Description

Technical Field

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

[0002] A waterproof bus duct is a high-performance power transmission device with excellent waterproof and corrosion resistance properties. It is designed with special insulating materials and a tightly laminated structure, enabling it to operate normally in humid or underwater environments. Moreover, once installed, it requires no maintenance. In addition, it has a high protection level, can withstand power frequency withstand voltage, and has a low temperature rise, ensuring the stable and safe operation of the power system.

[0003] Existing waterproof bus ducts can prevent moisture from seeping in and damaging the internal wires and circuits. However, during the installation process, the corresponding copper sheets between two bus ducts need to be connected through connectors and conductive sheets. Due to the gradually decreasing stability of the copper sheets on both sides of the bus duct from the bus duct to the ends of the copper sheets, the ends of the copper sheets are more likely to shake under the influence of external forces. Therefore, during installation, it is necessary to accurately align the copper sheets with the spacer sheets on the connectors, which is time-consuming during this adjustment process and reduces the usability of the waterproof bus duct. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a waterproof bus duct to solve the technical problem that it is difficult to accurately align the copper sheets when they are likely to shake under the influence of external forces.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A waterproof bus duct includes a housing and a connection mechanism. Installation shells are provided on both sides of the connection mechanism. A plurality of spacer sheets are provided on the two installation shells. Vertical sheets are provided at the bottoms of the spacer sheets. Inclined surfaces are provided on both sides of the vertical sheets. The bottoms of the inclined surfaces and the bottoms of the spacer sheets form a triangular structure.

[0006] By adopting the above technical solution, turning the fastening bolts to make the connection mechanism in a relaxed state provides a convenient starting condition for the implementation of the utility model. Subsequently, aligning the positions of the triangular structure formed by the inclined surface and the bottom of the spacer sheet with the gap between adjacent copper sheets simplifies the complexity of alignment. At the same time, after pressing the spacer sheet, using the guiding function of the inclined surface, the spacer sheet can be inserted smoothly and accurately between the copper sheets, achieving fast and stable connection. During this process, the tight fit between the conductive sheet and the copper sheet also ensures the continuity of power transmission. In addition, to address the problem of the gradually decreasing stability of the copper sheets on both sides of the bus duct, by first inserting the copper sheet closer to the bus duct side and then gradually inserting the spacer sheet into the gap between adjacent copper sheets, the stability of the copper sheets during the insertion process is effectively improved.

[0007] Furthermore, the length dimensions of the two inclined surfaces are consistent. A copper sheet is disposed through the interior of the housing, and mounting sheets are provided on both sides of the copper sheet.

[0008] By adopting the above technical solution, it ensures that the spacer can maintain stability and symmetry when inserted into the copper sheet, improving the accuracy and stability of the insertion. At the same time, this design also simplifies the manufacturing and installation processes because all inclined surfaces can be processed according to the same specifications, reducing production costs and operational complexity.

[0009] Furthermore, an upper protective shell is provided at the top of the connecting mechanism, and a lower protective shell is provided at the bottom of the connecting mechanism. Both the upper protective shell and the lower protective shell are in a "U" - shaped structure.

[0010] By adopting the above technical solution, the "U" - shaped structure can provide more comprehensive protection. This structure enables the protective shell to closely surround the connecting mechanism, effectively preventing external factors such as dust and moisture from invading, thereby protecting the internal electrical connections from damage and improving the overall safety.

[0011] Furthermore, mounting holes are provided at the tops of both the upper protective shell and the lower protective shell. The mounting holes are used to provide mounting positions for the upper protective shell and the lower protective shell.

[0012] By adopting the above technical solution, it provides convenience for installation. Through these mounting holes, the upper protective shell and the lower protective shell can be easily fixed in the predetermined positions, simplifying the installation process and improving the installation efficiency.

[0013] Furthermore, the material of the spacer is insulating polyvinyl chloride, and the spacers are distributed in the gaps between adjacent copper sheets, enhancing the connection stability of the busbar chute.

[0014] By adopting the above technical solution, the insulating polyvinyl chloride has corrosion resistance and can remain stable in various environments, thereby extending the service life of the busbar chute. Moreover, it provides good electrical safety. The insulating material can effectively isolate adjacent copper sheets, preventing abnormal current flow, thus reducing the risk of electrical faults and protecting the stable operation of the busbar chute system.

[0015] Furthermore, a conductive sheet is provided on one side of the spacer, and the conductive sheet is in contact with the copper sheet.

[0016] By adopting the above technical solution, the conductivity of the busbar chute is enhanced. The conductive sheet is in close contact with the copper sheet, ensuring that current can smoothly conduct from one copper sheet to another, reducing resistance and energy loss, and improving the efficiency of power transmission.

