[0002] At present, in a propulsion device that uses the reaction force generated by jetting high-speed gas, the flow guiding groove that needs to be used is an important structure for guiding the airflow direction. It is a facility that discharges the airflow out of the tunnel according to the designed direction to prevent the airflow from flowing back or rushing towards the ground, so as to eliminate the damage to surrounding facilities. At present, the main structure of the flow guiding groove is mostly a reinforced concrete structure, which requires digging a certain space downward on a flat ground, setting up a steel reinforcement cage, and being put into use after natural curing after pouring.

[0003] In the prior art, since ships are built of steel, and steel has the characteristics of high strength, good toughness, and strong plasticity, ships are selected as the design platform for the flow guiding groove. However, this makes the ships only used as a sea launch platform, and the functions are relatively single. Summary of the Utility Model

[0004] In order to solve the technical problem in the prior art that ships are selected as the design platform for the flow guiding groove, but the functions of the ships are relatively single, a ship is provided.

[0011] In some embodiments of the present application, a second sunk platform recessed towards one side of the flow guiding groove is provided at the edge of the exhaust port, and the second hatch cover body is detachably installed at the second sunk platform.

[0012] In some embodiments of the present application, the hull includes a plurality of watertight compartments, and the watertight bulkheads are used to divide the interior of the hull into independent accommodation spaces. The bulkheads of at least one of the watertight compartments enclose to form a diversion channel.

[0013] In some embodiments of the present application, the hull further includes a load-bearing support structure, which is arranged below the deck and between the air inlet and the exhaust outlet. The load-bearing support structure is connected between the bulkheads of the watertight compartments and is used to support the object to be launched.

[0014] In some embodiments of the present application, one end of the load-bearing support structure close to the air inlet is arranged below the first sunken platform at the air inlet to support part of the weight of the first hatch cover.

[0015] In some embodiments of the present application, one end of the load-bearing support structure close to the exhaust outlet is arranged below the second sunken platform at the exhaust outlet to support part of the weight of the second hatch cover.

[0016] In some embodiments of the present application, the load-bearing support structure is configured as a box-shaped load-bearing beam.

[0017] In some embodiments of the present application, the watertight compartment forming the diversion channel is provided with diversion ribs. The diversion ribs are located below the air inlet and extend from the bottom of the watertight compartment towards the side where the air inlet is located. The diversion ribs are used to divide the interior of the diversion channel into a first diversion channel and a second diversion channel. The first diversion channel communicates with the air inlet and one of the exhaust outlets, and the second diversion channel communicates with the air inlet and the other exhaust outlet, so that the air flow at the air inlet can flow along the first diversion channel and the second diversion channel respectively and exhaust through the corresponding exhaust outlets.

[0018] In some embodiments of the present application, the hull includes a bottom support structure, which is arranged below the watertight compartment and is used to support the watertight compartment. The upwardly protruding part of the bottom support structure forms the diversion ribs.

[0019] In some embodiments of the present application, the top of the diversion rib facing the air inlet forms a pointed end portion. The first diversion channel and the second diversion channel are respectively arranged on both sides of the pointed end portion. The air flow at the air inlet flows towards the first diversion channel and the second diversion channel respectively after passing through the pointed end portion.

[0041] Figure 1 It is the top view of a ship in an embodiment of the application; Figure 2It is one of the partial structural sectional views of a ship in an embodiment of the application.

[0042] Please refer to the appendix Figure 1 and the appendix Figure 2 As shown, the present application provides a ship, which includes a hull 1, a deck 2, and a hatch cover.

[0043] Among them, a diversion channel 101 is provided inside the hull 1. The hull 1 is the main structure of the ship and usually includes parts such as a ship's hull, a framework, a deck 2, and cabins. Among them, by utilizing the space inside the transportation ship and the characteristics of high strength and good toughness of the steel material in the hull 1, a diversion channel 101 is provided inside the hull 1 to realize the function of the sea-launch propulsion device.

