[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0037] Please refer to Figures 1-8 As an embodiment of the utility model, the self-opening closed air-cooled bus duct comprises a line slot 1 and a cover plate 2 arranged on the line slot 1; the line slot 1 is provided with a plurality of groups of line rows 6, and installation gaps exist between the plurality of groups of line rows 6;

[0038] The self-opening assembly is connected with the cover plate 2 and can drive the cover plate 2 to move away from the trunking 1.

[0039] The limiting assembly is arranged on the trunking 1 and can limit the action of the self-opening assembly when the cover plate 2 is attached to the trunking 1.

[0040] The self-locking assembly is connected with the limiting assembly and can limit the limiting assembly after the action of the limiting assembly.

[0041] In the embodiment, the trunking 1, the cover plate 2 and the wire bar 6 form a bus trunk main body.

[0042] Without limitation, the self-opening assembly can drive the cover plate 2 to move away from the trunking 1, so that the bus trunk is opened to facilitate the maintenance personnel to maintain the internal structure of the bus trunk.

[0043] After the maintenance is completed, the maintenance personnel applies an external force to the cover plate 2 to drive the cover plate 2 to move close to the trunking 1 through the self-opening assembly, so that the bus trunk is closed.

[0044] The limiting assembly limits the action of the self-opening assembly, so that the bus trunk cannot be opened to avoid that the self-opening assembly automatically opens the bus trunk in the daily use process, thereby causing an electric safety accident.

[0045] After the limiting assembly limits the self-opening assembly, the self-locking assembly can limit the limiting assembly to avoid that the limiting assembly reduces the limitation on the self-opening assembly after a long time of use, thereby causing an electric safety accident.

[0046] Through the cooperation of the self-opening assembly, the limiting assembly and the self-locking assembly, the bus trunk can be ensured to be in a closed state during work, and the bus trunk can be quickly opened to facilitate the maintenance personnel to maintain when maintenance is needed.

[0047] As a further scheme of the utility model, the self-opening assembly comprises a first protrusion 101 arranged on the trunking 1; the trunking 1 is rotatably provided with a first connecting rod 3 and a second connecting rod 4, and the first connecting rod 3 and the second connecting rod 4 are both rotatably arranged on the cover plate 2; a second protrusion 301 is arranged on the first connecting rod 3, and a tension spring 5 is arranged between the first protrusion 101 and the second protrusion 301.

[0048] In this embodiment, the height of the first protrusion 101 is greater than the rotation center of the first connecting rod 3 and the wire slot 1; the first connecting rod 3 and the tension spring 5 are located on different straight lines, so that the tension spring 5 always provides a pulling force to the first connecting rod 3 until the pulling force of the tension spring 5 is zero; the pulling force drives the first connecting rod 3 to rotate, thereby driving the cover plate 2 to displace, so that the cover plate 2 is away from the wire slot 1; and the first connecting rod 3 drives the second connecting rod 4 to rotate through the cover plate 2, thereby making the cover plate 2 always keep parallel to the wire slot 1.

[0049] The self-opening assembly drives the cover plate 2 to displace, so that the bus slot is in an open state; only a pushing force (always greater than the pulling force of the tension spring 5) applied on the cover plate 2 can close the cover plate 2 and the wire slot 1.

[0050] As a further scheme of the utility model, the limiting assembly comprises a sliding groove 104 opened on the wire slot 1, and a first limiting protrusion 7 is slidably embedded on the sliding groove 104; a first spring 8 is installed in the sliding groove 104, and two ends of the first spring 8 respectively abut against the first limiting protrusion 7 and the sliding groove 104; a first clamping groove 201 matched with the first limiting protrusion 7 is opened on the cover plate 2.

