Description

Technical Field

[0001] This utility model relates to the technical field of busbar equipment, specifically an improved busbar with waterproof function. Background Technology

[0002] Busbar trunking is a type of power transmission equipment used for centralized distribution of large currents. It consists of multiple sets of conductive bars encased in a metal shell and features modularity, high protection level, and flexible expansion. Its core function is to provide efficient and safe power trunk lines for industrial, commercial buildings, or data centers, replacing traditional cables, supporting large-capacity power transmission, and suitable for scenarios requiring high reliability, dense power distribution, or frequent adjustments to power load.

[0003] For example, the waterproof busbar trunking disclosed in Chinese patent literature (publication number: CN219760585U) allows the busbar trunking body to form a sealed space after installation and connection by setting waterproof components. This prevents water from affecting the upper and lower ends of the busbar trunking body. Furthermore, fixing the plug strip around the sealing plug can make the whole structure more stable.

[0004] However, this method relies solely on sealing blocks, sealing plates, and sealing strips to achieve waterproofing. Its sealing structure is simple and is a plug-in design, which can only provide basic protection for the inside of the connection end and lacks the coordinated protection of multiple sealing defenses. Utility Model Content

Similarly, multiple sets of fan-shaped heat sink structures are symmetrically arranged on the outer side of the second docking protective tube.

[0008] As a further embodiment of this utility model: the telescopic protective mechanism includes a connecting pipe ring, a sealing groove ring, and a telescopic sleeve. The connecting pipe ring is threaded to the inner side of the connecting disc. The sealing groove ring is fixedly connected to one end of the outer side of the connecting pipe ring. The sealing groove ring is adapted to the raised sealing ring. The telescopic sleeve is fixedly connected to one end of the connecting pipe ring and is fixedly connected to the docking protective tube.

[0009] As a further embodiment of this utility model: the telescopic protective mechanism II includes a connecting pipe ring II, a sealing groove ring II, and a telescopic sleeve II. The connecting pipe ring II is threadedly connected to the inner side of the connecting disc II. The sealing groove ring II is fixedly connected to one end of the outer side of the connecting pipe ring II. The sealing groove ring II is adapted to the raised sealing ring II. The telescopic sleeve II is fixedly connected to one end of the connecting pipe ring II. The telescopic sleeve II is fixedly connected to the connecting protective pipe II.

[0010] As a further embodiment of this utility model: the sealing mechanism includes a silicone rubber sealing ring, an inner sealing ring groove, and an outer limiting ring groove. The inner sealing ring groove is formed on both sides inside the silicone rubber sealing ring. The two sets of silicone rubber sealing rings are adapted to the back convex rings of the first and second docking protective tubes. The outer limiting ring groove is formed on both sides outside the silicone rubber sealing ring. Both sets of outer limiting ring grooves are adapted to the limiting ring.

[0011] As a further improvement of this utility model: the first docking protective tube and the second docking protective tube are snapped together, and the outer end of the second docking protective tube is also provided with a limiting ring structure.

[0012] As a further embodiment of this utility model: a connecting plate is also provided at the other end of the outer side of the busbar trunking body one, and a connecting plate is also provided at the other end of the outer side of the busbar trunking body two.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, firstly, the connecting pipe ring 1 of the telescopic protective mechanism 1 is rotated to thread it onto the connecting disc 1 of the busbar trunking body 1. Simultaneously, the sealing groove ring 1 engages with the raised sealing ring 1, forming two sealing lines at the interface to effectively block water. The busbar trunking body 2 is operated in the same manner, and its interface also forms two sealing lines to prevent water infiltration. Then, based on the distance between the ends of the busbar trunking body 1 and the busbar trunking body 2, the telescopic sleeve 1 and the telescopic sleeve 2 are pulled to make the connecting protective pipe 1 and the connecting protective pipe 2 fit together and form protection at the ends. Subsequently, the silicone rubber sealing ring is placed between the two connecting protective pipes, and the inner sealing ring groove engages with the raised ring on the back of the two pipes to form a radial seal. Finally, the limiting rings on the outer sides of the two connecting protective pipes are rotated. This allows the material to be embedded into the outer limiting ring groove. By squeezing, the silicone rubber sealing ring is tightly fitted, further enhancing the sealing effect. This creates two lines of sealing between the two connecting protective pipes, providing double protection against water damage at the connection point. The other ends of the busbar trunking body one and busbar trunking body two are also protected in the same way. This allows the expansion sleeve to flexibly adapt to the installation spacing, reducing the requirements for space and dimensional accuracy, making it suitable for complex sites. The components are assembled by threads or snap-fit ​​connections, facilitating quick assembly, disassembly, and maintenance, and improving construction efficiency. The multiple sets of fan-shaped heat dissipation fins on the outside of the connecting protective pipe extend into the pipe, ensuring heat dissipation while maintaining a seal, preventing heat accumulation, achieving a balance between sealing and waterproofing, and ensuring the long-term stable operation of the busbar trunking.

