Description

Technical Field

[0001] This utility model relates to the field of busbar trunking, and in particular to a fully enclosed resin-cast waterproof busbar trunking. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. It is used to distribute a large amount of power to various components of a distributed system and has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Existing technologies, such as the utility model patent with publication number CN219420236U, disclose a waterproof busbar trunking rod. A cover plate is fixedly connected to the side of the busbar trunking; the cover plate has holes in its center; multiple sets of holes are arranged in the center of the cover plate; small springs are fixedly connected inside the holes; small springs are fixedly connected inside each of the multiple sets of holes; sealing gaskets are fixedly connected to the ends of the multiple sets of small springs; and a connecting bolt is fixedly connected to the center of the cover plate. This step, during the installation of the busbar trunking, allows the small springs to compress, ensuring a tighter contact between the two sets of sealing gaskets. This reduces the possibility of moisture seeping into the busbar trunking after prolonged use, thereby reducing the risk of short circuits and ensuring electrical safety.

[0004] The inventors discovered in daily life that when two busbar trunkings are connected, the connection port of the device is exposed, allowing moisture to seep in from the external environment during use, thus affecting the use of the busbar trunking and resulting in poor waterproof sealing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing busbar trunking in terms of waterproofing and heat dissipation protection, and to propose a fully enclosed resin-cast waterproof busbar trunking.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fully enclosed resin-cast waterproof busbar trunking, comprising a base plate, an outer frame, a connection port, and a fixing frame. The outer frame is fixedly connected to the upper surface of the base plate, the connection port is fixedly connected to the inside of the outer frame, and the fixing frame is fixedly connected to the outer surface of the outer frame. A waterproof component is provided on the surface of the fixing frame, and an installation component is fixedly connected to the upper surface of the waterproof component. The installation component includes a damping expansion joint located on the upper surface of the waterproof component, and an installation plate is fixedly connected to the upper end of the damping expansion joint.

[0007] Furthermore, the waterproof component includes a one-way lead screw and a protective frame. The one-way lead screw is rotatably connected to the side surface of the fixed frame near the connection port. The outer surface of the one-way lead screw is threaded with the protective frame. The end of the one-way lead screw away from the fixed frame is fixedly connected to a rotating disk to achieve the waterproof effect.

[0008] Furthermore, the top and bottom ends of the outer frame are fixedly connected with sliding strips, which enhances the sealing between the outer frame and the protective frame.

[0009] Furthermore, heat dissipation vents are provided on both sides of the outer frame near the connection port to facilitate heat dissipation of the busbar during operation, prevent heat accumulation from causing a decline in the performance of the busbar, and extend its service life.

[0010] Furthermore, the protective frame is slidably connected to both ends of the outer surface of the outer frame, and two sliding strips are fixedly connected to the top and bottom surfaces of the outer frame, ensuring that the protective frame can effectively prevent moisture from entering the connection port when it is moved or fixed.

[0011] Furthermore, the inner walls on both sides of the protective frame near the slider are provided with grooves. The grooves fit into the slider, and the fitting structure not only ensures the smooth sliding of the protective frame, but also prevents water from seeping in from the gaps.

[0012] Furthermore, the mounting plates are located on the upper surfaces of the two protective frames, and the surfaces of the mounting plates are provided with mounting holes to facilitate the overall installation of the busbar trunking into the designated position. The design of the mounting holes makes the installation process more stable and convenient.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the waterproof component allows for easy operation by rotating the rotating disc, which in turn rotates the one-way lead screw, causing the protective frame to slide along the slide bar. This completely covers the connection port. The cooperation between the one-way lead screw and the protective frame effectively prevents moisture from entering the busbar trunking from the external environment. Even in humid, waterlogged, or potentially flooded conditions, the electrical components inside the busbar trunking are protected from water damage, significantly reducing the risk of short circuits caused by water ingress. This ensures the safe and stable operation of the power system and reduces power outages and related economic losses caused by electrical faults.

[0015] 2. In this utility model, the damping expansion joint in the installation assembly greatly facilitates the installation of busbar trunking. In actual installation, due to the diversity and complexity of the installation environment, it is often difficult to achieve a perfectly flat installation surface. The damping expansion joint can automatically adjust its height according to different installation requirements, compensating for differences in the flatness of the installation surface, allowing the mounting plate to better fit the installation surface. This simplifies the pre-installation preparation work, eliminates the need for tedious leveling of the installation surface, reduces installation errors caused by uneven installation surfaces, improves installation accuracy and efficiency, and also reduces vibrations during impacts, preventing damage to the device.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a fully enclosed resin-cast waterproof busbar trunking, including a base plate 1, an outer frame 2, a connection port 3 and a fixing frame 4. The outer frame 2 is fixedly connected to the upper surface of the base plate 1, the connection port 3 is fixedly connected to the inside of the outer frame 2, the fixing frame 4 is fixedly connected to the outer surface of the outer frame 2, a waterproof component 5 is provided on the surface of the fixing frame 4, and an installation component 6 is fixedly connected to the upper surface of the waterproof component 5.

