When the inner cabin of the cargo ship is needed to transport grain, the grain needs to be placed in the cavity. However, when a large amount of grain is stored inside the cavity, the temperature inside the cavity will continue to rise as the grain respiration proceeds, thereby affecting the quality of the grain. Summary of the Invention

[0003] In view of this, an object of the present invention is to provide a ship with a granary cooling device, which has the advantage of being able to cool down the grain when transporting the grain and is not likely to affect the quality of the grain.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a ship with a granary cooling device, comprising a hull, a grain transport tank for storing grain is provided inside the hull; a water inlet tank and a water outlet tank are provided inside the hull, and the water inlet tank and the water outlet tank are respectively arranged on the left and right sides of the grain transport tank; a pumping device is provided on the side of the water inlet tank away from the grain transport tank, and the pumping device is used to pump seawater into the water inlet tank; a water supply pipe is connected between the water inlet tank and the grain transport tank, and a water supply valve is provided in the water supply pipe; a drain pipe is connected between the water outlet tank and the grain transport tank, and a drain valve is provided in the drain pipe; a drainage device is provided on the side of the water outlet tank away from the grain transport tank, and the drainage device is used to pump seawater out of the water outlet tank; a cooling pipe is provided in the grain transport tank, and both ends of the cooling pipe are respectively connected to the water supply pipe and the drainage pipe.

[0005] According to the above technical solution, when the above-mentioned ship is needed to transport grain, one end of the cooling pipe is fixedly connected to the water supply pipe, and the other end of the cooling pipe is fixedly connected to the drain pipe. The water supply valve is opened to connect the water inlet tank with the cooling pipe. The drain valve is opened to connect the cooling pipe with the drain chamber. The pumping device is opened to pump seawater into the water inlet tank. The water in the water inlet tank can enter the water outlet tank through the cooling pipe under pressure. The drain device is opened to pump seawater out of the water outlet tank. As seawater continuously flows through the cooling pipe, it cools the grain in the grain transport tank, making the grain quality less likely to be affected.

[0006] Preferably, the cooling pipe includes a cooling water inlet section and a cooling water outlet section; an extension section is provided at the end of the cooling water outlet section near the cooling water inlet section, the extension section extends into the cooling water inlet section, and a sealing ring is nested on the outside of the extension section, and the sealing ring is tightly pressed against the inner wall of the cooling water inlet section.

[0007] With this technical solution, when installing the cooling pipe, the cooling water inlet section and the cooling water outlet section are moved closer together, shortening the overall length of the cooling pipe. This allows the cooling pipe to be more easily moved between the water supply pipe and the drain pipe, making installation of the cooling pipe more convenient and quicker. A sealing ring seals the gap between the extension section and the cooling water inlet section, preventing seawater flowing through the cooling pipe from leaking out from between the extension section and the cooling water inlet section.

[0008] Preferably, the end of the cooling water inlet section is rotatably connected to a water inlet connecting section, the water inlet connecting section is threadedly connected to the inside of the water supply pipe, an O-ring 1 is nested on the outside of the water inlet connecting section, and the O-ring 1 is tightly pressed against the inner wall of the cooling water inlet section; the end of the cooling water outlet section is rotatably connected to a water outlet connecting section, the water outlet connecting section is threadedly connected to the inside of the drain pipe, an O-ring 2 is nested on the outside of the water outlet connecting section, and the O-ring 2 is tightly pressed against the inner wall of the cooling water outlet section.

[0009] Through the above technical solution, the water inlet connecting section is rotatably connected to the cooling water inlet section. This allows the cooling water inlet pipe to be connected to the water supply pipe by simply controlling the rotation of the water inlet connecting section. O-ring 1 seals the gap between the water inlet connecting section and the cooling water inlet section, thereby improving the sealing of the cooling pipe. The water outlet connecting section is rotatably connected to the cooling water outlet section. This allows the cooling water outlet pipe to be connected to the drain pipe by simply controlling the rotation of the water outlet connecting section. O-ring 2 seals the gap between the water outlet connecting section and the cooling water outlet section, thereby improving the sealing of the cooling pipe.

[0010] Preferably, a guide groove is provided on the inner wall of the cooling water inlet section along the axial direction, and a guide block is provided on the outer wall of the extension section, and the guide block is slidably connected to the guide groove.

[0011] Through the above technical solution, the guide groove and the guide block cooperate with each other to limit the relative rotation between the cooling water inlet section and the cooling water outlet section, so that the sealing ring arranged between the cooling water inlet section and the cooling water outlet section is not easily worn.

