The binding of the target ship 1 and the mother ship 2 is realized by the cooperation of the binding mechanism 32 and the binding ear seat 31, the binding between the target ship 1 and the mother ship 2 is tight and stable, and the possibility of collision between the two ships is avoided.

[0030] Before binding, please refer to Figure 4 , the binding ear seat 31 is located on the lower side of the bolt 323;

[0031] When binding, the telescopic end of the push rod device 322 extends downward, thereby driving the bolt 323 to extend downward, the bolt 323 is inserted into the hole of the binding ear seat 31, please refer to Figure 5 , so as to realize fast binding.

[0032] In this embodiment, the push rod device 322 can adopt a hydraulic cylinder, or a gas cylinder, or an electric push rod.

[0033] Please refer to Figure 1 , in this embodiment, the binding ear seat 31 and the binding mechanism 32 are correspondingly provided with three. Of course, two or four can also be set according to actual needs. In this way, the position of the target ship 1 and the mother ship 2 can be fixed to avoid collision.

[0034] Further, please refer to Figure 4 , 6The binding ear seat 31 is installed on the first bottom plate 311, and the first bottom plate 311 is fixedly connected with the target ship 1. By arranging the first bottom plate 311, the binding ear seat 31 is not directly connected with the target ship 1, and the positioning and installation of the plurality of binding ear seats 31 are facilitated.

[0035] Further, in order to improve the stability of the bolt 323 and prevent the target ship 1 from shaking to cause the telescopic rod of the push rod device 322 to bend, referring to Figure 4 、 5 The slide sleeve 324 is arranged on the rack 321 at the telescopic end of the push rod device 322, and the bolt 323 slides into the slide sleeve 324. In this way, when the target ship 1 shakes, the bolt 323 is limited by the slide sleeve 324, so that the bolt 323 does not swing, thereby avoiding the telescopic rod of the push rod device 322 from bending.

[0036] Embodiment two:

[0037] Based on the embodiment one, referring to Figure 3 、 4 , 5, the rack 321 is slidably connected with the second bottom plate 329 through the sliding structure 325, the second bottom plate 329 is fixedly connected with the mother ship 2, the second bottom plate 329 is provided with the rack 326, and the rack 321 is further provided with the driver 327, the output shaft of the driver 327 is provided with the gear 328, and the gear 328 is in meshing transmission with the rack 326. Through the sliding structure 325, the rack 321 can slide in the front and back direction along the second bottom plate 329, and the driver 327 drives the gear 328 to rotate when rotating, and the gear 328 is in meshing transmission with the rack 326, thereby driving the rack 321 to move. Through such a structure, the front and back positions between the target ship 1 and the mother ship 2 can be adjusted.

[0038] In the embodiment, the driver 327 is a reduction motor or a hydraulic motor with a brake. The hydraulic motor has a self-locking mechanism, that is, a brake oil cylinder, and the hydraulic motor cannot rotate when the brake oil cylinder is locked.

[0039] In the embodiment, referring to Figure 5 The sliding structure 325 includes the slide rails 3251 and the sliding blocks 3252, two slide rails 3251 are arranged in parallel and upward and downward, and the rack 321 is provided with the sliding blocks 3252 corresponding to the two slide rails 3251.

[0040] Specifically, the slide rail 3251 is selected as an inner groove rectangular guide rail, and the rectangular guide rail is a linear motion system component used for guiding and supporting a moving part in a mechanical device. A specially treated surface layer can provide good wear resistance and prolong service life. The rectangular guide rail can bear a larger load and is suitable for various heavy load applications. Due to the structural design, the rectangular guide rail system is easy to clean and lubricate, and the maintenance cost is relatively low. The cross-sectional shape of the rectangular guide rail provides good rigidity and anti-torsion capability. The slider 3252 is in a T-shaped structure, and one end of the T-shaped slider 3252 is mounted in the groove of the slide rail 3251.

[0041] Further, in order to facilitate the installation of the slider 3252 and improve the stability of the installation of the slider 3252, referring to Figure 5 , the mounting seat 3211 is arranged on the rack 321, and the slider 3252 is mounted on the mounting seat 3211. The gear 328 is located between the rack 321 and the second bottom plate 329.

