Description
Technical field
The present invention relates to a kind of jacket structures, and in particular to a kind of warning warning power cable oversheath.
Background technique
Cable is usually the cable of similar rope as several or made of several groups of wire strandings, between every group of conducting wire mutually absolutely
Edge, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Multi rack is located at aerial or is mounted in ground
Under, it is water-bed, be used for telecommunication or power Transmission, but due to the continuous development of society, it is unavoidable in the way of development construction
Ground is dug, but when digging ground, the example for digging power-off cable can be found everywhere, and once cable needs whole by broken skin or fracture
Route must all be replaced, and can not repair, and impact very big, and not only labor intensive, material resources, and its problem are extremely difficult is sent out
It is existing, cause working efficiency straight line to decline, permanent one, the protection for cable, and when being laid with cable, it can not for gravel
There are a preferable barrier systems, it is known that gravel is the crust for being highly vulnerable to breakage cable, cable sheath breakage is to exist very
Big security risk, but such problems, none effective measures or scheme always.
Summary of the invention
The purpose of the present invention is to provide a kind of warnings to alert power cable oversheath, and can protect cable sheath will not be by
Gravel destroys, while the most important is to prevent to be destroyed by external force on the way in construction, can be straight when by certain external force
Coloured smog is discharged in contact hair cable jacket, to achieve the purpose that remind staff, it is made not continue to apply external force,
Damage location can be positioned simultaneously, the cable jacket of pipe joint type can be replaced targetedly, extremely convenient.
A kind of warning warning power cable oversheath, including sleeve, net cylinder；It is characterized in that the sleeve is divided into internal layer, outer
Two layers of layer；It is equipped with net cylinder in the middle part of the internal layer, and is filled with buffer body in its complementary space of internal layer；It is filled in the outer layer
There is compressed gas；One end of the sleeve is equipped with groove, is equipped with concave ring in groove inner sidewall；The other end of the sleeve is equipped with convex
Platform, the leakproofness of cable jacket can be increased by the cooperation of concave ring and bulge loop by being equipped with bulge loop in the lateral wall of boss；Institute
Sleeve is stated equipped at least one, the boss on each sleeve can complementary abutting joint with the groove on other sleeves；The sleeve
Axial direction on be open loop shape, cable is tucked into sleeve by the opening on axial direction；The opening both ends are equipped with interface,
The also uniform through-hole being equipped with convenient for permanent opening on interface, through-hole both ends are symmetrically equipped with through-hole ear, pacify in through-hole
Equipped with native font bolt；The sleeve both side ends are equipped with the valve inside for filling gas.
Preferably, buffering adhesive can be selected in the buffer body material.
Preferably, orchil is filled in the compressed gas, and compressed gas is inert gas.
Preferably, rubber gasket is equipped between the opening.
Preferably, steel wire or Carbon Fibre Textile cylinder can be selected in the net cylinder.
Preferably, chlorosulfonated polyethylene, material resistant to chemical media burn into ozone-resistant oxidation can be selected in the sleeve material
And the performances such as resistance to oil corrosion, fire-retardant are prominent, also have the change of anti-times, heat-resisting, anti-ionizing radiation, low temperature resistant, anti scuffing and electrical isolation
Property and excellent mechanical performance, and itself also have certain elasticity.
Preferably, the sleeve is equipped with different length specification, to meet different demands.
The beneficial effects of the present invention are accidental injury of the external force for cable run can be effectively prevented, constructor is reminded in time
The position of member's cable, the effective protection integrality of cable, by coloured smog, to achieve the purpose that remind staff,
Make it not continue to apply external force, while the damage location of sleeve wall can be quickly found out, the mounting means of pipe joint type can have
Targetedly it is quickly replaced, it is extremely convenient.

Specific embodiment
As shown, a kind of warning alerts power cable oversheath, including sleeve 1, net cylinder 2；It is characterized in that the sleeve 1
It is divided into internal layer 1-1, outer layer 1-2 two layers；It is equipped with net cylinder in the middle part of the internal layer 1-1, and is filled in its complementary space of internal layer 1-1
Buffer body selects buffering adhesive and net cylinder 2 that internal layer 1-1 is allow to have certain antagonism to external force, makes 8 crust of cable from artificial
External force it is caused to accidentally injure；The gas filled with dyestuff filled with inertia compression in the outer layer 1-2, using being infected with red
Inert gas can be eye-catching prompting construction personnel cable 8 position and avoid or stop in time；One end of the sleeve 1
Equipped with groove 7, concave ring is equipped in 7 inner sidewall of groove；The other end of the sleeve 1 is equipped with boss 6, sets in the lateral wall of boss 6
There is bulge loop, by the cooperation of concave ring and bulge loop, the leakproofness of cable jacket can be increased；The sleeve 1 is equipped at least one,
Boss 6 on each sleeve 1 can complementary abutting joint with the groove 7 on other sleeves 1；It is on the axial direction of the sleeve 1
Open loop shape, cable 8 are tucked into sleeve 1 by the opening in axial direction；The opening both ends are equipped with interface 3, in interface 3
The upper also uniform through-hole 4 being equipped with convenient for permanent opening, 4 both ends of through-hole are symmetrically equipped with through-hole ear, are equipped with soil in through-hole 4
Font bolt；The 1 amount side end of sleeve is equipped with the valve inside 5 for filling gas；It is close that rubber is additionally provided between the opening
Packing prevents gravel from being involved in 1 inner wall of sleeve and the generation friction of 8 crust of cable, damages to 8 crust of cable；The sleeve 1
Chlorosulfonated polyethylene can be selected in material, and material resistant to chemical media burn into ozone-resistant oxidation and the performances such as resistance to oil corrosion, fire-retardant are prominent
Out, also there is anti-times to become, is heat-resisting, anti-ionizing radiation, low temperature resistant, anti scuffing and electrical insulating property and excellent mechanical performance, and
Body also has certain elasticity；And by the sleeve 1 of setting different length specification, to meet different demands, applicability is wider.
Sleeve 1：When in use, sleeve 1 is broken into two with one's hands from opening, then cable 8 is tucked into sleeve 1, each sleeve 1
It is docked by groove 7 with the complementary fit of boss 6, can form the oversheath that an entirety is wrapped in the periphery of cable 8, in sheath
Layer 1-1 forms the protective layer that can resist external force by buffering adhesive and braided steel wire net, passes through filling in sheath outer layer 1-2
On the one hand colored gas can play the role of resisting external force, on the other hand can be after external force destroys outer layer 1-2, can
Timely the dyeing gas by inside filling releases, and reminds construction personnel already close to cable 8 is destroyed, does not continue to apply
External force guarantees that cable 8 will not be destroyed.
