Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a side outer plate cleaning device and a ship. Background Art

[0002] LNG (liquefied natural gas) powered ships use LNG as fuel. When LNG-powered ships dock to refuel, some LNG often leaks and flows along the deck to the ship's side deck and side plating, where it adheres to the ship's side. This leaked LNG poses a risk of ignition and explosion. During cleanup, crew members typically use high-pressure water jets to flush away LNG adhering to the side deck. However, flushing away LNG adhering to the side plating is difficult due to the inconvenience of the operation, and the crew must stand close to the ship's side, posing a risk of falling into the sea.

[0003] To address this issue, conventional techniques typically involve installing a water curtain cleaning device on the ship's side. The device's spray holes are positioned directly against the side plating to be cleaned, spraying water to flush the plating and, in turn, remove any liquefied natural gas (LNG) adhering to the plating. However, the fixed spray angle of the water holes results in a fixed flushing location on the side plating. While the portion of the plating below the flushing location can still be flushed by gravity as the flushing water flows downward, the portion above the flushing location becomes a blind spot and cannot be flushed.

[0004] Therefore, a side plate cleaning device and a ship are badly needed to solve the above problems. Utility Model Content

[0036] Figure 1 FIG. 1 shows a schematic diagram of the structure of the side plate cleaning device provided in this embodiment installed on a ship. Figure 1 As shown, when port fueling equipment injects liquefied natural gas into a ship's LNG filling station 300, some liquefied natural gas will leak and flow along the deck to the ship's side upper deck 100 and side shell 200, where it adheres to them. This leaked liquefied natural gas poses a risk of ignition and explosion. Crew members can typically stand on deck and use high-pressure water guns to flush away the liquefied natural gas adhering to the side upper deck 100. However, this operation is inconvenient and requires crew members to be close to the ship's side, posing a risk of falling into the sea. To address this issue, conventional water curtain cleaning devices are typically installed at the ship's side. While the water spray holes of the water curtain cleaning device can spray water to flush the side shell 200, the water spray holes have a fixed spray angle, resulting in a fixed flushing position on the side shell 200. The portion of the side shell 200 below the flushing position can still be flushed by gravity as the flushing water flows downstream, while the portion of the side shell 200 above the flushing position becomes a blind spot and cannot be flushed. Therefore, in order to solve the above problems, this embodiment provides a side plate cleaning device, which can flush the part of the ship's side plate 200 to be cleaned to avoid explosion caused by residual liquefied natural gas and ensure the personal and property safety of the ship and crew. Figures 1 to 4 The side outer plate cleaning device and the ship provided by the utility model are introduced in detail.

[0037] Figure 2FIG. 1 shows a schematic diagram of the structure of the side plate cleaning device provided in this embodiment installed in another direction of the ship. Figures 1 to 2 As shown, the side plate cleaning device provided in this embodiment includes a frame 1, a flushing assembly 2 and an adjusting member 3. The frame 1 is fixed to the side upper deck 100; the flushing assembly 2 includes a water curtain pipe 21 and a water supply member 22. The water curtain pipe 21 is pivotally connected to the frame 1, and the water curtain pipe 21 has a water spray hole 211. The two ends of the water supply member 22 are respectively connected to the water source and the inlet of the water curtain pipe 21, so that the water supply member 22 can supply water to the water curtain pipe 21 and make the water spray hole 211 spray out flushing water. When the flushing water sprayed from the water spray hole 211 starts to flush the side plate 200, a flushed area can be formed on the side plate 200; the adjusting member 3 is used to adjust the side plate 200. The entire component 3 is configured to adjust the relative angle between the water curtain tube 21 and the frame 1 so that the outlet of the water spray hole 211 is directly opposite the part to be cleaned of the side outer plate 200 of the ship. In the process of adjusting the relative angle between the water curtain tube 21 and the frame 1 by the adjusting component 3, the washed area of ​​the side outer plate 200 is continuously adjusted. Therefore, when there is a blind spot in cleaning of the side outer plate 200, the washed area of ​​the side outer plate 200 can be adjusted to wash the blind spot, thereby improving the cleaning effect of the side outer plate cleaning device.

