Description

Technical Field

[0001] The present invention relates to the technical field of porcelain insulators, and particularly relates to a petticoat assembly and a porcelain insulator of a porcelain insulator. Background Art

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding member, which can withstand voltage and mechanical stress. There are many types of insulators with various shapes. Although the structures and outer shapes of different types of insulators are quite different, they are all composed of two major parts: an insulating part and a connecting fitting. The insulating part is usually made of glass or ceramic material. During long-term use, in order to prevent dust and dirt from adhering to the surface of the insulating part, resulting in a reduction in the insulation performance of the insulating part, manual cleaning is required.

[0003] For example, in the patent named: An Insulator Assembly Facilitating Cleaning (Patent Application No.: CN202411612698.2), an insulator assembly facilitating cleaning is disclosed. By providing a ceramic umbrella disc, a first inlet, a second inlet, an outlet, and a Tesla valve flow channel, it is possible to avoid the accumulation of dust and dirt at the corner where the glass umbrella disc contacts the steel cap, preventing the insulation effect from being reduced due to dirt on the upper surface of the glass umbrella disc. This device can well avoid the accumulation of dust and dirt, ensure the cleanliness of the glass umbrella disc itself, and can guide and accelerate natural wind and water flow to improve the cleaning effect on the upper surface of the glass umbrella disc, reducing the frequency of manual periodic cleaning and greatly reducing the manual labor intensity. However, in the actual use process of this insulator assembly, due to limited dimensions, natural wind is difficult to efficiently enter the first inlet and the second inlet, affecting the cleanliness of the insulator.

[0004] Therefore, it is very necessary to propose a petticoat assembly and a porcelain insulator of a porcelain insulator to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a petticoat assembly and a porcelain insulator of a porcelain insulator to solve the problem that in the actual use process of this insulator assembly, due to limited dimensions, natural wind is difficult to efficiently enter the first inlet and the second inlet, affecting the cleanliness of the insulator.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A petticoat assembly of a porcelain insulator, comprising:

[0007] A steel cap;

[0008] A petticoat fitting, including a glass umbrella disc and a ceramic umbrella disc. The steel cap is cemented on the top of the glass umbrella disc, and the ceramic umbrella disc is arranged on the steel cap;

[0009] An air duct, which is penetrated through the ceramic umbrella disc, and a plurality of air ducts are evenly distributed around the axis of the ceramic umbrella disc;

[0010] The wind power mechanism includes an annular box and fan blades. The annular box is fixedly connected to the bottom of the ceramic umbrella disc. An air duct is provided at the top of the annular box and is communicated with the air channel. The fan blades are fixedly connected to the bottom of the annular box;

[0011] The wind collecting mechanism includes an annular plate and an annular filter screen. The annular plate and the upper surface of the ceramic umbrella disc form a wind collecting channel for collecting wind power. The wind collecting channel conveys the wind power to the glass umbrella disc through the air duct and the wind power mechanism to blow off impurities. The annular filter screen extends under the action of wind power and stacks up after the wind stops.

[0012] Preferably, the air duct is trapezoidal, and the length and width dimensions at the top are larger.

[0013] Preferably, a closing mechanism is provided at the air duct. The closing mechanism includes a cover plate and a spring. The cover plate on the windward side moves downward under the action of wind power, and the air duct opens. The cover plates at other positions close the corresponding air ducts.

[0014] Preferably, a conveying channel communicated with the annular box is provided inside the fan blade. The bottom end of the conveying channel penetrates through the side of the fan blade facing away from the steel cap, and the bottom end of the conveying channel is inclined.

[0015] Preferably, the conveying channel gradually becomes narrower from top to bottom.

[0016] Preferably, a round rod is fixedly connected to the bottom end of the conveying channel, and a baffle is rotatably arranged on the round rod.

[0017] Preferably, the fan blade includes a hard section and a soft section. The soft section is located below the hard section, and the soft section cooperates with the steel cap by means of a magnetic component.

[0018] Preferably, a counterweight is arranged at the outer circle of the annular plate.

[0019] Preferably, a detachable structure is provided between the annular filter screen, the annular plate and the ceramic umbrella disc.

[0020] The present invention also discloses a porcelain insulator, which uses the umbrella skirt assembly of the porcelain insulator as described above, and further includes a steel foot. The steel foot is cemented to the bottom end of the glass umbrella disc. A supporting sleeve is fixedly connected to the steel foot, and the supporting sleeve is frustum-shaped and abuts against the bottom of the glass umbrella disc.

