Utility model content
The purpose of this utility model is exactly to solve the above problem existing in the prior art, there is provided a kind of buried cable fire prevention
Waterproof seal；The utility model can reliably ground-to-ground above section cable in face be protected, and avoids ground with upper bit
Destruction, while to ground and underground piping part sealed reliable, prevent the cable of ground link position and under ground portion to be subject to
Rainwater immerses, mouse enters security risk caused by subway.
The utility model solve technical problem technical solution be：
A kind of buried cable fire-proof and water-proof sealing device, including protection sleeve pipe, protection sleeve pipe lower end pass through basis and basis
Under ground, cable passes through from protection sleeve pipe, and protection sleeve pipe upper end is equipped with sealing structure.
The sealing structure includes sealing shroud, sealing cover, and sealing shroud is connected with sealing cover, outside the endoporus and cable of sealing cover
Circle sealing coordinates.
Lug boss, the endoporus and raised portion fits of sealing shroud are equipped among the lower part of sealing cover.
Seal is equipped with the endoporus of lug boss lower face position.
The endoporus of the sealing shroud is conical bore, and the lug boss of sealing cover is circular conical surface, and conical bore coordinates with circular conical surface.
The sealing shroud lower end is connected with protection sleeve pipe upper end by thread fitting.
Groove is equipped with the basic cable slot of protection sleeve pipe link position, is equipped with gland on groove, in gland
Between the sealing of hole and protection sleeve pipe external cylindrical surface coordinate, the external cylindrical surface of gland coordinates with the groove inner periphery sealing on basis,
The groove location that protection sleeve pipe external cylindrical surface is sealed in gland lower face is equipped with gasket.
The sealing structure is expansion fire-proof fluid sealant, expansion fire-proof fluid sealant protection sleeve pipe end and cable it
Between formed predetermined thickness plugged zone.
The beneficial effects of the utility model：
1. the utility model can reliably ground-to-ground above section cable in face be protected, waterproof, fire prevention, mouse bite preventing effect
It is good, avoid destruction of the ground with upper bit, while to above ground portion sealed reliable, prevent ground link position and under ground portion
Cable is subject to rainwater immersion, mouse to enter security risk caused by subway.
2. be equipped with lug boss by the lower part of sealing cover, the endoporus and raised portion fits of sealing shroud, under lug boss lower face
Seal is equipped with the endoporus of portion position.Ensure that top seal is reliable, avoid dangerous caused by rainwater intrusion from passing through sealing shroud
Endoporus be conical bore, the lower lobes of sealing cover are circular conical surface, conical bore and circular conical surface coordinate it is more accurate, can be to lower part
The effect of seal applying power, better tightness, water resistance are more reliable.
3. casing air bag is connected with the periphery of cable using the mode such as Nian Jie, sealing is strengthened by air bag, avoids rainwater
Cable underground piping is downwardly into, while on the basis of can the moiety by weight of cable be delivered to, reduces cable excessive sag and draws
The bending that rises and the defects of deformation and upper connection stress less reliable.
4. by forming the expansion fire-proof sealant sealing blocking layer of predetermined thickness between protection sleeve pipe end and cable, together
When play waterproof and fireproof function.
