Description

Technical Field

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

[0002] Cast busbar trunking is made of high-performance insulating resin and various inorganic minerals. The cast busbar trunking directly casts and seals the busbars, achieving an IP68 protection level. It is a new type of metal-free busbar trunking with four protection functions: waterproof, fireproof, corrosion-proof, and explosion-proof.

[0003] Chinese utility model patent CN215120023U discloses a castable waterproof busbar trunking, comprising an epoxy resin sealed shell. Busbar clamps are provided at both the top and bottom of the epoxy resin sealed shell, and fixing blocks are provided on both sides of the busbar clamps. A conical limiting block is provided at the bottom of each fixing block, and the conical limiting block is inserted into the bottom wall of the epoxy resin sealed shell. Slots are provided on the busbar clamps, and conductive copper busbars are inserted between the slots where the two busbar clamps are aligned. Elastic locking blocks are provided on both sides of the inner wall of the slots, and the two ends of the conductive copper busbars are clamped and fixed by the elastic locking blocks. In this utility model, by casting the busbar clamps and conductive copper busbars into the epoxy resin sealed shell, a seal is formed, thereby improving the waterproof performance of the busbar trunking and ensuring that the conductive copper busbars and busbar clamps do not shift during casting, avoiding the situation where the busbar trunking is scrapped due to displacement.

[0004] However, the following problems were found in the implementation of the relevant technology: maintenance and repair are difficult. The integrated casting structure makes the internal conductive busbar and the insulating material tightly bonded. Once a fault occurs or a part needs to be replaced, the outer shell cannot be easily disassembled for repair. The casting layer needs to be cut or peeled off for repair. After repair, it needs to be recast, which is time-consuming and labor-intensive, increasing maintenance costs and time. Utility Model Content

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] Please see Figure 1 - Figure 6 Highly waterproof cast-in-place busbar trunking includes:

[0032] The epoxy resin sealed housing 1, the copper busbar 2 mounted on the epoxy resin sealed housing 1, and the plug box 3 disposed above it;

[0033] A first U-shaped shell 4 and a second U-shaped shell 5 are arranged in a rectangular shape with the top and bottom symmetrically arranged. The first U-shaped shell 4 is located inside the second U-shaped shell 5. An epoxy resin sealing shell 1 is located inside the first U-shaped shell 4 and the second U-shaped shell 5 arranged in a rectangular shape. A plug-in box 3 is fixedly installed on the top of the second U-shaped shell 5.

[0034] Multiple inclined drainage channels 6 are provided on the second U-shaped shell 5, and the multiple inclined drainage channels 6 are arranged in a straight line;

[0035] And a fixing component 7 sleeved on the outside of the first U-shaped shell 4 and the second U-shaped shell 5, wherein the first U-shaped shell 4 and the second U-shaped shell 5 are fixed to the epoxy resin sealing shell 1 by the fixing component 7.

[0036] The highly waterproof cast busbar trunking provided by this utility model is used in which the first U-shaped shell 4 and the second U-shaped shell 5 are fixed to the epoxy resin sealing shell 1 by the fixing component 7. With the cooperation of the first U-shaped shell 4 and the second U-shaped shell 5, the waterproof effect can be further improved. After the busbar trunking is repaired, the epoxy resin sealing shell 1 does not need to be repaired and cast as a whole, saving maintenance costs and time. Finally, with the cooperation of the inclined drainage channel 6, the drainage performance can be effectively increased, ensuring that water will not accumulate on the busbar trunking, thereby effectively improving the waterproof performance.

[0037] Furthermore, protective sleeves 10 are fitted on both ends of the epoxy resin sealing housing 1, and the protective sleeves 10 are located between the first U-shaped housing 4 and the second U-shaped housing 5. Sealing gaskets 11 are fixedly installed on both the inner and outer walls of the protective sleeves 10.

