Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a seawater collection system and a scientific research vessel. Background Art

[0002] Major discoveries in marine science research are often obtained from long-term observations. Without long-term and large-scale field observations, it is almost impossible to achieve major breakthroughs. For example, the discovery of ocean circulation, mesoscale vortex phenomena, El Niño phenomenon, periodic changes in marine biological resources, and the evolution of the marine environment are all based on long-term, large-scale and extensive marine field observation data. Changes in physical, chemical, biological, and ecological indicators of surface waters in the sea (water) area are basic data for understanding climate change and the impact of human activities on marine ecosystems. They are also an important basic support for predicting and forecasting the changing trends of major marine phenomena and conducting in-depth research on the mechanisms of marine processes.

[0030] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] like Figure 1 As shown, this embodiment provides a seawater collection system, which is configured on a scientific research vessel and is used for continuously collecting surface seawater while the scientific research vessel is sailing at sea. The seawater collection system includes a first water intake pipeline assembly and a second water intake pipeline assembly, the first water intake pipeline assembly includes a first filter 2 and a first liquid pump 3 connected by a first liquid inlet pipe 1, and the second water intake pipeline assembly includes a second filter 9 and a second liquid pump 10 connected by a second liquid inlet pipe 8. The liquid inlet of the first filter 2 is connected to a first water intake 101 arranged at the bottom of the ship, the liquid inlet of the second filter 9 is connected to a second water intake 102 arranged on the side of the hull 100, and the liquid outlets of the first liquid pump 3 and the second liquid pump 10 are connected to a water ecological monitoring station installed on the ship through a liquid outlet pipe 15, which is used to pump the surface seawater collected from the bottom or side of the ship to the water ecological monitoring station on the ship.

[0035] The first water intake pipeline assembly and the second water intake pipeline assembly are redundantly set. In the same period, only one water intake pipeline assembly needs to work. When the filter of one of the water intake pipeline assemblies is blocked by floating ice, it can be switched to the other one to continuously collect seawater. It is specifically implemented by the following scheme. A pressure sensor 16 is installed on the liquid outlet pipe 15. If the working first pipeline assembly is blocked by floating ice, the pressure sensor 16 detects that the outlet pressure of the first liquid pump 3 is less than the set value. At this time, the first water intake pipeline assembly can be electrically or manually closed, and the second water intake pipeline assembly can be opened to prevent water collection interruption. If the second water intake pipeline assembly is blocked, the switching principle is the same. A flow meter 17 is also installed on the liquid outlet pipe 15 to detect the flow rate of the outlet liquid.

[0036] Specifically, the first water intake pipeline assembly also includes a ship bottom water inlet valve 4, a first remote control valve 5 and a second remote control valve 6 installed on the first liquid inlet pipe 1. The ship bottom water inlet valve 4 is connected to the first water intake port 101, and is a manual valve that is normally open under normal conditions. The first remote control valve 5 is connected in series between the ship bottom water inlet valve 4 and the first filter 2, and the second remote control valve 6 is connected in series between the first filter 2 and the first liquid pump 3. The first remote control valve 5 and the second remote control valve 6 are opened and closed by electrical remote control.

[0037] Furthermore, the first water intake pipeline assembly also includes a first discharge valve 7, which is installed on a first discharge pipe connected to the bottom of the first liquid inlet pipe 1, and is used to discharge seawater in the first pipeline assembly into the sea when the system is not working.