[0021] The technical effects and advantages of the present invention:

[0022] 1. By arranging structures such as an air duct and a wind collecting mechanism, the wind power sprayed on the surface of the glass umbrella disc is greater and faster, improving the self-cleaning effect. The turning of the annular plate enables the annular filter screen to extend and stack alternately, avoiding blockage and improving the use efficiency of the umbrella skirt assembly;

[0023] 2. By arranging the wind power mechanism, the conveyance of wind power and the rotation of the ceramic umbrella disc are realized simultaneously;

[0024] 3. The present invention satisfies the change of wind direction by setting structures such as a closing mechanism and multiple air ducts, and at the same time ensures the force when the wind blows out from the bottom end of the conveying channel.

[0025] 4. By setting structures such as a round rod and a baffle, the wind will not enter from the bottom end of the conveying channel, and at the same time, it does not affect the wind from blowing out from the bottom end of the conveying channel.

[0026] 5. By setting structures such as a rigid section, a soft section, and a magnetic component, the acting angle of the wind is changed, the acting range of the wind is expanded, and the cleaning of the glass umbrella tray is realized.

[0027] 6. The annular filters are stacked, so that there is a certain gap between the ring plate and the top of the ceramic umbrella tray, which is convenient for the residual water vapor to dry, and at the same time, it is convenient for the subsequent wind to enter, and the ring plate turns upward.

[0037] The present invention provides an umbrella skirt assembly of a porcelain insulator as shown in Figures 1 to 8 , which includes a steel cap 1 and umbrella skirt fittings. The umbrella skirt fittings include a glass umbrella disc 2 and a ceramic umbrella disc 3, and the outer diameter of the ceramic umbrella disc 3 is smaller than that of the glass umbrella disc 2 (refer to Figure 3 ), and the steel cap 1 is adhesively mounted on the top of the glass umbrella disc 2; a slide rail 7 is integrally formed on the outer wall of the steel cap 1, and the ceramic umbrella disc 3 is rotatably arranged on the slide rail 7, and a structure such as a ball can be arranged between the ceramic umbrella disc 3 and the slide rail 7 to improve the smoothness of the rotation of the ceramic umbrella disc 3. The ceramic umbrella disc 3 is provided to cover and block the connection between the steel cap 1 and the glass umbrella disc 2, preventing dust and dirt from accumulating at the connection between the steel cap 1 and the glass umbrella disc 2.

[0038] Since the ceramic umbrella disc 3 will rotate, it is not easy for dust and dirt to accumulate at the connection between the ceramic umbrella disc 3 and the steel cap 1.

[0039] Refer to Figure 3 , Figure 4 As shown in, an air duct 9 is provided on the ceramic umbrella disc 3. The air duct 9 penetrates the upper and lower surfaces of the ceramic umbrella disc 3, and the air duct 9 is inclined. The top end of the air duct 9 is inclined away from the axis of the ceramic umbrella disc 3, facilitating the wind to enter the air duct 9 along the inclined surface at the top end of the ceramic umbrella disc 3.

[0040] To realize the transmission of wind power and the rotation of the ceramic umbrella disc 3, a wind power mechanism cooperating with the air duct 9 is provided below the ceramic umbrella disc 3. The wind power mechanism includes a ring box 10 and a fan blade 14. The ring box 10 is fixedly connected to the bottom of the ceramic umbrella disc 3 and can rotate synchronously with the ceramic umbrella disc 3; a wind groove 11 corresponding to and communicating with the air duct 9 is opened at the top of the ring box 10, and the ring box 10 can be communicated with the air duct 9 through the wind groove 11.

[0041] The fan blade 14 is fixedly connected to the bottom of the ring box 10. A plurality of fan blades 14 are provided, and the plurality of fan blades 14 are evenly distributed around the axis of the ring box 10, and the fan blade 14 is inclined. When external wind force acts on the fan blade 14, the ceramic umbrella disc 3 will be driven to rotate through the fan blade 14 and the ring box 10. The fan blade 14 and the ring box 10 are provided to make the ceramic umbrella disc 3 rotate by using external wind force.

