Description

Technical Field

[0001] This utility model relates to the field of electrical engineering and power transmission and distribution technology, and in particular to a busbar trunking connection device. Background Technology

[0002] Busbar trunking, as the core power distribution device of high-current power transmission and distribution systems, is widely used in industrial plants, commercial buildings, and other scenarios. It is responsible for the transmission and distribution of electricity. The busbar trunking body is generally equipped with plug-in interfaces on the side or front for wiring and docking with various electrical equipment such as generator boxes and plug-in boxes. The protection capability of the interfaces is directly related to the stability and safety of power transmission and distribution operation. The existing busbar trunking interfaces are mostly protected by a single flap structure, which only normally blocks the interface with a single flap. When carrying out wiring work or equipment maintenance, the flap must be fully opened before operation can be carried out. The sealing performance of this protective structure is significantly insufficient. The fit gap between the single flap and the interface is large, making it difficult to form an effective airtight protection. During long-term use, external dust can easily enter through the gaps and accumulate at the plug-in interface, causing dust accumulation in the internal conductive parts, which in turn can lead to short circuit faults. This directly affects the normal operation of the internal circuit components of the busbar trunking, reduces the operational reliability of the power transmission and distribution system, and shortens the overall service life of the equipment.

[0003] In existing technologies, when the busbar trunking needs to be connected to electrical equipment such as generator boxes or plug-in boxes, the wiring connection is usually made through the plug-in interface on its side or front. In existing equipment, the plug-in interface is protected by a single flap that is normally blocked, and needs to be fully opened during use or maintenance, resulting in poor sealing. In addition, the traditional single flap is closed by gravity or simple hinge, and the gaps are easy for dust and water to enter. Furthermore, the traditional method requires the flap to be fully opened during maintenance, which leads to a large amount of external impurities entering and causing secondary pollution.

[0004] To address this, a busbar trunking connection device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a busbar trunking connection device that can solve the problems of short circuit risk caused by insufficient sealing and the contradiction between maintenance convenience and impurity control.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a busbar trunking connection device, comprising a busbar trunking body, a plug-in interface movably connected to the front side of the busbar trunking body, a sealing and dustproof mechanism movably connected to the front side of the busbar trunking body, the sealing and dustproof mechanism being disposed on the outside of the plug-in interface, and a flexible maintenance mechanism movably connected to the inside of the sealing and dustproof mechanism. The sealing and dustproof mechanism includes a sealing box fixedly connected to the front side of the busbar trunking body. The sealing box is located on the outside of the plug interface. A sealing cover is rotatably connected to the left side of the sealing box. An elastic sealing block is fixedly connected to the outside of the sealing cover. A sealing groove is opened on the front side of the sealing box. The elastic sealing block is stuck inside the sealing groove. A detachable cleaning component is movably connected to the rear side of the sealing cover.

[0007] Preferably, the flexible maintenance mechanism includes a support shaft movably connected to the front side of the sealing cover, a flip cover fixedly connected to the outer side of the support shaft, and the flip cover movably connected to the inner side of the sealing cover.

[0008] Preferably, a first torsion spring is fixedly connected to the top of the flip cover, and the first torsion spring is fixedly connected to the top of the outer side of the support shaft.

[0009] Preferably, self-locking grippers are provided on both sides of the support shaft, and a support rod is rotatably connected to the outer side of the self-locking gripper. The support rod is fixedly connected to the bottom of the support shaft, and a second torsion spring is fixedly connected to the outer side of both the support rod and the self-locking gripper.

[0010] Preferably, the detachable cleaning assembly includes a sliding rail fixedly connected to the rear side of the sealing cover, the sliding rail being fixedly connected to both sides of the rear side of the sealing cover, and a cleaning adhesive plate being slidably connected to the inner side of the sliding rail.

[0011] Preferably, a travel groove is provided on each side of the sliding rail, a telescopic rod is fixedly connected to the inner side of the travel groove, a linkage lever is fixedly connected to the outer side of the telescopic rod, a compression spring is fixedly connected to the linkage lever and the side of the travel groove, a pressing block is fixedly connected to each side of the telescopic rod, and the linkage lever is movably connected to the inner side of the sliding rail.

[0012] Preferably, the top of the sealing cover is fixedly connected to a first positioning magnet.

[0013] Preferably, a second positioning magnet is fixedly connected to the top of the sealed box, and the first positioning magnet is located on the front side of the second positioning magnet.

[0014] Preferably, the front side of the flip cover is movably connected to a fastener.