[0042] The working principle or action process of the utility model is as follows:

[0043] First, the target ship 1 is attached to the mother ship 2, the driver 327 is started to drive the gear 328 to rotate, the gear 328 rotates to convert into linear motion through the gear rack, so as to adjust the relative position of the mooring mechanism 32 and the mooring lug seat 31 on the target ship 1, when it is aligned, the push rod device 322 is started, the extension end of the push rod device 322 extends downward, and the bolt 323 is inserted into the hole of the mooring lug seat 31, and the fast mooring is completed.

[0044] When the target ship 1 needs to be moved parallel to the mother ship 2 by a certain distance, the driver 327 is started again to drive the gear 328 to rotate, and the target ship 1 is moved forward and backward as a whole through the gear rack structure.

[0045] The advantages of the present application compared with the traditional cable mooring are:

[0046] 1. Increase the horizontal mooring force:

[0047] In the traditional mooring operation, due to the large height difference between the target ship and the bitt of the mother ship, the cable forms a certain angle when mooring. This angle causes the horizontal component force of the cable to be small, and further causes the mooring between the two ships to be not tight enough, which affects the stability and safety of the mooring. The present application adopts a bolt locking type, the pin shaft is inserted into the mooring lug seat of the target ship through the oil cylinder on the mother ship, forming a fast and stable locking type, and the horizontal component forces between the two are respectively applied to the sliding sleeve 324 and the mooring lug seat 31 of the target ship. Through the bolt locking type, the horizontal component force is directly applied to the bolt sheath and the mooring lug seat of the target ship. Due to the straight connection between the pin shaft and the lug seat, the angle problem in the traditional cable mooring is eliminated, thereby greatly improving the horizontal component force of the mooring.

[0048] 2. Improve the safety of horizontal moving ship:

[0049] When performing the task of clearing the dam, the target ship needs to move horizontally relative to the mother ship. In the traditional multi-point mooring method, the first step is to loosen the mooring cable, then move the target ship, and finally re-tighten the cable to complete the mooring. In this process, the step of loosening the cable is particularly dangerous. In front of the dam, due to the strong force of the water flow, after loosening the cable, the target ship may rotate around the corner of the mother ship's tail, and this uncontrollable movement may cause the two ships to collide, or even the target ship may hit the dam, causing serious damage. The present application uses a latch locking type to connect the target ship 1 and the mother ship 2. The latch 323 passes through the specially designed mooring ear seat 31 to form a quick and stable locking connection, ensuring that the two ships are always connected during movement. In order to realize the relative movement between the two ships, the present application also designs a gear and rack driving mechanism, which enables the target ship to move accurately and smoothly in the horizontal direction through the engagement of the gear and the rack.

[0050] 3. Improve the safety of two ships in mooring travel:

[0051] In the traditional mooring method, when the target ship and the mother ship travel side by side from the clearing dock to the dam clearing area, the mooring between the two ships usually relies on the cable and the cable pile. However, due to the elastic properties of the cable and the extensibility under stress, this mooring method has the following risks: the cable may stretch when subjected to the tension between the two ships, resulting in insufficient tightness of the mooring; and during travel, due to water flow, wind direction or other external factors, the two ships may collide randomly, which not only damages the hull, but also affects the stability of travel, thereby threatening the safety of the crew. The present application uses a rigid connection method of latch 323 and mooring ear seat 31 to replace the traditional cable and cable pile mooring. The latch 323 passes through the mooring ear seat 31 to form a solid mechanical connection. During mooring, the operator inserts the latch 323 into the mooring ear seat 31 of the target ship through a hydraulic or mechanical driving device to complete the rigid connection. This connection method is simple and quick, and does not require complex adjustments. During mooring travel, due to the length of the latch 323, the mooring ear seat 31 can slide down along the latch 323 without coming out of the latch 323 when the target ship 1 is under load. The rigid connection of the latch 323 and the mooring ear seat 31 ensures that the two ships are always fixed together, eliminating the risk of collision due to cable slackness or elastic deformation.
