Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and particularly relates to a waterproof bus duct. Background Art

[0002] A bus duct is a closed metal device composed of copper or aluminum bus bars, used to distribute relatively large power to each component of a decentralized system. In indoor low-voltage power transmission trunk line engineering projects, it has increasingly replaced wire and cable. In developed countries abroad, for the outgoing lines of distribution rooms in buildings above twelve floors, that is, for the main lines leading to each floor, more than ninety percent use bus ducts. With the development of the times, the improvement of living standards, and the progress of industrial automation, the power consumption load is increasing. Using bus ducts to replace cables, especially in places such as hotels, factories, high-rise buildings, and public facilities, has become a development trend.

[0003] Most of the existing bus ducts basically have insufficiently strict waterproofing, which may lead to circuit short circuits or fires. Most of the problems occur in the outer protection box of the bus duct. The box structure is not tight enough. In humid areas or rainy areas, water or water vapor can enter the interior through the gaps in the box body, resulting in internal short circuit damage. In view of this, a waterproof bus duct is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to at least solve one of the technical problems existing in the prior art, and provide a waterproof bus duct, which can solve the problems that most bus ducts basically have insufficiently strict waterproofing, leading to circuit short circuits or fires. Most of the problems occur in the outer protection box of the bus duct. The box structure is not tight enough. In humid areas or rainy areas, water or water vapor can enter the interior through the gaps in the box body, resulting in internal short circuit damage.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A waterproof bus duct includes a first waterproof shell and a second waterproof shell, and the first waterproof shell and the second waterproof shell are arranged opposite to each other in an L shape.

[0006] Sealing end caps are respectively arranged inside both ends of the first waterproof shell and the second waterproof shell. The sealing end caps are in a square shape with a hole in the middle, and a bus bar of the bus duct is arranged inside the sealing end cap.

[0007] An insulating partition is fixedly welded between adjacent bus bars of the bus duct.

[0008] A sealing structure is arranged on the first waterproof shell and the second waterproof shell.

[0009] Preferably, a sealing rubber pad is fixedly connected inside the sealing end cap. The sealing rubber pad is also in a square shape with a hole in the middle, and the bus bar of the bus duct is arranged inside the sealing rubber pad.

[0010] Preferably, the sealing structure includes two groups of sealing blocks, with two sealing blocks in each group. The two groups of sealing blocks are respectively fixedly connected to one end of the first waterproof housing and the second waterproof housing.

[0011] An E-shaped sealing groove is formed at one end of the first waterproof housing and the second waterproof housing away from the sealing block.

[0012] Each group of sealing blocks is respectively fixedly clamped at two grooves of the sealing groove.

[0013] Fixing screws are respectively threadedly connected to the first waterproof housing and the second waterproof housing, and the fixing screws are threadedly connected to the sealing blocks.

[0014] Preferably, the sealing structure further includes a square frame-shaped sealing frame, and the sealing frame is fixedly connected to the outside of the sealing end cover.

[0015] Mounting holes are formed on the two horizontal plates and the two vertical plates of the sealing frame, and water swelling rubber water stop strips are fixedly connected inside the mounting holes.

[0016] L-shaped mounting grooves are formed inside both the first waterproof housing and the second waterproof housing, and the sealing frame is clamped inside the mounting grooves.

[0017] Preferably, heat dissipation fins are fixedly connected to the outside of both the first waterproof housing and the second waterproof housing.

[0018] Contact grooves are formed on the heat dissipation fins.

[0019] Preferably, external fixing holes are formed on the busbar copper bar.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] (1). For this waterproof busbar, the sealing block is inserted into the sealing groove, and then the two are fixed by the fixing screw. Since the sealing block is inserted into the sealing groove, the gap between the two is reduced, thereby ensuring the sealing performance of the first waterproof housing and the second waterproof housing. By clamping the sealing frame inside the mounting groove, the ends of the first waterproof housing and the second waterproof housing are made more airtight, reducing the generation of gaps. At the same time, under the action of the water swelling rubber water stop strip, once water vapor invades, the water swelling rubber water stop strip expands, causing the volume of the sealing frame to slightly increase, thereby re-sealing the connection part. Therefore, water vapor can be effectively blocked, preventing the water vapor from corroding the busbar copper bar and ensuring the stability of the busbar copper bar during use.

[0022] (2) The waterproof bus duct increases the contact area between the bus duct shell and the outside by setting the heat dissipation fins, thereby improving the heat dissipation efficiency. Under the action of the contact groove, the heat dissipation fins can have a larger contact area with the outside world, thereby allowing heat to be quickly replaced and discharged.

