Detailed Description

For making the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following drawings in the embodiments of the present invention will be combined, and the technical solution in the embodiments of the present invention is clearly and completely described, based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work are included in the protection scope of the present invention.

Referring to fig. 1 to 4, a multi-probe leakage detection device box according to an embodiment of the present invention includes a box body 1 having a cavity therein, a pressure transmitter connected to one side of the box body 1 for detecting pressure in a pipeline, a water-sound sensor connected to one side of the box body 1 for detecting water-sound frequency in the pipeline, and a wireless transmission module connected to the other side of the box body 1 for transmitting signals to a signal processing terminal; the cavity of the box body 1 is provided with a signal processing module used for respectively amplifying signals detected by the pressure transmitter and the water sound sensor, and the wireless transmission module transmits the signals amplified by the signal processing module to the signal processing terminal.

In this application, one side end of box body 1 is connected with pressure transmitter and water sound sensor respectively, and another side is connected with wireless transmission module, when carrying out the seepage detection of pipeline, installs pressure transmitter and water sound sensor respectively on the check point of pipeline, and pressure transmitter is used for measuring the water pressure in the pipeline, and water sound sensor is used for measuring the frequency of underwater sound in the pipeline. In the present application, the pressure transmitter may be a PT124B-218 series pressure transmitter from Shanghai Korea pressure instruments, inc., the water sound sensor may be a DPTZ-2KA type sound sensor from Beijing Asia Aldrich technologies, inc.,

in the actual measurement process, the water pressure change and the sound frequency change at the leakage point of the pipeline are possibly small, so that electric signals transmitted by the pressure transmitter and the water sound sensor are weak, and therefore, the signal processing module is arranged in the cavity of the box body 1 and used for amplifying the electric signals transmitted by the pressure transmitter and the water sound sensor, the detection result is more obvious and visual, and the judgment of the leakage point of the pipeline is more accurate. The wireless transmission module at the other side end of the box body 1 transmits the electric signals transmitted by the signal processing module to the signal processing terminal, and the signal processing terminal analyzes and processes the received electric signals so as to judge the position of a leakage point of the pipeline.

The existing pipeline leakage detection equipment usually only adopts a water sound sensor to detect a pipeline leakage point, the detection distance of the pipeline leakage point is limited because the sound frequency which can be detected by the water sound sensor is limited, in actual use, for the detection of a longer pipeline leakage point, the detection point of one water sound sensor is usually set at intervals, and the signal processing terminal analyzes electric signals transmitted by a plurality of water sound sensors, so that the position of the pipeline leakage point is judged. However, when detecting underwater sound, the underwater sound sensors are easily affected by external factors, so that in actual detection, a plurality of underwater sound sensors may detect abnormal underwater sound frequency simultaneously, which causes inaccurate leakage detection of the pipeline and requires one-to-one inspection by detectors, which brings great difficulty to leakage detection of the pipeline and increases labor intensity and detection time of the detectors.

In this application, when the leak source to longer pipeline detects, set up a check point every a section distance, the equipment box of this application is all placed to every check point, and pressure transmitter measures pipeline water pressure on each check point, and water sound sensor detects this one section underwater sound frequency simultaneously.

However, in the foregoing, when detecting a leak in a pipe, the sound in the pipe is easily affected by the external environment, so that there is a possibility that the sound frequency changes in many places, and in this case, it is difficult to determine the location of the leak in the pipe only by analyzing the sound frequency waveforms transmitted by the plurality of water sound sensors.

In the application, each detection point is provided with one pressure transmitter to measure the water pressure of the pipeline, the water pressure detected by two adjacent pressure transmitters is compared to determine which section of the pipeline the leakage point is positioned in, and then the sound sensor which is superposed with the section detects the change of sound frequency, so that the sound frequency detected by the water sound sensor of the section can be determined to be the change of sound at the leakage point, and the signal processing terminal analyzes the sound frequency waveform transmitted by the water sound sensor, thereby determining the specific position of the leakage point.

The electric signals detected by the pressure transmitter and the water sound sensor are amplified through the amplifying integrated circuit on the PCB circuit board 2, so that the detection of the equipment box to the pipeline leakage point is more accurate and visual, the detection range of the equipment box is enlarged, and the practicability of the equipment box is stronger.

The cavity of the box body 1 is provided with a battery pack 3 which is used for supplying power to the integrated circuit on the PCB circuit board 2. Therefore, the battery pack 3 for supplying power to the PCB 2 is separately provided in the case 1, instead of supplying power to the PCB 2 by using an external power source, so as to make the use of the apparatus case more convenient. In the foregoing, when a leak of a long pipeline is detected, one detection point is set at intervals, and each detection point is provided with one device box of the present application, so that in actual use, a plurality of device boxes are used together, and each detection point is provided with an external power supply to supply power to the PCB 2 in the device box, which not only requires higher space for the detection point, but also increases the cost for detecting the leak of the pipeline; if the same external power supply is used for supplying power to the PCB circuit board 2 in the equipment box, the power connection of a plurality of equipment boxes and the external power supply is complex, and the equipment boxes are inconvenient to use.
