Detailed Implementation

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0017] A highly reliable primary and secondary integrated ring network box, such as Figure 1 and Figure 2 As shown, the device includes a housing 1, inside which are distributed several main equipment units. Each main equipment unit includes a ventilation base 2 and individual equipment units 3 on the ventilation base 2. The ventilation base 2 is equipped with casters (the outer side of the individual equipment units 3 is fixed with handles 31 for easy pulling out or pushing into the housing 1). The housing 1 includes two air duct outlets 4 at the top, which can be equipped with partitions in the middle to achieve ventilation while also allowing the ring network box (individual equipment units 3) to be easily moved in and out of the outer housing 1 via the casters, facilitating installation and subsequent maintenance. The air outlet 4 includes an air guide fan 41 and a filter 42. The air guide fan 41 guides the air to leave from the air outlet 4, realizing active ventilation and reducing the accumulation of internal heat. Specifically, air outlets 4 are respectively set at both ends of the top of the box 1. Inclined water guide plates 12 are fixed at both ends of the box 1. The water guide plates 12 are inclined downwards on the outside. The two are distributed in a figure-eight shape. The air outlet 4 is located on the upper side of the water guide plate 12 and a downwardly set water guide eaves 43 are fixed on the outer side of the top. The air outlet 4 includes an opening on the water guide plate 12, a horizontal top plate covering the upper side of the opening, and connecting side plates between the two sides of the horizontal top plate and the water guide plate 12. The water guide eaves 43 are integrally connected to the lower outer end of the horizontal top plate. A parallel baffle structure is fixed below the water guide plate 12. The inner end of the baffle structure extends inward and connects to the mounting cylinder. The air guide fan 41 and filter screen 42 are fixed inside the mounting cylinder. The mounting position of the mounting cylinder is moved back by the baffle structure, thereby moving away from the opening on the water guide plate 12 and improving waterproofing. Several drainage micro-holes can be opened on the outer side of the box 1 above the baffle structure.

[0018] like Figure 1 and Figure 2 As shown, the ventilation base 2 includes an air inlet 21 on the outside and an air outlet 22 on the top. The box body 1 is also provided with a door 11 for opening and closing. The door 11 abuts against the top of the upper side or the outer side of the ventilation base 2 (in this embodiment, the door 11 abuts against the upper side of the ventilation base 2). Specifically, the ventilation base 2 includes a base 23 and a ventilation plate 24. L-shaped positioning blocks 232 are fixedly connected to the four corners of the base 23. The device unit 3 is confined within the positioning blocks 232. Casters (universal casters or other wheels) are fixedly installed below the base 23. The device unit 3 is placed on the base 23. Several air inlets 21 are opened on the outer side of the ventilation plate 24. Several mounting blocks 241 are fixed to the inner side of the ventilation plate 24. The inner side of the mounting blocks 241 is connected to the base 23 by screws, thus ensuring the ventilation plate... There is a gap between the ventilation plate 24 and the base 23, forming an air outlet 22 that runs vertically through the base 23. (In this embodiment, the ventilation plate 24 is U-shaped and is connected to the base 23 on the outside and both sides by mounting blocks 241 to form an air outlet 22. The outer part of the ventilation plate 24 serves as a cover, and the door 11 abuts against its upper side. The lower end of the ventilation plate 24 abuts against the bottom plate of the box 1 through a number of hinged plates, fixed flexible baffles, or dense brushes. It can also be provided with a baffle structure.) To facilitate guiding movement, several guide rails 51 are installed inside the housing 1, and several guide wheels 231 are connected to the outside of the base 23. The guide wheels 231 abut against the corresponding guide rails 51 (the ventilation plate 24 is set to avoid the guide rails 51 on both sides to prevent interference; for example, the guide rails 51 are on the bottom, while only the upper half of the ventilation plate 24 is retained on both sides, and the lower half is cut off to allow the guide rails 51 and guide wheels 231 to guide each other). The guide rails 51 can also be set at the bottom and adapted to the moving wheels under the ventilation base 2.

[0019] like Figure 3 As shown, several mounting plates 5 are connected inside the housing 1 (the mounting plates 5 can be integrally connected to the bottom plate of the housing 1, or they can be connected to the bottom plate by screws for easy disassembly and replacement; in this embodiment, the housing 1 is installed on the sunken surface to facilitate the movement of the main body of the equipment into it, and it can also be connected to the outside of the bottom plate of the housing 1 by means of ramps or other means for easy movement). Guide rails 51 are fixedly connected to both sides of the mounting plates 5. A baffle 52 is detachably connected to the mounting plates 5. The baffle 52 has the same shape and size as the outer side of the ventilation base 2. There are at least two positions on the mounting plates 5 for the baffle 52 to be installed. One position is located on the inner side for the ventilation base 2 to enter from the outside, and the other position is located on the outer side and replaces the ventilation base 2 for the equipment unit 3 to be directly placed in. In this embodiment, several insert rods are connected downward to the lower side of the baffle 52. The insert rods are inserted downward to the mounting plate 5 (corresponding insertion hole groups are opened on the inner and outer sides of the mounting plate 5 respectively). Two slots are opened at both ends of the inner side of the guide rail 51. The two ends of the baffle 52 are integrally connected to the insert blocks corresponding to the slots, so that the baffle 52 can be inserted downward more stably at the outer or inner position.

[0020] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
