DETAILED DESCRIPTION

[0009] Embodiment 1, see Figure 1-Figure 10 .

[0010] A plug-in lateral cable crossing device comprises an elevated flange 1, a hanger 2 and a lower plug 3 which are arranged in sequence from outside to inside. The lower plug 3 is fixedly connected to the elevated flange 1 through the hanger 2. The lower plug 3 is vertical and is located at the center of the internal cavity of the elevated flange 1. The lateral crossing device body 4 passes through the side of the elevated flange 1 and the side of the hanger 2 in the horizontal direction and is plugged with the upper end of the lower plug 3. On the one hand, the crossing device body 4 is no longer installed in the hanger 2, but is arranged on the side of the elevated flange 1, which changes the installation position of the crossing device body 4, thereby eliminating the need to adaptively adjust the structure of the Christmas tree above the elevated flange 1 according to the crossing device body 4, thereby improving the applicable scope of the elevated flange 1, the Christmas tree and other related structures; on the other hand, by arranging the lower plug 3 in the center, it is prevented that the downhole cable connected to the lower plug 3 is scraped against the well wall due to eccentricity, resulting in damage and short circuit of the downhole cable, thereby achieving effective protection for the downhole cable.

[0011] like Figure 5As shown, the lower plug 3 includes an upper shell 301, a lower shell 302 and a tail shell 303 connected in sequence from top to bottom, and the three are fixed by threaded connection, wherein the outer sleeve of the tail shell 303 is provided with a locking sleeve 304, the two are in contact with each other and are fixed by screw compression, the locking sleeve 304 and the inner wall of the hanger 2 are connected by threads, and the bottom end of the locking sleeve 304 is formed with a step due to position limiting, so as to ensure that the entire lower plug 3 can be accurately installed in the predetermined position. Multiple O-ring sealing structures are provided between the lower plug 3 and the hanger 2 to ensure the sealing between the two, wherein the O-ring sealing structure is a prior art, and therefore, no further elaboration is required.

[0012] A concave plug-in board 305 is integrally formed on the side of the upper shell 301. Figure 6 As shown, the plug board 305 is provided with three plug holes 306 distributed in an inverted triangle. In this embodiment, the three plug holes 306 also form an equilateral triangle. The interior of the lower plug 3 is provided with three first insulating conductive rods 307 of equal length along the vertical direction. It is worth emphasizing that the first insulating conductive rods 307 are also distributed in an equilateral triangle and the three first insulating conductive rods 307 correspond to the three plug holes 306 one by one, forming a 90° angle respectively.

[0013] The first insulating conductive rod 307 includes a first conductive rod 3071 in the middle and first connecting tubes 3072 on both sides. It should be explained in detail that, in this embodiment, the axes of the first conductive rod 3071 and the first connecting tube 3072 coincide with each other and are integrally formed. The diameter of the first connecting tube 3072 is larger than the diameter of the first conductive rod 3071. The outer side surface of the first conductive rod 3071 is coated with a polyetheretherketone (PEEK) insulating layer, and the outer end surface of the first connecting tube 3072 is formed with a plug interface by an opening.

[0014] The inner side of the plug board 305 is a plane and three insulating shaping members 308 are provided on the inner side of the plug board 305 facing the plug hole 306. The insulating shaping member 308 is cylindrical as a whole and the axis of the insulating shaping member 308 is perpendicular to the inner side plate surface of the plug board 305. Figure 8 As shown, a through hole with a circular cross section is opened at the center position inside the insulating shaping piece 308, and the aperture of the through hole gradually shrinks in the direction away from the plug board 305. The insulating shaping piece 308 is made of polyetheretherketone (PEEK) and has good physical and chemical properties and insulation properties.

