Description

Technical Field

[0001] This utility model relates to the field of modular boat technology, specifically a portable modular boat. Background Technology

[0002] Modular assembly ships are vessels designed using a modular approach, consisting of several compartment units connected sequentially from front to back, as illustrated in the existing patent with publication number CN102897283A. Disassembling these units reduces the length of space required for storage, facilitating transportation and carrying. However, the buoyancy of each compartment unit in existing modular ships is fixed. When these units are assembled, assembly issues or manufacturing precision can lead to inconsistent drafts between different compartment units. This results in significant torsional stress at the connection points between adjacent compartment units, potentially causing structural deformation or even breakage at the joint. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a portable modular boat that can adjust the draft of different compartment units to keep the draft of different compartment units as consistent as possible, reduce torsional stress at the connection points, and ensure service life.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A portable modular boat includes several compartment units connected sequentially from front to back by bolts. The compartment units adopt a double-layer structure. Each compartment unit includes an outer compartment, an inner compartment disposed inside the outer compartment, and a cavity located between the outer compartment and the inner compartment. Each compartment unit is provided with a water inlet communicating with the cavity.

[0005] Preferably, the plurality of cargo compartment units include a bow and a stern.

[0006] Preferably, one or more hull sections are provided between the bow and the stern of the ship.

[0007] Preferably, the top left and right sides of the top of the silo unit are provided with flanges extending outwards, wherein the rear end of the flange of the foremost silo unit, the front end of the flange of the last silo unit, and the front and rear ends of the flanges of the remaining silo units are provided with downward-extending upper bolt mounting positions.

[0008] Preferably, each of the upper bolt mounting positions is provided with a lower bolt mounting position below it. The lower bolt mounting position is located at the corner between the side and bottom of the silo unit, and the silo unit is provided with a bolt mounting clearance groove that is adapted to the lower bolt mounting position.

[0009] Preferably, in two adjacent storage units, one storage unit has a plurality of connecting blocks vertically arranged at its connecting end, and the other storage unit has a connecting groove adapted to the connecting blocks vertically arranged at its connecting end.

[0010] Preferably, in two adjacent storage units, the top of the connecting end of the storage unit with the connecting block has an overlapping portion extending outward, and the top of the connecting end of the storage unit with the connecting groove has an overlapping groove adapted to the overlapping portion.

[0011] Preferably, the bolt is a hand-tightening bolt.

[0012] Preferably, the bottom surface of the storage unit is provided with a flow guide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The container unit of this utility model adopts a double-layer structure with a cavity reserved between the inner and outer layers. Water can be injected into the cavity through the water inlet to adjust the draft of the container unit, so that the draft of different container units is as consistent as possible, reducing torsional stress at the connection and ensuring service life. In addition, the existence of the cavity can also provide buoyancy for the container unit, ensuring that the hull does not sink in the event of capsizing. Attached Figure Description

[0022] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0023] Example: As attached Figures 1-7 This utility model describes a portable modular boat, comprising several compartment units 1 connected sequentially from front to back by bolts. The compartment units 1 can be made of plastic and are integrally molded. Each compartment unit 1 has a double-layer structure, including an outer compartment 11, an inner compartment 12 located inside the outer compartment 11, and a cavity 13 located between the outer compartment 11 and the inner compartment 12. Gaps are left on the bottom and sides of the outer compartment 11 and the inner compartment 12 to form the cavity 13, and the top of the cavity 13 is closed. The outer compartment 11, the inner compartment 12, and the sealing plate at the top of the cavity 13 are integrally molded. Each compartment unit 1 has a water inlet 14 communicating with the cavity 13. The water inlet 14 consists of a water inlet hole and a water inlet plug, and is located on the sealing plate. The sealing plate has a threaded hole as a water inlet hole, and the water inlet plug has corresponding external threads.

