[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Refer to Figure 1-7 , a ventilable base for a ring network box, including a ground foundation 4 and a base for carrying the ring network box. The base is fixedly arranged on the ground foundation 4. Ventilation grilles 1 are arranged around the base. Screw holes 2 are opened on the top surface of the base. The ring network box is fixedly arranged on the base. Baffles 13 for front and rear limiting of the ring network box are detachably arranged at the front and rear ends of the base. Two groups of resistance mechanisms for left and right limiting of the ring network box are arranged on the base.

[0029] In a specific embodiment of the present utility model, the ground foundation 4 provides an installation position and supports the base. The ground foundation 4 can be a concrete platform made on the ground; the base is used to support the ring network box, which can increase the distance between the ring network box and the ground foundation 4. By arranging the ventilation grilles 1 on the base, the ventilation at the bottom of the ring network box can be improved, the risk of moisture absorption can be reduced, and it is helpful for heat dissipation at the bottom of the ring network box and reduces the formation of condensation; through the arranged baffles 13, the front and rear positions of the ring network box can be limited, and through the arranged resistance mechanisms, the left and right positions of the ring network box can be limited, thereby improving the stability between the base and the ring network box.

[0030] The base is composed of several frame modules 3, and adjacent frame modules 3 are connected by a connecting plate 5 and a first bolt 6;

[0031] The frame module 3 consists of a channel steel frame and connecting columns. The channel steel frame is a rectangular frame welded by channel steels. One frame module 3 contains two channel steel frames, and the four corners of the two channel steel frames are fixedly connected through four connecting columns. The connection method can be welding. The ventilation grille 1 is fixedly arranged between the two channel steel frames, and threaded holes are provided on the connecting columns. Corresponding screw holes 2 are provided on the upper channel steel frame, and straight slots 15 are provided on the lower channel steel frame. For the specific structure, refer to Figure 3 ;

[0032] When adjacent frame modules 3 are connected, the adjacent ends of the two frame modules 3 are fitted together. Two through holes are provided on the connecting plate 5. The connecting plate 5 is placed at the connection of the two frame modules 3. The two through holes respectively correspond to the threaded holes of the two adjacent connecting columns on the two frame modules 3. Then, two first bolts 6 are respectively passed through the two through holes and screwed into the corresponding threaded holes to complete the connection of the two adjacent frame modules 3.

[0033] The screw holes 2 are provided on the top surface of the frame module 3. Straight slots 15 are provided at the bottom of the frame module 3. Ventilation grilles 1 are provided on all four sides of the frame module 3;

[0034] Bolts are pre-embedded in the ground foundation 4 during construction. When installing the frame module 3, the straight slots 15 on the frame module 3 are sleeved on the pre-embedded bolts, and then nuts are screwed on to fix the frame module 3 so that it is fixedly arranged on the ground foundation 4.

[0035] Several drainage grooves 14 are provided on the upper surface of the ground foundation 4. The bottom surface of the drainage grooves 14 is high in the middle and low at both ends. Through the provided drainage grooves 14, drainage can be used. Since ventilation grilles 1 are provided on the base, it is inevitable that rainwater may enter the base. In order to prevent water accumulation in the base, the drainage grooves 14 are provided for drainage.

[0036] Grooves 7 are provided on the front and rear end faces of the frame module 3. A convex block 16 is fixedly provided at the lower part of the baffle 13. The convex block 16 is clamped into the groove 7. The baffle 13 and the frame module 3 are detachably connected through a third bolt 12;

[0037] The grooves 7 on the frame module 3 are located on the front and rear surfaces of the upper channel steel frame. The grooves 7 are matched with the convex block 16. Through holes are provided at the lower part of the baffle 13, and threaded holes are provided at the positions of the grooves 7 on the upper channel steel frame. When installing the baffle 13, the convex block 16 on the baffle 13 is clamped into the groove 7, and then the third bolt 12 is passed through the through hole on the baffle 13 and screwed into the threaded hole at the position of the groove 7 to fix the position of the baffle 13. At the same time, due to the provision of the groove 7 and the convex block 16, the baffle 13 will not rotate around the third bolt 12. Baffles 13 are provided on the front and rear surfaces of the frame module 3.

[0038] The resistance mechanism includes a fixing plate 10, a screw rod 8 and a top block 11. The screw rod 8 is threadedly connected to the upper part of the fixing plate 10, and the top block 11 is rotatably arranged at the end of the screw rod 8. Two sets of resistance mechanisms are symmetrically arranged.

[0039] The fixing plate 10 is detachably connected to the top of the frame module 3 through a second bolt 9.

[0040] The fixing plate 10 is L-shaped. The bottom of the fixing plate 10 is on the frame module 3, and it is fixedly installed at a certain position on the frame module 3 by using two second bolts 9. The preferred position is the position close to the screw hole 2 on the side of the ring network box. When installing the resistance mechanism, first, after the ring network box is already on the frame module 3, select a suitable screw hole 2, and use the second bolt 9 to screw into this screw hole 2 to fix the fixing plate 10. After fixing, turn the screw rod 8 so that the top block 11 approaches and abuts against the side of the ring network box. Two sets of resistance mechanisms are respectively located on both sides of the ring network box, and the top blocks 11 respectively abut against both sides of the ring network box, so as to achieve the effect of limiting the left and right positions of the ring network box.

[0041] During installation, first, according to the size specifications and quantity of the ring network box, select the quantity of the frame module 3 (in this embodiment, three frame modules 3 are adopted). The width of the frame module 3 is the width of the ring network box, and make the ground foundation 4 according to the actual size. When making the ground foundation 4, it is necessary to embed bolts according to the straight slot 15 on the frame module 3 and pull out the drainage groove 14. After the ground foundation 4 is made, place the frame modules 3 one by one on the ground foundation 4, and make the corresponding straight slot 15 sleeved on the corresponding embedded bolts. Then connect the adjacent frame modules 3 together through the connecting plate 5 and the first bolt 6, and then screw the nuts on the embedded bolts to fix all the frame modules 3 to complete the installation of the base. Then place the ring network box on the base. If the bottom surface of the ring network box has the condition of being able to open holes, after opening the holes, use bolts to pass through the holes and then screw into the corresponding screw holes 2 on the frame module 3 to fix the position of the ring network box. In this case, the baffle 13 and the resistance mechanism may not be installed. If the bottom surface of the ring network box only has the condition of opening a small number of holes, after opening the holes, use bolts to pass through the holes and then screw into the corresponding screw holes 2 on the frame module 3 to fix the position of the ring network box, and then install the baffle 13 and the resistance mechanism to further limit the position of the ring network box.
