The heat-insulation layer encircles the PVC pipe, the anticorrosion layer is coated on an outer layer of the heat-insulation layer, the metal heat-conducting layer can generate heat under the effect of the solar cell panel, is a netted resistance layer and is connected with wires, resistance wires are longitudinally and transversely staggered on one another to form the netted resistance layer, and the other ends of the wires and the solar cell panel are connected with one another to form a closed circuit. The heat-insulation PVC plastic pipeline has the advantages that currents can be generated by the solar cell panel under the sun illumination conditions in the daytime and can be conducted to the netted resistance layer via the wires, electric energy can be converted into heat energy, the heat can be sustained at night by the aid of the heat-insulation layer, and accordingly freeze protection effects an be realized for the PVC pipe without external power sources; owing to protection of the anticorrosion layer which is the outermost layer, the heat-insulation PVC plastic pipeline can be buried under the ground, and is excellent in water resistance, impact resistance, anticorrosion property and flame resistance, simple in structure and easy to manufacture.
Description
Technical field
The invention belongs to PVC plastic pipeline field, especially relate to a kind of insulation PVC plastic pipeline.
Background technique
In existing technology, the pipeline such as foggara, drain pipe generally adopts PVC material to make, but this water pipe due to its freeze-proof bad, in easy bursting by freezing in the winter of cold, cause large-area spilling water to run and emit phenomenon, bring the impact using and go on a journey to resident or industry.Disclose so a kind of antifreezing water pipe in existing patent specification CN202580447U, be wound with resistance silk ribbon in the outer felt of water pipe, resistance silk ribbon is connected with power supply, and power supply is by the switch control rule on-off of band temperature transducer.When temperature reaches certain low temperature, the switch connection power supply of band temperature transducer, makes resistance silk ribbon heating power and melts and stop on water pipe icing, thus the use safety of protection water pipe.But this structure is not provided with thermal insulation apparatus and protective gear in resistance wire outside, runs off very soon, needs continual energising, cause the waste of electric energy, and directly cannot imbed underground at the heat in winter of cold.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of insulation PVC plastic pipeline, especially by solar panel heat conduction, can be incubated, matcoveredn, can buried heat-preservation plastic pipeline.Automatic heat preserving effect can either be reached, and durable for a long time.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of insulation PVC plastic pipeline, comprises pvc pipe, around the thermal insulation layer of pvc pipe, is coated in the outer field anticorrosive coat of thermal insulation layer, also comprises the metal guide thermosphere being looped around pvc pipe tube wall, described metal guide thermosphere insulation layer parcel.
Further, described metal guide thermosphere is mesh resistive layer, and thickness is 0.05mm-0.1mm, and material is the one in nichrome, Fe-based perovskite-like oxide.
Further, described mesh resistive layer thickness is 0.05mm, and material is nichrome.
Further, described mesh resistive layer is by the crisscross resistance net formed of nichrome resistance wire.
Further, described insulation PVC plastic pipeline also comprises the wire be connected with the joint of described mesh resistive layer, and the described wire the other end is connected with solar panel, forms closed-loop path.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, daytime shines upon down, electric current is produced into by solar panel, electric current conducts in mesh resistive layer by wire, electric energy changes into heat energy by mesh resistive layer, make heat continue by thermal insulation layer in the evening, to reach the antifreeze effect of pvc pipe, without the need to ABAP Adapter, meanwhile, due to outermost anticorrosive coat, underground can be imbedded, give its good water resistence, impact resistance, anti-corrosive properties and flame retarding, structure is simple, is easy to produce.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are illustrated:
As shown in Figure 1, insulation PVC plastic pipeline of the present invention is respectively pvc pipe 4, metal guide thermosphere 5 from inside to outside, thermal insulation layer 6 and anticorrosive coat 3, also comprise the wire 1 be connected with the joint of described metal guide thermosphere 5, described wire 1 the other end is connected with solar panel 2, forms closed-loop path.
Wherein, metal guide thermosphere 5 is mesh resistive layers, thickness is 0.05mm-0.1mm, material is the one in nichrome, Fe-based perovskite-like oxide, and after test, it is the nichrome that 0.05mm is thick that the present embodiment preferably chooses metal guide thermosphere 5, most suitable temperature can be ensured, both produced enough heats, and be unlikely to again burning, and be easily wrapped in the outside of described pvc pipe 4.
As shown in Figure 3, by crisscross for nichrome resistance wire, form nichrome mesh resistive layer 5, pvc pipe 4 thermally equivalent can be made.Two end connectors of nichrome resistance wire are connected with wire 1, form closed-loop path with solar panel 2.
Thermal insulation layer 6 chooses the thick polystyrene foam plastics layer of 1cm, can ensure both to have reached heat insulation effect, the heat that a part of metal guide thermosphere 5 that can leave again produces, and avoids the temperature of generation too high and causes thermal insulation layer 6 to burn.
Preferably, the anticorrosive coat 3 be coated on thermal insulation layer 6 chooses epoxide coal bituminous layer, has excellent anticorrosion, waterproof, shock-resistant, fire-retardant effect.
In the present embodiment, pvc pipe 4 is carried out sturdy parcel by nichrome mesh resistive layer, and polystyrene foam plastics layer is wrapped in the outside of nichrome mesh resistive layer, applies the epoxide coal bituminous layer of one deck in the outside of polystyrene foam plastics layer.
As shown in Figure 2, described insulation PVC plastic ducted nichrome mesh resistive layer 5 is connected with wire 1 working procedure, and the other end of wire 1 is connected with solar panel 2.Sunlight is on solar panel 2, generation current, electric current conducts in nichrome mesh resistive layer 5 by wire, electric energy conversion is heat energy by nichrome mesh resistive layer, polystyrene foam plastics layer pins heat, reach heat insulation effect, nichrome mesh resistive layer is played a protective role simultaneously, underground can be imbedded, the tubing of epoxide coal bituminous layer to inside of outermost surface coating plays anticorrosion, waterproof, shock-resistant, fire-retardant effect, make heat continue by polystyrene foam plastics layer in the evening, to reach pvc pipe 4 in antifreeze effect at night, without the need to ABAP Adapter.
