[0017] Technical effects and advantages of the present invention:

[0018] 1. The tension part provided in the present invention enables the cable to slide slightly on the steel cap when the staff adjusts the tension wire clamp to control the tension between the cable and the insulator, allowing the insulator to flexibly adapt to different tension requirements and make fine adjustments, thereby ensuring the stability and safety of the cable system. Through the tension stretching, the connection strength between the steel cap, the connector and the porcelain part is enhanced, which further ensures the stability and reliability of the cable system when subjected to tensile force;

[0019] 2. When the vibration of the cable returns to stability, the elastic force of the first spring will push the sliding part to reset. As the sliding part resets, the extruding part will work in the opposite direction and push the connecting part upward. This upward pushing force will make the connection between the porcelain part, sleeve and steel cap slightly loose, but will not affect the stability of the connection, so that the insulator has a certain elasticity, so that it can better meet the tension requirements of the cable;

[0020] 3. The heat dissipation assembly provided in the present invention can effectively dissipate heat for porcelain parts, which not only enhances the connection strength between porcelain parts, insulating parts and steel caps, but also can utilize rainwater to naturally cool down the insulators. Through the combined effect of the heat dissipation assembly and rainwater, the thermal stability of the insulators is significantly improved, thereby extending the service life of the insulators.

[0021] 4. Through the water storage plates distributed in a rectangular array, on rainy days, rainwater flows into the water storage cavity through the water inlet trough, naturally dissipating heat for the fixed collar and taking away part of the heat. When rainwater accumulates in the water storage plate to a certain height and overflows the water inlet, the pressure sensor will detect the pressure change and automatically drive the solenoid valve to open and release the rainwater in the water storage plate. At this time, the rainwater will flush the fixed collar when it flows out, removing the dust attached to its surface;

[0022] 5. The setting of the elastic sheet can effectively absorb and disperse the extrusion force on the steel cap when the cable is in a taut state due to tension, reducing the impact on the steel cap when the cable is taut, ensuring that the cable and the insulator can still maintain a tight connection when the tension is high, while also reducing the risk of damage to the steel cap due to excessive force and increasing the service life of the insulator.

[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] The present invention provides Figure 1 - Figure 5 A tension-resistant rod-shaped suspension porcelain insulator shown in the figure comprises a porcelain part 1, an insulating part 2, and a steel cap 3 and a steel foot 4 arranged at both ends of the insulating part 2. The sheds of the porcelain part 1 are fixedly arranged on the outer wall of the insulating part 2 in a large and a small shape and equidistant manner, which can effectively isolate the insulator from pollutants in the external environment, such as dust, fallen leaves, etc., to ensure that the insulator is always kept clean and dry, thereby maintaining its good insulation performance. Secondly, the size matching and equidistant distribution of the sheds can enhance the windproof ability of the insulator, protect the insulator from the influence of wind in a windy environment, and help to reduce the overall weight of the insulator, making the installation and maintenance process more convenient.

[0031] The insulating part 2 is connected to the steel cap 3 through the tension part, so that when the staff adjusts the tension rope clamp to control the tension between the cable and the insulator, the cable can slide slightly on the steel cap 3, allowing the insulator to flexibly adapt to different tension requirements and make fine adjustments, thereby ensuring the stability and safety of the cable system. Through the tension stretching, the connection strength between the steel cap 3, the connector 506 and the porcelain part 1 is enhanced, which further ensures the stability and reliability of the cable system when subjected to tensile force.

[0032] The tensioning part includes a sleeve 501, which is fixedly arranged at one end of the insulating part 2 close to the steel cap 3. The upper end of the sleeve 501 is fixed to the steel cap 3. A sliding groove 502 is provided on the inner wall of the steel cap 3. A sliding member 503 is slidably arranged on the inner wall of the sliding groove 502. The sliding member 503 is in an inverted U-shaped structure, which can more effectively fix the cable. When the cable passes through the steel cap 3 and fits tightly on the steel cap 3, the sliding member 503 with the U-shaped structure can hook the cable more firmly, ensuring that the cable remains stable when subjected to tension and is not easy to slip.

[0033] A first spring 504 is fixedly provided on the inner wall of the slide groove 502, one end of the first spring 504 is fixed to the sliding member 503, an extrusion member 505 is provided on the opposite side of the sliding member 503, a connecting member 506 is slidably provided on the inner wall of the steel cap 3, and both sides of the connecting member 506 are in extrusion contact with the extrusion member 505;

[0034] A fixing ring 507 is fixedly provided on the surface of the ceramic part 1, and the surface of the fixing ring 507 is fixed to the bottom of the sleeve 501. A heat-conducting column 508 is penetrated between the ceramic parts 1, and the heat-conducting column 508 passes through the sleeve 501 and is plugged into the inner wall of the steel cap 3. A first fixing plate 509 is fixedly provided at one end of the heat-conducting column 508 close to the steel cap 3, and a second fixing plate 510 is fixedly provided at the bottom of the connecting piece 506, and the bottom passes through the first fixing plate 509 and the second fixing plate 510 and is plugged into the sleeve 501, and a gasket 8 is fixedly provided on the outer wall of the connecting piece 506, and the bottom of the gasket 8 contacts with the surface of the second fixing plate 510 to increase the friction with the second fixing plate 510.

