[0023] It should be noted that: by rotating the six-prism twist block 18, the rotating shaft 16 and the gear 17 can be driven to rotate, the meshing transmission of the gear 17 and the rack 13 can convert the rotary motion into the vertical linear motion of the rack 13, and then drive the two scraping rings 5 connected by the connecting plate 6 to slide up and down along the measuring rod 2. The operator does not need to directly contact the measuring rod 2, and can conveniently control the reciprocating motion of the scraping ring 5, so as to scrape off the dirt attached to the surface of the measuring rod 2 and the scale line 21, effectively solve the problem that the underwater part of the traditional measuring rod 2 is inconvenient to wipe manually and needs to be removed for maintenance, and significantly improve the maintenance efficiency and the long-term reliability of the measurement data.

[0024] Reference Figure 3 As shown, the positioning mechanism includes a locking disc 19 and a locking bolt 20, and the locking disc 19 is fixedly sleeved on the rotating shaft 16. One of the two shelf plates 15 is threadedly connected with two locking bolts 20 arranged in parallel, and the end of the locking bolt 20 abuts against the locking disc 19. The side of the locking disc 19 close to the locking bolt 20 is provided with an anti-skid pattern.

[0025] It should be noted that: when the scraping ring 5 moves to the specified position, the two locking bolts 20 are tightened, and the ends thereof are tightly pressed against the anti-skid pattern surface of the locking disc 19, so that the strong friction force can prevent the rotating shaft 16 from accidentally rotating, thereby realizing reliable mechanical locking of the position of the entire cleaning mechanism.

[0026] Reference Figure 1 And Figure 2 As shown, the upper surface of the top plate 1 is fixedly connected with a protective cover 7, the front end surface of the protective cover 7 is provided with a sealing door 8, the sliding rod 14 is sleeved with a first sealing ring 12 located between the connecting column 11 and the top plate 1, and the rack 13 is sleeved with a second sealing ring 10 located between the connecting block 9 and the top plate 1. The top end of the connecting column 11 and the top end of the connecting block 9 are located on the same horizontal plane.

[0027] It should be noted that: the protective cover 7 provides physical protection for the precise transmission components such as the gear 17, the upper part of the rack 13, and the locking mechanism, so as to avoid direct intrusion of external dust, water splashing or foreign matters. The first sealing ring 12 and the second sealing ring 10 constitute an important dynamic sealing structure. Since the top ends of the connecting column 11 and the connecting block 9 are flat, when the connecting plate 6 moves upward, the first sealing ring 12 and the second sealing ring 10 can be synchronously extruded by the connecting column 11 and the connecting block 9, and positioned by the positioning mechanism. The sliding rod 14 and the rack 13 can effectively seal the movement gap when passing through the top plate 1, significantly improve the dustproof, moistureproof and corrosion-resistant performance of the device, and prolong the service life of the device in harsh environments near water.

[0029] Reference Figure 1 As shown, the upper and lower end faces of the scraping ring 5 are provided with inclined chamfers, which help to guide and reduce the accumulation of dirt on the ring opening edge when the scraping ring 5 moves up and down, reduce the movement resistance, make the scraping action more smooth, and also help the scraped dirt to be smoothly discharged, avoid secondary attachment, and further improve the cleaning effect.

[0030] The working principle of the utility model is as follows: in use, the device is stably installed in the water to be measured through the insertion rod 4, and the water level height is directly read by observing the position of the water surface on the scale line 21 of the measuring rod 2; when the scale line 21 on the surface of the measuring rod 2 is blurred due to the attachment of dirt, the sealing door 8 of the protective cover 7 is opened, the locking bolt 20 is loosened, then the hexagonal knob 18 is rotated, the gear 17 drives the rack 13, and then the two scraping rings 5 are driven to slide up and down along the measuring rod 2 through the connecting plate 6, so that the dirt is scraped off and the scale is clear; after cleaning, the hexagonal knob 18 is rotated to move the rack 13 upwards, the first sealing ring 12 and the second sealing ring 10 are squeezed, then the locking bolt 20 is tightened to lock the position, and the protective cover 7 and the first sealing ring 12 and the second sealing ring 10 provide continuous protection for the internal mechanism.

[0031] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion or direct or indirect application in other related technical fields by using the contents of the utility model specification and drawings is also included in the patent protection range of the utility model.
