The first water intake pipeline assembly and the second water intake pipeline assembly are arranged in a redundant mode, only one water intake pipeline assembly needs to work at the same time interval, and when the filter of the one water intake pipeline assembly is blocked by floating ice, the other water intake pipeline assembly can be switched to the other water intake pipeline assembly to continuously realize seawater collection. The liquid outlet pipe 15 is provided with the pressure sensor 16, if the working first pipeline assembly is blocked by floating ice, the pressure sensor 16 detects that the liquid outlet pressure of the first liquid pump 3 is smaller than a set value, at the moment, the first water taking pipeline assembly can be electrically or manually closed, and the second water taking pipeline assembly is opened, so that water taking interruption is prevented. If the second water intake pipeline component is blocked, the switching principle is also the same. The liquid outlet pipe 15 is also provided with a flowmeter 17 for detecting the flow of the liquid outlet.
Specifically, the first water intake pipeline assembly further comprises a bottom water inlet valve 4, a first remote control valve 5 and a second remote control valve 6 which are installed on the first liquid inlet pipe 1.

Further, the first water intake pipeline assembly further comprises a first discharge valve 7, which is installed on a first discharge pipe bypassing the bottom of the first liquid inlet pipe 1, and is used for discharging the seawater in the first pipeline assembly to the sea when the system does not work.
To ensure the normal operation of the first water intake pipe assembly, the first liquid pump 3 needs to satisfy the following conditions: the operation of the pump needs to be safe and reliable; the pump shell, the mechanical seal and the like of the pump can not pollute the water body; the pump can not damage microorganisms, algae and the like in seawater when in operation; the flow pressure can be well adjusted; the seawater containing particles such as crushed ice can also work normally. In the present embodiment, the first liquid pump 3 is preferably a rotor pump. The rotor pump belongs to a displacement pump, achieves the purpose of conveying fluid by means of periodic conversion of a plurality of fixed volume conveying units in a working cavity, and is characterized by simple structure, few parts, convenient maintenance and high reliability. An isolation cavity is arranged between the pump cavity of the rotor pump and the gear box, so that the pollution of oil to seawater is avoided; the rotor is made of rubber, so that the pollution of heavy metal and oil to seawater is avoided; the rotor pump is driven by the frequency converter, so that the flow of the pump can be accurately controlled; gaps exist among the rotors, so that microorganisms, algae and the like in seawater cannot be damaged; the rotor pump can convey the seawater with crushed ice, and the pump can not be damaged; the mechanical sealing belt of the pump is lubricated, and after the pipeline is blocked by crushed ice, the pump set cannot be damaged even if the pipeline is in dry grinding operation under the condition of no water.
The first water taking pipeline assembly works in the following modes: the first liquid pump 3 is operated and the bottom intake valve 4, the first remote control valve 5 and the second remote control valve 6 are opened while the outlet valve 18 on the outlet pipe 15 is opened and the first discharge valve 7 is closed. The seawater at the bottom of the ship sequentially flows into the aquatic ecological monitoring station on the ship through the valves arranged on the first liquid inlet pipe 1, the first filter 2 and the first liquid pump 3 and finally flows into the aquatic ecological monitoring station on the ship through the liquid outlet pipe 15. The first liquid inlet pipe 1 is also provided with a thermometer 21 and a pressure gauge 22 which are respectively used for displaying the temperature and the pressure of the seawater in real time. When the first filter 2 is blocked by floating ice, the pressure sensor 16 mounted on the liquid outlet pipe 15 detects that the liquid outlet pressure of the first liquid pump 3 is smaller than a set value, at this time, the first liquid pump 3 stops working, the first discharge valve 7 is opened, seawater in the first water intake pipeline assembly flows into the sea through the first discharge valve 7, meanwhile, the second liquid pump 10 starts working, and the second water intake pipeline assembly is conducted.
The second water intake pipeline assembly comprises a side water inlet valve 11, a third remote control valve 12 and a fourth remote control valve 13 which are arranged on the second liquid inlet pipe 8 besides the second filter 9 and the second liquid pump 10. The side water inlet valve 11 is connected to the second water intake 102, and is a manual valve normally open. The third remote control valve 12 is connected in series between the side water inlet valve 11 and the second filter 9, the fourth remote control valve 13 is connected in series between the second filter 9 and the second liquid pump 10, and the third remote control valve 12 and the fourth remote control valve 13 are opened and closed through electric remote control to control the on-off of the second liquid inlet pipe 8.
Further, the second water intake pipeline assembly further comprises a second discharge valve 14, which is installed on a second discharge pipe bypassing the bottom of the second liquid inlet pipe 8, and is used for discharging the seawater in the second pipeline assembly to the sea when the system does not work.