The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 6 In this embodiment of the utility model, an improved busbar trunking with waterproof function includes: a busbar trunking body 1 and a busbar trunking body 2, both of which serve as the main conductive structure to carry current transmission. A connecting plate 3 is fixedly connected to one end of the outer side of the busbar trunking body 1, which serves as a connection.

[0025] A raised sealing ring 4 is fixedly connected to the front of the connecting plate 3 as a sealing element. A connecting plate 5 is fixedly connected to one end of the outer side of the busbar body 2, which serves as a connection.

[0026] The inner side of the front of the connecting plate 13 is provided with a telescopic protective mechanism 17, the inner side of the front of the connecting plate 25 is provided with a telescopic protective mechanism 28, the front of the telescopic protective mechanism 17 is provided with a docking protective tube 19, one end of the outer side of the docking protective tube 19 is threadedly connected with a limit ring 10, the front of the telescopic protective mechanism 28 is provided with a docking protective tube 21, a sealing mechanism 12 is provided between the docking protective tube 19 and the docking protective tube 21, the docking protective tube 19 and the docking protective tube 21 are snapped together, one end of the outer side of the docking protective tube 21 is also provided with a limit ring 10 structure, the other end of the outer side of the bus trunking body 11 is also provided with a connecting plate 13, the other end of the outer side of the bus trunking body 22 is also provided with a connecting plate 25.

[0027] Reference Figure 1 , Figure 2 and Figure 4 Multiple sets of fan-shaped heat sinks 13 are symmetrically fixed to the outside of the first docking protective pipe 9. Part of the fan-shaped heat sinks 13 extend into the inside of the first docking protective pipe 9. The outside of the second docking protective pipe 11 is also symmetrically equipped with multiple sets of fan-shaped heat sinks 13. Through the multiple sets of fan-shaped heat sinks 13, the heat generated by the bus trunking during operation can be quickly transferred to the external environment, realizing the heat dissipation function, avoiding the problem of heat accumulation caused by sealing, achieving a balance between sealing and waterproofing and heat dissipation, and ensuring the long-term stable operation of the bus trunking.

[0028] Reference Figures 1 to 3 The telescopic protection mechanism 7 includes a connecting pipe ring 71, a sealing groove ring 72, and a telescopic sleeve 73. The connecting pipe ring 71 is threaded to the inside of the connecting disc 3. The sealing groove ring 72 is fixedly connected to one end of the connecting pipe ring 71 and is adapted to the raised sealing ring 4. The telescopic sleeve 73 is fixedly connected to one end of the connecting pipe ring 71 and is fixedly connected to the docking protection pipe 9. First, rotate the connecting pipe ring 71 in the telescopic protection mechanism 7 so that it is threadedly connected to the connecting disc 3 on the busbar trunking body 1, and make the sealing groove ring 72 and the raised sealing ring 4 cooperate. In this way, two sealing lines are formed at the interface, effectively preventing moisture from seeping in from this part.

[0029] Reference Figure 1 , Figure 4 and Figure 5The telescopic protective mechanism 28 includes a connecting pipe ring 281, a sealing groove ring 282, and a telescopic sleeve 283. The connecting pipe ring 281 is threaded to the inside of the connecting disc 25. The sealing groove ring 282 is fixedly connected to one end of the connecting pipe ring 281 and is adapted to the raised sealing ring 26. The telescopic sleeve 283 is fixedly connected to one end of the connecting pipe ring 281 and is fixedly connected to the docking protective pipe 211. First, rotate the connecting pipe ring 281 in the telescopic protective mechanism 28 so that it is threadedly connected to the connecting disc 25 on the busbar trunking body 22. Similarly, the sealing groove ring 282 and the raised sealing ring 26 are matched. Thus, two sealing lines are formed at this interface, effectively preventing moisture from seeping in from this part.

