Abstract
The utility model relates to a blocked position detector for a pipeline. The blocked position detector comprises an alarm device, a cable and a magnetic induction switch which are sequentially connected end to end, wherein the magnetic induction switch is correspondingly and electrically connected with two leads in the cable; and the magnetic induction switch comprises a reed switch, wherein the reed switch is externally sheathed with a cylindrical spring, and the rear end of the cylindrical spring and the front end of an insulating bush of the cable are assembled in an anti-dropping mode. The blocked position detector adopts the cylindrical spring as the shell of a probe of the magnetic induction switch. In the operation, the probe is bent along a bent pipeline, and the rear end of the probe and the cable are driven to move forwards, so that the shell of the blocked position detector is more convenient to use as compared with a hard shell. Moreover, the cylindrical spring and the cable are connected in a detachable mode, and are different from the former integral design of the cylindrical spring and the cable, so that only the probe is required to be exchanged when the probe is damaged.
Description
Technical field
The utility model relates to a kind of pipeline blockage positional detecting device.
Background technique
Application number is that 201020243238.4 Chinese patent file " pipeline blockage positional detecting device " has disclosed a kind of prober that is used to survey blocking position in the hidden pipe.Document goes out: building is when construction; Need in advance upper and lower conduit, electric pipeline etc. to be embedded in the body of wall in advance, because top pipe laying spare route is very long, if pipeline blockage takes place; Can give under the executing in later stage and make troubles; Search the obstruction point and not only will destroy the multiaspect body of wall, also can waste a large amount of manpowers, slow down construction speed.In order to save manpower, this document provides a kind of autodetector, when indoor pre-buried pipeline takes place to stop up; The twin-core poling cable that will have the magnetic switch sound end from the mouth of pipe is sent into, and through broadcasting cable probe is moved forward along pipeline, when popping one's head in forward; Promptly reach the obstruction point, at this moment, the hand-holdable detection magnet of operator; Roughly route by pipe laying moves that (if unclear roughly route needs to survey magnet and closely joins with probe and close, probe makes a move; Magnet can lean out the roughly trend of pre-buried pipeline with a step), in the time of near detection magnet moves to probe; Magnetic field makes the normal make contact that rises of magnetic switch probe, and the position warning device sends signal, and can navigating to blocking position haply, 1Ocm sees the zone of power.Blocking position can excavate body of wall and pipeline after confirming targetedly, has avoided construction in blind day, has saved human and material resources.
The magnetic switch probe that mainly comprises twin-core cable and double wired conductor cable end portion of said apparatus, the magnetic switch probe is connected to power supply and warning part, the i.e. warning device of its rear end through the twin-core cable.Usually the magnetic switch probe is wholely set with the twin-core cable, and the magnetic switch probe segment is harder, is difficult for bending at the pipe bending place, causes and uses inconvenience.Magnetic switch is selected dry reed-pipe usually for use, and the situation of damage in use often appears in dry reed-pipe, in case damage, must change whole twin-core cable and magnetic switch probe, has caused very big waste like this.
The model utility content
The purpose of the utility model provides a kind of pipeline blockage positional detecting device, in order to solve the existing awkward problem of prober.
For realizing above-mentioned purpose; The scheme of the utility model is: a kind of pipeline blockage positional detecting device; Being joined before and after successively by warning device, cable and magnetic switch constitutes, the corresponding electrical connection of two leads in magnetic switch and the cable, and said magnetic switch comprises dry reed-pipe; Dry reed-pipe is arranged with a cylindrical spring outward, the front end anticreep assembling of the rear end of cylindrical spring and the insulating bush of cable.
Adopt the shell of cylindrical spring as the magnetic switch probe, in operation, probe can drive probe rear end and cable and move forward along the bending tube curved way, and it is convenient more to use than hard shell.And because cylindrical spring and cable removably connect, no longer be the design of former one, get final product so when probe damages, only need change probe.
First lead of said cable is electrically connected with an end of said dry reed-pipe, and second lead is electrically connected with the other end of dry reed-pipe through said cylindrical spring.The front end of the insulating bush of said cable is provided with a shell fragment that is electrically connected with said second lead, the front end interference fit of the rear end of cylindrical spring and the insulating bush of said cable.Said first lead is connected through an electric coupler with an end of said dry reed-pipe.Said electric coupler is Du Pont's pin type socket.Said cylindrical spring head is provided with a seeker with hemisphere type head.Be arranged with hard plastic tube on the said dry reed-pipe periphery.Said warning device is the radio alarming device, comprises and the radio alarming transmitter of the lead wired connection of cable, radio alarming receiver and the transmitting antenna that is used to receive the alarm signal of said radio alarming transmitter and carries out acoustooptic alarm; Said transmitting antenna is connected on the radio alarming transmitter, extends in the cable.
In the utility model, adopt the part of cylindrical spring as electric loop.Owing to damage is dry reed-pipe often, so adopted an electric coupler, only needs during dismounting dry reed-pipe is pulled down from electric coupler, only changes dry reed-pipe and gets final product.The cylindrical spring head is provided with the seeker with hemisphere type head, and the seeker front end is slick and sly, the break-in of convenient guiding cylindrical spring.The sheathed rigid insulation pipe of dry reed-pipe periphery prevents that dry reed-pipe is cracked, and dry reed-pipe is shielded.
