Description

Technical Field

[0001] The invention relates to the technical field of insulators, in particular to a novel high-strength porcelain insulator. Background Art

[0002] Insulators are devices used to support transmission cables. Insulators are used to support cables to prevent them from dragging on the ground and causing leakage.

[0003] Most of the existing insulators are porcelain insulators, which have strong supporting strength and low manufacturing cost, but have a short service life and need to be replaced. The existing patent CN217239171U discloses a hollow porcelain insulator that is easy to install and replace, including a pole bracket, a mounting plate and a limiter. The bottom end of the pole bracket is provided with a fixing member, and the bottom end of the fixing member is connected to a limiter rod. The mounting plate is arranged at the bottom end of the pole bracket, and an installation cavity is provided on the inner wall of the mounting plate. A telescopic spring for driving the limiter to telescopically move is installed inside the mounting cavity. One end of the limiter is located on the inner wall of the limiter rod and a limiter groove is provided. The hollow porcelain insulator is easy to install and replace, easy to load and unload, and has a lightning protection function.

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figures 1 to 8 , the present invention provides a technical solution:

[0031] Embodiment 1: A new type of high-strength porcelain insulator comprises a right-angle side frame 1 and an insulating column 6. One side of the right-angle side frame 1 is installed on a high-altitude transmission frame. A lower stud 2 is provided on the lower end plate of the right-angle side frame 1. An upper plug rod 3 is provided on the lower stud 2. The lower end of the insulating column 6 is provided with a lower mounting groove 19 for plugging and mounting with the upper plug rod 3.

[0032] By providing the lower installation groove 19 and cooperating with the upper insertion rod 3, the insertion and limiting installation of the lower end of the insulating column 6 is achieved.

[0033] An upper mounting piece 8 for supporting the power transmission cable 12 is installed at the upper end of the insulating column 6, an elastic component is pressed between the lower mounting groove 19 and the upper plug rod 3, and a limiting beam 4 and an upper beam 5 located at the upper end of the upper mounting piece 8 are arranged on the right-angle side frame 1. A lower clamp 10 for cooperating with the upper mounting piece 8 to fix and clamp the power transmission cable 12 is rotatably installed on the limiting beam 4.

[0034] By arranging the lower clamp 10 and the upper mounting member 8 to cooperate, the transmission cable 12 can be supported and clamped in a limited position.

[0035] The upper mounting member 8 is provided with a lower plug-in block 27 which cooperates with the insulating column 6, and a hook groove 28 is provided on the lower plug-in block 27. The insulating column 6 is laterally plugged with a plug rod assembly 11 which cooperates with the hook groove 28. After the upper mounting member 8 is flipped and rotated along the limiting beam 4, the hook groove 28 on the lower plug-in block 27 can be snapped onto the upper beam 5.

[0036] By setting the lower plug block 27 with the hook groove 28 and cooperating with the plug rod assembly 11, the upper mounting member 8 is fixedly installed on the insulating column 6, and the temporary support of the transmission cable 12 is achieved by utilizing the cooperation between the hook groove 28 and the upper crossbeam 5.

[0037] Working principle: First, during installation, the insulating column 6 is plugged into the upper plug rod 3, and the upper mounting member 8 is plugged into the upper end of the insulating column 6. The plug rod assembly 11 is used for lateral insertion to press it onto the hook groove 8, so that the upper mounting member 8 is fixedly installed while the plug rod assembly 11 is stored in the insulating column 6 to avoid environmental erosion. During replacement, the plug rod assembly 11 is pulled out, and the elastic component is used to make the insulating column 6 drop along the upper plug rod 3, thereby exposing the lower plug block 27. The lower plug block 27 is rotated along the limiting beam 4 to make the hook groove 28 reversely clamped on the upper beam 5 to achieve temporary support for the transmission cable 12. Then the insulating column 6 is pulled out upward for replacement. After replacement, the insulating column 6 is re-fixed and installed under the reset elastic force of the elastic component and the reset rotation of the lower plug block 27.

[0038] Example 2: On the basis of Example 1, in order to further improve the installation strength and stability of the lower end of the insulating column 6, a square hole 16 is provided at the upper end of the insulating column 6, and a transverse slot 7 vertically connected to the square hole 16 is provided on the arc-shaped outer wall of the upper end of the insulating column 6. The lower plug-in block 27 is plugged and installed along the square hole 16, and the hook groove 28 on the lower plug-in block 27 corresponds to the transverse slot 7. A driving column 22 with an outer diameter equal to the inner diameter of the hook groove 28 is provided on the plug-in rod assembly 11. After the plug-in rod assembly 11 is plugged along the transverse slot 7, the driving column 22 cooperates with the hook groove 28 for plugging.

