Description
Technical field
The invention belongs to geothermal well-pipe technical field, particularly relate to a kind of geothermal well-pipe with protection cable feature.
Background technology
Due to geothermal well submersible pump work time, need invade bubble in GEOTHERMAL WATER, so just make submersible pump cable be in high temperature for a long time, in the GEOTHERMAL WATER of highly corrosive, invade bubble through long-term, there is crackle in the accelerated ageing of cable surface insulating layer, makes its lost of life; Usually the water level of hot well is at about-100 meters, well casing is generally at 6 meters one section, 20 more piece well casing guarantees are so just needed to have water level and adopt mating of discharge, usual submersible pump is connected with well casing, and be arranged on the lowermost end of well casing, submersible pump cable just draws up along well casing colligation, will through more than 20 flange junctions, because well casing flange is more much bigger than well casing diameter, add cable to pass through in flange periphery again, when submersible pump is gone into the well, frequent and wall friction, or because operated by personnel is improper, very easily because mechanical force damages cable; Submersible pump cable is caused to damage phenomenon.
Summary of the invention
The present invention for solve in known technology the technical problem that exists and provide a kind of structure simple, easy to install, prevent cable from wearing and tearing, improve the geothermal well-pipe with protection cable feature of lower well operations.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
A kind of geothermal well-pipe with protection cable feature, comprise well casing, the two ends of well casing are welded with flange respectively, flange is provided with and is laid with connecting hole, it is characterized in that: between the flange at described two ends, well casing outer wall is fixed with cable installation, described cable installation comprises cable, the two ends of cable are provided with male and female plug, described male and female plug is inserted in the installing hole of two end flanges, the periphery of male and female plug is filled with the heatproof oil resistant insulating body of fixing male and female plug, and the two ends of described isolator are respectively equipped with rubber seal; The external surface of described well casing is provided with several fixed component for clamping fixed cable.
The present invention can also adopt following technical measures:
Described fixed component comprises the connecting portion be connected with geothermal well-pipe, and the outer end of described connecting portion is provided with cable and clamps portion, and the inner surface that described cable clamps portion is provided with protective jacket.
The described cable portion of clamping adopts Split type structure, namely has fixing split body and movable split body, and after two lobe bodies are connected to form by connector, its inner chamber is consistent with the exterior cross-section of cable.
Described connector is bolt, and namely the two ends of the described cable fixing split body and movable split body that clamp portion are bolted.
Described connector is jointed shaft, and the fixing split body that namely described cable clamps portion is connected by jointed shaft with movable split body one end, and the other end adopts bolt or padlock.
Described cable adopts waterproof bus.
The advantage that the present invention has and good effect are: because the present invention adopts technique scheme, cable and geothermal well-pipe are fabricated to integrative-structure, going into the well, cable in connection well casing process has once docked with well casing, convenient quick, thus avoid when submersible pump is gone into the well, cable often and wall friction, thus solves the problem of submersible pump cable wearing and tearing.In addition, in order to prevent electric leakage, the periphery of male and female plug is filled with the heatproof oil resistant insulating body of fixing male and female plug, is respectively equipped with rubber seal at the two ends of isolator; In order to ensure that cable is more firm, the external surface of well casing is provided with several fixed component for clamping fixed cable.Therefore the present invention has the function of stronger protection cable, but also improves and to go into the well operating efficiency, reduces intensity of having worked, in addition the present invention also have structure simple, reasonable in design, be easy to processing and manufacture, be convenient to the advantages such as transport.
