[0023] In the prior art, due to the certainty of the external environment of the pipeline, there is groundwater, surface seepage water and other wet conditions outside the pipeline after installation. The traditional water leakage alarm uses the change of the resistance of the seepage water loop to check, but the uncertain external environment may cause the water leakage alarm to be falsely triggered, resulting in poor accuracy of pipeline water leakage alarm detection. Therefore, the inventor provides a pipeline leakage detection alarm device after research to solve the above defects.

[0024] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please refer to Figures 1 to 4 The utility model provides a pipeline leakage detection alarm device, comprising a pipeline body 1 and detection tubes 4 equidistantly installed on the pipeline body 1, a power supply frame 3 fixed to the outer wall of the pipeline body 1 is arranged between the two detection tubes 4, and telescopic blocks 11 are elastically inserted in the two detection tubes 4, wherein the inner wall of the detection tube 4 is equidistantly embedded with electrode rings 12, and the telescopic blocks 11 are sleeved with electrode rings 12 electrically connected to the electrode rings 12, and indicator lights 18 are equidistantly installed at both ends of the power supply frame 3, and a counting controller 15 (preferably a METONE type counting controller 15) is embedded and fixed at the top of the power supply frame 3, wherein an alarm 17 electrically connected to the counting controller 15 is embedded and fixed on the side wall of the power supply frame 3, when leakage occurs in the pipeline body 1, the pressure in the pipeline body 1 decreases, the elastic force of the spring 14 pushes the telescopic block 11 to slide on the power supply frame 3, and separates the electrode tube 10 from part of the electrode rings 12 during the sliding process, thereby turning off part of the indicator lights 18, and the technical controller starts the alarm 17 to alarm after detecting a change in the number of indicator lights 18.

[0026] Mounting rings 2 are fixedly sleeved on both sides of the outer wall of the pipeline body 1, and screw holes 8 are opened on the outer walls of the two mounting rings 2. A threaded portion 5 is fixed to the bottom end of the detection tube 4, and the threaded portion 5 is threadedly inserted in the screw hole 8. Connecting wires 6 fixed to the mounting ring 2 are installed at both ends of the power supply frame 3, and the connecting wires 6 are electrically connected to the electrode tube 10 and multiple electrode rings 12 respectively. A spring 14 is embedded in the detection tube 4, and an adjustment plate 7 is threadedly inserted on the side wall of the detection tube 4. The threaded portion 5 is threadedly inserted in the screw hole 8 on the outer wall of the mounting ring 2. The detection tube 4 is installed and removed by rotating the threaded portion 5. At the same time, an adjusting plate 7 is threadedly inserted on the side wall of the detection tube 4, and the adjusting plate 7 is driven to rotate through the groove 13, and the elastic force of the spring 14 is adjusted during the rotation. It is suitable for leakage detection of pipeline bodies 1 with different pressures.

[0027] The two ends of the spring 14 are respectively in contact with the adjustment plate 7 and the telescopic block 11, and the side wall of the adjustment plate 7 is symmetrically provided with grooves 13. The detection tube 4 is connected to the pipeline body 1, and the inner wall of the detection tube 4 is fixed with an anti-detachment part 9, and the telescopic block 11 is engaged with the anti-detachment part 9. The anti-detachment part 9 prevents the telescopic block 11 from being squeezed and falling off by the spring 14. A battery is embedded in the power supply frame 3, and multiple indicator lights 18 are electrically connected to the battery. The alarm 17 is inserted into the power supply frame 3, and the side wall of the alarm 17 is fixed with a power supply terminal connected to the battery. The bottom end of the power supply frame 3 is fixed with a mounting seat 16, and the mounting seat 16 is fixedly connected to the outer wall of the pipeline body 1. The pressure in the pipeline body 1 squeezes the telescopic block 11 and the spring 14, so that the telescopic block 11 is in a relatively stable state. At the same time, the electrode tube 10 on the telescopic block 11 contacts the electrode ring 12 on the detection tube 4, so that the indicator light 18 on the power supply frame 3 lights up, and multiple motor rings correspond to multiple indicator lights 18 respectively. When a leak occurs in the pipeline body 1, the pressure in the pipeline body 1 decreases, and the elastic force of the spring 14 pushes the telescopic block 11 to slide on the power supply frame 3, and during the sliding process, the electrode tube 10 is separated from part of the electrode ring 12, thereby turning off part of the indicator lights 18. After the technical controller detects a change in the number of indicator lights 18, it activates the alarm 17 to sound an alarm.

[0028] In summary, the pressure in the pipeline body 1 squeezes the telescopic block 11 and the spring 14, so that the telescopic block 11 is in a relatively stable state. At the same time, the electrode tube 10 on the telescopic block 11 contacts the electrode ring 12 on the detection tube 4, so that the indicator light 18 on the power supply frame 3 is on, and multiple motor rings correspond to multiple indicator lights 18. When the pipeline body 1 leaks, the pressure in the pipeline body 1 decreases, and the elastic force of the spring 14 pushes the telescopic block 11 to slide on the power supply frame 3, and in the process of sliding, the electrode tube 10 is separated from part of the electrode ring 12, so that part of the indicator lights 18 are extinguished. After the technical controller detects the change in the number of indicator lights 18, it activates the alarm 17 to alarm. The above is only a preferred embodiment of the utility model, and is not used to limit the utility model. For technicians in this field, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