[0042] Refer to Figure 4As shown, a conveying channel 15 communicating with the ring box 10 is provided inside the fan blade 14, and the bottom end of the conveying channel 15 penetrates through the side of the fan blade 14 facing away from the steel cap 1. Wind can sequentially pass through the air duct 9, the wind groove 11, the ring box 10 and the conveying channel 15, and be sprayed onto the surface of the glass umbrella tray 2 to clean the surface of the glass umbrella tray 2.

[0043] During actual use, affected by external wind force, when the external wind force acts on the fan blade 14, it will drive the ceramic umbrella tray 3 to rotate through the fan blade 14 and the ring box 10; at the same time, the wind enters the inside of the air duct 9 on the windward side and sequentially passes through the wind groove 11, the ring box 10 and the conveying channel 15, and is sprayed from the bottom end of the conveying channel 15 onto the surface of the glass umbrella tray 2 to blow away impurities such as dust, achieving the effect of self-cleaning.

[0044] Moreover, the rotation of the fan blade 14, the ring box 10 and the ceramic umbrella tray 3 will drive the conveying channel 15 to move around the steel cap 1, expanding the range of the wind force and ensuring the cleaning efficiency.

[0045] The impurities blown up on the surface of the glass umbrella tray 2 will be carried away by the outdoor wind force and will no longer adhere to the surface of the glass umbrella tray 2; in addition, the ceramic umbrella tray 3 can rotate, and the centrifugal force makes it difficult for impurities to accumulate on the ceramic umbrella tray 3. Therefore, the present invention mainly considers the cleaning of the glass umbrella tray 2.

[0046] By setting the wind force mechanism, the transportation of wind force and the rotation of the ceramic umbrella tray 3 are realized simultaneously.

[0047] Refer to Figure 1 、 Figure 4 As shown, considering that only collecting wind force through the air duct 9 has limited effect, in order to improve the efficiency of collecting wind force, a wind collecting mechanism is provided above the ceramic umbrella tray 3. The wind collecting mechanism includes a ring plate 6 and an annular filter screen 8. The inner ring of the ring plate 6 is fixedly connected to the ceramic umbrella tray 3, and the ring plate 6 is located above the air duct 9 and surrounds the outside of the steel cap 1. A collecting channel for collecting wind force is formed between the ring plate 6 and the upper surface of the ceramic umbrella tray 3. The ring plate 6 can be made of but not limited to insulating rubber material. Since the ring plate 6 surrounds the outside of the steel cap 1, the collecting channel also surrounds the outside of the steel cap 1, and a 360° wind collecting effect can be achieved to meet the change of wind direction. When wind appears, the position of the ring plate 6 on the windward side will be turned up under the influence of the wind force; after the wind force stops, the ring plate 6 will swing downward to reset.

[0048] During specific use, a counterweight block or the like (not shown in the figure) can be provided at the outer ring of the ring plate 6 to make the ring plate 6 reset quickly.

[0049] Refer to Figure 4As shown in the figure, the annular filter screen 8 surrounds the outside of the steel cap 1. The top end of the annular filter screen 8 is fixedly connected to the lower surface of the ring plate 6, and the bottom end of the annular filter screen 8 is fixedly connected to the upper surface of the ceramic umbrella tray 3. By setting the annular filter screen 8, impurities in the external wind force can be filtered to prevent impurities from entering the interior of structures such as the air duct 9, avoiding blockage. Moreover, the annular filter screen 8 limits the ring plate 6 to prevent the ring plate 6 from flipping excessively and affecting subsequent use.

[0050] When there is wind force, the position of the ring plate 6 on the windward side will flip upward under the influence of the wind force. At this time, the collection channel at this place is in a V shape, and the opening is opposite to the wind force. Compared with the air duct 9, setting the collection channel will allow more wind force to enter structures such as the air duct 9 and the ring box 10, and the wind force sprayed on the surface of the glass umbrella tray 2 is greater and faster, thereby improving the self-cleaning effect. The annular filter screen 8 extends, and the annular filter screen 8 filters impurities, and the impurities will accumulate on the surface of the annular filter screen 8; when the wind force stops or this place rotates to the leeward side, the ring plate 6 swings downward at this place, and the annular filter screen 8 stacks. The extension and stacking are switched multiple times so that impurities are not easily accumulated. Moreover, when the ceramic umbrella tray 3 rotates, the impurities are thrown off by centrifugal force and taken away by the external outdoor wind force to avoid blockage.

[0051] The annular filter screen 8 and the ring plate 6, the ceramic umbrella tray 3 can be set as a detachable structure, which is convenient for replacing the annular filter screen 8 and can be adjusted according to the specific use situation.