[0044] As Figure 1 shown, in some specific embodiments, the diversion channel 101 is arranged near the tail of the hull 1. Among them, since the stress and deformation received by the stern part are relatively small, by arranging the diversion channel 101 near the tail of the hull 1, the integrity and stability of the stern structure can be maintained, and the adverse impact on the longitudinal strength of the hull 1 can be reduced.

[0045] The deck 2 is arranged on the hull 1 and is located above the diversion channel 101. The deck 2, as the upper structure of the ship, is used to carry personnel, equipment, and goods.

[0046] As Figure 2 shown, the deck 2 is provided with an air inlet 201 and exhaust ports 202 spaced on both sides of the air inlet 201. The air inlet 201 and the exhaust ports 202 are connected through the diversion channel 101. The air inlet 201 is used for air flow to pass through and discharge along the diversion channel 101 to the exhaust ports 202. In this way, the flow channel of the diversion channel 101 and the air inlet 201 and the exhaust ports 202 on the deck 2 together form an efficient air flow channel system. By placing the air inlet 201 between the two exhaust ports 202, the propulsion device can be installed above the air inlet 201. When launching the propulsion device, the high-temperature air flow generated by the propulsion device using the reaction force generated by jetting high-speed gas can enter the diversion channel 101 through the air inlet 201, and then under the guiding action of the diversion channel 101, it can be discharged evenly and smoothly through the exhaust ports 202 on both sides.

[0047] In some embodiments, the exhaust ports 202 are respectively arranged on the longitudinal sides of the air inlet 201. Among them, taking the center line of the exhaust port 202 as the boundary, the transverse direction of the hull 1 is divided into two regions, and the area of one region is larger than that of the other region.

[0048] As Figure 1As shown, it should be noted that the longitudinal sides of the air inlet 201 are aligned with the length direction of the hull 1. The exhaust ports 202 are respectively arranged on the longitudinal sides of the air inlet 201, that is, the exhaust ports 202 are located on the front and rear sides of the air inlet 201, and their arrangement is along the length direction of the hull 1.

[0049] Among them, taking the center line of the exhaust port 202 as the boundary, the hull 1 is transversely divided into two regions, and the area of one region is larger than that of the other region, so that a larger area region is formed between the exhaust port 202 and one side of the hull 1, which can be used as a passage for cargo transportation.

[0050] Specifically, please refer to the appendix Figure 2 As shown, taking the center line of the exhaust port 202 as the boundary, the hull 1 is transversely divided into upper and lower regions, and the area of the upper region is larger than that of the lower region.

[0051] In a specific setting, the larger area region can be set according to whether the left or right side of the ship is close to the dock, so that even when the hatch cover is not installed, the passage space for the transport vehicle on the deck 2 can be ensured.

[0052] Figure 3 It is the second partial structural sectional view of the ship in an embodiment of the application.

[0053] Please refer to the appendix Figure 3 As shown, the hatch cover includes a first hatch cover body 31, and the first hatch cover body 31 is detachably covered at the air inlet 201 to cover the air inlet 201.

[0054] The hatch cover further includes a second hatch cover body 32, and the second hatch cover body 32 is detachably covered at the exhaust port 202 to cover the exhaust port 202.

[0055] Specifically, the hatch cover includes a first hatch cover body 31 and a second hatch cover body 32, and the first hatch cover body 31 and the second hatch cover body 32 are respectively detachably covered at the air inlet 201 and the exhaust port 202.

[0056] It should be noted that when a sea launch mission needs to be carried out, the first hatch cover body 31 and the second hatch cover body 32 can be removed to expose the air inlet 201 and the exhaust port 202; when the sea launch mission is not carried out, the first hatch cover body 31 and the second hatch cover body 32 are respectively covered on the air inlet 201 and the exhaust port 202, which can not only close the hatch cover to prevent rain or sundries from entering the interior of the hull 1, but also enable the ship to return to the conventional sea transportation state. By setting the hatch cover, the ship can flexibly switch between a sea launch platform and a cargo transport ship, improving the comprehensive application ability and usage efficiency of the ship.

