Embodiment
Below in conjunction with test example and embodiment, the present invention is described in further detail. But this should not being interpreted as, the scope of theme of the present invention is only limitted to following embodiment, all technology realized based on content of the present invention all belong to the scope of the present invention.
As shown in figs. 3-10, a kind of non-rotating joint connected for down-hole electrical module of the present invention, comprise male joint 1, female joint 2, block 3, adapter sleeve 4, described male joint 1 is processed with locating surface 1, male spline 12, block locating surface 13, installation neck 14, appearance line chamber 15, joint 1 and sealing-ring groove 17 is installed;Being processed with locating surface 2 21, internal spline 22, joint 2 23 and ring groove 24 in described female joint 2, female joint 2 one end is also provided with outside screw 25; Described block 3 cuts open annulus for two halves, and it is processed with locating surface 3 31 and locating surface 4 32; Described adapter sleeve 4 is cylindrical shroud tubular, and is processed with locating surface 5 41, screw hole 42 and internal thread 43.
When non-rotating joint is installed, as shown in Figure 11,12, first adapter sleeve 4 is sleeved on the installation neck 14 in male joint 1 in advance, and the sealing-ring that sealing-ring 6 is arranged on male joint 1 surface is installed in groove 17, prevent drilling fluid from entering male joint 1 and female joint 2 inside from non-rotating joint, and then it is inner to flow into down-hole electrical module 7, then the cable 1 passed from male joint 1 and female joint 2 inside respectively, cable 2 82 are carried out wiring; After completing the connection of cable 1, cable 2 82, the male spline 12 of male joint 1 is inserted in the internal spline 22 of female joint 2 and coordinates, it is possible to prevent male joint 1 and female joint 2 produces relative rotation, until the locating surface 2 21 in locating surface 1 and female joint 2 contacts with each other in male joint 1; Two halves cut open circular block 3 again be enclosed within the installation neck 14 of male joint 1, and the locating surface 3 31 of block 3 is abutted against on the block locating surface 13 of male joint 1; Again the internal thread 25 of the internal thread 43 of adapter sleeve 4 and female joint 2 is cooperatively interacted and screws, until the locating surface 5 41 on adapter sleeve 4 and the locating surface 4 32 on block 3 mutually near, thus limit male joint 1 and female joint 2 produces relative movement vertically; And then tightening screw 5 is screwed in the screw hole 42 on adapter sleeve 4, and block in female joint 2 upper annular groove 24, it is possible to prevent between the adapter sleeve 4 that is threaded and female joint 2 because screw thread coming off of losing efficacy and cause, so far, just completes the connection of non-rotating joint. In addition, the appearance line cavity volume of the inside, close joint 1 one end of male joint 1 is relatively greater than the cavity volume volume of non-rotating joint one end, and the dish of the long cable of mistake being convenient in the appearance line chamber 15 of male joint 1 and female joint is put, and avoids the problem of twisted wire.
When described non-rotating joint is when accessing down-hole electrical module, by the joint 1 in male joint 1 and the joint 2 23 in female joint 2, male joint 1 and female joint 2 are connected to the leading-out terminal of down-hole electrical module 1, down-hole electrical module 2 72 respectively, and then the cable connected is passed from the inner chamber of male joint 1 and female joint 2 respectively.
It should be noted that, as shown in Fig. 4,8,10, in order to ensure the smooth installation of non-rotating joint, the installation neck 14 in male joint 1 must have enough installation length L, could ensure block 3 and the installation of adapter sleeve 4; The maximum outside diameter d at male spline 12 place in male joint 11The aperture D that should be not more than locating surface 5 41 place of adapter sleeve 4, the aperture D at locating surface 5 41 place of above-mentioned adapter sleeve 4 should be less than the outside diameter d at locating surface 3 31 place of block 32。
