Description

Technical Field

[0001] The present invention relates to the field of mother-and-daughter ship connection structures, and in particular to a mother-and-daughter ship connection structure with a floating shock-absorbing function. Background Art

[0002] Electric ships use electricity as a power source and are a type of ship that uses green energy. When sailing, electric ships need to replenish battery power in time to facilitate the continuous sailing of the ship. As a cargo ship, the ship is responsible for cargo transportation. Its own weight and cargo load are large, and the battery volume and battery capacity required are also large. When charging, it is necessary to dock at the dock for a long time to recharge, which not only affects the docking of other ships, but also limits the sailing time of the ship. Electric batteries can be loaded behind the daughter ship to provide power for the mother ship loaded with cargo at any time, which can improve the problem of insufficient battery power when the mother ship is sailing on the water. The mother-daughter ship connection structure is a key component to achieve reliable connection, separation and collaborative work between the mother ship and the daughter ship.

[0003] Since the draft of the mother ship will be different due to its own weight and load when the ship is sailing on the water, the height of the connecting structure on the mother ship will change with the draft of the mother ship and must correspond to the position of the connecting structure on the daughter ship. Summary of the Invention

[0004] In view of this, the present invention provides a mother-and-daughter ship connection structure with a floating shock-absorbing function. The main technical problem to be solved is to provide a mother-and-daughter ship connection mechanism that can float according to the different draft depths of the mother ship.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a mother-and-daughter ship connection structure with a floating shock-absorbing function, comprising a mother ship and a daughter ship, the stern of the mother ship is equipped with a first connecting mechanism, the head of the daughter ship is equipped with a second connecting mechanism, the second connecting mechanism is installed on the first connecting mechanism, the first connecting mechanism comprises a connecting frame, the bottom of the connecting frame is fixedly connected to a track, the structure of the track is an arc structure, and a second connecting groove is provided on the back of the track, the second connecting mechanism comprises a fixed column, the left and right sides of the fixed column are fixedly connected to a protective cover, the interior of the fixed column is movably connected to a moving rod, the outer surface of the moving rod is fixedly connected to a rack, the interior of the protective cover is movably connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to a gear, the side of the gear is meshed with the side of the rack, the outer surface of the rotating shaft is fixedly connected to a clamping rod, the outer surface of the clamping rod is fixedly connected to a block, and the position of the block corresponds to the position of the second connecting groove.

[0006] By adopting the above technical solution, the mother ship and the daughter ship can be connected through the first connecting mechanism and the second connecting mechanism. When the mother ship's draft changes due to its own weight and load, the position of the track will also change. The arc-shaped track structure enables the connecting rod at the left end of the moving rod to be close to the first connecting groove on the track surface. When the draft of the mother ship changes, the track will float or sink. At this time, the second connecting mechanism will slide on the track, so that the daughter ship can change the connection position according to the floating changes of the mother ship, so that the daughter ship can always be connected to the mother ship. When in use, the daughter ship moves toward the mother ship, and the moving rod approaches the track. When the connecting rod at the left end of the moving rod contacts the first connecting groove on the track, the moving rod will move to the right. At this time, the rack on the connecting rod will also move, thereby driving the gear to rotate, driving the rotating shaft to rotate, and causing the clamping rod installed on the rotating shaft to rotate. When the clamping rod rotates, the block on the clamping rod will be stuck in the second connecting groove on the back of the track, so that the mother ship can be connected to the daughter ship through the first connecting mechanism and the second connecting mechanism.

[0007] As a further description of the above technical solution:

[0008] The connecting frame is installed at the tail of the mother ship, and the fixing column is installed at the head of the daughter ship.

[0009] By adopting the above technical solution, the daughter ship moves toward the tail of the mother ship, and the second connecting mechanism can be connected to the first connecting mechanism, so that the daughter ship can be connected to the mother ship.

[0010] As a further description of the above technical solution:

[0011] A first connecting groove is provided on the front side of the track, and the cross-sectional structure of the first connecting groove is a semicircular structure.

[0012] By adopting the above technical solution, the second connection is easily installed in the track.

[0013] As a further description of the above technical solution:

[0014] The left end of the moving rod is fixedly connected to a connecting rod, the left end of the connecting rod is provided with a hemispherical bump, and the position of the left end of the connecting rod corresponds to the position of the first connecting groove.

[0015] By adopting the above technical solution, the left end of the connecting rod can slide in the first connecting groove. When the mother ship floats up and down due to changes in the draft depth of the mother ship, the second connecting mechanism on the daughter ship can always be connected to the first connecting mechanism, thereby connecting the daughter ship and the mother ship together.