[0038] Specifically, when manually installing the first U-shaped shell 4 and the second U-shaped shell 5, the protective sleeve 10 is first placed on the epoxy resin sealing shell 1, and then, with the cooperation of the sealing gasket 11, the sealing effect between the first U-shaped shell 4, the second U-shaped shell 5 and the epoxy resin sealing shell 1 can be improved, thereby further improving the waterproof effect.

[0039] Furthermore, the fixing component 7 includes a fixing frame 71 sleeved on the outside of the second U-shaped shell 5, and a pair of T-shaped rods 72 are fixedly installed on both the left and right sides of the fixing frame 71, and a connecting bracket 73 is provided on each pair of T-shaped rods 72.

[0040] A pair of plug-in rods 74 and a pair of springs 75 are fixedly installed on one side of the connecting frame 73, and the other end of the spring 75 is fixedly connected to the fixed frame 71. The other end of the plug-in rod 74 passes through one side wall of the fixed frame 71 and is plugged into the round hole that is connected to the first U-shaped shell 4 and the second U-shaped shell 5.

[0041] Specifically, after the fixing frame 71 is manually placed in the designated position of the second U-shaped shell 5, since the front end of the plug rod 74 is not blocked by the second U-shaped shell 5, the compressed and deformed spring 75 opens and resets, driving the connecting bracket 73 on the T-shaped rod 72 to move. This allows the end of the plug rod 74 away from the connecting bracket 73 to be inserted into the circular hole communicating with the first U-shaped shell 4 and the second U-shaped shell 5, thereby fixing the first U-shaped shell 4 and the second U-shaped shell 5 onto the epoxy resin sealing shell 1.

[0042] Furthermore, both the upper and lower ends of the fixed frame 71 are provided with transmission mechanisms, and the two connecting frames 73 are connected to each other through the transmission mechanisms.

[0043] Specifically, through the transmission mechanism, when a person pulls the connecting frame 73 on one side of the fixed frame 71, the connecting frame 73 on the other side can move synchronously, thereby making the fixed frame 71 easy to assemble and disassemble.

[0044] Furthermore, the transmission mechanism includes a fixed rod 12 fixedly mounted on the fixed frame 71, a gear 13 fixedly mounted on the outer side wall of the fixed rod 12, and a pair of racks 14 fixedly mounted on one side of each of the two connecting frames 73, and the racks 14 on the two connecting frames 73 are meshed with the gears 13.

[0045] Specifically, when the connecting frame 73 on one side of the fixed frame 71 is pulled manually, the connecting frame 73 drives the gear 13 on the fixed rod 12 to rotate through the rack 14 on it. Then, the rotating gear 13, through the rack 14 that meshes with it on another connecting frame 73, can drive the other connecting frame 73 away from the second U-shaped shell 5 and pull the plug rod 74 out of the round hole. Thus, the manual only needs to pull the connecting frame 73 on one side, and the plug rods 74 on both sides of the fixed frame 71 can be pulled out of the plugging round hole, which is convenient for disassembling the fixed component 7.

[0046] Example 2

[0047] Based on Embodiment 1, in this embodiment: a pair of strip grooves 8 are provided on both sides of the first U-shaped shell 4, and a pair of strip plates 9 are fixedly installed on both sides of the inner wall of the second U-shaped shell 5, and the strip plates 9 are inserted into the strip grooves 8.

[0048] The technical solution provided in this embodiment is as follows: when the second U-shaped shell 5 is manually inserted into the outside of the first U-shaped shell 4, the strip plate 9 on the second U-shaped shell 5 is inserted into the strip groove 8 on the first U-shaped shell 4. This allows the first U-shaped shell 4 and the second U-shaped shell 5 to be initially fixed on the epoxy resin sealing shell 1, freeing the workers' hands, facilitating the installation of the fixing component 7, and improving the waterproof effect between the first U-shaped shell 4 and the second U-shaped shell 5.

[0049] 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, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
