Description

Technical Field

[0001] This disclosure relates to the field of marine equipment technology, and in particular to a water intake device and a ship. Background Technology

[0002] To mitigate the impact of aquaculture on nearshore waters, expand aquaculture space, and achieve sustainable development of marine aquaculture, aquaculture workboats are typically used for deep-sea aquaculture. These workboats are enclosed marine aquaculture systems with autonomous navigation capabilities, allowing them to select sea areas with suitable water temperatures according to seasonal changes and proactively avoid natural disasters such as super typhoons.

[0003] In related technologies, aquaculture vessels are all equipped with water intake devices, which include a water intake pump, a telescopic pipe, a hinge, and a winch. The telescopic pipe consists of an outer pipe and an inner pipe that are coaxially inserted. One end of the inner pipe is connected to the inlet of the water intake pump, and the other end of the inner pipe is movably inserted into the outer pipe. The hinge passes through the gap between the outer and inner pipes into the outer pipe and extends to the end of the outer pipe away from the inner pipe and connects to the end of the outer pipe. In this way, the telescopic pipe can be extended or retracted by the winch by retrieving or releasing the hinge, so that the outer pipe can extend to different depths in the seawater to collect water.

[0004] However, the hinge is located between the outer and inner pipes, which increases the sliding friction between them and affects the extension and retraction of the telescopic pipe. Furthermore, the gap between the outer and inner pipes in the telescopic pipe does not form an effective seal, and seawater can easily overflow from the gap between the outer and inner pipes during water intake, affecting water intake efficiency. Summary of the Invention

[0005] This disclosure provides a water intake device and vessel that can improve the problem of seawater overflowing from pipes during water intake, thereby increasing water intake efficiency. The technical solution is as follows:

[0006] This disclosure provides a water intake device, comprising: a water intake pipe, a water intake assembly, a sealing assembly, and a telescopic assembly. The water intake assembly and the telescopic assembly are arranged axially at intervals on the outer wall of the water intake pipe. The telescopic assembly is used to drive the water intake pipe to extend or retract axially. The outer wall of the water intake pipe has a plurality of axially spaced water intake ports. The sealing assembly is located inside the water intake pipe and is used to seal or open each of the water intake ports. The water intake assembly includes a water intake tank and a water intake pump. The water intake tank has a water inlet. The water intake pump is located outside the water intake tank and communicates with the water inlet. The side of the water intake tank opposite to the water intake pipe has an opening for docking with the water intake ports.

[0007] In one implementation of this disclosure, the inner wall of the water tank has a baffle that divides the water tank into a first cavity and a second cavity. The water inlet is connected to the first cavity, and the baffle has a through hole. The water intake assembly further includes a telescopic tube with an outer flange on its wall. The telescopic tube is inserted into the through hole, and the outer flange is sealed to the baffle. The telescopic tube is located in the second cavity and is used to connect with the water inlet.

[0008] In another implementation of this disclosure, the telescopic pipe includes a telescopic rod, a first pipe segment, a flexible hose, and a second pipe segment. The first pipe segment, the flexible hose, and the second pipe segment are connected in sequence. One end of the telescopic rod is connected to the first pipe segment, and the other end of the telescopic rod is connected to the second pipe segment.

[0009] In another implementation of this disclosure, the end of the telescopic tube away from the baffle has an annular groove, the water intake assembly further includes an air bladder and an inflation component, the air bladder is located in the annular groove, and the inflation component is used to inflate the air bladder; the inner hole of the water intake port is provided with an inner flange, and the end of the telescopic tube away from the baffle is inserted into the water intake port and abuts against the inner flange.

[0010] In another implementation of this disclosure, an annular sealing gasket is provided between the baffle and the outer flange.

[0011] In another implementation of the present disclosure, the sealing assembly includes a sealing tube and a rotating component. The sealing tube is coaxially inserted into the water intake pipe, and the outer wall surface of the sealing tube is in contact with the inner wall surface of the water intake pipe. The tube wall of the sealing tube has a plurality of axially spaced communication ports, and each of the communication ports is distributed circumferentially along the sealing tube. The rotating component is used to drive the sealing tube to rotate.

[0012] In another implementation of the present disclosure, the telescopic component includes at least two racks, at least two gears, and a drive motor. The racks and gears correspond one-to-one, and the racks mesh with the corresponding gears. The drive motor is used to drive the gears to rotate. At least two racks are located on the outer wall of the water intake pipe, and the at least two racks are symmetrically distributed about the central axis of the water intake pipe.

[0013] In another implementation of this disclosure, the water intake device further includes a temperature sensor located at the end of the water intake pipe inserted into the seawater.

