[0051] See also Figure 1 、 Figure 4 A water flow indicator assembly provided in an embodiment of the present application includes a water flow indicator 100, wherein the water flow indicator 100 has an internally threaded water inlet 105 and an internally threaded water outlet 106 on opposite sides thereof; further comprising a first pipe joint 200 and a first ear plate 300, wherein the outside of the first pipe joint 200 is connected to a first limit block 400, and a first through hole 301 is provided on the first ear plate 300, and one end of the first pipe joint 200 passes through the first through hole 301 and is threadedly and sealedly connected to the internally threaded water inlet 105, and the first ear plate 300 is pressed tightly by the first limit block 400.

[0052] See also Figure 1The water flow indicator 100 is a device that determines the flow state of liquid in a pipe by observing whether the impeller inside it is rotating. For example, the left side of the water flow indicator 100 has an internally threaded water inlet 105, and the right side of the water flow indicator 100 has an internally threaded water outlet 106, thereby allowing the water flow indicator 100 to be connected to the pipe using a threaded connection.

[0053] See also Figure 1 The first pipe joint 200 is a component for connecting pipes.

The operating status of the water pump can then be determined by observing whether the impeller in the water flow indicator 100 is rotating. Specifically: 1) When the water pump is stopped, the impeller is observed to be stationary, indicating that the pump is stopped and leak-free. 2) When the water pump is started, the impeller is observed to be rotating, indicating that the pump is started. If the impeller speed is significantly lower than normal, it can be determined that the pump is partially blocked and requires repair.

[0056] The water flow indicator assembly provided in an embodiment of the present application is threadedly and sealedly connected to the internally threaded water inlet 105 of the water flow indicator 100 by passing the first pipe joint 200 through the first through hole 301 on the first ear plate 300, and the first limit block 400 on the first pipe joint 200 is used to press the first ear plate 300, thereby connecting the water flow indicator 100 and the first ear plate 300 together.

[0064] See also Figure 5 The second limiting block 700 is connected to the outer surface of the second pipe joint 500, see Figure 8 The second lug plate 600 is provided with a second through hole 601 for the left end of the second pipe joint 500 to pass through. After the left end of the second pipe joint 500 passes through the second through hole 601 and is threadedly and sealedly connected to the internally threaded water outlet 106, the second lug plate 600 can be pressed against the water flow indicator 100 by the second stopper 700, thereby firmly connecting the second lug plate 600 and the water flow indicator 100.

[0065] The water flow indicator assembly provided in the present embodiment, by providing a first lug 300 and a second lug 600, allows the water flow indicator 100 to be simultaneously secured to the structural member via the first lug 300 and the second lug 600. This further enhances the secure fixation of the water flow indicator 100, prevents the water flow indicator 100 from shaking due to pipeline vibration or fluid flow, and ensures accurate observation and device stability. The detachable connection between the second pipe joint 500, the second lug 600, and the water flow indicator 100 allows for quick removal of the water flow indicator 100 when needed, facilitating maintenance and inspection, and reducing maintenance time and costs.

[0066] The second limiting block 700 may be an annular structure, which is sleeved on the second pipe joint 500 and welded or integrally formed with the second pipe joint 500 .

[0067] In some embodiments, see Figure 6 The second stopper 700 includes a second nut threadedly connected to the second pipe connector 500. This threaded connection allows the operator to rotate the second nut to adjust its pressure on the second lug 600, ensuring a secure connection.

[0069] The second ear plate 600 can be fixedly connected to the structural member by welding, bolt connection, etc. When the structural member is a steel pipe, in order to increase the contact area between the second ear plate 600 and the steel pipe, see Figure 8 One end of the second ear plate 600 is provided with a second arc-shaped positioning groove 602. The shape and size of the second arc-shaped positioning groove 602 are adapted to the size and shape of the outer surface of the steel pipe.

The impeller 102 is rotatably installed in the impeller cavity 103. An observation window 104 for observing the impeller 102 is provided on the indicator seat 101. An internal threaded water inlet 105 and an internal threaded water outlet 106 connected to the impeller cavity 103 are respectively provided on opposite sides of the indicator seat 101.

[0071] During use, when water flows into the impeller chamber 103 through the internal threaded water inlet 105 and is discharged through the internal threaded water outlet 106, the water flow drives the impeller 102 to rotate in the impeller chamber 103; the worker can observe whether the impeller 102 is rotating through the observation window 104, and then judge the flow state of the liquid in the pipeline.

[0072] The indicator base 101 can be made of a metal material, such as stainless steel. In some embodiments, the indicator base 101 is made of transparent acrylic glass, so that the indicator base 101 can form the observation window 104 as a whole, without the need to provide a separate observation window 104, thereby reducing manufacturing difficulty and manufacturing cost.
