[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings.

[0033] Centrifugal rods 15 are arranged around the top of the main rotating shaft 8 at equal intervals. Each centrifugal rod 15 is rotatably connected to the top of the main rotating shaft 8.

The top of each centrifugal rod 15 is rotatably connected to the polyhedral cylindrical loading block 13 through a pin and a hinge seat 14.

The number of side planes of the pad 17 is equal to the number of side planes of the polyhedral cylindrical loading block 13, and the side planes of the pad 17 are all provided with arc-shaped grooves.

[0039] The left side of each electronic component assembly box 18 is fixedly connected to the left side of the inner wall of the monitoring chamber 4 by screws, and the right front end of each electronic component assembly box 18 is fixedly installed with a limiting guide tube 19 by screws. The inner front end of each limiting guide tube 19 is fixedly installed with a lightweight spring 20, and the rear end of each lightweight spring 20 is fixedly connected to the front end of the telescopic rod 21.

[0040] When the lightweight spring 20 is in the normal reset state, the iron sheet 22 contacts the inner wall of the sensing chamber 3. The side wall cross-section of the sensing chamber 3 is a quarter-circular arc and its center is located on the circular path surrounded by the pin shaft in the hinge seat 14. The distance between each magnet 16 and the inner wall of the sensing chamber 3 is less than the maximum magnetic force action distance between the two.

[0041] A retaining ring 25 is fixed on the front end of the middle part of the telescopic rod 21, and a strip-shaped block 26 is fixed on the top and bottom of the front end of the right side of the electronic component assembly box 18 and aligned with the retaining ring 25.

[0042] A small rack 23 is fixedly provided on the middle part of the left side of the telescopic rod 21. The potentiometer gear switch 24 consists of a gear and a potentiometer.

[0043] Working principle: The equipment is connected to the building water supply pipe through the mounting flange 2. When the water flows through, the turbine 9 is driven to rotate. The main rotating shaft 8 of the turbine 9 is linked to the transmission rotating shaft 11 through the first bevel gear 10 and the second bevel gear 12. After the transmission rotating shaft 11 starts to rotate, it generates centrifugal force on the centrifugal rod 15 and the magnet 16 carried thereon, so that the two are gradually rotated and lifted. The lifting height changes with the flow rate of the water flow. In the process of rotation and lifting, it will continuously approach or move away from each iron sheet 22. The magnetic force causes the iron sheet 22 and the telescopic rod 21 to be pulled out from the limiting conduit 19, and the block 26 and the retaining ring 25 limit its maximum withdrawal length to prevent the iron sheet 22 from contacting the magnet 16 and causing interference. The lightweight spring 20 will reset the iron sheet 22 and the telescopic rod 21 after the magnet 16 is away from the current iron sheet 22.

[0044] During this process, the telescopic rod 21 that is attracted and pulled out or reset after being released from attraction will drive the potentiometer gear switch 24 to rotate through the small rack 23. When pulled out, the corresponding water flow rate display light 27 will gradually brighten. When reset, the water flow rate display light 27 will gradually dim until it goes out. The higher the position of the lit water flow rate display light 27, the faster the water flow rate.

[0045] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
