Description

Technical Field

[0001] This invention relates to the field of gas ring main unit sealing structure equipment technology, specifically an environmentally friendly gas ring main unit sealing structure. Background Technology

[0002] Environmentally friendly gas ring main units are a new type of high-voltage switchgear that uses protective insulating gas instead of traditional sulfur hexafluoride gas. They are mainly used in ring power supply systems of urban power distribution networks. With the increasing global emphasis on environmental protection and greenhouse gas emission reduction, environmentally friendly gas ring main units are gradually becoming an important direction for upgrading power distribution network equipment due to their low-carbon and environmentally friendly characteristics.

[0003] In existing technologies, when sealing ring main units, sealing is usually achieved through a sealing door. Since the sealing door is in contact with the inside of the cabinet, wear and tear will occur during the opening and closing of the sealing door and the cabinet. Over time, this will reduce the sealing effect of the sealing door and lead to gas leakage. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly gas ring main unit sealing structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0010] Furthermore, the surface of the sealing door is hinged to the surface of the ring main unit, and mounting grooves are provided on both sides of the inner wall of the ring main unit, and grooves are provided on the upper surface of both sides of the inner wall of the ring main unit.

[0011] Furthermore, the sealing mechanism includes a grooved plate, a slide is slidably connected to the inner wall of the grooved plate, a contact plate is fixedly connected to the end of the slide, a limiting elastic rod is fixedly connected to the end of the slide away from the contact plate, elastic plates are fixedly connected to both sides of the slide, and an expansion rod is hinged to the surface of the elastic plate.

[0012] Furthermore, the top of the grooved plate is fixedly connected to the top of the inner wall of the ring main unit, the surface of the slider is slidably connected to the inner wall of the groove, and the end of the expansion rod away from the elastic plate is hinged to the end of the slider.

[0013] Furthermore, the reinforcement mechanism includes a U-shaped support plate, a driven plate fixedly connected to the top of the U-shaped support plate, sliding groove plates fixedly connected to both ends of the U-shaped support plate, and a lower reinforcement plate fixedly connected to the bottom of the sliding groove plate.

[0014] Furthermore, the end of the driven plate away from the U-shaped support plate is fixedly connected to the surface of the push telescopic rod, the end of the reinforcing plate away from the reinforcing contact plate is slidably connected to the inner wall of the slide plate, and the end of the supporting elastic rod away from the reinforcing contact plate is fixedly connected to the surface of the U-shaped support plate.

[0015] Furthermore, the stabilizing mechanism includes a curved rod, the end of which is fixedly connected to a right-angle elastic rod, the end of which is fixedly connected to a stabilizing plate, and a moving groove is provided on the top of the inner wall of the ring main unit.

[0016] Furthermore, the end of the curved rod away from the right-angle elastic rod is fixedly connected to the surface of the U-shaped support plate, the surface of the right-angle elastic rod is slidably connected to the inner wall of the moving groove, the end of the right-angle elastic rod away from the stabilizing plate is fixedly connected to the surface of the moving slide plate, and the end of the limiting spring away from the moving slide plate is fixedly connected to the inner wall of the moving groove.

[0017] The present invention has the following beneficial effects:

[0018] This invention employs a sealing mechanism. First, a power unit pulls a lever to move closer together. As the lever moves, it pulls the sealing door to close, causing it to shut. During this closing process, the sealing door contacts the end of a contact plate, pushing the contact plate closer together. As the contact plate moves, it pushes a slide along the inner wall of a grooved plate closer together. This sliding motion pushes a limiting elastic rod to retract closer together. When the limiting elastic rod retracts to a certain position, it limits the slide, preventing contact between the two slides. Simultaneously, the sliding motion causes the end of an elastic plate to move closer together. During this movement, the middle section of the elastic plate bends, pushing the end of an expansion rod away from each other. The other end of the expansion rod pushes the slider to slide away from each other on the inner wall of the groove. As the slider slides, it pushes the telescopic rod to move away from each other. As the telescopic rod moves, it pushes the sealing frame to move closer together. When the sealing frame is in place, it is at the contact position between the sealing door and the inner wall of the ring main unit, thus sealing. When the sealing frame is in place, the slider is also pushed by the expansion rod to move the telescopic rod away from each other. At this time, the telescopic rod is limited by the sealing frame, causing it to contract away from each other, making the sealing frame fit more tightly. This effectively prevents air leakage at the contact position between the sealing door and the inner wall of the ring main unit, and also prevents wear and leakage caused by the opening and closing of the cabinet door.

