Description

Technical Field

[0001] The utility model relates to the field of tubular busbar bridges, and more specifically to a tubular busbar bridge with a multi-channel layer interconnection structure. Background Art

[0002] The tubular busbar is a busbar product that uses copper tubes or aluminum alloy tubes as conductors and is insulated externally. Its cross-section is usually circular.

[0003] When installing tubular busbars, it is usually necessary to use a busbar bridge to improve the stability of the structure. In the actual installation process, the inventor found that when installing multiple tubular busbars, they need to be placed one by one inside the corresponding clamps before they can be fixed. It is not convenient to place all the multiple tubular busbars on the bracket at one time for preliminary positioning and then fix them separately. There is a lack of corresponding redundant structure at the contact part between the clamps and the tubular busbars, which is not conducive to the deformation and expansion of the tubular busbar under temperature changes. Therefore, we proposed a tubular busbar bridge with a multi-channel layer interconnection structure to solve the above problems. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention specification; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1-Figure 4A tubular busbar bridge with a multi-channel layer interconnection structure includes a circular protective ring 1, an opening 101 is opened on the top of the circular protective ring 1, and a group of outward extension parts 102 are arranged on the top of the circular protective ring 1 located at the opening 101, a mounting crossbeam 103 is fixedly welded at the bottom of the circular protective ring 1, a plurality of lower supporting members 2 with the same structure are symmetrically fixedly welded on the inner wall of the circular protective ring 1, and upper clamping members 3 are fixedly installed on the top of the plurality of lower supporting members 2 by bolts, a tubular busbar body 4 is clamped between the lower supporting members 2 and the upper clamping member 3, an open through groove 104 is opened on the top of a group of outward extension parts 102, a group of ear seats 105 are fixedly welded on the top side wall of one of the outward extension parts 102, and a pull rod 6 is rotatably connected between the ear seats 105 by rivets, an external thread structure is opened at the end of the pull rod 6, and the end of the pull rod 6 is connected to another open through groove 104 by a locking nut 5.

[0027] The operating principle of this tubular busbar bridge with a multi-channel layer interconnection structure is:

[0028] First, install the bottom of the circular protective ring 1 through the installation beam 103, and then place a number of tubular busbar bodies 4 equal to the number of the lower supporting parts 2 in the circular protective ring 1 through a group of outward extension parts 102 and openings 101. Then the staff can place the tubular busbar bodies 4 in the corresponding lower supporting parts 2 respectively, and lock them through the upper clamps 3 and bolts. Finally, rotate one end of the pull rod 6 to the inside of another corresponding open through groove 104, and gradually lock it through the locking nut 5, so that there is tension between a group of outward extension parts 102 to prevent deformation in the later stage.

[0029] Embodiment 2:

[0030] In view of the above embodiment 1, for further description, refer to Figure 3 and Figure 4 A group of pasting grooves 201 are provided on the inner walls of the lower support 2 and the upper clamp 3, and a rubber ring 7 is fixedly pasted inside the pasting grooves 201. A support ring 8 is provided on the outer wall of the rubber ring 7, and a clamping edge 801 with a T-shaped cross-section is fixedly connected to the support ring 8. A clamping groove that is compatible with the outer structure of the clamping edge 801 is provided inside the rubber ring 7. The support ring 8 is clamped on the outer wall of the rubber ring 7 through the clamping edge 801 and the clamping groove. The inner wall diameters of the support ring 8 on the lower support 2 and the upper clamp 3 are equal, and the inner wall diameter of the support ring 8 is smaller than the inner wall diameter of the arc-shaped portion on the lower support 2 and the upper clamp 3. The support ring 8 is a semicircular structure integrally cut and formed by metal material, and the rubber ring 7 is a semicircular structure integrally injection molded by rubber material.

[0031] Under the condition of temperature change, the tubular busbar body 4 will undergo a certain expansion and contraction deformation. At this time, since the rubber ring 7 is made of rubber material and has a certain elasticity, the support ring 8 is connected to the upper clamp 3 or the lower support 2 through the corresponding rubber ring 7. Therefore, in the process where the tubular busbar body 4 deforms and drives the support ring 8 to move, the rubber ring 7 provides a certain redundant avoidance space, thereby achieving the effect of protecting the connection of the tubular busbar body 4.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