[0030] Reference Figure 1 and Figure 6 The sealing mechanism 12 includes a silicone rubber sealing ring 121, an inner sealing ring groove 122, and an outer limiting ring groove 123. The inner sealing ring groove 122 is located on both sides inside the silicone rubber sealing ring 121. The two sets of silicone rubber sealing rings 121 are adapted to the back convex rings of the first docking protection tube 9 and the second docking protection tube 11. The outer limiting ring grooves 123 are located on both sides outside the silicone rubber sealing ring 121. Both sets of outer limiting ring grooves 123 are adapted to the limiting ring 10. Pulling the first telescopic sleeve 73 and the second telescopic sleeve 83 causes the first docking protection tube 9 and the second docking protection tube 11 to come into contact and lock together. This forms a protective measure between the end of the busbar trunking body 1 and the end of the busbar trunking body 2. Then, the silicone rubber sealing ring 121 is fitted between the first docking protective tube 9 and the second docking protective tube 11, so that the inner sealing ring groove 122 is adapted and engaged with the convex ring on the back of the first docking protective tube 9 and the second docking protective tube 11 to form a radial seal. At the same time, the limiting ring 10 on the outside of the first docking protective tube 9 and the second docking protective tube 11 is rotated so that the limiting ring 10 is embedded in the outer limiting ring groove 123. In this way, the silicone rubber sealing ring 121 is tightly fitted between the two docking protective tubes by the compression and fixation of the limiting ring 10, which further enhances the sealing effect and prevents water from seeping in from the docking point. In this way, two sealing defenses are formed between the two docking protective tubes, providing double protection for the waterproof effect of the docking point.

[0031] The working principle of this utility model is as follows:

[0032] When connecting and installing the busbar trunking body 1 and the busbar trunking body 2, first rotate the connecting pipe ring 71 in the telescopic protection mechanism 7 to connect it with the connecting disc 3 on the busbar trunking body 1, and make the sealing groove ring 72 and the raised sealing ring 4 cooperate. In this way, two sealing lines are formed at the interface, effectively preventing water from seeping in from this part. The same applies to the busbar trunking body 2. First rotate the connecting pipe ring 81 in the telescopic protection mechanism 8 to connect it with the connecting disc 5 on the busbar trunking body 2, and similarly make the sealing groove ring 82 and the raised sealing ring 6 cooperate. Similarly, two sealing lines are formed at the interface, effectively preventing water from seeping in from this part.

[0033] Subsequently, based on the distance between the ends of busbar trunking body 1 and busbar trunking body 2, the telescopic sleeves 73 and 83 are pulled to bring the connecting protective tubes 9 and 11 into contact and lock together. This creates a protective measure between the ends of busbar trunking body 1 and busbar trunking body 2. Then, the silicone rubber sealing ring 121 is fitted between the connecting protective tubes 9 and 11, so that the inner sealing ring groove 122 matches and engages with the convex rings on the back of the connecting protective tubes 9 and 11, forming a radial seal. At the same time, the limiting rings 10 on the outside of the connecting protective tubes 9 and 11 are rotated, so that the limiting rings 10 are embedded in the outer limiting ring grooves 123. In this way, the silicone rubber sealing ring 121 is fixed by the compression of the limiting rings 10. 21 is tightly fitted between the two connecting protective pipes to further enhance the sealing effect and prevent moisture from seeping in from the joint. This forms two sealing lines between the two connecting protective pipes, providing double protection for the waterproof effect at the joint. The other end of the busbar trunking body 1 and the other end of the busbar trunking body 2 are also operated in the same way to form protection. The expansion sleeve 73 and expansion sleeve 83 can be stretched or contracted according to the actual distance between the busbar trunking body 1 and the busbar trunking body 2, without the need for strict and precise control of the installation spacing, reducing the requirements for installation space and dimensional accuracy. It is especially suitable for scenarios with complex on-site environments and spacing errors. At the same time, the components are assembled by threaded connection or snap-fit, which facilitates quick installation, disassembly and maintenance, and improves construction efficiency.

[0034] Multiple sets of fan-shaped heat sinks 13 are symmetrically arranged on the outer side of the first protective pipe 9 and the second protective pipe 11, with some extending into the inside of the pipe body. While ensuring sealing and protection, they can quickly transfer the heat generated by the busbar trunking during operation to the external environment through the heat sinks, thereby achieving heat dissipation and avoiding heat accumulation caused by sealing. This achieves a balance between sealing and waterproofing and heat dissipation, ensuring the long-term stable operation of the busbar trunking.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
