[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1 to 11As shown, the present invention provides a technical solution: a high-voltage power grid gas-insulated switchgear, comprising a cabinet 1, a pair of baffles 8 being symmetrically fixedly connected to the inner wall of the cabinet 1, a pair of gas cylinders 2 being symmetrically rotatably connected between the inner walls of one of the baffles 8, a pair of gas cylinders 2 3 being symmetrically rotatably connected between the inner walls of the other baffle 8, a plurality of air holes 4 being provided on the outer walls of the two gas cylinders 1 2 and the two gas cylinders 2 3, each group of the plurality of air holes 4 being respectively fitted with the side faces of the baffle 8, a suction and discharge assembly being provided above the gas cylinders 1 2 and the gas cylinders 2 3 for inhaling and releasing air, a transmission assembly for driving the gas cylinders 1 2 and the gas cylinders 2 3 for rotating being provided above the gas cylinders 1 2 and the gas cylinders 2 3, a stirring assembly for evenly mixing the gas being provided inside the two gas cylinders 2 3.

[0035] During operation: When the equipment is in use, the interior of the cabinet 1 contains a variety of electrical equipment such as circuit breakers, busbars, transformers, grounding switches, surge arresters, etc., and the operation of these electrical equipment is protected by sulfur hexafluoride gas. When the performance of sulfur hexafluoride gas deteriorates after long-term use, the sulfur hexafluoride gas inside the cabinet 1 is replaced to ensure the stable operation of the equipment; in the initial state, the multiple air holes 4 opened on the gas cylinder 1 2 and the gas cylinder 2 3 are blocked by the shielding plate 8, and the suction and discharge component is started. When the suction and discharge component moves, it will first make the two gas cylinders 1 2 and the two gas cylinders 2 3 both Generate suction, when the two gas cylinders 1 2 generate suction, the transmission component will drive the air holes 4 on the two gas cylinders 1 2 to rotate toward the inside of the cabinet 1, and the old sulfur hexafluoride gas inside the cabinet 1 will be sucked into the inside of the two gas cylinders 1 2. Because there are multiple air holes 4 on the two gas cylinders 1 2, when the gas inside the cabinet 1 is sucked, the two gas cylinders 1 2 will rotate, and the sulfur hexafluoride gas in various areas of the cabinet 1 can be sucked into the inside of the two gas cylinders 1 2. At the same time, when the two gas cylinders 2 3 generate suction, the transmission component will drive the air holes 4 on the two gas cylinders 2 3 to rotate. The air holes 4 are all rotated toward the outside of the cabinet 1, and the two gas cylinders 2 3 suck the newly set sulfur hexafluoride gas from the outside of the cabinet 1 into the inside of the two gas cylinders 2 3. After completion, continue to start the suction and discharge component, at this time, apply pressure to the gas inside the gas cylinders 1 2 and 2 3, and cooperate with the transmission component to continue to drive the gas cylinders 1 2 and 2 3 to rotate. At this time, the gas cylinder 1 2 rotates toward the outside of the cabinet 1, and the gas cylinder 1 2 can squeeze out the old sulfur hexafluoride gas inside through the air hole 4, which is convenient for subsequent collection, and the gas cylinder 2 3 rotates toward the inside of the cabinet 1, which can It is able to evenly fill the new sulfur hexafluoride gas inside it into various areas inside the cabinet 1, ensuring that the new sulfur hexafluoride gas is evenly distributed in various areas inside the cabinet 1, improving the insulation performance of the equipment, enhancing the arc extinguishing ability, and ensuring the reliability of the equipment. In addition, during the entire process of gas cylinder 2 3 sucking and releasing gas, the stirring components inside it can move to evenly mix the sulfur hexafluoride gas filled in the gas cylinder 2 3, so that the sulfur hexafluoride gas is already in a uniform concentration when it is ejected from multiple air holes 4, further improving the concentration uniformity of the gas entering the cabinet 1.

[0036] It should be noted that a concentration sensor is provided inside the cabinet 1 for detecting the concentration of sulfur hexafluoride gas inside the cabinet 1. When the concentration drops to a level insufficient to support the operation of the entire device, the gas is automatically switched.

