Description
[technical field]
This utility model relates to the technical field of the technical field of power cable auxiliary equipment, particularly power cable protecting pipe.
[background technology]
Power cable needs to be laid on underground, in order to improve the life-span of cable, slows down the aging of insulation sheath, often needs to intercept cable with external environment condition, uses protection pipe to seal cable, prevents the external environment condition infringement to cable.
If it is long that power cable protecting pipe is arranged, needing to expend bigger pull strength when laying cable the most wherein, and protect the cost of transportation of pipe to improve, splicing so typically power cable protecting pipe being set to segmentation structure.But general connecting method is bolted, easily causing loosening, meanwhile, protection pipe is colded and heat succeed each other by external environment condition when of impact, and the expansion of himself and contraction distortion can produce impact to junction.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of CPVC power cable protecting pipe, it is possible to make between the connection end of protection pipe contact closely, simultaneously it can be avoided that the thermal deformation impact on protection composite pipe tightness.
For achieving the above object, the utility model proposes a kind of CPVC power cable protecting pipe, including main protection pipe, connecting tube, the first magnet ring, the second magnet ring with pick up magnetic coil；Described main protection pipe two ends are provided with the threaded ends of band bent angle, and the two ends of described connecting tube are provided with threaded nut cap, and described connecting tube two ends are connected by the threaded ends of the described main protection pipe of nut cap and two respectively；The end of described nut cap is provided with described first magnet ring, and described main protection tube end is provided with the second magnet ring, and while nut cap is threadeded with threaded ends, described first magnet ring and the second magnet ring magnetic connect；The bottom of described threaded ends is provided with picks up magnetic coil, and the magnetic induction line between described first magnet ring and the second magnet ring picks up magnetic coil through described；The described magnetic coil that picks up is connected on a signal amplifier being arranged on main protection inside pipe wall by lead-in wire, and described signal amplifier and a controller wire being arranged on remote terminal connect.
As preferably, the described number of turn picking up magnetic coil is a circle or multiturn.
The beneficial effects of the utility model: this utility model is by being arranged to the two ends structure with bent angle by the main protection pipe of power cable protecting pipe; make main protection pipe sealing will be caused affect the connection end of two sections of main protection pipes because of the expanding with heat and contract with cold impact of external environment condition upon connection, it is to avoid the sealing of power cable protection environment is destroyed；Retrained by the magnetic force between the first magnet ring and the second magnet ring set by the nut cap in connecting tube and main protection tube end; on the one hand the fastness of connection is added; on the other hand as the detection signal of low-power consumption; when annexation is destroyed; by picking up the magnetic coil detection to magnetic dispersion signal; make to protect composite pipe tightness energy of rupture to access to feed back rapidly and accurately, thus power cable is protected the most reliably.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.

[detailed description of the invention]
Refering to Fig. 1～Fig. 5, this utility model one CPVC power cable protecting pipe, including main protection pipe 1, connecting tube the 2, first magnet ring the 6, second magnet ring 4 with pick up magnetic coil 7；Described main protection pipe 1 two ends are provided with the threaded ends 3 of band bent angle, and the two ends of described connecting tube 2 are provided with threaded nut cap 5, and described connecting tube 2 two ends are connected with the threaded ends 3 of two described main protection pipes 1 by nut cap 5 respectively；The end of described nut cap 5 is provided with described first magnet ring 6, and described main protection pipe 1 end is provided with the second magnet ring 4, and while nut cap 5 is threadeded with threaded ends 3, described first magnet ring 6 and the second magnet ring 4 magnetic connect；The bottom of described threaded ends 3 is provided with picks up magnetic coil 7, and the magnetic induction line between described first magnet ring 6 and the second magnet ring 4 picks up magnetic coil 7 through described；The described magnetic coil 7 that picks up is connected on a signal amplifier 8 being arranged on main protection pipe 1 inwall by lead-in wire, and described signal amplifier 8 is connected with controller 9 wire being arranged on remote terminal.The described number of turn picking up magnetic coil 7 is a circle or multiturn, and the number of turn is the most, then induced current is the biggest.
Utility model works process:
This utility model CPVC power cable protecting pipe, before power cable is carried out provided underground, is enclosed within described CPVC power cable protecting pipe on cable, jointly imbeds underground with cable；nullCPVC power cable protecting pipe is in fragmentation state before the use，Needs assemble，The two ends of its one end with connecting tube 2 are docked by two sections of main protection pipes 1 respectively mutually，Ride connecting tube 2 and threaded ends 3 by nut cap 5 simultaneously，Main protection pipe 1 is fixed with connecting tube 2，Now，The second magnet ring 4 being positioned on main protection pipe 1 produces magnetic force with the first magnet ring 6 being positioned on nut cap 5 because heteropole is attracting and retrains，Strengthen main protection pipe 1 and the connectivity robustness of connecting tube 2，Simultaneously，Magnetic field intensity between first magnet ring 6 and the second magnet ring 4 is in steady state when the two not displacement to axial，Therefore there is relative displacement when junction，When i.e. the sealed environment of cable occurs to destroy，Instantaneous faradic current will be produced in picking up magnetic coil 7，This current signal is by being transferred at controller 9 after the amplification of signal amplifier 8，Make staff can find the leakage of CPVC power cable protecting pipe in time；Owing to being provided with bent angle at the two ends of main protection pipe 1; so when the CPVC power cable protecting pipe generation temperature distortion connected; the stress that thermal deformation produces will be concentrated mainly on the corner of main protection pipe 1; bent angle deforms will snubber thermal stress, it is to avoid the sealing of the junction between main protection pipe 1 and connecting tube 2 is destroyed.
This utility model; by the main protection pipe of power cable protecting pipe is arranged to the two ends structure with bent angle; make main protection pipe sealing will be caused affect the connection end of two sections of main protection pipes because of the expanding with heat and contract with cold impact of external environment condition upon connection, it is to avoid the sealing of power cable protection environment is destroyed；Retrained by the magnetic force between the first magnet ring and the second magnet ring set by the nut cap in connecting tube and main protection tube end; on the one hand the fastness of connection is added; on the other hand as the detection signal of low-power consumption; when annexation is destroyed; by picking up the magnetic coil detection to magnetic dispersion signal; make to protect composite pipe tightness energy of rupture to access to feed back rapidly and accurately, thus power cable is protected the most reliably.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after this utility model simple transformation is belonged to protection domain of the present utility model.
