Description

Technical Field

[0001] The invention relates to the technical field of gas-insulated switchgear, in particular to an environmentally friendly gas-insulated switch cabinet utilizing nylon-sealed poles. Background Art

[0002] Nylon sealed pole refers to an independent component consisting of a vacuum interrupter, or a vacuum interrupter, a conductive connection or a terminal encapsulated with nylon insulating material. Compared with the traditional assembled pole, the number of parts of the sealed pole is greatly reduced, the conductor overlap is reduced from 6 groups to 3 groups, and the connecting bolts are reduced from 8 to 1-3. The simple structure greatly improves the reliability of the circuit breaker. Compared with the traditional oil-immersed or gas-insulated switchgear, the gas-insulated switchgear with nylon sealed pole reduces the impact on the environment, especially avoids the leakage and pollution of harmful gases, and can effectively prevent accidents such as arcs and short circuits, thereby improving the overall safety of the equipment.

[0003] At present, some switch cabinets with nylon sealed poles are used on outdoor construction sites. Since the heat generated by the switch cabinets with nylon sealed poles is greater than that of ordinary switch cabinets, in order to facilitate heat dissipation, the staff will directly fix the switch cabinets with nylon sealed poles in the external environment for use. When it snows, snow will accumulate on the top of the switch cabinet. Long-term snow accumulation will bring greater pressure to the switch cabinet as a whole, thereby shortening its service life. In addition, snow will also accumulate on the doors of the switch cabinets, making it difficult to open the bottom door, which is inconvenient for staff to inspect. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-8 The present invention provides a technical solution: an environmentally friendly gas-insulated switchgear using nylon-sealed poles, comprising a cabinet 1, on which a push plate 2, a first driving mechanism 3, a traction plate 4, a second driving mechanism 6 and a traction mechanism 7 are arranged, the push plate 2 is attached to the cabinet door of the cabinet 1, the first driving mechanism 3 movably sets the push plate 2 on the surface of the cabinet 1 to drive the push plate 2 to perform horizontal reciprocating motion to push away the snow accumulated on the cabinet door of the cabinet 1, the traction plate 4 is horizontally movably set on the top of the cabinet 1, and the bottom of the traction plate 4 is integrally formed with a conical protrusion 5 that contacts the top of the cabinet 1, the second driving mechanism 6 movably sets the traction plate 4 on the top of the cabinet 1 to drive the conical protrusion 5 to perform horizontal reciprocating motion to sweep away the snow accumulated on the top of the cabinet 1, and the traction mechanism 7 connects the first driving mechanism 3 and the second driving mechanism 6 to achieve synchronous action of the first driving mechanism 3 and the second driving mechanism 6.

[0044] See also Figure 1 , 2 And 3, in this embodiment, the traction mechanism 7 drives the first driving mechanism 3 and the second driving mechanism 6 to act synchronously, so that the first driving mechanism 3 drives the push plate 2 to push away the snow accumulated near the bottom door of the cabinet 1, and at the same time the second driving mechanism 6 drives the conical protrusion 5 to translate horizontally on the top of the cabinet 1 to clean the top of the cabinet 1.

[0045] Specifically, the first driving mechanism 3 includes a first rotating shaft 31, a first connecting arm 32, a second connecting arm 33 and a first limiting member 34. The first rotating shaft 31 is rotatably arranged on the side of the cabinet 1, one end of the first connecting arm 32 is fixed to the surface of the first rotating shaft 31, one end of the second connecting arm 33 is elastically connected to the first connecting arm 32, and the other end of the second connecting arm 33 is hinged to the surface of the push plate 2. The push plate 2 and the cabinet 1 are horizontally limited by the first limiting member 34.

