Description

Technical Field

[0001] This application relates to the field of busbar trunking technology, and in particular to a busbar trunking sealing structure. Background Technology

[0002] Busbar trunking is a high-efficiency power transmission device, mainly used in high-current power supply scenarios such as buildings and industrial plants. It consists of a metal shell, conductive busbars, insulation materials and accessories. It can replace traditional cable trays to realize centralized distribution and transmission of electrical energy. Its core advantages are large current carrying capacity, good heat dissipation, convenient installation and maintenance, strong safety protection, and adaptability to complex wiring environments.

[0003] Chinese patent CN217934975U discloses a busbar trunking sealing structure, including a housing composed of multiple sealing side plates and two sets of cover plate assemblies. The cover plate assembly includes a cover plate that can close the housing. The two cover plates are fixed together by bolts, and the bolts are placed on both sides of the housing. This avoids the need to reseal the bolt connection caused by the direct connection of the bolts to the housing, and further reduces the difficulty of sealing. However, in the above patent, the connection and sealing of the cover plate to the housing requires the use of bolts and nuts for locking and fixing. This method is cumbersome and difficult to disassemble quickly. It also requires the use of external tools such as wrenches to complete the disassembly and assembly. This makes the maintenance of the busbar trunking joint time-consuming and laborious, especially in narrow working spaces or emergency maintenance scenarios, affecting maintenance efficiency and failing to meet the needs of convenient operation and maintenance. Therefore, in order to solve the above problems, we provide a busbar trunking sealing structure. Utility Model Content

[0004] The purpose of this utility model is to provide a busbar trunking sealing structure to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions: A busbar trunking sealing structure includes a sealing base plate. Two sealing side plates are fixedly connected to the upper surface of the sealing base plate. A cover plate is provided above the two sealing side plates. Two sets of fixing slots are formed on the upper surface of the cover plate. Two locking and pressure-applying mechanisms are fixedly installed on the opposite sides of the two sealing side plates. A connecting pull plate is provided above the two sets of locking and pressure-applying mechanisms. A connecting plate is fixedly connected to the upper surface of the two sets of connecting pull plates. A fixing block is fixedly connected to the bottom surface of the two sets of connecting plates, and one end of the fixing block extends into the interior of the fixing slot.

[0006] Preferably, a connecting cross plate is fixedly connected to one side of the two sets of connecting plates that are close to each other, and a lifting plate is fixedly connected to one side of the two sets of connecting cross plates that are close to each other. A lifting handle is fixedly connected to the upper surface of the lifting plate. Both locking and pressing mechanisms include supporting recesses. Multiple tension springs are fixedly connected to the inner bottom walls of the two supporting recesses. A sliding pull plate is fixedly connected to the top of each tension spring. The upper surface of the sliding pull plate is fixedly connected to the bottom surface of the connecting pull plate.

[0007] Preferably, a strip plate is fixedly connected to one side of the two connecting pull plates that are close to each other, a sliding sleeve is fixedly connected to one side of each of the two supporting recesses, a positioning slide plate is slidably connected to the inner wall of each of the two sliding sleeves, and the upper surface of each of the two positioning slide plates is fixedly connected to the bottom surface of the strip plate.

[0008] Preferably, two sealing baffles are fixedly connected to the upper surface of the sealing base plate, and multiple conductive bars are fixedly embedded on one side of the two sealing baffles.

[0009] Preferably, the upper surface of the cover plate is fixedly inlaid with multiple aluminum alloy heat-conducting strips, and the outer surface of the sealing base plate is fixedly connected with two sets of fasteners.

[0010] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: This busbar trunking sealing structure allows the fixing block to disengage from the fixing slot simply by pulling the handle upwards. After placing the cover plate, releasing the handle allows the spring to retract and lock the structure in place. The entire process requires no external tools such as wrenches, solving the problems of cumbersome, time-consuming, and labor-intensive disassembly and assembly of traditional sealing structures. In confined working spaces or emergency maintenance scenarios, it can shorten disassembly and assembly time and improve maintenance efficiency. At the same time, the spring provides a continuous and stable tension, ensuring that the fixing block and the fixing slot fit tightly. Combined with the closed design of the cover plate and sealing side plate, it can form a tight sealing cavity, effectively preventing the intrusion of dust, moisture, and other impurities, avoiding abnormal conductivity caused by external environmental influences, and ensuring the long-term stable operation of the busbar trunking.

