Description

Technical Field

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

[0002] Suspension insulators are generally made of insulating parts, i.e. porcelain parts, and metal accessories, such as steel legs and iron caps, which are glued together or mechanically clamped. Insulators are widely used in power systems and are generally external insulation, working under atmospheric conditions. Overhead transmission lines, busbars of power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the earth or grounded objects or other conductors with potential differences.

[0003] The existing suspension porcelain insulator has a simple structure, and it is not convenient for users to replace the steel legs during use, thereby reducing the flexibility of the device; at the same time, the porcelain insulator is not adjustable and does not have a certain elastic potential energy. If the high-voltage line is blown by strong winds, the connecting parts between the insulator and the high-voltage line will be directly worn, resulting in damage to the connection between the insulator and the high-voltage line. At the same time, during the inspection process, the porcelain insulator needs to be disassembled to observe whether it can continue to be used. Summary of the invention

[0016] (II) Beneficial effects

[0017] The present invention provides a suspension porcelain insulator, which has the following beneficial effects:

[0018] 1. The present invention arranges a mounting assembly inside the steel cap, wherein an adjustment groove is arranged between two groups of clamping tables, and an adjustment ball head can be placed inside the adjustment groove. Meanwhile, a fixing plate and an elastic plate are arranged outside the connecting rod. The clamping table is bonded to the bottom of the insulating body by an adhesive, and a horn groove is arranged inside the insulating body. Through the horn groove and the adjustment groove, the steel foot can be turned, thereby effectively reducing the damage caused by the overall vibration of the porcelain insulator when encountering strong winds. After the insulator string is formed, when encountering strong winds, a group of porcelain insulators will be deflected, and the porcelain insulators below it will be forced to reset vertically under the action of gravity, that is, the porcelain insulators in the insulator string are both integrated and independent of each other, which effectively enhances its wind resistance.

[0019] 2. After rotating the sealing plug to correspond with one end of the threaded rod and buckling the sealing plug, use a screwdriver to rotate the threaded rod so that the two sets of clamping tables move away from each other, thereby increasing the distance between the two sets of clamping tables, and the adjusting ball head can be placed between the two sets of adjusting grooves. Then, by reversing the threaded rod, the two sets of clamping tables will wrap the adjusting ball head through the adjusting groove, so that the steel foot can be easily disassembled. At the same time, when several sets of porcelain insulators are connected to each other, when the connecting table enters the connecting groove, by pressing the top block, after the connecting table completely enters the adjusting ball head, the top block will press against the alignment groove under the action of the spring, thereby improving the stability of the connecting table. When disassembling, you only need to squeeze the top block through the connecting table and then take out the connecting table through the adapter groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The steel cap 200 is fixedly connected to the upper part of the insulating body 100, and the steel foot 300 is installed inside the steel cap 200, and the bottom of the steel foot 300 passes through the insulating body 100;

[0035] A connecting groove 201 is provided on the top of the steel cap 200, and a mounting groove is provided inside the steel cap 200. A mounting assembly is provided inside the mounting groove. The mounting assembly includes a threaded rod 211 and two sets of clamping platforms 206 arranged opposite to each other. The threaded rod 211 passes through the two sets of clamping platforms 206. A thread is provided in the middle area outside the threaded rod 211. The thread is used to make the two sets of clamping platforms 206 move toward or away from each other at the same time. A guide rod 210 is provided between the two sets of clamping platforms 206. An adjustment groove 213 is provided on the adjacent sides of the two sets of clamping platforms 206.

[0036] The steel foot 300 includes a connecting rod 302, one end of which is fixedly connected to an adjusting ball head 301, and the adjusting ball head 301 is arranged inside an adjusting groove 213 on an adjacent side of the two sets of clamping platforms 206. The other end of the connecting rod 302 is fixedly connected to a connecting platform 304. The outside of the connecting rod 302 is slidably connected to an elastic sheet 305, and the outside of the elastic sheet 305 is fixedly connected to a fixing sheet 303.

[0037] It should be noted that several groups of porcelain insulators can be connected in sequence to form an insulator string, and the number of porcelain insulators in the insulator string shall not exceed 10.

[0038] Furthermore, an adapting groove 202 communicating with the connecting groove 201 is provided on the outside of the steel cap 200 , and a limiting sliding groove 209 is provided inside the steel cap 200 at the bottom of the adapting groove 202 .

[0039] Specifically, the connection platform 304 is inserted into the connection slot 201 through the adaption slot 202 to complete the connection between the porcelain insulators.

[0040] Furthermore, a top block 205 is slidably connected inside the adapter groove 202, a spring 208 which is always in a compressed state is arranged inside the limiting groove 209, a limiting plate 207 is slidably connected inside the limiting groove 209, and the limiting plate 207 is fixedly connected to the top block 205 via a connecting column.

[0041] The spring 208 pushes the top block 205 to move upward, so that the top block 205 can press against the bottom of the connecting platform 304 .

[0042] Furthermore, the steel cap 200 is externally rotatably connected to a rotating sleeve 203 , and a sealing plug 204 is disposed externally of the rotating sleeve 203 .

[0043] It can be understood that the corresponding position of the sealing plug 204 can be adjusted by rotating the rotating sleeve 203 .

[0044] It should be noted that the sealing plug 204 is specifically an elastic sheet, and the sealing plug 204 can be buckled out from the outside of the rotating sleeve 203.

