However, this not only takes a lot of time, but also has high labor intensity and high safety risks. In addition, as the water depth increases, it is difficult for underwater workers to reach the operation area, which greatly affects the efficiency of underwater cutting operations. At the same time, underwater operations are difficult, and the complex underwater conditions can easily affect underwater workers, causing uncontrollable factors, affecting the cutting quality, and resulting in low cutting accuracy.

The bottom of the clamping claw 37 is provided with an arc-shaped groove 39. The positive and negative threaded screw 35 is controlled to rotate by the screw motor 34, so as to control the screw sliders 36 at both ends to move toward each other along the positive and negative threaded screw 35, so as to control the clamping claw 37 to clamp or release the piece 6 to be cut.

[0054] like Figures 1 to 5As shown, a cutting method for underwater cutting saw of the present invention comprises the following steps:

[0055] a. Preparation before cutting

[0056] First, the machine body 1 is put into the water, and the main driving member 14 in the driving assembly controls the machine body 1 to move forward underwater, and then the lifting driving member 15 cooperates with the direction adjustment driving member 16 to control the machine body 1 to move to the top of the to-be-cut part of the to-be-cut piece 6;

[0057] b. The swing assembly in the underwater support adjustment mechanism 5 controls the support frame 2 to rotate so that the support frame 2 flips downward;

[0058] c. Fixed

[0059] The fastening assembly 3 at the bottom of the adjustment mechanism 5 is running, and the screw motor 34 controls the rotation of the positive and negative screws 35, so that the sliders at both ends of the positive and negative screws 35 run towards each other, thereby driving the claws 37 to clamp on the outer wall of the cutting piece;

[0060] d. Cutting

[0061] 1) Swing cutting

[0062] First, the cutting saw 27 is controlled to run, and at the same time, the swing motor 31 in the adjustment member controls the cutting saw 27 to swing downward, so that the cutting saw 27 cuts the band cutting member;

[0063] 2) Slip cutting

[0064] When it is necessary to cut the cutting piece multiple times, after the current cutting is completed, the cutting saw 27 stops running, and the fastening component 3 releases the piece to be cut 6, the driving component controls the body 1 to move to the next cutting position, the fastening component 3 is clamped again, and the cutting saw 27 runs at the same time, and the sliding seat 30 drives the cutting saw 27 to move along the direction of the guide rod 29, thereby controlling the cutting saw 27 to cut again, repeating the operation multiple times to complete the cutting.

[0065] The present invention provides a support frame 2, an adjustment mechanism 5 is provided between the two support frames 2, a cutting mechanism 4 is provided at the front end of the adjustment mechanism 5, and a fastening assembly 3 is provided at the bottom of the adjustment mechanism 5. The machine body 1 is controlled to move underwater through the adjustment mechanism 5. At the same time, during the underwater cutting process, the adjustment mechanism 5 first controls the support frame 2 to flip downward, and then the fastening assembly 3 clamps and fixes the to-be-cut piece 6, thereby increasing the stability of the cutting process. The to-be-cut piece 6 is then cut by the cutting mechanism 4. When moving underwater, the support frame 2 flips upward, thereby reducing the resistance of the machine body 1 moving underwater and improving the smoothness of the machine body 1 moving underwater. When cutting, the support frame 2 flips downward, so that the support frames 2 on both sides protect the cutting of the cutting mechanism 4. At the same time, when at the bottom of water, the support frame 2 is supported at the bottom of water to stabilize the machine body 1.

[0066] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