[0038] In order to ensure the normal operation of the first water intake pipeline assembly, the first liquid pump 3 needs to meet the following conditions: the operation of the pump must be safe and reliable; the pump casing, mechanical seal, etc. of the pump will not pollute the water body; the pump will not damage the microorganisms, algae, etc. in the seawater when it is running; the flow pressure can be well adjusted; and it can also work normally for seawater containing particles such as crushed ice. In this embodiment, preferably, the first liquid pump 3 uses a rotor pump. The rotor pump is a volumetric pump, which achieves the purpose of conveying fluid by means of the periodic conversion of multiple fixed volume conveying units in the working chamber. It is characterized by simple structure, few parts, easy maintenance, and high reliability. There is an isolation chamber between the pump chamber and the gear box of the rotor pump to avoid oil contamination of seawater; the rotor is made of rubber material to avoid heavy metal and oil contamination of seawater; the rotor pump is driven by a frequency converter to accurately control the flow of the pump; there are gaps between the rotors, which will not damage microorganisms and algae in the seawater; the rotor pump can transport seawater with crushed ice without causing damage to the pump itself; the mechanical seal of the pump is lubricated, and after the pipeline is blocked by crushed ice, the pump unit will not be damaged even if it is dry-running without water in the pipeline.

[0039] The working mode of the first water intake pipeline assembly is as follows: the first liquid pump 3 is running, and the ship bottom water inlet valve 4, the first remote control valve 5 and the second remote control valve 6 are opened, and the liquid outlet valve 18 on the liquid outlet pipe 15 is opened, and the first discharge valve 7 is closed. The seawater on the bottom of the ship passes through the valves installed on the first liquid inlet pipe 1, the first filter 2 and the first liquid pump 3 in turn, and finally flows into the water ecological monitoring station on the ship through the liquid outlet pipe 15. The first liquid inlet pipe 1 is also equipped with a thermometer 21 and a pressure gauge 22, which are used to display the temperature and pressure of the seawater in real time. When the first filter 2 is blocked by floating ice, the pressure sensor 16 installed on the liquid outlet pipe 15 detects that the outlet pressure of the first liquid pump 3 is less than the set value. At this time, the first liquid pump 3 stops working, the first discharge valve 7 is opened, and the seawater in the first water intake pipeline assembly flows into the sea through the first discharge valve 7. At the same time, the second liquid pump 10 starts working, and the second water intake pipeline assembly is turned on.

[0040] In addition to the second filter 9 and the second liquid pump 10, the second water intake pipeline assembly also includes a side water inlet valve 11, a third remote control valve 12 and a fourth remote control valve 13 installed on the second liquid inlet pipe 8. Among them, the side water inlet valve 11 is connected to the second water intake port 102, which is a manual valve and is normally open under normal conditions. The third remote control valve 12 is connected in series between the side water inlet valve 11 and the second filter 9, and the fourth remote control valve 13 is connected in series between the second filter 9 and the second liquid pump 10. The third remote control valve 12 and the fourth remote control valve 13 are opened and closed by electrical remote control to control the opening and closing of the second liquid inlet pipe 8.

[0041] Furthermore, the second water intake pipeline assembly also includes a second discharge valve 14, which is installed on a second discharge pipe connected to the bottom of the second liquid inlet pipe 8, and is used to discharge the seawater in the second pipeline assembly into the sea when the system is not working.

[0042] In the second water intake pipeline assembly, the second liquid pump 10 also uses a rotor pump to ensure the quality of the extracted surface seawater and the working stability of the system. The working mode of the second water intake pipeline assembly is as follows: the second liquid pump 10 is running, and the side water inlet valve 11, the third remote control valve 12 and the fourth remote control valve 13 are opened, while the liquid outlet valve 18 on the liquid outlet pipe 15 is opened, and the second discharge valve 14 is closed. The seawater on the side of the hull 100 flows through the various valves installed on the second liquid inlet pipe 8, the second filter 9 and the second liquid pump 10 in turn, and finally flows into the water ecological monitoring station on the ship through the liquid outlet pipe 15. A plurality of thermometers 21 and pressure gauges 22 are also installed on the second liquid inlet pipe 8 for real-time display of the temperature and pressure of the seawater. When the second filter 9 is clogged by floating ice, the pressure sensor 16 installed on the liquid outlet pipe 15 detects that the outlet pressure of the second liquid pump 10 is less than the set value. At this time, the first liquid pump 3 stops working, the first discharge valve 7 opens, and the seawater in the second water intake pipeline assembly flows into the sea through the second discharge valve 14. At the same time, the first liquid pump 3 starts working, and the first water intake pipeline assembly is turned on.

