Description

Technical Field

[0001] The present invention relates to the field of ceramic insulators, in particular to a disc-shaped ceramic insulator and a fixing disc thereof. Background Art

[0002] Ceramic insulators are insulators made of electrical ceramics and are commonly used on utility poles and high-voltage power line connection towers to increase creepage distance.

[0003] Ceramic insulators play a vital role in power systems. They are designed to support and secure conductors, ensuring that current flows only along the conductors and does not leak through the insulators to the ground or other objects. Due to the excellent insulating properties and mechanical strength of ceramic materials, ceramic insulators are widely used in various power equipment and transmission lines.

[0004] The structure of ceramic insulators is divided into ceramic umbrella disc, steel feet and iron cap. The steel feet, iron cap and ceramic umbrella disc are bonded together with cement. During the bonding process, since it takes a certain amount of time for the cement to solidify itself, if the cement collapses, it is easy to cause the steel feet and iron cap to fall over, resulting in the position of the finished steel feet and iron cap to tilt, affecting the quality of the insulator. If a clamping mechanism is used to protect the steel feet and iron cap vertically, it will increase production costs.

[0005] Therefore, it is necessary to propose a disc-shaped ceramic insulator and a fixing disc thereof to solve the above problems. Summary of the Invention

[0006] The object of the present invention is to provide a disc-shaped ceramic insulator and a fixing disc thereof, so as to solve the problem that the steel leg, the iron cap and the ceramic umbrella disc are bonded together by cement. During the bonding process, since the cement takes a certain amount of time to solidify itself, if the cement collapses, it is easy to cause the steel leg and the iron cap to fall over, resulting in the position of the finished steel leg and the iron cap being tilted, affecting the quality of the insulator. If a clamping mechanism is used to vertically protect the steel leg and the iron cap, the production cost will increase.

[0007] To achieve the above object, the present invention provides the following technical solution: a disc-shaped ceramic insulator includes a four-shade insulator, an iron cap, and a steel foot, wherein the outer side of the four-shade insulator is provided with a first shed, a second shed, a third shed, and a fourth shed in sequence from top to bottom, the iron cap is sleeved on the top of the four-shade insulator, and the first shed is located below the iron cap, the radius of the first shed is smaller than the radius of the second shed, and the top of the iron cap is provided with a mounting groove;

[0008] The steel foot is arranged at the bottom end of the inner part of the four-umbrella insulator, and a fixing column is threadedly installed on the top of the steel foot. The top end of the fixing column extends out of the mounting slot, and a casting slot is provided on the top end of the fixing column. Two discharge holes are provided on the outer side of the fixing column along the height direction. The upper discharge hole is connected to the four-umbrella insulator and the iron cap, and the lower discharge hole is connected to the four-umbrella insulator and the steel foot. Cement is poured between the four-umbrella insulator and the iron cap and between the four-umbrella insulator and the steel foot.

[0009] A plurality of reinforcing ribs are fixed to the bottom end of the inner portion of the four-umbrella insulator, and one end of the plurality of reinforcing ribs contacts the outer side of the steel foot.

[0010] Preferably, there is a distance between the first umbrella skirt, the second umbrella skirt, the third umbrella skirt and the fourth umbrella skirt, the radius of the first umbrella skirt is larger than the radius of the bottom end of the iron cap, and the radii of the second umbrella skirt, the fourth umbrella skirt, the third umbrella skirt and the first umbrella skirt are arranged from large to small.

[0011] Preferably, the discharge hole is communicated with the interior of the casting trough, an external thread is provided on the outer side of the protruding end of the fixing column, a mounting opening is provided at the bottom end of the steel foot, and the external thread is threadedly installed inside the mounting opening.

[0012] Preferably, through holes are provided on both sides of the iron cap, a first insertion hole is provided on the outer side of the steel foot, and a first bolt is installed between the first insertion hole and the through hole.

[0013] Preferably, a through hole for the fixing column to pass through is provided at the bottom end of the installation groove, and a threaded opening for the bottom end of the fixing column to threadably engage is provided at the top end of the steel foot.

[0014] Preferably, a gap is left between the first umbrella skirt and the iron cap.

[0015] The present invention also discloses a fixed disk, including a fixed assembly, wherein the fixed assembly includes a first chuck and a second chuck, the first chuck and the second chuck are cylindrically sleeved on the outside of the cable, the outsides of the first chuck and the second chuck are connected to a fixed plate, and a second bolt is arranged between the two corresponding fixed plates.

