Description

Technical Field

[0001] The utility model relates to the technical field of dense bus ducts, and more particularly to a dense bus duct that is convenient for wiring. Background Art

[0002] A dense bus duct is an electrical device used for centralized wiring in power systems. It is usually made of metal and has multiple conductors that are designed to be tightly arranged to transmit large amounts of electrical energy in a small space. The main advantage of dense bus duct is that it can efficiently manage and distribute electricity while saving space and reducing wiring work. Existing dense bus ducts usually consist of a shell, a cover, copper busbars, and insulating materials. The cover is usually installed on the shell by combining multiple screws and nuts. When the copper busbars need to be wired into the shell, workers need to use professional tools to tighten multiple screws to install the cover, which reduces the efficiency of copper busbar wiring installation and is not convenient for subsequent maintenance. Secondly, during the use of existing dense bus ducts, the copper busbars inside the shell will generate a certain amount of heat, making the temperature inside the shell higher. Long-term high-temperature operation will accelerate the aging of the bus duct insulation material, thereby shortening its service life. Utility Model Content

One end of the screw 28 passes through the limit plate 27 and is rotatably connected to a block 29 that cooperates with the gear ring 26. One side of the block 29 is slidably connected to the shell 1 through a track structure.

[0039] Specifically, when the handle 6 rotates, the handle 6 drives the gear ring 26 to rotate. When the handle 6 does not need to rotate, the screw 28 is rotated. Since the screw 28 is threadedly connected to the limit plate 27, the screw 28 rotates and moves toward the gear ring 26. The screw 28 drives the block 29 to move along the sliding connection with the shell 1. The block 29 clamps the gear ring 26, thereby fixing the handle 6.

[0040] In summary, when the overall equipment is in use:

[0041] When the copper busbar 18 needs to be wired, a plurality of jacks matching the copper busbar 18 are provided on the fireproof board 15. The copper busbars 18 are inserted into the shell from the jacks of the fireproof board 15 on one side and extended from the jacks of the fireproof board 15 on the other end. The copper busbar 18 extending into the shell 1 will be placed on the first limit block 16. The cover 2 is placed on the upper end of the shell 1 so that the plurality of fixing blocks 9 are respectively inserted into the fixing grooves 11. The handle 6 is turned, and the handle 6 drives the rotating rod 5 to rotate. The rotating rod 5 drives the two driving bevel gears 7 to rotate, and the driving bevel gear 7 drives the driven bevel gear 7 to rotate. The bevel gear 10 rotates, and the driven bevel gear 10 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 is provided with two threaded areas in opposite directions, so that the multiple fixing blocks 9 move to both sides along the fixing groove 11. When the fixing block 9 moves to one end of the moving groove 12, the fixing block 9 will be stuck in the fixing groove 11, thereby fixing the cover body 2. At the same time, the cover body 2 drives the multiple second limit blocks 17 to be installed on the multiple copper bars 18. The copper bars 18 are fixed with the cooperation of the first limit blocks 16 and the second limit blocks 17. The first limit blocks 16 and the second limit blocks 17 are both made of insulating materials. Two protective plates are provided on both sides of the housing 1.

[0042] When heat dissipation is required during the entire use of the bus duct, the heat generated in the shell 1 can be dissipated through the heat dissipation fins 13, and the motor 24 is started. The motor 24 drives the rotating column 23 to rotate, and the rotating column 23 drives multiple active bevel gears 25 to rotate. Each active bevel gear 25 drives the bevel gear 22 to rotate, and drives the bevel gear 22 to drive the rotating shaft 21 to rotate. Each rotating shaft 21 drives a group of fan blades 14 to rotate to blow air to the heat dissipation fins 13.

[0043] When the throttle 6 needs to be fixed, when the throttle 6 rotates, the throttle 6 drives the gear ring 26 to rotate. When the throttle 6 does not need to be rotated, the screw 28 is rotated. Since the screw 28 is threadedly connected to the limit plate 27, the screw 28 rotates and moves toward the gear ring 26. The screw 28 drives the clamping block 29 to move along the sliding connection with the shell 1. The clamping block 29 clamps the gear ring 26, thereby fixing the throttle 6.
