[0030] The following will be further described in conjunction with the drawings and specific embodiments:

[0031] Embodiment 1

[0032] As Figure 1As shown, a long channel dual-vessel electric propulsion test device for enabling a boosted vessel to enter and exit a cabin comprises a maneuvering pool 1, a floating bridge 2 disposed within the maneuvering pool 1, a ship model 5, a booster boat model 6, and a power unit. The booster boat model 6 is connected to the ship model 5. The maneuvering pool 1 can simulate various water and sea conditions, enabling simulation tests in complex wind and wave environments and highly variable water levels. A mounting frame 20 is provided on the booster boat model 6, which is equipped with multiple cameras for recording the process of the booster boat model 6 propelling the ship model 5. Two floating bridges 2 are provided, both located within the maneuvering pool 1, with their lengths running the length of the pool. One end of each floating bridge 2 connects to one end of the maneuvering pool 1, forming a cabin structure. The other ends of the two floating bridges 2 are open, allowing the booster boat model 6 and the ship model 5 to enter the waters between the two floating bridges 2. Each pontoon 2 is equipped with a traction track 3, which runs the same length as the pontoon 2. Each traction track 3 is equipped with a track trolley 4, which is connected to the booster ship model 6 via a traction rope 13. The power device is a winch 9, whose drum is wrapped with a wire rope 10, and the winch 9 is connected to the track trolley 4 via the wire rope 10.

[0033] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown, the floating bridge 2 is composed of multiple rectangular pontoons 7, which are made of high-molecular polyethylene. A track mounting slot 701 is provided at the top of each pontoon 7. This slot 701 is rectangular or inverted T-shaped. In this embodiment, the slot 701 is an inverted T-shaped slot. A mounting steel plate 8 is provided on the bottom wall of the slot 701. Multiple threaded mounting holes 801 are provided along its length. The traction rail 3 is in the shape of an I-beam. Connecting holes are provided on the lower wing wall of the traction rail 3 at locations corresponding to the threaded mounting holes 801. These connecting holes are elongated and extend along the length of the traction rail 3. The traction rail 3 is secured to the mounting steel plate 8 via bolts. A complete traction rail 3 is constructed by sequentially connecting multiple shorter sections of traction rail 3. Each section of traction rail 3 is connected to or linked to the mounting steel plates 8 provided in the track mounting slots 701 of at least two pontoons 7. For example, the two sections of traction track 3 at each end are 1.5 times the length of the pontoon 7, while the remaining sections are each 2 times the length of the pontoon 7. This arrangement allows the traction track 3 to be installed and the pontoons 7 to be connected as a single unit, forming a complete floating bridge 2. Because the T-slot structure provides a retaining function, securing the sections of traction track 3 only requires bolting the two sections at each end. This effectively reduces the time required to install and dismantle the test device, significantly improving testing efficiency.

[0034] As shown in Figure 6 , Figure 7 and Figure 8 figures, a counterweight structure is provided on the floating box 7. The counterweight structure includes four counterweight grooves 703 provided at the four corners of the floating box 7 and counterweight blocks 11 provided in the counterweight grooves 703. Through the counterweight structure, the height of each floating box 7 exposed above the water surface can be conveniently controlled, and each floating box 7 can be adjusted to the same height. Vertical length scales 702 are provided on the side walls of the floating box 7. There are four length scales 702, which are respectively provided at the four corners of the floating box 7. The counterweight structure is used in conjunction with the length scales 702 to more accurately control the height of the floating box 7 exposed above the water surface. A cover plate is provided at the upper end of the counterweight groove 703. A connecting hole leading to the counterweight groove 703 is provided on the side wall of the floating box 7. A connecting pipe 12 is horizontally provided in this connecting hole. A valve is installed on the pipe body of the connecting pipe 12 outside the floating box 7. When the height of the floating box 7 exposed above the water surface cannot be accurately controlled only by using the counterweight blocks 11, a certain amount of water can be added to the counterweight groove 703, and then an appropriate amount of water can be discharged through the connecting pipe 12 to control the accuracy of the height of each part of the floating box 7 exposed above the water surface.

[0035] As shown in Figure 6 , Figure 7 and Figure 8 figures, an anti-collision structure is provided inside the floating box 7. The anti-collision structure includes a mounting guide rail 14, a T-shaped block 15, a U-shaped mounting plate 16 and a guide wheel 17. The mounting guide rail 14 is vertically provided on the side wall of the floating box 7 and is provided with a plurality of them along the length direction of the floating box 7. A T-shaped card slot 1401 adapted to the T-shaped block 15 is provided on the side of the mounting guide rail 14 away from the floating box 7. The T-shaped card slot 1401 is vertically provided. The T-shaped block 15 is provided in the T-shaped card slot 1401 and the height position in the T-shaped card slot 1401 can be adjusted. The U-shaped mounting plate 16 is connected to the T-shaped block 15, and the guide wheel 17 is horizontally installed in the U-shaped mounting plate 16. A rubber shock-absorbing sleeve is sleeved on the wheel body of the guide wheel 17. The anti-collision structure can effectively prevent the ship model 5 from directly hitting the floating box 7 and also has a rolling guiding function.