[0015] Preferably, an anti-slip pad is fixedly connected to the outer side of the extrusion block.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This application solves the limitations of traditional single-flip panels by setting up a sealing and dustproof mechanism. Previously, single-flip panels relied on gravity or simple hinges to close, which did not close tightly and allowed dust and water to enter through the gaps, resulting in poor sealing. Now, with a sealing box on the outside and an elastic sealing block on the front sealing cover, it can be tightly locked into the sealing groove when closed, sealing the gaps tightly and making it difficult for dust and water to enter, greatly improving the sealing performance. Moreover, under normal conditions, the cleaning adhesive plate on the inside of the sealing cover can absorb impurities in the sealing box. It can be quickly replaced according to the degree of dirt during maintenance. During installation, the new adhesive plate is pushed into the sliding rail and the pressing block will be elastically fixed. When removing, the linkage lever can be pressed to slide it out, which is convenient and quick, avoiding the entry of impurities during maintenance, reducing the risk of internal short circuits, and making the bus trunking more durable. 2. This application addresses the limitations of traditional flip-type maintenance by setting up a flexible maintenance mechanism. Traditional maintenance requires fully opening the flip-type, leading to a large influx of external impurities and causing secondary pollution. Now, each connector has an independent flip cover located inside the sealing cover. When no overall maintenance is needed, simply rotate the flip cover on the front of the corresponding connector for individual use. Before opening the flip cover, manually press the self-locking claws on both sides of the support shaft to release the restriction on the support shaft. Flip the flip cover and rotate it along the axis. After adjusting the opening and closing range according to usage requirements, release the self-locking claws. The second torsion spring on the outer side rebounds and locks the support shaft to fix the opening and closing range. After use, press the self-locking claws again to release the restriction. The elastic potential energy accumulated by the first torsion spring around the support shaft is released, causing the flip cover to close quickly, shortening the opening and closing time. This avoids full opening and closing, reduces the influx of external air and impurities, and solves the problem of secondary pollution. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-6 The present invention provides the following technical solution: A busbar trunking connection device includes a busbar trunking body 1, a plug-in interface 2 movably connected to the front side of the busbar trunking body 1, a sealing and dustproof mechanism 3 movably connected to the front side of the busbar trunking body 1, the sealing and dustproof mechanism 3 being disposed on the outside of the plug-in interface 2, and a flexible maintenance mechanism 4 movably connected to the inside of the sealing and dustproof mechanism 3. The sealing and dustproof mechanism 3 includes a sealing box 31 fixedly connected to the front side of the bus trunking body 1. The sealing box 31 is located on the outside of the plug interface 2. A sealing cover 32 is rotatably connected to the left side of the sealing box 31. An elastic sealing block 33 is fixedly connected to the outside of the sealing cover 32. A sealing groove 34 is opened on the front side of the sealing box 31. The elastic sealing block 33 is stuck inside the sealing groove 34. A detachable cleaning component 35 is movably connected to the rear side of the sealing cover 32.

[0021] In this embodiment: Previously, when connecting the busbar trunking 1 to electrical equipment such as generator boxes and plug-in boxes, wiring was typically done through the side or front plug-in interface 2. However, older equipment used a single flap to normally cover the plug-in interface 2, requiring it to be fully opened when in use. This resulted in poor sealing, dust accumulation, and potential short circuits, affecting the busbar trunking's circuit components. A new method has been adopted: a sealing box 31 has been added to the outside of the plug-in interface 2, directly blocking external air and impurities. A sealing cover 32 further covers the opening of the sealing box 31. To maintain the entire plug-in interface 2, the sealing cover 32 is rotated to open the sealing box 31. It can be operated with 1. When the cover is closed, the elastic sealing block 33 on the outside of the sealing cover 32 will be squeezed into the sealing groove 34, sealing the gap between the sealing cover 32 and the sealing box 31. Normally, there is a cleaning sticky plate 35b on the inside of the sealing cover 32 facing the sealing box 31, which is supported by the sliding rail 35a. It can stick to the impurities inside the sealing box 31 and prevent too much dirt from getting in during maintenance. Moreover, each time maintenance is performed, the cleaning sticky plate 35b on the back of the sealing cover 32 can be easily replaced by the detachable cleaning component 35. This cleaning sticky plate 35b sticks to and sucks away the dust and impurities in the sealing box 31.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the flexible maintenance mechanism 4 includes a support shaft 41 movably connected to the front side of the sealing cover 32, a flip cover 42 fixedly connected to the outside of the support shaft 41, and the flip cover 42 movably connected to the inside of the sealing cover 32.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, a first torsion spring 43 is fixedly connected to the top of the flip cover 42, and the first torsion spring 43 is fixedly connected to the top of the outer side of the support shaft 41.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, self-locking grippers 44 are provided on both sides of the support shaft 41. A support rod 45 is rotatably connected to the outer side of the self-locking gripper 44. The support rod 45 is fixedly connected to the bottom of the support shaft 41. A second torsion spring 46 is fixedly connected to the outer side of both the support rod 45 and the self-locking gripper 44.

