[0031] Specifically, by moving the sensor body 5, i.e., the limit sensor, to the lower part of the ship winch, the complex movable sensing frame is replaced by the gravity sensing block 6, and the elbow pipe is lifted upward to lift the gravity sensing block 6. The sensor body 5 detects the gravity sensing block 6 to obtain the upper limit. When the elbow pipe is lowered, the gravity sensing block 6 is separated from the sensor by its own gravity, reducing the distance between the sensor and the sensor, making the sensing sensitive, reducing and eliminating the phenomenon that the sensor cannot be sensed and stuck, reducing the time for personnel to check and repair on site, increasing the time utilization rate, increasing the dredging time, and canceling the personnel arrangement for special on-site processing, improving the labor utilization efficiency and reducing the labor cost. By setting the lifting assembly, the sensor body 5 arranged at a high place can be easily lifted from a low place, facilitating the maintenance of the sensor body 5 in the later period, reducing the danger of workers climbing, and stably installing the sensor body 5 lifted to a high place in the ship with the positioning assembly, improving the stability of the sensor body 5 installation.
