Description

Technical Field

[0001] This invention relates to the field of dynamic torque and pressure detection technology, and in particular to a device and method for dynamic detection of torque and pressure in seaweed seedling clamping rope breaking. Background Technology

[0002] Currently, in kelp raft farming, the kelp seedling clamping process is still mainly done manually. Each seedling rope is 2.3-2.5 meters long, with 30-40 kelp seedlings attached to each rope. Manual clamping involves manually applying torque to gradually open the seedling rope, insert the kelp seedling, and tighten the rope. During the clamping season, the weather is cold, the workload is heavy, and the working environment is poor. With the increasing labor shortage, the labor cost for clamping seedlings is rising, and there is an urgent need for mechanized and automated seedling clamping equipment that can replace manual labor. The invention patent application with publication number CN112825763A discloses "a floating rotating eccentric rope clamping method and device", which uses a floating and rotating eccentric rope clamping plug that can pass through the gap of the three strands of the seedling rope.

[0003] Currently, the seedling ropes used in actual production are mainly woven by hand. These seedling ropes are of uneven thickness and have different tensions at different locations. The unevenness of the hand-woven seedling ropes causes randomness when the eccentric rope-breaking plug is inserted into the seedling rope. Some eccentric rope-breaking plugs may become stuck or jammed, leading to rope breaking failure and affecting the stability of the automated kelp seedling clamping operation.

[0004] Currently, there is a lack of a dynamic detection device and method for measuring the torque and pressure when the eccentric rope-breaking plug passes through the gap between the three strands of intertwined seedling rope during the seedling clamping process. Summary of the Invention

[0020] The present invention provides a method for dynamically detecting the torque and pressure of kelp seedling breaking ropes based on the kelp seedling breaking rope dynamic detection device described herein, comprising the following steps:

[0021] S1: After fixing several seedling ropes to be tested on a seedling rope unwinding device, the seedling ropes to be tested are tensioned evenly and at equal intervals inward. The seedling ropes to be tested are unwound. After the seedling ropes are unwound, except for the test section, the non-test sections of the remaining seedling ropes to be tested are inserted into a stainless steel round tube of the same size as the eccentric rope breaking plug as a reference.

[0022] S2: Rotate the second handle to move the unscrewed section of the seedling rope to be tested directly below the eccentric rope break plug, tighten the locking handle, and then turn on the power to the drive motor and adjust the drive motor to the required speed through the speed control motor controller;

Replace the seedling rope to be tested or the eccentric broken rope plug according to the test requirements, and repeat steps S1 to S3 to conduct the next set of tests.

[0025] Because the present invention adopts the above technical solution, it has the following beneficial effects:

[0026] 1. This invention achieves dynamic detection of torque and pressure when the eccentric rope-breaking plug passes through the gap between the three strands of interwoven seedling rope in the kelp seedling clamping process through the coordination of torque measuring components, pressure measuring components, lifting mechanism and horizontal moving mechanism.

The detection device has a simple structure, is easy to operate, and saves time and effort.

[0027] 2. The torque measuring component and the pressure measuring component in this invention are independent of each other. During the test, the relative positions of the two can be freely adjusted according to actual needs. Furthermore, the pressure measuring component has a limiting function under the action of the locking handle on the slider, which avoids the error caused by the left and right shaking of the pressure measuring component during the test.

[0028] 3. The torque sensor and pressure sensor in this invention are connected to the DAQ measurement system on the PC through the force value display controller. The control interface of the DAQ measurement system is simple to operate and facilitates the reading, saving, exporting and analysis of test data, and the test data is reliable.
