[0038] The specific embodiments of the dry and liquid cargo carrying ship of the present application are described in detail below in conjunction with the drawings.

[0039] Figure 1 is a top view of the dry and liquid cargo carrying ship in the present embodiment, Figure 2 is a top view of the dry and liquid cargo carrying ship in the present embodiment, Figure 1 is a sectional view of the dry and liquid cargo carrying ship in the present embodiment along the A-A direction.

[0040] Referring to Figure 1 , Figure 2 The present embodiment provides a dry and liquid cargo carrying ship, which comprises a ship body 1, a liquid cargo cabin body 2, a dry cargo cabin body 3 and a partition cabin body 4. The ship body 1 is hollow inside. The liquid cargo cabin body 2 is arranged inside the ship body 1, and the inside of the liquid cargo cabin body 2 is used to hold liquid cargo. The dry cargo cabin body 3 is at least partially located inside the ship body 1 and above the liquid cargo cabin body 2, and the inside of the dry cargo cabin body 3 is used to store dry bulk cargo. The dry cargo cabin body 3 has a hatch opening communicating with the inside thereof. The partition cabin body 4 is arranged between the liquid cargo cabin body 2 and the dry cargo cabin body 3. The partition cabin body 4 is provided with a manhole 41 on the upper side, the manhole 41 is located outside the hatch opening of the dry cargo cabin body 3, and the manhole 41 is used to communicate with the outside of the ship body 1.

[0041] In the present application, the dry cargo cabin body 3 and the liquid cargo cabin body 2 are arranged vertically inside the ship body 1. This design makes the inside of the ship body 1 have two layers of cargo areas vertically, so that the dry and liquid cargo carrying ship can simultaneously realize the storage and transportation of dry bulk cargo and liquid cargo. This facilitates to improve the loading rate of the dry and liquid cargo carrying ship for single transportation of cargo and improve the economic benefit of transportation of cargo.

[0042] And the liquid cargo contained in the liquid cargo tank 2 is usually flammable, explosive, and corrosive, so the liquid cargo tank 2 containing the cargo is usually a dangerous area, therefore, the present application separates the dry cargo tank 3 and the liquid cargo tank 2 by arranging the isolation tank 4 between the dry cargo tank 3 and the liquid cargo tank 2, so as to isolate the dry cargo tank 3 from the dangerous area, so as to ensure that the inside of the dry cargo tank 3 is a non-dangerous area, and to ensure the safety of cargo transportation.

[0043] And the manhole 41 on the isolation tank 4 is located outside the hatch of the dry cargo tank 3, so as to ensure that the manhole 41 does not interfere with the hatch of the dry cargo tank 3, and to further isolate the dry cargo tank 3 from the dangerous area, and to ensure that the inside of the dry cargo tank 3 is a non-dangerous area.

[0044] For the convenience of description, the length direction of the ship body 1 is defined as the longitudinal direction, and the width direction of the ship body 1 is defined as the transverse direction.

[0045] Reference Figure 1 , Figure 2 The inside of the ship body 1 is hollow, and the top of the ship body 1 is provided with an opening communicating with the inside thereof.

[0046] The liquid cargo tank 2 is arranged inside the ship body 1, and the inside of the liquid cargo tank 2 is hollow to form a liquid cargo tank for containing liquid cargo. Specifically, the liquid cargo tank 2 is arranged at the lower part of the ship body 1, so that the liquid cargo tank 2 containing the liquid cargo can lower the center of gravity of the dry cargo and liquid cargo combination ship, and can improve the stability of the dry cargo and liquid cargo combination ship during navigation.

[0047] In the present embodiment, the outside of the liquid cargo tank 2 is spaced apart from the inner wall of the ship body 1 to form a lower ballast tank 5. By injecting or discharging ballast water into or from the lower ballast tank 5, the position of the center of gravity and the floating state of the dry cargo and liquid cargo combination ship can be changed, so as to ensure that the dry cargo and liquid cargo combination ship can maintain appropriate draft and stability under various loading conditions.