[0017] Furthermore, multiple spacers and conductive sheets are connected through two groups of fastening bolts passing through them.

[0018] By adopting the above technical solution, the stability of the overall structure is improved. The fastening bolts can ensure the tight connection between various components, effectively preventing loosening and displacement, thereby guaranteeing the stability and safety of the busbar connection.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] 1. Through the inclined plane of the utility model, first turn the fastening bolt to make the connecting mechanism in a relaxed state, then align the triangular structure composed of the inclined plane and the spacer with the gap of the copper sheet, which simplifies the alignment process. After pressing the spacer, the inclined plane guides the spacer to be completely inserted into the copper sheet, realizing rapid connection. At the same time, the connection stability is enhanced. Since the stability of the copper sheets on both sides of the busbar gradually decreases and the ends of the copper sheets are prone to shaking, the triangular structure is used to preferentially insert the copper sheet closer to the busbar side, and then gradually insert the spacer into the gap of the adjacent copper sheet, effectively improving the stability of the copper sheet during the insertion process, thereby enhancing the overall connection stability and reliability.

[0021] 2. By setting the upper protective shell and the lower protective shell, the utility model can provide effective physical protection for the busbar connecting mechanism. They can prevent external objects from directly contacting the connecting mechanism, reducing safety risks caused by accidental collisions or damages. At the same time, the upper protective shell and the lower protective shell can also play a role in dust prevention and waterproofing. They can block environmental factors such as dust and moisture from entering the inside of the connecting mechanism, thereby ensuring the stability and reliability of the electrical connection. This protection mechanism extends the service life of the busbar system and reduces the failure rate caused by environmental factors. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Embodiment 1:

[0032] A waterproof busbar trunking, such as Figures 1 - 4As shown in the figure, it includes a housing 1 and a connecting mechanism 7. Installation shells 701 are provided on both sides of the connecting mechanism 7. A plurality of spacers 702 are provided on the two installation shells 701. A vertical piece 704 is provided at the bottom of the spacer 702. Inclined surfaces 705 are provided on both sides of the vertical piece 704. The bottom of the inclined surface 705 and the bottom of the spacer 702 form a triangular structure. By turning the fastening bolt 703, the connecting mechanism 7 is in a relaxed state, providing a convenient starting condition for the implementation of the present invention. Subsequently, the triangular structure formed by the inclined surface 705 and the bottom of the spacer 702 is aligned with the gap between the adjacent copper sheets 3 in terms of position, simplifying the complexity of alignment. At the same time, after pressing the spacer 702, by using the guiding effect of the inclined surface 705, the spacer 702 can be smoothly and accurately inserted between the copper sheets 3, achieving fast and stable connection. During this process, the close fit between the conductive sheet 8 and the copper sheet 3 also ensures the continuity of power transmission. In addition, aiming at the problem that the stability of the copper sheets 3 on both sides of the busbar groove gradually decreases, by preferentially inserting the copper sheet 3 close to one side of the busbar groove and then gradually inserting the spacer 702 into the gap between the adjacent copper sheets 3, the stability of the copper sheets 3 during the insertion process is effectively improved. This step-by-step stable insertion method not only improves the convenience of connection, but also enhances the firmness and reliability of the overall structure.

[0033] Refer to Figure 3 , Figure 4 , the length dimensions of the two inclined surfaces 705 are the same. The copper sheet 3 is penetrated through the housing 1. Installation pieces 2 are provided on both sides of the copper sheet 3. This ensures that the spacer 702 can remain stable and symmetric when inserted into the copper sheet 3, improving the accuracy and stability of the insertion. At the same time, this design also simplifies the manufacturing and installation processes because all the inclined surfaces 705 can be processed according to the same specifications, reducing the production cost and operation complexity. At the same time, the copper sheet 3 is penetrated through the housing 1. Installation pieces 2 are provided on both sides of the copper sheet 3. This structure enables the copper sheet 3 to be firmly installed in the housing 1 and is not prone to shaking or displacement, thus ensuring the stability and safety of power transmission. The existence of the installation piece 2 further enhances the fixing effect of the copper sheet 3 and improves the reliability of the overall structure.

[0034] Embodiment Two:

[0035] Refer to Figure 1, a top protective housing 4 is provided at the top of the connecting mechanism 7, and a bottom protective housing 5 is provided at the bottom of the connecting mechanism 7. Both the top protective housing 4 and the bottom protective housing 5 are in a "U" - shaped structure. The "U" - shaped structure can provide more comprehensive protection. This structure enables the protective housing to closely surround the connecting mechanism 7, effectively preventing external factors such as dust and moisture from invading, thereby protecting the internal electrical connections from damage and improving the overall safety. At the same time, the "U" - shaped structure also enhances the overall stability. The top protective housing 4 and the bottom protective housing 5 can closely fit the connecting mechanism 7, reducing the possibility of shaking and loosening, ensuring the stability and reliability of the busbar connection. In addition, the "U" - shaped structure also makes installation and maintenance more convenient, facilitating the installation, repair, and replacement work for operators.

