Technical field
The present invention relates to cable water seepage-proof tech field more particularly to a kind of cable fluid proof seal device and antiseep are close Encapsulation method.
Background technique
Submersible pump is the important equipment of deep-well water lift.Entire unit pulls the plug work when use, and underground water is extracted To earth's surface, it is widely used in domestic water, mine is speedily carried out rescue work, industry cooling, field irrigation, seawater lift, steamer tune load field.By It needs to be placed on underwater work for a long time in submersible pump, so requiring its sealing performance very strict.
Cable in the prior art is usually the similar rope that by several or several groups of conducting wires (every group at least two) are twisted The structure of strand, mutually insulated between every group of (root) conducting wire, and be often twisted into around a center, entire outside is surrounded by height absolutely The coating of edge.Cable has interior energization, the feature of external insulation.Due to outside each conducting wire by wire insulation carry out every From and most of conducting wire is all cylindrical structure, and such structure makes between every group of conducting wire of cable, wire insulation and entire outer There are tiny gaps between portion's insulating layer;When being used for submersible pump, these slight gaps can draw cable in the prior art The leakage for playing water, so that the risk of submersible pump unit inner inlet can be caused.Seriously threaten the safe operation of submersible pump. In consideration of it, how to provide a kind of cable fluid proof seal device and fluid proof seal method is that those skilled in the art need to solve Technical problem.
Summary of the invention
For above-mentioned shortcoming in the prior art, the present invention provides a kind of cable fluid proof seal device and antiseepages Leak encapsulating method.
The present invention using following technical scheme in order to solve the above technical problems, realized:
A kind of cable fluid proof seal device, including cable are designed, is equipped with several conducting wires, each institute in the cable It is arranged with a layer conductor insulating layer outside the conducting wire stated, is arranged with one layer of external insulation outside the wire insulation, it is described Conducting wire be set in insulating support, the insulating support shape be circular configuration, be uniformly provided with several bracket holes thereon, The bracket holes are connected to the edge of insulating support by connection gap;It is arranged with heat-shrinkable T bush outside the insulating support, Encapsulating has epoxy pouring sealant in the thermal shrinkable sleeve;And the both ends of the heat-shrinkable T bush are wound with sealant tape.
Preferably, the number of the bracket holes is not less than the number of conducting wire in the cable, to ensure that a conducting wire is not equal It is fixed by a bracket holes.
Preferably, the bracket holes section is that circular configuration is avoided with reducing the coefficient of friction between bracket holes and conducting wire Conducting wire is fractureed by bracket holes.
A kind of cable fluid proof seal method is designed, is included the following steps:
Step 1: the entire external insulation at position among cable is peelled off into certain length first;It is further continued for peelling off The wire insulation of conducting wire is peelled off on the position of external insulation;
Step 2: each conducting wire is each passed through corresponding connection gap, and conducting wire is stuck in the bracket of insulating support Kong Shang;
Step 3: heat-shrinkable T bush is nested on the position that the entire external insulation of cable is stripped with heating, then is used The side junction of sealant tape winding external insulation and heat-shrinkable T bush;Then epoxy is perfused into heat-shrinkable T bush in the other end Casting glue;
Step 4: when the amount of epoxy pouring sealant injection is approached with heat-shrinkable T bush plane to be flushed, stopping continues to be perfused Another end is wound the junction of external insulation and heat-shrinkable T bush by epoxy pouring sealant with sealant tape.
A kind of cable fluid proof seal device proposed by the present invention and fluid proof seal method, beneficial effect are: this hair Bright apparatus structure is simple, and each of cable conducting wire is stuck in corresponding bracket holes first, then by bracket holes It is coated in heat-shrinkable T bush, and fills epoxy pouring sealant in heat-shrinkable T bush;Finally sealant is wrapped at the both ends of heat-shrinkable T bush Band;Fine gap between each clogging conducting wire of the epoxy pouring sealant filled, effectively ensures that external source will not be suitable Insulation between gap flow into submersible pump in;The insulating properties of submersible pump is substantially increased, and then improves submersible pump Service life.
Detailed description of the invention
The present invention is described in further detail for embodiment in reference to the accompanying drawing, but does not constitute to of the invention Any restrictions.
Fig. 1 is the structural schematic diagram of apparatus of the present invention;
Fig. 2 is the structural schematic diagram of insulating support in apparatus of the present invention.
In figure: cable 1, conducting wire 2, wire insulation 3, external insulation 4, insulating support 5, bracket holes 6, connection gap 7, Heat-shrinkable T bush 8, epoxy pouring sealant 9, sealant tape 10.
Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this The embodiment of invention, every other implementation obtained by those of ordinary skill in the art without making creative efforts Example, belongs to protection scope of the present invention.
Refering to shown in attached drawing 1- attached drawing 2, a kind of cable fluid proof seal device of the invention, including cable 1, the cable It is equipped with nine conducting wires 2 in 1, a layer conductor insulating layer 3, the wire insulation 3 are arranged with outside conducting wire 2 described in each It is arranged with one layer of external insulation 4 outside, the conducting wire 2 is set in insulating support 5, and 5 shape of insulating support is circle Shape structure, is uniformly provided with nine bracket holes 6 thereon, and the bracket holes 6 are connected to the side of insulating support 5 by connection gap 7 Edge, 6 section of bracket holes are circular configuration;Heat-shrinkable T bush 8, the heat-shrinkable T bush 8 are arranged with outside the insulating support 5 Interior encapsulating has epoxy pouring sealant 9;And the both ends of the heat-shrinkable T bush 8 are wound with sealant tape 10.
A kind of cable fluid proof seal method of the invention, includes the following steps:
Step 1: the entire external insulation 4 at the intermediate position of cable 1 is peelled off to the length of 350m first;It is further continued for shelling It goes among the external insulation 4 of 350m length, the wire insulation 3 apart from each 25mm in both ends, length 300mm is peeled off;
