Description

Technical Field

[0001] The invention relates to the technical field of transformer cooler cleaning, in particular to an intelligent cleaning device for an ultra-high voltage or extra-high voltage transformer cooler. Background Art

[0002] The transformer cooler is a heat exchange device that improves the heat exchange efficiency mainly by forcing oil to circulate and increasing the heat dissipation area. It aims to transfer the heat generated by transformer losses through heat dissipation to keep the transformer operating within a normal and safe temperature range.

[0003] As the transformer is used for a longer time, impurities and dirt are likely to accumulate inside the cooler. These dirt will affect the normal operation of the cooler and even cause transformer failure. Therefore, a regular cleaning device is required to clean the impurities and dirt inside the cooler to ensure the normal operation of the cooler and the safe operation of the transformer.

[0004] During the flushing process of the existing intelligent cleaning device for transformer cooler, since the transformer cooler is cooled by oil, as the use time goes by, a large amount of dirt in the transformer will adhere to the surface of the inner tube of the transformer cooler along with the flow of cooling oil, so that there are a large amount of impurities and dirt in the chemical cleaning solution generated by flushing. These impurities and dirt are easy to be blocked in the transformer cooler. For this, a filter is generally set to intercept and filter. As the number of cycle filtration increases, if the impurities and dirt are not cleaned in time and effectively during the working process, it is easy to cause the filter to be blocked, thereby reducing the cleaning efficiency of the transformer cooler cleaning device.

[0021] The present invention will be further described below in conjunction with the embodiments. Example 1

The output end of the driving cylinder 13 is connected to a telescopic shaft 14, and a convex mounting block 4 is fixedly installed on the lower end of the telescopic shaft 14. A filter screen 18 is provided on the inner side of the circulation box 2 near the collecting block 5. A sewage collection pipe 23 is fixedly installed on the upper end of one side of the circulation box 2, and a cleaning water outlet pipe 24 is fixedly installed on the lower end of the side of the circulation box 2 away from the sewage collection pipe 23. A circulating water pump 25 is installed on one side of the cleaning water outlet pipe 24, and a booster pump 26 is fixedly installed on the upper end of the support base 1 near the circulating water pump 25. The output end of the circulating water pump 25 is connected to the input end of the booster pump 26 by a No. 1 connecting pipe 27, and a No. 2 connecting pipe 28 is installed at the output end of the booster pump 26. A check valve 29 is installed at the end of the No. 2 connecting pipe 28 away from the output end of the booster pump 26, and a pressure sensor 30 is installed at the end of the check valve 29 away from the No. 2 connecting pipe 28. A nozzle 31 is installed at the end of the pressure sensor 30 away from the check valve 29, and a nozzle 32 is installed at the center of the end of the nozzle 31 away from the pressure sensor 30.

