Description

Technical Field

[0001] The present invention relates to the technical field of split ships, and particularly to a split ship and a docking method thereof. Background Art

[0002] A split ship is usually composed of a power ship providing motive power and a barge installing functional equipment. In order to meet specific requirements such as fire extinguishing and environmental protection, different functional equipment can be installed on the barge, so that the combined ship becomes various functional ships such as a fire-fighting ship, an oil spill recovery ship, a garbage recovery ship, and a rescue ship.

[0003] A split ship usually moves by using a push boat as a power ship to push a barge. The most common push boat connection forms at home and abroad are push frame - steel cable type, articulated two - pin type, and three - pin fixed type. These connection forms each have some design defects: (1) The push frame - steel cable type push boat is connected to the barge through a steel cable, and the steel cable is tightened by a winch. This connection method has a simple structure but takes a long time to connect, and the barge has strong mobility relative to the power ship; (2) The articulated two - pin type push boat and the pushed ship are connected through a fitting pin rod. This connection method cannot limit the relative pitching of the two hulls, resulting in poor stability of the combined hull, and local stress concentration occurs at the pin rod position, which will cause structural fatigue, wear, or damage; (3) The three - pin fixed type is an improved type of the articulated two - pin type, that is, a longitudinal connection pin is added at the front end of the push boat to form a rigid connection. Although this connection method limits the relative pitching of the two hulls, there is still a problem of stress concentration on the pin rod.

[0004] Therefore, how to solve the problems of long connection time and stress concentration existing in current distributed ships, greatly improve the docking speed between the power ship and the functional barge, and at the same time, as much as possible, disperse the local stress originally concentrated on the connection part between the power ship and the functional barge has become an urgent problem to be solved by researchers in this field. Summary of the Invention

[0005] In view of this, the present invention provides a split ship and a docking method thereof, which are used to solve the problems of long connection time and stress concentration existing in current distributed ships.

[0006] The technical solution of the present invention is realized as follows: The present invention provides a split-type ship, including a functional hull, with two fixing parts symmetrically arranged at one end; a power hull, provided with a docking end for docking with the functional hull; an adsorption assembly, arranged on the docking end; a locking assembly, arranged on both sides of the power hull; wherein, the power hull moves towards the functional hull, the adsorption assembly has a free end and the free end extends towards the functional hull along the moving direction of the power hull relative to the power hull, and the free end of the adsorption assembly adsorbs on the surface of the functional hull; the power hull approaches the functional hull as the free end of the adsorption assembly retracts, and the docking end enters between the two fixing parts; the locking assembly locks the power hull between the two fixing parts.

[0007] Based on the above technical solution, preferably, the adsorption assembly includes a telescopic mechanism, one end of which is arranged inside the power hull and the other end extends horizontally outward through the docking end; a suction cup, arranged on the free end of the telescopic mechanism and capable of adsorbing or detaching from the surface of the functional hull; wherein, the suction cup is hinged to the free end of the telescopic mechanism, and the suction cup can rotate axially around the horizontal direction relative to the free end of the telescopic mechanism.

[0008] More preferably, four adsorption assemblies are arranged on the docking end, and the four adsorption assemblies are symmetrically arranged in two groups, and the two groups of adsorption assemblies are arranged at intervals up and down.

[0009] More preferably, when the functional hull is docked with the power hull, one end of the functional hull facing the docking end is tilted upward relative to the horizontal plane and the tilting angle relative to the horizontal plane is θ 1 , the docking end is tilted upward relative to the horizontal plane and the tilting angle relative to the horizontal plane is θ 2 ; when each adsorption assembly adsorbs the functional hull at the same time, the extended lengths of the free ends of the two telescopic mechanisms located above are L 1 and L 2 , the extended lengths of the free ends of the two telescopic mechanisms located below are L 3 and L 4 , the control equation for the extension amount of each adsorption assembly is

[0010]

[0011] wherein, L max represents the maximum extended length of the telescopic mechanism, and d represents the vertical distance between the upper and lower two groups of adsorption assemblies as d.

[0012] More preferably, the locking assembly includes a movable part disposed on the side of the power hull; wherein, on the mutually facing sides of the two fixed parts, tooth tracks are symmetrically arranged, and both ends of the tooth tracks extend in the vertical direction of the horizontal plane; the movable part horizontally moves relative to the power hull in the vertical direction perpendicular to the moving direction of the power hull. When the power hull approaches the functional hull and aligns the movable part with the tooth track, a biting tooth is arranged on the end of the movable part facing the fixed part. The movable part abuts against the side of the fixed part and makes the biting tooth bite the tooth track.

