[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides Figure 1 - Fig.11 A high-voltage porcelain insulator with a hydrophobic structure on the surface is shown, comprising an insulating part 1, a porcelain part 2, a steel cap 3 and a steel foot 4. The porcelain part 2 is fixedly arranged on the outer wall of the insulating part 1 at equal intervals. The insulating part 1 is the core part of the insulator, and its main function is to provide electrical insulation to ensure that there is no electrical contact between the conductor and the grounding part, such as a pole tower, thereby preventing current leakage.

[0037] Porcelain part 2, also known as umbrella skirt, is the part of the surface of the insulator and is fixed to the outer wall of the insulating part 1 in an equidistant manner. The main function of porcelain part 2 is to increase the creepage distance of the insulator, improve the electrical insulation performance, and provide sufficient electrical clearance under severe weather conditions to prevent flashover and arcing.

[0038] The steel cap 3 is fixedly arranged on the top of the insulating member 1, and its main function is to connect the conductor and ensure the connection between the conductor and the insulator.

[0039] The steel foot 4 is fixedly arranged at one end of the insulating member 1 away from the steel cap 3, corresponding to the steel cap 3. The main function of the steel foot 4 is to connect the insulator with the pole tower or other grounded parts to ensure that the insulator can be stably installed in the power system.

[0040] A sleeve 5 is fixedly provided on the outer wall of the insulating component 1, and a hydrophobic structure for repelling water from the surface of the porcelain component 2 is provided on the sleeve 5. The main purpose is to perform hydrophobic treatment on the porcelain component 2 on the surface of the insulator, which helps water to flow quickly through the surface of the porcelain component 2, thereby effectively preventing rainwater from accumulating on the surface of the porcelain component 2. When rainwater flows through the surface of the insulator, it can also cool down and dissipate the heat generated by the porcelain component 2 during operation.

[0041] The hydrophobic structure includes a fixing plate 601, which is fixedly arranged on the surface of the ceramic component 2. The diameter of the fixing plate 601 is larger than the diameter of the ceramic component 2 to ensure that when rainwater drops from a high place, it first contacts the fixing plate 601, thereby avoiding direct contact between the rainwater and the remaining surface of the ceramic component 2 and reducing direct erosion of the surface of the ceramic component 2 by rainwater.

[0042] The surface of the fixing plate 601 is equidistantly fixed with a plurality of protrusions 602. The protrusion 602 structure can not only make rainwater slide down quickly when it contacts the fixing plate 601, thereby reducing the residence time of rainwater on the fixing plate 601 and avoiding water accumulation problems, but the protrusion 602 structure can also increase the roughness of the surface of the fixing plate 601, thereby increasing the contact area with rainwater, making it easier to disperse and drain rainwater, further accelerating the discharge of rainwater. Secondly, the protrusion 602 structure can also form tiny air gaps on the surface of the fixing plate 601. These gaps can reduce the adhesion of the water film on the fixing plate 601, making it easier for rainwater to slide down and reducing the possibility of residual water stains.

[0043] The top of the sleeve 5 is fixed to the bottom of the steel cap 3, and the side of the fixing plate 601 close to the sleeve 5 is fixed to the sleeve 5. The outer wall of the porcelain part 2 is connected with a heat-conducting column 8. The heat-conducting column 8 not only optimizes the thermal conductivity of the insulator, so that the heat generated by the porcelain part 2 can be quickly transferred to the fixing plate 601, and then dissipated through the fixing plate 601, thereby improving the heat dissipation efficiency of the insulator. The setting of the heat-conducting column 8 also enhances the connection strength between the porcelain part 2, the insulating part 1 and the steel cap 3, and improves the stability of the entire insulator structure.

[0044] Furthermore, when the heat generated by the porcelain part 2 during operation is conducted to the bottom of the fixed plate 601 through the heat-conducting column 8, a cavity 603 is opened on the inner wall of the fixed plate 601 for storing rainwater, and a plurality of drain ports 604 are opened at equal intervals on the outer wall of the fixed plate 601, and the drain ports 604 are connected to the cavity 603. A plurality of water inlets 605 are opened at equal intervals on the surface of the fixed plate 601, and the water inlets 605 are connected to the cavity 603. The drain ports 604 are arranged in an arc shape, and are gradually arranged from low to high on the side close to the cavity 603, so that water can flow out of the cavity 603 more smoothly, thus avoiding the problem of water accumulation.

