Description

Technical Field

[0001] The present invention relates to the technical field of water-cooled refrigerated container ships, and particularly relates to an anti-collision structure and method for the cooling water hoses of ship containers. Background Art

[0002] As Figure 3 shown, the cooling water inlet and outlet of the container 4 on a water-cooled refrigerated container ship are connected to the cooling water supply pipe and the cooling water return pipe of the ship cooling water pipeline system 1 through the inlet hose 7 and the return hose 8. When the container 4 is an ordinary container and does not require cooling, the inlet hose 7 and the return hose 8 connected to the ship cooling water pipeline system are in a natural drooping state and cannot be completely fixed. During the ship's navigation, the hoses 7 and 8 will sway with the ship, affecting the passage of personnel and also causing damage to the hoses due to collision with surrounding structures. Summary of the Invention

[0003] To solve the above problems, the present invention proposes an anti-collision structure and method for the cooling water hoses of ship containers, aiming to avoid or reduce damage to the cooling water hoses and ensure the safety and reliability of the use of the cooling water hoses of ship containers. The specific technical solutions are as follows:

[0004] An anti-collision structure for the cooling water hoses of ship containers includes a ship cooling water pipeline system, a hose assembly connecting the ship cooling water pipeline system, and a U-shaped pipe fixed to the hull. The ship cooling water pipeline system includes a cooling water supply pipeline and a cooling water return pipeline for container cooling. The hose assembly includes an inlet hose and a return hose. One end of the inlet hose is connected to the cooling water supply pipeline, and one end of the return hose is connected to the cooling water return pipeline. Pipe joints adapted to be connected to the inlet hose and the return hose are respectively provided at the two ends of the U-shaped pipe.

[0005] When the ship container is a water-cooled container, the other end of the inlet hose is directly connected to the container cooling water inlet on the water-cooled container, and the other end of the return hose is directly connected to the container cooling water outlet on the water-cooled container; wherein, pipe joints adapted to be connected to the inlet hose and the return hose are respectively provided at the container cooling water inlet and the container cooling water outlet.

[0006] When the ship container is an ordinary container that does not require cooling, the other end of the inlet hose and the other end of the return hose are respectively connected to the pipe joints at the two ends of the U-shaped pipe.

[0007] In the present invention, the U-shaped pipe is fixed to the hull near the container through a bracket.

[0008] In the present invention, branch pipes are respectively arranged on the cooling water supply pipeline and the cooling water return pipeline. Pipe joints are arranged on the branch pipes, and the inlet hose and the return hose are respectively connected to the pipe joints of the branch pipes.

[0009] Preferably, a stop valve is arranged on the branch pipe.

[0010] As a further improvement of the present invention, a hose anti-damage detection device is also connected to the branch pipe. The hose anti-damage detection device includes a vacuum box arranged on the periphery of the branch pipe, and a sleeve that is sleeved on the periphery of the branch pipe and communicated with the inside of the vacuum box. A flexible detection pipe is sleeved on the outer circles of the inlet hose and the return hose. One end of the flexible detection pipe is sleeved on the outer circle of the sleeve and forms a sealed connection with the outer circle of the sleeve. The other end of the flexible detection pipe is correspondingly and sealingly connected to the outer circle of the other end of the inlet hose or the outer circle of the other end of the return hose. A vacuum sensor and a vacuum extraction connection pipe are respectively arranged on the vacuum box, and a stop valve is arranged on the vacuum extraction connection pipe.

[0011] Preferably, the vacuum sensor is connected to an alarm control system.

[0012] Preferably, the alarm control system is an MCU alarm control system.

[0013] During installation, connect the vacuum extraction connection pipe to a vacuum extraction device, open the stop valve on the vacuum extraction connection pipe, start the vacuum extraction device, evacuate the air in the vacuum box, so that the air pressure in the vacuum box becomes negative pressure, and then close the stop valve on the vacuum extraction connection pipe and remove the vacuum extraction device. After vacuum extraction, the gap between the inside of the flexible detection pipe and the hose also becomes negative pressure. When the hose (inlet hose or return hose) undergoes an accidental strong collision, the first damaged part is the flexible detection pipe sleeved on the hose, resulting in the destruction of the negative pressure in the gap between the inside of the flexible detection pipe and the hose. The air pressure in the connected vacuum box rises, and the rise in air pressure can be detected by the vacuum sensor in time, so that the alarm control system issues an alarm to remind relevant personnel to conduct an inspection. In the case where the flexible detection pipe is damaged but the hose is not damaged, the flexible detection pipe can be reinstalled, so that the hose can always be in a monitored state, thereby ensuring the safety of the hose assembly in the ship cooling water pipeline system.

[0014] Preferably, the sealed connection between the flexible detection pipe and the other end of the inlet hose or the other end of the return hose is a glued connection.

