In recent years, wired drilling directional drilling technique is applied to geological prospecting industry by increasing, wherein,
It is one of important composition for completing this technique to take an overall view of water swivel.
It is used for the cable to orientation instrumental transmission electric signal during wired drilling directional drilling is carried out, in bottom hole drilling tool
Line must pass connection display instrument from water swivel, and at the same time, water swivel guarantees lasting to be provided in drilling hole again
Flushing liquor circulates, and prevents flushing liquor from spraying.Therefore, existing conventional geological drilling water swivel must be with connection special high-pressure hydraulic cylinder
It is connected, plays sealing function.
, all must be in advance by deviational survey cable 21 from the top of high-pressure hydraulic cylinder 22 when implementing wired drilling deviational survey directional drilling every time
Endoporus penetrate, through the conventional centre bore of water swivel 23 after pass from the centre bottom of vertical shaft drilling rod 24, then connect with deviational survey inserting tube
Head connection, deviational survey cable 21 is sealed using high-pressure hydraulic cylinder 22, realized with deviational survey positioning operation is bored, as shown in Figure 1.Orientation knot
Shu Hou, again cable connector block, deviational survey cable 21 extracted out, lays down high-pressure hydraulic cylinder 22, recover normal drilling process.It is this
The process of " installation-connection-orientation-disconnection-dismounting " frequent connecting cable joint, take a substantial amount of time and energy,
For the extremely simple and crude field drilling operation scene of condition, it is difficult to ensure the quality of connection and stable performance of cable and joint
Property.
Utility model content
The purpose of this utility model is：For overcome the deficiencies in the prior art, under conditions of ensureing to seal, there is provided a kind of
Through logical cable water swivel assembly, just inclinometer can directly be proposed water swivel without blocking cable, reduce the connection of instrument
Process, the time is saved, reduce necessary equipment.
To achieve the above object, the technical solution of the utility model is：
A kind of through logical cable water swivel assembly, including hermetic unit, fixed part and rotating part, the hermetic unit
Including plug gland, perforated rubber stopper, stand with holes, upper shell, bend pipe, rubber stopper is placed in above stand, and stand is placed in upper casing
In vivo, plug gland, which covers, seals upper shell on upper shell, and bend pipe rigid connection is in the middle part of upper shell, with being connected inside upper shell；
The rotating part includes spring, pressure-bearing plate, core pipe, seal assembly, needle bearing, thrust bearing, mandrel, the core pipe and core
Axial filament button couples, and core pipe is installed spring, pressure-bearing plate and seal assembly, the mandrel and installed successively from top to bottom successively from top to bottom
Needle bearing and thrust bearing；The fixed part include it is small lock emit, greatly lock emit, connected body, lower house, hermetic oil seal, lower casing
Body bottom is equipped with hermetic oil seal, and the rotating part is fixed in lower house by connected body, and hermetic unit is emitted solid by small lock
It is scheduled in connected body, big lock is emitted for the body that is fixedly connected.
Further, the plug gland is divided into band centre bore and without two kinds of specification of centre bore.
Further, grease nipple is installed on the lower house.
Further, the seal assembly is at least two sealing rings.
Further, the upper shell, central siphon, the internal diameter of mandrel are 38~42 millimeters.
As a result of such scheme, the beneficial effects of the utility model are：The utility model personality activity is strong, practical
Property it is high, simplify structure, can first assemble deviational survey inserting tube and form assembly, can overall injection and salvaging, save the time, improve and make
Industry efficiency；Good integrity, just inclinometer can directly be proposed water swivel without blocking cable, reduce the connection process of instrument,
Unnecessary consumptive material is saved, it is cost-effective；It is compact-sized, it is in light weight, reduce the bending moment of vertical shaft drilling rod；Good airproof performance,
Tight using manual bolts rotation, compressing rubber stopper, which shrinks, reaches sealing function, does not use special hydraulic pump and hydraulic line
Sealed, reduce auxiliary machine tool expenditure.
