Description

Technical Field

[0001] The utility model relates to the technical field of detection cables, in particular to a water leakage detection cable capable of preventing false alarms. Background Art

[0002] Water leakage can often occur in any building, and once it occurs, it may cause significant economic losses. In the era of popular network applications, water leakage detection in data center computer rooms is particularly important. Strong and weak wires are generally arranged under the static floor. It is not easy to find water leakage in the data center computer room due to air conditioning or fire protection pipes. If water leakage cannot be detected and eliminated in time, it may cause major safety accidents such as line short circuit fire, equipment immersion damage, etc.

[0003] A Chinese patent with announcement number CN201387735Y discloses a water leakage sensing detection cable, including a sensing wire, characterized in that it also includes an insulating frame, the outer circumference of the insulating frame has a plurality of grooves evenly distributed in the circumferential direction and extending in a spiral shape along the length direction, the sensing wire is placed in the groove, and is spirally twisted at equal distances around the plastic frame as the center, forming a multi-twisted wire shape centered on the frame.

[0004] The above-mentioned disclosed patent still has the following technical defects: during detection, water needs to submerge both detection copper wires. When the water level is low, it cannot submerge the entire cable, thereby failing to trigger the alarm. The cable is spirally arranged, which increases the use of wires and leads to increased costs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the background technology and proposes a water leakage detection cable which can prevent false alarms.

[0006] The technical solution of the utility model is a water leakage detection cable that prevents false alarms, comprising:

[0007] The insulating frame is a flat structure, and two induction wire grooves are provided on the insulating frame along its length direction, and the two induction wire grooves are arranged on the same side of the insulating frame;

[0008] Two induction lines, the two induction lines are placed in the induction line slots on both sides;

[0009] Two electric wires, both of which are arranged on the inner side of the insulating frame;

[0010] The controller, one end of the electric wire and the induction wire are all connected to the controller;

[0011] The other ends of the sensing wires of the electrical wires are connected to the terminators.

[0012] Preferably, the outer side of the sensing wire is coated with a polymer conductive material.

[0013] Preferably, a plurality of transverse reinforcing wires and a plurality of longitudinal reinforcing wires are arranged on the inner side of the insulating frame, and the plurality of transverse reinforcing wires and the plurality of longitudinal reinforcing wires together form a grid structure.

[0014] Preferably, the depth of the sensing wire groove is greater than the diameter of the sensing wire.

[0015] Preferably, a plurality of binding wires for fixing the sensing wires are arranged side by side in the sensing wire slot.

[0016] Preferably, the outer surface of the insulating frame is wrapped with a waterproof membrane.

[0017] Compared with the prior art, the utility model has the following beneficial technical effects: the cable is arranged as a flat structure, and one end of the sensing wire trough is placed at the bottom, so that a lower water level can be detected, the detection range is wider, and less consumables and low manufacturing cost are required.

[0022] Embodiment 1

[0023] like Figure 1-Figure 4 As shown, the present embodiment provides a water leakage detection cable for preventing false alarms, comprising an insulating frame 1, a controller, a terminator, two sensing wires 3 and two electric wires 2.

[0024] The insulating frame 1 is a flat structure, and the outer surface of the insulating frame 1 is wrapped with a waterproof film. Two induction wire grooves 101 are provided on the insulating frame 1 along its length direction, and the two induction wire grooves 101 are arranged on the same side of the insulating frame 1; two induction wires 3 are respectively placed in the induction wire grooves 101 on both sides, and the depth of the induction wire grooves 101 is greater than the diameter of the induction wire 3. Such an arrangement can prevent the induction wire 3 from extending to the outside of the induction wire grooves 101, and prevent false alarms caused by contact between metal objects and the two induction wires 3. A plurality of binding wires 6 for fixing the induction wires 3 are arranged side by side in the induction wire grooves 101; two electric wires 2 are arranged on the inner side of the insulating frame 1; one end of the electric wire 2 and the induction wire 3 are connected to the controller; the other ends of the electric wire 2 and the induction wire 3 are connected to the terminator.

[0025] In this embodiment, when performing detection, the controller is set to emit a constant current, detect the return circuit, determine whether there is a water leakage point and calculate the position of the water leakage point. The controller emits a constant current to the sensing line 3 and the wire 2. The setting of the wire 2 is used to detect the total length of the cable. When a water leakage occurs at a certain point of the sensing line, since water is a conductor, the water immerses the two sensing lines 3. At this time, the two sensing lines will be short-circuited, and the conductivity of the water will cause the resistance value of this part to change. Then, according to the proportional relationship between the resistance and the conductor length, by monitoring the change in resistance, it can be determined whether there is a water leakage. The controller can calculate the relative position of the water leakage based on the detected voltage, resistance, and current parameters (the above is the detection principle for locating the leakage rope, which has been disclosed in the prior art documents, so it will not be repeated); the cable is set to a flat structure, and one end of the sensing line slot 101 is placed at the bottom, so that a lower water level can be detected, the detection range is wider, and there is no need to wind the wire in a spiral structure, saving the use of wire.

[0026] Embodiment 2

[0027] This embodiment proposes a false alarm-proof water leakage detection cable. Compared with the first embodiment, in this embodiment, the outer side of the sensing line 3 is coated with a polymer conductive material, and the polymer conductive material is provided to prevent the sensing line 3 from rusting.

[0028] Embodiment 3

[0029] like Figure 2 As shown, the present embodiment proposes a false alarm-proof water leakage detection cable. Compared with the first embodiment, in the present embodiment, a plurality of transverse reinforcing wires 4 and a plurality of longitudinal reinforcing wires 5 are arranged on the inner side of the insulating skeleton 1. The plurality of transverse reinforcing wires 4 and the plurality of longitudinal reinforcing wires 5 together form a grid structure. The structural strength of the insulating skeleton 1 can be enhanced by arranging the plurality of transverse reinforcing wires 4 and the plurality of longitudinal reinforcing wires 5.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