[0016] As a further description of the above technical solution:

[0017] The outer surface of the connecting rod is fixedly connected to a connecting plate, the outer surface of the connecting rod is sleeved with a spring, one end of the spring is fixedly connected to the outer surface of the connecting plate, and the other end of the spring is fixedly connected to the inner wall of the fixing column.

[0018] By adopting the above technical solution, when the daughter ship approaches the mother ship, the connecting rod will contact the first connecting groove on the track. Through the spring, part of the kinetic energy when the connecting rod contacts the track will be converted into elastic potential energy storage of the spring, thereby reducing the impact force when the connecting rod contacts the track, thereby extending the service life of the first connecting mechanism and the second connecting mechanism, and reducing the vibration generated when the connecting rod contacts the track.

[0019] As a further description of the above technical solution:

[0020] The right end of the moving rod is fixedly connected with a metal block, and the metal block is located inside the spring.

[0021] By adopting the above technical solution, the movable rod can be fixed inside the fixed column after the first connecting mechanism and the second connecting mechanism are connected together.

[0022] As a further description of the above technical solution:

[0023] An electromagnet is fixedly connected to the inner wall of the fixing column. The electromagnet is located inside the spring, and the position of the electromagnet corresponds to the position of the metal block.

[0024] By adopting the above technical solution, the metal block can be adsorbed by energizing the electromagnet. When the connecting block contacts the track, the daughter ship continues to move closer to the mother ship, and the metal block will move toward the electromagnet. When the metal block fits the electromagnet, it will be attracted and fixed by the electromagnet, thereby fixing the moving rod.

[0025] As a further description of the above technical solution:

[0026] A through hole is provided at the left end of the fixing column, the moving rod is located inside the through hole, and the interior of the fixing column is communicated with the interior of the protective cover.

[0027] By adopting the above technical solution, the movable rod can be easily moved inside the fixed column, and the rack can be driven to move when the movable rod moves, thereby driving the gear inside the protective cover to rotate.

[0028] By means of the above technical solution, the mother-and-daughter ship connection structure with floating shock-absorbing function of the present invention has at least the following beneficial effects:

[0029] 1. Compared with the existing technology, this mother-and-child ship connection structure with floating shock-absorbing function can connect the mother ship and the child ship through the first connecting mechanism and the second connecting mechanism. When the mother ship changes due to its own weight and loaded draft, the position of the track will also change. The arc-shaped track structure enables the connecting rod at the left end of the movable rod to be close to the first connecting groove on the track surface. When the draft of the mother ship changes, the track will float or sink. At this time, the second connecting mechanism will slide on the track, so that the child ship can change the connection position according to the floating changes of the mother ship, so that the child ship can always be connected to the mother ship.

[0030] 2. Compared with the existing technology, this mother-daughter ship connection structure with floating shock absorption function, when the daughter ship approaches the mother ship, the connecting rod will contact the first connecting groove on the track. Through the spring, part of the kinetic energy when the connecting rod contacts the track will be converted into elastic potential energy storage of the spring, thereby reducing the impact force when the connecting rod contacts the track, thereby extending the service life of the first connecting mechanism and the second connecting mechanism, and reducing the vibration generated when the connecting rod contacts the track.