[0016] Preferably, an insulating sleeve is fixed on the inner side of the first chuck and the second chuck, a tripod is fixed to the bottom end of the second chuck, a third bolt is installed between the tripods, a fixing ring is sleeved on the outer side of the third bolt, a connecting column is fixed on the bottom end of the fixing ring, a sleeve is slidingly sleeved on the outer side of the connecting column, and the sleeve is set to a T-shape corresponding to the mounting groove.

[0017] Preferably, a fixing screw is provided on the outside of the sleeve, and a plurality of docking holes are opened on the outside of the connecting column along the height direction, and one end of the fixing screw is fitted into the inside of the docking hole.

[0018] Preferably, a second plug hole corresponding to the through hole is provided at the bottom end of the outer side of the sleeve.

[0019] The technical effects and advantages of the present invention are as follows:

[0020] 1. After two four-umbrella insulators are connected up and down, the steel leg of one of the four-umbrella insulators is inserted into the iron cap of the other four-umbrella insulator. By inserting a first bolt between the corresponding first insertion hole and the through hole, the connection between the iron cap and the steel leg can be completed, thereby improving the structural strength and stability. Since it is connected by the first bolt, it is convenient for later disassembly. Furthermore, after the two four-umbrella insulators are connected up and down, the steel leg of the four-umbrella insulator on the upper side can be connected to the fixing column of the four-umbrella insulator on the lower side, thereby further improving the connection strength.

[0021] 2. In the actual operation of the present invention, a steel foot can be installed at the bottom end of the four-umbrella insulator, an iron cap can be installed at the top end of the four-umbrella insulator, and a fixing column can be threadedly installed between the four-umbrella insulator, the iron cap and the steel foot to enhance the strength and stability of the overall structure. At the same time, the verticality between the four-umbrella insulator, the iron cap and the steel foot can be maintained through the connection of the fixing column.

[0022] 3. Furthermore, cement can be injected into the casting trough at the top of the fixed column. The cement will be discharged through the discharge hole on the outside of the fixed column. The cement can be discharged between the four-umbrella insulator and the iron cap and between the four-umbrella insulator and the steel foot, so that the cement can reach the designated bonding area. By fixing first and then bonding, the stability of the cement pouring can be guaranteed.

[0023] 4. In addition, due to the obstruction of the first umbrella skirt umbrella surface, the cement overflowing from between the four-umbrella insulator and the iron cap can be intercepted, playing a blocking role, preventing excess cement from overflowing, ensuring the completeness of cement filling, and enhancing the connection strength between the four-umbrella insulator, the iron cap and the cement. At the same time, due to the obstruction of the first umbrella skirt umbrella surface, external dust and impurities can enter between the four-umbrella insulator and the iron cap when the insulator is in use, and at the same time, the contact area between the external air and the cement can be reduced, reducing oxidation and erosion.

[0024] 5. By adding the first shed, the number of overall sheds is increased. Since four sheds are spaced apart and of different sizes, the creepage distance is increased, which can effectively extend the leakage path, thereby improving the insulation level of the insulator and preventing surface flashover.

[0025] 6. When the steel foot is installed, multiple reinforcing ribs can contact the outside of the steel foot, thereby ensuring the stability of the steel foot installation. At the same time, when the multiple reinforcing ribs are mixed with cement, the connection strength between the steel foot and the four-umbrella insulator can be improved. Furthermore, the multiple reinforcing ribs can intercept the cement during cement pouring, slow down the cement flow rate, and make the cement stay at a specified height.

[0026] 7. When cement is filled in the casting trough inside the fixed column, the casting trough can be made solid, thereby improving the structural strength. The whole structure can be connected by pouring cement, and due to the insulating properties of cement, the four-umbrella insulator, iron cap and steel foot are connected without generating any conductive phenomenon.

[0034] The present invention provides Figures 1 to 6 A disc-shaped ceramic insulator shown includes a four-shed insulator 1, an iron cap 3, and a steel leg 6. The outer side of the four-shed insulator 1 is provided with a first shed 7, a second shed 8, a third shed 9, and a fourth shed 10, sequentially arranged from top to bottom. The four sheds, spaced apart and of varying sizes, increase the creepage distance and effectively extend the leakage path (i.e., the current path along the insulator surface), thereby improving the insulation level of the insulator and preventing surface flashover.

