The utility model can conveniently and intuitively observe the liquid flow and has a certain digital representation meaning, reduces the influence of low liquid transparency on observation, and has a low cost. However, this liquid flow indicator still has deficiencies. When the liquid level height in the pipeline changes, the height change of the liquid level may cause the indicator to be completely immersed in the liquid or exposed above the liquid level, affecting its normal operation. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a liquid flow indicator, which solves the problem that when the liquid level height in the pipeline changes, the height change of the liquid level may cause the indicator to be completely immersed in the liquid or exposed above the liquid level, affecting its normal operation.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A liquid flow indicator includes a flow indicator body, and an air floating assembly is arranged below the flow indicator body.

[0013] Beneficial effects

[0014] The utility model provides a liquid flow indicator. Compared with the prior art, the following beneficial effects are achieved:

[0015] 1. In the utility model, through the arranged air flotation component, during the use of the liquid flow indicator, if there is a situation where the liquid level in the pipeline where the liquid flow indicator is installed changes, under the buoyancy of the liquid in the pipeline on the outer sides of the plurality of air bags of the air charging pipe, when the liquid level in the pipeline rises, the plurality of air bags together with the lifting ring move upward. At this time, the flow indication component also moves upward. When the liquid level in the pipeline drops, the flow indication moves downward. Through the air flotation mechanism, the indicator can automatically adjust its position to adapt to the fluctuations and changes of the liquid level, ensuring continuous and accurate flow detection, and there is no need to manually adjust the position of the indicator frequently, saving human resources and reducing the operation difficulty;

[0016] 2. In the present utility model, through the provided flow indication assembly, after installing the liquid flow indicator at the pipeline flow monitoring position, as the liquid in the pipeline flows, the water flow thrust generated during the liquid flow triggers the rotation of the guide vane. As the guide vane rotates, the rotating shaft connected to it rotates accordingly.

[0025] Embodiment 1:

[0026] A liquid flow indicator, comprising a flow indicator body 1, a pneumatic floating assembly is arranged below the flow indicator body 1. The pneumatic floating assembly includes an air pump 401, an air guide pipe 402, an air filling pipe 403 and an air bag 404. A plurality of air bags 404 are arranged outside the air filling pipe 403. The plurality of air bags 404 are distributed in an annular array outside the air filling pipe 403, and the plurality of air bags 404 communicate with the air filling pipe 403. An air guide pipe 402 is arranged on one side of the upper surface of the air filling pipe 403. One end of the air guide pipe 402 away from the air filling pipe 403 is provided with an air pump 401. The air pump 401 is fixedly connected to the rear side of the flow indicator body 1, and the air outlet end of the air pump 401 is connected to the air guide pipe 402. When the air volume in the air bag 404 is insufficient, the air pump 401 is used to fill the air guide pipe 402 with air. The inflowing air flows through the air guide pipe 402 and the air filling pipe 403 to the positions of the plurality of air bags 404, so that the volume of the air bag 404 increases.

[0027] During operation, when the liquid level in the pipeline where the liquid flow indicator is installed changes during the use of the liquid flow indicator, under the buoyancy of the liquid in the pipeline and the plurality of air bags 404 outside the air filling pipe 403, when the pipeline liquid level rises, the plurality of air bags 404 and the lifting ring 405 move upward together. At this time, the flow indicating assembly also moves upward. When the pipeline liquid level drops, the flow indication moves downward. Through the pneumatic floating mechanism 4, the indicator can automatically adjust its position to adapt to the fluctuations and changes of the liquid level, ensuring continuous and accurate flow detection, and there is no need to manually adjust the position of the indicator frequently, saving human resources and reducing the operation difficulty.