[0051] In this embodiment, one side of the first limiting protrusion 7 close to the cover plate 2 is an inclined surface, and the back surface is a plane. When a pushing force is applied on the cover plate 2 to make the cover plate 2 close to the wire slot 1 until the two are closely fitted, the cover plate 2 will first contact the inclined surface of the first limiting protrusion 7, the first limiting protrusion 7 will slide inward in the sliding groove 104 under the pushing of the cover plate 2, the first spring 8 will be compressed, and the first limiting protrusion 7 is in sliding contact with the cover plate 2 all the time, until the first limiting protrusion 7 is out of contact with the cover plate 2 and enters the first clamping groove 201. The first limiting protrusion 7 will slide outward in the sliding groove 104 under the elastic force of the first spring 8 until the elastic force of the first spring 8 is zero. The plane of the first limiting protrusion 7 will cooperate with the inner wall of the first clamping groove 201, thereby limiting the self-opening assembly, so that the cover plate 2 cannot be away from the wire slot 1, and the two are kept closely fitted.

[0052] As a further scheme of the utility model, a guide rail 103 is installed on the wire slot 1; an insulating plate 9 is installed on the wire row 6, and a guide groove 902 slidably embedded with the guide rail 103 is opened on the insulating plate 9; a rotating plate 102 is rotatably installed in the wire slot 1, and one end of the wire row 6 is connected with the wire slot 1.

[0053] In this embodiment, the wire row 6 has a bending part, which makes the wire row 6 have stronger shrinkability. By pulling the wire row 6 to drive the insulating plate 9 to slide on the guide rail 103, the insulating plate 9 will not tilt due to the limitation of the guide rail 103, thereby avoiding the situation that the wire rows 6 contact each other when the wire row 6 is pulled. When the wire row 6 is pulled, the included angle of the bending part will change. In order to avoid the bending parts contacting each other, when the included angle of the bending part increases or decreases to a certain angle, the bending part will contact the rotating plate 102, and at this time, the rotating plate 102 will rotate, so that the wire row 6 can still stretch and shrink.

[0054] As a further scheme of the utility model, the self-locking assembly comprises a second limiting protrusion 10 slidably installed on the wire slot 1, and a second clamping groove 701 is formed in the first limiting protrusion 7; the insulating plate 9 is provided with a connecting column 901, the connecting column 901 is provided with a second spring 11, and the other end of the second spring 11 is installed on the wire slot 1.

[0055] In this embodiment, the second limiting protrusion 10 is a trapezoid, both sides of which are inclined surfaces, and the shorter side thereof faces the connecting column 901. When the first limiting protrusion 7 cooperates with the first clamping groove 201, the connecting column 901 faces the second limiting protrusion 10 and cooperates with each other, the second limiting protrusion 10 is pushed upward by the connecting column 901 and slides upward, at this time, the second limiting protrusion 10 enters the second clamping groove 701, so that the first limiting protrusion 7 cannot be displaced, thereby locking the limiting assembly to further limit the action of the self-opening assembly.

[0056] When it is necessary to close the busbar slot, the wire row 6 is first pushed by external force to shrink into the wire slot 1, thereby driving the insulating plate 9 to slide inward, the connecting column 901 also slides inward, the second spring 11 is compressed, and the second limiting protrusion 10 slides downward under the action of gravity, at this time, the limiting assembly can smoothly act, thereby making the wire slot 1 and the cover plate 2 closely fit. Then the external force is removed, the elastic force of the second spring 11 drives the insulating plate 9 to slide outward, the connecting column 901 also slides, so that the connecting column 901 pushes the second limiting protrusion 10 to slide upward into the second clamping groove 701 to limit the displacement of the first limiting protrusion 7, so that the limiting assembly is locked.

[0057] As a further scheme of the utility model, the wire row 6 is provided with a connecting hole at both ends; the connecting hole can be connected with a power supply device and an electrical equipment.

[0058] In this embodiment, the connecting hole is used for connecting the power supply device and the electrical equipment, and can also be connected with another busbar slot through the connecting hole, thereby prolonging the use length of the busbar slot.

[0059] As a further scheme of the utility model, the cover plate 2 is provided with a connecting panel, and the connecting panel can be provided with an electrical equipment.

[0060] In the embodiment, the electrical equipment is connected through the connecting panel, so that the electrical equipment is prevented from directly contacting the wire bar 6, thereby ensuring the safety of the electrical equipment and the bus duct.

[0061] The above embodiments are exemplary but not restrictive, and the technical scheme of the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model, and all of them are included in the utility model.