[0014] In another implementation of the present disclosure, the water intake device further includes a cylindrical grille, one end of which is connected to the end of the water intake pipe inserted into the seawater.

[0015] This disclosure provides a vessel that includes the water intake device as described above.

[0016] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0017] In the water intake device provided in this embodiment, the water intake assembly and the telescopic assembly are distributed at intervals along the axial direction of the water intake pipe. The telescopic assembly can control the axial movement of the water intake pipe. The pipe wall of the water intake pipe is provided with axially distributed water intake ports. In this way, during the process of the telescopic assembly controlling the axial movement of the water intake pipe, different water intake ports on the water intake pipe can be aligned with the water intake assembly. The water intake assembly includes a water intake tank and a water intake pump. The water intake pump is located outside the water intake tank and is connected to the water inlet of the water intake port. When the water intake port of the water intake pipe moves to align with the opening on the side of the water intake tank, the seawater in the water intake pipe will enter the water intake tank through the water intake port and the opening, and then be pumped into the aquaculture pond by the water intake pump.

[0018] Compared to the telescopic pipes using inner and outer tubes in related technologies, the water intake pipe consists of only a single pipe, simplifying its structure. It directly uses a telescopic assembly to control the axial movement of the water intake pipe to achieve telescopic extension, avoiding the problem of increased pipe extension resistance caused by hinges being placed between the outer and inner tubes when using hinge traction. When drawing seawater at different depths, the connection between the water intake ports and the openings of the water tank is controlled at different locations, and the remaining intake ports are sealed using a sealing assembly. This prevents seawater overflow during water intake and improves water intake efficiency. Attached Figure Description

[0040] Figure 1 This is a schematic diagram of the structure of a water intake device provided in an embodiment of this disclosure. Figure 1 As shown, the water intake device includes: a water intake pipe 10, a water intake assembly, a sealing assembly, and a telescopic assembly 30. The water intake assembly and the telescopic assembly 30 are arranged at intervals along the axial direction of the water intake pipe 10 on the outer wall of the water intake pipe 10. The telescopic assembly 30 is used to drive the water intake pipe 10 to extend and retract along the axial direction.

[0041] Figure 2 This is a schematic diagram of the structure of a water intake device provided in an embodiment of this disclosure. Figure 2 The illustrated water intake device and Figure 1 The difference is that, Figure 2 The water intake pipe 10 in the middle is relative to Figure 1 The water intake pipe 10 extends downwards a certain distance, that is... Figure 2 The water intake pipe 10 in the middle is relative to Figure 1 The water intake pipe 10 extends further into the ocean.

[0042] like Figure 2 As shown, the outer wall of the water intake pipe 10 has multiple water intake ports 11 arranged axially at intervals. The sealing assembly is located inside the water intake pipe 10 and is used to seal or open each water intake port 11.

[0043] Figure 3 This is a partial schematic diagram of the water tank 20 and water pipe 10 provided in an embodiment of this disclosure. Figure 3As shown, the water intake assembly includes a water intake tank 20 and a water intake pump 21. The water intake tank 20 has a water inlet 200. The water intake pump 21 is located outside the water intake tank 20 and is connected to the water inlet 200. The side of the water intake tank 20 opposite to the water intake pipe 10 has an opening for docking with the water inlet 11.

[0044] In the water intake device provided in this embodiment, the water intake component and the telescopic component 30 are distributed at intervals along the axial direction of the water intake pipe 10. The telescopic component 30 can control the axial movement of the water intake pipe 10. The pipe wall of the water intake pipe 10 is provided with axially distributed water intake ports 11. In this way, during the process of the telescopic component 30 controlling the axial movement of the water intake pipe 10, different water intake ports 11 on the water intake pipe 10 can be aligned with the water intake component. The water intake component includes a water intake tank 20 and a water intake pump 21. The water intake pump 21 is located outside the water intake tank 20 and is connected to the water inlet of the water intake port 11. When the water intake port 11 of the water intake pipe 10 moves to connect with the opening on the side of the water intake tank 20, the seawater in the water intake pipe 10 will enter the water intake tank 20 through the water intake port 11 and the opening, and then be pumped into the aquaculture pond by the water intake pump 21.

[0045] Compared to the telescopic pipe 22, which uses an inner and outer pipe set in related technologies, the water intake pipe 10 only includes a single pipe, simplifying the structure of the water intake pipe 10. It directly uses the telescopic component 30 to control the axial movement of the water intake pipe 10 to achieve the purpose of telescopic movement, avoiding the problem of increased pipe telescopic resistance caused by the hinge being set between the outer and inner pipes when a hinge traction is set. When it is necessary to extract seawater at different depths, the connection between the water intake port 11 at different positions and the opening of the water intake tank 20 is controlled, and the remaining water intake ports 11 are sealed with a sealing component. This can avoid the problem of seawater overflow during the water intake process and improve the water intake efficiency.

