Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a cabin ventilation device and a ship. Background Art

[0002] There are many tanks on a ship, such as empty tanks, ballast tanks, and oil tanks. These tanks are loaded with different media. The oil tank is for oil, the ballast tank is for water, and the empty tank is for no media. The oil tank provides fuel support for the ship's navigation, and the ballast tank is for adjusting the ship's buoyancy and stability.

[0003] In order to ensure that the cabin is connected to the atmosphere, a vent pipe is generally used to connect the cabin to the atmosphere outside the ship. The lower end of the vent pipe is installed on the freeboard deck on the top of the cabin and connected to the cabin, and the upper end of the vent pipe extends upward to the open area above the open deck to achieve ventilation. The vent pipe is determined according to the injection and discharge pressure of the cabin. When designing, it is necessary to ensure that the oil pump or water pump can achieve pressure balance during injection and discharge, so as to avoid the cabin pressure rising or falling during injection and discharge, and the gas cannot be discharged in time, causing deformation of the cabin.

[0004] At present, for cargo oil tankers, bulk carriers, etc., the ship's superstructure is relatively low, and the length of the vent pipe when arranged on the open deck is relatively short. However, for ro-ro passenger ships, PCTC ro-ro ships, etc., the entire ship's superstructure has more than ten floors, and the superstructure is very high. The path of the vent pipe extending upward to the top of the open deck is very long, and a very long vent pipe needs to be laid, making the installation and laying of the vent pipe very cumbersome and high in installation cost. Summary of the invention

[0047] In addition, it should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0048] Unless specifically stated or defined otherwise, the term "and / or" used in the present invention includes any and all combinations of one or more of the associated listed items.

[0049] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent.

[0050] like Figures 1 to 3 As shown, a cabin ventilation device is installed on a ship. The cabin ventilation device can be used for ventilation of the cabin 202 and also for facilitating the deployment of the anchor chain 21. The existing chain pipe 13 is generally limited to the deployment of the anchor chain 21 and does not have a ventilation function.

[0051] The cabin ventilation device includes a ventilation pipe 11, a first connecting pipe 12, and a chain pipe 13; the chain pipe 13 is vertically installed on the ship to facilitate the placement of the anchor chain 21. The chain pipe 13 is a passage hole for the anchor chain 21 to pass through. The anchor winch places the anchor chain 21 on the seabed and anchors the riverbed through the anchor device at the end of the anchor chain 21 to achieve mooring and fixation.

[0052] The vent pipe 11 has a first end 111 for communicating with the cabin 202 and a second end 112 communicating with the first connecting pipe 12. The first end 111 of the vent pipe 11 extends downward and is installed on the freeboard deck 201 on the top of the cabin 202 and communicates with the cabin 202, the second end 112 of the vent pipe 11 extends upward and communicates with the first connecting pipe 12, the first connecting pipe 12 extends transversely to communicate with the chain pipe 13, and the space of the cabin 202 is communicated with the chain pipe 13 through the vent pipe 11 and the first connecting pipe 12.

[0053] The freeboard deck is the first full-length deck adjacent to the water surface. The superstructure of the ship also includes multiple decks distributed above the freeboard deck 201, and generally one or more superstructure decks are distributed. For ships such as ro-ro passenger ships and PCTC ro-ro ships, there are sometimes more than ten superstructure decks distributed above the freeboard deck 201.

[0054] The chain pipe 13 has a conveying channel 131 for passing the anchor chain 21, and the conveying channel 131 vertically penetrates the chain pipe 13 from top to bottom. The conveying channel 131 has a channel opening 132 for communicating with the outside of the hull 20, and the channel opening 132 is located at the upper end of the conveying channel 131. The first connecting pipe 12 is connected to the conveying channel 131.

[0055] Thus, in this embodiment, when the vent pipe 11 is laid, in order to prevent the vent pipe 11 from extending upward to the open deck 201 at the top, the vent pipe 11 can be designed to be combined with the chain pipe 13, and both the vent pipe 11 and the chain pipe 13 are connected to the space outside the hull 20 through the channel opening 132 of the chain pipe 13, which not only solves the pressure balance problem in the cabin 202, but also prevents the chain pipe 13 from being deformed due to excessive pressure in the chain pipe 13 caused by the rolling waves rushing into the chain pipe 13. The length of the vent pipe 11 does not need to extend from the cabin 202 to the open deck 201 at the top of the hull 20, but only needs to extend upward and protrude above the freeboard deck 201, and then connect to the chain pipe 13 through the first connecting pipe 12, and connect to the outside of the hull 20 through the chain pipe 13 to achieve ventilation, so that the length of the vent pipe 11 is greatly shortened, reducing the difficulty and cost of ship manufacturing.

