As shown in the figure, when a plurality of cable bodies need to be installed, the towing rope bodies are arranged, so that 2, 3, 4 and 6 cable bodies can be installed around the towing rope bodies due to the fact that 12 strip-shaped limiting grooves which are distributed at equal intervals in an annular mode are arranged in the installation area of the towing rope bodies, and the installation distribution is more uniform, so that the gravity distribution is more uniform. The angle of the surrounding ring is adjustable so that adjacent first connection units respectively provide supporting connection for the cable bodies, so that the connection effect is good, and the cable bodies can be prevented from being separated around the towing rope body. As shown in the figure, during installation, the cable body is clamped by the surrounding ring and the sealing plate, the clamping plate can clamp the cable body under the action force of the compression spring, and after the installation is finished, high-pressure gas can be injected into the piston cavity, so that the clamping is further realized.

In addition, between two adjacent towline units, the arc-shaped limiting blocks of each cable body can be placed into two cylinder parts, and the connecting rods are matched with the slots for limiting, so that the cable bodies are further attached to the towline bodies. And the sealing unit seals the two second grooves, so that better sealing is realized for the second air tap. Because gas can be injected into the inner pipe portion layer through the second gas nipple. Due to the heavy weight of the cable body, it will sink in water and the gravitational force of the sink will be great. However, the streamer body of the present application is buoyant in its own right due to the space within the inner tubular section, thereby providing buoyancy to the cable body (but still submerged as a whole), thereby reducing the load when towing the cable, and thus providing more convenient towing. And because the water pressure is great under water, the water pressure can squeeze the towing rope body, so that the towing rope is shrunken (the supporting ring is rigid and cannot be shrunken), and the buoyancy provided by the towing rope is reduced. Through the mode of inflation control atmospheric pressure, can reduce the degree that the towing rope became flat under water to can adjust the buoyancy that the towing rope can provide under water, when the cable body that the towing rope body was attached was many, more gas was filled, when the cable body that the towing rope body was attached was few, only need fill less gas, thereby realize the regulation to the buoyancy of towing rope body. In addition, since the streamer body has a plurality of streamer bodies, the streamer bodies are not communicated with each other. Therefore, even if a certain towing rope body is damaged, the buoyancy can not be provided, and the buoyancy provided by the rest towing rope bodies is not influenced.

As shown in fig. 8, embodiment 3 discloses a towing cable of another structure, which has the same main structure as embodiment 2, and is different from embodiment 2 in that embodiment 3 has 3 cable bodies, and the 3 cable bodies are distributed in an annular equidistant manner. At this time, among the 3 arc-shaped stoppers in the second connection unit, two arc-shaped stoppers are provided with sealing units. The other arc limiting block is not required to be provided with a sealing unit. Since the sum of the thicknesses of the two sealing units is just equal to (or slightly greater than) the distance between the facing end surfaces of the two end blocks, the two sealing blocks are pressed by the two end blocks to just seal the second grooves of the two end blocks.
