Description
Technical field
The underground box that the utility model relates in technical field of electric power becomes housing, and especially a kind of waterproof underground box becomes housing.
Background technology
In order to ensure the operation that the underground box elongated phase is safe and reliable, the waterproof that underground box becomes is key problem, the particularly sealing of the cable aperture most important thing especially.Existing underground box becomes and adopts traditional sealing system: prefabricated case becomes housing and leaves cable preformed hole, carries out wearing cable, shutoff in buried work progress.Sealing complex process, poor reliability.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides one to improve waterproof effect, ensures that the waterproof underground box of the elongated phase safe and reliable operation of underground box becomes housing.
The purpose of this utility model is realized by following technological means:
A kind of waterproof underground box becomes housing, comprise housing, lower housing portion makes cable aperture, it is characterized in that: in cable aperture, a seal frame is installed, a rectangular through-hole is made at the center of sealing framework, one deck or multi-layer sealed modular unit is put at the upper surface of rectangular through-hole base plate, every layer of seal modules unit is formed by one or more seal modules be arranged side by side, each seal modules is formed by lower bottom base and upper holder block, and the binding face of this lower bottom base and upper holder block is made for the circular hole through cable; Plug-in mounting sealing pressing gripping members between the superiors' seal modules unit and the upper plate of rectangular through-hole; Equal plug-in mounting interlayer board between adjacent two layers seal modules unit, between the superiors' seal modules unit and sealing pressing gripping members.
And when seal modules unit is multilayer, it is arranged above and below.
And, plug-in mounting cable or central plug in the circular hole between described lower bottom base and upper holder block.
And described seal frame is stainless steel material, it is cast in case and becomes on housing.
And described seal modules, sealing pressing gripping members and central plug are halogen-free fireproof rubber material.
And described interlayer board is stainless steel material.
And the water-repellent paint that described housing adopts water-proof concrete to add high reliability is built and is formed.
Advantage of the present utility model and good effect are:
1, the cable aperture selected module type sealing system of this housing seals, and model machine have passed the degree of protection test of national automatically controlled controller switching equipment Quality Supervision and Inspection Center.Conclusion is as follows: the requirement model machine according to national standard " GB4208-2008 " soaks 7 days, and surrounding is without water inlet, water stain, Seepage, and shell protection grade reaches the requirement of IPX8.
2, the cable aperture of this housing expands through mechanical compression, and the sealing of cable module just completes.This structure installment is simple, improves operating efficiency and operational reliability.
3, this housing adopts water-proof concrete to add the water-repellent paint of high reliability to build and form, and this housing has the feature of anticorrosion, antiseepage, waterproof, can improve the waterproof effect of equipment.
4, the second layer seal modules unit in this housing is reserved layer, and the cable increased after convenient can be installed easily, does not need perforate again.In addition, the circular hole aperture of upper and lower two-layer seal modules is usually different, so that the cable of plug-in mounting different-diameter.
5, the utility model is a kind of design science, the waterproof underground box of rational in infrastructure, easy to use, good sealing effect becomes housing, the cable aperture of this housing adopts mechanical compression Expansion sealing mode, its sealed waterproof effect is good and simple to operation, after using can extension device useful life, ensure the safe and reliable operation of underground box elongated phase.

Fig. 2 is the I portion partial enlarged drawing of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection range of the present utility model with this.
A kind of waterproof underground box becomes housing, and comprise housing 4, lower housing portion makes cable aperture 8, in cable aperture, install a seal frame 1.The water-repellent paint that housing adopts water-proof concrete to add high reliability is built and is formed.Seal frame is stainless steel material, and it is cast in case and becomes on housing.
A rectangular through-hole is made at the center of seal frame, puts one deck or multi-layer sealed modular unit at the upper surface of rectangular through-hole base plate, and when seal modules unit is multilayer, it is arranged above and below.The seal modules 2 that every layer of seal modules unit is arranged side by side by one or more is formed, each seal modules is formed by lower bottom base and upper holder block, the binding face of this lower bottom base and upper holder block is made for the circular hole (that is: all making half slot at the upper surface of lower bottom base and the bottom surface of upper holder block) through cable, plug-in mounting cable 7 or central plug 9 in this circular hole.The circular hole aperture of upper and lower two-layer seal modules is usually different, so that the cable of plug-in mounting different-diameter.
Plug-in mounting sealing pressing gripping members 3 between the superiors' seal modules unit and the upper plate of rectangular through-hole; Equal plug-in mounting interlayer board 5 between adjacent two layers seal modules unit, between the superiors' seal modules unit and sealing pressing gripping members.Seal modules, sealing pressing gripping members and central plug are halogen-free fireproof rubber material.Interlayer board is stainless steel material.
Installation method of the present utility model is:
Become at imbededd case in the cable aperture on housing and coat lubricating grease.According to the diameter of institute's distribution cable, adjustment seal modules, peel seal module sandwich layer, until both coordinate completely.Seal modules coats lubricating grease, installs to facilitate and guarantee that sealing closely.
After ground floor seal modules installs, insert one piece of interlayer board, fix the seal modules of this layer.Interlayer board continues the seal modules installing the second layer.In the middle of the seal modules of the second layer, circular hole adds central plug to carry out shutoff.Our second layer is reserved layer, and the cable increased after convenient can be installed easily, does not need perforate again.
After second layer seal modules installs, then insert one piece of interlayer board, fix the seal modules of this layer, finally in sealing pressing gripping members, smear lubricating grease, and be inserted into the top of seal frame.Tight a bolt and 6 just can obtain sealing effectiveness closely.