[0048] Specifically, the transverse sides of the liquid cargo tank 2 are each spaced apart from the inner wall of the ship body 1, that is, the transverse sides of the liquid cargo tank 2 are each surrounded by the inner wall of the ship body 1 to form a lower ballast tank 5. By injecting or discharging ballast water into or from the lower ballast tanks 5 located on the two transverse sides of the liquid cargo tank 2, the position of the center of gravity of the dry cargo and liquid cargo combination ship in the transverse direction can be adjusted, so that the dry cargo and liquid cargo combination ship can better adapt to various working conditions, and the stability of the dry cargo and liquid cargo combination ship during navigation can be improved.

[0049] The width of the lower ballast tank 5 at least meets the minimum requirement of the specification for dry cargo and liquid cargo, and is confirmed according to the specific stability evaluation. The width of the lower ballast tank 5 refers to the spacing distance between the transverse outside of the liquid cargo tank 2 and the inner wall of the ship body 1.

[0050] The bottom of the liquid cargo tank 2 and the inner side of the bottom wall of the ship body 1 are spaced apart, and a bottom ballast tank is formed. By injecting or discharging ballast water in the bottom ballast tank, the center of gravity of the dry and liquid cargo carrying ship can be changed, and the floating state can be changed, so that the dry and liquid cargo carrying ship can maintain appropriate draft and stability under various loading conditions.

[0051] The bottom ballast tank is communicated with the lower ballast tank 5, so that the center of gravity of the dry and liquid cargo carrying ship can be adjusted more flexibly, and the balance of the dry and liquid cargo carrying ship under various sailing and parking states can be ensured. Especially in the case of strong wind and waves, this design can reduce the shaking and tilting of the dry and liquid cargo carrying ship, and improve the safety of sailing. Moreover, through the communication of the bottom ballast tank and the lower ballast tank 5, the draft of the dry and liquid cargo carrying ship can be better controlled, so that the sailing performance of the dry and liquid cargo carrying ship can be optimized. In addition, the design of the communication of the bottom ballast tank and the lower ballast tank 5 can maximize the use of the space formed by the bottom ballast tank and the lower ballast tank 5, and improve the loading capacity.

[0052] The height of the bottom ballast tank at least meets the minimum requirement of the specification for dry and liquid cargo, and is confirmed according to the specific stability evaluation. The height of the bottom ballast tank refers to the spacing distance between the bottom of the liquid cargo tank 2 and the inner side of the bottom wall of the ship body 1.

[0053] In this embodiment, a partition plate 10 is arranged in the bottom ballast tank, and the partition plate 10 divides the bottom ballast tank into two independent ballast tanks 61 in the transverse direction. At this time, the two independent ballast tanks 61 are communicated with the two lower ballast tanks 5 arranged on the two sides of the liquid cargo tank 2 in the transverse direction one by one, each ballast tank 61 is communicated with the corresponding lower ballast tank 5 to form a ballast tank system 9, and the two ballast tank systems 9 are independent. By injecting or discharging ballast water in the two ballast tank systems 9 respectively, the position of the center of gravity of the dry and liquid cargo carrying ship in the transverse direction can be adjusted, so that the dry and liquid cargo carrying ship can better adapt to various working conditions, and the stability of the dry and liquid cargo carrying ship in sailing can be improved.

[0054] In this embodiment, the number of liquid cargo tanks 2 can be multiple, and the multiple liquid cargo tanks 2 are arranged in the longitudinal direction in the ship body 1. In this way, each liquid cargo tank 2 can contain one kind of liquid cargo, and the dry and liquid cargo carrying ship can simultaneously load multiple kinds of liquid cargo, so as to improve the loading rate of the transported cargo of the dry and liquid cargo carrying ship in one trip, and improve the economic benefit of the transported cargo. Specifically, the multiple liquid cargo tanks 2 are arranged closely in the longitudinal direction, so as to improve the utilization rate of the internal space of the ship body 1.

[0055] Specifically, the number of liquid cargo tanks 2 is two. In other embodiments, the two liquid cargo tanks 2 can also be distributed in the transverse direction. In other embodiments, the number of liquid cargo tanks 2 can also be one.

