[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-5 As shown, this utility model discloses a low-pressure fire-fighting device for self-unloading ships, comprising:

[0029] Support assembly 1, the support assembly 1 includes a main deck surface 11 and a self-unloading arm 12, one end of the self-unloading arm 12 is disposed on the main deck surface 11, and a base 13 is disposed between the self-unloading arm 12 and the main deck surface 11;

[0030] Firefighting component 2 includes a seawater tank 21, a fire pump 22, a main water inlet pipe 23, a main sprinkler pipe 24, and multiple sprinkler risers 241. The seawater tank 21 is located at the bottom of the main deck surface 11. The main sprinkler pipe 24 is axially arranged on both sides of the self-unloading boom 12. The multiple sprinkler risers 241 are axially arranged along the main sprinkler pipe 24 and are close to the height direction of the self-unloading boom 12. The sprinkler risers 241 are connected to the main sprinkler pipe 24 and have at least two sets of nozzles 25 axially arranged. One end of the main water inlet pipe 23 is connected to the seawater tank 21, and the other end of the main water inlet pipe 23 passes through the base 13 and is connected to the main sprinkler pipe 24. The fire pump 22 is installed on the main water inlet pipe 23.

[0031] The control component 3 includes a control box 31, which is electrically connected to the fire pump 22.

[0032] The fire-fighting device of this invention is installed on a self-unloading vessel. A self-unloading boom 12 is mounted on the main deck 11 of the self-unloading vessel, and the self-unloading boom 12 can rotate at different angles via a base 13. The fire pump 22 in the fire-fighting assembly 2 provides power to pump water from the seawater tank 21 into the sprinkler main pipe 24, which then passes through sprinkler risers 241 and finally sprays water from nozzles 25. Specifically, the seawater tank 21 stores seawater and is positioned at the bottom of the main deck 11. The sprinkler main pipe 24 is axially positioned on both sides of the self-unloading boom 12. Multiple sprinkler risers 241 are equidistantly distributed axially along the sprinkler main pipe 24 and are positioned close to the height of the self-unloading boom 12. Each sprinkler riser 241 is equipped with at least two sets of nozzles 25, and each nozzle 25 is positioned directly facing the working area (conveyor belt) of the self-unloading boom 12. The spray area of ​​the multiple nozzles 25 covers the entire self-unloading boom 12. The electrical signal of the fire pump 22 is connected to the control box 31 to control the start and stop of the fire pump 22. When a fire occurs in the area of ​​the self-unloading boom 12, the fire pump 22 pumps the water in the seawater tank 21 to the sprinkler main pipe 24. After the seawater enters the sprinkler riser 251, it is sprayed into the area of ​​the self-unloading boom 12 through the nozzles 25, providing reliable fire protection for the self-unloading boom 12.

[0033] This utility model provides reliable fire protection for the self-unloading boom 12 by installing a main sprinkler pipe 24 and a sprinkler riser 241 on both sides of the self-unloading boom 12. When a fire occurs in the area of ​​the self-unloading boom 12, the fire pump 22 pumps water from the seawater tank 21 to the main sprinkler pipe 24 and the sprinkler riser 241, and sprays it into the area of ​​the self-unloading boom 12 through the nozzles 25.

[0034] Furthermore, a first throttle valve 231 is provided at one end of the water inlet main pipe 23 near the seawater tank 21. Specifically, the seawater tank 21 is used to store seawater, and the water flow from the seawater tank 21 to the water inlet main pipe 23 can be controlled by the first throttle valve 231.

[0035] Furthermore, the fire pump 22 is provided with a second throttle valve 232 at its inlet end and a third throttle valve 233 at its outlet end.

[0036] Specifically, a second throttle valve 232 and a third throttle valve 233 are installed on both sides of the fire pump 22. On the one hand, they can be used to adjust the flow rate of the fire pump 22, control the pressure of the entire pipeline, and protect the pump; on the other hand, they can facilitate subsequent inspection and maintenance.

[0037] Furthermore, a filter 29 is provided between the second throttle valve 232 and the fire pump 22.

