DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] like Figure 1 As shown, the electronic water meter auxiliary detection device comprises a positioning cover 1. The shape of the positioning cover is consistent with the shape of the meter cover 11 on the top of the water meter.

[0026] The four edges of the positioning cover are provided with downwardly extending retaining edges 1-1, and when the positioning cover is installed on the water meter, the retaining edges surround the side of the meter cover to prevent the positioning cover from shaking. A notch 1-8 is provided on the retaining edge to avoid the battery compartment on the side of the water meter.

[0027] The positioning cover is provided with a detection platform 1-2, which protrudes upward from the top surface of the positioning cover. The detection platform is a shell structure, and the top surface of the detection platform is provided with a top cover 1-3. A main board 2 is fixed inside the detection platform, and an infrared sensor 3 and a light sensor 4 are fixed on the bottom surface of the main board.

[0028] The positioning cover is provided with observation windows 1-4, cover holes 1-5, and openings 1-6. The cover holes are arranged on the side of the detection platform, corresponding to the position of the cover mounting seat of the water meter, and are used to avoid the cover mounting seat. The observation window corresponds to the position of the display screen of the water meter to avoid blocking the display screen. The observation window runs through the detection platform and the positioning cover, and the observation window is respectively connected to the top surface of the detection platform and the bottom surface of the positioning cover, and the observation window is separated from the inner cavity of the detection platform by a baffle 1-7. The opening corresponds to the position of the signal window of the water meter, and the opening is connected to the inner cavity of the detection platform, and the infrared sensor and the optical sensor extend into the opening.

[0029] A switch 5 is also provided on the top cover of the detection platform, and the switch is electrically connected to the main board. The main board is electrically connected to the external calibration platform through a wire (omitted in the figure).

[0030] like Figure 7 As shown, a display screen 12, a signal window 13 (with a built-in signal light and an infrared sensor), and a meter cover mounting seat 14 (for mounting the meter cover) are provided on the meter cover 11 of the water meter, and a battery compartment 15 is also provided on the side of the meter cover of the water meter.

[0031] The working principle of the utility model is:

[0032] 1. Remove the water meter cover, such as Figure 8 As shown in the figure, put the positioning cover downwards onto the meter cover of the water meter;

[0033] 2. Press down the positioning cover, make the retaining edge of the positioning cover close to the side of the meter cover, and make the bottom surface of the positioning cover close to the top surface of the meter cover to avoid the positioning cover from shaking and ensure the stable transmission of the signal during detection; at this time, the water meter display screen is located in the observation window, and the infrared sensor and the light sensor are aligned with the signal window of the water meter;

[0034] 3. Press the switch to start the test;

[0035] 4. The infrared sensor of the positioning cover sends a detection command. After the infrared sensor of the water meter receives the command, the water meter enters the identification mode;

[0036] 5. When the flow starts, water flows continuously through the water meter, driving the internal components of the water meter to operate, and the water meter measures the water flow;

[0037] 6. The signal light of the water meter keeps flashing, converting the metering data of the water meter into light pulse signals in real time. At the same time, the metering data is displayed on the display screen of the water meter, and the staff can view it through the observation window;

[0038] 7. The main board of the positioning cover receives the optical pulse signal through the optical sensor, converts the optical pulse signal into an electrical signal, and sends it to the calibration station through a wire;

[0039] 8. The calibration station checks the actual flow data with the water meter data collected by the positioning cover to detect whether the water meter performance meets the factory requirements.

[0040] All components of the utility model are prior art and can be purchased from outside.

[0041] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
