The cable retracting motor 126 is connected to the air compressor 125 and the gun control room 13. The device room 123 can also accommodate other required devices, which can be selected by the user according to the needs. The cable retracting motor 126 is connected to a tow rope 5. The gun sled 3 and the compartment 122 are separated by a matching pulley 127 and the connection between the aft deck space 12 and the partition. The towing rope 5 is wound around the matching pulley 127. The towing rope 5 is detachably connected and fixed to the gun sled 3. Therefore, the towing rope 5 can be smoothly dragged by utilizing the setting of the matching pulley 127. The setting of the towing rope 5 can facilitate the dragging of the gun sled 3 and the floating boat 2 along the resistance reduction guide device 11 to climb into the compartment 122 of the aft deck space 12, thereby improving the storage efficiency of the gun sled 3 and the floating boat 2.

[0089] Furthermore, the two side edges of the drag reduction guide device 11 may respectively have a lifting ear 111, and the end of the aft deck space 12 may be erected with two support rods 128 fixed with a steel cable fixed pulley connecting the retracting device 129. When the drag reduction guide device 11 is lowered during exploration, the lifting ears 111 are respectively bound to one end of a pull rope 120, and the pull rope 120 is wrapped around the two sides of the steel cable fixed pulley connecting the retracting device 129, and the other end of the pull rope 120 is bound to the side wall of the aft deck space 12. When the drag reduction guide device 11 is folded up during transportation, the other end of the pull rope 120 is tightened into the aft deck space 12 and wrapped around and bound to the side wall of the aft deck space 12. The tension of the pull rope 120 allows the drag reduction guide device 11 to firmly fit and close the opening of the aft deck space 121, thereby facilitating the drag reduction guide device 11 to selectively close the opening of the aft deck space 121.

[0107] Further, the gun sled 3 of the present invention adopts the following structure, but is not limited thereto. The gun sled 3 may also adopt other structures. The gun sled 3 may include: a sled-shaped frame 32 and at least one air gun 31 array, each air gun 31 array is composed of a plurality of air guns 31 arranged at intervals, the sled-shaped frame 32 is a hollow frame, and the air guns 31 are suspended in the sled-shaped frame 32. By using the setting of the gun sled 3, the air guns 31 are all suspended in the sled-shaped frame 32, so that all the air guns 31 can be pulled together and transported to the place where the gun sled 3 is located. The air guns 31 are arranged in the aft deck space 12 at intervals, so that the air guns 31 will not be entangled or collided with each other. During navigation, the gun sled 3 may not be accurately docked to the aft deck space 12. The sled-shaped frame 32 has a narrow front and a wide rear structure, so that the gun sled 3 can cooperate with the resistance reduction guide device 11 to guide it into the aft deck space 12. The gun sled 3 can protect the internal air guns 31 from being hit by foreign objects in the water and prevent the air guns 31 from colliding with the riverbed when the gun sled 3 falls on the riverbed, and the navigation resistance is small.

[0108] Next, the sled-shaped frame 32 may include two spaced-apart top bending rods 321, two spaced-apart bottom bending rods 322 and six side rods 323, the side rods 323 being fixedly connected to the ends of adjacent top bending rods 321 and the ends of bottom bending rods 322, the middle of adjacent top bending rods 321 and the middle of bottom bending rods 322, a plurality of top cross rods 3211 being fixedly connected at intervals between the top bending rods 321, a plurality of top vertical rods 3212 being fixedly arranged at intervals between the top cross rods 3211, a plurality of bottom cross rods 3221 being fixedly arranged at intervals between the bottom bending rods 322, the top cross rod 3211, the bottom cross rod 3221 and the side rods 323 in the middle all separate two adjacent air gun 31 arrays, thereby making the overall weight of the sled-shaped frame 32 light and convenient for dragging.

[0109] Furthermore, the two ends of the air gun 31 can be suspended between two adjacent top cross bars 3211 through an inclined chain 33, so that the air gun 31 can be suspended in the sled-shaped frame 32 at intervals without interfering with each other, and the distance between the air gun 31 and the bottom bending rod 322 can be easily adjusted by adjusting the length of the chain 33, and the chain 33 is easy to disassemble and assemble.