[0012] Preferably, the interior of the cooling water inlet section is fixedly connected with a fixed plate, and a water hole is provided axially through the fixed plate; the interior of the cooling water inlet section is rotatably connected with a rotating plate, and the rotating plate is located on the side of the fixed plate close to the cooling water outlet section, and the rotating plate is tightly attached to the fixed plate; a water hole is provided axially through the rotating plate, and the second water hole is connected with the first water hole, and a guide groove is provided at the end surface of the rotating plate away from the cooling water outlet section, one end of the guide groove is connected with the second water hole, and the other end of the guide groove is along the circumference of the rotating plate. The guide groove gradually decreases toward the side away from the second water hole; a limiting hole one is axially penetrated along the upper edge of the fixed plate, a limiting hole two is axially penetrated along the upper edge of the rotating plate, a limiting rod is provided at the end of the extension section away from the cooling water outlet section, a guiding slope is provided at the end of the limiting rod, and the guiding slope is used to guide the limiting rod to pass through the second water hole; when the limiting rod passes through the limiting hole one and the limiting hole two, the first water hole is offset from the second water hole, and the end of the guide groove away from the second water hole is communicated with the first water hole.

[0013] Through the above technical solution, when the cooling pipe is not yet fully extended, the limiting rod passes through limiting hole 1 and limiting hole 2. At this time, water hole 1 and water hole 2 are offset from each other, and the cooling pipe is in a blocked state. In other words, before the cooling pipe is fully installed, seawater cannot flow through the cooling pipe, and the seawater in the water inlet tank can increase rapidly. When the cooling water inlet section is fully connected to the water supply pipe and the cooling water outlet section is fully connected to the drain pipe, the limiting rod is pulled out from water hole 1 and water hole 2. At this time, the seawater in the cooling water inlet section exerts a force on the inner groove wall of the guide groove, thereby driving the rotating plate to rotate circumferentially until water hole 1 and water hole 2 are coaxially connected. In other words, the cooling pipe can be automatically opened when installation is complete, which is more convenient to use. When the cooling pipe is removed from between the water supply pipe and the drain pipe, the cooling water inlet section and the cooling water outlet section approach each other. At the same time, the limit rod continues to approach the second connecting hole. When the guiding slope conflicts with the inner wall of the second connecting hole, the limit rod can drive the rotating plate to rotate in the opposite direction, so that the second connecting hole is misaligned with the first connecting hole, so that the cooling pipe is in a disconnected state.

[0014] Preferably, a positioning groove is provided in the axial direction on the inner wall of the water supply pipe, a driving inclined surface is provided at the end of the positioning groove close to the water inlet chamber, and the driving inclined surface faces the water inlet connection section; the water supply valve comprises a movable valve body, a supporting spring and a movable valve core; the movable valve body is slidably connected to the water supply pipe, a sliding groove is provided in the radial direction on the side wall of the movable valve body, a receiving groove is provided at the bottom of the sliding groove, and a through hole is provided on the movable valve body along the axial direction. Water hole one; one end of the support spring one is fixedly connected to the receiving groove one, and the other end of the support spring one protrudes from the notch of the receiving groove one; the movable valve core one is slidingly connected to the sliding groove one, one end of the movable valve core one is fixedly connected to the support spring one, and the other end of the movable valve core one is provided with a positioning block one, and the positioning block one is slidingly connected to the positioning groove one, and a water hole two is axially penetrated on the movable valve core one, and the water hole two is used to communicate with the water hole one.

[0015] Through the above technical solution, when the water inlet connecting section is threadedly connected to the water supply pipe, the water inlet connecting section will push the movable valve body 1 to move toward the side of the water inlet tank. At the same time, the positioning block 1 moves toward the driving inclined surface 1 in the positioning groove 1. When the positioning block 1 touches the driving inclined surface 1, the driving inclined surface 1 will drive the movable valve core 1 to move toward the sliding groove 1 through the positioning block 1. When the water inlet connecting section is connected to the water supply pipe, the movable valve core 1 completely enters the sliding groove 1, and the water through hole 2 is coaxially connected to the water through hole. At this time, the seawater in the water inlet tank can enter the cooling pipe under the action of pressure.

[0016] Preferably, the inner wall of the drainage pipe is provided with a second positioning groove along the axial direction, and the end of the second positioning groove close to the water outlet compartment is provided with a second driving slope, and the second driving slope faces the side of the water outlet connection section; the water supply valve includes a second movable valve body, a second supporting spring and a second movable valve core; the second movable valve body is slidably connected to the drainage pipe, and a second sliding groove is provided on the side wall of the second movable valve body in the radial direction, and a second receiving groove is provided at the bottom of the second sliding groove, and a water-passing groove is provided on the second movable valve body in the axial direction. Hole three; one end of the support spring two is fixedly connected to the receiving groove two, and the other end of the support spring two protrudes from the notch of the receiving groove two; the movable valve core two is slidingly connected in the sliding groove two, and one end of the movable valve core two is fixedly connected to the support spring two, and the other end of the movable valve core two is provided with a positioning block two, and the positioning block two is slidingly connected in the positioning groove two, and a water hole four is axially penetrated on the movable valve core two, and the water hole four is used to communicate with the water hole three.

[0017] Through the above technical solution, when the water outlet connecting section is threadedly connected to the drain pipe, the water outlet connecting section will push the movable valve body 2 to move toward the side of the water outlet compartment. At the same time, the positioning block 2 moves toward the driving inclined plane 2 in the positioning groove 2. When the positioning block 2 touches the driving inclined plane 2, the driving inclined plane 2 will drive the movable valve core 2 to move toward the sliding groove 2 through the positioning block 2.
