Description

Technical Field

[0001] This utility model relates to the technical field of busbar equipment, and in particular to a dustproof and waterproof sealed busbar. Background Technology

[0002] Busbar trunking, as a key component of power transmission systems, is widely used in industrial plants, commercial complexes, underground utility tunnels, data centers, and other locations. With the increasing complexity of modern industrial environments and the growing number of outdoor power consumption scenarios, higher demands are being placed on the dustproof and waterproof performance of busbar trunking.

[0003] Traditional busbar trunking typically employs static sealing structures, such as fixed sealing strips or a single epoxy resin casting process. During long-term use, factors such as thermal expansion and contraction due to environmental temperature changes and equipment vibration can cause the sealing components to deform, crack, or loosen, creating gaps that allow dust, rainwater, and other substances to easily penetrate the busbar trunking, thus affecting its normal operating requirements.

[0004] Therefore, it is necessary to provide a dustproof and waterproof sealed busbar trunking to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a dustproof and waterproof sealed busbar trunking, which solves the problem that static sealing structures are prone to loosening of sealing components under the influence of factors such as thermal expansion and contraction and equipment vibration, thus affecting the waterproof and dustproof properties of the trunking.

[0006] To solve the above-mentioned technical problems, the present invention provides a dustproof and waterproof sealed busbar trunking, comprising: a trunking structure, a cover plate structure that slides on the top of the trunking structure for sliding sealing, a positioning baffle assembly provided on the inner wall of the trunking structure, a telescopic transmission assembly provided in the middle of the positioning baffle assembly, sliding sealing assemblies installed at both ends of the telescopic transmission assembly for position sealing of the trunking structure, and an elastic sealing assembly installed at the bottom of one end of the sliding sealing assembly for elastic sealing between the sliding sealing assembly and the trunking structure.

A structural component is installed on the inner wall of the support block. The cover plate structure includes a sliding groove and a fixed cover plate. The sliding groove is opened at the top of both ends of the groove structure. Fixed handles are provided at both ends of the fixed cover plate for fixing the position of the cover plate to slide. Slider blocks are installed at the bottom of both ends of the fixed cover plate.

[0008] Preferably, the positioning baffle assembly includes a positioning vertical groove, and a positioning baffle slides inside the positioning vertical groove for installing the workpiece of the telescopic transmission assembly. Positioning blocks are provided at both ends of the positioning baffle.

[0009] Preferably, the telescopic transmission assembly includes a fixed plate, a reverse-threaded rod is provided between the inner walls of the side ends of the fixed plate, a threaded slider is threadedly connected to the inner wall of the reverse-threaded rod, a rotating frame is installed on the side ends of the threaded slider and the sliding sealing assembly, and a first connecting bracket and a second connecting bracket are rotatably connected to the side ends of the rotating frame for rotatable connection between the threaded slider and the sliding sealing assembly.

[0010] Preferably, the sliding sealing assembly includes a slope groove and a sliding sealing frame. The slope groove is formed on the inner walls of both ends of the groove structure for sliding sealing of the sliding sealing frame. Limiting rods are provided at both ends of the sliding sealing frame for positioning and sliding of the sliding sealing frame.

[0011] Preferably, the elastic sealing assembly includes an elastic reset member, which is installed at the bottom of both ends of the sliding sealing assembly.

[0012] Compared with related technologies, the dustproof and waterproof sealed busbar trunking provided by this utility model has the following advantages:

[0013] Beneficial effects:

[0014] This utility model provides a dustproof and waterproof sealed busbar trunking. During daily use, to improve the overall sealing effect of the trunking, a telescopic transmission component and a sliding sealing component work together. During the rotation and tightening of the telescopic transmission component, the sliding sealing components at both ends automatically adjust their sealing position and tightness according to the actual gap size at both ends. Even if the distance between the trunking ends changes due to thermal expansion and contraction or installation errors, a tight fit is always maintained, and the force is evenly distributed during tightening, preventing localized incomplete sealing. Simultaneously, as the sliding sealing components at both ends slide, the elastic sealing component at the bottom deforms, filling any tiny gaps between the sliding sealing components and the bottom of the trunking, forming a secondary seal and further improving the overall waterproof and dustproof performance of the trunking.

[0023] The groove structure 1 includes a groove workpiece 11. A support block 12 is installed on the inner wall of the groove workpiece 11 for supporting the internal structure of the groove structure 1. A structural component 13 is installed on the inner wall of the support block 12. The cover plate structure 2 includes a sliding groove 21 and a fixed cover plate 22.

Fixed handles 23 are provided at both ends of the fixed cover plate 22 for fixing the position of the cover plate 22 to slide. Slider 24 is installed at the bottom of both ends of the fixed cover plate 22.

[0024] During installation and use, the cable tray structure 1 is conveniently installed and disassembled by the workers through the top sliding fixed cover plate 22, so as to inspect and maintain the structure and provide convenience for use.

[0025] Among them, the wire trough structure 1 includes, but is not limited to, metal wire trough, plastic wire trough, and composite wire trough; in this embodiment, the wire trough structure 1 is preferably a composite wire trough.