[0038] Preferably, the flushing assembly 2 further includes an eye ring 23, which is fixed to the water curtain tube 21, and the adjusting member 3 can be hooked on the eye ring 23 to drive the water curtain tube 21 to rotate. Therefore, when there is a blind spot in the cleaning of the side shell 200, the crew can use the adjusting member 3 to pull the eye ring 23 to adjust the relative angle between the water curtain tube 21 and the frame 1 to adjust the flushing position of the side shell 200, so that the blind spot in the cleaning of the side shell 200 is flushed. The flushing position of the side shell 200 can be adjusted without using an electric device, thereby preventing the static electricity generated by the operation of the electric device from detonating the liquefied natural gas.

[0039] Furthermore, the adjusting member 3 includes a handle portion 31 and a hook portion 32 that are connected and arranged at an angle. The hook portion 32 can be hooked in the eye ring 23, thereby facilitating operation by the crew, enabling the crew to hold the handle portion 31 away from the side outer plate 200 and use the hook portion 32 to adjust the relative angle between the water curtain tube 21 and the frame 1 to adjust the flushing position of the side outer plate 200, thereby improving the safety of the side outer plate cleaning device.

[0040] In other embodiments, the adjustment member 3 may also be a motor connected to the flushing assembly 2 to adjust the relative angle between the water curtain tube 21 and the frame 1 to adjust the flushing position of the side shell 200. To prevent static electricity generated by the motor from detonating the liquefied natural gas, the motor may be grounded to discharge static electricity. All adjustment members 3 capable of adjusting the relative angle between the water curtain tube 21 and the frame 1 are within the scope of protection of this embodiment and are not described in detail here.

[0041] Due to the long-term use of flushing water sprayed from the spray holes 211 of the drencher tube 21 against the side plating 200, a large amount of scale and impurities can easily accumulate inside the drencher tube 21, causing the spray holes 211 to clog. To address this technical problem, a cleaning port is provided at one end of the drencher tube 21. This port is equipped with a plugging member 24. This plugging member 24 prevents the flushing water from leaking from the drencher tube 21 when the spray holes 211 of the drencher tube 21 are flushing the side plating 200. If scale and impurities accumulate inside the drencher tube 21 after prolonged use, the plugging member 24 can be removed, allowing the water supply member 22 to continue supplying water to the drencher tube 21, allowing the flushing water to flow out of the drencher tube 21, thereby flushing the interior of the drencher tube 21 and cleaning it to prevent clogging of the spray holes 211. In this example, the other end of the drencher tube 21 is connected to the water supply member 22.

[0042] In other embodiments, cleaning ports are provided at both ends of the water curtain tube 21, and the cleaning ports are provided with blocking members 24. When the blocking members 24 are removed and the water supply member 22 continues to supply water to the water curtain tube 21, flushing water can flow out from the nozzles on both sides of the water curtain tube 21, thereby further improving the ability to clean the interior of the water curtain tube 21. In this example, an inlet is opened on the side wall of the water curtain tube 21, and the inlet is connected to the water supply member 22. This arrangement can improve the uniformity of the flushing water sprayed from the multiple water spray holes 211 arranged along the axial direction of the water curtain tube 21.

[0043] Optionally, the blocking member 24 can be connected to the water curtain pipe 21 by means of threaded connection, plugging, etc. It is worth noting that the blocking member 24 can be any blocking member that can play a blocking role, such as a blind flange, a sealing sleeve, etc., as long as the blocking member 24 can be removed to clean the scale and impurities inside the water curtain pipe 21 when scale and impurities accumulate inside the water curtain pipe 21. The details will not be repeated here.

[0044] Figure 3 FIG. 2 shows a partial structural diagram of the water curtain tube 21 provided in this embodiment. Figure 3 As shown, a plurality of water spray holes 211 are arranged in an M×N array, with adjacent rows of water spray holes 211 staggered. This allows the flushing water ejected from the water spray holes 211 to form a flushing surface of a certain length and width on the side shell 200. This increases the area of ​​the side shell 200 directly flushed by the flushing water, thus expanding the area of ​​the side shell 200 flushed, thereby further improving the cleaning effect of the side shell cleaning device. M is an integer greater than or equal to 1, and N is an integer greater than or equal to 1.

[0045] Figure 4 Shown Figure 2 Schematic diagram of the local structure at A in the figure. Figures 1 to 2 and Figure 4As shown, the frame 1 has a storage groove 11, and the flushing assembly 2 also includes a pipe rack 25. The water curtain tube 21 is pivotally connected to the frame 1 through the pipe rack 25, and the pipe rack 25 can switch between a storage position in which it is accommodated in the storage groove 11 and a working position away from the storage groove 11. When the water curtain tube 21 is in the working position, the water spray hole 211 can face the side outer plate 200 and flush the side outer plate 200. When the water curtain tube 21 is in the storage position, the projection of the water curtain tube 21 is located in the side outer plate 200, and the water curtain tube 21 no longer flushes the side outer plate 200. The storage groove 11 accommodates the water curtain tube 21, thereby saving space on the side deck.

