Description

Technical Field

[0001] The present invention relates to the technical field of ships, in particular to a modular ship. Background Art

[0002] In the field of fixed-line bulk cargo shipping, the balance between power economy and load effectiveness has always been a difficult part of ship design. Ordinary cargo ships are equipped with fixed power systems regardless of whether they are sailing with cargo, berthing for loading and unloading, or waiting for cargo without cargo. However, except for the sailing state, the power system is a useless load of the ship in other states and cannot serve other transportation tasks. Due to the large weight of the power system, which usually accounts for 30% of the total empty ship weight, and occupies precious cargo space, it also requires the configuration of supporting resources such as fuel and power batteries, which is not conducive to economy in bulk cargo transportation, especially in the field of fixed-line navigation.

[0003] In the field of ship mooring devices, conventional mooring equipment and devices such as cables and bollards are usually used to connect or release two ships side by side. When using conventional mooring devices, personnel are required to throw or reel in cables to the target ship, wrap around the bollards to fix them, or untie the knots to release them. Both ships require 4 to 6 people to work at fixed points on the deck. When operating between large-scale ships, conventional mooring devices take a long time to operate, usually taking 10-15 minutes; they occupy human resources for outdoor operations, which poses certain safety hazards; if the two ships are in a navigation and driving state, the ship's posture control requirements are high; if the height difference between the two ship sides is large, the cable tension needs to be continuously adjusted, and the operation intensity is high.

[0004] Therefore, a new type of ship is urgently needed to solve the above-mentioned technical defects. Summary of the invention

[0005] The present invention provides a modular ship, the purpose of which is to overcome at least one of the above-mentioned technical defects.

[0036] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] In order to balance the power economy and load effectiveness of cargo ships, the present invention adopts a power-load combinable ship type, which uses a combined form to design the power and load parts of the ship. When sailing with cargo, the power ship and the load ship are combined into one, and the power ship provides power for the load ship; after completing the navigation mission, the power ship is separated from the load ship through a release device, and the load ship is moored for loading and unloading or empty waiting for cargo, and the power ship is combined with other loaded load ships through the release device to perform the next voyage; after the moored load ship completes loading and unloading, it can wait for the next power ship to be combined to perform the navigation mission. According to Figure 1-Figure 4 As shown, a modular ship provided by the present invention comprises: a power ship 100, a load ship 200, and two release devices 300. The power ship 100 and the load ship 200 are connected through the release device 300 to achieve the connection or release between the power ship 100 and the load ship 200 to meet the needs of different occasions. The release or connection process is automatically controlled, and the time is shortened to 5 minutes, which has high work efficiency and saves time and labor.

[0038] Specifically, the draft and size of the power ship 100 and the load ship 200 meet the requirements of the waterway and the dock, and the power ship 100 is mainly powered and does not bear the cargo function. The power of the main power system should meet the requirements of economic navigation (such as more than 10 knots) under the full load condition of the load ship 200 after combination. The power ship 100 in the present invention provides power, only has a power cabin and a cockpit, and has no special carrying facilities and space; in order not to affect the linear shape and loading space of the carrying ship and ensure the propulsion efficiency, the ship sets the propeller below the bottom of the ship to form a unique bottom propulsion form, and the propeller can adopt various forms such as straight blade propellers or pods according to needs;

[0039] according to Figure 1 As shown, the side of the load ship 200 close to the power ship 100 is U-shaped 201, and the opening direction of the U-shaped 201 faces the power ship 100. The release devices 300 are respectively arranged on the power ship 100 at positions corresponding to the two sides of the U-shaped 201 structure, so that after one end of the power ship 100 is inserted into the opening of the U-shaped 201 structure, the power ship 100 and the load ship 200 are connected through the release device 300; the middle part of the load ship 200 in the present invention is used for transportation, such as a liquid cargo storage tank group, and can also be replaced by a dry bulk cargo compartment; this part has no power device, and there is no need to vacate the layout space of the power device, so there is no power cabin, chimney and cab and other general transport ship settings;