[0110] In order to prevent the air gun 31 from colliding with the riverbed when the gun sled 3 falls on the riverbed, there may be a distance between the bottom of the air gun 31 and the bottom bending rod 322 in the vertical direction.

[0111] In order to improve the strength of the sled-shaped frame 32 of the present invention, an oblique support rod 324 can be fixedly connected between the middle side rod 323 and the adjacent top curved rod 321, between the middle side rod 323 and the adjacent bottom curved rod 322, between the middle side rod 323 and the adjacent bottom cross bar 3221, and between the middle side rod 323 and the adjacent top cross bar 3211; an oblique support rod 324 can be fixedly connected between the side rod 323 at the rear end and the adjacent top curved rod 321, between the side rod 323 at the rear end and the adjacent bottom curved rod 322, between the side rod 323 at the rear end and the adjacent bottom cross bar 3221, and between the side rod 323 at the rear end and the adjacent top cross bar 3211; an oblique support rod 324 can be fixedly connected between the side rod 323 at the front end and the adjacent bottom curved rod 322, and the oblique support rod 324 can play a reinforcing role.

[0112] Secondly, in order to facilitate the installation of the fixing cable 4, a wire rope ear 325 can be fixedly provided at the lower part of the rear end of the two top vertical rods 3212 adjacent to the top bending rod 321, and a connecting rod 326 with a wire rope ear 325 fixed at the lower part can be fixedly provided between the front ends of the two groups of adjacent top vertical rods 3212 adjacent to the top bending rod 321, and the wire rope ear 325 can be used to connect the fixing cable 4.

[0113] In addition, a front frame 34 may be fixedly provided at the front end of the sled-shaped frame 32 , and a protective mesh cover 35 may be provided between the bottom and the front of the front frame 34 , so as to prevent the sled-shaped frame 32 from being hit and damaging the air gun 31 .

[0114] Furthermore, in order to enable the buoy 2 to be quickly, conveniently and evenly stacked directly above the gun sled 3, a plurality of alignment return bodies 23 can be fixedly arranged at intervals on the bottom surface of the sealed cavity 21 below. In the embodiment, the number of the alignment return bodies 23 and the following buoy guide grooves 361 are both four, and the alignment return bodies 23 are respectively arranged adjacent to the corresponding cables 4, but this is not limited to the above. As the distance from the sealed cavity 21 increases, the width of the alignment return body 23 decreases, that is, the width of the alignment return body 23 away from the sealed cavity 21 is smaller than the width of the alignment return body 23 close to the sealed cavity 21. Two adjacent top vertical rods 3212 adjacent to the top bending rod 321 are respectively fixedly arranged with two buoys. The connecting plate 36 of the guide groove 361, the alignment and return body 23 is selectively aligned and inserted into the floating boat guide groove 361, and the connecting plates 36 are arranged at intervals, so as to utilize the matching alignment of the alignment and return body 23 and the floating boat guide groove 361. When the alignment and return body 23 touches the floating boat guide groove 361 away from the sealing chamber 21, since the alignment and return body 23 decreases with the increase of the distance from the sealing chamber 21, the alignment and return body 23 will go down accordingly until the alignment and return body 23 is close to the sealing chamber 21 and is stuck to the groove wall of the floating boat guide groove 361. At this time, the floating boat 2 is flatly stacked directly above the gun sled 3, and the floating boat 2 is not easy to be deflected, which is convenient for the floating boat 2 and the gun sled 3 to be dragged onto the rear deck space 12 together.

[0115] Furthermore, the alignment and return body 23 can have a plurality of truncated cones 231 connected in sequence as one body, and each truncated cone 231 has an annular belt 232 integrally formed on one side of the bottom surface of the sealing cavity 21. In this embodiment, the number of the truncated cones 231 is three, but it is not limited to this, and other numbers can also be used, so that the annular belt 232 can serve as a transition to prevent the motor 221 from tilting the alignment and return body 23 against the groove wall of the floating boat guide groove 361 when the motor 221 is a DC motor 221, and misjudging it as an overload, thereby starting the overload protection.
