[0027] Further, such as Figure 1 and Figure 2 As shown, the adjustment component 3 also includes a first motor 32, a threaded rod 33 and a second motor 35. The two first motors 32 are respectively fixed to the two fixing frames 31 by bolts, and the two first motors 32 are symmetrical with the second motor 35 as the axis. The two threaded rods 33 are respectively fixed to the output shafts of the two first motors 32 by bolts, the threaded plate 34 is threadedly connected to the two threaded rods 33, the second motor 35 is fixed to the threaded plate 34 by bolts, and the rotating column 36 is fixed to the output shaft of the second motor 35 by bolts.

[0028] Further, such as Figure 1-Figure 4 As shown, the cleaning component 4 includes a water tank 41, a water inlet pipe 42 and a nozzle 43. The water tank 41 is slidably connected to two fixed frames 31, and two water inlet pipes 42 are fixedly connected to the water tank 41. The two water inlet pipes 42 are symmetrical with the second motor 35 as the axis. A plurality of nozzles 43 are fixedly connected to the water tank 41, and the nozzles 43 are distributed in a circular array on the water tank 41.

[0029] Further, such as Figure 1-Figure 5 As shown, the cleaning assembly 4 also includes a slide plate 44 and a partition plate 45. The two slide plates 44 are respectively threadedly connected to the two threaded rods 33. The two partition plates 45 are respectively fixedly connected to the two slide plates 44. The slide plates 44 are perpendicular to the partition plates 45. The height of the partition plates 45 is greater than the height of the water tank 41. The two partition plates 45 are slidably connected to the water tank 41.

[0030] Further, such as Figure 2-Figure 5 As shown, the cleaning assembly 4 also includes a baffle 46 and a first through hole 47. The baffle 46 is fixedly connected to the two partitions 45. Multiple first through holes 47 are opened on the water tank 41. The first through holes 47 are distributed in a circular array on the water tank 41. One first through hole 47 corresponds to one nozzle 43.

[0031] Further, such as Figure 4 and Figure 5 As shown, the cleaning component 4 also includes a second through hole 48 and a slide groove 49. Multiple second through holes 48 are opened on the baffle 46. The baffle 46 located directly below the water inlet pipe 42 does not have a second through hole 48. When the baffle 46 is located at the top of the inner wall of the water tank 41, the baffle 46 just rests against the water inlet pipe 42. Two slide grooves 49 are opened in the water tank 41, and the two partitions 45 are slidably connected to the two slide grooves 49 respectively.

[0032] The specific working method is: put the flow meter between the two clamping plates 39, then rotate the bidirectional screw 38 to make the two clamping plates 39 move inward, reduce the distance between the two clamping plates 39 to adapt to flow meters of different sizes, and after the flow meter is clamped, start the first motor 32, and its output shaft drives the threaded rod 33 to rotate, and the threaded plate 34 moves down accordingly, driving the flow meter to move down. Since the slide plate 44 is threadedly connected to the threaded rod 33, the slide plate 44 also moves down accordingly, and the partition plate 45 and the baffle plate 46 move down together. At this time, the baffle plate 46 no longer resists the water inlet pipe 42. The water inlet pipe 42 is connected to an external water source to inject water into the water storage tank 41. Due to the downward movement of the baffle plate 46, the baffle plate 46 will block the first Through hole 47, water cannot flow out of the first through hole 47, and the water is stored in the water tank 41. When the flow meter enters the cleaning barrel 2, the second motor 35 is started, and its output shaft drives the rotating column 36 to rotate, and the flow meter rotates accordingly, and is fully in contact with the cleaning liquid in the cleaning barrel 2. After cleaning is completed, the first motor 32 is started to reverse, and its output shaft drives the threaded plate 34 and the slide plate 44 to move upward, and the flow meter moves upward. At this time, the partition 45 and the baffle 46 move upward with the slide plate 44, and the baffle 46 no longer blocks the first through hole 47, so that water flows into the nozzle 43 along the first through hole 47, and is sprayed out from the nozzle 43 to rinse the flow meter for a second time, and clean the residual cleaning liquid thereon, so that the cleaning effect of the device is better.

[0033] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