[0052] In actual use, at the position on the windward side, the collection channel receives wind force, and the wind force passes through the wind groove 11, the ring box 10 and the conveying channel 15 in sequence, and is sprayed from the bottom end of the conveying channel 15 onto the surface of the glass umbrella tray 2 to blow off the impurities on the surface of the glass umbrella tray 2. And the annular filter screen 8 extends, and at the same time the conveying channel 15 moves around the steel cap 1; after the wind force stops, the ring plate 6 swings downward, and the annular filter screen 8 stacks.

[0053] And the annular filter screen 8 stacks, making there be a certain gap between the ring plate 6 and the top of the ceramic umbrella tray 3, which is convenient for the residual water vapor to dry, and at the same time convenient for the subsequent wind force to enter and the ring plate 6 to flip upward.

[0054] Through the setting of structures such as the air duct 9 and the air collection mechanism in the present invention, the wind force sprayed on the surface of the glass umbrella tray 2 is greater and faster, improving the self-cleaning effect, and the flipping of the ring plate 6 makes the annular filter screen 8 extend and stack to switch, avoiding blockage.

[0055] Even if water vapor and the like enter positions such as the air duct 9, they can be discharged from the bottom end of the conveying channel 15 under the influence of wind force, and positions such as the air duct 9 are quickly dried.

[0056] Refer to Figure 4As shown in the figure, the air duct 9 is trapezoidal, with larger length and width dimensions at the top, so that the top of the air duct 9 has a larger air-collecting area, while the length and width dimensions at the bottom of the air duct 9 are smaller, so that the wind speed will increase when the wind passes through the air duct 9.

[0057] Referring to Figure 2 As shown in the figure, to meet the change of wind direction, a plurality of air ducts 9 are provided. The plurality of air ducts 9 are evenly distributed around the axis of the ceramic umbrella disc 3. A closing mechanism is provided at the wind groove 11. The closing mechanism includes a cover plate 12 and a spring 13. The cover plate 12 cooperates with the wind groove 11. The top end of the spring 13 is fixedly connected to the bottom of the cover plate 12, and the bottom end of the spring 13 is fixedly connected to the inner wall of the ring box 10. The cover plate 12 and the spring 13 are provided to close the wind groove 11.

[0058] During actual use, the cover plate 12 at the windward side is pushed downward by the wind force, and the spring 13 contracts, and the wind groove 11 at this place is opened; while the cover plates 12 at other positions close the corresponding wind grooves 11 under the elastic supporting force of the spring 13, so that the wind force entering the inside of the ring box 10 will not be ejected reversely from the wind grooves 11 at other positions, thereby ensuring the strength of the wind force when it is ejected from the bottom end of the conveying channel 15.

[0059] By setting structures such as the closing mechanism and a plurality of air ducts 9, the present invention meets the change of wind direction and at the same time ensures the strength of the wind force when it is ejected from the bottom end of the conveying channel 15.

[0060] Referring to Figure 2 As shown in the figure, the conveying channel 15 gradually narrows from top to bottom. When the wind force flows downward through the conveying channel 15, the wind speed will increase, thereby ensuring the cleaning effect.

[0061] Setting the above structures has effects such as accelerating the wind force and expanding the scope of the wind force action, and has obvious advantages compared with only using the outdoor natural wind force.

[0062] The bottom end of the conveying channel 15 is inclined and inclined away from the axis of the steel cap 1, so that the wind force can better act on the surface of the glass umbrella disc 2 and can be adjusted according to the specific use situation. A round rod 19 is fixedly connected to the inner wall of the bottom end of the conveying channel 15, and a baffle 20 is rotatably arranged on the round rod 19. Referring to Figure 7As shown, the bottom end of the conveying channel 15 is inclined, so that the baffle 20 cannot swing clockwise and can only swing counterclockwise. When the external wind force acts on the bottom end of the conveying channel 15, the baffle 20 will close the bottom end of the conveying channel 15, preventing the wind force from entering through the bottom end of the conveying channel 15. When the wind force passes through the wind groove 11, the ring box 10 and the conveying channel 15 in sequence and sprays from the bottom end of the conveying channel 15 onto the surface of the glass umbrella disc 2, the wind force will push the baffle 20 to swing counterclockwise, opening the bottom end of the conveying channel 15 without affecting the ejection of the wind force. After the wind force stops, due to its own gravity, the baffle 20 naturally swings down to close the bottom end of the conveying channel 15.

