Description

Technical Field

[0001] The invention belongs to the technical field of transformer cleaning and relates to a live cleaning device for a distribution transformer. Background Art

[0002] Distribution transformers are key equipment in the power system, used to change voltage levels to meet the needs of power transmission, distribution and consumption. During long-term operation, due to the influence of environmental factors (such as dust, moisture, salt spray, etc.), dirty substances are prone to accumulate on the external insulation surface of the transformer. These dirt may cause the insulation performance to deteriorate and increase the risk of partial discharge. In severe cases, it may cause equipment failure or power outages. Therefore, distribution transformers need to be cleaned regularly.

[0003] At present, when cleaning distribution transformers, live cleaning is usually used to avoid interference with other power users. When cleaning distribution transformers at high altitudes, workers often need to use high-pressure water guns with special live cleaning agents for flushing and cleaning. However, this manual cleaning method has many inconveniences in actual operation: on the one hand, during the cleaning process, a high-pressure water gun needs to be used to clean the distribution transformer. During the operation, the workers need to move around the distribution transformer repeatedly, and the operation process is relatively cumbersome. The overall cleaning efficiency is low, and due to the problem of operating height, thorough cleaning becomes difficult. Workers need to climb to mid-air for cleaning operations, and there are certain safety hazards during cleaning. Summary of the invention

DETAILED DESCRIPTION

[0027] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0028] A live cleaning device for a distribution transformer, such as Figure 1-Figure 4 As shown, it includes a mobile vehicle 1, a pressurized water tank 2, a spray pipe 3, a mounting structure and a cleaning mechanism. The mobile vehicle 1 is equipped with a pressurized water tank 2, and the liquid outlet end of the pressurized water tank 2 is equipped with a spray pipe 3, and the spray pipe 3 is a telescopic hose. The pressurized water tank 2 is externally connected to an inlet pipe, and a charged cleaning agent can be injected into the pressurized water tank 2 through the inlet pipe. The mobile vehicle 1 is provided with a mounting structure, and the mounting structure is provided with a cleaning mechanism for cleaning the distribution transformer 100.

[0029] like Figure 3 As shown, the mounting structure includes a sliding rod 41 and a mounting frame 42 . The sliding rod 41 is slidably connected to the right side of the moving vehicle 1 . The sliding rod 41 can slide up and down along the moving vehicle 1 . The top of the sliding rod 41 is connected to the mounting frame 42 .

[0030] like Figure 3 and Figure 4 As shown, the cleaning mechanism includes a connecting frame 51, a liquid guide tube 52, an arc-shaped clamping plate 53, an arc-shaped mounting plate 54, an arc-shaped nozzle 55 and an opening and closing structure. The connecting frame 51 is connected to the middle of the top of the mounting frame 42. The connecting frame 51 is rotatably connected to two arc-shaped clamping plates 53 on the right side. When the two arc-shaped clamping plates 53 are put together, they can be sleeved on the outside of the distribution transformer 100. The upper and lower sides of the two arc-shaped clamping plates 53 are connected to the arc-shaped mounting plates 54. The arc-shaped nozzle 55 is installed in the arc-shaped mounting plate 54. The four arc-shaped nozzles 55 and the liquid spraying pipe 3 are all connected by the liquid guide tube 52, so that the charged cleaning agent in the liquid spraying pipe 3 can be injected into the arc-shaped nozzle 55 through the liquid guide tube 52, so that the arc-shaped nozzle 55 sprays the charged cleaning agent on the distribution transformer 100 to clean the distribution transformer 100. An opening and closing structure for controlling the opening and closing of the arc-shaped clamping plate 53 is provided between the mounting frame 42 and the arc-shaped clamping plate 53.

[0031] like Figure 4 As shown, the opening and closing structure includes a cylinder 61 and a connecting seat 62. The cylinder 61 is installed on both the front and rear sides of the top of the mounting frame 42. The connecting seats 62 are connected to the left sides of the two arc-shaped clamping plates 53. The telescopic rod of the cylinder 61 is hingedly connected to the connecting seat 62, so that the telescopic rod of the cylinder 61 can drive the arc-shaped clamping plate 53 to swing through the connecting seat 62 when extending and retracting, so that the arc-shaped clamping plate 53 opens and closes.