[0036] As shown in Figure 8 and Figure 9 figures, a hinge seat 18 is provided on the bottom wall of the floating box 7. A connecting rod 19 is hinged in the hinge seat 18. A connecting through hole is provided at one end of the connecting rod 19 away from the hinge seat 18. The floating boxes 7 corresponding to the two floating bridges 2 can be connected by the connecting rod 19 and bolts and nuts. In this way, the floating boxes 7 corresponding to the two floating bridges 2 can be connected, so that the distance between the two floating bridges 2 is always equal along the direction of the floating bridge 2, and a simulation test can be carried out more accurately.

[0037] As shown in Figure 2 and Figure 3As shown, the rail trolley 4 includes a frame 401, a connecting hook 402 disposed on the frame 401, and a walking wheel set. The walking wheel set includes a left wheel set and a right wheel set. Both the left wheel set and the right wheel set include an upper wheel 403, a middle wheel 404, and a lower wheel 405. The central axes of the upper wheel 403 and the lower wheel 405 are both along the horizontal direction, and the central axis of the middle wheel 404 is along the vertical direction. The frame 401 includes a left mounting plate 406 and a right mounting plate 407, and the structures of the left mounting plate 406 and the right mounting plate 407 are the same. The left wheel set and the right wheel set are respectively mounted on the left mounting plate 406 and the right mounting plate 407. A plurality of upper connecting shafts 21, a plurality of middle wheel mounting through holes, and a plurality of lower wheel mounting through holes are provided on the left mounting plate 406. One end of the upper connecting shaft 21 located on the right side of the left mounting plate 406 is connected to the upper wheel 403. The middle wheel mounting through holes are circular holes, and a first screw rod 22 is inserted through each middle wheel mounting through hole. Two locking nuts are mounted on the first screw rod 22, and these two locking nuts are respectively located on the left and right sides of the left mounting plate 406 for fixing the first screw rod 22. A U-shaped frame is provided at the right end of the first screw rod 22, and the middle wheel 404 is horizontally mounted in the U-shaped frame. The lower wheel mounting through holes are rectangular through holes, and their length directions are along the vertical direction. A second screw rod 23 is inserted through the lower wheel mounting through holes. Two locking nuts are also mounted on the second screw rod 23, and these two locking nuts are respectively located on the left and right sides of the left mounting plate 406. The right end of the second screw rod 23 is connected to the lower wheel 405. The structure of the right wheel set is the same as that of the left wheel set and they are symmetrically arranged. When the rail trolley 4 is placed on the towing track 3, first adjust the lower wheel 405 downward and the middle wheel 404 outward so that the distance between the upper wheel 403 and the lower wheel 405 is greater than the thickness of the upper wing plate of the towing track 3, and the distance between the middle wheels 404 of the left wheel set and the right wheel set is greater than the width of the upper wing plate of the towing track 3. After the rail trolley 4 is placed on the towing track 3, then adjust the lower wheel 405 upward and the middle wheel 404 inward so that the upper wheel 403 and the lower wheel 405 are respectively clamped on the upper and lower sides of the upper wing plate of the towing track 3, and the middle wheel 404 is in contact with the side wall of the upper wing plate of the towing track 3. The rail trolley 4 can move on the towing track 3, and the winch 9 can drive the rail trolley 4 through the steel wire rope 10 to provide additional braking force for the booster ship model 6.

[0038] Embodiment 2

[0039] As Figure 4As shown, a long channel dual-vessel electric propulsion system for testing the entry and exit of a boosted vessel in a cabin comprises a maneuvering pool 1, a floating bridge 2 disposed within the maneuvering pool 1, a ship model 5, and a booster boat model 6 connected to the ship model 5. The maneuvering pool 1 can simulate various water and sea conditions, enabling simulation tests in complex wind and wave environments and highly variable water levels. The booster boat model 6 is provided with a mounting frame 20, which is equipped with multiple cameras for recording the process of the booster boat model 6 propelling the ship model 5. Two floating bridges 2 are provided, both located within the maneuvering pool 1, with their lengths running the length of the pool. One end of each floating bridge 2 connects to one end of the maneuvering pool 1, forming a cabin structure. The other ends of the two floating bridges 2 are open, allowing the booster boat model 6 and the ship model 5 to enter the waters between the two floating bridges 2. Each pontoon 2 is provided with a traction track 3, and the length direction of the traction track 3 is the same as the length direction of the pontoon 2. Each traction track 3 is provided with a track trolley 4, and the track trolley 4 is connected to the booster ship model 6 by a traction rope 13.

[0040] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the floating bridge 2 is composed of a plurality of rectangular pontoons 7, which are made of high-molecular polyethylene material. A track mounting groove 701 is provided at the upper end of the pontoon 7. The track mounting groove 701 is a rectangular structure or an inverted T-slot structure. In this embodiment, the track mounting groove 701 is an inverted T-slot structure. A mounting steel plate 8 is provided on the bottom wall of the track mounting groove 701.