[0037] like Figures 8 and 9As shown, the suction and release assembly includes a dual-axis hydraulic cylinder 15, and the two output ends of the dual-axis hydraulic cylinder 15 are fixedly connected to a fixed rod 19, and the two fixed rods 19 are fixedly connected to a piston 18 at one end away from the dual-axis hydraulic cylinder 15. The top of the cabinet 1 is symmetrically fixed with an air flow cylinder 16 and an air flow cylinder 2 17, and the two pistons 18 are respectively slidably connected to the interior of the air flow cylinder 16 and the air flow cylinder 2 17. The air flow cylinder 16 and the air flow cylinder 2 17 are symmetrically fixedly connected to a connecting pipe 3 20 at one end away from the dual-axis hydraulic cylinder 15. The other ends of the two connecting pipes 3 20 fixedly connected to the air flow cylinder 16 are respectively fixedly connected to the interior of the two air cylinders 1 2, and the other ends of the two connecting pipes 3 20 fixedly connected to the ventilation box 7 are respectively fixedly connected to the interior of the two air cylinders 2 3.

[0038] When working: start the double-axis hydraulic cylinder 15, and its two output ends will drive the two pistons 18 to slide toward one side of the double-axis hydraulic cylinder 15 in the interior of the air flow cylinder 1 16 and the air flow cylinder 2 17 respectively through the fixed rod 19. When the piston 18 slides in the interior of the air flow cylinder 16, it will generate suction to the interior of the air cylinder 2 through the connecting pipe 3 20. At this time, the transmission component just drives the air cylinder 2 to rotate along the interior of the cabinet 1. The suction can make the old sulfur hexafluoride gas inside the cabinet 1 be sucked into the interior of the air cylinder 2 from the multiple air holes 4. When the piston 18 moves to the maximum distance, the air cylinder 2 just rotates half a circle, and the multiple air holes 4 just fit into one side of the baffle 8. At this time, the double-axis hydraulic cylinder 15 is used to make the piston 18 inside the air flow cylinder 16 move in the opposite direction and reset. When resetting, it is pushed to the interior of the air cylinder 2 through the connecting pipe 3 20. An extrusion pressure is generated inside the air cylinder 2. At this time, when the transmission component drives the air cylinder 2 to rotate, the air cylinder 2 will face the outside of the cabinet 1, and the gas inside the air cylinder 2 will be squeezed out for collection; similarly, when the piston 18 slides inside the air cylinder 2 17, a suction force will be generated inside the air cylinder 2 3. At this time, the transmission component just drives the air cylinder 2 3 to rotate along the outside of the cabinet 1. The suction force can make the new sulfur hexafluoride gas outside the cabinet 1 be sucked into the inside of the air cylinder 2 3 from multiple air holes 4. When the piston 18 inside the air cylinder 2 17 moves in the opposite direction and resets, an extrusion pressure is generated to the inside of the air cylinder 2 3 through the connecting pipe 3 20. At this time, the transmission component drives the air cylinder 2 3 to rotate toward the inside of the cabinet 1, and the gas sucked into the inside of the air cylinder 2 3 can be evenly sprayed from multiple air holes 4 to various areas inside the cabinet 1.

[0039] like Figures 8 and 9 As shown, the dual-axis hydraulic cylinder 15 is fixedly installed on the top of the cabinet 1, the air flow cylinder 16 and the air flow cylinder 2 17 are fixedly installed on the top of the cabinet 1, and a ventilation box 7 is provided on one side of the two air cylinders 1 2 and the two air cylinders 2 3. The two sides of the ventilation box 7 are fitted with one side of the baffle 8, and the outer side of the ventilation box 7 is fitted with the outer wall of the air cylinder 1 2 and the air cylinder 2 3 respectively. The ventilation box 7 is fixedly connected to one side of the cabinet 1.

[0040] During operation: through the provided ventilation box 7, when the air cylinder 2 3 is inhaling and rotating toward the outside of the cabinet 1, the multiple air holes 4 opened on its outer wall will always face the inside of the ventilation box 7, and new sulfur hexafluoride gas can enter the inside of the air cylinder 2 3 through the ventilation box 7; when the air cylinder 1 2 is deflating and rotating toward the outside of the cabinet 1, the multiple air holes 4 opened on its outer wall will always face the inside of the ventilation box 7, and the old sulfur hexafluoride gas can be discharged from the inside of the air cylinder 1 2 through the ventilation box 7, thereby achieving the effect of recycling and collecting the old sulfur hexafluoride gas, which is convenient for its further processing and utilization.

