Abstract

The utility model relates to a compound fiberglass reinforced plastics cable protection bushing. A connecting port is arranged at one end of a pipe body, a seal ring is arranged in the connecting port, the weight ratio of the unsaturated resin base material and the glass fiber cloth of the pipe body material is 4 to 4.5:5.5 to 6, semicircle clip slots are arranged at the both ends of a pipe pillow, or a splicing and inserting groove and a splicing and inserting ridge is arranged on a corresponding inserting edge, and the pipe body can be clipped in the semicircle clip slot of the pipe pillow. The cable protection bushing of the utility model has the advantages that the weight is light, the cost is low, the intensity is high, the current-carrying capacity is large, the thermal resistance is weak, the heat resisting, heat radiation, flame retardant and cold tolerant performances are good, the application range is wide, and the operation is secure and convenient, thus the utility model can be generalized to be used.

Description

The cable-protecting composite GRP pipe cover

Technical field

The utility model relates to a kind of cable-protecting composite GRP pipe cover.

Background technology

Along with the high speed of urban construction is carried out, City Buried Pipeline is more and more, and becomes increasingly complex, and free space is also more and more littler, and this requires the science of programmingization of urban underground space.Traditional city cable construction is adopted to dig and is established plastic tube or pipe of cement or coating steel pipe, or build by laying bricks or stones and mix the method cable laying of doubting native cable trough and electric power tunnel, but all there are major defect in above-mentioned construction material and method, the plastic tube serviceability temperature is low, intensity difference is embedded in undergroundly under the effect of cable operating temperature 60～70 degree and water for a long time, and plastic tube can produce decomposition, intensity decreases is aging, and is yielding and break under the ambient pressure effect.Coating steel pipe is perishable, yarn non-insulating material again, and easily operation produces interference to magnetic to cable, and matter high price height, and construction is inconvenient, and the electric welding reverse interface easily makes cable skin pull.And the mixed doubtful native cable trough engineering time is long, often will open cover plate when maintaining and safeguarding increases labour intensity, also influences the urban transportation and the appearance of the city, and easy ponding easily makes cable bad in the cable trough, be the good living space of muroid on the other hand in the cable trough, the infectivity disease.The electric power tunnel engineering time is long, and construction investment is big, and fire-fighting and ventilation are difficult to solve.

Summary of the invention

The purpose of this utility model provides a kind of cable-protecting composite GRP pipe cover, and it is in light weight that it is had, and cost is low, the intensity height, and ampacity is big, and thermal resistance is little, heat-resisting heat radiation and fire-retardant and cold tolerance good, and have the use face width, advantage safe and convenient to use.The utility model adopts an end of body to be provided with connector for this reason, be provided with sealing ring in the connector, the material unsaturated-resin base-material of body and glass fabric are 4～4.5: 5.5～6 by weight, pipe pillow two ends are provided with half garden draw-in groove, or be provided with at corresponding insert edge and piece together insert groove and piece together and insert tongue, body can block and crouches in managing the half garden draw-in groove of resting the head on.The said structure design has realized the purpose of this utility model.

The utility model has the advantages that the intensity height, be used for the runway direct-burried, need not to add concrete cover, intensity generally exceeds more than 6 times than the plastics and the nylon tube of condition of equivalent thickness.Ampacity is big, and thermal resistance is little, and perfect heat-dissipating does not have any adverse effect to the operate as normal of cable.Insulation, non magnetic, no eddy current loss and galvano-cautery, energy-conservation are applicable to single stamen cable laying, corrosion-resistant can the use in the high salinity area.Body has flexibility, and is supporting again with flexible joint, can resist extraneous weight and foundation settlement.Fire-retardant, heat resistance good, can be under the high temperature of 120 degree long-term use indeformable.Cold tolerance is good, can use under negative 30 degree, and the intensity and the flexibility of pipe do not change.Smooth stingless, easily wear cable, not scratch cable, good airproof performance, cost is low, and cost only is 20% of traditional structure, and is in light weight, and installation is convenient, and has the use face width, advantage safe and convenient to use.

Embodiment

As Fig. 1～shown in Figure 3, a kind of cable-protecting composite GRP pipe cover is made up of

body

3 and 7 on pipe pillow, and an end of body is provided with connector 1, establishes fixedly rib 2 in the connector, is convenient to two pipes and plugs together the location.Be provided with sealing ring 6 in the connector, the material unsaturated-resin base-material 5 of body and glass fabric 4 are 4～4.5: 5.5～6 by weight, pipe pillow two ends are provided with half garden draw-in groove 8, or are provided with to piece together at corresponding insert edge and insert groove 9 and piece together and insert tongue 10, and body can block and crouches in managing the half garden draw-in groove of resting the head on.

Described unsaturated-resin base-material is by 100 parts of unsaturated-resins, 5 parts of antimonous oxides, and 5～15 parts of deca-BDEs, or 10～15 parts of oxidized paraffin waxs, 0.6～3 part in cobalt water, talcum powder, or quartz sand, or 5～15 parts in calcium carbonate, methylethylketone is mixed and made into for 1～4 part.

Described sealing ring is between the insertion mouth of pipe of connector and corresponding another body mouth.Base-material of the present utility model adopts unsaturated-resin, can adopt market to sell 191 types, 196 types, or 189 type unsaturated-resins, and the unsaturated-resin of above-mentioned model can use separately, also can mix use in proportion.

Described glass fabric is middle alkali, or does not have alkaline glass fabric, also can use with thick roving.Mould of the present utility model adopts the seamless steel pipe processing of 45 models, stamps butter or machine oil on mould, spreads mylar.Glass fabric in the base-material that is immersed in preparation and yarn are wrapped on the mould, mould is made garden Zhou Xuanzhuan in winding process, and per minute rotating speed 60～200 changes, usually according to different product thickness, the glass fabric of the different numbers of plies and yarn in the winding, the number of plies is 9～20 layers usually.After winding finishes, treat to solidify after 10 minutes and finish, product is lifted to the demoulding on the ingot stripper, with cutting machine product two ends surplus is removed then and got final product.The effect of pipe pillow is the stay pipe body, and with the supporting use of body, pipe pillow shown in Figure 2 is separated up and down and supported body between two-layer body.The pipe that Figure 2 shows that the single body of support is rested the head on, and the outer end is positive square, and the inner is a garden shape, and design is separated at the middle part, and the corresponding insert edge of separation is provided with the slotting groove 9 of assembly and inserts tongue 10 with piecing together, and when the assembly of the slotting tongue insertion of assembly another side was inserted in the groove, pipe was rested the head on fastening support body.

In a word, have in light weightly with cable protection pipe cover of the present utility model, cost is low, the intensity height, and ampacity is big, and thermal resistance is little, heat-resisting heat radiation and fire-retardant and cold tolerance good, and have the use face width, advantage safe and convenient to use can be promoted the use of.
