Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a waterproof busbar. Background Technology

[0002] Waterproof busbar trunking is a power transmission device specifically designed for humid, water-rich, or easily immersed environments. It achieves physical waterproofing through a high-strength metal shell and a multi-layer sealing structure. Combined with a nano-hydrophobic coating on the conductor surface, epoxy resin casting insulation, and intelligent humidity monitoring technology, it forms a three-dimensional waterproof system from external barrier to internal protection, achieving an IP68 or higher protection level. This ensures long-term stable operation in extreme scenarios such as underground tunnels, coastal facilities, and chemical workshops, while also taking into account heat dissipation performance and convenient maintenance needs.

[0003] Chinese patent CN219833716U discloses a waterproof busbar trunking. This waterproof busbar trunking has a double waterproof structure, which ensures the waterproof performance of the main body of the busbar trunking. It has a good sealing and waterproof effect, and adopts a snap-fit ​​method, which makes it easy to install and disassemble. It is simple to operate, saves time and effort, and has good practicality.

[0004] The aforementioned waterproof busbar trough uses a four-point fixing method to achieve the snap-fit ​​fixing of the upper and lower shells. However, when disassembling, pins need to be inserted into the slots at the four corners, and two pins are needed for each corner. Therefore, eight pins need to be inserted at the same time to complete the disassembly operation. This is not only cumbersome, but also may not be possible for two people to complete the disassembly operation, resulting in low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof busbar trunking, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A waterproof busbar trunking includes a protective shell with copper busbars, a bottom plate at the bottom of the shell, and a top plate at the top. Connecting plates are installed at the four corners of the lower surface of the top plate, and wedge-shaped inserts are installed at the bottom of the connecting plates, with slots on their surfaces. Slots are formed at the four corners of the upper surface of the bottom plate, and wedge-shaped inserts are fitted inside the slots to engage with the slots. A cross groove communicating with the four slots is formed inside the bottom plate, and a cross plate is installed inside the cross groove via an elastic mechanism. The four ends of the cross plate are connected to the four wedge-shaped inserts.

[0008] As can be seen, by pushing the cross plate, the four wedge-shaped blocks can be disengaged from the four slots at the same time, thus releasing the fixation between the top plate and the bottom plate and achieving the purpose of dismantling. The operation is simple, time-saving and labor-saving, and a single person can complete the dismantling operation, making it highly practical.

[0009] Furthermore, the elastic mechanism includes a fixed block installed on the inner wall of the cross groove and a movable block installed on the outer surface of the cross plate. A spring is connected to the outer surface of the movable block, and the end of the spring is connected to the fixed block. The spring applies an elastic thrust to the cross plate to achieve automatic locking.

[0010] Furthermore, a telescopic rod connects the fixed block and the movable block, with a spring fitted onto the outer surface of the telescopic rod. This prevents the spring from bending downwards and deforming under gravity.

[0011] Furthermore, the surface of the base plate has a through groove that communicates with the cross groove, and a sealing plug is installed inside the through groove. This prevents moisture from entering the cross groove and causing corrosion to the spring.

[0012] Furthermore, heat dissipation fins are provided on both sides of the protective shell in the width direction, and comb plates are slidably installed on the two connecting plates on both sides of the top plate in the width direction. The comb plates and heat dissipation fins are interlocked. This allows for easy cleaning of dust adhering to the heat dissipation fins.

[0013] Furthermore, grooves are provided on the upper surface of the base plate and the lower surface of the top plate, with sealing gaskets placed inside the grooves to achieve a waterproof effect.

[0014] Furthermore, the outer surface of the spring is coated with anti-rust paint. This increases the spring's lifespan and prevents damage.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. When the cross plate is pushed, the four wedge-shaped blocks can be disengaged from the four slots at the same time, thus releasing the fixation between the top plate and the bottom plate and achieving the purpose of dismantling. The operation is simple, time-saving and labor-saving, and a single person can complete the dismantling operation. It is highly practical.

[0017] 2. This utility model allows for convenient cleaning of dust adhering to the heat dissipation fins via a sliding comb plate, avoiding the situation where cleaning is difficult due to the small gaps between the heat dissipation fins, leading to the gradual accumulation of dust and reduced heat dissipation effect.

[0026] 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.