[0015] An L-shaped conductive member 309 is provided above the insulating shaping member 308. Figure 7As shown, the conductive member 309 includes a cylindrical conductive cylinder 3091 with an opening at one end, and a cylindrical connecting rod 3092 is provided at the end of the conductive cylinder 3091 away from the cylinder mouth. The connecting rod 3092 and the conductive cylinder 3091 are integrally formed and the two are perpendicular to each other. It should be noted that the insulating shaping member 308 is provided with a limiting groove 3082 at the end away from the plug board 305, and the end of the cylinder mouth of the conductive cylinder 3091 is inserted into the limiting groove 3082 to achieve the fixation of the two. At this time, the cylinder mouth of the conductive cylinder 3091 is directly opposite to the through hole inside the insulating shaping member 211, so that the two are connected and form a complete pin hole; the connecting rod 3092 is inserted into the first connecting cylinder 3072 at the upper end of the first conductive rod 3071, so that the connecting rod 3092 is connected to the first insulating conductive rod 307, thereby completing the conduction of the circuit. In addition, it needs to be further explained that a long conductive part is used between the two outer jacks 306 and the first connecting tube 3072 located at the top, and a short conductive part is used between the single inner jack 306 and the single first connecting tube 3072 located at the bottom. The long conductive part and the short conductive part have the same structure, and the difference lies in the difference in size. Their function is to adapt the jacks 306 and the first connecting tube 3072 at different positions in the same space.

[0016] The armored cable is inserted from the bottom of the lower plug 3 and dispersed into three cable lines 5 extending upward. The ends of the cable lines 5 form stripping heads and are inserted into the first connecting tube 3072 at the lower end of the first insulating conductive rod 307, forming a passage inside the lower plug 3.

[0017] like Figure 5 As shown, EPDM rubber is injected into the upper shell 301 to form an upper insulating molding 310, and an annular friction groove 3081 is opened on the outer surface of the insulating molding 308. The friction groove 3081 increases the contact area between the insulating molding 308 and the surrounding rubber body, effectively preventing the insulating molding 308 from deformation and displacement during use. Epoxy resin is injected into the lower shell 302 to form a middle sealing molding 311, and hydrogenated nitrile is injected into the tail shell 303 to form a lower sealing molding 312. Filling the interior of the lower plug 3 by injection molding can not only improve the integrity of the internal structure of the lower plug 3, but also ensure internal sealing to prevent external moisture, gas or other foreign matter from entering and affecting the lower plug 3.

[0018] like Fig. 9As shown, the lateral passer body 4 includes a front adapter and a rear adapter body independent of the front adapter, the adapter includes an adapter housing 401, the adapter body includes an adapter housing 402 and an adapter locking nut 403, and the adapter housing 402 is threadedly connected to the adapter locking nut 403. A second insulating conductive rod 404, a wire 405, a third insulating conductive rod 406 and an insulating pin 407 are provided in the lateral passer body 4 in a direction away from the raised flange 1, and the wire 405 is reserved with sufficient length.

[0019] There are three second insulating conductive rods 404 distributed in a triangle shape, and the second insulating conductive rods 404 include a second conductive rod 4041. The inner end of the second conductive rod 4041 is provided with a coaxial second connecting tube 4042, and the tube mouth of the second connecting tube 4042 is away from the second conductive rod 4041. The outer end of the second conductive rod 4041 extends outward and protrudes from the traverser body 4 to form a pin 4043. It is worth emphasizing that the pin 4043 corresponds to the socket 306 on the plug board 305 one by one. When plugging, the pin 4043 is inserted into the socket 306.

[0020] The third insulating conductive rod 406 includes a third conductive rod 4061. The third conductive rod 4061 is provided with a coaxial second connecting tube 4042 at one end facing the second insulating conductive rod 404. The tube mouth of the second connecting tube 4042 faces the second insulating conductive rod 404. The outer sleeve of the other end of the third conductive rod 4061 is provided with an insulating pin 407. The insulating pin 407 is plugged into a ground bent plug (not shown in the figure) to realize power transmission of the ground cable.