[0024] The specific settings and functions of these functions will be explained in detail below.

[0025] In this embodiment: the mounting component 6 includes a damping expansion joint 61 located on the upper surface of the waterproof component 5, and the upper end of the damping expansion joint 61 is fixedly connected to the mounting plate 62.

[0026] The effect achieved by the above components is as follows: through the expansion and contraction characteristics of the damping expansion joint 61, the height of the mounting plate 62 can be finely adjusted during the installation process to adapt to different installation environments and requirements, ensuring the stability and flatness of the installation, and also facilitating connection with other equipment or structures, achieving the effect of shock absorption during use.

[0027] Specifically, the waterproof component 5 includes a one-way screw 51 and a protective frame 52. The one-way screw 51 is rotatably connected to the side surface of the fixed frame 4 near the connection port 3. The outer surface of the one-way screw 51 is threaded with the protective frame 52. The end of the one-way screw 51 away from the fixed frame 4 is fixedly connected to a rotating disk 53.

[0028] The effect achieved by the above components is as follows: when in use, by rotating the rotating disk 53, the one-way lead screw 51 rotates accordingly, thereby driving the protective frame 52 to slide along the slide bar 21, which can completely cover the connection port 3, effectively preventing moisture from entering the busbar trunking from the connection port 3 and improving the waterproof performance of the busbar trunking.

[0029] Specifically, the top and bottom of the outer frame 2 are fixedly connected with slide bars 21.

[0030] The effect achieved by the above components is as follows: the slider 21 provides guidance and support for the sliding of the protective frame 52, making the protective frame 52 more stable and smooth during movement, while also enhancing the sealing between the outer frame 2 and the protective frame 52, further preventing moisture from seeping in.

[0031] Specifically, heat dissipation vents 22 are provided on both sides of the outer frame 2 near the connection port 3.

[0032] The effect achieved by the above components is that during the operation of the busbar trunking, the heat dissipation vent 22 can dissipate the heat generated inside in a timely manner, avoiding heat accumulation that could lead to excessively high busbar trunking temperatures, thereby ensuring the normal operation of the busbar trunking, extending its service life, and also helping to maintain the stable performance of the busbar trunking and improve the safety and reliability of power transmission.

[0033] Specifically, the protective frame 52 is slidably connected to both ends of the outer surface of the outer frame 2, and two slide bars 21 are fixedly connected to the top and bottom surfaces of the outer frame 2 respectively.

[0034] The effect achieved by the above components is that the structural design allows the protective frame 52 to fit tightly against the surface of the outer frame 2, forming a complete waterproof barrier, which better prevents moisture from entering the connection port 3, and the two sliders 21 can share the weight of the protective frame 52 and the friction during sliding, making the movement of the protective frame 52 easier and more stable.

[0035] Specifically, the inner walls of the protective frame 52 near the slider 21 are provided with grooves 23, which fit into the slider 21.

[0036] The effect achieved by the above components is that the matching structure of the sliding groove 23 and the sliding strip 21 can not only ensure the accuracy and stability of the protective frame 52 during the sliding process and prevent it from shifting or shaking, but also further improve the sealing between the outer frame 2 and the protective frame 52, effectively prevent water from seeping in from the gaps, and enhance the waterproof effect of the busbar trunking.

[0037] Specifically, the mounting plate 62 is located on the upper surface of the two protective frames 52, and the surface of the mounting plate 62 is provided with mounting holes 7.

[0038] The aforementioned components achieve the following effects: the mounting plate 62 is used to fix the busbar trunking in the designated position; the design of the mounting holes 7 facilitates installation using bolts and other connecting parts, making the installation process more convenient and stable, and ensuring that the busbar trunking will not shift or shake during use.

[0039] Working principle: During installation, the busbar trunking is first fixed in a suitable position through the mounting holes 7 on the mounting plate 62. Then, the rotating disk 53 is rotated as needed, causing the one-way screw 51 to drive the protective frame 52 to slide along the slide bar 21 until the protective frame 52 completely covers the connection port 3, forming a waterproof protection. During the operation of the busbar trunking, the heat dissipation vent 22 continuously dissipates heat, ensuring a stable internal temperature of the busbar trunking. The damping expansion joint 61 can be finely adjusted in height to the mounting plate 62 according to the actual installation conditions to ensure the stability and flatness of the installation. It can also reduce damage caused by vibration when subjected to impact, increasing the service life of the device.