[0045] When it rains, rainwater drops on the steel cap 3, then flows along the surface of the steel cap 3, and finally flows into the water inlet 605 on the surface of the fixing plate 601. These water inlets 605 are connected with the cavity 603 inside the fixing plate 601, so the rainwater can smoothly enter the cavity 603. After the rainwater enters the cavity 603, it contacts with the cavity 603, effectively absorbs and takes away the heat conducted from the fixing plate 601, and then, as the rainwater flows out along the gradually rising drain port 604, the heat is also discharged together, thereby achieving effective cooling and heat dissipation of the porcelain part 2, and utilizing the natural flow of rainwater to achieve the purpose of cooling and heat dissipation without the need for additional energy consumption.

[0046] Taking into account the situation in non-rainy weather, a plurality of air inlets 9 are equidistantly provided on the outer wall of the fixing plate 601, and the air inlets 9 are connected with the cavity 603 and the drain port 604. When wind blows toward these air inlets 9, the wind will enter the cavity 603 and circulate in the cavity 603. The wind can effectively take away the heat conducted by the fixing plate 601 through the heat-conducting column 8, and discharge the heat through the drain port 604, thereby providing effective heat dissipation effect for the porcelain component 2 even in the absence of rain.

[0047] In order to ensure the stability of the ceramic part 2 in an alkaline rainwater environment, its surface should be protected by coating an anti-corrosion layer.

[0048] Furthermore, considering that rainwater is alkaline and the inner wall of the fixed plate 601 is easily corroded due to long-term contact with alkaline rainwater, a de-alkali structure for removing alkali from rainwater is provided on the surface of the fixed plate 601. When rainwater enters the water inlet 605, it will first be processed by the de-alkali structure to simplify the alkaline components in the rainwater, thereby reducing the corrosiveness of the rainwater.

[0049] The alkali removal structure includes a water storage frame 701, which collects and stores rainwater that flows through the steel cap 3 and drips into the water inlet 605. There are multiple water storage frames 701 that are equidistantly fixed on the surface of the fixed plate 601. The inner wall of the water inlet 605 is rotatably connected to a first rotating shaft 702, and a first opening and closing leaf 703 is fixed to the outer wall of the first rotating shaft 702. The outer wall of the first rotating shaft 702 is sleeved with a first torsion spring, one end of the first torsion spring is fixed to the first opening and closing leaf 703, and the other end of the first torsion spring is fixed to the inner wall of the water inlet 605.

[0050] When rain drops into the water storage frame 701, it will first contact the first hinge leaf 703. In the initial state, the first hinge leaf 703 will temporarily block the rain, causing the rain to gradually accumulate in the water storage frame 701. As the rain continues to accumulate, when the water level exceeds the preset threshold of the water storage frame 701, the weight of the rain will be enough to compress the first torsion spring, causing it to deform. This deformation causes the first rotating shaft 702 connected to the first torsion spring to start rotating, thereby driving the first hinge leaf 703 to open. When the first hinge leaf 703 opens, the rainwater previously accumulated on it and the rainwater that flows in subsequently can flow smoothly into the water inlet 605, and further accumulate on the inner wall of the water inlet 605. The first torsion spring will restore its original shape, thereby driving the first hinge leaf 703 to close again, preparing for the next round of rainwater inflow.

[0051] The inner wall of the water inlet 605 is filled with an activated carbon adsorption layer 704. The high specific surface area and porosity of the activated carbon can effectively adsorb alkaline substances and impurities in rainwater. When rainwater flows into the alkali removal structure through the water inlet 605, the activated carbon adsorption layer 704 will quickly adsorb the alkaline components in the rainwater, such as carbonates, bicarbonates, etc., thereby significantly reducing the alkalinity of the rainwater.

