Description

Technical Field

[0001] This utility model relates to the field of power insulation technology, and in particular to an integrated copper slide rail segmented insulator. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the sectional insulator is an important piece of electrified railway equipment. It is mainly used to realize the electrical segmentation of the contact network and ensure that the locomotive pantograph can pass smoothly. Its main function is to disconnect the power to the faulty or repaired part of the contact network by opening the isolating switch at the sectional insulator when the contact network fails or needs to be shut down for maintenance, while the other parts can still be powered normally, thereby improving the reliability and flexibility of the contact network operation.

[0003] When the existing integrated copper slide rail segmented insulator is in use, the pantograph on the trolley is squeezed and rubbed against the lower end of the insulator when the trolley passes by. This squeezing impact causes the insulator to swing, which is detrimental to the overall stability. At the same time, the friction also causes metal powder to be generated in the slide rail of the insulator. This metal powder will fall onto the insulating rod. If it is not cleaned for a long time, it will reduce the insulation function of the insulating rod. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology. When the existing integrated copper slide rail segmented insulator is in use, when the tram passes by, the pantograph on the tram squeezes and rubs against the lower end of the insulator. This squeezing impact causes the insulator to swing, which is not conducive to the overall stability. At the same time, the friction also causes the insulator slide rail to generate metal powder. This metal powder will fall onto the insulating rod. Long-term lack of cleaning will reduce the insulating function of the insulating rod. Therefore, an integrated copper slide rail segmented insulator is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An integrated copper slide rail segmented insulator includes a slide rail and a first insulating rod, wherein a support plate is provided inside the slide rail, and the first insulating rod is fixedly connected to the support plate;

[0007] A cleaning component is fixedly connected inside the slide rail. The cleaning component includes a fixed plate, a piston cylinder, a jet chamber, a sponge ring, and a straight plate. Both fixed plates are fixed on the slide rail, and push rods are fixedly connected to the fixed plates. Squeezing plates are slidably connected inside the two piston cylinders. An air bladder is fixedly connected between the squeezing plate and the bottom wall of the piston cylinder. A T-shaped rod is fixedly connected between the two piston cylinders. Both jet chambers are fixedly connected to the support plate. The jet chambers and the air bladders are connected through an air inlet pipe. A sponge ring is rotatably connected to one end of the first insulating rod near the jet chamber. Multiple fan blades are installed in a ring array on the outer surface of the sponge ring. The straight plate is fixedly connected to one end of the sponge ring. Multiple scrapers are installed in a linear array on the straight plate. The multiple scrapers are rotatably connected to the outer surface of the first insulating rod.

[0008] Preferably, a first clamp is fixedly connected to one end of the slide rail, a second clamp is fixedly connected to the end of the first insulating rod away from the support plate, a third clamp is fixedly connected to one end of the T-shaped rod, a second insulating rod is fixedly connected to one end of the third clamp, and a fourth clamp is fixedly connected to the end of the second insulating rod away from the third clamp.

[0009] Preferably, a horizontal adjustment box is fixedly connected to each end of the slide, and a threaded rod is rotatably connected inside the horizontal adjustment box.

[0010] Preferably, one end of the threaded rod is fixedly connected to a first bevel gear, and one side of the horizontal adjusting box is rotatably connected to an adjusting rod.

[0011] Preferably, a second bevel gear is fixedly connected to one end of the adjusting rod near the first bevel gear, the first bevel gear meshing with the second bevel gear, and an annular scale is provided at the other end of the adjusting rod.

[0012] Preferably, the threaded rod is threadedly connected to a lifting plate, an elastic rope is fixedly connected to the upper end of the lifting plate, and a cable tie is fixedly connected to the end of the elastic rope away from the lifting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the tram passes the insulator, the push rod, the squeezing plate, and the airbag are used to buffer and prevent the insulator from swinging. At the same time, the airbag is compressed and the internal gas is applied to the fan blades of the sponge ring through the air intake pipe and the jet chamber. The fan blades are pushed by the gas, the sponge ring rotates and drives the straight plate to rotate. The rotation of the straight plate drives the scraper to clean the metal powder on the first insulating rod, so as to prevent the metal powder from affecting the insulation performance of the first insulating rod.

[0015] 2. When installing the insulator, rotate the adjusting rod on the horizontal adjusting box. Through the combined action of the threaded rod, the first bevel gear, the second bevel gear, the lifting plate, the elastic rope, and the cable tie, the insulator is adjusted to a horizontal state, thereby facilitating the installation by the workers.