[0056] In some embodiments, the cabin ventilation device further includes a first liquid supply pipe 14 and a first nozzle 15. The upper end of the first liquid supply pipe 14 is used to connect the fire water, and the lower end of the first liquid supply pipe 14 is connected to the first nozzle 15. The first nozzle 15 is installed in the first connecting pipe 12 and the nozzle of the first nozzle 15 faces the conveying channel 131. When the anchor chain 21 is rolled up from the seabed, the anchor chain 21 will carry mud, seabed plants and other debris. The first nozzle 15 sprays liquid to clean the anchor chain 21, avoiding affecting the winding of the anchor and increasing the weight of the ship's route. In this way, in this embodiment, the first nozzle 15 can be built into the first connecting pipe 12, which can achieve both ventilation and cleaning of the anchor chain 21.

[0057] Optionally, the first connecting pipe 12 has a first pipe section 121. One end of the first pipe section 121 is connected to the chain pipe 13, and the other end of the first pipe section 121 extends upwardly in a direction away from the chain pipe 13. The first nozzle 15 is downwardly arranged in the pipe hole of the first pipe section 121 to ensure that the water flow does not flow back during the flushing process.

[0058] It can be understood that the first connecting pipe 12 also has a second pipe section, which extends horizontally. One end of the second pipe section is connected to the air vent pipe 11, and the other end of the second pipe section is connected to the left end of the first pipe section 121. The right end of the first pipe section 121 extends downward and is connected to the chain pipe 13.

[0059] Specifically, the second pipe section is arranged horizontally, which can reduce the overall length of the first connecting pipe 12 and facilitate the connection of one end of the second pipe section with the side of the vent head 17. At the same time, the gas flows horizontally when passing through the second pipe section, reducing resistance, facilitating the gas to enter and exit the vent pipe, and also reducing the impact of the airflow on the first nozzle 15.

[0060] In some embodiments, the first nozzle 15 is close to the connection point between the first connecting pipe 12 and the conveying channel 131. The first nozzle 15 is as close to the conveying channel 131 as possible, which can not only avoid affecting the winding and lowering of the anchor chain 21, but also improve the cleaning quality and further prevent the water from flowing back.

[0061] Optionally, the upper end of the first liquid supply pipe 14 is located outside the first connecting pipe 12 and is provided with a valve body 16, the valve body 16 controls the delivery of fire water, and the upper end of the first liquid supply pipe 14 is externally connected to the fire water. The lower end of the first liquid supply pipe 14 extends into the first connecting pipe 12 and is connected to the first nozzle 15. The outer side of the first connecting pipe 12 is provided with a pipe connection port 122, which is connected to the pipe hole of the first connecting pipe 12. The first liquid supply pipe 14 extends from the outer side of the first connecting pipe 12 through the pipe connection port 122 into the pipe hole of the first connecting pipe 12, and the outer side of the first liquid supply pipe 14 is welded to the edge of the pipe connection port 122.

[0062] In some embodiments, the first liquid supply pipe 14 is connected to the high-pressure fire-fighting system on the ship. Compared with the method in which the first liquid supply pipe 14 is connected to the domestic normal-pressure water system, this embodiment can use the first nozzle 15 to spray high-pressure water to flush the anchor chain 21, thereby efficiently flushing away the difficult-to-clean debris entangled on the anchor chain 21.

[0063] The inventor found that the first nozzle 15 sprays high-pressure water to flush the anchor chain 21, which can improve the cleaning effect of the anchor chain 21, but some debris washed down may be easily impacted quickly on the wall of the chain pipe 13 and then backwashed into the first connecting pipe 12. If debris is accumulated in the first connecting pipe 12 for a long time, the ventilation efficiency between the vent pipe 11 and the chain pipe 13 will be reduced, affecting the ventilation effect of the cabin 202 and causing safety hazards. Based on this, the present embodiment also adopts a method of tilting the first pipe section 121 of the first connecting pipe 12. Compared with the method of horizontally arranging the first pipe section 121, this method has some advantages: on the one hand, the high-pressure water sprayed by the first nozzle 15 can flush the anchor chain 21 downward at a certain tilt angle, and the flushing and cleaning effect is better; on the other hand, the debris flushed down by the high-pressure water can easily be discharged from the ship downward along the vertical chain pipe 13. Since the position where the high-pressure water impacts the anchor chain 21 is located below the connecting port between the first connecting pipe 12 and the chain pipe 13, the debris flushed down by the high pressure will not backwash into the first connecting pipe 12.

