Description

Technical Field

[0001] This invention relates to the field of ceramic insulator technology, and more particularly to a sealed ceramic insulator with a wiring assembly. Background Technology

[0002] Sealed ceramic insulators are a key piece of equipment used in power systems. Their core function is to provide mechanical support and electrical insulation in high-voltage environments, ensuring the safe operation of power equipment.

[0003] The sealed ceramic insulator has a U-shaped groove at the top, which is used to directly place the conductor. The bottom of the sealed ceramic insulator is equipped with a threaded rod and a nut for fixing the sealed ceramic insulator to the pole support.

[0004] However, in actual operation, due to the limited overlap of the sealed ceramic insulator and the threaded rod connection, the stress on the threaded rod connection is concentrated under wind sway, making it prone to damage. Under wind, the conductor swings back and forth in the U-shaped trough, and the conductor is covered with ice, which causes friction and stress concentration, making the conductor prone to breakage. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the prior art by proposing a sealed ceramic insulator with wiring components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sealed ceramic insulator with wiring components includes a ceramic insulator, a U-shaped cable groove, a mounting rod, a first spring, a pressure plate, and a rotating plate. The U-shaped cable groove is formed and machined on the upper end of the ceramic insulator. The mounting rod is fixed inside the ceramic insulator, with its upper end located at the bottom end of the U-shaped cable groove. The lower end of the mounting rod is detachably mounted on a pole support. Two rotating plates are symmetrically arranged on both sides of the upper end of the U-shaped cable groove. The pressure plate is located on the upper end of the mounting rod, and the first spring is located on the lower end of the pressure plate. When the pressure plate moves vertically downward or upward relative to the mounting rod, the pressure plate drives the rotating plates on both sides to rotate synchronously towards or away from each other.

[0007] Preferably, a rotating head is fixedly provided in the middle of the side of the rotating plate, and support plates are symmetrically arranged on both sides of the rotating head. A rotating shaft is fixedly provided inside the rotating head, and the outer ends of the rotating shaft are rotatably connected to the inner upper end of the corresponding support plate through bearings. The bottom end of the support plate is fixedly provided on the upper end face of the U-shaped groove.

[0008] Preferably, the upper end of the mounting rod has a circular groove inside, the bottom end of the pressure plate has a lifting column fixed in the middle, the bottom end of the lifting column has a sliding groove opening upward, the bottom surface of the circular groove has a guide column fixed in the middle, the sliding groove is sleeved on the outside of the guide column, and the outside of the guide column is also sleeved with a first spring. The first spring is tightly connected between the bottom end of the lifting column and the bottom surface of the circular groove. When the lifting column moves vertically relative to the other side in the circular groove, it drives the rotating plates on both sides to rotate synchronously away from each other or towards each other. The pressure plate is located in the U-shaped groove.

[0009] Preferably, a first positioning post is fixedly provided at the lower center of the end face of the rotating plate, and second positioning posts are symmetrically fixed on both sides of the upper end face of the U-shaped groove. A second spring is sleeved and fixed between the outer sides of the first positioning post and the corresponding second positioning post. Circuit holes are symmetrically opened inside both sides of the U-shaped groove. The two ends of the circuit holes extend and penetrate the interior of the corresponding second positioning post and the interior of the side wall of the mounting rod. A pull rope is slidably connected through the circuit hole. One end of the pull rope is fixed to the lower end of the outer wall of the lifting post, and the other end of the pull rope passes through the interior of the corresponding second spring and is fixed to the end of the first positioning post. There is a gap between the outer wall of the lifting post and the inner wall of the circular groove.

[0010] Preferably, when the rotating plates on both sides are in a relatively open state, they do not interfere with the placement of the wire, and when the rotating plates on both sides are in a relatively closed state, they clamp and limit the wire on both sides.

[0011] Preferably, anti-slip pads are attached to the upper surface of the pressure plate and the contact surface between the rotating plate and the wire.

[0012] Preferably, the pull rope is made of an insulating, corrosion-resistant material with a certain strength.

[0013] Preferably, the horizontal length of the rotating plate matches the horizontal length of the U-shaped groove, and the gap between the two rotating plates decreases and they do not interfere with each other when they are closed together.

