[0023] like Figures 1 to 3As shown, a flow liquid metering and detection device comprises a liquid flow meter 1 and a measuring conduit 2, a filter screen 3 for preventing the measuring conduit 2 from being blocked is fixedly provided on the surface of the measuring conduit 2, an anti-blocking component 4 for cleaning the filter screen 3 is provided on the inner wall of the measuring conduit 2 and the surface of the filter screen 3, a fixing plate 5 is fixedly provided on the surface of the liquid flow meter 1, and cavities are opened on both side surfaces of the fixing plate 5, a floating plate 6 for floating the entire device on the liquid surface is slidably provided on the inner wall of the cavity, a contraction driving mechanism 7 for driving the floating plate 6 to contract inside the cavity is provided on the top of the fixing plate 5 and one side wall of the floating plate 6; specifically, the floating plate 6 can slide on the inner wall of the cavity through the contraction driving mechanism 7, This causes the float plate 6 to shrink. When the float plate 6 slides to the inside of the cavity, the volume of the device is reduced, thereby achieving the effect of being easy to carry. When part of the float plate 6 slides to the outside of the cavity, the device can float on the surface of the liquid, and the measuring tube 2 and the filter screen 3 are immersed in the liquid. The liquid flows into the inside of the measuring tube 2, and the flow rate of the flowing liquid is detected through the liquid flow meter 1. Large particles of impurities in the flowing liquid can be filtered through the filter screen 3, thereby preventing the measuring tube 2 from being blocked. The anti-blocking component 4 can be driven during the liquid flow process, and the surface of the filter screen 3 can be cleaned by the anti-blocking component 4, thereby preventing the filter screen 3 from being blocked, thereby ensuring the normal detection effect of the liquid flow meter 1.

[0029] In summary: the contraction drive mechanism 7 can make the float plate 6 slide on the inner wall of the cavity, thereby causing the float plate 6 to contract. When the float plate 6 slides to the inside of the cavity, the volume of the device is reduced, thereby achieving the effect of being easy to carry. When part of the float plate 6 slides to the outside of the cavity, the device can float on the surface of the liquid, and the measuring tube 2 and the filter screen 3 are immersed in the liquid. The liquid flows into the inside of the measuring tube 2, and the flow rate of the flowing liquid is detected through the liquid flow meter 1. The large particles of impurities in the flowing liquid can be filtered through the filter screen 3, thereby preventing the measuring tube 2 from being blocked. The anti-blocking component 4 can be driven during the liquid flow process, and the surface of the filter screen 3 can be cleaned by the anti-blocking component 4, thereby preventing the filter screen 3 from being blocked, thereby ensuring the normal detection effect of the liquid flow meter 1.
