Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a dense aluminum alloy shell waterproof busbar. Background Technology

[0002] Busbar trunking is an integrated power transmission solution used in power systems, widely applied in various buildings, industrial plants, data centers, power plants, and other locations. It transmits power through a series of conductive busbars and an insulating casing. Existing busbar trunking systems only address waterproofing with covers or gaskets. Their protection level is limited to IP66 as defined in GB / T4208-2017. While they can withstand slight water droplets, they cannot effectively seal against larger volumes of water. This means that the busbar trunking's sealing performance cannot withstand harsher environments, such as prolonged immersion or high water pressure. In extreme weather conditions or high humidity environments, water may seep into the busbar trunking through gaps in the gaskets or covers, affecting the normal operation of the power system. Utility Model Content

[0003] The purpose of this invention is to provide a dense aluminum alloy shell waterproof busbar trunking to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dense aluminum alloy shell waterproof busbar trunking, comprising:

[0005] Busbar trunking body;

[0006] A connecting block is placed at the end of the busbar trunking body. The connecting block and the busbar trunking body form a convex structure. A semi-circular hole is provided on both sides of the connecting block.

[0007] A connector is placed at the end of the busbar trunking body. The connector includes a connector base plate, and two connector side plates are installed on the top of the connector base plate. The connector side plates have a second semicircular hole that mates with the first semicircular hole. When the two ends of the connector are engaged with the busbar trunking body, an injection cavity is formed inside the connector. The second semicircular hole and the first semicircular hole together form a limiting sealing hole, which is used to form a sealing rod for sealing and limiting. An injection gap is provided between the limiting sealing hole and the injection cavity.

[0008] Preferably, sealing blocks that mate with the side plates of the connector are embedded on both sides of the connector block.

[0009] Preferably, a sealing strip with a right-angled triangular structure is fixed to one side of the bottom of the connector side plate.

[0010] Preferably, a connector torque screw is installed in the middle of the connector side plate.

[0011] Preferably, a connector cover plate is installed on the top of the connector side plate, and a grounding bar is installed on the top of the connector cover plate by fastening bolts, and the grounding bar is fixedly connected to the fastening bolts.

[0012] Preferably, the interior of the injection cavity is provided with a waterproof filling layer, which is made of epoxy resin or volcanic rock minerals.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the connecting block and the connector cooperate to form a limiting sealing hole. After the glue is injected, the filler solidifies in the limiting sealing hole to form a cylindrical device, which effectively prevents the connecting block from separating from the side plate of the connector and enhances the stability of the connection; the filler enters the limiting sealing hole along the glue injection seam and fills the glue injection seam, which increases the overall sealing performance and effectively prevents external dust, moisture and other substances from entering the busbar trunking; a sealing block is set on the outside of the connecting block, and the sealing block is connected with the side plate of the connector by bolts to contact and squeeze to seal, which further improves the sealing performance of the connection part; a sealing strip is set at the bottom of the side plate of the connector to seal between the side plate of the connector and the bottom plate of the connector, preventing the leakage of liquid sealant and ensuring the smooth progress of the glue injection process and the sealing effect after glue injection.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this utility model provides a technical solution: a dense aluminum alloy shell waterproof busbar trunking, comprising: a busbar trunking body 1; a connecting block 2 fixedly connected to the end of the busbar trunking body 1, the connecting block 2 and the busbar trunking body 1 forming a convex structure, a copper busbar passing through one end of the connecting block 2, and semi-circular holes 4 on both sides of the connecting block 2; a connecting head 5 installed at the end of the busbar trunking body 1 by bolts, the connecting head 5 including a connecting head base plate 6, two connecting head side plates 7 installed on the top of the connecting head base plate 6, and a semi-circular hole 13 inside the connecting head side plate 7 that mates with the semi-circular hole 4; when the two ends of the connecting block 2 mate with the busbar trunking body 1, an injection cavity is formed inside the connecting block 2, and the semi-circular hole 13 and the semi-circular hole 4 form a limiting sealing hole 15, which is used to form a sealing rod for sealing and limiting; an injection gap 14 is provided between the limiting sealing hole 15 and the injection cavity.

[0023] It should be noted that in this embodiment, the end of the connecting block 2 is inserted between the two connecting head side plates 7, and the copper busbar at the end of the connecting block 2 is also inserted between the two connecting head side plates 7. Under the action of the insulating plate between the two connecting head side plates 7, corresponding separation and clamping are achieved. After clamping and connection, the connecting head base plate 6 is installed at the bottom of the connecting head side plate 7 with bolts. At this time, the connecting head base plate 6, the two connecting head side plates 7 on both sides, and the connecting blocks 2 at both ends form a glue injection cavity with an opening at the top. At this time, the semi-circular hole 13 and the semi-circular hole 4 form a limiting sealing hole 15. At this time, waterproof sealing filler is injected into the glue injection cavity. During the process of filling the glue injection cavity with liquid filler, the filler enters the limiting sealing hole 15 along the glue injection seam 14 between the connecting head side plate 7 and the connecting block 2. After the filler cures, it forms a cylindrical device in the limiting sealing hole 15, which can prevent the connecting block 2 from separating from the connecting head side plate 7. Furthermore, by filling the glue injection seam 14, its sealing performance can be increased.

[0024] In one embodiment, sealing blocks 3 that mate with the connector side plate 7 are embedded on both sides of the connecting block 2.

[0025] It should be noted that in this embodiment, a threaded hole is provided on the outer side of the connecting block 2 corresponding to the position of the sealing block 3, and a through hole is provided on the connecting head side plate 7 corresponding to the position of the threaded hole. The connecting head side plate 7 is connected to the connecting block 2 by passing a bolt through the through hole and connecting the threaded hole, so that the sealing block 3 contacts the connecting head side plate 7 and the contact surface is squeezed and sealed.

[0026] In one embodiment, a right-angled triangular sealing strip 8 is fixedly connected to one side of the bottom of the connector side plate 7, a connector torque screw 10 is installed in the middle of the connector side plate 7, a connector cover plate 9 is installed on the top of the connector side plate 7, and a grounding strip 11 is installed on the top of the connector cover plate 9 by fastening bolts 12, and the grounding strip 11 is fixedly connected to the fastening bolts 12.

[0027] It should be noted that in this embodiment, multiple insulating sheets are provided on the outside of the connector torque screw 10 and between the two connector side plates 7. The copper busbar is placed between the insulating sheets, and the connector side plate 7 is pressed towards the center by rotating the connector torque screw 10. In this way, the copper busbar is clamped and fixed under the action of the connector side plate 7 and the insulating sheets. The connector side plate 7 clamps the connecting block 2 and the sealing block 3 between the two connector side plates 7. Since a sealing strip 8 is installed at the bottom of the connector side plate 7, the connector side plate 7 and the connector base plate 6 can be sealed under the action of the sealing strip 8 to prevent the leakage of liquid sealant. After the sealant has cured and formed, the connector side plate 7 is installed on the top of the connector side plate 7 by bolts, and the grounding strip 11 is installed on the top of the connector base plate 6 by bolts.

[0028] In one embodiment, the interior of the injection cavity is provided with a waterproof filler layer 16, which is made of epoxy resin or volcanic rock minerals.

[0029] It should be noted that in this embodiment, epoxy resin or volcanic rock minerals are used as fillers and injected into the injection cavity. After curing, the filler can fill the entire injection cavity, ensuring that dust or fine particles are completely prevented from entering and protecting the internal components from external contamination. Under the coating of the colloid, it can withstand deep water immersion, so that its protection level can reach IP68.