[0038] Specifically, filter 29 is installed at the inlet of fire pump 22 to filter seawater inside seawater tank 21, preventing impurities from entering fire pump 22 and damaging its impeller; it also effectively prevents nozzle 25 from becoming clogged. As a preferred embodiment of this invention, the second throttle valve 232 facilitates the cleaning and maintenance of filter 29.

[0039] Furthermore, a check valve 234 is provided between the third throttle valve 233 and the fire pump 22. The check valve 234 prevents water from flowing back into the fire pump 22.

[0040] Furthermore, pressure sensors 32 are also provided at both ends of the fire pump 22, and the pressure sensors 32 are electrically connected to the control box 31.

[0041] Specifically, pressure sensors 32 are arranged before and after the fire pump 22 to monitor the status of the fire pump 22, prevent abnormal pressure of the fire pump 22, and ensure the normal operation of the fire pump 22. Preferably, the pressure sensors 32 are connected to the control box 31, and the pressure sensors 32 feed back the detected signals to the control box 31.

[0042] Furthermore, a universal joint 26 is provided between the water inlet main pipe 23 and the spray main pipe 24. A corrugated expansion joint 27 and a hose 28 are respectively provided on both sides of the universal joint 26. The corrugated expansion joint 27 is connected to the water inlet main pipe 23, and the hose 28 is connected to the spray main pipe 24.

[0043] Specifically, the corrugated expansion joint 27 can absorb the expansion and contraction of the vertical distance between the unloading boom 12 body and the steel pipe, preventing crushing and breakage. The universal joint 26 connected above the corrugated expansion joint 27 can rotate in the axial direction to counteract the effects of the unloading boom 12's rotation. If the universal joint 26 is not at the rotation center of the unloading boom 12, the unloading boom 12 may twist during rotation, causing the universal joint 26 to malfunction. The flexible hose 28 connects the steel pipe on the unloading boom 12 and the steel pipe at the base of the unloading boom 12, and has a certain degree of elasticity. This facilitates connection and effectively reduces the impact of the unloading boom 12's rotation on the universal joint 26.

[0044] Furthermore, an electromagnetic throttle valve 235 is installed on the pipeline of the main spray pipe 24 near the end of the main water inlet pipe 23, and the electromagnetic throttle valve 235 is electrically connected to the control box 31.

[0045] Specifically, the sprinkler main pipe 24 on the self-unloading boom 12 is divided into left and right branches, each with an electromagnetic throttle valve 235 as the main control valve to control each branch. Each sprinkler main pipe 24 is equipped with several nozzles 25 for fire coverage of the self-unloading boom 12. Similarly, the electromagnetic throttle valve 235 is communicatively connected to the control box 31, and the operating status of the electromagnetic throttle valve 235 is controlled by the control box 31.

[0046] Furthermore, a first ball valve 236 is also provided on the pipeline of the main spray pipe 24, and a quick connector 237 is provided on the first ball valve 236.

[0047] Specifically, each spray pipe 24 is equipped with a first ball valve 236 for backflushing inside the spray pipe 24. By connecting the quick connector 237 on the first ball valve 236 to compressed air, the inside of the spray pipe 24 is periodically purged to prevent blockage of the pipe and nozzle 25.

[0048] Furthermore, a second ball valve 238 is provided on the pipeline of the main water inlet 23 near the base 13, and a fire hose connector 239 is provided on the second ball valve 238.

[0049] Specifically, by installing the second ball valve 238, the ship's fire-fighting system can be integrated into the main water inlet pipe 23 to prevent the seawater tank 21 from running out of water or other emergencies. As a preferred embodiment of this utility model, the second ball valve 238 is equipped with a fire hose connector 239 for convenient and quick connection to fire-fighting pipelines.

[0050] In summary, this utility model introduces a low-pressure fire-fighting device for a self-unloading vessel. By installing a main sprinkler pipe 24 and a sprinkler riser 241 on both sides of the self-unloading wall to cover the working area of ​​the self-unloading arm 12, when a fire occurs in the area of ​​the self-unloading arm 12, the fire pump 22 pumps water from the seawater tank 21 to the main sprinkler pipe 24 and the sprinkler riser 241, and sprays it into the area of ​​the self-unloading arm 12 through the nozzles 25, providing reliable fire protection for the self-unloading arm 12.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