[0025] In this embodiment: when connecting or repairing a single connector 2 without needing to maintain the entire sealing cover 32, it is not necessary to open the entire sealing cover 32. Simply rotate the flip cover 42 located inside the sealing cover 32 on the front side of the corresponding connector 2 to achieve single-port use. Before opening the flip cover 42, the opening and closing range of the flip cover 42 can be adjusted according to the intended use. This prevents a large amount of outside air and impurities from entering after the flip cover 42 is fully opened. Specifically, first, manually press the self-locking claws 44 located at the rotation point of the flip cover 42, i.e., on both sides of the supporting shaft 41, to release the self-locking claws 44 from limiting the supporting shaft 41. Then, flip the flip cover 42, allowing it to rotate along the axis via the supporting shaft 41. Following this, according to daily inspection, maintenance, and connection... For different opening needs such as operation, select the appropriate opening range, and then release the self-locking claw 44. When the self-locking claw 44 is pressed, the second torsion spring 46 between the outer side of the self-locking claw 44 rotation point and the support rod 45 will be tightened. Therefore, after releasing, the second torsion spring 46 will quickly rebound, allowing the self-locking claw 44 to lock the support shaft 41 and restrict the rotation of the support shaft 41, thereby maintaining the current opening and closing range. After use, press the self-locking claw 44 again to release its restriction on the rotation of the support shaft 41. Since the first torsion spring 43 on the outer side of the support shaft 41 has accumulated the elastic potential energy of rotation when the flip cover 42 was rotated before, the first torsion spring 43 will quickly rebound after the self-locking claw 44 is released, causing the flip cover 42 to close quickly, shortening the opening and closing time.

[0026] Specifically, such as Figure 3 , Figure 4 As shown, the detachable cleaning assembly 35 includes a sliding rail 35a fixedly connected to the rear side of the sealing cover 32. The sliding rail 35a is fixedly connected to both sides of the rear side of the sealing cover 32, and a cleaning adhesive plate 35b is slidably connected to the inner side of the sliding rail 35a.

[0027] Specifically, such as Figure 3 , Figure 4 As shown, a travel groove 35c is provided on one side of the sliding rail 35a. A telescopic rod 35d is fixedly connected to the inner side of the travel groove 35c. A linkage lever 35e is fixedly connected to the outer side of the telescopic rod 35d. A compression spring 35f is fixedly connected to the side of the linkage lever 35e and the travel groove 35c. A pressing block 35g is fixedly connected to the side of the telescopic rod 35d. The linkage lever 35e is movably connected to the inner side of the sliding rail 35a.

[0028] In this embodiment, when replacing the cleaning adhesive plate 35b according to its adhesion, the operation process is as follows: First, remove the contaminated cleaning adhesive plate 35b, then take the cleaning adhesive plate 35b to be replaced, and insert its upper and lower sides into the inner side of the sliding rail 35a. Then, push it inward to install it. During the process of pushing the cleaning adhesive plate 35b inward, it will squeeze the squeezing block 35g inside the sliding rail 35a, causing the squeezing block 35g to retract into the travel groove 35c that does not affect the sliding of the cleaning adhesive plate 35b. When the squeezing block 35g retracts, it will press the telescopic rod 35d between itself and the inner wall of the travel groove 35c, as well as the compression spring 35f on the outside of the telescopic rod 35d. At the same time, through... The linkage lever 35e causes multiple pressing blocks 35g inside the sliding rail 35a to move together. When the cleaning adhesive plate 35b slides to the bottom of the sliding rail 35a, the sliding installation is completed. At this time, the pressing blocks 35g, which have accumulated elastic potential energy in the multiple stroke grooves 35c inside the sliding rail 35a at the top and bottom of the cleaning adhesive plate 35b, will contact and press the cleaning adhesive plate 35b from multiple positions above and below, fixing it in place by elastic force. This makes the installation quick and easy. If it is necessary to remove the cleaning adhesive plate 35b, simply press the linkage lever 35e at the top or bottom end to release the pressing blocks 35g from locking the cleaning adhesive plate 35b, and then slide it off directly.

[0029] Specifically, such as Figure 1 , Figure 2 As shown, a first positioning magnet 5 is fixedly connected to the top of the sealing cover 32.

[0030] Specifically, such as Figure 1 , Figure 2 As shown, a second positioning magnet 6 is fixedly connected to the top of the sealing box 31, and a first positioning magnet 5 is located in front of the second positioning magnet 6.