[0019] This invention employs a reinforcement mechanism. When the telescopic rod is moved, the driven plate moves away from each other. The movement of the driven plate causes the U-shaped support plate to move away from each other. The movement of the U-shaped support plate then causes the sliding plate and the supporting elastic rod to move away from each other. The movement of the sliding plate causes the reinforcement plate to move away from each other. The movement of the supporting elastic rod causes the reinforcement contact plate to move away from each other. Simultaneously, the movement of the sliding plate causes the lower reinforcement plate to move away from each other. During the movement of the reinforcement contact plate, it comes into contact with the surface of the sealing frame. Once in contact with the sealing frame, the reinforcement contact plate remains stationary and limits the movement of the supporting elastic rod. The U-shaped support plate will continue to drive the support elastic rods to retract in a direction away from each other. During the retraction of the support elastic rods, the angle between the reinforcing plate and the reinforcing contact plate will change. At the same time, the end of the reinforcing plate will slide in a direction away from each other on the inner wall of the sliding plate. When the reinforcing plate slides into place, the reinforcing contact plate and the reinforcing plate will be on the same horizontal line and in contact with the surface of the sealing frame. At the same time, the lower reinforcing plate will contact the lower surface of the sealing frame, thereby reinforcing the sealing frame. The sealing frame is effectively reinforced by the reinforcing plate, the reinforcing contact plate and the lower reinforcing plate, so that the sealing frame fits more tightly with the sealing door and the ring main unit, and at the same time, it prevents the sealing frame from loosening over time.

[0020] This invention employs a stabilizing mechanism. As the U-shaped support plate moves, it causes the curved rod to move in a direction away from each other. This movement of the curved rod, in turn, causes the right-angle elastic rod to move in the same direction. The right-angle elastic rod, in turn, causes the sliding plate to slide along the inner wall of the moving groove in a direction away from each other. The sliding plate's movement compresses the moving groove, causing it to contract in a direction away from each other. Simultaneously, the right-angle elastic rod's movement pushes the stabilizing plate in a direction away from each other. When the stabilizing plate is in position, it contacts the upper surface of the sealing frame, thus stabilizing the upper surface of the sealing frame. This effectively stabilizes the upper surface of the sealing frame, and combined with the overall reinforcement mechanism, provides overall stability to the sealing frame.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8As shown, the present invention is an environmentally friendly gas ring network cabinet sealing structure, including a ring network cabinet 1, a power device 2 fixedly connected to the top of the ring network cabinet 1, a pull rod 3 fixedly connected to the output end of the power device 2, and a sealing door 4 rotatably connected to the end of the pull rod 3 away from the power device 2, and also includes;

[0035] The sealing mechanism 10 includes a slider 17. When the slider 17 slides, it pushes the telescopic rod 18 to move away from each other. The end of the slider 17 is fixedly connected to the telescopic rod 18. The end of the telescopic rod 18 away from the slider 17 is fixedly connected to a sealing frame 19. When the telescopic rod 18 moves, it pushes the sealing frame 19 to move closer to each other. When the sealing frame 19 moves into place, it will be located at the contact position between the sealing door 4 and the inner wall of the ring main unit 1, thereby sealing.

[0036] The reinforcement mechanism 30 includes a reinforcement plate 34. When the slide plate 33 moves, it will drive the reinforcement plate 34 to move in a direction away from each other. The end of the reinforcement plate 34 is hinged to a reinforcement contact plate 35. When the support elastic rod 36 moves, it will push the reinforcement contact plate 35 to move in a direction away from each other. The surface of the reinforcement contact plate 35 is fixedly connected to the support elastic rod 36.

[0037] The stabilizing mechanism 50 includes five movable slide plates 53. When the right-angle elastic rod 52 moves, it will drive the movable slide plates 53 to slide in a direction away from each other on the inner wall of the moving groove 56. The end of the movable slide plate 53 is fixedly connected to a limit spring 55.

[0038] The surface of the sealing door 4 is hinged to the surface of the ring main unit 1. The inner walls of the ring main unit 1 have mounting grooves on both sides and grooves on the upper surface of both sides of the inner walls of the ring main unit 1.

[0039] The sealing mechanism 10 includes a grooved plate 11, and a slide 12 is slidably connected to the inner wall of the grooved plate 11. When the contact plate 13 moves, it pushes the slide 12 to slide in a direction closer to each other on the inner wall of the grooved plate 11. The end of the slide 12 is fixedly connected to the contact plate 13. First, the power device 2 is started to pull the pull rod 3 to move in a direction closer to each other. When the pull rod 3 moves, it pulls the sealing door 4 to close in a direction closer to each other, thereby closing the sealing door 4. During the closing process, the sealing door 4 will contact the end of the contact plate 13 and push the contact plate 13 to move in a direction closer to each other. The end of the slide 12 away from the contact plate 13 is fixedly connected to a limiting elastic rod 14. When the slide 12 slides, it pushes the limiting elastic rod 14 to retract in a direction closer to each other. When the limiting elastic rod 14 retracts to a certain position, it will limit the slide 12, thereby preventing the two slides 12 from contacting each other. Elastic plates 15 are fixedly connected to both sides of the slide 12, and an expansion rod 16 is hinged to the surface of the elastic plate 15.