[0026] The positioning baffle assembly 3 includes a positioning vertical groove 31, and a positioning baffle 32 slides inside the positioning vertical groove 31 for installing the workpiece of the telescopic transmission assembly 4. Positioning blocks 33 are provided at both ends of the positioning baffle 32.

[0027] During the installation and use of the internal workpieces, the positioning baffle 32 can be clamped into the positioning vertical groove 31 first. This facilitates later installation and disassembly, and also provides positional support for the telescopic transmission assembly 4 and the sliding sealing assembly 5, thereby improving the positional stability of the structure.

[0028] The positioning baffle assembly 3 includes, but is not limited to, a fixed baffle structure, an adjustable baffle structure, and a guide baffle structure; in this embodiment, the positioning baffle assembly 3 preferably has a guide baffle structure.

[0029] The telescopic transmission assembly 4 includes a fixed plate 41. A reverse-threaded rod 42 is provided between the inner walls of the side ends of the fixed plate 41. A threaded slider 43 is threadedly connected to the inner wall of the reverse-threaded rod 42. A rotating frame 44 is installed on the side ends of the threaded slider 43 and the sliding sealing assembly 5. A first connecting bracket 45 and a second connecting bracket 46 are rotatably connected to the side ends of the rotating frame 44 for the rotatable connection between the threaded slider 43 and the sliding sealing assembly 5.

[0030] When the sliding sealing components 5 at both ends are positionally slidably sealed, the middle reverse threaded rod 42 can be rotated first. Under the inner wall thread drive, the threaded slider 43 on the inner wall will be moved in a concentrated position. Then, under the rotational connection of the first connecting bracket 45 and the second connecting bracket 46 at both ends, the sliding sealing component 5 at the side end will be slid stably to improve the uniform force during sliding and slide to the accurate position.

[0031] The telescopic transmission component 4 includes, but is not limited to, a screw transmission structure and a gear and rack transmission; in this embodiment, the telescopic transmission component 4 is preferably a screw transmission structure.

[0032] The sliding sealing assembly 5 includes a slope groove 51 and a sliding sealing frame 52. The slope groove 51 is formed on the inner walls of both ends of the groove structure 1 for sliding sealing of the sliding sealing frame 52. Limiting rods 53 are provided at both ends of the sliding sealing frame 52 for positioning and sliding.

[0033] When sealing the position of the wire trough structure 1, the sliding sealing frames 52 at both ends will slide under the transmission of the telescopic transmission component 4. During the position sliding, the limiting rods 53 at both ends of the sliding sealing frame 52 will slide along the position of the slope groove 51. At this time, the slope groove 51 is designed to be inclined. Under the sliding of the limiting rods 53 and the inclined design of the slope groove 51, the spacing between the wire troughs will be continuously adjusted, and the two ends of the wire trough structure 1 will be pressed together, thereby improving the structural sealing effect of the wire trough structure 1.

A sealing pressure plate 62 is installed on the inner wall of the bottom of the elastic reset member 61 for elastic sealing of the sliding sealing assembly 5.

[0036] When the sliding sealing assembly 5 slides in position, the sealing pressure plates 62 at both ends of the bottom, under the elastic support of the elastic reset member 61, will assist in pressing and sealing the gaps at both ends of the groove structure 1, so as to further reduce the generation of gaps and form a secondary sealing effect.

[0037] The elastic sealing component 6 includes, but is not limited to, a silicone rubber elastic element and a spring sealing gasket structure; in this embodiment, the elastic sealing component 6 preferably has a spring sealing gasket structure.

[0038] The working principle of the dustproof and waterproof sealed busbar trunking provided by this utility model is as follows:

[0039] In daily use, the internal cable trough structure 1 is first installed in its position. Then, the middle positioning baffle assembly 3 is positioned and installed on the inner wall of the cable trough structure 1. The telescopic transmission assemblies 4 and sliding sealing assemblies 5 at both ends are then installed and fixed in position. When sealing the entire cable trough structure 1, the middle telescopic transmission assembly 4 can be rotated first. Subsequently, the sliding sealing assemblies 5 at both ends will adjust their sealing position along the groove on the inner wall of the cable trough structure 1 and maintain a tight state to reduce rainwater from entering the inside of the cable trough from both ends. When the sliding sealing assembly 5 slides in position, the elastic sealing assembly 6 at the bottom will provide elastic support to further reduce the gaps between the cable troughs and form a secondary sealing treatment.

[0040] Compared with related technologies, the dustproof and waterproof sealed busbar trunking provided by this utility model has the following advantages:

[0041] Beneficial effects:

[0042] To improve the sealing effect of the cable trough during daily use, the telescopic transmission component 4 and the sliding sealing component 5 work together. During the rotation and tightening of the telescopic transmission component 4, the sliding sealing components 5 at both ends automatically adjust their sealing position and tightness according to the actual gap size at both ends. Even if the distance between the cable trough ends changes due to thermal expansion and contraction or installation errors, a tight fit is always maintained, and the force is evenly distributed during tightening, preventing localized leaks. Simultaneously, as the sliding sealing components 5 slide, the elastic sealing component 6 at the bottom deforms, filling any tiny gaps between the sliding sealing components 5 and the bottom of the cable trough, forming a secondary seal and further improving the overall waterproof and dustproof performance of the cable trough.
