Description

Technical Field

[0001] This utility model relates to the field of power busbar technology, and in particular to a power busbar that is easy to maintain. Background Technology

[0002] In power transmission systems, busbars serve as crucial carriers connecting power distribution and consumption equipment, and their operational stability, ease of maintenance, and protective performance directly impact the reliability of power supply. However, traditional power busbars suffer from numerous technical challenges in practical applications, making it difficult to meet the demands for efficient operation and maintenance as well as long-term stable operation.

[0003] On the one hand, the covers of traditional busbar trunking often use complex connection methods such as bolt fixing. When it is necessary to inspect the copper busbars inside the box, it is necessary to use professional tools such as wrenches to remove the bolts one by one. Not only is the disassembly process cumbersome and time-consuming, but it is also easy to cause subsequent assembly difficulties due to lost bolts or stripped threads, which seriously affects the maintenance efficiency and increases the risk of power supply interruption due to shutdown maintenance. It is difficult to ensure the timely maintenance and stable operation of the copper busbars.

[0004] On the other hand, the protective structure design of traditional busbar trunking has shortcomings. Although some busbar trunking systems are equipped with dustproof components, these are mostly fixed structures. After long-term use, dust easily accumulates on the surface of these components, requiring the disassembly of a large number of parts for cleaning, which is inconvenient and ineffective. At the same time, traditional busbar trunking lacks an effective buffer structure. When subjected to external impacts, the impact force acts directly on the enclosure and core components such as internal copper busbars and insulating blocks, which can easily lead to deformation or damage of these components, shortening the service life of the busbar trunking and increasing the cost of later maintenance and replacement.

[0005] Therefore, it is necessary to propose a power busbar trunking system that is easy to maintain in order to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a power busbar trunking that is easy to maintain, so as to solve the technical shortcomings of traditional power busbar trunking in terms of maintenance convenience, protection performance and heat dissipation effect mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power busbar trunking that is easy to maintain, comprising a box body, an insulating block fixedly installed inside the box body, a copper busbar fixedly connected inside the insulating block, a slot opened inside the top of the box body, a plug inserted inside the slot, a positioning groove opened on the side of the plug, and a cover plate frame fixedly connected to the top of the plug.

[0008] A disassembly assembly is provided on the side of the housing near the slot. The disassembly assembly includes a positioning sleeve, a positioning rod, and a first spring. The side of the positioning sleeve is fixedly connected to the side of the housing, and the inside of the positioning sleeve is slidably connected to the outside of the positioning rod. One end of the positioning rod extends movably into the inside of the slot and is inserted into the positioning groove. The side of the inner cavity of the positioning sleeve is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to the outside of the positioning rod. A limit hole is formed inside the positioning rod.

[0009] Preferably, the positioning rod passes through and extends to the outside of the positioning sleeve, and a handle is fixedly connected to the end of the positioning rod away from the slot.

[0010] Preferably, a second spring is fixedly connected to the bottom of the inner cavity of the cover frame, and a dustproof plate is fixedly connected to the top of the second spring.

[0011] Preferably, there are four second springs, which are located at the four corners of the bottom of the cover plate frame cavity.

[0012] Preferably, the outer surface of the dustproof plate is slidably connected to the inner wall of the cover frame.

[0013] Preferably, both the cover frame and the dustproof plate have multiple heat dissipation holes inside, and the top of the dustproof plate is covered with a dustproof net.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting up a disassembly assembly, when the copper busbar needs to be inspected, pulling the handle causes the positioning rod to slide in the positioning sleeve and compress the first spring. The positioning rod disengages from the positioning groove of the insert block, allowing the cover frame connected to the insert block to be removed, exposing the copper busbar inside the box. After inspection, the insert block is inserted into the slot, the positioning rod is released, and the first spring pushes the positioning rod back to its original position and engage with the positioning groove, completing the fixation of the cover frame. This process requires no complicated tools, shortens disassembly and installation time, reduces operational difficulty, makes copper busbar inspection more convenient, and reduces the impact of maintenance downtime on power supply. Furthermore, when the limiting hole inside the positioning rod is pulled out of the positioning sleeve, a pin can be inserted into the limiting hole to position the positioning rod, preventing the first spring from causing the positioning rod to reset.

[0016] 2. By setting up a cover frame, a second spring, and a dustproof plate, the dustproof plate inside the cover frame can prevent external dust and impurities from entering the enclosure, thus avoiding them from affecting the conductivity of the copper busbars or damaging internal components; the second springs at the four corners of the cover frame can buffer the impact force through their own deformation when the busbar trunking is subjected to external impact, reducing the impact damage to the cover frame and the copper busbars and insulating blocks inside the enclosure. The combination of the two not only keeps the inside of the enclosure clean, but also reduces the damage caused by external impact, extends the overall service life of the busbar trunking, and reduces the later maintenance costs.

