Description

Technical Field

[0001] The utility model belongs to the technical field of bus ducts, and particularly relates to a positioning and plugging structure of a waterproof bus duct. Background Technique

[0002] As a core component of the power transmission system, the waterproof performance of the bus duct is directly related to the safety and reliability of the equipment in harsh environments such as humid and dusty conditions. Especially in fields such as chemical industry, underground engineering, and outdoor power distribution, the sealing structure of the bus duct needs to have long-term stable waterproof ability to avoid safety hazards such as short circuits and corrosion caused by water seepage.

[0003] Currently, the industry generally adopts a gluing process to achieve waterproof sealing. For example, high-quality imported sealant is applied at the connection between the socket and the plug box, or a continuous sealant strip is formed by a fully automatic dispensing machine. Although such a process can ensure the sealing effect in the short term, significant defects are exposed in the long-term operation:

[0004] First, the colloid is prone to aging and cracking under the influence of temperature fluctuations, mechanical stress, etc., resulting in a gradual degradation of the sealing performance;

[0005] Second, the adhesion of the sealant strip to the metal surface is restricted by the interface cleanliness and curing conditions. If the construction accuracy is insufficient, micro-gaps are likely to occur, forming a potential water seepage hazard;

[0006] Third, the existing plugging structure lacks a precise positioning design. During installation, it relies on manual alignment, and plugging deviation is likely to occur, which not only exacerbates the local stress of the sealant but also may cause problems such as poor contact and abnormal temperature rise;

[0007] Therefore, it is necessary to design a positioning and plugging structure of a waterproof bus duct to solve the above problems. Content of the Utility Model

The connection holes 2 and the connection part of the bus bar groove are sealed by the sealing strip B8, and the connection holes 2 and the connection part of the plug-in box are sealed by the sealing strip A4, so as to ensure better sealing effect during connection.

[0047] Embodiment 2: Please refer to Figures 1 to 10As shown, on the basis of the first embodiment, the present utility model provides a technical solution: The sealing strip A4 includes a main strip 9. An airbag cavity 10 is arranged inside the main strip 9, and the airbag cavity 10 is filled with an elastic silica gel material, which expands when pressed to enhance the sealing fit. The structure of the sealing strip B8 is the same as that of the sealing strip A4. The sealing strip A4 is used for the seal between the socket 1 and the plug-in box, and the sealing strip B8 is used for the seal between the socket 1 and the busbar housing 17. The two sides of the socket 1 are sealed by the main strip 9. An installation insert bar 12 is arranged on one side of the main strip 9, and an installation groove 11 is formed on the surface of the socket 1. The installation insert bar 12 is installed inside the installation groove 11. During use, the installation is more stable through the engagement of the installation insert bar 12 and the installation groove 11. A push bar 15 is fixedly installed inside the main strip 9, and a compression spring 13 is fixedly installed inside the installation insert bar 12. One end of the compression spring 13 is provided with a sliding block 14. One side of the push bar 15 presses tightly on the sliding block 14.

[0048] Adopting the above technical solution, during use, the main strip 9 fits on the busbar trough and the plug-in box, and the airbag cavity 10 ensures a tighter fit when stressed. At the same time, the push bar 15 pushes the sliding block 14 to press on the compression spring 13, and the compression spring 13 pushes the installation insert bar 12 to engage in the installation groove 11, ensuring that the main strip 9 is more tightly and stably installed and used.

[0049] Further, refer to Figures 1 to 10 , the heat dissipation mechanism 19 includes ventilation boxes 40 installed at both ends of the busbar housing 17 and a connecting box 41 installed between the ventilation boxes 40. A ventilation fan 43 is installed inside the ventilation box 40, and a filter element 42 is arranged inside the connecting box 41. The lower side of the ventilation box 40 is connected to the inside of the busbar housing 17 through an opening. By operating the ventilation fan 43, an air flow is generated inside the busbar housing 17 to carry the heat to other positions and cooperate with the heat dissipation fins 32 to dissipate heat outward, thus avoiding the phenomenon of local overheating. At the same time, the filter element 42 filters impurities, and can clean the inside of the busbar housing 17 to a certain extent to reduce the impact on the busbar body 30.

[0050] Further, refer to Figures 1 to 10The busbar housing 17 includes a mounting plate 27 and a protective side plate 28 mounted on one side of the mounting plate 27. A heat sink 32 is provided on one side of the protective side plate 28. A sealing gasket 31 is provided at the connection between the mounting plate 27 and the protective side plate 28. When in use, the airflow of the heat dissipation mechanism 19 and the heat sink 32 are used to accelerate heat dissipation, and the sealing gasket 31 is used to strengthen the housing seal; the inner surface of the mounting plate 27 and the outer surface of the protective side plate 28 are both provided with snap-fitting corrugations 29, and the snap-fitting corrugations 29 on the mounting plate 27 and the protective side plate 28 are snap-fitted with each other. When in use, the snap-fitting corrugations 29 are snap-fitted to ensure that the connection between the mounting plate 27 and the protective side plate 28 is stable.

[0051] The working principle and use process of the utility model are as follows: when in use, the plug socket 1 is installed on one side of the bus duct through the connecting hole 2, the plug-in card seat 22 is installed on the inner side of the plug socket 1 through the positioning frame 7, and the plug-in positioning port 3 is conveniently positioned to install the plug-in box plug on the plug-in card seat 22, the plug-in box is positioned through the positioning protrusion 5, the two sides of the plug-in seat 1 are sealed through the sealing strip A4 and the sealing strip B8, and the bulging of the airbag cavity 10 is coordinated to ensure a better sealing effect, and the support of the push strip 15 pushes the sliding block 14 to press on the compression spring 13 when under force, so that the compression spring 13 pushes the installation plug strip 12 to engage in the installation groove 11 more stably, ensuring that the main strip 9 is more stable and more tightly sealed when in use;

[0052] During installation, the power board 24 is inserted between the busbar bodies 30 in the busbar housing 17, and the upper end of the push pressure frame 34 is supported between the power board 24, thereby ensuring that the connection between the power board 24 and the busbar body 30 is more stable, and the partition plate 36 separates the busbar body 30 and supports the support plate 35 to ensure that the busbar body 30 is installed more stably, and cooperates with the support bar 37 and the support frame 38 to support the push pressure frame 34, ensuring that the push pressure frame 34 is more stable during installation and use. When the plug-in box condenses on the outside of the plug-in socket 1, it is plugged between the connecting spring pieces 23. When in use, heat is generated at the connection of the power board 24, resulting in excessive heat. The ventilation fan 43 is operated to generate airflow in the busbar housing 17 to bring the heat to other positions to cooperate with the heat sink 32 to dissipate heat outward, thereby avoiding the phenomenon of local overheating. At the same time, the filter element 42 filters impurities, and the busbar housing 17 can be cleaned to a certain extent to reduce the impact on the busbar body 30.