[0063] In actual use, a torsion spring or other structure can be provided on the round rod 19 to assist the reset of the baffle 20. The torsion spring is a common existing technology and will not be elaborated here.

[0064] By providing structures such as the round rod 19 and the baffle 20, the wind force will not enter through the bottom end of the conveying channel 15, and at the same time, it does not affect the ejection of the wind force from the bottom end of the conveying channel 15.

[0065] Refer to Figure 4 As shown in [[ ]], to expand the range of the wind force effect and achieve coverage of the glass umbrella disc 2, the fan blade 14 includes a rigid section 1401 and a soft section 1402. The soft section 1402 is located below the rigid section 1401. The rigid section 1401 can be made of, but is not limited to, rigid plastic, and the soft section 1402 can be made of, but is not limited to, rubber material and is deformable. Both the rigid section 1401 and the soft section 1402 have insulating properties.

[0066] Among them, a part of the soft section 1402 is connected to the steel cap 1 by a magnetic force component. The magnetic force component includes a first magnet 16 and a second magnet 17. There are multiple first magnets 16, and the first magnets 16 are fixedly embedded on the corresponding soft sections 1402. The first magnets 16 are located on the side of the soft section 1402 close to the steel cap 1.

[0067] In addition, the fan blades 14 fixedly embedded with the first magnets 16 and the fan blades 14 not fixedly embedded with the first magnets 16 are arranged alternately (refer to Figure 8 ).

[0068] The second magnets 17 are fixedly embedded on the outer wall of the steel cap 1. There are multiple second magnets 17, and the multiple second magnets 17 are evenly distributed around the axis of the steel cap 1. When the first magnet 16 and the second magnet 17 are close, the magnetic properties of the mutually approaching surfaces of the first magnet 16 and the second magnet 17 are the same, and they are in a repulsive fit.

[0069] In actual use, when the fan blade 14, the ring box 10, and the ceramic umbrella disc 3 rotate, the fan blade 14 rotates synchronously.

[0070] The fan blade 14 is fixedly embedded with the first magnet 16: when the first magnet 16 and the second magnet 17 are close to each other, the bottom end of the corresponding soft segment 1402 is inclined away from the steel cap 1 due to the repulsive force, so that the opening angle of the bottom end of the conveying channel 15 changes; when the first magnet 16 and the second magnet 17 are offset, the corresponding soft segment 1402 is reset due to its own elastic force, and then cooperates with the next second magnet 17, and the opening angle of the bottom end of the conveying channel 15 changes back and forth, thereby expanding the range of wind action.

[0071] The fan blade 14 without the first magnet 16: the bottom opening angle of the conveying channel 15 remains unchanged, and the position of the bottom end of the soft section 1402 that is inclined away from the steel cap 1 and cannot be covered is cleaned, thereby achieving coverage and cleaning of the glass umbrella plate 2.

[0072] By providing structures such as the hard segment 1401 , the soft segment 1402 and the magnetic component, the wind action angle is changed, the wind action range is expanded, and the glass umbrella plate 2 is covered and cleaned.

[0073] In addition, the magnetic forces of the plurality of first magnets 16 may be arranged to be different in magnitude, so as to adjust the inclination of the bottom end of the soft segment 1402 , which may be adjusted according to specific usage conditions.

[0074] The present invention also proposes a porcelain insulator, which uses the above-mentioned umbrella skirt assembly of the porcelain insulator, and also includes a steel foot 4, which is glued to the bottom end of the glass umbrella plate 2, and a ball socket 5 is provided on the steel cap 1. When two porcelain insulators are connected, the steel foot 4 cooperates with the corresponding ball socket 5.

[0075] The lower surface of the glass umbrella plate 2 is provided with a first skirt 21 and a second skirt 22 in sequence from the center to the edge. The height of the second skirt 22 is greater than that of the first skirt 21, which plays a role in enhancing insulation performance, waterproofing and anti-fouling effects.

[0076] A support sleeve 18 is fixedly connected to the steel foot 4, and the support sleeve 18 is in a truncated cone shape with a small outer diameter at the bottom. The support sleeve 18 abuts against the bottom of the glass umbrella plate 2 to support the glass umbrella plate 2 and improve the strength and stability of the porcelain insulator.