[0024] In use, this utility model allows for the adjustment of the draft depth of the chamber unit 1 by injecting water into the cavity 13 of the chamber unit 1, so that the draft depth of different chamber units is kept as consistent as possible, thereby reducing the torsional stress at the connection between two adjacent chamber units 1 and ensuring service life.

[0025] The number of cargo unit 1 can be set as needed. Several cargo unit 1 include bow, stern and hull. Depending on the required length of the hull, only one bow and one stern can be set, or one or more hull sections can be arranged between the bow and one stern.

[0026] In traditional modular ships, the connection holes of the hull are located on the front or rear end face of the hull. When installing bolts, the sealing of the bolt connection needs to be considered to prevent water leakage from the hull.

[0027] Preferably, to facilitate bolt installation, the top left and right sides of the top of the hopper unit 1 are provided with outwardly extending flanges 15. The rear end of the flange 15 at the frontmost end of the hopper unit 1, the front end of the flange 15 at the rearmost end of the hopper unit 1, and the front and rear ends of the remaining flanges 15 of the hopper unit 1 are provided with downwardly extending upper bolt mounting positions 16. The upper bolt mounting positions 16 are connecting plates with bolt mounting holes 24. The hopper unit 1, the flanges 15, and the upper bolt mounting positions 16 adopt an integrated structure. The bolts are installed on the upper bolt mounting positions 16, which facilitates bolt installation. Moreover, the bolts are located on the outside of the hopper unit 1, which avoids drilling holes in the body of the hopper unit 1 and avoids the problem of water leakage in the hopper unit 1. This solves the problem of easy water leakage in traditional connection hole positions.

[0028] Furthermore, each of the upper bolt mounting positions 16 is provided with a lower bolt mounting position 17 below it. The lower bolt mounting position 17 is located at the corner between the side and bottom of the tank unit 1, and the tank unit 1 is provided with a bolt mounting clearance groove 18 adapted to the lower bolt mounting position 17. The clearance groove 18 is provided at a certain distance from the end face of the tank unit 1 at the corner between the side and bottom of the tank unit 1. The clearance groove 18 and the end face form the lower bolt mounting position 17. The width of the lower bolt mounting position 17 is equal to the width of the upper bolt mounting position 16. The lower bolt mounting position 17 is provided with a bolt mounting hole 24 for mounting bolts. The length of the clearance groove 18 is greater than the length of the bolt, and the depth of the clearance groove 18 is not less than 1.5 times the outer diameter of the bolt head, which can ensure that there is no protrusion on the underwater part of the outer side of the tank unit 1.

[0029] Preferably, in order to improve the stability of the connection between two adjacent storage units, one of the adjacent storage units 1 has a plurality of connecting blocks 19 vertically arranged at the connection end, and the other storage unit 1 has a connecting groove 20 adapted to the connecting blocks 19 vertically arranged at the connection end. The connection end is the end of the two adjacent storage units 1 that is close to each other. The cross-section of the connecting block 19 can be rectangular, T-shaped or other shapes.

[0030] Furthermore, in two adjacent compartment units 1, the top of the connecting end of the compartment unit 1 with connecting block 19 is provided with an outwardly extending overlapping portion 21, and the top of the connecting end of the compartment unit 1 with connecting groove 20 is provided with an overlapping groove 22 adapted to the overlapping portion 21. When connecting two adjacent compartment units 1, the connecting block 19 is inserted into the connecting groove 20 from top to bottom until the overlapping portion 21 is placed in the overlapping groove 22. At this time, it can be ensured that the upper surface of the combined ship hull is in a horizontal state, and the bolt mounting holes 24 on the two adjacent compartment units 1 can be aligned, which facilitates the installation of bolts.

[0031] Preferably, in order to facilitate manual assembly of this utility model, the bolt is a hand-tightening bolt, which can be a wing bolt or a hand-tightening bolt with a knob on the bolt head.

[0032] Preferably, the bottom surface of the cargo compartment unit 1 is provided with a flow guide groove 23, which can reduce the resistance of the ship.
