The lower shell 1 and the upper shell 2 form a whole. The winding roller 5 rotating inside the lower shell 1 winds multiple turns of the measuring rope 6. The bottom sinker 8 at the bottom of the measuring rope 6 is counterweighted, so that the bottom sinker 8 drives the measuring rope 6 to fall to the river bottom for vertical water depth measurement. During measurement, a conical stop plate 13 is connected inside the outlet drum 3, and a floating ball 14 is placed on the stop plate 13. When the outlet drum 3 is not put into the water body, the floating ball 14 is stuck at the bottom of the stop plate 13, the measuring rope 6 is blocked, and the bottom sinker 8 is placed to fall. The upper end of the upper shell 2 is connected to the hanging rope 18 through the hanging ring 17, and the hanging rope 18 is connected to the rod body. The device is placed vertically on the upper end of the water body at the measuring point through the rod body. The lower shell 1 is suspended as a whole through the floating ring 4. The outlet drum 3 is immersed in the water body, and the floating ball 14 floats up through the water body to release the device. The measuring rope 6 is stuck, and the wound measuring rope 6 is allowed to measure the water body. After the measurement is completed, when the device is lifted, the float 14 falls again and is stuck at the bottom of the stopping plate 13, and the measuring rope 6 after the water depth measurement is stuck. The marking ring 7 inside the measuring rope 6 is used to mark the depth, so that the device can vertically measure the water depth of the corresponding point without pulling and offset. The water depth of the corresponding position of the water body is accurately measured, the measurement is accurate, and the operation is convenient. After the measurement is completed, the measuring rope 6 is wound up by the winding device and reused, and the use effect is good.

[0024] Preferably, Figure 2 As shown, the wire outlet drum 3 is arranged in the middle position of the lower shell body 1, and the wire outlet drum 3 is arranged directly below the winding roller 5. The wire outlet drum 3 in the middle of the bottom end of the lower shell body 1 allows the wire to be output from the middle of the device, and the winding roller 5 directly below the wire outlet drum 3 allows the measuring rope 6 to fall smoothly, so that the measuring rope 6 falls stably.

[0025] Preferably, Figure 2 As shown, the upper end of the outlet drum 3 is connected with a blocking rod 15, and the measuring rope 6 passes through the middle of the blocking rod 15. The blocking rod 15 at the upper end of the outlet drum 3 limits the upper end of the measuring rope 6, so that the measuring rope 6 falls stably.

[0026] Preferably, Figure 2As shown, the blocking rod 15 is arranged in the middle position of the outlet cylinder 3, and the gap between the blocking rod 15 and the outlet cylinder 3 is smaller than the diameter of the float 14. The blocking rod 15 cooperates with the outlet cylinder 3 to block the float 14 to prevent the float 14 from escaping from the cylinder 3.

A second bevel gear 11 is welded to the bottom of the rotating rod 10. A spring 12 is connected to the rotating rod 10. The other end of the spring 12 is connected to the outer wall of the upper shell 2. The upper shell 2 performs vertical limiting installation of the rotating rod 10. The spring 12 on the rotating rod 10 provides elastic force to allow the rotating rod 10 to move vertically upward when not in use, so that the second bevel gear 11 is separated from the first bevel gear 9 to avoid affecting the rotation of the winding roller 5. When winding is needed, the rotating rod 10 is pressed down to allow the first bevel gear 9 to match and mesh with the second bevel gear 11.

The device is suspended as a whole through the floating ring 4, the outlet reel 3 is immersed in the water body, and the float 14 floats up through the water body, releasing the jam of the measuring rope 6, allowing the wound measuring rope 6 to measure the water body. After the measurement is completed, when the device is lifted, the float 14 falls down again and is jammed at the bottom of the stop plate 13, and the measuring rope 6 after the water depth measurement is locked. The marking ring 7 inside the measuring rope 6 is used to mark the depth, so that the device can vertically measure the water depth of the corresponding point without pulling and offset. The water depth of the corresponding position of the water body is accurately measured, the measurement is accurate, and the operation is convenient. After the measurement is completed, the measuring rope 6 is wound up by the winding device and reused, and the use effect is good.