[0014] Preferably, a limiting plate is coaxially fixed to the outer periphery of the lower end of the mounting rod, a gasket is provided at the lower end of the limiting plate, the gasket is sleeved on the outside of the mounting rod, and a nut is externally threaded to the threaded section at the lower end of the mounting rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: by fixing the mounting rod through the inside of the ceramic insulator, the mechanical load on the ceramic insulator is evenly distributed, avoiding the occurrence of cracks due to stress concentration at the connection between the ceramic insulator and the mounting rod, thus extending the service life of the ceramic insulator; the conductor is pressed against the upper end of the pressure plate by its own weight, and the pressure plate moves downward in a straight line in coordination with the first spring to achieve balance, while driving the rotating plates on both sides to rotate synchronously in opposite directions to clamp and limit the conductor on both sides. Under wind-driven swaying, the rotating plates on both sides still limit the conductor's movement, resulting in a smaller amplitude of conductor sway compared to the original design. This reduces friction on the conductor within the U-shaped groove, preventing severe wear on the outer casing caused by friction during the conductor's reciprocating swaying within the groove, as was the case in the original design. When the conductor surface is covered with ice, the overall weight of the conductor increases, causing the pressure plate to move downwards and reach a new equilibrium. Simultaneously, the rotating plates on both sides rotate in opposite directions, clamping the conductor and keeping it in a limited position. The buffering effect of the first spring prevents increased stress at the contact point after the conductor becomes covered with ice, thus avoiding damage to the conductor and ceramic insulator caused by the original design. When a section of the conductor needs repair, the conductor can be simply removed from the top of the pressure plate. At this time, the pressure plate moves upwards to reset under the restoring deformation of the first spring, and the rotating plates on both sides rotate synchronously to reset under the drive. The operation is simple and convenient for maintenance. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] The terms used in this invention, such as "upper," "lower," "left," "right," "middle," and "one," are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0020] like Figure 1-8 As shown, this embodiment of the invention provides a sealed ceramic insulator with wiring components, including a ceramic insulator 100, a U-shaped groove 101, a mounting rod 200, a first spring 304, a pressure plate 305, and a rotating plate 403. The U-shaped groove 101 is formed and machined on the upper end of the ceramic insulator 100. The mounting rod 200 is fixedly installed inside the ceramic insulator 100, with its upper end located at the bottom end of the U-shaped groove 101. The lower end of the mounting rod 200 is detachably installed on a pole support. Two rotating plates 403 are symmetrically arranged on both sides of the upper end of the U-shaped groove 101. The pressure plate 305 is arranged on the upper end of the mounting rod 205, and the first spring 304 is arranged on the lower end of the pressure plate 305. When the pressure plate 305 moves vertically downward or upward relative to the mounting rod 200, the pressure plate 305 drives the rotating plates 403 on both sides to rotate synchronously towards or away from each other.

[0021] In this embodiment, during line erection, the lower end of the mounting rod 200 is installed on the pole support, thus fixing the position of the ceramic insulator 100. Then, the conductor is laid in the U-shaped cable trough 101. During the laying process, the conductor is pressed against the upper end of the pressure plate 305 by its own weight. The pressure plate 305, due to the downward pressure, moves vertically downward relative to the mounting rod 200, compressing the first spring 304. Simultaneously, the rotating plates 403 on both sides are driven to rotate synchronously in opposite directions. When the pressure plate 305 reaches equilibrium under the reverse thrust of the first spring 304 and stops moving downward, the rotating plates 403 on both sides... 03. The conductor is clamped and limited on both sides, thus limiting the position of the conductor within the U-shaped trough 101. During operation, the ceramic insulator 100 needs to withstand mechanical loads such as conductor weight and wind swaying, and stress concentration is prone to occur at the U-shaped trough 101. The mounting rod 200 is fixed inside the ceramic insulator 100 to distribute the mechanical load evenly, preventing breakage due to stress concentration at the connection between the ceramic insulator 100 and the mounting rod 200, and extending the service life of the ceramic insulator 100. Under wind swaying, the conductor would swing back and forth under the original design. However, in this device, since the overall weight of the conductor remains unchanged when it swings, that is, the compressive force on the pressure plate 305 remains unchanged, meaning the vertical position of the pressure plate 305 remains unchanged. This keeps the positions of the rotating plates 403 on both sides unchanged and still limits the conductor on both sides. Consequently, the amplitude of the conductor's swaying under wind force is smaller than in the original design, reducing the friction experienced by the conductor within the U-shaped groove 101. This avoids the severe wear of the outer shell caused by friction due to the conductor's reciprocating swaying within the U-shaped groove 101, as was the case in the original design. When the conductor surface is covered with ice, the overall weight of the conductor increases, causing the downward force on the pressure plate 305 to increase. The pressure plate 305 will then... The conductor moves downward and reaches a new equilibrium. At the same time, the rotating plates 403 on both sides are driven to rotate in opposite directions and clamp the conductor on both sides, so that the conductor is still in a limited state. The buffer of the first spring 304 avoids the increase of stress at the contact position after the conductor is covered with ice in the original design. The conductor and ceramic insulator 100 are prone to damage under wind swing. When a problem occurs in a section of the conductor and needs to be repaired, the conductor can be directly removed from the top of the pressure plate 305. At this time, the pressure plate 305 moves upward and resets under the push of the first spring 304 to recover its deformation. At the same time, the rotating plates 403 on both sides are driven to rotate outward and reset synchronously. The operation is simple and easy to repair. The mounting rod 200 is fixed inside the ceramic insulator 100, so that the mechanical load on the ceramic insulator 100 is evenly distributed, avoiding the occurrence of cracks due to stress concentration at the connection between the ceramic insulator 100 and the mounting rod 200, and extending the service life of the ceramic insulator 100. The conductor is pressed against the upper end of the pressure plate 305 by its own weight. The pressure plate 305 moves downward in a straight line and cooperates with the first spring 304 to achieve balance. At the same time, it drives the rotating plates 403 on both sides to rotate synchronously in opposite directions to clamp and limit the conductor on both sides. Under wind swaying, the rotating plates 403 on both sides still limit the conductor on both sides, making the conductor swaying amplitude smaller than in the original design. This reduces the friction experienced by the conductor within the U-shaped groove 101, avoiding the severe wear of the outer shell caused by friction due to the conductor's reciprocating swaying within the U-shaped groove 101 in the original design. When the conductor surface is covered with ice, the overall weight of the conductor increases, and the pressure plate 305 moves downward to reach a new equilibrium. At the same time, the rotating plates 403 on both sides rotate in opposite directions to clamp the conductor on both sides, keeping the conductor in a limited state. The buffering effect of the first spring 304 prevents the increased stress at the contact point after the conductor is covered with ice, as well as the damage to the conductor and ceramic insulator 100 caused by wind swaying, which was present in the original design. When a problem occurs in a section of the conductor and needs maintenance, the conductor can be directly removed from the top of the pressure plate 305. At this time, the pressure plate 305 moves upward to reset under the push of the first spring 304's recovery deformation. Simultaneously, the rotating plates 403 on both sides rotate synchronously to reset under the drive. The operation is simple and convenient for maintenance.