[0032] like Figure 5-Figure 7 As shown, it also includes a controlled lifting mechanism, which includes a driving motor 71, a guide sleeve 72, a worm 73 and a worm wheel 74. The right side of the top of the mobile vehicle 1 is rotatably connected with a guide sleeve 72, and the guide sleeve 72 is sleeved on the outside of the sliding rod 41. The guide sleeve 72 is provided with internal threads, and the outside of the sliding rod 41 is provided with external thread grooves. The internal threads of the guide sleeve 72 are meshed with the external thread grooves of the sliding rod 41, so that the guide sleeve 72 and the sliding rod 41 are threadedly matched, so that the guide sleeve 72 can drive the sliding rod 41 to move up and down through the threads when rotating. A driving motor 71 is installed in the middle of the top of the mobile vehicle 1, and a worm 73 is connected to the output shaft of the driving motor 71. A worm wheel 74 is connected to the lower part of the guide sleeve 72, and the worm wheel 74 is meshed with the worm 73, so that the driving motor 71 can drive the guide sleeve 72 to rotate through the worm 73 and the worm wheel 74 during operation, thereby controlling the lifting of the sliding rod 41.

[0033] When the distribution transformer 100 needs to be cleaned live, the cleaning device can be used. When in use, the device is first moved to the edge of the distribution transformer 100 that needs to be cleaned by the mobile vehicle 1, and then the driving motor 71 is controlled to drive the worm gear 74 to rotate through the worm 73. The worm gear 74 drives the guide sleeve 72 to rotate when rotating. The guide sleeve 72 rotates and drives the sliding rod 41 to rise through the thread. The rising of the sliding rod 41 can drive the mounting frame 42 to rise, thereby driving the arc clamping plate 53 to rise. At this time, the arc clamping plate 53 is in the open state. Figure 2As shown, when the arc-shaped clamping plate 53 moves to the upper part of the distribution transformer 100, the mobile vehicle 1 is continuously pushed so that the arc-shaped clamping plate 53 moves to surround the distribution transformer 100. At this time, the telescopic rod of the cylinder 61 is controlled to extend through the connecting seat 62 to drive the arc-shaped clamping plate 53 to swing. The swing of the arc-shaped clamping plate 53 can completely cover the distribution transformer 100. At this time, the pressurized water tank 2 is controlled to inject the charged cleaning agent into the spray pipe 3. The charged cleaning agent in the spray pipe 3 will enter the arc-shaped nozzle 55 through the liquid guide pipe 52, and then the charged cleaning agent will be sprayed out through the arc-shaped nozzle 55, so that the charged cleaning agent is sprayed on the distribution transformer 100 to clean the distribution transformer 100. During the cleaning process, the driving motor 71 is controlled. The worm 73 is driven to rotate in the opposite direction. When the worm 73 rotates in the opposite direction, it can drive the guide sleeve 72 to rotate in the opposite direction through the worm gear 74. The reverse rotation of the guide sleeve 72 can drive the sliding rod 41 and the mounting frame 42 to descend, thereby driving the arc clamping plate 53, the arc mounting plate 54 and the arc nozzle 55 to descend. The arc nozzle 55 sprays charged cleaning agent while descending, which can achieve the effect of cleaning the outside of the distribution transformer 100. In this way, the distribution transformer 100 can be cleaned by using the cleaning device, and during the cleaning process, the distribution transformer 100 can be surrounded and the outside of the distribution transformer 100 can be cleaned at the same time. The cleaning efficiency is higher, and there is no need for staff to climb to operate, which is safer during operation.

