The utility model adopts the following technical scheme:
the rubber sleeve protection device comprises a rubber sleeve protection device body, wherein the rubber sleeve protection device body comprises a first section, a second section and a third section which are sequentially connected, the first section and the third section are of cylindrical structures with different diameters, the diameter of the first section is larger than that of the third section, and a wire passing hole is formed in the end portion of the third section.
Specifically, the second section is of a circular truncated cone structure, the diameter of one end of the second section is the same as that of the first section, and the diameter of the other end of the second section is the same as that of the third section.
Further, the outer diameter of the first section is 12.5mm, the inner diameter is 9.4mm, and the outer diameter of the third section is 9mm, and the inner diameter is 4.5 mm.
Specifically, the length of gum cover protection device body is 55 mm.
Specifically, the rubber sleeve protection device body is a hard polytetrafluoroethylene material protection sleeve.
Compared with the prior art, the utility model discloses following beneficial effect has at least:
the utility model relates to a gum cover protection device, the direct protective sheath that increases one deck stereoplasm tetrafluoro material in the gum cover outside. After the protective sleeve is installed, the protective sleeve is tightly attached to the inner rubber sleeve to completely block the external slurry, so that the rubber sleeve is prevented from being expanded by heat, hydrogen embrittlement or corrosion and burning out under the conditions of high temperature and high pressure and high sulfur content at the bottom of a well, and the insulation of a signal wire with the device in a petroleum logging instrument is ensured to be complete.
Further, the purpose that this gum cover protection device body three-section structure reducing set up is exactly in order to let the interior shape and the gum cover overall dimension of gum cover protective sheath coincide completely, and the benefit of design like this can let the gum cover protective sheath inseparabler closely laminate with inside gum cover completely, does not give any passageway of pressing into of outside mud, fully guarantees the break-make and the insulation of inside cable core and copper sheathing and not destroyed.
To sum up, the utility model discloses fundamentally has solved because bottom hole temperature, bottom hole pressure and the interior hydrogen sulfide of well brings the influence of physics and chemical destruction for the inside gum cover of petroleum logging horse tap and petroleum logging instrument, with the lowest cost, most effective means, thoroughly solve the problem of the inside contact pin department of petroleum logging instrument insulating easy destruction thoroughly from the root, really play the secondary guard action to the inside gum cover of petroleum logging instrument, and this device can be long-time temperature resistant 220 ℃, withstand voltage 180Mpa is left and right sides, play the life of the inside inlayer gum cover of extension instrument, really thoroughly solve the ancient problem of the insulating easy destruction of petroleum logging horse tap and petroleum logging instrument contact pin department.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1. a rubber sleeve protection device body; 2. and a wire passing hole.
Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "one side", "one end", "one side", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, the present invention provides a rubber sleeve protection device, wherein a rubber sleeve protection device body 1 is added outside the rubber sleeve, a line passing hole 2 is formed at one end of the rubber sleeve protection device body 1, the line passing hole is in close contact with a core line, and the rubber sleeve is sleeved inside the rubber sleeve, when in installation, the core line is firstly penetrated into the rubber sleeve protection device from the line passing hole, and then the rubber sleeve is penetrated; and finally, the installation of the copper sleeve and the rubber sleeve is completed.
The cable core wire is firstly inserted into the rubber sleeve protective sleeve, then the cable core wire is inserted into the rubber sleeve, and finally the copper sleeve is clamped at the foremost end of the cable core wire, so that the cable core wire becomes the rubber sleeve protective copper sleeve insulation, the rubber sleeve protective sleeve protects the inner rubber sleeve, and finally the secondary protection effect is achieved.
The rubber sleeve protection device body 1 comprises a first section, a second section and a third section which are sequentially connected, wherein the first section and the third section are of cylindrical structures with different diameters, the second section is of a circular truncated cone structure, the diameter of one end of the second section is the same as that of the first section, the diameter of the other end of the second section is the same as that of the third section, the wire passing hole 2 is formed in the end portion of the third section, the passing core wire is arranged in the rubber sleeve protection device body 1, the rubber sleeve is sleeved on the passing core wire, and then the rubber sleeve is fixed on the copper sleeve.
The outer diameter of the first section is 12.5mm, the inner diameter is 9.4mm, the outer diameter of the third section is 9mm, the inner diameter is 4.5mm, the aperture of the wire passing hole 2 is 2.7mm, and the length of the rubber sleeve protection device body 1 is 55 mm.
The rubber sleeve protection device body 1 is a hard polytetrafluoroethylene protection sleeve.
