However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.
[0029] Example 1, as shown in the attached document Figure 2 , Figure 4 and Figure 5 As shown, it includes a dial 8, a limiting mechanism 21 and a friction mechanism 2. The limiting mechanism 21 includes a limiting ring 214 and a first ball 213. The side surface of the limiting ring 214 is movably connected to the first ball 213. The limiting ring 214 and the first ball 213 can limit the rotation and prevent it from shifting.
[0030] The friction mechanism 2 includes a blade 204 and a friction seat 205. The friction seat 205 is made of rubber. The blade 204 and the friction seat 205 are used to squeeze and discharge impurities, making it convenient to clean the impurities.
[0031] The overall effect of Embodiment 1 is as follows: the limiting ring can limit the rotation shaft 10, the first ball 213 can fit with the surface of the rotation shaft 10 to prevent the impeller 4 from rotating off-center. At the same time, the blade 204 can drive the friction seat 205 to rotate and rub inside the filter box 1 to clean impurities.
[0032] Example 2, as Figure 2 and Figure 5 As shown, the limiting mechanism 21 also includes a hollow plate 211, an adjusting plate 212 is slidably connected inside the hollow plate 211, and the side surface of the adjusting plate 212 is fixedly connected to the side surface of the limiting ring 214. A fixing rod 217 passes through the upper surface of the hollow plate 211, and the bottom end of the fixing rod 217 is fitted into the interior of the adjusting plate 212. A curved tube 216 is fixedly connected to the upper surface of the limiting ring 214, and a second ball bearing 215 is movably connected to the top end of the curved tube 216.
[0033] The effect achieved by the entire embodiment 2 is as follows: when the top end of the rotating shaft 10 penetrates the interior of the fitting tube 6, the adjusting plate 212 can be pulled to one side by sliding the adjusting plate 212 and the hollow plate 211, so that the limiting seat can limit the rotating shaft 10, and the curved tube 216 can move together with the limiting seat. By using the contact between the first ball 213 and the second ball 215 and the rotating shaft 10, the first ball 213 can roll inside the limiting seat when the rotating shaft 10 rotates, and the second ball 215 can roll in the curved tube 216, thereby improving the stability of the impeller 4 when rotating.

[0035] The effect achieved by the entire embodiment 3 is as follows: the movable ring 201 is fitted into the interior of the filter box 1. By utilizing the lateral arrangement of the blades 204, when water enters the interior of the filter box 1, the blades 204 are affected by the water impact and can drive the movable ring 201 to rotate inside the filter box 1. By utilizing the contact between the friction seat 205 and the inner wall of the filter box 1, it can squeeze and rub the impurities stuck in the mesh of the filter box 1 and make them fall off the mesh of the filter box 1, thereby improving the measurement accuracy of the device. Since the diameter and width of the movable ring 201 and the blades 204 are larger than those of the impeller box 3, they will not affect the rotation of the movable ring 201.

The upper surface of the second gear 19 is fixedly connected to the third drive wheel 16. The upper surface of the gear plate 7 is movably connected to the third gear 20 through a bearing, and the third gear 20 is meshed with the third drive wheel 16. The upper surface of the third gear 20 is fixedly connected to the fourth drive wheel 15. The upper surface of the gear plate 7 is movably connected to the fourth gear 11 through a bearing, and the fourth gear 11 is meshed with the fourth drive wheel 15. The upper surface of the fourth gear 11 is fixedly connected to the worm gear 12. The upper surface of the gear plate 7 is fixedly connected to the meter 14.

The rotating shaft 10 transmits power to the first gear 18 through the first drive wheel 5 at the upper end, activating the gear transmission chain. The first drive wheel 5 drives the first gear 18, which in turn drives the coaxial second drive wheel 17 to rotate. The second drive wheel 17 meshes with the second gear 19, which drives the third drive wheel 16. The third drive wheel 16 meshes with the third gear 20, which drives the fourth drive wheel 15. The fourth drive wheel 15 meshes with the fourth gear 11, which finally drives the worm gear 12. The worm gear 12 meshes with the turbine 13, changing the horizontal rotation to vertical movement. The turbine 13 is connected to the counter of the meter 14, which converts the number of rotations into a water volume value for display.
[0038] The working principle of the entire device is as follows: When the top of the rotating shaft 10 penetrates the interior of the fitting tube 6, the adjusting plate 212 can be pulled to one side by sliding the adjusting plate 212 and the hollow plate 211, so that the limiting seat can limit the rotating shaft 10. The curved tube 216 can move together with the limiting seat. By using the first ball 213 and the second ball 215 to fit with the rotating shaft 10, water flows into the filter box 1, which drives the impeller 4 to rotate.

[0039] The rotating shaft 10 transmits power to the first gear 18 through the first drive wheel 5 at the upper end. The first drive wheel 5 drives the first gear 18, which in turn drives the coaxial second drive wheel 17 to rotate.