[0040] The top of the groove plate 11 is fixedly connected to the top of the inner wall of the ring main unit 1. The surface of the slider 17 is slidably connected to the inner wall of the groove. The end of the expansion rod 16 away from the elastic plate 15 is hinged to the end of the slider 17. As the slide 12 slides, it will drive the end of the elastic plate 15 to move towards each other. When the elastic plate 15 moves, the middle part will bend. When the middle part of the elastic plate 15 bends, it will push the end of the expansion rod 16 to move away from each other. The other end of the expansion rod 16 will push the slider 17 towards the inner wall of the groove. Sliding in the direction of mutual separation, when the sealing frame 19 is in place, the slider 17 will also be pushed by the expansion rod 16 to push the telescopic rod 18 to move in the direction of mutual separation. At this time, the pushing telescopic rod 18 will be limited by the sealing frame 19, so that the pushing telescopic rod 18 will retract in the direction of mutual separation, making the sealing frame 19 fit more tightly. Through the sealing of the sealing frame 19, the air leakage at the contact point between the sealing door 4 and the inner wall of the ring network cabinet 1 is effectively prevented. At the same time, it also prevents wear and leakage caused by the opening and closing of the cabinet door.

[0041] The reinforcement mechanism 30 includes a U-shaped support plate 31. A driven plate 32 is fixedly connected to the top of the U-shaped support plate 31. When the telescopic rod 18 is pushed to move, the driven plate 32 will move away from each other. When the driven plate 32 moves, it will drive the U-shaped support plate 31 to move away from each other. Slide plates 33 are fixedly connected to both ends of the U-shaped support plate 31. During the retraction of the support elastic rod 36, the angle between the reinforcement plate 34 and the reinforcement contact plate 35 will change. At the same time, the end of the reinforcement plate 34 will slide away from each other on the inner wall of the slide plate 33. A lower reinforcement plate 37 is fixedly connected to the bottom of the slide plate 33. When the slide plate 33 moves, it will drive the lower reinforcement plate 37 to move away from each other. The fixed plate 37 moves away from each other. When the U-shaped support plate 31 moves, it pushes the sliding plate 33 and the support elastic rod 36 to move away from each other. When the reinforcing plate 34 slides into place, the reinforcing contact plate 35 and the reinforcing plate 34 are on the same horizontal line and in contact with the surface of the sealing frame 19. At the same time, the lower reinforcing plate 37 is in contact with the lower surface of the sealing frame 19, thereby reinforcing the sealing frame 19. The sealing frame 19 is effectively reinforced by the reinforcing plate 34, the reinforcing contact plate 35 and the lower reinforcing plate 37, so that the sealing frame 19 is more tightly fitted to the sealing door 4 and the ring network cabinet 1, and at the same time, it prevents the sealing frame 19 from loosening after a long period of use.

[0042] The end of the driven plate 32 away from the U-shaped support plate 31 is fixedly connected to the surface of the push telescopic rod 18. The end of the reinforcing plate 34 away from the reinforcing contact plate 35 is slidably connected to the inner wall of the slide plate 33. During the movement of the reinforcing contact plate 35, it will contact the surface of the sealing frame 19. The end of the supporting elastic rod 36 away from the reinforcing contact plate 35 is fixedly connected to the surface of the U-shaped support plate 31. When the reinforcing contact plate 35 contacts the sealing frame 19, it will remain stationary and limit the supporting elastic rod 36. At this time, the U-shaped support plate 31 will continue to drive the supporting elastic rod 36 to retract in the direction away from each other.

