Description
Technical Field
[0001] This invention relates to the field of busbar trunking devices, specifically a sealed busbar trunking with waterproof function. Background Technology
[0002] Busbar trunking is a type of enclosed electrical transmission and distribution equipment consisting of a metal sheet (such as steel or aluminum sheet) as a protective shell, conductive busbars (copper or aluminum busbars), insulating materials, and accessories. It is mainly used for the transmission and distribution of high current and low voltage in power systems.
[0003] Most current busbar trunking systems use metal casings and are assembled by bolts, tapping, etc. Therefore, most existing busbar trunking systems have weak waterproof capabilities. Especially when the busbar trunking system is installed in an outdoor environment, it is often affected by rainwater during use, which causes water to enter the busbar trunking system and become damp. After long-term use, this leads to corrosion of the external casing structure, further affecting the transmission and use of the busbar trunking system. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a sealed busbar trunking with waterproof functionality, which solves the problem of poor waterproof performance of existing busbar trunking mentioned in the background section.

Both sides of the locking rod have threaded holes inside, and the locking rods on both sides are threaded to the outer walls of the threaded rods at both ends through the inner walls of the threaded holes.
[0009] Optionally, the heat dissipation component includes a heat dissipation plate, and a plurality of heat dissipation fins are fixedly connected to the bottom surface of the heat dissipation plate. The plurality of heat dissipation fins are distributed at intervals along the long side of the heat dissipation plate.
[0010] Optionally, the support assembly includes a connecting plate, with support plates rotatably connected to the bottom surface of the connecting plate near both ends, and the outer walls of the support plates on both sides slidably connected to the inner walls of the support frame. The connecting plate has sliders fixedly connected to both sides of its side walls, and rotating caps fixedly connected to the bottom surface of the connecting plate near both ends. A rotating shaft is fixedly connected to one end of the support plate, and a sliding hole is provided at the other end of the support plate. The inner side wall of the sliding hole is slidably connected to the outer side wall of the limiting rod. The support frame has limit grooves inside both side walls, a sliding groove inside the top surface of the support frame, several limit holes inside the bottom surface of the support frame on one side of the sliding groove, and a moving groove inside the bottom surface of the support frame on the other side of the sliding groove. Several of the limiting holes are evenly spaced and symmetrically distributed inside the bottom surface of the support frame.
[0011] Optionally, the outer sidewalls of the sliders on both sides of the connecting plate are slidably connected to the inner sidewalls of the limiting grooves on both sides. The support plates on both sides are rotatably connected to the inner walls of the rotating caps on both sides via the outer walls of the rotating shafts at the ends. The outer wall of the limiting rod is slidably connected to the inner wall of the moving groove, and the outer wall of the end of the limiting rod is movably inserted into the inner side of the limiting hole.
[0012] Optionally, the upper cover is movably connected to the sealing slots on both sides of the lower cover via sealing blocks on both side walls, and the outer side walls of the locking rods of the fastening components on both sides of the upper cover are movably connected to the inner side walls of the locking holes inside the locking blocks.
[0013] Optionally, the heat dissipation assembly is fixedly connected to the bottom surface of the heat dissipation plate and the bottom surface of the heat-conducting block at the bottom of the lower cover through the top surface of the heat dissipation plate, and the two side walls of the heat dissipation plate are fixedly connected to the inner side walls of the two short sections of the connecting plate, respectively.
[0014] This invention provides a sealed busbar trunking with waterproof function, which has the following beneficial effects: This waterproof, sealed busbar trunking system consists of an upper cover and a lower cover, which are connected by a sealing block and a sealing slot. The upper and lower covers are installed vertically. Each sealing block and slot is equipped with a sealing rubber gasket (first and second). These gaskets seal the joint between the sealing block and slot by compressing the rubber gaskets. The S-shaped joint further prevents rainwater intrusion, ensuring excellent waterproof performance through the sealed installation of the upper and lower covers.
[0015] This waterproof, sealed busbar trunking features a guide plate on the top surface of its upper cover. When rainwater or other liquids fall onto the guide plate, the inclined drainage surface on the bottom of the guide plate directs the water to flow out through the drain outlets on both sides of the guide plate. As the water flows out of the drain outlets, it passes through the drainage hopper, preventing water from dripping onto the sides of the device. By using the guide plate, the upper cover achieves excellent drainage and flow control.
[0016] This waterproof, sealed busbar trunking has a heat dissipation component fixedly connected to the bottom surface of the lower cover. When the upper cover and the busbar trunking body inside the lower cover are in use, the heat generated is transferred to the heat dissipation plate at the bottom through the heat-conducting block at the bottom of the lower cover. The heat is then dissipated through the heat dissipation plate and the heat dissipation fins on the bottom surface. The heat dissipation fins further increase the contact area with the air, thereby further improving the heat dissipation effect.
[0017] This waterproof, sealed busbar trunking system features support components on the bottom surfaces of both ends. Support plates are rotatably connected to the bottom of a connecting plate via a rotating shaft and a rotating cap. The bottom end of the support plate slides within a groove on the bottom surface of the support frame, while a limiting rod at the bottom of the support plate moves synchronously within a movable groove on the bottom surface of the support frame. By sliding the limiting rod into different limiting holes, the connecting frame, support plate, and support frame are fixed in place. The support frame then supports the entire device. Inserting the limiting rod into different limiting holes adjusts the distance between the connecting plate and the support frame, thus adjusting the support frame's height. During installation and use, the support components can be adjusted vertically to achieve height adjustment.
[0018] This waterproof, sealed busbar trunking has an upper cover and a lower cover that are fixed together by fastening components. By rotating the rotating rod, the threaded rods at both ends are rotated synchronously, which in turn drives the locking rods on both sides to slide from the slide cylinder into the locking holes, thereby securing the upper cover and the lower cover together and making it easier to install and remove the upper cover and the lower cover.

[0033] The method of using this invention: The waterproof sealed busbar trunking operates as follows: like Figures 1 to 11 As shown, firstly, the upper cover 1 and the lower cover 2 are placed on the upper and lower sides of the busbar trunking body 3 respectively, and then the upper cover 1 and the lower cover 2 are installed together. During this process, the upper cover 1 and the lower cover 2 are connected to each other by the sealing plug 12 and the sealing slot 22.

The top of the support plate 62 is rotatably set through the rotating shaft 621 and the rotating cap 612. On the bottom surface of the connecting plate 61, the support plate 62 rotates and adjusts between the connecting plate 61 and the support frame 63, thereby adjusting the distance between the connecting plate 61 and the support frame 63. By sliding the limiting rod 623 into different limiting holes 633, the connecting plate 61, the support plate 62 and the support frame 63 are fixed and limited. The support frame 63 supports the entire device. By inserting the limiting rod 623 into different limiting holes 633, the distance between the connecting plate 61 and the support frame 63 is adjusted, thereby achieving the effect of adjusting the support height of the support frame 63.