[0039] By setting the transverse slot 7 and the square hole 16, the lower plug block 27 and the plug rod assembly 11 are installed with limited insertion, and the lower plug block 27 is pressed downward by the cooperation between the driving column 22 and the hook groove 28 to achieve the purpose of fixing the upper installation block 8.

[0040] A support screw ring 14 is rotatably installed on the lower stud 2, and an insulating gasket 13 is provided on the upper end of the support screw ring 14. The upper end of the insulating gasket 13 fits the lower end surface of the insulating column 6. An upper clamp 9 is provided on the upper end of the upper mounting member 8. The upper clamp 9 is fixedly matched with the lower clamp 10 and clamps the power transmission cable 12. The upper end of the lower clamp 10 is provided with a ring 35 rotatably sleeved on the limiting beam 4.

[0041] By setting the cooperation between the supporting screw ring 14 and the lower stud 2, the raising and lowering of the insulating column 6 can be adjusted by threaded rotation. The raising and lowering of the insulating column 6 can be controlled by the threaded rotation of the supporting screw ring 14 on the lower stud 2, thereby achieving precise adjustment of the height position of the insulating column 6, ensuring installation accuracy and stability.

[0042] Example 3: On the basis of Example 2, in order to prevent the metal spring from being affected by the electromagnetic force of the power transmission cable 12, the elastic component includes a folding tube 15, an elastic pull rod 20 and an elastic sheet ring 21. The folding tube 15 is located between the lower mounting groove 19 and the upper insertion rod 3. The inner sides of adjacent annular folding plates of the folding tube 15 are connected by elastic sheet rings 21. The elastic sheet ring 21 is supported between adjacent annular folding plates. The elastic sheet ring 21 is an insulating plastic part. The inner circle of the elastic sheet ring 21 is provided with multiple groups of elastic pull rods 20 distributed in a circular array.

[0043] By providing an insulating elastic member consisting of a folding tube 15 and an elastic sheet ring 21, elastic support is achieved while avoiding electromagnetic influence. The vertical support of the elastic sheet ring 21 is utilized to ensure the extension of the folding tube 15. When subjected to the upward supporting force of the supporting screw ring 14, the elastic sheet ring 21 is deformed elastically by pressure to achieve the contraction of the folding tube 15. When the supporting screw ring 14 descends, the restoring elastic force of the elastic pull rod 20 and the elastic sheet ring 21 enables the folding tube 15 to be restored and extended.

[0044] Example 4: On the basis of Example 3, in order to further improve the installation strength of the insulating column 6, a pair of extension arms 17 are provided on the upper plug rod 3, and a pair of vertical grooves connected to the horizontal slot 7 are provided on the lower installation groove 19. The extension arm 17 is inserted along the vertical groove, and the upper end of the extension arm 17 is provided with a through hole 18 corresponding to the horizontal slot 7. A pair of support columns 25 are provided on the plug rod assembly 11, and the outer diameter of the support column 25 is smaller than the outer diameter of the driving column 22. The pair of support columns 25 are respectively inserted in the through holes 18 on the symmetrically distributed extension arms 17.

[0045] By setting the extension arm 17, the upper plug rod 3 and the plug rod assembly 11 are matched and plugged in, so that the support column 25 and the through hole 18 are plugged in to achieve the purpose of limiting the height of the insulating column 6. As the support screw ring 14 is driven upward, the through hole 18 is opposite to the horizontal slot 7, and the support column 25 is used to limit the extension arm 17 to form a vertical plug-in fixation. At this time, even if the support screw ring 14 falls off and loses its supporting force, the insulating column 6 can still maintain the position height of supporting the transmission cable 12.

[0046] An arc groove extending inward is provided on one side of the notch position of the hook groove 28, and a telescopic arc plate 29 is slidably installed in the arc groove. One end of the telescopic arc plate 29 extends to the outside of the arc groove and is provided with a rotating seat. A rotating clamping plate 30 is rotatably installed on the rotating seat at the end of the telescopic arc plate 29, and a block for limiting the rotation angle of the rotating clamping plate 30 is provided on the rotating seat. A lower opening groove 24 that cooperates with the rotating clamping plate 30 for sliding insertion is provided on the arc outer wall of the driving column 22, and the side walls of the rotating clamping plate 30 fit the inner walls of the lower opening groove 24 on both sides.

