Description

Technical Field

[0001] The utility model relates to the technical field of ring network cabinets, in particular to a ring network cabinet with high safety. Background Art

[0002] Ring main unit is a group of electrical transmission and distribution equipment (high-voltage switchgear) installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core part adopts load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, factories and enterprises.

[0003] At present, when using existing ring network cabinets, multiple ring network cabinets are generally placed side by side on the top of the steel frame to prevent the influence of ground moisture on the ring network cabinet. During the installation process, due to the large size of the ring network cabinet, it is often necessary for multiple installers to carry and assemble it. Lifting the cabinet by multiple people not only consumes a lot of manpower, but also requires multiple people to work together when carrying the cabinet. Once the cabinet is unevenly stressed, the cabinet is prone to imbalance or even tipping over, which poses a certain hidden danger to the personal safety of the installers. Therefore, we propose a highly safe ring network cabinet. Utility Model Content

[0024] See also Figure 1-4The utility model provides a ring network cabinet with high safety, including a base 1, a left bracket 2 and a right bracket 3 are fixedly connected to the top of the base 1 on both sides, a cover plate 8 is arranged on the side away from each other of the left bracket 2 and the right bracket 3, and the circumference of the cover plate 8 is fixed to the left bracket 2 and the right bracket 3 by bolts, so as to facilitate the disassembly and assembly of the cover plate 8 and the protection and maintenance of the internal equipment of the left bracket 2 and the right bracket 3.

[0025] In this embodiment, anti-skid rubber pads are fixedly connected to the tops of the left bracket 2 and the right bracket 3, and the two sides of the ring network cabinet 7 are respectively placed on the tops of the left bracket 2 and the right bracket 3, so as to achieve an anti-skid effect and improve the positioning stability of the ring network cabinet 7.

[0026] A ring network cabinet 7 is commonly provided on the top of the left bracket 2 and the right bracket 3. A motor 4 is embedded and fixedly connected inside one end of the left bracket 2. The driving shaft of the motor 4 passes through the left bracket 2 and is fixedly connected to a threaded rod 5. The outer wall of the threaded rod 5 is threadedly connected to a slide seat 6.

[0027] A rectangular groove 13 is provided inside the right bracket 3, and a guide rod 14 is fixedly connected between the two sides of the inner wall of the rectangular groove 13. The guide rod 14 passes through the slide 6 and is slidably connected thereto, thereby limiting the moving direction of the slide 6 and ensuring the operating stability of the slide 6.

[0028] A hydraulic rod 9 is fixedly connected at the center of the outer bottom of the slide 6, and an inspection groove 15 is fixedly connected at the center of the top of the base 1. The hydraulic rod 9 corresponds to the inspection groove 15 and the bottom of the hydraulic rod 9 is located in the inspection groove 15, which is convenient for the hydraulic rod 9 to be connected to the external oil pump to provide hydraulic pressure, and at the same time, it is convenient to provide sufficient space for the staff to repair and maintain.

[0029] The telescopic end of the hydraulic rod 9 passes through the slide 6 and is fixedly connected to the support frame 10. The top surface of the support frame 10 is the same size as the bottom surface of the ring network cabinet 7, and the top surface of the support frame 10 fits the ring network cabinet 7. When the support frame 10 is raised, it can just contact the bottom of the ring network cabinet 7 and support it, and can replace the staff to carry and shift the ring network cabinet 7.

[0030] The four corners on the top of the slide seat 6 are fixedly connected to the limit rods 11, and the support frame 10 is provided with limit holes 12 corresponding to the limit rods 11. The limit rods 11 and the limit holes 12 are plugged in correspondence, so as to ensure the support stability of the ring network cabinet 7 when the support frame 10 is lifted or lowered.

[0031] When in use, first connect the motor 4 to the external power supply, connect the hydraulic rod 9 to the external oil pump, and when installing the ring network cabinet 7, start the hydraulic rod 9 to drive the support frame 10 to rise vertically along the limit rod 11 inside the slide 6. At this time, the slide 6 is located at either end of the base 1, which is convenient for the staff to place the ring network cabinet 7 on the support frame 10.

[0032] Then, the motor 4 is started to drive the threaded rod 5 to rotate, and the slide 6 is driven to slide outside the guide rod 14, so that the slide 6 gradually moves to any desired installation position on the top of the base 1.

[0033] After it is in place, start the hydraulic rod 9 to lower the support frame 10, and the ring network cabinet 7 will drop accordingly until the two ends of the bottom of the ring network cabinet 7 are respectively located on the top of the left bracket 2 and the right bracket 3. The staff only needs to place it on the top of the support frame 10. During the installation on the base 1, there is no need for multiple staff to carry it together, which improves the safety of the placement and displacement of the ring network cabinet 7. The device can realize the rapid placement of the cabinet, saving a lot of time and manpower, and improving the efficiency of disassembly and assembly of the cabinet.

[0034] On the contrary, when the cabinet needs to be dismantled or moved, the motor 4 is started first to drive the slide 6 to move to the bottom of the ring network cabinet 7, and then the hydraulic rod 9 is started to drive the support frame 10 to rise, gradually contact the bottom of the ring network cabinet 7 and lift it up, and then the motor 4 and the threaded rod 5 are used again to drive the ring network cabinet 7 to move. When it moves to the end of the base 1, the ring network cabinet 7 can be conveniently and directly removed.

[0035] The coordinated work between the motor 4 and the hydraulic rod 9 in the present device can be realized by external PLC programming to realize on-site remote control operation, which is a prior art and will not be described in detail here.

[0036] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
