Description

Region-type water leakage detection line

Technical field

This utility model relates to water leakage detection line, particularly relates to the waterproof oxidation resistant region formula water leakage detection line of a kind of convenient extension.

Background technology

When whether signal piping, ground or relevant place leak, two metal electrodes of general employing or two exposed wires are arranged on detection place as sensing apparatus.When having liquid to leak and flowing in detection range, short circuit between two metallic conductors can be made, thus trigger warning.

This cable leaked for detection is referred to as water leakage detection line by prior art, and in order to constitute complete water-leakage detecting system, user is according to field demand, it usually needs water leakage detection line two ends are welded male and female joint, for dismounting and extension.But this mode not only increases material cost and human cost, also need to focus more in joint waterproofing performance simultaneously, virtually the acceptance rate of product is had a greatly reduced quality.

Summary of the invention

This utility model is in order to solve existing problem, a kind of region-type water leakage detection line is proposed, including the wire body leaked for detection, described wire body wherein one end is welded by one end of the first waterproof moulding and one or two core connecting line, and the other end is sealed by the second waterproof moulding.

Being respectively arranged at two ends with of described first waterproof moulding is available for wire body and the incoming line of two core connecting lines access, the both sides of each incoming line are provided with the first trough and second trough of relative L-shaped, be respectively equipped with and be available for wire body and the pad of two core connecting lines connection between two the first troughs and between two the second troughs.

Described wire body includes: a flexible insulation cable, two helical grooves arranged on the outer wall of described insulation cable along described insulation cable axial direction, lays respectively at the first heart yearn that is in two helical grooves and that wrapped up conducting polymer and the second heart yearn.

Described wire body connects prolongation cable or harvester by line nose.

Described first, second waterproof moulding is cylindrical.

Compared with prior art, the beneficial effects of the utility model: this utility model allows two core connecting lines connect the one end of the wire body detecting line, thus carry out the field demand that flexible adaptation is different, wire body install after just without again dismantling welding, two core connecting lines only need to be changed when having Different field demand, compared with the wire body of detection line, two core connecting lines are cheap plain conductor, the loss destruction of wire body brought during Rewelding dismounting wire body for adapting to Different field demand is prevented by this setting, user can extend two core connecting lines voluntarily, extensibility is strong, reduce the cost of extension wire body.The other end of the wire body of detection line connects power supply after being encapsulated by plastic part again, and water resistance is more preferable.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the profile of the waterproof moulding of this utility model first.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is further illustrated.

As shown in Figure 1, the region-type water leakage detection line that an embodiment of the present utility model proposes, including the wire body 4 leaked for detection, wire body 4 includes an insulation cable being fabricated from a flexible material, along this insulation cable axial direction, it is provided with two helical grooves around this insulation cable outer wall, in two grooves, placed the first heart yearn and the second heart yearn having wrapped up conducting polymer respectively.

Wire body 4 is respectively arranged at two ends with the first waterproof moulding 3 and the second waterproof moulding 5, first, second waterproof moulding is cylinder, one end of wire body 4 is connected with one or two core connecting line 2 by the first waterproof moulding 3, packaged after just without dismounting change, connect harvester by two core connecting lines 2.Two core connecting lines 2 can also wiring nose 1, be then directly connected to the binding post of harvester by line nose 1.During use, connecting harvester by two core connecting lines, harvester applies voltage, then by the wire body of water leakage detection line, the region that leaks is carried out leak water detdction.

Two core connecting lines 2 use plain conductor, have two strands, are defaulted as 2 meters long, when length is inadequate, prolongation cable, or hookup wire nose 1 can be connected at the end insulating tape of two core connecting lines, then connect prolongation cable by line nose 1, connect harvester the most again.Concrete, cable will be extended and insert line nose, process with Crimping Pliers line ball, and extend cable and be i.e. connected with two core connecting lines and secure, easy to operate, antioxidation.Plain conductor low cost, simultaneously for adapting to the wire of different internal resistance specifications on market, reduces because of the excessive impact on detection line conductive core line resistance of connecting line resistance, when designing harvester, increases constant-current source, reduce pressure drop；Detection line conductive core line resistance is increased when producing detection line.The other end of wire body 4 is encapsulated by the second waterproof moulding 5, and water resistance is more preferable.

As in figure 2 it is shown, the first waterproof moulding 3 profile is cylindrical, its two ends are provided with incoming line, and the first heart yearn 41 and second heart yearn 42 of wire body 4 enter from Fig. 2 right-hand member, and two strands of wires 21,22 of two core connecting lines 2 enter from left end.The both sides of each incoming line are equipped with relative L-shaped trough, wherein two troughs in top are the first trough 61,63, two troughs in lower section are the second trough 62,64, it is respectively equipped with pad 7 between two the first troughs and between two the second troughs, first heart yearn 41 of wire body 4 is through the first trough 63, being soldered to pad 7, the wire 21 of two core connecting lines 2 connects with the first heart yearn through the first trough 61 to pad 7.The second same heart yearn 42 is through the second trough 62, and the second heart yearn 42 connects at the second trough 54 pad between which.The setting of L-shaped trough can stretching resistance, prevent from extraneous applying excessive pulling force and causing wire body to disconnect with the weld of two core connecting lines.First waterproof moulding injection sealed loads wire body and the weld of two core connecting lines simultaneously, has waterproof anti-oxidation effect.

The two ends of detection line wire body are packaged by this utility model by the first waterproof moulding and the second waterproof moulding, water resistance is more preferable, the two core connecting lines with wire body waterproof enclosure can be with connecting line nose simultaneously, line nose can be inserted directly into the terminals of harvester, very convenient attractive in appearance, and when user wants to extend two core connecting lines, the one end extending cable only need to be inserted line nose, again with Crimping Pliers line ball, simple to operation.In conjunction with global design, this utility model extensibility is strong, greatly reduces material cost and human cost, has excellent waterproof antioxygenic property simultaneously, extend the service life of water leakage detection line the most to a certain extent.

Above specific embodiment is only in order to illustrate design of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, within these deformation and change are included in protection domain of the present utility model.