[0041] like Figures 2 to 3 As shown, one side of the ventilation box 7 is fixedly connected with multiple connecting pipes 19, one end of the multiple connecting pipes 19 is fixedly connected with an air distributor 10, one end of the multiple air distributors 10 is fixedly connected with a connecting pipe 2 13, and a one-way valve 14 is provided on the outside of each connecting pipe 2 13. The end of the connecting pipe 2 13 close to the air cylinder 12 and away from the air distributor 10 is fixedly connected with an air storage box 11, and the end of the connecting pipe 2 13 close to the air cylinder 2 3 and away from the air distributor 10 is fixedly connected with an air storage box 2 12.

[0042] During operation: When the gas inside the cabinet 1 needs to be replaced, the gas storage box 11 is connected to the connecting pipe 2 13 near one end of the gas cylinder 1 2, and the gas storage box 2 12 is connected to the connecting pipe 2 13 near one end of the gas cylinder 2 3. The interior of the gas storage box 11 is empty, and the interior of the gas storage box 2 12 is filled with new sulfur hexafluoride gas. When the gas cylinder 2 3 is inhaling and rotating toward the outside of the cabinet 1, the multiple air holes 4 will always face the inside of the ventilation box 7. The suction force generated at this time will evenly pass the new sulfur hexafluoride gas inside the gas storage box 2 12 through the connecting pipe 2 13. The gas distributor 10 and the connecting pipe 9 are sucked into the interior of the gas cylinder 2 3. When the gas cylinder 2 is deflated and rotated toward the outside of the cabinet 1, the multiple air holes 4 will always face the interior of the ventilation box 7. Under the action of the extrusion force, the old sulfur hexafluoride gas can pass through the ventilation box 7, the connecting pipe 9 and the gas distributor 10 into the interior of the gas storage box 11 for collection. The one-way valve 14 is set to prevent the new sulfur hexafluoride gas in the gas storage box 2 12 from flowing back after being sucked away, and the old sulfur hexafluoride gas in the gas storage box 11 from flowing back after entering.

[0043] like Figure 4 and Figure 10 As shown, both ends of the two air cylinders 1 2 and the two air cylinders 2 3 are fixedly connected with a blocking plate 5, the top of the blocking plate 5 is fixedly connected with a hollow rotating rod 6, the outer wall of each hollow rotating rod 6 is fixedly connected with a transmission belt 32, and the outer walls of each two transmission belts 32 are connected with a transmission ring 2 33.

[0044] During operation: When the suction and discharge component causes air cylinder 1 2 and air cylinder 2 3 to inhale and deflate twice, the transmission ring 2 33 will be driven by the transmission component for transmission. The transmission ring 2 33 will drive the adjacent air cylinder 1 2 and air cylinder 2 3 to rotate through the transmission belt 32 and the hollow rotating rod 6, so that the two air cylinders 1 2 and air cylinder 2 3 on the same side rotate in the same direction, so that when air cylinder 1 2 inhales old air toward the inside of the cabinet 1, air cylinder 2 3 inhales new air toward the outside of the cabinet 1, and when air cylinder 1 2 releases old air toward the outside of the cabinet 1, air cylinder 2 3 releases new air toward the inside of the cabinet 1.

[0045] like Figures 10 and 11 As shown, the transmission assembly includes a connecting member 21, which is fixedly installed on the outer wall of one of the fixed rods 19. The top of the connecting member 21 is fixedly connected to an inner slider 22, and both sides of the inner slider 22 are fixedly connected to connecting rods 24. One end of the connecting rod 24 is hinged to a hinged rod 25, and the end of the hinged rod 25 away from the connecting rod 24 is hinged to an eccentric rod 28, and one end of the eccentric rod 28 is fixedly connected to an elliptical block 26.