[0043] Furthermore, a switching pipe 19 is provided between the liquid inlets of the first liquid pump 3 and the second liquid pump 10, and a switching valve 20 is installed on the switching pipe 19. The switching pipe 19 is used to connect the first liquid pump 3 with the second water intake 102 located on the side, and to connect the second liquid pump 10 with the first water intake 101 located on the bottom of the ship. Specifically, when the first liquid pump 3 is connected with the second water intake 102, the multiple valves installed on the second liquid inlet pipe 8 and the switching valve 20 are opened, and the multiple valves installed on the first liquid inlet pipe 1 are closed. When the second liquid pump 10 is connected with the first water intake 101, the multiple valves installed on the first liquid inlet pipe 1 and the switching valve 20 are opened, and the multiple valves installed on the second liquid inlet pipe 8 are closed. The setting of the switching pipe 19 and the switching valve 20 improves the flexibility of seawater collection. When one of the water intake pipeline components is blocked by floating ice, the water intake can be changed without switching the working state of the first liquid pump 3 and the second liquid pump 10.

[0044] The seawater collection system provided in this embodiment also includes a deicing pipeline assembly, which includes a deicing pipe 24 that connects the steam source and the compressed air source with the first filter 2 and the second filter 9, and a deicing stop valve installed on the deicing pipe 24. Specifically, the upstream branch of the deicing pipe 24 has two inlets, which are a steam interface 103 and a compressed air interface 104, respectively, and a steam stop valve 29 and a compressed air stop valve 30 are installed at the steam interface 103 and the compressed air interface 104, respectively. The downstream of the deicing pipe 24 is divided into a first deicing branch pipe 25 and a second deicing branch pipe 26, the first deicing branch pipe 25 is connected to the liquid outlet of the first filter 2, and the second deicing branch pipe 26 is connected to the liquid outlet of the second filter 9. The deicing stop valve includes a first deicing stop valve 27 installed on the first deicing branch pipe 25 and a second deicing stop valve 28 installed on the second deicing branch pipe 26.

[0045] When the first filter 2 is clogged with crushed ice, the first de-icing stop valve 27 is opened, and the steam stop valve 29 and / or the compressed air stop valve 30 are opened, and at the same time, the multiple valves installed on the first liquid inlet pipe 1 are all opened, and hot steam and / or high-pressure air are introduced into the first filter 2 to melt and remove the crushed ice in the first filter 2, and then the hot steam and / or compressed air are discharged into the sea through the first liquid inlet pipe 1 and the first water intake 101 along with the seawater melted with crushed ice. The principle of deicing in the second filter 9 is the same as that of the same filter. After the second filter 9 is de-iced, steam and / or compressed air are discharged into the sea from the second liquid inlet pipe 8 and the second water intake 102, and the specific deicing process is not repeated here. Furthermore, when it is not necessary to collect seawater, the seawater collection system provided in this embodiment can also de-ice the first water intake pipeline assembly and the second water intake pipeline assembly at the same time to improve the de-icing efficiency.

[0046] After the seawater collection system is put into operation for a period of time, some microorganisms may adhere to the system pipelines, which may pollute the sampled seawater quality. At this time, it is necessary to consider adding medicine to disinfect and clean the entire system. Therefore, the seawater collection system provided in this embodiment also includes a cleaning pipeline component.

[0047] The cleaning pipeline assembly includes a cleaning pipe 31 that connects the fresh water source and the cleaning agent source with the first water intake pipeline assembly and the second water intake pipeline assembly, and a cleaning stop valve installed on the cleaning pipe 31. Specifically, the upstream branch of the cleaning pipe 31 has two inlets, namely a fresh water interface 105 and a cleaning agent interface, wherein the cleaning agent interface is connected to the cleaning agent tank 37, and a fresh water stop valve 36 and a cleaning agent stop valve 38 are installed at the fresh water interface 105 and the cleaning agent interface, respectively. The cleaning pipe 31 is divided into a first cleaning branch pipe 32 and a second cleaning branch pipe 33 downstream, the first cleaning branch pipe 32 is connected to the liquid inlet of the first filter 2, and the second cleaning branch pipe 33 is connected to the liquid inlet of the second filter 9. The cleaning stop valve includes a first cleaning stop valve 34 installed on the first cleaning branch pipe 32 and a second cleaning stop valve 35 installed on the second cleaning branch pipe 33.