[0043] The stabilizing mechanism 50 includes a curved rod 51. When the U-shaped support plate 31 moves, it drives the curved rod 51 to move away from each other. A right-angle elastic rod 52 is fixedly connected to the end of the curved rod 51. When the curved rod 51 moves, it drives the right-angle elastic rod 52 to move away from each other. When the right-angle elastic rod 52 moves, it pushes the stabilizing plate 54 to move away from each other. The end of the right-angle elastic rod 52 is fixedly connected to the stabilizing plate 54. A moving groove 56 is provided on the top of the inner wall of the ring main unit 1. When the moving slide plate 53 moves, it will squeeze the moving groove 56. When the moving groove 56 is squeezed, it will contract away from each other. When the stabilizing plate 54 moves into place, the stabilizing plate 54 will contact the upper surface of the sealing frame 19, thereby stabilizing the upper surface of the sealing frame 19. The stabilizing plate 54 effectively stabilizes the upper surface of the sealing frame 19. Combined with the reinforcement mechanism 30, the sealing frame 19 is stabilized as a whole.

[0044] The end of the curved rod 51 away from the right-angle elastic rod 52 is fixedly connected to the surface of the U-shaped support plate 31. The surface of the right-angle elastic rod 52 is slidably connected to the inner wall of the moving groove 56. The end of the right-angle elastic rod 52 away from the stabilizing plate 54 is fixedly connected to the surface of the moving slide plate 53. The end of the limiting spring 55 away from the moving slide plate 53 is fixedly connected to the inner wall of the moving groove 56.

[0045] In use, first, start the power unit 2 and pull the lever 3 to move them closer together. As the lever 3 moves, it pulls the sealing door 4 to close, thus closing the sealing door 4. During the closing process, the sealing door 4 contacts the end of the contact plate 13 and pushes the contact plate 13 to move closer together. When the contact plate 13 moves, it pushes the slide 12 to slide closer together on the inner wall of the groove plate 11. As the slide 12 slides, it pushes the limiting elastic rod 14 to retract closer together. When the limiting elastic rod 14 retracts to a certain position, it limits the slide 12, thus preventing the two slides 12 from contacting each other. Simultaneously, the sliding of the slide 12 drives the end of the elastic plate 15 to move closer together. When the elastic plate 15 moves, its middle part bends. This bending pushes the end of the expansion rod 16 away from each other. The other end of the expansion rod 16 pushes the slider 17 to slide away from each other on the inner wall of the groove. As the slider 17 slides, it pushes the telescopic rod 18 away from each other. This movement of the telescopic rod 18 pushes the sealing frame 19 towards each other. When the sealing frame 19 is in place, it is positioned at the contact point between the sealing door 4 and the inner wall of the ring main unit 1, thus sealing the area. When the sealing frame 19 is in place, the slider 17 is also pushed by the expansion rod 16 to move the telescopic rod 18 away from each other. The telescopic rod 18 is limited by the sealing frame 19, causing it to retract in a direction away from each other, making the sealing frame 19 fit more tightly. As the telescopic rod 18 moves, it also moves the driven plate 32 in a direction away from each other. The movement of the driven plate 32 causes the U-shaped support plate 31 to move in a direction away from each other. The movement of the U-shaped support plate 31 pushes the sliding plate 33 and the supporting elastic rod 36 in a direction away from each other. The movement of the sliding plate 33 causes the reinforcing plate 34 to move in a direction away from each other. The movement of the supporting elastic rod 36 pushes the reinforcing contact plate 35 in a direction away from each other. Simultaneously, the movement of the sliding plate 33 causes the lower reinforcing plate 37 to move in a direction away from each other. During its movement, the contact plate 35 contacts the surface of the sealing frame 19. After contacting the sealing frame 19, the reinforcing contact plate 35 remains stationary and limits the support elastic rod 36. At this time, the U-shaped support plate 31 continues to drive the support elastic rod 36 to retract in a direction away from each other. During the retraction of the support elastic rod 36, the angle between the reinforcing plate 34 and the reinforcing contact plate 35 changes. Simultaneously, the end of the reinforcing plate 34 slides away from each other on the inner wall of the slide plate 33. When the reinforcing plate 34 slides into place, the reinforcing contact plate 35 and the reinforcing plate 34 remain on the same horizontal line and contact the surface of the sealing frame 19. At the same time, the lower reinforcing plate 37 contacts the lower surface of the sealing frame 19, thereby reinforcing the sealing frame 19.As the U-shaped support plate 31 moves, it causes the curved rod 51 to move in a direction away from each other. The movement of the curved rod 51 causes the right-angle elastic rod 52 to move in a direction away from each other. The movement of the right-angle elastic rod 52 causes the sliding plate 53 to slide against the inner wall of the moving groove 56 in a direction away from each other. The moving plate 53 compresses the moving groove 56, causing it to contract in a direction away from each other. Simultaneously, the movement of the right-angle elastic rod 52 pushes the stabilizing plate 54 to move in a direction away from each other. When the stabilizing plate 54 is in position, it contacts the upper surface of the sealing frame 19, thus stabilizing the upper surface of the sealing frame 19.
