Description

Technical Field

[0001] This utility model belongs to the field of power transmission, and in particular relates to a water-guiding and protective shell for a waterproof busbar trunking. Background Technology

[0002] Busbar trunking, as an efficient and reliable power transmission solution, is widely used in various industrial and commercial buildings. It distributes electrical energy from the power source to various electrical devices through enclosed channels made of metal or insulating materials. Compared to traditional cable distribution methods, busbar trunking has advantages such as high current carrying capacity, convenient installation, and small space occupation, making it particularly suitable for large-scale facilities requiring high-volume power transmission.

[0003] However, in practical applications, especially in outdoor environments or humid conditions, traditional busbar trunking has revealed some significant problems. Particularly when the busbar trunking is installed vertically, openings are often required at connection points or where it passes through walls to facilitate connections or passage. These openings easily become pathways for rainwater intrusion, leading to damage to internal electrical components, short circuits, or even more serious safety accidents. For example, during the rainy season or in high-humidity environments, surface runoff may flow along the outside of the busbar trunking and directly into the openings, eventually seeping into the interior.

[0004] While some waterproofing measures exist on the market, such as the use of sealing tape and waterproof coatings, these methods typically offer only limited protection, and their effectiveness gradually diminishes over time due to material aging and other factors. Furthermore, these temporary solutions are not suitable for all types of joints or wall penetrations, proving inadequate for waterproofing needs in complex environments. Utility Model Content

[0005] The purpose of this utility model is to provide a water-guiding and protective shell for a waterproof busbar trunking, which prevents rainwater from entering the busbar trunking by collecting and guiding surface rainwater.

[0006] To achieve the above objectives, the specific technical solution of the waterproof busbar trunking water guiding and protective shell of this utility model is as follows:

[0007] A water-guiding and protective outer shell for a waterproof busbar trunking is provided, which encloses the busbar trunking housing and surrounds the housing with a water-guiding structure.

[0008] The flow guiding structure includes a first flow guiding channel, a second flow guiding channel and a third flow guiding channel connected to both ends of the first flow guiding channel, and a fourth flow guiding channel communicating with the second flow guiding channel and the third flow guiding channel; the first flow guiding channel, the second flow guiding channel, the third flow guiding channel and the fourth flow guiding channel are arranged around the shell, the second flow guiding channel and the third flow guiding channel are inclined downward from the first flow guiding channel, the two ends of the fourth flow guiding channel are connected to the inclined lower ends of the second flow guiding channel and the third flow guiding channel, and the fourth flow guiding channel is provided with a discharge end, the discharge end discharging the liquid collected by the flow guiding structure.

[0009] As a further improvement of this utility model, the first guide groove, the second guide groove, the third guide groove and the fourth guide groove are respectively inclinedly disposed on the surface of the housing.

[0010] As a further improvement of this utility model, the flow guiding structure is detachably mounted on the housing.

[0011] As a further improvement of this utility model, a connecting groove is provided around the surface of the housing, and the first flow guide groove, the second flow guide groove, the third flow guide groove and the fourth flow guide groove are respectively inserted into the connecting groove to realize a detachable connection on the surface of the housing.

[0012] As a further improvement of this utility model, the first guide channel, the second guide channel, the third guide channel and the fourth guide channel are in the shape of protruding on both sides and concave in the middle. The protruding parts on both sides are respectively the connecting wall connected to the shell and the guide wall on the side away from the shell.

[0013] As a further improvement of this utility model, the housing is rectangular, and L-shaped connecting grooves are provided on the four sides respectively. The connecting wall is a right-angle bend that matches the connecting groove, and the connecting wall is inserted into the corresponding connecting groove from the side of the housing.

[0014] As a further improvement of this utility model, the two ends of the fourth guide groove are inclined towards the discharge end.

[0015] As a further improvement of this utility model, the fourth guide channel includes a left channel and a right channel, which are respectively inserted into the connecting channel and inclinedly connected to the discharge end from top to bottom.

[0016] As a further improvement of this utility model, the two ends of the first guide channel cover the upper ends of the second guide channel and the third guide channel, and the lower ends of the second guide channel and the third guide channel cover the upper ends of the two ends of the fourth guide channel.

[0017] Beneficial effects:

[0018] The outer casing features a flow-guiding structure surrounding it, consisting of a first, second, third, and fourth flow-guiding channel. These channels surround the casing, with the second and third channels angled downwards from the first. The fourth channel connects to the lower angled ends of the second and third channels, and includes a discharge end. This design allows the first channel to quickly collect rainwater on the busbar surface. The second and third channels, utilizing their angled structure, rapidly guide the rainwater to the fourth channel, ultimately discharging it through the discharge end. This prevents rainwater from entering the busbar interior, effectively avoiding short-circuit faults and metal corrosion caused by rainwater intrusion, ensuring the safe and stable operation of the busbar, and improving power transmission reliability. Furthermore, the angled arrangement of each channel on the casing surface further optimizes the rainwater flow path, reduces rainwater residue within the flow-guiding structure, and enhances flow efficiency.

[0019] The flow guiding structure is detachably mounted on the housing. Specifically, it is detachably connected by connecting grooves arranged around the housing surface, allowing the first, second, third, and fourth flow guiding grooves to be inserted into the connecting grooves. This design enables construction personnel to quickly and easily install the flow guiding structure onto the busbar housing during installation, without the need for complex tools or cumbersome operations, reducing installation difficulty and time costs. Furthermore, during later maintenance or replacement of the flow guiding structure, it can be easily disassembled for convenient inspection, repair, or replacement, effectively reducing maintenance costs and extending the overall service life of the busbar.

