Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a multifunctional bus duct cover plate. Background Art

[0002] Bus duct is a device used for power transmission and distribution in power systems. It is a long and narrow channel, usually made of metal materials, used to install and protect power busbars. The conductor bars of bus duct are usually made of metal, such as aluminum alloy, galvanized steel or copper. Its shape can be rectangular, circular or flat, depending on the application requirements. The conductor bars of bus duct are usually surrounded by a shell and made of insulating material. Bus duct is usually installed on the wall, ceiling or ground. In the actual installation process, bus duct is usually segmented to adapt to different power distribution requirements. Bus duct is widely used in power distribution systems in buildings, industrial plants, commercial centers, hospitals, airports and other places.

[0003] The bus duct cover is a covering installed above the bus duct to protect the conductor bars in the bus duct and prevent external objects or personnel from accidentally contacting the conductor bars, thereby providing electrical safety and mechanical protection. Usually, the bus duct cover can be divided into two types: open and sealed. The open cover usually has ventilation holes or slots for heat dissipation and cooling, and is suitable for some places with low current loads or where strict dust and water resistance requirements are not required. The sealed cover has a completely enclosed structure that can provide higher dust, water and corrosion resistance, and is suitable for places that require a higher electrical safety level. Both methods are usually connected to the bus duct body through screws, clips or other fixing devices. In some special scenarios, the installation of bus duct covers at different times requires both open and sealed types. At this time, the existing bus duct covers cannot meet both requirements at the same time and can only be solved by dismantling and reinstalling, which is time-consuming, labor-intensive, and costly.

[0027] Specifically, the cover plate assembly includes a heat dissipation plate 2 and a sealing plate 3, and the sealing plate 3 is inserted inside the heat dissipation plate 2;

[0028] Specifically, the heat dissipation plate 2 includes a top plate 21, on which a plurality of heat dissipation holes 211 are provided, and a functional plate 22 extends downward from the edges of the top plate 21. A mounting hole 23 is provided on one side of the functional plate 22, and a receiving cavity 24 is provided on the opposite functional plate 22, and a slide groove group 25 for the sealing plate 3 to move is provided on the other two side functional plates 22;

[0029] Specifically, the sealing plate 3 includes a movable plate 31, which is installed below the top plate 21 from the insertion port 23, and slider groups 32 cooperating with the slide groove groups 25 are provided on both sides of the movable plate 31. Sealing blocks 33 are also provided on the upper and lower sides of the movable plate 31, and the sealing blocks 33 on both sides act on the insertion port 23.

[0030] In this embodiment, a cover plate is installed at the top of the bus duct body 1. The main functions of the cover plate include protecting the conductor bars, providing electrical safety, mechanical protection, and dust and water resistance. Cover plates with different functions are installed according to different usage scenarios, and usually they cannot have both. In this embodiment, by combining the heat dissipation plate 2 and the sealing plate 3 together, the user can replace the function on the same cover plate without disassembling the bus duct body 1, thereby reducing the replacement cost.

[0031] Reference Figure 6-7 The slide groove group 25 includes grooves 251 arranged on the functional plates 22 on both sides. The inner walls on both sides of the groove 251 are also provided with positioning grooves 252, and the positioning grooves 252 are matched with the slider group 32.

[0034] In this embodiment, the sealing plate 3 cooperates with the slider group 32 and the slide groove group 25 to enable the movable plate 31 to move in the insertion port 23 and insert the other end thereof into the accommodating cavity 24. Since elastic sealing strips 241 are provided on the upper and lower sides of the accommodating cavity 24, when the movable plate 31 is inserted into the accommodating cavity 24, the elastic sealing strips 241 on the upper and lower sides will squeeze the two sides of the movable plate 31 to make it sealed as a whole. Similarly, sealing blocks 33 are also provided on the upper and lower sides of the other end of the movable plate 31, which are mainly used to seal the insertion port 23 and fix the movable plate 31 at the same time to improve the sealing performance of the cover plate.

[0037] In this embodiment, when the movable plate 31 is not needed, it can be pulled out from the insertion port 23 using the retracting groove 34 provided at one end. Since the functional plates 22 on both sides are provided with extended portions at the insertion port 23, the movable plate 31 can be freely placed on the side of the bus duct body 1 when being pulled out of the cover plate, without occupying the installation space and without affecting the overall installation stability. In addition, the heat dissipation holes 211 provided on the top plate 21 can realize the heat dissipation function of the bus duct cover plate.
