These equipment play an important role in the fields of marine scientific research, geology, petroleum resource exploration, environmental monitoring, etc. The cable dragging device of geophysical exploration equipment is widely used in marine scientific research for dragging the cable of geophysical exploration equipment on the sea surface.
[0003] Regarding the existing related technologies, the inventor believes that there are the following defects: when a general hull directly drags geophysical exploration equipment, when the distance between the equipment and the hull is too close, the equipment will collide and rub against the hull, thereby causing damage to the geophysical exploration equipment. Content of the Utility Model

[0018] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.
[0019] Embodiment 1: Please refer to Figure 1 - Figure 4, An extended extension device based on the cable dragging of geophysical survey equipment in this embodiment includes a hull 1 and a fixed cylinder 2. Two connecting seats 6 are fixedly connected to one side of the hull 1. One side of the connecting seat 6 is fixedly connected to the outside of the fixed cylinder 2. A plugging rod 3 is pluggably connected to the inside of the fixed cylinder 2. One end of the plugging rod 3 is fixedly connected to a dragging rod 4. One end of the dragging rod 4 is fixedly connected to a fixing ring 5. One side of the fixed cylinder 2 is hingedly connected to a support rod 7. One end of the support rod 7 is hingedly connected to the bottom of the dragging rod 4;
[0020] Among them, generally, the fixed cylinder 2 is fixedly installed on one side of the connecting seat 6, and the connecting seat 6 is fixedly installed on the outside of the hull 1. When the hull 1 moves, the fixed cylinder 2 is driven to move through the connecting seat 6. The fixed cylinder 2 will drive the plugging rod 3 inside to move, the plugging rod 3 will drive the dragging rod 4 to move, and the dragging rod 4 will drive the fixing ring 5 to move. When it is necessary to drag the geophysical survey equipment, the connecting cable of the equipment is fixedly tied to the fixing ring 5. The fixing ring 5 will drive the geophysical survey equipment to move through the cable. At the same time, dragging through the dragging rod 4 can prevent the equipment from approaching the hull. Generally, when dragging the equipment, the direction of the dragging rod 4 is perpendicular to that of the hull 1;
[0021] Furthermore, a first hinge seat 8 is fixedly connected to the outside of the fixed cylinder 2. One end of the support rod 7 is hingedly connected to the inside of the first hinge seat 8. One end of the support rod 7 moves horizontally around the inside of the first hinge seat 8. A second hinge seat 9 is fixedly connected to the bottom of the dragging rod 4. The other end of the support rod 7 is hingedly connected to the inside of the second hinge seat 9;
[0022] Among them, the plugging rod 3 can rotate around the inside of the fixed cylinder 2, so that the plugging rod 3 drives the dragging rod 4 to rotate around the fixed cylinder 2. One end of the support rod 7 will rotate around the inside of the first hinge seat 8. Thus, by rotating the plugging rod 3 and the dragging rod 4, one end of the dragging rod 4 can drive the fixing ring 5 to approach one side of the hull. The fixing ring 5 will drive the geophysical survey equipment to rotate through the cable, making the equipment approach the hull and facilitating the picking and placing of the equipment;
[0023] Furthermore, a bolt 10 is arranged on the outside of the fixed cylinder 2. One end of the bolt 10 is threadedly connected to the inside of the fixed cylinder 2. One end of the bolt 10 is located inside the fixed cylinder 2. One end of the bolt 10 is in contact with the outside of the plugging rod 3. By setting the bolt 10, by rotating the bolt 10, one end of the bolt 10 can be in contact with and lock the outside of the plugging rod 3, thereby preventing the dragging rod 4 from rotating when dragging the cable;
[0024] Furthermore, the fixing cylinder 2, the dragging rod 4, and the supporting rod 7 form a triangular structure. By providing the supporting rod 7, the fixing cylinder 2, the dragging rod 4, and the supporting rod 7 form a triangular stable structure, which can provide support for one end of the dragging rod 4 and prevent the dragging rod 4 from breaking due to excessive length.
[0025] Working principle: Fix the connecting cable of the device to the fixing ring 5 by tying. Then, when the hull 1 moves, the hull 1 will drive the connecting seat 6 and the fixing cylinder 2 to move. The fixing cylinder 2 will drive the inserted rod 3 to move. The inserted rod 3 will drive the dragging rod 4 to move. The dragging rod 4 will drive the fixing ring 5 to move. The fixing ring 5 will drive the geophysical survey device to move through the cable. Thus, dragging through the dragging rod 4 can prevent the device from colliding with the hull.
[0026] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
