Technical Field
[0001] The utility model relates to the technical field of circuit maintenance, and particularly to an automatic cleaning machine for onshore switchyard bushings. Background Art
[0002] The reactor bushings and transformer bushings of onshore switchyards are long-term exposed to the outdoor environment, and are extremely prone to accumulating dust, salt, grease and various adhesives. These dirt not only affect the appearance of the equipment, but more importantly, they will reduce the insulation performance of the bushings, increase the risk of partial discharge and flashover, and seriously threaten the safe and stable operation of the power system.
[0003] Traditional manual cleaning methods require workers to climb ladders for operation, which has the risk of falling from height, high labor intensity, low cleaning efficiency, and it is difficult to ensure the consistency of cleaning quality. Especially for large bushings with a height of 5-10 meters and a diameter of 30 cm, the limitations of manual cleaning are more obvious. Content of the Utility Model
[0004] In view of the deficiencies of the prior art, the utility model provides an automatic cleaning machine for onshore switchyard bushings, which solves the problem of inconvenient high-altitude manual cleaning in the background art.

[0007] Further, the telescopic mechanism includes a hydraulic telescopic sleeve and a limiting rod. The hydraulic telescopic sleeve is fixedly installed between the support semi-ring and the chassis semi-ring. The limiting rod is fixedly installed on the outer ring of the chassis semi-ring. The support semi-ring is slidably connected with the limiting rod.
[0008] Further, one end of the gear ring semi-ring is fixedly installed with a limiting baffle, the bottom end of the gear ring semi-ring is fixedly installed with a limiting guide rail, and the support semi-ring is provided with a "convex"-shaped limiting groove adapted to the gear ring semi-ring.
[0009] Furthermore, the nozzle has hinge shafts at both ends, and support plates that are hinged to the hinge shafts are provided on both sides of the nozzle. The support plates are fixedly connected to the support semi-rings, and a rotation mechanism for controlling the rotation of the hinge shafts is installed on one side of the support plate.
[0010] Furthermore, the cleaning mechanism also includes an ultrasonic cleaning module installed above the toothed ring semi-ring and in front of the nozzle rotation direction, with the ultrasonic cleaning module pointing towards the center of the toothed ring semi-ring.

[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This automated bushing cleaning machine for land-based switch stations uses an existing lifting mechanism to control the chassis half-ring to fit onto the outer surface of the bushing. The toothed half-ring rotates along the bushing, allowing the cleaning mechanism above the toothed half-ring to rotate and clean along the bushing. The telescopic mechanism controls the toothed half-ring to move up and down to clean the circumferential surface of the bushing.
[0015] 2. This automated bushing cleaning machine for onshore switch stations has an extension arm fixedly installed on the inner ring of the chassis semi-ring, with the extension arm pointing towards the center.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figures 1-4 An automated bushing cleaning machine for onshore switchgear includes a chassis semi-ring 1, which is raised and lowered by an existing lifting mechanism. A telescopic mechanism 2 is located above the chassis semi-ring 1. A supporting semi-ring 3 is located at the moving end of the telescopic mechanism 2. A geared semi-ring 4 is rotatably connected to the upper surface of the supporting semi-ring 3. A power source 5 is installed on the supporting semi-ring 3 to drive the geared semi-ring 4 to rotate. A cleaning mechanism 6, which rotates with the geared semi-ring 4, is installed on the upper surface of the geared semi-ring 4. The cleaning mechanism 6 includes a nozzle 7. The inlet end of the nozzle 7 is connected to and passes through a connecting pipe 8 that prevents tangling during the rotation of the nozzle 7. The connecting pipe 8 is located away from the nozzle. One end of 7 is connected to and passes through an electromagnetic reversing valve 9 with three inlets. The three inlets of the electromagnetic reversing valve 9 are respectively connected to and pass through a cleaning agent spray pipe 101, a high-pressure water spray pipe 102, and a high-pressure gas spray pipe 103. The supply units corresponding to the three pipes are set on the bottom surface. The chassis half-ring 1 is controlled to fit onto the outer surface of the sleeve by the existing lifting mechanism, and rotates along the collar by the toothed half-ring 4, so that the cleaning mechanism 6 above the toothed half-ring 4 can rotate and clean along the collar. The toothed half-ring 4 is controlled to move up and down by the telescopic mechanism 2 to clean the circumferential surface of the collar.
[0023] The telescopic mechanism 2 includes a hydraulic telescopic sleeve 201 and a limiting rod 202. The hydraulic telescopic sleeve 201 is fixedly installed between the supporting half-ring 3 and the chassis half-ring 1. The limiting rod 202 is fixedly installed on the outer ring of the chassis half-ring 1. The supporting half-ring 3 is slidably connected to the limiting rod 202. The hydraulic telescopic sleeve 201 and the limiting rod 202 are a telescopic device with low manufacturing cost. At the same time, in order to accurately control the movement, the telescopic sleeve can be adjusted to a ball screw drive.
[0024] A limiting baffle 401 is fixedly installed at one end of the gear ring half ring 4, and a limiting guide rail 402 is fixedly installed at the bottom end of the gear ring half ring 4. The supporting half ring 3 has a "convex" shaped limiting groove that matches the gear ring half ring 4. This setting can prevent the gear ring half ring 4 from detaching from the supporting half ring 3.
[0025] The nozzle 7 has hinge shafts at both ends, and support plates 702 that are hinged to the hinge shafts are provided on both sides of the nozzle 7. The support plates 702 are fixedly connected to the support half ring 3. One of the support plates 702 is equipped with a rotating mechanism 703 that controls the rotation of the hinge shaft. The rotating mechanism 703 is a motor. The motor controls the rotation of the hinge shaft, so that the nozzle 7 can swing at any angle and increase the cleaning range.
[0026] The cleaning mechanism 6 also includes an ultrasonic cleaning module 704 installed above the toothed ring semi-ring 4 and in front of the nozzle 7 in the direction of rotation. The ultrasonic cleaning module 704 points to the center of the toothed ring semi-ring 4. By setting the ultrasonic cleaning module 704, ultrasonic waves can be emitted to clean the sleeve.
[0027] An extension arm 11 is fixedly installed on the inner ring of the chassis semi-ring 1, with the extension arm 11 pointing towards the center. A collection sleeve 12, concentric with the chassis semi-ring 1, is fixedly installed on the end of the extension arm 11 away from the chassis semi-ring 1. A return water pipe 13 is provided at one end of the collection sleeve 12. The inner wall of the collection sleeve 12 is made of elastic foam material, which can form a seal by tightly adhering to the sleeve. This arrangement allows the collection sleeve 12 to be fitted onto the bottom of the sleeve, so that the clean sewage can be collected back.
[0028] The collecting sleeve 12 consists of two symmetrical parts that are hinged together. One part is fixedly connected to the extension arm 11, and the other part is driven to rotate by a drive mechanism 14 mounted on the surface of the extension arm 11 and close with the fixed part. The drive mechanism 14 is a motor. The motor adjusts the hinge shaft to rotate, so that the two parts of the collecting sleeve 12 can close together to form a complete cavity.
[0029] In use, the existing lifting mechanism controls the chassis half-ring 1 to fit onto the outer surface of the sleeve, and the toothed half-ring 4 rotates along the collar, so that the cleaning mechanism 6 above the toothed half-ring 4 can rotate and clean along the collar. The telescopic mechanism 2 controls the toothed half-ring 4 to move up and down to clean the circumferential surface of the collar.
[0030] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
