In the first use process, the driving unit 200 drives the protection unit 300 to rotate by double driving, so as to relieve the protection effect of the protection unit 300 on the internal structure of the protection box 101, specifically, when the water surface stably rises and synchronously drives the first floating unit 201 and the second floating unit 202 to drive, the first floating plate 201c vertically rises along the first limiting pipe 201a, the first vertical rack 201d drives the first slider 201h to rise and drive the first gear 201i to rotate, in the rising process of the first slider 201h, one side inclined plane of the first slider 201h is extruded by the first fixed column 201e, the other side inclined plane of the first slider 201h drives the first movable column 201f to horizontally move along the first limiting pipe 201a, the first spring 201g contracts, the first movable column 201f horizontally moves to drive the first special-shaped block 309b to horizontally move along the upper surface of the mounting platform 102, the first horizontal plate 311b moves horizontally near the third gear 306 under the cooperation of the second limiting pipe 202a and the first extrusion rod, so that the first rack 311e is meshed with the third gear 306, and meanwhile, the second rack 311f is meshed with the second gear 202i, on the other hand, the second floating plate 202c vertically ascends along the second limiting pipe 202a, the second vertical rack 202d drives the second sliding block 202h to ascend and drive the second gear 202i to rotate, in the ascending process of the second sliding block 202h, one side inclined surface of the second sliding block 202h is extruded by the second fixed column 202e, the second movable column 202f is driven by the other side inclined surface of the second sliding block 202h to move horizontally along the second limiting pipe 202a, the second spring 202g contracts, the second movable column 202f moves horizontally to drive the second special-shaped block 310b to move horizontally along the upper surface of the mounting platform 102, the second horizontal plate 312b moves horizontally near the third gear 306 under the cooperation of the first limiting pipe 201a and the second extrusion rod, the engagement of the third rack 312e and the third gear 306 is realized, the fourth rack 312f is engaged with the first gear 201i, under the rotation of the first gear 201i and the second gear 202i, the first rack 311e and the third rack 312e perform the same-speed but opposite horizontal movement, so that the third gear 306 rotates, the third gear 306 rotates to drive the rotating plate 301 to rotate, the two arc grooves 302 are synchronously driven to rotate, the two moving columns 303 move along the two arc grooves 302, the two moving plates 305 perform the horizontal movement under the limit of the two fixed plates 304, and the protection effect of the protection unit 300 on the internal structure of the protection box 101 is relieved;
In the second use process, the protection unit 300 rotates to synchronously drive the limiting unit 400 to release the limiting effect on the rotating shaft 503, the automatic measurement of the water level by the measurement unit 500 is triggered, specifically, the rotating plate 301 rotates to enable the two moving plates 305 to horizontally move under the limit of the two fixed plates 304, the two limiting risers 401 are synchronously driven to horizontally move to be separated from two ends of the rotating shaft 503, and the measurement unit 500 is separated from the protection box 101 under the self weight of the measurement probe 505 and penetrates through the installation platform 102 to automatically measure the water level.
In summary, the water level measuring device of the invention has the advantages that daily collection work of operation and maintenance personnel on water level can be reduced, and when the water level is not stable (stormy waves and the like) and rises to the alarm water level, measurement operation does not occur, and only when the water level is stably risen to the alarm water level, the driving unit 200 is driven to perform double driving, the protection effect of the protection unit 300 on the internal structure of the protection box 101 and the limit effect of the limit unit 400 on the measurement unit can be simultaneously released, and the measurement operation is automatically triggered.
It should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered in the scope of the claims of the present invention.