[0035] There is a distance between the first umbrella skirt 7, the second umbrella skirt 8, the third umbrella skirt 9 and the fourth umbrella skirt 10. The radius of the first umbrella skirt 7 is larger than the radius of the bottom end of the iron cap 3, and the radii of the second umbrella skirt 8, the fourth umbrella skirt 10, the third umbrella skirt 9 and the first umbrella skirt 7 are arranged from large to small.

[0036] Since the radii of the first umbrella skirt 7, the second umbrella skirt 8, the third umbrella skirt 9 and the fourth umbrella skirt 10 are inconsistent, when it rains, the water flow is not easy to form a vertical water curtain and a conductive path.

[0037] The iron cap 3 is sleeved on the top of the four-shade insulator 1, and the first shed 7 is located below the iron cap 3. The radius of the first shed 7 is smaller than the radius of the second shed 8. A mounting groove 4 is opened on the top of the iron cap 3, and a steel foot 6 is arranged at the bottom end inside the four-shade insulator 1.

[0038] In the actual operation of the present invention, multiple four-umbrella insulators 1 can be connected up and down, and the steel foot 6 of the upper four-umbrella insulator 1 can be installed in the installation groove 4 of the lower four-umbrella insulator 1 to complete the connection.

[0039] In order to solve the problem of bonding the steel foot, iron cap and ceramic umbrella plate with cement, during the bonding process, since it takes a certain amount of time for the cement to solidify itself, if the cement collapses, it is easy to cause the steel foot and iron cap to fall over, resulting in the position of the finished steel foot and iron cap to tilt, affecting the quality of the insulator. If a clamping mechanism is used to protect the steel foot and iron cap vertically, it will increase the production cost.

[0040] Therefore, a fixing column 12 is threadedly installed on the top of the steel foot 6, and the top of the fixing column 12 extends out of the mounting slot 4. The fixing column 12 can be made of insulating material, such as silicone rubber or ceramic material, and a casting groove 18 is opened on the top of the fixing column 12. Two discharge holes 13 are opened on the outside of the fixing column 12 along the height direction. The discharge holes 13 are connected to the inside of the casting groove 18. The upper discharge hole 13 is connected to the four-umbrella insulator 1 and the iron cap 3, and the lower discharge hole 13 is connected to the four-umbrella insulator 1 and the steel foot 6. Cement 11 is poured between the four-umbrella insulator 1 and the iron cap 3 and between the four-umbrella insulator 1 and the steel foot 6.

[0041] An external thread 19 is provided on the outer side of the protruding end of the fixing column 12, and a mounting opening 32 is provided at the bottom end of the steel foot 6. The external thread 19 is threadedly installed inside the mounting opening 32. Through holes 16 are provided on both sides of the iron cap 3, and a first insertion hole 15 is provided on the outer side of the steel foot 6, and a first bolt 2 is installed between them.

[0042] In the actual operation of the present invention, both ends of the fixing column 12 are respectively connected to the iron cap 3 and the steel foot 6 by threaded connection, which is convenient for installation and disassembly, and convenient for subsequent replacement and maintenance.

[0043] When two four-umbrella insulators 1 are connected up and down, the steel leg 6 of one four-umbrella insulator 1 is inserted into the iron cap 3 of the other four-umbrella insulator 1. By inserting the first bolt 2 between the corresponding first jack 15 and the through hole 16, the connection between the iron cap 3 and the steel leg 6 can be completed, thereby improving the structural strength and stability. Since it is connected by the first bolt 2, it is convenient for disassembly at a later time.

[0044] A through hole 17 is formed at the bottom of the mounting groove 4 for the fixing column 12 to pass through, and a threaded opening is formed at the top of the steel foot 6 for the bottom end of the fixing column 12 to threadably engage with.

[0045] Furthermore, when two four-umbrella insulators 1 are connected up and down, the steel foot 6 of the upper four-umbrella insulator 1 can be connected to the fixing column 12 of the lower four-umbrella insulator 1, further improving the connection strength.

[0046] In the actual operation of the present invention, a steel foot 6 can be installed at the bottom end of the four-umbrella insulator 1, an iron cap 3 can be sleeved on the top of the four-umbrella insulator 1, and a fixing column 12 can be threadedly installed between the four-umbrella insulator 1, the iron cap 3 and the steel foot 6 to enhance the strength and stability of the overall structure. At the same time, through the connection of the fixing column 12, the verticality between the four-umbrella insulator 1, the iron cap 3 and the steel foot 6 can be maintained.

