Installation card frame 701 accessible two sets of fixed knobs 702 are fixed at work bench or ship limit, make things convenient for the use of this water gauge, accessible rotation control barre 603 drives installation section of thick bamboo 101 motion, cooperation level bar 102 is adjusted the angle of installation section of thick bamboo 101, and then improve measurement accuracy, connecting sleeve 602 can follow the motion of connecting rod 606, and then conveniently finely tune measuring position, locating piece 608 card is established in location spout 605, make and drive connecting rod 606 when rotating connecting sleeve 602 and rotate, snap ring 704 carries out simple and easy fixing with cardboard 607 through frictional force, and then fix the angle of connecting sleeve 602.

The specific use mode and function of the embodiment are as follows:

the water gauge can be fixed on a shoreside workbench or an eave to measure the water level through the mounting clamp frame 701 in the using process, the control handle rod 603 can be matched with the water gauge 102 to adjust the water gauge body 201 in the measuring process to enable the water gauge body to be perpendicular to the water surface, the measuring accuracy is improved, the connecting plate 601 can be detached through four groups of bolts, the water gauge can be used through the handle 105 after being detached, and the water gauge is suitable for various measuring environments; through pressing two sets of fixed pins 305 on the fixed awl 301 and making it break away from second mounting hole 204, alright rotate screw thread post 303 to conveniently change fixed awl 301, prevent that fixed awl 301 from using for a long time and can't change the back and receive the erosion damage of water and lead to fixing firmly inadequately to this water gauge.

After the hydrological ruler is vertically adjusted, the transmission motor 403 is controlled to rotate to drive the screw rod 401 to move, the screw rod 401 drives the thread moving seat 501 to move along the positioning clamp column 103, the thread moving seat 501 drives the clamping frame 503 to move in the moving process, two groups of clamping plates 505 on the clamping frame 503 drive the hydrological ruler body 201 to move downwards through the friction pads 506, the supporting plate 302 at the bottom of the hydrological ruler body 201 is adjusted to be level with the water surface, so that measurement is started, the hydrological ruler body 201 drives the ruler tape 407 to be elongated in the downwards moving process, a worker can know the water depth through the reading of the ruler tape 407 in the reading groove 108, when the supporting plate 302 at the bottom of the hydrological ruler body 201 moves to the underwater ground, the fixing cone 301 penetrates through the ground to fix the hydrological ruler body 201, the measurement precision is prevented from being influenced by the water flow rate, the reading and the measurement of the hydrological ruler are very convenient, and the working efficiency and the measurement precision are effectively improved, is worthy of popularization and application.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
