Description

Technical Field

[0001] This utility model relates to the field of marine exploration technology, and in particular to an underwater exploration cable laying device with automatic tensioning function. Background Technology

[0002] Deploying exploration cables into the ocean can be used for marine geological and resource exploration. The cables can transmit electrical signals or receive data such as seismic waves to analyze the distribution and properties of seabed rock layers and sediments, understand seabed geological structures such as faults and folds, and detect the location and reserves of resources such as oil, natural gas and minerals, providing a basis for marine resource development.

[0003] Existing exploration cable laying devices cannot automatically adjust the tension of the exploration cable during the laying process. This can cause the cable to become loose or tangled due to insufficient tension, or to be overstretched or even break due to excessive tension. Utility Model Content

[0004] In order to solve the above-mentioned technical problems in the prior art, the present invention provides an underwater exploration cable laying device with automatic tensioning function.

[0005] The underwater exploration cable laying device with automatic tensioning function provided by this utility model adopts the following technical solution:

[0012] Furthermore, a U-shaped seat is fixedly connected to the bottom of the slide plate, and a tensioning wheel for controlling the tension of the exploration cable is rotatably installed at the center of the U-shaped seat.

[0013] In summary, the beneficial effects of this utility model are as follows:

[0014] This invention features an automatic tensioning mechanism. During cable laying, a tension sensor on the tensioning wheel monitors the tension of the exploration cable in real time.

[0025] Reference Figure 1 As shown, a third bracket 6 is fixedly installed on the surface of the fixed frame 1 by bolts. The third bracket 6 is located between the first support frame 2 and the second bracket 51. An automatic tensioning mechanism 7 for controlling the tension of the exploration cable is provided on the upper part of the third bracket 6. The tension of the exploration cable is automatically adjusted by pressing the upper wall of the exploration cable through the automatic tensioning mechanism 7.

[0026] As a preferred option, refer to Figure 2 and Figure 5As shown, the automatic tensioning mechanism 7 includes a fixed plate 71 and an adjusting plate 73. An L-shaped support plate 61 is located on the top of the third bracket 6. The fixed plate 71 is fixedly welded to the end of the L-shaped support plate 61. An upper motor 72 is fixedly installed on the surface of the fixed plate 71 near the L-shaped support plate 61. The adjusting plate 73 is rotatably located on the side of the fixed plate 71 away from the L-shaped support plate 61. The drive shaft of the upper motor 72 passes through the fixed plate 71 and is fixedly connected to the adjusting plate 73. In use, the upper motor 72 drives the adjusting plate 73 to rotate. A slide rail 74 is located on the side of the fixed plate 71 away from the upper motor 72. The slide rail 74 is located at the bottom of the fixed plate 71 and has a sliding mechanism inside. The slide rail 74 has a sliding plate 75, with a sliding pin protruding outward from the side of the sliding plate 75. A guide hole 731 is provided on the surface of the adjusting plate 73.

The motor 4 is started to rotate the drum 3 to release the cable. During the release process, the tension sensor on the tension wheel 77 monitors the tension of the exploration cable in real time. The upper motor 72 operates according to the detection results of the tension sensor. The upper motor 72 drives the adjustment disc 73 to rotate, and drives the slide plate 75 to move downward or upward through the guide hole 731 in the adjustment disc 73. This causes the tension wheel 77 to press the exploration cable downward or loosen it upward, thereby achieving automatic adjustment of the tension of the exploration cable during the release process. This ensures that the exploration cable maintains appropriate tension during the release process, avoiding situations where the cable becomes loose or tangled due to insufficient tension, or where the cable is overstretched or even breaks due to excessive tension.