The second connecting groove 204 is provided on the back of the track 202. The second connecting mechanism 3 includes a fixed column 301, which is installed on the head of the daughter ship 4. The left and right sides of the fixed column 301 are fixedly connected with a protective cover 302. The interior of the fixed column 301 is movably connected with a moving rod 303. The left end of the moving rod 303 is fixedly connected to the connecting rod 304. The left end of the connecting rod 304 is provided with a hemispherical bump. The position of the left end of the connecting rod 304 corresponds to the position of the first connecting groove 203, so that the left end of the connecting rod 304 can be in the first connecting groove 203. The second connecting mechanism 3 on the daughter ship 4 can be connected with the first connecting mechanism 2 all the time when the mother ship 1 floats up and down due to the change of the draft depth, so as to connect the daughter ship 4 with the mother ship 1. The outer surface of the moving rod 303 is fixedly connected with the rack 305, and the inner movability of the protective cover 302 is connected with the rotating shaft 310. The rotating shaft 310 can rotate in the protective cover 302. The outer surface of the rotating shaft 310 is fixedly connected with the gear 311. The side of the gear 311 is meshed with the side of the rack 305. When the rack 305 moves, the gear 311 will rotate, thereby driving the rotating shaft 310 to rotate. The outer surface of the rotating shaft 310 is fixedly connected with the clamping rod 312. When the rotating shaft 310 rotates, the clamping rod 312 will rotate around the rotating shaft 310. The outer surface of the clamping rod 312 is fixedly connected with a clamping block 313, and the position of the clamping block 313 corresponds to the position of the second connecting groove 204. The rotation of the clamping rod 312 will allow the clamping block 313 to enter the inside of the second connecting groove 204, so that the daughter ship 4 is connected to the mother ship 1. The mother ship 1 and the daughter ship 4 can be connected through the first connecting mechanism 2 and the second connecting mechanism 3. When the mother ship 1 changes its own weight and loaded draft, the position of the track 202 will also change. The arc-shaped track structure allows the connecting rod at the left end of the moving rod 303 to be close to the first connecting groove 203 on the surface of the track 202. When the draft of the mother ship 1 changes, the track 202 will float or sink, and at this time the second connecting mechanism 3 will slide on the track 202.This allows the daughter boat 4 to change its connection position following the floating changes of the mother ship 1, so that the daughter boat 4 can always be connected to the mother ship 1. When in use, the daughter boat 4 moves toward the mother ship 1, and the moving rod 303 approaches the track 202. When the connecting rod 304 at the left end of the moving rod 303 contacts the first connecting groove 203 on the track 202, the moving rod 303 will move to the right. At this time, the rack on the connecting rod 303 will also move, thereby driving the gear 311 to rotate, driving the rotating shaft 310 to rotate, so that the clamping rod 312 installed on the rotating shaft 310 rotates. When the clamping rod 312 rotates, the block 313 on the clamping rod 312 will be stuck in the second connecting groove 204 on the back of the track 202, so that the mother ship 1 can be connected to the daughter boat 4 through the first connecting mechanism 2 and the second connecting mechanism 3.

[0039] The outer surface of the connecting rod 304 is fixedly connected to the connecting plate 306, and the outer surface of the connecting rod 304 is sleeved with a spring, one end of the spring 307 is fixedly connected to the outer surface of the connecting plate 306, and the other end of the spring 307 is fixedly connected to the inner wall of the fixed column 301. When the daughter ship 4 approaches the mother ship 1, the connecting rod 304 will contact the first connecting groove 203 on the track 202. Through the spring 307, part of the kinetic energy of the connecting rod 304 when contacting the track 202 will be converted into elastic potential energy storage of the spring 307, thereby reducing the impact force when the connecting rod 304 contacts the track 202, thereby extending the service life of the first connecting mechanism 2 and the second connecting mechanism 3, and reducing the vibration generated when the connecting rod 304 contacts the track 202. The right end of the mobile rod 303 is fixedly connected to The metal block 308 is located inside the spring 307, so that the moving rod 303 can be fixed inside the fixed column 301 after the first connecting mechanism 2 and the second connecting mechanism 3 are connected together. The inner wall of the fixed column 301 is fixedly connected with an electromagnet 309. The daughter ship 1 supplies power to the electromagnet 309, which can be manually energized at the appropriate time. The electromagnet 309 is located inside the spring 307, and the position of the electromagnet 309 corresponds to the position of the metal block 308. By energizing the electromagnet 309, the metal block 308 can be adsorbed. When the connecting block 304 contacts the track 202, the daughter ship 4 continues to move closer to the mother ship 1, and the metal block 308 will move toward the electromagnet 309. When the metal block 308 fits with the electromagnet 309, it will be attracted and fixed by the electromagnet 309, thereby fixing the moving rod 303.

[0040] A through hole is provided at the left end of the fixed column 301, and the movable rod 303 is located inside the through hole. The interior of the fixed column 301 is connected with the interior of the protective cover 302, so that the movable rod 303 can move inside the fixed column 301, and the rack 305 can be driven to move when the movable rod 303 moves, thereby driving the gear 311 inside the protective cover 302 to rotate.

[0041] Working principle: When in use, the daughter boat 4 moves toward the mother boat 1, and the moving rod 303 approaches the track 202. When the connecting rod 304 at the left end of the moving rod 303 contacts the first connecting groove 203 on the track 202, the moving rod 303 will move to the right. At this time, the rack on the connecting rod 303 will also move, thereby driving the gear 311 to rotate, driving the rotating shaft 310 to rotate, and causing the clamping rod 312 installed on the rotating shaft 310 to rotate. When the clamping rod 312 rotates, the block 313 on the clamping rod 312 will be stuck in the second connecting groove 204 on the back of the track 202, so that the mother boat 1 can be connected to the daughter boat 4 through the first connecting mechanism 2 and the second connecting mechanism 3.