[0040] according to Figure 1 , Figure 5As shown, in order to ensure the stability and convenience of the connection between the power ship 100 and the load ship 200, the release devices 300 are preferably provided with two, wherein the two release devices 300 are symmetrically located on both sides of the end of the power ship 100 connected to the load ship 200, and both sides of the load ship 200 adapted to the release devices 300 are hingedly connected to two vertical card slot plates 202 arranged opposite to each other, and the direction away from the release device 300 is the opening direction (i.e., the hinge opening and closing direction); each of the vertical card slot plates 202 is provided with an arc groove 202a, so that the arc grooves 202a at corresponding positions on the two vertical card slot plates 202 are relatively opened to form a card slot hole 203 in space, the The release device 300 pushes open the vertical slot plates 202 arranged opposite to each other, and is used to connect the load ship 200 and the power ship 100 through the slot hole 203. At this time, the two vertical slot plates 202 on the load ship 200 are arranged in parallel to each other and are located on the same straight line, so as to clamp the release device 300 and prevent it from being separated therefrom; in order to adapt to the connection or separation between ships with different side height differences (for example, 3 meters), a plurality of arc grooves 202a are provided on the vertical slot plates 202, and are all arranged along the height direction of the vertical slot plates 202; in the specific implementation process, the release device 300 is inserted into or separated from the slot hole 203, and is used to connect or separate the power ship 100 from the load ship 200;

[0041] In order to enhance convenience, the end surface material of the slot hole 203 on the side away from the release device 300 is rigid, so that after the release device 300 is inserted, it cannot be detached because the diameter of the slot hole 203 is smaller than the diameter of the release device 300; except for the rigid side, the other structures on the slot hole 203 are made of flexible material, so that when the release device 300 abuts against the slot hole 203, the slot hole 203 gradually becomes larger due to the flexibility, and combined with the hinge connection between the above-mentioned vertical slot plate 202 and the load ship 200, that is, the setting of the opening and closing direction, the release device 300 can be automatically inserted, which is convenient, fast, time-saving and labor-saving.

[0042] In a specific technical solution: in order to realize the rapid and accurate connection and disconnection between the power ship 100 and the load ship 200, the release device 300 includes a tenon head 301 adapted to the slot hole 203, a bracket assembly 302, and a hydraulic control system 303. The bottom end of the bracket assembly 302 is fixed to the power ship 100, and the hydraulic control system 303 is located on the bracket assembly 302. The tenon head 301 is fixed to the front end of the inner cylinder body 303a on the hydraulic control system 303, and the front end of the inner cylinder body 303a is oil-sealed and air-tight, so that the hydraulic control system 303 pushes or pulls the tenon head 301 to insert into or disconnect from the slot hole 203 during the movement, so as to realize the rapid connection or disconnection between the power ship 100 and the load ship 200;

[0043] Further, according to Figure 8 As shown, the cross section of the tenon head 301 is a trapezoid, and the upper base of the trapezoid is located at a side close to the vertical slot plate 202 , and the lower base is located at a side away from the vertical slot plate 202 .

[0044] In the specific technical solution: according to Fig.10 , Fig.11 As shown, the hydraulic control system 303 also includes an outer cylinder 303b, a telescopic cylinder 303c for containing hydraulic oil, a tail end inspection cover 303d, a telescopic cylinder sleeve 303e, and a hydraulic pipe 303f. One end of the inner cylinder 303a away from the tenon head 301 is sleeved with one end of the telescopic cylinder 303c, and the other end is detachably connected with the tail end inspection cover 303d. The longitudinal section diameter of the telescopic cylinder 303c is smaller than the longitudinal section diameter of the inner cylinder 303a. The outer cylinder 303b is sleeved on the side of the outer side of the inner cylinder 303a close to the tenon head 301. The connection between the inner cylinder 303a and the telescopic cylinder 303c is located inside the outer cylinder 303b, so that the inner cylinder 303a can achieve telescopic movement under the hydraulic action of the telescopic cylinder 303c.

[0045] The telescopic cylinder sleeve 303e is sleeved on the outside of the telescopic cylinder body 303c, and one end away from the outer cylinder body 303b is abutted against the tail end inspection cover 303d. The telescopic cylinder body 303c located at the telescopic cylinder sleeve 303e is a hollow structure and is connected with one end of the hydraulic pipe 303f, so that the other end of the hydraulic pipe 303f passes through the telescopic cylinder sleeve 303e and is connected to the hydraulic pump on the power ship 100, which is used to control the supply and discharge of hydraulic oil in the telescopic cylinder sleeve 303e; wherein, the longitudinal section diameter of the telescopic cylinder sleeve 303e is equal to the longitudinal section diameter of the outer cylinder body 303b, so that when the power ship 100 is separated from the load ship 200, the outer cylinder body 303b is abutted against the telescopic cylinder sleeve 303e to control the movement stroke of the hydraulic control system 303, that is, to limit the distance between the tenon head 301 and the vertical slot plate 202.