[0022] like Figure 1 and Figure 6 As shown, optionally, a rotating head 402 is fixedly provided in the middle of the side of the rotating plate 403, and support plates 400 are symmetrically arranged on both sides of the rotating head 402. A rotating shaft 401 is fixedly provided inside the rotating head 402. The outer ends of the rotating shaft 401 are rotatably connected to the upper end of the corresponding support plate 400 through bearings. The bottom end of the support plate 400 is fixedly provided on the upper end face of the U-shaped groove 101.

[0023] In this embodiment, the rotating plate 403 can be rotated relative to the U-shaped wire groove 101 by the rotating shaft 401, so that the rotating plates 403 on both sides can clamp and limit the wires on both sides of the U-shaped wire groove 101 by rotation, so as to prevent the wires from swinging left and right relative to each other in the U-shaped wire groove 101 under wind force, reduce friction, and protect the wire shell.

[0024] like Figure 7 and Figure 8As shown, optionally, a circular groove 300 is provided inside the upper end of the mounting rod 200, a lifting column 301 is fixedly provided at the middle of the bottom end of the pressure plate 305, a sliding groove 302 is provided upward at the middle of the bottom end of the lifting column 301, a guide column 303 is fixedly provided at the middle of the bottom surface of the circular groove 300, the sliding groove 302 is sleeved on the outside of the guide column 303, and a first spring 304 is also sleeved on the outside of the guide column 303. The first spring 304 is fastened between the bottom end of the lifting column 301 and the bottom surface of the circular groove 300. When the lifting column 301 moves vertically relative to the circular groove 300, it drives the rotating plates 403 on both sides to move synchronously away from each other or towards each other. The pressure plate 305 is located in the U-shaped groove 101.

[0025] In this embodiment, since the slide groove 302 is fitted and slides on the outside of the guide post 303, and the first spring 304 is connected between the bottom end of the lifting post 301 and the bottom surface of the circular groove 300, the lifting post 301 can be vertically raised and lowered relative to the inside of the circular groove 300. When the wire is placed on the upper end of the pressure plate 305 in the U-shaped wire groove 101, the pressure plate 305 is squeezed, which will drive the lifting post 301 to move vertically downward and compress the first spring 304. The first spring 304 generates a reverse force due to deformation to support the pressure plate 305. After reaching equilibrium, the vertical position of the wire is adjusted. The conductor remains stationary, and at this time, the rotating plates 403 on both sides rotate in opposite directions to limit the conductor on both sides. When the conductor is covered with ice, the overall weight of the conductor increases, which increases the downward force on the pressure plate 305. The pressure plate 305 will move downward and reach a new equilibrium. At the same time, the rotating plates 403 on both sides continue to rotate in opposite directions to clamp the conductor on both sides, so that the conductor is still in a limited state. When the conductor is removed from the top of the pressure plate 305, the pressure plate 305 moves upward and resets under the push of the first spring 304 to restore its deformation. At the same time, the rotating plates 403 on both sides rotate away from the conductor, making the conductor easier to maintain.