[0048] Furthermore, the cleaning pipeline assembly further includes a liquid return pipe 39 and a liquid return stop valve 40. The liquid return pipe 39 is connected in series between the liquid outlet pipe 15 and the cleaning pipe 31, and the liquid return stop valve 40 is installed on the liquid return pipe 39. The liquid return pipe 39 is used to form a cleaning loop to perform cyclic cleaning on the first water intake pipeline assembly and the second water intake pipeline assembly.

[0049] The working mode of the cleaning pipeline assembly is as follows. When there are too many microorganisms attached to the first water intake pipeline assembly: first, open the first discharge valve 7 to discharge the residual seawater in the first pipeline assembly; then close the first remote control valve 5, open the second remote control valve 6 and the return liquid stop valve 40, and open the fresh water stop valve 36 and the cleaning agent stop valve 38 at the same time, and the fresh water and the cleaning agent flow into the cleaning pipe 31 to mix and form a cleaning solution. At this time, the first liquid inlet pipe 1, the liquid outlet pipe 15 and the return liquid pipe 39 between the cleaning pipe 31, the first cleaning branch pipe 32, the first remote control valve 5 and the liquid outlet pipe 15 form a first cleaning circulation loop. The first liquid pump 3 operates to realize the circulation of the cleaning solution in the first cleaning circulation loop, thereby continuously cleaning the first liquid inlet pipe 1, the liquid outlet pipe 15, the first filter 2 and the first liquid pump 3 to remove the microorganisms attached to the above components. After cleaning is completed, the first liquid pump 3, the fresh water stop valve 36, the cleaning agent stop valve 38, the first cleaning stop valve 34 and the liquid return stop valve 40 are closed, the first remote control valve 5 is opened, and the remaining cleaning solution is discharged downward into the sea through the first liquid inlet pipe 1 and the first water intake 101.

[0050] The cleaning principle of the second water intake pipeline assembly is basically the same as that of the first pipeline assembly. After the second water intake pipeline assembly is cleaned, the cleaning solution is discharged into the sea through the second liquid inlet pipe 8 and the second water intake port 102. The specific cleaning process is not repeated here. Further, when seawater collection is not required, the seawater collection system provided in this embodiment can also clean the first water intake pipeline assembly and the second water intake pipeline assembly at the same time to improve the cleaning efficiency.

[0051] Furthermore, the seawater collection system provided in this embodiment also includes a controller 23, and the controller 23 is electrically connected to the first liquid pump 3, the second liquid pump 10, the pressure sensor 16, the flow meter 17 and each remote control valve. The controller 23 receives the pressure signal of the pressure sensor 16, and controls the opening and closing of the first liquid pump 3 and the second liquid pump 10 according to the pressure signal, and controls the opening and closing state of each remote control valve to complete the realization of various functions such as taking water from the bottom of the ship, taking water from the side, deicing and cleaning. The controller 23 can be a centralized or distributed controller. For example, the controller 23 can be a single chip microcomputer, or it can be composed of multiple distributed single chip microcomputers. The control program can be run in the single chip microcomputer to control the operation of each component. It is a prior art in this field and will not be repeated here.

[0052] All pipelines in the seawater collection system provided in this embodiment use stainless steel vacuum double-walled pipes. The inner and outer walls of the vacuum double-walled pipes are evacuated, which has good insulation and heat preservation effects, thereby maintaining the stability of the seawater temperature and ensuring the authenticity of the physical and chemical properties of the collected surface seawater. Alternatively, in other embodiments of the present invention, a design of coating an insulation layer on the outside of an ordinary liquid pipe can also be used to keep the seawater warm.