[0015] In order to improve the sensitivity and reliability of detection, external threads are arranged on the outer circles of the inlet hose and the return hose.

[0016] Since external threads are provided on the outer circumferences of the water inlet hose and the water return hose, even if the flexible detection tube is completely attached to the hose under the action of negative pressure, the outside air entering through the local breakage on the hose can quickly enter the vacuum box through the thread grooves of the external threads, and thus can be timely monitored by the vacuum sensor.

[0017] In the present invention, a section of external thread is respectively provided at the outer circumferential root of the pipe joint and the outer circumferential root of the socket. After the water inlet hose and the water return hose are respectively sleeved on the outer circumference of the pipe joint, locking and sealing are achieved by connecting a locking nut on the external thread of the pipe joint; after the flexible detection tube is sleeved on the outer circumference of the socket, locking and sealing are achieved by connecting a locking nut on the external thread of the socket.

[0018] An anti-collision method for an anti-collision structure of a cooling water hose of a ship container is as follows:

[0019] When the ship container is a water-cooled container, the other end of the water inlet hose is directly connected to the container cooling water inlet on the water-cooled container, and the other end of the water return hose is directly connected to the container cooling water outlet on the water-cooled container; when the ship container is a general container that does not need to be cooled, the other ends of the water inlet hose and the water return hose are respectively connected to the pipe joints on the two ends of the U-shaped pipe.

[0020] When the flexible detection tube sleeved on the outer circumference of the water inlet hose or the water return hose is damaged due to collision, outside air enters the inside of the flexible detection tube from the damaged part of the flexible detection tube, and enters the vacuum box along the internal void of the flexible detection tube, or enters the vacuum box along the external thread groove on the water inlet hose or the water return hose. When the alarm control system finds that the air pressure in the vacuum box increases through the vacuum sensor, the alarm control system issues an alarm to remind the ship maintenance personnel to perform maintenance treatment in time, so as to achieve the purpose of protecting the water inlet hose or the water return hose.

[0021] The beneficial effects of the present invention are as follows:

[0022] First, for an anti-collision structure and an anti-collision method of a cooling water hose of a ship container according to the present invention, a U-shaped pipe is provided in the hose assembly. When the shipped container is a general container, the water inlet hose and the water return hose can be connected to the U-shaped pipe, so that the circulation of the cooling water system can be ensured, and the hose can be effectively fixed, thus playing an effective anti-collision role.

[0023] Second, for an anti-collision structure and an anti-collision method of a cooling water hose of a ship container according to the present invention, a hose anti-damage detection device is provided, so that the hose can always be in a monitored state, thereby ensuring the safety of the hose assembly in the ship cooling water pipeline system.

[0028] The following combines the accompanying drawings and embodiments to further describe the specific embodiments of the present invention. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figures 1 to 3 shown is an embodiment of an anti-collision structure for the cooling water hose of a ship container according to the present invention, including a ship cooling water pipeline system 1, a hose assembly 2 connecting the ship cooling water pipeline system 1, and a U-shaped pipe 3 fixed on the hull. The ship cooling water pipeline system 1 includes a cooling water supply pipeline 5 and a cooling water return pipeline 6 for cooling the container 4. The hose assembly 2 includes an inlet hose 7 and a return hose 8. One end of the inlet hose 7 is connected to the cooling water supply pipeline 5, and one end of the return hose 8 is connected to the cooling water return pipeline 6. Pipe joints 9 for adaptively connecting with the inlet hose 7 and the return hose 8 are respectively provided at both ends of the U-shaped pipe 3.

[0031] When the ship container 4 is a water-cooled container, the other end of the inlet hose 7 is directly connected to the container cooling water inlet on the water-cooled container 4, and the other end of the return hose 8 is directly connected to the container cooling water outlet on the water-cooled container 4; wherein, pipe joints 9 for connecting with the inlet hose 7 and the return hose 8 are respectively provided at the container cooling water inlet and the container cooling water outlet.

[0032] When the ship container 4 is an ordinary container 4 that does not need to be cooled, the other ends of the water inlet hose 7 and the water return hose 8 are respectively connected to the pipe connectors 9 on the two ends of the U-shaped pipe 3 correspondingly.

[0033] In this embodiment, the U-shaped pipe 3 is fixed to the hull near the container 4 through a bracket 10.

[0034] In this embodiment, branch pipes 11 are respectively arranged on the cooling water supply pipeline 5 and the cooling water return pipeline 6. Pipe connectors 9 are arranged on the branch pipes 11, and the water inlet hose 7 and the water return hose 8 are respectively connected to the pipe connectors 9 on the branch pipes 11 correspondingly.

[0035] Preferably, a stop valve 18 is arranged on the branch pipe 11.

