Description

Technical Field

[0002] Vacuum oil filter is a kind of equipment commonly used in the power, petroleum and other industries. It is mainly used to treat insulating oils such as transformer oil and turbine oil, and improve their cleanliness and insulation performance through filtration and degassing. During the operation of the vacuum oil filter, the adjustment of vacuum degree is very important because it directly affects the degassing efficiency and treatment quality of the oil.

[0003] Before adjusting the vacuum degree, it is necessary to conduct gas sampling and testing. By testing the gas composition and content in the separator, you can understand the current vacuum state and whether there is any abnormality. For example, if it is detected that the gas contains a large amount of moisture or impurities, it may mean that the vacuum degree is insufficient or the separation effect is poor, and corresponding adjustments need to be made.

[0004] The oil gas content sampling device specially used for vacuum oil filter in the prior art needs to shut down the vacuum oil filter when in use, and then connect the sampling pipe to the vacuum oil filter pipe.

[0037] During operation, first connect the pipes on the four vacuum oil filters to the pipe interface 30 on the bellows expansion pipe 29, and then the first servo motor 2 drives the worm 3 to rotate, the worm 3 drives the worm wheel 4 to rotate, and the worm wheel 4 drives the driving main shaft 5 connected thereto to rotate, so that the driving main shaft 5 rotates on the fixed support frame 1, and then the driving main shaft 5 drives the fixed disk 6 to rotate, so that the fixed disk 6 drives the sampling tube 7 to align with the connecting pipe 9, and then the sealing ring 82 on the sealing component seals the sampling tube 7 and the connecting pipe 9, and then the hydraulic expansion rod 241 pushes the fixing component to fix the connecting pipe 9 and the sampling tube 7. After the sampling tube 7 and the connecting pipe 9 are fixed, the solenoid valve 19 is opened to allow the oil and gas in the vacuum oil filter to enter the sampling tube 7 connected to the connecting pipe 20 through the bellows expansion pipe 29, and then the oil and gas are allowed to enter the connecting pipe 9 by the sampling tube 7, and then enter the sampling detection body 21 through the solenoid valve 19, and then sample and detect the gas content of the oil in the vacuum oil filter. After the vacuum oil filter oil gas content detection is completed, the sealing component and the fixing component loosen the sampling tube 7 and the connecting tube 9, and then the first servo motor 2 drives the driving spindle 5 to rotate through the worm 3 and worm gear 4, and then the driving spindle 5 drives the sampling tube 7 on the fixed plate 6 to rotate, and the second sampling tube 7 is connected to the connecting tube 9, and then the sealing component and the fixing component fix the connecting tube 9 and the sampling tube 7 for a second time, and the second vacuum oil filter oil gas content sampling and detection are performed.

The corrugated telescopic tube 29 is retracted as the fixed plate 6 rotates, thereby completing the sampling and detection of the gas content of the oil of multiple vacuum oil filters, greatly improving the efficiency of completing the sampling and detection of the gas content of the oil of multiple vacuum oil filters;

[0038] Through the transmission system of the first servo motor 2, the worm 3 and the worm wheel 4, the rotation and positioning of the sampling tube 7 can be accurately controlled to achieve fast and automatic switching of the sampling tube 7, thereby greatly improving the sampling and detection efficiency of the gas content of the oil of multiple vacuum oil filters; the first servo motor 2 drive and the solenoid valve 19 control of the entire system realize the automation of the steps of sampling, sealing, fixing, detection and resetting, reduce manual operations, and improve work efficiency and accuracy.

[0039] like Figure 1 , 4As shown in , 6 and 7, six clamping grooves 10 are provided on the sampling tube 7 and the connecting tube 9; a T-shape is provided in the clamping groove 10; the fixing assembly includes a connecting frame 242; two hydraulic telescopic rods 241 are installed at the bottom of the connecting frame 242; two hydraulic telescopic rods 241 are provided, and the bottoms of the two hydraulic telescopic rods 241 are fixed on the same supporting bottom plate 25; two supporting slide bars 23 are slidably connected to the connecting frame 242; the bottoms of the two supporting slide bars 23 are fixed on the same supporting bottom plate 25; a second servo motor 243 is installed on the connecting frame 242; a screw rod 244 is installed on the second servo motor 243; both ends of the screw rod 244 are rotatably connected to the connecting frame 242; two sliding connecting rods 245 are threadedly connected to the screw rod 244; three clamping blocks 246 are installed on the sliding connecting rod 245; the clamping block 246 is set to T-shape; the clamping block 246 is clamped in the clamping groove 10;