[0035] When the cable is shaken or jittered, the cable will pull the sliding block to slide along the slide groove 502 in the steel cap 3. When the sliding member 503 moves upward, it will simultaneously drive the two extrusion members 505 to rise together. At this time, they will squeeze the first spring 504 and act on the connecting member 506 at the same time. Through the setting of the inclined surface, the connecting member 506 will be squeezed downward by the downward extrusion force. During the downward sliding process of the connecting member 506, it will squeeze the first fixing plate 509 and the second fixing plate 510 at the same time, further strengthening the degree of insertion between the connecting member 506 and the inner wall of the sleeve 501. At the same time, the gasket 8 on the outer wall of the connecting member 506 will squeeze the second fixing plate 510 more tightly, ensuring that the connectivity of the steel cap 3 is still stable even when the cable is stretched.

[0036] When the vibration of the cable returns to stability, the elastic force of the first spring 504 will push the sliding member 503 to reset. As the sliding member 503 resets, the extruding member 505 will act in the opposite direction to push the connecting member 506 upward. This upward pushing force will make the connection between the porcelain part 1, the sleeve 501 and the steel cap 3 slightly looser, but will not affect the stability of the connection, so that the insulator has a certain elasticity, so that it can better adapt to the tension resistance requirements of the cable.

[0037] Furthermore, considering that the insulator may generate heat during operation, a heat dissipation component for dissipating the heat of the porcelain part 1 is provided on the fixed ring 507, which effectively dissipates the heat of the porcelain part 1. This not only enhances the connection strength between the porcelain part 1, the insulating part 2 and the steel cap 3, but also can utilize rainwater to naturally cool the insulator. Through the combined action of the heat dissipation component and rainwater, the thermal stability of the insulator is significantly improved, thereby extending the service life of the insulator.

[0038] The heat dissipation component includes a water storage chamber 601 for storing rainwater. The water storage chamber 601 is opened on the inner wall of the fixed ring 507. The outer wall of the fixed ring 507 is evenly spaced with multiple drainage ports 602, which are connected to the water storage chamber 601.

[0039] A plurality of water inlets 603 are equidistantly provided on the surface of the fixed collar 507, the lower ends of the water inlets 603 are connected to the water storage chamber 601, and the drain outlet 602 is gradually inclined on one side close to the water storage chamber 601, which helps to increase the drainage speed and enable the water to be discharged more smoothly and quickly.

[0040] When the insulator is working, heat will be generated between the porcelain parts 1. In order to effectively dissipate the heat, the heat is quickly transferred from between the porcelain parts 1 to the uppermost porcelain part 1 through the heat-conducting column 508. On rainy days, rainwater flows into the water storage chamber 601 through the water inlet 603. The water storage chamber 601 stores the rainwater. As the rainwater continues to accumulate, when the water level exceeds the drain port 602, the rainwater in the water storage chamber 601 will flow out naturally. In this process, the rainwater not only takes away the excess water in the water storage chamber 601, but also takes away the heat generated by the porcelain part 1 during operation, thereby achieving effective heat dissipation of the insulator.

[0041] Furthermore, considering that the dust attached to the surface of the fixed ring 507 is not easily dropped by raindrops, a water storage plate 701 is fixed on the surface of the fixed ring 507, and multiple water storage plates 701 are provided. The multiple water storage plates 701 are distributed in a rectangular array, and one side of the water storage plate 701 is fixed to the outer wall of the sleeve 501. A water inlet groove 702 is opened on the surface of the water storage plate 701, and the water inlet groove 702 is connected to the water inlet 603. A solenoid valve is provided on the side of the water storage plate 701 away from the sleeve 501, and a pressure sensor 704 is provided on the surface of the fixed ring 507. The solenoid valve and the pressure sensor 704 are electrically connected, and the existing conventional technical means are not repeated here.

[0042] During use, on rainy days, rainwater is also used to clean the fixed collar 507. When rainwater drops on the water storage plate 701, it will flow into the water storage chamber 601 through the water inlet groove 702. In this process, the rainwater not only brings a natural heat dissipation effect to the fixed collar 507, but also takes away part of the heat through its flow, helping to reduce the temperature of the insulator. At the same time, when the rainwater accumulates to a certain height and overflows the water inlet 603, the pressure sensor 704 will quickly sense the change in pressure. Once a high pressure is detected, the solenoid valve will be driven to open to discharge the rainwater in the water storage plate 701. When the solenoid valve is opened, the rainwater will flow out and wash away the dust attached to the collar.

[0043] Taking into account that the cable will generate greater friction when stretching the sliding member 503, an arc-shaped groove 604 is opened on the steel cap 3, and a second spring 605 is fixedly provided on the inner wall of the arc-shaped groove 604. One end of the second spring 605 is fixed with an elastic sheet 606, and the elastic sheet 606 is fitted with the outer wall of the arc-shaped groove 604. The setting of the elastic sheet 606 can effectively absorb and disperse the extrusion force generated on the steel cap 3 when the cable is in a taut state due to tension, thereby reducing the impact on the steel cap 3 when the cable is taut, ensuring that the cable and the insulator can still maintain a tight connection when the tension is large, while also reducing the risk of damage to the steel cap 3 due to excessive force, thereby increasing the service life of the insulator.

[0044] Furthermore, anti-slip cotton is fixedly provided on one side of the elastic sheet 606 away from the spring to reduce wear between the cable and the elastic sheet 606 .

[0045] The arc-shaped structure can fit on the surface of the ceramic component 1, ensuring close contact between the two. This fitting design not only enables the fixing ring 507 to more effectively disperse and evenly distribute the force when the ceramic component 1 is subjected to pressure or tension, thereby reducing the stress effect on the ceramic component 1. At the same time, during the heat dissipation process, the close fit of the arc-shaped ring also enables it to more effectively absorb the heat on the surface of the ceramic component 1, thereby achieving a more efficient heat dissipation effect.