[0017] 3. The ventilation holes in the cover frame and dustproof plate allow for air convection, effectively dissipating heat generated by the copper busbars inside the enclosure. This prevents overheating from affecting the performance of the copper busbars or causing malfunctions, ensuring the safe operation of the busbar trunking. When the dustproof screen accumulates excessive dust, first remove the cover frame. Because the dustproof plate is connected to the cover frame via a second spring and can slide, applying force to the dustproof plate will cause the spring to deform and then return to its original position, causing the dustproof plate to vibrate at a high frequency and small amplitude. This vibration is transmitted to the dustproof screen, breaking the adhesion of the dust and causing it to fall off quickly. The spring also prevents the dustproof plate from colliding and damaging the cover frame. After cleaning, the dustproof plate returns to its original position via the spring, and the cover frame can be reinstalled. The entire process is efficient and convenient.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1 - Figure 6The diagram shows a power busbar trunking system that is easy to maintain. It includes a housing 1, an insulating block 2 fixedly installed inside the housing 1, a copper busbar 3 fixedly connected inside the insulating block 2, a slot 4 opened inside the top of the housing 1, a plug 5 inserted into the slot 4, a positioning groove 6 opened on the side of the plug 5, and a cover frame 11 fixedly connected to the top of the plug 5. A disassembly assembly is provided on the side of the housing 1 near the slot 4. The disassembly assembly includes a positioning sleeve 7, a positioning rod 8 and a first spring 9. The side of the positioning sleeve 7 is fixedly connected to the side of the housing 1, and the inside of the positioning sleeve 7 is slidably connected to the outside of the positioning rod 8. One end of the positioning rod 8 extends movably into the inside of the slot 4 and is inserted into the positioning groove 6. The side of the inner cavity of the positioning sleeve 7 is fixedly connected to one end of the first spring 9, and the other end of the first spring 9 is fixedly connected to the outside of the positioning rod 8. A limit hole 10 is opened inside the positioning rod 8.

[0027] When the copper busbar 3 needs to be repaired, pull the handle of the positioning rod 8 away from the slot 4; the positioning rod 8 slides in the positioning sleeve 7 and compresses the first spring 9, and the end of the positioning rod 8 that extends into the slot 4 disengages from the positioning groove 6 of the plug block 5; the cover frame 11 fixed with the plug block 5 is taken out from the slot 4 at the top of the box 1, exposing the copper busbar 3 and the insulating block 2 inside the box 1 for repair; after the repair is completed, the plug block 5 is inserted into the slot 4, the positioning rod 8 is released, the first spring 9 pushes the positioning rod 8 to reset, and it is inserted into the positioning groove 6 to fix the cover frame 11, restoring the busbar trunking to operation. When the limiting hole 10 inside the positioning rod 8 is pulled out of the positioning sleeve 7, a pin can be inserted into the limiting hole 10 to position the positioning rod 8, preventing the first spring 9 from causing the positioning rod 8 to reset.

[0028] In addition, a second spring 13 is fixedly connected to the bottom of the inner cavity of the cover frame 11, and a dustproof plate 14 is fixedly connected to the top of the second spring 13. There are four second springs 13, which are located at the four corners of the bottom of the inner cavity of the cover frame 11. The outer side of the dustproof plate 14 is slidably connected to the inner wall of the cover frame 11. Multiple heat dissipation holes 12 are opened inside both the cover frame 11 and the dustproof plate 14. A dustproof net is laid on the top of the dustproof plate 14. The copper busbar 3 generates heat when it is powered on, and the heat is diffused into the interior of the housing 1. The heat dissipation holes 12 of the cover frame 11 and the dustproof plate 14 form an air convection channel to dissipate the heat inside the housing 1 to the outside, maintain the stable temperature inside the housing 1, and prevent the copper busbar 3 from overheating. At the same time, the dustproof net on the top of the dustproof plate 14 prevents external dust from entering the housing 1, protecting the copper busbar 3 and the insulating block 2 from dust. The second spring 13 buffers the impact force of the outside on the cover frame 11 and the dustproof plate 14 through its own elasticity, reducing the risk of component damage.

[0029] Finally, when the dustproof mesh on the top of the dustproof plate 14 accumulates too much dust, repeat the steps in the maintenance process of the copper busbar 3 (pull the positioning rod 8 and take out the cover frame 11); apply external force to the dustproof plate 14 in the inner cavity of the cover frame 11, and the dustproof plate 14 causes the second spring 13 to deform; remove the external force, and the second spring 13 returns to its original position, causing the dustproof plate 14 to vibrate at high frequency. The vibration is transmitted to the dustproof mesh, breaking the adhesion of the dust and causing the dust to fall off quickly; after cleaning, the dustproof plate 14 returns to its original position under the action of the second spring 13; insert the plug 5 into the slot 4, and the positioning rod 8 is inserted into the positioning groove 6 under the action of the first spring 9 to fix the cover frame 11, and the dustproof mesh restores its dustproof function.

[0030] Working principle: During normal operation, after the copper busbar 3 is powered on and generates heat, the heat is dissipated through the heat dissipation holes 12 of the cover frame 11 and the dustproof plate 14 to maintain the temperature stability inside the box 1. The dustproof net on the top of the dustproof plate 14 blocks dust, and the second spring 13 buffers external force to protect the components. When the copper busbar 3 needs to be repaired, pull the handle of the positioning rod 8 so that one end is disengaged from the positioning groove 6 of the insert 5 (the positioning rod 8 slides in the positioning sleeve 7 and compresses the first spring 9). After the cover frame 11 is removed for repair, insert the insert 5 into the slot 4, and release the positioning rod 8 so that it resets and fixes the cover frame 11 under the action of the first spring 9. When the dustproof net is too dusty, remove the cover frame 11 according to the above steps, apply force to the dustproof plate 14 to deform the second spring 13, and after the force is released, the second spring 13 drives the dustproof plate 14 to vibrate and let the dust fall off. After cleaning, reset the dustproof plate 14 and re-fix the cover frame 11.