[0052] A second rotating shaft 705 is rotatably provided on the side of the inner wall of the water inlet 605 away from the first rotating shaft 702, and a second opening and closing leaf 706 is fixedly provided on the outer wall of the second rotating shaft 705. A second torsion spring is sleeved on the outer wall of the second rotating shaft 705, and one end of the second torsion spring is fixed to the inner wall of the water inlet 605, and the other end of the second torsion spring is fixed to the second opening and closing leaf 706. At this time, the rainwater that has been initially collected will be deeply processed through the activated carbon adsorption layer 704, which effectively absorbs alkaline substances in the rainwater, such as carbonates, bicarbonates, etc., thereby significantly reducing the alkalinity of the rainwater.

[0053] As the rainwater continues to flow in, the rainwater on the first hinge leaf 703 gradually accumulates. When the weight of the rainwater accumulates to a certain extent, it will compress the first torsion spring again, causing the first rotating shaft 702 to rotate, and then open the first hinge leaf 703. At this time, the rainwater accumulated on the first hinge leaf 703 will quickly flow into the water inlet 605. At the same time, the newly entered rainwater begins to contact and act on the second hinge leaf 706. As the weight of the rainwater increases, the second torsion spring begins to be compressed, causing the second rotating shaft 705 to rotate, driving the second hinge leaf 706 to open. During the rotation process, the second hinge leaf 706 will guide the rainwater treated by the activated carbon adsorption layer 704 out of the cavity 603 and discharge it through the drain outlet 604.

[0054] Furthermore, considering that the dust attached to the surface of the porcelain part 2 is not easy to remove, a cleaning structure for cleaning the surface of the porcelain part 2 is provided on one side of the sleeve 5 and the steel foot 4. The weight of the stored rainwater is utilized to clean the dust on the surface of the porcelain part 2 through reciprocating motion. When a certain amount of rainwater is stored, its weight will drive the cleaning structure to work, wiping the surface of the porcelain part 2 back and forth to remove the dust. This not only improves the cleaning efficiency, but also realizes the effective use of rainwater, making the entire structure more environmentally friendly.

[0055] The cleaning structure includes a support rod 101, which is fixedly arranged on one side of the sleeve 5, one end of the support rod 101 is fixed to the outer wall of the steel foot 4, a sliding rod 102 is fixedly arranged on the inner wall of the support rod 101, a moving part 103 is slidably arranged on the sliding rod 102, and fixing parts 104 are fixedly arranged on both sides of the moving part 103, a sponge 105 is fixedly arranged on the side of the fixing part 104 close to the porcelain part 2, the sponge 105 is in contact with the outer wall of the porcelain part 2, and the side of the sponge 105 away from the fixing part 104 is arranged in a wavy shape. When the movable part 103 slides downward and the fixed part 104 drives the sponge 105 to slide along the surface of the porcelain part 2, the wavy structure enables the sponge 105 to deform quickly and fit closely to the irregular shape of the surface of the porcelain part 2, ensuring a comprehensive and uniform cleaning effect. These water holes 106 can allow rainwater to penetrate evenly during the cleaning process, ensuring the wettability and cleaning power of the sponge 105. At the same time, the water holes 106 can also effectively remove excess water and dirt absorbed by the sponge 105 during the cleaning process, maintaining its cleaning performance and service life.

[0056] Taking into account the possibility of damage to the sponge 105 after long-term use, a first magnet is fixedly provided on the side of the fixing member 104 close to the sponge cover, and a second magnet is provided on the side of the sponge 105 close to the fixing member 104. The north pole of the first magnet attracts the south pole of the second magnet, and the sponge 105 can be quickly replaced through the magnetic attraction setting.

