[0033] The right side of first runner 701 and second runner 702 is fixedly connected with moving rod 704, the left side of second runner 702 and third runner 703 is provided with moving groove 705, moving rod 704 is movably installed in the inside of moving groove 705, moving rod 704 and moving groove 705 cooperate with each other, and power transmission and decimal counting between first runner 701, second runner 702 and third runner 703 are realized.

[0034] The outer wall of second runner 702 is provided with movable groove 706 on both sides, a plurality of ring-shaped distributed rollers 707 are movably installed in movable groove 706, the setting of movable groove 706 and roller 707 reduces the friction between the runners, and the rotation of the runner is more smooth.

[0035] The roller 707 close to the third rotating wheel 703 is attached to the left side of the third rotating wheel 703, and the roller 707 close to the first rotating wheel 701 is attached to the right side of the first rotating wheel 701, which enhances the stability of power transmission between the rotating wheels and ensures the accuracy of display.

[0036] The outer wall of the first rotating wheel 701, the second rotating wheel 702 and the third rotating wheel 703 is fixedly installed with a number block 708, which has ten annular distributions. The number block 708 is used to visually display the water level value, which is convenient for users to read.

[0037] The outer wall of the shell 1 is fixedly installed with a protective cover 6, and the display assembly 7 is located in the interior of the protective cover 6. The outer wall of the protective cover 6 is provided with an observation port, and the observation port is inlaidly installed with an observation glass 601.

[0040] Working principle: first, fix the shell 1 in the water body whose water level needs to be monitored, so as to keep it vertical. When the water level changes, the float ball 3 will move up and down with the rise and fall of the water level. Since the float ball 3 is fixed at the bottom of the rack 2, the movement of the float ball 3 will drive the rack 2 to slide up and down in the interior of the shell 1.

[0041] The up and down movement of the rack 2 will interact with the gear 4. Since the rack 2 and the gear 4 are intermeshed, the linear motion of the rack 2 is converted into the rotation of the gear 4. When the gear 4 rotates, the first bevel gear 5 fixedly connected to the outer wall of the gear 4 will also rotate. The first bevel gear 5 and the second bevel gear 8 fixedly connected to the outer wall of the first rotating wheel 701 are intermeshed. The rotation of the first bevel gear 5 drives the rotation of the second bevel gear 8, which in turn makes the first rotating wheel 701 start to rotate.

[0042] When the first rotating wheel 701 rotates, the right fixedly connected moving rod 704 will move in the moving groove 705 on the left side of the second rotating wheel 702, when the first rotating wheel 701 rotates one circle, the moving rod 704 will drive the second rotating wheel 702 to rotate a certain angle, by the same token, when the second rotating wheel 702 rotates, the moving rod 704 on the right side will move in the moving groove 705 on the left side of the third rotating wheel 703, when the second rotating wheel 702 rotates one circle, it will drive the third rotating wheel 703 to rotate a little, realizing the decimal counting.

[0043] Due to the number blocks 708 on the outer wall of the first rotating wheel 701, the second rotating wheel 702 and the third rotating wheel 703, with the rotation of the rotating wheels, the number blocks 708 will also rotate, the user can directly see the displayed water level value through the observation glass 601 in the observation opening on the outer wall of the protective cover 6.

[0044] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