[0021] like Fig. 9 As shown, the second insulating conductive rod 404 and the third insulating conductive rod 406 are connected through the wire 405. The wire 405 has stripping heads at both ends, one end of which is inserted into the first connecting tube 3072, and the other end is inserted into the second connecting tube 4042. The wire 405, the end of the second insulating conductive rod 404 close to the wire 405, and the end of the third insulating conductive rod 406 close to the wire 405 are covered with an insulating reinforcement layer 408. The insulating reinforcement layer 408 has three layers from the inside to the outside, wherein the inner layer is a polytetrafluoroethylene pressure-sensitive tape, the middle layer is a polytetrafluoroethylene pressure-sensitive tape, and the outer layer is a heat shrinkable tube. In this embodiment, the heat shrinkable tube is made of polyvinylidene fluoride (PVDF). The insulating reinforcement layer 408 is used to seal and insulate the connection between the second insulating conductive rod 404, the wire 405, and the third insulating conductive rod 406 to ensure stable transmission of electricity.

[0022] The adapter housing 401 is internally threaded with a cylindrical sealing body 409, and the second insulating conductive rod 404 is inserted into the sealing body 409. A plurality of O-ring sealing structures are provided between the two. Similarly, the cylindrical sealing body 409 and the adapter housing 401 are also provided with a plurality of O-ring sealing structures. The front side of the sealing body 409 is injection-molded with EPDM rubber to form an adapter front end insulating molding 410, and the rear side of the sealing body 409 is injection-molded with epoxy resin to form an adapter rear end sealing molding 411. The interior of the adapter housing 401 is filled by the sealing body 409, the adapter front end insulating molding 410, and the adapter rear end sealing molding 411, which can not only locate and limit the second insulating conductive rod 404, but also protect the second insulating conductive rod 404. The front end of the adapter front end insulating molding 410 forms a truncated cone-shaped plug-in flange around the second conductive rod 4041. During the plug-in process, the plug-in flange is just inserted into the through hole inside the insulating molding 308, thereby forming a seal.

[0023] A step 4021 is formed on the outer surface of the adapter housing 402, and the inner side of the step 4021 is the adapter body plug-in end. A pressure plate 412 is provided on the adapter plug-in end. The pressure plate 412 is sleeved on the outer periphery of the adapter housing 402, and the pressure plate 412 is engaged with the step 4021 and is limited by the step 4021.

[0024] The side surfaces of the lifting flange 1 and the hanger 2 are respectively provided with a first connection hole 101 and a second connection hole 201 corresponding to the plug plate 305. The lateral passer body 4 needs to pass through the first connection hole 101 and the second connection hole 201 and then be plugged with the lower plug 3 inside the hanger 2. Specifically, the adapter at the front end of the lateral passer body 4 is inserted into the second connection hole 201, and the plug end of the adapter body is inserted into the first connection hole 101.

[0025] The surface where the first connecting hole 101 on the lifting flange 1 is located is the installation surface, and the installation surface is a plane. The plate surface of the pressure plate 412 is in contact with the installation surface, and the lateral crosser body 4 and the lifting flange 1 are pressed and fixed by the pressure plate screw 413 and the pressure plate 412 to prevent the lateral crosser body 4 and the lifting flange 1 from offsetting or detaching.

[0026] After installation, the wire 405 inside the adapter housing 402 is bent, that is, the relative distance between the adapter and the lateral transit device body can be adjusted according to actual needs. By setting a flexible, bendable wire 405 to connect the second insulating conductive rod 404 and the third insulating conductive rod 406, the front adapter and the rear adapter body can be relatively displaced and rotated. On the one hand, when there is an installation or manufacturing error in the jack 306, the adapter can be rotated so that the pin 4043 and the jack 306 are aligned and then plugged in. On the other hand, when there is an installation error between the lifting flange 1 and the hanger 2, that is, the first connecting hole 101 and the second connecting hole 201 are in a non-facing state, the adapter and the adapter body can also complete the plugging of the lower plug 3 and the lateral transit device body 4 in a non-facing state, thereby improving the installation fault tolerance between the lateral transit device body 4 and the lower plug 3.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