[0045] Furthermore, both ends of the threaded rod 211 are fixedly connected to the limiting ring 212, the threaded rod 211 is rotatably connected to the inside of the steel cap 200, and both ends of the threaded rod 211 are provided with a hexagram groove, and the end of the threaded rod 211 corresponds to the position of the sealing plug 204.

[0046] Among them, after rotating the sealing plug 204 to correspond with one end of the threaded rod 211, the sealing plug 204 is buckled out, and the threaded rod 211 can be rotated using a screwdriver to make the two groups of clamping platforms 206 move away from each other, thereby increasing the distance between the two groups of clamping platforms 206, and the adjusting ball head 301 can be placed between the two groups of adjusting grooves 213. Then, by reversing the threaded rod 211, the two groups of clamping platforms 206 will wrap the adjusting ball head 301 through the adjusting groove 213.

[0047] In other embodiments, a spring may be provided on the side of the two groups of clamping platforms 206 facing away from each other, and the two ends of the spring are respectively fixedly connected to the outside of the clamping platform 206 and the inner wall of the installation groove, so that the spring will squeeze the outside of the clamping platform 206.

[0048] Furthermore, guide rods 210 are provided on the opposite sides of the two groups of clamping platforms 206 , and the guide rods 210 are used to guide the two groups of clamping platforms 206 when they move toward or away from each other.

[0049] It can be understood that one end of the guide rod 210 is fixedly connected to any one group of clamping platforms 206, and a guide groove is provided at a corresponding position of the other group of clamping platforms 206, and the guide rod 210 is slidably connected inside the guide groove.

[0050] Furthermore, the fixing sheet 303 is fixedly connected to the bottom of the insulating body 100 , a speaker groove is provided inside the insulating body 100 , and the connecting rod 302 passes through the speaker groove.

[0051] It should be noted that the minimum diameter of the horn groove is matched with the diameter of the adjustment ball head 301 .

[0052] After the two sets of clamping platforms 206 are separated, the steel foot 300 can be taken out through the speaker slot, and the steel foot 300 can be quickly replaced by rotating the threaded rod 211 with a screwdriver.

[0053] Furthermore, the steel foot 300 can be turned by means of the horn groove and the adjustment groove 213, thereby effectively reducing the damage caused by the overall vibration of the porcelain insulator when encountering strong winds. After the insulator string is formed, when encountering strong winds, a group of porcelain insulators will be deflected, and the porcelain insulators below it will be forced to return vertically under the action of gravity, that is, the porcelain insulators in the insulator string are both integrated and independent of each other, which effectively enhances its wind resistance.

[0054] It can be understood that the fixing sheet 303 is bonded to the bottom of the insulating body 100 by adhesive.

[0055] It should be noted that the maximum turning angle of the steel foot 300 is 15°.

[0056] Furthermore, an alignment groove is provided at the bottom of the connecting platform 304, the depth of the alignment groove is less than 1 mm, and the top block 205 is adapted to the size of the alignment groove.

[0057] Specifically, when the connecting platform 304 enters the connecting groove 201 , by pressing the top block 205 , after the connecting platform 304 completely enters the adjusting ball head 301 , the top block 205 will press against the alignment groove under the action of the spring 208 , thereby improving the stability of the connecting platform 304 .

[0058] When disassembling, the connecting platform 304 can be taken out by squeezing the top block 205 through the connecting platform 304 and then passing through the adapting groove 202 .

[0059] The suspension porcelain insulator provided by the present invention is provided with a mounting assembly inside a steel cap 200, wherein an adjustment groove 213 is provided between two groups of clamping platforms 206, an adjustment ball head 301 can be placed inside the adjustment groove 213, and a fixing sheet 303 and an elastic sheet 305 are provided outside a connecting rod 302, the clamping platform 206 is bonded to the bottom of an insulating body 100 by an adhesive, and a horn groove is provided inside the insulating body 100, and the steel leg 300 can be turned through the horn groove and the adjustment groove 213, so that the porcelain insulator can be effectively reduced in the event of overall vibration and thus damage caused when encountering strong winds. After an insulator string is formed, when encountering strong winds, a group of porcelain insulators is deflected, and the porcelain insulators below it are forced to be vertically reset under the action of gravity, that is, the porcelain insulators in the insulator string are both integrated and independent of each other, and their wind resistance is effectively enhanced.

[0060] Secondly, after rotating the sealing plug 204 to correspond to one end of the threaded rod 211, the sealing plug 204 is buckled out, and the threaded rod 211 can be rotated with a screwdriver to make the two groups of clamping platforms 206 move away from each other, thereby increasing the distance between the two groups of clamping platforms 206, and the adjusting ball head 301 can be placed between the two groups of adjusting grooves 213. Then, by reversing the threaded rod 211, the two groups of clamping platforms 206 will wrap the adjusting ball head 301 through the adjusting groove 213, so that the steel foot 300 can be easily disassembled. At the same time, when several groups of porcelain insulators are connected to each other, when the connecting platform 304 enters the connecting groove 201, by pressing the top block 205, after the connecting platform 304 completely enters the adjusting ball head 301, the top block 205 will resist the alignment groove under the action of the spring 208, thereby improving the stability of the connecting platform 304. When disassembling, it is only necessary to squeeze the top block 205 through the connecting platform 304 and then take out the connecting platform 304 through the adapter groove 202.

[0061] 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.
