Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.
In the prior art, a transverse expansion method is adopted to expand the capacity of the optical cable distribution box, and the specific construction steps are as follows: firstly, dismantling the optical cable floor type cross connecting cabinet comprises the working quantities of field cleaning of the service condition of the existing optical cross connecting cabinet, formulation of a cabinet dismantling scheme (ensuring no fault to the service in use), field dismantling and the like; secondly, installing a floor type cross connecting box base and carrying out workload of measuring field topography, dismantling, expanding, reconstructing and the like on the original base according to the size of the new box body; and thirdly, the optical cable floor-type distribution box is installed, the expansion box body is customized according to the actual field terrain measurement, and the optical cable floor-type distribution box is transported to the field to carry out the work load of module decomposition, installation, box body assembly, grounding construction and the like. Resulting in a large workload; the expansion is easily influenced by the peripheral space of the box body, and the batch production is not convenient; when the box body is disassembled, the workload is large, and the stability of the original optical path is easily influenced in the operation process; the operation difficulty is high, and the stability of an original light path needs to be ensured while the original box body shell is dismantled; noise and dust are serious in the construction process, and garbage generated after construction is more, so that the construction method is not beneficial to environmental protection. In view of the above reasons, the present application adopts a longitudinal expansion mode to expand the capacity of the optical cable cross connecting cabinet, and the specific design is as follows:
as shown in fig. 1 to 5, a large capacity optical cable cross-connecting box without longitudinal capacity expansion and disassembly includes a box body 1, a base 2, a capacity expansion box 3 and a box cover 4, wherein the upper end of the base 2 is fixed with the box body 1, the top end of the box body 1 is detachably connected with the capacity expansion box 3, the top end of the capacity expansion box 3 is detachably connected with the box cover 4, the top of the box body 1 and the top of the capacity expansion box 3 are both provided with a connecting groove 5, the bottom of the box cover 4 and the bottom of the capacity expansion box 3 are both fixed with a connecting piece 6, the connecting piece 6 on the capacity expansion box 3 is matched with the connecting groove 5 on the box body 1, and the connecting groove 5 on the;
The working principle of the adapting of the connecting groove 5 and the connecting piece 6 is as follows: when the electromagnet 9 is not electrified, the connecting piece 6 is arranged in the connecting groove 5, and the iron core 8 on the connecting piece 6 is attracted with the magnet 7 in the connecting groove 5 to achieve the connecting effect; when the electromagnet 9 is electrified, the magnetic pole of the electromagnet 9 can be changed by changing the current direction of the electromagnet 9, so that the electromagnet 9 and the magnet 7 repel each other, and the aim of convenient disassembly is fulfilled.
Can establish spread groove 5 and connecting piece 6 into four during concrete implementation, four spread grooves 5 and four connecting pieces 6 all are the rectangle and arrange, and flash tank 3 is a plurality of, and a plurality of flash tanks 3 all are on box 1 through connecting piece 6 and the fore-and-aft connection of the adaptation of spread groove 5. The stability of the connection is increased.
The specific implementation process for expanding the capacity of the optical cable cross connecting cabinet comprises the following steps: when needs carry out the dilatation to the optical cable distributing box, through the mutual repulsion of electro-magnet 9 and magnet 7, pull down case lid 4 from the top of box 1, then install flash tank 3 on box 1 through the cooperation of connecting piece 6 with spread groove 5, then install case lid 4 on flash tank 3, realize the dilatation installation. Whole dilatation installation, the installation is simple swift, reduces the work load of dilatation construction, can not produce noise and dust pollution, effectively reduces the production of rubbish, improves work efficiency, obviously reduces the construction degree of difficulty, has improved production efficiency. When practical application, but flash tank 3 batch production, when the dilatation once more, only need pull down case lid 4, carry out the dilatation once more on flash tank 3, need not to measure the dimensional data of the box that needs the dilatation, only need can directly produce the accessory according to the design drawing and the dilatation port quantity of box, obviously reduce the dilatation earlier stage work load, improve production efficiency. Meanwhile, the increase of time cost caused by the fact that specially-made parts and a volume-expanding box body are removed when the volume expansion is needed is avoided.
The current optical cable distributing box inner structure is complicated, each region does not have clear and definite division, lead to wiring circuit mixed and disorderly, space utilization is low, the internal capacity is low, the optical cable crisscross each other leads to overhauing more difficult, easily cause the damage to other optical cable during the maintenance simultaneously, the degree of difficulty of overhauing is improved, and adopt vertical dilatation back, the internal circuit of optical cable distributing box more adds, if carry out reasonable division to inside circuit, lower space utilization, will reduce the installation volume of dilatation case 3, the dilatation of optical cable distributing box has been reduced to a great extent.