[0056] In this embodiment, the inner circumferential wall of the liquid cargo tank 2 is covered with an isolation coating for protecting the liquid cargo tank 2 from direct contact with the liquid cargo, thereby preventing corrosion of the inner circumferential wall of the liquid cargo tank 2. This can effectively protect the inner circumferential wall of the liquid cargo tank 2 from damage, thereby prolonging the service life of the liquid cargo tank 2 and improving the safety of the dry and liquid cargo carrying ship in operation.

[0057] The liquid cargo tank 2 is provided with a liquid inlet opening communicating with the inside of the liquid cargo tank 2. The liquid inlet opening is connected to a liquid inlet pipeline for communicating with the outside of the ship body 1. The liquid inlet pipeline can be used to transport liquid cargo into the liquid cargo tank.

[0058] Furthermore, the liquid inlet pipeline is sealingly connected to the liquid cargo tank 2 to ensure the air tightness of the liquid cargo tank. This can prevent excessive rise or fall of the pressure in the liquid cargo tank, thereby protecting the safety of the liquid cargo tank 2.

[0059] The liquid cargo tank 2 is provided with a liquid outlet opening communicating with the inside of the liquid cargo tank 2. The liquid outlet opening is connected to a liquid outlet pipeline for communicating with the outside of the ship body 1. The liquid outlet pipeline can be used to transport liquid cargo in the liquid cargo tank to the outside.

[0060] Furthermore, the liquid outlet pipeline is sealingly connected to the liquid cargo tank 2 to ensure the air tightness of the liquid cargo tank. This can prevent excessive rise or fall of the pressure in the liquid cargo tank, thereby protecting the safety of the liquid cargo tank 2.

[0061] In this embodiment, the dry cargo tank 3 is at least partially located inside the ship body 1 and above the liquid cargo tank 2. The inside of the dry cargo tank 3 is used to store dry bulk cargo. Specifically, the upper part of the dry cargo tank 3 passes through the top opening of the ship body 1 and extends upward beyond the ship body 1. The outer periphery of the upper part of the dry cargo tank 3 is sealingly fixed to the circumferential wall of the top opening of the ship body 1 to prevent rainwater or seawater from entering the inside of the ship body 1 through the gap, thereby preventing corrosion of the structures of the ship body 1, the dry cargo tank 3, etc., and ensuring the structural stability of the dry and liquid cargo carrying ship.

[0062] The lateral sides of the dry cargo tank 3 and the inner wall of the ship body 1 are respectively provided with a spacing to form an upper side ballast tank 7. By injecting or discharging ballast water into or from the upper side ballast tank 7, the center of gravity and the floating state of the dry and liquid cargo carrying ship can be changed to ensure that the dry and liquid cargo carrying ship can maintain appropriate draft and stability under various loading conditions.

[0063] In this embodiment, the upper ballast tank 7 is communicated with the lower ballast tank 5. At this time, the upper ballast tank 7, the lower ballast tank 5 and the ballast empty tank 61 located at the same lateral side are communicated to form a ballast tank system 9, so that the unified injection or discharge of the ballast water operation of the ballast tank system 9 located at the same lateral side is facilitated, the operation process is simplified, and the position of the center of gravity of the dry cargo and liquid cargo combined ship can be adjusted more flexibly.

[0064] Figure 3 The schematic view of the transverse section of the dry cargo and liquid cargo combined ship in other embodiments.

[0065] Reference Figure 3 In other embodiments, the lower part of the dry cargo tank body 3 along the lateral sides is attached to the inner wall of the ship body 1. The upper part of the dry cargo tank body 3 along the lateral sides is spaced from the inner wall of the ship body 1 and forms a top ballast tank 8. The lower part of the lateral wall of the dry cargo tank body 3 can be independent of the inner wall of the ship body 1 or can be coincident and shared. The specific arrangement is determined according to the needs and is not limited herein.