The W-shaped plate portion 302 is provided on the flat plate portion 301. A connecting through hole is provided on the flat plate portion 301 at a position corresponding to the mounting threaded hole 801. The connecting through hole is in the shape of an elongated strip, and its length direction is along the length direction of the traction rail 3. The flat plate portion 301 of the traction rail 3 is mounted on the mounting steel plate 8 by bolts. A complete traction track 3 is composed of multiple shorter sections of traction track 3 connected in sequence. Each section of traction track 3 is connected to or linked to the mounting steel plates 8 provided in the track mounting grooves 701 of at least two pontoons 7. For example, the two sections of traction track 3 at both ends of the traction track 3 are 1.5 times the length of the pontoons 7, and the other sections of traction track 3 are 2 times the length of the pontoons 7. Through the above arrangement, the traction track 3 can be installed and the pontoons 7 can be connected as a whole to form a complete floating bridge 2. Because the T-slot structure has a limiting function, when fixing the sections of the traction track 3, it is only necessary to use bolts to fix the two sections of traction track 3 at both ends. This can effectively reduce the time required to lay and dismantle the test device, effectively improving the test efficiency.

[0041] As Figure 6 , Figure 7 and Figure 8 shown, a counterweight structure is provided on the floating box 7. The counterweight structure includes four counterweight grooves 703 provided at the four corners of the floating box 7 and counterweight blocks 11 provided in the counterweight grooves 703. Through the counterweight structure, the height of each floating box 7 exposed above the water surface can be conveniently controlled, and each floating box 7 can be adjusted to the same height. Vertical length scales 702 are provided on the side walls of the floating box 7. There are four length scales 702, which are respectively provided at the four corners of the floating box 7. The counterweight structure is used in conjunction with the length scales 702 to more accurately control the height of the floating box 7 exposed above the water surface. A cover plate is provided at the upper end of the counterweight groove 703. A connecting hole leading to the counterweight groove 703 is provided on the side wall of the floating box 7. A connecting pipe 12 is horizontally provided in this connecting hole. A valve is installed on the pipe body of the connecting pipe 12 outside the floating box 7. When the height of the floating box 7 exposed above the water surface cannot be accurately controlled only by using the counterweight blocks 11, a certain amount of water can be added to the counterweight groove 703, and then an appropriate amount of water can be discharged through the connecting pipe 12 to control the accuracy of the height of each part of the floating box 7 exposed above the water surface.

[0042] As Figure 6 , Figure 7 and<° Figure 8 shown, an anti-collision structure is provided inside the floating box 7. The anti-collision structure includes mounting rails 14, T-shaped blocks 15, U-shaped mounting plates 16 and guide wheels 17. The mounting rails 14 are vertically provided on the side walls of the floating box 7 and are provided in multiple numbers along the length direction of the floating box 7. A T-shaped card slot 1401 adapted to the T-shaped block 15 is provided on the side of the mounting rail 14 away from the floating box 7. The T-shaped card slot 1401 is vertically provided. The T-shaped block 15 is provided in the T-shaped card slot 1401 and the height position in the T-shaped card slot 1401 can be adjusted. The U-shaped mounting plate 16 is connected to the T-shaped block 15. The guide wheel 17 is horizontally installed in the U-shaped mounting plate 16. A rubber shock-absorbing sleeve is sleeved on the wheel body of the guide wheel 17. The anti-collision structure can effectively prevent the ship model 5 from directly hitting the floating box 7, and at the same time has a rolling guiding function.

In this way, the floating boxes 7 corresponding to the two floating bridges 2 can be connected, so that the distance between the two floating bridges 2 is always equal along the direction of the floating bridge 2, and more accurate simulation tests can be carried out.

[0044] As Figure 5As shown, the track trolley 4 is a remote-controlled trolley mounted on the W-shaped plate 302. The power unit is a battery and power system installed inside the track trolley 4. Since this experiment does not require precise measurement, but only requires a visual demonstration, and the ship model 5 has a very low speed when entering and exiting the ship compartment, and the thrust and braking forces are also small, the track trolley 4 and traction track 3 can adopt the structure of this embodiment to save time and cost.

[0045] Working principle of the present invention: The present invention can simulate various water conditions and sea conditions by manipulating the water pool 1, and has the ability to carry out simulation tests of complex wind and wave environments and large-amplitude water level environments. The present invention uses a floating bridge 2 to simulate the side wall of the pilot channel, and uses a booster ship model 6 and a ship model 5 to simulate a booster ship and a ship passing through the lock, respectively. In this way, the present invention can be used to simulate and demonstrate the inter-ship effect, shallow water and bank wall effect, large-amplitude water level and cecal channel effect of ships propelling in and out of the ship compartment in narrow waters, laying the foundation for the creation of a theoretical system and method for nonlinear ship hydrodynamics for the Three Gorges Ship Lift. A mounting frame 20 is provided on the booster ship model 6, and a plurality of cameras are provided on the mounting frame 20. Each camera can shoot the entire process of the booster ship model 6 pushing the ship model 5.