[0036] Refer to Figure 1 , mounting holes 6 are provided at the top of both the top protective housing 4 and the bottom protective housing 5. The mounting holes 6 are used to provide mounting positions for the top protective housing 4 and the bottom protective housing 5, facilitating the installation. Through these mounting holes 6, the top protective housing 4 and the bottom protective housing 5 can be easily fixed in the predetermined positions, simplifying the installation process and improving the installation efficiency. At the same time, the mounting holes 6 also make the fixation of the top protective housing 4 and the bottom protective housing 5 more firm and stable. Through appropriate fasteners such as screws, the protective housing can be tightly fixed to the connecting mechanism, preventing it from loosening or shifting during use, thus ensuring the effective protection of the connecting mechanism 7 by the protective housing, which is both convenient for installation and enhances the structural stability.

[0037] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the spacer 702 is made of insulating polyvinyl chloride, and the spacer 702 is distributed in the gaps between adjacent copper sheets 3, improving the connection stability of the busbar. The insulating polyvinyl chloride has corrosion resistance and can remain stable in various environments, thereby extending the service life of the busbar. And it provides good electrical safety. The insulating material can effectively isolate adjacent copper sheets, preventing abnormal current flow, thus reducing the risk of electrical faults and protecting the stable operation of the busbar system. At the same time, the spacer 702 is distributed in the gaps between adjacent copper sheets 3, which significantly improves the connection stability of the busbar. The spacer 702 not only fills the gaps between the copper sheets 3, reducing the shaking of the copper sheets 3, but also enhances the overall mechanical strength through its structural design, enabling the busbar to maintain a stable connection when subjected to external forces or temperature changes, ensuring the continuity and reliability of power transmission.

[0038] Refer to Figure 2 , Figure 3 , Figure 4, on one side of the spacer 702, a conductive sheet 8 is provided. The conductive sheet 8 is in contact with the copper sheet 3, enhancing the conductivity of the busbar. The conductive sheet 8 is in close contact with the copper sheet 3, ensuring that current can flow smoothly from one copper sheet to another, reducing resistance and energy loss, and improving the efficiency of power transmission. At the same time, the contact between the conductive sheet 8 and the copper sheet 3 also improves the stability of the connection. The contact setting makes it difficult for the conductive sheet 8 and the copper sheet 3 to loosen or have poor contact. Even in an environment of vibration or temperature change, a stable electrical connection can be maintained, thus ensuring the reliability and safety of the busbar system.

[0039] Refer to Figure 2 , Figure 3 , Figure 4 , a plurality of spacers 702 and conductive sheets 8 are connected through two groups of fastening bolts 703, improving the stability of the overall structure. The fastening bolts 703 can ensure the tight connection between each component, effectively preventing loosening and displacement, thus guaranteeing the stability and safety of the busbar connection. At the same time, this connection method also simplifies the installation and maintenance process. By using the fastening bolts 703, the installation, disassembly, and replacement of components can be conveniently carried out, improving work efficiency. In addition, the through connection also makes the entire structure more compact, reducing space occupancy, which is beneficial to achieving efficient power transmission in a limited space.

[0040] The implementation principle of the present utility model is as follows: When connecting two busbars, first loosen the nut on the fastening bolt 703 to make the fastening bolt 703 loose. Then, align the bottom of the inclined surface 705 and the bottom of the spacer 702 to form a triangular structure with the gap between the corresponding adjacent copper sheets 3. After that, press the spacer 702. At this time, the inclined surface 705 will guide the spacer 702, making the spacer 702 completely inserted into the copper sheet 3, and at the same time, the conductive sheet 8 is in contact with the copper sheet 3. During this insertion process, it is beneficial to improve the insertion convenience of the connecting mechanism 7 and the two groups of busbars. As Figure 2 shown, the stability of the copper sheets 3 on both sides of the busbar gradually decreases from the busbar to the end of the copper sheet 3. Therefore, the end of the copper sheet 3 is more likely to shake under the influence of external forces. At this time, through the above insertion process, the triangular structure can be used to preferentially insert the side of the copper sheet 3 close to the busbar. As the insertion progresses gradually, the spacer 702 is gradually inserted into the gap between the adjacent copper sheets 3, thereby improving the stability of the copper sheet 3 during the insertion process and enhancing the connection convenience with the external connecting mechanism 7.

[0041] Parts not involved in the present utility model are the same as or can be implemented using existing technologies, and will not be elaborated here.