[0064] In some embodiments, the cabin ventilation device further includes a ventilation head 17. The ventilation pipe 11 is connected to the first connecting pipe 12 through the ventilation head 17. The ventilation head 17 can further prevent water from entering the ventilation pipe 11 and flowing back to the cabin 202.

[0065] In some embodiments, there are multiple ventilation pipes 11, first connecting pipes 12, first liquid supply pipes 14 and first nozzles 15, respectively. Multiple ventilation pipes 11 correspond to multiple first connecting pipes 12 one by one, so as to provide ventilation efficiency. Multiple first liquid supply pipes 14 correspond to multiple first nozzles 15 one by one, and at least some of the first connecting pipes 12 are installed with first nozzles 15 to improve the cleaning effect. Multiple first connecting pipes 12 are arranged at intervals along the circumference of the chain pipe 13. When manufacturing a ship, increasing the number of first connecting pipes 12 can improve the ventilation efficiency of the cabin 202 while improving the cleaning efficiency of the anchor chain 21, and the manufacturing cost is controlled.

[0066] Optionally, it also includes a second connecting pipe, a second liquid supply pipe and a second nozzle. One end of the second connecting pipe is sealed and does not need to be connected to the vent pipe 11, and the other end of the second connecting pipe is connected to the chain pipe 13. The second liquid supply pipe passes into the second connecting pipe and is connected to the second nozzle to achieve cleaning of the anchor chain 21.

[0067] In some embodiments, the cabin ventilation device further comprises an anchor winch for winding or releasing the anchor chain 21; the anchor winch has a storage chamber for storing the anchor chain 21. The anchor winch is installed above the chain tube 13. The anchor winch is not shown in the figure, and the anchor winch is located above the chain tube.

[0068] Specifically, the anchor winch includes a motor, a box body with a storage cavity, and a reel rotatably installed in the storage cavity. The reel is connected to the motor in a transmission manner, and the reel is connected to the upper end of the anchor chain 21 for winding and releasing the anchor chain 21.

[0069] The cabin ventilation device also includes a washer 19 for cleaning the anchor chain 21; the washer 19 is installed in the conveying channel 131. The washer 19 can clean the mud or plants such as seaweed on the anchor chain 21.

[0070] like Figure 4 and Fig.10 As shown, optionally, the cleaner 19 includes a brush sheet 191 installed on the inner wall of the conveying channel 131. The conveying channel 131 is a circular hole, and the bristles of the brush sheet 191 are arranged in sequence from top to bottom. There are multiple brush sheets 191 and they are arranged at intervals along the circumference of the conveying channel 131. When the anchor chain 21 is wound, the anchor chain 21 passes through the brush sheet 191 and generates friction with the brush sheet 191, so that the sludge and other attachments on the anchor chain 21 fall off.

[0071] In some embodiments, the cabin ventilation device further includes an adjuster 18 for arranging and adjusting the state of the anchor chain 21. The conventional anchor chain 21 generally consists of a plurality of sequentially connected links 211, and the links 211 are waist-shaped rings. When the anchor chain 21 is dropped into the sea, the plurality of sequentially connected links 211 are arranged sequentially from top to bottom under the action of gravity. Under normal conditions, the planes where two adjacent links 211 are located are vertically arranged and arranged at 90° or approximately 90° to each other. The maximum length direction of the links 211 is arranged from top to bottom, and the total length of the anchor chain 21 is the largest. However, due to the influence of plants such as sludge or seaweed, for example, some sludge that is difficult to wash away is stuck in the links 211 or seaweed is tied up in the links 211, which will cause the positions of adjacent links 211 to be disordered, and the upper and lower ends of the links 211 are not on the same vertical line. At this time, the anchor chain 21 is in an abnormal state, which is not conducive to the windlass winding the anchor chain 21, and the total length of the anchor chain 21 will also be shortened, affecting the next use. In addition, if the links 211 are kept in a disordered position for too long, the adjacent links 211 will be permanently fixed in position due to rust, and the length of the anchor chain 21 will be permanently shortened, affecting normal use. Therefore, the cabin ventilation device is provided with an adjuster 18 to adjust the position of the links 211, so that the anchor winch can wind up the anchor chain 21 while preventing the total length of the anchor chain 21 from being shortened.