[0040] During operation, after the sampling tube 7 and the connecting tube 9 are aligned, the hydraulic telescopic rod 241 drives the connecting frame 242 to move upward on the supporting slide bar 23, so that the clamping block 246 on the connecting frame 242 is in the same horizontal plane as the clamping groove 10, and then the second servo motor 243 drives the screw rod 244 to rotate, and the screw rod 244 drives the two sliding connecting rods 245 threadedly connected thereto to approach each other, so that the sliding connecting rod 245 drives the clamping block 246 to move into the clamping groove 10, and the two clamping grooves 10 on the sampling tube 7 and the connecting tube 9 form a T-shaped clamping groove 10, and the clamping block 246 is set to a T-shape, thereby driving the clamping block 246 to clamp into the clamping groove 10, thereby fixing the sampling tube 7 and the connecting tube 9, reducing the possibility of the sampling tube 7 and the connecting tube 9 being separated during sampling. After the sampling and detection are completed, the screw rod 244 is driven to rotate. The sliding connecting rod 245 is driven to disengage the clamping block 246 from the clamping groove 10, and then the hydraulic telescopic rod 241 drives the connecting frame 242 to move downward on the supporting slide bar 23. When the second sampling tube 7 is connected to the connecting tube 9, it is raised again to fix the sampling tube 7 and the connecting tube 9; the six clamping grooves 10 and the T-shaped clamping block 246 ensure the stability of the sampling tube 7 and the connecting tube 9 after connection. This fixing method is not only simple and fast, but also can greatly reduce the risk of separation of the sampling tube 7 and the connecting tube 9 during the sampling process, thereby improving the accuracy and safety of sampling; the combination of the hydraulic telescopic rod 241 and the supporting slide bar 23 allows the connecting frame 242 to move up and down flexibly, which is convenient for aligning the clamping block 246 with the clamping groove 10, and avoiding the collision of the sampling tube 7 with the screw 244 during rotation.

[0041] like Figure 5As shown, four electric push rods 81 are installed on the sampling tube 7; the same sealing ring 82 is installed at the bottom of the electric push rod 81; a sealing groove 11 is opened on the connecting tube 9; one of the sealing rings 82 is clamped in the sealing groove 11; during operation, after the sampling tube 7 and the connecting tube 9 are aligned, the four electric push rods 81 drive the sealing ring 82 to slide downward in the sampling tube 7, so that the sealing ring 82 is clamped in the sealing groove 11 on the connecting tube 9, thereby improving the sealing between the connecting tube 9 and the sampling tube 7; the four electric push rods 81 act synchronously to ensure that the sealing ring 82 is evenly and stably clamped in the sealing groove 11 on the connecting tube 9, effectively avoiding leakage problems caused by uneven sealing or insufficient sealing force, thereby improving the overall sealing performance of the system during the sampling process.

[0042] like Figure 3 , 7 As shown in Figures 8 and 9, a connecting shaft 15 is rotatably connected to the connecting tube 9; a filter plate 12 is installed on the connecting tube 9; a pulley 13 is installed on the connecting shaft 15 and the driving main shaft 5; the same belt 14 is installed on the two pulleys 13; the connecting shaft 15 is arranged at one end of the connecting tube 9 and two fixing columns 16 are installed; six cleaning scrapers 17 and fan blades 18 are respectively installed on the two fixing columns 16; the cleaning scraper 17 is arranged above the fan blade 18, and the cleaning scraper 17 overlaps the bottom of the filter plate 12; when working, the filter plate 12 in the connecting tube 9 will filter the oil and gas entering, and when the driving main shaft 5 rotates, the driving main shaft 5 drives the pulley 13 to rotate, and the pulley 13 drives another pulley 13 to rotate through the belt 14. The other pulley 13 drives the connecting shaft 15 to rotate, so that the connecting shaft 15 drives the fixed column 16 connected thereto to rotate, and then the fixed column 16 drives the cleaning scraper 17 and the fan blade 18 to rotate, to scrape the filter plate 12, and then clean the filter plate 12. The fan blade 18 rotates to generate wind to blow to the filter plate 12 to assist in cleaning the filter plate 12. When the sampling tube 7 is replaced by the driving main shaft 5, while replacing the sampling tube 7, due to the continuous rotation of the driving main shaft 5, the cleaning scraper 17 and the fan blade 18 in the connecting tube 9 are also continuously working, thereby realizing the synchronous cleaning of the connecting tube 9; by automatically cleaning the filter plate 12, the influence of impurities on sampling detection is reduced, and the accuracy of sampling is improved; cleaning the filter plate 12 can prevent blockage and damage caused by accumulation of impurities.