[0027] Please see Figures 1-7 This utility model provides a waterproof busbar trunking system, comprising a protective shell 1 with copper busbars 101, a bottom plate 2 at the bottom of the protective shell 1, and a top plate 3 at the top of the protective shell 1. Connecting plates 301 are installed at the four corners of the lower surface of the top plate 3, and wedge-shaped inserts 302 are installed at the bottom of the connecting plates 301. The surface of the wedge-shaped inserts 302 is provided with slots 303. Slots 201 are provided at the four corners of the upper surface of the bottom plate 2, and wedge-shaped inserts 202 that engage with the slots 303 are provided inside the slots 201. A cross groove 203 communicating with the four slots 201 is provided inside the bottom plate 2, and a cross plate 204 is installed inside the cross groove 203 via an elastic mechanism 4. The four ends of the cross plate 204 are respectively connected to the four wedge-shaped inserts 202.

[0028] During installation, the base plate 2 is placed below the protective shell 1, and the top plate 3 is placed above the protective shell 1. The four wedge-shaped inserts 302 are simultaneously inserted into the four slots 201. The inclined surfaces at the ends of the wedge-shaped inserts 302 vertically press against the inclined surfaces of the wedge-shaped locking blocks 202, thereby driving the four wedge-shaped locking blocks 202 to retract simultaneously. When the wedge-shaped inserts 302 are fully inserted into the slots 201 and the slots 303 correspond to the wedge-shaped locking blocks 202, the four wedge-shaped locking blocks 202 can automatically insert into the slots 303 under the action of the elastic mechanism 4, achieving the purpose of automatic locking. The reliability of the connection can be guaranteed by the four-point positioning method.

[0029] When dismantling, simply push the cross plate 204 to cause the four wedge-shaped blocks 202 to simultaneously disengage from the four slots 303, thus releasing the fixation between the top plate 3 and the bottom plate 2 and achieving the purpose of dismantling. The operation is simple, time-saving, and labor-saving, and can be completed by a single person, making it highly practical.

[0030] Preferably, the elastic mechanism 4 includes a fixed block 401 installed on the inner wall of the cross groove 203 and a movable block 402 installed on the outer surface of the cross plate 204. A spring 403 is connected to the outer surface of the movable block 402, and the end of the spring 403 is connected to the fixed block 401.

[0031] When the wedge-shaped insert 302 presses against the wedge-shaped locking block 202, the wedge-shaped locking block 202 is subjected to force and contracts. The wedge-shaped locking block 202 drives the cross plate 204 to slide in the cross groove 203 and compress the spring 403. At this time, the spring 403 is in a stored state. When the locking groove 303 on the wedge-shaped insert 302 corresponds to the wedge-shaped locking block 202, the stored spring 403 releases its elastic force, which can push the cross plate 204 to reset and drive the four wedge-shaped locking blocks 202 to automatically insert into the locking groove 303 for fixation.

[0032] Preferably, a telescopic rod 404 is connected between the fixed block 401 and the movable block 402, and a spring 403 is sleeved on the outer surface of the telescopic rod 404.

[0033] The telescopic rod 404 serves as a guide for the extension and retraction of the spring 403, preventing the spring 403 from bending downwards and deforming under gravity.

[0034] Preferably, the surface of the base plate 2 is provided with a through groove 5 that communicates with the cross groove 203, and a sealing plug 501 is provided inside the through groove 5.

[0035] By inserting the pin into the through groove 5, the cross plate 204 can be slid, achieving the purpose of unlocking and disassembly. Only one pin is needed, and it can be operated by a single person. Furthermore, the through groove 5 can be sealed with the sealing plug 501 to prevent moisture from entering the cross groove 203 and causing corrosion to the spring 403.

[0036] Preferably, heat dissipation fins 102 are provided on both sides of the protective shell 1 in the width direction, and comb plates 304 are slidably installed on the two connecting plates 301 on both sides of the top plate 3 in the width direction, with the comb plates 304 and heat dissipation fins 102 interlocking.

[0037] The heat dissipation fins 102 provide heat dissipation for the protective shell 1. However, after a period of use, dust easily adheres to their surface, which affects their thermal conductivity and reduces the heat dissipation effect. At this time, the dust adhering to each heat dissipation fin 102 can be scraped off by sliding the comb plate 304, thereby achieving the purpose of quick cleaning and avoiding the situation where the gap between the heat dissipation fins 102 is too small, making cleaning difficult and causing dust to gradually accumulate and reduce the heat dissipation effect.

[0038] Preferably, the upper surface of the base plate 2 and the lower surface of the top plate 3 are provided with grooves, and a sealing gasket is provided inside the groove.

[0039] The sealing gaskets ensure the airtightness between the top plate 3 and the bottom plate 2 and the protective shell 1, achieving a waterproof effect.

[0040] Preferably, the outer surface of the spring 403 is coated with anti-rust paint.

[0041] Since the spring 403 is located inside the cross groove 203 and is not easy to replace, its corrosion resistance can be significantly improved by coating its surface with anti-rust paint, thereby increasing its service life and preventing damage.

[0042] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
