[0040] Through the setting of the above structure, when detecting shallow seismic exploration, the exploration cable is placed on the upper side of the arc-shaped plate 2, the probe of the exploration cable is passed through the round mouth 204, and the upper side of the towline ring 4 is passed through the towline ring 4, when the cable probe gradually slides downward, the cable probe will directly contact with the inclined plate 406, so that the cable probe will extrude the inclined plate 406, so that the inclined plate 406 moves to the outside of the limit cylinder 401 in the inside of the strip-shaped mouth 407, and the inclined plate 406 is limited by the middle rod 404 and the middle hole 408, and the lower part of the inclined plate 406 moves outward, and the upper part of the rotating clamp plate 402 moves to the inside of the limit cylinder 401, and the notch 405 of the upper part of the rotating clamp plate 402 clamps the surface of the cable, so that the cable probe is directly limited after passing through the towline ring 4, so that the position of the cable probe is stabilized;

[0041] The two shell 1 between the upper side of towline ring 4 is fixed with arc-shaped plate 2, the left and right parts in the inside of arc-shaped plate 2 are provided with folding rod 201, and the middle part of the opposite side wall of the two folding rods 201 is provided with semicircular clamping hole 207;The opposite direction of the two shell 1 is provided with from gear 602, and the shaft end of from gear 602 is fixedly connected with the adjacent I-shaped winding roller 6;The rear position between the two shell 1 is provided with rotating support rod 5, the left and right ends of rotating support rod 5 are fixedly connected with connecting rod 502, and the other end of connecting rod 502 is fixedly connected with main gear 503, and the main gear 503 is engagedly connected with the adjacent from gear 602;

[0042] Through the arrangement of the above structure, when the cable probe is at the position of the towline ring 4 and continues to move downward, the cable probe will move the towline ring 4 downward, and the rotating support rod 5 is rotated by the worker, so that the rotating support rod 5 drives the slave gear 602 to rotate through the connecting rod 502 and the main gear 503, and then the slave gear 602 drives the I-shaped winding roller 6 to rotate, so that the I-shaped winding roller 6 loosens the pull rope 601, and at the same time the cable probe will directly pull the pull rope 601 after moving downward, so that the towline ring 4 can gradually move downward. When the cable needs to be rolled up, the cable is placed in the semicircular clamping hole 207 between the two rolling rods 201, and the probes on both sides of the cable and the plugs are respectively arranged at the left and right parts of the semicircular clamping hole 207. Therefore, by rotating the two rolling rods 201, the rolling rods 201 roll up the cable, so that the cable probe moves upward, achieving the purpose of quickly rolling up the cable.

[0043] wherein as Figure 1 、 3 , each of the left and right parts of the lower side of each shell 1 is fixed with a wheel set 7, the pull rope 601 in each shell 1 is wound around the adjacent wheel set 7 from bottom to top, the opposite side walls of the two shells 1 are fixed with protective shells 101, the main gear 503 and the slave gear 602 are respectively arranged in the corresponding protective shell 101, the surface side of the rotating support rod 5 is fixed with a rotating frame 501, and the rotating frame 501 is annularly and uniformly distributed along the circumferential side of the rotating support rod 5, the connecting rod 502 is rotatably connected with the corresponding protective shell 101 through a bearing, when the pull rope 601 is loosened, the pull rope 601 is pulled by the towline ring 4, and the friction between the pull rope 601 and the wheel set 7, so that the pull rope 601 drives the wheel set 7 to rotate, thereby avoiding the friction between the pull rope 601 and the wheel set 7.

[0044] wherein as Figure 1 、 5As shown in Figure 6, support plates 302 are fixed between the lower side of the housing 1 at the front and rear of the wheel set 7 and the base plate 3. A through hole 301 is opened at the upper end of the base plate 3 corresponding to the position of the tow cable ring 4. A round opening 204 is opened at the lower side of the arc plate 2 corresponding to the position of the tow cable ring 4. Springs 206 are fixed between the opposite ends of the two retracting rods 201 and the arc plate 2. Fan-shaped support plates 202 are fixed on the inner side between the round opening 204 and the left and right sides of the arc plate 2. Support holes 2021 are opened on the side walls of the fan-shaped support plates 202 corresponding to the side walls of the retracting rods 201. The fan-shaped support plates 202 are sleeved on the outer side walls of the adjacent retracting rods 201 through the support holes 2021. Axles are opened on the left and right sides of the arc plate 2 corresponding to the positions of the retracting rods 201. Both the hole 203 and the other end of the spring 206 are fixed with baffles 205. Each baffle 205 is fixed with a shaft 2051 near the shaft hole 203, and the shaft 2051 is placed in the corresponding shaft hole 203. When it is necessary to loosen the cable by the two retracting rods 201, the distance between the two retracting rods 201 is increased by moving the two retracting rods 201 in opposite directions. At the same time, the retracting rods 201 will slide at the support hole 2021 of the fan-shaped support plate 202, and the retracting rods 201 will directly squeeze the spring 206. When the retracting rods 201 retract the cable, the retracting rods 201 will drive the spring 206 and the baffle 205 to rotate inside the shaft hole 203 through the shaft 2051.

[0045] Among them, such as Figures 7-9 As shown, a magnetic plate 409 is fixed to the center of the upper side of the tow cable ring 4 at the position of the strip opening 407, and a metal plate 403 is fixed to the center of the lower side of the rotating clamping plate 402. A central rod 404 is fixed to the center of the side wall of the rotating clamping plate 402 that connects with the limiting cylinder 401. A central hole 408 is opened on the side wall of the limiting cylinder 401 at the position corresponding to the central rod 404, and the central rod 404 is rotated and placed inside the corresponding central hole 408. After the inclined plate 406 is pushed, the rotating clamping plate 402 will rotate, and the rotating clamping plate 402 will drive the central rod 404. The position of the central hole 408 is rotated, and the central hole 408 limits the central rod 404, thereby limiting the rotating plate 402 inside the slot 407. When the cable probe moves out of the limiting cylinder 401, the lower part of the rotating plate 402 is heavier because the inclined plate 406 is located at the lower part of the rotating plate 402. As a result, the rotating plate 402 will rotate downward through the inclined plate 406, and at the same time, the metal plate 403 will be attracted by the magnetic plate 409 at the lower part of the slot 407, thereby enabling the rotating plate 402 to quickly reset.

[0046] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