[0036] As a further improvement of this embodiment, a hose anti-damage detection device 12 is also connected to the branch pipe 11. The hose anti-damage detection device 12 includes a vacuum box 13 arranged on the periphery of the branch pipe 11 and a sleeve 14 sleeved on the periphery of the branch pipe 11 and communicating with the inside of the vacuum box 13. A flexible detection pipe 15 is sleeved on the outer circles of the water inlet hose 7 and the water return hose 8. One end of the flexible detection pipe 15 is sleeved on the outer circle of the sleeve 14 and forms a sealed connection with the outer circle of the sleeve 14. The other end of the flexible detection pipe 15 is correspondingly sealed and connected to the outer circle of the other end of the water inlet hose 7 or the outer circle of the other end of the water return hose 8. A vacuum sensor 16 and a vacuum extraction connection pipe 17 are respectively arranged on the vacuum box 13, and a stop valve 18 is arranged on the vacuum extraction connection pipe 17.

[0037] Preferably, the vacuum sensor 16 is connected to an alarm control system.

[0038] Preferably, the alarm control system is an MCU alarm control system.

[0039] During installation, connect the vacuum extraction pipe 17 to a vacuum extraction device. Open the stop valve 18 on the vacuum extraction pipe 17, start the vacuum extraction device, and evacuate the air in the vacuum box 13 so that the air pressure in the vacuum box 13 becomes negative pressure. Then close the stop valve 18 on the vacuum extraction pipe 17 and remove the vacuum extraction device. After vacuum extraction, the space between the inside of the flexible detection pipe 15 and the hoses 7 and 8 also becomes negative pressure. When an accidental strong collision occurs to the hose (the water inlet hose 7 or the water return hose 8), the first part to be damaged is the flexible detection pipe 15 sleeved on the hose 7 or 8, resulting in the destruction of the negative pressure in the space between the inside of the flexible detection pipe 15 and the hose 7 or 8. The air pressure in the connected vacuum box 13 rises, and the rise in air pressure can be detected in time by the vacuum sensor 16, so that the alarm control system issues an alarm to remind relevant personnel to conduct an inspection. In the case where the flexible detection pipe 15 is damaged but the hoses 7 and 8 are not damaged, the flexible detection pipe 15 can be reinstalled after replacement, so that the hoses 7 and 8 can always be in a monitored state, thereby ensuring the safety of the hose assembly 2 in the ship cooling water pipeline system 1.

[0040] Preferably, the sealed connection between the flexible detection pipe 15 and the other end of the water inlet hose 7 or the other end of the water return hose 8 is a glued connection.

[0041] In order to improve the sensitivity and reliability of detection, external threads are provided on the outer circumferences of the water inlet hose 7 and the water return hose 8.

[0042] Since external threads are provided on the outer circumferences of the water inlet hose 7 and the water return hose 8, even if the flexible detection pipe 15 is completely attached to the hose 7 or 8 under the action of negative pressure, the outside air entering due to local damage on the hose 7 or 8 can quickly enter the vacuum box 13 through the thread grooves of the external threads and thus be detected in time by the vacuum sensor 16.

[0043] In this embodiment, a section of external thread is respectively provided at the outer circumferential root of the pipe joint 9 and the outer circumferential root of the socket 14. After the water inlet hose 7 and the water return hose 8 are respectively sleeved on the outer circumference of the pipe joint 9, locking and sealing are achieved by connecting the locking nut 19 on the external thread of the pipe joint 9; after the flexible detection pipe 15 is sleeved on the outer circumference of the socket 14, locking and sealing are achieved by connecting the locking nut 19 on the external thread of the socket 14.

[0044] Embodiment 2:

[0045] An anti-collision method for a ship container cooling water hose anti-collision structure adopting Embodiment 1 is as follows:

[0046] When the ship container 4 is a water-cooled container, the other end of the water inlet hose 7 is directly connected to the container cooling water inlet on the water-cooled container 4, and the other end of the return water hose 8 is directly connected to the container cooling water outlet on the water-cooled container 4; when the ship container 4 is a general container that does not need to be cooled, the other end of the water inlet hose 7 and the other end of the return water hose 8 are respectively connected to the pipe joints 9 on the two ends of the U-shaped pipe 3.

[0047] When the flexible detection tube 15 sleeved on the outer circle of the water inlet hose 7 or the return water hose 8 is damaged due to collision, external air enters the inside of the flexible detection tube 15 from the damaged part of the flexible detection tube 15, and enters the vacuum box 13 along the internal void of the flexible detection tube 15, or enters the vacuum box 13 along the external thread groove on the water inlet hose 7 or the return water hose 8. When the alarm control system finds that the air pressure in the vacuum box 13 increases through the vacuum sensor 16, the alarm control system issues an alarm to remind the ship maintenance personnel to perform maintenance in time, so as to achieve the purpose of protecting the water inlet hose 7 or the return water hose 8.

[0048] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
