing dual-end contamination information to the control system. The control unit, as the core decision-making center of the system, is integrated within the controller. Based on the contamination information detected by the first optical sensor 81 and the second optical sensor 82, it comprehensively analyzes the type, degree, and distribution characteristics of the contamination, generating corresponding cleaning strategy instructions. The control unit adjusts the hardness of the cleaning block through output signals, causing the hardness of the magnetic field-responsive elastic layer 63 to dynamically change with the type of contamination: for sand and dust contamination, the system automatically increases the hardness of the cleaning block to enhance cleaning intensity; for... For light soiling, the system automatically reduces the hardness of the cleaning block to avoid over-cleaning. Simultaneously, the control unit adjusts the rotation speed of the planetary gear set 43 based on the soiling detection result. When heavy soiling is detected, the rotation speed of the planetary gear set 43 increases, increasing the contact frequency between the edge composite insulator 32 and the central composite insulator 31, accelerating soil removal. When light soiling is detected, the rotation speed of the planetary gear set 43 decreases, reducing unnecessary mechanical movement and extending equipment life. The soiling detection and control system 80, along with the self-cleaning module 60, the lifting connection assembly 50, and the planetary gear set 40, work collaboratively to form a closed-loop "perception-decision-execution" system. The system employs a ring control mechanism. When the first optical sensor 81 and the second optical sensor 82 detect dirt, the control unit immediately initiates a cleaning strategy. By adjusting the hardness of the cleaning block and the rotation speed of the planetary gear set 43, the system achieves precise removal of dirt from the insulator surface. The intelligent features of the dirt identification and control system 80 enable the distribution network frame to automatically adjust the cleaning strategy according to the real-time dirt status without manual intervention, greatly improving the self-maintenance capability of the insulator. Through continuous monitoring and intelligent adjustment, the system ensures that the insulator surface always maintains good insulation performance, extends the service life of the insulator, and ensures the safe and stable operation of the distribution network in windy and sandy environments. Specifically, the self-cleaning module 60 is powered by a resonant non-contact energy transfer system 90, and includes: The fixed-end transmitting coil 91 is embedded inside the support column 10; The mobile terminal receiving coil 92 is embedded inside the insulator assembly 30; The resonant non-contact energy transfer system 90 is a key power supply component providing stable power support for the self-cleaning module 60. Its ingenious design utilizes the principle of resonant coupling to achieve wireless power transmission, ensuring the continuous and stable operation of the self-cleaning module 60 in windy and sandy environments. The resonant non-contact energy transfer system 90 includes two core components: a fixed-end transmitting coil 91 and a mobile-end receiving coil 92. The fixed-end transmitting coil 91 is embedded inside the support column 10, serving as the system's energy source. The support column 10's structure ensures the stability of the transmitting coil 91's position. When the system is working, the fixed-end transmitting coil 91 generates a high-frequency alternating magnetic field through electromagnetic field coupling, providing the basic conditions for energy transmission. The mobile-end receiving coil 92 is embedded inside the insulator group 30, serving as the system's energy receiver. The mobile-end receiving coil 92 and the fixed-end transmitting coil 91 form a resonant coupling system. When both operate at the same resonant frequency, they can achieve high... The resonant non-contact energy transmission system 90 effectively completes wireless power transmission. Based on the principle of magnetic coupling resonance, it utilizes the magnetic field coupling between two resonant coils to achieve energy transmission. This design eliminates the need for an external power supply to the self-cleaning module 60, avoiding problems such as cable wear and poor contact that may occur with traditional power supply methods. It is particularly suitable for long-term stable operation in windy and sandy environments. The wireless power supply characteristic of the resonant non-contact energy transmission system 90 ensures a continuous and stable power supply to the first cleaning block 61 and the second cleaning block 62 during the cleaning process. This guarantees the normal operation of the hardness adjustment of the magnetic field-responsive elastic layer 63, the cleaning action of the graded bristle array 64, and the solvent release function of the adsorption substrate 65. The resonant non-contact energy transmission system 90 avoids the risk of cable wear and disconnection, making it particularly suitable for long-term application in power distribution networks in windy and sandy areas, providing safe and reliable power support for the self-cleaning module 60. A power distribution method suitable for power distribution networks in windy and sandy areas includes the following steps: S1, Wind Energy Capture and Power Transmission: The wind turbine 42 rotates under the influence of wind, which drives the sun gear 41 to rotate through the magnetic coupler 47, thereby driving the planetary gears 43 to perform a combined motion of revolution and rotation. S2, Dynamic Cleaning Execution: The combined motion of the planetary gear 43 drives the edge composite insulator 32 to move synchronously, so that the first cleaning block 61 and the second cleaning block 62 periodically contact the surface of the insulator skirt. The soil identification system 80 detects the type of soil in real time, and the control unit 82 adjusts the hardness of the cleaning block and the speed of the planetary gear according to the nature of the soil. S3, Insulation Co-control: The lifting connection assembly 50 lifts and lowers the edge composite insulator 32 according to a preset cycle, so that its skirt and the skirt of the central composite insulator 31 form a variable settlement path, extending the pollution settlement path; S4, Active Dust Suppression: The high-voltage generator 73 applies a pulse voltage to the inner electrode ring 71, and the ionized sand and dust are adsorbed into the annular sand collection chamber 432 by the negative pressure sand collection structure. S5, self-maintenance triggered: When the sand storage box 434 reaches its capacity threshold, it can be replaced via a magnetic quick-release structure. The elastic airbag 654 automatically replenishes new solvent after the cleaning block is compressed.