In the second water intake pipeline assembly, the second liquid pump 10 also adopts 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 taking pipeline assembly is as follows: the second liquid pump 10 is operated and the broadside intake valve 11, the third remote control valve 12 and the fourth remote control valve 13 are opened while the outlet valve 18 on the 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 valves mounted on the second intake pipe 8, the second filter 9 and the second pump 10 in sequence, and finally flows into the marine ecology monitoring station through the outlet pipe 15. The second liquid inlet pipe 8 is also provided with a plurality of thermometers 21 and pressure gauges 22 for displaying the temperature and the pressure of the seawater in real time. When the second filter 9 is blocked by floating ice, the pressure sensor 16 installed on the liquid outlet pipe 15 detects that the liquid outlet pressure of the second liquid pump 10 is smaller than a set value, at this time, the first liquid pump 3 stops working, the first discharge valve 7 is opened, seawater in the second water intake pipeline assembly flows into the sea through the second discharge valve 14, meanwhile, the first liquid pump 3 starts working, and the first water intake pipeline assembly is conducted.
Further, 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 mounted on the switching pipe 19. The switching pipe 19 is used to communicate the first liquid pump 3 with the second intake port 102 on the side and to communicate the second liquid pump 10 with the first intake port 101 on the bottom of the ship. Specifically, when the first liquid pump 3 communicates with the second water intake 102, the valves mounted on the second liquid intake pipe 8 and the switching valve 20 are opened, while the valves mounted on the first liquid intake pipe 1 are closed. When the second liquid pump 10 communicates with the first water intake 101, the valves installed on the first liquid intake pipe 1 and the switching valve 20 are opened, while the valves installed on the second liquid intake pipe 8 are closed. The arrangement of the switching pipe 19 and the switching valve 20 improves the flexibility of seawater collection, and when one of the water intake pipeline components is blocked by floating ice, the water intake can be changed without switching the working states of the first liquid pump 3 and the second liquid pump 10.
The seawater collecting system provided by the embodiment further comprises a deicing pipeline assembly, wherein the deicing pipeline assembly comprises a deicing pipe 24 for communicating a steam source and a compressed air source with the first filter 2 and the second filter 9, and a deicing stop valve arranged on the deicing pipe 24. Specifically, the upstream of the deicing pipe 24 branches into two inlets, which are a steam interface 103 and a compressed air interface 104, 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 de-icing pipe 24 is divided into a first de-icing branch 25 and a second de-icing branch 26, the first de-icing branch 25 being connected to the outlet of the first filter 2, and the second de-icing branch 26 being connected to the outlet of the second filter 9. The deicing cutoff valves include a first deicing cutoff valve 27 mounted on the first deicing manifold 25 and a second deicing cutoff valve 28 mounted on the second deicing manifold 26.
When the first filter 2 is clogged with the crushed ice, the first deicing cutoff valve 27 is opened, and the steam cutoff valve 29 and/or the compressed air cutoff valve 30 are opened while the valves installed on the first liquid inlet pipe 1 are opened, and the hot steam and/or the high pressure air is introduced into the first filter 2 and melts and removes the crushed ice in the first filter 2, and then the hot steam and/or the compressed air is discharged into the sea along with the seawater in which the crushed ice is melted through the first liquid inlet pipe 1 and the first water intake port 101. The principle of deicing in the second filter 9 is the same as that of the filter, and after the second filter 9 performs deicing, 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 described herein again. Further, when the seawater is not required to be collected, the seawater collection system provided by the embodiment can also be used for deicing the first water intake pipeline assembly and the second water intake pipeline assembly at the same time, so that the deicing efficiency is improved.
After the seawater collection system is put into operation for a period of time, some microorganisms may be attached to the system pipeline, the sampled seawater quality is polluted, and the whole system needs to be considered to be subjected to dosing, disinfection and cleaning. Therefore, the seawater collecting system provided by the embodiment further comprises a cleaning pipeline assembly.
The cleaning pipeline assembly comprises a cleaning pipe 31 for communicating a fresh water source and a cleaning agent source with the first water taking pipeline assembly and the second water taking pipeline assembly and a cleaning stop valve arranged on the cleaning pipe 31. Specifically, the upstream branch of the cleaning pipe 31 has two inlets, which are a fresh water interface 105 and a cleaning agent interface, wherein the cleaning agent interface is communicated with the cleaning agent tank 37, and the fresh water stop valve 36 and the cleaning agent stop valve 38 are installed at the fresh water interface 105 and the cleaning agent interface, respectively. The downstream of the cleaning pipe 31 is divided into a first cleaning branch pipe 32 and a second cleaning branch pipe 33, the first cleaning branch pipe 32 is communicated with the liquid inlet of the first filter 2, and the second cleaning branch pipe 33 is communicated with the liquid inlet of the second filter 9. The wash shut-off valve includes a first wash shut-off valve 34 installed on the first wash branch pipe 32 and a second wash shut-off valve 35 installed on the second wash branch pipe 33.
