[0017] A method for using a portable water meter testing device: The aforementioned portable water meter testing device based on AI visual recognition can perform airtightness testing and metering testing on ultrasonic water meters, and can also perform descaling and cleaning.
[0018] When performing airtightness fault testing:
[0019] S10: Install the sealing end cap on the meter tube interface of the detection body, and connect the air tube interface of the detection body to the air pump; turn on the air pump, apply air pressure to the sealing tube, and use the air pressure monitoring head to detect the air tightness of the sealing tube.
[0020] S20: If the airtightness of the sealing tube is qualified, remove the sealing end cap and install it on the pipe section port on the water outlet side of the ultrasonic water meter. Connect the meter pipe interface of the testing body to the pipe section port on the water inlet side of the ultrasonic water meter. Turn on the air pump to apply air pressure and use the air pressure monitoring head to test the airtightness of the ultrasonic water meter pipe section. If the airtightness of the sealing tube is unqualified, check the airtightness of the testing body.
[0021] When performing metering fault detection:
[0022] S30: Connect the air pipe interface of the detection body to the air pump, and connect the meter pipe interface of the detection body to the pipe section port on the water inlet side of the ultrasonic water meter.

[0023] S40: The control box converts the detection results of the ultrasonic water meter and compares the converted data with the detection data of the flow monitoring head. If the difference between the two is within the error range, it indicates that the ultrasonic metering function is normal; if the difference is outside the error range, it indicates that the metering function is abnormal and simultaneously displays the detection results of the flow guide.

[0048] Reference Figures 1 to 7A portable water meter testing device based on AI visual recognition includes a testing body and a sealing end cap 2. The testing body includes a base 1, with support legs 11 at the bottom and soft pads at the bottom of the support legs 11. A sealing tube 4 and a control box 5 are mounted on the base 1. An air pipe interface 41 is provided on one side of the sealing tube 4, which is connected to an external air pump. A meter pipe interface 42 is provided on the other side of the sealing tube 4, which is used to connect to the pipe section port on the water inlet side of the ultrasonic water meter 3. A gas detection module 6 is provided on the sealing tube 4, which has a flow monitoring head 61 and a pressure monitoring head 62, which extend into the sealing tube 4. A display control panel 51 is provided on the control box 5, and a wireless connection module is provided inside the control box 5 for wireless connection with the ultrasonic water meter 3.
[0049] This embodiment can perform airtightness testing and metering testing on the ultrasonic water meter 3. The method of use is as follows:
[0050] When performing airtightness fault testing, first test the airtightness of the testing equipment. Install the sealing end cap 2 on the meter pipe interface 42 of the testing body, and connect the air pipe interface 41 of the testing body to the air pump. Turn on the air pump and apply air pressure to the sealing pipe 4, using the air pressure monitoring head 62 to test the airtightness of the sealing pipe 4. If the airtightness of the sealing pipe 4 is qualified, remove the sealing end cap 2 and install it on the pipe section port on the water outlet side of the ultrasonic water meter 3. Connect the meter pipe interface 42 of the testing body to the pipe section port on the water inlet side of the ultrasonic water meter 3. Turn on the air pump and apply air pressure, using the air pressure monitoring head 62 to test the airtightness of the ultrasonic water meter 3 pipe section. If the airtightness of the sealing pipe 4 is unqualified, check the airtightness of the testing body.
[0051] When performing metering fault detection, firstly, connect the air pipe interface 41 of the detection unit to the air pump, and connect the meter pipe interface 42 of the detection unit to the pipe port on the water inlet side of the ultrasonic water meter 3. Turn on the air pump, and the ultrasonic water meter 3 detects the airflow, while the flow monitoring head 61 also detects the airflow. The control box 5 converts the detection results of the ultrasonic water meter 3 and compares the converted data with the detection data of the flow monitoring head 61. If the difference between the two is within the error range, it indicates that the ultrasonic metering function is normal; if the difference is outside the error range, it indicates that the metering function is abnormal.
[0052] As a specific embodiment, the sealing tube 4 is also equipped with an AI visual recognition module 7. The AI visual recognition module 7 includes a module body that extends into the sealing tube 4 and has a visual detection head 71 at its end. The visual detection head 71 has a camera 72 on the side facing the air pipe interface 42, and an illumination element 73 is arranged around the camera 72. The detection head is conical on the side facing the air pipe interface 41 to guide the airflow and reduce the frontal resistance of the visual detection head 71.
[0053] The difference between this embodiment and the previous embodiment is that: the sealing pipe 4 is equipped with an AI visual recognition module 7, and the visual detection head 71 detects the flow guide located in the ultrasonic water meter 3 pipe section. Loose flow guides can cause metering failures, and the visual detection head 71 is used to detect whether the flow guide is loose. When detecting metering failures in the ultrasonic water meter 3, the control box 5 displays the detection results of the AI visual recognition module 7 simultaneously with the detection results, to help the testing personnel eliminate the influencing factors of the flow guide when detecting metering failures.
[0054] In one specific embodiment, the meter pipe interface 42 is provided with a first flange 43, the outer side of the first flange 43 mates with the inner side of the pipe section of the ultrasonic water meter 3. The sealing end cap 2 is provided with a second flange 21 in the middle, the outer side of the second flange 21 mates with the inner side of the first flange 43. Preferably, the first flange 43 and the pipe section of the ultrasonic water meter 3, and the second flange 21 and the first flange 43, can be sealed by threaded connection.
[0055] The difference between this embodiment and the above embodiment is that the detection body can be assembled and connected with the sealing end cap 2, which is conducive to the storage of the equipment and convenient for the testing personnel to carry.
[0056] In one specific embodiment, the sealing end cap 2 is provided with a pressurizing chamber, in which a pressurizing cleaning component 22 is assembled. The pressurizing cleaning component 22 includes an impeller end and a spray end; the spray end is provided with a through spray hole 23. The impeller end includes a connecting shaft 24, and drive blades 25 are circumferentially arranged on the side of the connecting shaft 24. A slope 26 is provided between the drive blades 25, and the spray hole 23 communicates with the slope 26. The spray hole 23 is inclined outward, and the inner side of the second flange 21 is inclined outward. One end of the sealing end cap 2 is provided with a water pipe interface 27, which is eccentrically arranged. A sealing cap 28 is assembled on the water pipe interface 27, and the sealing cap 28 is provided with friction texture.
[0057] The difference between this embodiment and the above embodiment is that the sealing end cap 2 is connected to the water pipe and can be used for descaling and cleaning the ultrasonic water meter pipe section without disassembling the ultrasonic water meter 3, making descaling simple. During descaling and cleaning, the sealing cap 28 is removed and the water pipe interface 27 is connected to the water pipe. The sealing end cap 2 is then installed on the pipe section port on the water outlet side of the ultrasonic water meter 3. Water is supplied to the pipe, and the water flow drives the pressure cleaning component 22 to rotate. Simultaneously, water is sprayed from the spray hole 23, pressurizing and flushing the scale located on the inner wall of the ultrasonic water meter 3 pipe section.
[0058] The scope of protection of this invention includes, but is not limited to, the above embodiments. The scope of protection of this invention is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art fall within the scope of protection of this invention.
