The small end of the first connecting rod 25 and the large end of the second connecting rod 25 can be connected and fixed by inserting a pin into the pin hole.

[0028] Working principle: When the device is not working, two sets of hydraulic telescopic rods 6 can be started to operate. The upper folding frame 8 can be pulled by the hydraulic telescopic rods 6 to rotate and fold, so that the device can be folded and placed to reduce the occupied volume. The rollers 2 at the bottom can be used to move the device to a suitable position for storage. When the device is working, the upper folding frame 8 is pushed open by the hydraulic telescopic rods 6, and the legs 11 are unfolded to fix it, which can stabilize the device. The device can be hoisted to a height of 4 meters and the lifting weight is greater than 200 kg.

[0029] When the product is tested, the product is first hoisted to the highest height to make it vertical, and then the crane 9 lowers the product to the exit of the clamping mechanism 10, and the clamping cylinder A20 is started to drive the two sets of fixed grippers 19 to approach each other to clamp the product head;

[0030] After the product enters the water, the connecting rod 25 is hoisted by the crane 9, and the small end of the connecting rod 25 is connected to the connecting head of the product at the gripping mechanism 10, and then the connecting rod 25 is lowered. At this time, the product is put into the water to a depth of one connecting rod 25, and then the crane is controlled to lower the first connecting rod 25 and the product together to the gripping mechanism 10, and then the gripping mechanism 10 is moved to a suitable position to clamp and fix the large end of the first connecting rod 25. In addition, the safety ring at the head of the connecting rod 25 can also prevent the gripper of the fixing device from not gripping the large end of the connecting rod 25, causing the product to fall;

[0031] In the same way, connect the small end of the second connecting rod 25 to the large end of the first connecting rod 25. The small end of the first connecting rod 25 and the large end of the second connecting rod 25 are connected and fixed with a pin, and the above steps are repeated until the product is delivered to the specified depth;

[0032] After the product reaches the target depth, in order to control the orientation of the product in water, the fixed gripper 19 on the rotating mechanism 7 is used to clamp the head of the connecting rod 25, and the orientation of the product is controlled by controlling the rotation angle of the rotating platform.