[0046] During operation: when the fixed rod 19 drives the piston 18 to move for inhalation, it will drive the inner slider 22 to move through the connecting piece 21, and the inner slider 22 will drive the connecting rod 24 to move. The connecting rod 24 will make the elliptical block 26 rotate half a circle through the hinged rod 25 and the eccentric rod 28, and when the fixed rod 19 drives the piston 18 to move in the opposite direction and reset to deflate, it can drive the elliptical block 26 to continue to rotate half a circle in the same direction just now, so that each time the piston 18 moves back and forth so that the air cylinder 1 2 and the air cylinder 2 3 complete the suction and deflation, the elliptical block 26 can just rotate one circle.

[0047] like Figures 9 to 11 As shown, a fixing seat 23 is fixedly installed on the top of the cabinet 1, and the inner slider 22 is slidably connected to the inner wall of the fixing seat 23. The inner wall length of the air flow tube 16 is the same as the inner groove length of the fixing seat 23, and the inner groove length of the fixing seat 23 is the same as the length of the elliptical block 26.

[0048] During operation: the stability of the inner slider 22 during the sliding process is improved by setting the fixed seat 23, and since the inner wall length of the air flow cylinder 16 is the same as the inner groove length of the fixed seat 23, the inner groove length of the fixed seat 23 is the same as the length of the elliptical block 26, the elliptical block 26 can rotate just half a circle after the piston 18 moves once, and the elliptical block 26 continues to rotate half a circle during the second reverse reset movement.

[0049] like Figures 10 and 11As shown, a rotating rod 27 is fixedly connected to the center of the back side of the elliptical block 26, and a clamping member is rotatably connected to the outer wall of the rotating rod 27. The clamping member is fixedly installed on the top of the cabinet 1, and the end of the rotating rod 27 away from the elliptical block 26 is fixedly connected to a driving gear 29. The teeth of the driving gear 29 are engaged with a driven gear 30. The shaft of the driven gear 30 is fixedly connected to a transmission ring 1 31. The outer wall of the transmission ring 1 31 is transmission-connected to the inner wall of the transmission ring 2 33.

[0050] During operation: When the elliptical block 26 rotates, the driving gear 29 is driven to rotate through the rotating rod 27, and the driving gear 29 drives the transmission ring 1 31 to rotate through the driven gear 30, and the transmission ring 1 31 drives the transmission belt 32 to rotate, so that the transmission belt 32 drives the air cylinder 1 2 and the air cylinder 2 3 to rotate through the transmission ring 2 33, and when the elliptical block 26 rotates half a circle, the air cylinder 1 2 and the air cylinder 2 3 also rotate half a circle.

[0051] like Figure 5 and Figure 7 As shown, the stirring assembly includes two groups of stirring rods 36, each group of stirring rods 36 has two stirring rods 36 and they are respectively located inside the air cylinder 2 3, and the two ends of the stirring rods 36 are respectively rotatably connected to the two blocking plates 5, and the outer wall of each stirring rod 36 is fixedly connected to a plurality of stirring blades 37.

[0052] During operation: the gas cylinder 2 3 will rotate when inhaling and deflating, and the stirring blade 37 and the stirring rod 36 will also rotate inside the gas cylinder 2 3. When the stirring rod 36 rotates, the gas entering the inner cavity of the gas cylinder 2 3 can be evenly mixed and stirred, avoiding local concentration differences in the gas entering the gas cylinder 2 3, which would affect the uniform entry of the gas into the interior of the cabinet 1.

[0053] like Figure 5 and Figure 7 As shown, the interior of the two air cylinders 2 3 is provided with an internal gear plate 34, which is rotationally connected to the blocking plate 5, and the teeth of the internal gear plate 34 are symmetrically meshed with the internal gear 35, which is fixedly connected to the outer wall of the stirring rod 36.

[0054] During operation: When the blocking plate 5 drives the stirring rod 36 to rotate inside the gas cylinder 2 3, the stirring rod 36 will revolve along the inner side of the internal gear plate 34, and when the stirring rod 36 revolves, the teeth of the internal gear 35 will engage with the teeth of the internal gear plate 34. Therefore, when the stirring rod 36 revolves, it will also rotate on its own. Therefore, the stirring rod 36 further improves the effect of stirring the gas under the action of the revolution and rotation inside the gas cylinder 2 3.