[0046] In this embodiment of the disclosure, the distribution spacing of the water inlets 11 in the water inlet pipe 10 is 4m to 6m, for example, the distribution spacing of the water inlets 11 is 5m.

[0047] For example, the water intake pipe 10 is made of steel pipe, and both the inner and outer sides of the water intake pipe 10 are coated with anti-corrosion and anti-marine organism coatings.

[0048] Optionally, such as Figure 3 As shown, the inner wall of the water tank 20 has a baffle 203, which divides the water tank 20 into a first cavity 201 and a second cavity 202. The water inlet 11 is connected to the first cavity 201, and the baffle 203 has a through hole.

[0049] like Figure 3 As shown, the water intake assembly also includes a telescopic pipe 22. The wall of the telescopic pipe 22 is provided with an outer flange 221. The telescopic pipe 22 is inserted into the through hole, and the outer flange 221 is sealed and connected to the baffle 203. The telescopic pipe 22 is located in the second cavity 202 and is used to connect with the water intake port 11.

[0050] In the above implementation, the baffle 203 divides the water tank 20 into two chambers. The first chamber 201 is used for water storage for the water pump 21 to draw water, and the second chamber 202 is used to install the telescopic pipe 22, providing a certain amount of space for the telescopic pipe 22 to expand and contract. An outer flange 221 is provided on the wall of the telescopic pipe 22. After the telescopic pipe 22 is inserted into the through hole of the baffle 203, the outer flange 221 abuts against the baffle 203. The outer flange 221 and the baffle 203 can be fixed together using connecting bolts or other connecting components, so that the telescopic pipe 22 can be fixedly installed inside the water tank 20.

[0051] For example, such as Figure 3 As shown, an annular sealing gasket 50 is provided between the outer flange 221 and the baffle 203. This can prevent seawater entering the first cavity 201 from leaking through the gap between the outer flange 221 and the baffle 203, thus improving the sealing performance.

[0052] For example, the annular sealing gasket 50 can be a rubber gasket.

[0053] Optionally, such as Figure 3 As shown, the telescopic pipe 22 includes a telescopic rod 222, a first pipe section 223, a flexible hose 224, and a second pipe section 225. The first pipe section 223, the flexible hose 224, and the second pipe section 225 are connected in sequence. One end of the telescopic rod 222 is connected to the first pipe section 223, and the other end of the telescopic rod 222 is connected to the second pipe section 225.

[0054] A flexible hose 224 is installed between the first pipe section 223 and the second pipe section 225, and a telescopic rod 222 is installed on the first pipe section 223 and the second pipe section 225. When the telescopic rod 222 extends or retracts, it causes the first pipe section 223 and the second pipe section 225 to move away from or closer to each other, thereby achieving the purpose of extending or retracting the second pipe section 225 relative to the first pipe section 223.

[0055] When the water intake port 11 of the water intake pipe 10 and the second cavity 202 of the water intake tank 20 are aligned, the second pipe section 225 is driven into the water intake port 11 by the telescopic rod 222, ensuring that seawater can flow smoothly from the water intake pipe 10 to the first cavity 201 for extraction by the water pump 21. After the water pump 21 has finished extracting water, the telescopic rod 222 is controlled to drive the second pipe section 225 to retract from the water intake port 11 to avoid the second pipe section 225 affecting the axial movement of the water intake pipe 10.

[0056] Optionally, such as Figure 3 As shown, the end of the telescopic tube 22 away from the baffle 203 has an annular groove 226. The water intake assembly also includes an airbag 23 and an inflation component 24. The airbag 23 is located in the annular groove 226, and the inflation component 24 is used to inflate the airbag 23.

[0057] For example, the annular groove 226 is located at the end face of the second section 225 of the telescopic tube 22, and the airbag 23 is contained within the annular groove 226. When the airbag 23 is not inflated, the airbag 23 does not protrude from the end face of the second section 225.

[0058] like Figure 3 As shown, the inner hole of the water inlet 11 is provided with an inner flange 12, and the end of the telescopic tube 22 away from the baffle 203 is inserted into the water inlet 11 and abuts against the inner flange 12.

[0059] In the above implementation, an inner flange 12 corresponding to the second pipe section 225 is also provided on the inner wall of the water intake 11. The inner flange 12 is used to abut against the second pipe section 225 so that after the second pipe section 225 is inserted into the water intake 11, it is limited by the inner flange 12, indicating that the second pipe section 225 has moved into place.