[0023] During the flushing process of the ultra-high voltage transformer cooler intelligent cleaning device, the ultra-high voltage transformer needs to be out of use, and the ultra-high voltage transformer is continuously cooled by other ultra-high voltage transformers. First, a cleaning liquid with equal proportion and uniform mixture is prepared, and the cleaning liquid raw materials are chemical cleaning agent and water. Then, the cleaning liquid is placed in the circulation box 2, and then the circulation water pump 25 is started, so that the cleaning liquid in the circulation box 2 can generate a pressure difference between the inlet and outlet through the rotation of the impeller inside the circulation water pump 25, thereby driving The cleaning liquid flows in the circulating water pump 25, and the booster pump 26 is started synchronously, driving the mechanical parts such as blades, gears or pistons inside the booster pump 26 to rotate or reciprocate, so that a negative pressure area is formed inside the booster pump 26, so that the cleaning liquid is sucked into the booster pump 26 body through the cleaning water outlet pipe 24 and the No. 1 connecting pipe 27. The liquid entering the booster pump 26 body gradually increases its pressure under the action of the mechanical parts. When the liquid is compressed to a sufficient pressure, the cleaning liquid is transported to the inside of the pressure sensor 30 through the No. 2 connecting pipe 28; When the cleaning liquid applies pressure to the pressure sensor 30, the sensitive element inside the pressure sensor 30 will be deformed or displaced, and then the mechanical change will be converted into an electrical signal output. The electrical signal is usually proportional to the pressure of the liquid. Therefore, the pressure value of the cleaning liquid can be known by measuring the size of the electrical signal. The measured electrical signal is transmitted to the control box set on one side of the circulation box 2 through the power line. The pressure of the cleaning liquid is displayed on the display in the control box. Then the cleaning liquid reaches the nozzle 31, and the dirt inside the transformer cooler is cleaned by inserting the nozzle 32 into the transformer cooler. A monitoring probe is installed on one side of the nozzle 32, so that when the inside of the transformer cooler is flushed through the nozzle 32, the monitoring probe first controls the amount of light entering the lens through the inner aperture, thereby adjusting the brightness of the image, and then focuses the light through the lens inside the monitoring probe, focusing the ambient light on the image sensor, so that the image sensor inside the monitoring probe is transmitted to the display in the control box through the power cord to form a clear image of the dirt cleaning situation inside the transformer cooler, so that the pressure of the cleaning solution can be controlled by the control box control panel set on one side of the circulation box 2, so that the pressure of the cleaning solvent can be adjusted according to the amount of dirt inside the transformer cooler, thereby achieving an intelligent cleaning function; The cleaning liquid and dirt cleaned from the transformer cooler are connected to the sewage collection pipe 23 through a conduit, and then the dirt in the chemical cleaning solution can be filtered and removed through the filter screen 18 in the circulation box 2, so that the cleaning liquid can be recycled. When the chemical cleaning solution circulates too many times, the dirt cleaned from the transformer cooler is also attached to the outer surface of the filter screen 18. At this time, the driving cylinder 13 is started synchronously, so that the telescopic shaft 14 drives the convex mounting block 4 to lift and slide inside the lifting groove 3 under the drive of the driving cylinder 13, thereby driving the convex mounting block 4 to lift and slide up and down synchronously, so that the scraper 10 also lifts and slides up and down synchronously. The dirt on the outer surface of the filter 18 is scraped off, and at the same time, the scraper 10 slides in the limit slot 7 through the sliding block 8 during the up and down lifting process, so that the special-shaped mounting block 9 can drive the scraper 10 without deviation. At the same time, when the scraper 10 is lifted up and down to scrape the filter 18, there will be a jam at the junction of two hard objects, and the telescopic spring 11 can allow the scraper 10 to be reversed when the scraper 10 is stuck when scraping the filter 18, thereby avoiding the scraper 10 from getting stuck during the lifting process of scraping the filter 18, thereby avoiding the impurities on the surface of the filter 18 from being cleaned in time, causing the filter 18 to be blocked, thereby improving the cleaning efficiency of the filter 18. Example 2

[0024] Reference Figure 1-6 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a collecting box 15 is fixedly installed on the upper end of the circulation box 2 away from the driving cylinder 13, a dust collector 16 is fixedly installed at the center of the upper end of the collecting box 15, a pump suction hose 17 is connected between the collecting box 15 and the collecting block 5, a collecting cover 19 is fixedly installed at the inner center of the collecting block 5, a rotating shaft 20 is symmetrically installed on both sides of the inner side of the collecting block 5 near the collecting cover 19, a plurality of rotating blades 21 are evenly spaced around the outer wall of the rotating shaft 20, and a collecting receiving plate 22 is installed below the end of one end of the collecting block 5 near the scraper mounting seat 6; After the dirt on the filter screen 18 is scraped off by the scraper 10, since the collecting plate 22 is below the scraper 10, the dirt naturally falls on the collecting plate 22 due to gravity, and the collecting plate 22 is in an inclined state. The rotating motor on one side of the collecting block 5 is started to rotate and drive the rotating shaft 20, so that the rotating blade 21 is driven by the rotating shaft 20 to rotate and collect the dirt on the collecting plate 22 into the collecting cover 19, and the vacuum cleaner 16 is started synchronously at the same time, so that the motor inside the vacuum cleaner 16 rotates at high speed. When rotating, it will drive the blades inside the vacuum cleaner 16 to rotate together, and the high-speed rotation of the blades will cause an instantaneous vacuum to be formed inside the vacuum cleaner 16, forming a negative pressure difference with the external atmospheric pressure. Under the action of the negative pressure difference, the dirt outside the vacuum cleaner 16 will be sucked into the collection cover 19 into the collection box 15 through the pump suction hose 17, so as to avoid the secondary clogging of the filter net due to the failure to clean the dirt scraped off the filter net in time during the working process, thereby improving the filtering efficiency of the filter net.