[0057] The inner wall of the moving part 103 is provided with a water outlet groove 107, and the two water outlet grooves 107 are both inclined so that rainwater can be discharged quickly;

[0058] The inner wall of the movable member 103 is rotatably provided with a third rotating shaft 108, and the outer wall of the third rotating shaft 108 is fixedly provided with a third opening and closing leaf 109. The outer wall of the third rotating shaft 108 is sleeved with a third torsion spring, one end of the third torsion spring is fixed to the third opening and closing leaf 109, and the other end is fixed to the inner wall of the movable member 103. When rainwater drops on the third opening and closing leaf 109, the rainwater will be effectively stored. Once the stored rainwater reaches a certain amount, that is, the water level is above the movable member 103, the gravity of the rainwater will naturally act to push the movable member 103 to move smoothly downward along the sliding rod 102. In this process, the movable member 103 will drive the sponge 105 to be in close contact with the surface of the porcelain member 2. Through the softness and adsorption of the sponge 105, the dust and dirt on the surface of the porcelain member 2 can be effectively cleaned.

[0059] It should be noted that the moving part 103, the sliding rod 102 and the supporting rod 101 are all coated with an anti-corrosion layer, and the anti-corrosion layer is a prior art and will not be described in detail here.

[0060] A locking piece 110 is fixedly provided on the side of the third rotating shaft 108 close to the support rod 101, and the locking piece 110 contacts the outer wall of the movable member 103; a rotating rod 111 is rotatably provided on the side of the movable member 103 close to the locking piece 110; a threaded groove 112 is provided on the rotating rod 111, and an extrusion piece 113 is movably connected on the threaded groove 112, and the extrusion piece 113 is in extrusion contact with the locking piece 110; an end of the rotating rod 111 away from the threaded groove 112 is rotatably connected to a gear 114 through a one-way bearing; a rack 115 is fixedly provided on the side of the support rod 101 close to the gear 114; a spring 116 is fixedly provided on the inner wall of the support rod 101, and one end of the spring 116 is fixed to the bottom of the movable member 103.

[0061] During operation, when rainwater gradually accumulates and is stored in the movable part 103, once the water level approaches or is about to submerge the movable part 103, the stored rainwater and the continuously falling rainwater work together to form sufficient gravity, driving the movable part 103 to slide smoothly downward along the slide rod 102. During this process, the movable part 103 will compress the spring 116 connected to it, and at the same time drive the fixed part 104 to move downward synchronously. The fixed part 104 then brings the sponge 105 to squeeze and contact the surface of the porcelain part 2, ensuring effective cleaning between the sponge 105 and the porcelain part 2. As the sponge 105 contacts the surface of the porcelain part 2, the dust and dirt attached to the surface of the porcelain part 2 are wiped off.

[0062] When the moving member 103 slides downward along the slide bar 102 so that the gear 114 is released to the rack 115, the rack 115 drives the gear 114 to rotate, and the rotation of the gear 114 causes the rotating rod 111 to rotate, and the rotation of the rotating rod 111 causes the extrusion sheet 113 to slide along the thread groove 112 toward the direction of the gear 114, thereby releasing the contact with the locking sheet 110, and the third hinge leaf 109 is compressed by the weight of the rain water to compress the third torsion spring, so that the third rotating shaft 108 rotates to cause the third hinge leaf 109 to rotate, and the rotation of the third hinge leaf 109 causes the rain water to leak out from the third hinge leaf 109 and be discharged along the water outlet trough 107, and at this time, after the rain water in the moving member 103 is discharged, the third torsion spring recovers its deformation, so that the third rotating shaft 108 brings the third hinge leaf 109 back to its original position, and then the spring 116 recovers its deformation and begins to push the moving member 103 to slide upward along the slide bar 102;

[0063] When the movable part 103 slides upward along the slide rod 102 to reset due to the thrust of the spring 116, the gear 114 contacts the rack 115 again, and the rack 115 drives the gear 114 to rotate again. The rotation of the gear 114 drives the rotating rod 111 to rotate, so that the extrusion plate 113 slides along the thread groove 112 toward the locking plate 110. As the gear 114 rotates, it continues to drive the rotating rod 111 to rotate, so that the extrusion plate 113 slides along the thread groove 112 and is squeezed into contact with the locking plate 110, thereby limiting the third rotating shaft 108, so that it can reset upward and store an appropriate amount of rainwater again to drive the sponge 105 to automatically reciprocate and clean the surface of the porcelain part 2.