[0066] Reference Figure 1 , Figure 2 The number of dry cargo tank bodies 3 can be multiple, and the multiple dry cargo tank bodies 3 are distributed longitudinally, so that each dry cargo tank body 3 can contain one kind of dry bulk cargo for classified loading of dry bulk cargo, improving the loading and unloading efficiency, and enabling the dry cargo and liquid cargo combined ship to simultaneously load multiple kinds of dry bulk cargo, thereby facilitating the improvement of the loading rate of goods transported by the dry cargo and liquid cargo combined ship in a single trip and improving the economic benefits of the transported goods. Specifically, the multiple dry cargo tank bodies 3 are arranged longitudinally adjacent to each other, so as to improve the utilization rate of the internal space of the ship body 1. In other embodiments, two dry cargo tank bodies 3 can also be distributed laterally.

[0067] In this embodiment, the dry cargo tank body 3 is provided with a hatch communicating with the inside thereof, and the hatch is communicated with the outside of the ship body 1, so that the loading or unloading operation of the dry cargo tank body 3 can be realized through the hatch.

[0068] The hatch of the dry cargo tank body 3 is provided with a hatch cover 11, and the hatch cover 11 is detachably connected with the dry cargo tank body 3 and is used to open and close the hatch. At this time, the top of the dry cargo tank body 3 is designed to protrude upward beyond the ship body 1, so as to facilitate the operation of the hatch cover 11 on the top of the ship body 1 to open and close the hatch cover 11. In this embodiment, the lower part of the dry cargo tank body 3 has a larger cross-sectional area than the area of the hatch cover 11. Specifically, the lower part of the dry cargo tank body 3 along the two ends of the lateral sides corresponds to and is flush with the two ends of the lateral sides of the hatch cover 11, and the two ends of the lower part of the dry cargo tank body 3 along the longitudinal direction both protrude outward beyond the hatch cover 11.

[0069] The hatch cover 11 is sealingly connected with the dry cargo hold body 3 to seal the hatch opening of the dry cargo hold body 3, so as to prevent external water from entering the dry cargo hold body 3 through the gap, protect the dry bulk cargo in the dry cargo hold body 3 from being wetted and damaged, and maintain the dryness and integrity of the dry bulk cargo during transportation; and also prevent seawater from entering the dry cargo hold body 3 to corrode the internal structure of the dry cargo hold body 3, and protect the structural integrity of the dry cargo hold body 3.

[0070] For example, the inner side of the hatch cover 11 is circumferentially provided with a sealing strip, which is in pressure contact with the top of the dry cargo hold body 3 when the hatch cover 11 is closed at the hatch opening, so as to seal the gap between the hatch cover 11 and the top of the dry cargo hold body 3.

[0071] In this embodiment, the isolation hold body 4 is arranged between the liquid cargo hold body 2 and the dry cargo hold body 3. Since the liquid cargo contained in the liquid cargo hold body 2 is usually flammable, explosive, corrosive and dangerous, the isolation hold body 4 is used to separate the dry cargo hold body 3 and the liquid cargo hold body 2, so as to isolate the dry cargo hold body 3 from the dangerous area and ensure that the interior of the dry cargo hold body 3 is a non-dangerous area, thereby ensuring the safety of cargo transportation.

[0072] The projection of the isolation hold body 4 on the liquid cargo hold body 2 covers the liquid cargo hold body 2 in the vertical direction, so as to completely isolate the liquid cargo hold body 2 and the dry cargo hold body 3, and ensure that the interior of the dry cargo hold body 3 is a non-dangerous area, thereby ensuring the safety of cargo transportation. It should be noted that the number of isolation hold bodies 4 can be multiple, in which case the multiple isolation hold bodies 4 are arranged one-to-one with the multiple liquid cargo hold bodies 2. The number of isolation hold bodies 4 can also be one, in which case the isolation hold body 4 covers all the liquid cargo hold bodies 2.