[0046] See also Figure 1 , 2The first connecting arm 32 drives the second connecting arm 33 to swing, and the second connecting arm 33 drives the push plate 2 to perform horizontal reciprocating motion under the restriction of the first limit member 34, so as to push away the snow near the bottom door of the cabinet 1 through the push plate 2. In the process of the push plate 2 moving away from the cabinet 1, the straight-line distance from the connection between the surface of the push plate 2 and the second connecting arm 33 to the first rotating shaft 31 will gradually increase during the movement, so the overall length of the first connecting arm 32 and the second connecting arm 33 will also increase, and the push plate 2 is only affected by the rotational force of the first connecting arm 32 during the movement, but the push plate 2 needs to overcome the resistance of the snow during the movement, which requires sufficient power for the traction mechanism 7. Since the first connecting arm 32 and the second connecting arm 33 are elastically movable, in this embodiment, a spring is arranged inside the first connecting arm 32 and the second connecting arm 33. In the initial state, the spring is in a compressed energy storage state. Therefore, in the process of the push plate 2 gradually moving away from the cabinet 1, the spring gradually releases energy, and the energy released by the spring can be used by the push plate 2 to push the snow, so as to facilitate the normal operation of the overall mechanism.

[0047] Among them, the first limiting member 34 includes a limiting plate 341, a limiting groove 342 and a track 343, the track 343 is arranged on the side of the cabinet 1, the limiting groove 342 is arranged on the surface of the limiting plate 341, the limiting plate 341 is vertically fixed to the surface of the push plate 2, and the limiting plate 341 slides on the surface of the track 343 through the limiting groove 342.

[0048] See also Figure 3 and 6 When the push plate 2 moves, it can drive the limiting plate 341 to move synchronously, and the limiting plate 341 can drive the limiting groove 342 to move synchronously on the surface of the track 343, thereby limiting the movement process of the push plate 2.

[0049] Specifically, the second driving mechanism 6 includes a second rotating shaft 61, a third connecting arm 62, a fourth connecting arm 63, a connecting seat 64 and a second limiting member 65. The second rotating shaft 61 is rotatably set on the surface of the cabinet 1, one end of the third connecting arm 62 is elastically movably set inside the fourth connecting arm 63, and the two connecting seats 64 are respectively fixed to one end of the third connecting arm 62 and one end of the fourth connecting arm 63. One of the connecting seats 64 is fixed to the surface of the second rotating shaft 61, and the other connecting seat 64 is connected to the traction plate 4 through the second limiting member 65.

[0050] See also Figure 1 , 2and 4, the second rotating shaft 61 can drive the third connecting arm 62 to rotate through the connecting seat 64, and the third connecting arm 62 can drive the fourth connecting arm 63 to rotate synchronously, so that the first connecting arm 32 drives the traction plate 4 to move. In the above process, the movement trajectory of the traction plate 4 should be arc-shaped, but because the top of the cabinet 1 is a plane, the movement trajectory of the traction plate 4 is limited to the horizontal plane through the second limit member 65 in this embodiment, and the overall length between the third connecting arm 62 and the fourth connecting arm 63 needs to be adjusted to dynamic, so a spring is set between the third connecting arm 62 and the fourth connecting arm 63 in this embodiment.

[0051] Among them, the second limiting member 65 includes a protective plate 651, a slide groove 652 and a connecting shaft 653, the protective plate 651 is fixed to the side of the cabinet 1, the connecting shaft 653 is fixed to the side of the traction plate 4, the slide groove 652 is arranged on the surface of the protective plate 651, one end of the connecting shaft 653 is slidably arranged in the slide groove 652, and one end of the connecting shaft 653 is rotatably connected to one of the connecting seats 64.

[0052] See also Figure 1 and 7 Through the arrangement of the slide groove 652 and the connecting shaft 653, the connecting shaft 653 can only perform horizontal reciprocating motion inside the slide groove 652, and then drive the traction plate 4 to perform synchronous horizontal reciprocating motion through the connecting shaft 653.

