detailed description

Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

As a specific embodiment of the rack of the present invention, as shown in FIGS. 1 to 3 , the rack includes a fixed plate 1 , a rack body 2 and a base 3 sequentially connected from top to bottom. The fixed plate 1 is a U-shaped plate whose length is along the left and right directions, and the front and rear sides of the U-shaped plate are respectively provided with an outer flange structure for being fixed on the cabin roof. The frame body 2 includes more than two vertical stands 21 arranged side by side. An installation compartment for installing secondary equipment is formed between two adjacent vertical supports 21 . The front side of the installation compartment is an inlet. An open notch 20 is provided at a corner of the bottom front side of the stand 21 , and the notches 20 of all the stands 21 in the same row form a through cable routing channel for cables to pass through. The stand 21 includes a vertical plate on the front side. The vertical plate is provided with two rows of modular holes 211. The modular holes 211 in the left column are used to fix the secondary equipment on the left side of the vertical frame 21. The modular holes in the right row 211 is used to fix the secondary equipment located on the right side of the stand 21 . The base 3 includes a bracket 31 , a fixed sealing plate 32 and a movable sealing plate 33 located on the bracket 31 , and the movable sealing plate 33 adopts a stacked push-pull structure. The bracket 31 is located below the stand 21 and corresponds to the stand 21 one by one. When the movable sealing plate 3 is opened, the inner space of the base 3 communicates with the cable routing channel and the installation compartment, which is convenient for cables to enter and exit the rack. The base 3 allows cables outside the rack to enter the inside of the rack, and its inner space is also used as a storage space for redundant cables. In this embodiment, the stand 21 also includes an upper connecting plate at the top and a lower connecting plate at the bottom, and the upper connecting plate and the lower connecting plate are provided with fixing holes, and the upper connecting plate is fixedly connected with the bottom of the fixing plate 1 by bolts, The lower connecting plate is fixedly connected with the base 3 by screws. The stand 21 is provided with a plurality of cooling holes. The rack is used in the front wiring mode of the double column arrangement mode of the prefabricated cabin.

When in use, fix the fixing plates and the base on the upper and lower sides of the frame body to the cabin roof and the tank bottom respectively, and then fix a plurality of vertical frames between the fixing plates and the base respectively to complete the installation of the frame, which is convenient for installation and disassembly. The secondary equipment can be installed in the corresponding position of the installation compartment according to the needs, and the installation height can be adjusted through the modular holes on the left and right sides of the stand, which can make full use of the space in the cabin and improve the space utilization rate.

The frame structure of the present invention is based on an integrated design, so that the frame and the cabin are directly fixed and installed, and the structure is simple, which avoids the heavy operation problem of the overall entry of the screen cabinet in the existing secondary equipment prefabricated cabin and the specifications of the screen cabinets from different manufacturers. The problem of inconsistent size and fixed structure avoids the waste of resources caused by repeated protection of traditional cabinets and cabins, and reduces costs. The gaps of the vertical racks in the same row form an open cable routing channel for cable routing, which is convenient for personnel to carry out cable installation in the early stage and equipment modification and expansion in the later stage, reduces debugging time, and improves wiring efficiency. The usable space of the installation compartment is large, and the equipment can be installed at the corresponding height according to the needs, which improves the space utilization rate.
