Description
【Technical field】
The present invention relates to the technical fields of cable protection pipe, the especially technical field of cable protection tube connector.
【Background technology】
Power cable has important strategic importance, needs the job stability of its all the period of time of strict guarantee.However due to
Bad environments reason often causes the breakage problem of power cable, is required for outside it so being laid with power cable now
It is set with power cable protecting pipe.
Power cable protecting pipe needs the leakproofness for having certain, and otherwise power cable still has uncontrollable potential damage
Evil is dangerous, and considers construction transportation reasons, and present power cable protecting pipe is that the mode of segmented splicing is used, institute
Become particularly important with the connector between two sections of cable protection pipes, needs to carry out sufficient R ＆ D design.
【Invention content】
The purpose of the present invention is just to provide for a kind of connector of cable protection pipe, can make connected two sections of cables
Protection pipe is completely embedded, and can send out alarm in time when gap occurs in junction, and reminding technology personnel rebuild.
To achieve the above object, the present invention proposes a kind of connector of cable protection pipe, including end-connector, centre
Connecting tube, ring-shaped clip pedestal and piezoelectric ceramic piece；One end of the end-connector and the port threads of cable protection pipe connect
It connects, the other end of end-connector is provided with end flange, and the intermediate connection tube is provided at both ends with center flange, two sections of electricity
The end-connector connected on cable protection pipe docks end flange with the center flange positioned at intermediate connection tube both ends, and
It is fixedly connected by bolt；The ring-shaped clip pedestal inlay card is in the end flange and center flange of docking, the pressure
Electroceramics piece is embedded in the ring-shaped clip pedestal, and the polarization direction of piezoelectric ceramic piece is parallel with the axis of intermediate connection tube；
Electrode plate is provided on the plane of polarization up and down of the piezoelectric ceramic piece, electrode plate is connected by conducting wire with external signal picker
It connects.
Beneficial effects of the present invention：The present invention will be by that will use three-stage connector, end-connector and cable protection pipe
Threaded connection is easily installed, and after being bolted between intermediate connection tube and end-connector, being completely embedded property passes through
The piezoelectric ceramic piece being embedded in ring-shaped clip pedestal carries out highly sensitive detection feedback, may be implemented to be bolted the tight of section
Close type all the period of time detection, had both used bolted convenience, and had in turn ensured the wireline environment that cable protection pipe is protected
Compactness.
The feature and advantage of the present invention will be described in detail by embodiment combination attached drawing.
【Description of the drawings】
Fig. 1 is the main view sectional view of the connector of cable protection pipe of the present invention；
Fig. 2 is the sectional view of end connector of the present invention；
Fig. 3 is the sectional view of intermediate connection tube in the present invention.
In figure：1- cable protection pipes, 2- end-connectors, 3- ring-shaped clips pedestal, 4- piezoelectric ceramic pieces, the connection of the centres 5-
Pipe, 6- bolts, 201- end flanges, 501- center flanges.
【Specific implementation mode】
Refering to fig. 1, Fig. 2 and Fig. 3, the connector of cable protection pipe of the present invention, including end-connector 2, intermediate connection tube
5, ring-shaped clip pedestal 3 and piezoelectric ceramic piece 4；One end of the end-connector 2 connects with the port threads of cable protection pipe 1
It connects, the other end of end-connector 2 is provided with end flange 201, and the intermediate connection tube 5 is provided at both ends with center flange
501, the end-connector 2 connected on two sections of cable protection pipes 1 by end flange 201 be located at 5 both ends of intermediate connection tube
Center flange 501 dock, and be fixedly connected by bolt 6；End method of 3 inlay card of ring-shaped clip pedestal in docking
On orchid 201 and center flange 501, the piezoelectric ceramic piece 4 is embedded in the ring-shaped clip pedestal 3, the pole of piezoelectric ceramic piece 4
It is parallel with the axis of intermediate connection tube 5 to change direction；It is provided with electrode plate, electrode on the plane of polarization up and down of the piezoelectric ceramic piece 4
Plate is connected by conducting wire with external signal picker.
The course of work of the present invention：
The connector of cable protection pipe of the present invention during the work time, when between end-connector 2 and intermediate connection tube 5
When junction is got loose, end flange 201 and center flange 501 pull ring-shaped clip pedestal 3 that piezoelectric ceramic piece 4 is driven to deform
It stretches, to generate piezoelectric effect, the two poles of the earth end face of piezoelectric ceramic piece generates charge, is sent to electric signal outside by electrode plate
The signal picker in portion, to send out alarm.
The present invention, by the way that three-stage connector, end-connector will be used to be threadedly coupled and be easily installed with cable protection pipe,
And after being bolted between intermediate connection tube and end-connector, being completely embedded property is by being embedded in ring-shaped clip pedestal
Interior piezoelectric ceramic piece carries out highly sensitive detection feedback, the tight type all the period of time detection for being bolted section may be implemented, both
Bolted convenience is used, in turn ensures the compactness for the wireline environment that cable protection pipe is protected.
Above-described embodiment is the description of the invention, is not limitation of the invention, it is any to simple transformation of the present invention after
Scheme all belong to the scope of protection of the present invention.