[0026] like Figure 4-8 As shown, optionally, a first positioning post 500 is fixedly provided at the lower center of the end face of the rotating plate 403, and second positioning posts 501 are symmetrically fixed on both sides of the upper end face of the U-shaped wire groove 101. A second spring 502 is sleeved and fixed between the outer side of the first positioning post 500 and the corresponding second positioning post 501. A wire hole 503 is symmetrically opened inside both sides of the U-shaped wire groove 101. The two ends of the wire hole 503 extend and penetrate the interior of the corresponding second positioning post 501 and the interior of the side wall of the mounting rod 200. A pull rope 504 is slidably connected through the wire hole 503. One end of the pull rope 504 is fixed to the lower end of the outer wall of the lifting column 301, and the other end of the pull rope 504 passes through the interior of the corresponding second spring 502 and is fixed to the end of the first positioning post 500. There is a gap between the outer wall of the lifting column 301 and the inner wall of the circular groove 300.

[0027] In this embodiment, when the lifting column 301 moves vertically downwards within the circular groove 300, it stretches the pull ropes 504 on both sides. The ends of the pull ropes 504 away from the lifting column 301 pull the rotating plates 403 on both sides to rotate synchronously in opposite directions, simultaneously compressing the second springs 502 on both sides, causing the second springs 502 to store elastic potential energy. When the lifting column 301 moves vertically upwards within the circular groove 300, the second springs 502 on both sides release the stored elastic potential energy. This allows the rotating plates 403 on both sides to rotate synchronously and separately, while the pull ropes 504 on both sides return to their original tension. This enables the rotating plates 403 on both sides to rotate synchronously or separately through the vertical lifting and lowering of the pressure plate 305. The structure is reasonably distributed and does not affect the placement and removal of wires into the U-shaped wire groove 101. There is a gap between the outer wall of the lifting column 301 and the inner wall of the circular groove 300 to ensure that there is room for operation when the pull rope 504 is stretched, moved or released, while ensuring that the lifting column 301 can stably lift and lower vertically within the circular groove 300.

[0028] like Figure 7 and Figure 8 As shown, optionally, when the two rotating plates 403 are in a relatively open state, they do not interfere with the placement of the wire, and when the two rotating plates 403 are in a relatively closed state, they clamp and limit the wire on both sides.

[0029] In this embodiment, when the two rotating plates 403 are in a relatively open state, they do not interfere with the placement of the wire, so as to ensure that the wire is smoothly placed on the upper end of the pressure plate 305. When the two rotating plates 403 are in a relatively closed state, they clamp and limit the wire on both sides, so as to ensure that the wire is limited as a whole, thereby reducing the swing amplitude, reducing relative wear, extending service life, and ensuring structural rationality.

[0030] like Figure 8 As shown, optionally, anti-slip pads are attached to the upper surface of the pressure plate 305 and the contact surface between the rotating plate 403 and the wire.

[0031] In this embodiment, anti-slip pads are attached to the upper surface of the pressure plate 305 and the contact surface between the rotating plate 403 and the wire to improve the clamping stability of the wire and reduce relative sliding, i.e., reduce relative wear.

[0032] like Figure 5 As shown, optionally, the pull rope 504 is made of an insulating, corrosion-resistant material with a certain strength.

[0033] In this embodiment, the pull rope 504 is made of insulating, corrosion-resistant and strong materials to ensure that the pull rope 504 can be used for a long time in outdoor conditions.

[0034] like Figure 1As shown, optionally, the horizontal length of the rotating plate 403 matches the horizontal length of the U-shaped groove 101, and the gap between the two rotating plates 403 becomes smaller and they do not interfere with each other when they are retracted.

[0035] In this embodiment, by matching the horizontal length of the rotating plate 403 with the horizontal length of the U-shaped cable trough 101, and by reducing the gap between the two rotating plates 403 when they retract and not interfering with each other, it is ensured that when the two rotating plates 403 retract, they not only limit the wires but also block the upper end of the U-shaped cable trough 101, thereby reducing the amount of ice falling into the U-shaped cable trough 101.

[0036] like Figure 1 As shown, optionally, a limiting plate 201 is coaxially fixed to the outer periphery of the lower end of the mounting rod 200, a gasket 202 is provided at the lower end of the limiting plate 201, the gasket 202 is sleeved on the outside of the mounting rod 200, and a nut 203 is externally threaded to the threaded section at the lower end of the mounting rod 200.

[0037] In this embodiment, the mounting rod 200 is inserted into the hole opened on the pole bracket, and then the nut 203 is rotated and tightened on the threaded section at the lower end of the mounting rod 200 from the bottom end of the pole bracket to fix the position of the mounting rod 200, that is, to fix the position of the ceramic insulator 100. Since this is the prior art, it will not be described in detail here.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