[0034] Please refer to Figure 1-5 , the present utility model provides a technical solution: a waterproof busbar, including a first waterproof shell 1 and a second waterproof shell 2, the first waterproof shell 1 and the second waterproof shell 2 are arranged in an L shape opposite to each other;

[0035] Sealing end caps 6 are respectively arranged inside both ends of the first waterproof shell 1 and the second waterproof shell 2, the sealing end caps 6 are in a square frame shape, and a busbar copper row 4 is arranged inside the sealing end caps 6;

[0036] An insulating partition 3 is fixedly welded between two adjacent busbar copper rows 4;

[0037] A sealing structure is arranged on the first waterproof shell 1 and the second waterproof shell 2;

[0038] After the busbar copper row 4 is welded to the insulating partition 3, it is fixed inside the first waterproof shell 1 and the second waterproof shell 2 by bolts;

[0039] External fixing holes 5 are provided on the busbar copper row 4;

[0040] Through the provided external fixing holes 5, when the busbar copper row 4 is docked with external equipment, fixing bolts can be used to fix the busbar copper row 4 through the external fixing holes 5, making it more stable after docking with external equipment and not prone to detachment.

[0041] Furthermore, a sealing rubber pad 9 is fixedly connected inside the sealing end cap 6, the sealing rubber pad 9 is also in a square frame shape, and the busbar copper row 4 is arranged inside the sealing rubber pad 9;

[0042] Through the provided sealing rubber pad 9, due to the soft performance of the rubber itself, the gap between the busbar copper row 4 and the sealing end cap 6 can be effectively reduced, thereby ensuring the sealing performance of the busbar and thus ensuring the waterproof effect.

[0043] Furthermore, the sealing structure includes two groups of sealing blocks 15, each group of sealing blocks 15 has two sealing blocks 15, and the two groups of sealing blocks 15 are fixedly connected to one end of the first waterproof shell 1 and the second waterproof shell 2 respectively;

[0044] An E-shaped sealing groove 14 is formed on one end of the first waterproof shell 1 and the second waterproof shell 2 away from the sealing block 15;

[0045] Each set of sealing blocks 15 is fixedly clamped at two grooves of the sealing groove 14;

[0046] The first waterproof housing 1 and the second waterproof housing 2 are respectively threadedly connected with fixing screws 16, and the fixing screws 16 are threadedly connected to the sealing block 15;

[0047] When the first waterproof case 1 and the second waterproof case 2 need to be combined, the sealing block 15 only needs to be inserted into the sealing groove 14. At this time, the two are fixed by fixing screws 16. Since the sealing block 15 is inserted into the sealing groove 14, the gap between the two is reduced, thereby ensuring the sealing performance of the first waterproof case 1 and the second waterproof case 2, thereby ensuring the waterproof effect;

[0048] Furthermore, the sealing structure further includes a U-shaped sealing frame 7, which is fixedly connected to the outer side of the sealing end cover 6;

[0049] The sealing frame 7 is made of rubber. The two horizontal plates and the two vertical plates of the sealing frame 7 are provided with mounting holes 10. The interior of the mounting holes 10 is fixedly connected with a water-swelling rubber waterstop strip 11.

[0050] The first waterproof housing 1 and the second waterproof housing 2 are both provided with an L-shaped mounting groove 8, and the sealing frame 7 is clamped in the mounting groove 8;

[0051] By clamping the sealing frame 7 into the interior of the mounting groove 8, the ends of the first waterproof shell 1 and the second waterproof shell 2 are made tighter, and the generation of gaps is reduced. At the same time, under the action of the water-swelling rubber waterstop strip 11, once water vapor invades, the water-swelling rubber waterstop strip 11 expands, causing the volume of the sealing frame 7 to slightly increase, thereby re-sealing the connection. Therefore, water vapor can be effectively blocked, preventing water vapor from corroding the busbar copper bar 4, while ensuring the stability of the busbar copper bar 4 during use;

[0052] Furthermore, the exteriors of the first waterproof shell 1 and the second waterproof shell 2 are both fixedly connected with heat dissipation fins 12;

[0053] The heat dissipation fin 12 is provided with a contact groove 13;

[0054] The heat dissipation fins 12 are provided to increase the contact area between the bus duct shell and the outside, thereby improving the heat dissipation efficiency. Under the action of the contact grooves 13, the heat dissipation fins 12 can have a larger contact area with the outside world, thereby allowing heat to be quickly replaced and discharged.

[0055] Working Principle: When assembling the first waterproof case 1 and the second waterproof case 2, simply insert the sealing block 15 into the sealing groove 14. The two are then fixed together using the fixing screws 16. Since the sealing block 15 is inserted into the sealing groove 14, the gap between the two is reduced, thereby ensuring the sealing performance of the first waterproof case 1 and the second waterproof case 2, thereby ensuring the waterproof effect.

[0056] By clamping the sealing frame 7 inside the mounting groove 8, the ends of the first waterproof shell 1 and the second waterproof shell 2 are made tighter, reducing the generation of gaps. At the same time, under the action of the water-swelling rubber waterstop strip 11, once water vapor invades, the water-swelling rubber waterstop strip 11 expands, causing the volume of the sealing frame 7 to slightly increase, thereby re-sealing the connection. Therefore, it can effectively block water vapor, avoid water vapor from corroding the busbar copper busbar 4, and ensure the stability of the busbar copper busbar 4 during use.

[0057] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