[0047] Furthermore, cement can be injected into the casting trough 18 at the top of the fixed column 12, and the cement will be discharged through the discharge hole 13 on the outside of the fixed column 12. The cement can be discharged between the four-umbrella insulator 1 and the iron cap 3 and between the four-umbrella insulator 1 and the steel foot 6, so that the cement can reach the designated bonding area. By fixing first and then bonding, the stability of the cement pouring can be guaranteed.

[0048] In addition, due to the obstruction of the umbrella surface of the first umbrella skirt 7, the cement overflowing from between the four-umbrella insulator 1 and the iron cap 3 can be intercepted, playing a blocking role, preventing excess cement from overflowing, ensuring the completeness of cement filling, and enhancing the connection strength between the four-umbrella insulator 1, the iron cap 3 and the cement. At the same time, due to the obstruction of the umbrella surface of the first umbrella skirt 7, external dust and impurities can enter between the four-umbrella insulator 1 and the iron cap 3 when the insulator is in use.

[0049] A plurality of reinforcing ribs 14 are fixed to the bottom end of the inner part of the four-umbrella insulator 1. One end of the plurality of reinforcing ribs 14 contacts the outer side of the steel foot 6. The reinforcing ribs 14 are elastic and will not block the installation of the steel foot 6. Silicone rubber or other elastic materials can be used to increase the insulation performance.

[0050] In the actual operation of the present invention, the multiple reinforcing ribs 14 can contact the outer side of the steel foot 6 when the steel foot 6 is installed, thereby ensuring the stability of the installation of the steel foot 6. At the same time, the multiple reinforcing ribs 14 can improve the connection strength between the steel foot 6 and the four-umbrella insulator 1 when mixed with cement. Furthermore, the multiple reinforcing ribs 14 can intercept cement during cement pouring, slow down the downward flow of cement, and make the cement stay at a specified height.

[0051] Specifically, the falling speed of the cement can be controlled by setting the density of the reinforcing ribs 14 .

[0052] When cement is filled into the casting groove 18 inside the fixed column 12, the casting groove 18 can be made solid, thereby improving the structural strength. The whole structure can be connected by pouring cement, and due to the insulating property of cement, the four-umbrella insulator 1, the iron cap 3 and the steel foot 6 are connected without generating any conductive phenomenon.

[0053] A gap is left between the first shed 7 and the iron cap 3 to facilitate cement entry and bonding.

[0054] The present invention further discloses a fixing plate, comprising a fixing assembly 5 , which can be installed on a cable to facilitate the connection of the four-umbrella insulator 1 at the top.

[0055] The fixing assembly 5 includes a first chuck 20 and a second chuck 21. The first chuck 20 and the second chuck 21 are cylindrically sleeved on the outside of the cable. The outsides of the first chuck 20 and the second chuck 21 are connected to a fixing plate 22, and a second bolt 23 is provided between the two corresponding fixing plates 22.

[0056] An insulating sleeve 24 is fixed to the inner side of the first chuck 20 and the second chuck 21. A tripod 25 is fixed to the bottom end of the second chuck 21. A third bolt is installed between the tripods 25. A fixing ring 26 is sleeved on the outer side of the third bolt. A connecting column 27 is fixed to the bottom end of the fixing ring 26. A sleeve 28 is slidingly sleeved on the outer side of the connecting column 27. The sleeve 28 is set in a T shape corresponding to the mounting groove 4.

[0057] A second insertion hole 31 corresponding to the through hole 16 is defined at the outer bottom end of the sleeve 28 .

[0058] In the actual operation of the present invention, the first chuck 19 and the second chuck 20 can be engaged with the outside of the cable, and by connecting the second bolt 23, the first chuck 19 and the second chuck 20 can be clamped to the outside of the cable, the sleeve 28 can be installed inside the mounting groove 4 of the iron cap 3, and the second socket 31 on the sleeve 28 and the through hole 16 on the iron cap 3 can be connected by the first bolt 2 to complete the fixed installation.

[0059] A fixing screw 29 is provided on the outside of the sleeve 28 , and a plurality of docking holes 30 are opened on the outside of the connecting column 27 along the height direction. One end of the fixing screw 29 is fitted into the inside of the docking hole 30 .

[0060] Furthermore, the sleeve 28 can be slidably installed on the outside of the connecting column 27. The distance between the sleeve 28 and the connecting column 27 can be changed by sliding, thereby adaptively adjusting the length, which is convenient for actual installation and the required length.