[0073] The horizontal end of the isolation hold body 4 is flush with the horizontal end of the liquid cargo hold body 2, and the horizontal end of the isolation hold body 4 has a spacing with the inner wall of the ship body 1 in the horizontal direction, so that the upper ballast tank 7 and the lower ballast tank 5 are communicated through the spacing. The above design enables the isolation hold body 4 to separate the dry cargo hold body 3 and the liquid cargo hold body 2 while avoiding occupying the space of the ballast tank system 9, so as to maximize the space of the ballast tank system 9.

[0074] The isolation hold body 4 is hollow, and a manhole 41 is arranged on the isolation hold body 4 and communicates with the interior of the isolation hold body 4. The manhole 41 is located outside the hatch opening of the dry cargo hold body 3 and is used to communicate with the outside of the ship body 1, so that the staff can enter and exit the interior of the isolation hold body 4 through the manhole 41. The manhole 41 is arranged outside the hatch opening of the dry cargo hold body 3, so as to ensure that the manhole 41 does not interfere with the hatch opening of the dry cargo hold body 3, and further isolate the dry cargo hold body 3 from the dangerous area and ensure that the interior of the dry cargo hold body 3 is a non-dangerous area.

[0075] Specifically, the manhole 41 is located at the transverse end of the isolation cabin 4 and is located outside the hatch cover 11 in the longitudinal direction.

[0076] In the embodiment, the isolation cabin 4 is provided with a manhole 41 at each of the two transverse ends, so that the staff can enter and exit the isolation cabin 4 through any manhole 41.

[0077] The ship body 1 is also provided with a walkway wall 12, which forms a walking channel 13 together with the inner wall of the ship body 1 and / or the dry cargo cabin 3, covers the manhole 41 of the isolation cabin 4 and extends upward to the top of the ship body 1, and the walking channel 13 is used to connect the manhole 41 and the upper part of the ship body 1. Specifically, the walkway wall 12 is arranged at the transverse end of the isolation cabin, and is located outside the hatch cover 11 in the longitudinal direction. At this time, the walkway wall 12 forms the walking channel 13 together with the inner wall of the ship body 1, and the longitudinal side wall of the walkway wall 12 forms an upper ballast tank 7 together with the outer side of the dry cargo cabin 3 and the inner wall of the ship body 1. That is, the walkway wall 12 is arranged in the space between the dry cargo cabin 3 and the inner wall of the ship body 1 in the transverse direction, which can improve the utilization rate of the internal space of the ship body 1 and improve the structural compactness of the dry cargo and liquid cargo carrying ship. In addition, the above design also makes it not easy to block the walking channel 13 when the hatch cover 11 is opened, so that the walking channel 13 can remain unblocked.

[0078] In the embodiment, the liquid inlet pipeline and the liquid outlet pipeline can be arranged in the isolation cabin 4 to fully utilize the internal space of the isolation cabin 4.

[0079] From the above technical solution, the utility model has at least the following advantages and positive effects:

[0080] In the application, the dry cargo cabin and the liquid cargo cabin are arranged in the ship body in the up-down direction. This design makes the ship body have two layers of cargo areas in the up-down direction, so that the dry cargo and liquid cargo carrying ship can simultaneously realize the storage and transportation of dry bulk cargo and liquid cargo. This can improve the loading rate of the dry cargo and liquid cargo carrying ship for single transportation of goods and improve the economic benefits of transportation of goods.

[0081] In addition, the liquid cargo in the liquid cargo cabin usually has the risk of being flammable, explosive and corrosive, so the liquid cargo cabin loaded with goods is usually a dangerous area. Therefore, the application separates the dry cargo cabin and the liquid cargo cabin by arranging the isolation cabin between the dry cargo cabin and the liquid cargo cabin, so as to isolate the dry cargo cabin from the dangerous area. This can ensure that the interior of the dry cargo cabin is a non-dangerous area, so as to ensure the safety of transportation of goods.

[0082] And, the manhole on the isolation cabin is located outside the hatch of the dry cargo cabin, so that the manhole and the hatch of the dry cargo cabin do not interfere with each other, the dry cargo cabin can be further isolated from the dangerous area, and the inside of the dry cargo cabin is a non-dangerous area.