[0031] In this embodiment, the first positioning magnet 5 and the second positioning magnet 6 can improve the degree of closure between the sealing cover 32 and the sealing box 31, thereby enhancing the sealing performance.

[0032] Specifically, such as Figure 1 As shown, a fastener 7 is movably connected to the front side of the flip cover 42.

[0033] Specifically, such as Figure 3 As shown, an anti-slip pad 8 is fixedly connected to the outer side of the extrusion block 35g.

[0034] In this example: the latch 7 makes it easy to open the flip cover 42, and the anti-slip pad 8 increases the clamping friction of the squeezing block 35g.

[0035] Working Principle: When the busbar trunking 1 needs to connect to electrical equipment such as generator boxes or plug-in boxes, the wiring connection is usually made through the plug-in interface 2 on its side or front. In existing equipment, the plug-in interface 2 is protected only by a single flap that is normally covered, and needs to be fully opened during use or maintenance. This results in poor sealing and dust accumulation at the plug-in interface 2, which can cause internal short circuits and affect the internal circuit components of the busbar trunking. The traditional single flap storage method is no longer used. Instead, a sealing box 31 is set on the outside of the plug-in interface 2 to directly block the outside air and impurities. A sealing cover 32 is set on the front side of the sealing box 31 to cover the front opening of the sealing box 31. When it is necessary to maintain the plug-in interface 2, the sealing cover 32 is rotated to open the seal. When the box 31 is unsealed for maintenance, the elastic sealing block 33 on the outside of the sealing cover 32 will press and lock into the inside of the sealing groove 34 to seal the gap between the sealing cover 32 and the sealing box 31. Under normal conditions, a cleaning adhesive plate 35b supported by a sliding rail 35a is provided on the inside of the sealing cover 32 facing the sealing box 31. The cleaning adhesive plate 35b will adhere to and absorb impurities inside the sealing box 31, preventing excessive impurities from overflowing into the sealing box 31 during maintenance. Furthermore, the cleaning adhesive plate 35b can be quickly replaced according to its adhesion condition during each maintenance operation. After removing the contaminated cleaning adhesive plate 35b, remove the cleaning adhesive plate 35b to be replaced and lock it into the inside of the sliding rail 35a. The cleaning adhesive plate 35b is pushed inward for installation. During this inward movement, it compresses the pressing block 35g located inside the sliding rail 35a, causing it to retract into the travel groove 35c that does not affect the sliding of the cleaning adhesive plate 35b. During this retraction, the pressing block 35g presses against the telescopic rod 35d and its outer compression spring 35f between itself and the inner wall of the travel groove 35c. The multiple pressing blocks 35g inside the sliding rail 35a are simultaneously activated by the linkage lever 35e. After the cleaning adhesive plate 35b slides to the bottom, it not only completes the sliding installation but also features multiple travel grooves 35c and pressing blocks 35g with continued elastic potential energy inside the top and bottom sliding rails 35a. These pressing blocks contact and compress the cleaning adhesive plate 35b from multiple points above and below, elastically fixing it in place. This allows for quick installation. When removal is required, the linkage lever 35e at the top or bottom end engages with the clamping block 35g, allowing for direct sliding removal. When only connection work or individual repair of a single connector 2 is needed without overall maintenance, the entire sealing cover 32 does not need to be opened. Simply rotate the flip cover 42 located inside the sealing cover 32 on the front side of the corresponding connector 2 to enable single-port use. Before opening the flip cover 42, the opening angle can be adjusted according to the intended use to prevent excessive air and impurities from entering. Before opening the flip cover 42, manually press the self-locking claws 44 located on both sides of the support shaft 41 at the rotation point of the flip cover 42. This releases the self-locking claws 44 from limiting the support shaft 41.The flip cover 42 is flipped so that it rotates along the axis via the support shaft 41. After selecting an appropriate opening range according to the needs of opening the cover, such as daily inspection, maintenance, or connection work, the pressure on the self-locking claw 44 is released. During the previous pressing, the second torsion spring 46 between the outer side of the self-locking claw 44's rotation point and the support rod 45 is tightened, causing it to quickly rebound and lock the support shaft 41, restricting its rotation and maintaining the opening / closing range. After use, the self-locking claw 44 is pressed again to release the rotation restriction on the support shaft 41. During the previous rotation, the first torsion spring 43 on the outer side of the support has accumulated rotational elastic potential energy, so it will quickly rebound after the self-locking claw 44 is released, causing the flip cover 42 to close rapidly, shortening the opening and closing time. In summary, this optimizes the routine maintenance and daily use of the front insertion interface 2 of the busbar trunking body 1.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