[0053] The working principle of the seawater collection system provided by this embodiment is described below in conjunction with the accompanying drawings:

[0054] During the voyage, the research vessel continuously collects surface seawater through the seawater collection system, and uses the water ecological monitoring station installed on the ship to continuously monitor the physical, chemical, biological and ecological indicators of the seawater, in order to predict and forecast the changing trends of major marine phenomena and provide an important basic support for in-depth research on the mechanisms of marine processes.

[0055] Under normal conditions, the seawater collection system collects surface seawater through the first water intake pipeline assembly. When collecting seawater, the ship's bottom water inlet valve 4, the first remote control valve 5, and the second remote control valve 6 installed on the first liquid inlet pipe 1 are all opened, and the liquid outlet valve 18 installed on the liquid outlet pipe 15 is opened at the same time. The first liquid pump 3 is operated to draw the surface seawater from the bottom of the ship into the first liquid inlet pipe 1, and after being filtered by the first filter 2, it finally flows into the water ecological monitoring station through the liquid outlet pipe 15. While the first liquid pump 3 is working, the controller 23 receives the value of the pressure sensor 16 installed on the liquid outlet pipe 15 in real time. When the liquid outlet pressure detected by the pressure sensor 16 is less than the set value, it means that the first filter 2 is blocked. At this time, the controller 23 controls the second liquid pump 10 to operate and controls the first liquid pump 3 to delay closing.

[0056] After the first filter 2 is blocked, the second liquid pump 10 is controlled by the controller 23 to start. At the same time, the controller 23 controls the side water inlet valve 11, the third remote control valve 12 and the fourth remote control valve 13 to open. The second liquid pump 10 draws surface seawater from the side of the hull into the second liquid inlet pipe 8. The seawater is filtered by the second filter 9 and finally flows into the water ecological monitoring station through the liquid outlet pipe 15.

[0057] When the second water intake pipeline assembly supplies water normally, the controller 23 controls the deicing pipeline assembly to de-ice the first water intake pipeline assembly at the same time. Specifically, the first deicing stop valve 27 is opened, and the steam stop valve 29 and / or the compressed air stop valve 30 are opened at the same time, and the hot steam and / or compressed air are introduced into the first filter 2 through the deicing pipe 24 and the first deicing branch pipe 25 to melt the crushed ice in the first filter 2, and then the hot steam and / or compressed air are discharged from the first water intake 101 along with the seawater with melted crushed ice.

[0058] When the first water intake pipeline assembly is supplying water normally, the system can also de-ice the second water intake pipeline assembly. The de-icing principle is similar to the above process and will not be described in detail.

[0059] When the system does not need to collect seawater, the first water intake pipeline assembly and the second water intake pipeline assembly can also be disinfected and cleaned. Now, the disinfection and cleaning of the first water intake pipeline assembly is used for explanation: the controller 23 controls the fresh water stop valve 36 and the cleaning agent stop valve 38 to open, and the fresh water and the cleaning agent flow into the cleaning pipe 31 and mix into a cleaning solution. At the same time, the controller 23 controls the first cleaning stop valve 34 and the return liquid stop valve 40 to open, and the first liquid pump 3 is started. The cleaning solution circulates in the first cleaning circulation loop composed of the cleaning pipe 31, the first liquid inlet pipe 1 and the return liquid pipe 39, thereby cleaning and disinfecting each section of the pipeline as well as the first filter 2 and the first liquid pump 3.

[0060] The principle of disinfection and cleaning of the second water intake pipeline assembly by this system is similar to the principle of disinfection and cleaning of the first water intake pipeline assembly, and will not be repeated here.

[0061] The present invention also provides a scientific research vessel, which is equipped with the above-mentioned seawater collection system, and the scientific research vessel is also equipped with a water ecological monitoring station for detecting and analyzing the surface seawater collected by the seawater collection system.