[0060] After the end face of the second pipe section 225 abuts against the inner flange 12, the airbag 23 in the annular groove 226 located on the end face of the second pipe section 225 is inflated by the air inflator 24, so that the airbag 23 fills the entire annular groove 226. At this time, the airbag 23 will also squeeze the surface of the inner flange 12. Under the pressure of the gas in the airbag 23, the airbag 23 and the inner flange 12 can be tightly fitted, thereby improving the sealing between the second pipe section 225 and the inner flange 12. This can prevent seawater in the water intake pipe 10 from leaking from the gap between the second pipe section 225 and the inner flange 12.

[0061] For example, such as Figure 3 The inflator 24 can be an air pump located in the second cavity 202. The second pipe section 225 has a channel extending to the annular groove 226 on its pipe wall. An air supply pipe is provided in the channel. One end of the air supply pipe is connected to the air pump, and the other end of the air supply pipe is connected to the air bag 23, so as to enable the air pump to inflate the air bag 23 in the annular groove 226 in the second cavity 202.

[0062] For example, a through hole communicating with the second cavity 202 can also be provided on the water tank 20, and a one-way valve is installed in the through hole.

[0063] In this embodiment, the second chamber 202 can also be used to collect leaked seawater, including seawater leaking from the first chamber 201 into the second chamber 202 and seawater leaking from the gap between the water intake pipe 10 and the second pipe section 225 into the second chamber 202. When the amount of seawater leaked into the second chamber 202 reaches a certain level, and the pressure of the seawater in the second chamber 202 exceeds the pressure relief pressure of the one-way valve, the seawater is discharged from the second chamber 202 to avoid storing too much leaked seawater in the water intake tank 20.

[0064] Alternatively, the check valve can be connected to the aquaculture pond via a pipeline, which can also transport leaked seawater to the aquaculture pond, improving water intake efficiency.

[0065] Figure 4 This is a schematic diagram of the structure of a water intake pipe 10 provided in an embodiment of this disclosure. Figure 4 As shown, the sealing assembly includes a sealing tube 41 and a rotating component 42. The sealing tube 41 is coaxially inserted into the water intake pipe 10, and the outer wall surface of the sealing tube 41 is in contact with the inner wall surface of the water intake pipe 10. The tube wall of the sealing tube 41 has multiple axially spaced communication ports 43, and each communication port 43 is distributed circumferentially along the sealing tube 41. The rotating component 42 is used to drive the sealing tube 41 to rotate.

[0066] In this embodiment, multiple connecting ports 43 in the sealing pipe 41 are spirally distributed on the sealing pipe 41, while the water inlets 11 on the water inlet pipe 10 are axially distributed along the central axis of the water inlet pipe 10. Thus, when one connecting port 43 in the sealing pipe 41 rotates to face the water inlet 11 in the water inlet pipe 10, the other connecting ports 43 in the sealing pipe 41 will not face the other water inlets 11 in the water inlet pipe 10, thereby achieving the purpose of opening one water inlet 11 while closing the other water inlets 11.

[0067] For example, such as Figure 4 The rotating component 42 can be a rotary motor. One end of the sealing tube 41 protrudes from the water intake pipe 10. A gear ring 44 is fitted onto the end of the sealing tube 41 that protrudes from the water intake pipe 10. The rotating shaft of the rotary motor meshes with the gear ring 44 through the gear 32, thereby driving the gear ring 44 to rotate, so as to drive the sealing tube 41 to rotate inside the water intake pipe 10.

[0068] Figure 5 This is a top view of a water intake device provided in an embodiment of this disclosure. Figure 6 yes Figure 5 The provided AA cross-sectional diagram. (For example...) Figure 5 , 6 As shown, the telescopic component 30 includes at least two racks 31, at least two gears 32 and a drive motor 33. The racks 31 and gears 32 are in one-to-one correspondence, and the racks 31 mesh with the corresponding gears 32. The drive motor 33 is used to drive the gears 32 to rotate. At least two racks 31 are located on the outer wall of the water intake pipe 10, and at least two racks 31 are symmetrically distributed about the central axis of the water intake pipe 10.

[0069] For example, the telescopic assembly 30 can be installed on the deck 71 of a ship. The telescopic assembly 30 also includes a gearbox 34, the input shaft of which is connected to the drive motor 33, and the output shaft of which is connected to the gear 32. In this way, the shaft of the drive motor 33 inputs power to the gearbox 34, and the power is transmitted from the output shaft of the gearbox 34 to the gear 32, thereby driving the meshing rack 31 to move up and down, so as to achieve the purpose of driving the water intake pipe 10 to move axially.

