Description

A kind of novel water leakage detection line cable

Technical field

The utility model relates to the water leakage detection line cable, relates in particular to that a kind of quality is good, consumptive material is few, the novel water leakage detection line cable that cost is low.

Background technology

Along with information-based, intelligent fast development of building, at machine room, intelligent building, escalator, the storing storehouse, reference rooms etc. locate to be equipped with a large amount of electric power and communication cable.The window that these cables close on, water supply line, changes in temperature tracheae, air-conditioning drainage pipe etc. may seep water and leak, and these leak and can cause cable short circuit and signal transmission fault, cause equipment cisco unity malfunction even damage; Long-term ponding also can cause other serious accidents such as equipment corrosion.How accurately finding to leak the place, take maintenance measures in the shortest time, is the key that reduces the normal operation of device damage and assurance system.

Also there is the leakage inductive rope of cable type in the water leakage alarm system of at present domestic more existing simple probe-types.Probe-type also claims electric pole type, when near the electrode water being arranged, can trigger alarm signal, but there is following problem in it: single-point detects, and be difficult to multipoint positioning and detect, the easy oxidized corrosion of electrode, a spot of ponding in the face of land is difficult to detect.The leakage inductive rope of existing cable type is that the spiral twisting is arranged two leads and detected the line of induction that whether leaks on a skeleton, and the defective of its existence is: 1, lead is around the peripheral rotation of skeleton, and consumptive material is more; 2, line of induction appearance is an electric conducting material, when metallic conduit is laid, easily and metallic conduit touch, report by mistake.

The utility model content

The utility model is the problems referred to above that will solve prior art, proposes that a kind of quality is good, consumptive material is few, the novel widely water leakage detection line cable in the utilization field that cost is low.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of novel water leakage detection line cable of design, it comprises: the power line that lays side by side and the interconnection of tape insulation layer, be spirally wound on power line and interconnection the outside first line of induction and second line of induction.

Described first line of induction and second line of induction are set with protection network.

Described power line and interconnection overcoat protective layer; Described first line of induction and second line of induction twine along protective layer outer wall spiral.

Also be provided with a reinforcement with power line and interconnection parallel lay-up in the described protective layer.

The both sides that described protective layer is relative respectively are provided with a cloth line groove, and described cloth line groove distributes along protective layer outer wall spiral, and described first line of induction and second line of induction are inlaid in respectively in the cloth line groove.

The tail end of described power line connects the tail end of first line of induction, and the tail end of interconnection connects the tail end of second line of induction; The head end of power line, first line of induction, interconnection, second line of induction connects peripheral control unit.

Compared with prior art, the utility model economical with materials, safeguard protection performance height, rate of false alarm is low, can be close to any metal material pipe laying.Can be used in the various places of oozing, leaking that need to detect widely.

Description of drawings

Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:

Fig. 1 is the cross section view of the utility model preferred embodiment;

Fig. 2 is the cross section view of the utility model band cloth line groove;

Fig. 3 is the wiring schematic diagram of the utility model preferred embodiment.

Embodiment

Referring to Fig. 1, the disclosed novel water leakage detection line cable wrap of the utility model is drawn together: the power line that lays side by side 1 of tape insulation layer 3 and interconnection 2, be spirally wound on power line and interconnection the outside first line of induction 4 and second line of induction 5.Power line 1 and interconnection 2 are made of the ordinary copper electric wire; The line of

induction

4,5 is made of alloy material, and it has the resistance per unit length of customization, and resistance value is directly proportional with line length.Referring to Fig. 3, the tail end of described power line 1 connects the tail end of first line of induction 4, and the tail end of interconnection 2 connects the tail end of second line of induction 5; The head end of power line, first line of induction, interconnection, second line of induction connects peripheral control unit.There is water to leak when detecting cable somewhere 11, first line of induction and second line of induction are in the leakage point short circuit, controller is measured voltage, electric current and the resistance between each binding post D1, D2, D3, D4, calculates concrete leakage point according to the linear relationship of voltage, electric current and resistance.

Referring to the preferred embodiment shown in Fig. 1, described first line of induction 4 and second line of induction 5 are set with protection network 7.Protection network adopts insulated with material, but adopts network structure, and water and other liquid can flow on the line of induction by mesh.It is to be noted that protection network and protective layer can also adopt the material that can stand acid, alkali, oil corrosion, then the utility model just can detect the leakage of acid, alkali, oil, has widely at semiconductor factory, chemical plant, oil movement and storage center etc. and uses.The utility model can directly be close to any metal material pipe laying.Also can reduce rate of false alarm simultaneously, and can be because of ambient humidity higher or near have a small amount of condensed water to cause false alarm.Described power line and interconnection overcoat protective layer 6; Described first line of induction 4 and second line of induction 5 twine along protective layer 6 outer wall spirals.Protective layer 6 adopts fluorine material; power line 1 and interconnection 2 are laid in protective layer 6 centers ratio and are twisted in protective layer 6 outer walls and want economical with materials; and have better security protection performance and stronger anti-external interference ability; because of protective layer 6 is made of fluorine material, makes and detect cable and have better fire line and resistance to wear.Also be provided with a reinforcement 8 with power line 1 and interconnection 2 parallel lay-ups in the described protective layer 6, to strengthen detecting the intensity of cable.Reinforcement 8 and power line 1 and interconnection 2 distributions triangular in shape showed among Fig. 1,2, in other embodiments, reinforcement 8 is between power line 1 and the interconnection 2.