Further, the cleaning pipeline assembly further comprises 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 circuit for cyclically cleaning the first and second water intake pipe assemblies.
The operation mode of the purge line assembly is as follows. When the microorganism attached in the first water intake pipeline component is excessive: firstly, opening a first discharge valve 7 to discharge residual seawater in the first pipeline assembly; then the first remote control valve 5 is closed, the second remote control valve 6 and the liquid return stop valve 40 are opened, the fresh water stop valve 36 and the cleaning agent stop valve 38 are opened at the same time, and fresh water and the cleaning agent flow into the cleaning pipe 31 to be mixed to form cleaning solution. At this time, the cleaning pipe 31, the first cleaning branch pipe 32, the first inlet pipe 1 between the first remote control valve 5 and the outlet pipe 15, the outlet pipe 15 and the return pipe 39 form a first cleaning circulation loop. The first liquid pump 3 is operated to circulate the cleaning solution in the first cleaning circulation circuit, thereby continuously cleaning the first inlet pipe 1, the outlet pipe 15, the first filter 2 and the first liquid pump 3 to remove microorganisms attached to the above components. After the cleaning is finished, 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 residual cleaning solution is discharged downwards into the sea through the first liquid inlet pipe 1 and the first water intake 101.
The cleaning principle of the second water intake pipeline assembly is basically the same as that of the first pipeline assembly, and 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 102, and the specific cleaning process is not repeated herein. Further, when not needing the sea water to gather, the sea water collection system that this embodiment provided can also wash first water intaking pipeline subassembly and second water intaking pipeline subassembly simultaneously to improve cleaning efficiency.
Further, the seawater collecting system provided by the present embodiment further 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 from the pressure sensor 16, controls the opening and closing of the first liquid pump 3 and the second liquid pump 10 based on the pressure signal, and controls the open and closed states of the respective remote control valves, thereby achieving various functions such as taking water from the bottom of the ship, taking water from the side, deicing, and cleaning. The controller 23 may be a centralized or distributed controller, for example, the controller 23 may be a single-chip microcomputer or may be formed by a plurality of distributed single-chip microcomputers, and a control program may be run in the single-chip microcomputers to control the operation of each component.
All pipelines in the seawater collection system that this embodiment provided all adopt stainless steel vacuum double-walled pipe, and the evacuation has better insulating heat preservation effect between the inside and outside two-layer pipe wall of vacuum double-walled pipe to can keep the stability of sea water temperature, guarantee the authenticity of the physicochemical property of the surface layer sea water of gathering. Or, in other embodiments of the invention, the design of coating the heat-insulating layer outside the common liquid pipe can be adopted to insulate the seawater.
The working principle of the seawater collecting system provided by the embodiment is described below with reference to the accompanying drawings:
the scientific investigation ship continuously collects surface seawater through a seawater collection system in the underway process, and continuously monitors physical, chemical, biological and ecological indexes of the seawater by using a water ecological detection station arranged on the ship so as to predict and forecast the change trend of the heavy ocean phenomenon and carry out important basic support for deep research on the mechanism of the ocean process.
The seawater collecting system collects surface seawater through the first water intake pipeline component in a normal state. When seawater is collected, the ship bottom water inlet valve 4, the first remote control valve 5 and the second remote control valve 6 which are arranged on the first liquid inlet pipe 1 are all opened, the liquid outlet valve 18 which is arranged on the liquid outlet pipe 15 is opened, the first liquid pump 3 is operated, surface layer seawater is pumped into the first liquid inlet pipe 1 from the ship bottom, is filtered by the first filter 2 and finally flows into the water ecology monitoring station through the liquid outlet pipe 15. When the first liquid pump 3 works, 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 smaller than a set value, it indicates that the first filter 2 is blocked, and at this time, the controller 23 controls the second liquid pump 10 to operate and controls the first liquid pump 3 to be closed in a delayed manner.
After the first filter 2 is blocked, the second liquid pump 10 is controlled and started by the controller 23, meanwhile, the controller 23 controls the side water inlet valve 11, the third remote control valve 12 and the fourth remote control valve 13 to be opened, the second liquid pump 10 pumps surface seawater into the second liquid inlet pipe 8 from the side of the ship body, and the seawater is filtered by the second filter 9 and finally flows into the water ecology monitoring station through the liquid outlet pipe 15.
When the second water intake pipe assembly supplies water normally, the controller 23 controls the deicing pipe assembly to deice the first water intake pipe assembly at the same time.