[0053] Specifically, the traction mechanism 7 includes a first gear 71, a second gear 72, a first rack 73, a second rack 74, a motor 75, a traction seat 76, a through groove 77, a swing arm 78 and a drive shaft 79. The motor 75 is fixed to the surface of the protective plate 651, one end of the swing arm 78 is connected to the output shaft of the motor 75, the first rack 73 and the second rack 74 are fixed to the two ends of the traction seat 76, the through groove 77 is arranged on the surface of the traction seat 76, one end of the drive shaft 79 is fixed to the other end of the swing arm 78, and the drive shaft 79 is slidably arranged in the through groove 77, the first gear 71 is fixed to the surface of the first rotating shaft 31, the second gear 72 is fixed to the surface of the second rotating shaft 61, the first gear 71 is meshed with the first rack 73, and the second gear 72 is meshed with the second rack 74.

[0054] See also Figure 1 , 2, 4, 5 and 6, the motor 75 drives the swing arm 78 to rotate, and the swing arm 78 can drive the driving shaft 79 to revolve. When the driving shaft 79 revolves, it can drive the traction seat 76 to perform horizontal reciprocating motion through the slide groove 652, so that the traction seat 76 simultaneously drives the first rack 73 and the second rack 74 to perform synchronous horizontal reciprocating motion. In the initial state, the second gear 72 is located in the middle section of the second rack 74, and the first gear 71 is located at one end of the first rack 73. When the traction seat 76 moves, it will first move to the left to the maximum stroke, and then move to the right to the maximum stroke. In this process, the second gear 72 can drive the second rack 74 to move a complete reciprocating formation, so that the traction plate 4 drives the conical protrusion 5 to sweep the snow on the top of the cabinet 1, so as to Figure 6 For example, the first rack 73 can drive the first gear 71 to reciprocate, so that the first gear 71 can drive the first rotating shaft 31 to reciprocate, thereby realizing the horizontal reciprocating motion of the push plate 2.

[0055] The surfaces of the first rack 73 and the second rack 74 are both provided with T-shaped slots 8 , and the side of the cabinet 1 is provided with T-shaped protrusions 9 . The first rack 73 and the second rack 74 are slidably provided on the surface of the T-shaped protrusions 9 through the T-shaped slots 8 .

[0056] See also Figure 8 By the cooperation of the T-shaped protrusion 9 and the T-shaped groove 8, the first rack 73 and the second rack 74 can be restricted to the side of the cabinet 1 so that they can only perform horizontal reciprocating motion.

[0057] Specifically, a first guide rod 10 and a second guide rod 11 are respectively fixed to both sides of the traction plate 4 , and a first arc-shaped protrusion 12 and a second arc-shaped protrusion 13 are respectively provided on the surface of the protection plate 651 .

[0058] See also Figure 7 In the initial state, the first guide rod 10 is in contact with the protective plate 651, but the second guide rod 11 is not in contact with the protective plate 651, and the distance from the second guide rod 11 to the protective plate 651 is exactly the same as the width of the first arc-shaped protrusion 12 and the second arc-shaped protrusion 13. When the traction plate 4 moves, it can drive the first guide rod 10 and the second guide rod 11 to move synchronously. At this time, the first guide rod 10 first contacts the first arc-shaped protrusion 12, and the first arc-shaped protrusion 12 can squeeze the traction plate 4 through the first guide rod 10, so that the traction plate 4 moves horizontally. When the first guide rod 10 is separated from the surface of the first arc-shaped protrusion 12, the second guide rod 11 is exactly in contact with the second arc-shaped protrusion 13. At this time, the traction plate 4 continues to move, and the second arc-shaped protrusion 13 can squeeze the traction plate 4 to move horizontally in the opposite direction through the second guide rod 11 to reset it horizontally. With the movement of the traction plate 4, the above process is repeated, and the traction plate 4 can drive the conical protrusion 5 to perform a horizontal reciprocating motion horizontally, thereby scraping off the snow frozen on the top of the cabinet 1.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
