Automatic cleaning device for dirty overhead contact line insulators

Abstract

This utility model discloses an automatic cleaning device for contaminated contact wire insulators, comprising a rectangular frame, a rotating rod rotatably connected inside the movable frame, a rotating wheel fixed to the outer wall of the rotating rod, a displacement motor located below the rotating rod, and displacement synchronous wheels fixed to the output shaft of the displacement motor and the outer wall of the rotating rod, with displacement synchronous belts sleeved on the outer sides of the two displacement synchronous wheels. Two bidirectional screws are located above the rectangular frame, with two fixed frames rotatably connected to the outer walls of the bidirectional screws. The device is then connected to a busbar. Rotating the bidirectional screws moves the movable plate and the hanging wheel, which inserts into the busbar. Then, rotating the lifting screw causes the movable frame, displacement motor, rotating rod, and rotating wheel to rotate, with the rotating wheel contacting the bottom of the busbar. This increases the friction between the rotating wheel and the busbar, preventing insufficient friction from causing the device to malfunction.

[0012] Beneficial effects

[0013] This utility model provides an automatic cleaning device for contaminated overhead contact line insulators. Compared with the prior art, it has the following advantages:

[0014] 1. This automatic cleaning device for contaminated contact network insulators comprises a displacement motor, a moving frame, a lifting screw, a rotating rod, a rotating wheel, a displacement synchronous belt, a displacement synchronous wheel, a bidirectional screw, a moving plate, and a hanging wheel. The device is connected to the busbar. Then, rotating the bidirectional screw moves the moving plate and the hanging wheel, which inserts into the busbar. Next, rotating the lifting screw causes the moving frame, displacement motor, rotating rod, and rotating wheel to rotate. The rotating wheel contacts the bottom of the busbar, increasing friction between the rotating wheel and the busbar and preventing insufficient friction that would prevent the device from moving.

[0015] 2. This automatic cleaning device for contact network insulators, consisting of an arc-shaped frame, a displacement gear, a transmission rod, a rotating synchronous pulley, a rotating synchronous belt, and a rotating motor, enables the transmission rod and displacement gear to rotate via the rotating synchronous belt and rotating synchronous pulley. The rotation of the displacement gear causes the arc-shaped rack and arc-shaped frame to move, which in turn moves the round rod and brush bristles. This movement of the brush bristles expands their cleaning area, resulting in better cleaning of the contact network insulators. Attached Figure Description

Fixed plates 4 are fixed on both the left and right sides of the rectangular frame 1. An arc frame 2 is provided above the fixed plate 4. A round rod 20 is rotatably connected to the top of the arc frame 2. Brush filaments 5 are fixed to the outer wall of the round rod 20, which facilitates the disassembly of the device. A moving frame 27 is movably connected to the inner cavity of the rectangular frame 1. The left side of the displacement motor 26 is fixedly connected to the left side of the inner interior of the moving frame 27. The two ends of the rotating rod 25 are rotatably connected to the left and right sides of the inner interior of the moving frame 27, respectively. A lifting screw 29 is screwed into the inner interior of the moving frame 27. The top end of the lifting screw 29 is rotatably connected to the bottom of the fixed frame 7, which allows the rotating wheel 8 and the busbar to be in close contact.

[0024] Furthermore, a transmission rod 3 is rotatably connected inside the fixed plate 4, and a displacement gear 19 is fixed to the top of the transmission rod 3. An arc-shaped rack 31 is fixed to the inner side wall of the arc-shaped frame 2, and the arc-shaped rack 31 and the displacement gear 19 are meshed together, so that the round rod 20 and the brush bristles 5 can move. A rotating motor 23 is fixed to the inner front surface of the rectangular frame 1. The output shaft of the rotating motor 23 and the outer side wall of the transmission rod 3 are both fixed with rotating synchronous pulleys 14. A rotating synchronous belt 13 is sleeved on the outer side of the three rotating synchronous pulleys 14, so that the displacement gear 19 can rotate. Arc-shaped grooves 18 are opened on the outer and inner rings of the outer side wall of the arc-shaped frame 2. The top of the fixed plate 4 is fixed.

The rotating motor 23 drives the drive rod 3 and the displacement gear 19 to rotate via the rotating synchronous belt 13 and the rotating synchronous pulley 14. The rotation of the displacement gear 31 causes the arc-shaped rack 19 and the arc-shaped frame 2 to move. The arc-shaped frame 2 moves the round rod 20 and the brush filaments 5, thus moving the brush filaments 5 and expanding their cleaning area for better cleaning of the contact wire insulator.