[0057] Figure 4 It is the top view of the flow guiding groove structure in an embodiment of the application.

[0058] Please refer to the attached Figure 2 and the attached Figure 4 As shown, in some embodiments, a first sunk platform 102 that is recessed towards one side of the diversion groove 101 is provided at the edge of the air inlet 201, and the first hatch body 31 is detachably installed at the first sunk platform 102. Among them, the first sunk platform 102 can provide a stable installation foundation for the first hatch body 31. Moreover, when the first hatch body 31 is installed at the first sunk platform 102, its edge can closely fit the edge of the first sunk platform 102 to prevent air flow or moisture from seeping in through the gap. On the other hand, since the first hatch body 31 can be directly installed on the first sunk platform 102 without additional fixing devices or complex operation steps, the installation and disassembly process of the first hatch body 31 is simplified.

[0059] A second sunk platform 103 that is recessed towards one side of the diversion groove 101 is provided at the edge of the exhaust port 202, and the second hatch body 32 is detachably installed at the second sunk platform 103. Among them, the second sunk platform 103 can provide a stable installation foundation for the second hatch body 32. Moreover, when the second hatch body 32 is installed at the second sunk platform 103, its edge can closely fit the edge of the second sunk platform 103 to prevent air flow or moisture from seeping in through the gap. On the other hand, since the second hatch body 32 can be directly installed on the second sunk platform 103 without additional fixing devices or complex operation steps, the installation and disassembly process of the second hatch body 32 is simplified.

[0060] It can be understood that the first sunk platform 102 and the second sunk platform 103 can be formed by being recessed downward from the deck 2.

[0061] As Figure 3 shown, more specifically, the depth of the first sunk platform 102 can correspond to the thickness of the first hatch body 31, so that after the first hatch body 31 is set in the first sunk platform 102, the upper surface of the first hatch body 31 can be flush with the surface of the deck 2, which is convenient for carrying personnel, equipment, goods, etc.

[0062] Similarly, the depth of the second sunk platform 103 can correspond to the thickness of the second hatch body 32, so that after the second hatch body 32 is set in the second sunk platform 103, the upper surface of the second hatch body 32 can be flush with the surface of the deck 2, which is convenient for carrying personnel, equipment, goods, etc.

[0063] As Figure 3As shown, in some embodiments, the hull 1 includes a plurality of watertight compartments 4. The bulkheads of the watertight compartments 4 are used to divide the interior of the hull 1 into independent accommodation spaces. Among them, each of the watertight compartments 4 is separated by the bulkhead of the watertight compartment 4, and each watertight compartment 4 can form an independent accommodation space. Moreover, since the bulkhead of the watertight compartment 4 can prevent water from flowing from one compartment into another, the watertight compartment 4 can maintain a certain buoyancy and stability when the hull 1 encounters damage or other emergencies.

[0064] Furthermore, the bulkhead of at least one of the watertight compartments 4 encloses to form a diversion groove 101. In this way, the bulkhead of the watertight compartment 4 can provide an additional protective barrier for the diversion groove 101. Moreover, by arranging the diversion groove 101 inside the watertight compartment 4, the internal layout of the ship can be optimized, and the mutual influence between the propulsion device and other ship systems (such as the power system, control system, etc.) can be minimized.

[0065] In particular, one of the watertight compartments 4 is provided with a diversion groove 101.

[0066] As Figure 3 and Figure 4 shown, in some embodiments, the hull 1 further includes a load-bearing support structure 5. Among them, the load-bearing support structure 5 can be arranged below the deck 2 and located between the air inlet 201 and the exhaust port 202. The load-bearing support structure 5 is connected between the bulkheads of the watertight compartments 4, and the load-bearing support structure 5 is used to support the object to be launched.

[0067] Specifically, the object to be launched can specifically refer to a propulsion device that generates a reaction force by ejecting high-speed gas. Generally, the propulsion device is arranged above the air inlet 201. By locating the load-bearing support structure 5 between the air inlet 201 and the exhaust port 202, it can support the propulsion device arranged above, provide a stable launch platform for the propulsion device, and improve the stability and reliability during the launch process.