[0046] In the specific technical solution: according to Figure 8 , Fig. 9 As shown, the support assembly 302 includes a circular tail guard plate 302a, a sleeve 302b, two wing plates 302c, two tail diagonal support plates 302d, and two groups of support lining plates 302e. The tail guard plate 302a is screwed to the tail end inspection cover 303d, and the diameter of the longitudinal section of the tail guard plate 302a is larger than the diameter of the longitudinal section of the tail end inspection cover 303d, so as to protect the hydraulic control system 303 and extend its service life; each group of the support lining plates 302e is composed of a plurality of equally spaced support lining plates 302e, which support the stability of the hydraulic control system 303 on the power ship 100, and at the same time, according to the height of the above-mentioned support lining plates 302e, the height of the hydraulic control system 303 relative to the load ship 200 is controlled;

[0047] The sleeve 302b is sleeved outside the telescopic cylinder sleeve 303e and the outer cylinder body 303b, and the opposite ends of the telescopic cylinder sleeve 303e and the outer cylinder body 303b are both located in the sleeve 302b to protect the telescopic cylinder sleeve 303e and the outer cylinder body 303b;

[0048] A wing plate 302c is integrally connected to both sides of the sleeve 302b, and the bottom of each wing plate 302c is integrally connected to a tail diagonal support plate 302d on one side close to the tail guard plate 302a, and a group of support linings 302e are integrally connected to one side close to the tenon head 301, and the angle between the support linings 302e adjacent to the tail diagonal support plate 302d is an acute angle, so as to support and limit the hydraulic control system 303.

[0049] In a further technical solution: according to Figure 8As shown, the bracket assembly 302 further includes two groups of reinforcing ribs 302f symmetrically arranged on the left and right sides of the upper end surface of the sleeve 302b, and each group of the reinforcing ribs 302f is composed of a plurality of reinforcing ribs 302f distributed at equal intervals, one end of each reinforcing rib 302f is integrally connected to the sleeve 302b, and the other end is integrally connected to the wing plate 302c on the corresponding side, so as to strengthen the connection between the sleeve 302b and the wing plate 302c, enhance its stability, and improve its life;

[0050] Furthermore, the connection surface between the reinforcing rib 302f and the sleeve 302b is an arc shape adapted thereto, so that the connection between the reinforcing rib 302f and the sleeve 302b is stable.

[0051] A plurality of arc grooves 202a are provided at equal intervals along the height direction of the vertical slot plate 202 to form a plurality of slot holes 203 in the vertical direction, so that the slot holes 203 of corresponding heights can be selected according to actual needs to be plugged into the tenon 301.

[0052] The present invention is achieved in that:

[0053] 1. When the power ship 100 needs to be connected with the load ship 200, one end of the power ship 100 is inserted into the U-shaped opening 201 of the load ship 200. At this time, the hydraulic pump is turned on to supply oil to the hydraulic control system 303, and the inner cylinder 303a is pushed to one side of the load ship 200 under the action of the hydraulic pressure, so that the tenon 301 first pushes open the slot hole 203. At this time, the vertical slot plate 202 hingedly connected to the load ship 200 is gradually pushed open, and finally the tenon 301 passes through the slot hole 203;

[0054] 2. Due to the design of the trapezoidal structure of the cross section of the tenon 301, combined with the connection method of the vertical slot plate 202 and the material properties of the slot hole 203, the tenon 301 cannot automatically detach from the slot hole 203, and at this time, the power ship 100 and the load ship 200 are connected;

[0055] 3. When it is necessary to connect or disconnect the power vessel 100 and the load vessel 200, the staff pushes the vertical slot plate 202 connected by the hinge toward the power vessel 100. At this time, the slot hole 203 gradually becomes larger to disengage the tenon 301 from the slot hole 203, thus completing the separation.

[0056] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
