Description

Technical Field

[0001] The utility model relates to the technical field of porcelain insulators, in particular to a porcelain insulator provided with a tightening wire component. Background Art

[0002] Porcelain insulators are important insulating components that play a critical role in overhead transmission lines. Their primary purpose is to support and secure busbars and live conductors, ensuring adequate distance and insulation between live conductors or between conductors and the ground.

[0003] Generally, power lines and porcelain insulators need to be bound together. The basic binding structure relies on metal wires such as aluminum wire or iron wire to wrap and fix them. Although this method of tightening the wires is low-cost and easy to operate, the metal wires are prone to rust and corrosion under the influence of natural factors such as sun and rain for a long time, resulting in premature wear and tear of the metal wires and their scrapping, thus losing their tightening function. In addition, when the porcelain insulators are replaced, the power lines need to be replaced, making the original lines unusable, thereby causing a waste of resources.

[0004] Therefore, we propose a porcelain insulator provided with a tightening wire assembly in order to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides a technical solution: a porcelain insulator provided with a tensioning assembly, comprising an insulator body 1, a connector 2 installed on the top of the insulator body 1, and a junction box 3 connected above the connector 2, upper fixed blocks 4 connected at both ends of the junction box 3, and a connecting column 7 installed at the bottom of the upper fixed block 4, a first spring 5 installed on the periphery of the connecting column 7, and the first spring 5 is connected to the inner side of the upper fixed block 4 and the lower fixed block 6, a lower fixed block 6 is provided at the bottom of the connecting column 7, tensioning structures 8 are provided on both sides of the top of the insulator body 1, a fixing groove 9 is opened on the top of the insulator body 1, and a limit block 10 is provided on the bottom side of the inside of the insulator body 1.

[0025] The junction box 3 is divided into two parts, the upper and lower parts of the junction box 3 are connected by a hinge, and the lower part of the junction box 3 is in a rotating structure with the upper part of the junction box 3 through the hinge. The lower part of the junction box 3 is rotated by the hinge to expose the top of the connector 2. The metal wire is then connected through the connector 2 so that the metal wire is installed inside the junction box 3, thereby reducing the damage to the connection caused by external natural factors, thereby increasing the duration of the tightening effect.

[0026] A slot is provided inside the lower fixed block 6 to adapt to the bottom of the connecting column 7, and the connecting column 7 forms a sliding structure with the lower fixed block 6 through the slot. By pulling the upper fixed block 4, the first spring 5 on the periphery of the connecting column 7 is stretched, thereby increasing the size of the central wire inlet, thereby increasing the audience of metal wire size.

[0027] The wire tightening structure 8 includes a handle 801, a connecting rod 802, a connecting block 803, a rotating rod 804, a wire tightening column 805, a second spring 806, a connecting plate 807 and a fixing column 808. One side of the bottom of the handle 801 is connected with a connecting block 803, and a rotating rod 804 is installed at the left end of the connecting block 803. A wire tightening column 805 is arranged at the bottom of the rotating rod 804. A connecting rod 802 penetrates through the inside of the handle 801, and a connecting plate 807 is arranged at the bottom of the connecting rod 802. A second spring 806 is installed around the connecting rod 802. A fixing column 808 is installed at the center of the bottom of the connecting plate 807. Wind the metal wire around the wire tightening column 805, and then pull the connecting rod 802 to move the fixing column 808 at the bottom of the connecting rod 802 upward, so as to release the fixation of the rotating rod 804, and then rotate it through the handle 801, thereby driving the wire tightening column 805 at the bottom of the rotating rod 804 to rotate, so as to tighten it. When tightened to the required position, release the pulling force on the connecting rod 802 to reset the second spring 806 arranged at the top of the connecting plate 807, so that the fixing column 808 is clamped into the fixing groove 9 at the top of the wire collecting box 3 for fixation.

[0028] The fixing groove 9 opened at the top of the wire collecting box 3 is adapted to the bottom of the fixing column 808, and the fixing grooves 9 are equidistantly distributed at the top of the wire collecting box 3. By clamping the fixing column 808 into the fixing groove 9, the wire tightening column 805 is fixed, thereby preventing the metal wire from driving the wire tightening column 805 to rotate and slip off.

[0029] The limiting blocks 10 at the bottom side of the inner part of the wire collecting box 3 are centrosymmetric. Place the metal wire between the limiting blocks 10 on the same side to reduce the knotting condition of the metal wire when rotating through the fixing column 808.

[0030] Working principle: When using the porcelain insulator provided with the wire tightening assembly, first, by pulling the upper fixing block 4, the first spring 5 around the connecting column 7 is stretched, so that the connecting column 7 slides on the lower fixing block 6 to increase the size of the central wire inlet. Then, pass the metal wire into the wire inlet, and then release the pulling force on the upper fixing block 4 to basically clamp the metal wire by the upper fixing block 4 for limiting, and such a structure increases the acceptance of the metal wire size;

[0031] After that, through openings are provided at both ends of the wire collecting box 3, and the lower part of the wire collecting box 3 rotates through a hinge to expose the upper end of the connecting piece 2 at the top of the insulator body 1. After the metal wire is limited, it enters through the through openings at both ends of the wire collecting box 3, and then wind the metal wire around the wire tightening column 805 to fix it. Then, after the metal wire is wound around the wire tightening column 805, connect one end of the metal wire to the connecting piece 2 again to install the metal wire inside the wire collecting box 3, thereby reducing the damage to the connection part by external natural factors and increasing the service life of the wire tightening function;

[0032] Next, after the wire is connected inside the wire collecting box 3, by pulling the connecting rod 802 inside the wire tightening structure 8, the fixing column 808 at the bottom of the connecting rod 802 is moved upward to release the fixation of the rotating rod 804. Then, by rotating the handle 801, the handle 801 drives the connecting block 803 to move. The connecting block 803 drives the rotating rod 804 to rotate within the bearing at the upper end of the wire collecting box 3, thereby driving the wire tightening column 805 at the bottom of the rotating rod 804 to rotate to tighten it. And the tightened wire will be stored inside the wire collecting box 3 to prevent damage to the wire caused by external natural factors. When tightened to the required position, the pulling force on the connecting rod 802 is released, and the second spring 806 provided at the top of the connecting plate 807 is reset, so that the fixing column 808 is snapped into the fixing groove 9 at the top of the wire collecting box 3 for fixation;

[0033] Finally, when the porcelain insulator needs to be disassembled and replaced at another position or extended, the wire stored inside the wire collecting box 3 is reversed via the fixing column 808 and pulled out, thereby increasing fault tolerance. And a limiting block 10 is installed on the bottom side inside the wire collecting box 3. By placing the wire between the limiting blocks 10 on the same side, the knotting condition of the wire during rotation via the fixing column 808 is reduced. And the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