[0034] like Figure 5 and Figure 6 As shown, a guide structure is also included, and the guide structure includes a guide sleeve 81 and a guide rod 82. Two guide sleeves 81 are connected to the right side of the top of the mobile vehicle 1, and the two guide sleeves 81 are respectively located on the front and rear sides of the guide sleeve 72. A guide rod 82 is slidably connected in the guide sleeve 81, and the top of the guide rod 82 is connected to the bottom of the mounting frame 42. When the mounting frame 42 moves up and down, the movement of the mounting frame 42 can be guided by the guide sleeve 81 and the guide rod 82 to ensure the stability of the mounting frame 42 during the up and down movement.

[0035] like Figure 8 and Fig. 9As shown, a brushing mechanism is also included, which includes a servo motor 91, a collar 92, an arc-shaped brush plate 93, a brush 94, a driving gear 95 and a transmission gear 96. The servo motor 91 is installed in the middle of the outer side of the two arc-shaped clamping plates 53, and the inner side of the two arc-shaped clamping plates 53 is rotatably connected with the collar 92. The two collars 92 are put together into a ring and can be sleeved on the outer side of the distribution transformer 100. The collar 92 is installed with an arc-shaped brush plate 93, and a plurality of brushes 94 are evenly spaced and connected in the arc-shaped brush plate 93. The outer arc surface of the collar 92 is evenly spaced with tooth grooves. The output shaft of the servo motor 91 is connected with a driving gear 95, and the middle of the outer side of the two arc-shaped clamping plates 53 is rotatably connected with the transmission gear 96. The two sides of the transmission gear 96 are respectively meshed with the tooth groove and the driving gear 95, so that the servo motor 91 can drive the collar 92 to rotate through the driving gear 95, the transmission gear 96 and the tooth groove when operating.

[0036] After the arc-shaped clamping plate 53 covers the distribution transformer 100, the brush 94 also contacts the distribution transformer 100. At this time, the servo motor 91 can be controlled to operate. When the servo motor 91 is in operation, it can drive the driving gear 95 to rotate. When the driving gear 95 rotates, it can drive the transmission gear 96 to rotate. When the transmission gear 96 rotates, it can drive the collar 92 to rotate through the tooth groove. When the collar 92 rotates, it can drive the arc-shaped brush plate 93 to rotate. The rotation of the arc-shaped brush plate 93 can drive the brush 94 to rotate. When the brush 94 rotates, the distribution transformer 100 can be scrubbed. After the arc-shaped nozzle 55 below sprays the charged cleaning agent on the distribution transformer 100, the brush 94 can scrub the distribution transformer 100. Finally, the arc-shaped nozzle 55 above rinses it again. In this way, the distribution transformer 100 can be cleaned by rinsing, scrubbing and then rinsing, thereby ensuring the effect of cleaning the distribution transformer 100.

[0037] like Fig.10 As shown, a shielding cover 10 is also included. The bottom of the lower arc-shaped mounting plate 54 is connected to the shielding cover 10. When the clean charged cleaning agent falls, it will be shielded by the shielding cover 10, so that the charged cleaning agent slides along the inner wall of the shielding cover 10 to avoid the charged cleaning agent splashing during the falling process, thereby ensuring the surrounding environment during the cleaning process and preventing the charged cleaning agent from splashing on the staff and dirtying their clothes.

[0038] like Fig.10 and Fig.11As shown, it also includes an injection mechanism, which includes an arc-shaped injection guide frame 111 and an air injection pipe 112. The tops of the two upper arc-shaped mounting plates 54 are connected to the arc-shaped injection guide frames 111. The two arc-shaped injection guide frames 111 can be sleeved on the outside of the distribution transformer 100 when they are close together. The left sides of the two arc-shaped injection guide frames 111 are connected with an air injection pipe 112. The air injection pipe 112 can be connected to an external air injection device. Air is injected into the arc-shaped injection guide frame 111 through the air injection device and the air injection pipe 112. The arc-shaped injection guide frame 111 sprays the gas on the cleaned distribution transformer 100, thereby drying the excess charged cleaning agent on the distribution transformer 100, avoiding the subsequent dust from being attached to the distribution transformer 100 due to the moisture on the surface of the distribution transformer 100, so as to achieve the effect of drying the cleaned distribution transformer 100.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