[0048] S3: After the gas content of the oil in a vacuum oil filter is detected, the hydraulic telescopic rod 241 drives the fixed component to loosen the sampling tube 7 and the connecting tube 9, the solenoid valve 19 is closed, and then the first servo motor 2 drives the driving spindle 5 to rotate through the worm 3 and the worm gear 4, and then the driving spindle 5 drives the sampling tube 7 on the fixed plate 6 to rotate, and the second sampling tube 7 is connected to the connecting tube 9. After the connection is completed, the solenoid valve 19 is opened and the sampling and detection body 21 performs sampling and detection;

[0049] S4: The driving main shaft 5 drives the sampling tube 7 on the fixed plate 6 to rotate, so that when detecting the gas content of the oil liquid of multiple vacuum oil filters, there is no need to repeatedly disassemble and install the sampling tube 7 for detection. After the detection is completed, the pipeline interface 30 is separated from the vacuum oil filter pipeline, thereby completing the vacuum oil filter oil gas content sampling detection work.

[0050] Working principle: When working, first connect the pipes on the four vacuum oil filters to the pipe interface 30 on the bellows expansion pipe 29, and then the first servo motor 2 drives the worm 3 to rotate, the worm 3 drives the worm wheel 4 to rotate, and the worm wheel 4 drives the driving main shaft 5 connected thereto to rotate, so that the driving main shaft 5 rotates on the fixed support frame 1, and then the driving main shaft 5 drives the fixed disk 6 to rotate, so that the fixed disk 6 drives the sampling tube 7 to align with the connecting pipe 9, and then the sealing ring 82 on the sealing assembly seals the sampling tube 7 and the connecting pipe 9, and then the fixing assembly is pushed by the hydraulic telescopic rod 241 to fix the connecting pipe 9 and the sampling tube 7. After the sampling tube 7 and the connecting pipe 9 are fixed, the solenoid valve 19 is opened to allow the oil and gas in the vacuum oil filter to enter through the bellows expansion pipe 29 The oil gas enters the connecting pipe 9 through the sampling pipe 7, and then enters the sampling detection body 21 through the solenoid valve 19, and then samples and detects the gas content of the vacuum oil filter oil. After the first vacuum oil filter oil gas content detection is completed, the sealing component and the fixing component loosen the sampling pipe 7 and the connecting pipe 9, and then the first servo motor 2 drives the driving spindle 5 to rotate through the worm 3 and worm gear 4, and then the driving spindle 5 drives the sampling pipe 7 on the fixed plate 6 to rotate, and the second sampling pipe 7 is connected to the connecting pipe 9, and then the sealing component and the fixing component fix the connecting pipe 9 and the sampling pipe 7 for the second time, and the second vacuum oil filter oil gas content sampling and detection are carried out, and the four vacuum oil filter oil gas content are sampled and tested repeatedly. After completion, the pipeline interface 30 is separated from the vacuum oil filter pipeline, and then the first servo motor 2 drives the driving main shaft 5 to rotate in the opposite direction through the worm 3 and worm gear 4, and the fixed plate 6 and its bellows telescopic tube 29 are reset. The bellows telescopic tube 29 is telescoped as the fixed plate 6 rotates, thereby completing multiple vacuum oil filter oil liquid gas content sampling and detection work, greatly improving and completing multiple vacuum oil filter oil liquid gas content sampling and detection efficiency; during operation, after the sampling tube 7 and the connecting tube 9 are aligned, the hydraulic telescopic rod 241 drives the connecting frame 242 to move upward on the supporting slide bar 23, so that the clamping block 246 on the connecting frame 242 and the clamping groove 10 are in the same horizontal plane, and then the second servo motor 243 drives the screw rod 244 to rotate, and the screw rod 244 The two sliding connecting rods 245 threadedly connected thereto are driven to approach each other, so that the sliding connecting rod 245 drives the clamping block 246 to move into the clamping groove 10. The two clamping grooves 10 on the sampling tube 7 and the connecting tube 9 form a T-shaped clamping groove 10. The clamping block 246 is set to a T-shape, thereby driving the clamping block 246 to clamp into the clamping groove 10, thereby fixing the sampling tube 7 and the connecting tube 9, and reducing the separation of the sampling tube 7 and the connecting tube 9 during sampling. After the sampling test is completed, the screw rod 244 drives the sliding connecting rod 245 to separate the clamping block 246 from the clamping groove 10, and then the hydraulic telescopic rod 241 drives the connecting frame 242 to move downward on the supporting slide rod 23. When the second sampling tube 7 is connected to the connecting tube 9, it rises again and fixes the sampling tube 7 and the connecting tube 9;The six clamping grooves 10 and the T-shaped clamping block 246 ensure the stability of the sampling tube 7 and the connecting tube 9 after connection. This fixing method is not only simple and fast, but also can greatly reduce the risk of separation of the sampling tube 7 and the connecting tube 9 during sampling, thereby improving the accuracy and safety of sampling; the combination of the hydraulic telescopic rod 241 and the supporting slide bar 23 allows the connecting frame 242 to move up and down flexibly, making it easy to align the clamping block 246 with the clamping groove 10, and avoiding collision between the sampling tube 7 and the screw rod 244 during rotation. ;
