Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the withstand voltage pipe close of cable duct bank of the present invention.
In above accompanying drawing: 1, seal ring; 2, end casing; 3, standing screw; 4, set screw nut; 5, filling tube; 6, valve; 7, position-limited lever; 8, screw rod is installed.
Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described.
Embodiment one: shown in accompanying drawing 1, for carrying out the withstand voltage pipe close of cable duct bank of shutoff to its end in a kind of comb being arranged at cable passage engineering, comprises body, seal ring 1, axially locating assembly, limit assembly and operating component.
Body is in more flat cylindrical, and it is made up of elastic material (as rubber etc.), and the inside of body forms the injection pot for filling in filler.The axis of the central axis of this body with its want the axis of the cable duct bank of shutoff to parallel.
Seal ring 1 is also made up of elastic material, this circumferential exterior surface covers by its circumferential exterior surface being sheathed on body completely, makes directly to see body by the outer surface of the withstand voltage pipe close of this cable duct bank.The external diameter of seal ring 1 and the internal diameter of comb match, place, the medial axis plane of its annular and the axis of body perpendicular.The outer surface that sealing ring 1 contacts with comb inwall has the ridge design that many increase the annular of frictional force between itself and the inwall of comb.
Axially locating assembly is for limiting the relative position at body two ends in its axial direction.Various structures can be adopted to realize above-mentioned functions, and such as, axially locating assembly comprises the end casing 2 at the axial two ends being divided into body for a pair and several are fixedly connected on fixed connecting piece between two end casings 2.Concrete, end casing 2 is in the circle identical with the cross section of body, and the glass fibre reinforced plastic material of hard can be adopted to make, and two end casings 2 make the circumferential exterior surface of body be positioned at therebetween.Fixed connecting piece be through injection pot connect pair of end cover plate 2 standing screw 3, to match the set screw nut 4 merging and be positioned at outside end casing 2 with standing screw 3.In the present embodiment, four are adopted to be uniformly distributed in standing screw 3 on end casing 2 and eight set screw nuts 4, each standing screw 3 is equipped with two set screw nuts 4, and these two set screw nuts 4 to lay respectively at end casing 2 outside two end casings 2 and body is clamping is integrated.
Injection pot needs to have coupled logical material feeding port, and this material feeding port can be arranged on the middle position of an end casing 2, adopts the filling tube 5 that an axis along body is arranged.Material feeding port place needs to have the valve 6 controlling it and open or close, and this valve 6 is arranged on filling tube 5.
Limit assembly is arranged on an end casing 2, and it is installed on position in comb for limiting the withstand voltage pipe close of cable duct bank.In the present embodiment, limit assembly comprises two symmetries and is installed on position-limited lever 7 on end casing 2, and this position-limited lever 7 is L-shaped.For simplicity, one end of position-limited lever 7 is directly connected in the end of two symmetrical standing screws 3 and is molded as one with standing screw 3, make a part that position-limited lever 7 is connected with end casing 2 and end casing 2 perpendicular, another part then parallels with end casing 2.Have its other end in the part that position-limited lever 7 parallels with end casing 2, this end protrudes from the external diameter of seal ring 1.
Operating component is used for the connection instrument when pipe close withstand voltage by setting tool installing cables comb.In the present embodiment, operating component comprises the installation screw rod 8 for being connected with setting tool by screw thread be arranged on end casing 2, and in order to simplified structure, this installation screw rod 8 directly can be integrated in the end of two standing screws 3 not being provided with limit assembly.
Above-mentioned filling tube 5, limit assembly and mounting assembly are positioned on the end casing 2 of the same side, and when the withstand voltage pipe close of this cable duct bank is installed in the end of comb, this end casing 2 with limit assembly and mounting assembly need towards this end.First, by setting tool, withstand voltage for cable duct bank pipe close is pushed the end of comb, finally makes position-limited lever 7 be stuck in the edge of comb end, prevent the withstand voltage pipe close of cable duct bank to push position excessively dark.Then in injection pot, fill in filler by material feeding port and force body to its circumferential expansion, body forces seal ring 1 also to extend out further, thus seal ring 1 is closely pressed on the inwall of comb.Highly preferred scheme is, in injection pot, filling in one by compressor can starch and make to reach certain pressure intensity in injection pot by the dilatable special cement of volume after solidification.Along with solidifying of cement slurry, its volume expands gradually, thus forces body and seal ring 1 synchronously to expand to the inwall of comb.Fill in the process of filler above-mentioned, axially locating assembly can prevent body from expanding in its axial direction, and only expands in its circumferential direction.When the withstand voltage pipe close of this cable duct bank removed by needs, first by screw thread setting tool is fixed on and installs on screw rod 8, then pull setting tool can realize the dismounting of the withstand voltage pipe close of cable duct bank.
This cable duct bank is withstand voltage, and pipe close can realize and the fitting tightly of comb inwall, thus by cable duct bank reliably shutoff, and larger pressure can be born, reach a series of functions such as waterproof, fire prevention, anti-mud, anti-foreign material.It can in 2-3 Reusability, aging speed is comparatively slow, and total service life can reach more than 20 years.Meanwhile, it is convenient to dismounting, for later stage cable laying and maintenance are provided convenience.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