[0013] More preferably, the locking assembly further includes a gear disposed on the end of the movable part away from the side of the power hull; wherein, biting teeth are arranged on the surface of the gear, the gear rotates axially in the horizontal direction, and the gear cooperates with the tooth track and moves along the tooth track to adjust both sides of the power hull to be horizontal.

[0014] More preferably, the locking assembly further includes a holding part disposed on the movable part; wherein, the holding part moves relative to the movable part in the moving direction of the movable part, and the holding part abuts against the surface of the gear and locks the gear.

[0015] On the other hand, the present invention also provides a docking method for a split-type ship, using the above-mentioned split-type ship, including the following steps: S1, the power hull moves towards the functional hull and aligns the docking end with the functional hull; S2, the telescopic mechanism extends and makes the suction cup adsorb on the functional hull. The power hull moves along with the retraction of the telescopic mechanism and approaches the functional hull until the docking end is located between the two fixed parts; S3, the locking assembly locks the power hull between the two fixed parts.

[0016] Based on the above technical solutions, preferably, in step S1, when the distance between the docking end and the functional hull is less than half of the maximum extension length of the telescopic mechanism, the power hull and the functional hull start to dock.

[0017] Based on the above technical solutions, preferably, step S3 includes the following steps: S31, the power hull enters between the two fixed parts and aligns the movable part with the tooth track; S32, the movable part moves towards the fixed part relative to the power hull and makes the gear abut against the tooth track; S33, the gear rotates and rolls on the tooth track until both sides of the power hull reach horizontal, and the holding part moves towards the gear relative to the movable part, and the holding part abuts against and locks the gear.

[0018] A split-type ship and its docking method of the present invention have the following beneficial effects compared with the prior art:

[0019] (1) The present invention adsorbs the functional hull through the adsorption component to guide the power hull to approach the functional hull. When the docking end enters between the two fixing parts, the relative positions of the power hull and the functional hull can be quickly positioned. Then, the two hulls are locked by the locking component. The docking efficiency is high and the speed is fast. At the same time, the docking end is tightly adsorbed on the functional hull through the adsorption component, avoiding relative pitching of the two hulls, and the stress of the docking structure of the two hulls is dispersed by the locking component and the adsorption component.

[0020] (2) The present invention locks the relative positions of the two hulls by driving a gear to bite the tooth track on the fixing part through a horizontally moving movable part. The gear can roll on the tooth track, thereby adjusting the lateral tilt angle of the power hull and restoring the horizontal balance on both sides of the power hull, avoiding the problem that the center of gravity of the power hull and the center of gravity of the functional hull are not on the same straight line, resulting in the overall ship rolling over.

[0030] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0031] As Figure 1 shown, in combination with Figure 2 and Figure 3 , a split ship of the present invention includes a functional hull 1, a power hull 2, an adsorption component 3 and a locking component 4.

[0032] Among them, the functional hull 1 is a barge, and functional equipment is installed on the barge. For example, in this application Figure 1 , the functional hull 1 is a river garbage collection ship. Therefore, a flow baffle and a collection net for collecting garbage are provided at the front end, and two fixed parts 11 are symmetrically arranged at the tail end of the functional hull 1.

[0033] The power hull 2 is provided with a docking end 21 for docking with the functional hull 1. The outer contour of the docking end 21 and the inner contour surrounded by the two fixed parts 11 are matched.

[0034] The adsorption component 3 is arranged on the docking end 21; when the power hull 2 moves towards the functional hull 1, the adsorption component 3 has a free end and the free end extends towards the functional hull 1 along the moving direction of the power hull 2 relative to the power hull 2, and the free end of the adsorption component 3 is adsorbed on the surface of the functional hull 1; the power hull 2 approaches the functional hull 1 as the free end of the adsorption component 3 retracts, and the docking end 21 enters between the two fixed parts 11. By adsorbing the functional hull 1 with the adsorption component 3, the power hull 2 is guided to approach the functional hull 1. When the docking end 21 enters between the two fixed parts 11, the relative positions of the power hull 2 and the functional hull 1 can be quickly positioned, and then the two hulls are locked by the locking component 4. The docking efficiency is high and the speed is fast. At the same time, the docking end 21 is tightly adsorbed on the functional hull 1 through the adsorption component 3, avoiding relative pitching of the two hulls, and the stress of the docking structure of the two hulls is dispersed by the locking component 4 and the adsorption component 3.

