Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a bus duct with a dust cleaning function. Background Art

[0002] Closed bus duct (referred to as bus duct) is a bus system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive bars, insulating materials and related accessories. It can be made into plug-in closed busbars with plug-in junction boxes at intervals, or it can be made into feeder closed busbars without junction boxes in the middle.

[0003] The existing referenceable Chinese utility model patent with announcement number CN208767750U discloses a bus duct, including two cover plates, a first side plate and a second side plate, and an isolation block assembly; the isolation block assembly includes a plurality of pairs of isolation blocks arranged side by side; each pair of isolation blocks can be detachably installed between the two cover plates; the bus duct also includes a clamping mechanism that can be telescopically installed on the second side plate; the clamping mechanism includes a telescopic rod, a pressure plate, and an elastic member; one end of the isolation block assembly abuts against the first side plate, and the other end of the isolation block assembly abuts against the pressure plate. The beneficial effect of implementing the utility model is that the bus duct adopts the structure of a clamping mechanism that can be telescopically installed on the second side plate. When adding or reducing isolation blocks, the clamping mechanism can also press the isolation block assembly between the two cover plates. Users can add or reduce corresponding isolation blocks and copper bars according to actual needs. It is easy to assemble and disassemble, making the application range of the bus duct wider.

[0004] The bus duct is generally fixed by hoisting. After long-term use, dust is easily accumulated on the top of the bus duct, which is very inconvenient to clean and affects the heat dissipation of the bus duct. At the same time, the conductive bars inside the bus duct will generate a certain amount of heat after power is turned on. However, most of the existing bus ducts are closed structures and the internal heat cannot be quickly conducted to the outside. Utility Model Content

[0009] As the preferred technical solution of the utility model, the top plate is mirror-symmetrical in the upper and lower parts, and the side plates are mirror-symmetrical in the left and right parts to form a rectangular pipe structure. The flat heat pipe is installed equidistantly on the left side of the side plate, and the flat heat pipe runs through the side plate. The top plate and the side plate can protect the internal conductive bar and play an insulating role.

[0010] As an optimal technical solution of the utility model, the limit plate is installed equidistantly between the top plates front and back, the heat shrink sleeve is installed equidistantly left and right inside the limit plate, and the heat shrink sleeve is fixedly connected to the top plate through the limit plate; the limit plate can limit the position of the conductive bar.

[0011] As the preferred technical solution of the utility model, the end cover is installed at the front and rear ends of the side plate in a mirror-symmetrical manner, the front and rear ends of the conductive bar pass through the end cover, and the insulating bolt horizontally passes through the end cover, the conductive bar, and the insulating sleeve; the end cover can close the front and rear ends of the top plate and the side plate.

[0012] As a preferred technical solution of the utility model, a snap-on structure engaged with the side panel is provided at the lower end of the baffle, the cross section of the baffle is triangular, and a sliding connection is formed between the slider and the baffle; the baffle can block dust.

[0014] As the preferred technical solution of the utility model, the pulley and the base are rotatably connected, the steel cable passes around the pulleys at the front and rear ends of the side panel, and the front and rear ends of the steel cable are respectively fixedly connected to the front and rear facades of the lower end of the slider; the steel cable can drive the slider to move.

[0015] Compared with the prior art, the utility model provides a bus duct with dust cleaning function, which has the following beneficial effects:

[0016] 1. The utility model sets a baffle, and a snap-on structure engaged with the side panel is set at the lower end of the baffle. The cross-section of the baffle is triangular.

The steel cable passes around the pulleys at the front and rear ends of the side panel, and the front and rear ends of the steel cable are respectively fixedly connected to the front and rear facades of the lower end of the slider. During use, dust will stay above the baffle. When cleaning is needed, the steel cable is pulled by a tool to connect the hook to drive the slider to move. Since the slider is engaged with the baffle, the dust above the baffle will be cleaned during the slider's forward and backward movement. This method can prevent dust from being deposited above the top plate and prevent dust from affecting the heat dissipation of the bus duct.

The flat heat pipe penetrates the side panel and extends to the inner cavity of the pipe structure formed by the top panel and the side panel. When the conductive bar is energized to generate heat, one end of the flat heat pipe is heated, and the liquid in the capillary tube inside the flat heat pipe evaporates rapidly. The steam flows to the other end of the flat heat pipe under a small pressure difference, releases heat, and condenses into liquid again. The liquid then flows back to the evaporation section along the porous material by the action of capillary force, and the cycle continues, thereby ensuring the sealing of the bus duct while improving the heat dissipation effect.