[0068] As Figure 3 shown, there are two load-bearing support structures 5, and the two load-bearing support structures 5 are respectively arranged on both sides of the air inlet 201.

[0069] One end of the load-bearing support structure 5 close to the air inlet 201 is arranged below the first sunk platform 102 at the air inlet 201 to support part of the weight of the first hatch cover 31. In this way, the load-bearing support structure 5 can directly support part of the weight of the first hatch cover 31, thereby reducing the pressure of the first hatch cover 31 on the deck 2 and other structures of the hull 1.

[0070] Similarly, one end of the load-bearing support structure 5 close to the exhaust port 202 can be arranged below the second sunken platform 103 at the exhaust port 202 to support part of the weight of the second hatch cover 32. In this way, the load-bearing support structure 5 can directly support part of the weight of the second hatch cover 32, thereby reducing the pressure of the second hatch cover 32 on the deck 2 and other structures of the hull 1.

[0071] More specifically, the load-bearing support structure 5 can be configured as a box-shaped load-bearing beam.

[0072] Among them, the box-shaped load-bearing beam is a beam structure with a closed cross-section, and its cross-sectional shape is usually rectangular or trapezoidal, etc., which can provide excellent bending resistance, torsion resistance and shear resistance to further improve the overall strength and stability of the ship structure. Moreover, choosing the box-shaped load-bearing beam as the load-bearing support structure 5 is conducive to making the load on the deck 2 more evenly distributed on the beam body, thereby reducing the occurrence of stress concentration.

[0073] As Figure 3 shown, the watertight compartment 4 forming the diversion groove 101 is provided with diversion ribs 6. The diversion ribs 6 are located below the air inlet 201, and the diversion ribs 6 extend from the bottom of the watertight compartment 4 towards the side where the air inlet 201 is located. In this way, the diversion ribs 6 can directly play a role in guiding the airflow entering the air inlet 201.

[0074] Specifically, the diversion ribs 6 are used to divide the interior of the diversion groove 101 into a first diversion channel 1011 and a second diversion channel 1012. The first diversion channel 1011 communicates with the air inlet 201 and one of the exhaust ports 202, and the first diversion channel 1011 communicates with the air inlet 201 and the other exhaust port 202, so that the airflow at the air inlet 201 can flow along the first diversion channel 1011 and the second diversion channel 1012 respectively and exhaust through the corresponding exhaust port 202.

[0075] It should be noted that by arranging the diversion ribs 6 to divide the diversion groove 101 into two independent channels, the first diversion channel 1011 and the second diversion channel 1012 respectively communicate with one of the exhaust ports 202. Under the guidance of the diversion ribs 6, the airflow at the air inlet 201 can be effectively divided into two streams and flow along the first diversion channel 1011 and the second diversion channel 1012 respectively. Then, these two streams of airflow are discharged through the corresponding exhaust ports 202 respectively, making the exhaust process more efficient and orderly, and thus realizing the smooth guiding and effective discharge of the airflow.

[0076] As Figure 2 and Figure 3 shown, the hull 1 includes a bottom support structure 7. The bottom support structure 7 is arranged below the watertight compartment 4. The bottom support structure 7 is used to support the watertight compartment 4, and the upwardly convex part of the bottom support structure 7 forms the diversion ribs 6.

[0077] Among them, the bottom support structure 7, as an important part of the hull 1, is arranged below the watertight cabin 4, provides a stable support for the watertight cabin 4, can enhance the bottom support strength of the watertight cabin 4, is beneficial to improving the structural stability and compressive capacity of the entire hull 1, and improves the stability and safety of the ship under complex sea conditions.

[0078] The upwardly convex part of the bottom support structure 7 forms the flow guiding rib 6. As a part of the bottom support structure 7, the flow guiding rib 6 can also bear a certain air flow pressure, further ensuring the stable operation of the flow guiding groove 101. Moreover, the flow guiding rib 6 is directly formed by the bottom support structure 7, which can reduce the need for installing an additional flow guiding rib 6 and simplifies the construction and maintenance process of the hull 1.