[0035] The locking component 4 is arranged on both sides of the power hull 2; the function of the locking component 4 is to lock the power hull 2 between the two fixed parts 11.

[0036] In Figure 4 the preferred embodiment shown, specifically, the adsorption assembly 3 includes a telescopic mechanism 31 and a suction cup 32.

[0037] Among them, the telescopic mechanism 31 can adopt a hydraulic telescopic cylinder, or an electric telescopic rod or a pneumatic telescopic rod. One end of the telescopic mechanism 31 is a fixed end and is arranged inside the power hull 2, while the other end of the telescopic mechanism 31 is a free end that extends horizontally outward through the docking end 21.

[0038] The suction cup 32 uses a vacuum adsorption method to achieve adsorption of the functional hull 1. The suction cup 32 is arranged on the free end of the telescopic mechanism 31 and can adsorb or disengage from the surface of the functional hull 1. A vacuum pumping device is arranged on the power hull 2 and is connected to the suction cup 32; the suction cup 32 is hingedly connected to the free end of the telescopic mechanism 31, and the suction cup 32 can rotate axially around the horizontal direction relative to the free end of the telescopic mechanism 31. Thus, when the two ends of the power hull 2 and the functional hull 1 that are docked are relatively lifted due to the pitching of the hull, the suction cup 32 can still effectively adsorb on the surface of the functional hull 1.

[0039] In Figure 4 the preferred embodiment shown, four adsorption assemblies 3 are arranged on the docking end 21. The four adsorption assemblies 3 are symmetrically arranged in two groups, and the two groups of adsorption assemblies 3 are arranged at intervals up and down. The four adsorption assemblies 3 can greatly improve the connection strength between the power hull 2 and the functional hull 1, and at the same time help to disperse the connection stress.

[0040] In Figure 5 the preferred embodiment shown, when the functional hull 1 and the power hull 2 pitch during the docking process, the extension amount of each adsorption assembly 3 is controlled by a working condition machine. When the functional hull 1 and the power hull 2 are docked, one end of the functional hull 1 facing the docking end 21 is lifted upward relative to the horizontal plane and the lifting angle relative to the horizontal plane is θ 1 , and the docking end 21 is lifted upward relative to the horizontal plane and the lifting angle relative to the horizontal plane is θ 2 ; when each adsorption assembly 3 adsorbs the functional hull 1 at the same time, the extension lengths of the free ends of the two telescopic mechanisms 31 located above are L 1 and L 2 , and the extension lengths of the free ends of the two telescopic mechanisms 31 located below are L 3 and L 4 , and the control equation for the extension amount of each adsorption assembly 3 is,

[0041]

[0042] Among them, L maxL represents the maximum extended length of the telescopic mechanism 31, and d represents the vertical distance d between the upper and lower adsorption components 3. Therefore, during the docking process of the functional hull 1 and the power hull 2, specifically, the functional hull 1 is anchored and randomly swayed with the water flow. The power hull 2 is operated to approach the tail end of the functional hull 1, and the power hull 2 is kept as much as possible in the same straight line with the functional hull 1 to ensure that the deviation degree of the power hull 2 and the functional hull 1 in the horizontal direction is not too large. At this time, the telescopic mechanisms 31 of the two upper adsorption components 3 extend and control the telescopic amount L 1 and L 2 is half of L max The extended amount of the telescopic mechanism 31 of the lower adsorption component 3 satisfies the above formula, and the extended amount of the telescopic mechanism 31 of the lower adsorption component 3 changes at any time with the pitching angle change of the power hull 2 and the functional hull 1; at this time, the power hull 2 gradually approaches the functional hull 1 in the state where each adsorption component 3 extends, and the vacuum adsorption function of the suction cup 32 is turned on, so that each adsorption component 3 is successfully adsorbed on the surface of the functional hull 1.

[0043] In Figure 6 the preferred embodiment shown, specifically, the locking component 4 includes a movable part 41.