[0072] Optionally, a first positioning ring 133 having a first annular hole 135 and a second positioning ring 134 having a second annular hole 136 are provided on the inner wall of the delivery channel 131. The first positioning ring 133 and the second positioning ring 134 are arranged at intervals from top to bottom, and the first positioning ring 133 and the second positioning ring 134 divide the delivery channel 131 into a first channel 1311, a second channel 1312, and a third channel 1313. The first channel 1311, the second channel 1312, and the third channel 1313 are arranged in sequence from top to bottom, and the first channel 1311 and the second channel 1312 are connected through the first annular hole 135, and the second channel 1312 and the third channel 1313 are connected through the second annular hole 136. The first connecting pipe 12 and / or the second connecting pipe are connected to the first channel 1311. A spiral groove 137 is provided on the inner wall of the second hole 1312 , and the spiral groove 137 spirally extends from top to bottom. The brush piece 191 is provided on the inner wall of the third hole 1313 .

[0073] The adjuster 18 includes an adjusting seat 181, a slide 182 disposed on the adjusting seat, a first spring 186, and a second spring 187. The slide 182 is slidably mounted in the spiral slide 137, so that the adjusting seat 181 is rotated and slidably mounted in the second channel 1312, and the first positioning ring 133 and the second positioning ring 134 are located on the up and down movement path of the adjusting seat 181, thereby limiting the up and down movement range of the adjusting seat 181. The first spring 186 is clamped between the first positioning ring 133 and the adjusting seat 181, and the second spring 187 is clamped between the second positioning ring 134 and the adjusting seat 181, so that the adjusting seat 181 is suspended between the first positioning ring 133 and the second positioning ring 134. When the adjusting seat 181 moves up and down, the first spring 186 and the second spring 187 can be compressed or stretched.

[0074] The adjustment seat 181 is provided with a first chain slot 1813 and a second chain slot 1814. The first chain slot 1813 and the second chain slot 1814 both penetrate the adjustment seat 181 from top to bottom. The first chain slot 1813 and the second chain slot 1814 are respectively used for adjacent links 211 to pass through, so the first chain slot 1813 and the second chain slot 1814 are cross-distributed along the projection of the vertical direction, and preferably, the first chain slot 1813 and the second chain slot 1814 are distributed at 90 degrees. The size and profile of the first chain slot 1813 and the second chain slot 1814 match the size and profile of the link 211, that is, the width of the first chain slot 1813 and the second chain slot 1814 in the first horizontal direction is slightly larger than the width of the link 211, and the width of the first chain slot 1813 and the second chain slot 1814 in the second horizontal direction is slightly larger than the thickness of the link 211, and the first horizontal direction and the second horizontal direction are perpendicular.

[0075] When winding the anchor chain 21, the reel of the anchor winch slowly rotates to store the anchor chain 21, and the first nozzle 15 sprays water to the first channel 1311 to clean the anchor chain 21. When the anchor chain 21 enters the chain barrel from bottom to top, it is first cleaned by the friction of the brush sheet 191 to remove some mud or seabed plants that are easy to fall. When the link 211 of the anchor chain 21 moves to the bottom of the adjustment seat 181, if the link 211 is in a normal state and has been aligned with the position of the first chain slot 1813 or the second chain slot 1814, the link 211 directly passes through the first chain slot 1813 or the second chain slot 1814. If the link 211 is not aligned with the first chain groove 1813 or the second chain groove 1814, the link 211 pushes the adjustment seat 181 upward, and the adjustment seat 181 moves upward and rotates under the guidance of the spiral slide groove 137, so that the link 211 is aligned with the first chain groove 1813 or the second chain groove 1814. After the link 211 is aligned with the first chain groove 1813 or the second chain groove 1814, the upper end of the link 211 first enters the first chain groove 1813 or the second chain groove 1814, and the adjustment seat 181 quickly slides downward and resets under the action of the first spring 186. If the lower end of the link 211 is misaligned, the link 211 returns to its normal position under the guidance of the inner wall of the first chain groove 1813 or the inner wall of the second chain groove 1814, thereby completing the adjustment of the position of the link 211. After the previous link 211 is adjusted, if the next link 211 is in a normal position, it will automatically enter the first chain slot 1813 or the second chain slot 1814. If it is not normal, the next link 211 will also be automatically corrected according to the above process. After each link 211 is adjusted, it moves to the first channel 1311 for flushing.

[0076] In this way, by correcting each link 211 one by one, the anchor chain 21 can be easily wound up.