[0020] The first, second, third, and fourth guide channels are shaped with protruding sides and a concave center. The protruding sides are respectively the connecting wall that connects to the shell and the guide wall on the side away from the shell. When the shell is rectangular, L-shaped connecting channels are provided on each of the four sides. The connecting wall and the bottom surface are bent at right angles to match the connecting channel. The connecting wall is inserted into the corresponding connecting channel from the side of the shell. This structural design ensures a tight connection between the guide channel and the shell, enhancing the stability of the guide structure and preventing loosening or detachment during long-term use. Furthermore, the tight connection further improves the sealing performance, effectively preventing rainwater from seeping in at the connection between the guide structure and the shell, thus further ensuring the waterproof effect of the busbar trunking.

[0021] The fourth guide channel is inclined at both ends towards the discharge end, and includes a left channel and a right channel, which are inserted from the connecting channel and inclined downwards to the discharge end. This design allows rainwater in the fourth guide channel to flow more smoothly towards the discharge end, avoiding water accumulation and ensuring that rainwater can be discharged quickly and completely. At the same time, the two ends of the first guide channel cover and connect to the upper ends of the second and third guide channels, and the lower ends of the second and third guide channels cover and connect to the upper ends of the fourth guide channel. This covering connection method further optimizes the overall sealing and guiding performance of the guide structure, prevents rainwater leakage at the guide channel connection, and comprehensively protects the busbar trunking from rainwater intrusion.

[0027] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0028] Implementation example:

[0029] like Figure 1-4 The waterproof busbar trunking shown has a water-guiding and protective shell. When the busbar trunking vertically passes through a wall, an opening is required to enable connection and passage. To prevent rainwater from accumulating and entering the busbar trunking, a water-guiding structure 2 is provided on the outside of the busbar trunking shell 1 to collect and discharge rainwater.

[0030] The flow guiding structure 2, by setting a flow guiding channel around the rectangular shell, collects rainwater from all sides and discharges it into the rainwater pipe through the drainage end. The flow guiding channel has an inverted U-shaped structure, with the connecting walls 211 and the flow guiding wall 212 on both sides extending vertically upward from the bottom surface. The shell 1 is provided with connecting grooves 11 around the perimeter corresponding to the flow guiding structure. The connecting grooves 11 are L-shaped and protrude through both sides of the shell 1, corresponding to the shape of the connecting walls 211. The flow guiding channel is conveniently and detachably installed on the shell 1 by inserting it from the side through the connecting grooves 11. The insertion connection between the flow guiding channel and the connecting grooves 11 also prevents rainwater from seeping out through the gap between the flow guiding channel and the shell.

[0031] The flow guiding structure 2 has a first flow guiding channel 21, a second flow guiding channel 22, a third flow guiding channel 23, and a fourth flow guiding channel 24 respectively arranged around the shell 1. All are inclined from top to bottom and connected end to end to facilitate rainwater collection. The first flow guiding channel 21 connects to the second flow guiding channel 22 and the third flow guiding channel 23 at both ends, extending outwards and covering the upper ends where the second and third flow guiding channels 22 and 23 connect. The lower end of the second flow guiding channel 22 covers the upper end of the left channel 241 of the fourth flow guiding channel, and the lower end of the third flow guiding channel 23 covers the upper end of the right channel 242 of the fourth flow guiding channel, preventing rainwater seepage at the connection point. In the fourth flow guiding channel 24, the left channel 241 and the right channel 242 are inclined towards the discharge end 243, ensuring that the collected rainwater is uniformly collected at the discharge end 243, from which the rainwater is discharged into the rainwater pipe.

[0032] This invention utilizes a multi-layered flow-guiding structure composed of multiple flow-guiding channels to effectively guide rainwater falling on the shell surface to a safe location for discharge. This design ensures that even under severe weather conditions, the impact of moisture on the busbar trunking is minimized. The flow-guiding structure features a detachable design for easy installation and maintenance. The connecting groove design allows for easy insertion or removal of each flow-guiding channel, simplifying the initial installation process and facilitating subsequent cleaning and replacement. All flow-guiding channels are designed with specific inclination angles, especially the fourth flow-guiding channel, whose ends are inclined towards the discharge end, ensuring that water flows quickly and smoothly to the designated drainage area, preventing water accumulation and further enhancing waterproof performance. The L-shaped connecting groove and the right-angle bent connecting wall design not only strengthen the connection between the flow-guiding structure and the shell but also improve the overall sealing and stability. Furthermore, the design of the protruding parts on both sides (connecting wall and flow-guiding wall) helps increase flow-guiding efficiency while reducing the risk of rainwater infiltration. The rectangular shell and the L-shaped connecting grooves on its four sides allow the protective shell to be flexibly adjusted according to the actual installation environment, adapting to the requirements of various complex terrains and building structures. Meanwhile, the downward-sloping connection of the left and right busbars increases design flexibility. By effectively preventing moisture intrusion, corrosion and aging caused by dampness are reduced, significantly extending the service life of the busbar trunking and its protective casing. This not only lowers long-term operating costs but also improves the reliability and safety of the power transmission system. The waterproofing measures of this invention significantly reduce the risk of short circuits and other electrical faults caused by moisture intrusion, providing users with a safer and more reliable power transmission solution.