[0044] Among them, tooth tracks 12 are symmetrically arranged on the mutually facing side surfaces of the two fixing parts 11, and both ends of the tooth tracks 12 extend in the vertical direction of the horizontal plane.

[0045] The movable part 41 is arranged on the side of the power hull 2; the movable part 41 moves horizontally relative to the power hull 2 in the vertical direction perpendicular to the moving direction of the power hull 2. The power hull 2 approaches the functional hull 1 and aligns the movable part 41 with the tooth track 12. A bite tooth is arranged on the end of the movable part 41 facing the fixing part 11. The movable part 41 abuts against the side surface of the fixing part 11 and makes the bite tooth bite the tooth track 12, thereby locking the power hull 2.

[0046] In Figure 7 the preferred embodiment shown, compared with the previous embodiment, the locking component 4 further includes a gear 42.

[0047] Among them, the gear 42 is arranged at the end of the movable part 41 away from the side of the power hull 2; the teeth are arranged on the surface of the gear 42, the gear 42 rotates axially in the horizontal direction, the gear 42 is matched with the tooth track 12 and moves along the tooth track 12, so that both sides of the power hull 2 are adjusted to be horizontal. In the previous embodiment, locking the relative position of the two hulls by locking the movable part 41 with the teeth at the front end of the movable part 41 will cause serious stress concentration problems at the front end of the movable part 41. In this embodiment, through the cooperation of the gear 42 and the tooth track 12, the contact area is larger and the stress is dispersed. At the same time, since the power hull 2 will actually sway left and right relative to the functional hull 1 under the influence of waves during the docking process (the functional hull 1 will also sway left and right), when the gear 42 bites the tooth track 12, both sides of the power hull 2 may be inclined to one side relative to the horizontal plane, which will cause the centers of gravity of the power hull 2 and the functional hull 1 not to be on the same straight line, and then lead to the risk of the center of gravity of the entire ship shifting and possible capsizing. Therefore, the driving motor installed in the movable part 41 drives the gear 42 to rotate, so that the gear 42 rolls on the tooth track 12, thereby being able to adjust the roll angle of the power hull 2 and making both sides of the power hull 2 reach horizontal balance.

[0048] In Figure 7 In the preferred embodiment shown, the locking assembly 4 further includes an abutting portion 43.

[0049] Among them, the abutting portion 43 is arranged on the movable part 41; a telescopic cylinder can be installed in the movable part 41, the free end of the telescopic cylinder is connected with the abutting portion 43, the abutting portion 43 moves relative to the movable part 41 along the moving direction of the movable part 41, and the abutting portion 43 abuts against the surface of the gear 42 and locks the gear 42, thereby locking the relative position of the power hull 2 and the functional hull 1.

[0050] As Figure 1 shown, in combination with Figure 2 and Figure 3 , a docking method for a split ship according to the present invention, using the split ship of any of the above embodiments, includes the following steps:

[0051] S1, the power hull 2 moves towards the functional hull 1 and aligns the docking end 21 with the functional hull 1.

[0052] S2, the telescopic mechanism 31 extends and the suction cup 32 adsorbs on the functional hull 1, and the power hull 2 moves with the retraction of the telescopic mechanism 31 and approaches the functional hull 1 until the docking end 21 is located between the two fixing parts 11.

[0053] S3, the locking assembly 4 locks the power hull 2 between the two fixing parts 11.

[0054] In Figure 5In the preferred embodiment shown, in step S1, at the beginning of docking, when the distance between the docking end 21 and the functional hull 1 is less than half of the maximum extended length of the telescopic mechanism 31, the power hull 2 starts to dock with the functional hull 1 to avoid excessive extension of the adsorption assembly 3, making it difficult to accurately control the suction cup 32 to adsorb onto the surface of the functional hull 1.

[0055] In Figure 7 In the preferred embodiment shown, step S3 includes the following steps:

[0056] S31, the power hull 2 enters between the two fixed parts 11 and aligns the movable part 41 with the tooth track 12.

[0057] S32, the movable part 41 moves relative to the power hull 2 towards the fixed part 11 and makes the gear 42 abut against the tooth track 12.

[0058] S33, the gear 42 rotates and rolls on the tooth track 12 until both sides of the power hull 2 reach a horizontal position. The abutting part 43 moves relative to the movable part 41 towards the gear 42, and the abutting part 43 abuts against and locks the gear 42.

[0059] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