[0023] Reference Figures 1-4An integrated copper slide rail segmented insulator includes a slide rail 1 and a first insulating rod 2. A support plate is provided inside the slide rail 1, and the first insulating rod 2 is fixedly connected to the support plate. The working principle of the first insulating rod 2 is the same as that of existing insulating rods. A cleaning component is fixedly connected inside the slide rail 1. The cleaning component includes a fixing plate 12, a piston cylinder 16, an air jet chamber 18, a sponge ring 19, and a straight plate 21. Both fixing plates 12 are fixed to the slide rail 1, and a push rod 13 is fixedly connected to the fixing plate 12. Squeezing plates 14 are slidably connected inside the two piston cylinders 16, and an airbag 15 is fixedly connected between the squeezing plate 14 and the bottom wall of the piston cylinder 16. A T-shaped rod 23 is fixedly connected between the two piston cylinders 16. Both air jet chambers 18 are fixedly connected to the support plate, and the air jet chambers 18 and the airbags 15 are connected through an air inlet pipe 17. Multiple air jet chambers 18 are provided with... The first insulating rod 2 has a sponge ring 19 rotatably connected to one end near the jet chamber 18. The sponge ring 19 is lightweight and easy to rotate. Multiple fan blades 20 are installed in a ring array on the outer surface of the sponge ring 19. The jet hole of one jet chamber 18 is oriented obliquely upward, and the jet hole of the other jet chamber 18 is oriented obliquely downward. This arrangement of jet holes can effectively ensure the rotation of the fan blades 20. A straight plate 21 is fixedly connected to one end of the sponge ring 19. Multiple scrapers 22 are installed in a linear array on the straight plate 21. The fan blades 20, the straight plate 21, and the scrapers 22 are all made of lightweight materials to ensure their light weight. The outer surface of the first insulating rod 2 has multiple insulating rings with grooves between the two insulating rings. The multiple scrapers 22 are rotatably connected to the outer surface of the first insulating rod 2, so that the scrapers 22 can clean the grooves between the insulating rings.

[0024] A first clamp 24 is fixedly connected to one end of the slide rail 1. A second clamp 25 is fixedly connected to the end of the first insulating rod 2 away from the support plate. A third clamp 26 is fixedly connected to one end of the T-shaped rod 23. A second insulating rod 3 is fixedly connected to one end of the third clamp 26. A fourth clamp 27 is fixedly connected to the end of the second insulating rod 3 away from the third clamp 26. The first clamp 24, the second clamp 25, the third clamp 26, and the fourth clamp 27 are existing technologies, and their working principle is the same as that of existing clamps. Horizontal clamps are fixedly connected to both ends of the slide rail 1. The horizontal adjustment box 4 is rotatably connected to a threaded rod 5. One end of the threaded rod 5 is fixedly connected to a first bevel gear 6. One side of the horizontal adjustment box 4 is rotatably connected to an adjustment rod 7. The end of the adjustment rod 7 near the first bevel gear 6 is fixedly connected to a second bevel gear 8. The first bevel gear 6 and the second bevel gear 8 mesh. The other end of the adjustment rod 7 is provided with an annular scale. The threaded rod 5 is threadedly connected to a lifting plate 9. The upper end of the lifting plate 9 is fixedly connected to an elastic rope 10. The end of the elastic rope 10 away from the lifting plate 9 is fixedly connected to a cable tie 11.

[0025] In this invention, when the tram passes the insulator, the tram's back arch slides on the slide rail 1. The slide rail 1 moves upward a certain distance under the pressure of the back arch. The movement of the slide rail 1 drives the fixed plate 12 and the push rod 13 to move upward. The movement of the push rod 13 pushes the extrusion plate 14 to move. The extrusion plate 14 extrudes the airbag 15. The gas in the airbag 15 is pressurized and enters the jet chamber 18 through the air inlet pipe 17. The gas in the jet chamber 18 is pressurized and acts on the fan blade 20 through the jet hole, thereby causing the fan blade 20 to rotate. The rotation of the fan blade 20 drives the sponge ring 19 to rotate. The rotation of the sponge ring 19 drives the straight plate 21 to make a circular motion. Thus, the scraper 22 on the straight plate 21 can effectively clean the metal powder on the first insulating rod 2, preventing the metal powder from accumulating on the first insulating rod 2 for a long time and affecting the insulation performance of the first insulating rod 2.

[0026] During insulator installation, the adjusting rods 7 on the two horizontal adjusting boxes 4 are rotated. The rotation of the adjusting rods 7 drives the threaded rod 5 to rotate via the first bevel gear 6 and the second bevel gear 8. The rotation of the threaded rod 5 causes the lifting plate 9 to move up and down, thereby pulling the elastic rope 10. One end of the elastic rope 10 is fixed to the cable tie 11, which is fixed to the high-voltage power line. Therefore, by rotating the adjusting rods 7, the elastic rope 10 is pulled, thus adjusting the level of the insulator to facilitate installation by workers.
