The water depth is measured by measuring the length of the rope entering the water. However, this measurement method is prone to bending of the rope due to the influence of water flow and organisms, so the measurement error is large. Utility Model Content

After entering the water, the buoyancy tube 204 rises by buoyancy and the limiting ring 205, so that the buoyancy tube 204 simultaneously sleeves two adjacent bamboo tubes 201, so that the flexible measuring rope mechanism becomes a rigid measuring rope mechanism, avoiding the bending of the measuring rope mechanism due to water flow and plants and animals, and reducing the measurement error.

[0026] The winding mechanism includes a winding roller 301, which is fixedly connected to one end of the flexible measuring rope 100, and the two ends of the winding roller 301 are fixedly connected to a roller shaft 302, and the middle part of the roller shaft 302 is rotatably connected to a bearing seat 303.

[0027] The winding roller 301 is used for winding the rope measuring mechanism, the roller shaft 302 is used for rotationally connecting to the bearing seat 303, and the bearing seat 303 is used for connecting to the winding platform 304.

[0028] The winding mechanism further includes a winding platform 304 , the upper surface of which is fixedly connected to the bearing seat 303 , and a motor 305 is disposed on the upper surface of the winding platform 304 , the output shaft of which is fixedly connected to the roller shaft 302 .

[0029] The winding platform 304 is used to install the bearing seat 303 and the motor 305 . The motor 305 provides a rotational power to drive the roller shaft 302 and the winding roller 301 to rotate, so that the rope measuring mechanism is wound on the winding roller 301 .

[0030] The limiting mechanism includes a transverse slide groove 401, which is arranged on the front side of the winding platform 304. The transverse slide groove 401 is slidably connected to a transverse slider 402.

[0036] Working principle:

[0037] Start the motor 305 to gradually put the rope measuring mechanism into the water. The gravity of the bamboo tube 201 in the rope measuring mechanism is greater than the buoyancy, and the bamboo tube 201 sinks. The buoyancy of the buoyancy tube 204 is greater than the gravity, so the buoyancy tube 204 moves upward under the action of buoyancy. At the same time, since the limit ring 205 is restricted between the two bamboo tubes 201, the two ends of the buoyancy tube 204 are connected to the two adjacent bamboo tubes 201, so that the rope measuring mechanism becomes rigid after entering the water, avoiding bending due to the influence of water flow and organisms, thereby reducing measurement errors.

[0038] Start the motor 305. The rotation of the motor 305 drives the rotation of the roller 302. The roller 302 drives the rotation of the winding roller 301 to wind up the flexible measuring rope 100 and the rope measuring mechanism. At the same time, the electric telescopic rod 404 is used to control the horizontal position adjustment of the ring 403, so that the flexible measuring rope 100 and the rope measuring mechanism are driven to wind around the corresponding position of the winding roller 301 during winding to avoid winding disorder.
