[0024] 1. In the present invention, the plasma cutting equipment for producing marine cold storage is described. By lifting the adjustment plate upward, the parts for producing marine cold storage are placed on two L-shaped supporting plates, and then the pull ring is pulled to drive the square plate and the positioning plate to move horizontally, so that the positioning plate is separated from the positioning groove, and the fixation of the turntable is released. Then, the turntable is rotated to drive the bidirectional screw to rotate. The bidirectional screw drives the two beams to move horizontally through the thread transmission with the two beams and under the guidance of the fixed rod and the cross bar, and drives the two L-shaped supporting plates to move horizontally through the corresponding vertical plates, so that the square plate and the positioning plate can be adjusted according to the rotation of the square plate. The length of the workpiece adjusts the distance between the two L-shaped support plates. After adjusting to a suitable distance, loosen the turntable and the pull ring, so that the square plate moves in the opposite direction under the elastic force of the connecting spring, and drives the positioning plate to be clamped into the positioning groove to lock the turntable. Then rotate the knob to drive the fastening screw to rotate. The fastening screw drives the pressure plate to move downward through the threaded transmission with the threaded hole. The workpiece is fixed by the cooperation of the pressure plate and the L-shaped support plate. Then loosen the adjustment plate, so that the adjustment plate moves downward under the elastic force of the reset spring, and the ball contacts the surface of the workpiece.

[0025] 2. In the present invention, a plasma cutting device for producing a marine cold storage is described. By starting a plasma cutting gun, a plasma arc is emitted to cut a workpiece, and a first drive motor and a second drive motor are started.

The second drive motor drives the second screw rod to rotate, and the second screw rod drives the plasma cutting gun to move horizontally through a threaded transmission with the mounting plate, thereby achieving cutting of different positions of the workpiece. During the movement of the plasma cutting gun, the ball is kept in contact with the workpiece under the elastic force of the return spring. When the ball moves to a thicker area of ​​the workpiece, the ball moves upward therewith, and drives the slide plate and the conductive frame to move upward through the vertical rod, so that the resistance of the part of the resistor bar above the conductive frame is reduced, and the resistance of the part below the conductive block is increased. The resistance increases, thereby reducing the current of the first drive motor and the second drive motor, thereby reducing the speed of the plasma cutting gun, and at the same time increasing the current in the circuit of the plasma cutting gun, and increasing the working power of the plasma cutting gun to ensure the cutting effect on the thicker part of the workpiece. At the same time, the vertical rod will drive the adjustment plate to move upward during the upward movement, and the adjustment plate will drive the sliding frame to move upward. The sliding frame drives the connecting column to move upward through the connecting rod. The connecting column moves to the left along the inclined hole during the upward movement, and then drives the sliding frame to move to the left. The sliding frame drives the roller to move to the left through the bracket. When the thickness of the workpiece reaches a certain degree, the roller will contact the trapezoidal plate, and push the mounting seat downward through the contact with the trapezoidal plate. The mounting seat drives the plasma cutting gun downward, so that the plasma cutting gun is close to the workpiece, thereby improving the cutting effect on thick workpieces.

[0026] 3. In the present invention, the plasma cutting equipment for producing a marine cold storage starts the vacuum pump to generate suction to extract the smoke generated by the plasma cutting, and introduces the smoke into the purification frame, and filters and purifies the smoke through the filter element;