[0046] Furthermore, the frame 1 is provided with a locking member 12. When the water curtain pipe 21 is in the stowed position, the locking member 12 is used to lock the relative position between the pipe rack 25 and the frame 1, so that the water curtain pipe 21 remains in the stowed position, thereby saving space on the side upper deck. Specifically, the locking member 12 is a bolt. The frame 1 is provided with a threaded hole. The locking member 12 can pass through the pipe rack 25 and screw into the threaded hole, thereby securing the pipe rack 25 to the frame 1. The pipe rack 25 is rotatably connected to the frame 1 through the locking member 12.

[0047] In some embodiments, the frame 1 is slidably connected to the side upper deck 100. Thus, if liquefied natural gas leaks occur at any location on the side outer plate 200, the flushing assembly 2 can be adjusted to flush the side outer plate 200. Specifically, a slide rail is provided on the side upper deck 100, and the frame 1 has a slider that slidably engages with the slide rail.

[0048] Continue as Figures 1 to 2 and Figure 4 As shown, the water curtain tube 21 is detachably connected to the pipe rack 25. Therefore, when the water spray hole 211 of the water curtain tube 21 is blocked, the water curtain tube 21 can be quickly disassembled, and the blocking member 24 can be easily removed, thereby improving the maintenance efficiency of the water curtain tube 21. Specifically, the pipe rack 25 has a pipe clamp, and the water curtain tube 21 is clamped by the pipe clamp and detachably fixed to the pipe rack 25. Of course, all fixing methods that can make the water curtain tube 21 detachable and fixed to the pipe rack 25 are within the scope of protection of this embodiment and are not further described here.

[0049] Continue as Figure 1 、 Figure 2 and Figure 4As shown, the frame 1 is provided with a limiter 13, which can limit the maximum rotation angle of the water curtain tube 21 relative to the frame 1, so that when the water curtain tube 21 is in the working position, the water curtain tube 21 can remain stationary at the maximum rotation angle position relative to the frame 1. Therefore, when flushing the side outer plate 200, the crew can use the adjustment member 3 to adjust the relative angle between the water curtain tube 21 and the frame 1 to adjust the flushed position of the side outer plate 200 and flush the cleaning dead corner only when flushing the cleaning dead corner. When not flushing the cleaning dead corner, the crew can not operate the adjustment member 3, thereby reducing the work intensity of the crew in flushing the side outer plate 200. Specifically, the limiter 13 is a support plate that can support the water curtain tube 21, thereby limiting the maximum rotation angle of the water curtain tube 21 relative to the frame 1.

[0050] This embodiment also provides a ship, including a side upper deck 100, a side outer plate 200 and the above-mentioned side outer plate cleaning device, wherein the side outer plate 200 is erected on one side of the side upper deck 100, and the side outer plate cleaning device is arranged on the side upper deck 100 and is used to clean the side outer plate 200, thereby enabling the side outer plate 200 of the ship to be kept clean.

[0051] During the actual use of the ship, a large amount of liquid natural gas is dissolved in the flushing water after flushing the side upper deck 100. The flushing water used to flush the side upper deck 100 will slowly flow down along the outer wall of the side outer plate 200. Some of the liquid natural gas dissolved in the flushing water will still remain on the side outer plate 200, posing a safety hazard. In order to solve the above technical problems, the upper part of the side outer plate 200 protrudes from the top surface of the side upper deck 100, and a water accumulation space is enclosed between the side upper deck 100 and the side outer plate 200. A drainage hole connected to the water accumulation space is opened on the side outer plate 200, and the drainage hole is located within the cleaning range of the water curtain pipe 21, so that the flushing water after flushing the side upper deck 100 can be concentrated and discharged from the drainage hole. The water curtain pipe 21 can flush the drainage hole to prevent liquid natural gas from remaining in the drainage hole. Even if liquid natural gas remains at the side outer plate 200 corresponding to the drainage hole, the flushed area of ​​the side outer plate 200 can be adjusted by adjusting the relative angle between the water curtain pipe 21 and the frame 1, and it can be flushed, thereby further improving the cleaning ability of the side outer plate cleaning device and improving the safety performance of the ship.

[0052] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