[0079] As Figure 2 shown, in some embodiments, the top of the flow guiding rib 6 facing the air inlet 201 forms a pointed end 61, the first flow guiding channel 1011 and the second flow guiding channel 1012 are respectively arranged on both sides of the pointed end 61, and the air flow of the air inlet 201 flows to the first flow guiding channel 1011 and the second flow guiding channel 1012 respectively after passing through the pointed end 61.

[0080] In this way, by forming the pointed end 61 at the top of the flow guiding rib 6 facing the air inlet 201, the air flow can contact the pointed end 61 after entering the air inlet. The pointed end 61 can efficiently guide the fluid to change direction, which helps to more evenly distribute the air flow of the air inlet 201 to the first flow guiding channel 1011 and the second flow guiding channel 1012 on both sides, is beneficial to reducing the formation of vortices and turbulences during the flow of the air flow through the flow guiding groove 101, and improves the stability and controllability of the air flow in the flow guiding groove 101.

[0081] Among them, the extending directions of the first flow guiding channel 1011 and the second flow guiding channel 1012 are arranged along the length direction of the hull 1. This makes it more convenient to set the length of the flow guiding groove 101 and is beneficial to longer-distance air flow transportation.

[0082] Specifically, as Figure 2 shown, the cross-sectional view of the flow guiding rib 6 is triangular, and the pointed end 61 is located at the top of the flow guiding rib 6. The length of the pointed end 61 of the flow guiding rib 6 extends along the width direction of the hull 1, so that the first flow guiding channel 1011 and the second flow guiding channel 1012 are arranged along the length direction of the hull 1.

[0083] In some embodiments, the overall shape of the flow guiding groove 101 is "W"-shaped.

[0084] As Figure 2 and Figure 3As shown, in some embodiments, the flow guiding rib 6 has first flow guiding surfaces 601 disposed on both sides of the tip portion 61. The first flow guiding surfaces 601 are inclined downward from the tip portion 61 toward the side close to the exhaust port 202, and the connection between the first flow guiding surfaces 601 and the bottom wall of the flow guiding groove 101 is in an arc transition.

[0085] Among them, by inclining the first flow guiding surfaces 601 downward from the tip portion 61 toward the side close to the exhaust port 202, the inclined design enables the fluid to flow naturally along the direction of the flow guiding surface when it contacts the flow guiding surface, thereby reducing the resistance and turbulence of the fluid flow, which is beneficial to guiding the air flow entering the flow guiding groove 101 through the air inlet 201 to transition more smoothly from the tip portion 61 to the exhaust port 202; moreover, the arc transition design between the first flow guiding surfaces 601 and the bottom wall of the flow guiding groove 101 can reduce the turbulence and eddy current generated when the fluid flows through this area, thereby reducing energy loss and noise. Moreover, the arc transition can also improve the strength and durability of the structure and reduce the risk of damage caused by stress concentration.

[0086] As Figure 3 shown, in some embodiments, the flow guiding groove 101 is provided with second flow guiding surfaces 602. The second flow guiding surfaces 602 are inclined from the bottom wall of the flow guiding groove 101 toward the exhaust port 202, and the connection between the second flow guiding surfaces 602 and the bottom wall of the flow guiding groove 101 is in an arc transition.

[0087] Among them, the inclined second flow guiding surfaces 602 can provide an upward path for the fluid, enabling the fluid to flow smoothly along the second flow guiding surfaces 602 toward the exhaust port 202. Moreover, similar to the first flow guiding surfaces 601, the connection between the second flow guiding surfaces 602 and the bottom wall of the flow guiding groove 101 also adopts an arc transition, which can reduce the turbulence or eddy current generated when the air flow passes through this area, enabling the fluid to maintain a stable flow state when flowing through this area and avoiding the impact and vibration caused by a sudden change in direction.

[0088] Although the present utility model has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present utility model can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be broadly interpreted within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