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0015] Please see Figure 1-5 This utility model provides a technical solution for a busbar trunking sealing structure: A busbar trunking sealing structure includes a sealing base plate 1, with two sealing side plates 2 fixedly connected to the upper surface of the sealing base plate 1. The sealing base plate 1, sealing side plates 2, and sealing baffle 9 are all made of stainless steel, suitable for outdoor, humid, or highly corrosive environments, exhibiting excellent rust resistance and anti-aging capabilities, effectively protecting the internal conductive busbar 10. A cover plate 3 is provided above both the base plate and the two sealing side plates 2. Two sets of fixing slots 12 are provided on the upper surface of the cover plate 3. Two locking and pressure-applying mechanisms 4 are fixedly installed on the opposite sides of the two sealing side plates 2. A connecting pull plate 5 is provided above each set of locking and pressure-applying mechanisms 4. Both sets of connecting plates 5 have a connecting plate 6 fixedly connected to their upper surfaces, and both sets of connecting plates 6 have a fixing block 13 fixedly connected to their bottom surfaces, with one end of the fixing block 13 extending into the inside of the fixing slot 12. Specifically, the cover plate 3, the two sealing side plates 2, and the sealing bottom plate 1 can form a closed protective structure. The two sets of locking and pressure-applying mechanisms 4 provide stable pressure for sealing. During operation, the handle 11 drives the handle plate 8 and the connecting horizontal plate 7, which in turn moves the connecting plate 6 and the connecting plate 5 synchronously, so that the fixing block 13 can be inserted into or removed from the fixing slot 12 of the cover plate 3. Disassembly and assembly can be completed without external tools, improving the ease of operation.

[0016] In this embodiment, a connecting horizontal plate 7 is fixedly connected to one side of the two sets of connecting plates 6 that are close to each other. A lifting plate 8 is fixedly connected to one side of the two sets of connecting horizontal plates 7 that are close to each other. A lifting handle 11 is fixedly connected to the upper surface of the lifting plate 8. Both locking and pressing mechanisms 4 include a support recess 41. Multiple tension springs 42 are fixedly connected to the inner bottom wall of both support recesses 41. A sliding pull plate 43 is fixedly connected to the top of each tension spring 42. The upper surface of the sliding pull plate 43 is fixedly connected to the bottom surface of the connecting pull plate 5. A strip plate is fixedly connected to one side of the two connecting pull plates 5 that are close to each other. 45. Each of the two support recesses 41 has a sliding sleeve 46 fixedly connected to one side. The inner walls of the two sliding sleeves 46 are slidably connected to positioning slide plates 44. The upper surfaces of the two positioning slide plates 44 are fixedly connected to the bottom surface of the strip plate 45. Specifically, multiple tension springs 42 in the support recesses 41 provide continuous tension, which can pull the sliding pull plate 43 to fit tightly with the connecting pull plate 5, ensuring that the fixing block 13 and the fixing slot 12 are firmly engaged. The strip plate 45 and the positioning slide plate 44 slide along the inner wall of the sliding sleeve 46, limiting the movement trajectory of the components, avoiding deviation, making the locking and disassembly process smooth and stable, and extending the service life of the structure.

[0017] In this embodiment, two sealing baffles 9 are fixedly connected to the upper surface of the sealing base plate 1. Multiple conductive bars 10 are fixedly embedded on one side of the two sealing baffles 9. Multiple aluminum alloy heat-conducting strips 14 are fixedly embedded on the upper surface of the cover plate 3. Two sets of fasteners 15 are fixedly connected to the outer surface of the sealing base plate 1. Specifically, the sealing baffles 9 can enhance the sealing of the cavity, prevent impurities from entering, protect the multiple conductive bars 10 embedded inside, and ensure stable conductivity. The aluminum alloy heat-conducting strips 14 on the cover plate 3 can quickly dissipate operating heat to prevent high-temperature failure. The two sets of fasteners 15 on the surface of the sealing base plate 1 can be easily installed and fixed as a whole, adapting to different usage scenarios and achieving multiple needs such as sealing protection, heat dissipation and cooling, and convenient installation.

[0018] Working principle: When the busbar trunking sealing structure is in use, firstly, pull the lifting plate 8 upward by the handle 11, which drives the two sets of connecting horizontal plates 7 and connecting plates 6 to rise synchronously. The fixing block 13 on the bottom of the connecting plate 6 moves upward and disengages from the fixing slot 12 area of ​​the cover plate 3. At this time, the connecting pull plate 5 below the connecting plate 6 pulls the sliding pull plate 43, which stretches and stores the multiple tension springs 42 in the support recess 41. At the same time, the connecting pull plate 5 drives the strip plate 45 and the positioning slide plate 44 to slide upward along the inner wall of the sliding sleeve 46 to ensure smooth overall movement. Then, place the cover plate 3 above the two sealing side plates 2, adjust the position so that the fixing slot 12 is aligned with the bottom of the fixing block 13, and slowly release the handle 11. The tension spring 42 releases its tension and pulls the sliding pull plate 43 downward. The connecting pull plate 5 and the connecting plate 6 drive the fixing block 13 to be embedded in the fixing slot 12. With the continuous tension of the tension spring 42, the cover plate 3 and the sealing side plate 2 are tightly fitted, completing the sealing assembly.

[0019] After assembly, the cover plate 3 and the sealing side plate 2 form a closed cavity, protecting the multiple conductive bars 10 embedded inside from damage and ensuring stable conductivity. Then, the aluminum alloy heat-conducting strip 14 on the cover plate 3 quickly dissipates the internal heat, preventing high temperature from affecting the operation of the equipment. When maintenance and repair are required, there is no need to use tools such as wrenches. Simply pull the handle 11 upwards to drive the fixing block 13 out of the fixing slot 12 and directly remove the cover plate 3 for operation. This is suitable for narrow working spaces or emergency maintenance scenarios.