[0070] Optionally, the water intake device also includes a temperature sensor located at the end of the water intake pipe 10 that is inserted into the seawater.

[0071] By setting up temperature sensors, the temperature of the seawater can be detected, so that technicians can determine whether the seawater at the current depth meets the temperature requirements for aquaculture, making it easier to collect water.

[0072] Optionally, such as Figure 1 , 2 As shown, the water intake device also includes a cylindrical grille 60, one end of which is connected to the end of the water intake pipe 10 that is inserted into the seawater.

[0073] The cylindrical grille 60 has a cylindrical structure with multiple arrayed filter holes on its outer wall. These filter holes remove impurities larger than the filter holes, preventing them from being drawn into the aquaculture pond.

[0074] For example, the total area of ​​the cylindrical grille 60 is at least twice the cross-section of the water intake pipe 10 to ensure smooth water intake.

[0075] This disclosure provides an embodiment of a ship, such as Figure 1 , 2 As shown, the vessel includes the water intake device as described above.

[0076] After the water intake device is installed on the ship, the different water intake ports 11 on the water intake pipe 10 can be aligned with the water intake component during the axial movement controlled by the telescopic component 30. When the water intake port 11 of the water intake pipe 10 moves to connect with the opening on the side of the water intake tank 20, the seawater in the water intake pipe 10 will enter the water intake tank 20 through the water intake port 11 and the opening, and then be pumped into the aquaculture pond by the water intake pump 21.

[0077] Compared to the telescopic pipe 22, which uses an inner and outer pipe set in related technologies, the water intake pipe 10 only includes a single pipe, simplifying the structure of the water intake pipe 10. It directly uses the telescopic component 30 to control the axial movement of the water intake pipe 10 to achieve the purpose of telescopic movement, avoiding the problem of increased pipe telescopic resistance caused by the hinge being set between the outer and inner pipes when a hinge traction is set. When it is necessary to extract seawater at different depths, the connection between the water intake port 11 at different positions and the opening of the water intake tank 20 is controlled, and the remaining water intake ports 11 are sealed with a sealing component. This can avoid the problem of seawater overflow during the water intake process and improve the water intake efficiency.

[0078] In this embodiment of the present disclosure, a moon pool 73 is provided on the deck 71 of the ship. The moon pool 73 extends from the deck 71 to the bottom 72 of the ship. A water intake pipe 10 is inserted in the moon pool 73, and one end of the water intake pipe 10 extends from the bottom 72 into the seawater.

[0079] The diameter of the moon pool 73 is larger than the diameter of the water intake pipe 10, and the diameter of the moon pool 73 is 6mm to 8mm larger than the diameter of the water intake pipe 10.

[0080] Optionally, the inner wall of the moon pool 73 is provided with a groove, which corresponds one-to-one with the rack 31. The groove is provided to accommodate the rack 31 on the water intake pipe 10, so that the rack 31 will not rub against the inner wall of the moon pool 73 during the extension and retraction of the water intake pipe 10 relative to the moon pool 73.

[0081] For example, a vessel equipped with a water intake device can be an aquaculture vessel. When the aquaculture vessel sails to a selected sea area, the telescopic assembly 30 on the deck 71 is activated to control the rise or fall of the water intake pipe 10. Simultaneously, the temperature sensor at the bottom of the water intake pipe 10 measures the seawater temperature at that location. When the seawater temperature meets the aquaculture requirements, the position of the water intake pipe 10 is slightly adjusted to ensure that the water intake port 11 on the water intake pipe 10 is aligned with the telescopic pipe 22 of the water tank 20, and then the telescopic assembly 30 is stopped. The telescopic pipe 22 of the water tank 20 is activated so that the second section 225 of the telescopic pipe 22 connects with the water intake port 11 of the water intake pipe 10, and then air is inflated into the airbag 23 for sealing, thus establishing the connection of the water intake channel. Then, the sealing pipe 41 is rotated to seal the remaining water intake ports 11, leaving only the water intake port 11 at the connection between the water intake pipe 10 and the water tank 20 open. Then, the water pump 21 is activated to quickly extract water from the required depth.

[0082] When encountering severe weather or other natural conditions, the water intake pipe 10 can be raised directly from the deep sea. Without much operation, the vessel can start sailing and quickly leave the dangerous sea area.

[0083] The above is not intended to limit this disclosure in any way. Although this disclosure has been disclosed above through embodiments, it is not intended to limit this disclosure. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of this disclosure. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this disclosure without departing from the content of the technical solution of this disclosure shall still fall within the scope of the technical solution of this disclosure.
