Description
Technical field
The utility model relates to a kind of buried guard box that is used for buried fiber cable joint and buried battery pack protection.
Background technology
Present intercity optical cable laying will depend on electric power or communication corridor; To drop into substantial contribution on the one hand in newly-built corridor, and can take up room for a long time, cause huge waste; When depending on electric power or communication corridor; Because be not easy to continue between span, optical cable need be produced by the spacing of shaft tower, production has proposed extra requirement to optical cable.Therefore the scheme of communication cable provided underground is adopted in newly-built in the world fiber optic communications corridor more.Provided underground has multiple advantage:
Do not influence crop and building on the ground, do not take aboveground space.
Buried temperature stabilization, the optical fiber unaffected by temperature fluctuations.
Climate effect is little, does not have because of icing, accumulated snow or strong wind cause disconnected cable accident to take place.
Optical cable is safe and reliable, the hidden danger that no aerial optical cable is hung up by vehicle.
The defective of damage such as no gunslinging.
During provided underground, optical cable be embedded in underground 0.8 ~ 1.2 meter dark underground, optical cable producer can produce optical cable according to production and transport ability situation, no longer sticks to the shaft tower distance.In the construction, when every section optical cable laying arrives end, need carry out joint and handle.Get into guard box as the hole of advancing of leading in cable through guard box; Continue optical cable as the portal entering guard box of lead wire through guard box; Leading in cable with draw optical cable and in guard box, carry out fused fiber splice, and butt junction protects, extension continues to lay again.
Optical cable itself has good autoprotection measure, but when fiber cable joint, the protective seam of optical cable is peeled off, and inner protective layer removes, and carries out naked fine joint.A little less than naked fibre is highly brittle, in the absence of protection, excessive vibration, foreign matter collide with in addition insect or other toy all can cause irreversible destruction to optical fiber; Under the situation of humidity, the hydrogen in the water can enter into optical fiber, and hydrogen can destroy the tissue of optical fiber, finally causes the loss of signal of Optical Fiber Transmission to strengthen, even because of the too much decay of signal, influences the transmission range of signal.Therefore, when raining, irrigating and underground water is arranged, must fibre-optical splice be carried out security seal, avoid subterranean cable to be in the normal function of moist environmental impact product; After optical fiber is infected with dirt, can have influence on the optical fiber life-span, after optical fiber carries out joint, must carry out encapsulation process, guarantee that product environment of living in is clean.The seal protection problem of optical fiber need solve.
The base station is because play the function of important signal transmission; In the course of the work; There is power circuit that it is carried out power supply and supplies with, for guaranteeing to have a power failure or during power failure the communication signal normal transmission; Require the base station that standby power supply must be arranged, for being out of order or stable emergency power pack is provided during temporary interruption at conventional power supply in the base station.Power supply is several group storage batteries, starts working during conventional power cut-off, during conventional power supply energising, is in the charging stand-by state.Utilization builds on when setting up small building as the protective equipment of standby power supply on the ground, and when receiving agro-farming, the safety of facility can not be protected, and causes the safety of standby power supply not protect by the time.Be built in open-air base station power facility, because product is a low-voltage equipment, the stolen in the open air problem of unmanned, battery is difficult for solving.Need a kind of buried guard box to realize necessary requirement.
During the optical cable provided underground, agricultural, transportation ground construction etc. influence optical cable in order to avoid on the ground, need buried degree of depth generally between 0.8m to 1.2m.The pressure that requires underground joint protective case will bear several tons, guard box can not have cracking, infiltration or the stable distortion of optical cable occur influencing.
Base station reserve battery guard box has the characteristics of cable protection case except requiring product, also requires to have the inlet and outlet piping of turnover cable, and requirements for pipes is drawn ground, under different weather conditions, can not intake.The inlet and outlet piping mouth protects, and has avoided worm, mouse to get in the case, and evil influences battery and annex operate as normal, and requires the guard box requirement to have ventilation function, guarantees that the heat in battery operated can be discharged smoothly.
Guard box requires product each item function-stable in long-term buried process, do not allow to occur problems such as mouldy, that intensity is low.During normal operation, buried case performance is unaffected on ground for farm implements, agricultural transportation vehicle.
The utility model content
In order to solve the problems of the technologies described above, it is a kind of when the optical cable provided underground that the utility model embodiment provides, and can effectively carry out the buried guard box of seal protection to fiber cable joint and electric battery.Said technical scheme is following:
The utility model proposes a kind of buried guard box that is used for buried fiber cable joint and buried battery pack protection; Comprise casing and the case lid processed by fiberglass; Be provided with seal between said casing and the case lid, to seal said casing, said tank surface is provided with at least two through holes; Said through hole and cabinets cavity conducting; Said through hole is provided with sealed pipe fittings, so that cable seals said through hole when getting into said casing through through hole, is provided with support in the said casing with fixedly fibre storing disc, electric battery and wear fine pipe wrapping head.
Preferential as technique scheme is provided with reinforcement in said casing and the case lid.
Preferential as technique scheme, said support is fixed in the said casing through stationary installation
Preferential as technique scheme, said fibre storing disc is provided with the tempreature bulb deck, with the support optical fibers joint.
Preferential as technique scheme, casing and case lid are processed by fiberglass.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
When growing apart from the provided underground optical cable; The utility model can be protected fiber cable joint and base station standby power supply; Solved the problem of the underground joint protective of ground buried fiber optic cable, overcome the base station standby power supply simultaneously and can only be located at the disadvantage that the protection building is set up on ground separately.The utility model intensity is high, can resist the pressure of 300KN; And good seal performance, under 2 meters depth of water states, long-term ne-leakage; After the installation, Maintenance free, stable performance, long service life, safe and reliable.
