Description

Technical Field

[0001] The utility model relates to the field of water accumulation monitoring of optical cable joint boxes, in particular to a water accumulation monitoring device for optical cable joint boxes. Background Art

[0002] The optical cable junction box is hung on the communication pole or cable trench, and is greatly affected by the climate environment. After years of exposure to the sun and rain, the sealed seal is prone to aging. Once water enters and accumulates, it will not only cause the metal fasteners in the shell to rust and cause the optical cable to fall out; or the optical fiber coating will be corroded by acidic sewage and easily break the fiber; more seriously, in winter, the water in the shell freezes, causing stress changes in the optical fiber, increasing the loss and significantly reducing the transmission quality. When the ice melts, the loss often returns to normal. Especially in the southern region, it often alternates between day and night, which brings us confusion in fault judgment. Therefore, providing a water monitoring device for optical cable junction boxes has become an urgent problem to be solved. Utility Model Content

[0030] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1 to Figure 2 , the first embodiment of the utility model:

[0032] A device for monitoring water accumulation in an optical cable joint box, comprising an optical cable box 1, a connecting plate 2, a welding plate 3, a water leakage sensing line 4 and a detection mechanism;

[0033] The connecting plate 2 is arranged in the optical cable box 1, and the interior of the optical cable box 1 is divided into a welding chamber and a detection chamber by the connecting plate 2;

[0034] The welding plate 3 is mounted on the connecting plate 2 and is located in the welding cavity;

[0035] The water leakage sensing line 4 is installed in the detection cavity, and one end of the water leakage sensing line 4 passes through the connecting plate 2 and is installed with a wire connector 6, and the wire connector 6 is installed on the surface of the box body 11 of the optical cable box 1;

[0036] The detection mechanism is electrically connected to the water leakage sensing line 4 through the wire connector 6, and is used to detect whether there is water accumulation in the optical cable box 1;

[0037] Wherein, the detection mechanism includes a power supply and an ammeter;

[0038] The ammeter is connected to the wire connector 6 via a wire interface;

[0039] The power supply is electrically connected to the ammeter and the water leakage sensing line 4 in sequence;

[0040] The water leakage sensing line 4 includes a first sensing line and a second sensing line, and the first sensing line and the second sensing line are respectively embedded in the keel spiral to form a line shape;

[0041] The water leakage sensing line 4 is made of two conductive polymers. Under normal circumstances, the two conductive polymers are insulated. When there is water between the two conductive polymers, the two conductive polymers are connected due to the conductive property of the water, causing the change of the resistance value of the entire sensing line loop. The change of the resistance value causes the current in the water leakage sensing line 4 to change. After the water leakage sensing line 4 is connected to the detection mechanism, a conductive path is formed. By observing the current value displayed on the ammeter, it is determined whether there is water accumulation in the optical cable box 1;

[0042] In this embodiment, the detection mechanism is an external mechanism, so there is no need to provide a power supply for the water leakage sensing line 4 in the optical cable box 1 , and it is mainly used to determine whether there is water accumulation in the optical cable box 1 .

[0043] In this embodiment, the optical cable box 1 includes a box body 11 and a box cover 12 , the box body 11 and the box cover 12 are connected by a hinge, the connecting plate 2 is arranged in the box body 11 , and the wire connector 6 is installed on the box cover 12 .

[0044] In this embodiment, a detection box 5 is further included, the detection box 5 is fixed on the box cover 12, and the wire connector 6 is located in the detection box 5;

[0045] When the detection box 5 is opened, the detection mechanism can be directly connected to the wire connector 6 to facilitate detection of whether there is water accumulation in the optical cable box 1.

[0046] The second embodiment of the utility model:

[0047] Preferably, the detection mechanism includes a water leakage controller, an alarm and a power supply, the water leakage controller wire interface is connected to the wire connector 6, the water leakage controller, the alarm and the water leakage sensing line 4 are all electrically connected to the power supply, and the detection mechanism is arranged in the detection box 5;

[0048] In this embodiment, the detection mechanism is fixedly installed and fixed in the detection box 5. When water accumulates in the optical cable box 1, the two conductive polymers of the water leakage sensing line 4 are connected due to the conductivity of the water, causing the resistance value of the entire sensing line loop to change. The change in resistance value causes the current in the water leakage sensing line 4 to change. After the water leakage controller receives the current change, it warns through the alarm, thereby realizing the role of real-time monitoring.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