[0077] When the anchor chain 21 is released, the anchor chain 21 moves downward under the action of gravity, and the relative positions of the links 211 are adjusted again by the adjustment seat 181 and the second spring 187 to ensure that the length of the anchor chain 21 composed of the links 211 is the longest.

[0078] In some embodiments, in order to improve the discharge efficiency of the liquid sprayed by the first nozzle 15, a plurality of waste discharge holes 1816 are provided on the adjustment seat 181. The plurality of waste discharge holes 1816 are arranged at intervals and penetrate the adjustment seat 181 from top to bottom. The first chain groove 1813 and the second chain groove 1814 are located in the area enclosed by the plurality of waste discharge holes 1816. The liquid sprayed by the first nozzle 15 flushes the sludge and is discharged from the waste discharge holes 1816 to the third channel 1313, and finally discharged into the sea.

[0079] Optionally, a scraper 1815 is provided on the inner wall of the first chain groove 1813 and the second chain groove 1814. When the link 211 enters the first chain groove 1813 and the second chain groove 1814, the scraper 1815 abuts against the link 211, thereby scraping away the sludge or seaweed and other plants that are difficult to clean on the link 211, causing the sludge or seaweed and other plants to fall off or loosen, thereby facilitating flushing of the first nozzle 15.

[0080] In some embodiments, the upper end surface of the adjustment seat 181 is provided with a first guide groove 1811, and the lower end surface of the joint seat is provided with a first guide groove 1811 and a second guide groove 1812. The first guide groove 1811 and the second guide groove 1812 are both annular grooves. One end of the first spring 186 is connected to the first positioning ring 133, and the other end of the first spring 186 is provided with a first positioning seat, and the first positioning seat is equipped with a first ball 183, and the first ball 183 can rotate in all directions. One end of the second spring 187 is connected to the second positioning ring 134, and the other end of the second spring 187 is provided with a second positioning seat, and the second positioning seat is equipped with a second ball 184, and the first ball 183 can rotate in all directions. When the adjustment seat 181 is installed in the second channel 1312, the first ball 183 abuts against the bottom wall of the first guide groove 1811, and the second ball 184 abuts against the bottom wall of the second guide groove 1812, thereby reducing the friction when the adjustment seat 181 rotates.

[0081] It is understandable that, in order to reduce the friction between the slide 182 and the inner wall of the spiral slide groove 137, a third ball 185 is installed on the slide 182, and the third ball 185 can rotate in all directions.

[0082] When the cabin ventilation device of this embodiment reels the anchor chain 21, the anchor chain 21 is first cleaned by the brush sheet 191, and then cleaned by the scraper 1815 on the adjustment seat 181, and most of the sludge and seaweed and other plants are removed, and finally flushed by the first nozzle 15 to ensure the cleaning effect of the anchor chain 21. Since the first hole 1311 is connected to the ventilation pipe 11, the anchor chain 21 is first cleaned twice in the second hole 1312 and the third hole 1313 located below the first hole 1311, and the liquid sprayed by the first nozzle 15 flows from top to bottom to flush the anchor chain 21, so that the cleanliness of the anchor chain 21 when entering the first hole 1311 is greatly improved, and the possibility of the odor of the attachment on the anchor chain 21 being emitted from the first hole 1311 to the ventilation pipe 11 is reduced, and the air in the cabin 202 is prevented from having odor when ventilating.

[0083] In addition, an air purifier or material may be disposed in the ventilation tube 11 or the first connecting tube 12 to purify the air.

[0084] In general, the cabin ventilation device optimizes the pipeline layout, making the design more concise, meeting the functions of ventilation and cleaning, reducing the pipeline layout, optimizing the freeboard deck 201 space layout, reducing the manufacturing cost and installation cost for the shipyard, and being more convenient for the shipowner to use, reducing the pipeline layout, and making it more convenient to maintain. Especially when there are many cabins 202, a large amount of pipeline materials can be saved, reducing the workload of the shipyard and reducing the maintenance cost.

[0085] At the same time, if Figures 1 to 3 As shown, the embodiment of the present application also provides a ship, including a hull 20 and the above-mentioned cabin ventilation device; the hull 20 has a freeboard deck 201 and a cabin 202. The ventilation pipe 11 and the chain pipe 13 are both installed on the freeboard deck 201, and the ventilation pipe 11 is strengthened by the rib plate 203 when installed on the freeboard deck 201. The cabin 202, the ventilation pipe 11, the first connecting pipe 12, and the conveying channel 131 of the chain pipe 13 are connected in sequence.