[0047] By setting the lower opening groove 24 to cooperate with the rotation of the rotating card plate 30, the telescopic arc plate 29 is driven to rotate. In the actual working process, before the lower plug block 27 is plugged in, the rotating card plate 30 is flipped upward. After the insertion rod assembly 11 is plugged in, the outer diameter of the front support column 25 is smaller than the rotating card plate 30, so it directly passes over, and the lower opening groove 24 on the driving column 22 is just plugged in with the rotating card plate 30, and then the insertion rod assembly 11 is rotated, and the rotation of the insertion rod assembly 11 is used to drive the telescopic arc plate 29 to extend, thereby closing the gap, increasing the contact area between the driving column 22 and the hook groove 28, and preventing the upper mounting part 8 from shifting left and right and causing the driving column 22 to fall off along the gap.

[0048] A limit plate 23 is provided at the other end of the insertion rod assembly 11, and an expansion semi-ring 33 is provided at the lower end of the limit plate 23. The outer port of the transverse slot 7 is set to an outer contour that matches the limit plate 23 and the expansion semi-ring 33. The inner diameter of the inner side of the port of the transverse slot 7 is set to be the same as the outer diameter of the expansion semi-ring 33. A spring 26 is provided at one end of the insertion rod assembly 11, and the spring 26 is abutted between the end of the insertion rod assembly 11 and the inner wall of the transverse slot 7. The inner wall of the lower end of the square hole 16 is provided with an arc groove that fits the arc-shaped outer wall of the telescopic arc plate 29. A plurality of groups of protrusions 34 distributed in a circular array are provided on the expansion semi-ring 33, and a plurality of groups of hole grooves are provided on the inner side of the port of the transverse slot 7. The positions of the hole grooves are displaced in a circle with the protrusions 34.

[0049] During the installation of the insertion rod assembly 11, the limit plate 23 is extended to the inner side of the port of the transverse slot 7 through plugging. Through the rotation of the insertion rod assembly 11, the expansion half ring 33 is misaligned with the outer contour of the port of the transverse slot 7. Then, under the restoring elastic force of the spring 26, the expansion half ring 33 is pressed onto the inner wall of the port of the transverse slot 7, thereby achieving the purpose of fixing the insertion rod assembly 11 and preventing the insertion rod assembly 11 from falling off. By setting the protrusion 34 to cooperate with the hole groove, after rotation, the protrusion 34 on the expansion half ring 33 corresponds to the hole groove, and under the restoring elastic force of the spring 26, the protrusion 34 is plugged into the hole groove, thereby achieving the purpose of adjusting the rotation angle of the insertion rod assembly 11 and preventing the insertion rod assembly 11 from falling off due to self-rotation.

[0050] During disassembly, it is necessary to first drive the rod assembly 11 inward to squeeze the spring 26 so that the protrusion 34 is separated from the hole groove, and then rotate the rod assembly 11 so that the expanded diameter half ring 33 is adapted to the outer contour of the port of the transverse slot 7, and then pull out the rod assembly 11 to achieve the disassembly of the insulating column 6.

[0051] A slot is provided at one end of the notch of the hook slot 28 away from the telescopic arc plate 29, and the slot can be matched with the end of the rotating card plate 30. Elastic pins 32 are symmetrically provided at both ends of the inner side of the slot. The gap width between a pair of elastic pins 32 is smaller than the width of the rotating card plate 30. A through hole 31 is provided at the end of the rotating card plate 30, and the through hole 31 can be matched with the elastic pin 32. The elastic pin 32 is elastically plugged into the inner wall of the slot. The notch of the hook slot 28 is closed by the cooperation between the rotating card plate 30 and the elastic plug 32.

[0052] After the lower plug block 27 rotates in the opposite direction so that the hook groove 28 is clamped on the upper cross beam 5 along the notch, the telescopic arc plate 29 is manually pulled and slid to extend toward the position of the clamping groove, and then the rotating clamping plate 30 is driven to rotate to a position that cooperates with the clamping groove, and the elastic pin rod 32 is pulled out in both directions so that the end of the rotating clamping plate 30 is clamped in the clamping groove, and the elastic pin rod 32 is loosened so that it is inserted into the through hole 31, thereby achieving the purpose of closing the hook groove 28 and ensuring the installation strength of the temporary support.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
