Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch equipment, in particular to a ring network cabinet. Background Art

[0002] When the ring main unit is expanded and connected, it is usually pushed by manpower, which requires a lot of manpower, is inefficient and cannot be installed properly. If there are multiple units of ring main units or the foundation is uneven and rough, the difficulty is particularly prominent. Only simple tools such as crowbars and logs can be used to slowly move the ring main unit, which may cause uneven quality of the connected cabinets; and if the two switch cabinets are not tightened enough, there will be gaps between the busbars, which will bring safety hazards.

[0003] Through searching, it is found that the prior art with announcement number CN106451118B also utilizes a cabinet combining device to complete the joining of two cabinets together. However, after the cabinets are joined, bolts still need to be passed through the two cabinets and connected with nuts to complete the mutual fixation of the two cabinets after joining. Since one end of the bolt passes through the cabinet and is connected with the nut, two wrenches are required during the assembly process, one for causing the bolt to rotate and the other for preventing the nut from rotating. Therefore, sufficient space needs to be reserved for the two cabinets during the joining process, otherwise it is difficult to join the two cabinets, and the above method also reduces the efficiency of joining the cabinets. In particular, after the two cabinets are joined together, it cannot be guaranteed that the position of each circular hole for the bolt to be inserted is completely corresponding, so local fine-tuning is still required. Since the two cabinets are closely joined, it is difficult to complete the fine-tuning of the position between the cabinets. Utility Model Content

DETAILED DESCRIPTION

[0016] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0017] See also Figure 1-3 The utility model provides an embodiment: a ring main unit, comprising a first cabinet 1 and a second cabinet 2; mounting holes 4 are provided on the facing surfaces of the first cabinet 1 and the second cabinet 2; and a cabinet combining member 3 is inserted into the mounting holes 4 of the first cabinet 1 and the second cabinet 2, so that the facing surfaces of the first cabinet 1 and the second cabinet 2 are closely fitted;

[0018] Specifically, the cabinet combining member 3 includes a first clamping member 30 and a second clamping member 32 of the same structure, and a driving member 31 is further provided between the first clamping member 30 and the second clamping member 32; a support rod 310 is provided on both the first clamping member 30 and the second clamping member 32, and the driving member 31 is rotated on the support rod 310 to make the first clamping member 30 and the second clamping member 32 move in opposite directions.

[0019] In summary, after the first cabinet 1 and the second cabinet 2 are fitted together, the cabinet merging member 3 is inserted into the mounting hole 4, that is, the first clamping member 30 is clamped above the mounting hole 4, and the second clamping member 32 is clamped below the mounting hole 4. At this time, the two clamping members can be used to preliminarily position the two adjacent cabinets; then the driving member 31 is rotated to cause the two clamping members to move back to back, so that the mounting holes 4 between the two cabinets can be aligned to achieve fine-tuning of the cabinet positions. In particular, the device has a simple structure and can also act as a fastener installed in the mounting hole 4 to achieve long-term maintenance of the positions of the two cabinets. Therefore, while achieving the alignment of the two cabinets, bolts and nuts are not required to solve the problems existing in the prior art.

[0020] Furthermore, since the first clamping member 30 and the second clamping member 32 are provided with a slide groove 38 on the facing surfaces, and the support rod 310 is slidably connected to the slide groove 38 through the provided pad 39, the sliding pad 39 facilitates the smooth docking of the driving member 31 and the support rod 310, and also facilitates the movement of the driving member 31 to the center position of the mounting hole 4, so that when the two clamping members move away from each other, the two clamping members will not fall off due to uneven force, thereby further ensuring the position alignment of the mounting hole 4.

[0021] On the basis of the above solution, since the first clamping member 30 also includes a supporting plate 311; one end of the supporting plate 311 is connected to the hook body 33, and the other end of the supporting plate 311 is connected to the supporting plate 35; therefore, the first clamping member 30 and the second clamping member 32 can be in surface contact with the mounting hole 4, so as to further ensure the stability of the two clamping members when in use. The hook body 33 and the supporting plate 35 are vertically mounted on the supporting plate 311.

[0022] Furthermore, since the support plate 35 is threadedly matched with the push rod 36 through the internal threaded hole 37, the two cabinets can be further fitted together by tightening the push rod 36. In summary, the drive member 31 can achieve the upper and lower alignment of the two cabinet positions, and the push rod 36 can further fit the two cabinet positions, thereby further improving the fine-tuning ability of the equipment.

[0023] In addition, during actual use, the hook body 33 of the first clamping member 30 is hooked on the first cabinet 1, and the support plate 35 is located inside the second cabinet 2; the hook body 33 of the second clamping member 32 is hooked in the second cabinet 2, and the support plate 35 is located in the first cabinet 1. This staggered arrangement makes the fit between the two cabinets tighter, and the push rod 36 does not require a nut during the tightening process.

[0024] Furthermore, since one end of the push rod 36 passes through the internal threaded hole 37 and is movably connected to the provided gasket 34, the gasket 34 can be used to expand the contact area between the push rod 36 and the cabinet, thereby avoiding the phenomenon that the push rod 36 causes deformation of the cabinet during the tightening process.

[0025] Furthermore, since the support rod 310 and the driving member 31 are threadedly matched, the first clamping member 30 and the second clamping member 32 can be moved away from each other by tightening the driving member 31. Conversely, the first clamping member 30 and the second clamping member 32 can be moved toward each other by rotating the driving member 31, so that the pad 39 can be smoothly installed in the slide groove 38. In addition, since the driving member 31 has a polygonal columnar shape, it is convenient for the user to use a wrench to rotate the driving member 31.

[0026] In summary, the device provides a cabinet combining component 3 that can be installed inside the ring network, and then utilizes the simple structure of the cabinet combining component 3 to achieve fine-tuning of the positions of two adjacent cabinets after they are fitted together, and the positions can be permanently maintained after fine-tuning, so that the two cabinets do not need to be fixed with bolts after being combined, which not only improves the cabinet combining efficiency, but also reduces the use of bolts and nuts.

[0027] In addition, in order to further ensure the alignment of the positions of the cabinets, a long strip-shaped through hole (not shown in the figure) can also be set below the mounting hole 4, wherein the central axis of the through hole is perpendicular to the central axis of the mounting hole 4. Therefore, when the cabinet merging component 3 is connected to the mounting hole 4, another cabinet merging component 3 is used to connect to the through hole, so that the upper and lower positions of the two cabinets can be aligned, and the front and rear positions of the cabinets can be aligned.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
